Description

Technical Field

[0001] This utility model relates to the field of steel plate processing technology, specifically to a burr-removing device for steel plate processing. Background Technology

[0002] With the rapid development of modern industry, steel plates have been widely used in construction, machinery manufacturing, automobiles and other industries. During the processing of steel plates, burrs are an unavoidable problem. They not only affect the appearance quality of the product, but may also pose safety hazards to subsequent processing and use. Therefore, it is crucial to effectively grind burrs off steel plates.

[0003] Patent CN219337133U discloses a deburring device for steel plate processing, including a processing table. A fixing block is fixed to one end of the upper surface of the processing table, and a grinding wheel is mounted on the side of the fixing block facing the center of the processing table.

A fixing mechanism is provided on the processing table, including a first base and a second base disposed on the upper surface of the processing table. A turntable is rotatably mounted on the upper surface of the first base, and a slide is slidably mounted on the upper surface of the second base. Clamping components are provided on both the slide and the turntable. This device allows adjustment of the grinding angle of the steel plate during deburring, effectively removing burrs from the end face and edges of the steel plate. It also facilitates the formation of chamfers on the end edges of the steel plate, which is beneficial for further processing of the steel plate.

[0004] However, the steel plate burr grinding device in the above technology still has the following problems: when processing disc-shaped steel plates, because the outer edge of the disc-shaped steel plate has an arc-shaped structure, the grinding wheel cannot make uniform contact with the edge of the disc-shaped steel plate, and the outer edge of the disc-shaped steel plate cannot be ground.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Please see Figures 1 to 7A burr-removing device for steel plate processing includes a processing table 1. A rotary motor 2 is fixedly connected to the bottom of one end of the processing table 1. The output axis of the rotary motor 2 passes through the processing table 1 and is fixedly connected to a rotary table 3. An L-shaped support frame 4 is connected to the end of the processing table 1 away from the rotary table 3. The other end of the L-shaped support frame 4 extends above the rotary table 3 and is connected to a pressing component 5. An adjustment component 6 is connected to the end of the L-shaped support frame 4 away from the rotary table 3. A grinding wheel 7 is connected to the end of the adjustment component 6 close to the rotary table 3.

[0028] like Figures 1 to 7 As shown, the main improvement of this utility model lies in improving the grinding effect on the outer edge of the disc-shaped steel plate, such as... Figures 1 to 7 As shown, in use, the steel plate deburring device of this utility model involves placing a disc-shaped steel plate on a rotating table 3 and aligning the center of the disc-shaped steel plate with the center of the rotating table 3. Then, the disc-shaped steel plate is fixed on the rotating table 3 by pressing down the pressing component 5. Finally, the grinding wheel 7 is driven to approach the edge of the disc-shaped steel plate by the adjusting component 6. Then, the rotating motor 2 is started to drive the disc-shaped steel plate to rotate. At this time, the edge of the rotating disc-shaped steel plate can generate uniform friction with the grinding wheel 7, thereby improving the deburring effect of the edge of the disc-shaped steel plate.

[0029] like Figure 1 and Figure 5 As shown, the pressing assembly 5 includes a pressing cylinder 51 and a pressing plate 52. The pressing cylinder 51 is fixedly connected to the side of the L-shaped support frame 4 away from the rotary table 3, and the pressing cylinder 51 is located directly above the rotary table 3. The telescopic end of the pressing cylinder 51 passes downward through the L-shaped support frame 4 and is connected to a rotating mechanism 8. The rotating mechanism 8 is connected to the pressing plate 52, and the central axis of the pressing plate 52 rotates through the rotating mechanism 8 and coincides with the central axis of the rotary table 3. When pressing down to fix the disc steel plate, the pressing cylinder 51 drives the pressing plate 52 to move down and abut against the upper surface of the disc steel plate. Together with the rotary table 3 at the bottom, the disc steel plate is pressed and fixed. When the rotary table 3 rotates, the pressing plate 52 rotates below the pressing cylinder 51 and follows the rotary table 3 to rotate, so that the rotary grinding operation can be carried out smoothly.

[0030] like Figure 1 and Figure 5As shown, the rotating mechanism 8 includes a connecting block 81 and a T-shaped block 82. The connecting block 81 is fixedly connected to the side of the lower pressure plate 52 away from the rotary table 3. A T-shaped rotating hole 801 is provided on the side of the connecting block 81 away from the rotary table 3. The T-shaped block 82 is rotatably connected to the T-shaped rotating hole 801. The end of the T-shaped block 82 away from the T-shaped rotating hole 801 is fixedly connected to the telescopic end of the lower pressure cylinder 51. The connecting block 81 rotates with the lower pressure plate 52, while the T-shaped block 82 remains stationary connected to the lower pressure cylinder 51. It should be noted that the connection between the T-shaped block 82 and the T-shaped rotating hole 801 can be replaced by a bearing. Using a bearing can reduce the friction between the T-shaped block 82 and the T-shaped rotating hole 801 during rotation.

[0031] like Figure 1 As shown, an anti-slip pad 31 is fixedly connected to the upper surface of the rotary table 3. The anti-slip pad 31 makes contact with the disc steel plate on the rotary table 3, which can increase the contact friction between the disc steel plate and the rotary table 3, prevent the centrifugal force generated when the rotary table 3 rotates from throwing the disc steel plate off, and improve the stability of the disc steel plate during the grinding operation on the rotary table 3.

[0032] like Figure 6 and Figure 7 As shown, the bottom of the rotary table 3 has several ball holes 301, which are evenly distributed circumferentially on the bottom of the rotary table 3. Each ball hole 301 has an auxiliary ball 32 rotatably connected to it, and the bottom of each auxiliary ball 32 is slidably connected to the upper surface of the processing table 1. When the rotary table 3 rotates for grinding, the multiple auxiliary balls 32 at the bottom support the rotary table 3 on the processing table 1, improving the stability of the rotary table 3's rotation on the processing table 1 and reducing the friction between the rotary table 3 and the processing table 1, thus making the rotation of the rotary table 3 smoother and improving the stability of the grinding operation.

[0033] like Figures 1 to 4 As shown, the adjustment assembly 6 includes an electric actuator 61 and a U-shaped frame 62. The electric actuator 61 is fixedly connected to the side of the L-shaped support frame 4 away from the rotary table 3. The telescopic end of the electric actuator 61 passes through the L-shaped support frame 4 and is fixedly connected to the U-shaped frame 62. The upper and lower ends of the grinding wheel 7 are respectively connected to the two ends of the U-shaped frame 62. The grinding wheel 7 is installed on the inner side of the U-shaped frame 62. By controlling the U-shaped frame 62 to move closer to the disc steel plate on the rotary table 3 through the electric actuator 61, the grinding wheel 7 can contact the outer edge of the disc steel plate. This allows for the grinding of burrs on the edges of disc steel plates of different diameters, improving the applicability of the grinding device.

[0034] like Figures 1 to 4As shown, a sliding groove 101 is provided through the side of the processing table 1 adjacent to the L-shaped support frame 4. The two ends of the U-shaped frame 62 are slidably connected to the two sliding grooves 101 respectively. The upper and lower ends of the U-shaped frame 62 are slidably connected to the sliding grooves 101 on the inner side of the processing table 1 and the L-shaped support frame 4. This can prevent the U-shaped frame 62 from tilting laterally when the grinding wheel 7 is subjected to lateral force during grinding operations, improve the stability of the grinding operation, and ensure that the outer side of the grinding wheel 7 always presses against the outer edge of the disc steel plate for burr grinding.

[0035] like Figures 1 to 4 As shown, limit grooves 102 are provided on both sides of the slide 101, and limit blocks 63 are fixedly connected to both sides of the end of the U-shaped frame 62. The limit blocks 63 are slidably connected to the limit grooves 102. By limiting the movement of the limit blocks 63 and the limit grooves 102 on the inner side of the slide 101, the U-shaped frame 62 can be prevented from shaking up and down, thus improving the stability of the U-shaped frame 62 in adjusting and moving between the processing table 1 and the L-shaped support frame 4.

[0036] like Figures 1 to 7 As shown, a grinding motor 9 is fixedly connected to the bottom of the U-shaped frame 62. The output end of the grinding motor 9 passes through the U-shaped frame 62 and is fixedly connected to a drive block 10. A drive groove 701 is provided at the bottom of the grinding wheel 7. The drive block 10 is slidably connected to the drive groove 701. A positioning component 11 is connected to the top of the U-shaped frame 62 near the grinding wheel 7. The positioning component 11 is connected to the end of the grinding wheel 7 away from the drive groove 701. The grinding wheel 7 can be mounted on the drive block 10 through the drive groove 701 and is driven by the grinding motor 9 to rotate rapidly inside the U-shaped frame 62. This allows the high-speed rotating grinding wheel 7 to achieve a better grinding effect on the outer edge of the disc steel plate, while improving grinding efficiency.

[0037] like Figures 1 to 7 As shown, the positioning assembly 11 includes a limiting rod 12, a compression spring 13, and a positioning block 14. The end of the grinding wheel 7 away from the drive groove 701 has a positioning hole 702. The positioning block 14 is rotatably connected to the positioning hole 702. The side of the positioning block 14 away from the grinding wheel 7 is fixedly connected to the limiting rod 12. The other end of the limiting rod 12 passes through the U-shaped frame 62 upward and is slidably connected to the U-shaped frame 62. The compression spring 13 is sleeved on the outside of the limiting rod 12. One end of the compression spring 13 is fixedly connected to the positioning block 14, and the other end is fixedly connected to the U-shaped frame 62. After the grinding wheel 7 is installed on the drive block 10, the positioning block 14 is pressed into the positioning hole 702 by the compression spring 13, and the top of the grinding wheel 7 is limited by the limiting rod 12 to ensure that the grinding wheel 7 will not move upward and fall out of the U-shaped frame 62 during rapid rotation. It should be noted that the positioning block 14 can be replaced by a bearing to reduce the friction between the grinding wheel 7 and the positioning block 14 during rotation, so that the grinding wheel 7 can rotate more smoothly.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
