DETAILED DESCRIPTION

It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this embodiment can be combined with each other. The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1 to 6. The purpose of this embodiment is to achieve adjustable spacing of the punching machine without affecting the stability of the aluminum template when punching holes. In view of this, a punching device with adjustable spacing is provided, including a top plate 2 and a punching mechanism 4. Vertical side plates 3 are provided on both sides of the bottom of the top plate 2, and a T-shaped slide groove 201 is provided at the bottom of the top plate 2. Among them, the punching mechanism 4 includes a screw rod 42, and two punching members 41 are threadedly connected to the screw rod 42. The threads on the surfaces of the two sections of the screw rod 42 from the middle to the two sides are opposite. The two punching members 41 are respectively threadedly connected on different threads. When the screw rod 42 is rotated, the movement directions of the two punching members 41 will be opposite, so that the spacing of the holes can be adjusted.

The two ends of the screw rod 42 are rotatably connected to the two opposite sides of the two side panels 3, and one end of the screw rod 42 is rotatably extended to the outside of the side panel 3 and fixedly installed with a large gear 43, and a small gear 44 is meshed at the bottom of the large gear 43. At the same time, a first fixed rod 301 is rotatably installed on the outer side of the side panel 3, and the small gear 44 is coaxially fixedly connected to the first fixed rod 301. The end of the first fixed rod 301 extends to the outer side of the small gear 44 and is fixedly installed with a handle. The small gear 44 is driven to rotate by turning the handle, and the small gear 44 will drive the rotation of the large gear 43. Because the large gear 43 is fixedly connected to the end of the screw rod 42, the large gear 43 will drive the rotation of the screw rod 42, so that the two punching members 41 move closer to or away from each other, so as to achieve manual adjustment of the hole spacing. Among them, the small gear 44 drives the large gear 43, which can slow down the rotation of the screw rod 42, realize fine adjustment of the hole spacing, and make the spacing adjustment more accurate.

In order to fix the punching member 41 and prevent the punching member 41 from rotating with the screw rod 42, the punching member 41 includes a screw rod nut 411. The two screw rod nuts 411 are sleeved on the outside of the screw rod 42 and are threadedly connected. A slider 415 is fixedly installed on the top of each screw rod nut 411. The two sliders 415 are slidably inserted in the slide groove 201. In this way, when the screw rod 42 rotates, the two punching members 41 can only move horizontally along the screw rod 42.

In order to achieve the punching effect, a hydraulic cylinder 412 is fixed at the bottom of each screw nut 411, and a fixed block 413 is fixedly installed at the bottom of each hydraulic cylinder 412. An inner groove 4131 is opened inside the fixed block 413, and a first motor 4132 is fixed on the inner top wall of the inner groove 4131. The output shaft of the first motor 4132 is vertically downward and rotates to extend through the bottom outer side of the fixed block 413. A drilling head 414 is rotatably installed at the bottom of the fixed block 413, and the top of the drilling head 414 is coaxially connected to the output shaft of the first motor 4132. When the first motor 4132 and the hydraulic cylinder 412 are started, the hydraulic cylinder 412 will push the fixed block 413 and the drilling head 414 to move downward, and the first motor 4132 will drive the drilling head 414 to rotate, thereby achieving the punching effect.

Furthermore, a conveyor belt 1 is provided between the two side panels 3. In order to prevent the drilling head 414 from contacting the conveyor belt 1 when drilling downwards, heightening plates 101 are fixedly installed on both sides of the conveyor belt 1, and the height of the heightening plates 101 is lower than the height of the drilling head 414; at the same time, in order to prevent the aluminum template from shaking and causing deviations in the punched holes, limiting plates 102 are installed on the outer sides of the tops of the two heightening plates 101. When placing the aluminum template, the bottom surface of the end of the aluminum template is placed on the top surface of the heightening plate 101, and the end surface of the aluminum template is against the side of the limiting plate 102, thereby limiting the position of the aluminum template and preventing left and right deviations.

When the aluminum template moves to the bottom of the punching mechanism 4, it needs to be fixed in place so that it can be punched. Therefore, the rear sides of the two side panels 3 are rotatably installed with second fixed rods 302. At the same time, the rear sides of the two side panels 3 and the positions below the second fixed rods 302 are fixedly installed with support plates 303. The top surfaces of the two support plates 303 are fixed with second motors 5. The output shafts of the two second motors 5 are coaxially connected to the two second fixed rods 302 respectively, and the side walls of the two second fixed rods 302 are fixed with baffles 6. The two baffles 6 are symmetrically arranged. When the aluminum template moves to the bottom of the punching mechanism 4, the second motor 5 is started to rotate the baffle 6 to a horizontal state so that the baffle 6 can block the aluminum template. At the same time, since the aluminum template is only placed on the heightening plate 101, the aluminum template and the top surface of the heightening plate 101 are slidably fitted. Therefore, when the conveyor belt 1 drives the heightening plate 101 to rotate synchronously, the aluminum template will not move under the obstruction of the baffle 6; when the punching is completed, the second motor 5 is started to rotate the baffle 6 to a vertical state.

Among them, when the baffle 6 rotates to a horizontal state, the top surface of the limit plate 102 is tangent to the side surface of the baffle 6, and the operation of the conveyor belt 1 is not affected when the position of the aluminum template is fixed. At the same time, in order to reduce the friction between the aluminum template and the height-increasing plate 101, a plurality of ball bearings are provided on the contact surface between the height-increasing plate 101 and the aluminum template.

It should be added that the height-increasing plate 101 and the limit plate 102 are both composed of a plurality of plate sections connected end to end by connecting lines. Such a configuration can ensure that the height-increasing plate 101 and the limit plate 102 rotate with the rotation of the conveyor belt 1 .

When the utility model is used in practice, the handle on the first fixing rod 301 is first rotated to adjust the spacing between the two punching members 41 to the required position, and then the aluminum template to be punched is placed on the height-increasing plate 101. When it moves to the front below the punching mechanism 4, the second motor 5 is started to rotate the baffle 6 to a horizontal state, and the aluminum template is blocked by the baffle 6. Then, the first motor 4132 and the hydraulic cylinder 412 are started, and the drilling head 414 will rotate and move downward, thereby realizing the punching function. When the punching is completed, the second motor 5 is started again to rotate the baffle 6 to a vertical state, and the punched aluminum template will be taken away by the conveyor belt 1.
