Abstract
Description
Technical Field
[0001] This utility model relates to the field of CNC lathe technology, specifically to a swing lathe tool setting device. Background Technology
[0002] In the field of lathe machining, the accuracy and efficiency of the tool setting process have always been key factors restricting the overall machining quality and production efficiency. With the rapid development of automation and precision measurement technologies, automated tool setting technology has emerged, aiming to break through the constraints of traditional tool setting methods and achieve fast and accurate tool setting operations. In the existing swing-type lathe tool setting technology, the drive mechanism of the swing arm usually adopts a cam-linkage combination mechanism for power transmission. The mechanism converts the rotational motion of the cam into the reciprocating swing of the swing arm through the transmission action of the link, thereby driving the measuring head to contact the tool and realize the measurement function.
[0003] However, the cam-linkage combination mechanism has many inherent defects in the power transmission process, which makes the swing arm very prone to instability when rotating. Specifically, when the cam rotates at a certain speed, the link is subjected to a variety of complex forces during the power transmission process, including inertial force, friction force, and additional forces caused by machining errors and assembly deviations. The interaction of these forces makes it difficult for the link's motion trajectory to accurately maintain the theoretical design state, which in turn causes fluctuations in the swing speed, amplitude, and acceleration of the swing arm. Therefore, we need to propose a swing lathe tool setting device. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5 This utility model provides a technical solution:
[0023] The oscillating lathe tool setter includes a power actuator 1, an oscillating mechanism 2, and a tool setting monitoring mechanism 3. The power actuator 1 is the power source of the entire tool setter, which directly determines the motion performance of the tool setter. The power actuator 1 includes a positioning base 101. The positioning base 101, as the basic support component of the power actuator, is made of high-strength and high-rigidity metal materials, such as cast iron or alloy steel, to ensure that it will not deform or be damaged when subjected to the torque generated by the drive motor 105 and the reaction force brought by the movement of the oscillating mechanism 2, thereby ensuring the overall stability of the tool setter.
[0024] The positioning base 101 has a reserved mounting cavity 102 inside, and the positioning shell 103 is installed inside the mounting cavity 102. The size and shape of the reserved mounting cavity 102 inside the positioning base 101 are precisely designed to fit tightly with the shape of the positioning shell 103. This not only provides a stable mounting position for the positioning shell 103, but also facilitates the installation and disassembly of the positioning shell 103, making subsequent maintenance and repair work convenient. The positioning shell 103 is also made of high-strength material, and the top of it is rotatably mounted with a high-precision bearing. This bearing has the characteristics of low friction and high load-bearing capacity, which can effectively reduce friction loss during the rotation of the driving gear 104, improve transmission efficiency, and at the same time ensure the smoothness and accuracy of the rotation of the driving gear 104.
[0025] The top of the positioning housing 103 is rotatably mounted with a drive gear 104. The drive gear 104 is connected to the drive motor 105 via a transmission shaft. The transmission shaft undergoes strict dynamic balancing to reduce vibrations generated during high-speed rotation and avoid adverse effects on the measurement accuracy of the tool setter. The bottom of the drive gear 104 passes through the positioning housing 103 via a transmission shaft and is connected to the drive motor 105. The drive motor 105 is a high-precision, low-noise servo motor. Its speed and direction can be precisely controlled by the lathe control system, thereby achieving precise adjustment of the rotation speed and direction of the drive gear 104 and providing precise power input for the subsequent movement of the swing mechanism 2.
[0026] The top of the drive gear 104 meshes with a planetary gear set 106. The planetary gear set 106, which meshes with the top of the drive gear 104, consists of multiple planetary gears, a sun gear, and a planet carrier. This structure enables multi-stage reduction and power distribution, allowing the oscillating mechanism 2 to obtain appropriate speed and torque to meet the tool setting requirements under different processing scenarios. In the power actuator 1, the top of the positioning housing 103 is rotatably mounted with the drive gear 104, and its bottom is connected to the drive motor 105 through a transmission shaft. The top of the drive gear 104 meshes with the planetary gear set 106. This design accurately transmits the power of the drive motor 105 to the planetary gear set 106 through gear meshing. The high precision characteristics of the gear transmission ensure the accuracy of the power transmission process and reduce energy loss and error accumulation during the power transmission process.
[0027] The swing mechanism 2 is a key component for realizing the measurement function of the swing lathe tool setter. It converts the power transmitted by the power actuator 1 into the swing motion of the swing arm 204. The swing mechanism 2 is connected to the planetary gear set 106. The tool setting monitoring mechanism 3 is installed at the end of the swing mechanism 2. The planetary gear set 106 can reasonably distribute the power, so that the swing mechanism 2 can obtain a stable and uniform power input. Compared with the power transmission method commonly used in traditional tool setters, the application of the planetary gear set 106 avoids the problem of unstable movement of the swing mechanism 2 caused by power fluctuations or uneven distribution, thereby greatly improving the reliability of the tool setter.
[0028] The swing mechanism 2 includes a fixed housing 201, which is mounted on top of the positioning housing 103. Both the fixed housing 201 and the positioning housing 103 have teeth 202 on their inner walls that are compatible with the planetary gear set 106. The planetary gear set 106 meshes with the teeth 202. The fixed housing 201 is mounted on top of the positioning housing 103, and the two are positioned and connected through high-precision mating surfaces and positioning pins to ensure the relative positional accuracy between them. This ensures that the planetary gear set 106 can accurately mesh with the teeth 202 on the inner walls of the fixed housing 201 and the positioning housing 103. Connecting members 203 are fixedly sleeved on the outer walls of the fixed housing 201 and the positioning housing 103. A swing arm 204 is connected to one side. The teeth 202 on the inner walls of the fixed shell 201 and the positioning shell 103 are precisely calculated and machined to ensure good meshing performance with the planetary gear set 106. This meshing method allows the planetary gear set 106 to drive the fixed shell 201 and the positioning shell 103 to rotate together during rotation. The connecting piece 203 fixedly sleeved on the outer walls of the fixed shell 201 and the positioning shell 103 rotates synchronously. The connecting piece 203 is made of high-strength and lightweight materials, such as aluminum alloy, to reduce its own weight as much as possible while ensuring structural strength, reducing the load on the power actuator 1, and improving the overall response speed of the tool setter.
[0029] The inner cavity of the connector 203 is provided with a static sealing ring 4. The static sealing ring 4 in the inner cavity of the connector 203 is made of high-quality rubber material, which has good elasticity and sealing performance. The cross-sectional shape of the static sealing ring 4 is specially designed so that it can fit tightly with the sealing surface of the inner cavity of the connector 203, effectively preventing external dust, cutting fluid and other impurities from entering the interior of the connector 203, avoiding wear and corrosion of moving parts such as the planetary gear set 106, and extending the service life of the tool setter. At the same time, the static sealing ring 4 can also play a certain role in buffering and shock absorption, reducing the impact of external vibration on the motion stability of the swing mechanism 2.
[0030] The fixed shell 201 is rotatably connected to the positioning base 101. The swing arm 204 connected to one side of the connecting part 203 is designed according to the measurement range of the tool setter and the size of the workpiece. The swing arm 204 is made of a material with high rigidity and low thermal expansion coefficient to reduce the impact of its own deformation and thermal expansion on the measurement accuracy during the movement. The fixed shell 201 and the positioning base 101 are rotatably connected through a high-precision rotating shaft and bearings. The rotating shaft is quenched and ground, with high surface hardness and low roughness. The bearings are high-precision angular contact ball bearings, which can withstand large radial and axial loads to ensure the smoothness and accuracy of the rotation of the fixed shell 201 relative to the positioning base 101.
[0031] The outer wall of the connector 203 is provided with a protrusion 5. One end of the swing arm 204 is fixedly inserted into the inside of the protrusion 5, and an O-ring 6 is provided inside the protrusion 5. The shape and size of the protrusion 5 on the outer wall of the connector 203 match the insertion part of one end of the swing arm 204. Through precise processing and assembly, it is ensured that the swing arm 204 can be firmly fixed inside the protrusion 5. The O-ring 6 inside the protrusion 5 is also made of high-performance rubber material. It can not only enhance the connection sealing between the swing arm 204 and the protrusion 5 and prevent dust and liquid from entering the connection part, but also play an elastic buffering role during the swing of the swing arm 204, reducing the vibration and loosening of the swing arm 204 caused by external impact, and ensuring the accuracy of the swing trajectory of the swing arm 204.
[0032] The tool setting monitoring mechanism 3 is the core component of the oscillating lathe tool setting instrument, enabling it to perform measurement functions. It can acquire the positional information between the tool and the workpiece in real time and accurately. The tool setting monitoring mechanism 3 includes a housing 301, a measuring head 302, and a data processing unit. The housing 301, serving as the outer shell of the tool setting monitoring mechanism 3, is made of high-strength, electromagnetic interference-resistant materials, such as stainless steel or engineering plastics, to protect the internal measuring head 302 and data processing unit from external environmental interference and damage. The housing 301 is fixedly connected to the end of the swing arm 204. The measuring head 302 is fixedly mounted on the outer wall of the housing 301. The data processing unit is located inside the housing 301. Depending on the different measurement requirements, the measuring head 302 can be selected from contact or non-contact sensors, such as inductive sensors, capacitive sensors or laser displacement sensors. These sensors have the characteristics of high precision, high resolution and high response speed, and can accurately detect the distance or position change between the tool and the workpiece, and convert the detected signal into an electrical signal output. The data processing unit is located in the inner cavity of the housing 301. It consists of a high-performance microprocessor, memory and signal conditioning circuit, and can quickly and accurately process and analyze the electrical signal output by the measuring head 302, calculate the actual position of the tool relative to the workpiece coordinate system, and output the result to the lathe control system in the form of digital signal or analog signal.
[0033] It also includes an indicator light 303. The outer wall of the housing 301 has a pre-reserved mounting groove that matches the indicator light 303. The indicator light 303 is fixedly embedded in the mounting groove. The indicator light 303 uses a high-brightness LED light with different colors and flashing modes, which can intuitively display the working status of the tool setter. For example, green indicates that the tool setter is completed, red indicates that the measurement is abnormal, and yellow indicates that the tool setter is in progress. Operators do not need complicated operations or professional knowledge. They can quickly understand the operation of the tool setter by simply observing the status of the indicator light 303 and make corresponding adjustments and handling in a timely manner.
[0034] It also includes a dust cover 304, which is detachably installed on the outer wall of the housing 301. The measuring head 302 is located in the inner cavity of the dust cover 304. The dust cover 304 is detachably installed on the outer wall of the housing 301 and is fixed by means of clips or screws, which makes it convenient for operators to install and remove. The dust cover 304 is made of transparent engineering plastic, which can protect the measuring head 302 from contamination by dust, chips and other impurities, without affecting the normal measurement work of the measuring head 302. At the same time, the surface of the dust cover 304 is treated with special anti-scratch treatment, which has good wear resistance and anti-aging properties, and can maintain transparency and cleanliness for a long time.
