Detailed implementation manner

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc. indicating the orientation or position relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0031] Please refer to Figures 1 to 9 , the present invention provides a mandrel placement rack for an external cylindrical grinder and a milligram energy device, including a frame 01. A first fixing frame 11 is arranged at the lower part of the frame 01, and a first storage part 02 is installed on the first fixing frame 11 for placing long-axis tapered mandrels. A second fixing frame 12 is arranged in the middle of the frame 01. A guiding square pipe 03 is horizontally installed along the short-axis direction of the frame 01. A second storage part 04 is slidably installed on the guiding square pipe 03, so that the second storage part 04 can reciprocate along the guiding square pipe 03. The second storage part 04 is specifically for placing medium and small-sized fixed mandrels and plastic mandrels.

[0032] Among them, a lower guiding wheel 31 with an axis perpendicular to the side surface of the guiding square pipe 03 is rotatably installed below one end of the guiding square pipe 03 facing the outside of the frame 01. Correspondingly, a long hole is opened on the bottom surface of the end of the guiding square pipe 03, and the outer circumferential surface of the lower guiding wheel 31 can extend into the guiding square pipe 03 along the long hole.

[0033] Among them, a side guiding wheel 32 with an axis perpendicular to the top of the guiding square pipe 03 is rotatably installed on the side surface of one end of the guiding square pipe 03 facing the outside of the frame 01. Correspondingly, a long hole is opened on the side surface of the end of the guiding square pipe 03, and the outer circumferential surface of the side guiding wheel 32 can extend into the guiding square pipe 03 along the long hole.

[0034] Among them, the second storage part 04 includes a push rod 41, a support block 42, and a tray 43; one end of the push rod 41 is slidably installed in the guide square tube 03 along the lower guide wheel 31 and the side guide wheel 32, and the other end of the push rod 41 is externally located outside the guide square tube 03 and connected to the support block 42. The tray 43 is installed on the support block 42, and a storage hole 44 is formed on the tray 43. When the push rod 41 moves along the guide square tube 03 towards the outside of the frame body 01, the tray 43 can be pulled out from the frame body 01. When placing the mandrel, the surface of the tray 43 contacts the non-use surface of the mandrel, and one end of the non-use end face of the mandrel is sunk into the storage hole 44, achieving the purpose of fixing the mandrel and effectively preventing bumps and scratches during the use of the tooling.

[0035] In one embodiment, a first guide wheel 45 with an axis perpendicular to the top of the guide square tube 03 is rotatably installed inside one end of the push rod 41 away from the support block 42. The outer circular surface of the first guide wheel 45 extends from both sides of the push rod 41, and the outer circular surface of the first guide wheel 45 is tangent to the inner wall of the guide square tube 03.

[0036] Among them, a second guide wheel 46 with an axis perpendicular to the side of the guide square tube 03 is rotatably installed at the end of the push rod 41 away from the support block 42. The outer circular surface of the second guide wheel 46 is tangent to the inner wall of the guide square tube 03.

[0037] Among them, one end of the guide square tube 03 facing the outside of the frame body 01 is higher than one end of the guide square tube 03 facing the middle of the frame body 01, making the guide square tube 03 inclined; when the mandrel is taken away, affected by the self-gravity of the second storage part 04, the push rod 41 can automatically return along the guide square tube 03.

[0038] In one embodiment, two groups of guide square tubes 03 can be arranged, and the directions of the two groups of guide square tubes 03 are opposite, enabling the push rod 41 to be pulled out towards the outside along both sides of the frame body 01, realizing that the second storage part 04 can be flexibly contracted on both sides of the frame body 01, and effectively saving the placement space.

[0039] Please refer to Figures 10 to 12 , in one embodiment, the first storage part 02 can slide out towards the outside of the frame body 01 along the short axis direction of the frame body 01.

[0040] Specifically, the first storage part 02 includes a sliding frame 21 and a support part 22; the sliding frame 21 is slidably installed on the first fixed frame 11. Correspondingly, to ensure that the sliding frame 21 can slide smoothly, a channel-shaped guide rail can be installed on the first fixed frame 11; there are two support parts 22, and the two support parts 22 are arranged side by side along the long axis direction of the frame body 01, and the two support parts 22 can move synchronously towards the middle of the frame body 01 along the top of the sliding frame 21 along the short axis direction of the frame body 01 to adjust the distance between the two support parts 22.

[0041] Specifically, a guiding groove 23 is formed at the top of the sliding frame 21 along the short axis direction of the frame body 01. A rotating rod 24 is rotatably arranged below the sliding frame 21 along the short axis direction of the frame body 01. Two guiding blocks 25 with opposite thread connection modes are installed on the rotating rod 24. After passing through the guiding groove 23, the two guiding blocks 25 are connected to the bottom of the supporting part 22. When it is necessary to adjust the distance between the two supporting parts 22, only the rotating rod 24 needs to be rotated. The rotation of the rotating rod 24 can be achieved in two ways. One is manual rotation, which can be realized by rotating a handwheel; the other can be achieved by using a variable-frequency motor as the driving source.

[0042] Of course, to ensure the stability of the sliding frame 21 during movement, legs 27 are installed at the bottom of the sliding frame 21 facing the outside, and universal wheels are installed at the lower ends of the legs 27.

[0043] Specifically, continuously distributed V-shaped positioning grooves 26 are provided at the top of the supporting part 22. The supporting part 22 is made of wood or a material with lower hardness to avoid knocking and scratching during the contact between the mandrel and the tooling frame. The two surfaces of the V-shaped positioning groove 26 support the slender cylindrical tapered mandrel, and the surface of the V-shaped block is protected with rubber skin to prevent scratching of the mandrel surface.

[0044] In one embodiment, a support plate 05 is horizontally and fixedly arranged at the top of the frame body 01. A receiving hole 51 is formed in the support plate 05, and large fixed mandrels and plastic mandrels can be placed in the receiving hole 51. Rubber pads 06 are arranged on the upper surfaces of the tray 43, the supporting part 22, and the support plate 05, which can effectively prevent knocking and scratching of the mandrel surface.

[0045] During use, for long-axis tapered mandrels, they can be placed on the first storage part 02. For large fixed mandrels and plastic mandrels, they can be placed on the support plate 05. For medium and small fixed mandrels and plastic mandrels, they can be placed on the tray 43, so as to realize multi-layer hierarchical placement management of the top layer, middle layer, and bottom layer according to the size and type of the mandrel.

[0046] The middle layer is specifically designed for placing medium and small-sized fixed mandrels and plastic mandrels: Before placing the mandrel, the push rod 41 can be pulled out along the guiding square tube 03. At this time, the lower guiding wheel 31 and the side guiding wheel 32 will form rolling supports for the transverse and longitudinal directions of the push rod 41 at the end of the guiding square tube 03 to guide and limit the push rod 41, ensuring the smooth sliding out of the push rod 41. The first guiding wheel 45 and the second guiding wheel 46 at the end of the push rod 41 can form rolling supports for the transverse and longitudinal directions of the inner wall of the guiding square tube 03, and cooperate with the lower guiding wheel 31 and the side guiding wheel 32 to achieve the four-point support and guidance of the push rod 41; When placing the mandrel, the surface of the tray 43 contacts the non-use surface of the mandrel, and one end of the non-use end face of the mandrel is sunk into the storage hole 44 to achieve the purpose of fixing the mandrel. Then, under the action of the gravity of the mandrel and the second storage part 04, the push rod 41 will automatically return to its original position.

[0047] The bottom layer is specifically designed for placing long-axis tapered mandrels: Before placing the mandrel, the sliding frame 21 can be pulled out, and then the mandrel can be placed in the V-shaped positioning groove 26. Correspondingly, the distance between the two support parts 22 can be adjusted adaptively according to the length of the mandrel to accommodate the storage of mandrels of different lengths.

[0048] When obtaining the mandrel on the middle layer, the push rod 41 can be completely pulled out along the guiding square tube 03. Due to the influence of the gravity of the mandrel and the angle formed by the inclined layout of the guiding square tube 03, the second guiding wheel 46 at the end of the push rod 41 has a greater pressure on the top inside the guiding square tube 03, and the bottom of the push rod 41 presses down on the lower guiding wheel 31. By using the second guiding wheel 46 and the lower guiding wheel 31 to form opposite acting forces on the end of the push rod 41, the force on the end of the push rod 41 is kept balanced. The first guiding wheel 45 and the side guiding wheel 32 can form a limit in the transverse direction, and cooperate with the limit formed by the second guiding wheel 46 and the lower guiding wheel 31 in the longitudinal direction to prevent the push rod 41 from sliding out of the guiding square tube 03; At this time, since the push rod 41 is fully extended, affected by the self-weight of the mandrel, the height of the end of the push rod 41 for placing the mandrel will decrease. The second guiding wheel 46 and the lower guiding wheel 31, as well as the first guiding wheel 45 and the side guiding wheel 32, will lock the end of the push rod 41 to ensure that the push rod 41 will not move when taking the mandrel. When the mandrel is taken away, the weight borne by the push rod 41 is reduced, and due to the inclination of the guiding square tube 03, the push rod 41 will automatically return to its original position.

[0049] When obtaining the mandrel on the bottom layer, the sliding frame 21 can be pulled out, and then the mandrel can be taken away.

[0050] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited by this. Those of ordinary skill in the art can understand the entire or partial processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
