Description

Technical Field

[0001] This utility model relates to the field of component testing technology, and in particular to an auxiliary device for testing bracket assemblies. Background Technology

[0002] The car bumper is connected to the vehicle by a bracket, and the bracket affects the installation accuracy and overall strength. The bracket assembly needs to be tested after the bracket is manufactured.

[0003] A search revealed a prior art inspection tool for automotive bumper bracket assembly (publication number: CN216594105U) that facilitates positioning and inspection. This tool includes an inspection platform and a tool body mounted on the platform. The tool body is characterized by an auxiliary positioning component on the inspection platform. This component includes a support assembly fixed below the inspection platform and a correction assembly mounted on both sides of the tool body. The support assembly includes a support frame fixed to the bottom of the inspection platform, a guide rail on the support frame, multiple sliding blocks that slide with the guide rail, drive blocks fixed to the sliding blocks, and a pneumatic support rod fixed to the drive blocks. The tool body has a through groove in the middle for the pneumatic support rod to move. The top of the pneumatic support rod has a suction cup device. The correction assembly includes a pair of horizontally opposed cylinders fixed to the surface of the inspection platform and a pair of vertical clamping plates. One side of the horizontally opposed cylinder drives the movement of the vertical clamping plate on the same side.

[0004] In the prior art, once the support assembly is fixed on the testing table, its position cannot be changed. The strength test of the support is multi-point. After the position of the support assembly is fixed, it is difficult to adjust the position to be tested, which will affect the multi-point test and the test results. There is room for optimization.

[0005] Therefore, we propose an auxiliary device for testing stent assemblies. Utility Model Content

[0006] The present invention mainly solves the technical problem of the fixed and unadjustable position of the workpiece to be inspected, and provides an auxiliary device for testing bracket assembly.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a bracket assembly testing auxiliary device, comprising:

[0008] A base, on one side of which an electric pull rod is fixedly installed, and a pressure plate is fixedly installed on the output shaft of the electric pull rod. A support plate for lifting the workpiece is also fixedly installed on the top of the base.

[0009] An extension structure, located on the side of the support plate, is used to adjust the lifting position. The extension structure includes two slides that slide along the base and rollers that are rotatably connected to the slides.

[0010] In a preferred embodiment of this utility model, a pad is detachably connected to the top of the support plate, and the top of the pad is provided with several anti-slip grooves.

[0011] In a preferred embodiment of this utility model, the support plate is a rectangular block, located directly below the pressure plate, and the top of the support plate has a groove for mounting a pad, with the pad being interference-fitted to the groove.

[0012] In a preferred embodiment of this utility model, the pad is a rectangular plate with a hollow interior, and the anti-slip groove is a groove with a V-shaped horizontal cross-section, with multiple anti-slip grooves evenly distributed on the top surface of the pad.

[0013] In a preferred embodiment of this utility model, the extension structure further includes a guide rail and a lead screw. The guide rail is fixedly installed on the top of the base, the slide is slidably connected to the guide rail, the lead screw is rotatably connected to the base, and the lead screw is threadedly connected to the slide.

[0014] In a preferred embodiment of this utility model, the extension structure further includes a guide hole and a threaded sleeve. The slide table passes through the guide hole, the guide rail is slidably disposed within the guide hole, the threaded sleeve is fixedly connected to the slide table, and the lead screw is threadedly connected to the threaded sleeve.

[0015] In a preferred embodiment of this utility model, the top of the base is provided with two parallel guide rails, the slide has two guide holes, the guide rails are adapted to the guide holes, and the threaded sleeve passes through the slide.

[0016] This utility model provides an auxiliary device for testing bracket assemblies. It has the following beneficial effects:

[0017] 1. This auxiliary testing device for a bracket assembly uses a lead screw to rotate and move a threaded sleeve to slide a slide table. The slide table slides radially along a guide rail. The lead screw is a bidirectional lead screw, which moves two slide tables synchronously and in opposite directions to adjust the support position. This allows for easy adjustment of the workpiece's suspended position for testing, offering greater flexibility and more comprehensive testing. It enables testing of multiple points on the bracket. By pressing the suspended position of the bracket with a push rod, shear resistance and impact resistance can be tested. The position of the slide table can be flexibly adjusted to meet the needs of multi-point testing of the workpiece and adjustment of the support position.

[0018] 2. This bracket assembly testing auxiliary equipment uses the output shaft of an electric pull rod to pull the pressure plate down to fix the workpiece, while the support plate and pad provide support at the bottom of the workpiece. The deformable pad, combined with the design of multiple anti-slip grooves, can ensure sufficient contact force between the workpiece and the pad, resulting in better workpiece limiting effect while avoiding hard contact, thus balancing limiting effect and workpiece protection performance.

[0025] A support assembly testing auxiliary device, such as Figure 1 and Figure 2 As shown, it includes:

[0026] The base 10 has an electric pull rod 11 fixedly installed on one side, and a pressure plate 12 fixedly installed on the output shaft of the electric pull rod 11. A support plate 13 for lifting the workpiece is also fixedly installed on the top of the base 10.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a pad 14 is detachably connected to the top of the support plate 13. The top of the pad 14 is provided with several anti-slip grooves 15. The support plate 13 is a rectangular block. The support plate 13 is located directly below the pressure plate 12. The top of the support plate 13 is provided with a groove for installing the pad 14. The pad 14 is interference-fitted with the groove. The pad 14 is a rectangular plate. The inside of the pad 14 is hollow. The anti-slip grooves 15 are grooves with a horizontal cross section in the shape of a V. Multiple anti-slip grooves 15 are evenly distributed on the top surface of the pad 14.

[0028] In this design, the base 10 is a rectangular plate with mounting holes at its four corners. The base 10 is fixed to the testing frame with screws and is mainly used for testing the bracket assembly of automotive bumpers, especially the impact resistance and shear strength of the bracket. The testing frame needs to be equipped with a push rod. The output shaft of the push rod moves perpendicular to the top surface of the base 10 and presses the bracket placed on the support plate 13. The output shaft of the electric pull rod 11 pulls the pressure plate 12 down to fix the workpiece. The support plate 13 and the pad 14 provide support at the bottom of the workpiece. The deformable pad 14, with multiple anti-slip grooves 15, can ensure sufficient contact force between the workpiece and the pad 14, resulting in better workpiece limiting effect while avoiding hard contact, thus balancing limiting effect and workpiece protection performance.

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, the extension structure is located on the side of the support plate 13 for adjusting the lifting position. The extension structure includes two slides 20 that slide along the base 10, and a roller 23 rotatably connected to the slides 20. The extension structure also includes a guide rail 21 and a lead screw 22. The guide rail 21 is fixedly installed on the top of the base 10. The slides 20 are slidably connected to the guide rail 21, and the lead screw 22 is rotatably connected to the base 10. The lead screw 22 is threadedly connected to the slides 20. The extension structure also includes a guide hole 24 and a threaded sleeve 25. The guide hole 24 is opened through the slides 20. The guide rail 21 is slidably installed in the guide hole 24. The threaded sleeve 25 is fixedly connected to the slides 20. The lead screw 22 is threadedly connected to the threaded sleeve 25. Two parallel guide rails 21 are provided on the top of the base 10. The slides 20 have two guide holes 24. The guide rails 21 are adapted to the guide holes 24. The threaded sleeve 25 passes through the slides 20.

[0030] In this solution, considering the potential differences in the length of the support and the need to inspect multiple points on the support, the shear strength and impact resistance can be tested by pressing the suspended position of the support with a push rod. Therefore, the position of the slide table 20 needs to be flexibly adjusted to meet the requirements of multiple workpiece inspections and support position adjustment. A motor is fixedly installed on one side of the base 10, and the motor output shaft is fixedly connected to the lead screw 22. Alternatively, the lead screw 22 can be manually rotated to drive the slide table 20. The rotation of the lead screw 22 moves the threaded sleeve 25 to slide the slide table 20. The slide table 20 slides radially along the guide rail 21. The lead screw 22 is a bidirectional lead screw. By moving the two slide tables 20 synchronously and in opposite directions, the support position can be adjusted, making it convenient to adjust the suspended position of the workpiece for inspection. This provides greater flexibility and more comprehensive inspection.

[0031] The working principle of this utility model is as follows: The bracket to be inspected is placed on the support platform 13. The output shaft of the electric pull rod 11 is lowered, the pressure plate 12 moves down and presses the workpiece onto the pad. The anti-slip groove 15 on the pad 14 inhibits the slippage of the workpiece. The lead screw 22 rotates and moves the threaded sleeve 25 to drive the slide table 20 to slide. The slide table 20 slides radially along the guide rail 21. The lead screw 22 is a bidirectional lead screw. By moving the two slide tables 20 synchronously and in opposite directions, the support position can be adjusted, which facilitates the adjustment of the suspended position of the workpiece for inspection. A push rod needs to be installed on the inspection frame. The output shaft of the push rod moves perpendicular to the top surface of the base 10 and presses the bracket placed on the support plate 13. The impact resistance and shear resistance of the workpiece are tested by pressing the suspended part of the workpiece. Of course, the motor and electric pull rod 11 need to be connected to a power supply and a controller for use, which will not be described in detail here.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
