Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

Referring to fig. 1-8, the utility model discloses a mold insert's conveyer for with mold insert 200 transports to the target space in, include:

a transfer assembly 100 comprising a transfer bar 110 and a carriage 120, the transfer bar 110 being rotatable and slidable with respect to the carriage 120, the transfer bar 110 being rotatable with respect to the carriage 120 to grasp or release the insert 200, the transfer bar 110 being slidable with respect to the carriage 120 to extend into or out of the target space.

It should be appreciated that in some confined target spaces, conventional clamping devices are unable to deploy the clamping arms to release the insert 200, resulting in its inability to exit the target space alone.

In this embodiment, the insert 200 is clamped or released by the rotation of the conveying rod 110, and the rotation (autorotation) of the conveying rod 110 does not increase the space occupied by the conveying rod in the target space, so that the insert 200 can be released in a narrow target space, and the conveying rod 110 can slide out of the target space after the insert 200 is released. That is, the conveying rod 110 in the present embodiment transports and releases the insert 200 in a narrow target space by rotating and sliding, and the conveying rod 110 can exit the target space.

Compared with a common clamping tool, the conveying rod 110 of the embodiment does not increase the required space in the releasing and clamping process of the insert 200, and is more beneficial to clamping, transporting and releasing the insert 200 in a narrow space.

Further, referring to fig. 3 to 5, the insert 200 has a first clamping portion 210, the conveying rod 110 has a second clamping portion 111, and the conveying rod 110 rotates relative to the conveying frame 120 to enable the second clamping portion 111 to be clamped to the first clamping portion 210 or enable the first clamping portion 210 to release the second clamping portion 111.

Specifically, when the second clamping portion 111 is clamped to the first clamping portion 210, the conveying rod 110 can drive the insert 200 to move and enter the target space; after the insert 200 is fixed and reached to the target position, the conveying rod 110 is rotated to enable the first clamping portion 210 to release the first clamping portion 210, so that the insert 200 is released by the conveying rod 110, and finally the conveying rod 110 exits from the target space.

Further, the first clamping portion 210 is provided with a groove, the groove has a first cross section and a second cross section, the second cross section is located on the side of the first cross section close to the bottom surface 213 of the groove, and the width of the first cross section is smaller than that of the second cross section;

the second clamping portion 111 has a minimum width smaller than the width of the first cross section and a maximum width greater than the width of the first cross section.

Specifically, the minimum width of the second clamping portion 111 is smaller than the width of the first cross section, and the conveying rod 110 is rotated by a certain angle, so that the projection of the second clamping portion 111 in the width direction of the first cross section is the minimum width, and the conveying rod 110 can pass through the first cross section; the maximum width of the second clamping portion 111 is greater than the width of the first cross section, and the conveying rod 110 can rotate a certain angle after passing through the first cross section, so that the projection of the second clamping portion 111 in the width direction of the first cross section is the maximum width, and the second clamping portion 111 cannot retreat from the first cross section. That is, the first clamping portion 210 and the second clamping portion 111 can be coupled and decoupled by the rotation of the feeding rod 110.

The reason why the width of the first cross section is smaller than that of the second cross section is to ensure that the conveying rod 110 can rotate a certain angle when the second clamping portion 111 passes through the first cross section and is located at the position of the second cross section, so that the second clamping portion 111 can be locked in the first clamping portion 210.

In summary, in the present embodiment, by rotating the conveying rod 110, the projection (i.e., the maximum width and the minimum width) of the second clamping portion 111 in the width direction of the first clamping portion 210 is changed, so that the second clamping portion 111 can pass through or cannot pass through the first cross section, thereby clamping and releasing the insert 200 by the conveying rod 110.

It should be noted that the conveying device conveys the insert 200 to the inside of the target workpiece 400, and the target space may be understood as a narrow space formed inside the target workpiece 400, such as a hole, a channel, a slot, etc. formed in the inner space of a hollow tube or other objects.

Specifically, the maximum width is set to be smaller than the width of the second cross section, so that the second clamping portion 111 can rotate freely at any angle after passing through the first cross section and reaching the second cross section, the second clamping portion 111 cannot be clamped at the second cross section and cannot exit, the situation that the first clamping portion 210 and the second clamping portion 111 cannot be separated is further avoided, and the insert 200 can be released by the conveying rod 110.

Furthermore, one end of each of the two side surfaces 212 of the groove, which is far away from the bottom surface 213 of the groove, is bent inward to form a hook 211, and the distance between the two hooks 211 is smaller than the distance between the two side surfaces 212.

It will be appreciated that the first section is at the location of the two hooks 211 and the second section is at the location of the two sides 212 of the groove; when the width of the second clamping portion 111 is greater than the distance between the two hooks 211, the second clamping portion 111 cannot be withdrawn from between the two hooks 211, so that the first clamping portion 210 and the second clamping portion 111 are connected; in contrast, when the width of the second clamping portion 111 is smaller than the distance between the two hooks 211, the second clamping portion 111 may pass between the two hooks 211, and the separation of the first clamping portion 210 and the second clamping portion 111 is achieved.

Further, the cross section of the second clamping portion 111 is rectangular parallelepiped.

It should be noted that, the second clamping portion 111 disposed in a rectangular parallelepiped includes two longer sides (maximum width) and two shorter sides (minimum width), when the projection of the second clamping portion 111 in the width direction of the first clamping portion 210 is a longer side, the second clamping portion 111 cannot pass through the first cross section; when the projection of the second clamping portion 111 in the width direction of the first clamping portion 210 is a shorter side, the second clamping portion 111 may pass through the first cross section, so that the first clamping portion 210 and the second clamping portion 111 are separated, and clamping and releasing of the insert 200 by the conveying rod 110 are also achieved.

Further, please refer to fig. 1, fig. 6 to fig. 8, which further includes:

a first positioning assembly 300 interfacing with the transfer assembly 100 and positioning an initial position of the insert 200;

and a second positioning assembly provided on the conveying assembly 100 and used for adjusting the maximum sliding distance of the conveying rod 110 relative to the conveying rack 120.

Understandably, the small target space makes positioning of the insert 200 within the target space difficult, which results in the inability to position and secure the insert 200 after delivery.

In this embodiment, the initial position of the insert 200 is determined by the first positioning assembly 300 and the distance of movement of the insert 200 is determined by the second positioning assembly. Since the initial position of the insert 200 is determined, the position of the insert 200 between the determined distances of movement is also determined, thereby achieving positioning of the insert 200 within the target space.

In this embodiment, the distance from the hook 211 to the bottom surface 213 of the groove is equal to the thickness of the first clamping portion 210, so that there is no space for front and rear loosening after the first clamping portion 210 and the second clamping portion 111 are connected, thereby facilitating accurate positioning of the insert 200.

Further, the first positioning component 300 includes: the bearing table 310 is provided with a positioning piece 311, and the positioning piece 311 can slide relative to the bearing table 310;

the insert 200 is movably mounted on the receiving platform 310, the insert 200 has a positioning portion 220, the positioning member 311 slides relative to the receiving platform 310 to extend into or slide out of the positioning portion 220, and the positioning member 311 slides into the positioning portion 220 to limit the movement of the insert 200 relative to the receiving platform 310.

Also included is a hold down block 500 disposed on a side of the insert 200 remote from the receiving station 310, the hold down block 500 moving toward or away from the insert 200 to hold down or release the insert 200.

Specifically, the insert 200 is placed on the receiving table 310, and the positioning member 311 extends into the positioning portion 220 to limit the movement of the insert 200 on the receiving table 310, so as to position the insert 200 in the plane direction of the receiving table 310; and then the insert 200 is pressed by the pressing block 500, so that the insert 200 is positioned in the direction vertical to the plane of the receiving table 310, and the insert 200 is positioned in a three-dimensional space by the positioning part 311, the positioning part 220 and the pressing block 500, so that the initial position of the insert 200 is more accurately positioned. For example, assuming that the plane of the receiving table 310 is a horizontal plane, the positioning member 311 and the positioning portion 220 may limit the movement of the insert 200 in the horizontal direction, and the pressing block 500 may limit the movement of the insert 200 in the vertical direction, thereby positioning the insert 200 in a three-dimensional space.

Further, referring to fig. 1, the second positioning assembly includes: a first positioning block 600 disposed on the conveying assembly 100; a second positioning block 610 disposed on the receiving table 310; the first positioning block 600 abuts against the second positioning block 610 to limit the sliding of the conveying rod 110 in the direction toward the target space.

It can be understood that when the first positioning block 600 abuts against the second positioning block 610, the slide of the feeding rod 110 in the direction toward the target space is only limited, and the slide in the opposite direction is not limited, and the feeding rod 110 can still be retracted after releasing the insert 200. That is, the primary function of the first positioning block 600 and the second positioning block 610 is to determine the farthest distance that the insert 200 slides from the initial position, so as to achieve accurate positioning of the insert 200 in the target space.

Further, referring to fig. 2, the device further includes a connecting frame 130, the connecting frame 130 is slidably connected to the conveying frame 120, the conveying rod 110 is rotatably disposed on the connecting frame 130, and the first positioning block 600 is fixedly connected to the connecting frame 130.

Further, in this embodiment, driving cylinders for driving the conveying rod 110 to rotate, driving the conveying rod 110 to slide, driving the positioning element 311 to extend and retract, and driving the pressing block 500 to move are respectively provided.

The positions of the first positioning block 600 and the second positioning block 610 in the sliding direction of the conveying rod 110 are adjustable, that is, the maximum distance that the insert 200 can move can be adjusted, and finally, the adjustment of the position of the insert 200 in the target space is realized.
