In addition, in order to avoid confusion with the present application, some technical features known in the art are not described in detail.

[0025] In order to thoroughly understand the embodiments of the present application, detailed structures will be proposed in the following description. Obviously, the implementation of the embodiments of the present application is not limited to the special details familiar to those skilled in the art. The preferred embodiments of the present application are described in detail as follows, however, in addition to these detailed descriptions, the present application can have other embodiments.

[0026] In one embodiment of the present application, a clamping assembly is provided, which can avoid the situation that the to-be-clamped piece 2 is dropped and damaged due to the sudden loosening of the clamping piece 1. The following will introduce a clamping assembly according to the embodiments of the present application in detail with reference to the drawings.

[0027] As Figure 1 and Figure 2As shown, the clamping assembly comprises a clamping member 1 and a supporting assembly 3. The clamping member 1 has a clamping state of clamping the to-be-clamped member 2 and an open state of releasing the to-be-clamped member 2. The supporting assembly 3 has a receiving cavity 313 arranged below the clamping member 1 and configured to support the to-be-clamped member 2 at least when the to-be-clamped member 2 is released by the clamping member 1.

[0028] The clamping member 1 can comprise a first clamping part and a second clamping part, and when the first clamping part and the second clamping part are close to each other, the clamping member 1 can be in the clamping state, and vice versa, when the first clamping part and the second clamping part are away from each other, the clamping member 1 can be in the open state.

[0029] Arc-shaped parts can be formed on the first clamping part and the second clamping part respectively, and the curvature of the arc-shaped parts can be matched with the outer contour of the to-be-clamped member 2, so that the first clamping part and the second clamping part can be clamped more firmly with the to-be-clamped member 2.

[0030] At least part of the to-be-clamped member 2 can be located in the receiving cavity 313 of the supporting assembly 3, so that the supporting assembly 3 can not only apply a supporting force to the to-be-clamped member 2 to improve the clamping effect of the clamping assembly, but also can avoid the to-be-clamped member 2 from falling when the to-be-clamped member 2 is released by the clamping member 1.

[0031] The clamping assembly of the utility model, when the clamping member 1 is in the open state, the to-be-clamped member 2 can fall into the receiving cavity 313 of the supporting assembly 3 located below the clamping member 1, so as to avoid the to-be-clamped member 2 from falling and being damaged due to the sudden release of the clamping member 1, effectively improve the reliability of the clamping assembly in use, and the safety of the operator in inspection and test.

[0032] In some embodiments, as shown in Figure 1 and Figure 2 The supporting assembly 3 comprises a sleeve 31 and a support seat 32, and the receiving cavity 313 is formed on the sleeve 31. The support seat 32 is connected with the sleeve 31, and the sleeve 31 is limited below the clamping member 1 through the support seat 32.

[0033] The bottom wall 312 of the sleeve 31 can be connected with the support seat 32, and the open side of the sleeve 31 can be located below the clamping member 1, when the to-be-clamped member 2 is placed in the receiving cavity of the sleeve 31 through the open side, the sleeve 31 can apply a supporting force to the to-be-clamped member 2 and limit the displacement of the to-be-clamped member 2.

[0034] In the above embodiment, the accommodation cavity 313 on the sleeve 31 can accurately position the to-be-clamped piece 2, so that the position of the to-be-clamped piece 2 in the sleeve 31 is more accurate, thereby facilitating clamping of the clamping piece 1. Moreover, through cooperation of the support seat 32 and the sleeve 31, more stable support force can be provided to the to-be-clamped piece 2, and displacement or tilting of the to-be-clamped piece 2 due to external force is reduced, thereby effectively improving the reliability of the bearing assembly 3.

[0035] In some embodiments, the support seat 32 and the sleeve 31 are detachably connected.

[0036] The detachable connection can specifically include plug-in connection or threaded connection, etc., which is not limited in the present application.

[0037] The sleeve 31 can have different diameters, and an operator can replace the sleeve 31 corresponding to the outer contour size of the to-be-clamped piece 2, thereby improving the adaptability between the to-be-clamped piece 2 and the bearing assembly 3.

[0038] In the above embodiment, the detachable connection makes the installation and disassembly process between the support seat 32 and the sleeve 31 more convenient and rapid. When the support seat 32 or the sleeve 31 needs to be maintained and overhauled, the bearing assembly 3 can be quickly disassembled, greatly facilitating the inspection and maintenance of the bearing assembly 3. Moreover, the disassembled support seat 32 and sleeve 31 can be reused, effectively reducing the manufacturing cost of the bearing assembly 3 and improving the convenience of use of the bearing assembly 3.

[0039] In some embodiments, as shown in Figure 3 The sleeve 31 has a side wall 311 and a bottom wall 312, the side wall 311 and the bottom wall 312 circumscribe to form the accommodation cavity 313, the bottom wall 312 of the sleeve 31 is formed with a protruding column 314 away from the accommodation cavity 313, the support seat 32 has a recessed cavity 321, and the protruding column 314 is inserted into the recessed cavity 321 to connect the support seat 32 and the sleeve 31.

[0040] In the above embodiment, through cooperation and connection between the protruding column 314 and the recessed cavity 321, stable connection between the sleeve 31 and the support seat 32 can be formed, and quick installation and disassembly between the sleeve 31 and the support seat 32 can also be achieved, which not only effectively improves the firmness of the connection between the sleeve 31 and the support seat 32, but also effectively simplifies the connection structure of the bearing assembly 3.

[0041] In some embodiments, as shown in Figure 3 The support seat 32 is provided with a clamping piece 4 beside the recessed cavity 321, the clamping piece 4 has an extended state of extending into the recessed cavity 321 and a retracted state of retracting into the support seat 32, and when the clamping piece 4 is in the extended state, one end of the clamping piece 4 abuts against the protruding column 314.

[0042] The setting direction of the clamping piece 4 can be perpendicular to the insertion direction of the convex column 314, one end of the clamping piece 4 can be located in the support seat 32, and the other end of the clamping piece 4 can extend into the recessed cavity 321.

[0043] When the convex column 314 of the sleeve 31 is inserted into the recess of the support seat 32, the clamping piece 4 located in the support seat 32 can abut against the convex column 314, thereby limiting the displacement of the sleeve 31.

[0044] In the above embodiment, the clamping piece 4 can abut against the convex column 314 of the sleeve 31, so that a stable connection is formed between the sleeve 31 and the support seat 32, and the connection strength between the above two is effectively improved.

[0045] In some embodiments, as shown in Figure 3 The clamping piece 4 includes a housing 41, an elastic piece, and a rolling piece 42, one end of the elastic piece abuts against the cavity bottom of the housing 41, the other end of the elastic piece abuts against the rolling piece 42, and at least part of the rolling piece 42 extends into the recessed cavity 321 when the clamping piece 4 is in the extended state.

[0046] The elastic piece can apply an abutting force to the rolling piece 42, and the elastic force provided by the elastic piece can be concentrated on the rolling piece 42. Specifically, when the convex column 314 is inserted into the recessed cavity 321, the convex column 314 can abut against the rolling piece 42 and push the rolling piece 42 to move towards the cavity bottom of the housing 41, at this time, the elastic piece can be in a compressed state and apply an elastic force to the rolling piece 42, so that the clamping piece 4 and the convex column 314 form a close fit, thereby improving the connection strength between the clamping piece 4 and the convex column 314.

[0047] The above-mentioned elastic piece can be a spring or elastic rubber, etc., any component that can elastically deform under force is within the scope of the present application, and the present application does not make specific limitations thereto.

[0048] In the above embodiment, the elastic piece can flexibly switch the clamping piece 4 between the extended state and the retracted state, when the clamping piece 4 is in the extended state, the elastic piece can apply a force to the rolling piece 42, so that the clamping piece 4 can be firmly connected with the convex column 314. When the clamping piece 4 is in the retracted state, the convex column 314 can be conveniently separated from the recessed cavity 321, thereby effectively improving the installation and disassembly efficiency of the sleeve 31 and the support seat 32.

[0049] In some embodiments, as shown in Figure 3 The side wall 311 of the convex column 314 forms an annular groove 315, and at least part of the rolling piece 42 extends into the annular groove 315 when the support seat 32 is connected with the sleeve 31.

[0050] In the above embodiment, the annular groove 315 can increase the contact area between the convex column 314 and the rolling member 42, thereby enhancing the strength of the connection between the clamping member 4 and the convex column 314. Moreover, the cooperation of the annular groove 315 and the rolling member 42 can also provide a more stable connection, reduce the disengagement of the sleeve 31 from the support seat 32 due to external force, and further improve the overall firmness and stability of the supporting assembly 3.

[0051] In some embodiments, as shown in Figure 3 The clamping member 4 is at least two, and the at least two clamping members 4 are arranged at intervals along the outer periphery of the convex column 314.

[0052] As shown in Figure 3 The number of clamping members 4 can be two, and the two clamping members 4 are arranged on opposite sides of the convex column 314. Of course, the number of clamping members 4 can also be three, and the three clamping members 4 can be evenly spaced in the circumferential direction of the convex column 314, and the number of clamping members 4 is not limited in the present application.

[0053] In the above embodiment, the clamping member 4 can be arranged at intervals along the outer periphery of the convex column 314, so that the convex column 314 can more evenly bear the force of the clamping member 4, effectively improving the overall stability of the supporting assembly 3. Moreover, the plurality of clamping members 4 can provide more connection points to enhance the connection strength between the convex column 314 and the clamping member 4, effectively improving the reliability of the supporting assembly 3.

[0054] In some embodiments, a guide surface is formed on the end of the convex column 314 away from the accommodation cavity 313, and the rolling member 42 slides into the annular groove 315 along the guide surface.

[0055] The guide surface can be circumferentially arranged around the end of the convex column 314 away from the accommodation cavity 313, and the guide surface can make the rolling member 42 smoothly slide into the annular groove 315.

[0056] In the above embodiment, the guide surface can guide the rolling member 42 to accurately and smoothly slide into the annular groove 315, effectively improving the convenience of the connection between the clamping member 4 and the convex column 314.

[0057] In some embodiments, the clamping assembly further comprises a sensing member arranged on the clamping member 1 and configured to sense the position information of the to-be-clamped member 2.

[0058] The clamping assembly can further comprise a control member electrically connected with the sensing member and the clamping member 1, respectively. The sensing member can sense the position information of the to-be-clamped member 2 in the sleeve 31 and generate a control instruction, and the control member can receive the control instruction and control the clamping member 1 to switch from the open state to the clamping state.

[0059] The sensing member can be a proximity sensor, an infrared sensor, or the like, and the present application does not make a specific limitation thereon, and any device capable of sensing the position information of the to-be-transported member can be used.

[0060] In the above embodiment, the sensing member can sense the accurate information of the position of the to-be-clamped member 2, and realize the automatic clamping of the clamping member 1, effectively reducing the manual intervention of the clamping assembly and improving the automation level of the clamping assembly.
