[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-7 As shown, a sleeve tooling fixture includes a worktable 10, on which a four-axis rotary table 21 and a tailstock 22 are mounted. A drive shaft is driven onto the four-axis rotary table 21. The four-axis rotary table 21 is existing technology and will not be described in detail here. A fixing bracket 20 is fixedly mounted on the drive shaft. A connecting shaft is mounted at the other end of the fixing bracket 20. The connecting shaft is coaxial with the drive shaft and rotatably mounted within the tailstock 22. The tailstock 22 is a bearing housing. The fixing bracket 20 is equipped with... The sleeve 1 is equipped with a positioning seat 5, a first positioning component 3, and a second positioning component 4. In this application, there are two positioning seats 5. The positioning seat 5 is provided with a positioning groove 51 that is adapted to the cylinder 11 and a limiting block 52 that abuts against the end of the connecting plate 12. The limiting block 52 is located at the front end of the positioning seat 5. The first positioning component 3 cooperates with the positioning seat 5 to realize the positioning of the sleeve 1 in the x-axis and z-axis directions. The second positioning component 4 cooperates with the limiting block 52 to realize the positioning of the sleeve 1 in the y-axis direction.

[0024] The fixing frame 20 is also equipped with a support component 6, which is used to abut against the bottom of the connecting plate 12. The support component 6 cooperates with the first positioning component 3 to keep the axis of the sleeve 1 horizontal with the upper surface of the fixing frame 20.

[0025] The fixing frame 20 includes a fixing plate 24 and two connecting frames 23. Each connecting frame 23 includes a mounting plate 231 and a shelf 232. The mounting plate 231 and the shelf 232 are integrally formed and are L-shaped. The fixing plate 24 is installed on the upper end of the two shelf 232. The positioning seat 5, the first positioning component 3, the second positioning component 4, and the support component 6 are all installed on the fixing plate 24. The drive shaft and the connecting shaft are respectively installed on the two mounting plates 231 at opposite ends.

[0026] The first positioning component 3 includes a fixed base 31, two first rotary cylinders 32 and two first rotary arms 33. The drive shaft of the first rotary cylinder 32 is arranged along the height direction of the worktable 10. The fixed base 31 is fixedly installed on the fixed frame 20. The first rotary cylinders 32 are all installed in the fixed base 31. The two first rotary arms 33 are respectively driven and installed on the two first rotary cylinders 32.

[0027] When the first rotating arm 33 is in the initial state, the first rotating arm 33 extends along the y-axis direction. When the first rotating arm 33 is in the working state, the first rotating arm 33 rotates to extend along the x-axis direction.

[0028] Each end of the first rotating arm 33 is hinged with an abutment block 34. Each abutment block 34 is provided with a mating groove 341 that is adapted to the cylinder 11. The mating groove 341 and the positioning groove 51 cooperate with each other to restrict the movement of the sleeve 1 in the x-axis and z-axis directions, that is, to achieve the clamping function.

[0029] Preferably, the mating groove 341 and the positioning groove 51 are trapezoidal in shape, thus enabling them to accommodate more sleeves 1 of different sizes.

[0030] The second positioning component 4 includes a mounting base 41, a second rotary cylinder 42, and a second rotary arm 43. The drive shaft of the second rotary cylinder 42 is arranged along the width direction of the worktable 10. The mounting base 41 is fixedly mounted on the fixed frame 20. The second rotary cylinder 42 is installed inside the mounting base 41. The second rotary arm 43 is driven to be mounted on the second rotary cylinder 42.

[0031] When the second rotating arm 43 is in the initial state, the second rotating arm 43 extends along the z-axis direction. When the second rotating arm 43 is in the working state, the second rotating arm 43 rotates to extend along the x-axis direction.

[0032] The second rotating arm 43 is hinged to a connecting block 44 at its end. The connecting block 44 is provided with two adjusting bolts 45. The adjusting bolts 45 are used to abut against the front end of the connecting plate 12. The distance from the end of the adjusting bolt 45 to the connecting plate 12 is adjusted by the threaded engagement between the adjusting bolt 45 and the connecting block 44, thereby adjusting the abutment engagement between the bolt 45 and the connecting plate 12, thereby restricting the movement of the sleeve 1 in the y-axis direction.

[0033] It should be noted that the first rotating cylinder 32 and the second rotating cylinder 42 will move axially while rotating, thus ensuring that the abutting block 34 and the connecting block 44 can abut against the sleeve 1.

[0034] The support assembly 6 includes a cylinder 61, a movable block 62, and a pressure block 63. The cylinder 61 is fixedly mounted on the fixed frame 20. The movable block 62 is fixedly mounted on the output end of the cylinder 61. The pressure block 63 is mounted on the upper end of the movable block 62. The upper end of the pressure block 63 is provided with two contact blocks 64. The upper surface of the contact blocks 64 is parallel to the upper surface of the workbench 10. Therefore, when the contact blocks 64 contact the bottom of the connecting plate 12, they can level the connecting plate 12.

[0035] In practical use: By placing the cylinder 11 of the sleeve 1 into the positioning groove 51 of the positioning seat 5, firstly, the cylinder 61 is activated, which drives the movable block 62 to move upward, thereby driving the pressure block 63 to move upward, so that the contact on the pressure block 63 abuts against the bottom of the connecting plate 12 on the sleeve 1. The two contact blocks 64 abut against the connecting plate 12, thereby leveling the connecting plate 12. Further, the second rotation is activated, which drives the second rotating arm 43 to rotate to the working state, so that the adjusting bolt 45 on the connecting block 44 abuts against the front end of the connecting plate 12. The adjusting bolt 45 and the limiting block 52 clamp the connecting plate 12, thereby restricting the movement of the sleeve 1 in the y-axis direction. Further, the two first rotating cylinders 32 are activated, which drives the two first rotating arms 33 to rotate to the working state, so that the abutting block 34 abuts against the cylinder 11 of the sleeve 1, and the cylinder 1 When the sleeve 11 abuts against the abutting block 34, the sleeve 11 is located in the mating groove 341. Since the positioning groove 51 and the mating groove 341 are trapezoidal, when the sleeve 11 abuts against the mating groove 341 and the positioning groove 51, the movement of the sleeve 1 in the x-axis and z-axis directions can be restricted, thus achieving clamping of the sleeve 1. After clamping is completed, the second rotary cylinder 42 and the cylinder 61 are closed. When the cylinder 61 is closed, the movable block 62 and the pressure block 63 are driven to move in the opposite direction, thereby causing the contact block 64 to disengage from the bottom of the connecting plate 12. When the second rotary cylinder 42 is closed, the second rotary arm 43 rotates in the opposite direction, thereby causing the adjusting bolt 45 to disengage from the connecting plate 12, so that the front end face of the connecting plate 12 and the outer peripheral wall of the connecting plate 12 of the sleeve 1 can be drilled or milled. The fixed frame 20 is driven to rotate by the four-sided turntable, thereby achieving the processing of multiple surfaces of the sleeve 1.
