Abstract
The utility model relates to a pincers mouth protective cover for a pull tester, belonging to an accessory for force measuring instruments. The pincers mouth protective cover for a pull tester is used for protect a pincers mouth of a pull tester. The pincers mouth protective cover for a pull tester is characterized in that the pincers mouth protective cover for a pull tester comprises a front fixing section (5), a rear fixing section (10) and a middle extending section (11). The pincers mouth protective cover for a pull tester has the functions of covering all gaps existing at a slid rail of a pincers mouth, preventing rust or other foreign materials from falling in the gaps and effectively protecting the pincers mouth, and therefore, the pincers mouth protective cover for a pull tester prolongs the service life of the pincers mouth and reduces a trouble that the pincer mouth is frequently replaced in working. The utility model has the advantages of simple structure, easy fabrication, easy installation, no destruction on an original machine body, no influence on the accuracy of testing data, etc.
Description
The utility model discloses a kind of tension tester jaw protective cover, belong to the auxiliary equipment of dynamometry instrument, be used for the jaw of tension tester is protected.
The tension tester that generally adopts in the present engineering test chamber, the structure of its associated jaw portion basically as shown in Figure 1, jaw [4] and jaw seat [1] motion mutually, both sliding rail places certainly exist slit [3], in process of the test, the rust on the test specimen or other chips fall into wherein easily, thereby have destroyed lubricating on the sliding rail, reduced the serviceable life of jaw greatly, cause often changing in the work.In addition; because the sliding rail between jaw and jaw seat is a slipping plane is again stress surface; if the centre falls into some granule or chip; this face will go to pot along with the increase of pressure or be out of shape; thereby reduced the stability of power in the test, have influence on precision of test result and notarization property to a great extent.
The purpose of this utility model provide a kind of can be to the associated jaw portion of tension tester, especially the cover of protective action is played at the sliding rail position, thereby avoids the generation of above-mentioned phenomenon.
Basic design of the present utility model is that described protective cover is made of three parts: two ends are forward and backward canned paragraph, and the centre is the extension.Forward and backward canned paragraph is made by hard material, is installed in the top of jaw and jaw seat respectively, plays the fixedly effect of whole protective roof.The shape of forward and backward canned paragraph, size match with the profile of jaw and jaw seat respectively.Middle extending segment is made with flexible material, can moving up and down and freely stretch with jaw.
Of the present utility modelly be characterised in that canned paragraph [5] before described tension tester jaw protective cover is by the rigidity that is installed on by tightening screw [6] and installation sheet [7] above the jaw [4] and be installed on canned paragraph [10] and flexible and extendable section [11] between the two formation after the rigidity above the jaw seat [1] that three sections are connected as a single entity by installation sheet [8] and tightening screw [9].
Above-mentioned preceding canned paragraph [5] and back canned paragraph [10] their shape are consistent with the profile of above-mentioned jaw [4] and jaw seat [1] respectively.
Above-mentioned installation sheet [8] is fixed on the jaw seat [1] by clamp nut [2].
The utility model has the advantages that and the slit at jaw slide rail place all can be covered in, avoided iron rust or other foreign matters to fall into wherein, jaw has been played effective protective effect, prolonged its serviceable life greatly, reduced the trouble of often changing in the work; And having simple in structurely, fabrication and installation are convenient, do not destroy former body, do not influence the accuracy of test figure.
The accompanying drawing part has been described a specific embodiment of the present utility model by the contrast of Fig. 1 and Fig. 2:
Fig. 1 is the testing machine associated jaw portion sectional perspective synoptic diagram that this protective cover is not installed;
Fig. 2 is the testing machine associated jaw portion sectional perspective synoptic diagram behind this protective cover of installation.
Can know from Fig. 1 and to see that the sliding rail place forms slit 3 between jaw seat 1 and the jaw 4.And as shown in Figure 2, this slit is covered by protective cover.The preceding canned paragraph 5 of protective cover by a tightening screw 6 and installation sheet 7 be attached to tightly jaw 4 above.The back canned paragraph 10 of protective cover by installation sheet 8 and tightening screw 9 be close to jaw seat 1 above, fixedly the realizing of installation sheet 8 by clamp nut 2.The centre of protective cover is extension 11, and the most handy rubber, plastics etc. have better flexible flexible material to be made, and freely stretches with the upper and lower displacement of jaw to guarantee it.
Claims (3)
1, a kind of tension tester jaw protective cover, it is characterized in that canned paragraph [5] before this protective cover is by the rigidity that is installed on by tightening screw [6] and installation sheet [7] above the jaw [4] and be installed on canned paragraph [10] and flexible and extendable section [11] between the two formation after the rigidity above the jaw seat [1] by installation sheet [8] and tightening screw [9], three sections are connected as a single entity.
2, tension tester jaw protective cover according to claim 1 is characterized in that above-mentioned preceding canned paragraph [5] and back canned paragraph [10] their shape are consistent with the profile of above-mentioned jaw [4] and jaw seat [1] respectively.
