[0015] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0016] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0017] In one embodiment of the present invention, Figure 1-3As shown, an efficient clamping device is provided for clamping bar material 1. It should be noted here that the bar material 1 refers to a steel material with a simple cross-section such as round, square, flat, hexagonal, octagonal, etc., and is delivered in a straight bar. During the processing of the bar material 1, it is often necessary to clamp and fix the bar material 1 through a clamping device so that its upper end surface is on the same horizontal plane to facilitate processing of its end portion. Specifically, the clamping device includes a base 2 and a reference plate 3, a quick-change plate 4 and a pushing mechanism 5 which are sequentially arranged horizontally on the upper surface of the base 2. The rod 1 is vertically inserted into the plate surface of the quick-change plate 4. It should be noted here that the quick-change plate 4 is used to assemble the rod 1. When in use, the rod 1 is first inserted into the socket of the quick-change plate 4. The rod 1 can be loosened or clamped by turning the screw. When loosened, the rod 1 can move freely in the socket. When clamped, the rod 1 is fixed in the socket; the pushing mechanism 5 can be vertically displaced relative to the reference plate 3, and is used to push the upper end face of the rod 1 to the reference plate 3. Thus, under the action of the pushing mechanism 5, the upper end face of the rod 1 can be pushed to the reference plate 3, so that the upper end face of the rod 1 is located on the same horizontal plane, reducing labor requirements and greatly improving production and processing efficiency.

[0018] Specifically, the ejection mechanism 5 includes a first cylinder 51, a sliding assembly 52, and an ejection assembly 53. The sliding assembly 52 is provided with two groups, including a vertical plate 521, a slide rail 522, and a slider 523 arranged opposite each other. The vertical plate 521 is longitudinally arranged on the base 2, the slide rail 522 is fixedly mounted on the vertical plate 521, and the slider 523 is slidably mounted on the slide rail 522. The ejection assembly 53 is fixedly mounted on the slider 523 and maintains synchronous movement with the slider 523. The first cylinder 51 is used to drive the slider 523 to slide longitudinally. As a result, the first cylinder 51 can drive the ejection assembly 53 to shift vertically along the slide rail 522, thereby pushing the bar 1 to the reference surface 3, so that the upper end surface of the bar 1 is located on the same plane, effectively improving the yield rate of the bar 1 processing.

[0019] Furthermore, to accommodate the clamping of bars of varying lengths and mitigate the need for bar length tolerance, the ejector assembly 53 comprises a first fixed plate 531, an ejector base 532, and several ejector pins 533. The first fixed plate 531 is fixed to the slider 523; the ejector base 532 is fixed to the first fixed plate 531 and arranged parallel to the reference plate 3; and the ejector pins 533 are compressibly disposed perpendicularly to the ejector base 532 and aligned with the bar 1, forcing the bar 1 onto the reference plate 3. Because the ejector pins 533 are compressible, they are suitable for machining bars within a certain tolerance range, mitigating the need for bar length tolerance.

[0020] Furthermore, in order to facilitate the assembly of the reference plate 3 and the quick-change plate 5, the clamping device also includes two relatively arranged fixing frames 6. The fixing frame 6 is arranged at one end of the sliding assembly 52, and a first card slot 61 and a second card slot 62 are opened on the opposite side. The first card slot 61 is used to plug in the reference plate 31, so that the reference plate 3 can be detachably set on the base 2; the second card slot 62 is used to plug in the quick-change plate 5, so that the quick-change plate 5 can be detachably set on the base 2.

[0021] Furthermore, in order to make the quick-change plate 4 more stable and avoid shaking when tightening the screws, second cylinders 7 are provided on both sides of the quick-change plate 4. The second cylinders 7 are provided on the fixing frame 6 for clamping the quick-change plate 4.

[0022] Furthermore, in order to increase the stability of the device, a second fixing plate 8 is provided at the other end of the sliding assembly 52 . The second fixing plate 8 is transversely arranged on the base 2 for fixing the first cylinder 51 .

[0023] Furthermore, the clamping device of the present application further includes a buffer member 9 , which is fixedly disposed on the second fixing plate 8 , and an end portion of the buffer member 9 abuts against the first fixing plate 531 , thereby playing a buffering role.

[0024] Furthermore, the clamping device of the present application also includes a first hand-pull valve 10 and a second hand-pull valve 11. The first hand-pull valve 10 is used to control the start and stop of the first cylinder 51, and the second hand-pull valve 11 is used to control the start and stop of the second cylinder 7.

[0025] During use, assemble the rod 1 onto the quick-change plate 4, then insert the quick-change plate 4 into the first slot 61, pull the second hand-pull valve 11 to start the second cylinder 7, lock the quick-change plate 4, and then turn the screw to loosen the rod 1, pull the first manual valve 11 to control the first cylinder 51 to push the upper end surface of the rod 1 to the reference plate 3, turn the screw again to clamp the rod 1, and finally pull the first manual valve 10 and the second manual valve 11 to reset the first cylinder and the second cylinder, take out the interchangeable plate 4 and put it into the machine for processing.

[0026] It should be understood that the present application is not limited to the exact structures that have been described above and shown in the drawings, and that various modifications and changes can be performed without departing from the scope thereof. The scope of the present application is limited only by the appended claims.
