Technical Field
[0001] The utility model relates to the technical field of processing tooling, in particular to a drilling auxiliary device. Background Art
[0002] When manufacturing furniture, in order to vertically assemble furniture connectors together, it is necessary to drill holes on the side of the furniture connectors. The pistol drill has the characteristics of being flexible to use and can be applied to various occasions. Therefore, manufacturers usually use a pistol drill to drill holes in furniture connectors. However, the drilling quality completely depends on the skill level of the operator, and the quality and position of the drilled holes cannot be guaranteed. Summary of the Utility Model
[0003] In order to overcome the above-mentioned defects existing in the prior art, the utility model provides a drilling auxiliary device.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a drilling auxiliary device, including a bidirectional screw. Two groups of limiting pieces are fixedly installed in the middle of the bidirectional screw. A positioning plate is movably installed between the two groups of limiting pieces. A guiding rod is fixedly installed on the positioning plate. Clamping plates are movably installed at the left and right ends of the guiding rod. Nuts matching the bidirectional screw are fixedly installed on the side walls of the clamping plates far away from the positioning plate. Guide cylinders are arranged at the front and rear ends of the positioning plate, and the guide cylinders are used to guide the drilling direction of the drill bit.
[0005] Further, clamping plates are fixedly installed at the front and rear ends of the positioning plate. A limiting platform is fixedly installed at the bottom of the clamping plate. Installation grooves matching the clamping plates are formed on the guide cylinders, and the installation grooves are of a "T" - shaped structure.
[0006] Further, limiting stop pieces are fixedly installed at both ends of the guiding rod.
[0007] Further, protective pads are fixedly installed on the adjacent side walls of the two groups of clamping plates, and the protective pads are made of rubber.
[0008] Further, handles are fixedly installed at both ends of the bidirectional screw.
[0009] The beneficial effect of the utility model is that in the design scheme of the utility model, through the design that a positioning plate is fixedly installed in the middle of the bidirectional screw, the clamping plates are connected to the bidirectional screw through nuts. When drilling, the guide cylinders are oriented towards the inner side wall of the furniture connector. Then, the bidirectional screw is rotated through the handle. Under the cooperation of the bidirectional screw and the nuts, the clamping plates move towards the positioning plate along the guiding rod, and the side wall of the furniture connector is clamped by the clamping plates, thereby fixing the tooling on the wooden board and aligning the guide cylinders with the thickness center of the clamped object. Then, the drill bit of the electric hand drill is inserted into the guide cylinders, and the forward direction of the drill bit is guided by the guide cylinders, so as to avoid the situation that the drill bit deviates, and further ensure the quality and position of the drilled holes.

[0016] In order to more clearly illustrate the technical solutions of the present utility model, the present utility model will be further described below in conjunction with the drawings. Obviously, the drawings described below are only one embodiment of the present utility model. For those of ordinary skill in the art, without creative efforts, other embodiments obtained based on this drawing and embodiment all fall within the protection scope of the present utility model.
[0017] According to Figures 1-4 as shown, a drilling auxiliary device includes a bi-directional screw 1. Two groups of limiting pieces 11 are welded in the middle of the bi-directional screw 1. A positioning plate 2 is movably installed between the two groups of limiting pieces 11. A guide rod 4 is welded on the positioning plate 2. Clamping plates 5 are movably installed at the left and right ends of the guide rod 4. Nuts 6 matching the bi-directional screw 1 are welded on the side walls of the clamping plates 5 away from the positioning plate 2. Guide cylinders 7 are arranged at the front and rear ends of the positioning plate 2. The guide cylinders 7 are used to guide the drilling direction of the drill bit.
[0018] In this embodiment, clamping plates 21 are welded at the front and rear ends of the positioning plate 2. Limiting platforms 3 are welded at the bottoms of the clamping plates 21. Installation grooves 71 matching the clamping plates 21 are formed on the guide cylinders 7. The installation grooves 71 are of a "T" - shaped structure. The tops of the guide cylinders 7 are abutted against the side walls of the wooden board and are limited by the limiting platforms 3, thereby fixing the guide cylinders 7.
[0019] In this embodiment, limit flanges 8 are welded to both ends of the guide rod 4. The two ends of the guide rod 4 are connected to each other through the limit flanges 8, which improves the rigidity of the guide rod 4. Moreover, the clamping plate 5 is limited by the limit flanges 8 to prevent the clamping plate 5 from detaching from the guide rod 4.
[0020] In this embodiment, protective pads 9 are fixedly installed on the adjacent side walls of the two groups of clamping plates 5. The protective pads 9 are made of rubber. When fixing the tooling on the wooden board, the surface of the wooden board is protected by the protective pads 9 to prevent the surface of the wooden board from being scratched.
[0021] In this embodiment, both ends of the bidirectional screw 1 pass through the limit flanges 8. A handle 10 is welded to the left end of the bidirectional screw 1. When fixing the tooling, the user holds both sides of the positioning plate 2 and rotates the bidirectional screw 1 through the handle 10.
[0022] When the present utility model is in use, according to the drill bit diameter of the electric drill, a guide cylinder 7 that matches it is selected. The installation groove 71 of the guide cylinder 7 is aligned with the clamping plate 21 and inserted together. Then the guide cylinder 7 faces the inner side wall of the furniture connector. Then, the bidirectional screw 1 is rotated through the handle 10. Under the cooperation of the bidirectional screw 1 and the nut 6, the clamping plate 5 moves along the guide rod 4 towards the positioning plate 2, and the side wall of the furniture connector is clamped by the clamping plate 5, thereby fixing the tooling on the furniture connector and aligning the guide cylinder with the thickness center of the object to be clamped. Then, the drill bit of the electric drill is inserted into the guide cylinder 7, and the advancing direction of the drill bit is guided by the guide cylinder 7, thereby avoiding the situation that the drill bit deviates, and further ensuring the quality and position of the drilling.
[0023] The above embodiments are only exemplary embodiments of the present utility model and are not used to limit the present utility model. The protection scope of the present utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present utility model within the essence and protection scope of the present utility model, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present utility model.
