Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing tooling, in particular to a tooling for detecting the spatial dimension and shape and position tolerance of a rack. Background Art

[0002] The bottom and top surfaces of the tested bracket have parallelism accuracy, and the four corners of the lower end of the tested bracket are respectively provided with raised supporting feet, and the relative positions of the supporting feet also have position accuracy. Four groups of holes are opened at the four corners of the upper end of the tested bracket, and the position accuracy also needs to be controlled. The existing technology uses a three-coordinate measuring instrument to measure when testing these accuracy. Since the three-coordinate test is relatively cumbersome and requires specialized technicians to perform the test, it greatly wastes manpower and time. Utility Model Content

[0003] The utility model provides a tool for detecting the spatial dimension and shape and position tolerance of a rack, which is used to solve the problems raised by the background technology.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a tool for detecting spatial dimensions and form and position tolerances of a hanger, comprising a base plate, wherein both sides of the upper end of the base plate are fixedly connected to vertical supports, and the front and rear sides of the vertical supports are fixedly connected to horizontal supports, and a plurality of groups of recessed U-shaped grooves are provided on the side of the base plate, and the bottom surfaces of the U-shaped grooves are on the same horizontal line, and the upper ends of the vertical supports are fixedly connected to a top plate, and a positioning pin shaft hole is provided on the upper end of the top plate, and the upper surface of the base plate and the upper surface of the top plate are parallel to each other.

[0005] Preferably, grooves are provided at the four corners of the upper end of the bottom plate, the U-shaped grooves.

[0006] Preferably, the vertical supports are symmetrically arranged on both sides of the base plate.

[0007] Preferably, the vertical supports and the horizontal supports are hollow structures composed of rectangular square tubes.

[0008] Preferably, there are four groups of positioning pin shaft holes, and two groups of positioning pin shaft holes are provided on the upper end of each group of top plates.

[0009] Preferably, the upper surface of the bottom plate and the upper surface of the top plate are parallel to each other, and the roughness of both is 0.8.

[0010] Preferably, the base plate and the vertical support are fixedly connected via a connecting plate.

[0011] Preferably, the vertical support side surfaces are fixedly connected to reinforcing ribs, and the lower ends of the reinforcing ribs are fixedly connected to the connecting plates.

[0012] Beneficial effects of the utility model:

[0013] The tooling of the utility model replaces the three-coordinate detection. When performing the detection, the bracket to be detected is placed in the tooling of the utility model, and four groups of positioning pin holes are connected by pin shafts. The pin shaft connection can directly detect the four groups of holes opened at the four corners of the upper end of the bracket to be detected and the supporting feet at the four corners of the lower end of the bracket to be detected. Then, a feeler gauge is used to measure the gap between the bottom surface and the top surface of the bracket to be detected and the tooling, so as to determine the flatness between the bottom surface and the top surface of the bracket to be detected. By adopting the tooling of the utility model, the bracket to be detected can be detected quickly, which greatly saves time and manpower. BRIEF DESCRIPTION OF THE DRAWINGS
