Abstract

(57) [Abstract] [Purpose] To reduce the deformation of the fixed part when crimping the crimping part that holds the bilaterally asymmetrical support part to the crimping part, and to make the crimping part small and perform the crimping fixing efficiently. To aim for things. According to the present invention, the caulking fixing force is strong in the direction in which the supporting portion 6 is present and weak in the direction in which the supporting portion is not present, and the caulking fixing force is changed and fixed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to fixing in a caulking.

[0002]

[Prior art]

 Conventionally, this type of caulking is performed by symmetrically forming a split angle with respect to the center of the caulking portion, and fixing the caulking portion of the shaft at the same angle in the left and right or front and back.

Also, with respect to caulking in one direction, the caulking portion was split at the same angle from the center of the chisel, and the caulking portion was opened left or right or front and back.

The caulking strength has been secured by increasing the caulking pressure or increasing the amount of caulking.

[0005]

[Problems to be solved by the device]

 In the above-mentioned conventional technology, with respect to the deformation of the part to be caulked and the strength of the fixing base, the design change for increasing the strength such as the material of the part and the thickness of the part, the supporting area of the caulking part, and the caulking area Was supported by.

[0006]

[Means for Solving the Problems]

 The present invention has a caulking component that holds a left and right or front and rear asymmetrical supporting portion with respect to the caulking component, a fixing component that abuts the supporting component and is fixed to the caulking component, and a caulking component that impacts and deforms the caulking component. The feature is that the fixing force of the caulking part is changed by changing it to the left or right or the front and back. Further, it is characterized in that the fixing force of the caulking portion is fixed only on one side.

[0007]

[Action]

 According to the above-mentioned structure of the present invention, the pressure applied to the fixed part changes by changing the fixing force of the caulking, so that the deformation of the fixed part can be reduced.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a view of the present invention used for fixing by crimping. Reference numeral 1 is a caulking component, which is formed of a ductile and malleable material such as metal. Reference numeral 2 denotes a fixed component, which is fixed by crimping the crimped component 1. Further, the fixed component 2 has a hole portion into which the crimp portion 3 is inserted. Assemble the caulking portion 3 of the caulking component 1 into the hole of the fixing component 2 and set it on the caulking fixture base. In the caulking portion 3, chisel for fixing by caulking descends from above. Then, by further applying a pressure in the descending direction, the caulking portion 3 is cracked to the left and right, and the caulking portions 3A and 3B come into contact with or bite into the fixed component 2 to fix it.

To explain the caulking condition in detail, the caulking portion 3 is divided into 3A and 3B by a chisel. Then, by increasing the falling stroke of the chisel, 3A and 3B contact the fixed component 2. Further, by applying downward pressure to the chisel, the caulking portions 3A and 3B bite into the fixed component 2. By this contact or bite, the fixed part 2 is subjected to the crimping pressure in the a direction by the fixed parts 4 and 5 of the crimped part 1. Since the fixing portion 5 of the caulking component 1 has the indicating portion 6, the crimping pressure can be received as the clamping pressure between the fixing portion 5 and the supporting portion 6. That is, since the fixed portion 5 of the fixed component 2 has the support portion 6, it is difficult to deform due to the crimping pressure. On the other hand, since the fixed portion 4 of the fixed component 2 does not have a cradle like the support portion 6, the fixed component 2 is easily deformed. The caulking pressure applied to the fixed parts 4 and 5 is strong for the fixed part 5 with the support part 6 and weak for the fixed part 4 without the support part. Was done.

Next, a second embodiment of the present invention will be described. FIG. 2 is a diagram showing the fixing by caulking. The caulking structure is the same as that of the first embodiment, but even when the supporting part is provided, the caulking parts 13A and 13B of the caulking component 11 are provided by providing only the fixing parts 14 and 15 that require the fixing force. It can be made smaller and can be caulked more efficiently.

[0011]

[Effect of device]

 As described above, according to the present invention, the amount of deformation of parts can be minimized or the area of the caulked portion can be reduced by changing the fixing force by the caulking of the fixed portion between left and right or front and back. I can.
