Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing outer ring grinding technology, specifically a spherical grinding device for the outer ring of a spherical self-aligning bearing. Background Technology
[0002] The specific manufacturing process of bearings is as follows: raw materials – inner and outer ring machining, steel ball or roller machining, cage (stamping or solid) machining – bearing assembly – finished bearing. The machining of the inner and outer rings typically includes the following process: bar stock – forging – turning – heat treatment – grinding – ultra-precision machining – final inspection – rust prevention and warehousing. Among these, the bearing rings, after heat treatment, require grinding, which is a crucial step in ensuring bearing precision. After grinding, the production process of the bearing rings is essentially complete.
[0003] The existing method for machining the outer ring of a magnetic bearing involves applying an electric current and using magnetism to attract and fix it onto a template, allowing it to rotate with the template to achieve grinding of the bearing's raceway. However, for some bearing outer rings made of non-magnetic materials such as stainless steel, the lack of magnetism prevents them from being attracted and fixed to the template and rotated. Operators need to fix the bearing with fasteners before machining can proceed. Therefore, this method needs to be improved.
[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing grinding equipment. Utility Model Content
[0005] The purpose of this invention is to provide a spherical grinding device for the outer ring of a spherical self-aligning bearing, in order to solve the problem mentioned in the background art. The existing processing of the outer ring of a magnetic bearing relies on the magnetic attraction and fixation of the bearing to a template after being energized, so that it rotates with the template to achieve the grinding of the bearing outer ring raceway. However, for some bearing outer rings made of non-magnetic materials such as stainless steel, since they are not magnetic, they cannot be attracted and fixed together with the template and rotated. The operator needs to fix the bearing with a fixing component before processing can be carried out. Therefore, this invention needs to be improved.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a spherical grinding device for the outer ring of a spherical self-aligning bearing, comprising a table, a vertical plate fixed to the upper surface of the table, a support plate fixed to the surface of the vertical plate, a collecting dish above the support plate, magnetic plates fixed to the bottom of the collecting dish and the upper surface of the support plate, a servo motor mounted on the back of the vertical plate, a positioning post mounted at the output end of the servo motor, a limit plate mounted on the surface of the positioning post, a locking post mounted at the end of the positioning post away from the servo motor, a locking plate mounted on the locking post, an adjustment groove provided on the vertical plate, an adjustment rod provided in the adjustment groove, an adjustment block mounted on the adjustment rod, an mounting plate fixed on the adjustment block, and a grinding block and a cutting tool respectively mounted on the mounting plate.
[0007] Preferably, the collecting dish is magnetically connected to the support plate via a magnetic plate.
[0008] Preferably, the locking post has threads on its surface, and the locking post and the locking plate are connected by a through thread.
[0009] Preferably, the adjusting rod and the vertical plate are rotatably connected, and the adjusting rod and the adjusting block are connected by a through thread.
[0010] Preferably, the adjusting block is slidably connected to the vertical plate via an adjusting groove.
[0011] Preferably, both the grinding block and the cutting blade are connected to the mounting plate by bolts.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In this spherical self-aligning bearing outer ring spherical grinding device, the bearing outer ring is sleeved on the positioning post, and then the locking plate is screwed on the locking post. This facilitates the cooperation between the locking plate and the limiting plate to stably clamp the bearing outer ring, thereby making it convenient for the servo motor to drive the bearing outer ring to rotate synchronously. Twisting the adjusting rod to rotate can push the adjusting block through the thread to drive the mounting plate to move, which is beneficial for the mounting plate to drive the grinding block or cutting tool to move closer to the bearing outer ring, thus facilitating the grinding of the bearing outer ring surface.

[0020] The collecting dish 4 is magnetically connected to the support plate 3 via the magnetic plate 5, which makes it easy for the collecting dish 4 to be magnetically installed or removed from the support plate 3 via the magnetic plate 5.
[0021] The locking pin 9 has threads on its surface, and the locking pin 9 and the locking plate 10 are connected by a through thread, which makes it easier to tighten the locking plate 10 onto the locking pin 9 by screwing it on.
[0022] The adjusting rod 12 is rotatably connected to the vertical plate 2, and the adjusting rod 12 is threadedly connected to the adjusting block 13.

Then, the adjusting rod 12 is turned to rotate on the vertical plate 2. The adjusting rod 12 can push the adjusting block 13 through the thread to drive the mounting plate 14 to move. This is beneficial for the mounting plate 14 to drive the grinding block 15 or the cutting tool 16 to move closer to the bearing outer ring, thereby facilitating the grinding of the bearing outer ring surface.
