Description

Technical Field

[0001] This utility model belongs to the field of measurement technology, specifically, it relates to a structure of an articulated arm measurement system. Background Technology

[0002] An articulated arm measuring machine is a portable coordinate measuring instrument based on a multi-joint rotational structure. It is primarily based on the movement principles of the human arm, and unlike traditional Cartesian coordinate measuring machines that use length as the reference, it uses angle as the core measurement basis.

[0003] The structure of an articulated arm measuring machine consists of multiple fixed-length arms connected by joints that can rotate around mutually perpendicular axes (these joints are often compared to the shoulder, elbow, and wrist joints in the human body). Measuring components such as scanners are mounted on the end of the arm.

[0004] Articulated arm measuring machines have the following advantages: flexibility and multi-axis freedom: the multi-joint structure gives the equipment a rich degree of freedom of movement, which can easily reach various measurement parts of complex workpieces and break through the measurement dead zones of traditional equipment; Rapid measurement, no preheating required: Eliminates the cumbersome preheating process of traditional precision measuring equipment, allowing for rapid start-up and measurement work, significantly improving measurement efficiency.

[0005] Strong adaptability to complex environments: Compared with the stringent environmental requirements of traditional fixed coordinate measuring machines, it can better adapt to complex industrial environments such as workshops and on-site operations, reducing the interference of environmental factors on measurements.

[0006] Thanks to its excellent flexibility and portability, articulated arm measuring machines have applications in almost all industrial fields that require precision measurement, playing an important role in scenarios such as machinery manufacturing, automotive parts inspection, and aerospace component verification.

[0007] While articulated arm measuring machines have significant advantages, they also have certain limitations. When using articulated arm measuring machines, they mainly rely on manual operation, and the measurement efficiency is closely related to the operator's proficiency. Measurement cannot be automated, resulting in low measurement efficiency. The articulated arm measuring machine is equipped with a trigger button, which requires a person to continuously apply force to the trigger button during measurement, making the measurement operation inconvenient.

[0027] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0028] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0029] In some embodiments of this application, an articulated arm measurement system is proposed, referring to... Figures 1-8 As shown, it has: a first measurement mode and a second measurement mode. Specifically, the first measurement mode is an automatic measurement mode and the second measurement mode is a manual measurement mode.

[0030] The articulated arm measurement system in this embodiment can achieve automatic measurement.

[0031] The articulated arm measurement system includes: Articulated arm measuring machine 100, including: body 110; and The articulated arm assembly 120 is mounted on the body 110 and includes multiple articulated arms connected sequentially by joints and a measuring component 130 connected to the end articulated arm.

[0032] The body 110 is fixedly arranged and is used to support the articulated arm assembly 120 and the measuring component 130.

[0033] In some embodiments of this application, the plurality of articulated arms include an A-joint arm, a B-joint arm, a C-joint arm, a D-joint arm, an E-joint arm, an F-joint arm, and a G-joint arm that are sequentially connected to the body 110.

[0034] Among them, the C-joint arm and the D-joint arm are relatively long and are located in the middle position, and they are connected by rotation.

[0035] The measuring component 130 is a scanner, which can be used to scan the workpiece to achieve measurement. The method of measuring the workpiece by scanning is an existing method, which will not be described in detail here.

[0036] A trigger button 140 is located on the measuring component 130. When the trigger button 140 on the measuring component 130 is triggered, the articulated arm measuring machine 100 can start working.

[0037] The first measuring table 210 has a first placement position 211 for placing the workpiece on its upper part, and the first placement position 211 corresponds to the position of the measuring component 130. Robot 300 is mounted on first measuring platform 210, which includes output terminal 310.

[0038] Robot 300 can be a six-axis robot 300.

[0039] The connecting member 400 is detachably connected between the measuring component 130 and the output terminal 310, and a trigger switch 500 for triggering the trigger button 140 is provided above it.

[0040] The connection between the measuring component 130 and the output end 310 is achieved through the connecting component 400, thereby realizing the connection between the robot 300 and the measuring component 130.

[0041] The connecting member 400 is detachably connected between the measuring component 130 and the output end 310. During use, the articulated arm measuring system can be switched between the first measuring mode and the second measuring mode by removing or installing the connecting member 420.

[0042] The trigger switch 500 can be used to trigger the trigger button 140, thereby enabling automatic triggering of the trigger button 140 on the articulated arm measuring machine 100.

[0043] When the articulated arm measurement system is in the first measurement mode, the connecting member 400 connects the measuring component 130 and the output terminal 310, the trigger switch 500 triggers the trigger button 140, and the robot 300 drives the measuring component 130 to measure the workpiece at the first placement position 211.

[0044] In specific settings, the measurement path of the articulated arm measuring machine 100 can be pre-stored inside the robot 300. After the robot 300 is connected to the articulated arm measuring machine 100, the articulated arm measuring machine 100 can be driven to move and measure according to the measurement path.

[0045] When the articulated arm measuring system is in the second measuring mode, the connecting member 400 is not connected to the measuring component 130 and the output end 310, and the articulated arm measuring machine 100 is operated to measure at least the workpiece at the first placement position 211.

[0046] In this embodiment, the articulated arm measurement system includes a connecting member 400. The connecting member 400 connects the output end 310 of the robot 300 to the measuring component 130 of the articulated arm measuring machine 100, achieving a rigid connection between the robot 300 and the measuring component 130. The connecting member 400 also includes a trigger switch 500 for triggering a trigger button 140. When the articulated arm measuring machine 100 needs to measure a workpiece, the trigger switch 500 on the connecting member 400 triggers the trigger button 140, and the robot 300's movement drives the connecting member 400 and the articulated arm measuring machine 100 connected to the connecting member 400 to automatically measure the workpiece at the first placement position 211 of the first measuring table 210. This achieves automatic measurement by the articulated arm measuring machine 100, greatly improving measurement efficiency. Secondly, the trigger switch 500 set on the connecting member 400 can maintain the triggering effect on the trigger button 140, which is more convenient than the existing measurement method that requires the person to hold it all the time. In addition, the connecting member 400 in this embodiment is detachably connected to the output end 310 and the measuring component 130. During use, the user can disconnect the connection between the output end 310 and the measuring component 130 according to the actual measurement scenario requirements, that is, separate the connecting member 400 from the measuring component 130. At this time, the articulated arm measuring machine 100 can be used for the second measurement mode, that is, the manual measurement mode, so that the entire articulated arm measuring machine 100 can not only realize automatic measurement, but also realize manual measurement, which can easily adapt to different user needs.

[0047] In some embodiments of this application, the articulated arm measurement system further includes: The second measuring platform 220 is provided with the articulated arm measuring machine 100 and the second placement position 221 for placing the workpiece.

[0048] The body 110 of the articulated arm measuring machine 100 can be fixedly mounted on the second measuring table 220.

[0049] When the articulated arm measuring system is in the second measuring mode, the articulated arm measuring machine 100 can also measure the workpiece at the second placement position 221.

[0050] When the articulated arm measurement system is in manual measurement mode, the articulated arm measuring machine 100 can measure not only the workpiece at the first placement position 211, but also the workpiece at the second placement position 221, realizing multi-station measurement of the articulated arm measurement system.

[0051] In some embodiments of this application, the connecting member 400 includes: a member body 410, with a connecting portion 420 formed at one end of the member body 410 for connecting to the output terminal 310.

[0052] The connecting part 420 is a connecting flange formed at one end of the component body 410, which fits against the output end 310 and is locked and fixed to the output end 310 by screws.

[0053] An insertion portion 430 is formed within the component body 410, and an insertion protrusion 131 that mates with the insertion portion 430 is provided on the measuring component 130.

[0054] The insertion part 430 is an insertion slot formed in the component body 410, and it is arranged at the other end of the component body 410.

[0055] The insertion protrusion 131 on the measuring component 130 is inserted into the insertion slot to achieve insertion positioning with the component body 410.

[0056] A locking assembly for locking the measuring component 130 inserted into the component body 410 and the component body 410.

[0057] In some embodiments of this application, a set of locking threaded holes 411 is provided on the connecting member 400. Multiple sets of locking threaded holes 411 are provided and arranged along the axial direction of the member body 410. Each set of locking screw holes includes multiple locking threaded holes 411 arranged circumferentially along the member body 410. The locking assembly is provided in multiple sets, which respectively cooperate with multiple sets of locking screw hole groups. Each locking assembly includes multiple locking screws that cooperate with locking thread holes 411. The multiple locking screws are screwed into the inner ends of the multiple locking screw holes and abut against the outer wall of the insert protrusion 131.

[0058] By screwing multiple locking screws into the connecting member 400 and abutting against the insert protrusion 131, the axial and circumferential directions of both are limited.

[0059] In some embodiments of this application, a protruding guide portion is formed on the insert protrusion 131, which extends along the axial direction of the insert protrusion 131, and a protruding guide groove 431 that mates with the protruding guide portion is formed on the inner wall of the insert portion 430.

[0060] The raised guide portion is a guide protrusion formed on the outer side wall of the insertion protrusion 131. The protrusion guide groove 431 and the protrusion guide portion are adapted to each other. During assembly, the protrusion guide portion of the insertion protrusion 131 can be inserted along the protrusion guide groove 431. The cooperation between the protrusion guide portion and the protrusion guide groove 431 can guide the connection between the measuring component 130 and the connecting component 400, so that the two can be quickly assembled into place.

[0061] Furthermore, the cooperation between the raised guide groove 431 and the raised guide part also enables the rotation limit of the connecting member 400 and the measuring member 130, ensuring the firmness of the connection between the two.

[0062] In some embodiments of this application, the connecting member 400 includes a first connecting segment 440 and a second connecting segment 450, wherein the axis of the first connecting segment 440 is parallel to or coincides with the axis of the output terminal 310, and the second connecting segment 450 is disposed perpendicular to the first connecting segment 440.

[0063] Since the output end 310 is arranged vertically, the first connecting section 440 is set to be parallel to or coincide with its axis to ensure that it can be matched and connected with the output end 310. Since the measuring component 130 is set approximately horizontally, the second connecting section 450 is arranged perpendicular to the first connecting section 440, i.e., horizontally, to facilitate matching and connection with the measuring component 130.

[0064] The measuring component 130 has an interface portion, and the insertion protrusion 131 is formed at the interface portion. The end face of the interface portion is an inclined surface 132, and the end face of the second connecting section 450 is adapted to the inclined surface 451 at the end face of the interface portion.

[0065] The end face of the second connecting section 450 is also a bevel 451. When the insertion protrusion 131 is inserted into the connecting member 400, the bevel 451 of the second connecting section 450 and the inclined surface 132 at the interface fit together, resulting in a good aesthetic appearance after connection.

[0066] In some embodiments of this application, the trigger switch 500 is an electromagnetic switch having an extended state that can trigger the trigger button 140 and a retracted state that does not trigger the trigger button 140.

[0067] The articulated arm measurement system includes a controller that controls the on / off state of the electromagnetic switch, enabling the trigger switch 500 to be triggered or de-triggered.

[0068] When the electromagnetic switch is energized, it extends and presses against the trigger button 140 to maintain its activation. When the power is off, the circuit retracts, releasing the trigger button 140 from being triggered.

[0069] In some embodiments of this application, a switch mounting bracket 600 is included, which is locked and fixed to the component body 410. It has a first connecting arm 610 connected to the component body 410 and its position relative to the component body 410 is adjustable in the horizontal direction. The second connecting arm 620 is connected to the trigger switch 500, and its position relative to the trigger switch 500 in the vertical direction is adjustable.

[0070] A first locking hole is provided on the component body 410, and a first connecting elongated hole 611 is provided on the first connecting arm 610. The first locking screw passes through the first connecting elongated hole 611 and is screwed and fixed in the first locking hole to press and fix the first connecting arm 610. The first locking screw does not protrude from the first locking hole to avoid interfering with the installation of the insertion protrusion 131.

[0071] When adjusting the position, loosen the first locking screw, then move the first connecting arm 610 horizontally until it is in place, and then tighten the first locking screw.

[0072] A second locking hole is provided on the trigger switch 500, and a second connecting elongated hole 621 is provided on the second connecting arm 620. The second locking screw passes through the second connecting elongated hole 621 and is screwed and fixed in the second locking hole to press and fix the second connecting arm 620.

[0073] When adjusting the position, loosen the second locking screw, and then move the trigger switch 500 up and down relative to the second locking screw through the second connecting elongated hole 621 to adjust and change the vertical position.

[0074] In some embodiments of this application, the articulated arm measuring machine 100 includes a D-articulated arm 121; The articulated arm measurement system includes a suspension mechanism, which includes: The base 710 is attached to the second measuring stage 220; The support frame 720 is connected to the base 710 and has a cantilever portion 722; The elastic connector 730 has one end connected to the end of the cantilever 722 and the other end having an elastic connection portion 731 that connects to the D-joint arm 121.

[0075] The base 710 includes a base 710 body and a magnetic component 711 disposed at the bottom of the base 710 body. The base 710 is attracted and fixed on the second measuring stage 220 by the magnetic component 711 at the bottom.

[0076] The support frame 720 serves to support and bear loads. It includes a main frame 721 and a cantilever 722 connected to the main frame 721. The cantilever 722 is a cantilever rod. A reinforcing rod is connected between the main frame 721 and the cantilever 722 to enhance the support strength of the entire support frame 720.

[0077] The elastic connector 730 can be either a spring or an elastic rope.

[0078] The elastic connection part 731 is a threaded interface part with an external thread on its upper part and an internal threaded hole at the end of the D joint arm 121. The elastic connection part 731 is fixed to the end of the D joint arm 121 by screwing on the external thread.

[0079] The base 710, the support frame 720, and the elastic connector 730 constitute the suspension support frame of the articulated arm measuring machine 100. It is connected to the articulated arm through the elastic connector 730 to form a flexible connection, ensuring that the articulated arm can move freely to perform measurements.

[0080] When the articulated arm moves in space under the automated drive of the robot 300, the elastic connector 730 can effectively limit the unexpected swing amplitude of the arm and reduce the positional drift caused by multi-joint linkage, thereby minimizing the positional uncertainty of the articulated arm in automated operation, providing stable support for the automated measurement process, and significantly improving the safety factor of the system operation.

[0081] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
