[0002] Sleeve parts are a common workpiece. According to different uses, the outer wall of some sleeve parts has multiple holes along the radial direction of the sleeve parts. After turning the main body of the sleeve parts, it needs to be drilled Drilling usually uses a chuck to fix the sleeve parts and then turns the hole. However, no matter whether internal fixation or external fixation is adopted, the contact range between the chuck and the sleeve parts is limited. The impact force will cause the deformation of the sleeve parts. For the sleeve parts with high precision requirements, the sleeve parts need to be corrected after drilling, which leads to low manufacturing efficiency and high cost.
[0003] Chinese patent CN202010512662.2 discloses a drilling machine positioning fixture for sleeve parts, mainly related to the technical field of machine tool fixtures; including a support plate, one side of the support plate is centered on the center of the side of the support plate, and the annular array is equipped with A plurality of chute, each of which is provided with a first slider and a second slider, the middle part of the side of the first slider away from the support plate is horizontally provided with an inner support plate, the inner The middle part of the support plate is provided with a waist-shaped hole along the length direction of the inner support plate, and a lead screw is provided in each of the chute, and a nut suitable for the lead screw is inlaid on the first slider. The middle part of the support plate is horizontally equipped with a rotating shaft and a hollow shaft; this device only relies on the inner support plate to locate and fix sleeve parts, which is prone to breakage during drilling

Embodiment 1
[0040] refer to figure 2 As shown, an automatic drilling equipment for machining radial holes of sleeve parts, including:
[0041] The duplex sliding assembly 1, the duplex working ends of which can move towards each other or back;
[0042] The first rotating assembly 2 and the second rotating assembly 3, the working ends of the rotating assemblies are coaxial and oppositely arranged at the double working ends of the duplex sliding assembly 1;
[0043] The three-claw elastic positioning component 4 is coaxially arranged at the working end of the rotating component, and the working end of the three-claw elastic positioning component 4 can elastically slide along its radial direction;
[0044] The adjustable expansion claws 5 are evenly distributed on the working end of the three-claw elastic positioning assembly 4 along the axis, and the adjustable expansion claws 5 include an expansion rod 5a that can move in the radial direction so as to abut against the inner circumference...
Embodiment 2
[0084] Compared with embodiment 1, in this embodiment, if Figure 9 As shown, the abutting piece 5b is also provided with a second sliding groove 5b3 along the radial direction of the sleeve parts; the abutting piece 5b also includes:
[0085] The second threaded rod 5b4 is arranged in the second sliding groove 5b3 along the radial rotation of the sleeve parts;
[0086] The second internally threaded sliding block 5b5 is slidably arranged in the second chute 5b3 along the radial direction of the sleeve parts and screwed coaxially with the second threaded rod 5b4. On the internal thread sliding block 5b5;
[0087] The adjusting nut 5b6 and the drill sleeve 5b2 are coaxially screwed and fixedly arranged on the installation rod 5b1 through the adjusting nut 5b6.
[0088] Because the second threaded rod 5b4 is screwed coaxially with the second internally threaded sliding block 5b5, by turning the second threaded rod 5b4, the second internally threaded sliding block 5b5 can drive...
