Abstract

The utility model belongs to a clamp, and relates to a clamp for a brake disc fastener in particular. The appearance of the clamp for the brake disc fastener relates to a column platform which is smaller in the upper and bigger in the lower; the clamp for the brake disc fastener has the key points that the clamp is a hollow sleeve; the inner holes of the clamp are divided into three parts from up to down, wherein a lower hole is a big round hole; the inner diameter of the lower hole is slightly larger than the diameter of the inner hole of a brake disc; and the outer diameter of the lower hole is smaller than the diameter of a processing hole required by the brake disc; the shape of a middle hole is same with that of a cylinder squeeze head; the diameter of the middle hole is larger than the outer diameter of the cylinder squeeze head, and is smaller than the protruding outer diameter of the cylinder squeeze head; two ends of the middle hole are provided with grooves so that the cylinder squeeze head can penetrate through; the diameter of an upper hole is slightly larger than the protruding diameter of the cylinder squeeze head and the depth of the upper hole is the same with the thickness of the cylinder squeeze head; two locating pins are additionally mounted on the upper part of the inner hole; the distance between the center line of one locating pin and the symmetric line of the grooves is the sum of a half of the width of the groove and the radius of the locating pin; and the other locating pin is arranged between the two locating pins, and has the arc interval with the first locating pin exceeding the sum of the widths of the two grooves and the diameter of the locating pin. The clamp for the brake disc fastener is convenient and quick to operate, and the working intensity is reduced.

Description

The anchor clamps of brake disc securing member

Technical field

The utility model belongs to the anchor clamps in the workpiece processing, especially belongs to the anchor clamps of brake disc securing member.

Background technology

The processing technology in hole as shown in Figure 1 on the present Ling Shuai automobile brake disc, be that brake disc is placed on the oil cylinder 6 of machine table 5, anchor clamps 1 are placed between brake disc 7 and the oil cylinder pressure head 4, start oil cylinder 6, oil cylinder pressure head 4 is pressed on brake disc 7 on the machine table 5 by anchor clamps 1, the shape of oil cylinder pressure head 4 as shown in Figure 2, the upper end is to have two relative circular arcs to protrude 8 on the cylindrical circumference, the lower end is the less cylinder of diameter, so the anchor clamps 1 that borehole engineering is commonly used as shown in Figure 3 usually, be a up-small and down-big cylinder table, opening 2 arranged on the circumference, because of the brake disc internal diameter too small, the anchor clamps 1 that borehole engineering is commonly used can not be put into, can't clamping process,, will make anchor clamps 1 can't be clamped to brake disc again because of lower outer diameter is too small if reduce the lower cylindrical diameter of anchor clamps 1.And oil cylinder pressure head 4 is exposed to anchor clamps 1 outside, and operating personnel might be by oil cylinder pressure head 4 tongs in the process of clamping tool 1 and be injured.

Summary of the invention

The utility model purpose is to overcome the shortcoming that existing anchor clamps exist, and provides a kind of quick and easy for installation, can reduce the anchor clamps of the brake disc securing member of labor intensity of operating staff and danger.

The technical scheme that the utility model adopted is a kind of anchor clamps of brake disc securing member, profile is up-small and down-big cylinder table, its structural feature is, anchor clamps are the sleeve of hollow, its endoporus is divided into three parts from the bottom to top, following Kong Weiyi big hole internal diameter is more bigger than the internal orifice dimension of brake disc, external diameter is less than the required machining hole of brake disc place, the shape of mesopore is identical with the oil cylinder pressure head, the aperture greater than with the external diameter of oil cylinder pressure head, the external diameter that protrudes less than the circular arc of oil cylinder pressure head, the fluted oil cylinder pressure head that makes in two ends passes, it is identical that last bore dia is slightly larger than the diameter that the circular arc of oil cylinder pressure head protrudes, the degree of depth is identical with the thickness of oil cylinder pressure head, adds two alignment pins on the top of endoporus, and the distance of the line of symmetry of alignment pin center line and groove is the width and the alignment pin radius sum of 1/2nd grooves, another alignment pin between two grooves, the width that surpasses two grooves at interval with first alignment pin circular arc and alignment pin diameter with.

The alignment pin axis is vertical mutually, and two alignment pins are the width and the alignment pin radius sum of 1/2nd grooves with the vertical radial distance in the endoporus center of circle.Make things convenient for the processing of alignment pin to install, the working position of anchor clamps is in the center on pressure-bearing plane, and working position is stressed evenly.

" following Kong Weiyi big hole internal diameter is more bigger than the internal orifice dimension of brake disc, and external diameter is less than the required machining hole of brake disc place " of the present utility model is the boring of oil cylinder and brake disc not to be produced interference in order to push down brake disc.The utility model has two relative protrusions according to present oil cylinder pressure head top, anchor clamps are put into the oil cylinder pressure head, revolve and turn 90 degrees, the second layer endoporus of anchor clamps boss blocks the protrusion at oil cylinder pressure head top, promptly can carry out holding workpiece, the spacing of an alignment pin is that anchor clamps can be inserted in the oil cylinder pressure head smoothly, and another alignment pin is the working position that guarantees anchor clamps, easy to operate, quick, reduced labour intensity.Because the whole anchor clamps that are inserted in of oil cylinder pressure head have been eliminated the hidden danger that operating personnel are weighed wounded by the oil cylinder pressure head.Because the utility model is the jacket casing formula, anchor clamps are not subjected to the restriction of brake disc internal diameter, and effect is identical with mode commonly used, and does not influence efficient, can conveniently play clamping action.
