Description

Technical Field

[0001] This utility model relates to the technical field of flywheel production, specifically to an automatic laser marking machine for flywheels. Background Technology

[0002] In the automotive engine manufacturing industry, the flywheel, as a key component for starting and power transmission, needs to be laser-marked on its surface to engrave traceability information such as part number, batch code, and QR code.

[0003] Traditional marking methods often employ manual placement combined with a fixed laser head, which suffers from low positioning accuracy, difficulty in changing models, and inability to adapt to different flywheel specifications. While some automated equipment incorporates clamping mechanisms, these are mostly rigid positioning methods, making it difficult to accommodate flywheels with various center hole distances and outer diameters. Furthermore, the lack of horizontal support after clamping makes them prone to eccentricity due to their own weight, affecting the consistency of the marking position.

[0004] Furthermore, in existing equipment, the rotary drive and marking head movement are often controlled independently, resulting in poor coordination and making it difficult to achieve high-precision circular marking. Especially for finished flywheels that have already undergone precision machining, slippage or surface indentations during the clamping process will directly affect the product's appearance and assembly quality.

[0005] Therefore, there is an urgent need for a flywheel automatic laser marking machine with a reasonable structure, precise positioning, strong versatility, and the ability to protect the surface of workpieces, in order to meet the comprehensive requirements of modern intelligent manufacturing for efficiency, precision, and flexibility. Utility Model Content

[0006] The purpose of this invention is to provide an automatic laser marking machine with a flywheel to solve the above-mentioned defects caused by the prior art.

[0007] A flywheel automatic laser marking machine, comprising: The positioning mechanism includes a mounting platform, a bearing seat, and a mounting shaft. The mounting shaft is rotatably connected to the center position of the mounting platform via the bearing seat. A mounting plate is coaxially connected to the top of the mounting shaft, and two positioning pins are provided on the top of the mounting plate. Multiple rotating mechanisms are evenly arranged around the mounting shaft in the circumferential direction. Each rotating mechanism includes a mounting frame, a double-rod cylinder, a mounting plate, and a motor. The double-rod cylinder is horizontally mounted inward on the upper side of the mounting platform through the mounting frame. The motor is vertically mounted upward on the end of the piston rod of the double-rod cylinder through the L-shaped mounting plate. A rotating wheel is fixedly connected to its output shaft. The marking mechanism, located behind the mounting shaft, includes a second mounting frame, a second double-rod cylinder, a second mounting plate, and a laser marking head. The second double-rod cylinder is horizontally mounted forward on the upper side of the mounting platform via the second mounting frame, and the laser marking head is vertically mounted downward on the end of the piston rod of the second double-rod cylinder via the L-shaped second mounting plate.

[0008] Preferably, the mounting plate has an I-shaped mounting groove in the middle, and two mounting blocks are slidably fitted in the mounting groove. A mounting ring is fixedly connected to the outer circumference of the mounting plate. Two coaxially distributed threaded rods are threadedly connected to the mounting ring along the radial direction. The inner ends of the two threaded rods are respectively threaded to the corresponding mounting blocks. Two locating pins are respectively vertically fixed to the corresponding mounting blocks.

[0009] Preferably, the mounting platform is provided with I-shaped positioning frames evenly around the mounting shaft, and the upper surface of the positioning frames is flush with the lower rim of the rotating wheel.

[0010] Preferably, a guide post is vertically connected to the lower part of the mounting plate, and the guide post is slidably engaged with the mounting frame via a guide sleeve.

[0011] Preferably, an L-shaped fixing plate is provided below the mounting frame one, the fixing plate is fixedly connected to the mounting platform, and a threaded rod two is rotatably connected to its upper part, the inner end of the threaded rod two being threadedly connected to the mounting frame one.

[0012] Preferably, a friction sleeve is fitted on the outer circumferential surface of the rotating wheel.

[0013] Compared with the prior art, the present invention has the following advantages: 1. High-precision positioning and adaptive adjustment: Through the adjustable spacing positioning pins and radial fine-tuning rotary mechanism, it can quickly adapt to flywheels with different center hole distances and outer diameters without changing tooling, significantly improving the equipment's versatility and changeover efficiency.

[0014] 2. Stable clamping and damage prevention design: The rotating wheel is equipped with a high-friction elastic friction sleeve, which can reliably drive the flywheel to rotate at a uniform speed and avoid scratching the machined surface; the guide post-guide sleeve guiding structure ensures that the clamping action is smooth and without deviation.

[0015] 3. Horizontal support and anti-eccentricity protection: The positioning frame provides a support reference that is coplanar with the lower rim of the rotating wheel, effectively preventing the flywheel from sagging due to its own weight, ensuring that the axis is horizontal in the clamping state, and improving the repeatability accuracy of the marking position.

[0016] 4. Safe, efficient and automated operation: The marking head is driven by a cylinder to feed laterally, achieving non-contact and precise approach and avoidance.

Detailed Implementation

[0027] 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.

[0028] like Figures 1 to 8 As shown, a flywheel automatic laser marking machine includes: The positioning mechanism 10 includes a mounting platform 101, a bearing seat 102, and a mounting shaft 103. The mounting shaft 103 is rotatably connected to the center of the mounting platform 101 via the bearing seat 102. The top end of the mounting shaft 103 is coaxially connected to a mounting plate 104, and the top of the mounting plate 104 is provided with two positioning pins 106. The positioning mechanism 10 achieves rapid and accurate positioning of the flywheel 401 through the mounting plate 104 and the positioning pins 106, ensuring consistent marking positions. The mounting shaft 103 can be rotated manually or electrically, facilitating multi-angle marking or alignment calibration.

[0029] Multiple rotating mechanisms 20 are evenly arranged around the mounting shaft 103 in the circumferential direction. Each rotating mechanism 20 includes a mounting frame 201, a double-rod cylinder 202, a mounting plate 203, and a motor 204. The double-rod cylinder 202 is horizontally mounted inward on the upper side of the mounting platform 101 through the mounting frame 201. The motor 204 is vertically mounted upward on the end of the piston rod of the double-rod cylinder 202 through the L-shaped mounting plate 203. A rotating wheel 205 is fixedly connected to its output shaft. The rotating mechanism 20 pushes the rotating wheel 205 to radially clamp the outer circle of the flywheel 401 through the double-rod cylinder 202, and the motor 204 drives the flywheel 401 to rotate at a uniform speed, realizing continuous or indexed marking in the circumferential direction, which is suitable for complex marking needs such as ring QR codes and serial numbers.

[0030] The marking mechanism 30, located behind the mounting shaft 103, includes a second mounting frame 301, a second double-rod cylinder 302, a second mounting plate 303, and a laser marking head 304. The second double-rod cylinder 302 is horizontally mounted forward on the upper side of the mounting platform 101 via the second mounting frame 301. The laser marking head 304 is vertically mounted downward on the end of the piston rod of the second double-rod cylinder 302 via the L-shaped mounting plate 303. The marking mechanism 30 uses the second double-rod cylinder 302 to drive the laser marking head 304 laterally towards / away from the surface of the flywheel 401, achieving non-contact precise displacement and safe avoidance, preventing interference with the loading and unloading of the flywheel 401, and improving the automation and safety of the equipment.

[0031] In this embodiment, the mounting plate 104 has an I-shaped mounting groove 104a in the middle, and two mounting blocks 105 slide within the mounting groove 104a. A mounting ring 107 is fixedly connected to the outer circumference of the mounting plate 104, and two coaxially distributed threaded rods 108 are radially threaded onto the mounting ring 107. The inner ends of the two threaded rods 108 are respectively threaded to the corresponding mounting blocks 105, and two locating pins 106 are vertically fixed to the corresponding mounting blocks 105. By rotating the threaded rods 108, the distance between the two locating pins 106 can be adjusted synchronously, thereby quickly adapting to flywheels 401 with different center mounting hole distances without the need to change special tooling, significantly improving the equipment's versatility and changeover efficiency.

[0032] In this embodiment, the mounting platform 101 is uniformly provided with I-shaped positioning frames 109 around the mounting shaft 103. The upper surface of the positioning frame 109 is flush with the lower rim of the rotating wheel 205. The positioning frame 109 provides a horizontal support reference surface for the flywheel 401, preventing the flywheel 401 from sagging due to its own weight and causing clamping eccentricity; its upper surface is coplanar with the lower rim of the rotating wheel 205, ensuring that the flywheel 401 remains horizontal in the clamped state and improving marking accuracy.

[0033] In this embodiment, a guide post 207 is vertically connected to the lower part of the mounting plate 203. The guide post 207 is slidably engaged with the mounting frame 201 via a guide sleeve 208. The guide post 207 and the guide sleeve 208 form a guide pair, effectively constraining the movement trajectory of the motor 204 and the rotating wheel 205, preventing wobbling or deflection when the double-rod cylinder 202 operates, and improving clamping stability and repeatability.

[0034] In this embodiment, an L-shaped fixing plate 209 is provided below the mounting frame 201. The fixing plate 209 is fixedly connected to the mounting platform 101, and a threaded rod 210 is rotatably connected to its upper part. The inner end of the threaded rod 210 is threadedly connected to the mounting frame 201. By rotating the threaded rod 210, the radial position of the rotating mechanism 20 can be finely adjusted, thereby adapting to flywheels 401 with different outer diameters and expanding the applicability of the equipment; at the same time, pre-alignment can be performed during assembly or maintenance, reducing the difficulty of debugging.

[0035] In this embodiment, a friction sleeve 206 is fitted on the outer circumferential surface of the rotating wheel 205. The friction sleeve 206 is made of a high-friction coefficient elastic material (such as polyurethane) to enhance the friction between the rotating wheel 205 and the outer circle of the flywheel 401, prevent slippage, and buffer the clamping impact to avoid damage to the surface of the flywheel 401. It is especially suitable for finished flywheels that have been precision machined or coated.

[0036] The working process of a flywheel automatic laser marking machine is as follows: During operation, the flywheel 401 to be marked is placed on the mounting plate 104 of the positioning mechanism 10, and two positioning pins 106 are inserted into the two central holes to achieve initial positioning; at the same time, the bottom of the flywheel 401 is supported by the positioning brackets 109 around it to keep it horizontal.

[0037] Subsequently, the double-rod cylinder 202 of each rotating mechanism 20 is activated, pushing the rotating wheel 205 to radially clamp the outer circle of the flywheel 401, and the friction sleeve 206 provides sufficient friction to prevent slippage; the guide post 207 and the guide sleeve 208 ensure that the clamping process is smooth and without shaking.

[0038] Next, the double-cylinder 302 of the marking mechanism 30 drives the laser marking head 304 to approach the surface of the flywheel 401 laterally to a set distance. The motor 205 is started, which drives the flywheel 401 to rotate at a constant speed. The laser marking head 304 emits laser light synchronously to engrave the required text, barcode or QR code on the end face or outer circle of the flywheel 401.

[0039] After marking is completed, the laser marking head 304 retracts, the rotating wheel 205 is released, and the operator removes the flywheel 401.

[0040] The entire process is fully automated, with precise positioning and no surface damage, making it suitable for large-scale flexible production.

[0041] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
