Description

Technical Field

[0001] The utility model relates to a pickling hanger, belonging to the technical field of bearing processing. Background Art

[0002] In the process of manufacturing bearings, the bearing rings need to be pickled. Pickling is a method of cleaning metal surfaces by using an acid solution to remove scale and rust on the surface of steel. The bearing rings are often hung on a hanger, and then the hanger with multiple bearing rings is lowered into the pickling tank. After the bearing rings are soaked in the pickling liquid in the pickling tank for a period of time, the bearing rings need to be transferred from the pickling tank to the next process. During the transfer process, in order to prevent the pickling liquid attached to the surface of the bearing ring and the surface of the hanger from dripping randomly, it takes a long time to suspend the bearing ring on the upper side of the pickling tank to wait for the pickling liquid on the surface of the bearing ring and the hanger to drip completely, which affects the pickling efficiency. Therefore, it is necessary to design a pickling hanger that does not need to spend a lot of time to suspend the bearing ring on the upper side of the pickling tank. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a pickling hanger to solve the problems raised in the above background technology. The utility model does not need to spend much time to suspend the bearing ring on the upper side of the pickling tank, thereby improving work efficiency.

[0004] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a pickling hanger, including a hanging plate, a plurality of evenly arranged suspension rods are installed on the lower surface of the hanging plate, a limit rod for limiting the position of the bearing ring is connected and fixed to the lower end of the suspension rod, a limit plate is installed at the end of the limit rod away from the suspension rod, a tube sleeve is provided on the suspension rod, a rubber sleeve is pasted on the inner surface of the tube sleeve, the rubber sleeve is wrapped around the suspension rod and fits the surface of the suspension rod, a rectangular frame is connected and fixed to the outer surface of the tube sleeve, a horizontal plate is inserted in the rectangular frame, a connecting rod is connected and fixed to one end of the horizontal plate, and the lower end of the connecting rod is installed at the bottom of a liquid collecting box for collecting pickling liquid.

[0005] Furthermore, a rib plate arranged along the length direction of the hanging plate is connected and fixed to the upper surface of the hanging plate, and two hanging holes are provided on one side of the rib plate.

[0006] Furthermore, a connecting plate is connected and fixed to the lower end of the connecting rod, and the connecting plate is connected and fixed to the round table through a plurality of screws, and the round table is fixed to the bottom of the liquid collecting box.

[0007] Furthermore, the frustum is arranged in the shielding sleeve, the lower end of the shielding sleeve is open and is equipped with a sealing ring that contacts the bottom of the liquid collecting box, a threaded hole is opened in the middle of the upper surface of the shielding sleeve, and the outer surface of the lower end of the connecting rod is processed with an external thread that matches the threaded hole, and one end of the connecting rod with the external thread is threadedly connected in the threaded hole.

[0008] Furthermore, a liquid drain port is installed at the bottom of the liquid collecting box, and a threaded cover is threadedly connected to the lower end of the liquid drain port.

[0009] Furthermore, a baffle is fixedly connected to one end of the transverse plate away from the connecting rod, and the baffle and the transverse plate are arranged perpendicular to each other.

[0010] Furthermore, a reinforcing rib is connected and fixed to the upper surface of the rectangular frame, and the reinforcing rib is connected and fixed to the tube sleeve.

[0011] Furthermore, a blind hole is provided on the outer surface of the lower end of the suspension rod, and one end of the limiting rod is connected and fixed in the blind hole.

[0012] Beneficial effects of the utility model:

[0013] 1. The rubber sleeve pasted on the inner surface of the sleeve is wrapped around the suspension rod, which increases the friction coefficient between the sleeve and the suspension rod without affecting the movement of the sleeve along the suspension rod and the rotation of the sleeve around the suspension rod, so as to limit the relative position of the sleeve and the suspension rod, insert the cross plate in the rectangular frame, and adjust the position of the cross plate along the rectangular frame, so as to adjust the relative position of the liquid collecting box and the suspension rod.

[0014] 2. Hang the bearing ring on the structure formed by the limit rod and the limit plate, and then lower the hanging plate, so that the bearing ring is immersed in the pickling liquid in the pickling tank. At this time, the cross plate is overlapped on the upper edge of the pickling tank and the liquid collecting box is outside the pickling tank. When the bearing ring is taken out of the pickling liquid, the liquid collecting box is rotated, and then the liquid collecting box drives the sleeve to rotate around the hanging rod through the connecting rod, cross plate, and rectangular frame, so that the liquid collecting box moves to the bottom of the bearing ring. At this time, the pickling liquid on the surface of the bearing ring, the surface of the limit rod and the lower end surface of the hanging rod will drip into the liquid collecting box, so as to realize the centralized collection of the pickling liquid. There is no need to spend much time to suspend the bearing ring on the upper side of the pickling tank, thereby improving work efficiency.

On the one hand, the assembly of the connecting rod and the liquid collecting box is completed, and on the other hand, the thickness of the installation screw part of the liquid collecting box is partially increased without increasing the thickness of the liquid collecting box as a whole. After the connecting rod and the liquid collecting box are connected, turn the shielding sleeve to make the sealing ring fit tightly with the bottom of the liquid collecting box, so that the screws are hidden in the shielding sleeve to prevent the pickling liquid from corroding the screws.
