Abstract

The utility model discloses a leather tensile test's general clamping device, including two sets of anchor clamps, every set of anchor clamps include base, bracing piece, U type anchor clamps, scale micrometer, left side fixed block, left side clamp plate, right side clamp plate, right side fixed block, micrometer handle, the bracing piece fastening is installed on the base, U type anchor clamps are installed on the bracing piece, and left side fixed block and the fastening of right side fixed block are on U type anchor clamps, the scale micrometer has on left side fixed block and the right side fixed block, the micrometer handle is installed at scale micrometer tip, two sets of anchor clamps U type anchor clamps are at a distance of the symmetry installation, put into the one end of leather sample between left side clamp plate and the right side clamp plate, the scale micrometer of anchor clamps about the adjustment, it is the same to make it the reading, and the micrometer handle of two sets of anchor clamps of individual adjustment makes the clamp plate press from both sides tight leather sample, and the sample is pressed from both sides tightly in vertical orientation. The advantage: the clamp is tightly operated accurately, the sample is pressed from both sides tightly in vertical direction, the atress is even, the splint surface can be better yu softer leather substance laminating.

Description

A kind of leather tensile strength tests general clamping device
Technical field
This utility model belongs to experimental technique field, relates to the general clamping device of a kind of leather tensile strength test, particularly relates to the general clamping device of a kind of steering wheel leather tensile strength test.
Background technology
Steering wheel leather tensile strength is tested, if clamping force is too small, sample can be caused to slip, if clamping force is excessive, sample can be caused to rupture along clamp edges.Owing to leather is softer, sample stress can be caused in the case of upper lower clamp misaligns not vertical, elongation percentage measured value is inaccurate.
Summary of the invention
The utility model discloses the general clamping device of leather tensile strength test, too small to solve clamping force in prior art, sample can be caused to slip, if clamping force is excessive, sample can be caused to rupture along clamp edges;Sample stress is not vertical, the problems such as elongation percentage measured value is inaccurate.
This utility model includes that two sleeve clamps, every sleeve clamp include base, support bar, U-shaped fixture, scale micrometer, left side fixed block, left side pressing plate, right side pressing plate, right side fixed block, micrometer handle;Support bar is securedly mounted on base;U-shaped fixture is arranged on support bar, and left side fixed block and right side fixed block are fastened on U-shaped fixture;On left side fixed block and right side fixed block, there is scale micrometer;Micrometer handle is arranged on scale micrometer end;The two U-shaped fixtures of sleeve clamp are apart symmetrically installed;Being put into one end of leather sample between left side pressing plate and right side pressing plate, in adjustment, the scale micrometer of lower clamp, is allowed to reading identical, adjusting the micrometer handle of two sleeve clamps respectively, make platen clamp leather sample, sample is clamped at vertical direction, thus uniform force, complete sample clamping.
The every sleeve clamp of this utility model also includes that nut fixed by axle sleeve, axle sleeve alignment pin, axle sleeve;Axle sleeve coordinates with support bar;Axle sleeve alignment pin is arranged on axle sleeve and support bar, is matched in clearance with hole, location, spacing to axle sleeve;Axle sleeve is fixed nut and is arranged on enhancing locking axle sleeve below axle sleeve.
The every sleeve clamp of this utility model also includes that base fixes nut, U-shaped fixture fixes nut, U-shaped clamp locating pin;Support bar screw threads for fastening is arranged on base;Base is fixed nut and support bar is strengthened locked being fixed on base;U-shaped fixture is fixed nut and is arranged on below U-shaped fixture and locks U-shaped fixture;
On the left of this utility model, pressing plate, right side pressing plate are wave convex surfaces with the contact surface of sample, it is possible to preferably with softer leather substance laminating.
Left side press plate position on U-shaped fixture can pass through scale mike, the size positions of registration.
Of the present utility model having the active effect that positions and fixing leather test specimen, splint position readable, and clamp operation is accurate;Sample is compressed by adjustable two side guide, and pressing plate is the most vertical with horizontal axis, it is ensured that sample is clamped at vertical direction, uniform force;Cleat surface is wave convex surfaces, it is possible to preferably with softer leather substance laminating;There is the strongest practicality.
Accompanying drawing explanation
Fig. 1 is this utility model structural front view;
Fig. 2 is this utility model structural side view;
Fig. 3 is this utility model structural upright structural representation;
In figure: 1 base, 2 nuts, 3 support bars, 4 nuts, 5 axle sleeves, 6 nuts, 7 U-shaped fixtures, 8 scale micrometers, left 9 side fixed blocks, pressing plate on the left of 10, pressing plate on the right side of 11, fixed block, 13 handles, 14 alignment pins, 15 alignment pins on the right side of 12.
Detailed description of the invention
An embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
This utility model embodiment includes two sleeve clamps, as shown in Figure 1, Figure 2, Figure 3 shows, every sleeve clamp includes that base 1, base fix nut 2, nut 4 fixed by support bar 3, axle sleeve, axle sleeve 5, U-shaped fixture fix nut 6, U-shaped fixture 7, scale micrometer 8, left side fixed block 9, left side pressing plate 10, right side pressing plate 11, right side fixed block 12, micrometer handle 13, U-shaped clamp locating pin 14, axle sleeve alignment pin 15.Support bar 3 is tightened on base 1, and base fixes nut 2 locked fastening support bar 3;Axle sleeve 5 is arranged on support bar 3, inserts axle sleeve alignment pin 15, and fixes nut 4 with axle sleeve and fasten;U-shaped fixture 7 is arranged on support bar 3, inserts U-shaped clamp locating pin 14 and fixes nut 6 with U-shaped fixture and fasten;Left side fixed block 9 and right side fixed block 12 are fastened on U-shaped fixture 7.A set of clamp base 1 makes to be fixed by bolts on puller system platform, and this fixture another set of is fixed on the crossbeam of puller system, forms upper and lower fixture.
