Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to the replacement work of automobile clutch plates, and more specifically relates to a jig for easily aligning and holding the center of the clutch plate with the center of the pressure plate. It is.

<Prior Art and its Problems> A clutch is a connecting mechanism for engine power, and is used to temporarily prevent engine torque from being transmitted to the transmission when changing gears, starting, or stopping the vehicle. In other words, the main shaft on the transmission side is connected to the shaft hole of the clutch plate, which is in planar contact with and separated from the flywheel on the engine side, and power is transmitted, but the clutch plate wears out each time it comes into pressure contact with the flywheel. Due to damage, only the clutch plate needs to be replaced.

Therefore, in the replacement work, the transmission is first removed, the pressure plate that connects and separates the clutch plate from the flywheel is removed from the flywheel, and the clutch plate is replaced.When installing a new clutch plate, It is necessary to attach the pressure plate to the flywheel while aligning the center axis of the flywheel with the center axis of the clutch plate and pressing it against the flywheel surface. At the tip of the body a, a removable clutch shaft hole insertion member b is fitted to match the shaft hole diameter of the clutch plate, and a removable pilot bearing fitting is fitted to match the pilot bearing diameter provided in the center shaft hole of the flywheel. Using a tool d (commonly called a Mendra chain gear) consisting of a member c and a tool d, pass through the shaft hole of the clutch plate and hold the clutch plate fitted in the pilot bearing while frying the pressure plate. It is attached to the wheel. However, with this method, since the shaft hole diameter and pilot bearing diameter differ depending on the vehicle model, each time a clutch shaft hole insertion member b and a pilot bearing fitting member c are attached to the rod a according to the respective diameters. It is very time consuming to select and install the parts, and there are problems such as very low work efficiency. Furthermore, with the diversification of vehicle models in recent years, these problems are increasingly leading to a decline in work efficiency.

In order to solve the above-mentioned problems, the present invention provides a clutch plate mounting jig that can align the centers of the clutch plate and the pressure plate and press them together, regardless of the size of the shaft hole diameter of the clutch plate. The purpose is to

<Means for solving the problems> The above object of the present invention can be achieved by a jig having the following configuration. That is, the gist is that a screw rod insertion hole is provided through the upper center of the jig body which is bent into a gate shape, and an operating screw rod with a handle attached to the base end is inserted into the screw rod insertion hole. At the same time, a vertical sliding member whose both ends are loosely fitted to a rail member protruding from above and below both inner surfaces of the jig main body is screwed through the rail member on the distal end side thereof in a loose manner. Further, on both sides of the vertical sliding member, clutch holding members having clutch plate shaft hole locking pieces projecting outwardly at their tips are arranged symmetrically so that their inner sides abut each other from the middle, and furthermore, their tips are The proximal ends of the jig body are pivoted so as to be located on the center line of the jig body, and a long hole is provided in the proximal end side of the clutch holding member, and a sliding pin is inserted into the long hole in a loose manner. and its both ends are supported by a clutch holding leg opening member pivotally connected to the tip of the operating screw rod, and a pressure plate pressing annular member is attached to the tip of the jig main body, and the above operation is carried out. This clutch plate mounting jig is characterized in that a vertical adjustment female screw member is screwed through the screw rod.

<Embodiments and Effects> The clutch plate mounting jig according to the present invention will be described in detail below with reference to drawings showing embodiments thereof.

Fig. 1 is a perspective view of the present invention, and Fig. 2 is a front view of the same. 1 is a jig body made by bending a steel member into a shape, and a screw rod insertion hole 2 is provided in the upper center of the jig body 1. is opened, and an operating screw rod 4 having a handle portion 3 attached to the proximal end thereof can be freely inserted into the screw rod insertion hole 2 in a loose manner. Next, rail members 5, 5 are placed over the top and bottom of both inner side surfaces of the jig main body 1.
Form a protrusion. Therefore, a vertical sliding member 6 is provided in the center of which the rail members 5, 5 are fitted at both ends and through which the operating screw rod 4 is threaded. By moving the screw rod 4 up and down, it slides on the rail members 5, 5 and moves up and down, and the operation screw rod 4 screws through the vertical adjustment female screw member 7. By doing so, the vertical sliding member 6 can be vertically adjusted. Clutch holding members 10, 10, whose proximal ends are pivotally supported by pivot pins 8, 8 on both sides of the vertical sliding member 6, and whose distal ends are formed with clutch plate shaft hole locking pieces 9, are placed in a symmetrical shape. The clutch holding members 10, 10
are in a state in which their inner surfaces abut against each other from the middle, and the clutch plate shaft hole locking piece 9 at the tip protrudes from the center of the ring-shaped pressure plate pressing annular member 11 attached to the tip of the jig main body 1. It is something that is formed. Furthermore, the clutch holding member 10,1
Elongated holes 12, 12 are formed through the base side of 0, extending above and below, and the elongated hole 1 is provided at the tip of the operating screw rod 4.
A sliding pin member 1 that is loosely inserted into 2 and 12
3, 13 supporting both ends of the clutch holding member 1
Clutch holding leg opening member 14 for passing 0,10
It is a pivot point. That is, as shown in Figure 3,
By rotating the operating screw rod 4, the clutch holding leg opening member 1 is screwed into the vertical sliding member 6.
4 and the vertical sliding member 6, the clutch holding members 10, 10 can be adjusted in a spread-like manner.

In the present invention having the above configuration, as shown in FIG. 4, the clutch plate B is placed on the pressure plate A surface.
The above pressure plate A center and clutch B
With the inner surfaces of the clutch holding members 10, 10 of the mounting jig c of the present invention in contact with each other so that the centers are substantially flush with each other, rotate the vertical adjustment female screw member 7 to remove the clutch holding member. 10, 10 are moved forward to penetrate the clutch plate shaft hole locking pieces 9, 9 at the tip from inside the shaft hole D of the clutch plate B.

Then, as shown in FIG. 5, by rotating the handle portion 3 and rotating the operating screw rod 4 to open the clutch holding members 10, 10, the clutch plate shaft hole locking piece 9 at the tip thereof is opened. , 9 are firmly engaged with the peripheral edge of the shaft hole D. Further, from this state, by rotating the vertical adjustment female screw member 7 in the opposite direction and moving the operating screw rod 4 toward the front, the pressure plate A and the clutch plate B are adjusted to the position in the clutch plate shaft hole. The retaining pieces 9, 9 and the pressure plate pressing annular member 11 firmly press and hold the plate in a centered position. Then, as shown in Figure 6, on the flywheel E of the engine,
Align the periphery of the pressure plate A above,
By connecting with screws F, F, . . . , the center of the shaft hole D of the clutch plate B and the center of the flywheel E are automatically aligned.

<Effects of the invention> As described above, according to the invention, the pressure plate and the By passing the clutch retaining member through the center of the clutch plate and making the tips split open, they can be pressed together and held together, making it extremely easy to attach the clutch plate to the flywheel. With the recent emergence of front-wheel drive vehicles and the recent emergence of front-wheel drive vehicles, the number of vehicle models with different shaft hole diameters is increasing year by year.
