Description

Technical Field

[0001] This utility model belongs to the field of power turret technology, specifically relating to a synchronous belt power transmission power turret with a Y-axis. Background Technology

[0002] In the current power turret industry, the power output structure mainly relies on gear transmission to transmit power from the power motor to the power head. However, this transmission structure has many obvious shortcomings: During transmission, gear meshing friction generates energy loss, and increased sliding and rolling friction reduces transmission efficiency, resulting in energy waste. Moreover, due to the limitations of the gear transmission structure, high-speed power output cannot be achieved. During operation, gear friction and bearing operation generate a large amount of heat in the gearbox. If heat dissipation is not timely, the internal temperature will rise, the viscosity of the lubricating oil will decrease, the lubrication performance will deteriorate, and the wear of gears and bearings will be accelerated, reducing the service life of the gearbox. At the same time, the gearbox structure is complex and requires extremely high machining precision. Substandard machining precision of parts or assembly errors will lead to increased vibration and noise during transmission, affecting the overall transmission performance. In addition, incorrect gear meshing will also generate significant noise, deteriorating the working environment and endangering the health of operators. This problem is even more prominent during high-speed operation. Furthermore, from research and development design and high-precision component manufacturing to complex assembly and debugging, power turret gearboxes require a large investment of manpower, material resources, and financial resources, resulting in high overall production costs. Utility Model Content

[0003] The purpose of this invention is to provide a synchronous belt power transmission turret with a Y-axis to solve the problems mentioned in the background art, such as low gear transmission efficiency and speed, poor heat dissipation, complex structure, high vibration and noise, and high overall production cost of existing power turrets.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a synchronous belt-driven power turret with a Y-axis, comprising a Y-axis support frame with a turret housing inside; a cutter head disposed at one end of the turret housing; a rear cover installed at the other end of the turret housing; a Y-axis lifting motor installed on the top of the Y-axis support frame, with a transmission component installed on the output end of the Y-axis lifting motor; a transmission assembly disposed inside the turret housing, a power motor disposed on one side of the turret housing, the power motor being connected to the transmission assembly, and the transmission assembly being connected to the cutter head, the power motor driving the transmission assembly, which in turn drives the cutter head; a locking assembly disposed inside the turret housing, adjacent to the cutter head, and a locking / unlocking inductive switch disposed inside the turret housing, adjacent to the locking assembly.

[0005] Preferably, the transmission assembly includes a first synchronous pulley and a second synchronous pulley, with a synchronous belt sleeved between the first and second synchronous pulleys. The first synchronous pulley is mounted on the output end of the power motor, and an output shaft support is mounted on the second synchronous pulley. An output shaft is mounted at the center of the output shaft support, and a power tool holder is mounted at the end of the output shaft. The power tool holder is installed inside the tool disc, thereby driving the first synchronous pulley through the power motor. The first synchronous pulley drives the second synchronous pulley and the output shaft to rotate through the synchronous belt, and finally drives the power tool holder to rotate through the output shaft, thus achieving the final machining.

[0006] Preferably, the locking assembly includes a piston-end gear plate connected to a hydraulic cylinder, responsible for locking and unlocking the entire locking assembly during tool changing to control the engagement and disengagement of the locking assembly; it also includes an indexing-end gear plate connected to the cutter head by screws and pins, which, driven by an indexing motor and a reduction gear structure, enables the cutter head to index, allowing it to accurately position itself to the required tool position; and a fixed-end gear plate fixed to the turret box, providing stable support and positioning reference for the entire locking assembly. This fixed-end gear plate, in conjunction with the lifting locking assembly and the indexing-end gear plate, completes the positioning and clamping of the cutter head. The fixed-end gear plate is located inside the indexing-end gear plate, and the two are concentrically arranged, while the piston-end gear plate and the indexing-end gear plate are centrally symmetrically distributed.

[0007] Preferably, the turret box is also equipped with a synchronous belt induction switch, which is located near the synchronous belt to sense the synchronous belt and automatically switch the power motor on and off.

[0008] Preferably, the transmission component is a lead screw, and a front bearing seat and a rear bearing seat are respectively provided at the connection between the lead screw and the turret box. A coupling is connected between the front bearing seat and the output end of the Y-axis lifting motor to achieve connection and torque transmission.

[0009] Preferably, the turret box is further provided with a tool changing speed reduction device, which is located above the transmission assembly.

[0010] Preferably, the turret box is further equipped with a tool changing servo motor, and the tool changing speed reducer is installed on the output end of the tool changing servo motor.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, a synchronous pulley and synchronous belt structure replaces the traditional gearbox transmission. This optimizes the shortcomings of gearbox transmission, such as low efficiency, high temperature rise, and high noise. It effectively solves the problem of heat generated by gear transmission causing thermal expansion of the cutter head and affecting machining accuracy. At the same time, changing the number of teeth on the synchronous pulley increases the output power, achieving high-speed and high-precision machining performance. The overall structure is simpler, greatly reducing the machining accuracy of parts and the assembly difficulty of finished products, thereby improving production efficiency and quality. Furthermore, the Y-axis lifting system's lead screw uses a fixed support method at both ends, allowing for pre-tensioning of the lead screw and improving the repeatability and reverse positioning accuracy of the lead screw transmission.

The power motor 300 drives the transmission assembly 105, and the transmission assembly 105 drives the cutter head 103 to achieve drive.

[0030] Inside the turret housing 102, there is also a locking assembly 400, which is located near the cutter head 103. Inside the turret housing 102, there is also a locking / releasing sensor switch 108, which is located near the locking assembly 400.

[0031] In this embodiment, preferably, the transmission assembly 105 includes a first synchronous pulley 301 and a second synchronous pulley 304. A synchronous belt 302 is sleeved between the first synchronous pulley 301 and the second synchronous pulley 304. The first synchronous pulley 301 is mounted on the output end of the power motor 300. An output shaft support 305 is mounted on the second synchronous pulley 304. An output shaft 303 is mounted at the center of the output shaft support 305. A power tool holder 306 is mounted at the end of the output shaft 303. The power tool holder 306 is installed inside the cutter disc 103. Thus, the power motor 300 drives the first synchronous pulley 301 to rotate. The first synchronous pulley 301 drives the second synchronous pulley 304 and the output shaft 303 to rotate through the synchronous belt 302. Finally, the output shaft 303 drives the power tool holder 306 to rotate, thereby achieving the final machining.

[0032] In this embodiment, preferably, the locking assembly 400 includes a piston-end gear plate 403, which is connected to a hydraulic cylinder and is responsible for locking and unlocking the entire locking assembly 400 during tool changing, thereby controlling the engagement and disengagement of the locking assembly 400; it also includes an indexing end gear plate 401, which is connected to the cutter head by screws and pins. Driven by the indexing motor and the reduction gear structure, it realizes the indexing action of the cutter head 103, enabling the cutter head 103 to... The required tool position and the fixed end gear plate 402 are accurately positioned. The fixed end gear plate 402 is fixed on the turret box 102, providing stable support and positioning reference for the entire locking assembly 400. It works in conjunction with the lifting locking assembly 400 and the indexing end gear plate 401 to complete the positioning and clamping of the tool head 103. The fixed end gear plate 402 is located inside the indexing end gear plate 401, and the two are arranged in a concentric circle. The piston end gear plate 403 and the indexing end gear plate 401 are distributed in a centrally symmetrical manner.

[0033] In this embodiment, preferably, the turret box 102 is also provided with a synchronous belt induction switch 106. The synchronous belt induction switch 106 is located near the synchronous belt 302 to sense the synchronous belt 302 and realize the automatic switching of the power motor 300.

After the tool changing reducer 104 reduces the speed and increases the torque, it drives the rear cover 101 to rotate to the tool selection position.

[0037] When changing tools:

[0038] When the machine tool receives a tool change command, the hydraulic cylinder drives the lifting end gear plate 400 to move, causing the three end gear plates to disengage from each other. At this time, the cutter head 103 is in a rotatable state. Then, the indexing motor drives the indexing gear to rotate, thereby driving the indexing end gear plate 401 and the cutter head 103 to rotate together, rotating the cutter head 103 to the designated tool position. The indexing motor is used to drive the indexing end gear plate 401.

[0039] When positioning and clamping:

[0040] After the cutter head 103 is in position, the CNC system sends a signal, and the hydraulic cylinder pushes the lifting end gear plate 400 to move in the opposite direction, so that the three end gear plates re-mesh, realize the locking action of the turret, complete the positioning and clamping of the cutter head 103, and ensure that the cutter head remains stable during the cutting process.
