Description
Technical Field
[0001] The utility model relates to industrial automated conveying equipment and parts, in particular to a corner piece and a tray thereof, and belongs to the field of automated industry. Background Art
[0002] The conveyor pallet is used in light and medium load situations of the automated pallet conveying system. At present, the conveyor pallet in the form of an aluminum pallet plate placed on a plug-in frame formed by horizontal plug-in is used as an example. The plug-in frame is composed of corner pieces and profiles at four corners through plug-in intervals. The existing corner pieces are split structures, with corner wear blocks installed at the bottom; the number of overall parts is relatively large; the two connecting ends of the corner pieces need to be bolted to the profile with reinforcing columns, and a hole for inserting the reinforcing column is set on the plug connector at one end, and a matching hole needs to be opened on the profile corresponding to the position of the hole.
[0003] The problem with the above-mentioned corner piece structure is that the reinforcing column is set in the profile area; therefore, the profile at the reinforcing column position must bear the impact and friction of the material stopper. Since the profile is made of aluminum alloy, the surface wear resistance of the impact position between the profile and the material stopper is poor and is often easily damaged. Utility Model Content
[0004] In view of the technical problems existing in the above-mentioned corner fittings, the purpose of the utility model is to integrate the corner fittings as a whole and provide a corner fitting and a tray thereof, which adopts the form of an integral corner fitting and greatly reduces the number of parts; the setting position of the reinforcing columns on the corner fittings is optimized and integrated, so that the collision position between the tray and the material stopper is moved to the corner fitting area, avoiding the collision between the original aluminum profile and the material stopper, and the problem of easy damage due to poor wear resistance.
[0005] In order to achieve the above-mentioned purpose, the technical scheme adopted by the utility model is: a corner piece, comprising: an integrated right-angle injection-molded body, wherein the right-angle injection-molded body respectively forms extensions to the outside in mutually perpendicular directions, and the extensions are respectively provided with pairs of plug connectors on the outside, and are plugged with the profiles adjacent to the corner piece through the plug connectors; an integrated corner wear-resistant block is integrated on the lower bottom surface of the right-angle injection-molded body at the right angle; extensions are located on both sides of the corner wear-resistant block, one of the extensions is provided with a positioning pin sleeve connection hole, and the other extension and the body at the corresponding position of the corner wear-resistant block are provided with screw holes, and copper screws are embedded in the screw holes;
[0006] Furthermore, the positioning pin sleeve connection hole on the corner piece is a radial through hole for installing the positioning pin sleeve;
[0007] Further, the extension of the positioning pin sleeve connection hole is set as the first extension of the corner piece, and the extension of the screw hole is set as the second extension of the corner piece;
[0008] Furthermore, the screw hole of the second extension part is a connection hole located on the angle piece and is located at the ends of the two plug connectors; when the plug connector is plugged into the profile, the part that collides with the material stopper is located on the inner side wall and the outer side wall of the second extension part, and does not collide or rub with the profile part, thereby overcoming the defects that the aluminum profile at the reinforcing column position in the traditional angle piece structure bears the impact and friction of the material stopper, and the aluminum alloy surface has poor wear resistance and is often easily damaged;
[0009] Furthermore, the corner piece of the present technical solution is made of plastic as a whole, and the parts that will collide with the material stopper are the inner and outer walls of the second extension part. Below the positioning pin sleeve connecting hole of the first extension part is a half-height avoidance position for making way for the material stopper; and the impact part of the corner piece is made of nylon, which has high wear resistance and is not easy to wear.
[0010] Furthermore, the head ends of the two plug connectors of the first extension portion are arranged with inclined structures at the inner chamfers relative to each other and are arranged symmetrically with each other. The purpose of setting the inclined chamfers here is to facilitate the plug connectors to be quickly and accurately plugged into the profile;
[0011] Furthermore, the head ends of the two plug connectors of the second extension portion are both square-headed;
[0012] Furthermore, each of the plug connectors of the two extended parts of the corner piece is provided with reinforcing ribs, and the internal stress of the plug connector is uniform. When plugged into the profile, the elastic deformation of the plug connector is changed to insert the profile, thereby ensuring self-locking with the profile, while ensuring the strength of the plug connector and the tightness of the fit with the profile. In order to prevent shrinkage and deformation of each plug connector of the two extended parts, a design of uniform wall thickness and tension ribs is adopted.
[0013] Furthermore, a metal sensing patch is integrated on the lower surface of the second extension portion and at a position corresponding to the screw hole to meet the working requirements of the conveyor line operation.
[0014] The pallet adopting the above-mentioned structural corner piece comprises: a pallet support plate and a plug-in frame located at the lower part of the pallet support plate; the plug-in frame comprises four corner pieces and four profiles, and the corner pieces and the profiles are arranged at intervals by plugging to form an integral plug-in frame; the pallet support plate is connected to the plug-in frame by two copper screws and a positioning pin sleeve on each corner piece, so as to realize the reinforcement and positioning of the pallet support plate;
[0015] Furthermore, bolt holes are provided at the four corners of the pallet support plate, and copper screws are used in the bolt holes to fasten the pallet support plate to the corner pieces;
[0016] Furthermore, a corresponding matching hole is provided on the pallet support plate corresponding to the position of the positioning pin sleeve connection hole of the first extension of the corner piece, and a corresponding matching hole is provided on the pallet support plate corresponding to the position of the screw hole of the second extension of the corner piece; the pallet support plate is connected to the plug-in frame in a one-to-one correspondence through the positioning pin sleeve and the copper screw;
[0017] Furthermore, the positioning pin sleeve and the positioning pin sleeve hole are in interference fit;
[0018] Furthermore, the profile is a double-channel rectangular hollow structure, and the double channels are used for plugging with the plug connector of the corner piece.
[0019] The beneficial effects of the utility model are:
[0020] Compared with the traditional corner piece, the collision position between the tray and the material stopper is changed, and the collision between the corner piece and the material stopper is realized. Compared with the traditional method of using profiles to withstand the impact of the material stopper, it has high wear resistance and is not easy to wear;
[0021] The corner fittings adopt an integral structure, with corner wear-resistant blocks, induction gaskets, etc. integrated into the corner fittings, greatly reducing the number of overall parts. At the same time, the positions of the original reinforcement columns of the corner fittings are integrated, and one-piece cast copper screws embedded in the corner fittings are adopted, thereby greatly reducing the number of processes and techniques. It also simplifies the processing procedures and techniques of the profiles, improves efficiency, and reduces delivery time. BRIEF DESCRIPTION OF THE DRAWINGS
