[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0030] Embodiment 1

[0031] like Figure 1-4 A clamping device is shown, the clamping device comprises a mounting block 1, a driving member 2, a first connecting plate 31, a second connecting plate 32, a first clamping member 3 and a second clamping member 4, the driving member 2 is a two-finger cylinder, a slide groove 11 is provided on the bottom of the mounting block 1, the two-finger cylinder is fixed on the top of the mounting block 1, a slider 21 on the two-finger cylinder is arranged in the slide groove 11 and reciprocates along the slide groove 11, the first connecting plate 31 and the second connecting plate 32 are respectively fixed on the two sliders 21, and can be driven by the sliders 21 to move synchronously, and the first clamping member 3 and the second clamping member 4 are moved along the thickness of the connecting plate. The first clamping member 3 includes a first clamping block 34 and a second clamping block 35, which are fixedly connected to the first connecting plate 31 and the second connecting plate 32, respectively. The second clamping member 4 includes a third clamping block 41 and a fourth clamping block 42, which are fixedly connected to the first clamping block 34 and the second clamping block 35, respectively. The first clamping block 34 and the second clamping block 35 are moved closer to each other to clamp the hose under the action of the driving member 2, and can synchronously drive the third clamping block 41 and the fourth clamping block 42 to move closer to each other to clamp the hose. The first clamping member 3 of the present application can clamp a slightly shorter hose alone, or it can clamp the hose together with the second clamping member 4. This design realizes a clamping device that can stably clamp and transfer hoses of various lengths to prevent the hoses from hanging.

[0032] The first clamping block 34 and the second clamping block 35 are flat as a whole, and the specific structure is divided into three sections including a first connecting portion 341, a first fixing portion 342 and a first clamping portion 343, and the three are integrally formed. The first connecting portion 341 and the first clamping portion 343 are respectively located on the two side surfaces where the thickness and length of the first fixing portion 342 are located and are both arranged perpendicular to the first fixing portion 342. The first connecting portion 341 is arranged upward, and the first clamping portion 343 is arranged downward, that is, the first connecting portion 341 and the first clamping portion 343 are facing each other, the clamping surface is located on the first clamping portion 343, and the first connecting portion 341 is fixed on the side of the connecting plate. The specific connecting plate is provided with bolt holes, and the first connecting part 341 also has corresponding holes for the bolt holes. Bolts are inserted into the above holes in sequence for locking and fixing. After locking, the inner side of the first connecting part 341 is against the surface of the connecting plate, and the two side surfaces of the first connecting part 341 and the two side surfaces of the connecting plate are against each other for support. The connection strength of this design is very high, so that the entire first clamping block 34 and the second clamping block 35 are very stable when they are subsequently used to clamp the hose. In this embodiment, the first fixing part 342 faces the side where the connecting plate is located and extends to the bottom of the connecting plate, and the first clamping part 343 is located below the bottom of the connecting plate. The first fixing part 342 extends toward the bottom of the connecting plate so that the first clamping part 343 is at the bottom of the connecting plate. In this design, the entire clamping end and the driving end are set up and move together, which is suitable for workstations with unlimited head space.

[0033] The first connecting plate 31 is movably arranged on the second connecting plate 32 through a sliding member 33. Specifically, a slide rail is arranged at one end of the first connecting plate 31 and a slider is arranged at the other end, a slider is arranged at one end of the second connecting plate 32 corresponding to the slide rail on one end of the first connecting plate 31, and a slide rail is arranged at the other end corresponding to the slider on one end of the first connecting plate 31, and the slide groove extends in the horizontal direction, and the slider is clamped in the slide groove and slidably cooperates with the slide groove, so that the first connecting plate 31 or the second connecting plate 32 moves along the extension direction of the slide groove, thereby controlling the first clamping block 34 and the second clamping block 35 to approach or move away from each other, thereby completing the operation of taking and placing the hose.

[0034] The third clamping block 41 and the fourth clamping block 42 are all flat in shape. The specific structure is divided into three sections, including the second connecting portion 411, the second fixing portion 412 and the second clamping portion 413, and the three are integrally formed. The second connecting portion 411 and the second clamping portion 413 are respectively located on the two side surfaces where the thickness and length of the second fixing portion 412 are located and are both arranged perpendicular to the second fixing portion 412. The second clamping portion 413 is arranged downward, and the second connecting portion 411 can be arranged upward or downward, as long as the second connecting portion 411 can be fixed on the side of the first fixing portion 342. The first fixing portion 342 is provided with bolt holes, and the second connecting portion 411 also has corresponding bolt hole positions. Bolts are inserted into the above-mentioned holes in sequence for locking and fixing. After locking, the inner side surface of the second connecting portion 411 is against the surface of the first fixing portion 342. The connection strength of this design is very high, so that the entire second clamping member 4 and the first clamping member 3 are very stable when they are subsequently used to clamp the hose.

[0035] The third clamping block 41 and the fourth clamping block 42 of the present application can be disassembled and replaced according to the length requirements of the hose, and can adapt to the assembly of hoses of various lengths.

[0036] There are at least three first clamping parts 343 on the lower side of the first fixing part 342. The multiple first clamping parts 343 are distributed along the thickness direction of the connecting plate, two of which are located at the two ends of the first fixing part 342, and the rest are located between the first clamping parts 343 at the two ends. The first clamping parts 343 on the first clamping block 34 and the second clamping block 35 are arranged in pairs in parallel. The first clamping parts 343 arranged at the two ends can clamp the ends of the hose, and the rest clamp the middle of the hose, so that the multiple clamping effects are better and more stable. Moreover, the main purpose of such a design is to have a spacing between the two first clamping parts 343 in coordination with the carrier, so that after the hose is grasped at multiple locations, the hose at the spacing can be correspondingly clamped into the carrier through the movement of the entire clamping device to enter the next tool for processing, and can be adapted to the carrier plate, which not only has high clamping stability, but also is easy to move and adapt.

[0037] Furthermore, the first clamping member 3 and the second clamping member 4 are provided in plurality and are arranged in a one-to-one correspondence, and the plurality of the first clamping members 3 and the second clamping members 4 are distributed along the length direction of the connecting plate. Multiple groups of the first clamping members 3 can clamp the hose alone or in conjunction with the second clamping member 4. This design greatly improves the feeding efficiency and the assembly efficiency.

[0038] Furthermore, the first clamping block 34 and the second clamping block 35 are also provided with a fixing plate 345, which is fixedly connected to a plurality of first clamping portions 343 distributed along the length direction of the connecting plate on the first clamping block 34 and the second clamping block 35. The number of the fixing plates 345 corresponds to the number of the first clamping portions 343 distributed along the thickness direction of the connecting plate. This design ensures that the hose is in a horizontal and straight state when the first clamping block 34 and the second clamping block 35 support and transfer the hose, and the hose will not tilt or bend, thereby further improving the stability and pass rate of feeding and assembly.

[0039] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
