Technical Field
[0001] The utility model relates to the technical field of tailstock anti-collision structures, in particular to a tailstock anti-collision structure for a numerically controlled lathe. Background Art
[0002] CNC lathe is one of the common CNC machine tools. It is mainly used for cutting inner and outer cylindrical surfaces of shaft parts or disk parts, inner and outer conical surfaces of arbitrary taper angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads. When CNC lathe is used for processing, the tailstock of the lathe needs to be used to clamp the workpiece. When in use, the lathe generally uses a chuck to clamp the workpiece to be processed, and then uses the tailstock ejector to support the other end of the workpiece to ensure that the workpiece does not shake during processing.
[0003] When using a CNC lathe to process shaft parts of different specifications, it is generally necessary to adjust the horizontal position of the entire tailstock. During the movement of the tailstock, if the operation is improper, the tailstock may collide with the tool holder and the machine body. At the same time, when the tool holder is moving, if the tool holder moves excessively, the tool holder may also collide with the tailstock. The above situations may cause damage to the tailstock. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a CNC lathe tailstock anti-collision structure which effectively buffers the collision of external forces, so that the external forces can avoid the collision with the tailstock to the maximum extent, thereby greatly improving the anti-collision effect of the tailstock.

One end of the plurality of buffer springs 8 is fixedly connected to an anti-collision piece 9. Two sliding grooves 10 are formed in the side wall of each anti-collision seat 7. Two sliding blocks 11 are slidably connected in the two sliding grooves 10. An elastic piece 12 is fixedly connected to the upper side wall of the two sliding blocks 11.

[0027] When in use, the electric slider 1 is installed on the electric slide rail of the lathe. When the tool rest collides with the anti-collision member 13, the elastic piece 12 and the anti-collision piece 9 in sequence, when the elastic piece 12 is hit, it can be stretched to the left and right as it is made of a soft and elastic material, playing a role in the first anti-collision. The setting of the anti-collision member 13 can buffer the remaining part of the collision for the second time, and then cooperate with the action of the buffer spring 8 to offset the external force three times, so that the external force is weakened to the greatest extent against the impact on the electric slider 1, greatly improving the anti-collision effect of the electric slider 1.
[0028] On the basis of Embodiment 1, the solution in Embodiment 1 is further refined and introduced in combination with the following specific working methods, as detailed in the following description.
