Technical Field

[0001] This utility model belongs to the technical field of cutting machine accessories, specifically relating to a positioning component for fixed-length cutting on a cutting machine. Background Technology

[0002] Cutting machines are indispensable punching and cutting equipment in light industry. They are mainly used to precisely cut materials using die-cutting molds. During the use of cutting machines, positioning components are usually required to cut materials to a fixed length.

[0003] However, in actual use, when the positioning baffle is adjusted to the appropriate length, the material being cut is prone to impact when it comes into contact with the positioning baffle. This not only easily damages the material itself, but also causes it to spring back, resulting in the cutting length being shorter than the set value. Utility Model Content

[0004] The purpose of this invention is to provide a positioning component for fixed-length cutting on a cutting machine, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning component for fixed-length cutting on a cutting machine, comprising a positioning frame and a cutting machine, wherein the positioning frame is bolted to one end of the cutting machine via a mounting plate at one end, and scale plates are provided on both sides of the mounting plate, and a movable baffle is slidably connected to the top of the positioning frame, wherein a buffer structure for reducing the impact force of materials is provided on the side of the movable baffle facing the cutting machine, and self-locking structures for self-locking are provided on both sides of the movable baffle.

[0006] In a preferred embodiment, the movable baffle is inverted "L" shape, and the buffer structure includes an auxiliary frame rotatably connected to the top of the inner cavity of the movable baffle facing the cutting machine. A bottom roller is rotatably connected to the bottom of the auxiliary frame, and the bottom roller contacts the top of the positioning frame.

[0007] In a preferred embodiment, guide grooves are provided on both sides of the movable baffle facing the auxiliary frame. A guide post is fixedly connected inside the guide groove, and a sliding block is slidably connected outside the guide post. A reset spring sleeved on the outside of the guide post is fixedly connected between the top of the sliding block and the top of the inner cavity of the guide groove.

[0008] In a preferred embodiment, the auxiliary frame is rotatably connected to a connecting plate on the side facing the two guide slots, and the other end of the two connecting plates is rotatably connected to the front of the two sliding blocks respectively.

[0009] In a preferred embodiment, the self-locking structure includes side posts fixedly connected to both sides of the movable baffle, a stop plate rotatably connected to the outside of the side posts, and a torsion spring sleeved on the outside of the side posts, with the two ends of the torsion spring abutting against the movable baffle and the stop plate respectively.

[0010] In a preferred embodiment, side plates are fixedly connected to both sides of the positioning frame directly below the abutment plate, and the top of the side plates has multiple equidistant inclined grooves that are adapted to the bottom end of the abutment plate.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Please see Figures 1-4 This utility model provides a positioning component for fixed-length cutting on a cutting machine, including a positioning frame 1 and a cutting machine. The positioning frame 1 is bolted to one end of the cutting machine via a mounting plate 102 at one end. Both sides of the positioning frame 1 are provided with scale plates 101. A movable baffle 2 is slidably connected to the top of the positioning frame 1. The side of the movable baffle 2 facing the cutting machine has a buffer structure for reducing the impact force of the material. The movable baffle 2 is inverted "L" shape. The buffer structure includes an auxiliary frame 202 rotatably connected to the top of the inner cavity of the side of the movable baffle 2 facing the cutting machine. A bottom roller 208 is rotatably connected to the bottom of the auxiliary frame 202. The roller 208 contacts the top of the positioning frame 1. The movable baffle 2 has guide grooves 203 on both sides of the side facing the auxiliary frame 202. The guide column 204 is fixedly connected inside the guide groove 203. The sliding block 206 is slidably connected to the outside of the guide column 204. The top of the sliding block 206 and the top of the inner cavity of the guide groove 203 are fixedly connected to a return spring 205 sleeved on the outside of the guide column 204. The auxiliary frame 202 is rotatably connected to the side facing the two guide grooves 203. The other end of the two connecting plates 207 is rotatably connected to the front of the two sliding blocks 206 respectively.

[0023] During the operation of the cutting machine, the material extends and moves towards the moving baffle 2. When the material comes into contact with the moving baffle 2, it will first come into contact with the bottom roller 208 of the buffer structure. Since the bottom roller 208 is rotatably connected to the bottom of the auxiliary frame 202, and the auxiliary frame 202 is rotatably connected to the top of the inner cavity of the moving baffle 2 facing the cutting machine, the bottom roller 208 will roll on the top of the positioning frame 1 under the pushing force of the material, and the auxiliary frame 202 will rotate at the same time.

[0024] When the auxiliary frame 202 rotates, it will drive the connecting plate 207, which is rotatably connected to one side of the two guide grooves 203, to move. The other end of the connecting plate 207 is rotatably connected to the front of the sliding block 206. The sliding block 206 is slidably connected to the guide post 204 inside the guide groove 203. Therefore, the connecting plate 207 will pull the sliding block 206 to slide upward along the guide post 204, compressing the return spring 205 fixedly connected between the top of the sliding block 206 and the top of the inner cavity of the guide groove 203. During the compression process, the return spring 205 will absorb the impact force of the material on the moving baffle 2, play a buffering role, and prevent the moving baffle 2 from being damaged by the direct impact force.

[0025] When the material moves into place and no longer applies a pushing force to the moving baffle 2, the compressed return spring 205 releases its elastic potential energy, pushing the sliding block 206 to slide down and reset along the guide post 204. The sliding block 206 drives the auxiliary frame 202 and the bottom roller 208 back to their initial positions through the connecting plate 207, preventing the material from rebounding due to the loss of the moving baffle 2 and ensuring the accuracy of the cutting length.

[0026] The buffer structure greatly protects the moving baffle 2 and the entire positioning assembly. When the material comes into contact with the moving baffle 2, the bottom roller 208 rolls and the auxiliary frame 202 rotates. Combined with the buffering effect of the return spring 205, the impact force of the material on the moving baffle 2 can be effectively absorbed, preventing the moving baffle 2 from being damaged due to directly bearing a large impact force. This extends the service life of the positioning assembly and reduces equipment maintenance costs. After the material moves into place, the reset function of the buffer structure can prevent the material from rebounding. This not only ensures the accuracy of the cutting length but also avoids the injury that material rebound may cause to the operator, improving the safety of equipment use.

[0027] In this embodiment, the movable baffle 2 is provided with a self-locking structure on both sides. The self-locking structure includes side posts 209 fixedly connected to both sides of the movable baffle 2. A stop plate 2010 is rotatably connected to the outside of the side posts 209. A torsion spring 2011 is sleeved on the outside of the side posts 209. The two ends of the torsion spring 2011 abut against the movable baffle 2 and the stop plate 2010 respectively. Side plates 103 are fixedly connected to both sides of the positioning frame 1 directly below the stop plate 2010. The top of the side plates 103 is provided with a plurality of inclined grooves 104 that are equally spaced and adapted to the bottom end of the stop plate 2010. A drive motor 3 is fixedly connected to one end of the positioning frame 1. A transmission screw 4 is fixedly connected to the output shaft of the drive motor 3. A threaded block 201 is threadedly connected to the outside of the transmission screw 4 at the bottom of the movable baffle 2.

[0028] The positioning frame 1 is securely mounted on one end of the cutting machine by bolts via the mounting plate 102 at one end. The operator can position the moving baffle 2 according to the actual cutting length requirements by referring to the scale plate 101.

[0029] Start the drive motor 3 fixedly connected to one end of the positioning frame 1. The output shaft of the drive motor 3 drives the transmission screw 4 to rotate. Since the bottom of the moving baffle 2 is provided with a threaded block 201 threadedly connected to the outside of the transmission screw 4, under the rotation of the transmission screw 4, the threaded block 201 will move linearly along the transmission screw 4, thereby driving the moving baffle 2 to slide on the top of the positioning frame 1, so as to achieve precise adjustment of the position of the moving baffle 2.

[0030] When the movable baffle 2 is adjusted to the appropriate position, the abutment plate 2010 of the self-locking structure is rotatably connected to both sides of the movable baffle 2 via the side column 209. The two ends of the torsion spring 2011 sleeved on the outside of the side column 209 abut against the movable baffle 2 and the abutment plate 2010 respectively. Under the elastic force of the torsion spring 2011, the abutment plate 2010 tends to rotate towards the side plates 103 on both sides of the positioning frame 1. As the movable baffle 2 moves into place, the bottom end of the abutment plate 2010 will be inserted into the inclined groove 104 opened at the top of the side plate 103 that matches the bottom end of the abutment plate 2010, thereby realizing the self-locking of the movable baffle 2 and preventing it from being displaced by external force during subsequent use.

[0031] The working principle and usage process of this utility model are as follows: First, the positioning frame 1 is securely mounted on one end of the cutting machine by a mounting plate 102 and bolts. The operator can use the scale plate 101 to position the moving baffle 2.

[0032] Start the drive motor 3 at one end of the positioning frame 1. Its output shaft drives the transmission screw 4 to rotate. Since the threaded block 201 at the bottom of the moving baffle 2 is threadedly connected to the transmission screw 4, the threaded block 201 moves linearly along the screw, causing the moving baffle 2 to slide on the top of the positioning frame 1, so as to achieve precise position adjustment.

[0033] After the movable baffle 2 is adjusted to the appropriate position, the self-locking abutment 2010 is connected to both sides of it via the side column 209. The two ends of the torsion spring 2011 abut against the movable baffle 2 and the abutment 2010, causing the abutment 2010 to have a tendency to rotate towards the side plate 103. After moving into place, the bottom end of the abutment 2010 is inserted into the inclined groove 104 of the side plate 103 to achieve self-locking and anti-displacement.

[0034] When the cutting machine is working, the material moves towards the moving baffle 2 and first contacts the bottom roller 208 of the buffer structure. The material pushes the bottom roller 208 to roll on the top of the positioning frame 1. The auxiliary frame 202 rotates, which drives the connecting plate 207 to pull the sliding block 206 to slide up along the guide column 204. The compression return spring 205 absorbs the impact force and protects the moving baffle 2.

[0035] When the material is in place without any pushing force, the reset spring 205 releases its elastic potential energy, pushing the sliding block 206 to slide down and reset. The connecting plate 207 then drives the auxiliary frame 202 and the bottom roller 208 to return to their original positions, preventing the material from springing back and ensuring accurate cutting length.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
