Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a multi-axial rapid positioning machine for a quick clamping fixture used in lathe machining. Background Technology

[0002] A fixture is a device used to fix, position, and support a workpiece. In the field of lathe machining, most fixtures used are three-jaw chucks or four-jaw chucks. By the radial movement of the three movable jaws evenly distributed on the chuck body, the workpiece is clamped and positioned, and shaft-type workpieces can be clamped tightly and quickly.

[0003] Most existing chuck-type fixtures can only hold workpieces in a longitudinal position. When it is necessary to mill both ends of the workpiece, the workpiece needs to be removed and its orientation changed before it can be clamped again. Therefore, the workpiece needs to be positioned twice, which reduces the processing efficiency. Utility Model Content

[0004] The main purpose of this utility model is to provide a multi-axial rapid positioning machine for a quick clamping fixture for lathe machining. It can effectively solve the problem that most existing chuck-type fixtures can only clamp the workpiece in the longitudinal position. When it is necessary to mill both ends of the workpiece, the workpiece needs to be taken out and the direction changed to clamp it again. Therefore, the workpiece needs to be positioned twice, which leads to a decrease in machining efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] A multi-axial rapid positioning machine for quick clamping fixtures used in lathe machining includes a chuck body, a longitudinal positioning groove, a transverse positioning groove, a fixture one, a fixture two, a movable clamping plate, a drive assembly, and a positioning assembly.

[0007] The longitudinal positioning groove is located at the center of the chuck body, and the transverse positioning groove is located on the surface of the chuck body. The longitudinal positioning groove and the transverse positioning groove are perpendicular to each other.

[0008] Both clamp one and clamp two are movably connected to the outside of the chuck body, and clamp one and clamp two are centrally symmetrical about the longitudinal positioning groove as the axis.

[0009] The movable clamp is rotatably connected to the inner end of clamp two;

[0010] Both the driving component and the positioning component are located inside the chuck body, with the positioning component situated between the driving component and the second clamp.

[0011] Preferably, the drive assembly includes a drive disk and a chuck;

[0012] The drive disk is rotatably connected to the inside of the chuck body, and the surface of the drive disk is provided with a planar thread;

[0013] Both clamp one and clamp two are fixedly connected to the inner side with claws, and the claws are engaged with the planar thread.

[0014] Preferably, the positioning component includes a rotating ring, a connecting rod, a limiting frame, a limiting block, and a fixed shaft;

[0015] The rotating ring is rotatably connected inside the chuck body, and the rotating ring is located between the second clamp and the drive disk;

[0016] The connecting rod is fixedly connected to the outside of the rotating ring, and the other end of the connecting rod is fixedly connected to the limiting frame;

[0017] The limiting block is fixedly connected to the inner side of the movable clamping plate, and the limiting block is located inside the limiting frame;

[0018] The fixed shaft is fixedly connected to the limiting frame, and the fixed shaft is rotatably connected inside the chuck body.

[0019] Preferably, a touch switch is provided inside the transverse positioning groove. The touch switch is used to drive a micro motor installed on the inner wall of the chuck body. The output shaft of the micro motor is fixedly connected to a gear, and the outer wall of the rotating ring is provided with a toothed groove that meshes with the gear.

[0020] The beneficial effects of this utility model are:

[0021] This invention rotates the movable clamping plate to an angle parallel to the first clamp, allowing the movable clamping plate and the first clamp to fit tightly against the surface of a horizontally placed shaft-like workpiece, thereby improving the firmness of the workpiece clamping. When it is necessary to process both ends of the shaft-like workpiece, placing the workpiece in the horizontal positioning groove will expose both ends of the workpiece to the outside of the chuck body, thus allowing the workpiece to be processed in one go. Depending on different processing requirements, the workpiece can be placed horizontally or vertically, thereby achieving multi-axial positioning and clamping of shaft-like workpieces.

[0028] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] This application designs a multi-axial rapid positioning machine for a quick-clamping fixture used in lathe machining, as shown in the attached figure. Figs. 1-3 As shown, it includes a chuck body 1, a longitudinal positioning groove 2, a transverse positioning groove 3, a first clamp 5, a second clamp 6, a movable clamping plate 7, a drive assembly, and a positioning assembly;

[0030] The longitudinal positioning groove 2 is located at the center of the chuck body 1, and the transverse positioning groove 3 is located on the surface of the chuck body 1. The longitudinal positioning groove 2 and the transverse positioning groove 3 are perpendicular to each other.

[0031] Both clamp 1 5 and clamp 2 6 are movably connected to the outside of the chuck body 1. Clamp 1 5 and clamp 2 6 are centrally symmetrical about the longitudinal positioning groove 2. Clamp 1 5 is perpendicular to the transverse positioning groove 3.

[0032] The movable clamping plate 7 is rotatably connected to the inner end of the second clamping fixture 6. Both the movable clamping plate 7 and the inner end of the first clamping fixture 5 are equipped with rubber anti-slip pads, which can increase the friction between the workpiece and the workpiece, thereby improving the firmness of the workpiece clamping.

[0033] Both the drive component and the positioning component are located inside the chuck body 1, with the positioning component located between the drive component and the fixture 6.

[0034] Furthermore, the drive components include a drive disk 8 and a chuck 11;

[0035] The drive disk 8 is rotatably connected inside the chuck body 1. The surface of the drive disk 8 is provided with a flat thread. The drive disk 8 can be driven by a motor or a hydraulic cylinder, and the rotation axis of the drive disk 8 coincides with the center of the longitudinal positioning groove 2.

[0036] Both clamp 5 and clamp 6 have chucks 11 fixedly connected to their inner sides. The chucks 11 are engaged with the planar thread. The chucks 11, drive disk 8, clamp 5 and clamp 6 together form the existing three-jaw chuck. When a shaft workpiece is placed in the longitudinal positioning groove 2, the workpiece can be clamped by clamp 5 and the movable clamping plate 7 that is tightly fitted with clamp 6, thereby realizing multi-axial positioning and clamping of the workpiece.

[0037] Furthermore, the positioning assembly includes a rotating ring 9, a connecting rod 10, a limiting frame 13, a limiting block 14, and a fixed shaft 15;

[0038] The rotating ring 9 is rotatably connected inside the chuck body 1, and the rotating ring 9 is located between the clamp 6 and the drive disk 8;

[0039] The connecting rod 10 is fixedly connected to the outside of the rotating ring 9, and the other end of the connecting rod 10 is fixedly connected to the limiting frame 13;

[0040] The limiting block 14 is fixedly connected to the inner side of the movable clamping plate 7. The limiting block 14 is located inside the limiting frame 13. The outer contour lines of the limiting block 14 are all rounded, which can prevent it from getting stuck in the limiting frame 13 and improve the smoothness of the mechanism's operation.

[0041] The fixed shaft 15 is fixedly connected to the limiting frame 13, and the fixed shaft 15 is rotatably connected inside the chuck body 1.

[0042] Furthermore, a touch switch 4 is provided inside the transverse positioning groove 3. The touch switch 4 is used to drive a micro motor installed on the inner wall of the chuck body 1. The output shaft of the micro motor is fixedly connected to a gear 12, and the outer wall of the rotating ring 9 is provided with a toothed groove that meshes with the gear 12.

[0043] Working principle: When machining both ends of a shaft-type workpiece is required, the workpiece is placed horizontally in the horizontal positioning groove 3. The workpiece touches the touch switch 4 and starts the micro motor and gear 12. The gear 12 drives the rotating ring 9 to rotate, and the rotating ring 9 drives the connecting rod 10 and the limiting frame 13 to rotate. The limiting frame 13 drives the limiting block 14 and the movable clamping plate 7 to rotate around the fixed shaft 15 until the movable clamping plate 7 rotates to the same direction as the first clamping fixture 5. Then, the drive disk 8 drives the chuck 11 to move through the planar thread, so that the first clamping fixture 5 and the second clamping fixture 6 approach each other. At this time, the first clamping fixture 5 and the movable clamping plate 7 are both perpendicular to the workpiece, so that the movable clamping plate 7 can fit tightly with the workpiece, thereby clamping the workpiece.

[0044] The above embodiments are only some embodiments of this utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the protection scope of this utility model.
