[0022] The first sliding table 1 can adjust the shaft end of the speed reducer 5 which needs to be connected to be approximately flush with the shaft end of the driving motor 4.

[0023] After the device is installed, the end of the telescopic sleeve frame 3 which rotates around the rotating seat 2 is always sleeved with the rotating shaft of the driving motor 4, when the speed reducer 5 needs to be driven for test, the speed reducer 5 is installed on the first sliding table 1, the rotating shaft axis direction of the speed reducer 5 is parallel to the rotating shaft axis direction of the driving motor 4 when the speed reducer 5 is installed, the length of the telescopic sleeve frame 3 is adjusted, and the other end is sleeved with the rotating shaft of the speed reducer 5, so that the speed reducer 5 is quickly connected with the power end.

[0024] Since the first sliding table 1 and the rotating seat 2 have been adjusted during debugging, the first sliding table 1 is provided with a reference edge, and the speed reducer 5 is installed against the reference edge, so that the rotating shaft axis of the speed reducer 5 is parallel to the rotating shaft axis of the driving motor 4.

[0025] In the preferred embodiment, the telescopic sleeve frame 3 comprises a rhombic articulated frame 304, a set of opposite articulations of the rhombic articulated frame 304 are respectively provided with rotatable first wheel shaft 305 and second wheel shaft 306, the first wheel shaft 305 is sleeved with the first rotating wheel 301, the second wheel shaft 306 is sleeved with the second rotating wheel 302, the other set of opposite articulations of the rhombic articulated frame 304 are respectively provided with rotatable transition rotating wheel 303, each transition rotating wheel 303 respectively contacts the first rotating wheel 301 and the second rotating wheel 302, the first wheel shaft 305 is connected with the rotating shaft of the speed reducer 5, and the second wheel shaft 306 is connected with the rotating shaft of the driving motor 4.

[0026] The telescopic sleeve frame 3 is provided with two relatively telescopic housings, the rhombic articulated frame 304 and the wheels are arranged in the housings, that is, a torque transmission device.

[0027] The other set of opposite articulations of the rhombic articulated frame 304 are respectively provided with transition wheel shafts 307, and the transition rotating wheels 303 are sleeved on the transition wheel shafts 307.

[0028] The first rotating wheel 301, the first wheel shaft 305, the second rotating wheel 302, the second wheel shaft 306, the transition wheel shaft 307 and the transition rotating wheel 303 are integrally connected through key transmission or through lock nut clamping, and can rotate synchronously.

[0029] The rhombic articulated frame 304 is two, which are respectively located on two sides of the wheels, and the connection is more stable.

[0030] Since the rhombic articulated frame 304 can be articulated, the distance between the first wheel shaft 305 and the second wheel shaft 306 can be adjusted and changed, and at the same time, the rhombic articulated frame 304 can swing and adjust the orientation.

[0031] In the preferred embodiment, the outer wheel surface of the first rotating wheel 301, the second rotating wheel 302 and the transition rotating wheel 303 is provided with a friction layer.

[0032] When the friction wheel is adopted, since the friction wheel transmission itself has small noise, it is suitable for detecting the running noise of the speed reducer under low load and low speed.

[0033] The first rotating wheel 301, the second rotating wheel 302 and the transition rotating wheel 303 can also select gears, which are suitable for high-load and high-speed test projects.

[0034] Since the wheels abut against each other, power can be transmitted through friction, and the driving motor 4 can drive the speed reducer 5 to rotate.

[0035] In the preferred embodiment, the telescopic sleeve frame 3 is respectively provided with a quick connection sleeve 6 at both ends, the quick connection sleeve 6 is provided with a retractable clamping piece 609, and the clamping piece 609 clamps the rotating shaft of the driving motor 4 or the speed reducer 5.

[0036] In the preferred embodiment, the quick connecting sleeve 6 comprises a sleeve 601, one end of which is connected to the rotating shaft of the driving motor 4 or the speed reducer 5, and the other end is provided with a tapered head 602. A sliding sleeve 604 is sleeved on the sleeve 601. A plurality of clamping petals 609 are arranged on the outer side of the sliding sleeve 604 in the circumferential direction. A guide pin 608 is arranged on the sliding sleeve 604, and the sliding direction of the guide pin 608 is perpendicular to the sliding direction of the sliding sleeve 604. A wedge block 607 is also arranged, and the two ends of the guide pin 608 are connected to the clamping petals 609 and the wedge block 607, respectively. The wedge block 607 abuts against the tapered head 602. The sleeve 601 is provided with a first flange portion 603, and the sliding sleeve 604 is provided with a second flange portion 605. The first flange portion 603 and the second flange portion 605 are provided with a first spring 606 therebetween. A stop ring 615 is arranged on the second flange portion 605, and a plurality of second springs 614 are arranged on the inner wall of the stop ring 615 in the circumferential direction. Each second spring 614 abuts against each clamping petal 609.

[0037] The guide pin 608 is at least two, which prevents the wedge block 607 from rotating. After the guide pin 608 is installed, the back side of the clamping petal 609 is installed with a limiting back plate 611 to stop it.

[0038] In addition to providing support for the first spring 606, the second flange portion 605 has a larger diameter, which facilitates manual operation. Pulling the sliding sleeve 604 towards the sleeve 601 causes the wedge surface of the wedge block 607 to be pressed by the inclined surface of the tapered head 602, and the clamping petals 609 are expanded by the wedge block 607. The first spring 606 is in a compressed state.

[0039] The quick connecting sleeve 6 at one end of the telescopic sleeve frame 3 is sleeved on the rotating shaft of the driving motor 4. The second flange portion 605 is loosened, the sliding sleeve 604 moves away from the sleeve 601, the wedge block 607 moves away from the tapered head 602, and at the same time, under the action of the second spring 614, the clamping petals 609 are pressed inward and shrink to clamp the rotating shaft of the driving motor 4.

[0040] Subsequently, the telescopic sleeve frame 3 is rotated, and the quick connecting sleeve 6 at the other end of the telescopic sleeve frame 3 is sleeved and clamped on the rotating shaft of the speed reducer 5 in the same operation manner.

[0041] In the preferred embodiment, the outer wall of the sleeve 601 is provided with a guide strip 612, and the inner wall of the sliding sleeve 604 is provided with a guide groove 613. The guide strip 612 and the guide groove 613 are slidably connected.

[0042] The cooperation of the guide strip 612 and the guide groove 613 allows the sliding sleeve 604 to slide along the sleeve 601, but cannot rotate relative to the sleeve 601, effectively providing torque.

[0043] In the preferred embodiment, the inner side of the clamping petal 609 is provided with a friction portion 610.

[0044] The friction portion 610 can provide a larger friction force to prevent slipping when transmitting torque, and at the same time has a small amount of elasticity to avoid hard connection between the shafts.

[0045] In the preferred scheme, a second sliding base 7 is further provided, and the first sliding base 1 and the second sliding base 7 are arranged in perpendicular directions.

[0046] Since the adjustable length of the telescopic sleeve frame 3 is limited, for the gear reducers with large specification difference, the second sliding base 7 is needed to move the gear reducer close to the driving motor 4, so as to reach the extendable range of the telescopic sleeve frame 3.

[0047] The telescopic function of the telescopic sleeve frame 3 cannot be locked by using the adjustment function of the second sliding base 7 alone, the quick connection sleeve 6 is not easy to be connected to the upper shaft, and the second sliding base 7 is not in real-time movable state, the distance between the driving motor 4 and the gear reducer 5 is actually fixed, and over positioning is easy to occur.

[0048] The above-mentioned embodiments are only the preferred technical schemes of the present application, and should not be regarded as the limitation of the present application. The protection scope of the present application should be the technical scheme recorded in the claims, and the equivalent replacement scheme of the technical features recorded in the claims is the protection scope. That is, the equivalent replacement improvement within this range is also within the protection scope of the present application.
