Description

Technical Field

[0001] The utility model belongs to the technical field of steel plate groove processing devices, and in particular relates to a clamp for convenient steel plate groove cutting. Background Art

[0002] Beveling is an indispensable part of the steel plate production process. Whether it is in the automotive, machinery, construction and other industries, steel plate beveling is essential. As the name suggests, steel plate beveling is to process the surface of the steel plate through various beveling tools to make it reach a certain shape and size to meet different application requirements. A commonly used beveling is grinding beveling. Beveling can improve the surface quality and service life of the steel plate. After beveling, the steel plate has a smoother surface, less roughness, and improved wear and corrosion resistance, making it more durable during application. However, beveling is also accompanied by disadvantages such as poor working environment, high noise, high temperature and high risk. Therefore, with the development of science and technology, industrial robots have begun to be put into production. Industrial robots pick up steel plates to the workbench through fixtures and then perform beveling, gradually replacing manual labor to become the main force of steel plate beveling.

[0003] In the existing technology, the picking end of the industrial robot clamp mainly relies on the electromagnetic suction cup to adsorb the steel plate to achieve the fixing effect. However, due to the uneven surface of some steel plates and the tilt of the steel plate stack caused by poor preliminary work, the existing clamp cannot adapt to this situation well. As a result, in the process of adsorbing the steel bars, the steel plates frequently impact the electromagnetic suction cup, which has a certain impact on the service life of the electromagnetic suction cup, thereby increasing the production and management costs.

DETAILED DESCRIPTION

[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figure 1-Figure 5 A clamp for convenient steel plate groove cutting shown in FIG. 1 includes a frame 1 , a connecting end 2 is fixedly connected to the top of the frame 1 , and a cutting head 3 and a visual camera 4 are fixedly connected to both sides of the frame 1 .

[0025] Through such a design, the present application can be installed on an industrial robot and perform bevel cutting work.

[0026] The frame 1 is externally connected with a spacing adjustment component, and the spacing adjustment component is used to adjust the distance between the two picking ends 14. The spacing adjustment component includes a motor 7, a fixed plate 5 and two guide rails 11 which are respectively fixedly connected to the top, one side and the inner wall of the frame 1. The output end of the motor 7 is rotatably connected and inserted to the outside of the fixed plate 5 on the side away from the frame 1. The output end of the motor 7 is fixedly connected with a driving wheel 8, and a driven wheel 9 is arranged below the driving wheel 8. The driving wheel 8 and the driven wheel 9 are tensioned by a belt. One end of the driven wheel 9 is fixedly connected with a positive and negative screw rod 10, and the positive and negative screw rod 10 is rotatably connected and inserted into the interior of the frame 1. The outer wall of the positive and negative screw rod 10 is screwed with two nuts 12, and the outer wall of the nut 12 is fixedly connected with a moving seat 13, and the moving seat 13 is slidably connected to the outer wall of the guide rail 11, and the picking end 14 is fixedly connected to the bottom of the moving seat 13.

[0027] In the above setting, the controller starts the motor 7 to drive the driving wheel 8 to drive the driven wheel 9 and the forward and reverse screw rods 10 to rotate synchronously, thereby driving the two nuts 12 and the two moving seats 13 to move toward each other, and synchronously adjusting the distance between the picking ends 14. Through such a design, the user can adjust the distance between the picking ends 14 according to needs, which is convenient for use.

[0028] A side of the fixing plate 5 away from the outer wall of the frame 1 is fixedly connected with a hood 6 , and the driving wheel 8 and the driven wheel 9 are both located inside the hood 6 .

[0029] Through such a design, a certain degree of protection can be provided for the driving wheel 8 and the driven wheel 9.

[0030] The bottom of the spacing adjustment component is connected to two picking ends 14, which are used to adsorb the steel plate. The picking end 14 includes a suspension, a first buffer component, an electromagnetic suction cup 23 and two second buffer components. The first buffer component is located between the suspension and the electromagnetic suction cup 23, and the second buffer component is located on one side of the electromagnetic suction cup 23. The suspension component includes a mounting plate 15 fixedly connected to the bottom of the moving seat 13, and the four bottom corners of the mounting plate 15 are fixedly connected to support columns 17, and the bottom of the support column 17 is fixedly connected to a connecting plate 16.

[0031] In the above setting, the first buffer component is arranged between the electromagnetic suction cup 23 and the suspension part. When the electromagnetic suction cup 23 adsorbs the steel plate, the first buffer component will offset the impact caused by the contact between the steel plate and the electromagnetic suction cup 23, thereby reducing the impact on the entire application. By setting the second buffer component, the impact on the electromagnetic suction cup 23 itself when the steel plate contacts the electromagnetic suction cup 23 is reduced. Through such a design, during the transportation and processing of the steel plate, the impact caused by the contact between the steel plate and the industrial robot as a whole is reduced, thereby solving the problem of large impact on the fixture and the industrial robot itself caused by the adsorption of the steel plate and the low service life in the prior art.

[0032] The first buffer assembly includes two sleeves 19 fixedly connected to the bottom of the mounting plate 15, and two sleeves 18 at the top of the connecting plate 16, and also includes a movable rod 20 inserted and slidably connected inside the sleeves 19 and 18, one end of the movable rod 20 is fixedly connected to the top of the electromagnetic suction cup 23, the outer wall of the movable rod 20 is fixedly connected to a limiting plate 28, and the limiting plate 28 is located at the top of the sleeve 19, a spring 21 is fixedly connected between the sleeve 18 and the limiting plate 28, the outer wall of the movable rod 20 is sleeved with a spring 22, and the two ends of the spring 22 are respectively fixedly connected to the bottom of the sleeve 19 and the top of the electromagnetic suction cup 23.

[0033] In the above setting, when the electromagnetic suction cup 23 adsorbs the steel plate, the impact it brings will drive the movable rod 20 to slide inside the sleeve 2 19 and the sleeve 1 18, while compressing the movable rod 20 and the spring 2 22. Through such a design, the impact brought by the steel plate can be buffered to a certain extent.

[0034] An elastic sleeve 31 is fixedly connected to the inside of sleeve 2 19, and the elastic sleeve 31 is slidably connected to the movable rod 20. An adapter is fixedly connected to the top of the movable rod 20, and the adapter includes a movable plate 30 slidably connected to the inside of sleeve 18, and a movable ball 29 is fixedly connected to the bottom of the movable plate 30, and the movable ball 29 is rotatably connected to the inside of the movable rod 20.

[0035] In the above arrangement, if the surface of the steel plate is uneven or the steel plate stack is tilted, the movable rod 20 can squeeze the elastic sleeve 31 to deflect to a certain extent during the adsorption process. At the same time, a gap is left inside the sleeve 18, so that the movable rod 20 is correspondingly offset along the movable ball 29. Through such a design, non-straight impacts can be buffered.

[0036] The second buffer component includes two fixing components 24 fixedly connected to one side of the electromagnetic suction cup 23, and the interiors of the two fixing components 24 are both inserted and slidably connected with a shaft buffer component 25, and the outer wall of the shaft buffer component 25 is fixedly connected with a spring three 27, and a limiting plate one 26 is fixedly connected between the spring three 27 and a fixing component 24 located above, and the limiting plate one 26 is sleeved on the outside of the shaft buffer component 25.

[0037] In the above setting, when the steel plate is adsorbed, it first contacts with the shaft buffer 25, and the impact thereof drives the shaft buffer 25 to drive the spring three 27 to move upward, and simultaneously compress the limit plate one 26. Through such a design, the steel plate is unloaded once before contacting the electromagnetic suction cup 23, thereby reducing the impact on the electromagnetic suction cup 23.

[0038] Working principle:

[0039] The controller starts the motor 7 to drive the driving wheel 8 to drive the driven wheel 9 and the forward and reverse screw rods 10 to rotate synchronously, thereby driving the two nuts 12 and the two moving seats 13 to move toward each other, and synchronously adjusting the distance between the picking ends 14. Through such a design, the user can adjust the distance between the picking ends 14 according to the needs, which is convenient for use;

[0040] The first buffer component is arranged between the electromagnetic suction cup 23 and the suspension part. When the electromagnetic suction cup 23 adsorbs the steel plate, the first buffer component will offset the impact caused by the contact between the steel plate and the electromagnetic suction cup 23, thereby reducing the impact on the entire application. By setting the second buffer component, the impact on the electromagnetic suction cup 23 itself when the steel plate contacts the electromagnetic suction cup 23 is reduced. Through such a design, the impact caused by the contact between the steel plate and the industrial robot as a whole is reduced during the handling and processing of the steel plate, which solves the problem of large impact on the fixture and the industrial robot itself caused by the adsorption of the steel plate in the prior art and low service life;

[0041] When the electromagnetic suction cup 23 adsorbs the steel plate, the impact caused by it will drive the movable rod 20 to slide inside the sleeve 2 19 and the sleeve 1 18, and compress the movable rod 20 and the spring 2 22 at the same time. Through such a design, the impact caused by the steel plate can be buffered to a certain extent;

[0042] If the steel plate surface is uneven or the steel plate stack is tilted, the movable rod 20 can squeeze the elastic sleeve 31 to deflect to a certain extent during the adsorption process. At the same time, a gap is left inside the sleeve 18, so that the movable rod 20 deflects accordingly along the movable ball 29. Through such a design, non-straight impacts can be buffered;

[0043] When the steel plate is adsorbed, it first contacts with the shaft buffer 25, and the impact thereof drives the shaft buffer 25 to drive the spring three 27 to move upward, and simultaneously compress the limit plate one 26. Through such a design, the steel plate is unloaded once before contacting the electromagnetic suction cup 23, thereby reducing the impact on the electromagnetic suction cup 23.
