[0045] This utility model proposes a handheld pressure bar type inspection tool for use in the inspection process of bearing sidewalls. This utility model does not limit the specific type of bearing to be inspected, but the structure of the grip block 1, pressure bar type dial indicator 3, quick inspection pressure bar group 4 and fixed probe group 5 is particularly suitable for inspecting whether the thickness of a specific area on a complex plane meets the tolerance.

[0046] In general, the handheld pressure bar type inspection tool proposed in this utility model mainly includes: a grip block 1, a pressure bar type dial indicator 3, a quick-test pressure bar assembly 4, and a fixed probe assembly 5. (See also...) Figure 1 It shows the arrangement of the holding block 1, the pressure bar type dial indicator 3, the quick test pressure bar group 4, and the fixed probe group 5.

[0047] When using the handheld pressure bar type gauge proposed in this utility model, the right hand holds the grip block 1 through the finger grip hole 12, and the right thumb presses down on the pressure block 43 to lift the measuring rod 31 in the pressure bar type dial indicator 3, creating a detection space between the detection head 32 and the fixed probe 53. The left hand places the standard part with a 0 tolerance size onto the fixed probe 53, and the right thumb leaves the pressure block 43. The measuring rod 31 falls back naturally due to gravity, and the detection head 32 presses against the other side of the standard part. The reading on the pressure bar type dial indicator 3 is checked to see if it matches the thickness value of the standard part. If it does not match, the pressure bar type dial indicator 3 needs to be calibrated to 0. After the calibration test is completed, the required detection area of ​​the bearing to be tested is pressed against the fixed probe 53 in sequence, and the pressure block 43 is continuously pressed and lifted to quickly perform the measurement. This gauge can be used to quickly measure the flat side wall, concave side wall and convex side wall of the bearing cage.

[0048] An arc-shaped groove 11 is provided on the top left side of the aforementioned holding block. A finger grip hole 12 is provided in the center of the side of the holding block away from the arc-shaped groove 11, providing a pre-set hand grip space. The detection area 2 is located at the bottom left side of the holding block 1. The detection area 2 is right-angled. A pressure rod type dial indicator 3 is inserted through one side of the arc-shaped groove 11 in the holding block. The measuring rod 31 inserted in the center of the pressure rod type dial indicator 3 has a detection head 32 at the bottom passing through the arc-shaped groove 11 and entering the detection area 2. A dial indicator mounting hole 13 is provided in the center of the bottom of the arc-shaped groove 11. A dial indicator clamping groove 14 is provided on the left end face of the holding block 1 between the arc-shaped groove 11 and the detection area 2. The dial indicator clamping groove 14 communicates with the dial indicator mounting hole 13. Bolt holes 15 are provided on the front and rear sides of the clamping groove 14 away from the dial indicator mounting hole 13. A dial indicator fixing bolt 16 is inserted into the bolt hole 15. The bottom of the dial indicator fixing bolt 16 passes through the bolt hole 15 and enters the dial indicator mounting hole 13 to abut against the pressure rod type dial indicator 3.

[0049] It should be specifically noted that when installing the lever-type dial indicator 3, the bottom detection head 32 passes through the dial indicator mounting hole 13 and abuts against the fixed probe 53. Then, the dial indicator fixing bolt 16 is tightened to limit the lever-type dial indicator 3. It should also be noted that the fixed probe 53 can be replaced. Different sizes of fixed probe 53 and detection head 32 can be replaced according to the size of the area to be tested.

[0050] The aforementioned pressure testing rod assembly is located on top of the pressure rod type dial indicator 3. The pressure testing rod assembly includes: a U-shaped block 41, a rotating rod 42, and a pressure block 43. The U-shaped block 41 is bolted to the outer casing of the top of the pressure rod type dial indicator 3 near the finger grip hole 12. The pressure block 43 is S-shaped. The rotating rod 42 passes through the top of the U-shaped block 41. The pressure block 43 is fitted in the center on the left and right sides of the rotating rod 42. A U-shaped groove 44 is opened in the center of the left side of the pressure block 43. The U-shaped groove 44 is fitted on the outside of the measuring rod 31. The top left side of the pressure block 43 abuts against the top pressure head 33 of the measuring rod 31.

[0051] It should be specifically noted that when the pressure block 43 is pressed down on the side near the finger grip hole 12, the other side of the pressure block 43 rotates upward with the rotating rod 42 as the axis of rotation, which drives the pressure head 33 to make the measuring rod 31 move upward. At this time, the pressure head 33 partially moves back and forth in the U-shaped groove 44 adaptively.

[0052] The bottom of the aforementioned fixed probe assembly 5 is inserted into the side wall of the detection area 2 away from the pressure bar type dial indicator 3. The top of the fixed probe assembly 5 is in contact with the detection head 32. The fixed probe assembly 5 includes: a fixed probe mounting hole 51, a threaded hole 52, a fixed probe 53, and a probe limiting bolt 54. The fixed probe mounting hole 51 is opened at the bottom of the side wall of the detection area 2 near the finger grip hole 12. A threaded hole 52 is opened at the bottom end of the grip block 1. The top of the threaded hole 52 communicates with the fixed probe mounting hole 51. One side of the fixed probe 53 is in contact with the detection head 32, and the other side of the fixed probe 53 is inserted into the fixed probe mounting hole 51. The probe limiting bolt 54 is inserted into the threaded hole 52, and the bottom of the probe limiting bolt 54 passes through the threaded hole 52 and enters the fixed probe mounting hole 51 to abut against the fixed probe 53.

[0053] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
