Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to a tool horizontal placement support structure and a tool magazine. Background Technology

[0002] Existing tool holders rely on spring deformation and their own deformation to generate a clamping force that secures the tool. The heavier the tool, the greater the clamping force required; otherwise, the tool will fall. When picking up or placing the tool, the servo mechanism and robot must overcome this clamping force to remove it from the tool holder. In this case, the clamping force becomes a load on the servo mechanism and robot. If the driving force of the servo mechanism and robot cannot overcome the spring force and deformation that generate the clamping force, the tool cannot be removed from the tool holder. During this process, the servo mechanism and robot still bear the weight of the tool; the same applies to manual tool handling.

[0003] A Chinese patent with publication number CN218904494U discloses a linear tool magazine, including tools, a tool holder that engages with the outer wall of the tool, a tool magazine bracket fixed below the tool holder, and a rotating base fixedly connected to the bottom of the tool magazine bracket. The tool magazine bracket in this patent is made of elastic plastic, making it prone to wear and damage. Furthermore, plastic has poor resistance to deformation, thus limiting the weight of tools it can accommodate, and the tool holder cannot withstand significant off-center loads. The angled opening can enclose the tool holder, but this requires applying a certain amount of force to enlarge the opening when loading or unloading tools, making manual operation difficult. For automated tool loading and unloading, the load on the servo mechanism or multi-joint robot needs to be increased.

[0004] Chinese Patent CN220637079U discloses a rapid tool changing device, including a tool magazine and a tool changing mechanism. The tool magazine includes multiple first tool holders and a first driving mechanism for moving the first tool holders. The first tool holders cooperate with the tool shank to elastically clamp the tool. The tool changing mechanism includes a tool arm, a moving mechanism, and a second driving mechanism. The tool arm is provided with two opposing second tool holders. The moving mechanism drives the tool arm to move between a tool pick-up station and a tool changing station. The second driving mechanism drives the two second tool holders to switch between the tool pick-up station and the tool changing station. The second tool holders cooperate with the tool shank to fix and clamp the tool, and at the tool pick-up station, the second tool holders and the first tool holders can simultaneously clamp the tool. This patented tool holder uses a C-shaped structure that can wrap around the tool handle. A spring at the rear provides clamping force. However, this means that a large force needs to be applied to enlarge the opening when picking up or putting down the tool. This type of tool holder is almost impossible to operate manually frequently. When picking up or putting down tools automatically, the load on the servo mechanism or multi-joint robot needs to be increased, resulting in high costs.

[0005] Chinese patent CN215848129U discloses an open-type CNC tool holder, comprising a frame, a tool holder base, and a base. The frame consists of two main frames, multiple sub-frames, and a frame beam. All main frames, sub-frames, and the frame beam are formed by bending steel pipes. The bottom ends of the two main frames are fixed parallel to two longitudinal beams of the base, and the top ends of the two main frames are connected by the frame beam. Sub-frames are installed at opposite positions on both main frames, and the multiple sub-frames are arranged in parallel. A tool holder base is installed between two opposite sub-frames, and the tool holder base is used to hold the tool holder. This type of tool holder places the tool vertically or at an angle, resulting in low space utilization because operational space must be left for loading and unloading the tool.

[0006] Therefore, the inventors believe that there is a need to provide a tool horizontal placement support structure that eliminates the problem of upper-layer tools affecting the retrieval of lower-layer tools, eliminates the need for staggered distribution of each layer, greatly reduces the floor area and space occupied by the tool magazine, and improves space utilization; it can also stably support tools, is suitable for various types of tools, and is applicable to situations where the tool's center of gravity position, tool body shape, and tool length are arbitrary, etc. Moreover, no additional force other than the tool's own weight is required when picking up and putting down tools, adapting to various occasions and having low assembly requirements. Utility Model Content

[0007] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a tool horizontal placement support structure and a tool magazine.

[0008] According to the present invention, a tool horizontal placement support structure includes: a tool magazine support frame and a horizontal tool holder, wherein a plurality of the horizontal tool holders are arranged in a matrix on the tool magazine support frame;

[0009] The horizontal tool holder includes a support frame and an angular positioning block. A groove is formed at the bottom of the tool shank. The support frame is provided with an upward-opening U-shaped groove that matches the groove. The angular positioning block is located at the bottom of the U-shaped groove of the support frame. The support frame and the angular positioning block cooperate to support the tool shank.

[0010] The tool magazine support frame has an opening that matches the support frame. The support frame is installed below the opening, and the tool passes through the opening and is placed horizontally on the horizontal tool holder.

[0011] Preferably, the arc diameter of the U-shaped groove of the support frame is 3-5 mm smaller than the outer diameter of the shank of the tool, and 1-3 mm larger than the bottom diameter of the groove of the shank of the tool.

[0019] According to the present invention, a tool magazine contains multiple horizontally placed tool support structures as described above.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. This utility model uses a support frame and angular positioning blocks to support and restrict the angular direction of the cutting tools, thus achieving complete positioning of the tools. Multiple horizontal tool holders are installed in a matrix on the tool magazine support frame, with the tools placed horizontally. There is no situation where upper-layer tools affect the removal of lower-layer tools, and there is no need for staggered distribution of each layer, which greatly reduces the floor area and space occupied by the tool magazine, resulting in higher space utilization. The structure is simple, easy to manufacture, and has no vulnerable parts, which can maintain the tool magazine for a long service life without maintenance. It is suitable for various occasions and has low assembly requirements.

[0022] 2. This utility model uses a unique U-shaped groove structure in the support frame, which enables the support frame to stably support the tool.

[0033] Angular positioning block 4, cutting tool 5 Detailed Implementation

[0034] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0035] Example 1

[0036] like Figure 1-6As shown, a horizontal tool placement support structure provided by this utility model includes: a tool magazine support frame 1 and a horizontal tool holder 2. Multiple horizontal tool holders 2 are arranged in a matrix on the tool magazine support frame 1. The horizontal tool holder 2 includes a support frame 3 and an angular positioning block 4. A groove is formed at the bottom of the shank of the tool 5. The support frame 3 is provided with an upward-opening U-shaped groove that matches the groove. The angular positioning block 4 is located at the bottom of the U-shaped groove of the support frame 3. The support frame 3 and the angular positioning block 4 cooperate to support the shank of the tool 5 and completely position the tool 5. An elliptical opening that matches the support frame 3 is opened on the tool magazine support frame 1. The support frame 3 is installed below the elliptical opening and does not obstruct the elliptical opening. The tool 5 is placed horizontally on the horizontal tool holder 2 through the elliptical opening.

[0037] The cutting tool 5 can only enter and exit through the opening of the support frame 3. Under the influence of gravity, the horizontally placed cutting tool 5 will be stably positioned, and factors such as eccentricity of the cutting tool 5 cannot change its position. Therefore, the horizontal tool holder 2 has high tool positioning accuracy. The cutting tool 5 is restricted from moving along the tool axis in the U-shaped groove, and the elliptical through hole provides the space for the cutting tool 5 to move upward. When it is necessary to remove the cutting tool 5 from the tool magazine, the cutting tool 5 can only move along the tool axis and be removed from the tool magazine after being moved upward by the robot or operator to break free from the restriction of the U-shaped groove.

[0038] Both the support frame 3 and the angular positioning block 4 act on the shank of the tool 5. The arc diameter of the support frame 3 is smaller than the outer diameter of the shank of the tool 5, but larger than the bottom diameter of the groove of the tool 5, preventing the tool 5 from detaching from the support frame 3 in the axial direction. Preferably, the arc diameter of the U-shaped groove of the support frame 3 is 3-5 mm smaller than the outer diameter of the shank of the tool 5, and 1-3 mm larger than the bottom diameter of the groove of the shank of the tool 5. Taking the HSK63 tool as an example, the arc diameter of the support frame 3 ranges from 56 to 60 mm.

[0039] The groove sidewall of the tool 5 has an arc-shaped bevel, and the U-shaped groove of the support frame 3 has an arc-shaped bevel with the same angle and a very small gap. This allows the bevel of the support frame 3 to contact and position the bevel of the tool 5, preventing the tool 5 from rotating around the side of the support frame 3. Furthermore, this allows the support frame 3 to withstand the axial force of the tool 5, enabling automated tool handling by servo axes, robots, etc.

[0040] The angular positioning block 4 is used when angular positioning is required, preventing the tool 5 from rotating around its axis within the support frame 3. The upper two corners of the angular positioning block 4 are chamfered, providing a guiding function and allowing for greater tolerance during tool placement, thus reducing the positioning accuracy requirements for automated handling tools such as robots. The width of the angular positioning block 4 is 0.2-0.5 mm smaller than the width of the groove on the shank of the tool 5. The two sides of the angular positioning block 4 also serve a positioning function, and their width is 0.2-0.5 mm smaller than the groove width of the tool 5. Taking HSK63 as an example, the width of the angular positioning block 4 ranges from 15.5 to 15.8 mm.

[0041] The support frame 3 is equipped with a positioning groove, and the angular positioning block 4 has two corresponding positioning holes. The angular positioning block 4 is fastened to the support frame 3 with bolts. Both the support frame 3 and the angular positioning block 4 are thin metal plate structures made of steel; ordinary carbon steel is sufficient, but stainless steel can also be used. The small axial dimension allows the tool 5 to have any tool body shape and any tool length. The support frame 3 and the angular positioning block 4 have high strength, allowing the tool 5 to have any tool center of gravity position and weight. The contact parts of the support frame 3 and the angular positioning block 4 with the tool 5 can be surface treated to further improve wear resistance and strength. Due to its high rigidity, it can withstand very large off-center loads while maintaining positioning accuracy requirements, and can withstand all known tool weights and off-center loads, making it more versatile for various tools.

[0042] The support frame 3 is designed with a shape that matches the groove on the tool 5, enabling the support frame 3 to provide support at three points on the circumference of the groove on the tool 5, thus holding the tool 5 in place. The angular positioning block 4 is adapted to the size of the opening on the tool 5, which can prevent the tool 5 from rotating circumferentially on the support frame 3.

[0043] The support frame 3 adopts a U-shaped groove, with an arc-shaped positioning tool holder at the bottom and a vertical edge at the top. This solves the problem of the elastic clamping method used in ordinary tool clips / tool ​​sheaths. Due to deformation, elastic clamping cannot be applied to situations where the tool is heavy and the center of gravity of the tool is far away. It is also prone to wear. When picking up or putting down the tool 5, a certain amount of force is required to deform the elastic body. This achieves the goal of picking up or putting down the tool 5 without applying any additional force, relying solely on the weight of the tool 5. This greatly facilitates the convenience of manual operation.

[0044] When storing a large number of tools, the horizontal tool holders 2 need to be arranged in a matrix. The tool magazine support frame 1 is the frame used to install the horizontal tool holders 2 and is part of the tool magazine or tool cabinet. In practical applications, the tool magazine support frame 1 is cut to a suitable size according to the needs of the tool magazine or tool cabinet. The thickness of the horizontal tool holders 2 should not exceed 7mm, and the thickness of the tool magazine support frame 1 should be 5-10mm.

[0045] On the tool magazine support frame 1, the horizontal spacing between two adjacent support frames 3 is 0.5-1mm to prevent assembly failure due to machining errors. The spacing must also be designed according to the maximum diameter of the tools 5 that the tool magazine can accommodate, as specified in its technical requirements; different designs are required for different specifications. On the tool magazine support frame 1, the spacing between two support frames 3 in the gravity direction must be designed according to the elliptical opening on the tool magazine support frame 1, and the support frames 3 must not obstruct the elliptical opening. Furthermore, the spacing must also be designed according to the maximum diameter of the tools 5 that the tool magazine can accommodate, as specified in its technical requirements; different designs are required for different specifications.

[0046] In this application, the cutting tools 5 are placed horizontally, so there is no situation where the upper cutting tools 5 affect the removal of the lower cutting tools 5. There is no need for staggered distribution of each layer, which greatly reduces the floor area and space occupied by the tool magazine, and the space utilization rate is higher.

[0047] This application features a unique contour-following structure design for the support frame 3, with a U-shaped groove, which enables the support frame 3 to stably support the tool 5. It is suitable for various types of tools 5, including those with arbitrary center of gravity, arbitrary shape, and arbitrary length. Moreover, no additional force other than the weight of the tool 5 is required when picking up or putting down the tool 5.

[0048] This application, through reasonable tolerance control, enables the support frame 3 and the angle positioning block 4 to cooperate, not only to lift the tool 5, but also to accurately position the tool 5. The variation of the end face and the tail end of the tool 5 can meet the error requirement of 0.1mm, which can meet the tool picking and placing needs of various servo mechanisms, articulated robots, and manual operations.

[0049] The support frame 3 and the angular positioning block 4 are made of thin steel plate, which has good strength and wear resistance. This solves the problem that ordinary tool clips / tool ​​sleeves are made of elastic material and are prone to wear, requiring regular replacement of vulnerable parts. Under normal use, no maintenance is required.

[0050] The manufacturing and assembly processes of this application are simple. The simple manufacturing process has no vulnerable parts, which can maintain the tool magazine for a long service life without maintenance; the simple assembly process makes the horizontal tool holder 2 a standard product, adaptable to various occasions, and requires minimal assembly capability.

[0051] Example 2

[0052] Based on Embodiment 1, according to the present invention, a tool magazine is provided, in which multiple tools are placed horizontally on a support structure.

[0053] With increasing automation, cutting tools 5 on automated production lines are typically replaced and inspected in a dedicated tool changing room before entering the production line. This tool changing room requires a small footprint and a large capacity of manually operated tool magazines. This application utilizes the tool 5's own weight to fix it to the horizontal tool holder 2, eliminating the need for additional clamping forces and deformation. Therefore, for servo mechanisms, robots, and manual operation, there is no additional load besides the tool's own weight, significantly reducing costs.

[0054] This application solves the problems of large footprint and low space utilization in tool magazines or tool cabinets by adopting a horizontal tool placement method. It eliminates the issue of upper-layer tools affecting the retrieval of lower-layer tools and avoids the need for staggered layer distribution. Under the same space dimensions, it achieves the effect of centralized storage of a large number of tools. Through a unique contour-following structure design and angular positioning blocks 4 restricting angular movement, it solves the problem of not being able to design identical horizontal supports or use V-block supports due to differences in tool length, shape, weight, and center of gravity. This allows for the use of the same support frame for any tool length, shape, weight, and center of gravity position, eliminating the need for customized designs for different tools. The separate design of the support frame 3 and angular positioning blocks 4 solves the problem of complex processes, simplifying machining, manufacturing, and assembly, and achieving a high cost-performance ratio.
