In such a case, the caliper 8 is moved toward the work W in the state of the sliding faces to the brake disc 3 of a pair of brake pads 9, 9' fitted in advance into this caliper 8 becoming horizontal and the brake disc 3 is inserted into the gap between the pads 9, 9'.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a brake caliper mounting method when assembling a disc brake device for a vehicle.

(Prior art) A disc brake device for a vehicle includes a disc-shaped brake disc, and a pair of left and right pads that support a pressurizing cylinder across the brake disc, and slide on both sides of the brake disc by the action of the cylinder. The brake caliper is equipped with a tank bottom.

This disc brake device has good heat dissipation, prevents fade phenomenon, and has stable braking performance at high speeds.
Also, even if water or mud adheres to the brake disc,
It is widely used because it has many advantages such as quick recovery of braking force because it is dispersed by centrifugal force.

However, because the clearance between the brake disc and the pad is extremely small, when assembling a brake caliper to a workpiece that includes a brake disc when assembling a disc brake device, the brake disc must be inserted into the gap between the pads. The work was difficult.

(Objective of the Invention) Therefore, an object of the present invention is to provide a brake caliper mounting method that allows a brake disc to be easily and smoothly inserted into the gap between a pair of pads.

(Structure of the Invention) The brake caliper mounting method according to the present invention is such that the brake caliper is set in advance so that the mounting end of the pair of butts is expanded wider than the opposite end, and then the brake caliper is inserted into the gap between the pair of pads. It is characterized by inserting a brake disc.

(Effects of the Invention) According to the present invention, when a brake caliper is installed, the installed end side of the gap between the pair of pads included in the brake caliper is enlarged beyond the preset gap dimension. This has the advantage that it is extremely easy to insert the brake disc into the gap.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIG. 1 is an overall plan view of a brake caliper mounting device applied to the implementation of the present invention, and FIG. 2 is an overall side view with a part cut away and a cross section. The overall outline will be explained based on FIGS. 1 and 2.

↓ is a jig pallet conveyed by the pallet conveyor 2, and a workpiece W is mounted and fixed on this jig pallet 1. In this case, the work W is a steering knuckle assembly for a front wheel of an automobile, and a brake disc 3 of a disc brake device is rotatably attached thereto. The workpiece W is placed in a state where the rotational axis 4 of the brake disc 3 is oriented vertically, that is, with the pad sliding surface of the brake disc 3 horizontal.
It is mounted on a jig pallet 1.

A working robot 6 equipped with an arm 6a is arranged near the pallet conveyor 2. This working robot 6 has a brake caliper 8 supplied from a supply conveyor 7 on a robot hand 5 attached to the tip of an arm 6a.
The caliper 8 is then clamped by the caliper 8, and then carried toward the workpiece W through a predetermined path and mounted on the workpiece W. In that case, the caliber 8 moves toward the workpiece W in a state where the sliding surfaces of the pair of brake butts 9 and 9' installed in advance in the caliber 8 and the brake disc 3 are horizontal, and The brake disc 3 is inserted into the gap between 9 and 9'.

FIG. 3 shows a top view of the brake caliper 8 with a pair of brake pads 9,9' therein, and FIG. 4 shows a rear view thereof. Brake caliper 9.9' is shown in Figure 5~
As shown in FIG. 7, the bat main body 9a has a structure in which it is adhered onto a bat substrate 9b having a slightly larger area.

A pair of springs 20, 20 are mounted between the back surfaces of the pad substrates 9b, 9b of the bat 9.9'.
′ is biased in the direction of opening. Pl and P2 are springs 20 and 20 on the pad substrate 9b of the lower pad 9'.
It is the anchoring point of

Recesses 10 are formed on both sides of the butt board 9b, and the recesses 10 and 10 are formed on the left and right inner walls of the brake caliper 8 at the positions shown in FIGS. 3 and 4, respectively. Guide 1 extending vertically
1.11, respectively, so that the pad 9.9' slides while being guided by these pair of guides 11.11. In this case, as shown in FIG. 8(a), a slight gap 21 is formed between the recess 10 of the pad substrate 9b of the lower pad 9' and the guide 11. Due to the presence of pad 9'
When an upward force F acts on a point P3 at the center rear end of the bottom surface of the pad base plate 9b, the pad 9' tilts about the point P4 at the front end of the bottom wall 8a of the brake caliper 8 as a fulcrum, and the pad 9' The front end side (mounted end side) of the pads 9 and 9' is expanded so that the brake disc 3 can be smoothly inserted into the gap between the pads 9 and 9'. Note that the point of action P3 of the force F on the bottom surface of the pad 9' is, as shown in FIGS. 5 and 6, on the pad substrate 9b of the pad 9'.
It is necessary that the springs 20 and 20 are located outside the straight line connecting the engagement points P1 and P2 of the springs 20 and 20, respectively.

FIG. 9 shows an example of the configuration of the robot hunt 5 that the working robot 6 is equipped with. The robot hand 5 includes a slide base 13 that includes two upper clamp arms 12U, 12U for clamping the caliper 8 from above and below, and one clamp arm 12L at the center of the lower side, which is slidable in the vertical direction. It is equipped with A clamp cylinder 14 is attached to the slide base 13 to operate the clamp arms 12U and 12L in synchronization with each other so that the clamping direction and the unclamping direction match, and when the clamp cylinder 14 is operated, , clamp arm 1
2U and 12L are configured to slide vertically via a synchronization mechanism (not shown) to clamp or unclamp the body of the caliper 8. Further, in order to absorb vertical positional deviation of the clamp arm 12U112L, the slide base 13 is attached to a base member 15 fixed to the tip of the robot arm 6a so as to be slidable in the vertical direction, thereby forming a floating mechanism. . The slide base 13 is connected to a piston of a balance cylinder 16 fixed to the base member 15.

An upward force F is applied to the tip of the clamp arm 12L for clamping the central part of the lower surface of the caliper 8 to a point of application P3 on the lower surface of the pad base plate 9b of the lower pad 9' to tilt the pad 9'. A mechanism is installed to make this happen. This mechanism includes a bushing rod 22 provided at the tip of the clamp arm 12L so as to be slidable in the vertical direction;
It consists of a drive motor 23. When the motor 23 is activated, the bushing rod 22 is moved to the bottom wall 8 of the caliper 8.
The pad 9' is configured to be tilted by protruding into the inside of the caliper 8 from the opening formed in the pad 9' and applying a force F to the point of action P3 of the pad substrate 9b of the pad 9'.

The above explanation has clarified the structure and operation of an example of the device to which the brake caliper mounting method according to the present invention is applied. According to this embodiment, when the brake caliper is mounted by the robot hand 5, the pad 9. Since the mounting end side of the gap 9' is made larger than the preset gap 1, insertion of the brake disc 3 into the gap becomes extremely easy.
