As shown in fig. 17 (iii), when OB is rotated to the position collinear with AB, OB and AB are both perpendicular to AC, the four-bar linkage is at the dead point position, the friction locking mechanism 1 is in the self-locking state, and at this time, the self-locking state of the friction locking mechanism 1 is not released no matter how external force is applied to AC.
When OB is rotated counterclockwise from the position shown in FIG. 17 (III), OB and AB are no longer collinear, and neither OB nor AB is perpendicular to AC, so that the self-locking state is released, and the position is shown in FIG. 17 (IV).
According to the scheme, the position (III) in the figure 17 is selected as a locking state, and the position IV in the figure 17 is selected as an opening state according to actual needs.
the actual state shown in fig. 17 (iii) is the locked state shown in fig. 11 (II), and in actual use, the operator rotates the locking handle 1a to rotate the upper rotating rod 1b to a position which is coincident and collinear with the middle connecting rod 1c and perpendicular to the locking connecting rod 1d, so that the friction type locking mechanism 1 is in the locked state, and the position is convenient for the operator to observe and use.
The actual state shown in fig. 17 (iv) is the opened state shown in fig. 11 (I), and in actual use, the operator rotates the locking handle 1a counterclockwise to make the upper rotating rod 1b no longer coincide with the middle connecting rod 1c, and the friction type locking mechanism 1 will be unlocked and in the opened state.
The use method of the angle adjusting module comprises the following steps:
As shown in fig. 19 to 22, a combined machining and manufacturing platform can be constructed based on an angle adjustment module, and the angle adjustment module can be used as a connection adjustment component between two platforms to adjust and fix a relative angle between the two platforms, and the angle adjustment range is ± 90 °. The combined machining and manufacturing platform constructed by the angle adjusting module can be used for additive manufacturing, subtractive manufacturing, equal-material manufacturing, assembly manufacturing and other occasions, parts, mechanisms, assemblies, devices, equipment and the like are fixed in a mode of bolts, clamping grooves, magnetic attraction, welding, adhesion and the like, the included angle between the two platforms is flexibly changed by adjusting the angle adjusting module according to actual working conditions, the requirements of space positioning and clamping in production are met, the characteristic of poor flexibility of working platforms such as traditional machining, manufacturing, assembly and the like is broken through, and smooth proceeding of the manufacturing and assembling process is guaranteed.
In practical use, the mounting seat 3a2 on the top connecting block 3 is used for connecting the fixed side auxiliary platform M1, the bottom connecting block 5 is used for connecting the fixed main platform M2, after the included angle between the two platforms is adjusted to a certain position, the clamping and positioning mechanism 4 is rotated to make one side end face of the clamping and positioning disk 2e6 contact with the positioning clamping wheel 4a, and the clamping and positioning disk 2e6 is clamped and positioned by the positioning clamping wheel 4a, as shown in fig. 21; under the action of the positioning clamping wheel 4a, the end surface of the other side of the clamping positioning disc 2e6 is contacted with the end surface of the locking shaft fixing seat 5b close to the side of the clamping positioning mechanism fixing seat 5c, so that the floating type locking shaft 2 is initially positioned by utilizing the friction force applied to the end surfaces of the two sides of the clamping positioning disc 2e 6. However, the clamping force of the clamping and positioning mechanism 4 on the floating type locking shaft 2 is limited, and only the included angle between the top connecting block 3 and the bottom connecting block 5 can be preliminarily positioned, so that other external forces applied to a platform connected with the angle adjusting mechanism cannot be borne. Therefore, the clamping and positioning mechanism 4 is suitable for trial adjustment of the positional relationship between the side auxiliary platform M1 for the top manufacturing process and the main platform M2 for the bottom manufacturing process in the working environment, so as to determine the optimum spatial angular position.
Then, the lock lever 1a is rotated to lock the friction lock mechanism 1, and the lock friction plate 1f is in contact with the friction plate 2a1, and the lock friction plate 1f is coaxial with the friction plate 2a1, as shown in fig. 18. During locking, the locking friction disc 1f gradually contacts the friction disc 2a1, pushing the friction disc 2a1 to slide the friction locking shaft 2a toward the locking shaft holder 5b under the cooperation of the guide structure 2e1 and the guide groove 2a 4. Since the clamping positioning disc 2e6 at the other end of the floating locking shaft 2 has been clamped by the clamping wheel 4a, the guide transmission shaft 2e cannot move axially, so the spring 2b is compressed. The elastic force generated by the spring 2b is used as the positive pressure on the contact surface of the locking friction disc 1f and the friction disc 2a1, and further, the friction force is generated to fix the circumferential rotation position of the floating type locking shaft 2. Because the spline 2e4 is in connection fit with the spline hole 3c through an involute spline, after the floating type locking shaft 2 is fixed, the position of the top end connecting block 3 is also fixed, and thus the fixing of the angle position between the side auxiliary platform M1 and the main platform M2 is realized.
the contact position of the locking friction disc 1f and the friction disc 2a1 when the friction type locking mechanism 1 is in a locking state can be changed by adjusting the length of the friction disc adjusting rod 1e penetrating through the front hole 1d3 of the locking connecting rod, and further the compression amount of the spring 2b is changed, so that the friction force borne by the floating type locking shaft 2 in the locking state can be adjusted.
In addition, the position of the adjusting baffle plate 2d can be adjusted, the spring 2b is further adjusted to provide elastic force, so that the friction force of the contact surface between the locking friction disc 1f and the friction disc 2a1 is in a proper range, and the two friction discs can slide relatively after the side auxiliary platform M1 or the main platform M2 is overloaded due to stress, so that the overload protection effect is achieved, and damage to a machine tool and other equipment is avoided.
after the manufacturing process is completed, the locking handle 1a is rotated downward to separate the locking friction disk 1f from the friction disk 2a1, so that the locking state of the angle adjusting module is released, and then the clamping and positioning mechanism 4 is rotated to release the positioning state of the angle adjusting module.
The clamping and positioning mechanism 4 cannot be rotated first, so that the guide transmission shaft 2e cannot slide axially under the action of the elastic force of the spring 2b under the condition that the locking friction disc 1f is in contact with the friction disc 2a1, and the locking friction disc 1f and the friction disc 2a1 cannot be locked due to insufficient friction force and slip occurs, so that the position of the side auxiliary platform M1 cannot be fixed and move, and further safety accidents are caused.
This embodiment is only illustrative of the patent and does not limit the scope of protection thereof, and those skilled in the art can make modifications to its part without departing from the spirit of the patent.
