Abstract
The invention relates to a cutting clamp for a universal joint retainer window. The cutting clamp comprises a fixed clamp and a movable clamp, wherein the fixed clamp is formed by connecting two concentric round plates through a screw, the circle center of one round plate is fixedly arranged on a rotating shaft of a servo motor, a screw hole is formed in the circle center of the other round plate, a through hole is formed in the circle center of the movable clamp, and a bolt penetrates through the through hole of the movable clamp and is matched with the screw hole of the fixed clamp through a screw thread; an adjustable radial compaction device for radially clamping and positioning a retainer is arranged between the two round plates of the fixed clamp, and the retainer rotates at a set angle by the servo motor, so that cutting of the circumferential retainer window is implemented. The cutting clamp is suitable for clamps of retainers of all kinds of specifications, and has the advantages of simplicity and convenience in clamping, no clamp abrasion, avoidance of maintenance, high processing efficiency, low processing cost, good window processing precision and the like.
Description
Technical field
The present invention relates to the machining tool fixture of auto parts and components, specifically cut with regard to universal joint retainer window
Frock.
Background technology
Retainer is rzeppa joint vitals, and universal joint retainer is made up of inside and outside spherical surface and two planes,
The sphere even circumferential of two plane middles is formed with six windows.At present, the processing of universal joint retainer window, usually adopts
With traditional artificial Presser Dashing hole forming, each hole is required for through punching press twice, once grinding process, is to rush window for the first time
Forming hole, is to rush window size hole for the second time, then carries out grinding.Its major defect is: the retainer of different size needs not
Same mould, number of molds is huge, and mould uses process presence abrasion, produces dimensional discrepancy, and needs often adjust, safeguard, plus
Work high cost, generation efficiency are low, affect machining accuracy；The window punching press joint-cutting depth of parallelism is poor, and joint-cutting is poor with surface perpendicularity, otch
Poor dimensional precision, processing technique is complicated.
Content of the invention
The purpose of the present invention is that there is shortcoming for prior art, provides that a kind of clamping is simple and convenient, fixture no weares and teares, exempts from
Safeguard, high in machining efficiency, processing cost is low, window good processing accuracy, for the universal joint retainer window of laser cutting parameter
Mouth cutting clamper.
Technical scheme includes stationary fixture and floating holder, and mainly stationary fixture is by two pieces of concentric circles
Flat board is connected by screw composition, and the center of circle of one of circle flat board is fixedly mounted in servomotor rotating shaft, another piece of circle
The center of circle of shape flat board is formed with screw, and the center of circle of floating holder is formed with through hole, and bolt passes through through hole and the stationary fixture of floating holder
Screw screw thread cooperation；It is provided with scalable radial compaction device, described scalable between two pieces of circular flat boards of stationary fixture
Radial compaction device adopts compact heap and electromagnetic mechanism composition, and compact heap is had two, is arranged on stationary fixture and contacted with retainer
Circular flat board in made radial groove, two compact heaps are equal with a distance from the circular flat board center of circle；Electromagnetic mechanism is by electricity
Magnetic coil and bar magnet composition, bar magnet is arranged on solenoid inner chamber, and two compact heap back side is each and one of electromagnetic mechanism
One end of middle bar magnet is fixedly connected.
In above technical scheme, compact heap work surface has arc structure.
It is an advantage of the invention that using two pieces of circular flat board composition retainer jig for laser cutting, retainer is installed in solid
Between clamp tool and two plate level of floating holder, radially positioning is compressed by compact heap, servomotor revolves according to set angle
Turn retainer, the cutting of retainer window is realized by laser cutting machine, by adjusting the radial position of compact heap, go for each
Plant the fixture of specification retainer, its clamping is simple and convenient, fixture no weares and teares, non-maintaining, high in machining efficiency, processing cost is low, window
Mouth good processing accuracy.
Brief description
Fig. 1 is the structural representation of the present invention.
1 stationary fixture, 2 floating holders, 3 bolts, 4 retainers, 5 compact heaps, 6 electromagnetic mechanisms, 7 radial grooves.
Specific embodiment
Universal joint retainer window cutting clamper as shown in Figure 1, including stationary fixture 1 and floating holder 2, stationary fixture
1 is connected by screw by two pieces of concentric circular flat boards and forms, and the center of circle of one of circle flat board is fixedly mounted on servo electricity
In machine rotating shaft, the center of circle of another piece of circular flat board is formed with screw, and the center of circle of floating holder 2 is formed with through hole, and bolt 3 passes through activity folder
The through hole of tool 2 is connected with the screw screw thread of stationary fixture 1；It is provided with adjustable between two pieces of circular flat boards of stationary fixture 1
Section radial compaction device, described scalable radial compaction device is formed using compact heap 5 and electromagnetic mechanism 6, and compact heap 5 has two
Individual, it is arranged in made radial groove 7 on the circular flat board that stationary fixture 1 is contacted with retainer 4, two compact heaps 5 are from circle
The distance in the shape flat board center of circle is equal, and the work surface of compact heap 5 is located at the flat of the circular flat board of stationary fixture 1 and retainer 4 contact side
In face, the work surface of described compact heap 5 is the contact surface between compact heap 5 and retainer 4, and compact heap 5 can radially chute 7
Slide, install in the axial restraint of the circular flat board of stationary fixture 1；Electromagnetic mechanism 6 has two, is made up of solenoid and bar magnet,
Bar magnet is arranged on solenoid inner chamber, and two compact heap 5 back sides are each fixed with one end of bar magnet in one of electromagnetic mechanism 6
Connect.When the solenoid is activated, bar magnet promotes compact heap 5 to clamp retainer 4, realizes laser instrument to retainer 4 window
Cutting, after having cut a window, servomotor carries out the next one according to setting one angle of rotation, laser instrument to retainer 4
The cutting of window.
Compact heap 5 work surface has arc structure, and compact heap 5 work surface adopts nonmetallic materials.
Gripping block 5 can be using from cylindrical inward-facing clamping to retainer 4, it would however also be possible to employ outwards strut pressure from inner circle
Tightly.Solenoid controlled power supply is provided by controlling organization.Compact heap 5 can adopt two or more, and its quantity can be according to retainer 4
Diameter determine.
