Description
Technical Field
[0001] The utility model relates to a clamping claw, in particular to a servo clamping claw. Background Art
[0002] During the production and processing of parts, grippers are usually used for handling. Existing grippers generally use pneumatic clamping, which is not compatible with the size of the clamped products. Therefore, different grippers need to be replaced to meet the compatibility issue. This leads to long changeover time, cumbersome operation, and inability to mass produce. Utility Model Content

Grooves are provided on one end of the clamping block and the support plate, and the two ends of the spring are respectively arranged in the grooves. The other end of the clamping block protrudes from the clamping plate. The clamping block presses the spring by abutting against the protruding part to clamp the object, so as to eliminate the gap between the clamped object and the clamping plate and ensure stable clamping.
[0008] Furthermore, a limiting plate is relatively arranged on the mounting plate, and the plane where the limiting plate is located is perpendicular to the plane where the clamping plate is located, so that the product is clamped and limited from another direction.
[0009] Furthermore, an avoidance opening is provided on the clamping plate to facilitate avoiding clamping objects.
[0010] Furthermore, protective covers are provided on the outside of the rack and the gear to prevent damage to the gear and rack structures.
[0011] The benefit of this application is that the servo clamp provided drives the gear to rotate through the servo motor, and then drives the rack to move, thereby realizing the movement of the splints to adjust the spacing distance between the splints, which is compatible with the size of the grasped objects and improves production efficiency.

[0022] See also Figure 1-Figure 3 The present embodiment provides a servo clamp, including a mounting plate 10, on which a servo motor 11 is arranged, and a gear 12 is arranged at the output end of the servo motor 11 through the mounting plate, and slide rails 13 are respectively arranged on the mounting plates on both sides of the gear 12, and two sets of slide rails 13 are arranged in parallel, and a mounting block 14 is arranged on each slide rail 13 through a slider, and a mounting groove is provided in the mounting block 14, and the opening direction of the mounting groove is also parallel to the slide rail, and a rack 15 is fixedly arranged in the mounting groove, and the two sets of racks 15 are meshed with the gear 12, and each rack 15 is provided with a clamping plate 17, and one of the clamping plates 17 is provided with a floating clamping component 18.
[0023] In the initial state, the mounting blocks 14 on the two sets of slide rails are staggered, that is, they are not on the same side. A connecting plate 16 is provided on each rack 15. The connecting plate 16 is divided into a horizontal connecting part and a vertical connecting part. The horizontal connecting part and the vertical connecting part are arranged vertically. The horizontal connecting part is connected to the rack 15, and the vertical connecting part is connected to the clamping plate 17. The vertical connecting parts on the two sets of connecting plates 16 are also staggered, so as to ensure the maximum clamping range to be compatible with the size of the clamped object.
[0024] Specifically, the floating clamping assembly 18 includes a support plate 181 connected to the bottom end of the clamping plate 17, and an L-shaped groove 171 is opened at the bottom end of the clamping plate. At least a portion of the support plate 181 covers the outer side of the L-shaped groove, and a through hole is opened inward along the bottom wall of the L-shaped groove 171. A clamping block 182 is set in the through hole. Both ends of the clamping block 182 are protruding from the clamping plate 17, and a groove is opened at one end in the L-shaped groove. A groove is also opened on the support plate 181. A spring 183 is set between the two groups of grooves. The clamped object is clamped by abutting the protruding part to realize the clamping block to clamp the spring, thereby realizing floating clamping of the clamped object by the clamping block, so as to eliminate the gap between the clamped object and the clamping plate and ensure stable clamping.
[0025] In addition, a U-shaped escape opening 172 is provided at the bottom end of the clamping plate 17. The escape opening 172 is a U-shaped opening, and the pressure blocks 182 include two sets, one set on each side of the U-shaped escape opening. Similarly, the corresponding positions of the support plate 181 also have escape openings. Support bosses 173 are provided at the bottom end of the clamping plate 17 on both sides of the U-shaped escape opening to support the clamped object. In this embodiment, the mounting plate 10 is constructed as a rectangular plate, and the two sets of clamping plates 17 are respectively provided along two opposite sides of the rectangular plate. Limiting plates 19 are provided on the other two side edges of the mounting plate to limit the clamped object from two other directions, ensuring the stability of the clamping process.
[0026] Since the gears and racks are precision components, a protective cover 20 is set along the edge of the mounting plate 10 toward the clamping plate. The bottom end of the protective cover 20 does not affect the clamping. The protective cover is used to prevent dust from entering the gears and racks and affecting the movement, and can also prevent the internal structure of the protective cover 20 from being damaged.
[0027] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
