Description

Technical Field

[0001] The invention relates to the technical field of mechanical equipment, and in particular to a large-size foam body grinding device and process. Background Art

[0002] At present, large-size foam bodies are widely used. On ships and docks, the common large-size foam bodies are usually cylindrical with arc-shaped edges. The diameter is generally more than 1 meter, and some have a diameter of more than 2 meters. Some large-size foam bodies need to be sprayed with a protective layer on the outermost layer. In order to achieve the required spraying effect, the large-size foam body needs to be polished on the outer surface after it is formed, and then sprayed after polishing.

[0003] For the circumferential surface, if mechanical grinding is adopted, the usual method is to use a grinding wheel to make the grinding wheel and the large-sized foam body move relative to each other. However, because the foam body has a large diameter and is heavy (generally more than 200kg, and some are more than 500kg), if the diameter of the grinding wheel is small, because the surface of the foam body is uneven, it is very easy to jam the grinding wheel when the two circles move relative to each other, causing the power device of the grinding wheel to shut down or fail. In addition, if the diameter of the grinding wheel is small, a very strong power is required, and the power device cost is high. If the power device is jammed during the grinding process and fails, the maintenance or replacement cost is very high. In order to achieve an efficient and economical grinding effect, this requires that the diameter of the grinding wheel needs to exceed the diameter of the large-sized foam body to achieve efficient grinding efficiency, and the grinding wheel is equipped with a strong power, but the grinding equipment with a large-diameter grinding wheel is large in size, the equipment cost is also high, and the operation is inconvenient. Therefore, in the foam industry, the existing grinding methods all rely on manual grinding. The problems of manual grinding include: the circumference size and edge arc size are not accurately controlled, and the standard circle and required arc cannot be ground out; the grinding efficiency is low; the dust is large and the environment is poor, and the dust causes damage to the health of the grinding personnel. Therefore, studying how to improve the efficiency of foam grinding, simplify the structure of the foam grinding device, and reduce the cost of foam grinding is one of the problems that need to be solved urgently.

[0004] Patent CN107234521B discloses a preparation device for a solid polyurea elastomer floating on water, which first moves the workpiece left and right along a slide rail and fixes the workpiece at both ends, then adjusts the position of the tool, and then starts the second variable frequency motor to complete the cutting or grinding process until the product is processed into the desired shape; the grinding efficiency of the elastomer can be improved, but on the one hand, since the processing object in the patent is essentially a polyurea elastomer, it belongs to a local surface processing method after the foam polyurea is sprayed, and its preparation device uses a method of first fixing the entire workpiece and then cutting or grinding. The entire workpiece cannot rotate. Therefore, the cutting or grinding process of the polyurea elastomer by the device is partial processing, and the entire outer surface of the foam cannot be quickly ground. On the other hand, the position of the tool set by the device cannot quickly grind the edge of the foam to a circular arc size, and it cannot effectively avoid the influence of dust on the operator.

[0005] Patent CN219853740U discloses a fender arc surface grinding machine, which is provided with two grinding wheels. When grinding the fender arc surface, the grinding speed can be accelerated, which greatly improves the work efficiency. Since the cleaning device is provided on the device, grinding and cleaning can be performed at the same time, no additional equipment and manpower are required, which improves the work efficiency and product quality, and also reduces the dust generated during grinding. However, since the two grinding wheels of the grinder are arranged in parallel on the top of the grinder, the platform is a conveyor belt, which cannot drive the fender to rotate, and still cannot achieve rapid grinding of the arc at the edge of the fender and the circumferential surface of the fender. In addition, the grinder is provided with a water spray device for dust removal. If the water spray function is enabled during grinding, the residual moisture on the surface of the fender after grinding is easy to cause bulging or pinhole quality problems in the polyurea spraying process of the subsequent process.

[0042] The arrangement of columns 11 of different specifications is conducive to simplifying the structure of the frame 1, facilitating the disassembly and assembly of the foam body, and also conducive to improving the visualization of the foam body grinding process, improving the accuracy of the foam body grinding, enhancing the ability to handle abnormal foam body grinding in a timely manner, and reducing losses during the foam body grinding process.

[0043] The base 12 includes a first crossbar 121, a second crossbar 122, a third crossbar 123, a fourth crossbar 124 and a bottom frame 125.

[0045] The support device 2 includes an active support end 21, a driven support end 22 and a centering shaft 23. The active support end 21 and the driven support end 22 are both arranged at the top of the column 11, and the centering shaft 23 is arranged between the active support end 21 and the driven support end 22. Specifically, the active support end 21 is arranged at the top of the fourth column 114, and the active support end 21 is connected to the power device 5 through a synchronous belt, and the driven support end 22 is arranged at the top of the second column 112. Under the power supply of the power distribution system 6, the operation of the power device 5 drives the active support end 21, the centering shaft 23 and the driven support end 22 to move in sequence.

One end of the first support seat 211 is arranged at the bottom of the fourth column 114, and the other end of the first support seat 211 is connected to the centering shaft 23 and the first gear 212 respectively. A through hole is arranged at the end of the first support seat 211 away from the fourth column 114, which is used to provide support for the installation of the centering shaft 23.

[0046] Different from the patent CN107234521B, the processing procedure is to process the surface of the polyurea elastomer after the polyurea spraying of the foam is completed. During the processing, the polyurea elastomer cannot rotate, and the partial processing of the elastomer by fixing it is likely to cause the problem of low grinding efficiency. The processing procedure of the present application is to process the foam surface before the polyurea spraying of the foam. During the processing, through the arrangement of the components in the support device 2, it is possible to achieve the transmission effect on the foam by cooperating with the power device 5, which is convenient for driving the foam to rotate, so that the grinding device 3 can quickly grind the entire outer surface of the foam, thereby improving the grinding efficiency, and is also conducive to improving the convenience of disassembly and assembly of the foam, and enhancing the safety of the foam after installation.

[0047] The grinding device 3 includes a guide rail 31, a grinding power head 32, a grinding piece 33 and a first rocker 34; the guide rail 31 is arranged at the top of the third column 113 and the sixth column 116; the bottom of the grinding power head 32 is arranged on the guide rail 31 through a pulley in a manner that it can slide left and right, one end of the first rocker 34 is arranged at the rear side of the grinding power head 32, and the other end of the first rocker 34 penetrates the grinding power head 32 and is connected to the grinding piece 33. Through the action of the first rocker 34, the grinding piece 33 can be telescopically moved forward and backward, so as to facilitate the replacement of the grinding piece 33 and to facilitate the adjustment of the position of the grinding piece 33 according to the position of different foam bodies. Among them, according to different requirements for grinding the foam body, the grinding piece 33 is a conventional milling cutter and / or a grinding wheel for an angle grinder. At least one grinding power head 32 and grinding piece 33 are provided. The guide rail 31 can drive the grinding power head 32 to move from left to right when powered on.

[0048] Preferably, three grinding power heads 32 are provided, two of which are equipped with milling cutters, and one of which is equipped with a grinding wheel. By only controlling the distance between the two milling cutters and one grinding wheel and the central axis of the foam body, the surface of the foam body can be polished smooth in one go. The grinding efficiency is greatly improved compared with manual grinding, and the grinding effect is far better than manual grinding. In addition, a synchronous dust suction device is configured on the grinding equipment, so that the grinding dust can be cleaned up in time, greatly improving the grinding environment. The entire grinding process is automatically controlled to achieve automatic grinding, which solves the damage of dust to personnel health and also reduces labor costs.

[0049] Different from the parallel trajectories of two circular relative motions, the grinding method of two circular relative motions is not suitable for production. The present application provides a grinding device with a vertical motion trajectory, using a conventional power head, on which a conventional milling cutter or a grinding wheel for an angle grinder is installed, and a method similar to lathe processing is adopted to achieve efficient and economical grinding of the circular surface. A motor with a customized R-angle grinding wheel is used to achieve arc grinding of the edge of a large-sized foam body. By setting the grinding device 3, the grinding efficiency of the foam body can be effectively improved, and it is also beneficial to improve the grinding effect of the foam body and improve the accuracy of the grinding of the foam body surface.

[0050] At least one angle forming device 4 is provided. The angle forming device 4 includes an angle forming motor 401, a third support seat 402, a second rocker 403 and a third rocker 404; the angle forming motor 401 is provided at the top of the column 11 through the third support seat 402, the output end of the angle forming motor 401 is provided toward the foam body, the second rocker 403 and the third rocker 404 are both provided on the third support seat 402, the second rocker 403 is used to control the angle forming motor 401 to move in the direction from front to back, and the third rocker 404 is used to control the angle forming motor 401 to move in the direction from left to right, thereby realizing the precise grinding of the edge of the foam body by the angle forming motor 401. The angle forming motor 401 includes an arc grinding wheel, which is provided on the output shaft of the angle forming motor 401, and is used to facilitate efficient grinding of the edge of the foam body. The generatrix of the arc grinding wheel is an arc shape, and the radius of the generatrix of the arc shape is R, and the specific value of R is set according to the needs. When two angle forming devices 4 are provided, the angle forming devices 4 include an angle forming device 1 41 and an angle forming device 2 42. The angle forming device 1 41 is provided at the top of the first column 111, the output end of the angle forming motor 401 is provided toward the right, and the second rocker 403 and the third rocker 404 are provided at the front and left sides of the third support seat 402, respectively. The angle forming device 2 42 is provided at the top of the fourth column 114, the output end of the angle forming motor 401 is provided toward the left, and the second rocker 403 and the third rocker 404 are provided at the front and right sides of the third support seat 402, respectively.

[0051] The arrangement of the angled motor 401 with a fixed R angle grinding wheel in the angled device 4 facilitates grinding the edge of the foam body into a required arc size under the joint action of the second rocker 403 and the third rocker 404 .

[0052] The power device 5 includes a transmission motor 51 and a second gear 52. One end of the transmission motor 51 is arranged on the bottom frame 125 of the base 12, and the second gear 52 is arranged on the other end of the transmission motor 51. The second gear 52 corresponds to the position of the first gear 212. The second gear 52 is connected to the first gear 212 through a synchronous belt. When power is turned on, the transmission motor 51 drives the second gear 52 and the first gear 212 to move, so that the support device 2 drives the foam body to rotate.

[0053] The arrangement of the power device 5 is helpful to improve the stability of the foam body rotation, enhance the safety of the foam body rotation, and also help to reduce the cost of the grinding equipment.

[0054] Working principle:

[0055] The large-sized foam body is installed on the transmission device, i.e., the centering shaft 23, for rotation. The grinding power head 32 with a milling cutter approaches the foam body surface along the circumferential direction of the foam body. The distance between the grinding power head 32 and the outer surface of the foam body is controlled by the first rocker 34, so that the foam body surface in contact can be milled into a circle. Then, the grinding power head 32 with a milling cutter is moved along the length direction of the foam body, so that the entire foam body surface can be milled into a circle. After the foam body surface is completely milled into a circle, the foam body surface is not smooth. In order to grind the foam body surface smoothly, the milling cutter is replaced with a grinding wheel. The power head with a grinding wheel approaches the foam body surface along the circumferential direction. By controlling the distance, the foam body surface in contact can be polished into a smooth state. Then, the power head with a grinding wheel is moved along the length direction of the foam body, so that the entire foam body surface can be polished into a smooth state. In order to improve the grinding efficiency, multiple power heads can be allowed to work at the same time, some power heads are equipped with milling cutters, and some power heads are equipped with grinding wheels. In addition, the angled motor 401 with a customized R-angle grinding wheel first adjusts the distance between the grinding wheel and the central axis of the foam body to a suitable position, and controls the customized R-angle grinding wheel to approach the surface of the foam body. By controlling the distance, the surface of the foam body in contact can be ground into an arc shape, and then the customized R-angle grinding wheel is controlled to move to a suitable position along the length direction of the foam body, so that the edge of the foam body can be ground into the required arc size.

[0056] A large-size foam body grinding process, the process is applied to a large-size foam body grinding device, the process comprises the following steps:

[0057] Step 1: Install the foam body: install the large-sized foam body on the supporting device 2, and install the required milling cutter and / or grinding wheel on the grinding power head 32;

[0058] Step 2: Turn on the power, start the power device 5 to drive the foam body to rotate, and then start the dust collection device to perform dust collection on the grinding space in the protective cover;

[0059] Step 3, grinding the foam body surface: start the grinding power head 32 in sequence, shake the first rocker 34, adjust the grinding power head 32 to the desired position, and use the milling cutter and / or grinding wheel to first mill and then grind the outer surface of the foam body in contact with it, and then start the guide rail 31 to enable the grinding power head 32 to move along the length direction of the foam body to grind the entire surface of the foam body smoothly; and shake the first rocker 34 to adjust the grinding power head 32 to move away from the foam body; complete the grinding of the foam body surface;

[0060] Step 4: Grinding the edge of the foam body: Start the angle motor 401, and under the action of the second rocker 403 and the third rocker 404, adjust the customized R angle sand, i.e., the arc-shaped grinding wheel, to the edge position of the foam body to be grinded; grind the edges of the left and right ends of the foam body to the required arc size; and complete the grinding of the edge of the foam body;

[0061] Step 5: Stop the machine and remove the polished foam body from the supporting device 2 to obtain the polished foam body.

[0062] In the current foam industry, the surface polishing of large-sized foam bodies is all done manually, which not only has poor polishing effect, low polishing efficiency, and high labor costs, but also has a poor polishing environment and dust that is harmful to the health of the polishers. The present application adopts a turning and milling processing method similar to a lathe. First, the large-sized foam body is installed on the support device 2, which is rotated under the action of the power device 5. The milling cutter and the grinding wheel are respectively installed on the polishing power head 32, and the polishing power head 32 is controlled to approach different positions on the surface of the foam body. The surface of the foam body is first turned and milled, and then polished smooth. The polishing equipment is equipped with a synchronous dust suction device, which can clean up the dust in time and improve the polishing environment; an automatic control device is configured to realize automatic polishing, improve the polishing effect and polishing efficiency, reduce labor costs, and solve the damage to the health of the polishers caused by dust during manual polishing. In addition, through the process, the setting of the process steps can be simplified, the convenience of operation can be improved, the foam processing time can be shortened, and efficient and economical polishing can be achieved.

[0063] In addition, the motion trajectory of the grinding device 3 is perpendicular to the rotation motion trajectory of the foam body. The grinding equipment uses a turning and milling method to grind the foam body; a milling cutter and a grinding wheel are used during turning and milling; the distance between the milling cutter and the grinding wheel and the central axis of the foam body is adjustable; the milling cutter and the grinding wheel can move along the length direction of the foam body; the distance between the R-angle grinding wheel, that is, the arc-shaped grinding wheel and the central axis of the foam body can be adjusted; the distance between the R-angle grinding wheel and the central axis of the foam body is adjustable. The entire grinding process can be automatically controlled. The grinding dust can be collected and cleaned in time.

[0064] Different from the prior art which usually adopts the method of grinding to process the surface of the foam body, which is prone to getting stuck, the present application adopts the grinding device 3 whose motion trajectory is perpendicular to the rotational motion trajectory of the foam body, which can effectively improve the stability and safety of the foam body grinding, and can also reduce the damage caused to the foam body by the grinding equipment during the grinding process, which is beneficial to extend the service life of the grinding equipment, and is also beneficial to improve the grinding efficiency and ensure the grinding effect.

Since they are all prior arts, they will not be elaborated here.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
