Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of high-precision XY adjustment modules, and particularly relates to a high-precision XY adjustment module. Background Technology
[0002] In the field of modern industrial manufacturing, water-guided laser equipment has been widely used in precision machining, micromachining and other fields due to its advantages of high precision and non-contact processing. During operation, water-guided laser equipment requires precise adjustment of the processing position to ensure processing accuracy and quality. Therefore, a high-precision XY adjustment module is one of the key components of water-guided laser equipment.
[0003] Existing XY adjustment modules have certain shortcomings in their constraint methods for the adjustment seat. Traditional adjustment modules often struggle to achieve rigid, gapless constraint on the adjustment seat, resulting in low constraint accuracy. This leads to significant amplitude deviations during the up-and-down movement of the adjustment seat, which not only affects the processing accuracy of the water-guided laser equipment but also reduces its stability during operation, failing to meet the demands of high-precision processing. Therefore, we propose a high-precision XY adjustment module. Utility Model Content
[0004] The purpose of this invention is to provide a high-precision XY adjustment module to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides a high-precision XY adjustment module, comprising:
[0006] The outer shell has a top cover fixedly installed on one side. On the side of the outer shell opposite to the top cover, there are a plurality of second mounting slots and a plurality of first mounting slots. A fixing block is fixedly installed in each of the first mounting slots and the second mounting slots. An adjustment seat is provided inside the outer shell and between the first mounting slots and the second mounting slots. A first universal ball is provided in the fixing block. A nozzle is fixedly installed on one side of the adjustment seat.
[0007] Two threaded sleeves are fixedly installed inside the housing. An adjusting screw is installed inside the threaded sleeve. One end of the adjusting screw is provided with a second universal ball. Two grooves are opened inside the housing. A spring that is fixed to the adjusting seat is fixedly installed in the groove.
[0008] In this technical solution, several first universal balls inside the outer shell and top cover can constrain the adjusting seat in the vertical direction, allowing the adjusting seat to move in the XY direction. When it is necessary to adjust the position of the adjusting seat in the XY direction, the adjusting screw can be rotated. Under the action of the thread, the adjusting screw will rotate in the threaded sleeve and move towards the adjusting seat until the second universal ball at one end of the adjusting screw contacts the adjusting seat and squeezes the adjusting seat to move. At this time, the corresponding spring will contract and generate a rebound force due to compression. During the movement of the adjusting seat, the first universal ball in contact with the adjusting seat will rotate. Several first universal balls can constrain the adjusting seat. The upper and lower surfaces of the adjusting seat are rigid and gapless, which greatly improves the constraint accuracy, so that the vertical movement amplitude of the adjusting seat can be less than 0.002mm. The movement of the adjusting seat in the XY direction ultimately drives the nozzle to move, thereby achieving the purpose of laser coupling and improving the stability of the water-guided laser equipment during use.
[0009] In the above technical solution, furthermore, a plurality of the first mounting slots are distributed in a ring with equal spacing.
[0010] In this technical solution, the first mounting slots are distributed in a ring with equal spacing, which makes the constraint effect on the adjustment seat more stable.
[0011] In the above technical solution, furthermore, a plurality of the second mounting slots are distributed in a ring with equal spacing.
[0012] In this technical solution, the several second mounting slots are distributed in a ring with equal spacing, which makes the constraint effect on the adjusting seat more stable.
[0013] In the above technical solution, the first universal ball is in contact with the adjustment seat.
[0014] In this technical solution, it is ensured that several first universal balls can constrain the position of the adjustment seat, and the upper and lower surfaces of the adjustment seat are rigid and gapless constraints, which greatly improves the constraint accuracy.
[0015] In the above technical solution, the adjusting screw is further connected to the threaded sleeve.
[0016] In this technical solution, the adjusting screw will be displaced when it rotates due to the action of the thread.
[0017] In the above technical solution, furthermore, the two ends of the spring are tightly welded to the inner wall of the groove and the outer wall of the adjusting seat, respectively.
[0018] In this technical solution, the structure of the spring is kept stable. When the adjusting screw is rotated, it will rotate inside the threaded sleeve and move towards the adjusting seat under the action of the thread. This continues until the second universal ball at one end of the adjusting screw contacts the adjusting seat and squeezes the adjusting seat to move. At this time, the corresponding spring will be compressed and will contract and generate a rebound force, ensuring that the spring can operate normally.
[0019] In the above technical solution, the outer shell is further fixed to the upper cover by bolts.
[0020] In this technical solution, the outer casing can be fixed to the top cover with bolts, thus facilitating disassembly and installation.
[0021] In the above technical solution, the first universal ball is movably connected to the fixed block, and the second universal ball is movably connected to one end of the adjusting screw.
[0022] In this technical solution, it is ensured that the first universal ball can move within the fixed block, and the second universal ball can move within one end of the adjusting screw.
[0023] The beneficial effects of this utility model are:
[0024] This high-precision XY adjustment module uses a universal ball to constrain the adjustment seat, making the upper and lower surfaces of the adjustment seat rigid and gapless, which greatly improves the constraint accuracy. The vertical movement of the adjustment seat can be less than 0.002mm, improving the stability of the water-guided laser equipment during use. Attached Figure Description

[0039] Example 1: This example provides a high-precision XY adjustment module, including:
[0040] The outer shell 1 has a top cover 2 fixedly installed on one side. On the side of the outer shell 1 opposite to the top cover 2, there are several second mounting slots 12 and several first mounting slots 11 respectively. Fixing blocks 9 are fixedly installed in both the first mounting slots 11 and the second mounting slots 12. An adjusting seat 5 is provided inside the outer shell 1 and between the first mounting slots 11 and the second mounting slots 12. A first universal ball 10 is provided in the fixing block 9. A nozzle 4 is fixedly installed on one side of the adjusting seat 5.
[0041] Two threaded sleeves 7 are fixedly installed inside the outer casing 1. An adjusting screw 3 is installed inside the threaded sleeve 7. One end of the adjusting screw 3 is provided with a second universal ball 13. Two grooves 6 are opened inside the outer casing 1. A spring 8 fixed to the adjusting seat 5 is fixedly installed in the groove 6.
[0042] The first universal balls 10 inside the outer shell 1 and the upper cover 2 can constrain the adjusting seat 5 in the vertical direction, which allows the adjusting seat 5 to move in the XY direction. When it is necessary to adjust the position of the adjusting seat 5 in the XY direction, the adjusting screw 3 can be rotated. Under the action of the thread, the adjusting screw 3 will rotate in the threaded sleeve 7 and move towards the adjusting seat 5 until the second universal ball 13 at one end of the adjusting screw 3 contacts the adjusting seat 5 and squeezes the adjusting seat 5 to move. At this time, the corresponding spring 8 will be compressed and generate a rebound force. During the displacement of the adjusting seat 5, the first universal ball 10 in contact with the adjusting seat 5 will rotate. The first universal balls 10 can constrain the adjusting seat 5. The upper and lower surfaces of the adjusting seat 5 are rigid and gapless, which greatly improves the constraint accuracy, so that the vertical movement amplitude of the adjusting seat 5 can be less than 0.002mm. The movement of the adjusting seat 5 in the XY direction eventually drives the nozzle 4 to move, thereby achieving the purpose of laser coupling and improving the stability of the water-guided laser equipment during use.
[0043] Example 2: This example provides a high-precision XY adjustment module, which, in addition to the technical solutions of the above examples, also has the following technical features: a plurality of first mounting slots 11 are distributed in a ring at equal intervals.
[0044] Among them, the fact that several first mounting slots 11 are distributed in a ring with equal spacing makes the constraint effect on the adjustment seat 5 more stable.
[0045] Example 3: This example provides a high-precision XY adjustment module, which, in addition to the technical solutions of the above examples, also has the following technical features: a plurality of second mounting slots 12 are distributed in a ring at equal intervals.
[0046] Among them, the fact that several second mounting slots 12 are distributed in a ring with equal spacing makes the constraint effect on the adjustment seat 5 more stable.
[0047] Example 4: This example provides a high-precision XY adjustment module, which, in addition to the technical solutions of the above examples, also has the following technical features: the first universal ball 10 is in contact with the adjustment seat 5.
[0048] In this way, it is ensured that several first universal balls 10 can constrain the position of the adjusting seat 5, and the upper and lower surfaces of the adjusting seat 5 are rigid and gapless constraints, which greatly improves the constraint accuracy.
[0049] Example 5: This example provides a high-precision XY adjustment module. In addition to the technical solutions of the above examples, it also has the following technical features: the adjusting screw 3 is threadedly connected to the threaded sleeve 7.
[0050] The adjusting screw 3 will be displaced when it rotates due to the action of the thread.
[0051] Example 6: This example provides a high-precision XY adjustment module. In addition to the technical solutions of the above examples, it also has the following technical features: the two ends of the spring 8 are tightly welded to the inner wall of the groove 6 and the outer wall of the adjustment seat 5, respectively.
[0052] To ensure the structural stability of spring 8, the adjusting screw 3 is rotated. Under the action of the thread, the adjusting screw 3 will rotate inside the threaded sleeve 7 and move towards the adjusting seat 5 until the second universal ball 13 at one end of the adjusting screw 3 contacts the adjusting seat 5 and squeezes the adjusting seat 5 to move. At this time, the corresponding spring 8 will be compressed and will contract and generate a rebound force, ensuring that spring 8 can operate normally.
[0053] Example 7: This example provides a high-precision XY adjustment module. In addition to the technical solutions of the above examples, it also has the following technical features: the outer shell 1 is fixed to the upper cover 2 by bolts.
[0054] Specifically, it is ensured that the outer casing 1 can be fixed to the upper cover 2 by bolts, thereby facilitating disassembly and installation.
[0055] Example 8: This example provides a high-precision XY adjustment module. In addition to the technical solutions of the above examples, it also has the following technical features: the first universal ball 10 is movably connected to the fixed block 9, and the second universal ball 13 is movably connected to one end of the adjusting screw 3.
[0056] Specifically, this ensures that the first universal ball 10 can move within the fixed block 9, thereby ensuring that the adjusting seat 5 can move more rapidly, smoothly, and stably, and that the second universal ball 13 can move within one end of the adjusting screw 3.
[0057] Working principle: Several first universal balls 10 inside the outer shell 1 and the upper cover 2 can constrain the adjusting seat 5 in the vertical direction, which allows the adjusting seat 5 to move in the XY direction. When it is necessary to adjust the position of the adjusting seat 5 in the XY direction, the adjusting screw 3 can be rotated. Under the action of the thread, the adjusting screw 3 will rotate in the threaded sleeve 7 and move towards the adjusting seat 5 until the second universal ball 13 at one end of the adjusting screw 3 contacts the adjusting seat 5 and squeezes the adjusting seat 5 to move. At this time, the corresponding spring 8 will be compressed and generate a rebound force. During the displacement of the adjusting seat 5, the first universal ball 10 in contact with the adjusting seat 5 will rotate. Several first universal balls 10 can constrain the adjusting seat 5. The upper and lower surfaces of the adjusting seat 5 are rigid and gapless, which greatly improves the constraint accuracy, so that the vertical movement range of the adjusting seat 5 can be less than 0.002mm. The movement of the adjusting seat 5 in the XY direction eventually drives the nozzle 4 to move, achieving the purpose of laser coupling and improving the stability of the water-guided laser equipment during use.
