Description
Technical Field
[0001] The utility model relates to the field of spraying, in particular to a multi-head hanger which is convenient for rotary spraying. Background Art
[0002] During the workpiece spraying process, the workpiece needs to be installed on a designated hanger so that it can be sprayed.
[0003] In order to improve the uniformity of spraying, a rotating structure is usually set on the sling to drive the workpiece to rotate at a constant speed during the spraying process. However, the current slings have great shortcomings during use: 1) The rotating shaft and the hanger of the sling, as well as the hooks and hangers, are all fixed by welding, which is prone to positional displacement during the welding process, resulting in unstable suspension of the workpiece during the rotation process, thus affecting the spraying work; 2) Due to the use of welding connection, the positions between the hangers and the hooks are fixed, which leads to the limitation of the use of the sling, that is, it cannot be used for workpieces of different sizes; 3) In order to avoid obstruction between the workpieces, the distance between the hooks is large, which leads to a small number of workpieces on the entire sling, that is, the efficiency of a single spraying is poor. Utility Model Content
[0004] Purpose of the utility model: The purpose of the utility model is to provide a multi-head sling that is convenient for rotary spraying, which solves the problems existing in the sling during rotary spraying.
[0005] Technical solution: The utility model provides a multi-head hanger that is convenient for rotary spraying, including a rotating shaft and a multi-head hanger structure, the multi-head hanger structure has several groups, which are arranged in parallel on the rotating shaft in the vertical direction; wherein, the multi-head hanger structure includes a fixed structure and a hanger assembly, the hanger assembly has several groups, which are arranged in a circular array with the center of the fixed structure as the center, and the hanger assemblies in adjacent multi-head hanger structures are installed in a staggered manner; the hanger assembly includes a bracket, a first hook, and a second hook, the first hook and the second hook have several groups, which are arranged on the bracket at equal intervals; the first hook and the second hook have the same structure, including a first hanging section, an intermediate fixed section, and a second hanging section connected in sequence; the length and angle of the first hanging section and the second hanging section of the first hook are different from the length and angle of the first hanging section and the second hanging section of the second hook. According to the shape and size of the workpiece to be sprayed, a certain number of rack assemblies are selected and installed on the fixed structure. The assembled multi-head rack structure is installed on the rotating shaft in sequence according to the space requirements after the workpiece is hung. After the assembled multi-head hanger is installed on the corresponding rotating structure, the workpiece is hung on the first hook of the rack assembly, the first hanging section of the second hook, and the second hanging section in sequence, so as to facilitate the subsequent rotary spraying. The entire structure is simple. Not only does the staggered installation of the rack assemblies in adjacent multi-head rack structures greatly increase the total number of workpieces on the multi-head hanger during a single spraying, thereby greatly improving the work efficiency, but also the first hook and the second hook with different hanging angles and extension lengths installed on the rack assembly effectively avoid the occurrence of spraying missing due to mutual blocking between workpieces during spraying, thereby improving the yield rate.
[0006] Furthermore, the middle fixing sections of the first hook and the second hook are provided with straight slot holes for installation.
[0007] Furthermore, the fixing structure includes an upper fixing block and a lower fixing seat, and the upper fixing block and the lower fixing seat are arranged in a vertical direction.
[0008] Furthermore, a first countersunk hole is provided at one end of the upper fixing block; a first slot is provided at the other end of the upper fixing block near the side wall, and there are several groups of the first slots, which are arranged in a circular array with the center of the upper fixing block as the center.
[0009] Furthermore, the first slot is a tapered half hole.
[0010] Furthermore, a first threaded hole is provided at one end of the lower fixing seat; a second slot is provided at the other end of the lower fixing seat near the side wall, and the first slots have several groups and are arranged in a circular array with the center of the lower fixing seat as the center; the side wall of the lower fixing seat is also provided with a second countersunk hole arranged oppositely.
[0011] Furthermore, the second slot is a tapered half hole, and a limiting groove is provided on the lower side wall.
[0012] Furthermore, the bracket includes a positioning section and a mounting section which are connected in sequence.
[0013] Furthermore, the positioning section includes a conical column and a positioning block, and the positioning block is arranged on the side of the conical column. The conical column of the positioning section is installed in a conical hole formed by the first clamping groove of the upper fixing block and the second clamping groove of the lower fixing seat, and the diameter of the conical hole gradually decreases from the center to the outside along the upper fixing block, so that the bracket plays a better axial fixing and limiting role, and the positioning block is installed in the limiting groove of the second clamping groove, so that the bracket plays a better radial positioning role.
[0014] Furthermore, the mounting section is provided with a plurality of second threaded holes arranged in parallel for mounting the first hook or the second hook.
[0015] It can be seen from the above technical scheme that the utility model has the following beneficial effects: 1) The multi-head hanger structure and the rotating shaft, the hanger components of the multi-head hanger structure, and the first hook, the second hook and the bracket are all connected with bolts and other fasteners, so that the number of workpieces suspended by the entire multi-head hanger can be adjusted according to the actual product size, that is, it is suitable for the suspension of different types of workpieces and has wide applicability; 2) The staggered installation arrangement of the hanger components in adjacent multi-head hanger structures greatly increases the total number of workpieces on the entire multi-head hanger during a single spraying, thereby greatly improving work efficiency; 3) The hanger components are installed with the first hook and the second hook with different hanging angles and extension lengths, which effectively avoids the occurrence of spraying omissions due to mutual obstruction between workpieces during spraying, thereby improving the yield rate.
