Description

Technical Field

[0001] The utility model relates to the field of turrets, in particular to a high-load-bearing non-powered turret. Background Art

[0002] A non-powered turret actually refers to a non-powered servo hydraulic turret. The tool disc of a servo turret can only rotate by itself, but cannot rotate the tools on the tool disc alone. The structures of a non-powered turret and a powered turret are also very similar. A non-powered turret has a servo motor, which can be used to drive the active gear to rotate, thereby driving the driven gear fixed to the tool holder, and finally realizing the rotation of the tool disc and completing the position adjustment of each tool on the tool disc. In the actual process of rotating the tool disc, the driven gear, fixed gear, moving gear and piston in the turret are involved. The fixed gear is arranged in the inner hole of the driven gear. At the same time, the fixed gear The wheel and the moving gear are both sleeved on the outside of the piston, and a bushing matching the fixed gear is also provided on the outside of the piston. A first oil chamber can be formed between the piston and the moving gear, and a second oil chamber can be formed between the fixed gear and the bushing. When the first oil chamber is filled with oil, the moving gear and the fixed gear are meshed with each other under the push of oil pressure to limit the rotation of the moving gear. At this time, the moving gear is synchronously meshed with one side of the driven gear, thereby limiting the rotation of the driven gear, and ultimately ensuring the stability of the cutter disc after it rotates to the actual required position. When the second oil chamber is filled with oil, the moving gear is separated from the fixed gear, and the driven gear can rotate smoothly at this time, which is convenient for adjusting the position of the tool on the cutter disc.

[0003] To summarize, the piston is located at the central pressure-bearing position of the cutter disc. In addition to its own weight, the cutter disc also has the gravity of multiple tools evenly distributed in a circle. Therefore, the pressure that the cutter disc finally applies to the piston is extremely large. It is extremely difficult to withstand this pressure simply relying on the piston, which causes the piston to become eccentric, and eventually causes the axis of the cutter disc to shift. Once the cutter disc is eccentric, all the tools installed on the cutter disc will become eccentric, which ultimately makes it impossible to guarantee the accuracy of the tool when processing the workpiece, seriously affecting the processing quality.

[0004] The utility model aims to solve the existing technical problem by providing a high-load-bearing non-powered tool turret, which can achieve a high load-bearing effect, effectively avoid the eccentricity of the cutter disc, effectively ensure the coaxiality of the cutter disc, thereby achieving high precision during tool processing and effectively ensuring the processing quality.

[0036] The method of using the utility model is as follows:

[0037] The deep groove ball bearing 11 itself has a high load-bearing capacity and can effectively withstand radial loads and axial loads. Therefore, the deep groove ball bearing 11 can effectively improve the actual pressure-bearing capacity of the piston, effectively support the cutter disc 2, and effectively prevent the cutter disc 2 from being eccentric. The existence of the left rib 14 and the right rib 12 can firmly fix the deep groove ball bearing 11 on the left end of the piston 4, thereby ensuring that the deep groove ball bearing 11 is stably located between the piston 4 and the cutter disc 2, effectively ensuring the concentricity of the cutter disc 2. At the same time, the buffer sleeve 17 will be compressed and produce elasticity when the cutter disc 2 is eccentric. This elasticity can effectively counteract the pressure generated when the cutter disc 2 is eccentric, thereby effectively eliminating the pressure, further improving the pressure-bearing effect of the turret, thereby further preventing the cutter disc 2 from being eccentric, and ultimately ensuring the accuracy of the tool on the cutter disc 2 when processing the workpiece, so that the processing quality is effectively guaranteed.

[0038] When the second oil chamber 51 is filled with oil, the bushing 9 will move leftward and push the moving gear 5 to the left. At this time, the moving gear 5 is not engaged with the first meshing tooth 34 on the left side wall of the meshing portion 33 and the second meshing tooth 35 on the left side wall of the fixed gear 8. In this case, the driven gear 7 can rotate smoothly, and then the cutter disc 2 can be rotated. When the cutter disc 2 needs to be rotated, the motor 39 can be started. At this time, the motor shaft of the motor 39 will drive the active synchronous wheel 43 to rotate, and the active synchronous wheel 43 and the driven synchronous wheel 42 They are connected by a synchronous belt 44, so when the active synchronous wheel 43 rotates, the driven synchronous wheel 42 rotates synchronously with it, thereby realizing the rotation of the transmission shaft 41, and the active gear 45 arranged at the left end of the transmission shaft 41 is meshed with the driven gear 7. When the transmission shaft 41 drives the active gear 45 to rotate, the driven gear 7 rotates accordingly, and the driven gear 7 is fixed to the connecting part 16 on the right side of the cutter disc 2. When the driven gear 7 rotates, the cutter disc 2 rotates synchronously, thereby effectively realizing the position adjustment of each tool on the cutter disc 2.

[0039] When it is necessary to limit the rotation of the cutter disc 2, oil can be injected into the first oil chamber 49. Under the action of oil pressure, the guide rib 47 of the mobile gear 5 will move stably to the right along the outer circumference of the guide portion 46 of the piston 4, and finally the locking tooth 36 on the right side of the mobile gear 5 will mesh with the second meshing tooth 35 on the fixed gear 8, and the rotation of the mobile gear 5 will be effectively limited by the fixed gear 8. At the same time, the locking tooth 36 on the right side of the mobile gear 5 will mesh with the first meshing tooth 34 on the meshing portion 33, thereby limiting the mobile gear 5. When the mobile gear 5 is restricted from rotating, the cutter disc 2 is also restricted from rotating at the same time, thereby ensuring the stability after the tool position adjustment is completed.

[0040] The buffer structure includes a buffer sleeve 17 arranged in the positioning groove 15, the buffer sleeve 17 is sleeved on the outside of the connecting portion 16, and an annular elastic groove 18 is provided on the left end face of the buffer sleeve 17. A support portion 19 extends inward from the inner wall of the left end hole of the inner hole of the buffer sleeve 17, and the inner wall of the support portion 19 fits with the outer wall of the connecting portion 16, and the outer wall of the buffer sleeve 17 fits with the inner circumferential surface of the positioning groove 15. When the cutter disc 2 is eccentric, the connecting portion 16 will be eccentric synchronously. At this time, the inner wall of the support portion 19 will be squeezed outward by the connecting portion 16, and the existence of the elastic groove 18 can make the buffer sleeve 17 generate elasticity when being squeezed, thereby effectively resisting and eliminating pressure, and the thickness of the support portion 19 gradually decreases toward the axial direction of the connecting portion 16, thereby effectively reducing the friction area between the inner wall of the support portion 19 and the outer wall of the connecting portion 16, effectively reducing the resistance encountered by the cutter disc 2 during rotation, and effectively ensuring the smoothness of the cutter disc 2 during rotation.

[0041] The left side wall of the turret frame 1 is provided with an annular supporting rib 20, which is coaxial with the rotating groove 6. The outer wall of the cutter disc 2 is provided with an annular positioning portion 21, and the outer wall of the positioning portion 21 is in contact with the inner wall of the supporting rib 20. The supporting rib 20 can form a new support, and can effectively support the cutter disc 2 through the positioning portion 21, further ensuring the coaxiality of the cutter disc 2 and further avoiding the eccentricity of the cutter disc 2.

[0042] The right end face of the piston 4 is provided with a plurality of positioning screw holes 52 which are evenly distributed around the circumference, and the left wall of the mounting cavity 37 is provided with a plurality of through holes 53 which are connected with the positioning screw holes 52. The stability of the piston 4 can be achieved by passing the screws through the through holes 53 and being screwed into the positioning screw holes 52, and at the same time pressing the heads of the screws against the left wall of the mounting cavity 37, and at the same time effectively ensuring that the axis of the piston 4 is not deviated.

This fixing method is conducive to the disassembly and assembly between the driven gear 7 and the cutter disc 2.

[0044] The left end face of the piston 4 is provided with a plurality of second screw holes 24 evenly distributed in a circle, and the left side wall of the limiting member 13 is provided with a plurality of second countersunk holes 25 intersecting the second screw holes 24. The piston 4 and the limiting member 13 can be fixed by only passing the screws through the second countersunk holes 25 and being screwed into the second screw holes 24. This fixing method is conducive to the disassembly and assembly between the piston 4 and the limiting member 13.

[0045] An annular dustproof groove 26 is provided on the inner wall of the left end of the load-bearing hole 10, and a dustproof plate 27 matching it is provided in the dustproof groove 26. The dustproof plate 27 covers and seals the left end of the load-bearing hole 10. A plurality of third screw holes 28 evenly distributed in a circle are provided on the right side wall of the dustproof groove 26, and a plurality of third countersunk holes 29 intersecting the third screw holes 28 are provided on the left side wall of the dustproof plate 27. The dustproof plate 27 can be fixed by simply passing the screws through the third countersunk holes 29 and screwing them into the third screw holes 28. This fixing method is conducive to the disassembly and assembly of the dustproof plate 27, and the existence of the dustproof plate 27 can effectively prevent external dust or impurities from entering the deep groove ball bearing 11, thereby effectively achieving a dustproof effect.

[0046] An annular groove 30 is provided on the right side wall of the left retaining edge 14, and an annular embedding hole 31 is provided at the bottom of the groove 30. An auxiliary part 32 matching therewith is provided in the embedding hole 31. The auxiliary part 32 is in the shape of a trumpet with a narrow left side and a wide right side. The right end of the auxiliary part 32 penetrates into the groove 30 to the right and presses against the left side wall of the deep groove ball bearing 11. The auxiliary part 32 is made of rubber. When the cutter disc 2 is eccentric, the deep groove ball bearing 11 will be squeezed at the same time to make it synchronously eccentric. When the deep groove ball bearing 11 is eccentric, the right end of the auxiliary part 32 will be driven to deform the auxiliary part 32 and generate elasticity. This elasticity can effectively resist the pressure generated by the eccentricity and eliminate this pressure, thereby further ensuring the coaxiality of the cutter disc 2.

[0047] The right side wall of the fixed gear 8 is provided with a plurality of evenly distributed fourth screw holes 54, and the left side wall of the mounting cavity 37 is provided with a plurality of through holes 55 intersecting the fourth screw holes 54.
