[0003] At present, the Chinese utility model with the publication number CN219704748U discloses a positioning device for piston ring processing. However, the existing piston ring support subassembly can support and limit the piston ring, but can only limit and fix the piston ring of a certain type, and cannot support the piston ring of various types, so the practicality is low. After the piston ring is processed, other equipment is needed to assist in taking the piston ring off the support subassembly, and the support subassembly cannot automatically take out the processed piston ring, so the processing efficiency of the piston ring is affected. UTILITY MODEL CONTENTS

[0004] The utility model aims at providing a piston ring support subassembly, which has the advantages of supporting and fixing piston rings of various types and facilitating automatic taking out of the processed piston ring.

[0006] According to the above technical scheme, the conical pressing block is slid into the conical groove by pulling down the pull rod, the inner surface of the strip-shaped groove is supported, and the pull rod is expanded outward and tightly attached to the inner surface of the piston ring. Thus, the piston ring can be supported and fixed according to the size, and the applicability of the support subassembly is improved. When the support of the inner surface of the piston ring by the support cylinder is cancelled by pushing up the pull rod, the ejector rod is slid upward synchronously by the connecting rod, and the piston ring is ejected from the surface of the support cylinder. Thus, the processed piston ring can be conveniently taken off, and the processing efficiency of the piston ring is improved.

[0007] The utility model is further provided as follows: sliding grooves are arranged at both sides of the fixed cylinder, connecting rods are welded at both sides of the surface of the pull rod, and an ejector rod is welded at the end of the two connecting rods away from the pull rod and slidably connected with the sliding groove.

[0008] By pushing the pull rod upwards to drive the ejection rod to slide upwards, the piston ring is ejected from the surface of the supporting cylinder, so that the finished piston ring is conveniently taken off.

[0009] The utility model further sets up: the surface of fixed cylinder top is equipped with thread groove.

[0010] By the technical scheme, the fixed cylinder can be screwed onto the piston ring machining jig for fixation.

[0011] The utility model further sets up: the pull rod and conical briquetting between for die casting integrated structure.

[0012] By the technical scheme, the pull rod and the conical briquetting are tightly connected, and the stability of the pull rod driving the conical briquetting to slide is improved.

[0013] The utility model further sets up: the bottom of pull rod is welded with threaded rod.

[0014] By the technical scheme, the pull rod can be conveniently screwed to the output end of the air cylinder, so that the pull rod is conveniently driven to slide up and down.

[0015] In summary, the utility model has the following beneficial effects:

[0016] 1. By pulling the pull rod downwards to drive the conical briquetting to slide into the inside of the conical groove, the inner surface of the strip-shaped groove is supported, the pull rod is outwardly opened and tightly attached to the inner surface of the piston ring, so that the piston ring can be supported and fixed according to the size, and the applicability of the supporting assembly is improved.

[0017] 2. When the pull rod is pushed upwards to cancel the support of the supporting cylinder to the inner surface of the piston ring, the connecting rod is used to synchronously drive the ejection rod to slide upwards, and the piston ring is ejected from the surface of the supporting cylinder, so that the finished piston ring is conveniently taken off, and the piston ring machining efficiency is improved.

[0021] The utility model will be further explained in detail in combination with the drawings.

[0022] Example 1:

[0023] Reference Figure 1 , Figure 2 A piston ring support assembly, a fixed cylinder 1 is provided with a support cylinder 2 at the top of the fixed cylinder 1, the inside of the fixed cylinder 1 and the support cylinder 2 is slidably connected with a pull rod 3, a strip-shaped groove 4 is opened in the inside of the inner wall of the support cylinder 2, a tapered block 6 is arranged on the top of the pull rod 3, and a tapered groove 5 is opened on the top of the support cylinder 2 and slidably connected with the tapered block 6. By pulling down the pull rod 3 to drive the tapered block 6 to slide into the inside of the tapered groove 5, the inner surface of the strip-shaped groove 4 is supported, and the pull rod 3 is expanded outward and tightly attached to the inner surface of the piston ring. Thus, the support assembly can be supported and fixed according to the size of the piston ring, improving the applicability of the support assembly.

[0024] Reference Figure 1 A threaded groove 10 is opened on the surface of the top of the fixed cylinder 1. The fixed cylinder 1 can be screwed onto the piston ring machining jig for fixation.

[0025] Reference Figure 1 , Figure 2 The pull rod 3 and the tapered block 6 are integrally formed by die casting. The pull rod 3 and the tapered block 6 are tightly connected, improving the stability of the sliding of the pull rod 3 and the tapered block 6.

[0026] Reference Figure 1 , Figure 2 A threaded rod 11 is welded to the bottom of the pull rod 3. The pull rod 3 can be screwed to the output end of the air cylinder, facilitating the upward and downward sliding of the pull rod 3.

[0027] Brief description of the use process: the piston ring is sleeved on the surface of the support cylinder 2, and then the pull rod 3 is pulled down to drive the tapered block 6 to slide into the inside of the tapered groove 5 to support the inner surface of the strip-shaped groove 4. Thus, the pull rod 3 is expanded outward and tightly attached to the inner surface of the piston ring, and then the piston ring is supported and fixed. After the piston ring is machined, the pull rod 3 is pushed upward to make the tapered block 6 slide out of the inside of the tapered groove 5, and then the support of the inner surface of the piston ring by the support cylinder 2 can be cancelled.

[0028] Example 2:

[0029] Reference Figure 1 , Figure 2 A piston ring support assembly, a slide groove 7 is opened on both sides of the inside of the fixed cylinder 1, a connecting rod 9 is welded to the surface of the pull rod 3, and a ejection rod 8 is welded to the end away from the pull rod 3 of the two connecting rods 9 and slidably connected with the slide groove 7. When the support of the inner surface of the piston ring by the support cylinder 2 is cancelled by pushing the pull rod 3 upward, the ejection rod 8 is slid upward synchronously by the connecting rod 9 to eject the piston ring from the surface of the support cylinder 2. Thus, the machined piston ring is conveniently removed, improving the machining efficiency of the piston ring.

[0030] Brief description of use process: by pulling down the pull rod 3, it makes the ejector rod 8 slide down into the fixed cylinder 1 inside to be collected, so that the surface of the supporting cylinder 2 can be sleeved with the piston ring. Then after the piston ring is processed, by pushing up the pull rod 3 to cancel the support of the supporting cylinder 2 to the inner surface of the piston ring, the ejector rod 8 can be driven again by the connecting rod 9 to slide up, so that the piston ring can be ejected from the surface of the supporting cylinder 2.
