Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and more specifically, to a mounting device for testing engine oil pumps. Background Technology

[0002] During engine oil pump testing, the engine, oil pump, and various equipment are usually fixed to a bracket for testing. In order to ensure the comprehensiveness of the test, it is often necessary to change the parts or tools used for testing. This means that the bracket often needs to be adjusted to ensure that the parts or tools are fixed in the right position.

[0003] In existing technologies, support bars with mounting holes are typically used to fix parts or tools. The support bars are then fixed to the bracket with bolts. This means that the bolts need to be removed and installed every time the position of the support bar is adjusted, which is quite troublesome. This results in a long adjustment time for the bracket and affects testing efficiency.

[0004] Therefore, it is necessary to provide a mounting device for testing engine oil pumps to solve the above problems. Utility Model Content

[0005] Based on the aforementioned problems in the prior art, the purpose of this application is to provide a fixing device for testing engine oil pumps, thereby reducing adjustment time.

[0006] The technical solution adopted by this application to solve its technical problem is: a fixing device for testing an engine oil pump, including a test platform, a movable frame assembly is provided on the upper side of the test platform, the movable frame assembly includes a first movable frame and a second movable frame, both the first and second movable frames include a frame, movable plates are provided at the upper and lower ends of one side of the frame, clamping grooves are provided on the outer sides of the opposing surfaces of the frame and the movable plates, teeth are provided on the inner sidewalls of the clamping grooves, a plurality of support bars are provided on the inner side of the frame, clearance grooves are provided on the side of the clamping grooves of the frame near the movable plates, gear shafts are fixed at both ends of the support bars, one end of the gear shaft extends into the clamping groove through the clearance groove and is rotatably connected to a gear, the teeth on the frame and the movable plates mesh with the gears, rotating shafts are rotatably provided at the four corners of the frame, one end of each rotating shaft passes through the movable plate, and the rotating shaft is threadedly connected to the movable plate.

[0007] Furthermore, a fixed frame is fixed on the upper side of the test platform, and the second movable frame is located between the first movable frame and the fixed frame, with the frame of the first movable frame fixed to the test platform.

[0008] Furthermore, the inner sides of both the frame and the movable plate are provided with sliding grooves, and the upper and lower ends of the support bar are respectively inserted into the sliding grooves on the upper and lower sides.

[0009] Furthermore, a support shaft is connected between the rotating shaft of the first movable frame and the fixed frame. The rotating shaft of the first movable frame is fixedly connected to the support shaft, and the fixed frame is rotatably connected to the support shaft. The rotating shaft of the second movable frame is slidably sleeved on the support shaft.

[0010] Furthermore, a driver corresponding to the position of the support shaft is fixed on the fixing frame, and the output shaft of the driver is fixedly connected to the support shaft.

[0011] Furthermore, a hydraulic rod connects the frame of the second movable frame to the fixed frame.

[0012] The beneficial effects of this utility model are:

[0013] When the frame is separated from the movable plate, only the teeth and gears on the frame are engaged, and the support bar is in a movable state. The user can move the support bar along the slide groove at will to adjust the position of the support bar.

[0014] When the frame is in contact with the movable plate, the gear meshes with the teeth on both the frame and the movable plate, preventing rotation and thus fixing the support bar in a fixed state, making it unable to move. This achieves the effect of fixing the position of the support bar so that the test can be carried out.

[0015] This method allows the support bar to quickly switch between a fixed and a movable state, facilitating the adjustment of the support bar's position and increasing the speed of adjustment. Attached Figure Description

[0026] like Figure 1-2 As shown, this application provides a fixing device for testing an engine oil pump, including a test bench 1, with a fixing bracket 11 fixed on the upper side of the test bench 1.

[0027] The test bench 1 is equipped with a movable frame group 2. The movable frame group 2 includes a first movable frame 2-1 and a second movable frame 2-2. The second movable frame 2-2 is located between the first movable frame 2-1 and the fixed frame 11.

[0028] Both the first movable frame 2-1 and the second movable frame 2-2 include a frame 21. Movable plates 22 are provided at the upper and lower ends of one side of the frame 21. A clamping groove 23 is provided on the outer side of the opposite face of the frame 21 and the movable plate 22. Teeth 24 are provided on the inner sidewall of the clamping groove 23.

[0029] The inner side of the frame 21 is provided with several support bars 3. The inner sides of both the frame 21 and the movable plate 22 are provided with sliding grooves 211. The upper and lower ends of the support bars 3 are respectively inserted into the sliding grooves 211 on the upper and lower sides.

[0030] Each clamping groove 23 of the frame 21 has a clearance groove 212 on the side near the movable plate 22, which connects the bottom of the clamping groove 23 of the frame 21 to the bottom of the slide groove 211. Both ends of the support bar 3 are fixed with gear shafts 31. One end of the gear shaft 31 extends into the clamping groove 23 through the clearance groove 212 and is rotatably connected to a gear 32. The teeth 24 on the frame 21 and the movable plate 22 mesh with the gear 32.

[0031] The four corners of the frame 21 are each provided with a rotating shaft 25, one end of which passes through the movable plate 22 and is threadedly connected to the movable plate 22.

[0032] The frame 21 of the first movable frame 2-1 is fixed to the test bench 1. A support shaft 12 connects the rotation shaft 25 of the first movable frame 2-1 to the fixed frame 11. The rotation shaft 25 of the first movable frame 2-1 is fixedly connected to the support shaft 12, and the fixed frame 11 is rotatably connected to the support shaft 12. A driver 13 corresponding to the position of the support shaft 12 is fixed on the fixed frame 11. In this embodiment, the driver 13 is a motor, and the output shaft of the driver 13 is fixedly connected to the support shaft 12.

[0033] The rotating shaft 25 of the second movable frame 2-2 is slidably sleeved on the support shaft 12, and a hydraulic rod 14 is connected between the frame 21 of the second movable frame 2-2 and the fixed frame 11.

[0034] Understandably, the support bar 3 is provided with several mounting holes, so that the support block can be fixed on the support bar 3 by bolts, or directly fixed to the engine, oil pump, etc., so that the first movable frame 2-1 and the second movable frame 2-2 can support and fix all the equipment required for testing, so as to carry out the test.

[0035] In this embodiment, the cross-section of the support shaft 12 is hexagonal, and the rotation shaft 25 of the second movable frame 2-2 is sleeved on the support shaft 12, so that the second movable frame 2-2 can move along the support shaft 12 through the rotation shaft 25 of the second movable frame 2-2, and when the support shaft 12 rotates, it will also rotate the rotation shaft 25 of the second movable frame 2-2 together.

[0036] By extending and retracting the hydraulic rod 14, the second movable frame 2-2 can be moved along the support shaft 12, thereby adjusting the distance between the first movable frame 2-1 and the second movable frame 2-2.

[0037] By using an external control device, the driver 13 drives the four support shafts 12 to rotate, which in turn drives the rotating shafts 25 of the first movable frame 2-1 and the second movable frame 2-2 to rotate synchronously. At this time, the rotating shaft 25 is threadedly connected to the movable plate 22, which will cause the movable plate 22 to move away from the frame 21 by a certain distance, thereby disengaging the teeth on the movable plate 22 from the gear 32. Since only the teeth on the frame 21 are engaged with the gear 32, the support bar 3 is in a movable state, and the user can move the support bar 3 along the slide groove 211 at will to adjust the position of the support bar 3.

[0038] After the position of the support bar 3 is adjusted, the driver 13 drives all the rotating shafts 25 to rotate synchronously in reverse through the support shaft 12, so that the movable plate 22 moves closer to the frame 21 by a certain distance until the teeth on the movable plate 22 re-engage with the gear 32. At this time, the gear 32 engages with the teeth 24 on both the frame 21 and the movable plate 22 and cannot rotate, thus fixing the support bar 3 and preventing it from moving. This achieves the effect of fixing the position of the support bar 3 so that the test can be carried out.

[0039] In summary, this achieves the effect of controlling the position of the support bars 3 on the first movable frame 2-1 and the second movable frame 2-2.

[0040] This method allows the support bar 3 to quickly switch between a fixed state and a movable state, facilitating the adjustment of the support bar 3's position and increasing the speed of the position adjustment.
