Technical Field

[0001] The utility model relates to the technical field of position gauges for machining water pumps, and particularly relates to a position gauge for machining water pumps. Background Art

[0002] A water pump is a machine that transports liquids or increases the pressure of liquids. It transmits the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. It is mainly used to transport liquids including water, oil, acid-base liquids, emulsions, suspension liquids, and liquid metals, etc. It can also transport liquid-gas mixtures and liquids containing suspended solids. The technical parameters of the performance of the water pump include flow rate, suction lift, head, shaft power, water power, efficiency, etc.; according to different working principles, it can be divided into types such as positive displacement pumps and vane pumps. A positive displacement pump uses the change in the volume of its working chamber to transfer energy; a vane pump uses the interaction between the rotating vane and water to transfer energy, and there are types such as centrifugal pumps, axial flow pumps, and mixed flow pumps;

[0003] After the machining of the water pump machine is completed, it is necessary to detect the position degree of the machining holes on the side wall. Since there is no gauge, it is impossible to judge whether the processed product meets the requirements of the product drawing, resulting in a large number of unqualified product dimensions, and thus the product is scrapped. Generally, the existing position degree detection devices use manual detection of the position degree, with low detection accuracy. At the same time, during the detection process, due to the different models of the processed water pumps, it is impossible to use the same device for fixed detection, resulting in difficulties in detecting the position degree.

[0007] Preferably, a first clamping groove is recessed inwardly on the outer wall of the storage groove, a second clamping groove is formed on the outer wall of the extrusion block, and the telescopic spring is sleeved outside the storage groove and the extrusion block through the first clamping groove and the second clamping groove.

[0008] Preferably, one side of the positioning block gradually becomes smaller, and the pin gauge is inclined at a certain angle inside the positioning block.

[0009] Preferably, a threaded rod is movably connected to the middle of the adjustment block.

[0010] Preferably, fixing screws are rotatably connected to both ends of the positioning block, and the positioning block is fixedly connected to the top of the base through the fixing screws.

[0019] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: a position degree inspection tool for machining of a water pump. It includes a base 1, and three positioning blocks 3 are fixedly connected to the top of the base 1. The base 1 is used for positioning products and fixing the pin gauge 2, positioning blocks 3 and handle 5. The pin gauge 2 penetrates through the inside of the three positioning blocks 3. The positioning block 3 is made of 45 steel quenched to HRC45 - HRC55, with high hardness, wear resistance, and high stiffness and strength. The pin gauge 2 is used to detect the size of the product hole. Four corners of the base 1 are fixedly connected with adjusting blocks 4. By screwing the adjusting block 4, the threaded rod movably connected in the middle rotates, thereby adjusting the horizontal position and height of the tooling. A fixing hole 6 is opened in the middle of the base 1, and a placing groove 8 is fixedly connected to the bottom of the fixing hole 6. The placing groove 8 is used for placing the water pump. A connecting hole 10 is opened on the side of the placing groove 8, and an extrusion block 9 is clamped inside the connecting hole 10. The extrusion block 9 is used to detect the water pump to be detected placed inside the placing groove 8. A telescopic spring 11 is sleeved outside the placing groove 8. When the water pump squeezes the extrusion block 9, the telescopic spring 11 contracts inward and applies a clamping force to the water pump through the extrusion block 9 to clamp the water pump.

[0021] Please refer to Figures 1-4 , handles 5 are fixedly connected to both ends of the base 1. The handles 5 are used to conveniently move the tooling. A first card slot 12 is recessed inward on the outer wall of the placing groove 8, and a second card slot 13 is opened on the outer wall of the extrusion block 9. The telescopic spring 11 is sleeved outside the placing groove 8 and the extrusion block 9 through the first card slot 12 and the second card slot 13. The first card slot 12 and the second card slot 13 can clamp the telescopic spring 11 inside to prevent the telescopic spring 11 from detaching from the outer wall of the placing groove 8. One side of the positioning block 3 gradually becomes smaller, and the pin gauge 2 is inclined at a certain angle inside the positioning block 3, which is convenient for detecting the position degree of the water pump. A threaded rod is movably connected to the middle of the adjusting block 4, and fixing screws 7 are rotatably connected to both ends of the positioning block 3. The positioning block 3 is fixedly connected to the top of the base 1 through the fixing screws 7.

[0022] During use, first place the water pump in the interior of the placement groove 8. Since a plurality of extrusion blocks 9 are clamped to the inner wall of the placement groove 8, when different models of water pumps produced are placed in the interior of the placement groove 8 for inspection and the extrusion blocks 9 are squeezed, the telescopic springs 11 clamped to the outside of the placement groove 8 and the extrusion blocks 9 are stressed to generate an inward contraction force, causing the extrusion blocks 9 to clamp the water pump. The position degree of the produced water pump is detected in three directions on the top of the base 1 by the pin gauge 2 and the positioning block 3, ensuring the consistency of the size and precision of the produced water pump and avoiding that the produced water pump cannot meet the requirements of the product drawing.
