[0002] A quartz ingot, as a kind of quartz product, is a circular block made of quartz material through a specific processing process. Quartz glass can be processed from the quartz ingot, and quartz glass is widely used in the fields of aerospace, precision optics, lithography technology, semiconductors, etc.

[0003] During the processing of quartz ingots, there is a process of chamfering the circular end face. At present, usually, an operator holds a chamfering machine by hand and cooperates with a fixture and tooling to perform chamfering operations on cylindrical blank parts. This manual chamfering method has the following problems:

[0004] (1) The manual operation intensity is high. The chamfering quality is closely related to the level, concentration, and operation intensity of the operator. The consistency of the chamfering quality is poor, and the chamfering efficiency is low.

[0005] (2) The tooling can only position the blank part, but for the operator of the hand-held chamfering machine, it is impossible to accurately center the workpiece, that is, the operator can only control the chamfering size by vision and measurement. Therefore, it is easy to cause the problem of uneven chamfering size. Summary of the Utility Model

[0015] The beneficial effects of the above embodiments are as follows: By designing a profiling fixture for inserting a cylindrical blank and designing coaxial chamfered holes, the blank can be accurately positioned relative to the grinding wheel, thereby ensuring the consistency of the chamfer size. At the same time, the grinding wheel does not need to be held manually, reducing the interference of human factors and the working intensity of the operator, and thus improving the yield rate and working efficiency.

[0030] Embodiment 1

[0031] As Figure 1 、 2 shown, a circular edge chamfering device includes: a feeding mechanism 1 and a chamfering mechanism 2. The feeding mechanism 1 includes: a guide rail 101, a slider 102, and a profiling template 103. The slider 102 is slidably arranged on the guide rail 101, the profiling template 103 is connected to the slider 102, and the profiling template 103 is provided with a positioning hole for insertion corresponding to a cylindrical blank. The chamfering mechanism 2 is arranged adjacent to the feeding mechanism 1. The chamfering mechanism 2 includes: a driving member 201 and a grinding wheel 202. The driving member 201 has a rotating output end coaxial with the positioning hole, the grinding wheel 202 is connected to the output end, and the grinding wheel 202 is provided with a chamfering hole 203 along the rotation axis. The chamfering hole 203 is a conical structure matching the chamfering angle.

[0032] Specifically, as Figure 1 、 2 shown, the circular edge chamfering device further includes: a frame 3. A workbench 301 is installed at the upper end of the frame 3, and the feeding mechanism 1 and the chamfering mechanism 2 are installed on the workbench 301.

[0033] Specifically, as Figure 2 shown, the feeding mechanism 1 further includes: a handle rod 104, which is connected to the side surface of the slider 102. The axis of the handle rod 104 is perpendicular to the moving direction of the slider 102, and a rubber sleeve is sleeved outside the handle rod 104. By providing the handle rod 104, it is convenient for manual driving of the slider 102 to move.

[0034] Specifically, as Figure 2 shown, the feeding mechanism 1 further includes: a limiting member 105, which is installed on the workbench 301 and is connected to the moving path of the slider 102. The limiting member 105 is used to limit the extreme position of the slider 102 moving towards the grinding wheel 202. By positioning the slider 102 through the limiting member 105, it is convenient for the operator to process the blank to a determined chamfer size, improving work efficiency on the one hand and the consistency of processing accuracy and processing quality on the other hand.

[0035] Specifically, the limiting member 105 is installed on the workbench 301 in an adjustable position along the moving direction of the slider 102. By designing the limiting member 105 into a structure with adjustable position, the grinding wheel 202 can process chamfer structures of different sizes.

[0036] Specifically, as Figure 2 shown, the limiting member 105 is a limiting block. Two parallel mounting holes are vertically opened on the upper end surface of the limiting member 105, and two parallel adjusting holes 302 are opened on the surface of the workbench 301 corresponding to the mounting holes. The adjusting holes 302 are waist-shaped holes and are parallel to the guide rail 101. The threaded end of the bolt passes through the mounting hole and the corresponding adjusting hole 302 and is locked by a nut, thereby positioning the limiting block at the set position.

[0037] Specifically, as Figure 2 shown, the rear end of the profiling template 103 has a connecting shaft, and the connecting shaft is threadedly connected to the threaded hole correspondingly opened in the slider 102. Through this structure, the detachable connection of the profiling template 103 is realized.

[0038] Specifically, as Figure 2 shown, the driving member 201 is a motor, and the output end is the output shaft of the motor. A connecting sleeve is arranged along the rotation axis at the rear end of the grinding wheel 202. The connecting sleeve is sleeved outside the output shaft, and the end surface of the connecting sleeve on one side of the chamfer hole 203 is threadedly connected to the output shaft through a bolt, thereby stably positioning the grinding wheel 202 on the output shaft.

[0039] When this circular chamfering device is working, a cylindrical blank is inserted into the positioning hole. The driving member 201 is started, and the driving member 201 drives the grinding wheel 202 to rotate at a high speed. The operator holds the handle rod 104 and pushes the slider 102 towards the grinding wheel 202. The circular end face of the blank contacts the hole wall of the chamfering hole 203, and the hole wall of the chamfering hole 203 grinds and chamfers the outer periphery of the blank end face. When the slider 102 contacts the limit block, it indicates that the chamfer size of the blank reaches the set value. The operator pulls back the slider 102 to separate the workpiece from the chamfering position, and then pulls out the chamfered product from the template 103.

[0040] Embodiment 2

[0041] Based on Embodiment 1, as Figure 1 shown, the circular chamfering device further includes: a cooling mechanism 4. The cooling mechanism 4 is provided with a water pipe facing the grinding wheel 202, and the water pipe is used to spray coolant on the blank and the grinding wheel 202 during processing. The functions of cooling down and reducing dust are achieved through the cooling mechanism 4.

[0042] Specifically, the cooling mechanism 4 further includes: a water tank. The water tank is connected to the water pipe through a water pump, and the water tank is filled with coolant. The coolant is pressurized by the water pump and then sent into the water pipe, so as to cool down and remove dust during the chamfering process.
