[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention. Example

[0042] See attached Figure 1 , 2 As shown in , 3 and 4, a loading and unloading device in a CNC machine tool includes a base plate 3 fixedly mounted on a processing table 21 by bolts, a column 31 vertically fixedly mounted on the base plate 3, and a support plate 32 fixedly mounted on the upper end surface of the column 31 by bolts.

[0043] The upper end surface of the support plate 32 is fixedly connected with a blanking plate 4 by bolts, and a blanking trough 41 matching the shape of the product 1 is provided on the blanking plate 4. In this embodiment, in order to load two products 1 at a time, two blanking troughs 41 are provided in parallel with each other. A clamping plate 42 is fixedly installed on the upper end surface of the blanking plate 41 on both sides of the blanking trough 41 along the length direction of the blanking trough 41 by bolts, and the upper end of the clamping plate 42 is bent inwardly to facilitate clamping of the carrier 7 described below.

[0044] In this embodiment, the blanking trough 41 passes through the upper and lower end surfaces of the blanking plate 4. In order to facilitate the push of the product 1 that falls into the blanking trough 41 out of the blanking plate 4, a push-out groove (not shown in the figure) is opened on the lower end surface of the blanking plate 4 at the blanking trough 41 along the length direction of the blanking trough 41, and a pushing cylinder 51 is arranged on the lower end surface of the support plate 32. The pushing cylinder 51 can be an existing rodless cylinder structure, and a pushing plate (not shown in the figure) that can be slidably arranged in the pushing groove is fixedly installed on the moving part of the pushing cylinder 51. The pushing cylinder 51 can drive the pushing plate to push the product 1 in the blanking trough 41 out of the pushing groove and out of the blanking plate 4.

[0045] In order to position the product 1 laterally when it falls into the blanking trough 41, a side push cylinder 52 is fixedly connected to the support plate 32 on both sides of the blanking plate 4 by bolts. The side push cylinder 52 is arranged perpendicular to the length direction of the blanking trough 41, and a side push plate 53 is fixedly connected to the guide rod of the side push cylinder 52. Side push grooves (not shown in the figure) connected to the blanking trough 41 are opened on the lower end surfaces of both sides of the blanking plate 4. The side push plate 53 can be slidably arranged in the side push groove and the blanking trough 41, and under the drive of the side push cylinder 52, the product 1 in the blanking trough 41 is pushed to abut against the trough wall of the blanking trough 41.

[0046] Furthermore, in order to re-position the product 1 pushed out from the blanking chute 41 for accurate loading, a positioning plate 6 is fixedly connected to the support plate 32 by bolts, and a positioning groove 61 matching the shape of the product 1 is opened on the positioning plate 6 along the length direction of the blanking chute 41. The upper end of the positioning groove 61 passes through the upper end surface of the positioning plate 6, and one end of the positioning groove 61 passes through the side of the positioning plate 6 and is aligned with the ejection groove, that is, the pushing cylinder 51 can push the product 1 from the blanking chute 41 into the positioning groove 61.

[0047] See also Figure 5 , 6 As shown in FIG. 7 , a carrier 7 is detachably mounted on the clamping plate 42 , and the inner cavity of the carrier 7 matches the shape of the product 1 . The products stacked in the carrier 7 can fall from the outlet at the lower end of the carrier 7 into the drop chute 41 .

[0048] Specifically, in order to facilitate clamping of the product 1, the carrier 7 includes a vertical plate 1 71 and a vertical plate 2 72 which can cover each other, and slots matching the shape of the product 1 are respectively provided on the opposite end faces of the vertical plate 1 71 and the vertical plate 2 72, that is, a slot 2 721 matching the product body 11 is provided on the vertical plate 2 72, and a slot 1 711 matching the product protrusion 12 is provided on the vertical plate 1 71, thereby, the products can be horizontally stacked in the corresponding slots.

[0049] In order to facilitate the clamping of the carrier 7 on the clamping plate 42, the two outer end surfaces of the vertical plate 1 71 and the vertical plate 2 72 are respectively bolted with a clamping seat 73, and the clamping seat 73 can enter the clamping plate 42 from one end of the clamping block 42 and be fixedly clamped in the clamping plate 42.

[0050] In order to prevent the product 1 in the carrier 7 from falling from the lower opening of the carrier 7 before the carrier 7 is clamped on the clamping plate 42, a baffle 74 is slidably embedded in the lower part of the vertical plate 1. When the baffle 74 abuts against the product 1, the product cannot fall from the lower outlet of the carrier 7. When the baffle 74 is separated from the product 1, the product 1 can fall from the lower outlet of the carrier 7. The baffle 74 can have a variety of structural forms, such as the baffle 74 can be inserted into the lower part of the vertical plate 1 71 perpendicular to the vertical plate 1 71, and the upper end surface of the vertical plate 1 71 abuts against the lower end surface of the product 1 at the bottom layer in the carrier 7, thereby preventing the product 1 from falling, and when the baffle 74 is pulled out, the baffle 74 is separated from the product 1 at the bottom layer. In order to make the structure compact and realize that the baffle 74 automatically separates from the product 1 at the bottom layer when the carrier 7 is clamped on the clamping plate 42, in this embodiment, the baffle 74 has the following structure.

[0051] The baffle 74 includes a long strip baffle body 741, three stopper protrusions 742 integrally formed and fixedly connected to the end surface of the baffle body 741 facing the vertical plate 1 71, and a shifting block 743 integrally formed and fixedly connected to the end surface of the baffle body 741 facing away from the vertical plate 1 71. Three slide grooves 712 are correspondingly provided on the outer end surface of the vertical plate 1 71 at the three slots 1 711, and the three stopper protrusions 742 can be slidably disposed in the corresponding slide grooves 712 respectively. Since the product protrusion 12 is clamped in the corresponding clamping groove 711 and extends into the sliding groove 712, when the three limiting protrusions 742 slide to abut against the corresponding product protrusions 12, the limiting protrusions 742 can support the stacked products 1 to prevent the products 1 from falling from the lower opening of the carrier 7; when the three limiting protrusions 742 slide to be offset and disengaged from the corresponding product protrusions 12, the limiting protrusions 742 will not support the stacked products 1, and the products 1 can fall from the lower opening of the carrier 7.

[0052] In order to limit the baffle 74, a connecting plate 75 is fixedly connected to the outer end face of the vertical plate 71 opposite to the product protrusion 12 by bolts, and a waist-shaped adjustment hole 751 is opened on the connecting block 75. The baffle 74 is slidably embedded between the connecting plate 75 and the vertical plate 71, and the shift block 743 can be slid along the length direction of the adjustment hole 751 and penetrated into the adjustment hole 751. When the shift block 743 is shifted, the baffle 74 can be adjusted between two states: contacting with the product 1 and separating from the product 1, that is, the limiting protrusion 742 supports the stacked product 1 and the limiting protrusion 742 separates from the stacked product 1.

[0053] Adjustment grooves 713 are respectively provided along the length of the two end surfaces of the connecting plate 75 opposite to the corresponding vertical plate 71, and the baffle body 741 is slidably arranged in the adjustment grooves 713. The blanking plate 4 is vertically fixedly connected with the fixing plate 43 by bolts, and the adjustment rod 44 is horizontally fixedly embedded in the fixing plate 43. When the carrier 7 is clamped in the clamping plate 42, the adjustment rod 44 is inserted in the adjustment groove 713 and pushes the baffle body 741 to disengage the limiting protrusion 742 on the baffle body 741 from the product protrusion 12, so as to realize that the product 1 falls from the lower end outlet of the carrier 7 into the blanking groove 41.

[0054] Furthermore, in order to facilitate the placement and removal of the carrier 7 , a handle 76 is detachably provided on the upper portion of the vertical plate 1 71 and the vertical plate 2 72 .

[0055] See also Figure 3 As shown, in order to detect whether the carrier 7 has been clamped in place on the clamping plate 42, a carrier proximity sensor 45 is fixedly embedded on the fixing plate 43 in the direction of the carrier 7 during the clamping process. Figure 4 As shown, in order to detect whether the product 1 falls into the drop chute 41 , a product proximity sensor 33 is fixedly embedded on the upper end surface of the support plate 32 in the drop chute 41 .

[0056] See also Figure 8 As shown, in order to make the overall structure compact, a feeding cylinder 81 is welded or bolted vertically fixedly connected to the main shaft 23, a rotating cylinder 82 is fixedly connected to the guide rod of the feeding cylinder 81, a clamping cylinder 83 is fixedly connected to the rotating part of the rotating cylinder 82, and a clamping claw 84 is installed on the clamping cylinder 83. The feeding cylinder 81 is provided to drive the rotating cylinder 82 and the clamping cylinder 83 to move up and down, the clamping cylinder 83 is provided to clamp the product 1, and the rotating cylinder 82 is provided to facilitate the adjustment of the product orientation according to the processing jig 22 and the processing direction of the product 1.

[0057] In order to collect and place the processed products 1 , a material receiving box 9 is detachably fixedly mounted on the processing table 21 . Preferably, the material receiving box 9 is disposed on the processing table 21 between the support plate 32 and the processing jig 22 .

[0058] The working process of the embodiment of the utility model is as follows:

[0059] See also Fig. 9 As shown, the various parts of the utility model are correspondingly installed inside the CNC machine tool 8;

[0060] Automatic feeding: manually put the products 1 in a row into the slots 711 of the vertical plate 71, and move the dial block 743 to align the limiting protrusions 742 with the product protrusions 12 respectively, that is, the limiting protrusions 742 can support the product protrusions 12, and then cover the second vertical plate 72, and clamp the handle 76 to complete the clamping of the product 1 in the carrier; manually prepare two carriers 3 containing products 1, by clamping the clamping seat 73 in the clamping plate 42 from one side of the clamping plate 42, and push the carrier 7, the adjustment rod 44 is penetrated in the adjustment slot 713, so as to push the baffle plate 74 to disengage the limiting protrusions 742 from the corresponding product protrusions 12, so that the product 1 falls into the blanking slot 41, when the product proximity sensor 33 senses the product 1, the side push cylinder 52 pushes the product 1 to abut against the slot wall of the blanking slot 41, and the pushing cylinder 51 pushes the product 1 into the positioning slot 61 of the positioning plate 6;

[0061] Automatic material picking: the spindle 23 drives the picking cylinder 81, the rotating cylinder 82 and the clamping cylinder 83 to move to the top of the positioning groove 61, and clamps the product 1 through the clamping claw 84. Then the spindle 23 drives the clamped product 1 to move to the top of the processing jig 22, and adjusts the direction of the product 1 through the rotating cylinder 82, and places the product 1 on the processing jig 22, and the processing jig 22 is used to position and fix it. The processing jig 22 is a prior art and will not be described in detail here.

[0062] Automatic material collection: After the processing is completed, the spindle 23 drives the material taking cylinder 81, the rotating cylinder 82 and the clamping cylinder 83 to move to the top of the processing fixture 22 and clamp the processed product 1, and move the product 1 to the material collection box 91.
