Description
Technical field
The present invention relates to a kind of mechanical field, specifically a kind of rail wagon brake cylinder push rod milling medial launder fixture.
Background technology
The current most of vehicle of current railway freight-car mainly uses sealed brake cylinder, and brake cylinder hanger hangs over body frame bottom, and during braking, piston rod is pushed out, and piston rod promotes brake cylinder push bar again, drives brake rigging to play braking action; During alleviation, in piston rod retraction checking cylinder, brake cylinder push bar just loses thrust, and vehicle is alleviated.Therefore, brake cylinder push bar is a strength member on Vehicular brake device.So crudy, the production efficiency in order to ensure brake cylinder push bar, the fixture of design specialized is needed to equip to complete workpiece machining.But the fixture of brake cylinder push bar milling medial launder is Welding Structure at present, yielding, and easy to wear after long-time use, affect brake cylinder push bar crudy, production efficiency.
Summary of the invention
In order to the deficiency that the fixture overcoming existing brake cylinder push bar milling medial launder is yielding, easy to wear, the invention provides a kind of rail wagon brake cylinder push rod milling medial launder fixture, this rail wagon brake cylinder push rod milling medial launder fixture accurate positioning, convenient mounting and clamping, clamping are firm, not yielding, safe and reliable.
Technical scheme of the present invention is: a kind of rail wagon brake cylinder push rod milling medial launder fixture, comprises base plate, base plate is fixed with respectively left riser, middle riser, a right riser, right two risers, and wherein a right riser longitudinally aligns with right two risers; Described left riser has been threaded left screw rod, middle riser has been threaded middle screw rod, a right riser is connected with a right alignment pin, right two risers are connected with right two alignment pins, and the axis direction of described left screw rod, middle screw rod, a right alignment pin, right two alignment pins is longitudinally.
Described left screw rod and middle screw rod lay respectively at brake cylinder push bar both sides, and the described right side one alignment pin and right two alignment pins lay respectively at brake cylinder push bar both sides, and the endoporus of the two diameter and brake cylinder push bar medial launder both sides coincide.
The present invention has following beneficial effect: owing to taking such scheme, brake cylinder push bar is clamped between two screw rods and two alignment pins by this fixture, and due to screw rod, alignment pin is adjustable, make it can adapt to the brake cylinder push bar of different automobile types, different size, also solve the problems such as forging material type is inclined, tolerance is large, allowance is large, accurate positioning, clamping firmly, convenient mounting and clamping, safe and reliable, can rapid processing during production in enormous quantities, improve production efficiency, ensure product quality, bring considerable economic benefit.
Accompanying drawing explanation
Fig. 1 is front view of the present invention;
Fig. 2 is top view of the present invention.
The left screw rod of 1-in figure, the left riser of 2-, the left screw of 3-, 4-base plate, riser in the middle of 5-, the right riser of 6-, the right alignment pin of 7-, right two alignment pins of 8-, the right screw of 9-, right two risers of 10-, 11-nut, 12-middle screw rod.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
Shown in Fig. 1, Fig. 2, a kind of rail wagon brake cylinder push rod milling medial launder fixture, comprise base plate 4, base plate 4 is fixed with respectively left riser 2, middle riser 5, a right riser 6, right two risers 10, wherein a right riser 6 longitudinally aligns with right two risers 10, brake cylinder push bar is between a right riser 6 and right two risers 10, and left riser 2 is positioned at brake cylinder push bar both sides with middle riser 5.Described left riser 2 is welded with left screw 3, left screw 3 has been threaded left screw rod 1, middle riser 5 has been threaded middle screw rod 21, a right riser 6 is connected with a right alignment pin 7, right two risers 10 are welded with right screw 9, right screw 9 has been threaded right two alignment pins 8, and the axis direction of above-mentioned left screw rod 1, middle screw rod 21, a right alignment pin 7, right two alignment pins 8 is longitudinally, namely perpendicular to the axis direction of brake cylinder push bar.Because left riser 2 lays respectively at brake cylinder push bar both sides with middle riser 5, a right riser 6 lays respectively at brake cylinder push bar both sides with right two risers 10, therefore, left screw rod 1 lays respectively at brake cylinder push bar both sides with middle screw rod 12, a right alignment pin 7 lays respectively at brake cylinder push bar both sides with right two alignment pins 8, and the endoporus of the two diameter and brake cylinder push bar medial launder both sides coincide.
When milling brake cylinder push bar medial launder, fixture is placed on centering on milling machine workbench, ensures that the center of fixture is parallel with milling machine X-direction; Then the hole crossed with Product processing is for positioning datum, and the endoporus of brake cylinder push bar medial launder both sides is matched with a right alignment pin 7, rotates right two alignment pins 8, the left screw rod 1 of rear adjustment to be clamped and middle screw rod 12, determine clamping work pieces; Then process inside groove to 28 ± 1 size with special elongated bar milling cutter and ensure two uniform wall thickness.
This fixture due to left screw rod 1, middle screw rod 12, a right alignment pin 7 and right two alignment pins 8 adjustable, make it can adapt to the brake cylinder push bar of different automobile types, different size, also solve the problems such as forging material type is inclined, tolerance is large, allowance is large, accurate positioning, clamping firmly, convenient mounting and clamping, safe and reliable, can rapid processing during production in enormous quantities, improve production efficiency, ensure product quality, bring considerable economic benefit.
