Detailed description of the invention
Describe the preferred technical solution of the present invention below in conjunction with the accompanying drawings in detail.
It is exclusively used in, as it is shown in figure 1, a kind of, the installation fixture that workpiece bottom boring is levelling, including frock clamping platform 1, is positioned at frock clamping platform 1
Bottom is provided with the frame structure 2 for integrated support, and frame structure 2 is highly usually no more than 50cm, platen to be adapted for mount on
On, frame structure 2 provides stronger support force, it is simple to processing, arranges and have some through holes between frock clamping platform 1 and frame structure 2
Via layer 3, through each through hole in via layer 3, expansion link 4 is set, the passage that via layer 3 is slided as expansion link 4, typically want
There is certain thickness to ensure, to strengthen the restriction of the sliding position to expansion link 4, prevent expansion link 4 from rocking and distorting；At some expansion links 4
Bottom spring seat 5 is set, described spring seat 5 includes some tubular structures being vertically arranged, each tubular structure corresponding above it one
Individual expansion link 4, tubular structure and the relative populations of expansion link 4 to keep consistent, and man-to-man bearing function can effectively be shared on workpiece each
The gravity of point, to reach relative balance, usual frock clamping platform 1 be square, then select 4*4, and 5*5,6*6 determine as required,
Being both provided with spring body 6 in each tubular structure, the stretching of each spring body 6 must be consistent with compression holding capacity；At frock clamping platform 1
Being provided above the lifting pressing mechanism for pressing workpiece bottom, lifting pressing mechanism is vertical with frock clamping platform 1, has up-down adjustment function,
Lifting pressing mechanism acts on inversion and is arranged on the workpiece bottom on some expansion links 4, and the workpiece bottom that can adjust workpiece further works relatively
The depth of parallelism of platform.
Further, described frock clamping platform 1 has flexible clamping device, described expansion link 4 flexible maximum height and minimum altitude
Being above the height of frock clamping platform 1, to ensure that workpiece will not touch frock clamping platform 1, lose regulatory function, described expansion link 4 is stretched
The maximum height of contracting and the difference of minimum altitude are less than the clamping face longitudinal length of flexible clamping device, and this can be effectively ensured the stability of clamping workpiece.
Further, described flexible clamping device includes that base stop part 7, the preposition stopper portions 8 with screw and connection have screw rod
Mobile retained part 9, mobile retained part 9 is moved between preposition stopper portions 8 and base stop part 7 by screw rod, mobile clamping
Part 9 is the main component regulating clamping width, is adapted to the clamping of most of workpiece；The edge of described frock clamping platform 1 has can
Driving preposition stopper portions 8 to carry out the block elevating mechanism of upper-lower height position adjustments, preposition stopper portions 8 is arranged on block elevating mechanism,
Till block elevating mechanism can actively regulate the relative altitude that mobile retained part 9 compresses, in order to avoid touching expansion link 4 during clamping, it is also adapted to
The clamping of the bigger workpiece of height dimension.
Further, described lifting pressing mechanism includes that declining pressing workpiece bottom is crowded for levelling pressing part 10, pressing part 10
The part of pressure workpiece bottom, for levelling, it is parallel that raising bottom surface presses the part of workpiece with the depth of parallelism pressing part 10 of frock clamping platform 1
In the plane of frock clamping platform 1, arranging liftable pillar construction in frock clamping platform 1 edge, described pillar construction is fixing connects pressing
Part 10, pillar construction realizes pressing effect by oscilaltion.
Further, described expansion link 4 is provided with compression end 11 with the position of absorption surface, and compression end 11 directly contacts workpiece, has
Good resistance to compression and wear-resistant effect, described compression end 11 is the semicircular structure that cambered surface is outside, and the structural advantage of semicircular structure the most more can
Protection surface of the work is the most frayed, and half circular diameter of described compression end 11 is more than the diameter of through hole, described expansion link 4 and bullet in via layer 3
One end diameter dimension of spring body 6 contact is identical with the tubular structure internal diameter on spring seat 5, it is to avoid expansion link 4 skids off via layer 3, described
One end diameter dimension that expansion link 4 contacts with spring body 6 is identical with the tubular structure internal diameter on spring seat 5, prevents expansion link 4 upper
Downward moving rocks.
Further, described spring seat 5 can bear gross weight is clamping workpiece weight 1.5 times, to 2 times, prevents lifting pressing
Mechanism increases the weight of the holding capacity of spring seat 5 when applying pressure, prevents the situation of overload from occurring, and the holding capacity of generally more than 2 times also can affect bullet
The counteracting force of spring pedestal 5 entirety, the most excessive counteracting force can defective work piece surface.
The above, only the application preferably detailed description of the invention, but the protection domain of the application is not limited thereto, any it is familiar with this skill
The technical staff in art field in the technical scope that the application discloses, the change that can readily occur in or replacement, all should contain the protection model in the application
Within enclosing.Therefore, the protection domain of the application should be as the criterion with scope of the claims.
