[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Gear transmission is adopted. Compared with connecting rod transmission and thread transmission, the transmission mechanical efficiency reaches 97-99%, with high transmission accuracy, strong load-bearing capacity, small wear, long service life and high economic benefits.

[0019] 2. The modular design features flexible jaw configurations to accommodate different materials. Two-jaw, three-jaw, four-jaw, and four-jaw staggered clamping options are available, depending on the material's contour. The jaws can be clamped synchronously for easy centering.

Simultaneously, a well-adjusted spring supports the movable jaws, maintaining a stable grip without excessive force that could damage the material.

[0022] 5. The clamping and loosening actions are easy to be automatically controlled by PLC.

When the distance between the release sensor sheet and the working end of the release sensor is appropriate, the release sensor working circuit is connected, and an electrical signal is sent to the PLC to control the stepper motor to stop.

[0024] 6. The electric clamping jaws are powered by a stepper motor. The clamping displacement stroke can be precisely adjusted and controlled. The clamping speed is adjustable and controllable. When the stepper motor stops, the electromagnetic force self-locks to prevent the motor from reversing and loosening the material. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The motor gear drive assembly includes a stepper motor 9 and a gear 1, the gear 1 is connected to the power output end of the stepper motor 9, a gear partition 2 is provided on the gear 1, the toothed belt transmission assembly is connected to the gear 1, the stepper motor 9 is connected to the bottom end of the shell, and the power output end of the stepper motor 9 passes through the guide rail assembly and is connected to a distance sleeve 11 and a dial 18, and the dial 18 is connected to the power output end of the stepper motor 9 through a dial fixing screw 19.

[0048] The guide rail assembly includes a guide rail plate 6 and an upper cover plate 8 and a lower cover plate arranged on the upper and lower sides of the guide rail plate 6. The guide rail plate 6, the upper cover plate 8 and the lower cover plate are all provided with corresponding guide grooves. The diameter of the guide rail plate 6 is smaller than the diameters of the upper cover plate 8 and the lower cover plate. The guide rail plate 6 forms an inner recess with the upper cover plate 8 and the lower cover plate. The guide rail plate 6 is fixedly connected to the shell by a guide rail plate fixing screw 7.

[0049] In this embodiment, the top slide is set as a cross-shaped slide, four guide grooves are evenly arranged on the guide rail plate 6 in the circumferential direction, and a total of four groups of movable claw head assemblies are provided, each group of movable claw head assemblies corresponds to a guide groove, and a slide rod bracket 12 passes through the guide groove and the cross-shaped slide from bottom to top, and each side groove of the cross-shaped slide is penetrated by a slide rod bracket 12.

[0050] The toothed belt transmission assembly includes a toothed belt 3 and a toothed belt storage part 21. The toothed belt storage part 21 is connected to the shell. A belt cavity 22 for sliding and storing the toothed belt 3 is provided inside the toothed belt storage part 21. The toothed belt 3 is engaged with the gear 1 for transmission, and one end of the toothed belt 3 is fixedly connected to the movable claw head assembly.

[0051] The movable claw head assembly includes a slide rod bracket 12 and a movable clamping head assembly. One end of the slide rod bracket 12 is fixedly connected to the toothed belt 3 by a toothed belt fixing screw 4; the slide rod bracket 12 passes through the guide groove and the top slide groove, and the movable clamping head assembly is connected to the top of the slide rod bracket 12. The slide rod bracket 12 is provided with a protrusion that is adapted to the inner recessed portion. The protrusion cooperates with the inner recessed portion to ensure that the slide rod bracket 12 slides stably in the guide groove.

[0052] The movable chuck assembly includes a movable chuck 13, a spring 5 and a torque nut 20. The movable chuck 13 is provided with a protrusion, which passes through the slide rod bracket 12 and is threadedly connected to the torque nut 20. A spring 5 is connected between the movable chuck 13 and the slide rod bracket 12. Two springs 5 ​​are provided, and the two springs 5 ​​are respectively located on both sides of the protrusion.

[0053] Tightening the torque nut 20 can compress the spring 5 to store energy. The number of tightening turns is adjusted according to the gravity of the material, the number of clamping jaws and the friction resistance F=μN to ensure that after the stepper motor stops, the total friction resistance of the claw surface is greater than the gravity of the material, so that the material can be clamped and prevented from falling.

[0054] The spring force of the movable chuck assembly (13) can be adjusted by tightening the torque nut (20). Numerical markings are engraved on the side of the torque nut (20) to facilitate force adjustment. Adjustment of the spring force is based on the material's mass, the clamping area, and the number of jaws required. After the stepper motor (9) stops, the clamping force is maintained to prevent the material from falling due to mass and weight.

[0055] The gear 1 adopts a double-row gear, and the double-row gear is staggered up and down and connected to multiple groups of gear transmission components. Each group of gear transmission components is connected to a group of movable claw head components. The sliding rod bracket 12 of the movable claw head components at different positions only has different heights, which is convenient for having the same clamping height on the clamping claw upper cover 15.

[0056] The clamping sensor assembly includes a clamping sensor 17 and a clamping sensor sheet 16 . The clamping sensor sheet 16 is connected to the movable clamp 13 , and the clamping sensor 17 is connected to the slide rod bracket 12 .

[0057] The release sensing assembly includes a release sensor 24 and a release sensing sheet 23 . The release sensor 24 is connected to the housing, and the release sensing sheet 23 is connected to the slide rod bracket 12 .

[0058] The electric clamping jaws in the present invention are modularly designed with a movable clamping head 13, a slide rod bracket 12, a toothed belt 3, a guide groove and a top slot (cross slot). Flexible optional modes can be used to correspond to different material shapes to be clamped. The 19 fixing screws connecting the clamping jaw upper cover 15 and the motor fixing plate 10 are loosened, and the clamping jaw upper cover 15 can be removed. The movable clamping head assembly can be slidably installed along the guide groove formed by the guide plate 6 and the upper and lower cover plates. It can be optionally equipped with 2-jaw clamping, 3-jaw clamping, and 4-jaw clamping modes, so that a set of clamps can be suitable for various material shapes and improve economic benefits.

[0059] Driven by the two rows of gears, the working parts of the teeth are driven synchronously, and the movable clamping head 13 is clamped inwards to facilitate centering.

[0060] During installation, the reference angle of the dial 18 is controlled according to the shape of the material. First, the mobile claw assembly with the meshing jaw position close to the center is assembled, and then the subsequent mobile claw assembly is assembled according to the corresponding angle, number of meshing teeth and distance length of the dial 18. The relative position of the movable clamping heads 13 is adjusted by adjusting the number of installed staggered teeth to adapt to various objects with irregular shapes and contours.

[0061] The movable chuck 13 is installed for materials with irregular shapes. The movable chuck 13 is selected according to the shape. The deviation distance between each movable chuck 13 when clamping the material is measured according to the shape. Each movable chuck 13 is installed and inserted into the transmission toothed belt. The tooth pitch can be staggered according to the deviation distance for meshing. The distance between each movable chuck 13 is controlled, which is conducive to the clamping of materials with irregular shapes.

[0062] When clamping the material, the forward key drive of stepper motor 9 drives the double-row gears in forward rotation. This toothed drive displaces the toothed belt 3 into the interior of the clamp, which in turn drives the slide bracket 12. The middle portion of the slide bracket engages with the recessed portion of the guide rail assembly, supporting and guiding the slide bracket 12 inward along the top chute. During this displacement, the rear end of the toothed belt 3 moves inward along the arc-shaped guide surface of the belt cavity 22. Due to the clamp's stroke control, the toothed belt 3's length meets the required stroke length for clamping and loosening. The arc-shaped groove of the belt cavity accommodates the toothed belt's displacement during inward displacement. After the torque nut 20 is tightened, the movable clamp 13 slides along the slide bracket 12, driving the clamping sensor 16 mounted on its side toward the working end of the clamping sensor 17. When the appropriate distance is reached, the clamping sensor 17's circuit is energized, sending an electrical signal to the PLC to stop the stepper motor 9, while maintaining the material's clamping position.

[0063] When loosening the material, the reverse key of the stepper motor 9 drives the double-row gears to reverse, the tooth transmission drives the toothed belt 3 to move toward the outside of the fixture, and the toothed belt 3 drives the slide rod bracket 12 to move toward the outside of the fixture. The middle part of the slide rod bracket cooperates with the inner recess on the guide rail assembly to support and guide the slide rod bracket 12 to move outward on the top slide; the slide rod bracket 12 continues to approach the loosening sensor 24, and when the distance between the loosening sensor sheet 23 and the working end of the loosening sensor 24 is appropriate, the working circuit of the loosening sensor 24 is connected, and an electrical signal is sent to the PLC to control the stepper motor to stop.

[0064] The electric clamping mechanism disclosed in this invention rotates a double-row gear by manually turning a dial. The gears, through meshing, drive the toothed belt 3 and the slide bar bracket to slide inward along guide rail 12. A movable clamp 13 for concentric material is installed. Multiple movable clamps 13, evenly spaced around the circumference, can be simultaneously inserted into the toothed belt 3. Manually synchronizing the movable clamps 13 allows for synchronized displacement, facilitating the centering and clamping of concentric parts.

[0065] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
