Description

Technical Field

[0001] This utility model relates to the field of friction disc processing technology, and more specifically, to an automatic lathe for producing polyurethane friction discs. Background Technology

[0002] Polyurethane friction discs are friction discs made of polyurethane material, possessing numerous superior properties. During the processing of polyurethane friction discs, they require positioning and conveying between two processing machines. Existing automatic conveyor machines typically use vacuum suction or gripping methods for clamping and then transferring. However, because the friction discs are stacked and relatively small, the stability of vacuum suction or gripping methods is poor, easily leading to stacking collapse or falling. Therefore, we propose an automatic lathe for the production of polyurethane friction discs. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an automatic lathe for the production of polyurethane friction discs, so as to solve the technical problem of poor fixed stability of current conveyor machines.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an automatic lathe for producing polyurethane friction discs, including a grounding frame, a moving rail installed on the top of the grounding frame, an upper fixed frame arranged on the moving rail, a lower fixed frame arranged below the upper fixed frame, a lifting cylinder installed between the upper fixed frame and the lower fixed frame, a plurality of constraint shells arranged at the bottom of the lower fixed frame, an expansion structure arranged at the bottom center of the constraint shell, side clamping structures arranged on both sides of the constraint shell, and a driving structure installed at the top center of the constraint shell.

[0005] Preferably, the expansion structure includes a fixing plate fixed to the top of the constraint shell, and a plurality of support blocks arranged in a circular array below the fixing plate. A sliding block is provided between the top of the support block and the bottom of the fixing plate for limiting sliding, and a spring is provided on one side of the sliding block.

[0006] Preferably, a slope block is installed on the inner side of the support block, the top of the slope block is an arc surface design, and a pressure head is provided between multiple slope blocks.

[0007] Preferably, the side clamp structure includes a rotating gear located outside the constraint shell, the center of the rotating gear being rotatably connected to an extension plate fixed to the outside of the constraint shell, a bent handle being eccentrically mounted on the rotating gear, and an arc clamp being mounted at the bottom end of the bent handle.

[0008] Preferably, the driving structure includes a driving cylinder, the driving end of which is connected to a connecting column, and the bottom end of the connecting column passes through a fixing plate and is connected to a pressure head.

[0009] Preferably, drive gears are provided on both sides of the drive end of the drive cylinder, the drive gears mesh with the rotating gears, and a connecting rod is hinged between the eccentric position of the two drive gears and the end of the drive end of the drive cylinder.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model uses a ring array of multiple support blocks and the cooperation between the slope block and the pressure head, and the cooperation between the sliding block and the spring, to enable the support blocks to automatically reset. Combined with the cooperation between the bent handle and the arc clamp and the rotation of the rotating gear, the expansion of the support blocks can be fixed to the inner circumference of the friction disk, and the rotation of the arc clamp can clamp the outer circumference of the friction disk, thereby achieving double fixation and solving the problem of poor fixation stability of the conveyor machine tool.

[0012] 2. This utility model also achieves two-layer clamping action through the operation of the cylinder and the fixing of the connecting column and the pressure head, and through the linkage between the connecting rod, the drive gear, the connecting column and the cylinder. When the cylinder is running, the support block will first open and fix the inside of the friction disk. Then the arc clamp will clamp the outer periphery of the friction disk. This allows the cylinder to achieve two-layer clamping action. The design of opening and fixing the inner periphery first can play a positioning role for the rear clamping and fixation, making the clamping more stable and further solving the problem of poor fixing stability of the conveyor tool.

[0021] like Figures 1 to 4 As shown, this utility model relates to an automatic lathe for producing polyurethane friction discs, including a grounding frame 1. A moving rail 2 is mounted on the top of the grounding frame 1. The moving rail 2 can be an existing linear motor, etc. An upper fixed frame 3 is provided on the moving rail 2, and a lower fixed frame 4 is provided below the upper fixed frame 3. A lifting cylinder 5 is installed between the upper fixed frame 3 and the lower fixed frame 4. The specifications and number of the lifting cylinder 5 are selected according to the situation. Several constraint shells 6 are provided at the bottom of the lower fixed frame 4. An expansion structure 7 is provided at the center of the bottom of the constraint shell 6. The expansion structure 7 includes a fixing plate 701 fixed to the top of the constraint shell 6. Several support blocks 702 arranged in a circular array are provided below the fixing plate 701. The support blocks 702 are made of a specific elastic material. Preferably made of rubber, a sliding block 703 is provided between the top of the support block 702 and the bottom of the fixing plate 701 for limiting sliding. A spring 704 is provided on one side of the sliding block 703. The elasticity of the spring 704 plays the role of restoring the support block 702 after it is opened. A slope block 705 is installed on the inner side of the support block 702. The top of the slope block 705 is designed with an arc surface. A pressure head 706 is provided between multiple slope blocks 705. A drive structure 9 is installed at the top center of the constraint shell 6. The drive structure 9 includes a drive cylinder 901. The drive cylinder 901 has multiple air ports. The multiple air ports are connected to an external air source. A connecting column 902 is connected to the drive end of the drive cylinder 901. The bottom end of the connecting column 902 passes through the fixing plate 701 and is connected to the pressure head 706.

[0022] The second layer of fixing includes side clamping structures 8 on both sides of the constraint shell 6. The side clamping structures 8 include a rotating gear 801 located on the outside of the constraint shell 6. The center of the rotating gear 801 is rotatably connected to an extension plate 802 fixed to the outside of the constraint shell 6. A bent handle 803 is eccentrically mounted on the rotating gear 801. An arc clamp 804 is mounted at the bottom end of the bent handle 803. The drive structure 9 also includes a drive gear 903 and a connecting rod 904. Both sides of the drive end of the drive cylinder 901 are provided with drive gears 903, which mesh with the rotating gear 801.

[0023] It is worth mentioning that, in order to achieve synchronous operation, a connecting rod 904 is hinged between the eccentric position of the two drive gears 903 and the end of the drive cylinder 901.

[0024] Working principle: When needed, the lower frame 4 descends to the clamping position. At this time, an external air source is input, driving the cylinder 901 to run. The drive end moves down. During the downward movement, the connecting column 902 drives the pressure head 706 to descend, expanding the slope block 705 and causing the support block 702 to expand, thus internally supporting and fixing the inner ring of the friction disc. During the descent, the connecting rod 904 cooperates to rotate the drive gear 903, causing the rotating gear 801 to rotate, which in turn bends the handle 803, allowing the arc clamp 804 to clamp the outer circumference of the friction disc. (Due to the elastic design of the support block 702, the inner support can be fixed to a certain extent before clamping the outer circumference. To achieve adjustment, the connection position of the handle 803 can be adjusted according to the size of the friction disc.)

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
