[0021] In order to make the technical means, creative features, achieved purposes and effects of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0022] As Figure 1 、 Figure 2 shown, the utility model provides a mechanical gripper for mechanical manufacturing, including a mechanical gripper transfer mechanism 1. Mechanical workpiece conveyor belts 2 are arranged on both sides of the transfer of the mechanical gripper transfer mechanism 1. The mechanical gripper transfer mechanism 1 includes a placing base 11. A fixed vertical column 12 is fixedly installed on the top of the placing base 11. A drive box body 13 is fixedly installed on the top of the fixed vertical column 12. Two limit metal vertical plates 14 are fixedly installed on the front side of the top of the drive box body 13. A support vertical column 15 is arranged above the drive box body 13. A mechanical gripper fixed cross column 16 is fixedly installed above the right side of the support vertical column 15. An extension cross plate is fixedly installed at the right end of the mechanical gripper fixed cross column 16. An electric push rod 18 is fixedly installed on the top of the extension cross plate. The output end of the electric push rod 18 penetrates to the bottom of the extension cross plate and is fixedly installed with a mechanical gripper mechanism 19. Magnetic attraction plates 17 are fixedly installed on both the front and rear sides of the mechanical gripper fixed cross column 16. The front magnetic attraction plate 17 is adsorbed to the uppermost part of the rear side of the right limit metal vertical plate 14;

[0023] By using the connection between the steering column 132 and the support column 15, the overall mechanical gripper can be driven to fix the cross column 16 and the mechanical gripper mechanism 19 below the electric push rod 1 to rotate reciprocally 180 degrees left and right, and the mechanical gripper mechanism 19 can repeatedly move back and forth on the top of the two mechanical workpiece conveyors 2 on the left and right sides. And each time the cross column 16 fixed by the mechanical gripper rotates, the adsorption between the magnetic plates 17 on the front and rear sides and the two limit metal vertical plates 14 can be used to improve the stability, and at the same time, it does not affect the next rotation of the cross column 16 fixed by the mechanical gripper.

[0024] As Figure 3 shown, a rotating gear 131 is movably installed at the center of the bottom inner wall of the driving box 13. A steering column 132 is fixedly installed at the center of the top of the rotating gear 131. The top end of the steering column 132 penetrates through the top of the driving box 13 and is fixedly connected to the bottom of the support column 15. Brushless motors 133 are fixedly installed on both the left and right sides of the bottom of the driving box 13. The two brushless motors 133 are respectively located on the left and right sides of the fixed column 12. The top ends of the output shafts of the two brushless motors 133 penetrate into the inner cavity of the driving box 13 and are fixedly installed with half gears 134. Half of the tooth blocks on the outer walls of the two half gears 134 are meshed with the rotating gear 131, and the output shafts of the two brushless motors 133 rotate in opposite directions;

[0025] When grasping, by starting the brushless motor 133 on the right side of the bottom of the driving box 13, the half gear 134 on the right side of the inner cavity of the driving box 13 can be driven to rotate. By using the meshing of the half tooth blocks of the half gear 134 with the rotating gear 131, the steering column 132 can be driven to rotate 180 degrees until the tooth blocks of the right half gear 134 disengage from the rotating gear 131 and then stop rotating. At this time, the tooth blocks of the left half gear 134 are not meshed with the rotating gear 131. When starting the brushless motor 133 on the left side of the bottom of the driving box 13 to drive the half gear 134 on the left side of the inner cavity of the driving box 13 to rotate in the opposite direction, the rotating gear 131 and the steering column 132 can be driven to rotate reversely 180 degrees by using the meshing of the half tooth blocks of the left half gear 134 with the rotating gear 131.

[0026] As Figure 4 、 Figure 5As shown in the figure, the mechanical gripper mechanism 19 includes a fixed suspension plate 191, which is fixedly connected to the bottom of the output end of the first electric push rod 18. A loading and clamping box 192 is movably installed on the front side of the bottom of the fixed suspension plate 191. A rotating motor 193 is fixedly installed on the right side of the fixed suspension plate 191. The output shaft of the rotating motor 193 is fixedly installed with a clamping and sealing plate 194. After the clamping and sealing plate 194 rotates 90 degrees, it seals the front side of the loading and clamping box 192. An electric push rod 1911 is fixedly installed on the top right side of the fixed suspension plate 191. The output end of the electric push rod 1911 is movably installed with an L-shaped telescopic rod 1912. An L-shaped telescopic rod 1913 is slidably connected to the inner cavity of the vertical part of the L-shaped telescopic rod 1912. The rear end of the horizontal part of the L-shaped telescopic rod 1913 is fixedly connected to the rear side of the loading and clamping box 192;

[0027] When the mechanical gripper mechanism 19 is above the right mechanical workpiece conveyor belt 2, the clamping and sealing plate 194 is in a horizontal state. By starting the first electric push rod 18 to drive the loading and clamping box 192 to move downward until the bottom of the loading and clamping box 192 touches the top of the right mechanical workpiece conveyor belt 2 and stops, the small mechanical manufacturing workpieces on the mechanical workpiece conveyor belt 2 can enter the loading and clamping box 192. Then, by starting the rotating motor 193 to drive the clamping and sealing plate 194 to rotate counterclockwise by 90 degrees, the workpiece can be pushed into the inner cavity of the loading and clamping box 192 while sealing the rear side of the loading and clamping box 192. Then, by starting the first electric push rod 18 to raise the fixed suspension plate 191 and starting the brushless motor 133 to drive the support column 15 to rotate above the left mechanical workpiece conveyor belt 2. At this time, start the first electric push rod 18 to drive the fixed suspension plate 191 to descend, and start the electric push rod 1911 on the top of the fixed suspension plate 191, which can drive the L-shaped telescopic rod 1912 movably installed at the output end to move backward while rotating, and extend the vertical part of the L-shaped telescopic rod 1913, and rotate the loading and clamping box 192 counterclockwise by a certain angle, so that the workpiece inside it can fall onto the left mechanical workpiece conveyor belt 2 under the action of gravity for transportation, completing the transfer.

[0028] Next, the working principle of the mechanical gripper for mechanical manufacturing will be specifically described.

[0029] As Figures 1 - 5As shown in the figure, when grasping, the brushless motor 133 on the right side of the bottom of the driving box body 13 is started, so as to drive the half gear 134 on the right side of the inner cavity of the driving box body 13 to rotate. By using the engagement of the half tooth blocks of the half gear 134 with the rotating gear 131, the steering column 132 can be driven to rotate 180 degrees until the tooth blocks of the right half gear 134 disengage from the rotating gear 131 and stop rotating. At this time, the tooth blocks of the left half gear 134 do not engage with the rotating gear 131. When the brushless motor 133 on the left side of the bottom of the driving box body 13 is started to drive the half gear 134 on the left side of the inner cavity of the driving box body 13 to rotate in the opposite direction, the rotating gear 131 and the steering column 132 can be driven to rotate reversely 180 degrees by using the engagement of the half tooth blocks of the left half gear 134 with the rotating gear 131. By using the connection between the steering column 132 and the support column 15, the overall mechanical claw can be driven to fix the cross column 16 and the mechanical claw mechanism 19 below the first electric push rod 18 to rotate 180 degrees left and right reciprocally, and the mechanical claw mechanism 19 can be made to move back and forth on the top of the two mechanical workpiece conveyor belts 2 on the left and right sides repeatedly. And each time the mechanical claw fixing cross column 16 rotates, the adsorption between the magnetic attraction plates 17 on the front and rear sides and the two limiting metal vertical plates 14 can be used to improve the stability, and at the same time, it does not affect the next rotation of the mechanical claw fixing cross column 16. When the mechanical claw mechanism 19 is located above the right mechanical workpiece conveyor belt 2, the clamping sealing plate 194 is in a horizontal state. By starting the first electric push rod 18 to drive the loading and clamping box 192 to move downward until the bottom of the loading and clamping box 192 contacts the top of the right mechanical workpiece conveyor belt 2 and stops, the small mechanical manufacturing workpieces on the mechanical workpiece conveyor belt 2 can enter the loading and clamping box 192. Then, by starting the rotating motor 193 to drive the clamping sealing plate 194 to rotate counterclockwise by ninety degrees, the workpiece can be pushed and clamped into the inner cavity of the loading and clamping box 192 while sealing the rear side of the loading and clamping box 192. Then, by starting the first electric push rod 18 to raise the fixed hanging plate 191 and starting the brushless motor 133 to drive the support column 15 to rotate above the left mechanical workpiece conveyor belt 2. At this time, start the first electric push rod 18 to drive the fixed hanging plate 191 to descend, and start the second electric push rod 1911 on the top of the fixed hanging plate 191, which can drive the L-shaped telescopic rod 1912 with the output end movably installed to move backward while rotating, so that the vertical part of the L-shaped telescopic rod 1913 can be extended, and the loading and clamping box 192 can be rotated counterclockwise by a certain angle, so that the workpiece inside it can fall onto the left mechanical workpiece conveyor belt 2 under the action of gravity for transportation, and the transfer is completed.

[0030] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
