Description
Technical field
Processing and manufacturing field is the utility model is related to, lathe assembly technology used tool, is specifically leading screw mounting technology
The instrument that driving torque continuously detects.
Background technology
Leading screw installation is the important component of Machine Manufacture industry, and leading screw installation quality quality directly affects the essence of lathe
Index is spent, criterion and quantity assembling link can not only stablize lathe assembling quality, also help batch production and improve lathe assembling effect
Rate.
It is currently to be completed jointly using a pull and push dynamometer and the dedicated wire roller that can be installed to leading screw drive end
The test of leading screw driving torque, the pull and push dynamometer is compact to design, and appearance and size is moderate, and energy clamping is in various forms and the quilt of size
Survey on pull rod, loading peak value and continuous loading can be tested, easy to use, the items precision when a certain section of leading screw is instantaneously detected
And index can meet test request.But the set detection instrument is by steel wire length, wire roller size and detected leading screw
Effect length, stable detection cannot be carried out continuously to leading screw whole process, and every section of leading screw test needs are readjusted, and should
If pull and push dynamometer extends steel wire without in line with wire roller, then will be unable to obtain correct loading value when testing, because
The application range of this technology is very restricted, and can only be used as sampling observation project.
The content of the invention
The purpose of this utility model is to provide a kind of hand-operated tools continuously detected for leading screw assembling moment of torsion so that digital display
Moment of torsion needed for the driving of torque meter whole process real-time display leading screw, substantially reduces the detection time of leading screw driving torque.
A kind of hand-operated tools continuously detected for leading screw assembling moment of torsion of the utility model, including crank head, rocking arm, digital display
Torque meter, it is characterised in that：Spring pocket is installed in crank head large diameter hole, is pre-positioned with spring pocket holding screw, tested leading screw is inserted
Enter in spring pocket, be fastenedly connected with hexagon socket cap head screw, crank head miner diameter end is connected with connecting rod one end, is tight with connecting rod
Determine screw to fix, the Digital-display torque table square head insertion connecting rod other end, driving end and the Digital-display torque other end are horizontal fixed；Shake
Arm one end fastens assembly wrench head by hexagon-headed bolt and packing ring and is used as leading screw drive shaft end, rocking arm other end right angle setting
Handle external member；Artificial at the uniform velocity continuous crank handle external member, reads Digital-display torque table numerical value, after whole process detection leading screw installation immediately
Required driving torque.
The marked improvement of the design is：Because employing Digital-display torque table, so as to meet whole process manually to leading screw performance
The requirement of the higher of test；Avoid the leading screw driving torsion for being only capable of the test a certain section of leading screw or a bit of length in the prior art
The problem of square, and measuring accuracy is higher；The leading screw installation crank head and spring pocket of the present invention is socket type structure, diameter of bore
It is consistent with the design of lead screw shaft outside diameter, it is simple and reliable for structure for quickly with testing leading screw locking positioning, and make mounting and adjusting very square
Just；It is same axis that leading screw, which installs crank head with Digital-display torque table, tested leading screw and the crank handle centre of gyration, surveys data
Actual value would not be deviateed.Will be right in the prior art by steel wire length, wire roller size and detected leading screw effect length
Leading screw whole process cannot be carried out continuously stable detection, be designed to convenient for disassembly and assembly by manually at the uniform velocity crank handle so that Digital-display torque
Moment of torsion needed for the driving of table whole process real-time display leading screw, substantially reduces the detection time of leading screw driving torque, meets leading screw torsion
Square requirement, test condition and operating mode are more in line with actual leading screw actual use situation, improve efficiency of assembling.
The beneficial effects of the utility model：By simple hand, it can be achieved that detection to leading screw installation quality, basic solution
It is certainly crucial to assemble the problem of link detection means is insufficient, prevent the generation of leading screw quality problems, improve efficiency of assembling.
