DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and functions achieved by the present invention clearer and easier to understand, the technical solutions in the present invention are further described below in conjunction with the accompanying drawings and embodiments.

[0024] See also Figures 1 to 7 As shown, a button punching device comprises: a base 1, a column 2, a drilling machine and a clamping mechanism; the column 2 is vertically fixed at one end of the base 1, the drilling machine is arranged on the column 2 in a vertical direction, and the drilling machine is located directly above the clamping mechanism; the clamping mechanism comprises four hydraulic cylinders 31, the four hydraulic cylinders 31 are cross-distributed and fixed on the base 1, the piston rods of the four hydraulic cylinders 31 face inwards, and a first clamping block 32 is fixed on the piston rod, and the first clamping block 32 is away from the piston rod One side is an arc surface, and a notch 321 is provided on the arc surface. A second clamping block 33 is provided in the notch 321. A cavity 34 is provided in the first clamping block 32. A connecting rod 331 is fixedly connected to one side of the second clamping block 33. One end of the connecting rod 331 extends into the cavity 34 and is connected to the slider 35. A first spring 36 is sleeved on the connecting rod 331. The first spring 36 is located between the inner wall of the cavity 34 and the slider 35. A fixing component for fixing the second clamping block 33 is also provided on the first clamping block 32.

[0025] The column 2 serves to support and fix the drilling machine, which is convenient for drilling the buttons clamped by the clamping mechanism; the four hydraulic cylinders 31 are driven together, and the four hydraulic cylinders 31 are distributed in a cross shape to ensure that the buttons can be fixed from four different angles, thereby improving the stability of the fixation; a first spring 36 is arranged in the cavity 34, and under the elastic force of the first spring 36, the slider 35 will drive the connecting rod 331 to move away from the center of the area surrounded by the four hydraulic cylinders 31, so that the second clamping block 33 is located in the notch 321, and will not affect the first clamping block 32 when clamping the round button; the side of the second clamping block 33 away from the connecting rod 331 is a plane, and a fixing component is arranged, which can control the second clamping block 33 to extend out of the notch 321 and be fixed, thereby achieving the clamping and fixing of the square button. A first clamping block 32 and a second clamping block 33 are provided. When the four first clamping blocks 32 act together, the round buttons can be clamped and fixed and holes can be drilled. By controlling the second clamping block 33 to extend, the second clamping block 33 plays a role of clamping and fixing, and the square buttons can be clamped and fixed and holes can be drilled, so that the device can process two types of buttons, thereby improving applicability.

[0026] When in use, put the round button between the first clamping blocks 32, start the hydraulic cylinder 31, drive the first clamping block 32 to clamp the button, and then start the drilling machine to drill; when drilling a square button, control the second clamping block 33 to extend out of the notch 321 for clamping.

[0027] Furthermore, if Figures 4 to 7 As shown, the fixing assembly includes a straight rod 41, a cross rod 42 and a circular groove 43. An opening is set at the top of the cavity 34. The lower end of the straight rod 41 is fixed to the top of the slider 35. The upper end of the straight rod 41 passes through the opening and is fixed to the cross rod 42. The circular groove 43 is set on the upper surface of the first clamping block 32 and close to one end of the second clamping block 33. The lower part of the cross rod 42 is connected to the inner rod. The lower part of the inner rod is vertically slidable and provided with an outer cylinder 44 that can extend into the circular groove 43. A second spring 45 is connected between the outer cylinder 44 and the cross rod 42. When the lower end of the outer cylinder 44 contacts the surface of the first clamping block 32, the second spring 45 is compressed and an opening is set at the top of the cavity 34, so that the straight rod 41 can drive the slider 35 to slide, thereby extending the second clamping block 33. The movement of the straight rod 41 will drive the cross bar 42 to move, thereby driving the outer cylinder 44 to move. When the outer cylinder 44 moves to the top of the circular groove 43, under the action of the elastic force of the second spring 45, the outer cylinder 44 extends into the circular groove 43, thereby limiting the movement of the cross bar 42 and fixing the slider 35. At this time, the second clamping block 33 extends out of the notch 321 and can be used to clamp the square button.

[0028] Furthermore, in order to improve stability, Figure 5 and Figure 6 As shown, the lower end of the straight rod 41 is fixed to the middle of the slider 35, and the upper end of the straight rod 41 is fixed to the middle of the cross bar 42. The two ends of the cross bar 42 are symmetrically provided with inner rods. Two circular grooves 43 are also provided and symmetrically arranged on the first clamping block 32.

[0029] Furthermore, if Figure 1 and Figure 2 As shown, a first motor 5 is fixed to the top of the column 2, and a screw 6 is fixed to the output end of the first motor 5. A base plate is provided at the bottom of the column 2, and the lower end of the screw 6 is rotatably connected to the base plate. A nut 7 is threadedly connected to the screw 6, and one side of the nut 7 is fixed to the horizontal plate. The drilling machine is fixed to the horizontal plate, and a limit plate 71 is symmetrically arranged on the nut 7 and on both sides of the horizontal plate. A vertical slide groove 21 is provided on the column 2, and the limit plate 71 is slidably connected to the vertical slide groove 21 in the vertical direction. Because the vertical slide groove 21 is provided, the limit plate 71 on the nut 7 is slidably connected to the vertical slide groove 21 in the vertical direction, so that when the first motor 5 is started, the nut 7 can only move in the vertical direction, thereby driving the drilling machine to move downward to adjust the height, so as to facilitate drilling holes in the buttons below.

[0030] Furthermore, if Figure 1 and Figure 3 As shown, the drilling machine includes a second motor 81, a connection box 82, a driving gear 83, a driven gear 84 and a plurality of drill bits 85. The second motor 81 is fixed on the horizontal plate, and the connection box 82 is connected to the second motor 81. The output end of the second motor 81 is located in the connection box 82 and is coaxially fixed to the driving gear 83. The drill bit 85 is rotatably connected to the connection box 82. The upper end of the drill bit 85 is located in the connection box 82 and is coaxially fixed to the driven gear 84. The driving gear 83 is meshed with the driven gear 84. When the second motor 81 is started, the output shaft of the second motor 81 will drive the driving gear 83 to rotate, thereby driving the driven gear 84 meshed therewith to rotate. The rotation of the driven gear 84 drives the drill bit 85 to rotate for drilling. The number of drill bits 85 can be designed according to the number of holes to be drilled. In this embodiment, the number of drill bits 85 is two.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
