[0004] This application provides a fixture. The fixture includes a fixed plate and a movable component. The fixed plate includes a plate body with a first abutment portion. The movable component is located on the side of the plate body with the first abutment portion and is movably connected to the fixed plate. The movable component includes a pulling member and a positioning member. The positioning member is spaced apart from the first abutment portion and forms an accommodating space for accommodating a workpiece. The pulling member is connected to the positioning member to drive the positioning member to move.

[0006] Optionally, the positioning member has a first part on the side of the guide member away from the first abutment portion, and the positioning member has a second part on the side of the guide member close to the first abutment portion. The first part is provided with one of an engaging part or an engaging groove, and the pulling member is provided with the other of an engaging part or an engaging groove. The engaging part and the engaging groove cooperate to enable the positioning member to move with the pulling member.

[0007] Optionally, the second part has a positioning end face on the side facing the first abutment. The positioning end face extends obliquely away from the first abutment in the direction close to the plate body. A positioning post also extends from the positioning end face toward the first abutment. The positioning post and the positioning end face cooperate to position the end of the workpiece away from the first abutment.

[0008] Optionally, the fixture also includes an elastic element, one end of which engages with a positioning element and the other end of which engages with a fixing plate. The elastic element is used to provide elastic force to the positioning element toward the first abutment portion.

[0009] Optionally, at least two positioning elements are provided, and the at least two positioning elements are respectively connected to the same pulling element. Each positioning element is provided with an elastic element, and the guide element is provided with multiple guide holes. The at least two elastic elements are respectively provided with at least two guide holes.

[0010] Optionally, the plate body is further provided with a second abutting part, which is spaced apart from the first abutting part. An elastic member, a positioning member, and a guide member are located between the second abutting part and the first abutting part. There is an installation space between the guide member and the second abutting part. The elastic member and at least part of the positioning member are located in the installation space.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] Combination Figures 1 to 5 This application provides a fixture. The fixture includes a fixed plate 10 and a movable component. The movable component is movably connected to the fixed plate 10. The movable component can be slidably connected and / or rotatably connected to the fixed plate 10, which is not specifically limited here. Specifically, the fixed plate 10 includes a plate body 11 and a first abutment portion 12, the first abutment portion 12 being disposed on the plate body 11. The movable component is disposed on the side of the plate body 11 having the first abutment portion 12.

[0023] Furthermore, the movable component includes a pulling member 40 and a positioning member 30. The positioning member 30 is spaced apart from the first abutment portion 12 and forms an accommodating space for accommodating the workpiece 2. The workpiece 2 can be clamped in the accommodating space by the positioning member 30 and the first abutment portion 12. The pulling member 40 is connected to the positioning member 30 to drive the positioning member 30 to move. The positioning member 30 engages with the first abutment portion 12 through movement to position the workpiece 2.

[0024] Specifically, the pulling member 40 can pull the positioning member 30 to move, thereby changing the distance between the first abutment portion 12 and the positioning member 30. By increasing the distance between the first abutment portion 12 and the positioning member 30, the workpiece 2 can be conveniently placed between the first abutment portion 12 and the positioning member 30. By shortening the distance between the first abutment portion 12 and the positioning member 30, the workpiece 2 placed between them can be clamped, thereby positioning the workpiece 2. The first abutment portion 12 can abut against one end of the workpiece 2, while the positioning member 30 can abut against the other end of the workpiece 2 through movement. By abutting both ends of the workpiece 2, the workpiece 2 can be positioned. The above method facilitates improving the assembly accuracy when the workpiece 2 is further assembled.

[0025] During the process of the pulling member 40 pulling the positioning member 30, the positioning member 30 may experience unnecessary displacement. To improve this technical problem, in some embodiments, the fixture further includes a guide member 20, which is mounted on the side of the plate 11 with the first abutment portion 12. The guide member 20 is provided with a guide hole, the extension direction of which is the same as the spacing direction between the first abutment portion 12 and the positioning member 30, and the positioning member 30 passes through the guide hole. The guide member 20 is provided with a guide hole, and the positioning member 30 is slidably disposed in the guide hole. During the process of the pulling member 40 pulling the positioning member 30, the guide member 20 can limit the displacement of the positioning member 30 in other directions (except the sliding direction), thereby facilitating accurate contact between the positioning member 30 and the workpiece 2 during the sliding process.

[0026] Combination Figure 4 and Figure 5 In some embodiments, the positioning member 30 has a first portion 31 on the side of the guide member 20 away from the first abutment portion 12, and a second portion 32 on the side of the guide member 20 near the first abutment portion 12. The first portion 31 of the positioning member 30 can be used to connect with the pulling member 40, while the second portion 32 of the positioning member 30 can be used to abut against the workpiece 2. By providing the first portion 31 and the second portion 32 of the positioning member 30 on both sides of the guide member 20, the possibility of the positioning member 30 dislodging from the guide member 20 can be reduced. The first portion 31 is provided with either an engaging portion 311 or an engaging groove 41, and the pulling member 40 is provided with the other engaging portion 311 or an engaging groove 41. The engaging portion 311 cooperates with the engaging groove 41 so that the positioning member 30 can move with the pulling member 40. By using the cooperation of the engaging portion 311 and the engaging groove 41, the installation of the pulling member 40 and the positioning member 30 can be simplified. For example, when multiple positioning elements 30 are provided, each positioning element 30 has a locking portion 311. The positioning element 30 can be pre-installed on the guide element 20, and under the limiting action of the guide element 20, the positioning element 30 already has a suitable spacing. The pulling element 40 can then be directly connected to the positioning element 30 through the engagement of the locking portion 311 and the engagement groove 41.

[0027] Combination Figure 6 In some embodiments, the second portion 32 has a positioning end face 321 on the side facing the first abutment portion 12. The positioning end face 321 extends obliquely away from the first abutment portion 12 in the direction close to the plate body 11. The positioning end face 321 is set as an inclined surface, which allows the positioning end face 321 to restrict the movement of the workpiece 2 away from the plate body 11 after the positioning member 30 abuts against the workpiece 2. The positioning end face 321 can also be a plane, thus further restricting the rotation of the workpiece 2. In this way, the ability of the positioning member 30 to restrict the movement of the workpiece 2 can be increased, which is beneficial for further increasing assembly accuracy.

[0028] Furthermore, a positioning post 322 extends from the self-positioning end face 321 toward the first abutment portion 12. The positioning post 322 can be movably inserted into the workpiece 2. The positioning post 322 can restrict the movement of the workpiece 2 on the axis perpendicular to the positioning post 322, thereby increasing the ability of the positioning member 30 to restrict the movement of the workpiece 2, which is beneficial to further increasing the assembly accuracy.

[0029] In summary, the positioning pin 322 and the positioning end face 321 cooperate to position the end of the workpiece 2 away from the first abutment portion 12. The cooperation between the positioning end face 321 and the first abutment portion 12 restricts the rotational degree of freedom of the workpiece 2, and also restricts the movement degree of freedom of the workpiece 2 in the direction between the first abutment portion 12 and the positioning member 30. Furthermore, by providing the positioning end face 321 and the positioning pin 322, the degree of freedom of the workpiece 2 can be further restricted. By restricting multiple degrees of freedom of the workpiece 2, positioning of the workpiece 2 can be achieved, which helps to increase assembly accuracy.

[0030] Combination Figure 5 In some embodiments, the fixture further includes an elastic element 50, one end of which engages with the positioning element 30, and the other end of which engages with the fixing plate 10. The elastic element 50 provides a spring force to the positioning element 30 toward the first abutment portion 12. The elastic element 50 engages with the fixing plate 10 at multiple locations. For example, if the elastic element 50 is a spring, it can engage with the fixing plate 10 on the side of the guide 20 away from the first abutment portion 12. In this case, the spring length is less than its original length, allowing the spring to provide the aforementioned spring force through extension. Alternatively, the elastic element 50 can engage with the fixing plate 10 on the side of the guide 20 closer to the first abutment portion 12. In this case, the spring length is greater than its original length, allowing the spring to provide the aforementioned spring force through contraction. By providing the elastic element 50, the positioning element 30 can be made to tend to move toward the first abutment portion 12, thereby enabling the positioning element 30 and the first abutment portion 12 to generate a clamping force on the workpiece 2 without the action of external force, thus achieving the positioning of the workpiece 2. Specifically, when workpiece 2 needs to be placed, the user can manually or automatically operate the pulling member 40 to overcome the elastic force generated by the elastic member 50, thereby increasing the distance between the positioning member 30 and the first abutment part 12, facilitating the placement of workpiece 2. After workpiece 2 is placed, the user can release the pulling member 40 or apply a pulling force less than the elastic force, allowing the elastic member 50 to push the positioning member 30 towards workpiece 2, thereby clamping workpiece 2. After the positioning member 30 and the first abutment part 12 cooperate to clamp workpiece 2, the elastic member 50 can continuously generate elastic force, which, in conjunction with the reaction force generated by the first abutment part 12, securely positions workpiece 2.

[0031] In some embodiments, at least two positioning members 30 are provided, and each of the at least two positioning members 30 is connected to the same pulling member 40. Each positioning member 30 is provided with an elastic member 50, and the guide member 20 is provided with multiple guide holes, through which the at least two elastic members 50 pass. By providing multiple positioning members 30, they can cooperate with the first abutment part 12 to form multiple positions for positioning workpieces 2, thereby enabling a single fixture to simultaneously position multiple workpieces 2. Each positioning member 30 is provided with an elastic member 50, ensuring that the process of each positioning member 30 clamping the workpiece 2 with the first abutment part 12 is independent, reducing mutual interference during the positioning processes of different workpieces 2. Since multiple positioning members 30 are simultaneously connected to the same pulling member 40, the total pulling force required for the pulling member 40 during manual or automatic operation by the user is the sum of the elastic forces of the elastic members 50. Thus, by setting an appropriate number of positioning members 30, the pulling force of the pulling member 40 can be kept within a suitable range without affecting the positioning of the workpiece 2 by the elastic members 50, facilitating operation.

[0032] In some embodiments, the plate 11 is further provided with a second abutment portion 13, which is spaced apart from the first abutment portion 12. An elastic member 50, a positioning member 30, and a guide member 20 are located between the second abutment portion 13 and the first abutment portion 12. An installation space exists between the guide member 20 and the second abutment portion 13. The elastic member 50 and at least a portion of the positioning member 30 are located within the installation space. A pulling member 40 covers at least a portion of the installation space away from the opening of the plate 11. The second abutment portion 13 allows the elastic member 50 to abut against it, thereby providing elasticity and enabling the positioning member 30 to tend to move towards the workpiece 2. By providing the pulling member 40 to cover the installation space, the elastic member 50 can be placed in a relatively enclosed space, reducing external interference during the movement of the elastic member 50, or external interference with the operation of the elastic member 50.

[0033] Combination Figures 3 to 5 In some embodiments, the fixed plate 10 is further provided with a limiting part 14, which is located between the first abutment part 12 and the movable component. The limiting part 14 is provided with a limiting groove 141 for accommodating the workpiece 2, and the limiting groove 141 extends through the limiting part 14 along the interval direction between the first abutment part 12 and the positioning member 30. By providing the limiting groove 141, the degree of freedom of the workpiece 2 in the direction perpendicular to the extension of the limiting groove 141 can be further restricted. Furthermore, by providing the limiting groove 141, the placement of the workpiece 2 can be pre-positioned when the pulling member 40 moves the positioning member 30 away from the first abutment part 12, so that the position of the workpiece 2 is directly opposite the first abutment part 12 and the positioning member 30, thereby facilitating the positioning of the positioning end face 321 and the insertion of the positioning post 322 when the positioning member 30 moves toward the workpiece 2.

[0034] In some embodiments, the limiting part 14 is further provided with a relief groove 142, which communicates with the limiting groove 141. Multiple relief grooves 142 are provided, and at least one relief groove 142 is provided on each side of each limiting groove 141. By providing the relief grooves 142, spaces for the grippers to accommodate the workpiece 2 can be formed on both sides of the workpiece 2 placement position, thereby facilitating the gripping and placement of the workpiece 2. Optionally, the relief grooves 142 are arranged along the same straight line, so that the forming of the relief grooves 142 can be completed in one step by a milling machine, reducing the machining difficulty.

[0035] In some embodiments, a positioning groove 121 is provided on the side of the first abutment portion 12 facing the positioning member 30, and the positioning groove 121 is used to accommodate one end of the workpiece 2. By providing the positioning groove 121, the side of the workpiece 2 close to the first abutment portion 12 can be pre-positioned, which facilitates the positioning of the workpiece 2 by the positioning member 30.

[0036] The above are merely embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
