Description

Technical Field

[0001] The utility model relates to the technical field of optical glass grinding equipment, in particular to a suspended optical glass processing fluid grinder. Background Art

[0002] Glass products refer to daily necessities and industrial products processed mainly with glass as the raw material. Glass products are widely used in fields such as construction, daily use, medical treatment, chemistry, household, electronics, instruments, nuclear engineering, etc.; Glass is a relatively transparent solid substance, a silicate non-metallic material that forms a continuous network structure during melting and gradually increases in viscosity and hardens without crystallization during the cooling process. In order to obtain the high performance of various precision instruments and equipment, the surface processing accuracy of glass lenses is getting higher and higher, and some even require a processing accuracy of up to the micron level or higher and a surface processing quality without damage. Ultra-precision polishing is currently the main final processing method. The material removal amount during the polishing process is very small, generally less than a few microns. However, during the polishing process, when applied to some glass surfaces with a relatively thin thickness, because most existing polishing tool heads are made of diamond, under the direct action of the polishing tool head, with hard contact, the polishing and grinding resistance is large, and the polished glass is prone to breakage, resulting in a low yield rate. Therefore, improvement is needed. Summary of the Utility Model

The connecting member includes a sleeve, a sliding sleeve and a spline shaft. The sliding sleeve and the spline shaft are installed in the sleeve. The output end of the driving member extends into the sleeve and is connected to the upper end of the sliding sleeve to drive the sliding sleeve to move up and down. The lower end of the sliding sleeve is movably connected to the upper end of the fluid cylinder through a rotary joint. The fluid cylinder penetrates the spline shaft. Both ends of the spline shaft are movably connected to the inner wall of the sleeve through bearings. A driven wheel is sleeved outside the spline shaft. The output end of the motor is provided with a driving wheel. The driving wheel drives the driven wheel to rotate through a transmission member. The grinding head is installed at the lower end of the fluid cylinder and is communicated with it.

The terms used in the description of this utility model herein are for the purpose of describing specific embodiments only and are not intended to limit this utility model. The term "and / or" as used herein includes any and all combinations of one or more of the related listed items.

[0020] As Figures 1 - 2As shown in the figure, a floating optical glass processing fluid grinding machine includes a motor 1, a driving member 2, a connecting member 3, a rotary joint 4, a fluid cylinder 5 and a grinding head 6. The connecting member 3 includes a sleeve 31, a sliding sleeve 32 and a spline shaft 33. The sliding sleeve 32 and the spline shaft 33 are installed in the sleeve 31. The output end of the driving member 2 extends into the sleeve 31 and is connected to the upper end of the sliding sleeve 32 to drive the sliding sleeve 32 to move up and down. The lower end of the sliding sleeve 32 is movably connected to the upper end of the fluid cylinder 5 through the rotary joint 4. The fluid cylinder 5 penetrates through the spline shaft 33. Both ends of the spline shaft 33 are movably connected to the inner wall of the sleeve 31 through bearings 331. A driven wheel 332 is sleeved outside the spline shaft 33. The output end of the motor 1 is provided with a driving wheel 11. The driving wheel 11 drives the driven wheel 332 to rotate through a transmission member 7. The grinding head 6 is installed at the lower end of the fluid cylinder 5 and is communicated with it. Specifically, in this embodiment, the motor 1 is used to drive the grinding head 6 to rotate, while the driving member 2 is used to drive the grinding head 6 to rotate and lift at the same time, adjusting the distance between the port of the grinding head 6 and the surface of the workpiece. During processing, the distance between the grinding head 6 and the surface of the workpiece can be set to 1 mm. It can be known that during processing, an external pressurizing device transports grinding fluid to the grinding head 6 through the rotary joint 4 and the fluid cylinder 5. The grinding fluid is gathered and restricted by the cooperation of the grinding head 6 and the surface of the workpiece to prevent overflow. When the grinding head 6 rotates, it drives the grinding fluid to rotate, thus achieving the purpose of performing a floating processing operation on the surface of the workpiece using a fluid grinding fluid. The surface of the glass workpiece is polished using a high-pressure and high-speed rotating fluid grinding fluid, without using a solid diamond cutter head, improving the machining accuracy of the workpiece surface and effectively ensuring the yield rate of the thin plate workpiece during processing. Further, it should be noted that during the processing process, the external pressurizing device inputs pressurized grinding fluid through the rotary joint 4. In order to enable the grinding head 6 to lift and adjust the height while rotating, we install the fluid cylinder 5 in the sleeve 31 through the spline shaft 33. A vertical chute is provided on the inner wall of the spline shaft 33 for cooperating with the outer wall of the fluid cylinder 5. A driven wheel 332 is sleeved outside the spline shaft 33, and both ends are movably connected to the inner wall of the sleeve 31 through bearings 331. When the spline shaft 33 is driven to rotate by the driven wheel 332, it can drive the fluid cylinder 5 to rotate synchronously. The upper end of the fluid cylinder 5 is connected to the sliding sleeve 32 through the rotary joint 4, so that the fluid cylinder 5 can rotate while the sliding sleeve 32 remains stationary. It can be understood that the grinding fluid input from the outside is also input into the fluid cylinder 5 through the rotary joint 4. At the same time, when the sliding sleeve 32 is displaced by the driving member 2, it can drive the fluid cylinder 5 through the rotary joint 4 to move up and down along the vertical groove on the inner wall of the spline shaft 33, thereby adjusting the height of the grinding head 6 from the surface of the workpiece and realizing floating grinding.

[0021] As Figure 2As shown, the sliding sleeve 32 is hollow and internally provided with a buffer spring 321. The upper end of the rotary joint 4 abuts against the buffer spring 321, preventing the sliding sleeve 32 from directly transmitting the force rigidly to the output rod of the driving member 2 under the influence of the vibration of the fluid cylinder 5 during the floating grinding process, which is likely to damage the output rod of the driving member 2.

[0022] As Figure 2 shown, the transmission member 3 is a synchronous belt. When the driving pulley 11 rotates, the driven pulley 332 is driven to rotate through the synchronous belt, enabling the fluid cylinder 5 to freely rotate within the sliding sleeve 32. Synchronous belt transmission has good rotational speed consistency, facilitating directly regulating the rotational speed of the motor 1 to adjust the rotational speed of the grinding head 6 and achieve high-precision machining.

[0023] As Figure 2 shown, the grinding head 6 is connected to the lower end of the fluid cylinder 5 through a swivel joint 61, facilitating the disassembly and assembly of the grinding head 6. The connection between the grinding head 6 and the fluid cylinder 5 has stronger sealing performance and prevents leakage.

[0024] As Figure 3 shown, the water spraying surface of the grinding head 6 is concave towards the fluid cylinder 5. Specifically, when high-pressure grinding fluid is ejected from the grinding head 6, to prevent the grinding fluid from overflowing from the gaps between the edge of the grinding head 6 and the workpiece surface, the grinding head 6 is designed in an upwardly concave shape, which serves to gather the grinding fluid. When the grinding head 6 rotates and displaces on the workpiece surface following the main equipment, it avoids a large amount of grinding fluid from overflowing, reducing the consumption of grinding fluid and the grinding cost.

[0025] As Figure 2 shown, copper sleeves 333 are installed at both ends of the spline shaft 33, and the bearing 331 is sleeved outside the copper sleeves 333. The copper sleeves 333 are used to protect both ends of the spline shaft 33 from wear and damage.

[0026] Specifically, in this embodiment, the driving member 2 is a cylinder, and a thin-type low-friction cylinder can be used. In other embodiments, an electric push cylinder or a lead screw can also be used, as long as it can drive the sliding sleeve 32 to displace normally up and down.

[0027] As Figure 2 shown, a belt pulley pressing plate 12 is further provided at the output end of the motor 1. The belt pulley pressing plate 12 is located below the driving pulley 11 and is used to limit the driving pulley 11 to prevent it from wobbling during rotation.

[0028] As Figures 1 - 2 shown, the motor 1 is covered with a connection seat 13 for installing and protecting the motor 1.

[0029] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
