Description

Technical Field

[0001] The present invention relates to the technical field of the rear chuck of a laser pipe cutting machine, and particularly to a dust-proof rear chuck of a laser pipe cutting machine with an integral barrel that can be clamped in different directions. Background Art

[0002] Laser processing is an emerging industry developed this year, and the rear chuck is a very key device of a laser pipe cutting machine. Currently, there are mainly the following 4 problems with the rear chuck of a laser pipe cutting machine:

[0003] ①Regarding the dust-proof problem of high-temperature metal dust; currently, the accuracy of the jaws inside the rear chuck is adjusted through a set adjustment window, so the chuck cannot be fully sealed, which directly affects the reliability of the chuck's operation and is an urgent problem to be solved currently.

[0004] ②The problem of establishing the axial reference line of the rear chuck; currently, there is no unified reference for the axis of the rear chucks popular in the market, which is inconvenient for users to adjust the accuracy. This problem affects the commissioning and installation accuracy of the whole machine and is a common requirement of the majority of users.

[0005] ③The problem of externally adjustable slider clearance; this problem is the key to achieving dust-proof sealing. Once external adjustment is achieved, it is expected to achieve full-seal dust-proof.

[0006] ④The problem of externally adjustable jaw accuracy. In the past, a window was opened on the barrel wall for debugging inside the chuck, which was inconvenient to adjust and had low adjustment efficiency.

[0007] Therefore, we propose a dust-proof rear chuck of a laser pipe cutting machine with an integral barrel that can be clamped in different directions to solve the above problems. Summary of the Invention

[0008] The purpose of the present invention is to provide a dust-proof rear chuck of a laser pipe cutting machine with an integral barrel that can be clamped in different directions to solve the deficiencies in the prior art.

[0009] To achieve the above purpose, the present invention adopts the following technical solutions:

[0010] A dust-proof rear chuck of a laser pipe cutting machine with an integral barrel that can be clamped in different directions proposed by the present invention includes a barrel and a disk fixed to the end face of the barrel. A cylinder block is arranged inside the barrel, a front piston and a rear piston are installed in the cylinder block, and four connecting rods are arranged at the telescopic end of the cylinder block. One end of the connecting rod is rotatably connected to the cylinder block;

[0011] The disk body is provided with a transition plate, and double-layer sliders are slidably mounted on the four sides of the disk body, and one side of the disk body is provided with four swing rods, the swing rods are "V" shaped, and the middle part of the swing rods is rotatably connected with the disk body, and one end of the four swing rods is rotatably connected with the ends of the above four connecting rods, and the other ends of the four swing rods are respectively inserted into the four double-layer sliders, and the swing rods are slidably matched with the double-layer sliders;

[0012] The four double-layer sliding blocks can be detachably mounted with claws.

[0013] The present invention proposes a dust-proof rear clamp for a whole-cylinder laser tube cutting machine that can be clamped in different directions. Preferably, four guide blocks are fixed on the inner wall of the cylinder, the four guide blocks are evenly distributed, and the vertical cross-section of the guide blocks is "U" shaped, and the four connecting rods are respectively inserted in the guide blocks, and the connecting rods and the guide blocks are slidably matched to improve the stability of the connecting rods when they move, thereby improving the stability of the clamping claws when they move.

[0014] The present invention proposes a dust-proof rear clamp for a whole-barrel laser tube cutting machine that can be clamped in different directions. Preferably, a bayonet is provided at one end of the double-layer slider close to the rocker arm, one end of the rocker arm is inserted into the bayonet, and the rocker arm and the double-layer slider are slidably matched to facilitate the movement of the double-layer slider by the rocker arm.

[0015] The present invention proposes a dust-proof rear clamp for a whole-barrel laser tube cutting machine that can be clamped in different directions. Preferably, a straight guide rail surface is fixed on the disk body, the double-layer slider is installed on the straight guide rail surface, and inclined guide rail working surfaces are opened on both sides of the double-layer slider.

[0016] The present invention proposes a dust-proof rear clamp for a whole-barrel laser tube cutting machine that can be clamped in different directions. Preferably, a friction plate is arranged between the double-layer slider and the straight guide rail surface, and an adjusting screw hole is penetrated through the double-layer slider. Eccentric shaft holes are arranged on both sides of the adjusting screw hole to facilitate the adjustment of the position of the double-layer slider.

[0017] The present invention proposes a dust-proof rear clamp for a whole-barrel laser tube cutting machine that can be clamped in different directions. Preferably, a plurality of installation steps are provided on the upper surface of the double-layer slider, and the clamping claws are fixed on the installation steps by bolts, so as to facilitate adjustment of the position of the clamping claws to expand the range of objects clamped by the device.

[0018] The present invention proposes a dust-proof rear clamp for a whole-barrel laser tube cutting machine that can be clamped in different directions. Preferably, an anti-slip layer is provided on the outer wall of each of the clamping claws to increase the friction force when clamping with the object and improve the tightness of the clamping with the object.

[0019] A dust-proof rear clamp for a laser tube cutting machine with an integral barrel and capable of opposite-direction clamping. Preferably, four openings are evenly formed in the transition plate, and the four double-layer sliders are inserted into the openings to position the double-layer sliders and improve the stability of the movement of the double-layer sliders.

[0020] A dust-proof rear clamp for a laser tube cutting machine with an integral barrel and capable of opposite-direction clamping. Preferably, a front piston and a rear piston are installed in the cylinder block, and its air circuit is a four-channel. The two pistons move independently. Through external control, the two pistons can achieve the same-direction movement or be converted into opposite-direction movement. In actual use, according to the different pipes of the tube cutting machine, the same-direction clamping or opposite-direction clamping can be conveniently realized.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. The double-layer sliders are adopted. The inclined working surface guide rails are adopted in the structure of the double-layer sliders. The upper layer of the double-layer sliders is above the integral panel, and the lower layer of the double-layer sliders, that is, the working surface of the guide rails, is below the integral panel. It is very difficult for dust to break through the gaps of the integral panel and enter the lower sliders, thus achieving an excellent dust-proof effect. In addition, the integral barrel structure is adopted. Since the adjustment window is cancelled, the dust-proof around is completely sealed, and the problem of dust-proof of the rear clamp is completely solved.

[0023] 2. After adopting the integral barrel structure design, there are no any connecting parts from the rear flange to the front end face. Therefore, for the axial direction, the outer wall of the integral barrel naturally forms the axial reference, solving the problem of the user's precision alignment and being beneficial to the overall machine debugging.

[0024] 3. In this device, by tightening the adjusting screw downward, the friction plate is pushed out downward. After the friction plate contacts the flat guide rail surface, the double-layer slider is pushed upward by the reaction force until the gap between the two working surfaces of the inclined guide rail working surface is close to zero. By combining the inclined guide rail with the adjustable friction plate, the adjustment of the gap between the guide rail and the slider outside is realized.

[0025] 4. In this device, the eccentric shaft is combined with the transition plate. By adjusting the eccentric shaft, the transition plate moves back and forth slightly. After the adjustment is in place, the transition plate is pressed tightly on the double-layer slider, thereby realizing the external adjustment of the claw. There is no need to make adjustments again when the claw changes gears, improving the adjustment efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] A transition plate 7 is provided on the disc body 6, and double-layer sliders 8 are slidably installed on the four sides of the disc body 6. Four openings are evenly opened on the transition plate 7. Four double-layer sliders 8 are inserted in the openings to position the double-layer sliders 8 and improve the stability of the movement of the double-layer sliders 8. A straight guide surface 13 is fixed on the disc body 6. The double-layer sliders 8 are installed on the straight guide surface 13, and inclined guide working surfaces 12 are opened on both sides of the double-layer sliders 8. A friction plate 12 is provided between the double-layer sliders 8 and the straight guide surface 13. The device pushes the friction plate 14 downward by tightening the adjusting screw downward. After the friction plate 14 contacts the straight guide rail surface 13, the double-layer slider 8 is pushed upward by the reaction force until the gap between the two working surfaces of the inclined guide rail working surface 12 is close to zero.
