Description

Technical Field

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

[0002] Polyurethane friction discs are friction discs made of polyurethane material, possessing numerous superior properties. During the manufacturing process, the outer ring of the friction disc requires precision grinding. This is typically done via robotic arms or manual labor to replace the friction disc components, resulting in lengthy replacement times, hindering continuous mechanized processing, and leading to low processing efficiency. Therefore, we propose a grinding lathe for polyurethane friction discs. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a lathe for grinding polyurethane friction discs to solve the technical problem of low processing efficiency.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a lathe for grinding polyurethane friction discs, including a grinding machine tool, clamping parts on both sides of the grinding machine tool, a grinding disc on the side of the grinding machine tool, a grinding motor connected to the grinding machine tool installed at the center of the grinding disc, a material feeding track between the two clamping parts, multiple friction discs flowing inside the material feeding track, a material feeding plate on the upper half of the material feeding track, two material feeding structures on the top of the material feeding plate, a belt drive between the two material feeding structures, and a curved plate at one end of the material feeding plate.

[0005] Preferably, the bottom of the clamping part moves via a linear track, and the clamping end of the clamping part has a pointed conical structure.

[0006] Preferably, the outer periphery of the conveying plate is in contact with the conveying track, and the bottom of the conveying plate is provided with multiple arc grooves that are in contact with the friction wheel.

[0007] Preferably, the feeding structure includes a fixed plate connected to the feeding track, a rotating disk rotatably connected to the fixed plate, a connecting rod plate eccentrically hinged to the rotating disk, and one end of the connecting rod plate hinged to the top of the feeding plate.

[0008] Preferably, the belt drive includes two pulleys and a belt, the belt being sleeved between the outer circumferences of the two pulleys, and a drive motor being connected to the center of one of the pulleys.

[0009] Preferably, the curved plate and the conveying track are rotatably connected, and an electromagnet is provided between the curved plate and the side of the conveying track that are in contact with each other.

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

[0011] 1. This utility model adapts and facilitates the flow of the friction disc through a material conveying track, and then uses a curved plate set in a clamping position. Combined with the bottom recess of the material conveying plate to engage and convey the friction disc, the movement of the material conveying plate can automatically convey and load the friction disc on the track. With the rotational connection of the curved plate and the design of electro-magnetic attraction, the polished friction disc can also be automatically unloaded, realizing automatic unloading and continuous feeding of the production line, thus solving the problem of low processing efficiency.

[0012] 2. This utility model also uses the eccentric hinge of two rotating disks and connecting rod plate, and the drive of the pulley can make the connecting rod plate drive the material conveying plate to move, realizing automatic feeding. When the hinge point between the connecting rod plate and the rotating disk is in the upper part, it will pull the material conveying plate up to separate from the friction disk and return to its original position, thus realizing a cycle, realizing continuous and stable feeding, and further solving the problem of low processing efficiency.

[0021] like Figures 1 to 5As shown, this utility model relates to a lathe for grinding polyurethane friction discs, including a grinding machine tool 1. The grinding machine tool 1 has clamping parts 2 on both sides. The bottom of the clamping parts 2 moves via a linear track. The clamping ends of the clamping parts 2 have a pointed conical structure. When not clamped, the distance between the two clamping parts 2 is approximately greater than the thickness of one friction disc. When clamping is required, the pointed conical design, combined with the movement of the clamping parts 2, constrains and fixes the center of the friction disc. A drive rotation component is installed inside the clamping parts 2, allowing the friction disc to rotate at high speed. Since the clamping parts 2 directly adopt existing grinding machine tool technology, they will not be described in detail here. A grinding disc 3 is provided on the side of the grinding machine tool 1. A grinding motor 4 connected to the grinding machine tool 1 is installed at the center of the grinding disc 3. A material conveying track 5 is provided between the two clamping parts 2. The inner circumference of the material conveying track 5 is the same as the thickness of the friction disc. The conveyor has multiple friction discs. The upper part of the conveyor track 5 is provided with a conveyor plate 6. The outer periphery of the conveyor plate 6 is in contact with the conveyor track 5. The bottom of the conveyor plate 6 has multiple arc grooves that are in contact with the friction wheels. The top of the conveyor plate 6 is provided with two material feeding structures 7. The material feeding structure 7 includes a fixed plate 701 connected to the conveyor track 5. A rotating disk 702 is rotatably connected to the fixed plate 701. A connecting rod plate 703 is eccentrically hinged to the rotating disk 702. One end of the connecting rod plate 703 is hinged to the top of the conveyor plate 6. The center of the rotating disk 702 is fixed with a central shaft that is rotatably connected to the two corresponding fixed plates 701. A belt drive 8 is provided between the two material feeding structures 7. The belt drive 8 includes two pulleys 801 and a belt 802. The belt 802 is sleeved between the outer peripheries of the two pulleys 801. The center of one pulley 801 is fixed to the outer periphery of the central shaft. One of the central shafts is connected to a drive motor 803.

[0022] To achieve automatic feeding and facilitate the next automatic loading, a curved plate 9 is provided at one end of the feeding plate 6. The curved plate 9 is rotatably connected to the feeding track 5. An electromagnet is provided between the contact side of the curved plate 9 and the feeding track 5. Through the design of electronic control, the electromagnet has magnetic attraction when energized, so that the curved plate 9 and the feeding track 5 are completely in contact. When there is no magnetic attraction, it will naturally rotate open due to gravity, so that the friction disc can fall automatically.

[0023] Working principle: When needed, the material conveying track 5 is set at the end of the external conveyor belt. During feeding, the drive motor 803 is controlled by an external control structure to rotate the two pulleys 801, causing the rotating disk 702 to rotate. This causes the two connecting rod plates 703 to move synchronously. When the hinge point between the connecting rod plate 703 and the rotating disk 702 is in the lower half, the groove of the material conveying clamp 6 contacts the multiple friction discs below, which can drive the material conveying clamp 6 to move and push the material. When the friction disc at the end pushes the material to the clamping position... The hinge point between the connecting rod plate 703 and the rotating disk 702 is located in the upper part, which can pull the material conveying plate 6 up and reset, facilitating continuous material feeding. The two clamping parts 2 are close to each other and clamp the friction disk in a pointed cone shape. The clamping parts 2 drive the friction disk to rotate. Combined with the operation of the grinding disk 3 and the grinding motor 4, grinding can be performed. After grinding is completed, the power supply of the electromagnet is disconnected, so that the curved plate 9 can be naturally rotated open, and the friction disk can fall naturally to achieve material feeding. By repeating the above, continuous material feeding can be performed.

[0024] It should be noted that since two parallel connecting plates 703 are used and the hinge points are at the same corresponding position, the four hinge points form a parallelogram. Combined with the regular movement of the two points above the rotating disk 702, the two points below can move back and forth stably.

[0025] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. 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.
