Description

Technical Field

[0001] This utility model belongs to the technical field of testing devices, specifically relating to a camshaft hardness testing device. Background Technology

[0002] The camshaft is a component in a piston engine. Its function is to control the opening and closing of the valves. Although the camshaft rotates at half the speed of the crankshaft in a four-stroke engine, it usually rotates at a very high speed and needs to withstand a large torque. Therefore, the design of the camshaft requires high strength and support, and its material is generally high-quality alloy steel or alloy steel.

[0003] During the machining of camshafts, a testing device is needed to test the hardness of the camshaft. However, existing testing devices require the camshaft to be clamped and fixed before testing. After the test is completed, the camshaft must be removed before the next camshaft is installed for testing. This reduces testing efficiency, delays the testing cycle, and is not convenient for practical application. Utility Model Content

[0004] To address the problems existing in the background technology, this utility model provides a camshaft hardness testing device.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

Two sets of clamping components are provided between the first mounting plate and the second mounting plate, and a transmission mechanism acting on the two sets of clamping components is also provided. A connecting member is provided between the transmission mechanism and the two sets of clamping components, and the transmission mechanism interchanges the positions of the two sets of clamping components through the connecting member. The top of the base is provided with both a detection component and a sliding component acting on the detection component.

[0007] Furthermore, the transmission mechanism includes first sprockets, four first sprockets are rotatably embedded inside the first mounting plate, the four first sprockets are rectangularly distributed and the outer surfaces of the four first sprockets are fitted with first chains; a first servo motor is fixedly mounted on the first mounting plate, and the output shaft of the first servo motor is coaxially and fixedly connected to one of the first sprockets; four second sprockets are rotatably embedded inside the second mounting plate, the four second sprockets are rectangularly distributed and the outer surfaces of the four second sprockets are fitted with second chains; a second servo motor is fixedly mounted on the second mounting plate, and the output shaft of the second servo motor is coaxially and fixedly connected to one of the second sprockets.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] like Figures 1-4As shown, the technical solution adopted by this utility model is as follows: A camshaft hardness testing device includes a base 1, with a mounting groove 16 on the top of the base 1. A first mounting plate 2 and a second mounting plate 9 are fixedly arranged in the mounting groove 16. Two sets of clamping components are provided between the first mounting plate 2 and the second mounting plate 9, and a transmission mechanism acting on the two sets of clamping components is also provided. A connecting member is provided between the transmission mechanism and the two sets of clamping components, and the transmission mechanism swaps the positions of the two sets of clamping components through the connecting member.

[0027] Furthermore, the first mounting plate 2 and the second mounting plate 9 are arranged opposite each other and are of the same specification, with the second mounting plate 9 being higher than the first mounting plate 2.

[0028] Among them, such as Figures 3-4 As shown, the transmission mechanism includes a first sprocket 8. Four first sprockets 8 are rotatably embedded in the interior of the first mounting plate 2. The four first sprockets 8 are rectangularly distributed, and a first chain 10 is sleeved on the outer surface of the four first sprockets 8. A first servo motor 12 is fixedly mounted on the first mounting plate 2, and the output shaft of the first servo motor 12 is coaxially and fixedly connected to one of the first sprockets 8.

[0029] Four second sprockets 24 are rotatably embedded inside the second mounting plate 9. The four second sprockets 24 are rectangularly distributed, and the outer surfaces of the four second sprockets 24 are fitted with second chains 25. A second servo motor 15 is fixedly mounted on the second mounting plate 9, and the output shaft of the second servo motor 15 is coaxially and fixedly connected to one of the second sprockets 24.

[0030] Furthermore, the first chain 10 and the second chain 25 are arranged opposite each other and are of the same specification, with the second chain 25 being higher than the first chain 10.

[0031] The connector includes a connecting plate 13. Two U-shaped connecting plates 13 are arranged between the first mounting plate 2 and the second mounting plate 9. A first fixing rod 22 is fixedly arranged on one side of each connecting plate 13, and a second fixing rod 19 is fixedly arranged on the other side of each connecting plate 13. The second fixing rod 19 is higher than the first fixing rod 22.

[0032] Each first fixed rod 22 is rotatably connected to the first chain 10, and each second fixed rod 19 is rotatably connected to the second chain 25. The position of the first fixed rod 22 on the first chain 10 corresponds to the position of the second fixed rod 19 on the second chain 25 (that is, the movement trajectory of the first fixed rod 22 on the first mounting plate 2 via the first chain 10 is the same as the movement trajectory of the second fixed rod 19 on the second mounting plate 9 via the second chain 25, but their heights are different).

[0033] By setting the first chain 10, the second chain 25, the first fixing rod 22, and the second fixing rod 19 at different heights, it can be ensured that the connecting plate 13 always transmits power with its opening facing upwards.

[0034] The clamping assembly includes a triangular chuck 7. Each connecting plate 13 is both fixedly mounted with the triangular chuck 7 and has a limiting sliding setting for the abutment block 3. The abutment block 3 moves closer to or further away from the triangular chuck 7. A second sliding groove 6 is provided on the base 1 for the abutment block 3 to slide.

[0035] The bottom of the connecting plate 13 is fixedly installed with the fourth servo motor 20 and the support block 21. The output shaft of the fourth servo motor 20 is fixedly installed with the first threaded rod 14. The other end of the first threaded rod 14 is rotatably connected to the support block 21. The clamping block 3 is both limited and slidably installed in the second slide groove 6 and threadedly sleeved on the outer surface of the first threaded rod 14.

[0036] The top of the base 1 is provided with both a detection component 5 and a sliding component that acts on the detection component 5. The detection component 5 is a conventional prior art and will not be described in detail in this application.

[0037] Furthermore, the area where the detection component 5 is located is called the detection area, and the position opposite to the detection area is called the replacement area.

[0038] The sliding assembly includes a third servo motor 18. The top of the base 1 is both fixedly mounted with the third servo motor 18 and has a first sliding groove 4. A second threaded rod 17 is rotatably arranged in the first sliding groove 4. The output shaft of the third servo motor 18 is coaxially and fixedly connected to one end of the second threaded rod 17.

[0039] The bottom of the detection component 5 is integrated with a slider, which is both limited and slidably disposed in the first groove 4 and threadedly sleeved on the outer surface of the second threaded rod 17.

[0040] Furthermore, both the first mounting plate 2 and the second mounting plate 9 are provided with limiting blocks 23 that act on the connecting plate 13. The limiting blocks 23 are used to press and limit the connecting plate 13 to prevent the connecting plate 13 from moving laterally when the detection component 5 performs detection operations.

[0041] Furthermore, a central control panel 11 is fixedly installed on one side of the base 1.

[0042] The central control panel 11 and the triangular chuck 7 are both conventional existing technologies, and will not be described in detail in this application.

[0043] Working principle: When in use, one end of the camshaft is fixed on the triangular chuck 7, the fourth servo motor 20 is started, and the output shaft of the fourth servo motor 20 drives the first threaded rod 14 to rotate, so that the clamping block 3 moves closer to the camshaft to clamp and limit the other end of the camshaft.

[0044] Subsequently, the first servo motor 12 and the second servo motor 15 are started simultaneously, so that the first chain 10 and the second chain 25 are driven synchronously to switch the positions of the two connecting plates 13. This allows the camshaft that has been tested to be driven to the replacement area for replacement, and the camshaft that has not been tested to be driven to the testing area for testing.

[0045] During the aforementioned switching process, the second chain 25 moves one end of the connecting plate 13 via the second fixing rod 19, while the first chain 10 moves the other end of the connecting plate 13 synchronously via the first fixing rod 22. During this process, because the second fixing rod 19 and the first fixing rod 22 are not coaxial, and the first chain 10 and the second chain 25 are of the same specification with the second chain 25 being higher than the first chain 10, the connecting plate 13 is restricted, preventing it from rotating. This causes the second fixing rod 19 and the second chain 25 to rotate relative to each other, and the first fixing rod 22 and the first chain 10 to rotate relative to each other, ensuring that the opening of the connecting plate 13 always faces upwards.

[0046] After the replacement is completed, the third servo motor 18 is started, and the output shaft of the third servo motor 18 drives the second threaded rod 17 to rotate, so as to adjust the position of the detection component 5.

[0047] Subsequently, the untested camshafts are inspected using inspection component 5. During the inspection, operators can replace the inspected camshafts in the replacement area, greatly improving inspection efficiency, reducing the inspection cycle, and making it more suitable for practical application.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
