[0031] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0033] In the description of the present utility model, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood to exclude the number itself, and "above", "below", "within" etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0034] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0035] It should be noted that the annular workpiece includes an inner ring and an outer ring.

[0036] refer to Figure 1 and Figure 2 According to the clamping device provided by the utility model, it includes a mounting frame 100, a clamping assembly 200 and an inner support assembly 300. The clamping assembly 200 and the inner support assembly 300 are both arranged on the mounting frame 100. The clamping assembly 200 includes a driver 210 and a plurality of clamping jaws 220. The plurality of clamping jaws 220 are located on the same horizontal plane and are distributed along the circumferential direction. Each clamping jaw 220 surrounds and forms a clamping area 201. The driver 210 is connected to each clamping jaw 220 and is used to drive each clamping jaw 220 to approach or move away from the clamping area 201; the inner support assembly 300 includes an inner support structure, and the lower end of the inner support structure extends into the clamping area 201.

[0037] When the annular workpiece needs to be clamped, the annular workpiece can be placed in the clamping area 201 so that the inner support structure extends into the inner circle of the annular workpiece to support the annular workpiece. At the same time, the driver 210 can drive each clamping jaw 220 to approach the clamping area 201 to clamp the outer circle of the annular workpiece; when the clamped annular workpiece needs to be put down, the driver 210 can drive each clamping jaw 220 away from the clamping area 201, so that the annular workpiece can be separated from the inner support structure and the clamping area 201 under the action of its own gravity.

[0038] It is understandable that when the specifications of the annular workpiece are small, due to the electrostatic effect, the annular workpiece is easy to produce adsorption effect with the internal support structure. When the clamping assembly 200 releases the annular workpiece, it is difficult for the annular workpiece to automatically separate from the internal support structure under the action of its own gravity, thereby affecting the clamping device to clamp the next annular workpiece.

[0039] Based on the above problems, in some embodiments of the present invention, reference Figure 1The clamping device further includes a material pushing assembly 400 , which is disposed on the mounting frame 100 and located at one side of the clamping area 201 .

[0040] Furthermore, when the clamping device of the present embodiment lowers the clamped annular workpiece, after the clamping assembly 200 releases the annular workpiece, the pushing assembly 400 can push the annular workpiece downward so that the annular workpiece can smoothly detach from the inner support structure and smoothly detach from the clamping area 201, thereby facilitating the clamping device of the present embodiment to clamp the next annular workpiece.

[0041] Specifically, in order to enable the pushing assembly 400 to push down the annular workpiece adhered to the inner support structure, in a specific embodiment of the present invention, the pushing assembly 400 includes a jet structure, the upper end of the jet structure is used to connect with the air supply device, and the lower end of the jet structure faces the clamping area 201, and is used to introduce a downward airflow into the clamping area 201 to blow the annular workpiece adhered to the inner support structure away from the inner support structure.

[0042] It can be understood that by setting up the jet structure, the jet structure can use the ejected airflow to blow the annular workpiece adhered to the inner support structure off the inner support structure, thereby avoiding direct contact between the pusher assembly 400 and the annular workpiece, and further reducing the probability of the pusher assembly 400 causing scratches to the annular workpiece.

[0043] Specifically, refer to Figure 1 The jet structure includes an air guide pipe 410 and an air jet head 420. The air guide pipe 410 is extended in the vertical direction. The upper end of the air guide pipe 410 is used to communicate with the air supply device. The lower end of the air guide pipe 410 is connected to the upper end of the air jet head 420. The air jet head 420 is tilted downward, and the lower end of the air jet head 420 faces the clamping area 201.

[0044] It can be understood that by tilting the nozzle head 420 downward, the nozzle structure can normally blow the annular workpiece in the clamping area 201 downward, while the air guide tube 410 can be set on the upper side of the clamping area 201 to reduce the probability of interference between the air guide tube 410 and the inner support assembly 300.

[0045] Optionally, in other embodiments of the utility model, without considering the possibility of scratching the annular workpiece caused by the pushing assembly 400, the pushing assembly 400 may also include a cylinder and a pushing piece. In this case, the cylinder is connected to the pushing piece and can drive the pushing piece to move in the vertical direction so that the pushing piece can push the annular workpiece downward to separate from the internal support structure.

[0046] In some embodiments of the present invention, the clamping assembly 200 includes two clamping jaws 220, which are horizontally arranged in parallel. The clamping jaws 220 include a connecting section 221 and a clamping section 222. The clamping section 222 is horizontally extended, and one horizontal end of the clamping section 222 is connected to the connecting section 221. The clamping area 201 is formed between the other horizontal ends of the two clamping sections 222. For example, Figure 2 As shown, the two clamping jaws 220 are arranged side by side in the left-right direction, and the clamping jaws 220 include a connecting section 221 and a clamping section 222. The connecting section 221 is extended in the vertical direction, and the clamping section 222 is extended in the front-back direction. The lower end of the connecting section 221 is connected to the rear end of the clamping section 222, and a clamping area 201 is formed between the front ends of the two clamping sections 222.

[0047] It can be understood that by extending the clamping section 222 horizontally and connecting one horizontal end of the clamping section 222 to the connecting section 221, a clamping area 201 is formed between the other horizontal ends of the two clamping sections 222, so that the clamping area 201 and the connecting section 221 can be staggered in the horizontal direction, and the inner support assembly 300 and the connecting section 221 can be staggered in the horizontal direction.

[0048] In a further embodiment of the present invention, in order to enable the clamping jaws 220 to clamp the annular workpiece more firmly, Figure 3 A side of the clamping section 222 close to the clamping area 201 is provided with an arc groove 222a adapted to the outer surface of the annular workpiece.

[0049] It should be noted that the inner ring size of some annular workpieces is relatively small.

[0050] In order to enable the inner support structure to support the annular workpiece with a small inner ring size, in some embodiments of the present invention, reference Figure 4 The inner support structure includes an inner support column 310 , and the inner support column 310 extends into the clamping area 201 .

[0051] Furthermore, when an annular workpiece with a smaller inner ring size is internally supported, the inner support column 310 can be directly inserted into the inner ring of the annular workpiece.

[0052] It can be understood that the structure of the inner support column 310 is simple and easy to implement.

[0053] It should be noted that, for annular workpieces of different specifications, the sizes of their inner rings are not exactly the same.

[0054] In order to enable the clamping device of the present application to adapt to annular workpieces of various specifications, in a further embodiment of the present utility model, reference is made to Figure 4The inner support assembly 300 further includes a mounting seat 320 , on which the inner support column 310 is detachably disposed, and the mounting seat 320 is mounted on the mounting frame 100 through the clamping assembly 200 .

[0055] It is understandable that, according to the specifications of the annular workpiece, the staff can install the inner support column 310 of the corresponding specifications on the mounting seat 320, so that the clamping device of this embodiment can adapt to annular workpieces of different specifications.

[0056] Specifically, in order to realize the detachable connection of the inner support column 310 on the mounting seat 320, in a specific embodiment of the present utility model, reference is made to Figure 5 A vertically extending mounting hole 321 is provided on the mounting seat 320, and the upper end of the inner support column 310 can be slidably inserted into the mounting hole 321. A locking hole 322 communicating with the outside is provided on the side wall of the mounting hole 321, and a locking member is threadedly inserted into the locking hole 322.

[0057] Furthermore, when installing the inner support column 310 on the mounting seat 320, the staff can pass the upper end of the inner support column 310 through the mounting hole 321, and then screw the locking piece into the locking hole 322, so that the locking piece can cooperate with the side wall of the mounting hole to fix the upper end of the inner support column 310 in the mounting hole 321; when separating the inner support column 310 from the mounting seat 320, the staff can unscrew the locking piece in the locking hole 322, at this time, the inner support column 310 can slide relative to the mounting hole 321, so that the inner support column 310 can be separated from the mounting hole 321 under the action of external force.

[0058] In order to make the inner support column 310 more firmly installed in the installation hole 321, in a further embodiment of the present utility model, Figure 6 The upper end of the inner support column 310 is provided with a clamping groove 311 adapted to the locking member.

[0059] Furthermore, after the inner support column 310 is inserted into the mounting hole 321 , the staff can screw the locking member into the locking hole 322 so that the locking member can be inserted into the snap-fit ​​groove 311 to fix the inner support column 310 .

[0060] In some embodiments of the present invention, the clamping device further includes a sensor, which is disposed on the mounting frame 100 and is used to detect whether there is an annular workpiece in the clamping area 201 .

[0061] In some embodiments of the present invention, reference Figure 1The clamping device also includes a driving assembly 500, which is connected to the mounting frame 100 and is used to drive the mounting frame 100 to move, so that the mounting frame 100 can reciprocate between the annular workpiece storage area and the annular workpiece placement area, thereby allowing the annular workpiece in the annular workpiece storage area to be transferred to the annular workpiece placement area.

[0062] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
