Description

Clamping and positioning structure

This creation provides a technical field of clamps, especially a clamping and positioning structure technically provided. Several rectangular opening keyways are arranged on the top cover according to specific angles or right angles, which can absorb the tolerance of the center size and can be used. It is convenient to locate the processor at a specific angle or at right angles.

Press, as shown in Figure 1, clamping is a necessary process for processing machinery. However, following the progress of the times, the action of clamping has also changed. Figure 1 reveals a known clamping and positioning device 10, and the clamping One side of the fixture plate or workpiece 20 is provided with a positioning pull bolt 21 in the center of the bottom surface of the fixture plate or workpiece 20, and one or two positioning pins 22 are provided on the side of the bottom surface, and the angle between the two positioning pins 22 to the center is The angle of 90 degrees, and the conventional clamping and positioning device 10 is provided with a lining tube 11 corresponding to the positioning pull bolt 21, and a plurality of steel balls 12 are arranged in the lining tube 11 to buckle the concave arc groove 211 on the positioning pull bolt 21 Form fast positioning or release, and one or two positioning pins 22 are provided with two circular concave holes 13 with an included angle of 90 degrees, and the circular concave holes 13 can be inserted and positioned by positioning pins 22 .

But, its known clamping and positioning device 10 has only two circular recessed holes 13, so its scope of use has its limitation, and its circular recessed hole 13 does not have lateral opening again. The part of the mouth can only be drilled first and then milled, and the precision is not easy to control, and it is not easy to process. Those with side openings can be milled directly, the precision is better controlled, and relatively easy to process. On the other hand, the form of the circular concave hole 13 should be very precise in size to the center, otherwise the positioning pin 22 cannot be inserted into the positioning and it will be a missing person.

Therefore, in view of the problems existing in the above-mentioned conventional structures, how to develop a more ideal and practical innovative structure is what consumers are eagerly looking forward to, and it is also the goal and direction that related businesses must work hard to develop breakthroughs.

In view of this, the author has been engaged in the manufacturing, development and design of related products for many years. After careful design and careful evaluation for the above-mentioned goals, he finally obtained a truly practical creation.

The main purpose of this creation is to provide a clamping and positioning structure. Several rectangular opening keyways can be equally divided according to specific angles or right angles on the top cover, which can absorb the dimensional tolerances of the center and facilitate the positioning of processors at specific angles or right angles. .

In order to achieve the above purpose, this creation provides a clamping and positioning structure, which includes: a clamp base, an inner liner and an outer sleeve are arranged on the clamp base, and a top cover is arranged on the outer sleeve to It consists of a clamping and positioning device. The clamping and positioning device is equipped with a number of steel balls for positioning at the inner liner; the main point is that several rectangular openings can be equally divided on the top cover according to a specific angle or a right angle. Keyways with rectangular open keyways absorbing to center dimensional tolerances, several rectangular open keyways for specific angles or right angles Bit processing, the positioning pin can prevent the workpiece from rotating, and the rectangular opening keyway has chamfers to facilitate the placement of the positioning pin.

Regarding the techniques, means and effects used in this creation, hereby cite a preferred embodiment and describe it in detail with the drawings. I believe that the above-mentioned purpose, structure and characteristics of this creation should be able to gain a deep and specific understanding. .

This creation provides a designer of a clamping and positioning structure.

In order to enable your review committee to have a better understanding and understanding of the purpose, characteristics and functions of this creation, the implementation methods and drawings are described in detail as follows:

As shown in Figures 2 to 5, this creation provides a clamping and positioning structure, which includes:

A clamp base 31, an inner liner 32 and an outer sleeve 33 are assembled on the aforementioned clamp base 31, and a top cover is assembled on the aforementioned outer sleeve 33 34, to form a clamping and positioning device 30, the aforementioned clamping and positioning device 30 is provided with a number of steel balls 35 for positioning at the aforementioned lining pipe 32; it is characterized in that:

Several rectangular opening key grooves 341 can be equally divided according to a specific angle or a right angle on the aforementioned top cover portion 34, and the aforementioned rectangular opening key grooves 341 can be absorbed to the center dimensional tolerance, and several aforementioned rectangular opening key grooves 341 can facilitate Machining at specific angles or at right angles.

In the clamping and positioning structure, the aforementioned clamping and positioning device 30 can be used for quickly clamping a jig plate or workpiece 40 , and one or two positioning pins 41 are provided on the bottom surface of the aforementioned jig plate or workpiece 40 .
