Description

Technical Field

[0001] The utility model relates to the technical field of rack processing, in particular to a rack vertical processing positioning device. Background Art

[0002] A rack is a special gear with teeth distributed on a bar-shaped body. Racks are divided into spur racks and helical racks, which are used in pairs with spur gears and helical gears respectively; the tooth profile of a rack is a straight line rather than an involute (it is a plane for the tooth surface), which is equivalent to a cylindrical gear with an infinite pitch circle radius.

[0003] When processing the rack, a positioning device is required to position and fix the rack. In the prior art, when the rack is limited and fixed, the two ends of the rack are clamped and fixed. The rack fixing process is complicated and it is not convenient to quickly fix the rack. In addition, the sizes of racks are different, which makes it inconvenient to position and fix racks of different sizes. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art that the rack fixing process is complicated, it is inconvenient to quickly fix the rack, and the sizes of the racks are different, which makes it inconvenient to position and fix racks of different sizes, and proposes a rack vertical processing positioning device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A rack vertical processing positioning device is designed, including a base, wherein:

[0007] The base is detachably connected with a limiting mechanism for limiting the bottom of the rack, the upper end of the base is fixedly connected with a guide rod, the guide rod is slidably connected with an extrusion plate for fixing the top of the rack, and the upper end of the base is rotatably connected with a first threaded rod for driving the extrusion plate to move in the vertical direction;

[0008] The limiting mechanism comprises a support plate, the support plate is fixed to the base by fixing bolts, and the upper end of the support plate is fixedly connected to the limiting frame.

[0009] Preferably, an anti-wear pad is fixedly connected to the bottom end of the base.

[0010] Preferably, the support plate and the limiting frame are an integral structure.

[0011] Preferably, a storage groove is provided on the base, and a collection rack is slidably connected to the storage groove, and the collection rack is located below the limiting mechanism.

[0012] The utility model provides a rack vertical processing positioning device, which has the following beneficial effects:

[0013] The bottom end of the rack is placed on the upper end of the support plate, and the side of the rack contacts the limit frame, which limits and fixes the rack. The extrusion plate moves downward for a distance and then contacts the upper end of the rack, and squeezes the upper end of the rack. The rack is simply fixed. When limiting racks of different widths, the limiting mechanism is replaced as needed to limit racks of different widths, which is convenient for positioning and fixing racks of different widths.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-2 , a rack vertical processing positioning device, comprising a base 1, wherein:

[0021] The bottom end of the base 1 is fixedly connected with an anti-wear pad, which is a rubber pad. The base 1 is detachably connected with a limiting mechanism 2 for limiting the bottom of the rack. The upper end of the base 1 is fixedly connected with a guide rod 3, and the guide rod 3 is slidably connected with an extrusion plate 4 for fixing the top of the rack. The upper end of the base 1 is rotatably connected with a first threaded rod 5 for driving the extrusion plate 4 to move in the vertical direction. A storage groove is provided on the base 1, and a collection rack 7 is slidably connected to the storage groove. The collection rack 7 is located below the limiting mechanism 2. When the rack is positioned and fixed, The rack is placed on the limiting mechanism 2, and the limiting mechanism 2 limits the bottom of the rack. After the first threaded rod 5 is rotated, the extrusion plate 4 moves downward, and the extrusion plate 4 contacts the upper end of the rack after moving downward for a distance, and squeezes the upper end of the rack to fix the two ends of the rack, so as to position and fix the rack. The rack is simply fixed. When limiting racks of different widths, the limiting mechanism 2 can be detachably fixed, and the limiting mechanism 2 can be replaced as needed to limit racks of different widths, so as to facilitate the positioning and fixing of racks of different widths.

[0022] The limiting mechanism 2 includes a support plate 21, which is fixed to the base 1 by fixing bolts. The upper end of the support plate 21 is fixedly connected to the limiting frame 22. The support plate 21 and the limiting frame 22 are an integrated structure. The bottom end of the rack is placed on the upper end of the support plate 21, and the side of the rack is in contact with the limiting frame 22. The limiting frame 22 limits and fixes the rack, and the rack positioning operation is simple.

[0023] Working process: when positioning and fixing the rack, the bottom end of the rack is placed on the upper end of the support plate 21, and the side of the rack contacts the limit frame 22, and the limit frame 22 limits and fixes the rack. After rotating the first threaded rod 5, the extrusion plate 4 moves downward, and the extrusion plate 4 contacts the upper end of the rack after moving downward for a distance, and squeezes the upper end of the rack to fix the two ends of the rack, thereby positioning and fixing the rack. The rack is simply fixed. When limiting racks of different widths, since the limiting mechanism 2 is detachable and fixed, the limiting mechanism 2 can be replaced as needed to limit racks of different widths, which is convenient for positioning and fixing racks of different widths.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
