Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a portable composite device for precise marking and height measurement. Background Technology

[0002] In the mold manufacturing industry, machining holes and grooves on parts is a common process. However, existing parts still have the following problems during machining:

[0003] Traditionally, the processing of mold parts often uses high-precision machine tools such as machining centers. While this ensures processing efficiency and accuracy, it often requires transporting the parts to a designated machine tool for processing. This not only increases processing costs but also limits processing flexibility.

[0004] To address the aforementioned problems, this utility model document proposes a portable composite device for precise line marking and height measurement. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as reliance on high-precision machine tools for traditional mold part processing, increased costs due to repeated handling of parts, and limited processing flexibility. Therefore, this invention proposes a portable composite device for precise scribing and height measurement.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A portable, precision marking and height measurement composite device, comprising:

[0008] The base has a slide rod fixedly installed on its top. A scale is provided on one side of the slide rod. A slider and a fine-tuning block are slidably sleeved on the outer wall of the slide rod. The fine-tuning block is located above the slider. The fine-tuning block and the slider cooperate to form a combination.

[0009] It also includes a locking component for positioning the assembly;

[0010] It also includes a measuring claw, which is located on one side of the slide bar and below the slider. Two second screws are threaded onto the top of the measuring claw, and the measuring claw is fixedly connected to the slider by the two second screws.

[0011] It also includes a blade, which is fixedly mounted on the bottom of the measuring jaw, and the blade is used to scribing the surface of the workpiece;

[0012] It also includes a vernier scale, and a plurality of fastening screws are threaded on one side of the slider. The vernier scale is fixedly connected to the slider by the plurality of fastening screws, and the vernier scale matches the scale on one side of the slide rod.

[0013] In one possible design, the locking assembly includes a stopper metal disposed inside the fine-tuning block, the stopper metal slidingly engaging with the outer wall of the slide rod, a third screw threadedly connected to one side of the fine-tuning block, the third screw being threadedly connected to the stopper metal, the third screw being used to securely install the stopper metal to the fine-tuning block, and a locking screw threadedly installed on one side of the fine-tuning block, one end of the locking screw abutting against one side of the stopper metal, the locking screw being located near the bottom of the stopper metal, the locking screw being used to press the stopper metal tightly against the slide rod to increase the friction between the stopper metal and the slide rod, thereby locking the assembly.

[0014] In one possible design, a micro-adjustment bolt is threaded onto the top of the slider, the top of the micro-adjustment bolt rotates through the fine-tuning block, and a micro-adjustment nut is rotatably disposed inside the fine-tuning block. The micro-adjustment nut is fixedly sleeved on the outer wall of the micro-adjustment bolt, and the micro-adjustment bolt is used to fine-tune the distance between the fine-tuning block and the slider.

[0015] In one possible design, a clamping nut is threaded on the outer wall of the micro-adjustment bolt. The clamping nut is located between the micro-adjustment block and the slider, and is used to limit the relative position between the micro-adjustment block and the slider.

[0016] In one possible design, a spring is provided inside the slider, and a set screw is threaded onto one side of the spring. The set screw is threadedly connected to the spring. An insert is fixedly installed on one side of the slider. Both the insert and the spring cooperate with the slide rod to adjust the effective gap between the slider and the slide rod so that it meets the design and usage requirements.

[0017] In one possible design, a stop ring is fixedly mounted on one side of the slide bar, the stop ring being located near the top of the slide bar, the stop ring being used to restrict the movement of the assembly.

[0018] In one possible design, a pressure plate is provided on one side of the base, and two first screws are threaded to one side of the base. The pressure plate is fixedly connected to the base by the two first screws. The slide rod is embedded in the top of the base through a slot. The pressure plate and the slide rod are pressed together to assist in completing the assembly and installation of the slide rod and the base.

[0019] In this application, when a user needs to process holes or grooves on a workpiece, the user can move the slider according to the distance and dimension requirements of the drawing. The user can find the required dimension value by aligning the scale on the connected vernier scale with the scale on the slider, and then tighten the locking screw to lock the position of the assembly for subsequent use. Next, the reference surface of the workpiece to be processed should be placed tightly against the external support plate. Larger or smaller workpieces can also be fixed on the support plate. Then, the device with the pre-determined position and dimensions is moved onto the support plate. Afterward, the user can hold the side of the base to make the base... The base is pressed firmly against the support plate, while the measuring jaws face the side of the workpiece that needs to be scribed, and the cutting edge is pressed against the workpiece surface. Then, the device is moved back and forth, and the cutting edge can leave a scribing mark on the corresponding surface of the workpiece. After that, the workpiece can be changed to a reference plane, and the above actions are repeated. At the intersection of the previous scribing mark, a center punch (one of the common tools used by fitters) is used to make a hole. This hole is the coordinate position of the hole or groove to be determined in the drawing. In this way, the user can find the positions of other holes and grooves that need to be machined on the workpiece. Finally, the workpiece is taken to the corresponding machine tool, and the corresponding hole or groove is machined by aligning it with the position of the center punch.

[0020] In addition, this device can also be used to accurately measure the height of parts, similar to the scribing method, but the difference is that the parts are pre-processed. First, the reference surface of the part and the bottom surface of the device base are placed stably on the measuring plate. The lower surface of the blade contacts the surface of the part to be measured. By adjusting the fine nut, the slider is pushed to make a fine position adjustment, so that the bottom surface of the blade is close to the surface of the part until the tightness of the contact between the two is appropriate. Then, the clamping nut is tightened, and then the scale reading is read, which is the actual height dimension of the part.

[0021] Beneficial effects: The portable precision scribing and height measurement composite device of this utility model simplifies the operation process and improves work efficiency by integrating scribing and height measurement functions into one unit; the device is designed with an accuracy of 0.02mm, which can fully meet the accuracy requirements of hole and groove position of mold parts;

[0022] In this utility model, the portable precision marking and height measurement composite device can achieve precise locking of the slider position by setting a fine adjustment block and a slider, and cooperating with a locking component, to ensure the accuracy of marking and measurement; the locking component adopts a combination of a stopper and a locking screw, and by changing the friction between the stopper and the slider, the slider can be effectively positioned, and at the same time, it can prevent the problem of loosening after long-term use.

[0023] In this utility model, the portable precision marking and height measurement composite device has a micro-adjustment bolt and a micro-adjustment nut on the top of the slider, which enables fine adjustment of the distance between the micro-adjustment block and the slider, further improving the measurement accuracy; at the same time, the setting of the clamping nut limits the relative position between the micro-adjustment block and the slider, enhancing the stability of the structure.

[0024] In this utility model, the portable precision marking and height measurement composite device can be adapted to the actual needs of production sites in different occasions by changing the size, shape and position of the base, slide bar, measuring claw and slider; in addition, it can also realize functions such as digital display through a certain degree of modification and transformation, further expanding the application range.

This device is simple, reasonable, low in manufacturing cost, quick and accurate in operation, lightweight, easy to carry, requires no special equipment or process, and is low-carbon and environmentally friendly. More importantly, it can be used for both processing and measurement, and can solve the problem of precise positioning of arbitrary coordinate holes and slots on parts and measurement of part height in existing technologies.

[0026] This utility model presents a portable precision scribing and height measurement composite device that integrates scribing and measurement functions, simplifying operation and improving work efficiency. Its high design precision effectively meets the precise positioning requirements of holes and slots in mold parts. Through the fine-tuning block, slider, and locking assembly, the slider position can be precisely locked, ensuring the accuracy of scribing and measurement. Furthermore, the device has a simple structure, is easy to carry, has adjustable dimensions, strong adaptability, and a wide range of applications. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0035] Example 1: Refer to Figure 1-6 A composite device includes components such as a base 14, a slide bar 3, a slider 7, a fine-tuning block 12, a measuring claw 5, a blade 4, and a vernier 9.

[0036] First, the base 14 serves as the supporting component for the entire device, with a slide bar 3 fixedly mounted on its top. A scale is provided on one side of the slide bar 3, serving as a reference for height measurement. A slider 7 and a fine-tuning block 12 are slidably fitted onto the outer wall of the slide bar 3. The fine-tuning block 12 is located above the slider 7 and cooperates with the slider 7 to form an adjustable assembly. This design allows the user to fine-tune the relative positions of the slider 7 and the fine-tuning block 12 as needed, thereby achieving precise marking or measurement.

[0037] To achieve the positioning of the assembly, this embodiment also includes a locking component. The locking component includes a stopper 20 disposed inside the fine-tuning block 12, which slides against the outer wall of the slide rod 3. A third screw 19 is threadedly connected to one side of the fine-tuning block 12, and the third screw 19 is threadedly connected to the stopper 20 to securely install the stopper 20 to the fine-tuning block 12. Furthermore, a locking screw 18 is threadedly installed on one side of the fine-tuning block 12, with one end of the locking screw 18 abutting against one side of the stopper 20. The locking screw 18 is located near the bottom of the stopper 20, and serves to press the stopper 20 tightly against the slide rod 3, thereby increasing the friction between the stopper 20 and the slide rod 3, and thus locking the assembly.

[0038] In this embodiment, the measuring claw 5 is located on one side of the slide bar 3 and below the slider 7. Two second screws 6 are threaded onto the top of the measuring claw 5, which securely connect the measuring claw 5 to the slider 7. A blade 4 is fixedly mounted at the bottom of the measuring claw 5; the blade 4 is used to scribing lines on the workpiece surface.

[0039] To achieve more accurate measurements, this embodiment also includes a vernier scale 9. Multiple fastening screws 8 are threaded onto one side of the slider 7, and the vernier scale 9 is fixedly connected to the slider 7 via these screws 8. The vernier scale 9 mates with the scale on one side of the slide bar 3, allowing the user to perform more precise height measurements.

[0040] To achieve fine-tuning, in this embodiment, a fine-adjustment bolt 13 is threaded onto the top of the slider 7, and the top of the fine-adjustment bolt 13 rotates through the fine-adjustment block 12. A fine-adjustment nut 11 is rotatably mounted inside the fine-adjustment block 12, and the fine-adjustment nut 11 is fixedly sleeved on the outer wall of the fine-adjustment bolt 13. By rotating the fine-adjustment bolt 13, the distance between the fine-adjustment block 12 and the slider 7 can be finely adjusted, thereby achieving more precise scribing or measurement.

[0041] In order to ensure the stability of the relative position between the fine adjustment block 12 and the slider 7, in this embodiment, the outer wall of the fine adjustment bolt 13 is threaded with a clamping nut 10. The clamping nut 10 is located between the fine adjustment block 12 and the slider 7 and is used to limit the relative position between the fine adjustment block 12 and the slider 7.

[0042] This application can be used in the field of mechanical manufacturing technology, or in other fields applicable to this application.

[0043] Example 2: Reference Figure 1 , 2 6. An improvement on Example 1: A portable composite device for precise marking and height measurement, which is applied to the field of mechanical manufacturing technology;

[0044] Furthermore, in order to adjust the effective gap between the slider 7 and the slide rod 3, a spring 17 is provided inside the slider 7 in this embodiment. A set screw 15 is threaded onto one side of the spring 17, and the set screw 15 is threadedly connected to the spring 17. An insert 16 is fixedly installed on one side of the slider 7. Both the insert 16 and the spring 17 cooperate with the slide rod 3 to adjust the gap between the slider 7 and the slide rod 3 so that it meets the design and usage requirements.

[0045] In order to prevent the assembly from exceeding the predetermined range during the sliding process, in this embodiment, a stop ring 21 is fixedly installed on one side of the slide rod 3. The stop ring 21 is located near the top of the slide rod 3 and is used to restrict the movement of the assembly.

[0046] Finally, to facilitate the assembly of the slide rod 3 and the base 14, in this embodiment, a pressure plate 2 is provided on one side of the base 14, and two first screws 1 are threaded onto one side of the base 14. The pressure plate 2 is fixedly connected to the base 14 by these two first screws 1, and the slide rod 3 is embedded in the top of the base 14 through a slot. The pressure plate 2 and the slide rod 3 are pressed together to ensure that the slide rod 3 is stably installed on the base 14.

[0047] In production practice, this device can be used to both scribing parts and measuring their height. Furthermore, by changing the size, shape, and position of the base 14, slide bar 3, measuring claw 5, and slider 7, it can be adapted to the actual needs of different production sites. It can also be modified to achieve digital display, but regardless of the specific modification, since the underlying principle remains the same, all are within the protection scope of this device.

[0048] The working principle and usage process of this technical solution are as follows:

[0049] When the user needs to process holes or grooves on a workpiece, the user can move the slider 7 according to the distance and dimension requirements of the drawing. The user can find the required dimension value by aligning the scale on the slider 3 with the connected vernier 9. Then, tightening the locking screw 18 will lock the position of the assembly for subsequent use. Next, the reference surface of the workpiece to be processed should be placed in close contact with the external support plate. Larger or smaller workpieces can also be fixed on the support plate. Then, the device with the pre-determined position and dimensions is moved onto the support plate. After that, the user can hold the side of the base 14 to make the base... 14. With the bottom surface firmly against the support plate, the measuring jaw 5 faces the side of the workpiece that needs to be scribed, and the blade 4 is pressed against the workpiece surface. Then, move the device back and forth. The blade 4 can leave a scratch on the corresponding surface of the workpiece. After that, the workpiece can be changed to a reference surface, and the above actions can be repeated. At the intersection of the previous scratch, a center punch (one of the commonly used tools of fitters) is used to make a hole. This hole is the coordinate position of the hole or groove to be determined in the drawing. In this way, the user can find the positions of other holes and grooves that need to be machined on the workpiece. Finally, the workpiece is taken to the corresponding machine tool, and the corresponding hole or groove is machined by aligning it with the position of the center punch.

[0050] In addition, this device can also be used to accurately measure the height of parts, similar to the scribing method, but the difference is that the parts are pre-processed. First, the reference surface of the part and the bottom surface of the device base 14 are both placed on the measuring plate. The lower surface of the blade 4 is in contact with the surface of the part to be measured. By adjusting the micro-nut 11, the slider 7 is pushed to make a fine position adjustment, so that the bottom surface of the blade 4 is close to the surface of the part until the tightness of the contact between the two is appropriate. Then, the clamping nut 10 is locked. Then, the scale reading is read, which is the actual height dimension of the part.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
