Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Referring to fig. 1-3, a positioning and fixing device for a gantry type manipulator comprises a support guide rail 1, wherein a support seat 2 is connected to the inner wall of the support guide rail 1 in a sliding manner, specifically, guide grooves 12 are formed in two opposite inner walls of the support guide rail 1, guide blocks 13 are connected to the guide grooves 12 in a sliding manner, and the guide blocks 13 are fixedly connected to the side walls of the support seat 2.

Supporting seat 2 runs through and is equipped with threaded rod 4, and is further, and the screw rod hole has been seted up to the upper end of supporting seat 2, and threaded rod 4 passes the screw rod hole, and the aperture in screw rod hole is greater than the diameter of threaded rod 4. The upper end of supporting seat 2 is rotated and is connected with adjusting nut 3, and threaded rod 4 and threaded connection are in adjusting nut 3, it needs to explain that, threaded rod 4 passes the screw rod hole that is bigger than it, consequently can not take place the motion with supporting seat 2, and adjusting nut 3 accessible bearing is rotated with supporting seat 2 when the installation simultaneously and is connected, and concrete mounting means is the mature technique of current machine parts installation complex, so do not describe in detail.

Two spouts 9 have been seted up to the lower extreme fixedly connected with manipulator body 5 of threaded rod 4, the lateral wall of supporting seat 2, and two spouts 9 set up along 4 symmetries of threaded rod, rotate on the threaded rod 4 and be connected with two bracing pieces 6, and is concrete, and two bracing pieces 6 also set up along 4 symmetries of threaded rod. The rotary connection of the support rod 6 to the threaded rod 4 is located on the polished rod portion of the threaded rod 4 to prevent interference with the own movement of the threaded rod 4. A limiting device for limiting the supporting rod 6 is arranged in the sliding groove 9.

Stop device includes the stopper 10 of sliding connection in spout 9, and the one end that threaded rod 4 was kept away from to bracing piece 6 rotates and connects on the lateral wall of stopper 10, and the rotation junction of bracing piece 6 and stopper 10 is located the central point of stopper 10 and puts the department. Spacing hole 11 has been seted up to the upper end of stopper 10, and a plurality of through-holes 7 have been seted up to the upper end of supporting seat 2, wherein are equipped with spacer pin 8 in the through-hole 7, and the lower extreme of spacer pin 8 extends to spacing downthehole 11, and a plurality of through-holes 7 are along 4 symmetric distribution of threaded rod, and the through-hole 7 equipartition interval distribution of threaded rod 4 both sides. It should be noted that, through setting up a plurality of equidistant through-holes 7, can all pass through-hole 7 with spacer pin 8 and insert spacing hole 11 when stopper 10 removes to different positions to accomplish the rigidity of stopper 10, bracing piece 6 and threaded rod 4, fix with the manipulator body 5 of different extension lengths in order to make things convenient for.

When using this device, when the extension length of manipulator body 5 needs to be adjusted, can extract the spacer pin 8 in the through-hole 7 earlier, rotatory adjusting nut 3 this moment, can make threaded connection take place to reciprocate in adjusting nut 3 threaded rod 4, and make manipulator body 5 synchronous motion, so can adjust the extension length of manipulator body 5, adjust the back that finishes, loosen adjusting nut 3, threaded rod 4 gets into the auto-lock under the auto-lock of screw at this moment, therefore can not take place to remove, then bracing piece 6 and stopper 10's position also relatively fixed.

Then, the limit pin 8 is inserted into the corresponding through hole 7, and the limit pin 8 enters the limit hole 11, so that the limit block 10 can be locked, and the support rod 6 and the threaded rod 4 can be fixed. When manipulator body 5 snatchs the heavy object, the downward pulling force that manipulator body 5 receives most will turn into along the component force of 6 directions of two bracing pieces, reduces 4 threaded rod screw tracks atress greatly, avoids causing the damage to the screw thread tooth, prevents that the manipulator is impaired and the accident appears.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
