Description

Clamp device

Technical Field

The utility model relates to a mounting fixture field particularly, relates to a fixture device, especially the fixture device of pulling force machine.

Background

In the process of manufacturing the copper foil by electrolysis, the copper foil produced by electrolysis can meet the use requirements of downstream industries only if the copper foil reaches certain strength and toughness. In this case, physical properties such as tensile strength and elongation of the copper foil product need to be measured.

The anchor clamps surface that most pulling force machines used at present is metal material or plastics material, and the surface is comparatively smooth, and copper foil product surface is also comparatively smooth, and the slip appears easily in the copper foil when pressing from both sides tight back start-up, and during the twist grip, the slider easily rotates along with the rotation of handle, leads to the sample to be in the distortion state, and receives the difference of operating personnel gimmick, influences the measuring result.

An effective solution to the problems in the related art has not been proposed yet.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned technical problem among the correlation technique, the utility model provides a fixture device can solve above-mentioned problem.

In order to achieve the technical purpose, the technical scheme of the utility model is realized as follows:

a clamp device comprises a rotating handle, a pin fixing base, a clamp fixing knob and a clamping block. The clamp fixing knob is fixed below the fixing base through two different fixing bolts and fixing bolts, and the clamping block is fixed below the clamp fixing knob through three hexagon socket head cap bolts and hexagon socket head cap bolts; two pins are inserted into one side of the clamping block and fix the rotating handle.

Furthermore, the diameter of one fixing bolt is larger than that of the other fixing bolt.

Furthermore, the diameter of one hexagon socket head cap screw is larger than that of the other hexagon socket head cap screw, and two hexagon socket head cap screws with small diameters are respectively fixed on two sides of the large hexagon socket head cap screw.

The utility model has the advantages that: the error of operating personnel because of the gimmick difference leads to is reduced, has improved the simplicity of placing the sample when sample testing, has guaranteed detection quality simultaneously, has improved efficiency greatly.

Fig. 2 is a side view of the clamping device.

In the figure: 1. rotating the handle; 2. a pin; 3. a fixed base; 4. a clamp fixing knob; 5. fixing the bolt; 6. a clamping block; 7. a hexagon socket head cap screw; 8. a hexagon socket head cap screw; 9. and (4) an inner hexagon bolt.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.

As shown in fig. 1, according to the embodiment of the present invention, a clamping apparatus includes a rotary handle 1, a pin 2 fixing base 3, a clamp fixing knob 4 and a clamping block 7: the fixture fixing knob 4 is fixed below the fixing base 3 through two

different fixing bolts

5 and 6; the clamping block 7 is fixed below the clamp fixing knob 4 through three inner hexagon bolts 8 and three inner hexagon bolts 9; one side of the clamping block 7 is inserted with the pin 2 and fixes the rotating handle 1.

In a specific embodiment of the present invention, the diameter of the fixing bolt 5 is larger than the diameter of the fixing bolt 6.

The diameter of the hexagon socket head cap screw 8 is larger than that of the hexagon socket head cap screw 9, and the number of the hexagon socket head cap screws 9 is two, and the two hexagon socket head cap screws 9 are respectively fixed on two sides of the hexagon socket head cap screw 8.

The utility model discloses a concrete embodiment, when putting into the sample vertical measuring position, when rotating the twist grip, the screw rod of handle promotes the clamp splice and moves left, fixes the pin on the clamp splice and also along with the clamp splice removes, after contacting with the sample, slightly exert oneself the twist grip, because the positioning action of two pins, the clamp splice will unable rotation for the sample is in the vertical position all the time, has guaranteed the accuracy that the sample detected.

For the convenience of understanding the above technical solutions of the present invention, the above technical solutions of the present invention are explained in detail through specific use modes below.

When specifically using, according to the utility model discloses a fixture device, including

twist grip

1, 2 fixed base 3 of pin, the fixed knob 4 of anchor clamps and clamp splice 7: the fixture fixing knob 4 is fixed below the fixing base 3 through two

different fixing bolts

After the electrolytic copper foil is produced, the strength and toughness of the electrolytic copper foil need to be detected so as to meet the production requirements of downstream industries. At the moment, a copper foil sample is cut into a strip shape of 15 multiplied by 100mm, the sample is clamped by fingers and placed in a measuring position to keep a vertical state, the upper part of the clamp is rotated to rotate the handle 1, the right side pushes the clamping block 7 to move leftwards, the pin 2 fixed on the clamping block also moves along with the clamping block, and when the sample is contacted with the clamping blocks on the left side and the right side, the rotating handle 1 is slightly rotated with force to fix the upper part of the sample; after the upper clamp is fixed, the copper foil sample is slightly stirred to naturally fall, the lower rotary handle of the clamp is rotated to operate the same as the upper clamp, so that the sample is always in a vertical position, and the instrument starts to be started after being clamped. In the process, kraft paper is pasted on the inner sides of the clamping blocks, so that the friction force between the copper foil and the clamping blocks is increased, and the copper foil and the clamping blocks cannot slide relatively when the copper foil is pulled by an instrument. And the fixed action of pin makes the clamp splice can not rotate along with the rotation of handle, can not lead to the sample straightness inconsistent that hangs down because of twisting the rotation handle elasticity degree difference when changing the sample, and it is simpler and easier to change the sample like this, has improved efficiency.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
