Abstract
Description
Technical Field
[0001] This utility model relates to the field of traction wheel processing technology, specifically a fixing mechanism for processing high-power, thick-end-face traction wheels. Background Technology
[0002] The traction sheave is the rope sheave on the traction machine, and it is the device that transmits traction power in the elevator. It uses the friction between the traction steel wire rope and the rope groove on the edge of the traction sheave to transmit power. Since the traction sheave has to bear all the dynamic and static loads of the car and the load capacity, it is required to have high strength, good toughness, wear resistance, and impact resistance. The traction sheave production process requires grooving and grinding, and it needs to be fixed. However, after fixing the traction sheave, its stability still needs to be improved, and fixing different types and sizes of traction sheaves is quite troublesome.
[0003] For example, the patent with authorization announcement number CN218575608U describes a traction wheel processing clamping fixture with a self-locking fixing structure. It achieves height adjustment of the clamping component through the cooperation of the lead screw and the connecting plate, and achieves clamping of the traction wheel through the cooperation of the bidirectional threaded rod and the connecting plate. However, after clamping, it does not support the bottom of the traction wheel, but only relies on the clamping force on both sides to lift the traction wheel, which leads to a great hidden danger in the stability of its clamping. Moreover, when clamping traction wheels of different sizes, its side positioning plate may affect the normal clamping operation, making it impossible to achieve self-centering clamping of the traction wheel, thus reducing the practicality of the device.
[0004] Based on this, a fixing mechanism for machining high-power, thick-end-face traction wheels is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content
[0005] The purpose of this utility model is to provide a fixing mechanism for machining high-power, thick-end-face traction wheels, so as to solve the problems in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A fixing mechanism for machining a high-power, thick-faced traction wheel includes a base and a worktable. Support rods are uniformly fixedly connected to the outer wall of the base. A triangular reinforcing plate is fixedly connected to the bottom end of each support rod, and the outer wall of the triangular reinforcing plate is fixedly connected to the outer wall of the base. A guide slider is fixedly connected to the top end of each support rod, and the guide slider is slidably connected to a guide groove at the bottom end of the worktable. The traction wheel body is mounted on the top end of the worktable. A support plate is fixedly connected to the side wall of the base. A positioning component is installed inside the base. A fixing component is installed on the worktable, and a rotating component is installed on the support plate.
[0008] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

When the worktable rotates, the guide slider at the top of the support rod cooperates with the guide groove at the bottom of the worktable to guide it, making the rotation of the worktable smooth. The worktable drives the traction wheel body to rotate synchronously, thereby changing the processing position. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0025] In one embodiment, such as Figures 1-4 As shown, a fixing mechanism for processing a high-power, thick-end-face traction wheel includes a base 1 and a worktable 14. Support rods 11 are uniformly fixedly connected to the outer wall of the base 1. A triangular reinforcing plate 12 is fixedly connected to the bottom end of the support rods 11. The outer wall of the triangular reinforcing plate 12 is fixedly connected to the outer wall of the base 1. A guide slider 13 is fixedly connected to the top end of the support rods 11. The guide slider 13 is slidably connected to a guide groove opened at the bottom end of the worktable 14. A traction wheel body 15 is provided at the top end of the worktable 14. A support plate 16 is fixedly connected to the side wall of the base 1. A positioning component 2 is provided inside the base 1. A fixing component 3 is provided on the worktable 14. A rotating component 4 is provided on the support plate 16.
[0026] In this embodiment, the traction wheel body 15 is initially positioned by the positioning component 2, so that the traction wheel body 15 is located in the middle of the worktable 14, which facilitates subsequent processing. Then, the traction wheel body 15 is fixed by the fixing component 3 to prevent the traction wheel body 15 from shifting during subsequent processing. During the processing, the traction wheel body 15 can be rotated by the rotating component 4 as needed to facilitate processing.
[0027] In an optional embodiment, such as Figure 3 As shown, the positioning component 2 includes a fixed frame 21. The outer wall of the fixed frame 21 is fixedly connected to the interior of the worktable 14. A first motor 22 is fixedly connected to the top of the fixed frame 21. A first lead screw 23 is fixedly connected to the output end of the first motor 22. The outer wall of the first lead screw 23 is rotatably connected to the interior of the fixed frame 21. A sleeve 24 is threadedly connected to the outer wall of the first lead screw 23. Four movable rods 25 are evenly rotatably connected to the outer wall of the sleeve 24. A top rod 26 is rotatably connected to the top of the movable rods 25. The top rod 26 is slidably connected to a groove opened on the fixed frame 21. The end of the top rod 26 contacts the inner wall of the traction wheel body 15. When the first motor 22 is started, the first lead screw 23 is driven to rotate. The first lead screw 23 drives the sleeve 24 to move along its axial direction. The sleeve 24 drives the movable rods 25 to move, so that the movable rods 25 push the top rod 26, so that the limiting block 27 slides in the groove opened on the top rod 26, and so that the top rod 26 abuts against the inner wall of the traction wheel body 15.
[0028] In an optional embodiment, such as Figure 3 As shown, the opening on the fixed frame 21 is symmetrically fixedly connected to the limiting block 27. The limiting block 27 is slidably connected to the groove on the top rod 26. The limiting block 27 limits and guides the top rod 26 so that the top rod 26 can only move laterally and will not deviate.
[0029] In an optional embodiment, such as Figure 3 As shown, each end of the push rod 26 that contacts the traction wheel body 15 is equipped with a pressure sensor, and the pressure sensor is electrically connected to the first motor 22 through a PLC controller. The pressure sensor detects the pressure of each push rod 26 pressing the traction wheel body 15 in real time. When the PLC controller determines that the pressure value detected by the pressure sensor at the end of each push rod 26 reaches the set threshold and the difference between them is within the allowable range (or nearly equal), it controls the first motor 22 to stop working.
[0030] In an optional embodiment, such as Figure 4As shown, the fixing assembly 3 includes a second motor 31, the outer wall of which is fixedly connected to the outer wall of the worktable 14. A second lead screw 32 is fixedly connected to the output end of the second motor 31, and the second lead screw 32 is rotatably connected to the interior of the worktable 14. A slider 33 is threadedly connected to the outer wall of the second lead screw 32, and the slider 33 is slidably connected to a groove on the worktable 14. A mounting plate 34 is fixedly connected to the top of the slider 33, and a clamping plate 35 is fixedly connected to the outer wall of the mounting plate 34. The side wall contacts the outer wall of the traction wheel body 15. The working surface of the clamping plate 35 is evenly distributed with anti-slip ridges. The second motor 31 is started, and the second lead screw 32 is driven to rotate, so that the slider 33 moves axially along the second lead screw 32, which drives the mounting plate 34 and the clamping plate 35 to move radially along the traction wheel body 15, so that the working surface of the clamping plate 35 is in tight contact with the outer peripheral wall of the traction wheel body 15. The anti-slip ridges on the working surface of the clamping plate 35 increase the friction, making the clamping and fixing more stable.
[0031] In an optional embodiment, such as Figure 4 As shown, the rotating assembly 4 includes a third motor 41. The bottom end of the third motor 41 is fixedly connected to the top end of the support plate 16. A gear 42 is fixedly connected to the output end of the third motor 41. A gear ring 43 meshes with the outer wall of the gear 42. The top end of the gear ring 43 is fixedly connected to the bottom end of the worktable 14. The third motor 41 drives the gear 42, which in turn drives the gear ring 43 to rotate. The gear ring 43 drives the worktable 14 to rotate synchronously, thereby changing the processing position of the traction wheel body 15 and making the processing more convenient.
[0032] The above embodiment discloses a fixing mechanism for machining a high-power, thick-end-face traction wheel. When fixing the traction wheel body 15, the traction wheel body 15 is placed on the worktable 14, and the fixing frame 21 is positioned in the middle of the traction wheel body 15. Then, the first motor 22 is started, driving the first lead screw 23 to rotate. The first lead screw 23 drives the sleeve 24 to move axially, and the sleeve 24 drives the movable rod 25 to move, causing the movable rod 25 to push the top rod 26, so that the limiting block 27 is positioned on the top rod 26. The push rods 26 slide within the grooves, causing them to abut against the inner wall of the traction sheave body 15. When all four push rods 26 are in contact with the inner wall of the traction sheave body 15, and the pressures borne by the pressure sensors integrated at the ends of the push rods 26 are nearly equal, the traction sheave body 15 is located in the center of the worktable 14. The pressure sensors then feed back information to the PLC controller, causing the first motor 22 to stop working, thus completing the positioning of the traction sheave body 15. Afterward, the second motor 31 can be started. The machine 31 drives the second lead screw 32 to rotate, causing the slider 33 to move axially along the second lead screw 32. This causes the mounting plate 34 and the clamping plate 35 to move radially along the traction wheel body 15, making the working surface of the clamping plate 35 come into close contact with the outer peripheral wall of the traction wheel body 15, thereby fixing the traction wheel body 15. Then, the traction wheel body 15 can be processed. During the processing, the third motor 41 can drive the gear 42, which drives the gear ring 43 to rotate. The gear ring 43 drives the worktable 14 to rotate synchronously, thereby changing the processing position of the traction wheel body 15 and making the processing more convenient. In summary, the positioning component 2 initially positions the traction wheel body 15, placing it in the middle of the worktable 14 for convenient subsequent processing. Then, the fixing component 3 fixes the traction wheel body 15 to prevent displacement during subsequent processing. During the processing, the rotating component 4 can be used to rotate the traction wheel body 15 as needed to facilitate processing.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
