Description

Technical Field

[0001] This utility model belongs to the field of glass rod polishing technology, specifically relating to a small rod-shaped glass side polishing device. Background Technology

[0002] In the field of precision manufacturing, brittle rod-shaped products such as ceramic rods, quartz tubes, and glass rods often face technological challenges due to "premature fracture" during non-contact processing such as wire cutting and laser cutting. These materials have extremely low fracture strain (typically less than 0.5%, such as only 0.1% for alumina ceramics). When the cutting nears its end, the remaining cross-sectional area of ​​the material cannot withstand the instantaneous thermal or mechanical stress, leading to sudden fracture 10-50 μm before the programmed end point, forming a 0.05-0.3 mm high protrusion. This "end protrusion" not only disrupts the coaxiality of the cylindrical surface (with an error of ±15 μm) but also causes stress concentration in subsequent processing, becoming a potential source of product failure.

[0003] To remove such protrusions, the main machining methods are grinding wheel grinding and CNC milling: Grinding wheel grinding uses resin-bonded or metal-bonded diamond grinding wheels (such as 1V1 resin-bonded diamond integral edge grinding wheels) and completes the process in three stages: rough grinding, fine grinding and polishing. However, due to stress concentration, it is prone to breakage and edge chipping in the rough grinding stage. CNC milling is suitable for precision parts with complex boss structures that require multi-face machining (such as optical lens bosses). It has high machining accuracy and high yield, but the cost is relatively high.

[0004] For small glass rods (e.g., less than 3mm in diameter) with protrusions, their small size makes them inconvenient to hold by hand, resulting in low efficiency, high difficulty, and a high risk of breakage when polished manually. Directly using a grinding wheel for rough grinding also easily leads to breakage and chipping. However, if tooling is used to perform preliminary polishing of these small glass rod protrusions, reducing their size and stress during grinding, the product yield can be significantly improved, while also avoiding the low efficiency of purely manual polishing. Utility Model Content

[0005] The purpose of this invention is to provide a small rod-shaped glass side polishing device to solve the problems of low efficiency, high difficulty and easy breakage in existing small glass rod polishing.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A small rod-shaped glass side polishing device includes a base, on which a polishing table is provided. A placement groove is provided on the upper surface of the polishing table along the length direction of the polishing table. A glass rod to be polished is placed in the placement groove. End face guards for pressing the end face of the glass rod to be polished are provided on the front and rear end faces of the polishing table. Side guards for pressing the side of the glass rod to be polished are provided on both sides of the placement groove on the upper surface of the polishing table. A polishing rod is placed in the gap between the two side guards.

[0008] Furthermore, the side guard is covered with soft silicone on the side near the glass rod to be polished.

[0009] Furthermore, the placement groove is provided in two sets.

[0010] Furthermore, the polishing rod includes a polishing part and a handheld part connected above the polishing part.

[0011] Furthermore, the polishing table can be detachably mounted on the base.

[0012] Furthermore, the end face retainer includes a mounting plate, which is mounted on a grinding table by screws. The mounting plate has a first mounting hole, in which a compression spring is installed. The upper part of the mounting plate has a second mounting hole, which is perpendicular to the first mounting hole. A cylindrical pin is installed in the first mounting hole.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the glass rod to be ground is placed in the placement groove with the protrusion facing upwards. After the glass rod is placed, the side of the glass rod is pressed tightly with the side guard. Soft silicone is attached to the part of the side guard that contacts the glass rod to prevent the glass rod from breaking due to excessive pressure, and it is compatible with glass rods of a certain diameter range. After the side is pressed, the end face guard is used to press the end face of the glass rod to prevent it from moving back and forth during the grinding process. After fixing, the grinding table is placed on the base and fixed to prevent it from moving during the grinding process. The grinding rod is then used to grind the glass rod along the axial direction to grind the protrusion on the side of the glass rod flat or reduce it, thereby improving the product yield during the rough grinding of the grinding wheel. This effectively solves the problems of low efficiency, high difficulty and easy breakage during the rough grinding of small rod-shaped glass by hand. Attached Figure Description

[0027] A small rod-shaped glass side polishing device includes a base, on which a polishing table is provided. A placement groove is provided on the upper surface of the polishing table along the length direction of the polishing table. A glass rod to be polished is placed in the placement groove. End face guards for pressing the end face of the glass rod to be polished are provided on the front and rear end faces of the polishing table. Side guards for pressing the side of the glass rod to be polished are provided on both sides of the placement groove on the upper surface of the polishing table. A polishing rod is placed in the gap between the two side guards.

[0028] Specifically, the side guard edge near the glass rod to be polished is covered with soft silicone.

[0029] Specifically, the placement groove is provided in two sets.

[0030] Specifically, the polishing rod includes a polishing part and a handheld part connected above the polishing part.

[0031] Specifically, the polishing table is detachably mounted on the base.

[0032] Specifically, the end face retainer includes a mounting plate, which is mounted on a grinding table by screws. The mounting plate has a first mounting hole, in which a compression spring is installed. The upper part of the mounting plate has a second mounting hole, which is perpendicular to the first mounting hole. A cylindrical pin is installed in the first mounting hole.

[0033] This embodiment primarily addresses the protrusions generated during the wire cutting of rod-shaped glass with a diameter less than 3mm. The glass rod to be ground is placed in the placement groove, with the protrusion facing upwards. Multiple glass rods can be placed at once; the specific number depends on the length of the glass rod and the size of the grinding table. The size of the placement groove is determined by the diameter of the glass rod. After the glass rod is placed, a side guard is used to press it firmly against the side of the glass rod. Soft silicone is applied to the part of the side guard that contacts the glass rod to prevent excessive pressure from breaking the glass rod and to accommodate glass rods of a certain diameter range. Specifically, the side guard is fixed to the grinding table by passing a screw through a slotted hole in the side guard. During adjustment, the screw in the slotted hole is loosened, and the side guard is manually pressed against the glass rod. After pressing, the screw is tightened. After side clamping, use the end face guard to press the end face of the glass rod to be ground firmly to prevent it from moving back and forth during grinding. Specifically, the end face guard includes a mounting plate, a compression spring, and a cylindrical pin. The mounting plate is installed on the grinding table with screws, and the compression spring inside the mounting plate presses the cylindrical pin firmly, ensuring that it does not move back and forth during grinding. To adjust, move the cylindrical pin back and forth until its end face is flush with the end face of the glass rod to be ground. After fixing, place the grinding table on the base and secure it to prevent movement during grinding. Use the grinding rod to grind the glass rod along the axial direction, smoothing or reducing the protrusions on the side of the glass rod to improve the product yield during rough grinding. This effectively solves the problems of low efficiency, high difficulty, and easy breakage during rough grinding of small rod-shaped glass using traditional manual grinding.

[0034] As a preferred option, the action of the grinding rod, side guard, and end guard can all be replaced by a motor, cylinder, or other drive mechanism to improve the degree of automation.

[0035] The above description constitutes an embodiment of this utility model. The foregoing descriptions are preferred embodiments of this utility model. Unless there is a clear contradiction between the preferred embodiments or a premise based on a particular preferred embodiment, the preferred embodiments can be arbitrarily combined and used. The embodiments and specific parameters described are merely for clearly illustrating the verification process of the utility model and are not intended to limit the patent protection scope of this utility model.
