Abstract
The invention discloses a clamp used for measuring the tensile strengths of bolts. The clamp comprises an upper clamp and a lower clamp, three step holes having different apertures are arranged in the center of the bottom of the upper clamp, one side of each of the three step holes has an opening, the opening side of each of the step holes and one side of the upper clamp are provided with through slots for the go-through the heads of bolts for measurement, the positions of the lower clamp corresponding to each of the step holes are provided with screwed holes having corresponding apertures, and the top of the upper clamp and the bottom of the lower jig are respectively provided with three joints. By adopting the above structure, the bolts for measurement go through the through slots in the upper clamp and are placed in the step holes when the bolts for measurement are replaced to measure each time, and the bolts for measurement are removed from the step holes through the through slots after the measurement. The clamp has the advantages of no need of frequent dismounting and mounting, reduction of the labor intensity and use convenience; and the three step holes having different apertures and the screwed holes allow one clamp to be adapted to the measurement of three bolts for measurement having different diameters, so cost investment of a user is reduced, and the storage is convenient.
Description
Technical field
The present invention relates to a kind of bolt verifying attachment, particularly a kind of for measuring the fixture of bolt tensile strength.
Background technology
On February 13rd, 2013, disclosed No. 201220343637.7 Chinese utility model patent, comprised fixture, lower clamp, and upper clamp base is provided with through hole, and bolt to be measured one end is passed from this through hole, and the other end matches with the threaded hole of lower clamp.This patent has solved puller system clamping plate serious wear and has stepped up unstable problem.But the prior art is in each replacing bolt test to be measured, even specification of the same race bolt to be measured is changed, also need upper fixture to disassemble from the clamping plate of puller system, carry out the installation of bolt to be measured, after installation, upper fixture and puller system clamping plate are fixed.When larger for test batch, hand labor intensity is large, and it is very inconvenient to use; In addition, fixture can only carry out an a kind of test of bolt to be measured of specification, if need to test the bolt to be measured of three kinds of different-diameter specifications, needs to make or buy the fixture of 3 cover different sizes, increased user's use cost, nor convenient storage.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned the deficiencies in the prior art, and provide a kind of hand labor intensity little, easy to use and can compatible many specifications bolt to be measured for measuring the fixture of bolt tensile strength.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of for measuring the fixture of bolt tensile strength, comprise fixture and lower clamp, described upper clamp base central authorities are at least provided with the stepped hole of a side with opening, one side of the open side of each stepped hole and upper fixture is provided with the through slot that can pass through for bolt head to be measured, lower clamp is respectively arranged with corresponding position, each stepped hole position the threaded hole coordinating with bolt thread to be measured, and upper fixture top and lower clamp bottom are provided with at least one connector.
Described upper clamp base central authorities are disposed with the stepped hole of three different pore sizes, and described lower clamp is disposed with three threaded holes identical with corresponding stepped hole aperture.
Described upper fixture and lower clamp are rectangular parallelepiped.
The present invention adopts after said structure, while changing bolt test to be measured, only need, by bolt to be measured by the through slot in upper fixture, be positioned in stepped hole at every turn, after having tested, then bolt to be measured is ejected through through slot and is taken out from stepped hole.Do not need fixture in demolition, installation back and forth, reduced hand labor intensity, easy to use; In addition, stepped hole, threaded hole are provided with three, and aperture is variant, and a sleeve clamp can adapt to the bolt to be measured of 3 kinds of different-diameters to be tested, and the cost that has reduced user drops into and stores conveniently.
Accompanying drawing explanation
Fig. 1 is that the present invention is a kind of for measuring the structural representation of fixture of bolt tensile strength.
Wherein have: 1. go up fixture; 2. lower clamp; 3. stepped hole; 4. bolt to be measured; 5. threaded hole; 6. connector; 7. through slot.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further detailed explanation with concrete preferred embodiments.
As shown in Figure 1, a kind of for measuring the fixture of bolt tensile strength, comprise fixture 1 and lower clamp 2, described upper fixture 1 bottom center is provided with a side of three different pore sizes with the stepped hole 3 of opening, one side of the open side of each stepped hole 3 and upper fixture 1 is provided with the through slot 7 that can pass through for bolt 4 heads to be measured, lower clamp 2 and each stepped hole 3 corresponding positions, position are respectively arranged with three corresponding apertures and threaded holes 5 bolt 4 threaded engagement to be measured, and upper fixture 4 tops and lower clamp 2 bottoms are provided with three connectors 6.Each stepped hole 3, threaded hole 5 and upper fixture 1 top corresponding with its aperture keep coaxial setting with the connector 6 of lower clamp 2 bottoms.
Described upper fixture 1 is rectangular parallelepiped with lower clamp 2.Also can be cube or cylindrical shape etc.
When each replacing bolt 4 to be measured is tested, according to the diameter of screw size of bolt 4 to be measured, select corresponding stepped hole 3 and threaded hole 5, connector 6 corresponding on upper fixture 1 and lower clamp 2 is connected on the clamping plate of puller system, makes stepped hole 3, threaded hole 5 keep coaxial with the connector 6 of upper fixture 1 top, lower clamp 2 bottoms; After by bolt to be measured 4 by the through slot 7 in upper fixture 1, be positioned in stepped hole 3, after having tested, then bolt 4 to be measured is ejected through through slot 7 and is taken out from stepped hole 3.If the bolt to be measured 4 of same diameter specification does not need fixture in demolition, installation back and forth, reduced hand labor intensity, easy to use; In addition, stepped hole 3, threaded hole 5 are provided with three, and aperture is variant, and a sleeve clamp can adapt to the bolt to be measured 4 of 3 kinds of different-diameters to be tested, and the cost that has reduced user drops into and stores conveniently.
