[0010] According to the above technical solution, a rectangular groove is provided on the circumferential surface of the convex rod, and a second arc surface is provided on the bottom of the limiting plate. The second arc surface of the limiting plate contacts the inner wall of the rectangular groove during movement, so that the limiting plate applies a limit to the convex rod, and a circular groove is provided on the surface of the mounting frame.

[0011] According to the above technical solution, a No. 1 volute spring is arranged between the T-shaped rod and the limit plate.

[0014] The present invention provides a mechanical clamping device for mechanical production, which has the following beneficial effects: (1) The mechanical clamping device used in the mechanical production, the fixed plate provides the necessary support force for the slide rod through the slide groove, and the fixed plate provides the necessary support force for the sliding plate, so that when the operator pushes the plate in the safe area, the plate will not shake or shift, thereby improving the safety of plate transportation. At the same time, the downward pressure rod affected by the reaction force exerts downward pressure on the plate, and the plate in transportation is automatically clamped by the downward pressure rod, which improves the continuous operation efficiency while ensuring the stability of the plate during the cutting process, thereby ensuring the accuracy of laser cutting.

[0015] (2) The mechanical clamping device used in the mechanical production has a limit plate that contacts the inner wall of the rectangular groove during movement, so that the limit plate applies a limit to the convex rod.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 9 One embodiment of the present invention is: a mechanical clamping device for mechanical production, including a processing table 1, a linear drive device 2 is fixedly installed on the top of the processing table 1, an adjustment device 3 is arranged on the output end of the linear drive device 2, and a laser cutting machine 4 is arranged on the output end of the adjustment device 3, and also includes a fixing device; wherein the fixing device includes a fixing plate 5, a sliding plate 6, a connecting frame 7, a lower pressure rod 8, a No. 1 spring 9, a lifting plate 10 and two trapezoidal plates 11, the fixing plate 5 is fixedly installed on a side of the processing table 1 close to the laser cutting machine 4, and the sliding plate 6 is slidably installed on the inner wall of the fixing plate 5 At the bottom, the connecting frame 7 is fixedly installed on the top of the fixed plate 5, the pressing rod 8 slides through the top of the connecting frame 7, the No. 1 spring 9 is arranged between the pressing rod 8 and the connecting frame 7, the lifting plate 10 slides through the top of the sliding plate 6, and the two trapezoidal plates 11 are fixedly installed on the side of the fixed plate 5 close to the sliding plate 6. A sliding rod is fixedly installed on the surface of the sliding plate 6, and a sliding groove is provided on the side of the fixed plate 5 close to the sliding rod. The sliding rod contacts the inner wall of the sliding groove, and the plate being transported is automatically clamped by the pressing rod 8 to ensure the stability of the plate during the cutting process, thereby ensuring the accuracy of laser cutting.

[0021] The bottom of the lifting plate 10 is provided with an arc surface 1, which contacts the bottom of the inner wall of the fixed plate 5. The top of the lifting plate 10 is fixedly installed with supporting teeth. By providing the arc surface 1, it is ensured that the lifting plate 10 can move upward smoothly when it contacts the trapezoidal plate 11.

[0022] A cylindrical rod 12 is fixedly installed on one side of the connecting frame 7 close to the sliding rod. The top of the sliding plate 6 is in contact with the lifting plate 10. The fixed plate 5 provides necessary support for the sliding plate 6, so that the plate will not shake or deviate when the operator pushes the plate in a safe area.

[0023] When this embodiment is working, the plate to be cut is placed on the top of the lifting plate 10 so that the plate contacts the supporting teeth on the top of the lifting plate 10, and the supporting teeth apply an upward supporting force to the plate. Then the sliding plate 6 is manually pushed to move in the direction of the laser cutting machine 4. The movement of the sliding plate 6 drives the connecting frame 7 to move in the direction of the laser cutting machine 4. The movement of the connecting frame 7 drives the cylindrical rod 12 to move in the direction of the laser cutting machine 4, and the movement of the sliding plate 6 drives the sliding rod to move together. When the sliding rod moves, the fixed plate 5 provides the necessary supporting force for the sliding rod through the sliding groove to ensure that the sliding plate 6 remains stable during movement. At the same time, the movement of the sliding plate 6 drives the lifting plate 10 to move in the direction of the laser cutting machine 4. The movement of the lifting plate 10 drives the plate to move in the direction of the laser cutting machine 4. The necessary supporting force is provided for the sliding plate 6 through the fixed plate 5, so that when the operator pushes the plate in a safe area, the plate will not shake or deviate, thereby improving the conveying of the plate. The safety of the lifting plate 10 is ensured by the arc surface 11 of the lifting plate 10 being in contact with the inclined surface of the trapezoidal plate 11 during movement. The trapezoidal plate 11 applies resistance to the moving lifting plate 10, prompting the lifting plate 10 to move upward under the guidance of the inclined surface of the trapezoidal plate 11. The movement of the lifting plate 10 drives the plate to move upward. The top of the plate contacts the bottom of the down-pressing rod 8 during the movement, so that the movement of the plate drives the down-pressing rod 8 to move upward. The down-pressing rod 8 squeezes the No. 1 spring 9 during the movement. The No. 1 spring 9 applies a reaction force to the down-pressing rod 8 during the deformation process. The down-pressing rod 8 affected by the reaction force applies downward pressure on the plate, thereby effectively clamping the plate on the top of the lifting plate 10, and then starting the laser cutting machine 4. The laser cutting machine 4 performs laser cutting operation on the plate. The down-pressing rod 8 automatically clamps the plate in transit, which improves the continuous operation efficiency while ensuring the stability of the plate during the cutting process, thereby ensuring the accuracy of laser cutting.

[0024] See also Figure 1-Figure 9On the basis of the above embodiment, in another embodiment of the present invention, an auxiliary device for assisting the sliding plate 6 in resetting is provided on the processing table 1, and a protective device for improving the resetting safety is provided on the auxiliary device; the auxiliary device includes a mounting frame 131, a convex rod 132, a second spring 133, a connecting plate 134, an elastic rod 135, a limit plate 136, a T-shaped rod 137 and a limiting plate 138, the mounting frame 131 is fixedly mounted on the bottom of the inner wall of the processing table 1, the convex rod 132 slides through the inner and outer walls of the mounting frame 131, and the second spring 133 is arranged between the convex rod 132 and the mounting frame 131 The connecting plate 134 is fixedly mounted on a side of the convex rod 132 close to the fixed plate 5, the elastic rod 135 is fixedly mounted on the circumferential surface of the convex rod 132, the limiting plate 136 slides through the top of the mounting frame 131, the T-shaped rod 137 is rotatably mounted on the top of the limiting plate 136, and the limiting plate 138 is fixedly mounted on the top of the mounting frame 131. A circular hole is opened on a side of the connecting plate 134 close to the cylindrical rod 12, and the circular hole contacts the circumferential surface of the cylindrical rod 12. After the cutting is completed, the connecting plate 134 pulls the sliding plate 6 to move the cut plate out of the working area, which helps to improve the overall work efficiency.

[0025] A rectangular groove is provided on the circumferential surface of the convex rod 132, an arc surface 2 is provided on the bottom of the limiting plate 136, and a circular groove is provided on the surface of the mounting frame 131. By limiting the convex rod 132 moved to the specified position, the sliding plate 6 cannot move during the laser cutting process, thereby helping to improve the stability of the laser cutting.

[0026] A No. 1 volute spring is provided between the T-shaped rod 137 and the limiting plate 136. The circumferential surface of the T-shaped rod 137 contacts the top of the limiting plate 138. The No. 1 volute spring ensures that the T-shaped rod 137 will not move downward due to accidental contact.

[0027] The protective device includes a hollow frame 141, a sliding rod 142, a pulling plate 143, a spring piece 144, a rotating shaft 145, a rotating plate 146 and a rectangular plate 147. The hollow frame 141 is slidably installed on a side of the mounting frame 131 close to the circular groove, the sliding rod 142 slides through the surface of the hollow frame 141, the pulling plate 143 is fixedly installed on the top of the sliding rod 142, the spring piece 144 is arranged between the pulling plate 143 and the hollow frame 141, the rotating shaft 145 is rotatably installed on the inner wall of the hollow frame 141, the rotating plate 146 is fixedly installed on the circumferential surface of the rotating shaft 145, the rectangular plate 147 is fixedly installed on the inner wall of the hollow frame 141, the circumferential surface of the sliding rod 142 contacts the inner wall of the circular groove, and the position of the hollow frame 141 can be quickly changed through standardized operations, so that the operator can decide whether to enable the rotating plate 146 according to actual needs, thereby improving the applicability of the rotating plate 146.

[0028] A No. 2 spiral spring is arranged between the rotating shaft 145 and the hollow frame 141. The rectangular plate 147 contacts the side of the rotating plate 146 away from the sliding rod 142. The rotating plate 146 applies appropriate resistance to the elastic rod 135 that moves in the reset direction, effectively preventing the sliding plate 6 from moving too fast and ensuring that the plate can be moved out smoothly.

[0029] When the present embodiment is working, the connecting frame 7 drives the connecting plate 134 to move toward the direction of the laser cutting machine 4 through the cylindrical rod 12, and the movement of the connecting plate 134 drives the convex rod 132 to move toward the direction of the laser cutting machine 4, and the movement of the convex rod 132 drives the elastic rod 135 to move toward the direction of the laser cutting machine 4. At the same time, the convex rod 132 squeezes the No. 2 spring 133 during the movement, and the No. 2 spring 133 is squeezed and deformed. When the elastic rod 135 contacts the inner wall of the carrying frame 131, the operator controls the sliding plate 6 with one hand and rotates the T-shaped rod 137 with the other hand. The T-shaped rod 137 rotates during the rotation process. The first scroll spring is stretched and deformed by the stretching. At the same time, the contact surface of the T-shaped rod 137 and the limiting plate 138 are separated, so that the restriction on the downward movement of the T-shaped rod 137 is released. The operator then controls the T-shaped rod 137 to move downward. The movement of the T-shaped rod 137 drives the limiting plate 136 to move downward. The arc surface 2 of the limiting plate 136 contacts the inner wall of the rectangular groove during the movement, so that the limiting plate 136 applies a limit to the convex rod 132. The above operation is repeated to limit the convex rod 132 on the other side. By limiting the convex rod 132 moved to the specified position, the sliding plate 6 cannot move during the laser cutting process, which helps to improve the stability of laser cutting. After the cutting operation is completed, the T-shaped rod 137 is pulled upward. When the T-shaped rod 137 moves to the predetermined position, the deformed No. 1 scroll spring is restored to drive the T-shaped rod 137 to rotate to the initial position. At the same time, the movement of the T-shaped rod 137 drives the limit plate 136 to move upward, and the limit plate 136 moves and separates from the rectangular groove. The limit of the convex rod 132 is released, so that the deformed No. 2 spring 133 is restored to drive the convex rod 132 to move away from the laser cutting machine 4. The movement of the convex rod 132 drives the elastic rod 135 moves in the direction away from the laser cutting machine 4, and at the same time, the convex rod 132 moves to drive the connecting plate 134 to move in the direction away from the laser cutting machine 4, and the connecting plate 134 pulls the sliding plate 6 to move in the direction away from the laser cutting machine 4 through the cylindrical rod 12, and the sliding plate 6 moves to drive the lifting plate 10 to move in the direction away from the laser cutting machine 4, and the lifting plate 10 moves to drive the plate to move in the direction away from the laser cutting machine 4. After the cutting is completed, the connecting plate 134 pulls the sliding plate 6 to move the cut plate out of the working area, which helps to save the physical burden of the operator and improve the overall work efficiency; When the elastic rod 135 moves toward the direction of the laser cutting machine 4, the elastic rod 135 contacts with a side of the rotating plate 146 away from the sliding rod 142 during the movement. The movement of the elastic rod 135 drives the rotating plate 146 to rotate toward the sliding rod 142. The surface of the rotating plate 146 that contacts the rectangular plate 147 during the rotation is separated. At the same time, the rotation of the rotating plate 146 drives the rotating shaft 145 to rotate toward the sliding rod 142. The rotating shaft 145 stretches the No. 2 scroll spring during the rotation. The No. 2 scroll spring is deformed by the stretching. When the elastic rod 135 separates from the rotating plate 146, the deformed No. 2 scroll spring drives the rotating shaft 145 to reset. The rotation of the rotating shaft 145 drives the rotating plate 146 to reset. When the elastic rod 135 moves in the direction away from the laser cutting machine 4, the elastic rod 135 contacts with the side of the rotating plate 146 close to the sliding rod 142 during the movement. The rotating plate 146 applies resistance to the moving elastic rod 135, and the elastic rod 135 continues to move and deforms. At the same time, the movement speed of the elastic rod 135 is slowed down by the influence of the additional resistance. When the elastic rod 135 is separated from the rotating plate 146, the deformed elastic rod 135 quickly recovers, and the rotating plate 146 applies appropriate resistance to the elastic rod 135 that is resetting and moving, which effectively prevents the sliding plate 6 from moving too fast, ensuring that the plate can be smoothly removed. When the rotating plate 146 is not needed, the pull is manually controlled. The movable plate 143 moves upward, and the pulling plate 143 stretches the spring sheet 144 during the movement. The spring sheet 144 is deformed by the stretching, and at the same time, the pulling plate 143 moves to drive the sliding rod 142 to move upward. The sliding rod 142 separates from the circular groove during the movement, so that the limit imposed by the sliding rod 142 on the hollow frame 141 is released, and the pulling plate 143 is controlled to move in a direction away from the laser cutting machine 4. The movement of the pulling plate 143 drives the sliding rod 142 to move in a direction away from the laser cutting machine 4. The movement of the sliding rod 142 drives the hollow frame 141 to move in a direction away from the laser cutting machine 4. The movement of the hollow frame 141 drives the rotating shaft 145 and the rectangular plate 147 to move in a direction away from the laser cutting machine 4 The rotating shaft 145 moves and drives the rotating plate 146 to move away from the laser cutting machine 4. When the hollow frame 141 moves to the predetermined position, the pulling plate 143 is released, and the deformed spring piece 144 recovers and drives the pulling plate 143 to move downward. The movement of the pulling plate 143 drives the sliding rod 142 to move downward. The sliding rod 142 contacts the inner wall of the circular groove during the movement, so that the movement of the hollow frame 141 is limited. At the same time, the elastic rod 135 does not contact the rotating plate 146 during the movement. The position of the hollow frame 141 can be quickly changed through standard operations, so that the operator can decide whether to enable the rotating plate 146 according to actual needs, thereby improving the applicability of the rotating plate 146.
