Description

Technical Field

[0001] The utility model relates to the technical field of automobile exterior decoration carving, in particular to a positioning device for automobile exterior decoration carving. Background Technique

[0002] In the automobile manufacturing industry, exterior decoration carving is one of the key steps to improve the appearance quality of automobiles. However, traditional positioning devices for automobile exterior decoration carving face many challenges during die change operations, which directly affect production efficiency and product quality.

[0003] Traditional positioning devices for automobile exterior decoration carving often adopt fixed support mechanisms, positioning pins and lamp inspection machines. Among them, the support mechanism usually uses multiple conventional support columns. These support columns have obvious limitations in design and use. They cannot be precisely matched and supported according to the specific shape of automobile parts. During the carving process, the exterior decoration parts may shift, which not only affects the carving accuracy and product quality, but may also cause damage to automobile parts, further increasing the production cost of enterprises. Moreover, during the die change operation, since the support columns are fixed, whenever different automobile exterior decoration parts need to be replaced for carving, in order to adapt to the appropriate support points of different automobile exterior decoration parts, all support columns need to be removed and installed in a cumbersome manner. These operations are not only time-consuming and laborious, but also require operators to have high professional skills and rich experience. In addition, due to the limitations of the positioning device design, the process of adjusting the positioning device and fixing parts is also extremely complex, further reducing production efficiency. This cumbersome die change process not only leads to an extended production cycle, but also increases the labor intensity of operators and the risk of operation errors. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a positioning device for automobile exterior decoration carving, which can solve the problems of easy displacement and low die change efficiency existing in the existing positioning devices for automobile exterior decoration carving.

[0005] To solve the above problems, the technical solution adopted by the utility model is: this positioning device for automobile exterior decoration carving includes a fixed base installed on the workbench surface of the carving machine. The fixed base is provided with a fork insertion opening for the forklift arm to insert; a template is placed on the fixed base. The template is provided with a forklift arm docking port corresponding to the fork insertion opening. The template is also provided with die change fixing holes, and the die change positioning holes are matched with the fixing pins on the forklift arm; a positioning element for positioning the template is installed on the fixed base. An imitation support frame and a plurality of pneumatic pressing mechanisms are installed on the template, and the pneumatic pressing mechanisms press the automobile exterior decoration parts on the imitation support frame.

[0006] In the technical solution of the above positioning device for automotive exterior decoration engraving, a more specific technical solution may further be: The positioning elements include a corner limit folding plate and a positioning pin vertically installed on the fixed base. The corner limit folding plate abuts against the two outer end corners of the template, and the positioning pin is inserted into the insertion positioning hole of the template.

[0007] In some possible implementation schemes, the pneumatic pressing mechanism includes a bracket, a flipping cylinder, a support arm, and a profiling pressing block. The flipping cylinder is installed on the bracket. The support arm is rotatably connected to the bracket and the extending end of the flipping cylinder respectively. A profiling pressing block is installed at the bottom of the other end of the support arm, and the profiling pressing block is connected to the support arm through an adjusting bolt.

[0008] In some possible implementation schemes, a pneumatic socket strip is installed on the template and the workbench surface. The pneumatic socket strip includes a first socket plate, a second socket plate, a male head, a female head, a cylinder mounting seat, a moving seat, a guide rail, and a pushing cylinder. The first socket plate is vertically installed on the template. The cylinder mounting seat and the guide rail are fixed on the workbench surface. The extending end of the pushing cylinder is connected to the moving seat and pushes the moving seat to move back and forth on the guide rail. The male head and the female head that are inserted into each other are respectively arranged on the opposite surfaces of the first socket plate and the second socket plate.

[0009] In some possible implementation schemes, a lamp inspection machine for detecting the quality of the engraved pattern of the automotive exterior part is installed on the template.

[0010] In some possible implementation schemes, the outer corner of the forklift arm docking port is an arc angle.

[0011] In some possible implementation schemes, two die-changing fixing holes close to the forklift arm docking port are symmetrically arranged on the template.

[0012] In some possible implementation schemes, two insertion positioning holes are symmetrically arranged on the template.

[0013] In some possible implementation schemes, protective sleeves are installed in both the insertion positioning holes and the die-changing fixing holes.

[0014] In some possible implementation schemes, the fixed base includes a cross beam and two beam frames symmetrically installed on one side of the cross beam. A support plate is provided inside the beam frames, and a reinforcing beam with one end connected to the cross beam is centrally arranged between the two beam frames.

[0015] Due to the adoption of the above technical solution, the present utility model has the following beneficial effects compared with the prior art:

[0016] 1. Install a fixed base with a forklift arm insertable on the workbench surface of the automotive exterior engraving machine, and cooperate with a template for installing an adapted automotive exterior tooling component inserted on the fixed base. The template and the engraving tooling component installed on the template can be quickly lifted by a forklift for replacement, significantly simplifying the die-changing process and greatly improving the die-changing efficiency. The profiling support frame installed on the template can be customized according to the contour of the automotive exterior part to provide precise support points, ensuring stability and accuracy during the engraving process and also helping to prevent deformation or damage to the automotive exterior part during the engraving process. The multiple pneumatic clamping mechanisms installed on the template can quickly clamp the automotive exterior part onto the profiling support frame, ensuring stability and accuracy during the engraving process.

[0017] 2. The positioning elements are set as positioning pins and corner limit folding plates installed on the fixed base, effectively restricting the movement of the template in the horizontal direction. At the same time, the positioning pins are inserted into the template, further enhancing the stability of the template in the vertical direction. The dual positioning mechanism significantly reduces the risk of the template shifting during the engraving process.

[0018] 3. Driven by a flipping cylinder, the support arm can quickly flip, driving the profiling pressing block to quickly clamp or release the automotive exterior part, significantly improving the efficiency of the clamping operation, reducing the time and labor intensity of manual operation; the clamping is reliable and will not fail due to vibration or impact; since the profiling pressing block and the support arm are connected by an adjusting bolt, fine-tuning can be performed according to automotive exterior parts of different shapes and sizes to ensure that the profiling pressing block can accurately and stably clamp the workpiece. This adjustment structure enables the same set of clamping mechanism to be applied to multiple different production scenarios, improving the utilization rate of the equipment.

[0019] 4. An air-powered plug-in row is set on the template, which can achieve precise and quick insertion and is convenient to operate.

[0020] 5. The outer corner of the forklift arm docking port is an arc angle, which is conducive to the forklift arm quickly and smoothly guiding into the docking position.

[0021] 6. Since the die-changing fixing holes are symmetrically arranged near the forklift arm docking port, the forklift arm can quickly and accurately find the fixed position when changing the die, reducing the adjustment time; the symmetrically designed fixing holes make the forklift arm more stable during the docking process, reducing the operation difficulty, thereby improving the overall efficiency of die-changing.

[0022] 7. Protection sleeves are set on the positioning holes and fixing holes on the template to avoid direct contact between these holes and the corresponding inserted components, prevent wear and deformation of the holes, and improve the assembly accuracy and stability.

[0023] 8. The structural design of the fixed base is reasonable. It can bear a larger load while maintaining a relatively light weight. The symmetrical beam frame design enables the fixed base to maintain a good balance when subjected to force, avoiding local deformation or damage caused by uneven force. The combined effect of the strengthening beam and the support plate can also reduce the vibration of the fixed base when subjected to external force, thereby improving the stability and working accuracy of the equipment.

[0030] The utility model is further described in detail below in conjunction with the accompanying drawings:

[0031] Figure 1 The automobile exterior engraving tooling shown mainly includes a fixed base 1, a template 2, a contour support frame 3, a pneumatic clamping mechanism 4, and an air suction machine mounting frame 5, wherein the fixed base 1 is firmly mounted on the work surface of the engraving machine by a plurality of anchor bolts, the template 2 is inserted on the fixed base 1, and the contour support frame 3, the pneumatic clamping mechanism 4, and the air suction machine mounting frame 5 are all installed and fixed on the template 2.

[0032] like Figure 1 and Figure 2As shown, the fixed base 1 serves as the basic support structure of the entire tooling. Its design fully considers stability, load-bearing capacity, and convenience. The fixed base 1 in this embodiment is a symmetric structure, mainly composed of a cross beam 6, a beam frame, a strengthening beam 10, and a positioning plate 14. Bolting mounting plates are provided at both ends of the cross beam 6, on the outer side surfaces of the beam frame, and at the outer ends of the strengthening beam 10. The fixed base 1 is firmly mounted on the workbench surface of the engraving machine through anchor bolts inserted through these bolting mounting plates to ensure no displacement during the engraving process. The cross beam 6 spans across the entire base and is fixedly connected to other components, providing a stable support platform for the upper template 2. Two beam frames are symmetrically mounted on one side of the cross beam 6. The beam frame is a rectangular frame body, and a support plate 8 connecting the two longitudinal beams 7 of the frame body is provided at the middle position inside the frame to enhance the overall stability and load-bearing capacity of the structure. To further improve the load-bearing capacity, a strengthening beam 10 is centrally provided at the middle position on the side surface of the cross beam 6 between the two beam frames. One end of the strengthening beam 10 is closely connected to the cross beam 6, effectively dispersing and bearing the weights from the template 2, the tooling components, and the automotive exterior parts. The length of the strengthening beam 10 is less than that of the beam frame, and the space between the two beam frames and the outer ends of the strengthening beam 10 forms a fork-in opening 11 for the forklift arm to be inserted between the beam frame and the strengthening beam 10. To reduce the friction and impact between the forklift arm and the fixed base 1, a plurality of rollers 12 are evenly distributed on the opposite side surfaces of the longitudinal beams 7 on the inner sides of the two beam frames. A positioning pin 9 and a corner limit folding plate 13 are vertically mounted on the fixed base 1. The corner limit folding plate 13 closely abuts against the two outer end corners of the template 2 to limit the horizontal movement of the template 2. The positioning pin 9 is precisely inserted into the template 2 to achieve vertical positioning. The two together constitute a dual positioning mechanism to ensure engraving accuracy.

[0033] As Figure 1 and Figure 3As shown, the template 2 adopts a pluggable design, which is convenient for quick replacement to adapt to different models of automotive exterior parts, simplifies the die-changing process, reduces the adjustment time, and improves the overall efficiency of die-changing. The template 2 is provided with a forklift arm docking port 15 corresponding to the fork insertion opening 11 of the fixed base 1, as well as two insertion positioning holes 17 and two die-changing fixing holes 16. The design of the forklift arm docking port 15 facilitates the quick docking of the forklift arm. The outer corner of the forklift arm docking port 15 is designed as a rounded corner, which can quickly guide to the docking position and reduce the friction and impact during docking. The two symmetrically installed insertion positioning holes 17 are used to install the positioning pins 9 to achieve precise positioning of the template 2. The die-changing fixing holes 16 are matched with the fixing pins on the forklift arm. They are symmetrically arranged near the forklift arm docking port 15, enabling the forklift arm to quickly and accurately find the fixing position and lock during template replacement, thereby improving the stability of the template 2 during the process of being lifted by the forklift. Protective sleeves are installed in these holes to prevent wear and deformation. Multiple profiling support frames 3 and multiple pneumatic clamping mechanisms 4 are also installed on the template 2. The profiling support frames 3 are customized according to the shape of the automotive exterior parts to provide precise support for the automotive exterior parts. The pneumatic clamping mechanism 4 fastens the automotive exterior parts during engraving to prevent the automotive exterior parts from shifting.

[0034] As Figure 1 and Figure 4 shown, the pneumatic clamping mechanism 4 mainly includes a bracket 18, a flipping cylinder 19, a support arm 20, and a profiling pressing block 21. Among them, the flipping cylinder 19 is installed on the bracket 18. The support arm 20 is rotatably connected to the bracket 18 and the extending end of the flipping cylinder 19 respectively. The bottom of the other end of the support arm 20 is installed with a profiling pressing block 21. The profiling pressing block 21 is connected to the support arm 20 through an adjusting bolt, which is convenient for fine-tuning according to automotive exterior parts of different shapes and sizes to ensure that the profiling pressing block 21 can accurately and stably press the workpiece. This adjustment structure enables the same set of clamping mechanism to be applied to a variety of different production scenarios, improving the utilization rate and flexibility of the equipment. During operation, the support arm 20 is driven to flip by the flipping cylinder 19, driving the profiling pressing block 21 to quickly press or release the workpiece to ensure stability during the engraving process.

[0035] To further improve the operation convenience and product quality control level of the automotive exterior engraving tooling, a pneumatic plug board 22, a lamp inspection machine, and a suction machine mounting bracket 5 are also integrated on the template 2. The pneumatic plug board 22 adopts a quick-insert design, which is convenient for the quick connection and disconnection of the power supply, reducing the operation time and complexity. As Figure 5As shown, the pneumatic plug board 22 is installed on the template 2 and the workbench surface of the engraving machine. The pneumatic plug board 22 includes a first plug board 27, a second plug board 28, a male head, a female head, a cylinder mounting seat 24, a moving seat 25, a guide rail 29, and a pushing cylinder 23. The first plug board 27 is erected and installed on the template 2. The cylinder mounting seat 24 and the guide rail 26 are fixed on the workbench surface. The extending end of the pushing cylinder 23 is connected to the moving seat 25 and pushes the moving seat 25 to move back and forth on the guide rail 26. The opposite surfaces of the first plug board 27 and the second plug board 28 are respectively provided with a male head and a female head that are inserted into each other. At the same time, the pneumatic plug board 22 is respectively connected to an external power supply and the mechanisms on the template 2 that require power through cables to provide them with stable and reliable power supply. Preferably, a reinforcing plate 29 connected to the second plug board 28 is further provided on the moving seat 25. A cylindrical guiding component that is inserted into each other is provided on the opposite surfaces of the first plug board 27 and the second plug board 28. Limit switches can be provided on the workbench surface and the moving seat 25. The lamp inspection machine is used to detect the quality of the engraved pattern of the automotive exterior parts. Through high-precision lighting and imaging technologies, the engraved pattern is carefully observed and analyzed to ensure that the product quality meets the standard requirements. This design not only improves the stability of the product quality but also enhances the intelligent level of the tooling. On the other side of the template 2, an air suction machine mounting bracket 5 is installed and fixed by being precisely mounted on the positioning plate 14 of the cross beam 6. See Figure 2 , to ensure that the air suction machine installed on it can effectively suck away the dust and debris generated during the engraving process and keep the working area clean.

[0036] Before the operation, according to the model of the automotive exterior part to be engraved, the template 2 and the corresponding tooling components are pre-installed to obtain a module. First, according to the shape of the automotive exterior part, the customized profiling support frame 3 is installed on the template 2 to provide precise support for the workpiece. According to the specific shape and size of the workpiece, the position and force of the profiling pressing block 21 are adjusted by adjusting bolts to ensure that the profiling pressing block 21 can firmly press the workpiece. Start the flipping cylinder 19 and check whether the flipping actions of the support arm 20 and the profiling pressing block 21 are smooth without jamming. Start the pushing cylinder 23 of the pneumatic plug board 22 to quickly dock the male head and the female head to ensure stable power supply. According to the position of the engraved pattern, the lamp inspection machine is installed at the corresponding position on the template 2. Use a forklift to quickly dock the module to the fixed base 1 through the forklift arm docking port 15 to ensure that the fixing pins on the forklift arm accurately match and lock with the die change fixing holes 16 on the template 2. Use the positioning pin 9 to precisely insert into the insertion positioning hole 17 in the template 2, and at the same time adjust the corner limit folding plate 13 to closely abut against the outer corner of the template 2 to achieve double positioning of the template 2 in the horizontal and vertical directions and ensure the engraving accuracy.

[0037] When performing the engraving function, place the automotive exterior part to be engraved on the profiling support frame 3 to ensure that the workpiece is stable and does not shake. Start the pneumatic clamping mechanism 4. The flipping cylinder 19 drives the support arm 20 to flip, and the profiling pressing block 21 quickly presses the workpiece to prevent displacement during the engraving process. After confirming that everything is ready, start the engraving machine to start the engraving operation. At the same time, turn on the lamp inspection machine to monitor the engraving process in real time to ensure the quality of the engraved pattern. During the engraving process, the suction machine keeps working, and the suction machine on the suction machine mounting bracket 5 effectively sucks away the generated dust and debris to keep the working area clean. After engraving is completed, turn off the engraving machine and the pneumatic system, and use the lamp inspection machine to carefully check the engraved pattern to ensure that the pattern is clear, flawless, and meets the quality standards. If it is necessary to replace the module to adapt to different models of automotive exterior parts, use a forklift to lift and replace the module from the fixed base 1.

[0038] The above embodiments only show the preferred specific implementation manners of the present utility model. Although the description is relatively specific and detailed, it should not be construed as a limitation on the scope of patent protection of the present utility model. It should be clear that for those of ordinary skill in the art, without departing from the core concept and basic principles of the present utility model, various deformations and improvements can be made to the present utility model. These deformations and improvements should all be regarded as belonging to the protection scope of the present utility model.
