Its main function is to transfer various forces and torques exerted on the wheels to the frame and body, absorb and mitigate vibrations and impacts from the road, reduce noise in the cab, increase passenger comfort, and maintain good operability and stability of the car. The automobile suspension rod usually refers to the connecting rod in the suspension system, including control arms, stabilizer bars (balance bars), tie rods, etc. They work together to support and stabilize the car body.

[0028] 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.

[0029] Example 1

[0030] See also Figure 1-Figure 10 , the present invention provides a technical solution:

[0031] A surface treatment device for an automobile suspension rod comprises a workbench 1 and a grinding box 2, and also comprises a grinding wheel 3. The grinding wheel 3 is located in the grinding box 2, and a plurality of the grinding wheels 3 are provided. After the grinding wheel 3 completes grinding the outer surface of the tie rod ball head, the grinding wheel 3 is controlled to deform to grind the inner ring of the ball head.

[0032] The polishing mechanism 4 is arranged in the polishing box 2, and the grinding wheel 3 is arranged on the polishing mechanism 4. The polishing mechanism 4 drives the grinding wheel 3 to grind the tie rod ball head.

[0033] The advantage of the setting of the polishing mechanism 4 is that it can grind the curved side and the flat side of the tie rod ball head at the same time, and the grinding belt 56 is curved when grinding the curved side. This design allows the curved side and the flat side of the tie rod ball head to be polished at the same time. Compared with grinding each surface separately, the total time required for grinding can be significantly reduced, thereby improving production efficiency. Moreover, grinding the two sides at the same time can ensure that the grinding degree of the two sides is consistent, thereby avoiding the situation where one side is over-grinded and the other side is under-grinded, thereby ensuring the uniformity of the grinding quality. Moreover, the design of the curved grinding belt 56 for the curved side can better fit the shape of the curved surface, reduce idling and ineffective friction during the grinding process, further improve the grinding efficiency, and the curved grinding belt 56 can more accurately control the grinding depth and uniformity of the curved side, thereby helping to achieve higher surface roughness and dimensional accuracy requirements.

[0034] The deformation mechanism 9 is arranged on the polishing mechanism 4. After the grinding wheel 3 completes the grinding of the ball head surface, the deformation mechanism 9 is used to control the grinding wheel 3 to deform and grind the inner ring of the tie rod ball head.

[0035] The advantage of the deformation mechanism 9 is that after the outer side of the tie rod ball head is polished, the deformation of the grinding wheel 3 can be controlled to polish the inner ring of the tie rod ball head. By controlling the deformation of the grinding wheel 3, the inner ring can be accurately polished to avoid damage to the surrounding structure, while ensuring that the dimensional accuracy and surface roughness of the inner ring meet the design requirements. Continuous polishing operations from the outside to the inside can be achieved without replacing equipment or tools, which greatly saves time and labor costs. At the same time, for tie rod ball heads of different sizes and shapes, the deformation degree and polishing parameters of the grinding wheel 3 can be adjusted to adapt to different polishing requirements, thereby improving the versatility and flexibility of the equipment.

[0038] The advantage of setting up the curved surface grinding piece 5 is that the curved grinding belt 56 designed for the curved side can better fit the shape of the curved surface, reduce idling and ineffective friction during the grinding process, and further improve the grinding efficiency. Moreover, the curved grinding belt 56 can more accurately control the grinding depth and uniformity of the curved side, which helps to achieve higher surface roughness and dimensional accuracy requirements.

[0039] The plane grinding part 6 includes a pushing screw 61 rotatably arranged on both sides of the grinding box 2, and an extension rod 62 is arranged on the pushing screw 61. A limit frame 63 is arranged in the grinding box 2, and the limit frame 63 is slidably connected with the extension rod 62. A mounting plate 64 is rotatably arranged at the end of the limit frame 63. The mounting plate 64 has a built-in driving motor, and the built-in driving motor has a locking function and cannot rotate after stopping.

A rotating shaft 68 is rotatably arranged on the steering seat 67, and a connecting seat 69 is arranged on the rotating shaft 68, and the connecting seat 69 is connected to the grinding wheel 3.

[0040] The advantage of setting up the flat grinding piece 6 is that the design allows the curved side and the flat side of the tie rod ball head to be ground at the same time. Compared with grinding each surface separately, the total time required for grinding can be significantly reduced, thereby improving production efficiency. Moreover, grinding the two sides at the same time can ensure that the grinding degree of the two sides is consistent, avoiding the situation where one side is over-grinded and the other side is under-grinded, thereby ensuring the uniformity of the grinding quality.

[0041] The power member 7 includes a plurality of telescopic tubes 71 arranged at the bottom of the polishing box 2, a pressing plate 72 is arranged on the telescopic tube 71, a buffer spring 73 is sleeved on the telescopic tube 71, a power airbag 74 is arranged at the bottom of the pressing plate 72 in the polishing box 2, a return spring 75 is arranged in the power airbag 74, a return plate 76 is arranged on the return spring 75, a rotating gear 77 is arranged on the bidirectional screw rod 51, a positioning shaft 78 is arranged in the polishing box 2, and a positioning shaft 78 is arranged on the positioning shaft 78 The wheel 77 is meshed with an amplifying gear 79, and a pneumatic bin 710 is arranged in the polishing box 2. A piston plate 711 is slidably arranged in the pneumatic bin 710, and a power rack 712 meshed with the amplifying gear 79 is arranged on the piston plate 711. An air guide tube 713 is arranged on the power airbag 74, and one end of the air guide tube 713 is connected to the pneumatic bin 710. A synchronous pulley 714 is arranged at one end of the bidirectional screw rod 51 away from the rotating gear 77, and a synchronous belt 715 is arranged on the synchronous pulley 714.

[0042] During operation, the staff first places the ball head of the pull rod into the polishing box 2, and then presses the pull rod to drive the pressing plate 72 to descend. The pressing plate 72 descends and squeezes the power airbag 74. At this time, the gas in the power airbag 74 enters the pneumatic chamber 710 through the air guide tube 713. At this time, high pressure is generated in the pneumatic chamber 710 to push the piston plate 711 and the power rack 712 set on the piston plate 711 to move. The movement of the power rack 712 drives the enlarged gear 79 engaged with it to rotate, and the rotation of the enlarged gear 79 drives the rotating gear 77 to rotate. The rotation of the rotating gear 77 drives the two-way screw 51 connected to it to rotate. The rotation of a single two-way screw 51 drives the synchronous pulley 714 to rotate, and then the synchronous belt 715 drives multiple two-way screws 51 to rotate synchronously. The rotation of the two-way screw 51 drives the mounting frames 52 at both ends to move toward the middle until they contact the ball head of the pull rod.

[0043] When the ball head of the tie rod contacts the polishing belt 56 , the polishing belt 56 is squeezed and the deformable rod 58 is driven to move to overcome the elastic force of the push spring 511 , so that the polishing belt 56 presents an arc shape and fits the arc surface of the ball head of the tie rod.

[0044] The driving member 8 includes a driving groove 81 provided on the side wall of the polishing box 2, a rotating shaft 82 is rotatably provided in the driving groove 81, and synchronous gears 83 are provided at both ends of the rotating shaft 82.

[0045] When the power airbag 74 is squeezed, the gas synchronously passes through the ventilation pipe 816 and enters the driving chamber 813. At this time, high pressure is formed in the driving chamber 813 to push the piston plate 2 814 and the driving rack 815 arranged thereon to move. The movement of the driving rack 815 pushes the driving gear 3 812 engaged therewith to rotate. The rotation of the driving gear 3 812 drives the driving shaft 810 to rotate. The rotation of the driving shaft 810 drives the driving gear 2 811 to rotate. The rotation of the driving gear 2 811 drives the driving gear 1 88 engaged therewith to rotate.

At the same time, the advantage of the arrangement of the telescopic screw 65 and the extension tube 66 is that the distance between the grinding wheel 3 and the mounting plate 64 can be adjusted according to the size of the inner ring diameter of the pull rod.

[0046] The deformation mechanism 9 includes a deflection member 10 disposed on the extension rod 62 , through which the grinding wheel 3 is controlled to deflect and deform.

[0048] The advantage of setting up the deflection member 10 is that continuous grinding operations from the outside to the inside can be achieved without changing equipment or tools, which greatly saves time and labor costs. At the same time, for tie rod ball heads of different sizes and shapes, the deformation degree and grinding parameters of the grinding wheel 3 can be adjusted to adapt to different grinding requirements, thereby improving the versatility and flexibility of the equipment.

[0049] The adjusting member 11 includes a fixing ring 111 arranged on the mounting tube 101, an adjusting screw 112 is rotatably arranged on the fixing ring 111, the adjusting screw 112 passes through the sliding plate 102, an adjusting gear 113 is arranged at one end of the adjusting screw 112, an inner gear ring 114 which meshes with the adjusting gear 113 is rotatably arranged on the fixing ring 111, an annular plate 115 is arranged on the inner gear ring 114, a slot 116 is opened on the annular plate 115, an adjusting rod 117 is rotatably arranged in the polishing box 2, and an adjusting gear 118 which meshes with the slot 116 is arranged on the adjusting rod 117.

[0050] When the grinding of the side of the tie rod ball head is completed, the staff stops pressing the pressing plate 72 to reset the grinding wheel 3, and then the staff rotates the adjusting rod 117 to drive the adjusting gear 118 to rotate.

The rotation of the connecting seat 69 drives the grinding wheel 3 to rotate, thereby realizing the deflection deformation of the grinding wheel 3.

[0051] When in use, the staff first places the ball head position of the pull rod into the polishing box 2, and then presses the pull rod to drive the pressing plate 72 to descend. The pressing plate 72 descends and squeezes the power airbag 74. At this time, the gas in the power airbag 74 enters the pneumatic chamber 710 through the air guide tube 713. At this time, high pressure is generated in the pneumatic chamber 710 to push the piston plate 711 and the power rack 712 set on the piston plate 711 to move. The movement of the power rack 712 drives the enlarged gear 79 engaged with it to rotate, and the rotation of the enlarged gear 79 drives the rotating gear 77 to rotate. The rotation of the rotating gear 77 drives the two-way screw 51 connected to it to rotate. The rotation of a single two-way screw 51 drives the synchronous pulley 714 to rotate, and then the synchronous belt 715 drives multiple two-way screws 51 to rotate synchronously. The rotation of the two-way screw 51 drives the mounting frames 52 at both ends to move toward the middle until they contact the ball head position of the pull rod.

[0052] When the ball head of the tie rod contacts the polishing belt 56 , the polishing belt 56 is squeezed and the deformable rod 58 is driven to move to overcome the elastic force of the push spring 511 , so that the polishing belt 56 presents an arc shape and fits the arc surface of the ball head of the tie rod.

[0053] When the power airbag 74 is squeezed, the gas synchronously passes through the ventilation pipe 816 and enters the driving chamber 813. At this time, high pressure is formed in the driving chamber 813 to push the piston plate 2 814 and the driving rack 815 arranged thereon to move. The movement of the driving rack 815 pushes the driving gear 3 812 engaged therewith to rotate. The rotation of the driving gear 3 812 drives the driving shaft 810 to rotate. The rotation of the driving shaft 810 drives the driving gear 2 811 to rotate. The rotation of the driving gear 2 811 drives the driving gear 1 88 engaged therewith to rotate. The rotation of the driving gear 1 88 drives the linkage shaft 84 to rotate. The rotation of the linkage shaft 84 drives the linkage gear The one 85 and the connecting gear two 86 rotate synchronously, the rotation of the connecting gear one 85 drives the synchronous gear 83 and the rotating shaft 82 to rotate, thereby driving the connecting shafts 84 on both sides to rotate synchronously, the rotation of the connecting gear two 86 drives the connecting gear three 87 engaged with it to rotate, the rotation of the connecting gear three 87 drives the pushing screw 61 to rotate, the pushing screw 61 rotates to drive the extension rod 62 to move, and drives the mounting plate 64 and the grinding wheel 3 located on the mounting plate 64 to fit the side of the pull rod ball head. At the same time, the advantage of the arrangement of the telescopic screw 65 and the extension tube 66 is that the distance between the grinding wheel 3 and the mounting plate 64 can be adjusted according to the size of the inner ring diameter of the pull rod.

[0054] When the grinding of the side of the tie rod ball head is completed, the staff stops pressing the pressing plate 72 to reset the grinding wheel 3, and then the staff rotates the adjusting rod 117 to drive the adjusting gear 118 to rotate. The adjustment gear 118 rotates to drive the engaging slot 116 to rotate, and drives the annular plate 115 to rotate. The rotation of the annular plate 115 drives the inner ring 114 to rotate. The rotation of the inner ring 114 drives the adjusting gear 113 to rotate. The rotation of the adjusting gear 113 drives the adjusting screw 112 to rotate. The rotation of the adjusting screw 112 drives the sliding plate 102 to move on the mounting tube 101, and drives the deflection rack 103 connected to the sliding plate 102 to move. The movement of the deflection rack 103 drives the deflection gear 104 to rotate, thereby driving the rotating shaft 68 and the connecting seat 69 to rotate. The rotation of the connecting seat 69 drives the grinding wheel 3 to rotate, thereby realizing the deflection deformation of the grinding wheel 3.
