The adapter is used for transferring different jigs to the manipulator, and usually, a plurality of screws are used to fix the jigs to the adapter, and then the adapter is mounted to the manipulator, however, the screws need to be screwed down one by one, so that the mounting efficiency of the jigs is low.

Referring to fig. 1-3, in order to solve the problem of lower installation efficiency of the fixture, the application provides a fixture switching device. The clamp switching device comprises a switching seat 10 and a screwing fixer 20, wherein the screwing fixer 20 comprises a main body part 21 and a locking pin 22, the locking pin 22 is rotatably connected to the main body part 21, the switching seat 10 is provided with a plug hole 11, the locking pin 22 can be arranged in a penetrating manner of a clamp assembly and is inserted into the plug hole 11, so that the clamp assembly is clamped between the main body part 21 and the switching seat 10, one of the plug hole 11 and the locking pin 22 is provided with a rotation stopping convex part 111, the other one is provided with a rotation stopping groove 23 corresponding to the rotation stopping convex part 111, and when the locking pin 22 is in an initial position relative to the switching seat 10, the rotation stopping convex part 111 can slide into the rotation stopping groove 23 along a first preset direction so that the locking pin 22 is in a first preset position relative to the switching seat 10; when the locking pin 22 is at the first preset position relative to the adapter 10, the locking pin 22 can rotate clockwise or counterclockwise around the first preset direction by a first preset angle value relative to the adapter 10, so that the rotation stopping protrusion 111 and the rotation stopping groove 23 are in clamping fit along the first preset direction, the locking pin 22 is at the second preset position relative to the adapter 10, and the locking pin 22 is in locking fit with the adapter 10.

It should be noted that "the locking pin 22 is at the initial position relative to the adaptor 10" means that the locking pin 22 is inserted into the insertion hole 11, and the main body 21 is stopped at the natural state of the adaptor 10.

When the locking pin 22 is in an initial position relative to the adaptor 10, the main body 21 and the adaptor 10 cooperate to enable the clamp to be preliminarily clamped. Further, when the lock pin 22 is depressed so that the lock pin 22 moves toward the inside of the insertion hole 11, the rotation stopping protrusion 111 slides into the rotation stopping groove 23 in the first preset direction so that the lock pin 22 is switched from the initial position to the first preset position; then, when the locking pin 22 rotates clockwise or anticlockwise around the first preset direction by a first preset angle value relative to the adapter 10, the locking pin 22 is switched from the first preset position to the second preset position, and the locking pin 22 is in the second preset position so that the rotation stopping protruding portion 111 and the rotation stopping groove 23 are in clamping fit along the first preset direction, that is, the rotation stopping protruding portion 111 and the rotation stopping groove 23 are in stopping fit along the axis of the locking pin 22, at the moment, the locking pin 22 cannot be separated from the inserting hole 11, and therefore the locking pin 22 and the main body portion 21 are matched with a locking clamp assembly.

It will be appreciated that, by sliding the rotation stopping protrusion 111 along the rotation stopping groove 23, the locking pin 22 is switched from the first preset position to the second preset position, so that, to switch the locking pin 22 from the second preset position to the first preset position, only the locking pin 22 needs to be operated reversely, that is, the locking pin 22 rotates by a first preset angle value clockwise or clockwise around the first preset direction relative to the adaptor 10, and the unlocking of the locking pin 22 and the adaptor 10 can be achieved.

Therefore, the fixture assembly can be fixedly connected to the adaptor 10 only by interpolating the locking pin 22 in the plugging hole 11, then, rotating the locking pin 22 clockwise or anticlockwise around the first preset direction by a first preset angle value. The operation is very convenient, thereby remarkably improving the installation efficiency and the disassembly efficiency of the fixture assembly and the adapter 10.

In an embodiment, as shown in fig. 3, the rotation stopping groove 23 includes a communicating groove 231 and a clamping groove 232, the communicating groove 231 is disposed on the circumferential side of the locking pin 22 and extends along the first preset direction, one end of the communicating groove 231 is communicated with the clamping groove 232, and the other end penetrates through the end of the locking pin 22 far away from the main body 21 to form a clamping interface, so that the rotation stopping protrusion 111 can be clamped into the clamping groove 232 through the clamping interface and the communicating groove 231 in sequence; the axial direction of the locking pin 22 is the same as the first preset direction, one end of the clamping groove 232 is communicated with the communicating groove 231, and the other end extends around the axial direction of the locking pin 22, so that the rotation stopping protruding portion 111 and the inner wall of the clamping groove 232 can be clamped and matched along the first preset direction.

When the lock pin 22 is in the initial position with respect to the adapter 10, the rotation stopping protrusion 111 can be engaged into the engagement groove 232 through the engagement port from the end of the lock pin 22 remote from the main body 21, and by pressing down the lock pin 22, the rotation stopping protrusion 111 is moved upward with respect to the communication groove 231 to the communication position of the communication groove 231 and the engagement groove 232. Further, since the locking groove 232 extends around the first direction, when the rotation stopping protrusion 111 slides to the end of the locking groove 232, the locking protrusion can be in stop fit with the locking groove 232 along the first preset direction, and the locking protrusion can also be in locking fit with the locking groove 232 along the direction opposite to the extending direction of the locking groove 232.

Further, the rotation stopping groove 23 may be machined at the outer wall of the locking pin 22 by turning. The number of the rotation stopping grooves 23 may be one or a plurality, and when the number of the rotation stopping grooves 23 is a plurality, the plurality of rotation stopping grooves 23 are arranged at intervals around the first preset direction.

Specifically, in one embodiment, the engagement groove 232 communicates with the communication groove 231 at one end and extends 90 ° clockwise around the axial direction of the lock pin 22, where clockwise is seen straight from the main body portion toward the adapter. Thus, the screwing holder 20 is rotated 90 ° counterclockwise, and the switching from the first preset position to the second preset position can be achieved.

Further, as shown in fig. 3, the rotation stopping protrusion 111 is a ball, which is advantageous in reducing friction force of sliding engagement of the rotation stopping protrusion 111 with the rotation stopping groove 23.

In one embodiment, as shown in fig. 3, 4 and 5, the main body 21 is provided with a mounting through hole 211, the locking pin 22 is inserted into the mounting through hole 211, the screwing holder 20 further comprises an elastic compression member 24, the inner wall of the mounting through hole 211 is provided with a stop step 212, one end of the elastic compression member 24 is stopped at the locking pin 22, and the other end is stopped at the stop step 212, so that the locking pin 22 can compress the elastic compression member 24 when the rotation stopping protrusion 111 is along the first preset direction

Since the elastic compression member 24 is stopped at one end against the locking pin 22 and at the other end against the stopper step 212, when the rotation stopping protrusion 111 slides into the communication groove 231, that is, when the locking pin 22 is depressed such that the locking pin 22 moves downward with respect to the main body 21, the elastic compression member 24 can apply pressure to the locking pin 22 due to being compressed. Therefore, when the locking pin 22 is at the second preset position, such that the rotation stopping protrusion 111 is clamped in the clamping groove 232, the locking pin 22 is pressed by the elastic compression member 24 and does not rotate due to the false touch of the operator, so that the locking pin 22 can be prevented from being unlocked due to the false touch of the operator.

Specifically, the elastic compression member 24 may be a spring that is fitted around the outer periphery of the lock pin 22. The locking pin 22 comprises a pin shaft 221 and a screwing cap 222, the pin shaft 221 is fixedly connected with the screwing cap 222 through a fastening screw, an opening of the screwing cap 222 faces to the mounting through hole 211, one end of the spring is stopped at the screwing cap 222, and the other end of the spring is stopped at the stopping step 212.

Further, in one embodiment, as shown in fig. 3, the locking groove 232 has one end communicating with the communicating groove 231 and the other end extending spirally around the axial direction of the locking pin 22 and toward one end of the locking interface.

Since the engagement groove 232 extends in a spiral shape around the first preset direction toward the approaching body portion 21, when the rotation stopping protrusion 111 slides around the engagement groove 232, the lock pin 22 has a further downward movement stroke with respect to the body portion 21, and thus the distance between the screw cap 222 and the stop step 212 is further narrowed, so that the spring is further compressed. In this way, the pressure applied by the spring to the locking pin 22 is advantageously increased, so as to further increase the locking firmness of the locking pin 22 and the adaptor 10.

Of course, in other embodiments, the engaging groove 232 may have an arc shape extending axially around the locking pin 22.

Further, in an embodiment, as shown in fig. 2, the locking pin 22 is provided with a limiting protrusion 223, and when the locking pin 22 is locked and engaged with the adapter 10 at the second preset position, the limiting protrusion 223 stops at the opening of the plugging hole 11.
