Description

Technical Field

[0001] This utility model belongs to the field of water pump housing processing technology, and in particular relates to a water pump housing processing tooling. Background Technology

[0002] The pump casing is an important component of a water pump. Its main function is to surround the pump impeller and form a gradually expanding water outlet channel. The pump casing is usually connected to the bracket of the centrifugal pump's mounting bearing and is encapsulated on the outside of the centrifugal pump body, serving a supporting and fixing function. In summary, the existing technology has the following problems: the pump casing needs to be processed by drilling, cutting, and grinding. When grinding the pump casing, appropriate grinding tools need to be selected, such as sandpaper, grinding machines, sandblasting equipment, etc. Manual grinding can more finely treat the surface of the pump casing. During grinding, the pump casing is usually placed directly on the grinding table without any restraint. During the grinding process, the pump casing is prone to shaking, which affects the grinding precision. Moreover, the position of the pump casing cannot be easily adjusted during grinding, reducing grinding efficiency. However, there is no tooling fixture for grinding the pump casing in a more convenient and stable manner. Therefore, a pump casing processing tooling is proposed to solve the above problems. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a tooling for processing water pump housings, which has the advantages of enabling more convenient and stable grinding of water pump housings. It solves the problem that existing water pump housings require drilling, cutting, and grinding, and that grinding requires the selection of appropriate grinding tools, such as sandpaper, grinding machines, and sandblasting equipment. Manual grinding can achieve more precise surface treatment of the water pump housing, but the water pump housing is usually placed directly on the grinding table without any positioning, which easily leads to shaking of the water pump housing during grinding, affecting the grinding precision. Furthermore, the position of the water pump housing cannot be easily adjusted during grinding, reducing grinding efficiency. However, existing tooling fixtures are not available for more convenient and stable grinding of water pump housings.

[0004] This utility model is implemented as follows: a water pump housing processing fixture includes a bottom support and two adjusting frames. The bottom of the adjusting frames is fixedly connected to the top of the bottom support. An adjusting rod is provided on the top of the bottom support, and the surface of the adjusting rod contacts the inner cavity of the adjusting frame. A top rotating shell is fixedly connected to the bottom of the adjusting rod. A top rotating rod is movably connected to the inner cavity of the top rotating shell. The bottom of the top rotating rod penetrates through the top rotating shell and extends to the outside of the inner cavity of the top rotating shell. A bottom rotating shell is fixedly connected to the top of the bottom support, and a bottom rotating rod is movably connected to the inner cavity of the bottom rotating shell. The top of the bottom rotating rod penetrates through the bottom rotating shell and extends to the outside of the inner cavity of the bottom rotating shell. A chuck is fixedly connected to the surface of the top rotating rod, and a turntable is fixedly connected to the surface of the bottom rotating rod. Two control blocks and two limiting devices are provided on the top of the adjusting rod.

[0005] In a preferred embodiment of this invention, the limiting device includes two limiting blocks. An outer shell is fixedly connected to the side of the limiting block near the adjusting frame. An inner shell is movably connected to the inner cavity of the outer shell. The surface of the inner shell is fixedly connected to the surface of the adjusting rod. A spring is fixedly connected to the side of the limiting block near the adjusting frame. The surface of the spring is fixedly connected to the surface of the adjusting rod. By setting the limiting device, when the adjusting rod, the top rotating shell, the top rotating rod, and the chuck move to a suitable position, the limiting device restricts the position of the adjusting rod, the top rotating shell, the top rotating rod, and the chuck.

[0006] As a preferred embodiment of this utility model, the surface of the limiting block is provided with extrusion holes, and the top of the adjusting rod is movably connected to four extrusion shells that cooperate with the extrusion holes via a rotating shaft. The surface of the extrusion shell is movably connected to the inner cavity of the extrusion hole. By setting the extrusion holes and extrusion shells, when the extrusion shells rotate via the rotating shaft, they can generate extrusion force on the extrusion holes. The extrusion holes subjected to extrusion force can drive the limiting block to move.

[0007] As a preferred embodiment of this utility model, an extrusion column is fixedly connected to the inner cavity of the extrusion shell, and an extrusion inclined plate that cooperates with the extrusion column is fixedly connected to the opposite sides of the two control blocks. The surface of the extrusion inclined plate is in contact with the surface of the extrusion column. By setting the extrusion column and the extrusion inclined plate, when the control block moves, it will drive the extrusion inclined plate to move along the surface of the extrusion column. The extrusion inclined plate can generate extrusion force on the extrusion column, and the extrusion column subjected to extrusion force will move away from the control block.

[0008] As a preferred embodiment of this utility model, the surface of the control block is provided with a stabilizing hole, and the top of the adjusting rod is fixedly connected with two stabilizing blocks that cooperate with the stabilizing hole. The surface of the stabilizing block is movably connected to the inner cavity of the stabilizing hole. By setting the stabilizing hole and the stabilizing block, when the control block moves, it will drive the stabilizing hole to move along the surface of the stabilizing block. The cooperation of the stabilizing hole and the stabilizing block has a limiting effect on the movement position of the control block.

[0009] As a preferred embodiment of this utility model, each of the two adjusting frames has a limiting groove on its opposite side that cooperates with the limiting block. The surface of the limiting block contacts the inner cavity of the limiting groove. There are several limiting grooves that are evenly distributed on the opposite side of the two adjusting frames. By setting the limiting grooves, when the adjusting rod moves to the appropriate position and the control block is released, the restoring force generated by the spring returning to its shape will drive the limiting block to be locked into the inner cavity of the limiting groove. The cooperation between the limiting block and the limiting groove has a limiting effect on the position of the adjusting rod.

[0010] As a preferred embodiment of this utility model, two sliders are fixedly connected to the front and rear sides of the adjusting rod. The side of the slider away from the adjusting frame passes through the adjusting frame and extends to the outer side of the inner cavity of the adjusting frame. By setting the slider, when the adjusting rod moves, it will drive the slider to move along the inner cavity of the adjusting frame. The setting of the slider has a limiting effect on the movement position of the adjusting rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model solves the problem of existing water pump housings requiring drilling, cutting, and grinding by using a limiting device, limiting block, outer shell, inner shell, and spring in combination. When grinding the water pump housing, it is necessary to select appropriate grinding tools, such as sandpaper, grinding machine, sandblasting equipment, etc. Manual grinding can more finely process the surface of the water pump housing. During grinding, the water pump housing is usually placed directly on the grinding table without limiting, which easily causes the water pump housing to shake during the grinding process, affecting the grinding precision. Moreover, the position of the water pump housing cannot be easily adjusted during grinding, reducing grinding efficiency. However, existing water pump housings do not have tooling fixtures that can perform more convenient and stable grinding processing.

[0013] 2. By setting a limiting device, the extrusion hole subjected to the extrusion pressure will drive the limiting block to move away from the adjustment frame. When the limiting block moves, it will drive the outer shell to move along the surface of the inner shell. When the limiting block moves, the force generated will cause the spring to undergo elastic deformation. The restoring force generated by the spring returning to its shape will drive the limiting block to be stuck in the inner cavity of the limiting groove. The limiting device has a limiting effect on the position of the adjustment rod, the top rotating shell, the top rotating rod and the chuck. Attached Figure Description

[0020] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 5 As shown in the figure, a water pump housing processing fixture provided by this utility model includes a bottom support 1 and two adjusting frames 2. The bottom of the adjusting frame 2 is fixedly connected to the top of the bottom support 1. An adjusting rod 3 is provided on the top of the bottom support 1. The surface of the adjusting rod 3 contacts the inner cavity of the adjusting frame 2. A top rotating shell 4 is fixedly connected to the bottom of the adjusting rod 3. A top rotating rod 5 is movably connected to the inner cavity of the top rotating shell 4. The bottom of the top rotating rod 5 passes through the top rotating shell 4 and extends to the outside of the inner cavity of the top rotating shell 4. A bottom rotating shell 6 is fixedly connected to the top of the bottom support 1. A bottom rotating rod 7 is movably connected to the inner cavity of the bottom rotating shell 6. The top of the bottom rotating rod 7 passes through the bottom rotating shell 6 and extends to the outside of the inner cavity of the bottom rotating shell 6. A chuck 8 is fixedly connected to the surface of the top rotating rod 5. A turntable 9 is fixedly connected to the surface of the bottom rotating rod 7. Two control blocks 10 are provided on the top of the adjusting rod 3. Two limiting devices 11 are provided on the top of the adjusting rod 3.

[0023] refer to Figure 5 The limiting device 11 includes two limiting blocks 1101. An outer shell 1102 is fixedly connected to the side of the limiting block 1101 near the adjusting frame 2. An inner shell 1103 is movably connected to the inner cavity of the outer shell 1102. The surface of the inner shell 1103 is fixedly connected to the surface of the adjusting rod 3. A spring 1104 is fixedly connected to the side of the limiting block 1101 near the adjusting frame 2. The surface of the spring 1104 is fixedly connected to the surface of the adjusting rod 3.

[0024] The above solution is adopted: by setting a limiting device 11, when the adjusting rod 3, the top rotating shell 4, the top rotating rod 5 and the chuck 8 move to the appropriate position, the limiting device 11 has a limiting effect on the position of the adjusting rod 3, the top rotating shell 4, the top rotating rod 5 and the chuck 8.

[0025] refer to Figure 5 The surface of the limiting block 1101 is provided with extrusion holes 12. The top of the adjusting rod 3 is movably connected to four extrusion shells 13 that cooperate with the extrusion holes 12 via a rotating shaft. The surface of the extrusion shell 13 is movably connected to the inner cavity of the extrusion hole 12.

[0026] The above solution is adopted: by setting the extrusion hole 12 and the extrusion shell 13, when the extrusion shell 13 rotates through the rotating shaft, it can generate extrusion force on the extrusion hole 12, and the extrusion hole 12 subjected to extrusion force can drive the limit block 1101 to move.

[0027] refer to Figure 5 An extrusion column 14 is fixedly connected to the inner cavity of the extrusion shell 13. An extrusion inclined plate 15 that works with the extrusion column 14 is fixedly connected to the opposite side of the two control blocks 10. The surface of the extrusion inclined plate 15 is in contact with the surface of the extrusion column 14.

[0028] The above scheme is adopted: by setting the extrusion column 14 and the extrusion inclined plate 15, when the control block 10 moves, it will drive the extrusion inclined plate 15 to move along the surface of the extrusion column 14. The extrusion inclined plate 15 can generate extrusion force on the extrusion column 14, and the extrusion column 14 subjected to extrusion force will move away from the control block 10.

[0029] refer to Figure 5 The surface of the control block 10 is provided with a stabilizing hole 16. The top of the adjusting rod 3 is fixedly connected with two stabilizing blocks 17 that cooperate with the stabilizing hole 16. The surface of the stabilizing block 17 is movably connected to the inner cavity of the stabilizing hole 16.

[0030] The above solution is adopted: by setting a stabilizing hole 16 and a stabilizing block 17, when the control block 10 moves, it will drive the stabilizing hole 16 to move along the surface of the stabilizing block 17. The cooperation of the stabilizing hole 16 and the stabilizing block 17 has a limiting effect on the movement position of the control block 10.

[0031] refer to Figure 2 Each of the two adjustment frames 2 has a limiting groove 18 on one side opposite to the limiting block 1101. The surface of the limiting block 1101 contacts the inner cavity of the limiting groove 18. There are several limiting grooves 18, which are evenly distributed on one side opposite to the two adjustment frames 2.

[0032] The above solution is adopted: by setting the limiting groove 18, when the adjusting rod 3 moves to the appropriate position, the control block 10 is released, and the restoring force generated by the spring 1104 returning to its shape will drive the limiting block 1101 to be inserted into the inner cavity of the limiting groove 18. The cooperation between the limiting block 1101 and the limiting groove 18 has a limiting effect on the position of the adjusting rod 3.

[0033] refer to Figure 4 Two sliders 19 are fixedly connected to the front and rear sides of the adjusting rod 3. The side of the slider 19 away from the adjusting frame 2 passes through the adjusting frame 2 and extends to the outside of the inner cavity of the adjusting frame 2.

[0034] The above solution is adopted: by setting slider 19, when the adjusting rod 3 moves, it will drive slider 19 to move along the inner cavity of adjusting frame 2. The setting of slider 19 has a limiting effect on the movement position of adjusting rod 3.

[0035] The working principle of this utility model:

[0036] When the pump housing needs more convenient and stable grinding, the operator first places the pump housing on the turntable 9, and then pulls the control blocks 10 to opposite sides. As the control blocks 10 move, the stabilizing hole 16 moves along the surface of the stabilizing block 17. The movement of the control blocks 10 also moves the extrusion inclined plate 15 along the surface of the extrusion column 14. The extrusion column 14, under pressure, moves to the opposite side. The movement of the extrusion column 14 causes the extrusion shell 13 to rotate along the inner cavity of the extrusion hole 12 via the rotating shaft. The extrusion hole 12, under pressure, causes the limiting block 1101 to move away from the adjusting frame 2. The movement of the limiting block 1101 causes the outer shell 1102 to move along the surface of the inner shell 1103. The force generated by the movement of the limiting block 1101 causes the spring 1104 to elastically deform. When the limiting block 1101 disengages from the inner cavity of the limiting groove 18, it moves closer to the pump housing. The adjustment rod 3 moves to one side. When the adjustment rod 3 moves, it will drive the slider 19 to move along the inner cavity of the adjustment frame 2. When the adjustment rod 3 moves, it will drive the top rotating shell 4, the top rotating rod 5 and the chuck 8 to move closer to the water pump housing. When the top rotating rod 5 moves to the inner cavity of the water pump housing, and at the same time the surface of the chuck 8 contacts the inner cavity of the bottom rotating rod 7, the two control blocks 10 are released. The restoring force generated by the spring 1104 returning to its shape will drive the limiting block 1101 to be inserted into the inner cavity of the limiting groove 18. The cooperation of the limiting block 1101 and the limiting groove 18 has a limiting effect on the position of the adjustment rod 3, the top rotating shell 4, the top rotating rod 5 and the chuck 8. The cooperation of the chuck 8 and the turntable 9 has a limiting effect on the position of the water pump housing. The water pump housing can be rotated during grinding. When the water pump housing rotates, it can drive the top rotating rod 5 to rotate along the inner cavity of the top rotating shell 4, and at the same time drive the bottom rotating rod 7 to rotate along the inner cavity of the bottom rotating shell 6. At this time, the water pump housing can be ground more conveniently and stably.

[0037] In summary, this water pump housing machining fixture, through the coordinated use of the limiting device 11, the limiting block 1101, the outer shell 1102, the inner shell 1103, and the spring 1104, solves the problem that existing water pump housings require drilling, cutting, and grinding. Grinding the water pump housing requires selecting appropriate grinding tools, such as sandpaper, a grinding machine, or sandblasting equipment. Manual grinding allows for more precise surface treatment of the water pump housing. However, grinding typically involves placing the water pump housing directly on the grinding table without limiting it, which can easily cause the water pump housing to wobble, affecting the grinding precision. Furthermore, the position of the water pump housing cannot be easily adjusted during grinding, reducing grinding efficiency. Currently, there is no fixture or jig for more convenient and stable grinding of water pump housings.
