At.Servo motor is connected by L-type plate with support plate, the power plant as retaining mechanism.Transmission shaft and servo motor phase
Even, cam and incomplete bevel gear are co-axially mounted, and by changing the energization phase sequence of servo motor, the connection between joint face is disconnected
Offer power is provided.Cam is in contact with cross guide rail surface, and cam follows improved sinusoidal acceleration characteristics of motion, passes through cam
Rotation, driving cross guide rail move forward.Sliding block is connected with guide rail strut constitutes guide assembly, and guide rail strut is mounted on cross and leads
In rail sliding slot, cross guide rail can drive guide assembly to move in a straight line.Spring is mounted between support plate and cross guide rail, is being led
Play limit damping in rail assembly movement.Groove bevel gear is installed on the supporting plate, by the sine on groove bevel gear
Shape groove, guide rail strut is tangent with sinusoidal groove always, by the rotation of groove bevel gear, guide assembly can be driven radially to move
It is dynamic.Joint face is connected by boss with support plate, and the joint face structure with external connection unit locking is formed.
The beneficial effects of the invention are as follows:
1. connection type used by mechanism is Purely mechanical connection, bonding strength and rigidity are larger, affected by environment smaller,
Suitable for working under complicated space environment.
2. Cam Motion Principle designed by mechanism be improved sinusoidal acceleration, such characteristics of motion maximum speed and
The value of peak acceleration is all reduced, i.e., suffered impact force can be preferably minimized, and is highly suitable for self-reorganization robot
Connection locking.
3. groove on mechanism groove bevel gear is sinusoidal, and the guide rail strut at the beginning and end of groove
It is vertical with the tangential direction of groove, there is certain self-lock ability, ensure that the reliability of connection.
Detailed description of the invention
Mechanism is further illustrated with reference to the accompanying drawing.
Attached drawing 1:Cam lock holding mechanism overall schematic
Attached drawing 2:Cam lock holding mechanism partial enlarged view
Attached drawing 3:Cam lock holding mechanism locked position figure
In figure:1 servo motor, 2 L-type plates, 3 support plates, 4 transmission shafts, 5 cams, 6 incomplete bevel gears, 7 cross guide rails, 8 is sliding
Block, 9 guide rail struts, 10 springs, 11 groove bevel gears, 12 joint faces, 13 boss.
Specific embodiment
The following is further explained with reference to the attached drawings specific structure and embodiment of the invention.
Structure composition of the invention as shown in Figure 1, Figure 2 and Figure 3.Improved sinusoidal acceleration cam lock holding mechanism is by servo
Motor(1), L-type plate(2), support plate(3), transmission shaft(4), cam(5), incomplete bevel gear(6), cross guide rail(7), sliding block
(8), guide rail strut(9), spring(10), groove bevel gear(11), joint face(12), boss(13)Composition.Servo motor(1)It borrows
Help L-type plate(2)With support plate(3)It is connected, the power plant as retaining mechanism.Transmission shaft(4)With servo motor(1)Phase
Even, cam(5)With incomplete bevel gear(6)It is co-axially mounted, by changing servo motor(1)Energization phase sequence, be joint face it
Between connection disconnect provide power.Cam(5)With cross guide rail(7)Surface is in contact, cam(5)Follow improved sinusoidal acceleration
The characteristics of motion is spent, cam is passed through(5)Rotation drives cross guide rail(7)It moves forward.Sliding block(8)With guide rail strut(9)Be connected structure
At guide assembly, guide rail strut(9)It is mounted on cross guide rail(7)In sliding slot, cross guide rail(7)Guide assembly can be driven to do straight line
Movement.Spring(10)It is mounted on support plate(3)With cross guide rail(7)Between, the work of limit damping is played in guide assembly movement
With.Groove bevel gear(11)It is mounted on support plate(3)On, by groove bevel gear(11)On sinusoidal groove, guide rail strut
(9)Always tangent with sinusoidal groove, pass through groove bevel gear(11)Rotation, guide assembly can be driven to move radially.Connection
