AI Technical Summary
Because the U-shaped double-sided output is large with the iron core linear motor, the equipment installed through the screw has a large force on the screw when it moves, and the screw wear and looseness is prone to occur after long-term use.
A U-shaped double-sided output iron core linear motor is designed. By setting a convex rod on the mounting plate and installing a contact assembly on the convex rod, the contact assembly is made to resist the front and rear sides of the device, avoiding the device moving only through the screws, thereby reducing the wear of the screws.
The equipment is pushed by contact components, which avoids the direct effect of the screw driving the equipment to move, reduces the wear of the screw, extends the service life of the screw, and avoids the problem of screw looseness.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0019] As mentioned in the background art, in view of the large output force in the prior art, when the device installed by screws moves, the force on the screws is large. After long-term use, the screws are prone to wear, and in severe cases, the screws are prone to looseness. The present utility model provides a U-shaped double-sided output iron-core linear motor.
[0020] Embodiment 1
[0021] Referring to Figure 1 , a U-shaped double-sided output iron-core linear motor includes a guide rail 1 with a linear motor. A slider 2 is slidably connected to the guide rail 1, and a mounting plate 3 is provided on the top of the slider 2. A screw hole 4 is provided on the mounting plate 3. The device is placed on the mounting plate 3 and fixed to the screw hole 4 by screws.
[0022] Convex rods 5 are provided on both the front and rear sides of the top of the mounting plate 3, and the length direction of the guide rail 1 is along the front-rear direction. The linear motor drives the slider 2 to move along the guide rail 1, so that the mounting plate 3 drives the device to move through the screws.
[0023] Both convex rods 5 on both sides are connected to the contact assembly, and the contact assembly is in contact with the front and rear sides of the device mounted on the mounting plate 3 respectively. The contact assembly abuts against the front and rear sides of the device, so that when the mounting plate 3 drives the device to move through the screws, the contact assembly can push the device, avoiding driving the device to move only by screws and reducing the wear of the screws.
[0024] The contact assembly includes two movable plates 6. The two movable plates 6 respectively penetrate through the two convex rods 5 in the front-rear direction. Connecting frames 7 are provided at the mutually remote ends of the two convex rods 5. Screws 8 are rotatably connected to the two movable plates 6. The two screws 8 respectively penetrate through the two connecting frames 7. The screws 8 rotate on the connecting frames 7, so that the movable plates 6 contact the outer wall of the device after being guided by the convex rods 5.
[0025] In order that the rotation of the screws 8 does not drive the movable plates 6 to rotate, but only drives the movable plates 6 to move in the front-rear direction, the two screws 8 are rotatably connected to the two movable plates 6 through bearings.
[0026] In order to facilitate the rotation of the screws 8, handwheels 9 are provided at the mutually remote ends of the two screws 8.
[0027] Embodiment 2
[0028] Referring to Figures 1 to 2, the contact assembly includes two movable rods 10. Both of the two movable rods 10 are located between the opposite sides of the two convex rods 5. Electric telescopic rods 11 are connected to both of the two movable rods 10. The electric telescopic rods 11 are powered and controlled by the prior art. The output ends of the electric telescopic rods 11 penetrate through the convex rods 5 and are connected to the movable rods 10. Mounting brackets 12 are provided at the mutually remote ends of the two convex rods 5, and the two electric telescopic rods 11 are respectively arranged on the two mounting brackets 12. The electric telescopic rods 11 drive the movable rods 10 to move in the front-back direction, so that the outer wall of the device can be quickly contacted, which is more labor-saving.
[0029] The rest of the structure is the same as that of Embodiment 1.
[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
