Description

Technical Field

[0001] The present application relates to the technical field of fixture positioning, and in particular to a clamping and limiting mechanism. Background Art

[0002] When CNC machine tools process materials, the materials need to be installed on the jig so that the materials are not easily moved during the processing. In the related art, when installing materials, the materials are first loaded into the installation space in the jig, and then the materials need to be clamped with one hand to pre-fix the materials, and then the materials are locked on the jig with screws to fix the materials on the jig. After installation, they can be processed by CNC.

[0003] However, the manual pre-fixing method of the material is inconvenient to operate and causes poor consistency in repeated clamping of the material. During batch processing, the loading position of the material is different and the product size is unstable. Utility Model Content

[0004] In view of this, the present application provides a clamping and limiting mechanism, which can facilitate the pre-fixation of materials on the fixture and improve the consistency of repeated clamping of materials.

[0005] An embodiment of the present application provides a clamping and limiting mechanism, which includes a bearing member and a limiting assembly. The bearing member has a bearing surface and a mounting groove penetrating the bearing surface, and the bearing surface is used to bear a jig containing materials. The limiting assembly includes a rotating member, and the rotating member includes a first extension block and a second extension block connected to each other; the rotating member is used for, when the jig is not carried, the first extension block partially protrudes above the bearing surface through the mounting groove. When the jig is carried, the rotating member is used for, when the jig is carried, the first extension block is accommodated in the mounting groove and is flush with the bearing surface, and the second extension block turns from an inclined state to a vertical state and pushes the material in the jig to position the material on the jig.

[0006] In the above-mentioned clamping and limiting mechanism, when the jig is placed on the carrier, the jig applies pressure to the first extension block protruding from the carrier surface to drive the rotating member to rotate. At this time, the rotating member is in a stressed state, and the second extension block can push the material to make the material pre-positioned on the jig, so that when the material is further fixed later, the material is not easy to move on the jig. When the jig is removed from the carrier, the jig releases the pressure on the first extension block so that the rotating member rotates under the gravity of the second extension block. At this time, the rotating member is in an unstressed state, so that part of the first extension block protrudes from the carrier surface again to allow the next jig to be placed. When batch processing materials, the rotating member can fix the material by rotating, thereby improving the consistency of repeated clamping of the material and improving the dimensional stability of the processed material.

[0007] In at least one embodiment, the limiting assembly further includes a pushing member, which is connected to the second extension block, and the second extension block drives the pushing member to push the material in the fixture.

[0008] In the above embodiment, the pushing member can rotate with the second extension block to a position away from the material, thereby releasing the force on the material, so that the jig can be removed from the carrier. The second extension block can push the material through the pushing member to position the material between the pushing member and the jig, so that the material is not easy to move on the jig.

[0009] In at least one embodiment, the limiting assembly also includes a connecting member and an elastic member, the second extension block is provided with a mounting hole, the connecting member is slidably arranged in the mounting hole along a first direction, the first direction is parallel to the bearing surface, and the connecting member is connected to the pushing member; the elastic member is sleeved on the connecting member, and one end of the elastic member is connected to the second extension block, and the other end is connected to the pushing member.

[0010] In the above embodiment, when the push member applies force to the material, the elastic member generates compression deformation on the connecting member to have an extension drive, so that the elastic member can apply force to the push member toward the material, so that the push member can push the material tightly. In addition, the setting of the elastic member allows the push member to have floating space, reducing the situation where the material is damaged due to excessive force applied by the push member to the material.

[0011] In at least one embodiment, the limiting assembly further includes a supporting member located below the pushing member, the supporting member is connected to the second extension block, and the supporting member is used to support the pushing member.

[0012] In the above embodiment, the pushing member is affected by its own gravity during the process of sliding with the connecting member, and the supporting member can support the pushing member, which is beneficial to improve the stability of the pushing member sliding along the first direction and reduce the possibility of the pushing block tilting downward due to long-term use.

[0013] In at least one embodiment, the pushing member includes a pushing portion and a connecting portion connected to each other, the connecting portion is connected to the connecting member and is located below the pushing portion, and the connecting portion has an avoidance notch on a side facing the fixture, and the connecting portion can avoid the fixture through the avoidance notch when rotating.

[0014] In the above-mentioned embodiment, the setting of the avoidance notch can, on the one hand, reduce the weight of the pushing member and reduce the risk of the pushing member tilting downward due to gravity; on the other hand, it can increase the overall rotation space of the pushing member during rotation, avoid the fixture, reduce friction and collision with the fixture, and improve the smoothness of the movement of the clamping limit mechanism.

[0015] In at least one embodiment, the clamping and limiting mechanism further includes a limiting column, which is disposed on the bearing member and extends along a second direction for plugging and mating with a hole at the bottom of the fixture, wherein the second direction is perpendicular to the bearing surface.

[0016] In the above embodiment, when the jig is placed on the carrier, the limiting column is inserted into the hole at the bottom of the jig along the second direction to limit the movement of the jig on the carrier along the first direction, thereby improving the stability of the connection between the jig and the carrier, thereby further improving the stability of the material pre-fixation on the jig.

[0017] In at least one embodiment, the clamping and limiting mechanism also includes a positioning component, which includes a pressing member and a driving member. The pressing member is arranged on one side of the supporting member, and the pressing member is connected to the driving member. The driving member is used to drive the pressing member to move so that the pressing member applies a force to the fixture toward the supporting surface.

[0018] In the above-mentioned embodiment, by driving the pressing member through the driving member, the pressing member can apply a force to the jig so that the jig can be pressed against the bearing surface, thereby improving the stability of the jig installed on the bearing member, so that when the material is subsequently locked, the material is not easy to move with the jig.

[0019] In at least one embodiment, the first extension block has a stepped surface, the inner wall of the mounting groove facing the stepped surface is a limiting surface, the stepped surface is constructed to form an avoidance space with the limiting surface, and part of the stepped surface is used to rotate toward the avoidance space until it abuts against the limiting surface.

[0021] In at least one embodiment, the stepped surface includes a first plane and a second plane connected to each other, the first plane is located above the second plane, and the minimum distance between the second plane and the limiting surface is greater than the maximum distance between the first plane and the limiting surface.

[0022] In the above embodiment, when the rotating member rotates from the second position to the first position, the first plane portion rotates out of the installation slot first, and then the second plane rotates in the direction out of the installation slot. The clearance space between the second plane and the limiting surface is larger than the clearance space between the first plane and the limiting surface, thereby facilitating the rotation of the second plane and reducing the collision between the second plane and the limiting surface.

[0023] In at least one embodiment, the supporting member includes a base plate and a supporting column, the base plate has a mounting groove, the supporting column is disposed on the base plate and protrudes above the base plate, and the supporting column has a bearing surface.

[0024] In the above-mentioned embodiment, the provision of the support column can reduce the area of ​​the bearing surface, reduce the contact area between the bearing member and the jig, and allow a gap to exist between the lower surface of the jig and the upper surface of the base plate. The gap can avoid material debris attached to the lower surface of the jig, thereby facilitating the stable placement of the jig on the bearing member. BRIEF DESCRIPTION OF THE DRAWINGS

[0071] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0072] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0073] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0074] It should be noted that the thickness, length, width and other dimensions of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device are only exemplary and should not constitute any limitation to the present application.

[0075] When CNC machine tools process materials, the materials need to be installed on the jig so that the materials are not easily moved during the processing. In the related art, when installing materials, the materials are first loaded into the installation space in the jig, and then the materials need to be clamped with one hand to pre-fix the materials, and then the materials are locked on the jig with screws to fix the materials on the jig. After installation, they can be processed by CNC.

[0076] However, the manual pre-fixing method of the material is inconvenient to operate and causes poor consistency in repeated clamping of the material. During batch processing, the loading position of the material is different and the product size is unstable.

[0077] An embodiment of the present application provides a clamping and limiting mechanism, which includes a bearing member and a limiting assembly. The bearing member has a bearing surface and a mounting groove penetrating the bearing surface, and the bearing surface is used to bear a jig containing materials. The limiting assembly includes a rotating member, and the rotating member includes a first extension block and a second extension block connected to each other; the rotating member is used for, when the jig is not carried, the first extension block partially protrudes above the bearing surface through the mounting groove. When the jig is carried, the rotating member is used for, when the jig is carried, the first extension block is accommodated in the mounting groove and is flush with the bearing surface, and the second extension block turns from an inclined state to a vertical state and pushes the material in the jig to position the material on the jig.

[0078] In the above-mentioned clamping and limiting mechanism, when the jig is placed on the carrier, the jig applies pressure to the first extension block protruding from the carrier surface to drive the rotating member to rotate. At this time, the rotating member is in a stressed state, and the second extension block can push the material to make the material pre-positioned on the jig, so that when the material is further fixed later, the material is not easy to move on the jig. When the jig is removed from the carrier, the jig releases the pressure on the first extension block so that the rotating member rotates under the gravity of the second extension block. At this time, the rotating member is in an unstressed state, so that part of the first extension block protrudes from the carrier surface again to allow the next jig to be placed. When batch processing materials, the rotating member can fix the material by rotating, thereby improving the consistency of repeated clamping of the material and improving the dimensional stability of the processed material.

[0079] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0080] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a clamping and limiting mechanism 100, which is used to pre-position a material 300 to a fixture 200. The clamping and limiting mechanism 100 includes a carrier 10 and a limiting assembly 20. The carrier 10 is used to carry the fixture 200 and cooperate with the limiting assembly 20 to pre-position the fixture 200.

[0081] See also Figure 1 and Figure 2 In some embodiments, the fixture 200 includes a body 201, a stopper 202 and a screw (not shown), and the stopper 202 and the body 201 form an installation space for accommodating the material 300. After the material 300 is installed in the installation space, the body 201 containing the material 300 is placed on the carrier 10, and the movement of the material 300 in the installation space is limited by the cooperation of the stopper 202 and the stopper assembly 20 to achieve the pre-positioning of the material 300, and then the screw is installed on the stopper 202, so that the screw locks the stopper 202 and the body 201, and the material 300 is fixed on the fixture 200, and after being fixed, it can be processed by the CNC machine tool.

[0082] See also Figures 2 to 4 In some embodiments, the carrier 10 has a carrier surface 11 and a mounting groove 12 penetrating the carrier surface 11, and the carrier surface 11 is used to carry the fixture 200 loaded with the material 300. The limiting assembly 20 includes a rotating member 21, and the rotating member 21 includes a first extension block 211 and a second extension block 212 connected to each other; Figure 4 As shown, the rotating member 21 is used to make the first extension block 211 partially protrude above the bearing surface 11 through the mounting groove 12 when the fixture 200 is not supported. Figure 2 and Figure 3As shown, the rotating member 21 is used to support the jig 200, the first extension block 211 is accommodated in the installation groove 12 and is flush with the supporting surface 11, and the second extension block 212 is turned from an inclined state to a vertical state and pushes the material 300 in the jig 200 to position the material 300 on the jig 200.

[0083] In some embodiments, the rotating member 21 is in a first position when not bearing the jig 200 and is not under stress. The rotating member 21 is in a second position when bearing the jig 200 and can rotate relative to the bearing member 10 between the first position and the second position. Figure 2 and Figure 3 The rotating member 21 is in the second position, Figure 4 The rotating member 21 is in the first position.

[0084] The second extension block 212 is used to drive the rotating member 21 to rotate to the first position by gravity, and the first extension block 211 located at the first position partially protrudes above the bearing surface 11 through the mounting groove 12. The portion of the first extension block 211 protruding from the bearing surface 11 is used to be pressed by the jig 200 placed on the bearing surface 11, so that the rotating member 21 rotates from the first position to the second position, and the second extension block 212 rotated to the second position pushes the material 300 in the jig 200, so that the material 300 is positioned on the jig 200.

[0085] During the process of placing the jig 200 on the carrier 10, the jig 200 applies pressure to the first extension block 211 protruding from the carrier surface 11 to drive the rotating member 21 to rotate from the first position to the second position. After the rotating member 21 rotates to the second position, the second extension block 212 can push the material 300 so that the material 300 is pre-positioned on the jig 200, so that when the material 300 is further fixed later, the material 300 is not easy to move on the jig 200. During the process of removing the jig 200 from the carrier 10, the jig 200 releases the pressure on the first extension block 211, so that the rotating member 21 rotates to the first position under the gravity of the second extension block 212, so that the part of the first extension block 211 protrudes from the carrier surface 11 again, so as to place the next jig 200. When batch processing materials 300, the rotating member 21 can fix the materials 300 by rotating between the first position and the second position, thereby improving the consistency of repeated clamping of the materials 300 and improving the dimensional stability of the processed materials 300.

[0086] See also Figure 1 and Figure 3In some embodiments, the carrier 10 includes a bottom plate 13 and a support column 14, the bottom plate 13 has a mounting groove 12, the support column 14 is disposed on the bottom plate 13 and protrudes above the bottom plate 13, and the support column 14 has a bearing surface 11. When the fixture 200 is placed on the carrier 10, the bottom of the body 201 contacts the support column 14.

[0087] The setting of the support column 14 can reduce the area of ​​the bearing surface 11, reduce the contact area between the bearing member 10 and the main body 201 of the fixture 200, and make a gap between the lower surface of the main body 201 and the upper surface of the bottom plate 13. The gap can avoid the debris of the material 300 attached to the lower surface of the fixture 200, thereby facilitating the stable placement of the fixture 200 on the bearing member 10.

[0088] Furthermore, a plurality of support columns 14 are provided, and the plurality of support columns 14 jointly support the fixture 200 .

[0089] In other embodiments, the carrier 10 includes a bottom plate 13, the upper surface of the bottom plate 13 is a bearing surface 11, and when the jig 200 is placed on the carrier 10, the bottom of the body 201 contacts the bearing surface 11. At this time, when the rotating member 21 is pressed by the jig 200, the upper surface of the second extension block 212 and the upper surface of the bottom plate 13 are located in the same plane to support the jig 200 together with the upper surface of the bottom plate 13. The jig 200 is supported by the upper surface of the second extension block 212 and the upper surface of the bottom plate 13, which is conducive to maintaining the stability of the jig 200.

[0090] See also Figure 1 In some embodiments, the carrier 10 further includes a support frame 15 , and the base plate 13 is disposed above the support frame 15 . The support frame 15 can support the base plate 13 and raise the height of the base plate 13 to facilitate placing the fixture 200 on the carrier 10 .

[0091] See also Figure 3 and Figure 5 In some embodiments, the first extension block 211 and the second extension block 212 are substantially vertical, that is, the first extension block 211 and the second extension block 212 are substantially L-shaped. When the rotating member 21 is located at the second position, the first extension block 211 extends along the first direction X, and the second extension block 212 extends along the second direction Y. The first direction X is a horizontal direction, that is, the first direction X is parallel to the bearing surface 11, and the second direction Y is a vertical direction, that is, the second direction Y is perpendicular to the bearing surface 11.

[0092] In some embodiments, the rotation angle range of the rotating member 21 is 0 degrees to 60 degrees, that is, when the rotation angle of the rotating member 21 is defined as 0 degrees when it is in the second position, the rotation angle of the rotating member 21 when it is in the first position can be set to any angle between 0 degrees and 60 degrees. For example, when the rotating member 21 is in the first position, the rotation angle is any one of 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, and 55 degrees. When the rotation angle range is 0 degrees to 60 degrees, it is not only conducive to the first extension block 211 to rotate to a state protruding from the bearing surface 11 so as to eject the fixture 200 from the bearing surface 11, but also conducive to reducing the situation where the rotating member 21 is over-turned and the fixture 200 is difficult to be placed on the bearing surface 11.

[0093] See also Figure 5 and Figure 6 In some embodiments, the first extension block 211 has a stepped surface 2111, and the inner wall of the mounting groove 12 facing the stepped surface 2111 is a limiting surface 121, and the limiting surface 121 extends along the second direction Y. The stepped surface 2111 is configured to form an escape space 30 with the limiting surface 121, and a portion of the stepped surface 2111 is used to rotate toward the escape space 30 until it abuts against the limiting surface 121. When the limiting surface 121 abuts against the stepped surface 2111, the second extension block 212 can be restricted from continuing to rotate toward the direction of the protruding bearing surface 11.

[0094] For example, when the rotating member 21 is in the second position, an avoidance space 30 is formed between the limiting surface 121 and the step surface 2111; the direction in which the rotating member 21 rotates from the second position to the first position is the first rotation direction R; when the rotating member 21 is in the first position, the step surface 2111 abuts against the limiting surface 121 to limit the second extension block 212 from continuing to rotate in the first rotation direction R.

[0095] The formation of the avoidance space 30 provides a rotation space for the first extension block 211, so that when the rotating member 21 rotates between the first position and the second position, the step surface 2111 is not easy to collide and rub against the limiting surface 121, so that the first rotating member 21 is not easily damaged; when the rotating member 21 is in the first position, the limiting surface 121 can limit the second extension block 212 from rotating in the first rotation direction R, so that the rotating member 21 stays in the first position, thereby facilitating the next fixture 200 to be installed on the carrier 10.

[0096] See also Figure 5 and Figure 6 In some embodiments, the step surface 2111 includes a first plane 2112 and a second plane 2113 connected to each other, the first plane 2112 is located above the second plane 2113, and the minimum distance between the second plane 2113 and the limiting surface 121 is greater than the maximum distance between the first plane 2112 and the limiting surface 121.

[0097] When the rotating member 21 rotates from the second position to the first position, the first plane 2112 rotates out of the installation slot 12 first, and then the second plane 2113 rotates in the direction out of the installation slot 12. The avoidance space 30 between the second plane 2113 and the limiting surface 121 is larger than the avoidance space 30 between the first plane 2112 and the limiting surface 121, which is conducive to the rotation of the second plane 2113 and reduces the collision between the second plane 2113 and the limiting surface 121.

[0098] In some embodiments, when the rotating member 21 is in the second position, the first plane 2112 and the limiting surface 121 are both vertical planes, and the second plane 2113 is also a vertical plane. In other embodiments, the limiting surface 121 is a vertical plane, and the first plane 2112 and the second plane 2113 are inclined planes.

[0099] See also Figure 3 and Figure 5 In some embodiments, the rotating member 21 includes a rotating shaft 213, both ends of which are rotatably mounted on the base plate 13 and partially located in the mounting groove 12, and the first extension block 211 is installed on the portion of the rotating shaft 213 located in the mounting groove 12, so that the rotating member 21 is rotatably connected to the base plate 13 through the rotating shaft 213.

[0100] See also Figures 2 to 4 In some embodiments, the limiting assembly 20 further includes a pushing member 22, which is connected to a second extension block 212. When the rotating member 21 rotates from the first position to the second position, the second extension block 212 rotates to the second position to drive the pushing member 22 to push the material 300 in the fixture 200; when the rotating member 21 rotates from the second position to the first position, the second extension block 212 drives the pushing member 22 away from the material 300 in the fixture 200. When the pushing member 22 pushes the material 300, the material 300 is located between the limiting block 202 and the pushing member 22, so as to pre-fix the material 300.

[0101] When the rotating member 21 is located at the first position, the pushing member 22 rotates with the second extension block 212 to a position away from the material 300, thereby releasing the force applied to the material 300, so that the jig 200 can be removed from the carrier 10. When the rotating member 21 is located at the second position, the second extension block 212 pushes the material 300 through the pushing member 22 to position the material 300 between the pushing member 22 and the jig 200, so that the material 300 is not easy to move on the jig 200.

[0102] See also Figure 5 and Figure 6In some embodiments, the limiting assembly 20 further includes a connecting member 23 and an elastic member 24. The second extension block 212 is provided with a mounting hole 2121. The connecting member 23 is slidably disposed in the mounting hole 2121 along the first direction X. The connecting member 23 is connected to the pushing member 22. The elastic member 24 is sleeved on the connecting member 23, and one end of the elastic member 24 is connected to the second extension block 212, and the other end is connected to the pushing member 22. When the pushing member 22 pushes the material 300, the pushing member 22 drives the connecting member 23 to slide in a direction away from the material 300 under the reaction force of the material 300, so that the elastic member 24 is compressed between the pushing member 22 and the second extension block 212.

[0103] When the push member 22 applies force to the material 300, the elastic member 24 generates compression deformation on the connecting member 23 to have an extension drive, so that the elastic member 24 can apply force to the push member 22 toward the material 300, so that the push member 22 can push the material 300 tightly. In addition, the setting of the elastic member 24 allows the push member 22 to have floating space, reducing the situation where the push member 22 applies too much force to the material 300 and damages the material 300.

[0104] In some embodiments, the elastic member 24 is a spring; in other embodiments, the elastic member 24 may also be an elastically deformable component such as an elastic rubber sleeve.

[0105] See also Figures 4 to 6 In some embodiments, the limiting assembly 20 further includes a support member 25 , which is connected to the second extension block 212 and is located below the pushing member 22 , and the support member 25 is used to support the pushing member 22 .

[0106] When the push member 22 slides with the connecting member 23, it is affected by its own gravity, and the support member 25 can support the push member 22, thereby facilitating the stability of the push member 22 sliding along the first direction X and reducing the possibility of the push member 22 tilting downward due to long-term use.

[0107] Specifically, in some embodiments, the support member 25 is a pin, one end of which is connected to the second extension block 212, and the other end of which extends toward the material 300. The number of the pin may be one or more.

[0108] See also Figures 4 to 6In some embodiments, the pushing member 22 includes a pushing portion 221 and a connecting portion 222 that are connected to each other. The connecting portion 222 is connected to the connecting member 23 and is located below the pushing portion 221. The connecting portion 222 has an avoidance notch 223 on the side facing the fixture 200. When the connecting portion 222 rotates, it can avoid the fixture 200 through the avoidance notch 223. When the rotating member 21 is in the second position, the pushing portion 221 pushes the material 300 to position the material 300 on the fixture 200, and the support member 25 is supported below the connecting portion 222.

[0109] The setting of the avoidance notch 223 can, on the one hand, reduce the weight of the pushing member 22 and reduce the risk of the pushing member 22 tilting downward due to gravity; on the other hand, it can increase the overall rotation space of the pushing member 22 during rotation, avoid the fixture 200, reduce friction and collision with the fixture 200, and improve the smoothness of the movement of the clamping limit mechanism 100.

[0110] In some embodiments, the fixture 200 can be installed with multiple materials 300, and multiple limiting components 20 are provided, and each material 300 corresponds to a limiting component 20, so that the clamping and limiting mechanism 100 can pre-fix multiple materials 300 at the same time.

[0111] See also Figure 1 and Figure 2 In some embodiments, the position limiting components 20 are provided in multiple groups, each group of the position limiting components 20 includes two position limiting components 20, and the two position limiting components 20 in each group are arranged opposite to each other. When the jig 200 is placed on the bearing surface 11, the two position limiting components 20 in the same group can be simultaneously subjected to the pressure of the jig 200 and rotated from the first position to the second position; when the jig 200 is taken out from the bearing surface 11, the two position limiting components 20 in the same group can simultaneously rotate from the second position to the first position, so as to wait for the next jig 200 to be placed on the bearing surface 11, thereby improving the fixing efficiency of the material 300.

[0112] See also Figure 3 In some embodiments, the clamping and limiting mechanism 100 further includes a limiting column 40 , which is disposed on the carrier 10 . The limiting column 40 extends along the second direction Y and is used to be plugged into and matched with a hole at the bottom of the fixture 200 .

[0113] When the jig 200 is placed on the carrier 10, the limiting column 40 is inserted into the hole at the bottom of the jig 200 along the second direction Y to limit the movement of the jig 200 on the carrier 10 along the first direction X, thereby improving the stability of the connection between the jig 200 and the carrier 10, thereby further improving the stability of the pre-fixation of the material 300 on the jig 200.

[0114] In some embodiments, at least two limiting posts 40 are provided, and at least two limiting posts 40 can simultaneously position the fixture 200 to limit the translation and rotation of the fixture 200 .

[0115] See also Figure 1 and Figure 7 In some embodiments, the clamping and limiting mechanism 100 also includes a positioning assembly 50, the positioning assembly 50 includes a holding member 51 and a driving member 52, the holding member 51 is arranged on one side of the carrier 10, the holding member 51 is connected to the driving member 52, and the driving member 52 is used to drive the holding member 51 to move so that the holding member 51 can apply a force to the fixture 200 toward the bearing surface 11.

[0116] By driving the pressing member 51 through the driving member 52, the pressing member 51 can apply a force to the jig 200 so that the jig 200 can be pressed against the bearing surface 11, thereby improving the stability of the jig 200 installed on the bearing member 10, so that when the material 300 is subsequently locked, the material 300 is not easy to move with the jig 200.

[0117] In some embodiments, the driving member 52 is a rotary downward pressing cylinder, which is used to drive the pressing member 51 to rotate and rise and fall. When it is necessary to press down the jig 200, the pressing member 51 is first rotated to the top of the jig 200, and then moved downward to press the jig 200. When the jig 200 is unlocked, the pressing member 51 is first driven to rise, and then driven to rotate, so that the pressing member 51 is away from the top of the jig 200.

[0118] See also Figure 1 and Figure 7 In some embodiments, a plurality of positioning assemblies 50 are provided. For example, two positioning assemblies 50 are provided, and the two positioning assemblies 50 are arranged opposite to each other, and are used to simultaneously press and fix the fixture 200 to improve the stability of the fixture 200 on the carrier 10.

[0119] See also Figure 1 and Figure 7 In some embodiments, the positioning assembly 50 further includes a handle 53 , which is connected to the driving member 52 and mounted on the support frame 15 . The handle 53 is manually manipulated to drive the holding member 51 to move.

[0120] In addition, those skilled in the art may also make other changes in the present application. Of course, these changes made based on the present application should be included in the scope disclosed in the present application.
