Wherein, in order to overcome in the problem of fixture of the prior art is excessive, the present embodiment, in view of the peace of different connecting rods
Dress mode and adjoining dimensions, therefore, devise a kind of public fixture-modular fixture available for group process.
Only carry out a small amount of adjustment or change some elements, modular fixture is just applicable to the installation of all connecting rods.This
Sample, as long as procedure arrangement production scheduling plan in groups can be pressed, it is possible to greatly reduce due to the machine required for connecting rod variety renovation
Bed adjustment time, reduces the Operational preparation time.
Specifically as shown in fig. 7, a kind of GT processing method of connecting rod, including：
According to the connecting rod to be processed, it is classified based on same or similar outward appearance, the unification of following process is used as
Positioning datum；
Connecting rod comprising identical machining element is arranged in same equipment and processed, and selects corresponding GT pair
It is processed, and further comprises：
Using the profile of the connecting rod to be processed as unified positioning datum, blank side is finished, size Control is existed
In the range of stock allowance, and based on side finish after blank, utilize with the side finish after blank shape phase
The processing Clamping Apparatus of Connecting Rod of matching is fixed.
Preferably, the base jig body of the processing Clamping Apparatus of Connecting Rod is provided with multiple fixing holes, based on different hairs
Base installs corresponding setting element or clamping element on corresponding fixing hole.
Preferably, the base jig of the Clamping Apparatus of Connecting Rod shares one.
Preferably, the GT processing method includes：Rule, rough mill both ends of the surface, finish-milling both ends of the surface, milling profile base

Wherein, the machining sketch chart of bowl cover bottom point, 13k ー 13m cut rear bar and cover part after 13n-13p is cut
Machining sketch chart, the 13a-13f that machining sketch chart, 13g-13i cut rear body section are the schematic flow sheets before connecting rod is cut, by
It is prior art in it, is not described in detail herein.
In one embodiment, illustrated for modular fixture, as shown in Figure 2,3, 4, be one embodiment in groups
Fixture, other are all similar therewith, herein without describing in detail.
Specifically, mechanism explanation：Base jig is the shared part of all connecting rod cap lower clamps of processing, refers to accompanying drawing
7, the effect of clamp body 1 is connecting machine tool workbench and workpiece to be machined, and clamp body is pressed on workbench by tommyhead bolt and nut
On, keeper and compressing member are installed above it.
Location-plate 2 is made of relatively hard materials, for bearing connecting rod lid, and upper plane is mainly positioned as connecting rod cap bottom
Face, limiting rod lid three degree of freedom, location-plate is fixed on clamp body by housing screw 5 and alignment pin 6.
The trailing flank of location-plate 2 is provided with pin 8 and screw 7, for installing locating piece, props up in various type connecting rod cap bottoms
Faying face on, the free degree of limiting rod lid bottom two.
Side locating piece is installed in the side of location-plate 2, propped up on the side of various type connecting rod cap bottoms, limiting rod
The one degree of freedom of lid bottom.The six-freedom degree of connecting rod cap bottom is limited completely, category positioning completely.Removable long nut 3
It can be moved with removable tommyhead bolt 10 in the groove of location-plate 2, different size connecting rod cap bottom can be met and clamp demand, it is mobile
The hypomere of long nut 3 is connected with removable tommyhead bolt, and mounting stud is used for compressing under connecting rod cap in the mobile epimere of long nut 3
Portion.
Operation principle：
I type and one kind of II type bowl cover bottom and another clamp structure figure are installed, it mainly aids in base jig.
See that accompanying drawing 8,9 and accompanying drawing 10,11,12 are mounted with miscellaneous small parts in base jig, and be mounted with I type and II type
Connecting rod cap bottom, the large and small difference in amphitypy connecting rod cap bottom is obvious as can be seen from Figure.Lay principle in connecting rod cap bottom：
Connecting rod cap lower end surface all should be able to be contacted all with the location-plate in base jig, it is ensured that be not likely to produce during compression
Deformation.Connecting rod cap lower shoulder face should be higher by location-plate, leave the space of withdrawing, be unlikely to be worked into location-plate and matrix.Even
Bowl cover lower side and faying face pass through screw and positioning by side locating piece 21 and post-positioning block 25 with base jig upper location-plate
Pin is connected, it is ensured that correct position is arranged in base jig at connecting rod cap bottom, is then compressed connecting rod cap with pressing system.Compress
Packing ring 23, screw are installed on system center platen 22（Do not marked in figure）, pressure head 28, clamp nut 26 and stud 27 will be even
Bowl cover bottom is pressed on clamp body.
That is, the present invention utilizes group technology principle, according to the similar feature of workpiece, identical machining element is arranged
Processed in same equipment, be designed to group process, GT is constituted by many group process.Because fixture can basis
Different product designs, therefore, the present invention is not described in detail herein.
Unified positioning datum：From connecting rod profile as benchmark, blank side is finished, by size Control in blank
In the margin of tolerance.
The effect of the present invention is described below：
（1）By procedure arrangement production scheduling plan in groups, it is possible to greatly reduce needed for frequently being changed due to connecting rod kind
The setting for machine time wanted, reduce the Operational preparation time.
（2）GT is standard technology, and process program is ripe, is quick for preparing new architecture connecting rod technique
, without big risk, the process debugging time is reduced, technologist's technological design time and substantial amounts of energy has been saved.
（3）For modular fixture, some positioning or clamping element are only designed and manufacture, when reducing designer's work
Between, save manufacturing cost and shorten the manufacturing cycle, finally make the cycle time of exploitation new product.
（4）Modular fixture is simple in construction, wide using scope.
（5）Save metal material and man-hour：The metal material of base jig and processing in manufacture modular fixture are saved
Man-hour, production cost reduction.
（6）Save parking space：The parking space of multiple sets of fixtures is originally needed, sleeve clamp storage is now only needed empty
Between, greatly save parking space.
Finally it should be noted that：The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention,
Although the present invention is described in detail with reference to the foregoing embodiments, for those skilled in the art, it still may be used
To be modified to the technical scheme described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic.
Within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., should be included in the present invention's
Within protection domain.
