Technical Field

[0001] The utility model relates to the technical field of thread machines, in particular to a drum - type small thread machine. Background Technique

[0002] The drum - type small thread machine is a mechanical device used for producing small - diameter threads, and is usually used for processing various small parts and fasteners.

[0003] This machine forms the workpiece by rotating the drum and uses rolling technology to form threads on the material surface.

[0004] It has the following advantages:

[0005] High efficiency: It can process threads quickly and continuously, with high production efficiency;

[0006] High precision: By precisely controlling the movement and pressure of the drum, high - quality and consistent threads can be ensured;

[0007] Wide application range: It can process a variety of materials, including steel, aluminum, copper, etc., and is suitable for different specifications of threads;

[0008] Convenient maintenance: It has a compact structure and is easy to maintain and service.

[0009] The drum - type thread machine is widely used in many industries such as mechanical manufacturing, automotive parts, electronic equipment, etc., and is one of the important equipment for producing threaded parts.

[0010] Currently, for conventional drum - type thread machines, when the drum is advancing, it only relies on a single cylinder to push or a lead - screw structure to move horizontally. In this way, during long - term use, horizontal movement is prone to frictional wear, and frequent lubrication and maintenance are required. Otherwise, it will cause jamming during tapping. Therefore, it is necessary to optimize the structure of the drum's movement to improve the service life of the thread machine and reduce the trouble of frequent maintenance. Summary of the Utility Model

[0011] The purpose of the utility model is to solve the above - mentioned disadvantages in the prior art and propose a drum - type small thread machine.

[0012] To achieve the above purpose, the utility model adopts the following technical scheme:

[0013] Design a drum - type small thread machine, including a base. Above the base, there is a left - right moving platform. The upper end of the left - right moving platform is covered with a support plate, and the lower end of the support plate is fixedly assembled with the surface of the left - right moving platform through screws;

[0014] Above the said support plate, there are two symmetrically distributed front-back moving platforms. A transition plate is fixedly arranged on the surface of the front-back moving platform, and a first motor is arranged above the transition plate.

[0015] Inside the first motor, there is a first rotating shaft for driving. The end of the first rotating shaft is fixedly connected with a shaft rod through a coupling. A roller is fixedly sleeved on the surface of the shaft rod, and tapping threads are arranged on the surface of the roller.

[0016] Specifically, several groups of first guide wheels are fixedly installed at the lower end of the left-right moving platform, and the surface of the first guide wheels is in rolling contact with the surface of the base.

[0017] Specifically, several groups of second guide wheels are fixed at the lower end of the front-back moving platform, and the surface of the second guide wheels is in rolling contact with the upper end of the transition plate.

[0018] Specifically, a first cylinder is arranged above the base. The outer wall surface of the first cylinder is fixedly assembled with the surface of the base through a bracket. Inside the first cylinder, there is a first piston rod for telescoping. The end of the first piston rod penetrates through the first cylinder and extends outwards. The other end of the first piston rod is fixedly connected with the surface of the left-right moving platform through a screw.

[0019] Specifically, a second cylinder is arranged above the support plate. The outer wall surface of the second cylinder is fixedly assembled with the surface of the base through a bracket. Inside the second cylinder, there is a second piston rod for telescoping. The end of the second piston rod penetrates through the second cylinder and extends outwards. The other end of the second piston rod is fixedly connected with the surface of the front-back moving platform through a screw.

[0020] Specifically, a second motor is also arranged at one end of the base. The outer wall surface of the second motor is fixedly assembled with the end of the base through a bracket. Inside the second motor, there is a second rotating shaft for driving. The end of the second rotating shaft is fixedly connected with a disc by welding.

[0021] Specifically, two symmetrically distributed third cylinders are fixed on the other side of the disc through a bracket. Inside the third cylinders, there are third piston rods for telescoping. The ends of the third piston rods penetrate through the third cylinders and extend outwards. The ends of the third piston rods are fixed with inner arc-shaped clamping seats.

[0022] The beneficial effects of the design scheme proposed by the present utility model in the application process are as follows:

[0023] 1. There are two symmetrically distributed drums with tapping threads set on them. They can move relative to the object, contact with the round rod, and perform thread processing on the rod. The left - right movement of the drums is driven by the telescopic movement of the first cylinder and assisted by the first guide wheels to reduce the frictional loss during movement. The front - back movement of the drums is driven by the telescopic movement of the second cylinder and assisted by the second guide wheels to reduce the frictional loss during movement.

[0024] 2. Driven by the second motor, the disc can rotate. Driven by the telescopic movement of the third cylinder, two clamping seats with inner arc surfaces can clamp and fix the round rod. Thus, when thread processing is carried out on the round rod, firm clamping can be ensured, and at the same time, rotation can be coordinated to complete the thread production around the round rod.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0031] Refer to Figures 1-4 , a drum - type small - thread machine, including a base 10. Above the base 10, there is a left - right moving table 11. The upper end of the left - right moving table 11 is covered with a support plate 12, and the lower end of the support plate 12 is fixedly assembled with the surface of the left - right moving table 11 through screws;

[0032] Above the support plate 12, there are two symmetrically distributed front and rear moving platforms 13. A transition plate 14 is fixedly arranged on the surface of the front and rear moving platform 13, and a first motor 15 is arranged above the transition plate 14;

[0033] Inside the first motor 15, there is a first rotating shaft for driving. The end of the first rotating shaft is fixedly connected with a shaft rod 17 through a coupling 16. A roller 18 is fixedly sleeved on the surface of the shaft rod 17, and tapping threads are arranged on the surface of the roller 18.

[0034] Furthermore, it should be noted that several groups of first guide wheels 20 are fixedly installed at the lower end of the left and right moving platform 11, and the surface of the first guide wheels 20 is in rolling contact with the surface of the base 10.

[0035] Through the rolling effect of the first guide wheels 20, the left and right movement friction loss of the left and right moving platform 11 when driving the roller 18 to move can be reduced.

[0036] Furthermore, it should be noted that several groups of second guide wheels 21 are fixed at the lower end of the front and rear moving platform 13, and the surface of the second guide wheels 21 is in rolling contact with the upper end of the transition plate 14.

[0037] Through the rolling effect of the second guide wheels 21, the front and rear movement friction loss of the front and rear moving platform 13 when driving the roller 18 to move can be reduced.

[0038] Furthermore, it should be noted that a first cylinder 30 is arranged above the base 10. The outer wall surface of the first cylinder 30 is fixedly assembled with the surface of the base 10 through a bracket. Inside the first cylinder 30, there is a first piston rod for telescoping. The end of the first piston rod extends outwards through the first cylinder 30. The other end of the first piston rod is fixedly connected with the surface of the left and right moving platform 11 through screws. When the first piston rod telescopes, it can drive the roller 18 to move back and forth, so as to adjust according to the position where the round rod needs tapping threads. The number of the first cylinders 30 is at least three and they are arranged side by side at equal distances to ensure the stable telescoping of the left and right moving platform 11.

[0039] Furthermore, it should be noted that a second cylinder 31 is arranged above the support plate 12. The outer wall surface of the second cylinder 31 is fixedly assembled with the surface of the base 10 through a bracket. Inside the second cylinder 31, there is a second piston rod for telescoping. The end of the second piston rod extends outwards through the inside of the second cylinder 31. The other end of the second piston rod is fixedly connected with the surface of the front and rear moving platform 13 through screws. Through the oppositely distributed second piston rods, the two rollers 18 can be brought into contact with the round rod to realize thread processing. The distribution number of the second cylinders 31 on one side is at least three and they are arranged at equal distances to ensure the stable movement of the front and rear moving platform 13.

[0040] Further, it should be noted that a second motor 40 is also provided at one end of the base 10. The outer wall surface of the second motor 40 is fixedly assembled with the end of the base 10 through a bracket. A second rotating shaft for driving is provided inside the second motor 40. A disc 41 is fixedly welded to the end of the second rotating shaft. The second motor 40 can drive the clamped round rod to rotate in cooperation through the second rotating shaft, so that thread processing can be stably carried out in one week.

[0041] Further, it should be noted that two symmetrically distributed third cylinders 42 are fixedly connected to the other side of the disc 41 through a bracket. A third piston rod for telescoping is provided inside the third cylinder 42. The end of the third piston rod extends outwards through the inside of the third cylinder 42. The end of the third piston rod is fixedly provided with an inner arc-shaped clamping seat 43. The clamping seat 43 can be appropriately lengthened according to the length of the round rod to ensure stable clamping of the round rod during processing.

[0042] Working mode: When thread processing of the round rod is required, one end of the round rod is butted against the disc 41 and arranged between the two clamping seats 43. Through the telescoping of the third piston rod of the third cylinder 42, the two clamping seats 43 can clamp and fix the round rod, and through the rotation of the second motor 40, the round rod can be driven to move in cooperation.

[0043] The clamping center of the round rod is always on the same horizontal line as the contact position between the two rollers 18. When the position of the thread processing needs to be adjusted, through the telescoping of the first piston rod of the first cylinder 30, the roller 18 can move relative to the rod to adjust the tapping position.

[0044] When tapping is required, through the telescoping of the second piston rod of the second cylinder 31, the two rollers 18 can move towards each other, and through the drive of the first motor 15, the rollers 18 can rotate, so as to contact the surface of the round rod. Through the continuous rotation and extrusion of the tapping thread and the smooth surface, thread forming is achieved.
