Abstract

The utility model relates to a special fine grinding squeeze tool for a sheet copper in a fuel oil corrosion test method. A binding bolt hole is arranged on a rear plywood (1) and a front plywood (2); a slideway (1-1) is arranged on a pedestal of the rear plywood (1); the front plywood (2) is arranged on the slideway on the pedestal of the rear plywood (1); a binding bolt (5) is arranged in the binding bolt hole of the rear plywood (1) and the front plywood (2); a left plywood (3) and a right plywood (4) are respectively arranged at the left and the right sides between the rear plywood (1) and the front plywood (2). The special fine grinding squeeze tool has the advantages that the work, the time and the labor are saved by using a grinding tool, and the abrasion damage on the fingers is avoided; the surface of the grinding sheet copper is uniform, smooth, sheeny, and level, the possibility that the sheet copper contacts with the fingers is reduced, and the accuracy of the testing is increased.

Description

The special-purpose copper sheet fine gtinding of fuel oil etching test anchor clamps

Technical field

The utility model relates to the machining tool field.

Background technology

At present will do corrosion test with the copper sheet of special use when the corrosivity of fuel oil is measured, the surface smoothness of copper sheet is high more, and the degree of accuracy of test is high more.During test, to test the sixth of the twelve Earthly Branches to be that No. 180 sand paper is done meticulous grinding (also must be No. 150 coated abrasive working in advance with granularity during to new copper sheet) with granularity with the copper sheet of mistake.In process of lapping, all all will rely on hand directly to hold copper sheet and grind on sand paper and finish, labour intensity is big, time-consuming effort, and grind copper sheet for a long time, not only cause the finger breakage to fray easily, and rely on hand directly to hold the copper sheet grinding, the copper sheet surface smoothness of grinding is even inadequately, influences accuracy of test.Directly hold copper sheet with hand simultaneously and can pollute copper sheet, also can influence accuracy of test.

The utility model content

The purpose of this utility model is exactly at the above-mentioned deficiency of existing fuel oil etching test special purpose copper slice lapping mode, and the special-purpose copper sheet fine gtinding of a kind of fuel oil etching test anchor clamps are provided, it is by rear plate 1, front plate 2, left side clamping plate 3, right clamping plate 4, fastening bolt 5 is formed, be provided with the fastening screw keyhole on the rear plate 1 He on the front plate 2, on the base of rear plate 1, be provided with slideway 1-1, front plate 2 is placed on the slideway of rear plate 1 base, fastening bolt 5 is installed in the fastening screw keyhole of rear plate 1 and front plate 2, and left clamping plate 3 and right clamping plate 4 are placed in the left side between rear plate 1 and the front plate 2 respectively, right both sides.

The utility model has the advantages that: use this grinding tool, saving of work and time is laborsaving, can avoid finger to fray.The copper sheet surface of grinding is uniform and smooth, bright, smooth, has reduced copper sheet and the chance that finger contacts, and can improve accuracy of test.

Description of drawings

Accompanying drawing 1 is the utility model structural representation.Accompanying drawing 2 is the rear plate structural representation.Accompanying drawing 3 is the structural representation of right clamping plate and left clamping plate.

The specific embodiment

All parts are all processed with copper material, opening 2 tapped fastening screw keyholes respectively on the rear plate He on the front plate, on the base of rear plate, establish two slide rails, open two chutes in the front plate bottom surface, front plate is placed on the slide rail of rear plate base by chute, 2 fastening bolts are installed in the fastening screw keyhole of rear plate and front plate, and left clamping plate and right clamping plate are placed in the left and right both sides between rear plate and the front plate respectively.

During use, copper sheet 6 is placed between rear plate, front plate, left clamping plate and the right clamping plate, copper sheet 6 is clamped by fastening bolt.Hold the base plate of rear plate, copper sheet 6 be placed on the sand paper grind, ground a face after, loosening fastening bolt changes a face with copper sheet 6, until 6 faces of copper sheet 6 all grind smooth till, fineness is measured by color board.Should avoid hand directly to contact in the operation with copper sheet.

Claims

1, the special-purpose copper sheet fine gtinding of fuel oil etching test anchor clamps, it is characterized in that it is by rear plate (1), front plate (2), left side clamping plate (3), right clamping plate (4), fastening bolt (5) is formed, upward and on the front plate (2) be provided with the fastening screw keyhole at rear plate (1), on the base of rear plate (1), be provided with slideway (1-1), front plate (2) is placed on the slideway of rear plate (1) base, fastening bolt (5) be installed in rear plate (1) and front plate (2) tightly with in the bolt hole, left clamping plate (3) and right clamping plate (4) are placed in the left side between rear plate (1) and the front plate (2) respectively, right both sides.
