Description

Technical Field

[0001] The utility model relates to the technical field of grinding mechanisms, in particular to a grinding mechanism for pulley processing. Background Technique

[0002] Pulleys belong to disc hub parts, generally with relatively large dimensions. In manufacturing processes, casting and forging are mainly used. Pulleys are mainly used in occasions for transmitting power over long distances.

[0003] During the processing and production of existing pulleys, a grinding mechanism is required to grind the surface of the pulley to smooth the burrs on the pulley surface. However, when the existing grinding mechanism is in use, generally the pulley is clamped and fixed, and then ground by a corresponding grinding wheel or grinding block. It cannot grind pulleys with different sizes or different pulley grooves, and the use effect is poor. Moreover, when the existing grinding mechanism is working, the debris generated by grinding will scatter in the surrounding environment, polluting the environment and requiring subsequent cleaning by staff, which is inconvenient. For this reason, we propose a grinding mechanism for pulley processing. Content of the Utility Model

[0004] The purpose of the utility model is to solve the above-mentioned disadvantages in the prior art, and to propose a grinding mechanism for pulley processing.

The second opening groove is sleeved on the lead screw. And the adjacent ends of each pair of adjusting nuts abut against the side surface of the fixing plate;

[0007] Legs are installed at the bottom edge of the base. A storage plate is installed between the legs. A slag collection box is arranged on the top of the storage plate. A slag discharge groove is opened on the top of the base. The top opening of the slag collection box is located below the slag discharge groove;

[0008] On both sides of the slag discharge groove, through grooves are provided at the top of the base. Inside each through groove, a baffle is provided. Both ends of the baffle extend outside the through groove. At both ends of the side surface of each baffle, there is a clearance fit with the edge of the U-shaped frame. And at one side of the bottom of each baffle, a strip-shaped connecting plate is extended. The bottom of the strip-shaped connecting plate is connected to the storage plate through a first telescopic mechanism.

[0009] Preferably, at least one guide rod is vertically installed on the top of the strip-shaped moving plate. The top of the guide rod slidably penetrates through the top of the U-shaped frame.

Specific embodiments

[0023] 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 the embodiments.

[0024] Referring to Figures 1 - 4 , a grinding mechanism for pulley processing, including a base 15, a U-shaped frame 7 is installed on the top of the base 15, a control cabinet 26 is installed on one side of the U-shaped frame 7, a controller is provided in the control cabinet 26, and the controller is one of a control main board, a host or a PLC logic controller. One end of the rotating shaft 19 is connected to the drive motor 5, the drive motor 5 is fixed on the side wall of the U-shaped frame 7, the drive motor 5 is connected to the controller through a wire, and a chuck 14 is installed at the other end of the rotating shaft 19. A pulley is fixed on the chuck 14. The chuck 14 is one of a three-jaw chuck, a four-jaw chuck or a five-jaw chuck. The pulley to be ground can be clamped and fixed by the chuck 14, and then the pulley is driven to rotate by the drive motor 5 to facilitate subsequent grinding.

[0025] As Figure 1 shown, a strip-shaped moving plate 10 is provided inside the U-shaped frame 7. The top of the strip-shaped moving plate 10 is connected to the U-shaped frame 7 through a second telescopic mechanism 8. The second telescopic mechanism 8 is connected to the controller through a wire. In the actual use process, the movement of the strip-shaped moving plate 10 can be controlled by the second telescopic mechanism 8, and then the strip-shaped moving plate 10 can be adjusted to a preset position by the second telescopic mechanism 8 when needed.

[0026] As Figure 2 and Figure 4As shown in the figure, a U-shaped seat 21 is installed at the bottom of the strip-shaped moving plate 10. A lead screw 13 is fixedly installed between the U-shaped seats 21. A number of pairs of adjusting sleeves 23 are threadedly connected to the lead screw 13. A fixing plate 11 is provided between each pair of adjusting sleeves 23. A grinding block 12 is installed at the bottom of the fixing plate 11. The grinding block 12 is aligned with the pulley groove. A second opening groove 24 is formed on one side of the fixing plate 11. The second opening groove 24 is sleeved on the lead screw 13. And the adjacent ends of each pair of adjusting sleeves 23 abut against the side surface of the fixing plate 11. During actual use, the staff can place the fixing plate 11 at the corresponding position on the lead screw 13 according to the position of the pulley groove to be ground, so that the grinding block 12 is aligned with the pulley groove. Then rotate the adjusting sleeve 23 so that each pair of adjusting sleeves 23 clamp and fix the fixing plate 11, and the fixation can be completed. In this way, during grinding, the position of the grinding block 12 can be adjusted according to the position of the groove on different pulleys, improving the use effect.

[0027] It should be noted that a limiting rod 20 is also installed between the U-shaped seats 21. The limiting rod 20 is located above the lead screw 13. And a first opening groove 22 is formed on one side of the fixing plate 11. The first opening groove 22 is sleeved on the limiting rod 20. With the cooperation of the limiting rod 20 and the first opening groove 22, the fixing plate 11 can be limited to prevent the fixing plate 11 from rotating along the lead screw 13.

[0028] As Figure 1 and Figure 3 As shown in the figure, legs 16 are installed at the bottom edge of the base 15. A storage plate 1 is installed between the legs 16. A slag collection box 17 is provided on the top of the storage plate 1. A slag discharge groove 18 is formed on the top of the base 15. The top opening of the slag collection box 17 is located below the slag discharge groove 18. During actual use, the debris generated during the grinding process will pass through the slag discharge groove 18 and fall into the slag collection box 17 for collection, preventing the debris from scattering into the surrounding environment.

[0029] As Figure 1 and Figure 3 As shown in the figure, through grooves 25 are formed on both sides of the slag discharge groove 18 on the top of the base 15. A baffle 4 is provided inside each through groove 25. Both ends of the baffle 4 extend outside the through groove 25. The two ends of the side surface of each baffle 4 are in clearance fit with the edge of the U-shaped frame 7. And a strip-shaped connecting plate 3 is extended and provided at the bottom side of each baffle 4. The bottom of the strip-shaped connecting plate 3 is connected to the storage plate 1 through a first telescopic mechanism 2. The first telescopic mechanism 2 is connected to the controller through a wire. During actual use, when the pulley needs to be ground, the staff can control the first telescopic mechanism 2 to extend through the controller, which can push the baffle 4 to move upward to block the openings on both sides of the U-shaped frame 7. In this way, during grinding, the debris generated during the grinding process will not scatter into the surrounding environment.

[0030] It should be noted that the top edge of the slag collecting box 17 is in clearance fit with the bottom of the base 15, and the adjacent surfaces of the two baffles 4 are in clearance fit with the side surface of the slag collecting box 17. During actual use, the debris generated during the grinding process will be blocked by the baffle 4 and fall into the slag collecting box 17 under the action of gravity. The debris will not leak from the gap between the base 15 and the slag collecting box 17, nor will it leak from the gap between the baffle 4 and the slag collecting box 17.

[0031] Among them, both the first telescopic mechanism 2 and the second telescopic mechanism 8 are one of an electric push rod, a cylinder or a hydraulic rod.

[0032] Specifically, when the present utility model is in use, the staff first fixes the pulley on the chuck 14, and then sleeved the fixing plate 11 with the grinding block 12 on the lead screw 13, so that the grinding block 12 is aligned with the pulley groove. Then rotate the adjusting nut 23 so that each pair of adjusting nuts 23 clamp and fix the corresponding fixing plate 11. Then control the first telescopic mechanism 2 to extend through the controller. The first telescopic mechanism 2 pushes the baffle 4 upward to block the two openings on both sides of the U-shaped frame 7. Then the staff controls the driving motor 5 and the second telescopic mechanism 8 to work. The driving motor 5 drives the pulley to rotate. At the same time, the second telescopic mechanism 8 pushes the grinding block 12 downward to contact the surface of the pulley for grinding the pulley. The debris generated during the grinding process will collide with the baffle 4 under the action of inertia, and then the debris will fall into the lower slag collecting box 17 under the action of gravity for collection. After the grinding is completed, the staff closes the driving motor 5 through the controller and at the same time controls the first telescopic mechanism 2 and the second telescopic mechanism 8 to contract. The baffle 4 moves downward to open the two openings on both sides of the U-shaped frame 7. At the same time, the pulley stops rotating, and the grinding block 12 disengages from the surface of the pulley. The staff can remove the ground pulley.

[0033] Furthermore, as Figure 1 shown, at least one guide rod 9 is vertically installed on the top of the strip-shaped moving plate 10. The top of the guide rod 9 slidably penetrates through the top of the U-shaped frame 7. Under the action of the guide rod 9, the strip-shaped moving plate 10 can be limited to keep it stable.

[0034] Furthermore, as Figure 1 shown, guide rails 6 are installed on both edges of the U-shaped frame 7. Both ends of the side surface of the baffle 4 are slidably connected to the guide rails 6 through sliders. The baffle 4 can be guided by the guide rails 6 to keep it stable.

[0035] Furthermore, as Figure 1 shown, there is a distance between the adjacent surfaces of the two baffles 4 and the chuck 14 and the pulley. In this way, during actual use, the baffle 4 will not interfere with the chuck 14 and the pulley.

[0036] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
