DETAILED DESCRIPTION

[0040] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0041] Embodiment 1:

[0042] like Figures 1 to 3 and Fig.11As shown, a turret machine includes a turret machine body 1, which includes a machine body 101, a first processing part 102, a second processing part 103, a housing 104, a mounting platform 105 and a driving device 106. A guide rail 107 for guiding the second processing part 103 is installed on the outer surface of the machine body 101, and a slider 108 slidably connected to the guide rail 107 is fixedly installed on the outer surface of the mounting platform 105; the first processing part 102 and the second processing part 103 are distributed on both sides of the machine body 101, and the driving device 106 is arranged outside the machine body 101. A rotating seat connected to the second processing part 103 is arranged on the outer surface of the housing 104, and the housing 104 is fixedly installed on a side of the mounting platform 105 away from the machine body 101 by multiple sets of bolts. By setting the first processing part 102 and the second processing part 103, the two processing parts have different processing responsibilities, which reduces the steps of transporting products from one machine tool to another machine tool, and improves production efficiency.

[0043] It should be noted that the driving device 106 can be a hydraulic telescopic rod or a motor screw drive mechanism. The hydraulic telescopic rod and the motor screw drive are respectively located at the bottom and top sides of the machine body 101. The two modes of the driving device 106 are not limited and can be used according to needs. The second processing part 103 is driven by the above two modes.

[0044] In this embodiment, a triangular support plate is provided on the machine body 101, and the triangular support plate is located behind the second processing part 103. The three sides of the triangular support plate are respectively connected to the machine body 101 to form a stable triangular structure, which can resist forces in all directions. When the triangular support plate is subjected to external force, the force will be dispersed to each side of the triangle, avoiding the upper half of the turret machine body 1 being subjected to the gravity of the second processing part 103 and concentrating on the upper half of the turret machine body 1, thereby improving the stability of the structure.

[0045] Specifically, the triangular support plate is provided with a plurality of reinforcing ribs, and the plurality of reinforcing ribs are connected to form a plurality of grooves. In this embodiment, the triangular support plate is provided with twenty-two reinforcing ribs, and the twenty-two reinforcing ribs form fifteen grooves. The grooves are neatly distributed on the triangular support plate, transferring stress from the high stress area to the surrounding area, achieving uniform stress distribution, which is conducive to preventing excessive stress concentration at the location of the second processing part 103 of the structure, and improving the stability and durability of the overall structure.

[0046] Embodiment 2:

[0047] like Figure 1 , Figure 3 - Fig.10As shown, a lubricating device 2 for lubricating the guide rail 107 is installed on one side of the mounting platform 105 close to the machine body 101, and the lubricating device 2 includes an oil storage structure 3, an oil delivery structure 4, a driving structure 5 and a linkage structure; the oil storage structure 3 includes an oil storage shell 301 and a stirring rod 302; the oil delivery structure 4 includes a pump shell 401, a piston 402, two groups of valve pipes 403, two groups of check valve plates 404 and a valve stem 405, and the outer surface of one of the check valve plates 404 is fixedly connected to the oil storage shell 3 01 internal connecting pipe 406; the driving structure 5 includes a mounting shell 501, a rotating arm 502, a connecting sleeve 503 and a gear 504, the top end of the valve stem 405 extends to the inside of the mounting shell 501 and is fixed to the outer surface of the connecting sleeve 503; the linkage structure is composed of a roller 7, a rolling seat 8 and a rack 9, the roller 7 is connected and fixed to one end of the stirring rod 302, and the roller 7 is rollingly connected to the outer surface of the rolling seat 8, the gear 504 is fixed to one end of the rotating arm 502 and meshes with the rack 9. By extending and retracting the driving device 106, the oil storage structure 3 is lifted and moved. At this time, the roller 7 is rollingly connected to the outer surface of the rolling seat 8 to drive the stirring rod 302 to rotate, so as to achieve the stirring of the lubricating oil and improve the activity of the lubricating oil. When the oil storage structure 3 is lifted and lowered, the gear 504 is meshed with the rack 9 to drive the rotating arm 502 to rotate. The rotation of the rotating arm 502 drives the piston 402 to reciprocate through the valve stem 405. The piston 402 continuously changes the pressure in the chamber when it reciprocates. The lubricating oil in the oil storage shell 301 is extracted through the connecting pipe 406, and the two check valve plates 404 are opened and closed, and finally sprayed out through the nozzle 407, thereby achieving the lubrication of the guide rail 107 and the slider 108.

[0048] This lubrication method has the following advantages: such as extending the service life of the guide rail 107 and the slider 108: sufficient lubrication can reduce the friction and wear between the guide rail 107 and the slider 108, reduce heat generation, and thus extend their service life. Improve the movement accuracy of the guide rail 107 and the slider 108: lubrication can reduce the friction resistance between the guide rail 107 and the slider 108, making their movement smoother and more accurate, and improving the movement accuracy of the equipment. Reduce noise and vibration: lubrication can reduce dry friction and viscous friction between the guide rail 107 and the slider 108, thereby reducing noise and vibration and improving the stability and reliability of the equipment. Energy saving and environmental protection: This lubrication method can achieve precise lubricating oil injection and recovery, reduce lubricating oil waste and emissions, and meet environmental protection requirements. At the same time, its efficient lubrication effect also helps to reduce the energy consumption cost of the equipment.

[0049] Specifically, the oil storage shell 301 is hollow inside, the stirring rod 302 is horizontally bearing-mounted inside the oil storage shell 301, and both ends of the stirring rod 302 extend to the outside of the oil storage shell 301. There are two rollers 7 and two rolling seats 8, and the two rolling seats 8 are symmetrically mounted on one side of the body 101 close to the oil storage shell 301, and the two rollers 7 are bearing-mounted on both ends of the stirring rod 302. The oil storage structure 3 is lifted and moved by the extension and contraction of the driving device 106. At this time, the roller 7 is rollingly connected with the outer surface of the rolling seat 8 to drive the stirring rod 302 to rotate, so as to achieve the stirring of the lubricating oil and improve the activity of the lubricating oil.

[0050] like Figure 4 As shown, a connecting rod 6 is bolted between the oil storage shell 301 and the mounting platform 105, and the oil storage shell 301 moves up and down according to the extension and contraction of the driving device 106, and the roller 7 is rollingly connected to the outer surface of the rolling seat 8 to drive the stirring rod 302 to rotate, thereby stirring the lubricating oil.

[0051] like Figure 6 As shown, two valve tubes 403 are symmetrically fixed and connected to the inside of the pump housing 401. A chamber is provided inside the pump housing 401, and a piston 402 is reciprocated in the chamber. Two check valve plates 404 are elastically hinged and installed in the two valve tubes 403. The other end of the valve tube 403 away from the connecting pipe 406 is rotatably provided with a nozzle 407 for lubricating the guide rail 107. The installation angle of the nozzle 407 can be adjusted so that it can be adjusted and used according to needs. Specifically, the oil delivery structure 4 has the same working principle as the piston pump, and the piston 402 is used for reciprocating motion. The piston 402 continuously changes the pressure in the chamber when it reciprocates, and the lubricating oil in the oil storage shell 301 is extracted through the connecting pipe 406, and the two check valve plates 404 are opened and closed, and finally sprayed out through the nozzle 407, thereby realizing the lubrication of the guide rail 107 and the slider 108.

[0052] Specifically, the interior of the mounting shell 501 is hollow, the mounting shell 501 is fixedly mounted on the top side of the pump housing 401, and a communicating through-hole is provided on the side where the mounting shell 501 is connected to the pump housing 401, and the valve stem 405 extends out of the pump chamber and passes through the through-hole to extend into the mounting shell 501. Both ends of the rotating arm 502 are connected to the internal bearing of the mounting shell 501, the connecting sleeve 503 is rotatably mounted on the outer surface of the middle part of the rotating arm 502, the bottom end of the valve stem 405 is connected to the piston 402 via a universal ball joint, and the diameter of the through-hole is adapted to the swing amplitude of the valve stem 405. The rack 9 is fixedly mounted on the side of the body 101 close to the lubrication device 2, and the gear 504 is meshed with the rack 9.

[0053] This lubrication method also has the following advantages and beneficial effects: Easy maintenance: The structure of the lubrication system is relatively simple, and the connection and transmission methods between the various components are also relatively intuitive, so it is more convenient to perform maintenance and servicing. Due to the high degree of automation of the system, the frequency of manual intervention is reduced, thereby reducing maintenance costs and difficulties. Strong adaptability: This lubrication method can adapt to guide rails 107 and sliders 108 of different models and specifications, and has strong versatility and adaptability. By adjusting parameters such as the stroke of the drive device 106 and the speed of the stirring rod 302, flexible response to different lubrication needs can be achieved. High reliability:

[0054] The lubrication system uses a mechanical structure for transmission and lubrication. Compared with electronic control systems, it has higher reliability and is not easily affected by factors such as electromagnetic interference and temperature. The connection and coordination between each component are carefully designed to ensure the stability and durability of the system.

[0055] Beneficial effects of the lubrication equipment in this example: Improve equipment performance: Adequate lubrication can reduce the frictional resistance between the guide rail 107 and the slider 108, and improve the movement performance and response speed of the equipment. A stable lubrication state helps to maintain the accuracy and stability of the equipment, thereby improving the overall performance of the equipment. Reduce production costs: By reducing the wear and replacement frequency of the guide rail 107 and the slider 108, the maintenance cost and downtime of the equipment are reduced. Efficient lubrication methods help reduce the energy consumption and lubricant consumption of the equipment, further reducing production costs. Improve the working environment: Lubrication can reduce noise and vibration during equipment operation, thereby improving the working environment and increasing employee comfort and work efficiency. Environmentally friendly lubrication methods also help reduce environmental pollution and meet the requirements of sustainable development.

[0056] In summary, this lubrication method has significant advantages and beneficial effects in terms of maintenance simplicity, adaptability, reliability, improving equipment performance, reducing production costs, and improving the working environment. These advantages and effects jointly promote the efficient, stable, and environmentally friendly operation of the equipment, providing strong support for the production and development of the enterprise.

[0057] like Figure 1 - Fig.11 As shown, the principle of the turret machine with lubrication function provided in this embodiment is as follows:

[0058] When the present invention is used, the oil storage structure 3 is lifted and lowered by extending and retracting the driving device 106. At this time, the roller 7 is rollingly connected to the outer surface of the rolling seat 8 to drive the stirring rod 302 to rotate, thereby stirring the lubricating oil and improving the activity of the lubricating oil. When the oil storage structure 3 is lifted and lowered, the gear 504 is meshed with the rack 9 to drive the rotating arm 502 to rotate. The rotation of the rotating arm 502 drives the piston 402 to reciprocate through the valve stem 405. The piston 402 continuously changes the pressure in the chamber when it reciprocates. The lubricating oil in the oil storage shell 301 is extracted through the connecting pipe 406, and the two check valve plates 404 are opened and closed, and finally sprayed out through the nozzle 407, thereby achieving lubrication of the guide rail 107 and the slider 108.

[0059] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction.

"Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0060] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
