Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] The present invention is a special boring fixture for machining brake air chamber bracket parts, comprising a bottom plate 2 , a clamping mechanism 7 and a transverse plate 3 .

[0023] like Figure 1 to Figure 5 As shown, the bottom plate 2 is installed on the connecting plate 1, and one end of the bottom plate 2 is mounted with a fixing block 6, and the fixing block 6 is provided with a fastener. In this embodiment, the fastener is the second screw 5 , the fixing block 6 is symmetrically arranged on the bottom plate 2 , and the fastener is arranged on the fixing block 6 parallel to the horizontal plane. The tails of the fasteners on the symmetrical fixing blocks 6 are arranged opposite each other. The inner thread on the fixing block 6 is matched with the outer thread on the fastener.

[0024] The horizontal plate 3 is installed on the other end o...

Abstract

The invention relates to the technical field of clamps for machining automobile brake parts and particularly discloses a boring clamp special for brake chamber support part machining. The boring clampspecial for brake chamber support part machining comprises a bottom plate, a clamping mechanism and a transverse plate, wherein a fixed block is mounted at one end of the bottom plate; a fastener isarranged on the fixed block in a penetrating mode; the transverse plate is mounted at the other end of the bottom plate; a hole is formed in the middle of the transverse plate; side positioning supports are arranged at the two ends of the transverse plate; the clamping mechanism is installed on the bottom plate; the clamping mechanism comprises a fixed screw rod, a pressing block assembly and a movable screw rod; one end of the pressing block assembly is rotatably connected with the fixed screw rod; and the other end of the pressing block assembly movably penetrates through the movable screw rod. Two-side precision hole machining can be completed through one-time clamping, and the machining efficiency and the machining precision are improved.

Description

technical field [0001] The invention relates to the technical field of jigs used for processing automobile brake parts, in particular to a special boring jig for processing brake air chamber bracket parts. Background technique [0002] The brake air chamber is also called the brake cylinder, and its function is to convert the pressure of the compressed air into a mechanical force that rotates the brake camshaft, so that the camshaft pushes the friction plate in the brake shoe assembly to contact the brake drum, Realize the braking action of the car. The air chamber bracket has two main functions, one is to connect the brake air chamber and the axle, to ensure that the thrust output from the brake air chamber is transmitted to the axle braking system in a certain form, and the other is to locate and install the brake system. Move the camshaft and ensure the rotation of the brake camshaft. [0003] In the prior art, when machining the rear bracket of the brake air chamber, t...
