Description

Technical Field

[0001] This utility model relates to the field of water pump rear cover processing technology, and in particular to a water pump rear cover sealing surface processing and fixing device. Background Technology

[0002] The rear cover of a water pump is one of its key components, and its rear end face (or flange end face) typically has an annular sealing surface (or sealing ring). This sealing surface is used to install gaskets or to directly fit against the pump body, and its machining quality (such as flatness, roughness, and perpendicularity / coaxiality with the center hole) directly affects the pump's sealing performance and operating efficiency. Poor sealing can lead to liquid leakage, reduced pump efficiency, and even malfunctions. Therefore, ensuring high precision in the machining of the sealing surface is crucial.

[0003] Currently, the processing of the sealing surface of the water pump back cover (including the end face that mates with the pump body, the mechanical stationary ring mounting surface, etc.) requires clamping and fixing with a fixing device before the sealing surface can be processed. When the product model is changed (such as changes in flange diameter, center hole diameter, height, etc.), the existing fixing device often cannot be quickly adjusted or adapted, requiring the replacement of the entire set of fixtures or complex modifications, which increases costs and changeover time. Utility Model Content

[0018] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0019] Please see Figure 1-9 The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figure 1-5As shown, a water pump rear cover sealing surface processing and fixing device includes a water pump rear cover body 1 and a support plate 4. A support mechanism 2 is fixedly installed on the upper surface of the support plate 4. The support mechanism 2 includes a support ring 21 and a placement plate 22. The placement plate 22 is fixed in the middle of the support ring 21. The surface of the support ring 21 has several fan-shaped through grooves 211 arranged in a circular pattern. A fixing mechanism 3 for clamping the water pump rear cover body 1 is provided in the fan-shaped through grooves 211. After the water pump rear cover body 1 is placed on the placement plate 22, the position of the water pump rear cover body 1 is fixed by the fixing mechanism 3. The fixing mechanism 3 includes a locking component 31, a support frame 32, a height adjustment component 33, and a clamping component 34 arranged sequentially from bottom to top. The locking component 31 locks the position of the clamping component 34, and the height adjustment component 33 adjusts the height of the clamping component 34, so that the clamping component 34 can better clamp and fix the water pump back cover body 1 of different sizes.

[0020] like Figure 1 As shown in the figure, in this embodiment, a plurality of support rods 41 are fixedly provided on the lower surface of the support plate 4.

[0021] like Figure 2-3 As shown, in this embodiment, a toothed ring 23 is fixedly provided on the circumferential surface of the placement plate 22, and the lower surface of the toothed ring 23 is in contact with the upper surface of the support plate 4.

[0022] like Figure 2 As shown, in this embodiment, the outer circumferential surface of the support ring 21 is provided with an arc-shaped through groove 212 corresponding to the fan-shaped through groove 211, and the arc-shaped through groove 212 communicates with the fan-shaped through groove 211.

[0023] like Figure 5-8 As shown, in this embodiment, the locking component 31 includes an arc-shaped block 311, a toothed block 314, and a pull rod 313. The size of the arc-shaped block 311 is adapted to the fan-shaped through groove 211, and the arc-shaped block 311 slides in the fan-shaped through groove 211. The lower end face of the arc-shaped block 311 is provided with a groove 316, the toothed block 314 is slidably disposed in the groove 316, the side of the toothed block 314 is fixedly connected to the inner wall of the groove 316 with a spring 315, and the toothed block 314 is adapted to the tooth groove of the toothed ring 23. The lower end face of the toothed block 314 is provided with a snap-fit ​​groove 3141, one end of the pull rod 313 is rotatably engaged with the snap-fit ​​groove 3141, and the spring 315 is sleeved on the outside of the pull rod 313. The pull rod 313 has a threaded groove on its circumferential surface within the slide groove 316, and the arc surface of the arc block 311 has a threaded hole 312. The threaded groove of the pull rod 313 mates with the threaded hole 312. The pull rod 313 is slidably disposed in the arc-shaped through groove 212 near the outer circumferential surface.

[0024] After pulling the lever 313, the toothed block 314 retracts into the groove 316, and the spring 315 is compressed. Then, the lever 313 is rotated so that the threaded groove of the lever 313 engages with the threaded hole 312 of the arc-shaped block 311 to prevent the spring 315 from retracting. Then, the arc-shaped block 311 can be slid to adjust its position in the fan-shaped through groove 211. After adjustment, the lever 313 is rotated in the opposite direction, and then the spring 315 resets the toothed block 314 so that the toothed block 314 engages with the toothed groove of the toothed ring 23. At this time, the position of the arc-shaped block 311 is fixed again.

[0025] like Figure 5-9 As shown, in this embodiment, the connecting frame 32 is fixedly mounted on the upper end face of the arc-shaped block 311.

[0026] like Figure 5-9 As shown, in this embodiment, the height adjustment component 33 includes a support frame 331 and a connecting plate 334. The support plate 4 is fixedly installed on the upper surface of the connecting frame 32. Two sets of connecting rods 333 are symmetrically arranged between the support frame 331 and the connecting plate 334, and the two adjacent connecting rods 333 are hinged together. A bidirectional screw 335 is rotatably installed inside the support frame 331. A slider 336 is symmetrically threaded on the surface of the bidirectional screw 335. Guide shafts that rotate with the connecting rod 333 are symmetrically fixed on both sides of the slider 336. The support frame 331 has symmetrical guide grooves 332 on both sides, and the guide shaft is slidably disposed in the guide grooves 332; The lower surface of the connecting plate 334 is provided with a set of hinge seat 1 3342 and a set of hinge seat 2 3343. Both hinge seat 1 3342 and hinge seat 2 3343 are hinged to the corresponding connecting rod 333. Hinge seat 1 3342 is fixed to the connecting plate 334. The lower surface of the connecting rod 333 plate is symmetrically provided with sliding grooves 3341. Hinge seat 2 3343 is slidably disposed in the sliding grooves 3341. By rotating the bidirectional screw 335, the slider 336 drives the connecting rods 333 on both sides to move, thereby adjusting the height of the connecting plate 334.

[0027] like Figure 6 As shown, in this embodiment, the clamping assembly 34 includes a fixed base 341 and a clamping screw 342. The fixed base 341 is fixedly disposed on the upper surface of the connecting plate 334. The clamping screw 342 passes through the fixed base 341 and is threaded. A top head 343 is fixedly disposed on the outer end of the clamping screw 342. By tightening the clamping screw 342, the top head 343 is pressed against the side of the water pump rear cover body 1. Together with the top heads 343 in other positions, the water pump rear cover body 1 is fixed, which improves the stability of the sealing surface of the water pump rear cover body 1 during subsequent processing.

[0028] Specifically, after placing the water pump rear cover body 1 on the placement plate 22, adjust the position of the arc block 311, and then adjust the height of the connecting plate 334 so that the orientation and position of the top head 343 correspond to the side of the water pump rear cover body 1 that can be clamped. Then rotate the clamping screw 342 so that the top head 343 completes the clamping and fixing of the water pump rear cover body 1. This can effectively clamp water pump rear cover bodies 1 of different sizes and specifications, effectively improving the applicability of this device.
