Description

Technical Field

[0001] This utility model relates to the field of roller technology, specifically to a roller processing positioning and clamping device. Background Technology

[0002] "Roller" is a widely used term in many fields, especially in mechanical engineering and manufacturing. It usually refers to a cylindrical part or tool used to transmit force, support materials, or perform specific processing operations in mechanical equipment.

[0003] Roller machining positioning and clamping devices are used to stably clamp and position roller workpieces during machining. These devices are typically designed to ensure the stability and accuracy of the rollers during machining, thereby meeting specific machining requirements.

[0004] However, existing roller processing positioning and clamping devices generally use clamping force to position and clamp the roller. If the roller is used for positioning and clamping, it may cause damage and deformation. Therefore, it does not meet the existing requirements. In response, we have proposed a roller processing positioning and clamping device. Utility Model Content

[0005] The purpose of this utility model is to provide a roller processing positioning and clamping device to solve the problems mentioned in the background art. Existing roller processing positioning and clamping devices generally use clamping force to position and clamp the roller. If some rollers with weak hardness are used for positioning and clamping, it may cause damage and deformation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a roller processing positioning and clamping device, including a clamping table, wherein a second clamping cylinder is fixedly installed on both sides of the middle position inside the clamping table, the piston rod of the second clamping cylinder is connected to a metal column, and an arc-shaped rubber reinforcing head is fixedly connected to the upper end face of the metal column;

[0007] The metal column is provided with a gear rack fixed inside the clamping platform at its rear. The gear rack meshes with gears. The shaft of the gears is connected to a second gear shaft. A fourth bevel gear is fixedly sleeved on one side of the outer surface of the second gear shaft. The fourth bevel gear meshes with a third bevel gear. The shaft of the third bevel gear is connected to a first gear shaft. A second bevel gear is fixedly sleeved on one side of the outer surface of the first gear shaft. The second bevel gear meshes with the first bevel gear. The shaft of the first bevel gear is connected to a shaft head. A square insert is fixedly provided at the middle position of the upper end face of the shaft head. A lifting threaded rod is provided on the outer side of the top end of the square insert and connected to the metal column by a threaded structure. A square slot is provided at the middle position of the lower end face of the lifting threaded rod, and the square insert is inserted into the interior of the square slot.

[0008] A piston head is fixedly provided at the middle position of the upper end face of the lifting threaded rod, and a piston groove is provided on the outer side of the piston head, which is located at the middle position of the upper end face of the arc-shaped rubber reinforcement head and extends through the arc-shaped rubber reinforcement head into the interior of the metal column.

[0009] Preferably, a first clamping cylinder is fixedly installed on both sides of the outer surface of the clamping platform. The piston rod of the first clamping cylinder is connected to a side clamping plate, and an arc-shaped rubber fixing block is fixedly installed on the opposite surfaces of the two side clamping plates.

[0010] Preferably, both ends of the second gear shaft are located inside the metal column housing, and the second gear shaft located inside the metal column housing is connected to the metal column by roller bearings.

[0011] Preferably, the rotating head is located on the lower side inside the metal column, and the rotating head is connected to the metal column by a roller bearing.

[0012] Preferably, the inner wall of the square slot has a square cross-sectional shape, the outer surface of the square insert is in contact with the inner wall of the square slot, and the square insert and the square slot are slidably connected.

[0013] Preferably, a strip-shaped cover plate is provided below the two second clamping cylinders on the lower end face of the clamping platform, and the clamping platform and the strip-shaped cover plate are fixed together by screws.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention involves placing a low-hardness roller between two arc-shaped rubber fixing blocks when using equipment to fix it. A first clamping cylinder then pushes the arc-shaped rubber fixing blocks towards the roller. Once the two arc-shaped rubber fixing blocks are in contact with both sides of the roller's outer surface, lifting the roller into the air, the first clamping cylinder is closed. It is important to avoid applying excessive pressure to the roller at this point; simply lifting it into the air is sufficient to prevent deformation due to external pressure. After the roller is lifted into the air, a second clamping cylinder uses suction to fix the arc-shaped rubber reinforcement head to the lower end face of the roller, thus reinforcing it. This technical solution provides additional fixing points to the roller, enabling stable fixing of the roller with reduced clamping force, thereby reducing the possibility of deformation of low-hardness rollers.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The clamping platform 1 (model R35390), the first clamping cylinder 2 (model SC32), and the gear 20 (model 12A) mentioned in this utility model can all be obtained from the market or through private customization.

[0023] Please see Figures 1 to 4 An embodiment of this utility model is provided: a roller processing positioning and clamping device, including a clamping table 1, with a second clamping cylinder 5 fixedly installed on both sides of the middle position inside the clamping table 1, the piston rod of the second clamping cylinder 5 being connected to a metal column 6, and an arc-shaped rubber reinforcing head 7 being fixedly connected to the upper end face of the metal column 6.

[0024] A gear rack 21 is fixed inside the clamping platform 1 behind the metal column 6. The gear rack 21 meshes with a gear 20. The shaft of the gear 20 is connected to a second gear shaft 19. A fourth bevel gear 18 is fixedly sleeved on one side of the outer surface of the second gear shaft 19. The fourth bevel gear 18 meshes with a third bevel gear 17. The shaft of the third bevel gear 17 is connected to a first gear shaft 16. A second bevel gear 15 is fixedly sleeved on one side of the outer surface of the first gear shaft 16. The second bevel gear 15 meshes with a first bevel gear 14. The shaft of the first bevel gear 14 is connected to a shaft head 13. A square insert rod 12 is fixedly provided at the middle position of the upper end face of the shaft head 13. A lifting threaded rod 10 is provided on the outer side of the top end of the square insert rod 12 and is connected to the metal column 6 by a threaded structure. A square slot 11 is provided at the middle position of the lower end face of the lifting threaded rod 10, and the square insert rod 12 is inserted into the interior of the square slot 11.

[0025] A piston head 9 is fixedly provided at the middle position of the upper end face of the lifting threaded rod 10. A piston groove 8 is provided on the outer side of the piston head 9, located at the middle position of the upper end face of the arc-shaped rubber reinforcing head 7 and extending through the arc-shaped rubber reinforcing head 7 into the interior of the metal column 6.

[0026] A first clamping cylinder 2 is fixedly installed on both sides of the outer surface of the clamping table 1. The piston rod of the first clamping cylinder 2 is connected to the side clamping plate 3. An arc-shaped rubber fixing block 4 is fixedly installed on the opposite side of the two side clamping plates 3. When using the equipment to fix a roller with low hardness, the roller is placed between the two arc-shaped rubber fixing blocks 4. Then, the first clamping cylinder 2 pushes the arc-shaped rubber fixing blocks 4 toward the roller. When the two arc-shaped rubber fixing blocks 4 are respectively attached to the two sides of the outer surface of the roller and can lift the roller into the air, the first clamping cylinder 2 is closed. At this time, it is important to note that excessive squeezing force should not be applied to the roller. It is enough to lift the roller into the air and prevent it from shaking, so as to avoid deformation of the roller.

[0027] Both ends of the second gear shaft 19 are located inside the outer shell of the metal column 6, and the second gear shaft 19 inside the outer shell of the metal column 6 is connected to the metal column 6 by roller bearings; when the roller is lifted into the air, the second clamping cylinder 5 is activated to push the metal column 6 and the arc-shaped rubber reinforcing head 7 fixed to the upper end face of the metal column 6 upward. During the upward movement of the metal column 6, the second gear shaft 19 connected to it and the gear 20 fixedly sleeved on the outer surface of the second gear shaft 19 will move upward together. The upward moving gear 20 will roll along the tooth row 21. Under the transmission of the gear structure, the gear 20 rolling along the tooth row 21 will rotate continuously. The first gear 16 can rotate together with the second gear shaft 19 connected to the shaft of the gear 20 and the fourth bevel gear 18 fixedly sleeved on the outer surface of the second gear shaft 19. The rotating fourth bevel gear 18 can drive the third bevel gear 17 meshing with it and the first gear shaft 16 connected to the shaft of the third bevel gear 17 to rotate together. When the first gear shaft 16 rotates, the second bevel gear 15 fixedly sleeved on the outer surface of the first gear shaft 16 and the first bevel gear 14 meshing with it will rotate synchronously. The rotating first bevel gear 14 can drive the shaft head 13 connected to the shaft of the first bevel gear 14 and the square insert rod 12 fixed on the upper end face of the shaft head 13 to rotate together.

[0028] The inner wall of the square slot 11 has a square cross-section. The outer surface of the square insert rod 12 is in contact with the inner wall of the square slot 11, and the square insert rod 12 and the square slot 11 are slidably connected. Since the outer surface of the square insert rod 12 is in contact with the inner wall of the square slot 11 located at the lower end face of the lifting thread rod 10, when the square insert rod 12 rotates, the lifting thread rod 10 will rotate along with it. Under the transmission of the thread structure, the rotating lifting thread rod 10 can move up and down. When the metal column 6 moves upward, the lifting thread rod 10 will move downward. During the downward movement of the lifting thread rod 10, the piston head 9 fixed to the upper end face of the lifting thread rod 10 will move downward along with it. When the piston head 9 moves downward inside the piston groove 8, it will generate an adsorption force.

[0029] When the upper end face of the arc-shaped rubber reinforcing head 7 is in contact with the lower end face of the roller, the suction force generated by the piston head 9 moving downward inside the piston groove 8 can tightly fix the arc-shaped rubber reinforcing head 7 to the lower end face of the roller, thereby reinforcing the roller. The above technical solution can apply additional fixing points to the roller, thereby fixing the roller stably while reducing the clamping force applied to the roller, thereby reducing the possibility of deformation of the roller with low hardness.

[0030] The rotating head 13 is located on the lower side inside the metal column 6, and the rotating head 13 is connected to the metal column 6 by a roller bearing; the roller bearing structure between the rotating head 13 and the metal column 6 can ensure the stability of the rotating head 13.

[0031] Below the two second clamping cylinders 5, there is a strip-shaped cover plate located on the lower end face of the clamping table 1, and the clamping table 1 and the strip-shaped cover plate are fixed together by screws; the strip-shaped cover plate can protect the internal structure of the clamping table 1, and when the internal structure of the clamping table 1 fails, the strip-shaped cover plate can be removed to repair the internal structure of the clamping table 1.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
