Description
Technical field
The utility model belongs to the Machining Technology field, relates to a kind of fixture, is specifically related to a kind of universal drilling jig.
Background technology
The plate-like such as flange, end cap class part is common part in machining industry, in the preparation equipment that certain company produces, the application of the plate-like class parts such as flange, end cap is also very many, annual flange, the end cover part material of producing of the said firm mostly is steel part or foundry goods class, and the various and shape of quantity and specification are varied.This type of flange, end cover part mostly are and expose part, require good looking appearance, have interchangeability when require using simultaneously, namely require the bolt hole position of each part to want accurately.
Must be through crossed process before traditional processing method boring, because plate-like class part all has centre bore, bad alignment point, so work very complex of ruling, if number of spare parts is few and the need renewal part, need frequent line, change fixture etc., greatly increased labor intensity, having reduced production efficiency and machining accuracy can not effectively be guaranteed.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, a kind of universal drilling jig is provided, it is reasonable in design, simple in structure, convenient and practical, effectively reduce labor intensity, enhance productivity, improve crudy and the positional precision of boring, product interchangeability is good, is easy to assembling.
for achieving the above object, the technical solution adopted in the utility model is: a kind of universal drilling jig, comprise that the top outer circumference surface is equipped with the base of dial, it is characterized in that: described base inner rotation is equipped with pedestal, be provided with bearing between described base and described pedestal, be provided with the clamping device for fastening location between described pedestal and base, described pedestal upside is installed with backing plate, described backing plate inside is equipped be used to the scroll chuck that adds clamping of workpieces, described workpiece upside is provided with pressing plate, described pressing plate is arranged on the workpiece upside by the screw rod that an end is fixed in pedestal middle part.
Above-mentioned universal drilling jig is characterized in that: described pedestal bottom along the circumferential direction evenly is provided with the graduation mark that matches with base high scale dish.
Above-mentioned universal drilling jig is characterized in that: described bearing is single direction thrust ball bearing.
Above-mentioned universal drilling jig is characterized in that: described clamping device is the handle type self-locking jig.
The utility model compared with prior art has the following advantages:
(1) this universal drilling jig design is very reasonable, simple in structure, and operating personnel only need workpiece is arranged on this fixture, handle drilling machine and are the cocoa complete operation, and are convenient and practical.
(2) this universal drilling jig is compared with original fixture and has been reduced line and tool setting operation, effectively reduces labor intensity, improves enterprises production efficiency.
(3) this universal drilling jig has improved crudy and the positional precision of boring, and product interchangeability is good, is very easy to during assembling.
Below by drawings and Examples, the utility model is described in further detail.

The specific embodiment
A kind of universal drilling jig as shown in Figure 1, comprise that the top outer circumference surface is equipped with the base 1 of dial, described base 1 inner rotation is equipped with pedestal 3, described pedestal 3 bottoms along the circumferential direction evenly are provided with 360 ° of graduation marks that match with base 1 high scale dish, dial on graduation mark and base 1 is used in conjunction with, be the accurately foundation of rotation of workpiece 6, guarantee the degree of accuracy of each bore position.Be provided with bearing 2 between described base 1 and described pedestal 3, described bearing 2 is single direction thrust ball bearing, and single direction thrust ball bearing can make this fixture bear axial force.Be provided with the clamping device 8 for fastening location between described pedestal 3 and base 1, described clamping device 8 is the handle type self-locking jig, the handle type self-locking jig can be realized the fastening and location between pedestal 3 and base 1 effectively, guarantee that pedestal 3 does not rotate in process, this is accurately to hole and pinpoint premise.Described pedestal 3 upsides are installed with backing plate 7, and described backing plate 7 inside are equipped be used to the scroll chuck 4 that adds clamping of workpieces 6, and described workpiece 6 upsides are provided with pressing plate 5, and described pressing plate 5 is arranged on workpiece 6 upsides by the screw rod 9 that an end is fixed in pedestal 3 middle parts.
The course of work of the universal drilling jig of the utility model is: base 1 that at first will this universal drilling jig is fixed by bolts on workbench 10, utilizes clamping device 8 that pedestal 3 and base 1 is closely fixing.Then with scroll chuck 4 with workpiece 6 to clamp, selects suitable backing plate 7, and backing plate 7 use holding screws is connected on pedestal 3 reliably, pressing plate 5 is installed, and is tightened the nut that screw rod 9 upper ends are used for clamping platen 5, workpiece 6 location clampings are completed.Record the pedestal circumference number of degrees shown in base 1 high scale dish, then according to the position in workpiece 6 first holes, suitably regulate the relative position of drill press spindle and fixture, make drill bit first center, position, hole, and locking drill press spindle and fixture, then start drilling machine and begin boring.After processing a hole, unclamp clamping device 8, and turning of work piece 6 is to proper angle, more fastening clamping device 8 locking pedestals 3, the processing in other hole completed smoothly.
The above; it is only preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment does, all still belong in the protection domain of technical solutions of the utility model.
