Description

For the high accuracy burr removal tool of engine crankshaft

Technical field

The utility model is related to machine tool technical field, more particularly to a kind of high accuracy burr for engine crankshaft Removal tool.

Background technology

At present, during the manufacturing, bent axle product that can usually hold by after machining, left at grade both sides fan plate Many burrs, if dealing with improperly, can cause engine noise in operation process big after being fitted into engine, reduced lifetime, sternly Can cause engine Bearing score when weight, directly scrap.

In the prior art, being typically with the unilateral method deburred is carried out, inefficiency, while being easy to scratch axle Neck is cylindrical, influences cylindrical precision, so as to cause that requirement can not be met during assembling, the influence engine overall life-span.On the other hand, Using the unilateral method deburred, due to the contact conditions in bad control and fan plate, it is easy to cause burr bent axle incomplete, And then have to arrange special messenger to be done over again, production efficiency is had a strong impact on, increase company's processing cost.

Utility model content

The utility model aims to provide a kind of high accuracy burr removal tool for engine crankshaft, solves well Above mentioned problem, its simple structure, it is easy to manufacture is easy to operate, can effectively solve the problem that burr removal not exclusively, inefficiency, Easily scratch crankshaft journal it is cylindrical the problems such as, while effectively raise operating efficiency, it is to avoid do over again, saved the working time, Reduce processing cost.

The technical solution of the utility model is a kind of high accuracy burr removal tool for engine crankshaft, including handle Hand, described handle one end is symmetrically arranged with a pair of grinding heads, and handle head end of closely polishing is rotatablely equipped with bearing, the bearing Axis it is vertical with handle plane.

Further, the grinding head is fixedly connected by rivet with handle.

Further, the bearing is arranged in handle axis.

The beneficial effects of the utility model are：

1. the utility model holds handle by operating personnel, and grinding head is placed on fan plate, and bearing is smooth with axle journal to be connect Touch, the continuous pull handle back and forth of operating personnel, while bent axle is constantly rotated, by rotation repeatedly and pull handle, you can The burr that removal fan plate both sides leave by machining completely；The utility model is easily fabricated, easy to operate, can effectively solve the problem that hair The problems such as thorn removes incomplete, inefficiency, easily scuffing crankshaft journal is cylindrical, while effectively raising operating efficiency, keeps away Exempt to do over again, saved the working time, reduced processing cost；

2. grinding head is fixedly connected by rivet with handle, it is easy to dismounting and replacing grinding head, improves the efficiency of operation.

In figure：1. handle, 2. rivet, 3. grinding head, 4. bearing, 5. fans plate.

Specific embodiment

In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing, to this reality It is further elaborated with new.

As shown in Figure 1 to Figure 2, the utility model provides a kind of high accuracy burr for engine crankshaft and removes work Tool, including handle 1, one end of the handle 1 are symmetrically arranged with a pair of grinding heads 3, and the nearly end of grinding head 3 of the handle 1 rotates installs There is bearing 4, the axis of the bearing 4 is vertical with the plane of handle 1.

Grinding head 3 is fixedly connected by rivet 2 with handle 1.Bearing 4 is arranged on the axis of handle 1.

The utility model holds handle 1 by operating personnel, and grinding head 3 is placed on fan plate 5, and bearing 4 is smoothed with axle journal Contact, continuous pull handle 1 back and forth of operating personnel, while bent axle is constantly rotated, by rotation repeatedly and pull handle 1, It is completely removed the burr that the fan both sides of plate 5 leave by machining；The utility model is easily fabricated, easy to operate, can be effective The problems such as solving incomplete burr removal, inefficiency, cylindrical easy scuffing crankshaft journal, while effectively raising work effect Rate, it is to avoid do over again, has saved the working time, reduces processing cost；Grinding head 3 is fixedly connected by rivet 2 with handle 1, easily In dismantling and changing grinding head 3, the efficiency of operation is improve.

Certainly, the utility model can also have other various embodiments, spiritual and its essence without departing substantially from the utility model In the case of, those of ordinary skill in the art can make various corresponding changes and deformation, but these phases according to the utility model The change and deformation answered should all belong to the scope of the claims appended by the utility model.
