Seat, the ladder-type trough of no less than 2 is provided on the clamping fixture seat, and either V-groove is set between adjacent ladder-type trough or V-groove
One piece of fixation clip is equipped with, the fixation clip is connected to by fixing bolt above adjacent ladder-type trough or V-groove.
Further, support plate is provided in the housing, the motor is vertically arranged and fixes on the supporting plate, the electricity
Arbor stretches out support plate lower surface and is connected with driving gear.
Further, the output shaft upper end is connected on the supporting plate by rolling bearing, and the support plate lower surface is set
There is the groove for accommodating rolling bearing.
Further, it is provided with sleeve between the driven gear and rolling bearing.
Further, the support base of a pair of opposing is provided between 1 pair of clamping fixture seat, is provided on the support base
With the ladder-type trough either one-to-one ladder-type trough I of V-groove or V-groove I.
Further, one piece of fixation clip I, the fixation clip I are provided between adjacent ladder-type trough I or V-groove I
With fixation clip stagger setting.
Further, the clamping fixture seat is provided at both ends with the bolt being fixed on a mounting board.
Further, the ladder-type trough or V-groove are arranged to 2,4,6,8.
The beneficial effects of the present invention are：
Keyway attachment of the present invention is by being provided with milling cutter side by side and can install 2 or 2 or more workpiece simultaneously
Frock clamp, motor can synchronous 2 milling cutters carry out rotary work, can be simultaneously in 2 works under the cooperation of frock clamp
Keyway is processed on part axis, reduces fixture built-up time, improves the utilization rate of processing benefit and equipment.

Utility model is described in further detail with reference to the accompanying drawings and detailed description.
It is the sectional view of keyway attachment of the present invention as shown in Figure 1, is illustrated in figure 2 keyway attachment of the present invention
Top view, a kind of keyway attachment of the present invention, including process tool and work piece holder, the process tool includes 1 He of housing
The motor 3 being arranged on housing 1 is provided with the driving gear 4 being connected with motor 3 in the housing 1, and the driving gear 4 connects
A pair of driven gear 5 engaged with driving gear 4 is connected to, the output shaft 6 being vertically arranged, institute are set on the driven gear 5
It states output shaft 6 and extends the other end of 1 lower surface of housing and be provided with milling cutter 7,1 lower end of housing is provided with dismountable lower cover
Plate 11, the output shaft 6 are supported on by hydrostatic bearing 8 on lower cover 11, and the work piece holder exists including a pair of opposing
Clamping fixture seat 13 on installing plate 12 is provided with the ladder-type trough 16 or V-groove of no less than 2 on the clamping fixture seat 13, adjacent
Ladder-type trough 16 or V-groove between be provided with one piece of fixation clip 14, the fixation clip 14 is connected by fixing bolt 15
Above adjacent ladder-type trough 16 or V-groove.
The present embodiment is driven output shaft 6 to rotate simultaneously, is passed through by a pair of of output shaft 6 with 3 synchronized links of motor, motor
Milling cutter 7 has been arranged side by side on output shaft and the frock clamp of 2 or 2 or more workpiece, motor energy can be installed simultaneously
Enough synchronous 2 milling cutters carry out rotary work, under the cooperation of frock clamp, can process keyway on 2 workpiece spindles simultaneously, subtract
