Detailed ways

The technical scheme of the utility model is described in detail below in conjunction with the drawings.

Please refer to Figures 1 to 3, the alignment and positioning device of this embodiment includes a workpiece support column 1, the outer wall of the workpiece support column 1 near the upper end is provided with several evenly distributed triangular positioning blocks 2, and the triangular positioning blocks 2 face The upper side is an inclined surface 21 , the surface of which is flat and smooth, and an upwardly protruding baffle 3 is provided at the end of the inclined surface 21 .

In this embodiment, when the lower end of the workpiece is slid to the end of the triangular positioning block 2 along the slope 21 of the triangular positioning block 2, the baffle plate 3 at the end of the triangular positioning block 2 can limit the workpiece to continue to move to the left, and then, When the workpiece is processed, even if the upper end surface of the workpiece produces a downwardly applied force, making the lower end of the workpiece easily slide to the left with the inclined surface 21, but at this time, because of the existence of the baffle plate 3, the workpiece still cannot Move to the left along with the gravity, and at the same time, due to the existence of the triangular positioning block 2, the lower end pin of the workpiece can always lean against the slope 21 of the triangular positioning block 2, thereby ensuring that the workpiece is always on a plane, and the workpiece's The edge position will not be uneven due to uneven force, thereby realizing the alignment and positioning of the workpiece.

Preferably, the slope 21 is provided with several openings 211 evenly arranged up and down and positioning pins 212 movably inserted in the openings 211 .

In this embodiment, when different types of products are processed, the lengths of the legs at the lower end of the workpiece are different. When the length of the legs at the lower end of the workpiece is not enough to allow it to slide to the end of the inclined plane 21, the positioning pin 212 can be used to carry out the work on the workpiece. Further limit, that is, when the legs at the lower end of the workpiece slide along the slope 21 until the lower end surface of the workpiece fits with the upper end surface of the workpiece support column 1, the positioning pin 212 is inserted into the opening 211, so that the positioning pin 212 abuts against the legs at the lower end of the workpiece to form a consistent effect with the baffle plate 3, so that the aligning and positioning device of the present application can be applied to more workpieces with different lengths of legs at the lower end.

Preferably, the workpiece support column 1 is an annular cylindrical structure, and the inner wall of the workpiece support column 1 near the upper end is provided with an electromagnet 11 that is attracted to the workpiece.

In this embodiment, the wire can be penetrated from the bottom of the workpiece support column 1, so as to energize the electromagnet 11 on the inner wall of the workpiece support column 1, and when the workpiece support column 1 is energized, the electromagnet 11 can be The workpiece arranged at its upper end is attracted, so that the workpiece can be fixed on the workpiece support column 1, and if the workpiece has been processed, only a break point is needed to realize the disassembly of the workpiece.

In this embodiment, the hollow design of the workpiece support column 1 of the present application can reduce the manufacturing cost of the workpiece support column 1 while reducing the weight of the workpiece support column 1, and the cylindrical structure, compared with the prismatic structure, can be more convenient. The shape of the workpiece is fixed above it.

Preferably, at least three triangular positioning blocks 2 are arranged on the outer wall near the upper end of the workpiece support column 1 .

Preferably, the shape of the triangular positioning block 2 is a right triangle.

Preferably, the triangular surface of the triangular positioning block 2 and the workpiece supporting column 1 is in an arc-shaped structure.

In this embodiment, when the side of the triangular positioning block 2 and the workpiece support column 1 is an arc-shaped structure, the triangular positioning block 2 can perfectly fit the cylindrical workpiece support column 1, and if the triangular positioning block 2 The side where the positioning block 2 is fitted and connected with the workpiece support column 1 is a straight-edge row structure, so there will always be a part of the triangular positioning block 2 that cannot be fitted and connected with the triangular positioning block 2, and it is easy to cause the triangular positioning block 2 to be improperly fixed. The phenomenon, which in turn affects the machining accuracy.

In this embodiment, the workpiece support column 1 and the triangular positioning block 2 may be an integral structure welded by metal materials.

It can be seen that the implementation of the aligning and positioning device described in FIGS. 1 to 3 can solve the situation that the workpiece is displaced during the machining process, so as to improve the production efficiency and increase the machining accuracy of the workpiece.

In addition, implementing the aligning and positioning device described in FIGS. 1 to 3 can complete the fixing process of the workpiece without using clamping tools such as V-shaped pliers, and the operation is simple and the efficiency is improved.
