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.

[0020] Example: Figure 1-4 As shown, the utility model provides a technical solution: a gantry gear head positioning device, including a base 1, a moving wheel 11 is fixedly connected to the bottom of the base 1 near the corners, a square box 4 is fixedly connected to the center of the bottom of the base 1, a vertical plate 47 is symmetrically fixedly connected to the bottom of the base 1 near the square box 4, and legs 49 are symmetrically slidably inserted in the two vertical plates 47 near the center of the bottom, a clamping plate 13 is fixedly connected to the top of the base 1 near the center, and a slide groove 1 is opened at the top of the base 1 near the center of one side. 4. A slide bar 3 is slidably connected inside the slide groove 14, and the slide bar 3 and the clamping plate 13 are at the same level. One end of the slide bar 3 close to the clamping plate 13 is symmetrically fixedly connected to a support plate 1 32, and a rotating block 33 is rotatably connected between the two support plates 1 32. One end of the rotating block 33 close to the clamping plate 13 is fixedly connected to a support plate 2 34, and the support plate 2 34 is close to one end of the clamping plate 13 and is symmetrically fixedly connected to an M plate 35 in an upper and lower manner. A limiting wheel 36 is symmetrically rotatably connected between the two M plates 35 and on one side close to the clamping plate 13.

[0021] An electric cylinder 12 is fixedly installed at the top of the base 1 near the center of one side, and the output end of the electric cylinder 12 is fixedly connected to the slide rod 3.

[0022] By adopting the above technical solution, the electric cylinder 12 is operated, so that the fixedly connected sliding rod 3 moves horizontally.

[0023] A mainboard 2 is fixedly connected to the top of the base 1 near one end, and a mounting frame 21 is slidably connected to the front end of the mainboard 2 .

[0024] By adopting the above technical solution, the mainboard 2 is arranged near one side of the top of the base 1 to fix the mounting frame 21. The mounting frame 21 is arranged to facilitate the installation of processing equipment.

[0025] A rotating shaft 41 is rotatably connected between the inner walls of the square box 4 and at the center thereof, and a bevel gear 1 42 is fixedly connected to the outer ring of the rotating shaft 41 and close to the inner wall of the square box 4 .

[0026] By adopting the above technical solution, the rotating shaft 41 rotates, thereby causing the fixedly connected bevel gear 1 42 to rotate.

[0027] A motor 43 is fixedly installed at the center of the bottom end of the square box 4 , and the output end of the motor 43 passes through the square box 4 and is fixedly connected to the rotating shaft 41 .

[0028] By adopting the above technical solution, the motor 43 is operated so that the fixedly connected rotating shaft 41 rotates.

[0029] The bottom of the square box 4 is symmetrically fixedly connected with an L-shaped inclined rod 44 near the bevel gear 1 42 . One end of the two L-shaped inclined rods 44 near the bevel gear 1 42 is symmetrically rotatably connected with the bevel gear 2 45 , and the two bevel gears 2 45 are both meshed with the bevel gear 1 42 .

[0030] By adopting the above technical solution, the bevel gear 1 42 rotates, thereby causing the two meshing bevel gears 2 45 to rotate simultaneously.

[0031] One end of the two L-shaped inclined rods 44 away from the bevel gear 1 42 is symmetrically rotatably connected with a threaded sleeve 46 , and one end of the threaded sleeve 46 passes through the L-shaped inclined rods 44 and is fixedly connected to the bevel gear 2 45 .

[0032] By adopting the above technical solution, the two bevel gears 45 rotate simultaneously, so that the two fixedly connected threaded sleeves 46 rotate simultaneously.

[0034] By adopting the above technical solution, the same threaded sleeve 46 rotates at the same time, thereby causing the supporting legs 49 connected by the threaded rotation to move downward.

[0035] Working principle: When the device is in use, first one end of the gantry gear head can be pressed against the clamping plate 13, and then the electric cylinder 12 is operated to make the fixedly connected slide bar 3 slide inside the slide groove 14, and then the two rotatably connected limit wheels 36 are made to contact the other end of the gantry gear head under the cooperation of the rotating block 33, the support plate 2 34 and the M plate 35 which are rotatably connected with the two support plates 1 32, so as to achieve the work of clamping and limiting the gantry gear head, thereby avoiding the displacement of the gantry gear head during processing, and thus solving the problem that it is inconvenient to clamp and fix gantry gear heads of different models when the gantry gear head processing positioning device is in use;

[0036] When the device needs to be moved, the motor 43 can be operated so that the fixedly connected rotating shaft 41 drives the bevel gear 1 42 to rotate, thereby causing the two symmetrically meshing bevel gears 2 45 to rotate at the same time. Then, with the cooperation of the threaded sleeve 46 and the screw 48, the two legs 49 are raised upward at the same time, so that the four moving wheels 11 are in contact with the ground, thereby solving the problem that the gantry gear head processing positioning device has poor flexibility and portability, and is inconvenient for the staff to move the device for work.

[0037] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
