Description

Technical Field

[0001] The utility model belongs to the field of numerical control machine tools, in particular to a numerical control three-dimensional five-axis and single-knife angle tool holder. Background Art

[0002] In existing rolling mill processes, the tool's movement during the cutting process is restricted. This is primarily due to the inability to flexibly move in multiple dimensions and adapt to changes in the inclination of the workpiece axis, leading to the technical problem of not being able to achieve three-dimensional curved surface machining. Existing CNC equipment typically only has the ability to move in a single direction or a limited number of dimensions, such as only being able to move horizontally or vertically, and cannot freely adjust the tool position in multiple directions simultaneously. This limitation makes it difficult to accurately position the tool and perform complex surface cutting operations during machining, making it impossible to meet the requirements of high-precision and complex shape machining, affecting the surface quality and machining efficiency of the product. Utility Model Content

[0012] The beneficial effects achieved by the utility model using the above structure are as follows:

[0015] In a specific embodiment of the present invention, the lateral and longitudinal motion assemblies, through the coordination of a motor and a slide rail system, enable free movement of the tool along the X and Y axes. The introduction of a vertical motion assembly enables adjustment of the tool along the Z axis, enabling free positioning within three-dimensional space. The design of the tool holder assembly further enhances tool stability and motion accuracy, enabling precise control of the spindle through the coordination of a worm and worm gear.

Therefore, they cannot be understood as limitations on the present invention.

[0024] Example:

[0025] See also Figure 1-Figure 3A CNC three-dimensional five-axis and single-tool angle tool holder includes a base 1, a lateral movement component 3 is installed on the base 1, a longitudinal movement component 5 is installed on the lateral movement component 3, a fixed seat 8 is installed on the longitudinal movement component 5, a vertical movement component 6 is installed on the fixed seat 8, a tool holder assembly 7 is installed on the vertical movement component 6, and a drive assembly 9 is installed on the tool holder assembly 7.

[0026] In the above scheme, the entire device is supported by a base 1. The lateral motion assembly 3 enables lateral movement of the tool holder, the longitudinal motion assembly 5 achieves longitudinal movement, and the vertical motion assembly 6 controls vertical movement. This multi-dimensional movement allows the tool to be flexibly adjusted, meeting the needs of complex machining operations and improving machining accuracy and efficiency. The drive assembly 9 ensures precise movement and stability of the tool in all directions by controlling the motors of each component.

[0027] Furthermore, the lateral movement component 3 includes a first motor 2 installed on the base 1, a first slide rail 302 is fixed on the base 1, a first slide seat 301 is slidably provided on the first slide rail 302, a first screw 303 is installed at one end of the first motor 2, and the first screw 303 is transmitted and matched with the first slide seat 301.

[0028] The lateral movement assembly 3 operates by rotating the first screw 303 via the first motor 2, which drives the first slide 301 to slide along the first slide rail 302, thereby achieving precise lateral movement of the tool holder. This design ensures that the tool can move laterally along a predetermined path during machining, meeting diverse machining requirements.

[0029] See also Figure 1-Figure 3 The longitudinal moving component 5 includes a second motor 501 mounted on the first slide 301, a second slide rail 502 is mounted on the first slide 301, a fixed seat 8 is slidably provided on the second slide rail 502, and a second screw 503 is mounted at one end of the second motor 501.

[0030] In the above solution, the longitudinal movement assembly 5 operates by rotating the second screw 503 via the second motor 501, which drives the fixed base 8 to slide along the second slide rail 502, thereby achieving longitudinal movement of the tool holder. This assembly design allows the tool to be flexibly adjusted in the longitudinal direction during machining, improving the tool's adaptability to the workpiece and machining accuracy.

[0031] Furthermore, the vertical motion assembly 6 includes a third motor 601 mounted on the fixing seat 8 , and a third screw 602 is mounted on one end of the third motor 601 .

[0032] In the above solution, the vertical motion assembly 6 operates by rotating the third screw 602 via the third motor 601, thereby moving the tool holder assembly 7 vertically. This assembly design allows for height adjustment of the tool during machining, meeting the vertical positioning requirements of various machining operations and achieving more precise machining results.

[0033] Furthermore, the tool holder assembly 7 includes a tool holder box 703 mounted on the fixing seat 8 , and the threaded screw of the tool holder box 703 is driven to cooperate with the third screw 602 .

[0034] The tool is stably moved in the vertical direction by the threaded screw transmission between the tool holder box 703 and the third screw 602. The design of the tool holder box 703 ensures the positioning accuracy of the tool during the machining process and can support the installation of the drive assembly 9, further improving the stability and reliability of the machining operation.

[0035] See also Figure 1-Figure 3 The driving assembly 9 includes a fourth motor 901 mounted on the tool holder box 703 , and a first worm 902 is driven at one end of the fourth motor 901 .

[0036] In the above solution, the operating principle of the drive assembly 9 is to drive the first worm 902 to rotate via the fourth motor 901, thereby controlling the rotation or other operation of the tool. This design enables the tool to achieve precise movement and operation during the machining process, further enhancing the flexibility and functionality of the machining process.

[0037] See also Figure 1-Figure 3 The tool holder box 703 is provided with a first main shaft 701 , and one end of the first main shaft 701 is provided with a first worm gear 704 .

[0038] The first spindle 701 in the tool holder box 703 cooperates with the first worm gear 704 to realize the rotation or other operations of the tool. This component design enables the tool to maintain stable rotation during the processing, ensuring the accuracy and consistency of the processing.

[0039] Specifically, the first worm wheel 704 is drivingly engaged with the first worm 902 .

[0040] The transmission cooperation between the first worm wheel 704 and the first worm 902 realizes the precise control of the tool. This design ensures that the tool can perform the required rotation operation during the machining process, thereby meeting the needs of various complex machining tasks.

[0041] Its overall working principle is to use the base 1 as the basic support, and sequentially configure the lateral movement component 3, the longitudinal movement component 5 and the vertical movement component 6, so that the tool holder can move precisely in three different directions: lateral, longitudinal and vertical.

[0042] Specifically, the transverse movement assembly 3 rotates the first screw 303 via the first motor 2, causing the first slide 301 to slide on the first slide rail 302 on the base 1, thereby achieving transverse movement of the tool holder. The longitudinal movement assembly 5, on the other hand, drives the second screw 503 via the second motor 501, causing the fixed base 8 to slide on the second slide rail 502 on the first slide 301, thereby achieving longitudinal movement.

[0043] The vertical motion assembly 6 drives the third screw 602 via the third motor 601, moving the tool holder assembly 7 vertically for height adjustment. The tool holder housing 703 within the tool holder assembly 7 ensures stable vertical movement of the tool through a threaded screw drive coupled with the third screw 602. The drive assembly 9 drives the first worm 902 via the fourth motor 901. This worm 902 cooperates with the first worm gear 704 within the tool holder housing 703 to control the rotation and other operations of the tool.

[0044] In general, the CNC three-dimensional five-axis and single-tool angle tool holder enables precise movement in all directions and coordination with the drive device, allowing the tool to be flexibly adjusted and operated in multiple dimensions to meet the high-precision processing requirements of complex workpieces.
