As shown in fig. 1 to 8, an embodiment of the present invention provides a gravity slide mounting system, which includes inclined slideways 2 and a lifting mechanism 3, where at least two inclined slideways 2 are distributed at intervals in an up-down direction (i.e., Z-axis direction), and inclination directions of at least two inclined slideways 2 are opposite (the inclined slideways 2 are inclined with respect to a front-back direction, i.e., Y-axis direction); the inclined slide way 2 is provided with a damping mechanism 230, two ends of the inclined slide way 2 in the front-back direction are respectively provided with a lifting mechanism 3, each lifting mechanism 3 comprises a bearing platform 310, and the bearing platforms 310 are used for lifting and are respectively in butt joint with at least two inclined slide ways 2.

Specifically, the carrier table 310 is used to carry a tray 5 (tray 5 is shown in fig. 8 and 9), and when the carrier table 310 is raised and lowered into abutment with the inclined ramp 2, the tray 5 is used to transfer between the inclined ramp 2 and the carrier table 310. The tray 5 is transferred from the lower end of the inclined ramp 2 to the carrier table 310 so that the tray 5 is disengaged from the inclined ramp 2, or from the carrier table 310 to the upper end of the inclined ramp 2 so that the tray 5 enters the inclined ramp 2, the power for the transfer of the tray 5 being provided by gravity, or by a corresponding drive mechanism.

The two ends of the inclined sliding way 2 have a height difference in the front-rear direction (i.e. in the direction of the Y axis in the figure), when the tray 5 enters the inclined sliding way 2 from the higher end, the tray will slide along the inclined sliding way 2 to the lower end under the action of gravity, and in the process, the damping mechanism 230 contacts with the tray 5 and provides damping for the downward movement of the tray 5, so that the too fast movement speed of the tray 5 is avoided, and the movement stability of the tray 5 is improved. The structure of the damping mechanism 230 is not intended to be limiting, as it is capable of providing damping, as will be illustrated later.

As shown in fig. 1, the content of the present invention will be described in the specification by taking the example that the number of the inclined chutes 2 is two, and the two inclined chutes 2 are the workpiece feeding chute 21 and the return chute 22 from top to bottom, respectively, but it should be understood that the number of the inclined chutes 2 is not limited to two, and the workpiece feeding chute 21 may be located below the return chute 22, and the detailed description thereof is omitted here. The height of the rear end of the piece-sending slide way 21 is higher than that of the front end, the height of the rear end of the return slide way 22 is lower than that of the front end, the piece-sending slide way 21 can convey the tray 5 loaded with one or more parts from the rear end to the front end, and the return slide way 22 can convey the discharged tray 5 from the front end to the rear end. It will be appreciated that the angle of inclination of each inclined ramp 2 relative to the XY plane may be different.

Taking the workpiece feeding chute 21 as an example, the workpiece feeding chute 21 includes an inclined surface (not shown in this embodiment) formed by an obliquely arranged integral supporting plate, wherein the inclined surface has a lower height at the front end than at the rear end.

Thus, the tray 5 for carrying parts can move from a higher end to a lower end on the inclined slideway 2 by using gravity, a long-distance driving device arranged in the front-back direction can be avoided, driving faults can be reduced, energy consumption can be reduced to a certain extent, under the condition that the space in the front-back direction is enough, the inclined slideway 2 can be designed to be longer, so that more trays 5 can be cached, flexible collinear production of multiple vehicle types can be realized, the damping mechanism 230 is further used for providing damping force for the downward movement of the tray 5, the movement speed of the tray 5 is reduced, and the movement stability of the tray 5 is improved; the lifting mechanism 3 can realize the transfer of the tray 5 between different inclined slideways 2, specifically, the lifting mechanism 3 can realize the transfer of the tray 5 between different inclined slideways 2 with opposite inclined directions at the same end (for example, the tray 5 can be transferred between the feeding slideway 21 and the return slideway 22 at the front end or the rear end), and the two inclined slideways 2 with opposite inclined directions and the two lifting mechanisms 3 can jointly form a circulation loop for conveying parts by the tray 5 without manually conveying the tray 5 back. The utility model discloses can compromise the demand that reduces the energy consumption and the demand of stability in use, the reliability is high.

Specifically, the rack 1 may further include support columns 11 for supporting the cross beams 12, for example, two ends of any cross beam 12 are respectively connected with the support columns 11 and are formed with a single support frame, a plurality of support frames are distributed at intervals along the front-rear direction, the cross beams 12 of each support frame have a height difference, and the cross beams 12 are used for forming a support for the support bars 210.

The height of each cross beam 12 corresponding to the workpiece feeding slideway 21 is gradually reduced from back to front, the supporting bars 210 of the workpiece feeding slideway 21 are paved at the back front end of the corresponding cross beam 12, the height is lower than the back end, the tray 5 can thus move on the support bars 210 from the rear end to the front end under the influence of gravity, in the course of which the damping mechanism 230 provides motion damping. From front to back, the height of each cross beam 12 corresponding to the return chutes 22 is gradually reduced, the supporting bars 210 of the return chutes 22 are laid behind the corresponding cross beams 12, and the height of the front ends is higher than that of the back ends, so that the tray 5 can move on the supporting bars 210 under the action of gravity, and in the process, the damping mechanisms 230 on the return chutes 22 provide motion damping.

Thus, the size of the supporting surface of the inclined slideway 2 can be reduced, the material is saved, the overall weight of the gravity sliding table loading system is reduced, and the arrangement of the damping part 231 of the damping mechanism 230 is facilitated.

As shown in fig. 3, 5 and 8, further, the frame 1 further includes a support column 11 and a fixed rail 13, and the damping mechanism 230 further includes a movable bracket 232; the inclined slideways 2 are respectively provided with a fixed rail 13 correspondingly, the movable bracket 232 is arranged on the corresponding fixed rail 13 in a movable way along the inclined direction of the inclined slideways 2, and the damping piece 231 is arranged on the movable bracket 232;

Send a slide 21 department, two fixed rails 13 set up relatively along the left and right directions, two fixed rails 13 are connected with two sets of support post 11 that are located the left and right directions respectively, arbitrary fixed rail 13 can be connected along fore-and-aft direction distribution support post 11 with at least two, at this moment, on the left and right directions, support bar 210 is located between the fixed rail 13, movable support 232 can set up to the opening C shape frame (can refer to figure 8) towards the top, set up T shape guide slot on the fixed rail 13, the extending direction of T shape guide slot is unanimous with the incline direction of slope slide 2 (fixed rail 13 can adopt for example the aluminium alloy), C shape frame opening is towards the top, C shape frame both ends can be installed to T shape guide slot through T shape bolt, damping members 231 such as damping wheel are installed to the intermediate lamella of C shape frame. The fixed rail 13 can also be connected to the transverse beam 12 at this time.

Of course, the fixed rail 13 may also be connected only to the cross beam 12 and not to the support upright 11, for example, the fixed rail 13 may be connected to the cross beam 12 at the bottom of the cross beam 12 (this solution is not shown).

In this way, on the one hand, the interval between the damping members 231 in the front-rear direction can be conveniently adjusted or the damping members 231 can be increased or decreased according to the damping force requirement, so that the descending speed of the tray 5 on the inclined slide way 2 can be adjusted; on the other hand, the overall structural stability of the frame 1 can be enhanced by the fixed rail 13, and even a part of the longitudinal beams for connecting the supporting columns 11 and the cross beam 12 in the front-rear direction can be replaced by the fixed rail 13, so that the material consumption can be reduced.

As shown in fig. 3 and 5, optionally, the damping mechanism 230 includes at least one set of damping wheels (or rotary dampers), and the damping wheels in the same set are spaced apart along the inclined direction of the inclined ramp 2; when the number of the damping wheels is multiple groups, the multiple groups of damping wheels are distributed at intervals along the left and right directions.

Taking the workpiece feeding slideway 21 as an example, one to four groups of damping wheels are arranged at intervals along the left-right direction, at this time, one to four damping wheels are coaxially installed on the movable bracket 232, and the movable bracket 232 can simultaneously realize the interval adjustment of the plurality of damping wheels along the front-back direction when moving on the fixed rail 13. The damper wheel may be removably coupled to the moving bracket 232. The damping wheel may be of a related art, for example hydraulic pressure may be used to provide rotational damping, and will not be described in detail herein.

At this time, the tray 5 can be supported by the support rollers 220, the movement speed of the tray 5 can be reduced by the damping wheels, and the stability and reliability of the movement of the tray 5 on the inclined slide 2 are high.

As shown in fig. 3 and 4, further, the distance between the at least two sets of support rollers 220 and the edge of the inclined ramp 2 in the left-right direction is greater than a preset distance.
