Description

Technical Field

[0001] The utility model relates to a pipe processing device, more specifically, it relates to a ball guide device of a round pipe cutting machine. Background Art

[0002] In the process of round tube production, in order to make the round tube match the length required during production, it is usually necessary to cut the pipe fittings to make them reach the appropriate length. Therefore, the cutting of the pipe fittings is an important step in the processing process. In the process of pipe fitting cutting, a grinding wheel saw is usually used. Although the cutting speed of the grinding wheel saw is fast, it will vibrate and deviate due to the relative force with the pipe fitting during the cutting process, which reduces the cutting accuracy. At the same time, after the cutting is completed, due to the granularity of the grinding wheel surface, the cross-section flatness of the pipe fitting after cutting is poor, so the surface of the incision needs to be polished after the cutting is completed, resulting in reduced production efficiency.

[0003] The existing cutting device also has a laser tube cutting machine, which works on the principle of cutting round tubes through a high-power and high-density laser beam. The cut is smooth and the cutting efficiency is high, and it is widely used in the field of round tube processing.

[0004] At present, the clamping method for cutting round tubes in the market usually adopts double-end clamping and fixing, and the cutting head is used to cut the part between the two clamping mechanisms to produce round tubes of appropriate length. This clamping method requires frequent clamping and loosening of the round tube after each cutting, which is difficult to operate. In addition, the two ends of the round tube are clamped during the cutting process. Usually, the adjustment of the cutting position is achieved by manually adjusting the position of the cutting head. For processes with high precision requirements, the adjustment is difficult, resulting in low precision of the cut round tube, which affects the use effect. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a ball guide device for a round tube cutting machine which has high cutting accuracy, a stable cutting process, and is convenient for moving and guiding the tube.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a ball guide device of a round tube cutting machine, comprising a frame, a driving device is provided at one end of the frame, the driving device is used to clamp and transport the pipe, and a cutting device is also provided at the other end of the frame, the cutting device is used to cut the pipe, the cutting device comprises a positioning assembly and a cutting assembly, the positioning assembly comprises a fixed frame and a positioning piece arranged on the fixed frame, and the cutting assembly comprises a slide arranged on one side of the fixed frame and a cutting head arranged on the slide.

[0007] The utility model is further configured as follows: the positioning member includes a group of clamping slides arranged on a fixed frame, a mounting plate is provided on the clamping slide, and the mounting plates are symmetrically distributed on the clamping slide with the cutting head as the central axis, a vertical plate is also provided on the mounting plate, a fixed plate is provided between the vertical plate and the mounting plate, a positioning plate is also provided on the fixed plate, the positioning plate is "Y"-shaped, and a plurality of mounting grooves are provided on the positioning plate, the mounting grooves are symmetrically distributed on the positioning plate, and balls are provided in the mounting grooves.

[0008] Preferably, a rack is provided at the bottom of the mounting plate, and the rack is transmission-connected to a gear disposed inside the clamping slide.

[0009] Preferably, a buffer spring is provided between the mounting groove and the positioning plate.

[0010] The utility model is further configured as follows: the driving device comprises a driving slide arranged on the frame and a plurality of clamping parts arranged on the driving slide.

[0011] The utility model is further configured as follows: a pushing cylinder is provided at the rear end of the slide, a cutting plate is provided between the slide and the cutting head, the cutting head is arranged on the cutting plate and cuts the pipe by pushing the cylinder.

[0012] By adopting the above technical solution, the pipe fitting is clamped by the driving slide and the clamping piece in the driving device. After the pipe fitting is clamped, the driving device pushes the pipe fitting through the positioning component. The positioning component clamps and fixes the pipe fitting through the positioning piece to prevent the vibration of the pipe fitting during the rotation of the pipe fitting, which causes poor flatness of the cutting cut. In addition, during the movement of the driving component, it is guided by the ball inside the positioning piece to prevent the pipe fitting from rubbing against the positioning piece during the rotation and sliding process, thereby avoiding damage to the pipe fitting.

[0013] Furthermore, in order to position and guide the pipe fittings, a clamping slide is provided on the fixed frame, the mounting table slides on the clamping slide, and the mounting plate is symmetrically distributed on the clamping slide with the cutting head as the central axis. At the same time, a gear rack is provided between the bottom of the mounting plate and the clamping slide. The gear can drive the rack transmission during the transmission process, so that the position of the mounting table on the clamping slide can be synchronously approached or moved away, and during the adjustment of the mounting table, the central axis is always located on the extension line of the cutting head, and in order to adapt to pipe fittings of different diameters, the positioning plate is set to a "Y" shape. After the positioning plate slides on the clamping slide, the pipe fitting is clamped and positioned by the ball bearings on the positioning plate, thereby minimizing the radial runout of the pipe fitting during the processing.

[0014] At the same time, in the process of processing the pipe fittings, in order to prevent the vibration caused by the driving component driving the pipe fittings to rotate and during the cutting process, a buffer spring is arranged between the installation groove and the positioning plate. The buffer spring allows the ball to have a reserved displacement along the axis of the spring installation after contacting the pipe body, thereby preventing the outer wall of the pipe body and the ball from having a rigid collision during the cutting process. At the same time, when the driving device drives the pipe fittings, the balls are arranged in four directions outside the pipe body. The balls can roll synchronously when the pipe fittings move, reducing the difficulty of moving the pipe fittings and improving the displacement accuracy of the driving component, so that the cutting of the pipe fittings does not require manual adjustment, reducing the difficulty of operation and improving the efficiency and accuracy of cutting.

[0015] In addition, the cutting head is driven by a pushing cylinder behind the slide, so that the cutting head can slide left and right on the fixed frame to prevent the diameter of the pipe from being too large so that the pipe collides with the cutting head during movement. At the same time, when cutting the pipe, the driving device can drive the pipe to rotate while keeping the position fixed. During the rotation processing of the pipe, the ball can position and guide the pipe, thereby increasing the stability of the pipe during processing. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The positioning member 8 includes a group of clamping slides 11 arranged on the fixed frame 7, the clamping slide 11 is provided with a mounting plate 12, and the mounting plate 12 is symmetrically distributed on the clamping slide 11 with the cutting head 10 as the central axis, the mounting plate 12 is also provided with a vertical plate 13, a fixing plate 14 is provided between the vertical plate 13 and the mounting plate 12, and a positioning plate 15 is also provided on the fixing plate 14, the positioning plate 15 is "Y"-shaped, and a plurality of mounting grooves 16 are provided on the positioning plate 15, the mounting grooves 16 are symmetrically distributed on the positioning plate 15, and balls 17 are provided in the mounting grooves 16.

[0027] Preferably, a rack 18 is provided at the bottom of the mounting plate 12 , and the rack 18 is transmission-connected to a gear disposed inside the clamping slide 11 .

[0028] Preferably, a buffer spring 19 is further provided between the mounting groove 16 and the positioning plate 15 .

[0029] The driving device 2 includes a driving slide 20 arranged on the frame 1 and a plurality of clamping parts 21 arranged on the driving slide 20, and a pushing cylinder 22 is provided at the rear end of the slide 9, and a cutting plate 23 is also provided between the slide 9 and the cutting head 10, and the cutting head 10 is arranged on the cutting plate 23 and realizes cutting of the pipe 3 by pushing the cylinder 22.

[0030] The pipe fitting 3 is clamped by the driving slide 20 and the clamping member 21 in the driving device 2. After the pipe fitting 3 is clamped, the driving device 2 pushes the pipe fitting 3 through the positioning component 5. The positioning component 5 clamps and fixes the pipe fitting 3 through the positioning member 8 to prevent the vibration of the pipe fitting 3 during the rotation of the pipe fitting 3 from causing poor flatness of the cut. In the process of moving the driving component, it is guided by the ball 17 inside the positioning member 8 to prevent the pipe fitting 3 from rubbing against the positioning member 8 during the rotation and sliding, thereby avoiding damage to the pipe fitting 3.

[0031] Furthermore, in order to position and guide the pipe fitting 3, a clamping slide 11 is provided on the fixing frame 7, the mounting table slides on the clamping slide 11, and the mounting plate 12 is symmetrically distributed on the clamping slide 11 with the cutting head 10 as the central axis. At the same time, a gear rack 18 is provided between the bottom of the mounting plate 12 and the clamping slide 11.

After the positioning plate 15 slides on the clamping slide 11, the pipe fitting 3 is clamped and positioned by the ball 17 on the positioning plate 15, thereby minimizing the radial runout of the pipe fitting 3 during the processing.

[0032] At the same time, during the processing of the pipe fitting 3, since the movement and rotation of the pipe fitting 3 are driven by the driving assembly, during the rotation of the pipe fitting 3, due to the long distance between the driving assembly and the positioning assembly 5, the pipe fitting 3 in the positioning assembly 5 has a large vibration amplitude, which causes the device to cause an uneven cut when cutting the pipe fitting 3. In order to prevent the vibration caused by the driving assembly driving the pipe fitting 3 to rotate and during the cutting process, a buffer spring 19 is arranged between the mounting groove 16 and the positioning plate 15. The buffer spring 19 allows the ball 17 to have a reserved displacement along the axis of the spring installation after contacting the pipe body, thereby preventing the outer wall of the pipe body from rigidly colliding with the ball 17 during the cutting process. At the same time, when the driving device 2 drives the pipe fitting 3, the ball 17 is arranged in four directions outside the pipe body. The ball 17 can roll synchronously when the pipe fitting 3 moves, which reduces the difficulty of moving the pipe fitting 3 and improves the displacement accuracy of the driving assembly, so that the cutting of the pipe does not require manual adjustment, reduces the difficulty of operation, and improves the efficiency and accuracy of cutting.

[0033] In addition, the cutting head 10 is driven by the pushing cylinder 22 behind the slide 9, so that the cutting head 10 can slide left and right on the fixed frame 7 to prevent the diameter of the pipe 3 from being too large so that the pipe 3 collides with the cutting head 10 during movement. At the same time, when cutting the pipe 3, the driving device 2 can drive the pipe to rotate while keeping the position fixed. During the rotation processing of the pipe 3, the ball 17 can position and guide the pipe 3, thereby increasing the stability of the pipe 3 during processing.
