Technical Field

[0001] The invention belongs to the technical field of verticality detection, in particular to a device for detecting the verticality of a hydraulic pump blade notch. Background Art

[0002] Hydraulic pumps, as a hydraulic power source, are often used in various production processes. Vane pumps, as an important type of hydraulic pumps, have a close relationship between their operating efficiency, reliability and lifespan and their design. The blade notch is particularly important in the design of the vane pump, because the verticality and shape of the notch directly affect the degree of fit between the blade and the rotor, and thus affect the overall performance of the hydraulic pump.

[0003] In the prior art, some solutions have been proposed for detecting the verticality of the blade slot. For example, the blade slot is detected by a verticality tester. During this process, the user needs to fix the rotor to be tested on the tray of the verticality tester, and then bring the probe of the dial indicator into contact with the surface of the object to be tested, and then slowly move the dial indicator and its probe so that the probe scans the entire blade slot, thereby obtaining the verticality data of the blade slot.

[0004] In the prior art, when inspecting the verticality of blade notches of multiple rotors, the user can only inspect the workpieces to be inspected one by one. During this process, the user needs to perform installation and disassembly multiple times, which affects the inspection efficiency.

[0005] To this end, the present invention provides a device for detecting the verticality of a hydraulic pump blade notch. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a hydraulic pump blade notch verticality detection device described in the present invention comprises a base; the top surface of the base is rotatably connected to a tray, and the tray is driven by a servo motor; the top surface of the tray is fixedly connected to a three-jaw chuck; the top surfaces of the three clamping jaws of the three-jaw chuck are fixedly connected to a bottom bracket; the top surface of the bottom bracket is fixedly connected to a clamping rod; the surface of the clamping rod is slidably connected to a plurality of evenly arranged support plates; the plurality of support plates are fixed to the surface of the clamping rod by a locking assembly; a pair of symmetrically arranged columns are installed on the top surface of the base on both sides of the tray; the surfaces of the two columns are slidably connected to a moving seat, and the moving seat is driven by a servo motor; the ends of the two moving seats that are close to each other are rotatably connected to a rotating seat; the ends of the rotating seat that are away from the moving seat are fixedly connected to an electric push rod; the telescopic end of the electric push rod is rotatably connected to an electronic dial indicator; the electronic dial indicator is connected to an external microcomputer; the external microcomputer processes and displays the measurement data of the electronic dial indicator;During operation, in order to improve the verticality detection of the blade notches of batch rotors, the embodiment of the present invention can be used. First, the user needs to put the central hole of the rotor to be detected on the outside of the clamping rod, and make them located on the top surface of the bottom bracket and the support plate in sequence. Then, the user drives the bottom bracket, the clamping rod and the support plate to move away from the center of the three-jaw chuck through the three-jaw chuck, and finally makes the clamping rod tightly press against the inner wall of the central hole of the rotor, thereby fixing the rotor. Then, the user moves the columns on both sides of the tray to make them close to the blade slot on the surface of the rotor. Then, the user Then adjust the electric push rod at the end of the rotating seat so that the probe of the electronic dial gauge at its end can be inserted into the blade slot, and then the user rotates the electronic dial gauge so that its probe finally rests on the blade slot notch. Then the mobile seat drives the electronic dial gauge from top to bottom to traverse the blade slot of each rotor, thereby obtaining the verticality data of the blade slot, and transmitting it to the external microcomputer for processing and display on the display screen. After the electronic dial gauges on both sides have measured the verticality of the blade slot on each side of the rotor from top to bottom, the user needs to rotate the rotating seat so that The electronic dial indicator rotates 180 degrees, so that the probe of the electronic dial indicator can contact the other side of the rotor blade slot, and then the electronic dial indicator completes the detection of each rotor blade slot from bottom to top. Then the user moves the two columns away from each other, and the probe of the electronic dial indicator is separated from the rotor blade slot. Then the tray rotates, thereby driving the rotor to be detected to rotate together, and the next undetected blade slot is rotated to the corresponding position of the electronic dial indicator. Then the user moves the two columns again to make them close to each other, so that the probe of the electronic dial indicator can contact the blade slot that has not been detected, and repeats the previous operation until all blade slots on the rotor surface are detected. Through the setting of the clamping rod, the bottom bracket and the support plate, the electronic dial indicator can detect the blade slots of multiple rotors from top to bottom and from bottom to top in sequence, thereby realizing batch detection of the blade slots of multiple rotors and improving the detection efficiency.

[0040] like Figures 8 to 10 As shown, a limiting groove 27 is provided on the top surface of the tray 2 at a position corresponding to the receiving groove 24; the limiting groove 27 is matched with the straight plate 26, and the limiting groove 27 is connected to the receiving groove 24; an extension groove 28 is provided on the bottom of the receiving groove 24 at a position corresponding to the connecting rod 25; the extension groove 28 is slidably connected with the connecting rod 25, and the connecting rod 25 is matched with the extension groove 28; during operation, when the diameter of the rotor is smaller than that of the tray 2, the user can slide the straight plate 26 and the connecting rod 25 so that the connecting rod 25 is inserted into the extension groove, and the straight plate 26 will also be inserted into the limiting groove 27, at which time the straight plate 26 can be located on the top surface of the tray 2 and correct the rotor that is smaller than the diameter of the tray 2.

[0041] like Figures 8 to 10 As shown, a slide plate 29 is slidably connected to one side of the straight plate 26 close to the connecting rod 25; side plates 30 are fixedly connected to both sides of the slide plate 29, and the straight plate 26 is located between the two side plates 30; the end surface of the side plate 30 away from the straight plate 26 is flush with the surface of the side of the straight plate 26 away from the slide plate 29; during operation, when detecting rotors of different thicknesses, the user can slide the slide plate 29 to extend the length of the straight plate 26, thereby adapting to rotors of different thicknesses. At the same time, the side plates 30 on both sides of the slide plate 29 are also flush with the slide plate 29, which can also ensure the accuracy of correction.

[0042] like Figures 8 to 10 As shown, a buckle plate 31 is rotatably connected between the two side plates 30 and at one end away from the straight plate 26; a baffle plate 32 is fixedly connected to one end of the two side plates 30 close to the buckle plate 31; the straight plate 26 is made of magnetizable metal; a magnet sheet 33 is fixedly connected to one end of the buckle plate 31 away from the rotational connection between the buckle plate 31 and the side plate 30; during operation, when the straight plate 26, the slide plate 29 and the side plate 30 need to be stored in the storage slot 24, the user needs to screw the buckle plate 31 so that the magnet sheet 33 at the end of the buckle plate 31 is adsorbed on the end surface of the straight plate 26 On, the straight plate 26 and the slide plate 29 are fixed, so that the straight plate 26, the slide plate 29 and the side plate 30 can be easily stored in the storage groove 24. When correcting the rotor, the user can rotate the buckle plate 31 so that one side of the buckle plate 31 is attached to the surface of the baffle 32, so that the buckle plate 31 and the slide plate 29 are perpendicular. At this time, the user can buckle the buckle plate 31 on the top surface of the rotor, so as to fix the straight plate 26 and the slide plate 29, so that the user does not have to hold the straight plate 26 and the slide plate 29 all the time, which is convenient for the user to correct the rotor.

[0043] During operation, in order to improve the verticality detection of the blade notches of batch rotors, the embodiment of the present invention can be used. First, the user needs to put the central hole of the rotor to be detected on the outside of the clamping rod 5, and make them located on the top surfaces of the bottom bracket 4 and the support plate 6 in sequence. Then, the user drives the bottom bracket 4, the clamping rod 5 and the support plate 6 to move away from the center of the circle of the three-jaw chuck 3 through the three-jaw chuck 3, and finally makes the clamping rod 5 tightly press against the inner wall of the central hole of the rotor, thereby fixing the rotor. Then, the user moves the columns 7 on both sides of the tray 2 to make them close to the blade slots on the surface of the rotor, and then the user moves Adjust the electric push rod 10 at the end of the rotating seat 9 so that the probe of the electronic dial gauge 11 at its end can be inserted into the blade slot, and then the user rotates the electronic dial gauge 11 so that its probe finally rests on the blade slot notch. Then the mobile seat 8 drives the electronic dial gauge 11 from top to bottom to traverse the blade slot of each rotor, thereby obtaining the verticality data of the blade slot, and transmitting it to the external microcomputer for processing and displaying it on the display screen. After the electronic dial gauges 11 on both sides have measured the verticality of the blade slot of each rotor side from top to bottom, the user needs to rotate the rotating seat 9 so that The electronic dial gauge 11 is rotated 180 degrees, so that the probe of the electronic dial gauge 11 can contact the other side of the rotor blade slot, and then the electronic dial gauge 11 completes the detection of each rotor blade slot from bottom to top, and then the user moves the two columns 7 away from each other, and the probe of the electronic dial gauge 11 is separated from the rotor blade slot, and then the tray 2 is rotated, thereby driving the rotor to be detected to rotate together, and the next undetected blade slot is rotated to the corresponding position of the electronic dial gauge 11, and then the user moves the two columns 7 again to make them close to each other, so that The probe of the electronic dial indicator 11 can contact the blade slot notch that has not been detected, and repeat the previous operation until all the blade slots on the rotor surface are detected. Through the arrangement of the clamping rod 5, the bottom support 4 and the support plate 6, the electronic dial indicator 11 can detect the blade slots of multiple rotors from top to bottom and from bottom to top in sequence, thereby realizing batch detection of the blade slots of multiple rotors and improving the detection efficiency. Two electronic dial indicators 11 are arranged on both sides of the tray 2, so that each rotor can detect two blade slots at the same time, thereby further improving the detection efficiency and shortening the detection time.

[0044] When the user needs to detect rotor blade slots of different thicknesses, the user can screw the threaded rod 13 to drive the scissors-type telescopic frame 12 to extend or shorten. Since the support plates 6 are evenly fixed to the hinge points in the scissors-type telescopic frame 12, the spacing between all support plates 6 can always remain consistent, making it convenient for the user to synchronously adjust multiple support plates 6 and avoiding manual adjustments one by one. This not only improves the user's adjustment efficiency, but also reduces the user's difficulty of use, thereby improving the usability of the embodiment of the present invention.

[0045] Before the rotor is placed on the top surface of each support plate 6, the user can first rotate the extension plate 15 to make it vertical, thereby facilitating the central hole of the rotor to pass smoothly through the support plate 6. When the rotor needs to be placed on the top surface of a certain layer of support plate 6, the user rotates the extension plate 15 again to make it rotate from a vertical state to a horizontal state. Then the rotor can be placed on the extension plate 15 first, and then the three-jaw chuck 3 drives the clamping plate to squeeze the inner wall of the central hole of the rotor, thereby driving the support plate 6 to move so that it can also contact and support the bottom of the rotor, thereby facilitating the user to install the rotor. At the same time, the support seat 14 at the bottom of the support plate 6 can also provide support for the support plate 6 and the extension plate 15 to prevent them from bending or breaking.

[0046] When the user needs the two columns 7 to move closer to or farther away from each other, the user can use the servo motor to drive the column 7 on one side to move along the slide groove 16, and the column 7 on this side will drive the gear 17 to rotate through the tooth plate 18 fixed thereto, and the rotating gear 17 will drive the tooth plate 18 on the other side to move, thereby achieving driving one column 7 to drive the column 7 on the other side to move synchronously, thereby facilitating the user to synchronously adjust the columns 7 on both sides.

[0047] After the electronic dial gauge 11 has detected the blade notch of each rotor from top to bottom, the column 7 will first move away from the tray 2, so that the probe of the electronic dial gauge 11 can leave the surface of the three-jaw chuck 3, and then the moving seat 8 will continue to descend, so that the gear 22 will be lowered to a height that can engage with the tooth plate 2 19, and then the column 7 will continue to move away from the tray 2, and the gear 22 will contact with the tooth plate 2 19, and then the gear 22 will roll on the surface of the tooth plate 2 19. At this time, the inner ring and the outer ring of the one-way bearing 21 will rotate synchronously, and the gear 22 can drive the rotating rod 20 to rotate, and the rotating rod 20 can rotate through the gear The group drives the rotating seat 9 to rotate 180 degrees, so that the electronic dial indicator 11 can detect the other side of the blade notch, and then the two columns 7 move toward each other. At this time, the rotation direction of gear 22 is opposite to that before, so that the inner ring and outer ring of the one-way bearing 21 will not rotate synchronously, but will rotate relative to each other. Therefore, the rotating rod 20 will not rotate with gear 22, so the electronic dial indicator 11 can maintain its position and contact with the blade notch. Through the cooperation of gear 22 and tooth plate 2 19, the user no longer needs to manually adjust the direction of the probe of the electronic dial indicator 11 after detecting the blade notch on one side.

[0048] When gear 22 is separated from tooth plate 2 19, if the rotation angle of the rotating base 9 is less than 180 degrees, the edge of the rotating base 9 will squeeze the spring piece 23. At this time, the spring piece 23 is squeezed and drives the rotating base 9 to continue rotating, so that the rotating base 9 completes a 180-degree rotation and makes the vertical surfaces on both sides of the rotating base 9 fit against the surface of the spring piece 23, thereby avoiding slippage between tooth plate 2 19 and gear 22, which causes the rotating base 9 to fail to rotate 180 degrees correctly.

[0049] After the user places the rotors on the top surface of the support plate 6 in sequence, the user can pull out the connecting rod 25 in the storage groove 24 and rotate the straight plate 26 to make it vertical, and then make the inner wall of one side of the rotor blade groove fit to the surface of the straight plate 26, so that the blade grooves of each rotor are all aligned, which is convenient for the electronic dial indicator 11 to detect them.

[0050] When the diameter of the rotor is smaller than that of the tray 2, the user can slide the straight plate 26 and the connecting rod 25 so that the connecting rod 25 is inserted into the extension slot, and the straight plate 26 is also inserted into the limiting slot 27. At this time, the straight plate 26 can be located on the top surface of the tray 2 and correct the rotor that is smaller than the diameter of the tray 2.

[0051] When testing rotors of different thicknesses, the user can slide the slide plate 29 to extend the length of the straight plate 26 to adapt to rotors of different thicknesses. At the same time, the side plates 30 on both sides of the slide plate 29 are also flush with the slide plate 29, which can also ensure the accuracy of correction.

[0052] When the straight plate 26, the skateboard 29 and the side plate 30 need to be stored in the storage groove 24, the user needs to screw the buckle plate 31 so that the magnet sheet 33 at the end of the buckle plate 31 is adsorbed on the end surface of the straight plate 26, thereby completing the fixation between the straight plate 26 and the skateboard 29, and then facilitating the storage of the straight plate 26, the skateboard 29 and the side plate 30 in the storage groove 24. When correcting the rotor, the user can rotate the buckle plate 31 so that one side of the buckle plate 31 is attached to the surface of the baffle 32, thereby making the buckle plate 31 perpendicular to the skateboard 29. At this time, the user can buckle the buckle plate 31 on the top surface of the rotor, thereby fixing the straight plate 26 and the skateboard 29, so that the user does not have to hold the straight plate 26 and the skateboard 29 all the time, thereby facilitating the user to correct the rotor.
