Description

Technical Field

[0001] This utility model relates to the field of mechanical parts measurement technology, and in particular to a portable mechanical parts measurement tool. Background Technology

[0002] Portable mechanical parts measuring tools are small, easy to carry, and can quickly and accurately measure the size, shape, and position parameters of mechanical parts in field or mobile scenarios. These tools are used in mechanical manufacturing, maintenance, quality inspection, aerospace, and automotive industries, and can meet flexible measurement needs.

[0003] Among measuring tools, portable tools are only suitable for small and medium-sized parts. For large workpieces, multiple splicing measurements are required, which leads to a high risk of error accumulation. Existing technology uses telescopic electronic measuring rulers, which can extend the measuring range from 300 mm to 2000 mm. With a magnetic base, they can be attached to the workpiece surface and are suitable for segmented measurement of long shaft parts. However, in actual use, the use of telescopic electronic measuring rulers can cause the internal structure to loosen after long-term use, resulting in a decrease in measurement accuracy. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a portable mechanical parts measuring tool, which aims to improve the problem that the internal structure of the telescopic electronic measuring ruler used in the prior art becomes loose after long-term use, resulting in a decrease in its measurement accuracy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a portable mechanical parts measuring tool, including a measuring frame, a fixing frame fixedly connected to the top left side of the outer wall of the measuring frame, a display screen fixedly connected to the middle front side of the fixing frame, a mounting groove opened on the top left side of the fixing frame, a screw threadedly connected to the top left end of the front side of the fixing frame, a clamping frame provided on the left side of the fixing frame, two threaded holes opened on the right front end of the clamping frame, a handle fixedly connected to the left side of the clamping frame, a connecting plate fixedly connected to the right side of the clamping frame, screws threadedly connected to the four corners on the right side of the connecting plate, a distance extending plate fixedly connected to the right side of the connecting plate, a measuring column slidably connected to the left side of the measuring frame, and clamping mechanisms provided on the bottom front and rear sides of the clamping frame.

[0006] As a further description of the above technical solution:

[0007] The clamping mechanism includes two mounting plates, which are fixedly connected to the bottom of the front and rear sides of the clamping frame. Two fixing blocks are fixedly connected to the opposite sides of the two mounting plates. Rotating rods are rotatably connected between the adjacent two front fixing blocks and between the adjacent two rear fixing blocks. Support plates are fixedly connected to the right side of the two rotating rods, and clamping rings are fixedly connected to the right side of the two support plates.

[0008] As a further description of the above technical solution:

[0009] A lamp holder is fixedly connected to the upper front side of the mounting bracket, and an indicator light is fixedly connected to the front side of the lamp holder.

[0010] As a further description of the above technical solution:

[0011] Two buttons are fixedly connected to the bottom front side of the mounting bracket, and both buttons are designed symmetrically.

[0012] As a further description of the above technical solution:

[0013] Both screws are fixedly connected to washers on their outer walls, and the outer walls of both washers are designed with rounded edges.

[0014] As a further description of the above technical solution:

[0015] Multiple anti-slip tubes are fixedly connected between adjacent clamping rings, and the multiple anti-slip tubes are fixedly connected at equal intervals between adjacent clamping rings.

[0016] As a further description of the above technical solution:

[0017] Multiple anti-slip strips are fixedly connected to the right side of the outer wall of the measuring frame, and the multiple anti-slip strips adopt a ring design.

[0018] As a further description of the above technical solution:

[0019] The diameter of the right side of the clamping bracket is smaller than the inner diameter of the mounting groove, and the outer wall of each of the two screws matches the inside of the threaded hole.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the right side of the clamping frame is inserted into the mounting slot of the fixing frame. A screw is used to pass through the threaded hole between the front side of the fixing frame and the clamping frame, and then screwed into the rear side of the mounting slot for fixation. When the distance needs to be extended, the clamping frame is removed by removing screw one, and the connecting plate and the distance extending plate are fixed to the right side of the clamping frame by screw two, and then inserted into the mounting slot for fixation. When measuring, the handle is held by hand, which makes it convenient to carry and increases stability, thereby improving the measurement accuracy.

[0022] 2. In this utility model, the fixing blocks are symmetrically fixed to the bottom of the clamping frame by the mounting plate. The rotating rod is rotatably connected to the fixing blocks by the bearing, so that the support plate can rotate around the axis. Manually rotating the support plate drives the rotating rod to rotate, so that the clamping ring fixed on the right side of the support plate rotates synchronously. When the arc-shaped structure of the clamping ring fits the object being measured, it offsets the lateral force, restricts the shaking displacement of the object, ensures that the position is fixed during measurement, and improves the accuracy of the data.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a portable mechanical parts measuring tool, including a measuring frame 1. A fixing frame 3 is fixedly connected to the top left side of the outer wall of the measuring frame 1. A display screen 4 is fixedly connected to the middle front side of the fixing frame 3 for displaying measurement data. A mounting groove 5 is provided on the top left side of the fixing frame 3. A screw 6 is threadedly connected to the top left end of the front side of the fixing frame 3. A clamping frame 7 is provided on the left side of the fixing frame 3. Two threaded holes 8 are provided on the right front side of the clamping frame 7. The right side of the clamping frame 7 can be inserted into the interior of the mounting groove 5. Then, the screw 6 passes through the front side of the fixing frame 3 and the interior of the threaded holes 8, and is threadedly connected to the rear interior of the mounting groove 5, facilitating the disassembly of the clamping frame 7. For easy carrying, the left side of the clamping frame 7 is fixedly connected to a handle 9 for easy handling. The right side of the clamping frame 7 is fixedly connected to a connecting plate 10. Each of the four corners on the right side of the connecting plate 10 is threaded with a screw 11. An extender plate 12 is fixedly connected to the right side of the connecting plate 10. When the measurement distance is insufficient, remove the screw 6, take out the clamping frame 7, fix the connecting plate 10 to the right side of the clamping frame 7 with the screw 11, insert the extender plate 12 into the mounting slot 5, and then tighten the screw 6 to increase the measurement distance. The left side of the measuring frame 1 is slidably connected to a measuring column 13 for detecting the width of the object. The clamping frame 7 is equipped with clamping mechanisms 2 at the bottom of both the front and rear sides.

[0032] Specifically, a fixed frame 3 is fixedly connected to the top left side of the outer wall of the measuring frame 1. A display screen 4 is embedded in the middle of its front side, which can clearly display the measurement data in real time for easy reading by the operator. A mounting groove 5 is opened on the top left side of the fixed frame 3, and a screw 6 is provided on the top left end of the front side, which is connected to the fixed frame 3 by threads. On the left side of the fixed frame 3, two threaded holes 8 are opened on the right side of the front side of the clamping frame 7. When installation is required, its right side is inserted into the mounting groove 5, and then the screw 6 is turned so that it passes through the front side of the fixed frame 3 and the threaded hole 8, and engages with the thread on the inner wall of the rear side of the mounting groove 5, thereby fixing it. Disassembly is only required by reversing the operation, which is easy and convenient and easy to carry. A handle 9 is welded to the left side of the clamping frame 7, which is convenient for the operator to hold and move with one hand. A connecting plate 10 is fixedly connected to its right side. Threaded holes are machined at the four corners on the right side of the plate. Matching screws 11 can tighten the extension plate 12 to the connecting plate 10. When the measurement distance is insufficient, screw 6 can be removed first, clamp 7 can be taken off, and connecting plate 10 can be fixed to the right side of clamp 7 with screw 11. Then, extender plate 12 can be aligned and inserted into mounting slot 5. Finally, screw 6 can be screwed back on to effectively expand the measurement range and meet the inspection needs of workpieces of different sizes. The left side of measuring frame 1 is designed with a sliding measuring column 13, which adopts high-precision guide rail and can slide smoothly in the horizontal direction. During operation, the object to be measured is placed between the measuring column 13 and the reference surface of measuring frame 1. The measuring column 13 is electrically driven to fit against the surface of the object. With the real-time data feedback of display screen 4, the width of the object can be accurately detected, ensuring portability. It can also be flexibly adapted to different measurement scenarios through component combination. It is especially suitable for industrial application scenarios such as on-site rapid inspection and workpiece size calibration, which significantly improves measurement efficiency and operation convenience.

[0033] Reference Figure 2 and Figure 5 The clamping mechanism 2 includes two mounting plates 201. The two mounting plates 201 are fixedly connected to the bottom of the front and rear sides of the clamping frame 7. Two fixing blocks 202 are fixedly connected to the opposite sides of the two mounting plates 201. Rotating rods 203 are rotatably connected between the adjacent two front fixing blocks 202 and between the adjacent two rear fixing blocks 202. The rotating rods 203 can rotate between the fixing blocks 202. Support plates 204 are fixedly connected to the right side of the two rotating rods 203. Clamping rings 205 are fixedly connected to the right side of the two support plates 204. When it is necessary to clamp an object, the support plates 204 are manually rotated so that the clamping rings 205 also rotate to clamp the object being measured and prevent inaccurate measurement.

[0034] Specifically, two mounting plates 201 are fixedly connected to the bottom of the front and rear sides of the clamping frame 7. Each mounting plate 201 has two fixing blocks 202 vertically fixed on the opposite side, which are symmetrically distributed. A rotating rod 203 is provided between the fixing blocks 202 on the front and rear sides. The two ends of the rotating rod 203 are rotatably connected to the fixing blocks 202 through bearings to ensure that the rotating rod 203 can rotate flexibly and is axially stable. A support plate 204 is fixedly welded to the right end of the rotating rod 203. The plate surface is rectangular, and the part extending from the right side is fixedly connected to a clamping ring 205. The clamping ring 205 is made of an arc-shaped metal plate. When it is necessary to clamp the object to be measured, the operator manually holds the support plate 204 and drives the rotating rod 203 to rotate between the fixing blocks 202, so that the clamping ring 205 rotates synchronously to fit the outside of the object. This can effectively counteract the lateral force during measurement and avoid measurement deviation caused by shaking or displacement of the object.

[0035] Reference Figure 1 and Figure 3 A lamp holder 14 is fixedly connected to the upper middle part of the front side of the mounting bracket 3. An indicator light 15 is fixedly connected to the front side of the lamp holder 14. The light turns on when measuring and turns off when not in use. Two buttons 16 are fixedly connected to the bottom front side of the mounting bracket 3. Both buttons 16 are symmetrically designed and used to control the opening or closing. Washers 17 are fixedly connected to the outer walls of both screws 16. The outer walls of both washers 17 are rounded to prevent the screws 16 from being tightened.

[0036] Specifically, a lamp holder 14 is vertically fixed to the upper middle part of the front side of the mounting bracket 3, and an indicator light 15 is embedded in its front end, emitting a clear red or green light to intuitively display the working status of the equipment; it can be manually turned off when not measuring to reduce energy consumption. Two buttons 16 are symmetrically arranged at the bottom front side of the mounting bracket 3, which correspond to the on and off functions of the indicator light 15, respectively, and can be operated with one hand. Washers 17 are fitted on the outside of the screws of the two screws 6, and the edges are rounded and chamfered to avoid sharp edges scratching the operator or the surface of the workpiece, and to prevent the mounting groove 5 or threaded hole 8 from being deformed due to the screws 6 being tightened too much.

[0037] Reference Figure 1 and Figure 4 Multiple anti-slip tubes 18 are fixedly connected between adjacent clamping rings 205. The multiple anti-slip tubes 18 are fixedly connected at equal intervals between adjacent clamping rings 205 to increase the friction with the object being measured. Multiple anti-slip strips 19 are fixedly connected to the right side of the outer wall of the measuring frame 1. The multiple anti-slip strips 19 adopt a ring design to increase the friction with the hand. The diameter of the right side of the clamping frame 7 is smaller than the inner diameter of the mounting groove 5. The outer walls of the two screws 6 are matched with the inside of the threaded hole 8.

[0038] Specifically, multiple anti-slip tubes 18 are fixedly connected to the inner sides of the two clamping rings 205. These anti-slip tubes 18 are distributed in a ring at equal intervals and have fine textures on their surfaces. When the clamping rings 205 clamp the object being measured, the anti-slip tubes 18 fit tightly against the surface of the object through elastic deformation. Their rough texture can significantly increase the friction. Multiple ring-shaped anti-slip strips 19 are provided on the right side of the outer wall of the measuring frame 1. They adopt a raised ribbed design. When the operator holds the measuring frame 1, the palm and the concave and convex structure of the anti-slip strips 19 form a mechanical engagement, avoiding measurement errors or equipment damage caused by the tool slipping. The diameter of the cylinder on the right side of the clamping frame 7 is slightly smaller than the inner diameter of the mounting groove 5, forming a clearance fit to ensure the smooth insertion of the clamping frame 7 into the mounting groove 5. The outer diameter of the threads of the two screws 6 is strictly matched with the inner diameter of the threaded hole 8 of the clamping frame 7 to ensure a tight engagement and uniform force when screwed in.

[0039] Working principle: Insert the right side of the clamping frame 7 into the mounting slot 5 of the fixing frame 3. Screw 6 passes through the threaded hole 8 on the front side of the fixing frame 3 and the clamping frame 7, and is threadedly connected and fixed to the inner wall of the rear side of the mounting slot 5. When it is necessary to extend the measurement distance, remove screw 6 to remove the clamping frame 7. Fix the connecting plate 10 and the extension plate 12 to the right side of the clamping frame 7 with screw 11. Then insert the extension plate 12 into the mounting slot 5 and screw 6 back to complete the installation of the extension component. During measurement, hold the handle 9 to move the device and place the object to be measured between the reference surface of the measuring frame 1 and the sliding measuring column 13. The electric drive of the measuring column 13 slides along the high-precision guide rail to fit the surface of the object. The measurement data is transmitted to the display screen 4 on the front side of the fixing frame 3 in real time. After the test is completed, the clamping frame 7 can be disassembled in reverse for carrying.

[0040] Furthermore, the fixing blocks 202 are symmetrically fixed to the bottom of the clamping frame 7 by the mounting plate 201. The rotating rod 203 is rotatably connected to the fixing blocks 202 through the bearing, so that the support plate 204 can rotate around the axis of the rotating rod 203. When the operator manually rotates the support plate 204, it drives the rotating rod 203 to rotate flexibly between the fixing blocks 202, thereby causing the clamping ring 205 fixed on the right side of the support plate 204 to rotate synchronously. When the arc-shaped structure of the clamping ring 205 fits against the outside of the object being measured, the symmetrically distributed front and rear sets of clamping rings 205 form a clamping force to counteract the lateral force generated during the measurement process, limit the shaking or displacement of the object, and ensure that the position of the object is fixed during the measurement, thereby improving the accuracy of the test data.

[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.
