Description

Technical Field

[0002] A pump is a machine that transports fluid or pressurizes fluid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. The pump input and output ports have end faces with connecting holes on them. The end faces are connected to other parts through flanges, etc. The flange shoulder is matched with the inner wall of the connecting hole. Therefore, the inner wall of the pump end face connecting hole has size requirements to meet the coaxiality requirements of the shaft on the flange. Therefore, it is necessary to measure the aperture size of the pump end face connecting hole. The existing coaxiality detection equipment is to contact the dial indicator head with the inner wall of the hole, rotate the pump body or rotate the dial indicator, and detect whether the radial runout of the inner diameter meets the requirements.

[0043] like Figure 7 , Figure 8 As shown, a balancing hole 51 is provided on the upper end surface of the regulating tube 24 .

[0044] like Figure 5 As shown, a gear groove 53 is provided at the lower end of the rotating arm 16 , and the transmission gear 12 is installed in the gear groove 53 .

[0045] like Fig. 9 , Fig.10 , Fig.11 As shown, under the action of compression spring 1 44 and compression spring 2 45 , the inner ends of marking pen 1 46 and marking pen 2 47 are always in contact with the outer wall of rotating disk 42 , and the outer edge of roller 50 exceeds the outer ends of marking pen 1 46 and marking pen 2 47 .

[0046] like Figure 7 , Figure 8 As shown, the adjusting sleeve 25 and the adjusting tube 24 are made of transparent material.

[0047] When in use, the center column 10 is moved up and down, the center column 10 drives the transmission rack 11 up and down, the transmission rack 11 drives the transmission gear 12 to rotate, the transmission gear 12 drives the linkage shaft 13 to rotate, the linkage shaft 13 drives the rotating arm 16 to rotate, the rotating arm 16 drives the rotating arm 2 17 to rotate, the rotating arm 2 17 drives the adjustment block 18 to slide in the adjustment groove 3, the adjustment block 18 drives the installation sleeve 21 to move in the adjustment groove 3, the installation sleeve 21 drives the installation threaded rod 22 to move, so that the installation threaded rod 22 is aligned with the threaded hole on the end face of the pump body, and then the tightening handle 23 is turned to rotate the installation threaded rod 22 to enter the threaded hole on the end face of the pump body;

[0048] Initially, the space between the support sleeve 27 and the piston 30 is filled with hydraulic oil, and a certain height of hydraulic oil is filled in the adjusting tube 24. Then, according to the size of the inner wall of the connecting hole on the end face of the pump body, the support sleeve 27 is pressed, and the support sleeve 27 moves on the piston 30. The scale line 52 is observed to make the distance between the center line of the adjusting tube 24 and the outer edge of the roller 50 the same as the inner diameter of the connecting hole on the end face of the pump body. During this adjustment process, the support sleeve 27 squeezes the adjusting spring 29, and the size of the space between the piston 30 and the support sleeve 27 changes with the movement of the support sleeve 27, thereby changing the height of the hydraulic oil in the adjusting tube 24. The hydraulic oil drives the buoyancy block 28 to remain stationary at a certain height, and then the adjusting sleeve is rotated relative to the adjusting tube 24. 25, the adjusting sleeve 25 moves on the adjusting tube 24, the adjusting sleeve 25 drives the connecting rod 26 to move, the connecting rod 26 drives the upper contact piece 33 and the lower contact piece 32 to move, so that the adjusting mark 36 on the connecting rod 26 is flush with the upper surface of the buoyancy block 28, at this time the buoyancy block 28 is just in the middle of the upper contact piece 33 and the lower contact piece 32, the adjusting tube 24 is moved up and down, the adjusting tube 24 drives the supporting sleeve 27 and the roller 50 to move up and down, the supporting sleeve 27 is released, under the action of the elastic force of the adjusting spring 29, the supporting sleeve 27 drives the roller 50 to press on the inner wall of the connecting hole of the end face of the pump body, and then the adjusting tube 24 is rotated together, the adjusting tube 24 drives the piston 30 and the supporting sleeve 27 to rotate around the axis of the adjusting tube 24;

[0049] In the initial state, the protrusion 43 is between the marking pen 1 46 and the marking pen 2 47. When the upper contact piece 33 and the upper conductive piece 34 are connected, the controller controls the conversion motor 39 to rotate counterclockwise. When the upper contact piece 33 and the upper conductive piece 34 are disconnected, the controller controls the conversion motor 39 to rotate clockwise. When the lower contact piece 32 and the lower conductive piece 35 are connected, the controller controls the conversion motor 39 to rotate clockwise. When the lower contact piece 32 and the lower conductive piece 35 are disconnected, the controller controls the conversion motor 39 to rotate clockwise and counterclockwise.

[0050] When the inner wall size of the pump body end face connection hole meets the requirements, that is, in the initial state, the protrusion 43 is between the marking pen 1 46 and the marking pen 2 47. At this time, the ends of the marking pen 1 46 and the marking pen 2 47 are lower than the outer wall of the roller 50, so the inner wall of the pump body end face connection hole will not be marked.

[0051] When the inner wall size of the connecting hole on the end face of the pump body is too large, the adjusting spring 29 pushes the supporting sleeve 27 outward, the space between the supporting sleeve 27 and the piston 30 becomes larger, and the hydraulic oil in the adjusting tube 24 enters from the connecting hole 37 between the supporting sleeve 27 and the piston 30. The liquid level of the hydraulic oil in the adjusting tube 24 drops, and the buoyancy block 28 drops. When it drops to the set value, the lower conductive sheet 35 contacts the lower contact sheet 32, and the signal receiver transmits the signal to the controller. The controller controls the conversion motor 39 to rotate clockwise by a certain angle, and the conversion motor 39 drives the rotating shaft 41 to rotate, and the rotating shaft 41 drives the protrusion 43 to rotate clockwise by a certain angle. At this time, the protrusion 43 pushes the marking pen 2 47 outward, and the marking pen 2 47 marks the inner wall of the connecting hole on the end face of the pump body that is too large.

[0052] When the inner wall size of the connecting hole on the end face of the pump body is too small, the inner wall of the connecting hole pushes the support sleeve 27 inward, and the space between the support sleeve 27 and the piston 30 becomes smaller. The hydraulic oil between the support sleeve 27 and the piston 30 enters the adjusting tube 24 from the connecting hole 37, and the liquid level of the hydraulic oil in the adjusting tube 24 rises, and the buoyancy block 28 rises. When it rises to the set value, the upper conductive sheet 34 and the upper contact sheet 33 contact, and the signal receiver transmits the signal to the controller. The controller controls the conversion motor 39 to rotate counterclockwise by a certain angle, and the conversion motor 39 drives the rotating shaft 41 to rotate, and the rotating shaft 41 drives the protrusion 43 to rotate counterclockwise by a certain angle. At this time, the protrusion 43 pushes the marking pen 46 outward, and the marking pen 46 marks the inner wall of the connecting hole on the end face of the pump body that is too small.
