Description

Technical Field

[0001] This utility model relates to the field of positioning tooling technology, and more specifically to a lathe axial length positioning tooling. Background Technology

[0002] Axial length refers to the dimension along the axis or length direction. In mechanical engineering, axial length is an important parameter that directly affects the design and manufacture of mechanical parts.

[0003] When cutting and chamfering bar stock, axial positioning of the bar stock is required. Currently, chucks are generally used to assist in the positioning operation. However, the positioning, cutting and chamfering steps of the bar stock are currently independent of each other, and the integration and automation of the entire processing process are insufficient, which affects work efficiency. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a lathe axial length positioning fixture to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a lathe axial length positioning fixture, including a conveying mechanism, a cutting mechanism, a positioning mechanism and a chamfering mechanism. The conveying mechanism is used to convey the bar to the positioning mechanism and assist in unloading the chamfered bar. The cutting mechanism is used to cut the bar. The positioning mechanism is used to clamp and position the bar and pull the bar to the chamfering mechanism. The chamfering mechanism is used to chamfer the bar.

[0006] Preferably, the conveying mechanism includes a mounting frame and a guide block. A conveying roller is mounted on the mounting frame, an extension frame is fixedly connected to one side of the mounting frame, and a guide rod is fixedly connected to the extension frame. Two guide rods are provided.

[0007] Preferably, a guide frame is fixedly connected to one side of the guide block, the guide frame is sleeved on the surface of the guide rod, the guide block is provided with a first inclined surface and a second inclined surface, and a compression spring is sleeved on the surface of the guide rod. One end of the compression spring is fixedly connected to the side of the guide frame away from the guide block, and the other end is fixedly connected to the side of the extension frame facing the guide frame.

[0008] Preferably, the cutting mechanism includes an electric telescopic rod, a blade holder, and a cutting blade. The output end of the electric telescopic rod is fixedly connected to the blade holder via a connecting rod. A motor is fixedly installed on one side of the blade holder, and a rotating shaft is rotatably installed on the blade holder. The cutting blade is fixedly installed on the surface of the rotating shaft. A first bevel gear is fixedly connected to the output end of the motor, and a second bevel gear is fixedly connected to one end of the rotating shaft. The first bevel gear and the second bevel gear are meshed together.

[0009] Preferably, the positioning mechanism includes a receiving frame, a moving seat, and a second motor. Threaded rods are rotatably mounted on the receiving frame, and two threaded rods are symmetrically arranged. The moving seat is threaded onto the surface of the threaded rods, and an electric chuck is fixedly mounted on the top of the moving seat.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] The conveyor roller pulls the bar through the electric chuck, which then clamps and positions the bar. After the cutting blade cuts the bar, the electric chuck and the cut bar move together between two chamfering machines. The chamfering machines chamfer both ends of the cut bar. After chamfering, the electric chuck moves back to its initial position and slightly loosens its grip on the cut bar. During this process, the cut bar automatically falls onto the ejector plate and is output. This invention adopts an assembly line processing method, which can automatically complete the conveying and positioning of the bar, ensuring the stability of the bar. In addition, the cutting, chamfering and ejection of the bar are automatically completed during the positioning process. The whole process is highly automated and integrated, improving work efficiency. Attached Figure Description

The lathe axial length positioning fixture involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] This utility model provides a lathe axial length positioning fixture, including a conveying mechanism 1, a cutting mechanism 2, a positioning mechanism 3, and a chamfering mechanism 4. The conveying mechanism 1 is used to convey the bar to the positioning mechanism 3 and assist in unloading the chamfered bar. The cutting mechanism 2 is used to cut the bar.

[0022] Furthermore, the conveying mechanism 1 includes a mounting frame 11 and a guide block 15. A conveying roller 12 is mounted on the mounting frame 11. An extension frame 13 is fixedly connected to one side of the mounting frame 11. A guide rod 14 is fixedly connected to the extension frame 13. There are two guide rods 14. A guide frame 16 is fixedly connected to one side of the guide block 15. The guide frame 16 is sleeved on the surface of the guide rod 14. The guide frame 16 and the guide rod 14 form a sliding guide fit along the axis of the guide rod 14. A first inclined surface 151 and a second inclined surface 152 are provided on the guide block 15. A compression spring 17 is sleeved on the surface of the guide rod 14. One end of the compression spring 17 is fixedly connected to the side of the guide frame 16 away from the guide block 15, and the other end is fixedly connected to the side of the extension frame 13 facing the guide frame 16. The elastic force of the compression spring 17 can drive the guide frame 16 to move in the direction away from the extension frame 13.

[0023] Furthermore, the cutting mechanism 2 includes an electric telescopic rod 21, a blade holder 22, and a cutting blade 25. The output end of the electric telescopic rod 21 is fixedly connected to the blade holder 22 via a connecting rod 23. A motor 24 is fixedly installed on one side of the blade holder 22, and a rotating shaft 26 is rotatably installed on the blade holder 22. The cutting blade 25 is fixedly installed on the surface of the rotating shaft 26. A first bevel gear is fixedly connected to the output end of the motor 24, and a second bevel gear is fixedly connected to one end of the rotating shaft 26. The first bevel gear and the second bevel gear mesh with each other, and the first bevel gear and the second bevel gear cooperate with each other to convert the output power of the motor 24 into the rotational force of the rotating shaft 26.

[0024] Furthermore, the positioning mechanism 3 includes a receiving frame 31, a motion seat 32, and a second motor 36. A threaded rod 34 that can rotate around its own axis is rotatably mounted on the receiving frame 31. Two threaded rods 34 are symmetrically arranged. The motion seat 32 is threadedly mounted on the surface of the threaded rod 34. An electric chuck 33 is fixedly mounted on the top of the motion seat 32. The second motor 36 is fixedly mounted on the surface of the receiving frame 31. The output end of the second motor 36 is fixedly connected to one end of one of the threaded rods 34. A power transmission component 37 is provided between the two threaded rods 34 to realize the power transmission between them. Preferably, the power transmission component 37 is a belt drive structure. An inclined ejector plate 35 is fixedly mounted on one side of the receiving frame 31. The ejector plate 35 is used to guide the cut and chamfered bar material outward.

[0025] Furthermore, the chamfering mechanism 4 includes a chamfering machine 41, and two chamfering machines 41 are provided. An electric slide rail 42 is installed at the bottom of the chamfering machine 41. The electric slide rail 42 is used to control the two chamfering machines 41 to move in a direction that is closer to each other or away from each other.

[0026] The working principle of this utility model is as follows: The conveying roller 12 conveys the bar and pulls it through the electric chuck 33. Then the conveying roller 12 stops conveying, and the three jaws of the electric chuck 33 move towards each other to clamp and position the bar. At this time, the motor 24 drives the rotating shaft 26 to rotate around its own axis through the first bevel gear and the second bevel gear. The rotating shaft 26 rotates and drives the cutting blade 25 to rotate synchronously around the axis of the rotating shaft 26. The output end of the electric telescopic rod 21 shortens and pulls the cutting blade 25 to move downward. When the cutting blade 25 cuts the bar, the output end of the electric telescopic rod 21 extends upward and controls the cutting blade 25 to return to the initial position. The motor 24 stops running.

[0027] Then, motor 36 drives one threaded rod 34 to rotate around its own axis. The rotation of one threaded rod 34 drives another threaded rod 34 to rotate synchronously around its own axis through power transmission component 37. While the threaded rod 34 rotates, it drives the motion seat 32 and the electric chuck 33 to move synchronously along the axis of the threaded rod 34. The cut bar moves synchronously under the traction of the electric chuck 33. During this process, one end of the cut bar slides along the first inclined surface 151 and squeezes the guide block 15, causing the guide frame 16 to slide along the guide rod 14 towards the extension frame 13. The compression spring 17 is in the guide frame 1 Under the compression of 6, the spring shrinks and the elasticity increases. When one end of the cut bar leaves the first inclined plane 151 and moves to the second inclined plane 152, the elasticity of the compression spring 17 is gradually released and drives the guide block 15 back to the initial position. When the cut bar moves between the two chamfering machines 41, the motor 2 36 stops running, and the cut bar remains stationary. The electric slide rail 42 pulls the two chamfering machines 41 to move towards each other. The chamfering machine 41 chamfers both ends of the cut bar. After the chamfering is completed, the electric slide rail 42 pulls the two chamfering machines 41 to move away from each other and return to the initial position.

[0028] Motor 36 then reverses its rotation. Similarly, electric chuck 33 moves in the opposite direction along the axis of threaded rod 34. At this time, electric chuck 33 slightly loosens its grip on the cut bar. One end of the cut bar slides along the second inclined plane 152. Under the obstruction of the second inclined plane 152, the center of gravity of the cut bar gradually shifts to the top of the ejector plate 35. Under its own gravity, it falls onto the ejector plate 35 and is output outward. When electric chuck 33 returns to its initial position, conveying roller 12 conveys the bar again, and so on.
