Description

Technical Field

[0001] This invention relates to the field of laser tracker technology, and more specifically to a machine tool assembly system with laser tracker detection. Background Technology

[0002] The laser tracking measurement system is a high-precision, portable, large-size coordinate measurement system based on a single laser tracker. It emits and receives lasers reflected back from the target mirror, and combines precision ranging and angle measurement technology to determine the three-dimensional spatial coordinates of the target point in the spherical coordinate system in real time. It is widely used in high-end equipment manufacturing fields such as aerospace, automobile manufacturing, heavy machinery, shipbuilding and rail transportation, for key links such as assembly and inspection of large components, tooling positioning and machine tool precision calibration.

[0003] Patent document 202110599171.0 discloses a mobile measuring trolley device for a laser tracker, comprising an upper sleeve, a lifting and adjusting assembly disposed within the cavity of the upper sleeve, a lower sleeve connected to the upper sleeve via a fastening assembly, a support assembly connected to the lower sleeve via a bracket, and a rocker assembly for driving the lifting and adjusting assembly; the lifting and adjusting assembly includes a lifting rod, the top of which is provided with a mounting base connected to the laser tracker; the support assembly includes a bottom bracket and fixed legs and wheels disposed on the bottom bracket. The mobile measuring trolley device for a laser tracker of this invention allows the laser tracker to be moved smoothly and safely to other measuring stations without shutting down, enabling the next measuring operation, and allows for flexible lifting and adjusting of the laser tracker.

[0004] It is evident that, in order to ensure the integrity and comprehensiveness of data measurement, the laser tracker usually needs to be moved to multiple stations. To address this, the laser tracker is combined with a mobile trolley. However, to ensure the measurement range, the height adjustment of the laser tracker is essential. When the laser tracker is raised, the mobile trolley carries it. Existing lifting structures have a high center of gravity and are prone to tipping over. Therefore, there is an urgent need for a machine tool assembly system with laser tracker detection to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a machine tool assembly system with laser tracker detection to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A machine tool assembly system with laser tracker detection includes a transfer carriage, an instrument head, and a targeting assembly. The instrument head is vertically mounted on the transfer carriage and works in conjunction with the targeting assembly for tracking detection. The system also includes: a mounting slot located at the upper end of the transfer carriage; a reference sleeve located within the mounting slot, containing a retractable first sleeve, a second sleeve, and a third sleeve arranged sequentially therein, with the instrument head fixedly mounted on the upper end of the third sleeve; and a pneumatic assembly for driving the first, second, and third sleeves to extend sequentially and retract in reverse order.

[0008] Preferably, the upper end of the reference sleeve and each sleeve is provided with an inner ring body, and the lower end of each sleeve is provided with an outer ring body. The inner ring body is used to limit the rise of the outer ring body.

[0009] Preferably, the pneumatic assembly includes an air inlet and an air outlet disposed within a reference sleeve. Limiting components are disposed on the first sleeve, the second sleeve, and the third sleeve. When any sleeve rises to its highest position, the limiting component on it cancels the limitation on the next sleeve in the sequence.

[0010] Preferably, the limiting component includes a sliding hole at the lower end of each sleeve, a limiting member is elastically and movably disposed in the sliding hole, and one end of the limiting member near the center of the reference sleeve can be movably inserted into another adjacent sliding hole. A magnetic block is provided on the upper end of the inner wall of the reference sleeve and each sleeve. When the height of the limiting member corresponds to that of the magnetic block, the limiting member is magnetically attracted to move away from another adjacent sliding hole.

[0011] Preferably, an elastic groove is provided on the lower side of the sliding hole, and a force-receiving part is provided on the limiting member that is movably embedded in the elastic groove. A first elastic member is provided between the inner wall of the elastic groove and the force-receiving part.

[0012] Preferably, each sleeve is provided with an inflatable sealing assembly on its lower outer wall. When any sleeve rises to its highest position, the limiting member on it moves to make the inflatable sealing assembly communicate with the interior of the reference sleeve.

[0013] Preferably, the inflatable sealing assembly includes an inflatable ring disposed on the lower outer wall of each sleeve, and the inflatable ring is connected to the inside of the sliding hole through an airflow channel.

[0014] Preferably, the reference sleeve is movably disposed in the mounting groove, the inner bottom surface of the mounting groove is provided with a sealing ring, and the transfer vehicle is provided with an elastic pressing component for pressing the reference sleeve onto the sealing ring.

[0015] Preferably, the elastic pressing component includes a reference ring fixedly mounted on the transfer vehicle, a plurality of support plates evenly arranged on the lower circumference of the reference ring and fixedly connected to the side wall of the reference sleeve, and a second elastic element connecting the reference ring and the support plates.

[0016] Preferably, the inner wall of the reference ring is provided with a buffer ring for positioning the reference sleeve.

[0017] In the above technical solution, the beneficial effects of the present invention are:

[0018] This machine tool assembly system with laser tracker detection uses pneumatic components to allow the first, second, and third sleeves to extend sequentially by inflation and retract in reverse order by deflation. This not only enables height adjustment of the instrument head but also ensures smooth lifting and lowering. Furthermore, the overall weight of the first, second, and third sleeves is small after inflation and extension, preventing excessive raising of the system's center of gravity and ensuring the stability of the transfer vehicle's movement.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0031] Please see Figure 1-6 This invention provides a machine tool assembly system with laser tracker detection, comprising a transfer carriage 1, an instrument head 2, and a targeting assembly. The instrument head 2 is vertically mounted on the transfer carriage 1 and works in conjunction with the targeting assembly for tracking detection. The system also includes: a mounting groove 3 located at the upper end of the transfer carriage 1; a reference sleeve 4 located within the mounting groove 3, containing a retractable first sleeve 5, a second sleeve 6, and a third sleeve 7 arranged sequentially, with the instrument head 2 fixedly mounted at the upper end of the third sleeve 7; and a pneumatic assembly for driving the first sleeve 5, the second sleeve 6, and the third sleeve 7 to extend sequentially and retract in reverse order.

[0032] Specifically, the transfer vehicle 1 is an automated guided vehicle, which can set the movement path according to the detection needs. This is existing technology and will not be described in detail. The instrument head 2 is the main body of the laser tracker, which has horizontal and vertical rotation functions. The targeting component includes a magnetic target base and a target ball. The magnetic target base can be adsorbed and fixed on the machine tool, and the target ball can be adsorbed and installed on the magnetic target base. Thus, the target ball can move with the machine tool in various degrees of freedom to cooperate with the instrument head 2 for tracking and detection. The mounting groove 3 is located at the upper center of the transfer vehicle 1 and is a cylindrical groove. The reference sleeve 4 is preferably cylindrical and is coaxially arranged with the mounting groove 3. The first sleeve 5, the second sleeve 6, and the third sleeve 7 are also preferably cylindrical, with the first sleeve 5 at the outermost layer and the third sleeve 7 at the innermost layer. The reference sleeve 4 and the first sleeve 5, the first sleeve 5 and the second sleeve 6, and the second sleeve 6 and the third sleeve 7 are all sealed and movablely connected, thereby making the interiors of the reference sleeve 4, the first sleeve 5, the second sleeve 6, and the third sleeve 7 all sealed spaces. The pneumatic assembly is used to control the inflation and deflation of the sealed space to drive the lifting and lowering of each sleeve. In practical use, the pneumatic components in this technical solution inflate the internal space of the reference sleeve 4, causing the first sleeve 5, the second sleeve 6, and the third sleeve 7 to extend sequentially. Conversely, by deflating the internal space of the reference sleeve 4, the first sleeve 5, the second sleeve 6, and the third sleeve 7 retract sequentially. This not only achieves height adjustment of the instrument head 2 but also ensures smooth lifting and lowering. Furthermore, after the first sleeve 5, the second sleeve 6, and the third sleeve 7 are inflated and extended, their overall structural weight is small, thus preventing the overall center of gravity of the system from rising excessively and ensuring the smooth movement of the transfer vehicle 1.

[0033] Compared with the prior art, the machine tool assembly system with laser tracker detection proposed in this embodiment of the invention, by setting up pneumatic components, can extend the first sleeve 5, the second sleeve 6 and the third sleeve 7 in sequence by inflating, and retract the first sleeve 5, the second sleeve 6 and the third sleeve 7 in reverse sequence by deflating. This not only realizes the height adjustment of the instrument head 2, but also makes the lifting and lowering process smooth. In addition, after the first sleeve 5, the second sleeve 6 and the third sleeve 7 are inflated and extended, their overall structural weight is small, so as not to raise the overall center of gravity of the system too much, thus ensuring the smooth movement of the transfer cart 1.

[0034] As a preferred embodiment, the upper end of the reference sleeve 4 and each sleeve is provided with an inner ring body, and the lower end of each sleeve is provided with an outer ring body. The inner ring body is used to limit the upward movement of the outer ring body. Specifically, the inner ring body is in contact with the outer wall of the sleeve adjacent to it on its inner side for relative movement, and the outer ring body is in contact with the inner wall of the sleeve adjacent to it on its outer side for relative movement. A convex ring is provided on the outer side of the upper end of each sleeve. The convex ring is used to limit the downward movement of the sleeve, so that after any sleeve is contracted to its shortest length, it can press down on another sleeve one level lower through the convex ring. In addition, keyway connections are provided between the reference sleeve 4 and the first sleeve 5, between the first sleeve 5 and the second sleeve 6, and between the second sleeve 6 and the third sleeve 7, thereby limiting the lifting and lowering movement of the first sleeve 5, the second sleeve 6, and the third sleeve 7.

[0035] As a preferred embodiment, the pneumatic assembly includes an air inlet 8 and an air outlet 9 disposed within a reference sleeve 4. Limiting components are provided on the first sleeve 5, the second sleeve 6, and the third sleeve 7. When any sleeve rises to its highest position, the limiting component on it cancels the restriction on the next sleeve in the sequence. Specifically, the transfer vehicle 1 integrates an air pump, and the air inlet 8 and the air outlet 9 are both connected to and controlled by the air pump. The limiting component on the first sleeve 5 is used to limit the second sleeve 6 to its shortest contraction position, and the limiting component on the second sleeve 6 is used to limit the third sleeve 7 to its shortest contraction position. When the first sleeve 5 rises to its highest position, the limiting component on it cancels the restriction on the second sleeve 6, and when the second sleeve 6 rises to its highest position, the limiting component on it cancels the restriction on the third sleeve 7, thereby achieving the sequential extension of the first sleeve 5, the second sleeve 6, and the third sleeve 7.

[0036] As a further preferred technical solution of this embodiment, the limiting component includes a sliding hole 10 provided at the lower end of each sleeve. A limiting member 11 is elastically and movably disposed within the sliding hole 10. The end of the limiting member 11 near the center of the reference sleeve 4 can be movably inserted into another adjacent sliding hole 10. Magnetic blocks 12 are provided at the upper end of the inner wall of both the reference sleeve 4 and each sleeve. When the limiting member 11 and the magnetic block 12 are at the same height, the limiting member 11 is magnetically attracted and moves away from the other adjacent sliding hole 10. Specifically, the sliding hole 10 is disposed on the outer ring portion at the lower end of the sleeve, penetrating the outer ring, and its penetration direction is perpendicular to the axial direction of the sleeve. The end of the limiting member 11 near the center of the reference sleeve 4 is its inner end, and the end away from the center of the reference sleeve 4 is its outer end. When each sleeve is retracted to its shortest position, the sliding holes 10 at its lower end are horizontally aligned, and the outer ends of each limiting member 11 are inside the sliding holes 10 with a certain distance remaining. Thus, the inner end of the limiting member 11 on the first sleeve 5 inserts into the sliding hole 10 on the second sleeve 6, and the inner end of the limiting member 11 on the second sleeve 6 inserts into the sliding hole 10 on the third sleeve 7. The limiting member 11 is made of a magnetically attractive material. The magnetic block 12 is positioned near the lower part of the inner ring. When any sleeve rises to its highest position, its lower limiting member 11 corresponds exactly to the outer magnetic block 12, causing the outer end of the limiting member 11 to move under the attraction of the magnetic block 12, thereby disengaging the limiting effect. The attractive force of the magnetic blocks 12 on the reference sleeve 4, the first sleeve 5, and the second sleeve 6 is progressively reduced.In practical use, when the reference sleeve 4 is inflated, the first sleeve 5 rises first. When the first sleeve 5 reaches its highest position, the limiting member 11 on it corresponds to the magnetic block 12 on the inner side of the reference sleeve 4. Therefore, the limiting member 11 is attracted and moved by the magnetic block 12. The outer end of the limiting member 11 is easily attracted and fixed by the magnetic block 12, while the inner end of the limiting member 11 moves away from the sliding hole 10 on the second sleeve 6. As inflation continues, the second sleeve 6 continues to rise. Similarly, after the second sleeve 6 reaches its highest position, the limiting member on the third sleeve 7 is removed and it continues to rise. Subsequently, before the air is released from the reference sleeve 4, the limiting member 11 on the first sleeve 5 is attracted and fixed to the magnetic block 12 on the reference sleeve 4, and the limiting member 11 on the second sleeve 6 is attracted and fixed to the magnetic block 12 on the first sleeve 5. The third sleeve 7... The limiting member 11 is attracted and fixed to the magnetic block 12 on the second sleeve 6. Since the attraction of the magnetic block 12 on the reference sleeve 4, the first sleeve 5 and the second sleeve 6 decreases in sequence, and the third sleeve 7 directly supports the instrument head 2, during the degassing process of the reference sleeve 4, the third sleeve 7 is first subjected to force and descends, causing the limiting member 11 on it to separate from the magnetic block 12 on the second sleeve 6. After the third sleeve 7 descends to the lowest position, the second sleeve 6 is subjected to force and descends again, causing the limiting member 11 on it to separate from the magnetic block 12 on the first sleeve 5. Similarly, after the second sleeve 6 descends to the lowest position, the first sleeve 5 is subjected to force and descends again, causing the limiting member 11 on it to separate from the magnetic block 12 on the reference sleeve 4. This achieves the reverse order of contraction of the first sleeve 5, the second sleeve 6 and the second sleeve 6, and the smooth descent of the instrument head 2.

[0037] As a further preferred technical solution of this embodiment, an elastic groove 13 is provided on the lower side of the sliding hole 10, and a force-receiving part 14 is provided on the limiting member 11 that is movably embedded in the elastic groove 13. A first elastic member 15 is provided between the inner wall of the elastic groove 13 and the force-receiving part 14. Specifically, the force-receiving part 14 is provided on the lower side of the limiting member 11, and the first elastic member 15 is provided on the side of the force-receiving part 14 away from the center of the reference sleeve 4. The first elastic member 15 prevents the force-receiving part 14 from moving to the side away from the center of the reference sleeve 4. The first elastic member 15 is preferably a spring. Under the elastic force of the first elastic member 15, the limiting member 11 is in the initial position. This initial position corresponds to the outer end of the limiting member 11 being inside the sliding hole 10 with a certain distance left, and the inner end of the limiting member 11 being inserted into another adjacent sliding hole 10.

[0038] In another embodiment of the present invention, an inflatable sealing assembly is provided on the lower outer wall of each sleeve. When any sleeve rises to its highest position, the limiting member 11 on it moves to make the inflatable sealing assembly communicate with the interior of the reference sleeve 4. Specifically, the inflatable sealing assembly is provided on the upper side near the outer ring body to enhance the sealing between the outer wall of each sleeve and the inner ring body. When any sleeve rises to its highest position, the sleeve needs to maintain its height to ensure a seal. The inflatable sealing assembly can trigger the limiting member 11 and the magnetic block 12 to attract each other when the sleeve rises to its highest position, thereby making the inflatable sealing assembly communicate with the interior of the reference sleeve 4. Thus, some of the gas in the reference sleeve 4 during the inflation process can enter the inflatable sealing assembly to strengthen the seal between the reference sleeve 4 and the sleeves, as well as between each sleeve.

[0039] As a preferred technical solution of this embodiment, the inflatable sealing assembly includes an inflatable ring 16 disposed on the lower outer wall of each sleeve. The inflatable ring 16 is connected to the inside of the sliding hole 10 through an airflow channel. Specifically, the inflatable ring 16 is disposed near the upper side of the outer ring body. The airflow channel is arc-shaped and bends downward to connect to the upper inner wall of the sliding hole 10 near the center of the reference sleeve 4. The upper side of the end of the limiting member 11 near the center of the reference sleeve 4 is provided with a notch, which makes it easier for the limiting member 11 to avoid the connection between the airflow channel and the sliding hole 10 when the limiting member 11 is attracted to the magnetic block 12. In actual use, when any sleeve rises to its highest position, its inflation ring 16 corresponds to the outer inner ring body, and its limiting member 11 is attracted and moved by the corresponding magnetic block 12. Thus, the limiting member 11 avoids the connection between the airflow channel and the sliding hole 10, so that the airflow channel is connected to the inside of the reference sleeve 4. Then, during the inflation process inside the reference sleeve 4, a part of the gas can be introduced into the inflation ring 16 through the sliding hole 10 and the airflow channel. The inflation ring 16 expands to enhance the seal between the sleeve and the inner ring body.

[0040] After the instrument head 2 is raised, the transfer vehicle 1 carries it and moves, which poses a risk of collision with objects at a height and makes the transfer vehicle 1 more likely to tip over. In this regard, the following embodiments are proposed to reduce this risk.

[0041] In another embodiment of the present invention, the reference sleeve 4 is movably disposed in the mounting groove 3. A sealing ring 17 is provided on the inner bottom surface of the mounting groove 3. The transfer cart 1 is provided with an elastic pressing component for pressing the reference sleeve 4 onto the sealing ring 17. Specifically, the sealing ring 17 is coaxially disposed in the mounting groove 3. The elastic pressing component presses the reference sleeve 4 onto the sealing ring 17, thereby ensuring that the internal space of the reference sleeve 4 is sealed. When the instrument head 2 rises, and during the movement of the transfer cart 1, if the instrument head 2 accidentally collides with a high object, the instrument head 2 causes the reference sleeve 4 to swing through each sleeve, so that the reference sleeve 4 resists the elastic downward pressure of the elastic pressing component and forms an opening gap with the sealing ring 17. Thus, the gas inside the reference sleeve 4 escapes quickly through this opening gap, and the instrument head 2 immediately descends, thereby quickly lowering the overall center of gravity of the transfer cart 1 and the instrument head 2, thereby reducing the risk of the transfer cart 1 tipping over.

[0042] As a preferred technical solution in this embodiment, the elastic pressing component includes a reference ring 18 fixedly mounted on the transfer carriage 1. Multiple support plates 19, fixedly connected to the side wall of the reference sleeve 4, are evenly arranged on the lower circumference of the reference ring 18. A second elastic element 20 connects the reference ring 18 and the support plates 19. Specifically, the reference ring 18 is coaxial with the mounting groove 3. The reference ring 18 is connected to the upper end of the transfer carriage 1 by circumferentially spaced support blocks, ensuring that the internal space of the mounting groove 3 is not enclosed. Preferably, there are 3-6 support plates 19, evenly arranged on the outer side wall of the reference sleeve 4, with a gap between the height of the support plates 19 and the inner bottom surface of the mounting groove 3 for their movement. The second elastic element 20 is preferably a spring, with each second elastic element 20 having the same specifications, applying elastic downward pressure evenly in all directions to the reference sleeve 4, and the sum of the downward pressures is sufficient to maintain the overall vertical stillness of the reference sleeve 4, each sleeve, and the instrument head 2.

[0043] As a preferred technical solution in this embodiment, the inner wall of the reference ring 18 is provided with a buffer ring 21 for positioning the reference sleeve 4. Specifically, the inner diameter of the reference ring 18 is larger than the outer diameter of the reference sleeve 4. The buffer ring 21 is preferably a sponge ring or an air cushion ring, which helps the reference sleeve 4 to be centered relative to the reference ring 18, and also provides buffer for the swaying of the reference sleeve 4.

[0044] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
