Description

Technical Field

[0001] The utility model relates to the technical field of sprocket production, in particular to a lathe for sprocket production and processing. Background Technique

[0002] A sprocket is a wheel with a hollow center and tooth-like chain engaging teeth on the edge. When producing sprockets on a lathe, in order to avoid the three-jaw chuck affecting the processing of the surface of the sprocket substrate during clamping and fixing, it is common to first clamp the edge of the sprocket substrate, then pre-drill a hole in the middle, then remove it, and then clamp and position its center and process the edge to complete the processing of a sprocket. Such a sprocket processing method is too cumbersome. After the sprocket is processed, tooth heat treatment and quenching are still required. However, the existing processing lathes need to remove the formed sprocket and use a quenching device for quenching, which is relatively cumbersome. Workers need to continuously remove the produced sprockets and place them in the quenching device, which is not efficient and convenient, and increases the labor intensity of workers. Therefore, we propose a lathe for sprocket production and processing to solve the above problems. Content of the Utility Model

[0003] The purpose of the utility model is to provide a lathe for sprocket production and processing, so as to solve the problem that after the sprocket is processed, tooth heat treatment and quenching are still required, but the existing processing lathes need to remove the formed sprocket and use a quenching device for quenching, which is relatively cumbersome, and workers need to continuously remove the produced sprockets and place them in the quenching device as mentioned in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A lathe for sprocket production and processing, including a lathe,

[0005] A driving component is fixedly installed inside the lathe. A guide rail is fixedly installed inside the upper end of the lathe. A laser cutting head is arranged on the guide rail. A fixed sleeve is arranged on the right side of the lathe. A screw knob is rotatably installed at the left end of the fixed sleeve. A first screw rod is inserted into the screw knob through a thread. The right end of the first screw rod is inserted into the fixed sleeve. A quenching component is arranged at the left end of the first screw rod. The quenching component includes a first arc-shaped plate. The first arc-shaped plate is fixedly installed on the left side of the first screw rod. A second screw rod is rotatably installed at the left end of the first screw rod. A second arc-shaped plate is sleeved on the upper end of the second screw rod through a thread. A sealing package is fixedly installed on the lower right side of the second arc-shaped plate. The lower end of the sealing package is inserted into the first arc-shaped plate. Heating coils are installed inside the rear ends of the first arc-shaped plate and the second arc-shaped plate. The two groups of heating coils are arranged up and down opposite to each other. A water pipe is installed on the right side of the lathe. Nozzles are fixedly installed at the front ends of the first arc-shaped plate and the second arc-shaped plate respectively. The two groups of nozzles are fixedly connected to the water pipe.

[0006] Preferably, both groups of the spray heads are arranged in an inclined shape, and the upper and lower opposite ends of the two groups of spray heads are inclined forward.

[0007] Preferably, a first partition board is fixedly installed inside the lathe, and the first partition board is located at the middle part of the lathe.

[0008] Preferably, second partition boards are rotatably installed inside both the first arc-shaped plate and the second arc-shaped plate. Torque springs are arranged at the joints of the two groups of second partition boards and the first arc-shaped plate and the second arc-shaped plate. One end where the two groups of second partition boards are in contact is inclined forward.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: The raw material fixed at the upper end of the driving component is cut into a sprocket shape by the laser cutting head of the present utility model, so that the motor in the driving component drives the raw material to rotate, and the formed tooth part of the raw material moves into the rear ends of the first arc-shaped plate and the second arc-shaped plate. The heating coils at the rear ends of the first arc-shaped plate and the second arc-shaped plate perform heat treatment on the formed teeth on the sprocket. It can perform heat treatment on the teeth of the sprocket while cutting the raw material into a sprocket. And because the high temperature generated by the laser cutting head for cutting the raw material has not been completely removed, the two groups of heating coils can heat up and quench the teeth on the sprocket in the shortest time, improving the production efficiency of the sprocket. After heat treatment, the teeth of the sprocket enter the front ends of the first arc-shaped plate and the second arc-shaped plate, and the cooling water sprayed by the water pipe and the two groups of spray heads sprays on the teeth of the sprocket to cool the heat-treated formed sprocket synchronously.

Specific embodiments

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-5 , an embodiment provided by the present utility model: A lathe for sprocket production and processing, including a lathe 1,

[0019] A driving component 2 is fixedly installed inside a lathe 1. A guide rail 3 is fixedly installed inside the upper end of the lathe 1. A laser cutting head 4 is arranged on the guide rail 3. A fixed sleeve 6 is arranged on the right side of the lathe 1. A screw knob 7 is rotatably installed at the left end of the fixed sleeve 6. A first screw rod 8 is inserted into the screw knob 7 through threads. The right end of the first screw rod 8 is inserted into the fixed sleeve 6. A quenching component is arranged at the left end of the first screw rod 8. The quenching component includes a first arc-shaped plate 9. The first arc-shaped plate 9 is fixedly installed on the left side of the first screw rod 8. A second screw rod 10 is rotatably installed at the left end of the first screw rod 8. A second arc-shaped plate 11 is sleeved on the upper end of the second screw rod 10 through threads. A sealing package 12 is fixedly installed on the lower side of the right end of the second arc-shaped plate 11. The lower end of the sealing package 12 is inserted into the first arc-shaped plate 9. Heating coils 13 are installed inside the rear ends of the first arc-shaped plate 9 and the second arc-shaped plate 11. The two groups of heating coils 13 are arranged opposite to each other up and down. A water pipe 14 is installed at the right end of the lathe 1. Nozzles 15 are fixedly installed at the front ends of both the first arc-shaped plate 9 and the second arc-shaped plate 11. The two groups of nozzles 15 are fixedly connected to the water pipe 14. By rotating the screw knob 7, the first screw rod 8 and the quenching component are driven to approach the raw material fixed on the driving component 2. Then, by rotating the second screw rod 10, the second arc-shaped plate 11 is driven to approach the first arc-shaped plate 9, so that the distance between the first arc-shaped plate 9 and the second arc-shaped plate 11 is adapted to sprockets of different thicknesses. Heat treatment is performed on the sprocket through the heating coils 13 at the rear ends of the first arc-shaped plate 9 and the second arc-shaped plate 11. When the two groups of heating coils 13 perform heat treatment on the sprocket teeth, due to the high temperature generated during the cutting of the sprocket raw material by the laser cutting head 4, the two groups of heating coils 13 can quickly heat the sprocket teeth, enabling the laser cutting head 4 to quench the teeth formed by cutting the raw material, improving the production efficiency of the sprocket. Then, through the water pipe 14 and the two groups of nozzles 15, the cooling water from the outside is sprayed onto the sprocket teeth after heat treatment, so as to achieve synchronous cooling of the sprocket teeth after heat treatment, facilitating the worker to remove the sprocket from the upper end of the driving component 2.

[0020] Furthermore, both groups of nozzles 15 are arranged in an inclined shape. The upper and lower opposite ends of the two groups of nozzles 15 are inclined forward. According to the installation angles of the two groups of nozzles 15, the cooling water sprayed by the two groups of nozzles 15 can flow forward, avoiding the backward flow of the cooling water.

[0021] Furthermore, a first partition plate 5 is fixedly installed inside the lathe 1. The first partition plate 5 is located at the middle part of the lathe 1. This structure separates the residues generated by the cutting of the raw material and the cooling water through the first partition plate 5, preventing the residues and the cooling water from being mixed together.

[0022] Furthermore, a second partition plate 16 is rotatably installed inside each of the first arc plate 9 and the second arc plate 11. Torsion springs 17 are provided at the joints between the two groups of second partition plates 16 and the first arc plate 9 and the second arc plate 11. One end of the two groups of second partition plates 16 that are in contact with each other inclines forward. This structure separates the two groups of heating coils 13 and the two groups of nozzles 15 through the two groups of second partition plates 16 and the two groups of torsion springs 17, and can separate the cooling water sprayed by the two groups of nozzles 15 to prevent the cooling water from splashing onto the two groups of heating coils 13.

[0023] Working principle: When manufacturing a sprocket, as Figure 1 and Figure 2 shown, fix the raw material after punching on the driving component 2. The motor inside the lower end of the driving component 2 drives the workbench and the raw material at the upper end of the driving component 2 to rotate. While the raw material is rotating, the laser cutting head 4 moves on the guide rail 3. The laser cutting head 4 cuts the edge of the raw material into a toothed shape. The toothed part cut by the laser cutting head 4 enters the rear ends of the first arc plate 9 and the second arc plate 11 driven by the motor. As Figure 3 , Figure 4 and Figure 5 shown, rotate the second screw rod 10 to drive the second arc plate 11 and the seal package 12 to move up and down, so that the distance between the second arc plate 11 and the first arc plate 9 is adapted to the production thickness of the sprocket. The two groups of heating coils 13 at the rear ends of the first arc plate 9 and the second arc plate 11 heat the toothed part. And the toothed part has not completely cooled down after cutting. When the two groups of heating coils 13 perform heat treatment quenching on the toothed part, it can accelerate the heating speed. And the heat-treated toothed part moves to the front ends of the first arc plate 9 and the second arc plate 11. The cooling water sprayed through the water pipe 14 and the two groups of nozzles 15 cools the heat-treated toothed part, and then the steps of raw material production forming, heat treatment quenching and cooling can be completed, improving the production efficiency of the sprocket. The above is the entire working principle of the present utility model.

[0024] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model.
