Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to an automotive parts grinding and clamping device. Background Technology

[0002] With the rapid development of the automotive industry, higher requirements have been placed on the quality and processing precision of automotive parts. Automotive parts are diverse in type and complex in shape, and the processing must ensure their structural strength and assembly precision to meet actual usage needs.

[0003] In the manufacturing process of automotive parts, the frame plates of the parts typically require grinding to improve overall manufacturing efficiency and product consistency. During operation, a pre-fabricated positioning plate is installed on the machining table, and the part to be processed is then fixed within the positioning plate for grinding and other treatments. While this method provides some positioning functionality, the wide variety of vehicle models and parts necessitates the customization of multiple positioning plates based on different sizes and structures. This not only results in high costs and cumbersome switching but also impacts overall operational efficiency and processing flexibility. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing process requires frequent replacement of the positioning plate, which is complicated, inefficient, and difficult to adapt to the rapid processing needs of multi-specification parts.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a grinding and clamping device for automotive parts, including a frame, two horizontally arranged transverse grooves are opened in the center of the frame, a bidirectional push rod motor is fixedly installed at the center of the transverse grooves, a connecting rod is fastened to the output end of the bidirectional push rod motor, the connecting rod is perpendicular to the output end of the bidirectional push rod motor, a number of evenly spaced screw holes are opened on the connecting rod, a clamping seat is fastened to the screw holes by bolts, a push motor is fixedly installed on both sides of the clamping seat, a combination block is fixedly installed at the output end of the push motor, and a number of clamping crossbars for clamping automotive frame-shaped parts are fastened to the combination block by bolts.

[0006] As a further improvement of this utility model, the output end of the bidirectional push rod motor is fixedly connected to a guide block, and the inner walls on both sides of the transverse groove are provided with sliding grooves for the guide block to slide.

[0007] As a further improvement of this utility model, a fitting groove is provided on one side of the bottom end of the connecting rod, which fits into the center of the guide block, and the connecting rod is threadedly connected to the guide block by a bolt passing through the fitting groove.

[0008] As a further improvement of this utility model, the combined block is configured as a T-shaped block structure, and multiple bolts are fastened around it.

[0009] As a further improvement of this utility model, the plurality of clamping crossbars include two first crossbars and two second crossbars. The first crossbars are located at the top and bottom of the assembly block, and the second crossbars are located at the center side of the assembly block. Both the first crossbars and the second crossbars are fastened to the assembly block by bolts.

[0010] As a further improvement of this utility model, a cushioning pad is adhered to the center side of the first horizontal bar and the second horizontal bar.

[0011] The beneficial effects of this utility model are as follows: This utility model uses a frame as its supporting foundation, with a centrally located bidirectional push rod motor that drives a connecting rod to achieve bidirectional horizontal movement. This, in turn, through clamping seats screwed onto the connecting rod, drives the clamping system to adjust synchronously left and right, making the clamping operation more flexible and precise. The push motor drives the relative position of the clamping crossbars via a combination block, allowing for fine-tuning. The combination block adopts a T-shaped structure design, reliably fixing multiple clamping crossbars with bolts, facilitating multi-point stable clamping. The matching guide block cooperates with the sliding grooves on both sides of the crossbar, forming a stable and smooth sliding guide mechanism under motor drive, effectively preventing lateral swaying and improving the reliability and repeatability of the clamping action. It can quickly clamp and position frame-shaped workpieces of different sizes, significantly improving work efficiency and stability, reducing the frequency of manual adjustments, and ensuring subsequent grinding accuracy.

It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] This utility model provides the following: Figure 1-4 As shown, an automotive parts grinding and clamping device includes a frame 1. The frame 1 has two horizontally arranged transverse grooves at its center. A bidirectional push rod motor 2 is fixedly installed at the center of each groove. A connecting rod 3 is fastened to the output end of the bidirectional push rod motor 2. The connecting rod 3 is perpendicular to the output end of the bidirectional push rod motor 2. Several evenly spaced screw holes are opened on the connecting rod 3. A clamping seat 4 is fastened to each screw hole by bolts. Push motors 5 are fixedly installed on both sides of the clamping seat 4. A combination block 6 is fixedly installed at the output end of the push motor 5. Multiple clamping crossbars for clamping automotive frame-shaped parts are fastened to the combination block 6 by bolts.

[0021] As attached Figure 1-4 As shown, a guide block 7 is fixedly connected to the output end of the bidirectional push rod motor 2, and sliding grooves are provided on the inner walls of both sides of the transverse groove for the guide block 7 to slide; this improves the guiding effect when the output end of the bidirectional push rod motor 2 and the connecting rod 3 move. A fitting groove 8 is provided on one side of the bottom end of the connecting rod 3, which fits into the center of the guide block 7, and the connecting rod 3 is threadedly connected to the guide block 7 by a bolt passing through the fitting groove 8.

[0022] As attached Figure 4As shown, the assembly block 6 is designed as a T-shaped block structure, with multiple bolts tightly fastened around its perimeter; this allows the user to easily assemble the multiple clamping crossbars onto the assembly block 6 using an electric screwdriver. The multiple clamping crossbars include two first crossbars 9 and a second crossbar 10. The first crossbars 9 are located at the top and bottom of the assembly block 6, and the second crossbar 10 is located at the center of the assembly block 6. Both the first crossbars 9 and the second crossbar 10 are fastened to the assembly block 6 with bolts to reinforce the structural integrity. A cushioning pad is adhered to the center of the first crossbars 9 and the second crossbar 10; this cushioning pad effectively prevents excessive clamping, which could cause wear on the paint surface of the components.

[0023] Working Principle: In practical implementation, the operator places the automotive frame component to be processed in the central area of ​​the frame 1. By controlling the bidirectional push rod motor 2, the connecting rod 3 moves left and right along the transverse groove to adapt to the width of the automotive component frame. Then, according to the height of the automotive component, the clamping seat 4 is screwed into the corresponding screw holes of the connecting rod 3. The two first horizontal bars 9 are then screwed into one side of the assembly block 6. By synchronously starting the two push motors 5, the two first horizontal bars 9 on one side of the assembly block 6 abut against the bottom corner of the frame. The operator then assembles the corresponding second horizontal bars 10 and the bolts on both sides with the assembly block 6, so that the second horizontal bars 10 abut against the bottom corner of the frame from the other side, thus completing the assembly operation and achieving reliable clamping of the workpiece for subsequent grinding.
