Definitions
- the present invention relates to a device for locking a first set to a second set located above the first set.
- the invention applies in particular to the assembly of a complete underbody unit under the body of a motor vehicle.
- the support of the body is generally constituted by a swing propelled by an overhead conveyor and the carrier base is raised to the swing by a lifting table in a berth.
- the locking member of each of the bolts carried by the carrier base engages in a recess made on the swing, then locks on a bearing surface formed on the periphery of the recess after an angular rotation of the locking member.
- this angular rotation is performed by means of levers actuated by operators, which increases the cost of assembly.
- the unlocking is achieved by means of return springs outside the locks, connected to the linkage of the manual locking mechanism.
- the object of the present invention is to create a locking device that overcomes the above drawbacks while being applicable to any application in which one must lock a first set to a second set above the first set.
- a device for locking a first assembly to a second assembly located above the first assembly comprising at least one lock fixed on the first assembly and comprising a locking member which can engage in a recess made on the second set, during a relative displacement of one of the two sets relative to the other, and lock on a bearing surface formed on the periphery of the recess by controlled angular rotation of the locking member, characterized in that it comprises an actuator for controlling the angular rotation of the locking member to lock it on said bearing surface and a return spring integrated in the latch for controlling the unlocking of the locking member of said bearing surface , and in that said locking member cooperates with the return spring so as to put it under mechanical tension during the angular rotation controlled by the actuator, the rotation in the opposite direction being prevented by the locking of the locking member on said bearing surface resulting from the mass of the first set suspended from the second set.
- the lock comprises a cylindrical portion rotatably mounted in a fixed portion relative to the first set and said return spring is a helical spring surrounding a portion integral with said cylindrical portion so that the spring is biased in torsion during said controlled angular rotation.
- this coil spring does not clutter the parts located outside the lock.
- the recess made in the second set has an oblong shape and the locking member has an oblong shape complementary to that of the recess, so that a 90 degree controlled angular rotation of this organ locking has the effect of crossing the axis of the length of the oblong shape of the locking member with the axis of the length of the oblong recess.
- This crossing of the locking member relative to the recess bears against the opposite ends of the locking member on opposite bearing surfaces located on either side of the recess which allows locking the l locking member.
- the two opposite abutment surfaces above are bordered laterally by two shoulders, which makes it possible to lock the locking member in the locking position.
- the part of the lock which is adjacent to the locking member is surrounded by a fixed guide piece whose shape is adapted to be able to engage in the oblong recess.
- This guide piece serves to guide the release of the locking member of the recess during unlocking.
- the lock comprises, between the locking member and said cylindrical portion mounted in rotation in said fixed part, a bulged portion having an annular recess in which is housed the coil spring.
- said cylindrical portion of the lock is extended opposite the locking member by a tip which is connected by a mechanism to the actuator for controlling the angular rotation of said locking member.
- the locking device comprises several identical bolts fixed on the first set and an equal number of corresponding recesses distributed on the second set so as to cooperate simultaneously with these latches.
- the invention also relates to the application of the multi-bolt device above to the assembly of a complete underbody assembly under the body of a motor vehicle, wherein the underbody assembly is carried by a base carrier and the body is carried by a support located above the carrier base and in which the carrier base is raised towards the support of the body to lock it to this support by means of locks fixed on the carrier base cooperating with corresponding recesses made in the support of the box.
- the support carrying the body is a swivel that moves continuously, the locking and unlocking of the carrier base to said support being made automatically without interrupting the movement of the support.
- the current locking and unlocking means did not allow these operations, without interrupting the movement of the swing supporting the body.
- FIG. 1 is a sectional view along a plane passing through the axis of a locking device according to the invention, the lock being unlocked
- FIG. is a perspective view of the locking device in the locked state
- FIGS. 3 to 6 are perspective views showing the successive locking steps implemented by the device according to the invention
- FIGS. 7 to 9 are similar views to Figures 3 to 6 showing the successive steps of unlocking
- Figure 10 is a schematic elevational view showing the locking made by means of several locks according to the invention between a bearing base carrying a sub-body and a swing supporting a car body
- Figure 11 is a sectional view along the plane XX of Figure 10.
- FIGS. 1 and 2 show a device for locking a first set 1 to a second set 2 situated above the first set 1, comprising a lock 3 fixed on the first set 1 assembly 1 which comprises a locking member 4 engageable in a recess 5 formed on the second assembly 2, during a relative displacement of one of the two sets relative to the other and lock on a surface of support 6, 7 made on the periphery of the recess 5 by controlled angular rotation of this locking member 4, from the unlocked position shown in Figures 1 and 2.
- the locking device comprises an actuator 8 (shown schematically in FIG. 1) for automatically controlling the angular rotation of the locking member 4 in order to lock it on the bearing surfaces 6, 7 and a return spring 9 integrated in the lock 3 to control the unlocking of the locking member relative to the bearing surfaces 6, 7.
- the locking member 4 cooperates with the return spring 9 so as to put the under mechanical tension during the angular rotation controlled by the actuator 8.
- the latch 3 comprises a cylindrical portion 10 rotatably mounted in a fixed portion li in the form of a fixed sleeve relative to the first assembly 1.
- the return spring 9 is a helical spring surrounding a part 10a extending upwards the cylindrical part 10, so that this spring is biased in torsion during the angular rotation controlled by the actuator 8.
- the recess 5 made in the second assembly 2 has an oblong shape and the locking member 4 has an oblong shape complementary to that of the recess 5, so that a controlled angular rotation 90 degrees by the actuator 8 of this locking member 4 has the effect of crossing the axis of the length of the oblong shape of the locking member 4 with the axis of the length of the oblong recess 5, as shown in Figure 2.
- FIG. 2 shows that in the locking position, the opposite ends of the locking member 4 rest on two surfaces.
- opposed 6, 7 located on either side of the recess 5 and laterally bordered by shoulders 12, 13 which laterally block the member 4.
- the part 10b of the latch which is adjacent to the locking member 4 is surrounded by two fixed guide parts 14, 15 whose shape is adapted so that the upper ends 14a, 15a of these parts can engage in the oblong recess 5, as shown in particular in Figure 1, so as to guide the engagement of the locking member 4 in the recess 5.
- Figures 1 and 2 show further that the lock 3 comprises between the locking member 4 and the cylindrical portion 10 rotatably mounted in the sleeve 1 1, a bulged portion 16 having an annular recess 17 in which is housed the helical spring 9.
- This bulged portion 16 carries (see Figure 2) a radial projecting portion 18 which serves as a stop to limit the rotation of the latch 3 to the locked position.
- This abutment is supported against one of the two uprights 19 which connect the two guide pieces 15 to the base 20 of the sleeve 1 1 which is fixed to the assembly 1.
- the cylindrical portion 10 is extended to the opposite the locking member 4 by a nozzle 21a which is connected (see Figure 1) to a mechanism 8a to the actuator 8 for controlling the angular rotation of the locking member 4.
- the mechanism 8a can be for example of the type for transforming a linear motion into a rotational movement.
- FIG. 3 illustrates the successive steps of locking.
- step 1 shown in FIG. 3 the latch 3 fixed on the assembly 1 moves in a vertical movement towards the recess 5 of the assembly 2.
- step 2 the locking member 4 of the lock is engaged in the recess 5.
- step 3 the locking member 4 has turned from
- step 4 the assembly 1 is lowered to put the locking member 4 in abutment on the bearing surfaces 6, 7 shown in FIG. 2.
- the mass of the assembly 1 ensures the irreversibility of the lock.
- FIGS 7 to 9 illustrate the successive steps of unlocking.
- the return spring 9 of the lock automatically rotates the locking member 4 by 90 degrees in the opposite direction to the rotation controlled by the actuator. The lock is then unlocked from the assembly 2 without any actuator or manual intervention of an operator.
- FIGS 10 and 11 illustrate a preferred application of the locking device described above.
- the locking device comprises several identical locks 3, 3a fixed on the first set 1 and an equal number of corresponding recesses 5 distributed on the second set 2 so as to cooperate simultaneously with these locks.
