Detailed Description

The utility model will be further described with reference to the accompanying drawings, without limiting the scope of the utility model to the following:

as shown in fig. 3 to 7, a tooling fixture for improving the CNC machining precision of a plurality of products comprises a bottom plate 3 and a gland 4, wherein the top surface of the bottom plate 3 is provided with front and rear edges thereof with front and rear spigots 5, the two spigots 5 on the bottom plate 3 are symmetrically arranged in front and rear directions, the top surface of the bottom plate 3 is provided with a plurality of sinking grooves 6 for accommodating Z-shaped plates 1 along the length direction of the spigots 5, the distance between the two adjacent sinking grooves 6 is equal, the depth of each sinking groove 6 is equal to the thickness of the Z-shaped plate 1, each sinking groove 6 penetrates through the vertical surface of the spigot 5, the horizontal surface of the spigot 5 is provided with a plurality of clearance grooves 7 corresponding to the sinking grooves 6 along the length direction thereof, the distance between the two adjacent clearance grooves 7 is equal, the top surface of the bottom plate 3 is provided with a plurality of threaded holes 8, the bottom surface of the gland 4 is provided with a pressing block 9 corresponding to the sinking grooves 6, a plurality of through holes corresponding to the threaded holes 8 are formed in the gland 4, a screw 10 is embedded into each through hole, and the screw 10 is perpendicular to the gland 4. The threaded holes 8 are arranged along the length of the base plate 3.

The working process of the utility model is as follows:

s1, placing a Z-shaped plate 1 of a product in each sinking groove 6 by a worker to realize the positioning of the tool of the product as shown in figures 8-9, wherein the support plate 2 of the product is suspended right above the corresponding avoiding groove 7, namely burrs on the bottom surface of the support plate 2 are just in the avoiding groove 7, and the top surfaces of the support plates 2 are all on the same horizontal plane;

s2, a worker places the bottom plate 3 on a tooling table of the numerical control machining system, and fixes the gland 4 by adopting a pressing mechanism, so that the fixture is fixed;

s3, covering the gland 4 on the top surface of the bottom plate 3 by a worker, connecting the screw 10 with the threaded hole 8 on the bottom plate 3 in a threaded manner, positioning the gland 4, and respectively and correspondingly pressing the pressing blocks 9 on the bottom surface of the gland 4 on the top surface of each Z-shaped plate 1 under the threaded connection force of the screw 10 and the threaded hole 8, so that the Z-shaped plates 1 are fixed, and further, each product is fixed as shown in FIGS. 10-11; therefore, a plurality of products can be fixed by the tool in the front and rear sinking grooves 6 of the bottom plate 3, and compared with the traditional fixture, the fixture can only fix a plurality of products, so that the production efficiency of finished products is greatly improved.
