Embodiment

The embodiment of the utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning Same or similar element is represented to same or similar label eventually or there is same or like element.Below by ginseng The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and it is not intended that to the utility model Limitation.

The survey that part is embedded to nut and pull torsion-testing below with reference to Fig. 1 descriptions according to the utility model embodiment Trial assembly puts 100.

Pull the test device 100 of torsion-testing according to the part 200 that is embedded to nut of the utility model embodiment and wrap Include：First support base 110, the second support base 120, bolt 130 and torque wrench 140, the first support base 110, which has, to be used to pacify Loading nut is embedded the mounting portion 111 of part 200, and the second support base 120 is located at the top of the first support base 110, and the second support base 120 has There is the avoiding space a that for nut is embedded part 200 abjection opposite with mounting portion 111, the second support base 120 has rotationally pivot Transfer part 1213, bolt 130 sequentially pass through avoiding space a and mounting portion 111 and are only against on pivot part 1213, and bolt 130 is used for 200 screw-driven of part is embedded with nut, torque wrench 140 is connected with bolt 130 to drive bolt 130 to rotate, and shows moment of torsion Value.

It should be noted that pulling moment of torsion refers to that nut 210 is embedded moment of torsion when deviating from part 200 from nut, that is, The flashy critical torque value that nut 210 is pulled out.

According to the test device 100 that part 200 is embedded to nut and pull torsion-testing of the utility model embodiment, lead to Cross the first support base 110 and fix nut and be embedded part 200, and avoiding space a is limited to facilitate spiral shell by the second support base 120 Mother 210 deviates from, and the second support base 120 has pivot part 1213, and then during the test, pivot part 1213 can be with spiral shell Bolt 130 rotates, and bolt 130 does not contact directly with nut 210, and the second support base 120 is also spaced apart with nut 210, so that In 140 screwing operations of torque wrench, nut 210 can move abjection upwards, and nut is embedded part 200, bolt 130 can freely turn It is dynamic, to reduce influence of the frictional force to test result.

In this way, by rotation torque spanner 140 so that nut 210 deviate from nut be embedded 200 measuring method of part, belong to direct Mensuration, without carrying out numerical value conversion, by frictional influence is small, measurement result is accurate, precision is high, easy to operate.

The test device 100 that part 200 is embedded to nut and pull torsion-testing referring to Fig. 1 to the utility model Test method be described in detail：

Nut is embedded part 200 by the first support base 110 to fix, the second support base 120 is arranged on the first support base 110 top and limit avoiding space a, one end of bolt 130 through avoiding space a to be spirally connected with nut 210, bolt 130 other end is connected with torque wrench 140, and then by driving torque spanner 140 and drives bolt 130 to rotate, bolt 130 Rotation makes 210 prolapse upwards nut of nut be embedded part 200, is rotated further torque wrench 140 until 210 completely out nut of nut It is embedded part 200 and records the registration of torque wrench 140 at this time.

In this way, when 210 completely out nut of nut is embedded part 200, the registration shown by torque wrench 140 is exactly tested What the nut of examination was embedded part 200 pulls moment of torsion.

As shown in Figure 1, the second support base 120 includes：Rolling bearing 121 and supporting pad 122, rolling bearing 121 include solid Determine portion 1211, rolling element 1212 and pivot part 1213, connected between pivot part 1213 and fixed part 1211 by rolling element 1212 Connect and be rotatably assorted with being formed, supporting pad 122 is between pivot part 1213 and bolt 130, supporting pad 122 and rolling bearing 121 Avoiding space a is limited jointly.

Specifically, supporting pad 122 is installed on the top of the first support base 110, and rolling bearing 121 with rolling bearing 121 200 phase of part is at least partly embedded with nut only to support.In this way, the abjection space for not only limiting nut 210 in the axial direction (avoids Space a), to facilitate nut 210 to deviate from, also nut is embedded in the axial direction part 200 carry out it is spacing, to prevent nut to be embedded part 200 opposite first support bases 110 move upwards.

In addition, rolling bearing 121 is arranged on supporting pad 122 and nut is embedded between part 200, and rolling bearing 121 is opposite Nut is embedded part 200 and can rotate, and then by setting rolling bearing 121, makes the survey caused by frictional force in test process Error smaller is measured, to improve the measurement accuracy of test device 100.

In the specific embodiment shown in Fig. 1, pivot part 1213 and fixed part 1211 along rolling bearing 121 it is axial according to It is secondary to be distributed and be spaced apart.Thus, by setting the pivot part 1213 and fixed part 1211 that are sequentially distributed and are spaced apart, rolling is not only made Dynamic bearing 121 is more uniformly stressed, so that the structure of the second support base 120 is more stablized, also makes rolling bearing 121 and support The connection of pad 122 is even closer.

Certainly, in the utility model rolling bearing 121 structure not limited to this, pivot part 1213 may be formed as rolling The inner ring of bearing 121, fixed part 1211 are formed as the outer ring of rolling bearing 121, and supporting pad 122 is fixedly connected with pivot part 1213 And it is spaced apart with fixed part 1211, one end of the first support base of direction 110 of pivot part 1213 retraction fixed part in the axial direction In 1211.

Thus, being retracted into fixed part 1211 by one end of the first support base of direction 110 of pivot part 1213, so that Rolling bearing 121 and nut are embedded the friction smaller between part 200, so that the measurement result of test device 100 is more accurate.

Alternatively, supporting pad 122 is metal gasket.Specifically, the upper end of supporting pad 122 is connected with bolt 130, lower end It is connected with rolling bearing 121, and during the test, supporting pad 122 needs to support bolt 130, to prevent 130 direction of bolt First support base 110 moves.Thus, by the setting of supporting pad 122, make test device 100 that there is the job stability of higher.

In the specific embodiment shown in Fig. 1, the projecting shaft 141 of torque wrench 140 is connected with bolt 130 by sleeve 150 Connect, one end of sleeve 150 is mating with the projecting shaft 141 of torque wrench 140 and the other end and bolt 130 are mating.

In this way, by mating bolt 130 and sleeve 150, torque wrench 140 and sleeve 150, not only facilitate test The dismounting of device 100, and make the operation of test device 100 during the test simpler.

Further, bolt 130 has non-circular bolt head 131, and sleeve 150 has non-circular first spliced eye 151 and second spliced eye 152, bolt head 131 is only against on the first support base 110 and is adapted with the first spliced eye 151, stretch out Axis 141 is non-circular and is adapted with the second spliced eye 152.

Thus, it is possible to by replacing sleeve 150 so that sleeve 150 is adapted from different bolts 130, and then fills test Putting 100 has the scope of application of bigger.

In addition, it is connected by non-circular first spliced eye 151 with non-circular bolt head 131, non-circular second inserts Connect hole 152 and non-circular output axis connection, make bolt head 131 and sleeve 150, sleeve 150 and torque wrench 140 connection more Stablize, reduce circumferential play between the two, transmission is more steady.

Some embodiments according to the present utility model, the first support base 110 are multi-jaw chuck, and mounting portion 111 is formed at more The inner of each claw of dog chuck, each claw of multi-jaw chuck can be synchronized with the movement with the size of adjust installation portion 111.

In this way, by setting multi-jaw chuck, not only make nut be embedded fixation of the part 200 on mounting portion 111 it is more firm, It is firm, also adjust the size of mounting portion 111, and then test device 100 is applicable in by the mounting portion 111 of adjustable dimension Part 200 is embedded in the nut of more different sizes, and then further increases the versatility of test device 100.
