Description

Object positioning device

The invention relates to the fixing of an object; in particular to an object positioning device which has a fast installation and a reliable positioning.

In some applications where a shaft is used as the connection, the stability of the components after installation has a certain degree of influence on the stability of the operation of the mechanism, and the installation method is related to the work efficiency. Taking an automated chain magazine as an example, the chain uses a plurality of shafts to pass through two adjacent chain blocks one by one, so that most of the chain blocks are connected in series to form a strip structure, and each chain is carried. There is a knife sleeve or a tool holder that combines the tools.

It is known that the positioning of the chain block is performed by machining a threaded body on both ends of the shaft, and then locking the threaded body with a nut and completing the assembly and positioning after tightening. However, the manufacture of the threaded body at both ends of the shaft increases the manufacturing process, and the way of driving the nut increases the assembly time, which is not beneficial to the improvement of work efficiency. Moreover, the nut is unscrewed from the threaded body due to improper retraction. The safety concerns generated can be tightened, so the aforementioned positioning method is not a preferred choice but is currently the usual method. Another conventional method is to machine a ring groove at both ends of the shaft, and then the C-shaped buckle is buckled in the ring groove to obtain a positioning effect on the chain block, but the C-type buckle ring must be disassembled and used in conjunction with the operation. The work clamp can be used, and there is also inconvenience to this; secondly, if the ring groove depth on the shaft is insufficient, it will make it difficult for the C-type buckle to fasten the shaft and loosen.

In view of the above, an object of the present invention is to provide an object positioning device which has the effect of convenient and quick installation, and the mounting positioning is ensured to ensure the stability of the components after assembly.

In order to achieve the above object, the present invention provides an object positioning device for confining an object between two fixed positions; it includes a shaft and two restriction members. Wherein the shaft passes through the object and the two ends are respectively provided with at least one positioning groove, the positioning groove is not covered by the object; the two limiting pieces respectively have a plurality of adjacent deformation pieces, and the deformation pieces surround the set And a plurality of connecting ribs respectively passing through the two sockets, and the inner edges of the slabs are embedded in the corresponding positioning slots, so that the objects are limited to the Between two restrictions.

In an embodiment, the two limiting members respectively comprise an outer ring piece, and the deforming pieces are connected to the outer ring piece at one end different from the inner connecting edge, and a slit is formed between the adjacent deformation pieces.

In one embodiment, the outer ring piece is a circular ring body and has a pressing surface facing the object, and the deformation piece is folded outward relative to the outer ring piece in a direction away from the pressing surface.

In an embodiment, the outer ring piece and the deformation piece are integrally formed.

The effect of the present invention is that it is not necessary to over-machine the shaft, and the restraining member can be easily firmly coupled to the shaft without using a special auxiliary tool.

The object positioning device of the present invention is widely used in institutional applications, particularly for confining objects between two fixed positions. Specifically, the object positioning device includes a shaft and two limiting members, wherein the shaft passes through the object and both ends are exposed, and the two limiting members are respectively fixed to the two ends of the shaft, and respectively constitute a fixed position. .

DETAILED DESCRIPTION OF THE INVENTION The present invention will now be described in detail with reference to the preferred embodiments. Referring to FIG. 1 to FIG. 4, an object positioning device according to a preferred embodiment of the present invention includes a shaft 10 and two limiting members 20, wherein the object is a chain block 30 constituting a chain of a chain magazine. , but not limited to this.

The shaft 10 is a round rod body, and a positioning groove 12 and a positioning groove 14 are respectively recessed from a portion near the top end and the bottom end. The positioning groove 12 and the positioning groove 14 may be annular grooves provided along the entire circumference, or A groove segment disposed along the circumference but discontinuous, or a groove arranged in a dot shape; the groove depth of the positioning groove 12 and the positioning groove 14 need not be too deep, and it can be produced by turning or pressurizing.

The restricting member 20 is obtained by processing a metal sheet including an outer ring piece 22 and a plurality of deforming pieces 24 integrally formed. The outer ring piece 22 has a flat annular body and has a pressing surface 22a; the deformation piece 24 has one end connected to the outer ring piece 22, the other end forms an inner connecting edge 24a, and the deformed piece 24 is opposite to the outer ring. The sheet 22 is folded outwardly away from the pressing surface 22a, and the adjacent deformation piece 24 has a slit S therebetween. The slit S is disposed such that the deformation piece 24 can be slightly deformed when subjected to a force. In addition, the inner edges 24a of the deformation pieces 24 collectively surround and define a circular sleeve hole 26.

One side of the chain block 30 is provided with a shaft seat 32, and the other side is provided with two pivoting ears 34, and the two pivoting ears 34 are divided into upper and lower positions. One of the chain blocks 30 is inserted with its axle seat 32 between the two pivots 34 of the other chain block 30. The shaft 10 passes through the shaft seat 32 and the pivoting arm 34 at the same time, and the positioning groove 12 and the positioning groove 14 at both ends of the shaft 10 are respectively located outside the top surface 30a and the bottom surface 30b of the chain block 30 instead of the object (chain block 30). Covered.

The bearing 40 and the spacer 42 are respectively sleeved on both ends of the shaft 10, and then the chain block 30 is faced by the pressing surface 22a of the limiting member 20, and after the sleeve hole 26 is aligned with the shaft 10, the following pressure is applied. The inner edge 24a of the deforming piece 24 of the restricting member 20 can be engaged into the positioning groove of the shaft 10, whereby the restricting member 20 is fixed to the shaft 10 and forms a fixed point, and the adjacent chain block 30 is received by the shaft 10. The restraining members 20 at both ends are resistant to the up-and-down misalignment movement, and thus the purpose of confining the object (chain block 30) between the two fixed positions is achieved. It should be noted that the bearing 40 and the gasket 42 are not essential components of the present invention, and the use end depends on actual needs, or other components may be sleeved on the shaft to reassemble the restriction.

The deformation piece 24 of the restricting member 20 is slightly eversioned according to the assembly direction, and has a slit S between the adjacent deformation pieces 24, which can be slightly deformed when the shaft 10 passes through the sleeve hole 26 to lower the lower portion. The pressure track helps the assembly to go smoothly. At the same time, the slightly deformed deformation piece 24 has a regenerative drive force F which causes the inner edge 24a of the deformation piece 24 to more securely engage the positioning groove.

Therefore, the object positioning device of the present invention does not need to process the threaded body, eliminates cumbersome processing procedures, and does not require special working tongs for assembly, and has the effect of quick installation, which solves the long-standing flaw in the industry.

The above is only a preferred embodiment of the present invention, and equivalent changes to the scope of the present invention and the scope of the patent application are intended to be included in the scope of the present invention.
