Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, in particular to a double-row tapered roller bearing processing device. Background Art

[0002] Double row tapered roller bearings are a type of bearing that can withstand radial and axial loads in both directions. It consists of an inner ring, an outer ring, rollers and a cage. The rollers are conical, which enables them to withstand radial and axial loads while rolling on the inner and outer ring conical surfaces. Double row tapered roller bearings are usually used in heavy-duty applications, such as automotive wheels, transmission systems and large mechanical equipment. Its double row structure provides higher load capacity and durability, so it is widely used in occasions that require complex loads.

[0003] The existing patent application number is: CN202222509310.9, and the patent name is: A utility model patent for a processing device for a tapered roller bearing. The scheme sets a rotating shaft, a transmission wheel, a half gear, a tooth plate and an arc-shaped clamping block, so that one of the rotating shafts can drive the other rotating shaft to rotate in the opposite direction through the engagement of two transmission wheels, so that the two rotating shafts respectively engage with the half gear and the tooth plate to prompt the two tooth plates to use the elastic force of the first spring to approach each other, so that the two connecting rods respectively drive the arc-shaped clamping blocks to approach each other to clamp the tapered roller bearing.

[0004] Although the above-mentioned device can quickly clamp and fix tapered roller bearings, when the product is in use, the grooves on the surface of the workbench make it easy for dust generated during the processing of the product to fall into its interior and surface, which may affect the meshing accuracy of the half gear and cause pollution to the processing environment; moreover, the device achieves fixing by clamping the limit rod into the corresponding second through hole. This type of fixing method is cumbersome to operate and requires precise alignment of the through hole, resulting in low work efficiency. The limit rod is prone to loosening, affecting the stability and work efficiency of the processing device, and needs to be improved. Utility Model Content

[0044] In this embodiment: when in use, the double-row tapered roller bearing to be processed is placed on the processing machine 103, and then the pull handle 203 is held by hand, and the rack slide bar 202 is pulled outward, so that the bottom of the rack slide bar 202 is engaged with the transmission gear 201, thereby driving the transmission gear 201 to rotate, and the transmission gear 201 drives the bidirectional screw 104 to rotate. The bidirectional screw 104 is connected to the moving slide 102 on both sides through mechanical transmission, so that it drives the clamping plates 101 to gradually approach each other, thereby clamping the outer wall of the material, and at the same time, drives the dust baffle 501 to move synchronously, thereby covering the top of the moving slide groove, to prevent dust chips from falling into the processing machine 103 during later processing.

[0045] When the rack slide 202 has completed its movement, the connecting slide 303, under the action of the connecting spring 304, pushes the first buckle 3011 to move toward the outside of the rack slide 202, and the first buckle 3011 drives the meshing gear 302 to rotate, and the other side of the meshing gear 302 drives the second buckle 3012 to move toward the outside of the rack slide 202, and the pulling handle 203 is released, so that the first buckle 3011 and the second buckle 3012 are close to the side wall of the processing machine 103 away from the pulling handle 203, preventing the rack slide 202 from retracting.

[0046] By turning on the power of the grinder 400 , the grinder 400 grinds the end surface of the double-row tapered roller bearing, and performs processing operations step by step according to processing requirements.

[0047] After the processing is completed, the operator presses the connecting rod buckle 3013 downward with his fingers, so that the connecting rod buckle 3013 drives the first buckle 3011 to move toward the inner side of the rack slide bar 202 through the connecting slide bar 303, and the first buckle 3011 drives the meshing gear 302 to rotate in the opposite direction, and the other side of the meshing gear 302 drives the second buckle 3012 to move toward the inner side of the rack slide bar 202, so that the rack slide bar 202 retracts into the pull-out slide groove under the action of the reset spring 204, and then drives the transmission gear 201 to rotate in the opposite direction, so that the transmission gear 201 drives the clamping clamps 101 to move away from each other in the opposite direction.

[0048] When the clamping plates 101 move away from each other, the dust baffle 501 is driven to move synchronously. When the dust baffle 501 moves backward, its upper surface contacts the fixed cleaning brush 502 at its top, thereby pushing the dust on its upper surface into the dust collecting box 503 at the front end thereof. At the same time, the dust baffle 501 drives the fixed cleaning brushes 502 on both sides to move on the processing machine 103, cleans the surface of the processing machine 103, and then pushes the dust into the dust collecting box 503 at the front end of the processing machine 103, thereby achieving the purpose of cleaning the processing machine 103, maintaining the cleanliness of the processing environment, and improving work efficiency.

[0049] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
