Abstract
The invention relates to an adjustable vacuum clamp for a thin-wall box body, which comprises a box body, a base, evacuation pole, an evacuation pole double seal ring, a ventilation port end cap, a seal lip, an adjustment supporting rod, a supporting rod seal ring and a stop block. The front side face of the stop block is parallel to corresponding side face of the box body, and a certain distance is maintained between the front side face of the stop block and the corresponding side face of the box body. During the working of the thin-wall box body, the front end face of the base and the stop block are fitted and fixed on a table, the position of the adjustment supporting rod is moved to enable the front end faces of the seal lip and the adjustment supporting rod and the side face of the thin-wall box body (including steps of different heights) to be fitted to form a closed space, the evacuation pole is moved in the direction of the departure from the base to form a negative pressure, and the vacuum degree of the closed space is inversely proportional to the volume of initial residual gas in the closed space and directly proportional to the movement distance of the evacuation pole. The adjustable vacuum clamp can displace a vacuum chuck and process raised vertical side faces of box bodies, requires no special vacuum chuck gas supply device, and is simple in structure and low in price.
Description
Technical field
The present invention relates to a kind of adjustable thin-wall box body vacuum fixture, can replace the vacuum cup machining box that the vertical side of bossing is arranged, do not need special vacuum cup feeder.
Background technology
Along with the further raising of properties of product, originally a large amount of thin-wall box body parts that use have extensively appeared at civilian industry article field in the Aeronautics and Astronautics field.The thin-wall box body part meets the development trend of product " light, thin, little ", avoided the latent defects such as pore, crackle of cast member, weldment to greatest extent.But thin-walled parts rigidity is low, and clamping is difficulty very, under factor affecting such as cutting force, heat in metal cutting, cutting chatter, machining deformation takes place very easily, wayward machining accuracy and raising working (machining) efficiency.Machining deformation and working (machining) efficiency become the bottleneck problem of thin-wall box body part processing.
The conventional vacuum sucker structure is complicated, and the machining box vertical side is inconvenient, with the contact-making surface of part can only be the plane, on the plane bossing can not be arranged, need special feeder, use flexibility relatively poor, cost an arm and a leg.
Summary of the invention
The technical problem that the present invention will solve is that to overcome existing vacuum cup volume big, and inconvenience is used in the processing parts side, with the contact-making surface of part can only be the plane, on the plane bossing can not be arranged, need special feeder, use the relatively poor shortcoming of flexibility.

The specific embodiment
In order to make the object of the invention, technical scheme and advantage clearer, the present invention is done further detailed explanation in conjunction with accompanying drawing.The sketch map of accompanying drawing for simplifying basic structure of the present invention only is described in a schematic way, so it only shows the formation relevant with the present invention.
Like Fig. 1, shown in 2, a kind of adjustable thin-wall box body vacuum fixture mainly comprises casing 1, pedestal 2, vacuumizes bar 3, ventilation mouth plug 4, sealing lip 5, adjustable support bar 6, limited block 7, support bar sealing ring 9 and vacuumize bar dual-seal circle 16.Limited block 7 sides are parallel with casing 1 respective side, and pedestal 2 front end faces and limited block 7 are fitted, and the front end face of adjustable support bar 6, sealing lip 5 keep fitting with the respective side of casing 1.
As shown in Figure 3; On adjustable support bar 6 front end face end face air channel 10 is arranged; There is vertical passage 11 at the center, and there is the slightly little support bar ring-shaped ventilation groove district 13 of diameter at the rear portion, and the side has horizontal communication hole 12 to be in the middle part in support bar ring-shaped ventilation groove district 13; Support bar sealing ring 9 is fixed on two ends in support bar ring-shaped ventilation groove district 13, and they constitute a relatively independent gas passage.The support bar screw thread 14 that adjustable support bar 6 afterbodys have adjusting position to use.Sealing lip 5 is fixed on adjustable support bar 6 heads and seals.
As shown in Figure 4, vacuumize bar 3 afterbodys and vacuumize bar screw thread 15, vacuumize bar air flue 17 on the axis, front end vacuumizes bar dual-seal circle 16, ventilation mouth plug 4 with vacuumize bar air flue 17 and cooperate and seal.
Like Fig. 5, shown in Figure 6, some support bar datum holes 18 are arranged, base vacuum chamber 8 and pedestal air flue 22 on the pedestal 2.The afterbody of support bar datum hole 18 has support bar datum hole screw thread 21 to match with support bar screw thread 14; Base vacuum chamber 8 afterbodys have base vacuum chamber screw thread 19 and vacuumize bar screw thread 15 and match.Adjustable support bar 6 is slidingly matched with support bar datum hole 18, vacuumizes bar 3 and is slidingly matched with the indoor chamber 20 of base vacuum.
As shown in Figure 2 when being in SBR, limited block 7 sides are parallel with the respective side of casing 1 and keep certain distance, and pedestal 2 has certain distance with limited block 7 and casing 1.The bottom surface applying that vacuumizes bar 3 front end faces and the indoor chamber 20 of base vacuum is in reset mode.As shown in Figure 1 during duty, mobile foundation 2 makes the front end face of pedestal 2 and limited block 7 fit, and then pedestal 2 is fixed on the workbench; The support bar screw thread 14 that rotates zones of different respectively produces and moves axially, and makes the front end face of adjustable support bar 6, sealing lip 5 keep applying to get final product with the respective side (step that comprises differing heights) of casing 1, at this moment casing 1 side; End face air channel 10, vertical passage 11, horizontal communication hole 12; Support bar ring-shaped ventilation groove district 13, support bar sealing ring 9, pedestal air flue 22; Base vacuum chamber 8 vacuumizes bar air flue 17, vacuumizes bar dual-seal circle 16 and forms a confined space with ventilation mouth plug 4; Rotation vacuumizes bar screw thread 15 and makes it to the direction motion of leaving base vacuum chamber 8 then; At this moment the confined space volume becomes the big negative pressure that forms, and the volume of vacuum and confined space initial residual gas is inversely proportional to and vacuumizes bar 3 displacements and is directly proportional.This moment, casing 1 side closely contacted with the front end face of adjustable support bar 6 under pull of vacuum, accomplished clamping process.
When casing 1 completion of processing need be dismantled; At first rotation vacuumizes bar screw thread 15 and makes the bottom surfaces applyings that vacuumize bar 3 front end faces and the indoor chamber 20 of base vacuum be in reset mode; Thereby the confined space volume diminishes and removes negative pressure, for convenient disassembly can also be removed ventilation mouth plug 4, then with gas injection device with vacuumize bar air flue 17 injecting compressed air that links to each other; Can easily remove pedestal 2; Refitting only needs during casing 1 mobile foundation 1 to make the front end face of pedestal 2 and limited block 7 fit, and pedestal 2 is fixed on the workbench to get final product then, and the bottom surface applying that vacuumizes bar 3 front end faces and the indoor chamber 20 of base vacuum resets; With ventilation mouth plug 4 with vacuumize bar air flue 17 and cooperate and can accomplish preparation, the position of adjustable support bar 6 has been adjusted no longer in original installation process and need have been readjusted.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
