Description

Technical Field

[0001] This invention belongs to the field of clamping tooling technology, and particularly relates to an integrated clamping and rotating device. Background Technology

[0002] Clamping mechanisms are widely used in the manufacturing industry, such as in precision electronic equipment, communication equipment, medical equipment, automotive, and aerospace. In some fields, it is not only necessary to clamp products but also to ensure their protection, i.e., to achieve non-destructive clamping. Examples include the gripping of camera modules (sapphire glass lenses), ceramic capacitors and resistors, and small flexible components; the auxiliary gripping and transport of ceramic ferrules, optical lenses, and fiber optic cables; and in the medical equipment field, the gripping and transport of cuvettes, sampling needles, reaction cups, disposable plastic products, and PCR tubes.

[0003] Therefore, in modern manufacturing, how to achieve non-destructive clamping and rotary drive of products is a technical problem that needs to be further overcome. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this application proposes a clamping and rotating integrated device, the specific technical solution of which is as follows: A clamping and rotating integrated device, comprising: A rotating shaft, one end of which is provided with a gripper feed guide block, and the gripper feed guide block is provided with a plurality of irregularly shaped grippers that can move radially along the rotating shaft; A cam guide groove module is connected to a rotary power source and is coaxially disposed on the outside of a rotating shaft. The cam guide groove module is provided with a guide groove, and a wear-resistant follower wheel is connected to the irregular-shaped gripper. The wear-resistant follower wheel is located inside the guide groove. The spring support block is fixed to the rotating shaft, and a swingable damping block is connected to the spring support block. The damping block can swing to change the relative fixed state between the cam guide groove module and the rotating shaft to a relative rotating state. When the damping block causes the cam guide groove module to rotate relative to the rotating shaft, the cam guide groove module rotates to open and close the irregular gripper to clamp the item; when the damping block causes the cam guide groove module to be fixed relative to the rotating shaft, the power source can drive the item on the irregular gripper to rotate.

[0005] In one embodiment, the cam guide groove module is coaxially fixed to the reducer rotor via a cam guide groove module adapter plate and a reducer rotor adapter seat, and the reducer is connected to the output end of the servo motor.

[0006] In one embodiment, a double-row angular contact ball bearing is installed in the reducer rotor adapter, and the rotating shaft extends into the reducer rotor adapter and is fixed to the inner ring of the double-row angular contact ball bearing.

[0007] In one embodiment, the damping block is rotatably connected to the spring support block via a damping hinge, and the spring support block is also provided with a damping spring, which presses the damping block against the cam guide groove module adapter plate.

[0008] In one embodiment, it further includes a fixedly installed pneumatic slide and a fork plate fixed to the telescopic end of the pneumatic slide. When the damping block rotates to the position corresponding to the fork plate, the pneumatic slide can drive the fork plate to extend and push the damping block to separate from the guide groove module adapter plate.

[0009] In one embodiment, the device further includes a top-feed probe, which is coaxially arranged with the rotating shaft. The rotating shaft has a through hole extending axially through its center, allowing the top-feed probe to pass through the center of the rotating shaft to the space between the irregularly shaped grippers.

[0010] In one embodiment, the top material probe is fixed to the moving end of the pneumatic slide.

[0011] The beneficial effects of this invention are as follows: The clamping and rotating integrated device of this application uses a servo motor and reducer as the main power for the clamping and rotating module, and the auxiliary limit and limit mechanism consists of a pneumatic slide and a spring damping module; its gripper adopts a multi-lobed gripper, combined with a cam guide groove and a wear-resistant follower wheel, which can achieve non-destructive clamping of parts while driving the parts to rotate infinitely.

Detailed Implementation

[0013] In the following description, certain specific details are set forth in order to provide a thorough understanding of various embodiments. However, those skilled in the art will understand that the invention can be practiced without these details. In other instances, well-known structures have not been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments. Unless the context otherwise requires, throughout the specification and appended claims, the word "comprising" should be interpreted in an open-ended, inclusive sense, i.e., as "including but not limited to".

[0014] Figure 1 The figure shown is an assembly diagram of the clamping and rotating integrated device of this application. Figure 2 The diagram shown is an exploded view of the clamping and rotating integrated device of this application. The clamping and rotating integrated device of this application is mainly used in scenarios of non-destructive clamping and infinite rotation, and can realize the clamping, transfer and infinite rotation of micro-elastic, non-stressable, fragile and easily deformable parts.

[0015] See Figure 1 The integrated clamping and rotating device includes a module base plate 12 for fixing and mounting other components. The module base plate 12 is equipped with a rotary drive component, a non-destructive clamping execution component 9, and a conversion component. The rotary drive component is mounted on the module base plate 12 to provide a rotary power source. The non-destructive clamping execution component 9 clamps or releases the product according to the rotary power source provided by the rotary drive component. The conversion component is used to change the connection method between the non-destructive clamping execution component 9 and the rotary drive component.

[0016] The rotary drive component includes a servo motor 4, the output end of which is connected to a reducer. The reducer has a reducer rotor 14 as its output end and a reducer mounting base 8. The reducer is fixedly connected to the reducer mounting plate 11 via the reducer mounting base 8. The reducer mounting plate 11 is vertically fixed on the module base plate.

[0017] The non-destructive clamping actuator 9 includes a reducer rotor adapter 115, a double-row angular contact ball bearing 114, a cam guide groove module adapter plate 113, a rotating shaft 110, a cam guide groove module 106, a shaped gripper 6-105, a wear-resistant follower wheel 6-103, a follower wheel limit nut 6-104, a gripper feed guide block 102, and a gripper upper cover plate 101.

[0018] The reducer rotor adapter 115 is coaxially fixed with the reducer rotor 14, and the cam guide groove module 106 is coaxially fixed with the reducer rotor adapter 115 through the cam guide groove module adapter plate 113. The reducer rotor 14 can drive the cam guide groove module 106 to rotate synchronously.

[0019] On the other hand, a gripper feed guide block 102 is provided at one end of the rotating shaft 110. The irregular grippers 6-105 are arranged in a ring on the gripper feed guide block 102, and the irregular grippers 6-105 can move radially along the gripper feed guide block 102. A gripper cover plate 101 is provided on the end face of the gripper feed guide block 102 to fix the irregular grippers 6-105 to the gripper feed guide block 102. The rotating shaft 110 and the cam guide groove module 106 are coaxially arranged, and the rotating shaft 110 and the cam guide groove module 106 can rotate relative to each other. The other end of the rotating shaft 110 is fixed to a double row angular contact ball bearing 114, which is coaxially fixed in the reducer rotor adapter seat 115.

[0020] The cam guide groove module 106 is provided with a guide groove. A wear-resistant follower wheel 6-103 is fixed to the irregular-shaped gripper 6-105 by a follower wheel limiting nut 6-104. The wear-resistant follower wheel 6-103 is located in the guide groove of the cam guide groove module 106. When the cam guide groove module 106 is fixed, rotating the rotating shaft 110 causes the rotating shaft 110 to drive the gripper feed guide block 102 and the irregular-shaped gripper 6-105 to rotate synchronously. The wear-resistant follower wheel 6-103 is aligned with the guide groove. When closed, the irregular-shaped gripper 6-105 rotates while moving axially along the gripper feed guide block 102, thereby causing the irregular-shaped gripper 6-105 to open or close; or, when the rotating shaft 110 is fixed, after the reducer rotor 14 drives the cam guide groove module 106 to rotate, the wear-resistant follower wheel 6-103 cooperates with the guide groove to drive the irregular-shaped gripper 6-105 to rotate while moving axially along the gripper feed guide block 102, thereby causing the irregular-shaped gripper 6-105 to open or close.

[0021] In conjunction with the foregoing, the reducer rotor adapter 115, the cam guide groove module 106 and the cam guide groove module adapter plate 113 form a rotating body, while the rotating shaft 110, the gripper feed guide block 102 and the irregular grippers 6-105 form another rotating body. The two rotating bodies can rotate relative to each other, and the conversion component is used to control the relative rotation state of the two rotating bodies.

[0022] The conversion component includes a spring support block 108, a damping hinge 112, a damping block 109, and a damping spring 107. The spring support block 108 is fixedly connected to the rotating shaft 110. The damping hinge 112 rotatably connects the damping block 109 to the spring support block 108. The damping spring 107 is disposed between the spring support block 108 and the damping block 109. The damping spring 107 applies an elastic force to the damping block 109, causing the damping block 109 to press against the cam guide groove module adapter plate 113. Through the friction between the damping block 109 and the cam guide groove module adapter plate 113, the rotating shaft 110 and the reducer rotor adapter seat 115 can be kept relatively fixed. When the damping block 109 is subjected to force and moves away from the cam guide groove module adapter plate 113, the rotating shaft 110 can then rotate relative to the reducer rotor adapter seat 115.

[0023] See Figure 3 The cam guide groove module 106 has a notch to facilitate the installation of the spring support block 108 and to connect the spring support block 108 to the rotating shaft 110.

[0024] Combination Figure 1 and Figure 2 A pneumatic slide plate 15 is also fixedly connected to the reducer mounting plate 11. A pneumatic slide 5 is installed on the pneumatic slide plate 15. The telescopic end of the pneumatic slide 5 is connected to the fork plate mounting block 6. A fork plate 7 is fixed on the fork plate mounting block 6. When the damping block 109 rotates to the position corresponding to the fork plate 7, the pneumatic slide 5 drives the fork plate 7 to move towards the damping block 109 until the damping block 109 is separated from the cam guide groove module adapter plate 113 under the thrust of the fork plate 7. While the fork plate 7 pushes out the damping block 109, it also limits the damping block 109, the spring support block 108, the rotating shaft 110 and the gripper feed guide block 102, restricting the rotation of these components.

[0025] Based on the above description, the working method of the clamping and rotating integrated device of this application is as follows: the damping block 109 is rotated to correspond to the position of the fork plate 7, and the pneumatic slide 5 is controlled to drive the fork plate mounting block 6 and the fork plate 7 to push the damping block 109 forward. Under the action of the thrust, the damping block 109 separates from the cam guide groove module adapter plate 113. While the fork plate 7 pushes out the damping block 109, it also limits and fixes the damping block 109, spring support block 108, rotating shaft 110, and gripper feed guide block 102, keeping them stationary; at the same time, the servo motor 4 The rotation of the reducer rotor 14, reducer rotor adapter 115, double-row angular contact ball bearing 114, cam guide groove module adapter plate 113, and cam guide groove module 106 causes the wear-resistant follower wheel 6-103 and follower wheel limit nut 104 to rotate under the action of the guide groove of the cam guide groove module 106. Simultaneously, this drives the irregularly shaped gripper 6-105 to move. Following the guide groove trajectory of the cam guide groove module 106, the irregularly shaped gripper 6-105 opens and closes, forming the gripper clamping dimensions. The size can be controlled by adjusting the rotation angle of the servo motor 4. After the irregularly shaped grippers 6-105 enclose the product, the servo motor 4 rotates in the opposite direction, slowly closing the grippers 6-105 until they are within the tolerance range of the product size and the product is securely clamped. The servo motor 4 then stops rotating. Then, the pneumatic slide 5 drives the fork plate mounting block 6 and the fork plate 7 to retract. The damping block 109, under the elastic force of the damping spring 107, presses against the cam guide groove module adapter plate 113. At this point, the rotating shaft 110 and the gripper feed guide block 102... The wear-resistant follower wheel 6-103, follower wheel limit nut 104, irregular-shaped gripper 6-105, cam guide groove module 106, damping spring 107, spring support block 108, damping block 109, cam guide groove module adapter plate 113, reducer rotor 14, reducer rotor adapter seat 115 and other auxiliary clamping parts are relatively fixed, and their clamping dimensions are also fixed. The non-destructive clamping execution component 9 forms a fixed whole. At this time, the servo motor 4 drives the reducer rotor 14 and the non-destructive clamping execution component 9 to rotate infinitely.

[0026] In addition, combined Figure 1 and Figure 2 A pneumatic slide mounting plate 1 is fixedly installed on the module base plate 12. A top-feeding pneumatic slide 2 is installed on the pneumatic slide mounting plate 1. The top-feeding pneumatic slide 2 is connected to the top-feeding probe 10 through the ejector pin mounting plate 3. The top-feeding probe 10 is coaxial with the rotating shaft 110. The rotating shaft 110 and the gripper feed guide block 102 are hollow structures, so that the top-feeding probe 10 can extend into the rotating shaft 110. By driving the top-feeding pneumatic slide 2 to extend into and pass through the rotating shaft 110, the product held in the center by the irregular gripper 6-105 can be ejected.

[0027] The top material pneumatic slide 2 is also equipped with a pin limit block 13, which is used to control the moving distance of the top material probe 10.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
