Description

TECHNICAL FIELD

[0001] The present application relates to the field of forging processing technology, in particular to a forging scale treatment equipment. BACKGROUND

[0002] Oil groove shaft sleeve is a key force-bearing component in mechanical transmission system, mainly used for supporting the rotating shaft of various motors, machine tools and engineering machinery. Through internal oil groove, it realizes lubricating oil storage and circulation, reduces friction loss during rotating shaft operation, and guarantees long-term stable operation of equipment. After being formed by forging process, the surface of the shaft sleeve will form a dense oxide scale, and the inner and outer walls are distributed with 3 groups of annular oil grooves. The groove structure is deep and the corners are regular, and the oxide scale is easy to remain in the groove and at the groove wall junction. The existing polishing technology mainly adopts manual sanding or single-station mechanical polishing mode. Manual polishing requires operators to adjust the polishing angle based on experience, and the inner and outer walls and oil grooves of the shaft sleeve are processed one by one. Mechanical polishing completes the polishing of the outer wall, inner wall and groove in batches by a single polishing head through a fixed clamp. Some devices need manual assistance to switch the polishing station and adjust the position of the polishing head.

[0003] The existing polishing technology has obvious limitations. First, manual polishing is extremely low in efficiency, takes a long time to process a single piece, and the polishing force and angle are uneven, which can easily lead to size deviation of the oil groove or inconsistency of the surface roughness. Although mechanical polishing improves efficiency, the inner and outer walls and oil grooves need to be processed in batches, which consumes time in process connection and cannot achieve synchronous polishing. In addition, the existing equipment generally lacks targeted debris cleaning design, and the oxide scale debris generated during polishing is easy to accumulate in the oil groove, which not only affects the subsequent polishing accuracy, but also requires additional cleaning procedures, further prolonging the processing cycle and failing to meet the high-efficiency and precision requirements in batch production.

[0024] Place the oil groove bushing on the machining base 22, start the motor 21 to make the three machining bases 22 rotate counterclockwise synchronously through the sprocket and chain, so that the limit block 23 and clamping block 24 on each machining base 22 move synchronously towards the middle to clamp the oil groove bushing. After clamping, the machining base 22 can continue to rotate, driving the three oil groove bushings to rotate together.

[0033] Further, when the fixing seat 33 is lowered, the guide rod 59 will slide on the surface of the guide seat 52, so as to be pushed by the protrusions on the surface of the guide seat 52 to be close to the groove on the inner surface of the oil groove shaft sleeve, and simultaneously, when the grinding device two 54 moves, the grinding device two 54 on the other side is driven to move in the opposite direction through the meshing of the rack one 57 and the gear one 56, so that the grinding device two 54 on the right side is attached to the groove on the outer surface of the oil groove shaft sleeve, thereby realizing the effect of grinding the inner and outer grooves at the same time, completely removing the residual oxide scale and impurities in the groove, realizing the synchronous and accurate grinding of the inner and outer oil grooves, and solving the problem that the oil groove part is difficult to be considered and blind area is easy to appear in the traditional equipment.

[0034] In the process that the grinding device two 54 is attached to the groove and separated from the groove, the outer area of the groove is contacted first, and then the movement track of the grinding device two 54 is embedded in the groove body, so that the oxide scale around the groove can be removed in advance before the groove is grinded, the impurities in the groove are prevented from being pressed and embedded in the groove wall during the subsequent grinding in the groove, the grinding environment in the groove body is ensured to be clean, and the thoroughness of removing the oxide scale on the groove wall is improved.

[0036] In the operation process of the embodiment, through the cooperation of the limiting mechanism 2, the lifting mechanism 3, the grinding assembly one 4 and the grinding assembly two 5, the inner and outer surfaces of the oil groove shaft sleeve are grinded at the same time, and the synchronous grinding of the inner and outer oil grooves is realized, the grinding device two 54 is embedded in the groove body under the action of the guide seat 52 for targeted grinding, the residual oxide scale in the groove part is avoided, the problem that the oil groove part is difficult to be considered and blind area is easy to appear in the traditional equipment is solved, the consistency of the grinding precision of the inner and outer oil grooves is ensured, and the overall quality qualification rate and the machining efficiency of the workpiece are improved. Figure 3 , Figure 7 、 Figure 8 With Figure 9 , the cleaning assembly 6 comprises a connecting block 61 fixedly connected to the rear side of the connecting seat 32, the lower end of the connecting block 61 is provided with an engagement transmission group 62, the upper end of the workbench 1 is fixedly connected with a supporting block 63 supporting the engagement transmission group 62, the side away from the connecting block 61 of the engagement transmission group 62 is fixedly connected with a pressing plate 64, the inner surface of the through hole 11 is provided with an air bag 65, and the lower end of the pressing plate 64 is fixedly connected with the air bag 65 on the same side.

[0037] The engagement transmission group 62 in the above comprises two rack twos and a gear two, wherein the two rack twos are centrally symmetrically located on the two sides of the gear two, one side is lowered while the other side is raised, and the supporting block 63 is used for limiting the gear two in the engagement transmission group 62.

[0038] Further, the surface of the air pipe 66 is provided with two one-way valves, one of which is located at the connection between the air pipe 66 and the air bag 65, and can only inhale inwardly, but cannot blow air; the other is located at the rear side of the air bag 65, and can only exhaust outwardly, but cannot inhale.

[0039] The front end of the air bag 65 is provided with two air pipes 66, and the bottom wall of the inner surface of the workbench 1 and located at the left and right sides of the front end of the air bag 65 are fixedly connected with collecting boxes 67, the front ends of the two collecting boxes 67 are rotatably connected with rotating shafts 68, and the front ends of the two rotating shafts 68 are fixedly connected with air inlets 69.

[0040] Further, in the descending process of the fixed seat 33, the rear side of the meshing transmission group 62 will be engaged, thereby driving the pressing plate 64 to pull the air bag 65 to become larger, so that the internal air pressure becomes smaller, thereby transmitting the suction force to the air inlet 69 through the air pipe 66, so that the air inlet 69 adsorbs the debris generated during polishing, wherein the connection between the air pipe 66 and the air inlet 69 is provided with a filter screen, so that the debris can directly enter the collecting box 67 for storage.
