Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of parts of a five-axis machining center, in particular to a tool magazine structure of a five-axis machining center. Background Art
[0002] The tool magazines used in existing five-axis machining centers are all externally mounted, and the tools are completely exposed to the outside. The dust and debris generated during machining can easily enter the tool magazine and fall on the tool handle, which can easily cause the spindle to fail to pick up the tool during tool change, affecting the quality and efficiency of tool change, and even damaging the spindle. In addition, the tools are more easily contaminated by cutting fluid and iron chips, which affects the accuracy of tool clamping during tool change and is prone to tool jamming. If the tool magazine fails and the tool in the tool magazine needs to be replaced, the processing needs to be stopped, which will cause maintenance to take up a lot of time and affect production efficiency. Utility Model Content
[0003] The utility model provides a hidden tool magazine structure which can prevent a tool from being contaminated by iron filings.
[0004] The tool magazine structure of the five-axis machining center described in the utility model includes a fixed seat installed at the opening of the five-axis machining center, a guide rail moving relative to the fixed seat, and a driving mechanism on the fixed seat for driving the guide rail to push and push out the movement. A tool magazine for placing cutting tools is installed on the guide rail, and a cover plate for covering the opening of the five-axis machining center is provided at the end of the guide rail.
[0005] Preferably, the fixing seat has fixing plates extending upward on both sides, and sliding grooves are provided on the inner sides of the two fixing plates facing each other, and the guide rails are embedded and installed in the sliding grooves.
[0006] Preferably, a limit block is further provided at one end of the guide rail located inside the five-axis machining center, and baffles for blocking the limit block are provided on both sides of the upper part of the fixed seat.
[0007] Preferably, the limit block is also provided with a buffer opposite to the side wall of the fixing seat.
[0008] Preferably, the driving mechanism comprises a cylinder and a push rod connected to the cylinder, and an end of the push rod is connected to the guide rail.
[0009] Preferably, an upwardly protruding boss is further provided on the guide rail between the fixed seat and the tool magazine, the height of the boss is flush with the height of the cover plate, and one end of the boss close to the tool magazine is inclined downward toward the tool magazine to form a slope.
[0010] The tool magazine structure of the five-axis machining center, when changing tools, when the driving mechanism drives the guide rail to extend the tool magazine, rapid tool change is achieved. After the tool change is completed, the driving mechanism retracts the guide rail and closes the cover plate on the opening of the five-axis machining center to prevent the iron filings generated during the machining process of the five-axis machining center from affecting the tool.

[0012] Figure 2 A schematic diagram of the tool magazine structure of a five-axis machining center Figure 2 .
[0013] Figure 3 This is a schematic diagram of the tool magazine installation structure of a five-axis machining center. DETAILED DESCRIPTION
[0014] like Figure 1-3 As shown, a tool magazine structure of a five-axis machining center includes a fixed seat 1 installed at the opening of the five-axis machining center, a guide rail 2 that moves relative to the fixed seat, and a driving mechanism 3 that drives the guide rail to push and push out the fixed seat. A tool magazine 4 for placing tools is installed on the guide rail, and a cover plate 5 for covering the opening of the five-axis machining center is provided at the end of the guide rail. When changing tools, when the driving mechanism drives the guide rail to extend the tool magazine, a quick tool change is achieved. After the tool change is completed, the driving mechanism retracts the guide rail and closes the cover plate on the opening of the five-axis machining center to prevent the iron filings generated by the five-axis machining center during the machining process from affecting the tools.
[0015] The fixing seat has fixing plates extending upward on both sides, and sliding grooves are provided on the inner sides opposite to each other of the two fixing plates. The guide rail is embedded and installed in the sliding grooves. The fixing seat has fixing plates extending upward on both sides, and sliding grooves are provided on the inner sides opposite to each other of the two fixing plates, so that the guide rail is hidden in the fixing seat and moves relative to the fixing seat.
[0016] A stop block 7 is also provided at one end of the guide rail located inside the five-axis machining center, and baffles 6 for blocking the stop block are provided on both sides of the upper part of the fixed seat. The stop block cooperates with the baffle to limit the distance of the guide rail being pushed out, and prevents the guide rail from falling off the fixed seat due to being pushed out too far. Furthermore, when the guide rail is pushed out, an impact will be generated at the moment when the stop block contacts the baffle. In order to avoid damage to the tool caused by the impact, a buffer 8 is also provided on the stop block opposite to the side wall of the fixed seat to reduce the impact of the stop block on the baffle.
[0017] The driving mechanism comprises a cylinder 9 and a push rod 10 connected to the cylinder, and the end of the push rod is connected to the guide rail.
[0018] The guide rail between the fixed seat and the tool magazine is also provided with an upwardly protruding boss, the height of which is flush with the height of the cover plate, and the end of the boss close to the tool magazine is inclined downward toward the tool magazine to form a slope. By setting the boss on the guide rail between the fixed seat and the tool magazine, the baffle 7 can be installed on the boss to increase the installation area, thereby increasing the stability and strength of the baffle; secondly, after the guide rail extends outward relative to the five-axis machining center, a part of the space above the tool magazine needs to be reserved to clamp the tool, which also results in that after the guide rail extends outward relative to the five-axis machining center, the cover plate used to cover the opening of the five-axis machining center cannot continue to cover the five-axis machining center. The center opening will allow residual dust and debris from the outside to enter the five-axis machining center; thirdly, the upward protruding boss can be against the edge of the opening of the five-axis machining center, which can limit the four directions of up, down, left and right, increase the stability of the guide rail when it is extended, and avoid the guide rail from shaking up, down, left and right; in addition, the upward protruding boss and its height is flush with the cover plate, which can just seal the opening of the five-axis machining center. At the same time, in order to prevent the part of the boss extending out of the five-axis machining center from interfering with the clamping parts of the tool changing, the end of the boss close to the tool magazine is tilted downward toward the tool magazine to form a slope, leaving space for clamping the tool.
