DETAILED DESCRIPTION

[0028] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0029] Embodiment 1

[0030] like Figures 1 to 10As shown, a multi-directional locking tool for high-precision machining of saddles comprises an annular tool seat 1, the inner wall of the annular tool seat 1 is provided with a first plane positioning groove 2 and a second plane positioning groove 3, the first plane positioning groove 2 is perpendicular to the second plane positioning groove 3, a first wear-resistant block 4 and a second wear-resistant block 5 are respectively arranged in the first plane positioning groove 2 and the second plane positioning groove 3, the annular tool seat 1 is provided with a plurality of tool extrusion mechanisms between the first plane positioning groove 2 and the second plane positioning groove 3, the plurality of tool extrusion mechanisms are evenly distributed along the circumferential direction of the annular tool seat 1, and the tool extrusion mechanisms include a main slide The inner wall of the annular tooling seat 1 is provided with a guide slot 8 at the position where the tooling extrusion mechanism is set. The guide slot 8 is set along the axial direction of the annular tooling seat 1. The main slider 6 is slidably adapted in the guide slot 8. An adjustment block 7 is set at one end of the main slider 6 close to the center of the annular tooling seat 1. One end of the adjustment block 7 is slidably penetrated in the main slider 6. A pressure sensor 9 is embedded at one end of the adjustment block 7 away from the main slider 6. The main slider 6 and the adjustment block 7 have the freedom to move radially along the annular tooling seat 1, and the main sliders 6 in multiple tooling extrusion mechanisms move synchronously. The saddle is placed on the inner ring of the annular fixture seat 1, and the saddle is supported by the annular boss arranged on the inner ring of the annular fixture seat 1, and the surface 1 and surface 2 of the saddle are respectively contacted with the first wear-resistant block 4 and the second wear-resistant block 5 to complete the radial positioning of the saddle, and multiple fixture extrusion mechanisms are started to clamp the saddle, and the main sliders 6 in the multiple fixture extrusion mechanisms are synchronously moved close to the saddle, so that the main slider 6 drives the adjustment block 7 to contact the outer ring of the saddle to complete the initial clamping, and the initial clamping of the saddle is performed by synchronously driving the main slider 6, so as to improve the tooling efficiency of the saddle, and the pressure of the pressure sensor 9 The shaft will contact the outer ring of the saddle, and the pressure signal transmitted by the pressure sensor 9 will be used to determine whether the adjustment block 7 is in place. If the pressure value of the pressure sensor 9 is lower than the preset value, the corresponding adjustment block 7 will be adjusted to make the adjustment block 7 continue to move closer to the outer ring of the saddle until the pressure signal of the pressure sensor 9 reaches the preset value. This will adapt to the processing error of the outer ring of the saddle, enable each tooling extrusion mechanism to be well pressed against the saddle, achieve high-precision tooling, and have high tooling strength, ensuring that the saddle will not deviate under the vibration of grinding, thereby indirectly achieving high-precision processing of the saddle.

[0031] Embodiment 2

[0032] Based on the first embodiment, Figure 1 , Figure 5 , Figure 8 and Fig. 9As shown, an axial positioning mechanism is provided at the top of the annular fixture seat 1, and the axial positioning mechanism includes a positioning beam 43 and an end face extrusion block 44. The two ends of the positioning beam 43 are connected to the annular fixture seat 1 by positioning bolts 45. The end face extrusion block 44 is arranged below the positioning beam 43. The end face extrusion block 44 has the freedom to move axially along the annular fixture seat 1. The positioning beam 43 is threadedly connected with an extrusion bolt 46. The tail of the extrusion bolt 46 passes through the positioning beam 43 and is rotatably connected to the end face extrusion block 44. A guide slide bar 47 is fixed to the bottom of the positioning beam 43. The guide slide bar 47 is slidably penetrated in the end face extrusion block 44. After the radial positioning of the saddle is completed, the axial movement of the saddle is performed. After positioning, the saddle is clamped by the tooling extrusion mechanism, the positioning crossbeam 43 is installed on the annular tooling seat 1 by the positioning bolt 45, and then the extrusion bolt 46 is screwed downward, and the rotational freedom of the end face extrusion block 44 is limited by the guide slide bar 47. Since the extrusion bolt 46 rotates to connect the end face extrusion block 44, the screwing movement of the extrusion bolt 46 is converted into the freedom of the end face extrusion block 44 to move axially along the saddle, so that the end face extrusion block 44 squeezes the axial surface of the saddle to complete the axial positioning of the saddle, so that the saddle is first positioned axially and radially, and finally the clamping tool is performed, and the clamping strength is high, which can keep it from deviating under the vibration of grinding.

[0033] Embodiment 3

[0034] Based on the second embodiment, Figure 1 , Figure 8 and Fig. 9 As shown, the end face extrusion block 44 includes a first extrusion block 48 and a second extrusion block 49. The first extrusion block 48 and the second extrusion block 49 are connected to form a T shape. The first extrusion block 48 is located between the second extrusion block 49 and the positioning beam 43. Balls 50 are rotatably installed at both ends of the bottom of the first extrusion block 48. The second extrusion block 49 penetrates the inner ring of the saddle. The length of the first extrusion block 48 is greater than the diameter of the inner ring of the saddle, so that the second extrusion block 49 drives the ball 50 to extrude the saddle to complete the axial positioning of the saddle. Considering that the saddle will be fine-tuned to complete the positioning during the axial positioning, the ball 50 is arranged to contact the saddle for positioning, and the radial movement of the saddle is not restricted, which facilitates the fine-tuning of the saddle for axial positioning.

[0035] Embodiment 4

[0036] Based on the third embodiment, Figures 1 to 4As shown, the tooling extrusion mechanism also includes a driving shaft 10 and a screw 11. An annular cavity 12 is provided in the annular tooling seat 1. The guide groove 8 is located in the inner ring of the annular cavity 12. The screw 11 is rotatably connected to the annular tooling seat 1. A threaded hole 13 is opened at one end of the main slider 6 away from the adjustment block 7. One end of the screw 11 is threadedly adapted in the threaded hole 13. The other end of the screw 11 extends into the annular cavity 12 and is connected to the first bevel gear 14. The driving shaft 10 is rotatably arranged in the annular cavity 12. The axis of the driving shaft 10 is parallel to the annular tooling seat 1. The axis of the mounting seat 1, the driving shaft 10 is perpendicular to the screw 11, the driving shaft 10 is provided with a second bevel gear 15, the second bevel gear 15 meshes with the first bevel gear 14, an annular shaft 16 is provided in the annular cavity 12 for rotation, the annular shaft 16 is coaxial with the annular fixture seat 1, an inner ring gear 17 is installed on the inner ring of the annular shaft 16, a driven gear 18 is provided on the driving shaft 10, the driven gear 18 meshes with the inner ring gear 17, a worm wheel 19 is provided on the annular shaft 16, the worm wheel 19 meshes with a worm 20, and the worm 20 is rotatably connected to the annular fixture seat The seat 1 has one end of the worm 20 extending out of the annular tooling seat 1 and fixed with a rotating nut 21. The worm 20 is rotated by acting on the rotating nut 21 with a wrench. The annular shaft 16 is driven to rotate by the meshing of the worm 20 and the worm wheel 19. The annular shaft 16 drives the inner gear ring 17 to rotate. The inner gear ring 17 drives the driving shaft 10 to rotate through the driven gear 18. The driving shaft 10 drives the screw 11 to rotate by the meshing of the first bevel gear 14 and the second bevel gear 15. The sliding cooperation between the main slider 6 and the guide slot 8 limits the rotation of the main slider 6. The main slider 6 has a large degree of freedom, which makes the main slider 6 move in a straight line along the axial direction of the screw rod 11, so that the main slider 6 drives the adjustment block 7 to move radially along the annular tooling seat 1, thereby realizing the clamping tooling of the saddle. Through this driving method, the main sliders 6 of multiple tooling extrusion mechanisms can be moved synchronously to complete the rapid preliminary clamping of the saddle, and then the individual adjustment blocks 7 that are not tightly abutted can be adjusted, thereby improving the tooling efficiency of the saddle; the self-locking effect of the worm wheel 19 and the worm 20 is used to complete the position locking of the main slider 6, thereby improving the tooling strength.

[0037] Embodiment 5

[0038] Based on the fourth embodiment, Figures 1 to 4As shown, the main slider 6 is provided with an adjustment installation groove 22 at one end where the adjustment block 7 is set, and an adjustment screw 23 is rotatably set in the adjustment installation groove 22. One end of the adjustment block 7 is slidably adapted in the adjustment installation groove 22, and an adjustment threaded hole 24 is provided at one end of the adjustment block 7 close to the adjustment screw 23. One end of the adjustment screw 23 is threadedly fitted in the adjustment threaded hole 24. An adjustment worm gear 25 is sleeved on the adjustment screw 23, and an adjustment worm 26 is meshed with the adjustment worm gear 25. One end of the adjustment worm 26 is rotatably connected to the main slider 6, and the axis of the adjustment worm 26 is parallel to the axis of the annular fixture seat 1. The adjusting worm 26 drives the adjusting screw 23 to rotate by meshing with the adjusting worm wheel 25. Since the adjusting block 7 slides and fits into the adjusting mounting groove 22, the rotational freedom of the adjusting block 7 is limited, so that the adjusting block 7 moves linearly along the axial direction of the adjusting screw 23, so that the adjusting block 7 can continue to move for position adjustment after the position of the main slider 6 is locked, so that the adjusting block 7 can contact the outer ring of the saddle under a preset pressing force, so that each tooling extrusion mechanism can press the saddle with a set force to adapt to the machining accuracy error of the outer ring of the saddle, thereby greatly improving the tooling strength of the saddle.

[0039] Embodiment 6

[0040] Although the worm wheel 19 cannot reverse to drive the worm 20 to rotate, and the adjustment worm wheel 25 cannot reverse to drive the adjustment worm 26 to rotate, the worm 20 and the adjustment worm 26 are easily reversed by external influences, causing the tooling to loosen. Therefore, based on the fifth embodiment, as Figures 1 to 6As shown, a limiting circular groove 27 is provided on the top of the main slider 6, and a plurality of tooth grooves are evenly distributed on the inner wall of the limiting circular groove 27 along its own circumferential direction. A rectangular groove 28 is provided on the top of the adjusting worm 26 along its own axial direction. A sliding drive rod 29 is slidably adapted in the rectangular groove 28, and a limiting spring 32 is arranged in the rectangular groove 28. The two ends of the limiting spring 32 are respectively connected to the sliding drive rod 29 and the adjusting worm 26. One end of the sliding drive rod 29 extends into the limiting circular groove 27 and is connected to the limiting column 30. The side wall of the limiting column 30 is evenly fixed with a plurality of limiting teeth 31 along its own circumferential direction. When the limiting spring 32 is in a normal state, the limiting teeth 31 are adapted in the tooth grooves. A locking screw 33 is threadedly connected to the outer wall of the annular tooling seat 1, and the locking screw 33 is pressed against the worm 20. When the position of the main slider 6 is moved into place, the locking screw 3 is tightened. The rear end of the locking screw 33 is pressed against the worm 20 to limit its rotation, thereby preventing the worm 20 from reversing and causing the main slider 6 to move back. When adjusting the adjustment block 7, the limit column 30 is pulled up to make the limit tooth 31 on the limit column 30 disengage from the tooth groove, so that the sliding drive rod 29 can be driven to rotate by rotating the limit column 30, and the sliding drive rod 29 and the adjustment worm 26 have a linear movement freedom, which can be achieved by means of a slide bar and a slide groove, so that the sliding drive rod 29 can drive the adjustment worm 26 to rotate, and the position adjustment of the adjustment block 7 is completed. When the adjustment is completed, the limit column 30 is inserted into the limit circular groove 27, so that the limit tooth 31 cooperates with the tooth groove, thereby limiting the rotational freedom of the adjustment worm 26, and the limit tooth 31 will not be disengaged from the tooth groove through the force of the limit spring 32, thereby effectively preventing the clamping from loosening.

[0041] Embodiment 7

The coaxial limit block 34 is installed above the pressure sensor 9, and a limit slot 35 is provided at one end of the adjustment block 7 away from the main slider 6. A coaxial limit spring 36 is arranged in the limit slot 35, and one end of the coaxial limit block 34 slides into the limit slot 35 and is connected to the coaxial limit spring 36. A wedge surface 37 is provided on the top surface of the coaxial limit block 34 connected to one end of the coaxial limit spring 36, and an extrusion wedge surface 51 is provided on the bottom surface of the coaxial limit block 34 away from one end of the coaxial limit spring 36.

Before the tooling saddle is installed, the coaxial limit block 34 is completely located in the limit slot 35 under the action of the coaxial limit spring 36. When the saddle completes the clamping tooling through the tooling extrusion mechanism, the downward pressing screw 38 is tightened, and the downward pressing screw 38 drives the downward pressing hemisphere 39 to squeeze the wedge surface 37 of the coaxial limit block 24. Under the action of the wedge surface 37, the coaxial limit block 24 stretches the coaxial limit spring 36 to move, so that the coaxial limit block 24 extends out of the limit slot 35 to squeeze the top surface of the saddle. Under the action of squeezing the wedge surface 51, it can adapt to the processing error of the top surface of the saddle. The axial positioning tooling of the saddle is completed by squeezing the wedge surface 51 to press the saddle downward, thereby realizing the axial and radial positioning tooling of the saddle, and the tooling has high precision and high strength.
