Abstract

The utility model discloses a new spherical wrapping machinery pot grinding device to the society, which is suitable for the smooth finish grinding machining of the surface of a molded iron pot. The utility model uses the method of rotating a machinery clamping device and the iron pot together, and moreover, the utility model uses multiple wheel grinding heads to grind. Patterns on the inner surface of the ground iron pot are even and dense, smooth, clean and beautiful. Noise is reduced greatly when the iron pot rotates; the roughness of the inner surface of the iron pot and the work efficiency are both improved.

Description

Spherical envelope machinery mill Pot devices

The utility model relates to a kind of improved mill Pot devices, and particularly a kind of spherical envelope machinery mill Pot devices is applicable to the polishing grinding to casting iron pan inner surface.

Existing mechanical mill Pot devices is made up of iron pan [10], emery wheel bistrique [11], pinch roller [12] and iron pan rotating mechanism [13], and its mounting and clamping system is that the wheel by three troughs of belt is pressed on the iron pan edge of rotation.Bistrique is an annulus emery wheel, and when grinding, pinch roller does not rotate with iron pan, only makes spinning motion under iron pan drives.Rotating mechanism drives iron pan and rotates, and bistrique contacts with the iron pan inner surface by its deadweight, and arcuate movement is made in bistrique rotation on one side on one side in pot.Because iron pan generally all is a cast member, pot edge and inner surface be irregularity mostly, and the installation way of this mill Pot devices is when the grinding iron pan, because the relative motion of pinch roller and iron pan edge, cause very big noise, the person is had very big infringement, carry out grinding because bistrique is conducted oneself with dignity by it and iron pan contacts again, it is very unstable to work, as run into hard raised points bistrique and can be upspring automatically, do not reach whole bright and clean effect, and the grinding time is long, the pot inside surface roughness is low.

The purpose of this utility model is that a kind of improved mill Pot devices will be provided, and it not only can reduce noise significantly, alleviates the harm to human body, and can also make iron pan inner surface Even Grinding, reaches bright and clean purpose attractive in appearance.

The utility model is finished as follows.Spherical envelope machinery mill Pot devices is by the bistrique that several little emery wheels are housed [1], pressing plate [3], spring [7] and the plate washer [4] and the rotating mechanism [9] of pressing plate disengaging pot edge are formed.Bistrique [1] is contained on the disk by several little emery wheels to be formed, bistrique [1] is horizontal state with iron pan [2], drive by transmission system [9], bistrique [1] rotates when work on one side, the inner surface of the whole iron pan in one edge is done a fixing arc swing motion, so that bistrique arrives the edge of iron pan.Iron pan [2] is driven by transmission system [9] and rotates, iron pan [2] rotatablely move and two relative motions of bistrique [1] under, multiple spot contact grinding has realized the spherical envelope grinding process to iron pan, the iron pan inner surface decorative pattern even compact that grinding goes out is bright and clean attractive in appearance.Because grinding is that mechanically actuated is carried out, stock removal is even feeding in iron pan, can not stay the phenomenon that mill does not fall raised points.In grinding process, whole mechanical clamping device rotates with pot.For being unlikely, bistrique [1] is ground on the pressing plate [3], be provided with baffle plate [4], baffle plate [4] is fixed on the support, there are two of A-A face and B-B face to have the chute that circular arc imports the angle in baffle plate [4] rising, and be provided with bearing [5] and bearing [6] in the afterbody and the top of pressing plate [3], so that can pass through these two chutes smoothly at rotary course center platen [3].The A-A face runner position of baffle plate [4] is lower than the position of pressing plate [3], the chute of B-B face is far away than the bearing [6] on the pressing plate [3] from the iron pan center line, the middle part of pressing plate [3] has a circular slideway, the nut of fixture [8] is suspended on the pressing plate [3], when pressing plate [3] rotates into plate washer [4] with iron pan [2], the A-A face makes pressing plate [3] lift the disengaging iron pan, the B-B face pulls back pressing plate [3], make pressing plate [3] break away from the pot edge, the arc track that bistrique [1] is walked is to carry out between two plate washers [4].Therefore the bistrique mill is less than pressing plate [3].After pressing plate [3] broke away from from plate washer [4], under the effect of spring force, pressing plate was pressed on pot edge again.Owing to adopt the form of this mechanical grip iron pan, the noise during the iron pan rotation reduces greatly.

Concrete structure of the present utility model is described by following accompanying drawing and embodiment provides.

Figure one is the work sheet of existing mill Pot devices;

Figure two is bistrique assembly drawings of the present utility model;

Figure three is work sheets of the present utility model;

Figure four is side views of the present utility model;

Figure five is A-A profiles of the present utility model;

Figure six is B-B profiles of the present utility model;

With reference to figure two, several little emery wheels are housed on the disk of bistrique [1], when bistrique rotates, can form the annulus of multiple spot contact.

With reference to figure three and figure four, physical location figure when figure three is the work of mill Pot devices, emery wheel [1] contacts with iron pan [2], inner surface along iron pan [2] is done spheric motion on one side, dashed trace moving linearly between the plate washer [4] among the one edge figure four, pressing plate [3] is fixed on the base plate by fixture [8], the nut of fixture [8] is suspended on the pressing plate [3], the latter half of circular hole that has at pressing plate, spring [7] is fixed in the circular hole, and the other end of spring [7] is fixed on the base plate, and the afterbody of pressing plate [3] is equipped with bearing [5], the latter half of bearing [6] that is equipped with, plate washer [4] is fixed.Design has two to have the chute that circular arc imports the angle on it.When pressing plate [3] entered plate washer [4], pressing plate had been pressed the back and has been withdrawed from, and dotted portion is the state of pressing plate when getting up among the figure.

The utility model noise in force reduces greatly, and the iron pan inside surface roughness can reach more than 3.2, convenient mounting and clamping during use, and the grinding accuracy height, because the grinding of many wheels, operating efficiency improves greatly.
