Automatic centering cylindrical clamp

Abstract

An automatic centering cylindrical clamp comprises a clamp body, wherein three clamping units are uniformly distributed in a circular hole of the clamp body, and the upper ends of the three clamping units are fixed on the clamp body through springs and screws; one end of each spring is located in a hole of the corresponding clamping unit, and the other ends of the springs are fixed in hinge pins at the head parts of the screws; rubber bands are arranged at the lower ends of the three clamping units in a sleeving manner. Fruit falls into a space among the three clamping units in a free falling state, the fruit all enters the three clamping units after pressed down, and are clamped and fixed by the three clamping units, and circumferential movements of the three clamping units are limited by stopping blocks, the movement of the fruit in a radial direction in the three clamping units is guaranteed, central lines of the fruit are enabled to keep coincidence with the central line of the clamp body, the damage rate and the loss rate of the fruit in a kernel removal process can be lowered, the clamp is applicable to kernel removal processing for products such as stone fruits, is characterized by simple structure, reliable centering and good elasticity, and is convenient to replace.

Description

technical field [0001] The invention relates to an auxiliary device for processing agricultural by-products, in particular to a cylindrical self-centering fixture. Background technique [0002] In the deep processing equipment of jujube, apple, olive, etc., removing the core is a very important process. However, for some existing automatic feeding pitting equipment, due to the influence of some factors such as the shape and size of the fruit, after the feeding is completed, the existing clamps make the fruit centering inaccurate, resulting in the use of a punch to hold the pitting. The crushing rate of the fruit is high, and what has even can't complete the pitting, which causes a large loss of the fruit and increases the production cost, and is not suitable for large-scale production and processing of the fruit. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to propose a cy...
