Abstract
The utility model relates to a locking mechanism of a precision indexing device, which is equipment for raising the precision of measurement. When the existing locking device of the precision indexing device performs the operation of measurement, locking variation is large, the variation of indicated value resulted from the fastening of a main shaft can not meet the precision requirement of precision measurement. Moreover, the application of a hydraulic locking structure is greatly limited because of an oil leakage problem which is difficult to solve. The locking mechanism of a precision indexing device is composed of a main shaft 1 installed in a casing 2 and a locking sheet 10 matched with the main shaft 1, wherein a fixed plate 11 is installed behind the locking sheet 10, a pressing sheet 9 is fixed on the casing 2, the locking sheet 10 is arranged outside the pressing sheet 9, a threaded rod 5 is installed outside the locking plate 6 and a locking spanner 3 is installed on the threaded rod 5. The utility model is suitable for occasions which require high precision measurement.
Description
Technical field: the utility model relates to a kind of retaining mechanism of precision dividing apparatus.
Background technology: existing precision dividing apparatus retaining mechanism is when measuring, and the locking variation is bigger, and caused indicating value changed when main shaft was fastening, did not satisfy the required precision of accurate measurement.And hydraulic locking mechanism because the leakage of oil problem is difficult to solve, makes its application restricted greatly.
Summary of the invention:
The technical problems to be solved in the utility model: a kind of precision dividing apparatus retaining mechanism that overcomes the weak point of existing precision dividing apparatus locking device is provided.
The technical scheme that addresses the above problem:
The precision dividing apparatus retaining mechanism, its composition comprises: be contained in the stay that the main shaft in the housing cooperates with described main shaft, after the described stay fixed head is housed, compressing tablet is fixed on the housing, described compressing tablet is outward described stay, described latch is equipped with screw rod outward, and the locking spanner is housed on the described screw rod.
Above-mentioned precision dividing apparatus retaining mechanism, described screw rod are contained in the described housing, between described screw rod and the described housing back-moving spring are housed.
Above-mentioned precision dividing apparatus retaining mechanism is equipped with ball-head cover on the described screw rod, and bulb one side of described ball-head cover is set in the described housing, and its opposite side withstands on the axle of described locking spanner.
Beneficial effect compared with prior art:
1. of the present utility model simple in structure, easy to process.
2. locking variation of the present utility model is little, and good stability, can satisfy high-precision measurement.
3. the utility model improves the certainty of measurement of angle, has designed brake disc locking device, and caused indicating value variation reached 1.5 when main shaft was fastening " in, reached the national standard requirement, measure the efficient height.

Below in conjunction with the concrete embodiment of description of drawings:
Embodiment 1.
The precision dividing apparatus retaining mechanism, its composition comprises: be contained in the stay 10 that the main shaft 1 in the housing 2 cooperates with described main shaft 1, after the described stay 10 fixed head 1 is housed, compressing tablet 9 is fixed on the housing 2, outside the described compressing tablet 9 is described stay 10, outside the described latch 6 screw rod 5 is housed, locking spanner 3 is housed on the described screw rod 5.
During locking, with the rotation of set lever 3 clockwise directions, latch 6 is rotated counterclockwise around button 7 under the promotion of handle 3, the compressing tablet 9 that its boss will be fixed on the housing 2 is pressed on the fixed head 11 firmly with the stay 10 that is fixed on the main shaft 1, thereby main shaft 1 is locked.
When unclamping, set lever 3 rotation counterclockwise makes latch 6 boss leave compressing tablet 9 and stay 10.The big I of coupling mechanism force is adjusted by the position of two spacer pins of handle 3.
Embodiment 2:
Precision dividing apparatus retaining mechanism, described screw rod 5 are contained in the described housing 2, between described screw rod 5 and the described housing 2 back-moving spring 8 are housed.
Embodiment 3:
The precision dividing apparatus retaining mechanism is equipped with ball-head cover 12 on the described screw rod 5, and bulb one side of described ball-head cover 12 is set in the described housing 2, and its opposite side withstands on the axle of described locking spanner 3.
