Description
Technical field
The present invention relates to a kind of boring cutter automatic feed mechanism.
Background technology
Boring processing, which is typically considered, to be adapted to the ideal in the processing precise hole on various different sizes and shapes workpiece and adds
Work mode.In order to adapt to the need for improving constantly productivity ratio, the design of borer is also in improvement of constantly bringing forth new ideas.Hole boring cutter itself
Also there are some shortcomings, the imbalance of high speed rotation, centrifugal force and the boring head of boring head in itself may all cause larger vibration, knife bar
Overhanging distance, causes cutting stability to reduce, and production efficiency is relatively low.The cutter head of other existing cylindrical boring cutter is not threaded,
The advance of cutter head is to hold out against cutter head rear end by the adjusting screw adjusted on boring bar and realize, and the rear end of cutter head can not be direct
Nut realization is held out against by adjusting, but first jacking nut is retreated and causes have necessarily between cutter head rear end and jacking nut
Withdrawing head intermittently or after with hand is pressed, such regulation mode of operation is sufficiently complex and degree of regulation is not high, and hole boring cutter
Head is unable to self-locking, and cutter head can loosen during boring, finally influence product quality.
The content of the invention
It is an object of the invention to provide a kind of boring cutter automatic feed mechanism, to overcome the deficiencies in the prior art, work is improved
Efficiency and product processing quality.
The present invention technical solution be：Boring cutter automatic feed mechanism, is provided with rear pressing cover above boring cutter bar tool bore, after
Gland is coordinated with boring cutter bar by bolt, and bearing pin is connected through a screw thread with rear pressing cover, is abided by post through rear pressing cover through hole and is matched somebody with somebody therewith
Close, bearing, balancing weight and cam are fitted loaded on abiding by post above bearing with rear pressing cover, and balancing weight, balancing weight are provided with below bearing
It is to be provided with boss below screw type boss, balancing weight that lower section, which is provided with above cam, cam, and disc spring is embedded in the endoporus of cam, dish
Spring base is provided with below spring, spring base is coordinated with broach shell cylinder by bolt, and it is lateral opening that the spring upper end on broach shell cylinder is located at broach shell cylinder
Interior, lower spring end is located in the spring eye of boring cutter bar, and boring cutter is enclosed on blending bolt in broach shell cylinder and fixed in both sides.
The present invention compared with the existing technology with simple in construction, can realize boring cutter certainly by the cooperation of balancing weight and cam
Dynamic feed and positioning, prevent boring cutter from loosening, and improve production efficiency, and process is stable, high reliability.
Brief description of the drawings
Fig. 1 is the schematic diagram of the embodiment of the present invention.
In figure：1st, boring cutter bar, 2, abide by post, 3, rear pressing cover, 4, bearing, 5, bearing pin, 6, balancing weight, 7, cam, 8, disc spring, 9,
Spring base, 10, broach shell cylinder, 11, boring cutter, 12 springs.
Embodiment
Embodiment is further illustrated below in conjunction with the accompanying drawings：
Rear pressing cover 3 is provided with above the tool bore of boring cutter bar 1, the upper end of rear pressing cover 3 is provided with counter sink, and lower end is provided with screw hole, rear pressure
Lid 3 is coordinated with boring cutter bar 1 by bolt, and bearing pin 5 is provided with counter sink, and bearing pin 5 is connected through a screw thread with rear pressing cover 3, abides by post 2 and wear
Later the through hole blending bolt of gland 3 coordinates, and bearing 4, balancing weight 6 pass through with cam 7 and abide by post 2, the top of bearing 4 and rear pressing cover 3
Laminating, the lower section of bearing 4 is provided with balancing weight 6, and the lower section of balancing weight 6 is provided with cam 7, and the top of cam 7 is screw type boss, balancing weight 6
Lower section be provided with boss, disc spring 8 is embedded in the endoporus of cam 7, and the lower section of disc spring 8 is provided with spring base 9, and spring base 9 is provided with counter sink,
Spring base 9 is coordinated with broach shell cylinder 10 by bolt, and the upper end of spring 12 on broach shell cylinder 10 is lateral opening interior positioned at broach shell cylinder 10, spring 12
Lower end is located in the spring eye of boring cutter bar 1, and boring cutter 11 is enclosed on blending bolt in broach shell cylinder 10 and fixed in both sides.
When undressed, the boss of the lower section of balancing weight 6 is located on the bottommost of the spiral boss of cam 7, and broach shell cylinder 10
Spring 12 be in compressive state.When needing processing, the high-speed rotation of boring cutter bar 1, when reaching certain rotating speed, is enclosed on and abides by post
Balancing weight 6 on 2 in the presence of inertia force along the spiral prominence table top of cam 7 from bottommost upward sliding, when balancing weight 6 is encountered
Bearing pin 5 on rear pressing cover 3 and stop motion, so that the disc spring 8 in the groove of cam 7 is compressed, are fixed together with spring base 9
Spring 12 on broach shell cylinder 10 compresses under the elastic force of disc spring 8, so that the boring cutter 11 being fixed in broach shell cylinder 10 is extruded, realizes
Boring cutter goes out knife.
