Abstract
The utility model belongs to the technical field of the toolmaking, concretely relates to grinding forming mechanism is slightly bored to screw tap, cam mechanism include ejector pin, cam, axle, the profile of cam be three lamella formulas, the lift journey of each lamella corresponds a cross section profile of tooth of screw tap processing, the bolt -up is epaxial for the cam for the restriction cam is in the axial removal of axle. The ejector pin lower extreme be located the wheel profile surfaces of cam, the kicking block on the swing mechanism is connected to the upper end, the ejector pin overcoat has the closing cap. The utility model provides a plant grinding forming mechanism is slightly bored to screw tap, drive cam pivoted motor and drive screw tap pivoted motor as long as the same model of selection guarantees that the rotational speed is the same, just can realize required processing requirement, need not to control motor rotation number's control system, reduced the cost of production facility.
Description
Technical field
This utility model belongs to cutter manufacture technical field, and in particular to a kind of screw tap Zhui Shao grinding-shapings mechanism.
Background technology
Screw tap is a kind of cutter of machining internal thread, and main cutwork is undertaken by cutting cone.Cutting cone cross section
The cross section profile of tooth of three lobe cutting edges is identical, and its cutting edge cross-sectional profiles camber line is spiral of Archimedes.Often at present
Screw tap Zhui Shao grinding-shapings mechanism, needs complicated mechanical construction and control system progressively to coordinate, is sequentially completed three lobes and cuts
Cut the molding feed motion of sword section, cutter manufacture precision and low production efficiency, cutter manufacture high cost.
Utility model content
The purpose of this utility model is the cost for reducing production equipment, there is provided a kind of lobe cutting edge one of cutting cone cross section three
Individual motion cycle one-shot forming, the screw tap cone slightly grinding-shaping machine for reducing the adjustment stock-removing machine time in machining feed motion
Structure.
To solve above-mentioned technical problem, the technical solution of the utility model is：
Screw tap Zhui Shao grinding-shapings mechanism, including swing seat mechanism and cam mechanism；Described cam mechanism includes push rod, convex
Wheel, axle, the profile of described cam is three-clove style, and the lifting journey of each lobe corresponds to a cross section profile of tooth of screw tap processing；It is convex
Wheel bolt is fastened on axle, to limit movement of the cam in axle axial direction.Described push rod lower end is located at the contoured surface of cam
On, the jacking block on upper end connection swing mechanism is cased with capping outside push rod.
Preferably, the cam is coordinated between centers by flat key, to limit cam in the circumferential movement of axle.
Preferably, push rod lower end is provided with roller, and roller is contacted with the contoured surface of cam, to reduce rubbing when moving
Wipe.
The beneficial effects of the utility model are：Provided by the utility model kind of screw tap Zhui Shao grinding-shapings mechanism, drives
As long as the motor of cam rotation selects same model with the motor for driving screw tap to rotate, it is ensured that rotating speed is identical, so that it may needed for realizing
Processing request, without the need for the control system of controlled motor rotating speed, reduce the cost of production equipment.
Description of the drawings
Fig. 1 is the structural representation of this utility model screw tap Zhui Shao grinding-shapings mechanism；
Fig. 2 is the explosive view of this utility model cam mechanism；
Fig. 3 is the structural representation of this utility model cam mechanism.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described further with specific embodiment：
As shown in Figure 1, Figure 2 and Figure 3,1 liang of screw tap Zhui Shao grinding-shapings mechanism, including cam mechanism 2 and swing mechanism are big
Module, cam mechanism 2 and swing mechanism 1 are linked together by the extension spring of side so that both persistently keep contact when working.
The top screw tap equipped with cone to be ground slightly of 1 liang of swing mechanism, the top connection centrage of 1 liang of swing mechanism and whole swing mechanism
The axle center line that rotationally supports have certain distance, the promotion for being fixed in jacking block 3 on swing mechanism 1 in the push rod 5 of cam mechanism 2 is made
The axle center line that rotationally supports around swing mechanism with makees intermittent oscillation；Three-clove style cam 7 in cam mechanism 2 is circumferential by key 6
Fixed blending bolt 8, nut 11, pad 10 realize axial restraint with axle 9, and capping 4 protects push rod slidably.Watch in feeding
Under taking motor effect, three-clove style cam 7 is driven to rotate, the roller 12 contacted with cam 7 drives push rod 5 that motion is passed to into oscillating machine
Structure 1.
One of ordinary skill in the art will be appreciated that embodiment described here is to aid in reader and understands this reality
With new principle, it should be understood that protection domain of the present utility model is not limited to such especially statement and embodiment.
One of ordinary skill in the art these technology enlightenments can make various without departing from this practicality according to disclosed in this utility model
New other substantive various concrete deformations and combination, these deformations and combination are still in protection domain of the present utility model.
