Technical Field
[0001] The utility model belongs to the technical field of polishing cloth wheel processing, in particular to a punching device for polishing cloth wheels. Background Art
[0002] Polishing cloth wheel refers to a mechanical wheel used for polishing, which is made of cloth as the main material. It is one of the commonly used materials for polishing machines. Polishing cloth wheels are generally cut from twill cotton cloth or plain cotton cloth and sewn with strong sewing. They have relatively strong grinding force and are usually used for medium grinding or even polishing. However, their use also depends on the material of the workpiece and the quality requirements of the product.
[0003] During the production of the existing polishing cloth wheel, it is necessary to drill holes in the cut stacked cloth pieces for installation on the rotating shaft of the grinding and polishing machine. At present, the drilling of the polishing cloth wheel generally relies on the experience of the workers to drill with a handheld drill. This prevention not only easily leads to the drilled holes being skewed and uneven, but also the stacked cloth pieces are easily misaligned due to the multi-layer covering, resulting in the cloth pieces being entangled on the drill bit, which brings great trouble to the workers. Therefore, we propose a punching device for the production of polishing cloth wheels. Utility Model Content

[0007] As a preferred technical solution of the utility model, fixed seats are arranged on both sides of the top of the workbench, electric push rods are installed on the fixed seats, and the output ends of the electric push rods are connected to push plates.
[0008] As a preferred technical solution of the utility model, a card tray is arranged under the workbench. The card tray is arranged in two groups and is located opposite to each other on both sides of the center hole. A collecting trough is detachably installed under the workbench. Extended ribs are arranged on both sides of the collecting trough, and the extended ribs are slidably plugged into and adapted to the card tray.
[0009] As a preferred technical solution of the present invention, the bracket is arranged in an L-shaped structure.
[0010] As a preferred technical solution of the present invention, the card holder is arranged in an L-shaped structure.
[0011] Compared with the prior art, the utility model adopts the above structure to achieve the following beneficial effects: through the matching arrangement of the limit plate and the clamping plate on the outside of the drill rod, the support is driven to rise and fall through the sleeve block under the action of the rotation of the thread, the support drives the drilling motor and the drill rod to rise and fall to drill, and the electric telescopic rod under the support drives the limit plate and the clamping plate to descend and press on the stacked cloth pieces during drilling. When the drill rod continues to descend to drill, the spring between the limit plate and the clamping plate is continuously compressed, and the pressure on the stacked cloth pieces becomes relatively larger, which effectively prevents the stacked cloth pieces from being dislocated during the drilling process and improves the drilling efficiency.

A spring 14 is evenly connected between the clamping plate 13 and the limit plate 11. A through hole 15 is penetrated at the center of the clamping plate 13 and the limit plate 11. The drill rod 9 is penetrated through the through hole 15 without contact. Under the action of the rotation of the thread, the bracket 7 is driven to move up and down through the sleeve block 6. The bracket 7 drives the drilling motor 8 and the drill rod 9 to move up and down for drilling. The electric telescopic rod 10 under the bracket 7 drives the limit plate 11 and the clamping plate 13 to descend and press on the stacked cloth pieces when drilling.

Extended ribs 24 are arranged on both sides of the collecting trough 23. The extended ribs 24 are slidably plugged and adapted to the tray 22. The collecting trough 23 collects waste materials dropped from the center hole 3 after drilling.
[0024] During specific use, the stacked cloth pieces are placed on the workbench 1, the hole to be punched is aligned with the center hole 3, and then the electric push rod 20 is started. The electric push rod 20 drives the push plate 21 to telescopically move, and the two groups of push plates 21 push the stacked cloth pieces neatly, the driving motor 16 and the drilling motor 8 are turned on, and the driving motor 16 drives the threaded rod 17 to rotate, and under the threaded transmission action of the threaded rod 17, the sleeve block 6 is driven to descend on the guide rail 18, and the sleeve block 6 drives the bracket 7 to descend, and the bracket 7 drives the drilling motor 8 and the drill rod 9 to descend to drill holes. At the same time, the electric telescopic rod 10 under the bracket 7 drives the limit plate 11 and the clamping plate 13 to descend and press on the stacked cloth pieces during drilling. When the drill rod 9 continues to descend to drill, the spring 14 between the limit plate 11 and the clamping plate 13 is continuously compressed, and the pressure on the stacked cloth pieces becomes relatively large, and the waste material drilled by the drill rod 9 on the stacked cloth pieces falls into the collecting trough 23 through the center hole 3.
[0025] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto.
