[0002] A water pump is a mechanical device used to transport liquids or increase the pressure of liquids. It converts mechanical energy into the kinetic energy or potential energy of liquids through methods such as impeller rotation or piston reciprocating motion, thereby achieving the suction, lifting, or pressurization of liquids; there are various types of water pumps, and common ones include centrifugal pumps, axial flow pumps, mixed flow pumps, vortex pumps, and positive displacement pumps (such as piston pumps, diaphragm pumps), etc., which are respectively suitable for different working conditions and liquid properties; water pumps are widely used in agricultural irrigation, industrial water supply, drainage and sewage disposal, fire protection, heating, ventilation, and air conditioning, etc.; during the processing of water pumps, jigs are usually required to position and clamp the pumps to facilitate subsequent processing operations.

[0003] Existing jigs for processing and positioning water pumps have a single processing and clamping structure. During processing, they can only position and clamp one pump cover part. At the same time, the clamping of the jig is mostly manual adjustment operation, which is time-consuming and laborious, and there is also a problem that the clamping is unstable due to insufficient adjustment force, thus reducing the processing efficiency. Moreover, the working table area of the existing positioning jig device is fixed, which affects the processing operation; therefore, in view of the above problems, improvements are now needed. Summary of the Invention

[0004] To achieve the above object, the present invention provides the following technical solution: A positioning jig device for water pump production and processing, including a device pedestal. A support ring pipe is fixedly installed on the top of the device pedestal. A large bearing is fixedly installed inside the support ring pipe. An inner ring of the large bearing is fixedly installed with a connecting ring pipe. A processing rotating table is fixedly installed on the top of the connecting ring pipe. A number of pump cover placement circular grooves are annularly and equidistantly arranged on the top of the processing rotating table. Adjustable clamping and fixing structures are installed inside each of the number of pump cover placement circular grooves. Two arc-shaped blocks for driving and adjusting the clamping and fixing structures are fixedly installed on the surface of the support ring pipe.

[0009] Preferably, two vertical grooves are formed at both ends of the top of the device pedestal. A first lifting and horizontal movement groove is formed at the bottom of each vertical groove. At one end of the bottom of each of the two extended placement plates, two insertion blocks are fixedly installed and inserted into the two first lifting and horizontal movement grooves. A first roller is rotatably installed at the lower part of each insertion block and is located inside the first lifting and horizontal movement groove.

[0010] Preferably, the two extended adjustment mechanisms include triangular grooves formed at both ends of the two device pedestals. The two triangular grooves are symmetrically arranged and are located between the middle parts of the four first lifting and horizontal movement grooves. At the same time, a rectangular inner groove is formed at the bottom of each of the two triangular grooves. Second lifting and horizontal movement grooves are formed on both sides inside each of the two rectangular inner grooves. A rectangular block is slidably installed inside each of the two rectangular inner grooves. A vertical through groove is formed at the upper part of each of the two rectangular blocks, and the height of the vertical through groove matches that of the second lifting and horizontal movement groove.

[0013] Preferably, inclined plane structures are formed at the opposite ends of the two extended placement plates. Inner inclined grooves matching the inclined planes at the ends of the extended placement plates are formed at both ends of the top of the device pedestal.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] (1) The positioning fixture device for water pump production and processing has a multi-station rotary automatic positioning and clamping structure. The multi-stations can effectively increase the quantity of processing, and the rotary automatic positioning and clamping structure can effectively ensure the reliability of clamping adjustment and the firmness of clamping, thus effectively guaranteeing the efficiency and speed of water pump processing. At the same time, the positioning fixture device for water pump production and processing has an expandable operation tabletop, which increases the usable area of processing operations, facilitates the disassembly and assembly operations of the water pump, and the structure of this positioning fixture device is simply designed, convenient and easy to use and operate, with stable and reliable adjustment, and its performance can meet the usage requirements of water pump production and processing;

[0016] (2) By starting the first motor to rotate at regular intervals by a certain angle or manually controlling the first motor to rotate by a certain angle, the regular rotation of the first motor is controlled by an external controller; the start of the first motor will drive the first transmission gear to rotate, and the rotation of the first transmission gear will drive the internal gear ring, so that the internal gear ring drives the connecting ring pipe and the processing rotary table to rotate by a certain angle through the large bearing; the rotation of the processing rotary table by a certain angle can drive the pump cover inside the pump cover placement circular groove to rotate and move through the clamping and fixing structure, thus facilitating the processing of the pump cover.

[0017] (3) When the processing turntable drives the circular groove for placing the pump cover and the clamping and fixing structure to rotate, the worker sequentially places the pump cover to be processed into the circular groove for placing the pump cover, so that the pump cover rotates with the processing turntable, the circular groove for placing the pump cover and the clamping and fixing structure. The rotation of the processing turntable drives the bevel gear to rotate, making the bevel gear contact the helical teeth on one of the arc-shaped blocks and perform rolling rotational movement. The rolling rotational movement of the bevel gear drives the bidirectional threaded shaft to rotate. The rotation of the bidirectional threaded shaft causes the two sliders on it to slide relatively inside the two sliding grooves, driving the two arc-shaped clamping plates to perform positioning clamping and fixing operations on the pump cover placed inside the circular groove for placing the pump cover. Then, as the processing turntable rotates in a circle, the bevel gear contacts the helical teeth on the other arc-shaped block and performs rolling rotational movement. At this time, the rotation direction of the bevel gear is opposite to the direction adjusted during the above clamping rotation. Therefore, finally, the two arc-shaped clamping plates are separated from the positioned and clamped pump cover, facilitating the removal of the processed pump cover, and then placing the pump cover to be processed into the circular groove for placing the pump cover again, effectively realizing the continuity of processing.

[0018] (4) Through the two expanded extended placement plates, the tops of the two extended placement plates are flush with the top of the device pedestal, facilitating the cooperation between the two extended placement plates and the top of the device pedestal to place the pump cover to be processed and the processed pump cover, thereby improving the convenience of processing. When it is necessary to perform contraction adjustment on the two extended placement plates to reduce the occupied space position, the second motor is started to make the second driving gear rotate. The rotation of the second driving gear moves the two driving racks, so that the two adjusting plates drive the two rectangular blocks to move towards the transmission groove inside the two rectangular inner grooves. The movement of the rectangular blocks drives the mounting shaft and the second roller at the end of the mounting shaft to move through the vertical through groove, so that the second roller moves inside the second lifting and horizontal movement groove. The movement of the rectangular blocks drives the extended placement plate to move through the ejector rod and the connecting block. The movement of the extended placement plate drives the first roller to move inside the first lifting and horizontal movement groove through the insertion block. The movement trajectories of the second roller and the first roller are the same, and they synchronously perform horizontal movement, inclined upward movement, and horizontal movement again, so that the two extended placement plates are inclined upward and moved from the inside of the two inner inclined grooves to the top of the device pedestal for contraction adjustment.

Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1 is given by Figures 1 to 10 The present invention includes a device pedestal 1. A support ring pipe 2 is fixedly installed on the top of the device pedestal 1. A large bearing 3 is fixedly installed inside the support ring pipe 2. An inner ring of the large bearing 3 is fixedly installed with a connecting ring pipe 4. A processing rotating table 5 is fixedly installed on the top of the connecting ring pipe 4. A plurality of pump cover placement circular grooves 6 are annularly and equidistantly formed on the top of the processing rotating table 5. An adjustable clamping and fixing structure 7 is installed inside each of the plurality of pump cover placement circular grooves 6. Two arc-shaped blocks 8 for driving and adjusting the clamping and fixing structure 7 are fixedly installed on the surface of the support ring pipe 2. Adjustable extended placement plates 9 are installed at both ends of the top of the device pedestal 1. Extended adjustment mechanisms for adjusting the extended placement plates 9 are installed at both ends of the device pedestal 1.

[0034] A internal gear ring 10 is fixedly installed at the lower part inside the connecting ring pipe 4. A first motor 11 is installed on the top of the device pedestal 1 inside the support ring pipe 2. An output end of the first motor 11 is fixedly installed with a first transmission gear 12 meshed with the internal gear ring 10. A plurality of balls 13 in contact with the bottom of the processing rotating table 5 are annularly and equidistantly installed on the top of the support ring pipe 2, so as to effectively rotate the processing rotating table 5 and facilitate the processing of the pump cover inside the pump cover placement circular groove 6, such as other processing operations for fixing the pump cover, like opening holes on the surface.

[0035] Specifically, by starting the first motor 11 to rotate at a fixed time and at equal angles or by manually controlling the first motor 11 to rotate at equal angles, the fixed-time rotation of the first motor 11 is controlled by an external controller. The start of the first motor 11 will drive the first transmission gear 12 to rotate. The rotation of the first transmission gear 12 will drive the internal gear ring 10, so that the internal gear ring 10 drives the connecting ring pipe 4 and the processing rotating table 5 to rotate at equal angles through the large bearing 3. The equal-angle rotation of the processing rotating table 5 can drive the pump cover inside the pump cover placement circular groove 6 to rotate and move through the clamping and fixing structure 7, thus facilitating the processing of the pump cover.

[0036] The positioning fixture device for the production and processing of this water pump has a multi-station rotating automatic positioning and clamping structure. The multi-station can effectively increase the number of processed items, while the rotating automatic positioning and clamping structure can effectively ensure the reliability of clamping adjustment and the firmness of clamping, thus effectively ensuring the efficiency and speed of water pump processing. At the same time, the positioning fixture device for the production and processing of this water pump has an expandable operating table, and the expandable operating table increases the usable area of processing operations, facilitating the disassembly and assembly operations of the water pump. Moreover, the structure of this positioning fixture device is simply designed, easy to use and operate, with stable and reliable adjustment. Its performance can meet the usage requirements of water pump production and processing.

[0037] Embodiment 2, on the basis of Embodiment 1, several clamping and fixing structures 7 each include two inner grooves 14 symmetrically opened inside several pump cover placing circular grooves 6. Inside the two inner grooves 14 inside the pump cover placing circular grooves 6, there are arc-shaped clamping plates 15 for clamping and tightly fixing the pump cover. At the bottom of each inner groove 14, a sliding groove 16 is opened, and the sliding grooves 16 all extend to the bottom of the processing rotating table 5. And inside the sliding grooves 16, sliders 17 are slidably installed, and the arc-shaped clamping plates 15 are all fixedly connected to the adjacent sliders 17.

[0038] A number of pairs of fixing blocks 18 are fixedly installed at equal intervals in a ring at the bottom of the processing rotating table 5. The fixing blocks 18 are aligned with the sliding grooves 16 and are located on one side below the sliding grooves 16. A bidirectional threaded shaft 19 is rotatably installed between each pair of fixing blocks 18. The lower part of the slider 17 is threadedly connected to the bidirectional threaded shaft 19. And at one end of each bidirectional threaded shaft 19, a bevel gear 20 is fixedly installed. The two arc-shaped blocks 8 are arranged up and down and left and right in a staggered manner on the surface of the support ring tube 2. On one side where the two arc-shaped blocks 8 are close to each other, inclined surfaces 21 are opened. On the two inclined surfaces 21, helical teeth 22 that match the bevel gear 20 and alternately drive the bevel gear 20 to rotate are opened, so that the clamping and fixing structure 7 can be effectively adjusted, enabling the clamping and fixing structure 7 to clamp and fix the pump cover. At the same time, through cyclic rotation, the clamping and fixing structure 7 can also loosen the clamped and fixed pump cover.

[0039] Specifically, when the processing turntable 5 drives the circular groove 6 for placing the pump cover and the clamping and fixing structure 7 to rotate, the worker sequentially places the pump cover to be processed into the inside of the circular groove 6 for placing the pump cover, so that the pump cover rotates with the processing turntable 5, the circular groove 6 for placing the pump cover and the clamping and fixing structure 7. The rotation of the processing turntable 5 drives the bevel gear 20 to rotate, so that the bevel gear 20 contacts the helical teeth 22 on one of the arc-shaped blocks 8 and rolls and rotates. The rolling and rotating movement of the bevel gear 20 drives the bidirectional threaded shaft 19 to rotate. The rotation of the bidirectional threaded shaft 19 causes the two sliders 17 on it to slide relative to each other inside the two sliding grooves 16, driving the two arc-shaped clamping plates 15 to perform positioning and clamping operations on the pump cover placed inside the circular groove 6 for placing the pump cover;

[0040] After that, with the circular rotation of the processing turntable 5, the bevel gear 20 will contact the helical teeth 22 on another one of the arc-shaped blocks 8 and roll and rotate. At this time, the rotation direction of the bevel gear 20 is opposite to the direction adjusted during the above-mentioned clamping rotation. Therefore, finally, the two arc-shaped clamping plates 15 are separated from the positioned and clamped pump cover, facilitating the removal of the processed pump cover, and then the pump cover to be processed is placed into the inside of the circular groove 6 for placing the pump cover again, effectively realizing the continuity of processing; and the adjustment of the bidirectional threaded shaft 19 can effectively ensure the reliability and firmness of the clamping of the two arc-shaped clamping plates 15.

[0041] Embodiment 3, on the basis of Embodiment 1, two vertical grooves 23 are respectively opened at both ends of the top of the device pedestal 1. The bottom of each vertical groove 23 is provided with a first lifting and horizontal movement groove 24. One end of the bottom of each of the two extended placement plates 9 is fixedly installed with two insertion blocks 25 inserted into the inside of the two first lifting and horizontal movement grooves 24. The lower parts of the insertion blocks 25 are rotatably installed with first rollers 26 located inside the first lifting and horizontal movement grooves 24.

[0042] The two expansion adjustment mechanisms include triangular grooves 27 opened at both ends of the two device pedestals 1. The two triangular grooves 27 are symmetrically arranged and are located between the middles of the four first lifting and horizontal movement grooves 24. At the same time, rectangular inner grooves 28 are opened at the bottoms of the two triangular grooves 27. Second lifting and horizontal movement grooves 29 are opened on both sides inside the two rectangular inner grooves 28. And rectangular blocks 30 are slidably installed inside the two rectangular inner grooves 28. Vertical through grooves 31 are opened at the upper parts of the two rectangular blocks 30. The height of the vertical through grooves 31 matches that of the second lifting and horizontal movement grooves 29. Installation shafts 32 are installed inside the two vertical through grooves 31. Second rollers 33 located inside the second lifting and horizontal movement grooves 29 are installed at both ends of the two installation shafts 32. The middle parts of the tops of the two rectangular blocks 30 are rotatably connected to ejector rods 34. Connecting blocks 35 are fixedly installed at the other ends of the bottoms of the two expansion placement plates 9. One ends of the two ejector rods 34 are rotatably connected to the two connecting blocks 35 through the two triangular grooves 27 respectively, so as to effectively adjust the expansion placement plates 9.

[0043] A transmission groove 36 is opened between the opposite ends of the two rectangular inner grooves 28. A second motor 37 is installed on one side of the transmission groove 36. A second transmission gear 38 is fixedly installed at the output end of the second motor 37. Adjusting plates 39 which are vertically offset are fixedly installed on the opposite sides of the two rectangular blocks 30. Transmission racks 40 are fixedly installed on the opposite sides of the two adjusting plates 39. The second transmission gear 38 is meshed and connected between the two transmission racks 40. U-shaped plates 41 are fixedly installed at the ends of the two adjusting plates 39 away from the rectangular blocks 30. The two adjusting plates 39 respectively slide through and are installed inside the two U-shaped plates 41, so as to synchronously adjust the two expansion placement plates 9 to contract or expand.

[0044] Bevel structures are opened at the opposite ends of the two expansion placement plates 9. Inner bevel grooves 42 matching the end bevels of the expansion placement plates 9 are opened at both ends of the top of the device pedestal 1. One ends of the vertical grooves 23 and the first lifting and horizontal movement grooves 24 both penetrate to the middle of the inner bevel grooves 42. The expansion placement plates 9 are located inside the inner bevel grooves 42. And the top of the expansion placement plates 9 located inside the inner bevel grooves 42 is flush with the top of the device pedestal 1. The two first lifting and horizontal movement grooves 24 at the end of the device pedestal 1 and the two second lifting and horizontal movement grooves 29 are arranged parallel and aligned vertically. And the first lifting and horizontal movement grooves 24 and the second lifting and horizontal movement grooves 29 are composed of upper horizontal long sliding segments, middle inclined sliding segments and lower horizontal short sliding segments, so that the expansion placement plates 9 can be effectively expanded and adjusted for use;

[0045] Specifically, as shown in the attached drawings, by means of two unfolded extended placement plates 9, the tops of the two extended placement plates 9 are flush with the top of the device pedestal 1, so as to facilitate the cooperation between the two extended placement plates 9 and the top of the device pedestal 1 for placing the pump cover to be processed and the processed pump cover, thereby improving the convenience of processing;

[0046] When it is necessary to perform contraction adjustment on the two extended placement plates 9 to reduce the occupation of space position, the second motor 37 is started to rotate the second transmission gear 38. The rotation of the second transmission gear 38 will move the two transmission racks 40, so that the two adjusting plates 39 drive the two rectangular blocks 30 to move towards the transmission groove 36 inside the two rectangular inner grooves 28. The movement of the rectangular block 30 will drive the mounting shaft 32 and the second roller 33 at the end of the mounting shaft 32 to move through the vertical through groove 31, so that the second roller 33 moves inside the second lifting and horizontal movement groove 29. And the movement of the rectangular block 30 will drive the extended placement plate 9 to move through the ejector rod 34 and the connecting block 35. The movement of the extended placement plate 9 will drive the first roller 26 to move inside the first lifting and horizontal movement groove 24 through the insertion block 25. The movement tracks of the second roller 33 and the first roller 26 are the same, and they move horizontally, tilt upward and move horizontally again synchronously, so that the two extended placement plates 9 are tilted upward from inside the two inner inclined grooves 42 and move to the top of the device pedestal 1 for contraction adjustment.
