Description

Technical Field

[0001] The present invention relates to the technical field of cutting processing, and particularly relates to an automatic cutting device for a regulating valve assembly. Background Art

[0002] The regulating valve assembly mainly consists of a valve body, a valve core, a valve stem, etc. Among them, the valve stem is one of the crucial metal components in the regulating valve and plays an important role in the normal operation and performance of the regulating valve; and the valve stem is usually processed by cutting a cemented carbide rod and then performing turning, milling, heat treatment and other steps.

[0003] The cutting method of the cemented carbide rod is usually to first fix a single cemented carbide rod or multiple cemented carbide rods through a fixture, and then sequentially cut the cemented carbide rod through a cutting blade. After cutting, the fixture is loosened, the cemented carbide rod is moved to the required cutting length, and then cutting processing is performed again.

[0004] However, the current cemented carbide rods have the following problems during cutting: During cutting, it is necessary to manually operate the fixture frequently to clamp and loosen the cemented carbide rod, resulting in low processing efficiency. And since the cemented carbide rods are cut sequentially, after each cemented carbide rod is cut, the cutting blade will rotate idly, move a certain distance and then cut the next cemented carbide rod, further reducing the overall efficiency of the cutting processing of the cemented carbide rod.

[0035] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0036] As Figure 1 shown, an automatic cutting device for a regulating valve assembly includes an equipment rack 10; a bottom plate 11 is installed on the equipment rack 10, and a cutting mechanism 3 and a fixing mechanism 2 are arranged on the bottom plate 11.

[0037] As Figure 1 and Figure 2As shown, the fixing mechanism 2 includes a first support. The first support is installed at the upper end of the bottom plate 11 on the right side of the cutting mechanism 3. A first fixing ring 20 is installed on the first support. First positioning blocks 21 are uniformly arranged along the circumferential direction of the inner ring surface of the first fixing ring 20. First through holes 22 are formed in the first positioning blocks 21. The first positioning blocks 21 slide along the radial direction of the first fixing ring 20 through first guide rods 23, and the first guide rods 23 penetrate through the first fixing ring 20.

[0038] As Figure 1 , Figure 3 and Figure 5 shown, the cutting mechanism 3 includes a fixed seat 30. The fixed seat 30 is installed at the upper end of the bottom plate 11. A rotating pipe 31 is rotatably installed on the fixed seat 30. A cutting tool 32 is installed at the right end of the rotating pipe 31. A first motor 33 for driving the rotating pipe 31 to rotate is installed at the lower end of the bottom plate 11. A liquid spraying part 34 for spraying cutting fluid is installed on the fixed seat 30.

[0039] As Figure 1 , Figure 2 and Figure 8 shown, a clamping part 24 for fixing the cemented carbide rod is arranged on the first positioning block 21. A feeding part 25 for pushing the cemented carbide rod to feed for cutting is arranged on the bottom plate 11 on the right side of the first fixing ring 20. A fixing part 26 for fixing the left end of the cemented carbide rod is also arranged on the bottom plate 11 on the left side of the cutting tool 32. A pushing and pulling part 8 for driving the first positioning block 21, the feeding part 25 and the fixing part 26 is arranged on the rotating pipe 31.

[0040] During specific operation, an operator sequentially inserts the cemented carbide rods from right to left through the feeding part 25 and the clamping part 24, so that a plurality of cemented carbide rods are distributed along the circumferential direction of the cutting tool 3. Then, the feeding part 25 first fixes the right end of the cemented carbide rod, and then the feeding part 25 pushes the cemented carbide rod to move leftward until it reaches the required cutting position. At the same time, the left end of the cemented carbide rod is inserted into the corresponding fixing part 26. Then, the pushing and pulling part 8 drives the clamping part 24 and the fixing part 26 to fix the cemented carbide rod to improve the stability of the cutting of the cemented carbide rod. After the cemented carbide rod is fixed, the first motor 33 drives the rotating pipe 31 to rotate, the rotating pipe 31 drives the cutting tool 32 to rotate, and at the same time, the liquid spraying part 34 sprays cutting fluid onto the cutting tool 32. Then, the pushed and pulled cemented carbide rod is pulled by the pushing and pulling part 8 to move towards the cutting tool 32, so that a plurality of cemented carbide rods are cut simultaneously to improve the overall processing efficiency of the cemented carbide rod. After the cemented carbide rod is cut off, the first motor 33 stops driving the cutting tool 32 to rotate. Then, the pushing and pulling part 8 pushes the cemented carbide rod away from the cutting tool 32. Then, the feeding part 25 pushes the cemented carbide rod to move leftward to the required cutting position again, and at the same time, pushes the cut-off cemented carbide rod to move leftward to disengage from the fixing part 26, so that the fixing part 26 can fix the cemented carbide rod to be cut later.

[0041] As Figure 1 and Figure 2 shown, the material pushing part 25 includes a chute. A chute is formed on the bottom plate 11. A lead screw 250 is rotatably installed in the chute. A second motor 251 for driving the lead screw 250 is installed at the lower end of the bottom plate 11. A base 252 is threadedly connected to the lead screw 250, and the base 252 is slidably installed in the chute. A second fixing ring 253 is installed on the base 252. Second positioning blocks 254 are uniformly arranged along the circumferential direction of the inner ring surface of the second fixing ring 253. Second guide rods 255 are arranged on the second positioning blocks 254 to slide radially along the second fixing ring 253, and the second guide rods 255 penetrate through the second fixing ring 253. Second through holes 256 are formed on the second positioning blocks 254. A positioning member 4 for clamping the right end of the cemented carbide bar is arranged on the second positioning blocks 254.

[0042] As Figure 1 、 Figure 2 、 Figure 6 and Figure 8 shown, the positioning member 4 includes a second installation groove. A second installation groove communicating with the second through hole 256 is formed in the second positioning block 254. Second clamping blocks 40 distributed along the circumferential direction of the second through hole 256 are slidably installed in the second installation groove. A second gear disk 41 is rotatably installed in the second installation groove. Second arc grooves 42 corresponding to the second clamping blocks 40 are formed on the second gear disk 41. Second roller shafts 43 slidably penetrating through the corresponding second arc grooves 42 are installed on the second clamping blocks 40. A second spline shaft 44 is rotatably installed on the second positioning block 254. A spline sleeve 45 is slidably installed on the second spline shaft 44, and the spline sleeve 45 is rotatably installed on the second fixing ring 253. A first bevel gear 46 meshing with the corresponding second gear disk 41 is installed on the second spline shaft 44. An actuator 5 for driving the second spline shaft 44 to rotate is arranged on the second fixing ring 253.

[0043] As Figure 1 、 Figure 2 and Figure 6 shown, the actuator 5 includes a third bevel gear 50. The third bevel gear 50 is installed on the spline sleeve 45 and located outside the second fixing ring 253. A toothed ring 51 meshing with the third bevel gear 50 is rotatably installed on the second fixing ring 253. A fourth motor 52 for driving one of the spline sleeves 45 to rotate is installed on the base 252.

[0044] During specific operation, after manually placing multiple cemented carbide rods, the fourth motor 52 drives one of the spline sleeves 45 to rotate. The rotating spline sleeve 45 drives the gear ring 51 to rotate through the corresponding third bevel gear 50. The gear ring 51 then drives the remaining third bevel gears 50 to rotate synchronously. The third bevel gears 50 drive the corresponding first bevel gears 46 to rotate through the second spline shaft 44. The first bevel gears 46 drive the corresponding second toothed discs 41 to rotate. The second toothed disc 41, through the cooperation of the second arc-shaped groove 42 and the corresponding second roller shaft 43, makes the second clamping block 40 move towards the cemented carbide rod to clamp and fix the cemented carbide rod. Then, the second motor 251 drives the lead screw 250 to rotate. The lead screw 250 drives the base 252 to move leftward. The base 252 drives the fixed cemented carbide rod to move leftward. After the left end of the cemented carbide rod moves to the required cutting position, the fixing part 26 and the clamping part 24 clamp and fix the cemented carbide rod. Then, the pushing and pulling part 8 pulls the second positioning block 254 towards the center of the second fixing ring 253, so that multiple cemented carbide rods move towards the cutting tool 32 synchronously to cut multiple cemented carbide rods simultaneously.

[0045] After the cemented carbide rod is cut, the pushing and pulling part 8 pushes the cemented carbide rod away from the center of the second fixing ring 253. Then, the fixing part 26 and the clamping part 24 release the clamping and fixing of the cemented carbide rod, while the second clamping block 40 maintains the clamping and fixing of the cemented carbide rod. Then, the second motor 251 drives the lead screw 250 to rotate again. The lead screw 250 then pushes the left end of the cemented carbide rod to move to the required cutting position again. After that, the above operations are repeated to cut the cemented carbide rod again.

[0046] As Figure 7 and Figure 8 shown, the clamping part 24 includes a first installation groove. A first installation groove communicating with the first through hole 22 is formed in the first positioning block 21. A first clamping block 240 distributed circumferentially along the first through hole 22 is slidably installed in the first installation groove. A first toothed disc 241 is rotatably installed in the first installation groove. First arc-shaped grooves 242 corresponding to the first clamping blocks 240 are formed on the first toothed disc 241. A first roller shaft 243 slidably penetrating the corresponding first arc-shaped groove 242 is installed on the first clamping block 240.

[0047] As Figure 1 、 Figure 2 and Figure 3As shown, the fixing part 26 includes a second support. A second support is installed at the upper end of the bottom plate 11. A fixing cylinder 260 with an open right end is installed on the second support. Third positioning blocks 261 are evenly and slidably installed on the fixing cylinder 260 along its circumferential direction. Connecting rods 262 are installed between the third positioning blocks 261 and the corresponding first positioning blocks 21. Waist slots 263 corresponding to the third positioning blocks 261 are opened at the left end of the fixing cylinder 260. Third through holes 264 are opened on the third positioning blocks 261. A limiting member 6 for clamping the cemented carbide rod is arranged in the third through holes 264.

[0048] As Figure 2 、 Figure 7 and Figure 8 shown, the limiting member 6 includes a third installation groove. A third installation groove communicating with the third through hole 264 is opened in the third positioning block 261. Third clamping blocks 60 distributed along the circumferential direction of the third through hole 264 are slidably installed in the third installation groove. A third gear disk 61 is rotatably installed in the third installation groove. Third arc grooves 62 corresponding to the third clamping blocks 60 are opened on the third gear disk 61. Third roller shafts 63 slidably penetrating through the corresponding third arc grooves 62 are installed on the third clamping blocks 60. Driving members 7 for driving the corresponding third gear disks 61 and first gear disks 241 to rotate are arranged on both the fixing cylinder 260 and the first fixing ring 20.

[0049] As Figure 1 、 Figure 2 and Figure 5 shown, the pushing and pulling part 8 includes a support rod 80. A support rod 80 is rotatably installed in the middle of the rotating pipe 31. The right end of the support rod 80 penetrates through the fixed pipe 340 and then a first spline shaft 81 is installed. A driving disk 82 is slidably installed at the corresponding positions of the first spline shaft 81, the first fixing ring 20 and the second fixing ring 253. Connecting rods 83 are hinged between the driving disk 82 and the corresponding first positioning blocks 21 and second positioning blocks 254. A third motor 84 for driving the support rod 80 to rotate is installed at the lower end of the bottom plate 11.

[0050] During specific operation, the third motor 84 drives the support rod 80 to rotate. The support rod 80 drives the driving disk 82 to rotate through the first spline shaft 81. The driving disk 82 pulls the first positioning block 21 and the second positioning block 254 to move towards the center of the cutting tool 32 through the connecting rods 83. The first positioning block 21 drives the third positioning block 261 to move synchronously through the connecting rod 262. During the movement of the first positioning block 21 and the third positioning block 261, the corresponding first gear disk 241 and third gear disk 61 are driven to rotate through the driving member 7. The first gear disk 241 and the third gear disk 61 push the corresponding first roller shafts 243 and third roller shafts 63 to move through the corresponding first arc grooves 242 and third arc grooves 62, so that the corresponding first clamping blocks 240 and third clamping blocks 60 move towards the cemented carbide rod to squeeze and fix the corresponding cemented carbide rod.

[0051] After the first cutting of the cemented carbide rod is completed, the No. 3 motor 84 drives the support rod 80 to rotate in the reverse direction. The support rod 80 then drives the drive disk 82 to rotate in the reverse direction through the first spline shaft 81, so as to push the first positioning block 21, the third positioning block 261, and the second positioning block 254 away from the center of the cutting tool 32 through the connecting rod 83. During the movement of the first positioning block 21 and the third positioning block 261, the first clamping block 240 and the third clamping block 60 are driven away from the cemented carbide rod through the driving member 7 to release the clamping and fixing of the cemented carbide rod. Then, the feeding part 25 pushes the cemented carbide rod to move leftward to the required cutting position, and then the above operation is repeated to clamp, fix, and cut the cemented carbide rod again.

[0052] As Figure 2 、 Figure 3 、 Figure 4 and Figure 7 As shown in the figure, the driving member 7 includes a shaft rod 70. The shaft rod 70 is rotatably installed on both the third positioning block 261 and the first positioning block 21. A second bevel gear 71 meshing with the corresponding third gear disk 61 and the first gear disk 241 is installed on the shaft rod 70. The shaft rod 70 slidably penetrates through the corresponding fixed cylinder 260 and the first fixing ring 20. A guide groove 72 is formed on the shaft rod 70. The guide groove 72 is composed of a straight section and an arc section. Guide posts 73 corresponding to the corresponding guide grooves 72 are installed on both the fixed cylinder 260 and the first fixing ring 20.

[0053] As Figure 3 and Figure 5 As shown in the figure, the liquid spraying part 34 includes a fixed pipe 340. The right end of the fixed seat 30 is installed with a liquid storage box 341 located on the left side of the cutting tool 32 through the fixed pipe 340. The fixed pipe 340 is communicated with the liquid storage box 341. The right end of the liquid storage box 341 is communicated with a nozzle 342 corresponding to the first positioning block 21. A liquid inlet pipe 343 is communicated with one of the fixed pipes 340.

[0054] During specific operation, when the connecting rod 83 pulls the first positioning block 21 and the third positioning block 261 to move towards the cutting tool 32, under the guidance of the arc section of the guiding groove 72 and the limitation of the guiding post 73, the shaft rod 70 rotates by a certain angle. The shaft rod 70 then drives the corresponding third gear disk 61 and the first gear disk 241 to rotate through the second bevel gear 71, so as to drive the corresponding third clamping block 60 and the first clamping block 240 to clamp and fix the cemented carbide rod. Then, as the first positioning block 21 and the third positioning block 261 move, the straight section of the guiding groove 72 cooperates with the guiding post 73 to limit the rotation of the shaft rod 70, so as to maintain the state where the third clamping block 60 and the first clamping block 240 clamp and fix the cemented carbide rod. After that, the first positioning block 21 and the third positioning block 261 drive the fixed cemented carbide rod to move towards the cutting tool 32 for cutting. At the same time, an external water pump is connected to the liquid inlet pipe 343 through an external conveying pipe, and conveys the cutting fluid through the liquid inlet pipe 343 and the fixed pipe 340 to the liquid storage box 341. As the cutting fluid in the liquid storage box 341 increases, the pressure increases, causing the cutting fluid to spray from the nozzle 342 towards the cutting part of the cemented carbide rod, so as to play a role in cooling and protecting the cutting tool 32 and cleaning debris to ensure the smoothness and quality of cutting.

[0055] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be understood as a limitation on the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0056] In addition, the terms "first", "second", "first one", "second one" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features.
