Description

Technical Field

[0001] The present invention relates to the technical field of automatic adjustment of chuck jaws, and particularly to a laser alignment adjustment device. Background Art

[0002] Compared with traditional cutting processes such as oxyacetylene and plasma, laser cutting has the advantages of high cutting speed, narrow cut width, small heat-affected zone, good perpendicularity of the cut edge, smooth cut edge, and a wide variety of materials that can be laser cut. With the rapid development of the market economy and the rapid progress of science and technology, laser cutting technology has been widely applied in fields such as automobiles, machinery, electricity, hardware, and electrical appliances.

[0003] During long-term operation of laser cutting, due to high-speed vibration and some minute changes caused by heat, etc., the laser will deviate from its original central position, affecting the cutting of pipes. Currently, the adjustment requires using tape to mark points to check the light spot, which is time-consuming and laborious, and it is also prone to deviation when observed by the naked eye. Therefore, a rotating seat is installed on the laser head fixing seat. The rotating seat has a positioning shaft, which is controlled by a servo motor and is equipped with a CCD camera. Through system program settings, when the CCD camera irradiates that the laser center point is deviated, adjustments are made. However, due to design defects, most of the jaws on the existing chucks cannot be adjusted, which makes the machining accuracy of the workpiece worse and worse during subsequent processing. Now, a laser alignment adjustment device is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the prior art, and a laser alignment adjustment device is proposed.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

A correction seat for correcting the clamping position of the clamping members is provided at the bottom of the clamping members. Fixed corner blocks are provided at the four corners of the protective disc. The bottom of the correction seat is connected to a double-acting hydraulic cylinder through a connecting block, and the two output ends of the double-acting hydraulic cylinder are respectively fixedly connected to the fixed corner blocks on both sides.

[0007] Preferably, the fixed corner blocks are connected to the protective disc located above through screws, and the fixed corner blocks are connected to the protective disc located below through columns.

[0008] Preferably, the correction seat is arranged on the outer surface of the protective disc located above and is in sliding contact with the protective disc.

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly defined and limited, the terms "installation", "provided with", "sleeved / connected", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0019] Referring to Figures 1-3 , a laser alignment adjustment device includes a protective cover 1. Protective discs 2 are provided at both the upper and lower ends of the protective cover 1. A plurality of rectangular moving openings 3 are formed in the protective disc 2 at the upper end. A plurality of clamping members 4 are arranged in pairs on the upper surface of the protective disc 2. A correction seat 5 for correcting the clamping position of the clamping member 4 is provided at the bottom of the clamping member 4. Further, the correction seat 5 is arranged on the outer surface of the protective disc 2 at the upper side and is in sliding contact with the protective disc 2. The correction seat 5 can move relative to the protective disc 2 to achieve the adjustment effect. A guide rail seat 10 is fixedly connected to the bottom of the protective disc 2. A slide rail 11 adapted to the guide rail seat 10 is fixedly connected to the side wall of the double-acting hydraulic cylinder 8. Among them, through the cooperation between the slide rail 11 and the guide rail seat 10, it can ensure that the equipment is in a stable state during movement.

[0020] Fixing angle blocks 6 are provided at the four corners of the protective disc 2. Further, the fixing angle blocks 6 are connected to the protective disc 2 at the upper side by screws, and the fixing angle blocks 6 are connected to the protective disc 2 at the lower side by columns 9, so that the fixing angle blocks 6 are in a fixed state. When the distance between the double-acting hydraulic cylinder 8 and the fixing angle blocks 6 changes, the double-acting hydraulic cylinder 8 will fine-tune the clamping member 4.

[0021] The bottom of the correction seat 5 is connected to a double-acting hydraulic cylinder 8 through a connecting block 7. The hydraulic shafts at both ends of the double-acting hydraulic cylinder 8 are respectively controlled by hydraulic valves. It can achieve single control or simultaneous control, and its moving distance is set through the system program. The two output ends of the double-acting hydraulic cylinder 8 are respectively fixedly connected to the fixing angle blocks 6 on both sides.

[0022] Further, a mating port adapted to the rectangular moving opening 3 is formed in the guide rail seat 10. Among them, the mating port is hidden below the guide rail seat 10, which can effectively prevent dust from entering the interior and achieve the protection effect. The slide rail 11 is fixedly connected to the connecting block 7 that sequentially penetrates the mating port and the rectangular moving opening 3. The other side of the connecting block 7 is fixedly connected to the correction seat 5. A plurality of hydraulic connection ports for external hydraulic pipes are provided on the fixing angle blocks 6. Among them, the external hydraulic pipes are connected to an external hydraulic device with power, and the hydraulic device is programmed and controlled through the system.

[0023] Specifically, during operation, when the CCD camera installed on the laser head irradiates and the laser center point is offset, the biaxial hydraulic cylinder 8 is controlled through the setting and calculation of the system program by the hydraulic device, so that the output end of the biaxial hydraulic cylinder 8 is adjusted. When it is adjusted, the distance between the biaxial hydraulic cylinder 8 and the fixed angle block 6 changes. Since the fixed angle block 6 is fixed on the protective disc 2, the biaxial hydraulic cylinder 8 will drive the slide rail 11 connected thereto to move, so that the correction seat 5 connected to the slide rail 11 through the connecting block 7 is adjusted in position, so that the clamping member 4 located on the correction seat 5 is finely adjusted, thus ensuring the machining accuracy of the workpiece.

[0024] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
