DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] The utility model provides Figure 1 - Figure 4 An ultrasonic pneumatic clamping mechanism shown includes a work station plate 1, a top end of which is provided with a plurality of support shafts 101, and further includes:

[0032] A clamping mechanism, which is sleeved on the outer walls of the plurality of support shafts 101 and is used for clamping and adjusting the size of the central area of ​​the work station plate 1;

[0033] Specifically, the clamping mechanism includes a first clamping jaw 2, a second clamping jaw 3 and a third clamping jaw 4. The first clamping jaw 2 and the second clamping jaw 3 are each provided with three clamping arms, and the third clamping jaw 4 is provided with two clamping arms. The first clamping jaw 2, the second clamping jaw 3 and the third clamping jaw 4 are located on the outer ring of the work station disk 1 and a linkage rod 5 is hinged in sequence between the clamping arms. The other clamping arm of the first clamping jaw 2 is used to connect the driving mechanism. The remaining clamping arm ends of the first clamping jaw 2, the second clamping jaw 3 and the third clamping jaw 4 are close to each other to the center of the work station disk 1, and the clamping arm ends of the first clamping jaw 2, the second clamping jaw 3 and the third clamping jaw 4 located at the center of the work station disk 1 are used to connect the clamping parts.

[0034] It should be noted that the present invention forms a three-axis clamp arm structure through the first clamp 2, the second clamp 3 and the third clamp 4, wherein the end of the first clamp 2, the second clamp 3 and the third clamp 4 used to connect the linkage rod 5 is the longest end of each clamp, which can provide a more effective rotation connection. During the use of the present invention, when one of the clamps rotates, driven by the linkage rod 5, the remaining clamps rotate synchronously. According to the setting of the present invention, the first clamp 2, the second clamp 3 and the third clamp 4 rotate towards each other and away from each other.

[0035] A clamping piece, which is arranged at one end of the clamping claw mechanism located at the center position, and is used to protect the clamping component;

[0036] Specifically, the clamping parts include:

[0037] Connecting columns 9, one end of each of the connecting columns 9 is fixedly connected to the end of the first clamping jaw 2, the second clamping jaw 3 and the third clamping jaw 4 respectively;

[0038] Extrusion ring 10 , multiple extrusion rings 10 are sleeved on the outer wall of the connecting column 9 .

[0039] It should be noted that the extrusion ring 10 can be made of wear-resistant flexible material. After such a configuration, the extrusion ring 10 can protect the workpiece when clamping, thereby enabling the device to protect the workpiece when performing a clamping operation.

[0040] Furthermore, a limiting ring 901 is provided on the outer wall of the connecting column 9, and a plurality of blocking blocks 903 are provided at one end of the connecting column 9 away from the first clamping jaw 2, the second clamping jaw 3 and the third clamping jaw 4. The plurality of blocking blocks 903 cooperate with the limiting ring 901 to clamp and limit the extrusion ring 10.

[0041] Furthermore, fastening bolts 902 are inserted and connected between the connection points of the plurality of blocking blocks 903 and the connection pillars 9 .

[0042] It should be noted that the blocking block 903 cooperates with the limiting ring 901 to limit and clamp the extrusion ring 10. The blocking block 903 is released by tightening the bolts 902, so that the restriction can be removed and the extrusion ring 10 can be replaced, thereby ensuring stability during clamping.

[0043] The driving mechanism is arranged at one side of the work station disc 1 , and the output end of the driving mechanism is connected to the control end of the clamping mechanism. The driving mechanism is used to drive the clamping mechanism to rotate.

[0044] Specifically, the driving mechanism includes:

[0045] A rocker arm 7, a screw rod 701 is provided at the output end of the rocker arm 7, and a connecting piece is provided between the outer wall of the rocker arm 7 and the bottom end of the station plate 1;

[0046] Furthermore, the connecting piece includes:

[0047] A support plate 8, the support plate 8 is fixedly connected to the bottom end of the work station tray 1;

[0048] The connecting buckle plate 801 is sleeved on the outer wall of the rocker arm 7 , and both ends of the connecting buckle plate 801 are fixedly connected to the top of the support plate 8 .

[0049] The support plate 8 supports the rocker arm 7 and is fixed by the connecting buckle plate 801. Under such operation cooperation, the rocker arm 7 will not move. Therefore, during the rotation of the rocker arm 7, the screw rod 701 rotates synchronously with it.

[0050] A connecting sleeve, which is arranged on the outer wall of the screw rod 701;

[0051] The cylinder 6 has one end hinged to the connecting sleeve, and an articulated seat 601 is provided at the output end of the cylinder 6 , and the articulated seat 601 is hinged to a clamping arm of the first clamping jaw 2 .

[0052] Furthermore, the connecting sleeve includes a threaded sleeve 702 , which is threadedly sleeved on the outer wall of the screw rod 701 , and a connecting plate 602 is fixedly connected to one side of the threaded sleeve 702 , and the connecting plate 602 is hinged to the bottom of the cylinder 6 .

[0053] It should be noted that, through the coordination between the threaded sleeve 702 and the screw rod 701, when the screw rod 701 is rotated, with the coordination of the thread, the threaded sleeve 702 follows the rotation direction of the screw rod 701 and moves along the setting direction of the screw rod 701. In the process of movement of the threaded sleeve 702, the connecting plate 602 is driven to move synchronously, so that the cylinder 6 can move synchronously. At the same time, after the output end of the cylinder 6 is connected to the first clamping jaw 2, its output pushes the first clamping jaw 2 to rotate. Since the forward push of the cylinder 6 is stable, the rotation of the first clamping jaw 2 is more uniform, so that each clamping jaw can rotate and clamp more stably.

[0054] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
