Abstract

The utility model provides an angle iron lathe clamp. When the angle iron lathe clamp is used for machining a workpiece, firstly the workpiece has a right position relative to a cutter and a lathe. When the workpiece is clamped on a working platform of the lathe directly, generally lines are drawn on the surface of the workpiece according to pattern requirements, size and position of a machining surface are drawn, and clamping is performed after alignment through an embossing stylus or a dialgage. No special equipment is needed in the method, however efficiency is low, and the method is generally used for one-piece or small-scale production. The angle iron lathe clamp comprises a transition plate (1) which is connected with a clamping body (2), the claming body is connected with a balancing block (3), a movable diamonds-shaped pin (4), a bolt A (5) and a bolt B (6) are installed on the clamping body, a pressing plate (7) is installed on the bolt A and the bolt B, and the pressing plate is connected with a V-shaped swinging block (8). The angle iron lathe clamp is used for machining and positioning of the workpiece.

Description

Angle bar formula turning attachment
Technical field:
The utility model relates to a kind of angle bar formula turning attachment.
Background technology:
Fixture is a kind of technological equipment that the machine-building factory uses, and is divided into jig, weld jig, assembling jig and inspection jig etc.The technological equipment that is used for clamping workpiece on various Metal Cutting Machine Tools claims jig, as the parallel jaw that uses on the three-jaw self-centering chuck that uses on lathe, milling machine etc.
When workpiece is carried out machining, in order to guarantee processing request, at first to make workpiece with respect to cutter and lathe, correct position be arranged, and make this position in process not the impact because of external force change.For this reason, before carrying out machining, first that clamping workpiece is good.The clamping method of workpiece has two kinds: a kind of is that the direct clamping of workpiece is on the workbench of lathe; Another kind is that clamping workpiece is on fixture.Adopt the direct clamping of first method workpiece during clamping workpiece, generally will first rule at surface of the work by pattern requirements on the workbench of lathe, size and the position of marking finished surface, during clamping with clamping again after scriber or dial gauge centering.This method need not equipment special, but efficient is low, generally is used for single-piece and small serial production.When batch is larger, large multiplex fixture clamping workpiece.
Summary of the invention:
The purpose of this utility model is to provide a kind of angle bar formula turning attachment.
Above-mentioned purpose realizes by following technical scheme:
A kind of angle bar formula turning attachment, its composition comprises: transition disc, described transition disc is connected with clamp body, described clamp body is connected with balance weight, movable rhombus pin, bolt A, bolt B are installed on described clamp body, pressing plate is arranged on described bolt A, described bolt B, and described pressing plate is connected with the swing vee-block.
Described angle bar formula turning attachment is equipped with fixed support plate, active supporting plate on described clamp body, on described fixed support plate, cover plate is installed.
Described angle bar formula turning attachment, described pressing plate is connected by connecting rod with described swing vee-block.
Described angle bar formula turning attachment, described balance weight is connected by bolt C with described clamp body.
Beneficial effect:
1. the utility model is used for processing housing, bearing, the face of cylinder on joint parts and end face.Because part shape is more complicated, be difficult to clamping on universal chuck, thereby must the design specialized fixture.When the main positioning datum of workpiece to be machined is the plane, when the axis of machined surface keeps certain position relationship (parallel or Cheng Ding angle) to main position datum level, correspondingly the plane positioning part on fixture be located at parallel with the lathe spindle axis or angled position on.Can stably guarantee the machining accuracy of workpiece, during with the fixture clamping workpiece, workpiece is guaranteed by fixture with respect to the positional precision of cutter and lathe, is not subjected to the impact of workman's technical merit, and the machining accuracy of a collection of workpiece is reached unanimity.
2. the utility model can be raised labour productivity, and uses the fixture clamping workpiece easily and fast, and workpiece does not need the centering of ruling, and can reduce unproductive time significantly, raises labour productivity; Workpiece has improved the rigidity of workpiece after clamping in fixture, therefore can strengthen cutting data, raises labour productivity; Can use many, the fixture of multistation clamping workpiece, and can use efficient clamp mechanism, further raise labour productivity.Can enlarge the scope of application of lathe.
