[0013] The nut machining positioning fixture of this utility model has the following advantages compared with the prior art:

[0014] 1. By symmetrically arranging multiple positioning slots on both sides of the positioning seat, and placing multiple clamping seats on both sides of the positioning seat with the clamping slots opposite to the positioning slots, the nut body can be simultaneously embedded in both the clamping slots and the positioning slots. This allows multiple clamping seats to cooperate with the positioning seat to clamp multiple nut bodies, enabling multiple nut bodies to be clamped and positioned in a single clamping operation, thus improving the processing efficiency of the nut body. Furthermore, by simultaneously threading the lead screw to the first and second moving plates, connecting the first connecting rod to both the first and second moving plates, and connecting the second connecting rod to both the second and second moving plates, when the lead screw drives the first and second moving plates to move in opposite or opposite directions, the first and second moving plates respectively drive the connecting plate and the clamping seats to move via the first and second connecting rods.

[0015] 2. By setting multiple elongated first clearance slots on the top of the support frame, with the multiple first clearance slots located on one side of the positioning seat, and allowing multiple first connecting rods to pass through the multiple first clearance slots respectively, the first connecting rods can move within the first clearance slots, thereby avoiding interference between the first connecting rods and the support frame; by setting multiple elongated second clearance slots on the top of the support frame, with the multiple second clearance slots located on the other side of the positioning seat, and allowing multiple second connecting rods to pass through the multiple second clearance slots respectively, the second connecting rods can move within the second clearance slots, thereby avoiding interference between the second connecting rods and the support frame.

[0016] 3. By installing two guide seats on the top of the support frame, the two guide seats are located on both sides of the connecting plate, and the slider passes through the guide groove of the guide seat, so that the slider can move in the guide groove, thereby enabling the guide seat to guide the connecting plate and improve the stability of the movement of the connecting plate and the clamping seat.

[0017] 4. By mounting the handwheel on the outside of the lead screw and positioning it on the outside of the support frame, the lead screw can be rotated via the handwheel, thereby reducing the difficulty of rotating the lead screw and improving the user experience of the product.

[0018] 5. By setting the first empty groove on the side of the positioning groove away from the clamping seat, the bottom of the positioning groove is cleared, allowing the nut body to be embedded in the first empty groove. This avoids the situation where the nut body cannot fit tightly with the positioning groove, resulting in inaccurate positioning of the nut body, thereby improving the machining accuracy of the nut body. Similarly, by setting the second empty groove on the side of the clamping groove away from the positioning seat, the bottom of the clamping groove is cleared, allowing the nut body to be embedded in the second empty groove. This also avoids the situation where the nut body cannot fit tightly with the clamping groove, resulting in inaccurate positioning of the nut body, thereby improving the machining accuracy of the nut body.

[0019] 6. By setting multiple U-shaped mounting slots on both sides of the base plate and positioning these slots on both sides of the support frame, the base plate can be mounted on the worktable of the processing equipment via the mounting slots, thereby reducing the difficulty of mounting the product on the worktable and improving the user experience.

Detailed Implementation

[0025] The following are specific implementation cases and appendices. Figures 1 to 3 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0026] A nut machining positioning fixture, such as Figures 1 to 3 As shown, the nut machining positioning fixture includes: a base plate 10, a support frame 11, a positioning seat 12, a positioning groove 13, a clamping seat 14, a connecting plate 16, a lead screw 17, a first moving plate 18, a first connecting rod 19, a second moving plate 20, and a second connecting rod 21; the support frame 11 is fixed on the base plate 10; the positioning seat 12 is installed on the top of the support frame 11; multiple positioning grooves 13 are symmetrically arranged on both sides of the positioning seat 12; the clamping seat 14 is provided with a clamping groove 15, and multiple clamping seats 14 are located on both sides of the positioning seat 12, with the clamping groove 15 opposite to the positioning groove 13; one end of the connecting plate 16 is connected to the clamping seat 14, and the other end of the connecting plate 16 extends away from the clamping seat 14; the lead screw 17 is symmetrically provided with a first external thread and a second external thread on its outer wall, the first external thread and the second external thread having opposite helical directions, and both ends of the lead screw 17 are connected to the support frame 10. The two sides of the first movable plate 18 are rotatably connected; the first movable plate 18 is provided with a first threaded hole and a first internal thread, and the first threaded hole of the first movable plate 18 is fitted on the outside of the first external thread of the lead screw 17; one end of a plurality of first connecting rods 19 is connected to the top of the first movable plate 18, the plurality of first connecting rods 19 pass through the top of the support frame 11, and the first connecting rods 19 are connected to the connecting plate 16 located on one side of the positioning seat 12; the second movable plate 20 is provided with a second threaded hole and a second internal thread, and the second threaded hole of the second movable plate 20 is fitted on the outside of the second external thread of the lead screw 17; one end of a plurality of second connecting rods 21 is connected to the top of the second movable plate 20, the plurality of second connecting rods 21 pass through the top of the support frame 11, and the second connecting rods 21 are connected to the connecting plate 16 located on the other side of the positioning seat 12.

[0027] By fixing the support frame 11 to the base plate 10 and installing the positioning seat 12 on top of the support frame 11, the base plate 10 supports the support frame 11, thereby supporting the positioning seat 12 and improving the stability of the positioning seat 12. By symmetrically arranging multiple positioning grooves 13 on both sides of the positioning seat 12, multiple clamping seats 14 are located on both sides of the positioning seat 12, and the clamping grooves 15 are opposite to the positioning grooves 13, so that the nut body can be simultaneously embedded in the positioning grooves 13 and the clamping grooves 15. This allows the multiple clamping seats 14 to cooperate with the positioning seat 12 to clamp the multiple nut bodies when the multiple clamping seats 14 move towards the positioning seat 12, thereby improving the stability of the nut body. By connecting one end of the connecting plate 16 to the clamping seat 14 and extending the other end of the connecting plate 16 away from the clamping seat 14, the connecting plate 16 and the clamping seat 14 can move synchronously. By rotatably connecting both ends of the lead screw 17 to the sides of the support frame 11, the support frame 11 supports the lead screw 17, allowing the lead screw 17 to rotate within the support frame 11. By fitting the first threaded hole of the first moving plate 18 onto the outside of the first external thread of the lead screw 17, and fitting the second threaded hole of the second moving plate 20 onto the outside of the second external thread of the lead screw 17, with the helical directions of the first and second external threads opposite, the lead screw 17 drives the first moving plate 18 and the second moving plate 20 to move in opposite or opposite directions when the lead screw 17 rotates, thereby adjusting the distance between the first moving plate 18 and the second moving plate 20. By connecting one end of a plurality of first connecting rods 19 to the top of the first moving plate 18, the plurality of first connecting rods 19 pass through the support frame 11. The top of the support frame 11 is connected to the top of the second moving plate 20, and the multiple first connecting rods 19 are respectively connected to the multiple connecting plates 16 located on one side of the positioning seat 12, so as to realize that the multiple connecting plates 16 are connected to the first moving plate 18 through the first connecting rods 19, so that when the first moving plate 18 moves, the first moving plate 18 can drive the multiple connecting plates 16 to move; by connecting one end of the multiple second connecting rods 21 to the top of the second moving plate 20, the multiple second connecting rods 21 pass through the top of the support frame 11, and the multiple second connecting rods 21 are respectively connected to the multiple connecting plates 16 located on the other side of the positioning seat 12, so as to realize that the multiple connecting plates 16 are connected to the second moving plate 20 through the second connecting rods 21, so as to realize that when the second moving plate 20 moves, the second moving plate 20 can drive the multiple connecting plates 16 to move.

[0028] When using the product, first install it on the worktable of the processing equipment (vertical drilling machine); then, place multiple nut bodies between multiple positioning slots 13 and clamping slots 15 respectively; next, rotate the lead screw 17, causing the lead screw 17 to drive the first moving plate 18 and the second moving plate 20 to move relative to each other, thereby causing the first moving plate 18 and the second moving plate 20 to drive the clamping seat 14 to move towards the positioning seat 12 through the first connecting rod 19 and the second connecting rod 21 respectively, so that the clamping seat 14 cooperates with the positioning seat 12 to clamp the nut body, thereby improving the stability of the nut body; then, start the processing equipment to process the multiple nut bodies.

[0029] By adopting the above structure, multiple positioning grooves 13 are symmetrically arranged on both sides of the positioning seat 12, multiple clamping seats 14 are located on both sides of the positioning seat 12, and the clamping grooves 15 are opposite to the positioning grooves 13, so that the nut body can be simultaneously embedded in the clamping grooves 15 and the positioning grooves 13. This allows multiple clamping seats 14 to cooperate with the positioning seat 12 to clamp multiple nut bodies, thereby enabling multiple nut bodies to be clamped and positioned in one clamping operation, thus improving the processing efficiency of the nut body. Furthermore, by simultaneously threading the lead screw 17 to the first moving plate 18 and the second moving plate 20, connecting the first connecting rod 19 to both the first moving plate 18 and the connecting plate 16, and connecting the second connecting rod 21 to both the second moving plate 20 and the connecting plate 16, when the lead screw 17 drives the first moving plate 18 and the second moving plate 20 to move in opposite or opposite directions, the first moving plate 18 and the second moving plate 20 respectively drive the connecting plate 16 and the clamping seat 14 to move via the first connecting rod 19 and the second connecting rod 21. This eliminates the need for multiple drive devices to drive multiple clamping seats 14 separately, thereby reducing the production cost of the product.

By connecting both ends of the optical rod 27 to the support frame 11 and allowing the optical rod 27 to pass through the first moving plate 18 and the second moving plate 20 in sequence, the support frame 11 can support the optical rod 27, thereby enabling the first moving plate 18 and the second moving plate 20 to move along the optical rod 27, thus preventing the first moving plate 18 and the second moving plate 20 from shifting during movement and improving the stability of the movement of the first moving plate 18 and the second moving plate 20.
