Description
Technical field
The utility model relates to tension test safety guard in a kind of physics and chemistry test, can in the process of tension test, better protect operating personnel and equipment itself, belongs to metal material physics and chemistry experimental technique field.
Background technology
Cupping machine in physics and chemistry test is the equipment for the mechanical property of various types of materials (being mainly tensile strength, yield strength, extensibility, end face shrinkage factor) is detected, and the sample holder method that at present conventional tensile test equipment adopts mainly comprises the clamping of folder face and screw thread clamping.In screw thread clamping, for the ease of the clamping of sample, normally two ends screw thread chuck is connected with sample, is then directly mounted to above the crossbeam of testing machine.After completing drawing process, testing crew takes out sample from fixture, then carries out the work such as dimensional measurement.Compare the clamping of folder face, the working method mechanical clearance of screw thread clamping is little, and sample and the difficult generation slip of clamping head, and test result is more more accurate than chuck method of clamping relatively, so range of application is more extensive.
But for a long time, utilizing screw thread clamping head to carry out in the process of metal material stretching test, we find because the direct carry of screw thread clamping head is below the crossbeam of testing machine, great vibrations in drawing process during sample fracture very likely ejects screw thread fixture and sample from fixture hanging groove, when very easily causing testing crew injured, the shock that fixture falls ground also can cause decline to a great extent the serviceable life of fixture itself, during simultaneously due to fracture, sample is also loaded in fixture, fixture can fall together with sample, the measurement of the distortion meeting that sample falls generation to the follow-up size of sample, as sample marking distance length, the measurement of sample deflation place diameter etc. has a negative impact.Therefore use this fixture all having certain defect aspect experimental safe, fixture durability and test accuracy.
Summary of the invention
The technical problems to be solved in the utility model is to improve security and the durability of screw thread stretching clamp.
In order to solve the problems of the technologies described above; the technical solution of the utility model has been to provide a kind of device that promotes tension test security performance; it is characterized in that; comprise the barrel-shaped screw thread fixture protective sleeve covering on the hanging groove parts of tensile test fixture; side and base plane at barrel-shaped screw thread fixture protective sleeve have the shape opening corresponding with hanging groove parts; on the outer circumference surface of barrel-shaped screw thread fixture protective sleeve, be provided with arc perforate, register pin is positioned at barrel-shaped screw thread fixture protective sleeve on hanging groove parts after inserting arc perforate.
Preferably, the front end of described register pin is the wedge shape of being convenient to insertion, and its rear end is provided with stop bit step.
The utility model increases certain device and overcomes the deficiency aspect its security and durability on the basis of continuing to use screw thread stretching clamp, make measuring accuracy and security, durability reach one well unified.
Accompanying drawing explanation
A kind of cut-open view that promotes the device of tension test security performance that Fig. 1 provides for the utility model;
Fig. 2 is the vertical view of barrel-shaped screw thread fixture protective sleeve;
Fig. 3 is the cut-open view of barrel-shaped screw thread fixture protective sleeve;
Fig. 4 is the vertical view of register pin;
Fig. 5 is the right view of register pin.
Embodiment
For the utility model is become apparent, the screw thread tensile test fixture of a cupping machine of hereby take is described further this device embodiment as example.
As shown in Figure 1, the utility model be take the hanging groove parts 1 of screw thread clamping head of cupping machine itself and as basis, has been customized a pair of barrel-shaped screw thread fixture protective sleeve 2, and a pair of register pin 5 is for positioning barrel-shaped screw thread fixture protective sleeve 2 in test.Barrel-shaped screw thread fixture protective sleeve 2 and register pin 5 adopt stainless steel or surface to adopt the ferrous material of the rust preventings such as blackout, japanning.Be convenient to reduce corrosion, increase the service life.The thickness of barrel-shaped screw thread fixture protective sleeve 2 and register pin 5 should be thinner, personnel's installation and removal easy to use.
As shown in Figures 2 and 3; barrel-shaped screw thread fixture protective sleeve 2 is the column barrel of an end opening; and in side and base plane, there is an opening 3 of a shape and hanging groove parts 1 structural correspondence; these axial and circumferential opening 3 sizes should be slightly larger than the size of hanging groove parts 1 after installing; make installation taking-up and 2 protective effects of barrel-shaped screw thread fixture protective sleeve own of fixture 6 obtain perfect combination, increase Practical Performance.Meanwhile, the chord length of opening 3 should be less than the top diameter of hanging groove parts 1, so just can play the effect of protection.On the outer circumference surface of barrel-shaped screw thread fixture protective sleeve 2, be provided with arc perforate 4.
As shown in Figures 4 and 5, the leading portion of register pin 5 has certain wedge shape, in the process of being convenient to test, insert and install, should guarantee that the root of register pin 5 is than the undersized of arc perforate 4 simultaneously, in process easy to use, insert and because of gravity reason, have the inclination of certain angle after inserting, make difficult drop-off in its vibration when fracture.There is stop bit step at the rear portion of register pin 5, can be fixed register pin 5 positions own, guarantees to be in place and can play a protective role.
Get back to Fig. 1; upper and lower two barrel-shaped screw thread fixture protective sleeves 2 cover from top by hanging groove parts 1 respectively; should make hanging groove opening overlap with the opening 3 of protective sleeve; be convenient to by fixture hang into; after fixture 6 is hung; it is axle Rotate 180 ° that two barrel-shaped screw thread fixture protective sleeves 2 all be take to himself axis, so far, has realized the protective effect to fixture 6 and sample.Next register pin 5 is inserted in the arc perforate 4 of protective sleeves, register pin 5 moves as the axial and circumferential that object of reference carries out with regard to stoping barrel-shaped screw thread fixture protective sleeve 2 to take stretching axis like this, thereby guarantees safety.The gap of the barrel-shaped screw thread fixture protective sleeve 2 of made after installing and between fixture 6 be in 1-2mm left and right, avoids that gap is too small to be difficult to install or excesssive gap does not have protective effect or increases the shock dynamics while vibrating.Should guarantee that barrel-shaped screw thread fixture protective sleeve 2 installs the size that effective length afterwards is slightly longer than hanging groove parts 1, the protection while guaranteeing to vibrate is effective.
After tension test completes, take off register pin, by 180 ° of protective sleeve opposite spins, can take off tensile test fixture and carry out sample unloading and clamping again.
