Description
Technical Field
The utility model relates to a machine tooling field, especially a frock is used in pump impeller blade milling process.
Background
Milling is a machining method for cutting a workpiece using a rotating multi-edged tool (milling cutter), which rotates during operation to perform milling using a plurality of cutter teeth provided on the outer circumference of the milling cutter. When the rotating milling cutter does a feeding action towards the workpiece, a partial circular shape can be machined on the workpiece, in most cases, the arc length of the partial circular shape is a minor arc, but in some cases, the arc length of the partial circular shape to be machined is larger (such as certain special-shaped impeller blades) and can reach the semi-circle or even the major arc, and the effective machining part of the milling cutter of the traditional milling device cannot reach the semi-circle degree, so that the machining operation cannot be realized.
SUMMERY OF THE UTILITY MODEL
The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit, rationally distributed, can process out the great shape of central angle's pump impeller frock for blade milling process
The technical solution of the utility model is that: the utility model provides a frock is used in pump impeller blade milling which characterized in that: the tool comprises a shell, the shell consists of a left shell 1 and a right shell 2 which are connected with each other, a main shaft 3 is rotatably supported in the shell 1, the main shaft 3 is connected with a driving gear 4 key positioned in the shell in a key mode, an adjusting gear shaft 5 is further rotatably supported in the shell 1, an adjusting gear 6 is arranged on the adjusting gear shaft 5, the adjusting gear 6 is meshed with the driving gear 4, the top end of the adjusting gear shaft 5 is movably connected in a first arc-shaped groove 7 arranged on the surface of the shell 1, a sliding seat 8 is arranged at the bottom end of the adjusting gear shaft 5, the sliding seat 8 is slidably connected in a second arc-shaped groove 9 arranged in the shell 1,
be connected with left blade disc 10 on the casing 1 of a left side, be connected with on the casing 2 of the right side with the right blade disc 11 of left blade disc 10 symmetric distribution, left side blade disc 10 and right blade disc 11 are provided with between the blade disc about for two by the disc cutter 12 of left and right sides blade disc centre gripping, the sword tooth part and the 6 external tooth part phase-matches of adjusting gear of disc cutter 12 outward flange, just the disc cutter sword tooth part still with the 6 mutual interlocks of adjusting gear.
Compared with the prior art, the utility model, have following advantage:
this kind of structural style's pump impeller blade frock for milling, its simple structure, design benefit, it is rationally distributed, it is to the limitation that traditional milling equipment exists, a milling structure of no main shaft drive is designed, it utilizes the gear to stir the sword tooth part on the milling cutter, thereby drive the high-speed rotation of milling cutter in order to realize milling's operation, it does not need the pivot of setting up in disc milling cutter center department to come the rotation of driving disc milling cutter, but utilizes a pair of left blade disc and right blade disc to centre gripping disc milling cutter, consequently, disc milling cutter's effective processing part is bigger (the degree that effective processing part can reach the major arc), thereby can process bigger (the degree that can reach the major arc equally) circular arc part. The tool has the advantages of simple manufacturing process and low manufacturing cost, so the tool is particularly suitable for popularization and application in the field and has a very wide market prospect.

Detailed Description
The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1, 2, and 3: a tool for milling pump impeller blades comprises a shell serving as a base, wherein the shell is composed of a left shell 1 and a right shell 2 which are connected with each other, a main shaft 3 is rotatably supported in the shell 1, the main shaft 3 is connected with a driving gear 4 key positioned in the shell in a key mode, an adjusting gear shaft 5 is further rotatably supported in the shell 1, an adjusting gear 6 is arranged on the adjusting gear shaft 5, the adjusting gear 6 is mutually meshed with the driving gear 4, the top end of the adjusting gear shaft 5 is movably connected in a first arc-shaped groove 7 arranged on the surface of the shell 1, a sliding seat 8 is arranged at the bottom end of the adjusting gear shaft 5, the sliding seat 8 is slidably connected in a second arc-shaped groove 9 arranged in the shell 1,
be connected with left blade disc 10 on the left side casing 1, be connected with the right blade disc 11 with left blade disc 10 symmetric distribution on the right side casing 1, be provided with the disc milling cutter 12 of blade disc centre gripping about by between left side blade disc 10 and the right blade disc 11, the sword tooth part and the 6 external tooth part phase-matches of adjusting gear of disc milling cutter 12 outward flange, just the sword tooth of disc milling cutter 12 still interlocks each other with adjusting gear 6.
The utility model discloses pump impeller blade milling process is with work process of frock as follows: firstly, selecting a disc milling cutter 12 with a proper specification according to the radius of an arc surface to be machined, clamping the disc milling cutter 12 by using a left cutter disc 10 and a right cutter disc 11 (the disc milling cutter 12 can still rotate relative to the left cutter disc and the right cutter disc), adjusting the relative positions of an adjusting gear shaft 5 and a first arc-shaped groove 7 and a second arc-shaped groove 9, ensuring that an adjusting gear 6 can be meshed with a driving gear 4 and the disc milling cutter 12 simultaneously, starting a motor connected with a main shaft 3, driving the main shaft 3 to rotate by the motor, further driving the driving gear 4 to rotate, transmitting the torque to the adjusting gear 6 by the driving gear 4, and finally driving the disc milling cutter 12 to rotate by the adjusting gear 6 to enable the device to be close to a workpiece to be machined (or enabling the workpiece to be close to the disc milling cutter 12), thereby realizing milling operation;
since the disc cutter 12 in the present apparatus is not driven by a shaft connected to the center thereof, the effective processing range is wider, a semicircular or even major arc state can be achieved,
when the disc milling cutter 12 of another specification needs to be replaced, the relative positions between the gear shaft 5 and the first arc-shaped groove 7 and the second arc-shaped groove 9 can be adjusted according to actual conditions, so that the adjusting gear 6 can be kept in a state of being meshed with the driving gear 4 and the disc milling cutters 12 of different specifications simultaneously, namely, the device can be used for installing the disc milling cutters 12 of different specifications to realize milling.
