Embodiment 1

[0034] (overall structure of the tool)

[0035] Figure 3 ~ Figure 5 It shows an embodiment of the insertion tool 1 for the endless helical coil insert of the present invention. According to the present embodiment, the tailless helical coil insertion tool 1 is an electric type, and has a driving mechanism part 2 and a coil insertion mechanism part 3 .

[0036] The frame body 4 of the drive mechanism part 2 doubles as a tool grip part, and is shaped so that an operator can hold it with one hand and perform work. A reversible electric motor M constituting the drive mechanism section 2 and capable of rotationally driving in the forward direction and the reverse direction is provided inside the housing, that is, the tool gripping section 4 . The reversible electric motor M can be connected to an external power supply (not shown) through a power cord 5 . The electric motor M can be driven and stopped by the on-off switch 6 provided on the tool grip part 4, or the rotation direct...

Embodiment 2

[0094] In the above-mentioned embodiment, the case where the present invention is applied to an electric tailless helical coil insert insertion tool has been described, but the present invention can also be applied to a manual tailless helical coil insert insertion tool as well.

[0095] Figure 9 In the following, an embodiment of the manual tailless helical coil insert insertion tool 1 of the present invention will be described. The manual tailless helical coil insertion tool 1 of the present embodiment is the same as that described in Embodiment 1. Figure 6 The structure in which the mandrel assembly 40 is assembled on the precoiler 30 shown in FIG. However, the cylindrical frame of the precoiler 30 is made into a slightly elongated shape in the axial direction in order to be suitable for holding, and a drive handle is provided on the mandrel 43 instead of the drive hub 41 driven by the drive motor M. 41A is configured to manually rotate and drive the mandrel 43 . When ...

Abstract

Provided is a tangless helical coil insert inserting tool which has a simpler structure as compared with a conventional tool, which is also simply manufactured and assembled, accordingly the manufacturing cost of which can be reduced, and in addition which is excellent in operability. The tangless helical coil insert inserting tool (1) comprises: a mandrel (43), at least the end portion of which forms a threaded axis (45) in order to insert a tangless helical coil insert (100) into a workpiece; and a pivot nail (80) provided with a nail portion (81) engaged with a notch (101) of an end coil portion of the tangless helical coil insert (100) screwed to the threaded axis (45). The pivot nail (80) has an elastic linking member (83) having one end fixed to a pivot nail attaching groove (71) and the other end attached to the nail portion (81). The elastic linking member (83) presses the nail portion (81) in the outward radial direction of the threaded axis (45) so that a hook portion (90) formed on the nail portion (81) is engaged with the notch (101) of the tangless helical coil insert (100) in a spring back fashion.

Description

technical field [0001] The present invention relates to a tailless helical coil insertion tool for fitting a tailless helical coil insert into a tap hole of a workpiece. Background technique [0002] In the past, in the state of directly tapping the workpiece made of light metal such as aluminum, plastic, cast iron, etc., when the female thread was weak and high fastening force could not be obtained, the screw connection with high reliability was used. Compensating helical coil inserts. [0003] Helical coil inserts include tailed helical coil inserts and tailless helical coil inserts. However, helical coil inserts with tails need to be assembled to the workpiece to remove the tail, and then remove the removed tail. Recycled jobs. Therefore, there are cases where tailless helical coil inserts that do not require such work are used. [0004] Patent Document 1 discloses an installation tool for this tailless helical coil insert. Refer to the attached Figure 10 ~ Figure 12...
