Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a terminal crimping device for crimping and attaching a terminal to the end of a wire to be held.

Generally, this type of terminal crimping device 1 has a structure in which an upper die is attached to the lower end of a ram that moves up and down, and a lower die is attached to a portion of the frame that faces the upper die. When a terminal is crimped onto a covered wire using such a terminal crimping device (in this case, the covered wire and terminal material are set on the lower die, the ram is moved downward, and the upper die and the lower die are used to crimp the terminal). The terminal is attached to the wire by tightening it.

By the way, in such a terminal crimping device, when the coated wire or the terminal material is changed, it is necessary to replace the upper mold and the lower mold according to the warp. However, the dimensions or mounting methods for conventional upper and lower types differ depending on each terminal crimping device manufacturer.For this reason, if the manufacturer of the terminal crimping device and the manufacturer of the upper and lower types are different, This type of terminal crimping device can be attached to a terminal crimping device. Therefore, it is necessary to prepare various terminal crimping devices according to the type of coated wire or terminal material, and there is a problem that the cost of the device becomes enormous.

This invention was made to solve the above problem.
It is an object of the present invention to provide a terminal crimping device to which various upper and lower molds can be attached.

The advantage of this invention is that the upper and lower molds are each attached to the movable body and the frame via holders, and the holders are changed when the upper and lower molds are changed.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 10 attached hereto. In addition, Figure 1 is a front view showing this invention (this device is partially cut away), Figure 2 is a sectional view taken along the line G in Figure 1, and Figure 3 is a sectional view taken from the left. FIG. 4 is a partially omitted view taken along arrow 1v in FIG. 2.

In the figure, reference numeral 1 is a base. A thin mounting plate 3 is fixed to the base 1 via a support member 2. In this installation, a frame 4 is fixed to the upper surface of the plate 3. A rotary shaft 7 is rotatably mounted horizontally on the upper part of the frame 4 via bearings 5 and 6.
A pulley 10 is rotatably provided at the rear end of the vehicle via bearings 8 and 9. This pulley 10 is attached to a belt 11.
It is rotated by a motor 13G via a bifurcated pulley 12 for both 50 Hz and 60 Hz. The rotation of the pulley 10 is transmitted to the rotating shaft 7 by a well-known clutch 14. That is, when the foot switch (not shown) is turned on, the lenoid 15 acts,
The engagement between the stopper 16 and the protrusion 14a of the clutch 14 is released, and the clutch 14p is rotated. Rotation of the clutch 14 is transmitted to the rotating shaft 7 via the key 17. Note that when the boo IJ 10 rotates once, the stopper 16 is returned to its original state by the spring 18, and the stopper 16 and the protrusion 14a are engaged and the clutch 14 is stopped (this causes the rotating shaft 7 to stop). It has become.

On the other hand, a protrusion 7a eccentric from the axis of the rotary drill 7 is formed on the tip surface of the rotating shaft 7, and this protrusion 7a allows the ram (moving body) 19 to reciprocate in the vertical direction. ing. In other words, the tip of the frame 4)
A ram 19 is provided so as to be able to reciprocate vertically. A recess 19a extending horizontally is formed in the center of the back surface of the ram 19. A protrusion 7a is inserted into the recess 19a, and a sleeve 20 is rotatably molded around the outer periphery of the sleeve 7a. Moreover, sleeve 2
0 can freely slide into the recess 19a. Therefore, when the rotating shaft 7 rotates, the protrusion 7a smoothly moves relative to the recess 191 in the direction in which it extends, and the ram 19 reciprocates in the vertical direction. The projection 7a, the recess 19a, and the sleeve 20 constitute a rotation-to-reciprocating motion conversion mechanism. A protrusion 21a is formed at the center of the end face (this is the first center part of the stone) extending in the front and back directions.Furthermore, on the front surface of the ram 19, there is a mounting plate extending in the upper direction in FIG. Groove 19b is formed.This installation is performed using groove 1.
9b (Moss, upper die holder 22 is inserted, and this holder 22 is fixed to the ram 19 via a plate 24 by bolts 231 screwed into the front surface of the ram 19.

A bolt 25 is fixed to the lower end surface 1 of the holder 22 with the body and head projecting upward from the holder 22. The barrel of the bolt 25 (this is where the adjustment ring 26 and spacer ring 27 are attached) has eight protrusions 26a formed at equal intervals in the circumferential direction on the upper end surface of the adjustment ring 26. These protrusions 26a are
The heights of two pairs located on a line passing through the center of the sub-cylindrical ring 26 are the same, and the heights of the other pairs are slightly different from each other. Therefore, the protrusion 26H
By bringing any one of them into contact with the protruding portion 21a of the top plate 21, the position of the holder 22 against which the ram 19 is pressed can be adjusted as appropriate in the vertical direction.

Holder 22 attached to ram 19 in this way
As described below, the core wire upper mold 28 and the coating upper mold 29 are attached so as to be able to adjust their positions in the vertical direction. That is, as shown in Figure 5,
The upper front side of the holder 22 (this is the small diameter part 30a on the front side)
A hole 30 consisting of a large diameter portion 30b on the back side and a large diameter portion 30b is formed. An adjustment dial 31 is inserted into the small diameter portion 30a. The body portion 31a of the adjustment dial 31 has a beveled cross section. The distances from each side of this angle shape to the axis of the adjustment dial 31 are slightly different from each other, and the distances from each side to the axis of the adjustment dial 31 are slightly different from each other.
Numbers 1 to 8 are attached to the front end surface of 1. On the other hand, hole 3
A stopper 32 having a larger diameter than the small diameter portion 30a is inserted into the large diameter portion 30b. This stopper 32 is the bolt 3
3, the adjustment dial 31 is fixed, thereby preventing the adjustment dial 31 from being removed.

In addition, the front surface of the holder 22 has holes 30 (a series of holes) at the upper end.
+'fd A recess 22a whose lower end extends to the lower end of the holder 22 is formed. A first intermediate plate 34 is disposed at the upper end of the bottom surface of the recess 22a, the upper end of which touches the downwardly facing side of the body 31a of the adjustment dial 31. A through hole 34a is formed in the center of the first intermediate plate 34, and the through hole 34a is formed in the four parts 22a of the holder 22.
The small diameter portion 36a of the sleeve 36 is fixed to the bottom surface of the sleeve 36 by a bolt 35. sleeve 36
The diameter of the small diameter portion 36a is larger than the diameter of the through hole 34a.
It is smaller than at least the difference in distance from the axis between the side marked with the number 8 and the side marked with the number 1 of the body 31a of the adjustment dial 31. Furthermore, the length of the small diameter portion 36a is slightly longer than the thickness of the first intermediate plate 34.

Therefore, while the C1 sleeve 36 remains fixed to the holder 22 by the bolts 35i, the first intermediate plate 34 can be moved in the vertical direction with respect to the holder 22 using the adjustment dial 31. The outer periphery of the large diameter portion 36b of the sleeve 36 has a tapered shape with a smaller diameter on the small diameter portion 36a side, and the second intermediate plate 37
are fitted. The upper end of the second intermediate plate 37 is in contact with the cross section of the AA section dial 31 having a circular cross section.

Therefore, the second intermediate plate 37 is shaped so that it cannot move in the vertical direction.

Further, at the lower end of the recess 22a of the holder 22, from the bottom side toward the open side, there is a +10th order between the core wire of the coated wire (not shown) and the terminal material (indicated by reference numeral 73 in FIG. 10). an upper die for core wire 28 for crimping, and an upper die for covering 29 for crimping between the covering portion of the covered wire and the terminal material 73;
and press fii38 is placed 4. The upper die 28 for core wire and the upper die 29 for coating have their respective upper end surfaces connected to the first intermediate plate 34.
It is in contact with the lower end of the
