Description

Technical Field

[0001] The utility model relates to the technical field of thread rolling, in particular to a thread rolling device for micro-shaft processing. Background Technique

[0002] A thread rolling machine is a multi-functional cold extrusion forming machine tool. The thread rolling machine can perform thread rolling, straight thread rolling, and helical thread rolling on workpieces in a cold state within its rolling pressure range, as well as rolling of straight teeth, helical teeth, and helical spline gears, straightening, necking, rolling, and various forming rolling. The working principle of the thread rolling machine is mainly based on the rolling technology. During the processing, the device extrudes the workpiece through the rollers, causing plastic deformation on the surface of the workpiece, thereby forming the required thread shape. Compared with the traditional cutting processing method, rolling processing does not require removing a large amount of material, so it can save raw materials and reduce heat generation during the processing. This processing method has the advantages of high precision, high efficiency, and low energy consumption, and is especially suitable for micro-shaft parts with high requirements for thread processing quality. However, metal debris is inevitably generated during the thread rolling process. The debris remaining on the rollers will interfere with the thread rolling process, affecting the quality of thread rolling, and the debris is not easy to clean. Therefore, we propose a thread rolling device for micro-shaft processing. Content of the Utility Model

[0003] The purpose of the utility model is to provide a thread rolling device for micro-shaft processing, so as to solve the problems of debris interference during thread rolling and difficult cleaning of debris proposed in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A thread rolling device for micro-shaft processing, including a machine body, two rollers are rotatably installed on the machine body, thread grooves are opened on the rollers, a workpiece table is installed between the rollers, the workpiece table is fixedly installed on the machine body, sliding plates are installed below both rollers, the sliding plates are fixedly installed on the machine body, chip discharge grooves are opened on both sides of the machine body, iron chip boxes are also provided on both sides of the machine body, and a chip removal mechanism is also installed on the machine body.

[0005] Among them, the chip discharge groove is located at the bottom end of the sliding plate.

[0006] Among them, the iron chip box is located below the chip discharge groove.

[0007] Among them, the chip removal mechanism includes a toothless gear, the toothless gear is fixedly installed on the front of the roller, baffles are respectively fixedly installed on both sides of the front of the machine body, a gear rod is rotatably installed on the baffles, a gear is fixedly installed on the gear rod, a rotating sleeve is fixedly installed on the baffle, the gear rod is located in the rotating sleeve, and the rotating sleeve and the gear rod are connected by a spring piece, the gear meshes with the toothless gear, and a brush is installed on the gear, and the brush can rotate following the gear.

[0008] Among them, the toothless gear rotates coaxially with the roller, and the number of teeth on the toothless gear is only half of the normal number.

[0009] Wherein, the baffle is fixedly connected to the sliding plate.

[0010] Wherein, the length of the brush is the same as that of the roller, and the bristles on the brush can just touch the inside of the thread groove.

[0011] The utility model has at least the following beneficial effects:

[0012] When the roller is performing rotary thread rolling, the toothless gear also rotates accordingly, and at the same time drives the gear to rotate, so that the brush on the gear can clean the iron filings in the thread groove. At this time, the spring piece between the gear rod and the rotating sleeve is tightened. When the side without teeth of the toothless gear rotates over, the gear disengages from the toothless gear, and the gear loses the power source. The spring piece gradually relaxes, causing the gear to rotate back again, and the brush can clean the thread groove again. Under the continuous rotation of the roller, the toothless gear also rotates continuously, enabling the above process to be repeated. The brush can repeatedly clean the iron filings in the thread groove, and at the same time, the iron filings are brushed onto the sliding plate and finally discharged into the iron filings box through the chip discharge groove, which is convenient and clean during use.

Detailed Embodiment

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1

[0022] Please refer to Figures 1 to 5 , the present invention provides a technical solution: a thread rolling device for microshaft processing, including a machine body 1. Two rollers 2 are rotatably installed on the machine body 1. Thread grooves 20 are provided on the rollers 2. A workpiece table 3 is installed between the rollers 2. The workpiece table 3 is fixedly installed on the machine body 1. When the device starts the thread rolling work, the workpiece is placed on the workpiece table 3, and the rollers 2 rotate to squeeze the workpiece, causing plastic deformation on the surface of the workpiece, so as to form the required thread shape. Below both of the two rollers 2, there are slide plates 4 fixedly installed on the machine body 1. Chip discharge grooves 5 are provided on both sides of the machine body 1. The chip discharge grooves 5 are located at the bottom end of the slide plates 4. Iron chip boxes 6 are also provided on both sides of the machine body 1. The iron chip boxes 6 are located below the chip discharge grooves 5. A chip removal mechanism 7 is also installed on the machine body 1.

[0023] The chip removal mechanism 7 includes a toothless gear 70 fixedly installed on the front of the roller 2. The toothless gear 70 rotates coaxially with the roller 2. The number of teeth on the toothless gear 70 is only half of the normal number. On both sides of the front of the machine body 1, there are baffle plates 71 fixedly installed respectively. The baffle plates 71 are fixedly connected to the slide plates 4. A gear rod 72 is rotatably installed on the baffle plates 71. A gear 73 is fixedly installed on the gear rod 72. A rotating sleeve 74 is fixedly installed on the baffle plates 71. The gear rod 72 is located inside the rotating sleeve 74. The rotating sleeve 74 and the gear rod 72 are connected by a spring piece 75. The gear 73 meshes with the toothless gear 70. A brush 76 is installed on the gear 73. The length of the brush 76 is the same as that of the roller 2. The bristles on the brush 76 can just touch the inside of the thread groove 20. The brush 76 can rotate following the gear 73. While the roller 2 rotates, the toothless gear 70 also rotates, and at the same time drives the gear 73 to rotate, so that the brush 76 on the gear 73 can clean the iron chips in the thread groove 20. At this time, the spring piece 75 between the gear rod 72 and the rotating sleeve 74 is tightened. When the side without teeth of the toothless gear 70 rotates over, the gear 73 disengages from the toothless gear 70, and the gear 73 loses the power source. The spring piece 75 gradually relaxes, causing the gear 73 to rotate back again, and the brush 76 can clean the thread groove 20 again. Under the continuous rotation of the roller 2, the toothless gear 70 also rotates continuously, and the rotation direction of the gear 73 is constantly switched, so that the brush 76 repeatedly cleans the roller 2, thereby achieving the effect of removing the iron chips in the thread groove 20.

[0024] Embodiment 2

[0025] As Figure 6 , in Embodiment 2, other structures remain unchanged. Different from Embodiment 1, the length of the slide plate 4 is extended so that the slide plate 4 can be connected to the workpiece table 3 to prevent the iron filings in the threaded groove 20 from naturally falling off onto the machine body 1.
