Description

Technical Field

[0001] The present application relates to the technical field of transferring workpieces, and in particular, to a clamping mechanism and a workpiece transfer device. Background Art

[0002] When assembling products or processing workpieces, sometimes it is necessary to clamp the workpiece with a jaw, and then move the jaw to a specified position and release the workpiece, so as to transfer the workpiece to a specified assembly station or processing station. However, when the jaw clamps the workpiece, the workpiece can only be positioned in the distribution direction of the two jaws, resulting in low positioning accuracy of the jaw for the workpiece, so that the workpiece released by the jaw is difficult to align with the predetermined position, affecting subsequent assembly or processing operations. Summary of the Utility Model

[0003] In view of this, the present application provides a clamping mechanism to improve the positioning accuracy of the clamped workpiece.

[0004] An embodiment of the present application provides a clamping mechanism, including a connecting seat, two clamping members, and a clamping driving member. The two clamping members are sequentially arranged on the connecting seat along a first direction, and the two clamping members are configured to respectively clamp opposite sides of the workpiece. At least one clamping member is provided with a mating surface, and the mating surface is configured to stop the workpiece along a second direction to restrict the position of the workpiece relative to the clamping member along the second direction. At least one clamping member is provided with an abutting surface, and the abutting surface is configured to stop the workpiece along a third direction to restrict the position of the workpiece relative to the clamping member along the third direction. The first direction, the second direction, and the third direction intersect pairwise. The clamping driving member is arranged on the connecting seat, and the clamping driving member is connected to at least one clamping member to move the two clamping members closer to and away from each other along the first direction.

[0005] In the above embodiment, when clamping the workpiece, the connecting seat is moved by an external structural member so that the mating surface and the abutting surface are respectively in contact with the workpiece. Then, the clamping driving member moves the two clamping members closer to each other to clamp the workpiece. The two clamping members restrict the position of the workpiece relative to the clamping member in the first direction, the mating surface restricts the position of the workpiece relative to the clamping member in the second direction, and the abutting surface restricts the position of the workpiece relative to the clamping member in the third direction, so that the position of the workpiece relative to the clamping member is restricted in three directions, which can improve the position accuracy of the workpiece relative to the clamping member, and thus can improve the position accuracy of the workpiece released by the clamping mechanism, facilitating subsequent assembly or processing operations of the workpiece.

[0006] In some embodiments of the present application, the abutting surface is provided with an adsorption hole, and the adsorption hole extends along the third direction. The clamping mechanism further includes an adsorbing member, and the adsorbing member is configured to adsorb the workpiece through the adsorption hole.

[0007] In the above embodiments, the adsorbing member adsorbs the workpiece through the adsorption holes, so that the workpiece can be kept in contact with the abutting surface, and the workpiece can be fixed relative to the clamping member, thereby further improving the positioning accuracy of the workpiece.

[0008] In some embodiments of the present application, each clamping member is provided with a connecting portion and a protruding portion. The connecting portion is connected to the connecting seat, and the clamping driving member is configured to connect at least one connecting portion. The protruding portion protrudes from one side of the corresponding connecting portion in the third direction, and the protruding portion is configured to clamp the workpiece. The protruding portion is provided with a limiting surface, and when the protruding portions of the two clamping members clamp the workpiece, the limiting surface is configured to support the workpiece toward the abutting surface in the third direction.

[0009] In the above embodiments, the clamping driving member drives the connecting portion to move, so that the protruding portion moves, so that the two protruding portions clamp the workpiece. The protruding portion is in a protruding shape, which is convenient for the clamping member to clamp a workpiece with a smaller size. The limiting surface can further restrict the workpiece in the third direction, which is beneficial to further improving the positioning accuracy of the workpiece relative to the clamping member.

[0010] In some embodiments of the present application, the limiting surface is provided on one side of the protruding portion along the first direction, and the limiting surface is inclined relative to the third direction.

[0011] In the above embodiments, when the protruding portion clamps the workpiece, the inclined limiting surface contacts the workpiece first, and the limiting surface has a force on the workpiece in the direction toward the abutting surface, which can make the workpiece move toward the abutting surface, so as to facilitate the abutting of the workpiece with the abutting surface.

[0012] In some embodiments of the present application, the protruding portion is provided with a mating surface, and the connecting portion is provided with an abutting surface. The mating surface is connected to the limiting surface.

[0013] In the above embodiments, the mating surface and the limiting surface are adjacent to each other. During the process of clamping the workpiece, moving the connecting seat in the third direction can make the abutting surface contact the workpiece, then moving the connecting seat in the second direction can make the mating surface contact the workpiece, and finally the clamping driving member drives the connecting portion to move, so that the limiting surface can contact the workpiece to further fix the workpiece.

[0014] In some embodiments of the present application, a relief groove is recessed at the intersection of the mating surface and the abutting surface.

[0015] In the above embodiments, the relief groove is provided at the intersection of the mating surface and the abutting surface, so that the part of the connecting portion or the protruding portion at the intersection of the mating surface and the abutting surface is removed, which can reduce the processing requirements for the intersection of the mating surface and the abutting surface, and thus reduce the forming difficulty of the connecting portion and the protruding portion.

[0016] In some embodiments of the present application, the clamping member is provided with a sliding portion, and the connecting seat is provided with a guiding portion, and the sliding portion is slidably connected to the guiding portion along the first direction.

[0017] In the above embodiments, the sliding part and the guiding part are in sliding fit, which can improve the stability of the sliding of the clamping part relative to the connecting seat.

[0018] In some embodiments of the present application, the clamping mechanism further includes a mounting seat and an elastic member. The connecting seat is slidably arranged on the mounting seat along a third direction. The elastic member is arranged between the connecting seat and the mounting seat, and the elastic member is configured to provide an elastic force along the third direction to the connecting seat.

[0019] In the above embodiments, during the process of the mounting seat moving towards the workpiece to be clamped, when the abutting surface abuts against the workpiece, the elastic member can undergo elastic deformation to buffer the acting force of the mounting seat on the connecting seat, thereby reducing the acting force of the abutting surface on the workpiece and reducing the possibility of the workpiece being deformed or damaged due to the pressure from the abutting surface.

[0020] In some embodiments of the present application, the mounting seat is provided with a mounting portion, the mounting portion and / or the connecting seat are provided with insertion holes, one end of the elastic member is inserted into the insertion hole, and both ends of the elastic member respectively abut against the mounting portion and the connecting seat; the mounting seat is provided with a supporting portion, and the supporting portion is configured to support the connecting seat towards the mounting portion along the third direction.

[0021] In the above embodiments, one end of the elastic member is inserted into the insertion hole, and the insertion hole has a limiting effect on the elastic member. The cooperation between the supporting portion and the mounting portion can keep the elastic member in a compressed and deformed state, improve the stability of the fixation of the elastic member relative to the mounting portion and the connecting seat, and reduce the possibility of the connecting seat moving relative to the mounting seat during the movement of the mounting seat. When it is necessary to replace the elastic member, further squeeze the elastic member, and the elastic member can be separated from the insertion hole to remove the elastic member. Squeeze the new elastic member, insert one end of the elastic member into the insertion hole, and then release the elastic member, and both ends of the elastic member can respectively abut against the mounting portion and the connecting seat.

[0022] Some embodiments of the present application further provide a workpiece transfer device, including a transfer mechanism and the clamping mechanism in any of the above embodiments. The connecting seat is connected to the transfer mechanism, and the transfer mechanism is configured to drive the connecting seat to move.

[0023] In the above embodiments, the transfer mechanism is used to drive the connecting seat to move so that the clamping part approaches the workpiece to be clamped. Description of the Drawings

[0059] In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0060] An embodiment of the present application provides a clamping mechanism, including a connecting seat, two clamping members, and a clamping driving member. The two clamping members are sequentially arranged on the connecting seat in a first direction, and the two clamping members are configured to respectively clamp opposite sides of the workpiece. At least one clamping member is provided with a mating surface, and the mating surface is configured to stop the workpiece in a second direction to restrict the position of the workpiece relative to the clamping member in the second direction. At least one clamping member is provided with an abutting surface, and the abutting surface is configured to stop the workpiece in a third direction to restrict the position of the workpiece relative to the clamping member in the third direction. The first direction, the second direction, and the third direction intersect pairwise. The clamping driving member is arranged on the connecting seat, and the clamping driving member is connected to at least one clamping member to move the two clamping members closer to and away from each other in the first direction.

[0061] When clamping the workpiece, the two clamping members restrict the position of the workpiece relative to the clamping member in the first direction, the mating surface restricts the position of the workpiece relative to the clamping member in the second direction, and the abutting surface restricts the position of the workpiece relative to the clamping member in the third direction, so that the position of the workpiece relative to the clamping member is restricted in three directions, which can improve the position accuracy of the workpiece relative to the clamping member, and thus can improve the position accuracy of the workpiece released by the clamping mechanism, facilitating subsequent assembly or processing operations of the workpiece.

[0062] Some embodiments of the present application will be described in detail below with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0063] Refer to Figure 1, an embodiment of the present application provides a clamping mechanism 10, including a connecting seat 11, two clamping members 12, and a clamping driving member 13. The two clamping members 12 are spaced apart and arranged on the connecting seat 11.

[0064] The distribution direction of the two clamping members 12 is the first direction X. Define the second direction Y and the third direction Z, and the first direction X, the second direction Y, and the third direction Z intersect pairwise, and the straight line where the first direction X is located, the straight line where the second direction Y is located, and the straight line where the third direction Z is located are at least distributed in two intersecting planes. In some embodiments, the first direction X, the second direction Y, and the third direction Z are pairwise perpendicular. In some embodiments, the third direction Z is parallel to the gravity direction.

[0065] In some embodiments, both of the two clamping members 12 are slidably arranged on the connecting seat 11 along the first direction X, and the clamping driving member 13 is arranged on the connecting seat 11 and is configured to drive the two clamping members 12 to approach and separate from each other synchronously, so that the two clamping members 12 respectively clamp the opposite sides of a workpiece (not shown in the figure). In some other embodiments, one of the clamping members 12 can be fixed relative to the connecting seat 11, and the other clamping member 12 is connected to the clamping driving member 13, and the clamping driving member 13 drives the corresponding clamping member 12 to approach and move away from the other clamping member 12.

[0066] In some embodiments, the clamping member 12 is provided with a sliding portion 121, and the connecting seat 11 is provided with a guiding portion 111. The sliding portion 121 is slidably connected to the guiding portion 111 along the first direction X. In some embodiments, the sliding portion 121 is a sliding seat, and the guiding portion 111 is a sliding rail, and the sliding portion 121 is slidably engaged with the guiding portion 111. In some embodiments, the sliding portion 121 and the guiding portion 111 are slidably engaged through crossed rollers. In some other embodiments, the sliding portion 121 and the guiding portion 111 are slidably engaged through a sliding groove. The sliding engagement between the sliding portion 121 and the guiding portion 111 can improve the stability of the sliding of the clamping member 12 relative to the connecting seat 11.

[0067] Referring to Figure 1 and Figure 2 , in some embodiments, each clamping member 12 is provided with a connecting portion 122 and a protruding portion 123. The connecting portion 122 is connected to the connecting seat 11, and the protruding portion 123 protrudes along the third direction Z on one side of the corresponding connecting portion 122, and the protruding portion 123 is configured to clamp the workpiece. It can be understood that the protruding portion 123 and the connecting portion 122 are integrally formed. By making the cross-sectional area of the protruding portion 123 smaller than that of the connecting portion 122, it is convenient for the protruding portion 123 to clamp a workpiece with a smaller length or width.

[0068] In some embodiments, the connecting portion 122 is connected to the sliding portion 121 so that the connecting portion 122 can slide relative to the connecting seat 11. In some embodiments, the clamping mechanism 10 is an electric gripper, the clamping driving member 13 is a motor, the motor of the clamping driving member 13 is fixedly connected to the connecting seat 11, and the motor of the clamping driving member 13 drives the two connecting portions 122 to move through a gear-rack structure. In other embodiments, the clamping mechanism 10 may be a pneumatic gripper, the clamping driving member 13 is a cylinder, the cylinder of the clamping mechanism 10 is fixedly connected to the connecting seat 11, and the piston of the cylinder of the clamping structure 10 is connected to the connecting portion 122 of the clamping member 12 to drive the two connecting portions 122 to move.

[0069] Referring Figure 2 and Figure 3 , in some embodiments, both of the two clamping members 12 are provided with a mating surface 124. It can be understood that the protruding portions 123 of the two clamping members 12 are both provided with a mating surface 124. The mating surface 124 is configured to stop the workpiece along the second direction Y to restrict the position of the workpiece relative to the clamping member 12 along the second direction Y.

[0070] In some embodiments, the side wall on one side of the protruding portion 123 along the second direction Y forms the mating surface 124, and the side wall of the protruding portion 123 along the first direction X and facing the other protruding portion 123 forms a clamping surface 126, and the clamping surface 126 is configured to abut against the workpiece. In other embodiments, it may also be that only the protruding portion 123 of one of the clamping members 12 is provided with a mating surface 124. In other embodiments, the mating surface 124 may be provided on the connecting portion 122.

[0071] In some embodiments, both of the two clamping members 12 are provided with an abutting surface 125. It can be understood that the connecting portions 122 of the two clamping members 12 are both provided with an abutting surface 125, and the abutting surface 125 is configured to stop the workpiece along the third direction Z to restrict the position of the workpiece relative to the clamping member 12 along the third direction Z.

[0072] In some embodiments, the side wall of the connecting portion 122 connected to the protruding portion 123 forms the abutting surface 125. In other embodiments, the connecting portion 122 is provided with an abutting block, and the side wall of the abutting block along the third direction Z and close to the protruding portion 123 forms the abutting surface 125. In other embodiments, it may be that only the connecting portion 122 of one of the clamping members 12 is provided with an abutting surface 125. In other embodiments, the abutting surface 125 may be provided on the protruding portion 123.

[0073] In some embodiments, the abutment surface 125 is provided with suction holes 1251 extending along the third direction Z. The clamping mechanism 10 further includes a suction member 14 configured to suction the material through the suction holes 1251. In some embodiments, the suction holes 1251 extend through the sidewall of the connecting portion 122. The suction member 14 is a negative pressure suction head secured to the connecting portion 122, with the interior of the suction head communicating with the interior of the suction holes 1251. The negative pressure suction head creates a negative pressure within the suction holes 1251, thereby causing the material to be suctioned to the abutment surface 125. Furthermore, the connecting portion 122 not only serves to position the material through the abutment surface 125 but also serves as a mounting for the suction member 14, allowing the suction member 14 to suction the material through the suction holes 1251. This facilitates a compact structure for the clamping member 12 and reduces the possibility of interference with other materials during clamping.

[0074] In other embodiments, the adsorption member 14 is an electromagnet, which is embedded in the adsorption hole 1251, and the material of the corresponding material is a ferromagnetic material. When the electromagnet is energized, the electromagnet can adsorb the material so that the material abuts against the adsorption member 14. The adsorption member 14 adsorbs the material, which can keep the material in abutment with the abutment surface 125 and can keep the material fixed relative to the clamping member 12, thereby further improving the positioning accuracy of the material. Figure 3 In some embodiments, the raised portion 123 is provided with a limiting surface 1231. When the raised portions 123 of the two clamping members 12 clamp the workpiece, the limiting surface 1231 is configured to support the workpiece toward the abutting surface 125 along the third direction Z. The limiting surface 1231 can further constrain the workpiece in the third direction Z, thereby further improving the positioning accuracy of the workpiece relative to the clamping members 12.

[0075] In some embodiments, the sidewall of the protrusion 123 along the third direction Z and away from one end of the corresponding connection portion 122 is connected to a limit block 1232. The limit block 1232 forms a limit surface 1231 along the third direction Z and toward the sidewall of the corresponding connection portion 122. In some embodiments, the limit block 1232 and the protrusion 123 are integrally formed. In other embodiments, the protrusion 123 may define a limit groove. The limit groove passes through the sidewall of the protrusion 123 along the first direction X and toward the other protrusion 123. The limit surface 1231 is formed along the inner wall of the protrusion 123 along the third direction Z and toward the corresponding connection portion 122. The dotted line in the figure is used to separate the limit block 1232 and the raised portion 123. It should be noted that the dividing line between the limit block 1232 and the raised portion 123 is not limited to the dotted line in the figure, as long as a limit surface 1231 can be formed on the limit block 1232 to receive the material in the third direction Z, and the raised portion 123 can clamp the material.

[0076] In some embodiments, the limiting surface 1231 is inclined relative to the third direction Z. When the protruding portion 123 clamps the workpiece, the inclined limiting surface 1231 contacts the workpiece first. The limiting surface 1231 has a force acting on the workpiece in the direction towards the abutting surface 125, which can move the workpiece towards the abutting surface 125, thus facilitating the abutment of the workpiece against the abutting surface 125. In some embodiments, the inclined limiting surface 1231 is shaped to conform to the side wall of the workpiece to be clamped.

[0077] In some embodiments, the limiting surface 1231 is disposed adjacent to the mating surface 124. It can be understood that the limiting surface 1231 and the mating surface 124 are perpendicular to each other. Exemplarily, the workpiece has a protruding structure extending along the first direction X. When clamping the workpiece, after the abutting surface 125 abuts against the workpiece, the connecting seat 11 is moved along the second direction Y. After the mating surface 124 abuts against the side wall of the protruding structure of the workpiece, the clamping driving member 13 can then drive the connecting seat 11 to move, so that the clamping surface 126 and the limiting surface 1231 of the protruding portion 123 can abut against the side wall of the workpiece to clamp the workpiece.

[0078] In some embodiments, the connecting portion 122 is provided with a relief groove 1221, and the relief groove 1221 is recessed at the intersection of the mating surface 124 and the abutting surface 125. On the one hand, the relief groove 1221 can reduce the processing difficulty of the portion of the connecting portion 122 located between the mating surface 124 and the abutting surface 125. On the other hand, the relief groove 1221 can avoid some structures on the workpiece, so as to facilitate the full abutment of the workpiece against the abutting surface 125.

[0079] Referring to Figure 4 and Figure 5 , in some embodiments, the clamping mechanism 10 further includes a mounting seat 15 and an elastic member 16. The connecting seat 11 is slidably disposed along the third direction Z on the mounting seat 15. The elastic member 16 is disposed between the connecting seat 11 and the mounting seat 15, and the elastic member 16 is configured to provide an elastic force to the connecting seat 11 along the third direction Z. In some embodiments, the connecting seat 11 is slidably connected to the mounting seat 15 through a slide rail.

[0080] During the process of the mounting seat 15 moving towards the workpiece to be clamped, when the abutting surface 125 abuts against the workpiece, the elastic member 16 can undergo elastic deformation to buffer the force of the mounting seat 15 on the connecting seat 11, thereby reducing the force of the abutting surface 125 on the workpiece and reducing the possibility of the workpiece being deformed or damaged due to the pressure from the abutting surface 125.

[0081] In some embodiments, the mounting base 15 is provided with a mounting portion 151. The mounting portion 151 and the connecting base 11 are provided with insertion holes 1511. The two ends of the elastic member 16 are respectively inserted into the insertion hole 1511 of the mounting portion 151 and the insertion hole 1511 of the connecting base 11. The elastic member 16 is in a state of compressive deformation, and the two ends of the elastic member 16 are respectively abutted against the mounting portion 151 and the connecting base 11. The mounting base 15 is provided with a supporting portion 152, and the supporting portion 152 is configured to support the connecting base 11 toward the mounting portion 151 along the third direction Z. It can be understood that both the mounting portion 151 and the supporting portion 152 are in a block shape, and both the mounting portion 151 and the supporting portion 152 are integrally formed with the mounting base 15. A part of the structure of the connecting base 11 is located between the mounting portion 151 and the supporting portion 152, and the elastic member 16 is located between the connecting base 11 and the mounting portion 151. In some other embodiments, one of the mounting portion 151 and the connecting base 11 may be provided with the insertion hole 1511.

[0082] In some embodiments, the elastic member 16 includes a helical spring. The insertion hole 1511 of the connecting base 11 is a blind hole. The insertion hole 1511 of the mounting portion 151 is a through threaded hole. The mounting portion 151 is provided with a fixing stud 1512, and the fixing stud 1512 is in threaded cooperation with the insertion hole 1511 of the mounting portion 151. After both ends of the elastic member 16 are inserted into the corresponding insertion holes 1511, the fixing stud 1512 is installed, and the fixing stud 1512 is abutted against the corresponding end of the elastic member 16, so that the elastic member 16 is abutted against the mounting portion 151 through the fixing stud 1512. After the elastic member 16 is pressed by the fixing stud 1512, it undergoes elastic compressive deformation, so that the connecting base 11 is tightly abutted against the supporting portion 152. In some other embodiments, the elastic member 16 may be a gas spring or a hydraulic spring.

[0083] In some embodiments, the working mode of the clamping mechanism 10 is as follows:

[0084] When clamping a workpiece, move the mounting base 15. First, make the mating surface 124 abut against the workpiece to restrict the position of the workpiece relative to the clamping member 12 in the second direction Y; then make the abutting surface 125 abut against the workpiece to restrict the position of the workpiece relative to the clamping member 12 in the third direction Z; then, the clamping driving member 13 makes the two clamping members 12 approach each other to clamp the workpiece, so as to restrict the position of the workpiece relative to the clamping member 12 in the first direction X, so that the position of the workpiece relative to the clamping member 12 is restricted in three directions. After the mounting base 15 is moved to a specified position, the clamped workpiece can be accurately aligned with a predetermined position, so as to improve the position accuracy of the workpiece released by the clamping member 12, thereby facilitating subsequent assembly or processing operations of the workpiece.

[0085] Some embodiments of the present application further provide a workpiece transfer device, which includes a transfer mechanism (not shown in the figure) and the clamping mechanism 10 provided in any of the above embodiments. The connecting seat 11 is connected to the transfer mechanism, and the transfer mechanism is configured to drive the connecting seat 11 to move. It can be understood that the mounting seat 15 is connected to the transfer mechanism so that the connecting seat 11 is connected to the transfer mechanism.

[0086] In some embodiments, the transfer mechanism is a multi-axis industrial robot. In other embodiments, the transfer mechanism can be an electric push rod, a linear motor, or other structural members capable of driving the connecting seat 11 to move.

[0087] In addition, those of ordinary skill in the art of the present technology should recognize that the above embodiments are only used to illustrate the present application and are not intended to limit the present application. As long as appropriate changes and variations made to the above embodiments fall within the scope of the spirit of the present application, they fall within the scope of the disclosure of the present application.
