Abstract

The utility model provides a geometric tolerances examines utensil, respectively is equipped with a movable center including inspection platform, saddle and locating piece, four bights in bottom surface of the above -mentioned inspection platform of its characterized in that, the saddle sets up at the inspection platform on the surface with outer hex bolts fixed mounting, hexagon socket head cap screw fixed mounting sets up on the saddle for the locating piece, the inspection platform still be provided with the magnetic force gauge stand on the surface, be equipped with the support on the gauge stand, the support facial make -up is equipped with the percentage table, this percentage table corresponds with the locating piece for the axiality of circle and locating hole in detecting, the beneficial effects are that through the cooperation of locating piece and end cover, manually rotate the end cover, the percentage table that reuses is measured can draw the concentricity size, and to compare the precision similar with traditional three -coordinate inspection appearance, and it is with low costs that nevertheless this examines the utensil, convenient to use, and not high to operation workman technical requirement, the specially adapted medium -sized and small enterprises detect geometric tolerances's the utensil of examining.

Description

A kind of form and position tolerance cubing

Technical field

The utility model relates to machinery manufacturing industry form tolerance or position of related features detects the simple high-precision morpheme form and position tolerance cubing of using measurer technical field, particularly a kind of convenient operation.

Background technology

Existing a lot of middle-size and small-size Mechanical Manufacturing Enterprises, because there is no the unable purchase of sufficient fund three-dimensional detector up to a million, cannot carry out form and position tolerance detection to produced parts, can only lean on process equipment or technique to ensure, not have professional inspection apparatus cannot ensure at all and produce qualified parts.

Three-dimensional detector complicated operation, high to operator's technical requirement simultaneously, also seriously restricted middle-size and small-size Mechanical Manufacturing Enterprises and used.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of easy form and position tolerance cubing of convenient operation cheaply for the problems referred to above, to reduce enterprise's production cost, ensures the qualification rate of parts.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is a kind of form and position tolerance cubing, comprises verifying bench, saddle and locating piece, it is characterized in that the Si Ge bight, bottom surface of above-mentioned verifying bench is respectively provided with a rolling center; Saddle is arranged on the surface of verifying bench with the fixed installation of outer-hexagonal bolt; Locating piece is arranged on saddle with hexagon socket head cap screw fixed installation; On the surface of verifying bench, be also provided with magnetic stand, gauge stand is provided with support, is equiped with dial gauge on support, and this dial gauge is corresponding with locating piece, for detection of the axiality of inner circle and locating hole.

Described verifying bench is datum plane, and its flatness is 0.04mm, and roughness is 0.8um.

Described saddle is smart datum level, and the depth of parallelism of its both ends of the surface is 0.005mm, and roughness is 0.8um.

Described locating piece is positioning datum, and the perpendicularity of its lower surface and cylindrical is 0.005mm, and roughness is 0.8um.

The beneficial effects of the utility model are coordinating by locating piece and end cap, manual rotation end cap, re-use dial gauge measurement and can draw concentricity size, low precision is few compared with traditional three-dimensional detector, but this cubing cost is low, easy to use, not high to operator's technical requirement, be specially adapted to medium-sized and small enterprises and detect the cubing of form and position tolerance.

Brief description of the drawings

Accompanying drawing is overall structure schematic diagram of the present utility model.

In figure: 1. verifying bench, 2. saddle, 3. locating piece, 11. rolling centers, 21. outer-hexagonal bolts, 31. hexagon socket head cap screws, 4. magnetic stand, 41. supports, 42. dial gauges, 5. tested end cap.

Detailed description of the invention

Below in conjunction with embodiment, the utility model is described in further detail.

As shown in Figure 1, make a kind of form and position tolerance cubing, first verifying bench 1 is installed, a rolling center 11 of each installing in Si Ge bight, the bottom surface of verifying bench 1, smooths verifying bench 1 with rolling center 11, using this by verifying bench 11 as reference platform slightly; Then saddle 2 use outer-hexagonal bolt 21 fixed installations are arranged on the surface of verifying bench 1, as smart reference platform; Again locating piece 3 use hexagon socket head cap screw 31 fixed installations are arranged on saddle 2; Magnetic stand 4 is also installed in addition on the surface of verifying bench 1, support 41 is set on gauge stand 4, on support 41, install dial gauge 42, and make dial gauge 42 corresponding with locating piece 3, for detection of the axiality of inner circle and locating hole.

In the present embodiment, the flatness of verifying bench 1 is become to 0.04mm, roughness becomes 0.8um; The depth of parallelism of the both ends of the surface of saddle 2 is become to 0.005mm, and roughness becomes 0.8um; The perpendicularity of the lower surface of locating piece 3 and cylindrical is become to 0.005mm, and roughness becomes 0.8um.

When use, as shown in Figure 1, electric motor end cap 5 is placed on locating piece 3, the gauge head of dial gauge 42 is installed on the internal circular surfaces of tested end cap 5, rotary end cover rotates 360 ° for 5 one weeks gently, in rotation process, read dial gauge 42 maximum jitter data, fetched data, divided by 2, is the decentraction size of the inner circle of tested end cap 5.
