[0015] This utility model includes a speed-regulating motor 2 disposed inside a main body housing 1; one end of the main body housing 1 is fixedly connected to a Morse taper shank 7, and a coupling 3 and a bearing 8 are disposed inside the other end of the main body housing 1; the output shaft of the speed-regulating motor 2 is connected to a main shaft 4 through the coupling 3; the main shaft 4 is fixed to the inner ring of the bearing 8; a chuck 5 is disposed at the outer end of the main shaft; the main body housing 1 is also provided with a tool holder connecting handle 6; the axis of the tool holder connecting handle 6 is perpendicular to the axis of the main shaft 4.
[0016] The main body shell 1 includes a cavity 101 for accommodating a speed-regulating motor, a cavity 102 for accommodating a coupling, and a cavity 103 for accommodating a bearing; the diameter of cavity 101 is larger than the diameters of cavity 102 and cavity 103; and cavity 102 and cavity 103 share a single shell.
[0017] The bearing 8 consists of two radial bearings 82 and one thrust bearing 81. The two radial bearings 82 are arranged side by side, with their outer radial sides abutting against the inner side of the cavity 3 103. The thrust bearing 81 is located on one side of the radial bearings 82 and abuts against the side wall of the cavity 3 103.
[0018] The Morse taper shank 7 and the taper shank flange 71 are an integral structure, and the taper shank flange 71 is fixed to the main body shell 1 by bolts.
[0019] The speed-regulating motor 2 is fixed inside the main body shell 1 by bolts.
[0020] Oil injection holes are provided in cavity 2 102 and cavity 3 103 (not shown in the figure).
[0021] The processing method and processing principle of this utility model
[0022] like Figure 2 As shown, when machining holes or keyways on shaft or sleeve parts, the two ends of the workpiece 11 are fixed on the lathe chuck 10 and the lathe tailstock 12, respectively. The power head is horizontally clamped on the lathe tool post 9 and the axis of the power head is aligned with the axis of the lathe spindle. The perpendicularity with the lathe spindle is checked, and a suitable drill or milling cutter is clamped. The speed control motor switch is turned on and the speed control button is rotated. The speed required for machining is adjusted by observing the motor speed on the digital display screen. Then, the small slide or large slide of the lathe is moved to machine the part.
[0023] As Figure 3 shown, when machining the center hole of large shaft parts, the power head tail part morse taper handle is installed in the adjusted lathe tailstock 12 sleeve, the front part of the power head shell is lightly hit with a copper rod to ensure that the power head is firmly connected with the tailstock sleeve, then the lathe tailstock is locked, the centering good large shaft center is aligned with the center drill clamped by the power head, the power head is started, the lathe tailstock handle is shaken, and the large shaft center hole is machined. If the center hole of the shaft has high precision requirements, a center stand 13 can be placed on the outer sleeve of the main shaft of the power head as auxiliary support, so that the rigidity of the power head is good during machining, and the precision of the machined center hole is higher. If the center hole of the shaft needs to be ground, a diamond special grinding head can be clamped on the power head for high-speed grinding of the center hole.
[0024] As Figure 4 shown, when grinding the shaft parts or sleeve parts, the power head is horizontally and longitudinally clamped on the lathe tool rest 9, the grinding wheel 15 is clamped on the power head through the connecting rod, the power head is started to grind the grinding wheel, then the lathe is started at low speed, the lathe slide plate is adjusted, and the slide plate is automatically fed to grind the parts.
[0025] As Figure 5 shown, when machining the flange hole on the disc part, a tool is used to draw a flange hole position on the machined part, the power head is also horizontally and longitudinally clamped on the lathe tool rest, then the lathe slide plate or the middle and small slide plates are moved according to the position of the line to align the position, and then the hole is accurately drilled. If the position accuracy of the hole is not high, the lathe chuck claw can be directly indexed to drill the hole.
[0026] The innovation point and important significance of the utility model are as follows:
[0027] 1. The power head has compact structure, can combine the power motor, the power head main shaft, the chuck and the connection part with the lathe into an integral whole, and is convenient and fast to clamp on the lathe.
[0028] 2. The power head can exert the characteristics and advantages of the power motor (brushless step speed regulating motor), such as large power, small size, high speed and wide speed regulating range.
[0029] 3. The problems that the ordinary lathe cannot machine the center hole of a large shaft, a long shaft or a large special-shaped workpiece, and the lathe cannot grind the center hole are solved.
[0030] 4. The power head used on the lathe can realize simple turning and milling, can machine the workpiece clamped on the lathe in horizontal, longitudinal or multi-angle directions through the offset small slide plate, and can save one or two processes during single piece machining or small batch machining, thereby improving machining efficiency.
[0031] 5、Some workpieces that are difficult to grind on a grinding machine can be ground on a lathe with a power head, because the power head is more convenient and fast to replace small grinding wheels and adjust the power head, and has high flexibility and freedom.
[0032] 6、It is suitable for small repair processing and does not occupy space.
