[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] This application provides a drilling machine for machining crankshaft oil passage holes, which solves the problems of inconvenient operation when positioning workpieces in current drilling machines. The tooling generally uses a clamping plate to hold and limit the workpiece. Due to the special nature of the crankshaft, this clamping method is prone to shaking during operation, making positioning inconvenient. In order to ensure the accuracy of drilling, the positioning time is long. At the same time, the unstable clamping may cause movement during the machining process, affecting the drilling accuracy and reducing the machining quality.

[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0034] Example 1: This utility model embodiment discloses a drilling machine for machining crankshaft oil passage holes, according to the attached... Figure 1-5 As shown, it includes a base 1, a limiting seat 2, a drilling unit 3, and a positioning unit 4;

[0035] Base 1 is the supporting foundation for the entire drilling machine;

[0036] The limiting seat 2 is mounted on the base 1 and is equipped with a locking block 21 for locking the workpiece. This design can initially fix and limit the workpiece, so that the workpiece will not shift during placement and processing.

[0037] The drilling unit 3 is also mounted on the base 1 and is used to perform actual drilling operations on the workpiece. The drilling unit 3 includes a support platform 31, an electric push rod 32, and a drill 33.

[0038] The support platform 31 serves to support and fix the electric push rod 32, which in turn drives the drilling rig 33 to move up and down, thereby realizing the feed and retraction actions of the drill. In addition, a slider 331 is slidably connected to the support platform 31, and the drilling rig 33 is fixedly connected to the slider 331. This facilitates lateral support for the position of the drilling rig 33, ensures the stability of the drilling rig 33 under force, and improves drilling accuracy.

[0039] The positioning unit 4 ensures that the workpiece is accurately positioned on the limit seat 2. The positioning unit 4 includes a guide rail seat 41, an adjustment table 42, a lead screw 43, and a lifting seat 44.

[0040] The guide rail seat 41 is fixed on the base 1, providing a guide rail for the sliding of the adjustment table 42. The adjustment table 42 is slidably connected to the guide rail seat 41 and threadedly connected to the lead screw 43. The lead screw 43 is rotatably connected to the guide rail seat 41. By rotating the rotation handle 431 of the lead screw 43, the position of the adjustment table 42 on the guide rail seat 41 can be precisely controlled, thereby realizing the lateral positioning adjustment of the workpiece.

[0041] The lifting seat 44 is mounted on the adjusting table 42, and a clamping block 441 for clamping the workpiece is provided on it. A reinforcing rib 443 is provided between the lifting seat 44 and the adjusting table 42. The lifting seat 44 and the adjusting table 42 are fixedly connected by the reinforcing rib 443 to enhance the stability of the structure.

[0042] Meanwhile, the lifting seat 44 is also provided with a coolant guide groove 442, which facilitates the introduction and discharge of coolant, cools and lubricates the drilling process, and improves the processing quality and tool life.

[0043] The clamping block 441 is fixed to the lifting seat 44 by bolts. This connection method facilitates the disassembly and replacement of the clamping block 441 to adapt to the clamping requirements of workpieces of different shapes and sizes, and also facilitates the maintenance and adjustment of the clamping block 441.

[0044] The drilling machine used for machining crankshaft oil passage holes achieves initial positioning of the workpiece through the limit seat 2 and the chuck 21, and then uses the positioning unit 4 for precise positioning. Combined with the drilling operation of the drilling unit 3, it realizes high-precision positioning drilling of the workpiece, effectively prevents the workpiece from shifting during the machining process, significantly improves the machining accuracy of the oil passage holes, and ensures that the quality of the crankshaft meets strict standards.
