Description

Technical Field

[0001] The utility model relates to the field of grinding machine tools, in particular to a flat double-track cylinder direct-push end surface measuring instrument specially used for numerically controlled internal grinding. Background Art

[0002] With the advancement of grinding technology, both single-axis CNC horizontal internal grinding machines and dual-axis CNC compound horizontal internal grinding machines require end-face gauges for real-time internal grinding accuracy monitoring of cylindrical sleeves or disc-type workpieces (hollow workpieces whose outer cylindrical surface is gripped by the jaws of the workpiece spindle chuck). This end-face gauge installation method is unique to CNC internal grinding machines. In existing CNC internal grinding machines, the end-face gauge, once fixed, cannot be adjusted forward or backward. This prevents the gauge's probe from being positioned differently, making it inappropriate for inspecting different workpieces simultaneously. Utility Model Content

[0003] The embodiment of the present application provides a flat double-track cylinder direct-push end face measuring instrument specially designed for CNC internal cylindrical grinding, which solves the technical problem in the existing technical solution that after the end face measuring instrument on the CNC internal cylindrical grinding mill is fixedly installed, the entire structure cannot be adjusted forward and backward, which makes it impossible for the probe of the end face measuring instrument to be in different positions, and thus causes the end face measuring instrument to be unable to be used for different workpiece inspections at the same time.

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

[0005] A flat double-track cylinder direct-push end face measuring instrument specially used for CNC internal cylindrical grinding, comprising a slide plate, a pad seat, an adjustment plate, an internal cylindrical grinding head seat, an internal cylindrical grinding wheel, a grinding wheel rod, an internal cylindrical electric spindle, a mounting plate, a driving device, an L-shaped bracket and an end face measuring instrument; the pad seat is mounted on the slide plate; the adjustment plate is mounted between the internal cylindrical grinding head seat and the pad seat; the internal cylindrical grinding wheel is mounted on the end of the grinding wheel rod; the tail of the grinding wheel rod is threadedly connected to the end face of the internal cylindrical electric spindle; the internal cylindrical electric spindle is clamped inside the internal cylindrical grinding head seat; the mounting plate is mounted on the side of the internal cylindrical grinding head seat; the driving device is mounted on the mounting plate; the L-shaped bracket is arranged on the driving end of the driving device; and the end face measuring instrument is mounted on the end of the L-shaped bracket.

[0006] A further technical solution is: a T-slot is provided on the raising seat; and the adjusting plate is slidably connected to the T-slot.

[0007] A further technical solution is: the driving device is a double-track cylinder.

[0008] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0009] 1. The system utilizes a slide, a spacer, an adjustment plate, an internal grinding head seat, an internal grinding wheel, a grinding wheel rod, an internal electric spindle, a mounting plate, a drive unit, an L-shaped bracket, and an end-face gauge. The T-slot on the top of the spacer allows for wide adjustment of the internal grinding head seat, while the slots on the L-shaped bracket and the drive unit allow for finer adjustment. This allows for the adjustment of the entire system to accommodate a variety of cylindrical and disc-shaped workpieces. Furthermore, the system allows for fore-and-aft position adjustment, allowing the end-face gauge probe to be positioned in different locations to accommodate workpieces of varying thicknesses, thus increasing process versatility. The drive unit is mounted directly on the side of the internal grinding head seat, and its relatively flat design reduces overall installation space, minimizing interference with the grinding wheel rod during reciprocating grinding. A dual-track pneumatic cylinder provides forward and backward movement, ensuring precision during both forward and backward push and retraction movements. The spacer can be mounted anywhere on the slide, either above or below, or forward and backward, allowing the end-face gauge to be positioned in various inspection positions, further increasing process versatility.

[0014] The embodiment of the present application provides a flat double-track cylinder direct-push end face measuring instrument specially designed for CNC internal cylindrical grinding, which solves the technical problem in the existing technical solution that after the end face measuring instrument on the CNC internal cylindrical grinding mill is fixedly installed, the entire structure cannot be adjusted forward and backward, which makes it impossible for the probe of the end face measuring instrument to be in different positions, and thus causes the end face measuring instrument to be unable to be used for different workpiece inspections at the same time.

[0015] The technical solution in the embodiments of the present application is to solve the above problems, and the overall idea is as follows:

[0016] 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.

[0017] A flat double-track cylinder direct-push end face measuring instrument specially designed for CNC internal grinding, such as Figure 1 、 Figure 2 as well as Figure 3 As shown, it includes a slide 1, a pad 2, an adjustment plate 3, an internal grinding head seat 4, an internal grinding wheel 5, a grinding wheel rod 6, an internal electric spindle 7, a mounting plate 8, a drive device 81, an L-shaped bracket 82 and an end face gauge 9. The pad 2 is installed on the slide 1. The adjustment plate 3 is installed between the internal grinding head seat 4 and the pad 2. The internal grinding wheel 5 is installed at the end of the grinding wheel rod 6. The tail of the grinding wheel rod 6 is threadedly connected to the end face of the internal electric spindle 7. The internal electric spindle 7 is clamped inside the internal grinding head seat 4. The mounting plate 8 is installed on the side of the internal grinding head seat 4. The drive device 81 is installed on the mounting plate 8. The L-shaped bracket 82 is set on the driving end of the drive device 81. The end face gauge 9 is installed at the end of the L-shaped bracket 82.

[0018] A T-slot is provided on the raising seat 2. An adjusting plate 3 is slidably connected to the T-slot.

[0019] The driving device 81 is a double-track cylinder (a double-track cylinder has two upper and lower tracks, and a guide in the middle, so that the force is evenly distributed and the movement is stable).

[0020] The entire structure is mounted on a slide 1 that reciprocates forward and backward. A raised seat 2 is fixedly mounted on the top of the slide 1 and is used to adjust the height of the entire end face measuring instrument device. A T-slot is provided on the top of the raised seat 1, which allows the internal grinding head seat 4 to be adjusted forward and backward as a whole. An adjustment plate 3 is mounted between the internal grinding head seat 4 and the raised seat 2 and is used to adjust the height to the center of the workpiece spindle chuck on the left and the clamped workpiece. When the height is equal, the internal grinding wheel 5 can reciprocate back and forth to grind the inner hole of the cylindrical workpiece. The internal grinding wheel 5 is fixedly mounted on the end of the grinding wheel rod 6, the tail of which is threadedly connected to the end face of the internal electric spindle 7. The internal electric spindle 7 is clamped inside the internal grinding head seat 4 and locked with a locking screw on the side. The mounting plate 8 is fixedly mounted on the side of the internal grinding head seat 4 (the side without the locking screw connection seam). The end face measuring instrument 9 is fixedly mounted on the front end face of the L-shaped bracket 82. The L-shaped bracket 82 is provided with a wiring hole 821 to facilitate the exit of the cables from the rear of the end gauge 9. The drive unit 81 is fixedly mounted on the mounting plate 8. The L-shaped bracket 82 is connected to the movable surface of the drive unit 81 via two rows of upper and lower guide slots and can be adjusted forward and backward. The forward and backward movement of the piston rod of the drive unit 81 drives the forward and backward movement of the end gauge 9 (the extension and retraction stroke of the drive unit 81 is fixed and unchanging).

[0021] Due to the arrangement of the slide 1, the raised seat 2, the adjustment plate 3, the internal grinding head seat 4, the internal grinding wheel 5, the grinding wheel rod 6, the internal electric spindle 7, the mounting plate 8, the drive unit 81, the L-shaped bracket 82, and the end face gauge 9, the T-slot provided on the top of the raised seat 2 and the internal grinding head seat 4 can be adjusted to a large extent, while the slot provided on the L-shaped bracket 82 and the drive unit 81 can be adjusted to a small extent, thereby meeting the requirements of different cylindrical and disc-type workpieces. The entire structure can also be adjusted forward and backward, allowing the probe of the end face gauge 9 to be positioned in different positions to accommodate workpieces of varying thicknesses, thus enriching process diversity. The drive unit 81 is directly mounted on the side of the internal grinding head seat 4, and the drive unit 81 itself is relatively flat, which directly compresses the overall installation space, making it less likely to cause interference during the reciprocating grinding of the grinding wheel rod 6. By using a dual-track cylinder for forward and backward movement, precision is guaranteed during forward and backward push or retraction movements. The raising seat 2 can be installed at any upper or lower, front or back position of the slide plate 1, so that the end face measuring instrument 9 can be placed at different detection positions, thereby enriching the process diversity.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0023] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
