Description

Technical Field

[0001] The utility model relates to the field of spiral blades, and more specifically, to a supporting frame of a spiral blade welding and fixing device. Background Art

[0002] The spiral blade is an important component used in conveying equipment. It converts the rotational power of the spiral shaft into the propulsion force of the material. In industrial applications, the combination of the spiral blade and the spiral shaft is a key structure for realizing material conveying, stirring and mixing.

[0003] At present, when most factories weld the spiral blades to the spiral shaft, they generally fix one end of the spiral shaft by a fixing device first, and then put the spiral blade on the unfixed end. In order to improve efficiency, this end is generally not fixed, and the workers start welding operations. This will cause the spiral shaft to be unstable and easy to shake, resulting in poor welding processing accuracy of the spiral blades. However, when fixing one end of the spiral blade on the spiral shaft, it is necessary to push another fixing device supported by a support frame to fix it after the threaded blade is put on the spiral shaft (the support frame is heavy for stable support, so it is more labor-intensive to push), which is more troublesome to operate and seriously affects the welding efficiency.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a support frame for a spiral blade welding fixing device. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a support frame for a spiral blade welding and fixing device.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a support frame for a spiral blade welding fixing device, comprising a base, one side of the base is slidably connected to an expansion seat, support plates for installing the fixing device are installed on the top of the base and the expansion seat, and the support plate on the top of the expansion seat can move laterally, and a limiting assembly is also provided between the support plate and the expansion seat, which is used to limit the support plate on the expansion seat at an appropriate position.

[0007] Preferably, a groove is provided at the side end of the base, and a horizontal plate with the same internal cross-section as the groove is movably connected inside the groove. The side of the horizontal plate extending from the groove is fixed to the expansion seat, and universal wheels with locking function are installed on both sides of the bottom of the expansion seat.

[0008] Preferably, a guide rail A for sliding the slider A is fixedly connected to the top of the expansion seat, and a support plate on the expansion seat is fixed to the top of the slider A.

[0009] Preferably, the limiting assembly includes an upper opening slot seat welded on the support plate, guide rails B for sliding sliders B are fixedly connected to the two sides of the upper opening slot seat, a lifting plate is fixedly connected between the sliders B, a spring is installed between the bottom end of the lifting plate and the inner bottom wall of the upper opening slot seat, a T-shaped plate is welded to the top end, limiting blocks are provided on both sides of the T-shaped plate, vertical plates are provided on both sides of the expansion seat, and through grooves with a height lower than the limiting block are opened on both sides of the vertical plate to limit the position after the limiting block passes through.

[0010] Preferably, a slope is provided on one side of the limiting block and one side of the inner surface of the through slot, and a downward pressure force can be generated on the limiting block through the action of the slopes on the limiting block and the through slot, thereby ensuring that it can pass through the through slot smoothly.

[0011] Preferably, a handle A is welded on the surface of the support plate on the expansion seat for facilitating its movement, and a handle B is fixedly connected to the upper part of the surface of the T-shaped plate for facilitating its downward pressing, so as to facilitate the pushing and pressing operations by the staff.

[0012] Preferably, a connecting plate A with a through hole provided inside is fixedly connected to the top of the base on the side opposite to the upper support plate, a connecting plate B is welded to the top of the expansion seat on the side close to the base, and a screw capable of passing through the through hole is fixedly connected to the surface of the connecting plate B, and a nut is threadedly connected to the outer wall of the screw to prevent the expansion seat from moving back and forth during transportation and affecting transportation.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The present invention first fixes one end of the spiral shaft through the fixing device on the base, and after the fixing is completed, the support plate on the expansion seat is pushed to move horizontally, so that it moves to a position that is not flush with the support plate on the base, so that the threaded blade is sleeved on the threaded shaft, and then the support plate is dragged to reset. After the support plate moves to the above two positions, it can be fixed by the limit assembly, and then the other end of the threaded shaft can be fixed by the fixing device on the support plate, and then the spiral blade can be installed. In this way, both sides of the spiral shaft can be fixed, making the installation of the threaded blade more accurate, and the fixing operation is simple. The fixing device on one side can be pushed like a sliding door to achieve the purpose of sleeve the threaded blade on the spiral shaft, and the staff does not need to move the entire support frame and the fixing device, thereby solving the problem that when fixing one end of the spiral blade on the spiral shaft sleeve in the background technology, it is also necessary to push another fixing device supported by the support frame to fix it after the threaded blade is sleeved on the spiral shaft, which is more troublesome to operate and seriously affects the welding efficiency.

The utility model can push the expansion seat to move back and forth in a straight line along the horizontal direction of the base to adjust the distance between the base and the expansion seat, thereby adjusting the distance between the two support plates. Fixing devices are installed on the two support plates, so as to facilitate the adjustment of the distance between the two support plates according to different lengths of the spiral shaft;

[0016] 3. The utility model can generate a downward pressure on the limiting block through the action of the limiting block and the slope on the through slot, thereby ensuring that it can pass through the through slot smoothly, without the need for workers to perform downward pressure operation, which is more convenient;

[0017] 4. The utility model can push the expansion seat to move toward the base so that the screw on the connecting plate B can pass through the through hole on the connecting plate A. After the insertion is completed, turn the nut clockwise to install the nut on the screw, and the nut slowly presses against the surface of the connecting plate A, thereby achieving the fixation between the connecting plate A and the connecting plate B, and also fixing the base and the expansion seat to prevent the expansion seat from moving back and forth during transportation and affecting the transportation.

[0026] like Figure 1-4 As shown, the utility model provides a support frame for a spiral blade welding fixing device, including a base 1, one side of the base 1 is slidably connected to an expansion seat 2, a support plate 3 for installing the fixing device is installed on the top of the base 1 and the expansion seat 2, and the support plate 3 on the top of the expansion seat 2 can move laterally, and a limiting component 5 is also provided between the support plate 3 and the expansion seat 2, which is used to limit the support plate 3 on the expansion seat 2 at a suitable position.

[0027] Two fixing devices can be installed on one support frame of the utility model. When in use, the expansion seat 2 can be pushed to move back and forth in a straight line along the horizontal direction of the base 1 to adjust the distance between the base 1 and the expansion seat 2, thereby adjusting the distance between the two support plates 3. Fixing devices are installed on the two support plates 3, so that it is convenient to adjust the distance between the two support plates 3 according to different spiral shaft lengths. First, one end of the spiral shaft is fixed by the fixing device on the base 1 (in addition to the fixing device, a rotating component can also be installed on the support plate 3 to rotate the threaded shaft, so as to facilitate the staff to weld the threaded blades). After the fixing is completed, the support plate 3 on the expansion seat 2 is pushed to move horizontally, so as to move to a position that is not in contact with the support plate 3 on the base 1 The screw shaft 3 is fixed to the horizontal position by the fixing device 5 on the support plate 3. The fixing device 5 can be used to fix the screw shaft 3. The fixing device 5 can be used to fix the screw shaft 3. The fixing device 5 can be used to fix the screw shaft 3. The fixing device 5 can be used to fix the screw shaft 3.

[0028] A groove 6 is provided at the side end of the base 1, and a transverse plate 7 having the same cross section as that of the groove 6 is movably connected inside the groove 6 (since the cross sections of the two are the same, the transverse plate 7 can only move linearly along the inside of the groove 6 to maintain the relative linear movement between the base 1 and the expansion seat 2). The side of the transverse plate 7 extending from the groove 6 is fixed to the expansion seat 2, and wheels 8 with locking function are installed on both sides of the bottom of the expansion seat 2. The top of the expansion seat 2 is fixedly connected to a guide rail A9 for sliding the slider A10. The support plate 3 on the expansion seat 2 is fixed to the top of the slider A10. The limiting assembly 5 includes an upper opening groove seat 51 welded on the support plate 3. Guide rails B52 for the slider B53 to slide are fixedly connected on both sides inside, and a lifting plate 510 is fixedly connected between the sliders B53. A spring 54 is installed between the bottom end of the lifting plate 510 and the inner bottom wall of the upper opening groove seat 51, and a T-shaped plate 55 is welded on the top. Limiting blocks 56 are provided on both sides of the T-shaped plate 55, and vertical plates 57 are provided on both sides of the expansion seat 2. Through grooves 58 with a height lower than that of the limiting block 56 are opened on both sides of the vertical plate 57 to limit the position after the limiting block 56 passes through. A handle A4 is welded on the surface of the support plate 3 on the expansion seat 2 to facilitate pushing its movement, and a handle B11 is fixedly connected to the upper part of the surface of the T-shaped plate 55 to facilitate pressing it down.

[0029] Push the expansion seat 2 to move back and forth, the expansion seat 2 drives the cross plate 7 to move back and forth, and the cross plate 7 moves back and forth in a straight line along the inside of the groove 6 to maintain the linear movement of the expansion seat 2 relative to the base 1. When it moves to the appropriate position, lock the wheel 8. In this way, since the base 1 and the expansion seat 2 have a certain weight and will not move easily, the relative distance between the two support plates 3 can be fixed, so that it is convenient to adjust the distance between the two support plates 3 on the support frame according to the length of the threaded shaft installed with the spiral blade.

[0030] Furthermore, a connecting plate A12 with a through hole 13 is fixedly connected to the top of the base 1 on the side opposite to the upper support plate 3, a connecting plate B14 is welded to the top of the expansion seat 2 on the side close to the base 1, and a screw 15 capable of passing through the through hole 13 is fixedly connected to the surface of the connecting plate B14, and a nut is threadedly connected to the outer wall of the screw 15. When the support frame needs to be transported, the expansion seat 2 can be pushed toward the base 1 to pass the screw 15 on the connecting plate B14 through the through hole 13 on the connecting plate A12. After the insertion is completed, the nut is installed on the screw 15 by turning it clockwise, and the nut slowly presses against the surface of the connecting plate A12, thereby achieving fixation between the connecting plate A12 and the connecting plate B14, and also fixing the base 1 and the expansion seat 2 to prevent the expansion seat 2 from moving back and forth during transportation and affecting the transportation.

[0031] The staff first pulls the T-shaped plate 55 downward through the handle B11, and the T-shaped plate 55 drives the lifting plate 510 to move downward, and the lifting plate 510 drives the spring 54 to contract downward, and the lifting plate 510 drives the slider B53 to move downward, and the slider B53 moves linearly downward along the guide rail B52 to maintain the linear movement of the lifting plate 510 relative to the upper opening groove seat 51, so as to align the limiting block 56 with the through groove 58 on the vertical plate 57, and the handle A4 can be used to push the support plate 3 on the expansion seat 2 to move back and forth, and the support plate 3 drives the slider A10 to move, and the slider A10 slides along the guide rail A9. When the support plate 3 on the expansion seat 2 is aligned with the support plate 3 on the base 1, the T-shaped The limiting block 56 on one side of the plate 55 passes through the through slot 58 on the vertical plate 57 on one side of the expansion seat 2. When the support plate 3 on the expansion seat 2 and the support plate 3 on the base 1 are in a staggered state, the limiting block 56 on the other side of the T-shaped plate 55 passes through the through slot 58 on the vertical plate 57 on the other side of the expansion seat 2. At these times, it is only necessary to loosen the handle B11 so that the spring 54 can use its elasticity to drive the T-shaped plate 55 and the limiting block 56 to move upward for reset. The limiting block 56 can be pressed against the vertical plate 57 to fix the position of the support plate 3. Conversely, the T-shaped plate 55 can be pressed down again to slide the support plate 3 again. This is the same pushing method as pushing a door, which is relatively simple to operate and easy for staff to operate.

[0032] like Figure 1 and Figure 4 As shown, the utility model provides a slope 59 on one side of the limiting block 56 and one side of the inner surface of the through slot 58, so that when the inclined block passes through the through slot 58 for fixation, the limiting block 56 can be pressed downward by the action of the slope, thereby ensuring that it can pass through the through slot 58 smoothly, without the need for staff to perform a downward pressure operation, which is more convenient. The reason why the slope 59 is not provided on the other side is to prevent the slope 59 from affecting the stable fixation of the limiting block 56 and the vertical plate 57 to the support plate 3.

[0033] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
