Abstract
The utility model discloses a be fit for dynamic balance anchor clamps of taking shaft yoke class transmission shaft, mainly including drive setting element, location balancing piece, locating pin, bolt, location balancing piece front end passes through locating pin and bolt fixed connection drive setting element, is provided with the location spline on the drive setting element internal diameter, and location balancing piece internal diameter is the unthreaded hole. The unthreaded hole of the inner diameter of the positioning balance piece is matched with a workpiece in a large-diameter centering mode. The utility model adopts spline fit positioning instead of spline driving and unthreaded hole positioning, and improves the manufacturing precision of the clamp by changing the structure of the clamp, thereby satisfying the use requirement of dynamic balance; the problem that about 5% of original transmission shafts cannot be balanced is solved, and the number of the regular products is increased from 180 to 240.
Description
Technical Field
The utility model relates to a field of transmission shaft assembly, concretely relates to dynamic balance anchor clamps that are fit for taking shaft fork class transmission shaft.
Background
In the dynamic balance fixture tool with the shaft fork transmission shaft in the prior art, a dynamic balance base 4 is connected with dynamic balance equipment in a matched mode, a middle part 2 is connected with the dynamic balance base 4 through a bolt part 3, a connecting part 1 is combined with the middle part 2 through interference fit, the connecting part 1 is matched with a workpiece, and due to the fact that the fixture is combined through a plurality of parts, the assembly jumping is difficult to control after assembly. Simultaneously because the internal spline high accuracy of connecting piece 1, the preparation is more difficult, and spline size and concentricity detect also more difficult, and the clearance is great when causing shaft yoke and frock cooperation, can be because the clearance problem makes the transmission shaft be difficult to balance when needing the work piece to cooperate when balanced, influences the balanced precision.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art existence, and provide a dynamic balance anchor clamps that is suitable for tape spool fork class transmission shaft.
The purpose of the utility model is accomplished through following technical scheme: the dynamic balance clamp suitable for the transmission shaft with the shaft fork mainly comprises a driving positioning piece, a positioning balance piece, a positioning pin and a bolt, wherein the front end of the positioning balance piece is fixedly connected with the driving positioning piece through the positioning pin and the bolt, a positioning spline is arranged on the inner diameter of the driving positioning piece, and the inner diameter of the positioning balance piece is a light hole.
The inner diameter of the positioning balance piece is provided with a unthreaded hole which is matched with a workpiece in a large-diameter centering mode.
The utility model has the advantages that: the utility model adopts spline fit positioning instead of spline driving and unthreaded hole positioning, and improves the manufacturing precision of the clamp by changing the structure of the clamp, thereby satisfying the use requirement of dynamic balance; the problem that about 5% of original transmission shafts cannot be balanced is solved, and the number of the regular products is increased from 180 to 240.
Drawings
Fig. 1 is a schematic structural diagram of the prior art.
Fig. 2 is a schematic structural diagram of the present invention.
Description of reference numerals: the device comprises a connecting piece 1, an intermediate piece 2, a bolt piece 3, a dynamic balance base 4, a driving positioning piece 5, a positioning balance piece 6, a positioning pin 7 and a bolt 8.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
example (b): as shown in the attached drawings, the dynamic balance clamp suitable for the transmission shaft with the shaft fork mainly comprises a driving positioning part 5, a positioning balance part 6, a positioning pin 7 and a bolt 8, wherein the front end of the positioning balance part 6 is fixedly connected with the driving positioning part 5 through the positioning pin 7 and the bolt 8, the replacement is convenient and simple, a positioning spline is arranged on the inner diameter of the driving positioning part 5, a workpiece enters the clamp through the positioning spline, the inner diameter of the positioning balance part 6 is a unthreaded hole, the workpiece is further positioned through the unthreaded hole, and the unthreaded hole of the inner diameter of the positioning balance part 6 adopts a large-diameter centering matched workpiece. The manufacturing precision can meet the process requirement more easily.
The utility model discloses adopt the unthreaded hole to fix a position under the centering prerequisite of guaranteeing the major diameter, because the preparation technology and the control means of unthreaded hole all far compare the spline simple that comes, consider balanced required precision, balanced clearance control is in 0.03mm, and the precision of anchor clamps itself needs in 0.015mm, and the unthreaded hole passes through to grind this requirement of completion that processing can be simpler.
It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
