Description

Technical Field

[0001] The utility model relates to the field of milling machines, in particular to a milling machine for processing aluminum profiles. Background Art

[0002] Aluminum alloy has low density but relatively high strength, close to or exceeding that of high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry and its usage is second only to steel.

[0003] During the production and processing of aluminum profiles, milling machines are needed to process the profiles into workpieces of specific shapes. At present, the operating tables of milling machines are mostly moved by lead screw nuts. This simple structure is convenient for workers to operate the workpiece, but the lead screw nuts need to be lubricated to prevent rust and poor movement. Most of the existing methods are to oil the lead screw nuts regularly by hand, which is not only troublesome, but also cannot guarantee the smooth operation of the lead screw nuts in real time.

[0004] For this reason, we use this technical solution to solve the problem that the existing milling machine lead screw nut cannot self-lubricate. Utility Model Content

[0005] The utility model aims to improve the milling machine in the prior art and to provide a milling machine for aluminum profile processing compared with the prior art. By adding an oil absorption pad on the basis of the existing milling machine, self-lubrication of the lead screw is achieved. Lubricating oil is pre-filled into the elastic oil storage bag. The pressure generated by the expansion of the elastic oil storage bag after the oil is added automatically inputs the lubricating oil into the fixed oil delivery seat to be absorbed by the oil absorption pad. The oil absorption pad automatically applies the lubricating oil to the lead screw, which not only saves the trouble of manual application, but also ensures the smooth operation of the lead screw in real time, and also effectively avoids excessive waste of lubricating oil.

[0006] Furthermore, the oil absorption pad is in the shape of a semicircular ring, and an elastic adaptive pad is fixedly connected between the oil absorption pad and the side wall of the fixed oil delivery seat. The two oil absorption pads are distributed on both sides of the screw to hold the screw. In this way, the oil absorption pad can automatically apply lubricating oil to the screw to achieve self-lubrication of the screw. The elastic adaptive pad relies on elastic force to press the oil absorption pad tightly against the screw, ensuring a close fit between the oil absorption pad and the screw, effectively improving the application effect.

[0007] Furthermore, the interior of the elastic oil storage bag is also filled with an elastic net, and the elastic net is made of oil-proof elastic material. When lubricating oil is added to the elastic oil storage bag, the elastic oil storage bag expands and accumulates pressure. Relying on the pressure, the elastic oil storage bag can automatically transport the lubricating oil to the oil absorption pad, and the elastic net further effectively enhances the pressure of the elastic oil storage bag, so that as much lubricating oil stored in the elastic oil storage bag as possible can be transported to the oil absorption pad, thereby effectively avoiding waste of lubricating oil.

[0008] Optionally, the self-sealing oil filling tube includes a tube sleeve, an inner wall of which is fixedly connected to an oil sealing plate, and a filling port is opened in the middle of the oil sealing plate, and an oil sealing head matching it is placed on the filling port, and a plurality of symmetrically distributed elastic threads are also fixedly connected between the oil sealing head and the inner wall of the tube sleeve. When filling oil, the filling tube pushes the oil sealing head inward to separate the oil sealing head from the oil sealing plate, so that the filling tube can add the lubricating oil into the elastic oil storage bag, and when the filling tube is evacuated, the elastic force of the elastic thread makes the oil sealing head and the oil sealing plate fit tightly together for sealing, so that the lubricating oil in the elastic oil storage bag will not leak out from the self-sealing oil filling tube, and the self-sealing oil filling tube thus plays a role of one-way circulation.

[0009] Optionally, the oil sealing head and the filling port are magnetically attracted to each other, and a sealing gasket is fixedly connected to the outer surface of the oil sealing head. The magnetic attraction makes the oil sealing head and the filling port fit tightly, and the sealing gasket additionally increases the sealing performance, effectively preventing the lubricating oil from leaking out.

[0010] Optionally, the movable platform body is also fixedly connected to the side walls on both sides of the operating platform body, and the side walls of the operating platform body are provided with guide grooves matching the guide strips. When the lead screw is rotated to move the operating platform body, the guide strips can guide the operating platform body to improve stability and effectively prevent the operating platform body from shaking when moving.

[0011] Compared with the prior art, the advantages of the present invention are:

[0012] (1) This scheme realizes self-lubrication of the screw by adding an oil absorption pad on the basis of the existing milling machine. By pre-filling the lubricating oil into the elastic oil storage bag, the pressure generated by the expansion of the elastic oil storage bag after the oil is filled will automatically input the lubricating oil into the fixed oil delivery seat and be absorbed by the oil absorption pad. The oil absorption pad will automatically apply the lubricating oil to the screw, which not only saves the trouble of manual application, but also ensures the smooth operation of the screw in real time, and also effectively avoids excessive waste of lubricating oil.

[0013] (2) The oil absorption pad is in the shape of a semicircular ring, and an elastic adaptive pad is fixedly connected between the oil absorption pad and the side wall of the fixed oil delivery seat. The two oil absorption pads are distributed on both sides of the lead screw to hold the lead screw. In this way, the oil absorption pad can automatically apply lubricating oil to the lead screw to achieve self-lubrication of the lead screw. In addition, the elastic adaptive pad relies on elastic force to press the oil absorption pad tightly against the lead screw, ensuring that the oil absorption pad and the lead screw are closely fitted, effectively improving the application effect.

[0014] (3) The interior of the elastic oil storage bag is also filled with an elastic net, and the elastic net is made of oil-proof elastic material. When lubricating oil is added to the interior of the elastic oil storage bag, the elastic oil storage bag expands and accumulates pressure. Relying on the pressure, the elastic oil storage bag can automatically transport the lubricating oil to the oil absorption pad, and the elastic net further effectively enhances the pressure of the elastic oil storage bag, so that as much lubricating oil stored in the elastic oil storage bag as possible can be transported to the oil absorption pad, thereby effectively avoiding the waste of lubricating oil.

[0015] (4) The self-sealing oil filling pipe includes a pipe sleeve, the inner wall of which is fixedly connected to an oil sealing plate, and a filling port is opened in the middle of the oil sealing plate, on which a matching oil sealing head is placed, and between the oil sealing head and the inner wall of the pipe sleeve, a plurality of symmetrically distributed elastic threads are fixedly connected. When filling oil, the filling pipe pushes the oil sealing head inward, and the oil sealing head is separated from the oil sealing plate, so that the filling pipe can add lubricating oil to the elastic oil storage bag. When the filling pipe is evacuated, the elastic force of the elastic thread makes the oil sealing head and the oil sealing plate fit tightly together for sealing, so that the lubricating oil in the elastic oil storage bag will not leak out from the self-sealing oil filling pipe, and the self-sealing oil filling pipe thus plays a role of one-way flow.

[0016] (5) The oil sealing head and the filling port are magnetically attracted to each other, and a sealing gasket is fixedly connected to the outer surface of the oil sealing head. The magnetic attraction makes the oil sealing head and the filling port fit tightly, and the sealing gasket further increases the sealing performance, effectively preventing the lubricating oil from leaking out.

[0017] (6) The movable platform body is located on both side walls of the operating platform body and is fixedly connected with guide bars, and the side walls of the operating platform body are provided with guide grooves matching the guide bars. When the lead screw is rotated to move the operating platform body, the guide bars can guide the operating platform body to improve stability and effectively prevent the operating platform body from shaking when moving.

The two oil absorption pads 6 are distributed on both sides of the lead screw 4 to hold the lead screw 4. In this way, the oil absorption pad 6 can automatically apply lubricating oil to the lead screw 4 to achieve self-lubrication of the lead screw 4. The elastic adaptive pad relies on elastic force to press the oil absorption pad 6 against the lead screw 4, ensuring that the oil absorption pad 6 and the lead screw 4 are closely fitted, effectively improving the application effect;

[0029] See also Figure 2 , 3 and Figure 7The inner walls of both sides of the mobile platform body 2 located at the operating table body 3 are provided with oil sac cavities 201, and an elastic oil storage bag 8 filled with lubricating oil is placed in the oil sac cavity 201 (oil-resistant rubber material is preferably selected, and other materials can also be selected according to actual needs), the lower inner wall of the mobile platform body 2 is provided with an oil delivery pipe 202 connected to the elastic oil storage bag 8, and the inner wall of the fixed oil delivery seat 5 is provided with an oil delivery cavity 501 connected to the oil delivery pipe 202, and the inner wall of the mobile platform body 2 near the oil sac cavity 201 is fixedly inlaid with a self-sealing oil filling pipe 7, and the self-sealing oil filling pipe 7 is fixedly inlaid with the inner wall of the mobile platform body 2 near the oil sac cavity 201. The sealed oil filling pipe 7 is connected to the elastic oil storage bag 8 through a hose. The interior of the elastic oil storage bag 8 is also filled with an elastic net 801, and the elastic net 801 is made of oil-proof elastic material. When lubricating oil is added to the interior of the elastic oil storage bag 8, the elastic oil storage bag 8 expands and accumulates pressure. Relying on the pressure, the elastic oil storage bag 8 can automatically transport the lubricating oil to the oil absorption pad 6, and the elastic net 801 further effectively enhances the pressure of the elastic oil storage bag 8, so that the lubricating oil stored in the elastic oil storage bag 8 can be transported to the oil absorption pad 6 as much as possible, thereby effectively avoiding the waste of lubricating oil.

[0030] Example 2: Based on Example 1, please refer to Figure 5 , 6 The self-sealing oil filling pipe 7 includes a pipe sleeve 701, an inner wall of the pipe sleeve 701 is fixedly connected with an oil sealing plate 702, and a filling port is opened in the middle of the oil sealing plate 702, an oil sealing head 703 and the filling port are magnetically attracted to each other, and a sealing gasket is fixedly connected to the outer surface of the oil sealing head 703, and the magnetic attraction makes the oil sealing head 703 fit tightly with the filling port, and the sealing gasket increases the sealing performance and effectively prevents the lubricating oil from leaking out, and a matching oil sealing head 703 is placed on the filling port, and the oil sealing head 703 and the inner wall of the pipe sleeve 701 are connected. A plurality of symmetrically distributed elastic threads 704 are fixedly connected therebetween. When filling oil, the filling pipe pushes the oil sealing head 703 inward, and the oil sealing head 703 is separated from the oil sealing plate 702, so that the filling pipe can add lubricating oil into the elastic oil storage bag 8. When the filling pipe is evacuated, the elastic force of the elastic thread 704 makes the oil sealing head 703 and the oil sealing plate 702 fit tightly together to seal, so that the lubricating oil in the elastic oil storage bag 8 will not leak out from the self-sealing oil filling pipe 7, and the self-sealing oil filling pipe 7 thus plays a role of one-way flow.

[0031] See also Figure 2 The side walls of the movable platform body 2 on both sides of the operating platform body 3 are also fixedly connected with guide bars 9, and the side walls of the operating platform body 3 are provided with guide grooves matching the guide bars 9. When the lead screw 4 is rotated to move the operating platform body 3, the guide bars 9 can guide the operating platform body 3 to improve stability and effectively prevent the operating platform body 3 from shaking when moving.

[0032] The working principle of this scheme is as follows: first, lubricating oil is added with the help of a filling pipe. When the filling pipe is inserted into the interior of the pipe sleeve 701, the oil sealing head 703 is pushed inward, so that the oil sealing head 703 is separated from the filling port on the oil sealing plate 702, so that the lubricating oil can be injected into the elastic oil storage bag 8. During the filling process, the lubricating oil is filled into the elastic oil storage bag 8 by pressurizing. During the filling process, the elastic oil storage bag 8 continues to expand and accumulates pressure. When the filling pipe is evacuated, the oil sealing head 703 is sealed and connected to the filling pipe again under the rebound force of the elastic wire 704. In this way, the lubricating oil is squeezed into the oil delivery cavity 501 under the contraction force of the elastic oil storage bag 8 and absorbed by the oil absorption pad 6. In this way, during the rotation of the screw 4, the oil absorption pad 6 continuously applies the lubricating oil to the screw 4, thereby achieving self-lubrication.

[0033] The above is only the best implementation method adopted by the present utility model in combination with current actual needs, but the protection scope of the present utility model is not limited to this.
