Description

Technical Field

[0001] The invention relates to the technical field of parts processing, in particular to a grinding device for manufacturing mechanical parts. Background Art

[0002] Grinding of mechanical parts is a machining method that uses high-speed rotating grinding wheels and other abrasive tools to accurately remove excess material from the workpiece through grinding to obtain the required shape, size and surface accuracy. It is widely used in the machinery manufacturing industry and has the characteristics of high precision, high surface quality and wide applicability. In the process of machining the outer ring of the roller bearing, it is necessary to grind the inner wall of the outer ring to form a raceway to provide precise positioning for the roller. In the production process of roller bearings, grinding the inner wall of the outer ring is a crucial link. It is responsible for shaping the raceway of the load-bearing rollers. This raceway not only provides precise positioning for the rollers, but also The stability and durability of the bearing during operation are ensured. However, the currently widely used processing method relies on fixed-shape cutter heads for grinding, which is particularly inconvenient when facing different types of roller bearing outer rings. When different types of outer rings need to be processed, the operator has to interrupt the production process and replace the cutter head that matches the outer ring to be processed. The operation requires first removing the old cutter head, then replacing the matching cutter head and fixing it. The operation is extremely cumbersome. This step of frequently replacing the cutter head is not only time-consuming and labor-intensive, but also significantly reduces the overall production efficiency. For this reason, we propose a grinding device for manufacturing mechanical parts. Summary of the invention

[0031] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1-Figure 10 The present invention provides a technical solution: a grinding device for manufacturing mechanical parts, including a grinding machine body 1, a grinding head 2 and a clamping seat 3, wherein a plurality of grinding heads 2 are provided, and the plurality of grinding heads 2 are of different models, and further comprising a switching rod 4, wherein the switching rod 4 is located on the grinding machine body 1, and the plurality of switching rods 4 are provided. When the grinding machine body 1 switches to different models of bearing outer rings for grinding, the switching rod 4 is synchronously controlled to switch out a grinding head 2 adapted to the current bearing outer ring model.

[0033] The grinding assembly 5 is arranged on the grinding machine body 1 , and the grinding assembly 5 is used to drive the switching rod 4 to rotate, thereby pushing the grinding heads 2 of different models to grind the outer rings of bearings of different models.

[0034] The advantage of the setting of the grinding component 5 is that when the grinding machine body 1 switches to different types of bearing outer rings for grinding, the switching rod 4 can be synchronously controlled to quickly switch out the grinding head 2 that is suitable for the current bearing outer ring model without manual operation. The automatic switching of the grinding head 2 can significantly reduce the time required to replace the grinding head 2, thereby speeding up the production process and improving overall production efficiency. Manual switching of the grinding head 2 may cause errors due to improper operation or negligence, while automatic switching can ensure that the correct grinding head 2 can be switched accurately and quickly every time, reducing production problems caused by human errors. Automatic switching reduces the labor intensity of operators, allowing them to focus on other more important tasks, or reduces dependence on operators. Manual switching of the grinding head 2 may require contact with the inside of the machine or moving parts, which poses certain safety risks, while automatic switching can be completed without contacting the inside of the machine or moving parts, thereby improving the safety of operation.

[0035] The chamfering mechanism 9 is arranged on the grinding assembly 5. When the grinding assembly 5 is grinding the outer ring of the bearing, the chamfering mechanism 9 is synchronously controlled to chamfer the edges and corners of the grinding surface of the outer ring of the bearing.

[0036] The advantage of the chamfering mechanism 9 is that, while switching the grinding head 2, the chamfering tool 105 for chamfering the edges and corners can also be switched synchronously to adapt to edges and corners of different angles. Synchronous switching of the grinding head 2 and the chamfering tool 105 can significantly reduce the time required for tool replacement, making the entire processing process smoother and more efficient. There is no need to interrupt the operation to replace the tool during the processing, thereby improving the overall production efficiency. At the same time, for different types of bearing outer rings and different edge angles, selecting suitable grinding heads 2 and chamfering tools 105 can ensure processing accuracy and surface quality, and synchronous switching can avoid processing errors and surface defects caused by tool mismatch.

[0037] The grinding assembly 5 includes a grinding piece 6 arranged on the grinder body 1, and the grinding piece 6 is used to grind the outer rings of bearings of different models. The grinding piece 6 is provided with a switching piece 7. When the grinding machine body 1 is switched to different types of bearing outer rings for grinding by using the switching piece 7, the switching rod 4 is synchronously controlled to switch out a grinding head 2 suitable for the current bearing outer ring model. The switching piece 7 is provided with a driving piece 8, and the driving piece 8 is used to provide power for the switching piece 7 to work.

[0038] The grinding piece 6 includes a mounting bin 61 arranged on the grinder body 1, a rotating shaft 62 is rotatably arranged in the mounting bin 61, a rotating plate 63 is arranged on the rotating shaft 62, mounting tubes 64 are arranged at both ends of the rotating plate 63, the mounting tube 64 is slidably connected with the switching rod 4, a limit plate 65 is slidably arranged in the mounting tube 64, the limit plate 65 is connected with the switching rod 4, a return spring 66 is arranged on the limit plate 65, one end of the return spring 66 is connected to the mounting tube 64, a clamping block 67 is arranged on the switching rod 4, a power shaft 68 is arranged on the grinder body 1, the power shaft 68 passes through the mounting bin 61 and is movably connected with the mounting bin 61, and a clamping groove 69 used in conjunction with the clamping block 67 is arranged on the power shaft 68.

[0039] The switching member 7 includes a switching chamber 71 arranged on the mounting chamber 61, one end of the rotating shaft 62 extends into the switching chamber 71, the power shaft 68 passes through the switching chamber 71 and is movably connected with the switching chamber 71, a pneumatic chamber 72 is arranged in the switching chamber 71, a piston plate 73 is slidably arranged in the pneumatic chamber 72, a pushing rack 74 is arranged at one end of the piston plate 73, and a pushing gear 75 meshing with the pushing rack 74 is arranged at one end of the rotating shaft 62 located in the switching chamber 71, and the pushing gear 75 is connected to the rotating shaft 62 through a one-way bearing.

[0040] The advantage of the switching member 7 is that when the grinder body 1 switches to different types of bearing outer rings for grinding, the switching rod 4 can be synchronously controlled to quickly switch out the grinding head 2 that is suitable for the current bearing outer ring model without manual operation. The automatic switching of the grinding head 2 can significantly reduce the time required to replace the grinding head 2, thereby speeding up the production process and improving overall production efficiency. Manual switching of the grinding head 2 may cause errors due to improper operation or negligence, while automatic switching can ensure that it can accurately and quickly switch to the correct grinding head 2 every time, reducing production problems caused by human errors.

[0041] The driving member 8 includes a power airbag 81 arranged in the switching chamber 71, and an air guide tube 82 connected to the pneumatic chamber 72 is arranged on the power airbag 81. An extrusion spring 83 is arranged in the power airbag 81, and a bearing plate 84 is arranged on the extrusion spring 83. An extrusion plate 85 is rotatably arranged at one end of the power shaft 68 located in the switching chamber 71.

[0042] The advantage of the drive member 8 is that the grinding head 2 can be switched quickly without manual operation. Manual switching of the grinding head 2 may require contact with the inside of the machine or moving parts, which poses certain safety risks, while automatic switching can be completed without contacting the inside of the machine or moving parts, thereby improving the safety of operation.

[0043] When processing the outer ring of the bearing, first control the power shaft 68 to move and enter the installation chamber 61. The movement of the power shaft 68 is driven by a motor. This is a prior art, so it will not be described in detail here. When the power shaft 68 enters the installation chamber 61, the clamping groove 69 opened thereon engages with the clamping block 67. After the engagement is completed, the power shaft 68 continues to move, synchronously pushing the switching rod 4 and the grinding head 2 connected to the switching rod 4 to extend out of the installation chamber 61 to grind the outer ring of the bearing.

[0044] When there is no need to replace the grinding head 2, it is only necessary to control the overall movement of the grinding machine body 1. When the grinding head 2 needs to be switched, the power shaft 68 is controlled to retract. When the power shaft 68 retracts, it drives the extrusion plate 85 arranged thereon to move, and squeezes the power airbag 81, so that the gas in the power airbag 81 enters the pneumatic chamber 72 and pushes the piston plate 73 to move. The movement of the piston plate 73 drives the pushing rack 74 to move. The movement of the pushing rack 74 drives the pushing gear 75 engaged with it to rotate. The rotation of the pushing gear 75 drives the rotating shaft 62 to rotate. The rotation of the rotating shaft 62 drives the rotating plate 63 and the mounting tube 64 located on both sides of the rotating plate 63 to switch positions. At the same time, because the pushing gear 75 is connected to the rotating shaft 62 through a one-way bearing, the rotating shaft 63 will not be driven to rotate when the pushing rack 74 is reset.

[0045] The chamfering mechanism 9 includes a chamfering piece 10 arranged on the mounting bin 61, and the chamfering piece 10 is used to chamfer the corners of the bearing outer ring. A rotating piece 11 is arranged on the chamfering piece 10, and the rotating piece 11 is used to control the rotation and switching of the chamfering piece 10 to adapt to different types of bearing outer rings. A transmission piece 12 is arranged on the rotating piece 11, and the transmission piece 12 is used to drive the rotating piece 11 to work.

[0046] The chamfering part 10 includes a guide rail 101 arranged on the installation bin 61, a sliding plate 102 is slidably arranged in the guide rail 101, the sliding plate 102 is L-shaped, a rotating shaft 103 is rotatably arranged on the sliding plate 102, a damping connection is adopted between the rotating shaft 103 and the sliding plate 102, a deflection rod 104 is arranged on the rotating shaft 103, and chamfering grinding tools 105 with different angles are arranged at both ends of the deflection rod 104.

[0047] The rotating member 11 includes a rotating rack 111 arranged on the guide rail 101, a positioning shaft 112 is rotatably arranged on the sliding plate 102, a positioning gear 113 is arranged on the positioning shaft 112 and meshes with the rotating rack 111, the positioning gear 113 is connected to the positioning shaft 112 through a one-way bearing, a toothed pulley 114 is arranged on the positioning shaft 112 and the rotating shaft 103, and a toothed belt 115 is arranged on the toothed pulley 114.

[0048] The advantage of the rotating part 11 is that, while switching the grinding head 2, the chamfering tool 105 for chamfering the edges and corners can also be switched synchronously to adapt to edges and corners at different angles. Synchronously switching the grinding head 2 and the chamfering tool 105 can significantly reduce the time required for tool replacement, making the entire processing process smoother and more efficient, without the need to interrupt the operation during the processing to replace the tool, thereby improving the overall production efficiency.

[0049] The transmission member 12 includes a transmission screw 121 rotatably arranged on the guide rail 101, the transmission screw 121 penetrates the sliding plate 102 and is threadedly connected to the sliding plate 102, a fixed block 122 is arranged on the mounting bin 61, a transmission shaft 123 is rotatably arranged on the fixed block 122, a transmission gear 1 124 is arranged on the transmission shaft 123, a transmission gear 2 125 engaged with the transmission gear 1 124 is arranged on the rotating shaft 103, a transmission pulley 126 is arranged on the transmission screw 121 and the transmission shaft 123, and a transmission belt 127 is arranged on the transmission pulley 126.

[0050] When the rotating shaft 62 rotates, it drives the transmission gear 2 125 arranged thereon to rotate. The rotation of the transmission gear 2 125 drives the transmission gear 1 124 engaged therewith to rotate. The rotation of the transmission gear 124 drives the transmission shaft 123 to rotate. When the transmission shaft 123 rotates, it drives the transmission pulley 126 arranged thereon to rotate. The rotation of the transmission pulley 126 drives the transmission belt 127 used in conjunction with it to drive the transmission screw 121 to rotate. The rotation of the transmission screw 121 drives the sliding plate 102 threadedly connected thereto to move. The movement of the sliding plate 102 drives the positioning gear 113 arranged thereon to move. The positioning gear 113 moves During the movement, it engages with the rotating rack 111, thereby driving the positioning shaft 112 to rotate. The rotation of the positioning shaft 112 drives the toothed belt wheel 114 and the toothed belt 115 to rotate, thereby driving the rotating shaft 103 to rotate. The rotation of the rotating shaft 103 drives the deflection rod 104 to rotate, and further switches the chamfering grinder 105 arranged at both ends of the deflection rod 104. At the same time, since the positioning gear 113 is connected to the positioning shaft 112 through a one-way bearing, the deflection rod 104 will not be deflected when the sliding plate 102 is reset, and a damping connection is adopted between the rotating shaft 103 and the sliding plate 102 to improve the stability of the chamfering grinder 105.

[0051] During use, when processing the outer ring of the bearing, first control the power shaft 68 to move and enter the installation chamber 61. The movement of the power shaft 68 is driven by a motor. This is a prior art, so it will not be described in detail here. When the power shaft 68 enters the installation chamber 61, the clamping groove 69 provided thereon engages with the clamping block 67. After the engagement is completed, the power shaft 68 continues to move, synchronously pushing the switching rod 4 and the grinding head 2 connected to the switching rod 4 to extend out of the installation chamber 61 to grind the outer ring of the bearing.

[0052] When there is no need to replace the grinding head 2, it is only necessary to control the overall movement of the grinding machine body 1. When the grinding head 2 needs to be switched, the power shaft 68 is controlled to retract. When the power shaft 68 retracts, it drives the extrusion plate 85 arranged thereon to move, and squeezes the power airbag 81, so that the gas in the power airbag 81 enters the pneumatic chamber 72 and pushes the piston plate 73 to move. The movement of the piston plate 73 drives the pushing rack 74 to move. The movement of the pushing rack 74 drives the pushing gear 75 engaged with it to rotate. The rotation of the pushing gear 75 drives the rotating shaft 62 to rotate. The rotation of the rotating shaft 62 drives the rotating plate 63 and the mounting tube 64 located on both sides of the rotating plate 63 to switch positions. At the same time, because the pushing gear 75 is connected to the rotating shaft 62 through a one-way bearing, the rotating shaft 63 will not be driven to rotate when the pushing rack 74 is reset.

[0053] When the rotating shaft 62 rotates, it drives the transmission gear 2 125 arranged thereon to rotate. The rotation of the transmission gear 2 125 drives the transmission gear 1 124 engaged therewith to rotate. The rotation of the transmission gear 124 drives the transmission shaft 123 to rotate. When the transmission shaft 123 rotates, it drives the transmission pulley 126 arranged thereon to rotate. The rotation of the transmission pulley 126 drives the transmission belt 127 used in conjunction with it to drive the transmission screw 121 to rotate. The rotation of the transmission screw 121 drives the sliding plate 102 threadedly connected thereto to move. The movement of the sliding plate 102 drives the positioning gear 113 arranged thereon to move. The positioning gear 113 moves During the movement, it engages with the rotating rack 111, thereby driving the positioning shaft 112 to rotate. The rotation of the positioning shaft 112 drives the toothed belt wheel 114 and the toothed belt 115 to rotate, thereby driving the rotating shaft 103 to rotate. The rotation of the rotating shaft 103 drives the deflection rod 104 to rotate, and further switches the chamfering grinder 105 arranged at both ends of the deflection rod 104. At the same time, since the positioning gear 113 is connected to the positioning shaft 112 through a one-way bearing, the deflection rod 104 will not be deflected when the sliding plate 102 is reset, and a damping connection is adopted between the rotating shaft 103 and the sliding plate 102 to improve the stability of the chamfering grinder 105.

[0054] Example 2: Please refer to Fig.11 The present invention provides a technical solution: a protective shell 13 is provided on the sliding plate 102 . The design of the protective shell 13 has the advantage of being able to protect the positioning gear 113 and extend the service life of the positioning gear 113 .

[0055] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
