Description

Piston pin hole machine

Technical field:

The invention belongs to the Machining Technology field of piston, be specifically related to a kind of piston pin hole machine.

Background technology:

In the pin-and-hole processing of existing piston, earlier piston is fixed on the retaining ring groove machine clamp of two sides, the processing annular groove is with internal diameter seam location heavy boring pin-and-hole; With internal diameter seam location piston is fixed on precision bored hole on the right boring machine clamp again; At last piston is propped up with skirt section end face and external diameter and being carried on the broach(ing) machine fraising and finishing the processing of piston is handled; Its heavy boring pin-and-hole, retaining ring groove, precision bored hole and fraising processing are finished on four lathes respectively, and existing needs No. four clampings, at least three workman's operations, make workpiece be easy to generate the resetting error, reduced the precision of piston, production efficiency is low, labour intensity is big, defect of high cost.

Summary of the invention:

The objective of the invention is to overcome the defective in the above-mentioned piston process, provide a kind of and reduce labor intensity, enhance productivity and the machining accuracy of piston the piston pin hole machine that reduces production costs.

Technical scheme of the present invention is: a kind of piston pin hole machine bed, form by the rotary table on support and its medium position, it is characterized in that rotary table is fixed on the seat board of location, the location seat board is installed in the rotating shaft upper end, rotating shaft is installed on the support by bearing, the rack piston bar that establish in gear and the support bottom of rotating shaft is meshed, and the hydraulic cylinder piston rod that connector and downside are established in the lower end of rotating shaft joins; Be arranged with two work piece holders on the rotary table; Also be provided with two mechanism and right boring holes mechanism and fraising mechanisms that have heavy boring, clasp, chamfering function on the correspondence position of rotary table both sides support.

Wherein, described two mechanisms that have heavy boring, clasp, chamfering function are made up of the main spindle box on the heavy boring slide, line slideway and the slide unit that are positioned on the support symmetric position of the anchor clamps left and right sides 8,9; All establish the retaining ring groove cutter on the main tapping knife bar of main spindle box 8,9, establish rough bore cutter, rose reamer on the outer end of knife bar.

Described right boring holes mechanism is made up of the main spindle box on the right boring slide, line slideway and the slide unit that are positioned at the anchor clamps left side; Establish half smart hole boring cutter and smart hole boring cutter on the main tapping knife bar of main spindle box.

Described fraising mechanism is made up of the main spindle box on the hinge slide, line slideway and the slide unit that are positioned at the anchor clamps right side; The main shaft knife bar of main spindle box is provided with location cutting blade and expansion reamer sheet.

Described a kind of piston pin hole machine bed is characterized in that course of action is the control of adopting the PLC control system to move.

Because adopt technique scheme, two stations of a clamping can be finished whole operations of piston pin holes such as heavy boring pin-and-hole, chamfering, two ends annular groove, precision bored hole, fraising, and during workpiece loading and unloading, right boring, fraising two-step can normally be processed; Thereby it is low to have a cost, has reduced the error that causes because of resetting, the piston precision height of operating efficiency and processing, the obvious advantage that labour intensity is low.

Description of drawings:

Come technical scheme of the present invention is described further below in conjunction with the drawings and specific embodiments.

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the vertical view of Fig. 1;

The specific embodiment:

With reference to figure 1 and Fig. 2, a kind of piston pin hole machine bed, form by the rotary table 2 on support 1 and its medium position, rotary table 2 is fixed on the seat board 5 of location, location seat board 5 is installed in rotating shaft 3 upper ends, rotating shaft 3 is installed on the support 1 by bearing 4, and the rack piston bar 6 that establish in gear and the support 1 bottom of rotating shaft is meshed, and the hydraulic cylinder piston rod that connector and downside are established in the lower end of rotating shaft 3 joins; Be arranged with two work piece holders 7 on the rotary table 2; Also be provided with two mechanism and right boring holes mechanism and fraising mechanisms that have heavy boring, clasp, chamfering function on the correspondence position of rotary table both sides support 1.

Described two mechanisms that have heavy boring, clasp, chamfering function are made up of the main spindle box 8,9 on the heavy boring slide, line slideway and the slide unit that are positioned on anchor clamps 7 left and right sides support symmetric positions; Establish the retaining ring groove cutter on the main tapping knife bar of main spindle box 8,9, establish rough bore cutter, rose reamer on the outer end of knife bar.

The right boring holes mechanism is made up of the main spindle box 10 on the right boring slide, line slideway and the slide unit that are positioned at anchor clamps 7 left sides; Establish half smart hole boring cutter 11 and smart hole boring cutter 12 on the main tapping knife bar of main spindle box 10.

Fraising mechanism is made up of the main spindle box 13 on the hinge slide, line slideway and the slide unit that are positioned at anchor clamps 7 right sides; The main shaft knife bar of main spindle box 13 is provided with location cutting blade and expansion reamer sheet 14.

The course of action of piston pin hole machine bed is the control of adopting the PLC control system to move.

During use, a workpiece is installed on the anchor clamps of rotary table and clamps, under the control of PLC, the main axis rotation of main spindle box 8,9, and move with slide unit and to finish piston heavy boring pin-and-hole operation, put in place moving on, return after finishing chamfering, annular groove operation more simultaneously; At this moment, after the hydraulic cylinder piston rod of rotating shaft 3 lower ends rises rotating shaft, gear 5 rotations of the rack drives rotating shaft lower end in the support, make the location that descends behind the rotary table Rotate 180 °,

main spindle box

10,13 is started working, finish precision bored hole and fraising two-step successively, can finish a working cycles.
