Description

Technical Field

[0001] The utility model relates to a stamping positioning fixture for a reinforcing plate of an automobile safety belt. Background Art

[0002] Automobile seat belts are safety devices that restrain passengers in the event of a collision and prevent passengers from having a secondary collision with the steering wheel, dashboard, etc., or from being rushed out of the car and causing death or injury. In order to increase the connection strength between the two ends of the seat belt and the car frame, reinforcement plates are usually installed at both ends of the seat belt. Currently, most reinforcement plates are sheet metal parts, so the processing method is stamping, and the stamping steps of the reinforcement plates are mainly bending and punching. In order to ensure that the reinforcement plates do not shift during stamping, it is usually necessary to use a positioning device on the stamping equipment.

[0003] Since one side edge of the seat belt reinforcement plate is designed with a flange, a row of mounting holes needs to be punched out on the flange. However, the inside of the flange is hollow, and direct stamping will cause the flange to deform. Also, since there is a step inside the flange, the existing positioning device cannot automatically extend into the inside of the flange, and the pad must be manually inserted into the flange from left to right to play a supporting role before the punching operation can be performed. After the punching is completed, the pad must be pulled out in the reverse direction. Therefore, the operation steps are relatively cumbersome, resulting in low processing efficiency, which is time-consuming and labor-intensive, and needs further improvement. Utility Model Content

[0004] In view of the current status of the above-mentioned prior art, the technical problem to be solved by the utility model is to provide a stamping positioning fixture for a car seat belt reinforcement plate which simplifies the operation steps to improve the processing efficiency and achieve the effect of saving time and labor.

[0028] Working principle:

[0029] The telescopic end of the lifting cylinder 24 in the driving positioning assembly 2 retracts inward to drive the pressure plate 26 to move upward with the help of the traction mechanism 25, and at the same time drives the telescopic end of the positioning cylinder 271 in the positioning unit 27 to extend outward to drive multiple positioning blocks 274 to move upward with the help of the lifting beam 272 and the U-shaped beam 273.

[0030] Next, the safety belt reinforcement plate is placed horizontally from front to back on the top of the support block 29 with the flange on one side facing backwards, until the rear outer wall of the safety belt reinforcement plate is attached to each second L-shaped limit frame 211 to determine the front and rear position of the safety belt reinforcement plate, and the opening of the flange is set forward; and the left and right ends of the safety belt reinforcement plate are respectively attached to the inner sides of the two first L-shaped limit frames 210 to prevent the safety belt reinforcement plate from moving left and right.

[0031] Then drive the telescopic end of the positioning cylinder 271 to retract inward to drive multiple positioning blocks 274 to move downward in the same way, until the limiting segment 2745 on each positioning block 274 is located in front of the opening of the flange on the seat belt reinforcement plate, and the bottom of each limiting segment 2745 is not in contact with the seat belt reinforcement plate; then pull the seat belt reinforcement plate forward to move its flange forward until the end of each limiting segment 2745 is inserted into the flange; then continue to drive the telescopic end of the positioning cylinder 271 to retract inward to drive multiple positioning blocks 274 to continue to move downward until the bottom of each limiting segment 2745 is pressed against the lower inner wall of the flange, thereby completing the fixation of the seat belt reinforcement plate, and the top of each limiting segment 2745 is attached to the upper inner wall of the flange.

[0032] A plurality of vertically arranged stamping columns 3 are installed on the bottom front edge of the pressure plate 26. After the seat belt reinforcement plate is fixed, the telescopic end of the lifting cylinder 24 is driven to extend outward to drive the pressure plate 26 to move downward in the same way, and then the upper outer wall of the flange is punched with the help of the plurality of stamping columns 3.

[0033] The utility model can, with the help of each positioning block 274 in the positioning unit 27, extend from the front opening of the flange into the interior of the flange and automatically press it, which can not only fill the hollow structure inside the flange to prevent the flange from deforming, but also better adapt to the step structure inside the flange, thereby eliminating the steps of inserting and withdrawing the cushion strip, thereby simplifying the operating steps to improve the processing efficiency and achieve the effect of saving time and effort.
