Description

Many boring positioning and clamping mechanisms

Technical field

The present invention relates to the tool structure that many clamping boring of same model specification part location clamps, specifically a kind of many boring positioning and clamping mechanisms belong to mechanical processing technique equipment technology field.

Background technology

In the swivel joint manufacture process, the disk like part end face porous processing all uses conventional metal cutting to process to finish.Finish at drilling machine such as scribing by bench worker boring or use drill jig.Advanced is exactly that the work in-process heart is by finishing the processing of porous on the chuck three-jaw clamping at present.There are the problems such as working strength is large, scale error large, inefficiency in the boring of manual operations line drilling machine.The machining center clamping, though can guarantee higher dimensional accuracy, reduction working strength, the problems such as utilization rate of equipment and installations is low, equipment cost is high are arranged.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art, a kind of many boring positioning and clamping mechanisms are provided, its simultaneously the needs of many same model specifications of clamping carry out the disk-like accessory of end face porous drilling, by disposable quick-clamping processing to a plurality of parts, guarantee the machining accuracy of size, greatly reduced workman's working strength, improved utilization rate of equipment and installations, reduce production cost and had fabulous interchangeability, had the larger range of work.

According to technical scheme provided by the invention: many boring positioning and clamping mechanisms is characterized in that: comprise the first positioning key, clamp body, platen, T-shaped bolt, backing plate, the second positioning key, the 3rd positioning key, screw, handle, hold-down bolt, supporter, bolt, push pedal, straight pin, pressing plate, screw and fixing V-block; Clamp body cooperates with T-shaped groove in the platen by the second positioning key and uses T-shaped bolt-locking; Backing plate cooperates with locating slot on the clamp body by the 3rd positioning key and uses screw lock; Fixedly V-block cooperates with locating slot on the clamp body by the first positioning key and uses screw lock, and fixedly a plurality of V-shaped grooves on the V-block are interior for placing to be processed; A plurality of supporters are arranged side by side and are corresponding one by one with a plurality of V-shaped grooves on the fixing V-block, supporter respectively by bolt-locking on backing plate, be separately installed with a slidably push pedal in each supporter, the push pedal front end is by the straight pin pressing plate that is hinged, hold-down bolt is installed in the supporter, the hold-down bolt front end connects push pedal, the hold-down bolt rear end is installed with for the handle that drives its rotation, turning handle can drive hold-down bolt order about push pedal in supporter to front slide, to be processed is pressed on fixedly in the V-block fully.

As a further improvement on the present invention, on the described clamp body on the corresponding fixedly V-block position of V-shaped groove the workpiece backing plate is installed.

Compared with the prior art the present invention has the following advantages:

(1) the present invention is simple and practical, and flexible operation also has good interchangeability.

(2) after the invention process, improved working (machining) efficiency, guaranteed machining accuracy, increased dimensional stability, greatly reduced working strength, increased substantially utilization rate of equipment and installations.

(3) pass through to adjust different fixedly V-blocks after the invention process, change the fixedly position of V-block, adopt corresponding backing plate and pressing plate, can process the part of the specification of the same race in the certain numerical value scope, promoted greatly working ability, it is pioneering that the processing technology of this structure still belongs in the swivel joint manufacturing.

The specific embodiment

The invention will be further described below in conjunction with concrete drawings and Examples.

As shown in the figure: among the embodiment many boring positioning and clamping mechanisms mainly by the first positioning key 1, clamp body 2, platen 3, T-shaped bolt 4, backing plate 5, the second positioning key 6, the 3rd positioning key 7, screw 8, handle 9, hold-down bolt 10, supporter 11, bolt 12, push pedal 13, straight pin 14, pressing plate 15, to be processed 16, location-plate 17, screw 18 and fixedly the parts such as V-block 19 form.

Such as Fig. 1 ~ shown in Figure 4, clamp body 2 cooperates with T-shaped groove in the platen 3 by the second positioning key 6 and locks with T-shaped bolt 4; Backing plate 5 cooperates with locating slot on the clamp body 2 by the 3rd positioning key 7 and locks with screw 8; Fixedly V-block 19 cooperates with locating slot on the clamp body 2 by the first positioning key 1 and locks with screw 18, and fixedly a plurality of V-shaped grooves on the V-block 19 are interior for placing to be processed 16; A plurality of supporters 11 are arranged side by side and are corresponding one by one with a plurality of V-shaped grooves on the fixing V-block 19, supporter 11 is locked on the backing plate 5 by bolt 12 respectively, be separately installed with a slidably push pedal 13 in each supporter 11, push pedal 13 front ends are by straight pin 14 hinge pressing plates 15, hold-down bolt 10 is installed in the supporter 11, hold-down bolt 10 front ends connect push pedal 13, hold-down bolt 10 rear ends are installed with for the handle 9 that drives its rotation, turning handle 9 can drive hold-down bolt 10 order about push pedal 13 in supporter 11 to front slide, to be processed 16 is pressed on fixedly in the V-block 19 fully.

As shown in Figure 1, on the described clamp body 2 on the corresponding fixedly V-block 19 position of V-shaped groove workpiece backing plate 17 is installed, can prevent like this clamp body 2 that when clamped, weares and teares for to be processed 16, thereby prolong service life of the present invention.

Concrete applicable cases of the present invention is as follows:

At first two the second positioning keys 6 are fastened on the clamp body 2, clamp body 2 cooperates with T-shaped groove in the platen 3 by the second positioning key 6, determine the position of clamp body 2 on platen 3 with this, then with two T-shaped bolts 4 clamp body 2 and platen 3 are locked mutually.Two the 3rd positioning keys 7 are fastened on the backing plate 5, and backing plate 5 cooperates with locating slot on the clamp body 2 by the 3rd positioning key 7, determines the position of backing plate 5 on clamp body 2 with this, then with several screws 8 backing plate 5 and clamp body 2 is locked mutually.Fixedly V-block 19 cooperates with locating slot on the clamp body 2 by the first positioning key 1, with this definite fixedly position of V-block on clamp body 2, then with five screws 18 fixedly V-block 19 lock mutually with clamp body 2.

Add man-hour, to be processed 16 is positioned on the workpiece backing plate 17, turning handle 9 drive hold-down bolts 10 order about push pedal 13 in supporter 11 to front slide, by flexibly rotation of straight pin 14, self-centering and reinforcing, each pressing plate 15 can be simultaneously automatically with in two to be processed 16 V-shaped groove that is pressed on fully on the fixing V-block 19, so just form to be processed 16 and added the necessary condition that need confirm that Working position, location clamping can be processed man-hour, thus the purpose of design that has reached quick-clamping, shortened the process-cycle, reduces working strength, enhances productivity.
