Description
Technical Field
The utility model relates to a tooling especially relates to a turbine case inlet end flange mills with clamping apparatus.
Background
Generally, when a flange at the air inlet end of a turbine box is milled, the flange at the air outlet end of the turbine box is positioned by the end face of the air outlet hole and the air outlet hole, the position of the flange at the air inlet end is manually adjusted, and after a workpiece is tightly pressed by a universal pressing plate, the flange at the air inlet end of the turbine box is milled, the whole process needs to be clamped and adjusted, the processing efficiency is low, the labor intensity of operators is high, and when the rotating speed of a main shaft exceeds 1500 revolutions per minute in the processing process and the feeding amount exceeds 0.4 millimeter, the phenomenon of cutter vibration often occurs, so that the surface roughness is difficult to guarantee.
SUMMERY OF THE UTILITY MODEL
The applicant carries out research and improvement aiming at the problems, and provides a milling clamp for a turbine box air inlet end flange, which has the advantages of simple and compact structure, low manufacturing cost, convenient, fast, firm and reliable clamping, improvement on production efficiency, reduction on the labor intensity of operators and guarantee on the processing quality.
In order to solve the technical problem, the utility model discloses a following technical scheme:
a milling clamp for a flange at the air inlet end of a turbine box comprises a base plate, a screw rod is perpendicular to the base plate, the lower end of the screw rod is fixedly connected with the base plate, a compression nut is arranged at the upper end of the screw rod, and a U-shaped pressing plate for compressing the turbine box is arranged below the compression nut; the first positioning pin and the second positioning pin are arranged on the base plate on one side of the screw rod.
The technical effects of the utility model reside in that:
the utility model discloses a turbine case inlet end flange mills adds clamping apparatus, simple structure is compact, low in manufacturing cost, clamping convenient and fast, firm reliable improves production efficiency, alleviates operation workman's intensity of labour, guarantees processingquality simultaneously.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
As shown in fig. 1, the utility model discloses a base plate 1, screw rod 4 perpendicular to base plate 1 sets up to screw rod 4's lower extreme fixed connection base plate 1, screw rod 4's upper end is equipped with gland nut 3, and gland nut 3's below is equipped with the U type clamp plate 2 that is used for compressing tightly turbine case 7, is used for fixing a position turbine case 7's first locating pin 5 and second locating pin 6 setting on screw rod 4 one side base plate 1.
When in-service use, the utility model discloses a base plate 1 is fixed on the work platform of machine tool, and screw rod 4 is emboliaed to turbine case 7 to with first locating pin 5 and 6 location turbine cases 7 of second locating pin, insert U type clamp plate 2, gland nut 3 screws, compresses tightly turbine case 7 location on anchor clamps through U type clamp plate 2, can mill the processing to the inlet end flange face of turbine case 7 this moment. After the milling is finished, the compression nut 3 is loosened (the compression nut 3 does not need to be taken down), the U-shaped pressing plate 2 is pulled out, and the turbine box 7 which is finished with the milling can be taken down. When packing into turbine case 7 next time, need not to take off gland nut 3, embolia screw rod 4 with turbine case 7, insert U type clamp plate 2, gland nut 3 of screwing can fix a position and compress tightly turbine case 7, whole clamping process convenient and fast, the location compresses tightly accurately, reliably, and the efficiency of production is improved, and the intensity of labour who alleviates the operation workman, simultaneously can greatly improve machining center main shaft rotational speed and feed volume, under the prerequisite of guaranteeing product quality, save the process time of this process, further improve work efficiency, guarantee the quality of machined surface.
