[0001] The utility model relates to the technical field of shaft production, in particular to a polishing machine for shaft surface treatment. Background Technique
[0002] A shaft is a cylindrical object that passes through the middle of a bearing, a wheel, or a gear. A shaft is a mechanical part that supports a rotating part and rotates with it to transmit motion, torque, or bending moment; generally it is a metal round rod, and each section can have a different diameter.
[0003] During the production of a shaft, in order to improve the insertion of the shaft into workpieces such as bearings, deburring treatment needs to be carried out on the shaft surface. Therefore, a polishing machine is required. A polishing machine is a machine that polishes the surface of a workpiece and removes burrs. When the existing polishing machine is in use, the polishing wheel needs to make pressure contact with the surface of the shaft. If a full-wrap support is adopted at the bottom of the shaft, it is very easy for waste chips to fall on the support surface and affect the subsequent surface polishing of the shaft. If multiple spaced-apart support frames are used to support the shaft, it will be affected by the length of the shaft itself, reducing the adaptability of the polishing machine.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0025] Refer to Figures 1 - 4, A polishing machine for shaft surface treatment, including an operating table 1, with support legs installed at the bottom of the operating table 1. A polishing device is arranged above the operating table 1. Among them, the polishing device includes a polishing wheel 24, a driving shaft 25 is coaxially arranged on the polishing wheel 24, and the end of the driving shaft 25 is rotatably installed in a U-shaped seat 26 with an opening downward. One end of the driving shaft 25 is connected to a third driving motor 27, and the third driving motor 27 is fixed on the U-shaped seat 26. The third driving motor 27 provides power for the rotation of the polishing wheel 24. A lifting mechanism 28 is vertically installed on the top of the U-shaped seat 26. The lifting mechanism 28 is fixed on the slider of a linear motor 31 through a fixing frame 29, and the slide rail of the linear motor 31 is arranged along the length direction of the strip-shaped groove 2 and is connected to the operating table 1 through an L-shaped frame 33. When the polishing wheel 24 polishes the shaft, the linear motor 31 can drive the polishing wheel 24 to move, that is, drive the polishing wheel 24 to move along the length direction of the shaft, so as to polish the shaft sufficiently.
[0026] When the lifting mechanism 28 controls the lifting of the U-shaped seat 26, at least one third guiding shaft 30 is arranged in parallel on the side of the lifting mechanism 28. The bottom of the third guiding shaft 30 is fixed on the U-shaped seat 26, and the top of the third guiding shaft 30 slidably penetrates through the fixing frame 29 to provide guidance for the lifting of the polishing wheel 24 and make the lifting of the polishing wheel 24 more stable.
[0027] As Figure 1 and Figure 3 shown, strip-shaped grooves 2 are correspondingly opened at both ends of the operating table 1. A lead screw 3 is arranged in the strip-shaped groove 2. One end of the lead screw 3 is rotatably installed at the end of the strip-shaped groove 2, and the other end of the lead screw 3 is rotatably installed on a fixed seat 9, and the fixed seat 9 is fixed in the strip-shaped groove 2. And a driving device is connected to the end of the lead screw 3 close to the fixed seat 9; A moving seat 11 is threadedly connected to each lead screw 3 through a nut. A support seat 12 is installed on the top of the moving seat 11. Support wheels 13 are arranged above both ends of the support seat 12. The two support wheels 13 are arranged adjacent to each other, and a support plate 14 is rotatably installed at the end of the support wheel 13. The bottom of the support plate 14 is fixed on the support seat 12. During polishing, the shaft can be placed between two adjacent support wheels 13. In the actual use process, the gap between the polishing wheel 24 and two adjacent support wheels 13 corresponds. When the lead screw 3 rotates, the support wheels 13 can be controlled to move along the length direction of the strip-shaped groove 2, that is, when placing the shaft, the support wheels 13 can be rotated by the lead screw 3 to move along with the movement of the polishing wheel 24, so that there is always a pair of support wheels 13 under the polishing wheel 24 to support the shaft and provide better support for the shaft; And the movement of the support wheels 13.
[0028] Among them, the driving device includes a first driving motor 7, the first driving motor 7 is arranged in the first chassis 8, and the first chassis 8 is fixed on the bottom of the operating table 1. A second pulley 5 is connected to the end of the first driving motor 7. Above the second pulley 5, there is a first pulley 4. The first pulley 4 is coaxially fixed to one end of the lead screw 3 close to the fixed seat 9, and the first pulley 4 and the second pulley 5 are connected by a belt 6 to provide power for the rotation of the lead screw 3.
[0029] Furthermore, at least one first guiding shaft 32 parallel to the lead screw 3 is arranged in the strip-shaped groove 2. The end parts of the first guiding shaft 32 are respectively fixed to the fixed seat 9 and the end of the strip-shaped groove 2, and the first guiding shaft 32 slidably penetrates through the moving seat 11 to guide the movement of the moving seat 11, improving the movement stability of the moving seat 11.
[0030] In order to prevent sundries such as waste chips and dust from falling on the pulleys and affecting the transmission of the belt 6, a protective cover 10 is arranged on the relatively far sides of the two fixed seats 9. The protective cover 10 is fixed to the fixed seat 9. Among them, the first pulley 4, the second pulley 5, and the belt 6 are all placed inside the protective cover 10 to wrap and protect the pulleys and prevent sundries from falling on them.
[0031] It should be noted that the strip-shaped groove 2 penetrates through the operating table 1. During actual use, a cross-flow fan can be installed on the L-shaped frame 33 facing the strip-shaped groove 2 to blow air into the strip-shaped groove 2, thereby preventing sundries such as waste chips and dust from falling on the lead screw 3 and affecting the transmission of the lead screw 3 to the moving seat 11.
[0032] As Figure 1 and Figure 3 shown, clamping blocks 15 are arranged above both ends of the operating table 1. The two clamping blocks 15 are arranged opposite to each other, and the cross-section of the clamping block 15 is trapezoidal. One end with a larger surface area of one clamping block 15 is rotatably installed on the strip-shaped plate 16, and a pushing device 17 is vertically installed on the other side of the strip-shaped plate 16. The pushing device 17 is fixed to the first support frame 18 through a bracket 19, and the first support frame 18 is fixed to the operating table 1; while a second driving motor 21 is connected to one end with a larger surface area of the other clamping block 15. The second driving motor 21 is arranged in the second chassis 22, and the second chassis 22 is installed on the second support frame 23, and the second support frame 23 is fixed to the operating table 1. After placing the shaft on the support wheel 13, first lean one end of the shaft against the clamping block 15 on the second driving motor 21, and then control the pushing device 17 to push the clamping block 15 against the other end of the shaft to clamp and fix the shaft.
[0033] Further, a second guide shaft 20 is provided in parallel to the side of the pushing device 17. One end of the second guide shaft 20 is fixed to the strip-shaped plate 16, and the other end of the second guide shaft 20 slidably penetrates through the bracket 19, providing a guiding function for the pushing of the clamping block 15 by the pushing device 17, so that the clamping block 15 is always aligned with another clamping block 15 during movement.
[0034] During use, first adjust the position of the support wheels 13 and the distance between the support wheels 13 according to the length of the shaft. Then, after placing the shaft on the support wheels 13 and fixing it with the clamping blocks 15, the polishing wheel 24 can be lowered to polish the shaft. When the linear motor 31 controls the movement of the polishing wheel 24 to polish the surface of the shaft, the second drive motor 21 will also start to operate, enabling the shaft to rotate during the polishing process, so as to change the polished surface of the shaft and allow the polishing wheel 24 to fully polish the shaft. When the polishing wheel 24 moves with the linear motor 31, when the polishing wheel 24 moves above one of the strip-shaped grooves 2, the support wheel 13 in this strip-shaped groove 2 will also move with the movement of the polishing wheel 24 and always maintain the relative state between the support wheel 13 and the polishing wheel 24. When the polishing wheel 24 moves into another strip-shaped groove 2, the support wheel 13 in this strip-shaped groove 2 will also move correspondingly with the polishing wheel 24, while the support wheel 13 in the previous strip-shaped groove 2 stops operating. In this way, when providing support at the bottom of the shaft, a reaction force can also be provided to the pressure exerted by the polishing wheel 24 on the shaft, ensuring that the shaft will not be deformed or damaged below the polishing wheel 24.
[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered within the protection scope of the present invention.
