Detailed Embodiments

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] As Figures 1 to 6 shown, a fixture structure for rotary machining includes a bottom plate 1. A fixed frame 2 is fixedly connected to the upper side of the bottom plate 1. Two smooth rods 3 are connected inside the fixed frame 2. Two slide plates 4 are respectively slidably connected to the outer surfaces of the two smooth rods 3. A first telescopic slide base 5 and a second telescopic slide base 7 are respectively slidably connected to one side of the two slide plates 4. A second cross-shaped block 9 is clamped on the upper side of the second telescopic slide base 7. A first cross-shaped block 8 is clamped on the upper side of the first telescopic slide base 5.

[0028] A first fixture rotating seat 12 is rotatably installed on the left side of the first cross-shaped block 8. A second fixture rotating seat 13 is rotatably installed on the right side of the second cross-shaped block 9. Through the settings of the first cross-shaped block 8 and the second cross-shaped block 9, the two cross-shaped blocks can play a role in stable clamping to fix the two fixture rotating seats. The right side of the first fixture rotating seat 12 is fixedly connected to a first servo motor 14 through a motor mounting plate. Through the setting of the first servo motor 14, the workpiece is fixed on the two fixture rotating seats. In this way, the output shaft of the first servo motor 14 can drive the workpiece on the two fixture rotating seats to rotate, so as to realize rotary machining, which is convenient to use. Limited activity plates 10 are rotatably connected to the upper sides of the first telescopic slide base 5 and the second telescopic slide base 7. Positioning rods 11 are slidably clamped on the upper sides of the two limited activity plates 10.

[0029] First springs 6 are arrayed and connected between the first telescopic slide base 5, the second telescopic slide base 7 and the slide plate 4 respectively. First clamping plates 15 are installed at the bottom ends inside the first fixture rotating seat 12 and the second fixture rotating seat 13. Electric push rods 16 are fixedly connected to the top ends inside the first fixture rotating seat 12 and the second fixture rotating seat 13. The model of the electric push rod 16 is HB-DJ801. Second clamping plates 17 are fixedly installed on the lower sides of the two electric push rods 16. Rubber pads 18 are connected to the inner sides of the first clamping plates 15 and the second clamping plates 17. The rubber pads 18 can increase the friction with the workpiece. Then, the electric push rods 16 can drive the second clamping plates 17 to clamp the workpiece on the first clamping plates 15, so as to stably position the position of the workpiece.

[0030] On one side of the first telescopic sliding seat 5 and the second telescopic sliding seat 7, two L-shaped plates 19 are connected. On one side of the four L-shaped plates 19, telescopic insertion rods 20 are slidably connected. The telescopic insertion rods 20 are used to fix the first cross-shaped block 8 and the second cross-shaped block 9. One side of the telescopic insertion rod 20 penetrates through the L-shaped plate 19 and extends to the other side of the L-shaped plate 19. A second spring 21 is connected between the four telescopic insertion rods 20 and the L-shaped plate 19 together.

[0031] A threaded rotating rod 22 is rotatably connected inside the fixing frame 2. Two connecting plates 24 are threadedly connected to the outer surface of the threaded rotating rod 22. Through the arrangement of the smooth rods 3, the movement trajectories of the connecting plates 24 and the sliding plate 4 can be restricted by the two smooth rods 3, so that the two can move back and forth smoothly. This can be used to clamp workpieces of different specifications and improve the adaptability of the fixture structure. On the upper sides of the two connecting plates 24, sliding plates 4 are installed. The left side of the threaded rotating rod 22 penetrates through the fixing frame 2 and extends to the left side of the fixing frame 2. The left side of the threaded rotating rod 22 is fixedly connected to a second servo motor 23 through a motor mounting plate.

[0032] Two support plates 25 are fixedly installed on the upper side of the fixing frame 2. Two round rods 26 are connected to the inner sides of the two support plates 25. A clamping plate 27 is slidably clamped on the outer surfaces of the two round rods 26. A rubber block 29 is installed on the inner side of the clamping plate 27. Tightening bolts 28 are threadedly connected to both ends of the clamping plate 27. The tightening bolts 28 are used to fix the clamping plate 27.

[0033] One side of the first telescopic sliding seat 5 and the second telescopic sliding seat 7 penetrates through the sliding plate 4 and extends to the other side of the sliding plate 4. The lower side of the positioning rod 11 penetrates through the limit movable plate 10 and extends to the upper sides of the first telescopic sliding seat 5 and the second telescopic sliding seat 7. The limit movable plate 10 is used to fix the first cross-shaped block 8 and the second cross-shaped block 9.

[0034] The working principle of a fixture structure for rotary machining provided by the present utility model is as follows:

[0035] By successively clamping the first cross-shaped clamping block 8 and the second cross-shaped clamping block 9 into the first telescopic sliding seat 5 and the second telescopic sliding seat 7, then pulling the telescopic insertion rod 20 equipped with the second spring 21, the elastic telescopic insertion rod 20 can be contracted. In this way, the two cross-shaped clamping blocks can drive the first fixture rotating seat 12 and the second fixture rotating seat 13 to be initially clamped and fixed. Subsequently, releasing the telescopic insertion rod 20, the telescopic insertion rod 20 will automatically clamp the telescopic sliding seat and the cross-shaped clamping block to further fix the two cross-shaped clamping blocks. Then, rotate the two limit movable plates 10 to the positions of the first cross-shaped clamping block 8 and the second cross-shaped clamping block 9 respectively, and insert the positioning rod 11 into the telescopic sliding seat and the limit movable plates 10 to stably limit the two cross-shaped clamping blocks, ensuring the stability when the first fixture rotating seat 12 and the second fixture rotating seat 13 are clamped. In this way, different specifications of fixtures can be flexibly replaced by clamping, without having to replace other fixtures for processing, thus expanding the applicable range of the fixture structure and improving the processing efficiency when using the fixture structure.

[0036] By driving the threaded rotating rod 22 to rotate through the output shaft of the second servo motor 23, at this moment, the two connecting plates 24 on the threaded rotating rod 22 can move towards each other, enabling the two connecting plates 24 to drive the first telescopic sliding seat 5 and the second telescopic sliding seat 7 equipped with the first spring 6 to slowly approach each other. In this way, the first fixture rotating seat 12 and the second fixture rotating seat 13 can flexibly adjust the clamping distance to better adapt to workpieces of different lengths. At the same time, the two elastic fixture rotating seats can also play a buffering role to weaken the clamping force in order to protect the workpiece on the fixture. Then, move the two clamping plates 27 on the round rod 26 so that the rubber blocks 29 at the two clamping plates 27 can fit and clamp the front and back sides of the workpiece, and then use the fastening bolts 28 to fix the two clamping plates 27 to further position the workpiece, enabling the workpiece to be processed stably and reliably.

[0037] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
