[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] As Figure 1 and Figure 2 shown, the present utility model provides a milling groove fixture for plate parts, including a workbench 2, and the workbench 2 is horizontally arranged. A guide groove 7 is cut out along the length direction of the workbench 2 at the top of the workbench 2, and two limit blocks are in limiting sliding fit in the guide groove 7, and moving plates 4 are welded to the tops of the two limit blocks. The two moving plates 4 are parallel to each other and are symmetrically arranged left and right along the length direction of the workbench 2, and the plate part is located between the two moving plates 4.

[0020] A first driving assembly is assembled on the workbench 2, and the first driving assembly is in transmission connection with the two moving plates 4. The first driving assembly includes a first motor 1, the first motor 1 is bolted to the workbench 2, and the output shaft of the first motor 1 horizontally penetrates into the workbench 2 along the length direction of the workbench 2 and extends into the guide groove 7. The output shaft of the first motor 1 is rotationally connected to the workbench 2.

[0021] A bidirectional lead screw 8 is horizontally arranged in the guide groove 7 along the length direction of the workbench 2, and the bidirectional lead screw 8 is rotationally connected to the workbench 2. The output shaft of the first motor 1 is coaxially fixedly connected to the bidirectional lead screw 8 for driving the bidirectional lead screw 8 to rotate self. The bidirectional lead screw 8 passes through the two limit blocks and is in threaded connection with the two limit blocks. The two thread sections on the bidirectional lead screw 8 have opposite helix directions, and the two limit blocks correspond to the two thread sections one by one, and the two limit blocks are in threaded connection with the corresponding thread sections. Each moving plate 4 is in threaded connection with the bidirectional lead screw 8 through the connected limit block for driving the two moving plates 4 to slide relatively.

[0022] A second drive assembly is fixedly assembled on each of the two moving plates 4. The second drive assembly includes a second motor 3. Each second motor 3 is bolted to the corresponding moving plate 4 and is either a stepper motor or equipped with a brake device to ensure that the second motor 3 has a self-locking ability. The output shafts of the two second motors 3 are horizontally opposed along the length direction of the workbench 2. The two second motors 3 both horizontally pass through the corresponding moving plate 4 and are rotatably connected to the moving plate 4. Vertically arranged rotating plates 11 are rotatably assembled at the facing ends of the two moving plates 4. The rotating plates 11 are fixedly connected to the output shafts of the second motors 3 on the corresponding moving plates 4 and are used to drive the two rotating plates 11 to rotate in the vertical plane.

[0023] Fixing plates 9 are welded at the same positions corresponding to the opposite faces of the two rotating plates 11. The two fixing plates 9 are arranged oppositely and are both perpendicular to the corresponding rotating plates 11. Clamping plates 10 are slidably assembled at the same positions corresponding to the opposite faces of the two rotating plates 11. The two clamping plates 10 are arranged oppositely and are both perpendicular to the corresponding rotating plates 11. The fixing plates 9 and the clamping plates 10 on the same rotating plate 11 are arranged oppositely and are parallel to each other. The fixing plates 9 and the corresponding clamping plates 10 are clamped in cooperation, and the clamping plates 10 slide close to the fixing plates 9 to clamp the plate members.

[0024] The clamping plates 10 on the rotating plates 11 are in transmission cooperation with the moving plates 4 where the rotating plates 11 are located through a transmission assembly. The transmission assembly includes a first cylinder 5 and a second cylinder 12. The first cylinder 5 is bolted to the rotating plate 11. The output shaft of the first cylinder 5 is fixedly connected to the clamping plate 10 and is perpendicular to the clamping plate 10, and is used to push the clamping plate 10 to slide close to or away from the fixing plate 9.

[0025] The second cylinder 12 is bolted to the workbench 2. A chute 6 is cut along the length direction on the workbench 2. A slider is slidably fitted in the chute 6, and the slider is fixedly connected to the moving plate 4. The output shaft of the second cylinder 12 is arranged along the length direction of the workbench 2 and is fixedly connected to the slider. The moving plate 4 is in transmission connection with the output shaft of the second cylinder 12 through the connected slider.

[0026] Both the first cylinder 5 and the second cylinder 12 are single-acting cylinders and are driven to reset by springs in the cylinder bodies. The cylinder bodies of the first cylinder 5 and the second cylinder 12 are connected through an air pipe, that is, the air inlets / outlets of the first cylinder 5 and the second cylinder 12 are connected through an air pipe, which is used for the air flow in the first cylinder 5 and the second cylinder 12, so as to drive the output shaft of the first cylinder 5 to extend and retract, and further drive the clamping plate 10 to slide close to or away from the fixing plate 9.

[0027] Working principle: When in use, one end of the plate is horizontally placed on one of the fixing plates 9 along the length direction of the workbench 2, and the end of the plate opposite to this end is horizontally placed on the other fixing plate 9 along the length direction of the workbench 2. At this time, the two opposite ends of the plate are both located between the fixing plate 9 and the clamping plate 10.

[0028] Then start the first motor 1. The output shaft of the first motor 1 drives the bidirectional lead screw 8 to rotate. The bidirectional lead screw 8 pushes the two limit blocks to move closer in the guide groove 7. The two limit blocks 7 drive the two moving plates 4 to move closer. The two moving plates 4 drive the two rotating plates 11 to move closer. The two rotating plates 11 drive the two fixing plates 9 to move closer.

[0029] During this process, the two moving plates 4 drive the connected sliders to slide in the chute 6. The sliders push the output shafts of the connected second cylinders 12 to retract. The springs in the second cylinders 12 are stretched. The gas in the second cylinders 12 enters the connected first cylinder 5 through the trachea. The gas in the first cylinder 5 increases and the air pressure increases, thus pushing the output shaft of the first cylinder 5 to extend. The spring in the first cylinder 5 is compressed. The output shaft of the first cylinder 5 drives the connected clamping plate 10 to slide closer to the corresponding fixing plate 9.

[0030] As the two moving plates 4 continue to move closer, the two clamping plates 10 contact the plate and clamp and fix both ends of the plate. During this process, the two moving plates 4 never contact the plate.

[0031] When the milling is completed, start the first motor 1. The output shaft of the first motor 1 rotates in the opposite direction relative to before. The output shaft of the first motor 1 drives the bidirectional lead screw 8 to rotate and pushes the two limit blocks to slide away along the guide groove. The two limit blocks drive the two moving plates 4 to slide away. At the same time, the two moving plates 4 drive the connected sliders to slide in the chute 6. The sliders drive the output shafts of the connected second cylinders 12 to extend. The springs in the second cylinders 12 shorten and reset. The air pressure in the second cylinders 12 decreases. The gas in the first cylinder 5 connected to the second cylinder 12 enters the second cylinder 12 through the trachea. After that, the spring in the first cylinder 5 extends and resets and drives the output shaft of the first cylinder 5 to retract. The output shaft of the first cylinder 5 drives the connected clamping plate 10 to slide away from the plate, releasing the clamping and fixing of the plate.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
