[0006] The purpose of this disclosure can be achieved through the following technical solutions:

[0007] A retaining ring pressing head mechanism for a hole of an integrated shrink sleeve for automated equipment, comprising:

[0008] A pressure head seat, the pressure head seat comprising an upper end, a lower end, and a connecting portion fixedly connected between the upper end and the lower end, the upper end and the lower end are both provided with an upper through hole and a lower through hole arranged in a vertical direction;

[0009] A quick-change connecting rod, wherein the quick-change connecting rod is slidably connected in the upper through hole, a spring is sleeved on the outer side of the quick-change connecting rod, and a pressure head is fixedly connected to the lower end of the quick-change connecting rod;

[0010] The shrink sleeve is fixedly connected in the lower through hole at the lower end.

[0011] The above technical solution, its principle and technical effect:

[0012] The operator places the retaining ring for the hole to be pressed in parallel on the upper end of the shrink sleeve, and drives the quick-change connecting rod downward through the electric cylinder or air cylinder. The pressure head seat moves downward under the elastic force of the spring until its lower end contacts the workpiece and then stops moving. The quick-change connecting rod continues to press down, the spring contracts, and the pressure head presses the retaining ring for the hole into place through the shrink sleeve.

[0013] In a preferred example, the utility model can be further configured as follows: the upper through hole includes a first channel, a second channel and a third channel arranged in sequence from top to bottom, the inner diameter of the first channel is larger than the inner diameter of the second channel, and smaller than the inner diameter of the third channel, the quick-change connecting rod passes through the first channel and is slidably connected to the second channel, the spring is located in the first channel, and the lower end contacts the upper end surface of the second channel, and the pressure head is slidably connected to the third channel.

[0014] In a preferred example, the present invention can be further configured as follows: the first hole channel, the second hole channel, the third hole channel and the lower through hole are coaxially arranged.

[0015] In a preferred example, the utility model can be further configured as follows: a head having a diameter larger than that of the quick-change connecting rod is fixedly connected to the top end of the quick-change connecting rod, and the upper end of the spring is in contact with the head.

[0022] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0023] Fixed connection refers to a connection in which parts or components are fixed without any relative movement. There are two types of connection: detachable and non-detachable.

[0024] (1) A removable connection is a connection that uses screws, splines, wedge pins, etc. to hold parts together. This type of connection can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0025] (2) Non-detachable connections mainly refer to welding, riveting and tenoning. Since they need to be disassembled by forging, sawing or oxygen cutting for maintenance or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.).

[0026] A threaded connection refers to a detachable connection in which the connected parts are connected together using threaded parts (or the threaded parts of the connected parts).

[0027] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.

[0028] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.

[0029] Beneficial effects of the present disclosure:

[0030] The utility model integrates a shrink sleeve into a pressing head on the basis of a retaining ring for a press-fit hole, and increases a retaining ring orientation function, thereby avoiding problems such as manual repeated placement of the shrink sleeve and unstable placement, and is easy to operate, thereby improving work efficiency and product qualification rate.
