Technical Field

[0001] The utility model relates to the technical field of precision machining, in particular to an automatic grinding liquid adding structure. Background Art

[0002] In the field of precision and ultra-precision machining, parts machining mainly adopts the method of small removal and multiple processing to approximate the processing parameters. The grinding fluid made of micro-powder abrasive and related liquid ratio has good practicality when machining workpieces with small removal amount.

[0003] At present, most of them place the workpiece on the grinding disc, and then spray the grinding fluid through the nozzle to remove the workpiece to complete the processing. However, the existing processing method has the following problems:

[0004] Currently, since most nozzles are fixed and not easy to rotate, the workpiece cannot be completely processed during the machining removal process, so that the grinding fluid contacted by the workpiece is not uniform, which reduces the machining effect;

[0005] In view of the above problems, the utility model document proposes an automatic grinding liquid adding structure. Utility Model Content

[0006] The utility model provides an automatic grinding liquid adding structure, which solves the problem in the prior art that most of the nozzles are fixed and not easy to rotate, resulting in the workpiece not being able to be completely processed during the machining removal process, making the grinding liquid that the workpiece contacts as a whole not uniform, thereby reducing the machining effect.

[0007] The utility model provides the following technical solutions:

[0008] A grinding liquid automatic adding structure, comprising:

[0009] A top plate, a rotating plate is arranged on the top of the top plate, a liquid storage frame is fixedly arranged on the top of the rotating plate, a mounting groove is provided on the top of the top plate, a grinding cylinder is fixedly installed inside the mounting groove, and a plurality of filter holes are provided on the bottom side of the inner wall of the grinding cylinder;

[0010] A rotating mechanism, which is arranged on the top plate and is used to drive the rotating plate to rotate;

[0011] The adding mechanism is arranged on the top plate and is used for automatically adding the grinding liquid.

[0012] In a possible design, the rotating mechanism includes a rotating groove, which is opened at the top of the top plate. A rotating ring is rotatably connected inside the rotating groove. The rotating plate is fixedly arranged on the top of the rotating ring. A plurality of teeth are fixedly arranged on the outer wall of the rotating ring.

[0013] In a possible design, a motor is fixedly mounted on the bottom of the top plate, an output end of the motor passes through the bottom of the top plate and extends to the top of the top plate, and a gear meshing with a plurality of teeth is fixedly arranged on the output end of the motor via a coupling.

[0014] In one possible design, the adding mechanism includes a support frame, which is fixedly mounted on the top of the top plate. A liquid storage tank is arranged on the top of the support frame. One side of the liquid storage tank is connected to a liquid outlet pipe corresponding to the liquid storage frame. An electromagnetic valve is arranged on the outer wall of the liquid outlet pipe, and a liquid level sensor electrically connected to the electromagnetic valve is arranged on the inner wall of the liquid storage frame.

[0015] In a possible design, a water pump is fixedly mounted on the top of the rotating plate, and the water inlet and water outlet of the water pump are respectively connected to a water inlet pipe and a water outlet pipe, and one end of the water inlet pipe away from the water pump is connected to the liquid storage frame.

[0016] In a possible design, one end of the water outlet pipe away from the water pump is connected to an annular pipe, the annular pipe is fixedly mounted on the rotating plate, and the outer wall of the annular pipe is connected to a plurality of nozzles corresponding to the interior of the grinding cylinder.

[0017] In a possible design, fixed frames are fixed on both sides of the top plate, bottom plates are fixed at the bottom of the two fixed frames, a liquid collecting cylinder corresponding to the grinding cylinder is fixed on the top of the bottom plate, and a limiting ring for limiting the placement of the liquid collecting cylinder is fixed on the top of the bottom plate.

[0018] In the present application, first, the liquid storage tank is pre-filled with grinding liquid, and the liquid storage frame serves as a temporary storage container for the grinding liquid. Then, the workpiece to be processed is placed in the grinding cylinder. At this time, the water pump is turned on to start working, and the grinding liquid is extracted from the liquid storage frame and transported to the annular tube through the water inlet pipe and the water outlet pipe. Finally, the grinding liquid is sprayed onto the corresponding workpiece through multiple nozzles to complete the processing. At the same time, the motor is turned on to run, and the motor will drive the gear to rotate through the coupling. Since the gear is meshed with the teeth on the outer wall of the rotating ring, the rotation of the gear will drive the rotating ring to rotate slowly in the rotating groove, and then drive the rotating plate and the annular tube thereon to rotate together. The annular tube is fixed on the rotating plate, and the nozzle can be driven to rotate with the rotation of the rotating plate, so that the grinding liquid can be evenly sprayed onto the workpiece inside the grinding cylinder, so that the workpiece as a whole can be completely processed, which not only improves the processing effect, but also enhances the quality of the workpiece.

[0019] The used grinding liquid will pass through the multiple filter holes opened on the bottom side of the inner wall of the grinding cylinder and flow into the liquid collecting cylinder. The waste liquid can be collected by the liquid collecting cylinder for later treatment. The liquid collecting cylinder is placed on the bottom plate and is limited by the limit ring to ensure the stability and easy replacement of the liquid collecting cylinder, thereby improving the convenience and applicability. At the same time, during the removal of the grinding liquid, the liquid level sensor will monitor the grinding liquid level in the liquid storage frame in real time. When the liquid level is lower than the preset value, the liquid level sensor will send a signal to the solenoid valve to control the solenoid valve to open. At this time, the grinding liquid in the liquid storage tank will flow into the liquid storage frame through the liquid outlet pipe until the liquid level reaches the preset value. The solenoid valve is closed and the addition of grinding liquid stops, thereby achieving the effect of automatic addition of grinding liquid, ensuring that there is always enough grinding liquid supply in the liquid storage frame, thereby improving the use effect.

[0020] In the utility model, the automatic grinding liquid adding structure can drive the rotating plate and the annular tube thereon to rotate together through the rotating mechanism, and the nozzle can be driven to rotate with the rotation of the rotating plate, so that the grinding liquid can be evenly sprayed onto the workpiece inside the grinding cylinder;

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] Example 1

[0031] Please refer to Figure 1-Figure 4 , an adding structure, comprising:

[0032] A top plate 1 is provided with a rotating plate 8 on the top of the top plate 1, a liquid storage frame 9 is fixedly provided on the top of the rotating plate 8, a mounting groove is provided on the top of the top plate 1, a grinding cylinder 2 is fixedly installed inside the mounting groove, a plurality of filter holes 3 are provided on the bottom side of the inner wall of the grinding cylinder 2, the liquid storage frame 9 serves as a temporary storage container for the grinding liquid, the grinding cylinder 2 is convenient for placing the workpiece to be processed and for processing and use, and the used grinding liquid will pass through the plurality of filter holes 3 provided on the bottom side of the inner wall of the grinding cylinder 2 and flow into the liquid collecting cylinder 18.

[0033] A rotating mechanism is arranged on the top plate 1 to drive the rotating plate 8 to rotate. The rotating mechanism includes a rotating groove, which is opened on the top of the top plate 1. The internal rotation of the rotating groove is connected with a rotating ring 4. The rotating plate 8 is fixedly arranged on the top of the rotating ring 4. The outer wall of the rotating ring 4 is fixedly provided with a plurality of teeth 5. A motor 7 is fixedly installed on the bottom of the top plate 1. The output end of the motor 7 passes through the bottom of the top plate 1 and extends to the top of the top plate 1. The output end of the motor 7 is fixedly provided with a gear 6 meshing with the plurality of teeth through a coupling.

[0034] The motor 7 drives the gear 6 to rotate through the coupling. Since the gear 6 is meshed with the teeth 5 on the outer wall of the rotating ring 4, the rotation of the gear 6 drives the rotating ring 4 to rotate slowly in the rotating groove, thereby driving the rotating plate 8 and the annular tube 12 thereon to rotate together. The annular tube 12 is fixed on the rotating plate 8. As the rotating plate 8 rotates, the nozzle 13 can be driven to rotate, so that the grinding liquid can be evenly sprayed onto the workpiece inside the grinding cylinder 2, so that the entire workpiece can be completely processed, which not only improves the processing effect but also enhances the quality of the workpiece.

[0035] The adding mechanism is arranged on the top plate 1 for automatically adding the grinding liquid. The adding mechanism includes a support frame 14, and the support frame 14 is fixedly installed on the top of the top plate 1. A liquid storage tank 15 is arranged on the top of the support frame 14.

The outer wall of the liquid outlet pipe 16 is provided with a solenoid valve 17, and the inner wall of the liquid storage frame 9 is provided with a liquid level sensor 10 electrically connected to the solenoid valve 17.

[0036] During the process of removing the grinding liquid, the liquid level sensor 10 will monitor the grinding liquid level in the liquid storage frame 9 in real time. When the liquid level is lower than the preset value, the liquid level sensor 10 will send a signal to the solenoid valve 17 to control the solenoid valve 17 to open. At this time, the grinding liquid in the liquid storage tank 15 will flow into the liquid storage frame 9 through the liquid outlet pipe 16 until the liquid level reaches the preset value. The solenoid valve 17 is closed and the addition of grinding liquid stops, thereby achieving the effect of automatic addition of grinding liquid, ensuring that there is always enough grinding liquid supply in the liquid storage frame 9, and improving the use effect.

[0037] A water pump 11 is fixedly installed on the top of the rotating plate 8, and the water inlet and water outlet of the water pump 11 are respectively connected to the water inlet pipe and the water outlet pipe, the end of the water inlet pipe away from the water pump 11 is connected to the liquid storage frame 9, and the end of the water outlet pipe away from the water pump 11 is connected to the annular pipe 12, the annular pipe 12 is fixedly installed on the rotating plate 8, and the outer wall of the annular pipe 12 is connected to a plurality of nozzles 13 corresponding to the inside of the grinding cylinder 2. When the water pump 11 is turned on to start working, the grinding liquid is extracted from the liquid storage frame 9 and transported to the annular pipe 12 through the water inlet pipe and the water outlet pipe, and finally the grinding liquid is sprayed onto the corresponding workpiece through the plurality of nozzles 13 to complete the processing.

A liquid collecting cylinder 18 corresponding to the grinding cylinder 2 is provided on the top of the bottom plate 21, and a limiting ring 19 for limiting the position of the liquid collecting cylinder 18 is fixedly provided on the top of the bottom plate 21. Waste liquid can be collected by the liquid collecting cylinder 18 for later processing. The liquid collecting cylinder 18 is placed on the bottom plate 21 and is limited by the limiting ring 19 to ensure the stability and easy replacement of the liquid collecting cylinder 18, thereby improving the convenience and applicability.
