Furthermore, the floating assembly comprises a first annular clamping groove arranged on the outer wall of the handle ball sleeve, a first clamping ring connected with the pressing disc and partially inserted into the first annular clamping groove, a second annular clamping groove arranged on the shell, and a second clamping ring sleeved outside the handle ball sleeve and partially inserted into the second annular clamping groove; the first clamping ring and the first annular clamping groove can relatively translate, and the second clamping ring and the second annular clamping groove can relatively translate.
Furthermore, the circumferential relative translation distance between the first clamping ring and the first annular clamping groove is 0-20 mm.
Furthermore, the outer wall of the handle ball sleeve is provided with a step structure, and when the cylinder driving shaft drives the pressing disc to move downwards to the terminal point, the step structure presses and holds the second clamping ring.
Further, the lower end part of the handle ball sleeve forms a flaring-shaped structure.
Further, the outer diameter of the operating handle is smaller than or equal to the inner diameter of the handle ball sleeve, so that the operating handle can axially slide and circumferentially rotate in the handle ball sleeve.

The large-batch off-line detection test of the manual transmission is realized by additionally arranging a gear selecting and shifting control lever on a gear selecting and shifting arm, and the following problems need to be solved: (1) after the gearbox is assembled on a production line, a spring reset force in a gearbox top cover generally keeps a gear selecting and shifting arm at an initial position (generally in a neutral state), when automatic gear selecting and shifting is carried out, positions of different gears generally move for a given distance relative to the position of the initial gear, and if the initial position of the gear shifting arm changes, gear position deviation can be caused to cause gear engaging failure, so that the initial position of the gear selecting and shifting arm of the gearbox cannot be changed by a gear selecting and shifting manipulator in the process of selecting and shifting a gear operating lever in an automatic butt joint gearbox process. (2) Due to assembly differences (including angle and axial position differences) of gear selecting and shifting arms on top covers of different gearboxes, position differences can be generated after a process gear selecting and shifting rod is installed on the gear selecting and shifting arm, and finally, position differences of handle balls at the tail end of a process control rod are generated (for an application example of the invention, the radial direction of the position differences can reach +/-20 mm), so that the gear selecting and shifting manipulator needs to have certain position deviation compensation capacity, namely, the gear selecting and shifting manipulator is used for compensating the installation position differences of the gear selecting and shifting operation rods on different gearboxes on a production line.

Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, 2 and 4, the docking device for the offline test detection of the automobile gearbox comprises a gear selecting and shifting operating rod 2 and a docking mechanism 3; the gear selecting and shifting operating rod 2 is connected with a gear selecting and shifting arm 11 of the gear box 1 to be tested and is provided with a spherical operating handle 21; the docking mechanism 3 is movable close to the operating handle 21 and includes a housing 31, a pressing plate 32 movably disposed in the housing 31, a cylinder driving shaft 33 for driving the pressing plate 32 to move in a vertical direction, a handle ball sleeve 34, and a floating assembly 35.
The handle ball sleeve 34 is hollow inside, can move along the vertical direction along with the pressing plate 32, and is movably connected with the pressing plate 32 and the shell 31 through a floating assembly 35, wherein the movable connection comprises the movement in the horizontal direction, the shaking movement deviating from the central line of the pressing plate 32, or the two activities are combined.
So that the handle ball sleeve 34 does not change the deviation of the selected shift position caused by the initial position of the manipulation handle 21 after contacting the manipulation handle 21, but moves in a direction close to the manipulation handle 21 so as to be nested outside the manipulation handle 21, i.e., is moved by the manipulation handle 21; and can continue to move down and press the housing 31 by the cylinder driving shaft 33, thereby maintaining the state of being fitted over the outer side of the manipulation handle 21.
Specifically, as shown in fig. 4, the floating assembly 35 includes a first annular groove 341 disposed on an outer wall of the handle ball sleeve 34, a first snap ring 351 connected to the pressing plate 32 and partially inserted into the first annular groove 341, a second annular groove 311 disposed on the housing 31, and a second snap ring 352 disposed outside the handle ball sleeve 34 and partially inserted into the second annular groove 311.
In this embodiment, the first snap ring 351 is a split structure, i.e. formed by splicing two semicircular rings, and the outer ring of the first snap ring 351 is fastened to the pressing plate 32 by screws, and when the cylinder driving shaft 33, i.e. the piston rod of the cylinder in this embodiment, is driven by the cylinder to drive the pressing plate 32 to move up and down, the handle ball sleeve 34 can be driven by the first snap ring 351 connected to the cylinder to move up and down together.
The housing 31 includes an end cover stop at the bottom end and a flange sleeve, and the second annular clamping groove 311 is formed by combining the two, and the outer diameter thereof is larger than that of the second snap ring 352, so that the second snap ring 352 can float by ± 20mm in any radial direction.
The first snap ring 351 and the first annular groove 341 are relatively translatable, and the second snap ring 352 and the second annular groove 311 are relatively translatable in a circumferential direction, thereby moving the handle ball sleeve 34. That is, the central axis of the handle ball sleeve 34 may overlap the centerline of the puck 32; alternatively, the first snap ring 351 and the first annular snap groove 341 may be displaced circumferentially relative to each other by a distance of 0-20mm, and the second snap ring 352 and the second annular snap groove 311 may be displaced circumferentially relative to each other by a distance of 0-20mm, offset from the centerline of the compression disc 32 but parallel thereto.
The outer wall of the handle ball sleeve 34 is provided with a step structure 342, when the cylinder driving shaft 33 drives the pressing disc 32 to move downwards to the end point, the step structure 342 presses and holds the second snap ring 352, and then the step structure is stably sleeved outside the operating handle 21.
Since the handle ball sleeve 34 is in a floating state before being pressed onto the second snap ring 352, the center position of the handle ball sleeve 34 on the horizontal projection plane can be changed with a small external force, so that the function of floating docking with the operating handle 21 is realized.
To facilitate the interface of the steering handle 21 and the handle ball sleeve 34, a flared structure 343 is formed at the lower end of the handle ball sleeve 34. The flaring-shaped structure 343 is matched with the operating handle 21 and then matched with the floating assembly 35, so that the handle ball sleeve 34 in a floating state is in self-adaptive butt joint with the operating handle 21 and is led in, the change of the initial position of the gear box selecting and shifting arm 11 caused by the change of the initial position of the operating handle 21 is avoided, the deviation of the gear selecting and shifting position caused by the change of the initial position of the gear box selecting and shifting arm 11 is avoided, and the accurate gear selecting and shifting stroke in the process of testing the gear box is ensured.
In order to allow the operating handle 21 to freely move within the handle ball sleeve 34, the outer diameter of the operating handle 21 is less than or equal to the inner diameter of the handle ball sleeve 34, so that the operating handle 21 can axially slide and circumferentially rotate within the handle ball sleeve 34 to meet the angular play requirements of the shift operating lever 2 during shifting. To reduce the influence of the mechanical fit clearance on the accuracy of the shift position control, the inner diameter of the grip ball sleeve 34 and the ball diameter of the operating grip 21 are machined to a given tolerance fit.
During detection, the docking mechanism 3 does not need to be moved to the position right above the operating handle 21, and the docking mechanism can be contacted with the operating handle 21 from the upper part, the flaring-shaped structure 343 is firstly contacted with the spherical operating handle 21, and the handle ball sleeve 34 floats under the driving of the operating handle 21, and can move horizontally or shake deviating from the central line of the pressing disc 32, so that the handle ball sleeve 34 is sleeved in the operating handle 21 without changing the initial position of the operating handle 21 to cause deviation of the gear selecting and shifting position.
When a gear shifting operation is required, the handle ball sleeve 34 moves down to the step structure 342 to press and hold the second snap ring 352, and then is stably sleeved outside the operating handle 21.
