Description

Technical Field

[0001] This utility model relates to the field of water pump processing fixture technology, specifically a water pump body processing fixture. Background Technology

[0002] A water pump is a machine that transports or pressurizes liquids. It transfers the mechanical energy of a prime mover or other external energy to the liquid, increasing the liquid's energy. It is mainly used to transport liquids including water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals. After the water pump casing is cast, it needs to be clamped and fixed with a fixture in order to process its outlet and other parts.

[0003] Existing pump body machining fixtures, such as the pump housing machining fixture disclosed in publication number CN219465432U, can clamp and fix irregularly shaped pump housings from any angle. However, this fixture uses a spring-pressed connecting rod for clamping and fixing. Because the spring has elastic stroke, it suffers from poor stability during pump housing machining. At the same time, because the pump housing is heavy, it is inconvenient to place it before clamping. Therefore, we propose a pump body machining fixture. Utility Model Content

It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] The following describes, with reference to the accompanying drawings, some embodiments of a water pump body machining fixture provided by this utility model. Example

[0026] Combination Figure 1-5 As shown, the present invention provides a water pump body processing fixture, comprising: a worktable 100 and a clamping assembly 200; the worktable 100 includes fixed feet 101 arranged and fixedly installed on both sides of its bottom; the clamping assembly 200 includes a lower rubber pad 201 fixedly installed on the upper end of the worktable 100, an upper pressure plate 202 movably installed on the upper part of the lower rubber pad 201, an upper rubber pad 203 fixedly installed on the bottom of the upper pressure plate 202, a double-headed cylinder 204 fixedly installed at the center of the upper end of the upper pressure plate 202, clamping plates 205 fixedly installed at both ends of the double-headed cylinder 204, rubber blocks 206 fixedly installed at the lower outer ends of the clamping plates 205, rollers 207 movably arranged on both sides of the worktable 100, and a pump casing 208 movably placed on the upper end of the lower rubber pad 201. The middle of the platform 100 is also provided with a slot 209. The outer ends of the rollers 207 are also fixedly installed with protective sleeves 210. The upper end of the upper pressure plate 202 is also fixedly installed with a fixed seat 211. The top of the fixed seat 211 is also fixedly installed with a lifting cylinder 212. The outer end of the lifting cylinder 212 is also fixedly installed with a fixed arm 213, and the bottom of the fixed arm 213 is fixed to the worktable 100. The upper pressure plate 202 is also provided with sliding grooves 214 on both sides, and the clamping plates 205 are movably installed in the sliding grooves 214. The middle of the upper pressure plate 202 is also fixedly installed with a restraining rod 215. The clamping plates 205 are also provided with restraining holes 216, and the restraining holes 216 and restraining rods 215 are matched. The lower rubber pad 201, the upper rubber pad 203 and the rubber block 206 are all soft rubber.

[0027] Specifically, a water pump is a machine that transports or pressurizes liquids. After the pump casing is cast, it needs to be clamped and fixed using a fixture for machining its outlet and other parts. The pump casing 208, placed on the upper end of the lower rubber pad 201 in this workbench 100, can be pressed between the upper pressure plate 202 and the workbench 100 by the lifting cylinder 212 at the top. The pump casing 208 is pressed tightly against the lower rubber pad 201 and the upper rubber pad 203, and the clamping plates 205 in the upper pressure plate 202 that support the two ends of the pump casing 208 together press and bind the entire pump casing 208 to ensure its stability during machining. The slot 209 in the middle of the workbench 100 and the telescopic adjustable clamping plate in the upper pressure plate 202 further enhance its stability. The plate 205 allows the fixture to clamp and fix pump housings 208 of different sizes. Meanwhile, the rollers 207 arranged on both sides of the workbench 100, and the protective sleeves 210 on the outer ends of the rollers 207, facilitate the disassembly and relocation of the pump housing 208 before and after processing, and also protect the outer end face of the pump housing 208 when it moves. The soft rubber block 206 on the outer end of the clamping plate 205 deforms and fits tightly when pressing the inner ends of the pump housing 208 to ensure stability in the clamping. The sliding grooves 214 on both sides of the upper pressure plate 202 are mainly used to restrain the movement of the clamping plates 205 on both sides. The restraint rods 215 movably installed in the clamping plate 205 mainly maintain the support of the clamping plate 205 in the clamping to ensure its stability.

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

[0029] When clamping and fixing pump housings 208 of different sizes, they are first placed on the upper end of roller 207 on one side of workbench 100, and then moved lightly along roller 207 to the middle of lower rubber pad 201. After the pump housing 208 is moved to the middle of lower rubber pad 201, the lifting cylinder 212 is activated to move the upper pressure plate 202 downward. When the clamping plates 205 on both sides of the bottom of the upper pressure plate 202 are on the inner end of the pump housing 208, the downward movement of the lifting cylinder 212 is paused and the double-headed cylinder 204 at the upper end of the upper pressure plate 202 is activated, so that the clamping plates 205 driven by its two ends can preload the two sides of the inner end of the pump housing 208. The pump housing 208 is adjusted and positioned using a clamping device. After the pump housing 208 is adjusted and positioned, the lifting cylinder 212 is activated to continue moving the upper pressure plate 202 downward, so as to firmly press the upper pressure plate 202 onto the upper part of the pump housing 208. Then, the upper and lower rubber pads 201 of the worktable 100 and the upper rubber pad 203 at the bottom of the upper pressure plate 202 are used to firmly press the pump housing 208 against the outer wall of the pump housing 208, thereby enhancing its stability during pressing. At the same time, the double-headed cylinder 204 is activated to stably clamp the inner end of the pump housing 208 through the clamping plates 205 at both ends, so as to ensure its stability during processing.

[0030] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
