Description

Technical Field

[0001] The utility model belongs to the technical field of machine tool processing, and relates to a bar processing machine tool, in particular to a thread connection assembly mechanism of a bar processing machine tool. Background Art

[0002] The alignment accuracy requirement for bar processing is relatively high. Using a bar processing machine tool to produce can ensure the processing accuracy of the end screw holes. The thread connection is a bolt structure for connecting two bars, fixed at the end of one bar, and can be screwed into the screw hole at the end of the other bar to realize the splicing of the two bars. For example, a billiard cue is composed of multiple sections spliced together. The multiple sections are connected by thread connections, and the thread connection is a double-headed bolt structure. Threads are provided at the ends of the billiard cues, and the thread connections are screwed onto the billiard cues. Currently, the installation of the thread connections all adopts the manual installation method. After the billiard cue is tapped, the thread connection is then screwed on manually. The manual installation method has low efficiency, and during the process of screwing the thread connection, it is impossible to ensure the concentricity between the thread connection and the billiard cue. The inclination of the thread connection relative to the billiard cue will cause the overall bending of the billiard cue during multi-section splicing, affecting the product quality. Summary of the Utility Model

[0003] The purpose of the utility model is to address the above problems existing in the prior art and propose a thread connection assembly mechanism for a bar processing machine tool. The technical problem solved by the utility model is to directly complete the thread connection assembly on the bar processing machine tool.

[0004] The purpose of the utility model can be achieved by the following technical solutions:

[0005] A thread connection assembly mechanism for a bar processing machine tool. The bar processing machine tool includes a frame, a main shaft and a moving table installed on the frame. The feature is that this thread connection assembly mechanism includes a thread connection feeder and a thread connection loader. The thread connection feeder is installed on the frame. The thread connection feeder and the main shaft are on the same side of the thread connection loader. The thread connection feeder includes a feeding chute and a fixing structure that can fix the thread connection at the end of the feeding channel. The thread connection loader includes a driving motor and a connection head fixed on the motor shaft of the driving motor. The driving motor is installed on the moving table, and the moving table can drive the driving motor to move back and forth between the thread connection feeder and the main shaft. When the driving motor is aligned with the feeding channel, the connection head can approach the end of the feeding channel to be screwed and fixed with the thread connection located at the end of the feeding channel. When the driving motor is aligned with the main shaft, the connection head can approach the main shaft to screw the thread connection onto the bar and then separate from the thread connection.

[0006] The bar stock to be assembled is fixed by the main shaft, and the connecting teeth to be assembled are fed by the connecting tooth feeder. During use, the assembled connecting teeth are transferred to the end of the feeding chute, and the connecting teeth are pressed and positioned by the pressing structure. The moving table moves the connecting tooth loader to a position opposite to the connecting tooth feeder. The connecting head rotates through the driving motor, and the connecting head moves towards the connecting teeth at the end of the feeding chute. The fixed connecting teeth are screwed and fixed with the connecting head. After completion, the connecting head retreats. The moving table moves the connecting tooth loader to a position opposite to the main shaft, and the connecting head moves towards the main shaft. A threaded hole is provided on the bar stock, and the connecting head screws the connecting teeth located thereon into the threaded hole of the bar stock. After the connecting teeth are installed in place, the connecting teeth rotate in the opposite direction relative to the connecting head to achieve the separation of the connecting teeth from the connecting head. The connecting teeth on the connecting head are installed on the bar stock, realizing the direct completion of the connecting tooth assembly on the bar stock processing machine tool, improving the production efficiency, and ensuring the concentricity of the connecting teeth and the bar stock, thereby improving the product quality.

[0009] In the connecting tooth assembly mechanism of the above-mentioned bar stock processing machine tool, the connecting tooth feeder further includes a machine case, a stepped feeder fixed in the machine case, and a pushing cylinder. The stepped feeder includes a plurality of push plates arranged in a stepped manner. When the uppermost push plate is at a high position, it is aligned with the feeding chute. The pushing cylinder is fixed on the machine case and is located at the starting end of the feeding chute. The connecting teeth are sequentially sent to the feeding chute one by one through the stepped feeder, and then the connecting teeth are pushed to the end of the feeding chute by the cylinder rod of the pushing cylinder; the push plates of the stepped feeder are inclined, and when the uppermost push plate is at a high position, the connecting teeth on it will roll into the feeding channel.

[0010] In the tooth connection assembly mechanism of the above-mentioned bar processing machine tool, a channel groove in a "V" shape is provided on the feeding channel. The channel groove of this structure can more accurately position the tooth connection axially, enabling the tooth connection at the end of the feeding channel to be accurately positioned with the connecting head.

[0011] In the tooth connection assembly mechanism of the above-mentioned bar processing machine tool, a slide rail cylinder is further fixed on the moving table, and the driving motor is fixedly installed on the slide seat of the slide rail cylinder. The slide rail cylinder can drive the driving motor to move towards the main shaft or the feeding channel side. By controlling the connecting head to approach the feeding channel or the feeding channel separately through the moving cylinder, accurate picking and installation of the tooth connection can be achieved.

[0012] In the tooth connection assembly mechanism of the above-mentioned bar processing machine tool, a screw rod protrudes from the end of the connecting head. The connecting head of this structure can be adapted to the tooth connection with a counterbore, and the screw rod can be screwed and fixed with the counterbore of the tooth connection.

[0013] As another case, in the tooth connection assembly mechanism of the above-mentioned bar processing machine tool, a connection hole is opened at the end of the connecting head, and an internal thread is provided in the connection hole. The connecting head of this structure is adapted to a screw-shaped tooth connection, and the tooth connection can be screwed and fixed with the connection hole of the connecting head.

[0014] In the tooth connection assembly mechanism of the above-mentioned bar processing machine tool, a cross slide is installed on the machine frame, and the moving table is fixed on the cross slide. Through the cross slide, the free movement of the moving table on the horizontal plane can be realized, and the accurate movement of the tooth connection feeding machine can be achieved.
