Description

Shrapnel for telescopic shield

The invention relates to an accessory for a machine tool, in particular to an elastic piece for a telescopic shield.

In general machine tools, in order to avoid contamination of components such as lead screws and linear slides by chips, cutting fluid, dust, etc., most of them will be equipped with a telescopic cover between the moving part and the fixed part, such as TW Patent No.M498081 reveal.

The telescopic cover disclosed in TW Patent No. M498081 and other patents includes a scale unit, a support unit and a shielding unit. The supporting unit has a plurality of supporting plates respectively connected to the connecting ends, the shielding unit is connected to the scale unit and the supporting unit and a flexible cloth is used. This telescopic cover can achieve the intended purpose of shielding and telescopic.

In addition, as shown in FIGS. 1 and 2, a conventional elastic sheet 1 installed on the above-mentioned telescopic cover has a pair of elastic plates 101 connected to each other and fixed between two adjacent support plates 2, and a shielding unit 3 The cross section is wavy and is connected to the top edges of the support plates 2. The elastic plates 101 each have a fixed end 102 which is fixed relative to the support plates 2 and a connecting end 103 which is opposite to the fixed end 102. The connecting ends 103 are fixed to each other, and the elastic piece 1 is substantially V-shaped.

Although this spring piece 1 is installed between two adjacent support plates 2 and the elastic force generated by the spring pieces 1 can be used to keep the two adjacent support plates 2 in a constant separation trend, but because of frequent operations, it is possible As a result, the joints 103 of the elastic plates 101 are easily broken.

Furthermore, the connecting ends 103 of the elastic plates 101 are connected by riveting (or welding), and the steps of riveting or welding are added, which will increase the manufacturing cost.

Therefore, the object of the present invention is to provide an elastic sheet for a telescopic shield which can improve the structural strength and reduce the cost.

Therefore, the new type of shrapnel for a telescopic shroud also includes a plurality of support plates disposed at intervals along a horizontal axis and a shielding unit connected to the support plates. The shrapnel is connected to two adjacent supports. Between the plates, a pair of elastic plates and a connecting plate are provided. The elastic plates are oppositely disposed and are respectively fixed to two adjacent supporting plates. Each elastic plate has a fixed end fixed to the corresponding supporting plate. And a connecting end opposite to the fixed end, the connecting ends of the elastic plates are opposed and spaced apart, the connecting plate is connected between the elastic plates, and the cross-sectional shape of the connecting plate parallel to the transverse axis is circular. And has two side end portions which are oppositely arranged and are respectively connected to the connecting ends of the elastic plates.

The utility model has the advantages that the connecting plate is used to connect between the elastic plates, and the cross-sectional shape of the connecting plate parallel to the transverse axis is arc-shaped, which can make the overall structure of the elastic piece have good strength. The elastic sheet can be easily demolded and manufactured, and the manufacturing cost can be reduced.

Referring to FIG. 3, an embodiment of the novel shrapnel 10 for the telescopic shroud 100 according to the present invention. The telescopic shroud 100 further includes a plurality of support plates 20 disposed at intervals along a horizontal axis X, and a support plate 20 connected to the support plates 20 The shielding unit 30, and most of the fixing elements 40.

The elastic piece 10 is connected between two adjacent support plates 20 and includes a pair of elastic plates 11 and a connecting plate 12. The elastic piece 10 in this embodiment is made by an integral molding method, and the elastic plates 11 and the connecting plate 12 interposed between the elastic plates 11 are integrated into one body.

With reference to FIG. 4 and FIG. 5, the elastic plates 11 are oppositely disposed and are respectively fixed to two adjacent support plates 20. Each elastic plate 11 has a fixed end 111 fixed to the corresponding support plate 20 and an opposite one. A connecting end 112 between the fixed end 111 and a reinforcing rib 113 extending between the fixed end 111 and the connecting end 112 and extending from the fixed end 111 toward the connecting end 112. Each elastic plate 11 also has an outer side surface 114 and an inner side surface 115 opposite to the outer side surface 114. The reinforcing rib 113 protrudes from the inner side surface 115 and defines a groove with an opening corresponding to the outer side surface 114. 116. In addition, each elastic plate 11 also has a main plate portion 117 and a connecting plate portion 118 intersecting and connected to the main plate portion 117. The fixed end 111, the connecting end 112, the reinforcing rib 113, the outer side surface 114, the The inner side surface 115 and the groove 116 are provided in the main plate portion 117, and the connecting plate portion 118 also has two perforations 119. In addition, the connecting ends 112 of the elastic plates 11 are opposite and spaced apart, and the connecting ends 112 are curved. The fixing elements 40 may be rivets, penetrate the through holes 119, and fix the elastic plates 11 to the supporting plates 20.

The connecting plate 12 is connected between the elastic plates 11, and the cross-sectional shape of the connecting plate 12 parallel to the transverse axis X is arc-shaped, and has two connections that are oppositely arranged and are respectively connected to the elastic plates 11.端 112 的 边 端 部 121。 The end portion 121 of the end 112. The curved direction of the connecting ends 112 is opposite to the curved direction of the connecting plate 12.

In order to further understand the function of the components of the new model, the use of technical means, and the expected effects, I will explain the following description, I believe that we can have a deeper and specific understanding of the new model.

As shown in FIG. 3 again, when the elastic sheet 10 is installed between two adjacent support plates 20 and the telescopic shield 100 is driven by an external force to contract in the horizontal axis X, and the support plates 20 are moved toward each other. Recently, the fixed ends 111 of the elastic plates 11 of the elastic sheet 10 also approach each other, and the connecting plates 12 connected between the elastic plates 11 are squeezed and contain a releasable elastic force.

When the telescopic shroud 100 is stretched along the horizontal axis X by the external force and the support plates 20 are separated from each other, the action of the telescopic shroud 100 can be used to make the action of the telescopic shroud 100 even more. Smooth and sure.

And during the expansion and contraction of the telescopic shield 100 described above, the connection plate 12 is used to connect between the elastic plates 11, and the cross-sectional shape of the connection plate 12 parallel to the transverse axis X acts as an arc. The connecting plate 12 will be elastically deformed as the fixed ends 111 of the elastic plates 11 approach and move away. Even if the operation is performed frequently, the connecting plates 12 located between the connecting ends 112 of the elastic plates 11 are not easily generated. fracture. Furthermore, by using the arrangement of the reinforcing ribs 113, the structural strength of the elastic plates 11 is good, and the service life can be extended.

In addition, by using the elastic piece 10 to be manufactured in an integrated manner, and the elastic plates 11 and the connecting plate 12 are integrated into one body, the production of the elastic piece 10 is relatively easy, the process is simple, and the manufacturing cost is low.

In summary, the new type of shrapnel used in the telescopic shield not only enables the support plates 20 to achieve the expected rebound effect, but also the overall structure of the shrapnel 10 is good in strength, simple in structure, easy to manufacture, and can extend the service life. Reducing manufacturing costs can indeed achieve the purpose of new cost.

However, the above are only examples of the new model. When the scope of implementation of the new model cannot be limited by this, any simple equivalent changes and modifications made in accordance with the scope of the patent application of the new model and the content of the patent specification are still Within the scope of this new patent.
