Description

Gapless aperture type clamping device

Technical Field

The invention relates to the field of clamps, in particular to a gapless light ring type clamping device.

Background

In the plastic pipe production line, a matched cutting device is needed for cutting continuously produced products in a segmented manner. The cutting equipment comprises clamping devices which are respectively positioned at an inlet and an outlet of the cutting equipment, and is used for ensuring that plastic pipe products do not vibrate when cutting, and meanwhile, enough friction force is provided for driving the cutting machine to follow the plastic products to synchronously follow.

The clamping devices commonly available on the market at present are divided into the following types:

1. the aluminum half clamping mode is as follows: the structure of the aluminum half clamping block is two groups of semicircular aluminum half clamping blocks, and the mode of compressing the aluminum half clamping blocks up and down by using an air cylinder is adopted. The advantages are that: the structure is simple, the overhaul is convenient, and the concentricity is high; the disadvantages are as follows: a set of half clamping blocks is required to be matched for each specification, and specification conversion is complicated;

2. three-point clamping mode: the structure of the planet chipless cutting machine is that an upper air cylinder compresses tightly, and a lower electric tray lifts. The advantages are that: a set of clamping blocks is not required to be matched for each specification, and the clamping blocks can be replaced only when the span is too large, so that the specification conversion time is greatly saved; the lower electric tray can play a role in supporting pipes. The disadvantages are as follows: sealing can not be realized, and the sealing can only be used on chipless cutting; the lower powered tray still requires manual adjustment of position.

3. Conventional rotary clamping manner: commonly found on planetary chipless cutting equipment. The advantages are that: the specification conversion does not need to replace the clamping block, and the basic specification can be covered; the disadvantages are as follows: the sealing can not be realized, and the sealing can only be used on chipless cutting equipment; the safety is poor, and the protection cannot be realized.
