Technical Field

[0001] This utility model relates to the field of automobile manufacturing equipment, and in particular to a caliper structure that facilitates the replacement of date molds. Background Technology

[0002] In automotive manufacturing production lines, vehicle components (such as engine blocks, frames, and chassis) typically require imprinting of production dates, batch numbers, or unique identification codes (VIN segments) to enable quality traceability and lifecycle management. This marking is generally achieved using a specialized clamp structure with a date template, manually or via a robotic arm, pressing the template onto the component surface to create the mark.

[0003] However, existing caliper structures generally have the following problems: for example, the date template needs to be changed frequently with each production batch, and traditional calipers mostly use bolts to fasten or use embedded clips to fix the template, which is cumbersome to disassemble and assemble, highly dependent on tools, and affects the production line cycle time; the alignment of the template and the mold (the base that supports the part to be printed) depends on manual adjustment, which is prone to offset or blurring of the marking position due to accumulated errors; or the mold thickness varies greatly between different car models / parts, and existing calipers lack an adaptive adjustment mechanism, requiring multiple sets of adaptable tooling, which increases management costs;

[0004] Therefore, there is an urgent need for a date marking caliper structure that supports quick assembly and disassembly, precise positioning, and adaptability to different mold thicknesses, in order to meet the high-efficiency and high-precision production requirements of automotive production lines.

Detailed Implementation

[0032] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0033] like Figures 1 to 7 As shown in the figure, the caliper structure for easy replacement of date molds provided by this utility model embodiment includes a base plate 100 and a cover plate 200. The base plate 100 and the cover plate 200 are assembled together. During the assembly process, the base plate 100 and the cover plate 200 are connected by a positioning device 400. A limiting groove 110 is formed on the side of the base plate 100 facing the cover plate 200. The depth of the limiting groove 110 is less than the thickness of the base plate 100, the bottom area of ​​the limiting groove 110 is less than the side area of ​​the base plate 100, and the size of the limiting groove 110 is equal to the size of the mold to be pressed, so that the limiting groove 110 can limit and fix the mold.

[0034] In the above structure, the bottom of the limiting groove 110 can be set as a buffer structure. When molds of different thicknesses are placed in the limiting groove 110, the buffer structure can provide a certain depth of the limiting groove 110 for the mold. At the same time, the buffer spring on the buffer structure always abuts against the mold, so that the mold can be limited by the base plate 100 and the cover plate 200.

[0035] In this embodiment, the buffer structure mainly includes a spring. The buffer effect of the spring can support molds of different thicknesses, making it convenient to limit the mold and avoid the possibility that the assembly gap between the cover plate 200 and the base plate 100 may not be compatible when the mold thickness difference is too large, resulting in the date template 500 and the mold being too large / too small, which would affect the imprinting effect.

[0036] A first fixing groove 220 is provided on the cover plate 200 at the position corresponding to the mold. The bottom area of ​​the first fixing groove 220 is smaller than the bottom area of ​​the limiting groove 110. The first fixing groove 220 is used to install the date template 500, so that the date template 500 is limited by the first fixing groove 220. When the cover plate 200 and the base plate 100 are assembled together, the date template 500 is set exactly to correspond to the mold.

[0037] In this embodiment, the positioning device 400 includes a number of positioning pins 410. The number of positioning pins 410 is set to multiple, and the multiple positioning pins 410 are evenly distributed on the side of the base plate 100 facing the cover plate 200. In this embodiment, there are two positioning pins 410. Positioning holes 210 are opened on the cover plate 200 corresponding to the positions of the positioning pins 410. The number of positioning holes 210 is equal to the number of positioning pins 410, and the positions of the positioning holes 210 correspond to the positions of the positioning pins 410. When the positioning pins 410 are inserted into the positioning holes 210, the base plate 100 and the cover plate 200 are positioned, so that the base plate 100 and the cover plate 200 can be stably assembled together.

[0038] After the base plate 100 and cover plate 200 are assembled, the mold is limited in the limiting groove 110 and the date template 500 is limited in the first fixing groove 220. At this time, the date template 500 can be pressed onto the mold by the pressing device 300 to complete the replacement of the date template 500.

[0039] In the above structure, the pressing device 300 includes pressing rods 310. There are multiple pressing rods 310, which are evenly distributed on the cover plate 200. Each pressing rod 310 is set with a first fixing groove 220. One end of the pressing rod 310 passes through the cover plate 200 and extends into the first fixing groove 220. The end of the pressing rod 310 located in the first fixing groove 220 is provided with an abutment plate 320. The abutment plate 320 is connected to the pressing rod 310, and one side of the abutment plate 320 relative to the pressing rod 310 abuts against the date template 500. When it is necessary to press the date template 500, the pressing rod 310 can be pushed by external force, so that the pressing rod 310 drives the abutment plate 320 to move into the first fixing groove 220, thereby pressing the date template 500 onto the mold.

[0040] To facilitate the movement of the pressing rod 310, a through hole 230 is provided on the cover plate 200 corresponding to the position of the pressing rod 310. The pressing rod 310 is located in the through hole 230 and can move linearly within the through hole 230. The through hole 230 makes the movement of the pressing rod 310 smoother and can avoid friction between the pressing rod 310 and the cover plate 200 during the movement, thereby improving the service life of the pressing device 300.

[0041] In addition, to further improve the performance of the pressing device 300, a spring can be provided on the pressing rod 310. One end of the spring is connected to the abutment plate 320, and the other end of the spring is connected to the cover plate 200. When the external force is removed, the spring can drive the abutment plate 320 and the pressing rod 310 to reset, so that the pressing device 300 can be reused.

[0042] This application also includes a new embodiment, which specifically includes:

[0043] A linear groove 240 is provided on the cover plate 200, and each groove 240 is provided with a corresponding pressing rod 310. A slider 250 is provided in the groove 240 and is slidably connected to the groove 240. The pressing device 300 is connected to the slider 250. When it is necessary to move the pressing device 300, the slider 250 can be pushed by external force, so that the slider 250 drives the pressing device 300 to move along the groove 240, thereby realizing the position adjustment of the pressing device 300, which facilitates the replacement of the date template 500 of the mold in different positions.

[0044] A second fixing groove 251 is provided on the side of the slider 250 facing the base plate 100. A date template 500 is installed in the second fixing groove 251. The date template 500 moves along the slide groove 240 with the slider 250. When it is necessary to replace the date template 500 of the mold, the slider 250 can be moved to the position of the corresponding mold, and then the pressing device 300 can be pushed so that the pressing device 300 presses the date template 500 onto the mold, thus completing the replacement of the date template 500.

[0045] The slide groove 240 has abutment grooves 241 on both sides, which are connected to the slide groove 240. The slider 250 is provided with a slider 252 at the position corresponding to the abutment groove 241. The slider 252 is located in the abutment groove 241 and slides along the direction of the abutment groove 241. The abutment groove 241 can limit the movement of the slider 250 and prevent the slider 250 from leaving the slide groove 240 during movement, thereby improving the stability of the movement of the slider 250.

[0046] An abutment block 253 is provided on the slider 252 at a position away from the slider 250. The abutment block 253 abuts against the bottom of the abutment groove 241. When the slider 250 moves to the end of the groove 240, the abutment block 253 can abut against the bottom of the groove 241 to limit the movement of the slider 250 and prevent the slider 250 from continuing to move and disengaging from the groove 240.

[0047] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
