Description

Technical Field

[0001] This utility model relates to the technical field of burr grinding equipment, specifically a burr grinding device for processing wear-resistant composite steel plates. Background Technology

[0002] After a steel plate is cut by a cutting machine, burrs, curls, dents and other defects are easily formed on the cut edges. Therefore, in the subsequent processing of steel plates, grinding tools are needed to grind away these defects.

[0003] According to a public notice (No. CN221088402U) of a burr grinding device for processing composite steel plates, the above application describes a clamping and positioning mechanism consisting of a first bidirectional lead screw, a connecting block, a clamping block, and a first motor, which can quickly achieve the clamping and positioning effect on the steel plate, thereby ensuring the stability of the steel plate processing.

[0004] However, in actual use, when grinding the surface of the steel plate, the large area of ​​the steel plate makes it difficult to control the contact tightness between the grinding wheel and the steel plate in a timely manner, which can easily lead to uncontrollable grinding force in different areas and reduce the processing quality of the steel plate. In view of this, we propose a burr grinding device for processing wear-resistant composite steel plates. Utility Model Content

[0007] A drive motor is fixedly mounted on the inner wall of a motor housing. A rotating rod is fixedly mounted on the output end of the drive motor. A sleeve is fitted on the arc-shaped outer wall of the rotating rod. A grinding wheel is fixedly mounted on the bottom end of the sleeve. A square rod is fixedly mounted on the top inner wall of the grinding wheel. A sleeve rod is fitted on the bottom outer wall of the square rod. A ball bearing is movably mounted on the bottom inner wall of the sleeve rod. A small spring is fixedly connected between the bottom end face of the square rod and the top inner wall of the sleeve rod.

[0008] A horizontal plate is fixedly installed on the top side wall of the sleeve rod. A top rod is fixedly installed on the upper surface of the horizontal plate. A fitting spring is fixedly connected between the bottom end face of the rotating rod and the bottom inner wall of the sleeve. One end of a pull rod is hinged to the top side wall of the top rod. An arc-shaped clamp is hinged to the other end of the pull rod. A limit cavity is formed in the bottom inner wall of the motor box.

[0009] Preferably, a strip block is provided on the arc-shaped outer wall of the rotating rod, and a strip groove adapted to the strip block is provided on the arc-shaped inner surface of the sleeve, so that the rotating rod and the sleeve can only be relatively displaced in the vertical direction, and there will be no relative rotation.

[0010] Preferably, the grinding wheel has a square cavity inside, the width of which is adapted to the width of the horizontal plate, thereby ensuring the stability of the horizontal plate and the sleeve rod during movement.

[0011] Preferably, the square rod, sleeve rod, and ball bearings are provided in two sets, and the two sets of square rod, sleeve rod, and ball bearings are mirror images of each other on both sides of the center of the grinding wheel, so that the grinding wheel will retract into the internal cavity of the grinding wheel when it comes into contact with the steel plate surface without obstructing it.

[0012] Preferably, the height of the arc-shaped clamp is adapted to the internal height of the limiting cavity, so that the arc-shaped clamp can only slide towards the sleeve side when pulled.

[0013] Preferably, the motor housing is provided with an auxiliary component, the auxiliary component is provided with a compression ring, the compression ring is fixedly installed on the bottom inner wall of the limiting cavity, a compression airbag is fixedly installed on the bottom arc-shaped inner surface of the arc-shaped clamping plate, an arc-shaped airbag is fixedly installed on the arc-shaped inner surface of the arc-shaped clamping plate, the arc-shaped airbag and the compression airbag are connected through each other, and the arc-shaped airbag and the compression airbag are filled with inert gas.

[0014] Preferably, the height of the compression ring is adapted to that of the compression airbag, and the arc-shaped airbag is inclinedly disposed on the arc-shaped outer surface of the arc-shaped clamp plate near the sleeve.

[0015] Compared with the prior art, this utility model provides a burr grinding device for processing wear-resistant composite steel plates, which has the following beneficial effects:

[0016] 1. This burr-removing device for processing wear-resistant composite steel plates is equipped with a locking component. After the bottom surface of the grinding wheel is in contact with the surface of the steel plate, the grinding wheel moves upward and compresses the contact spring. This ensures that the grinding wheel remains in contact with the surface of the steel plate during high-speed rotation. Consequently, the ball bearing drives the sleeve rod to move upward, and the cross plate drives the top rod to move upward. This, in turn, causes the pull rod and the arc-shaped clamping plate to slide closer to the sleeve. The arc-shaped clamping plate limits the height of the sleeve to prevent the grinding wheel from vibrating significantly in this position, thus ensuring the deburring effect of the grinding wheel.

[0017] 2. The burr grinding device for processing wear-resistant composite steel plates is equipped with auxiliary components. During the clamping process of the arc-shaped clamping plate near the sleeve, the extrusion ring squeezes the extrusion airbag, causing the arc-shaped airbag to expand. This increases the friction coefficient between the arc-shaped clamping plate and the sleeve, thereby ensuring the normal rotation of the sleeve while maintaining the height restriction effect within the limiting cavity, thus ensuring the device's burr grinding effect on the steel plate surface.

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a burr-removing device for processing wear-resistant composite steel plates, comprising a body 1, an adjusting frame 2 fixedly installed on the top of the body 1, a motor 3 fixedly installed on the side wall of the adjusting frame 2, a horizontal threaded rod 4 fixedly installed at the output end of the motor 3, a horizontal threaded sleeve 5 threadedly connected to the outer wall of the horizontal threaded rod 4, a motor 6 fixedly installed on the end side wall of the horizontal threaded sleeve 5, a longitudinal threaded rod 7 fixedly installed at the output end of the motor 6, and a vertical threaded sleeve 8 threadedly connected to the outer wall of the longitudinal threaded rod 7. A hydraulic telescopic column 9 is fixedly installed on the inner wall of the bottom end of the vertical threaded sleeve 8. A motor box 10 is fixedly installed at the bottom end of the hydraulic telescopic column 9. A locking assembly 11 is provided inside the motor box 10. The locking assembly 11 includes a drive motor 111, a rotating rod 112, a sleeve 113, a grinding wheel 114, a square rod 115, a sleeve rod 116, a ball bearing 117, a small spring 118, a horizontal plate 119, a top rod 1110, a contact spring 1111, a pull rod 1112, an arc-shaped clamping plate 1113, and a limiting cavity 1114.

[0025] In one embodiment of this utility model, a drive motor 111 is fixedly installed on the inner wall of a motor housing 10. A rotating rod 112 is fixedly installed at the output end of the drive motor 111. A sleeve 113 is fitted onto the arc-shaped outer wall of the rotating rod 112. A grinding wheel 114 is fixedly installed at the bottom end of the sleeve 113. A square rod 115 is fixedly installed on the top inner wall of the grinding wheel 114. A sleeve rod 116 is fitted onto the bottom outer wall of the square rod 115. A ball bearing 117 is movably installed on the bottom inner wall of the sleeve rod 116. The bottom end face of the square rod 115... A small spring 118 is fixedly connected to the top inner wall of the sleeve rod 116. A horizontal plate 119 is fixedly installed on the top side wall of the sleeve rod 116. A top rod 1110 is fixedly installed on the upper surface of the horizontal plate 119. A fitting spring 1111 is fixedly connected between the bottom end face of the rotating rod 112 and the bottom inner wall of the sleeve 113. One end of the pull rod 1112 is hinged to the top side wall of the top rod 1110. An arc-shaped clamping plate 1113 is hinged to the other end of the pull rod 1112. A limiting cavity 1114 is opened in the bottom inner wall of the motor box 10.

[0026] For further details, please refer to the instruction manual appendix. Figures 3-5The horizontal threaded rod 4 and the vertical threaded rod 7 are arranged perpendicularly to each other. At the same time, the horizontal threaded sleeve 5 is slidably connected to the inner surface of the adjusting frame 2 to guide and restrict the movement of the horizontal threaded sleeve 5. When the motor 1 3 drives the horizontal threaded rod 4 to rotate, the horizontal threaded sleeve 5 can move laterally along the inner wall of the adjusting frame 2. Similarly, the top outer wall of the vertical threaded sleeve 8 is slidably connected to the bottom outer wall of the horizontal threaded sleeve 5, so that the motor 1 3 and the motor 2 6 cooperate with each other, so that the horizontal threaded sleeve 5 and the vertical threaded sleeve 8 can drive the motor box 10 to adjust its position relatively freely on the upper surface of the machine body 1, so as to perform burr grinding work on various positions of the steel plate placed on the upper surface of the machine body 1. In addition, the upper surface of the machine body 1 is provided with a positioning unit, which can position and restrict the steel plate to be processed placed on the machine body 1, thereby avoiding vibration or displacement during the burr grinding process.

[0027] Meanwhile, ventilation holes are provided on the side wall of the motor housing 10 to ensure the normal operation and heat dissipation of the drive motor 111. In addition, a strip block is provided on the arc-shaped outer wall of the rotating rod 112, and a strip groove adapted to the strip block is provided on the arc-shaped inner surface of the sleeve 113, so that the rotating rod 112 and the sleeve 113 can only have relative displacement in the vertical direction, and there will be no relative rotation. Specifically, while the drive motor 111 drives the rotating rod 112 to rotate, the sleeve 113 and the rotating rod 112 rotate in the same direction and at the same speed. Furthermore, the grinding wheel 114 has a square cavity inside, the width of which is adapted to the width of the horizontal plate 119, thereby ensuring the stability of the horizontal plate 119 and the sleeve rod 116 during movement. In addition, through the setting of the contact spring 1111, the grinding wheel 114 will move upward during the process of contacting the surface of the steel plate, and compress the contact spring 1111, so as to ensure that the grinding wheel 114 always contacts the surface of the steel plate during high-speed rotation, thereby ensuring the grinding quality of the burrs on the surface of the steel plate.

[0028] Specifically, there are two sets of square rods 115, sleeve rods 116, and ball bearings 117, and the two sets of square rods 115, sleeve rods 116, and ball bearings 117 are mirror images of each other on both sides of the center of the grinding wheel 114. This allows the grinding wheel 114 to retract into its internal cavity when it contacts the steel plate surface without obstructing it. At the same time, rectangular grooves with a width matching the width of the pull rod 1112 are provided on the inner walls of the left and right sides of the rotating rod 112. Thus, during the process of the sleeve rod 116 retracting into the interior of the grinding wheel 114, the horizontal plate 119 drives the push rod 11 10 moves upward, which in turn causes the pull rod 1112 and the arc-shaped clamp 1113 to slide closer to the sleeve 113. The height of the arc-shaped clamp 1113 is matched with the internal height of the limiting cavity 1114, so that when the arc-shaped clamp 1113 is pulled, it can only slide towards the sleeve 113. This allows the bottom surface of the grinding wheel 114 to be in contact with the surface of the steel plate. The height of the sleeve 113 is limited by the arc-shaped clamp 1113 to ensure that the grinding wheel 114 will not vibrate significantly in this position, thus affecting the deburring and grinding effect of the grinding wheel 114.

[0029] In addition, an auxiliary component 12 is provided inside the motor housing 10. A compression ring 121 is provided inside the auxiliary component 12. The compression ring 121 is fixedly installed on the bottom inner wall of the limiting cavity 1114. A compression airbag 122 is fixedly installed on the bottom arc-shaped inner surface of the arc-shaped clamping plate 1113. An arc-shaped airbag 123 is fixedly installed on the arc-shaped inner surface of the arc-shaped clamping plate 1113. The arc-shaped airbag 123 and the compression airbag 122 are connected through each other. The interiors of the arc-shaped airbag 123 and the compression airbag 122 are filled with inert gas.

[0030] In this embodiment of the invention, the height of the compression ring 121 is matched with that of the compression airbag 122, and the arc-shaped airbag 123 is inclinedly disposed on the arc-shaped outer surface of the arc-shaped clamping plate 1113 near the sleeve 113. During the clamping process of the arc-shaped clamping plate 1113 near the sleeve 113, the compression ring 121 compresses the compression airbag 122, causing the arc-shaped airbag 123 to expand, thereby increasing the friction coefficient between the arc-shaped clamping plate 1113 and the sleeve 113. This ensures the normal rotation of the sleeve 113 while maintaining the height restriction effect within the limiting cavity 1114, thereby ensuring the device's effect on burr removal from the steel plate surface.

[0031] In this invention, during use, the steel plate is fixed to the upper surface of the machine body 1 by the positioning unit on the machine body 1. At this time, by controlling motor 3 and motor 6, the horizontal threaded sleeve 5 and the vertical threaded sleeve 8 cooperate to drive the motor box 10 to perform relatively free position adjustment on the upper surface of the machine body 1, so as to perform burr grinding work on various positions on the surface of the steel plate placed on the upper surface of the machine body 1. At the same time, by providing locking component 11, after the bottom surface of the grinding wheel 114 is in contact with the surface of the steel plate, the grinding wheel 114 will move upward. The spring 1111 is compressed to ensure that the grinding wheel 114 remains in contact with the surface of the steel plate during high-speed rotation. This causes the ball bearing 117 to drive the sleeve rod 116 to move upward, and the horizontal plate 119 to drive the top rod 1110 to move upward. This, in turn, causes the pull rod 1112 and the arc-shaped clamping plate 1113 to slide near the sleeve 113. The arc-shaped clamping plate 1113 restricts the height of the sleeve 113 to ensure that the grinding wheel 114 does not vibrate significantly in this position, thus affecting the deburring and grinding effect of the grinding wheel 114.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
