The specific structure and connection manner of the positioning end 2 and the switching end 1 of the sleeve switching mechanism 100 will be specifically described as follows:
in this embodiment, the switching end 1 of the sleeve switching mechanism 100 includes a sleeve positioning assembly 3, a clamping assembly 4 and at least one target sleeve 5, wherein the sleeve positioning assembly 3 is connected with the positioning end 2 of the sleeve switching mechanism 100, the positioning end 2 of the sleeve switching mechanism 100 includes a column, the target sleeve 5 is disposed on the sleeve positioning assembly 3, the sleeve positioning assembly 3 includes a positioning plate 31, a positioning support cylinder 32, a first return spring (not shown), and a limiting pin 33, wherein the positioning plate 31 is connected with the positioning end 2 of the sleeve switching mechanism 100, that is, the positioning plate 31 is fixedly mounted on the column, one side of the positioning plate 31 is provided with a receiving hole 34, and the positioning support cylinder 32 is received on the receiving hole 34 of the positioning plate 31.

The inside of the positioning support cylinder 32 is relatively penetrated and has a morphology adapted to the positioning connection end 51 of the target sleeve 5 so as to stably mount the target sleeve 5 in the positioning support cylinder 32 through the positioning connection end 51 thereof. The first return spring is provided at the side of the morphology for having a return elastic force after the positioning connection end 51 of the target sleeve 5 is pressed. The stopper pin 33 is disposed so as to penetrate the circumferential end surface of the positioning support tube 32, and is capable of abutting against the positioning connection end 51 of the target sleeve 5 accommodated in the positioning support tube 32. The process of installing the target sleeve 5 inside the positioning support cylinder 32 is as follows: after the bolt connection end 52 of the target sleeve 5 passes through the positioning support cylinder 32, the positioning connection end 51 of the target sleeve 5 is assembled to the morphological structure, and the limiting pin 33 clamps the positioning connection end 51 while compressing the first return spring, so as to limit the movement of the target sleeve 5. When the target sleeve 5 needs to be taken out, the positioning connection end 51 of the target sleeve 5 is pressed again, and the clamping position of the positioning connection end 51 of the target sleeve 5 and the limiting pin 33 is misplaced, so that the target sleeve 5 is ejected under the reset elasticity of the first reset spring, and the target sleeve 5 is mounted and dismounted.
It should be noted that the positioning connection end 51 of the target sleeve 5 includes a first positioning connection structure 511 and a second positioning connection structure 512, where the first positioning connection structure 511 is located on an outer wall of the positioning connection end 51, the first positioning connection structure 511 is adapted to a morphological structure of an interior of the positioning support cylinder 32, and the first positioning connection structure 511 is assembled to the morphological structure of the interior of the positioning support cylinder 32.

Further, in this embodiment, in order to facilitate adjusting the sleeve positioning assembly 3 to a position matching with the bolt on the workpiece, the sleeve positioning assembly 3 further includes a second rotating motor (not shown) and a second connecting rotating shaft (not shown), specifically, the second rotating motor is connected with the positioning end 2 of the sleeve switching mechanism 100 and may be fixedly disposed in the upright post, the second rotating motor is connected with one end of the second connecting rotating shaft to drive the second connecting rotating shaft to rotate, the other end of the second connecting rotating shaft is connected to the positioning plate 31, and the second rotating motor drives the second connecting rotating shaft to rotate so as to drive the positioning plate 31. Based on the positioning support cylinder 32 being arranged on the positioning plate 31, the target sleeve 5 is arranged in the positioning support cylinder 32, so that when the positioning plate 31 rotates, the target sleeve 5 also synchronously rotates, and further the target sleeve 5 is automatically adjusted to a position matched with a bolt on a workpiece.
After the target sleeve 5 is assembled on the positioning support cylinder 32, in order to further improve the stability of the assembly of the target sleeve 5, a clamping assembly 4 is provided, and a fixing portion of the clamping assembly 4 is connected with the positioning end 2 of the sleeve switching mechanism 100, or a fixing portion of the clamping assembly 4 is connected with the positioning plate 31 of the cylinder positioning assembly, so as to rotate synchronously with the positioning plate 31 of the cylinder positioning assembly. The clamping part of the clamping assembly 4 can clamp the target sleeve 5 on the sleeve positioning assembly 3. Specifically, the clamping assembly 4 includes a support base 41, a second driving cylinder 42, a rotating shaft 43, a swinging block 44, and a clamping member 45. The supporting seat 41 is connected with the positioning plate 31 or directly connected with the upright post. The second driving cylinder 42 is fixedly arranged on the supporting seat 41, the rotating shaft 43 is movably arranged on the supporting seat 41, and the axial direction of the rotating shaft 43 is arranged along the horizontal direction. The swinging block 44 is disposed on the rotating shaft 43, and the swinging block 44 is connected with the output end of the second driving cylinder 42, and when the second driving cylinder 42 extends in the vertical direction, the swinging block 44 can be driven to rotate according to a first preset rotation angle through the rotating shaft 43. The holder 45 is provided on the swinging block 44 and has a holding angle with respect to the target sleeve 5. When the swinging block 44 swings according to the first preset rotation angle, the holding member 45 swings from the initial position to the holding position with the target sleeve 5 according to the holding angle, and presses and positions the target sleeve 5. The first preset rotation angle and the clamping angle are determined by the rotation of the swinging block 44 and the setting position and the swinging angle of the clamping piece 45. Moreover, the length of extension of the second drive cylinder 42 in the vertical direction also determines the first preset rotation angle and the clamping angle at the same time.
In the present embodiment, the clamp 45 includes a connection arm 451 and clamping claws 452, wherein one end of the connection arm 451 is connected to a designated position of the swinging block 44, the other end is connected to the clamping claws 452, the clamping claws 452 have clamping structures 453 adapted to the target sleeve 5, and the number of the clamping structures 453 is at least two. The number of the clamping structures 453 corresponds to the number of the positioning support cylinders 32. The direction of the pressure in which the clamp 45 presses the target sleeve 5 is mainly vertically downward. The gripper jaw 452 may define three degrees of freedom of the target sleeve 5 in the horizontal direction.
In the present embodiment, in order to further clamp the target sleeve 5, the clamping assembly 4 further includes a clamping arm (not shown), a second return spring (not shown), a linkage belt (not shown), and a third driving cylinder (not shown). Wherein, the third actuating cylinder sets up on the link 451, and the second reset spring sets up in the relative wall of the clamp structure 453 of gripper jaw 452, and the centre gripping arm butt is in the second reset spring to connect in the one end of linkage area, the linkage area runs through the second reset spring and makes the other end of linkage area and the output of third actuating cylinder be connected. In this embodiment, a communicating hole may be provided on the wall of the clamping claw 452, and a protecting sleeve is sleeved in the communicating hole, and the linkage belt penetrates through the second return spring, and the other end of the linkage belt penetrates through the protecting sleeve and then is connected with the output end of the third driving cylinder. The wall body of the clamping claw 452 is provided with the communication hole, so that the linkage belt is arranged in the communication hole, and the aesthetic property of the whole structure can be improved. The output end of the third driving cylinder contracts to drive the linkage belt to drive the clamping arm to move towards the direction of compressing the second reset spring, so that the clamping arm is in an unclamped state. On the contrary, the output end of the third driving cylinder is reset, the second reset spring enables the clamping arm to be in a clamping state through self reset elastic force, and meanwhile the clamping arm straightens the linkage belt.
Of course, in other examples, the above structure may be other structures, for example, a group of clamping mechanisms (not shown) may be added separately, the clamping mechanisms include a fourth driving cylinder and a clamping arm, the fourth driving cylinder is disposed on the positioning plate 31 of the cylinder positioning assembly, one end of the clamping arm is connected to the fourth driving cylinder, and the other end of the clamping arm can be clamped with the target sleeve 5, and the clamping and loosening states of the clamping arm are driven by the extending and retracting states of the fourth driving cylinder.
In addition, in this embodiment, in order to realize automatic replacement of the corresponding target sleeve 5 by the clamping assembly 4, the second driving cylinder 42 may perform a retracting action in the vertical direction, where the retracting action is performed at the initial position, that is, the clamping member 45 is in a state of not pressing the target sleeve 5, and the second driving cylinder 42 performs the retracting action to drive the swinging block 44 to rotate through the rotating shaft 43 according to the second preset rotation angle, where the rotation direction of the second preset rotation angle is opposite to the rotation direction of the first preset rotation angle. When the swinging block 44 swings at the second preset rotation angle, the holding member 45 swings from the initial position to the holding position where it can be held with the target sleeve 5 to be replaced according to the holding angle, thereby holding the target sleeve 5 (the holding operation is performed by the holding mechanism described above). After the target sleeve 5 is clamped, the second driving cylinder 42 performs an extending action to drive the swinging block 44 to reset to the initial position and continues to perform the extending action to drive the swinging block 44 to rotate through the rotating shaft 43 according to the first preset rotating angle, when the swinging block 44 swings according to the first preset rotating angle, the clamping piece 45 swings from the initial position to a position capable of being assembled with the positioning support cylinder 32 according to the clamping angle, and a new target sleeve 5 is assembled in the positioning support cylinder 32 and then pressed for positioning. Of course, the previous target sleeve 5 may be taken out to perform the reverse execution steps as described above, which will not be described in detail here. The second preset rotation angle and the clamping angle are determined by the rotation of the swinging block 44 and the setting position and the swinging angle of the clamping piece 45. Moreover, the contracted length of the second driving cylinder 42 in the vertical direction also determines the second preset rotation angle and the clamping angle at the same time.
