Abstract
The invention relates to the technical field of metalworking clamps, in particular to a skewed key slot milling clamp for a rotating shaft of a roller bed variable-frequency and variable-speed motor. The skewed key slot milling clamp comprises a base; the base is provided with a supporting slider; the supporting slider is connected with the base through screws; a supporting block lining is arranged in the supporting slider; a rotating shaft bearing guard is arranged in the supporting block lining; two sides of the base are respectively and fixedly provided with an adjusting baffle through the screws; one end of each adjusting baffle is connected with the base, and the other end of each adjusting baffle is connected with an adjusting screw; each adjusting screw is movably arranged on the corresponding adjusting baffle; the end face of one end of each adjusting screw is in contact with the supporting slider. According to the skewed key slot milling clamp disclosed by the invention, the adjusting screws can be adjusted according to the skewing dimension worked out according to the angle and the length on the rotating shaft, so that the supporting slider skews for a certain distance, and the angle of the milled key slot in the rotating shaft and the angle of a skewed slot in the inner diameter of a cast aluminum iron core are supposed to be consistent, and therefore the rotating shaft and the cast aluminum iron core are matched stably when shrinkage fit is performed on the rotating shaft and the cast aluminum iron core.
Description
Technical field
The present invention relates to a kind of slotting attachment, especially a kind of fixture for the rotating shaft iron core shelves peripheral milling taper key slot machining in roller-way adjustable frequency motor.
Background technology
In recent years, along with the electronic technology of China's metallurgy industry, computer technology, the developing rapidly of automated control technology, a lot of iron and steel enterprise significantly undergoes technological transformation, in transmission system, greatly part all adopts current and frequency conversion speed governing, particularly auxiliary biography mechanically all adopts ac variable frequency speed regulation, instead of DC speed regulation in the past completely.Motor AC variable-frequency control technique is current economize on electricity, improve technological process with improve the quality of products and environmental protect, Promote Technology a kind of trend.Frequency control is with the speed governing of its excellence and play braking ability and power savings, and the auxiliary drive motor of its milling train all adopts roller-way frequency-conversion and speed-regulation motor.
The rotating shaft Xiyanping injection of existing threephase asynchronous, only to the milling of shaft extension and fan two ends keyway, and centre does not have taper key groove; Normally adopt vertical knee-type milling machine that rotating shaft bearings at both ends shelves are placed on two contour V-blocks and adjust institute's groove milling position, compress Xiyanping injection (for straight keyway is not with angle) by pressing plate.But for rotating shaft speciality, cylindrical is thick, in addition keyway is on a former and band angle, and needing to ensure with front end shaft extension keyway at the first-class processing request of same center line, existing equipment is cannot process, large-scale milling machine special equipment (or the processing of external coordination gantry mill) need be ordered, and it is long to buy new equipment procurement cycle, needs very large fund, also affect delivery date, and external coordination is expensive, increase cost.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of roller-way frequency control motor rotating shaft milling oblique key groove clamp.
The technical solution adopted for the present invention to solve the technical problems is: the oblique key groove clamp of a kind of roller-way frequency control motor rotating shaft milling, comprises base, described base is provided with supporting slide block; Described supporting slide block is connected with base by screw; Rest pad lining is provided with in described supporting slide block; Shaft bearing shelves are placed in described back-up block lining; The both sides of described base are fixed with regulating fender respectively by screw; One end of described regulating fender is connected with base, and the other end of regulating fender is connected with adjustment screw; Described adjustment screw is movably arranged on regulating fender; One end end face of described adjustment screw contacts with support slipper.
Further, for the ease of changing and maintenance, back-up block lining of the present invention is fixed by screws in support slipper.
Further say, base bottom of the present invention is provided with flat key by screw.
This fixture of the present invention is mainly to seat No. YGP400 and the above roller-way adjustable frequency motor of large gauge motor, and rotating shaft is welded as a whole by six roots of sensation Q235 plate and 35CrMo round steel, and spacing is equal, after heat treatment machines.
The invention has the beneficial effects as follows, solve the defect existed in background technology, the size of skew can have been calculated according to the angle in rotating shaft and length, adjustment adjustment screw makes supporting slide block offset certain distance, ensure that the keyway angle of institute's milling in rotating shaft should be consistent with the skew slot angle of cast aluminium iron core internal diameter, smooth co-operation during hot jackets both making.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
In figure: 1, regulating fender; 2,10, screw; 3, adjustment screw; 4, supporting slide block; 5, bolt; 6, shaft bearing shelves; 7, rest pad lining; 8, base; 11, flat key.
Detailed description of the invention
The present invention is further detailed explanation with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
The oblique key groove clamp of a kind of roller-way frequency control motor rotating shaft milling as shown in Figure 1, comprises base 8, base is provided with supporting slide block 4; Supporting slide block is connected with base by screw; Rest pad lining 7 is provided with in supporting slide block; Shaft bearing shelves 6 are placed in back-up block lining; The both sides of base are fixed with regulating fender 1 respectively by screw 2; One end of regulating fender is connected with base, and the other end of regulating fender is connected with adjustment screw 3; Adjustment screw is movably arranged on regulating fender; One end end face of adjustment screw contacts with support slipper.Back-up block lining is fixed by screws in support slipper.Base bottom is provided with flat key 11 by screw 10.
During use, be fixed on milling machine table by the base of two fixtures, the shelves of opening of two bases add 20mm calculating again by the distance that rotating shaft two bearings shelves are takeed on; Again supporting slide block is put into base screw pretension, then rotating shaft is placed on supporting slide block, by the linearity of a former correction center line of milling (both sides are symmetrical) in adjustment rotating shaft.First pointer on two supports slide block is aimed at the position of on scale-board zero, then adjustment screw makes supporting slide block offset certain distance (calculated the size of skew according to the angle in rotating shaft and length, scale-board is on base).Regulate at other end rightabout again, and the size that two ends regulate is equal, fastening supporting slide block, then clamping shaft groove milling.By process certification and hot jacket assembling, meet drawing requirement completely, get a desired effect.
The just the specific embodiment of the present invention described in above description, various illustrating is not construed as limiting flesh and blood of the present invention, person of an ordinary skill in the technical field after having read description can to before described detailed description of the invention make an amendment or be out of shape, and do not deviate from the spirit and scope of the invention.
