Description

Technical Field

[0001] This utility model belongs to the field of plunger processing technology, and specifically relates to a plunger ball head profile inspection device. Background Technology

[0002] A plunger ball head refers to a design where one end of the plunger has a spherical head. This structure allows the plunger to deflect or rotate within a certain range, thus adapting to more complex working environments and application scenarios. Plunger ball heads are widely used in mechanical systems that require flexibility and high precision, such as hydraulic cylinders, syringes, and robot joints. During the processing of plunger ball heads, a ball head contour inspection device is needed to inspect the contour of the plunger ball head.

[0003] Existing plunger ball head profile inspection devices work by placing the plunger ball head to be inspected on a testing table, then controlling a machining and fixing mechanism to fix the plunger ball head in its vertical position. The testing table is then manually rotated, causing the connected plunger ball head to rotate as well. During rotation, the pressure sensor's detection head contacts the outer wall of the plunger ball head, and the profile inspection is achieved by reading the changes in the pressure sensor's parameters. However, in actual use, the uneven rotation speed of the testing table during manual rotation makes it difficult for personnel to accurately observe the changes in the pressure sensor's parameters, resulting in poor profile inspection results for some ball heads. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a plunger ball head profile inspection device, which can quickly and smoothly rotate the plunger ball head with a stable clamp during inspection, thereby facilitating better detection of whether the plunger ball head profile is qualified.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a plunger ball head contour inspection device, including a bracket, a bracket with evenly distributed support feet on its lower surface, a mounting plate on its upper surface, a drive box with symmetrically distributed drive boxes on its lower surface, a turntable rotatably mounted between the drive box and the mounting plate, a pressure detector with symmetrically distributed pressure detectors on its upper surface, the pressure detectors being installed in conjunction with adjacent turntables, an electrical control module for driving the turntables to rotate on the drive box, and a limiting and fixing module for limiting the plunger ball head on the mounting plate; the electrical control module includes a worm gear fixedly sleeved on the outer arc surface of the lower end of the turntable, a worm rotatably mounted inside each drive box, the worm meshing with adjacent worm gears, a motor mounted on each drive box, the output shaft of the motor being fixed to adjacent worms via couplings; and rubber pads are glued and fixed to the lower surface of each support foot.

[0006] As a further improvement of this utility model, the limiting and fixing module includes guide rails symmetrically arranged on the upper surface of the mounting plate. Each guide rail has a sliding seat slidably arranged inside it. Each sliding seat has a uniformly distributed rotating shaft rotatably arranged inside it. Symmetrically distributed rotating rods are fixedly sleeved on the outer arc surface of each rotating shaft. The end of each rotating rod on the same side away from the rotating shaft is rotatably connected to a pressure table. A rotating platform is rotatably arranged on the lower surface of each pressure table. A position adjustment unit for adjusting the horizontal position of the rotating platform is also provided on the guide rail. A downward pressure control unit for driving the vertical movement of the rotating platform is also provided on the sliding seat. The downward pressure control unit includes a worm gear II fixedly sleeved in the middle of the outer arc surface of the rotating shaft on the lower side. A support is provided at the bottom of each sliding seat. A worm gear II is rotatably arranged between the support and the inner wall of the adjacent sliding seat. The worm gear II is meshed with the adjacent worm gear II. A motor II is provided on each support. The output shaft of the motor II is fixed to the adjacent worm gear II via a coupling.

[0007] As a further improvement of this utility model, the position adjustment unit includes a screw threaded to the rear side of the guide rail, the front end of the screw being rotatably connected to the adjacent sliding seat, and a handwheel being provided at the rear end of each screw.

[0008] As a further improvement of this utility model, a control board is provided on the upper surface of the mounting plate, and the pressure detector, motor one and motor two are all electrically connected to the control board.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, by turning the handwheel, the threaded relationship between the screw and the guide rail causes the sliding seat to slide on the guide rail, thereby causing the sliding seat to move the rotating table and adjusting the horizontal position of the rotating table.

[0011] Secondly, the plunger ball head to be tested is placed on the turntable, and then the motor is controlled by the control board to drive the turntable to press down quickly and stably vertically. Through the cooperation of the turntable and the turntable, the plunger ball head to be tested is quickly and stably limited and fixed.

[0012] Thirdly, by controlling the pressure detector and motor through the control board, the turntable can quickly and stably drive the fixed plunger ball head to rotate at a steady speed. During the rotation, the change in the pressure detector reading is used to detect whether the contour of the plunger ball head is qualified.

[0013] Fourth, during use, the rubber pads glued to the upper surface of the legs can increase the friction between the legs and the ground, thus effectively preventing the support from easily shifting during use. Attached Figure Description

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 1 , 4 As shown, the system includes a bracket 101, with evenly distributed support legs 102 on the lower surface of the bracket 101, a mounting plate 103 on the upper surface of the bracket 101, and symmetrically distributed drive boxes 106 on the lower surface of the mounting plate 103. Turntables 104 are rotatably mounted between the drive boxes 106 and the mounting plate 103. Pressure detectors 105 are symmetrically distributed on the upper surface of the mounting plate 103, and the pressure detectors 105 are respectively installed in conjunction with adjacent turntables 104. An electronic control module for driving the turntables 104 to rotate is also provided on the drive box 106, and a limit fixing module for limiting the movement of the plunger ball head is also provided on the mounting plate 103.

[0022] like Figure 2 , 3As shown, the electrical control module includes a worm gear 107 fixedly sleeved on the outer arc surface of the lower end of the turntable 104, and a worm 108 rotatably installed inside the drive box 106. The worm 108 is meshed with the adjacent worm gear 107 respectively. The drive box 106 is equipped with a motor 109. The output shaft of the motor 109 is fixed to the adjacent worm 108 by a coupling.

[0023] like Figure 2 , 3 As shown, the limiting and fixing module includes guide rails 201 symmetrically arranged on the upper surface of the mounting plate 103. Sliding seats 202 are slidably arranged inside each guide rail 201. Rotating shafts 203 are rotatably arranged inside each sliding seat 202. Symmetrically distributed rotating rods 204 are fixedly sleeved on the outer arc surface of each rotating shaft 203. The ends of the rotating rods 204 located on the same side away from the rotating shafts 203 are rotatably connected to a pressure table 205. A rotating platform 206 is rotatably arranged on the lower surface of each pressure table 205. A position adjustment unit for adjusting the horizontal position of the rotating platform 206 is also provided on the guide rails 201. A downward pressure control unit for driving the vertical movement of the rotating platform 206 is also provided on the sliding seats 202. The pressure control unit includes a worm gear 207 fixedly sleeved on the middle of the outer arc surface of the rotating shaft 203 on the lower side. Each sliding seat 202 has a support 208 at its inner bottom end. A worm gear 209 is rotatably arranged between the support 208 and the inner wall of the adjacent sliding seat 202. The worm gear 209 is meshed with the adjacent worm gear 207. Each support 208 is equipped with a motor 210. The output shaft of the motor 210 is fixed to the adjacent worm gear 209 by a coupling. The position adjustment unit includes a screw 211 threadedly connected to the rear side of the guide rail 201. The front end of the screw 211 is rotatably connected to the adjacent sliding seat 202. Each rear end of the screw 211 is equipped with a handwheel 212.

[0024] like Figure 1 , 2 As shown, a control board 301 is provided on the upper surface of the mounting plate 103, and the pressure detector 105, motor 109 and motor 210 are all electrically connected to the control board 301.

[0025] By rotating the handwheel 212, the operator causes the screw 211 connected to it to rotate. Then, through the threaded relationship between the screw 211 and the guide rail 201, the sliding seat 202 slides on the guide rail 201, which in turn causes the sliding seat 202 to move the rotating table 206, thereby adjusting the horizontal position of the rotating table 206.

[0026] In use, the plunger ball head to be tested is placed on the turntable 104. Then, the control board 301 controls the operation of the motor 210, so that the output shaft of the motor 210 drives the worm gear 209 connected to it to rotate. Then, through the meshing relationship between the worm gear 209 and the worm wheel 207, the worm wheel 207 is driven to rotate. The worm wheel 207 drives the rotating shaft 203 connected to it to rotate. Since the rotating shaft 203, the rotating rod 204 and the pressure table 205 can form a parallelogram structure, the pressure table 205 can be driven to press down quickly and stably vertically, and the rotating table 206 can be driven to press down quickly and stably vertically. Through the cooperation between the rotating table 206 and the turntable 104, the plunger ball head to be tested is quickly and stably limited and fixed.

[0027] The pressure detector 105 and motor 109 are controlled by the control board 301. The output shaft of motor 109 drives the worm gear 108 connected to it to rotate. Then, through the meshing relationship between worm gear 108 and worm wheel 107, the turntable 104 where worm wheel 107 is located is driven to rotate. The turntable 104 can quickly and stably drive the plunger ball head, which is fixed by the limit, to rotate at a steady speed. During the rotation, the change in the reading of pressure detector 105 is used to detect whether the contour of the plunger ball head is qualified.

[0028] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, rubber pads are glued and fixed to the lower surface of the support legs 102. During use, the rubber pads glued and fixed to the lower surface of the support legs 102 can increase the friction between the support legs 102 and the ground, thereby effectively preventing the position of the support 101 from easily moving during use.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
