Description

Technical Field

[0001] This utility model relates to the field of machine tools, and in particular to a slide table with an integrated built-in motor direct drive power tower. Background Technology

[0002] In modern manufacturing, more and more companies are focusing on production efficiency and quality. To achieve this goal, machine tools have gradually evolved into intelligent tools that are high-speed, high-precision, and highly flexible. As an accessory for machine tools, the power turret has attracted much attention due to its reliability and significant contribution to improving machining efficiency. A power turret is a device used to automatically change different turning / milling / drilling functional modules (such as various chucks and fixtures). Compared to traditional manually disassembled tool holders, power turrets save time and strictly control accuracy, allowing for rapid changes to the next operation during continuous operation.

[0003] A search of Chinese patents revealed publication number CN217889530U, which discloses a power turret comprising a turret body, a tool holder, a drive device, and a locking device. The tool holder is rotatably connected to the turret body. The drive device includes a gear ring and a first drive component. The gear ring is fixedly sleeved on the tool holder, and the first drive component drives the gear ring to rotate. The locking device includes a second drive component, a double gear disc, and a movable gear disc. The movable gear disc is coaxially fixed on the tool holder, and the second drive component drives the double gear disc to move within the turret body. The opposing tooth surfaces of the double gear disc and the movable gear disc can mesh with each other. The gear ring is coaxially fixedly sleeved on the movable gear disc. A clearance groove is provided on the outer wall of the turret body, located on the side of the gear ring, the double gear disc, and the movable gear disc away from the tool holder. The design minimizes the space occupied by the gear ring, the movable gear disc, and the double gear disc within the turret body, leaving space for the clearance groove and thus increasing the applicability of the power turret.

[0004] The traditional turret structure currently in use mainly relies on a servo motor to drive a reducer for tool rotation. Traditional turret structures are complex, requiring large installation space for components, resulting in a large turret size and excessive length. The addition of a reducer creates an extra transmission link, leading to problems such as low transmission accuracy and large transmission backlash. Moreover, the cost is high. In traditional turret structures, the tool cooling valve assembly and piping rub against the tool disc during tool changes, affecting their service life. To solve the above problems, we propose an integrated slide table with a built-in motor and direct drive force turret. Utility Model Content

[0005] The purpose of this invention is to provide an integrated slide table with a built-in motor direct drive power tower, which has the advantages of high transmission accuracy, suitability for high-precision machining environments, and no friction with the tool head during tool changes.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an integrated slide table with a built-in motor direct-drive turret, including a turret housing, characterized in that a rear cover plate is bolted to the surface of the turret housing, a tool cooling valve is installed on the surface of the turret housing, a pipe interface is installed on the surface of the rear cover plate, a turret spindle is rotatably sleeved on the inner wall of the turret housing, an oil passage and a first cooling pipe are provided inside the turret spindle, one end of the oil passage and the first cooling pipe are connected to the pipe interface, and the other end of the first cooling pipe is connected to the tool cooling valve group, a tool disc is installed on one side of the turret housing, a second cooling pipe is provided inside the tool disc, and the second cooling pipe is connected to the cooling valve group, a locking position sensor and a separation position sensor are installed on the inner wall of the turret housing, a power motor is installed inside the tool disc, a connecting shaft is installed at the output end of the power motor, and the connecting shaft is rotatably sleeved with the inner wall of the tool disc, and an encoder is installed on the surface of the power motor.

[0007] By adopting the above technical solution and through the special design of the tool cooling valve group, the connection between the cooling valve group and the tool disc is separated during tool change. The water nozzle of the tool valve group does not rub against the tool disc during tool change. At the same time, the tool cooling water can be automatically shut off when the tool is retracted into place, without the need for signal control from the host computer. This achieves the goal of not stopping the cooling water pump and providing high-pressure water in real time when the tool is retracted into place, thus improving the service life.

[0008] The present invention is further configured such that: a ratchet chuck fixed plate and a ratchet chuck locking plate are installed between the turret housing and the turret spindle; a locking oil chamber is provided between the ratchet chuck fixed plate and the ratchet chuck locking plate, and the locking oil chamber is connected to the oil circuit; a tool changer reduction motor is installed on the inner wall of the turret housing; a tool changer servo motor is installed on the surface of the tool changer reduction motor; a pinion is fixedly sleeved on the output end of the tool changer reduction motor; a ratchet chuck moving plate is meshed on the surface of the pinion; the ratchet chuck moving plate is installed on the surface of the ratchet chuck fixed plate; and the tool disc is installed on the surface of the ratchet chuck moving plate.

[0009] By adopting the above technical solution, the use of direct motor drive eliminates the problems of power torque loss, gear wear, and large gear clearance that occur with bevel gear transmission. This reduces the internal space occupied by the traditional power turret in the machine tool. The high-precision encoder provides real-time feedback on speed, direction, and position, enabling higher positional accuracy, rotational accuracy, and depth control during rigid tapping, resulting in higher surface roughness of the machined parts.

[0010] The present invention is further configured such that a sliding platform is bolted to the surface of the turret.

[0011] By adopting the above technical solution and setting up a sliding table, installation and fixation are facilitated.

[0012] The present invention is further configured such that a lifting ring is bolted to the surface of the turret shell.

[0013] By adopting the above technical solution and setting up lifting rings, lifting is facilitated.

[0014] The present invention is further configured such that a sealing ring is provided between the spindle and the inner wall of the turret housing.

[0015] By adopting the above technical solution, the sealing performance is improved by setting a sealing ring.

[0016] The present invention is further configured such that a front cover plate is bolted to the surface of the cutter head.

[0017] By adopting the above technical solution, the power motor in the cutter head is protected by setting a front cover plate.

[0018] The present invention is further configured such that a tool holder anti-movement disc is installed inside the tool disc.

[0019] By adopting the above technical solution, the stability of the tool turret is ensured by setting an anti-movement disc on the tool holder.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. This utility model adopts direct motor drive, eliminating the problems of power torque loss, gear wear, and large gear clearance that occur with bevel gear transmission. It also reduces the internal space occupied by the traditional power turret in the machine tool. The high-precision encoder provides real-time feedback on speed, direction, and position, enabling high positional accuracy, rotational accuracy, and depth control during rigid tapping, resulting in a high surface roughness of the machined parts.

[0022] 2.

At the same time, it can automatically shut off the tool cooling water when it retracts to the correct position, without the need for signal control from the host computer. This achieves the goal of stopping the cooling water pump without stopping the machine, and high-pressure water is discharged in real time when the tool is changed, thus improving the service life.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Example 1:

[0034] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8The slide-integrated built-in motor direct drive turret includes a turret housing 1, a rear cover plate 2 bolted to the surface of the turret housing 1, a tool cooling valve 3 mounted on the surface of the turret housing 1, and a pipe interface 4 mounted on the surface of the rear cover plate 2. A turret spindle 5 is rotatably sleeved on the inner wall of the turret housing 1.

The inner wall of body 1 is equipped with a locking position sensor 10 and a separation position sensor 11. The inside of the cutter head 8 is equipped with a power motor 12. The output end of the power motor 12 is equipped with a connecting shaft 13, and the connecting shaft 13 is rotatably sleeved with the inner wall of the cutter head 8. An encoder 14 is installed on the surface of the power motor 12. Through the special design of the tool cooling valve group 3, the connection between the cooling valve group and the cutter head 8 is separated during tool change. During tool change, the water nozzle of the tool valve group does not rub against the cutter head 8. At the same time, the tool cooling water can be automatically shut off when the tool is retracted into position, without the need for signal control from the host computer. This achieves the goal of stopping the cooling water pump without the need for the machine to stop. High-pressure water is discharged in real time when the tool is retracted into position, which improves the service life.

[0035] refer to Figure 1 , Figure 2 and Figure 4 A slide 23 is bolted to the surface of the turret housing 1, which facilitates installation and fixation.

[0036] Reference image and Figure 1 , Figure 2 , Figure 3 and Figure 4 The surface of the turret housing 1 is bolted with a lifting ring 24, which facilitates lifting.

[0037] refer to Figure 4 A sealing ring 25 is provided between the turret spindle 5 and the inner wall of the turret housing 1 to improve the sealing performance.

[0038] Example 2:

[0039] refer to Figure 4 and Figure 5A ratchet caliper fixed plate 16 and a ratchet caliper locking plate 17 are installed between the turret housing 1 and the turret spindle 5. A locking oil chamber 18 is provided between the ratchet caliper fixed plate 16 and the ratchet caliper locking plate 17, and the locking oil chamber 18 is connected to the oil circuit 6. A tool changer reduction motor 19 is installed on the inner wall of the turret housing 1. A tool changer servo motor 20 is installed on the surface of the tool changer reduction motor 19. A pinion 21 is fixedly sleeved at the output end of the tool changer reduction motor 19. A ratchet caliper moving plate 22 meshes with the surface of the pinion 21. 2 is installed on the surface of the fixed plate 16 of the ratchet turret, and the cutter head 8 is installed on the surface of the moving plate 22 of the ratchet turret. By adopting direct motor drive, there is no bevel gear transmission, which eliminates the problems of power torque loss, gear wear, and large gear clearance that would occur with bevel gear transmission. This reduces the internal space occupied by the traditional power turret. The high-precision encoder 14 provides real-time feedback on speed, direction, position, etc., which can achieve high positional accuracy, rotational accuracy, and depth control during rigid tapping, resulting in a high surface roughness of the machined parts.

[0040] refer to Figure 1 and Figure 4 A front cover plate 26 is bolted to the surface of the cutter head 8. The front cover plate 26 protects the power motor 12 in the cutter head 8.

[0041] refer to Figure 4 and Figure 8 The cutter head 8 is equipped with a tool holder anti-movement plate 15. By setting the tool holder anti-movement plate 15, the stability of the cutter head 8 is ensured.

[0042] Brief description of the operation: The host computer sends a tool change signal, specifying the required tool turret position 8. The hydraulic station supplies oil to the separation chamber of the separation locking cylinder through pipelines and the built-in oil passages of the turret body. After the separation locking cylinder receives oil, it drives the ratchet locking plate 17 to move backward to separate from the ratchet moving plate 22 and the ratchet fixed plate 16, which are designed with positioning grooves, thus completing the separation action. The ratchet moving plate 22 is designed with a displacement mechanism that moves back and forth simultaneously with it. The end of the displacement mechanism is designed with a detection signal probe to detect separation and locking, and sends a signal back to the host computer to indicate whether the separation is in place. Once the machine receives an accurate signal confirming the separation of the locking disc 17, the tool changer servo motor 20 is energized, driving the gear directly connected to the tool changer motor to rotate. Simultaneously, the rotating gear drives the meshing ratchet disc 22, which is connected to the tool disc 8 via bolts. Therefore, when the pinion 21 of the tool changer motor rotates, the gear on the outer diameter of the meshing ratchet disc 22 also rotates. Since the ratchet disc 22 is connected to the tool disc 8 via bolts, the tool disc 8 also rotates. Once the tool disc 8 reaches the designated position, the tool changer servo motor 20... After the tool change servo motor 20 drives the tool disc 8 to rotate to the designated position, the host computer monitors the positioning signal and continues to execute the positioning locking action. Once the host computer issues a locking signal, the hydraulic station supplies oil to the locking chamber of the separation locking cylinder through pipelines and the internal oil passages of the turret body. After oil enters the locking chamber of the separation locking cylinder, it drives the ratchet plate locking plate 17 to move forward, engaging with the ratchet plate moving plate 22 and the ratchet plate fixed plate 16, accurately locking into the positioning grooves of each ratchet plate, completing the locking action. The ratchet plate moving plate 22 is designed with a displacement mechanism that moves back and forth simultaneously with it. The end of the tool is designed with a detection signal probe for detecting separation and locking, and feeds back the locking signal to the host computer. When the host computer receives the locking signal, the entire tool changing process ends. It adopts direct motor drive, without bevel gear transmission, and avoids the problems of power torque loss, gear wear, and large gear clearance that will occur with bevel gear transmission. It reduces the internal space occupied by the traditional power turret. The high-precision encoder 14 provides real-time feedback on speed, direction, position, etc., which can achieve high positional accuracy, rotational accuracy, and depth control during rigid tapping, so that the machined parts can achieve high surface roughness.The power motor 12 has a circulating cooling oil inlet. After oil enters, it connects to the cooling pipes designed on the turret spindle 5 via a pipeline. Then, the flow direction of the cooling oil is changed through a through-hole on the housing connecting plate connected to the turret spindle 5. The oil then flows into the power motor 12 housing through another through-hole on the housing connecting plate, cooling the power motor 12 via a cooling water oil passage designed on the motor 12. Finally, it returns to the designed return oil cooling pipes on the turret spindle 5 through a return oil through-hole on the housing connecting plate, and is cooled by the oil cooler at the circulating cooling return oil interface of the power motor 12. Through the special design of the tool cooling valve group 3, the connection between the cooling valve group and the tool disc 8 is separated during tool changing, preventing friction between the tool valve group water nozzles and the tool disc 8. Furthermore, the tool cooling water is automatically shut off when the valves are retracted to the correct position, without the need for a host computer signal control. This achieves real-time high-pressure water output without stopping the cooling water pump, improving service life.
