Description

Technical Field

[0001] This utility model belongs to the field of laser cutting equipment technology, specifically relating to a platform locking device. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] The parallel exchange platform laser cutting machine adopts a dual-station design, enabling rapid exchange of two platforms through a parallel linkage mechanism to improve production efficiency. In this mechanism, the front and rear platforms are linked by a chain to achieve positional interchange, completing alternating operations of cutting and loading. However, once the platforms reach their designated positions, they must remain absolutely still: the cutting platform must be stable and vibration-free during processing, while the loading platform is prone to swaying when subjected to impact loads (such as heavy sheet metal placement). Due to the mechanical linkage between the two platforms, the vibration of the loading platform is transmitted to the cutting platform, directly affecting cutting accuracy and surface quality.

[0004] To address the aforementioned issues, there are two traditional solutions. One is to disconnect the mechanical connection between the two platforms. However, due to limitations in the rough machining precision of the platform frames, it is difficult to guarantee consistent positioning during resetting after disconnection. The other is a mechanical fixing method, which involves rigidly locking the platforms using cylinders. The large cylinder clamping method suffers from insufficient effective locking force due to the large installation space and the angle between the clamping force direction and the applied force direction. While the small cylinder pin method has a compact structure, the low machining precision of the platforms makes matching the pin holes difficult, requiring repeated adjustments and corrections, increasing assembly complexity and maintenance costs. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a platform locking device, offering a platform locking solution with high rigidity and low error sensitivity, thus solving the problems of poor stability of the linkage mechanism under static working conditions and low platform machining accuracy.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: This utility model provides a platform locking device, including: a track base, a platform frame, and a locking mechanism; the locking mechanism includes a fixed seat and a telescopic pressing block, the fixed seat is disposed on the platform frame, the telescopic pressing block is composed of a pressing block and a housing, the pressing block can reciprocate relative to the housing, the housing is disposed on the track base; one end of the pressing block is wedge-shaped and is inserted into the fixed seat for fixation; the moving direction of the pressing block is perpendicular to the moving direction of the platform frame.

[0007] As a further implementation, the track base is a box girder structure, and support legs are fixedly installed at both ends; a movable track is provided on one side of the track base, and the movable track is arranged along the length direction of the track base.

[0008] As a further implementation, the platform frame is a rectangular frame structure welded from square steel pipes. The rectangular frame structure consists of crossbeams and end beams. There are two end beams, which are respectively set at both ends of the crossbeams. A plurality of rollers are evenly arranged near the lower part of the end beams. The rollers are rotatably fixed to the end beams by fasteners and rotate along the moving track.

[0009] As a further implementation, an end plate is provided at the end of the end beam, and reinforcing ribs are also provided on the end plate and the side wall of the end beam; the fixing seat is fixedly mounted on the end plate by fasteners.

[0010] As a further implementation, the fixed base includes a base plate, a U-shaped base, and a guide rod. The U-shaped base is fixedly mounted on the base plate, and the base plate is fixed to the end plate by fasteners. The guide rod is located at the opening of the U-shaped base and is cylindrical in shape, used to cooperate with the wedge surface of the clamping block, so that the platform frame moves to a designated position.

[0011] As a further implementation, the radial cross-section of the clamping block is rectangular or polygonal, allowing the clamping block to reciprocate linearly within the housing.

[0012] As a further implementation, a telescopic cylinder is provided at the other end of the clamping block. One end of the telescopic cylinder is connected to the clamping block, and the other end is connected to the track base, both of which are connected by fasteners.

[0013] As a further implementation, the housing is composed of a channel steel structure and a cover plate. The radial cross-section of the channel steel is the same as the radial cross-section of the clamping block. A fixing lug is provided on the outer side of one end of the channel steel. The fixing lug is fixed to the side wall of the track base by fasteners. The cover plate is installed at the opening of the channel steel by fasteners, so that the housing forms a closed tubular structure.

[0014] As a further implementation, a solenoid valve is provided on the side of the end plate near the end beam of the housing. The solenoid valve is connected to the telescopic cylinder through an air circuit system and is used to control the movement and stopping of the cylinder.

[0015] As a further implementation, there are two track bases, respectively located at both ends of the platform frame, and each track base is equipped with a locking mechanism.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are: This invention fixes a telescopic clamping block to a track base, and a fixing seat to a platform frame. The platform frame moves along the telescopic track base, and the moving direction of the clamping block is perpendicular to the moving direction of the platform frame. This ensures that the left and right sides of the fixing seat are tightly fitted to the left and right sides of the clamping block. The wedge-shaped end of the clamping block is inserted into the fixing seat, generating two forces that act on the fixing seat respectively, preventing the fixing block from moving. The clamping block, guided by the fixing seat, creates a perfectly fixed environment between the platform frame and the track base, thereby ensuring that the platform frame and the track base meet the set positional accuracy.

[0017] In this invention, a solenoid valve is provided on the side of the end plate near the end beam of the housing. The solenoid valve is connected to the telescopic cylinder through an air circuit system. When the platform frame moves to be exactly close to the side where the housing is located, the solenoid valve is triggered. The solenoid valve opens the air circuit, pushes the piston in the telescopic cylinder forward, and at the same time drives the pressing block to extend out along the tubular slide formed by the housing and enter the fixed seat, maintaining the continuous thrust of the telescopic cylinder on the pressing block.

The locking mechanism 3 includes a fixed seat 5 and a telescopic clamping block 4. The fixed seat 5 is disposed on the platform frame 2. The telescopic clamping block 4 consists of a clamping block 4 and a housing. The clamping block 4 can reciprocate relative to the housing, which is disposed on the track base 1. One end of the clamping block 4 is wedge-shaped and is inserted into the fixed seat 5 for fixation. The moving direction of the clamping block 4 is perpendicular to the moving direction of the platform frame 2. By using the wedge-shaped clamping block 4 and the guiding effect of the fixed seat 5, the platform frame 2 and the track base 1 are fixed in a stationary environment. During the process of the wedge surface being inserted into the fixed seat 5, the fixed seat 5 will drive the platform frame 2 to move slowly and finally fix it, thereby ensuring that the platform frame 2 and the track base 1 meet the set positional accuracy and improve the processing accuracy of the platform.

[0023] As a further implementation, the track base 1 has a box girder structure and is fixedly provided with legs at both ends; a movable track is provided on one side of the track base 1, and the movable track is arranged along the length direction of the track base 1.

[0024] As a further implementation, the platform frame 2 is a rectangular frame structure welded from square steel pipes. The rectangular frame structure consists of crossbeams and end beams. There are two end beams, which are respectively set at both ends of the crossbeams. A plurality of rollers are evenly arranged near the lower part of the end beams. The rollers are rotatably fixed to the end beams by fasteners and rotate along the moving track.

[0025] As a further implementation, an end plate is provided at the end of the end beam, and reinforcing ribs are also provided on the end plate and the side wall of the end beam; the fixing seat 5 is fixedly mounted on the end plate by fasteners.

[0026] As a further implementation, the fixed base 5 includes a base plate, a U-shaped base, and a guide rod. The U-shaped base is fixedly mounted on the base plate, and the base plate is fixed to the end plate by fasteners. The guide rod is located at the opening of the U-shaped base. The guide rod is cylindrical and is used to cooperate with the wedge surface of the clamping block 4, so that the platform frame 2 moves to a designated position.

[0027] As a further implementation, the radial cross-section of the clamping block 4 is rectangular or polygonal, so that the clamping block 4 can move linearly back and forth in the housing.

[0028] As a further implementation, a telescopic cylinder 9 is provided at the other end of the clamping block 4. One end of the telescopic cylinder 9 is connected to the clamping block 4, and the other end is connected to the track base 1, and both are connected by fasteners.

[0029] As a further implementation, the housing is composed of a channel steel structure 6 and a cover plate 7. The radial cross-section of the channel steel is the same as the radial cross-section of the clamping block 4. A fixing ear plate 8 is provided on the outer side of one end of the channel steel. The fixing ear plate 8 is fixed to the side wall of the track base 1 by fasteners. The cover plate 7 is installed at the opening of the channel steel by fasteners, so that the housing forms a closed tubular structure.

[0030] As a further implementation, a solenoid valve is provided on one side of the end plate near the end beam of the housing. The solenoid valve is connected to the telescopic cylinder 9 through an air circuit system and is used to control the movement and stopping of the cylinder.

[0031] As a further implementation, there are two track bases 1, which are respectively set at both ends of the platform frame 2, and each track base 1 is provided with a locking mechanism 3.

[0032] Working principle: The telescopic cylinder 9 is fixed on the track base 1, and the fixed seat 5 is fixed on the platform frame 2. The platform frame 2 moves along the telescopic track base 1. When the platform frame 2 moves to be exactly close to the side where the housing is located, the solenoid valve is triggered. The solenoid valve opens the air passage and pushes the piston in the telescopic cylinder 9 forward. At the same time, it drives the pressing block 4 to extend out along the tubular slide formed by the housing and enter the fixed seat 5, so that the fixed seat 5 and the pressing block 4 are tightly fitted from left to right and right, and cannot sway from left to right. The fixed seat 5 is rigidly connected to the platform frame 2. The wedge-shaped end of the pressing block 4 is inserted into the fixed seat 5, which will generate two forces that act on the fixed seat 5 respectively, so that the fixed block cannot move. In order to keep this force acting continuously, the direct thrust of the cylinder is needed to push the pressing block 4 through the guiding effect of the fixed seat 5 so that the platform frame 2 and the track base 1 form a fixed environment that is completely still, so that the platform frame 2 and the track base 1 meet the set positional accuracy.

Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
