Description

Technical Field

[0001] The utility model relates to the technical field of bearing grinding, in particular to a clamping structure of a bearing grinding machine. Background Art

[0002] Bearings are one of the most important and common components in mechanical equipment. They are mainly used to support mechanical rotating bodies and reduce the friction coefficient during their movement.

[0003] At present, in the production of bearings, it is necessary to grind the inner ring wall or the outer ring wall of the bearing outer ring (or inner ring) to ensure that the bearing can better support mechanical rotation. Therefore, it is necessary to use a bearing grinder to grind the outer ring or the inner ring of the bearing. However, the existing grinder can only grind the outer ring or the inner ring of the bearing, and it is impossible to achieve continuous grinding of the inner ring and the outer ring on the same device, so the work efficiency is not high.

[0004] However, when grinding the outer ring or inner ring of the bearing, it is mainly the cooperation of the clamping structure and the grinding structure of the bearing grinder. Therefore, it is necessary to improve both of them so that they can be used on one grinder to complete the grinding of the outer ring and inner ring of the bearing. Utility Model Content

[0120] The seat body 300 has a threaded hole;

[0121] A dovetail mounting groove is formed on the base body 300 and is used for mounting the mold;

[0122] A positioning cavity 301 is formed at the bottom of the dovetail mounting groove;

[0123] A positioning post 302 is telescopically disposed in the positioning cavity 301 and partially exposed from the cavity opening of the positioning cavity 301. A magnet 302a is disposed at the bottom of the positioning post 302. In other embodiments, a spring 302d may be further disposed between the positioning cavity 301 and the positioning post 302.

[0124] The first electromagnet 303 is mounted on the base 300 and generates magnetism when powered on and is used to control the positioning post 302 to move away from the first electromagnet 303, that is, the magnetic pole generated by the first electromagnet 303 when powered on is opposite to the magnet 302a, so the positioning post can be driven to extend out of the positioning cavity;

Generally, at least two grinding tools are installed in this embodiment to grind the outer wall of the bearing and the inner ring of the bearing, that is, the grinding end of the grinding tool is at different heights from the mounting seat, so that different grinding tools can contact the outer wall or inner ring of the bearing when entering the grinding area.

[0132] In this embodiment, a chamber 60 capable of communicating with the dust collecting body and the dust inlet chamber is formed in the base body 5a of the grinding tool 5.

[0167] In addition, the utility model also provides a method for using the bearing grinder, comprising the following steps:

[0168] S1 installation tool: install at least two types of abrasive tools on the mounting seat, and fix the mounting seat to the second sliding seat by bolts;

[0169] S2 Loading: Load the bearing parts to be polished into the storage cavity

[0170] S3 loading: the second cylinder controls the material receiving body to rotate and connect the material receiving chamber with the material storage chamber. After the bearing part enters the material receiving chamber from the material storage chamber, the second cylinder controls the material receiving body to reset and close the material storage chamber. Under the control of the first cylinder and the second electromagnet is powered on, the first sliding shaft moves toward the material receiving chamber and passes through the bearing part. The second electromagnet is then powered off and the bearing part is fixed by the first clamping block to complete the loading.

[0171] S4 grinding: after the second cylinder controls the receiving body to move away from the grinding area, the first sliding structure and the second sliding structure control the grinding end of any grinding tool to contact the outer wall of the bearing part, and when the third motor drives the first sliding shaft to rotate, the outer wall of the bearing part is ground;

[0172] After the outer wall grinding is completed, in a mode where the first electromagnet remains energized and the second electromagnet remains de-energized, the second cylinder controls the first sliding shaft to leave the grinding area and moves the second sliding shaft toward the grinding area. When the bearing part enters the clamping groove of the second sliding shaft, the first electromagnet is de-energized and the second electromagnet is energized, and the bearing part on the first sliding shaft is transferred to the second sliding shaft. Under the control of the first sliding structure and the second sliding structure, the grinding end of the other grinding tool contacts the inner wall of the bearing part, thereby completing the grinding of the inner wall of the bearing part.

[0173] S5 unloading: After the grinding is completed, the first electromagnet is energized, and the bearing parts in the clamping groove fall out of the clamping groove, completing the unloading.

[0174] refer to Figure 8-13 , the principle of this embodiment is:

[0175] Loading principle (i.e. unloading principle of storage body): the bearing parts to be polished are placed in the storage chamber, refer to Figure 8 and Fig.13 When discharging, the second cylinder controls the piston shaft to rise and controls the driving shaft to rotate, and then makes the material receiving body rotate counterclockwise with the driving shaft as the standard until the material receiving chamber is aligned with the discharging end, and the bearing component in the material storage chamber can enter the material receiving chamber, and the material receiving body continues to rotate counterclockwise so that the insertion hole on the material receiving chamber is coaxially aligned with the first sliding shaft. When the second electromagnet is energized, the first sliding shaft is controlled by the first cylinder to enter the insertion hole, and the bearing component is sleeved on the first sliding shaft. Then the second electromagnet is powered off, and the first clamping fast is reset by the first clamping spring, and the bearing is fixed from the inner ring of the bearing component. Then, the first sliding shaft is continued to be controlled to move in the direction of the grinder (grinding structure), and the first sliding structure and the second sliding structure are coordinated to make the outer ring of the bearing component contact with the grinder. When the third motor is rotating, the outer ring wall of the bearing component is grinded by the grinder.

[0176] Transfer clamping principle: After the outer ring wall of the bearing component is polished, the first cylinder controls the first sliding shaft to retract into the chassis, and the second sliding shaft gradually leaves the chassis. When the bearing component enters the clamping groove of the second sliding shaft, the second electromagnet is energized, the third electromagnet is de-energized, and the bearing component is fixed in the second sliding shaft through the second clamping block, and the second sliding shaft is extended out of the chassis, and the first sliding structure and the second sliding structure are coordinated to make the inner ring of the bearing component contact with another grinding tool. When the third motor rotates, the second sliding shaft is driven to rotate by the first sliding shaft through the cooperation of the limiting rib and the limiting groove, thereby completing the large module of the inner ring wall of the bearing component;

[0177] Unloading principle: After grinding is completed, the third electromagnet is energized, the bearing component loses the fixation of the second clamping block and falls into the unloading chute, completing the unloading.

[0178] Worthy of mention are:

[0179] In this embodiment, the material receiving body can first be controlled by the second cylinder so that the material receiving body closes the discharge end.
