Abstract
Description
Technical Field
[0001] The utility model relates to the field of fixtures, in particular to a chip blowing tool for blind holes in a rear panel of a door lock. Background Art
[0002] Currently, after tapping the mounting holes on the rear panel of a door lock, blind holes are created, often becoming trapped with aluminum chips. Coolant in the blind holes also makes it easier for the chips to stick to them. If these chips are not removed, they can affect subsequent installation. The current practice is for engineers to blow out the chips one by one using a high-pressure air gun after machining. This method is inefficient and prone to omissions, which can affect subsequent assembly. Summary of the Invention
[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides a chip blowing tool for the blind hole of the rear panel of a door lock, which has a simple structure and significantly improves the chip blowing efficiency.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A blind hole chip blowing tool for the rear panel of a door lock is characterized in that it includes a positioning plate, a first positioning column and a second positioning column are provided on the top surface of the positioning plate, the top surface of the positioning plate has a plurality of transversely arranged first grooves, the first grooves have a plurality of blowing ports, the top surface of the positioning plate has a raised portion, and the raised portion has a transverse avoidance groove and a longitudinal avoidance groove.
[0006] Furthermore, support feet are provided at the four corners of the bottom surface of the positioning plate.
[0007] Furthermore, the depth of the first groove is greater than the height of the protrusion, and the first groove passes through the positioning plate in a transverse direction.
[0008] Furthermore, the air outlet corresponds to the position of the blind hole on the rear panel of the door lock.
[0009] The beneficial effects of the utility model include: simple structure, ability to blow slag from multiple blind holes at the same time, improved slag blowing efficiency, fallen residues can be blown out from both ends of the first groove, good slag blowing effect, the positioning plate accurately positions the workpiece, can ensure that each blind hole can be cleaned, and good support effect for the workpiece. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a structural diagram of the present utility model. DETAILED DESCRIPTION
[0011] The present invention will be described in further detail below with reference to specific embodiments and accompanying drawings.
[0012] A kind of Figure 1 The illustrated blind hole chip blowing tool for the door lock rear panel includes a positioning plate 1, with first and second positioning posts 2 and 3 disposed on its top surface. The top surface of the positioning plate 1 has multiple transversely arranged first grooves 4, each containing multiple air ports 5. The air ports 5 correspond to the blind holes on the door lock rear panel. During the chip blowing operation, the door lock rear panel is precisely positioned relative to the first and second positioning posts 2 and 3 through the door lock hole and the mounting hole. This ensures that the air ports 5 precisely align with the blind holes. The bottom surface of the air ports 5 has a high-pressure air connection port. The top surface of the positioning plate 1 has a raised portion 6, which is provided with a transverse avoidance groove 7 and a longitudinal avoidance groove 8. This ensures that the door lock rear panel fits perfectly onto the positioning plate 1, preventing blown debris from entering holes in other areas. The depth of the first groove 4 is greater than the height of the raised portion 6 and extends transversely through the positioning plate 1. Dropped debris can be blown out from both ends of the first groove, providing effective chip blowing.
[0013] Support feet 9 are provided at the four corners of the bottom surface of the positioning plate 1 to increase the height of the positioning plate 1 and facilitate the connection of the air pipe to the positioning plate 1.
[0014] The above is a detailed introduction to the technical solutions provided by the embodiments of the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, according to the embodiments of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the contents of this specification should not be understood as limiting the present invention.
