Description

Technical Field

[0001] The utility model relates to the technical field of plate processing, and specifically relates to a carving spindle mechanism. Background Art

[0002] Stone processing is the process of processing natural stones into required shapes and surface effects through processes such as mining, cutting, grinding, and polishing. These processing steps can make the stones applicable to multiple fields such as architectural decoration and sculpture art, and enhance their aesthetics and functionality. A bridge cutting machine is a device dedicated to stone processing. Through a cutting device installed on a bridge, it can precisely cut stone blocks or plates to achieve the required dimensions and shapes.

[0003] With the continuous progress of technology, the original three-axis linkage bridge cutting equipment can only process some simple lines and shapes, which can no longer meet the current market demand. Therefore, a device with a rotating C-axis and A-axis is added on the original basis, and the five-axis bridge cutting machine is derived. The five-axis bridge cutting machine has a five-axis linkage cutting function, which can achieve one-time input and cutting of any angle of the stone. However, there are still a small number of processing processes that do not meet the requirements. Content of the Utility Model

[0004] The purpose of the utility model is to provide a carving spindle mechanism that can solve the deficiencies in the processing technology of traditional equipment.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows.

[0006] A carving spindle mechanism includes a C-axis frame. A first driving motor is installed on the outer surface of the C-axis frame. An A-axis frame is arranged inside the C-axis frame. A permanent magnet motor is installed inside the A-axis frame. A cutting blade is installed at the end of the output shaft of the permanent magnet motor. A connecting shaft is connected to the outer surface of the A-axis frame, and the end of the connecting shaft penetrates to the outside of the C-axis frame and is installed with a mounting plate. A lifting plate is installed on the outer surface of the mounting plate through a lifting mechanism. A carving spindle motor is installed on the outer surface of the lifting plate. The output shaft of the carving spindle motor is connected with a carving spindle tool, and the carving spindle tool is perpendicular to the cutting blade.

[0007] It can be seen that through the setting of the carving spindle, the equipment can achieve more complex stone processing, can carve fine textures or patterns. At the same time, during the processing process, the five-axis machine can achieve more precise angle and curved surface processing, which makes the processed stone works have better precision and aesthetics. And because the mounting plate is connected to the A-axis frame through the connecting shaft, and the carving spindle is perpendicular to the cutting blade, the cutting blade and the carving spindle do not interfere with each other, and the angles of the cutting blade and the carving spindle can be controlled by the first driving motor as needed.

[0008] Furthermore, the lifting mechanism includes a third driving motor installed on the top of the mounting plate. The end of the output shaft of the third driving motor is connected to a lead screw. A nut seat is installed on the outer surface of the lead screw, and the nut seat is connected to the lifting plate.

[0009] When the second driving motor is started, its output shaft drives the lead screw to rotate, which can drive the nut seat to move along its surface. Therefore, the purpose of driving the lifting plate to lift can be achieved, and the engraving depth can be adjusted according to needs, precisely controlling each engraving detail, improving the accuracy and meticulousness of processing.

[0010] Furthermore, linear guides are installed on both sides of the outer surface of the mounting plate, and sliders are installed on both sides of the outer surface of the lifting plate. The sliders are adapted to the linear guides.

[0011] Through the setting of the linear guides and sliders, the overall structural stability is enhanced, the vibration and deviation during processing are reduced, the processing quality is guaranteed, and the load can be effectively dispersed and reduced, reducing the wear of the system, thereby prolonging the service life of the equipment.

[0012] Furthermore, bearing seats are installed on both the upper and lower sides of the outer surface of the mounting plate, and the bearing seats are sleeved on the outer surface of the lead screw.

[0013] The setting of the bearing seats enables the lead screw to be better supported, reducing the bending and deformation of the lead screw, improving the stability of the equipment, ensuring the processing accuracy, and the uniformly distributed support points enhance the load-bearing capacity of the lead screw, enabling it to withstand greater processing pressure and weight, and improving the overall load-bearing capacity of the equipment.

[0014] Furthermore, the end of the output shaft of the first driving motor is connected to a planetary reducer, and the output shaft of the planetary reducer is connected to the A-axis frame.

[0015] The planetary reducer converts the high-speed rotation of the first driving motor into a lower working speed, enabling the equipment to perform precise processing at a lower speed, thereby improving the stability and controllability of processing. Moreover, the planetary reducer can significantly increase the output torque, providing sufficient power to meet the high-load processing requirements of hard stones.

[0016] Furthermore, a connection groove is provided at the top of the C-axis frame.

[0017] Through the setting of the connection groove, it can be connected to the rotating C-axis of the five-axis bridge cutting machine. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0023] The present utility model will be described in detail below with reference to the accompanying drawings.

[0024] As Figures 1-4 shown, an engraving spindle mechanism includes a C-axis frame 100, a first drive motor 101 is installed on the outer surface of the C-axis frame 100, an A-axis frame 102 is arranged inside the C-axis frame 100, a permanent magnet motor 103 is installed inside the A-axis frame 102, a cutting blade 104 is installed at the end of the output shaft of the permanent magnet motor 103, a connecting shaft 105 is connected to the outer surface of the A-axis frame 102, and the end of the connecting shaft 105 penetrates to the outside of the C-axis frame 100 and is installed with a mounting plate 106. A lifting plate 109 is installed on the outer surface of the mounting plate 106 through a lifting mechanism 200. An engraving spindle motor 107 is installed on the outer surface of the lifting plate 109. The output shaft of the engraving spindle motor 107 is connected with an engraving spindle tool 108, and the engraving spindle 108 is perpendicular to the cutting blade 104.

[0025] During use, the main shaft mechanism is connected to the rotating C-axis of the five-axis bridge cutting machine. The cutting blade 104 is controlled by the permanent magnet motor 103 to rotate for cutting the plate, and the engraving spindle 108 is controlled by the second driving motor 107 to rotate for engraving and edge grinding of the plate. Complex patterns and detailed engravings can be completed, providing a more refined processing ability than the cutting blade 104. The edges of the plate can be carefully polished to remove burrs and irregular edges, making the edges smooth and flat, increasing the flexibility and functionality of the device processing. It is applicable to various complex geometric shape and curve cutting requirements, as well as surface and profiling processing, and solves the problems existing in the current processing technology. Since the mounting plate 106 is connected to the A-axis frame 102 through the connecting shaft 105, and the engraving spindle 108 and the cutting blade 104 are perpendicular to each other, the cutting blade 104 and the engraving spindle 108 do not interfere with each other. Therefore, the angles of the cutting blade 104 and the engraving spindle 108 can be controlled by the first driving motor 101.

[0026] Specifically, the lifting mechanism 200 includes a second driving motor 201 installed on the top of the mounting plate 106. The end of the output shaft of the second driving motor 201 is connected with a lead screw 202. A nut seat 203 is installed on the outer surface of the lead screw 202, and the nut seat 203 is connected with the lifting plate 109. When the second driving motor 201 is started, its output shaft drives the lead screw 202 to rotate, which can drive the nut seat 203 to move along its surface. Therefore, the purpose of driving the lifting plate 109 to lift can be achieved, and the engraving depth can be adjusted according to needs, accurately controlling each engraving detail, and improving the accuracy and meticulousness of processing.

[0027] Specifically, linear guides 300 are installed on both sides of the outer surface of the mounting plate 106, and sliders 301 are installed on both sides of the outer surface of the lifting plate 109. The sliders 301 are adapted to the linear guides 300. Through the setting of the linear guides 300 and the sliders 301, the overall structural stability can be enhanced, the vibration and deviation during the processing can be reduced, the processing quality can be guaranteed, and the load can be effectively dispersed and reduced, reducing the wear of the system, thereby extending the service life of the equipment.

[0028] Specifically, bearing seats 400 are installed on the upper and lower sides of the outer surface of the mounting plate 106. The bearing seats 400 are sleeved on the outer surface of the lead screw 202. The setting of the bearing seats 400 enables the lead screw 202 to be better supported, reduces the bending and deformation of the lead screw 202, improves the stability of the equipment, ensures the processing accuracy, and the uniformly distributed support points enhance the load-bearing capacity of the lead screw 202, enabling it to withstand greater processing pressure and weight, and improving the overall load-bearing capacity of the equipment.

[0029] Specifically, the end of the output shaft of the first drive motor 101 is connected to a planetary speed reducer 500. The output shaft of the planetary speed reducer 500 is connected to the A-axis frame 102. The planetary speed reducer 500 converts the high-speed rotation of the first drive motor 101 into a lower working speed, enabling the equipment to perform precise machining at a lower speed, thereby improving the stability and controllability of the machining. Moreover, the planetary speed reducer 500 can significantly increase the output torque and provide sufficient power to meet the high-load machining requirements of hard stones.

[0030] Specifically, a connection groove 600 is provided at the top of the C-axis frame 100. Through the setting of the connection groove 600, it can be connected to the rotating C-axis of the five-axis bridge cutting machine.

It cannot be determined that the specific implementation modes of the present invention are only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several equivalent substitutions or obvious modifications are made, and the performance or use is the same, and all should be regarded as belonging to the patent protection scope determined by the claims submitted by the present invention.
