Description

Technical Field

[0001] The utility model relates to the technical field of pump casing positioning structures, in particular to a positioning structure of a pump casing processing device. Background Art

[0002] Pumps are of various types according to their principles and uses, and the shapes of pumps are also different. Some pump casings are volute-shaped, and have shaft holes or pipe openings inside. Due to their irregular structures, when machining such as grinding the outside of the pump casing, targeted positioning structures are required to ensure the stability of the casing during the machining process.

[0003] Chinese patent authorization announcement number CN217776778U discloses a positioning tool for rear pump shell processing, including a bottom plate, a cross-shaped slide groove is provided on the bottom plate, and four sliding plates are slidably installed through the cross-shaped slide groove. The upper surfaces of the four sliding plates are fixedly installed with positioning components that can clamp and position the rear pump shell, and the rear pump shell is squeezed and fixed, so as to complete the positioning and clamping of the rear pump shell. The clamping effect is good, ensuring that the workpiece will not deviate and shake during the processing, and the processing accuracy of the workpiece is improved. It can be used for clamping and positioning operations on rear pump shells of different sizes, and has a wide range of applications. The above-mentioned prior art solution has the following shortcomings: the positioning tool mainly realizes the fixing of the pump shell by moving the sliding plates inward in four different directions and cooperating with the movement of the pressure plate. However, since the movement of each sliding plate and the pressure plate in the clamping work requires the cooperation of separate screw rods and other components, it is necessary to adjust the position of the parts one by one during use, and there are many operation steps, which affects its convenience of use. For this, the present application proposes an improved solution. Utility Model Content

[0025] And the first guide hole 2 is penetrated by a movable block 3;

[0026] Balls 14 are evenly embedded on both sides of the movable block 3, and a groove is correspondingly provided on the inner wall of the movable block 3 on one side of the ball 14, and the outer sides of the ball 14 are against the inside of the groove to reduce the left and right movement resistance of the movable block 3 in the first guide hole 2;

[0027] The top of each movable block 3 is provided with a bottom plate 4, and the inner side of the top of each bottom plate 4 is provided with a clamping plate 6;

[0028] A pressing pad 15 is installed on the outer side of the clamping plate 6, and the pressing pad 15 is made of silicone material, and the outer side of the pressing pad 15 is an arc-shaped curved surface;

[0029] Specifically, Figure 1 , Figure 3 As shown, when in use, the function of the ball 14 is utilized to improve the smoothness of the left and right sliding of the movable block 3, and the function of the squeeze pad 15 is utilized to reduce the rigid contact between the clamping plate 6 and the pump housing, thereby avoiding damage to the pump housing during the clamping process;

[0030] An upper clamping mechanism 5 is provided at the top of the clamping plate 6 to limit the top of the pump housing. The upper clamping mechanism 5 includes a fixed column 502 installed at the top of the clamping plate 6, and a rotating plate 501 is sleeved on the outside of the fixed column 502. One side of the bottom end of the rotating plate 501 is evenly installed with an extrusion protrusion 503;

[0031] The rotating plate 501 is rotatably connected to the fixed column 502, and the top view length of the rotating plate 501 is greater than the top view length of the clamping plate 6;

[0032] Specifically, Figure 1 , Figure 4 As shown, when in use, the rotating plate 501 is rotated to cooperate with the bottom plate 4 when it rotates outward to form an upper and lower limit function for the pump housing, further improving the stability of the pump housing;

[0033] An electric telescopic rod 12 is installed at the bottom end of the positioning platform 1, and a lifting block 11 is installed at the bottom end of the electric telescopic rod 12. Guide plates 8 are evenly installed on the outer wall of the lifting block 11, and second guide holes 9 are opened inside the guide plates 8.

[0034] The second guide holes 9 are distributed obliquely on the guide plate 8, and the two second guide holes 9 on the left and right are distributed in an inverted eight-shaped pattern, and the projected length of the second guide holes 9 is adapted to the horizontal length of the first guide holes 2;

[0037] Working principle: When the utility model is used, firstly, the rotating plate 501 is kept in an inwardly rotating state, and then the pump housing is placed on the four bottom plates 4 from top to bottom, so that the four clamping plates 6 penetrate the shaft holes inside the pump housing, thereby starting the electric telescopic rod 12 to extend, so that the guide plate 8 moves downward along the guide rod 13, and the second guide hole 9 is synchronously lowered. Since the bottom plate 4 is located at the top of the positioning platform 1, the roller 10 moves along the second guide hole 9 through the guiding effect of the second guide hole 9, and a horizontal displacement occurs, thereby driving the four connecting plates 7 to move outward synchronously, so that the movable block 3 moves outward along the first guide hole 2;

[0038] Secondly, under the outward movement of the movable block 3, the bottom plate 4 moves synchronously, and the four clamping plates 6 expand and move outward, so that the ball 14 presses against the inner wall of the shaft hole of the pump housing to achieve internal clamping and fixing of the pump housing;

[0039] Finally, the four rotating plates 501 are rotated outwards, so that the extrusion protrusion 503 is rotated to the top of the pump housing and contacts it, so that it cooperates with the bottom plate 4 to achieve the upper and lower limit of the pump housing.
