A polishing device for the production of wind power generation blades

Abstract

The invention discloses a polishing device for producing wind power generation blades, which belongs to the technical field of wind power generation blade processing. The device comprises a supporting unit, a polishing unit, a shifting unit and an unlocking unit. Four transposition rollers of the shifting unit correspond to four processing stations. When a shifting motor drives a first half gear to rotate, the four transposition rollers complete position switching and change the processing position in the process of the first half gear meshing with a positioning gear ring. When the first half gear is not meshing with the positioning gear ring, the second half gear drives the positioning gear to rotate, drives the positioning gear located at the polishing position to rotate, the positioning gear drives the adjusting roller to rotate, and the adjusting roller drives the positioning plate and the processing plate to move downward. At this time, the polishing unit is stationary, and the processing plate is moved to achieve the operation of polishing different positions. Moreover, the polishing disc does not move, and the debris does not fly around, which is convenient for collecting the polishing debris. The problems of difficult collection of polishing debris and complicated plate fixing operation in the existing polishing equipment are solved.

[0002] The blades of a wind turbine are an important part of the wind turbine. Their main function is to convert wind energy into mechanical energy and then convert the mechanical energy into electrical energy through a generator. The performance of the blades directly affects the power generation efficiency and capacity of the entire wind turbine. Therefore, for a wind turbine, the design and manufacture of the blades are crucial.

[0003] During the production process of wind power generation blades, a polishing operation is required. First, the plate for processing the wind power generation blades is installed on a multi-station fixture, and the polishing device is continuously moved to polish the surface of the plate. After polishing, it needs to be unlocked. However, it is found in actual use that during the processing, the polishing position needs to be continuously moved to polish different positions. As the polishing position moves, the polishing debris scatters outwards in each part, affecting the subsequent collection. The collection is relatively complicated, and after each processing is completed, the plate needs to be manually removed from the fixture, and the operation is relatively complicated, which is not conducive to improving the processing efficiency.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0041] Embodiment 1:

[0042] As Figures 1 to 9 shown, a polishing device for wind power generation blade production includes a support unit 100, a polishing unit 200, a displacement unit 300, and an unlocking unit 400. The support unit 100 includes a support seat 101. A positioning table 1033 is installed on the support seat 101. A guide ring 103 is rotatably installed on the positioning table 1033. A vertical rod 1031 is installed on the guide ring 103. The support seat 101 and the positioning table 1033 support the guide ring 103.

[0043] The shifting unit 300 includes a shifting motor 301 and four commutation rollers 302 installed on the inner wall of the guiding ring 103. A first half gear 3011 is installed at the output end of the shifting motor 301. A positioning tooth ring 3012 is meshed on the side wall of the first half gear 3011. The positioning tooth ring 3012 is connected to the vertical rod 1031. A second half gear 3014 is coaxially installed on the first half gear 3011. A positioning gear 3015 is meshed on the second half gear 3014. The rotation center of the positioning gear 3015 is connected to the commutation roller 302. An adjustment groove 303 is formed on the commutation roller 302. A positioning plate 304 is slidably arranged on the adjustment groove 303. The positioning plate 304 is inserted into the guiding ring 103. A processing plate 500 is installed on the surface of the positioning plate 304. A positioning column 3017 is installed on the positioning table 1033. A reset rack 3016 is installed on the positioning column 3017. The reset rack 3016 is adapted to the positioning gear 3015. The number of teeth of the second half gear 3014 is half of the number of teeth of the positioning gear 3015. And the number of teeth of the positioning gear 3015 is the same as that of the reset rack 3016. The polishing unit 200 includes a polishing motor 201. A polishing disc 2011 is installed at the output end of the polishing motor 201. The polishing disc 2011 corresponds to the processing plate 500. Among them, the four commutation rollers on the shifting unit correspond to four processing stations. When the shifting motor drives the first half gear to rotate, during the meshing process of the first half gear and the positioning tooth ring, the four commutation rollers complete the position switching and change the processing position. And when the first half gear is not meshed with the positioning tooth ring, at this time, the second half gear drives the positioning gear to rotate, and then drives the positioning gear located at the polishing position to rotate. The positioning gear drives the adjustment roller to rotate. The adjustment roller can drive the positioning plate and the processing plate to move downward. And at this time, the position of the polishing unit is in a static state. Moving the processing plate achieves the operation of polishing different positions. And the polishing disc does not move, resulting in that the debris will not fly randomly, thus facilitating the collection of the polishing debris. And during the rotation process of the adjustment roller, the positioning gear on one of the adjustment rollers can be re-meshed with the reset rack, reset the positioning plate again, and clamp a new processing plate, facilitating the polishing of the new workpiece.

[0044] The unlocking unit 400 includes a clamping cover 401, which is mounted on the bottom of the positioning plate 304. A baffle 403 is movably inserted at the bottom of the clamping cover 401. A plug rod 4031 is installed on the baffle 403. A slide plate 4032 is installed on the plug rod 4031. A push block 4033 is installed on the slide plate 4032. The push block 4033 is inserted into the clamping cover 401. A swing arm 402 is rotatably installed inside the clamping cover 401. A friction plate 4021 is installed at one end of the swing arm 402, and the friction plate 4021 and the processing plate 5 are connected. 00 side wall is fitted, a top block 4022 is installed at the other end of the swing arm 402, the top block 4022 and the push block 4033 are adapted, a rocker arm 404 is installed at the rotation center of the swing arm 402, a synchronous plate 4042 is installed on the rocker arm 404, an unlocking rod 4053 is installed on the synchronous plate 4042, two unlocking protrusions 4054 are installed on the support seat 101, the height of the unlocking protrusion 4054 corresponding to the polishing disk 2011 is lower than the height of the other unlocking protrusion 4054, and the unlocking rod 4053 and the unlocking protrusion 4054 correspond to each other. When the positioning plate moves to the unlocking protrusion, the unlocking rod is lifted and moved upward, driving the synchronous plate to slide, driving the rocker arm on the synchronous plate to rotate, and the rocker arm rotates outward to drive the swing arm to rotate synchronously. The friction plate of the swing arm is separated from the processed plate, and the unlocking operation is completed. As the movement continues, the top block on the swing arm pushes the push block to move, and the push block drives the baffle to move through the plug rod, so that the bottom of the clamping cover is opened, and the unloading operation can be completed by its own weight. When the positioning plate moves to the next shorter unlocking protrusion, the baffle is closed again, but the friction plate is open, which is convenient for putting in new workpieces and completing the clamping operation later, and the operation is simpler.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, in a specific embodiment, a support leg 1011 is installed at the bottom of the support seat 101, and an anti-skid pad is arranged at the bottom of the support leg 1011. The support leg 1011 and the anti-skid pad improve the stability of the device. A feed opening 1012 is installed on the surface of the support seat 101. The feed opening 1012 corresponds to the unlocking protrusion 4054 with a high height, and both sides of the unlocking protrusion 4054 are chamfered. The size of the feed opening 1012 corresponds to the processed plate 500. The feed opening is convenient for discharging the processed plate 500 later.

[0046] like Figure 1 , Figure 2 and Figure 3As shown in the figure, further, a support arm 102 is installed on the support base 101, a cross bar 1021 is installed on the support arm 102, a top plate 1022 is installed at the central position of the cross bar 1021, the top plate 1022 is rotatably connected to the vertical rod 1031, a guide plate 1032 is installed on the surface of the guide ring 103, the guide plate 1032 is in a seven-shaped form, and a positioning plate 304 and a processing plate member 500 are movably inserted into the guide plate 1032. The guide plate 1032 serves to limit the movement of the positioning plate 304 and the processing plate member 500.

[0047] Embodiment 2:

[0048] Differing from the above embodiment and this embodiment is that: As Figure 3 shown in the figure, a cross plate 202 is installed on the support arm 102, a bolt 2021 is screwed between the side wall of the cross plate 202 and the side wall of the support arm 102, the surface of the cross plate 202 and the outer shell of the polishing motor 201 are slidably connected through an electric slide rail, and the polishing motor 201 is in a horizontal state. The electric slide rail controls one end of the polishing motor 201 so that the polishing disc can contact the processing plate member 500.

[0049] As Figure 4 、 Figure 5 and Figure 6 shown in the figure, in the specific implementation manner, a synchronous shaft 3013 is installed between the first half gear 3011 and the second half gear 3014, the tooth positions of the first half gear 3011 and the second half gear 3014 are opposite, ensuring that only one gear can be meshed by the first half gear 3011 and the second half gear 3014 at the same time. A rotating shaft 3021 is installed at the rotation center of the positioning gear 3015, the rotating shaft 3021 is connected to the transposition roller 302, and a fixed seat 3022 is installed on the side wall of the rotating shaft 3021, and the fixed seat 3022 is installed on the side wall of the guide ring 103.

[0050] As Figure 4 、 Figure 5 and Figure 6 shown in the figure, further, a number of pairs of guide rollers 3041 are rotatably installed on the surface of the positioning plate 304, a connecting rod 3032 is installed on the positioning plate 304, a slider 3031 is installed on the connecting rod 3032, the slider 3031 is slidably arranged in the adjustment groove 303, and a limiting rod 3033 is movably penetrated through the slider 3031, and the limiting rod 3033 is installed on the guide ring 103. During the rotation of the transposition roller 302, the position of the adjustment groove 303 on the surface changes synchronously, so that the slider 3031 limited by the limiting rod 3033 moves downward, and the slider 3031 drives the positioning plate 304 on its surface to move downward through the connecting rod 3032, and the positioning plate 304 can drive the processing plate member 500 connected to its surface to move downward.

[0051] Embodiment 3:

[0052] Different from the above embodiments, this embodiment is as follows: As Figure 7 , Figure 8 and Figure 9 shown, a hollow inner cavity 4011 is formed inside the clamping cover 401, and a through hole is formed at the bottom of the hollow inner cavity 4011. The baffle 403 is placed in the through hole, and the processing plate 500 is inserted into the hollow inner cavity 4011. A pair of guide rods 4034 are installed on the side wall of the clamping cover 401, a pressing plate 4036 is installed at the end of the guide rods 4034, a sliding plate 4032 is inserted on the pair of guide rods 4034, a return spring 4035 is sleeved on the pair of guide rods 4034, one end of the return spring 4035 is clamped on the pressing plate 4036, and the other end of the return spring 4035 is clamped on the sliding plate 4032. During the rotation of the swing arm 402, the top block 4022 at the end of the swing arm 402 contacts the push block 4033, and the push block 4033 and the sliding plate 4032 move outward along the guide rod 4034. At this time, the distance between the push block 4033 and the pressing plate 4036 becomes smaller, so that the return spring 4035 can be compressed. After the return spring 4035 moves, the return spring 4035 is convenient for later reset. The movement of the sliding plate 4032 can drive the movement of the insertion rod 4031, and the insertion rod 4031 can pull the baffle 403 on the surface to move, so that the through hole at the bottom is opened. Then, the unlocked processing plate 500 can be discharged, and finally it can be discharged from the discharge port 1012.

[0053] As Figure 7 , Figure 8 and Figure 9As shown, in the specific implementation, a clamping shaft 4023 is installed at the rotation center of the swing arm 402. The clamping shaft 4023 movably penetrates through the outer shell of the clamping cover 401. The end of the clamping shaft 4023 is connected to the rotation center of the rocker arm 404. A strip-shaped groove 4041 is formed in the rocker arm 404. A sliding rod 4043 is installed on the synchronizing plate 4042, and the sliding rod 4043 is slidably arranged in the strip-shaped groove 4041. A protective cover 406 is installed on the clamping cover 401. The protective cover 406 covers the synchronizing plate 4042 and the rocker arm 404. A positioning rod 4051 is installed through the protective cover 406. A sliding seat 405 is slidably arranged on the positioning rod 4051. A compression spring 4052 is clamped between the sliding seat 405 and the protective cover 406, and the compression spring 4052 is sleeved on the positioning rod 4051. The unlocking rod 4053 movably penetrates through the protective cover 406. The unlocking rod 4053 will slide onto the unlocking protrusion 4054. Through the unlocking protrusion 4054, the unlocking rod 4053 and the synchronizing plate 4042 can be lifted upward. The sliding seat 405 on the synchronizing plate 4042 slides on the positioning rod 4051 and compresses the compression spring 4052. The compressed compression spring 4052 is convenient for later reset operation. When the synchronizing plate 4042 moves upward, the sliding rod 4043 on the synchronizing plate 4042 slides on the strip-shaped groove 4041 of the rocker arm 404, and finally the clamping shaft 4023 installed with the rocker arm 404 can be rotated.

[0054] The implementation principle of a polishing device for wind power generation blade production in this embodiment is as follows:

[0055] This figure is a schematic diagram of the overall internal structure of the polishing device. The outer shell of the device is not drawn in the figure.

[0056] First, this device has four processing stations, namely a polishing station, a discharging station, a feeding station, and a lifting station. As shown in the attached figure, the positioning plate 304 close to the polishing unit 200 is the polishing station, and the remaining stations are distributed counterclockwise in sequence. Figure 6 As shown, the positioning plate 304 close to the polishing unit 200 is the polishing station, and the remaining stations are distributed counterclockwise in sequence.

[0057] Take Figure 6Taking [benchmark], the shifting motor 301 is started at this time. The shifting motor 301 can drive the first half gear 3011 to rotate. At this time, the first half gear 3011 and the positioning gear ring 3012 are not in a meshed state. Thus, the positioning gear ring 3012, the vertical rod 1031, and the guide ring 103 are in a stationary state. Therefore, the processing station will not be changed at this time. However, during the rotation of the first half gear 3011, the synchronous shaft 3013 at the bottom of the first half gear 3011 drives the second half gear 3014 to rotate. At this time, the second half gear 3014 is exactly meshed with the positioning gear 3015. Thus, it can drive the positioning gear 3015 to rotate half a circle, driving the coaxial connected rotating shaft 3021 to rotate half a circle. The rotating shaft 3021 can drive the commutation roller 302 to rotate synchronously by half a circle.

[0058] During the rotation of the commutation roller 302, the position of the adjustment groove 303 on the surface changes synchronously. Thus, the slider 3031 limited by the limiting rod 3033 moves downward. The slider 3031 drives the positioning plate 304 on the surface to move downward through the connecting rod 3032. The positioning plate 304 can drive the processing plate member 500 connected to the surface to move downward. At this time, the polishing motor 201 in the polishing unit 200 drives the polishing disc 2011 to rotate. The polishing disc 2011 can contact the moving processing plate member 500. Thus, the processing plate member 500 can be polished. After the polishing is completed, the polishing disc 2011 and the processing plate member 500 are separated by the electric slide rail.

[0059] At this time, the second half gear 3014 and the positioning gear 3015 are separated, and the first half gear 3011 and the positioning gear ring 3012 are in a meshed state. Thus, the positioning gear ring 3012 starts to rotate at this time. The positioning gear ring 3012 drives the processed plate member 500 that has been polished to move to the discharging station.

[0060] During the movement, the unlocking rod 4053 will slide onto the unlocking protrusion 4054. The unlocking protrusion 4054 can lift the unlocking rod 4053 and the synchronous plate 4042 upward. The sliding seat 405 on the synchronous plate 4042 slides on the positioning rod 4051 and compresses the compression spring 4052. The compressed compression spring 4052 facilitates the later reset operation. When the synchronous plate 4042 moves upward, the sliding rod 4043 on the synchronous plate 4042 slides in the strip-shaped groove 4041 of the rocker arm 404. Finally, it can drive the clamping shaft 4023 installed with the rocker arm 404 to rotate. At this time, the clamping shaft 4023 can drive the swing arm 402 on the surface to rotate. The friction plate 4021 on the swing arm 402 is first separated from the processing plate member 500, completing the unlocking operation of the processing plate member 500.

[0061] During the continuous rotation of the swing arm 402, the top block 4022 at the end of the swing arm 402 contacts the push block 4033, and the push block 4033 and the slide plate 4032 move outward along the guide rod 4034. At this time, the distance between the push block 4033 and the pressure plate 4036 becomes smaller, and thus the return spring 4035 can be compressed. After the return spring 4035 moves, the return spring 4035 at this time is convenient for later reset. The movement of the slide plate 4032 can drive the movement of the insertion rod 4031, and the insertion rod 4031 can pull the baffle plate 403 on the surface, so that the through hole at the bottom is opened. Then, the unlocked processed plate 500 can be discharged, and finally it can be discharged from the discharge port 1012.

[0062] When the discharging is completed, at this time, the first half gear 3011 and the positioning tooth ring 3012 move the raw material at the discharging station to the feeding station. At this time, the unlocking rod 4053 moves onto the unlocking protrusion 4054, but the height of the unlocking protrusion 4054 at this position is relatively low. Therefore, the swinging amplitude of the swing arm 402 is not that large. So at this time, the rotation of the swing arm 402 can only drive the unlocking of the friction plate 4021 and cannot open the baffle plate 403. Then, the operator can convey the processed plate 500 into it;

[0063] After the feeding is completed, at this time, the first half gear 3011 and the positioning tooth ring 3012 convey the raw material at the feeding station to the lifting station. During the movement, the positioning gear 3015 at this position meshes with the return rack 3016, and thus the positioning gear 3015 can be driven to rotate, and the positioning plate 304 and the processed plate 500 are lifted upward again.

[0064] And finally, it is conveyed to the polishing station through the first half gear 3011 and the positioning tooth ring 3012 to complete a cycle of circulation.

[0065] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
