Description

Technical Field

[0001] The utility model belongs to the technical field of tool handles, and in particular relates to a deburring floating tool handle. Background Art

[0002] After metal parts are cast, burrs often appear. In order to ensure the normal progress of subsequent processes, it is necessary to deal with the residues. Currently, deburring floating cutter heads are commonly used for deburring, and the cutter heads are installed through special tool holders.

[0003] At present, the floating tool handle is mainly installed by means of threads in its own assembly, and needs to be tightened or unscrewed manually. Once the threaded connection is rotten or rusted, it is difficult to open it manually. Since the locking position is a smooth curved surface, it is also difficult to open it with the assistance of external mechanical equipment. Therefore, there are great limitations in actual use and there is room for improvement. Utility Model Content

[0004] The utility model aims to provide a floating tool handle for deburring, so as to solve the problem that the existing floating tool handle mentioned in the background technology is inconvenient to operate during assembly.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a deburring floating tool handle, comprising a handle body, which is connected to a three-jaw chuck on a machine tool during use; a connecting screw sleeve, which has a thread on its outer surface, one end of which is screwed into the handle body and the other end is outside the handle body; it also includes a locking sleeve, which has a thread inside and is screwed into the other end of the connecting screw sleeve. A structure for tightening the head should also be provided inside the locking sleeve, specifically a collet. Since this structure is irrelevant to the improvement point, it is not shown in the figure; and an adjustment part, which is integrally formed at the rear part of the locking sleeve and has an overall longitudinal cross-section of a regular prism. The threads in the locking sleeve are all concentrated in the area of ​​the adjustment part, and the adjustment part is threadedly connected to the connecting screw sleeve; at least one oil hole is provided and is opened on the adjustment part. The oil hole and the inner wall of the adjustment part are in a through shape. When rust exists at the connection between the connecting screw sleeve and the adjustment part, lubricating oil can be injected from the oil hole to achieve the function of auxiliary lubrication and facilitate later opening.

[0006] Preferably, the longitudinal section of the adjusting portion is a regular hexagon, and each corner of the adjusting portion is rounded to avoid the situation where large wear and tear would occur if no rounded corners are provided.

[0007] Preferably, the length of the adjusting portion is greater than half of the total length of the locking sleeve, and the longitudinal section of the locking sleeve is a circumscribed circle of the longitudinal section of the adjusting portion.

[0008] Preferably, an inner groove is provided on the end surface of the adjusting portion, the oil-permeable hole is within the area of ​​the oil-permeable hole, a silicone sheet is placed inside the inner groove, a cross groove is provided on the silicone sheet, and the cross groove coincides with the projection area of ​​the oil-permeable hole. When not in use, the oil-permeable hole can be protected by the silicone sheet, and when in use, a tubular object with lubricating oil can be inserted into the oil-permeable hole and the cross groove can be pushed open to achieve the purpose of injecting lubricating oil.

[0009] Preferably, the thickness of the silicone sheet is less than or equal to the inner depth of the inner groove, and the number of the inner grooves is equal to the number of the oil-permeable holes.

[0010] Preferably, a collet is installed in the internal interference fit of the connecting screw sleeve, one end of the collet extends toward the end face of the locking sleeve, and the end faces of the two are flush, and the cutter head is installed in the collet to achieve fixation. Since this structure is an existing structure and has nothing to do with the improvement points, it will not be further described here.

[0011] Preferably, the handle body is in the shape of a stepped shaft, and the axes of the handle body and the locking sleeve are on the same horizontal line.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] Through the designed adjustment part and oil hole, the threaded connection of the tool handle can be lubricated, which is convenient for opening when the threaded connection is rusted. At the same time, it can also provide a fulcrum for external mechanical equipment to achieve the function of auxiliary opening. The design of this structure is more convenient for the disassembly and assembly of the floating tool handle, and improves the shortcomings of the existing structure in use.
