Description

Technical Field

[0001] The utility model relates to the field of pump casing processing, in particular to a clamping tool for pump casing processing. Background Art

[0002] A pump is a machine that transports fluids or pressurizes fluids. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. Pumps are mainly used to transport liquids such as water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. They can also transport liquid-gas mixtures and liquids containing suspended solids.

[0003] After searching the patent document with the publication number CN219818888U, the patent document discloses "a clamping tool for processing a water pump housing, which sets the water pump housing on the locking protrusion, and the driving component controls the horizontal displacement of the horizontal slider, so that the locking protrusion locks the water pump housing from the inner side of the water pump housing; after the water pump housing is locked, the rotating motor drives the circular rotating table to rotate so that the water pump housing can rotate 360 degrees, so that the side that needs to be deburred is aligned with the drill bit, so that the burrs on the water pump housing are removed, so that the water pump housing does not need to be repeatedly disassembled, thereby making the work efficiency higher.";

[0004] When the above device is in operation, the two locking protrusions are moved to make the locking protrusions press against the inner walls at both ends of the pump casing, thereby clamping and fixing the pump casing. However, if such clamping is performed on a larger pump casing, the pump casing may be easily offset due to external forces at the front and rear ends, thereby affecting subsequent processing. Utility Model Content

[0005] The purpose of the utility model is to provide a clamping tool for pump housing processing in order to solve the above-mentioned problem.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] A clamping tool for processing a pump housing, comprising a bottom plate, a rotating mechanism installed on the upper end of the bottom plate, and a fixing mechanism;

[0008] The fixing mechanism includes a fixing seat, which is installed at the upper end of the rotating mechanism. A bidirectional screw is rotatably connected inside the fixing seat, and a second motor is installed at the input end of the bidirectional screw. Two sliding frames are threadedly connected to the outer periphery of the bidirectional screw, and the sliding frames are slidably connected to the fixing seat. A plurality of unidirectional screws are rotatably connected to the inner portions of the two sliding frames. A slider is threadedly connected to the outer periphery of each unidirectional screw, and the slider is slidably connected to the corresponding sliding frame. A column is fixed to the upper end of the slider, and a sleeve is provided on the outer periphery of the column. An insertion rod is penetrated through the bottom of the sleeve, and a plurality of through holes are opened on the column body corresponding to the size of the insertion rod, and a top block is fixed to the upper end of the sleeve.

[0009] Preferably: The one-way screws inside each sliding bracket are evenly distributed, and a turning handle is provided at one end of the one-way screw.

[0010] Preferably: The multiple through holes opened in the column wall corresponding to the insertion rods are evenly distributed, and the length of the insertion rod is the same as the length of the upper end surface of the slider.

[0011] Preferably: A rubber layer is provided on the surface of the top block, and arc surfaces are provided at both ends and the edges of the upper end surface of the top block.

[0012] Preferably: Through holes are opened at the four corners of the bottom plate.

[0013] Preferably: The rotating mechanism includes a first motor, the first motor is installed in the middle of the upper end of the bottom plate, a turntable is fixed to the output end of the first motor, a support ring is provided around the first motor, and the support ring is fixed to the bottom plate and is rotatably connected to the lower end of the turntable.

[0014] The beneficial effects compared with the prior art are as follows:

[0015] When the device is operating, through the threaded connection between the slider and the one-way screw and the sliding connection between the slider and the sliding bracket, when the one-way screw is rotated, the slider can be moved, so that the multiple top blocks on each sliding bracket can be adjusted in position as needed. Then, the second motor is started. Through the threaded connection between the sliding bracket and the bidirectional screw and the sliding connection between the sliding bracket and the fixed seat, when the second motor is started, the two sliding brackets can be moved, so that the multiple adjusted top blocks on the two sliding brackets will hold against the inner wall of the pump housing. Due to the position adjustment of the top blocks, after the pump housing is clamped and fixed, the multiple top blocks of the device can better fit the inner wall of the pump housing, which can avoid the situation that the front and rear ends of the pump housing will shift when subjected to external forces;

[0016] Before the device is used, the device can be adjusted according to the size and structure of the inner wall of the pump housing. By pulling out the insertion rod, the corresponding top block can be adjusted in height or directly removed. Coupled with the fact that each slider can be independently adjusted in position, the applicability of the device is better in this way. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The fixing mechanism includes a fixing base 3, which is installed at the upper end of the rotating mechanism. A bidirectional screw 31 is rotatably connected inside the fixing base 3. The input end of the bidirectional screw 31 is installed with a second motor 32. Two sliding frames 33 are threadedly connected to the periphery of the bidirectional screw 31, and the sliding frames 33 are slidably connected to the fixing base 3. A plurality of unidirectional screws 34 are rotatably connected inside both sliding frames 33. The unidirectional screws 34 inside each sliding frame 33 are evenly distributed, and a turning handle is provided at one end of the unidirectional screw 34. A slider 35 is threadedly connected to the periphery of each unidirectional screw 34, and the slider 35 is slidably connected to the corresponding sliding frame 33. A column 36 is fixed to the upper end of the slider 35. A sleeve 37 is sleeved on the periphery of the column 36. A plug rod 38 is provided through the bottom of the sleeve 37. A plurality of through holes corresponding to the plug rod 38 are evenly distributed on the wall of the column 36.

A plurality of through holes corresponding to the size of the plug rod 38 are provided on the column body of the column 36. A top block 39 is fixed to the upper end of the sleeve 37. A rubber layer is provided on the surface of the top block 39, and arc surfaces are provided at both ends and the edges of the upper end surface of the top block 39; during the operation of the device, through the threaded connection between the slider 35 and the unidirectional screw 34 and the sliding connection between the slider 35 and the sliding frame 33, when the unidirectional screw 34 is rotated, the slider 35 can be moved.

After adjusting the device to a structure and size suitable for the inner wall of the pump housing, put the pump housing on the outer ring of the top block 39. Subsequently, start the second motor 32 again, and make the two sliding frames 33 move in opposite directions, so that each top block 39 presses against the inner wall of the pump housing, thereby clamping and fixing the pump housing. When operating, start the first motor 2, and drive the rotation of the turntable 21 through the first motor 2, so that the fixed pump housing rotates.
