Background technology
J type lock transfers device to be applied to main vehicle 22 types, the 25 type bus brake systems system of current rail operation, and annual nearly 1000 band J type locks transfer the passenger vehicle of device to carry out the A4 maintenance.J type lock in the repair in shop specification requirement after the regulation maintenance transfers the device performance to meet design requirement, and must decompose maintenance during maintenance.
In maintenance process, because the piston spring stiffness coefficient K in the sleeve is bigger, and be not equipped with the tooling device that J type lock is transferred the special-purpose assembling of device, therefore cause the inspection operation personnel to transfer the piston of device to form and do not take out maintenance J type lock.So not only cause the maintainer not transfer the requirement of device standard upkeep operation guiding book to overhaul according to J type lock; Also cause J type lock to transfer the internal piston of device not obtain sound cleaning and maintenance, reduced the repair quality of J type lock accent device largely.
Summary of the invention
The utility model has overcome shortcoming of the prior art; Provide a kind of lock to transfer the device piston to decompose assembler; Having solved J type lock transfers the device piston spring from the ratchet box, to solve and compresses spring and get into ratchet box and stable problem; The maintainer can be formed piston carry out secondary and decompose completely and carry out overhauling carefully comprehensively, promoted completely thereby make on the repair quality.Simultaneously, the utility model makes the maintenance mechanization degree be improved, thus make the maintenance worker reduced man-hour, improved operating efficiency and and reduced the labour, also just improved the overhaul efficiency and the repair quality of enterprise.
The technical scheme of the utility model is: a kind of lock transfers the device piston to decompose assembler; Transfer device ratchet box fixture, piston propeller, propeller slide rail, nut, helical screw, helical screw connection gear, motor connection gear, motor to form by frame, lock; Said lock transfers device ratchet box fixture to be fixed on the side of frame; Piston propeller, propeller slide rail, nut are connected as a single entity through welding; The motor connection gear is connected with motor; And with the helical screw connection gear engagement that is installed in the frame opposite side, be installed on the frame through bearing with an end of the helical screw of nut engagement, the helical screw other end is installed on the motor connection gear.
For movement locus fixing and constant compression piston process medi-spring; Prevent the circular runout that spring causes because of unbalance stress; Spring compression track tube also is installed on the frame; Spring compression track tube is combined by dismountable two semicircular cylinders, a side of spring compression track tube two semicircular cylinders by dismountable loose-leaf through screw fixedly opposite side fix by contiguous block, one of them semicircular cylinder is welded on the frame through the channel-section steel of U-shaped.
In order to amplify the torque and the required rotating speed of adjustable screw screw mandrel of motor output, can also set up one or more groups train of reduction gears between helical screw connection gear, the motor connection gear.
Motor can be selected threephase asynchronous for use, and adopts PLC to control the motor rotating, can realize the back and forth movement of nut on helical screw like this.
Compared with prior art; The utility model solution J type lock is transferred the device piston spring from the ratchet box, to solve and is compressed spring and gets into ratchet box and stable problem; The maintainer can be formed piston carry out secondary and decompose completely and carry out overhauling carefully comprehensively, promoted completely thereby make on the repair quality; Improve the required level of service of enterprise simultaneously, make the maintenance mechanization degree be improved, thereby make the maintenance worker reduced man-hour, improved operating efficiency and and reduced the labour, also just improved the overhaul efficiency and the repair quality of enterprise.
Description of drawings
The utility model will explain through example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the front elevational schematic of the utility model;
Fig. 2 is the schematic top plan view of the utility model;
Fig. 3 is the A-A cutaway view of the utility model.
The specific embodiment
A kind of lock transfers the device piston to decompose assembler; Like Fig. 1, Fig. 2 and shown in Figure 3; Comprise: lock is transferred device ratchet box fixture 1, spring compression track tube 2, piston propeller 3, propeller slide rail 4, nut 5, helical screw 6, helical screw connection gear 7, motor connection gear 8, motor 9, frame 10, channel-section steel 11, loose-leaf 12, screw 13, contiguous block 14 etc., wherein:
A kind of lock transfers the device piston to decompose assembler; Transfer device ratchet box fixture 1, piston propeller 3, propeller slide rail 4, nut 5, helical screw 6, helical screw connection gear 7, motor connection gear 8, motor 9 to form by frame 10, lock; Said lock transfers device ratchet box fixture 1 to be fixed on the side of frame; Piston propeller 3, propeller slide rail 4, nut 5 are connected as a single entity through welding; Motor connection gear 8 is connected with motor 9; And with the helical screw connection gear that is installed in frame 10 opposite sides 7 engagement, be installed on the frame 10 through bearing with an end of the helical screw 6 of nut 5 engagements, helical screw 6 other ends are installed on the motor connection gear 8.
For movement locus fixing and constant compression piston process medi-spring; Prevent the circular runout that spring causes because of unbalance stress; Spring compression track tube 2 is installed on the frame 10; Spring compression track tube 2 is combined by dismountable two semicircular cylinders; One side of 2 liang of semicircular cylinders of spring compression track tube is fixing through screw 13 by dismountable loose-leaf 11, and opposite side is fixing by contiguous block 12, and the channel-section steel 11 of one of them semicircular cylinder through U-shaped is welded on the frame 10 position of transferring device ratchet box fixture 1 near lock.
When lock transfers the device piston to decompose the assembler use; Utilize lock to transfer the ratchet box that three bolts hole and three bolts hole on the ratchet box on the device ratchet box fixture 1 will be to be disassembled to fix; Start motor 9 through 9 rotatings of PLC control motor; Power is delivered to helical screw 6 through motor connection gear 8, helical screw connection gear 7; Because piston propeller 3, propeller slide rail 4, nut 5 are connected as a single entity through welding, the back and forth movement of nut 5 on helical screw 6 makes piston propeller 3 can realize back and forth movement equally, can from the ratchet box, solve the compression spring.Propeller slide rail 4 fixed piston propellers 3 laterally, track longitudinally, alleviate because the moment of resistance that the bounce of piston causes for nut 5.
Through mounting spring on frame compression track tube 2, can fix the movement locus with constant compression piston process medi-spring, prevent the circular runout that spring causes because of unbalance stress.
For the required rotating speed of the torque of amplifying motor 9 output and adjustable screw screw mandrel 6, can also set up one or more groups train of reduction gears between helical screw connection gear 7, the motor connection gear 8.
