Abstract
Description
Technical Field
[0001] This utility model relates to the field of square silicon core grinding tape processing technology, and in particular to a clamping fixture for square silicon core grinding tape processing. Background Technology
[0002] A silicon chip refers to a semiconductor chip made of silicon material, also known as a silicon wafer. Silicon is a semiconductor material with excellent electrical conductivity and insulation properties, and can be used to make various electronic components, including transistors and integrated circuits.
[0003] Existing square silicon cores are clamped and fixed during the grinding and tapping process using clamping fixtures. However, traditional clamping fixtures are mostly general-purpose and have poor adaptability to square silicon cores, making it impossible to accurately clamp and fix them, resulting in limited stability. Therefore, we propose a clamping fixture for the grinding and tapping of square silicon cores. Utility Model Content
[0004] The present invention mainly addresses the technical problems existing in the prior art by providing a clamping fixture for the grinding and tapping of square silicon cores.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a clamping fixture for machining square silicon cores, comprising a base, a fixed base, and a movable base. A first clamping seat and a second clamping seat can be assembled on one side of the fixed base and the movable base. A clamping groove is provided on one side of the first clamping seat, and a protective pad is provided on the surface of the clamping groove. A docking seat is installed on the other side of the first clamping seat. The second clamping seat has the same structure as the first clamping seat. Both the fixed base and the movable base have docking grooves inside. Both the fixed base and the movable base have connecting screw grooves that penetrate the docking grooves on their front sides. A locking bolt is threaded into the connecting screw groove. A locking screw groove is provided inside the docking seat.
[0006] Preferably, both the first clamping seat and the second clamping seat can be movably engaged with the mating groove inside the fixed seat and the movable seat via a mating seat.
[0007] Preferably, when adjusting the locking bolt inside the connecting screw groove to the locking screw groove inside the mating seat, the first clamping seat is located on one side of the fixed seat and the movable seat in an assembled and fixed state.
[0008] Preferably, the fixed seat has a connecting groove on one side, and a screw shaft is rotatably connected to the inside of the connecting groove. The movable seat has a drive screw groove inside, and the screw shaft is threadedly connected to the drive screw groove. A control handle is installed at one end of the screw shaft, and a control shaft is rotatably provided on the surface of the control handle.
[0009] Preferably, when the control handle is adjusted by the control shaft to drive the screw shaft to rotate, the movable seat is located outside the screw shaft through the drive screw groove and is in a movable and adjustable state.
[0010] Preferably, a limiting shaft is installed on one side of the fixed seat, a limiting groove is formed inside the movable seat, and one end of the limiting shaft passes through the limiting groove.
[0011] This utility model provides a clamping fixture for machining square silicon cores using a grinding tapered process. It has the following advantages:
[0012] 1. This invention relates to a clamping fixture for the conical grinding of square silicon cores. In this invention, when clamping and processing square silicon cores, a first clamping seat can be installed and connected by inserting it into the mating groove via a mating seat. At this time, the locking bolt inside the connecting screw groove is rotated, causing one end of the locking bolt to be threadedly locked with the locking screw groove inside the mating seat, ensuring the stability of the first clamping seat. The second clamping seat can be installed in the same manner. The first clamping seat can then precisely fit and connect with the square silicon core through the clamping groove, while the second clamping seat can precisely fit and connect with round silicon cores. In this way, the first and second clamping seats can precisely clamp and fix different types of silicon cores, achieving multi-functional clamping while improving the stability of silicon core clamping.
[0013] 2. The clamping fixture for the conical grinding of square silicon cores, when clamping square and round silicon cores of different sizes, can drive the screw shaft to rotate by adjusting the control handle of the control shaft. At this time, the movable seat can slide outside the screw shaft by driving the screw groove. In this way, the fixed seat and the movable seat can stably clamp the silicon core accordingly, thereby achieving the effect of multi-functional clamping. Attached Figure Description

[0022] Example: A clamping fixture for machining square silicon cores using a tapered grinding process, such as... Figures 1-3 As shown, the device includes a base 1, a fixed base 2, and a movable base 3. A first clamping seat 4 and a second clamping seat 8 can be assembled on one side of the fixed base 2 and the movable base 3. A clamping groove 5 is formed on one side of the first clamping seat 4, and a protective pad 6 is provided on the surface of the clamping groove 5. A mating seat 7 is installed on the other side of the first clamping seat 4. The second clamping seat 8 has the same structure as the first clamping seat 4. Both the fixed base 2 and the movable base 3 have mating grooves 9 inside. A connecting screw groove 10 penetrating the mating groove 9 is formed on the front side of both the fixed base 2 and the movable base 3. The internal threads of the connecting screw groove 10... The mating seat 7 is connected with a locking bolt 11. A locking screw groove 12 is opened inside the mating seat 7. A connecting groove 13 is opened on one side of the fixed seat 2. A screw shaft 14 is rotatably connected inside the connecting groove 13. A driving screw groove 15 is opened inside the movable seat 3. The screw shaft 14 is threadedly connected to the driving screw groove 15. A control handle 16 is installed at one end of the screw shaft 14. A control shaft 17 is rotatably provided on the surface of the control handle 16. A limit shaft 18 is installed on one side of the fixed seat 2. A limit groove 19 is opened inside the movable seat 3. One end of the limit shaft 18 passes through the limit groove 19.
[0023] Furthermore, both the first clamping seat 4 and the second clamping seat 8 can be movably engaged with the docking slots 9 inside the fixed seat 2 and the movable seat 3 via the docking seat 7.
[0024] Furthermore, when the locking bolt 11 inside the adjusting connecting screw groove 10 is threadedly connected to the locking screw groove 12 inside the docking seat 7, the first clamping seat 4 is located on one side of the fixed seat 2 and the movable seat 3 in an assembled and fixed state.
