Abstract
The invention relates to the machining technical field of fixing fixtures for machining 'T'-shaped or 'L'-shaped section bars, and discloses a variable-specification fixture for fixing a 'T'-shaped or 'L'-shaped section bar. When the 'T'-shaped or 'L'-shaped is clamped and fixed, different gestures corresponding to tooth-shaped cushion plates can be changed by means of adjusting adjustable bolts at different positions, the fixing fixture which has different sectional shapes and is used for machining the 'T'-shaped or 'L'-shaped section bar can be quickly adjusted, and fixing requirements for machining various 'T'-shaped or 'L'-shaped section bars with different thicknesses and changeable thicknesses are met. The changeable fixture replaces various special fixtures, storage occupied spaces and management workload for the fixtures are reduced, manufacturing period of a product is shortened, production efficiency is improved, and production cost is lowered.
Description
Technical field
The present invention relates to the technical field of " T " shape in the machining or " L " shape section bar processing with stationary fixture.
Background technology
In airplane parts processing, " T " shape commonly used or " L " shape section bar further are processed into the part of designing requirement.For this reason, need in the process " T " shape or " L " shape section bar are fixed.For the above-mentioned section bar of different cross section size, method commonly used is the special fixture with specific dimensions as shown in Figure 1.Because above-mentioned section bar cross section specification related in the actual production is different, pairing special fixture specification is many when causing processing, preserves to take up room greatly, both has been not easy to management, reduces production efficiency again.Change in the production practices anchor clamps time spent be about 1 hour/inferior.The manufacturing process of special fixture is complicated simultaneously, the cycle is long, cost is high.
Summary of the invention
The objective of the invention is: for the specification that solves special fixture many; The problem that preservation takes up room greatly, is not easy to manage; A kind of " T " shape or the fixing anchor clamps of using of " L " shape section bar of variable format are proposed; Realize that a kind of variable anchor clamps replace multiple special fixture, enhance productivity the purpose that reduces production costs.
Technical scheme of the present invention is: in order to solve the problems of the technologies described above, what the present invention proposed a kind of shape-variable and size fixedly uses anchor clamps.As shown in Figure 2; At original stationary fixture: comprise on the basis of clamp body 1, clamp body 2 and clamp body 3; On clamp body 1, uniformly-spaced vertically have four two ends through holes all with the level; The stepped hole in the outside is an internal thread hole; Built-in respectively externally threaded governor motion moving up and down 4, governor motion 5, governor motion 7, the governor motion 8 of having, governor motion 4 and governor motion 5 are connected with profile of tooth backing plate 6 hinges movably, and governor motion 7 and governor motion 8 are connected with profile of tooth backing plate 9 hinges movably; Four through hole inboards are waist shape stepped hole, when preventing that rocker bar bearing from rotating and clamp body interfere; Clamp body 2 uniformly-spaced laterally has two two ends through holes all with the level up and down; The stepped hole in the through hole outside is an internal thread hole; Built-in respectively externally threaded governor motion 10 and 11 of having; Governor motion 10 is connected with profile of tooth backing plate 12 movably through hinge with 11, and the through hole inboard is a waist shape stepped hole, when preventing that rocker bar bearing from rotating and clamp body interfere; Clamp body 3 uniformly-spaced laterally has two two ends through holes all with the level up and down; The stepped hole in the through hole outside is an internal thread hole; Built-in externally threaded governor motion 14 and 15 of having; Governor motion 14 is connected with profile of tooth backing plate 13 movably through hinge with 15, and the through hole inboard is a waist shape stepped hole, when preventing that rocker bar bearing from rotating and clamp body interfere.Profile of tooth backing plate 6,9,12, form a T-shape, " L " shape or the not T-shape, the cavity of " L " shape of uniform thickness between 13.
The present invention has the following advantages: compared with prior art; Adopt the present invention, add man-hour, only need make the fixing anchor clamps of using of a cover at " T " shape and " L " shape section bar; Adjusting bolt through the adjustment different parts; Just can change the different attitude of corresponding profile of tooth backing plate, rapid adjustment goes out " T " shape or the processing of " L " shape section bar of different cross section shape and uses stationary fixture, satisfies " T " shape of various different-thickness, thickening degree or the fixed demand of " L " shape section bar processing; Realized that a kind of variable anchor clamps replace multiple special fixture, the preservation that has reduced anchor clamps takes up room and management workload, has shortened the product manufacturing cycle, has improved production efficiency, has reduced production cost.

The specific embodiment
Below in conjunction with accompanying drawing the assembling and fixing being used as with making of anchor clamps of variable format of governor motion among the present invention are described in detail:
The present invention has obtained application being processed in the airplane parts by " T " shape or " L " shape section bar of Shanxi Aircraft Industry (Group) Corp., Ltd..The assembling of governor motion such as Fig. 3 or shown in Figure 4 at first, connect as one connector 16 and connecting rod 18 with straight pin 17; Then, the above widget that connects is connected with screwed hole on profile of tooth backing plate 6, profile of tooth backing plate 9, profile of tooth backing plate 12, the profile of tooth backing plate 13 through connector 16 respectively; At last; The above assembly that connects is respectively charged in the waist shape stepped hole on clamp body 1, clamp body 2 and the clamp body 3; To regulate bolt 19 screws in respectively in clamp body 1, clamp body 2 and the clamp body 3 respective threads stepped holes; Regulate the groove position that boss female thread portion that bolt 19 1 ends have groove enters into connecting rod 18 fully until being screwed into, so just accomplished the assembling of anchor clamps.
When the fixing section bar of need is " T " shape or " L " shape; As shown in Figure 2; At first adjust the adjusting bolt 19 in governor motion 4,5,7,8,10,11,14 and 15; After making profile of tooth backing plate 6,9,12, forming the enough big cavity of a corresponding T-shape or " L " shape between 13, put into section bar to be fixed, 19 pairs of section bars enforcements of the adjusting bolt in screw successively then governor motion 4,5,7,8,10,11,14 and 15 add and fasten.
When the fixing section bar of need is oblique " T " shape or oblique " L " shape; As shown in Figure 5; At first adjust the adjusting bolt 19 in governor motion 4,5,7,8,10,11,14 and 15; Make profile of tooth backing plate 6,9,12, form a corresponding tiltedly T-shape between 13 or tiltedly behind " L " shape cavity, put into section bar to be fixed, 19 pairs of section bars of the adjusting bolt in screw successively then governor motion 4,5,7,8,10,11,14 and 15 are implemented to add to fasten.
When the fixing section bar of need is thickening degree " T " shape or " L " shape; As shown in Figure 6; At first adjust the adjusting bolt 19 in governor motion 4,5,7,8,10,11,14 and 15; After making profile of tooth backing plate 6,9,12, forming a corresponding thickening degree T-shape or " L " shape cavity between 13, put into section bar to be fixed, 19 pairs of section bars of the adjusting bolt in screw successively then governor motion 4,5,7,8,10,11,14 and 15 are implemented to add to fasten.
