Description

Technical Field

[0001] This application relates to the technical field of jigs, and more specifically, to a positioning jig and a clamping device. Background Art

[0002] When processing or assembling workpieces, generally, multiple workpieces can be clamped onto the corresponding processing equipment at one time. After the processing or assembly of the workpieces is completed, the processed workpieces need to be removed one by one, and then a number of the next batch of workpieces to be processed are re-clamped in sequence before the equipment can be started again. The time taken for clamping or removing the workpieces is relatively long, resulting in low efficiency of processing or assembling the workpieces. Summary of the Utility Model

[0003] In view of this, this application provides a positioning jig for pre-clamping multiple workpieces to be processed. By installing the positioning jig with multiple workpieces onto the equipment for processing the workpieces, the clamping operation of multiple workpieces can be quickly completed, thereby achieving the effect of improving the processing efficiency of the workpieces.

[0004] An embodiment of this application provides a positioning jig, which includes a positioning base, a plurality of positioning components, and an elastic member. Each positioning component includes an abutting member and a clamping member. The abutting member is disposed on the positioning base, and the clamping member is slidably disposed on the positioning base. The elastic member is disposed on the positioning base. The clamping member is configured to abut against opposite sides of the workpiece together with an abutting member under the drive of the elastic member.

[0005] In the above embodiment, when clamping the workpiece, the clamping member is moved in a direction away from the corresponding abutting member, and the elastic member undergoes elastic deformation. The elastic member has an elastic force that causes the clamping member to move in the direction towards the abutting member. Then, the workpiece is placed between the clamping member and the corresponding abutting member, and the clamping member is released. The clamping member moves in the direction towards the corresponding abutting member under the action of the elastic force and pushes against the workpiece, so that the clamping member and the corresponding abutting member respectively abut against opposite sides of the workpiece to clamp the workpiece, thereby fixing the workpiece. When processing the workpiece, the positioning jig with multiple workpieces pre-clamped is installed onto the corresponding equipment, that is, the operation of clamping multiple workpieces onto the equipment is completed; during the process of the equipment processing the workpiece, the next batch of workpieces to be processed can be clamped onto another positioning jig, or multiple positioning jigs with workpieces already clamped are prepared in advance. After the workpiece on the equipment is processed, the corresponding positioning jig is removed, and another positioning jig with multiple workpieces already clamped is installed. In this way, the time taken to clamp the workpiece onto the equipment or remove it from the equipment can be shortened, which is beneficial to shortening the equipment downtime, and thus the efficiency of the equipment in processing the workpiece can be improved.

[0006] In some embodiments of the present application, a first receiving groove is provided on one side of the clamping member facing the corresponding abutting member, and a second receiving groove is provided on one side of the abutting member facing the corresponding clamping member. The first receiving groove and the second receiving groove are configured to respectively receive one side of the workpiece.

[0007] In the above embodiment, the opposite sides of the workpiece are respectively accommodated in the first accommodating groove and the second accommodating groove. The first accommodating groove and the second accommodating groove can constrain the position of the workpiece relative to the positioning seat, which is beneficial to improve the stability of keeping the workpiece fixed, and at the same time is beneficial to improve the position accuracy of the workpiece relative to the positioning seat, which is beneficial to improve the subsequent processing accuracy or assembly processing accuracy of the workpiece.

[0008] In some embodiments of the present application, the positioning seat is provided with a plurality of sliding grooves, each clamping member is slidably disposed in a sliding groove, and the sliding groove is configured to guide the sliding of the clamping member. The positioning fixture further includes a cover plate, which is detachably connected to the positioning seat, and the cover plate abuts against a side of the clamping member away from the sliding groove to prevent the clamping member from leaving the sliding groove.

[0009] In the above embodiment, when installing the clamp, the clamp can be placed in the sliding groove first, and then the cover plate is connected to the positioning seat, so that the cover plate abuts against the side of the clamp facing away from the sliding groove, so that the cover plate stops the clamp, reducing the possibility of the clamp escaping from the sliding groove. The sliding groove is used to guide the clamp, which is conducive to improving the sliding stability of the clamp. The cover plate and the positioning seat are detachably connected, which is convenient for removing or installing the clamp, so that it is convenient to replace the corresponding clamp according to the model or size of the workpiece, which is conducive to improving the applicability of this positioning fixture to different types of workpieces.

[0010] In some embodiments of the present application, the positioning seat is provided with a limiting portion, the clamping member is provided with an abutting portion, and the abutting portion is engaged with the limiting portion. The limiting portion is configured to restrict the movement range of the abutting portion along the sliding direction of the clamping member.

[0011] In the above embodiment, the limiting portion can constrain the movement range of the abutment portion along the sliding direction of the clamping member, thereby constraining the movement range of the clamping member to reduce the possibility of the clamping member disengaging from the sliding groove along its own sliding direction. At the same time, the minimum distance between the clamping member and the abutment can be limited to keep the clamping member and the abutment separated, so as to facilitate the movement of the clamping member or shorten the distance that the clamping member moves away from the abutment when clamping the workpiece, so as to facilitate clamping the workpiece and improve the efficiency of workpiece clamping.

[0012] In some embodiments of the present application, the elastic member is disposed between the limiting portion and the abutting portion, one end of the elastic member abuts against the limiting portion, and the other end abuts against the abutting portion. The elastic member is in a compressed and deformed state.

[0013] In the above embodiments, when installing the elastic member, one end of the elastic member is abutted against the limiting portion, and then the elastic member is compressed and the other end of the elastic member is abutted against the abutting portion. The elastic member is in a compressed and deformed state, so that both ends of the elastic member are respectively kept in abutment with the abutting portion and the limiting portion, which can improve the installation stability of the elastic member. When the elastic member needs to be replaced after long-term use, the elastic member can be compressed to separate the elastic member from the abutting portion or the limiting portion, so as to remove the elastic member, and the operation is convenient.

[0014] In some embodiments of the present application, the positioning fixture further includes a connecting seat, and the connecting seat is detachably connected to the positioning seat. The connecting seat is configured to be connected to a device for processing workpieces.

[0015] In the above embodiments, the positioning seat is connected to a device for processing or assembling workpieces through the connecting seat. By replacing the connecting seat, different devices can be applied.

[0016] An embodiment of the present application also discloses a clamping device, including a fixed seat, a connecting member and the above-mentioned positioning fixture. The connecting member is arranged on the fixed seat and is configured to be detachably connected to a plurality of clamping members, and the connecting member can move relative to the positioning seat along the sliding direction of the clamping members.

[0017] In the above embodiments, after the connecting member is connected to a plurality of clamping members, moving the connecting member or the positioning seat along the sliding direction of the clamping members can make the plurality of clamping members synchronously move away from the corresponding abutting members respectively, so as to achieve the effect of opening the positioning fixture for installing workpieces. After the workpiece is placed between the clamping member and the corresponding abutting member, moving the connecting member or the positioning seat in the reverse direction again or separating the clamping member from the connecting member can make the clamping member move towards the corresponding abutting member to clamp the workpiece.

[0018] In some embodiments of the present application, the connecting member includes an installation portion and a plurality of connecting portions. The connecting portions are connected to the installation portion, and the installation portion is arranged on the fixed seat. The sliding direction of the clamping member is the first direction, and the installation portion and the positioning component are configured to be arranged in sequence along the third direction, and the third direction intersects with the first direction. The clamping member is provided with an insertion hole, and the connecting portion is configured to be inserted into the corresponding insertion hole along the third direction for connecting the connecting portion with the corresponding clamping member.

[0019] In the above embodiments, when using this clamping device, first move the positioning seat towards the fixed seat along the third direction and insert the connecting portion into the insertion hole so that the connecting portion is connected to the corresponding clamping member. When the connecting portion moves relative to the positioning seat along the first direction, the connecting portion abuts against the inner wall on one side of the insertion hole along the first direction, so that the clamping member moves relative to the abutting member. After the workpiece clamping is completed, move the positioning seat away from the fixed seat along the third direction, and the connecting portion and the insertion hole can be automatically separated, separating the connecting portion from the clamping member, so as to clamp and fix the workpiece by the elastic member between the clamping member and the abutting member.

[0020] In some embodiments of the present application, the fixing base is provided with a positioning portion, the positioning seat is provided with a mating portion, the mating portion is configured to engage with the positioning portion and slidably cooperate with the positioning portion along a third direction, and the mounting portion is movable relative to the fixing base along a first direction.

[0021] In the above embodiments, the mating portion engages and slidably cooperates with the positioning portion, which can restrict the position of the positioning seat relative to the fixing base, facilitating the alignment of the insertion hole with the corresponding connecting portion, and thus facilitating the insertion of the connecting portion into the corresponding insertion hole. After the connecting portion is inserted into the insertion hole, moving the mounting portion along the first direction, the mounting portion can drive the connecting portion to move synchronously, so that the clamping member moves relative to the abutting member.

[0022] In some embodiments of the present application, the positioning jig further includes a driving member, the driving member is disposed on the fixing base, and the driving member is configured to drive the connecting member or the positioning seat to move along the sliding direction of the clamping member.

[0066] The following specific embodiments will further illustrate the present application in conjunction with the above-mentioned drawings. Specific Embodiments

[0067] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0068] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments, and are not intended to limit this application.

[0069] The terms "first" and "second" used herein are only for descriptive purposes, and cannot be construed as indicating or implying relative importance.

[0070] The embodiments of the present application provide a positioning jig, which includes a positioning base, a plurality of positioning components and an elastic member. The positioning base is configured to be connected to a device for processing workpieces. Each positioning component includes an abutting member and a clamping member. The abutting member is disposed on the positioning base, the clamping member is slidably disposed on the positioning base, and the clamping member and an abutting member are configured to respectively abut against opposite sides of the workpiece. The elastic member is disposed on the positioning base and is configured to provide an elastic force to the clamping member to cause the clamping member to slide toward the corresponding abutting member.

[0071] When clamping a workpiece, the clamping member is moved away from the corresponding abutting member, and the elastic member undergoes elastic deformation. The elastic member has an elastic force on the clamping member to cause the clamping member to move toward the abutting member. Then, the workpiece is placed between the clamping member and the corresponding abutting member and the clamping member is released. The clamping member moves toward the corresponding abutting member under the action of the elastic force and pushes against the workpiece, so that the clamping member and the corresponding abutting member respectively abut against opposite sides of the workpiece to clamp the workpiece, thereby fixing the workpiece. When processing the workpiece, the positioning jig pre-clamping a plurality of workpieces is installed on the corresponding device, that is, the operation of clamping a plurality of workpieces on the device is completed; during the process of the device processing the workpiece, the next batch of workpieces to be processed can be clamped on another positioning jig, or a plurality of positioning jigs pre-clamping workpieces can be prepared in advance. After the workpiece on the device is processed, the corresponding positioning jig is removed and another positioning jig pre-clamping a plurality of workpieces is installed. In this way, the time for clamping the workpiece on the device can be shortened, which is beneficial to improving the efficiency of clamping the workpiece on the device, shortening the downtime of the device, and thus improving the efficiency of the device processing the workpiece.

[0072] The following will describe in detail some embodiments of the present application with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0073] Referring to Figure 1 and Figure 2 , an embodiment of the present application provides a positioning fixture 100. The positioning fixture 100 includes a positioning base 1, a plurality of positioning components 2, and an elastic member 3. Each positioning component 2 includes an abutting member 21 and a clamping member 22. The abutting member 21 is disposed on the positioning base 1, and the clamping member 22 is slidably disposed on the positioning base 1. The elastic member 3 is disposed on the positioning base 1. The clamping member 22 is configured to abut against opposite sides of a workpiece (not shown in the figure) together with an abutting member 21 under the urging of the elastic member 3. The sliding direction of the clamping member 22 is the first direction X.

[0074] When clamping the workpiece, the clamping member 22 is moved away from the corresponding abutting member 21, the elastic member 3 undergoes elastic deformation, and the elastic member 3 exerts an elastic force on the clamping member 22 towards the abutting member 21. Then, the workpiece is placed between the clamping member 22 and the corresponding abutting member 21 and the clamping member 22 is released. The clamping member 22 moves towards the corresponding abutting member 21 under the action of the elastic force and pushes against the workpiece, so that the clamping member 22 and the corresponding abutting member 21 respectively abut against opposite sides of the workpiece to clamp the workpiece, thereby fixing the workpiece to the positioning fixture 100. By installing the positioning base 1 of the positioning fixture 100 pre-clamped with a plurality of workpieces to the corresponding equipment, the operation of clamping a plurality of workpieces to the equipment is completed, which can improve the efficiency of clamping the workpieces to the equipment, shorten the equipment downtime, and thus improve the efficiency of the equipment for processing workpieces.

[0075] Referring to Figure 3 , in some embodiments, the positioning base 1 is in a flat plate shape, and the surfaces on both sides of the positioning base 1 along its thickness direction are respectively a first surface 11 and a second surface 12. A plurality of relief grooves 111 are formed in the first surface 11 of the positioning base 1. The plurality of relief grooves 111 are arranged at intervals along the first direction X, and each relief groove 111 extends along the second direction Y. The second direction Y is perpendicular to the first direction X. In other embodiments, the positioning base 1 may be in a frame shape connected by a plurality of rod-shaped structures or in other shapes.

[0076] Referring to Figure 2 and Figure 3 , first protrusion portions 13 and second protrusion portions 14 are respectively formed on both sides of each relief groove 111 along the first direction X ( Figure 3The dotted line in the figure is used to separate the first protrusion 13 and the second protrusion 14 to show the positions of the first protrusion 13 and the second protrusion 14). In some embodiments, the abutment member 21 is the first protrusion 13, and the clamping member 22 is disposed on the corresponding second protrusion 14. In some embodiments, along the first direction X, the first protrusion 13 and the second protrusion 14 are arranged alternately in sequence. In other embodiments, the two first protrusions 13 or the two second protrusions 14 formed by two adjacent clearance grooves 111 can be arranged adjacently.

[0077] Reference Figure 3 and Figure 4 In some embodiments, the positioning seat 1 is provided with a plurality of sliding grooves 15, and each clamping member 22 is slidably disposed in a sliding groove 15. Each second protrusion 14 is provided with a sliding groove 15, and a plurality of sliding grooves 15 are sequentially spaced along the second direction Y, and each sliding groove 15 is communicated with a corresponding giving way groove 111. The clamping member 22 is located in the sliding groove 15, and the clamping member 22 can slide along the sliding groove 15 relative to the second protrusion 14, so that the clamping member 22 is connected to the corresponding second protrusion 14. When the clamping member 22 slides toward the corresponding abutment member 21, one end of the clamping member 22 close to the corresponding abutment member 21 can extend to the giving way groove 111, so that the clamping member 22 can abut the workpiece against the corresponding abutment member 21, thereby fixing the workpiece. In some embodiments, the clamping member 22 is plate-shaped, and the side walls of the clamping member 22 on both sides along the second direction Y are in contact with the inner wall of the sliding groove 15 , which is beneficial to improve the sliding stability of the clamping member 22 .

[0078] In other embodiments, the abutment member 21 can be detachably connected to the positioning seat 1 by means of screws, clamping, or magnetic attraction. In other embodiments, the abutment member 21 can be fixedly connected to the positioning seat 1 by means of welding or bonding.

[0079] In addition to the above-mentioned connection mode of the clamping member 22 and the sliding groove 15 in a sliding cooperation, in other embodiments, the clamping member 22 can also be slidably connected to the positioning seat 1 through a slide rail or other guiding structures.

[0080] Reference Figure 2 and Figure 4 In some embodiments, the positioning seat 1 is provided with a limiting portion 16, and the clamping member 22 is provided with an abutting portion 221, which is engaged with the limiting portion 16. The limiting portion 16 is configured to constrain the movement range of the abutting portion 221 along the sliding direction of the clamping member 22, thereby constraining the movement range of the clamping member 22 to reduce the possibility of the clamping member 22 escaping from the sliding groove 15. At the same time, the minimum distance between the clamping member 22 and the abutting member 21 can be limited, so that the clamping member 22 and the abutting member 21 remain in a separated state, so as to facilitate the movement of the clamping member 22 or shorten the distance that the clamping member 22 moves away from the abutting member 21 when clamping the workpiece.

[0081] In some embodiments, limiting grooves 141 are formed on both sides of each sliding groove 15 along the second direction Y, and the limiting grooves 141 communicate with the corresponding sliding grooves 15. On both sides of the clamping member 22 along the second direction Y, abutting blocks 222 are integrally formed. Each abutting block 222 is located in the corresponding limiting groove 141, and the dimension of each abutting block 222 along the first direction X is smaller than the dimension of the limiting groove 141 along the first direction X. The limiting portion 16 is the limiting groove 141, and the abutting portion 221 is the abutting block 222. When the clamping member 22 moves along the first direction X, the abutting block 222 moves relative to the inner wall of the limiting groove 141. When the abutting block 222 abuts against the inner end wall of one end of the limiting groove 141 along the first direction X, the inner end wall of the limiting groove 141 can limit the continuous movement of the abutting block 222, thereby limiting the movement range of the clamping member 22.

[0082] In some other embodiments, only one limiting groove 141 is formed on one side of the sliding groove 15. Correspondingly, only one abutting block 222 is provided on the clamping member 22.

[0083] In some other embodiments, the inner wall of the sliding groove 15 is provided with the abutting block 222, the clamping member 22 is provided with the limiting groove 141, the abutting block 222 is inserted into the limiting groove 141, the limiting portion 16 is the abutting block 222, and the abutting portion 221 is the limiting groove 141.

[0084] In some other embodiments, the limiting portion 16 includes two limiting protrusions arranged at intervals in sequence along the first direction X. Both limiting protrusions are connected to the positioning seat 1, and the abutting portion 221 is connected to the clamping member 22 and protrudes between the two limiting protrusions. When the clamping member 22 slides along the first direction X, the abutting portion 221 can abut against one of the limiting protrusions, and the limiting protrusion can limit the continuous movement of the abutting portion 221, thereby limiting the movement range of the clamping member 22.

[0085] Referring to Figure 2 and Figure 4 , in some embodiments, the elastic member 3 is disposed between the limiting portion 16 and the abutting portion 221. One end of the elastic member 3 abuts against the limiting portion 16, and the other end abuts against the abutting portion 221. The elastic member 3 is in a state of compressive deformation.

[0086] In some embodiments, the elastic member 3 is a spring, and the elastic member 3 is disposed in the limiting groove 141, and the elastic member 3 is located on the side of the abutting portion 221 along the first direction X and away from the corresponding abutting block 222. One end of the elastic member 3 abuts against the abutting block 222, and the other end abuts against the inner end wall of the limiting groove 141. The elastic member 3 is in a compressed and deformed state, so that the abutting block 222 and the inner end wall of one end of the limiting groove 141 close to the corresponding abutting member 21 are kept in abutment, and the elastic member 3 applies an elastic force toward the corresponding abutting member 21 to the clamping member 22 through the abutting block 222.

[0087] In other embodiments, the elastic member 3 may be disposed outside the limiting groove 141, one end of the elastic member 3 is fixedly connected to the clamping member 22, and the other end is fixedly connected to the positioning seat 1, and the elastic member 3 is in a stretched and deformed state, so that the abutment block 222 and the inner end wall of the limiting groove 141 close to the corresponding abutment member 21 are kept in abutment. In other embodiments, the elastic member 3 may also be an elastic rope or a rubber belt or other elastic structural member.

[0088] Reference Figure 2 In some embodiments, the positioning fixture 100 further includes a cover plate 4, which is detachably connected to the positioning seat 1, and the cover plate 4 abuts against the side of the clamping member 22 away from the sliding groove 15 to stop the clamping member 22 from leaving the sliding groove 15. It can be understood that the number of the cover plates 4 is the same as the number of the second protrusions 14, and the cover plate 4 is covered on the second protrusions 14 and connected to the second protrusions 14 by screws. In other embodiments, the cover plate 4 and the positioning seat 1 can be connected by snap connection, magnetic attraction or other connection structures.

[0089] When installing the clamping member 22, the clamping member 22 can be placed in the sliding groove 15 first, and then the cover plate 4 is connected to the positioning seat 1, so that the cover plate 4 abuts against the side of the clamping member 22 away from the sliding groove 15, so that the cover plate 4 stops the clamping member 22, reducing the possibility of the clamping member 22 escaping from the sliding groove 15. The cover plate 4 is detachably connected to the positioning seat 1, which is convenient for removing or installing the clamping member 22, so that it is convenient to replace the corresponding clamping member 22 according to the model or size of the workpiece, which is conducive to improving the applicability of the positioning fixture 100 to different types of workpieces.

[0090] Reference Figure 2 In some embodiments, the clamping member 22 is provided with a first receiving groove 223 on one side facing the corresponding abutting member 21, and the abutting member 21 is provided with a second receiving groove 211 on one side facing the corresponding clamping member 22. The first receiving groove 223 and the second receiving groove 211 are configured to receive one side of the workpiece, respectively.

[0091] Opposite sides of the workpiece are respectively received in the first receiving groove 223 and the second receiving groove 211. The first receiving groove 223 and the second receiving groove 211 can restrict the position of the workpiece relative to the positioning seat 1, thereby facilitating improving the stability of the workpiece to remain fixed and, at the same time, facilitating improving the position accuracy of the workpiece relative to the positioning seat 1, which is conducive to improving the subsequent processing accuracy or assembly accuracy of the workpiece.

[0092] In some embodiments, the inner sidewalls of the first receiving groove 223 and the second receiving groove 211 are both shaped to conform to the sidewall of the workpiece. Exemplarily, the shape of the workpiece is disc-shaped, and both the first receiving groove 223 and the second receiving groove 211 are arc-shaped grooves.

[0099] Referring to Figure 5 and Figure 6 , an embodiment of the present application also discloses a clamping device 600. The clamping device 600 includes a fixed seat 6, a connecting member 7, and the above-mentioned positioning fixture 100. The connecting member 7 is disposed on the fixed seat 6 and is configured to be detachably connected to a plurality of clamping members 22, and the connecting member 7 can move relative to the positioning seat 1 along the sliding direction of the clamping members 22.

[0100] In some embodiments, the fixing base 6 is in the shape of a hollow shell. In other embodiments, the fixing base 6 is in the shape of a plate, a block, a frame, or other shapes.

[0101] After connecting the connecting member 7 with a plurality of clamping members 22, moving the connecting member 7 or the positioning seat 1 along the sliding direction of the clamping members 22 can cause the plurality of clamping members 22 to move synchronously and respectively away from the corresponding abutting members 21 for installing a workpiece. After the workpiece is placed between the clamping members 22 and the corresponding abutting members 21, moving the connecting member 7 or the positioning seat 1 in the reverse direction again can cause the clamping members 22 to move towards the corresponding abutting members 21 to fix the workpiece. In other embodiments, after the workpiece is placed between the clamping members 22 and the corresponding abutting members 21, without moving the connecting member 7 or the positioning seat 1 in the reverse direction, the clamping members 22 can be separated from the connecting member 7, so that the clamping members 22 can be pressed against the workpiece by the elastic force of the elastic member 3.

[0102] Referring to Figure 6 and Figure 7 , in some embodiments, the connecting member 7 includes a mounting portion 71 and a plurality of connecting portions 72. The connecting portions 72 are connected to the mounting portion 71. The mounting portion 71 is disposed on the fixing base 6. The mounting portion 71 and the positioning assembly 2 are configured to be sequentially arranged along a third direction Z, and the third direction Z intersects with the first direction X. The clamping member 22 is provided with an insertion hole 224. The connecting portion 72 is configured to be inserted into the corresponding insertion hole 224 along the third direction Z for connecting the connecting portion 72 with the corresponding clamping member 22.

[0103] In some embodiments, the mounting portion 71 is in the shape of a frame formed by connecting a plurality of rods, and the mounting portion 71 is disposed inside the fixing base 6. A plurality of through holes 61 are formed in the outer wall of the fixing base 6. The connecting portion 72 is in the shape of a rod. One end of each connecting portion 72 is connected to the mounting portion 71, and the other end of each connecting portion 72 extends from a through hole 61 to the outside of the fixing base 6 along the third direction Z.

[0104] In some embodiments, the third direction Z is perpendicular to both the first direction X and the second direction Y. It can be understood that both the connecting seat 5 and the positioning seat 1 are provided with communication holes 51 along the third direction Z. The communication holes 51 communicate with the sliding grooves 15. The side wall of the clamping member 22 facing the bottom wall of the sliding groove 15 is provided with an insertion hole 224. In some embodiments, the insertion hole 224 is a closed annular hole. When using this clamping device 600, first make the second surface 12 of the positioning seat 1 face the connecting portion 72, and then move the positioning seat 1 towards the fixing base 6 along the third direction Z, so that the connecting portion 72 is inserted into the insertion hole 224 through the communication hole 51, so that the connecting portion 72 is connected to the corresponding clamping member 22. It can be understood that there is a gap between the inner wall of the communication hole 51 and the connecting portion 72 for the connecting portion 72 to move relative to the positioning seat 1 along the first direction X.

[0105] In some embodiments, after the connecting portion 72 is inserted into the insertion hole 224, the second surface 12 can be in contact with the fixed seat 6, and the fixed seat 6 can support the positioning seat 1. In other embodiments, the third direction Z can be parallel to the second direction Y.

[0106] In other embodiments, the clamping member 22 is provided with a protrusion extending along the third direction Z, and the connecting member 7 is provided with a concave hole for the protrusion to be inserted. By inserting the protrusion of the clamping member 22 into the concave hole of the connecting member 7 along the third direction Z, the connecting member 7 and the clamping member 22 can be detachably connected. In other embodiments, the clamping member 22 and the connecting member 7 can also be connected by magnetic attraction or negative pressure adsorption or other detachable connection means.

[0107] Referring to Figure 6 and Figure 7 , in some embodiments, the clamping device 600 further includes a driving member 8, the driving member 8 is disposed on the fixed seat 6, and the driving member 8 is configured to drive the connecting member 7 or the positioning seat 1 to move along the first direction X. In some embodiments, the driving member 8 is a cylinder, the cylinder body of the driving member 8 is connected to the inner wall of the fixed seat 6, and the piston rod of the driving member 8 is fixedly connected to the mounting portion 71. It can be understood that there is a gap between the inner wall of the through hole 61 and the connecting portion 72 for the connecting portion 72 to move relative to the fixed seat 6 along the first direction X. When the driving member 8 drives the mounting portion 71 to move along the first direction X, the connecting portion 72 moves relative to the positioning seat 1, and the connecting portion 72 abuts against the inner wall of one side of the insertion hole 224 along the first direction X, so that the connecting portion 72 drives the clamping member 22 to move relative to the abutting member 21 for placing or clamping the workpiece. After the workpiece clamping is completed, the positioning seat 1 is moved away from the fixed seat 6 along the third direction Z, and the connecting portion 72 is automatically separated from the insertion hole 224, and the operation is simple and convenient.

[0108] In other embodiments, the mounting portion 71 can be fixed to the fixed seat 6, and the driving member 8 is disposed outside the fixed seat 6. After the connecting portion 72 is inserted into the insertion hole 224, the driving member 8 can push the positioning seat 1 along the first direction X for the positioning seat 1 to move relative to the connecting portion 72, so that the clamping member 22 can move relative to the corresponding abutting member 21 for placing the workpiece. In other embodiments, the driving member 8 can be omitted, and the mounting portion 71 or the positioning seat 1 can be manually driven to move to realize the movement of the clamping member 22 relative to the abutting member 21.

[0109] Referring to Figure 8, in some embodiments, the fixing base 6 is provided with a positioning portion 62, and the positioning seat 1 is provided with a mating portion (not shown in the figure). The mating portion is configured to engage with the positioning portion 62 and slidably cooperate with the positioning portion 62 along the third direction Z. In some embodiments, the positioning portion 62 is a positioning pin, the positioning portion 62 is fixedly connected to the fixing base 6, and the length direction of the positioning portion 62 extends along the third direction Z; the mating portion is a positioning hole (not shown in the figure), and the mating portion is provided on the connecting seat 5. In other embodiments, the mating portion may be provided on the positioning seat 1.

[0110] When the positioning seat 1 is moved closer to the fixing base 6 along the third direction Z, the positioning portion 62 can be inserted into the mating portion and slidably connected to the mating portion to restrict the position of the positioning seat 1 relative to the fixing base 6, thereby facilitating the insertion of the connecting portion 72 into the insertion hole 224, and at the same time improving the stability of the positioning seat 1 to remain fixed when moving on the mounting portion 71.

[0111] In some embodiments, the positioning portion 62 is a cylindrical pin, and the number of the positioning portions 62 is two. Correspondingly, there are two mating portions, and each positioning portion 62 is inserted into a corresponding mating portion. In other embodiments, the number of the positioning portions 62 and the mating portions may also be three or more. In other embodiments, the number of the positioning portions 62 and the mating portions may also be one each, and the cross-section of the positioning portion 62 is square or other shapes other than circular, as long as the positioning seat 1 can only slide relative to the fixing base 6 along the third direction Z after the mating portion is connected to the positioning portion 62.

[0112] In other embodiments, the positioning portion 62 may be a positioning hole opened in the fixing base 6. Correspondingly, the mating portion is a positioning pin connected to the connecting seat 5 or the positioning seat 1.

[0113] In some embodiments, the usage mode of the clamping device 600 is as follows:

[0114] First, align the mating part with the positioning part 62 along the third direction Z. Then, move the positioning seat 1 towards the fixed seat 6 along the third direction Z, so that the mating part engages with the positioning part 62, insert the connecting part 72 into the insertion hole 224, and make the positioning seat 1 abut against the fixed seat 6. Then, start the driving member 8. The driving member 8 drives the mounting part 71 to move along the first direction X. The mounting part 71 drives the clamping member 22 to move away from the corresponding abutting member 21 through the connecting part 72, so that each clamping member 22 is separated from the corresponding abutting member 21 by a certain interval. Then, after placing the workpiece between the clamping member 22 and the corresponding abutting member 21, the driving member 8 drives the mounting part 71 to move in the reverse direction, so that the clamping member 22 moves towards the corresponding abutting member 21 by a certain distance, so that the clamping member 22 and the corresponding abutting member 21 clamp the corresponding workpiece. Finally, move the positioning seat 1 away from the fixed seat 6 along the third direction Z, so that the connecting part 72 can be separated from the insertion hole 224 and the clamping member 22 can be pressed against the workpiece by the elastic force of the elastic member 3, thereby completing the operation of clamping multiple workpieces to the positioning seat 1.

[0115] In addition, those of ordinary skill in the art in this technical field should recognize that the above embodiments are only used to illustrate the present application, rather than to limit the present application.
