Description

Technical Field

[0001] This utility model relates to the technical field of milling cutter storage racks, specifically to a height-adjustable milling cutter storage rack. Background Technology

[0002] In the manufacturing process of end mills, the cutter storage rack is a key tooling for temporary storage and turnover between processes. Currently, the common cutter storage racks on the market are usually simple in structure. Their basic form is a support plate with multiple rows of storage holes. When placing the cutter, the cutter can only be inserted directly into the storage hole with its bottom end face. This support method only provides single-point support for the cutter at the bottom.

[0003] For shorter end mills, existing support structures can meet storage requirements. However, for end mills with longer shanks, the upper part of the shank is completely unsupported and suspended during storage. Because end mills have a certain weight, this heavy-headed structure makes them prone to tilting, wobbling, or even bending during storage due to their own weight or minor external forces. This directly affects the straightness of the end mill, severely impacting final machining accuracy and product quality, leading to quality losses for the company.

[0004] To address these issues, we propose a height-adjustable milling cutter storage rack. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a height-adjustable milling cutter storage rack to meet the need for reliable storage of milling cutters of different lengths.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a height-adjustable milling cutter storage rack, comprising a bottom support plate, wherein multiple vertically arranged guide rods are fixedly connected to the top periphery of the bottom support plate, and a milling cutter shank support plate is arranged parallel above the bottom support plate, wherein the milling cutter shank support plate is provided with through holes that slide with the guide rods; the milling cutter shank support plate is provided with multiple rows of through milling cutter holes, and the bottom support plate is provided with placement holes at the positions corresponding to the milling cutter holes; The milling cutter storage rack further includes an adjustment assembly for driving the milling cutter shank support plate to move up and down along the guide rod, the adjustment assembly including: The connector includes a base fixed to the bottom support plate and a mounting part rotatably connected to the base; The threaded rod has its lower end threadedly connected to the mounting part, and its upper end passing through a light hole opened on the milling cutter rod support plate, and is threadedly connected to the upper limit member and the lower limit member; the upper limit member and the lower limit member are respectively snapped into the upper and lower sides of the milling cutter rod support plate; A handwheel is fixedly mounted on the top of the threaded rod. By rotating the handwheel, the threaded rod is driven to rotate, which in turn drives the upper and lower limit components to move, causing the milling cutter rod support plate to rise and fall along the guide rod to a designated position.

[0007] Furthermore, a spring is sleeved on the outside of the guide rod, and the spring is located between the bottom support plate and the milling cutter rod support plate.

[0008] Furthermore, the upper and lower limit members are respectively provided with multiple limiting grooves circumferentially along the threaded holes on the surface of the milling cutter shank support plate; On the upper and lower sides of the milling cutter shank support plate, there are respectively circumferential limiting protrusions around the light hole, which engage with the limiting groove, and the limiting protrusions and the milling cutter shank support plate are integrally formed. When the upper limit member limits the milling cutter rod support plate, or the lower limit member limits the milling cutter rod support plate, the limiting protrusion and the limiting groove engage with each other.

[0009] Furthermore, the limiting protrusion is a wedge-shaped protrusion, and the limiting groove is a wedge-shaped groove that mates with the wedge-shaped protrusion.

[0010] Furthermore, the inclined end of the limiting protrusion is provided in a rounded arc shape.

[0011] Furthermore, a soft cushioning pad is fixedly connected to the upper surface of the bottom support plate, and the placement hole is set on the soft cushioning pad.

[0012] Furthermore, the soft cushioning pad is one of a silicone pad, a rubber pad, or a sponge pad.

[0013] Furthermore, the milling cutter hole is provided with an elastic buffer ring, which is in the shape of an "I" and has a through-center, with its upper and lower ends respectively engaged with the upper and lower sides of the milling cutter hole.

[0014] Furthermore, the elastic buffer ring is either a silicone buffer ring or a rubber buffer ring.

[0015] Compared with existing technologies, the above technical solution has the following advantages: simple structure, convenient control, and can adapt to the storage needs of milling cutters of different lengths. It provides good support for the middle part of the milling cutter, prevents the milling cutter from deforming due to bottom support alone, effectively ensures the quality of the milling cutter products, and has great value for promotion and application.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0020] To address the problems existing in the prior art, this utility model provides a height-adjustable milling cutter storage rack. The following is a detailed description of this utility model with reference to the accompanying drawings. Example 1

[0021] See Figures 1-5As shown, the technical solution adopted in this specific embodiment is: a height-adjustable milling cutter storage rack, mainly composed of a bottom support plate 1, a milling cutter shank support plate 3, guide rods 2, and an adjustment mechanism. Specifically, the bottom support plate 1 serves as the basic support component of the entire storage rack, with multiple vertically arranged guide rods 2 distributed along its top edge. Springs 21 are fitted onto the outside of each guide rod 2, and the springs 21 are confined within the space between the bottom support plate 1 and the milling cutter shank support plate 3. A milling cutter shank support plate 3 is arranged parallel to the bottom support plate 1, and this milling cutter shank support plate 3 has through holes 31 matching the number of guide rods 2, allowing the milling cutter shank support plate 3 to slide up and down along the guide rods 2. Multiple rows of neatly arranged and penetrating milling cutter holes 32 are machined on the milling cutter shank support plate 3 for placing the milling cutter shank. Corresponding placement holes 11 are also provided at corresponding positions on the bottom support plate 1 to ensure that the milling cutters can be stored vertically and stably.

[0022] It should be specifically noted that the core of this milling cutter storage rack lies in its height adjustment function, which is achieved through the adjustment component 4. This adjustment component 4 is used to drive the milling cutter shank support plate 3 to rise and fall along the guide rod 2. The adjustment component 4 mainly includes a connector 41, a threaded rod 42, and a handwheel 43. Specifically, the connector 41 is installed on the bottom support plate 1. The connector 41 includes a base 411 fixed to the bottom support plate 1 and a mounting part 412 rotatably installed on the base 411 via bearings. The base 411 can be fixed to the bottom support plate 1 by several screws. The lower end of the threaded rod 42 is connected to the mounting part 412 by a threaded engagement, and its upper end passes through the light hole 33 on the milling cutter shank support plate 3 and is threadedly connected to the upper limit member 5 and the lower limit member 6, respectively. The upper limit component 5 and the lower limit component 6 are respectively engaged on the upper and lower sides of the milling cutter shank support plate 3 to fix it. The top of the threaded rod 42 is fixedly equipped with a handwheel 43 for easy operation. By rotating the handwheel 43, the threaded rod 42 can be rotated, thereby driving the upper limit component 5 and the lower limit component 6 to move, so that the milling cutter shank support plate 3 can be raised and lowered along the guide rod 2 to the designated position.

[0023] The upper limit member 5 and the lower limit member 6 have multiple annularly distributed limiting grooves 61 machined around the threaded holes on their contact surfaces facing the milling cutter shank support plate 3. Correspondingly, limiting protrusions 34 matching the limiting grooves 61 are integrally formed around the through holes 33 on the upper and lower surfaces of the milling cutter shank support plate 3. These limiting protrusions 34 adopt a wedge-shaped design, and the limiting grooves 61 are configured as wedge-shaped grooves that cooperate with them. Preferably, the inclined ends of the limiting protrusions 34 are rounded. Example 2

[0024] See Figure 6As shown, in another improved embodiment, the difference from Embodiment 1 is that a soft buffer pad 7 is added to the upper surface of the bottom support plate 1. The soft buffer pad 7 can be connected to the upper surface of the bottom support plate 1 by adhesive. In this case, the placement hole 11 should be made in this soft buffer pad 7. The soft buffer pad 7 can be supported by elastic materials such as silicone, rubber or sponge, which can effectively protect the end of the milling cutter. Example 3

[0025] See Figures 7-8 As shown, in another improved embodiment, the difference from Embodiment 1 is that an elastic buffer ring 321 is added to the milling cutter hole 32. This elastic buffer ring 321 has an "I"-shaped cross-section and a through-center. Its upper and lower ends are respectively snapped and fixed to the upper and lower edges of the milling cutter hole 32, facilitating the removal and replacement of the elastic buffer ring 321. The elastic buffer ring 321 can be made of elastic materials such as silicone or rubber, providing good cushioning protection for the inserted milling cutter shank and preventing damage to the milling cutter due to collisions during storage.
