Description

Technical Field

[0001] This invention relates to the field of sheet metal processing, and in particular to a cross-shaped sheet metal cleaning machine. Background Technology

[0002] Angle steel, channel steel, or other plates often require welding during use due to environmental requirements. To ensure proper fit with other workpieces, the welded workpieces need to have specific angles, such as 45, 60, or 90 degrees. However, due to the solder, the weld may become arc-shaped or irregular, preventing the workpiece's angle from fitting precisely with other workpieces. Therefore, the welded workpieces require root cleaning.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the invention and are not intended to limit the invention.

[0028] See Figure 2 The present invention provides a cross-plate root cleaning machine, which includes a main frame 001, a lower bracket 100 and an upper bracket 200 installed on the main frame 001 and correspondingly arranged on the upper and lower sides.

[0029] An inclined cutter head 2 is installed at a predetermined position in the middle of the lower bracket 100. Figure 4 and Figure 5 As shown, the cutter head 2 is mounted on the cutter head bracket 1; the upper end of the lower support 100 is provided with several support rollers 4 to support the workpiece. The support rollers 4 are arranged in a straight line along the radial direction of the cutter head 2. When the cutter head 2 is cleaning the workpiece, the support rollers 4 are used to support the workpiece and cooperate with the drive gear 5 (described in detail below) to drive the workpiece to form a transmission; the cutter head bracket 1 is equipped with a cutter head drive mechanism to drive the cutter head 2 to rotate; see Figure 7In this example, the cutter head drive mechanism includes a rotating shaft 41 with its end coaxially fixed to the cutter head 2, and a cutter head drive motor 42 fixedly installed on the cutter head bracket 1 and driving the rotating shaft 41 to rotate. The cutter head bracket 1 is provided with a support sleeve 43 supporting the rotating shaft 41, and the rotating shaft 41 is rotatably installed within the support sleeve 43. The support shaft 41 is fixedly connected to the output end of the cutter head drive motor 42. When driving the cutter head 2 to rotate, the cutter head drive motor 42 is started, driving the rotating shaft 41 to rotate and further driving the cutter head 2 to rotate. The rotating cutter head 2 uses its outer circumference to perform root cleaning work on the cross-shaped connecting plate.

[0030] See Figure 2 and Figure 3 To facilitate workpiece loading (making it easy to place materials between the upper bracket 200 and the lower bracket 100), a lifting assembly is provided between the upper bracket 200 and the main frame 001 to drive the upper bracket 200 to move up and down in the vertical direction. When it is necessary to unload the material, the lifting assembly drives the upper bracket 200 to rise a predetermined distance. After unloading, the lifting assembly drives the upper bracket 200 to descend and reset. The lifting assembly includes a rack 101 fixedly installed on the main frame 001, a lifting motor 201 installed on the upper bracket 200, and a meshing gear 202 installed at the output end of the lifting motor 201 and meshing with the rack 101. A support shaft 203 is installed at the output end of the lifting motor 201, and the lifting motor 201 is installed on the support shaft 203. When the lifting assembly is in the upward operation, the lifting motor 201 starts and drives the meshing gear 202 to rotate in the forward direction. The rotating meshing gear 202 meshes with the rack 101 and drives the upper bracket 200 to rise. When the lifting assembly is in the downward operation, the lifting motor 201 starts and drives the meshing gear 202 to rotate in the reverse direction. The rotating meshing gear 202 meshes with the rack 101 and drives the upper bracket 200 to descend.

[0031] See Figure 6 The lower end of the upper bracket 200 is equipped with a plurality of drive gears 5 that drive the workpiece to move along the distribution direction of the support rollers 4. The plurality of drive gears 5 and the plurality of support rollers 4 have the same arrangement structure. The drive gears 5 are driven to rotate by a gear structure. The gear structure includes a gear drive motor (not shown in the figure) mounted on the upper bracket 200, a first gear 22 mounted on the output end of the gear drive motor, and a transition gear 23 connecting the first gear 22 and the drive gears 5. When the drive gears 5 rotate, the gear drive motor is activated, the gear drive motor drives the first gear 22 to rotate, the rotating first gear 22 drives the transition gear 23 to rotate, and further drives the drive gears 5 to rotate.

[0032] Both the lower support bracket 100 and the upper support bracket 200 are equipped with a plurality of inclined auxiliary support rollers 6 for assisting in the positioning of the workpiece. The auxiliary support rollers 6 on the lower support bracket 100 are symmetrically distributed on the left and right sides of the lower support bracket 100. The auxiliary support rollers 6 are rotatably mounted on support roller brackets 61, which are fixedly mounted on the lower support bracket 100. An angle A is formed between the auxiliary support rollers 6 on the left and right sides, corresponding to the angle of the cross plate. The auxiliary support rollers 6 provide positioning support for the cross plate, preventing angular displacement after the cross plate is placed on the support rollers 4, which could lead to contact between the end face of the cutter head and the plate surface, causing machining errors. The auxiliary support rollers 6 on the upper support bracket 200 and the auxiliary support rollers 6 on the lower support bracket 100 have a symmetrical structure.

[0033] See Figure 4 , Figure 5 and Figure 9 The cutter head support is equipped with a guard plate 3; the guard plate 3 has a supporting convex surface 31; along the axis of the cutter head 2 and in the direction close to the workpiece, there is a distance H between the supporting convex surface 31 and the surface of the cutter head 2, which is 3 to 7 cm. The supporting convex surface 31 supports the workpiece surface, ensuring that there is at least a gap H between the surface of the cutter head 2 and the workpiece, preventing contact between the surface of the cutter head 2 and the surface of the cross-shaped connecting plate, thus preventing scratches.

[0034] See Figure 8 Preferably, the supporting convex surface 31 of the present invention is a plane or a curved surface. In this example, the supporting convex surface 31 is a planar structure, which adapts to the shape of the cross-shaped connecting plate on the one hand, and avoids stress concentration inside the cross-shaped connecting plate when supporting the plate surface on the other hand. The outer edge tangent of the auxiliary supporting roller 6 is coplanar with the supporting convex surface 31, so that the auxiliary supporting roller 6 and the supporting convex surface 31 play a joint supporting role.

[0035] Furthermore, the supporting convex surface 31 of the present invention is provided with an embedding groove 311; the cutter head 2 is placed in the embedding groove 311. By setting the embedding groove 311, the fit between the supporting convex surface 31 and the cutter head 2 is optimized, while reducing the space occupied by the supporting convex surface 31. The embedding groove 311 is a circular or polygonal structure. In this example, the embedding groove 311 is circular, further improving the fit between the supporting convex surface 31 and the cutter head 2.

[0036] Furthermore, the guard plate 3 of the present invention is mounted on the cutter head support 1 via a positioning mechanism; under the action of the positioning mechanism, the guard plate 3 can be moved and adjusted in the axial direction of the cutter head 2, thereby changing the size of the distance H. In this example, the guard plate 3 also has a support plate surface 32; the positioning mechanism includes a positioning groove 321 provided on the support plate surface 32 and a bolt 322 installed in the positioning groove 321. The positioning groove 321 is a strip-shaped groove, and the end of the bolt 322 is screwed to the cutter head support 1. During adjustment, first loosen the bolt 322, move the guard plate 3 to the predetermined position, and finally tighten the bolt 322.

[0037] In summary, this invention provides a cross-plate root cleaning machine, comprising a main frame, a lower support and an upper support mounted on the main frame and correspondingly arranged vertically; an inclined cutter disc is installed at a predetermined position in the middle of the lower support, the cutter disc being mounted on a cutter disc bracket; a plurality of support rollers for supporting the workpiece are provided at the upper end of the lower support, the plurality of support rollers being arranged in a straight line along the radial direction of the cutter disc, the support rollers supporting the workpiece and cooperating with the drive gear to drive the workpiece to form a transmission when the cutter disc performs root cleaning work; a cutter disc drive mechanism for driving the cutter disc to rotate is installed inside the cutter disc bracket; the cutter disc drive mechanism includes a rotating shaft whose end is coaxially fixed to the cutter disc and a cutter disc drive motor fixedly installed on the cutter disc bracket and driving the rotating shaft to rotate; a support sleeve for supporting the rotating shaft is provided on the cutter disc bracket, the rotating shaft being rotatably installed in the support sleeve; the support rotating shaft is fixedly connected to the output end of the cutter disc drive motor. When the cutter head rotates, the cutter head drive motor is activated. The cutter head drive motor drives the rotating shaft to rotate, which in turn drives the cutter head to rotate. The rotating cutter head uses its outer circumference to perform root cleaning work on the cross plate. This invention can use auxiliary support rollers and guard plates to jointly support the cross plate, which facilitates the positioning and support of the workpiece and prevents the workpiece from being affected by angular displacement. On the other hand, it prevents the end face of the cutter head from contacting the plate surface, thus avoiding scratches on the plate surface.
