Description

Technical Field

[0001] This utility model relates to the field of grinding machine equipment protection technology, and in particular to a water-blocking device for grinding machines. Background Technology

[0002] Cylindrical grinding is a commonly used machining equipment. The worktable and bed of the grinding machine move left and right through the slide guide rail. When the grinding wheel rotates at high speed, it generates a lot of water vapor. In order to protect the guide rail located near the grinding wheel, a rubber plate is usually installed on the side of the worktable. However, since the worktable and bed need to move relative to each other, there will inevitably be a gap between the rubber plate and the slide.

[0003] Because the grinding wheel rotates at high speed, it breaks up water vapor and mixes it with iron powder and grinding wheel powder. The fine water vapor mixed with this mixture will splash into the guide rail through the gap. The accumulation of iron powder and grinding wheel powder in the water vapor will scratch the guide rail and even block the oil injection hole, eventually leading to insufficient oil in the guide rail. Severe scratches on the guide rail will render the grinding machine unusable. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a water-blocking device for grinding machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A water-blocking device for a grinding machine includes an outer baffle and an inner baffle. The outer baffle and the inner baffle are fixed together on the side of the worktable near the grinding wheel. The inner baffle is a bent spring sheet, including a fixed section for connecting the outer baffle and a bent section that is inclined to one side of the machine bed. The lower end of the bent section is in close contact with the outer side of the machine bed under its own elastic force.

[0007] The vertical height of the outer baffle is not less than twice the vertical height of the inner baffle.

[0008] The lower end of the outer baffle has a horizontal section extending toward one side of the bed.

[0009] The horizontal section is located below the stepped portion of the bed.

[0010] The bending angle of the inner baffle is an obtuse angle.

[0011] The lower end of the bent section is fixed with an edge sealing strip.

[0012] The lower end of the bending section has a secondary bending section, which is arranged parallel to the fixed section.

[0013] A rubber pad is fixed to the side of the secondary bending section facing the bed.

[0014] The outer baffle and the inner baffle are bonded and fixed to the workbench with sealant.

[0015] The inner baffle is made of stainless steel and has a thickness between 0.1 and 0.5 mm.

[0016] This invention has the following beneficial effects: The outer baffle blocks most of the water vapor carried out by the grinding wheel, thereby reducing the impact of water vapor on the inner baffle and preventing the inner baffle from failing. The inner baffle provides secondary blocking for a small portion of water vapor splashed from below the outer baffle. Under its own elasticity, the inner baffle is always in close contact with the bed, thus effectively blocking water vapor, iron powder and grinding wheel dust, and effectively protecting the grinding machine guide rail.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

Therefore, they should not be construed as limitations on this utility model.

[0027] like Figure 1 and Figure 2As shown, this utility model provides a water-blocking device for a grinding machine, including an outer baffle 3 and an inner baffle 4. The outer baffle 3 and the inner baffle 4 are fixed together on the side of the worktable 1 near the grinding wheel 5. The inner baffle 4 is a bent spring sheet, including a fixing section 401 for connecting the outer baffle 3 and a bent section 402 inclined towards the side of the machine bed 2. The lower end of the bent section 402 is in close contact with the outer side of the machine bed 2 under its own elastic force. Specifically, the inner baffle 4 is made of stainless steel with a thickness between 0.1-0.5mm. The thickness used in this solution is 0.4mm. The stainless steel material ensures the durability of the inner baffle 4. The outer baffle 3 is made of 3-5mm thick stainless steel plate. The fixing section 401 of the outer baffle 3 and the spring sheet are connected... The inner baffle 4 is fastened together with rivets or bolts to the outside of the worktable 1. The outer baffle 3 blocks most of the water vapor brought out by the grinding wheel 5, so as to reduce the impact of water vapor on the inner baffle 4 and prevent the inner baffle 4 from failing. In the initial state, the width between the surface of the fixed section 401 and the end face of the bent section 402 of the inner baffle 4 is greater than the distance between the surface of the worktable 1 and the surface of the bed 2, so that the inner baffle 4 after installation has a certain elasticity and always keeps in close contact with the bed 2 under its own elasticity. This provides secondary blocking for a small part of the water vapor splashed from below the outer baffle 3 without hindering the relative movement between the worktable 1 and the bed 2, thereby effectively blocking water vapor, iron powder and grinding wheel 5 powder, and effectively protecting the grinding machine guide rail.

[0028] To ensure the airtightness of the connection between the outer baffle 3 and the inner baffle 4 and to prevent moisture from seeping in, the connection between the outer baffle 3 and the inner baffle 4 and the workbench 1 is fixed with sealant.

[0029] like Figure 2 As shown, the vertical height of the outer baffle 3 is not less than twice the vertical height of the inner baffle 4, so as to have the largest possible area to block most of the water vapor; more preferably, the lower end of the outer baffle 3 has a horizontal section 301 extending towards one side of the bed 2 to block water vapor splashed in the opposite direction.

[0030] To achieve a better blocking effect, the horizontal section 301 is located below the step portion 201 of the bed 2.

[0031] like Figures 2-4 As shown, the bending angle of the inner baffle 4 is an obtuse angle, so that the outer surface of the bending section 402 forms a downward inclined guide surface, so that a small amount of water vapor splashed onto the inner side of the outer baffle 3 will gather into water droplets on the outer side of the water droplet flow channel bed 2 after passing through the surface of the inner baffle 4.

[0032] To prevent the inner baffle 4 from scratching the bed frame 2, in embodiment 1, as follows: Figure 4As shown, the lower end of the inner baffle 4 is fixed with an edge sealing strip 6. The edge sealing strip 6 is a U-shaped rubber sealing strip, which is fixed to the lower end of the inner baffle 4 by adhesive or rivets so that the inner baffle 4 is in soft contact with the bed 2.

[0033] In embodiment 2, the lower end of the inner baffle 4 has a secondary bending section 403, which is arranged parallel to the upper end of the inner baffle 4, such as... Figure 5 As shown in (a), the secondary bending section 403 is a forward bend, increasing the contact area between the lower end of the bending section 402 and the bed frame 2, thereby improving the sealing effect. Similarly, in order to achieve soft contact between the secondary bending section 403 and the bed frame 2, a rubber pad 7 is fixed to the side of the secondary bending section 403 facing the bed frame 2; Figure 5 As shown in (b), the secondary bending segment 403 is a reverse bend, and a U-shaped arc structure is formed between the secondary bending segment 403 and the bending segment 402 after the reverse bend. Figure 5 In section (a), a second elastic structure was added to further improve the tight contact between the inner baffle 4 and the bed 2.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
