Automatic detection and screening device for hardness of bolt fastening piece

Abstract

The invention discloses an automatic detection and screening device for the hardness of a bolt fastening piece. The automatic detection and screening device comprises a charging part, a rotary table, a workpiece pressing part, a discharging part, a hardness meter and a table, wherein the charging part is fixedly arranged on a swinging platform mounting base; the swinging platform mounting base and the rotary table are mounted on a base of the hardness meter. The continuous and reciprocating motion of the charging part, the workpiece pressing part, the rotary table, the discharging part and the hardness meter realizes continuous multi-point hardness detection and screening of a bolt. According to the automatic detection and screening device, a movable part is driven by an air cylinder and an electromagnet; the control manner is simple and the work is reliable and easy to realize; an adjusting bolt on a driving piece, a gasket on a spring material stopping part, a workpiece positioning sleeve and a rotary baffle are adjusted simply so as to realize hardness detection of the bolts with different specifications and the flexibility is good; meanwhile, the multi-point hardness detection can be carried out on the bolt by controlling the rotary angle of the rotary table so as to meet the requirements of the use of the hardness meter and the hardness detection; the charging part and the discharging part are mounted on a hardness meter worktable and the structure space of the whole machine is compact.

Description

technical field [0001] The invention relates to an automatic hardness detection and screening device in the technical field of manufacturing equipment, in particular to an automatic hardness detection and screening device for bolt fasteners. Background technique [0002] As one of the most widely used mechanical standard parts, there are many manufacturers of bolts, and each manufacturer must pass the certification of the National Fastener Standardization Technical Committee. Each bolt must be tested for hardness according to the requirements of the national standard, and if the hardness is unqualified, it will be rejected. At present, hardness testing is mainly performed manually. Due to the different lengths and diameters of bolts of different specifications, many manufacturers still use manual loading and unloading, manual hardness testing and manual screening, which are inefficient, labor-intensive, error-prone and have potential safety hazards. Therefore, it is very ne...

Problems solved by technology

At present, hardness testing is mainly done manually. Due to the different lengths and diameters of bolts of different specifications, many manufacturers still use manual loading and unloading, manual hardness testing and manual screening, which is inefficient, labor-intensive, error-prone and has potential safety hazards. Therefore, it is very necessary to develop an automatic equipment that can automatically load and unload, automatically detect hardness and automatically screen

[0003] After searching the literature of the prior art, it is found that the Chinese patent application number is: CN201030207628.1, the name is: hardness tester; and the application number is: CN200510115873.8, the name is: hardness tester, these two devices are mainly used for small The batch manual hardness testing mechanism does not have the function of automatic hardness testing for batch products, nor does it have the functions of automatic loading and unloading and hardness screening
