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

A kind of cylindrical automatically centering fixture

Technical field

The present invention relates to the auxiliary implement of a kind of agricultural byproducts processing, particularly to a kind of cylindrical automatically centering fixture.

Background technology

In the deep processing equipment of Fructus Jujubae, Fructus Mali pumilae, Fructus Canarii albi etc., enucleation is a critically important operation. But the enucleation equipment for more existing automatic chargings at present, impact due to some factors such as the shape of fruit, sizes, after feeding completes, existing fixture makes fruit centering inaccurate, causing that to adopt drift to hold the broken rate of fruit during core in the month high, even cannot completing of having rushes core, causes fruit loss big, production cost increases, and is not suitable for the large-scale production processing of fruit.

Summary of the invention

In order to overcome above-mentioned the deficiencies in the prior art, it is an object of the invention to propose a kind of cylindrical automatically centering fixture, fruit broken rate in After Enucleation and the proportion of goods damageds can be reduced, enucleation suitable in kernel approaches product is processed, and has simple in construction, is conveniently replaceable, feature reliable, good springiness of feeling relieved.

To achieve these goals, the technical solution used in the present invention is:

A kind of cylindrical automatically centering fixture, including clamp body 3, three clampers 2 it are evenly distributed with in the circular hole of clamp body 3, the upper end of three clampers 2 is fixed on clamp body 3 by spring 6, screw 7, one end of spring 6 is placed in the hole of clamper 2, the other end of spring 6 is fixed in the bearing pin of screw 7 head, and the lower end of three clampers 2 is cased with rubber band 5.

The first half of described clamper 2 is cone, and the latter half of clamper 2 is cylinder.

The height of described clamper 2 is more than the height of fruit.

Described clamper 2, is separated by the block 8 in the circular trough of clamp body 3 upper end between each two clamper upper flange, and described block 8 is fixed in the circular trough of clamp body 3 upper end, is uniformly distributed.

Described clamp body 3 is fixed with upper cover 1.

Owing to the present invention adopts three clampers to clamp fruit, three clamper lower ends rely on rubber band radially to draw in, upper end relies on spring radial compression, ensure that fruit be clamped fixing while, can also ensure that the fruit that diameter is less will not pass through to leak down, it is achieved that the self-centering clamping of fruit;Three clampers adopt the structure of cylindricality under epicone, it is simple to different size of fruit can both fall between three clampers smoothly; The circumference that block in the circular trough of clamp body upper end limits three clampers is mobile, it is ensured that fruit moves radially after pressure down in three clampers, makes the centrage of fruit keep overlapping with the centrage of clamp body.

Accompanying drawing explanation

Fig. 1 is the overall structure schematic diagram of the present invention.

Fig. 2 is the A-A sectional view of Fig. 1.

Fig. 3 is the partial enlarged view at I place in Fig. 1.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is described in further detail.

Referring to Fig. 1, a kind of cylindrical automatically centering fixture, including clamp body 3, three clampers 2 it are evenly distributed with in the circular hole of clamp body 3, described clamper 2 time processing shapes, then circumferentially cut after three equal parts again, spring 6 is passed through in the upper end of clamper 2, screw 7 is fixed on clamp body 3, one end of spring 6 is placed in the hole of clamper 2, the other end of spring 6 is fixed in the bearing pin of screw 7 head, the lower end of three clampers 2 is cased with rubber band 5, under rubber band 5 contraction state, fruit 4 can not only be made to be fixedly clamped, can also ensure that the fruit 4 that diameter is less will not pass through to leak down.

The first half of described clamper 2 is cone, it is simple to different size of fruit 4 can both fall between three clampers 2 smoothly; The latter half of clamper 2 is cylinder, it is achieved the self-centering clamping of fruit.

The height of described clamper 2 is slightly larger than the height of fruit, when fruit falls in three clampers 2 via free falling body state, under the effect of self gravitation, at least the 1/2 of fruit can enter in three clampers 2, after simple pressure down, it is possible to ensure that fruit 4 fully enters three clampers 2.

Described clamp body 3 is fixed with upper cover 1, to prevent spring 6 from deviating from the course of the work.

Referring to Fig. 2, described clamper 2, separated by the block 8 in the circular trough of clamp body 3 upper end between each two clamper upper flange, described block 8 is fixed in the circular trough of clamp body 3 upper end, being uniformly distributed, the circumference limiting three clampers 2 is mobile, it is possible to ensure that fruit 4 moves radially after pressure down in three clampers 2, under the dual function of spring 6 and rubber band 5, the centrage of fruit 4 is made to keep overlapping with the centrage of clamp body 3.

The operation principle of the present invention:

Fruit 4 falls in the space between three clampers 2 in free falling body state, after pressure down, fruit 4 is made to fully enter in three clampers 2, by three clampers 2, fruit 4 is fixedly clamped, the circumference being limited three clampers 2 by block 8 is mobile, ensure that fruit 4 moves radially in three clampers 2, make the centrage of fruit 4 keep overlapping with the centrage of clamp body 3.
