Embodiment 1

[0053] Such as figure 1 and figure 2 As shown, this embodiment proposes a mechanical limit device, including an input shaft 10, an output shaft 20, a transmission mechanism 30, a slip mechanism 40 with controllable slip direction, and a trigger mechanism for triggering the slip mechanism to slip in different directions 50, the input shaft 10, the transmission mechanism 30 and the output shaft 20 are combined to form a worm gear structure, and the input shaft 10 is connected to the output shaft 20 through the transmission mechanism 30.

[0054] combine image 3 As shown, the slip mechanism 40 of this embodiment is arranged between the input shaft 10 and the transmission mechanism 30, and the trigger mechanism 50 is associated with the output shaft 20. After the output shaft 20 outputs a predetermined amount, the trigger mechanism 50 triggers the slip mechanism 40, so that Slip occurs between the input shaft 10 and the transmission mechanism 30 .

[0055] Specifically, such ...

Embodiment 2

[0076] This embodiment also proposes another mechanical limiting device, the main difference from the first embodiment lies in the transmission structure and the triggering device.

[0077] like Figure 6 As shown, the input shaft 10, the transmission mechanism 30 and the output shaft 20 of this embodiment are combined to form a cylindrical gear transmission structure, the input shaft 10 and the output shaft 20 are arranged in parallel and side by side, the trigger mechanism 50 includes a screw sleeve 54 and a shift fork 55, the screw sleeve 54 is screwed on the output shaft 20, the shift fork 55 is fixed on the screw sleeve 54, the fork end of the shift fork 55 is clamped on the input shaft 10, and the trigger mechanism 50 follows the rotation of the output shaft 20 and moves axially to the trigger Skid mechanism 40.

[0078] The trigger mechanism of this embodiment is specifically divided into two groups, such as Figure 6 Each set of trigger mechanisms 50 shown includes a...

Embodiment 3

[0083] This embodiment proposes a mechanical limit method. A sliding mechanism with a controllable sliding direction is provided between the input shaft and the transmission mechanism. The additional trigger mechanism triggers the sliding mechanism to slide in different directions, and the The trigger mechanism is associated with the output shaft, so that after the output shaft outputs a predetermined amount, the trigger mechanism triggers the slip mechanism, so that slip occurs between the input shaft and the transmission mechanism, and the output The shaft stops rotating; after the input shaft changes the input rotation direction, the slipping mechanism stops slipping, the transmission mechanism resumes normal transmission work, and drives the output shaft to rotate. After the output shaft outputs a predetermined amount, the trigger mechanism triggers again The slipping mechanism causes slipping between the input shaft and the transmission mechanism, and the output shaft stop...

Abstract

The invention discloses a mechanical limit device and a mechanical limit method. By arranging a slip mechanism, the slip direction of which is controllable, between an input shaft and a transmission mechanism, adding a trigger mechanism to trigger the slip mechanism to slip in different directions, and carrying out action association on the trigger mechanism and an output shaft, after the output shaft outputs preset quantity, the trigger mechanism triggers the slip mechanism to enable slip to occur between the input shaft and the transmission mechanism, and the output shaft stops rotating. The device is in a pure mechanical structure design, and does not need electronic components of sensors and the like, so that power supply is not needed; the mechanical limit device adopts an idea of association arrangement of the trigger mechanism and the output shaft, thereby realizing driving the trigger mechanism to trigger the slip mechanism to realize limit by utilizing rotation of the output shaft itself; and during slip, even if the input shaft continues to input in the same rotation direction, the output shaft no longer rotates, thereby realizing fuzzy input and quantitative output.

Description

technical field [0001] The invention relates to the field of mechanical structure design, in particular to a mechanical limiting device and a mechanical limiting method. Background technique [0002] After searching, it is found that most of the traditional limit devices adopt the following types of schemes: [0003] The Chinese patent with the publication number CN203580369U discloses a limit device for the cantilever movement stroke of an automatic stamping machine. The device includes a motor installed on the mechanical platform in the housing, and the two ends of the output shaft of the motor are fixed on the platform through bearings. , the output shaft is set with a gear, the gear meshes with the rack, the rotation of the gear drives the rack to move vertically up and down, a code disc is installed on the top of the output shaft to rotate with the output shaft, and the code disc is inserted in a fixed platform In the card slot of the slot-type photoelectric sensor on ...
