[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figures 1 to 3The utility model provides an embodiment: a material plate clamping structure, including a guide part 1, a transmission rod 2, a fixed tube 3 and a sleeve 4, the top of the fixed tube 3 is provided with an external thread 31, the external thread 31 is used to connect the transmission equipment, the transmission equipment drives the clamping structure to realize position transmission, the fixed tube 3 is also provided with a flat milling surface 32, the guide part 1 is provided with a guide hole 11 adapted to the flat milling surface 32, the top of the fixed tube 3 is inserted into the guide hole 11, and the flat milling surface 32 conflicts with the inner wall of the guide hole 11 to achieve a clamping effect, in this embodiment, the flat milling surface 32 is arranged at the lower end of the external thread 31, and The flat milled surface 32 extends to the external thread 31. This structure allows the fixed tube 3 to be inserted into the guide hole 11 from bottom to top, preventing the external thread 31 from blocking the insertion of the fixed tube 3, so that the flat milled surface 32 and the guide hole 11 can achieve a limiting effect. At the same time, a mounting hole 12 is provided on the guide part 1, and the locking screw is passed through the mounting hole 12 to be fixedly installed with the transmission equipment. The guide part 1 is fixedly installed at the bottom of the transmission equipment, and then the flat milled surface 32 and the guide hole 11 cooperate to prevent the clamping part 33 connected to the bottom of the fixed tube from rotating, thereby improving the clamping accuracy and preventing the clamp from scratching the board surface or failing to clamp the sheet.

[0019] Furthermore, the flat milled surface 32 can be set at the upper end of the external thread 31. The flat milled surface 32 does not need to extend to the external thread 31. The guide part 1 is fixedly installed on the upper part of the transmission equipment. After the fixed tube 3 is threadedly connected to the transmission equipment through the external thread 31 and passes through the transmission equipment, the flat milled surface 32 cooperates with the guide hole 11 to achieve precise guiding.

[0020] The transmission rod 2 is inserted into the fixed tube 3, and the sleeve 4 is sleeved on the outer side of the circumference of the fixed tube 3. The transmission rod 2 passes through both sides of the fixed tube 3 and is fixedly connected with the sleeve 4. A symmetrically arranged fixing portion 21 is provided at the bottom of the transmission rod 2. Two strip holes 34 are provided on the fixed tube 3. The two fixing portions 21 pass through the two strip holes 34 respectively and are fixedly connected with the top of the sleeve 4. Two clamping portions 33 are movably connected at the bottom of the fixed tube 3. The two clamping portions 33 form a clamping mechanism. A latch 41 is provided at the bottom of the sleeve 4. The latch 41 is located in the gap between the two clamping portions 33. The gap between the two clamping portions 33 is a cone shape that gradually decreases from bottom to top, and the upper half of the two clamping portions 33 is located in the sleeve 4. The fixed tube 3 forms a fixed end by connecting the transmission device. When the transmission rod 2 is driven upward by the driving device, the sleeve 4 and the latch 41 set in the sleeve 4 are driven at the same time. The sleeve 4 is away from the two clamping portions 33. The latch 41 moves upward and pushes the two clamping portions 33 to both sides at the same time, realizing the expansion action of the clamping structure.

[0021] It also includes a spring 5, which is sleeved on the outer side of the circumference of the fixed tube 3, and the two ends of the spring 5 are respectively in conflict with the bottom surface of the guide part 1 and the top surface of the sleeve 4. When the transmission rod 2 cancels the upward pulling force of the driving device, the sleeve 4 is driven downward by the elastic force of the spring 5 to achieve resetting. The pin 41 moves downward and resets to the bottom of the gap between the two clamping parts 33. The inner wall of the bottom of the sleeve 4 is in conflict with the outer end surfaces of the two clamping parts 33, and is pushed back to the inside to achieve the contraction clamping action of the clamping structure.

[0022] By cooperating with the clamping structure and the transmission equipment, the transmission speed of the material plate can be further increased, thereby improving production efficiency.

[0023] A locking portion 22 is provided at the top of the transmission rod 2. The locking portion 22 is used to contact with the driving device and realize tension transmission through the contact surface to pull the transmission rod 2 upward.

[0024] The inner side of the bottom of the clamping portion 33 is a clamping surface 35, on which a wavy linear protrusion is provided. The wavy linear protrusion can be embedded in a part of the material plate to achieve an anti-slip effect, improve the connection stability between the clamping structure and the material plate, and prevent it from falling during the transmission process. The bottom of the clamping portion 33 extends to both sides and can be configured to increase the area of ​​the clamping surface 35 to further improve the anti-slip effect of clamping.

[0025] The material plate is provided with an extension portion for the clamping portion 33 to clamp and abut against, and the extension portion is not used as raw material for product processing.

[0026] The bottom of the sleeve 4 is provided with an avoidance groove 42 matched with the clamping part. The avoidance groove 42 can make the expansion range of the two clamping parts 33 larger, so as to facilitate the clamping of materials.

[0027] In this embodiment, the outer end surface of the clamping portion 33 is gradually inclined outward from top to bottom. This arrangement can prevent high pressure resistance from being generated between the sleeve 4 and the clamping portion 33 when performing expansion or contraction clamping actions, thereby causing damage to the clamping structure and reducing the service life.

[0028] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
