Description

Technical Field

[0001] The utility model relates to the technical field of oil cylinder processing, in particular to a flash cutting device for an earring on the end of a hydraulic oil cylinder rod. Background Art

[0002] A hydraulic cylinder is a crucial hydraulic actuator that converts hydraulic energy into mechanical energy. It primarily consists of a cylinder head, cylinder cover, cylinder barrel, piston, piston rod, guide sleeve, seals, and tie rods. One end of the piston rod is connected to an earring, and the two components are integrally cast.

[0003] Regarding the above-mentioned related technologies, the inventors found that during casting, because the mold for casting the earring position is composed of two semicircular flat shells, there is a gap between the two semicircular flat shells, which results in two flashes on the outer surface of the earring. When processing the piston rod, the flash must be removed first. Generally, workers use a grinder to grind off the flash. This operation method increases the labor intensity of workers and reduces work efficiency. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a burr cutting device for the earring at the end of a hydraulic cylinder rod, which reduces labor intensity and improves work efficiency.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a burr cutting device for the earring at the end of the hydraulic cylinder rod, comprising: a base plate, one end of the plane on the base plate is connected to a mounting plate, and the other end is connected to a fixed plate, the mounting plate is connected to a telescopic drive rod, the protruding end of the telescopic drive rod is connected to a push plate assembly, the fixed plate is provided with a waist-shaped hole and an open groove, the waist-shaped hole and the open groove are connected, the side of the fixed plate close to the push plate assembly is detachably connected to a cutting plate body, the cutting plate body is provided with a waist-shaped transition hole corresponding to the waist-shaped hole, and the top of the cutting plate body is provided with a giveway groove connected to the waist-shaped transition hole.

[0006] By adopting the above technical solution, when in use, the cylinder rod is moved from top to bottom, and the cylinder rod passes through the opening groove and the give way groove and enters the waist-shaped hole. The cylinder rod is rotated at a certain angle so that the earring on the cylinder rod enters the waist-shaped transition hole. At this time, the two burrs on the outer surface of the earring are in contact with the cutting plate body. The telescopic rod of the telescopic drive rod is operated to extend to drive the push plate assembly to move toward the earring. The push plate assembly applies a certain force to the earring to cause the burrs on the earring to be cut and broken by the cutting plate body. Next, the worker only needs to use a grinder to grind it smooth, which reduces the labor intensity of the workers and improves work efficiency. According to the different specifications of the cylinder rod, waist-shaped transition holes that are compatible with the earrings on the cylinder rod can be processed on different cutting plates, thereby expanding the scope of use.

[0007] In a preferred example, the present invention can be further configured as follows: the pushing plate assembly includes a moving plate, a pushing plate body and two V-shaped limit blocks symmetrically connected to the pushing plate body, the sides of the V-shaped limit blocks are respectively connected to strip plates, two vertical T-slots are spaced apart on the moving plate, first T-bolts passing through the pushing plate body are spaced apart in the vertical T-slots, and the ends of the first T-bolts are threadedly connected with nuts, two transverse T-slots are spaced apart on the pushing plate body, two second T-bolts passing through the strip plates are spaced apart in the transverse T-slots, and the ends of the second T-bolts are threadedly connected with nuts.

[0008] By adopting the above technical solution, the telescopic drive rod drives the push plate assembly to move horizontally, and the earring at the end of the cylinder rod is located between the V-shaped limit blocks. The V-shaped limit blocks limit the earrings, the push plate body applies thrust to the earrings, and the cutting plate body cuts the burrs on the earrings. When cutting the burrs on the cylinder rods of different specifications, it is necessary to process waist-shaped transition holes and give way grooves on different cutting plate bodies, and then use the cutting plate body to replace the cutting plate body fixed on the fixed plate. Since there may be errors in the positions of the waist-shaped transition holes and the give way grooves, the nuts on the first T-shaped bolts and the nuts on the second T-shaped bolts are loosened, and the push plate body is operated to move in the vertical direction and the V-shaped limit blocks are operated to move in the horizontal direction, so that the two V-shaped limit blocks can be smoothly clamped on the outer sides of the earrings to limit them, that is, the push plate body can smoothly drive the cylinder rod of the oil cylinder to move.

[0009] In a preferred example, the present invention can be further configured as follows: the hardness of the cutting plate body is greater than the hardness of the cylinder rod.

[0010] By adopting the above technical solution, since the hardness of the cutting plate is greater than the hardness of the cylinder rod, the wear of the cutting plate when cutting the burrs on the earrings is reduced, the cutting effect is enhanced, and the service life of the cutting plate is extended.

[0011] In a preferred example, the present invention can be further configured as follows: an L-shaped support plate is connected to one end of the bottom plate close to the fixed plate.

[0012] By adopting the above technical solution, after the flash on the cylinder rod is cut, one end of the cylinder rod falls on the L-shaped support plate, which plays a role in connecting the cylinder rod.

[0013] In a preferred example, the present invention can be further configured as follows: guide rods fixed to the mounting plate are respectively provided on both sides of the telescopic drive rod, and one end of the guide rod is connected to the push plate assembly.

[0014] By adopting the above technical solution, the push plate assembly can smoothly push the cylinder rod through the action of the guide rod.

[0015] In a preferred example, the present invention can be further configured as follows: the telescopic drive rod is an oil cylinder or a pneumatic cylinder.

[0016] By adopting the above technical solution, the structure is simple and the installation is easy.

[0017] In summary, the present invention has at least one of the following beneficial technical effects:

[0018] The telescopic rod of the telescopic driving rod is extended to drive the push plate assembly to move toward the earring. The push plate assembly applies a certain force to the earring, causing the burrs on the earring to be cut and broken by the cutting plate. Then, the worker only needs to use a grinder to grind it smooth, which reduces the labor intensity of the workers and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
