Description

Technical Field

[0001] The utility model relates to the field of grinding machine tools, in particular to a special inclined cylinder direct-push end face measuring instrument for numerically controlled external cylindrical grinding. Background Art

[0002] With the development of grinding technology, traditional horizontal CNC external cylindrical grinding machines also need to be equipped with end face gauges to detect the grinding accuracy of the outer circle and end faces of cylindrical workpieces (solid workpieces, with the head and tailstock tips unique to the external cylindrical grinding machine supporting the cylindrical solid workpiece at both ends). However, after the end face gauge on the horizontal CNC external cylindrical grinding machine is fixedly installed in the existing technical solution, the entire structure cannot be adjusted up and down or left and right. This means that the probe of the end face gauge cannot be placed in different positions, which in turn makes the end face gauge incapable of simultaneously detecting different workpieces. Utility Model Content

[0003] The embodiment of the present application provides a dedicated inclined cylinder direct-push end face measuring instrument for CNC external cylindrical grinding, thereby solving the technical problem in the existing technical solution that after the end face measuring instrument on the horizontal CNC external cylindrical grinding mill is fixedly installed, the entire structure cannot be adjusted up and down or left and right, which makes it impossible for the probe of the end face measuring instrument to be in different positions, and thus makes the end face measuring instrument unable to be used for the detection of different workpieces at the same time.

[0004] The technical solutions adopted in the embodiments of this application are as follows:

[0005] A special inclined cylinder direct-push end face measuring instrument for CNC external cylindrical grinding, comprising a grinding wheel frame box, a rotating base, a mounting plate, a rotating shaft, a driving device, an end face measuring instrument, a connecting bracket, a slide rail and a slider; the bottom plate and the vertical plate of the rotating base are both provided with arc grooves; the bottom plate of the rotating base is mounted on the top of the grinding wheel frame box by fixing bolts; the bottom end of the mounting plate and the vertical plate of the rotating base are connected by the rotating shaft; the mounting plate is locked to the vertical plate of the rotating base by connecting bolts; the driving device and the slider are both mounted on the top of the mounting plate; the slide rail and the slider are slidably connected; the driving end of the driving device and one end of the slide rail are both connected to the connecting bracket; the end face measuring instrument is mounted on the connecting bracket; and the end of the end face measuring instrument is equipped with an end face measuring instrument probe.

[0006] A further technical solution is: the driving device is a cylinder.

[0007] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0008] 1. Thanks to the grinding wheel housing, rotating base, mounting plate, rotating shaft, drive unit, end face gauge, connecting bracket, slide rail, and slider, the entire structure can be adjusted up and down and left and right, allowing the end face gauge probe to be positioned in different positions to accommodate different workpiece inspections and enriching process diversity. By extending or retracting the drive unit's piston rod (retracting during grinding, extending during inspection), interference between the top end face gauge probe and the workpiece during the front and rear grinding wheel feed operations during cylindrical grinding is avoided. The extension or retraction of the drive unit's piston rod is pulled by the slider and slide rail, ensuring accurate movement. Because the slider and slide rail (in a straight line) are arranged left and right with the drive unit and end face gauge (in a straight line), the overall structure is subjected to relatively uniform force. At the same time, because the drive unit and end face gauge are on the same side, electrical wiring is more convenient, standardized, and aesthetically pleasing. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The embodiment of the present application provides a dedicated inclined cylinder direct-push end face measuring instrument for CNC external cylindrical grinding, thereby solving the technical problem in the existing technical solution that after the end face measuring instrument on the horizontal CNC external cylindrical grinding mill is fixedly installed, the entire structure cannot be adjusted up and down or left and right, which makes it impossible for the probe of the end face measuring instrument to be in different positions, and thus makes the end face measuring instrument unable to be used for the detection of different workpieces at the same time.

[0014] The technical solution in the embodiments of the present application is to solve the above problems, and the overall idea is as follows:

[0015] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0016] A special inclined cylinder direct push end face measuring instrument for CNC external cylindrical grinding, such as Figure 1 、 Figure 2 as well as Figure 3 As shown, it includes a grinding wheel frame box 1, a rotating base 2, a mounting plate 3, a rotating shaft 4, a driving device 5, an end face gauge 6, a connecting bracket 7, a slide rail 8 and a slider 9. Arc grooves are provided on the bottom plate and the vertical plate of the rotating base 2. The bottom plate of the rotating base 2 is mounted on the top of the grinding wheel frame box 1 by fixing bolts 21. The bottom end of the mounting plate 3 and the vertical plate of the rotating base 2 are connected by the rotating shaft 4. The mounting plate 3 is locked to the vertical plate of the rotating base 2 by connecting bolts 31. The driving device 5 and the slider 9 are both mounted on the top of the mounting plate 3. The slide rail 8 and the slider 9 are slidably connected. The driving end of the driving device 5 and one end of the slide rail 8 are both connected to the connecting bracket 7. The end face gauge 6 is mounted on the connecting bracket 7. An end face gauge probe 61 is installed at the end of the end face gauge 6.

[0017] The driving device 5 is a cylinder.

[0018] The entire structure is fixed to the top of the grinding wheel housing 1 via a rotating base 2. The bottom plate of the rotating base 2 features an arcuate groove, allowing for fine-tuning of the relative position of the sleeve structure left and right. The vertical plates of the rotating base 2 also feature an arcuate groove, allowing for fine-tuning of the relative position of the sleeve structure up and down. The lugs of the mounting plate 3 are connected to the vertical plates of the rotating base 2 via a rotating shaft 4. Once the mounting plate 3 is rotated to the desired angle, it can be locked using connecting bolts 31. A slider 9 is fixed to the top of the mounting plate 3, with a sliding connection between the slide rail 8 and the slider 9, allowing for reciprocating movement. The extension and retraction of the piston rod of the drive unit 5 provides power to the slide rail 8. A connecting bracket 7 is mounted on the slide rail 8 and fixed to its end. One end of the connecting bracket 7 is fixedly connected to the end gauge 6 (which is secured within the inner hole of the connecting bracket 7 via a flange connection). The other end of the connecting bracket 7 is threadedly connected to the piston rod of the drive unit 5. The drive unit 5 is fixed to the mounting plate 3 via its own lugs. The mounting surface of the mounting plate 3 is provided with a limited backing surface, which positions the ear seat of the driving device 5 on one side and the slider 9 on the other side to prevent it from moving left and right.

[0019] Thanks to the arrangement of the grinding wheel housing 1, rotating base 2, mounting plate 3, rotating shaft 4, drive unit 5, end gauge 6, connecting bracket 7, slide rail 8, and slider 9, the entire structure can be adjusted vertically and horizontally, allowing the probe of the end gauge 6 to be positioned differently to accommodate different workpiece inspections and enhance process versatility. By extending or retracting the piston rod of the drive unit 5 (retracting during grinding, extending during inspection), interference between the probe of the end gauge 6 at the top and the workpiece during the front and rear grinding wheel feed operations during cylindrical grinding is avoided. The extension or retraction of the piston rod of the drive unit 5 is guided by the slider 9 and slide rail 8, ensuring precise operation. The alignment of the slider 9 and slide rail 8 (in line with the drive unit 5 and end gauge 6) ensures uniform stress distribution throughout the structure. Furthermore, since the drive unit 5 and end gauge 6 are located on the same side, electrical wiring is more convenient, standardized, and aesthetically pleasing.
