Description

Technical Field

[0001] This utility model relates to the field of friction stir welding, specifically an automatic tool magazine tilt angle adjustment device. Background Technology

[0002] During the welding process of friction stir welding equipment, it is necessary to change the welding tools to ensure the continuous welding work. Different tool holders are required for different welding conditions. To facilitate the use of tool holders by the welding spindle, the conventional strategy is to fix different types of tool holders in the tool magazine, and provide different tool holders for the friction stir welding equipment through the tool magazine.

[0003] Currently, conventional tool magazines, as described in application number "202410832016.2", rotate to move the tool holder to a set position for tool changing by the welding equipment. However, in friction stir welding, an angle is required between the stirring head axis and the workpiece plane to achieve tilted stirring welding. The tilt angle dynamically adjusts depending on the welding conditions. After adjustment, the welding equipment cannot smoothly align with the tool magazine for tool changing. To avoid this, each tool change requires adjusting the welding equipment's tilt angle to match the tool magazine's angle before changing the tool, and then adjusting the welding equipment's angle back to the set angle afterward. This tool changing method is extremely inefficient. Furthermore, during tool changing, horizontal position errors easily occur between the tool magazine and the spindle in the radial alignment direction. If the spindle and the tool holder of the tool magazine are not precisely aligned in the radial alignment direction, the tool cannot be gripped or released. Therefore, how to adjust the horizontal position of the tool magazine and the spindle along the radial docking direction while adjusting the tool magazine tilt angle is a technical problem that urgently needs to be solved. Utility Model Content

[0004] To avoid and overcome the technical problems existing in the prior art, this utility model provides an automatic tool magazine tilt angle adjustment device. This utility model can realize the adjustment of the tool magazine tilt angle and the position of the tool magazine along the radial docking direction.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic tool magazine tilt adjustment device includes a power source fixed on a mounting bracket, which drives a rotating shaft to rotate; the tool magazine is mounted on the rotating shaft and rotates synchronously with the rotating shaft, and the tool magazine and the rotating shaft are slidably engaged along the axial direction of the rotating shaft; an adjustment base plate is driven by an adjustment seat on the mounting bracket, thereby slidingly engaging with the mounting bracket along a direction parallel to the rotating shaft; a stabilizing component is provided on the adjustment base plate for clamping and positioning the tool magazine, the clamping force applied by the stabilizing component to the tool magazine is less than the rotational force applied by the power source to the rotating shaft, and the tool magazine slides synchronously with the adjustment base plate along the axial direction of the rotating shaft.

[0007] As a further embodiment of this utility model: the adjusting seat includes a first adjusting screw and a second adjusting screw arranged along the direction parallel to the rotation axis. The first adjusting screw is threadedly engaged with the adjusting seat. After the end of the first adjusting screw abuts against the adjusting base plate, it pushes the adjusting base plate to slide away from the adjusting seat. The second adjusting screw is engaged with the adjusting seat in a free-rotation manner. The end of the second adjusting screw is threadedly engaged with the adjusting base plate to drive the adjusting base plate to slide towards the adjusting seat. Either the first adjusting screw or the second adjusting screw can be used.

[0008] As a further improvement of this utility model: the tool magazine is fixed on the mounting base plate, and the mounting base plate is provided with at least two sets of adapter blocks that slide with the rotating shaft. The adapter blocks and the rotating shaft transmit power through key transmission.

[0009] As a further improvement of this utility model, the stabilizing component consists of at least two sets of positioning blocks fixed on the adjusting base plate. The positioning blocks slide along the axial direction with the rotating shaft. The two adjacent sets of positioning blocks clamp at least one set of transition blocks to drive the tool magazine to move synchronously with the adjusting base plate.

[0010] As a further improvement of this utility model: a guide groove is provided on the adjusting base plate along the direction of parallel rotation axis, and the length of the guide groove corresponds to the sliding adjustment distance of the adjusting base plate; after the fastening screw passes through the guide groove, the adjusting base plate is fixed to the mounting bracket.

[0011] As a further embodiment of this utility model: the power source includes a drive motor, which is fixed on the mounting bracket by a motor mounting seat, and the drive motor transmits power to the rotating shaft through a reducer.

[0012] As a further improvement of this utility model, a power-off brake that works in conjunction with the rotating shaft is installed on the reducer.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model fixes the tool magazine on a rotating shaft and drives the rotating shaft to rotate through a power source, which can drive the tool magazine to quickly adjust the tilt angle. When it is necessary to adjust the position of the tool magazine and the spindle in the docking direction, the adjusting base plate is driven to slide along the rotating shaft through the adjusting seat, which can clamp and push the tool magazine to slide synchronously along the rotating shaft, thereby realizing the position adjustment in the radial docking direction, ensuring accurate docking of the tool and the spindle, and reducing tool changing errors.

[0017] 2. The first and second adjusting screws of this utility model adopt a bidirectional adjustment mechanism, which can push or pull back the adjusting base plate to achieve fine adjustment of the tool magazine position and adapt to changes in different spindle positions.

[0018] 3. With the cooperative design of the positioning block and the adapter block, this utility model ensures the stability of the tool magazine by clamping, and avoids relative sliding between the adjustment base plate and the tool magazine due to vibration or uneven force.

[0019] 4. The guide groove of this utility model allows the adjustment base plate to slide within a set range. After adjustment, the adjustment base plate can be tightened to the mounting bracket by tightening screws to ensure the stability of the adjustment base plate.

[0020] 5. This utility model achieves precise control of the tool magazine rotation by combining a drive motor with a reducer. The rotation angle of the rotating shaft is determined by a grating disk. After the tilt angle is adjusted, the rotating shaft is clamped and fixed by a power-off brake to achieve locking after the tilt angle adjustment.

[0021] 6. This utility model can realize automatic control of tilt angle. When applied to friction stir welding, it can greatly improve production efficiency and realize welding with tilt angle and machining without angle. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-2 In this embodiment of the invention, an automatic tool magazine tilt angle adjustment device includes a mounting bracket 1. A motor mounting base 4 is fixed to the side of the mounting bracket 1. A drive motor 41, used as a power source, is mounted on the motor mounting base 4. The drive motor 41 drives a rotating shaft 42 to rotate via a reducer 43. A power-off brake 44 is also independently mounted on the reducer 43. When the tool magazine 6 is adjusted to a preset angle, the system controls the power-off brake 44 to de-energize and engage the rotating shaft 42, completing the angle adjustment process.

[0033] A grating disk 421 is provided at the end of the rotating shaft 42, and the rotation angle of the rotating shaft 42 is monitored through the grating disk 421.

[0034] The mounting bracket 1 is equipped with an adjusting base plate 2 that fits snugly against the mounting bracket 1. A sliding guide rail 11 protrudes from the mounting bracket 1 and is arranged parallel to the rotation axis 42. The adjusting base plate 2 slides with the sliding guide rail 11 for sliding guidance and positioning. A guide groove 24 is formed on the adjusting base plate 2 along the direction parallel to the rotation axis 42. The length of the guide groove 24 corresponds to the sliding adjustment range of the adjusting base plate 2 along the sliding guide rail 11. A fastening screw 25 passes through the guide groove 24 to fix the adjusting base plate 2 to the mounting bracket 1. When adjusting the position of the adjusting base plate 2, first loosen the fastening screw 25 to avoid applying preload to the adjusting base plate 2. After the position adjustment of the adjusting base plate 2 is completed, tighten the fastening screw 25 again to reapply preload to the adjusting base plate 2. The arrangement direction of the sliding guide rail 11 is parallel to the radial connection direction of the tool magazine 6 and the spindle.

[0035] At least two sets of positioning blocks 21 are fixed on the adjusting base plate 2. In this embodiment, two sets of positioning blocks 21 are provided, and both sets of positioning blocks 21 slide in engagement with the shaft of the rotating shaft 42. The two sets of positioning blocks 21 are fixed to the adjusting base plate 2 by bolts. There is a gap between the two sets of positioning blocks 21 to clamp and fix the adapter block 51. During installation, only a slight clamping state is maintained, so that the adapter block 51 is slightly stressed and pushed to slide by the tight fit. In actual use, four sets of positioning blocks 21 can also be provided, with each pair of positioning blocks 21 clamping and fixing one adapter block 51. The number of positioning blocks 21 is usually set to match the number of adapter blocks 51, or twice the number of adapter blocks 51, so as to fix the adapter block 51 in a two-clamp-one manner.

[0036] The tool magazine 6 is fixed on the mounting base plate 5. Two sets of adapter blocks 51 are fixed on the mounting base plate 5, which slide and engage with the rotating shaft 42. There are at least two sets of adapter blocks 51; in this embodiment, two sets are used to provide dual positioning support for the mounting base plate 5. Power is transmitted between the adapter blocks 51 and the rotating shaft 42 via a key drive.

[0037] When the tool magazine 6 is adjusted at an angle, the rotating shaft 42 drives the adapter block 51 to rotate synchronously, which in turn drives the mounting base plate 5 and the tool magazine 6 on the mounting base plate 5 to rotate synchronously to achieve angle adjustment. When it is necessary to make fine adjustments to the tool magazine 6 in the horizontal direction, the adjusting base plate 2 slides along the sliding guide rail 11. While sliding, the adapter block 51 is clamped and fixed by two sets of positioning blocks 21, thereby driving the mounting base plate 5 and the tool magazine 6 to slide synchronously along the sliding guide rail 11, thereby achieving fine adjustments to the left and right positions.

[0038] To adjust the position of the base plate 2, an adjusting seat 3 is fixed on the mounting bracket 1. The adjusting seat 3 contains two sets of first adjusting screws 22 and second adjusting screws 23 arranged parallel to the rotating shaft 42. The first adjusting screw 22 is threaded into the adjusting seat 3. During the tightening process, the end of the first adjusting screw 22 abuts against the body of the base plate 2, thereby pushing the base plate 2 to move away from the adjusting seat 3.

[0039] The adjusting seat 3 has a countersunk hole, and the head of the second adjusting screw 23 abuts against the countersunk hole, thus forming a free-spinning engagement. The end of the second adjusting screw 23 forms a threaded engagement with the adjusting base plate 2. When the second adjusting screw 23 is turned clockwise in the countersunk hole of the adjusting seat 3, the second adjusting screw 23 spins freely in the countersunk hole and drives the adjusting base plate 2 to move towards the adjusting seat 3 through the thread. When the second adjusting screw 23 is turned counterclockwise, the second adjusting screw 23 is disengaged from the adjusting base plate 2 and the countersunk hole. When adjusting the first adjusting screw 22, the second adjusting screw 23 is disengaged from the adjusting base plate 2. When adjusting the second adjusting screw 23, the first adjusting screw 22 is loosened to prevent it from abutting against the adjusting base plate 2.
