In order to improve the control precision of the adjustment driving motor 5, the adjustment driving motor 5 may adopt a servo motor.
The clamping drive mechanism 4 includes a base turntable 41, a slide block 42, and a driving bevel gear 43. The base turntable 41 is disc-shaped, the base turntable 41 is rotatably disposed in the spindle base 2, and the base turntable 41 is disposed coaxially with the output end of the spindle driving motor 1. The sliding block 42 is connected to one side of the base turntable 41 through a plane screw thread, so that when the base turntable 41 rotates, the sliding block 42 can be driven to slide along the axial direction of the base turntable 41.
Referring to fig. 3 and 4, the sliding blocks 42 correspond to the adjustment driving motors 5 one by one, and the adjustment driving motors 5 are fixed on the sliding blocks 42, so that when the sliding blocks 42 slide, the adjustment driving motors 5 can drive the clamping unit bodies 31 to slide along a direction close to or far away from the axis of the output end of the spindle driving motor 1; and two sliding blocks 42 are the mode of synchronous motion, can reach the purpose that orders about two clamping unit bodies 31 and be close to each other or keep away from each other to in fix the centre gripping of valve body 7 between two clamping unit bodies 31, and make the axiality of body 71 and the output of spindle drive motor 1 better. The spindle base 2 is provided with a sliding channel 23 for sliding the sliding block 42 and the adjusting driving motor 5.
The driving bevel gear 43 is rotatably disposed on the spindle base 2, and an inner hexagonal sinking groove 431 is disposed at one end of the driving bevel gear 43 away from the tip of the driving bevel gear, so that an operator can drive the driving bevel gear 43 to rotate by using a wrench or other tools. The side of the base turntable 41 away from the sliding block 42 is provided with a gear ring 411 engaged with the driving bevel gear 43, so as to achieve the purpose that the driving bevel gear 43 is driven to rotate, and the base turntable 41 can be driven to rotate. Three driving bevel gears 43 are arranged at equal intervals along the circumferential direction of the basic turntable 41, and the three driving bevel gears 43 can form three-point support for the basic turntable 41, so that the basic turntable 41 can rotate more smoothly; in addition, an operator can drive the basic turntable 41 to rotate at different positions, and the clamping effect of the two clamping unit bodies 31 on the valve body 7 can be improved.
During specific machining, after the valve body 7 is clamped and fixed between the two clamping unit bodies 31, the pipe body 71 is made to be coaxial with the output end of the spindle driving motor 1, then the spindle seat 2 is driven to rotate through the spindle driving motor 1, so that the pipe body 71 rotates around the axis of the pipe body, and one end face of the pipe body 71 and the internal threads of the end portion are machined through a turning tool.
The two clamping unit bodies 31 are driven to rotate in the same direction by adjusting the driving motor 5, and the pipe body 71 is rotated by 90 degrees, so that the communication pipe 73 and the ball valve seat 72 are close to the cutter. Then, the side of the ball valve seat 72 away from the pipe body 71 is machined by a turning tool, and the threaded hole 721 and the inner hole of the communication pipe 73 are machined by a drilling tool.
The two clamping unit bodies 31 are driven to rotate along the same direction by adjusting the driving motor 5, the pipe body 71 is made to rotate for 90 degrees continuously, and then the other end of the pipe body 71 is processed in the same processing mode. In the process of machining the two end parts, the machining axis of the pipe body 71 can be kept unchanged, so that the parallelism between the two end surfaces of the pipe body 71 and the coaxiality between the internal threads at the two ends of the pipe body 71 can be ensured. The steps are simplified, and the operation is convenient.
One end of the clamping unit body 31 for clamping the circular end of the pipe body 71 is provided with a balance weight 6. The regular hexagon end of the pipe body 71 is heavier than the circular end of the pipe body 71, so the balance weight 6 can play a role of balance weight at one end of the circular end of the pipe body 71, the pipe body 71 is not easy to incline towards one end of the regular hexagon end in the processing process, especially when the ball valve seat 72 is processed, the regular hexagon end of the pipe body 71 is arranged at the upper part and the circular end is arranged at the lower part, the gravity center of the pipe body 71 is prevented from moving upwards through the balance weight 6, and the machining size of the pipe body 71 is more accurate. The balance weight 6 may be a rectangular block, and the balance weight 6 may be detachably disposed on the clamping unit body 31, so as to facilitate replacement of the balance weight 6. The detachable connection mode may be a connection mode through a bolt 61, or a connection mode through a pin, and in this embodiment, the bolt 61 is taken as an example.
The circular end of the pipe 71 is held and fixed between the two weights 6, and the guide groove 62 is provided on the side where the two weights 6 are close to each other. The guide groove 62 is an arc-shaped groove with a diameter larger than the outer diameter of the circular end of the tube body 71, i.e. a gap is left between the groove wall of the guide groove 62 and the outer side wall of the circular end of the tube body 71, so as to facilitate the movement of the cutter. The end face of the circular end of the pipe body 71 meets the end face of the regular hexagon end of the pipe body 71, the area of the end face is smaller, the side wall of the pipe body 71 is thinner, and when a turning tool is adopted to process the circular end of the pipe body 71, the uneven surface of the blank of the valve body 7 easily causes the turning tool to generate the phenomenon of tool jump, so that the end face of the pipe body 71 is damaged.
Therefore, when the end face of the circular end of the pipe body 71 is machined, the cutter bar of the cutter can be abutted against the groove wall of the guide groove 62, then the pipe body 71 is driven to rotate, so that the cutter firstly machines a flat technical end face on the circular end of the pipe body 71, and the groove wall of the guide groove 62 can guide and limit the cylindrical cutter bar during machining; after the process end face is processed, the counterweight block is taken down from the clamping unit body 31, and the process end face is further processed. When the cutter is limited and the cutter is machined on the technical end face, the cutter is not easy to jump, so that the accuracy of the machining size of the pipe body 71 is improved. Since the weight 6 needs to be removed when the circular end portion of the pipe body 71 is processed, the circular end portion of the pipe body 71 is finally processed.
The implementation principle of the valve body machining auxiliary device in the embodiment of the application is as follows: during specific machining, the driving bevel gear 43 drives the basic turntable 41 to rotate in the spindle seat 2, and when the basic turntable 41 rotates, the sliding block 42 is driven to slide in the sliding channel 23, so that the purpose of driving the two clamping unit bodies 31 to be away from each other is achieved. Then, the valve body 7 is placed between the two clamping unit bodies 31, and the driving bevel gear 43 is rotated in the reverse direction to move the two clamping unit bodies 31 in the direction to approach each other, thereby clamping and fixing the valve body 7 between the two clamping unit bodies 31. When clamping, the pipe body 71 is positioned in the two clamping grooves 32; the communicating pipe 73 is positioned in the limiting groove 33, and the outer side wall of the communicating pipe 73 is abutted against the chamfer surface; meanwhile, the sides of the two clamping unit bodies 31 close to each other abut against the two sides of the wing plate 74, respectively, so that the valve body 7 is clamped firmly.
After the valve body 7 is clamped and fixed, the regular hexagon end of the pipe body 71 is close to the cutter, then the spindle seat 2 is driven to rotate by the spindle driving motor 1, and the end face and the internal thread of the end are sequentially processed by a turning tool. The two clamping unit bodies 31 are driven to rotate in the same direction by adjusting the driving motor 5, and the pipe body 71 is rotated by 90 degrees, so that the communication pipe 73 and the ball valve seat 72 are close to the cutter. Then, the side of the ball valve seat 72 away from the pipe body 71 is machined by a turning tool, and the threaded hole 721 and the inner hole of the communication pipe 73 are machined by a drilling tool. The two clamping unit bodies 31 are driven to rotate by 90 degrees continuously by adjusting the driving motor 5, so that the circular end of the pipe body 71 is close to the cutter. When the end face of the circular end is processed, the internal thread of the circular end of the pipe body 71 is processed, then the cutter bar of the cutter and the groove wall of the guide groove 62 are processed, and the technical end face is processed on the end face of the circular end of the pipe body 71. The balance weight 6 is then removed from the clamping unit 31 and the technical end face is further processed. The processing steps are simplified, and the operation is convenient.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
