Description
Technical field
The present invention relates to a kind of cam axial trough Machining of Curved Surface special fixture, belongs to cam axial trough Machining of Curved Surface equipment and technology neck
Domain.
Background technology
The processing of cam axial trough curved surface due to be product trial-production, small lot production, generally using vertical machining center
Bed is, it is necessary to the special clamping tooling fixture of Aided design.This processing method is time-consuming in camshaft parts fixation, the process-cycle
Long, cost input is larger, and labor productivity is low, is not suitable with and turns batch large batch of production, part positioning is also inaccurate, and quality is not
Stablize.
The content of the invention
It is easy to use the present invention provides a kind of simple in structure to solve the prior art there are technical problem, can be direct
It is fixed on milling machine, clamping operation is easy, the high cam axial trough Machining of Curved Surface special fixture of production efficiency.
To achieve the above object, the technical solution adopted in the present invention is cam axial trough Machining of Curved Surface special fixture, including
Base, the base are provided at both ends with bearing, axle sleeve are slidably fitted with the bearing of one end, are provided with and turn on other end bearing
Axis, is fixed with master cam on the axle sleeve, scroll chuck is slidably fitted with the shaft, is further fixed on justifying on the base
Pin, is provided with bearing on the straight pin, the bearing is in contact with master cam, installs and top is provided with the bearing of axle sleeve
Push oil cylinder, the piston rod of the pipe bending cylinder are used to promote master cam；It is provided with the shaft and is rotated for drive shaft
Driving mechanism.
Preferably, the base is bolted on milling machine.
Preferably, the driving mechanism includes gear, rack and sliding slot, and the gear is installed on the end of shaft, described
Sliding slot is provided with below gear, the sliding slot is fixed on base, and rack, the rack and pinion are slidably fitted with sliding slot
It is meshed, the drive cylinder for drive rack movement is provided with the rack.
Compared with prior art, the present invention has following technique effect：The configuration of the present invention is simple, it is easy to use, directly will
Fixture is fixed on plain-milling machine, being simple to manufacture of part, and clamping operation is easy, it is not necessary to Programming, single-piece manufacturing time
Shorten, manufacture cost is greatly reduced；And it is simple to manufacture process, production efficiency is high, disclosure satisfy that mass production；Positioning
Clamping precision is high, and workmanship is stablized, good product consistency.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.

Accompanying drawings and embodiments are closed, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only
To explain the present invention, it is not intended to limit the present invention.
As shown in Figure 1, cam axial trough Machining of Curved Surface special fixture, including base 1, base 1 are provided at both ends with bearing 2,
Axle sleeve 3 is slidably fitted with the bearing of one end, shaft 4 is provided with other end bearing, master cam 5, shaft are fixed with axle sleeve 3
Scroll chuck 6 is slidably fitted with 4, scroll chuck is fixed in shaft by key connection, ensures that scroll chuck can be moved axially
It is dynamic, and synchronous rotating shaft rotates, and is further fixed on straight pin 7 on base 1, bearing 8, bearing 8 and master cam are provided with straight pin 7
5 are in contact, and install and pipe bending cylinder 9 is provided with the bearing 3 of axle sleeve, and the piston rod of pipe bending cylinder 9 is used to promote master cam 5；
The driving mechanism rotated for drive shaft is provided with shaft 4.
Wherein, driving mechanism includes gear 11, rack 12 and sliding slot 13, and gear 11 is installed on the end of shaft 4, gear 11
Lower section be provided with sliding slot 13, sliding slot 13 is fixed on base 1, and rack 12, rack 12 and gear are slidably fitted with sliding slot 13
11 are meshed, and the drive cylinder for drive rack movement is provided with rack 12.
When in use, directly base 1 is fixed on milling machine by bolt 10, by camshaft to be processed inserting to axle sleeve
It is interior, and stretch out outside axle sleeve, fixed by scroll chuck, lock-screw is then fixed on axle sleeve, axle sleeve and camshaft are fixed.
Pipe bending cylinder stretches out, and the piston rod of pipe bending cylinder is withstood one end of master cam, and master cam drives axle sleeve, scroll chuck to move
Dynamic, the master cam other end is in contact with bearing, and the end face being in contact with bearing is provided with protrusion of different shapes, specifically can be with
Design is made choice according to the curved surface of actual processing, so as to change the movement locus of master cam, realizes adding for different curve groove
Work.Rack moves under the action of drive cylinder, and drive gear rotates, so that cam axle to be processed is controlled, while imitative
Under the action of shape cam, movement locus constantly changes, so as to be processed into axial trough curved surface.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should all wrap within the scope of the present invention.
