Description

Technical Field

[0001] This utility model relates to the field of ceramic processing equipment, and in particular to a ceramic inner circle grinding device. Background Technology

[0002] Ceramic injection molding is an advanced manufacturing technology that combines polymer injection molding with ceramic preparation processes. This technology is widely used in aerospace, electronics, and medical fields, and boasts the ability to mold complex shapes with high precision. Its process mainly includes the following steps: 1. Pre-fabrication: Select suitable ceramic powder and binder, and prepare the mixture.

[0003] 2. Injection molding: The mixture is injected into a mold to form the desired shape.

[0004] 3. Degreasing: Remove the binder to improve the density of the ceramic.

[0005] 4. Sintering: Sintering ceramics at high temperatures to enhance their mechanical properties and stability.

[0006] After the ceramic product is sintered, for precision ceramic parts, it is necessary to clamp and grind their inner circles again to protect the precision of the ceramic parts. However, the existing inner circle grinding equipment generally suffers from poor versatility and is difficult to apply to ceramic parts with different structures. In addition, during the grinding process, coolant is used for heat dissipation. The way coolant is added on the market is to directly spray the coolant onto the workpiece using a universal joint pipe. This heat dissipation method is likely to cause the universal joint pipe to shift during the processing, resulting in the coolant not being sprayed accurately onto the workpiece, affecting the heat dissipation effect and processing quality.

[0028] like Figure 1-3 As shown, the present invention provides a ceramic inner circle grinding device, including a frame 1, on which a spindle support 2 is fixedly installed, a rotating spindle 3 is rotatably installed inside the spindle support 2, and a three-jaw chuck 4 is fixedly installed on the rotating spindle 3; An X-axis slide table 5 is slidably mounted on the frame 1, and a Y-axis slide table 6 is slidably mounted on the X-axis slide table 5. The X-axis slide table 5 drives the Y-axis slide table 6 to move left and right, and an inner circle grinding fixture 7 is fixedly mounted on the Y-axis slide table 6. The inner grinding fixture 7 includes a heat dissipation cylinder 71 and a tool locking bolt 72. The Y-axis slide 6 drives the heat dissipation cylinder 71 to move back and forth. The outer side of the heat dissipation cylinder 71 near the three-jaw chuck 4 has a bolt hole 8 formed. The tool locking bolt 72 is screwed and installed in the bolt hole 8. A baffle 9 is formed on the inner side of the left end of the heat dissipation cylinder 71, and a water cooling interface 10 is provided on the heat dissipation cylinder 71. The water cooling interface 10 delivers coolant into the heat dissipation cylinder 71.

[0029] The principle is as follows: the X-axis slide 5 is used to adjust the left and right position of the inner grinding fixture 7, and the Y-axis slide is used to adjust the front and back position of the inner grinding fixture 7. The cutting tool is installed in the heat dissipation cylinder 71 of the inner grinding fixture 7 and locked by the cutting tool locking bolt 72. In addition, the hollow ceramic part is clamped in the three-jaw chuck 4 of the rotating spindle 3. During inner grinding, the cutting tool is inserted into the rotating hollow ceramic part. The Y-axis slide 6 is used to adjust the front and back position of the cutting tool to realize the inner grinding feed. In addition, the heat dissipation cylinder 71 has a water cooling interface 10, and the water cooling interface 10 can be connected to coolant and delivered to the heat dissipation cylinder 71 to dissipate heat from the cutting tool. The baffle 9 can control the direction of coolant flow, so that the coolant can fully cool the cutting tool during grinding and ensure the service life of the cutting tool.

[0030] Furthermore: the baffle 9 has a semi-circular structure and is positioned at the bottom edge of the left side of the heat dissipation cylinder 71; when the coolant pressure is high, since the semi-circular baffle 9 can only supply the lower half of the ball heat dissipation cylinder 71, a small amount of coolant will flow out from the left end of the heat dissipation cylinder 71, while most of the coolant will flow out after passing through the cutter assembled at the right end of the heat dissipation cylinder 71, thus achieving rapid water cooling.

[0031] Furthermore: an X-axis guide rail 11 is fixedly installed on the frame 1, an X-axis slider 12 is slidably installed on the X-axis guide rail 11, an X-axis slide 5 is fixedly installed on the X-axis slider 12, two positioning blocks 13 are fixedly installed on the frame 1, an X-axis screw 14 is rotatably installed between the two positioning blocks 13, a movable block 15 is fixedly installed on the X-axis slide 5, a first threaded hole 16 is formed in the movable block 15, and the X-axis screw 14 is bolted into the first threaded hole 16; the X-axis slide 5 can be driven to move left and right by twisting the X-axis screw 14. Due to the setting of the X-axis guide rail 11 and the X-axis slider 12, the stability of the X-axis slide 5 during left and right translation can be guaranteed.

[0032] Furthermore, an X-axis rotary handle 17 is fixedly installed on the left end of the X-axis screw 14, which facilitates the twisting of the X-axis screw 14 and thus quickly controls the X-axis slide 5 to move left and right.

[0033] Furthermore: A Y-axis guide rail 18 is fixedly installed on the X-axis slide 5, and a Y-axis slider 19 is slidably installed on the Y-axis guide rail 18. The Y-axis slide 6 is fixedly installed on the Y-axis slider 19. Side plates 20 are fixedly installed at the front and rear ends of the X-axis slide 5, and a Y-axis screw 21 is rotatably installed between the two side plates 20. A second threaded hole 22 is formed on the Y-axis slider 19, and the Y-axis screw 21 is helically installed in the second threaded hole 22. The Y-axis slide 6 can be driven to move back and forth by twisting the Y-axis screw 21. Due to the setting of the Y-axis guide rail 18 and the Y-axis slider 19, the stability of the Y-axis slide 6 during back and forth translation can be guaranteed.

[0034] Furthermore, a Y-axis rotary handle 23 is fixedly installed at the front end of the Y-axis screw 21, which facilitates twisting the Y-axis screw 21 and thereby quickly controls the Y-axis slide 6 to move forward and backward.

[0035] Furthermore, the second threaded hole 22 is provided through the heat dissipation cylinder 71; it can limit the installation angle of the heat dissipation cylinder 71 and prevent the heat dissipation cylinder 71 from rotating when the tool is grinding the inner circle of the hollow ceramic part, thereby ensuring the accuracy of the inner circle grinding.

[0036] Furthermore: a spindle motor 24 is fixedly installed inside the spindle bracket 2, and the spindle motor 24 drives the rotating spindle 3 to rotate; this ensures the high-speed operation of the rotating spindle 3, and the hollow ceramic parts can be ground on the inner circle under high-speed operation.

[0037] Furthermore: a first pulley 25 is fixedly installed on the rotor of the main spindle motor 24, and a second pulley 26 is fixedly installed on the end of the rotating main spindle 3 away from the three-jaw chuck 4. A transmission belt 27 is installed between the first pulley 25 and the second pulley 26; thus, the stability of the main spindle motor 24 driving the rotating main spindle 3 is improved.

[0038] Furthermore, there are two or more bolt holes 8, arranged in a circular array on the outer periphery of the heat dissipation cylinder 71. The number of tool locking bolts 72 is the same as the number of bolt holes 8, and each tool locking bolt 72 is screwed into the bolt hole 8. The tool can be locked in the heat dissipation cylinder 71 by using the tool locking bolts 72 in the multiple bolt holes 8. At the same time, the eccentric position of the tool in the heat dissipation cylinder 71 can be changed by adjusting the locking bolts. It can also be used for clamping tools of different sizes, so as to achieve precise internal hole machining of hollow ceramic parts.

[0039] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
