Description
Technical Field
[0001] This utility model relates to the field of tail shaft machining technology for machine tools, specifically a tail shaft forming machine for machine tools. Background Technology
[0002] The tailstock of a machine tool is a key component of the tailstock assembly. It is usually a slender cylindrical structure that can move axially and perform certain positioning operations. Its main function is to cooperate with the machine tool spindle to support long workpieces and ensure their stability during machining. Especially when performing machining operations such as turning, when the length of the workpiece exceeds the range that the chuck can stably support, the center mounted on the tailstock will press against the other end of the workpiece to prevent bending deformation, vibration, etc. under the action of cutting forces and other external forces, thereby ensuring machining accuracy.
[0003] In some existing machine tool tail shaft forming machines, the tail shaft blank is fixed by applying pressure with an external pneumatic cylinder when processing the tail shaft of the machine tool;
[0004] Existing tail shaft forming machines for some machine tools have the following problems: during the machining of the tail shaft of the machine tool, the pneumatic cylinder is prone to air leakage during the clamping process, which can easily cause the tail shaft blank to loosen. When the tail shaft blank rotates at high speed, it can easily fly out, causing injury to workers. To address this, we propose a tail shaft forming machine for machine tools. Utility Model Content

When processing the tail shaft of a machine tool, it is convenient to fix the tail shaft blank of the machine tool, and it is not easy for the tail shaft blank of the machine tool to loosen. This avoids the tail shaft blank of the machine tool flying out and causing injury to the workers, and can effectively solve the problems in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a tail shaft forming machine for a machine tool, including a machine base, a strip block provided in the middle of the rear side of the upper end of the machine base, a slide bar slidably connected inside the strip block, a support rod slidably connected inside the slide bar, a turning tool fixedly connected to the front end of the support rod, and a clamping mechanism.

When machining the tailstock of the machine tool, it is convenient to fix the tailstock blank of the machine tool, and it is not easy for the tailstock blank of the machine tool to loosen, thus avoiding the tailstock blank of the machine tool from flying out and causing injury to the workers.
[0008] Furthermore, the machine tool is equipped with a control switch group on its exterior. The input end of the control switch group is electrically connected to the output end of an external power supply to provide electrical connections for various electrical appliances.
[0009] Furthermore, the clamping mechanism also includes a worm and a worm wheel. The worm wheel is fixedly sleeved on the lower outer side of the rotating shaft. The worm is rotatably connected between the front and rear inner walls of the turntable. The worm and the worm wheel are meshed and connected to provide a rotatable connection.
[0010] Furthermore, the clamping mechanism also includes an adjusting block and an adjusting wheel. The adjusting block is fixedly connected to the front end of the worm gear, and the adjusting wheel is provided on the outside of the turntable. The adjusting block and the adjusting wheel are installed together for easy fixation.
[0011] Furthermore, the clamping mechanism also includes a motor, which is mounted on the top wall of the machine base. The upper end of the output shaft of the motor is fixedly connected to the lower middle part of the turntable, and the input end of the motor is electrically connected to the output end of the control switch group to provide rotation drive.

The input end of the motor is electrically connected to the output end of the control switch group to provide movement drive.
[0013] Furthermore, the slider is internally rotatably connected to a second lead screw, and the threaded hole at the rear end of the support rod is threadedly connected to the second lead screw. The upper end of the slider is equipped with a third motor, and the lower end of the output shaft of the third motor is threadedly connected to the upper end of the second lead screw. The input end of the third motor is electrically connected to the output end of the control switch group to provide movement drive.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The tail shaft forming machine of this machine tool has the following advantages:
[0015] By rotating the adjustment wheel, the adjustment wheel drives the rotating shaft to rotate through the adjustment block, worm gear, and meshing worm wheel. The rotating shaft, through the adapter plate, causes the rotating column to rotate and slide inside the arc groove, which in turn drives the cross slide bar to move towards the center inside the cross slide groove. This, in turn, causes the clamping block to move towards the center to hold the tail shaft workpiece. When machining the tail shaft of the machine tool, it is convenient to fix the tail shaft workpiece, and it is less likely to loosen the tail shaft workpiece, thus preventing the tail shaft workpiece from flying out and causing injury to the workers.

Then the motor 8 is operated, and the output shaft of the motor 8 drives the lead screw 7 to rotate. The rotation of the lead screw 7 will drive the support rod 9 of the screw to move up and down, and then drive the turning tool 10 to move up and down to turn the tail shaft to process the blank.

The input end of the motor 201 is electrically connected to the output end of the control switch group 11. When machining the tailstock of the machine tool, the tailstock workpiece is placed between the clamping blocks 205. Then, the adjusting wheel 212 is inserted into the adjusting block 211. Then, by rotating the adjusting wheel 212, the adjusting wheel 212 will adjust the position of the machine tool. The segment 211 drives the worm 209 to rotate. The rotation of the worm 209 drives the rotating shaft 206 to rotate through the meshing worm wheel 210. The rotation of the rotating shaft 206 drives the adapter plate 207 to rotate. The rotation of the adapter plate 207 drives the rotating column 213 to rotate and slide inside the arc groove 208, which in turn drives the cross slide bar 204 to move towards the center inside the cross slide groove 203.

The rotation of the worm 209 drives the rotating shaft 206 to rotate through the meshing worm wheel 210. The rotation of the rotating shaft 206 drives the adapter plate 207 to rotate. The rotation of the adapter plate 207 causes the rotating column 213 to rotate and slide inside the arc groove 208, which in turn drives the cross slide bar 204 to move towards the center inside the cross slide groove 203, thereby driving the clamping blocks 205. The workpiece is held closer to the center. Then, the control switch group 11 controls the operation of motor 201.

While the workpiece is rotating, the control switch group 11 controls the operation of motor 4. The output shaft of motor 4 drives the lead screw 5 to rotate. The rotation of lead screw 5 causes the threaded slide bar 6 to move forward inside the strip block 3, so that the turning tool 10 contacts the workpiece. Then, motor 8 operates. The output shaft of motor 8 drives the lead screw 7 to rotate. The rotation of lead screw 7 causes the screw support rod 9 to move up and down, thereby causing the turning tool 10 to move up and down, turning the workpiece.
