Description

Technical Field

[0001] The utility model relates to the technical field of polishing machines, and more specifically, to a drum for a planetary roller grinding and polishing machine with a large capacity. Background Art

[0002] Existing centrifugal roller grinding and polishing machines all adopt a simple planetary motion mechanism, which decomposes the rotation of the motor so that the drum loaded with polishing parts rotates both around the sun and in the reverse direction of its own rotation, so that the polishing parts and the abrasive grinding fluid are ground against each other to achieve the polishing purpose. The axis of the drum coincides with the axis of its own rotation, and the directions of its own rotation and revolution are opposite, so that the workpieces and abrasive grains in the drum flow two-dimensionally in a forced manner, and under the action of centrifugal pressure, extrusion, friction, collision and other effects are generated to realize the polishing and grinding processing of the workpiece surface. However, the existing polishing machines generally only have multiple drums, and the capacity of the workpieces that can be cleaned is small.

[0003] For example, a planetary drum polishing machine disclosed in the Chinese utility model patent with the application number CN202020831556.6 includes: a frame; a driving device, which is arranged on the frame; a planetary reduction component, which is rotatably installed on the frame and is connected to the driving device; a drum, which is installed on the planetary reduction component; a control device, which includes an inverter and a PLC controller, the output end of the PLC controller is connected to the input end of the inverter, and the output end of the inverter is connected to the driving device. Although it can realize the polishing of workpieces, the capacity of this planetary drum polishing machine is small, and the types or capacity of the workpieces that can be cleaned are less.

[0004] Therefore, it is very necessary to propose a drum for a planetary roller grinding and polishing machine with a large capacity to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problems that the capacity of the planetary drum polishing machine is small, and the types or capacity of the workpieces that can be cleaned are less.

[0006] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0007] A drum for a planetary roller grinding and polishing machine with a large capacity includes a plurality of drums arranged on the planetary roller grinding and polishing machine, and at least four rows of material cylinders are arranged in each drum, and each row of material cylinders is provided with at least two.

[0008] Furthermore, the material cylinder is locked in the drum through a locking mechanism.

[0009] Furthermore, a handle is fixedly connected to the side surface of the material cylinder.

[0010] Furthermore, the material cylinder includes a cylinder body and an end cover detachably arranged on the cylinder body.

[0011] Furthermore, a second eccentric shaft is rotatably connected to the upper end of the cylinder, and a grip rod is fixedly connected to the second eccentric shaft.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model arranges a plurality of material barrels evenly distributed in the drum, thereby increasing the rotation radius of the workpiece in the drum, and also increasing the centrifugal force to make the workpiece more evenly stressed, thereby improving the production capacity.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1-3, A drum for a planetary roller grinding and polishing machine with a large capacity, including a drum 1 installed on the planetary roller grinding and polishing machine. Both ends of the drum 1 are fixedly connected with end shafts 2 for installation on the planetary roller grinding and polishing machine. The specific installation method is the prior art and will not be described further. At least four rows of material cylinders 7 (shown as six rows in the attached drawings) are arranged in each drum 1, and each row of material cylinders 7 has at least two. A handle 24 is fixedly connected to the side of the material cylinder 7. The material cylinder 7 includes a cylinder body and an end cover 25 detachably arranged on the cylinder body. A second eccentric shaft 26 is rotatably connected to the upper end of the cylinder body, and a grip rod 27 is fixedly connected to the second eccentric shaft 26. By rotating the grip rod 27, the second eccentric shaft 26 presses down the end cover 25. Anti-slip layers are provided on the outer side surface of the second eccentric shaft 26 and the upper end surface of the end cover 25 to increase the friction between the second eccentric shaft 26 and the end cover 25. A plurality of round tubes 3 are circumferentially and arrayedly distributed on the outer edge of the drum 1, and an opening 5 for installing the material cylinder 7 is reserved. That is, a plurality of material cylinders 7 are installed into the drum 1 through this opening 5 at one time. The end cover 25 of the material cylinder 7 can be opened to fill abrasive and workpieces. An inner baffle 6 is fixedly connected to the inner side surface of the round tube 3. A plurality of depressions for cooperating with the installation of the material cylinder 7 are provided on the inner baffle 6, and the overall shape is petal-shaped. The locking mechanism provided at the opening 5 squeezes the material cylinder 7 at the opening 5, so that the material cylinder 7 squeezes other material cylinders 7 and all the material cylinders 7 are temporarily fixed in the depressions to achieve the fixation of a plurality of material cylinders 7. The locking mechanism is correspondingly arranged according to the arrangement of the material cylinders 7.

[0020] Specifically, the locking mechanism includes a squeezing component for squeezing the material cylinder 7 at the opening 5 and a locking component for locking the squeezing component. The squeezing component is hinged to a first mounting plate 8 fixedly connected to the round tube 3 at one end of the opening 5, and the locking component is arranged on a second mounting plate 16 on the round tube 3 at the other end of the opening 5.

[0021] Specifically, the squeezing component includes an arc-shaped pressing member 9 rotatably connected to the first mounting plate 8, a squeezing block 23 fixedly connected to the side of the arc-shaped pressing member 9 facing the material cylinder 7, a squeezing compensation mechanism movably arranged in the middle of the arc-shaped pressing member 9, and a connecting component for cooperating with the locking component to lock. The squeezing block 23 is a rubber pad, which is elastic and has sufficient friction, and is arranged on the side of the squeezing plate 22 facing the material cylinder 7. The squeezing plate 22 is fixed to the side of the arc-shaped pressing member 9 facing the material cylinder 7. The squeezing block 23 facilitates the arc-shaped pressing member 9 to press the material cylinder 7 located at the opening 5, and the temporary fixation of the material cylinder 7 is achieved through the mutual squeezing between the material cylinders 7.

[0022] Specifically, the extrusion compensation mechanism includes a first eccentric shaft 10 eccentrically and rotatably connected to the middle of the arc-shaped pressing member 9, connecting plates 11 rotatably connected to both ends of the first eccentric shaft 10, and a connecting shaft 12 rotatably connected to one end of the connecting plate 11 away from the first eccentric shaft 10. A compensation through groove 13 is formed at one end of the arc-shaped pressing member 9 away from the first mounting plate 8. Both ends of the connecting shaft 12 are located in the compensation through groove 13 and do not fit against the inner side surface of the compensation through groove 13, so that the connecting shaft 12 can move in the compensation through groove 13. The connecting assembly is adjustably arranged in the connecting shaft 12. When the first eccentric shaft 10 rotates, it can drive the upper end of the connecting plate 11 to move upward, and at the same time, the lower end of the connecting plate 11 drives the connecting shaft 12 to move upward along the compensation through groove 13 to finely adjust the position of the connecting assembly.

[0023] Specifically, the connecting assembly includes a screw rod 14 inserted in the middle of the connecting shaft 12 and nuts 15 threadedly connected to the screw rod 14 at both ends of the connecting shaft 12. A plug hole matching the locking assembly is formed at one end of the screw rod 14 away from the first eccentric shaft 10. By simultaneously adjusting the relative positions of the two nuts 15, the distance between the plug hole and the connecting shaft 12 can be adjusted to facilitate the locking of the locking assembly.

[0024] Specifically, the locking assembly includes a U-shaped plate 17 fixedly connected to one side of the second mounting plate 16, a plug rod 18 slidably connected in the U-shaped plate 17, and a spring 19 sleeved outside the plug rod 18 on the inner side of the U-shaped plate 17. One end of the plug rod 18 penetrates through the middle of the U-shaped plate 17, and the other end penetrates through the middle of the second mounting plate 16 and can be inserted into the plug hole. One end of the spring 19 away from the middle of the U-shaped plate 17 is fixedly connected to the plug rod 18, so that when the plug rod 18 is pulled, the spring 19 can be compressed, and the other end of the plug rod 18 can be moved out of the plug hole.

[0025] Specifically, in order to facilitate the pulling of the plug rod 18, a pull handle 20 is fixedly connected to the plug rod 18 at one end in the middle of the U-shaped plate 17. By pulling the plug rod 18, the spring 19 is compressed, and then the plug rod 18 is pulled out of the plug hole to release the locking of the connecting assembly.

[0026] Specifically, in order to facilitate the opening of the locking assembly, a handle 21 is fixedly connected to the first eccentric shaft 10 to facilitate lifting the locking assembly.

[0027] Specifically, in order to ensure the safety of the planetary roller grinding and polishing machine during operation, an outer baffle 4 is fixedly connected to the outer side surface of the round tube 3.

[0028] Installation method: When installing the cartridge 7, place one cartridge 7 at a time into the corresponding recess from the opening 5. After placement, the operator holds the cartridge 7 at the opening 5 by hand, and then rotates the arc-shaped pressing member 9 by hand so that the extrusion block 23 can press against the cartridge 7. Then, the first eccentric shaft 10 can be rotated by holding the handle 21 to drive the screw rod 14 to move up and down to adjust the position of the insertion hole. At the same time, pull the pull handle 20 so that the insertion hole can correspond to the insertion rod 18. After correspondence, release the pull handle 20, and the insertion rod 18 can be inserted into the insertion hole to complete the fixation of the cartridge 7.

[0029] In addition, it is also possible to first insert the insertion rod 18 into the insertion hole, and then rotate the first eccentric shaft 10 downward to achieve the locking of multiple cartridges 7.
