Description
Technical field
The utility model relates to motor car bogie more particularly to a kind of motor car bogie longitudinal beam numerical control boring tools.
Background technique
Longitudinal beam is the important component of motor car bogie, it is connected to the weight such as the damper of bogie, power motor
Component is wanted, quality directly affects the performance of entire motor car bogie and the normal operation of vehicle and safety.
Traditional motor car bogie longitudinal beam is needed before numerical control boring using multiple vertical top motor-car to be processed
Bogie longitudinal beam is propped up, then with scriber or height gauge according to the reference line finished in advance by entire profile centering, to be processed
Motor car bogie longitudinal beam positioned.This traditional motor car bogie longitudinal beam localization method has repeatability, operation
Complicated cumbersome, time-consuming and laborious, processing efficiency is low, and positioning is insecure, is easy to loosen, causes Product Precision low, seriously affect production
Product service performance and safety.
Summary of the invention
The utility model is in order to solve the above-mentioned technical problem, to provide a kind of motor car bogie longitudinal beam numerical control boring tool,
Its is easy to operate, time saving and energy saving, can be improved processing efficiency, firm position, improves Product Precision, guarantee product service performance and
Safety.
The technical solution of the utility model is:
Motor car bogie longitudinal beam numerical control boring tool, including bottom plate, are characterized in that on the left of bottom plate and L-type are arranged
The fastening bolt extended in left-right direction is arranged on the left side of L-type positioning plate for positioning plate；In plate top surface front, left and right cloth is set
The second parallels of left and right arrangement is arranged at plate top surface rear portion in the first parallels set, positioned at the first parallels of right end and all
Vertical pull rod is respectively set on second parallels, pull rod top is connected through a screw thread locking nut, and is located on the pull rod
Pressing plate is cased with below locking nut.
Further preferably, lateral side opening is equipped on the pressing plate, pressing plate is by cross side opening sleeve in the pull rod
On, without dismantling nut, pressing plate is convenient for disassembly and assembly.
Further preferably, first parallels is cylindric.
It further preferably, is flat column positioned at the first parallels of right end.
Further preferably, second parallels is flat column.
The beneficial effects of the utility model are:
Since the L-type positioning plate on the left of bottom plate is arranged in, be arranged in L-type positioning plate the left side extend in left-right direction it is tight
Fixing bolt limits the freedom degree of Product Level；Due to be arranged on bottom plate the first parallels, the second parallels, be located at right end
The first parallels and all second parallels on respectively by pull rod be arranged pressing plate, define the freedom degree of product vertical direction；
Its is easy to operate, time saving and energy saving, improves processing efficiency, and firm position, improves Product Precision, ensure that the use of product
Performance and safety.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the utility model and motor car bogie longitudinal beam assembly structure figure；
In figure: 1- bottom plate, 2-L type positioning plate, 3- fastening bolt, the first parallels of 4-, the second parallels of 5-, 6- pull rod, 7- lock
Tight nut, 8- pressing plate, 801- transverse direction side opening.
Specific embodiment
As shown in Figure 1 and Figure 2, motor car bogie longitudinal beam numerical control boring tool, including bottom plate 1, pass through spiral shell on the left of bottom plate 1
Bolt installs L-type positioning plate 2, and the fastening bolt 3 extended in left-right direction is installed on the left side of L-type positioning plate 2；In 1 top surface of bottom plate
Front installs the first parallels 4 of four pieces or so arrangements by bolt, and the first parallels 4 positioned at right end is flat column, excess-three
The first parallels of block 4 be it is cylindric, two pieces or so the second parallels 5 arranged are installed by bolt at 1 top surface rear portion of bottom plate, described the
Two parallels 5 are flat column, are installed vertically by screw thread respectively on the first parallels 4 of right end and two piece of second parallels 5
Pull rod 6,6 top of pull rod are connected through a screw thread locking nut 7, and are located at below locking nut 7 on the pull rod 6 and are cased with pressing plate
8, lateral side opening 801 is equipped on the pressing plate 8, pressing plate 8 passes through lateral 801 sets of side opening on the pull rod 6.
When positioning operation, bottom plate 1 is mounted by means of bolts on numerical control borer first, motor-car to be processed is turned to
Frame longitudinal direction beam seat passes through pull rod 6 on motor car bogie longitudinal beam from bottom to top on the first parallels 4 and the second parallels 5
Corresponding mounting hole；Then motor car bogie longitudinal beam left end acted against into the left side of L-type positioning plate 2, indulge motor car bogie
The front that L-type positioning plate 2 is acted against to beam front end is connected motor car bogie longitudinal beam and L-type positioning plate 2 by fastening bolt 3
Connect fixation；Pressing plate 8 is passed through into lateral 801 sets of side opening on pull rod 6 again, pressing plate 8 is made to be located at motor car bogie longitudinal beam and lock
Between tight nut 7, each locking nut 7 is locked, by motor car bogie longitudinal direction strong fix in the motor car bogie longitudinal beam numerical control
Boring tool；Operation finally is processed to motor car bogie longitudinal beam.
The above are only specific embodiments of the present invention, is not intended to limit the utility model, for this field
Technical staff for, various modifications and changes may be made to the present invention.Within the spirit and principle of the utility model,
Any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
