Detailed description of the invention
This application provides a kind of grinding rod, achieve and a kind of grinding rod being convenient to change is provided.Present invention also provides a kind of lathe comprising above-mentioned grinding rod.
Below in conjunction with the accompanying drawing in the embodiment of the present application, carry out clear, complete description to the technical scheme in the embodiment of the present application, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments.Based on the embodiment of the application, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the application's protection.
The front view of the grinding rod that Fig. 1 provides for the application; The side view of the grinding rod that Fig. 2 provides for the application.
A kind of grinding rod that the application provides, comprise for the body part 1 be arranged on lathe saddle and the grinding component for grinding work-piece be arranged on body part 1, grinding component is dismountable to be fixed on body part 1.Body part 1 plays the effect of support, and grinding component is provided with abrasive material, for grinding workpiece.Be arranged on body part 1 because grinding component is dismountable, like this, when after grinding component wearing and tearing, need not change whole grinding rod, and only need to change grinding component, such structure is convenient for changing.
In the application one specific embodiment, the head of body part 1 is provided with stud 3, and the afterbody of grinding component is provided with the first screw 4, the axis coaxle of screw and grinding component, and body part 1 is connected by stud 3 and the first screw 4 with grinding component.Concrete, grinding component can adopt with body part 1 and be threaded.Concrete is designed to, and body part 1 is column, and its cross section is rectangle, there is a thinner stud 3 its front end, and grinding component entirety is in column, and its afterbody has first screw 4, affixed with coordinating of the first screw 4 by stud 3, realize removably connecting of body part 1 and grinding component.
In the application one specific embodiment, outer wall grinding component being positioned at the first screw 4 is provided with through the second screw to its inwall, the front end tight abutment of the first screw 5, first screw that ecto-entad screws in is provided with in the surface of stud 3 in second screw.In the processing of this area, generally processed workpiece, for machining piston pin-and-hole, piston pin hole rotates, and grinding rod does not rotate, in such process, piston can give grinding rod rotating torque, and aforementioned stud 3 and the first screw 4 are threaded, if the effect that rotating torque plays makes it tighten, there will not be fault like this, but the unavoidable effect that sometimes this rotating torque plays aforementioned threads is connected loosen, and can cause being threaded like this untiing, body part 1 and grinding component are thrown off, and cause fault.In order to avoid this hidden danger, optimize structure, can increase by the first screw 5 further.First screw 5 enters in it by the side direction of the first screw 4, is namely entered by the second screw, and the side of stud 3 is withstood in its front end, plays the effect spacing to it, prevents it from being thrown off by rotating torque uncoiling.Preferred scheme is, is arranged side by side two the first screws 5 along axle 2 axis direction, improves fixing firmness.
In the application one specific embodiment, the ox-hide abrasive material 7 that grinding component comprises axle 2 and is wrapped in axle 2.Owing to selecting ox-hide abrasive material 7 to be wrapped in the axle 2 of metal, original wool felt is replaced to be wrapped on wooden stick, the anti-wear performance of the grinding component greatly improved.
In the application one specific embodiment, the upper surface that axle 2 wraps up the axle portion of ox-hide abrasive material 7 is plane, and lower surface is circular arc outstanding downwards.Axle 2 front end is axle portion, and rear end is the part arranging the first screw 4.Axle portion is used for arranging ox-hide abrasive material.Because its cross section adopts the structure of upper straight, bottom circular arc, namely cross section is one and is intercepted the circle of a upper end part.This shape conveniently comprises abrasive material, because its top is flat, conveniently arranges fixed connecting piece, and bottom is outwardly arc, can better contact with to be ground of workpiece.
In the application one specific embodiment, ox-hide abrasive material 7 thickness is 4 millimeters to 5 millimeters.Obtaining above-mentioned data through practice, is preferred scheme.
In the application one specific embodiment, axle 2 upper surface is provided with and ranked third screw along one of its axial setting, the crossover position that ox-hide abrasive material 7 wraps up is arranged at directly over the 3rd screw, also comprise the second screw 6, second screw 6 to be fixed in the 3rd screw through the crossover position of ox-hide abrasive material 7.Concrete, ox-hide abrasive material 7 is fixed in axle 2 with the second screw 6, and the crossover position that ox-hide abrasive material 7 wraps up, just in time at the upper surface of axle 2, is pegged by the second screw 6.
The grinding rod abrasive power that the application provides is adjustable, grinding effect good, labour intensity is low, handling safety, and structure is split-type structural, and structure is simple, light, very easily manufacture.
Based on the grinding rod provided in above-described embodiment, present invention also provides a kind of lathe, the grinding rod comprising lathe spindle, lathe saddle and be arranged on described lathe saddle, grinding rod is the grinding rod of above-mentioned any embodiment.
Because this lathe have employed the grinding rod of above-described embodiment, so the beneficial effect that this lathe is brought by this grinding rod please refer to above-described embodiment.
In this description, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
