The nut check detection device of the multi-functional testing machine of pruner blade
Technical field
This utility model relates to detecting device technique field, is especially the nut check detection device of a kind of multi-functional testing machine of pruner blade.
Background technology
Current pruner blade generally comprises one piece of press strip, two pieces of blades and multiple screw bolt and nut, it is equipped with multiple elongated hole on two pieces of blades, two pieces of blade stack merge and are located at the front of press strip, the end of every bolt through on the corresponding up and down elongated hole of two pieces of blades and press strip by screwing with the nut being positioned at the press strip back side, being additionally provided with pad between bolt head and blade, the screw portion of the bolt being positioned at two pieces of blade elongated holes is socketed with axle sleeve.After the assembling of this blade, need to detect whether to screw to the nut after assembling, and typically all use manual method to detect at present, so workload and work efficiency is relatively low, and manual operations cannot accurately detect the size of frictional force, there is certain risk, the disqualification rate reducing product is higher.
Utility model content
The technical problems to be solved in the utility model is to provide and a kind of uses equipment Inspection, can increase the nut check detection device of the multi-functional testing machine of pruner blade of workload and work efficiency, reduction disqualification rate.
The technical solution of the utility model is to provide the nut check detection device of a kind of multi-functional testing machine of pruner blade with following structure, and it includes framework, cabinet, workbench, display screen, master controller;Described framework is end to end fixing by underframe, top frame and four root posts, described cabinet is positioned at the bottom of framework, described workbench is positioned at the middle part of framework, described workbench is provided with the fixture of fixturing blade, described master controller is located in cabinet, described display location, outside the top sidewall of framework, is additionally provided with many groups of sleeves that can match, connecting rod, motors with the nut on the bolt being tightened on blade below described workbench;The bottom of described sleeve is gear, the spur rack that one end of described connecting rod can be engaged with the gear of sleeve, and the other end of described connecting rod engages with the output shaft gear of motor and is connected, and described motor electrically connects with master controller.
The top of described sleeve is provided with inner hexagonal hole.
This utility model it also include that mounting seat, the middle part of described sleeve are rotatably connected in the hole of mounting seat by bearing.
After using above structure, this utility model has the advantage that the rotational band by motor is dynamically connected bar transverse shifting, connecting rod band moving sleeve rotates, sleeve and nut are if screwing, then sleeve does not rotates, motor has certain load, otherwise then rotate, then the load reduction of motor, as long as the curent change of master controller detection motor, just can determine that motor be loaded with diminish, then can determine that nut does not screws, otherwise then for screwing, so use equipment Inspection, detect simple and reliable property good, workload and work efficiency, reduction disqualification rate can be increased.
As improvement, the top of described sleeve is provided with inner hexagonal hole, can embed with nut and coordinate.
As improvement, this utility model it also include that mounting seat, the middle part of described sleeve are rotatably connected in the hole of mounting seat by bearing, make sleeve rotate relatively reliable.

Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the nut check detection device of the multi-functional testing machine of pruner blade of the present utility model, it includes framework 1, cabinet 2, workbench 3, display screen 4, master controller;Described framework 1 is end to end fixing by underframe, top frame and four root posts, described cabinet 2 is positioned at the bottom of framework 1, described workbench 3 is positioned at the middle part of framework 1, described workbench 3 is provided with the fixture of fixturing blade, described master controller is located in cabinet 2, described display screen 4 is positioned at outside the top sidewall of framework 1, is additionally provided with many groups of sleeves 7 that can match with the nut 6 on the bolt 5 being tightened on blade, connecting rod 8, motors 9 below described workbench 3;The bottom of described sleeve 7 is gear, the spur rack that one end of described connecting rod 8 can be engaged with the gear of sleeve 7, and the other end of described connecting rod 8 engages with the output shaft gear of motor 9 and is connected, and described motor 9 electrically connects with master controller.Be dynamically connected bar transverse shifting by the rotational band of motor, connecting rod band moving sleeve rotates, sleeve with nut if screwing, then sleeve does not rotates, motor has certain load, otherwise then rotates, then the load reduction of motor, as long as master controller detect motor be loaded with diminish, then can determine that nut does not screws, otherwise then for screwing, so use equipment Inspection, detect simple and reliable property good, workload and work efficiency, reduction disqualification rate can be increased.
The top of described sleeve 7 is provided with inner hexagonal hole.
The nut check detection device of the multi-functional testing machine of pruner blade of the present utility model, it also includes that mounting seat 10, the middle part of described sleeve 7 are rotatably connected in the hole of mounting seat 10 by bearing.
