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.

The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, the present invention is further detailed explanation by reference to the accompanying drawings.
The schematic diagram of accompanying drawing for simplifying, basic structure of the present invention is only described in a schematic way, so it only shows the formation relevant with the present invention.
As shown in Figure 1, 2, a kind of adjustable vacuum clamp for thin-wall box body mainly comprises casing 1, pedestal 2, vacuumizes bar 3, ventilation mouth plug 4, sealing lip 5, regulates 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 laminatings regulate the front end face of support bar 6, sealing lip 5 to keep laminating with the respective side of casing 1.
As shown in Figure 3, regulate in support bar 6 front end face and have end face air channel 10, there is longitudinal passage 11 at center, there is the support bar ring-shaped ventilation groove district 13 that diameter is slightly little at rear portion, there is the middle part of horizontal communication hole 12 in support bar ring-shaped ventilation groove district 13 side, support bar sealing ring 9 is fixed on two ends in support bar ring-shaped ventilation groove district 13, and they form a relatively independent gas passage.The support bar screw thread 14 that regulates support bar 6 afterbodys to have adjusting position to use.Sealing lip 5 is fixed on and regulates support bar 6 heads to seal.
As shown in Figure 4, vacuumize bar 3 afterbodys and vacuumize bar screw thread 15, vacuumize bar air flue 17 on axis, front end vacuumizes bar dual-seal circle 16, ventilation mouth plug 4 with vacuumize bar air flue 17 and coordinate and seal.
As Fig. 5, shown in Fig. 6, on pedestal 2, there are some support bar datum holes 18, base vacuum chamber 8 and pedestal air flue 22.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.Regulate support bar 6 and support bar datum hole 18 to be slidably matched, vacuumize bar 3 and be slidably matched with the indoor chamber 20 of base vacuum.
As shown in Figure 2 when SBR, the respective side of limited block 7 sides and casing 1 is parallel and keep certain distance, and pedestal 2 has certain distance with limited block 7 and casing 1.Vacuumize the bottom surface laminating in bar 3 front end faces and the indoor chamber 20 of base vacuum in reset mode.During duty as shown in Figure 1, mobile foundation 2 makes front end face and limited block 7 laminatings of pedestal 2, then pedestal 2 is fixed on workbench, the support bar screw thread 14 that rotates respectively zones of different produces and moves axially, make to regulate the front end face of support bar 6, sealing lip 5 keeps laminating with the respective side (step that comprises differing heights) of casing 1, casing 1 side now, end face air channel 10, longitudinal 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, vacuumize bar air flue 17, vacuumize bar dual-seal circle 16 and ventilation mouth plug 4 formation one confined spaces, then rotation vacuumizes bar screw thread 15 and makes it to the direction motion of leaving base vacuum chamber 8, at this moment confined space volume becomes the large negative pressure that forms, the volume of vacuum and confined space initial residual gas is inversely proportional to, with vacuumize bar 3 displacements and be directly proportional.Now casing 1 side under pull of vacuum with the front end face close contact that regulates support bar 6, complete clamping process.
When casing 1 completion of processing need to be dismantled, first rotation vacuumizes the bottom surface that bar screw thread 15 makes to vacuumize bar 3 front end faces and the indoor chamber 20 of base vacuum and fits in reset mode, thereby 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 is connected, can easily remove pedestal 2, during refitting casing 1, only need mobile foundation 1 to make front end face and limited block 7 laminatings of pedestal 2, then pedestal 2 is fixed on workbench, the bottom surface laminating that vacuumizes bar 3 front end faces and the indoor chamber 20 of base vacuum resets, by ventilation mouth plug 4 with vacuumize bar air flue 17 and coordinate and can complete preparation, regulate the position of support bar 6 in original installation process, to adjust and no longer need to readjust.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
