Embodiment approach

[0023] As an embodiment of the present invention, the sliding block 44 is fixedly connected with a rubber pad 46 on the outer surface of the positioning column 23; a reinforcing rod 47 is evenly arranged inside the rubber pad 46; the reinforcing rod 47 has two guide rods When working, the motor 45 rotates so that the hinge plate 42 pushes the sliding block 44 to squeeze the inner wall of the steering machine housing, and then fixes the steering machine housing. Outside the third chute 43 of the sliding block 44 When the displacement occurs, the rubber pad 46 fixed on the surface of the sliding block 44 first contacts the inner wall of the through hole of the steering gear housing. At the same time, with the continuous displacement of the sliding block 44, pressure is gradually exerted on the rubber pad 46. 47 first generates pressure with the inner wall of the through hole of the steering machine housing, and as the pressure increases, the reinforcing rod 47 gradually rotates a...

Abstract

The invention belongs to the technical field of machining fixtures, and particularly relates to an automobile steering machine shell arm hole boring fixture. The automobile steering machine shell armhole boring fixture comprises a base, a fixed plate and a moving plate; the fixed plate is fixedly connected to the upper surface of the base; a limiting block is embedded into one side of the fixed plate; a positioning column is slidably connected to the interior of a first sliding groove; the moving plate is installed on the side, far away from the fixed plate, of the upper surface of the base;a guiding rod is fixedly connected to the surface of the side, close to the fixed plate, of the moving plate; an auxiliary ring is slidably connected to the guiding rod; a second sliding groove is formed in the positioning column; a rotating roll is rotatably connected to the interior of the second sliding groove; hinge plates which are evenly arranged are hinged to the surface of the rotating roll; the surface of the positioning column is provided with third sliding grooves which are evenly formed; sliding blocks are slidably connected to the interiors of the third sliding grooves; and the sliding blocks are hinged to the hinge plates. According to the automobile steering machine shell arm hole boring fixture, the positioning column penetrates through a through hole of a steering machineshell and fixes the steering machine shell in the through hole, and then the whole steering machine shell is clamped.

Description

technical field [0001] The invention belongs to the technical field of machining fixtures, in particular to a boring fixture for an arm hole of a housing of an automobile steering gear. Background technique [0002] The device used to fix the processing object in the process of mechanical manufacturing so that it occupies the correct position to accept construction or inspection, also known as fixture. In a broad sense, any process in the process, the device used to install the workpiece quickly, conveniently and safely, can be called a fixture. Such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. Among them, machine tool fixtures are the most common, often referred to as fixtures. During the processing of the engine bearing cover, in order to make the surface of the workpiece meet the technical requirements of the size, geometric shape and position accuracy with other surfaces specified in the drawing, the workpiece must be install...
