DETAILED DESCRIPTION
[0021] The following is combined with Figure 1-5 This application is described in further detail.
[0022] The present application embodiment discloses a mechanical gripper of a mechanical device, referring to Figure 1 , Figure 2 , Figure 4 and Figure 5, including a U-shaped seat 1, one of the flange outer walls of the U-shaped seat 1 is fixedly connected to a servo motor 2, the output end of the servo motor 2 passes through the flange side wall of the U-shaped seat 1 and is fixedly connected to a screw rod 3, the external thread of the screw rod 3 is connected to an adjusting block 5, the bottom of the adjusting block 5 is fixedly connected to a hydraulic cylinder 6, the output end of the hydraulic cylinder 6 is fixedly connected to a U-shaped frame 7, the inner wall of the web of the U-shaped frame 7 is fixedly connected to a forward and reverse motor 8, the output end of the forward and reverse motor 8 is fixedly connected to a worm 9, the outside of the worm 9 is symmetrically meshed with two worm wheels 10, the inside of the worm wheel 10 is fixedly connected to a connecting shaft 11, the outside of the connecting shaft 11 and on both sides of the worm wheel 10 are fixedly connected to transmission plates 12, the ends of the two transmission plates 12 away from the worm wheel 10 are hingedly provided with clamping plates 13, when When it is necessary to clamp and grasp the workpiece, the servo motor 2 is started, and the servo motor 2 drives the screw 3 to work, thereby driving the adjusting block 5 to move linearly on the screw 3. The top of the adjusting block 5 should be tightly fitted with the inner wall of the belly plate of the U-shaped seat 1 to avoid the adjustment block 5 from being offset when it moves outside the screw 3, so as to achieve real-time adjustment of the position of the mechanical clamp. The hydraulic cylinder 6 is started to drive the clamping plate 13 to move to both sides of the workpiece to be clamped, and the forward and reverse motors 8 are started. The forward and reverse motors 8 work to drive the worm 9 to work, and the worm 9 works to drive the two worm wheels 10 outside it to rotate, and the rotation of the worm wheel 10 drives the transmission plate 12 to rotate together. Under the action of the limit plate 15 and the transmission plate 12, the two clamping plates 13 will approach or move away from each other.
[0023] Reference Figure 3 and Figure 5 A fixing rod 14 is fixedly connected to the inner wall of one of the flanges of the U-shaped frame 7 and located on both sides of the worm 9. Two limit plates 15 are hingedly arranged on the outside of the fixing rod 14. The ends of the two limit plates 15 away from the fixing rod 14 are hingedly arranged with the clamping plate 13. When the worm gear 10 rotates, the connecting shaft 11 also rotates. Under the action of the limit plate 15 and the transmission plate 12, the two clamping plates 13 will approach or move away from each other, thereby realizing the fixation and gripping of workpieces of different sizes.
[0024] Reference Figure 3 , Figure 4 and Figure 5 A plurality of rows of arc-shaped protrusions 16 are provided on the sides of the two clamping plates 13 that are close to each other. The arc-shaped protrusions 16 can increase the friction between the clamping plates 13 and the workpiece, thereby increasing the clamping force of the clamping plates 13 on the workpiece.
[0025] Reference Figure 3 and Figure 5 One end of the connecting shaft 11 is rotatably connected to the inner wall of the U-shaped seat 1.
[0026] Reference Figure 1 and Figure 2A connecting plate 4 is fixedly installed on the outer wall of the web of the U-shaped seat 1. Two connecting holes 17 are provided inside the connecting plate 4. By setting bolts through the connecting holes 17, the position of the entire device can be fixed.
[0027] The implementation principle of the mechanical clamp of a mechanical device in the embodiment of the present application is as follows: by setting bolts through the inside of the connecting hole 17, the position of the entire device can be fixed. When the workpiece needs to be clamped and grasped, the servo motor 2 is started, and the servo motor 2 drives the screw rod 3 to work, thereby driving the adjustment block 5 to move linearly on the screw rod 3. The top of the adjustment block 5 should be tightly fitted with the inner wall of the belly plate of the U-shaped seat 1 to avoid the adjustment block 5 from being offset when it moves outside the screw rod 3, so that the real-time adjustment of the position of the mechanical clamp can be achieved. The hydraulic cylinder 6 is started to drive the clamping plate 13 to move to both sides of the workpiece to be clamped. Figure 4 As shown, the front side of the adjusting block 5 is fixedly connected with a limit rod, and the limit rod is slidably connected to the front side of the U-shaped frame 7, so as to prevent the hydraulic cylinder 6 from driving the U-shaped frame 7 to lift and lower and cause rotational deviation. An anti-drop cap can be provided at the bottom of the limit rod to prevent the U-shaped frame 7 from detaching from the limit rod during the sliding process. The forward and reverse motors 8 are started, and the forward and reverse motors 8 drive the worm 9 to work. The worm 9 drives the two worm wheels 10 outside it to rotate, and the rotation of the worm wheel 10 drives the transmission plate 12 to rotate together. At this time, the limit plate 15 will also drive the clamping plate 13 to rotate around the fixed rod 14. Under the action of the limit plate 15 and the transmission plate 12, the two clamping plates 13 will approach or move away from each other, thereby realizing the fixation and grasping of workpieces of different sizes. The friction between the clamping plate 13 and the workpiece can be increased by the arc-shaped protrusion 16, thereby increasing the clamping force of the clamping plate 13 on the workpiece.
