Detailed Implementation

[0030] The following will describe specific embodiments and appendices. Figure 1-9 The technical solutions in the embodiments of the present invention will be clearly and completely described.

[0031] Combination Figure 1-2 As shown, this embodiment of the present disclosure provides an apparatus for grinding steel templates, comprising: a support frame 100, a first roller brush 200, and a second roller brush 300. A telescopic assembly 400 is provided inside the support frame 100; one end of the first roller brush 200 is rotatably connected to the telescopic assembly 400; one end of the second roller brush 300 is rotatably connected to the telescopic assembly 400, and the other end is connected to the other end of the first roller brush 200 via a universal joint 500; wherein, the telescopic assembly 400 can drive the end of one of the first roller brush 200 and the second roller brush 300 to move, and under the action of the universal joint 500, rotate relative to the other of the first roller brush 200 and the second roller brush 300, so that the axis of the first roller brush 200 and the axis of the second roller brush 300 form an angle adapted to the angle of the grinding surface of the steel template.

[0032] The apparatus for grinding steel templates provided in this embodiment can drive the end of one of the first roller brush 200 and the second roller brush 300 to move when the grinding surface of the steel template is irregularly shaped. Under the action of the universal joint 500, the end of one of the first roller brush 200 and the second roller brush 300 rotates relative to the other, so that the axis of the first roller brush 200 and the axis of the second roller brush 300 form an angle that matches the angle of the grinding surface of the steel template. The first roller brush 200 and the second roller brush 300 then adhere to and grind the grinding surface of the steel template, improving the grinding effect, increasing the grinding efficiency, and reducing the cost of grinding steel templates.

[0033] For example, the telescopic component 400 is located above the first roller brush 200 and the second roller brush 300. The first roller brush 200 and the second roller brush 300 are initially in a horizontal position. The lower end of the telescopic component 400 is rotatably connected to the ends of the first roller brush 200 and the second roller brush 300, respectively. Taking the telescopic component 400 driving the end of the first roller brush 200 to rise as an example, the end of the first roller brush 200 gradually changes from a horizontal state to an inclined state as the telescopic component 400 rises, forming an angle between the first roller brush 200 and the second roller brush 300. The telescopic component 400 can also drive the first roller brush 200 and the second roller brush 300 to move up and down simultaneously to adapt to grinding surfaces with different inclination angles. The telescopic component 400 can also drive the first roller brush 200 and the second roller brush 300 to move simultaneously, adjusting the height of the first roller brush 200 and the second roller brush 300 relative to the grinding surface of the steel template.

[0034] Combination Figure 3 As shown, optionally, a sliding rod 501 is provided on the side wall of the universal joint 500 facing the first roller brush 200, and the universal joint 500 is slidably connected to the first roller brush 200 through the sliding rod 501. In this way, the sliding rod 501 can be slidably adjusted relative to the first roller brush 200 to adjust the distance between the second roller brush 300 and the first roller brush 200. When one of the first roller brush 200 and the second roller brush 300 rotates relative to each other, so that the axis of the first roller brush 200 and the axis of the second roller brush 300 form an angle adapted to the angle of the grinding surface of the steel template, the distance between the first roller brush 200 and the second roller brush 300 is increased to avoid mutual interference between them. When the axes of the first roller brush 200 and the second roller brush 300 gradually decrease in size and their axes coincide, the distance between the first roller brush 200 and the second roller brush 300 is shortened, making the grinding surface of the steel template more concentrated for the first roller brush 200 and the second roller brush 300.

[0035] Combination Figure 4 and Figure 5As shown, optionally, the lower end of the telescopic assembly 400 is provided with a first rotating frame 410. One end of the first roller brush 200 is rotatably connected to the first rotating frame 410 via a first rotating shaft 210, and the other end of the first roller brush 200 can perform circular motion around the first rotating shaft 210. This improves the stability of the rotatable connection between the end of the first roller brush 200 and the first rotating frame 410. When the telescopic assembly 400 drives the end of the first roller brush 200 to rise and fall, the first roller brush 200 can stably perform circular motion around the first rotating shaft 210, forming an angle with the second roller brush 300.

[0036] Specifically, the end of the first roller brush 200 facing away from the second roller brush 300 is rotatably connected to the first rotating frame 410 via the first rotating shaft 210. Optionally, one end of the first roller brush 200 is fixedly connected to the first rotating shaft 210, and a first driving member 220 is provided on one side of the first rotating frame 410, with the output end of the first driving member 220 connected to the first rotating shaft 210. Thus, since the first roller brush 200 and the second roller brush 300 are movably connected via a universal joint 500, gravity can cause the connecting end of the first roller brush 200 and the second roller brush 300 to tend to move downwards, making it impossible to maintain the adjusted grinding angle. Therefore, the first driving member 220 drives the first rotating shaft 210 to rotate relative to the first rotating frame 410, allowing the first roller brush 200 to maintain the required rotation angle for grinding, reducing the swaying amplitude of the first roller brush 200 during grinding, and improving grinding stability. When the telescopic component 400 drives the first roller brush 200 to move at one end connected to it, the first drive member 220 drives the first rotating shaft 210 to rotate as the end of the first roller brush 200 moves, so that the first roller brush 200 adapts to the rotation following the drive of the telescopic component 400, so that the axis of the first roller brush 200 and the axis of the second roller brush 300 can be kept at the desired grinding angle, which better adapts to the grinding surface of the irregular steel template.

[0037] Understandably, when the telescopic assembly 400 drives the second roller brush 300 to move at its connected end, the first rotating shaft 210 does not rotate under the action of the first driving member 220, so that the angle between the axis of the first roller brush 200 and the first rotating frame 410 remains unchanged. Then, under the action of the universal joint 500, the second roller brush 300 rotates relative to the first roller brush 200.

[0038] Optionally, the first rotating shaft 210 is horizontally positioned and passes through the axis of the first roller brush 200. This allows the first roller brush 200 to be adjusted vertically when driven by the telescopic assembly 400, so that the included angle between the first roller brush 200 and the second roller brush 300 can better adapt to irregularly shaped grinding surfaces.

[0039] Specifically, the first driving component 220 includes a first motor 221 and a support base 222. The first motor 221 is fixed to one side wall of the first rotating frame 410 via the support base 222, and the output end of the first motor 221 is fixedly connected to the first rotating shaft 210. In this way, the support base 222 provides support for the first motor 221, enabling the first motor 221 to drive the first rotating shaft 210 to rotate relative to the first rotating frame 410 more stably.

[0040] Optionally, the first roller brush 200 includes: a first connecting shaft 201, a first bushing 202, and a first brush cylinder 203. One end of the first connecting shaft 201 is connected to a universal joint 500; the first bushing 202 is rotatably connected to the other end of the first connecting shaft 201, and a first rotating shaft 210 is arranged through the first bushing 202 radially; the first brush cylinder 203 is sleeved on the outer peripheral wall of the first connecting shaft 201, and the inner peripheral wall of the first brush cylinder 203 is fixedly connected to the outer peripheral wall of the first connecting shaft 201. In this way, driving the first connecting shaft 201 to rotate on the bushing causes the first brush cylinder 203 to rotate, and the first connecting shaft 201 drives the second roller brush 300 to rotate through the universal joint 500, thereby polishing the grinding surface of the steel template. The first bushing 202 is provided to facilitate the rotational connection of the end of the first roller brush 200 to the first rotating frame 410 via the first rotating shaft 210, so that the first brush cylinder 203 can be vertically raised and lowered to adjust the grinding angle while rotating on its own axis.

[0041] Specifically, a sliding hole 204 adapted to the sliding rod 501 is provided on the inner side of the end of the first connecting shaft 201 that is connected to the universal joint 500. The sliding hole 204 extends upward along the axial direction of the first connecting shaft 201. In this way, the distance between the first connecting shaft 201 and the second roller brush 300 can be adjusted by the relative sliding of the sliding rod 501 and the sliding hole 204.

[0042] Specifically, both the sliding hole 204 and the sliding rod 501 have square cross-sections. This prevents relative rotation between the sliding hole 204 and the sliding rod 501. When the first connecting shaft 201 rotates, the second roller brush 300 is driven to rotate through the cooperation of the sliding hole 204 and the sliding rod 501 and the universal joint 500, resulting in more stable power transmission.

[0043] For example, when it is necessary to adjust the distance between the first roller brush 200 and the second roller brush 300, the distance between the two ends of the drive telescopic assembly 400 connected to the first roller brush 200 and the second roller brush 300 is increased. Under the action of the universal joint 500, the sliding rod 501 is pulled to slide relative to the sliding hole 204, thereby changing the distance between the first roller brush 200 and the second roller brush 300.

[0044] Optionally, the length of the sliding hole 204 along the axis of the first connecting shaft 201 is greater than or equal to one-third of the length of the first connecting shaft 201. This results in a relatively long sliding hole 204 and a relatively long sliding distance for the sliding rod 501, allowing the distance between the first roller brush 200 and the second roller brush 300 to be adjusted to a relatively large range, thereby increasing the polishing coverage of the first roller brush 200 and the second roller brush 300.

[0045] Specifically, the length of the sliding rod 501 is greater than or equal to the length of the sliding hole 204 along the axis of the first connecting shaft 201. Thus, the relatively long length of the sliding rod 501 and its relatively long sliding distance allow for adjustment of the distance between the first roller brush 200 and the second roller brush 300 to a relatively large range, thereby increasing the polishing coverage of the first roller brush 200 and the second roller brush 300.

[0046] Optionally, a shaft motor 230 is provided on one side of the first bushing 202, and the output end of the shaft motor 230 is connected to the first connecting shaft 201. In this way, the shaft motor 230 provides power for the rotation of the first connecting shaft 201, which drives the first brush cylinder 203 to rotate, and also drives the second roller brush 300 to rotate, thus polishing the grinding surface of the steel template.

[0047] Optionally, the lower end of the telescopic assembly 400 is provided with a second rotating frame 420. One end of the second roller brush 300 is rotatably connected to the second rotating frame 420 via a second rotating shaft 310, and the other end of the second roller brush 300 can perform circular motion around the second rotating shaft 310 as the center axis. This improves the stability of the rotatable connection between the end of the second roller brush 300 and the second rotating frame 420. When the telescopic assembly 400 drives the end of the second roller brush 300 to rise and fall, the second roller brush 300 can stably perform circular motion around the second rotating shaft 310 as the axis, forming an angle with the first roller brush 200.

[0048] Specifically, the end of the second roller brush 300 facing away from the first roller brush 200 is rotatably connected to the second rotating frame 420 via a second rotating shaft 310. The second roller brush 300 includes a second connecting shaft 301, a second bushing 302, and a second brush cylinder 303. One end of the second connecting shaft 301 is fixedly connected to a universal joint 500; the second bushing 302 is rotatably connected to the other end of the second connecting shaft 301, and the second rotating shaft 310 is arranged radially through the second bushing 302; the second brush cylinder 303 is sleeved on the outer peripheral wall of the second connecting shaft 301, and the inner peripheral wall of the second brush cylinder 303 is fixedly connected to the outer peripheral wall of the second connecting shaft 301. In this way, driving the second connecting shaft 301 to rotate on the second bushing 302 causes the first connecting shaft 201 to rotate via the universal joint 500, which in turn drives the second brush cylinder 303 to rotate, and the first brush cylinder 203 and the second brush cylinder 303 grind the grinding surface of the steel template. The second bushing 302 is provided to facilitate the rotational connection of the end of the second roller brush 300 to the second rotating frame 420 through the second connecting shaft 301, so that the second brush cylinder 303 can be vertically raised and lowered to adjust the grinding angle while rotating.

[0049] Optionally, the telescopic assembly 400 includes a first telescopic arm 430 and a second telescopic arm 440. The lower end of the first telescopic arm 430 is rotatably connected to the first roller brush 200; the lower end of the second telescopic arm 440 is rotatably connected to the second roller brush 300. Thus, the first telescopic arm 430 extends and retracts to drive the end of the first roller brush 200 connected to it to move; the second telescopic arm 440 extends and retracts to drive the end of the second roller brush 300 connected to it to move, allowing the telescopic assembly 400 to simultaneously or individually drive the ends of the first roller brush 200 and / or the second roller brush 300 to rise and fall, thereby adapting to grinding surfaces at different angles.

[0050] Specifically, the lower end of the first telescopic arm 430 is rotatably connected to the first roller brush 200 via the first rotating frame 410; the lower end of the second telescopic arm 440 is rotatably connected to the second roller brush 300 via the second rotating frame 420.

[0051] Optionally, the telescopic assembly 400 further includes a sliding frame 450. The upper ends of both the first telescopic arm 430 and the second telescopic arm 440 are slidably connected to the sliding frame 450. This allows both the first telescopic arm 430 and the second telescopic arm 440 to slide on the sliding frame 450, thereby moving the first roller brush 200 and the second roller brush 300 and adjusting their relative positions to the steel template in the horizontal direction. During the grinding process of the steel template, different areas on the steel template can be ground by adjusting the sliding positions of the first telescopic arm 430 and the second telescopic arm 440, without needing to adjust the position of the steel template, thus improving grinding efficiency.

[0052] For example, when the angle between the axis of the first roller brush 200 and the axis of the second roller brush 300 changes, the distance between the first roller brush 200 and the second roller brush 300 will change. By driving the first telescopic arm 430 or the second telescopic arm 440 to slide on the sliding frame 450, the distance between the first telescopic arm 430 and the second telescopic arm 440 can be adjusted to adapt to the change in the distance between the first roller brush 200 and the second roller brush 300.

[0053] Combination Figures 6 to 9 As shown, optionally, the first telescopic arm 430 includes: a first sliding seat 431, a first hydraulic cylinder 432, and a second driving member 433. The lower side wall of the first sliding seat 431 is fixedly connected to the first hydraulic cylinder 432. The first sliding seat 431 is slidably connected to the sliding frame 450; the output end of the first hydraulic cylinder 432 is connected to the first rotating frame 410; the second driving member 433 is disposed on one side wall of the first sliding seat 431, and the second driving member 433 meshes with the sliding frame 450. The second driving member 433 is used to drive the first sliding seat 431 to slide on the sliding frame 450. In this way, the second driving member 433 provides power for the first sliding seat 431 to slide on the sliding frame 450, thereby driving the first rotating frame 410 to move through the first hydraulic cylinder 432. The first hydraulic cylinder 432 extends and retracts, thereby driving the first rotating frame 410 and the end of the first roller brush 200 connected to the first rotating frame 410 to move, so that the axis of the first roller brush 200 and the axis of the second roller brush 300 form an angle that matches the angle of the grinding surface of the steel template. The first roller brush 200 and the second roller brush 300 then adhere to and grind the grinding surface of the steel template, improving the grinding effect, increasing grinding efficiency, and reducing the cost of grinding the steel template.

[0054] Optionally, the second telescopic arm 440 includes a second sliding seat 441 and a second hydraulic cylinder 442. The lower side wall of the second sliding seat 441 is fixedly connected to the second hydraulic cylinder 442. The second sliding seat 441 is slidably connected to the sliding frame 450; the output end of the second hydraulic cylinder 442 is connected to the second rotating frame 420. In this way, the second sliding seat 441 can slide on the sliding frame 450, and the extension and retraction of the second hydraulic cylinder 442 drives the second rotating frame 420 and the end of the second roller brush 300 connected to the second rotating frame 420 to move. The first roller brush 200 and the second roller brush 300 then adhere to and grind the grinding surface of the steel template, improving the grinding effect, increasing grinding efficiency, and reducing the cost of grinding the steel template.

[0055] Optionally, the telescopic assembly 400 further includes a telescopic member 460. One end of the telescopic member 460 is connected to the first telescopic arm 430, and the other end is connected to the second telescopic arm 440. Thus, the first telescopic arm 430 and the second telescopic arm 440 are connected via the telescopic member 460. The telescopic member 460 can extend and retract to adjust the distance between the first telescopic arm 430 and the second telescopic arm 440 to accommodate changes in the distance between the end of the first roller brush 200 connected to the first telescopic arm 430 and the end of the second roller brush 300 connected to the second telescopic arm 440. When the first telescopic arm 430 slides on the sliding frame 450, the telescopic member 460 can also drive the second telescopic arm 440 to move together.

[0056] Understandably, adjusting the distance between the first telescopic arm 430 and the second telescopic arm 440 allows the sliding rod 501 to slide within the sliding hole 204, thereby adjusting the distance between the first roller brush 200 and the second roller brush 300.

[0057] Optionally, the telescopic member 460 includes an extension rod 461 and a third hydraulic cylinder 462. One end of the third hydraulic cylinder 462 is connected to the first sliding seat 431; one end of the extension rod 461 is connected to the output end of the third hydraulic cylinder 462, and the other end of the extension rod 461 is connected to the second sliding seat 441. In this way, the third hydraulic cylinder 462 extends and retracts to adjust the distance between the first sliding seat 431 and the second sliding seat 441.

[0058] Optionally, the support frame 100 is provided with an annular guide rail 510 on its inner side, and both ends of the sliding frame 450 are engaged with the inner wall of the annular guide rail 510, so that the sliding frame 450 can rotate around the center of the annular guide rail 510 within the annular guide rail 510. In this way, the annular guide rail 510 can rotate within the sliding frame 450, and through the first telescopic arm 430 and the second telescopic arm 440, the first roller brush 200 and the second roller brush 300 are driven to rotate around the center of the annular guide rail 510, adjusting the angle of the first roller brush 200 and the second roller brush 300 relative to the steel template, so as to grind the steel template from different directions.

[0059] Optionally, each end of the sliding frame 450 is provided with a drive gear 451, which is rotatably connected to the sliding frame 450 and meshes with the inner sidewall of the annular guide rail 510. A third motor 452 is provided on one sidewall at each end of the sliding frame 450, and the output end of each third motor 452 is connected to a corresponding drive gear 451. In this way, the third motor 452 provides power to rotate the drive gear 451, and the drive gear 451, in cooperation with the inner side of the annular guide rail 510, drives the sliding frame 450 to rotate within the annular guide rail 510.

[0060] Specifically, an annular rack 511 is provided on the inner side of the annular guide rail 510, and each drive gear 451 meshes with the annular rack 511, and the annular rack 511 is slidably connected to both ends of the sliding frame 450. In this way, the stability of the connection is improved by the slidable connection between the annular rack 511 and both ends of the sliding frame 450.

[0061] Optionally, the support frame 100 is provided with a lead screw 520 and a guide rod 530 on its inner side.

Both ends of the lead screw 520 are rotatably connected to the support frame 100. The guide rod 530 is located on the other side of the annular guide rail 510 and is slidably connected to the outer wall of the annular guide rail 510. One end of the lead screw 520 is connected to the output end of the fifth motor 540, and the fifth motor 540 is connected to the support frame 100. In this way, the fifth motor 540 provides power for the rotation of the lead screw 520, which in turn drives the annular guide rail 510 to move. The annular guide rail 510 slides on the guide rod 530 and drives the first roller brush 200 and the second roller brush 300 to move through the sliding frame 450, the first telescopic arm 430 and the second telescopic arm 440. This allows the first roller brush 200 and the second roller brush 300 to grind the grinding surface of the steel template while moving, thereby improving grinding efficiency.

[0062] Specifically, the second driving component 433 includes a sixth motor 4331 and a rotating gear 4332. The gear meshes with the sliding frame 450; the sixth motor 4331 is connected to the first sliding frame 450, and the output end of the sixth motor 4331 meshes with the gear.

[0063] Optionally, the device for grinding steel templates further includes a clamping assembly 600 and a base 700. The base 700 is slidably connected to the clamping assembly 600. Thus, the base 700 provides support for the clamping assembly 600, and the clamping assembly 600 clamps the steel template. In conjunction with the grinding operations of the first roller brush 200 and the second roller brush 300, the clamping of the clamping assembly 600 reduces the slippage and sliding amplitude of the steel template, thereby improving the grinding effect.

[0064] Optionally, the clamping assembly 600 includes: a clamping base 610, a first clamping plate 620, and a second clamping plate 630. The bottom end of the clamping base 610 is slidably connected to the base 700; the first clamping plate 620 is slidably connected to the upper side wall of the clamping base 610; the second clamping plate 630 is slidably connected to the upper side wall of the clamping base 610, and the second clamping plate 630 and the first clamping plate 620 are symmetrically arranged. In this way, the first clamping plate 620 and the second clamping plate 630 are close to each other, thereby clamping and fixing the steel template, reducing the sliding and sliding range of the steel template, and improving the grinding effect.

[0065] Optionally, the first clamping plate 620 and the second clamping plate 630 are slidably connected to the clamping seat 610 via guide rails and slide grooves. One of the guide rails and slide grooves is provided on the clamping seat 610, and the other is provided on both the first clamping plate 620 and the second clamping plate 630. In this way, the first clamping plate 620 and the second clamping plate 630 are slidably connected to the clamping seat 610 via guide rails and slide grooves, which improves the connection stability between the first clamping plate 620 and the second clamping plate 630 and the clamping seat 610.

[0066] Optionally, an electric push rod 640 is provided on one side of the first clamping plate 620 and one side of the second clamping plate 630. Each electric push rod 640 is fixedly connected to the clamping seat 610, and the first clamping plate 620 and the second clamping plate 630 are connected to the output end of the corresponding electric push rod 640. In this way, the electric push rod 640 provides power for the movement of the first clamping plate 620 and the second clamping plate 630. The first clamping plate 620 and the second clamping plate 630 move closer to each other, thereby clamping and fixing the steel template, reducing the sliding and sliding range of the steel template, and improving the grinding effect.

[0067] Optionally, the base 700 includes a sliding arm 710 and a support plate 720. The sliding arm 710 is slidably connected to the clamping assembly 600; two support plates 720 are provided, respectively disposed at both ends of the sliding arm 710, to provide support for the sliding arm 710. The support plates 720 are disposed at both ends of the sliding arm 710, providing a relatively large support span and better support stability.

[0068] Specifically, the sliding arm 710 is provided with a groove 730, and the lower end of the clamping assembly 600 is slidably connected to the groove 730.
