Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of condenser processing, in particular to a fixture. Background Art
[0002] A condenser is composed of a condenser tube bent multiple times and reinforcing bars welded to the condenser tube. In order to ensure the strengthening and fixing effect of the welded reinforcing bars, the distance between the reinforcing bars usually needs to be equal. During welding, the operator adsorbs the reinforcing bars through a magnetic plate with magnetism and then transfers them. However, during the transfer, due to reasons such as shaking or collision, the problem of the inclination of the reinforcing bars often occurs, which will affect the welding effect of the reinforcing bars. Summary of the Utility Model
[0003] The utility model provides a fixture to solve the above-mentioned deficiencies of the prior art. When transferring the reinforcing bars, it can stably limit the reinforcing bars to prevent problems such as the movement of the reinforcing bars, and has strong practicability.
[0004] In order to achieve the purpose of the utility model, the following technology is proposed:
[0005] A fixture includes a middle plate. A pair of upward extension plates are arranged on the long side of the middle plate. A pair of guide grooves are formed in the middle plate along its width direction. A limiting plate is arranged at the upper end of the guide groove. A moving hole is formed in the limiting plate. A pair of movable rods are movably arranged in the guide groove. The movable rods pass through the moving hole. The limiting plate plays a role in limiting the lower disc at the lower end of the movable rod, thus facilitating the movement operation of the inner top block. An active end plate is installed at the upper end of the movable rods at the same end. A moving concave part is installed on the active end plate. An inclined hole is formed in the moving concave part. The upper end of the inclined hole extends inwardly and obliquely. An inner push rod is movably arranged in the inclined hole. A moving cross plate is arranged between the inner push rods on the same side. A connecting rod is arranged on the moving cross plate. A pair of concave lifting handles are installed on the middle plate. A vertical hole is formed in the vertical section of the concave lifting handle. The connecting rod passes through the vertical hole. An upper pulling cross plate is arranged at the inner side end of the connecting rod. A pair of guiding vertical rods are arranged on the upper pulling cross plate. The guiding vertical rods pass through the horizontal section of the concave lifting handle. A rotating end plate is installed on the active end plate. A moving lead screw is rotatably arranged on the rotating end plate. A rotating cap is arranged at the outer side end of the moving lead screw. An inner moving plate is arranged at the outer side end of the moving lead screws on the same side. An inner top block is arranged at the lower end of the inner moving plate. The arrangement of the moving lead screw can adjust the distance between the inner top blocks, which is convenient for fixing when transferring reinforcing bars of different lengths. During the transfer, the operator shortens the distance between the concave lifting handle and the upper pulling cross plate. The middle plate is a moving part. When it moves, it will act on the inclined hole through the inner push rod, and then make the moving concave parts approach each other. During the approaching process, the reinforcing bars can be limited by the inner top blocks.
[0006] Further, a plurality of U-shaped bayonets are formed on the lower wall of the middle plate to limit the reinforcing rods, so as to ensure that the intervals between the reinforcing rods are equal and to avoid problems such as tilting of the reinforcing rods.
[0007] Further, a spring is sleeved on the lower end of the guiding vertical rod, and the spring is located below the concave handle. When the clamping is cancelled, the spring can move the upper pulling cross plate downward, thus facilitating the cancellation of the positioning operation of the reinforcing rod.
[0008] Further, a plurality of positioning round holes are formed in the inner wall of the inner top block, and the positioning round holes play a role in positioning the reinforcing rods.
[0009] The advantages of the above technical solutions are as follows:
[0010] The utility model is convenient for transferring the reinforcing rods, and can ensure the attitude and neatness of the reinforcing rods during the transfer. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings.
[0012] Figure 1 The three-dimensional structure diagram of one of the embodiments is shown.
[0013] Figure 2 The enlarged view of part A is shown. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0014] As Figures 1 - 2 shown, a fixture includes a middle plate 1, and a plurality of U-shaped bayonets 10 are formed on the lower wall of the middle plate 1. A pair of upward extension plates 11 are provided on the long sides of the middle plate 1. A pair of guiding grooves 12 are formed in the middle plate 1 along its width direction. A limiting plate 13 is provided at the upper end of the guiding groove 12, and a moving hole is formed in the limiting plate 13. A pair of movable rods 2 are movably arranged in the guiding groove 12. The movable rods 2 pass through the moving hole. At the upper ends of the movable rods 2 at the same end, movable end plates 20 are installed. A moving concave member 21 is installed on the movable end plate 20. An inclined hole 22 is formed in the moving concave member 21. The upper end of the inclined hole 22 extends obliquely inward. An inner push rod 23 is movably arranged in the inclined hole 22. A moving cross plate 24 is provided between the inner push rods 23 on the same side. A connecting rod 3 is provided on the moving cross plate 24. A pair of concave handles 32 are installed on the middle plate 1. A vertical hole 30 is formed in the vertical section of the concave handle 32. The connecting rod 3 passes through the vertical hole 30. The inner end of the connecting rod 3 is provided with an upper pulling cross plate 33. A pair of guiding vertical rods 34 are provided on the upper pulling cross plate 33. The guiding vertical rods 34 pass through the horizontal section of the concave handle 32. A spring is sleeved on the lower end of the guiding vertical rod 34, and the spring is located below the concave handle 32.
[0015] A rotating end plate 15 is installed on the movable end plate 20. A moving lead screw 26 is rotatably provided on the rotating end plate 15. A rotating cap 27 is provided at the outer end of the moving lead screw 26. An inner moving plate 28 is provided at the outer end of the moving lead screw 26 on the same side. An inner top block 29 is provided at the lower end of the inner moving plate 28. A plurality of positioning round holes are formed in the inner wall of the inner top block 29.
[0016] During the operation of this embodiment, the operator transfers the fixture above the previously neatly arranged reinforcing bars. And before the transfer, according to the length of the reinforcing bars, the position of the inner top block 29 can be adjusted by rotating the moving lead screw 26.
[0017] Then the operator moves the fixture downward. And when moving, it is necessary to ensure that the reinforcing bars are aligned with each U-shaped bayonet 10. When moving downward, the positioning round holes on the inner top block 29 should be located at both ends of the reinforcing bars.
[0018] Then when the middle plate 1 moves the upper pull cross plate 33 upward, it can act on the inclined holes 22 through the inner push rod 23, thereby making the moving concave parts 21 approach each other. And when the moving concave parts 21 approach each other, it will pull the inner top block 29 to move inward, and limit both ends of the reinforcing bar through the inner top block 29. After the limiting is completed, transfer the reinforcing bar, and place the reinforcing bar on the condenser tube and perform spot welding.
[0019] After spot welding, cancel the upward pulling action on the upper pull cross plate 33, then cancel the clamping of the reinforcing bar, and then perform full welding operation.
