The linkage 22 slides in the third direction C.

The positioning fixture 100 comprises a substrate 10 and a limiting mechanism 20, wherein a material is carried on the substrate 10, the limiting mechanism 20 is connected with the substrate 10, and the limiting mechanism 20 clamps the material carried on the substrate 10 so as to position the material on the substrate 10. Materials include a variety of types such as electronic product accessories, medical equipment, industrial parts, and the like. The positioning jig 100 further includes a base 40, and the substrate 10 is fixed on the base 40. The base 40 includes a bottom plate 41 and a connection post 42, the connection post 42 is disposed between the bottom plate 41 and the substrate 10, and the bottom plate 41 is connected to the substrate 10 through the connection post 42.

Referring to fig. 4 in combination, the substrate 10 has a top side 10a and a bottom side 10b disposed opposite to each other, and the top side 10a and the bottom side 10b are spaced apart along the Z-axis. The material is carried on the top side 10a, the bottom side 10b is a plane, the upper ends of the connecting columns 42 are connected with the bottom side 10b, and the lower ends of the connecting columns 42 are connected with the bottom plate 41. The stopper mechanism 20 is connected to the bottom side 10b. Alternatively, the shape of the substrate 10 is substantially rectangular.

Optionally, in some embodiments, the substrate 10 includes a placement portion 11 located on the top side 10a and protruding upwards, the material is carried on the placement portion 11, and the material is partially hollowed out towards one side of the placement portion 11, so as to reduce the contact area between the placement portion 11 and the material, thereby reducing the friction between the material and the placement portion 11, and enabling the material to be pushed to move more easily when the limiting mechanism 20 clamps the material.

The limiting mechanism 20 comprises a driving piece 21, two oppositely arranged linkage pieces 22 and two oppositely arranged limiting assemblies 23. The driving member 21 is provided at the bottom side 10b. The two linkage members 22 are located at the bottom side 10b and are respectively connected with the driving member 21, and the driving member 21 drives the two linkage members 22 to reversely and synchronously move along the length direction of the substrate 10. The two limiting assemblies 23 slide relative to the base plate 10 along a direction parallel to the plane where the bottom side 10b is located, and an included angle between the sliding direction of the limiting assemblies 23 and the length direction of the base plate 10 is greater than 0 ° and less than 90 °. Each limiting component 23 is connected with the corresponding linkage piece 22, so that the linkage piece 22 drives the limiting component 23 to slide relative to the substrate 10. The material loaded on the placing part 11 is located between the two limiting assemblies 23, the two limiting assemblies 23 are in contact with corners R of the material, and force is applied to enable the two limiting assemblies 23 to clamp and position the material loaded on the placing part 11. The driving member 21 drives the two linkage members 22 to move synchronously in opposite directions, and alternatively, the driving member 21 is a bidirectional cylinder. It will be appreciated that the driving member 21 is not limited to a bidirectional cylinder, but may be other driving members, for example, the driving member 21 may be a structure comprising a gear and two racks, wherein the two racks are disposed opposite to each other and meshed with the gear respectively, and the racks are connected with the linkage member 22 and are driven to move in opposite directions by rotation of the gear.

When the driving piece 21 drives the two linkage pieces 22 to synchronously move towards opposite directions, the limiting assemblies 23 move along with the linkage pieces 22 so as to drive the two limiting assemblies 23 to synchronously move, and the moving distances of the two limiting assemblies 23 are equal, so that the materials can be accurately clamped and positioned, and the position accuracy of the materials is improved. The included angle between the moving direction of the limiting component 23 and the length direction of the substrate 10 is larger than 0 degrees and smaller than 90 degrees, the driving piece 21, the linkage piece 22 and the limiting component 23 are arranged more tightly, the occupied space is reduced, or when the limiting component 23 loosens materials in the same occupied space, the spacing distance between the limiting component 23 and the materials is larger, and the condition that the limiting component 23 scratches the materials is reduced.

Each limiting assembly 23 comprises a first limiting member 231 and a second limiting member 232, and the first limiting member 231 and the second limiting member 232 are arranged opposite to each other and are respectively connected with the same linkage member 22. The first stopper 231 moves in the first direction a relative to the substrate 10, and the second stopper 232 moves in the second direction B relative to the substrate 10. The driving member 21 drives the linkage member 22 to move in the third direction C with respect to the substrate 10. The first direction a forms a first angle α with the longitudinal direction of the substrate 10, the second direction B forms a second angle β with the longitudinal direction of the substrate 10, and the first angle α is equal to the second angle β. The third direction C is parallel to the longitudinal direction of the substrate 10. When the linkage member 22 moves along the third direction C, the first limiting member 231 is driven to move along the first direction a and the second limiting member 232 is driven to move along the second direction B, and the first limiting member 231 and the second limiting member 232 exert the same force on the material, so as to stably clamp the material carried on the placing portion 11.

Optionally, the first limiting member 231 and the second limiting member 232 have the same structure and are symmetrically disposed along the length direction of the substrate 10.

Optionally, the angles of the first included angle α and the second included angle β are both 45 °, so that the distances of the first limiting member 231 and the second limiting member 232 moving along the length direction of the substrate 10 and along the width direction of the substrate are equal, so that the first limiting member 231 contacts and applies equal pressure to two adjacent sides of the material, so that the stress of the material is balanced, and the position accuracy of the material is convenient to maintain.

Alternatively, in other embodiments, the stop assembly 23 may include only the first stop 231 or only the second stop 232, with material being held by two opposing first stops 231 or second stops 232.

The first limiting piece 231 moves along the first direction a, the second limiting piece 232 moves along the second direction B, and the linkage piece 22 moves along the third direction C, so that the first limiting piece 231 and the second limiting piece 232 clamp and position materials from different directions under the condition that a plurality of driving pieces 21 are not needed, and the positioning accuracy of the materials is improved.

Referring to fig. 3, 4, 5 and 6, optionally, in some embodiments, the material includes a first workpiece 201, two first limiting members 231 abut two corners R on a diagonal of the first workpiece 201, and each first limiting member 231 contacts two sides L of the abutted corner R. The two second stoppers 232 are abutted against the other two corners R of the first workpiece 201 or the workpiece 202, and each second stopper 232 is in contact with the two sides L of the abutted corner R, thereby stably defining the position of the first workpiece 201.

Optionally, in some embodiments, the first stop 231 and the second stop 232 are each generally L-shaped and have a curved surface that is adapted to the corner R of the first workpiece 201, so as to clamp the corner R of the first workpiece 201. The first limiting member 231 and the second limiting member 232 are made of soft materials, so as to reduce the occurrence of scratching materials.

Referring to fig. 7 and 8, in an alternative embodiment, the limiting mechanism 20 further includes a first guiding member 24 and a second guiding member 25, where the first guiding member 24 and the second guiding member 25 are symmetrically disposed on the bottom side 10b along a direction parallel to the length direction of the substrate 10. The number of the first guide pieces 24 and the second guide pieces 25 is two, and each first guide piece 24 corresponds to one first stopper 231, and each second guide piece 25 corresponds to one second stopper 232. The first guide 24 extends in a first direction a and the second guide 25 extends in a second direction B. The first stopper 231 is slidably disposed on the first guide 24 along the first direction a, and the second stopper 232 is slidably disposed on the second guide 25 along the second direction B. When the linkage member 22 drives the first limiting member 231 and the second limiting member 232 to move, the first guiding member 24 and the second guiding member 25 correspondingly guide the first limiting member 231 and the second limiting member 232, so that the first limiting member 231 moves along the first direction a, and the second limiting member 232 moves along the second direction B, thereby stably clamping and positioning the material.

It is understood that the manner in which the first stopper 231 moves in the first direction a and the second stopper 232 moves in the second direction B is not limited to the arrangement of the first guide 24 and the second guide 25, but may be other. For example, the first limiting member 231 and the second limiting member 232 are slidably connected to the substrate 10, so that the first limiting member 231 moves along the first direction a, and the second limiting member 232 moves along the second direction B. For example, only one guide is provided, and the first stopper 231 and the second stopper 232 are slidably connected to the guide.

Optionally, in some embodiments, the first guide 24 is provided with a first guide groove 241 penetrating through the upper and lower sides of the first guide 24, and a length direction of the first guide groove 241 is parallel to the first direction a. The first stopper 231 has a first sliding portion 2311 at a lower end thereof, and the first sliding portion 2311 is slidably disposed in the first guide groove 241 along the first direction a. The second guide 25 is provided with a second guide groove 251 penetrating through the upper and lower sides of the first guide 24, the length direction of the second guide groove 251 is parallel to the second direction B, and the first guide groove 241 and the second guide groove 251 are symmetrically arranged. The second limiting member 232 has a second sliding portion 2321 at a lower end thereof, the second sliding portion 2321 is symmetrically disposed with the first sliding portion 2311, and the second sliding portion 2321 is slidably disposed in the second guiding groove 251 along the second direction B.

It is to be understood that the sliding fit of the first guide 24 and the first limiting member 231, the sliding fit of the second guide 25 and the second limiting member 232 is not limited thereto, and other manners, such as the first guide 24 being provided with the first sliding portion 2311, the first limiting member 231 being provided with the first guiding slot 241, the second guide 25 being provided with the second sliding portion 2321, and the second limiting member 232 being provided with the second guiding slot 251, may be adopted.

The linkage 22 contacts the first sliding portion 2311 and the second sliding portion 2321, so that when the linkage 22 moves, the first sliding portion 2311 and the second sliding portion 2321 are driven to move the first limiting member 231 and the second limiting member 232.

The linkage member 22 includes a connection portion 221, a first push-pull portion 222 and a second push-pull portion 223 both located at the bottom side 10b, the connection portion 221 is connected with the driving member 21, and the first push-pull portion 222 and the second push-pull portion 223 are disposed at intervals and are connected with one side of the connection portion 221 away from the driving member 21. The first push-pull portion 222 contacts the first sliding portion 2311 of the first limiting member 231, and the second push-pull portion 223 contacts the second sliding portion 2321 of the second limiting member 232, so that when the driving member 21 drives the two linkage members 22 to move away from each other along the third direction C, the first push-pull portion 222 pushes the first sliding portion 2311 to move along the first direction a, and the second push-pull portion 223 pushes the second sliding portion 2321 to move along the second direction B. The two first limiting members 231 and the two second limiting members 232 are far away from each other, and at this time, the limiting mechanism 20 is in a released state, so that the first workpiece 201 is carried on the substrate 10. When the driving member 21 drives the two linkage members 22 to move closer together along the third direction C, the first push-pull portion 222 pulls the first sliding portion 2311 to move along the first direction a, and the second push-pull portion 223 pulls the second sliding portion 2321 to move along the second direction B, so that the two first limiting members 231 and the two second limiting members 232 move closer together to clamp the material, and the limiting mechanism 20 is in a clamped state.

In some embodiments, the first push-pull portion 222 includes a first push block 2221 and a first pull block 2222, where the first push block 2221 and the first pull block 2222 are disposed at intervals, and a gap is formed between the first push block 2221 and the first pull block 2222, so that the lower end of the first sliding portion 2311 passes through the first guide slot 241 and extends into the gap between the first push block 2221 and the first pull block 2222. The second push-pull portion 223 includes a second push block 2231 and a second pull block 2232, where the second push block 2231 and the second pull block 2232 are disposed at intervals, and a gap is formed between the second push block 2231 and the second pull block 2232 so that a lower end of the second sliding portion 2321 passes through the second guide groove 251 and extends into the gap between the second push block 2231 and the second pull block 2232.

When the two link members 22 move in the mutually away direction, the first pushing block 2221 contacts with the corresponding first sliding portion 2311, so as to push the first sliding portion 2311 to move along the first direction a, and the second pushing block 2231 contacts with the corresponding second sliding portion 2321, so as to push the second sliding portion 2321 to move along the second direction B, and the two first limiting members 231 and the two second limiting members 232 are mutually away, so that the limiting mechanism 20 is in a released state. When the two linkage members 22 move in the directions approaching each other, the first pull block 2222 pulls the corresponding first sliding portion 2311 to move toward the driving member 21 along the first direction a, and the second pull block 2232 pulls the corresponding second sliding portion 2321 to move toward the driving member 21 along the second direction B, so that the first limiting member 231 and the second limiting member 232 approach each other to bring the limiting mechanism 20 into a clamped state.

It is to be understood that the manner in which the first push-pull portion 222 is engaged with the first sliding portion 2311, and the manner in which the second push-pull portion 223 is engaged with the second sliding portion 2321 is not limited to the manner in which the first push-pull block 2221, the first pull-block 2222, the second push-pull block 2231 and the second pull-block 2232 are passed, and other manners are also possible, for example, the first push-pull portion 222 and the second push-pull portion 223 are provided with grooves, and portions of the first sliding portion 2311 and portions of the second sliding portion 2321 extend into the corresponding grooves.

When the limiting mechanism 20 is in the released state, the pushing portion 224 contacts the stop portion 12 to block the pushing portion 224 from moving along with the linkage member 22 in a direction away from the driving member 21, so as to limit the sliding distance of the pushing portion 224. By the contact of the pushing portion 224 with the stop portion 12, the situation that the moving distance of the linkage member 22 in the direction away from the driving member 21 is too large is reduced, the first sliding portion 2311 collides with the first guiding member 24, and the second sliding portion 2321 collides with the second guiding member 25, resulting in damage to the components occurs.

When the driving member 21 drives the linkage member 22 to move along the third direction C, the first limiting member 231 and the second limiting member 232 are driven to move, so that the two first limiting members 231 and the two second limiting members 232 cooperate to clamp and position the first workpiece 201.

The lifting member 33 is connected to the supporting member 32, and is used for driving the supporting member 32 to move towards the substrate 10, so that an end of the positioning member 31 away from the supporting member 32 can pass through the through hole 13 to extend out of the substrate 10. When the supporting member 32 moves away from the substrate 10, the positioning member 31 is driven to move, so that the positioning member 31 is retracted to release the positioning of the material.

The distance between the first contact surface 3321 and the rotation axis of the rotation part 332 is greater than the distance between the second contact surface 3322 and the rotation axis of the rotation part 332, and when the second contact surface 3322 gradually transits from the contact of the second contact surface 3322 with the support member 32 to the contact of the first contact surface 3321 with the support member 32 during the rotation of the rotation part 332, the rotation part 332 gradually lifts the support member 32 so that a part of the positioning member 31 extends out of the through hole 13. Alternatively, the first contact surface 3321 and the second contact surface 3322 are two surfaces perpendicular to each other, and it is understood that in other embodiments, the first contact surface 3321 and the second contact surface 3322 may be curved surfaces that meet.
