Description

Technical Field

[0001] This utility model relates to the field of grinding machines, and in particular to a drum-type grinding machine with an adjustment mechanism. Background Technology

[0002] Rotary drum grinding machines are commonly used equipment in the grinding process. They grind workpieces by rotating drums to achieve the required surface precision and smoothness. In a rotary drum grinding machine, the support frame is a crucial component, serving to fix and support the workpiece, ensuring its stable operation during the grinding process.

[0003] However, in existing technologies, when a workpiece is placed on a support for grinding, the workpiece and the support are in direct contact, and this contact is frictional. During the grinding process, as the workpiece moves, a continuous frictional force is generated between the workpiece and the support. Due to this frictional contact, both the workpiece and the support are prone to wear during long-term use. Wear on the workpiece affects its machining accuracy and surface quality, leading to product defects; wear on the support reduces its support stability and service life, increases equipment maintenance costs and downtime, and seriously affects production efficiency. Therefore, this application proposes a drum-type grinding machine with an adjustment mechanism to solve the above problems. Utility Model Content

[0004] The main objective of this invention is to provide a drum-type grinding machine with an adjustment mechanism, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A drum-type grinding machine with an adjustment mechanism includes a grinding assembly. Two workpiece support frames are symmetrically fixedly mounted on the grinding assembly. An adjustment assembly is rotatably mounted on the workpiece support frames. Two support assemblies are symmetrically mounted on both sides of the workpiece support frames and on the adjustment assemblies. Each support assembly consists of a base plate and a cylinder. The cylinder is fixedly inserted into the base plate. A plurality of contact assemblies are horizontally and evenly mounted on the base plate and the workpiece support frames. Each contact assembly consists of a support rod, a connecting support frame, an annular shell, and ball bearings. The connecting support frame is fixedly mounted on the inner end of the support rod. The annular shell is fixedly mounted on the connecting support frame. The ball bearings are rotatably mounted inside the annular shell.

[0006] Preferably, the grinding assembly is fixedly installed on the upper end of the equipment base.

[0007] Preferably, the workpiece support frame consists of a U-shaped box and a support arm. The support arm is fixedly installed at the lower end of the U-shaped box and is also fixedly installed on the grinding assembly. Several mounting holes are symmetrically opened on both sides of the U-shaped box.

[0008] Preferably, the adjustment assembly consists of a bidirectional lead screw, retaining rings, and handles. The bidirectional lead screw is rotatably installed in mounting holes opened on both sides of the U-shaped box. There are two retaining rings that are symmetrically fixedly sleeved on the bidirectional lead screw and the retaining rings are in contact with the inner wall of the U-shaped box. There are two handles that are symmetrically fixedly installed at both ends of the bidirectional lead screw and the handles are located on the outside of the U-shaped box.

[0009] Preferably, the cylinder on the support assembly has a threaded hole, and the cylinder is mounted on the bidirectional lead screw on the adjustment assembly through the threaded hole.

[0010] Preferably, the support rod on the contact assembly is fixedly mounted on the base plate by a nut, and the support rod is simultaneously movably inserted into the mounting holes opened on both sides of the U-shaped box. The connecting support frame, the annular shell, and the ball bearings are all located inside the U-shaped box.

[0011] Compared with the prior art, the present invention has the following beneficial effects: By setting an adjustment component on the workpiece support frame, and a support component consisting of a base plate and a cylinder on the adjustment component, and a contact component consisting of a support rod, a connecting support frame, an annular shell, and ball bearings on the workpiece support frame and the support component, the workpiece is placed on the ball bearings of the contact component during workpiece processing. The ball bearings can rotate within the annular shell, thereby transforming the frictional contact between the workpiece and the support structure into rolling contact, significantly reducing friction. This effectively reduces wear on the workpiece and support structure during long-term use, ensuring the workpiece's processing accuracy and surface quality, improving the support structure's support stability and service life, reducing equipment maintenance costs and downtime, and increasing production efficiency. Simultaneously, rotating the handle drives the bidirectional lead screw to rotate, and the threaded engagement causes the cylinder to move the base plate on the bidirectional lead screw, thereby adjusting the distance between the two relative contact components. This allows the contact components to adapt to the support requirements of workpieces with different diameters, improving the versatility and applicability of the contact components.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Please see Figures 1-4 As shown, a drum-type grinding machine with an adjustment mechanism includes a grinding assembly 1. Two workpiece support frames 2 are symmetrically fixedly mounted on the grinding assembly 1. An adjustment assembly 3 is rotatably mounted on the workpiece support frames 2. Two support assemblies 4 are symmetrically mounted on both sides of the workpiece support frames 2 and on the adjustment assembly 3. Each support assembly 4 consists of a base plate 13 and a cylinder 14. The cylinder 14 is fixedly inserted into the base plate 13. A plurality of contact assemblies 5 are horizontally and evenly mounted on the base plate 13 and the workpiece support frames 2. Each contact assembly 5 consists of a support rod 16, a connecting support frame 17, an annular shell 18, and ball bearings 19. The connecting support frame 17 is fixedly mounted on the inner end of the support rod 16, the annular shell 18 is fixedly mounted on the connecting support frame 17, and the ball bearings 19 are rotatably mounted inside the annular shell 18. By setting the adjustment assembly 3 on the workpiece support frame 2 and the support assembly 4 composed of the base plate 13 and the cylinder 14 on the adjustment assembly 3, the grinding assembly 16 and the support assembly 4 are symmetrically mounted on the workpiece support frame 2 and the workpiece support frame 2 are symmetrically mounted on the adjustment assembly 3. The support assembly 4 is equipped with a contact assembly 5 consisting of a support rod 16, a connecting support frame 17, an annular shell 18, and ball bearings 19. When processing a workpiece, the workpiece is placed on the ball bearings 19 of the contact assembly 5. The ball bearings 19 can rotate within the annular shell 18, thereby converting the frictional contact between the workpiece and the support structure into rolling contact, significantly reducing friction. This effectively reduces wear on the workpiece and support structure during long-term use, ensuring the processing accuracy and surface quality of the workpiece, improving the support stability and service life of the support structure, reducing equipment maintenance costs and downtime, and increasing production efficiency. At the same time, rotating the handle 12 can drive the bidirectional lead screw 10 to rotate. The threaded engagement causes the cylinder 14 to move the base plate 13 on the bidirectional lead screw 10, thereby adjusting the distance between the two relative contact assemblies 5. This allows the contact assembly 5 to adapt to the support requirements of workpieces with different diameters, improving the versatility and applicability of the contact assembly 5.

[0016] Specifically, the grinding assembly 1 is fixedly installed on the upper end of the equipment base 6. The workpiece support frame 2 consists of a U-shaped box 7 and a support arm 8. The support arm 8 is fixedly installed on the lower end of the U-shaped box 7 and is also fixedly installed on the grinding assembly 1. Several mounting holes 9 are symmetrically opened on both sides of the U-shaped box 7. The adjusting assembly 3 consists of a bidirectional lead screw 10, a retaining ring 11, and a handle 12. The bidirectional lead screw 10 is rotatably installed in the mounting holes 9 opened on both sides of the U-shaped box 7. There are two retaining rings 11, which are symmetrically fixedly sleeved on the bidirectional lead screw 10, and the retaining rings 11 are in contact with the inner wall of the U-shaped box 7. Two handles 12 are symmetrically fixedly installed at both ends of the bidirectional lead screw 10, and the handles 12 are located on the outside of the U-shaped box 7. A threaded hole 15 is provided on the cylinder 14 of the support assembly 4. The cylinder 14 is installed on the bidirectional lead screw 10 of the adjusting assembly 3 through the threaded hole 15. The support rod 16 on the contact assembly 5 is fixedly installed on the base plate 13 by a nut. The support rod 16 is simultaneously movably inserted into the mounting holes 9 opened on both sides of the U-shaped box 7. The connecting support frame 17, the annular shell 18, and the ball bearing 19 are all located inside the U-shaped box 7. When using this drum-type grinder with an adjusting mechanism, first... Adjust the distance between the two contact components 5 according to the workpiece diameter. First, rotate the handle 12 on the adjusting component 3. The handle 12 drives the bidirectional lead screw 10 to rotate in the mounting hole 9. Because the cylinder 14 on the support component 4 is installed on the bidirectional lead screw 10 through the threaded hole 15, and the retaining ring 11 contacts the inner wall of the U-shaped box 7 to restrict the axial movement of the bidirectional lead screw 10, when the bidirectional lead screw 10 rotates, the cylinder 14 drives the base plate 13 to move on the bidirectional lead screw 10 through the threaded engagement. When the base plate 13 moves, the support rod 16 on the contact component 5 slides in the mounting holes 9 on both sides of the U-shaped box 7. The distance between the two opposing contact components 5 is adjusted by moving the contact components 5 to adapt to the support requirements of workpieces with different diameters. After adjustment, the workpiece is processed by placing it on the ball bearing 19 of the contact component 5, and then starting the grinding component 1 and pushing the workpiece into the grinding component 1. As the workpiece moves, the ball bearing 19 on the contact component 5 will rotate in the annular shell 18, so that the workpiece and the support structure are in rolling contact, which reduces the frictional resistance between the workpiece and the support structure, ensures the smooth grinding process of the workpiece, and effectively reduces the wear of the workpiece and the support structure.

[0017] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
