Background

The crankshaft and connecting rod transmission is a conventional mode of a piston type press, a punch press and other similar transmission equipment, after the crankshaft and the connecting rod are connected and installed, during operation, the crankshaft rotating in an eccentric mode drives the connecting rod to do continuous and reciprocating telescopic motion, so that the connecting rod drives a connecting module to work, a copper sleeve is arranged in the connection, in the conventional process, the structure of the copper sleeve consists of an upper half ring and a lower half ring, and the upper half ring and the lower half ring are connected in a mortise and tenon mode, after the upper half ring and the lower half ring are in mortise and tenon joint, the upper half ring and the lower half ring form an integral copper sleeve, the radial precision and the ovality of the crankshaft connecting copper sleeve and the roundness are determined by mortise and tenon joint, namely, the form and position tolerance and the error of the mortise and tenon joint directly determine various precisions of the copper sleeve, and the inevitable existing defects are that: firstly, the roundness precision of the copper sleeve is reduced, and the crankshaft is used for running in after the copper sleeve continuously works for a period of time, so that the fit clearance between the crankshaft and the copper sleeve is increased and irregular and uneven; secondly, the manufacturing of the copper sleeve has great technical difficulty and high failure rate; and thirdly, in continuous operation, deformation caused by expansion with heat and contraction with cold of the copper sleeve can not be adjusted in a self-adaptive manner, and the seizure probability between the copper sleeve and the crankshaft is increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide a copper sleeve of a swinging connecting rod with durability and self-adjustment function, wherein a copper sleeve body internally provided with a connecting hole consists of an upper half ring and a lower half ring which are split and then decomposed integrally and have the same shape, the upper half ring and the lower half ring are both provided with oil injection holes, the outer end orifice of each oil injection hole is provided with an inclined hole, and the outer circumferences of the upper semi-ring and the lower semi-ring are provided with positioning holes, the connecting hole wall of the copper bush body is provided with a horizontal inner oil groove, the inner oil groove is communicated with the oil injection hole, when in use, the utility model is a split structure, which is applied to the transmission connection of the crankshaft and the swing connecting rod of equipment such as a continuously rotating press or punch, the self-adaptive arc stretching type adjustment avoids the problem that the integral copper bush is heated continuously to cause the deformation of the inner and outer circumference diameters and the reduction of the fit clearance to cause seizure due to the continuous operation and the heat expansion deformation.

In order to achieve the purpose, the technical scheme of the utility model is as follows: a swinging connecting rod copper sleeve with durability and self-adjusting function comprises a copper sleeve body, wherein the copper sleeve body with a connecting hole inside is composed of an upper half ring and a lower half ring which are split and decomposed integrally;

the specifications of the upper half ring and the lower half ring are the same, the upper half ring and the lower half ring are both provided with oil injection holes, the outer end orifices of the oil injection holes are provided with inclined holes, and positioning holes are arranged on the outer circumferences of the upper half ring and the lower half ring;

an inner oil groove is formed in the connecting hole wall of the copper sleeve body and communicated with the oil injection hole;

after the upper half ring and the lower half ring are installed with the connecting rod, a split groove is formed between the upper half ring and the lower half ring.

Further, the inner oil groove is shaped like a horizontal 8 of infinity, and forms a lubricating closed loop with the oil groove in the upper semi-ring. Thereby achieving the integral lubrication effect

The utility model has the beneficial effects that: when the copper sheathing body of open structure is used when the bent axle of equipment such as continuous rotatory press, press or punch press is connected with the transmission of swing connecting rod, the arc stretching adjustment that can the self-adaptation is because of continuous operation thermal expansion deformation, avoids integral copper sheathing continuous operation to generate heat and leads to inside and outside circumference diameter deformation and produce the fit clearance and reduce and lead to stinging dead problem.

fig. 3 is a bottom view of the upper half ring of fig. 1.

In the figure: the copper bush comprises a copper bush body 1, an upper semi-ring 2, a lower semi-ring 3, a split groove 4, an inner oil groove 5, a positioning hole 6, an oil filling hole 7, an inclined hole 8 and a connecting hole 9.

Detailed Description

The technical solution of the present invention will be further specifically described below by way of examples and with reference to the accompanying drawings.

As shown in fig. 1 to 3, a swinging connecting rod copper sleeve with durability and self-adjusting function is provided, wherein a copper sleeve body 1 provided with a connecting hole 9 therein is composed of an upper half ring 2 and a lower half ring 3 which are decomposed after the whole copper sleeve body 1 is split, a split groove 4 is formed between the upper half ring 2 and the lower half ring 3 after the upper half ring 2 and the lower half ring 3 are installed with a connecting rod, the split groove 4 is generally smaller than 3mm, and a deformation accommodating space caused by thermal expansion of the copper sleeve due to heating in continuous operation can be satisfied;
