Technical Field

[0001] This utility model belongs to the field of welding tooling technology, specifically relating to a cylindrical welding tooling. Background Technology

[0002] It is necessary to weld tool or hammer mounting seats at specific angles around the circumference of the cylinder to achieve the cutting and crushing function of materials through rotation. Previously, a V-block was used to position the central axis of the cylinder, calipers were used to measure and mark lines, and standard blocks were welded for positioning. Then, measurements were taken and adjustments were made, and finally, the mounting seats were welded to the cylinder. To ensure the concentricity of the outer edge of the mounting seat with the cylinder and to meet the dynamic balance requirements of the cylinder, a high level of experience and skill is required from the operator.

[0003] The existing cylindrical welding fixtures have the following drawbacks during use: they rely on employee skills and inspection to ensure small-batch production, which greatly reduces production efficiency. Therefore, a new cylindrical welding fixture is needed. Utility Model Content

[0007] In a preferred embodiment, the vertical cross-section of the first fixing ear plate is larger than that of the second fixing ear plate.

[0008] In a preferred embodiment, the first fixing component includes a plurality of equidistant first mounting holes formed on the outer wall of the tooling body, wherein a first bolt is movably inserted into one of the first mounting holes, and the first bolt is engaged with two first washers and threadedly connected with a first nut to fix the positioning box on the tooling body.

[0009] In a preferred embodiment, the second fixing component includes two second mounting holes formed on the outer wall of the tooling body. A second bolt is movably inserted into each of the two second mounting holes, and each second bolt is fitted with two second washers and threaded with a second nut to fix the moving tool processing box to the tooling body.

[0010] In a preferred embodiment, two internally threaded tapered pins are also fixedly connected to the moving tool processing box.

[0011] Compared with the prior art, the cylindrical welding fixture provided by this utility model has at least the following beneficial effects:

[0012] In this invention, the welding fixture ensures its machining accuracy through machining, the overfitting of pins, and post-weld processing.

[0018] Example

[0019] The existing cylindrical welding fixtures have the following drawbacks during use: during production, the need for employee skills and inspection to ensure small-batch production of single pieces greatly reduces production efficiency.

[0020] For this purpose, please refer to Figure 1 This utility model provides a cylindrical welding fixture, including: a fixture body 1, two positioning boxes 2 fixed to the inner wall of the fixture body 1 by a first fixing component, a moving tool processing box 4 fixed to the inner wall of the fixture body 1 by a second fixing component on one side of the two positioning boxes 2, two symmetrically distributed second fixing ear plates 5 fixed to the position near the moving tool processing box 4, and two symmetrically distributed first fixing ear plates 3 fixed to the fixture body 1 on one side of the two second fixing ear plates 5.

[0021] With existing technology, the welding of the cylinder relies on marking and standard plates for positioning and welding, with a production rate of 1 unit / 2 hours per shift; after adopting the new tooling, the production rate is 2.5 units / 1 hour, and the production efficiency is increased several times.

[0022] Further as Figure 1 As shown, it is worth noting that the cross-sections of both positioning boxes 2 and the moving tool processing box 4 are U-shaped.

[0023] Further as Figure 1 As shown, it is worth noting that the vertical cross-section of the first fixed ear plate 3 is larger than that of the second fixed ear plate 5.

[0024] Further as Figure 1 As shown, it is worth noting that the first fixing component includes a plurality of first mounting holes equidistantly arranged on the outer wall of the tooling body 1. A first bolt 7 is movably inserted into one of the first mounting holes, and the first bolt 7 cooperates with two first washers 6 and is threadedly connected to a first nut 8 to fix the positioning box 2 on the tooling body 1.

[0025] Further as Figure 1 As shown, it is worth noting that the second fixing component includes two second mounting holes on the outer wall of the tooling body 1. A second bolt 10 is movably inserted into each of the two second mounting holes, and each second bolt 10 is fitted with two second washers 9 and threaded with a second nut 11 to fix the moving tool processing box 4 to the tooling body 1. Two internally threaded tapered pins 12 are also fixed to the moving tool processing box 4. The pin holes that mate with the internally threaded tapered pins 12 are reamed holes. The pin shafts are machined with tapered grinding to ensure fitting accuracy.

[0026] In summary: First step: Place the two types of cylinders on the frame respectively, and use the first fixing ear plate 3 and the second fixing ear plate 5 to fix the rotating shaft to prevent displacement during the positioning and fixing process.

[0027] Step 2: Fix the mounting bases that need to be welded together to the cylinder using the two screws on the part positioning box 2 and the moving tool processing box 4, and spot weld them for positioning.

[0028] Step 3: Remove the screws on positioning box 2 and moving tool processing box 4, rotate the cylinder to perform welding, and the process will be completed.
