Description

Technical Field

[0001] The utility model relates to the technical field of bearing outer ring processing, in particular to a surface polishing device for bearing outer ring processing. Background Technique

[0002] A bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. It consists of an inner ring, an outer ring, rolling elements, and a cage. The rolling elements transfer force and bear the load between the inner and outer rings to achieve the relative movement of mechanical components. During the automobile manufacturing process, bearings are widely used in key parts such as the transmission system, steering system, and suspension system, such as transmissions, final drives, and wheel bearings.

[0003] The bearing outer ring is made of high-carbon chromium steel, which generates burrs during the manufacturing process, and oxides will form on the surface during transportation and storage, thus affecting subsequent assembly and use. In addition, during the polishing process of the existing bearing outer ring, residues such as metal chips will be generated, and additional residue removal processes need to be added, increasing the production time and cost. Therefore, a surface polishing device for bearing outer ring processing is proposed to solve the above-mentioned problems. Content of the Utility Model

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. For this reason, the utility model proposes a surface polishing device for bearing outer ring processing, which includes a bracket and a processing platform arranged on the bracket. Two relatively arranged guardrails are fixedly installed on the processing platform, and a feeding channel for the bearing outer ring to pass through is formed between the two guardrails. One end of the feeding channel is provided with a pushing plate slidably connected to the processing platform. A feeding assembly cooperating with the pushing plate is arranged on the processing platform. A grinding mechanism is arranged on the side of the feeding assembly away from the pushing plate. A bent channel communicating with the feeding channel is arranged on the processing platform, and a cleaning assembly for removing residues on the surface of the bearing outer ring is arranged on the bent channel.

[0005] Further, the feeding assembly includes a transverse moving platform fixedly installed on the bracket. A longitudinal moving platform is arranged at the moving end of the transverse moving platform. An increasing block is fixedly installed at the moving end of the longitudinal moving platform. Two paddles are bolted to the surface of the increasing block.

[0006] Further, a limiting member is arranged on one side of the feeding assembly. The limiting member includes a one-way air cylinder fixedly installed on the bracket. A V-shaped clamping block is arranged at the telescopic end of the one-way air cylinder, and the height of one of the guardrails corresponds to the height of the V-shaped clamping block.

[0007] Further, the grinding mechanism includes a mounting frame which is arranged on the side of the feeding channel away from the limiting member. A telescopic cylinder is arranged on the mounting frame, and a first driving motor is arranged at the telescopic end of the telescopic cylinder. A second driving motor which is arranged opposite to the first driving motor is fixedly mounted on the bracket, and brushes are arranged at the output ends of the first driving motor and the second driving motor.

[0008] Further, the output end of the first driving motor is flange-connected with a fixing plate. A plurality of mounting holes are formed in the fixing plate, bolts are arranged in the mounting holes, and threaded holes adapted to the bolts are formed in the brushes.

[0009] Further, the cleaning assembly includes a wind hood with openings at both ends. The wind hood is arranged on the bent channel. A plurality of fans which are equidistantly distributed are arranged at the top of the wind hood. A chip discharging groove is formed in the processing platform below the wind hood. Two protective layers are arranged at the openings at both ends of the wind hood. Soft magnetic strips are arranged on the opposite sides of adjacent two protective layers, and the two soft magnetic strips adsorb each other.

[0010] The beneficial effects of the present utility model are as follows: By arranging the feeding assembly and cooperating with the pushing plate, the outer rings of the bearings can be pushed forward one by one along the feeding channel for feeding. A grinding device is also arranged, which can be flexibly adjusted according to the size and shape of the outer rings of the bearings to ensure the uniformity and consistency of the grinding effect. At the same time, the detachable design of the brushes facilitates replacement and maintenance. Finally, a cleaning assembly is arranged to blow the residues on the surfaces of the outer rings of the bearings away by the airflow generated by the fans and collect them through the chip discharging groove, effectively avoiding the influence of residues such as metal chips on the subsequent processing. Compared with the existing technology, this device integrates functions such as automatic feeding, grinding and cleaning, reduces manual intervention, improves production efficiency and processing accuracy, and realizes the full-process automation processing from the feeding of the outer rings of the bearings to the surface polishing and then to the cleaning of the residues.

[0018] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] In the embodiment, it consists of Figures 1-4Provided is a surface polishing device for processing the outer ring of a bearing, including a bracket 1 and a processing platform 2 arranged on the bracket 1. Two relatively arranged guardrails 3 are fixedly installed on the processing platform 2, and a feeding channel 4 for the outer ring of the bearing to pass through is formed between the two guardrails 3. One end of the feeding channel 4 is provided with a pushing plate 5 slidably connected to the processing platform 2. A feeding assembly 6 cooperating with the pushing plate 5 is arranged on the processing platform 2. A grinding mechanism 7 is arranged on the side of the feeding assembly 6 away from the pushing plate 5. A bent channel 8 communicating with the feeding channel 4 is arranged on the processing platform 2, and a cleaning assembly 9 for removing residues on the surface of the outer ring of the bearing is arranged on the bent channel 8. The outer ring of the bearing is placed at the entrance of the feeding channel 4 on the processing platform 2. The feeding channel 4 is formed by two relatively arranged guardrails 3 to ensure a stable path for the outer ring of the bearing during transmission. A hydraulic push rod is arranged on the bracket 1, and the pushing plate 5 is located at the telescopic end of the hydraulic push rod. Driven by the pushing plate 5, the outer ring of the bearing is moved towards the feeding assembly 6. The feeding assembly 6 moves the first outer ring of the bearing to the polishing position of the grinding mechanism 7, and at the same time moves the next outer ring of the bearing to the pre-feeding position. After the grinding mechanism 7 completes the polishing process, the feeding assembly 6 moves the outer ring of the bearing at the pre-feeding position to the grinding position, and at the same time pushes the outer ring of the bearing that has completed the processing forward. After grinding, the outer ring of the bearing continues to enter the cleaning assembly 9 along the bent channel 8 to remove possible grinding debris remaining on the surface of the outer ring of the bearing.

[0020] Refer to Figures 1-4 Among them, the feeding assembly 6 includes a transverse moving platform 61 fixedly installed on the bracket 1. A longitudinal moving platform 62 is arranged at the moving end of the transverse moving platform 61. An elevation block 63 is fixedly installed at the moving end of the longitudinal moving platform 62. Two paddles 64 are bolted to the surface of the elevation block 63;

[0021] Through the above structural settings, the structural principles of the transverse moving platform 61 and the longitudinal moving platform 62 are the same and are consistent with the working principle of the electric slide rail in the prior art, so they will not be repeated here. The longitudinal moving platforms 62 cooperate with each other, and the paddles 64 can accurately move to the position of the material, pick up or push the material to the designated position through physical contact, realizing the handling and positioning of the material.

[0022] Refer to Figures 1-4 Among them, it includes a limiting member 10 arranged on one side of the feeding assembly 6. The limiting member 10 includes a one-way cylinder 101 fixedly installed on the bracket 1. A V-shaped clamping block 102 is arranged at the telescopic end of the one-way cylinder 101, and the height of one of the guardrails 3 corresponds to the height of the V-shaped clamping block 102;

[0023] With the above structural arrangement, the telescopic end of the unidirectional cylinder 101 is connected to the V-shaped clamping block 102. When the outer ring of the bearing enters the grinding position, the V-shaped clamping block 102 approaches the outer ring of the bearing, and at the same time forms a squeezing force with the guardrail 3, thereby limiting and fixing the outer ring of the bearing to prevent the outer ring of the bearing from shifting during the grinding process.

[0024] Referring to Figures 1-4 , wherein, the grinding mechanism 7 includes a mounting frame 71, the mounting frame 71 is arranged on the side of the feeding channel 4 away from the limiting member 10, a telescopic cylinder 72 is arranged on the mounting frame 71, a first driving motor 73 is arranged at the telescopic end of the telescopic cylinder 72, a second driving motor 74 arranged opposite to the first driving motor 73 is fixedly installed on the bracket 1, and brushes 75 are arranged at the output ends of the first driving motor 73 and the second driving motor 74. Fixed disks are flange-connected to the output ends of the first driving motor 73 and the second driving motor 74, a plurality of mounting holes are formed in the fixed disks, bolts are arranged in the mounting holes, and threaded holes adapted to the bolts are formed in the brushes 75;

[0025] With the above structural arrangement, before grinding starts, by controlling the telescopic movement of the telescopic cylinder 72, the first driving motor 73 and the brush 75 mounted thereon are adjusted to a suitable position, and at the same time, it is ensured that the brush 75 on the second driving motor 74 is also in the correct position, so that the brushes on both sides can contact and grind the material simultaneously. Start the first driving motor 73 and the second driving motor 74, and the rotating brushes 75 on both sides will simultaneously contact the surface of the material for grinding and polishing operations. Since the two motors work synchronously and the brushes 75 are arranged oppositely, uniform grinding of the material surface can be achieved.

[0026] Referring to Figures 1-4 , wherein, the cleaning component 9 includes a wind hood 91 with both ends open, the wind hood 91 is arranged on the bent channel 8, a plurality of fans 92 evenly distributed at equal intervals are arranged at the top of the wind hood 91, and a chip discharge groove 93 located below the wind hood 91 is formed on the processing platform 2. Two protective layers 94 are arranged at both ends of the wind hood 91, soft magnetic strips 95 are arranged on the opposite sides of adjacent two protective layers 94, and the two soft magnetic strips 95 adsorb each other;

[0027] With the above structural arrangement, when the fans 92 are started, a strong wind force will be generated to drive the air to form a high-speed flowing air current inside the wind hood 91, which has a strong blowing ability and can blow the chips and waste generated during the processing away from the outer ring of the bearing. The arrangement of the protective layers 94 effectively prevents the chips and waste from directly flying out of the wind hood 91, protecting the safety of the surrounding environment and equipment. At the same time, the mutual adsorption of the soft magnetic strips 95 ensures the tight closure of the protective layers 94 and will not interfere with the entry of the outer ring of the bearing into the wind hood 91.

[0028] It should be noted that, in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the said element.

[0029] Although the embodiments of the present utility model have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model, and the scope of the present utility model is defined by the appended claims and their equivalents.
