The explosive view of structure;Fig. 6 is casing for clock and watch folder in five shaft platform of processing casing for clock and watch bolt cantilever provided in an embodiment of the present invention
Has the structural schematic diagram at position.As shown in figs. 1 to 6, processing five shaft platform of casing for clock and watch bolt cantilever include hollow four axis 1,
Five axle suspension arms 2, servo motor 3, bolt mechanism 4, rotary chuck 5, speed change gear 6, fixture positioning disk and casing for clock and watch fixture;Five
Axle suspension arm 2 is horizontally placed on the side of hollow four axis 1;Servo motor 3 is set to the proximal end of five axle suspension arms 2, speed change gear 6, rotation
Turn the distal end that chuck 5, fixture positioning disk, casing for clock and watch fixture are successively set to five axle suspension arms 2 from bottom to top;3 energy of servo motor
Enough driving speed change gears 6 drive rotary chuck 5 to rotate, and rotary chuck 5, fixture positioning disk and casing for clock and watch fixture are successively fixed to be connected
It connects;Bolt mechanism 4 is set between servo motor 3 and rotary chuck 5;Bolt mechanism 4 is provided with telescopic positioning column 13, rotation
The circumferential direction for turning chuck 5 is provided with multiple locating slots 14;When rotary chuck 5 rotates to required angle position, positioning column 13 extends
It is inserted into the rotation that locating slot 14 prevents rotary chuck 5 afterwards.
On the basis of the above embodiments, as shown in Figure 4,5, further, the end of positioning column 13 is provided with trapezoidal convex
It rises, locating slot 14 is in compatible trapezoidal.In five shaft platform of bolt cantilever of the structure, the end of trapezoidal protrusion is smaller, bottom
Portion is larger;And trapezoidal locating slot 14 is open that larger, bottom is smaller, facilitates rotary chuck 5 and realizes rapidly in rotary course and inserts
Connect detent.And protrusion and the groove abrasion of trapezium structure are smaller, torque is larger.
On the basis of the above embodiments, as shown in Figure 4,5, further, week of multiple locating slots 14 along rotary chuck 5
To being uniformly arranged.In five shaft platform of bolt cantilever of the structure, the locating slot 14 being circumferentially uniformly arranged is carrying out locking positioning
It is convenient and efficient when control.In addition, 5 center of gravity of rotary chuck of homogeneous texture is overlapped with sized central, positioning accurate is further improved
Degree.
On the basis of the above embodiments, as shown in Figure 4,5, further, positioning column 13 is realized by the driving of cylinder 15 and is stretched
Contracting activity.In five shaft platform of bolt cantilever of the structure, cylinder 15 is controlled relative to hydraulic and motor control, and advantage is to move
Make rapid, reaction fastly, and compact-sized, the compact of entire mechanism.And on the numerical control rotating platform to run at high speed, control is dynamic
The reaction speed of work has tremendous influence to control precision.
It on the basis of the above embodiments, as shown in Figure 4,5, further, further include oil groove 16;Oil groove 16 is set to fixed
The outer of position column 13, for lubricating and cooling down.Since the moving speed of positioning column 13 is very fast, and use oil groove 16 can be right
Positioning column 13 plays the role of lubrication and cooling.
On the basis of the above embodiments, as shown in Figure 4,5, further, the perpendicular cross network structure of oil groove 16.Net
The oil groove 16 of shape structure can more preferably save grease, prevent grease from leaking, not only safety and sanitation, while extend overhaul of the equipments week
Phase reduces cost of equipment maintenance.
On the basis of the above embodiments, as shown in Fig. 3,4,5, further, speed change gear 6 includes harmonic wave speed changer.
On numerical control rotating platform, rotary chuck 5 frequently repeatedly rotates and locking, uses harmonic wave speed change gear 6 that can provide for equipment

The quick change positioning disk 7 and zero point magic chuck 8 of secondary connection.Modern manufacturing industry is more and more raw to small lot multi items even single-piece
Inclination is produced, and the desired delivery cycle is shorter and shorter.In order to produce the product of more multi items, more specifications, production unit is not
Not according to manufacturing special fixture the case where every kind of product and be installed on identical lathe, and every replace a kind of product just
A kind of fixture is needed replacing, the time for usually only replacing frock clamp just takes long time, and certain specialities or precision are wanted
The time for asking high product to consume on replacement frock clamp is more up to a few hours, under this just directly results in production efficiency sharply
Drop.For the efficiency for improving the debugging of small lot tooling, zero point magic chuck 8 comes into being.And quick change positioning disk 7 and zero point quick change folder
The composite structure of tool 8, improves the replacement efficiency and positioning accuracy of fixture.
On the basis of the above embodiments, as a shown in Figure 6, further, casing for clock and watch fixture includes pinboard 9, determines
Position seat 10 and pressing plate;Pinboard 9 is fixedly connected with zero point magic chuck 8, and positioning seat 10 is set on pinboard 9, and pressing plate fitting is set
It is placed in positioning seat 10, and forms cavity between positioning seat 10, for clamping casing for clock and watch.In five axis of bolt cantilever of the structure
In platform, pinboard 9 is used for connection function, and transmits the torque of servo motor 3.And positioning seat 10 and pressing plate are to fixed clock and watch
Shell, reach the adjustment of precise positioning and posture.
On the basis of the above embodiments, as a shown in Figure 6, further, pressing plate includes two substrates 11 and four folders
Gripping arm 12, two substrates 11 are symmetrical arranged, and four clamping limbs 12 extend from two substrates 11 are opposite respectively.In the bolt of the structure
In five shaft platform of cantilever, the shell of clock and watch is in symmetrical structure in length and breadth more, can symmetric clamp using four clamping limbs 12.And symmetrically divide
The substrate 11 of cloth then plays the role of fixed clamping arm 12.
