The adjusting mechanism is provided to absorb the impact of the moving plate by the first air bag, so that the moving plate is always in the best state during the conveying process. The cooperation of the first electromagnetic block and the metal plate realizes the fine adjustment and locking of the depth of the chute, prevents the first air bag from deforming due to pressure fluctuation or load change, and forms a rigid support.

[0004] In combination with the above case and actual situation, we find the following problems: when the arc-shaped track is used, manual observation of the track condition is required, and then the track is sprayed with lubricating oil to prevent the device from being damaged.

By setting a lubricating assembly, in the moving process of the sliding plate, the transmission structure drives the rotating rod to rotate and drives the threaded rod to rotate, thereby driving the movable rod and the piston to move up and down.

[0054] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings, but it should be understood that the scope of protection of the present application is not limited by the specific embodiments.

[0055] Unless otherwise explicitly stated, throughout the specification, the term "comprise" or its variants such as "comprises" or "comprising" will be understood to encompass the stated element or elements, but not to exclude other elements or other components.

[0056] REFERENCE Figures 1-13 As shown in the drawings, the present embodiment provides a technical solution:

[0057] The large-diameter multi-section arc-shaped guide rail assembly based on high-speed precision gear transmission device comprises a track 200, a sliding plate 300 slidingly installed on the track 200, and a driving member 500 for driving the sliding plate 300. A bottom plate 100 is fixed below the track 200. It should be noted that the outer edge of the bottom plate 100 is provided with a tooth portion. The driving member 500 drives the high-speed precision gear to rotate on the tooth portion of the bottom plate 100 to drive the sliding plate 300 to rotate through a driving device. Meanwhile, the track 200 is an arc. In use, each arc-shaped guide rail assembly can be combined and connected through welding or pin connection, etc. The above are all prior art of the large-diameter multi-section arc-shaped guide rail assembly, which will not be described in detail here. The bottom plate 100 is provided with a lubricating assembly 400 for spraying lubricating oil. The oil storage barrel 600 is arranged in the middle of the top surface of the bottom plate 100. By arranging the lubricating assembly 400, the lubricating oil can be sprayed according to the movement of the sliding plate 300, and manual spraying is not required, thereby reducing labor cost.

[0058] The lubricating assembly 400 comprises two sets of transmission structures 410 located on the inner and outer sides of the track 200, two rotating rods 401 in transmission connection with the two sets of transmission structures 410, a threaded rod 403 fixed coaxially with the bottom end of the rotating rod 401, and a movable rod 404 in threaded connection with the threaded rod 403. The rotating rod 401 is driven to rotate by the transmission structure 410, the threaded rod 403 is driven to rotate, and the movable rod 404 is driven to move up and down.

[0059] The transmission structure 410 comprises a cam 411, a top plate 412 located on the inner side of the cam 411, and a hinged rod 413. One end of the hinged rod 413 is hingedly connected to the inner end of the top plate 412, and the other end is hingedly connected to the top surface of the rotating rod 401 near the edge. When the protruding part of the cam 411 contacts the inner end of the top plate 412, it will press the top plate 412 inward and push the rotating rod 401 to rotate through the hinged rod 413.

[0060] The oil storage barrel 600 is provided with a vertical oil suction pipe 405, and the movable rod 404 is in the shape of an L. The horizontal section of the movable rod 404 penetrates the wall of the oil suction pipe 405 and extends into the interior thereof. The bottom end of the vertical section of the movable rod 404 is fixed with a piston 404a. The wall of the oil suction pipe 405 is provided with a plurality of regularly distributed oil outlet pipes 407 on the inner side. The inner bottom end of the oil suction pipe 405 and the inner end of the oil outlet pipe 407 are both provided with a one-way valve 406. The outer end of the oil outlet pipe 407 is connected with a nozzle 408. When the threaded rod 403 rotates and pushes the movable rod 404 to move upward, it will drive the piston 404a to move upward, and then the lubricating oil in the oil storage barrel 600 will be sucked into the oil suction pipe 405 through the one-way valve 406. When the threaded rod 403 rotates and pushes the movable rod 404 to move downward, it will drive the piston 404a to move downward, and then the lubricating oil in the oil suction pipe 405 will be pressed into the oil outlet pipe 407 through the one-way valve 406 and sprayed from the nozzle 408 to the track 200 to achieve lubrication.

[0061] Please refer to Figures 1-5 As shown in the figure, the two cams 411 are symmetrically fixed on the bottom surface of the sliding plate 300 near the inner and outer sides. The protruding part of the cam 411 is arranged inward, so that the cam 411 can contact the top plate 412. The outer end of the top plate 412 is an arc-shaped protruding section corresponding to the protruding part of the cam 411. When the cam 411 contacts the top plate 412, it can push the top plate 412 to slide inward. The top plate 412 has smaller resistance to the cam 411, avoiding too large resistance to the sliding plate 300, which causes the sliding plate 300 to be greatly disturbed. An installation plate 414 is arranged below the top plate 412. The bottom end of the installation plate 414 is fixed on the bottom plate 100. Limiting plates 415 are fixed on the upper and lower surfaces of the installation plate 414. The top plate 412 penetrates the bottom end of the corresponding installation plate 414 and is in sliding connection with the corresponding limiting plate 415. The sliding of the top plate 412 is limited by the installation plate 414 and the limiting plate 415, so that the top plate 412 can only slide linearly. The limiting plate 415 can prevent the top plate 412 from being separated from the installation plate 414.

[0062] As shown in Figures 6-7 The bottom plate 100 is fixed with a limiting rod 402 on both sides of the track 200, the middle of the rotating rod 401 penetrates through the corresponding limiting rod 402, the limiting rod 402 supports and limits the position of the rotating rod 401, the middle of the rotating rod 401 is embedded in the corresponding limiting rod 402, and the spring 402a is arranged between the middle of the rotating rod 401 and the corresponding limiting rod 402. When the cam 411 pushes the top plate 412 to slide inward and drives the rotating rod 401 to rotate, the spring 402a is deformed to store energy. When the cam 411 is separated from the top plate 412, the spring 402a is released, and the threaded rod 403 is quickly rotated, so that the piston 404a quickly moves downward, and the lubricating oil is sprayed from the nozzle 408 to the track 200 with enough power. The limiting rod 402 is provided with a baffle 409 below and on the right side of the corresponding rotating rod 401, which blocks the rotating rod 401 to avoid the rotating rod 401 from rotating too much under the action of the spring 402a and returning to the original position. The top end of the rotating rod 401 is disc-shaped, and one end of the hinged rod 413 hinged to the corresponding rotating rod 401 is always located on the left half of the rotating rod 401, so that the rotating rod 401 rotates in a fixed direction when it is driven by the hinged rod 413 to slide inward, avoiding the error of oil suction and oil injection time and causing the lubricating assembly 400 to be unable to use.

[0063] In addition, Figures 9-12 The bottom end of the rotating rod 401 extends into the oil storage barrel 600, the outer partition plate 601 is fixed in the oil storage barrel 600, and the outer partition plate 601 is located below the threaded rod 403. The outer partition plate 601 separates the space above the piston 404a from the oil storage barrel 600, avoiding the piston 404a from failing to complete oil suction and oil injection. The inner partition plate 405a is fixed in the oil suction pipe 405, and the piston 404a is located below the inner partition plate 405a. The bottom end of the oil suction pipe 405 communicates with the oil storage barrel 600 through the corresponding one-way valve 406. The inner partition plate 405a keeps the oil suction pipe 405 sealed. It should be noted that the one-way valve 406 at the bottom of the oil suction pipe 405 only allows lubricating oil to enter the oil suction pipe 405, and the one-way valve 406 between the oil suction pipe 405 and the oil outlet pipe 407 only allows lubricating oil to leave the oil suction pipe 405, thereby ensuring the operation of the lubricating assembly 400.

[0064] As shown in Figure 8 and Figure 13As shown, the bottom plate 100 is provided with an oil tank groove 101, the oil storage tank 600 is fixed in the oil tank groove 101, the bottom plate 100 is provided with a fan-shaped swing groove 102 above the oil tank groove 101, the swing groove 102 is provided with a swing structure 420 for driving the nozzle 408 to move, the swing structure 420 includes two arc rods 421 arranged on the inner and outer sides of the track 200 and two connecting rods 422 for connecting the two arc rods 421, the curvature of the arc rod 421 is matched with the curvature of the inner and outer sides of the track 200, so that the arc rod 421 always keeps the same distance with the track 200 when rotating, avoiding the distance being too large to spray lubricating oil on the track 200, and the connecting rod 422 is arranged in the swing groove 102.

[0065] In addition, the nozzle 408 is arc-shaped and matched with the curvature of the inner and outer sides of the track 200, so that the nozzle 408 always keeps in contact with the track 200 when swinging, avoiding the distance being too large to spray lubricating oil on the track 200, the nozzle 408 is inclined upward towards the inner and outer sidewalls of the track 200, so that the lubricating oil is sprayed upward on the track 200, and then spreads on the track 200 under the action of gravity.

[0066] Further, the top surface of the swing groove 102 is provided with a movable groove 103, the vertical section of the connecting rod 422 passes through the corresponding movable groove 103 and is fixed with the arc rod 421, the movable groove 103 and the swing groove 102 are provided for the swing structure 420 to move, the movable groove 103 is arc-shaped and matched with the curvature of the arc rod 421, the outer end of the oil outlet pipe 407 passes through the corresponding side arc rod 421 and is communicated with the corresponding nozzle 408, the part of the oil outlet pipe 407 between the oil suction pipe 405 and the oil storage tank 600 is a hard pipe, the part between the oil storage tank 600 and the arc rod 421 is a soft pipe, and the part between the arc rod 421 and the nozzle 408 is a hard pipe.

[0067] Specifically, the outer side wall of the arc rod 421 is fixed with an L-shaped plate 423, the outer side of the L-shaped plate 423 is fixed with a convex plate 424, and the middle rod wall of the rotating rod 401 is provided with an inward fixed plate 401a. When the rotating rod 401 rotates, the convex plate 424 is pushed by the fixed plate 401a to drive the arc rod 421 to rotate. Since the rotating directions of the two rotating rods 401 are opposite, the convex plate 424 on the inner arc rod 421 is fixed at the front side of the middle part of the inner L-shaped plate 423 in the counterclockwise direction, and the convex plate 424 on the outer arc rod 421 is fixed at the rear side of the middle part of the outer L-shaped plate 423 in the counterclockwise direction. When the inner rotating rod 401 rotates counterclockwise, the inner convex plate 424 is pushed to drive the whole swing structure 420 to swing, and then the nozzle 408 is swung to increase the oil injection range. When the inner rotating rod 401 rotates counterclockwise to separate from the inner convex plate 424, the swing structure 420 stops swinging. When the outer rotating rod 401 rotates counterclockwise, the outer convex plate 424 can still contact with the fixed plate 401a on the outer rotating rod 401 to drive the swing structure 420 to swing clockwise.

[0068] It should be noted that since the oil injection is frequent and the amount of oil injection is small each time, the required oil suction force and oil injection pressure are small, that is, the elastic force of the clock spring 402a is small. Therefore, when the cam 411 contacts with the top plate 412, the resistance of the cam 411 is small, which does not affect the sliding of the sliding plate 300. Meanwhile, the top plate 412, the mounting plate 414, the connecting rod 422, the swing groove 102 and the movable groove 103 in the lubricating assembly 400 can be paved with steel balls to reduce the friction between them, and further reduce the influence on the sliding plate 300 during oil injection.

[0069] In addition, the application also provides an application of the large-diameter multi-section arc guide rail assembly based on the high-speed precision gear transmission device, which comprises the large-diameter multi-section arc guide rail assembly based on the high-speed precision gear transmission device.

[0070] In the application, the specific working principle of the large-diameter multi-section arc guide rail assembly based on the high-speed precision gear transmission device is as follows:

[0071] When the convex part of the cam 411 contacts with the inner end of the top plate 412, the top plate 412 is squeezed inward, and the rotating rod 401 is pushed to rotate by the hinged rod 413 to drive the threaded rod 403 to rotate, and then the movable rod 404 is moved upward, so that the piston 404a moves upward to suck the lubricating oil in the oil storage barrel 600 into the oil suction pipe 405 through the one-way valve 406, and the rotating rod 401 rotates to deform the clock spring 402a to store energy.

[0072] When the slide plate 300 slides to the point that the cam 411 separates from the top plate 412, the clockwork spring 402a is released, which in turn drives the threaded rod 403 to rotate rapidly, causing the piston 404a to move down rapidly, thus ensuring that the lubricating oil has enough power to be sprayed from the nozzle 408 onto the track 200, thus achieving automatic oil spraying;

[0073] When the rotating rod 401 rotates, the convex plate 424 on the outer arc rod 421 is fixed to the rear side of the outer L-shaped plate 423 in the counterclockwise direction. When the inner rotating rod 401 rotates counterclockwise or the outer rotating rod 401 rotates counterclockwise, the entire swing structure 420 will swing by pushing the inner convex plate 424, thus causing the nozzle 408 to swing and increasing the oil spraying range.

[0074] The foregoing description of specific exemplary embodiments of the application is intended to be illustrative only and is not intended to limit the application to the precise forms described. Many modifications and variations are possible in light of the above teachings without departing from the spirit or essential characteristics of the application. The exemplary embodiments are chosen and described in order to explain the principles of the application and its practical application and to allow others skilled in the art to understand the application for various exemplary embodiments with various modifications being applicable. The scope of the application is intended to be defined by the claims and their equivalents.
