TECHNICAL FIELD

[0001] The present application relates to the technical field of pipe cutting machine, in particular to a T-shaped heavy load side-hung type laser pipe cutting machine and a self-adjusting method thereof. BACKGROUND

[0002] The laser pipe cutting machine refers to a machine for cutting pipe materials by using laser, which is widely used in the field of metal processing. The T-shaped heavy load side-hung type laser pipe cutting machine is a laser cutting device based on Y-axis, which is arranged according to the characteristics of large axial length and small radial length of pipe materials. The chuck assembly is hung on the support frame and can slide along the Y-axis to drive the pipe materials.

[0003] The driving of the chuck is generally realized by the gear walking along the laid rack. However, for the pipe materials with large axial length, the laid slide is too long, and the gear will inevitably fluctuate in the radial direction during the walking process. For example, the tooth skipping caused by the tooth side gap will make the chuck move inward, which affects the pipe cutting accuracy. SUMMARY

[0004] In view of the problem that the chuck will inevitably fluctuate in the radial direction during the walking process along the track, affecting the pipe cutting accuracy in the prior art, the present application provides a T-shaped heavy load side-hung type laser pipe cutting machine and a self-adjusting method, and the specific technical solutions are as follows:

[0005] On one hand, the present application provides a T-shaped heavy load side-hung type laser pipe cutting machine, which comprises a side slide frame, a sliding plate slidingly installed on the side slide frame, a chuck mounting plate hung on the sliding plate, and a chuck installed on the chuck mounting plate. A compensation mechanism is arranged between the sliding plate and the chuck mounting plate.

[0006] The compensation mechanism comprises a cavity two opened in the sliding plate, a rotating disc rotatably connected in the cavity two, the rotating center of the rotating disc is eccentrically arranged, a slide is concentrically opened on the rotating disc, a slide rod is slidingly connected in the slide, the other end of the slide rod is connected with a connecting rod, the connecting rod is connected with the chuck mounting plate, and the rotating disc is driven to eccentrically rotate by an external force to force the relative movement of the sliding plate and the chuck mounting plate and compensate the radial displacement of the sliding plate.

[0007] As a further technical solution of the present application, the compensation mechanism further comprises a cavity one opened in the sliding plate, a walking gear rotatably connected in the cavity one, a resisting column penetrating through the sliding plate, the resisting column has a gear slot section, the walking gear engages with the gear slot section, and one end of the resisting column abuts against the side slide frame.

[0008] A connecting column is coaxially connected on the walking gear, and the other end of the connecting column is inserted into the cavity two and connected with the rotating center of the rotating disc.

[0009] As a further technical scheme of the present application, the distance variation of the slide bar and the connecting column is L1, the displacement of the slide plate is L2, and L1=L2.

[0010] As a further technical scheme of the present application, the slide bar, the connecting column and the center of the rotating disc are coplanar.

[0011] As a further technical scheme of the present application, a compensation cavity is formed on the chuck mounting plate, and the insertion end of the resisting column extends and is inserted into the compensation cavity.

[0012] As a further technical scheme of the present application, a ball groove is formed on one end of the resisting column towards the side slide frame, and a ball is arranged to roll in the ball groove and abut against the side slide frame.

[0013] As a further technical scheme of the present application, a guide column is arranged on the end surface of the chuck mounting plate towards the slide plate, a guide column groove corresponding to the guide column is formed on the end surface of the slide plate towards the chuck mounting plate, and the guide column is inserted into the guide column groove.

[0014] On the other hand, the present application also provides a self-adjusting method of the T-shaped heavy-load side-hung laser pipe cutting machine, and the specific steps are as follows:

[0015] S1, the slide plate is driven to move towards the side slide frame and generate a displacement L2, the walking gear walks on the resisting column and drives the connecting column to rotate, thereby driving the rotating disc to eccentrically rotate around the connecting column;

[0016] S2, the slide rail rotates with the rotating disc and drives the slide bar, the connecting rod and the chuck mounting plate to move away from the side slide frame and generate a displacement L1, wherein L2=L1, so as to compensate the displacement of the slide plate and make the chuck mounting plate stationary relative to the side slide frame.

[0017] The present application has the following advantages:

[0018] In the present application, the traditional bolt connection mode of the slide plate and the chuck mounting plate is changed, the relative movement between the slide plate and the chuck mounting plate is allowed, the compensation mechanism is used to make the chuck mounting plate generate a movement vector opposite to the movement direction of the slide plate, the displacement of the slide plate is equal to the displacement of the chuck mounting plate relative to the slide plate, the radial movement of the slide plate is compensated, the chuck mounting plate is stationary relative to the side slide frame, and the stability during the sliding of the chuck is ensured.

DETAILED DESCRIPTION

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

[0029] Figure 1 A structural schematic diagram of the T-shaped heavy-load side-hung laser pipe cutting machine is shown. Figure 2 A structural schematic diagram at the chuck 140 is shown. Figure 1 and Figure 2 In the T-shaped heavy-load side-hung laser pipe cutting machine, the side carriage 110 is slidably connected with the slide plate 120, the side end of the slide plate 120 is slidably connected with the chuck mounting plate 130, the other end of the chuck mounting plate 130 is installed with the chuck 140, the chuck 140 is hung on one side of the side carriage 110, and the slide plate 120 is further installed with a walking motor, which can drive the chuck 140 to move along the trajectory of the side carriage 110.

[0030] Generally, the sliding plate 120 and the slide rail on the side slide frame 110 have a gap, that is, the sliding plate 120 can move radially relative to the side slide frame 110, and under normal circumstances, the sliding plate 120 is pulled to be farthest from the side slide frame 110 under the influence of the self-gravity of the chuck 140; and after fluctuation, the sliding plate 120 approaches the side slide frame 110, thereby driving the chuck 140 to move radially.

[0031] Figure 3 A structural diagram between the sliding plate 120 and the chuck mounting plate 130 is shown; Figure 4 A structural diagram of the compensation mechanism 200 is shown; Figure 3 And Figure 4 In the compensation mechanism 200, a cavity one 210 is arranged between the sliding plate 120 and the chuck mounting plate 130, the cavity one 210 is rotatably connected with a walking gear 220, a resisting column 230 is penetrated through the sliding plate 120, the resisting column 230 has a gear slot section 231, the walking gear 220 engages the gear slot section 231, and one end of the resisting column 230 abuts against the side slide frame 110; because the resisting column 230 abuts against the side slide frame 110, when the sliding plate 120 approaches the side slide frame 110, the resisting column 230 is limited and cannot move synchronously with the sliding plate 120, that is, the resisting column 230 is static and moves relatively with the sliding plate 120, and because the gear slot section 231 engages the walking gear 220, the walking gear 220 rolls along the track of the resisting column 230 in the process that the sliding plate 120 slides along the track of the resisting column 230; in the present application, the traditional bolt locking mode between the sliding plate 120 and the chuck mounting plate 130 is changed, so that the sliding plate 120 and the chuck mounting plate 130 are allowed to move relatively, and the movement of the sliding plate 120 drives the walking gear 220 to rotate, thereby serving as a force for driving the chuck mounting plate 130 to move subsequently.

[0032] Because the chuck mounting plate 130 is connected with the sliding plate 120, when the sliding plate 120 moves, the chuck mounting plate 130 moves and bends the pipe along with it; in view of the technical problem, Figure 5 A structural diagram of the rotating disc 260 is shown; Figure 6 A structural diagram of the sliding rod 270 and the connecting rod 280 is shown; Figure 5 And Figure 6In the compensation mechanism 200, a cavity two 250 is formed in the sliding plate 120, a connecting column 240 is coaxially connected to the walking gear 220, the other end of the connecting column 240 is inserted into the cavity two 250 and is eccentrically connected with a rotating disc 260, a slide 261 is concentrically formed in the rotating disc 260, a slide rod 270 is slidably connected in the slide 261, the other end of the slide rod 270 is connected with a connecting rod 280, and the connecting rod 280 is connected with the chuck mounting plate 130. The connecting column 240 transmits the rotation of the walking gear 220 to the rotating disc 260, drives the rotating disc 260 and the slide 261 to eccentrically rotate around the connecting column 240, and because the slide rod 270 slides in the slide 261, the slide rod 270 gradually moves away from the connecting column 240, that is, the chuck mounting plate 130 gradually moves away from the sliding plate 120, and the relative movement between the two is generated. The displacement amount of the slide rod 270 relative to the connecting column 240 is used to compensate for the displacement amount of the sliding plate 120, so that the chuck mounting plate 130 relatively moves with the sliding plate 120 when the sliding plate 120 moves, thereby reducing the relative fluctuation between the chuck mounting plate 130 and the side sliding frame 110 and reducing the bending degree of the pipe. The distance change amount of the slide rod 270 relative to the connecting column 240 is L1, the displacement amount of the sliding plate 120 is L2, and L1=L2. That is, the difference between the distance between the slide rod 270 and the connecting column 240 after rotation and the distance between the slide rod 270 and the connecting column 240 before rotation is equal to the displacement amount of the sliding plate 120. In this way, the distance change amount of the slide rod 270 relative to the connecting column 240 can completely compensate for the displacement amount of the sliding plate 120, so that the chuck mounting plate 130 is stationary relative to the side sliding frame 110, and the chuck 140 can remain stable when the sliding plate 120 fluctuates. The centers of the slide rod 270, the connecting column 240 and the rotating disc 260 are coplanar. That is, even if a pulling force is applied to the connecting rod 280, the rotating disc 260 cannot be driven to rotate, that is, the rotating disc 260 is a one-way transmission structure that can only be driven by the connecting column 240. In this way, under normal circumstances, the chuck 140 cannot be separated from the sliding plate 120 by its own gravity. Although the two allow relative movement, they always have a firm connection relationship. A compensation cavity 132 is formed in the chuck mounting plate 130, and the insertion end of the abutting column 230 extends into the compensation cavity 132. Because the sliding plate 120 moves at the beginning, the walking gear 220 has not yet rotated, and the chuck mounting plate 130 still moves synchronously with the sliding plate 120, the compensation cavity 132 is provided to compensate for the initial error, so that the chuck mounting plate 130 and the abutting column 230 allow relative movement.

[0033] Figure 7 A structural diagram of the abutting column 230 towards one end of the side sliding frame 110 is shown. Figure 7In the embodiment, the abutting column 230 is provided with a ball groove 232 at one end of the side sliding frame 110, and the ball groove 232 is provided with a ball 233 rolling therein, and the ball 233 abuts against the side sliding frame 110; the ball 233 is in contact with the side sliding frame 110, and when the abutting column 230 moves along the track of the side sliding frame 110, the rolling of the ball 233 causes the rolling friction between the abutting column 230 and the side sliding frame 110.

[0034] Figure 8 An exploded structural schematic diagram of the slide plate 120 and the chuck mounting plate 130 is shown; Figure 8 In the embodiment, the chuck mounting plate 130 is provided with a guide column 131 at an end surface facing the slide plate 120, and the slide plate 120 is provided with a guide column groove 121 corresponding to the guide column 131 at an 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 track of the slide plate 120 and the chuck mounting plate 130; and the movement of the slide plate 120 and the chuck mounting plate 130 in the vertical plane is avoided.

[0035] The self-adjusting method of the T-shaped heavy-load side-hung type laser pipe cutting machine specifically includes the following steps:

[0036] S1, the slide plate 120 is driven to move towards the side sliding frame 110 and generate a displacement L2, so that the walking gear 220 walks on the abutting column 230 and drives the connecting column 240 to rotate, thereby driving the rotating disc 260 to eccentrically rotate around the connecting column 240;

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

[0038] The above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto.
