Description

Scrap iron removing device for machining in guide hole of brake caliper support

Technical Field

The utility model belongs to the technical field of automobile part machining assistance, and particularly relates to a scrap iron removing device suitable for machining in guide holes of brake caliper supports of various series.

Background

In an automobile brake system, a brake caliper is used as an actuating element of a brake terminal, and generally, a piston is pushed by hydraulic pressure or air pressure, and then the piston pushes a friction plate to press a brake disc, so that the braking purpose is realized by virtue of friction force. As a single-side piston structure, the floating brake caliper is widely applied due to the advantages of simple structure, low cost, convenience in maintenance and the like.

The floating brake caliper is composed of a fixed caliper frame and a floating caliper body, the caliper frame is fixed on a steering knuckle through a bolt, the caliper body is connected with a guide pin into a whole through a caliper body fastening bolt, and is inserted into a guide hole in the caliper frame through the guide pin and moves in the direction of a hole core in the guide hole, and the caliper body and the guide pin synchronously slide. When the automobile brakes, the piston pushes the friction plate on one side to move, when the friction plate contacts the brake disc, the caliper body moves towards the direction far away from the disc surface of the brake disc, and the friction plate on the opposite side of the piston on the caliper body moves towards the side where the disc surface of the brake disc is located until the friction plates on the two sides of the brake disc are abutted against the disc surfaces on the two sides of the brake disc, so that the purpose of braking is achieved.

At present, a guide hole on an automobile brake caliper body is in clearance fit with a guide pin, and lubricating grease is also injected into the guide hole to reduce friction force in order to ensure that the guide pin slides freely. The guide pin hole on the existing brake caliper body is also of a blind hole structure, so that chips are difficult to remove after processing, and if the guide pin hole is not cleaned up in time, the inner wall of the guide pin hole is easily scratched, so that the performance of products is influenced, and no special equipment is available for cleaning chips in the guide hole at present.

Detailed Description

As shown in the figure, the lower section of a vertically arranged air pipe 20 is fixed on a support 10, the lower end of the air pipe 20 is communicated to an air source, and an air outlet hole is formed in the air pipe 20. The scheme is that the air flow is utilized to disturb the debris attached to the inner wall of the guide hole, so that the cleaning of the hole cavity of the guide hole is ensured. Because the air pipe 20 is vertically arranged, the orifice of the guide hole can only face downwards during chip removal cleaning, and therefore chip removal cleaning airflow is discharged downwards, so that chips cannot be scattered accidentally, and the collection of the chips is facilitated.

Preferably, the air tubes 20 are arranged in two parallel spaced-apart relationship with a spacing therebetween corresponding to the spacing between the guide holes. Therefore, the two guide holes in the same brake caliper support can simultaneously complete cleaning operation, and the operation efficiency is improved.

The lower parts of the two air pipes 20 are respectively provided with a connecting block 21, the connecting blocks 21 are connected on the cross bar 11, and the two connecting blocks 21 are connected in a distance-adjustable manner. The scheme is to realize the adjustment of the distance between the air pipes 20, and the universality of the equipment is improved due to the fact that the distances between the guide holes of the brake calipers with different specifications possibly differ.

As a preferred example of the adjustment scheme, namely, a sliding groove 111 is formed on the cross bar 11, at least one of the two connecting blocks 22 is matched with the sliding groove 111, and a positioning pin 30 is arranged between the two connecting blocks for positioning. The groove wall of the sliding groove 111 and the side surface of the connecting block 22 are provided with hole sites 112, corresponding hole sites are selected to be aligned and are pinned by the locating pin 30, and the position adjustment and the limiting are both convenient and reliable.

The support 10 comprises a bottom transverse frame 12, a side vertical frame 13 is arranged on one side of the bottom transverse frame 12, a vertically arranged limit groove 131 is arranged on the side vertical frame 13, a cross rod 11 for connecting the air pipe 20 is horizontally arranged above the bottom transverse frame 12 in parallel, one end of the cross rod 11 and the limit groove 131 on the side vertical frame 13 form vertical displacement matching, the cross rod 11 is connected with the lifting mechanism 40, and the latter drives the cross rod 11 to move vertically. The scheme reasonably utilizes the space below the cross rod 11 to arrange other parts, and improves the space utilization rate.

And a gas distribution valve 50 is arranged at the joint of the bottom cross frame 12 and the side vertical frame 13 which are positioned below the cross rod 11, and a branch pipe 51 of the gas distribution valve 50 is connected with the gas pipe 20. An on-off valve may also be provided upstream of the gas distribution valve 50 to control specific timing of operations.

The top end of the air pipe 20 is provided with an air hole 22, the side wall is provided with a side air hole 23, the hole core of the side air hole 23 is obliquely arranged from inside to outside and from top to bottom, and the cushion-shaped protective layer 70 is arranged on the connecting block 21. The plurality of side air holes 23 are arranged on the circumferential surface of the pipe wall, and generally, the symmetrical arrangement is selected, and the air holes 22 and the side air holes 23 can effectively and efficiently remove cutting chips. The protective layer 70 can prevent the upper end surface of the connecting block 21 from being washed when the debris is discharged, and the protective layer 70 can be replaced after being damaged.

In addition, a scrap collecting box 60 is arranged on the bottom cross frame 12, and rollers 121 are arranged at the bottom of the bottom cross frame 12. This facilitates debris collection and facilitates easy movement of the utility model into position.
