[0002] Pumps play an important role in industrial systems, especially in liquid medium supply systems, where they are irreplaceable. The operating performance and service life of the pump directly affect the quality level of the entire system. During the production and processing of the pump, it is composed of suction components, impeller components, pump body components, bearing components, shaft seal components, pump cover and other auxiliary devices. Most of its components are irregular in shape, and drilling work is required during the production of the pump cover to facilitate assembly on the pump body.

[0003] At present, when drilling holes in the pump cover, the two sides of the pump cover are generally clamped and positioned by a clamp. The pump cover needs to be clamped in the air to facilitate the subsequent rotation and hole turning of the pump cover. However, when clamping the pump cover, the bottom of the pump cover needs to be supported to prevent the pump cover from falling and causing the clamping to be out of place, further reducing the working efficiency of the clamping tooling.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 3 The utility model provides a technical solution: an adjustable clamping and positioning tool for drilling a pump cover, comprising a mounting base plate 1, a driving mechanism 2 is arranged on the top of the mounting base plate 1, a clamping mechanism 3 is connected to the top of the driving mechanism 2, and a supporting mechanism 4 is fixedly connected to the top of the mounting base plate 1; wherein the supporting mechanism 4 comprises a cylinder 41 fixed to the top of the mounting base plate 1, a supporting plate 42 is fixedly connected to the output end of the cylinder 41, a supporting plate 42 is fixedly connected to the top of the supporting plate 42 is fixedly connected to a supporting spring 43, a placing plate 44 is connected to the top of the supporting spring 43, and a touch switch 45 is arranged on the supporting plate 42 and the placing plate 44. Driven by the cylinder 41, the supporting plate 42 can be adjusted up and down, so that after the pump cover on the placing plate 44 is clamped, it can be lowered to the lowest position to prevent affecting the pump cover hole rotating operation.

[0022] according to Figure 1 It can be known that the driving mechanism 2 includes a fixed plate 21 fixed on the top of the mounting base plate 1, and the side wall of the fixed plate 21 is rotatably connected to a bidirectional screw rod 22 through a bearing, and the other side of the fixed plate 21 is fixedly connected to a servo motor 23, and the output end of the servo motor 23 is fixedly connected to the bidirectional screw rod 22, and the surface of the bidirectional screw rod 22 is threadedly connected to the clamping mechanism 3. Under the setting of the fixed plate 21, the bidirectional screw rod 22 can be connected to the bearing, and then driven by the servo motor 23, the bidirectional screw rod 22 can be rotated, so that the clamping mechanism 3 can be adjusted for displacement, so that the two sides of the pump cover can be quickly clamped and fixed.

[0023] according to Figure 3It can be known that the clamping mechanism 3 includes a movable seat 31 threadedly connected to the surface of the bidirectional screw rod 22, the surface of the movable seat 31 is rotatably connected to the rotating shaft 32 through a bearing, the end of the rotating shaft 32 is fixedly connected to a rotating disk 33, and the surface of the rotating disk 33 is provided with a protective pad 34. The movable seat 31 is threadedly connected to the surface of the bidirectional screw rod 22, so that the two movable seats 31 can be synchronously adjusted in displacement when the bidirectional screw rod 22 rotates, so that the two sides of the pump cover can be quickly clamped and fixed.

[0024] In addition, the end of the rotating shaft 32 may be provided with a motor, so that the rotating shaft 32 can be rotated, thereby rotating the clamped pump cover, so as to process the pump cover positions in different directions.

[0025] according to Figure 3 It can be seen that a clamping block 35 is fixedly connected to the surface of the protective pad 34, and a clamping groove 36 is opened on the surface of the rotating disk 33. The end of the clamping block 35 is rotatably clamped in the clamping groove 36. By setting the clamping block 35 on the surface of the protective pad 34, the clamping block 35 can be clamped in the inside of the clamping groove 36, so that the rotating disk 33 and the protective pad 34 can be assembled, which is convenient for replacing protective pads 34 of different shapes to clamp the pump cover.

[0026] according to Figure 1 It can be seen that a collection frame 46 is installed inside the placement plate 44. The collection frame 46 is square in shape. Under the setting of the collection frame 46, it can collect waste chips during drilling to prevent the waste chips from falling onto the installation base plate 1 and affecting the difficulty of subsequent cleaning.

[0027] according to Figure 1 It can be seen that the side wall of the fixed plate 21 is fixedly connected with a guide rod 24, and the surface of the guide rod 24 is slidably connected to the clamping mechanism 3. Under the setting of the guide rod 24, it can play a guiding role when the clamping mechanism 3 is displaced.

[0028] The working principle of the utility model is as follows: when in use, firstly, the support mechanism 4 is set on the top of the installation base plate 1 so that the pump cover can be placed, and then the driving mechanism 2 is driven to drive the clamping mechanism 3 to adjust the displacement, and the displacement of the clamping mechanism 3 can position and clamp the two sides of the pump cover above the support mechanism 4, and under the drive of the cylinder 41 included in the support mechanism 4, the support plate 42 can be raised, and then the placement plate 44 fixed by the support spring 43 is located at the center of the installation base plate 1. At this time, when the pump cover is placed, the placement plate 44 can compress the support spring 43 by the weight of the pump cover itself, so that the touch switch 45 on the support plate 42 and the placement plate 44 can be in contact and energized to work, so as to control the driving mechanism 2 to drive automatically, thereby driving the clamping mechanism 3 to quickly clamp and fix the two sides of the pump cover, and when the pump body is clamped, the support plate 42 is reset by the cylinder 41, so that the touch switch 45 can be automatically separated under the elastic force of the support spring 43 to turn off the work of the driving mechanism 2.
