The clamping structure 311 includes a seat 3113, a first chuck 3111 and a second chuck 3112. First chuck 3111 with second chuck 3112 sets up relatively and all connect in pedestal 3113. The first chuck 3111 and the second chuck 3112 are configured to cooperate to clamp the workpiece to be processed, that is, the first chuck 3111 and the second chuck 3112 cooperate to clamp the workpiece to be processed therebetween, thereby completing the clamping operation.

In summary, the clamping device 3 provided by the present application includes the clamping assembly 31 and the driving assembly 32, the first chuck 3111 and the second chuck 3112 in the clamping assembly 31 can cooperate to clamp the workpiece to be processed, and meanwhile, the clamping assembly 31 is connected to the driving assembly 32 and can be driven by the driving assembly 32, so that after the clamping assembly 31 finishes the process of clamping the workpiece to be processed, the workpiece can be driven by the driving assembly 32 to move, thereby achieving the purpose of moving to the target station, and further improving the production efficiency.

Referring to fig. 1 and 2, the clamping assembly 31 further includes a moving structure 312. The motion structure 312 includes a first substructure 3121 and a second substructure 3122. The first sub-structure 3121 and the second sub-structure 3122 are respectively connected to opposite ends of the clamping structure 311, and are used for carrying the clamping structure 311 to move on a carrying device 2 (which will be described later). It can be understood that the first substructure 3121 and the second substructure 3122 are installed at both ends of the clamping structure 311, so that the span of the clamping assembly 31 can be increased, thereby improving the motion stability of the clamping device 3 and ensuring that the workpiece to be processed is accurately transferred to the target station.

It should be noted that the driving assembly 32 may be directly connected to the moving structure 312, may also be directly connected to the holding structure 311, and may also be directly connected to both the moving structure 312 and the holding structure 311, which is not limited in this application.

Referring to fig. 1 and 2, the first substructure 3121 includes a first carrier support 3121a and a first traveling wheel 3121b connected. The first carrier 3121a is connected to the seat 3113.

The structure, connection and movement of the components of the clamping structure 311 are described in detail below.

At least one of the first chuck 3111 and the second chuck 3112 is movably connected to the base 3113, so that the first chuck 3111 and the second chuck 3112 can be relatively close to each other to clamp the workpiece to be machined.

The movable connection may be a rotating connection or a sliding connection, and the first chuck 3111 and the seat 3113 are exemplarily described below as being movably connected.

In one embodiment, the first chuck 3111 is slidably connected to the housing 3113, and the second chuck 3112 is fixedly connected to the housing 3113. In the process that the first chuck 3111 slides on the seat 3113, the first chuck 3111 gradually approaches the second chuck 3112 until the workpiece to be processed is clamped, and finally, the clamping operation is completed.

In another embodiment, the first chuck 3111 is rotatably connected to the housing 3113, and the second chuck 3112 is fixedly connected to the housing 3113. In the process that the first chuck 3111 rotates on the seat 3113, the first chuck 3111 gradually approaches the second chuck 3112 until the workpiece to be processed is clamped, and finally, the clamping operation is completed.

Wherein, at least one of the first chuck 3111 and the second chuck 3112 is movably connected to the holder body 3113, which means that only the first chuck 3111 is movably connected to the holder body 3113, or only the second chuck 3112 is movably connected to the holder body 3113, or both the first chuck 3111 and the second chuck 3112 are movably connected to the holder body 3113, which is described in detail below.

In one embodiment, the first chuck 3111 is movably connected to the base 3113, the second chuck 3112 is fixedly connected to the base 3113, and the clamping operation of the clamping structure 311 is implemented by the first chuck 3111 moving closer to the second chuck 3112.

In another embodiment, the first chuck 3111 is fixedly connected to the housing 3113, the second chuck 3112 is movably connected to the housing 3113, and the clamping operation of the clamping structure 311 is performed by the second chuck 3112 moving closer to the first chuck 3111.

In another embodiment, the first chuck 3111 and the second chuck 3112 are movably connected to the seat 3113, and the clamping operation of the clamping structure 311 is implemented by moving the first chuck 3111 and the second chuck 3112 toward each other, in other words, the first chuck 3111 moves toward the second chuck 3112, and the second chuck 3112 moves toward the first chuck 3111.

It should be noted that the above embodiments can be combined without contradiction, and only one of them will be specifically described below because many possible embodiments are possible.

Referring to fig. 3, the first chuck 3111 is rotatably connected to the seat body 3113, and the first chuck 3111 can be rotatably connected to the seat body 3113 through a shaft segment 3114 connected to the seat body 3113. The second chuck 3112 is fixedly connected to the seat 3113. The first chuck 3111 has a first holding end a1 for holding a member to be machined, and the second chuck 3112 has a second holding end a2 for holding a member to be machined. The clamping device 3 has a clamped state and an unclamped state, and the distance between the first clamping end A1 and the second clamping end A2 is a first distance when the clamping device 3 is in the clamped state. When the clamping device 3 is in the non-clamping state, the distance between the first clamping end A1 and the second clamping end A2 is a second distance, and the first distance is smaller than the second distance.

Referring to fig. 4, the clamping structure 311 further includes a force-applying member 3115 supported on the seat body 3113. The force applying member 3115 is connected to the first chuck 3111. The force applying member 3115 is configured to drive the first chuck 3111 to rotate, so that the first clamping end a1 of the first chuck 3111 is close to the second clamping end a2 of the second chuck 3112.

In one embodiment, the force applying member 3115 can be a motor, and the motor is carried by the seat body 3113. The motor has a rotatable output shaft, the output shaft is connected to the first chuck 3111, the first chuck 3111 can rotate along with the output shaft, so that the first clamping end a1 of the first chuck 3111 and the second clamping end a2 of the second chuck 3112 can approach each other relatively to complete the clamping operation.

In another embodiment, as shown in fig. 4, the force applying member 3115 may be a piston, and the piston abuts against the other end of the first chuck 3111 away from the first clamping end a1 and drives the other end so that the first clamping end a1 of the first chuck 3111 approaches the second clamping end a2 of the second chuck 3112. Specifically, the first chuck 3111 is rotatably connected to the seat 3113 through a shaft section 3114. The holder body 3113 has a receiving cavity B1 and a through hole B2. The urging member 3115 is housed in the housing cavity B1. The through hole B2 communicates with the receiving chamber B1 and serves to introduce fluid into the receiving chamber B1. The part of the first chuck 3111 far from the first clamping end a1 is accommodated in the accommodating cavity B1 and connected to the force applying member 3115. The force applying part 3115 is configured to move in the accommodating cavity B1 under the action of the fluid and drive the first chuck 3111 to rotate, so that an end of the first chuck 3111 away from the force applying part 3115 is close to the second chuck 3112. In other words, when the fluid is introduced into the receiving cavity B1, the pressure in the receiving cavity B1 continuously rises, so as to urge the piston to move to press the portion of the first chuck 3111 away from the first clamping end a1, so that the first chuck 3111 rotates, and the first clamping end a1 gradually draws close to the second clamping end a2 of the second chuck 3112 during the rotation, thereby finally realizing the clamping operation. The fluid may be a gas (pneumatically driven) or a liquid (hydraulically driven), and is not limited herein.

Of course, other possible implementations exist and are not described in detail herein.

Referring to fig. 4, the clamping structure 311 further includes an elastic member 3116. The elastic member 3116 may be, but is not limited to, a spring. The two opposite ends of the elastic member 3116 are respectively abutted against the first chuck 3111 and the seat 3113. The elastic member 3116 is used for providing an elastic force to the first chuck 3111 in a direction away from the second chuck 3112, that is, when the clamping device 3 is in the clamping state, the elastic member 3116 is in a compressed state, and the elastic member 3116 is used for providing a force to the clamping device 3 to be converted from the clamping state to the non-clamping state. Specifically, after the holding device 3 holds the workpiece to be processed to the target station, the workpiece to be processed needs to be released, and at this time, the first chuck 3111 and the second chuck 3112 need to be loosened. The specific realization principle is as follows: the fluid pressure in the receiving cavity B1 is reduced, so that the torque applied by the elastic member 3116 to the first chuck 3111 is greater than the torque applied by the force applying member 3115 to the first chuck 3111, and the first chuck 3111 rotates reversely, i.e. the first clamping end a1 of the first chuck 3111 moves away from the second clamping end a2 of the second chuck 3112, thereby releasing the workpiece to be processed.

It can be understood that the elastic member 3116 can force the first clamping end a1 of the first clamping head 3111 and the second clamping end a2 of the second clamping head 3112 to open at a larger angle, that is, the space between the first clamping end a1 and the second clamping end a2 is larger, and the larger space is beneficial for clamping the workpiece to be machined next time.

Referring to fig. 4, the first chuck 3111 has a first groove B3. The holder body 3113 is provided with a second groove B4, and the first groove B3 and the second groove B4 are oppositely arranged. The elastic member 3116 is disposed in the first groove B3 and the second groove B4. The shape of the first groove B3 and the second groove B4 may be, but not limited to, a circular groove, an oval groove, etc., and is determined by the shape of the elastic member 3116. It can be understood that the elastic member 3116 is disposed in the first groove B3 and the second groove B4, so that the elastic member 3116 is ensured not to fall off from the clamping device 3 during the telescoping process, which is beneficial to the continuous clamping operation.

Referring to fig. 3, the housing 3113 has a mounting hole B5, the mounting hole B5 can be inserted with a connecting member (such as a bolt), and the first sub-structure 3121 and the second sub-structure 3122 can be fixedly connected to the housing 3113 by one or more connecting members.

Optionally, the number of the mounting holes B5 is multiple, where multiple means the number is greater than or equal to two, and specifically, but not limited to, 2, 3, 5, etc. The first and second sub-structures 3121, 3122 may be secured to the housing 3113 by any one of a plurality of mounting holes B5. It will be appreciated that a plurality of mounting holes B5 are provided so that the relative position of the housing 3113 and the moving structure 312 can be adjusted. Further optionally, the arrangement direction of the plurality of mounting holes B5 is parallel to the direction in which the first chuck 3111 points to the second chuck 3112, that is, the plurality of mounting holes B5 are disposed on different heights of the holder body 3113, so as to be adapted to hold workpieces to be processed at different height positions.

Optionally, the mounting holes B5 penetrate through two opposite sides of the seat body 3113, and the first substructure 3121 and the second substructure 3122 share one mounting hole B5, that is, one mounting hole B5 may achieve fixing the first substructure 3121 and the second substructure 3122 at the same time, so that the number of holes formed in the mounting hole B5 may be reduced, and thus the hole forming time may be reduced.

Referring to fig. 5 and 6, the present application further provides a feeding device 1, where the feeding device 1 includes a carrying device 2 and a clamping device 3 described in any of the above embodiments. The carrying device 2 includes a bracket 21 and a carrying plate 22. The bearing plate 22 is supported by the bracket 21. The carrying plate 22 is used for carrying the holding device 3, and the holding device 3 can move on the carrying plate 22 through the first traveling wheel 3121b and the second traveling wheel 3122b to convey the workpiece to be processed. The specific structure of the clamping device 3 refers to the drawings in the previous embodiments and the corresponding description.

The carrier 22 includes a first carrier 221 and a second carrier 222. The first bearing plate 221 is used for bearing the first substructure 3121 of the clamping device 3. The second carrier plate 222 is used to carry the second substructure 3122 of the holding device 3.

Further, the first carrier plate 221 and the second carrier plate 222 are disposed at an interval to form an interval space B6. The second collet 3112 of the holding device 3 is at least partially accommodated in the space B6. It will be appreciated that during the movement of the holding device 3 holding the workpiece to be processed on the carrier plate 22, it is necessary to ensure that the movement of the holding device 3 cannot deviate from the target path, which could result in the workpiece not being accurately transferred to the target station. In the present embodiment, the second chuck 3112 of the clamping device 3 is at least partially received in the space B6 formed by the first carrier plate 221 and the second carrier plate 222, so that the movement of the second chuck 3112 can be limited by the first carrier plate 221 and the second carrier plate 222, and the purpose of preventing the clamping device 3 from deviating from the target path is achieved, thereby ensuring that the workpiece to be processed is accurately transferred to the target station.

Although embodiments of the present application have been shown and described, it is understood that the above embodiments are illustrative and not restrictive, and that those skilled in the art may make changes, modifications, substitutions and alterations to the above embodiments without departing from the scope of the present application, and that such changes and modifications are also to be considered as within the scope of the present application.
