Description

Technical Field

[0001] The invention relates to the technical field of machine tool equipment, and in particular to a heavy-duty grinding machine platform. Background Art

[0002] The conventional lubrication method used in machine tools is generally to inject lubricating oil from the side of the linear guide slider, thereby lubricating the guide rail and reducing wear.

[0003] This type of lubrication has a small flow rate and insufficient lubrication. The lubricating oil is easily mixed with the cutting fluid during use, and is also easily mixed with impurities such as dust and iron filings. It is not only difficult to reuse, but also causes certain pollution to the environment, thereby reducing the utilization rate of the lubricating oil.

[0004] Especially for some heavy-duty grinder or planer machine tool processing platforms, since their processing platforms need to move back and forth repeatedly for a long time, and the machine body requires faster movement speed and larger load, a large amount of lubricating oil needs to be injected. This conventional lubrication method is difficult to support the normal operation of the machine tool. Summary of the invention

[0005] To this end, the present invention provides a heavy-duty grinding machine platform to solve the problem in the prior art that the utilization rate of lubricating oil is low due to the conventional lubrication method used in the machine tool.

[0015] Furthermore, two pairs of pressure wheels are installed at the bottom of the processing platform, and a hose is installed at the bottom of each pair of pressure wheels. The end of the hose is connected to a three-way joint. The upper end of the three-way joint is connected to the injection hole through a connecting pipe, and the lower end is connected to the oil storage tank through a one-way valve.

[0016] Furthermore, a liquid level gauge is provided on the top of the oil return tank. When the liquid level of the lubricating oil measured by the liquid level gauge reaches the set liquid point, the oil suction pump will recover the lubricating oil in the oil return tank and pump it away, so that the lubricating oil in the oil return tank is maintained at a safe liquid level.

[0017] Furthermore, an editable logic controller is installed on the oil suction pump. When the liquid level in the oil return tank reaches the lowest point, the editable logic controller starts timing.

[0020] Furthermore, the base includes a movable base and a processing base, the oil return groove is arranged on the movable base, and the processing base is fixedly arranged on the side of the movable base.

[0021] Furthermore, the movable base and the processing base are both hollow structures and are made of cast iron.

DETAILED DESCRIPTION

[0038] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Please refer to Figure 1-Figure 8 The present invention discloses a heavy-duty grinding machine platform, which can circulate lubricating oil, thereby effectively reducing the amount of lubricating oil used and reducing the cost of using machine tools. The main structure of the platform includes a base 1, an oil return groove 2, an oil injection slider 3 and a guide rail 4. Among them, a pair of oil return grooves 2 are arranged in parallel on the top of the base 1 along the length direction, and an oil guide rail 4 is arranged in the oil return groove 2, and the two guide rails 4 are kept parallel. On this basis, if Figure 5 A number of oil injection sliders 3 are slidably mounted on the guide rail 4, and a number of oil injection sliders 3 are screwed and fixed to the bottom of the processing platform 5, so that the processing platform 5 can move along the guide rail 4. The bottom of the oil injection slider 3 is slidably embedded in the guide rail 4, and an injection hole 16 is provided on the top of the oil injection slider 3, and a flow channel 17 connected to the injection hole 16 is provided on the side of the oil injection slider 3. When the processing platform 5 moves, the lubricating oil is injected from the injection hole 16 through the flow channel 17, and flows directly into the oil return groove 2 through the guide rail 4.

[0040] In this embodiment, if Figure 4The base 1 includes a mobile base 1-1 and a processing base 1-2. The oil return groove 2 is arranged on the top of the mobile base 1-1, and the mobile base 1-1 is provided with liquid return grooves 6 on both sides, which are used to recover the coolant. The bottom of the liquid return groove 6 is connected with the collecting groove. After the used coolant is collected in the collecting groove, it is recycled into the machine tool for reuse. It should be noted that the width of the processing platform 5 is greater than the distance between the two oil return grooves 2. Since the bottom of the processing platform 5 is screwed and fixed on the oil injection slider 3, and a channel is provided on the side of the platform, the coolant is collected in the liquid return groove 6 through the channel, and the lubricating oil enters the oil return tank 9 through the oil return groove 2 for reuse, thereby avoiding the mixing of the coolant and the lubricating oil, and improving the utilization rate of the lubricating oil. In addition, a processing base 1-2 is fixedly provided on the side of the mobile base 1-1, and the processing base 1-2 is used to install milling equipment so as to process the blank.

[0041] In this embodiment, the movable base 1-1 and the processing base 1-2 are both hollow structures and made of cast iron, thereby reducing the weight while avoiding deformation of the base 1.

[0042] In this embodiment, if Figure 1 A pair of protective covers 7 are provided at the front and rear ends of the processing platform 5. The protective covers 7 are flexible materials in a folded or superimposed state, which can be stretched forward and backward and cover the positions of the liquid return tank 6 and the oil return tank 2, thereby preventing external dust or iron filings from entering and preventing the problem of pipeline blockage.

[0043] Further, such as Figure 1 and Figure 2 On the basis of this embodiment, in order to re-inject the lubricating oil flowing out of the oil return groove 2 into the oil injection slider 3, a lubrication circulation system is also installed, specifically, it includes an oil return tank 9 and a radiator 11. In terms of structure, the top of the oil return tank 9 is connected with the oil return groove 2 so that the lubricating oil can be collected in the oil return tank 9, and the side of the oil return tank 9 is connected with the oil storage tank 8 through the oil suction pump 10. At the same time, a liquid level meter 13 is provided on the top of the oil return tank 9. Figure 7 When the level of the lubricating oil measured by the level meter 13 reaches the set level point, the oil suction pump 10 will recover the lubricating oil in the return oil tank 9 and keep the lubricating oil in the return oil tank 9 at a safe level. In addition, a radiator 11 is provided on the top of the oil storage tank 8. The radiator 11 can dissipate heat by air cooling or liquid cooling, thereby reducing the temperature inside the oil storage tank 8, thereby reducing the evaporation of the lubricating oil, and thereby reducing the consumption of the lubricating oil. The oil storage tank 8 is connected to the injection hole 16, thereby achieving the technical effect of flowing the lubricating oil into the guide rail 4.

[0044] In some embodiments, the oil storage tank 8 is connected to the injection hole 16 through a solenoid valve, and the position height of the oil storage tank 8 is higher than the processing platform 5, so that when the solenoid valve is opened, the lubricating oil can automatically flow into the injection hole 16 to lubricate the guide rail. On this basis, as a preferred solution, the position height of the oil storage tank 8 can also be adjusted by an automatic lifting mechanism, thereby adjusting the injection pressure of the lubricating oil into the injection hole 16 by changing the gravitational potential energy of the lubricating oil.

[0045] In this embodiment, an editable logic controller is installed on the oil suction pump 10. When the liquid level in the oil return tank 9 reaches the lowest point, the editable logic controller starts timing. After a specified time, the oil suction pump 10 performs the operation of recovering the lubricating oil.

[0046] In some embodiments, Figure 8 Two pairs of pressing wheels 12 are installed at the bottom of the processing platform 5. A hose 01 is installed at the bottom of any pair of pressing wheels 12. The hose 01 has good elasticity. Since the processing platform 5 needs to move back and forth, it will drive the pressing wheel 12 to repeatedly roll on the hose 01. The end of the hose 01 is connected with a three-way joint 02. The upper end of the three-way joint 02 is connected to the injection hole 16 through the connecting pipe 04, and the lower end is connected to the oil storage tank 8 through the one-way valve 03. In the process of repeated rolling of the hose 01, negative pressure will be generated in the process of the hose 01 recovering its shape, thereby sucking the lubricating oil into the hose 01, and entering the injection hole 16 from the connecting pipe 04 under the pressure of the pressing wheel 12, thereby achieving the effect of automatically injecting lubricating oil into the oil injection slider 3, and the flow rate of the injected lubricating oil will also increase with the increase of the reciprocating frequency of the processing platform 5, thereby avoiding the problem of insufficient lubricating oil supply due to excessive processing speed.

[0047] In some embodiments, Figure 6 , the oil return tank 2 is connected to the filter tank, and the filter tank is connected to the oil storage tank 8, and the filter tank can filter impurities in the lubricating oil. Among them, the filter tank includes a tank body 21, a baffle 22 and a debris removal hole 23. The end of the oil return tank 3 on the base 1 is connected to the tank body 21. A plurality of baffles 22 are arranged in the tank body 21, and the tank body 21 is divided into a plurality of partitions 24. When the lubricating oil enters the tank body 21, it will first enter the first partition 24 to gather and precipitate. When the first partition 24 is full, it overflows and enters the second partition 24 to gather and precipitate. By analogy, the lubricating oil is precipitated through the partition 24, so that impurities can be effectively removed before the lubricating oil enters the oil storage tank 8, the lubrication effect of the platform is improved, the speed of deterioration of the lubricating oil is delayed, and the utilization rate of the lubricating oil is improved. A debris removal hole 23 is arranged at the bottom of any partition 24, and the accumulated and precipitated impurities can be discharged through the debris removal hole 23, thereby avoiding the problem of siltation.

[0048] In the embodiment, optionally, an oil filling pump 15 is provided on the top of the oil storage tank 8, the oil suction pump 10 is connected to the output end of the radiator 11, and the lubricating oil is directly dissipated through the radiator 11, the input end of the radiator 11 is connected to the pressure regulating filter 14, the pressure regulating filter 14 is connected to the oil storage tank 8, the oil storage tank 8 is connected to the oil filling pump 15, and a limit switch is installed in the oil storage tank 8. When the liquid level height of the lubricating oil in the oil storage tank 8 triggers the limit switch, the oil filling pump 15 injects the lubricating oil into the oil filling slider 3.

[0049] In this embodiment, Figure 3 The pressure regulating filter 14 includes a filter cartridge 141, a regulating valve 142, a pressure regulating gauge 143 and an oil injection pressure gauge 144. The oil injection pump 15 is connected to the filter cartridge 141 through the regulating valve 142. The filter cartridge 141 is connected to the injection hole 16 through the oil injection pressure gauge 144. The regulating valve 142 is equipped with a pressure regulating gauge 143.

[0050] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
