Description

Technical Field

[0001] This utility model relates to the field of laser quenching technology, specifically to a laser surface quenching treatment device. Background Technology

[0002] Laser hardening, also known as laser phase transformation hardening or laser heat treatment, is an advanced surface modification process. It uses a high-energy-density laser beam as a heat source to rapidly heat the workpiece surface, raising its temperature quickly above the phase transformation point. The material then rapidly cools through its own thermal conductivity, resulting in a high-hardness, fine-grained martensitic structure. This improves the surface hardness, wear resistance, and fatigue strength of the workpiece. Laser hardening is widely used for surface strengthening of steel and cast iron materials, especially for vulnerable parts and critical components in industries such as metallurgy, machinery, petrochemicals, and automobile manufacturing.

[0003] However, existing laser quenching equipment lacks a structure that uses a lead screw drive to move the laser, which limits the transmission accuracy. This limited transmission accuracy can lead to inaccurate positioning during the laser quenching process, affecting the uniformity and hardness of the quenched layer. Ultimately, this can result in inconsistent workpiece surface quality and even defects such as quenching cracks, making the laser quenching process less than ideal. Therefore, we propose a laser surface quenching equipment. Utility Model Content

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] To improve the effect of laser hardening, such as Figure 1-4As shown, the laser surface hardening equipment of this utility model includes a mounting base 1, a drive assembly 2, a rotating assembly 3, a slider 5, and a slide 6. The drive assembly 2 is provided on one side of the mounting base 1. The drive assembly 2 includes a stepper motor 201, a drive shaft 202, a coupling 203, a lead screw 204, and a lead block 205. The output end of the stepper motor 201 is connected to the drive shaft 202. One end of the drive shaft 202 is connected to the lead screw 204. The coupling 203 is sleeved on the periphery between the drive shaft 202 and the lead screw 204. The lead block 205 is sleeved on the periphery of the lead screw 204. A laser 8 is installed on one side of the lead block 205 by a clamp 7 and a No. 1 screw 10.

[0027] The mounting base 1 has a base 9 installed at its bottom. A rotating assembly 3 is provided on the top of the base 9 and on one side of the mounting base 1. The rotating assembly 3 includes a servo motor 301, a connecting rod 302, a support platform 304, and a clamping plate 305. The bottom of the connecting rod 302 is connected to the output end of the servo motor 301. The support platform 304 is installed on the top of the connecting rod 302. The clamping plates 305 are evenly installed on the outer side of the support platform 304. A knob bolt 4 is provided on the top of the clamping plate 305. A rubber pad 15 is connected to the bottom of the knob bolt 4.

[0028] In use, the stepper motor 201 can drive the lead screw 204 to rotate, and the coupling 203 can effectively enhance the stability and efficiency of the transmission. Thus, the lead screw 204 can drive the lead block 205 and the laser 8 on one side of the lead block 205 to move through the lead screw transmission, so as to adjust the distance between the laser 8 and the workpiece.

[0029] The servo motor 301 can drive the support platform 304 and the workpiece on top of the support platform 304 to rotate through the connecting rod 302, thereby rotating other parts of the workpiece to below the laser 8, which is beneficial for laser quenching.

[0030] Through the action of slider 5 and groove 6, both wire block 205 and laser 8 can move smoothly, which helps to improve the accuracy of transmission.

[0031] For example, such as Figure 1 , Figure 2 , Figure 4 As shown, sliders 5 are provided on both sides of the lead screw 204. One side of the slider 5 is connected to the mounting base 1. Slide grooves 6 are provided at both ends of one side of the lead screw 204, and the slider 5 is located inside the slide groove 6.

[0032] In use, the wire block 205 can drive the laser 8 to move smoothly and steadily through the slider 5 and the groove 6.

[0033] For example, such as Figure 2 As shown, both ends of the clamp 7 are provided with positioning plates 16, and the positioning plates 16 have a first bolt hole 14 inside. The thread block 205 has a second bolt hole 17 that corresponds to the first bolt hole 14 evenly opened on one side.

[0034] In use, the laser 8 can be detachably installed on one side of the wire block 205 by means of the clamp 7, positioning plate 16, bolt hole 14 and bolt hole 17.

[0035] For example, such as Figure 3 As shown, the rotating assembly 3 also includes a circular connecting plate 303 and a second screw 306. The circular connecting plate 303 is fixed to the top of the connecting rod 302. The circular connecting plate 303 is detachably connected to the support platform 304 by the second screw 306.

[0036] In use, the connecting rod 302 can transmit the driving force applied by the servo motor 301 to the support platform 304, so that the support platform 304 can rotate.

[0037] For example, such as Figure 1 , Figure 4 As shown, a fixing plate 11 is provided on the top of the mounting base 1, and the stepper motor 201 is fixed to the top of the fixing plate 11.

[0038] When in use, the fixing plate 11 can effectively enhance the stability of the stepper motor 201.

[0039] For example, such as Figure 4 As shown, a first bearing seat 12 and a second bearing seat 13 are respectively provided at the upper and lower ends of one side of the mounting base 1.

[0040] In use, one end of the lead screw 204 is connected to the output end of the stepper motor 201, and the other end of the lead screw 204 passes through the first bearing seat 12 and is located inside the second bearing seat 13.

[0041] When using this utility model, the operator places the workpiece to be laser hardened on the top of the support platform 304 in the rotating assembly 3, and the operator turns the knob bolt 4 on the clamping plate 305 to drive the knob bolt 4 to move down. The rubber pad 15 at the bottom of the knob bolt 4 can then fit against the surface of the workpiece, thereby clamping the workpiece.

[0042] Furthermore, the stepper motor 201 in the drive assembly 2 can drive the lead screw 204 to rotate, and the coupling 203 can effectively enhance the stability and efficiency of the transmission. Thus, the lead screw 204 can drive the lead block 205 and the laser 8 on one side of the lead block 205 to move through the lead screw transmission, and the distance between the laser 8 and the workpiece can be adjusted.

[0043] Furthermore, the servo motor 301 in the rotating assembly 3 can drive the support platform 304 and the workpiece on top of the support platform 304 to rotate via the connecting rod 302, thereby rotating other parts of the workpiece to below the laser 8.

[0044] Furthermore, through the action of slider 5 and slide 6, both the wire block 205 and the laser 8 can move smoothly, which helps to improve the accuracy of transmission.
