Description
Technical field
The present invention relates to clamp device, be specifically related to a kind of knockdown material clamp.
Background technology
The compression universal testing machine can carry out mechanical property testing and analysis and research to materials such as metal, nonmetal, compound substances, is widely used in the every field such as space flight and aviation, agricultural production, petrochemical complex, machine-building.The compression universal testing machine need to use supporting anchor clamps when material is compressed, and when namely material being carried out mechanical property testing and analysis and research, needs anchor clamps first material to be fixedly clamped, and then compresses universal testing machine and material is tested again.
At present, the anchor clamps for the compression universal testing machine have the dull and stereotyped compression clamp of disk, two kinds of universal fixturings of 90 ° of V-block anchor clamps.In the reality test, require tested material to have different shapes, namely tested material has difform to be clamped, and such as plane, arc surface and gore etc., and the size of these arc surfaces or gore etc. is different.Because the angle of the dull and stereotyped compression clamp of existing disk and 90 ° of V-block anchor clamps all can not be adjusted, so these two kinds of anchor clamps can not clamp most of materials.If need to have difform material and detect above-mentioned, then need again to make the special fixtures corresponding with the material profile, thereby cause long, high in cost of production problem of test duration.Because each anchor clamps all are to design for different materials, thereby cause the versatility of anchor clamps poor.
Summary of the invention
The deficiency that the present invention exists in order to overcome above prior art provides a kind of simple and reasonable for structure, the knockdown material clamp that versatility is high.
Purpose of the present invention realizes by following technical scheme: this knockdown material clamp, described grip device comprises coupling shaft, back up pad, the first clamping plate and the second clamping plate, described back up pad is installed on an end of coupling shaft, the two ends of described back up pad are respectively equipped with the first cushion block and the second cushion block, one end of described the first clamping plate is connected in the first cushion block, the other end and the middle part that is articulated in back up pad; One end of described the second clamping plate is connected in the second cushion block, and the other end is articulated in the middle part of back up pad, and the other end of the other end of described the first clamping plate and the second clamping plate is hinged simultaneously.
The height of described the first cushion block equates with the height of the second cushion block.The height of the height of the first cushion block and the second cushion block can equate, also can be unequal.When the height of the first cushion block equates with the height of the second cushion block, can very stable clamping has the material of arc surface or gore; And when the height of the height of the first cushion block and the second cushion block was unequal, this also can clamp material, and the material for the different gore of the length with two adjacent sides clamps especially.
The height of described the first cushion block is 22mm～42mm, and the height of described the second cushion block is 22mm～42mm.The height of the first cushion block and the second cushion block is selected according to actual conditions, such as the shape according to material.Change height by the first cushion block and the second cushion block of selecting differing heights, thereby regulate the angle between the first clamping plate and the second clamping plate.
Described knockdown material clamp also comprises at least 1 the first regulating block and at least 1 the second regulating block, and described the first regulating block is installed on upper end or the lower end of the first cushion block, and described the second regulating block is installed on upper end or the lower end of the second cushion block.Carry out height by the quantity that increases the first regulating block and the second regulating block and regulate, this can realize the angle between quick adjustment the first clamping plate and the second clamping plate.
Described knockdown material clamp also comprises bolt, and the two ends of described back up pad are provided with slotted eye, and described the first cushion block and the second cushion block are installed on respectively on the slotted eye by bolt; Described slotted eye takes the shape of the letter U or kidney-shaped.Slotted eye the distance that can regulate between the first cushion block and the second cushion block is set, thereby the angle between quick adjustment the first clamping plate and the second clamping plate is simple to operation.
Described knockdown material clamp also comprises 2 web joints and 2 hinges, and wherein an end of a web joint is connected with the first clamping plate by one of them hinge, and an end of another web joint is connected with the second clamping plate by another hinge.
The quantity of described knockdown material clamp is 1 or 2.Use when this knockdown material clamp can independent 1, also can be used in combination by 2, thereby applicable to how different materials is clamped.
The front of described the first clamping plate and the second clamping plate is equipped with executes carrier, the described size of carrier and the size coupling of the first clamping plate executed, the described size of carrier and the size coupling of the second clamping plate executed.When tested material has viscoelasticity, for the first clamping plate of avoiding metal material directly contact material with the second clamping plate, thereby prevent that material is damaged.When above-mentioned material is tested, execute the error that carrier can reduce test result.This is because the first clamping plate of metal material when directly contacting with material with the second clamping plate, cause easily the mechanical property of material inside and institutional framework to change, thereby affect test result.Execute simultaneously the effect that carrier can also play to the first clamping plate and the second clamping plate protection.
The described material of executing carrier is any one in leather, metal, plastics and the cork.Execute the material of carrier and select different material manufacturings according to material.Except above-mentioned material, can also be rubber.
As a kind of preferred, the middle part of described back up pad is provided with hinged seat, and the other end of the other end of described the first clamping plate and the second clamping plate all is articulated in hinged seat.
Principle of work of the present invention: this knockdown material clamp is installed on the compression universal testing machine by coupling shaft; Before material is tested, the first cushion block and the second cushion block by changing differing heights or utilize the first regulating block and the second regulating block carries out height adjusting, thereby regulate the angular dimension between the first clamping plate and the second clamping plate, make angle between the first clamping plate and the second clamping plate and clamped adaptation of material, then this knockdown material clamp can more stably clamp material and highly versatile.
The present invention has following advantage with respect to prior art:
1, the angle between the first clamping plate and the second clamping plate is adjustable in this knockdown material clamp, thereby can clamp according to the face to be clamped of different material, so highly versatile needn't be made corresponding anchor clamps according to different materials, this greatly reduces cost, has also reduced the test duration simultaneously.
2, this knockdown material clamp is executed carrier by arranging in the front of the first clamping plate and the second clamping plate, thus the mechanical property of accurate response tested material more.
3, this knockdown material clamp utilizes the first cushion block and the second cushion block to change height, thereby can easily change angle between the first clamping plate and the second clamping plate, has the characteristics such as easy to operate, simple in structure and easy accessibility.
