[0025] Example: Refer to Figure 1-Figure 3 , a machining positioning device, comprising,

[0026] Processing table 1, the top surface of which is fixedly connected with a positioning frame;

[0027] The positioning assembly includes a positioning plate 2, which is arranged on a positioning frame. The positioning frame is provided with a locking member that can switch between a locked and unlocked state. When the locking member is in the locked state, the positioning plate 2 is fixed to the positioning frame. When the locking member is in the unlocked state, the positioning plate 2 is raised and lowered relative to the positioning frame.

[0028] The clamping member includes two clamping plates 3 arranged on the positioning plate 2, and the clamping plates 3 are slidably engaged with the positioning plate 2;

[0029] The adjusting member is provided on the positioning plate 2 and is connected to the two clamping plates 3 respectively so as to move the two clamping plates 3 toward or away from each other.

[0030] The utility model fixes a positioning frame on the processing table 1 and arranges a positioning plate 2 on the positioning frame, and uses the locking piece arranged corresponding to the positioning plate 2 to adjust the movement state of the positioning plate 2. When the locking piece is unlocked, the positioning plate 2 can be raised and lowered along the positioning frame, thereby expanding the scope of application for reinforcing the workpiece to be positioned. When the locking piece is locked, the positioning plate 2 can be fixed to the positioning frame, so that when the fixed workpiece is processed, its positioning stability can be effectively guaranteed, and the adjustment piece is used to control the two clamping plates 3 to move toward or oppositely to achieve clamping of the workpiece.

[0031] Furthermore, the adjusting part includes a bidirectional screw 4, a sliding groove is opened on the top surface of the positioning plate 2, the bidirectional screw 4 is arranged in the sliding groove, the bottom end of the splint 3 extends into the sliding groove and is fixed with a connecting block 5, and the two connecting blocks 5 are respectively located on both sides of the bidirectional screw 4 and are threadedly connected to the bidirectional screw 4. A driving part connected to the bidirectional screw 4 is provided on the positioning plate 2, and the bidirectional screw 4 is connected to the positioning plate 2 through the driving part.

[0032] The driving member is connected to the bidirectional screw 4 to control the rotation of the bidirectional screw 4 and the positioning plate 2. The different rotation directions of the bidirectional screw 4 are used to drive the two connecting blocks 5 and the clamping plates 3 to perform clamping movement, and the rubber layer 10 can be selectively fixed to the sides of the two clamping plates 3 that are close to each other to improve the clamping stability and avoid scratching the workpiece.

[0033] Furthermore, the driving member includes a rotating rod 6 connected to one side of the positioning plate 2, one end of the rotating rod 6 extends into the positioning plate 2 and is fixedly connected to a first bevel gear 7, one end of the bidirectional screw 4 extends out of the slide groove and is fixedly connected to a second bevel gear 8, and the first bevel gear 7 is engaged with the second bevel gear 8.

[0034] Furthermore, a hand wheel 9 is fixedly connected to one end of the rotating rod 6 away from the positioning plate 2 .

[0035] Reference Figure 2By rotating the hand-cranked wheel 9, the rotating rod 6 is driven to rotate, and the rotating rod 6 rotates the first bevel gear 7 to drive the second bevel gear 8 to rotate, and the second bevel gear 8 drives the bidirectional screw 4 to rotate to realize the movement of the two splints 3. During the process, the connecting block 5 is threadedly connected to the bidirectional screw 4, and the bidirectional screw 4 is connected to the rotating rod 6 through the first bevel gear 7 and the second bevel gear 8. A locking structure is formed through gear transmission, which effectively reduces the unstable clamping of the splint 3 caused by external vibration force during processing, and further improves positioning stability.

[0036] Furthermore, the positioning frame includes two support plates 11 relatively fixed to the top surface of the processing table 1, and at least one limiting groove is opened on the support plate 11, and a lifting seat 12 is arranged in the limiting groove. The two ends of the positioning plate 2 are respectively fixed to at least two relatively arranged lifting seats 12, wherein a lifting member is provided in any limiting groove on the support plate 11 on the same side, and the lifting member is used to drive the adjacent lifting seats 12 to rise and fall along the limiting groove, and the locking member is arranged on the remaining lifting seats 12 away from the lifting member.

[0037] Through the limiting grooves opened on the support plate 11, the limiting columns 19 are fixed on both sides of the lifting seat 12 that slides in the limiting grooves, so that the lifting seat 12 and the support plate 11 are limited and slidably connected. By using several lifting seats 12 on both sides to be fixedly connected with the positioning plate 2, the positioning plate 2 is erected between the support plates 11, and the lifting seat 12 is driven by the lifting member to drive the positioning plate 2 to rise and fall relative to the processing table 1. When it is lifted to the appropriate position, the remaining lifting seats 12 are locked with the support plate 11 by the locking member to achieve the fixation of the positioning plate 2 and the support plate 11.

[0038] Furthermore, the locking member includes at least one screw 13 arranged on the lifting seat 12, and an empty slot is opened in the lifting seat 12 corresponding to the screw 13. One end of the screw 13 extends into the empty slot and is threadedly connected to the lifting seat 12. A wedge block 15 is slidably connected in the empty slot. One end of the screw 13 extending into the empty slot is connected and adapted to the wedge block 15. The wedge block 15 extends out of the lifting seat 12 through the screw 13 and abuts against the inner wall of the limit slot. A reset member is provided between the wedge block 15 and the lifting seat 12.

[0039] Furthermore, the reset member includes a spring 17. A slot is provided on the side wall of the wedge block 15. One end of the spring 17 is fixed in the slot, and the other end of the spring 17 extends out of the slot and is fixed to the inner wall of the adjacent empty slot.

[0041] Reference Figure 3The screw 13 is rotated by the rotating wheel 14 fixed to the screw 13, and the screw 13 rotates and extends into the empty slot and slides in contact with the oblique edge of the wedge block 15, squeezing the wedge block 15 out of the empty slot, and the abutment 16 fixed to the side wall of the wedge block 15 abuts against the inner wall of the limiting slot, thereby fixing the lifting seat 12 together with the positioning plate 2 and the support plate 11. After the screw 13 is rotated in the opposite direction so that it no longer abuts against the wedge block 15, under the elastic action of the spring 17, the wedge block 15 slides back to its original position and the abutment 16 extends into the lifting seat 12, avoiding affecting the lifting of the lifting seat 12 along the limiting slot.

[0042] The working process of this embodiment is as follows:

[0043] Place the workpiece on the positioning plate 2, and use the hand-cranked wheel 9 to drive the rotating rod 6 to rotate. The rotating rod 6 rotates the bidirectional screw 4 to make the two clamping plates 3 move toward each other to clamp the workpiece, and then start the oil cylinder 18 to drive the adjacent lifting seat 12 to move up and down. When the workpiece reaches a suitable height under the lifting of the positioning plate 2, the rotating wheel 14 is used to rotate the screw 13. The screw 13 contacts the wedge block 15 to make the abutting protrusion 16 extend out of the lifting seat 12 and abut against the inner wall of the limit groove, thereby fixing the positioning plate 2 and effectively ensuring the stability of the positioning device when processing the workpiece.
