Description

Technical Field

[0001] The utility model relates to the technical field of tool storage equipment, in particular to a milling cutter storage device. Background Art

[0002] For production units that produce gear products, it is very common to use gear milling to process gear parts. Regarding gear milling, especially the rough processing of gear parts, disc gear milling cutters must be used, such as Figure 3 As shown, the disc gear milling cutter is disc-shaped as a whole, and consists of a cutter body 61 and a cylindrical pin 62. The center of the cylindrical pin 62 has an inner hole 63, and is generally suitable for rough machining of gear parts. Each gear with parameters corresponds to a dedicated disc gear milling cutter. Therefore, a large number of disc gear milling cutters (hereinafter referred to as milling cutters for ease of description) usually need to be stored in the factory at the same time.

[0003] Because the milling cutter is heavy, it is generally placed in a milling cutter box. For example, a milling cutter storage box disclosed in the prior art (patent application number: 202320314255.X) includes a box body and a drawer. When in use, the entire drawer needs to be pulled out and then a suitable disc gear milling cutter needs to be taken out. The milling cutter needs to be lifted by hand when it is taken out. It can be completely carried by manpower, or the milling cutter can be lifted to a certain height so that the inner hole of the milling cutter is exposed outside the wrapping range of the milling cutter box, and then a rope is passed through the inner hole and lifted by a crane. Finally, the entire drawer needs to be pushed to reset. The operation is cumbersome and manual operation is very laborious. The adverse effect on the operator's work efficiency is self-evident. Utility Model Content

[0004] The utility model provides a milling cutter storage device, which can solve the problem of complicated and laborious operation when taking out a disc gear milling cutter, and improve the working efficiency of operators.

[0005] This application provides the following technical solutions:

[0006] The milling cutter storage device includes a tool body and an upper tray, wherein the tool body includes a bottom plate, a center axis fixedly arranged with the center of the bottom plate as the axis, a limit portion is arranged in the middle position of the center axis, a first lifting ring for moving the tool body is arranged on the top of the center axis, a mounting hole is arranged in the center of the upper tray, and the mounting hole is clearance-matched with a position above the limit portion of the center axis, the limit portion is used to support the bottom of the upper tray, a fixing frame for vertically placing the milling cutter is evenly fixedly arranged on the upper tray and the bottom plate along the center axis, and a notch for taking out the milling cutter and a second lifting ring for moving the upper tray are arranged on the upper tray.

[0007] Beneficial effects: This solution is different from the milling cutter box commonly used in the prior art. Not only are the steps for taking out the milling cutter cumbersome and laborious, but it is also inconvenient for overlapping use and occupies a large space. The milling cutter storage device in this solution uses a multi-layer structure including a tooling body and an upper tray mounted on the tooling body, and a notch is provided on the upper tray for taking out the next layer of milling cutters from the top at any time. The upper tray can also rotate around the central axis so that the various milling cutter storage devices can be closely arranged together, maximizing the use of limited storage space, and there is no need for cumbersome retrieval and reset steps. At the same time, the retrieval and return of any milling cutter can be completed by controlling the crane, reducing the labor intensity of the operator, which is of positive significance to improving the work efficiency of the operator.

[0008] Further, as an improvement, the first lifting ring and the central axis as well as the second lifting ring and the upper tray are detachably connected.

[0009] Beneficial effect: By replacing the first lifting ring and the second lifting ring of different models, the lifting ring can be used in conjunction with different cranes, and has strong universal adaptability.

[0010] Further, as an improvement, the central shaft includes a lower shaft and an upper shaft whose diameter is smaller than that of the lower shaft, the upper shaft and the lower shaft are fixedly connected, and the limiting portion is a step formed at the connection between the upper shaft and the lower shaft.

[0011] Beneficial effects: The step formed at the connection between the upper shaft and the lower shaft is used as a limiting part for limiting and supporting the upper tray, which has a simple structure and is easy to mass produce.

[0012] Further, as an improvement, the upper tray includes a tray body, a boss fixedly arranged at the bottom of the tray body, and reinforcing ribs for reinforcing the tray body and the boss are fixedly arranged on both sides of the notch.

[0013] Beneficial effects: The design of the boss and the reinforcement ribs is conducive to improving the strength of the upper tray to enhance its ability to carry the milling cutter. At the same time, setting the reinforcement ribs on both sides of the notch can provide guidance for the process of taking the milling cutter and avoid hard contact between the milling cutter and the notch.

[0014] Further, as an improvement, the fixing frame includes two support plates arranged in parallel, and a U-shaped groove for supporting the cylindrical pin is arranged on the top of the support plate.

[0015] Beneficial effect: The two supporting plates arranged in parallel can well fix the cylindrical pins on both sides of the milling cutter through the U-shaped groove, so that the milling cutter can be stored vertically, occupying a small area, which is conducive to storing more milling cutters.

[0016] Furthermore, a mark for marking the model of the milling cutter can be detachably provided on the support plate.

[0017] Beneficial effect: The milling cutter model can be identified by marking, which facilitates accurate positioning of the milling cutter model and meets the visualization and lean management requirements of the production site. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following is further described in detail through specific implementation methods:

[0022] The marks in the drawings in the specification include: base plate 1, central axis 2, lower axis 21, upper axis 22, upper tray 3, tray body 31, boss 32, reinforcing rib 33, mounting hole 34, notch 35, first lifting ring 4, fixing frame 5, support plate 51, U-shaped groove 52, milling cutter 6, cutter body 61, cylindrical pin 62, inner hole 63, magnetic hard rubber sleeve 7, second lifting ring 8.

[0023] Embodiment 1

[0024] like Figure 1 As shown, the milling cutter storage device includes a tool body and an upper tray 3. The tool body includes a base plate 1 and a central axis 2 welded and fixed with the center of the base plate 1 as the axis.

[0025] A limiting portion for supporting the bottom of the upper tray 3 is provided at the middle position of the central shaft 2. In the present embodiment, the central shaft 2 comprises a lower shaft 21 and an upper shaft 22 having a smaller diameter than the lower shaft 21. The upper shaft 22 and the lower shaft 21 are integrally formed. The limiting portion is a step formed at the connection between the upper shaft 22 and the lower shaft 21 due to the diameter difference. A first lifting ring 4 for moving the tooling body is provided at the top of the central shaft 2. The first lifting ring 4 comprises a lifting ring body and an external threaded section integrally formed with the lifting ring body. An internal threaded hole threadedly connected to the external threaded section is provided at the top position of the central shaft 2, so as to realize a detachable connection between the first lifting ring 4 and the central shaft 2.

[0026] The upper tray 3 includes a tray body 31 and a boss 32 integrally formed with the bottom of the tray body 31. A mounting hole 34 is arranged in the center of the upper tray 3. The mounting hole 34 is a through hole that passes through the tray body 31 and the boss 32. A clearance fit is adopted between the mounting hole 34 and the upper shaft 22, so that the upper tray 3 can be sleeved on the upper shaft 22 and the upper tray 3 can be rotated with the upper shaft 22 as the axis.

[0027] Several fixing frames 5 for vertically placing the milling cutter 6 are uniformly welded and fixed around the central axis 2 on the upper tray 3 and the bottom plate 1. The fixing frame 5 includes two supporting plates 51 arranged in parallel. A U-shaped groove 52 for supporting the cylindrical pin 62 on the milling cutter 6 is arranged on the top of the supporting plate 51. The minimum spacing between the two supporting plates 51 should be greater than the spacing between the two cylindrical pins 62 on the milling cutter 6, so that the two cylindrical pins 62 of the milling cutter 6 can be hung on the U-shaped groove 52 to fix the milling cutter 6. A transparent and side-opened magnetic hard rubber sleeve 7 is pasted on the side of each supporting plate 51. A paper card with the model of the milling cutter 6 written on it can be inserted into the magnetic hard rubber sleeve 7. The notch 35 for taking out the milling cutter 6 and the second lifting ring 8 for moving the upper pallet 3, the length of the notch 35 should be greater than the total width of the milling cutter 6 so that the milling cutter 6 located on the bottom plate 1 can be taken out from the position of the notch 35, and reinforcing ribs 33 for reinforcing the pallet body 31 and the boss 32 are fixed on both sides of the notch 35, and the two ends of the reinforcing rib 33 are respectively welded and fixed to the pallet body 31 and the boss 32. In addition to the reinforcement effect, the reinforcing rib 33 also provides a guide for the process of taking out the milling cutter 6. Two second lifting rings 8 are symmetrical to each other. The second lifting ring 8 and the upper pallet 3 still use a threaded connection referring to the connection method between the first lifting ring 4 and the center axis 2.

[0028] The specific application process is as follows:

[0029] When using, first press several milling cutters 6 Figure 3 As shown in the figure, the upper tray 3 is placed on the fixing frame 5 on the bottom plate 1. After each milling cutter 6 is placed, the paper card with the corresponding model information is inserted into the magnetic hard rubber sleeve 7. Then, the upper tray 3 is dropped from above the central axis 2 by the crane and the second lifting ring 8 and is sleeved on the upper axis 22. Another batch of milling cutters 6 are placed according to the Figure 3 As shown, it is placed on the fixing frame 5 on the upper tray 3 and a paper card with corresponding model information is inserted to complete the storage of the milling cutter 6.

[0030] When the milling cutter 6 on the base plate 1 needs to be taken, the upper tray 3 is directly rotated to align the notch 35 with the milling cutter 6 that needs to be taken, and then the rope or hook of the crane is passed through the notch 35 and the inner hole 63 in turn to complete the binding, and finally the crane is controlled to lift the milling cutter 6 and detach it from the notch 35. It is worth mentioning that in actual application, there are a large number of milling cutters 6 in the factory. In order to minimize the occupied space, adjacent milling cutter storage devices need to be arranged closely together. Therefore, when taking the milling cutter 6, it is necessary to take it from the notch 35 of the upper tray 3 to avoid touching other milling cutter storage devices nearby during the taking process. At the same time, the reinforcing ribs 33 on both sides of the notch 35 provide guidance for the step of lifting the milling cutter 6 to avoid hard contact between the milling cutter 6 and the notch 35.

[0031] Embodiment 2

[0032] The difference between this embodiment and the first embodiment is that a plurality of upper trays 3 can be provided as needed to further utilize the longitudinal storage space.

[0033] The above is only an embodiment of the utility model. The utility model is not limited to the field involved in this implementation case. The common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
