Technical Field

[0001] The invention relates to the technical field of tube cutting machines, in particular to a T-type heavy-load side-mounted laser tube cutting machine and a self-adjustment method of the T-type heavy-load side-mounted laser tube cutting machine. Background Art

[0002] Laser tube cutting machine refers to a machine that uses laser to cut tubes. It is widely used in the field of metal processing. The T-type heavy-load side-mounted laser tube cutting machine is a laser cutting device arranged based on the Y-axis to target the characteristics of large axial length and small radial length of tubes. The chuck assembly is side-mounted on the support frame and can slide along the Y-axis to drive the tube.

[0003] The chuck is generally driven by a gear that moves along a laid rack. However, for pipes with a large axial length, the laid slideway is too long, and the gear will inevitably fluctuate in the radial direction during its movement. For example, tooth jumping caused by the tooth side clearance will cause the chuck to move inward, affecting the pipe cutting accuracy. Summary of the invention

[0004] In view of the problem in the prior art that the chuck inevitably experiences radial fluctuations while moving along the track, which affects the pipe cutting accuracy, the present invention provides a T-shaped heavy-load side-mounted laser pipe cutting machine and a self-adjustment method. The specific technical scheme is as follows:

[0005] On the one hand, the present application provides a T-type heavy-load side-mounted laser tube cutting machine, comprising a side slide frame, a slide plate slidably mounted on the side slide frame, a chuck mounting plate side-mounted on the slide plate, and a chuck mounted on the chuck mounting plate, wherein a compensation mechanism is provided between the slide plate and the chuck mounting plate;

[0006] The compensation mechanism includes a second chamber opened in the slide, a turntable is rotatably connected in the second chamber, the rotation center of the turntable is eccentrically set, a slideway is concentrically opened on the turntable, a slide rod is slidably connected in the slideway, the other end of the slide rod is connected to a connecting rod, the connecting rod is connected to the chuck mounting plate, and the turntable is driven by an external force to rotate eccentrically, forcing the slide and the chuck mounting plate to move relative to each other and compensate for the radial displacement of the slide.

[0007] As a further technical solution of the present invention, the compensation mechanism further includes a chamber 1 opened in the slide, a traveling gear is rotatably connected in the chamber 1, a support column is passed through the slide, a tooth groove section is provided on the support column, the traveling gear meshes with the tooth groove section, and one end of the support column contacts the side slide frame;

[0008] A connecting column is coaxially connected to the traveling gear, and the other end of the connecting column is inserted into the second chamber and connected to the rotation center of the turntable.

[0009] As a further technical solution of the present invention, the distance change between the sliding rod and the connecting column is L1, the displacement of the sliding plate is L2, and L1=L2.

[0010] As a further technical solution of the present invention, the centers of the sliding rod, the connecting column and the turntable are coplanar.

[0011] As a further technical solution of the present invention, a compensation cavity is provided on the chuck mounting plate, and the insertion end of the abutment column extends and is inserted into the compensation cavity.

[0012] As a further technical solution of the present invention, a ball groove is formed at one end of the abutment column facing the side slide frame, and balls are rolled in the ball groove, and the balls abut against the side slide frame.

[0013] As a further technical solution of the present invention, the end surface of the chuck mounting plate facing the slide plate is provided with a guide post, the end surface of the slide plate facing the chuck mounting plate is provided with a guide post groove corresponding to the guide post, and the guide post is inserted into the guide post groove.

[0014] On the other hand, the present application also provides a self-adjustment method for a T-type heavy-load side-mounted laser tube cutting machine, and the specific steps are as follows:

[0015] S1, the slide is driven to move toward the side slide and produces a displacement L2, so that the travel gear moves on the abutment column and drives the connecting column to rotate, thereby driving the turntable to rotate eccentrically around the connecting column;

[0016] S2, the slideway rotates with the turntable and drives the slide rod, the connecting rod and the chuck mounting plate to move to the side away from the side slide and generate a displacement L1, wherein L2=L1, to compensate for the displacement of the slide plate and keep the chuck mounting plate stationary relative to the side slide.

[0017] The beneficial effects of the present invention are as follows:

[0018] In the present application, the traditional bolt connection method between the slide plate and the chuck mounting plate is changed to allow relative movement between the slide plate and the chuck mounting plate, and a compensation mechanism is used to make the chuck mounting plate have a motion vector in the opposite direction of the slide plate, and the displacement of the slide plate is equal to the displacement of the chuck mounting plate relative to the slide plate, thereby compensating for the radial movement of the slide plate, making the chuck mounting plate stationary relative to the side slide, and ensuring the stability of the chuck during sliding.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0029] Figure 1 The overall structural diagram of the T-type heavy-duty side-mounted laser tube cutting machine is shown; Figure 2 A schematic diagram of the structure at the chuck 140 is shown; Figure 1 and Figure 2 In the figure, the T-shaped heavy-load side-mounted laser tube cutting machine includes a side slide 110, on which a slide plate 120 is slidably connected, and a chuck mounting plate 130 is slidably connected to the side end of the slide plate 120, and a chuck 140 is mounted on the other end of the chuck mounting plate 130, so that the chuck 140 is side-mounted on one side of the side slide 110, and a travel motor is also installed on the slide plate 120, which can drive the chuck 140 to move along the trajectory of the side slide 110.

[0030] Normally, there is a gap between the slide 120 and the slide rails on the side slide 110, that is, the slide 120 can move radially with the side slide 110, and under normal circumstances, affected by the gravity of the chuck 140, the slide 120 is pulled to the farthest distance from the side slide 110; after fluctuations occur, the slide 120 will approach the side slide 110, thereby driving the chuck 140 to move radially.

[0031] Figure 3 A schematic diagram of the structure between the slide plate 120 and the chuck mounting plate 130 is shown; Figure 4 shows a schematic structural diagram of the compensation mechanism 200; Figure 3 and Figure 4 In the embodiment, a compensation mechanism 200 is arranged between the slide plate 120 and the chuck mounting plate 130, and the compensation mechanism 200 includes a chamber 210 opened in the slide plate 120, and a traveling gear 220 is rotatably connected in the chamber 210, and a support column 230 runs through the slide plate 120, and a tooth groove section 231 is provided on the support column 230, and the traveling gear 220 meshes with the tooth groove section 231, and one end of the support column 230 contacts the side slide frame 110; because the support column 230 contacts the side slide frame 110, when the slide plate 120 approaches the side slide frame 110, the support column 230 is restricted. However, it cannot move synchronously with the skateboard 120, that is, the support column 230 is stationary and moves relative to the skateboard 120. Since the tooth groove section 231 is meshed with the travel gear 220, the travel gear 220 rolls along the trajectory of the support column 230 during the sliding movement of the skateboard 120 along the trajectory of the support column 230. In the present application, the bolt locking method of the traditional skateboard 120 and the chuck mounting plate 130 is changed to allow the skateboard 120 and the chuck mounting plate 130 to move relative to each other, and at the same time, the movement of the skateboard 120 itself is used to drive the travel gear 220 to rotate, so as to serve as the subsequent driving force for the chuck mounting plate 130 to move.

[0032] Since the chuck mounting plate 130 is connected to the slide plate 120, when the slide plate 120 moves, the chuck mounting plate 130 will move accordingly and bend the pipe; in view of this technical problem, Figure 5 A schematic diagram of the structure of the rotating disk 260 is shown; Figure 6 A schematic diagram of the structure of the sliding rod 270 and the connecting rod 280 is shown; Figure 5 and Figure 6In the embodiment, the compensation mechanism 200 further includes a chamber 250 provided in the slide plate 120, a connecting column 240 is coaxially connected to the travel gear 220, the other end of the connecting column 240 is inserted into the chamber 250 and eccentrically connected to a turntable 260, a slideway 261 is coaxially provided on the turntable 260, a slide bar 270 is slidably connected in the slideway 261, the other end of the slide bar 270 is connected to a connecting rod 280, and the connecting rod 280 is connected to the chuck mounting plate 130; the connecting column 240 transmits the rotation of the travel gear 220 to the turntable 260, and drives the turntable 260 and the slideway 261 to rotate around the connecting column 241. 0 eccentric rotation, and because the slide bar 270 slides in the slideway 261, the slide bar 270 will gradually move away from the connecting column 240, that is, the chuck mounting plate 130 will gradually move away from the slide plate 120, and the two will move relative to each other, and the displacement of the slide bar 270 relative to the connecting column 240 is used to compensate the displacement of the slide plate 120, so that when the slide plate 120 moves, the chuck mounting plate 130 will move relative to the slide plate 120, thereby reducing the relative fluctuation between the chuck mounting plate 130 and the side slide frame 110, and reducing the bending degree of the pipe; the distance change between the slide bar 270 and the connecting column 240 is L1, and the displacement of the slide plate 120 is L2, L1=L2; That is to say, the difference between the distance between the sliding bar 270 and the connecting column 240 after the rotation and the distance between the sliding bar 270 and the connecting column 240 before the rotation is equal to the displacement of the slide plate 120. In this way, the change in the distance between the sliding bar 270 and the connecting column 240 can completely compensate for the displacement of the slide plate 120, so that the chuck mounting plate 130 is stationary relative to the side slide 110, so that the chuck 140 can remain stable when the slide plate 120 fluctuates; the centers of the sliding bar 270, the connecting column 240 and the turntable 260 are coplanar; that is to say, even if a pulling force is applied to the connecting bar 280, the turntable 260 cannot be driven to rotate, that is, the turntable 260 is only A one-way transmission structure that can be driven by the connecting column 240, in this way, under normal circumstances, the chuck 140 cannot be separated from the slide plate 120 by its own gravity. Although the two are allowed to move relative to each other, they always have a firm connection relationship; a compensation cavity 132 is provided on the chuck mounting plate 130, and the insertion end of the support column 230 extends and is inserted into the compensation cavity 132; because the slide plate 120 is at the beginning of the movement and the traveling gear 220 has not yet rotated, the chuck mounting plate 130 will still slightly move synchronously with the slide plate 120, and therefore a compensation cavity 132 is provided to compensate for the initial error, so that relative movement is allowed between the chuck mounting plate 130 and the support column 230.

[0033] Figure 7 A schematic diagram of the structure of the end of the support column 230 facing the side sliding frame 110 is shown; Figure 7In the figure, a ball groove 232 is formed at one end of the support column 230 facing the side slide frame 110, and a ball 233 is rolled in the ball groove 232, and the ball 233 contacts the side slide frame 110; the ball 233 contacts the side slide frame 110, and when the support column 230 moves along the trajectory of the side slide frame 110, the rolling of the ball 233 causes rolling friction between the two.

[0034] Figure 8 A schematic diagram of the exploded structure of the slide plate 120 and the chuck mounting plate 130 is shown; Figure 8 In the embodiment, the chuck mounting plate 130 has a guide column 131 on its end surface facing the slide plate 120, and the slide plate 120 has a guide column groove 121 corresponding to the guide column 131 on its end surface facing the chuck mounting plate 130, and the guide column 131 is inserted into the guide column groove 121; the guide column 131 and the guide column groove 121 are used to limit the relative movement trajectory of the slide plate 120 and the chuck mounting plate 130 to prevent the two from moving in the vertical plane.

[0035] The self-adjustment method of the T-type heavy-load side-mounted laser tube cutting machine is as follows:

[0036] S1, the slide plate 120 is driven to move toward the side slide frame 110 and generates a displacement L2, so that the travel gear 220 travels on the stop column 230 and drives the connecting column 240 to rotate, thereby driving the rotating disk 260 to rotate eccentrically around the connecting column 240;

[0037] S2, the slide 261 rotates with the turntable 260 and drives the slide rod 270, the connecting rod 280 and the chuck mounting plate 130 to move to the side away from the side slide 110 and generate a displacement L1, wherein L2=L1, to compensate for the displacement of the slide plate 120 and make the chuck mounting plate 130 stationary relative to the side slide 110.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
