[0002] In the existing processing in our mine, workers often manually place the workpiece to be processed on the thread rolling machine for cutting, which causes personal safety of the operators. At the same time, manual operation requires operators to spend time and energy to place the workpiece in the correct position, which will reduce production efficiency and increase the processing cycle. Manual operation is easily affected by the operator's skill level and fatigue level, resulting in unstable processing quality, such as dimensional deviation or inconsistent surface roughness. Utility Model Content

[0003] The utility model aims to provide a thread rolling machine fixture to solve the problem that workers often manually place the workpiece to be processed on the thread rolling machine for cutting, which causes personal safety of the operator.

A slide groove is provided on the operating table along the axis in the horizontal direction. A lead screw is provided in the slide groove. One end of the lead screw passes through the operating table and is fixedly connected with an adjusting hand wheel. The other end of the lead screw contacts with the inner wall of the slide groove. A slider is connected to the lead screw. The first slide is fixedly connected to the slider. The first slide slides in a sliding manner in the slide groove.

[0006] The first slide is provided with an adjustment groove along the longitudinal axis, in which the second slide is slidably matched, a threaded through hole is provided on the second slide, a threaded rod is meshed in the threaded through hole, and one end of the threaded rod is connected to an adjustment hand wheel for driving the second slide to adjust longitudinally.

[0007] The guide device includes a shell, a return spring, a fixed block, and a second threaded rod. The shell is a rectangular frame. Fixed blocks are symmetrically arranged on the left and right sides of the shell. A triangular groove is opened on the fixed block. A gear is arranged in the shell. A rack is meshed on the outer side of the gear. The rack is fixedly connected to a fixed block, and the fixed block is slidably matched with the shell.

[0008] Preferably, the lifting device comprises a support column, a lifting rod and a positioning bolt. The support column is fixedly connected to the base, and the lifting rod is inserted into the support column.

[0013] By installing a lifting device on the base and accurately positioning it through positioning bolts, the operating table is lifted to the processing position. The base is firmly in contact with the ground, which improves stability. At the same time, by adjusting the first slide for lateral adjustment, the workpiece to be processed is aligned with the processing position of the thread rolling machine. Subsequently, a fixed block is moved by rotating the gear to drive the rack to place the workpiece to be processed in the triangular groove of the fixed block. The ball in the triangular groove fits tightly with the workpiece to be processed. Next, the gear is adjusted for clamping, and the second slide is adjusted to transport the workpiece to be processed longitudinally to start processing. After the processing is completed, the thread rolling machine is turned off and the processed workpiece is taken out. This device avoids manual placement of the workpiece for processing by personnel, reducing personal safety hazards. At the same time, after the device is positioned at the processing position, fine-tuning can be performed through the lead screw limit to ensure the stability of the processing quality. The setting of the ball can ensure that the workpiece rotates smoothly after being clamped by the thread rolling machine, and provide a guiding effect when cutting the thread to ensure processing accuracy.
