It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments.

As shown in fig. 2 and 8, the present invention provides a high-speed processing apparatus for a polygonal curved surface column part, comprising: a supporting seat 001, a rotating platform 002, a driving device, a cutting device 100 and a clamping displacement device 200;

A plurality of clamping and displacing devices 200 are fixed on the rotating platform 002 at intervals and arranged at the same circumference to rotate along with the rotating platform 002, each clamping and displacing device 200 is arranged between the connected protruding parts (flat ring parts) of the profile plates 003, and a cutting device 100 is arranged beside each clamping and displacing device 200, as shown in fig. 8.
Each clamping and position changing device 200 comprises a clamping part for clamping a part to be processed and a shifting part which drives the part to be processed to turn over a certain angle step by step and works independently; the plurality of shifting parts synchronously turn the part to be processed through a synchronous angle adjusting transmission mechanism 400 arranged on the rotary platform 002; the angle alpha of each overturn of the part to be processed is 360 degrees/n, n is the number of the edges of the multi-edge curved surface column part, in the example, n is 6 degrees, and alpha is 60 degrees. The toggle part comprises a toggle rod 310 and a ratchet intermittent mechanism 300; one end of the shifting lever 310 is connected with the ratchet intermittent mechanism 300, and the other end swings under the driving of the synchronous angle modulation transmission mechanism 400; when the shift lever 310 is located at the swing limit position, the ratchet clearance mechanism 300 is shifted to rotate by an angle α, and the ratchet clearance mechanism 300 drives the part to be processed on the clamping portion to turn by the angle α.
The synchronous angle adjusting transmission mechanism 400 comprises a synchronous motor 402, a synchronous transmission belt 401, a plurality of racks 403 and a plurality of transmission mechanisms; each rack 403 is clamped with a driving lever 301; one end of each transmission mechanism is meshed with a rack 403, and the other end of each transmission mechanism is meshed with a synchronous transmission belt 401; the synchronous motor 402 drives the racks 403 to synchronously reciprocate linearly through the transmission mechanism via the synchronous transmission belt 401, and further drives the shift levers 301 to swing. The synchronous angle-adjusting transmission mechanism 400 is fixedly installed on the rotary platform 002, and the synchronous motor 402 is installed at the center of the rotary platform 002 as shown in fig. 2. The transmission mechanism comprises a gear 404, a transmission shaft 405, a synchronous wheel 406 and a bracket 407; the transmission shaft 405 is fixed through a mounting hole preset on the rotary platform 002, one end of the transmission shaft 405 is fixed with a synchronizing wheel 406, the other end is connected with a gear 404, and the gear 404 is meshed with a rack 403 also installed on the rotary platform 002. Meanwhile, a notch groove is formed in the back surface of rack 403 to drive shift lever 301 to swing.
The ratchet intermittent mechanism 300 comprises a ratchet housing 305 connected with the end of a shifting rod 310, a ratchet 302 fixedly connected with the ratchet housing 305, a pawl 304 matched with the ratchet 302, a check pawl 307 for limiting the reverse movement of the ratchet 302, and a pawl spring 303 for resetting the pawl 304; the ratchet 302 is connected with the clamping mechanism through a synchronizing mechanism; the ratchet 302 is provided with 360/a ratchet teeth, in this example 6 ratchet teeth. When the shifting lever 310 swings from the initial position to the limit position, the ratchet casing is driven to rotate by an angle alpha, at the moment, the ratchet wheel synchronously rotates by the angle alpha, the stroke of the ratchet wheel is limited by the pawl and the non-return pawl, and meanwhile, the synchronous mechanism is utilized to drive a part to be processed on the clamping mechanism to turn over by the angle alpha.
The forward and reverse rotation of the synchronous motor 402 in the synchronous angle adjusting transmission mechanism 400 finally causes each gear 404 to rotate clockwise or counterclockwise correspondingly through the power transmission of the synchronous transmission belt 401. And clockwise (counter clockwise) rotation of the gear 404 drives the rack 403 to perform linear reciprocating motion, the direction of which is shown by the arrow in fig. 10. The linear reciprocating motion of rack 403 drives shift lever 301 to swing and reset through the notch groove on the back of rack 403.
In the internal structure of the clamping and displacing device 200, a driving lever 310 is fixedly connected with a ratchet housing 305, and a pawl 304 and a pawl spring 303 are fixedly arranged in the ratchet housing 305; as shown in fig. 6, the ratchet 302 is coaxially coupled to the driving synchronizing wheel 301 through a connecting shaft 306, and the driving synchronizing wheel 301 performs power transmission with the driven synchronizing wheel 206 through the timing belt 207. And the driven synchronizing wheel 206 is connected to the rotating shaft 204. Therefore, when the ratchet 302 rotates a certain angle, the rotating shaft 204 will finally hold the workpiece and rotate the same angle.
In the example of fig. 6, rotation of the gear 404 causes the lever 301 to move in the direction of arrow 1, so that the ratchet housing 305 moves clockwise (as shown), and the clockwise movement of the ratchet housing 305 causes the pawl 304 fixedly mounted therein to move clockwise synchronously while the ratchet 302 is stationary relative to the pawl 304. In this example, adjusting the forward and reverse rotation time of the driving motor 402 will make the shift lever 301 move once along the direction of arrow 1 to drive the ratchet housing 305 to move 60 degrees clockwise, and the pawl 304 installed in the ratchet housing 305 must rotate 60 degrees clockwise synchronously, while in this example, the ratchet 302 has 6 ratchet teeth uniformly distributed, and the angle between the ratchet teeth is 60 degrees, so that the pawl 304 must pass over one ratchet tooth when rotating 60 degrees clockwise synchronously, when the ratchet housing 305 moves clockwise, the curved surface of the pawl 304 rotating along with the curved surface of the ratchet teeth will drive the ratchet 302 to have a tendency of rotating clockwise, but because the existence of the check pawl 306 hinders the clockwise movement of the ratchet 302, the ratchet 302 has only the possibility of rotating counterclockwise as shown in 6. Therefore, the curved surface of the pawl 304 is in contact with the curved surface of the ratchet tooth for a high degree and cannot drive the ratchet wheel 302 to rotate clockwise. Due to the curved surface characteristic of the pawl 304, the pawl spring 303 is compressed, so that the pawl 304 rotates clockwise and lifts upwards simultaneously, curved surface extrusion does not exist after bypassing ratchets, the pawl spring 303 resets and rebounds, the rotating direction of the driving motor 402 is changed, the shifting rod 301 moves along the arrow 2 direction, the ratchet housing 305 moves anticlockwise as a result of action, the pawl 304 rotates one ratchets anticlockwise, the ratchet 302 also rotates 60 degrees anticlockwise, and finally the rotating shaft 204 clamps a workpiece and rotates the same 60 degrees.
In the above analysis, the ratchet shift assembly 200 has two functions:
1. workpieces with different lengths can be clamped and fastened in the machining process; due to the elastic compression of the compression spring 202, the clamping distance between the movable clamp plate 203 and the fixed clamp plate 205 is elastically adjustable, and can adapt to workpieces with different lengths;
2. in the machining process, as long as the shifting lever 301 is driven by the rack to move for a round along the arrows 1 and 2 in sequence, the workpiece rotates by 60 degrees.
The number of the cutting assemblies 100 is 6, the cutting assemblies are arranged outside the supporting seat 001, and the follower rod 105 is flexibly connected with the supporting seat 001 through a tension spring 004. The cutting motor 103 is connected with a cutter 104 and is arranged on the swinging beam 102, the swinging beam 102 is arranged on the fixed upright post 101 and can rotate around the fixed upright post 101 when no external force is restrained. As shown in fig. 2 and 8, since the protrusions and the flat ring portions of the profile plate 003 are alternately arranged, when the profile plate 003 rotates clockwise with the rotating platform 002, the protrusions and the flat ring portions alternately act on the follower rods 105: when the protrusion portion acts on the follower rod 105, the swinging beam 102 swings away from the rotating platform 002 in the direction of arrow 4 in fig. 10 due to the extrusion of the protrusion portion on the follower rod 105, and the tool 104 mounted on the swinging beam 102 also moves away from the rotating platform 002, so that the tool 104 cannot process the workpiece mounted on the ratchet wheel shifting assembly 200, and the tension spring 004 is in a tension state; as the rotary platform 002 rotates, the protruding portion moves away from the follower rod 105 and the flat ring portion starts to approach the follower rod 105, the swinging beam 102 is turned to approach the rotary platform 002 in the direction of arrow 3 in fig. 10 due to the rebound action of the tension spring 004, and the ratchet indexing assembly 200 is mounted at the flat ring portion of the profile plate 003, so that the tool 104 mounted on the swinging beam 102 also approaches the rotary platform 002, and the tool 104 can process the workpiece mounted on the ratchet indexing assembly 200.
In fig. 11, the cutting assemblies 100 are arranged at intervals of 50 degrees by taking the rotary platform 002 as a central axis, so that the follower rods 105 on each cutting assembly 100 can synchronously move away from or contact with the protruding part and the flat ring part, and therefore, the 6 cutters 104 synchronously contact 6 workpieces to be machined or finish machining away from the workpieces.
The working process is as follows:
1. before the apparatus is started, the follower bar 105 of each cutting assembly 100 is in direct contact with the protrusions on the profile plate 003, as shown in FIG. 12; at this time, the pressing of the follower lever 105 by the projecting portion causes the swing beam 102 to be away from the rotary table 002, the cutter 104 mounted on the swing beam 102 is also away from the rotary table 002,
respectively installing the blanks on 6 ratchet wheel displacement assemblies 200, and starting a speed reducing motor 008 and a cutting motor 103 to drive a driving gear 006 and a cutter 104 to rotate;
2. due to the gear engagement transmission, the driving gear 006 drives the driven gear 005 to start rotating, and further drives the rotating platform 002, the profile plate 003 and each ratchet wheel deflection assembly 200 arranged on the rotating platform 002 to integrally rotate;
3. before starting; the follower rods 105 of the cutting assemblies 100 are in direct contact with the protruding parts of the profile plates 003, the protruding parts press the follower rods 105 to enable the swinging beam 102 to be far away from the rotating platform 002, the cutter 104 mounted on the swinging beam 102 is also far away from the rotating platform 002, and the protruding parts are not provided with the ratchet wheel displacement assemblies 200, so that the cutter 104 does not need to be subjected to cutting processing, and the tension springs 004 are in a stretching state;
4. the rotation of the rotary platform 002 in the horizontal direction continues, the 6 flat ring parts on the profile plate 003 are all gradually close to the 6 follower rods 105, and due to the resilience of the 6 tension springs 004, the 6 swinging cross beams 102 and the respective cutters 104 in the rotating state are also close to and machine-cut the workpiece blank clamped by the 6 ratchet deflection assemblies 200 just installed at the flat ring parts of the profile plate 003. The 6 cutters 104 simultaneously perform cutting on 6 corresponding workpiece blanks, and because the workpiece blanks are driven by the rotary platform 002 to rotate all the time in the cutting process, the cut processing surface is a curved surface;
5. meanwhile, after the first knife is machined, the rotating platform 002 continues to rotate, the contact part of the follower rod 105 and the profile plate 003 at the 6 positions is transited from the flat ring part to the protruding part, and in the process, the forward and reverse rotation of the driving motor 402 in the synchronous angle modulation transmission mechanism 400 finally enables each gear 404 to correspondingly rotate clockwise or anticlockwise through the power transmission of the synchronous transmission belt 401. And clockwise (counter clockwise) rotation of the gear 404 drives the rack 403 to perform linear reciprocating motion. The linear reciprocating motion of rack 403 drives shift lever 301 to rotate and reset through the notch groove on the back of rack 403. Then, 6 workpieces are simultaneously rotated by 60 degrees through the ratchet intermittent angle adjusting mechanism 300;
6. with the rotation of the rotary platform 002, the 6 flat ring parts on the profile plate 003 are all gradually close to the 6 follower rods 105 respectively, the steps 4, 5 and 6 are repeated in sequence, and after the rotary platform 002 rotates for a circle, each cutter 104 sequentially carries out primary curved surface processing on 6 workpiece blanks clamped by the 6 ratchet wheel deflection assemblies 200; 6-36 curved surfaces are machined by 6 cutters;
