Description

Technical Field

[0001] This utility model belongs to the field of valve and pump housing processing, and more specifically, it relates to a high-precision positioning and clamping device for valve and pump housing processing. Background Technology

[0002] Valve and pump casing machining is a process involving casting, heat treatment, and mechanical structure machining of valve and pump casings. The basic shape of the casing is formed through casting, followed by heat treatment to improve its mechanical properties and wear resistance. Finally, the dimensions and shape of the valve body are precisely controlled through machining. Currently, in the mechanical structure machining of valve and pump casings, the casing is typically fixed to a fixture, and then the shape is machined using cutting tools mounted on a CNC lathe or machining center. However, when clamping the valve and pump casing on the fixture, multiple sets of clamping blocks need to be moved individually to press and adhere to the surface of the casing structure, and then the positions of the different clamping blocks are fixed. Therefore, traditional valve and pump casing clamping equipment requires the individual operation of multiple sets of clamping blocks to hold the casing. The clamping blocks cannot move synchronously according to the structure of the casing, making the clamping, installation, and disassembly of each set of casings cumbersome and complex. This significantly reduces the speed of assembly and disassembly on the fixture during the production of multiple sets of valve and pump casings, affecting the machining efficiency.

[0036] In this embodiment, the bottom end of the clamping plate 701 is provided with a cuboid protrusion. The front side of the cuboid protrusion of the clamping plate 701 is provided with a threaded through hole near the top. The threaded adjusting rod 702 is engaged in the threaded through hole of the cuboid protrusion of the clamping plate 701. During the process of the adjusting knob 703 driving the threaded adjusting rod 702 to rotate, the clamping plate 701 moves back and forth along the long groove of the support shell 706. The clamping position of the clamping plate 701 is adjusted according to the design parameters of different pump shell sizes and structures.

[0037] In this embodiment, there are six sets of support shells 706. Each set of support shells 706 has a long groove on its upper side.

The oblique through slots are arranged in a ring array around the vertical central axis of the push plate 9. The cylindrical protruding column structure on the lower side of the moving plate 704 is inserted into the oblique through slot of the push plate 9. The upper side of the ring plate structure at the bottom of the cylindrical protruding column of the moving plate 704 is attached to the outer side of the bottom opening of the oblique through slot of the push plate 9. During the rotation of the push plate 9, the slot walls of the six sets of oblique through slots push the cylindrical protruding column structure of the six sets of moving plates 704, so that the moving plate 704 drives the clamping block position adjustment device 7 to move synchronously centripetally or centrifugally, and completes the synchronous pushing and clamping work of the clamping plate 701 on the surface structure of the pump casing by the six sets of clamping block position adjustment device 7.

[0040] In this embodiment, the rack block 10 is a cuboid structure, and the left side of the rack block 10 is a toothed structure.

The outer side of the threaded rotating rod 8 is threadedly meshed with the threaded through hole of the rack block 10. The lower side of the rack block 10 is attached to the upper side of the bottom shell 2. During the process of the clamping knob 6 driving the threaded rotating rod 8 to rotate, the rack block 10 is driven to move back and forth along the upper side of the bottom shell 2, so that the rack block 10 pushes the push plate 9, which is meshed with the toothed structure, to rotate, thereby completing the synchronous pushing work of the six sets of oblique through slots on the push plate 9 to the six sets of moving plates 704.

[0041] The specific usage and function of this embodiment are as follows:

[0042] In this invention, when clamping and releasing the pump casing, the pump casing is first placed on the upper side of the top plate 3. Then, the clamping knob 6 is manually rotated, which drives the threaded rod 8 to rotate. Since the outer side of the threaded rod 8 is threadedly engaged in the threaded through hole of the rack block 10, and the tooth structure of the rack block 10 is engaged in the outer tooth structure of the pressure plate 9, as the rack block 10 moves against the upper side of the bottom shell 2, it drives the pressure plate 9 to rotate. The six sets of inclined through grooves on the upper side of the pressure plate 9 push the cylindrical protruding structure of the moving plate 704, so that the pressure plate 9 drives the clamping plates 701 of the six sets of clamping block position adjustment devices 7 to perform centrifugal or centripetal motion synchronously through the moving plate 704. This allows the six sets of clamping plates 701 to perform synchronous squeezing or releasing of the pump casing. When adjusting the clamping position of the clamping plates 701, the adjusting knob 70 is first manually rotated. 3. Adjusting knob 703 drives threaded adjusting rod 702 to rotate. Since the outer side of threaded adjusting rod 702 is threadedly engaged in the threaded through hole of convex plate of clamping plate 701, threaded adjusting rod 702 drives clamping plate 701 to move back and forth along the long groove of support shell 706. At this time, infrared ranging sensor 705 illuminates the reflector plate 707 attached to clamping plate 701. Reflector plate 707 reflects infrared light to infrared ranging sensor 705. Infrared ranging sensor 705 detects the movement distance of clamping plate 701 in long groove of support shell 706. Infrared ranging sensor 705 transmits the measured data signal to controller 4 through wire. Controller 4 digitizes the data signal and transmits it to digital display screen 5 through wire for display, allowing the user to perform high-precision adjustment of clamping position of clamping plate 701 according to the pump shell design parameters and the values ​​displayed on digital display screen 5.
