Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, in particular to a cooling device for bearing grinding machine processing. Background Art

[0002] During the precision machining of the bearing inner ring by the grinder, a large amount of heat energy is generated due to the intense friction between the grinding head and the bearing inner ring. If this heat is not dissipated in time, it will accumulate to form a local high-temperature area, which will cause thermal damage to the workpiece surface, seriously weakening the machining accuracy and overall quality of the bearing inner ring.

[0003] Chinese patent CN115091276 B discloses a cooling system, which includes a drive mechanism and a conveying mechanism. The drive mechanism is used to drive the movable plate to move circumferentially along the grinding mechanism. When the conveying box rotates with the system to the bottom position or one side of the gear ring, there is a significant design limitation: the liquid outlet pipe is located exactly in the top area or side of the conveying box. This layout directly prevents the coolant from flowing smoothly out of the liquid outlet pipe and being delivered to the cooling nozzle, thereby interrupting the effective cooling process of the bearing inner ring, and ultimately affecting the overall cooling efficiency and processing quality of the bearing.

[0007] Furthermore, the telescopic mechanism includes an outer tube, an inner rod and an adjusting knob. The outer tube is fixedly connected to the sliding seat, the inner rod is slidably fitted inside the outer tube, and the adjusting knob is threadedly connected to the outer tube.

DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0015] like Figure 1As shown, a cooling device for a bearing grinding machine is installed on a grinding machine and includes a gear ring 1. The gear ring is fixedly connected to the grinding machine. The design of the gear ring allows the entire cooling device to be firmly connected to the grinding machine, providing a foundation for subsequent sliding and rotation. The gear ring is slidably matched with a sliding seat 3. The design of the sliding seat allows the coolant tank to move on the grinding machine, covering a wider grinding area. A drive motor 4 is installed on the sliding seat. The output shaft of the drive motor is connected to a gear 2. The gear is meshed with the gear ring. The meshing design of the gear and the gear ring enables the sliding seat to rotate smoothly on the gear ring, thereby driving the coolant tank to evenly spray coolant.

[0016] A telescopic mechanism is provided directly above the sliding seat for adjusting the height of the coolant tank. The design of the telescopic mechanism allows the cooling nozzle to be flexibly adjusted according to the height and grinding requirements of different bearings, thereby improving the cooling effect. A rotating shaft 10 is provided at the top of the telescopic mechanism, on which a coolant tank 11 is rotatably connected. The coolant tank is provided with a liquid outlet pipe 12, which is connected to a delivery pipe 14. A liquid outlet pump 13 is provided at the liquid outlet pipe to provide power for the delivery of the coolant. The design of the liquid outlet pump ensures stable output of coolant and ensures the cooling effect. The delivery pipe is connected to a cooling nozzle 20.

[0017] In at least one embodiment, the telescopic mechanism includes an outer tube 7, an inner rod 9, and an adjustment knob 8. The outer tube is fixedly connected to the sliding seat, and the inner rod slides within the outer tube. The adjustment knob is threadedly connected to the outer tube. The adjustment knob enables the inner rod to move along the inner wall of the outer tube and position it at a point on the outer tube. This design allows the operator to easily adjust the position of the inner rod by rotating the adjustment knob, thereby achieving precise control of the coolant tank height.

[0018] In at least one embodiment, a support mechanism is provided at the bottom of the coolant tank, and a cooling nozzle is installed at the end of the support mechanism.

[0019] Furthermore, the support mechanism includes a support block 15, a through hole is formed in the middle of the support block, a screw 18 is slidably fitted in the through hole, the end of the screw is rotatably connected to a clamp 19, and a cooling nozzle is installed in the clamp.

[0020] Furthermore, the screw is mounted with a left fastening nut 17 and a right fastening nut 16, which are located on either side of the support block. The design of the left and right fastening nuts allows the operator to easily adjust the position and angle of the cooling nozzle by tightening or loosening the nuts, improving the convenience and accuracy of adjustment.

[0021] Working method: Fix the cooling device to the table of the grinding machine through the ring gear, and ensure that the ring gear is firmly installed on the table with bolts. Slide the sliding seat onto the ring gear and install the drive motor on the sliding seat. Adjust the gear on the output shaft of the drive motor so that it meshes correctly with the ring gear. Install the telescopic mechanism directly above the sliding seat, including the outer tube, inner rod and adjustment knob. Adjust the position of the inner rod in the outer tube by rotating the adjustment knob to determine the height of the telescopic mechanism. Install the rotating shaft on the top of the telescopic mechanism and rotate it on the rotating shaft to connect the coolant tank. Install the outlet pipe on the coolant tank and connect the delivery pipe and the cooling nozzle. Ensure that the outlet pump is working properly to transport the coolant from the coolant tank to the cooling nozzle.

[0022] Install the support mechanism, including the support block and screw, at the bottom of the coolant tank. Adjust the position and angle of the cooling nozzle by adjusting the left and right fastening nuts on the screw.

[0023] Turn on the power of the drive motor to rotate the gear on the ring gear, thereby driving the sliding seat and coolant tank to move around the grinding car. As needed, adjust the height of the telescopic mechanism by turning the adjustment knob to ensure that the cooling nozzle is in the optimal position.

[0024] The discharge pump is activated to deliver coolant from the coolant tank through the discharge pipe and delivery pipe to the cooling nozzle. The cooling nozzle sprays the coolant on the bearing grinding area to reduce temperature and thermal deformation. During the process, the bearing temperature and grinding results are continuously monitored. The height of the telescopic mechanism, the speed of the drive motor, and the coolant flow rate and spray angle are adjusted as needed.

[0025] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
