Description
Technical field
This utility model relates to field of machining and machinebuilding technology, particularly relates to a kind of back reaction rod support and connecting shaft assembly drilling tool.
Background technology
At present in machine industry, the mode in the processing hole that we are common is positioned by datum level or datum hole and realizes.But precondition is datum level and the axis with hole to be processed often exists vertical relation, and datum hole often exists parallel relation with the axis in hole to be processed.If the axis in hole to be processed is parallel with datum level, vertical with datum hole, arise that a difficult problem for bad location.Thus, for satisfied remodeling and the demand of new-product development, the bottleneck operation solved during vehicle bridge produces has become problem demanding prompt solution.
Utility model content
The purpose of this utility model there is provided a kind of back reaction rod support and connecting shaft assembly drilling tool, it is intended to solve when the axis processing hole parallel with datum level vertical with datum hole axis time bad location a difficult problem.
A kind of back reaction rod support and connecting shaft assembly drilling tool, including floor pan assembly, L-shaped bushing plate assembly and V-block assembly；Described L-shaped bushing plate assembly includes that location-plate and bushing plate, described bushing plate are fixed on location-plate；Described V-block assembly includes that V-block and brake pad, described brake pad are fixed on V-block, and described V-block is fixed on floor pan assembly.
Being provided with locating dowel on described location-plate, described locating dowel is inserted in the hole that workpiece is machined, makes L-shaped bushing plate assembly workpiece pressing by fastening nut.
Described locating dowel is arranged on location-plate by spot welding.
Stud with drill bushing on described bushing plate, be interference fit between described bushing plate and drill bushing.
Described bushing plate is fixed on location-plate by screw and alignment pin.
Spring washer also it is lined with on described screw.
Described brake pad is fixed by screws on V-block.
Described V-block is fixed by screws on floor pan assembly.
Bushing plate uses modifier treatment to 25～30HRC.
Described locating dowel takes suitable heat treatment to 45～50HRC at the location of workpiece.
Operational approach of the present utility model: V-block is arranged on floor pan assembly by screw；By screw, brake pad is fixed on V-block；By screw, spring washer, alignment pin, bushing plate is arranged on location-plate；Locating dowel is arranged on the bushing plate assembly assembled, improves stability by spot welding；Workpiece is placed on V-block assembly location, inserts locating dowel in the machined hole of workpiece, fastening nut, described L-shaped bushing plate assembly workpiece pressing；After having positioned, unclamp nut, extract locating dowel out and just can be lifted up together with described L-shaped bushing plate assembly, facilitate workpiece loading and unloading.
Advantageous Effects of the present utility model: parallel datum level and vertical reference hole are converted into our common processing hole by V-block with L-shaped bushing plate and position mode by this utility model, it is ensured that the position relationship in hole, also improve the precision of processing；Floor pan assembly is provided with coarse positioning location-plate, and fast and easy positions；Equipped with brake pad on V-block, frock service life can be extended with protective tooling main body, and can change at any time, reduce integrated tooling maintenance rate；By brake pad heat treatment 40～45HRC, improving its wearability, bushing plate uses modifier treatment to 25～30HRC, and comprehensive mechanical performance is excellent.This utility model simple in construction, economy and durability, convenient mounting and clamping, registration, solve the bottleneck operation during vehicle bridge produces, improve product quality and work efficiency.
