Description

Technical Field

[0001] This utility model relates to the field of support roller installation technology, and in particular to an automatic support roller pinning machine. Background Technology

[0002] Track rollers are a core component of the walking system of tracked construction machinery (such as excavators, bulldozers, and tracked cranes). They directly support the weight of the machine and roll on the track rails, enabling the machine to move smoothly.

[0003] Track rollers consist of components such as the roller body and end caps. During installation, the end caps need to be inserted into the axle and then secured with pins to complete the assembly of the end cap and the roller body. The current method of pinning involves manually aligning the end cap (ensuring the pin holes on the end cap correspond to the pin holes on the axle), then using one hand to hold the pin in place while the other hand uses a hammer to tap the pin. Throughout this process, problems such as misalignment of the hammer and pin holes can easily occur. Utility Model Content

[0004] This utility model provides an automatic pinning machine for support rollers, which solves the technical problem that the pin holes are difficult to align and are prone to deviation when assembling the roller body and end cap.

[0005] To achieve this technical objective, the present invention adopts the following solution: an automatic support roller knocking machine, comprising a worktable, a support mechanism, a positioning mechanism, and a knocking mechanism; The support mechanism is set on the workbench to support and fix the wheel body; The positioning mechanism is located at one end of the support mechanism and is used to position the end cover and the axle so that the pin hole of the end cover and the pin hole of the axle are coaxial. The pin-driving mechanism is located at one end of the support mechanism and is used to drive the pin shaft into the pin hole.

[0006] Furthermore, the support mechanism includes a support frame, a motor, a lead screw, a slider, and an arc-shaped clamping plate; The support frame is fixed on the top surface of the workbench. The top surface of the support frame is provided with a downwardly curved receiving groove for accommodating the wheel body, and the top surface of the support frame is provided with a clearance groove perpendicular to the receiving groove. The motor is fixed to the side of the worktable; The lead screw is coaxially and fixedly connected to the output shaft of the motor, and rotatably connected to the support frame.

The arc-shaped clamp is bent towards the wheel body.

[0007] Furthermore, the positioning mechanism includes a vertical plate, a positioning rod, and a spring; The upright plate is fixed to the top surface of the workbench; The positioning rod is slidably inserted into the upright plate. One end of the positioning rod is fixed with a limiting ring, which abuts against the upright plate. A limiting disc is fixed on the rod body of the positioning rod.

[0013] To fully understand the purpose, features and effects of this utility model, the following specific embodiments will be used to describe this utility model in detail, but this utility model is not limited thereto.

[0014] like Figures 1-2 As shown, this utility model discloses an automatic support roller knocking machine, including a worktable 1, a support mechanism 2, a positioning mechanism 3 and a knocking mechanism 4; Support mechanism 2 is installed on workbench 1 to support and fix wheel body 5; The positioning mechanism 3 is located at one end of the support mechanism 2 and is used to position the end cover 6 and the wheel axle 7 so that the pin hole of the end cover 6 and the pin hole of the wheel axle 7 are coaxial. The pin-driving mechanism 4 is located at one end of the support mechanism 2 and is used to drive the pin 8 into the pin hole.

[0015] Furthermore, the support mechanism 2 includes a support frame 21, a motor 22, a lead screw 23, a slider 24, and an arc-shaped clamping plate 25; The support frame 21 is fixed on the top surface of the workbench 1. The top surface of the support frame 21 is provided with a downwardly curved receiving groove 211 for accommodating the wheel body 5. The top surface of the support frame 21 is provided with a clearance groove 212 perpendicular to the receiving groove 211. The motor 22 is fixed to the side of the workbench 1; The lead screw 23 is coaxially and fixedly connected to the output shaft of the motor 22, and the lead screw 23 is rotatably connected to the support frame 21. The two ends of the lead screw 23 are respectively provided with a forward thread and a reverse thread. The two sliders 24 are symmetrically arranged, and the two sliders 24 are respectively threaded onto the outside of the positive thread and the negative thread; The arc-shaped clamp 25 is movably disposed in the clearance groove 212. The arc-shaped clamp 25 is fixed to the top of the side of the slider 24 and bends towards the wheel body 5.

[0016] Furthermore, the positioning mechanism 3 includes a vertical plate 31, a positioning rod 32, and a spring 33; The upright plate 31 is fixed on the top surface of the workbench 1; The positioning rod 32 is slidably inserted into the upright plate 31. One end of the positioning rod 32 is fixed with a limiting ring 34, which abuts against the upright plate 31. A limiting disc 35 is fixed on the rod body of the positioning rod 32. Spring 33 is sleeved on the outside of positioning rod 32, and the two ends of spring 33 abut against vertical plate 31 and limiting plate 35 respectively.

[0017] Furthermore, the knocking mechanism 4 includes a vertical plate 43, an electric actuator 41, and a mounting plate 42; The vertical plate 43 is fixed to the top of the workbench 1, and the vertical plate 43 is arranged opposite to the upright plate 31; The electric actuator 41 is horizontally fixed on the vertical plate 43. The movable end of the electric actuator 41 can slide through the vertical plate 43. The movable end of the electric actuator 41 is coaxially arranged with the positioning rod 32. The limiting plate 35 is coaxially fixed on the moving end of the electric actuator 41, and the limiting plate 35 is fitted with a pin 8.

[0018] by Figure 2 For example, in use, first pull the limiting ring 34 to move the positioning rod 32 to the left. Then place the wheel body 5 in the receiving groove 211, adjust the position of the wheel body 5 and the wheel axle 7 so that the positioning rod 32 is aligned with the pin hole on the wheel axle 7, and release the limiting ring 34 to insert the positioning rod 32 into the pin hole. Start the motor 22, which drives the lead screw 23 to rotate, causing the two sliders 24 to move closer to each other until the arc-shaped clamping plate 25 clamps the wheel body 5. Pull the limiting ring 34 again to pull the positioning rod 32 out of the pin hole. Install the end cover 6 onto the wheel axle 7, and then release the limiting ring 34. The positioning rod 32, driven by the spring 33, presses against the end cover 6. Rotate the end cover 6 to insert the positioning rod 32 into the pin hole of the end cover 6. Then rotate the wheel axle 7 to insert the positioning rod 32 into the pin hole of the wheel axle 7. Insert the pin 8 onto the mounting plate 42 and activate the electric push rod 41. The electric push rod 41 will drive the pin 8 into the pin hole. As the pin 8 is inserted, the positioning rod 32 gradually moves away from the pin hole.

[0019] Furthermore, to facilitate the insertion of the positioning rod 32 into the pin hole, the outer diameter of the positioning rod 32 is smaller than the inner diameter of the pin hole. To ensure better alignment of the positioning rod 32 with the pin holes on the end cover 6 and the axle 7, an arc-shaped strip 321 is fixed to the top surface of the outer wall of the positioning rod 32, abutting against the inner wall of the pin hole. In this case, a flat key and a keyway can be used to connect the upright plate 31 and the positioning rod 32, thereby preventing the positioning rod 32 from rotating and further ensuring that the arc-shaped strip 321 always abuts against the top of the pin hole, guaranteeing the alignment effect. Flat keys and keyways are common existing technologies and will not be described in detail here.

[0020] Finally, it should be noted that the above-listed embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art can make modifications and variations to the present invention. If such modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should be considered as being within the protection scope of the present invention.
