Description

Technical Field

[0001] The invention belongs to the technical field of bearing measurement, and in particular relates to a flexure-type bearing raceway centerline measuring device suitable for field environments. Background Art

[0002] The current method for measuring the center line of the bearing groove on the market is to use a profilometer or three-coordinate measuring machine to collect data on the inflection point section and analyze and evaluate the center position of the inner and outer ring grooves of the bearing. The measurement cycle is long and there are many measurement steps. It is impossible to quickly evaluate the quality of the workpiece on site. Manufacturing companies need to purchase profilometers or three-coordinate measuring machines to measure the workpieces in a random sampling manner. This cannot meet the company's needs for batch, fast, and high-precision measurement of manufactured workpieces on site. Summary of the invention

[0003] The present invention aims to provide a flexure-type bearing groove centerline measuring device suitable for field environments, so as to solve the technical problem that the existing bearing groove centerline measurement cannot quickly evaluate the quality of manufactured workpieces on site.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: A flexure-type bearing groove centerline measuring device suitable for field environments comprises a working base plate, four legs are installed on the bottom surface of the working base plate, a structural support plate and a working panel are installed on the working base plate, a workpiece positioning piece is installed on the working panel, and the workpiece positioning piece is used for positioning and limiting the workpiece to be measured; A balanced flexural micro-strain structure group is installed on the structural support plate, and an equal-torque probe is installed on the balanced flexural micro-strain structure group. The equal-torque probe is located above the workpiece positioning part, and a comparison table is also installed on the upper end of the structural support plate through a locking block.

[0005] Furthermore, the workpiece positioning member is a V-shaped positioning plate.

[0006] Furthermore, two positioning bolts are threadedly installed on the working panel, and two long holes are opened on the V-shaped positioning plate, and the two positioning bolts are respectively passed through the two long holes.

[0007] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention ensures the stability and durability of the entire measuring device by using basic components such as a working base plate, a support foot, a support plate and a working panel; the design of the V-shaped positioning plate enables the workpiece to be quickly and accurately positioned and limited, simplifying the measurement process; the combination of the balanced flexural micro-strain structure group and the equal torque probe can accurately capture the tiny displacement changes caused by contact, and transmit them to the comparison table for display. This method can achieve high-precision measurement without relying on complex equipment; the comparison table directly displays the measurement results, and realizes the on-site rapid and high-precision measurement of the centerline position of the inner and outer ring grooves of the bearing, which helps manufacturers to quickly assess whether the workpiece is qualified, and significantly improves the efficiency and accuracy of on-site measurement, thereby improving production efficiency and reducing scrap rate.

DETAILED DESCRIPTION

[0009] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0010] The present invention is further described in detail below in conjunction with embodiments.

[0011] like Figure 1-4 As shown, a specific embodiment 1 of a flexure-type bearing raceway centerline measuring device suitable for field environments provided by the present invention is: A flexure-type bearing groove centerline measuring device suitable for field environments includes a working base plate 1, and four supporting legs 2 are installed on the bottom surface of the working base plate 1. The four supporting legs 2 serve as supports for the device. A structural support plate 3 and a working panel 4 are installed on the working base plate 1. The working panel 4 serves as a reference surface for placing workpieces. A workpiece positioning piece is installed on the working panel 4. The workpiece positioning piece is used for positioning and limiting the workpiece to be measured; the workpiece positioning piece is a V-shaped positioning plate 5.

[0012] A balanced flexure type micro-strain structure group 6 is installed on the structural support plate 3, and an equal-torque probe 7 is installed on the balanced flexure type micro-strain structure group 6. The equal-torque probe 7 is used in combination with the balanced flexure type micro-strain structure group 6. The equal-torque probe 7 is located above the V-shaped positioning plate 5, and a comparison table 9 is also installed on the upper end of the structural support plate 3 through a locking block 8.

[0013] This embodiment adopts multi-type structural steel as the working base plate 1, and transmits the measuring position and moving stroke of the equal-torque probe 7 to the comparison table 9 through the balanced deflection type micro-strain structure group 6. The comparison table 9 displays the final measurement data, so as to determine whether the measured workpiece is qualified; wherein the structural support plate 3 is installed on the working base plate 1 to support the installation of the balanced deflection type micro-strain structure group 6, the equal-torque probe 7 is connected to the balanced deflection type micro-strain structure group 6, and the V-shaped positioning plate 5 limits the measured workpiece, and the last stop position of the measured workpiece is used as the measuring position. When the workpiece is in the measuring position, the Z-direction position of the equal-torque probe 7 generates micro-strain displacement due to contact with the workpiece. After sensing the displacement, the balanced deflection type micro-strain structure group 6 accurately transmits the displacement to the comparison table 9, and finally the actual measurement value is displayed by the comparison table 9.

[0014] This embodiment can be further optimized. Two positioning bolts 10 are threadedly installed on the working panel 4. Two long holes 11 are opened on the V-shaped positioning plate 5. The two positioning bolts 10 are respectively inserted into the two long holes 11. By loosening the positioning bolts 10, the position of the V-shaped positioning plate 5 on the working panel 4 can be adjusted. Then, the positioning bolts 10 are tightened, and the head of the positioning bolts 10 is used to squeeze the upper surface of the V-shaped positioning plate 5, thereby fixing the V-shaped positioning plate 5 on the working panel 4.
