[0022] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] Figure 1-3 One embodiment of the utility model is a rubber gasket cutting and positioning device, comprising a cutting table 1, with support vertical plates 2 perpendicular to the cutting table 1 provided on both sides of the cutting table 1, a cutting knife assembly 3 for cutting the rubber gasket on the cutting table 1 provided above the support vertical plates 2, and a positioning assembly 4 for positioning the rubber gasket above the cutting table 1 provided on the side wall of the support vertical plates 2 facing the cutting table 1. In actual work, the rubber gasket to be cut is laid flat on the cutting table 1, and the cutting knife assembly 3 is automatically moved by a set program to perform a preset cutting on the rubber gasket on the cutting table 1, so as to obtain a gasket of a required size;

[0024] The positioning assembly 4 includes a slot plate 41 located on both sides of the cutting table 1. The slot plate 41 is hollow inside and has a sliding slot 42 parallel to the cutting table 1 surface on the side wall facing the cutting table 1. A pressure rod 43 parallel to the cutting table 1 surface is provided above the cutting table 1 surface. Both ends of the pressure rod 43 pass through the sliding slot 42 and are inserted into the slot plate 41. Both ends of the pressure rod 43 located in the slot plate 41 are provided with elastic pressure rods 44 for pressing the pressure rod 43 down to contact the rubber gasket placed above the cutting table 1 surface. In actual work, when the cutting knife group When the component 3 contacts the rubber gasket for cutting, in order to prevent the rubber gasket from shifting, the staff manually adjusts the pressure rod 43 to move the pressure rod 43 along the range of the sliding groove 42, and makes the pressure rod 43 abut against the surface edge of the rubber gasket according to the size of the cut rubber gasket. Since the elastic pressure rod 44 applies downward pressure to the pressure rod 43, the pressure rod 43 can be pressed against the surface edge of the rubber gasket with force, so that the position of the rubber gasket on the cutting table 1 is fixed, preventing the rubber gasket from being skewed during the cutting work.

[0025] The sliding groove 42 includes a long groove 421 horizontal to the surface of the cutting table 1, and the bottom edge of the long groove 421 is provided with a plurality of vertical grooves 422 perpendicular to the long groove 421; the elastic pressure rod 44 includes a horizontal plate 441 fixedly connected to the outer side of the two ends of the pressure rod 43, and the top surface of the horizontal plate 441 is provided with a vertical rod 442 extending vertically upward, and the top of the vertical rod 442 extends to the outer side of the top surface of the groove plate 41, and the outer side of the vertical rod 442 located in the groove plate 41 is sleeved with a spring 443 for pressing the horizontal plate 441 downward. In actual work, when the pressure rod 43 abuts against the surface of the rubber gasket to press the rubber gasket, the pressure rod 43 is pushed and clamped in the vertical groove 422 by the elastic pressure rod 44, so that the position of the pressure rod 43 is limited. When the position of the pressure rod 43 is adjusted according to the size of the rubber gasket, the staff manually pulls the pressure rod 43 upward to make the pressure rod 43 away from the cutting table 1 surface. At this time, the horizontal plate 441 rises with the rise of the pressure rod 43, thereby pressing the spring 443 to contract. When the pressure rod 43 moves into the long groove 421, the pressure rod 43 can be moved above the cutting table 1 along the direction of the long groove 421. When the pressure rod 43 moves to the required position, the staff releases the pressure rod 43. Due to the elastic force of the spring 443, the horizontal plate 441 and the pressure rod 43 are pushed toward the cutting table 1 surface, so that the pressure rod 43 is clamped in the corresponding vertical groove 422. The pressure rod 43 is pressed on the rubber gasket on the cutting table 1 surface to achieve fixed limiting of the rubber gasket.

[0026] There are no less than two groups of pressure rods 43 to achieve the pressing of the front and rear edges of the rubber gasket. The pressure rods 43 are arranged parallel to each other. The end of the pressure rod 43 is provided with a first limit plate 431 fixedly connected to the side wall of the horizontal plate 441, and the pressure rod 43 located on the outside of the sliding groove 42 is provided with a second limit plate 432 for preventing the pressure rod 43 from being dislocated. In actual work, the first limit plate 431 and the second limit plate 432 are respectively clamped on the inner and outer side walls of the sliding groove 42 to limit the pressure rod 43. At the same time, the area of ​​the first limit plate 431 and the second limit plate 432 is larger than the diameter of the sliding groove 42 to avoid the first limit plate 431 and the second limit plate 432 from being dislocated when the pressure rod 43 is adjusted, thereby ensuring the stability of the adjustment of the pressure rod 43.

[0027] The top wall of the slot plate 41 is provided with a through slot 411 for the vertical rod 442 to pass through when moving. The width of the through slot 411 is greater than the diameter of the vertical rod 442, and the length of the through slot 411 matches the length of the sliding slot 42. In actual work, when the adjustment pressure rod 43 moves along the range of the long slot 421, the vertical rod 442 moves along the range of the through slot 411, which ensures the stability of the pressure rod 43 while limiting the pressure rod 43 and the elastic pressure rod 44.

[0028] The top end of the vertical rod 442 is inserted into the through groove 411 and extends upward to the outer side of the top wall of the slot plate 41. A fixing plate 444 is provided at the end of the vertical rod 442 located on the outer side of the top wall of the slot plate 41. In actual work, when the pressure rod 43 is adjusted and the pressure rod 43 is pulled into the long groove 421, the fixing plate 444 and the end of the vertical rod 442 rise. When the pressure rod 43 is clamped in the vertical groove 422 due to the pressure of the spring 443, the bottom surface of the fixing plate 444 abuts against the outer side of the top wall of the slot plate 41, thereby limiting the height of the vertical rod 442 and ensuring the position of the spring 443 at the same time, thereby improving the overall service life of the elastic pressure rod 44.

[0029] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
