Description

Technical Field

[0001] This utility model relates to the field of cylindrical grinding machine technology, specifically to a grinding wheel dressing device for a cylindrical grinding machine. Background Technology

[0002] In the field of machining, cylindrical grinding machines are the core equipment for achieving high-precision external cylindrical machining of shaft and cylindrical workpieces. As a key grinding component of cylindrical grinding machines, the surface morphology of grinding wheels, such as roundness, flatness, and abrasive sharpness, directly determines the machining accuracy of the workpiece. During long-term use, the dulling and out-of-roundness problems caused by abrasive wear and bond detachment of grinding wheels become increasingly prominent. Special dressing devices are needed to repair the surface of the grinding wheels and restore their grinding performance.

[0003] Traditional grinding wheel dressing devices for external cylindrical grinding machines mostly adopt a single-edge dressing structure, that is, a single diamond pen contacts the grinding wheel surface, and dressing is achieved by combining the rotation of the grinding wheel with the feed motion of the dressing device. However, traditional single-edge dressing requires multiple reciprocating feeds to complete the full repair of the grinding wheel surface, which is inefficient. Therefore, a grinding wheel dressing device for external cylindrical grinding machines is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a grinding wheel dressing device for an external cylindrical grinding machine, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a grinding wheel dressing device for an external cylindrical grinding machine, including a base, a movable groove on the top of the base, a dressing mechanism on the base, the dressing mechanism including a movable seat, a first diamond pen and a second diamond pen, the movable seat being slidably connected to the inner wall of the movable groove, and both the first diamond pen and the second diamond pen being mounted on the movable seat.

[0006] Preferably, the base is provided with a threaded rod, one end of which passes through the outer wall of the base and is rotatably connected to the inner wall of the movable groove, and the movable seat is threadedly connected to the threaded rod, and the other end of the threaded rod is fixedly connected to a knob.

[0007] Preferably, a frame is fixedly connected to the top of the movable base, and the first diamond pen is mounted on the top of the frame.

[0008] Preferably, the movable seat is rotatably connected to a gear via a rotating shaft, the inner wall of the movable groove is provided with teeth, and the teeth are meshed with the gear. The top of the movable seat is provided with a slide, a slide block is slidably connected to the slide, and a rack is provided on the slide block, and the rack is meshed with the gear.

[0009] Preferably, the top of the slide is provided with a mounting plate, and the second diamond pen is mounted on the mounting plate.

[0010] Preferably, the frame is provided with a fixing mechanism, the fixing mechanism includes a frame body connected to the frame, an adjusting bolt is threaded onto the frame body, the adjusting bolt is rotatably connected to an arc-shaped block, the arc surface of the arc-shaped block is provided with an anti-slip pad, and the anti-slip pad is in contact with the outer wall of the second diamond pen.

[0011] Preferably, a baffle is fixedly connected to the outer wall of the frame, and the inner wall of the baffle is slidably connected to the mounting plate.

[0012] The present invention adopts the above technical solution, which can bring the following beneficial effects: 1. This grinding wheel dressing device for an external cylindrical grinding machine achieves synchronous dressing of the grinding wheel through a double-edged collaborative dressing structure of a first diamond pen and a second diamond pen. During operation, the grinding wheel surface first contacts the first diamond pen for preliminary dressing, and then contacts the second diamond pen for fine dressing, thereby improving work efficiency.

[0013] 2. The grinding wheel dressing device for this cylindrical grinding machine, when the threaded rod driven by the knob moves the moving seat along the moving groove, the gear on the moving seat meshes with the teeth on the inner wall of the moving groove, and rotates as the moving seat moves; the rotation of the gear then drives the meshing rack and slide along the slide table, and then drives the second diamond pen to move through the mounting plate, thereby synchronously adjusting the second diamond pen and the first diamond pen, saving adjustment time, improving adjustment accuracy, and thus improving the dressing effect.

[0014] 3. The grinding wheel dressing device of this cylindrical grinding machine, by rotating the adjusting bolt, pushes the arc-shaped block to move towards the second diamond pen until the anti-slip pad is tightly attached to the outer wall of the diamond pen, thereby firmly clamping the diamond pen and avoiding the vibration generated by the high-speed rotation of the grinding wheel during the dressing process, which would cause the diamond pen to shift axially or radially, thereby causing wear on the gears, teeth and racks, and improving the service life of the device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 One embodiment of this utility model is: a grinding wheel dressing device for an external cylindrical grinding machine, including a base 1. The bottom of the base 1 is provided with a mounting groove for mounting the base 1 on the guide rail of the external cylindrical grinding machine, thereby moving the base 1 through the guide rail to dress the grinding wheel of the external cylindrical grinding machine. The top of the base 1 is provided with a moving groove, and the bottom of the inner wall of the moving groove is provided with a drain outlet. By providing a drain outlet, it is convenient to drain wastewater when rinsing the inside of the moving groove. A dressing mechanism 2 is provided on the base 1. A baffle 4 is fixedly connected to the outer wall of the frame 24, and the inner wall of the baffle 4 is slidably connected to the mounting plate 212. The baffle 4 is provided to protect the gear 27, teeth 28 and rack 211, so as to prevent the dust generated during the dressing process from affecting the meshing effect of the gear 27, teeth 28 and rack 211.

[0019] The trimming mechanism 2 includes a movable base 23, a first diamond pen 25, and a second diamond pen 213. The movable base 23 is slidably connected to the inner wall of the movable groove. Both the first diamond pen 25 and the second diamond pen 213 are mounted on the movable base 23. A threaded rod 21 is mounted on the base 1. One end of the threaded rod 21 passes through the outer wall of the base 1 and is rotatably connected to the inner wall of the movable groove. The movable base 23 is threadedly connected to the threaded rod 21. A knob 22 is fixedly connected to the other end of the threaded rod 21. A frame is fixedly connected to the top of the movable base 23. The frame 24 has a first diamond pen 25 mounted on top of it. A gear 27 is rotatably connected to the movable seat 23 via a rotating shaft 26. The inner wall of the movable groove is provided with teeth, which mesh with the gear 27. A slide 29 is provided on the top of the movable seat 23. A slide block 210 is slidably connected to the slide 29. A rack 211 is provided on the slide block 210, which meshes with the gear 27. A mounting plate 212 is provided on the top of the slide block 210. The second diamond pen 213 is mounted on the mounting plate 212.

[0020] Please see Figure 1-5 Based on the above embodiments, in another embodiment of the present invention, a fixing mechanism 3 is provided on the frame 24. The fixing mechanism 3 includes a frame 31, which is connected to the frame 24. An adjusting bolt 32 is threadedly connected to the frame 31. An arc-shaped block 33 is rotatably connected to the adjusting bolt 32. An anti-slip pad 34 is provided on the arc surface of the arc block 33, and the anti-slip pad 34 contacts the outer wall of the second diamond pen 213.

[0021] Working principle: The base 1 is installed on the guide rail of the cylindrical grinding machine. By aligning the first diamond pen 25 and the second diamond pen 213 with the grinding wheel on the cylindrical grinding machine, the screw rod 21 is rotated by turning the knob 22. The rotation of the screw rod 21 drives the moving seat 23 to move, which in turn drives the frame 24 to move, thereby driving the first diamond pen 25 to move. At the same time, the movement of the moving seat 23 drives the gear 27 to move on the teeth 28 through the rotating shaft 26, so that the gear 27 rotates while moving. The rotation of the gear 27 drives the rack 28 to move. 11 moves in the same direction as the movable seat 23, thereby causing the slide 210 to move relative to the movable seat 23. This causes the second diamond pen 213 to move via the mounting plate 212, resulting in a displacement of the second diamond pen 213 relative to the first diamond pen 25. This causes the first diamond pen 25 and the second diamond pen 213 to simultaneously contact the grinding wheel. After the second diamond pen 213 contacts the grinding wheel, the adjusting bolt 32 is rotated, causing the arc-shaped block 33 to move. This squeezes the anti-slip pad 34, locking the second diamond pen 213 in place.

[0022] The grinding wheel is rotated by the external cylindrical grinding machine, and the base 1 is moved by the guide rail. The outer wall of the grinding wheel will first contact the first diamond pen 25 and then the second diamond pen 213 to dress the grinding wheel. The grinding wheel is dressed by the first diamond pen 25 and the second diamond pen 213 at the same time, which improves the dressing efficiency and the dressing effect of the grinding wheel.

[0023] This utility model provides a grinding wheel dressing device for an external cylindrical grinding machine. There are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
