Description

Engine balancer power shaft machining tool

Technical Field

The utility model relates to a clamping frock field.

Background

The engine is the heart of the automobile and provides power for the walking of the automobile, the automobile enters the public families in the common city and becomes the economic development form of the consumption content of daily life, the main part for determining the power and safety performance of the automobile is the engine, therefore, the quality of the power shaft of the engine balancer is extremely important, the shaft part is the very common part in the mechanical industry and also the very important part, the power shaft is the torque transmission part in motion, the manufacturing process level and the product quality directly influence the assembly quality, the shape error precision directly influences the motion performance and the service life of the machine, the understanding of people on the safety performance is gradually improved, so that the requirement of customers on the size of the power shaft of the engine balancer is higher, the workpiece is manually placed into a chuck for positioning processing by the power shaft of the engine balancer before, the precision is low, and the surface roughness is not enough, the defects of poor reliability of position degree and the like cannot meet the precision requirement of a client.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a simple structure, the precision is high, and stability is good, can improve processingquality, reduces the engine balancer power shaft processing frock of disqualification rate.

The utility model discloses it is main including base plate, oil pressure corner lower pressure jar, backup pad and clamp plate.

Wherein, be equipped with locating plate, a set of oil pressure corner lower pressure jar and a set of backup pad on the base plate, be equipped with the recess in the backup pad. And the two supporting plates are respectively provided with a pressing plate. The locating plate is arranged on the outer side of the supporting plate. After the pressing arms of the two oil pressure corner lower pressure cylinders rotate, the pressing arms can rotate to the upper part of the pressing plate and then vertically move downwards to compress the workpiece.

Further, the pressing plate is fixed on the upper surface of the supporting plate through a rotating shaft, so that the pressing plate can rotate.

Further, a pull rope is arranged between the two pressing plates.

Further, the support plate is a V-shaped block.

The utility model discloses when using, in the manual work puts into the V type piece with the work piece, the cylinder drive gives the work piece location with work piece axle and locating plate contact, and the clamp plate is pressed on the work piece, and the pressure arm that the jar was pressed down to the oil pressure corner is rotatory to the clamp plate on, and the pressure arm that the jar was pressed down to the oil pressure corner pushes down the clamp plate, fixes the work piece axle, processes the work piece. After the machining is finished, the pressing arm of the oil pressure corner lower pressure cylinder rotates to be away from the position of the pressing plate, the pressing plate can be rotated by manually pulling the pull rope, the finished shaft is taken out, and the next shaft to be machined is placed into the V-shaped block to perform reciprocating work.

Compared with the prior art, the utility model have following advantage: simple structure, high precision, good stability, and can improve processing quality and reduce reject ratio.

Detailed Description

In the schematic diagram of the present invention shown in fig. 1, a positioning plate, a set of oil pressure corner lower pressure cylinder and a set of V-shaped blocks 2 are disposed on a base plate 1, and two V-shaped blocks are respectively provided with a pressing plate 3. A pull rope 4 is arranged between the two press plates. The positioning plate 5 is arranged on the outer side of the supporting plate. After the pressing arms of the two oil pressure corner lower pressure cylinders 6 rotate, the pressing arms can rotate to the upper part of the pressing plate and then vertically move downwards to compress the workpiece.

In the schematic sketch shown in fig. 2 and fig. 3 of the utility model, in the V type piece was put into to the work piece, the work piece location was given with work piece axle and locating plate contact to the 8 drives of cylinder, and the clamp plate is pressed on work piece 7, and the pressure arm that the pressure jar was pressed down to the oil pressure corner is rotatory to the clamp plate on, and the clamp plate is pressed down to the pressure arm that the pressure jar was pressed down to the oil pressure corner, fixes the work piece axle, processes the work piece.
