Description

Technical Field

[0001] This utility model relates to the field of auger shaft welding technology, and in particular to a positioning fixture for auger shaft welding. Background Technology

[0002] A screw conveyor shaft is typically a long shaft in cylindrical shape. The surface of the shaft has helical blades along the axial direction. The helical blades are wrapped around the shaft and are tightly connected to it. The helical blades can be fixed to the round shaft in various ways, with welding being a common method.

[0003] When welding the auger shaft using a welding device, the auger shaft needs to be positioned using a positioning fixture. First, place both ends of the auger shaft in a V-block or conical positioning sleeve. Then, according to the welding process requirements, adjust the position and angle of the blade positioning mechanism, place the blade in the corresponding position on the positioning plate, and support the spiral blade through a support structure.

[0004] Since the welding positioning fixture for auger shafts is usually designed and manufactured according to specific auger shaft dimensions and blade shapes, when the dimensions or blade shapes of the auger shaft change, the positioning fixture cannot be applied to other auger shafts, which means that the fixture may not be usable directly and different positioning fixtures are needed to position different auger shafts. Based on the above problems, this application proposes a positioning fixture for welding auger shafts. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a positioning fixture for welding auger shafts, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A positioning fixture for welding a auger shaft includes a mounting base, a mounting frame fixedly mounted on the top of the mounting base, an adjustment component inside the mounting frame, a through groove extending through the top of the mounting frame, an I-shaped slider slidably mounted inside the groove, a support wheel fixedly mounted on the top of the I-shaped slider, an auger shaft overlapping the surface of the support wheel, a distance detection component mounted on the side of the I-shaped slider near the edge of the mounting frame, a connecting frame fixedly mounted on the top of the mounting base, rectangular plates fixedly mounted on both the front and rear sides of the connecting frame, a hydraulic push rod mounted on the top of the rectangular plate via a hinge seat, a support plate mounted on the output end of the hydraulic push rod via a hinge seat, and a support component inside the connecting frame for facilitating support of the support plate.

[0008] Preferably, the adjustment assembly includes a rotating screw rotatably disposed inside the mounting bracket, a handle fixedly disposed at the rear end of the rotating screw, a threaded sleeve disposed on the surface of the rotating screw, a fixing plate fixedly disposed on the surface of the threaded sleeve, the fixing plate being fixedly mounted on the bottom end of the I-shaped slider, and a position locking element disposed on the surface of the rotating screw.

[0009] Preferably, the position locking component includes a locking wheel fixedly mounted on the surface of a rotating screw, a locking groove is formed on the surface of the locking wheel, a locking plate is overlapped inside the locking groove, a sliding plate is fixedly mounted on the top of the locking plate, a guide rod is fixedly mounted on the top of the sliding plate, a mounting shell is slidably mounted on the surface of the guide rod, the mounting shell is fixedly mounted on the rear side of the mounting frame, and a spring is connected between the upper sidewall of the mounting shell and the top of the sliding plate.

[0010] Preferably, the distance detection component includes a mounting block fixedly installed on the side of the I-shaped slider, an indicator needle fixedly provided on the side of the mounting block near the edge of the mounting frame, a scale plate overlapping the bottom of the indicator needle, and the scale plate fixedly installed on the top of the mounting frame.

[0011] Preferably, there are two support plates, and the two support plates are arranged in a V-shape, with the support plates in contact with the auger shaft.

[0012] Preferably, the support assembly includes a support shaft fixedly installed inside the connecting frame, and a rotating plate is rotatably disposed on the surface of the support shaft. The number of rotating plates is four, and the four rotating plates are respectively fixedly installed at the bottom of two support plates. A limiting sleeve for limiting the rotation plates is fixedly disposed on the surface of the support shaft.

[0013] Preferably, the locking groove is a V-shaped groove, the bottom of the locking plate has a V-shaped structure, and the locking plate is made of metal.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The positioning fixture for welding the auger shaft moves the I-beam slider through the adjustment component, which in turn moves the support wheel, so that the distance between the support wheel matches the radius of the auger shaft. The hydraulic push rod pushes the support plate through the hinge seat, causing the rotating plate to rotate on the surface of the support shaft, so that the support plate contacts the spiral blade. This allows the positioning fixture to be adjusted according to the shape of the blade according to the diameter of the auger shaft, thus making the positioning fixture applicable to auger shafts of different specifications, avoiding the inability of a single positioning fixture to position different auger shafts.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-7A positioning fixture for welding auger shafts includes a mounting base 1, a mounting frame 2 fixedly mounted on the top of the mounting base 1, an adjustment component inside the mounting frame 2, a through groove through the top of the mounting frame 2, an I-beam slider 7 slidably mounted inside the groove, a support wheel 8 fixedly mounted on the top of the I-beam slider 7, and an auger shaft overlapping the surface of the support wheel 8. The adjustment component includes a rotating screw 3 rotatably mounted inside the mounting frame 2, a handle 4 fixedly mounted at the rear end of the rotating screw 3, a threaded sleeve 5 threaded on the surface of the rotating screw 3, a fixing plate 6 fixedly mounted on the surface of the threaded sleeve 5, and a position locking element on the surface of the rotating screw 3. The rotating screw 3 is rotated by the handle 4, causing the threaded sleeve 5 to move the I-beam slider 7 via the fixing plate 6, which in turn moves the support wheel 8, thereby adjusting the position of the support wheel 8. This allows the support wheel 8 to provide positioning support for auger shafts of different specifications. A distance is provided on the side of the I-beam slider 7 near the edge of the mounting frame 2. The mounting base 1 has a connecting frame 19 fixedly installed on top of the detection component. Rectangular plates 20 are fixedly installed on both the front and rear sides of the connecting frame 19. A hydraulic push rod 21 is installed on the top of the rectangular plate 20 through a hinge seat. A support plate 22 is installed on the output end of the hydraulic push rod 21 through a hinge seat. There are two support plates 22, which are arranged in a V-shape. The support plates 22 are in contact with the auger shaft. The connecting frame 19 has a support assembly for supporting the support plates 22. The support assembly includes a support shaft 24 fixedly installed inside the connecting frame 19. Rotating plates 23 are rotatably installed on the surface of the support shaft 24. There are four rotating plates 23, which are fixedly installed on the bottom of two support plates 22 respectively. A limiting sleeve 25 is fixedly installed on the surface of the support shaft 24 to limit the rotation plates 23. The support plates 22 and the support shaft 24 can be connected through the rotating plates 23, so that the two support plates 22 are arranged in a V-shape, so that the support plates 22 can support different spiral blades.

[0025] Specifically, the position locking component includes a locking wheel 12 fixedly mounted on the surface of the rotating screw 3. A locking groove 13 is formed on the surface of the locking wheel 12, and a locking plate 14 is overlapped inside the locking groove 13. The locking groove 13 is a V-shaped groove, and the bottom of the locking plate 14 has a V-shaped structure. The locking plate 14 is made of metal, allowing the locking groove 13 to push the inclined surface of the locking plate 14, enabling the locking plate 14 to move upwards and out of the locking groove 13. A sliding plate 15 is fixedly mounted on the top of the locking plate 14, and a guide rod 16 is fixedly mounted on the top of the sliding plate 15. A mounting shell 17 is slidably mounted on the surface of the guide rod 16. The mounting shell 17 is fixedly mounted on the rear side of the mounting bracket 2. A spring 18 connects the upper sidewall of the mounting shell 17 and the top of the sliding plate 15. During rotation... During the rotation of screw 3, the screw 3 drives the locking wheel 12 to rotate, causing the inclined surface of the locking groove 13 to push the locking plate 14 upward. The locking plate 14 pushes the guide rod 16 upward through the sliding plate 15, and compresses the spring 18 through the sliding plate 15. When the distance between the support wheels 8 matches the radius of the auger shaft, the spring 18 pushes the sliding plate 15 downward through its rebound action, causing the sliding plate 15 to push the locking plate 14 into the locking groove 13. This locks the position of the locking wheel 12, and the locking wheel 12 locks the position of the screw 3, thus locking the position of the support wheel 8 after it has moved. This prevents the position of the support wheel 8 from changing during use, which would cause the support wheel 8 to fail to provide positioning support for the auger shaft.

[0026] Specifically, the distance detection component includes a mounting block 9 fixedly installed on the side of the I-beam slider 7. An indicator needle 10 is fixedly installed on the side of the mounting block 9 near the edge of the mounting frame 2. A scale plate 11 is attached to the bottom of the indicator needle 10. The scale plate 11 is fixedly installed on the top of the mounting frame 2. During the movement of the I-beam slider 7, the I-beam slider 7 drives the indicator needle 10 to move through the mounting block 9. The distance moved by the indicator needle 10 is measured by the scale plate 11. Since the side of the indicator needle 10 away from the I-beam slider 7 is on the same vertical projection plane as the facing surface of the support wheel 8, the distance moved by the indicator needle 10 is the distance moved by the support wheel 8. This allows the movement distance of the support wheel 8 to be measured, making the support wheel 8 more compatible with the round shaft of the auger shaft.

[0027] The auger shaft welding positioning fixture is connected to a 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0028] In use: According to the specifications of the auger shaft, turn the handle 4 to drive the rotating screw 3 to rotate, so that the handle 4 drives the screw sleeve 5 to move, so that the two screw sleeves 5 move closer or further apart. The screw sleeve 5 drives the I-beam slider 7 to slide inside the groove, and the I-beam slider 7 drives the support wheel 8 to move. When the distance between the support wheels 8 meets the radius of the auger shaft, the hydraulic push rod 21 drives the output end to extend, so that the hydraulic push rod 21 pushes the support plate 22 to flip through the hinge seat. The support plate 22 drives the rotating plate 23 to rotate on the surface of the support shaft 24, so that the support plate 22 contacts the auger shaft, thereby positioning the auger shaft. Then, the auger shaft is welded by an external welding device.
