Abstract
The utility model discloses bent axle is cranked arm, and poor testing fixture dimple is strong to be possessed comprises internal thread sleeve pipe (1), left jumper bar (2a), right jumper bar (2b), controls jumper bar (2a, 2b) and comprises threaded rod (21), six prisms (22), post pole (23), closed angle drift (24), controls threaded rod (21) of jumper bar (2a, 2b) and is connected with the both ends screw cooperation of controlling of internal thread sleeve pipe (1) respectively. Its simple structure makes portably, puts into two crank arm interfacials, and jumper bar (2a, 2b) is confirmed on two crank arm faces about rotatory makes ejecting dimple on the nest centre spot, operates convenient to use.
Description
Technical field
The utility model relates to when detecting to the difference of cranking arm of two crank arm of bent axle, in order to by cubing location and installation
Between cranking arm two, that dimple is driven on the face of cranking arm rushes tool.
Background technology
When difference of bent axle cranking arm is detected, it is to use dial gauge for measuring of crank spread（Fixed pole is respectively arranged at two ends with the left and right of dial gauge and press
Bar is constituted）It is placed between two crank arms, then rotates bent axle, observation dial gauge for measuring of crank spread indicates change in value to be detected.
When difference of bent axle cranking arm is detected, dial gauge for measuring of crank spread is placed on trunnion and plane determined by crank-pin axle journals axis,
And with crank pin linear distance be setting.
In order to lay dial gauge for measuring of crank spread between two crank arms, it is necessary to get dimple respectively on two crank arm faces, then
Dial gauge for measuring of crank spread is pacified on the dimple that bar is respectively inserted on two crank arm faces by pressing for the fixed pole and right-hand member of dial gauge for measuring of crank spread left end
It is mounted between two crank arm faces.
Prior art in order to get dimple on two crank arm faces, using the jumper bar that head wedge angle is 60 degree, hand-held punching
Bar taps jumper bar rear end with hammer, and the point position determined on crank arm face carries out rushing nest,
Above-mentioned prior art is this to rush nest mode, and as two crank arm interplanar distances are less, jumper bar oblique can only be stretched into one
The crank arm face of side carries out rushing nest operation, and anthropic factor affects error larger, inconvenient operation, and it is poor to rush nest accuracy, rushes nest matter
Amount is poor, and it is bad that nest conformability is rushed in the insertion of two side poles of dial gauge for measuring of crank spread, affects detection, and detection is accurately low.
Utility model content
The purpose of this utility model is to provide a kind of simple structure, and manufacture is easy, and difference of bent axle easy to use cranking arm is detected
Cubing dimple punching tool.
This utility model bent axle is cranked arm poor detection tool dimple punching tool, by internally threaded sleeve 1, left jumper bar 2a, right jumper bar
2b is constituted, and left and right jumper bar 2a, 2b is made up of threaded rod 21, six prisms 22, mast 23, wedge angle drift 24, left and right jumper bar 2a, 2b's
Threaded rod 21 is connected with the left and right two ends screw of internally threaded sleeve 1 respectively.
This utility model simple structure, manufacture are easy, easy to use.
This utility model using when be put between two crank arm faces, left and right jumper bar 2a, 2b is by the point of left and right jumper bar 2a, 2b for rotation
Angle drift 24 is respectively aligned to withstand on beating on nest centre spot of determining on two crank arm faces, then with two spanners respectively with left and right
Six prisms 22 on jumper bar 2a, 2b coordinate, and rotate left and right jumper bar 2a, 2b, make left and right jumper bar 2a, 2b double side acting pressure to the left and right
Ejection dimple.
Then pressing the fixed pole and right-hand member of dial gauge for measuring of crank spread left end on the dimple that bar is respectively inserted on two crank arm faces
Dial gauge for measuring of crank spread is arranged between two crank arm faces, dial gauge for measuring of crank spread is imitated and is started the detection crank-pin to for 0, rotating bent axle afterwards
Crank arm difference.

Fig. 3 is installment state schematic diagram when dial gauge for measuring of crank spread is detected to difference of cranking arm.
Specific embodiment
This utility model bent axle is cranked arm poor detection tool dimple punching tool, by internally threaded sleeve 1, left jumper bar 2a, right jumper bar
2b is constituted, and left and right jumper bar 2a, 2b is made up of threaded rod 21, six prisms 22, mast 23, wedge angle drift 24, left and right jumper bar 2a, 2b's
Threaded rod 21 is connected with the left and right two ends screw of internally threaded sleeve 1 respectively.
Claims (1)
