[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example: Please refer to Figure 1-7 This utility model provides a technical solution: an auxiliary tooling for repairing and grinding composite materials, including a main frame 1, two protective doors 2 rotatably mounted on the main frame 1, a workbench 3 rotatably mounted on the main frame 1, a first protective pad 4 mounted on the workbench 3, a composite material body 5 mounted on the first protective pad 4, a grinding mechanism mounted on the main frame 1, a transverse translation mechanism mounted on the grinding mechanism, a longitudinal translation mechanism mounted on the transverse translation mechanism, an angle adjustment mechanism mounted on the longitudinal translation mechanism, the angle adjustment mechanism mounted on the grinding mechanism, a dust removal mechanism and a spraying mechanism mounted on the main frame 1, and a clamping mechanism mounted on the first protective pad 4, the clamping mechanism being in contact with the composite material body 5. The workbench 3 can be rotated and adjusted on the main frame 1 to facilitate changing the grinding angle of the composite material body 5, thereby enabling grinding treatment of different positions of the composite material body 5.
[0028] The grinding mechanism includes a slider 6, which is slidably mounted on the top inner wall of the main frame 1 in a left-right direction. A movable block 61 is mounted on the slider 6, a partition 62 is mounted on the movable block 61, a sliding plate 63 is slidably mounted on the partition 62 in a front-back direction, a first electric telescopic rod 64 is mounted on the sliding plate 63, a baffle 65 is mounted on the first electric telescopic rod 64, two uprights 66 are mounted on the baffle 65, a rotating shaft 67 is rotatably mounted on the two uprights 66, a mounting plate 68 is mounted on the rotating shaft 67, and a drive shaft 69 is rotatably mounted on the mounting plate 68. A grinding wheel 610 is mounted on one end of the drive shaft 69. The grinding wheel 610... The composite material body 5 is in contact with the support plate 611 mounted on the mounting plate 68. The servo motor 612 is mounted on the support plate 611. The servo motor 612 is coaxially connected to the drive shaft 69. By using the action of the first electric telescopic rod 64, the vertical distance between the grinding wheel 610 and the composite material body 5 can be conveniently controlled, so that the composite material body 5 can be precisely ground. The main frame 1 is equipped with a safety door 2. Closing the safety door 2 can prevent flying debris from injuring people during the grinding process. Preferably, an emergency stop button can be provided to ensure that the power can be quickly cut off in an emergency to ensure the safety of the operator.
[0029] Furthermore, the lateral translation mechanism includes a first forward and reverse motor 7, which is mounted on the inner wall of one side of the main frame 1. A lead screw 71 is mounted on the first forward and reverse motor 7, and the other end of the lead screw 71 is rotatably mounted on the inner wall of the main frame 1. The movable block 61 is threaded onto the lead screw 71. The longitudinal translation mechanism includes two second forward and reverse motors 9, both of which are mounted on the partition plate 62. A rotating shaft 91 is rotatably mounted on each of the two second forward and reverse motors 9. A first gear 92 is mounted on each of the two rotating shafts 91. A toothed belt 93 meshes with each of the two first gears 92. The two toothed belts 93 are respectively mounted on both sides of the sliding plate 63. By rotating the first forward and reverse motor 7, the lead screw 71 is driven to rotate, thereby driving the movable block 61 to move in the left and right directions, thus controlling the grinding wheel 610 to perform lateral translation in the horizontal direction. The second forward and reverse motor 9 rotates, thereby driving the first gear 92 to rotate. Since the first gear 92 meshes with the toothed belt 93 of the sliding plate 63, the sliding plate 63 is driven to move relative to the partition 62 in the front-back direction, thereby driving the grinding wheel 610 to move longitudinally in the horizontal direction. This can effectively control the grinding wheel 610 to move to different positions for grinding.
[0030] Furthermore, the angle adjustment mechanism includes a third electric telescopic rod 10, which is mounted on a baffle 65. A transition rod 101 is mounted on the third electric telescopic rod 10, and two racks 102 are mounted on the transition rod 101 in the left-right direction. Both racks 102 are slidably mounted on the baffle 65. Two second gears 103 are sleeved on the rotating shaft 67, and the two second gears 103 mesh with the two racks 102 respectively. The third electric telescopic rod 10 drives the racks 102 to move, and the racks 102 drive the second gears 103 to rotate, thereby facilitating the adjustment of the grinding wheel 610 at different angles.
[0031] Furthermore, the clamping mechanism includes multiple second electric telescopic rods 8, all of which are mounted on the first protective pad 4. Each second electric telescopic rod 8 is equipped with a gripper 81, and each gripper 81 is equipped with a second protective pad 82. The second protective pad 82 is in contact with the outer surface of the composite material body 5. The second electric telescopic rods 8 drive the gripper 81 to move, thereby achieving a stable clamping of the composite material body 5. The second protective pad 82 covering the surface of the gripper 81 prevents damage to the composite material body 5 during the clamping process.
[0032] Furthermore, the dust removal mechanism includes two dust collection boxes 11, which are respectively installed on the outer surfaces of both sides of the main frame 1. Each of the two dust collection boxes 11 is equipped with an exhaust fan 111. The air inlet of the exhaust fan 111 is connected to a connecting pipe 112, and its air outlet is connected to the inside of the dust collection box 11. The ends of the two connecting pipes 112 are located in the main frame 1 and face the composite material body 5. The dust generated by the grinding wheel 610 is collected into the dust collection box 11 by the exhaust fan 111 through the connecting pipe 112, which is used to collect the dust generated during the grinding process and keep the working environment clean.
[0033] Furthermore, the spraying mechanism includes a liquid storage tank 12, which is installed on the outer surface of the main frame 1. A water pump 121 is installed on the liquid storage tank 12. The inlet end of the water pump 121 is connected to the liquid storage tank 12, and a spray pipe 122 is installed at its outlet end. The head end of the spray pipe 122 is located in the main frame 1 and faces the composite material body 5. The water pump 121 sprays the coolant in the liquid storage tank 12 onto the surface of the composite material body 5, which can cool the polishing area in a timely manner and prevent material damage or deformation caused by high temperature.
[0034] The working principle is as follows: When the composite material body 5 needs to be polished, first place the composite material body 5 on the first protective pad 4, then activate the switch on the second electric telescopic rod 8. The second electric telescopic rod 8 drives the gripper 81 to move, and the gripper 81 drives the second protective pad 82 to move towards the center, thus conveniently fixing the composite material body 5 on the first protective pad 4. Next, activate the switches on the servo motor 612, the first electric telescopic rod 64, the water pump 121, and the exhaust fan 111 in sequence. The servo motor 612 drives the drive shaft 69 to rotate, and the drive shaft 69 drives the polishing wheel 610 to rotate, thus conveniently polishing the composite material body 5. In preparation for grinding the composite material body 5, the first electric telescopic rod 64 is used to drive the baffle 65 to move downward. The baffle 65 drives the rotating grinding wheel 610 to approach the composite material body 5, so that the composite material body 5 can be ground conveniently. At this time, the exhaust fan 111 is used to conveniently suck the dust generated by the grinding wheel 610 into the dust collection box 11 for storage through the connecting pipe 112. During the grinding process, the water pump 121 is used to spray the coolant in the liquid storage tank 12 onto the surface of the composite material body 5 through the spray pipe 122, which can effectively cool the surface of the composite material body 5.
[0035] When different positions need to be polished, the switch on the first forward and reverse motor 7 is turned on, which drives the lead screw 71 to rotate. The lead screw 71 drives the movable block 61 to move laterally in the horizontal direction, thereby driving the polishing wheel 610 to move laterally on the composite material body 5. At the same time, the switch on the second forward and reverse motor 9 is turned on, which drives the rotating shaft 91 to rotate. The rotating shaft 91 drives the first gear 92 to rotate. The first gear 92 drives the toothed belt 93 to move. The toothed belt 93 drives the sliding plate 63 to move, thereby driving the polishing wheel 610 to move longitudinally in the horizontal direction. Thus, the polishing wheel 610 can be conveniently used to polish different positions on the composite material body 5.
[0036] When it is necessary to grind the composite material body 5 at different angles, simply activate the switch on the third electric telescopic rod 10. The third electric telescopic rod 10 will drive the adapter rod 101 to move, the adapter rod 101 will drive the rack 102 to move, the rack 102 will drive the second gear 103 to rotate, the second gear 103 will drive the rotating shaft 67 to rotate, and the rotating shaft 67 will drive the mounting plate 68 to rotate. This will allow for convenient angle adjustment of the grinding wheel 610, enabling grinding of the composite material body 5 at multiple angles.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
