[0021] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0022] The preferred embodiments of the present invention will now be further described with reference to the accompanying drawings, such as... Figure 1 As shown, an automatic torque tightening device for pump body screws includes a workbench 100. A pump body assembly 200 is disposed on the top of the workbench 100. Clamping mechanisms 300 are disposed on both sides of the pump body assembly 200. The clamping mechanisms 300 are used to clamp and fix the pump body assembly 200 on the top of the workbench 100. The pump body assembly 200 includes a cylindrical first cavity 210. A first cover plate 220 is covered at one end of the first cavity 210. A plurality of first screws 230 are disposed between the first cover plate 220 and the first cavity 210 and fixed to each other. A tightening mechanism 400 is disposed on one side of the workbench 100. The tightening mechanism 400 fixes the first cover plate 220 and the first cavity 210 to each other through the first screws 230.

[0023] This application pertains to auxiliary equipment in a pump production line, primarily used for tightening large-diameter screws on the pump body. In operation, the pump body assembly 200 is first placed on top of the workbench 100 using a crane. Then, the clamping mechanism 300 clamps and fixes the pump body assembly 200 to the top of the workbench 100. The operator then operates the tightening mechanism 400 to align the first screw 230 between the first cover plate 220 and the first cavity 210, fitting it around the first screw 230. The tightening mechanism 400 is then activated to rotate the first screw 230, thereby tightening and fixing the first cover plate 220 and the first cavity 210 together. It should be noted that in this application, the top of the tightening mechanism 400 can be connected to a crane or a robotic arm (not shown in the figure), allowing for operation by the operator.

[0024] Compared with the prior art, this application provides a tightening mechanism 400 on one side of the workbench 100, which allows the operator to fix the large-diameter screw between the first cover plate 220 and the first cavity 210 on the pump body by controlling the tightening mechanism 400. This saves the operator's physical strength and improves safety. In addition, it further improves the safety of pump body production.

[0025] Furthermore, based on the above embodiments, such asFigure 2 As shown, a guide rail 110 is provided on the worktable 100, and a sliding seat 120 is mounted on the top of the guide rail 110. The sliding seat 120 can move along the guide rail 110. A first propulsion cylinder 130 is provided on the worktable 100, and the drive end of the first propulsion cylinder 130 is fixedly connected to the sliding seat 120. The clamping mechanism 300 is located on the top of the sliding seat 120. Thus, when the crane places the pump body assembly 200, the position of the sliding seat 120 can be controlled by activating the first propulsion cylinder 130, so that the clamping mechanism 300 can better align and clamp the pump body assembly 200.

[0026] Furthermore, based on the above embodiments, such as Figure 2 As shown, the clamping mechanism 300 includes a fixed plate 310 and a movable plate 320 facing each other. The fixed plate 310 is fixed to the top of the sliding seat 120. A second propulsion cylinder 330 is provided on the side of the movable plate 320 away from the fixed plate 310, and the driving end of the second propulsion cylinder 330 is fixedly connected to the movable plate 320. When the pump body assembly 200 is located between the fixed plate 310 and the movable plate 320, the second propulsion cylinder 330 is activated to push the movable plate 320 toward the fixed plate 310, thereby clamping and fixing the pump body assembly 200 to the top of the sliding seat 120.

[0027] Furthermore, based on the above embodiments, such as Figure 3 As shown, the tightening mechanism 400 includes a rotary motor 410, a sleeve 420 fixed to one side of the rotary motor 410, and a hollow rotating shaft 430 disposed inside the sleeve 420. The drive end of the rotary motor 410 is connected to the rotating shaft 430. When it is necessary to fix the first cover plate 220 and the first cavity 210, the tightening mechanism 400 is first moved to a preset position by a crane or a robotic arm (not shown in the figure), the rotating shaft 430 is sleeved around the first screw 230, and then the rotary motor 410 is started to drive the rotating shaft 430 to rotate, thereby driving the first screw 230 to rotate, and thus tightening and fixing the first cover plate 220 and the first cavity 210 together.

[0028] Furthermore, based on the above embodiments, such as Figure 3 As shown, a support ring 440 is sleeved on the sleeve 420, and a first connecting plate 450 is fixed to the top of the support ring 440. The first connecting plate 450 is used to connect with a crane or a robotic arm (not shown in the figure), thereby facilitating the operator's control of the tightening mechanism 400.

[0029] Furthermore, based on the above embodiments, such as Figure 3As shown, a handle 460 is provided on the side of the support ring 440. When the crane or robot (not shown in the figure) moves the tightening mechanism 400 to the preset position, the operator can use the handle 460 to make fine adjustments to its position, so that the rotating shaft 430 can be better fitted around the first screw 230.

[0030] Furthermore, based on the above embodiments, such as Figure 4 As shown, the pump body assembly 200 further includes a cylindrical second cavity 240, with a second cover plate 250 covering one end of the second cavity 240. A plurality of second screws 260 are arranged between the second cover plate 250 and the second cavity 240 for mutual fixation. The first cavity 210 and the second cavity 240 are connected to each other via a connector 270. Thus, after the first cover plate 220 and the first cavity 210 are fixed together by a tightening mechanism 400, the positions of the first cavity 210 and the second cavity 240 can be flipped, and the second cover plate 250 and the second cavity 240 can be tightened together by the tightening mechanism 400, thereby further improving efficiency.

[0031] Furthermore, based on the above embodiments, such as Figure 4 As shown, the connector 270 includes a second connecting plate 271, which is detachably fixed between the first cover plate 220 and the second cover plate 250. A hanging ring 272 is provided on the top of the second connecting plate 271. In this way, the trolley can be connected to the hanging ring 272, thereby facilitating the placement of the pump body assembly 200 at a preset position on the workbench 100.

[0032] Furthermore, based on the above embodiments, such as Figure 2 As shown, a third connecting plate 340 is also provided between the second propulsion cylinder 330 and the moving plate 320. The third connecting plate 340 is fixed on the sliding seat 120, and the second propulsion cylinder 330 is fixed on the side of the third connecting plate 340 away from the moving plate 320. A pair of guide posts 350 are provided between the third connecting plate 340 and the moving plate 320. When the second propulsion cylinder 330 is activated, it pushes the moving plate 320 toward the fixed plate 310, and the guide posts 350 can guide the movement direction of the moving plate 320.

[0033] The details of the exemplary embodiments described above are provided, and the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the invention.
