Description

Technical Field

[0001] This utility model relates to the field of coaxiality detection technology, and in particular to a tooling for inspecting the coaxiality of the drive shaft on a solar thermal power generation device. Background Technology

[0002] The drive shaft in a solar thermal power generation device is a mechanical component that connects the generator to the solar tracking system. It is responsible for transmitting the power from the solar tracking system to the generator to drive the generator's rotation, thereby achieving energy conversion.

[0003] The coaxiality requirements of the drive shaft in solar thermal power generation equipment are relatively high. The existing coaxiality testing process requires two steps. First, the shaft and runout gauge are installed on the machine tool. Then, the machine tool is adjusted to test the runout of the bearing and fan blade. Each step of the measurement requires adjustment of the machine tool and movement of the tool holder.

[0004] However, moving the tool holder makes changing the rotating shaft time-consuming, which undoubtedly increases the workload and reduces work efficiency. The above-mentioned coaxiality detection process is complicated to prepare, and changing the rotating shaft is time-consuming and laborious. It is extremely inconvenient and inefficient to detect the taper and coaxiality of the shaft. In order to solve this problem, a new rotating shaft coaxiality detection fixture has been developed. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a tooling for inspecting the coaxiality of the drive shaft on a solar thermal power generation device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fixture for inspecting the coaxiality of a drive shaft on a concentrated solar power (CSP) generator includes: a coaxiality tester base, a shaft support, a dial indicator adjustment bracket, a support shaft assembly, a shaft to be tested, and a dial indicator. At least two sets of shaft support are provided, fixedly mounted on the coaxiality tester base. The shaft to be tested is positioned on the upper side of the two sets of shaft support. Two sets of support shaft assembly are provided, each mounted on one of the two sets of shaft support and rotatably connected to the shaft to be tested. The dial indicator adjustment bracket is fixedly mounted on the shaft support, and the dial indicator is fixedly mounted on the dial indicator adjustment bracket. The dial indicator is used in conjunction with the shaft to be tested.

[0008] Preferably, the coaxiality test fixture base includes: a fixing strip, a connecting frame, and a base plate. The connecting frame is fixedly installed on the fixing strip, the base plate is fixedly connected to the fixing strip through the connecting frame, and the shaft support is fixedly installed on the base plate.

[0009] Preferably, the shaft support includes a drive shaft support plate and a stiffener plate. The drive shaft support plate is fixedly installed on the base plate, and the stiffener plate is disposed on one side of the drive shaft support plate and fixedly connected to the base plate.

[0010] Preferably, the upper side of the drive shaft support plate is provided with a drive shaft rotation support area, which is used to support the rotation of the shaft being tested.

[0011] Preferably, the dial indicator adjustment support includes: a fixed base, an adjusting rod, an adjusting screw, a support block, a crossbar, and a dial indicator mounting plate. The fixed base is fixedly connected to the shaft support base. The adjusting rod is connected to the fixed base through the adjusting screw. The adjusting rod is provided with an elongated hole for installing the adjusting screw. The upper end of the adjusting rod is fixedly connected to the support block. The support block is connected to the dial indicator mounting plate through the crossbar. The dial indicator is mounted on the dial indicator mounting plate.

[0012] Preferably, the support shaft assembly includes: a small shaft, a deep groove ball bearing, a roller sleeve, a spacer, a washer, and a lock nut. The small shaft is fixedly connected to the shaft support seat by the lock nut and the washer. The deep groove ball bearing is fixedly installed on the small shaft by the roller sleeve. The spacer is fitted on the outside of the deep groove ball bearing and is rotatably connected to the shaft being tested.

[0013] The advantages of this invention are as follows: This device can adjust the position of the dial indicator by setting a dial indicator adjustment support to adapt to the measurement of coaxiality of drive shafts with different diameters. By setting a support shaft assembly, it can both support the shaft being tested and drive the rotation of the shaft being tested, thus achieving the purpose of measuring the coaxiality of the shaft being tested. This solves the problem of coaxiality testing occupying machine tool inspection and delaying machine tool efficiency, saves testing costs, and improves testing efficiency.

[0025] Example 1, combined with Figure 1 Explanation:

[0026] A tooling for inspecting the coaxiality of a drive shaft in a concentrated solar power generation device includes: a coaxiality testing fixture base 1, a shaft support seat 2, a dial indicator adjustment support 3, a support shaft assembly 4, a shaft to be tested 5, and a dial indicator 6. At least two sets of shaft support seats 2 are provided, and the two sets of shaft support seats 2 are fixedly installed on the coaxiality testing fixture base 1. The shaft to be tested 5 is disposed on the upper side of the two sets of shaft support seats 2. Two sets of support shaft assembly assemblies 4 are provided, and the two sets of support shaft assembly assemblies 4 are respectively disposed on the two sets of shaft support seats 2 and rotatably connected to the shaft to be tested 5. The dial indicator adjustment support 3 is fixedly installed on the shaft support seat 2, and the dial indicator 6 is fixedly installed on the dial indicator adjustment support 3. The dial indicator 6 is used in conjunction with the shaft to be tested 5.

[0027] By setting a coaxiality test fixture base 1 to support the shaft support seat 2, and setting the shaft support seat 2 to support the rotation of the shaft 5 being tested, by setting a dial indicator adjustment support 3 to adjust the height of the dial indicator 6 according to the diameter of the shaft 5 being tested, and by setting two sets of support shaft assembly assemblies 4, the coaxiality of different sections of the shaft 5 being tested can be inspected.

[0028] Example 2, based on Example 1, combined with... Figure 2 Explanation:

[0029] The coaxiality test fixture base 1 includes: a fixing strip 11, a connecting frame 12 and a base plate 13. The connecting frame 12 is fixedly installed on the fixing strip 11, and the base plate 13 is fixedly connected to the fixing strip 11 through the connecting frame 12. The shaft support seat 2 is fixedly installed on the base plate 13.

[0030] With this configuration, the connecting frame 12 is made of channel steel and the base plate 13 is made of steel plate. The connecting frame 12 and the base plate 13 are welded together. This not only ensures the load-bearing capacity but also reduces the weight and prevents deformation caused by the welding of steel plates, thus achieving the purpose of lightweight design.

[0031] Example 3, based on Example 2, combined with Figure 3 Explanation:

[0032] The shaft support 2 includes a drive shaft support plate 21 and a stiffener plate 22. The drive shaft support plate 21 is fixedly installed on the base plate 13, and the stiffener plate 22 is disposed on one side of the drive shaft support plate 21 and fixedly connected to the base plate 13.

[0033] The drive shaft support plate 21 has a drive shaft rotation support area 211 on its upper side, which supports the rotation of the shaft 5 being tested. The stiffening rib 22 increases the rigidity of the structure and prevents the drive shaft support plate 21 from bending or deforming under load. The fixed connection between the stiffening rib 22 and the base plate 13 improves the load-bearing capacity of the entire shaft support 2, enabling it to withstand greater working loads.

[0034] Example 4, based on Example 3, combined with Figure 4 Explanation:

[0035] The dial indicator adjustment support 3 includes: a fixed base 31, an adjustment rod 32, an adjustment screw 33, a support block 34, a crossbar 35, and a dial indicator mounting plate 36. The fixed base 31 is fixedly connected to the shaft support 2. The adjustment rod 32 is connected to the fixed base 31 through the adjustment screw 33. The adjustment rod 32 is provided with an elongated hole for installing the adjustment screw 33. The upper end of the adjustment rod 32 is fixedly connected to the support block 34. The support block 34 is connected to the dial indicator mounting plate 36 through the crossbar 35. The dial indicator 6 is mounted on the dial indicator mounting plate 36.

[0036] This configuration allows the elongated hole in the center of the adjusting rod 32 to adjust the position of the dial indicator 6, accommodating the measurement of the coaxiality of the tested shaft 5 with different diameters. The structural design of the support block 34 and the crossbar 35 provides stable support, ensuring the dial indicator 6 remains stable during measurement and reducing errors. The fixed connection between the fixed base 31 and the shaft support base 2, as well as the connection between the support block 34 and the crossbar 35 and the dial indicator mounting plate 36, makes the installation and disassembly of the entire adjusting support simple and quick.

[0037] Example 5, based on Example 4, combined with Figure 5 Explanation:

[0038] The support shaft assembly 4 includes: a small shaft 41, a deep groove ball bearing 42, a roller sleeve 43, a spacer 44, a washer 45, and a locking nut 46. The small shaft 41 is fixedly connected to the shaft support seat 2 through the locking nut 46 and the washer 45. The deep groove ball bearing 42 is fixedly installed on the small shaft 41 through the roller sleeve 43. The spacer 44 is fitted on the outside of the deep groove ball bearing 42 and is rotatably connected to the shaft 5 being tested.

[0039] This configuration, using a small shaft 41, a deep groove ball bearing 42, a roller sleeve 43, a spacer 44, a washer 45, and a locking nut 46, serves both to support the workpiece being tested and to drive its rotation, thereby achieving the function of measuring the coaxiality of the workpiece being tested.

[0040] The working principle of this utility model is as follows: When using this device, the shaft to be tested 5 is placed on the shaft support 2, so that the shaft to be tested 5 is in contact with the two sets of spacers 44. At this time, it is necessary to ensure that the coaxiality of the two sets of spacers 44 is consistent. Then, the height of the adjusting rod 32 is adjusted using the adjusting screw 33, and then the position of the dial indicator 6 is adjusted according to the shaft to be tested 5. Then, the shaft to be tested 5 is rotated and the dial indicator 6 is used to measure the coaxiality error of the shaft to be tested 5. This utility model has a reasonable structure and is easy to use. It solves the problem that coaxiality testing used to occupy machine tool inspection and delay machine tool efficiency, saves testing costs, and improves testing efficiency.
