[0026] like Figures 1 to 4 As shown, a scissor lift for automobile production includes a scissor lift 1, which includes a top plate 101. A slot is provided on the upper surface of the top plate 101. A positioning mechanism 2 is provided inside the slot of the top plate 101 to limit the moving position of the automobile frame at the upper end of the top plate 101. A groove is provided inside the positioning mechanism 2. A limiting mechanism 4 is installed inside the groove of the positioning mechanism 2. Specifically, by starting the positioning mechanism 2, the left and right sides of the positioning mechanism 2 are layered and attached to the special-shaped inner wall of the automobile frame, so that the contact surface between the positioning mechanism 2 and the inner wall of the automobile frame is increased, thereby minimizing the movement of the automobile frame at the upper end of the top plate 101 when the positioning mechanism 2 positions the automobile frame subsequently, thereby improving the stability of the scissor lift 1 during the positioning process, thereby improving the practicality of the device.

[0027] like Figure 1 , Figure 2 and Figure 4As shown, the positioning mechanism 2 includes a motor 201 and a bidirectional threaded rod 204. Through holes are provided on the inner walls of the left and right sides of the card slot of the scissor-type lifting platform 1. The bidirectional threaded rod 204 is rotatably connected to the two groups of through holes of the scissor-type lifting platform 1. The motor 201 is installed on the left side of the scissor-type lifting platform 1, and the output shaft of the motor 201 is installed on the left side of the bidirectional threaded rod 204. The external threads of the bidirectional threaded rod 204 are connected with two groups of fixed plates 202. Multiple groups of spring telescopic rods 203 are provided on the opposite sides of the two groups of fixed plates 202. Positioning blocks 205 are installed on the side of the multiple groups of spring telescopic rods 203 away from the adjacent group of fixed plates 202. Specifically, when the subsequent automobile frame is hoisted to the upper end of the top plate 101, the bidirectional threaded rod 204 is triggered by starting the motor 201. The two groups of fixed plates 202 move, and the multiple groups of positioning blocks 205 are respectively abutted against the left and right inner walls of the automobile frame on one side away from the adjacent group of fixed plates 202, and then the multiple groups of spring telescopic rods 203 have good elastic potential energy, so that the subsequent multiple groups of spring telescopic rods 203 push the multiple groups of positioning blocks 205 in layers to move so that the multiple groups of positioning blocks 205 are closely fitted to the special-shaped inner wall of the automobile frame on one side away from the adjacent group of fixed plates 202, thereby increasing the contact surface between the positioning mechanism 2 and the automobile frame, thereby avoiding as much as possible the movement of the automobile frame on the upper end of the top plate 101 when the subsequent positioning mechanism 2 positions the automobile frame, thereby improving the stability of the scissor lift 1 during the positioning process, thereby improving the practicality of the device.

[0028] like Figure 1 and Figure 4 As shown, the plurality of positioning blocks 205 are bonded with silicone pads 3 on one side away from the adjacent group of fixing plates 202; specifically, the plurality of silicone pads 3 are respectively arranged between the contact surfaces of the plurality of positioning blocks 205 and the automobile frame, so that the subsequent plurality of silicone pads 3 shield and protect the contact surfaces between the plurality of positioning blocks 205 and the automobile frame, thereby avoiding as much as possible that the subsequent plurality of positioning blocks 205 position the automobile frame at the upper end of the top plate 101 and leave scratches on the inside of the automobile frame.

[0029] like Figure 2 As shown, a groove is provided on the upper surface of the top plate 101, and a buffer pad 6 is bonded inside the groove of the top plate 101; specifically, the buffer pad 6 is arranged on the upper surface of the top plate 101, so that when a subsequent automobile frame is placed on the upper surface of the top plate 101, the buffer pad 6 buffers the development of the automobile frame on the upper surface of the top plate 101, thereby avoiding as much as possible the collision between the automobile frame and the upper surface of the top plate 101 during the process of placing the automobile frame by subsequent staff, thereby avoiding as much as possible the damage to the automobile frame during the process of placing the automobile frame by subsequent staff.

[0030] like Figures 1 to 3As shown, the limiting mechanism 4 includes two groups of bidirectional electric telescopic rods 401, and the front sides of the two groups of fixed plates 202 are provided with through holes. The two groups of bidirectional electric telescopic rods 401 are respectively installed inside the through holes of the two groups of fixed plates 202, and the front and rear output ends of the two groups of bidirectional electric telescopic rods 401 are respectively installed with limiting blocks 402; specifically, when the subsequent multiple groups of positioning blocks 205 are away from the side of the adjacent group of fixed plates 202 and respectively abut against the left and right inner walls of the automobile frame, the four groups of limiting blocks 402 are pushed to move by starting the two groups of bidirectional electric telescopic rods 401, and the four groups of limiting blocks 402 are away from the side of the adjacent group of fixed plates 202 and respectively abut against the four end corners of the automobile frame, so that the two groups of limiting mechanisms 4 can perform secondary positioning on the position of the automobile frame at the upper end of the top plate 101 at four angles of front, back, left and right during use, thereby minimizing the movement of the subsequent automobile frame during the production and processing process.

[0031] like Figure 1 and Figure 2 As shown, a U-shaped limit plate 5 is installed on one side of the top plate 101 close to the motor 201, and the position of the motor 201 is located inside the U-shaped limit plate 5; specifically, the position of the U-shaped limit plate 5 is set at the outer end of the motor 201, so that the U-shaped limit plate 5 limits the moving position of the motor 201 during the subsequent staff's transportation of the mobile scissor lift 1, thereby avoiding as much as possible the subsequent staff's transportation of the mobile scissor lift 1. The motor 201 is damaged due to collision with foreign objects, thereby increasing the service life of the motor 201.

[0032] In summary, the two sets of fixed plates 202 are triggered to move by starting the motor 201 to drive the bidirectional threaded rod 204, so that the multiple sets of positioning blocks 205 are respectively abutted against the left and right inner walls of the automobile frame on one side away from the adjacent set of fixed plates 202, and then the multiple sets of spring telescopic rods 203 have good elastic potential energy, so that the subsequent multiple sets of spring telescopic rods 203 push the multiple sets of positioning blocks 205 in layers to move so that the multiple sets of positioning blocks 205 are closely attached to the special-shaped inner wall of the automobile frame away from the side of the adjacent set of fixed plates 202, thereby increasing the positioning mechanism 2 and the automobile frame. The contact surface of the frame is formed by the two sets of two-way electric telescopic rods 401, thereby preventing the automobile frame from moving on the upper end of the top plate 101 when the subsequent positioning mechanism 2 positions the automobile frame; by starting the two sets of two-way electric telescopic rods 401 to push the four sets of limit blocks 402 to move, the four sets of limit blocks 402 are respectively abutted against the four end corners of the automobile frame on the side away from the adjacent set of fixed plates 202, so that the two sets of limit mechanisms 4 can perform secondary positioning on the position of the automobile frame on the upper end of the top plate 101 at four angles of front, back, left, and right during use, thereby preventing the subsequent automobile frame from moving during the production and processing process.
