Description

A centering clamping device for an elastic collet

technical field

The utility model relates to a centering and clamping device for an elastic collet, which belongs to the technical field of mechanical processing.

Background technique

In mechanical processing technology, it is a common process to process workpieces with thin-wall sleeves. Usually, the workpieces are clamped on the three-chuck of the lathe, and the borings or outer circles are processed. After this method, the processing quality of the workpieces is difficult. Guaranteed and low productivity, in order to save production costs, ensure product processing quality, and improve production efficiency, it is necessary to design a centering clamping device for collets.

Utility model content

In order to solve the above problems, the purpose of this utility model is to solve the shortcomings of the above-mentioned prior art. The purpose of this utility model is to provide a centering and clamping device for a collet.

In order to solve the above problems, the utility model is realized through the following technical solutions: a centering and clamping device for an elastic collet, which is composed of a taper handle, a workpiece, an inner clamping collet, a guide pin, an open gasket, a tightening Composed of solid nuts and tapered expansion sleeves; it is characterized in that: the taper shank is objectively installed in the spindle hole of the national first bed; the workpiece is installed on the outer cylindrical surface of the inner clip type spring chuck; the described The inner clip type collet is installed on the taper shaft and the tapered expansion sleeve in the middle of the taper shank; the taper expansion sleeve has a keyway and is installed on the cylinder at the right end of the taper shank; the guide pin is installed on the taper shank On the cylinder at the right end, the pin diameter is equal to the groove width on the tapered expansion sleeve; the split washer and fastening nut are installed on the right end of the taper handle. During processing, insert the workpiece into the outer cylindrical surface of the elastic chuck, and make the left end surface of the workpiece close to the end surface of the mandrel. Tighten the nut, push the conical expansion sleeve to move to the left, so that the outer diameter of the elastic chuck increases, clamp the workpiece from the inner hole, and perform turning processing. After the processing is completed, loosen the nut, and the elastic chuck returns to its original state , the workpiece can be removed.

The beneficial effects of the utility model are: a centering and clamping device for an elastic collet, which has the advantages of simple structure, quickness, accuracy, high precision, safety and reliability, and easy operation.

Description of drawings

Figure 1 is a schematic structural view of a centering and clamping device for an elastic collet.

Detailed ways

As shown in Figure 1, a centering clamping device for an elastic collet is composed of a tapered handle 1, a workpiece 2, an inner clip spring collet 3, a guide pin 4, an open washer 5, a fastening nut 6 and an awl Form expansion sleeve 7; It is characterized in that: the taper shank 1 objectively exists in the spindle hole of the national first bed; the workpiece 2 is installed on the outer cylindrical surface of the inner clip spring chuck 3; the The inner clip type collet 3 is installed on the tapered shaft and the tapered expansion sleeve 7 in the middle of the tapered handle 1; the tapered expansion sleeve 7 has a keyway and is installed on the cylinder at the right end of the tapered handle 1; the guide The pin 4 is installed on the cylinder at the right end of the tapered handle 1 and the pin diameter is equal to the groove width on the tapered expansion sleeve 7; the split gasket 5 and the fastening nut 6 are installed at the right end of the tapered handle 1. During processing, insert the workpiece into the outer cylindrical surface of the elastic chuck, and make the left end surface of the workpiece close to the end surface of the mandrel. Tighten the nut, push the tapered expansion sleeve to move to the left, so that the outer diameter of the elastic chuck increases, clamp the workpiece from the inner hole, and perform turning processing. After the processing is completed, loosen the nut, and the elastic chuck returns to its original state , the workpiece can be removed.

The utility model has been disclosed above with preferred implementations, but it is not intended to limit the utility model. All technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the utility model.
