Description

Sleeve structure with pawl

This creation relates to a tool socket, especially a socket structure with a pawl.

Generally, power machines with tools, such as integrated center cutting machines, lathes, drilling machines, etc., need to use a collet to clamp the tools. As shown in Fig. 5, the conventional collet 30 clamps a tool through a tightening nut 31, and then is activated by the power shaft of the working machine to drive the collet and the tool to rotate synchronously for processing Operation.

When the above-mentioned collet 30 wants to replace the tool and the tightening nut 31 is tightened or loosened, a special tool 32 is required to be clamped outside the tightening nut 31, and then force is applied to rotate the tightening nut 31, To achieve the replacement and tightening of the tool, the tightening nut 31 is provided with a plurality of clamping grooves 311 at equal distances on the outer edge, and the special tool 32 has a C-shaped sleeve 321, and then the C-shaped sleeve is The 321 is protruded with a plurality of claws 322 to be engaged with the locking grooves 311 , and accordingly, the special tool 32 is further engaged with the tightening nut 31 and the actuator is screwed.

However, in the conventional special tool 32, a C-shaped sleeve 321 is clamped to the outside of the tightening nut 31 and rotated with force. The C-shaped sleeve 321 has a lateral opening to form a weak edge, causing the C-shaped sleeve 321 to form a weak edge. The barrel 321 is easily deformed from the opening under the turning action, and the screwing action cannot be performed reliably, which causes inconvenience in use; in addition, the slot 311 of the conventional tightening nut 31 and the claws 322 of the special tool 32 are connected with each other. In the form of square columns, it is easy to collide and interfere with each other, and it lacks the practicability of quick fitting, and it is often The damage caused by the collision will further affect the tightness of the engagement between the special tool 32 and the tightening nut 31, thereby losing the basic disassembly and assembly effect, and it is necessary to improve.

In view of this, the creator has been engaged in the manufacturing, development and design of related products for many years, aiming at the above-mentioned goals, after detailed design and careful evaluation, and finally got a practical creation.

The technical problem to be solved by this creation is to provide a sleeve structure with detent pawls in view of the above-mentioned deficiencies in the prior art.

The above-mentioned sleeve structure with pawls includes a sleeve body, the sleeve body has a fitting section and a non-cylindrical joining section, the outer diameter of the fitting section is larger than the outer diameter of the joining section, and The inner diameters of the nesting section and the coupling section are hollow and communicated. The inner diameter of the nesting section is equidistantly provided with a plurality of pawl protrusions extending along the axial direction, and the pawl protrusions are adjacent to the nesting section. One end of the segment port is tapered from the inside to the outside to form a slope.

Preferably, the fitting section is an annular body, and the inner diameter is shaped like a circular hole.

Preferably, the inner diameter of the fitting section is larger than the inner diameter of the coupling section.

Compared with the effect of the prior art: the sleeve system is used to disassemble and assemble the collet structure, and the annular design of the sleeve section helps to strengthen the structural strength of the sleeve body during disassembly and assembly, and the sleeve The collet system can have a variety of dimensional changes according to the size of the collet, which further improves the applicability and practicability of disassembly and assembly of the collet.

In order to enable your reviewers to have a further understanding and understanding of the purpose, features and effects of this creation, please follow the [Simple Description of the Drawing] as follows:

First, as shown in Figures 1 and 2, a sleeve structure with pawls includes a sleeve body 10, the sleeve body 10 has an engaging section 11 and a non-cylindrical joint Section 12, the fitting section 11 is a ring body, and the outer diameter of the fitting section 11 is larger than the outer diameter of the coupling section 12, the inner diameter of the fitting section 11 and the coupling section 12 are hollow and The inner diameter of the fitting section 11 is formed into a circular hole shape, and a plurality of pawl protrusions 111 extending along the axial direction are arranged at equal intervals. An inclined surface 112 is formed by gradually thinning from the inside to the outside, and the inner diameter of the fitting section 11 is larger than the inner diameter of the coupling section 12 .

The actual use state of its structure is shown in Figures 3 and 4. The sleeve body 10 is mounted on a tool handle (not shown in the figure) with a joint section 12. The tool handle has a The non-circular hole-shaped sleeve hole of the combination section 12, the sleeve hole is a one-way ratchet, a two-way ratchet or a general fit sleeve. This sleeve system is used for locking and loosening cutting tools such as drilling tools, milling cutters, The collet 20 of the tool A such as a tapping knife, the collet 20 is relatively twisted or loosened by a tightening nut 21 to achieve the tightening fixation or loosening of the tool A. The outer periphery of the tightening nut 21 is provided with A plurality of snap-fit grooves 211, the fitting section 11 is sheathed outside the tightening nut 21, and the hollow portion formed by the fitting section 11 and the combining section 12 can accommodate the cutter A, and then The pawl protrusions 111 are relatively engaged with the engaging grooves 211 , so that the sleeve section 11 can be quickly sleeved outside the tightening nut, and the tool handle can be rotated and rotated. The tightening nut 21 is screwed clockwise or unscrewed counterclockwise, so as to achieve the purpose of quickly dismounting and fixing the tool A, and further improving the convenience of using and replacing the tool A.

In addition, the engaging groove 211 on the outer periphery of the tightening nut 21 forms a beveled groove body with an outer depth and an inner shallower groove. The groove 211 is slid into the positioning according to the trend, so as to achieve the purpose of accurate and stable fitting.
