Description of the embodiments
The utility model is further described below in connection with the accompanying drawings, without any limitation to the utility model, and any limited number of modifications made by anyone within the scope of the claims of the utility model remain within the scope of the claims of the utility model.
As shown in fig. 1, the two-stroke engine cylinder block inspection fixing tool comprises a support frame 1, a fixing block 2 and a fixing bolt 3, wherein the upper end of the support frame 1 is connected with the fixing block 2 through the fixing bolt 3, and the lower end of the support frame is connected with a marble table top of a three-coordinate measuring machine through the fixing bolt 3; the cylinder block 4 is fixed to the inspection tool by the fixing bolts 3.
The specific operation flow is as follows: placing the support frame 1 on the marble table surface of the three-coordinate measuring machine, enabling the bottom plate of the support frame 1 to be parallel to the marble table surface of the three-coordinate measuring machine, enabling the mounting hole of the bottom plate of the support frame 1 to be aligned with the threaded hole of the marble table surface of the three-coordinate measuring machine by adjusting the positions of the bottom plate of the support frame 1, fixing the support frame 1 on the marble table surface of the three-coordinate measuring machine by using the fixing bolt 3, fixing the fixing block 2 on the upper end surface of the support frame 1, adjusting the vertical surface of the fixing block 2 to be parallel to the X-axis moving direction of the three-coordinate measuring machine, and enabling the protruding end to be consistent with the X-axis direction of the three-coordinate measuring machine. Therefore, the cylinder block inspection fixing tool can be stably installed on a marble table top of a three-coordinate measuring machine, the end face of the vent hole flange of the cylinder block 4 to be inspected is combined with the lower surface of the fixed block 2, the threaded hole of the end face of the vent hole flange is aligned with the fixing hole 21 and the adjustable hole 22 on the fixed block 2, the upper end face of the cylinder block 4 faces forwards, the fixing bolt 3 is used for fastening, and in order to ensure that the clamping positions of the cylinder blocks 4 with the same specification are consistent, the fixing bolt 3 positioned on the fixed block 2 is installed after, and the cylinder block 4 is fixed.
The upper end face of the bottom plate of the support frame 1 is combined with the lower surface of the fixed block 2, and the fixed block 2 is vertical to the support frame 1, so that the cylinder body 4 is placed in a horizontal state. The fixing bolt 3 is used for attaching and connecting the flange end face of the exhaust hole of the cylinder body 4 with the lower surface of the fixing block 2, so that the cylinder body 4 is prevented from swinging back and forth, left and right, up and down. And locking the front and back directions by using a three-coordinate measuring machine, and leveling the flange end face of the exhaust hole of the cylinder body 4. By slightly adjusting the position of the support frame 1, the end face of the vent hole flange of the cylinder body 4 is ensured to be parallel to the three-coordinate XZ plane.
When the cylinder block 4 is horizontally fixed on the inspection fixture, the three-coordinate measuring machine can be used for detecting all the size sampling points of the cylinder block 4 by using the horizontal angle measurement, and the measured size is more, so that the performance parameters of the cylinder block 4 can be comprehensively evaluated.
When the cylinder body 4 is inspected, when other cylinder bodies 4 to be measured are replaced, only the fixing bolts 3 connected with the flange end faces of the exhaust holes of the cylinder body 4 are required to be loosened, the cylinder body 4 to be measured is horizontally placed under the supporting frame 1, the flange end faces of the exhaust holes of the cylinder body 4 are attached to the lower surfaces of the fixing blocks 2, the cylinder body 4 and the fixing blocks 2 are connected together by the fixing bolts 3, and the fixing bolts 3 positioned in the fixing holes 21 are close to the rear ends, so that the cylinder body 4 can be stably and accurately placed at the same position, and a coordinate system is not required to be established by manually operating three-coordinate handle sampling points for each measurement, so that the inspection efficiency can be greatly improved.
