Abstract
A mechanism for milling the impeller inducer is centrifugal compressor on the ordinary milling machine has a longitudinal slide seat installed to the bench of vertical milling machine, an index head installed to the slide plate moving on the said longitudinal slide seat and the transverse slide plate and gib-headed screw installed on the said slide plate. A copying plate is installed to the said transverse slide plate. A weight is hung from the gib-headed screw via nylon string and pulley, forcing the roller always in contact with the side surface of copying plate. Its advantages are simple structure and high and stable quality of products.
Description
Technical field
The present invention relates to the device of the processing of centrifugal compressor guide wheel.
Background technology
Centrifugal compressor straight radial blade half-opened impeller has advantages such as single-stage pressure ratio height, intensity be good, extensively is used on medium and small compressor.The method of making half-opened impeller at present has numerical control system of milling and welding to make two kinds, the former the numerical control system of milling is to mill system by computer programming on five coordinate CNC milling machines, this processing method vane type line machining accuracy height, reliable in quality, the impeller intensity height, but five coordinate CNC milling machine prices are extremely expensive, processing charges is very high; The latter welds manufacturing, is first with blade compression molding shape, one by one blade is connect to be soldered on the wheel disc again, the shortcoming of this manufacture method is that the vane type line accuracy of manufacture is low, be subjected to compression molding, connect all multifactor influences such as welder's skill, heat treatment, the quality instability, impeller intensity is lower.
Summary of the invention
The objective of the invention is principle, design a kind of device that mills system centrifugal compressor impeller inducer with plain-milling machine according to the formation of impeller blade flow angle.
The shape of impeller inducer blade is based on that following principle forms: when promptly air-flow enters impeller inducer blade inlet limit, do not have mutual impact phenomenon, after air-flow entered blade, the relative velocity in longshore current road answered even transition to radial direction.Air-flow axially enters the speed of impeller, and each point is identical on the cross section, but the linear velocity of rotating vane each point increases gradually with radius its peripheral velocity from the root to the top.Therefore, the deflection that air-flow enters the blade relative velocity is that the increase with radius reduces, enter behind the blade many with parabolic transition to prismatic blade.Such blade shape is to obtain with general processing method at plain-milling machine.Device of the present invention is to process according to the formation principle of impeller blade, thereby can obtain accurate blade shape.
The technical solution used in the present invention is as follows:
It comprises the vertical slide that is installed on the vertical knee-type milling machine workbench, can on the slide plate that vertically slide is done to vertically move, the milling machine dividing head be installed, cross slide and hook screw are housed on the slide plate, travelling gear on the dividing head is meshed with the tooth bar that is fixed on cross slide, fixing master plate on the cross slide, turning rolls and pulley yoke are housed on the vertical knee-type milling machine workbench, and the pulley of the nylon rope on the hook screw on pulley yoke hung weight, and the roller on the turning rolls is withstood on the master plate side all the time.
The useful effect that the present invention has is: it promotes dividing head with master plate by roller and vertically moves according to the formation principle of impeller blade on plain-milling machine, finish the working angles of slotting cutter to impeller inducer blade curve.This apparatus structure is simple, and is easy for operation, constant product quality.

Fig. 1 is a structural principle schematic diagram of the present invention;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the vane type line at impeller inducer import average diameter place;
Fig. 4 is the molded lines of impeller inducer on master plate.
The specific embodiment
As Fig. 1, shown in Figure 2, it comprises the vertical slide 2 that is installed on the vertical knee-type milling machine workbench 1, can on the slide plate 3 that vertically slide 2 is done to vertically move, milling machine dividing head 4 be installed, cross slide 7 and hook screw 14 are housed on the slide plate 3, travelling gear 6 on the dividing head 4 is meshed with the tooth bar 8 that is fixed on cross slide 7, fixing master plate 9 on the cross slide 7, turning rolls 13 and pulley yoke 16 are housed on the vertical knee-type milling machine workbench 1, the pulley of nylon rope 15 on pulley yoke 16 on the hook screw 14 hung weight 10, and the roller on the turning rolls 13 11 is withstood on master plate 9 sides all the time.
As shown in Figure 3, Figure 4, according to the profile coordinate on the impeller inducer blade import average diameter, template curve equates at longitudinal direction with the impeller inducer curve, i.e. Δ X
1=Δ X, template curve has amplified K doubly at horizontal direction, i.e. Δ Y
1In=Δ Y/ π * 40 * π * d=K * Δ YK=40 * d/D formula: the average diameter mm of D-impeller inducer import department;
40-milling machine dividing head gearratio;
The reference diameter mm of d-travelling gear;
Δ X
1Δ X-template curve and the impeller inducer curve length on vertical a certain section;
Δ Y
1, Δ Y-template curve and impeller inducer curve be in the horizontal length on a certain section.
On common vertical knee-type milling machine, on dividing head 4, the travelling gear 6 on the dividing head 4 is meshed with tooth bar 8 on the cross slide 7, fixes a master plate 9 on the cross slide 7 and is pressed against on the roller 11 that is fixed on milling machine table with impeller inducer blank 5 clampings.Slotting cutter 12 downward certain depths, after shaking milling machine table 1 feed to slotting cutter and beginning to cut impeller inducer, the locking workbench, shake dividing head rotation feed, this moment, cross slide moved, master plate promotes dividing head by roller and vertically moves, and finishes the working angles of 12 pairs of impeller inducer blades of slotting cutter curve thus.
