Description

Technical Field

[0001] The invention belongs to the technical field of coolant treatment devices for machine tools, and in particular relates to a high-efficiency cooling and lubricating liquid circulation distribution device for vertical turning, milling and grinding compound machine tools. Background Art

[0002] In the machining process of vertical turning, milling and grinding compound machine tools, cooling lubricant plays a vital role. It can not only reduce the friction between the tool and the workpiece, reduce wear, improve machining accuracy and surface quality, but also take away a large amount of heat generated during the machining process to prevent the workpiece and tool from being damaged due to overheating. However, as the machining continues, a large amount of metal debris and impurities will gradually mix into the cooling lubricant. If these impurities are not removed in time, they will have a serious impact on the performance of the cooling lubricant, thereby affecting the machining effect and service life of the machine tool.

[0003] At present, the existing cooling and lubricating liquid circulation and distribution devices have many shortcomings in coolant filtration. Most devices use simple filtering structures, such as ordinary filters. Although they can filter out some larger metal debris, they are not effective in filtering fine metal impurities. As the use time increases, these fine metal impurities will gradually accumulate in the cooling and lubricating liquid, causing the viscosity of the coolant to increase and the heat dissipation performance to decrease. At the same time, it may also cause wear and scratches on the hydraulic system, tool and workpiece surface of the machine tool.

[0004] In addition, the existing filtering devices also have obvious defects in the cleaning of the filter cartridge. During long-term use, the side walls of the filter cartridge will gradually be attached with a large amount of metal debris and impurities. These impurities will block the pores of the filter cartridge and reduce the circulation speed and filtration efficiency of the coolant. In order to ensure the filtering effect, the operator needs to frequently disassemble and clean the filter cartridge, which not only increases labor costs and maintenance workload, but also increases machine tool downtime and affects production efficiency. Moreover, the filter cartridge may be damaged during the disassembly and cleaning process, further shortening the service life of the filter cartridge. Summary of the invention

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0020] Example 1: Reference Figure 1-8 , a high-efficiency cooling and lubricating liquid circulation and distribution device for a vertical lathe-milling and grinding compound machine tool, comprising a machine body 1, a movable seat 101 and a fixture 103 are installed on the machine body 1, a tool holder 102 is installed on the movable seat 101, and also comprising: a coolant collecting tank 2, installed in the machine body 1, and the coolant collecting tank 2 is used to collect the coolant flowing out of the machine body 1; a motor 401, fixedly connected in the coolant collecting tank 2, a cross slot 402 is fixedly connected to the output end of the motor 401, and a cross shaft 403 is slidably connected in the cross slot 402; an arc wall 201, fixedly connected in the coolant collecting tank 2; a push rod 404, fixedly connected to the cross shaft 403, and an end of the push rod 404 away from the cross shaft 403 is slidably connected to the arc wall 201; filter cartridge 3, connected to the coolant collecting tank 2, the coolant flowing out of the machine body 1 will flow into the filter cartridge 3, one end of the cross shaft 403 passes through the filter cartridge 3, the through end of the cross shaft 403 is a cylinder, the bottom of the cylinder is fixedly connected with a top plate, the top plate is used to support the filter cartridge 3 and move up and down following the cross shaft 403, the cross shaft 403 is fixedly connected with a rotating rod 405, the rotating rod 405 is provided with a groove, a knocking assembly is provided in the groove, a plurality of protrusions 301 are fixedly connected to the filter cartridge 3 at equal intervals, the knocking assembly can contact with the protrusion 301 and vibrate, a water pump 202 is installed on the coolant collecting tank 2, a connecting pipe 203 is provided on the liquid inlet end of the water pump 202, and the connecting pipe 203 is connected to the coolant collecting tank 2.

[0021] The machine body 1 in the present device is the basic supporting structure of the whole device, on which a moving seat 101 and a clamp 103 are installed. The moving seat 101 can drive the tool holder 102 to move its position so as to perform processing operations on the workpiece at different positions. The clamp 103 is used to fix the workpiece to ensure the stability of the processing process. At the same time, the cooling and distribution of the coolant are the functions of the machine tool PLC control system and are prior art. At the same time, the coolant can stably flow into the filter cartridge 3. The coolant after cutting can be collected by a collecting bucket and then introduced into the filter cartridge 3 through a hose. The specific structure will not be described in detail here.

[0022] The coolant collecting tank 2 is installed in the machine body 1, and is used to collect the coolant containing metal debris and impurities flowing out of the machine body 1. The motor 401 is fixed in the coolant collecting tank 2, and its output end is connected to the cross slot 402. The cross shaft 403 is slidably connected in the cross slot 402. The arc wall 201 is fixed in the coolant collecting tank 2. The push rod 404 is fixedly connected to the cross shaft 403, and the end of the push rod 404 away from the cross shaft 403 slides on the arc wall 201. The filter cartridge 3 is fixed in the coolant collecting tank 2, and the coolant flowing out of the machine body 1 flows into the filter cartridge 3 for preliminary filtration. The cross shaft 4 One end of 03 passes through the filter cartridge 3, and its passing end is a cylinder. The top plate at the bottom of the cylinder presses against the filter cartridge 3. When the motor 401 drives the cross shaft 403 to rotate, the top rod 404 slides on the arc wall 201 (the arc wall 201 is a complete circular wave plate), which will cause the cross shaft 403 to drive the filter cartridge 3 to move up and down. In the process of the filter cartridge 3 moving up and down, the liquid will not be discharged quickly through the filter holes in cooperation with the filter holes on the filter cartridge 3, which makes the liquid in the filter cartridge 3 have enough time to fully contact with the inner wall of the filter cartridge 3, so that the impurities attached to the inner wall of the filter cartridge 3 can be shaken off and fall into the bottom of the filter cartridge 3.

[0023] A rotating rod 405 is fixedly connected to the cross shaft 403, and a groove is formed on the rotating rod 405. A knocking assembly is arranged in the groove. A plurality of protrusions 301 are fixed at equal intervals on the filter cartridge 3. When the cross shaft 403 rotates, the rotating rod 405 rotates accordingly, and the knocking assembly contacts the protrusion 301 and vibrates, which helps to shake off impurities attached to the side wall of the filter cartridge 3.

[0024] A water pump 202 is installed on the coolant collecting tank 2. The liquid inlet end of the water pump 202 is connected to the coolant collecting tank 2 through a connecting pipe 203, so that the filtered coolant can be transported back to the processing part of the machine tool for recycling.

[0025] Example 2: Reference Figure 1-8, a high-efficiency cooling and lubricating liquid circulation and distribution device for a vertical turning, milling and grinding compound machine tool is basically the same as Example 1, and further: the knocking component includes a spring member 4051 and a knocking block 4052, the spring member 4051 is connected in the groove, the knocking block 4052 is slidably connected in the groove, and one end of the knocking block 4052 is connected to the spring member 4051.

[0026] The knocking assembly includes a spring member 4051 and a knocking block 4052. The spring member 4051 is connected to the groove of the rotating rod 405. The knocking block 4052 can slide in the groove, and one end is connected to the spring member 4051. When the rotating rod 405 rotates and the knocking block 4052 contacts the protrusion 301 on the filter cartridge 3, the spring member 4051 will undergo elastic deformation and then quickly recover, so that the knocking block 4052 has a knocking effect on the protrusion 301, thereby enhancing the vibration effect and more effectively shaking off impurities on the side wall of the filter cartridge 3.

[0027] Example 3: Reference Figure 1-8 , a high-efficiency cooling and lubricating liquid circulation and distribution device for a vertical lathe-milling and grinding compound machine tool is basically the same as Example 2, and further: two groups of piston cylinders 5 are fixedly connected in the coolant collection tank 2, and the telescopic ends of the two groups of piston cylinders 5 are both against the push rod 404. Through the up and down movement of the push rod 404, the telescopic ends of the two groups of piston cylinders 5 can be continuously squeezed, so that the first group of piston cylinders 5 can continuously inhale the filtered coolant, and a water spray ring 602 is connected to the filter cartridge 3, and a plurality of water outlet holes are provided on the water spray ring 602. The water spray ring 602 is connected to the liquid outlet end of the first group of piston cylinders 5, and the first The liquid outlet end of the first group of piston cylinders 5 is connected to a coolant discharge pipe 501, which is connected to a water spray ring 602. The liquid outlet end of the second group of piston cylinders 5 is connected to a gas discharge pipe 502. The liquid inlet end of the piston cylinder 5 is connected to an air intake pipe, which runs through the coolant collection tank 2 and is used to inhale external gas. An expansion airbag 601 is fixedly connected to the water spray ring 602. The gas discharge pipe 502 is connected to the expansion airbag 601. The expansion airbag 601 is connected to a pressure relief pipe. A ring plate is fixedly connected to the push rod 404, and the ring plate abuts against the telescopic end of the piston cylinder 5.

[0028] Two groups of piston cylinders 5 are fixed in the coolant collection tank 2. The telescopic ends of the two groups of piston cylinders 5 are both against the push rod 404. The up and down movement of the push rod 404 will continuously squeeze the telescopic ends of the two groups of piston cylinders 5. The first group of piston cylinders 5 continuously inhales the filtered coolant. At this time, the liquid outlet end of the first group of piston cylinders 5 is connected to the water spray ring 602 through the coolant discharge pipe 501. There are multiple water outlet holes on the water spray ring 602, which can spray the coolant onto the filter cartridge 3, backwash the filter cartridge 3, remove impurities in the pores of the filter cartridge 3, and facilitate the long-term use of the filter cartridge 3.

[0029] At the same time, under normal circumstances, the coolant collection tank 2 is filled with coolant. Since the liquid inlet end of the second group of piston cylinders 5 is connected to the air inlet pipe, the air inlet pipe runs through the coolant collection tank 2 to inhale external gas. The liquid outlet end of the second group of piston cylinders 5 is connected to the expansion airbag 601 through the gas discharge pipe 502, and the expansion airbag 601 can be inflated. At this time, as the internal gas increases, the buoyancy of the expansion airbag 601 is greater than its own gravity, overcoming the downward force caused by gravity. At this time, the expansion airbag 601 will float in the water with the water spray ring 602, and gradually move upward as the gas increases (the expansion airbag 601 is connected to a pressure relief pipe for controlling the air pressure in the expansion airbag 601. When the limit is reached, the gas is discharged to prevent the air pressure from being too high, and the expansion airbag 601 and the water spray ring 602 are sunk into the water, which is convenient for subsequent cleaning and use).

[0030] At this time, in this way, the water spray ring 602 can continuously spray coolant to clean the inner wall of the filter cartridge 3, and can also continuously move up and down in the coolant, thereby achieving comprehensive cleaning of the inner wall of the filter cartridge 3, reducing the blockage of the filter holes of the filter cartridge 3, and facilitating long-term use.

[0031] The ring plate on the push rod 404 abuts against the telescopic end of the piston cylinder 5 , ensuring that the push rod 404 can stably squeeze the telescopic end of the piston cylinder 5 .

[0032] Example 4: Reference Figure 1-8 , a high-efficiency cooling and lubricating liquid circulation and distribution device for a vertical turning, milling and grinding compound machine tool is basically the same as Example 3, and further: an inflatable airbag 302 is connected to the bottom of the filter cartridge 3, and a partition 303 is connected to the inflatable airbag 302, and a plurality of filter holes are arranged on the partition 303, and the partition 303 is sleeved on the cylinder and abuts against the inner wall of the filter cartridge 3, and a gas exhaust pipe 1 502 is connected to a gas exhaust pipe 2 503, and the gas exhaust pipe 2 503 is connected to the expansion airbag 601, and a plurality of magnetic suction rods 7 are fixedly connected to the cylinder, and the magnetic suction rods 7 are used to absorb metal chips on the partition 303, and a pressure relief pipe is connected to the inflatable airbag 302.

[0033] An inflatable airbag 302 is connected to the bottom of the filter cartridge 3, and a partition 303 is connected to the inflatable airbag 302. The partition 303 has multiple filter holes, and the partition 303 is sleeved on the cylinder of the cross shaft 403 and abuts against the inner wall of the filter cartridge 3. When the inflatable airbag 302 is inflated, the partition 303 will be lifted up.

[0034] The gas discharge pipe 1 502 is connected to the gas discharge pipe 2 503, and the gas discharge pipe 2 503 is connected to the inflatable airbag 601. A plurality of magnetic rods 7 are fixed on the cylinder. When the partition 303 is lifted up and the metal debris in the filter cartridge 3 is close to the magnetic rods 7, the magnetic rods 7 can absorb the metal debris on the partition 303, thereby effectively collecting the metal debris. The inflatable airbag 302 is also connected to a pressure relief pipe for controlling the air pressure in the inflatable airbag 302. When the inflatable airbag 302 reaches the limit, the gas is discharged to restore to normal.

[0035] It should be noted that after the inflatable airbag 302 is expanded, the space occupied by the coolant collecting tank 2 is reduced as much as possible to avoid the coolant overflowing from the coolant collecting tank 2, and the magnetic suction rod 7 needs to be cleaned after the work is completed to avoid the situation where multiple groups of metal debris are attached and cannot continue to be adsorbed.

[0036] The present invention can filter the metal debris in the coolant and reduce the metal impurities in the coolant through the setting of the filter cartridge 3. At the same time, through the setting of the arc wall 201 and the push rod 404, the filter cartridge 3 can be continuously moved up and down to shake off some impurities attached to the side walls of the filter cartridge 3, which is convenient for the discharge of the coolant. Subsequently, through the setting of two groups of piston cylinders 5, the expansion airbag 601 and the water spray ring 602, the expansion airbag 601 can be inflated to make it continuously move up and down in the coolant. At the same time, through the setting of the water spray ring 602, the filter cartridge 3 can be backwashed, and then the filter cartridge 3 can be continuously cleaned for long-term use. Finally, the partition 303 can be lifted up by the inflatable airbag 302, and then the metal debris in the filter cartridge 3 can be lifted up to make it close to the magnetic suction rod 7, and finally the metal debris is collected by the magnetic suction rod 7.

[0037] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with the present invention can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
