Abstract
The invention belongs to torque measurement interconnection technique, and in particular to a kind of split type switching square set.It includes upper left (1), lower right-most portion (2), and upper left 1 and lower right-most portion 2 can obtain the switching square hole of corresponding size after correctly being docked along dotted line.It vertically cuts open into upper left and lower right-most portion using integrally two points of structure design after shaping is integrally machined, then along the interior square hole diagonal of switching square set.A kind of split type switching square set that highly short, size is adaptable, small, anti-lost on the influence of torque measurement result of transferring is provided.
Description
In technical field：
The invention belongs to torque measurement interconnection technique, and in particular to a kind of split type switching square set.
Background technology：
During using detecting device for determining torque of spanner calibrating torque spanner, usually because square falcon at both connecting interfaces and
Square hole size is inconsistent and needs to increase switching square set.And the installation concentricity of the setting height(from bottom) after transferring, square falcon and square hole, with
And square falcon, the fit precision of square hole, it can all influence the accuracy of torque spanner verification result.And square falcon, the fit precision of square hole
Excessive the problem of not only increasing installation difficulty but also other torque wrenches of same size can be caused not install.In addition, switching
Square set small volume, does not pay attention to slightly to be easy to lose as torque spanner is pulled away together after the completion of calibrating.
Switching square set on the market is constrained by its structure, highly increases more, junction size after generally existing switching
Bad adaptability, it is easy to be lost the problems such as.
The content of the invention：
The purpose of the present invention is：A kind of switching of offer is highly short, size is adaptable, it is small that torque measurement result is influenced,
Anti-lost split type switching square set.
The technical scheme is that：A kind of split type switching square set, it includes upper left 1, lower right-most portion 2, upper left
Part 1 and lower right-most portion 2 can obtain the switching square hole of corresponding size after correctly being docked along dotted line.It uses the structure of two points of one
Design, upper left 1 and lower right-most portion 2 are vertically cutd open into after shaping is integrally machined, then along the interior square hole diagonal of switching square set.
The solution have the advantages that：Basic function of the split type switching square set of the present invention except retaining tradition switching square set
Outside, following improvement has also been carried out：1) mediator Tao Shang foreign sides falcon and interior square hole highly essentially coincide, and greatly reduce switching band
The setting height(from bottom) increase problem come；2) using integrally two points of structure design, in force, split type switching square set can play one
Fixed flexible connection and the effect of automatic aligning, it is ensured that concentricity is installed well, is effectively reduced because square falcon and square hole
Fit precision problem cause installation it is not coaxial so that the problem of influencing torque measurement result accuracy；Avoid switching at the same time
Square set is not easy to remove, and the problem of being pulled away with utensil, has certain loss prevention function.
Brief description of the drawings：
Fig. 1 is the front view of the split type switching square set of the present invention；
Fig. 2 is the top view of the split type switching square set of the present invention,
Wherein, 1 it is upper left, 2 is lower right-most portion.
Embodiment
The present invention will be further described with example below in conjunction with the accompanying drawings：
Please refer to Fig.1 and Fig. 2, the split type switching square set of the present invention include upper left 1, lower right-most portion 2, upper left 1
It can obtain the switching square hole of corresponding size after correctly being docked along dotted line with lower right-most portion 2.The switching square set of the present invention is using one
Two points of structure design, 1 He of upper left is vertically cutd open into after shaping is integrally machined, then along the interior square hole diagonal of switching square set
Lower right-most portion 2.Split type switching square set can not only play the purpose for changing junction square hole size size on demand, Er Qieke
Take and caused square hole and square falcon to coordinate difficult problem since machining tolerance is inconsistent, enhanced the applicability of switching square set；Separately
During external force, split type switching square set can play the role of certain flexible connection and automatic aligning, it is ensured that peace well
Concentricity is filled, is effectively reduced because the fit precision problem of square falcon and square hole causes installation not coaxial, so as to influence torque measuring
The problem of measuring result accuracy；The problem of being not easy to remove, can be pulled away with utensil this configuration avoids switching square set at the same time,
With certain loss prevention function.
When using split type switching square set, first by the upper left 1 of split type switching square set and lower right-most portion 2 along figure
Dotted line position is bonded in 1, then by the square hole of the foreign side's falcon insertion detecting device for determining torque of spanner formed after fitting, will finally be turned round again
In the interior square hole that the split type switching square set of square falcon head insertion of square spanner is formed, examined so as to complete torque spanner and torque spanner
Determine the coaxially connected work of instrument.
Claims (2)
- The square set 1. a kind of torque measurement is transferred, the measurement object is torque spanner, it is characterized in that：The square set is tetragonous Column, inside are provided with square hole, and square set is inserted into detecting device for determining torque of spanner, in torque spanner insertion square set square hole；It is two parts that the square set is longitudinally split along square diagonal.
- 2. a kind of torque measurement switching square set according to claim 1, it is characterized in that：Set on the end face of square set limited Position boss.
