[0068] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0069] See also Figure 1 The embodiment of the present application provides a positioning and clamping mechanism 100, including a positioning component 10, a clamping component 20 and a pressing component 30, for realizing accurate clamping of multiple workpieces 200. The workpieces 200 may be carbon fiber rod raw materials, metal rods, and the like.

[0070] The positioning assembly 10 is provided with a plurality of positioning grooves 11 arranged at intervals, and the positioning grooves 11 are used to position the workpieces 200. The clamping assembly 20 includes a plurality of clamping members 21, and the plurality of clamping members 21 are arranged one by one corresponding to the plurality of positioning grooves 11, and the clamping members 21 are received in the corresponding positioning grooves 11. The pressing assembly 30 includes a supporting member 31, a pressing driving member 32 and a pressing member 33, the supporting member 31 is arranged on one side of the positioning assembly 10, the pressing driving member 32 is arranged on the supporting member 31 and connected to the pressing member 33, the pressing driving member 32 is used to drive the pressing member 33 to press the plurality of workpieces 200 and the plurality of clamping members 21 to the bottom of the positioning groove 11 at the same time, so that the plurality of workpieces 200 and the corresponding clamping members 21 are coaxially arranged in the positioning groove 11, and the clamping member 21 is used to be coaxially connected to the corresponding workpiece 200 under the action of external force.

[0071] In the above-mentioned positioning and clamping mechanism 100, multiple workpieces 200 are positioned simultaneously through multiple positioning grooves 11, so that multiple clamping members 21 can be accurately abutted against the corresponding workpieces 200 respectively, and the pressing member 33 is driven by the pressing driving member 32 to press the multiple workpieces 200 and the corresponding clamping members 21 to the bottom of the positioning groove 11 at the same time, so that the multiple workpieces 200 and the corresponding clamping members 21 are coaxially arranged, and eccentric errors between the workpieces 200 and the clamping members 21 are avoided, which is beneficial to the coaxial connection of the clamping member 21 with the corresponding workpiece 200, and the accurate coaxial connection of the clamping member 21 with the workpiece 200 is achieved, thereby improving the clamping accuracy.

[0072] See also Figure 2 In some embodiments, the pressing member 33 includes a first flexible body 331 and a second flexible body 332, which are arranged at intervals along the extending direction of the positioning groove 11 and are both connected to the pressing driving member 32, the first flexible body 331 is used to flexibly press the workpiece 200 and the clamping member 21 at the same time, and the second flexible body 332 is used to flexibly press the end of the clamping member 21 adjacent to the workpiece 200. Exemplarily, the material of the first flexible body 331 can be eutectic.

[0073] In this way, by setting the specific structure of the above-mentioned pressing member 33, when the first flexible body 331 presses the workpiece 200 and the clamping member 21 into the positioning groove 11, the second flexible body 332 synchronously presses the end of the clamping member 21 adjacent to the workpiece 200 into the positioning groove 11, so as to simultaneously press different positions on the same side of the clamping member 21, thereby preventing the clamping member 21 from swinging when clamping and connecting the workpiece 200, and improving the clamping accuracy. In addition, the first flexible body 331 flexibly presses the workpiece 200 and the clamping member 21, and the second flexible body 332 flexibly presses the clamping member 21, so that the pressing member 33 can flexibly press the workpiece 200 and the clamping member 21, thereby preventing the pressing member 33 from applying too much pressure to the workpiece 200 and the clamping member 21 and damaging the workpiece 200 and the clamping member 21, which is beneficial to ensuring the quality of the workpiece 200 and the service life of the clamping member 21.

[0074] Please continue reading Figure 2In some embodiments, the second flexible body 332 includes a connecting portion 3321, a limiting portion 3322, a pressing portion 3323 and an elastic portion 3324. The connecting portion 3321 is connected to the pressing driving member 32, one end of the limiting portion 3322 is movably arranged in the connecting portion 3321, and the other end of the limiting portion 3322 is used to abut against the side of the connecting portion 3321 away from the positioning assembly 10. The pressing portion 3323 is connected to the end of the limiting portion 3322 away from the connecting portion 3321, and is used to move close to the positioning groove 11 under the drive of the limiting portion 3322 to press the clamping member 21. The elastic force direction of the elastic portion 3324 is parallel to the direction of the connecting portion 3321 pointing to the pressing portion 3323, and the two ends of the elastic portion 3324 are respectively abutted against the pressing portion 3323 and the connecting portion 3321. Exemplarily, the limiting portion 3322 can be a bolt, and the elastic portion 3324 can be a spring. It can be understood that there can be multiple elastic portions 3324 , and the multiple elastic portions 3324 are arranged at intervals between the pressing portion 3323 and the connecting portion 3321 .

[0075] In this way, when the second flexible body 332 presses against the clamping part 21, the pressing driving member 32 drives the connecting part 3321 to drive the pressing part 3323 to move close to the clamping part 21 through the limiting part 3322, and at the same time, the connecting part 3321 compresses the elastic part 3324 to the pressing part 3323, so that the pressing part 3323 can flexibly press the clamping part 21 to the positioning groove 11. When the second flexible body 332 completes the pressing operation, the compressed elastic part 3324 provides elastic force and the pressing driving member 32 provides driving force to jointly drive the connecting part 3321 to move away from the clamping part 21, so that the connecting part 3321 is reset to the initial position, which is convenient for the second flexible body 332 to repeat the pressing operation. In addition, by providing the above-mentioned limiting portion 3322, the limiting portion 3322 can limit the movement direction of the connecting portion 3321 when the connecting portion 3321 moves closer to or away from the clamping member 21, and when the connecting portion 3321 is reset to the initial position, one end of the limiting portion 3322 away from the pressing portion 3323 abuts against the side of the connecting portion 3321 away from the pressing portion 3323, thereby limiting the reset position of the connecting portion 3321.

[0076] It can be understood that in this embodiment, the material of the clamping part 21 is metal, and the second flexible body 332 will produce friction, damage, etc. with the clamping part 21 during the process of the clamping part 21 clamping and connecting the workpiece 200. Therefore, the second flexible body 332 is set to a split structure to facilitate the replacement of the pressing part 3323 after long-term operation.

[0077] In some embodiments, the lengths of the first flexible body 331 and the second flexible body 332 in the direction perpendicular to the extending direction of the positioning groove 11 are greater than or equal to the length of the positioning assembly 10 in the direction perpendicular to the extending direction of the positioning groove 11 .

[0078] In this way, by setting the length dimension relationship between the first flexible body 331, the second flexible body 332 and the positioning assembly 10, it can be ensured that the first flexible body 331 and the second flexible body 332 can simultaneously press multiple workpieces 200 and multiple clamping members 21 into the corresponding positioning grooves 11 during the clamping process, which is beneficial to reduce clamping errors and improve clamping stability.

[0079] See also Figure 3 In some embodiments, the positioning assembly 10 includes a positioning member 12 and a limiting member 13. A plurality of positioning grooves 11 are provided in the positioning member 12. The limiting member 13 includes a carrier 131 and a limiting member 132. The carrier 131 is connected to the positioning member 12. The carrier 131 is used to carry the workpiece 200. The limiting member 132 is provided at one end of the carrier 131 away from the positioning member 12. The limiting member 132 is used to abut against opposite ends of the workpiece 200 with the clamping member 21 to limit the workpiece 200.

[0080] In this way, by setting the specific structure of the above-mentioned positioning assembly 10, when the workpiece 200 is placed in the positioning groove 11, the clamping member 21 pushes the workpiece 200 to move in the direction close to the limiting body 132, so that the clamping member 21 and the limiting body 132 can respectively abut against the opposite ends of the workpiece 200 to limit the workpiece 200, thereby preventing the workpiece 200 from shaking during the assembly process of the clamping member 21 and the workpiece 200 and affecting the clamping accuracy, thereby ensuring the clamping accuracy of the workpiece 200 and the clamping member 21.

[0081] Please continue reading Figure 3 In some embodiments, a plurality of limiting grooves 1321 adapted to the workpiece 200 are provided on one side of the limiting body 132 facing the positioning member 12. The plurality of limiting grooves 1321 are arranged in one-to-one correspondence with the plurality of positioning grooves 11. The limiting grooves 1321 are used to accommodate one end of the workpiece 200 away from the clamping member 21 to limit the workpiece 200.

[0082] In this way, by setting the above-mentioned limit groove 1321, the limit groove 1321 can accommodate one end of the workpiece 200 away from the clamp 21, so as to limit the end of the workpiece 200, avoid the workpiece 200 from swinging in the positioning groove 11 during the subsequent assembly process, which is conducive to the coaxial connection of the clamp 21 to the workpiece 200.

[0083] In some embodiments, the positioning groove 11 and the clamping member 21 are clearance-fitted in a direction perpendicular to the extending direction of the positioning groove 11 .

[0084] In this way, by setting a clearance fit between the positioning groove 11 and the clamping part 21, the clamping part 21 can be allowed to rotate in the positioning groove 11, so that the clamping part 21 can be quickly coaxially connected to the workpiece 200. At the same time, it helps to reduce the friction generated between the clamping part 21 and the positioning groove 11 during the clamping process, so that the clamping part 21 can rotate more smoothly, thereby improving the clamping efficiency, reducing the wear of the clamping part 21, and extending the service life of the clamping part 21.

[0085] See also Figure 2 In some embodiments, the support member 31 includes a first support body 311 and a second support body 312. The first support body 311 is disposed on one side of the positioning assembly 10, the second support body 312 is mounted above the positioning assembly 10 and connected to the first support body 311, and the pressing driving member 32 is disposed on the second support body 312.

[0086] In this way, by setting the specific structure of the above-mentioned support member 31, the first support body 311 and the second support body 312 can stably support the pressing driving member 32 and the pressing member 33 connected to the pressing driving member 32, which is beneficial to ensure the stable operation of the pressing assembly 30, and at the same time makes the layout of the pressing assembly 30 reasonable and the mechanical structure relatively simple.

[0087] See also Figure 4 In some embodiments, the clamping member 21 includes a clamping body 211 and a clamping body 212. The clamping body 211 is received in the corresponding positioning groove 11, and one end of the clamping body 211 has a clamping portion 2111, and the clamping portion 2111 is used to detachably connect the corresponding workpiece 200. The clamping body 212 is connected to the other end of the clamping body 211, and the clamping body 212 is used to clamp to an external locking member. It can be understood that in this embodiment, the end of the workpiece 200 adjacent to the clamping member 21 is provided with an internal thread structure, and the clamping portion 2111 is an external thread structure adapted to the internal thread structure, and the clamping portion 2111 is threadedly connected to the workpiece 200. In other embodiments, the workpiece 200 and the clamping portion 2111 can also be connected by plug-in connection, clamping connection, or any other structure that can achieve detachable connection.

[0088] In this way, by setting the specific structure of the above-mentioned clamping part 21, the clamping body 212 clamped to the external locking part can stably drive the clamping body 211 to rotate, so that the clamping part 2111 is stably connected to the corresponding workpiece 200, thereby ensuring that the clamping body 211 is stably coaxially connected to the workpiece 200, thereby improving the clamping stability.

[0089] See also Figure 5The embodiment of the present application further provides a processing device 300, which includes a positioning and clamping mechanism 100 and a processing device 301. The positioning and clamping mechanism 100 clamps the workpiece 200, and the processing device 301 is arranged on one side of the positioning and clamping mechanism 100 and is used to process the workpiece 200. Exemplarily, the processing device 301 can be a processing machine tool.

[0090] The working process of the above-mentioned processing equipment 300 is roughly as follows:

[0091] First, a plurality of workpieces 200 are placed in the corresponding positioning grooves 11, and then a plurality of clamps 21 are placed in the corresponding positioning grooves 11, and the clamps 21 are pushed to drive the corresponding workpieces 200 to move close to the limiting body 132, so that the clamps 21 and the limiting body 132 are respectively abutted against the opposite ends of the workpiece 200, so as to limit the workpiece 200, and prevent the workpiece 200 from shaking during the assembly process of the clamps 21 and the workpiece 200, thereby affecting the clamping accuracy;

[0092] Then, the pressing driving member 32 drives the first flexible body 331 and the second flexible body 332 to move close to the positioning member 12, so that the first flexible body 331 flexibly presses the workpiece 200 and the clamping member 21 at the same time, and the second flexible body 332 flexibly presses the clamping member 21 at one end adjacent to the workpiece 200, so that the multiple workpieces 200 and the corresponding clamping members 21 are pressed to the bottom of the positioning groove 11 at the same time, so that the multiple workpieces 200 and the corresponding clamping members 21 are coaxially arranged, and the eccentricity error between the workpiece 200 and the clamping member 21 is avoided, which is conducive to the coaxial connection between the clamping member 21 and the corresponding workpiece 200;

[0093] Next, the clamping body 212 is clamped to the external locking member and drives the clamping body 211 to rotate, so that the clamping portion 2111 is stably connected to the corresponding workpiece 200, thereby ensuring that the clamping body 211 is stably coaxially connected to the workpiece 200, thereby improving the clamping accuracy;

[0094] Finally, the processing device 301 processes the clamped workpiece 200, which is beneficial to ensuring the processing accuracy.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not intended to limit it. Although the present application has been described in detail with reference to the preferred embodiments, a person of ordinary skill in the art should understand that the technical solution of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
