DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] Embodiment 1, as Figure 1 and Figure 2As shown, a positioning and punching device for supporting wheel processing includes a shell 1, a base 2 is fixedly connected to the lower end of the shell 1, a control box 3 is fixedly installed at the front end of the shell 1, a support frame 4 is fixedly connected to the middle of the upper end of the shell 1, a punching mechanism 5 is fixedly installed on the inner surface of the support frame 4 symmetrically, a positioning component 6 is commonly provided at the inner cavity and the upper end of the shell 1, and a cleaning component 7 is commonly provided at the side of the support frame 4 close to each other and the rear end of the shell 1.

[0034] During the implementation of this embodiment, the supporting roller is placed in the positioning component 6, and then the control box 3 is operated to support the supporting roller through the positioning component 6, and corresponding adjustments are made according to the actual thickness of the supporting roller to keep the supporting roller in a horizontal state. Then, the supporting roller is clamped and fixed to locate the center position of the supporting roller. Before punching the supporting roller, the outer surface of the hole at the upper end of the supporting roller is cleaned by the cleaning component 7. By operating the control box 3, the punching mechanism 5 performs relevant punching operations on the supporting roller.

[0036] The punching mechanism 5 mentioned above is a mature punching technical means and equipment in the prior art. In this solution, its function of punching holes in the supporting wheels is utilized, and its internal structure, principle and connection method are not further explained.

[0037] Specifically, in order to achieve the positioning and support of the supporting wheels, refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 In this embodiment, the positioning assembly 6 includes two symmetrical slide grooves 61 opened at the upper end of the shell 1, and the inner surfaces of the two slide grooves 61 are jointly provided with a propulsion mechanism 62, and the upper end of the propulsion mechanism 62 is provided with a clamping mechanism 63, and the inner surface of the propulsion mechanism 62 is provided with a lifting mechanism 64, and the inner surface of the lifting mechanism 64 is provided with a grinding and collecting mechanism 65, and the inner surfaces of the two slide grooves 61 are symmetrically provided with a protective mechanism 66.

[0038] For further information, see Figure 4 and Figure 6In this embodiment, the clamping mechanism 63 includes a fixed plate 631 which is symmetrically fixed to the upper end of the working plate 623, an oil tank 632 is fixedly connected to the lower part of the inner surface of the shell 1, and cylinders 633 are fixedly connected to the inner surfaces of the two fixed plates 631. The upper part of the inner surface of the oil tank 632 penetrates and extends to the inner surfaces of the two cylinders 633 and is fixedly connected to a connecting pipe 634, and the lower end of the connecting pipe 634 is fixedly connected to an oil pump 635. The inner surfaces of the two cylinders 633 are slidably connected to piston rods 636, and the outer surfaces of the two piston rods 636 are sleeved with springs 637. The two ends of the two springs 637 are respectively fixedly connected to the pistons on the piston rods 636 and the inner surface of the cylinders 633, and the ends of the two piston rods 636 that are close to each other are fixedly connected to clamping blocks 638.

[0039] For further information, see Figure 4 and Figure 7 In this embodiment, the lifting mechanism 64 includes two concave frames 641 fixedly connected to the inner surface of the working plate 623, the two concave frames 641 are slidably connected to the outer shell 1, the inner surfaces of the two concave frames 641 are fixedly connected with fixed blocks 643, the inner surfaces of the two fixed blocks 643 are slidably connected with piston rods 642, the outer surfaces of the two piston rods 642 are sleeved with springs 644, the two ends of the two springs 644 are respectively fixedly connected to the piston on the piston rod 642 and the lower end of the fixed block 643, the upper ends of the two piston rods 642 are fixedly connected with concave frames 645 slidably connected to the inner surface of the concave frame 641, the lower parts of the inner surfaces of the two concave frames 641 penetrate and extend to the inner surface of the connecting pipe 634, and are fixedly connected with connecting pipes 646, and the intersection of the outer surfaces of the connecting pipe 634 and the outer surfaces of the connecting pipe 646 is fixedly installed with a solenoid valve 647.

[0040] During the implementation process, the supporting rollers are placed on the upper ends of the two concave frames 645, and then the oil pump 635 is started to draw the hydraulic oil in the oil tank 632 into the connecting pipe 634. Then, under the action of the solenoid valve 647, the hydraulic oil enters the inner cavity of the two concave frames 641 through the connecting pipe 646, and pushes the two piston rods 642 to move upward, so that the spring 644 is in a compressed state, and at the same time pushes the concave frame 645 to slide upward on the inner surface of the concave frame 641, thereby driving the supporting rollers to adjust their positions, so that the positions of the holes punched in the supporting rollers can be on the same horizontal plane, and have the ability to adjust the height of supporting rollers of different thicknesses, which can ensure the accuracy of the punching position, avoid error accumulation, improve the processing quality, enhance the versatility and flexibility of the device, and enable supporting rollers of different specifications to be properly supported and positioned, thereby optimizing the production process and improving the overall work efficiency and processing accuracy.

[0041] Secondly, after the supporting operation is completed, the connecting pipe 2 646 is closed through the cooperation of the solenoid valve 647 and the oil pump 635, and the hydraulic oil enters the two cylinders 633 through the connecting pipe 1 634, and then the two piston rods 1 636 are pushed to move closer to the middle, so that the two clamping blocks 638 gradually clamp the supporting wheels, limit the front, back, left and right positions of the supporting wheels, so that the supporting wheels can be accurately positioned to avoid position deviations that lead to inaccurate punching positions, thereby further improving the efficiency and accuracy of punching.

[0042] The solenoid valve 647 mentioned above is a mature control technology means and equipment in the prior art. In this solution, it is used to control the flow direction of the liquid and close or open the connecting pipe 1 634 and the connecting pipe 2 646. Its internal structure, principle and connection method will not be explained again.

[0043] The oil pump 635 mentioned above is a mature oil pumping technology means and equipment in the prior art. In this solution, its function of collecting hydraulic oil is utilized, and its internal structure, principle and connection method are not further explained.

[0044] The connecting pipe 1 634 and the connecting pipe 2 646 are both made of soft materials.

[0045] For further information, see Figure 4 , Figure 7 and Figure 8 In this embodiment, the grinding and collecting mechanism 65 includes an electric telescopic rod 651 fixedly connected to the lower part of the inner surface of the two concave frames 645, the upper ends of the two electric telescopic rods 651 are fixedly connected to a rectangular plate 652, the inner surfaces of the two concave frames 645 are fixedly connected to a circular hole plate 653, the inner surfaces of the two circular hole plates 653 are fixedly connected to a slider 656, the inner surfaces of the two circular hole plates 653 are provided with a spiral rod 654 slidably connected to the slider 656, the two spiral rods 654 are rotatably connected to the rectangular plate 652, the upper ends of the two spiral rods 654 are fixedly connected to a grinding block 655, the inner surfaces of the two concave frames 645 are rotatably connected to an inclined plate 657, and the inner surfaces of the two concave frames 645 are movably installed with a collection frame 658.

[0046] During the implementation process, after the drilling operation is completed, since the concave frame 645 is still supporting the supporting roller, the electric telescopic rod 651 is started at this time, so that the electric telescopic rod 651 pushes the screw rod 654 on the rectangular plate 652 to move upward. Since the screw rod 654 and the slider 656 are in a sliding connection, the screw rod 654 can move upward and rotate under the action of the slider 656, so that the two grinding blocks 655 on the screw rod 654 can enter the inner surface of the hole of the supporting roller and grind the inside of the hole, which can significantly improve the smoothness and precision of the hole, help reduce friction and wear, and improve the overall performance and life of the supporting roller. Rotational grinding can also ensure uniform grinding and avoid local excessive wear, while improving production efficiency and reducing production costs.

[0047] Secondly, during the process of drilling holes in the supporting wheels, part of the debris generated by the drilling will fall into the upper space formed by the inclined plate 657 and the concave frame 645 under the action of gravity. During subsequent grinding, the grinding block 655 moves upward to push the inclined plate 657 open, so that the inclined plate 657 rotates. During the rotation process, the debris retained in the upper space will fall into the collecting frame 658 through the rectangular hole on the concave frame 645 under the action of gravity. When it is necessary to clean the collecting frame 658, the collecting frame 658 can be taken out from the inner surface of the concave frame 645. This can avoid the debris residue affecting the grinding quality and hole accuracy, and prevent the debris from damaging the device and operators. The timely collection of debris can also keep the working environment clean, improve production efficiency, and reduce cleaning costs.

[0048] For further information, see Figure 4 and Figure 5 In this embodiment, the propulsion mechanism 62 includes a threaded rod 621 that passes through the front end of the shell 1 and extends to the rear end for rotational connection. The rear end of the threaded rod 621 is fixedly connected to a dual-axis motor 624 that is fixedly connected to the rear end of the shell 1. The outer surface of the threaded rod 621 is threadedly connected to a T-shaped block 622 that is slidably connected to the inner surface of the slide groove 61. The upper end of the T-shaped block 622 is fixedly connected to a working plate 623. The rear end of the dual-axis motor 624 is fixedly connected to a rotating rod 625 through a coupling.

[0049] During the implementation process, after the first row of holes is punched on the supporting wheels, the second row of holes needs to be punched. At this time, the front output end of the dual-axis motor 624 is started to drive the threaded rod 621 to rotate through the coupling. Under the action of the threaded connection, the T-shaped block 622 slides on the inner surface of the slide groove 61, and then the working plate 623 can be driven to move, so that the position of the supporting wheels is changed to meet the actual punching needs. There is no need to perform secondary positioning and fixing operations again, thereby improving the efficiency of punching.

[0050] For further information, see Figure 3 and Fig. 9In this embodiment, the protective mechanism 66 includes an annular groove 661 opened on the inner surface of the slide groove 61, a fixing rod 662 is fixedly connected to the inner surface of the annular groove 661, a spring 663 is fixedly connected to the outer surface of the fixing rod 662, and one end of the spring 663 is fixedly connected to a protective cloth 664 fixedly connected to one end of the T-shaped block 622.

[0051] From the above, it can be seen that the movement of the slider 656 will drive the protective cloth 664 to move, so that the spring 663 is in a deformed state, and the protective cloth 664 can always be in a taut state, which can prevent debris from entering the interior of the housing 1 during the punching operation and avoid affecting the normal operation of other components.

[0052] Embodiment 2: Based on Embodiment 1, this embodiment further includes a cleaning component 7 for cleaning the outer surface of the track roller before punching, so as to achieve the purpose of cleaning the outer surface of the track roller before punching.

[0053] Specifically, in order to clean the outer surface of the supporting wheel before drilling, refer to Figure 4 , Fig.10 and Fig.11 In this embodiment, the cleaning component 7 includes two fixing frames 71 which are symmetrically fixed to the rear portion of the upper end of the shell 1, and a fixing frame 72 is symmetrically arranged on one side of the inner surface of the support frame 4 which is close to each other. A cleaning mechanism 73 is commonly arranged on the inner surfaces of the fixing frames 1 71 and 72 on the same side, and a blower mechanism 74 is arranged at the rear end of the shell 1.

[0054] For further information, see Figure 4 and Fig.10 In this embodiment, the cleaning mechanism 73 includes a reciprocating rod 731 that is rotatably connected to the inner surfaces of the fixing frame 1 71 and the fixing frame 2 72, a limiting rod 732 is fixedly connected to the rear end of the fixing frame 2 72, a circular hole block 733 that is slidably connected to the outer surface of the reciprocating rod 731 is slidably connected to the limiting rod 732, a cleaning brush 734 is rotatably connected to the inner surface of the circular hole block 733, one end of the cleaning brush 734 and one side of the support frame 4 are fixedly connected to a transmission mechanism 735, a one-way bearing 1 736 is fixedly connected to the outer surface of the rotating rod 625, and a pulley group 1 737 is fixedly connected to the outer surface of the one-way bearing 1 736 and the outer surface of the reciprocating rod 731.

[0055] During the implementation process, after the upper end of the supporting roller is placed stably before drilling, the rear end output end of the dual-axis motor 624 is started to drive the rotating rod 625 to rotate in the positive direction through the coupling, and the two reciprocating rods 731 are driven to rotate under the cooperation of the two one-way bearings 736 and the pulley group 737. Since the reciprocating rod 731 and the circular hole block 733 are in sliding connection and under the limiting action of the limiting rod 732, the two circular hole blocks 733 reciprocate on the reciprocating rod 731 in succession. Under the cooperation of the transmission mechanism 735, the cleaning brush 734 can reciprocate to clean the debris attached to the outer surface of the upper end of the supporting roller, which can effectively remove impurities on the surface and ensure the cleanliness of the drilling position, thereby improving the accuracy and quality of the drilling, and also helping to reduce tool wear during the drilling process and improve the overall durability and reliability of the supporting roller.

[0056] The transmission mechanism 735 mentioned above is composed of a rack and a gear, and the rack and the gear are meshed with each other.

[0057] The reciprocating rod 731 and the circular hole block 733 constitute a mature ball screw mechanism in the prior art.

[0058] For further information, see Figure 4 and Fig.11 In this embodiment, the hair dryer mechanism 74 includes a circular hole frame 741 fixedly connected to the rear end of the shell 1, the inner surface of the circular hole frame 741 is rotatably connected to a transmission rod 742, the outer surface of the transmission rod 742 is fixedly connected to a fan blade 743, the outer surface of the rotating rod 625 is fixedly connected to a one-way bearing 744, the outer surface of the transmission rod 742 and the outer surface of the one-way bearing 744 are jointly fixedly connected to a pulley group 745, and the inner surface of the circular hole frame 741 is fixedly connected to an air outlet pipe 746.

[0059] During the implementation process, after cleaning or during the drilling process, the rear end output end of the dual-axis motor 624 is started to drive the rotating rod 625 to rotate in the opposite direction through the coupling. Under the transmission action of the one-way bearing 744 and the pulley group 745, the fan blades 743 on the transmission rod 742 are driven to rotate, and the air is sucked into the air outlet duct 746 through the circular hole frame 741, and the air is blown to the drilling position through the air outlet duct 746, which can effectively remove metal chips, dust and other impurities generated during drilling to prevent them from accumulating in the hole or affecting the drilling accuracy. At the same time, blowing can also help dissipate heat, reduce the temperature of the drilling area, and reduce material deformation or tool wear caused by high temperature, thereby ensuring the efficiency of the drilling process and the quality of the holes.

[0060] The pulley group 1 737 and the pulley group 2 745 mentioned above are both composed of two pulleys and a belt.

[0061] The one-way bearing 1 736 and the one-way bearing 2 744 mentioned above are both mature one-way rotating parts in the prior art. In this scheme, their function of being able to rotate in one direction and lock in the other direction is utilized, and the locking directions between the one-way bearing 1 736 and the one-way bearing 2 744 are opposite.

[0062] The dual-axis motor 624 mentioned above is a mature driving technology means and equipment in the prior art.
