Description

Technical Field

[0001] The utility model relates to the technical field of automatic grinding equipment, in particular to an automatic dressing device for a grinding wheel on automatic grinding equipment. Background Art

[0002] Currently, automated spherical grinding equipment, as equipment for processing sapphire surfaces, typically uses diamond grinding wheels to process sapphire. Due to the high hardness of sapphire, the grinding wheel is constantly worn during processing. The worn grinding wheel is not sharp, resulting in insufficient cutting force and poor grinding accuracy. The grinding wheel must be dressed with an oilstone to keep it sharp. Manual dressing of the grinding wheel consumes labor and is difficult to guarantee efficiency and safety. To address this problem, there is an automatic grinding wheel dressing mechanism on the market. However, when dressing small-diameter grinding wheels, it has certain defects. Specifically, when the grinding wheel size (i.e., diameter) is smaller than the width of the oilstone, because the oilstone can only move in the XZ direction and cannot move relative to the grinding wheel in the width direction (Y direction), the oilstone cannot guarantee the complete consumption of the oilstone during the dressing process, resulting in significant waste.

DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and implementation methods.

[0023] It also includes: an X-direction mounting plate 304, two X-direction slide rails 305 parallel to each other and provided on the back of the X-direction mounting plate, two X-direction sliders 306 movably provided on the two X-direction slide rails and fixedly connected to the upper end of the X-direction vertical plate, an X-direction motor mounting vertical plate 307 whose lower end is fixedly connected to the back of the upper end of the X-direction vertical plate, an X-direction motor mounting plate 308 vertically connected to the upper end of the X-direction motor mounting vertical plate, an X-direction motor 309 provided on the X-direction motor mounting plate, an X-direction gear 310 provided on the output end of the X-direction motor and located below the X-direction motor mounting plate, an X-direction rack 311 provided on the upper surface of the X-direction mounting plate 304 and meshing with the X-direction gear, two X-direction stoppers 312 provided on the upper surface of the X-direction mounting plate 304 and respectively located at the ends of the X-direction racks abutting each other, and two X-direction stoppers 313 provided on one end surface of the X-direction mounting plate and respectively located on one side of the two X-direction sliders.

[0024] The Z-direction trimming assembly 40 includes: a Z-direction slider plate 401 fixedly mounted on the front surface of the X-direction mounting plate 304, a Z-direction slide rail 402, two Z-direction sliders 403 arranged up and down and movably connected to the Z-direction slide rail and fixedly connected to the front surface of the Z-direction slider plate, a Z-direction support plate 404 with one end vertically connected to the front surface of the X-direction mounting plate 304, a Z-direction motor plate 405 vertically connected to the other end of the Z-direction support plate, a Z-direction motor 406 arranged on the Z-direction motor plate, a Z-direction rack 407 fixedly mounted on the front surface of the Z-direction slide rail, and a Z-direction gear 408 arranged on the output end of the Z-direction motor and meshing with the Z-direction rack.

[0025] It also includes: a transverse U-shaped pressure block 409 clamped at the lower end of the Z-axis slide rail, two oilstone fixing plates 410 parallel to each other and fixedly connected to the transverse U-shaped pressure blocks, a front fixing plate 411 perpendicularly arranged at the front end of the oilstone fixing plate located on the right side, a transverse connecting side plate 412 with one end perpendicularly connected to the outer side surface of the oilstone fixing plate located on the right side, and an L-shaped protective plate 413 arranged at the other end of the transverse connecting side plate and located in front of the front fixing plate 411; the two oilstone fixing plates 410 and the front fixing plate 411 are enclosed in a frame, and the upper end of the oilstone 50 is fixed in the frame; the transverse connecting side plate 412 and the L-shaped protective plate 413 are connected by an integral molding manner.

[0026] After the Y-direction motor 205 is started, it drives the Y-direction driving gear 206 to rotate. Since the trimming bracket 10 is fixed, the Y-direction rack 207 is fixed.

After the Z-direction motor 406 is started, it drives the Z-direction gear 408 to rotate, drives the Z-direction rack 407 to reciprocate in the Z-direction, and then drives the Z-direction slide 402 connected to the Z-direction rack and the oilstone 50 connected to the Z-direction slide to reciprocate in the Z-direction. That is, the oilstone 50 can move in the three directions of X, Y, and Z under the drive of the Y-direction dressing assembly 20, the X-direction dressing assembly 30, and the Z-direction dressing assembly 40. When used to dress a small grinding wheel, that is, when the diameter of the grinding wheel is much smaller than the width of the oilstone 50, the oilstone can also be fully utilized in the dressing process, and there will be no remaining oilstone that is unsuitable for continued use, thereby causing waste of oilstone.
