DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0019] Example: A dimensional inspection device for metal part processing, such as... Figures 1-3 As shown, the device includes a base 1, a controller 2, an electric slide rail 3, a moving plate 4, a reference plate 5, a distance sensor 6, a fixed plate 7, and a leveling assembly. The controller 2 and the electric slide rail 3 are mounted on the base 1. The controller 2 is equipped with a display screen and has a data storage function. The controller 2 is wired to the electric slide rail 3, and the surveyor can control the start and stop of the electric slide rail 3 through the controller 2. The moving plate 4 is slidably connected to the base 1, and the reference plate 5 is connected to the top of the moving plate 4. The distance sensor 6 is installed on the top right end of the electric slide rail 3. The distance sensor 6 and the reference plate 5 are in a straight line. The reference plate 5 is initially located at the left end of the electric slide rail 3. The electric slide rail 3 drives the moving plate 4 to move, thereby changing the distance between the reference plate 5 and the distance sensor 6. The fixed plate 7 is connected to the base 1. The fixed plate 7 is located at the right end of the base 1 and in front of the electric slide rail 3, and is parallel to the moving plate 4. The leveling assembly is provided on the fixed plate 7. The leveling assembly is used to level the metal part to be measured.

[0020] like Figure 1 and Figure 3 As shown, the leveling assembly includes a mounting plate 8, a lead screw 9, a motor 10, and a push plate 11. The lead screw 9 is rotatably connected to the fixed plate 7. The mounting plate 8 is connected to the front side of the fixed plate 7. The motor 10 is mounted on the front side of the mounting plate 8 by fixing screws. The controller 2 is wired to the motor 10. The output shaft of the motor 10 passes through the mounting plate 8 and is fixedly connected to the lead screw 9. The push plate 11 is threadedly connected to the lead screw 9. The bottom of the push plate 11 is slidably connected to the base 1, and the right side of the push plate 11 is slidably connected to the fixed plate 7.

[0021] The surveyor places the metal part to be inspected on the base 1, and then starts the motor 10 through the controller 2. The motor 10 pushes the metal part through the leveling component, and finally the metal part is attached to the electric slide rail 3. Then the controller 2 turns on the electric slide rail 3 and the distance sensor 6. The electric slide rail 3 drives the moving plate 4 to approach the fixed plate 7, so that the reference plate 5 on the moving plate 4 approaches the distance sensor 6. When the moving plate 4 contacts the metal part, it pushes the metal part closer to the fixed plate 7. As the moving plate 4 moves, the distance between the moving plate 4 and the fixed plate 7 is equal to the length of the metal part. At this time, the electric slide rail 3 encounters resistance and stops automatically. The controller 2 reads the data measured by the distance sensor 6 to obtain the length of the metal part and complete the measurement. Then the controller 2 stores the data and controls the electric slide rail 3 to drive the moving plate 4 to reset. After the moving plate 4 resets, the electric slide rail 3 and the distance sensor 6 are turned off, and the inspection process is completed.

[0022] In the process of leveling the metal piece, the motor 10 drives the screw rod 9 to rotate, and when the screw rod 9 rotates, the push plate 11 connected with it moves along the screw rod 9, so that the push plate 11 approaches the electric sliding rail 3, and then the motor 10 is reversed to control, and the push plate 11 returns to the initial position, at this time the end face of the metal piece is parallel to the moving plate 4 and the fixed plate 7, which ensures the measurement accuracy.

[0023] As shown in Figure 3 It also includes a sponge pad 12, and the push plate 11 is connected with the sponge pad 12 at the rear side, and the sponge pad 12 can isolate the metal piece and the push plate 11, thereby protecting the metal piece and the push plate 11 from scratching each other and affecting the production quality.

[0024] As shown in Figure 1 It also includes a scale 13, and the base 1 is provided with the scale 13 at the front side, and part of the metal piece can be visually sized by the scale 13, thereby shortening the detection time.

[0025] As shown in Figure 1 It also includes an alarm lamp 14, and the controller 2 is installed with the alarm lamp 14, and the controller 2 sets the tolerance range of the metal piece, and if the measured value of the metal piece is not within this range, the controller 2 will turn on the alarm lamp 14 to remind the measurer.

[0026] As shown in Figure 1 It also includes a protective shell 15, and the electric sliding rail 3 is connected with the protective shell 15, and the protective shell 15 covers the reference plate 5 and the distance sensor 6, and the distance sensor 6 judges the distance between it and the reference plate 5 through the rays, and the protective shell 15 can block foreign objects from entering the ray part, thereby affecting the measurement data.

[0027] When measuring, the measurer first places the metal piece to be detected on the base 1, and then starts the motor 10 through the controller 2, the motor 10 drives the rotation of the screw rod 9 in the leveling assembly, and then drives the push plate 11 to move along the screw rod 9, when the sponge pad 12 at the bottom of the push plate 11 contacts and pushes the metal piece, it not only ensures that the metal piece is pushed flat to be close to the electric sliding rail 3, but also avoids direct friction damage between the metal piece and the push plate 11. After leveling, the controller 2 starts the electric sliding rail 3 and the distance sensor 6, the electric sliding rail 3 drives the moving plate 4 and the reference plate 5 at the top to move towards the fixed plate 7, until the moving plate 4 contacts the metal piece and pushes it close to the fixed plate 7, at this time the distance between the moving plate 4 and the fixed plate 7 reflects the length of the metal piece. In this process, the protective shell 15 effectively blocks the interference of foreign objects on the distance sensor 6, ensuring the accuracy of the measurement data. When the moving plate 4 stops automatically due to resistance, the controller 2 reads the data measured by the distance sensor 6 and stores the data, and then controls the electric sliding rail 3 to drive the moving plate 4 to reset through the controller 2, completing a detection process. In addition, the scale 13 on the front side of the base 1 provides the possibility of quickly visually measuring the size of part of the metal piece, and the alarm light 14 on the controller 2 can timely remind the measurer when the measured value of the metal piece exceeds the preset tolerance range.

[0028] The embodiments of the utility model are described in detail above combined with the drawings, but the utility model is not limited to the above-mentioned embodiments, within the knowledge range of the person skilled in the art, various changes can be made without departing from the purpose of the utility model.
