Referring to fig. 2 and 3, the fixing assembly 4 includes a mounting plate 41 fixedly connected to the piston rod of the punching cylinder, an expansion link 42 fixedly connected to one side of the mounting plate 41 facing the workbench 13, a supporting plate 43 fixedly connected to one end of the expansion link 42 far away from the mounting plate 41, and a spring 44 sleeved on the expansion link 42, wherein the spring 44 is located between the mounting plate 41 and the supporting plate 43, four expansion links 42 are provided, and two adjacent expansion links 42 are distributed at 90 degrees along the axis of the punching die head 31. Meanwhile, the abutting plate 43 is provided with a relief hole 431 through which the punching die 31 passes. Normally, the abutting plate 43 is located below the punching die head 31, when the punching cylinder 3 is started to drive the punching die head 31 to move downwards, the abutting plate 43 is firstly contacted with the wood board placed on the workbench 13, then the piston rod of the punching cylinder 3 continues to move downwards, the abutting plate 43 compresses the spring 44, and the spring 44 gives the abutting plate 43 a force towards the wood board at the moment, so that the wood board is clamped between the abutting plate 43 and the workbench 13. The punching die head 31 can easily penetrate through the avoiding hole 431 and punch the wood board.

In order to facilitate the workers to place the wood board on the workbench 13, the position to be punched is just under the punching die head 31, and the positioning assembly 5 is further arranged on the workbench 13 to realize the positioning of the wood board.

Referring to fig. 2 and 3, the positioning assembly 5 includes a limiting bar 51 slidably connected to the worktable 13, a first sliding block 511 having a T-shaped cross section is fixedly connected to one side of the limiting bar 51 facing the worktable 13, and a first sliding slot 512 for the first sliding block 511 to slide through is formed through two opposite sides of the worktable 13, so that the position of the limiting bar 51 on the worktable 13 can be adjusted by adjusting the relative position of the first sliding block 511 in the first sliding slot 512. Meanwhile, in order to fix the relative position of the first sliding block 511 in the first sliding groove 512, a first positioning bolt 513 screwed with the first sliding block 511 penetrates through the first sliding groove 512, and the first positioning bolt 513 abuts against the upper surface of the workbench 13.

The positioning assembly 5 further comprises two limiting blocks 52 connected to one side of the limiting strip 51 far away from the bracket 12 in a sliding manner, and the limiting strip 51 and the two limiting blocks 52 together form a cavity for placing the wood board. A second slider 521 with a T-shaped cross section is fixedly connected to one end of each limiting block 52 facing the limiting strip 51, a second sliding slot 522 for allowing the second slider 521 to slide is formed through two ends of the limiting strip 51, a kidney-shaped slot 524 (refer to fig. 1) communicated with the second sliding slot 522 is formed in one side of the limiting strip 51 far away from the limiting block 52, a second positioning bolt 523 in threaded connection with the second slider 521 is arranged in the kidney-shaped slot 524 in a penetrating manner, the second positioning bolt 523 abuts against one side of the limiting strip 51 far away from the limiting block 52, the relative position of the limiting block 52 relative to the limiting strip 51 can be fixed through the second positioning bolt 523, and the limiting block 52 is prevented from sliding on the limiting strip 51 under the action of external force.

Preferably, in order to facilitate the worker to screw the first positioning bolt 513 and the second positioning bolt 523, a butterfly bolt is used for each of the first positioning bolt 513 and the second positioning bolt 523.

Referring to fig. 2 and 3, a storage box 6 for collecting wood chips is further placed on the bottom plate 11, and a guide pipe 61 is communicated between the storage box 6 and the through hole 131, wherein the guide pipe 61 is a hose. An auxiliary pipe 62 communicating with the through hole 131 is fixed to the lower surface of the table 13, an attachment pipe 63 threadedly coupled to the auxiliary pipe 62 is fixed to one end of the guide pipe 61, and the guide pipe 61 and the through hole 131 can be communicated with each other through the auxiliary pipe 62 and the attachment pipe 63. During the installation, directly will install pipe 63 threaded connection on auxiliary tube 62, then with the one end that mounting tube 63 was kept away from to stand pipe 61 insert in receiver 6 can.

Preferably, in order to prevent the wood chips in the guide pipe 61 from spilling out of the box opening of the storage box 6 when the wood chips fall into the storage box 6, a cover 64 is further inserted into the box opening of the storage box 6, and the cover 64 is provided with a mounting hole 641 through which the guide pipe 61 passes. At the same time, a stopper 65 is fixed to the inner wall of the storage case 6, and when the cap 64 is inserted into the storage case 6, the bottom surface of the cap 64 abuts against the stopper 65, so that the relative position of the cap 64 and the storage case 6 can be restricted. When the saw-dust in receiver 6 is too much, directly take down lid 64 from receiver 6, then can with the saw-dust in receiver 6 pour out.

In order to facilitate the worker to remove the cover 64 from the storage case 6, a handle 66 is also fixed to the cover 64.

In summary, when the wood board needs to be punched, the wood board to be punched is first placed on the worktable 13 and the position to be punched is aligned with the punching die 31. Then adjust spacing 51 and plank one end butt, fix the relative position of spacing 51 on workstation 13 through first positioning bolt 513, then slide the position of stopper 52 on spacing 51, make the relative one side butt of two stoppers 52 at the both sides of plank, and fix the relative position of stopper 52 on spacing 51 through second positioning bolt 523, the regulation work of fixed subassembly 4 has just so far been accomplished, it can directly to place the plank that needs to punch a hole in the holding that stopper 52 and spacing 51 formed during staff's subsequent operation. Subsequently, the punching cylinder 3 is started, the piston rod of the punching cylinder 3 drives the punching die head 31 to move downwards, so that the abutting plate 43 abuts against the upper surface of the wood board, the wood board is fixed between the abutting plate 43 and the workbench 13, then the punching die head 31 also penetrates through the avoiding hole 431 and punches the wood board, and wood chips generated by punching reach the guide pipe 61 through the through hole 131 and finally fall into the storage box 6. The perforating cylinder 3 is then operated to retract the piston rod, which returns the abutment plate 43 under the action of the spring 44, again to the position below the punching die 31. The worker can directly take down the board after punching and put the board to be punched, and the steps are sequentially circulated.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
