[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] Preferred embodiments of the present invention will now be further described with reference to the accompanying drawings, in conjunction with... Figures 1 to 7 As shown, the pump body testing equipment includes a workbench 10. A test fixture 20 and a pump body assembly 30 are provided at one end of the workbench 10. The pump body assembly 30 and the test fixture 20 are detachably connected. A first translation mechanism 40 is provided at the bottom of the test fixture 20. The first translation mechanism 40 is used to drive the test fixture 20 to move along the workbench 10. The pump body assembly 30 includes a body 310 and a drive end 320. The body 310 is installed at one end of the test fixture 20. The drive end 320 passes through the test fixture 20. A drive motor 50 is provided at the other end of the workbench 10. The drive motor 50 has an output end 51. The output end 51 and the drive end 320 are interconnected through a spindle 60.

[0023] In the working state of this application, the test fixture 20 is first moved to one end of the workbench 10 by the first translation mechanism 40. Then, the pump body assembly 30 is moved to the side of the test fixture 20 by the trolley, and its body 310 is detachably fixed to one side of the test fixture 20. At the same time, its drive end 320 passes through the test fixture 20 and faces to the other side. Then, the first translation mechanism 40 is activated to drive the test fixture to move along the workbench 10 to the middle section, so that it is connected to the output end 51 of the drive motor 50. Finally, the drive motor 50 is activated to drive the output end 51 and the drive end 320 to rotate synchronously, thereby simulating the operating state inside the body 310, thereby realizing the test of the pump body.

[0024] Compared with the prior art, this application uses a test fixture 20 to detachably fix the pump body assembly 30, and then uses the first translation mechanism 40 to connect the machine body 310 with the drive motor 50. The drive motor 50 drives the machine body 310 to operate, thereby simulating the operating state inside the machine body 310 and thus realizing the test of the pump body. The whole process is completed automatically without manual intervention, which greatly improves the testing efficiency.

[0025] Further, based on the above embodiments, the test fixture 20 includes a support assembly 100, a support plate 200 is vertically fixed on one side of the support assembly 100, a through groove 210 is provided in the middle of the support plate 200, the body 310 is located on the side of the support plate 200 away from the support assembly 100, and a connecting plate 330 protrudes outward around the body 310. When the body 310 is assembled with the support plate 200, the drive end 320 passes through the through groove 210, and the connecting plate 330 contacts the support plate 200. At least two clamping devices 400 are provided on the support plate 200. The clamping devices 400 are arranged diagonally around the connecting plate 330, and the clamping devices 400 are used to press the connecting plate 330 onto the support plate 200. First, the machine body 310 is installed on the support plate 200, so that its driving end 320 passes through the through groove 210, and the connecting plate 330 contacts the support plate 200. Then, the clamping device 400 is activated to press the connecting plate 330 onto the support plate 200, thereby pressing the machine body 310 assembly onto the support plate 200. This reduces the time for fixing the pump body and the bracket assembly 100 from more than 10 minutes to 1 minute, greatly improving the efficiency of detachable fixing and making operation convenient.

[0026] Further, based on the above embodiments, the clamping device 400 includes a hydraulic cylinder 410, a rotating shaft 420 is provided at one end of the hydraulic cylinder 410, and a pressure plate 430 is sleeved on the rotating shaft 420. The hydraulic cylinder 410 can control the pressure plate 430 to rotate around the rotating shaft 420 as the axis. Normally, the hydraulic cylinder 410 controls the pressure plate 430 to rotate to the vertical direction. At this time, the pressure plate 430 and the connecting plate 330 are not in the same position. When it is necessary to fix the machine body 310 and the support plate 200, the drive end 320 passes through the through groove 210, the connecting plate 330 contacts the support plate 200, and then the rotating shaft 420 is started to drive the pressure plate 430 to rotate, so that the pressure plate 430 rotates to the horizontal position, so that the pressure plate 430 and the connecting plate 330 are in the same position. Then the hydraulic cylinder 410 is driven to drive the pressure plate 430 to tighten towards the support plate 200, so that the connecting plate 330 is pressed on the support plate 200.

[0027] Further, based on the above embodiments, a baffle 220 is provided on the support plate 200, and the through groove 210 is provided on the baffle 220. When the machine is assembled with the support plate 200, the drive end 320 passes through the through groove 210, and the connecting plate 330 contacts the baffle 220. Since the baffle 220 is located between the connecting plate 330 and the support plate 200, the baffle 220 effectively increases the thickness of the support plate 200. When the pump body vibrates during testing, the risk of the machine body 310 detaching from the support plate 200 can be reduced. Preferably, the bracket assembly 100 includes a base plate 110, and support frames 120 are installed on both sides of the base plate 110. The support plate 200 is fixed to one side of the support plate 200.

[0028] Furthermore, based on the above embodiment, a controller 130 is installed on the support frame 120, and a first oil pipe 140 is connected to the other end of the hydraulic cylinder 410. The first oil pipe 140 and the controller 130 are interconnected. The controller 130 is used to control the start and stop of the hydraulic cylinder 410.

[0029] Further, based on the above embodiments, a first threaded hole 221 is provided on the baffle 220, and a second threaded hole 331 corresponding to the position of the first threaded hole 221 is provided on the connecting plate 330. When the connecting plate 330 contacts the support plate 200, a screw (not shown in the figure) can be used to pass through the first threaded hole 221 and the second threaded hole 331 in advance to simply connect the connecting plate 330 and the baffle 220 (without tightening). This allows the operator to leave. Then, the rotating shaft 420 is started to drive the pressure plate 430 to rotate, so that the pressure plate 430 rotates to the horizontal position. Then, the hydraulic cylinder 410 is driven to drive the pressure plate 430 to tighten towards the support plate 200, so that the connecting plate 330 is pressed against the support plate 200. This can prevent the pressure plate 430 from contacting the operator during rotation, thus avoiding safety hazards.

[0030] Further, based on the above embodiment, the first translation mechanism 40 includes a first guide rail 41 laid along the worktable 10, a first sliding seat 42 mounted on the first guide rail 41, the first sliding seat 42 being fixed to the bottom of the test fixture 20, and a lead screw 43 disposed between the first guide rails 41, one end of the lead screw 43 being sleeved with a connecting seat 44, the connecting seat 44 being disposed at the bottom of the test fixture 20. When it is necessary to drive the test fixture 20 to move, it is only necessary to drive the lead screw 43 to rotate, thereby driving the connecting seat 44 to move, and in turn driving the first sliding seat 42 to move along the first guide rail 41.

[0031] Furthermore, based on the above embodiment, a support device 70 is sleeved on the main shaft 60. The support device 70 includes a support base 71, and a support ring 72 is provided on the top of the support base 71. The support ring 72 is sleeved on the main shaft 60. The support device 70 is used to provide support for the middle part of the main shaft 60, thereby further improving the stability of the main shaft 60 during rotation.

[0032] Furthermore, based on the above embodiment, an oil pump 80 is provided on the top of the support device 70, and a control valve 81 connected to it is provided on one side of the oil pump 80 body. A second oil pipe 82 is provided at one end of the control valve 81, and the second oil pipe 82 is connected to the controller 130. The oil pump 80 is used to supply hydraulic oil to the controller 130 and the hydraulic cylinder 410 through the control valve 81 to ensure that the hydraulic cylinder 410 can work normally.

[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.
