[0019] In order to make the purpose, technical scheme and advantages of the present application more clear and explicit, the present application will be further described in detail below with reference to the drawings and embodiments.

[0020] The material clamp device is a device or mechanism for clamping and fixing various materials, which is usually composed of a gas cylinder, a clamp plate, a connecting component, etc. The gas cylinder serves as a power source and is connected to a compressed air system through an air pipe. The clamp plate is installed at the end of the piston rod of the gas cylinder and is used to directly clamp the material. When compressed air enters the rod cavity or the rodless cavity of the gas cylinder, the piston and the piston rod are pushed to move, and the piston rod drives the clamp plate to move, thereby realizing the clamping or loosening action of the material. The movement speed and clamping force of the clamp plate can be accurately controlled by controlling the on-off, pressure and flow of the compressed air. However, the existing material clamp device does not have a collision prevention function and is prone to collision with the plate during operation, resulting in damage.

[0021] Reference Figure 1 , Figure 1 It is a structural schematic diagram of a rear material clamp with collision prevention.

[0022] A rear material clamp with collision prevention is provided, which comprises a gantry 100, a first driving motor 200, a second driving motor 300, a first material clamping assembly and a second material clamping assembly. The gantry 100 is arranged on the rack of an external device, the first driving motor 200 and the second driving motor 300 are arranged on the two feet of the gantry 100 respectively, and are used to drive the gantry 100 to move. The first material clamping assembly and the second material clamping assembly are arranged on the cross beam of the gantry 100, and are used to fix the plate. The gantry is mainly composed of a column and a cross beam, the column is vertically installed on the base or workbench of the cutting machine, the cross beam connects the two columns to form a stable frame structure, which provides support for the cutting device, positioning device, etc. of the cutting machine, and ensures the stability and accuracy of these components during the working process.

[0023] In operation, after the first material clamping assembly and the second material clamping assembly fix the plate, the first driving motor 200 and the second driving motor 300 operate to move along the rack of the external device. The height of the material clamping assembly can be adjusted by the first gas cylinder 410 and the third gas cylinder 510, which avoids the collision of the material clamp caused by the plate transported from the rear, effectively avoids the damage of the device, makes the processing process of the plate more smooth, and improves the production efficiency.

[0024] As a further improvement of the above technical solution, in some further specific examples, the output end of the first driving motor 200 is connected with a first gear, and the first gear is engaged with the rack of the external device.

[0025] As a further improvement of the above technical solution, in some further specific examples, the output end of the second driving motor 300 is connected with a second gear, and the second gear is engaged with the rack of the external device.

[0026] As a further improvement of the above technical solution, in some further specific examples, the first material clamping assembly comprises: a first single-axis movement assembly 400, a first air cylinder 410, a second air cylinder 420, a third air cylinder 430, a first material clamp 440, and a second material clamp 450. The first single-axis movement assembly 400 and the cylinder body of the first air cylinder 410 are fixedly installed on the cross beam of the gantry 100, the second air cylinder 420 and the third air cylinder 430 are installed on the moving plate of the first single-axis movement assembly 400, the telescopic end of the first air cylinder 410 is connected with the moving plate of the first single-axis movement assembly 400, the telescopic end of the second air cylinder 420 is connected with the upper clamp of the first material clamp 440, and the telescopic end of the third air cylinder 430 is connected with the upper clamp of the second material clamp 450.

[0027] As a further improvement of the above technical solution, in some further specific examples, the second material clamping assembly comprises: a second single-axis movement assembly 500, a fourth air cylinder 510, a fifth air cylinder 520, a sixth air cylinder 530, a third material clamp 540, and a fourth material clamp 550. The second single-axis movement assembly 500 and the cylinder body of the fourth air cylinder 510 are fixedly installed on the cross beam of the gantry 100, the fifth air cylinder 520 and the sixth air cylinder 530 are installed on the moving plate of the second single-axis movement assembly 500, the telescopic end of the fourth air cylinder 510 is connected with the moving plate of the second single-axis movement assembly 500, the telescopic end of the fifth air cylinder 520 is connected with the upper clamp of the third material clamp 540, and the telescopic end of the sixth air cylinder 530 is connected with the upper clamp of the fourth material clamp 550.

[0028] The operation of the air cylinder is based on the principle of air pressure transmission, and compressed air is used as the power source. The air compressor compresses air to make it have high pressure energy, and the compressed air is delivered to the air cylinder through a pipeline. In this embodiment, an SC air cylinder is used. The inside of the SC air cylinder is divided into a rod cavity and a rodless cavity by a piston. When compressed air is input from the rodless cavity, the rod cavity exhausts, and the pressure difference between the two cavities of the air cylinder acts on the piston to form a force that overcomes the resistance load and pushes the piston to move, causing the piston rod to extend. When the rod cavity is filled with air and the rodless cavity is exhausted, the piston rod retracts. If the rod cavity and the rodless cavity alternate between air intake and exhaust, the piston can achieve reciprocating linear motion.

[0029] As a further improvement of the above technical solution, in some further specific examples, the upper clamp of each of the first material clamp 440, the second material clamp 450, the third material clamp 540, and the fourth material clamp 550 is provided with anti-slip patterns. The anti-slip patterns can further enhance the clamping effect, making the material clamp device hold the board more firmly. In some work scenarios that require frequent loading and unloading of boards, the anti-slip patterns can ensure that the board does not slip out of the material clamp device under certain clamping force, improving the safety and stability of the work.

[0030] As a further improvement of the above technical solution, in some further specific examples, the first driving motor 200 and the second driving motor 300 are AC servo motors.

[0031] As a further improvement of the above technical solution, in some further specific examples, the first driving motor 200 and the second driving motor 300 are speed reducers. Speed reducers mainly realize the function of speed reduction and torque increase through gear transmission, worm transmission, planetary transmission and the like. Taking the most common gear speed reducer as an example, it utilizes different gears to mesh with each other, according to the principle of gear transmission, when the driving gear (small gear) drives the driven gear (large gear) to rotate, the rotation speed of the driven gear will be lower than that of the driving gear, while the torque will be increased accordingly, and the speed reduction ratio is equal to the ratio of the number of teeth of the driven gear to the number of teeth of the driving gear.

[0032] Although the description of the present application has been quite detailed and particularly described with respect to the described embodiments, it is not intended to be limited to any of these details or embodiments or any particular embodiment, but should be considered to effectively cover the intended scope of the present application by reference to the appended claims, taking into account the prior art, providing a broad interpretation of the claims. In addition, the present application is described above in embodiments that the inventors can foresee, the purpose of which is to provide a useful description, and non-essential modifications to the present application that have not yet been foreseen can still represent equivalent modifications of the present application.
