DETAILED DESCRIPTION
[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0016] Example: Figure 1-2 As shown, in this embodiment, a transmission stand with adjustable height is provided, including a transmission support frame 2 and a transmission fixing plate 8 arranged inside the transmission support frame and used to install the transmission 6, guide columns 3 are arranged on both sides of the transmission support frame, and the transmission fixing plate is detachably connected between the guide columns via a fixing structure.
[0017] In this embodiment, a driving mechanism for driving the transmission fixing plate to rise and fall is installed on the top of the transmission support frame.
[0018] The above-mentioned driving mechanism is two servo motors 1, and two lifting ears 11 are provided on the top of the transmission. The output shaft of each servo motor is connected to the corresponding lifting ear via a steel wire 12; the servo motor drives the transmission fixing plate to rise or fall via the steel wire rope, thereby bringing the transmission to an ideal position height.
[0019] The top of the transmission support frame is provided with an escape hole for the steel wire rope to extend downward.
[0020] In this embodiment, the fixing structure includes four support plates 13 respectively arranged on both sides of the transmission fixing plate, two support plates are arranged on one side, a locking plate 4 is arranged between the guide column and each support plate, and the guide column is provided with multiple positioning holes from top to bottom, one side of the locking plate is connected to the positioning hole of the guide column through the positioning pin 9, and the other side of the locking plate is connected to the support plate through the locking bolt 5.
[0021] In this embodiment, the transmission fixing plate is connected to the transmission via a transition plate 7, the inner ring of the transition plate is connected to the transmission via a plurality of inner ring bolts, and the outer ring of the transition plate is connected to the transmission fixing plate via a plurality of outer ring bolts; the inner and outer ring bolts can use the same bolts 10; it is worth noting that in order to cope with different types of transmissions, only different transition plates need to be replaced. The above-mentioned transmission fixing plate is provided with an installation space for fixing the transmission.
[0022] The inner ring portion of the transition plate is provided with a plurality of inner ring holes in the circumferential direction, and the outer ring portion of the transition plate is provided with a plurality of outer ring holes in the circumferential direction.
[0023] In this embodiment, the transmission support frame includes a crossbeam 14 and support columns 15 disposed at the four corners of the crossbeam.
[0024] In this embodiment, during installation, the height of the transmission is adjusted according to the height at which the transmission is located during the test. First, the locking bolt is loosened, the positioning pin is removed, and the servo motor is controlled to rotate forward (or reverse) so that the transmission fixing plate moves upward (or downward) under the action of the servo motor. When it is adjusted to the required position, the servo motor stops working. At this time, the positioning pin is installed and the locking bolt is tightened to fix the transmission fixing plate to the guide column.
