Description

Technical Field

[0001] This utility model relates to the field of machine tool tool changing technology, and in particular to a beam-suspended straight-row tool magazine. Background Technology

[0002] The tool magazine device installed on the machine tool mainly provides a tool storage position and can move the spindle directly above the selected tool according to the program control to exchange tools. Its working principle is to use the relative cooperation between the spindle and the tool magazine to achieve the purpose of the spindle taking the tool from the tool magazine for cutting.

[0003] Existing wall-mounted straight-row tool magazines include sensor-type tool magazines and sweeping tool magazines. These two types of tool magazines have complex structures, high maintenance costs, long tool changing times, and frequent alarm and emergency stop situations. Moreover, if the sensors are damaged and not replaced in time, collisions may occur during tool changing, causing deformation of the entire tool magazine structure and rendering the tool magazine unusable.

[0004] To address this, a suspended linear tool magazine is disclosed in the prior art (Announcement No.: CN203125225U, Announcement Date: 2013.08.14). It reduces reliance on precision parts by using a suspension method, becomes more stable, the fixed position can be changed, the tool change stroke is shortened, the tool change time is reduced by 1 / 3, and the original thin linear guide is changed to a thick linear guide, resulting in higher tool change accuracy.

[0005] However, the above solution does not include a protective device to shield the tools on the tool magazine. Since the number of tool changes during machine tool processing is relatively small, metal chips will accumulate on the tool magazine and unused tools during milling, which may scratch the unused tools. Moreover, the metal chips will also block the normal tool changing, seriously affecting the service life of the tool magazine and tools. Utility Model Content

[0039] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] like Figure 1-9As shown, a beam-suspended straight-row tool magazine of this utility model includes a tool magazine base plate 1, a pushing mechanism 2, and a suspension plate 3;

[0041] The pushing mechanism 2 is fixedly installed on the bottom side of the suspension plate 3, and the tool magazine bottom plate 1 is located below the suspension plate 3. The pushing mechanism 2 drives the tool magazine bottom plate 1 to move back and forth.

[0042] A crossbar 4 is detachably installed on the front side of the tool magazine base plate 1 by screws. Side plates 5 are fixedly installed on both the left and right ends of the crossbar 4. A horizontal groove 6 is formed on the side plate 5. A right-angle groove 7 that is bent downward is formed at the front end of the horizontal groove 6. A snap-fit ​​groove 8 is formed between the right-angle groove 7 and the horizontal groove 6.

[0043] A shielding cover 9 is fixedly installed on the front side of the suspension plate 3. The crossbar 4 and the knife holder 13 are both installed in the shielding cover 9 with clearance fit. A cover plate 10 is hinged to the upper edge of the front side of the shielding cover 9. Pulley frames 11 are fixedly installed on both the left and right ends of the rear side of the cover plate 10. A sliding wheel 12 is rotatably installed on the pulley frame 11. The sliding wheel 12 is slidably installed between the horizontal groove 6, the right angle groove 7 and the snap-fit ​​groove 8.

[0044] The principle is as follows: When the pushing mechanism 2 moves the tool magazine base plate 1 forward, the side plates 5 on both sides of the crossbar 4 will push the cover plate 10 on the front side of the shield 9 to flip open through the sliding wheels 12. When the cover plate 10 is open, the sliding wheels 12 on the pulley frame 11 will slide to the horizontal groove 6. At this time, continuing to drive the crossbar 4 forward can effectively push out the tool, which is convenient for tool changing. When the pushing mechanism 2 moves the tool magazine base plate 1 backward, the crossbar 4 will retract into the shield 9. At the same time, the horizontal groove 6 will turn through the right angle groove 7 and lock the sliding wheel 12 on the rear side of the cover plate 10 into the locking groove 8. At this time, the cover plate 10 can be driven to close, thus working with the shield 9 to protect the crossbar 4. The tool installed on the crossbar 4 is not affected by metal chips during machine tool processing, thus ensuring the stability during tool changing and ensuring the service life of the tool and the tool magazine.

[0045] Furthermore, several tool holders 13 are detachably mounted on the crossbar 4 via screws, and the tool holders 13 are arranged in an array at equal distances from each other. Different types of tools can be installed on each tool holder 13. When changing tools, the cover plate 10 can be opened and the tool can be extended out of the shielding cover 9. When machining on the machine tool, the tool can be retracted into the shielding cover 9 and the cover plate 10 can be closed to shield metal chips and ensure the service life of each tool holder 13 and tool.

[0046] Furthermore, the front side of the cover plate 10 is engraved with tool numbers 14, and each tool number 14 is set in a one-to-one correspondence with the front of the tool holder 13; this enables quick tool changing and avoids placing the wrong type of tool on the wrong tool holder 13.

[0047] Furthermore, the left and right ends of the rear side of the shield 9 are both formed with slots 15, and the side plates 5 are installed in the slots 15 with corresponding gaps; this ensures that the side plates 5 can move back and forth stably without movement jamming or other movement interference, making the tool magazine more stable.

[0048] Furthermore, the rear side of the shielding cover 9 is formed with a through groove 16, and the tool magazine base plate 1 is fitted into the through groove 16 with a clearance fit; this allows the tool magazine base plate 1 to move back and forth relative to the shielding cover 9, thereby achieving the effect of extending or retracting the tool holder 13.

[0049] Furthermore, at least two guide rails 17 are fixedly installed on the bottom side of the suspension plate 3. The at least two guide rails 17 are arranged parallel to each other, and at least two sliders 18 are slidably installed on each guide rail 17. The sliders 18 are fixedly installed on the tool magazine base plate 1, making the forward and backward movement of the suspension plate 3 more stable.

[0050] Furthermore, the pushing mechanism 2 includes a motor 2.1, a lead screw support 2.2, a rotating lead screw 2.3, and a positioning block 2.4. The motor 2.1 and the lead screw support 2.2 are both fixedly installed on the bottom side of the suspension plate 3. The rotating lead screw 2.3 is rotatably installed in the lead screw support 2.2. The motor 2.1 drives the rotating lead screw 2.3 to rotate. The positioning block 2.4 is fixedly installed on the tool magazine base plate 1. The positioning block 2.4 has a threaded hole 19 formed on it. The rotating lead screw 2.3 is helically installed in the threaded hole 19. This allows the pushing mechanism 2 to drive the tool magazine base plate 1 to move back and forth stably.

[0051] Furthermore, the tool magazine base plate 1 is formed with a clearance groove 20, and the bottom end of the motor 2.1 is fitted into the clearance groove 20 with a clearance fit; this makes the installation of the motor 2.1 more reasonable, can effectively utilize the space, and thus reduce the volume of the entire tool magazine.

[0052] Furthermore, a rear protective cover 21 is fixedly installed at the rear end of the bottom side of the suspension plate 3, and the tool magazine base plate 1 is set in the rear protective cover 21; this can effectively cover the rear end of the tool magazine base plate 1, thereby preventing metal chips from affecting the forward and backward movement of the tool magazine base plate 1 during machine tool processing.

[0053] Furthermore, right-angle connecting brackets 22 are fixedly installed between the left and right sides of the front end of the rear protective cover 21 and the shielding cover 9, making the installation of the rear protective cover 21 more stable.

[0054] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
