Description

Technical Field

[0001] This utility model relates to the field of automotive exterior processing technology, and in particular to a cutting and positioning fixture for automotive exterior shell assembly parts. Background Technology

[0002] Exterior trim, commonly known as automotive exterior trim, refers to the decorative elements on the exterior of a car. Exterior trim assemblies (such as bumpers, fenders, and side panels) are key components for the appearance and function of a car. Their edge precision and installation notch dimensions directly affect the overall assembly quality and appearance consistency of the vehicle. During their processing, the semi-finished products after injection molding or stamping need to be trimmed at the edges and have notches pre-reserved through cutting processes. Since these assemblies are mostly irregular curved surface structures and are mainly made of plastics and composite materials, cutting and positioning fixtures are needed to cut and process their edges.

[0003] Existing cutting and positioning fixtures typically employ a working mode of fixed positioning blocks combined with manual clamping. For specific assembly models, positioning blocks are welded or bolted to a base to define the contour features. Positioning is achieved by the bosses or grooves of the positioning blocks aligning with the reference holes and edges of the assembly. After positioning, the operator manually clamps the assembly onto the positioning blocks using screws or quick clamps, and then starts the cutting equipment to complete the cutting along a preset path. Throughout the entire process, manual handling of the quick clamps and other fixing components is required, impacting processing efficiency and increasing labor costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a cutting and positioning fixture for automotive exterior shell assembly parts, aiming to improve the problem that the existing automotive exterior cutting process requires manual labor to repeatedly move fixed components such as quick clamps, which affects processing efficiency and increases labor costs.

[0029] 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 embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Example 1, refer to Figures 1-5 This utility model provides an embodiment of a cutting and positioning fixture for an exterior trim assembly, comprising a base 1, a mounting base 2 and a worktable 5 fixedly connected to the top of the base 1, a mounting plate 10 mounted on the top of the mounting base 2, a processing component 3 mounted on the top of the mounting plate 10, a product body 4 mounted on the outer wall of the processing component 3, a motor 7 fixedly connected to the inner wall of the worktable 5, a lead screw 8 fixedly connected to the output end of the motor 7, a sliding seat 6 threadedly connected to the outer wall of the lead screw 8, and a quick-release assembly provided at the bottom of the processing component 3. The processing component 3 includes a cutting fixture 3101. 3101 is fixedly connected to the top of the mounting plate 10. The product body 4 is installed on the outer wall of the cutting fixture 3101. Multiple laser wood boards 3102 are installed on the outer wall of the sliding seat 6. A quick clamp 3103 is installed on the top of the laser wood board 3102. The quick clamp 3103 and the outer wall of the product body 4 are slidably connected to each other. Multiple working grooves are opened on the outer wall of the sliding seat 6. The outer wall of the laser wood board 3102 is installed on the inner wall of the working groove. Multiple sliding grooves are symmetrically opened on the outer wall of the worktable 5. The outer wall of the sliding seat 6 is slidably connected to the inner wall of the sliding groove. The inner wall of the sliding seat 6 is slidably connected to the outer wall of the slide rod 9.

[0031] Specifically, the base 1 provides support for the entire processing device. A recessed mounting seat 2 at the top of the base 1 provides a mounting and snap-fit ​​position for the mounting plate 10. Replaceable processing components 3 are mounted on the top of the mounting plate 10 to process different types of products. A worktable 5 is located at the top of the base 1. A motor 7 mounted on the inner wall of the worktable 5 drives the lead screw 8 to rotate. When the lead screw 8 rotates, the sliding seat 6, threaded to its outer wall, slides along the lead screw 8. Simultaneously, the other end of the sliding seat 6 is slidably connected to the outer wall of the slide rod 9 to ensure... The sliding mechanism on both sides moves synchronously. When the sliding seat 6 moves, the laser wooden board 3102 installed in the working groove on its outer wall and the quick clamp 3103 installed on the top of the laser wooden board 3102 will move synchronously and stop when they reach the processing component 3 to fix the product body 4 placed on the cutting fixture 3101, which facilitates subsequent processing. During continuous processing, it is only necessary to control the motor 7 to start and stop to drive the sliding seat 6 and the laser wooden board 3102 and quick clamp 3103 installed on it to fix and release the product, saving manpower.

[0032] Reference Figures 8-10 The quick-release assembly includes multiple locking blocks 11, which are fixedly connected to the bottom of the mounting plate 10. The inner wall of the base 1 is slidably connected to a locking block 13 and a pull slider 15. The inner wall of the base 1 is provided with a spring 14 and a spring 2 18. The outer wall of the pull slider 15 is fixedly connected to a pull ring 16 and a limiting plate 17. The outer walls of the locking blocks 11 and the locking blocks 13 are slidably connected to each other, and the outer walls of the pull slider 15 and the locking blocks 13 are slidably connected to each other. One end of the spring 14 is fixedly connected to the outer wall of the locking blocks 13, and the other end of the spring 14 is fixedly connected to the inner wall of the base 1. One end of the spring 2 18 is fixedly connected to the outer wall of the limiting plate 17, and the other end of the spring 2 18 is fixedly connected to the inner wall of the base 1.

[0033] Specifically, in the default state, the mounting plate 10 at the bottom of the processing component 3 is engaged with the mounting hole 12 at the top of the mounting base 2 by multiple locking blocks 11. One side of the outer wall of the locking block 11 is provided with an inclined surface, and one side of the locking block 13 is also provided with an inclined surface corresponding to the inclined surface of the locking block 11. At the same time, the other side of the locking block 13 is also provided with an inclined surface that matches the outer wall of the inclined surface of the pull slider 15. When the processing component 3 needs to be removed for replacement or maintenance, the pull ring 16 needs to be pulled upward to make the pull slider 15 fixedly connected at the bottom rise together. The locking block 13 is moved horizontally by the contact between the inclined surface of the pull slider 15 and the inclined surface of the locking block 13, thereby releasing the locking. The blocking of the locking block 11 by the block 13 allows the processing component 3 and the mounting plate 10 to be disassembled. When reinstalled, the locking block 13 is moved horizontally by the contact between the inclined surface of the locking block 11 and the inclined surface of the locking block 13, and finally the outer wall of the locking block 13 forms a locking block against the outer wall of the locking block 11 to complete the fixation. The two ends of the first spring 14 are connected to the base 1 and the locking block 13 respectively, and the two ends of the second spring 18 are connected to the base 1 and the limiting plate 17 respectively. When the locking block 11 is inserted or pulled out, the stress of the first spring 14 and the second spring 18 pushes the locking block 13 and the limiting plate 17 to reset respectively, and continuously applies the locking force, thereby ensuring that the device can be reused multiple times.

[0034] Reference Figure 9 and Figure 10 The outer wall of the mounting base 2 has multiple mounting holes 12 that extend through it. The locking block 11 is engaged with the inner wall of the mounting hole 12. The inner walls of the base 1 and the mounting base 2 are interconnected. The inner wall of the base 1 has multiple limiting grooves. The outer walls of the locking block 13, the pulling slider 15 and the limiting plate 17 are all slidably connected to the inner wall of the limiting groove.

[0035] Specifically, the top outer wall of the mounting base 2 is provided with a mounting hole 12 corresponding to the shape of the locking block 11. The locking block 11 is engaged through the mounting hole 12. The inner walls of the base 1 and the mounting base 2 are connected. The locking block 13 slides in the through groove of the inner wall of the base 1 and the mounting base 2. At the same time, the limiting groove in the base 1 provides a limit to the sliding of the locking block 13, the pulling slider 15 and the limiting plate 17, so that the locking block 13, the pulling slider 15 and the limiting plate 17 always maintain a straight line when they slide against each other and will not deviate, thus making the engagement structure more stable.

[0036] Example 2, refer to Figure 6 and Figure 7This embodiment is based on the description of Embodiment 1. The processing component 3 also includes a second cutting fixture 3201, which is fixedly connected to the top of the mounting plate 10. The product body 4 is installed on the outer wall of the second cutting fixture 3201. The outer wall of the product body 4 is provided with multiple laser wood board pressure plates 3202. Both the outer walls of the second cutting fixture 3201 and the laser wood board pressure plates 3202 are provided with multiple working holes 3203.

[0037] Specifically, when different products need to be processed, the cutting fixture 3201 is used to process the products. When the cutting fixture 3201 is installed on the base 1 and the mounting base 2 through the quick disassembly and assembly components, the product body 4 is placed on top of the laser wood board pressure plate 3202. The laser wood board pressure plate 3202 is attached to both sides of the product body 4. Magnets are placed in the multiple working holes 3203 corresponding to the outer walls of the cutting fixture 3201 and the laser wood board pressure plate 3202. The magnetic attraction is used to firmly fix the laser wood board pressure plate 3202 in the middle on the cutting fixture 3201 for subsequent processing.

[0038] Working principle: When using this tooling to cut the outer shell of a vehicle, if the cutting tooling 3201 is to be used to process the product body 4, the magnet needs to be embedded in the pre-drilled working holes 3203 on the cutting tooling 3201 and the laser wood plate 3202. The product body 4 is placed on the cutting tooling according to its shape, and then the laser wood plate 3202 is pressed on. After that, the product body 4 can be processed.

[0039] If the product body 4 is to be processed using cutting fixture 3101, the product body 4 is placed on cutting fixture 3101 according to the shape of the cutting fixture. Then, the motor 7 is started, which drives the lead screw 8 to rotate. The thread drives the sliding seat 6 to slide along the direction of the lead screw 8 and the sliding rod 9 on the inner wall of the worktable 5 until it reaches the front of the product body 4 installed on cutting fixture 3101. According to the shape of the product body 4, multiple laser wooden boards 3102 are fixed in the multiple working slots opened on the sliding seat 6. Quick clamps 3103 are fixedly installed on the laser wooden boards 3102. After clamping the quick clamps 3103, the product can be processed. Finally, the installation, processing and disassembly of the product body 4 are repeated by repeatedly starting the motor 7 to drive the quick clamps 3103 to slide back and forth.

[0040] By default, both cutting fixture 1 3101 and cutting fixture 2 3201 are mounted on base 1 and mounting seat 2 via mounting plate 10 at the bottom. When cutting fixture 1 3101 and cutting fixture 2 3201 need to be replaced or maintained, pull ring 16 needs to be pulled upwards to drive sliding block 15 and limit plate 17 to slide upwards simultaneously. While limit plate 17 slides upwards, spring 2 18 is compressed. During the upward movement of sliding block 15, the inclined surface of its outer wall will abut against the inclined surface of the outer wall of snap-fit ​​block 13, thereby driving snap-fit ​​block 13 to slide laterally and compress spring 1 14. Finally, snap-fit ​​block 13 disengages from snap-fit ​​block 11. At this time, snap-fit ​​block 11 can be pulled out from the mounting hole 12 on mounting seat 2, thereby removing mounting plate 10 from base 1 and mounting seat 2.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
