Abstract

The invention relates to milling equipment for intermediate stroke grooves of pistons of brake pumps. The milling equipment comprises a framework, a fixture and a machining power head, the machining power head consists of a milling head and a drilling head which can be switched to a machining position, the fixture is arranged on a base and can move up and down on the base, the movement distance of the fixture is equal to the length of a stroke groove to be machined, the machining power head is disposed on one side of the fixture, and an apex device is disposed on the other side of the fixture. When a milling cutter on the milling head is located at the machining position, an apex on the apex device and the milling cutter are concentric, and the apex can be abutted to the central point of the end of the milling cutter. By the aid of the apex device, the apex is abutted to the central point of the end of the milling cutter during milling machining, a suspended free end of the milling cutter is radially supported, accordingly, the quantity of radial swinging of the milling cutter which rotates at high speed is reduced, and shape precision and surface smoothness of the machined groove are greatly improved. Under the condition that identical machining precision is obtained, the milling equipment with the structure can greatly reduce process cost as compared with a conventional independent finish machining mode.

Description

A kind of brake pump piston middle of stroke groove milling device
 
Technical field
The present invention relates to a kind of combination process equipment, especially relate to a kind of brake pump piston middle of stroke groove milling device.
 
Background technology
For some automobile-used brake pump, the body of its piston is cylindric (wherein some is stepped), and the middle of stroke groove axially is set on the circumference, and this middle of stroke groove is a bar-shaped trough, and runs through body; The middle of stroke groove cooperates with pin on being located at valve body, plays the effect of guiding and control piston shift motion.In order to process the middle of stroke groove, generally adopt the machining mode of milling, but because the middle of stroke groove is the groove that radially runs through piston only; Darker, so difficulty of processing is bigger, machining accuracy is lower; Lower precision, it is suitable inadequately sliding that piston is moved, and makes the braking pump performance be affected.
 
Summary of the invention
Main purpose of the present invention provides a kind of milling device that improves middle of stroke groove machining accuracy.
Above-mentioned technical problem of the present invention mainly is able to solve through following technical proposals: a kind of brake pump piston middle of stroke groove milling device comprises frame, anchor clamps and processing dynamics head; This processing dynamics head comprises milling head and the drilling head that can switch to Working position; These anchor clamps are located on the base and can on base, be moved up and down, and the distance that moves equals the flute length of stroke groove to be processed; It is characterized in that: the processing dynamics head is located at a side of anchor clamps, is provided with Finial device at the opposite side of anchor clamps; When the milling cutter on the milling head was in Working position, the top and milling cutter on the Finial device was in concentric, and can withstand the end center point of milling cutter.Finial device is set, when Milling Process, the top milling cutter end center point of withstanding, the free end that milling cutter is suspended obtains radial support, thereby makes the milling cutter of rotation at a high speed reduce the amount of radially wobbling, and significantly improves the form accuracy and the surface smoothness of institute's working groove; With respect to routine carry out accurately machined mode separately, under the situation that obtains same machining accuracy, this structure can significantly reduce the technology cost.
For the ease of the location of the clamping and the milling cutter of workpiece, as preferably, described Finial device is collapsible structure.
The processing of the flute length of middle of stroke groove, the mobile feeding of leaning on anchor clamps, as preferably, described base is provided with slide rail, and drives the hydraulic cylinder that anchor clamps move up and down along slide rail.This structure moves comparatively smoothly, be easy to control the length of working groove, and cost is lower.
For the piston of different size, wherein between the stroke groove have different specifications, often need adjust the home position of processing dynamics head, for easy to adjust, as preferably, described processing dynamics head is provided with can guide it and do the guide rail that moves up and down.
As preferably, described anchor clamps comprise clamp body and clamping cylinder.Clamp part to be processed through clamping cylinder, clamping force is big, can adapt to the needs of milling; And reliable clamping, operation are fast.
Therefore, that the present invention has is rational in infrastructure, be easy to characteristics such as making, and especially having adopted Finial device is the structure that milling cutter provides support, and can improve middle of stroke groove machining accuracy.
 
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present invention.
 
The specific embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically technical scheme of the present invention.
Embodiment: a kind of brake pump piston middle of stroke groove milling device shown in accompanying drawing 1, comprises frame 12, anchor clamps 2 and processing dynamics head.Anchor clamps 2 are located on the base 7 and can on base 7, be moved up and down, and the distance that moves equals the flute length of stroke groove to be processed.
The processing dynamics head has the milling head 3 and drilling head 4 of changeable position; For the middle of stroke groove, generally be earlier drilling head 4 to be switched to Working position boring, switch milling head 3 thereafter and carry out milling.
The processing dynamics head is located at a side of anchor clamps 2, is provided with Finial device at the opposite side of anchor clamps 2; When the milling cutter on the milling head 4 was in Working position, top 1 on the Finial device was in concentric with milling cutter.Finial device is collapsible structure, when milling cutter gets into Working position, and top stretching out, the center, end of withstanding milling cutter rotates with milling cutter.
When changing anchor clamps, the existence of processing dynamics head needs the possibility of fine setting; In addition, for the piston of different size, wherein between the stroke groove have different specifications, often need adjust the home position of processing dynamics head; Therefore, for easy to adjust, the processing dynamics head is provided with can guide it and do the guide rail 5 that moves up and down.
The flute length processing of middle of stroke groove, the mobile feeding of leaning on anchor clamps.Base 7 is provided with slide rail 8, and drives the hydraulic cylinder 8 that anchor clamps 2 move up and down along slide rail 8.Driving the distance that anchor clamps 2 move up and down, is exactly the length of the groove of processing.The control of the size of displacement for example can rely on block, limit switch or the like conventional means to realize.Anchor clamps 2 comprise clamp body and clamping cylinder 6.
During use, brake pump piston to be processed is put into anchor clamps, clamping cylinder 6 clamps workpiece; The drilling head of processing dynamics head gets into Working position, and holes, and after the completion, drilling head leaves, and milling head gets into Working position, and the top center, end of withstanding milling cutter of stretching out immediately begins to carry out milling; In the process of milling, the Driven by Hydraulic Cylinder anchor clamps are upwards done feed motion, thereby accomplish the processing of groove.
Need to prove; Principle of the present invention is that Finial device is set, and withstands the milling cutter end center point, and the free end that milling cutter is suspended obtains radial support; Thereby make the milling cutter of rotation at a high speed reduce the amount of radially wobbling, significantly improve the form accuracy and the surface smoothness of institute's working groove; Term position up and down as herein described is a direction shown in the drawings, only is used for convenient narration, does not constitute the qualification of entire mechanism principle.
