DETAILED DESCRIPTION

[0025] The technical scheme of the utility model will be described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model. EMBODIMENT

[0026] In the modern mechanical processing industry, double-end surface grinding machine as high-precision processing equipment, its application is increasingly widespread. In order to further enhance the processing efficiency and precision, an innovative splicing type double-end surface grinding machine positioning tooling emerges as the times require. This paper will elaborate the design principle, structure characteristics and advantages of this tooling in practical application, and through rich details, examples, quotations and statistical data, its excellent performance is fully displayed.

[0027] With the rapid development of manufacturing industry, higher requirements are put forward for the machining precision and efficiency of parts. The traditional positioning tooling often has the problems of complex structure, inconvenient adjustment, poor adaptability, etc., which is difficult to meet the modern processing demand. Therefore, the research and development team designs this splicing type double-end surface grinding machine positioning tooling for these problems. The tooling realizes quick assembly and disassembly through modular design, while ensuring high-precision positioning, greatly improving the processing efficiency and flexibility.

[0028] Please refer to Figure 1 - Figure 5 As shown in the figure, the tooling base plate 1 is made of high-strength and high-wear-resistant material, which ensures the stability and durability under long-term use. At the corner of the tooling base plate 1, there are multiple mounting hole positions 5, which are precisely processed to ensure accurate docking with the double-end surface grinding machine. Through bolts and other fasteners, the tooling base plate 1 can be firmly fixed on the grinding machine to provide stable support for subsequent processing.

[0029] The rotary handle 3 is cleverly installed at the upper end edge of the tooling base plate 1 through the mounting bracket 2, which is simple and practical in design. The rotary handle 3 inside adopts T-shaped key and T-shaped slot structure, which is closely connected with the abutting block 4. When adjusting the bearing bush position, you only need to rotate the rotary handle 3 slightly, and through the principle of mechanical transmission, the abutting block 4 can be pushed to move along the preset track to the double-end surface grinding machine end opening, realizing the accurate positioning of the bearing bush.

[0030] The two ends of the tooling base plate 1 are cleverly provided with notches 6, which are designed for the splicing plate 7. The splicing plate 7 adopts "convex" shape design, which perfectly matches the shape of the notch 6, ensuring the stability of splicing. The tail wing of the splicing plate 7 is provided with a pin hole 8, and the inner wall of the notch 6 is provided with a corresponding butt joint hole 9. By inserting the bolt into the pin hole 8 and the butt joint hole 9, the splicing plate 7 and the tooling base plate 1 are firmly connected.

[0031] At the upper end of the splicing plate 7, a T-shaped sliding groove 10 is innovatively designed, which provides infinite possibilities for subsequent bearing bush positioning. A T-shaped sliding block 11 can be inserted into the T-shaped sliding groove 10, and a screw rod 12 is provided on the sliding block. An oval positioning block 13 is sleeved on the screw rod 12. By adjusting the position of the screw rod 12, the distance between the oval positioning block 13 and the abutting block 4 can be flexibly changed, thereby forming a triangular positioning and clamping of the bearing bush. This design not only improves the positioning accuracy and stability, but also greatly enhances the adaptability and flexibility of the tooling.

[0032] In order to further improve the positioning effect and protect the surface of the bearing bush from damage, a buffer pad 14 is specially provided at the lower end of the oval positioning block 13. The buffer pad 14 is made of high elasticity and high wear-resistant material, and is firmly fixed on the positioning block by adhesive. During processing, the buffer pad 14 can effectively absorb vibration and impact force, protecting the surface of the bearing bush from scratches or indentation. In addition, the upper end surface of the oval positioning block 13 is also carefully designed with anti-slip texture, further improving the stability of the bearing bush during positioning.

[0033] This splicing type double-end surface grinding machine positioning tool has shown many advantages in practical application. First, its modular design allows the tooling to be quickly assembled and disassembled, greatly saving time and cost of replacing tooling. Second, the high-precision positioning and clamping mechanism ensures the stability of the bearing bush during processing, improving processing precision and efficiency. In addition, the tooling also has good adaptability and flexibility, which can meet the processing needs of different specifications and shapes of bearing bushes. Finally, the buffer pad 14 and anti-slip texture and other detailed design further improve the practicality and protection performance of the tooling.

[0034] In summary, this splicing type double-end surface grinding machine positioning tool, with its unique design concept and excellent performance, stands out in the modern mechanical processing industry. It not only improves processing efficiency and precision, but also reduces production cost and labor intensity, injecting new power for the transformation and upgrading of manufacturing industry. With the continuous progress of technology and the continuous expansion of the market, it is believed that this tool will be widely used and promoted in more fields.

[0035] The assembling process of the positioning tool: place the tool base plate 1 on a stable workbench, and make sure that it does not shake. Through the installation hole 5, use bolts and other fasteners to fix the tool base plate 1 on the double-end surface grinding machine. Install the mounting frame 2 to the upper end edge of the tool base plate 1, and make sure that it is stable. Install the rotating handle 3 on the mounting frame 2, and make sure that the T-shaped key, T-shaped slot structure and the abutting block 4 are tightly connected. Align the "convex" part of the splicing plate 7 with the notch 6 of the tool base plate 1, and use bolts to firmly connect the splicing plate 7 to the tool base plate 1 through the pin hole 8 and the butt joint hole 9. Insert the T-shaped sliding block 11 into the T-shaped sliding slot 10, and install the screw rod 12 and the oval positioning block 13 on the sliding block. Paste the buffer pad 14 at the lower end of the oval positioning block 13, and make sure that the buffer pad 14 is firmly fixed.

[0036] The use process of the positioning tool: place the bearing bush to be polished on the tool base plate 1, and preliminarily align. Rotate the rotating handle 3, and push the abutting block 4 to move along the preset track to the double-end surface grinding machine end opening through the mechanical transmission principle. Adjust the screw rod 12 on the T-shaped sliding block 11, so that the oval positioning block 13 forms a triangular positioning clamping with the abutting block 4 and the bearing bush. After confirming that the bearing bush is stably clamped, start the double-end surface grinding machine to process the curved surface of the bearing bush. After the processing is completed, reverse rotate the rotating handle 3 to release the bearing bush, and take it down for the next process. If the bearing bush needs to be replaced or the tool needs to be adjusted, the above assembling and using processes can be repeated.
