Background

Sealing rings are commonly used sealing elements, especially for the fitting of shaft/shaft-like workpieces to bores. At present, the traditional assembling mode of the sealing ring is manual assembling, tools such as tweezers are adopted to stretch the sealing ring and the sealing ring is installed in a groove on the outer side of a rod/shaft workpiece, but the sealing ring is not large in size and even can be smaller in size in special occasions, so that the assembly is very inconvenient and the efficiency is very low.

In order to solve the problems of inconvenient manual assembly and low efficiency, the Chinese patent discloses a sealing ring assembly device with application number 201020669655.5, which comprises a main push cylinder, a guide sleeve, a push rod and a conical chuck, wherein one end of the guide sleeve is connected to the head of the main push cylinder, the other end of the guide sleeve is a claw, and a cylinder arm of the guide sleeve is provided with a feed inlet; the push rod is hollow, a plurality of long holes communicated with the hollow inner cavity are formed in the rod arm along the extension direction and extend to the end part, the push rod is positioned in the guide sleeve, one end of the push rod is connected with the cylinder rod of the main push cylinder, and the other end of the push rod is positioned at one side of the feed inlet close to the main push cylinder; the conical chuck is arranged in a jaw of the guide sleeve, one end of the conical chuck is smaller than the inner diameter of the sealing ring to be assembled, the other end of the conical chuck is connected with the end part of the workpiece to be assembled, the outer edge surface of the conical chuck is in smooth transition with the outer edge surface of the workpiece, and the stroke distance of the main push cylinder is matched with the distance from the end part of the push rod to the outer edge surface of the workpiece. When the sealing ring pushing device is used, a sealing ring to be assembled falls into the guide sleeve from a feeding hole in the guide sleeve, the sealing ring is pushed by the push rod to move forwards along the conical chuck, the end part of the push rod and the sealing ring are simultaneously opened due to the taper of the outer side of the conical chuck, the push rod continues to push forwards to open the clamping jaws at the end part of the guide sleeve, the sealing ring reaches a smooth transition section where the conical chuck is connected with a workpiece, and the sealing ring can fall into a groove in the middle of the workpiece due to the fact that the sealing.

However, in practical use, it has been found that the push rod and the sealing ring are spread apart in the guide sleeve, which means that the diameter of the inner bore of the guide sleeve is larger than the outer diameter of the sealing ring. The sealing ring falls into the guide sleeve from the feeding hole in a vertical state, so that the sealing ring still keeps in a vertical state after falling into the guide sleeve due to the large inner space of the guide sleeve, namely the sealing ring is likely to deflect or the angle between the center of the sealing ring and the center line of the push rod is greatly different after falling into the guide sleeve, and at the moment, the push rod is pushed out, so that the end face of the push rod and the sealing ring cannot be effectively contacted, and the sealing ring cannot be smoothly pushed out along the conical chuck, and further the assembly failure of the sealing ring is caused.

In order to solve the problems of low assembling power and poor reliability of the sealing ring, some assembling devices/mechanisms have been proposed which use a manipulator to clamp and assemble the sealing ring, such as a material taking and assembling integrated device of the sealing ring disclosed in patent application No. 201610769010.0, an automatic assembling device and an assembling method of the valve stem sealing ring disclosed in patent application No. 201310296397.9, and the like.

By means of the abutting of the sealing ring 14 and the end surface of each lug 2c, the sealing ring 14 can be always kept in a vertical state in the material guiding channel 2a, so that the sealing ring 14 can not deflect.

Then, the push rod 3 is controlled to move horizontally in a manual or intelligent mode (such as an air cylinder, a motor and the like). The conical guide block 8 is fixed, and the conical guide block 8 is in conical surface contact with each pushing part 3a1, so that each pushing part 3a1 is expanded outwards under the action of the conical surface when the push rod 3 translates. When the push rod 3 translates, the material supporting part 3a13 fixedly connected with the end surface of each material pushing part 3a1 is inserted into the inner side of the sealing ring 14, and simultaneously, the end surface of each material pushing part 3a1 passes between two adjacent convex blocks 2c and is abutted against the sealing ring 14. With the continuous translation of the push rod 3, each pushing part 3a1 pushes the sealing ring 14 to push through each bump 2c on the block group two 13 and finally push out of the discharging channel 2b, and simultaneously each pushing part 3a13 expands outwards along with each pushing part 3a1 to prop open the sealing ring 14.

The inner diameter of the expanded sealing ring 14 is larger than the outer diameter of the workpiece at the mounting point, so that the plunger 3 can transport the sealing ring 14 to the mounting point of the workpiece without interference. In order to ensure that the sealing ring 14 can be smoothly mounted on the workpiece, a blocking mechanism may be provided in a direction perpendicular to the workpiece, and the blocking mechanism may be composed of a cylinder and a blocking rod. When the push rod 3 translates to the position where the expanded sealing ring 14 is located at the assembly position of the workpiece, the control cylinder drives the blocking rod to be inserted between two adjacent extension strips 3a12, and then the push rod 3 is controlled to reset, so that the sealing ring 14 is separated from the push rod 3 due to the abutting of the blocking rod, and the sealing ring 14 which loses the action of each material supporting part 3a13 retracts under the action of the elasticity of the sealing ring 14 and is clamped at the assembly position of the workpiece.
