[0023] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0024] like Figure 1-Figure 2 As shown, a square tube punching device includes a splint 101 fixedly assembled at the output end of the drilling device 1, a bracket 2 is provided below the splint 101, and a support 103 is fixedly connected to one side of the bracket 2. The splint 101 is arranged in an L-shape, and a connecting ring 106 is symmetrically fixedly connected to one side of the splint 101. The middle part of the connecting ring 106 is rotatably connected to a screw 107, and the outer wall of the screw 107 is fixedly connected to a clamping ring 108 below the connecting ring 106. The threaded end of the screw 107 is threadedly connected to the support 103, and the two sides of the support 103 are fixedly connected to the side plates 104. The two sides of the splint 101 are symmetrically fixedly connected to the support plates 102, and the support plates 102 are slidably connected to the side plates 104 through the limiting rods 105.

[0025] According to the above structure, the square tube is placed on the top of the bracket 2, and the screw 107 is rotated to make it rise or retract from the inside of the support 103. The screw 107 drives the connecting ring 106 and the splint 101 to move up or down through the clamping ring 108, thereby adjusting the gap between the splint 101 and the bracket 2. The support plate 102 is slidably connected with the side plate 104 through the limiting rod 105, and the angle of the splint 101 can be limited when the screw 107 rotates.

[0026] Refer to the attached Figure 1 、 Figure 3-Figure 6The bracket 2 is set as a cavity with a through middle, and a through slot 201 is provided at both ends of the bracket 2. A plurality of partitions 202 are fixedly connected to one side of the through slot 201 at equal distances. A panel 207 is symmetrically and movably provided on the top of the bracket 2. A through slot 215 for engaging with the partition 202 is provided at equal distances on one side of the panel 207. A mounting slot 203 for engaging with the panel 207 is provided on the top of the partition 202. A wedge plate 214 is fixedly connected to one side of the panel 207 and located between the two partitions 202. The panel 207 is fixedly connected to the bracket 2 through a spring column 213 on one side. A vertical plate 209 is symmetrically fixedly connected to the middle of the bracket 2, and the inlaid plate 207 is slidably connected to the vertical plate 209 through a slider 205. A sliding plate 204 is slidably connected between the two partitions 202. Several sliding plates 204 are fixedly connected by a wedge plate 210. The wedge plate 210 is arranged inside the bracket 2 and is located on one side of the wedge plate 214. A baffle 212 is fixedly connected to the bottom of the partition 202. The baffle 212 is elastically connected to the wedge plate 210 through a spring column 211. A roller 206 is rotatably assembled at one end of the sliding plate 204, and a friction ball 208 is fixedly connected to the top of the bracket 2.

[0027] According to the above structure, when the square tube is placed on the top of the bracket 2, the panel 207 is pressed down, the panel 207 is embedded in the embedding groove 203, the top of the panel 207 is flush with the bracket 2, and the wedge plate 214 is driven to descend. The spring column 213 contracts at the same time, and the sliding connection between the slider 205 and the vertical plate 209 can prevent the panel 207 from shaking when moving up and down. The descent of the wedge plate 214 will squeeze and push the wedge plate 1 210. The wedge plate 1 210 extends outward from between the two partitions 202, thereby extending the length of the bracket 2 and increasing the contact area with the square tube, preventing the square tube from tilting and shaking. When 210 moves outward, the spring column 211 is blocked by the baffle 212 and shrinks. After the square tube is taken out, the sliding plate 204 is retracted toward the middle of the bracket 2 by the rebound of the spring column 211. The roller 206 facilitates the movement of the sliding plate 204. The friction ball 208 is used to increase the friction between the square tube and the bracket 2. The utility model can clamp square tubes of different sizes through the clamping plate 101 that can be adjusted up and down without replacing the caliper. The adaptability is wider, the cost is saved, and the square tube can be supported and clamped more tightly to prevent the square tube from tilting and shaking during punching, thereby ensuring the quality and accuracy of the square tube punching.

[0028] The working principle of the present invention is as follows: the square tube is placed on the top of the bracket 2, and the screw 107 is rotated to make it rise or retract from the inside of the support 103, and the screw 107 drives the connecting ring 106 and the clamping plate 101 to move up or down through the clamping ring 108, thereby adjusting the gap between the clamping plate 101 and the bracket 2, and the support plate 102 is slidably connected with the side plate 104 through the limiting rod 105, so that the angle of the clamping plate 101 can be limited when the screw 107 rotates; when the square tube is placed on the top of the bracket 2, it will press the panel 207 to descend, and the panel 207 will be embedded in the embedding groove 203. The top of the panel 207 is flush with the bracket 2, and drives the wedge plate 214 to descend, and the spring column 213 At the same time, the sliding connection between the slider 205 and the vertical plate 209 can prevent the panel 207 from shaking when moving up and down. The descent of the wedge plate 214 will squeeze and push the wedge plate 1 210. The wedge plate 1 210 extends outward from between the two partitions 202, thereby extending the length of the bracket 2, increasing the contact area with the square tube, and preventing the square tube from tilting and shaking. When the wedge plate 1 210 moves outward, the spring column 1 211 is blocked by the baffle 212 and shrinks. After the square tube is taken out, the sliding plate 204 is retracted toward the middle of the bracket 2 by the rebound of the spring column 1 211. The roller 206 facilitates the movement of the sliding plate 204. The friction ball 208 is used to increase the friction between the square tube and the bracket 2.
