Description

Technical Field

[0001] The utility model relates to the technical field of positioning jigs, and particularly refers to a positioning jig for a hydraulic plate. Background Art

[0002] A hydraulic plate is a commonly used component in the field of hydraulics. It has a complete hydraulic oil circuit inside. Therefore, before its application, the hydraulic plate needs to be processed. In order to ensure the processing accuracy, a positioning device is required to position it.

[0003] The conventional positioning device is to clamp and fix the hydraulic plate on both sides through two clamping cylinders or oil cylinders. However, each hydraulic plate requires two clamping power components, which will result in relatively high costs and energy consumption of the positioning device, and batch positioning cannot be achieved. Summary of the Invention

[0004] The utility model is made in consideration of the foregoing problems. The purpose of the utility model is to provide a positioning jig for a hydraulic plate, which can reduce the number of required clamping power components and can clamp and position multiple hydraulic plates simultaneously.

[0005] To achieve the above purpose, the utility model provides a positioning jig for a hydraulic plate, including a positioning mechanism and a clamping mechanism. The positioning mechanism includes a driving turntable, a driven turntable, and a positioning base plate located between the driving turntable and the driven turntable. The distance between the driving turntable and the driven turntable is adjustable;

[0006] The clamping mechanism includes a fixed clamping plate, a movable clamping plate, and a driving member. The two fixed clamping plates are respectively fixed at both ends of the positioning base plate and are respectively connected to the driving turntable and the driven turntable. A plurality of movable clamping plates are arranged at intervals between the two fixed clamping plates. The driving member can drive any two adjacent movable clamping plates to move in opposite directions, so that the movable clamping plate close to the fixed clamping plate cooperates with the fixed clamping plate to clamp the hydraulic plate or the two adjacent movable clamping plates approaching each other cooperate to clamp the hydraulic plate.

[0007] For the positioning jig for a hydraulic plate as described above, the driving member includes a driving seat, which is located between two adjacent movable clamping plates and can move toward one side close to or away from the positioning base plate;

[0008] A first inclined surface is provided on one side of the movable clamping plate close to the driving seat. Second inclined surfaces corresponding to the two first inclined surfaces are respectively provided on two opposite sides of the driving member, and the second inclined surface is in contact with the first inclined surface.

[0009] As described above, a positioning fixture for a hydraulic plate, the driving member further includes a driving oil cylinder, the driving oil cylinder is fixed on the positioning bottom plate and is connected to the driving seat.

[0010] As described above, a positioning fixture for a hydraulic plate, the positioning mechanism further includes a main positioning seat, a secondary positioning seat and a positioning platform. The main positioning seat and the secondary positioning seat are arranged at intervals on the positioning platform and can both move along their arrangement directions;

[0011] The active turntable is rotatably fixed inside the main positioning seat, and the driven turntable is rotatably fixed inside the secondary positioning seat.

[0012] As described above, a positioning fixture for a hydraulic plate, the positioning platform is provided with a positioning groove arranged in the horizontal direction. Both the main positioning seat and the secondary positioning seat are provided with positioning holes communicating with the positioning groove. The main positioning seat and the secondary positioning seat are respectively located at both ends of the positioning groove, and a positioning bolt is inserted into the communication hole between the positioning hole and the positioning groove.

[0013] As described above, a positioning fixture for a hydraulic plate, the positioning mechanism further includes a rotating motor. The rotating motor is fixed on the main positioning seat, and the output shaft of the rotating motor is connected to the active turntable.

[0014] As described above, a positioning fixture for a hydraulic plate, there are four movable clamping plates and two driving members. Each driving member corresponds to two of the movable clamping plates respectively.

[0015] The utility model has the following beneficial effects:

[0016] 1. Each driving member can synchronously drive two movable clamping plates to move. By cooperating the two movable clamping plates with the two fixed clamping plates, the hydraulic plate can be clamped, or the hydraulic plate can be clamped by two adjacent movable clamping plates. When two hydraulic plates need to be clamped, only one driving member is required, and when three hydraulic plates need to be clamped, two driving members are required. The number of driving members required is less, which can save costs and reduce energy consumption;

[0017] 2. By using the active turntable and the driven turntable to rotate and position the positioning bottom plate, multi-angle processing can be achieved, and the processing efficiency is higher;

[0018] 3. The distance between the active turntable and the driven turntable is adjustable, so the active turntable and the driven turntable can be used to fix positioning bottom plates of different lengths to adapt to synchronous positioning processing of different numbers of hydraulic plates.

[0025] The following are specific embodiments of the present invention and in combination with the attached drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0026] As Figure 1-2 shown, a positioning fixture for a hydraulic plate includes a positioning mechanism 1 and a clamping mechanism 2.

[0027] Among them, the positioning mechanism 1 includes a driving turntable 11, a driven turntable 12 and a positioning base plate 13 located between the driving turntable 11 and the driven turntable 12. The positioning base plate 13 is used to place the clamping mechanism 2 and the hydraulic 3 plate. Then, when the driving turntable 11 rotates, it can drive the positioning base plate 13 to rotate, so as to perform multi-angle processing on the hydraulic plate 3 located on the positioning base plate 13. Moreover, the distance between the driving turntable 11 and the driven turntable 12 is adjustable, which can be applicable to positioning base plates 13 of different lengths. Furthermore, different numbers of clamping mechanisms 2 and hydraulic plates 3 can be arranged on the positioning base plate 13.

[0028] The clamping mechanism 2 includes a fixed clamping plate 21, a movable clamping plate 22 and a driving member 23. The two fixed clamping plates 21 are respectively fixed at both ends of the positioning base plate 13 and are respectively connected to the driving turntable 11 and the driven turntable 12. A plurality of movable clamping plates 22 are arranged at intervals between the two fixed clamping plates 21. The driving member 23 can drive any two adjacent movable clamping plates 22 to move in opposite directions, so that the movable clamping plate 22 close to the fixed clamping plate 21 cooperates with the fixed clamping plate 21 to clamp the hydraulic plate 3 or the two adjacent movable clamping plates 22 approaching each other cooperate to clamp the hydraulic plate 3. It can be realized that one driving member 23 drives two movable clamping plates 22 to perform synchronous displacement. Then, for each additional hydraulic plate 3 to be clamped, two movable clamping plates 22 need to be added, but only one driving member 23 needs to be added, which can reduce the demand for the driving member 23 and thus save costs.

[0029] In this embodiment, there are four movable clamping plates 22 and two driving members 23. Each driving member 23 corresponds to two movable clamping plates 22 respectively. Among them, the two movable clamping plates 22 close to the fixed clamping plate 21 cooperate with the two fixed clamping plates 21 respectively, and can clamp and position the two hydraulic plates 3. The two movable clamping plates 22 moving towards each other can cooperate to clamp and position one hydraulic plate 3.

[0030] Specifically, the driving member 23 includes a driving seat 231. The driving seat 231 is located between two adjacent movable clamping plates 22 and can move towards or away from one side of the positioning base plate 13. A first inclined surface 221 is provided on one side of the movable clamping plate 22 close to the driving seat 231. Second inclined surfaces 231a corresponding to the two first inclined surfaces 221 are provided on two opposite sides of the driving seat 231 respectively. The second inclined surfaces 231a are in contact with the first inclined surfaces 221. In this embodiment, when the driving seat 231 moves towards the side close to the positioning base plate 13, it will squeeze the first inclined surface 221 through the second inclined surface 231a, thereby driving the two movable clamping plates 22 to move away from each other, and then clamping the hydraulic plate 3. When the driving seat 231 moves away from the side of the positioning base plate 13, the second inclined surface 231a will slowly disengage from the first inclined surface 221, and the movable clamping plate 22 can release the clamping of the hydraulic plate 3.

[0031] In order to drive the driving seat 231, the driving member 23 further includes a driving oil cylinder 232. The driving oil cylinder 232 is fixed on the positioning base plate 13 and is connected to the driving seat 231, and the driving oil cylinder 232 is used to drive the driving seat 231 to move.

[0032] In order to position and move the driving turntable 11 and the driven turntable 12, the positioning mechanism 1 further includes a main positioning seat 14, a sub-positioning seat 15 and a positioning platform 16. The main positioning seat 14 and the sub-positioning seat 15 are arranged at intervals on the positioning platform 16 and can both move along its arrangement direction. The driving turntable 11 is rotatably fixed inside the main positioning seat 14, and the driven turntable 12 is rotatably fixed inside the sub-positioning seat 15. Then, when the main positioning seat 14 and the sub-positioning seat 15 move, the distance between them changes, and the distance between the driving turntable 11 and the driven turntable 12 can be adjusted.

[0033] To achieve the adjustment of the distance between the main positioning seat 14 and the secondary positioning seat 15, a positioning groove 161 arranged horizontally is provided on the positioning platform 16. Positioning holes 151 communicating with the positioning groove 161 are provided on both the main positioning seat 14 and the secondary positioning seat 15. The main positioning seat 14 and the secondary positioning seat 15 are respectively located at both ends of the positioning groove 161, and a positioning bolt is inserted into the communication hole between the positioning hole 151 and the positioning groove 161. Then, when it is necessary to adjust the distance between the main positioning seat 14 and the secondary positioning seat 15, only the positioning bolt needs to be removed, and then its position is manually shifted. After it is in place, it is fixed by the positioning bolt.

[0034] To drive the rotation of the active turntable 11 and the positioning base plate 13, the positioning mechanism 1 further includes a rotating motor 17. The rotating motor 17 is fixed on the main positioning seat 14, and the output shaft of the rotating motor 17 is connected to the active turntable 11. The active turntable 11 is driven to rotate by the rotating motor 17, and then the positioning base plate 13 is driven to rotate.
