Its technical points include a cylinder part providing driving force, two chucks for clamping objects, and a connecting part connecting the cylinder part and the two chucks; the connecting part includes a wedge mechanism connecting the output shaft of the cylinder part and the two chucks and a slide seat provided on the cylinder part; the wedge mechanism includes an ejection block provided on the output shaft of the cylinder part and two sliders sliding along the slide seat, and the two chucks are respectively provided on the corresponding sliders; the two sliders respectively form a wedge structure with the ejection block, and the two sliders move toward or relative to each other along the slide seat so that the two chucks can realize opening or clamping operations. The utility model improves the precision of positioning clamping, is suitable for firmly clamping small workpieces, ensures the smoothness of clamping or opening, and solves the disadvantage that the existing pneumatic chucks are not suitable for clamping small workpieces due to poor clamping precision.

[0004] At present, most cylinder chuck structures on the market still have certain deficiencies when used.

[0029] See also Figure 1-Figure 6 ,The utility model provides a technical solution: a new unit multi-cylinder chuck structure;

[0030] Embodiment 1:

[0031] In order to solve the problem that the cylinder of the cylinder chuck structure in the prior art needs to reduce accessories to install in a narrow space, the following solution is disclosed. For details, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 :

Through the distribution of multiple groups of fixing mechanisms, the pneumatic cylinder 3 can be installed in multiple positions, reducing the limitations and occupied space when installing the pneumatic cylinder 3. A driving block 301 is rotatably connected to the side of the pneumatic cylinder 3, and an anti-skid mechanism is connected to the surface of the driving block 301. The anti-skid mechanism can prevent the clamping block 4 from loosening during extrusion positioning, thereby improving the stability of the device.

[0033] The fixing mechanism includes a first bolt 202, and the first bolt 202 is threadedly penetrated inside the first threaded hole 201. There are multiple groups of first threaded holes 201 distributed on the surface of the connecting plate 2. When the welding device installs the pneumatic cylinder 3, according to the space requirements inside the device, the pneumatic cylinder 3 is moved to the front or back of the connecting plate 2, and then the cavity on the side of the pneumatic cylinder 3 is aligned with the first threaded hole 201. After the pneumatic cylinder 3 is aligned, the first bolt 202 is moved to the side of the first threaded hole 201 for insertion. When the first bolt 202 is inserted, it can slide through the first threaded hole 201. When the first bolt 202 is inserted into the side of the cavity of the pneumatic cylinder 3, it rotates. When the first bolt 202 rotates, it can threadably slide with the cavity of the pneumatic cylinder 3. When the first bolt 202 thread slides, it can be squeezed and fixed with the connecting plate 2 through the pneumatic cylinder 3, so that the pneumatic cylinder 3 can be reasonably installed according to space requirements.

[0034] Embodiment 2:

[0035] like Figure 1-Figure 5 The technical solution shown in the utility model provides a technical solution: a new unit multi-cylinder chuck structure, which discloses an extrusion groove 304, and the extrusion groove 304 matches the contour of the driving rotating block 301, thereby preventing the rotating frame 302 from slipping when the driving rotating block 301 is running, and improving the stability in the extrusion state to a certain extent:

[0036] The anti-slip mechanism includes a rotating frame 302, and the rotating frame 302 is connected to the surface of the driving rotating block 301, the bottom of the rotating frame 302 is connected to a connecting block 303, and the side of the rotating frame 302 is connected to an anti-wear structure, the bottom of the rotating frame 302 and the top of the connecting block 303 are both provided with an extrusion groove 304, the extrusion groove 304 and the driving rotating block 301 form a fitting connection, the connecting block 303 and the rotating frame 302 are connected through the inside with a second bolt 305, the second bolt 305 and the rotating frame 302 are threadedly connected, and a first extrusion pad 306 is connected between the connecting block 303 and the second bolt 305. Before the pneumatic cylinder 3 of the welding device is used, moving the rotating frame 302 can drive the extrusion groove 304 to move, and when the extrusion groove 304 moves to the side of the driving rotating block 301, the connecting block 303 is moved, and when the connecting block 303 moves to the bottom of the rotating frame 302, the two extrusion grooves 304 can be merged, and then the second screw 305 is moved. The bolt 305 can drive the first extrusion pad 306 to move, and the second bolt 305 can be inserted when it moves to the bottom of the through hole of the connecting block 303. The second bolt 305 can be rotated when it is inserted into the bottom of the cavity of the rotating frame 302 through the through hole of the connecting block 303. When the second bolt 305 rotates, it can slide with the cavity of the rotating frame 302. When the second bolt 305 slides, it can drive the first extrusion pad 306 to move to the bottom of the connecting block 303 for extrusion. When the connecting block 303 is squeezed, it can squeeze the rotating frame 302, thereby driving the two extrusion grooves 304 to squeeze the surface of the driving rotating block 301. When the pneumatic cylinder 3 is running, the driving rotating block 301 can squeeze and rotate the extrusion groove 304. When the extrusion groove 304 is squeezed, it will not slip through the thread fixation of the second bolt 305, thereby preventing loosening when clamping the workpiece, thereby improving the stability of the clamping state of the device.

[0037] Embodiment three:

[0038] like Figure 1 , Figure 2 and Figure 4 The technical solution shown in the utility model provides a technical solution: a new unit multi-cylinder chuck structure, disclosing a second extrusion pad 309, and protecting the clamp block 4 by the second extrusion pad 309, thereby preventing the extrusion wear between the clamp block 4 and other hard parts, and improving the service life of the parts to a certain extent:

[0039] The anti-wear structure includes a fixed block 307, and the fixed block 307 is installed on the side of the rotating frame 302, two extrusion plates 308 are connected to the bottom of the fixed block 307, and a second extrusion pad 309 is connected to the side of the extrusion plate 308, and a clamping block 4 is connected between the second extrusion pads 309, and four groups of second threaded holes 311 are opened through the top of the fixed block 307, and the extrusion plate 308, the second extrusion pad 309 and the clamping block 4 are movably connected through the fourth bolt 310, and the fourth bolt 310 and the second threaded hole 311 form a threaded connection. The clamping block 4 of the welding device is prone to wear due to long-term extrusion and fixation. Moving the extrusion plate 308 can drive the second extrusion pad 309 to move. When the extrusion plate 308 moves to the bottom of the fixed block 307, the clamping block 4 can be moved to the bottom of the second extrusion pad 309 for pressing, and then another group of second extrusion pads 309 can be moved to the bottom of the clamping block 4.

The fourth bolt 310 can be rotated when it is inserted into the bottom of the second threaded hole 311 through the through hole. The fourth bolt 310 can slide through the second threaded hole 311 when it rotates. The fourth bolt 310 can be extruded when it slides to the bottom of the extrusion plate 308. When the extrusion plate 308 is extruded, the clamping block 4 can be extruded through the second extrusion pad 309. The other three fourth bolts 310 are fixed through the second threaded hole 311 in the same way. After the fourth bolt 310 is fixed, the clamping block 4 can be extruded and fixed through the second extrusion pad 309. When the pneumatic cylinder 3 is running, the clamping block 4 can be driven to extrude and position the processing part. When the clamping block 4 is extruded, the extrusion plate 308 can be extruded through the second extrusion pad 309 to prevent the clamping block 4 from directly contacting the extrusion plate 308. The rubber material of the second extrusion pad 309 reduces the wear during the extrusion process and increases the service life of the clamping block 4.
