Description

Technical Field

[0001] This utility model relates to the field of CNC quenching tools, and in particular to a CNC quenching machine tool. Background Technology

[0002] Quenching is an important metal heat treatment process. By heating a metal workpiece to a certain temperature and then rapidly cooling it, the hardness, strength, and wear resistance of the metal are significantly improved. It is widely used in many fields such as machinery manufacturing, automotive industry, and aerospace. Traditional quenching equipment has played an important role in meeting the needs of industrial production. However, with the continuous development of industrial technology, higher requirements have been placed on the performance, precision, and efficiency of quenching equipment.

[0003] Common quenching devices typically install the workpiece in a fixed position and then move the device to adapt to the processing location. This mechanism requires the temperature control device to change height along with the quenching device. However, since the temperature control device includes not only heating rings but also water pipes for cooling, the water pipes can become entangled and damaged during the raising and lowering process, increasing production costs. Furthermore, traditional quenching devices have limited control precision. For workpieces of different shapes, sizes, and materials, it is difficult to accurately control various parameters during the quenching process, such as heating temperature, holding time, and cooling rate. Inaccurate control of these parameters can lead to uneven internal structure of the workpiece, affecting its final mechanical properties and potentially causing defects such as deformation and cracking, thus reducing the product qualification rate. Therefore, these problems need to be addressed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a CNC quenching machine tool.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a CNC quenching machine tool, comprising a quenching box and a support frame installed inside the quenching box, slide rails installed on both sides of the support frame, a lifting mechanism installed on the slide rails, a positioning mechanism installed at the upper end of the lifting mechanism, a quenching mechanism installed at the bottom end of the lifting mechanism, and a temperature regulating mechanism installed on the inner side of the quenching box, the temperature regulating mechanism being located on one side of the support frame.

[0006] Preferably, the lifting mechanism includes three connected sliding plates slidably mounted on a slide rail and a first motor mounted on the top of a support frame. The output shaft of the first motor is connected to a first lead screw via a coupling. A first mounting block is threaded onto the first lead screw. The first mounting block is connected to the sliding plate in the middle position. A linear motor cooperating with the lifting mechanism is mounted on one side of the support frame, and a first mounting platform is fixed to the front end of the upper sliding plate.

[0007] Preferably, the positioning mechanism includes a second motor mounted on a first mounting platform, a second lead screw mounted on the output shaft of the second motor via a coupling, the bottom end of the second lead screw mounted on a lower sliding plate, and a second mounting platform threaded onto the second lead screw. A pressure cylinder is mounted on the second mounting platform, and a positioning drill bit is mounted on the bottom end of the pressure cylinder.

[0008] Preferably, the quenching mechanism includes a third motor installed on one side of the second motor. The third motor has a rotating shaft installed on it via a coupling. A first gear is fixed to the bottom end of the rotating shaft. A second gear is installed at the front end of the first gear. A transmission belt is sleeved on the first gear and the second gear. A quenching pile is installed on the upper end of the second gear. A quenching drill bit is installed on the top end of the quenching pile.

[0009] Preferably, a tension adjuster is installed on one side of the transmission belt, and the diameter of the second gear is larger than the diameter of the first gear.

[0010] Preferably, the temperature regulating mechanism includes a mounting lug installed on an inner side of the quenching chamber and multiple drain pipes, each drain pipe having a valve installed on it, and the mounting lug having a valve installed on it.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By fixing the temperature regulating mechanism inside the quenching box, this utility model avoids damage to the connecting pipes caused by the temperature regulating mechanism's rise and fall. Furthermore, the processing table for mounting the workpiece is in a height-adjustable state, facilitating adjustment according to the processing position. This protects the device without affecting its flexibility, reducing maintenance costs. Additionally, by using a CNC-controlled positioning mechanism and quenching mechanism to change its height, the parameters of various required conditions during the quenching process become more accurate, improving the product qualification rate. Ultimately, this solves the problems of increased costs due to frequent rise and fall of the temperature regulating mechanism in traditional devices, which leads to pipe damage, and the reduced qualification rate of processed parts due to deviations easily caused by manual parameter control.

The positioning mechanism includes the second motor 8 installed on the first mounting platform, which facilitates the rotation of the second lead screw 9.

The bottom end of the second lead screw 9 is installed on the lower slide plate 21, and the second lead screw 9 is threadedly connected to the second mounting platform 10, which facilitates the installation of the pressure cylinder 11.

[0023] Working Principle: When using this utility model, first connect the power supply, then input various processing parameters into the computer via CNC, install the workpiece on the quenching drill bit 19, then the second motor 8 drives the second lead screw 9 to rotate, which in turn drives the second mounting platform 10 to rise and fall. The second mounting platform 10 drives the positioning drill bit 12 to rise and fall. When the positioning drill bit 12 abuts against the top of the workpiece, the second motor 8 stops. Then, the pressure cylinder 11 presses the workpiece down again to secure its installation. Then, the first motor 5 drives the first lead screw 6 to rotate, which, with the cooperation of the linear motor 4, drives the processing frame to rise and fall. When adjusted to the appropriate position, the heating ring 24 starts to heat the processing area. At the same time, the third motor 13 drives the first gear 15 to rotate via the rotating shaft 14. The first gear 15 drives the second gear 17 to rotate via the transmission belt 16, which in turn drives the quenching pile 18 and the quenching drill bit 19 to rotate, processing the workpiece. At the same time, the drain pipe 22 opens the corresponding outlet according to the set parameters to cool the processing area. After the object is processed, the workpiece is removed, the device is reset, and the power is turned off.
