Technical Field

[0001] The present application relates to the field of wire drawing, and in particular to a clamp for a robot and a wire drawing machine thereof. Background Art

[0002] At present, during the operation of the wire drawing machine, the product is placed in a material tray, and the robot grasps the product through the suction cup of the clamp and drives the product to contact the rotating wire drawing wheel to achieve wire drawing processing on the product surface.

[0003] In actual work, since the wire drawing width of some products is smaller than the width of the wire drawing wheel, the peripheral side of the wire drawing wheel is worn, resulting in a stepped shape on the peripheral side of the wire drawing wheel. In order to ensure the wire drawing effect of the product, the peripheral side of the wire drawing wheel needs to be polished and smoothed.

[0004] In the related art, manual processing is usually adopted, that is, the worker holds a scraper in hand and contacts the rotating drawing wheel. In this process, since the debris on the surface of the drawing wheel is easy to splash, the safety is poor, so improvement is needed. Utility Model Content

[0032] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] The following is combined with Figure 1-2 This application is described in further detail.

[0034] An embodiment of the present application discloses a clamp for a robot.

[0035] Reference Figure 1 The fixture includes a mounting frame 1, two adsorption components 2 and a polishing component 3, wherein the mounting frame 1 includes a frame body 11, the upper end of the frame body 11 is cylindrically arranged to be fixed to the robot, and the two adsorption components 2 are arranged on opposite sides of the lower end of the frame body 11.

[0036] Specifically, the adsorption assembly 2 includes a ventilation column 21 and a suction cup 22. The ventilation column 21 is installed on the frame 11 and is arranged along the length direction of the frame 11. The suction cup 22 is fixedly connected to the lower end of the ventilation column 21 and is communicated with the ventilation column 21. In the present embodiment, the upper end of the ventilation column 21 is communicated with the upper end of the frame 11 through an air pipe (not shown in the figure), and the vacuum device on the manipulator is connected to the upper end of the frame 11 to realize the vacuum of the ventilation column 21, so that the ventilation column 21 becomes a vacuum state, so that the suction cup 22 adsorbs the product.

[0037] The grinding assembly 3 includes a scraper 31, which is in the shape of a rectangular plate. The scraper 31 is installed on the other side of the frame 11 so that the scraper 31 is located between the two suction cups 22. It should be noted that the length of the scraper 31 away from the frame 11 is greater than the width of the drawing wheel, ensuring that during the grinding process, the scraper 31 can contact the entire width of the drawing wheel to achieve a stable grinding effect.

[0038] In actual application, the upper end of the frame 11 is fixedly connected to the manipulator, so that the manipulator can drive the mounting frame 1 to move so that the two suction cups 22 are in contact with the product, and the vacuum equipment evacuates the two ventilation columns 21 so that the two suction cups 22 adsorb the product, thereby achieving the grasping of the product.

[0039] When it is necessary to grind the peripheral side of the wire drawing wheel, it is only necessary to control the robot to drive the mounting frame 1 to move so that the scraper 31 contacts the wire drawing wheel on the side away from the frame body 11. The scraper 31 grinds the peripheral side of the wire drawing wheel to make it smooth, thereby realizing automatic grinding of the wire drawing wheel. During this grinding process, there is no need to manually hold the scraper 31, thereby improving the safety of grinding the wire drawing wheel.

[0040] Reference Figure 1 and Figure 2 In some embodiments, the grinding assembly 3 also includes a locking block 32, a pressing block 33 and a fixing piece 34. The locking block 32 and the pressing block 33 are both arranged in a rectangular block shape. The locking block 32 is fixedly connected to the frame 11. The pressing block 33 is located on one side of the locking block 32. The fixing piece 34 is a bolt. One end of the fixing piece 34 is movably inserted into the pressing block 33 and threadedly connected to the locking block 32, and the other end abuts against the pressing block 33. One side of the scraper 31 is located between the pressing block 33 and the locking block 32. The scraper 31 can be tightened or loosened by rotating the fixing piece 34. The structure is simple and convenient for installing and disassembling the scraper 31, thereby facilitating the maintenance or replacement of the scraper 31.

[0041] In some embodiments, a clearance hole 311 is opened on the scraper 31, and the fixing member 34 is passed through the clearance hole 311 to further limit the scraper 31 and try to prevent the scraper 31 from being displaced during operation, thereby improving the working stability of the scraper 31.

[0042] In some embodiments, the locking block 32 is detachably connected to the frame 11. In this embodiment, the locking block 32 is fixed to the frame 11 by bolts to achieve the detachable connection of the locking block 32. In other embodiments, the detachable connection of the locking block 32 can also be achieved by snapping, plugging or using other connectors, which is not limited by this application. This arrangement is convenient for improving the original clamp, and the structure is simple to reduce production and R&D costs.

[0043] Reference Figure 1 In some embodiments, the mounting frame 1 further comprises an abutment plate 12, which is fixedly connected to the lower end of the frame body 11, and the abutment plate 12 is provided with two clearance grooves 13 spaced apart along its length direction, and two suction cups 22 are respectively penetrated through the clearance grooves 13, wherein the suction cups 22 partially protrude from the lower side of the abutment plate 12, so as to facilitate the adsorption of the product and enable the suction cups 22 to better contact with the product, and the distance between the suction cups 22 and the lower side of the abutment plate 12 is small, so that the product abuts against the side of the abutment plate 12 away from the frame body 11, so as to improve the stability of the adsorption of the product.

[0044] In some embodiments, the adsorption assembly 2 also includes two limiting nuts 23. Both sides of the frame 11 are arranged in a rectangular plate shape and are provided with mounting holes 14. The ventilation column 21 is passed through the mounting holes 14. The two limiting nuts 23 are threadedly connected to the ventilation column 21, and the lower end of one of the limiting nuts 23 abuts against the frame 11, and the upper end of the other limiting nut 23 abuts against the frame 11, so as to achieve the limiting fixation of the ventilation column 21, and the distance between the ventilation column 21 and the abutting plate 12 can be adjusted, so that it can be suitable for products of different sizes and shapes to improve the applicability of the clamp.

[0045] In some embodiments, the mounting hole 14 and the clearance groove 13 are both arranged in a strip shape and the length direction is arranged along the length direction of the abutment plate 12. In this way, the distance between the two suction cups 22 can be adjusted within a certain range to improve the stability of product adsorption, and it can also be suitable for products of different lengths.

[0046] The implementation principle of this embodiment is: in actual application, the upper end of the frame 11 is fixedly connected to the manipulator, so that the manipulator can drive the mounting frame 1 to move so that the two suction cups 22 are in contact with the product, and the vacuum equipment evacuates the two ventilation columns 21 so that the two suction cups 22 adsorb the product, thereby achieving the grasping of the product.

[0047] When it is necessary to grind the peripheral side of the wire drawing wheel, it is only necessary to control the robot to drive the mounting frame 1 to move so that the scraper 31 contacts the wire drawing wheel on the side away from the frame body 11. The scraper 31 grinds the peripheral side of the wire drawing wheel to make it smooth, thereby realizing automatic grinding of the wire drawing wheel. During this grinding process, there is no need to manually hold the scraper 31, thereby improving the safety of grinding the wire drawing wheel.

[0048] The embodiment of the present application also discloses a wire drawing machine.

[0049] The wire drawing machine includes the clamp described in the above embodiment.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
