Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, specifically to a magnetic laser cutting fixture. Background Technology

[0002] The car bumper cutting fixture is a piece of equipment used for processing car bumpers. It uses laser cutting technology combined with a precise positioning system to improve the positioning accuracy and efficiency of bumper processing.

[0003] Currently, when laser cutting car bumpers, a dual positioning method using profile and cylinder clamps is typically employed. During mass production, scrap material can obstruct the clamp path, causing the clamps to fail to open and resulting in a collision. Furthermore, each cylinder clamp requires individual signal retrieval and the setting of avoidance actions based on the cutting path to avoid the cutting edge, cutting hole, and idle travel. Moreover, the opening and closing of the cylinder clamps can cause a certain degree of vibration in the parts, leading to part shaking and affecting the cutting quality, all of which can result in prolonged equipment downtime.

[0004] Based on this, this utility model designs a magnetic laser cutting fixture to solve the above problems. Utility Model Content

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0043] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0044] In some embodiments, please refer to the accompanying drawings. Figures 1-6 A magnetic laser cutting fixture includes a base frame 1, a cutting head 2, a multi-point adjustable support mechanism 3, and a positioning mechanism 4; the upper end of the base frame 1 is equipped with a multi-point adjustable support mechanism 3 for supporting and fixing the workpiece body 5.

[0045] The upper end of the cutting head 2 is fixedly connected to the movable end of the cutting machine;

[0046] like Figure 1 As shown, the multi-point adjustable support mechanism 3 includes a first support part, a second support part, a third support part, and a magnetic adsorption cylinder 35.

[0047] The first support section, the second support section, and the third support section have the same structure and function, only their installation positions are different; the first support section, the second support section, and the third support section are installed at the upper end of the base frame 1 from left to right.

[0048] The first support part, the second support part, and the third support part are all composed of a support and fixing component and a multi-degree-of-freedom adjustment component 34 for adjusting the spatial position of the magnetic adsorption cylinder 35.

[0049] A magnetic adsorption cylinder 35 is installed on the multi-degree-of-freedom adjustment assembly 34 of the first support part, the second support part, and the third support part.

[0050] The magnetic adsorption cylinder 35 adopts mature technology in the industry; for example, the magnetic adsorption cylinder of model MHM-X6400 produced by SMC.

[0051] The third support is also equipped with a positioning mechanism 4 for positioning and placing the workpiece body 5.

[0052] In this invention, the workpiece body 5 is first positioned by the positioning mechanism 4, placing it above the first support, second support, and third support. Then, the support and fixing components of the first, second, and third support sequentially support and fix the lower left, lower middle, and lower right sides of the workpiece body 5. Next, the orientation of the magnetic adsorption cylinder 35 is adjusted by the multi-degree-of-freedom adjustment component 34, aligning the movable end of the magnetic adsorption cylinder 35 with the lower end of the workpiece body 5. Then, the magnetic adsorption cylinder 35 operates to adsorb and fix the lower end of the workpiece body 5. Finally, the cutting machine operates, driving the cutting head 2 to move, thus cutting the workpiece body 5. The upper end is used for cutting operations. Through the cooperation of the positioning mechanism 4 and the magnetic adsorption cylinder 35, the interference of waste material is avoided, which may cause the cutting head 2 to collide with the clamping mechanism during operation, thus reducing the equipment failure rate. Furthermore, since the magnetic adsorption cylinder 35 only fixes the workpiece body 5 from the lower end, it will not interfere with the cutting trajectory of the cutting head 2, eliminating the need for avoidance adjustments, shortening the adjustment time, and increasing production time. Moreover, after the workpiece body 5 is placed, it will remain in an adsorbed state throughout the entire processing process and will only be released after the workpiece body 5 is processed, so that the workpiece body 5 will not shake during the entire processing process, thus improving the cutting quality.

[0053] like Figures 1-3 As shown, the support and fixing assembly includes a fixed horizontal plate 31, a buffer support block 32, a contour support block 33, and a support vertical plate 36;

[0054] A fixed horizontal plate 31 for the first support is provided and is fixedly installed on the upper left side of the base frame 1;

[0055] The second support has two fixed horizontal plates 31, which are fixedly installed at the upper middle part of the base frame 1;

[0058] A buffer support block 32 and a contour support block 33 are fixedly installed on the upper end of the support plate 36;

[0059] Furthermore, the multi-degree-of-freedom adjustment component 34 of the first support is installed at the upper middle part of the support plate 36;

[0060] The multi-degree-of-freedom adjustment component 34 of the second support is installed at the upper end of the left support plate 36 of the second support;

[0061] The multi-degree-of-freedom adjustment component 34 of the third support is installed at the upper end of the left support plate 36 of the third support;

[0062] like Figures 1-4 As shown, the multi-degree-of-freedom adjustment assembly 34 includes a first L-shaped plate 341, a second L-shaped plate 342, a fixed mounting cylinder 343, a first pad 344, a second pad 345, and a third pad 346; the lower end of the first L-shaped plate 341 is fixedly connected to the upper end of the supporting upright plate 36 by bolts with the first pad 344.

[0063] A second pad 345 is fixedly installed between the right end of the second L-shaped plate 342 and the left end of the first L-shaped plate 341 by bolts.

[0064] A pad 346 is fixedly installed between the rear end of the second L-shaped plate 342 and the front end of the fixed installation cylinder 343 by bolts.

[0065] The fixed installation cylinder 343 is fixedly connected to the magnetic adsorption cylinder 35;

[0066] like Figure 5 As shown, the positioning mechanism 4 includes a positioning seat 41 and a pin 43; the positioning seat 41 is fixedly installed on the upper right side of the right support plate 36 of the third support part; the upper end of the positioning seat 41 and the right side of the workpiece body 5 are both provided with pin holes 42 for insertion into the pin 43.

[0067] In this utility model, the pin hole 42 on the right side of the workpiece body 5 is first aligned with the pin hole 42 on the upper end of the positioning seat 41. Then, the pin 43 is inserted into the pin hole 42 to achieve the initial positioning of the workpiece body 5. At this time, the upper ends of the buffer support block 32 and the contour support block 33 of the first support part are aligned with the lower left side of the workpiece body 5; the buffer support block 32 and the contour support block 33 of the second support part are aligned with the lower middle part of the workpiece body 5; and the buffer support block 32 and the contour support block 33 of the third support part are aligned with the lower right side of the workpiece body 5 to achieve the support and fixation of the workpiece body 5.

[0068] Then, by changing the thickness of the pad 344, the height of the first L-shaped plate 341 in the vertical direction can be changed, thereby changing the height of the magnetic adsorption cylinder 35 in the vertical direction.

[0069] By changing the thickness of the second pad 345, the spatial position of the second L-shaped plate 342 in the horizontal left and right directions can be changed, thereby changing the spatial position of the magnetic adsorption cylinder 35 in the horizontal left and right directions.

[0070] By changing the thickness of the pad 346, the spatial position of the fixed installation cylinder 343 in the horizontal front-back direction can be changed, thereby changing the spatial position of the magnetic adsorption cylinder 35 in the horizontal front-back direction.

[0071] Using the above method, the moving end of the magnetic adsorption cylinder 35 is aligned with the lower end of the workpiece body 5; then the magnetic adsorption cylinder 35 works to adsorb and fix the lower end of the workpiece body 5; then the cutting machine works to drive the cutting head 2 to move, and the upper end of the workpiece body 5 can be cut.

[0072] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
