Abstract

The utility model relates to a boring machine clamp for a movable arm of an excavator, which comprises a base (1), fixed seats (2), pressing seats (3), a bearing seat (4), a location seat (5) and a limit seat (6) and is characterized in that the fixed seats are fixed at two ends of the base, a plurality of pressing seats are arranged in pairs, each pair of the pressing seats are fixed on two sides of the base, the bearing seat is fixed on the base and below a middle drill hole of the movable arm, two pairs of the pressing seats are fixed on the bearing seat, the fixed seats are fixed at two ends of the base, and the limit seat is fixed on the base. The clamp resolves the problems that lateral sides and an inner hole need processing, location standard is difficult to confirm, and aligning in a process is labor-wasting. Furthermore, after a first product is processed, aligning time for a single product of follow-up products is eliminated.

Description

The excavator swing arm fixture for boring machine

Technical field

The utility model relates to the excavator swing arm fixture for boring machine.

Background technology

By the specification requirement of product design drawing and technology, the depth of parallelism in several groups of holes of product, symmetry are 0.5mm, two hole centre-to-centre spacing 5700mm farthest, and the two side holes axiality is φ 0.03, two side holes both ends of the surface distance is 628mm to the maximum.Theoretically, adopt two-sided boring and milling lathe and special boring mill anchor clamps to get final product.But in design fixture for boring machine process, because the parts of swing arm are spray and panel beating welding part, side and endoporus need processing, and positioning reference is difficult to confirm, add the man-hour centering and take a lot of work.

Summary of the invention

To the problems referred to above, the purpose of the utility model provides a kind of excavator swing arm fixture for boring machine, has solved that side and endoporus need to process, positioning reference is difficult to confirm, add the problem that man-hour, centering was taken a lot of work.

The swing arm fixture for boring machine mainly comprises base (1), holder (2), pressed seat (3), supporting base (4), positioning seat (5), limit base (6), and wherein holder is fixed on the two ends of base; Pressed seat distributes in pairs, and there have to be some right, every pair of both sides that are fixed on base; Supporting base is fixed on the base, is arranged in the below that swing arm is holed; Two pairs of pressed seats are fixed on the supporting base; Positioning seat is fixed on the two ends of base; Limit base is fixed on the base.

Adopted an end to locate with swing arm root seat with positioning seat; With front fork plate location, rotatable pressed seat location is adopted in the location, side to the other end with adjustable support, and the advantage of this locate mode is to utilize adjustable bolt to hold out against location-plate earlier; Adjustable support with homonymy behind the workpiece location is close to workpiece; Use the adjustable support workpiece pressing of opposite side again, and then unclamp the side location-plate, can process behind the centering.

These anchor clamps have solved side and endoporus needs processing, and positioning reference is difficult to confirm, adds the problem that man-hour, centering was taken a lot of work, and after the initial workpiece product processed, the processing subsequent product had saved the single-piece centering time.

Fig. 2 is an excavator swing arm fixture for boring machine vertical view.

The specific embodiment

At first these anchor clamps are installed through T type groove or special-purpose clamp and lathe, during installation, noted guaranteeing the perpendicularity requirement of axial plane and machine tool chief axis in the anchor clamps.After anchor clamps install, excavator swing arm is lifted on the anchor clamps, fore-and-aft direction is with swing arm root seat location, and swing arm front fork direction clamps; Left and right directions directly uses positioning seat location on one side.Pressed seat through both sides clamps swing arm then, can process.These anchor clamps itself have positioner, only need batch machining can be carried out in chuck body and lathe location before the swing arm processing.

Claims

1. the excavator swing arm fixture for boring machine comprises base (1), holder (2), pressed seat (3), supporting base (4), positioning seat (5), limit base (6), it is characterized in that holder is fixed on the two ends of base; Pressed seat distributes in pairs, and there have to be some right, every pair of both sides that are fixed on base; Supporting base is fixed on the base, is arranged in the below that swing arm is holed; Two pairs of pressed seats are fixed on the supporting base; Positioning seat is fixed on the two ends of base; Limit base is fixed on the base.
