Description
Technical field
The utility model relates to a kind of mechanical field, specifically a kind of fixture for car pillar bush hole.
Background technology
In China domestic railway 30t axle heavy cargo vehicle brake except other parts, generally also comprise two brake beams, each brake beam frame is provided with a pillar (as Fig. 1).In order to increase pillar service life, wear-resisting lining need be press-fited at pillar and brake lever connection hole.Bush hole on current pillar adopts the processing method of line, bore hole, but due to shortcomings such as pillar workpiece are cast blank material, and current processing technology exists Workpiece fixing low precision, crudy is wayward, working (machining) efficiency is low, operator's labour intensity is large.
Summary of the invention
In order to overcome, existing pillar bush hole setting accuracy on work is poor, the uppity deficiency of crudy, the utility model provides a kind of fixture for car pillar bush hole, this fixture location being used for car pillar bush hole is reliable, reduce processing cost owing to adopting lathe process, production efficiency is high, product percent of pass is high, convenient operation.
The technical solution of the utility model is: a kind of fixture for car pillar bush hole, comprise base, chassis support, described chassis support is welded on the side of base, described base top is connected with wearing plate, wearing plate top is fixed with pillar workpiece by two alignment pins, and both sides, wearing plate top are fixed with back-up block respectively, and two back-up block tops are fixed with pressing plate respectively, and be connected with carrying bolt in the middle part of pressing plate, be fixed on wearing plate by bolt block bottom carrying bolt; Carrying bolt is connected with in the middle part of described chassis support.
Be fixed with nut seat in the middle part of described chassis support, nut seat has been threaded carrying bolt, and chassis support top is fixed with balancing weight.
The utility model has following beneficial effect: owing to taking such scheme, this fixture is fixed on lathe spindle by chassis support, the location of pillar workpiece is realized by two alignment pins, carrying bolt and pressing plates, ensure that location is reliable, make it possible to adopt lathe process bush hole, thus cut down finished cost, enhance productivity and product percent of pass, convenient operation, holder maintenance is easy simultaneously, substantially increases the economic benefit of enterprise.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in Fig. 2, Fig. 3, a kind of fixture for car pillar bush hole, comprises base 1, chassis support 2, and described chassis support 2 is welded on the side of base 1, and chassis support 2 is disc, is fixed on lathe spindle by it by fixture entirety, can rotate with main shaft.Described base 1 top is connected with wearing plate 3, and be bolted between base 1 and wearing plate 3, wearing plate 3 is replaceable.Wearing plate 3 top is fixed with pillar workpiece by two alignment pins 4, and alignment pin 4 passes in two holes that on pillar workpiece, a procedure processes, and realizes pillar horizontal direction location.Both sides, wearing plate 3 top are fixed with back-up block 7 respectively, and back-up block 7 is fixed on two ends of wearing plate 3, and two back-up block 7 tops are fixed with pressing plate 10 respectively, and one end of two pressing plates 10 is fixed on back-up block 7, and the other end is unsettled.Be connected with carrying bolt 6 in the middle part of pressing plate 10, be fixed on wearing plate 3 by bolt block 5 bottom carrying bolt 6, by the nut on rotational support bolt 6, pressing plate 10 can be pressed down, thus by pillar Work-sheet pressing, realize longitudinal register.Nut seat 8 is fixed with in the middle part of described chassis support 2, nut seat 8 has been threaded carrying bolt 9, the adjustable in length that carrying bolt 9 stretches out, and its outer end withstands on pillar, avoid pillar to tilt, also can prevent from adding man-hour because of the slight flutter effect crudy of pillar.Chassis support 2 top is fixed with balancing weight 11, crank when avoiding this fixture to rotate with main shaft.
When needing car bush hole 12 after a procedure on pillar completes, this fixture is fixed on lathe spindle by chassis support 2.Pillar workpiece is placed on wearing plate 3, by two alignment pins 4 through two holes on pillar and base 1; Regulate fishbolt 6, make pressing plate 10 compress pillar, namely complete the positioning and clamping of pillar; Regulate carrying bolt 9, make the end of carrying bolt 9 withstand on pillar side, lathe car bush hole 12 can be adopted.
