Description

Technical Field

[0001] This invention relates to the field of lifting and transportation technology, and in particular to a crane turntable tilting device, tilting control method and processing system. Background Technology

[0002] The turntable is an important structural component of a crane, serving to connect the frame and the boom. Mounted on a slewing bearing, the turntable can rotate around the base. Components such as the boom, tower, or A-frame can be installed on the turntable. The turntable not only bears the weight of all components above the crane's undercarriage traveling system and the suspended load, but also the bending moment generated by the suspended load and counterweight. Therefore, the turntable has a large volume and weight.

[0003] During the machining process, it is necessary to machine the flange holes on the bottom surface and the boom mounting holes and luffing cylinder mounting holes on the top surface. The turntable needs to be rotated up and down during the machining process. Due to the large size and weight of the turntable, it is difficult to rotate it manually. If tools such as hooks are used for rotation, there is a risk of it falling. If the turntable falls, it will damage the ground and the turntable, and it is very easy to cause safety accidents. The safety and reliability are poor. Summary of the Invention

[0007] In one embodiment, the front end of the side fixing member is provided with a second pressing member, the second pressing member extends in the left-right direction and is configured to move in the left-right direction to contact or move away from the side of the body. The two second pressing members cooperate to fix the body in the left-right direction.

[0008] In one embodiment, the base support is provided with a detection element, which is capable of detecting the pressure from the turntable on the base support in the vertical direction.

[0009] In one embodiment, the flipping mechanism further includes a drive unit, through which the two clamping arms are mounted on the machine body. The drive unit is used to drive the two clamping arms to move closer to or further away from each other in the left-right direction.

[0010] In one embodiment, the machine body is provided with a mounting frame, the flipping mechanism is connected to the machine body through the mounting frame, the mounting frame is mounted on the machine body through a rotating shaft, the mounting frame is rotatable around the rotating shaft to drive the flipping mechanism to rotate, and / or, the machine body is provided with a lifting plate, the flipping mechanism is mounted on the lifting plate, the lifting plate is configured to move relative to the machine body in the vertical direction to drive the flipping mechanism to rise and fall.

[0011] In one embodiment, the base support includes a first support beam, a second support beam, and an adjusting member. The first support beam is connected to the upper end of the second support beam and is used to contact the flange and cooperate with the first pressing member to fix the flange in the vertical direction. The detection member is disposed between the first support beam and the second support beam, and the adjusting member is used to adjust the relative position of the first support beam and the second support beam.

[0012] In one embodiment, the body includes a base, a support base, and a rotating base. The flipping mechanism is mounted on the support base, and the support base is mounted on the base via the rotating base. The rotating base is configured to rotate relative to the base to drive the support base to rotate.

[0013] The present invention also proposes a crane turntable tilting control method, applied to the above-mentioned crane turntable tilting device, comprising the following steps:

[0014] S1. Control the two clamping arms to move closer to each other in the left and right direction until they contact the left and right sides of the body, thereby fixing the body in the left and right direction and fixing the flange in the up and down direction.

[0015] S2. Based on the need for the turntable to be flipped, the two clamping arms rotate 180° relative to the machine body, causing the turntable to flip up and down.

Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. Based on the description of the present invention, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the present invention.

[0036] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar properties, not to indicate or imply relative importance or a specific order.

[0037] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0038] The turntable is an important structural component of a crane, serving to connect the frame and the boom. Mounted on a slewing bearing, the turntable can rotate around its base. The boom, tower, or A-frame, as well as various winches and slewing mechanisms, can be installed on the turntable. The turntable not only bears the weight of all components above the crane's undercarriage traveling system and the suspended load, but also the bending moment generated by the suspended load and counterweight. Therefore, the turntable has a large volume and weight.

[0039] During the machining process, it is necessary to machine the flange holes on the bottom surface and the boom mounting holes and luffing cylinder mounting holes on the top surface. The turntable needs to be rotated up and down during the machining process. Due to the large size and weight of the turntable, it is difficult to rotate it manually. If tools such as hooks are used for rotation, there is a risk of it falling. If the turntable falls, it will damage the ground and the turntable, and it is very easy to cause safety accidents. The safety and reliability are poor.

[0040] like Figure 1 As shown, the crane turntable tilting device proposed in this invention is used to fix and tilt the turntable 30. The turntable 30 includes a body 31 and flanges 32 located on the lower left and right sides of the body 31. The flanges 32 are used to connect the turntable 30 to other components. The entire turntable tilting device includes a body 10, on which a tilting mechanism 20 is mounted. The tilting mechanism 20 is used to support the turntable 30 and, in conjunction with… Figure 2 The flipping mechanism 20 includes two clamping arms 201, which are opposite each other in the left-right direction. The two clamping arms 201 can fix the body 31 in the left-right direction and fix the flange 32 in the left-right and up-down directions. The two clamping arms 201 are configured to move closer to each other or further away in the left-right direction. When the two clamping arms 201 move closer to each other, they can clamp and fix the turntable 30. When the two clamping arms 201 move further away from each other, they can release the turntable 30. The flipping mechanism 20 is configured to rotate relative to the body 10 so that the turntable 30 can be flipped up and down.

[0041] The flipping mechanism 20 is configured to rotate relative to the machine body 10. By changing the angle of the flipping mechanism 20, the angle of the turntable 30 can be changed, allowing the upper and lower end faces of the turntable 30 to be interchanged. This enables it to be used in conjunction with other processing equipment to process the upper and lower ends of the body 31. The two clamping arms 201 can clamp and fix the turntable 30 in the left-right and up-down directions, ensuring the stability of the turntable 30 during the flipping process. This eliminates the need for a large amount of manpower to flip the turntable 30, thus eliminating the risk of the turntable 30 falling and improving safety. The two clamping arms 201 are configured to move closer to or further away from each other in the left-right direction. The travel of the two clamping arms 201 can be adjusted according to the different sizes of the turntable 30, thereby achieving the fixation of turntables 30 of different sizes and providing good applicability.

[0042] As an optional embodiment, the two clamping arms 201 extend in the front-to-back direction, and their rear ends are connected to the body 10, and they are symmetrical in the left-to-right direction, as shown below. Figure 3 As shown, the clamping arm 201 includes a side fixing member 21, a bottom support member 22, and a first pressing member 23. The side fixing member 21 is used to contact the side of the body 31. The side fixing members 21 of the two clamping arms 201 cooperate to clamp and fix the left and right sides of the body 31. The bottom support member 22 is arranged below the side fixing member 21, and there is a fixing space between the bottom support member 22 and the side fixing member 21 to accommodate the flange 32. The bottom support member 22 is used to contact the lower end of the flange 32 to support the flange 32. The first pressing member 23 is connected to the lower end of the side fixing member 21 and is positioned corresponding to the bottom support member 22. This positional correspondence means that the position of the first pressing member 23 enables it to cooperate with the bottom support member 22 to fix the flange 32 together. The first pressing member 23 is configured to be able to move relative to the bottom support member 22 in the vertical direction. The first pressing member 23 cooperates with the bottom support member 22 to clamp and fix the flange 32 in the vertical direction.

[0043] In one example of this embodiment, the rear end of the side fixing member 21 is used for connection with the body 10, such as... Figure 3 As shown, the rear end of the side fixing member 21 is provided with a connecting end member 211, and the side fixing member 21 can be connected to the body 10 through the connecting end member 211.

[0044] In one alternative, the connecting end piece 211 and the side fixing piece 21 are integrally formed, for example, they can be formed into one piece directly by casting or other processes. In another alternative, the connecting end piece 211 and the side fixing piece 21 are separately formed, and the two are fixedly connected, for example, they can be connected as an inseparable whole by welding or other methods, or the two can be detachably connected, for example, by screwing.

[0045] In one example of this embodiment, a detection element is provided on the base support 22. The detection element can detect the pressure from the turntable 30 on the base support 22 in the vertical direction. More specifically, the detection element can detect the force exerted on the base support 22 by the weight of the turntable 30, so as to ensure that the pressure exerted on the flange 32 by the first pressing element 23 is not too large and damages the flange 32. This can avoid the problem of wear and deformation of the turntable 30 due to excessive clamping during the fixing process.

[0046] Optionally, the testing element may be a weighing sensor or a pressure sensor.

[0047] In one example of this embodiment, when the detection element is a weighing sensor, refer to Figure 3 The base support 22 includes a first support beam 221, a second support beam 222, and an adjusting member. The first support beam 221 is connected to the upper end of the second support beam 222. The upper end of the first support beam 221 is used to contact the flange 32 and cooperate with the first pressing member 23 to fix the flange 32 in the vertical direction. The detection member is located between the first support beam 221 and the second support beam 222 to measure the change of the force exerted by the first support beam 221 on the second support beam 222. The adjusting member is used to cooperate with the detection member and can adjust the relative position of the first support beam 221 and the second support beam 222.

[0048] Optionally, the adjusting component includes a mounting plate 223 and an adjusting cam 224. The mounting plate 223 is connected to the left and right sides of the second support beam 222 and extends upward to the left and right sides of the first support beam 221. The adjusting cam 224 is mounted on the mounting plate 223 and is positioned on the left and right sides of the first support beam 221. By adjusting the position and angle of the adjusting cam 224, a force is applied to the first support beam 221, thereby clamping the first support beam 221 and the second support beam 222 together.

[0049] Since the weighing sensor has a preset up and down stroke during operation, the change of this stroke will cause the gap between the first support beam 221 and the second support beam 222 to change. By adjusting the adjustment component, the gap between the first support beam 221 and the second support beam 222 can be avoided, thereby avoiding the problem of the first support beam 221 shaking or swaying when the fixed flange 32 is fixed, which is conducive to ensuring the rotation efficiency of the turntable 30.

[0050] In an alternative embodiment, the adjusting cam 224 employs a cam bearing follower.

[0051] In one example of this embodiment, the first pressing member 23 is connected to the lower end of the side fixing member 21 via a cylinder or a hydraulic vertical cylinder, and the first pressing member 23 is connected to the output rod of the cylinder or the hydraulic vertical cylinder.

[0052] In one example of this embodiment, the number of first pressure members 23 is configured to be at least one, and further, as... Figure 3 As shown, the number of first pressing members 23 is set to three, and they are distributed at intervals along the front and rear direction, which can be used to fix turntables 30 of different sizes. The three first pressing members 23 are configured to move synchronously to cooperate with the bottom support member 22 to fix the flange 32 in the vertical direction with high quality, so that the turntable 30 is relatively stationary with the clamping arm 201 during the vertical flipping process, avoiding the turntable 30 from shaking and causing wear and collision during the flipping process, and preventing the turntable 30 from falling off the clamping arm 201.

[0053] In this example of Embodiment 1, as Figure 3 As shown, a protective member 24 is provided on the side of the side fixing member 21 near the turntable 30. The protective member 24 is used to directly contact the side of the body 31. The protective member 24 can protect the end face of the turntable 30 to avoid damage to the end face of the turntable 30 during the clamping and fixing process.

[0054] Optionally, the protective component 24 can be made of rubber pads, silicone pads, resin pads, etc., which can not only provide protection, but also increase the coefficient of friction between the side fixing component 21 and the body 31, thus improving the fixing effect.

[0055] In one example of this embodiment, the bottom support 23 is provided with the aforementioned protective member 24 at one end near the flange 32. Those skilled in the art can adjust the size, shape, and other parameters of the protective member 24 according to actual needs and its placement.

[0056] In one example of this embodiment, the end of the first pressing member 23 that contacts the flange 32 is provided with the aforementioned protective member 24. Those skilled in the art can adjust the size, shape, and other parameters of the protective member 24 according to actual needs and its placement.

[0057] As an optional implementation method, such as Figure 3 As shown, the front end of the side fixing member 21 is provided with a second pressing member 25. The second pressing member 25 extends in the left and right direction. The second pressing member 25 is configured to be able to move in the left and right direction relative to the side fixing member 21 to contact or move away from the side of the body 31. The second pressing members 25 of the two clamping arms 201 cooperate to clamp and fix the body 31 in the left and right direction.

[0058] Because the turntable 30 has an irregular shape, it is usually difficult to fix it, and it is easy to slip during the fixing and clamping process. The second clamping member 25 can play a supplementary fixing role. It is only necessary to find a suitable fixing point on the side of the main body 31 for the second clamping member 25 to contact. Moreover, the second clamping member 25 is set on the side fixing member 21 and can move synchronously with the side fixing member 21 relative to the machine body 10. It will not increase the time required for clamping and fixing, which helps to improve the stability of the turntable 30 in the left and right directions.

[0059] Optionally, the second pressing member 25 is connected to the front end of the side fixing member 21 via a cylinder or a hydraulic horizontal cylinder, and the second pressing member 25 is connected to the output rod of the cylinder or the hydraulic horizontal cylinder.

[0060] Optionally, the end of the second pressing member 25 that contacts the body 31 is provided with the aforementioned protective member 24. Those skilled in the art can adjust the size, shape, and other parameters of the protective member 24 according to actual needs and its placement.

[0061] As an optional implementation method, such as Figure 2 As shown, the flipping mechanism 20 also includes a drive unit 26. Two clamping arms 201 are mounted on the body 10 via the drive unit 26. The drive unit 26 is used to drive the two clamping arms 201 to move closer or further apart in the left and right directions.

[0062] Optionally, the drive unit 26 is configured to drive the two clamping arms 201 to move synchronously.

[0063] In one of the alternative solutions, such as Figure 2 As shown, the drive unit 26 includes a carrier chain 261 and a drive wheel that is connected to the carrier chain 261. The drive wheel can rotate around its own axis to cooperate with the carrier chain 261 to drive the two clamping arms 201 to move synchronously in the left and right directions. By configuring the two clamping arms 201 to move synchronously, the turntable 30 can be positioned in the center when it is fixed, so as not to cause positional skew and affect the fixing effect.

[0064] In another alternative, the drive unit 26 includes a rack and a gear connected to the rack. A drive member drives the gear to rotate around its own axis. The gear meshes with the rack to drive the two clamping arms 201 to move synchronously in the left and right directions.

[0065] As an optional implementation method, such as Figure 2 As shown, the body 10 is provided with a mounting bracket 11, and the flipping mechanism 20 is connected to the body 10 through the mounting bracket 11. More specifically, the drive unit 26 is connected to the body 10 through the mounting bracket 11. The mounting bracket 11 is mounted on the front end of the body 10 through a rotating shaft, and the mounting bracket 11 can rotate relative to the body 10 around the axis of the rotating shaft, thereby driving the flipping mechanism 20 to rotate relative to the body 10.

[0066] In one alternative, the mounting bracket 11 is configured to rotate 180° axially around the pivot and to achieve both forward and reverse rotation. Taking the upper end face of the turntable 30 as an example, when the mounting bracket 11 rotates 180° forward, the turntable 30 flips to the lower end face. At this time, when the mounting bracket 11 rotates 180° in the reverse direction, the turntable 30 flips to the upper end face (i.e., resets).

[0067] In another alternative, the mounting bracket 11 is configured to rotate 360° around the axis of rotation, and can only rotate in one direction. Taking the upper end face of the turntable 30 as an example, when the mounting bracket 11 rotates 180° in the forward direction, the turntable 30 flips to the lower end face. At this time, when the mounting bracket 11 continues to rotate 180° in the same direction, the turntable 30 flips to the upper end face (i.e., reset).

[0068] As an optional implementation method, combined with Figure 1 and Figure 3 A lifting plate 12 is installed on the body 10. The flipping mechanism 20 and the mounting frame 11 are installed on the lifting plate 12 and are installed on the body 10 through the lifting plate 12. The lifting plate 12 is configured to move in the vertical direction relative to the body 10 to drive the flipping mechanism 20 and the mounting frame 11 to rise and fall. The height and position of the two clamping arms 201 can be adjusted according to the different sizes of the turntable 30 and the storage position of the turntable 30, so as to meet different fixing and flipping requirements.

[0069] In one alternative embodiment, the front end of the body 10 is provided with a slide rail 13, which extends vertically. The lifting plate 12 is slidably connected to the slide rail 13 to move vertically relative to the slide rail 13. In another alternative embodiment, the lifting plate 12 and the slide rail 13 are connected by a gear and rack transmission assembly. A driving component drives the gear to rotate around its own axis. The meshing transmission between the gear and the rack can drive the lifting plate 12 to move vertically along the slide rail 13.

[0070] As an optional implementation method, combined with Figure 1 and Figure 4 The machine body 10 is mounted on the guide rail 101 so that it can move along the guide rail 101 to grab, fix and flip the turntable 30 from its storage location, and transport the turntable 30 along the guide rail 101 to the processing equipment for processing. The lower part of the machine body 10 is provided with a track fitting 14, which is used to cooperate with the guide rail 101 so that the machine body 10 can move along the guide rail 101.

[0071] Optionally, the guide rail 101 is provided with a sliding contact line connected to an external power source, and the rail fitting 14 adopts a brush that cooperates with the sliding contact line. The brush is slidably connected to the sliding contact line so that the machine body 10 can move along the guide rail 101.

[0072] In one example of this embodiment, such as Figure 4 As shown, the lower part of the body 10 is provided with a control component 15, which can cooperate with the guide rail 101 to monitor and determine the position of the body 10 on the guide rail 101 in real time.

[0073] Optionally, the control unit 15 adopts a barcode scanner, and the guide rail 101 is provided with a position barcode indicating the position. When the machine body 10 moves along the guide rail 101 to the point where the barcode scanner can scan the position barcode, the position of the machine body 10 can be determined. The position barcode can be set according to the location of the processing equipment so that the machine body 10 can automatically move to the processing equipment to process the turntable 30.

[0074] In one example of this embodiment, such as Figure 4 As shown, the machine body 10 includes a base 16, a support base 17, and a rotating base 18. The support base 17 is mounted on the base 16 via the rotating base 18. The rotating base 18 is configured to rotate relative to the base 16, thereby causing the support base 17 to rotate relative to the base 16. The flipping mechanism 20, the mounting bracket 11, and the lifting plate 12 are all mounted on the support base 17. By rotating the support base 17 relative to the base 16, the angle of the flipping mechanism 20 relative to the base 16 can be changed, thereby enabling the flipping mechanism 20 to conveniently adjust its angle according to the position of the turntable 30 and the position of the processing equipment, so as to facilitate the loading and unloading of the turntable 30.

[0075] Optionally, the support 17 is configured to rotate 360° relative to the base 16.

[0076] As an optional embodiment, the machine body 10 is also equipped with a central control screen to display data in real time, such as the height and angle of the two clamping arms 201, the detection data of the detection components, etc., which is conducive to realizing intelligent control and is more intuitive. Commands can also be issued through the central control screen to adjust the height and angle of the two clamping arms 201, the trigger value of the prompt signal of the detection components, etc.

[0077] like Figure 5 As shown, the present invention also proposes a crane turntable tilting control method, applied to the above-mentioned crane turntable tilting device, specifically including the following steps:

[0078] S1. Control the two clamping arms 201 to move closer to each other in the left and right directions until they contact the left and right sides of the body 31, and fix the body 31 in the left and right directions. The two clamping arms 201 fix the flange 32 in the up and down directions.

[0079] S2. Since the turntable 30 needs to be flipped, the two clamping arms 201 rotate 180° relative to the machine body 10, so that the turntable 30 flips up and down.

[0080] As an optional embodiment, step S1 above further includes:

[0081] S1.1 When the two clamping arms 201 approach each other in the left and right direction, until the two side fixing parts 21 contact the left and right sides of the body 31, the flanges 32 on both sides of the body 31 are located at the upper end of the bottom support 22, and the two clamping arms 201 stop moving.

[0082] As an optional embodiment, step S1 above further includes:

[0083] S1.2 The first pressing member 23 moves downward until it contacts the upper end of the flange 32 until the detection member issues a prompt signal. The first pressing member 23 receives the prompt signal and stops moving. In this step, the pressure (or weight) borne by the base support 22 is measured by the detection member, and a prompt signal is issued when the detected value reaches the preset value. The detection member issues a prompt signal to control the movement stroke of the first pressing member 23. While ensuring the fixing effect, it also ensures that the first pressing member 23 does not clamp excessively and damage the flange 32.

[0084] As an optional embodiment, step S1 above further includes:

[0085] S1.3 The two second pressing members 25 move closer to each other in the left and right direction until they contact the left and right sides of the body 31 and clamp the body 31 in the left and right direction; in this step, the turntable 30 can be fixed at multiple points in the left and right direction by the cooperation of the second pressing members 25 and the side fixing members 21.

[0086] As an optional embodiment, step S1 above further includes:

[0087] S1.01. Based on the position and height of the turntable 30, the lifting plate 12 moves vertically relative to the machine body 10, adjusting the height of the flipping mechanism 20 so that the positions of the two clamping arms 201 correspond to the position of the turntable 30. In this step, the place where the turntable 30 is placed can be a processing equipment that has already finished processing. For example, after the upper end face of the turntable 30 is processed, it needs to be flipped by the flipping mechanism 20 so that its lower end face can be processed by another processing equipment. At this time, the aforementioned processing equipment that has already finished processing is the processing equipment used to process the upper end face of the turntable 30. The place where the turntable 30 is placed can also be a storage place before processing.

[0088] As an optional embodiment, step S1 above further includes:

[0089] S1.02. Based on the position of the turntable 30, the support base 17 rotates relative to the base 16 so that the angle of the flipping mechanism 20 corresponds to the position of the turntable 30. In this step, the turntable 30 can be placed at a processing equipment that has already finished processing, or at a storage location before processing.

[0090] As an optional embodiment, the crane turntable tilting control method proposed in this invention includes the following steps:

[0091] S1.01. Based on the position and height of the turntable 30, the lifting plate 12 moves in the vertical direction relative to the machine body 10, and the height of the flipping mechanism 20 is adjusted so that the positions of the two clamping arms 201 correspond to the positions of the turntable 30.

[0092] S1.02. Based on the position of the turntable 30, the support base 17 rotates relative to the base 16 so that the angle of the flipping mechanism 20 corresponds to the position of the turntable 30.

[0093] S1. Control the two clamping arms 201 to move closer to each other in the left and right direction until the two side fixing parts 21 contact the left and right sides of the body 31, the flanges 32 on both sides of the body 31 are located at the upper end of the bottom support 22, and the two clamping arms 201 stop moving.

[0094] The first pressing member 23 moves downward until it contacts the upper end of the flange 32, until the detection member issues a prompt signal. The first pressing member 23 receives the prompt signal and stops moving.

[0095] The two second pressing members 25 move closer to each other in the left and right direction until they contact the left and right sides of the body 31 and clamp the body 31 in the left and right direction;

[0096] S2. Since the turntable 30 needs to be flipped, the two clamping arms 201 rotate 180° relative to the machine body 10, so that the turntable 30 flips up and down.

[0097] Based on the aforementioned crane turntable tilting device, this invention also proposes a crane turntable processing system, such as... Figure 6 As shown, it includes:

[0098] The guide rail 101 is provided, and the body 10 is movably mounted on the guide rail 101 and can move along the extension direction of the guide rail 101.

[0099] The top surface processing device 102 is located on one side of the guide rail 101 and is used to process the upper surface of the turntable 30.

[0100] The bottom surface processing device 103 is located on one side of the guide rail 101 and is used to process the lower end surface of the turntable 30. The bottom surface processing device 103 and the top surface processing device 102 are located on the same side of the guide rail 101 or on both sides of the guide rail 101.

[0101] As an optional embodiment, the top surface processing device 102 is used to perform a drilling operation on the upper end surface of the turntable 30 to process boom mounting holes and luffing cylinder mounting holes on the upper end surface of the turntable 30.

[0102] As an optional embodiment, the bottom surface processing device 103 is used to perform a drilling operation on the lower end face of the turntable 30 to process flange holes on the lower end face of the turntable 30.

[0103] As an optional implementation method, such as Figure 6 As shown, the guide rail 101 extends in the front-to-back direction. The top surface processing device 102 and the bottom surface processing device 103 are located on both sides of the guide rail 101 in the left-to-right direction. The machine body 10 moves relative to the guide rail 101 to the top surface processing device 102 to transport the upper end face of the turntable 30 to the top surface processing device 102 for processing. After processing, the turntable 30 is flipped up and down. At the same time, the rotation angle of the support base 17 causes the flipping mechanism 20 to rotate to the side away from the top surface processing device 102. Then, the lower end face of the turntable 30 is transported to the bottom surface processing device 103 for processing.

[0104] Understandably, the above processing sequence, as well as the order of flipping and rotating, can be adjusted according to actual needs and does not necessarily have to be followed in this order.

[0105] Optionally, the top surface processing device 102 and the bottom surface processing device 103 are symmetrically arranged on both sides of the guide rail 101. After the upper surface is processed, the support base 17 rotates 90°, the flipping mechanism 20 flips the turntable 30, the support base 17 rotates 90° again, and the turntable 30 is sent to the bottom surface processing device 103.

[0106] As an optional embodiment, the guide rail 101 extends in the front-to-back direction, and the top surface processing device 102 and the bottom surface processing device 103 are located on the same side of the guide rail 101 in the left-to-right direction. The machine body 10 moves relative to the guide rail 101 to the top surface processing device 102 to transport the upper end face of the turntable 30 to the top surface processing device 102 for processing. After processing is completed, the support base 17 rotates, the flipping mechanism 20 flips the turntable 30 up and down, and then it moves along the guide rail 101 to the bottom surface processing device 103 for processing.

[0107] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
