Description

A ceramic chopping knife outer chamfering grinding device Technical Field

[0001] This utility model relates to the field of grinding device technology, and in particular to a grinding device for the outer chamfering of ceramic chopping tools. Background Technology

[0002] A ceramic bonding tool, also known as a ceramic nozzle, is an axisymmetric ceramic tool with a vertically oriented hole. It belongs to the category of precision microstructure ceramic components. In application, the ceramic bonding tool is used as a wire bonding tool in the wire bonding process. It can be used for bonding and packaging circuits such as silicon controlled rectifiers, surface acoustic waves, LEDs, diodes, transistors, and IC chips. As a welding needle in a bonding machine, the ceramic bonding tool is like the "sewing needle" in a sewing machine used to thread the needle. The metal wire needs to pass through it to bond one chip to another chip or substrate.

[0003] When processing ceramic chopping knives, the outer chamfer needs to be ground to make it smoother. Grinding is mainly carried out using a fixture and a grinding mechanism. For example, Chinese Patent Publication No. CN114789401A discloses "a grinding device for grinding the outer chamfer of ceramic chopping knives". It drives the automatic feed base plate to move through the feed moving component. The product spindle drives the ceramic chopping knife to rotate at high speed. The grinding mechanism plays a grinding role. The grinding spindle drives the grinding wheel to rotate at high speed. The adjusting rod adjusts the horizontal position of the grinding spindle and improves the grinding accuracy of the outer chamfer of the ceramic chopping knife.

[0004] However, in actual use, when the grinding device grinds ceramic chopping tools, it can only grind one ceramic chopping tool at a time, resulting in low processing efficiency and affecting output. Summary of the Invention

[0005] The purpose of this invention is to solve the shortcomings of existing technologies, such as the fact that only one ceramic chamfer can be ground during grinding, resulting in low processing efficiency and reduced output. Therefore, this invention proposes a ceramic chamfer external chamfer grinding device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A ceramic chamfering grinding device is designed, comprising a processing table and a spindle chuck. A mounting cover is fixedly mounted on the processing table, and a drive structure is disposed inside the mounting cover. Multiple spindle chucks are disposed on the mounting cover. Multiple mounting components corresponding to the spindle chucks are disposed on the processing table. Each mounting component is threadedly connected to a grinding part that mates with the ceramic chamfer. A drive disk that is rotatably mounted on the processing table and is poweredly connected to the multiple mounting components is disposed on the processing table. A positioning structure that mates with the drive disk is disposed on the processing table.

[0008] Furthermore, the mounting assembly includes a mounting bracket, each mounting bracket being provided with a mounting seat, and each mounting seat having a threaded hole corresponding to the grinding part.

[0009] Furthermore, a support frame is fixedly installed on the processing table, and the mounting frame is slidably connected to the support frame.

[0010] Furthermore, the drive disk has multiple inclined slots, and the mounting bracket has multiple insert rods that cooperate with the inclined slots.

[0011] Furthermore, the drive structure includes a main gear that is powered by the motor, and each spindle chuck is provided with a driven gear that meshes with the main gear.

[0012] Furthermore, the positioning structure includes a limiting member that is movably inserted into the processing table and cooperates with the drive disk. The limiting member is provided with a guide groove. A limiting plate that is movably inserted into the guide groove is fixedly provided on the processing table. A spring is provided between the limiting plate and the guide groove.

[0013] The ceramic chamfering grinding device proposed in this utility model has the following advantages:

[0014] In this utility model, by setting multiple spindle chucks and multiple corresponding mounting components, and setting grinding parts on each mounting component, multiple ceramic chopping tools can be ground simultaneously in one processing, which greatly improves grinding efficiency and thus increases production output.

[0015] Secondly, in this invention, multiple grinding parts are moved simultaneously by rotating the drive disk, which is more synchronized. Furthermore, the drive structure enables one motor to drive multiple ceramic cutting tools to rotate at the same time, avoiding the need for a separate motor to drive each spindle chuck, thus effectively reducing costs.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Referring to Figures 1-4, a ceramic chamfering grinding device includes a processing table 1 and a spindle chuck 4. A mounting cover 2 is fixedly installed on the processing table 1, and a drive structure 3 is installed inside the mounting cover 2. Multiple spindle chucks 4 are installed on the mounting cover 2. Multiple mounting components 5 corresponding to the spindle chucks 4 are installed on the processing table 1. Each mounting component 5 is threadedly connected to a grinding part 6 that mates with the ceramic chamfer. A drive disk 7 that is rotatably connected to the multiple mounting components 5 is installed on the processing table 1. A positioning structure 8 that mates with the drive disk 7 is installed on the processing table 1.

[0023] In this invention, multiple spindle chucks 4 and multiple corresponding mounting components 5 are provided, and each mounting component 5 is equipped with a grinding element 6. By rotating the drive disk 7, multiple grinding elements 6 are moved simultaneously, thereby grinding multiple ceramic cutting tools in one processing cycle, which greatly improves grinding efficiency and increases production output.

[0024] Furthermore, in this embodiment, the mounting component 5 includes a mounting bracket 51, and each mounting bracket 51 is provided with a mounting seat 52. Each mounting seat 52 has a threaded hole corresponding to the grinding part 6. The grinding part 6 is threadedly connected to the mounting seat 52. When the grinding part 6 is severely worn, the worn grinding part 6 can be removed and replaced with a new grinding part.

[0025] Furthermore, in this embodiment, a support frame 53 is fixedly installed on the processing table 1, and the mounting frame 51 is slidably connected to the support frame 53. The mounting frame 51 can move along the support frame 53, thereby driving the grinding part 6 to approach or move away from the ceramic chopping knife.

[0026] It should be noted that in this embodiment, the drive disk 7 is provided with multiple inclined slots 71, and the mounting bracket 51 is fixedly provided with multiple insert rods 54 that cooperate with the inclined slots 71. When the drive disk 7 rotates, the position of the inclined slots 71 changes, thereby driving the insert rods 54 to move the mounting bracket 51 and the grinding part 6.

[0027] Furthermore, in this embodiment, the drive structure 3 includes a main gear 32 that is powered by the motor 31, and a driven gear 33 that meshes with the main gear 32 is provided on the spindle chuck 4. The motor 31 drives the main gear 32 to rotate, and at the same time drives multiple driven gears 33 to rotate. The main gear 32 and the driven gears 33 are preferably bevel gears.

[0028] More specifically, in this embodiment, the positioning structure 8 includes a limiting member 81 that is movably inserted into the processing table 1 and cooperates with the drive disk 7. The limiting member 81 is provided with a guide groove. A limiting plate 82 that is movably inserted into the guide groove is fixedly provided on the processing table 1. A spring 83 is provided between the limiting plate 82 and the guide groove. When the drive disk 7 rotates to the point where the grinding part 6 is in contact with the ceramic chopping knife for grinding, the spring 83 pulls the limiting member 81 upward, locking the drive disk 7 to prevent its rotation from causing the grinding part 6 to separate from the ceramic chopping knife.

[0029] Working method: During operation, the rotating drive disk 7 changes the position of the inclined groove 71, which in turn drives the insertion rod 54 to move the mounting bracket 51 and the grinding part 6 to fit closely to the ceramic chopping knife. The spring 83 pulls the limiting part 81 to move upward and lock the drive disk 7. The motor 31 drives the main gear 32 to rotate, and at the same time drives multiple driven gears 33 to rotate. The rotation of the driven gears 33 drives the main shaft chuck 4 and the ceramic chopping knife to rotate for grinding.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
