The verification of tight machine and caliberating device, mainly use horizontal small car formula calibration equipment, the device mainly by return pulley, steel structure frame,
Handrail, simulation shaft end and the combination of left and right supporting leg are constituted, and are designed with motor car wheel the height such as central axis since it is used, therefore can be with
Meet live multiple-shaft tightening machine and verifies requirement for height.Multiple-shaft tightening machine is needed in verification and calibration through carrier gas multiple-shaft tightening
The simulation shaft end being arranged on dynamic torque sensor, extension bar and sleeve and horizontal small car formula calibration equipment in machine tightening axle connects
It connects；In checking procedure, due to the dynamic torque sensor of connection, lengthening among multiple-shaft tightening machine and horizontal small car formula calibration equipment
Bar and sleeve link are excessive, ground out-of-flatness in addition, and scene is difficult to ensure multiple-shaft tightening machine axis and horizontal calibration equipment
Axis it is consistent and be overlapped, therefore checking precision is relatively low, is not able to satisfy requirement.
Utility model content
The purpose of this utility model is: to solve the deficiencies in the prior art, providing a kind of mark for tightening calibration equipment
Determine tooling.
The technical solution of the utility model is: a kind of calibration tooling for tightening calibration equipment, it include: calibration main body,
Set lever and positioning screw；
Demarcating main body includes: connecting shaft, and be mounted on one end of the connecting shaft tightens axle sleeve, is mounted on connecting shaft other end upper end
The boss in face；Tightening axle sleeve is symmetrical structure, which is provided at least two through-holes；
Set lever is arranged in the through hole for tightening axle sleeve, and the quantity of quantity and through-hole matches, for passing through through-hole
Tightening axle locked；
Positioning screw is arranged on boss, for locking to the dynamic torque sensor in tightening axle.
Application method are as follows:
Upper through-hole is covered by tightening axle, calibration tooling is socketed in the tightening axle for tightening axle box, at least two are tightened
Axis is passed through from the through-hole on tightening axle set, and will be demarcated main body by set lever and tightened shaft locking, prevents workpiece from verifying
It loosens in the process；Dynamic torque sensor is installed in tightening axle, using the positioning screw being arranged on boss in tightening axle
Dynamic torque sensor locked, prevent dynamic torque sensor from falling, later to multiple-shaft tightening machine and horizontal small car formula
Calibration equipment is attached, and carries out calibration and verifying work.
Further, for convenience of the installation and removal for demarcating tooling, above axle sleeve is being tightened equipped with handle.
Specific in above scheme: the lower part of tight handle is that helicitic texture, set lever and through-hole side wall are connected by screw thread
It connects.
Positioning screw is connected through a screw thread with boss.
Handle and tightening is connected between axle sleeve by M6 hexagon socket cap head screw, and is loosened with spring washer.
The utility model has the advantages that can guarantee the axis and horizontal small car formula calibration equipment of multiple-shaft tightening machine using the utility model
Axis is consistent and is overlapped, and checking precision is higher, meets live requirement.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of horizontal small car formula calibration equipment described in background technology；
Fig. 2 is the structural schematic diagram of the utility model；
Fig. 3 is the structural schematic diagram that main body is demarcated in the utility model；
Wherein: 1- demarcates that main body, 11- connecting shaft, that 12- tightens axle sleeve, 13- boss, 2- set lever, 3- handle, 4- is fixed
Position screw.
