Description

Technical Field

[0001] The utility model relates to the technical field of tool magazine transmission systems, in particular to a tool magazine tool changing system driven by a servo motor and a synchronous wheel. Background Art

[0002] The current drive system for tool magazines on machining centers utilizes a conventional brake motor connected to a sprocket assembly, which drives a cylindrical cam assembly. Because the use of a conventional motor with a brake system and a sprocket assembly for transmission has raised concerns about positioning accuracy, a linear arc is added to the drum cam to create a pause in operation to ensure accurate positioning of the tool magazine's tool disc at each fixed point.

[0003] The prior art, CN2023213068844, a stop-point cylindrical cam roller bearing tool magazine tool changing system, uses a conventional motor with a brake to drive a set of sprockets as its transmission method. Its positioning method relies on a cylindrical cam with a linear stop point to accurately position it at each tool cup action point to complete each tool change action. When the cylindrical cam with a stop point is used for skipping or long-interval tool changes, it will wobble during operation due to the roller passing through the stop curve in the cam's actuation path, affecting the service life of the machine tool tool magazine.

[0004] Therefore, it is necessary to design a servo motor driven synchronous wheel transmission tool magazine tool changing system to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a servo motor driven synchronous wheel transmission tool magazine tool changing system to overcome the above-mentioned deficiencies in the current prior art.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] The camshaft is a gear mounted on the drive means and is adapted to move the drive means to the drive means and to move the drive means to the drive means.

[0008] Preferably, it also includes a plurality of cutter cups distributed in an annular manner on the cutter disc, a fixing plate fixed to the end of the cutter disc main shaft, and a cutter cup positioning assembly fixed to the fixing plate.

[0009] Preferably, the knife cup positioning assembly includes a cylinder fixed on a fixed plate and a knife cup clamping block driven by the cylinder to move up and down.

[0010] Preferably, a main transmission bearing is provided outside the cutter disc support shaft, and the cutter disc is placed outside the main transmission bearing.

[0011] Preferably, the main transmission synchronous wheel and the passive transmission synchronous wheel are alternately arranged on the motor fixing plate, and the tension adjustment synchronous wheel is placed below the passive transmission synchronous wheel.

[0012] The beneficial effect of the present invention is that the present technical solution changes the transmission mode from the general motor with brake mode to the motor plus synchronous belt transmission mode, so that the main drive does not need to set a stagnation point, regardless of the positioning accuracy and the operation of the cutter disc without pauses, and also extends the service life of the tool magazine.

[0017] Reference Figure 1 A servo motor driven synchronous wheel transmission tool magazine tool changing system comprises a tool magazine base 1, a tool disk 2 mounted on the tool magazine base via a tool disk support shaft 21, and a synchronous wheel transmission assembly 3 mounted on the tool magazine base and used to drive the tool disk to rotate;

[0018] The cutterhead also includes a plurality of cutting cups 4 arranged in an annular pattern, a fixing plate 5 secured to the end of the cutterhead's main shaft, and a cutting cup positioning assembly 6 secured to the fixing plate. The cutting cup positioning assembly comprises a cylinder 61 secured to the fixing plate and a cutting cup clamp 62 driven up and down by the cylinder. The cylinder drives the clamp into the cutting cup, securing the cutterhead and the corresponding cutting tool, allowing the device to be used.

[0019] In order to effectively rotate the cutter disc 2, a main transmission bearing 22 is provided outside the cutter disc support shaft 21, and the cutter disc 2 is placed outside the main transmission bearing 22 to achieve rotation;

[0020] The synchronous wheel transmission assembly 3 includes a driven synchronous wheel 31 installed on the rear side of the cutter disc, a motor fixing plate 32 installed on the tool magazine base 1, a main transmission synchronous wheel 33 arranged on the motor fixing plate, a motor 39 driving the main transmission synchronous wheel 33 to rotate, a passive transmission synchronous wheel 35 installed on the motor fixing plate through a passive synchronous wheel shaft 34 and a bearing, a tension adjustment synchronous wheel 37 installed on the motor fixing plate through a tension adjustment synchronous wheel shaft 36 and a bearing, and a double-sided synchronous belt 38 wrapped around the main transmission synchronous wheel, the passive transmission synchronous wheel, and the tension adjustment synchronous wheel and meshing with the driven synchronous wheel 31; the double-sided synchronous belt 38 drives the driven synchronous wheel 31 to rotate, thereby driving the cutter disc to rotate, thereby improving the transmission accuracy.

[0021] The main transmission synchronous wheel 33 and the passive transmission synchronous wheel 35 are staggered on the motor fixing plate 32, and the tension adjustment synchronous wheel 37 is placed below the passive transmission synchronous wheel 35;

[0022] In this embodiment, the motor 39 drives the main transmission synchronous wheel 33 to rotate, and at the same time drives the double-sided synchronous belt 38 to rotate around the main transmission synchronous wheel, the passive transmission synchronous wheel, and the tension adjustment synchronous wheel. Since the double-sided synchronous belt 38 is directly engaged with the driven synchronous wheel, and the cutter disc is installed through the main transmission bearing and the cutter disc support shaft 21, the double-sided synchronous belt 38 drives the driven synchronous wheel to rotate, thereby driving the cutter disc to rotate, thereby realizing rotation and tool change.

[0023] The benefit of this utility model is that this technical solution changes the transmission mode from the general motor with brake mode to the motor plus synchronous belt mode, so that the main drive does not need to set a stagnation point, regardless of the positioning accuracy and the operation of the cutter disc without pauses, and also extends the service life of the tool magazine.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
