The regions illustrated in the figures are merely schematic; their shapes are not intended to represent the actual shapes of the devices illustrated and are not intended to limit the scope of the present application.

[0033] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features of the embodiments may be combined with each other.

[0034] See also Figures 1 to 3 , the present application proposes a locking jig 100 that can limit and fix a workpiece (not shown in the figure), and the locking jig 100 includes a base plate 10, a rotating mechanism 20 and a locking mechanism 30. The base plate 10 is roughly a rectangular plate structure with a certain thickness, which can be used to support the workpiece. A mounting seat 11 is provided on the base plate 10, and the rotating mechanism 20 and the locking mechanism 30 are both provided on the mounting seat 11. When in use, the mounting seat 11 can be moved on the base plate 10 along the first direction X of the base plate 10 so that the mounting seat 11 can be adjusted to a suitable position, so that the mounting seat 11 is more adapted to the size of the workpiece. After adjusting to the appropriate position, the mounting seat 11 can be fixed on the base plate 10.

[0035] like Figures 1 to 3 As shown, the rotation mechanism 20 includes a support base 21, a connecting plate 22, and a cover plate 23. The support base 21 is mounted on the mounting base 11, the connecting plate 22 is rotatably connected to the support base 21, and the cover plate 23 is connected to the end of the connecting plate 22 away from the support base 21. During use, the support base 21 can move on the mounting base 11 along the second direction Y of the base plate 10, and the cover plate 23 can move on the connecting plate 22 along the thickness direction Z of the base plate 10, so that the rotation mechanism 20 can be adjusted to a suitable position to better match the size of the workpiece. After adjustment to the appropriate position, the support base 21 can be fixed to the mounting base 11, and the cover plate 23 can be fixed to the connecting plate 22. The second direction Y and the first direction X of the base plate 10 are mutually perpendicular and both perpendicular to the thickness direction Z of the base plate 10, which is also the height direction of the locking fixture 100. The first direction X can be the length direction of the base plate 10 or the width direction of the base plate 10. The connecting plate 22 is provided with a first magnetic member 40, which can be provided on the surface of the connecting plate 22 facing the bottom plate 10. The first magnetic member 40 can be, but is not limited to, a magnet, and can be one or more.

[0036] like Figures 1 to 3 As shown, the locking mechanism 30 includes a base 31, a handle 32, and a buckle 33. The base 31 is fixed to the surface of the mounting base 11 facing away from the base plate 10. The base 31 can be positioned corresponding to the connecting plate 22 (that is, the orthographic projection of the base 31 along the thickness direction Z of the base plate 10 at least partially overlaps with the orthographic projection of the connecting plate 22 along the thickness direction Z of the base plate 10). The handle 32 is fixed to the surface of the connecting plate 22 facing away from the base plate 10. The buckle 33 is elastically connected to the handle 32 and is rotatably connected to the connecting plate 22. One end of the buckle 33 extends from the connecting plate 22 and has a raised locking portion 330 that can engage with the base 31 to lock the rotating mechanism 20. In the locked state, the rotating mechanism 20 cannot rotate, and the cover plate 23 is pressed against the workpiece to limit and secure it. A second magnetic member 50 is provided on the surface of the base 31 facing the connecting plate 22. The magnetic properties of the second magnetic member 50 are opposite to those of the first magnetic member 40. The second magnetic member 50 may be, but is not limited to, a magnet, and may be one or more. In the locked state, the second magnetic member 50 is at least partially in contact with the first magnetic member 40. Thus, when the cover 23 is pressed against the workpiece, the suction force between the second magnetic member 50 and the first magnetic member 40 ensures that the cover 23 is pressed more tightly against the workpiece, and also enhances the stability of the cover 23, preventing the cover 23 from being disengaged. When the buckle 33 is pressed away from one end of the buckle portion 330, the buckle portion 330 disengages from the base 31, and the rotating mechanism 20 is released from the lock.

[0037] In some embodiments, such as Figures 1 to 3As shown, a first opening 101 is provided on the base plate 10. The first opening 101 may penetrate part of the base plate 10 or the entire base plate 10 along the thickness direction Z. The first opening 101 may be a circular hole, and there may be multiple of them. The mounting base 11 is roughly a rectangular parallelepiped, and is provided with a plurality of first waist-shaped holes 110 (a waist-shaped hole refers to a semicircular arc with symmetrical ends and a long hole parallel to the axis formed in the middle). The number of the first waist-shaped holes 110 is the same as the number of the first openings 101. Each first waist-shaped hole 110 penetrates the mounting base 11 along the thickness direction Z, and the extension direction of each first waist-shaped hole 110 (that is, the direction from the center of one semicircular arc to the center of the other semicircular arc) is parallel to the first direction X of the base plate 10. After the mounting base 11 is positioned on the base plate 10 along the first direction X, the orthographic projection of each first waist-shaped hole 110 on the base plate 10 covers one of the first openings 101. Fasteners (not shown) can be screwed into the first waist-shaped holes 110 and the first openings 101 to secure the mounting base 11 to the base plate 10. Fasteners may be, but are not limited to, screws, pins, etc. By providing the first waist-shaped holes 110 on the mounting base 11, the position of the mounting base 11 on the base plate 10 along the first direction X can be flexibly adjusted, thereby adapting to the assembly requirements of different workpieces.

[0038] In some embodiments, such as Figure 3 As shown, the mounting base 11 is further provided with a second opening 111, which can be located inside the first waist-shaped hole 110. The second opening 111 can penetrate a portion of the mounting base 11 or the entire mounting base 11 along the thickness direction Z. The second opening 111 can be a circular hole, and there can be multiple second openings 111. The support base 21 is provided with multiple second waist-shaped holes 210, the number of which is the same as the number of second openings 111. The extension direction of each second waist-shaped hole 210 (i.e., the direction from the center of one semicircular arc to the center of the other semicircular arc) is parallel to the second direction Y of the base plate 10. After the support base 21 is properly positioned on the mounting base 11 along the second direction Y, the orthographic projection of each second waist-shaped hole 210 on the mounting base 11 covers a second opening 111. Fasteners (not shown) can be screwed into each of the second waist-shaped holes 210 and the second opening 111, thereby securing the support base 21 to the surface of the mounting base 11 facing away from the base plate 10. The fasteners may be, but are not limited to, screws, pins, etc. By providing the second waist-shaped holes 210 on the support base 21, the position of the support base 21 on the mounting base 11 along the second direction Y can be flexibly adjusted, thereby adapting to the assembly requirements of different workpieces.

[0039] In some embodiments, such as Figure 3 and Figure 4As shown, the support base 21 includes a symmetrically arranged first portion 211 and second portion 212, and a third portion 213 connecting the first and second portions 211 and 212. The first portion 211 includes a first plate 2111 and a second plate 2112 connected and substantially perpendicular to each other. The first plate 2111 extends horizontally and aligns with the main surface of the mounting base 11. The second waist-shaped hole 210 may be provided in the first plate 2111. The second plate 2112 extends vertically and is substantially perpendicular to the mounting base 11. The second plate 2112 is provided with a first through-hole 2110. The second portion 212 includes a third plate 2121 and a fourth plate 2122 connected and substantially perpendicular to each other. The third plate 2121 extends horizontally and aligns with the main surface of the mounting base 11. The second waist-shaped hole 210 may be provided in the third plate 2121. The fourth plate 2122 extends vertically and is substantially perpendicular to the mounting base 11. The fourth plate 2122 is provided with a second through-hole 2120. The third portion 213 may be connected between the second plate 2112 and the fourth plate 2122 .

[0040] Furthermore, if Figure 3 and Figure 4 As shown, the third portion 213 of the support seat 21 is provided with a buffer block 214, and the buffer block 214 can protrude from the surface of the third portion 213. Figure 2 and Figure 4 As shown, when the connecting plate 22 rotates to contact the buffer block 214 , the buffer block 214 can be used to support and abut the connecting plate 22 to prevent further rotation.

[0041] In some embodiments, such as Figure 3 As shown, the rotating mechanism 20 further includes rotating components, including a first rotating shaft 201, a washer 202, and a bearing 203. A first through-slot 220 is defined at one end of the connecting plate 22, proximate to the support base 21. The extending direction of the first through-slot 220 is generally parallel to the first direction X of the base plate 10. The first rotating shaft 201 is partially received within the first through-slot 220. The ends of the first rotating shaft 201 extend from the first through-slot 220 and into the first through-hole 2110 and second through-hole 2120 of the support base 21, respectively. The ends of the first rotating shaft 201 are secured to the first through-hole 2110 and second through-hole 2120, respectively, by fasteners 204, which may be, but are not limited to, screws. Washers 202 are mounted on both ends of the first rotating shaft 201, and bearings 203 are mounted on the outer surface of the washers 202, i.e., the washers 202 are positioned between the bearings 203 and the first rotating shaft 201. One bearing 203 is received in the first through hole 2110, and the other bearing 203 is received in the second through hole 2120. By disposing the first rotating shaft 201, the washer 202, and the bearing 203 at one end of the connecting plate 22, the connecting plate 22 and the cover plate 23 can rotate about the first rotating shaft 201. The washer 202 and the bearing 203 can reduce the friction coefficient during rotation.

[0042] In some embodiments, such as Figure 1 and Figure 3 As shown, the connecting plate 22 extends generally along the second direction Y of the base plate 10. One end of the connecting plate 22, which is provided with a first through-slot 220, can be received within the space of the support base 21. The middle portion of the connecting plate 22 can be located on the surface of the base 31, and the first magnetic member 40 can be located in the middle portion facing the surface of the base plate 10. The other end of the connecting plate 22 is connected to the cover plate 23. This end connected to the cover plate 23 is provided with a third opening 221. The cover plate 23 includes a vertical portion 231 and a horizontal portion 232, which are perpendicular to each other. The vertical portion 231 is generally perpendicular to the main plane of the base plate 10 (i.e., the plane formed by the first direction X and the second direction Y). The horizontal portion 232 is generally parallel to the main plane of the base plate 10 and extends generally along the second direction Y. The vertical portion 231 is provided with a third waist-shaped hole 230, which extends parallel to the thickness direction Z of the base plate 10. The number of third waist-shaped holes 230 is the same as the number of third openings 221, and both can be one or more. After the cover plate 23 is properly positioned on the connecting plate 22 along the thickness direction Z, each third waist-shaped hole 230 covers a third opening 221. Fasteners 233 can be screwed into each third waist-shaped hole 230 and each third opening 221, thereby securing the cover plate 23 to the connecting plate 22. Fasteners 233 may be, but are not limited to, screws. Providing the third waist-shaped holes 230 on the cover plate 23 allows for flexible adjustment of the cover plate 23's position on the connecting plate 22 along the thickness direction Z, thereby adapting to the assembly requirements of different workpieces.

[0043] In some embodiments, such as Figure 1 and Figure 3 As shown, the rotating mechanism 20 may further include a protective member 24, which is fixed to the third portion 213 of the support seat 21. The protective member 24 includes a main body 241 and an extension portion 242. The main body 241 is a roughly rectangular plate-like structure, and the main body 241 can be fixed to the third portion 213 by fasteners such as screws and pins. The extension portion 242 can be formed by extending a portion of the surface of the main body 241 along the thickness direction Z and then extending along the second direction Y, and its cross-section is roughly "L"-shaped. The number of extension portions 242 can be two, one of which can fit the partial top surface of the first portion 211 of the support seat 21, and the other extension portion 242 can fit the partial top surface of the second portion 212 of the support seat 21. During the rotation of the connecting plate 22, the two extension portions 242 can limit the connecting plate 22 within a certain range to prevent the connecting plate 22 and other structures from swinging left and right.

[0044] In some embodiments, such as Figure 2 and Figure 3As shown, the base 31 of the locking mechanism 30 can be arranged side by side with the support base 21 along the second direction Y on the surface of the mounting base 11 facing away from the base plate 10. The surface of the base 31 facing away from the support base 21 can be partially recessed inward to form a first groove 310. The first groove 310 is used to engage with the locking portion 330 of the latch 33, thereby locking the rotating mechanism 20. A buffer member 34 can be provided on the base 31. The buffer member 34 can extend from the base 31 at both ends. One end of the buffer member 34 can abut against the connecting plate 22 after extending from the base 31 (abutment means that the two are in contact and have a force acting on each other), and the other end of the buffer member can extend from the base 31 to extend into the third through hole 102 on the base plate 10 (the third through hole 102 extends through the base plate 10 along the thickness direction Z). As the cover plate 23 rotates to contact and press the workpiece, the attractive force between the first magnetic member 40 and the second magnetic member 50 increases the rotational speed of the cover plate 23 and the connecting plate 22, making it more likely that the connecting plate 22 will collide with the base 31. The buffer member 34 reduces the rotational speed, allowing the connecting plate 22 to contact the base 31 more gently, thereby preventing damage caused by impact. The buffer member 34 can be a damper.

[0045] In some embodiments, such as Figure 2 and Figure 3 As shown, a magnetic sensor 35 is also provided on the base 31. One end of the magnetic sensor 35 can be flush with the surface of the base 31 facing away from the bottom plate 10, and the other end can extend from the base 31 and extend to the third through hole 102 of the bottom plate 10. A third magnetic member 60 is also provided on the surface of the connecting plate 22 facing the bottom plate 10. The third magnetic member 60 can be, but is not limited to, a magnet. Figure 1 In the locked state shown, the first magnetic member 40 and the second magnetic member 50 are correspondingly arranged and can fit together; the third magnetic member 60 can be correspondingly arranged with the magnetic sensor 35 and can fit together. The magnetic sensor 35 can be installed in multiple locations on the base 31, and the installation location can be selected according to actual needs. The magnetic sensor 35 can be connected to the control center (not shown). When the magnetic sensor 35 senses the magnetism of the third magnetic member 60, it indicates that the connecting plate 22 and the cover plate 23 are fastened in place, and the control center will issue an instruction to proceed to the next action; otherwise, the next action cannot be performed. In other words, the magnetic sensor 35 can play a role in preventing the system from being fooled.

[0046] In some embodiments, such as Figure 3 As shown, the handle 32 is generally a block-shaped structure, and its surface facing the buckle 33 may be partially recessed inward to form a second groove 320 to accommodate the portion of the buckle 33 away from the engaging portion 330. The locking mechanism 30 may further include an elastic member 36, one end of which is fixed to the bottom wall of the second groove 320 and the other end is fixed to the surface of the buckle 33 facing the handle 32. The elastic member 36 may be, but is not limited to, a spring.

[0047] In some embodiments, such as Figure 3 and Figure 5 As shown, the buckle 33 includes a main body 331, a protruding portion 332 protruding from the main body 331, and a snap-fit ​​portion 330. The protruding portion 332 is located approximately in the middle of the main body 331, and the snap-fit ​​portion 330 is located at the end of the main body 331. The snap-fit ​​portion 330 is generally hook-shaped. The protruding portion 332 is provided with a second through-slot 3320 that passes through the protruding portion 332. The second through-slot 3320 extends approximately parallel to the first through-slot 220 on the connecting plate 22, and both extend along the first direction X of the base plate 10. The connecting plate 22 is also provided with a fourth through-hole 222 that passes through the connecting plate 22 along the thickness direction Z. The protruding portion 332 of the buckle 33 can be located within the fourth through-hole 222, and the snap-fit ​​portion 330 can extend from the fourth through-hole 222. Corresponding to the position of the fourth through hole 222 , the connecting plate 22 is further provided with two fourth openings 223 symmetrically arranged along the first direction X. The two fourth openings 223 are respectively arranged corresponding to the two ends of the second through groove 3320 .

[0048] Furthermore, the locking mechanism 30 may also include a second rotating shaft 37 and a retaining spring 38. The second rotating shaft 37 is partially received in the second through-slot 3320 of the buckle 33, with both ends extending from the second through-slot 3320 and into the fourth opening 223 on the connecting plate 22, and then extending out of the fourth opening 223. The retaining spring 38 can be fitted over the ends of the second rotating shaft 37 extending from the fourth opening 223, thereby securing the second rotating shaft 37. By configuring the second rotating shaft 37 and retaining spring 38, when one end of the buckle 33 is pressed away from the engaging portion 330, the engaging portion 330 tilts upward as the second rotating shaft 37 rotates, thereby releasing the lock.

[0049] The locking jig 100 of the embodiment of the present application is capable of multi-directional adjustment in the horizontal and vertical directions by providing a mounting seat 11 movable along the first direction X, a support seat 21 movable along the second direction Y, and a cover plate 23 movable along the thickness direction Z on the base plate 10. This allows the locking jig 100 to be used to limit and fix workpieces of more different sizes, thereby broadening the scope of use of the locking jig 100. In addition, by providing a first magnetic member 40 on the connecting plate 22 of the rotating mechanism 20 and providing a second magnetic member 50 with different magnetic properties on the base 31 of the locking mechanism 30, the suction force between the second magnetic member 50 and the first magnetic member 40 allows the cover plate 23 to be pressed more tightly against the workpiece, and can also improve the stability of the cover plate 23 and prevent the cover plate 23 from being disengaged. The locking jig 100 of the embodiment of the present application has a simple structure and is easy to operate. It can be used as a standard module, thereby reducing equipment costs.

[0050] The above description is some specific implementation methods of the present application, but in actual application, it is not limited to these implementation methods. For ordinary technicians in this field, other variations and changes made according to the technical concept of the present application should fall within the scope of protection of the present application.
