Abstract
The utility model provides a medium-sized excavator crawler chassis processing device, which is characterized in that the processing device comprises a workbench, a fixed support is arranged on one side of the workbench, a slide track is arranged on the other side of the workbench, a movable support is arranged on the slide track, both the fixed support and the movable support are provided with positioning V-shaped blocks, an adjustable support is arranged at a position on the workbench between the fixed support and the movable support, calibrating supports are arranged at positions on the workbench and on the two sides of the fixed support, and regulating supports are arranged at positions on the workbench and on the two sides of the movable support. The processing device has the advantages of convenient and fast operation, easy-guaranteed product quality and capability of reducing labor intensity and increasing working efficiency.
Description
Technical field
The utility model relates to a kind of medium-sized excavator crawler belt base processing unit (plant), belongs to the excavator technical field.
Background technology
In the excavator manufacture process, the crawler belt base is a vitals that is related to the complete machine walking stability, and it is by a left side, and right support body and base three parts are welded.Base then is the backbone in these three parts, and its mechanical processing technique is to guarantee it is the key of crawler belt base group to quality, and the main contents of machining have:
1. installed surface, i.e. bracing ring upper surface are supported in revolution;
2. central swivel coupling installed surface.
There is important related size to be with these two processing contents, the symmetric relation of left and right crawler belt beam and base interface and the base centre of gyration, and the bracing ring top surface plane is to the relative size of left and right crawler belt beam and base interface.Because base machine adding method in the past is that because the base group adds the benchmark disunity to benchmark and machine, so the machine added-time need be proofreaied and correct the bracing ring upper surface, correction time is long with base lower cover location.And the quality instability, the destabilizing factor of the base of processing back welding is too many, the machining set-up of highly effective satisfies production so need more.
Summary of the invention
The purpose of this utility model provides a kind of device of the medium-sized excavator crawler belt of the processing base of can be fast, need not to proofread.
In order to achieve the above object, the technical solution of the utility model provides a kind of medium-sized excavator crawler belt base processing unit (plant), it is characterized in that, comprise workbench, the worktable upper surface left side is provided with slide rail, slide rail is provided with movable bearing support, the worktable upper surface right side is provided with hold-down support, the slide rail left side is provided with beam support, beam support is provided with beam, beam is provided with bolt, the end of bolt all is provided with the location vee-block against movable bearing support on hold-down support and the movable bearing support, the position on the workbench between hold-down support and movable bearing support is provided with adjustable supports, the position that is positioned at both sides, hold-down support front and back on the workbench is provided with the verification bearing, and the position that is positioned at both sides, movable bearing support front and back on the workbench is provided with the adjustment bearing.
The utility model has the advantages that:
1, clamping screw is few, and is easy to operate simple and direct, reduces labour intensity, improved operating efficiency;
The benchmark of 2, machined preface respectively with the unifying datum of upper track parts group to welding and following road assembly welding, targeting scheme is reasonable, it is even that machine adds surplus, it is little that clamping workpiece good rigidly, machine add vibration, the quality of product is more prone to assurance.
3, save the proof-reading (proofreading and correct the depth of parallelism of bracing ring upper surface and workbench or frock backplate surface) of wasting the clamping time most in the whole process, shortened the process-cycle of these parts greatly, improved production efficiency.
Description of drawings
Fig. 1 is medium-sized excavator crawler belt base processing unit (plant) front view;
Fig. 2 is medium-sized excavator crawler belt base processing unit (plant) vertical view;
Fig. 3 is medium-sized excavator crawler belt base processing unit (plant) application state figure.
The specific embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 1, be medium-sized excavator crawler belt base processing unit (plant) front view, Fig. 2 is its vertical view, and described medium-sized excavator crawler belt base processing unit (plant) is made up of beam support 1, beam 2, movable bearing support 3, adjustable supports 5, hold-down support 6, slide rail 7, adjustment bearing 8 and verification bearing 9.
As shown in Figure 3, be medium-sized excavator crawler belt base processing unit (plant) application state figure, the using method of this device is:
1, at first, movable bearing support 3 is drawn back, again base 9 is hung in this device, base 9 bracing ring lower surfaces lean against the extension at hold-down support 6 tops, and base 9 bracing ring cylindricals are close to the location vee-block at hold-down support 6 tops;
2, then, shift movable bearing support 3 onto clamped position, base 9 bracing ring lower surfaces lean against the extension at movable bearing support 3 tops, and cylindrical then is close to the location vee-block at movable bearing support 3 tops;
3, by the locking of the bolt on the beam 2 movable bearing support 3.
4, adjust bearing 8, make the gap between workpiece and the verification bearing 9 even.
5, the pinching screw on hold-down support 6 and the movable bearing support 3 is locked.
6, last, adjustable supports 5 is adjusted to is adjacent to workpiece lower plate surface.
7, machine after, use the operating sequence opposite that workpiece is hung out frock with mounting means.
