Abstract

Technical Field
[0001] This utility model belongs to the field of numerical control technology, specifically relating to a motion trajectory recording device based on a three-dimensional numerical control slide table. Background Technology
[0002] CNC machine tools, short for numerical control machine tools, are automated machine tools equipped with a program control system. This control system logically processes programs with control codes or other symbolic instructions, decodes them, represents them with coded numbers, and inputs them into the CNC device via an information carrier. After processing, the CNC device sends various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings. In the control of a three-dimensional CNC slide table, the PLC program needs to precisely plan the motion path. Existing technologies mostly rely on laser trackers or optical measurement systems to detect the trajectory, which suffers from expensive equipment and complex operation. Therefore, a simple and low-cost three-dimensional trajectory recording device is needed. Utility Model Content

The electronic induction pen is fixed to the end of the lifting mechanism through the mounting base, and the controller is electrically connected to the electronic induction pen for real-time acquisition and recording of the motion trajectory coordinates of the electronic induction pen in three-dimensional space.
[0005] Preferably, the first translation track achieves X-axis translation via a servo motor-driven pulley and transmission belt, the second translation track achieves Y-axis translation, and the lifting mechanism achieves Z-axis lifting.
[0006] Preferably, the mounting base is provided with a locking component, which clamps and fixes the pen barrel of the electronic pen by screwing.
[0007] Preferably, the mounting base is symmetrically provided with fixing members, the fixing members are connected to an arc-shaped plate, the arc-shaped plate covers the pen barrel of the electronic sensor pen, and a spring is sleeved on the fixing members.
[0008] Preferably, the locking member is threadedly connected to the side wall of the mounting base, and the locking member presses the fixing member with a knob so that the arc plate on the fixing member contacts the pen barrel of the electronic induction pen.
[0009] Preferably, the mounting base is connected to the lifting mechanism via a buffer pad to absorb vibration and impact during the movement of the lifting mechanism.
[0010] Compared with the prior art, this utility model has the following advantages:
[0011] By utilizing the basic motion structure of a 3D CNC slide table, an electronic induction pen is directly integrated as the core component for trajectory recording, replacing expensive laser trackers or optical measurement systems.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0022] like Figure 1-4 As shown, this utility model discloses a motion trajectory recording device based on a three-dimensional CNC slide table, including a machine tool body 1, a first translation rail 2 installed on the machine tool body 1, a second translation rail 3 provided on the movable base of the first translation rail 2, the second translation rail 3 being perpendicular to the first translation rail 2, a lifting mechanism 4 provided on the second translation rail 3, and also including an electronic pen 5 and a controller. The electronic pen 5 is fixed to the end of the lifting mechanism 4 through a mounting base 51, and the controller is electrically connected to the electronic pen 5 for real-time acquisition and recording of the motion trajectory coordinates of the electronic pen 5 in three-dimensional space.
[0023] Furthermore, the first translation track 2 achieves X-axis translation by driving the pulley 22 and transmission belt 211 through the servo motor 21, the second translation track 3 achieves Y-axis translation, and the lifting mechanism 4 achieves Z-axis lifting.
[0024] Furthermore, the mounting base 51 is provided with a locking component 511, which clamps and fixes the pen barrel of the electronic induction pen 5 by screwing.
[0025] Furthermore, the mounting base 51 is symmetrically provided with fixing members 512, the fixing members 512 are connected to the arc plate 513, the arc plate 513 covers the pen barrel of the electronic induction pen 5, and the fixing members 512 are fitted with springs 514.
[0026] Furthermore, the locking member 511 is threaded to the side wall of the mounting base 51, and the locking member 511 presses the fixing member 512 with a knob, so that the arc plate 513 on the fixing member 512 contacts the pen barrel of the electronic pen 5.
[0027] Furthermore, the mounting base 51 is connected to the lifting mechanism 4 via a buffer pad to absorb the vibration and impact of the lifting mechanism 4 during its movement.
[0028] The working principle of this utility model is as follows: When the equipment is running, the servo motor 21 drives the pulley 22 to drive the transmission belt 211, so that the first translation track 2 translates along the X-axis and drives the second translation track 3 to move; the second translation track 3 is also equipped with a servo motor and pulley, and the servo motor of the second translation track 3 drives the lifting mechanism 4 to move along the Y-axis of the second translation track; the mounting base 51 fixed to the end of the lifting mechanism 4 tightens the fixing member 512 by tightening the locking member 511, so that the arc plate 513 on the fixing member 512 tightly covers the pen barrel of the electronic induction pen 5 (where the spring 514 provides elastic preload), and the arc plates 513 at both ends fix the pen barrel; when the electronic induction pen 5 moves in three-dimensional space with the three-axis linkage, the controller collects and records its motion trajectory coordinates in real time.
