Description

Technical Field

[0001] The utility model relates to the technical field of automobile roof cutting, and particularly relates to an ultrasonic cutting machine for automobile roofs. Background Art

[0002] An ultrasonic cutting machine converts high-frequency electric energy into ultrasonic vibration, which is transmitted to the material surface through a tool. The high-frequency vibration causes the material to be locally heated and separated rapidly, achieving non-edge cutting. Its advantages include a flat and burr-free cutting edge, little heat influence, wide applicability to materials such as metals and plastics, and environmentally friendly and energy-saving operation without coolant, improving production efficiency and material utilization rate.

[0003] The ultrasonic cutting machine with the publication number CN213061498U discloses an ultrasonic cutting machine for precise cutting. The ultrasonic cutting machine starts a distance sensor to detect the distance of the fabric, and a fixed block drives an installation sleeve to press a roller to fix the position of the fabric by extrusion. Although this device is provided with a fixing device for fixing materials, it requires an additional sensor to detect the position of the material. Therefore, an ultrasonic cutting machine for automobile roofs is proposed to solve the above problems. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides an ultrasonic cutting machine for automobile roofs, which has the advantages of being able to detect the roof reaching a specified position and fixing it.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] An ultrasonic cutting machine for automobile roofs includes a workbench. A conveyor belt is arranged on the workbench. An ultrasonic knife is above the workbench. Slide rails are arranged on both sides of the conveyor belt. Sliders are arranged on the slide rails. A baffle is arranged at the front end of the slider. A spring is arranged between the baffle and the slider. A towing wire is arranged on the baffle. The rear end of the slider is open. The towing wire passes through the opening of the slider. A pulley frame is arranged beside the slide rail. A pulley is installed on the pulley frame. The towing wire bypasses the pulley. The end of the towing wire is connected to a magnet block. A magnet seat is installed on the workbench at a position corresponding to the magnet block. After the baffle is pushed by the automobile roof, the front end of the towing wire moves backward, so that the end of the towing wire moves downward, making the magnet block approach and adsorb to the magnet block.

[0007] Further, the elastic force of the spring is greater than the gravity of the magnet block, and the sum of the magnetic force generated by the magnet block and the magnet seat and the gravity of the magnet block is greater than the elastic force of the spring.

[0008] Further, the distance between the magnet block and the magnet seat is equal to the compression length of the spring.

[0009] Furthermore, when the slider is working, the distance between the slider and the pulley frame is less than the distance between the slider and the pulley frame when the slider is idle.

[0010] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0011] 1. For the ultrasonic cutting machine for the automotive roof, by setting the slider, the baffle on the slider is used to detect whether the automotive roof reaches the designated position. When the baffle moves, the magnets are attracted together, thereby fixing the automotive roof. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0023] Please refer to Figure 1-2, An ultrasonic cutting machine for a car roof in this embodiment includes a workbench 1. There is a conveyor belt 11 on the workbench 1. Above the workbench, there is an ultrasonic knife 2. There are slide rails 3 on both sides of the conveyor belt 11. There are sliders 31 arranged on the slide rails 3. There is a baffle 311 at the front end of the slider 31. There is a spring 312 between the baffle 311 and the slider 31. There is a traction wire 313 on the baffle 311. The rear end of the slider 31 is open. The traction wire 313 passes through the opening of the slider 31. There is a pulley frame 4 beside the slide rail 3. There is a pulley 41 installed on the pulley frame 4. The traction wire 313 bypasses the pulley 41. The end of the traction wire 313 is connected to a magnet block 5. A magnet seat 51 is installed on the workbench 1 at a position corresponding to the magnet block 5. After the baffle 311 is pushed by the car roof 6, the front end of the traction wire 313 moves backward, so that the end of the traction wire 313 moves downward, causing the magnet block 5 to approach and adsorb to the magnet block 51.

[0024] Move the slider 31 to the detection position. After the conveyor belt 11 transports the car roof 6 to the detection position, the car roof 6 pushes the baffle 311. The front end of the traction wire 313 connected to the baffle 311 moves backward. The traction wire 313 changes direction through the pulley. The end of the traction wire 313 moves downward. The height of the magnet block 5 connected to the end of the traction wire 313 decreases, so that the magnet block 5 and the magnet seat 51 attract each other. The car roof 6 is fixed by the cooperation of the magnet block 5 and the magnet seat 51, and then processed with the ultrasonic knife 2.

[0025] Further, the elastic force of the spring 312 is greater than the gravity of the magnet block 5, and the sum of the magnetic force generated by the magnet block 5 and the magnet seat 51 and the gravity of the magnet block 5 is greater than the elastic force of the spring 312.

[0026] The elastic force of the spring 312 is greater than the gravity of the magnet block 5, so that when the car roof 6 does not push the baffle 311, the magnet block 5 will not decrease due to gravity and attract to the magnet seat 51. The sum of the magnetic force generated by the magnet block 5 and the magnet seat 51 and the gravity of the magnet block 5 is greater than the elastic force of the spring 312, so that the magnet block 5 and the magnet seat 51 can fix the car roof 6 after attraction.

[0027] Further, the distance between the magnet block 5 and the magnet seat 51 is equal to the compression length of the spring 312.

[0028] The distance between the magnet block 5 and the magnet seat 51 is equal to the compression length of the spring 312, so that after the car roof 6 pushes the baffle, the magnet block 5 and the magnet seat 51 will contact and attract each other, thus fixing the car roof 6.

[0029] Further, the distance between the slider 31 and the pulley frame 4 during operation is less than the distance between the slider 31 and the pulley frame 4 when it is idle.

[0030] When the slider 31 is working, the distance between the slider 31 and the pulley frame 4 is less than the distance between the slider 31 and the pulley frame 4 when the slider 31 is idle. When the slider 31 is idle, the traction line 313 is pulled, thereby driving the magnet block 5 to separate the magnet block 5 from the magnet seat 51.

[0031] The specific implementation is as follows: Refer to Figure 3 , move the slider 31 to the detection position. After the conveyor belt 11 transports the car roof 6 to the designated position, the baffle 311 is pushed, the spring 312 is compressed, and the traction line 313 bypassing the pulley 41 extends downward so that the magnet block 5 and the magnet seat 51 contact and attract each other, thereby fixing the car roof 6. Then, the ultrasonic knife 2 is used for processing.

[0032] Refer to Figure 4 , after the processing is completed, the slider 31 moves to the outside and pulls the traction line 313 to separate the magnet block 5 from the magnet seat 51, thereby releasing the car roof 6.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
