[0115] By arranging at least one reaction force mechanism 1 in sequence on the support mechanism 2, the technical effect of batch clamping of gears and batch providing of reaction force is achieved, further improving the efficiency of gear clamping, feeding, and screwing of gears.

[0116] In a preferred embodiment, the clamping mechanism 11 includes: a clamping structure 111, an air gripper 112 and an adjustment structure 113;

[0117] The clamping claw structure 111 is used to clamp the gear;

[0119] The adjustment structure 113 is connected to the clamping structure 111 . The adjustment structure 113 is used to adjust the clamping size of the clamping structure 111 . The clamping size is the diameter of the gear clamped by the clamping structure 111 .

[0120] In this example, the automatic clamping of the gear and the provision of reaction force are achieved by setting a clamping claw structure 111; the air claw 112 is provided to provide pressure for the clamping claw structure 111 to clamp the gear; and the adjustment structure 113 is provided to adjust the clamping gear, so that the clamping claw mechanism 11 can clamp gears of various diameters, thereby expanding the scope of use of the device of the present application.

[0121] Optionally, the clamping mechanism 11 further includes a positioning structure 116;

[0122] The positioning structure 116 cooperates with the adjustment structure 113 to contact and fix the gear.

[0123] The adjustment structure 113 is mounted on one finger of the air gripper 112 , and the positioning mechanism 116 is mounted on the other finger of the air gripper 112 .

[0124] Specifically, the adjustment structure 113 includes: a centering plate 1131, an adjustment plate 1132, a guide column 1133, a linear bearing 1134, a threaded seat 1135 and a rectangular spring 1136;

[0125] The centering plate 1131 is located in the clamping space of the clamping claw structure 111. The clamping space is used to place the gears. The centering plate 1131 is used to adjust the clamping size of the clamping space.

[0126] One end of the guide column 1133 is connected to the centering plate 1131, and the guide column 1133 is used to fix the centering plate 1131 on the clamping claw structure 111;

[0127] The adjustment plate 1132 is located outside the clamping jaw structure 111, and the clamping jaw structure 111 is provided with a linear bearing 1134; the linear bearing 1134 is connected to both sides of the clamping jaw structure 111, and a rectangular spring 1136 is coaxially arranged inside the linear bearing 1134;

[0128] The other end of the guide column 1133 passes through the rectangular spring 1136 and the adjustment plate 1132 in sequence, and is connected to the threaded seat 1135; the adjustment plate 1132 is used to adjust the position of the centering plate 1131 in the clamping space to adjust the clamping size of the clamping space;

[0129] The threaded seat 1135 is connected to the guide column 1133 through threads, and the threaded seat 1135 provides tension to the rectangular spring 1136 through threaded connection. The elastic force generated by the rectangular spring 1136 according to the tension cooperates with the tension provided by the threaded seat 1135 to fix the adjustment seat, guide column 1133 and centering plate 1131 on the clamping structure 111.

[0130] In this example, a centering plate 1131 is provided to cooperate with the inner wall of the clamping space to clamp the gear, and an adjustment plate 1132 and a guide column 1133 are provided to adjust the position of the centering plate 1131 in the clamping space, thereby adjusting the diameter of the gear clamped by the clamping mechanism 11; a rectangular spring 1136 and a threaded seat 1135 are provided to cooperate with each other, thereby fixing the guide column 1133 and the adjustment plate 1132 on the clamping structure.

[0137] Among them, the M8 proximity switch is used as the first proximity switch 1139. The M8 proximity switch is an M8 cylindrical proximity switch. It uses the eddy current principle through the inductive proximity switch to effectively detect various metal workpieces. It has the advantages of high measurement accuracy and high response frequency. It uses non-contact position detection, has no wear on the surface of the target object, and has extremely high reliability. The clearly visible indicator light design makes it easier to judge the working status of the switch.

[0138] Further, the contoured tooth 1137 has a V-shaped groove 11371, and the V-shaped groove 11371 is used to contact the outer contour of the gear located in the clamping space;

[0153] The positioning block 126 is slidably connected to the guide rail 125 , and the positioning block 126 is connected to the clamping mechanism 11 .

[0154] In this example, the connection between the moving mechanism 13 and the clamping mechanism 11 is achieved by setting an L-shaped connecting plate 121, and the direct collision between the L-shaped connecting plate 121 and the supporting mechanism 2 to cause damage is avoided by setting a positioning plate 122, an oil pressure buffer 123 and a first cushion block 124; by setting a guide rail 125 and a positioning block 126 that is slidably connected to the guide rail 125 and connected to the air claw 112 of the clamping mechanism 11, it is ensured that the clamping mechanism 11 can move axially along the guide rail 125, thereby ensuring the reliability of the movement of the clamping mechanism 11.

Among them, the first cushion block 124 is a buffer block made of polyurethane, the full name of which is polyurethane, which is a polymer compound. It has good stability, chemical resistance, resilience and mechanical properties.

[0159] One end of the push rod 129 connected with the nut 1210 is used to contact the vertical portion of the L-shaped connecting plate 121 .

[0160] In this example, the oil-free bushing 127 is also called a self-lubricating bearing, which is a novel lubricating bearing having the characteristics of both a metal bearing and an oil-free lubricating bearing, with a metal base bearing the load and a specially formulated solid lubricating material gas lubricating effect;

[0161] The sliding connection between the guide rod 128 and the oil-free bushing 127 is achieved by inserting the guide rod 128 into the oil-free bushing 127. At the same time, the clamping force between the oil-free bushing 127 and the guide rod 128 can be adjusted as needed.
