Abstract

The utility model relates to a combined type wheel dresser with double diamond-pointed tools, which is mainly composed of the diamond-pointed tools that are breadthwise arranged on a base seat. The wheel dresser is connected to an end bracket of a grinder; two diamond-pointed tools breadthwise pass through two mounting holes of the base seat respectively and are arranged on the base seat separately; firming bolts arranged on the base seat downwards abutting-press and tightly fix the diamond-pointed tools from the upper part of the diamond-pointed tools respectively; the base seat is tightly connected with the end bracket through a screw nail; the upper part of the cross-section of the mounting holes takes the shape of a round and the lower part of the cross-section takes the shape of a V shape, wherein, the diamond-pointed tools breadthwise pass through the mounting holes of the base seat. The combined type wheel dresser has the advantages that a finishing line and a grinding line are parallel naturally without error; the two double diamond-pointed tools adopt different diamond-pointed tools for main finishing and fine finishing in single pass, the depth of cut for finishing can also be adjusted respectively according to the requirements, the finishing quality is good, and the work efficiency is high; the holes for installing the diamond-pointed tools are of an abnormity, and a circle is determined by three points (that are one point and two lines actually), thereby greatly increasing the installation stability of the diamond-pointed tools; the structure is simple, the operation is convenient, and the manufacture cost is low.

Description

Two diamond pen combined type wheel dressers

Technical field

The utility model relates to the wheel dresser of a kind of class grinding machine, particularly two diamond pen combined type wheel dressers.

Background technology

In the field of mechanical grinding processing, we usually can run into workpiece and not reach quality problems such as requirement, surface generation shake line through grinding rear surface roughness.According to one's analysis, cause these quality problems one of the main reasons since emery wheel and wheel dresser instability cause.

Existing wheel dresser is rear-mounted, is installed in the back side of grinding carriage, and single diamond pen structure has independently guide rail and delivering gear.This structure has the some shortcomings part, as:

1, the depth of parallelism of its finishing line and grinding line guarantees to have error by the assembling of trimming device.

2, wheel dresser has only a diamond pen, owing to major in and refine with same diamond pen, effect is undesirable.

3, the hole of installation diamond pen is circular, and diamond pen inserts in the hole and withstood by top screw, forms 2 fixed round labile states up and down.

4, trimming device complex structure, operation inconvenience, cost are also very expensive.

Summary of the invention

The purpose of this utility model is in order to overcome the above-mentioned shortcoming of prior art, provide a kind of simple and convenient, machining accuracy is high, lower-cost wheel dresser.

The technical solution of the utility model is two diamond pen combined type wheel dressers, mainly, diamond pen constitutes by laterally being installed on the pedestal, it is characterized in that this device is connected on the grinding machine tailstock, connect through screw and tailstock are firm, rely on the move left and right of workbench that emery wheel is repaired by pedestal.This wheel dresser is horizontally through two installing holes of pedestal respectively by two diamond pens, be installed separately on pedestal, separately via be contained in fastening bolt on the pedestal from the diamond pen top to pressing down, tighten up diamond pen.The top, installing hole cross section of diamond pen is traditional circle, and the bottom is then V-shaped, and when the downward roof pressure diamond pen of bolt, the diamond pen below forms at 2 with the both sides of V-arrangement and contacts, the realization three-point circle.Two diamond pens are installed side by side, and one another is the refine pen in order to major in pen, and the distance between two nibs is majored in and refine emery wheel in the one-pass process successively greater than the thickness of emery wheel.The refine pen is selected diamond pen preferably for use, and stretches out a refine bite than majoring in pen when mounted more.

The beneficial effects of the utility model are:

1, its finishing line is parallel naturally with the grinding line, does not have error.

2, majored in and refine by different diamond pens respectively in one-pass by two diamond pens, also can adjust the bite of finishing on demand respectively, dressing quality is good, the work efficiency height.

3, the hole of installation diamond pen is an abnormity, realizes three-point circle (reality is 1. two lines), improves the diamond pen mounting stability greatly.

4, structure is very simple, easy to operate, cost is also very cheap.

The specific embodiment

The two diamond pen combined type wheel dressers of the utility model, the contour structures of embodiment and the schematic diagram that is installed in the tailstock rear position thereof are seen accompanying drawing 1.The pedestal 1 of this device is a rectangular block shape, and four installing holes 14 are arranged, and is connected in the back facade of tailstock 2 by four screws 13, after two diamond pens 11 of horizontal cross insert pedestals 1, is held out against downwards respectively by two fastening bolts 12.

The trimming device of seeing from tailstock 2 the place aheads and and emery wheel 3 between relative position referring to accompanying drawing 2.Because this device is installed on the Grinder bench through tailstock 2, the work feed of emery wheel 3 when the feed in when finishing and grinding all is that the motion by Grinder bench realizes, its direction is identical, direction shown in double-head arrow among the figure is so the grinding line that the crushing line contacts with workpiece during with grinding overlaps fully.

The exploded view of the utility model embodiment is referring to accompanying drawing 3.Installing hole 14 is a Long Circle, so screw 13 can move whole device lateral before fastening on a small quantity, gives fastening again so that adjust to the optimum position.

The pedestal 1 of this device has keyway 22 and key 21 guide-localizations with the faying face of tailstock 2, referring to accompanying drawing 4, so device can only laterally move along key, irregular swing can not occur.

The schematic diagram that diamond pen 11 is installed is referring to accompanying drawing 5.Diamond pen 11 is held out against downwards by fastening bolt 12 and reinforces.

3 fastening schematic diagrames were referring to accompanying drawing 6 when diamond pen of the present utility model was installed.Because it is a special shape that the hole 15 of diamond pen 11 is installed, the cross section the first half in hole is circular, and the latter half is a V-arrangement, so when the fastening bolt 12 of top extrudes downwards, form three contact points on the cross-sectional periphery of diamond pen 11 and installing hole 15, be the three-point circle structure, shown in arrow among the figure.The three-point circle structure has improved the diamond pen mounting stability greatly, for the quality that improves crushing very big benefit is arranged.

Fig. 7 is a diamond pen scheme of installation in the prior art.Because the hole 16 of diamond pen 11 is installed on the existing grinding machine be circular, so when fastening bolt 12 extrudes, can only form two contact points on the cross-sectional periphery of diamond pen downwards, is at 2 and decides round unstable structures, shown in arrow among the figure.In addition, a diamond pen only is housed in the prior art, is difficult to guarantee machining accuracy.

Claims

1. two diamond pen combined type wheel dresser, mainly, diamond pen constitutes by laterally being installed on the pedestal, it is characterized in that this device is connected on the grinding machine tailstock, it is horizontally through two installing holes of pedestal respectively by two diamond pens, be installed separately on pedestal, each freely be contained in fastening bolt on the pedestal from diamond pen top downwards roof pressure, tighten up diamond pen; Pedestal connects through screw and tailstock are firm.
