Description

Technical Field

[0001] This utility model relates to the field of steel structure clamping technology, specifically a steel structure punching clamping device. Background Technology

[0002] Steel structure punching is a process in which pressure is applied to a steel plate using a die, causing localized plastic deformation of the material and forming the desired holes. Its principle is similar to shearing. Holes are punched directly into the steel plate using stamping machinery. Especially when punching square tubes, the clamping devices are often custom-made structures that need to be wrapped and positioned according to the size of the square tube.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN217889319U) discloses a punching device for steel structure production and processing. The device includes a workbench with supporting legs fixedly installed on its lower outer surface. A control panel is located on the front outer surface of the workbench. A pneumatic punching machine body is mounted on the upper outer surface of the workbench, and a waste collection plate is located in the middle of one side of the pneumatic punching machine body. This utility model's punching device for steel structure production and processing incorporates a pneumatic lifting and clamping device. Rubber protective pads effectively prevent deformation of the steel body, protecting it from damage. When the pressure block is pressed down, it can slide within positioning grooves via sliders on both sides, ensuring stable pressing and fixing. The simple structure not only improves the convenience of fixing the steel body and increases work efficiency but also enhances the stability of the steel body during punching, facilitating drilling by the pneumatic punching machine and improving drilling accuracy.

[0004] The clamping device of the steel structure punching equipment mentioned above is a customized mold structure, which is usually selected according to the external dimensions of the square tube to be processed to achieve external wrapping and positioning of the square tube. Therefore, the use of its clamping device can only achieve clamping and positioning of square tubes of a single model and size, and cannot clamp and position square tubes of different sizes. This greatly reduces the adaptability and flexibility of the clamping device used on existing punching equipment. When multiple specifications of square tubes need to be punched, the clamping device needs to be changed back and forth, which reduces the working efficiency of the punching machine.

[0005] Therefore, this utility model provides a steel structure punching clamping device to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved This utility model provides a steel structure processing punching clamping device, which aims to solve the problems mentioned in the background art.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a steel structure processing punching clamping device, including a base, with clamping plates provided on both sides of the base, and a cylinder fixedly connected to the top of the clamping plates, and a pressure plate fixedly connected to the lifting end of the cylinder; The adjustment component and clamping plate are provided. There are two sets of clamping plates. The adjustment component is located inside the base and is used to adjust the relative position of the two sets of clamping plates. Each set of clamping plates has two limiting grooves, and pressure plates are slidably arranged inside the limiting grooves.

[0008] As a preferred technical solution of this application, the adjustment component includes a servo motor and a bidirectional lead screw. The servo motor is fixedly connected to the outer wall of the base, and the two ends of the bidirectional lead screw are rotatably connected to the base through ball bearings. The bidirectional lead screw has a hexagonal groove corresponding to the output shaft of the servo motor, and the output shaft of the servo motor is inserted into the hexagonal groove.

[0009] As a preferred technical solution of this application, the bidirectional lead screw is symmetrically connected to two sets of nut pairs on the outside. Each set of nut pairs is connected to a sleeve on the outside, and a guide seat is integrally connected to the outer wall of the sleeve. Guide sleeves are provided at both ends of the guide seat, and a guide shaft is inserted into the inside of the guide sleeve.

[0010] As a preferred technical solution of this application, the guide shaft is fixedly connected to the inner wall of the base, the top of the guide seat is T-shaped, and a rectangular groove is provided on the top of the base corresponding to the T-shaped structure of the guide seat. A clamping plate is fixedly connected to the top of the T-shaped structure of the guide seat.

[0011] As a preferred technical solution of this application, the pressure plate has a rectangular frame structure, and a set of cylinders is provided at each of the bottom corners of the pressure plate.

[0012] As a preferred technical solution of this application, the two sets of clamps are provided with rotating grooves at both ends of the side that are close to each other, and the rotating grooves are rotatably connected to rollers, the outer walls of the rollers protruding to the outer side of the clamp surface.

[0013] (III) Beneficial Effects The beneficial effects of this application are as follows: This utility model, through the adjustable structure, allows for the adjustment of the wrapping area of ​​the pressure plate by adjusting its vertical position and the left and right position of the clamping plate. This enables the device to effectively adapt to square tubes of different sizes for clamping and positioning, thereby improving its clamping adaptability.

[0014] This utility model, through the setting of the adjustment component, can drive two sets of clamping plates to move synchronously through the bidirectional screw transmission structure, so that they move closer or further away at the same time, thereby ensuring the centering of the square tube clamping. No additional centering adjustment of the square tube is required, further improving its ease of use. At the same time, the setting of rollers inside the clamping plate allows the side of the square tube to roll and contact with the rollers, which not only limits the square tube but also reduces its wrapping friction.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-5As shown, this utility model provides a steel structure processing punching clamping device, including a base 1, with clamping plates 11 on both sides of the base 1, and a cylinder 12 fixedly connected to the top of the clamping plates 11, and a pressure plate 13 fixedly connected to the lifting end of the cylinder 12; an adjustment component 2 and clamping plates 3, with two sets of clamping plates 3. The adjustment component 2 is located inside the base 1 and is used to adjust the relative position of the two sets of clamping plates 3. Each set of clamping plates 3 has two limiting grooves 31, and the pressure plate 13 is slidably arranged inside the limiting grooves 31. By the left and right displacement of the clamping plates 3 and the up and down adjustment of the pressure plate 13, the clamping area size of the pressure plate 13 and the clamping plates 3 can be flexibly adjusted, so that the device can effectively adapt to square tubes of different sizes for clamping and positioning.

[0019] Furthermore, the adjustment component 2 includes a servo motor 21 and a bidirectional lead screw 22. The servo motor 21 is fixedly connected to the outer wall of the base 1. The two ends of the bidirectional lead screw 22 are rotatably connected to the base 1 through ball bearings. The bidirectional lead screw 22 has a hexagonal groove corresponding to the output shaft of the servo motor 21, and the output shaft of the servo motor 21 is inserted into the hexagonal groove. The hexagonal insertion connection of the output shaft of the servo motor 21 facilitates the rotation drive of the bidirectional lead screw 22, and also facilitates the disassembly and replacement of the servo motor 21. Only the servo motor 21 needs to be disassembled and reassembled. Through the insertion of the output shaft of the servo motor 21 into the hexagonal groove of the bidirectional lead screw 22, the bidirectional lead screw 22 can be driven to rotate under the drive of the servo motor 21.

[0020] Furthermore, two sets of nut pairs 23 are symmetrically connected to the outside of the bidirectional lead screw 22. Each set of nut pairs 23 is connected to a sleeve 24, and a guide seat 25 is integrally connected to the outer wall of the sleeve 24. Guide sleeves 26 are provided at both ends of the guide seat 25, and a guide shaft 27 is inserted into the inside of the guide sleeve 26. By rotating the bidirectional lead screw 22, the nut pairs 23 at both ends are driven to move synchronously. The sleeve 24 and the guide seat 25 can drive the upper clamping plate 3 to move synchronously and adjust, thereby realizing the clamping and limiting of square tubes of different widths. The sliding connection between the guide sleeve 26 and the guide shaft 27 is used to guide and limit the displacement of the nut pairs 23, ensuring the stability of the horizontal displacement of the nut pairs 23.

[0021] Furthermore, the guide shaft 27 is fixedly connected to the inner wall of the base 1, the top of the guide seat 25 is T-shaped, and a rectangular groove is provided on the top of the base 1 corresponding to the T-shaped structure of the guide seat 25. A clamping plate 3 is fixedly connected to the top of the T-shaped structure of the guide seat 25. The pressure plate 13 is rectangular frame structure, and a set of cylinders 12 are provided at the bottom corners of the pressure plate 13. Through the engagement of the pressure plate 13 and the limiting groove 31, the relative displacement of the pressure plate 13 and the clamping plate 3 can be realized, thereby realizing the adaptive adjustment of the height and width of the clamping area.

[0022] Furthermore, rotating grooves 32 are provided at both ends of the two sets of clamping plates 3 that are close to each other, and rollers 33 are rotatably connected inside the rotating grooves 32. The outer wall of the rollers 33 protrudes to the outer side of the clamping plate 3. By setting the rotating rollers 33, the side of the square tube is abutted and limited. The rolling contact replaces the planar contact, which not only assists in positioning but also reduces the contact friction and improves the smoothness of the square tube displacement.

[0023] Working principle: First, the spacing between adjacent clamping plates 3 is adjusted according to the size of the square tube to be processed. The square tube is placed above the base 1, and then the servo motor 21 is driven. Under the control of the servo motor 21, the bidirectional lead screw 22 is rotated. Furthermore, the displacement of the nut pair 23 drives the sleeve 24 and the guide seat 25 to move horizontally, thereby realizing the relative displacement of the clamping plates 3 on both sides. By the clamping plates 3 approaching each other, the square tube is centered and clamped. When the roller 33 contacts the outer wall of the square tube, the auxiliary positioning of the clamping plates 3 is completed. Then, the cylinder 12 is controlled to descend so that the pressure plate 13 is at the top of the square tube. After the device is installed and positioned, the center position of the center distance between the two sets of clamping plates 3 is the punching part, avoiding the pressure plate 13 from obstructing the punching part, while satisfying its multi-size adaptability clamping.

[0024] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
