Description

Technical Field

[0001] This utility model belongs to the field of grinding equipment, and specifically relates to a secondary treatment device for grinding machine cutting fluid. Background Technology

[0002] During the machining process of bearings, the bearing temperature will rise, causing the bearing's machining dimensions to exceed tolerances. To reduce the bearing temperature during machining, cutting fluid is usually used for cooling. Cutting fluid can carry away the heat from the bearing surface during the machining process, keeping the bearing temperature at a normal level throughout the machining process.

[0003] However, during the contact process between the cutting fluid and the bearing workpiece, the cutting fluid not only carries away the heat of the workpiece, but also carries away the metal chips generated during the cutting process. In the prior art, a liquid storage tank is provided at the lower end of the machine tool. The liquid storage tank is used to collect the cutting fluid and allow the metal chips in the cutting fluid to settle at the lower end of the liquid storage tank. Then, a water pump is used to pump the cutting fluid out of the liquid storage tank and back into the cooling pipe to cool the workpiece.

[0004] Cooling tanks are suitable for lathes and milling machines, but in grinding machines, where the machining precision is high and the metal chips are small and settle slowly, a lot of metal chips will re-enter the cooling pipes when using a cooling tank. If the coolant carries a lot of metal chips, it will accelerate the wear of the machine tool and reduce the service life of the cutting fluid, resulting in waste. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model provides a secondary treatment device for grinding machine cutting fluid. The device is installed at the rear end of the fluid storage tank and utilizes the magnetic attraction principle to effectively reduce the content of metal debris in the cutting fluid. It is suitable for machining iron and steel bearing workpieces on grinding machines.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a secondary treatment device for grinding machine cutting fluid, comprising a water pipe, a filter box, a filter plate, and a magnet. The filter box has a filter plate in its middle section, dividing the interior of the filter box into an upper clear water tank and a lower sedimentation tank. The sedimentation tank has an inlet pipe on its side wall, connected to one end of a water pipe, and the other end of the water pipe is connected to the outlet pipe of the machine tool's fluid storage tank. The sedimentation tank has a slag discharge pipe on its side wall. A water pump is installed on the upper surface of the filter box, with the pump's inlet located inside the clear water tank. The magnet is located on the lower surface of the filter box and is in contact with the lower surface of the filter box.

[0007] The filter box is a round tube with a closed lower end and a flange at the upper opening. Multiple threaded holes are evenly distributed on the upper surface of the flange.

[0008] A step is provided at the junction of the clear water tank and the sedimentation tank, and the step is adapted to the filter plate.

[0009] The filter plate is a flat plate with multiple filter holes evenly distributed on its upper surface.

[0010] The water outlet pipe is located on the side wall of the storage tank, and the horizontal height of the water outlet pipe is higher than the height of the water pump inlet.

[0011] The water pump is mounted on the upper end face of the flange and fixed with bolts.

[0012] The slag discharge pipe is located at the lower end of the side wall of the settling tank, and a valve is provided at the end of the slag discharge pipe near the settling tank.

[0013] The magnet is an electromagnet with adjustable magnetic force.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a secondary treatment device for grinding machine cutting fluid. The device is installed at the rear end of the storage tank and uses the magnetic attraction principle to quickly adsorb small metal debris in the cutting fluid to the bottom of the filter box, thereby reducing the metal debris content in the cutting fluid, thus improving the service life of the cutting fluid and reducing machine tool wear.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] The following is in conjunction with the appendix Figure 1-4The specific embodiments of this utility model are further described in detail below: A secondary treatment device for grinding machine cutting fluid includes a water pipe 2, a filter box 3, a filter plate 4, and a magnet 7. The filter box 3 is a circular tube, with its lower end closed and a flange 32 provided at the upper opening. Multiple threaded holes 34 are evenly distributed on the upper surface of the flange 32. The water pump 5 is installed on the upper surface of the flange 32 and fixed by bolts 6. In this embodiment, the filter box 3 is a circular tube. In actual use, The shape of the filter box 3 can be changed according to specific needs, such as a square box. The internal structure of the filter box 3 only needs to be divided into a clear water tank and a sedimentation tank. The filter box 3 is provided with a filter plate 4 in the middle, which divides the interior of the filter box 3 into an upper clear water tank and a lower sedimentation tank. The sedimentation tank is provided with a water inlet pipe 31 on its side wall. The water inlet pipe 31 is connected to one end of the water pipe 2, and the other end of the water pipe 2 is connected to the water outlet pipe 11 of the machine tool storage tank 1. The water outlet pipe 11 is located on the side wall of the storage tank 1, and the horizontal height of the water outlet pipe 11 is higher than the height of the water pump 5 inlet. The horizontal height of the water outlet pipe 11 is higher than the height of the water pump 5 inlet, which can ensure that the water pump 5 inlet is always located at the lower end of the cutting fluid, thereby ensuring the normal operation of the water pump 5. A slag discharge pipe 35 is provided on the side wall of the sedimentation tank. The slag discharge pipe 35 is located at the lower end of the side wall of the sedimentation tank, and a valve is provided near the end of the slag discharge pipe 35. The slag discharge pipe 35 is used to clean metal debris from the bottom of the sedimentation tank. A water pump 5 is installed on the upper surface of the filter box 3, and the inlet of the water pump 5 is located in the clear water tank of the filter box 3. A step 33 is provided at the junction of the clear water tank and the sedimentation tank. The step 33 is adapted to the filter plate 4. The function of the step 33 is to position the filter plate 4 and prevent it from moving. The filter plate 4 is a flat plate, and multiple filter holes 41 are evenly distributed on the upper surface of the filter plate 4. The size and shape of the filter plate 4 are adapted to the shape of the upper end of the step 33. 1. The cutting fluid can flow from the sedimentation tank into the clean water tank. The filter hole 41 can slow down the flow rate of the cutting fluid, making the cutting fluid in the sedimentation tank more gentle, thereby improving the adsorption efficiency of the magnet 7. The magnet 7 is an electromagnet with adjustable magnetic force. The magnet 7 is located on the lower end face of the filter box 3 and is in contact with the lower end face of the filter box 3. In specific implementation, this device is used in the grinding process of bearing workpieces. The bearing material is steel, and the metal chips from the bearing processing can be adsorbed by the magnet 7. If this device is used in the processing of other workpieces, it is necessary to ensure that the workpiece material is iron or steel and can be adsorbed by the magnet 7. This device is not suitable for the processing of other materials, such as copper and aluminum materials.

[0022] The usage process of this utility model is as follows: Before use, assemble the device and install it on one side of the liquid storage tank 1. During installation, ensure that the horizontal height of the water outlet pipe 11 is higher than the water inlet height of the water pump 5. Start the machine tool. During the machining process, the cutting fluid cools the bearing workpiece. During the cooling process, the cutting fluid first flows into the liquid storage tank 1 for preliminary sedimentation. After sedimentation, the cutting fluid flows out from the water outlet pipe 11 at the top of the liquid storage tank 1 and into the sedimentation tank at the bottom of the filter tank 3. At this time, the fine metal debris mixed in the cutting fluid is adsorbed at the bottom of the sedimentation tank under the action of the magnet 7. After treatment, the cutting fluid flows from the sedimentation tank into the clear water tank after passing through the filter plate 4. Finally, it enters the cold zone pipeline again through the water pump 5 to cool the workpiece. This cycle is repeated. After a period of use, turn off the power of the magnet 7 and open the valve of the slag outlet pipe 35 to clean out the metal debris in the sedimentation tank for long-term use.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
