A device hole is laterally opened through the top of one side surface of the connecting seat. A rotating cylinder arranged along its length is laterally slidably connected inside the device hole. A top column is slidably connected inside the rotating cylinder along its length. A hydraulic rod is laterally fixedly connected to the other end of the upper surface of the movable seat through a mounting bracket. A connecting disc coaxial with the piston rod of the hydraulic rod is rotatably connected to the outer end of the piston rod. The other end of the connecting disc is fixedly connected to one end surface of the top column.

[0009] Preferably, the inner surface of the rotating cylinder is fixedly connected with a plurality of limiting protrusions along its length, and the outer surface of the top column is provided with a plurality of limiting grooves that correspond to and are adapted to the plurality of limiting protrusions.

[0010] Preferably, the outer diameters of the piston rod of the hydraulic rod and the connecting disc are both smaller than the inner diameter of the rotating cylinder.

[0011] Preferably, a three-jaw chuck is provided on the other side of the front part of the bed of the main body of the equipment, and the central axis of the three-jaw chuck and the rotating cylinder are located on the same straight line.

[0012] Preferably, a turret assembly is provided at the rear of the bed of the main body of the device.

[0013] Preferably, the central axes of the hydraulic rod, the connecting plate, the top column, and the rotating cylinder are located on the same straight line.

[0014] This utility model, by setting a tail-top mechanism, in addition to being driven to move laterally by the movable seat at the bottom, also has a rotating cylinder and a top column inside. The top column can move laterally inside the rotating cylinder. The workpiece is clamped and fixed by the top column and the three-jaw chuck.

[0019] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0020] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0021] Reference Figure 1-3 An embodiment of the present invention is proposed, a turret tail top, comprising a device body 1 and a tail top mechanism 3;

[0022] A movable seat 2 that slides along its length is provided on one side of the upper front surface of the bed of the main body 1 of the equipment, and the tail top mechanism 3 is provided on the upper surface of the movable seat 2.

[0023] The tail-top mechanism 3 includes a connecting seat 31 fixedly connected to one end of the upper surface of the movable seat 2. A device hole 32 is laterally opened through the top of one side surface of the connecting seat 31. A rotating cylinder 33 is laterally slidably connected inside the device hole 32 along its length direction. A top column 35 is slidably connected inside the rotating cylinder 33 along its length direction. A hydraulic rod 37 is laterally fixedly connected to the other end of the upper surface of the movable seat 2 through a mounting bracket. A connecting disc 36 coaxial with the piston rod of the hydraulic rod 37 is rotatably connected to the outer end of the piston rod of the hydraulic rod 37. The other end of the connecting disc 36 is fixedly connected to one end surface of the top column 35.

[0024] A three-jaw chuck 5 is provided on the other side of the front of the bed of the main body 1. The central axes of the three-jaw chuck 5 and the rotating cylinder 33 are on the same straight line.

[0025] The back of the bed of the main body 1 is equipped with a turret assembly 4.

[0026] The device clamps the workpiece using the tail-top mechanism 3 and the three-jaw chuck 5. After clamping, the three-jaw chuck 5 rotates under the drive of the drive structure, which can drive the workpiece to rotate synchronously. During the rotation of the workpiece, the turret assembly 4 can perform cutting operations on the workpiece. The turret assembly 4 and the three-jaw chuck 5 are existing structures of turret tail-top machines and are mature existing technologies, so they will not be described in detail here.

[0027] In actual use, the tail-end mechanism 3 can be driven to move laterally synchronously through the movable seat 2 at its bottom end, changing the distance between one end of it and the three-jaw chuck 5, thereby clamping and positioning the shaft-shaped workpiece. It is also equipped with a laterally sliding top column 35. By driving the top column 35 to move laterally through the hydraulic rod 37, the clamping range of the device can be further expanded, which can clamp and fix shorter or longer workpieces, thus improving the practicality of the device.

[0028] The movable seat 2 is equipped with a mating structure for the hydraulic rod 37, which can control the extension and retraction of the hydraulic rod 37.

[0029] Furthermore, the inner surface of the rotating cylinder 34 is fixedly connected with a plurality of limiting protrusions 34 along its length direction, and the outer surface of the top column 35 is provided with a plurality of limiting grooves corresponding to and adapted to the plurality of limiting protrusions 34 along its length direction.

[0030] The limiting protrusion 34 serves as a limit, ensuring that the top column 35 can only move along the length of the rotating cylinder 34 and cannot rotate on its own.

[0031] Furthermore, the outer diameters of the piston rod of the hydraulic rod 37 and the connecting disc 36 are both smaller than the inner diameter of the rotating cylinder 33.

[0032] The central axes of the hydraulic rod 37, connecting plate 36, top column 35 and rotating cylinder 33 are located on the same straight line.

[0033] The outer diameters of the piston rod of the hydraulic rod 37 and the connecting plate 36 are both smaller than the inner diameter of the rotating cylinder 33, which can prevent friction from occurring when the piston rod of the hydraulic rod 37 extends into the interior of the rotating cylinder 33. The central axes of the hydraulic rod 37, the connecting plate 36, the top column 35 and the rotating cylinder 33 are located on the same straight line, which can ensure that the rotation axis of the workpiece is horizontal when it is driven to rotate, and there will be no instability problem.

[0034] During operation, the tail-end mechanism 3 can be driven to move laterally synchronously through the movable seat 2 at its bottom end, changing the distance between one end and the three-jaw chuck 5, thereby clamping and positioning the shaft-shaped workpiece. It is also equipped with a laterally sliding top column 35. By driving the top column 35 to move laterally through the hydraulic rod 37, the clamping range of the device can be further expanded, which can clamp and fix shorter or longer workpieces, thus improving the practicality of the device.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
