Abstract
The utility model discloses a pillar drill universal fixture and mainly aims to solve the problems that parts of an existing dust collector and sphere core angle cock are prone to deflecting under the action of cutting force at the drilling time, and therefore a thread bottom hole is not perpendicular to the upper surface of a boring hole, and assembly quality is influenced. The pillar drill universal fixture is characterized in that an ejection rod mechanism (6) is arranged in the middle of a bottom plate (1), an air cylinder (8) is connected with the bottom of the bottom plate (1), a clamping piston (9) is arranged in the air cylinder (8), the upper portion of the clamping piston (9) is connected with the ejection rod mechanism (6), a movable chassis (10) is connected with the bottom of the air cylinder (8) and a permanent magnetic chuck (12) is connected with the bottom of the movable chassis (10) through a fixing bottom plate (11). Due to the fact that the pillar drill universal fixture uses part machining faces as positioning faces so that verticality of the parts is guaranteed and hole drilling quality is improved.
Description
Technical field
The utility model relates to a kind of mechanical field, specifically a kind of cylindrical drill universal fixturing for processing railway freight-car accessory.
Background technology
Stainless steel Combined dust collector and stainless steel A type ball type angle cock are the critical pieces of railroad train braking pipe arrangement, along with the continuous increase of present railway freight-car demand, stainless steel Combined dust collector and stainless steel A type ball type angle cock task amount per month constantly increase.Therefore four holes on four holes on the dust collector body and the cock body adopt same anchor clamps to process because position, size are all identical usually, and drilling operating is processed at radial drill always at present, along with the increase of output is increasing because of the limited production pressure of equipment.
At present dust collector body boring and cock body drilling operating machine at radial drill, dust collector body and cock body taper hole bottom surface are pressed on the base plate when clamping, because the bottom surface is black skin, can not guarantee that part has higher perpendicularity, part is subject to the effect generation skewness of cutting force during boring, cause plane out of plumb on thread Pilot hole and the taper hole, affect assembling quality.Operator's labour intensity is large simultaneously, and production efficiency is lower.
Summary of the invention
Skewness easily occurs in the effect that is subject to cutting force in order to overcome existing dust arrester and ball type angle cock part when holing, cause plane out of plumb on thread Pilot hole and the taper hole, affect the deficiency of assembling quality, the utility model provides a kind of cylindrical drill universal fixturing, this cylindrical drill universal fixturing is take the part machined surface as locating surface, can guarantee the perpendicularity of part, improve drilling quality.
The technical solution of the utility model is: a kind of cylindrical drill universal fixturing, comprise base plate, base plate top is fixed with bushing plate by left and right column, described base plate middle part is provided with post rod mechanism, the base plate bottom is connected with reservoir, and reservoir inside is provided with clamping piston, and clamping piston top is connected with post rod mechanism, described reservoir bottom is connected with movable tray, and the movable tray bottom connects permanent magnetic chuck by fixed base plate.
Described reservoir is controlled by air-valve.
The utlity model has following beneficial effect: owing to take such scheme, when workpiece is placed on the frock, ejecting by post rod mechanism can be with planar top on the workpiece on bushing plate, realized the machined surface location, the skewness of having avoided the black skin location to cause, make on thread Pilot hole and the taper hole plane verticality better, improve processing, assembling quality.Post rod mechanism has reduced labor strength by reservoir control simultaneously, has improved efficiency.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By figure, shown in Figure 2, a kind of cylindrical drill universal fixturing comprises base plate 1, and both sides, base plate 1 top are fixed with left column 2 and right column 5, and left and right column (2,5) top is fixed with bushing plate 3.Described base plate 1 middle part is provided with post rod mechanism 6, and post rod mechanism 6 bottoms are stretched out by base plate 1 bottom.Base plate 1 bottom is connected with reservoir 8, and reservoir 8 inside are provided with clamping piston 9, and clamping piston 9 tops are connected with post rod mechanism 6, described reservoir 8 is by air-valve 13 controls, it is interior flexible at reservoir 8 to control clamping piston 9 by air-valve 13, thereby post rod mechanism 6 is ejected clamping work pieces.Described reservoir 8 bottoms are connected with movable tray 10, movable tray 10 bottoms are provided with fixed base plate 11, the inner permanent magnetic chucks 12 that connect of fixed base plate 11, absorption that can be by permanent magnetic chuck 12 and loosen to realize movement and the clamping of anchor clamps on fixed base plate 11.
When processing work, first frock is installed on the drilling machine, open air-valve 13 and make post rod mechanism 6 unclamp anchor clamps, be placed on the workpiece locating surface on the frock up again, close air-valve 13 and make post rod mechanism 6 eject clamping work pieces, open permanent magnetic chuck 12 and clamp the top frock, then just can processing work.Workpiece processing, detect complete after, open air-valve 13 and take off workpiece, close again permanent magnetic chuck 12 and unclamp frock.This frock adopts machined surface location, and the skewness of having avoided the black skin location to cause makes on thread Pilot hole and the taper hole plane verticality better, improve processing, assembling quality, post rod mechanism has reduced labor strength by reservoir control simultaneously, has improved efficiency.
Claims (2)
1. cylindrical drill universal fixturing, comprise base plate (1), base plate (1) top is by left and right column (2,5) be fixed with bushing plate (3), it is characterized in that: described base plate (1) middle part is provided with post rod mechanism (6), base plate (1) bottom is connected with reservoir (8), reservoir (8) inside is provided with clamping piston (9), clamping piston (9) top is connected with post rod mechanism (6), described reservoir (8) bottom is connected with movable tray (10), and movable tray (10) bottom connects permanent magnetic chuck (12) by fixed base plate (11).
