[0007] in:

[0008] When the guide engagement part is located at the positioning part, the position of the rotating seat is fixed. When the guide part and the guide engagement part form a guide engagement, and the driving member drives the guide engagement part to move along the second direction, the rotating seat can be driven to rotate along the first direction.

[0034] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] Reference Figures 1 to 3 As shown, this utility model provides a positioning carrier, including a rotating base 10 and a driving component 20, wherein:

[0036] The rotating seat 10 can rotate along the first direction D1, which is the direction of rotation about the center line of the rotating seat 10. The rotating seat 10 has a bearing surface 16, which is used to bear the workpiece 100 to be processed. The rotating seat 10 is provided with a positioning part 11 and a guide part 12. The positioning part 11 extends along the second direction D2 and along the axial direction of the rotating seat 10. The guide part 12 extends in a spiral shape. The positioning part 11 is connected to the guide part 12.

[0037] The driving member 20 is provided with a guide engagement part 30. The guide part 12 and the guide engagement part 30 can form a guide engagement. The driving member 20 is used to drive the guide engagement part 30 to move along the second direction D2, which is the gravity direction.

[0038] The rotating seat 10 of this application mounts a workpiece 100 to be processed on its bearing surface 16. The rotating seat 10 drives the workpiece 100 to rotate, thereby performing processing operations on different surfaces of the workpiece 100. In the embodiment provided in this application, when the guide mating part 30 is located at the positioning part 11, the position of the rotating seat 10 is fixed, that is, the position of the workpiece 100 on the rotating seat 10 is fixed, thereby enabling operation on the corresponding surface of the workpiece 100. After the surface is processed, the position of the rotating seat 10 needs to be adjusted to adjust the other surfaces of the workpiece 100 to be processed to the processing position.

[0039] The adjustment method of the rotating seat 10 is that when the guide engagement part 30 and the guide part 12 form a guide engagement, the drive member 20 drives the guide engagement part 30 to move along the second direction D2, which can drive the rotating seat 10 to rotate along the first direction D1.

[0040] Reference Figure 1 As shown, the guide fitting part 30 can initially be located at the upper end of the guide part 12. The driving member 20 drives the guide fitting part 30 to move downward along the second direction D2. The guide fitting part 30 exerts a downward force on the guide part 12. This force can be decomposed into a component force along the first direction D1. As the guide fitting part 30 continues to move downward, the rotating seat 10 is continuously subjected to this component force and moves along the first direction D1, thereby realizing the rotation of the rotating seat 10 along the first direction D1. When the guide fitting part 30 moves to the positioning part 11, it indicates that the rotating seat 10 has moved to a position where the workpiece 100 can be processed.

[0041] In one feasible implementation, refer to Figure 4 as well as Figure 5As shown, the positioning part 11 is a first groove 111 formed by the inward recess of the surface of the rotating seat 10. The first groove 111 extends along the second direction D2, that is, the first groove 111 is a groove set in the vertical direction.

[0042] The guide fitting part 30 can move up and down within the first groove 111. When the guide fitting part 30 is located within the first groove 111, the rotating seat 10 remains in a fixed position.

[0043] Furthermore, the guide portion 12 is a second groove 121 formed by the inward recess of the surface of the rotating seat 10. The second groove 121 is a spiral groove provided on the outer peripheral surface of the rotating seat 10. The second groove 121 communicates with the first groove 111. When the guide fitting portion 30 moves from the first groove 111 into the second groove 121, it can form a guide fit with the second groove 121. Since the second groove 121 is a spiral groove, when the guide fitting portion 30 moves in the second groove 121, the linear motion of the guide fitting portion 30 can be converted into the rotational motion of the rotating seat 10, thereby causing the rotating seat 10 to rotate and change the position of the workpiece 100.

[0044] The first groove 111 includes a first end and a second end. In the second direction D2, the first end of the first groove 111 is located above the second end of the first groove 111. The first end of the first groove 111 is the top end of the first groove 111, and the second end of the first groove 111 is the bottom end of the first groove 111.

[0045] In one feasible embodiment, the depth of the first groove 111 recessed inward from the surface of the rotating seat 10 decreases from the second end of the first groove 111 to the first end of the first groove 111, so that the groove depth of the first groove 111 decreases from bottom to top. The bottom wall of the first groove 111 is inclined, and the depth of the bottom end of the first groove 111 is greater than the depth of the top end of the first groove 111. When the guide fitting part 30 moves in the first groove 111, the inclined bottom wall of the first groove 111 can guide the guide fitting part 30, so that the guide fitting part 30 can move upward along the inclined surface.

[0046] The second groove 121 includes a first end and a second end. The first end of the second groove 121 is located at the upper end of the spiral groove, and the second end of the second groove 121 is located at the lower end of the spiral groove.

[0047] The first groove 111 and the second groove 121 each include multiple ones. The multiple first grooves 111 and the multiple second grooves 121 are arranged alternately and can be arranged in the manner of "first groove 111-second groove 121-first groove 111-second groove 121". The first end of the second groove 121 is connected to the first end of the adjacent first groove 111, and the second end of the second groove 121 is connected to the second end of another adjacent first groove 111. Thus, the multiple first grooves 111 and the multiple second grooves 121 are connected end to end in sequence. The guide fitting part 30 moves in the first groove 111 and the second groove 121 respectively, so as to realize the continuous rotation of the rotating seat 10.

[0048] Specifically, the guide mating part 30 is initially located at the second end of the first groove 111. Under the action of the driving member 20, it moves from the second end of the first groove 111 to the first end of the first groove 111 (that is, the guide mating part 30 moves from bottom to top along the second direction D2). When the guide mating part 30 moves to the first end of the second groove 121, it moves from top to bottom along the second direction D2 under the drive of the driving member 20. During the movement, it applies force to the second groove 121 to drive the rotating seat 10 to rotate along the first direction D1. When the guide mating part 30 moves to the second end of the second groove 121, the rotating seat 10 rotates to the next position of the workpiece 100 that needs to be processed.

[0049] By repeating the above steps, the rotating seat 10 can be continuously rotated, thereby driving the workpiece 100 to rotate synchronously, so as to change the different operating surfaces of the workpiece 100.

[0050] Since the guide engagement part 30 can only move up and down along the second direction D2, when the driving member 20 drives the guide engagement part 30 to move downward along the second direction D2, the guide engagement part 30 may move from the first end of the first groove 111 to the second end of the first groove 111, which will cause the rotating seat 10 to be unable to rotate. Therefore, in the embodiment provided in this application, a first limiting part 17 is provided at the connection between the first end of the second groove 121 and the first end of the adjacent first groove 111. The first limiting part 17 is used to restrict the guide engagement part 30 from moving from the first end of the first groove 111 to the second end of the first groove 111. That is, the first limiting part 17 can prevent the guide engagement part 30 from moving from the top end of the first groove 111 to the bottom end of the first groove 111. When the driving member 20 drives the guide engagement part 30 to move downward along the second direction D2, the guide engagement part 30 can only move within the second groove 121.

[0051] As an example, the depth of the first end of the first groove 111 recessed inward from the surface of the rotating seat 10 is less than the depth of the first end of the second groove 121 recessed inward from the surface of the rotating seat 10. As a result, a step 171 is formed at the connection between the first end of the first groove 111 and the first end of the second groove 121. The step 171 is the first limiting part 17. When the guide fitting part 30 moves from the second end of the first groove 111 to the first end of the first groove 111, it enters the first end of the second groove 121 via the step 171. When the driving member 20 drives the guide fitting part 30 to move downward, the guide fitting part 30 is not easy to move downward from the first groove 111 due to the obstruction of the step 171, so that it moves along the second groove 121.

[0052] Similarly, when the guide fitting part 30 is located at the connection between the second end of the first groove 111 and the second end of the second groove 121, when the driving member 20 drives the guide fitting part 30 to move upward along the second direction D2, it may also move along the second groove 121. Therefore, a second limiting part 181 is provided at the connection between the second end of the second groove 121 and the second end of another adjacent first groove 111. The second limiting part 181 is used to restrict the guide fitting part 30 from moving from the second end of the second groove 121 to the first end of the second groove 121. That is, when the guide fitting part 30 moves along the second groove 121 and drives the rotating seat 10 to rotate a certain angle, under the action of the second limiting part 181, when the driving member 20 drives the guide fitting part 30 to move upward again, the guide fitting part 30 can only move upward within the first groove 111 and cannot move from the second end of the second groove 121 to the first end of the second groove 121.

[0053] As an example, a blocking surface 181 is provided at the first end of the first groove 111. The blocking surface 181 constitutes the second limiting part 18. The blocking surface 181 is located below the connection between the second end of the first groove 111 and the second end of the second groove 121. After the guide fitting part 30 moves to the connection between the second end of the first groove 111 and the second end of the second groove 121, it continues to move downward and can move completely into the first groove 111. Under the action of the blocking surface 181, when the driving member 20 drives the guide fitting part 30 to move upward along the second direction D2 again, the guide fitting part 30 can only move within the first groove 111.

[0054] In other embodiments, the first limiting part 17 and the second limiting part 18 may adopt other structures or components, which are not limited here.

[0055] In the embodiments provided in this application, reference is made to Figure 7 As shown, the guide mating part 30 includes a guide post 31, and the driving member 20 is connected to the guide post 31. When the driving member 20 drives the guide post 31 to move along the second direction D2, the guide post 31 keeps abutting against the positioning part 11 or the guiding part 12 to ensure the stability of the movement of the guide post 31.

[0056] To ensure that the guide post 31 always abuts against the positioning part 11 or the guide part 12 during movement, refer to Figure 8 as well as Figure 9 As shown, the guide mating part 30 also includes an elastic element 32 and a fixed seat 33. The fixed seat 33 is connected to the drive member 20. The two ends of the elastic element 32 are respectively connected to the guide post 31 and the fixed seat 33. When the guide post 31 moves along the second direction D2 in the positioning part 11 or the guide part 12, the elastic element 32 will always be compressed and undergo elastic deformation to accumulate elastic force, and apply the elastic force to the guide post 31, so that the guide post 31 can elastically abut against the positioning part 11 or the guide part 12 during the movement.

[0057] In one feasible embodiment, the elastic element 32 is a spring. One end of the spring is connected to the fixed base 33, and the other end of the spring is connected to the guide post 31. When the guide post 31 moves within the positioning part 11 or the guide part 12, the spring is compressed and undergoes elastic deformation to accumulate elastic force. During the movement of the guide post 31, the spring applies the accumulated elastic force to the guide post 31, so that the guide post 31 always abuts against the positioning part 11 or the guide part 12, thereby enabling continuous and stable movement.

[0058] Specifically, since the positioning part 11 is the first groove 111, the depth of the first groove 111 recessed inward from the surface of the rotating seat 10 decreases from the first end of the first groove 111 to the second end of the first groove 111. Therefore, when the guide post 31 moves from the first end of the first groove 111 to the second end of the first groove 111, as the depth of the first groove 111 gradually decreases, the degree of compression of the spring gradually increases, and the elastic force accumulated during the movement of the guide post 31 gradually increases.

[0059] When the guide post 31 moves from the second end of the first groove 111 to the top of the second groove 121, the guide post 31 abuts against the bottom wall of the second groove 121 under the drive of the elastic force applied by the spring. Since the depth of the second groove 121 is greater than the depth of the second end of the first groove 111, coupled with the pressing action of the spring, the guide post 31 cannot return to the first groove 111, and thus remains in the second groove 121 or moves along the second groove 121.

[0060] In other embodiments, the elastic element 32 may be other structures or components that can apply an elastic force to the guide post 31 so that the guide post 31 can elastically abut against the positioning part 11 or the guide part 12, which is not limited here.

[0061] In other embodiments, the positioning part 11 and the guide part 12 can be rib structures, and the guide mating part 30 can be a groove structure. For example, the guide part 12 can be a rib structure arranged in a spiral, and the guide mating part 30 is a groove structure that matches the rib structure. When the groove structure moves relative to the rib structure, it can generate a force, thereby causing the rotating seat 10 to rotate.

[0062] The positioning carrier of this application can enable multiple workpieces (100) to be processed simultaneously, thereby improving work efficiency. In the embodiments provided in this application, reference is made to... Figure 1 as well as Figure 2 As shown, the rotating seat 10 includes multiple parts, and the driving member 20 is provided with multiple guide mating parts 30. The multiple rotating seats 10 correspond one-to-one with the multiple guide mating parts 30. Each guide mating part 30 cooperates with the corresponding rotating seat 10 to realize the change of position of the workpiece 100. The multiple rotating seats 10 and the multiple guide mating parts 30 together realize the synchronous position change of multiple workpieces 100.

[0063] In one feasible embodiment, the drive member 20 includes a drive cylinder 21, and a plurality of guide mating parts 30 are all connected to the end of the piston rod of the drive cylinder 21. When the drive cylinder 21 is activated, the end of the piston rod of the drive cylinder 21 extends and retracts, thereby driving the plurality of guide mating parts 30 to move along the second direction D2.

[0064] In other embodiments, the driving member 20 may be other structures or components capable of driving the guide mating part 30 to move along the second direction D2, and is not limited here.

[0065] After the workpiece 100 to be processed is placed on the rotating seat 10, in order to ensure the stability of the workpiece 100 during the rotation of the rotating seat 10, the positioning carrier also includes a positioning element 40. The positioning element 40 is used to fix the workpiece 100 on the bearing surface 16 of the rotating seat 10. Through the action of the positioning element 40, the workpiece 100 is firmly fixed on the rotating seat 10. When the rotating seat 10 rotates, the workpiece 100 can rotate synchronously and stably with the rotation of the rotating seat 10, thereby improving the processing efficiency of the workpiece 100.

[0066] Based on the above embodiments, the positioning carrier of this application has the following structure: the piston rod end of the drive cylinder 21 is provided with multiple guide mating parts 30, each guide mating part 30 including a fixed seat 33, an elastic element 32, and a guide post 31. (Refer to...) Figure 6 As shown, the rotating seat 10 includes a rotating seat body 13, a rotating shaft 14, and a rotating bearing 15. The rotating bearing 15 is mounted on the rotating shaft 14, and the rotating seat body 13 is connected to the rotating bearing 15 so that the rotating seat 10 can rotate about the rotating shaft 14 as the center line.

[0067] The rotating seat body 13 has multiple first grooves 111 and multiple second grooves 121. The multiple first grooves 111 and multiple second grooves 121 are distributed sequentially and at intervals on the surface of the rotating seat 10. The bottom end of each first groove 111 is connected to the bottom end of the adjacent second groove 121, and the top end of each first groove 111 is connected to the top end of the adjacent second groove 121. Thus, the multiple first grooves 111 and multiple second grooves 121 are sequentially connected end to end on the rotating seat body 13. The workpiece 100 to be processed is fixed on the bearing surface 16 of the rotating seat 10 by the positioning member 40.

[0068] The process of processing workpiece 100 is as follows: multiple workpieces 100 to be processed are fixed on multiple rotating seats 10 respectively by positioning components 40. The drive cylinder 21 is started, which drives multiple guide posts 31 to move along the second direction D2 in the first groove 111 of the corresponding rotating seat 10. They move from the second end of the first groove 111 to the first end of the first groove 111, and after moving upward to the top of the adjacent second groove 121, the guide post 31 and the second groove 121 form a guiding engagement.

[0069] The drive cylinder 21 drives the guide post 31 to move downward along the second direction D2 to apply force to the rotating seat 10, driving the rotating seat 10 to rotate a certain angle along the first direction D1. When the rotating seat 10 rotates to the appropriate angle, the guide post 31 moves to the bottom end of the second groove 121. The drive cylinder 21 continues to drive the guide post 31 to move downward, so that the guide post 31 enters the second end of the adjacent first groove 111. At this time, the position of the rotating seat 10 is fixed, and the workpiece 100 can be processed.

[0070] After one surface of workpiece 100 is machined, the above steps are repeated to complete the machining of multiple surfaces of workpiece 100, thereby improving operational efficiency and reducing the labor intensity of manual operations.

[0071] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
