[0002] A drilling machine is a machine tool that mainly uses a drill to make holes on a workpiece. Usually, the rotation of the drill is the main motion, and the axial movement of the drill is the feed motion. The drilling machine has a simple structure and relatively low processing accuracy. It can drill through holes and blind holes. By replacing special tools, it can expand, countersink, ream holes or perform tapping and other processing. During the processing, the workpiece does not move, the tool moves, aligns the center of the tool with the center of the hole, and rotates the tool (main motion). The characteristic of a drilling machine is that the workpiece is fixed and the tool rotates.

The driving member 334 can be installed on the ground or on the side of the equipment by screws, so that the application range of the present device is wider, and there is no need to limit the installation position of the present device due to the installation position of the driving member 334. The length of the synchronous belt 332 can be adjusted according to the position distance of the first transmission wheel 331 and the second transmission wheel 333 to ensure the stability of the first transmission wheel 331 and the second transmission wheel 333 when they rotate synchronously.

[0034] As an optional solution of the present invention, the worm 32 is located at the outer end of the base 1 and is sleeved with a limiting sleeve 5, the limiting sleeve 5 is fixedly connected to the base 1, the limiting sleeve 5 and the base 1 are integrally formed, and the axis of the limiting sleeve 5 is provided with a channel for the worm 32 to pass through, and the section of the worm 32 passing through the limiting sleeve 5 is a smooth cylindrical surface; when the worm 32 rotates, the limiting sleeve 5 can prevent eccentric movement when the speed of the worm 32 is fast or the torque is large, thereby ensuring stable meshing rotation between the worm 32 and the worm wheel 31, and then ensuring the speed stability when the driving disk 2 rotates horizontally, so that the milled structure quality is better, and at the same time helps to extend the service life of the milling cutter.

When the clamping member 41 is locked by the second locking nut 94, the block 93 will contact the end surface of the clamping member 41 under the action of the locking force of the second locking nut 94, thereby more evenly applying the locking force generated by the second locking nut 94 to the clamping member 41, thereby ensuring the stability of the clamping member 41 when it is locked.

[0037] In this embodiment, in order to clamp a cylindrical workpiece (such as a steel-lined polytetrafluoroethylene tube), a V-shaped opening is provided on the side of the clamping member 41 that contacts the workpiece. The V-shaped opening can accommodate objects of different diameters. The clamping groove 411 is also a V-shaped structure in this embodiment. Because a flange is generally provided at the end of the steel-lined polytetrafluoroethylene tube, the V-shaped clamping groove 411 can be used to fix the flange, thereby making the fixation of the workpiece more secure.

[0038] As an optional solution of the present invention, a clamping portion 412 is installed above at least one of the clamping members 41, the clamping portion 412 is attached to the upper end surface of the clamping member 41 and can move back and forth on the clamping member 41 relative to the clamping direction of the workpiece, a clamping groove 411 is formed between the clamping portion 412 and the clamping member 41, the clamping groove 411 is a gap between the clamping portion 412 and the clamping member 41, and the side of the clamping portion 412 in contact with the workpiece is a V-shaped opening, and the clamping member 41 is provided with an adjustment for driving the clamping portion 412 to move back and forth on the clamping member 41. Section structure 10; when fixing a workpiece with a flange, the operator can place the flange of the workpiece on the clamping groove 411, and then drive the clamping part 412 toward the workpiece by adjusting the structure 10 so that the flange of the workpiece is clamped. By clamping the flange of the workpiece instead of the workpiece itself, it helps to improve the stability of the workpiece when clamping. At the same time, after the weight of the workpiece acts on the clamping part 41, it is easier to control the movement of the clamping part 412 than to control the movement of the clamping part 41. For the operator, it is easier to fix the workpiece with a flange and the fixing effect is better.

[0039] In this embodiment, in order to further improve the stability during clamping, only one side of the clamping member 41 is equipped with a clamping portion 412 .

The clamping member 41 is provided with a movable groove 413 for the adjustment part 101 to move back and forth. When using the adjustment structure 10, the operator controls the adjustment from the outside. The screw 102 rotates. Since the adjusting screw 102 is threadedly connected to the clamping member 41, the adjusting screw 102 will be displaced when it rotates. Since one end of the adjusting screw 102 is rotatably connected to the adjusting portion 101, the adjusting portion 101 will move left and right with the adjusting screw 102, thereby achieving the purpose of the adjusting screw 102 controlling the clamping portion 412 to move left and right. When the operator does not rotate the adjusting screw 102, the position of the clamping portion 412 remains fixed, and the workpiece can be clamped stably.

[0042] The present invention and its embodiments are described schematically above, and the description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto.
