[0041] The mounting block 3 is horizontally slidably connected to the mounting seat 2 along the width direction of the placement table 1, the mounting seat 2 is provided with a first linear module 6 for driving the mounting block 3 to slide along the width direction of the placement table 1, and the drill bit 4 is slidably connected to the mounting block 3 along the vertical direction. Figure 1 and Figure 3The installation groove 8 is arranged in the placing table 1, and the top of the placing table 1 is fixedly provided with a plurality of placing plates 9 which are horizontally arranged along the length direction of the placing table 1, so as to facilitate the placing of the workpiece. The adjacent two placing plates 9 are provided with a clearance hole 10 which is in communication with the installation groove 8, so that when the workpiece is placed at the hole opening of the clearance hole 10, the through hole machining of the workpiece can be realized through the vertical movement of the drill bit 4.

[0042] With reference to Figure 2 and Figure 4 The placing table 1 is provided with a clamping mechanism and a fine adjustment mechanism. The clamping mechanism comprises a clamping seat 11, a clamping plate 12, a first movement assembly and a second movement assembly. The first movement assembly comprises a first movement lead screw 13, a first motor 14 and a first guide rod 15. The first movement lead screw 13 is horizontally rotatably arranged on the placing table 1 and extends along the length direction of the placing table 1. The first movement lead screw 13 is arranged in the clamping seat 11 and threadedly cooperates with the clamping seat 11. The first guide rod 15 is horizontally fixedly arranged on the placing table 1 and is arranged in parallel with the first movement lead screw 13. The first movement lead screw 13 and the first guide rod 15 are respectively close to the two sides of the placing table 1 in the width direction. The first guide rod 15 is arranged in the clamping seat 11 and slidably cooperates with the clamping seat 11. The bottom of the clamping seat 11 is located on the groove wall of the installation groove 8 which is away from the groove opening and slidably cooperates with the placing table 1. When the first movement lead screw 13 rotates, the clamping seat 11 slides along the length direction of the placing table 1.

The guide rod 21 is arranged in parallel with the bidirectional screw rod 20, and the two ends of the guide rod 21 are respectively fixedly connected to the two fixing parts 112. The guide rod 21 is arranged in the two clamping plates 12 and is slidably connected with the two clamping plates 12, so that when the bidirectional screw rod 20 rotates, the two clamping plates 12 move towards each other or away from each other under the limiting action of the guide rod 21.

[0045] With reference to the above Figure 3 and Figure 4 , the second motor 19 is fixedly arranged on the top of the bearing part 111 and close to the middle part of the bidirectional screw rod 20. The output end of the second motor 19 is fixedly connected with a driving worm 22. The bidirectional screw rod 20 is coaxially fixedly connected with a driving worm wheel 23. The driving worm wheel 23 is engaged with the driving worm 22, so that when the second motor 19 drives the output end to rotate, the bidirectional screw rod 20 rotates at the same time. The bearing part 111 is provided with a protective cover 24 which covers the second motor 19, so as to protect the second motor 19 and ensure the stability of the second motor 19 during operation.

[0046] With reference to the above Figure 4 , the clamping plate 12 comprises a bearing seat 121 and a mounting part 122. The mounting part 122 is oppositely arranged and fixedly arranged on the bearing seat 121. When the workpiece is placed on the placing table 1, the two clamping plates 12 move towards each other and abut against the two sides of the workpiece. The two mounting parts 122 are respectively arranged on the two sides of the workpiece in the vertical direction. The two mounting parts 122 are sequentially arranged from top to bottom as a first mounting part 1221 and a second mounting part 1222. The first mounting part 1221 is provided with a lifting plate 25 and a lifting driving part.

[0047] With reference to the above Figure 4 , the lifting driving part comprises a lifting cylinder 26. The lifting cylinder 26 is vertically arranged on the top of the first mounting part 1221. The piston rod of the lifting cylinder 26 is arranged in the first mounting part 1221 and slidably connected with the first mounting part 1221. The lifting plate 25 is fixedly arranged on the piston rod of the lifting cylinder 26, so that when the lifting cylinder 26 drives the piston rod to move, the lifting plate 25 can abut against the top of the workpiece.

The bearing worm 30 is fixedly arranged at the output end of the bearing motor 28 and is in engagement with the bearing worm wheel 29. The bearing guide rod 32 is vertically fixedly arranged at the bottom of the bearing plate 27. The bearing guide rod 32 penetrates through the clamping plate 12 and is in sliding cooperation with the clamping plate 12. When the bearing motor 28 drives the bearing worm 30 to rotate, the bearing lead screw 31 drives the bearing plate 27 to move along the vertical direction due to the threaded cooperation with the bearing worm wheel 29 and the limiting action of the bearing guide rod 32, so that the stable bearing and pressing of the bottom of the workpiece can be realized.

[0049] With reference to Figure 4 and Figure 5 The fine adjustment mechanism comprises a fine adjustment rod 33, a driving rod 34, a connecting rod 35 and a fine adjustment motor 36. Each of the fine adjustment rod 33 and the driving rod 34 is provided with a plurality of groups, and each group is provided with two fine adjustment rods 33. The two fine adjustment rods 33 in each group penetrate through one of the placement plates 9 along the vertical direction and are in sliding cooperation with the placement plate 9. The two fine adjustment rods 33 are respectively arranged close to the two ends of the placement plate 9 along the length direction. When one of the fine adjustment rods 33 slides upward along the vertical direction, the adjustment of the horizontal degree of the workpiece, i.e. the civil air defense door, in one direction on the placement table 1 can be realized, which has strong applicability. When the workpiece is obliquely drilled and the clamping plate 12 clamps and fixes the workpiece, the fine adjustment rod 33 can further support the workpiece, so as to facilitate the stability of the workpiece during the drilling process. The top of the fine adjustment rod 33 is arranged in a circular arc transition, so that when the fine adjustment rod 33 supports the workpiece, the scratch caused by the friction between the fine adjustment rod 33 and the workpiece at the corner of the fine adjustment rod 33 is not easy to occur.

[0050] With reference to Figure 4 and Figure 5The top of the driving rod 34 is provided with two sliding grooves 37 extending along the length direction of the driving rod 34 and arranged near the two ends of the driving rod 34 respectively, and each sliding groove 37 extends to the two sides of the driving rod 34 in the horizontal direction. The bottom of the fine adjustment rod 33 is rotatably connected with a horizontal rotating roller 38, each rotating roller 38 is located in each sliding groove 37 and rotatably connected with each sliding groove 37, and each rotating roller 38 can slide along the extension direction of the sliding groove 37. In order to ensure the stability of the rotating roller 38 when sliding in the sliding groove 37, the two ends of the rotating roller 38 are fixedly connected with limiting portions 39, and the two limiting portions 39 abut against the two sides of the driving rod 34 in the horizontal direction, so as to limit the movement of the rotating roller 38.

[0051] With reference to Figure 3 and Figure 5 The connecting rod 35 is horizontally rotatably installed on the placing table 1, the connecting rod 35 is sequentially arranged in the middle part of each driving rod 34 in the length direction and fixedly connected with each driving rod 34, and the top of each fine adjustment rod 33 is flush with the top of the placing plate 9 when the driving rod 34 is in the horizontal state. When the connecting rod 35 drives the driving rod 34 to rotate around the axis thereof, the rotating shaft slides in the sliding groove 37, one of the fine adjustment rods 33 moves upward in the vertical direction, and the other fine adjustment rod 33 moves downward in the vertical direction. The fine adjustment motor 36 is horizontally fixedly installed on the placing table 1, the output end of the fine adjustment motor 36 is fixedly installed with a fine adjustment worm 40, the connecting rod 35 is coaxially fixedly connected with a fine adjustment worm wheel 41, and the fine adjustment worm 40 is meshed with the fine adjustment worm wheel 41, so that the fine adjustment motor 36 drives the connecting rod 35 to rotate, and the self-locking effect between the fine adjustment worm 40 and the fine adjustment worm wheel 41 is beneficial to ensure the stability of the position of the connecting rod 35 after rotation.

[0052] The implementation principle of the drilling equipment for the civil air defense engineering is as follows: when the workpiece, i.e. the civil air defense door, needs to be drilled, first, the civil air defense door is placed on the top of each placing plate 9 of the placing table 1, then the horizontal degree of the civil air defense door placed on the placing table 1 is adjusted through the vertical movement of the fine adjustment rod 33, or the two clamping plates 12 are directly driven to move towards each other by the second motor 19 to realize the clamping and fixing of the two sides of the civil air defense door, and the drilling of the corresponding position of the civil air defense door to the relief hole 10 is realized by the drill bit 4 of the drilling equipment. When the area of the civil air defense door which is not opposite to the relief hole 10 needs to be processed into a through hole, the clamping seat 11 is driven to move in the horizontal direction by the rotation of the first movement screw rod 13, so that the civil air defense door clamped by the two clamping plates 12 moves together, and then the area to be drilled of the civil air defense door placed on the placing table 1 is moved to the area corresponding to the relief hole 10, and then the civil air defense door is processed by the drill bit. When the civil air defense door is drilled, the worker does not need to manually move the civil air defense door, so that the drilling operation of the civil air defense door is simple, and the processing efficiency of the civil air defense door is ensured.

[0053] When the workpiece, i.e., the civil defense door, is drilled, the vertical movement of the fine adjustment rod 33 can level the civil defense door, thereby facilitating the guarantee of the levelness of the position of the civil defense door during drilling, and further guaranteeing the processing quality of the civil defense door. In addition, driving the bearing plate 27 to move towards the direction of the material ejecting plate 25 by the bearing motor 28 and driving the material ejecting plate 25 to move towards the direction of the bearing plate 27 by the material ejecting cylinder 26 facilitates the further clamping and fixing of the civil defense door, thereby further guaranteeing the stability of the position of the civil defense door during drilling. The two-stage vertical movement of the bearing plate 27 and the material ejecting plate 25 can also obliquely clamp the civil defense door placed on the placing table 1, thereby facilitating the drilling of the civil defense door at different angles, and having strong applicability; when the civil defense door is obliquely drilled, the fine adjustment rod 33 can further support the civil defense door through vertical movement when the clamping plate 12 clamps and fixes the civil defense door, thereby facilitating the full guarantee of the stability of the civil defense door during drilling.

[0054] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made on the basis of the structure, shape, principle of the present application shall be encompassed within the protection scope of the present application.
