Abstract
The utility model provides a correction wheel, belongs to the field of a mechanical technology, and solves the problem that an existing concentric correction wheel is long in correction time and bad in correction effect. The correction wheel is arranged between an upper grinding disc and a lower grinding disc, an inner gear ring is arranged on the outer edge of the lower grinding disc, and a sun wheel is arranged in the middle of the lower grinding disc. The correction wheel comprises a disc-shaped body, the middle body of the body is provided with a round through hole, the round through hole and the body are eccentrically arranged, the sun wheel penetrates the round through hole, and the outer edge of the body is provided with an outer gear ring matched up with the inner gear ring. According to the correction wheel, the flatness of the grinding discs can be improved, the correction time can be shortened, and the yield of down-stream products can be improved.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of wheel of revising, particularly a kind of correction wheel that grinder dish is carried out to shaping.
Background technology
Surface grinding is the Surface Machining to material piece such as quartz, silicon, glass, potteries, makes it reach the method for certain thickness, fineness and flatness.Abrasive disk is common film forming system, and the flatness of the ground flat of abrasive disk will directly affect precision and the quality of surface and other processing index.In order to guarantee the flatness of abrasive disc, all adopt the mode of grind and revise wheel to carry out grind and revise both at home and abroad.Its concrete mode is, in the periphery of abrasive disk, the ring gear not contacting is with it set, the sun gear that the setting of abrasive disk central hole location does not contact with it, and sun gear, with external tooth, engages 3-4 and revises wheel between ring gear and sun gear.Although which can slow down the distortion of abrasive disc, but the diameter of revising wheel is less than the radius of abrasive disk, correction effect is undesirable, after using a period of time there is umbrella, taper distortion in abrasive disk, the method that need to adopt other is carried out equating abrasive disk again as equipment such as surface grinding machines, expense is high, it is loaded down with trivial details to operate, and also had a strong impact on the utilization rate of abrasive disk.
For this reason, people explore through long-term, have proposed various solutions, and some has also applied for patent.For example, Chinese patent discloses a kind of truing wheel for grinding discs of grinder [application publication number is: CN101708594 A], it is made up of drive and shaping wheel two parts, drive is engaged between external toothing and shaping wheel, thereby guarantee that shaping wheel moves in a circle along ring gear, external toothing connects grinder central shaft, and shaping is taken turns between lower abrasive disk and top lap.But this structure is long to the correction time of abrasive disk, the flatness of abrasive disk can not get effective raising, and is provided with drive, complex structure.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed the correction wheel that a kind of reasonable in design, correction effect are good.
The purpose of this utility model can realize by following technical proposal:
This correction wheel, be located between top lap and lower abrasive disk, the outer of lower abrasive disk is provided with ring gear, the middle part of lower abrasive disk is provided with sun gear, it is characterized in that, this correction wheel comprises body in the form of annular discs, and the middle part of described body has the manhole with body eccentric setting, sun gear is located in this manhole, and the outer of described body has the external toothing coordinating with ring gear.
In above-mentioned correction wheel, the diameter of described manhole is greater than the diameter of sun gear.Revise between wheel and sun gear and have gap, the convenient wheel of revising rotates around sun gear.
In above-mentioned correction wheel, the 1/3-1/2 that the area of described manhole is this bulk area.
In above-mentioned correction wheel, the area of described manhole is this bulk area 1/2.
Compared with prior art, this correction wheel has the following advantages:
By by manhole and body eccentric setting, thereby realize body and sun gear eccentric setting, increase centrifugal force, improve abrasive disc degree, improve 0.01mm than revising with one heart the revised ground flat degree of wheel, (the every raising of the flatness 0.005mm of abrasive disk, the qualification rate of downstream product crystal just improves 5%) is equivalent to improve the qualification rate of downstream product crystal 10%, but also shortened the correction time.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of preferred embodiment of providing of the utility model.
Fig. 2 is the cutaway view of a kind of preferred embodiment of providing of the utility model.
In figure, 1, body; 2, manhole; 3, external toothing.
The specific embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
This correction wheel, be located between top lap and lower abrasive disk, the outer of lower abrasive disk is provided with ring gear, the middle part of lower abrasive disk is provided with sun gear, as depicted in figs. 1 and 2, this correction wheel comprises that body in the form of annular discs 1, the middle part of body 1 have and the manhole 2 of body 1 eccentric setting, sun gear is located in this manhole 2, and the outer of body 1 has the external toothing 3 coordinating with ring gear.
In the present embodiment, the diameter of manhole 2 is greater than the diameter of sun gear, and the area of manhole 2 is the 1/3-1/2 of body 1 area, revises between wheel and sun gear and has gap, and the convenient wheel of revising rotates around sun gear.
Concrete, the area of manhole 2 is 1/2 of body 1 area.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
