Description

Technical Field

[0001] This utility model relates to the field of pump cover processing technology, specifically a fixed tooling for double-sided grinding of pump covers. Background Technology

[0002] Since both surfaces of the pump cover come into direct contact with other components, high-precision fitting and sealing performance are required, making double-sided grinding necessary. This ensures that both contact surfaces achieve the required smoothness and precision, thereby improving the overall performance and durability of the pump.

[0003] In existing technology, when grinding pump cover parts, a positioning hole is drilled in a fixed plate, and the pump cover is ground on both sides by grinding discs on the upper and lower sides. Although the device can complete the grinding of the pump cover on both sides, during the grinding process, simply placing the pump cover in the positioning hole without further stabilization is not performed. The diameter of the positioning hole is slightly larger than the pump cover for easy insertion, resulting in some movement space of the pump cover itself during subsequent grinding. First, the pump cover may experience slight displacement during grinding, leading to uneven grinding or low precision. Second, the movement space of the pump cover can also cause uneven edge wear or an uneven surface, thus affecting the final sealing performance and fitting accuracy. Therefore, we propose a fixed fixture for grinding pump covers on both sides to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Figures 1-6 As shown, this utility model provides a fixing fixture for double-sided grinding of a pump cover, including a lower grinding table 1, an upper grinding table 101 on the top of the lower grinding table 1 for double-sided grinding of the pump cover, a driving assembly 2 in the middle of the lower grinding table 1, and multiple positioning assemblies 3 for fixing the pump cover mounted on the table surface of the lower grinding table 1. Multiple evenly distributed grinding discs 102 are mounted on the end faces of the lower grinding table 1 and the upper grinding table 101 that are close to each other. The driving assembly 2 includes a driving disc 201, the lower grinding table 1 is fitted onto the surface of the driving disc 201, the driving disc 201 is rotatably connected to the lower grinding table 1, and multiple driving rods 202 and multiple push rods 308 are fixedly connected to the outer ring of the top of the driving disc 201. Multiple connecting rings 203 are evenly distributed around the axis of the drive disk 201. The connecting rings 203 are sleeved on the surface of the positioning component 3. The outer ring wall of the connecting ring 203 has multiple connecting grooves 204 that match the drive rod 202. The connecting ring 203 is engaged with the drive disk 201 through the connecting grooves 204. The drive disk 201 drives the fixed disk of the fixed pump cover to rotate. The lower grinding table 1 and the upper grinding table 101 rotate under the drive of the external drive component, so that the fixed disk will also rotate when the grinding tables 102 on both sides rotate, resulting in better and faster grinding effect on the pump cover.

[0025] Furthermore, the positioning component 3 includes multiple fixed platforms 301, with multiple connecting rings 203 sleeved on the surfaces of the fixed platforms 301. Each fixed platform 301 has multiple through-hole positioning windows 302 evenly distributed around its axis. The bottom of the fixed platform 301 is slidably connected to the surface of the lower grinding disc 102. Multiple fixed semi-rings 303 are fixedly connected to the top of the fixed platform 301, each positioned on one side of a positioning window 302. A fixed roller 304 and a fixed ring are also fixedly connected to the top of the fixed platform 301. 305. A fixed ring 305 is sleeved on the surface of a fixed roller 304 but does not contact it. A rotating ring 306 is built into the fixed ring 305. The outer ring wall of the rotating ring 306 is slidably connected to the inner wall of the fixed ring 305. The bottom of the rotating ring 306 contacts and is slidably connected to the fixed strip. The axes of the rotating ring 306, the fixed ring 305, the fixed roller 304, and the fixed platform 301 are coincident. A coil spring 307 is built into the rotating ring 306. The coil spring 307 is sleeved on the surface of the fixed roller 304. One end of the coil spring 307 is fixedly connected to the inner wall of the rotating ring 306, and the other end of the coil spring 307 is fixedly connected to the surface of the fixed roller 304. Multiple push rods 308 are fixedly connected to the outer ring wall of the 06 rotating ring 306. These push rods 308 are evenly distributed around the axis of the rotating ring 306. A moving half-ring 309 is fixedly connected to the end of each push rod 308 away from the rotating ring 306. The moving half-ring 309 is positioned on the side of the positioning window 302 away from the fixed half-ring 303. The moving half-ring 309 and the fixed half-ring 303 together form the fixing component of the pump cover. An inclined surface 310 is provided on the inner ring wall of the top of the moving half-ring 309 to facilitate the entry of the pump cover. A closed disc 311 is fixedly connected to the top of the fixed roller 304. Multiple feeding windows 312 are provided on the top of the closed disc 311 to facilitate the entry of the pump cover. The pump cover is placed in the positioning window 302 of the fixed plate. The inclined surface 310 on the top side of the moving half ring 309 facilitates the pump cover to push itself open and enter the positioning window 302. After entering, the moving half ring 309 will be pressed tightly against the pump cover by the elastic force of the push rod 308 at the tail and the coil spring 307. This allows the moving half ring 309 to work with the fixed half ring 303 to fix the pump cover. In the subsequent grinding process, the pump cover is more stable and will not shift, which improves the grinding accuracy. Moreover, the positioning part without ore will not cause wear on the edge of the pump cover, thus improving the sealing performance and fitting accuracy of the pump cover.

[0026] Working Principle: When using this device, the lower grinding table 1 provides a basic platform and is equipped with multiple positioning components 3 for fixing the pump cover. The lower grinding table 1 is also equipped with a drive component 2 to drive the grinding disc 102 to rotate. The upper grinding table 101 is connected to the lower grinding table 1 and is responsible for grinding the other side of the pump cover. The drive component 2 includes a drive disc 201, which drives the fixing disc that fixes the pump cover to rotate by rotating, thereby achieving uniform grinding. The positioning component 3 includes a fixing table 301 and a connecting ring 203. The positioning component 3 fixes the pump cover in the positioning window 302 through components such as a push rod 308, a fixing roller 304, a fixing ring 305, and a rotating ring 306. When the pump cover is placed into the positioning window 302, the inclined surface 310 of the moving semi-ring 309 helps the pump cover enter the positioning position. The moving half-ring 309 is pressed tightly against the pump cover under the action of the coil spring 307, while the fixed half-ring 303 clamps the pump cover, thereby ensuring that the pump cover does not shift during the grinding process. The lower grinding table 1 and the upper grinding table 101 are rotated by an external drive device, so that the fixed plate can also maintain its own rotation during the double-sided grinding process. This setting ensures the uniformity of the pump cover during double-sided grinding.

[0027] Through components such as the fixed table 301, fixed roller 304, and fixed ring 305, the pump cover can be stably fixed within the positioning window 302 during the grinding process, preventing displacement of the pump cover and improving grinding accuracy. The drive disc 201 drives the fixed disc to rotate, ensuring the uniformity of grinding and thus improving the surface quality of the pump cover. Through the cooperation of the upper and lower grinding tables, both sides of the pump cover can be ground simultaneously, shortening grinding time and improving work efficiency. The positioning component 3 avoids additional wear on the edge of the pump cover through a precise positioning and fixing mechanism, maintaining the sealing performance and fitting accuracy of the pump cover. The positioning component without ore quantity uses a positioning component that will not cause additional wear, which helps to maintain the integrity and performance of the pump cover. The design of the inclined surface 310 and the feed window 312 makes the placement and positioning of the pump cover easier and reduces the difficulty of operation. The fixed tooling for double-sided grinding of the pump cover not only improves the grinding accuracy and efficiency, but also reduces the wear of the pump cover through a fine fixing mechanism, thus improving production quality.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
