Description

Technical Field

[0001] This invention belongs to the field of supporting rotating platforms, and particularly relates to a supporting rotating platform for mechanical components. Background Technology

[0002] Rotary support platforms are used to support various mechanical components and provide them with stable support and flexible rotation functions. Compared with mechanical contact type rotary platforms, hydrostatic type rotary platforms use pressure oil film as working medium, which has high load-bearing rigidity characteristics, no wear between friction pairs, and sensitive and stable operation.

[0003] During the rotation of the supporting rotating platform, the injection pipe injects lubricating oil between the top of the supporting platform and the rotating platform to form an oil film. The resulting hydrostatic pressure can support the rotating platform and reduce the coefficient of friction. However, the lubricating oil is difficult to distribute evenly in the gap between the rotating platform and the supporting platform, which increases wear. In addition, excess lubricating oil will continuously overflow and flow into the frame below the supporting rotating platform, making it difficult to effectively recycle and reuse the lubricating oil, thus increasing the waste of lubricating oil. Summary of the Invention

[0004] In order to solve the problems mentioned in the background art, the present invention provides a support rotary platform for mechanical components that can effectively recycle lubricating oil.

[0005] The technical implementation of the present invention is as follows: A supporting rotating platform for mechanical components includes a bracket, a mounting frame with an internal mounting cavity connected to the top of the bracket, an oil storage frame with an internal oil storage cavity connected to the top of the mounting frame, an oil inlet pipe installed on the side of the oil storage frame, a rotating shaft rotatably connected to the top of the mounting frame, a rotating platform connected to the top of the rotating shaft, a supporting platform located below the rotating platform connected to the top of the oil storage frame, a fixed plate connected to the upper side inside the supporting platform, an oil inlet hole and a return hole opened on the fixed plate, an oil passage pipe communicating between the bottom of the oil storage frame and the oil inlet hole, and a return pipe extending into the oil storage cavity communicating at the bottom of the return hole of the fixed plate.

[0006] Furthermore, the supporting rotating platform for mechanical components also includes a drive mechanism for driving the rotating shaft to rotate. The drive mechanism includes a drive motor and a gear set. The drive motor is connected inside the mounting frame, and the output shaft of the drive motor is transmitted to the rotating shaft through the gear set.

[0007] Furthermore, the top of the fixed plate has a small annular portion and a large annular portion, with an oil inlet area formed between the small annular portion and the large annular portion, and an oil inlet hole located in the oil inlet area. A reflux area is formed between the large annular portion and the inner wall of the support platform, and a reflux hole is located in the reflux area.

[0008] Furthermore, the support platform has an annular groove in the middle of its top, and a ring of evenly spaced circular holes in the annular groove, which are connected to the oil inlet area. The annular groove extends outward to form a ring of spaced radial grooves, and multiple arc-shaped channels connected to the return flow area are opened circumferentially at the top edge of the support platform.

[0009] Furthermore, the rotating support platform for mechanical components also includes a support base, the support base is connected inside the oil storage frame, a filter frame is placed inside the oil storage frame, the return pipe is located directly above the filter frame, a rotating hook is rotatably connected to the side of the filter frame, and a limit block is connected to the outer wall of the oil storage frame, with the rotating hook hooking the limit block.

[0010] Furthermore, the supporting rotating platform for mechanical components also includes a round block. The top of the oil storage frame is connected to the round block, and the top of the oil storage frame is equipped with a sliding baffle. An elastic element connects the baffle and the round block. The filter frame abuts against the baffle, and the sliding of the baffle will block the bottom end of the return pipe.

[0011] Furthermore, the supporting rotating platform for mechanical components also includes a rotating blocking ring. The rotating blocking ring is rotatably connected to the upper part of the side wall of the supporting platform. The lower side of the inner wall of the rotating blocking ring has an inclined edge. A ring of evenly spaced vertical blocks is connected circumferentially to the inner wall of the rotating blocking ring. A connecting rod is connected to the outer wall of the rotating blocking ring. The connecting rod has an elongated hole. A guide rail is connected to the top of the oil storage frame. A sliding slide rod is provided on the guide rail. A return spring is connected between the slide rod and the guide rail. The slide rod is located inside the elongated hole.

[0012] Furthermore, the supporting rotating platform for mechanical components also includes an arc-shaped rack, the outer wall of the rotating blocking ring is connected to the arc-shaped rack, a rotating rod is rotatably connected to the oil reservoir, and a missing gear that meshes with the arc-shaped rack is connected to the rotating rod. The rotating rod and the rotating shaft are driven by a pulley assembly.

[0013] The present invention has the following advantages: 1. The lubricating oil in the oil storage frame flows into the oil inlet area through the oil pipe. The lubricating oil enters the annular groove and diffuses in multiple directions through the radial groove to the gap between the bottom surface of the rotating platform and the top surface of the support platform. The lubricating oil forms a uniformly distributed oil film. When the rotating shaft and the rotating platform rotate, the lubricating oil flows into the return area through the arc-shaped channel. The lubricating oil in the return area flows back to the oil storage cavity through the return pipe, thereby effectively recycling the lubricating oil.

[0014] 2. The filter frame filters the returned lubricating oil. By pushing the rotating hook to rotate, the rotating hook is no longer hooked on the limit block, and the filter frame is pulled out for cleaning. The elastic element returns to its original state so that the baffle slides. The baffle blocks the bottom of the return pipe to prevent unfiltered lubricating oil from flowing directly into the oil storage chamber. Then, the filter frame is pushed in and the rotating hook is pushed. The rotating hook hooks on the limit block to limit the filter frame.

[0015] 3. When the lubricating oil flows down into the return zone through the arc-shaped channel, the rotating blocking ring prevents the lubricating oil from flowing to the outside of the support platform. The pulley assembly drives the rotating shaft to rotate the rotating rod and the missing gear. The missing gear intermittently meshes with the arc-shaped rack. With the cooperation of the connecting rod, the sliding rod and the return spring, the rotating blocking ring rotates back and forth, which promotes the lubricating oil on the inner wall of the rotating blocking ring to flow into the arc-shaped channel, reducing the residue of lubricating oil.

[0028] A rotating support platform for mechanical components, such as Figures 1-7 As shown, the system includes a bracket 1, a mounting frame 2, an oil storage frame 3, an oil inlet pipe 30, a rotating shaft 4, a rotating platform 5, a support platform 6, a fixed plate 7, an oil passage pipe 8, a liquid pump 80, and a return pipe 9. The top of the bracket 1 is connected to the mounting frame 2, which has an internal mounting cavity. The top of the mounting frame 2 is connected to the oil storage frame 3, which has an internal oil storage cavity. The oil inlet pipe 30 is installed on the front right side of the oil storage frame 3, and a one-way valve is installed on the oil inlet pipe 30. The top of the mounting frame 2 is rotatably connected to the rotating shaft 4, and the top of the rotating shaft 4 is fixedly connected to the rotating platform 5. The top of the oil storage frame 3 is connected to the support platform 6, which is located below the rotating platform 5. The upper side of the support platform 6 is fixedly connected to the inside of the support platform 6. The rotating shaft 4 passes through the center of the fixed plate 7. The fixed plate 7 has one oil inlet hole 81 and two return holes 90. The bottom of the oil storage frame 3 is connected to the oil inlet hole 81. There is an oil passage pipe 8, on which a liquid pump 80 is installed. The one-way valve and the liquid pump 80 are specific to existing technology. The fixed plate 7 is connected to a return pipe 9 extending into the oil storage chamber at the bottom of the return hole 90. The top of the fixed plate 7 has a small annular part 71 and a large annular part 72. An oil inlet area is formed between the small annular part 71 and the large annular part 72. The oil inlet hole 81 is located in the oil inlet area. A return area is formed between the outer periphery of the large annular part 72 and the inner side wall of the support platform 6. The return hole 90 is located in the return area. An annular groove 62 is opened in the middle of the top of the support platform 6. Four evenly spaced circular holes 61 are opened in the annular groove 62 of the support platform 6. The circular holes 61 are connected to the oil inlet area. The annular groove 62 extends outward to form eight evenly spaced radial grooves 63. Six arc-shaped channels 64 connected to the return area are opened circumferentially at the top edge of the support platform 6.

[0029] like Figure 3 and Figure 4As shown, the supporting rotating platform for mechanical components also includes a drive mechanism for driving the rotating shaft 4 to rotate. The drive mechanism includes a drive motor 41 and a gear set 42. The drive motor 41 is bolted to the mounting frame 2 in the mounting cavity. The output shaft of the drive motor 41 is transmitted to the bottom end of the rotating shaft 4 through the gear set 42.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 9 As shown, the mechanical component support rotating platform also includes a support base 101, a filter frame 102, a rotating hook 103, and a limiting block 104. Two symmetrical support bases 101 are fixedly connected to the left side of the inside of the oil storage frame 3. The filter frame 102, supported by the support bases 101, is placed on the upper side of the inside of the oil storage frame 3. Both return pipes 9 are located directly above the filter frame 102. The rotating hook 103 is rotatably connected to the left side of the filter frame 102. The limiting block 104 is fixedly connected to the outer wall of the left side of the oil storage frame 3. The rotating hook 103 hooks the limiting block 104.

[0031] like Figure 3 , Figure 4 , Figure 8 and Figure 9 As shown, the supporting rotating platform for the mechanical components also includes round blocks 111, baffles 112, and elastic elements 113. Two pairs of round blocks 111 are fixedly connected to the top of the oil storage frame 3. Two baffles 112 that slide left and right are provided at the top of the oil storage frame 3. Elastic elements 113 are fixedly connected between the two baffles 112 and the two pairs of round blocks 111. The elastic element 113 is specifically a tension spring. The right side of the filter frame 102 abuts against the left side of the baffle 112. When the filter frame 102 is pulled out, the baffle 112 will slide to the left under the action of the elastic element 113 to block the bottom end of the return pipe 9.

[0032] like Figure 1 , Figure 2 , Figure 7 , Figure 10 and Figure 11 As shown, the supporting rotating platform for mechanical components also includes a rotating blocking ring 121, a vertical block 123, a connecting rod 124, a guide rail 125, and a sliding rod 126. The rotating blocking ring 121 is rotatably connected to the upper part of the side wall of the supporting platform 6. The lower side of the inner wall of the rotating blocking ring 121 has an inclined edge 122. A ring of evenly spaced vertical blocks 123 is fixedly connected to the inner wall of the rotating blocking ring 121 in the circumferential direction. The connecting rod 124 is fixedly connected to the outer wall of the rotating blocking ring 121. The connecting rod 124 has an elongated hole. The top of the oil storage frame 3 is fixedly connected to the guide rail 125. The guide rail 125 is provided with a sliding rod 126. A return spring is fixedly connected between the sliding rod 126 and the guide rail 125. The top of the sliding rod 126 is located in the elongated hole.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 10 and Figure 11 As shown, the supporting rotating platform for mechanical components also includes an arc-shaped rack 131, a rotating rod 132, a missing gear 133, and a pulley assembly 134. The arc-shaped rack 131 is fixedly connected to the outer wall of the rotating blocking ring 121. The rotating rod 132 is rotatably connected to the top of the oil reservoir 3. The missing gear 133, which meshes with the arc-shaped rack 131, is fixedly connected to the top of the rotating rod 132. The lower end of the rotating rod 132 and the rotating shaft 4 are driven by the pulley assembly 134.

[0034] First, lubricating oil is added to the oil reservoir 3 through the oil inlet pipe 30. The hydraulic pump 80 is controlled so that the lubricating oil in the oil reservoir 3 flows into the oil inlet area above the fixed plate 7 through the oil pipe 8 and the oil inlet hole 81. The lubricating oil in the oil inlet area then enters the annular groove 62 through the round hole 61. The lubricating oil in the annular groove 62 diffuses in multiple directions through the radial groove 63 to the gap between the bottom surface of the rotating platform 5 and the top surface of the support platform 6, forming a uniformly distributed oil film. Under the transmission action of the gear set 42, the drive motor 41 is controlled to drive the rotating shaft 4 to rotate, thereby driving the rotating platform 5 to rotate. The lubricating oil in the gap between the bottom surface of the rotating platform 5 and the top surface of the support platform 6 plays a supporting role and reduces the coefficient of friction.

[0035] During the rotation of the rotating platform 5, the lubricating oil in the gap gradually flows down through the arc-shaped channel 64 into the return zone above the fixed plate 7. The lubricating oil in the return zone flows back to the oil storage chamber of the oil storage frame 3 through the return hole 90 and the return pipe 9, thereby effectively recycling the lubricating oil.

[0036] Initially, the elastic element 113 is in a deformed state. When the lubricating oil in the return zone flows back to the oil storage chamber of the oil storage frame 3, the filter frame 102 filters the returned lubricating oil to remove impurities. After the rotating platform 5 finishes working, the rotating hook 103 is manually pushed to rotate, so that the rotating hook 103 no longer hooks the limit block 104, and the filter frame 102 can be pulled out to clean the impurities inside the filter frame 102. After the filter frame 102 is pulled out, the filter frame 102 no longer... When the baffle 112 is squeezed, the elastic element 113 returns to its original state, causing the baffle 112 to slide to the left. The baffle 112 blocks the bottom end of the return pipe 9, preventing unfiltered lubricating oil in the return pipe 9 from flowing directly into the oil storage chamber. After cleaning, the filter frame 102 is pushed into the support seat 101. The filter frame 102 squeezes the baffle 112, causing the baffle 112 to slide to the right. The elastic element 113 deforms, pushing the rotating hook 103 to rotate, so that the rotating hook 103 hooks the limiting block 104, thereby limiting the filter frame 102.

[0037] When the lubricating oil in the gap flows down into the return zone through the arc-shaped channel 64, the rotating blocking ring 121 prevents the lubricating oil from flowing to the outside of the support platform 6. Simultaneously with the rotation of the rotating shaft 4, the shaft 4 drives the rotating rod 132 and the missing gear 133 to rotate together via the transmission of the pulley assembly 134. The missing gear 133 intermittently meshes with the arc-shaped rack 131. When the missing gear 133 meshes with the arc-shaped rack 131, the rotating missing gear 133 causes the arc-shaped rack 131, the rotating blocking ring 121, and the connecting rod 124 to rotate together. The connecting rod 124 pushes the sliding rod 126 along... As the guide rail 125 slides forward, the return spring deforms. When the missing gear 133 separates from the arc rack 131, the return spring returns to its original state, causing the slide rod 126 to slide backward along the guide rail 125. The slide rod 126 pushes the connecting rod 124, causing the connecting rod 124, the rotating blocking ring 121, and the arc rack 131 to rotate in the opposite direction and reset together. During this process, the rotating blocking ring 121 rotates back and forth due to the action of the return spring. With the cooperation of the vertical block 123, the lubricating oil on the inner wall of the rotating blocking ring 121 flows downward into the arc channel 64, reducing the residue of lubricating oil.
