Abstract
Description
Technical Field
[0001] The present application relates to the technical field of mechanical manufacturing, and particularly relates to a clamping fixture. Background Art
[0002] In the production process of materials, process steps such as marking, laser engraving, or inkjet printing of materials are often involved. Therefore, operations of loading materials onto corresponding equipment and unloading materials from corresponding equipment are often required. For a large number of materials, if the manual loading and unloading method is used one by one each time, the overall production efficiency of the materials will be low, and at the same time, the consumption of manpower is relatively large. Each material needs to be placed in the corresponding clamping position separately, and during actual operation, production personnel still need to align the materials with the clamping positions one by one. Therefore, there is still room for improvement in the production efficiency of materials. Summary of the Utility Model
[0003] In view of this, the present application provides a clamping fixture that can improve the loading efficiency of materials and the production efficiency.
[0004] Some embodiments of the present application provide a clamping fixture, including a substrate, a positioning mechanism, and a fixing mechanism. At least two material grooves are provided on the top of the substrate and are distributed along a first direction. The positioning mechanism includes a movable component; wherein, the movable component is arranged above the material groove and is movably connected to the substrate, so that the movable component can move relative to the substrate along the first direction. At least two sets of first-direction material pushing parts are provided on the side of the movable component protruding towards the material groove, so that when the movable component moves, the materials are pushed towards the side wall of the material groove in the first direction. The fixing mechanism defines the relative movement between the movable component and the substrate.
[0005] In the above clamping fixture, the movable component can move along the first direction. During this process, the first-direction material pushing parts on the movable component will push the materials towards the side wall of the material groove in the first direction, thereby realizing the precise positioning of the materials in the first direction. The fixing mechanism maintains the precise positioning of the materials in the first direction by defining the relative movement between the movable component and the substrate. The present application can simultaneously complete the precise positioning of at least two materials without aligning the materials one by one, which is beneficial to improving the loading efficiency of the materials and thus improving the production efficiency of the materials.
[0006] In some embodiments, the positioning mechanism further includes a rotating connecting piece. The bottom of the rotating connecting piece is fixedly connected to the substrate, and the connecting part of the rotating connecting piece is rotationally connected to the movable component along an axis parallel to a second direction.
[0007] In the clamping fixture of the above embodiment, it is convenient to realize the opening and closing operation of the movable component relative to the substrate, and when the movable component moves away from the substrate, the material groove can be vacated for loading, which is beneficial to improving the loading efficiency of the materials.
[0008] In some embodiments, the connecting portion includes an oval through-hole and a rotating shaft. The bottom of the connecting portion is fixedly arranged on the substrate. The oval through-hole is arranged on the connecting portion, and the major axis direction of the cross-section of the oval through-hole is not perpendicular to the first direction. The rotating shaft is arranged in the oval through-hole and connected to the movable component.
[0009] In the clamping fixture of the above embodiment, when the rotating shaft moves in the oval through-hole, the rotating shaft can drive the movable component to move, so that the feeding portion in the first direction accurately positions the material in the first direction. Moreover, the rotating shaft is beneficial to the rotation of the movable component relative to the substrate.
[0010] In some embodiments, the rotating shaft is elastically connected to the connecting portion to abut the rotating shaft against one side of the oval through-hole along the major axis direction.
[0011] In the clamping fixture of the above embodiment, on the one hand, when the movable component moves, the elastic connection can play an auxiliary role through the acting force provided by the rotating shaft on the movable component, thus facilitating labor saving; on the other hand, after the feeding portion in the first direction accurately positions the material in the first direction, the elastic connection can continuously apply an acting force on the movable component in the first direction, thus facilitating maintaining the accurate positioning of the material in the first direction.
[0012] In some embodiments, the positioning mechanism further includes a second-direction positioning member to limit the movement of the movable component in the second direction when the movable component moves. At least two groups of second-direction feeding portions are provided on the side of the movable component protruding toward the second direction to push the material toward the side wall of the material groove in the second direction when the movable component approaches the substrate.
[0013] In the clamping fixture of the above embodiment, the second-direction positioning member is beneficial to providing a positioning basis for the subsequent accurate positioning of the material in the second direction; through the second-direction feeding portions, the material can be further accurately positioned in the second direction, which is more convenient for improving the accurate positioning of the material in the second direction compared to moving the movable component in the second direction to push the material as a whole.
[0014] In some embodiments, the second-direction feeding portions are elastically connected to the movable component.
[0015] In the clamping fixture of the above embodiment, it is beneficial to reduce the risk of damaging the material due to hard contact between the second-direction feeding portions and the material.
[0016] In some embodiments, at least two groups of material pressing portions are provided on the side of the movable component protruding toward the substrate to press the material toward the substrate when the movable component approaches the substrate.
[0017] In the clamping fixture of the above embodiment, the material pressing portions are beneficial to pressing the material tightly in the material groove, beneficial to improving the stability of the clamping fixture for clamping the material, and beneficial to the accurate positioning of the material in the direction where the movable component protrudes toward the substrate.
[0018] In some embodiments, the pressure-applying part is elastically connected to the movable component.
[0019] In the clamping fixture of the above embodiment, it is beneficial to reduce the risk of damaging the material due to hard contact between the pressure-applying part and the material.
[0020] In some embodiments, a machine table positioning pad block that is detachably connected is provided at the bottom of the substrate.
[0021] In the clamping fixture of the above embodiment, it is beneficial to position the clamping fixture through the machine table positioning pad block, and it is also beneficial to repair and replace the pad block.
[0022] In some embodiments, the fixing mechanism includes a rotary locking part. The rotary locking part is rotatably connected to the substrate, and a locking part and an unlocking part are provided along the rotation direction. When the locking part of the rotary locking part contacts the movable component, the relative movement between the movable component and the substrate is restricted, and when the unlocking part contacts the movable component, the relative movement between the movable component and the substrate is restored.
[0023] In the clamping fixture of the above embodiment, the relative movement state between the movable component and the substrate can be changed through the rotation behavior of the rotary locking part, which is beneficial to improving the operation convenience.
[0024] In this application, a positioning mechanism is provided on the clamping fixture. An active component that is movably connected to the substrate is provided on the positioning mechanism. When the active component moves away from the substrate, a loading area can be vacated for loading. The material grooves on the substrate can achieve preliminary positioning of at least two materials at the same time. The active component in this application can move along the first direction. During this process, the first-direction material pushing part on the active component will push the corresponding material towards the groove wall of the corresponding material groove, so as to achieve precise positioning of the material in the first direction; the fixing mechanism restricts the relative movement between the active component and the substrate, so as to achieve precise positioning of the material in the first direction. This application can complete the precise positioning of at least two materials at the same time without aligning the materials one by one, which is beneficial to improving the loading efficiency of the materials and thus improving the production efficiency of the materials.

To make the present utility model clear, elements irrelevant to the description are omitted from the details of this specification.
[0073] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field 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.
[0074] This application discloses a clamping fixture, including a base plate, a positioning mechanism, and a fixing mechanism. At least two material grooves are provided on the top of the base plate and distributed along a first direction. The positioning mechanism includes a movable component; wherein, the movable component is arranged above the material groove and movably connected to the base plate so that the movable component can move relative to the base plate along the first direction. At least two groups of first-direction material pushing parts are provided on the side of the movable component protruding towards the material groove, so that when the movable component moves, the materials are pushed towards the side wall of the material groove along the first direction. The fixing mechanism defines the relative movement between the movable component and the base plate.
[0075] In the above clamping fixture, the movable component can move along the first direction. During this process, the first-direction material pushing parts on the movable component will push the materials towards the side wall of the material groove along the first direction, thereby realizing the precise positioning of the materials in the first direction. The fixing mechanism maintains the precise positioning of the materials in the first direction by defining the relative movement between the movable component and the base plate. This application can simultaneously complete the precise positioning of at least two materials without aligning the materials one by one, which is beneficial to improving the feeding efficiency of the materials and thus improving the production efficiency of the materials.
[0076] Some embodiments of this application will be described below in conjunction with the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.
[0077] Please refer to Figure 1 and Figure 2 , an embodiment of this application provides a clamping fixture 10, including a base plate 110. A plurality of material grooves 111 distributed along a first direction X are provided on the top of the base plate 110. Each material groove 111 corresponds to a material 20 respectively and is used to accommodate a material 20. In this way, the material grooves 111 can realize the preliminary positioning of the materials 20.
[0078] In this embodiment, the substrate 110 is provided with 12 material grooves 111. Therefore, the 12 material grooves 111 can clamp 12 materials 20, and the specific number of clamped materials 20 can be adjusted according to actual needs. In other embodiments, the substrate 110 may be provided with 3, 4, 5 or more material grooves 111.
[0079] Due to the processing accuracy requirements, the accuracy of the preliminary positioning of the material 20 using the material groove 111 does not meet the production needs, and further precise positioning is required. For this reason, the clamping fixture 10 further includes a positioning mechanism 120. The positioning mechanism 120 and the substrate 110 cooperate to complete the precise positioning of the material 20.
[0080] Please refer to Figure 1 and Figure 2 , the positioning mechanism 120 includes a movable component 121, and the movable component 121 is arranged above the material groove 111. The movable component 121 is movably connected to the substrate 110 so that the movable component 121 can move relative to the substrate 110 along the first direction X. In this embodiment, the movable component 121 is rotatably movably connected to the substrate 110. Of course, in other embodiments, detachable connections such as snap connection and bolt connection can also be used, which will not be elaborated here.
[0081] It is not difficult to understand that in some embodiments, the movable component 121 can move relative to the substrate 110 in the opposite direction of the first direction X.
[0082] Since the movable component 121 is movably connected to the substrate 110, there are at least two states between the movable component 121 and the substrate 110: a separated state in which the movable component 121 is separated from the substrate 110, and a close state in which the movable component 121 is close to the substrate 110. In other words, the movable component 121 can perform an opening and closing operation relative to the substrate 110, which is convenient for loading the material 20 and adjusting the distance between the first-direction material pushing part 1211 and the material 20.
[0083] Please refer to Figure 3, on one side where the movable component 121 protrudes toward the material chute 111, there are 12 groups in total of 24 first-direction material pushing parts 1211. Each group corresponds to one material 20 and includes two first-direction material pushing parts 1211 for precisely positioning the material 20 in the first direction X. When the movable component 121 moves, the two first-direction material pushing parts 1211 push the corresponding material 20 in the first direction X toward the side wall of the material chute 111 corresponding to the material 20. Thus, when the movable component 121 is in the close state close to the substrate 110, the first-direction material pushing parts 1211 can contact the materials 20 in the material chute 111 and push multiple materials 20 toward the side walls of the corresponding material chutes 111 in the first direction X when the movable component 121 moves, which is conducive to realizing the simultaneous precise positioning of multiple materials 20 in the first direction X.
[0084] In this embodiment, the movable component 121 is provided with 12 groups in total of 24 first-direction material pushing parts 1211, and each group of first-direction material pushing parts 1211 corresponds to one material chute 111. In other embodiments, according to actual needs, the movable component 121 can be provided with 2 groups, 3 groups, 4 groups or more groups of first-direction material pushing parts 1211, and each group of first-direction material pushing parts 1211 can also be selected as 1, 2, 3 or more first-direction material pushing parts 1211, which are not limited herein.
[0085] In practical applications, the first-direction material pushing parts 1211 and the movable component 121 can be integral or separate.
[0086] In this embodiment, the 12 groups of first-direction material pushing parts 1211 are arranged in an array on the movable component 121 along the first direction X. Thus, when the first-direction material pushing parts 1211 push the materials 20, it is conducive to improving the consistency of the movement of the materials 20.
[0087] To better illustrate the movement of the aforementioned movable component 121 and the rotational movable connection between the movable component 121 and the substrate 110, the following describes in combination with the relevant components and structures involving rotational movable connection in this embodiment.
[0088] Please refer to Figures 2 to 4 , the positioning mechanism 120 further includes a rotational connecting piece 122. The bottom of the rotational connecting piece 122 is fixedly connected to the substrate 110, and the connecting part 1221 of the rotational connecting piece 122 is rotationally connected to the movable component 121 along an axis parallel to the second direction Y. Thus, it can facilitate the opening and closing operation of the movable component 121 relative to the substrate 110, and when the movable component 121 is away from the substrate 110, the material chute 111 can be vacated for feeding, which is conducive to improving the feeding efficiency of the materials 20.
[0089] In this embodiment, the second direction Y is parallel to the upper surface of the substrate 110 and orthogonal to the first direction X. Of course, in other embodiments, the second direction Y is parallel to the surface of the substrate 110, and there is a non-zero angle between the second direction Y and the first direction X, thereby forming the movable component 121. In other words, the second direction Y is not parallel to the first direction X. In this embodiment, the second direction Y is orthogonal to the first direction X.
[0090] Please refer to Figure 4 , the rotating connecting member 122 includes a connecting portion 1221, an oval through hole 1222, and a rotating shaft 1223. The connecting portion 1221 is fixedly arranged on the substrate 110. The oval through hole 1222 is arranged on the connecting portion 1221, and the major axis direction of the cross-section of the oval through hole 1222 is parallel to the first direction X. The rotating shaft 1223 is arranged in the oval through hole 1222 and connected to the movable component 121. In this way, when the rotating shaft 1223 moves in the oval through hole 1222, the rotating shaft 1223 can drive the movable component 121 to move, so that the first-direction material pushing portion 1211 accurately positions the material 20 in the first direction X. Moreover, it is beneficial for the movable component 121 to rotate relative to the substrate 110 through the rotating shaft 1223.
[0091] In this embodiment, the major axis direction of the cross-section of the oval through hole 1222 is parallel to the first direction X. In this way, the offset of the rotating shaft 1223 relative to the first direction X during the movement in the oval through hole 1222 can be reduced, which is more beneficial for driving the movable component 121 to move through the rotating shaft 1223.
[0092] Of course, in other embodiments, the major axis direction of the cross-section of the oval through hole 1222 only needs to be set not perpendicular to the first direction X, and the oval through hole 1222 provides a moving space for the rotating shaft 1223. Therefore, the movement of the rotating shaft 1223 in the oval through hole 1222 can be decomposed into a movement along the first direction X, so that the movable component 121 can move relative to the substrate 110 along the first direction X.
[0093] In other embodiments, it is also possible to keep the rotation axis of the movable component 121 and the substrate 110 along the second direction Y stationary, and let the movable component 121 slide relative to the rotation axis through a sliding groove (not shown in the figure), so as to realize the movement of the movable component 121 relative to the substrate 110 along the first direction X. The specific structure will not be elaborated here.
[0094] In this embodiment, the rotating shaft 1223 is elastically connected to the connecting portion 1221 to abut the rotating shaft 1223 against one side of the waist-shaped through hole 1222 along the long axis direction of the waist-shaped through hole 1222. In this way, on the one hand, when the movable assembly 121 moves, the elastic connection can assist by the acting force provided by the rotating shaft 1223 on the movable assembly 121, which is beneficial for saving effort. On the other hand, after the first-direction material feeding portion 1211 accurately positions the material 20 in the first direction X, the elastic connection can continuously apply an acting force to the movable assembly 121 along the first direction X, which is beneficial for maintaining the accurate positioning of the material 20 in the first direction X.
[0095] To better illustrate the form of the elastic connection, the following describes an embodiment of the elastic connection in the present application.
[0096] Please refer to Figure 4 , the connecting portion 1221 is sequentially provided with a fixed section 101, an elastic section 102, and an abutting section 103 along the first direction X. Among them, the fixed section 101 is fixed to the connecting portion 1221, one end of the elastic section 102 is connected to the fixed section 101, and the other end is connected to the abutting section 103. The abutting section 103 abuts against the rotating shaft 1223, so that the elastic section 102 applies an acting force to the rotating shaft 1223 along the first direction X through the abutting section 103. In this way, the elastic section 102 indirectly acts on the rotating shaft 1223 elastically through the abutting section 103, which is beneficial for improving the stability of the elastic acting direction when the rotating shaft 1223 is elastically connected to the connecting portion 1221.
[0097] In other embodiments, one end of the elastic section 102 can also be directly connected to the connecting portion 1221, and the other end abuts against the rotating shaft 1223. The specific structure will not be elaborated.
[0098] Please refer to Figure 4 , the connecting portion 1221 is provided with a mounting hole 104, and the fixed section 101, the elastic section 102, and the abutting section 103 are arranged in the mounting hole 104. The mounting hole 104 communicates with the waist-shaped through hole 1222.
[0099] When the rotating shaft 1223 is elastically connected to the connecting portion 1221, the fixed section 101 can be a screw, such as a stop screw, and the stop screw is screwed into the mounting hole 104. The elastic section 102 can be a spring. The abutting section 103 can be a component with a spherical surface, such as a ball, and the ball protrudes partially from the mounting hole 104 along the first direction X. In this way, it is beneficial to improve the stability of the elastic connection between the rotating shaft 1223 and the connecting portion 1221.
[0100] In practical applications, the number of the fixed section 101, the elastic section 102, and the abutting section 103 can be multiple groups. For example, it can be two groups. In this way, it is beneficial to make the elastic force received by the rotating shaft 1223 relatively uniform when the rotating shaft 1223 is elastically connected to the connecting portion 1221.
[0101] In other embodiments, structures such as a spring rod and a spring piece can also be used to achieve the elastic connection between the rotating shaft 1223 and the connecting portion 1221, and the specific structure will not be elaborated here.
[0102] This embodiment also provides a solution for accurately positioning the material 20 in the second direction Y to improve the positioning accuracy of the clamping fixture 10.
[0103] Please refer to Figure 2 and Figure 5 , the positioning mechanism 120 further includes a second-direction positioning member 123 to limit the movement of the movable component 121 in the second direction Y when the movable component 121 moves. In this way, the second-direction positioning member 123 is beneficial to provide a positioning basis for the subsequent accurate positioning of the material 20 in the second direction Y.
[0104] Please refer to Figure 5 , the second-direction positioning member 123 includes a positioning hole 1231 and a positioning post 1232. The positioning hole 1231 is provided on the movable component 121, and the positioning post 1232 is provided on the substrate 110. After the movable component 121 rotates close to the substrate 110, the positioning post 1232 is inserted into the positioning hole 1231. In this way, the positioning hole 1231 and the positioning post 1232 can cooperate to limit the movement of the movable component 121 in the second direction Y, which is beneficial to the accurate positioning of the material 20 in the second direction Y.
[0105] In other embodiments, the positioning hole 1231 can also be provided on the substrate 110. At this time, the positioning post 1232 is provided on the movable component 121, and the specific structure will not be elaborated here.
[0106] In this embodiment, both the positioning hole 1231 and the positioning post 1232 are arranged away from the rotating connecting member 122. In this way, it is beneficial to reduce the influence of the positioning post 1232 on the rotation and movement of the movable component 121. Of course, the installation positions of the positioning hole 1231 and the positioning post 1232 can also be adjusted according to specific needs, which will not be elaborated here.
[0107] Please refer to Figure 4, on the side where the movable component 121 protrudes toward the second direction Y, there are provided a plurality of second-direction material pushing parts 1212, and each second-direction material pushing part 1212 corresponds to a material 20. When the movable component 121 approaches the substrate 110, the material 20 is pushed toward the side wall of the corresponding material groove 111 in the second direction Y. In this way, through the second-direction material pushing parts 1212, a plurality of materials 20 can be accurately positioned simultaneously in the second direction Y. Compared with moving the movable component 121 in the second direction Y to push the materials 20 as a whole, it is beneficial to improve the convenience of further accurate positioning of the materials 20 in the second direction Y.
[0108] In this embodiment, a positioning block is correspondingly provided for each material 20. When the movable component 121 approaches the substrate 110, the second-direction material pushing part 1212 can push the material 20 toward the side wall of the material groove 111 in the second direction Y by contacting the corresponding positioning block.
[0109] In other embodiments, the movable component 121 may be provided with 2, 3, 4 or more second-direction material pushing parts 1212 according to actual needs.
[0110] In practical applications, each material 20 may correspond to a group of at least two second-direction material pushing parts 1212. Each group of second-direction material pushing parts 1212 applies a force to each material 20 separately, which is beneficial to improve the stability of the second-direction material pushing parts 1212 in positioning the materials 20 in the second direction Y.
[0111] In this embodiment, the second-direction material pushing part 1212 is elastically connected to the movable component 121. In this way, it is beneficial to reduce the risk of damaging the material 20 due to hard contact between the second-direction material pushing part 1212 and the material 20.
[0112] The structure in which the aforementioned rotating shaft 1223 is elastically connected to the connecting part 1221 is applicable to the elastic connection between the second-direction material pushing part 1212 and the movable component 121. Please refer to Figure 6, the second-direction material feeding part 1212 is embedded in the movable component 121. The second-direction material feeding part 1212 is sequentially provided with a fixed section 101, an elastic section 102, and an abutting section 103 along the second direction Y. The fixed section 101 is fixed to the movable component 121. One end of the elastic section 102 is connected to the fixed section 101, and the other end is connected to the abutting section 103, so that the elastic section 102 exerts a force on the abutting section 103 along the second direction Y. In other words, the fixed section 101, the elastic section 102, and the abutting section 103 sequentially arranged on the movable component 121 along the second direction Y constitute the second-direction material feeding part 1212. In this way, the elastic section 102 indirectly acts on the material 20 elastically through the abutting section 103. On the one hand, it is beneficial to improve the stability of the direction of the elastic action. On the other hand, it is also beneficial to reduce the damage to the material 20. And when the movement of the movable component 121 along the second direction Y is restricted by the second-direction positioning member 123, the elastic section 102 can continuously exert a force on the material 20 along the second direction Y, which is beneficial to maintaining the accurate positioning of the material 20 in the second direction Y. At the same time, the risk of damaging the material 20 due to the hard contact between the second-direction material feeding part 1212 and the material 20 is reduced.
[0113] When the second-direction material feeding part 1212 is elastically connected to the movable component 121, the fixed section 101 can be a screw, such as a stop screw, and the stop screw is screwed to the movable component 121. The elastic section 102 can be a spring. The abutting section 103 can be a rod-shaped component, such as a pin shaft, and the pin shaft protrudes partially from the movable component 121 along the second direction Y. In this way, it is beneficial to improve the stability of the second-direction material feeding part 1212 arranged on the movable component 121.
[0114] To further improve the positioning accuracy of the clamping fixture 10, this embodiment also provides a solution for accurately positioning the material 20 in the third direction Z. Among them, the third direction Z is perpendicular to the upper surface of the substrate 110.
[0115] Please refer to Figure 7 , the movable component 121 is provided with at least two sets of material pressing parts 1213 protruding towards the substrate 110 direction, so that when the movable component 121 approaches the substrate 110, the material 20 is pressed towards the substrate 110. In this way, it is beneficial to press the material 20 tightly in the material groove 111 through the material pressing parts 1213, which is beneficial to improving the stability of the clamping fixture 10 for clamping the material 20, and is also beneficial to the accurate positioning of the material 20 in the direction where the movable component 121 protrudes towards the substrate 110. In this embodiment, the direction where the movable component 121 protrudes towards the substrate 110 is parallel to the third direction Z.
[0116] In practical applications, each material 20 corresponds to at least two material pressing parts 1213 in a group. In this way, each group of material pressing parts 1213 individually exerts a force on each material 20, which is beneficial to improving the stability of the accurate positioning of the material 20 in the third direction Z, and the specific structure will not be elaborated here.
[0117] In this embodiment, the blank holding part 1213 is elastically connected to the movable component 121. In this way, it is beneficial to reduce the risk of damaging the material 20 due to hard contact between the blank holding part 1213 and the material 20.
[0118] The structure in which the aforementioned rotating shaft 1223 is elastically connected to the connecting part 1221 is applicable to the elastic connection between the blank holding part 1213 and the movable component 121. Please refer to Figure 8 , the blank holding part 1213 is embedded in the movable component 121. The blank holding part 1213 is sequentially provided with a fixed section 101, an elastic section 102, and an abutting section 103 in the direction convex towards the substrate 110. The fixed section 101 is fixed to the movable component 121, and the abutting section 103 cooperates with the fixed section 101 to limit the elastic section 102 inside the fixed section 101, so that the elastic section 102 applies a force to the abutting section 103 in the direction convex towards the substrate 110 of the movable component 121. In other words, the fixed section 101, the elastic section 102, and the abutting section 103 sequentially arranged in the direction convex towards the substrate 110 on the movable component 121 form the blank holding part 1213. In this way, since the elastic section 102 is limited inside the fixed section 101, it is beneficial to reduce the space occupied by the elastic section 102 on the movable component 121, thereby facilitating the arrangement of the blank holding part 1213 on the movable component 121. Moreover, the elastic section 102 can continuously apply a force to the material 20 in the direction convex towards the substrate 110 of the movable component 121, which is beneficial to maintaining the precise positioning of the material 20 in the third direction Z.
[0119] When the blank holding part 1213 is elastically connected to the movable component 121, the blank holding part 1213 can be a spring plunger, and the fixed section 101, the elastic section 102, and the abutting section 103 respectively correspond to the respective parts of the spring plunger.
[0120] In order to maintain the precise positioning of the material 20 at least in the first direction X, this embodiment also provides a solution for locking and fixing the material 20.
[0121] Please refer to Figure 2 and Figure 5 , the clamping fixture 10 includes a fixing mechanism 130, and the fixing mechanism 130 limits the relative movement between the movable component 121 and the substrate 110. In this way, it is beneficial to maintain the precise positioning of the material 20 in the first direction X.
[0122] The fixing mechanism 130 includes a rotary locking member, and the rotary locking member is rotatably connected to the substrate 110.
[0123] Please refer to Figure 5, the rotary locking member is provided with a locking portion 131 and an unlocking portion 132 along the rotation direction. When the locking portion 131 contacts the movable component 121, the rotary locking member restricts the relative movement between the movable component 121 and the substrate 110. When the unlocking portion 132 contacts the movable component 121, the rotary locking member restores the relative movement between the movable component 121 and the substrate 110. In this way, the relative movement state between the movable component 121 and the substrate 110 can be changed through the rotation behavior of the rotary locking member, which is beneficial to improving the operation convenience.
[0124] In this embodiment, the rotation direction of the rotary locking member is parallel to the plane defined by the first direction X and the second direction Y. Compared with the unlocking portion 132, the locking portion 131 is farther from the rotation axis of the rotary locking member. Along the direction outward from the rotation axis of the rotary locking member, the bottom surface of the locking portion 131 gradually inclines towards the substrate 110. In this way, during the process that the locking portion 131 gradually abuts against the movable component 121, it is beneficial for the rotary locking member to gently press the movable component 121 towards the substrate 110.
[0125] For convenient operation, please refer to Figure 5 , the rotary locking member includes an operating portion 133, and the operating portion 133 protrudes away from the substrate 110 for easy gripping.
[0126] Specifically, the rotary locking member can be a knob. The rotary locking member includes a screw and a screw hole, the screw hole is arranged on the substrate 110, and the screw passes through the movable component 121 and is fixed in the screw hole.
[0127] It is not difficult to understand that the fixing mechanism 130 can include a sliding locking member, etc. The sliding locking member is slidably connected to the substrate 110, so that when the sliding locking member approaches the movable component 121, the sliding locking member restricts the relative movement between the movable component 121 and the substrate 110; when the sliding locking member moves away from the movable component 121, the sliding locking member restores the relative movement between the movable component 121 and the substrate 110. That is, the present application does not limit the locking method.
[0128] Please refer to Figure 2 , the clamping fixture 10 further includes a fixture handle 140, and the fixture handle 140 is arranged on the substrate 110. In this way, it is beneficial to lift the entire clamping fixture 10 by grasping the fixture handle 140.
[0129] Please refer to Figures 2 to 5 , the clamping fixture 10 further includes a movable component handle 150, and the movable component handle 150 is arranged on the movable component 121. In this way, it is beneficial to operate the movable component 121 through the movable component handle 150, such as the opening and closing operation of the movable component 121 relative to the substrate 110 and the translational movement of the movable component 121 mentioned above.
[0130] In this embodiment, the handle 150 of the movable component is disposed on the movable component 121 away from the rotating connecting member 122. Thus, when operating the movable component 121 through the handle 150 of the movable component, it is beneficial to play a role in saving effort.
[0131] In production, after the material 20 is accurately positioned, the entire clamping fixture 10 needs to be moved and positioned to the machine table of the next process for processing operations. After the clamping fixture 10 is used for a long time, the parts for positioning may be worn. For this reason, this embodiment also provides a solution to solve the wear problem.
[0132] Please refer to Figure 9 , the clamping fixture 10 includes a machine table positioning pad 113, and the machine table positioning pad 113 is disposed on the substrate 110 away from the material groove 111, and the substrate 110 is provided with a groove 112 for accommodating the machine table positioning pad 113. Thus, it is beneficial to position the clamping fixture 10 through the machine table positioning pad 113. In this embodiment, the machine table positioning pad 113 is used to position the clamping fixture 10 on the machine table of the next process.
[0133] In this embodiment, the machine table positioning pad 113 is detachably connected to the groove 112. Thus, it is beneficial to repair and replace the machine table positioning pad 113. The machine table positioning pad 113 and the groove 112 can be detachably connected by snap connection, bolt connection, etc.
[0134] In practical applications, the number of the machine table positioning pads 113 can be two. Thus, it is beneficial to improve the accuracy of positioning the clamping fixture 10 through the machine table positioning pads 113. It is not difficult to understand that the number of the machine table positioning pads 113 can be more, such as three, four or five, and this embodiment does not limit this.
[0135] In the above-mentioned clamping fixture 10, first, the movable component 121 is rotated to expose the material groove 111, then at least two materials 20 are placed in the material groove 111, and then the movable component 121 is rotated in the reverse direction to cooperate with the material groove 111 to clamp the material 20. At the same time, by moving the movable component 121 along the first direction X, the first-direction material pushing part 1211 pushes the material 20 along the first direction X towards the side wall of the material groove 111 to accurately position the material 20 in the first direction X. At the same time, the second-direction material pushing part 1212 acts on the material 20 to accurately position the material 20 in the second direction Y; the material pressing part 1213 acts on the material 20 to accurately position the material 20 in the third direction Z. Thus, it is beneficial to achieve accurate positioning of the material 20 in three directions. Finally, the relative movement between the movable component 121 and the substrate 110 is restricted by the rotation locking part of the fixing mechanism 130, so as to stably fix the material 20 in the material groove 111. Thus, it is beneficial to improve the feeding efficiency of the material 20.

As long as appropriate changes and variations made to the above embodiments fall within the substantial scope of the present application, they are within the scope disclosed by the present application.
