Abstract
Description
Technical Field
[0001] This utility model belongs to the field of surface treatment of precast concrete components, and in particular relates to a surface grinding device for precast concrete components. Background Technology
[0002] Precast concrete components are widely used in the construction industry due to their advantages such as high production efficiency, stable quality, and standardized production. During the production process, some precast components require surface grinding to achieve the required flatness, smoothness, or to remove burrs and flash. This is crucial for subsequent construction quality, component appearance, and the adhesion of potential anti-corrosion and decorative coatings.
[0003] Common methods for grinding the surface of precast concrete components mainly include manual grinding and simple mechanical grinding. Manual grinding uses handheld grinding tools, which is labor-intensive and inefficient. The grinding quality depends on the worker's skill level and condition, making it difficult to guarantee consistency. In addition, the large amount of dust generated during the operation poses a serious threat to the worker's health. Even with protective equipment, the working environment is still harsh. Although some simple mechanical grinding devices reduce the labor intensity to a certain extent, they generally have problems with low automation and limited functions. The adjustment of the grinding position usually relies on manual operation, which is not precise or efficient, making it difficult to achieve accurate and efficient automated grinding operations.
[0004] Therefore, a highly efficient and precisely positioned surface grinding device for precast concrete components is needed to solve the problem of inaccurate positioning during manual grinding or simple mechanical grinding. Utility Model Content

[0037] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0038] like Figure 1 As shown, a surface grinding device for precast concrete components includes a frame 1, a rotating assembly 2, a grinding assembly 3, and a dust removal assembly 4. The periphery of the precast component 5 is rotatably connected to the rotating assembly 2. The rotating assembly 2 is rotatably installed inside the frame 1. The grinding assembly 3 is provided on one side of the frame 1. The dust removal assembly 4 is fixedly installed at the lower end of the grinding assembly 3. The dust suction end of the dust removal assembly 4 faces the precast component 5, and the other end of the dust removal assembly 4 is connected to an external vacuum cleaner. The rotating assembly 2 is used to rotate the precast component 5, the grinding assembly 3 is used to grind the outer surface of the precast component 5, and the dust removal assembly 4 is used to suck up the dust scattered during the grinding process.
[0039] like Figure 2As shown, the rotating assembly 2 includes two rollers 21 and a drive unit 22. The two rollers 21 are arranged parallel to each other, and both ends of each roller 21 are rotatably connected to the frame 1. The periphery of each roller 21 is rolledly connected to the periphery of the preform 5. The periphery of the roller 21 is provided with anti-slip textures 211, which are arranged in a spiral pattern. The anti-slip textures 211 on the periphery of the roller 21 further enhance the friction between the roller and the preform 5, effectively avoiding the problem of asynchronous rotation caused by relative sliding between the two, ensuring that the preform 5 can rotate stably with the roller 21, which facilitates uniform grinding of the outer surface of the preform 5. By setting up the rotating assembly 2, the outer surface of the preform can be uniformly ground, solving the problem of frequent manual flipping of the preform in traditional manual or simple mechanical grinding, and greatly improving the grinding coverage and work efficiency.
[0040] like Figure 3 As shown, the drive unit 22 includes a first servo motor 221, a sprocket 222, and a chain 223. The first servo motor 221 is fixedly installed on one side of the frame 1. The output gear of the first servo motor 221 and the chain 223 are sleeved around the sprocket 222 to form a synchronous transmission structure. The sprocket 222 is fixedly connected to one end of any roller shaft 21. The first servo motor 221 is existing technology, and the model of the first servo motor 221 is SIMOTICS S-1FL6. When the first servo motor 221 in the drive unit 22 is started, the output gear drives the sprocket 222 fixed to one end of the roller shaft 21 to rotate synchronously through the chain 223, thereby driving the roller shaft 21 to rotate. Since the two roller shafts 21 are parallel to each other and are rotatably connected in the frame 1, when one roller shaft 21 is driven to rotate, the preform 5 placed above the two roller shafts 21 rotates with the roller shaft 21 under the action of friction, and at the same time drives the other roller shaft 21 that is not directly driven to rotate passively.
[0041] like Figure 4 As shown, the grinding assembly 3 includes a longitudinal displacement unit 31, a transverse displacement unit 32, and a grinding head 33. The longitudinal displacement unit 31 is located on one side of the frame 1. One end of the transverse displacement unit 32 is slidably connected to the upper end of the longitudinal displacement unit 31, and the grinding head 33 is installed at the other end of the transverse displacement unit 32. Figure 5As shown, the longitudinal displacement unit 31 includes a first mounting base 311, two first slide rails 312, a first slider 313, a lead screw 314, and a second servo motor 315. The first mounting base 311 is provided on one side of the frame 1. Two first slide rails 312 are fixedly installed in the first mounting base 311. The two first slide rails 312 are parallel to each other and facing each other. The outer periphery of each first slide rail 312 is slidably connected to one side of the first slider 313. The upper end of the first slider 313 is fixedly installed with a transverse displacement unit 32. The lead screw 314 is also rotatably connected in the first mounting base 311. The lead screw 314 and the first slide rails 312 are parallel to each other. The outer periphery of the lead screw 314 is threadedly connected to the first slider 313. The second servo motor 315 is provided on one side of the outside of the first mounting base 311. The output shaft of the second servo motor 315 is fixedly connected to one end of the lead screw 314.
[0042] The second servo motor 315 is existing technology. The model of the second servo motor 315 is SIMOTICS S-1FL6. The controller drives the output shaft of the second servo motor 315 to rotate. The output shaft drives the lead screw 314, which is fixedly connected to it, to rotate in the first mounting base 311. Since the outer periphery of the lead screw 314 is threadedly connected to the first slider 313, the rotational motion of the lead screw is converted into the linear motion of the first slider 313 through the threaded transmission, so that the first slider 313 slides along the outer periphery of the two first slide rails 312. Therefore, the longitudinal sliding of the first slider 313 will synchronously drive the transverse displacement unit 32 and the grinding head 33 to move longitudinally, thereby realizing the position adjustment of the grinding head 33 in the longitudinal direction.
[0043] like Figure 6 As shown, the lateral displacement unit 32 includes a second mounting base 321, two second slide rails 322, a second slider 323, and two cylinders 324. The second mounting base 321 is fixed to the upper end of the first slider 313. Two second slide rails 322 are arranged inside the second mounting base 321. The two second slide rails 322 are parallel to each other and facing each other. The outer periphery of each second slide rail 322 is slidably connected to one side of the second slider 323. One end of the second slider 323 is fixedly connected to a grinding head 33. The fixed ends of two cylinders 324 are also fixedly connected inside the second mounting base 321. The two cylinders 324 are arranged parallel to each other. The movable ends of 324 are all fixedly connected to the second slider 323. The cylinder 324 is existing technology, and the model of the cylinder 324 is TN16-30-30. The two cylinders 324 installed in the second mounting base 321 start synchronously, and their movable ends extend outward or retract inward, driving the second slider 323 fixedly connected to it to slide along two parallel second slide rails 322. Since one end of the second slider 323 is directly connected to the grinding head 33, the lateral sliding of the slider will synchronously drive the grinding head 33 to approach or move away from the outer surface of the preform 5, thereby realizing the position adjustment of the grinding head 33 in the lateral direction.
[0044] like Figure 7 As shown, the grinding head 33 includes a support plate 331, a synchronous pulley 332, a grinding wheel 333, a synchronous belt 334, a rotary motor 335, a bracket 336, and a dust cover 337. One end of the second slider 323 is fixedly connected to the support plate 331. The rotary motor 335 and the bracket 336 are fixedly installed on the upper end of the support plate 331. The grinding wheel 333 is rotatably connected inside the bracket 336. The outer periphery of the grinding wheel 333 is rollingly connected to the outer periphery of the precast part 5. One end of the grinding wheel 333 is fixedly connected to the synchronous pulley 332. The outer periphery of the synchronous pulley 332 and the outer periphery of the output wheel of the rotary motor 335 are connected by the synchronous belt 334 to form a synchronous transmission structure. The outer periphery of the synchronous belt 334, the synchronous pulley 332, and the output wheel of the rotary motor 335 is provided with a dust cover 337. The dust cover 337 is detachably installed on one side of the bracket 336. The rotary motor 335 is existing technology, and the model of the rotary motor 335 is MINAS A6.
[0045] The rotating motor 335, fixed on the upper end of the support plate 331, starts. Its output wheel drives the synchronous wheel 332 at one end of the grinding wheel 333 to rotate through the synchronous belt 334 sleeved on the outside. This drives the grinding wheel 333, which is rotatably connected in the bracket 336, to rotate at high speed. During the grinding process, the speed of the grinding wheel 333 is different from that of the roller shaft 21, and the speed of the grinding wheel 333 is much higher than that of the roller shaft 21. When the grinding wheel 333 reaches the working speed, under the drive of the transverse displacement unit 32 and the longitudinal displacement unit 31, the outer periphery of the grinding wheel 333 gradually approaches and contacts the outer surface of the preform 5. Through the friction between the high-speed rotating grinding wheel 333 and the surface of the preform 5, the outer surface of the preform is ground. A detachable dust cover 337 is also provided to protect the dust generated during the grinding process from entering the drive structure. The detachable design also facilitates maintenance and replacement of parts, extending the service life of the grinding assembly 3.
[0046] like Figure 8 As shown, the dust removal assembly 4 includes a dust collection box 41, a pipe 42, and multiple clips 43. The dust collection box 41 is fixedly installed at the lower end of the bracket 336. The open end of the dust collection box 41 faces the periphery of the prefabricated part 5. One side of the dust collection box 41 is connected to one end of the pipe 42, and the other end of the pipe 42 is connected to an external vacuum cleaner. The pipe 42 is installed on one side of the bracket 336 and the second slider 323 through the clips 43. The vacuum cleaner is existing technology, and the model of the vacuum cleaner is Degaojie VA022z.
[0047] like Figure 9As shown, a first distance sensor 6 is provided at the upper end of the first mounting base 311. The sensing end of the first distance sensor 6 faces one side of the second mounting base 321. The first distance sensor 6 is used to determine the longitudinal position of the grinding head 33. A second distance sensor 7 is provided inside the second mounting base 321. The sensing end of the second distance sensor 7 faces the second slider 323. The second distance sensor 7 is used to determine the lateral position of the grinding head 33. The first distance sensor 6 is prior art, and its model is SickOD2000. The second distance sensor 7 is prior art, and its model is SickOD2000.
[0048] The lateral position of the grinding wheel 333 relative to the periphery of a concrete precast component of a certain size is set in the controller according to the required grinding thickness. The longitudinal position of the grinding head 33 is determined by measuring the distance between the second mounting base 321 and the first distance sensor 6. The lateral position of the grinding head 33 is determined by measuring the distance between the second slider 323 and the first distance sensor 7. The data from the two sensors are combined to accurately locate the position of the grinding wheel 333 in two-dimensional space.
[0049] The working process of a surface grinding device for precast concrete components:
[0050] The precast component 5 is hoisted onto the rotating assembly 2 inside the frame 1, so that its outer periphery is rolledly connected to two parallel roller shafts 21. Then, the first servo motor 221 is started, driving one of the roller shafts 21 to rotate through the transmission of the sprocket 222 and the chain 223. Under the friction of the anti-slip texture 211 on the outer periphery of the roller shaft 21, the precast component 5 rotates synchronously with the roller shaft 21, and drives the other roller shaft 21 to rotate passively, realizing the stable rotation of the precast component 5. The controller controls the grinding assembly 3 to start working. The second servo motor 315 in the longitudinal displacement unit 31 drives the lead screw 314 to rotate, so that the first slider 313 slides longitudinally along the first slide rail 312, driving the transverse displacement unit 32 and the grinding head 33 to adjust the longitudinal position. The two cylinders 324 of the transverse displacement unit 32 extend and retract synchronously, pushing the second slider 323 along the first slide rail 312. The two slide rails 322 slide laterally, bringing the grinding head 33 closer to the precast component 5. The rotating motor 335 of the grinding head 33 drives the grinding wheel 333 to rotate at high speed through the synchronous belt 334 and the synchronous pulley 332 to grind the outer surface of the precast component 5. During the grinding process, the speed of the grinding wheel 333 is different from that of the roller 21, and the speed of the grinding wheel 333 is much higher than that of the roller 21. The lateral position of the grinding wheel 333 from the periphery of a concrete precast component of a certain size is set in the controller according to the required grinding thickness. The longitudinal and lateral positions of the grinding head 33 are monitored by the first distance sensor 6 and the second distance sensor 7, respectively. The dust collection box 41 of the dust removal component 4, under the action of the external vacuum cleaner, sucks away the dust generated by grinding through the pipe 42, and finally achieves uniform grinding of the outer surface of the precast component 5.
[0051] The control method in this embodiment is controlled by a controller. The controller circuit can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this document is mainly used to protect mechanical devices, and the control method and circuit connection will not be explained in detail here.
[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
