Description

Technical Field

[0001] This utility model relates to the field of micrometer manufacturing technology, and in particular to an electronic digital micrometer. Background Technology

[0002] An electronic digital micrometer is a high-precision measuring tool that combines traditional mechanical measurement principles with modern electronic technology, enabling it to measure the dimensions of objects quickly and accurately.

[0003] Existing electronic digital micrometers consist of a screw and a nut. The screw has threads, and the nut is fixed to the frame. When the screw rotates inside the nut, it moves axially due to the threads. The measuring range is determined by the range of movement of the screw. The movement of the screw, along with the stop at the other end, clamps the object, and the size is calculated by the amount of movement of the screw. However, existing electronic digital micrometers rely on the rigid clamping of the screw and stop to fix the object being measured. This makes it difficult for operators to accurately control the clamping force when encountering fragile objects, which can easily lead to damage or failure to clamp the object securely, thus reducing the device's practicality.

[0004] Therefore, this utility model provides an electronic digital micrometer to meet the requirements. Utility Model Content

[0005] The purpose of this invention is to provide an electronic digital micrometer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electronic digital micrometer, comprising a fixed base, a micrometer rod slidably connected to one end of the inner side of the fixed base, a slider fixedly connected to one end of the micrometer rod located inside the fixed base, a lead screw fixedly connected to the other side of the slider, a motor fixedly connected to the end of the inner side of the fixed base away from the micrometer rod, a connecting frame fixedly connected to the output end of the motor, an internal threaded ring fixedly connected to the inner side of the connecting frame away from the motor, the internal threaded ring being threaded to the outside of the lead screw, and the inner side of the fixed base located on both sides of the slider... Each end of the slider is fixedly connected to a slide block. The two ends of the slider are slidably connected to the inner sides of the two slide blocks respectively. A pressing assembly is fixedly connected to the side of the micrometer rod away from the slider. The pressing assembly includes an inner plate fixedly connected to the outside of the micrometer rod. Several pressing springs are fixedly connected to the side of the inner plate away from the micrometer rod. The other side of the several pressing springs is fixedly connected to the same contact plate. A sliding rod is fixedly connected to the middle of the side of the contact plate near the inner plate. The other end of the sliding rod passes through the inner plate and extends to the inside of the micrometer rod. An inner groove for the sliding rod to move is opened inside the micrometer rod.

[0007] In a preferred embodiment, a base frame is fixedly connected to the bottom of the fixed base near the micrometer rod, and a stop block is fixedly connected to the inner side of the base frame away from the fixed base. The stop block is at the same height as the micrometer rod.

[0008] In a preferred embodiment, the connecting frame is rotatably connected to the inside of the fixed base, and a side block is fixedly connected to the side of the lead screw away from the slider.

[0009] In a preferred embodiment, the slider includes locking blocks fixedly connected to both sides, and the inner side of the slide block is provided with a groove for the locking blocks to slide.

[0010] In a preferred embodiment, a housing is fixedly connected to the outer side of the mounting base, and a digital display screen is fixedly connected to one side of the housing.

[0011] In a preferred embodiment, the number of compression springs is six, which are arranged in a ring between the inner plate and the contact plate.

[0012] In a preferred embodiment, an anti-slip sleeve is fixedly connected to the outer end of the mounting base away from the outer shell.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model, by setting a contact plate, a compression spring, and a sliding rod, allows the micrometer rod to push the contact plate to contact the object, and cooperates with the abutment block to clamp the object. Then, the contact plate pushes the compression spring to deform, and the object is pre-fixed by the elastic force of the compression spring until the sliding rod abuts the end of the inner groove away from the inner plate, completing the measurement. This avoids rigid clamping of the object and ensures stable clamping of the object by the compression spring, thus improving the practicality of the device.

[0015] This utility model, by setting up a slider, a slide block, and an inner screw ring, allows the device to drive the lead screw to move through the inner screw ring. Through the cooperation of the slider and the slide block, not only is the rotation of the micrometer rod along with the lead screw avoided, but the stability of the micrometer rod's displacement is also ensured, ensuring that it can cooperate with the stop block to achieve stable clamping of the object, thus improving the stability of the device.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention; the conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Please see Figures 1-3 This utility model provides an electronic digital micrometer, including a fixed base 1. A micrometer rod 2 is slidably connected to one end of the inner side of the fixed base 1. A slider 3 is fixedly connected to one end of the micrometer rod 2 located inside the fixed base 1. A lead screw 4 is fixedly connected to the other side of the slider 3. A motor 5 is fixedly connected to the end of the inner side of the fixed base 1 away from the micrometer rod 2. A connecting frame 6 is fixedly connected to the output end of the motor 5. An internal thread 7 is fixedly connected to the inner side of the connecting frame 6 away from the motor 5. The internal thread 7 is threaded to the outside of the lead screw 4. Both ends of the slider 3 on the inner side of the fixed base 1 are fixedly connected to... The slide block 3 is connected to the inner sides of the two slide blocks 8 respectively. The micrometer rod 2 is fixedly connected to the pressing component 9 on the side away from the slide block 3. The bottom of the fixed seat 1 near the micrometer rod 2 is fixedly connected to the base frame 11. The inner side of the base frame 11 away from the fixed seat 1 is fixedly connected to the stop block 12. The stop block 12 is at the same height as the micrometer rod 2. The connecting frame 6 is rotatably connected to the inner side of the fixed seat 1. The lead screw 4 is fixedly connected to the side block away from the slide block 3. The slide block 3 includes the locking blocks fixedly connected on both sides. The inner side of the slide block 8 is provided with a sliding groove for the locking blocks to slide.

[0023] The object to be tested is placed between the extrusion assembly 9 and the stop block 12. The motor 5 is started, and the inner screw ring 7 is rotated through the connecting frame 6. This drives the lead screw 4 and the micrometer rod 2 to move towards the stop block 12, and the slider 3 slides in the slide seat 8 to ensure stable movement. This allows the micrometer rod 2 to drive the extrusion assembly 9 to move and clamp the object.

[0024] The cooperation between slider 3 and slide block 8 ensures that the micrometer rod 2 always maintains linear motion during movement, avoiding displacement deviation caused by rotation, thereby improving measurement accuracy. The cooperation between the micrometer rod 2 and the stop block 12 can stably clamp the object being measured, reducing measurement errors caused by shaking or displacement of the object being measured, ensuring the reliability of measurement results, and significantly improving the stability and practicality of the device.

[0025] Please see Figures 1-3 The extrusion assembly 9 includes an inner plate 901 fixedly connected to the outside of the micrometer rod 2. Several extrusion springs 902 are fixedly connected to the side of the inner plate 901 away from the micrometer rod 2. The same contact plate 903 is fixedly connected to the other side of the several extrusion springs 902. A slide rod 904 is fixedly connected to the middle of the side of the contact plate 903 near the inner plate 901. The other end of the slide rod 904 passes through the inner plate 901 and extends to the inside of the micrometer rod 2. An inner groove 10 for the slide rod 904 to move is opened inside the micrometer rod 2. A housing 13 is fixedly connected to the outside of the fixing seat 1. A digital display screen is fixedly connected to one side of the housing 13. There are six extrusion springs 902, which are distributed in a ring between the inner plate 901 and the contact plate 903. An anti-slip sleeve is fixedly connected to the end of the fixing seat 1 away from the housing 13.

[0026] After the contact plate 903 comes into contact with the object being measured, the compression spring 902 is elastically deformed and rebounds to push the contact plate 903 to fit the object. At the same time, the slide bar 904 slides in the inner groove 10 until the slide bar 904 abuts against the end of the inner groove 10 away from the inner plate 901. The size of the object is measured by the movement distance of the micrometer bar 2 and displayed on the digital display screen.

[0027] When the micrometer bar 2 pushes the contact plate 903 to contact the object being measured, the contact plate 903 gradually moves towards the inner plate 901, thereby pushing the compression spring 902 to deform. The deformation of the compression spring 902 generates a certain rebound force, which pre-fixes the object being measured between the micrometer bar 2 and the stop block 12. This flexible clamping method avoids rigid clamping of the object being measured, reducing the risk of damage to the surface of the object being measured. It is especially suitable for measuring objects with relatively fragile surfaces or high precision requirements. This means that the device not only avoids rigid clamping of the object being measured and reduces the risk of damage, but also ensures stable clamping of the object being measured through the elastic support of the compression spring 902, thereby improving the accuracy and reliability of the measurement.

[0028] The working principle and usage process of this utility model are as follows: The object to be tested is placed between the extrusion assembly 9 and the abutment block 12. The motor 5 is started, and the inner screw ring 7 is rotated through the connecting frame 6. This drives the lead screw 4 and the micrometer rod 2 to move towards the abutment block 12, while the slider 3 slides in the slide seat 8 to ensure stable movement. This allows the micrometer rod 2 to drive the extrusion assembly 9 to move and clamp the object. After the contact plate 903 contacts the object to be tested, the extrusion spring 902 undergoes elastic deformation and rebounds to push the contact plate 903 to adhere to the object. At the same time, the slide rod 904 slides in the inner groove 10 until the slide rod 904 abuts against the end of the inner groove 10 away from the inner plate 901. The size of the object is measured by the movement distance of the micrometer rod 2 and displayed on the digital display screen.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
