The above-mentioned tapping machine is inconvenient to transport materials, and the material is prone to shaking and offset during the feeding process. Summary of the invention

[0004] Purpose of the present invention: In order to overcome the defects of the prior art, the present invention provides a copper sleeve tapping machine tool, which is convenient for clamping and feeding materials and can avoid shaking.

[0005] The technical solution of the present invention is as follows: a copper sleeve tapping machine tool comprises a workbench and a tapping machine head for processing threads on copper sleeves at a processing position, and also comprises a feed rail and a clamping mechanism, wherein the feed rail is used for multiple copper sleeves to pass through in sequence, the feed rail has a feed port and a discharge port for a single copper sleeve to pass through, and the clamping mechanism comprises a first large clamping block and a second large clamping block that can cooperate to clamp a single copper sleeve, the opposite sides of a pair of large clamping blocks have a long arc-shaped concave surface that matches the outer periphery of the copper sleeve, the first large clamping block can be telescopically passed through the discharge port, the second large clamping block is located at the processing position, and has a telescopically arranged small clamping block inside, the small clamping block has a short arc-shaped concave surface that matches the front side of the copper sleeve on the opposite side of the first large clamping block, the small clamping block extends backwards to cooperate with the first large clamping block to clamp the copper sleeve at the discharge port, and drives the copper sleeve forward to press against the second large clamping block, and the pair of large clamping blocks cooperate to clamp the copper sleeve at the processing position.

[0006] By adopting the above technical scheme, when in use, the material is fed through the feed rail, and the discharge port is for a single copper sleeve to pass through. The small clamping block first extends out to contact the copper sleeve. Since the small clamping block is small and the short arc-shaped concave surface on it has less contact surface with the outer periphery of the copper sleeve, it only contacts the front side of the copper sleeve and does not extend to the upper and lower ends of the copper sleeve, which can avoid the small clamping block from being inserted outside the upper and lower ends of the copper sleeve. The small clamping block will not pry the copper sleeve, and the small clamping block can facilitate the copper sleeve to be pushed into the long arc-shaped concave surface of the first large clamping block at the rear. At this time, the small clamping block and the first large clamping block cooperate to stably clamp the copper sleeve at the discharge port, and then the clamped copper sleeve is stably fed forward, and the copper sleeve is clamped by a pair of large clamping blocks.

[0007] This prevents the large clamp from contacting the copper sleeve first, because the lower copper sleeve will be pressed on the workbench and directly contacted by the upper copper sleeve, and the upper and lower ends of the large clamp will have thick walls, resulting in the long arc concave surface on it and the copper sleeve being misaligned in the upper and lower positions, making it inconvenient to insert the large clamp into the upper and lower ends of the copper sleeve, and the lower end of the large clamp is required to pry the copper sleeve up.

[0008] The present invention is further configured that the second large clamping block has a receiving cavity therein for receiving the small clamping block, and the small clamping block is recessed or flush with the long arc-shaped concave surface of the second large clamping block after being retracted.

[0009] By adopting the above further arrangement, it is prevented that the small clamping block protrudes and affects the cooperation of a pair of large clamping blocks in clamping the copper sleeve.

[0010] The present invention is further configured as follows: the feed rail has a vertical track, the vertical track can accommodate at least two vertically arranged copper sleeves, and the discharge port is arranged at the lower end of the vertical track.

[0011] By adopting the above further arrangement, it is convenient for multiple copper sleeves to fall downward one by one, and it is convenient to press the bottom copper sleeve on the workbench to prevent it from rolling away from the discharge port.

[0012] The present invention is further configured as follows: a concave hole is provided on the bottom wall corresponding to the discharge port, a convex ball and a spring are provided in the concave hole, the spring is located between the convex ball and the bottom wall of the concave hole so that the upper end of the convex ball extends out of the concave hole, the upper end of the convex ball can be blocked at the front side of the copper sleeve of the discharge port, and the convex ball is also compressed and retracted into the concave hole.

[0013] By further configuring as described above, the convex ball is blocked at the front side of the copper sleeve at the discharge port to effectively prevent it from rolling forward. When the clamped copper sleeve is then conveyed forward, the convex ball can be squeezed to enter the concave hole.

[0014] The present invention is further provided that the copper sleeve is blocked by a row of convex balls, which has a good effect of blocking the copper sleeve.

[0015] The present invention is further configured as follows: the upper and lower ends of the long arc-shaped concave surface of the first large clamping block are pointed, and the upper surface of the upper end thereof also has an inclined insertion surface.

[0016] The above further configuration is adopted to facilitate the first large clamping block to be inserted outside the upper and lower ends of the copper sleeve.

[0017] The present invention is further configured as follows: a workbench is provided on the workbench, a first large clamping block and a first driving member driving the first large clamping block to telescope and slide forward and backward are slidably provided on the rear end of the frame, a support platform for supporting a feed rail is also provided on the rear end of the frame, a second large clamping block and a second driving member driving a small clamping block on the second large clamping block to telescope and slide forward and backward are installed on the front end of the frame, the frame has a unloading port below the processing position, and a unloading bin corresponding to the unloading port is also installed on the frame.

[0018] By further configuring the above, the integrated components of the rack are used to facilitate the integrated installation of the clamping block, the feed rail, etc., and the unloading is also carried out through the unloading bin.

[0019] The present invention is further configured as follows: the feed rail has a vertical rail and an inclined rail extending backward from the upper end of the vertical rail; the support platform has a support plate and a table plate installed on the upper end of the support plate; the table plate is arranged at an angle; the inclined rail is installed on the table plate by screws; the table plate has a waist-shaped hole 1 through which the screws are passed; the support plate is installed on the frame by screws; the support plate has a waist-shaped hole 2 through which the screws are passed.

[0020] By further configuring the above, the inclined rail is convenient for connecting to the feeding equipment at the rear for feeding, and the support table can be easily installed by sliding adjustment in the waist-shaped hole through screws.

[0021] The present invention is further provided with a pair of tapping heads which are arranged at both sides of the processing position, and the pair of tapping heads can process the double ends of the copper sleeve at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The second large clamp block 42 has a receiving cavity 421 for accommodating the small clamp block inside, and the small clamp block 43 is recessed or flush with the long arc-shaped concave surface 411 on the rear end of the second large clamp block 42 after retraction. A concave hole 321 is provided on the bottom wall corresponding to the discharge port 32, and a convex ball 322 and a spring 323 are provided in the concave hole 321. The spring 323 is located between the convex ball 322 and the bottom wall of the concave hole 321 so that the upper end of the convex ball extends out of the concave hole. The upper end of the convex ball 322 can be blocked at the front side of the copper sleeve of the discharge port, and the convex ball 322 is also compressed and retracted in the concave hole 321.

A pair of tapping heads 2 are provided on both sides of the processing position, and the pair of tapping heads 2 can process the double heads of the copper sleeve at the same time.

[0026] Specifically, the workbench 1 is provided with a stand 5, and a first large clamping block 41 and a first driving member 61 for driving the first large clamping block to telescope and slide forward and backward are slidably provided on the rear end of the stand 5.
