A square block is fixedly connected to the middle of the top surface of the workbench. A cylindrical rod I is rotatably connected to the square block. Two turntables are fixedly sleeved at both ends of the cylindrical rod I. Two fixing frames I are fixedly connected to the top surface of the workbench. Two limit blocks are fixedly connected to the top surfaces of the two fixing frames I. A cylindrical rod II is rotatably connected to the two limit blocks. Two wheels are fixedly sleeved on the cylindrical rod II. Two frames are fixedly connected to the top surface of the workbench. Two sliding grooves I are opened on the sides of the two frames close to each other. Two sliders I are slidably connected inside the two sliding grooves I. A moving rod is fixedly connected to the sides of the two sliders I close to each other. A T-shaped groove is opened in the middle of the moving rod.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By arranging a cleaning assembly, the operator places the rod body on the top of the positioning plate, starts the electric push rods on both sides. The electric push rods drive the contact plates to move, and the contact plates drive the limiting rods to move. The contact rollers on the two contact plates position the wheel body, keeping the rod body and the wheel body in the central position and positioning through the positioning assembly. Then, the first motor is started. The sliding sleeve slides on the guide rod, and the screw rod part rotates to make the sliding block and the mounting cover move horizontally. The mounting cover drives the collection box to move until the fitting rod fits with the wheel body. At this time, the positioning assembly drives the rod body and the wheel body to rotate. The outer side of the wheel body contacts the fitting rod. The wheel body first drives the fitting rod to rotate, and the fitting rod drives the rotating rod and the torsion spring to rotate. When the elastic force of the torsion spring is greater than the friction force between the fitting rod and the wheel body, the torsion spring drives the rotating rod and the fitting rod to reset, so that the fitting rod can assist in rotating and scraping. The elastic force of the first spring drives the sliding rod and the mounting box to press down, and the mounting box drives the cleaning roller to press tightly on the outer ring of the wheel body. As the wheel body rotates, the cleaning roller is convenient for cleaning the outer ring of the wheel body, and the sundries cleaned fall into the collection box for collection, solving the problem that dust and sundries will accumulate during the operation of the wheel pair, and these impurities will affect the accuracy of laser detection and the precision of subsequent dynamic balance detection; 2. A positioning component is provided. After the rod body and the wheel body are placed in the middle position, by sleeving the top bar and the bottom bar on the upper and lower parts of the rod body respectively, the communication groove fits with the rod body, and the inside of the step groove and the communication groove is in a sealed state, keeping the side rod and the rotating rod spaced apart. When the rotating rod rotates, it can drive the side rod to rotate. The inserting rod passes through the upper block and inserts into the lower block. The inserting rod pulls the pulling bar. Guided by the guiding plate, the pulling bar will drive the top block to rise. The top block drives the upper rod and the piston to rise. The piston compresses the second spring and evacuates the inside of the step groove. The step groove and the communication groove are in a negative pressure state, making the positioning of the top bar and the bottom bar on the rod body more stable. And when the inserting rod descends until the inserting slot contacts the inserting pin, the elastic force of the third spring drives the inserting pin to pop out, and the inserting pin is stuck in the inserting slot, facilitating the positioning of the inserting rod and facilitating the subsequent rotation of the rod body and the wheel body. By starting the second motor, the second motor drives the rotating cylinder and the rotating rod to rotate. The rotating rod drives the side rod to rotate. The side rod, through the top bar and the bottom bar, keeps the rod body and the wheel body rotating stably, facilitating the cleaning of the wheel body. Move the installation cover away, start the linear guide rail, and the linear guide rail drives the installation sleeve and the laser detector to move and detect, solving the problem that when the turntable drives the wheel pair to rotate for detection, slippage may occur between the turntable and the wheel pair, thus reducing the rotational stability of the wheel pair.

One side inner wall of the mounting cover 77 is rotatably installed with a rotating rod 711. One side end of the rotating rod 711 is fixedly connected with a fitting rod 712, and a torsion spring 713 is sleeved on the outside of the rotating rod 711.

[0030] On the lower part of one side of the side plate 2 close to the positioning plate 4, an electric push rod 71 is fixedly installed. The telescopic end of the electric push rod 71 is fixedly connected with a contact plate 72. A contact roller is rotatably installed on the side of the contact plate 72 close to the wheel body 6. A limiting rod 73 is fixedly connected to the side of the contact plate 72 close to the side plate 2, and the limiting rod 73 is slidably connected with the side plate 2.

[0031] On the upper part of one side of the side plate 2 close to the positioning plate 4, a first motor 74 and a guide rod 78 are fixedly installed. The output end of the first motor 74 is fixedly connected with a lead screw part 75. A sliding block 76 is threadedly connected to the outside of the lead screw part 75. The bottom of the sliding block 76 is fixedly connected with a mounting cover 77. A sliding sleeve 79 is fixedly connected to the side of the mounting cover 77 close to the side plate 2.

[0032] The sliding sleeve 79 is slidably connected with the guide rod 78. The bottom of the mounting cover 77 is fixedly installed with a collection box 710 through bolts. One end of a torsion spring 713 is fixedly connected with the inner wall of the mounting cover 77, and the other end of the torsion spring 713 is fixedly connected with a fitting rod 712. Two top sleeve bodies 714 are symmetrically and fixedly installed on the inner top surface of the mounting cover 77. A sliding rod 716 is slidably installed inside the top sleeve body 714. The bottom ends of the two sliding rods 716 are fixedly connected with the same mounting box 717. A spring 715 is fixedly connected to the inner top surface of the top sleeve body 714.

[0033] The bottom end of the spring 715 is fixedly connected with the sliding rod 716. The sliding rod 716 is slidably connected with the top sleeve body 714. A cleaning roller 718 is rotatably installed at the bottom of the mounting box 717. The cleaning roller 718 is horizontally arranged, and the bottom end of the cleaning roller 718 is in contact with the top of the wheel body 6.

[0034] Example 1: As Figures 4 - 7 shown, the operator places the rod body 5 on the top of the positioning plate 4, starts the electric push rods 71 on both sides. The electric push rods 71 drive the contact plate 72 to move, and the contact plate 72 drives the limiting rod 73 to move. The contact rollers on the two contact plates 72 position the wheel body 6, keeping the rod body 5 and the wheel body 6 in the central position, and positioning through the positioning assembly 8. Then, the first motor 74 is started. The sliding sleeve 79 slides on the guide rod 78. The rotation of the lead screw part 75 causes the sliding block 76 and the mounting cover 77 to move horizontally, and the mounting cover 77 drives the collection box 710 to move.

[0035] Until the fitting rod 712 is in contact with the wheel body 6. At this time, the positioning assembly 8 drives the rod body 5 and the wheel body 6 to rotate. The outside of the wheel body 6 contacts the fitting rod 712. The wheel body 6 first drives the fitting rod 712 to rotate, and the fitting rod 712 drives the rotating rod 711 and the torsion spring 713 to rotate. When the elastic force of the torsion spring 713 is greater than the friction force between the fitting rod 712 and the wheel body 6, the torsion spring 713 drives the rotating rod 711 and the fitting rod 712 to reset, so that the fitting rod 712 can assist in rotating and scraping.

[0036] The elastic force of the first spring 715 drives the slide bar 716 and the mounting box 717 to press downwards. The mounting box 717 drives the cleaning roller 718 to press tightly against the outer ring of the wheel body 6. As the wheel body 6 rotates, the cleaning roller 718 facilitates the cleaning of the outer ring of the wheel body 6, and the sundries cleaned fall into the collection box 710 for collection, solving the problem that dust and sundries will accumulate during the operation of the wheel pair, and these impurities will affect the accuracy of laser detection and the precision of subsequent dynamic balance detection.

[0037] Positioning components 8 are symmetrically arranged on both sides of the positioning plate 4.

A top bar 84 and a bottom bar 86 are sleeved and installed on the outer side of the rod body 5. Upper blocks 85 are symmetrically fixedly connected to both sides of the top bar 84. Lower blocks 87 are symmetrically fixedly connected to both sides of the bottom bar 86. Plug rods 89 are vertically slidably installed inside the upper blocks 85 and the lower blocks 87 on the same side.

[0038] Two linear guide rails 9 are fixedly installed in parallel on the upper parts of the inner sides of the two side plates 2. The output ends of the linear guide rails 9 are fixedly installed with mounting sleeves 10. The laser detector 11 is fixedly installed at the bottom of the mounting sleeve 10. Side rods 88 are fixedly connected in an array on the outsides of the top bar 84 and the bottom bar 86. The rotating rods 83 and the side rods 88 are arranged at corresponding intervals. The two upper blocks 85 are respectively located on one side of the front and the back of the top bar 84. The two lower blocks 87 are respectively located on one side of the front and the back of the bottom bar 86.

[0039] Two guide plates 810 are symmetrically fixedly connected to the top of the top bar 84. Step grooves 811 are symmetrically formed on the top surface of the top bar 84. Communication grooves 812 are symmetrically formed on the bottom surface of the top bar 84. The communication grooves 812 are communicated with the step grooves 811. An upper rod 813 is slidably connected inside the step grooves 811.

[0040] The bottom end of the upper rod 813 is fixedly connected with a piston 814. The piston 814 is slidably connected with the step grooves 811. A second spring 815 is sleeved on the outer side of the upper rod 813. The top end of the upper rod 813 is fixedly connected with a top block 816. The two ends of the second spring 815 are respectively fixedly connected with the piston 814 and the inner top surface of the step grooves 811. The top block 816 is located outside the top bar 84. A pull bar 817 is fixedly connected to the top end of the top block 816.

[0041] The stay bar 817 is guided by the guide plate 810 and fixedly connected to the top end of the insertion rod 89. The bottom end of the bottom bar 86 is fixedly connected with a bottom block 818. A central block 819 is fixedly connected to the middle of the inside of the bottom block 818. Two springs three 820 are symmetrically and fixedly connected to both ends of the central block 819. One end of the spring three 820 away from the central block 819 is fixedly connected with a bolt 821. The bolt 821 is slidably connected to the bottom block 818. A plurality of slots 822 are evenly formed in the lower part of the side of the insertion rod 89 close to the top bar 84.

[0042] Embodiment 2: As Figures 8 - 13 shown, after the rod body 5 and the wheel body 6 are placed in the middle position, by sleeving the top bar 84 and the bottom bar 86 on the upper part and the lower part of the rod body 5 respectively, the communication groove 812 fits with the rod body 5, and the inside of the step groove 811 and the communication groove 812 is in a sealed state. The side rod 88 and the rotating rod 83 are kept at an interval. When the rotating rod 83 rotates, it can drive the side rod 88 to rotate. The insertion rod 89 passes through the upper block 85 and is inserted into the lower block 87. The insertion rod 89 pulls the stay bar 817. The stay bar 817 is guided by the guide plate 810 and will drive the top block 816 to rise. The top block 816 drives the upper rod 813 and the piston 814 to rise.

[0043] The piston 814 compresses the spring two 815 and evacuates the inside of the step groove 811. The step groove 811 and the communication groove 812 are in a negative pressure state, making the positioning of the top bar 84 and the bottom bar 86 on the rod body 5 more stable. And the insertion rod 89 descends. When the slot 822 contacts the bolt 821, the elastic force of the spring three 820 drives the bolt 821 to pop out, and the bolt 821 is stuck in the slot 822, which is convenient for positioning the insertion rod 89 and facilitating the subsequent rotation of the rod body 5 and the wheel body 6.

[0044] By starting the motor two 81, the motor two 81 drives the rotating cylinder 82 and the rotating rod 83 to rotate. The rotating rod 83 drives the side rod 88 to rotate. The side rod 88 keeps the stable rotation of the rod body 5 and the wheel body 6 through the top bar 84 and the bottom bar 86, which is convenient for cleaning the wheel body 6. Move the mounting cover 77 away and start the linear guide rail 9. The linear guide rail 9 drives the mounting sleeve 10 and the laser detector 11 to move and detect, solving the problem that when the wheel pair is driven to rotate by the turntable, slippage may occur between the turntable and the wheel pair, thereby reducing the stability of the rotation of the wheel pair.

[0045] Working principle: When using this device, first, as Figures 1 - 13As shown, the operator places the rod body 5 on the top of the positioning plate 4. The contact rollers on the two side contact plates 72 position the wheel body 6, keeping the rod body 5 and the wheel body 6 in the central position. The top strip 84 and the bottom strip 86 are respectively sleeved on the upper and lower parts of the rod body 5. The step groove 811 and the communication groove 812 are in a negative pressure state, making the positioning of the top strip 84 and the bottom strip 86 on the rod body 5 more stable. The plug pin 821 is inserted into the slot 822 to facilitate the positioning of the insertion rod 89. The first motor 74 is started, and the sliding sleeve 79 slides on the guide rod 78. The screw rod part 75 rotates to make the sliding block 76 and the mounting cover 77 move horizontally. The mounting cover 77 drives the collection box 710 to move until the fitting rod 712 fits with the wheel body 6. By starting the second motor 81, the second motor 81 drives the rotating cylinder 82 and the rotating rod 83 to rotate, keeping the stable rotation of the rod body 5 and the wheel body 6, facilitating the cleaning of the wheel body 6. The fitting rod 712 can assist in rotating and scraping, and the cleaning roller 718 is convenient for cleaning the outer ring of the wheel body 6. The sundries to be cleaned fall into the collection box 710 for collection. After the cleaning is completed, the mounting cover 77 is moved away, and the linear guide 9 is started. The linear guide 9 drives the mounting sleeve 10 and the laser detector 11 to move for detection.
