Description

Technical Field

[0001] This utility model relates to the field of quality inspection equipment technology, specifically a quality inspection device for mandrel production and processing. Background Technology

[0002] As a key component in mechanical transmission, the quality of the spindle directly affects the operating performance of the equipment.

[0003] Based on the above, the inventors have discovered the following problems: In the coaxiality testing stage after mandrel processing, the traditional method relies on manual adjustment of a dial indicator for measurement. Operators need to repeatedly adjust the position and extension length of the dial indicator to make the test head fit against the mandrel surface. This process is not only time-consuming but also requires a high level of operator proficiency. In mass production scenarios, this seriously affects production progress and prolongs the waiting time for subsequent processes.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a quality inspection device for mandrel production and processing, in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this invention is to provide a quality inspection device for mandrel production and processing, so as to solve the problem mentioned in the background art that the traditional method relies on manual adjustment of a dial indicator for measurement in the coaxiality detection stage after mandrel processing.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A quality inspection device for mandrel manufacturing includes a main body, a moving mechanism, and an adjusting mechanism. The main body includes a base, a support frame fixedly mounted on one side of the upper end of the base, and a three-jaw chuck rotatably connected to one side of the upper end of the support frame. The moving mechanism includes a moving box, the bottom side of which is connected to one side of the base, and a controller is mounted on one side of the moving box. The adjusting mechanism includes a first adjusting seat and a second adjusting seat, the bottom end of which is slidably connected to the upper end of the moving box. A first adjusting rod and a second adjusting rod are slidably mounted inside the first and second adjusting seats, respectively. The top end of the first adjusting rod is connected to the bottom side of the second adjusting seat, and a dial indicator is inserted into one end of the second adjusting rod.

[0008] Furthermore, a first laser rangefinder is installed on one side of the upper end of the second adjusting rod, and a second laser rangefinder is installed on the upper end of the base at the bottom of the axis of the three-jaw chuck.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the first laser rangefinder sensor and the second laser rangefinder sensor work together to measure the relative position of the dial indicator and the spindle axis in real time, providing positioning data for the adjustment mechanism, ensuring that the dial indicator probe accurately contacts the part of the spindle to be measured, and improving the detection accuracy and reliability.

[0010] Furthermore, a first servo motor is fixedly installed at one end of the interior of both the first and second adjustment seats, and a screw is sleeved on the output end of each of the first servo motors.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the first servo motor drives the screw to rotate, and through the threaded transmission with the sleeve, the rotational motion is converted into the linear motion of the first and second adjusting rods, thereby realizing the displacement of the dial indicator and adapting to the detection needs of mandrels of different specifications.

[0012] Furthermore, a sleeve is embedded at one end of both the first and second adjusting rods, and the screw and the sleeve are threadedly connected.

[0014] Furthermore, the movable box is internally rotatably connected to a lead screw, and a slider is threaded onto the lead screw. The top end of the slider is connected to the bottom end of the first adjusting seat.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the threaded transmission between the lead screw and the slider converts the rotational motion of the lead screw into the linear motion of the slider, which drives the first adjusting seat and the adjusting mechanism to move laterally along the moving box, making it easier for the dial indicator to be aligned with different detection positions of the mandrel and expanding the detection range.

[0016] Furthermore, a second servo motor is fixedly installed at one end of the mobile box, and the output end of the second servo motor is connected to the lead screw drive.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the second servo motor provides power to the lead screw, realizing the lateral movement of the adjustment mechanism and improving the detection efficiency.

[0018] Furthermore, a third servo motor is fixedly installed on the other side of the upper end of the support frame, and the output end of the third servo motor is connected to the three-jaw chuck for transmission.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the third servo motor drives the three-jaw chuck to rotate smoothly, which in turn drives the mandrel to rotate at a constant speed, so that the dial indicator continuously collects data during the rotation of the mandrel to detect the roundness of the mandrel and ensure that the test results are comprehensive and reliable.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0030] Please see Figures 1-5 A first laser rangefinder 305 is mounted on one side of the upper end of the second adjusting rod 304. A second laser rangefinder 105 is mounted on the lower end of the upper surface of the base 101, located at the axis of the three-jaw chuck 104. A first servo motor 307 is fixedly mounted on one end of the interior of both the first adjusting seat 301 and the second adjusting seat 303. A screw 308 is sleeved on the output end of each of the first servo motors 307. A sleeve 309 is embedded on one end of each of the first adjusting rod 302 and the second adjusting rod 304. The screw 308 and the sleeve 309 are threadedly connected. A lead screw 204 is rotatably connected inside the moving box 201. 4. The threaded connection should include a slider 205. The top of the slider 205 is connected to the bottom of the first adjusting seat 301. A second servo motor 203 is fixedly installed at one end of the moving box 201. The output end of the second servo motor 203 is connected to the lead screw 204. A third servo motor 103 is fixedly installed on the other side of the upper end of the support frame 102. The output end of the third servo motor 103 is connected to the three-jaw chuck 104. The first laser rangefinder 305 and the second laser rangefinder 105 cooperate to measure the relative position of the dial indicator 306 and the spindle axis in real time, providing positioning data for the adjusting mechanism 3 to ensure the accuracy of the dial indicator. The dial indicator 306 probe accurately contacts the part to be measured on the mandrel, improving detection accuracy and reliability. The first servo motor 307 drives the screw 308 to rotate, and through the threaded transmission with the sleeve 309, the rotational motion is converted into the linear motion of the first adjusting rod 302 and the second adjusting rod 304, realizing the displacement of the dial indicator 306. This adapts to the detection needs of mandrels of different specifications. The threaded connection between the sleeve 309 and the screw 308 ensures the stable movement of the first adjusting rod 302 and the second adjusting rod 304, avoiding shaking or offset during adjustment, making the dial indicator 306 accurately positioned, and ensuring the accuracy of the detection data. The lead screw 204 and the slide... The threaded drive of block 205 converts the rotational motion of lead screw 204 into the linear motion of slider 205, driving the first adjusting seat 301 and adjusting mechanism 3 to move laterally along the moving box 201, making it easier for dial indicator 306 to align with different detection positions of the mandrel and expand the detection range. The second servo motor 203 provides power to lead screw 204, realizing the lateral movement of adjusting mechanism 3 and improving detection efficiency. The third servo motor 103 drives the three-jaw chuck 104 to rotate smoothly, driving the mandrel to rotate at a uniform speed, so that dial indicator 306 continuously collects data during the rotation of the mandrel for detecting the roundness of the mandrel, ensuring that the detection results are comprehensive and reliable.

[0031] Specifically, the working principle of this quality inspection device for mandrel production and processing is as follows: In use, the mandrel is first fixed on the three-jaw chuck 104. The third servo motor 103 drives the three-jaw chuck 104 to rotate, causing the mandrel to rotate at a uniform speed. Subsequently, the operator starts the second servo motor 203 through the controller 202, which drives the lead screw 204 to rotate. The threaded transmission between the lead screw 204 and the slider 205 causes the first adjusting seat 301 to move laterally along the moving box 201, initially adjusting the lateral position of the dial indicator 306. Then, the first servo motor 307 inside the first adjusting seat 301 and the second adjusting seat 303 starts, driving the lead screw 30... 8. Rotation: The threaded transmission of screw 308 and sleeve 309 controls the extension and retraction of the first adjusting rod 302 and the second adjusting rod 304 respectively, realizing the precise positioning of dial indicator 306 in the vertical and longitudinal directions. During the adjustment process, the first laser ranging sensor 305 and the second laser ranging sensor 105 measure the relative position of dial indicator 306 and the spindle axis in real time and feed the data back to controller 202 to ensure that the probe of dial indicator 306 accurately contacts the part to be measured on the spindle. After dial indicator 306 is in place, the spindle continues to rotate under the drive of three-jaw chuck 104, and dial indicator 306 continuously collects data to detect the roundness of the spindle.
