Description

Technical Field

[0001] This utility model relates to the field of machining technology, and specifically to a mandrel lathe material pulling mechanism. Background Technology

[0002] In the field of machining, during the lathe machining of mandrel-type workpieces (such as drive shafts and positioning shafts), the chuck and ejector pins are used to achieve positioning at both ends to ensure cutting accuracy. After machining, the mandrel removal from the chuck is a crucial step connecting machining and subsequent processes; its efficiency and stability directly affect the overall production rhythm and mandrel quality. Currently, there are still many technical challenges in the mandrel removal operation after machining in the industry, specifically as follows: Manual material removal is inefficient and poses high safety risks: After machining on a traditional lathe, the mandrel is often manually pulled out of the chuck. This is not only labor-intensive, but also requires operators to be in close contact with the hot mandrel and rotating parts of the lathe, which can easily lead to burns or entanglement accidents. At the same time, it cannot meet the design requirements of an automated workshop. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0013] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0014] The following is a description of the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.

[0015] Example 1 A mandrel lathe material removal mechanism, comprising: The slide table 1 is slidably mounted on the lathe and slides through a drive mechanism. A center pin 11 is provided on the side of the slide table 1 facing the chuck seat. The material extraction module 2 includes a mounting assembly 21 mounted on the slide table 1 and a material extraction assembly 22 mounted on the mounting assembly 21. The mounting assembly 21 includes a mounting base 211 fixed to the slide table 1 by bolts and an L-shaped bracket 212 connected to the mounting base 211. The material extraction assembly 22 includes a translation cylinder 221 horizontally arranged along the sliding direction of the slide table 1, a lifting cylinder 222 vertically connected to the end of the piston rod of the translation cylinder 221, and a gripping cylinder 223 disposed at the end of the piston rod of the lifting cylinder 222. The movable end of the gripping cylinder 223 is provided with two symmetrically distributed grippers 2231.

[0016] like Figures 1-4 As shown, the working principle of this utility model is as follows: First, the drive mechanism drives the slide table 1 to slide along the linear guide towards the spindle, so that the ejector pin 11 on the slide table 1 precisely abuts against one end of the spindle, and the other end enters the lathe chuck and is fixed by the chuck, forming a two-end positioning to ensure that the spindle does not wobble during the machining process. After the positioning is completed, the lathe starts to cut the spindle. Secondly, after the mandrel is processed, the material extraction module 2 starts to operate. The translation cylinder 221 drives the lifting cylinder 222 and the gripping cylinder 223 to move horizontally until the gripper 2231 is aligned with the top of the mandrel. Then the piston rod of the lifting cylinder 222 extends, driving the gripping cylinder 223 to move downward, so that the gripper 2231 is close to the mandrel. After it is in place, the gripping cylinder 223 drives the two grippers 2231 to close, and clamps the mandrel through the inner V-shaped clamping block 22311. Finally, after the jaws clamp the mandrel, the lathe chuck is unlocked, and the drive mechanism drives the slide 1 to move away from the chuck along the linear guide rail. Simultaneously, the clamped mandrel is smoothly pulled out of the chuck. After the slide 1 moves to the preset hoisting position, the external transfer mechanism grabs the mandrel and transfers it to the next process, completing the automatic transfer. After that, each cylinder is reset, and the above process is repeated after the next mandrel is processed.

[0017] This utility model achieves automatic positioning, clamping, extraction and transfer of the mandrel after processing through the coordinated action of the slide table 1, translation cylinder 221, lifting cylinder 222 and gripping cylinder 223. The entire process does not require manual material handling, avoiding the safety risks of manual contact with rotating parts, while reducing the dependence on operator skills and adapting to the cycle time of automated production lines.

[0018] As a further preferred embodiment, the inner sides of the two sets of grippers 2231 are provided with clamping blocks 22311 adapted to the mandrel, and the cross section of the clamping blocks 22311 is V-shaped.

[0019] Specifically, the V-shaped clamping block 22311 on the inner side of the gripper 2231 is adapted to the outer circle of the mandrel. The three-point positioning is formed by the inclined surfaces on both sides, which can automatically correct the slight deviation of the mandrel. At the same time, the contact area is increased, making the clamping force more uniform and preventing the mandrel from slipping during extraction and transfer.

[0020] As a further preferred embodiment, the surface of the clamping block 22311 is provided with anti-slip texture.

[0021] Specifically, the anti-slip texture on the surface of the clamping block 22311 can increase the friction with the mandrel, further preventing the mandrel from slipping during clamping, while avoiding indentations or scratches on the mandrel surface caused by rigid clamping, thus protecting the precision of the machined mandrel.

[0022] As a further preferred embodiment, the mounting base 211 is connected to the upper end of the slide table 1 by bolts and an adjusting shim is provided between the two, the adjusting shim being used to adjust the installation height of the mounting assembly 21.

[0023] Specifically, the adjusting shims between the mounting base 211 and the slide table 1 can finely adjust the height of the mounting component 21, so that the material pulling component 22 can be precisely aligned with mandrels of different diameters and specifications. It can be adapted to various lathes or mandrel models without changing the overall structure, reducing equipment modification costs and shortening debugging time.

[0024] As a further preferred embodiment, the bottom of the slide table 1 is provided with a linear guide rail, the slide table 1 is slidably engaged with the guide rail seat of the lathe through the linear guide rail, and the slide table 1 is connected to the transmission end of the drive mechanism.

[0025] Specifically, the slide table 1 cooperates with the lathe guide rail seat through the bottom linear guide rail, which has low sliding resistance and precise guidance, ensuring the coaxiality of the ejector pin 11 when it is positioned, and the mandrel is pulled out smoothly along a straight line when the material is pulled out, reducing the deformation of the mandrel or the wear of the chuck caused by the slide table shaking, and extending the service life of the equipment.

[0026] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
