Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding machine tool technology, specifically to an open-type mist suction device for large cylindrical grinding machines. Background Technology
[0002] Grinding fluid plays a crucial role in grinding processes. During grinding, the grinding wheel and workpiece generate a large amount of heat, which can lead to localized high temperatures on the workpiece, causing material deformation, burning, or changes in hardness. Grinding fluid absorbs and removes heat through flushing, preventing thermal damage to the workpiece, preventing the grinding wheel from losing its bonding strength due to overheating, extending its service life, and flushing away metal particles and abrasive grains detached from the grinding wheel, preventing debris accumulation that could scratch the workpiece or clog the grinding wheel's pores.
[0003] However, splattering grinding fluid can contaminate the workshop. For workshops with clean production requirements, a fully enclosed protective cover is needed to prevent splattering and contamination. However, due to the enormous size of large cylindrical grinding machines, the required fully enclosed protective cover must also be very large, resulting in high manufacturing costs. Moreover, after a period of use, the fully enclosed protective cover must be maintained, requiring manual cleaning of the grinding fluid adhering to its inner wall. This maintenance and cleaning process is tedious and labor-intensive. Summary of the Invention
[0004] In view of the shortcomings of existing enclosed protective covers for large cylindrical grinding machines, such as large size, difficult maintenance, and high cost, this utility model provides an open-type mist suction device for large cylindrical grinding machines, which can reduce costs.
[0005] An open-type mist suction device for a large cylindrical grinding machine is characterized in that: it includes a mist suction device bracket, a mist suction device is installed at the top of the mist suction device bracket, an arc-shaped transition bracket is connected to the bottom inlet of the mist suction device, a spring hose is connected to the transition bracket, the spring hose is connected to a horn-shaped suction hood, the suction hood is installed on a grinding frame bracket, the grinding frame bracket is installed on the grinding frame of the cylindrical grinding machine, and the opening of the suction hood faces the contact point between the grinding wheel and the workpiece of the cylindrical grinding machine.
[0006] Its further features are:
[0007] The grinding frame support includes a lower support and an inverted L-shaped upper support. The upper support is rotatably mounted on the lower support. A cam limiter is installed at the connection between the upper support and the lower support. A tightening screw is installed on the top of the lower support.
[0008] The fogging device has a first drain outlet in the middle and a second drain outlet at the bottom of the transition bracket. The first drain outlet and the second drain outlet are connected to the machine tool water return system.
[0009] With the above-described structure of this invention, the mist extractor draws the grinding fluid mist generated during workpiece grinding from the horn-shaped suction hood into the mist extractor for processing via a spring hose. This achieves open-type mist extraction, resulting in a simple structure, less material usage, and reduced production costs. The first drain port on the mist extractor and the second drain port on the transition bracket allow the grinding fluid to be discharged into the machine tool's return water system after treatment, enabling cleaning and recycling of the grinding fluid. This simplifies maintenance and further reduces costs by conserving grinding fluid. Attached Figure Description

[0011] Figure 2 This is a schematic diagram of the structure of the suction hood and grinding frame support of this utility model. Detailed Implementation
[0012] An open-type mist suction device for a large cylindrical grinding machine 7 includes a mist suction bracket 1, a mist suction device 2 mounted on the top of the mist suction bracket 1, an arc-shaped transition bracket 3 connected to the bottom inlet of the mist suction device 2, a spring hose 4 connected to the transition bracket 3, a horn-shaped suction hood 5 connected to the spring hose 4, and a suction hood 5 mounted on a grinding frame 8 bracket 6. The grinding frame 8 bracket 6 is mounted on the grinding frame 8 of the cylindrical grinding machine 7, and the opening of the suction hood 5 faces the contact point between the grinding wheel 9 and the workpiece 10 of the cylindrical grinding machine 7.
[0013] When the grinding machine is working, the grinding head 8 and the grinding wheel 9 will reciprocate back and forth to process different positions of the workpiece 10. The suction hood 5 and the support 6 of the grinding head 8 move together with the grinding head 8 to ensure that the suction hood 5 is always aligned with the contact point between the grinding wheel 9 and the workpiece 10. The spring hose 4 can deform and move with the movement of the suction hood 5 to prevent the pipes of the mist suction device from obstructing the movement of the grinding machine.
[0014] The grinding head 8 support 6 includes a lower support 14 and an inverted L-shaped upper support 13, with the upper support 13 rotatably mounted on the lower support 14. A cam limiter 15 is installed at the connection between the upper support 13 and the lower support 14 to limit the upper support 13 during normal operation of the grinding machine and prevent it from swinging.
[0015] A clamping screw 16 is installed on the top of the lower support 14. When the grinding machine needs to change the grinding wheel 9 or the workpiece 10 to be processed, the cam limiter 15 is opened, and the upper support 13 can be rotated to a suitable position. Then, the clamping screw 16 is tightened to fix the upper support 13, preventing the upper support 13 and the suction hood 5 from obstructing the change of the grinding wheel 9 or workpiece 10. After the change is completed, the clamping screw 16 is loosened, the upper support 13 is reset, the cam limiter 15 is closed, and the grinding machine and the mist suction device can continue to operate.
[0016] The mist extractor 2 has a first drain port 11 in the middle, and the transition bracket 3 has a second drain port 12 at the bottom. The first drain port 11 and the second drain port 12 are connected to the machine tool return water system (not shown in the diagram). The grinding fluid sucked in by the mist extractor 2 is treated by the mist extractor 2 and then discharged into the machine tool return water system through the first drain port 11 and the second drain port 12. This process cleans and recycles the grinding fluid, saving on the cost of the grinding fluid and simplifying the cleaning and maintenance process.
