Description

Technical Field

[0001] This application relates to the field of automotive interior decoration processing technology, and more specifically, to a positioning fixture for irregularly shaped products and equipment for processing irregularly shaped products. Background Technology

[0002] Previously, car crystal ornaments were mostly used in high-end customized models. However, with the development of the automotive industry and the upgrading of civilian vehicles, they are increasingly appearing in ordinary mid-range models. Consequently, their manufacturing process has gradually shifted from customized handcrafting to mass production and application.

[0003] In the processing of crystal ornaments, printing techniques are often used to add markings or logos. Traditional mass printing processes use an ink squeegee to apply ink to the workpiece surface via a screen printing plate. This typically requires the printed side of the workpiece to face upwards, and the workpiece height needs to be as uniform and stable as possible during batch production. However, crystal ornaments are often irregularly shaped, making it difficult to align the printed side correctly. Using fully automated, flip-up positioning machines consumes excessive machine resources. For example, existing patent CN208615478U discloses a printing positioning device for automotive glass, which uses computer-controlled multi-point internal and external positioning devices to determine the printing accuracy of glass markings. However, its machine cost is too high, and it is not suitable for block-shaped crystal ornaments. Therefore, in the printing of irregularly shaped crystal decorative parts, especially when the height consistency of crystal products is poor, it is difficult to operate smoothly using existing ordinary printing methods. Utility Model Content

[0004] This application provides a positioning fixture and processing equipment for irregularly shaped products to solve the problem in the prior art that irregularly shaped products such as vehicle crystal ornaments are difficult to position for printing and processing due to their irregular size and uncontrollable height, which affects printing operations.

[0005] According to the positioning fixture for irregularly shaped products provided in this application, it includes:

[0006] A cavity assembly is provided with a placement cavity, and the front wall of the placement cavity is formed with a contoured surface that fits the irregular surface of the irregular product.

[0008] A locking assembly is provided on the cavity assembly and is used to securely lock the locating pin assembly onto the cavity assembly.

[0009] In some embodiments, a horizontal pin hole is provided on the rear cavity wall of the placement cavity, and the positioning pin assembly is slidably installed in the horizontal pin hole. The contact surface between the positioning pin assembly and the irregularly shaped product is an upwardly inclined slope.

[0010] In some embodiments, the locking component is vertically movably disposed on the cavity component, and has an angled surface facing the contour surface; the positioning pin component is provided with an inclined groove that engages with the angled surface, and the angled surface can extend into the inclined groove to press the positioning pin component, causing the positioning pin component to move toward the contour surface.

[0011] In some embodiments, the locking assembly includes a pressure plate, the middle section of which is provided with an angled clamping positioning pin assembly, and the two sides of the pressure plate are connected to the cavity assembly by adjusting bolts.

[0012] In some embodiments, the cavity assembly is further provided with a positioning block above the horizontal pin hole. The positioning block is similar in shape to the irregular product to assist in positioning the irregular product.

[0013] In some embodiments, the cavity assembly is an integrally molded structure, including a front cavity wall and a rear cavity wall that are connected only at the bottom, and the gap between the front cavity wall and the rear cavity wall forms a placement cavity.

[0014] In some embodiments, detachable positioning side plates are provided on the left and right sides of the cavity assembly, and the positioning side plates are connected to the front cavity wall and the rear cavity wall.

[0015] In some embodiments, the irregular product positioning fixture further includes a base assembly, which is provided with a fixing groove;

[0016] The bottom of the cavity assembly fits the shape of the fixing groove, and the cavity assembly is placed and installed in the fixing groove.

[0017] In some embodiments, multiple cavity assemblies are provided, and multiple cavity assemblies share a single locking assembly.

[0018] According to another aspect of this application, an irregularly shaped product processing device is provided, including: a working component and the irregularly shaped product positioning fixture as described above.

[0019] The present application provides a positioning fixture for irregularly shaped products, comprising: a cavity assembly with a placement cavity for the irregularly shaped product, the front wall of which forms a contoured surface that matches the irregularly shaped surface of the product; a positioning pin assembly disposed on the rear wall of the cavity assembly, opposite to the contoured surface, capable of suspending and pushing the irregularly shaped product against the contoured surface, thus exposing the surface to be processed vertically upwards; and a locking assembly disposed on the cavity assembly to securely lock the positioning pin assembly to the cavity assembly. This application provides a contoured surface on the cavity assembly that matches the irregularly shaped surface of the product, and a movable positioning pin assembly on the opposite side of the contoured surface. By using the positioning pin assembly to push the irregularly shaped product to suspend and adhere it to the contoured surface, the printing surface of the irregularly shaped product is controlled to be exposed vertically upwards. This overcomes the problem of irregular shapes and low height consistency affecting the positioning accuracy of the surface to be processed, and simply and cost-effectively solves the bottlenecks in printing and other processing of irregularly shaped products.

[0032] Figures 1 to 3An embodiment of the positioning tooling for irregularly shaped products of this application is illustrated schematically.

[0033] like Figures 1 to 3 As shown, this application discloses a positioning fixture for irregularly shaped products. The fixture includes: a cavity assembly 10, on which a placement cavity 11 is provided, and the front wall 12 of the placement cavity 11 forms a contoured surface 121 that matches the irregularly shaped surface of the irregularly shaped product 50; a positioning pin assembly 20, disposed on the rear wall 13 of the placement cavity 11, opposite to the contoured surface 121, capable of suspending and pushing the irregularly shaped product 50 against the contoured surface 121, so that the surface of the irregularly shaped product 50 to be processed is vertically exposed upwards; and a locking assembly 30, disposed on the cavity assembly 10, for fixing and locking the positioning pin assembly 20 onto the cavity assembly 10.

[0034] Through the above structural design, the embodiment of this application provides a contour surface 121 on the cavity assembly 10 that fits the irregular surface of the irregular product 50, and provides a movable positioning pin assembly 20 on the opposite side of the contour surface 121. The positioning pin assembly 20 pushes the irregular product 50 to be suspended and attached to the contour surface 121, thereby controlling the surface to be processed of the irregular product 50 to be exposed vertically upward. This overcomes the problem that the irregular shape and low height consistency of the irregular product 50 affect the positioning accuracy of the surface to be processed, and solves the processing bottleneck of the irregular product 50 such as printing in a simple and low-cost manner.

[0035] Among them, the irregularly shaped surface of the irregularly shaped product 50 is the main surface that reflects its characteristics. Therefore, it has stable dimensions and uses a high-precision processing method, which can serve as the positioning surface for the irregularly shaped product 50. By engaging the contoured surface 121 of the front cavity wall 12 of the cavity assembly 10 with the irregularly shaped surface, precise surface positioning of the irregularly shaped product 50 can be achieved, allowing the top surface to be processed to be vertically exposed for precise printing operations, etc. Simultaneously, since the irregularly shaped product 50 is suspended and pushed onto the contoured surface 121 by the positioning pin assembly 20, it is not affected by the height of the irregularly shaped product 50, and positioning is not affected by poor consistency in the height direction of the irregularly shaped product 50. For example, Figures 1 to 3 The irregularly shaped product 50 shown has unstable dimensions in the height direction and cannot be positioned by supporting it. However, the protruding irregularly shaped surface of the product 50 is machined using a grinding machine, resulting in relatively stable dimensions, which can be used as a positioning surface. At the same time, the front cavity wall 12 of the placement cavity 11 is machined into a partially contoured surface, which also makes it easy for operators to recognize the placement position of the irregularly shaped product 50 at a glance, simplifying operation and enhancing the identification function.

[0036] In some embodiments of this application, such as Figure 2As shown, a horizontal pin hole 131 is provided on the rear cavity wall 13 of the placement cavity 11. The positioning pin assembly 20 is slidably installed in the horizontal pin hole 131 and can slide back and forth along the horizontal pin hole 131. The contact surface between the positioning pin assembly 20 and the irregular product 50 is an upwardly inclined slope, so that the irregular product 50 can be pushed upward and forward when moving forward, so that the irregular product 50 is suspended and attached to the contour surface 121, achieving precise fixation.

[0037] In some embodiments of this application, such as Figures 1 to 3 As shown, the locking assembly 30 is vertically movable on the cavity assembly 10, and has an angled surface 311 facing the contour surface 121. The positioning pin assembly 20 has a groove 21 that mates with the angled surface 311. The angled surface 311 can extend into the groove 21 to press the positioning pin assembly 20, causing the positioning pin assembly 20 to move towards the contour surface 121. Therefore, by vertically lowering the locking assembly 30, this application can conveniently and quickly push the positioning pin assembly 20 horizontally towards the contour surface 121, thereby fixing the irregularly shaped product 50 onto the contour surface 121. It is simple to use and flexible to operate.

[0038] In some embodiments of this application, such as Figure 1 and Figure 3 As shown, the locking assembly 30 includes a pressure plate 31. The middle section of the pressure plate 31 is provided with an angled section 311 for pressing the positioning pin assembly 20. The two sides of the pressure plate 31 are connected to the cavity assembly 10 by adjusting bolts 32. By adjusting the rotation of the adjusting bolts 32, the pressure plate 31 is controlled to move downward, thereby pressing the positioning pin assembly 20 and locking the position of the positioning pin assembly 20, thus fixing the irregularly shaped product 50.

[0039] like Figure 3 As shown in this embodiment, a smooth groove 321 is provided near the nut of the adjusting bolt 32, which is engaged and fixed to the pressure plate 31. Below the groove 321 of the adjusting bolt 32 is a threaded section, which is threadedly connected to the cavity assembly 10. By rotating the adjusting bolt 32, the pressure plate 31 can be moved precisely vertically on the cavity assembly 10, thereby achieving the compression positioning of the positioning pin assembly 20.

[0040] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the cavity assembly 10 also has a positioning block 132 above the horizontal pin hole 131. The positioning block 132 is similar in shape to the irregularly shaped product 50 to assist in positioning the irregularly shaped product 50. For example, Figure 1 The positioning block 132 shown is set to have an arc surface similar to that of the irregular product 50, thereby ensuring that irregular products 50 of the same batch are in the same position when placed into the placement cavity 11, so as to improve positional consistency, ensure placement accuracy, and thus guarantee subsequent fixing accuracy.

[0041] In some embodiments of this application, such as Figure 3 As shown, the cavity assembly 10 is a one-piece molded structure, including a front cavity wall 12 and a rear cavity wall 13 connected only at the bottom. The gap between the front cavity wall 12 and the rear cavity wall 13 forms a placement cavity 11. The inner wall surface of the front cavity wall 12 forms a contoured surface 121, and the rear cavity wall 13 is hollowed out at the position opposite to the contoured surface 121 to form a horizontal pin hole 131. The cavity assembly 10 of this embodiment has a simple structure and saves materials. Since the sides and top of the placement cavity 11 are open structures, there is ample operating space, making it easier to process and repair the contoured surface 121 to obtain higher contoured positioning accuracy.

[0042] In some embodiments of this application, such as Figure 1 As shown, detachable positioning side plates 14 are respectively provided on the left and right sides of the cavity assembly 10, and the positioning side plates 14 are connected to the front cavity wall 12 and the rear cavity wall 13. The positioning side plates 14 are used to position the irregular product 50 on the left and right sides of the cavity assembly 10 after the cavity assembly 10 is processed, providing left and right position reference points.

[0043] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the irregularly shaped product positioning fixture of this application also includes a base assembly 40, which is provided with a fixing groove 41. The bottom of the cavity assembly 10 fits the shape of the fixing groove 41, and the cavity assembly 10 is placed and installed in the fixing groove 41. Through the fixing action of the base assembly 40, the cavity assembly 10 can be prevented from shaking during the printing process, thereby overcoming the influence of loading and unloading and improving the stability during printing operations. Understandably, the base assembly 40 can be fixedly installed by bolts or other fixing structures, thereby providing a stable and reliable installation platform for the cavity assembly 10. Figure 1 As shown, the bottom surface of the cavity assembly 10 is square, and the fixing groove 41 is also square. Meanwhile, the top corners of the fixing groove 41 are rounded to prevent bumps and facilitate the insertion of the cavity assembly 10. Furthermore, the cavity assembly 10 and the fixing groove 41 can also be designed with other matching shapes, which will not be elaborated here.

[0044] In some embodiments of this application, multiple cavity assemblies 10 are provided, and the multiple cavity assemblies 10 are stacked and used. For example, multiple cavity assemblies 10 are repeatedly stacked along a straight line on the base assembly 40 to achieve synchronous positioning of multiple irregularly shaped products 50. Among them, multiple cavity assemblies 10 can share a locking assembly 30, such as using an integrated pressure plate 31, so as to simultaneously position multiple irregularly shaped products 50 by a single pressure, realize batch processing, simplify operation, and improve production efficiency.

[0045] According to another aspect of this application, an irregularly shaped product processing device is provided, including: a working component and an irregularly shaped product positioning fixture as described in the above embodiment. The working component includes, but is not limited to, a printing component, an engraving component, and a polishing component.

[0046] In summary, the irregular-shaped product positioning fixture of this application includes: a cavity assembly, which has a placement cavity for the irregular-shaped product, and the front wall of the placement cavity has a contoured surface that matches the irregular-shaped surface of the product; a positioning pin assembly, which is disposed on the rear wall of the cavity assembly and is positioned opposite to the contoured surface, enabling the irregular-shaped product to be suspended and pushed against the contoured surface, so that the surface to be processed of the irregular-shaped product is vertically exposed upwards; and a locking assembly, which is disposed on the cavity assembly and is used to fix and lock the positioning pin assembly onto the cavity assembly. This application provides a contoured surface on the cavity assembly that matches the irregular-shaped surface of the product, and provides a movable positioning pin assembly on the opposite side of the contoured surface. By using the positioning pin assembly to push the irregular-shaped product to be suspended and attached to the contoured surface, the surface to be processed of the irregular-shaped product is controlled to be vertically exposed upwards. This overcomes the problem that the irregular shape and low height consistency of the irregular-shaped product affect the positioning accuracy of the surface to be processed, and solves the processing bottleneck of irregular-shaped products such as printing simply and at low cost.

[0047] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
