Description

Fixture for Reverse Positioning Drilling of Swing Arm

technical field

The utility model relates to a clamping and fixing device, in particular to a clamp used for reverse positioning drilling of a rotary arm and processing of inclined holes.

Background technique

There is an included angle between the top and the bottom of the swivel arm. Since the top of the swivel arm needs to be drilled to install other components, but the angle between the top and the bottom of the swivel arm is set, so the hole needs to be drilled obliquely, which increases the Difficulty in processing increases the cost, so there is an urgent need on the market for a fixture that can quickly and firmly clamp the slewing arm to facilitate quick drilling of holes on its top.

Utility model content

The utility model aims to solve the above-mentioned shortcomings of the prior art, and provides a fixture that can quickly and stably clamp and fix the slewing arm and can conveniently process the oblique hole on the slewing arm. The need for high drilling efficiency.

The technical solution adopted by the utility model to solve the technical problem: the fixture used for the reverse positioning drilling of the rotary arm, including the fixture base, the top surface of the fixture base is fixed with a fixed seat one, and the inner surface of the fixed seat one A positioning boss is fixed, and the outer end surface of the placing boss is a plane. The outer surface of the placing boss is fixed with a positioning column. The positioning column is fixed with a threaded rod. The anti-skid nut, the top surface of the fixture base is fixed with threaded rod two, the threaded rod two is threadedly connected with a support block, the top of the inner side of the fixed seat one is fixed with the fixed seat two, and the fixed seat two is fixed with an outwardly extending The limiting plate of the fixed seat two, the bottom surface of the limiting plate is plane two. The role of placing the boss and plane 1 here is to place the A datum plane of the workpiece; the role of the positioning column here is to install the positioning hole of the workpiece, so as to facilitate the installation of the workpiece; here, the threaded rod 1 and the gasket 1. The function of the anti-skid nut is to turn the anti-skid nut and use the gasket to press the workpiece on the resting boss; here the function of the limit plate and plane 2 is to fit the B datum plane of the workpiece; here the support block, The function of the threaded rod 2 is to press the bottom of the workpiece so that the B reference plane of the workpiece is pressed against the plane 2 of the limit plate, and prevent the workpiece from rotating when the hole is to be drilled, so as to facilitate the vertical drilling of the hole to be drilled out.

For further improvement, a through hole is opened on the limiting plate, and a drill sleeve is installed on the through hole. The role of the drill sleeve here is to guide the drill bit, thereby improving the machining accuracy of the hole to be drilled.

For further improvement, a nut 1 is fixed on the bottom of the support block, and the nut 1 is threadedly connected to the threaded rod 2. Here the effect of nut one is to facilitate the screwing of the support block.

For further improvement, the threaded rod 2 is threaded with a nut 2. The effect of the nut two here is, after the support block pushes the column workpiece tightly, utilize the nut two to be tightened on the nut one, can prevent the situation that the support block becomes loose.

The beneficial effects of the utility model are: the structure design of the utility model is ingenious and reasonable, the positioning hole of the workpiece can be installed first by using the positioning column, and the workpiece can be moved until the A reference surface of the workpiece fits on the plane where the boss is placed , and then rotate the workpiece so that the B reference surface of the workpiece fits on the plane two of the limit plate. In order to prevent the workpiece from rotating when being processed, screw the nut 1 so that the support block is pressed against the bottom of the workpiece. Tighten the B datum plane of the workpiece on the two planes of the limit plate, so as to prevent the workpiece from rotating when being processed, so that it is convenient to drill the oblique hole on the workpiece with the drill bit installed vertically, and the operation is simple. The processing efficiency is high, and it is worth popularizing and applying.
