Description
Technical field
The utility model relates to a kind of drive lid drilling processing fixtures, belong to technical field of mechanical processing.
Background technique
It is usually aluminium casting that automobile starter, which drives lid, drives lid casting and needs to carry out drilling processing to it after the completion.Due to driving
Lid structure is in irregular, and has certain radian and gradient, and when carrying out drilling processing to it, fixture is by product
The case where surrounding positions, and this positioning method accuracy is poor, and fixture often will appear loosening in processing, leads to processing dimension easily
There is deviation, inferior rate is larger.On the other hand, existing fixture can only clamp a workpiece, frequent Workpiece clamping every time
Cause working efficiency lower, thus it is necessary to research and develop a kind of fixture of suitable processing drive lid drilling, is easily gone out with solving existing fixture
It now loosens and problem that workpiece clamp loading amount is few.
Summary of the invention
The purpose of this utility model is that: a kind of clamping is provided and stablizes, is easily operated, pine easily occurs to solve existing fixture
Dynamic and workpiece clamp loading amount lacks the drive lid drilling processing fixture of problem.
The technical solution of the utility model is:
A kind of drive lid drilling processing fixture, it is by bottom plate, clamping bar, rotation clamping cylinder, workpiece support and positioning head
It constitutes；It is characterized by: bottom plate is fixed on working plate, by symmetrically arranged rotation clamping cylinder equipped with clamping on bottom plate
Bar；The both ends of rotation clamping cylinder are fixed with workpiece support respectively；Each support base side is respectively arranged with installation fixed block；Peace
Positioning cylinder is fixed on the corresponding bottom plate of dress fixed block, the piston rod end of positioning cylinder is equipped with positioning head；Positioning head and solid
It is coaxial to determine block.
The workpiece support is made of chassis and positioning column, and positioning column is arranged in the centre on chassis.
The positioning column is stepped.
Banking pin is equipped with by spring on the installation fixed block.
The clamping bar is strip, and the both ends of clamping bar are equipped with pressure head.
Utility model has the advantages that
The clamp structure is simple, ingenious in design, drive when work lid be placed on support base it is fixed；Positioning cylinder pushes positioning
Head, banking pin and positioning head fix the flank for driving lid；Clamping bar turns to horizontal position and then pushes, with matching for support base
It closes, lid will be driven and be fixed on positioning seat, mobile and rotation will not be generated；The case where solving existing fixture often and will appear loosening,
Lead to that deviation easily occurs in processing dimension and workpiece clamp loading amount is few, frequent Workpiece clamping causes working efficiency is lower to ask
Topic drives lid use especially suitable for driving lid drilling processing clamping.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the working state schematic representation of the utility model.
In figure: 1, bottom plate, 2, chassis, 3, positioning column, 4, positioning head, 5, positioning cylinder, 6, rotation clamping cylinder, 7, clamping
Bar；8, working plate, 9, installation fixed block, 10, banking pin, 11, pressure head.
Specific embodiment
The drive lid drilling processing fixture is made of bottom plate 1, clamping bar 7, rotation clamping cylinder 6, support base and positioning head 4:
It is fixed with bottom plate 1 on working plate 8, passes through symmetrically arranged rotation clamping cylinder 6 on bottom plate 1 and clamping bar 7 is housed；Rotation clamps
It is fixed with workpiece support respectively on the bottom plate 1 at the both ends of cylinder 6.Workpiece support is made of chassis 2 and positioning column 3, chassis 2
Centre be provided with stair-stepping positioning column 3, workpiece to be located on chassis 2 in clamping.The chassis 2 of each support base
Side is respectively arranged with installation fixed block 9；Installation fixed block 9 is made of mounting bedplate and assembly head, is provided on mounting bedplate
Assembly head, mounting bedplate and assembly head are structure as a whole, and pilot hole is provided on mounting bedplate, solid for the connection with bottom plate 1
It is fixed, it installs and banking pin 10 is equipped with by spring on the assembly head of fixed block 9.It is fixed to be fixed on the corresponding bottom plate 1 of banking pin 10
The piston rod end of position cylinder 5, positioning cylinder 5 is equipped with positioning head 4；Positioning head 4 and the banking pin 10 of installation fixed block 9 are coaxial.
The clamping bar 7 of the drive lid drilling processing fixture is strip, and the both ends of clamping bar 7 are equipped with pressure head 11.
The drive lid drilling processing fixture is first determined its spiral-lock in support base by the inner hole of workpiece when clamping workpiece
Position column 3 on, while make the recess of workpiece be stuck in installation fixed block 9 mounting bedplate on, it is above-mentioned be ready to complete after, starting positioning gas
Cylinder 5, the piston rod of positioning cylinder 5 stretch out, by the cooperation of the positioning head 4 and banking pin 10 of piston rod end by workpiece clamping,
Then starting rotation clamping cylinder 6 makes it through clamping bar 7 and compresses the workpiece on its two end pieces support base；By to complete
At the clamping of workpiece.
The drive lid drilling processing fixture is in workpiece support, installation fixed block 9, positioning cylinder 5 and rotation clamping cylinder 6
Under coordinated, loosening of the workpiece in drilling process can be prevented；Solving fixture in existing processing often will appear loosening
The case where, cause processing dimension deviation easily occur, inferior rate is larger.And existing fixture can only clamp a workpiece every time,
The problem that frequent Workpiece clamping causes working efficiency lower；Lid use is driven especially suitable for driving lid drilling processing clamping.
