Description

Fixed convenient stable G type anchor clamps

Technical Field

The utility model belongs to the metal machinery field, concretely relates to fixed convenient stable G type anchor clamps.

Background

The assembly fixture is indispensable in the production process of products, and is an important tool for safely and freely carrying out assembly operation and ensuring the product quality. The G type anchor clamps are exactly one commonly used, and traditional G type anchor clamps's structure and function include that the G presss from both sides the clamp, are I shape bow one end at the cross section and are equipped with the screw, and the other end is equipped with the briquetting, is equipped with the lead screw through the screw, and lead screw one end is equipped with the handle, and the other end is equipped with the briquetting. The handle is movably sleeved at the end part of the screw rod, so that the power arm can be enlarged. When the device is used, the handle is rotated to enable the screw rod to drive the pressing blocks, and the distance between the two pressing blocks is adjusted. The structure has little problem on clamping wood boards or objects with soft texture, but has a great problem when clamping hard objects, the reaction force of the hard objects to the clamp is great, and the traditional G-shaped clamp has the possibility of displacement.

Disclosure of Invention

The purpose of the invention is as follows: an object of the utility model is to provide a fixed convenient stable G type anchor clamps to prior art not enough.

The technical scheme is as follows: in order to achieve the above object, the present invention is specifically realized as follows: a G-shaped clamp convenient and stable to fix comprises a C-shaped body, wherein one end of the C-shaped body is provided with a contact surface, and the other end of the C-shaped body is a hollow pipe; the hollow pipe is provided with internal threads, the end of the hollow pipe close to the contact surface is connected with a first hollow pipe through threads, a T-shaped hollow pipe with a threaded cavity is arranged in the first hollow pipe, a screw rod is arranged in the T-shaped hollow pipe, and a rectangular clamping surface is arranged at the end part of the screw rod close to the contact surface; the other end of the hollow pipe is connected with a second hollow pipe through threads, the second hollow pipe is provided with a pair of parallel extending surfaces, a pair of parallel through holes are correspondingly formed in the extending surfaces, a rotating shaft with a fixing hole is arranged between the two extending surfaces, and the rotating shaft and the extending surfaces are fixed with through rivets in the through holes through the fixing holes; the rotating shaft is cylindrical, and one side of the rotating shaft is provided with a plane which is tangent to the circumference of the cylinder; the rotating shaft is connected with a handle through riveting.

The fixed hole is positioned in the center of the rotating shaft, and a connecting line of the fixed hole and a point on the central line of the plane of the rotating shaft is the same as the radius of the circular cylindrical section; the length of the connection between the fixing hole and a point on the non-central line of the plane of the rotating shaft is longer than the radius of the circular cylindrical section.

The utility model discloses specific during operation, with the article as for between this body contact surface and the lead screw clamping face, lead screw and T type hollow tube close soon as possible, then rotatory to plane department towards the hollow tube with the pivot, make T type hollow tube tip push away to with pivot plane contact this moment, then accommodate the lead screw distance make lead screw clamping face and this body contact surface with the firm centre gripping of article.

Has the advantages that: compared with the prior art, the utility model, have following advantage:

(1) the utility model has simple structure and scientific design, can fix the clamp and the object to be measured for a long time, and the object to be measured can not move, thereby greatly improving the stability of the clamp;

(2) the utility model discloses T type hollow tube is the biggest with the lead screw atress during the use, even appear the screw thread damage, also only need change both or even one of them, cost of maintenance is low.
