[0025] 1. Since the connecting assembly is movably arranged on the base assembly, and the base assembly is provided with a connecting groove, the connecting assembly is provided with a connecting hole, and a reset member is provided between the connecting assembly and the base assembly. Therefore, when the chuck needs to be installed, the connecting assembly is first moved so that the connecting hole on the connecting assembly is aligned with the corresponding connecting groove on the base assembly. The connecting hole and the connecting groove cooperate to form an installation channel. At this time, the reset member deforms under the action of external force; then the connecting column is connected and placed in the installation channel; thereafter, the connecting assembly is no longer moved, and the reset member is no longer subjected to force and begins to restore its original state. During this process, the reset member drives the connecting assembly to move again, causing the connecting assembly and the base assembly to be misaligned, that is, the connecting hole and the connecting groove are misaligned, so that the connecting column set in the installation channel is clamped, thereby achieving the purpose of quickly installing the chuck. When the chuck needs to be maintained or replaced, the connecting assembly is moved again to align the connecting hole with the corresponding connecting groove to release the limit on the connecting column, and the current chuck can be removed. During the entire process, the chuck can be disassembled and assembled only by moving the connecting components, which not only ensures the connection effect and connection stability after the chuck is installed, but also improves the convenience and work efficiency when disassembling and assembling the chuck; at the same time, no other connecting parts such as screws are required during the entire process, so the occurrence of situations such as the loss of parts can be completely avoided.

[0026] 2. Because the load-bearing device includes a chuck, the collet on the chuck can be quickly replaced when different parts need to be loaded to meet the clamping requirements of different parts. Throughout the process, while ensuring the loading effect of different parts, the operating efficiency of the load-bearing device is improved, and the application range of the chuck and load-bearing device is expanded.

[0044] Combine Figures 1 to 4 As shown, the chuck provided in this embodiment is used to clamp parts for subsequent processing, and the chuck 100 can be replaced to clamp different parts. Specifically, the chuck includes a chuck 100, a base assembly 200, a connecting assembly, and a reset member 400. The chuck 100 is provided with a connecting column 110; the base assembly 200 is provided with a connecting groove 201; the connecting assembly is movably connected to the base assembly 200, and a connecting hole 301 is provided on the connecting assembly. When the connecting assembly is moved so that the connecting hole 301 is aligned with the connecting groove 201, the connecting hole 301 and the connecting groove 201 cooperate to form an installation channel, so that the connecting column 110 can be accommodated in the installation channel; the reset member 400 is accommodated between the base assembly 200 and the connecting assembly. After the connecting column 110 is connected to the installation channel, the reset member 400 drives the connecting assembly and the base assembly 200 to be displaced to clamp the connecting column 110.

[0045] Since the connecting assembly is movably arranged on the base assembly 200, and the base assembly 200 is provided with a connecting groove 201, the connecting assembly is provided with a connecting hole 301, and a reset member 400 is provided between the connecting assembly and the base assembly 200. Therefore, when the chuck 100 needs to be installed, the connecting assembly is first moved so that the connecting hole 301 on the connecting assembly is aligned with the corresponding connecting groove 201 on the base assembly 200, and the connecting hole 301 and the connecting groove 201 cooperate to form an installation channel. At this time, the reset member 400 is deformed under the action of external force; then the connecting column 110 is placed in the installation channel; thereafter, the connecting assembly is no longer moved, and the reset member 400 is no longer subjected to force and begins to restore its original state. In this process, the reset member 400 drives the connecting assembly to move again, so that the connecting assembly and the base assembly 200 are misaligned, that is, the connecting hole 301 and the connecting groove 201 are misaligned, so that the connecting column 110 set in the installation channel is clamped, thereby achieving the purpose of quickly installing the chuck 100. When the chuck 100 needs to be maintained or replaced, the connecting assembly is moved again to align the connecting hole 301 with the corresponding connecting groove 201 to release the limit on the connecting column 110, and the current chuck 100 can be removed. Throughout the entire process, only the connecting assembly needs to be moved to complete the disassembly and assembly of the chuck 100. While ensuring the connection effect and connection stability of the chuck 100 after installation, it also improves the convenience and work efficiency during disassembly and assembly of the chuck 100. At the same time, no other connecting parts such as screws are required during the entire process, thus completely avoiding the occurrence of parts loss.

[0046] Preferably, the base assembly 200 includes a chuck base 210 and a connecting base 220 connected to the chuck base 210. The connecting base 220 is configured as a columnar shape, and a mounting groove 202 is provided on the upper end surface of the connecting base 220 along its axial direction. The connecting groove 201 is provided on the bottom wall of the mounting groove 202. The connecting assembly includes a first connecting member 310 in the shape of an elongated strip, and a connecting hole 301 is provided in the first connecting member 310. The first connecting member 310 is movably connected to the mounting groove 202, and the reset member 400 is provided between the first connecting member 310 and the connecting base 220. In this embodiment, the cross-section of the chuck base 210 in the axial direction is configured as a circle. The first connecting member 310 is provided radially along the chuck base 210. By pressing the first connecting member 310, the chuck 100 is connected to the mounting channel, and the connection strength and stability are ensured.

[0047] Among them, the specific structure and operating principle of the base assembly 200 are as follows: the chuck base 210 is composed of a connecting part 211 and a rotating part 212, the rotating part 212 is arranged in a ring shape, and the connecting part 211 is provided with a connecting shaft, which passes through the rotating part 212 and is connected to the output shaft of the power assembly 500; the connecting seat 220 is connected to the connecting part 211, and the end face of the connecting seat 220 close to the rotating part 212 is provided with a plurality of first transmission teeth (not shown in the figure), and the plurality of first transmission teeth are arranged at intervals along the length direction of the connecting seat 220; the rotating part 212 is provided with second transmission teeth 2121 corresponding to the plurality of first transmission teeth, and the second transmission teeth 2121 are arranged in a threaded ring shape, and the first transmission teeth are engaged with the second transmission teeth 2121. Assuming that the gap between the first first transmission tooth and the second first transmission tooth is engaged with the second transmission tooth 2121 as the initial position, when it is necessary to change the relative position between the connecting seat 220 and the base assembly 200, the output shaft of the power assembly 500 drives the connecting part 211, thereby driving the three connecting seats 220 to rotate. At this time, the rotating part 212 is twisted in the opposite direction of the rotation of the connecting part 211, so that the rotating part 212 and the connecting part 211 rotate relative to each other, so that the gap between the second first transmission tooth and the third first transmission tooth is engaged with the second transmission tooth 2121, thereby achieving the centripetal movement of the corresponding connecting seat 220 to change the relative position between the connecting seat 220 and the base assembly 200.

[0048] Specifically, a pressing portion 311 is provided at the first end of the first connecting member 310, and the reset member 400 is provided as a spring; the spring is provided between the pressing portion 311 and the first end of the connecting seat 220, and / or the spring is provided between the second end of the first connecting member 310 and the second end of the connecting seat 220.

[0049] When the spring is set as a compression spring, the spring is set between the pressing part 311 and the first end of the connecting seat 220. When the first connecting member 310 is pressed, the compression spring is compressed by the external force. When the connecting column 110 is connected to the installation channel and the first connecting member 310 is no longer pressed, the compression spring rebounds to drive the first connecting member 310 to move toward the center of the back chuck base 210, so that the connecting hole 301 and the corresponding clamping groove 111 are misaligned, thereby clamping the corresponding connecting column 110 to complete the installation of the chuck 100. When the spring is configured as a tension spring, the spring is disposed between the second end of the first connector 310 and the second end of the connector base 220. When the first connector 310 is pressed, the tension spring is stretched by an external force. When the connecting post 110 is connected to the installation channel and the first connector 310 is no longer pressed, the tension spring retracts to drive the first connector 310 toward the center of the back chuck base 210, so that the connecting hole 301 and the corresponding engaging groove 111 are misaligned, thereby clamping the corresponding connecting post 110 and completing the installation of the chuck 100. In this embodiment, the spring is configured as a compression spring and is disposed between the pressing portion 311 and the first end of the connector base 220. In addition, the pressing portion 311 facilitates the operator in pressing the first connector 310, and during the pressing process, interference with other components can be avoided.

[0050] In some other embodiments, the reset member 400 may also be configured as an elastic part such as a spring.

[0051] Preferably, a limiting portion is provided between the first connecting member 310 and the mounting groove 202 to limit the relative position of the first connecting member 310 and the connecting seat 220 .

[0052] In this embodiment, the limiting portion is provided in two aspects: first, an elongated hole extending along the length of the first connecting member 310 is provided on the first connecting member 310, and a limiting post is provided on the bottom wall of the mounting groove 202. When the first connecting member 310 is connected to the mounting groove 202, the limiting post and the elongated hole cooperate to prevent the first connecting member 310 from being over-pressed and to prevent the first connecting member 310 and the corresponding connecting seat 220 from being separated from each other along the length of the first connecting member 310. Alternatively, an elongated hole extending along the length of the mounting groove 202 is provided on the bottom wall of the mounting groove 202, and a limiting post is provided on the first connecting member 310. The second aspect: from the bottom of the installation groove 202 to the direction of the open end of the wallpaper installation groove 202, the width of the installation groove 202 gradually decreases, that is, the axial cross-sectional shape of the installation groove 202 is set to a trapezoidal or dovetail groove shape, and the cross-sectional shape of the first connecting member 310 is set corresponding to the installation groove 202. The first connecting member 310 cooperates with the corresponding installation groove 202, and limits the relative position between the first connecting member 310 and the corresponding connecting seat 220 in the depth direction of the installation groove 202, thereby ensuring the connection effect of the corresponding chuck 100.

[0053] In order to further improve the connection strength and connection stability after the connecting column 110 is connected to the installation channel, in this embodiment, a snap-in groove 111 is provided on the connecting column 110, and the snap-in groove 111 extends circumferentially along the connecting column 110 in a ring shape. The width of the snap-in groove 111 is equal to the thickness of the first connecting member 310. When the connecting column 110 is connected to the installation channel and the first connecting member 310 is no longer bent, the spring recovers autonomously and drives the first connecting member 310 to move, so that the snap-in portion 3012 on the first connecting member 310 is snap-fitted with the corresponding snap-in groove 111, thereby limiting the relative position between the connecting column 110 and the installation channel in the axial direction of the connecting column 110.

[0054] To further expand the chuck's applicability, the chuck head 100 in this embodiment is designed in a stepped, flat, or cylindrical shape. It connects to the mounting channel via a connecting post 110. When different parts need to be clamped, a different chuck head 100 can be replaced without replacing the entire chuck. This ensures effective clamping while expanding the chuck's applicability.

[0055] Preferably, the chuck further comprises a sensing member and a prompting member, wherein the sensing member is used to sense the position of the connecting column 110 and is inductively connected to the prompting member. The sensing member is provided on the base assembly 200 and / or the connecting assembly and / or the reset member 400. When the connecting column 110 is connected to the installation channel, the reset member 400 is deformed. At this time, the sensing member senses the presence of the connecting column 110 in the installation channel, or senses the deformation of the reset member 400, and sends an installation signal to the prompt member. After receiving the installation signal, the prompt member sends a first prompt. When the installation column is removed from the installation channel, the reset member 400 returns to its original state. The sensing member cannot sense the connecting column 110, or senses that the reset member 400 has returned to its original state, and sends a vacancy signal to the prompt member. After receiving the vacancy signal, the prompt member sends a second prompt. When the connecting column 110 is connected to the installation channel, but the connecting column 110 shakes, the deformation of the reset member 400 changes. After sensing the change of the reset member 400, the sensing member sends a prompt signal to the prompt member. The prompt member sends a second prompt, so that the operator can adjust the connection status of the current connecting column 110 in time, thereby ensuring the subsequent processing and use effect. According to actual needs, the first prompt, second prompt, and third prompt can all be implemented using lights of different colors and / or sounds with different sound effects.

[0056] Preferably, a plurality of connecting grooves 201 are arranged at intervals on the base assembly 200, and a plurality of connecting holes 301 are correspondingly arranged; the connecting holes 301 are arranged as a mounting portion 3011 and a clamping portion 3012 that are interconnected, and the mounting portion 3011 and the clamping portion 3012 are both semicircular, the diameter of the mounting portion 3011 is larger than the diameter of the connecting column 110, and the size of the clamping portion 3012 is less than or equal to the diameter of the connecting column 110.

[0057] In this embodiment, there are twelve connecting grooves 201 and three connecting seats 220. Four connecting grooves 201 are arranged on each connecting seat 220 along the length direction of the connecting seat 220. The three connecting seats 220 are evenly spaced and connected to the chuck base 210 along the circumference of the chuck base 210. Correspondingly, there are three first connecting members 310, each of which is correspondingly provided with four connecting holes 301. The three first connecting members 310 are movably connected to the three connecting seats 220 in a one-to-one correspondence. A reset member 400 is provided between each first connecting member 310 and the corresponding connecting seat 220. In this embodiment, three chucks 100 are provided corresponding to the connecting seats 220. The three chucks 100 cooperate with each other to form a clamping space to clamp the corresponding parts. Specifically, after the parts are placed in the clamping space, the three connecting seats 220 begin to move centripetally under the cooperation of the connecting portion 211 and the rotating portion 212, so as to drive the three chucks 100 to clamp the parts in the clamping space. By changing the relative position between the chuck 100 and the corresponding connecting seat 220, the size of the clamping space is changed, so as to achieve the technical effect of clamping parts with different diameter ranges with the same chuck.

[0058] In addition, in the present embodiment, the side of each connecting hole 301 close to the pressing portion 311 is set as the mounting portion 3011, and the side away from the pressing portion 311 is set as the clamping portion 3012; when installing the connecting column 110, the pressing portion 311 is pressed, the spring is compressed, and the mounting portion 3011 is concentric with the corresponding connecting groove 201 to form a mounting channel; after the connecting column 110 is installed in the mounting channel, the first connecting member 310 is no longer pressed, and the spring rebounds automatically after being no longer under pressure, driving the first connecting member 310 to move in a direction away from the center of the chuck base 210, so that the clamping portion 3012 is concentric with the corresponding connecting groove 201, and is clamped with the clamping groove 111 on the corresponding connecting column 110, so as to limit and ensure the connection strength and connection stability of the connecting column 110.

[0059] In some other embodiments, the base assembly 200 includes a chuck base 210 and a connecting seat 220 connected to the chuck base 210, the chuck base 210 is configured to be disc-shaped, the connecting groove 201 is configured to be on the connecting seat 220, the connecting assembly includes a second connecting member (not shown in the figure) in the shape of a disc, and the connecting hole 301 is configured to be on the second connecting member; the second connecting member is rotatably disposed on the chuck base 210, the reset member 400 is configured to be a spring, the spring is configured to be between the second connecting member and the connecting seat 220, and extends along the circumference of the second connecting member.

[0060] Specifically, the chuck base 210 and the second connecting member are both configured in a disc shape. The second connecting member is rotatably connected to the chuck base 210 and is concentrically arranged with the chuck. At least one spring is provided between the chuck base 210 and the second connecting member, and the spring can be configured as a tension spring or a compression spring. When installing the connecting column 110, the second connecting member is rotated clockwise or counterclockwise so that the second connecting member cooperates with the connecting seat 220 to form an installation channel, and the tension spring or the compression spring deforms along the circumference of the chuck base 210. After the connecting column 110 is installed in the installation channel, the second connecting member is no longer rotated, and the second connecting member clamps the connecting column 110 under the drive of the tension spring or the compression spring. In addition, in order to ensure the effectiveness of the spring, a guide limit groove is provided on the chuck base 210 or the second connecting member. The spring is provided in the guide limit groove, and its two ends are respectively connected to the chuck base 210 and the second connecting member.

[0061] Combine Figure 5 As shown, the carrying device provided in this embodiment includes a power assembly 500 , a frame 600 and a chuck. The power assembly 500 is installed on the frame 600 , and the chuck is connected to the output shaft of the power assembly 500 .

[0062] Since the carrying device includes a chuck, when different parts need to be carried, the collet 100 on the chuck can be quickly replaced to meet the clamping requirements of different parts. Throughout the process, while ensuring the carrying effect of different parts, the working efficiency of the carrying device is improved, and the application range of the chuck and the carrying device is expanded.
