Description

Technical Field

[0001] The utility model belongs to the technical field of axial weld processing of cylindrical parts, and particularly relates to a device for flattening the axial weld of cylindrical parts. Background Art

[0002] A common manufacturing process for aluminum alloy cylinders is to use aluminum alloy sheet in a rounding machine. The entire manufacturing process primarily involves rounding and welding. This method offers high forming efficiency, a wide range of product types, and strong adaptability. Currently, cylindrical parts manufactured from aluminum alloy sheet primarily include unribbed and ribbed cylindrical parts. Figure 1 It is a cylindrical part without ribs, and the cylindrical part without ribs consists of a circular surface 11, a flat surface 12 and a weld 13 located in the middle of the flat surface 12; Figure 2 The ribbed cylindrical part is composed of a circular surface 11 , ribs 14 arranged on the inner circumference of the circular surface 11 , and a weld 13 located on the surface of the circular surface 11 .

[0003] When manufacturing cylindrical parts using aluminum alloy plates through rounding, the mating surfaces often become uneven after the rounding process. This condition is not conducive to subsequent welding of the parts. Therefore, the mating surfaces must be flattened before welding to achieve a weld profile that meets the requirements of the welding process. The traditional method involves cutting and leveling the weld seam. However, this process is currently performed primarily manually, resulting in low efficiency and inability to guarantee the quality of the weld seams on cylindrical parts. Utility Model Content

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 3 to 7 As shown, an embodiment of the utility model provides a device for cutting the axial weld of a cylindrical part, which specifically includes a frame assembly 1 for fixedly supporting the entire device, a support assembly 2 for supporting and positioning the cylindrical part is fixedly installed on one side of the frame assembly 1, a clamping assembly 3 for fixing and clamping the cylindrical part is fixedly installed on the side opposite to the support assembly 2, a positioning assembly 4 for initially positioning and leveling the weld 1.3 of the cylindrical part is fixedly arranged on the upper part of the support assembly 2, and a cutting assembly 5 for sawing the weld 1.3 of the cylindrical part is connected to the top of the frame assembly 1.

[0034] Specifically, in this embodiment, during operation, a cylindrical part is placed on the support assembly 2, and then the positioning assembly 4 is activated to descend, inserting the positioning strip 4.4 in the positioning assembly 4 into the weld 13 on the cylindrical part. The cylindrical part is then pressed against the positioning mounting plate 4.3 in the positioning assembly 4 to achieve radial positioning of the part and circumferential positioning of the weld. The clamping assembly 3 is then activated to tightly press the axial end face of the cylindrical part against the side end face of the support assembly 2 to clamp the part. After the part is clamped, the positioning assembly 4 is activated to ascend and separate from the part, and finally the cutting assembly 5 is activated to saw the weld. This greatly improves the efficiency of cylindrical part weld processing, enabling automatic deburring and leveling of the cylindrical part weld, ensuring stable, accurate, and efficient weld quality.

[0035] See also Figure 1 As shown, the frame assembly 1 specifically includes a fixed frame 1.1, an intermediate bracket 1.2 fixedly connected to one side of the interior of the fixed frame 1.1, a clamping support 1.3 fixedly mounted between the intermediate bracket 1.2 and the fixed frame 1.1, and a clamping assembly 3 fixedly mounted to the top of the clamping support 1.3. In this embodiment, the fixed frame 1.1 is entirely made of steel and has a rectangular parallelepiped structure. The fixed frame 1.1 serves as the supporting skeleton of the entire device. The intermediate bracket 1.2 is fixedly connected to the right side of the interior of the fixed frame 1.1, and the clamping support 1.3 is fixedly connected between the left side of the intermediate bracket 1.2 and the bottom of the fixed frame 1.1, thereby supporting and fixing the clamping support 1.3.

[0036] See also Figure 1 and Figure 5 As shown, the support assembly 2 specifically includes a support base 2.1 for fixing the support assembly 2. The support base 2.1 is fixedly mounted on the lower left side of the frame assembly 1.

A positioning support block 2.3 is provided on the outer side of the positioning support frame 2.2. A positioning groove 2.4 is opened in the middle of the positioning support block 2.3 along the horizontal direction to match the weld of the cylindrical part. In this embodiment, when in use, the cylindrical part is placed on the positioning support frame 2.2, and the position of the weld on the cylindrical part is aligned with the opening of the positioning groove 2.4. The positioning assembly 4 is then lowered to position and press the cylindrical part to achieve vertical compression and positioning of the cylindrical part. The clamping assembly 3 is then activated to clamp and position the cylindrical part horizontally. In this way, the positioning assembly 4, the support assembly 2, and the clamping assembly 3 can achieve fixed support of the cylindrical part to ensure stability of subsequent processing.

[0037] See also Figure 5As shown, this embodiment is further optimized. The positioning support frame 2.2 specifically includes a horizontal fixing plate 2.21, a vertical fixing plate 2.22 is fixedly connected to the right side of the horizontal fixing plate 2.21, a reinforcing plate 2.23 is connected between the horizontal fixing plate 2.21 and the vertical fixing plate 2.22, the bottom of the horizontal fixing plate 2.21 is fixedly connected to the support base 2.1, and the vertical fixing plate 2.22 is connected to one side of the positioning support block 2.3. In this way, the reinforcing plate 2.23 can ensure the stability of the connection between the horizontal fixing plate 2.21 and the vertical fixing plate 2.22, and can also facilitate the replacement and disassembly of the positioning support frame 2.2 as a whole. A connecting groove 2.24 that matches the positioning groove 2.4 is provided at the bottom of the vertical fixing plate 2.22. The connecting groove 2.24 has the same width as the top of the positioning groove 2.4, which can prevent interference with the vertical fixing plate 2.22 when the positioning assembly 4 is working.

[0038] See also Figure 4 As shown, the clamping assembly 3 specifically includes a clamping cylinder 3.1, to which a horizontal movable plate 3.2 is fixedly connected via a connecting block at the telescopic end of the clamping cylinder 3.1. A clamping plate 3.3 is fixedly connected to the side of the horizontal movable plate 3.2 close to the support assembly 2. During use, the clamping cylinder 3.1 drives the horizontal movable plate 3.2 to move to the left, tightly clamping the cylindrical part on the positioning support block 2.3. An interference gap 3.4 is provided at the top of the clamping plate 3.3, which matches the bottom of the saw blade 5.43. In this way, when the cutting assembly 5 is in operation, interference between the saw blade 5.43 and the clamping plate 3.3 can be ensured, thereby preventing interference between the clamping assembly 3 and the cutting assembly 5 during operation.

[0039] See also Figure 6As shown, the positioning assembly 4 specifically includes a positioning connecting plate 4.1, which is fixedly connected to the top of the frame assembly 1 to ensure the stability of the positioning assembly 4 during operation.

During operation, the positioning cylinder 4.2 drives the positioning rod 4.4 upward and downward. As the positioning cylinder 4.2 drives the positioning rod 4.4 downward, the positioning rod 4.4 is inserted into the weld seam 1.3 of the cylindrical component to position the cylindrical component. The clamping assembly 3 is then activated to tighten and secure the cylindrical component. Once the cylindrical component is clamped and secured, the positioning cylinder 4.2 rises and separates from the cylindrical component. Further optimizing this embodiment, guide sleeves 4.5 are fixedly connected to both sides of the positioning cylinder 4.2 on the positioning connecting plate 4.1. Guide rods 4.6 are slidably connected within the guide sleeves 4.5. The front ends of the guide rods 4.6 are connected to the positioning connecting plate 4.1. The provision of the guide sleeves 4.5 and guide rods 4.6 ensures the stability and smoothness of the positioning assembly 4 during operation. Positioning insert 4.4 specifically comprises a rectangular insert 4.41 and a wedge-shaped insert 4.42. Rectangular insert 4.41 is fixedly mounted to the bottom of positioning mounting plate 4.3, while wedge-shaped insert 4.42 is fixedly connected to the bottom of rectangular insert 4.41. Rectangular insert 4.41 and wedge-shaped insert 4.42 form an integrally formed structure. In this embodiment, wedge-shaped insert 4.42 has a trapezoidal structure, narrow at the bottom and wide at the top. This trapezoidal design ensures that when wedge-shaped insert 4.42 is inserted into weld 1.3 of the cylindrical component, the cylindrical component is pressed more and more tightly as positioning cylinder 4.2 drives positioning insert 4.4 downward.
