Description

[Detailed description of the invention] (Field of industrial application) This invention is used for positioning the VL joint when installing a propeller shaft in which a Revlo type joint (hereinafter referred to as VL joint) is used. Regarding improvements to jigs that can be used.

(Prior Art) Conventionally, as a jig for attaching a propeller shaft, there is a technique disclosed in Japanese Utility Model Application No. 57-47582 by the present applicant.

In addition, when installing a propeller shaft that uses a ball joint such as a VL joint on a vehicle, a jig is required to position the VL joint attached to the propeller shaft and to prevent damage to the boot due to excessive bending of the VL joint. An example of this jig is shown in Figures 6 and 7.
As shown in the figure. In addition, Figure 5 shows the propeller shaft 1.
This shows that VL joint 2 is installed, and VL joint 2 has
A boot 3 is provided to seal the inside.

The jig 4 shown in FIGS. 6 and 7 is fixed to the VL joint 2 portion (range A in FIG. 5) of the propeller shaft 1, and has an interior formed so that the VL joint 2 can be stored therein. , which has an opening 5 opened at an angle of approximately 180 degrees on the side surface.

The jig 4 is attached to the VL joint 2 of the propeller shaft 1 by tightening the bolt 7 provided on the bracket 6 attached to the outer periphery of the jig 4. This is done by holding the joint part between 8 and jig 4.

In this way, the jig 4 is fixed to the VL joint 2 of the propeller shaft 1, and the jig 4 is used to adjust the VL when installing the propeller shaft 1 to a vehicle.
Positioning such as centering of joint 2,
The bending angle of the VL joint 2 is regulated to ensure reliable attachment to the vehicle and to prevent damage to the boot 3 of the VL joint 2.

(Problems to be solved by the invention) However, in the conventional jig 4, the bolts 7 are tightened and loosened to attach and detach from the VL joint 2, which makes the work complicated and requires a lot of work. There was a problem in that it was time-consuming and hindered the improvement of productivity in vehicle assembly line production.

The present invention was devised in view of the above problems, and an object of the present invention is to enable a jig to be easily attached to or detached from a joint portion of a propeller shaft.

(Means for Solving the Problems) In order to solve the above-mentioned problems and achieve the purpose, the present invention provides a structure in which the ball joint of the propeller shaft is attached at least 180 degrees to the side of the fixed attachment that can accommodate the ball joint part of the propeller shaft. An opening opening at an angle of 180 degrees is formed, and further, from the end of the opening, it slides into contact with the outer periphery of the accommodated ball joint part and moves forward and backward in the circumferential direction to open the opening at an angle smaller than 180 degrees. It is equipped with a movable attachment that narrows the area.

(Function) The ball joint part of the propeller shaft is housed in the fixed attachment from the opening. At this time, the movable attachment is kept in a standby position where it does not block the opening, and once the ball joint is retracted, the movable attachment is brought into sliding contact with the ball joint and moved in the circumferential direction to close the opening. Block it,
Attached to the ball joint.

In this way, the jig can be reliably fixed to the ball joint, and the jig can be attached and detached by the simple operation of moving the movable attachment.

(Example) Next, an example of the present invention will be described based on FIGS. 1 to 4.

The fixed attachment 9 is shaped so that the VL joint 2 of the propeller shaft 1 can be accommodated inside, and has an opening 1 opened at 180 degrees on the side.
0 is formed. The fixed attachment 9 is provided with two movable attachments, a first movable attachment 11 and a second movable attachment 12.

The first movable attachment 11 is for fixing the outer race portion of the VL joint 2 and is formed along the outer periphery of the fixed attachment 9. It is slidably attached to the T-slot 13. This first movable attachment 1
To explain the configuration of 1 in detail, VL joint 2
a sliding part 14 having the same curvature as the outer periphery of the outer race part 2a in order to come into sliding contact with the outer race part 2a; a sliding part 15 fixed to the sliding part 14 and sliding within the T-groove 13; a handle attachment part 17 fixed to the sliding part 15 and to which one end of the handle 16 is attached;
It consists of.

A stopper 18 is attached to the upper end of the T-slot 13, and the sliding portion 15 comes into contact with the stopper 18 to restrict the amount of protrusion of the sliding portion 14 of the first movable attachment 11. In this embodiment, the sliding contact portion 14 has a diameter of 60 mm.
It is regulated so that it protrudes to a degree angle.

Continuing, the second movable attachment 12 is
This fixes the shaft portion 2b of the VL joint 2, and this also includes a sliding contact portion 19 having the same curvature as the outer periphery of the shaft portion 2b, and a T-slot 20 formed along the outer periphery of the fixed attachment 9. The other end of the handle 16 is fixed to the upper surface of the sliding part 21.

A stopper 22 is also provided at the upper end of the T-slot 20 to limit the amount of protrusion of the sliding portion 19 of the second movable attachment 12 to an angle of 60 degrees.

A pin 23 is provided at the end of the opening 10 of the fixed attachment 9, and a coil spring 24 is installed between the pin 23 and the handle 16. Then, due to the tensile force of the coil spring 24, the first movable attachment 11 and the second movable attachment 12 are moved in the protruding direction (opening 10) via the handle 16.
(in the direction of blocking the area).

Note that 25 in the figure is a handle provided on the fixed attachment 9.

Next, the operation related to the above configuration will be explained.

First, attach the jig with the above configuration to the propeller shaft 1.
When attaching to the VL joint 2, hold the handle 16 and the handle 25 and move the handle 16 in the direction of the handle 25 against the biasing force of the coil spring 24. The sliding portion 19 of the movable attachment 12 retreats from the opening 10. Then, the VL joint 2 is housed in the fixed attachment 9 through the opening 10 opened at an angle of 180 degrees. Once retracted, simply releasing the handle 16 causes the sliding contact portion 14 of the first movable attachment 11 and the sliding contact portion 1 of the second movable attachment 12 to move due to the tensile force of the coil spring 24.
9 protrude up to an angle of 60 degrees while slidingly contacting the outer peripheries of the outer race portion 2a and shaft portion 2b of the VL joint 2, respectively. In this way, the jig can be easily attached to the VL joint 2.

Then, with the jig attached in this way, the propeller shaft 1 is assembled into the vehicle,
The position of VL joint 2 and the bending angle of VL joint can be controlled.
Secure assembly and VL joint 2 boots 3
This can prevent damage to the product.

When the propeller shaft 1 has been assembled to the vehicle, the jig is removed from the VL joint 2.
This removal can be done by performing the reverse operation of the above-mentioned installation.

As described above, the jig of this embodiment can be attached to and detached from the VL joint with a single touch.

(Effects of the invention) As explained in detail above, the present invention provides a movable attachment that slides on the outer periphery of the ball joint and can move forward and backward in the circumferential direction, in the opening of the fixed attachment in which the ball joint can be stored. Since the jig can be attached and detached from the ball joint by moving the movable attachment, the jig attachment work is simplified and the work time can be shortened.
