[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a bearing seat bearing hole height detection fixture, including a base 1, an electric lifting bracket 101 fixedly connected to the top of the base 1, the electric telescopic bracket is divided into a bracket fixed to the base 1 and a bracket away from the base 1, an electric telescopic rod is installed inside the bracket fixed to the base 1, the top of the electric telescopic rod is connected to the bracket away from the base 1 to facilitate the up and down movement of the bracket away from the base 1, two straight grooves 102 are opened at the top of the electric lifting bracket 101, a bearing seat 6 is placed at the top of the base 1, a rotating component 2 is provided between the inside of the two straight grooves 102 and the outside of the electric lifting bracket 101, a clamping component 3 for clamping the bearing seat 6 is provided at the outer end of the rotating component 2, a measuring component 5 is provided inside the clamping component 3, and a lifting component 4 for driving the measuring component 5 to rise and fall is provided at the side end of the clamping component 3. By activating the electric lifting bracket 101, the top bracket is moved upward, which in turn moves the rotating component 2 and the clamping component 3 upward, placing the bearing seat 6 on the base 1. The electric lifting bracket 101 then descends, causing the clamping component 3 to move downward and be positioned inside the bearing hole of the bearing seat 6. After the rotating component 2 moves the clamping component 3 to limit and fix the bearing seat 6, the lifting component 4 moves the measuring component 5 downward, so that the bottom end of the measuring component 5 contacts the top end of the base 1. The data between the measuring component 5 and the end face of the bearing seat 6 is observed and recorded, thus facilitating the detection of the height of the bearing hole of the bearing seat 6. This achieves automatic measurement of the height of the bearing hole of the bearing seat 6. By automatically fixing and measuring the bearing seat 6, large measurement errors are less likely to occur. The accuracy is higher than that of manual measurement, and the measurement efficiency is also significantly improved, making the operation more convenient and faster.

[0021] As one implementation method in this embodiment, such as Figure 1 , Figure 2 and Figure 4As shown, the rotating assembly 2 includes a motor 201, which is fixedly installed on the outer side of the electric lifting bracket 101. A screw 202 is installed on the output end of the motor 201. The screw 202 is inserted into one of the straight slots 102, and the side end of the screw 202 is rotatably disposed on the inner side of one of the straight slots 102. A guide rod 203 is fixedly connected between the inner sides of the other straight slot 102. The clamping assembly 3 includes four sleeve plates 301, two of which are sleeved on the outer end of the guide rod 203, and the other two sleeve plates 301 are threaded to the outer end of the screw 202. A clamping plate 302 is fixedly connected to the bottom end of every two adjacent sleeve plates 301. A pressing plate 303 is fixedly connected to the side end of each clamping plate 302. A receiving groove is opened inside the left clamping plate 302, and a receiving groove is opened on the side end of the receiving groove. The groove 304 has a side opening 305 at the side end of the receiving groove. In practice, by starting the electric lifting bracket 101, the top bracket is moved upward, thereby moving the two clamping plates 302 upward, placing the bearing seat 6 on the base 1. The electric lifting bracket 101 then descends, causing the two clamping plates 302 to be located in the bearing hole of the bearing seat 6. At this time, by starting the motor 201, the screw 202 is rotated. Due to the limiting effect of the guide rod 203 on each sleeve plate 301, the two clamping plates 302 can be moved away from each other. At this time, the two clamping plates 302 press against the two side ends of the bearing seat 6 respectively. At this time, the pressing plate 303 can press against the top of the bearing seat 6, thereby achieving the limiting and fixing of the bearing seat 6. This facilitates the lifting assembly 4 to drive the measuring assembly 5 to detect the height of the bearing hole of the bearing seat 6, avoiding the movement of the bearing seat 6 and reducing measurement errors.

[0022] As one implementation method in this embodiment, such as Figure 3 and Figure 4As shown, the measuring component 5 includes a movable plate 501, which is inserted into the receiving groove. The movable plate 501 has a scale line 502 on its side end, located at the side end of the side opening 305. The lifting component 4 includes a side plate 401, which is fixedly connected to the side end of the left clamping plate 302. An electric push rod 402 is fixedly installed at the bottom end of the side plate 401. A connecting plate 403 is fixedly connected to the telescopic end of the electric push rod 402. The connecting plate 403 is inserted into the slot 304, and its side end is fixedly connected to the top side end of the movable plate 501. In practice, the movable plate 501 is moved downwards by activating the electric push rod 402. When the bottom end of plate 501 contacts the top end of base 1, the position of scale line 502 in the side opening 305 is observed to be flush with the end face of bearing seat 6, and the data of scale line 502 flush with the end face of bearing seat 6 is recorded. This realizes the automatic measurement of the bearing hole height of bearing seat 6. By automatically fixing and measuring bearing seat 6, it is not easy to have large measurement errors. The accuracy is higher than that of manual measurement and the measurement efficiency is also significantly improved. The operation is more convenient and faster. After the measurement is completed, the moving plate 501 is moved up and reset by electric push rod 402, and the clamping plate 302 is moved up by electric lifting bracket 101, so that bearing seat 6 can be taken out and replaced with other unmeasured bearing seat 6.

[0023] Working principle: The electric lifting bracket 101 is activated, causing the top bracket to move upwards, which in turn moves the two clamping plates 302 upwards, placing the bearing seat 6 on the base 1. This causes the electric lifting bracket 101 to descend, positioning the two clamping plates 302 within the bearing holes of the bearing seat 6. At this point, the motor 201 is activated, causing the screw 202 to rotate. Due to the guide rod 203's limiting effect on each sleeve plate 301, the two clamping plates 302 move away from each other. The two clamping plates 302 then press against the two sides of the bearing seat 6, while the pressing plate 303 presses against the top of the bearing seat 6. To achieve the limiting and fixing of the bearing housing 6, the electric push rod 402 is activated to drive the moving plate 501 to move downward. When the bottom end of the moving plate 501 contacts the top end of the base 1, the position of the scale line 502 in the side opening 305 is observed to be flush with the end face of the bearing housing 6, and the data of the scale line 502 flush with the end face of the bearing housing 6 is recorded. This achieves automatic measurement of the bearing hole height of the bearing housing 6. By automatically fixing and measuring the bearing housing 6, large measurement errors are less likely to occur. The accuracy is higher than that of manual measurement, and the measurement efficiency is also significantly improved, making the operation more convenient and faster.

[0024] After the measurement is completed, the moving plate 501 is moved upward and reset by the electric push rod 402, and the clamping plate 302 is moved upward by the electric lifting bracket 101, so that the bearing seat 6 can be taken out and replaced with other unmeasured bearing seats 6.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
