Description

Technical Field

[0001] This utility model belongs to the field of automotive inspection tool technology, specifically relating to an automotive inspection tool trimming and positioning device. Background Technology

[0002] Automotive inspection fixtures are specialized tools used to inspect automotive parts. By matching and measuring the parts, they verify whether the dimensions, shape, positional accuracy, and assembly relationships meet the requirements of the design drawings. This ensures the manufacturing precision and consistency of the parts, and provides a guarantee for the quality of automotive assembly and overall performance.

[0003] In automotive fixture processing, trimming is used to remove burrs, flash, and excess material generated during processing. This prevents these defects from affecting the positioning accuracy and measurement accuracy during inspection, or from scratching the automotive parts being inspected. At the same time, it ensures that the edge dimensions of the fixture match the assembly and usage requirements. Trimming is usually done by manual filing, sanding, or mechanical grinding to finely refine the edges until they meet the tolerance range and smooth and flat requirements specified in the design drawings.

[0004] Existing devices often rely on manual operation to complete positioning, which is not only inefficient but also prone to affecting positioning accuracy due to human error. Their positioning structures are mostly unidirectional limiting, making it difficult to stably fix the workpiece from multiple dimensions, resulting in poor positioning stability.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Please see Figure 1-4 This utility model provides an automotive tool trimming and positioning device, including a placement platform 1, a placement box 2 rotatably connected inside the placement platform 1, a placement cavity 3 opened on the top of the placement box 2, and a positioning component 4 provided on the top of the placement box 2. The positioning component 4 includes a limiting slide groove 401 opened on the top of the placement box 2 and arranged in a circular array. A limiting slider 402 is slidably connected inside the limiting slide groove 401. A buffer pad 403 is fixedly connected to the side of the limiting sliders 402 that are close to each other. A lever 404 is fixedly connected to the bottom of the limiting slider 402. A lever 405 is rotatably connected inside the placement box 2. An arc-shaped groove 406 arranged in a circular array is opened inside the lever 405. A rotary motor 407 is fixedly connected to the bottom of the lever 405. The lever 404 is located inside the arc-shaped groove 406, and the end of the buffer pad 403 away from the limiting slider 402 is arc-shaped.

[0023] After the rotary motor 407 starts, it drives the lever 405 to rotate. Since the lever 404 is located in the arc-shaped groove 406 of the lever 405, the arc-shaped groove 406 will generate a pushing force on the lever 404 when the lever 405 rotates, causing the limiting slider 402 to slide radially in the limiting groove 401. When the limiting sliders 402 approach each other, the buffer pad 403 on one side can clamp and position the automotive fixture workpiece placed above the placement cavity 3. The end of the buffer pad 403 away from the limiting slider 402 is arc-shaped, which can better fit the surface of the arc-shaped workpiece. This utility model achieves automatic positioning by driving the rotary motor 407, eliminating the need for manual operation and improving positioning efficiency. The ring array of limiting grooves 401 and limiting sliders 402 can position the workpiece from multiple directions, ensuring positioning stability. The buffer pad 403 can avoid direct rigid contact between the limiting slider 402 and the workpiece, reducing wear on the workpiece surface.

[0024] Specifically, such as Figure 1 As shown, an adjustment assembly 9 is provided on the top of the placement platform 1. The adjustment assembly 9 includes an electric telescopic rod 901 fixedly installed on the top of the placement platform 1 and a toothed groove 904 opened on the side surface of the placement box 2. A connecting block 902 is fixedly connected to the telescopic end of the electric telescopic rod 901. A rack 903 is fixedly connected to the side of the connecting block 902 near the placement box 2. The rack 903 and the placement box 2 are connected by meshing through the toothed groove 904.

[0025] When the electric telescopic rod 901 extends or retracts, it drives the connecting block 902 to move, which in turn causes the rack 903 to move synchronously. Since the rack 903 meshes with the toothed groove 904 on the side surface of the placement box 2, the movement of the rack 903 causes the placement box 2 to rotate within the placement platform 1, thereby adjusting the angle of the placement box 2 and the workpiece above it. This invention achieves electric adjustment of the angle of the placement box 2 through the electric telescopic rod 901, facilitating the adjustment of the workpiece's posture according to trimming requirements. It is convenient to operate and offers high adjustment precision. The stable meshing transmission between the rack 903 and the toothed groove 904 ensures that the placement box 2 will not shake during angle adjustment.

[0026] Specifically, such as Figure 1 As shown, the inner wall of the placement cavity 3 is provided with a spiral pattern 5, and the interior of the placement cavity 3 is threadedly connected to a placement bowl 6 through the spiral pattern 5. Several annular support brackets 7 are fixedly connected inside the placement bowl 6, and handles 8 are fixedly connected inside the support brackets 7. Several support legs 10 are fixedly connected to the bottom of the placement platform 1, and anti-slip pads 11 are fixedly connected to the bottom of the support legs 10.

[0027] The placement bowl 6 is threadedly connected to the inner wall of the placement cavity 3 via a spiral thread 5 on its outer side wall, and can be fixed inside the placement cavity 3. The annular support 7 inside the placement bowl 6 supports the bottom of the workpiece. The placement bowl 6 can be rotated via the handle 8 to install and remove it from the placement cavity 3. In this invention, the spiral thread 5 connection ensures that the placement bowl 6 is firmly installed and easy to disassemble and replace, thus facilitating the cleaning of dust generated during internal grinding; the support 7 provides stable support for the bottom of the workpiece, preventing the workpiece from tilting during trimming; and the handle 8 allows operators to quickly install and remove the placement bowl 6.

[0028] Working principle and usage process of this utility model:

[0029] When the operator is operating the equipment, firstly, the placement bowl 6 is screwed into the placement cavity 3 and fixed by the spiral pattern 5 using the handle 8. Then, the automotive inspection tool workpiece is placed into the placement bowl 6, and the bottom of the workpiece is supported by the internal annular support 7. Then, the rotary motor 407 of the positioning component 4 is started. The motor drives the lever 405 to rotate, and the arc groove 406 pushes the lever 404, so that the limit slider 402 slides radially along the limit groove 401. The workpiece is clamped from multiple directions by the buffer pad 403 to complete the positioning.

[0030] According to the trimming requirements, the electric telescopic rod 901 of the control adjustment component 9 is extended and retracted, which drives the connecting block 902 and the rack 903 to move. The meshing transmission between the rack 903 and the tooth groove 904 is used to make the placement box 2 rotate in the placement table 1 to adjust the workpiece angle. Throughout the process, the support leg 10 and anti-slip pad 11 at the bottom of the placement table 1 ensure the stability of the device.

[0031] After the trimming is completed, the reverse rotation motor 407 is started to reset the limit slider 402, and the workpiece is removed. If cleaning is required, the placement bowl 6 can be unscrewed from the placement cavity 3 through the handle 8.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
