The machining device comprises a bottom plate and is structurally characterized in that a positioning key is arranged at the bottom of the bottom plate; a supporting pipe and a side plate are arranged between the bottom plate and an upper plate; a hook groove is formed at the bottom of the outer side surface of the side plate; top threads are arranged on both sides of the side plate and both sides of the upper plate respectively; a pressing plate is arranged at the upper part of a bolt in the supporting pipe; a positioning nut is arranged on a bolt at the upper part of the pressing plate; and a bolt between the pressing plate and the upper plate is provided with a nut.
Description
Technical field
The utility model relates to the processing unit (plant) with the tooth crushing shell.
Background technology
Double-geared roller crusher is mainly by gear-box, framework portion, fixedly roller, movable roller, linkage etc. are formed.Be the fixing critical piece of rod with the tooth crushing shell wherein, in the work, band tooth crushing shell directly contacts with ore and carries out fragmentation, and this requirement is with tooth crushing shell that very high hardness is arranged.So band tooth crushing shell is selected to contain chromium potassium steel usually, and carries out the tough processing of water after casting type.Because the rotation that does not stop when fixedly roller is worked, fixedly roller allows very little eccentric throw allowable, so roller core must be done static balancing test.In order to guarantee to be with tooth crushing shell and spare part still can guarantee static balance after installation, the weight difference of band tooth crushing shell must not be greater than 1 kilogram, so band tooth crushing shell must be processed.Because hardness is too high, heat is too big during Tool in Cutting, as untimely heat radiation, will make cutter annealing, and influence processing is so it is very low to add the rotating speed of equipment in man-hour.General processing mode carries out on planer-type milling machine.Crushing shell (abbreviation tooth plate) is filled up for four jiaos, make the tooth plate crown not contact bed surface, four jiaos compress with four pressing plates, then the base plane of tooth plate are processed; Since tooth plate pressing plate place processing less than, so after processing, residue face (the pressing plate place of compressing) needs the play pressing plate, remainder is continued to process, therefore, operation is very much inconvenient; In addition, because tooth plate hardness is big, the cutter rotating speed can not be too fast, and it is long especially to process the duration like this, and production efficiency is low.
Summary of the invention
The utility model is exactly at the problems referred to above, and a kind of processing unit (plant) of easy to use, double-geared roller crusher band tooth crushing shell that efficient is high is provided.
For realizing the utility model above-mentioned purpose, the utility model adopts following technical scheme, the utility model comprises base plate, the bottom of its structural feature base plate is a positioning key, between base plate and the upper plate stay pipe, side plate, the bottom of the lateral surface of side plate is the hook groove, and the both sides of side plate and the both sides of upper plate are respectively arranged with jackscrew; The top of the bolt in the stay pipe is pressing plate, and the bolt of pressing plate top is provided with setscrew nut, and the bolt between pressing plate and the upper plate is provided with nut.
The utility model beneficial effect: (1) is easy to use, efficient is high.Because of the present utility model simple in structure, convenient mounting and clamping on lathe, be installed once after, just need not the centering mold that is installed, and it once can process two workpiece simultaneously, has therefore solved the problem that conventional method need repeatedly be installed repeatedly, has improved production efficiency greatly.
(2) product quality height.The tooth plate because key piece location, the utility model employing device bottom surface, hook groove are installed, the inclined-plane pressing plate compresses, and jackscrew is finely tuned, and this mode tooth plate that is installed is stable, adds precision height in man-hour, has so just well guaranteed product quality.
Description of drawings
Fig. 1 is the utility model structural representation (promptly using state diagram).
The user mode figure that Fig. 2 positioning key of the present utility model works.
Fig. 3 is relational structure schematic diagrames such as positioning key and base plate.
Fig. 4 is the longitudinal sectional view of upper plate, lower plate etc.
The specific embodiment
As shown in the figure, the utility model comprises base plate 14, and the bottom of base plate 14 is a positioning key 2, is stay pipe 7, side plate 10 between base plate 14 and the upper plate 9, and the bottom of the lateral surface of side plate 10 is a hook groove 13, and the both sides of the both sides of side plate 10 and upper plate 9 are respectively arranged with jackscrew 3; The top of the bolt 15 in the stay pipe 7 is pressing plate 4, and the bolt 15 of pressing plate 4 tops is provided with setscrew nut 6, and the bolt 15 between pressing plate 4 and the upper plate 9 is provided with nut 8.
The bottom surface of pressing plate 4 can be intilted inclined-plane 16; So that the tooth plate 11 of both sides is inside, be more conducive to the fixing of tooth plate 11.
The lateral surface of side plate 10 is with the consistent curved surfaces of tooth plate 11 processing; So that flank of tooth applying side plate 10 is convenient to fit, be more conducive to processing.
Below in conjunction with description of drawings use of the present utility model: at first, the utility model device is fixed on the workbench 12 of double column milling machine, placed in the middle as far as possible, positioning key 2 times is 1 li of table positions groove, utilize bolt 15 to compress, at this moment without centering, positioning key 2 has been realized the precision of rectilinear direction.Again 11 times end hook faces of tooth plate place is stuck in hook groove 13 places of side plate 10, above pressing plate 4 press, wouldn't compress, utilize jackscrew 3 to carry out centering, centering rear fender 4 compresses, and just can process then.
Claims (3)
1. the processing unit (plant) of double-geared roller crusher band tooth crushing shell, comprise base plate (14), the bottom that it is characterized in that base plate (14) is positioning key (2), between base plate (14) and the upper plate (9) stay pipe (7), side plate (10), the bottom of the lateral surface of side plate (10) is hook groove (13), and the both sides of the both sides of side plate (10) and upper plate (9) are respectively arranged with jackscrew (3); The top of the bolt (15) in the stay pipe (7) is pressing plate (4), and the bolt (15) of pressing plate (4) top is provided with setscrew nut (6), and the bolt (15) between pressing plate (4) and the upper plate (9) is provided with nut (8).
