Detailed Description
The invention will be further described with reference to the following specific embodiments and the accompanying drawings.
As shown in the figure: the transmission locking device comprises a mounting plate 1, a servo motor 10, a speed reducer 7, a rack 9 and an elastic device. Wherein the servo motor 10 is connected with the speed reducer 7 and is arranged on the mounting plate 1 by the motor base 3 in a sliding way, and the output shaft of the speed reducer 7 is provided with a gear 8. The gear 8 is pressed on the rack 9 by an elastic device, the rack 9 and the elastic device are positioned on the same side of the gear 8, and the gear 8 and the rack 9 adopt high-precision structures for ensuring the transmission precision. The elastic device comprises a screw rod 6, a nut seat 4, a nut 5 and a spring 2, wherein the nut seat 4 is installed on the installation plate 1, and one end of the screw rod 6 penetrates through the nut seat 4 to be connected with the motor seat 3 and is used for driving the nut seat 4 to slide relative to the installation plate 1; the other end of the screw rod 6 is provided with a nut 5, and a spring 2 is sleeved on the screw rod 6 between the nut seat 4 and the nut 5.
Specifically, be equipped with track 12 on the mounting panel 1, be equipped with slider 11 on the motor cabinet 3, motor cabinet 3 utilizes track 12 and slider 11 slidable mounting on mounting panel 1, and motor cabinet 3 and mounting panel 1 can also adopt guide way and guide bar or other modes sliding fit. To improve the stability of the mechanism, the rails 12 and the sliders 11 may be provided in two sets along both sides of the motor mount 3. Rack 9 and motor cabinet 3 are located the both sides of mounting panel 1, and the output shaft of speed reducer 7 passes mounting panel 1 and is equipped with gear 8, compares in the mounting means of homonymy, and structural stability is higher, and it is more convenient to install.
The working principle is as follows: the rack 9 and the elastic device are arranged above the gear 8, the nut 5 is screwed, the spring 2 is compressed and rebounded under stress, the screw rod 6 moves upwards to drive the nut seat 4 and the sliding block 11 to slide upwards along the track 12, and the purpose of locking the gear 8 is achieved; when the device moves, the servo motor 10 transmits the force to the speed reducer 7, the gear 8 on the output shaft of the speed reducer moves back and forth along the rack 9, and if a load (load, scrap iron and the like) exists in the moving process, the gear 8 can be adjusted in a self-adaptive mode through the sliding block 11 and the track 12 under the action of the spring 2.
