Technical Field

The utility model belongs to the technical field of machining clamp equipment, and particularly relates to an air floating tool.

Background

At present, when processing big work piece hole, the work piece is because bulky, lead to it to find the focus easily at the in-process of centre gripping processing, make the unable complete concentricity or the decentraction in center of cutter and work piece, thereby make the circularity of the product that processes out, concentricity, cylindricity and parallelism etc. effect all the super poor, it can't satisfy the accurate processing requirement of production drawing, cause the product to have the production poor quality, the yields is low, defective products consumptive material with high costs, production efficiency is low and productivity low grade is not enough, it does not conform to the requirement of enterprise high-efficient production and high-quality production.

The utility model provides an air floating tool jig which effectively solves the problems.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model aims to provide an air floating tool jig, which solves the background technical problem.

The specific technical scheme is as follows:

the utility model has the beneficial effects that: according to the utility model, the floating plate is vertically and slidably mounted on the air floating bottom plate, the air cavity is arranged in the air floating bottom plate, the air outlet hole is formed in the upper surface of the air floating bottom plate, the floating plate is floated by inflating the air cavity into the air cavity, the steel ball sliding sleeves are fixedly mounted on two sides of the floating plate, so that the floating plate can only float up and down in the clearance range between the steel balls in the steel ball sliding sleeves and the bottom wall of the air floating bottom plate, a workpiece is clamped on the floating plate, and the cutter and the clamped part can be automatically and accurately aligned, and the machining precision is high, the machining effect is good, and the yield is high.

And the steel sliding sleeve enables the floating plate to be translated and cleared.

Detailed Description

The foregoing and other aspects, features and advantages of the present invention will become more apparent from the following detailed description of the embodiments with reference to the accompanying drawings, which is set forth in part in the accompanying drawings of fig. 1-5. The following examples are given to illustrate the structures and to be referred to in the drawings.

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

In order to solve the problems in the prior art, the embodiment provides an air-floating tooling fixture, which comprises an air-floating bottom plate 1, wherein limiting pins 3 are symmetrically and fixedly installed at the left side and the right side of the upper end of the air-floating bottom plate 1, a floating plate 2 is placed on the air-floating bottom plate 1, pin holes vertically matched with the limiting pins 3 in a sliding manner are formed in the lower end of the floating plate 2, an air cavity 4 is arranged in the floating plate 2, the air cavity 4 comprises two through holes transversely arranged in the air-floating bottom plate 1 and a through hole longitudinally arranged in the air-floating bottom plate 1, the processing is convenient, the two transverse through holes are communicated with the longitudinal through hole, two ends of the two transverse through holes and one end of the longitudinal through hole are blocked, only one air inlet hole is reserved, 4 air outlet holes 5 communicated with the air cavity 4 are formed in the upper surface of the air-floating bottom plate 1, the 4 air outlet holes 5 are uniformly distributed in the middle of the upper surface of the air-floating bottom plate 1 in a rectangular manner, wherein the two air outlet holes 5 are positioned at the communicated parts of the longitudinal through hole and the two transverse through holes, and the diameters of all the air outlet holes 5 are smaller than the diameter of the through hole, and the upper end of the floating plate 2 is detachably provided with a workpiece positioning sleeve 7.

The left side and the right side of the air floatation bottom plate 1 are provided with bosses, the left side and the right side of the floating plate 2 are fixedly provided with ball sliding sleeves 6, a plurality of steel balls arranged at intervals are contained in the ball sliding sleeves 6, and all the steel balls are in clearance fit with the bottom ends of the bosses.

All be equipped with the mounting hole around the air supporting bottom plate 1 for the installation of air supporting bottom plate 1.

The specific use process of the embodiment is as follows:

the air cavity 4 is inflated through the air inlet, the floating plate 2 floats, the moving range of the floating plate 2 is controlled through the limiting pin 3, the floating range is a gap between the steel ball and the bottom wall of the boss, the steel ball enables the floating plate 2 to slide smoothly all around on the air floating bottom plate 1, workpieces are clamped on the floating plate, and automatic and accurate alignment of bulky products (cutters) and parts after clamping can be achieved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
