Description

Technical Field

[0001] The utility model relates to the technical field of positioning mechanisms, in particular to a positioning mechanism for a steel bar straightening machine. Background Art

[0002] In the early days, the positioning mechanism of the base of the rebar straightening machine was relatively simple. Usually it was a simple bracket or base platform used to fix the rebar straightening machine to the ground; the design of these bases was not particularly complicated, and they mainly played the role of fixing and supporting; with the development of rebar straightening machine technology, the base positioning mechanism began to adopt a bolt fixing mechanism; the bolt fixing mechanism achieves stable position fixation by installing the rebar straightening machine on the bolt holes on the ground or base. This mechanism design can provide reliable fixation to ensure that the rebar straightening machine will not move or shake during operation;

[0003] Most positioning mechanisms with wheel seats will cause vibrations during operation, which will indirectly affect the base, causing it to vibrate and then move, causing an impact. It is common to put a pad under the base to reduce the displacement caused by the vibration of the base, but this requires putting a pad every time the machine is working, which is very troublesome. Therefore, the above problems need to be improved. Utility Model Content

The lifting assembly includes a threaded column 7 vertically fixed to the top surface of the storage groove, a threaded tube sleeved on the threaded column 7, a driven bevel gear 6 fixedly sleeved on the outer wall of the threaded tube, and a fixed block fixed to the front end of the top surface of the wheel seat 2. The height of the wheel seat 2 can be adjusted by rotating the driven bevel gear 6, and the threaded column 7 facilitates the guidance and movement of the driven bevel gear 6; the inner side surface of the fixed block is rotatably connected to the rotating shaft through a bearing 8, and the inner end of the rotating shaft is fixedly connected to the active bevel gear 5, and the driven bevel gear 6 is driven by the rotation of the active gear 5; the two driven bevel gears 6 are meshed with the active bevel gear 5 for transmission.

[0020] In the utility model, a hand wheel 3 is fixedly connected to the outer end of the rotating shaft, and the height of the wheel seat 2, that is, the height of the moving wheel 4, can be adjusted by rotating the hand wheel 3. A plug-in hole connected to the storage groove is provided on the inner side surface of the base 1, and a wedge block 9 is provided inside the plug-in hole, and the wheel seat 2 can be clamped on the base 1 through the wedge block 9; a plug-in groove cooperating with the wedge block 9 is longitudinally provided on the inner side surface of the wheel seat 2, and the inner end of the wedge block 9 is movably plugged into the plug-in groove of the wheel seat 2.

Then, the internal threaded tube on the inner side of the driven bevel gear 6 cooperates with the external thread of the threaded column 7, and the wheel seat 2 is adjusted downward as a whole to expose the moving wheel 4. When it is adjusted to a certain height, the wedge block 9 movably connected to the base 1 is pushed into the hole on the inner side of the wheel seat 2 to clamp the wheel seat 2 on the base 1. When the machine is to be fixed, the wedge block 9 stuck in the wheel seat 2 is first pulled out, and the hand wheel 3 is turned clockwise to drive the active gear 5 and then the driven bevel gear 6. Then, the internal threaded tube on the inner side of the driven bevel gear 6 cooperates with the external thread of the threaded column 7 to adjust the wheel seat 2 as a whole until the moving wheel 4 is adjusted into the base 1, so that the base 1 can be stably placed on the ground, thereby playing the role of fixing the steel bar straightening machine.
