Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically a machining fixture for a zirconia ceramic circular workpiece. Background Technology

[0002] Zirconia ceramics are ceramic materials with zirconium oxide as the main component, usually containing a small amount of hafnium oxide, which is not easily separated. They possess characteristics such as high melting point, high boiling point, high hardness, high resistivity, high refractive index, and low coefficient of thermal expansion. Chemically inert, they are poorly soluble in water, hydrochloric acid, and dilute sulfuric acid. Existing technologies require machining holes on the outer circumferential surface of circular zirconium oxide ceramic workpieces. CNC machining fixtures for machining circular zirconium oxide ceramic workpieces include a three-jaw chuck, a worktable, and a fixing fixture.

[0003] Existing technologies, such as the utility model with authorization publication number CN209903651U, reduce the vibration amplitude of zirconia ceramic circular workpieces during processing, thereby improving processing accuracy.

[0004] Currently, there is a lack of a machining fixture that can easily clamp zirconia ceramic circular workpieces of different lengths and diameters to facilitate machining. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a machining fixture for zirconia ceramic circular workpieces, which can facilitate the clamping of zirconia ceramic circular workpieces of different lengths and diameters to facilitate machining.

[0006] This utility model achieves its purpose through the following technical solution:

[0007] A machining fixture for circular zirconia ceramic workpieces, characterized by comprising: a CNC machine tool with a three-jaw chuck installed inside; a hollow disc fixedly connected to a mounting base, the mounting base being installed inside the CNC machine tool, the hollow disc and the three-jaw chuck being concentrically arranged, and two sets of symmetrical guide plates fixedly connected to the edge of the hollow disc; symmetrical clamping plates, each with a circular slot, the symmetrical clamping plates being fixedly connected to the mounting plates, and the symmetrical mounting plates being fixedly connected to symmetrical guide rods, each guide rod passing through a corresponding guide plate. By using opposing clamping plates, synchronous clamping of the circular zirconia ceramic workpiece from both top and bottom sides is easily achieved. The clamping plates are available in various models with different diameters of their circular slots.

[0008] As a further limitation of this technical solution, the hollow disc bearing is connected to a driven gear, and symmetrical inner round rods are fixedly connected to the edge of the driven gear. Symmetrical mounting plates are respectively fixedly connected to outer round rods, and symmetrical power arms are respectively rotatably connected to the corresponding inner round rods and corresponding outer round rods. By employing a driven gear, the power arm swings when the driven gear rotates, thereby realizing the movement of the clamping plate.

[0009] As a further limitation of this technical solution, the hollow disc is fixedly connected to a motor, the output shaft of the motor passes through the hollow disc, and the output shaft of the motor is fixedly connected to a driving gear, which meshes with the driven gear. By using a motor and gear meshing, the clamping plate is driven to move.

[0010] As a further limitation of this technical solution, the hollow disk is fixedly connected to a center, which passes through the center of the driven gear, and the center is concentrically arranged with the three-jaw chuck. By employing a center, the positioning of a circular zirconia ceramic workpiece is achieved.

[0011] As a further limitation of this technical solution, the mounting base is fixedly connected to the slider of the longitudinal linear module, the longitudinal linear module is fixedly connected to the slider of the transverse linear module, and the transverse linear module is fixedly connected to the CNC machine tool. By using the transverse linear module, it is possible to clamp zirconia ceramic circular workpieces of different lengths. By using the longitudinal linear module, it is convenient to move the clamping plate to the edge of the CNC machine tool and to easily replace different models of clamping plates.

[0012] Compared with related technologies, the machining fixture for zirconia ceramic circular workpieces provided by this utility model has the following beneficial effects:

[0013] (1) This device uses relatively arranged clamping plates to facilitate the synchronous clamping of zirconia ceramic circular workpieces from the top and bottom;

[0014] (2) This device uses a transverse linear module to clamp zirconia ceramic circular workpieces of different lengths;

[0015] (3) This device uses a longitudinal linear module, which makes it easy to move the clamping plate to the edge of the CNC machine tool and to replace different models of clamping plates. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: A machining fixture for a circular zirconia ceramic workpiece includes: a CNC machine tool 1, which has a three-jaw chuck installed inside; a hollow disc 7, fixedly connected to a mounting base 8, the mounting base 8 being installed inside the CNC machine tool 1; the hollow disc 7 being concentrically arranged with the three-jaw chuck; two sets of symmetrical guide plates 12 fixedly connected to the edge of the hollow disc 7; symmetrical clamping plates 4, each having a circular slot 5; the symmetrical clamping plates 4 being fixedly connected to mounting plates 14; the symmetrical mounting plates 14 being fixedly connected to symmetrical guide rods 13, each guide rod 13 passing through a corresponding guide plate 12. By using the oppositely arranged clamping plates 4, it is convenient to simultaneously clamp the circular zirconia ceramic workpiece from both the top and bottom. The clamping plates 4 are available in various models, with different diameters of the circular slots 5.

[0024] The hollow disc 7 is connected to a driven gear 11 by a bearing. Symmetrical inner round rods 17 are fixedly connected to the edge of the driven gear 11. Symmetrical mounting plates 14 are respectively fixedly connected to outer round rods 15. Symmetrical power arms 16 are rotatably connected to the corresponding inner round rods 17 and the corresponding outer round rods 15. By using the driven gear 11, the power arm 16 swings when the driven gear 11 rotates, thereby realizing the movement of the clamping plate 4.

[0025] The hollow disc 7 is fixedly connected to the motor 9, and the output shaft of the motor 9 passes through the hollow disc 7. The output shaft of the motor 9 is fixedly connected to the driving gear 10, and the driving gear 10 meshes with the driven gear 11. By using the motor 9 and the gear meshing, the clamping plate 4 is driven to move.

[0026] The motor 9 is a servo motor HF-KP053K.

[0027] The hollow disk 7 is fixedly connected to the center point 6, which passes through the center of the driven gear 11. The center point 6 is concentrically arranged with the three-jaw chuck. By using the center point 6, the positioning of the zirconia ceramic circular workpiece is achieved.

[0028] The working principle of the machining fixture for zirconia ceramic circular workpieces provided by this utility model is as follows:

[0029] One end of a circular zirconia ceramic workpiece is placed into a three-jaw chuck, with the other end positioned within the area formed by the two clamping plates 4, and the other end in contact with the tip 6. The three-jaw chuck is then used to clamp the circular zirconia ceramic workpiece. The control motor 9 rotates, driving the drive gear 10, which in turn drives the driven gear 11. The driven gear 11 causes the inner rod 17 to swing, which in turn causes the power arm 16 to swing. The power arm 16 then moves the outer rod 15, which in turn moves the mounting plate 14. The mounting plate 14 then moves the guide rod 13 along the guide plate 12, and finally moves the clamping plate 4, thus clamping the circular zirconia ceramic workpiece.

[0030] Example 2: This example further elaborates on Example 1. The mounting base 8 is fixedly connected to the slider of the longitudinal linear module 2, the longitudinal linear module 2 is fixedly connected to the slider of the transverse linear module 3, and the transverse linear module 3 is fixedly connected to the CNC machine tool 1. By using the transverse linear module 3, it is possible to clamp zirconia ceramic circular workpieces of different lengths. By using the longitudinal linear module 2, it is convenient to move the clamping plate 4 to the edge of the CNC machine tool 1, and it is convenient to replace different models of clamping plates 4.

[0031] The model of the longitudinal linear module 2 is FCBX.

[0032] The horizontal linear module 3 is model HMS40 module.

[0033] The working principle of the machining fixture for zirconia ceramic circular workpieces provided by this utility model is as follows:

[0034] By controlling the transverse linear module 3, the distance between the center point 6 and the three-jaw chuck can be adjusted, facilitating the clamping of zirconia ceramic circular workpieces of different lengths. By controlling the longitudinal linear module 2, the clamping plate 4 can be moved to the edge of the CNC machine tool 1, making it easy to change different models of clamping plates 4.
