DETAILED DESCRIPTION

[0045] The following will be combined with 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 of 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.

[0046] like Figure 1 to Figure 4 As shown, the utility model proposes a water pump as-needed assembly fixture, including a workbench 1, a mounting frame 2, a clamping mechanism, a clamping block 3, an adjustment clamping assembly, a spring telescopic rod 4 and a positioning assembly, wherein the mounting frame 2 is provided with two, and the two mounting frames 2 are slidably connected to the workbench 1, the clamping mechanism is installed on the mounting frame 2, the clamping block 3 is provided with a plurality of, and the plurality of clamping blocks 3 are slidably connected to the mounting frame 2, and the adjustment clamping assembly is installed on the mounting frame 2, wherein the adjustment clamping assembly includes a spring telescopic rod 4, and the spring telescopic rod 4 is provided with a plurality of A plurality of spring telescopic rods 4 are fixedly connected with the clamping block 3, and the positioning assembly is installed on the workbench 1. When the water pump starts to be installed, the pump casing is first placed on the positioning assembly, and then the positioning assembly fixes the pump casing in the clamping area formed by the two mounting frames 2. The clamping mechanism is started to preliminarily fix the pump casing, and then the clamping assembly is adjusted to start, and the pump casing is clamped and fixed laterally and longitudinally, and the fixing effect is better. The clamping block 3 is adapted to the shape of the pump casing through the spring telescopic rod 4, so that the pump casing is not easy to deviate, thereby making the assembled effect more precise.

[0047] Among them, the clamping mechanism includes a bidirectional screw 5, a slider 6, a motor 7 and a clamping frame 8. The bidirectional screw 5 is rotatably connected to the workbench 1. Two sliders 6 are provided. The two sliders 6 are slidably connected to the workbench 1. The two sliders 6 are threadedly connected to the bidirectional screw 5. The two sliders 6 are fixedly connected to the two mounting frames 2. The motor 7 is fixedly connected to the workbench 1. The output end of the motor 7 is fixedly connected to the bidirectional screw 5. Four clamping frames 8 are provided. A clamping frame 8 is fixedly connected to both sides of each mounting frame 2. When the clamping mechanism clamps the pump casing, the motor 7 is started, driving the bidirectional screw 5 to rotate, thereby driving the two sliders 6 to move toward or away from each other, thereby driving the two parts of the clamping device to approach and clamp the pump casing.

[0048] Secondly, the adjustment clamping assembly includes an adjustment frame 9, a slide 10, a vertical clamping member, a matching box 11, and a spring telescopic rod 12. There are multiple adjustment frames 9, and five adjustment frames 9 are slidably connected in each mounting frame 2. Multiple spring telescopic rods 4 are fixedly connected between every two adjacent adjustment frames 9. There are multiple slides 10, and each slide 10 has an adjustment frame 9. Multiple vertical clamping members are installed on the mounting frame 2. There are two matching boxes 11, and the two matching boxes 11 are respectively fixedly connected to the two mounting frames 2. There are multiple spring telescopic rods 12, and multiple A spring telescopic rod 12 is fixedly connected between the clamping block 3 and the matching box 11. When the clamping assembly is adjusted to work, the pump casing is firstly fixed in the center of the workbench 1. As it is pressed, the protruding part of the pump casing presses down the spring telescopic rod 12 connected to the clamping block 3, so that the contact between the pump casing and the clamping block 3 is closer. Then the vertical pressing member is started to press down the adjusting frame 9, so that the clamping block 3 in the adjusting frame 9 fits the shape of the pump casing more closely, thereby stably clamping the pump casing. At the same time, since the pump casing is clamped only from two directions, the clamped pump casing also has the advantage of easy installation and removal.

[0049] Again, the positioning assembly includes a positioning table 13, a rotating table 14, a threaded rod 15 and a motor 2 16. The positioning table 13 is slidably connected to the workbench 1, the rotating table 14 is rotatably connected to the positioning table 13, the threaded rod 15 is rotatably connected to the workbench 1, the positioning table 13 is threadedly connected to the threaded rod 15, the motor 2 16 is fixedly connected to one side of the workbench 1, and the output end of the motor 2 16 is fixedly connected to the threaded rod 15. When the pump casing is placed on the workbench 1, due to the irregular shape of the pump casing, it will fall over without manual support. Therefore, the pump casing is placed on the rotating table 14, and the pump casing is not easy to fall over. At this time, the clamping mechanism can be directly started to clamp the pump casing well. After clamping is completed or when the positioning assembly is not needed, the motor 2 16 is started. The motor 2 16 drives the threaded rod 2 18 to rotate, and the positioning table 13 threadedly connected thereto can be removed, which has strong selectivity.

[0050] Among them, the vertical clamping member includes a mounting plate 17, a threaded rod 18, a motor 19 and a clamping block 20. There are four mounting plates 17, and two mounting plates 17 are fixedly connected on both sides of each mounting frame 2. There are four threaded rods 18, and each mounting plate 17 is rotatably connected to a threaded rod 18. There are four motors 19, and the four motors 19 are respectively fixedly connected to the tops of the four mounting plates 17. The output ends of the four motors 19 are respectively fixedly connected to the four threaded rods 18. There are four clamping blocks 20, and two of the four clamping blocks 20 are a group. There are two groups of clamping blocks 20, which are respectively fixedly connected to the two topmost adjusting frames 9. The four clamping blocks 20 are threadedly connected to the four threaded rods 2 18. The vertical clamping member is used to clamp several adjusting frames 9 in a loose state. First, start the motor 3 19. The motor 3 19 drives the threaded rod 2 18 to rotate, thereby driving the clamping block 20 to rotate, and further drives the adjusting frame 9 to be pressed down. The topmost adjusting frame 9 is pressed down, and under the action of the spring telescopic rod 1 4, several adjusting frames 9 are pressed down at the same time until the pump casing is clamped, so that the vertical fixing effect is better and the pump casing will not move when the water pump is assembled.

[0051] Finally, four limiting claws 21 are provided on the positioning platform 13. The gaps between the four limiting claws 21 can clamp the tubular structure at the bottom end of the pump casing, thereby achieving a good positioning effect.

[0052] In this embodiment, the pump casing is first clamped in the center of the workbench 1 by the positioning table 13 and the four limiting claws 21, and then the motor 1 7 drives the bidirectional screw 5 to rotate, thereby driving the mounting frame 2 and the clamping block 3 thereon to move toward the middle, and preliminarily clamping the pump casing. Then the motor 2 16 drives the threaded rod 2 18 to rotate, driving the clamping block 20 and the adjusting frame 9 to be pressed down, and also applying a clamping force on the pump casing in the vertical direction, thereby achieving a better clamping and fixing effect, and effectively preventing the pump casing from moving during the processing, which causes the accuracy of the water pump to decrease, thereby affecting the quality of the water pump.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
