Description

Technical Field

[0001] The utility model relates to the technical field of nut positioning, in particular to a novel nut lifting and positioning mechanism. Background Art

[0002] A nut is a nut that is screwed together with a bolt or screw for fastening. It is a component that all manufacturing machinery must use. According to the different materials, it is divided into several major types, such as carbon steel, stainless steel, non-ferrous metals (such as copper), etc. The types of nuts include hexagonal thin nuts, hexagonal thick nuts, flange nuts, butterfly nuts, cap nuts, etc.

[0003] The nuts are loaded by a nut lifter and then transported to the next step for use by a conveyor belt. When loading the flange nuts, the contact surface on one side is larger and the installation direction is different. Most of the existing nut lifters can only lift the nuts, which makes it inconvenient to locate the direction of the nuts. As a result, the direction of the nuts needs to be adjusted during subsequent use, affecting work efficiency. Utility Model Content

[0007] Through the above technical solution, the nut is rolled downward through the inclined groove, and the contact surface of the flange nut can enter the interior of the through groove. The push plate is pushed by the electric telescopic rod to remove the contact surface of the flange nut from the groove.

[0008] As a further improvement of the above scheme, one end of the electric telescopic rod away from the limit plate is fixedly connected to the inner wall of the mounting frame, the number of the electric telescopic rods is two, the two electric telescopic rods are symmetrically distributed with the mounting frame as the center, and the surface of the limit plate is slidably connected to the inner wall of the through groove.

[0011] Through the above technical solution, the extension plate is pulled upward by the long-stroke cylinder, so that the extension plate drives the lifting plate to move upward, thereby lifting the nut upward.

[0012] As a further improvement of the above solution, the number of the mounting plates is set to two, and one end of the two mounting plates close to each other is fixedly connected to the surface of the placement rack.

[0013] Through the above technical solution, the long-stroke cylinder can be easily installed and fixed through the mounting plate.

[0017] Through the above technical solution, the push plate is moved downward by pushing the electric push rod downward.

[0018] As a further improvement of the above solution, the number of the fixing plates is set to two, and the ends of the two fixing plates close to each other are fixedly connected to the inner wall of the placement rack, and the number of the electric push rods corresponds to the number of the fixing plates.

[0019] Through the above technical solution, the two electric push rods improve the stability of the push plate when it moves.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The utility model provides a placement rack, a through slot, a long-stroke cylinder, a lifting plate, an electric push rod and a push plate. Specifically, when the lifting plate moves to the through slot position, the contact surface of the nut in the positive direction will enter the interior of the through slot, and the contact surface in the reverse direction will not enter the interior of the through slot, and the contact surface will exceed the length of the push plate. At this time, the electric push rod pushes downward to move the push plate downward, and pushes away the nuts whose contact surfaces exceed the push plate, so that the lifted nuts are all on the front side, avoiding subsequent adjustment of the nut direction, thereby improving work efficiency.

[0022] The utility model provides an electric telescopic rod, a limit plate, a long-stroke cylinder and a lifting plate. Specifically, the electric telescopic rod pushes the limit plate to move on the inner wall of the through groove, so that the nut whose contact surface is located inside the through groove is pushed outward, and then the long-stroke cylinder pushes the lifting plate upward to the top of the placement rack. The nut will be unloaded along the inclined surface of the lifting plate, which is convenient for unloading the nut and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] One end of the electric telescopic rod 105 away from the limiting plate 103 is fixedly connected to the inner wall of the mounting frame 104. There are two electric telescopic rods 105, which are symmetrically distributed around the mounting frame 104. The surface of the limiting plate 103 is slidably connected to the inner wall of the through groove 102.

[0034] The lifting mechanism 2 includes a mounting plate 201, a long-stroke cylinder 202 is fixedly connected to the bottom of the mounting plate 201, an extension plate 203 is fixedly connected to the bottom of the long-stroke cylinder 202, and a lifting plate 204 is fixedly connected to the left end of the extension plate 203. By starting the long-stroke cylinder 202, the long-stroke cylinder 202 drives the extension plate 203 to move upward, so that the lifting plate 204 slides upward on the inner wall of the slide groove 108, so that the nut moves upward.

[0035] There are two mounting plates 201 , and one end of the two mounting plates 201 close to each other is fixedly connected to the surface of the placement rack 101 .

[0036] There are two long-stroke cylinders 202, which are symmetrically distributed around the placement rack 101. The surface of the lifting plate 204 is slidingly connected to the inner wall of the slide groove 108 and extends to the inside of the inclined groove 106.
