Description

The automatic Rockwell apparatus of mobile frame head
Technical field
This utility model relates to a kind of material hardness detection equipment, in particulars relate to a kind of automatic Rockwell apparatus of mobile frame head.
Background technology
The Rockwell apparatus used in China's material Rockwell hardness detection, is all that detected member is placed on lower table, and workbench is arranged on the upper surface of lower end leading screw, owing to leading screw diameter is smaller, workbench can not be very big, and therefore, user detects the Rockwell hardness of bigger part and cannot be carried out.Owing to leading screw supports whole detected pieces weight, still suffer from Rockwell apparatus 150KG load, cause leading screw carrying the biggest.Especially when carrying out higher detected pieces hardness determination, the testing result of Rockwell hardness will be made a big impact by leading screw with axle sleeve gap.
When using mobile frame head automatic Rockwell hardness timing, detected member has been moved up and down by head with the gap of pressure head, has eliminated leading screw jacking system.Therefore, the lower table area of plane is very big, and bearing capacity is the strongest.User is to complete volume relatively big, during the heaviest detected member detection of weight, it is possible to smoothly complete.Owing to moving up and down of head is moved along two high accuracy line slide rails, overcome the spindle arrangement precision problem end of compared with, improve the accuracy of detection of Rockwell hardness.Easily realize the automatic detection of Rockwell hardness simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of automatic Rockwell apparatus accurate, efficient, durable, applied widely.Mainly solving existing durometer uses screw mandrel workbench to there is the technical problem that cannot detect heavy parts.
Scheme of the present utility model is: a kind of automatic Rockwell apparatus of mobile frame head, including base, fuselage, head, fuselage is fixed on base, it is characterized in that: head is fixed on head jacking system, in two line slide rail fixed main body of head jacking system, every line slide rail is provided with two slide blocks matched, slide block is fixed on the rear end face of head, lifting nut is fixed on head connector, lifting ball screw, loading ball screw and two linear bearings, lifting ball screw lower end connects servo lifting motor output shaft, two polished rods are had in two linear bearings, polished rod upper end connects loading pressing plate, polished rod lower end connects loading motor by loading ball screw, loading unit is fixed on loading ball screw.Fixed main shaft seat on head, measuring staff is set in spindle drum, measuring staff middle-end arranges pressure transducer, pressure transducer lower plane and measuring staff end contact, on pressure transducer, plane contacts with load transfer unit, measuring staff lower end connects pressure head, and measuring staff upper end leans measuring unit, and measuring unit one end connects displacement transducer.
The beneficial effects of the utility model:
Owing to the automatic Rockwell apparatus of mobile frame head uses two line slide rails and ballscrew servomotor, achieve head and move up and down adjustment pressure head and detected member gap, reach head and moved high-precision purpose, thus the accuracy of detection of Rockwell hardness can be significantly increased.Owing to workbench is plane, area is big, space is big, can place the detected member of more volume and weight.Meanwhile, table plane can arrange multiple special fixture, greater area of workbench more can be installed, it is achieved Rockwell hardness fully-automated synthesis.Pressure transducer is arranged on measuring staff, and during loading lever loading, pressure transducer feedback force value is 1:1 output so that sensor force value output accuracy is higher.Loading system uses linear bearing and feed rod coupling, it is achieved loading process minimum friction forces.Loading uses motor and ball screw system so that loading system is more accurate and steady when loading and off-load.The parts precision that the automatic Rockwell apparatus of mobile frame head is used is high, is approved product on market.Therefore, good manufacturability, durability is strong, failure rate is low, quick in manufacturing and designing.

Detailed description of the invention
nullWith reference to Fig. 1、2,A kind of automatic Rockwell apparatus of mobile frame head,Including base 1、Fuselage 15、Head 4,Head is provided with nose cover 14,Fuselage 15 is fixed on base 1,Fuselage has removable rear cover 18,Fuselage is additionally provided with dust cover 16,Head 4 is fixed on head jacking system 3,In 3 two line slide rail 28 fixed main body of head jacking system,Every line slide rail is provided with two slide blocks 27 matched,Slide block 27 is fixed on the rear end face of head 4,Lifting nut 19 is fixed on head connector、Lifting ball screw 23、Loading ball screw 22 and two linear bearings 29,Lifting ball screw 23 lower end connects servo lifting motor 25 output shaft,Two polished rods 30 are had in two linear bearings,Polished rod 30 upper end connects loading pressing plate 17,Polished rod 30 lower end connects loading motor 24 by loading ball screw 22,Loading unit 21 is fixed on loading ball screw 22.Fixed main shaft seat 8 on head, measuring staff 10 is set in spindle drum 8, measuring staff 10 middle-end arranges pressure transducer 7, pressure transducer 7 lower plane and measuring staff 10 end contact, on pressure transducer, 7 planes contact with load transfer unit 9, measuring staff 10 lower end connects pressure head 5, and measuring staff 10 upper end leans measuring unit 11, and measuring unit 11 one end is connected with displacement transducer 12.
Before the work of mobile frame head automatic Rockwell apparatus, detected member 26 is put on workbench on 2, detected member 26 test point alignment protective cover 6 center.Pressing control chamber 31 initiating key, the servo lifting motor 25 in head jacking system 3 is started working.Head 4 is made to do downward movement along line slide rail 28 by lifting ball screw 23.After the protective cover 6 in head 4 contacts with detected member 26, servo lifting motor 25 works on so that servo lifting motor 25 reaches a definite value moment of torsion, and protective cover 6 applies a force value to detected member 26.Servo lifting motor 25 quits work, and is signaled to control chamber 31, and control chamber 31 controls loading unit 21 and starts working.Loading motor 24 starts to rotate, and by the loading ball screw 22 on head connector 20, loading unit 21 does downward movement.Two polished rods 30 connected on loading unit 21 pull the descending power of loading pressing plate 17 to act on loading lever 13.Loading lever 13 will be added load be applied in detected member 26 by load transfer unit 9, pressure transducer 7, measuring staff 10, pressure head 5.When being loaded to 10KG, pressure transducer 7 can send signal.Displacement transducer 12 is started working.When load is added to 150KG, moving down occur in pressure head 5, measuring staff 10, measuring unit 11 above measuring staff 10 will pass to displacement transducer 12 displacement, and the result of measurement is fed back to control chamber 31 by displacement transducer 12, displacement be converted into Rockwell hardness number and show on the panel of control chamber 31.After 150KG guarantor's lotus time completes, loading unit 21 will retract into initial position, and realizes the off-load work of 150KG load.Meanwhile, head jacking system 3 can will move 2MM on movement head 4 so that mobile detected member 26 is convenient.
