DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0022] Embodiment 1: A portable positioning device, see Figure 1 and Figure 2 As shown, it includes a base 1, a centering sleeve 2, a positioning pin 4 and a handle 5. The centering sleeve 2 is fixed to the base 1 by welding. Two countersunk holes 101 are provided on both sides of the base 1. The four countersunk holes 101 are distributed in a rectangular shape on both sides of the base 1. By passing the bolts through the countersunk holes 101 and tightening them on the processing table, the base 1 is conveniently fixed on the processing table. A positioning pin 4 for positioning parts is horizontally slidably arranged in the centering sleeve 2. A handle 5 is threadedly arranged at the rear end of the positioning pin 4. It also includes a limiting bolt 3 and a spring 6. The limiting bolt 3 is threadedly arranged on the centering sleeve 2. A limiting groove 401 is arranged on the positioning pin 4. The limiting bolt 3 cooperates with the limiting groove 401. A spring 6 is wound around the positioning pin 4. The spring 6 is located in the centering sleeve 2. The spring 6 is used to push the positioning pin 4 to slide and reset to fix the parts.

[0023] When it is necessary to position the part, first pull the handle 5 to drive the positioning pin 4 to slide backward along the centering sleeve 2. At this time, the spring 6 is compressed and deformed by the force, so that the limiting groove 401 is aligned with the limiting bolt 3. Then, by rotating the limiting bolt 3, the limiting bolt 3 is penetrated into the centering sleeve 2 and stuck in the limiting groove 401 of the positioning pin 4. At this time, the positioning pin 4 cannot move after the handle 5 is loosened. Subsequently, the part is placed in front of the positioning pin 4, and the limiting bolt 3 is rotated in the opposite direction to disengage the limiting bolt 3 from the limiting groove 401. At this time, the spring 6 loses the force and returns to its original state, thereby pushing the positioning pin 4 to slide and reset, so that the positioning pin 4 positions and blocks the part. After the handle 5 hits the centering sleeve 2, the positioning pin 4 stops, thereby achieving the purpose of positioning the part.

[0024] Example 2: Based on Example 1, refer to Figure 3 As shown, it also includes a docking plate 7 installed at the lower rear side of the base 1 by welding, and a plurality of card slots 701 are opened on the docking plate 7. The bottom rear end of the handle 5 is fixedly connected to a guide block 8 by welding. A card block 9 is longitudinally slidably arranged on the guide block 8, and the card block 9 is engaged with the card slot 701. A card plate 11 is fixedly connected to the guide block 8 by welding, and a rotating rod 10 is rotatably arranged on the top of the card block 9, and the rotating rod 10 is engaged with the card plate 11.

[0025] When the handle 5 drives the positioning pin 4 to slide along the centering sleeve 2, the handle 5 drives the guide block 8 to move at the same time. At this time, the guide block 8 drives the clamping block 9 to move synchronously. When the handle 5 needs to be fixed, the clamping block 9 is slid downward along the guide block 8 so that the clamping block 9 is inserted into the clamping groove 701, so that the handle 5 is limited, thereby strengthening the fixation and limitation of the positioning pin 4; the clamping block 9 is pulled to slide upward along the guide block 8 so that the clamping block 9 is disengaged from the clamping groove 701, and at the same time, the clamping block 9 drives the rotating rod 10 to insert the clamping plate 11, and the rotating rod 10 is rotated 90 degrees so that the rotating rod 10 and the clamping plate 11 are clamped and limited, thereby preventing the clamping block 9 from affecting the movement of the guide block 8 and the handle 5.

[0026] See also Figure 4 As shown, it also includes a scale plate 13 fixedly connected to the side of the docking plate 7 by bolt connection, a slide groove 14 is provided on the scale plate 13, an indicating block 12 for indicating the scale mark on the scale plate 13 is slidably arranged in the slide groove 14, and the indicating block 12 is fixedly connected to the guide block 8 by welding.

[0027] When the guide block 8 moves with the handle 5, the guide block 8 drives the indicator block 12 to slide along the slide groove 14. At this time, the scale of the scale plate 13 indicated by the indicator block 12 changes. The distance moved by the positioning pin 4 can be calculated based on the scale change of the scale plate 13 indicated by the indicator block 12.

[0028] See also Figure 1 and Figure 4 As shown, a wiping block 15 is horizontally slidably arranged on the scale plate 13; a protective sleeve 16 is sleeved on the front end of the positioning pin 4; and an anti-slip pattern 17 is arranged on the limiting bolt 3.

[0029] When the scale mark on the scale plate 13 is blocked by stains, the wiping block 15 is pulled to slide along the scale plate 13 so that the wiping block 15 can wipe off the stains on the scale plate 13; the protective cover 16 can prevent the positioning pin 4 from scratching the surface of the part when positioning the part, making the positioning pin 4 more gentle when contacting the part; the anti-slip pattern 17 can prevent the staff from slipping when turning the limit bolt 3.
