Abstract
The invention relates to a hydraulic clamp compatible for machining of steering knuckles of multiple varieties. The hydraulic clamp comprises a positioning plate, a hydraulic oil cylinder and a lateral positioning clamping oil cylinder, wherein the positioning plate is fixed to a machine tool C-shaft rotating disc through a first connecting screw, and a hydraulic oil way is arranged in the positioning plate; the hydraulic oil cylinder and the lateral positioning clamping oil cylinder are fixed to the positioning plate through a second connecting screw, the hydraulic oil cylinder is located in the center of the positioning plate, and the lateral positioning clamping oil cylinder is located on the outer edge of the positioning plate; a hydraulic push rod is arranged in the center of the hydraulic oil cylinder, a main positioning block is fixed to the center of the hydraulic oil cylinder through a third connecting screw, a clamping rod is connected with the hydraulic push rod in a threaded mode, and a clamping block is located on the clamping rod. The hydraulic clamp has the beneficial effects that the three replaceable components, namely the main positioning block, the clamping rod and the lateral positioning clamping oil cylinder, only occupy 20%-30% of the storage space compared with the mode that the part, located on the whole positioning plate, of the clamp and the positioning plate are replaced, and product switching time can be shortened.
Description
Technical field
The invention belongs to clamp for machining technical field, particularly relate to the hydraulically operated fixture of a kind of compatible multi items knuckle processing.
Background technology
Spindle is one of automobile main parts size, and spindle processing is mainly completed by the process equipment such as milling machine, lathe.
In the knuckle course of processing, needing the clamping of fast and stable, spindle needs higher machining accuracy simultaneously.Current adds
Work, clamping process disclosure satisfy that certain processing request substantially, but are as the fast development of automobile making, and spindle becomes
Manufacture in individual character small batch.Manufacture special clamping tooling for processing if each product, frock clamp will certainly be caused
The wasting of resources and take storage space.
, there is following defect: 1, the knuckle of each model need to be prepared special in the existing fixture being used for processing spindle
Clamp for machining；2, to take storage space bigger for idle clamp for machining；3, production switch is cumbersome, needs a whole set of fixture to cut
Changing, the production switch cycle is long, and switching need to search processing round dot again every time.
Summary of the invention
It is an object of the invention to the deficiency overcoming prior art to exist, and provide that a kind of switching cycle is short, the debugging time is short can
The hydraulically operated fixture of compatible multi items knuckle processing.
It is an object of the invention to complete by following technical solution, including location dish, hydraulic jack, side locating clip locking oil cylinder,
Described location dish is fixed on lathe C axle rotating disk by the first attachment screw, has the oil circuit of logical hydraulic pressure inside the dish of location；Hydraulic pressure
Oil cylinder, side locating clip locking oil cylinder are fixed on the dish of location by the second attachment screw, and hydraulic jack is positioned at the center of location dish, side
Locating clip locking oil cylinder is positioned at the exterior rim of location dish；Hydraulic push rod is placed in the center of hydraulic jack, and main locating piece is by the 3rd connection
Screw is fixed in hydraulic jack in the heart, and clamping bar is threaded connection mode and is connected with hydraulic push rod, and clamping block is positioned at clamping
On bar.
As preferably, the d1 on described main locating piece coordinates face to coordinate in matched in clearance between face with the d2 on hydraulic jack, its
The spacing distance in gap is 0.01MM.
As preferably, the D1 on described main locating piece coordinates the radial dimension in face to coordinate the radial direction in face less than the D2 on knuckle
Size.
Main locating piece, the clamping bar of the invention have the benefit that 1, changing, that side locating clip locking oil cylinder three parts only account for replacing is whole
The 20%～30% of the storage space of individual location dish (containing) above fixture；2, manufacture cumbersome because of location dish oil circuit, the most compatible
One model, can become manufacturing cost and the time of half minimizing fixture；3, the switching time of product can be reduced.
Accompanying drawing explanation
Fig. 1 is the hydraulically operated fixture structural representation of the present invention.
Fig. 2 is the knuckle mounting structure schematic diagram of the present invention.
Fig. 3 is main locating piece and the hydraulic jack matched in clearance structural representation of the present invention.
Fig. 4 is hydraulic push rod and the clamping bar thread matching structure schematic diagram of the present invention.
Label in accompanying drawing is respectively as follows: 1, lathe C axle rotating disk；2, the first attachment screw；3, location dish；4、
Second attachment screw；5, hydraulic jack；6, main locating piece；7, hydraulic push rod；8, clamping block；9, clamping
Bar；10, side locating clip locking oil cylinder；11, the 3rd attachment screw；12, knuckle.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention done detailed introduction: as shown in accompanying drawing 1 to 4, the present invention includes location dish 3, liquid
Compressing cylinder 5, side locating clip locking oil cylinder 10, described location dish 3 is fixed on lathe C axle rotating disk 1 by the first attachment screw 2
On, the internal oil circuit having logical hydraulic pressure of location dish 3；Hydraulic jack 5, side locating clip locking oil cylinder 10 are solid by the second attachment screw 4
Being scheduled on location dish 3, hydraulic jack 5 is positioned at the center of location dish 3, and side locating clip locking oil cylinder 10 is positioned at the outer rim of location dish 3
Limit；Hydraulic push rod 7 is placed in the center of hydraulic jack 5, and main locating piece 6 is fixed on hydraulic jack 5 by the 3rd attachment screw 11
In in the heart, clamping bar 9 is threaded connection mode and is connected with hydraulic push rod 7, clamping block 8 be positioned on clamping bar 9, clamping
Block 8 is used for clamping knuckle 12 and is processed.
D1 on described main locating piece 6 coordinates face to coordinate in matched in clearance between face with the d2 on hydraulic jack 5, its gap
Spacing distance is 0.01MM.
D1 on described main locating piece 6 coordinates the radial dimension in face to coordinate the radial dimension in face less than the D2 on knuckle 12.
The present configuration compatible multi items mach switching of knuckle, can be according to D2, H size weight of different model knuckle
New production more change owner locating piece 6, clamping bar 9, and side locating clip locking oil cylinder 10, the switching of part knuckle pertains only to therein
Two or the replacing of single parts；During switching Product processing, because of the replacing without reference to location dish 3, pertain only to several widget,
And the gap of the matched in clearance of main locating piece 6 and hydraulic cylinder 5 typically only 0.01, for the public affairs of knuckle processing ± 0.10
Difference, this gap is negligible, therefore without again searching machining round dot (X-axis, Y direction), only need to be to Z axis according to different shaped
Number knuckle H size is adjusted.
The present invention is not limited to above-mentioned embodiment, no matter making any change on its shape or material are constituted, every employing this
Bright provided structure design, is all a kind of deformation of the present invention, is all considered as within scope.
