Abstract
The utility model discloses a mold for drilling a wheel core support of an excavator. The mold comprises a seat plate (1), wherein the seat plate (1) is provided with a support pipe column (2); the top of the support pipe column (2) is provided with a circular positioning plate (3); a pressure plate (4) is arranged above the positioning plate (3); a cushion block (5) is arranged between the positioning plate (3) and the pressure plate (4); and a threaded stud (6) is connected between the positioning plate (3) and the pressure plate (4). A tool mold which is convenient to position is adopted, and necessary drilling can be completed by clamping a part at one time, so that processing accuracy is easy to ensure, and the part processing accuracy can be ensured for a long time in future use processes; and moreover, the workload of operating personnel is lowered, the mold is convenient, rapid and safe for using, and the working efficiency is increased greatly. The mold has a simple structure and a good use effect, and is easy to implement.
Description
Technical field
The utility model relates to a kind of frock, particularly a kind of mold that is used for excavator core wheel supporting boring processing.
Background technology
The core wheel supporting is an important component in the excavator rear axle housing assembly, and it is connected to integral body by the soket head cap screw of 20 M16 with brake support and rear axle housing.Because production equipment is limited, requirement on machining accuracy is high,, mainly be to adopt the mode of joining brill to hole for guaranteeing machining accuracy.But, existing, processes rear axle housing because of adopting on the horizontal Machining centers, and machining accuracy improves greatly, and integrated multi-step process is in a clamping revolution processing, comprises the previous driller's preface of joining.Not only do not simplify manufacturing procedure if still keep the brill of joining between the supporting of brake support and core wheel this moment, directly increased workload on the contrary, makes production efficiency low, time-consuming, effort, and do not have economic benefit.In order to address this problem, just need improve frock, a kind ofly can reduce clamping times, easy for installation and can improve the mold of positioning accuracy so lack now.
Summary of the invention
The utility model technical problem to be solved is: a kind of mold that is used for excavator core wheel supporting boring processing is provided; It can accomplish the boring processing of core wheel supporting in a clamping; And it is simple to operation; High efficiency can satisfy the required precision of processing simultaneously, to overcome the deficiency of prior art.
Being achieved in that of the utility model is used for the mold that excavator core wheel supporting boring is processed; Comprise seat; On seat, be provided with the supporting tubing string, be provided with the location-plate of annular at the top of supporting tubing string, above location-plate, be provided with pressing plate; Between location-plate and pressing plate, be provided with cushion block, between location-plate and pressing plate, be connected with stud.
On location-plate, be provided with the arc gap of two symmetries; And being provided with round boss in the bottom of location-plate, the external diameter of round boss is corresponding with the internal diameter of being in the charge of post.Arc gap on the location-plate can the handled easily personnel conveniently put into and take out the core wheel supporting before and after drilling, operating personnel can directly up carry from the disk place that arc gap is held part with hand after having bored a core wheel supporting, thereby part is taken out; Conversely, operating personnel also can hold the disk diameter place of part, and arc gap place on the hand aligned plate is put into part.Like this, not only part is convenient, fast about the operating personnel, and safety coefficient is high, is difficult for weighing wounded finger, has effectively avoided the generation of industrial accident; The round boss of the bottom of location-plate has made things convenient for the installing and locating of location-plate, has improved positioning accuracy.
On seat, be provided with seam, the internal diameter of seam is corresponding with the external diameter of supporting tubing string.Seam on the seat has made things convenient for the location of seat and support column column diameter.
On seat, be provided with the fixing port of the circular arc of two symmetries.Make seat can be convenient, be fixed by bolts on the platen quickly.
Be provided with installing port in the pressing plate inboard.Both conveniently compressed like this, and can make the assembling between each part compact more, reasonable again.
Owing to adopted technique scheme; Compared with prior art; The utility model adopts the fixture clamping fixture of a convenient location; It only need carry out a clamping with part just can accomplish necessary boring processing, and the precision that so easy assurance is processed can both guarantee the precision of its processing parts for a long time in the use afterwards; And reduced operating personnel's workload, easy to use, quick, and safety, improved operating efficiency greatly.The utility model is simple in structure, implements easily, and result of use is good.
