Description

Technical Field

[0001] This utility model relates to a grinding device for pump body processing, belonging to the field of pump body processing technology. Background Technology

[0002] The pump body is the core pressure-bearing component of pump equipment, widely used in petrochemical, water conservancy projects, mining machinery, water supply and drainage systems and other fields. The smoothness of its inner wall, the flatness of its outer wall, and the precision of its sealing surface directly determine the pump's operating efficiency, pressure resistance and service life. In the traditional pump body processing process, after the pump body is formed by casting, forging or welding, there will be defects such as residual material from the riser and gating gate, welding spatter, casting sand holes, and machining tool marks on the surface. If these defects are not polished, they will lead to poor sealing during subsequent assembly, increased fluid resistance, and even failures such as component wear and leakage.

[0003] According to patent document CN217619683U, a grinding device for processing pump body cover is disclosed. It includes a grinding box, a support box fixedly installed on the lower outer wall of the grinding box, a first motor fixedly installed on the lower inner wall of the support box, a clamping device fixedly installed on the drive end of the first motor, and mounting holes provided on the lower wall of the grinding box. This invention uses the clamping device to clamp and fix the pump body cover of any size at three points along its inner diameter, thereby effectively fixing the pump body cover and preventing displacement during grinding. The device uses a lifting device to... The grinding disc is fed to the pump body cover, making it suitable for grinding the upper wall surface of pump body covers of any height. The second grinding disc is fed by the feeding device to grind the side wall surface of pump body covers of any size. The pump body cover can be ground on both the upper and side walls, eliminating the need for manual grinding and improving the efficiency of pump body cover grinding. Although it can also grind the upper and side surfaces of the pump body, in actual use, it can only grind the upper and side surfaces through the feeding device, but it cannot grind the included angle at the junction of the upper and side surfaces, resulting in low adaptability of the device.

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 1:

[0025] Please see Figures 1-4This utility model provides a technical solution: including a grinding device 1, which includes a conveying component 101, a first grinding component 102, a positioning bracket 103, and a second grinding component 2. A slider 208 is slidably connected to the inner surface of a slide rail 210. The slide rail 210 is connected to the output end of a servo motor 212 via a rotating shaft. A first knob 202 is fixedly installed at the upper end of a first threaded rod 203, which is driven by the first knob 202. A second knob 205 is fixedly installed at one end of a second threaded rod 206, which is driven by the second knob 205. The first threaded rod 203 has a two-section design, one section being cylindrical and the other being threaded. A grinding wheel 209 is located below a first motor 204 and is driven by the first motor 204. An adjusting disc 211 is located above the slide rail 210, and a hydraulic cylinder 201 is located above the positioning bracket 103.

[0026] Specifically, the operator places the pump body on the tray of the conveying assembly 101. The conveying assembly 101 then delivers the pump body to the area below the first grinding assembly 102. The first grinding assembly 102 grinds the upper surface of the pump body. After the upper surface of the pump body is ground, the conveying assembly 101 delivers the pump body to the area below the second grinding assembly 2. The operator then turns the second knob 205 according to the size and diameter of the pump body. The second knob 205 drives the second threaded rod 206 to control the slider 208. The slider 208 moves along the slide rail 210 to adjust the position of the grinding wheel 209. The operator then uses the first knob 202 to adjust the position of the grinding wheel 209. A knob 202 drives the first threaded rod 203 to adjust the tilt angle of the slide rail 210. The rotation radius of the mounting base is precisely matched with the length of the grinding wheel 209. After switching, the non-working grinding wheel deviates from the pump body centerline by ≥5cm to avoid collision and interference with the second grinding component 2. The repeatability of the X-axis and Y-axis electric slide rails is ±0.01mm, with an effective stroke of 50cm. The ball screw transmission reduces the running backlash to ensure accurate grinding trajectory. A miniature electric push rod is provided between the mounting plate and the mounting base, with a feed adjustment step of 0.005mm, which can adjust the grinding depth in real time according to the surface roughness of the pump body.

[0027] Example 2:

[0028] Please see Figures 2-3The difference between this embodiment and Embodiment 1 is that: the second grinding component 2 includes a hydraulic cylinder 201 for positioning transmission. A servo motor 212 is provided at the output end of the hydraulic cylinder 201. An adjustment plate 211 and a slide rail 210 are provided at the output end of the servo motor 212. The slide rail 210 is rotatably connected to the output end of the servo motor 212. A first threaded hole 213 is provided on the adjustment plate 211. A first threaded rod 203 is threadedly connected to the inner surface of the first threaded hole 213. A slot 214 is provided on the slide rail 210. A slider 208 is provided on the inner surface of the slide rail 210. A second threaded hole 207 is provided on the slider 208. A second threaded rod 206 is threadedly connected to the inner surface of the second threaded hole 207. A first motor 204 is fixedly provided on the upper surface of the slider 208. A grinding wheel 209 is fixedly provided at the output end of the first motor 204.

[0029] Specifically, the operator can use the hydraulic cylinder 201 to provide a wide range of positioning and transmission, the servo motor 212 to provide precise angular rotation, and the adjusting plate 211, the first threaded rod 203, the slide rail 210, the slider 208, and the second threaded rod 206 to form a precise grinding head position and attitude adjustment mechanism. The hydraulic cylinder 201 is responsible for overall coarse adjustment and positioning, the servo motor 212 is responsible for adjusting the rotation angle of the grinding head, the first threaded rod 203 and the adjusting plate 211 are responsible for the radial fine adjustment of the grinding head, and the second threaded rod 206 and the slider 208 are responsible for the axial fine adjustment of the grinding head. This multi-level, multi-degree-of-freedom adjustment capability allows the 209 grinding wheel to contact any area of ​​the pump body surface with extremely high precision and flexibility, achieving precise grinding of complex curved surfaces, internal structures, and various defects, thereby significantly improving the quality and efficiency of pump body processing. The three-jaw chuck has a clamping diameter range of 5-30cm and a clamping coaxiality tolerance of ≤0.02mm. Automatic clamping is achieved through hydraulic drive, and the clamping force is adjustable from 0-500N to adapt to different pump body specifications. The drive motor adopts a servo motor, which is driven by a gear set to the grinding wheel shaft with a transmission ratio of 1:2 to ensure stable grinding wheel speed.

[0030] Working principle and process: The operator places the pump body on the tray on the conveying assembly 101. The conveying assembly 101 delivers the pump body to the bottom of the first grinding assembly 102. The first grinding assembly 102 grinds the upper surface of the pump body. After the upper surface of the pump body is ground, the pump body is delivered to the bottom of the second grinding assembly 2 via the conveying assembly 101. Then, the operator turns the second knob 205 according to the size and diameter of the pump body. The second knob 205 drives the second threaded rod 206 to control the slider 208. The slider 208 moves along the slide rail 210 to adjust the position of the grinding wheel 209. The operator can adjust the tilt angle of the slide rail 210 by turning the first knob 202, which drives the first threaded rod 203. The operator can use the hydraulic cylinder 201 to provide a wide range of positioning transmission, and the servo motor 212 to provide precise angle rotation. The adjusting plate 211, the first threaded rod 203, the slide rail 210, the slider 208, and the second threaded rod 206 can form a precise grinding head position and posture adjustment mechanism. Hydraulic cylinder 201 is responsible for overall coarse adjustment and positioning, servo motor 212 is responsible for adjusting the rotation angle of the grinding head, first threaded rod 203 and adjusting disc 211 are responsible for radial fine adjustment of the grinding head, while second threaded rod 206 and slider 208 are responsible for axial fine adjustment of the grinding head. This multi-level, multi-degree-of-freedom adjustment capability allows the grinding wheel 209 to contact any area of ​​the pump body surface with extremely high precision and flexibility, achieving precise grinding of complex curved surfaces, internal structures, and various defects, thereby significantly improving the quality and efficiency of pump body processing.
