Description

Technical Field

[0001] The present application relates to the technical field of surface flatness measuring instruments, and in particular to a surface flatness measuring instrument. Background Art

[0002] A surface flatness measuring instrument is an instrument used to measure the flatness of a workpiece surface. It is commonly used in the fields of engineering, manufacturing, and quality control. A surface flatness measuring instrument can help determine the flatness, flatness, verticality, parallelism, and other parameters of a workpiece surface, thereby evaluating the quality and accuracy of the workpiece surface. The working principle of a surface flatness measuring instrument is usually to scan the workpiece surface in contact or non-contact through a sensor (such as an optical sensor, laser sensor, etc.), and then transmit the data to a computer or display screen for analysis and display. These instruments can provide high-precision surface flatness measurement results, helping users understand the actual situation of the workpiece surface and make necessary adjustments and improvements. In the manufacturing process, surface flatness measuring instruments are widely used to ensure product quality and improve production efficiency.

[0003] During the measurement process of the surface flatness measuring instrument, it is necessary to select micrometers of different accuracy for different inspection objects. To replace the micrometer, the micrometer of the original accuracy needs to be removed by loosening the bolts, and then replaced with the required micrometer. After placing it, the bolts need to be tightened to reinforce the micrometer. The installation process takes a lot of time. Utility Model Content

[0004] The present application proposes a surface flatness measuring instrument to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, this application adopts the following technical solutions:

[0006] A surface flatness measuring instrument comprises a supporting mechanism, wherein a mounting mechanism is mounted on the upper end of the supporting mechanism, a measuring mechanism is slidably connected to one end of the mounting mechanism away from a connection point of the supporting mechanism, and a fixing mechanism is arranged inside one end of the mounting mechanism close to the measuring mechanism.

[0007] As a preferred embodiment, the support mechanism includes a base plate, one end of the upper surface of the base plate is threadedly connected to a support column, and a mounting mechanism is installed on the middle side of the support column.

[0008] By adopting the above technical solution, the supporting mechanism is responsible for supporting the installation mechanism and the measuring mechanism to ensure stability during measurement.

[0009] As a preferred embodiment, the mounting mechanism includes a bite block, a fixing bolt is threadedly connected to one side of the bite block, a sliding hole is provided in the middle of the bite block, the inside of the sliding hole is slidably connected to the side of the support column, a gap is provided between the sliding hole and the back of the bite block, a connecting rod is fixedly connected to the front of the bite block, a cross groove is provided at one end of the connecting rod away from the bite block, and the upper and lower grooves of the cross groove are arranged through the upper and lower surfaces of the connecting rod.

[0010] By adopting the above technical solution, the installation mechanism is responsible for connecting the supporting mechanism and the measuring mechanism, and at the same time provides an installation position for the measuring mechanism.

[0011] As a preferred embodiment, the measuring mechanism includes a measuring instrument, a slider is fixedly connected in the middle of the measuring instrument, side blocks are fixedly connected on the left and right sides of the slider, oblique cuts are opened on the bottom of the front and back faces of the side blocks, and the longitudinal section of the slider and the side blocks has the same shape as the longitudinal section of the cross groove.

[0012] By adopting the above technical solution, the measuring mechanism is the main body for measuring the surface flatness.

[0013] As a preferred embodiment, the fixing mechanism includes a guide groove, which is opened on the groove walls on both sides of the cross groove, and a pressure spring is fixedly connected to the bottom of the guide groove, and a fixed plug is fixedly connected to the upper end of the pressure spring, and the fixed plug is slidably connected to the groove wall of the guide groove, and the top of the fixed plug is conically set.

[0014] By adopting the above technical solution, the fixing mechanism limits the measuring mechanism, thereby preventing the measuring mechanism from moving forwards and backwards during the measuring process.

[0015] As a preferred embodiment, a ball bearing is installed at the lower end of the measuring instrument.

[0016] By adopting the above technical solution, the arrangement of the ball can reduce the friction force on the lower end of the measuring instrument, thereby reducing the possibility that the measuring mechanism is carried away from the cross groove by the friction force during the measurement process.

[0017] Beneficial effects of this application:

[0018] The surface flatness measuring instrument has the advantages that when it is necessary to replace the measuring instrument, the original surface flatness measuring instrument only needs to be pushed down from one end of the installation mechanism, and the fixed plug will slide into the guide groove under the action of the extrusion force, so that the surface flatness measuring instrument can slide out of the cross groove smoothly, and then the required surface flatness measuring instrument is pushed and slid into the cross groove in the same way. When the rear side of the surface flatness measuring instrument contacts the bottom of the cross groove, the fixed plug will move up under the action of the pressure spring and limit the measuring mechanism. The installation is fast and the operation is simple and convenient, thereby improving the installation efficiency and saving the measurement time. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0025] Reference Figure 1 , 4 A surface flatness measuring instrument includes a supporting mechanism 1, a mounting mechanism 2 is mounted on the upper end of the supporting mechanism 1, a measuring mechanism 3 is slidably connected to the end of the mounting mechanism 2 away from the connection point of the supporting mechanism 1, and a fixing mechanism 4 is arranged inside the end of the mounting mechanism 2 close to the measuring mechanism 3.

[0026] Reference Figure 2 The support mechanism 1 includes a bottom plate 101, a support column 102 is threadedly connected to one end of the upper surface of the bottom plate 101, and a mounting mechanism 2 is installed on the middle side of the support column 102. The bottom plate 101 is placed on a stable table, and then the support column 102 is threadedly connected to the bottom plate 101 to ensure that the support column 102 is vertical to the bottom plate 101 and the bottom plate 101 is stable and does not shake, and the placement and installation of the support mechanism 1 is completed.

[0027] Reference Figure 2The mounting mechanism 2 includes a snap block 201, one side of which is threadedly connected with a fixing bolt 202, a sliding hole 203 is provided in the middle of the snap block 201, the inside of the sliding hole 203 is slidably connected with the side of the support column 102, a gap is provided between the sliding hole 203 and the back of the snap block 201, a connecting rod 204 is fixedly connected to the front of the snap block 201, and a cross groove 205 is provided at one end of the connecting rod 204 away from the snap block 201, and the upper and lower grooves of the cross groove 205 penetrate the upper and lower surfaces of the connecting rod 204. The snap block 201 on the side of the support column 102 is adjusted to a suitable relative position, and the fixing bolt 202 is rotated, and the fixing bolt 202 drives the snap block 201 to squeeze the side of the support column 102, thereby achieving the fixing of the position of the mounting mechanism 2.

[0028] Reference Figure 2 The measuring mechanism 3 includes a measuring instrument 301, a slider 302 is fixedly connected in the middle of the measuring instrument 301, side blocks 303 are fixedly connected on the left and right sides of the slider 302, and oblique cuts 304 are opened at the bottom of the front and back sides of the side blocks 303. The longitudinal sections of the slider 302 and the side blocks 303 have the same shape as the longitudinal section of the cross groove 205. The slider 302 and the side blocks 303 are placed in the cross groove 205, and the measuring mechanism 3 is pushed to slide along the direction of the cross groove 205 until the back of the slider 302 contacts the bottom of the groove, and the placement of the measuring mechanism 3 is completed.

[0029] Reference Figure 4 The fixing mechanism 4 includes a guide groove 401, which is provided on the groove walls on both sides of the cross groove 205. A pressing spring 402 is fixedly connected to the bottom of the guide groove 401, and a fixing plug 403 is fixedly connected to the upper end of the pressing spring 402. The fixing plug 403 is slidably connected to the groove wall of the guide groove 401, and the top of the fixing plug 403 is conical. When the measuring mechanism 3 is pushed into the cross groove 205, the oblique cut 304 on the back of the side block 303 will squeeze the fixing plug 403 into the guide groove 401. When the measuring mechanism 3 is pushed into the cross groove 205, the fixing plug 403 will extend out of the guide groove 401 under the action of the pressing spring 402, thereby limiting the measuring mechanism 3.

[0030] Reference Figure 3 , a ball 305 is installed at the lower end of the measuring instrument 301. When the measuring instrument 301 is measuring, the lower end of the measuring instrument 301 will slide along the surface of the object. The arrangement of the ball 305 can reduce the friction force on the lower end of the measuring instrument 301, thereby reducing the possibility that the measuring mechanism 3 is carried away from the cross groove 205 by the friction force during the measurement process.

[0031] Working principle: Place the base plate 101 on a stable table, then thread the support column 102 to the base plate 101 to ensure that the support column 102 is perpendicular to the base plate 101 and the base plate 101 is stable and does not shake, thus completing the placement and installation of the support mechanism 1. Adjust the bite block 201 on the side of the support column 102 to a suitable relative position, rotate the fixing bolt 202, and the fixing bolt 202 drives the bite block 201 to squeeze the side of the support column 102, thereby fixing the position of the installation mechanism 2. Place the slider 302 and the side block 303 into the cross slot 205, and push the measuring mechanism 3 to slide along the direction of the cross slot 205 until the back of the slider 302 contacts the bottom of the slot, thus completing the placement of the measuring mechanism 3;

[0032] When the measuring mechanism 3 is pushed into the cross slot 205, the oblique cut 304 on the back of the side block 303 will squeeze the fixed plug 403 into the guide slot 401. When the measuring mechanism 3 is pushed into the cross slot 205, the fixed plug 403 will extend out of the guide slot 401 under the action of the pressure spring 402, thereby limiting the position of the measuring mechanism 3. When the measuring instrument 301 is measuring, the lower end of the measuring instrument 301 will slide along the surface of the object. The provision of the ball 305 can reduce the friction force on the lower end of the measuring instrument 301, thereby reducing the possibility that the measuring mechanism 3 is carried away from the cross slot 205 by the friction force during the measurement process.
