Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of slewing bearing processing, and in particular to a rough machining device for the end face of a slewing bearing. Background Technology
[0002] Roughing of the end face of a slewing bearing (usually referring to a large raceway ring) refers to the process of rapidly and extensively removing metal from the end face of a blank (such as a forging, casting, or welded part) before finishing.
[0003] This process is typically performed on a large vertical lathe or milling-turning center. The workpiece is fixed on a rotary table, and the excess material is efficiently removed by face turning or milling, producing high-strength, high-toughness spiral or sheet-like metal chips.
[0004] During rough machining, the splashed chips continuously accumulate on the rotary table. Some chips slide down the edge of the rotary table to the chip discharge chute at the bottom of the equipment. Once they enter the chute, the chips may become entangled in the screw threads or jammed in the clearance of the screw and nut assembly, hindering the normal rotation of the screw, causing transmission jamming and increasing operating resistance. Utility Model Content

[0022] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.
[0023] The rough machining device for the end face of the slewing bearing according to an embodiment of the present invention will be described below with reference to the accompanying drawings.
[0024] like Figures 1 to 5 As shown, the rough machining device for the end face of the slewing bearing of this utility model embodiment may include a machining table 1, a rotary table 2, multiple limiting components 3, multiple sets of guiding components 4, and a cutting mechanism 5.
[0025] The rotary table 2 is rotatably positioned above the processing table 1, and the upper surface of the rotary table 2 is provided with a first groove 21 and a plurality of second grooves 22, with a transmission component 6 provided in the first groove 21.
[0026] It should be noted that the rotary table 2 is connected to the motor (the motor is located inside the machining table 1). The rotary table 2 is driven to rotate by the motor, which in turn drives the slewing bearing to rotate. A pad is provided on the rotary table 2 to raise the slewing bearing and prevent the cutting tool 53 from damaging the rotary table 2 during machining.
[0027] Furthermore, the first groove 21 is located at the center of the rotating table 2, and a plurality of second grooves 22 are arranged in a circular array. A cover plate is provided on the first groove 21 to shield the first groove 21 and prevent waste from entering the first groove 21.
[0028] Multiple limiting components 3 are respectively disposed in the corresponding second grooves 22 and are respectively connected to the transmission component 6. Multiple sets of guide components 4 are respectively disposed in pairs in the corresponding second grooves 22 and are located on both sides of the limiting components 3.
[0029] It should be noted that the transmission component 6 can synchronously control the limiting component 3 to limit the slewing bearing, preventing the slewing bearing from shifting during the cutting process.
[0030] Furthermore, each second groove 22 is provided with two guide components 4. The guide components 4 can guide the waste debris falling into the second groove 22 to both sides, so as to prevent the waste debris from falling into the bottom of the second groove 22 and affecting the limiting effect of the limiting component 3.
[0031] The two opposite first inner walls of the second groove 22 are respectively provided with guide grooves 23, which are connected to the second groove 22, and a collection box 7 is provided inside the guide groove 23.
[0032] It should be noted that multiple collection boxes 7 are provided in pairs and are respectively located on both sides of the second groove 22. After being guided by the guide component 4, the waste debris slides into the collection box 7.
[0033] Furthermore, the collection box 7 can be fixed to the rotating platform with bolts to facilitate its tilting, and a handle is provided at the end of the collection box 7 for easy picking up and putting down of the collection box 7.
[0034] The upper surface of the processing table 1 is provided with a support plate 8, and a first slide module 9 is provided on the support plate 8. A cutting mechanism 5 is provided on the slide of the first slide module 9.
[0035] It should be noted that the first slide module 9 is vertically mounted on the support plate 8 to adjust the height of the cutting mechanism 5.
[0036] Furthermore, the cutting mechanism 5 includes a horizontal plate 51, a second slide module 52, and a cutting blade 53. The horizontal plate 51 is connected to the slide of the first slide module 9. The second slide module 52 is disposed on the lower surface of the horizontal plate 51. The cutting blade 53 is disposed on the slide of the second slide module 52. The second slide module 52 can adjust the position of the cutting blade 53 to accommodate various specifications of slewing bearings.
[0037] In one embodiment of this utility model, such as Figure 2 As shown, the limiting component 3 includes a lead screw 31, a slider 32, and a limiting plate 33. The lead screw 31 is rotatably disposed in the second groove 22; the slider 32 is threadedly connected to the lead screw 31 and slidably connected to the second groove 22; the limiting plate 33 is disposed on the slider 32.
[0038] It should be noted that the limiting plate 33 is located above the rotary table 2. When the lead screw 31 rotates, it can drive the slider 32 and the limiting plate 33 to move centrifugally or centrifugally, thereby limiting the movement from the inside or outside of the slewing bearing.
[0039] Furthermore, such as Figure 2 As shown, the transmission assembly 6 includes a first bevel gear 61 and a plurality of second bevel gears 62, wherein the first bevel gear 61 is rotatably disposed in the first groove 21; the plurality of second bevel gears 62 are respectively disposed on the corresponding lead screw 31, and the second bevel gears 62 are meshed with the first bevel gear 61.
[0040] It should be noted that the first bevel gear 61 of this utility model is connected to the motor, which can drive the first bevel gear 61 to rotate, and through the cooperation of the second bevel gear 62, drive the lead screw 31 to rotate.
[0041] In one embodiment of this utility model, such as Figure 2 As shown, the guide assembly 4 includes a spring 41 and a guide plate 42, wherein a third groove 24 is provided on the two opposing second inner walls of the second groove 22, and the two ends of the spring 41 are respectively connected to the inner wall of the third groove 24 and the guide plate 42.
[0042] The guide plate 42 is slidably disposed in the second groove 22, and the end of the guide plate 42 away from the spring 41 abuts against the side wall of the slider 32.
[0043] It should be noted that the third groove 24 is connected to the second groove 22. One end of the guide plate 42 is slidably disposed in the third groove 24, and the lower surface of the guide plate 42 is larger than the width of the second groove 22, so as to block the second groove 22 and prevent waste from entering the bottom of the second groove 22.
[0044] Furthermore, when the slider 32 moves, the guide plate 42 moves under the action of the spring 41, thereby ensuring that the guide plate 42 always abuts against the side wall of the slider 32.
[0045] Furthermore, such as Figure 3 As shown, the cross-section of the guide plate 42 is triangular, and the two edges of the guide plate 42 extend into the guide groove 23.
[0046] It should be noted that the two inclined surfaces of the triangular structure can guide the waste, preventing it from accumulating on the guide plate 42, and quickly guiding the waste into the two collection boxes 7 for convenient unified collection.
[0047] Specifically, the relevant personnel place the slewing bearing on the pad and control the transmission assembly 6 to start. With the cooperation of the first bevel gear 61 and the second bevel gear 62, multiple lead screws 31 are driven to rotate synchronously, thereby causing multiple sliders 32 to move towards the center of the rotary table 2, and finally the slewing bearing is limited by the limiting plate 33.
[0048] Then, the first slide module 9 and the second slide module 52 can be started to adjust the position of the cutting tool 53 so that the cutting tool 53 abuts against the upper surface of the rotary table 2, and the rotary table 2 is controlled to rotate to realize the machining of the end face of the slewing bearing.
[0049] The waste chips generated during processing slide down the inclined surface of the guide plate 42 to the guide groove 23, and finally fall into the collection box 7 for unified collection. This effectively prevents the chips from entering the bottom of the second groove 22 and interfering with the rotation of the lead screw 31, and also facilitates the subsequent centralized processing of the chips.
[0050] In summary, the slewing bearing end face roughing device of this utility model embodiment has a transmission component that can simultaneously control multiple limiting components to limit the slewing bearing; at the same time, the inclined surface of the guide plate guides the waste chips into the collection box for unified collection, avoiding affecting the operation of the lead screw and thus protecting the lead screw.
