Technical Field

[0001] The utility model relates to the field of mechanical equipment, in particular to a precision buckle mechanism. Background Art

[0002] In the current process of mechanical automation, the snap-fit ​​mechanism is a commonly used mechanism for connecting two independent devices. The existing snap-fit ​​mechanisms are mostly driven directly by a driver to snap into place / release from other independent devices. However, this snap-fit ​​mechanism directly driven by a driver is mostly used for field operations with low precision requirements. For some automation lines that require high precision, this type of snap-fit ​​mechanism has problems such as large jitter during operation resulting in low precision and poor control of the speed of snapping into place / releasing from other independent devices, which will affect the docking accuracy of the high-precision automatic line and, in more serious cases, damage the equipment that needs to be docked.

[0023] In order to better understand the purpose, structure and function of the utility model, the specific embodiment of the utility model "a precision buckle mechanism" is further described in detail below in conjunction with the accompanying drawings.

[0024] See also Figure 1 and Figure 2 In this embodiment, the precision buckle mechanism includes a base 100, a guide seat 200 and a push-pull cylinder 300 are fixedly connected to the base 100, a relatively slidable buckle 400 is provided on the guide seat 200, and a transmission member 500 is fixedly connected to the movable end of the push-pull cylinder 300; the buckle 400 includes a buckle portion 401 and a sliding portion 402 that are perpendicular to each other, and a transmission protrusion 403 is provided on the sliding portion 402, and the transmission protrusion 403 is preferably a cylinder so that the transmission protrusion 403 can be subjected to force in all directions; a sliding groove 201 is provided on the guide seat 200, and a sliding groove 201 is provided on the sliding portion 402. The shifting portion 402 is arranged in the sliding groove 201 and slides along the sliding groove 201 to drive the buckle portion 401 to slide left and right relative to the guide seat 200 to snap into position / release to separate from other independent devices; a slideway 202 is also arranged on the guide seat 200, and a transmission bevel groove 501 is arranged on the transmission member 500, and the axis of the transmission bevel groove 501 is staggered and intersected with the axis of the sliding groove 201; the transmission member 500 is slidably connected to the slideway 202, and the transmission protrusion 403 is inserted into the transmission bevel groove 501, and slides left and right relative to the guide seat 200 under the action of the force of the transmission bevel groove 501.

[0025] The specific operating principle of the precision buckle mechanism is as follows: the movable end of the push-pull cylinder 300 drives the transmission member 500 to slide linearly along the slideway 202 in the front-to-back direction, and the transmission inclined groove 501 synchronously slides linearly in the front-to-back direction. During the sliding process of the transmission inclined groove 501, the transmission protrusion 403 is subjected to a positive / reverse force perpendicular to the transmission inclined groove 501. The positive / reverse force drives the sliding part 402 to slide left and right along the sliding groove 201, thereby driving the buckle part 401 to slide left and right to engage in alignment / release from other equipment; this mechanism is realized by The transmission bevel groove 501 converts the linear force of the push-pull cylinder 300 in the front-to-back direction into an oblique force, and drives the fastener 400 to slide left and right in the sliding groove 201 in the left and right direction. By setting and changing the angle of the transmission bevel groove 501, the movement speed of the fastener 400 can be effectively controlled to prevent damage to the equipment due to poor control of the speed during engagement / release. In addition, the fastener 400 is doubly limited by the staggered and intersecting sliding grooves 201 and the transmission bevel groove 501, which reduces the polarization freedom and improves the accuracy of the fastener 400 during operation.

[0026] See also Figure 2 In some embodiments, the axis of the transmission chute 501 and the axis of the sliding groove 201 are staggered and intersect at an acute angle. In order to better achieve the buffering and transmission effects of the transmission chute 501, the angle range is preferably 10°-80°.

[0027] See also Figure 2 In this embodiment, both ends of the sliding groove 201 are openings, and both ends of the sliding part 402 can partially pass through the openings but will not be separated from the sliding groove 201. The guide seat 200 is provided with a retaining wall 203 to limit the left and right sliding stroke of the buckle part 401, and the slideway 202 is provided on the retaining wall 203. However, in some other embodiments, the sliding groove 201 can be configured to be sealed at both ends, and no additional retaining wall 203 is required. The sealing at both ends of the sliding groove 201 can limit the left and right sliding stroke of the buckle part 401, and the slideway 202 is provided at other suitable positions of the guide seat 200.

[0028] More specifically, in this embodiment, the slideway 202 is preferably arranged perpendicular to the sliding groove 201, so that it is more convenient to set the angle of the transmission inclined groove 501. Of course, in other embodiments, the slideway 202 and the sliding groove 201 can also be arranged relatively inclined according to actual needs.

[0029] See also Figure 2 In this embodiment, a through groove 204 is provided on the guide seat 200 to connect the upper and lower bottom surfaces, and the through groove 204 is parallel to the sliding groove 201; the upper and lower bottom surfaces of the sliding part 402 are both provided with transmission protrusions 403, and the upper and lower ends of the guide seat 200 are both provided with slideways 202. The transmission member 500 is U-shaped, and the two long arms of the U-shaped transmission are both provided with transmission inclined grooves 501. The transmission protrusion 403 on the lower bottom surface of the sliding part 402 passes through the through groove 204 and is clamped into the transmission inclined groove 501 of the lower arm of the transmission member 500, and the transmission protrusion 402 on the upper bottom surface of the sliding part is clamped into the transmission member The transmission inclined groove 501 of the upper arm 500, the upper arm and the lower arm of the transmission member 500 are slidably connected to the slideways 202 at the upper and lower ends of the guide seat 200 respectively; in this way, the upper and lower forces of the entire mechanism are evenly distributed, the force stability of the buckle member 400 during operation is improved, and the accuracy of the operation of the buckle mechanism is further improved; at the same time, the through groove 204 can be designed to have a smaller dimensional tolerance than the sliding groove 201, further reducing the degree of freedom of vibration of the transmission protrusion 403 on the lower bottom surface of the sliding part 402 in a direction perpendicular to the through groove 204, thereby improving the accuracy of the operation of the buckle mechanism.

[0030] More specifically, in this embodiment, a slide rail 101 is provided on the lower bottom surface of the base 100 so that the entire mechanism can slide. A transmission clamp 102 is fixedly connected to the base 100, and the transmission clamp 102 is clamped on a movable part (not shown). The moving direction of the movable part is parallel to the sliding direction of the slide rail 101 to drive the snap mechanism to slide back and forth.
