Compared with the prior art, the utility model discloses at work, the action of pneumatic cylinder for lower movable plate moves towards last fly leaf, after the preliminary centre gripping of welding centre gripping union piece is treated with lower movable plate formation to last fly leaf, the air pump is aerifyd in to the elastic air cushion, elastic deformation takes place for the elastic air cushion, make elastic air cushion on the last fly leaf and the elastic air cushion on the lower movable plate form the firm centre gripping of treating a piece, effectively prevent two and treat to take place to move between the welding piece, can adapt to different appearances, the welding piece of treating of size, the centre gripping is reliable, welding efficiency has been improved.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure: 1. a base; 2. an upper movable plate; 3. a movable plate is lowered; 4. a hydraulic cylinder; 5. flashing; 6. a screw; 7. a nut; 8. an elastic air cushion; 9. and (4) bumps.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
As shown in fig. 1, the hydraulic welding platform comprises a base 1, an upper movable plate 2 and two lower movable plates 3, wherein a hydraulic cylinder 4 is arranged between the bottom of each lower movable plate 3 and the top of the base 1, the upper movable plate 2 is positioned above the two lower movable plates 3, flashes 5 are arranged on two sides of each upper movable plate 2, a pair of screw rods 6 respectively penetrating through the upper movable plates 2 are arranged on the base 1, a pair of nuts 7 are arranged on the screw rods 6, and the pair of nuts 7 are respectively positioned at the top and the bottom of each flash 5;
and the bottom of the upper movable plate 2 and the top of the lower movable plate 3 are both provided with an elastic air cushion 8 communicated with an air pump. The two pieces to be welded are respectively arranged on the two lower movable plates 3, then the lower movable plates 3 move towards the upper movable plate 2 through the action of the hydraulic cylinder 4, when the upper movable plate 2 and the lower movable plates 3 form primary clamping of a piece to be welded, clamped and connected, the air pump inflates the elastic air cushion 8, the elastic air cushion 8 is elastically deformed, so that the elastic air cushion 8 on the upper movable plate 2 and the elastic air cushion 8 on the lower movable plate 3 form firm clamping of the piece to be welded, the two pieces to be welded are effectively prevented from moving in series, the welding device can adapt to pieces to be welded with different shapes and sizes, the clamping is reliable, and the welding efficiency is improved; the adjustment of the position of the flash 5 is realized by adjusting the positions of the pair of nuts 7 on the screw 6, so that the quick adjustment of the initial position of the upper movable plate 2 is realized, the adaptability of a part to be welded is further improved, and the part to be welded is convenient to clamp.
The pair of lower movable plates 3 are arranged at intervals along the length direction of the base 1, the middle part of the upper movable plate 2 protrudes upwards, and the protruding part of the upper movable plate 2 is positioned between the pair of lower movable plates 3. A welding space is formed between the protruding parts of the two lower movable plates 3 and the upper movable plate 2, so that welding is facilitated, and the welding efficiency is further improved.
