Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 3 As shown, a forklift gantry support and gantry small component mounting mold includes a driving mechanism 1, a sliding mechanism 2, a gantry small component positioning mechanism 3 and a gantry support positioning mechanism 4. Two gantry small component positioning mechanisms 3 are arranged on the sliding mechanism 2 and connected to the driving mechanism 1. A gantry support positioning mechanism 4 is arranged on the gantry small component positioning mechanism 3. The gantry small component positioning mechanism 3 is used to position the gantry small component, and the gantry support positioning mechanism 4 is used to position the gantry support. The driving mechanism 1 can drive the gantry small component positioning mechanism 3 to slide on the sliding mechanism 2 to move closer to or away from each other, so as to position components of different sizes, thereby realizing automatic positioning, convenient operation, strong compatibility and high positioning accuracy.

[0024] like Figure 1-Figure 3As shown, the driving mechanism 1 includes a servo motor 11, a ball screw 12 and a coupling 13. The output end of the servo motor 11 is fixedly connected to the ball screw 12. The output end of the servo motor 11 is fixedly connected to the coupling 13. The coupling 13 is connected to the ball screw 12. The ball screw 12 is a product that converts rotational motion into linear motion. A nut is arranged on the ball screw 12. The rotation of the screw can make the nut arranged on the ball screw 12 move linearly. The coupling 13 rotates together during the process of transmitting motion and power to play an overload protection role. The sliding mechanism 2 includes a base plate 21 and a linear rail 22. Two parallel linear rails 22 are fixedly connected to the top of the base plate 21. The linear rail 22 is parallel to the ball screw 12. The door frame small component positioning mechanism 3 includes a positioning seat 31 and an L-shaped bent plate positioning plate 32. Various bolts and pads are compounded on the L-shaped bent plate positioning plate 32 to achieve Height, front and back, left and right multi-directional adjustment, the entire positioning block is not only small in size, strong in compatibility, and easy to adjust, but also is pivoted on the electric mold frame with positioning pins and bolts. It is not only highly accurate, but can also be remade after wear and tear, and is easy to replace. The bottom of the positioning seat 31 is slidably connected to the linear rail 22, and the top of the positioning seat 31 is fixedly connected with an L-shaped bent plate positioning plate 32. The L-shaped bent plate positioning plate 32 is provided with a positioning plate, a pad, a pressure plate and bolts. The nut on the ball screw 12 is fixedly connected to the bottom end of the positioning seat 31, and the door frame support positioning mechanism 4 includes a wheel disc 41, which can position the door frame support. The upper part of the L-shaped bent plate positioning plate 32 is fixedly connected with a connecting shaft 5, and the end of the connecting shaft 5 away from the L-shaped bent plate positioning plate 32 is fixedly connected to the wheel disc 41. A plurality of screws are arranged on the outside of the base plate 21 through the plate, and bolts are arranged around the base plate 21 to assist in positioning the small components of the door frame.

[0025] In the specific implementation process, firstly, the small component of the gantry is hoisted onto the mold, and positioned with the mold end face and the bolts set beside it, and then pressed with the pressure plate and bolts on the L-shaped bent plate positioning plate 32. The positioning plate, pad and pressure plate on the L-shaped bent plate positioning plate 32 fully consider the versatility of various types of gantry. The mold can be powered by a full range of 2.5T, 3T, and 3.5T gantry, and has strong compatibility. The output end of the servo motor 11 rotates to drive the ball screw 12 to rotate, and the nut on the ball screw 12 moves linearly, and the positioning seat 31 It slides on the linear rail 22, and then drives the positioning seat 31 to move linearly. The linear movement of the positioning seat 31 on the linear rail 22 is used to realize the connection of workpieces of different types and sizes. The servo motor 11 drives the ball screw 12 to transmit. The positioning seat 31 is moved to the position corresponding to the opening of the door frame support that needs to be connected through the program. Because the openings of different door frame supports are different, the positions to which the positioning seat 31 needs to be moved are also different. The servo motor 11 can drive the ball screw 12 to move on the linear rail 22 to adapt to the connection of different openings, which is very convenient.

[0026] When erecting the mast support, directly insert the mast support between the mast subassembly and the wheel disc 41, align the end face with the positioning surface of the wheel disc 41, and tighten it with a Haver cover and M16 bolts in the circumferential direction. Then use a welding gun to spot weld the mast subassembly and the mast support together to complete the erection. A small gap is used between the mast support and the wheel disc 41. When the mast support is erected and needs to be demoulded, the positioning seat 31 can easily drive the wheel disc 41 to retract and disengage from the mast support. Then the two positioning seats 31 retract to the origin. After the positioning seats 31 return to the origin, there is enough space on the end face of the wheel disc 41 to demould the mast support and the mast subassembly that are erected into one. After the demoulding is completed, the next mast subassembly and mast support can be erected immediately. The erection process is smooth, and the mold is efficient, labor-saving, and reliable.
