Description

Technical Field

[0001] The present application relates to the field of swing cylinder equipment, and in particular to a miniature swing cylinder. Background Art

[0002] As a common hydraulic actuator, the swing cylinder is widely used in industries, construction, agricultural machinery and other fields.

[0003] In the related technology, gears and racks are the more common driving methods of the swing cylinder. After long-term use, the driving parts of the swing cylinder need to be lubricated in time to effectively avoid the swing cylinder driving parts being in a friction state for a long time and causing failures, thereby affecting the normal use of the swing cylinder.

[0004] The traditional lubrication method requires stopping the oscillating cylinder first, and then manually filling the driving part with lubricating oil, which makes the oscillating cylinder unable to operate during the lubrication process, and thus easily affects the efficiency of the daily operation of the oscillating cylinder. At the same time, when manually filling the lubricating oil, the phenomenon of insufficient lubrication or over-lubrication often occurs, which is not conducive to the daily maintenance of the oscillating cylinder. Summary of the invention

[0005] The present application provides a micro swing oil cylinder, the purpose of which is to optimize the lubrication steps of the swing cylinder drive part, so that the swing cylinder operation and the lubrication of its drive part can be carried out simultaneously, thereby significantly improving the efficiency of the swing cylinder operation. At the same time, the lubrication of the swing cylinder drive part is effectively avoided to be insufficiently lubricated or over-lubricated.

[0006] The present application provides a micro swing cylinder, which adopts the following technical solution:

[0007] The transmission gear of the present invention is a gear selected from the group consisting of a first gear and a second gear selected from the group consisting of a first gear and a second gear selected from the group consisting of a first gear and a second gear selected from the group consisting of a first gear and a second gear selected from the group consisting of a first gear and a second gear selected from the group consisting of a first gear and a second gear selected from the group consisting of a first gear and a second gear selected from the group consisting of a first gear and a second gear selected from the group consisting of a first gear and a second gear selected from the group consisting of a first gear and a second gear selected from the group consisting of a

[0008] The driving rack is provided with a lubrication mechanism, and during the meshing process between the driving rack and the driving gear, the lubrication mechanism automatically lubricates the driving rack and the driving gear.

[0009] By adopting the above technical solution, when the cylinder body is rotating, the drive motor drives the screw rod to rotate, and during the rotation process, the screw rod drives the moving seat to slide in the horizontal direction, and then the moving seat synchronously drives the driving rack to slide in the horizontal direction, and during the sliding process, it meshes with the driving gear to drive the driving gear to rotate. When the driving gear rotates, it synchronously drives the first rotating shaft to rotate, and during the rotation process, the first rotating shaft synchronously drives the two rotating plates to rotate, and then the cylinder body is driven to rotate through the two rotating plates.

[0010] The lubrication mechanism lubricates the driving gear and the driving rack during their meshing process, which enables the operation of the swing cylinder and the lubrication of its driving parts to be carried out simultaneously, thereby significantly improving the efficiency of the operation of the swing cylinder. At the same time, it can effectively avoid the phenomenon of insufficient lubrication or excessive lubrication of the driving parts of the swing cylinder.

[0011] Preferably, the lubrication mechanism includes multiple groups of lubrication components, and the multiple groups of lubrication components are arranged inside the driving rack; the lubrication component is composed of two groups of lubricating parts, and the lubricating parts include a fixed pulley, a traction rope, a first sealing plate and a slider. The driving rack is provided with an oil storage chamber, and the oil storage chamber is used to fill lubricating oil. The fixed pulley is arranged in the oil storage chamber, and the traction rope is sleeved on the fixed pulley. The bottom of the tooth groove of the driving rack is penetrated by an array of oil outlet holes, and the first sealing plate is installed in the driving rack along the horizontal direction. The first sealing plate is used to seal or open the oil outlet hole, and the slider is slidably installed on the side wall inside the driving rack, and one side of the slider extends into the tooth groove outside the driving rack, one end of the traction rope is connected to the bottom of the first sealing plate, and the other end of the traction rope is connected to the slider, and the driving gear is used to drive the slider to slide.

[0012] By adopting the above technical solution, when the first sealing plate is in a sealed state with respect to the oil outlet, the lubricating oil in the oil storage chamber cannot flow into the tooth groove of the driving rack through the oil outlet. When the first sealing plate is in an open state with respect to the oil outlet, the lubricating oil in the oil storage chamber flows into the tooth groove of the driving rack through the oil outlet. The slider is in a "T"-shaped structure as a whole. When the teeth on the driving gear are inserted into the tooth groove of the driving rack, the driving gear abuts against the slider. As the driving gear rotates in the tooth groove of the driving rack, the driving gear drives the slider to slide. When the slider slides, the first sealing plate is pulled down by the traction rope. During the downward movement of the first sealing plate, the position of the oil outlet gradually opens, so that the lubricating oil can flow out from the position of the oil outlet to the tooth periphery side of the driving gear, thereby realizing lubrication during the rotation process between the driving gear and the driving rack.

[0013] When the teeth on the driving gear are engaged with the tooth grooves of the driving rack, the lubricating oil will flow out from the inside of the driving rack to the teeth of the driving gear. If the driving gear is not engaged with the driving rack, the first sealing plate of the non-engaged part seals the oil outlet hole, that is to say, the non-engaged part cannot be lubricated.

[0014] This setting method can accurately control the lubricated parts between the driving gear and the driving rack, that is, the meshing parts of the two will be lubricated, and the non-meshing parts will not be lubricated. This can effectively avoid the waste of lubricating oil and accurately control the lubricated parts of the two. At the same time, this lubrication method needs to be carried out during the meshing process of the driving gear and the driving rack, that is, the operation of the swing cylinder and the lubrication of its driving parts can be carried out at the same time, which can significantly improve the efficiency of the operation of the swing cylinder. At the same time, it can effectively avoid the phenomenon of insufficient lubrication or excessive lubrication of the lubrication of the driving parts of the swing cylinder.

[0015] Preferably, a first sliding groove for the sliding movement of the slider is opened on the side wall of the tooth groove of the driving rack, and a second sealing plate is installed on the side wall inside the driving rack. The second sealing plate cover is arranged on the peripheral side of the slider, and the second sealing plate is used to seal the position of the slider and the first sliding groove.

[0016] By adopting the above technical solution and using the second sealing plate to seal the first slide groove, it is possible to effectively prevent the lubricating oil in the oil storage chamber from leaking from the first slide groove.

[0017] Preferably, a support tube is installed in the driving rack along the setting direction, a reset spring is installed in the support tube along the vertical direction, a support rod is installed on the top of the support tube, the bottom of the support rod is integrally connected with the top of the reset spring, and the top of the support rod is integrally connected with a support plate along the horizontal direction, and the support plate is supported on the bottom of the first sealing plate.

[0018] By adopting the above technical solution, when the first sealing plate is not driven by the corresponding slider to move downward, the support plate is used to stably support the first sealing plate, so that the first sealing plate can be stably sealed at the oil outlet. When the driving gear is inserted into the tooth groove of the driving rack, the first sealing plate presses down the support plate during the downward movement, and the return spring is in a compressed state during this process. When the driving gear slides away from the tooth groove on the driving rack, the return spring recovers its deformation, and the return spring drives the first sealing plate to return to the oil outlet to reseal the oil outlet.

[0019] Preferably, a cooling box is additionally provided on the top of the installation box, a first air vent is provided through the bottom of the cooling box, and the cooling box is connected with the installation box through the first air vent.

[0020] By adopting the above technical solution, the cooling box is used to cool the driving gear and the driving rack in the installation box, thereby effectively preventing the high temperature generated during the meshing friction between the driving gear and the driving rack from affecting the lubricating oil.

[0021] Preferably, a rotating disk is added in the installation box in the horizontal direction, and a second air vent is opened through the rotating disk. The second air vent is opened on the side of the rotating disk, and the top of the rotating disk is tightly attached to the top of the installation box.

[0022] By adopting the above technical solution, during the rotation of the rotating disk: when the first air hole and the second air hole are aligned and connected, in this state, the cold air in the cooling box flows into the installation box through the first air hole and the second air hole to cool down the driving gear and the driving rack; when the first air hole and the second air hole are not aligned and connected, in this state, the peripheral side of the rotating disk seals the first air hole, and at this time, the cold air in the cooling box cannot enter the installation box for cooling.

[0023] The purpose of this is that if there is excessive cooling between the drive gear and the drive rack, it is easy to cause the viscosity of the lubricating oil to increase, which in turn leads to poor fluidity. High-viscosity lubricating oil cannot quickly reach the lubrication part when the mechanical parts are started or running at low speed, thereby reducing the lubrication effect.

[0024] Therefore, during the meshing process of the drive gear and the drive rack, the high temperature generated by the friction between the two will affect the lubrication effect of the lubricating oil, and a cooling box is needed to cool both of them. However, the cooling cannot be excessive. In other words, the drive gear and the drive rack need to be cooled during operation, but they cannot be cooled excessively.

[0025] By using the second air hole on the rotating disk, the cooling box can cool down the driving gear and the driving rack only when the second air hole is aligned and connected with the first air hole during the rotation of the rotating disk. The cooling box cannot play a cooling role at other times. This makes the cooling of the driving gear and the driving rack by the cooling box intermittent, so that the driving gear and the driving rack can be cooled while effectively avoiding overcooling.

[0026] Preferably, the side wall of the driving rack is integrally formed with a driven rack along the horizontal direction, the driven rack is meshed with a driven gear, the driven gear is horizontally arranged, the top of the driven gear is integrally connected to a second rotating shaft along a vertical defense line, and the top of the second rotating shaft is integrally connected to the bottom of the rotating disk.

[0027] By adopting the above technical solution, the driving rack synchronously drives the driven rack to slide during the sliding process, and the driven rack engages with the driven gear during the sliding process. After the driven gear engages, it starts to rotate and synchronously drives the second rotating shaft to rotate, and then drives the rotating disk to rotate through the second rotating shaft.

[0028] Preferably, a second slide groove is provided at the bottom of the cooling box in a horizontal direction, and a third sealing plate is slidably installed in the second slide groove in a horizontal direction, and the third sealing plate is used to seal or open the first air vent.

[0029] By adopting the above technical solution, when the swing cylinder stops working, the first air hole is sealed by the third sealing plate, which effectively prevents the cold air in the cooling box from leaking from the first air hole.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. The lubrication mechanism lubricates the driving gear and the driving rack during their meshing process, which enables the operation of the swing cylinder and the lubrication of its driving parts to be carried out simultaneously, thereby significantly improving the efficiency of the swing cylinder operation. At the same time, it can effectively avoid the phenomenon of insufficient lubrication or excessive lubrication of the driving parts of the swing cylinder;

[0032] 2. When the teeth on the driving gear are engaged with the tooth grooves of the driving rack, the lubricating oil will flow out from the inside of the driving rack to the teeth of the driving gear. If the driving gear is not engaged with the driving rack, the first sealing plate of the non-engaged part seals the oil outlet hole, that is to say, the non-engaged part cannot be lubricated.

[0033] This setting method can accurately control the lubrication parts between the driving gear and the driving rack, that is, the meshing parts of the two will be lubricated, and the non-meshing parts will not be lubricated. This can effectively avoid the waste of lubricating oil and can also accurately control the lubrication parts of the two. At the same time, this lubrication method needs to be carried out during the meshing process of the driving gear and the driving rack. In other words, the operation of the swing cylinder and the lubrication of its driving parts can be carried out at the same time, which can significantly improve the efficiency of the operation of the swing cylinder. At the same time, it can effectively avoid the phenomenon of insufficient lubrication or excessive lubrication of the driving parts of the swing cylinder;

[0034] 3. Using the second air hole on the rotating disk, the cooling box can cool down the driving gear and the driving rack only when the second air hole is aligned and connected to the first air hole during the rotation of the rotating disk. The cooling box cannot play a cooling role at other times. This makes the cooling of the driving gear and the driving rack by the cooling box intermittent, so that the driving gear and the driving rack can be cooled while effectively avoiding overcooling.

[0042] The following is combined with Figure 1 -Attached Figure 6 , further details of this application are given.

[0043] Example:

[0044] The present application discloses a micro swing cylinder. Figure 1 and Figure 2 , including a support seat 1 and a cylinder body 2, the cylinder body 2 is arranged above the support seat 1, and a driving mechanism for driving the cylinder body 2 to rotate is arranged on the top of the support seat 1. The driving mechanism includes a mounting box 3, a mounting tube 4, a driving motor 5, a screw 6, a moving seat 7, a driving rack 8, a driving gear 9, a first rotating shaft 10 and two rotating plates 11. The mounting box 3 and the mounting tube 4 are both fixed on the top of the support seat 1, the driving motor 5 is installed in the mounting tube 4, the screw 6 is connected to the driving end of the driving motor 5 in the horizontal direction, and the moving seat 7 is sleeved on the screw 6 in the vertical direction and is threadedly connected to the screw 6. The side wall of the driving rack 8 is integrally connected to the moving seat 7, and the driving gear 9 is meshed and installed on the top of the driving rack 8. The first rotating shaft 10 penetrates the driving gear 9 in the horizontal direction and is integrally connected to the driving gear 9. The left and right ends of the first rotating shaft 10 are respectively integrally connected to the two rotating plates 11. The left and right sides of the cylinder body 2 are respectively integrally connected to the two rotating plates 11.

[0045] When the cylinder body 2 is specifically rotating, the driving motor 5 drives the screw 6 to rotate, and the screw 6 drives the moving seat 7 to slide in the horizontal direction during the rotation process, and then drives the driving rack 8 to slide in the horizontal direction through the moving seat 7, and meshes with the driving gear 9 during the sliding process to drive the driving gear 9 to rotate. The driving gear 9 drives the first rotating shaft 10 to rotate synchronously while rotating, and the first rotating shaft 10 drives the two rotating plates 11 to rotate synchronously during the rotation process, and then drives the cylinder body 2 to rotate through the two rotating plates 11.

[0046] In this embodiment, the driving motor 5 is a variable speed motor, and the rotation speed of the cylinder body 2 is adjusted by the variable speed motor.

[0047] At the same time, a lubrication mechanism is provided on the driving rack 8, and the lubrication mechanism automatically lubricates the driving rack 8 and the driving gear 9 during the meshing process. This enables the operation of the swing cylinder and the lubrication of its driving parts to be carried out simultaneously, thereby significantly improving the efficiency of the operation of the swing cylinder. At the same time, it can effectively avoid the phenomenon of insufficient lubrication or excessive lubrication of the driving parts of the swing cylinder.

[0048] Specifically, refer to Figure 3 , Figure 4 as well as Figure 5 , the lubrication mechanism includes a plurality of lubrication components, which are arranged inside the driving rack 8. The lubrication component is composed of two groups of lubricating parts, which include a fixed pulley 12, a traction rope 13, a first sealing plate 14 and a slider 15. The driving rack 8 is hollow inside, and the cavity inside the driving rack 8 is used as an oil storage chamber 16, and the oil storage chamber 16 is filled with corresponding lubricating oil. The fixed pulley 12 is arranged in the oil storage chamber 16, and the traction rope 13 is sleeved on the fixed pulley 12. An array of oil outlet holes 17 are opened through the bottom of the tooth groove of the driving rack 8, and the first sealing plate 14 is installed in the driving rack 8 in the horizontal direction. The first sealing plate 14 is used to seal or open the oil outlet hole 17. When the first sealing plate 14 is in a sealing state with respect to the oil outlet hole 17, the lubricating oil in the oil storage chamber 16 cannot flow into the tooth groove of the driving rack 8 through the oil outlet hole 17. When the first sealing plate 14 is in an open state with respect to the oil outlet hole 17, the lubricating oil in the oil storage chamber 16 flows into the tooth groove of the driving rack 8 through the oil outlet hole 17. The slider 15 is a "T"-shaped structure as a whole. The slider 15 is slidably mounted on the side wall inside the driving rack 8, and one side of the slider 15 extends into the tooth groove outside the driving rack 8.

[0049] One end of the traction rope 13 is connected to the bottom of the first sealing plate 14 , and the other end of the traction rope 13 is connected to the slider 15 .

[0050] When the teeth on the driving gear 9 are inserted into the tooth grooves of the driving rack 8, the driving gear 9 contacts the slider 15, and as the driving gear 9 rotates in the tooth grooves of the driving rack 8, the driving gear 9 drives the slider 15 to slide. When the slider 15 slides, the first sealing plate 14 is pulled downward by the traction rope 13. During the downward movement of the first sealing plate 14, the position of the oil outlet 17 is gradually opened, so that the lubricating oil can flow out from the position of the oil outlet 17 to the tooth periphery side of the driving gear 9, thereby achieving lubrication between the driving gear 9 and the driving rack 8 during the rotation process.

[0051] When the teeth on the driving gear 9 are engaged with the tooth grooves of the driving rack 8, the lubricating oil will flow out from the inside of the driving rack 8 to the teeth of the driving gear 9. If the driving gear 9 is not engaged with the driving rack 8, the first sealing plate 14 of the non-engaged part seals the oil outlet 17, that is, the non-engaged part cannot be lubricated.

[0052] This setting method can accurately control the lubricated parts between the driving gear 9 and the driving rack 8, that is, the meshing parts of the two will be lubricated, and the non-meshing parts will not be lubricated. Therefore, it can effectively avoid the waste of lubricating oil and accurately control the lubricated parts of the two. At the same time, this lubrication method needs to be carried out during the meshing process of the driving gear 9 and the driving rack 8, that is, the operation of the swing cylinder and the lubrication of its driving parts can be carried out at the same time, which can significantly improve the efficiency of the operation of the swing cylinder. At the same time, it can effectively avoid the phenomenon of insufficient lubrication or excessive lubrication of the lubrication of the driving parts of the swing cylinder.

[0053] Further, refer to Figure 5 and Figure 6 The side wall of the tooth groove of the driving rack 8 is provided with a first slide groove 18 for the sliding block 15 to slide. At the same time, a second sealing plate 19 is installed on the side wall inside the driving rack 8. The second sealing plate 19 is covered on the side of the slider 15. The second sealing plate 19 seals the position of the slider 15 and the first slide groove 18, thereby effectively preventing the lubricating oil in the oil storage chamber 16 from leaking from the first slide groove 18.

[0054] Further, refer to Figure 5 and Figure 6 A support cylinder 20 is installed in the driving rack 8 along the setting direction, a return spring 21 is installed in the support cylinder 20 along the vertical direction, a support rod 22 is installed on the top of the support cylinder 20, and the bottom of the support rod 22 is integrally connected to the top of the return spring 21. A support plate 23 is integrally connected to the top of the support rod 22 along the horizontal direction, and the support plate 23 is supported on the bottom of the first sealing plate 14.

[0055] When the first sealing plate 14 is not driven by the corresponding slider 15 to move downward, the support plate 23 is used to stably support the first sealing plate 14, so that the first sealing plate 14 can be stably sealed at the oil outlet 17. After the driving gear 9 is inserted into the tooth groove of the driving rack 8, the first sealing plate 14 presses down the support plate 23 during the downward movement, and the return spring 21 is in a compressed state during this process. After the driving gear 9 slides away from the tooth groove on the driving rack 8, the return spring 21 recovers its deformation, and the return spring 21 drives the first sealing plate 14 to return to the oil outlet 17 to reseal the oil outlet 17.

[0056] Further, refer to Figure 1 , Figure 2 as well as Figure 3 A cooling box 24 is added to the top of the installation box 3, and a circular first air hole 25 is formed through the bottom of the cooling box 24. Meanwhile, a through hole connected to the first air hole 25 is formed through the top of the installation box 3, and the cooling box 24 and the installation box 3 are connected by the through hole and the first air hole 25. The cooling box 24 is used to cool the driving gear 9 and the driving rack 8 in the installation box 3, thereby effectively preventing the high temperature generated during the meshing friction between the driving gear 9 and the driving rack 8 from affecting the lubricating oil.

[0057] Furthermore, a rotating disk 26 is provided in the installation box 3 in the horizontal direction, and a circular second air hole 27 is provided through the rotating disk 26, and the second air hole 27 is provided on the side of the rotating disk 26. The top of the rotating disk 26 is tightly attached to the top of the installation box 3.

[0058] During the rotation of the rotating disk 26: when the first air hole 25 and the second air hole 27 are aligned and connected, in this state, the cold air in the cooling box 24 flows into the installation box 3 through the first air hole 25 and the second air hole 27 to cool the driving gear 9 and the driving rack 8; when the first air hole 25 and the second air hole 27 are not aligned and connected, in this state, the peripheral side of the rotating disk 26 seals the first air hole 25, and at this time, the cold air in the cooling box 24 cannot enter the installation box 3 for cooling.

[0059] The purpose of this is that if excessive cooling occurs between the driving gear 9 and the driving rack 8, the viscosity of the lubricating oil will increase, which will lead to poor fluidity. The high-viscosity lubricating oil cannot quickly reach the lubrication part when the mechanical parts are started or run at low speed, thereby reducing the lubrication effect.

[0060] Therefore, during the meshing process of the driving gear 9 and the driving rack 8, the high temperature generated by the friction between the two will affect the lubrication effect of the lubricating oil, and the cooling box 24 is required to cool both of them. However, the cooling should not be excessive. In other words, the driving gear 9 and the driving rack 8 need to be cooled during operation, but they should not be cooled excessively.

[0061] By using the second air holes 27 on the rotating disk 26, during the rotating process of the rotating disk 26, the cooling box 24 can cool down the driving gear 9 and the driving rack 8 only when the second air holes 27 and the first air holes 25 are aligned and connected. The cooling box 24 cannot play a cooling role at other times. This makes the cooling of the driving gear 9 and the driving rack 8 by the cooling box 24 intermittent, so that the driving gear 9 and the driving rack 8 can be cooled while effectively avoiding overcooling.

[0062] In summary, during the operation of the oscillating cylinder, the lubrication between the driving gear 9 and the driving rack 8 is continuous, while the cooling is intermittent, thereby significantly improving the lubrication effect between the driving gear 9 and the driving rack 8.

[0063] Specifically, refer to Figure 2 and Figure 3 The side wall of the driving rack 8 is integrally formed with a driven rack 28 in the horizontal direction, and a driven gear 29 is meshed and connected to the driven rack 28, and the driven gear 29 is arranged horizontally. The top of the driven gear 29 is integrally connected with a second rotating shaft 30 along the vertical defense line, and the top of the second rotating shaft 30 is integrally connected with the bottom of the rotating disk 26.

[0064] The driving rack 8 synchronously drives the driven rack 28 to slide during the sliding process. The driven rack 28 meshes with the driven gear 29 during the sliding process. After the driven gear 29 meshes, it starts to rotate and synchronously drives the second rotating shaft 30 to rotate, and then drives the rotating disk 26 to rotate through the second rotating shaft 30.

[0065] In this embodiment, there are two second air holes 27, which are spaced apart and distributed around the rotating disk 26. The second air holes 27 are provided in two numbers, which is beneficial to improving the cooling efficiency of the cooling box 24 for the driving gear 9 and the driving rack 8.

[0066] Further, refer to Figure 2 and Figure 3 A second slide groove 31 is horizontally provided at the bottom of the cooling box 24 , and a third sealing plate 32 is horizontally slidably installed in the second slide groove 31 . The third sealing plate 32 is used to seal or open the first air vent 25 .

[0067] When the swing cylinder stops working, the first air hole 25 is sealed by the third sealing plate 32 , thereby effectively preventing the cold air in the cooling box 24 from leaking from the first air hole 25 .

[0068] The implementation principle of a micro swing cylinder in the embodiment of the present application is:

[0069] When the teeth on the driving gear 9 are engaged with the tooth grooves of the driving rack 8, the lubricating oil will flow out from the inside of the driving rack 8 to the teeth of the driving gear 9. If the driving gear 9 is not engaged with the driving rack 8, the first sealing plate 14 of the non-engaged part seals the oil outlet 17, that is, the non-engaged part cannot be lubricated.

[0070] This setting method can accurately control the lubricated parts between the driving gear 9 and the driving rack 8, that is, the meshing parts of the two will be lubricated, and the non-meshing parts will not be lubricated. Therefore, it can effectively avoid the waste of lubricating oil and accurately control the lubricated parts of the two. At the same time, this lubrication method needs to be carried out during the meshing process of the driving gear 9 and the driving rack 8, that is, the operation of the swing cylinder and the lubrication of its driving parts can be carried out at the same time, which can significantly improve the efficiency of the operation of the swing cylinder. At the same time, it can effectively avoid the phenomenon of insufficient lubrication or excessive lubrication of the lubrication of the driving parts of the swing cylinder.

[0071] During the rotation of the rotating disk 26: when the first air hole 25 and the second air hole 27 are aligned and connected, in this state, the cold air in the cooling box 24 flows into the installation box 3 through the first air hole 25 and the second air hole 27 to cool the driving gear 9 and the driving rack 8; when the first air hole 25 and the second air hole 27 are not aligned and connected, in this state, the peripheral side of the rotating disk 26 seals the first air hole 25, and at this time, the cold air in the cooling box 24 cannot enter the installation box 3 for cooling.

[0072] The purpose of this is that if excessive cooling occurs between the driving gear 9 and the driving rack 8, the viscosity of the lubricating oil will increase, which will lead to poor fluidity. The high-viscosity lubricating oil cannot quickly reach the lubrication part when the mechanical parts are started or run at low speed, thereby reducing the lubrication effect.

[0073] Therefore, during the meshing process of the driving gear 9 and the driving rack 8, the high temperature generated by the friction between the two will affect the lubrication effect of the lubricating oil, and the cooling box 24 is required to cool both of them. However, the cooling should not be excessive. In other words, the driving gear 9 and the driving rack 8 need to be cooled during operation, but they should not be cooled excessively.

[0074] By using the second air holes 27 on the rotating disk 26, during the rotating process of the rotating disk 26, the cooling box 24 can cool down the driving gear 9 and the driving rack 8 only when the second air holes 27 and the first air holes 25 are aligned and connected. The cooling box 24 cannot play a cooling role at other times. This makes the cooling of the driving gear 9 and the driving rack 8 by the cooling box 24 intermittent, so that the driving gear 9 and the driving rack 8 can be cooled while effectively avoiding overcooling.

[0075] In summary, during the operation of the oscillating cylinder, the lubrication between the driving gear 9 and the driving rack 8 is continuous, while the cooling is intermittent, thereby significantly improving the lubrication effect between the driving gear 9 and the driving rack 8.

[0076] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
