Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, specifically a gear shaft coaxiality detection device. Background Technology

[0002] In the field of mechanical manufacturing, gear shafts, as core components of transmission systems, play a crucial role. The accuracy of their coaxiality—that is, whether the axes of all segments of the gear shaft remain on the same straight line—has a vital impact on the operating efficiency and stability of the entire transmission system. Gear shaft coaxiality refers to the degree to which the axes of all segments of the gear shaft remain on the same straight line during manufacturing and installation. Coaxiality is one of the important indicators for measuring the manufacturing precision and installation quality of gear shafts.

[0003] Traditional gear shaft coaxiality testing devices often suffer from the problem that the test results are easily affected by external interference, making it difficult to guarantee the accuracy and reliability of the test results.

[0004] For example, the patent specification of an existing Chinese patent (publication number: CN217504638U) discloses a gear shaft coaxiality testing device, including a base. A first fixing plate and a second fixing plate are fixedly installed on the left and right ends of the upper surface of the base, respectively. Two guide rods are fixedly installed between the first fixing plate and the second fixing plate. The two guide rods are fixedly installed on the fixing plates on the left and right sides, respectively. A clamping device is provided on the guide rods. A rotating device and a testing device are respectively provided on the clamping device. Rectangular grooves are opened on the front and rear sides of the upper surface of the base, and a sliding device is provided inside the rectangular grooves.

[0005] However, in implementing the relevant technology, the following problem was found in the gear shaft coaxiality detection device designed above: Although the device can detect the coaxiality of the gears during use, the gear shaft center position relies entirely on manual positioning during the specific operation. The shaft center position cannot be stabilized in multiple tests, which will cause the data obtained by the device to deviate and affect the detection results.

[0006] In view of this, a gear shaft coaxiality detection device is provided to overcome the above-mentioned defects. Utility Model Content

A rotatable connecting plate is installed on the side wall of the mounting plate, and a docking plate is fixedly installed on the side wall of the connecting plate. Two movable retaining plates are provided on the docking plate. A rotatable first round rod is provided in the middle of the side wall of the docking plate. A circular block is fixedly connected to one side of the first round rod, and two second round rods are fixedly installed on the other side wall. Two movable moving plates are installed on the inner wall of the docking plate near the connecting plate. A through groove is opened on the side wall of the docking plate, and the moving plates are fixedly connected to the retaining plates through the through groove. An outwardly inclined slot is opened through the outer wall of the moving plate, and the two second round rods are respectively located in the two slots.

[0009] Furthermore, a return spring is fixedly connected between the inner wall of the circular block and the outer wall of the docking plate.

[0010] Furthermore, a square groove is provided in the middle of the top surface of the base plate, and a rotatable threaded rod is installed inside the square groove. A movable plate is threadedly connected to the outer wall of the threaded rod.

[0011] Furthermore, a rotatable abutment block is installed on the side wall of the movable plate, and the abutment block is coaxially arranged with the circular block.

[0012] Furthermore, a telescopic rod is fixedly installed on the top surface of the movable plate, a connecting rod is fixedly connected to the top surface of the telescopic rod, and a test gauge is fixedly connected to one side of the connecting rod.

[0013] Furthermore, the specific number of the mounting plates is two, and two limiting rods are fixedly connected between the two mounting plates. The two limiting rods are arranged symmetrically, and the movable plate is slidably sleeved on the outer wall of the limiting rods.

[0014] Furthermore, two knobs are provided on the side wall of the mounting plate, and the two knobs are respectively fixedly connected to the threaded rod and the connecting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By setting up a circular block, a circular block and a reset spring, and setting a through groove on the outer wall of the moving plate, with the second circular rod inside the through groove, the circular block can straighten the gear shaft after being contacted by the gear shaft, preventing the gear shaft from deviating during subsequent use, and ensuring that the gear axis will not easily tilt, thus increasing the stability of the detection.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] See Figure 1-4 A gear shaft coaxiality testing device includes a base plate 1, a mounting plate 4, and a test gauge 9. A rotatable connecting plate 12 is mounted on the side wall of the mounting plate 4. A docking plate is fixedly mounted on the side wall of the connecting plate 12. Two movable retaining plates 13 are provided on the docking plate. A rotatable first round rod 16 is provided in the middle of the side wall of the docking plate. A circular block 14 is fixedly connected to one side of the first round rod 16. Two second round rods 17 are fixedly mounted on the other side wall. Two movable moving plates 18 are installed on the inner wall of the docking plate near the connecting plate 12. A through groove is opened on the side wall of the docking plate. The moving plates 18 are fixedly connected to the retaining plates 13 through the through groove. The moving plates 18 have outwardly inclined slots through the outer wall. The two second round rods 17 are respectively located in the two slots.

[0024] Furthermore, a return spring 15 is fixedly connected between the inner wall of the circular block 14 and the outer wall of the docking plate. By setting the return spring 15, the circular block 14 and the first circular rod 16 can automatically reset after being squeezed and displaced, making it convenient for the user to use the device again.

[0025] Furthermore, a square groove 2 is provided in the middle of the top surface of the base plate 1. A rotatable threaded rod 3 is installed inside the square groove 2. A movable plate 5 is threadedly connected to the outer wall of the threaded rod 3. By setting the threaded rod 3 and the movable plate 5 threadedly connected to the outer wall of the threaded rod 3, the user can drive the movable plate 5 to move by rotating the threaded rod 3.

[0026] In addition, there are two mounting plates 4. Two limiting rods 10 are fixedly connected between the two mounting plates 4. The two limiting rods 10 are symmetrically arranged. The movable plate 5 is slidably sleeved on the outer wall of the limiting rods 10. There are two mounting plates 4. A telescopic rod 7 is fixedly installed on the top surface of the movable plate 5. A connecting rod 8 is fixedly connected to the top surface of the telescopic rod 7. A test gauge 9 is fixedly connected to one side of the connecting rod 8.

[0027] By setting a limiting rod 10 and a movable plate 5 that can be slidably sleeved on the outer wall of the limiting rod 10, the movement of the movable plate 5 is made more stable and will not easily deviate. By setting a test gauge 9 connected to one side of the connecting rod 8 and the connecting rod 8 connected above the test gauge 9, the position of the test gauge 9 can be adjusted by adjusting the telescopic rod 7 during use, thereby increasing the applicability of the device.

[0028] It should be noted that a rotatable abutment block 6 is installed on the side wall of the movable plate 5, and the abutment block 6 is coaxially arranged with the circular block 14.

[0029] In practice, when using traditional testing devices to test the coaxiality of gears, users often encounter deviations in the final test results because they cannot locate the center position of the gear shaft.

[0030] In this application, the user can directly press the gear shaft against the circular block 14. After being pressed, the circular block 14 will move closer to the connecting plate 12. As the circular block 14 moves closer to the connecting plate 12, the two second circular rods 17 move simultaneously inside the two moving pieces 18. The outwardly inclined through slots on the outer walls of the two moving pieces 18 move towards the central axis of the first circular rod 16 under the drive of the second circular rods 17. One side of the moving piece 18 is fixedly connected to the arc-shaped retaining piece 13. Therefore, the two retaining pieces 13 will also be driven to move closer to each other. The two arc-shaped retaining pieces 13 can directly fix the gear shaft, preventing the gear from tilting during subsequent use.

[0031] At this point, the user only needs to turn the knob 11 connected to one side of the threaded rod 3 to make the threaded rod 3 rotate and drive the moving plate 5 and the contact block 6 to approach the gear, further fixing the gear, and then use the test gauge 9 to test the coaxiality of the gear.

[0032] By setting up a circular block 14 and a reset spring 15, and by setting a through groove through the outer wall of the moving plate 18, with the second circular rod 17 inside the through groove, the circular block 14 can straighten the gear shaft after being contacted by the gear shaft, preventing the gear shaft from deviating during subsequent use, and ensuring that the gear axis will not easily tilt, thus increasing the stability of the detection.

[0033] Working principle: The user can directly press the gear shaft against the circular block 14. After being pressed, the circular block 14 will move closer to the connecting plate 12. During the process of the circular block 14 moving closer to the connecting plate 12, the two second circular rods 17 move simultaneously inside the two moving plates 18. The two moving plates 18 have outwardly inclined through slots on their outer walls. Driven by the second circular rods 17, they move towards the central axis of the first circular rod 16. One side of the moving plate 18 is fixedly connected to the arc-shaped retaining plate 13. Therefore, the two retaining plates 13 will also be driven to move closer to each other. The two arc-shaped retaining plates 13 can directly fix the gear shaft and prevent the gear from tilting during subsequent use.

[0034] At this point, the user only needs to turn the knob 11 connected to one side of the threaded rod 3 to make the threaded rod 3 rotate and drive the moving plate 5 and the contact block 6 to approach the gear, further fixing the gear, and then use the test gauge 9 to test the coaxiality of the gear.

[0035] By setting up a circular block 14 and a reset spring 15, and by setting a through groove through the outer wall of the moving plate 18, with the second circular rod 17 inside the through groove, the circular block 14 can straighten the gear shaft after being contacted by the gear shaft, preventing the gear shaft from deviating during subsequent use, and ensuring that the gear axis will not easily tilt, thus increasing the stability of the detection.
