[0031] Reference Figure 1 and Figure 2 A five-axis mechanical swing head includes a base 1, a tool mechanism 2 arranged on the base 1, a transmission mechanism 3 for driving the tool mechanism 2, an A-axis indexing mechanism 4, and a C-axis indexing mechanism 5. When the five-axis mechanical swing head is in operation, the A-axis indexing mechanism 4 and the C-axis indexing mechanism 5 respectively drive the tool mechanism 2 to swing or rotate in the A-axis and C-axis directions for indexing. After the indexing is completed, the transmission mechanism 3 drives the tool mechanism 2 to rotate to process the workpiece.
[0032] Specifically, the base 1 is located on the outside, and the base 1 is used to support and install various mechanisms. The tool mechanism 2 is located below the base 1, and the transmission mechanism 3 is located above the base 1. The tool mechanism 2 includes a spindle housing 21 installed on the transmission mechanism 3 and a spindle structure 22 installed on the spindle housing 21. The spindle structure 22 includes a tool mounting seat 221 rotatably connected to the spindle housing 21. The tool mounting seat 221 is vertically arranged and can rotate relative to the spindle housing 21. An axis core 222 is installed in the tool mounting seat 221. A tool claw 223 is installed at one end of the axis core 222. The tool claw 223 is located at the lower end of the axis core 222. The tool claw 223 is used to cooperate with the installation of the tool. By driving the tool mounting seat 221 to rotate, the tool claw 223 and the tool can be driven to rotate.
[0033] In this embodiment, the tool claw 223 is usually hidden in the tool mounting seat 221, and when it is needed, the tool claw 223 will extend from the tool mounting seat 221. To this end, the spindle structure 22 also includes a tool pushing structure 23 for pushing out the tool claw 223, and the tool pushing structure 23 includes a tool piston 231 arranged above the spindle structure 22 and a tool cylinder 232 for driving the tool piston 231, a tool spring is arranged between the tool piston 231 and the tool cylinder 232, and the tool piston 231 faces the shaft core 222; the shaft core 222 is provided with a pull rod 2221 for cooperating with the tool piston 231, and a disc spring is arranged between the shaft core 222 and the tool mounting seat 221.
[0034] When the tool claw 223 needs to be extended, the tool cylinder 232 drives the tool piston 231 to extend in the direction of the pull rod 2221 and pushes the pull rod 2221, and the pull rod 2221 drives the shaft core 222 to extend the tool claw 223. After the processing is completed, the tool cylinder 232 drives the tool piston 231 to return to its original position, and under the action of the disc spring, the shaft core 222 returns to the inside of the tool mounting seat 221.
[0035] In order to drive the spindle structure 22, the transmission mechanism 3 includes a transmission shaft 31 and a transmission gear structure 32 disposed on the transmission shaft 31, and the transmission gear structure 32 is connected to the tool mounting seat 221. The transmission shaft 31 is rotatably connected to the top of the base 1, and the transmission gear structure 32 includes a first bevel gear 321 disposed on the transmission shaft 31, a second bevel gear 322 meshing with the first bevel gear 321, a helical gear set 323 meshing with the second bevel gear 322, a third bevel gear 324 meshing with the helical gear set 323, and a fourth bevel gear 325 meshing with the third bevel gear 324, and the fourth bevel gear 325 is disposed on the tool mounting seat 221.
[0036] When the main shaft structure 22 needs to be driven, the transmission shaft 31 rotates and drives the first bevel tooth 321 to rotate through the rectangular spline. The rotating first bevel tooth 321 drives the second bevel tooth 322 to rotate. The second bevel tooth 322 drives the bevel gear set 323 to rotate. In this embodiment, the bevel gear set 323 includes three bevel gears meshing with each other. The rotating bevel gear set 323 drives the third bevel tooth 324 to rotate. The third bevel tooth 324 drives the fourth bevel tooth 325 to rotate. The fourth bevel tooth 325 transmits the torque to the tool mounting seat 221 through the rectangular spline. The tool mounting seat 221 can rotate quickly, thereby driving the shaft core 222 to rotate through the key connection.
[0037] Reference Figure 2 , Figure 3 and Figure 4 The A-axis indexing mechanism 4 includes an A-axis gear structure 41 disposed on the base 1, a indexing structure 42 for limiting the spindle housing 21, a shifting structure 43 for driving the A-axis gear structure 41 to operate, and an A-axis oil distributor 44. Specifically, the A-axis gear structure 41 includes an A-axis first indexing gear 411, an A-axis second indexing gear 412, and an A-axis third indexing gear 413 disposed on the base 1. The A-axis first indexing gear 411 is engaged or disengaged with the A-axis second indexing gear 412 under the drive of the shifting structure 43, and the A-axis second indexing gear 412 is engaged with the A-axis third indexing gear 413. The A-axis third indexing gear 413 is disposed on the spindle housing. The A-axis third indexing gear 413 can be mounted on the spindle housing by screw connection. The rotating A-axis third indexing gear 413 can drive the spindle housing 21 to swing and index.
[0038] Reference Figure 4 and Figure 7 The base 1 has an A-axis indexing support column 12 for mounting the A-axis first indexing gear 411, the A-axis first indexing gear 411 is rotatably connected to the A-axis indexing support column 12, the shifting structure 43 includes a shifting piston 431 and a shifting cylinder 432 arranged between the A-axis first indexing gear 411 and the A-axis indexing support column 12, a first oil chamber 121 and a second oil chamber 122 are provided between the A-axis indexing support column 12 and the shifting piston 431, and the first oil chamber 121 and the second oil chamber 122 are connected to the shifting cylinder 432.
[0039] The indexing structure 42 includes a movable toothed disc 421 screwed to the spindle housing 21, and a fixed toothed disc 211 meshing with the movable toothed disc 421 is fixedly mounted on the base 1. By driving the third indexing gear 413 of the A-axis to rotate, the spindle housing 21 can be driven to drive the movable toothed disc 421 to rotate, and the rotating movable toothed disc 421 rotates along the fixed toothed disc 211 for positioning. At the same time, the indexing structure 42 also includes a locking disc 422 for locking the fixed toothed disc 211 and the movable toothed disc 421, and the locking disc 422 is driven by the oil cylinder to abut or disengage with the fixed toothed disc 211 and the movable toothed disc 421. When A-axis indexing is required, the locking plate 422 is driven by the cylinder to move away from the fixed gear plate 211 and the movable gear plate 421 to release the limit on the spindle housing 21. When the indexing is completed, the locking plate 422 is driven by the cylinder to press against and engage with the fixed gear plate 211 and the movable gear plate 421 to limit the position of the spindle housing 21.
[0040] The working principle of the A-axis indexing mechanism 4 is as follows: the shift cylinder 432 supplies oil to the first oil chamber 121, and the shift piston 431 slides to drive the A-axis first indexing gear 411 to engage with the A-axis second indexing gear 412. After engagement, a signal is sent, and the locking plate 422 disengages the meshing movable gear plate 421 and the fixed gear plate 211 by releasing the pressure of the oil chamber to limit the contact of the spindle housing 21. Subsequently, the rotating A-axis first indexing gear 411 will drive the A-axis second indexing gear 412 to rotate, and the rotating A-axis second indexing gear 412 drives the A-axis third indexing gear 413 and the spindle housing to rotate. After the A-axis indexing is completed, the locking plate 422 presses against and engages with the fixed gear plate 211 and the movable gear plate 421 to limit the position of the spindle housing 21. It should be noted that the tool pusher structure 23 will also swing along with the indexing of the A-axis, thereby pushing out the tool claw 223 during processing, and the swing axis of the spindle housing 21 is the same as the axis of the third bevel tooth 324, so the swinging spindle housing 21 will not affect the normal operation of the tool mechanism 2 and the transmission mechanism 3.
[0041] By setting the A-axis gear structure 41 and the indexing structure 42, the three indexing gears of the A-axis gear structure 41 are used to drive the main shaft box to index, and the indexing structure 42 is used to cooperate and limit the main shaft box, and the main shaft box body 21 does not need to move during the entire indexing process. Compared with the structure of the prior art five-axis swing head that first separates the main shaft box body 21 as a whole from the base 1 by translation or swinging, and then uses the indexing gear to index, and finally combines with the base 1, the five-axis mechanical swing head of the present application can effectively reduce wear.
[0042] Reference Figure 5 In addition, in order to ensure the operating stability of the A-axis indexing mechanism 4, a self-lubricating sleeve 45 is rotatably connected to the outer side of the A-axis oil circuit distributor 44. By setting the self-lubricating sleeve 45, the wear of the A-axis oil circuit distributor 44 during long-term A-axis indexing operation can be reduced, thereby effectively extending the service life of the A-axis indexing mechanism 4.
[0043] Reference Figure 6 In order to cooperate with the installation of the C-axis indexing mechanism 5, the upper base 10 is above the base 1, and the upper base 10 is rotatably connected to the upper support seat 11. The upper support seat 11 can rotate relative to the upper base 10. The upper support seat 11, the upper base 10 and the transmission shaft 31 are each equipped with a pull pin 53 driven by a cylinder. The C-axis indexing mechanism 5 includes a C-axis indexing external gear 51 arranged on the transmission shaft 31 and a C-axis indexing internal gear 52 arranged on the inner side of the upper support seat 11. The C-axis indexing internal gear 52 is engaged or disengaged with the C-axis indexing external gear 51.
[0044] When performing C-axis indexing, the upper base 10 and the upper support seat 11 are driven to descend through the pull pin 53. The descending upper support seat 11 makes the C-axis indexing internal gear 52 engage with the C-axis indexing external gear 51. The transmission shaft 31 rotates to drive the upper support seat 11 to rotate relative to the upper base 1 for indexing. The rotating upper support seat 11 drives the overall transmission mechanism 3 and the tool mechanism 2 to rotate to a specified angle. After the indexing is completed, the cylinder drives the upper support seat 11 to rise through the pull pin 53, and the C-axis indexing internal gear 52 disengages from the C-axis indexing external gear 51, ending the C-axis indexing.
[0045] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0046] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
