Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of casting processing, in particular to a measuring device and an automatic cleaning line. BACKGROUND

[0002] Integrated die casting technology is an innovation in modern automobile manufacturing, aiming to simplify the complex structure of traditional white car body composed of multiple parts into a single part through highly integrated production methods. The core advantage of this technology is to significantly improve production efficiency, reduce manufacturing costs, and help achieve lightweight design of automobiles, thereby improving fuel economy and overall performance of vehicles.

[0003] Integrated die casting parts face a series of technical challenges during production, especially the problem of thermal forming dimensional fluctuation, which directly affects the dimensional consistency of the parts between different molds. This dimensional deviation not only brings difficulties to subsequent vehicle manufacturing, such as dimensional fluctuation in the welding process, but also further leads to quality problems such as uneven glue coating of the welding wheel cover, abnormal closing force of the rear door, and dimensional mismatch of key parts such as the front cover wing panel and headlight. In order to solve these problems, the industry currently mainly relies on gauge measurement, blue light measurement, and laser radar measurement for quality detection.

[0004] Although the above measurement technologies can achieve dimensional monitoring of integrated die casting parts to some extent, they all belong to offline measurement methods, which have the limitations of low measurement efficiency and inability to provide real-time feedback of dimensional information. CONTENT OF THE UTILITY MODEL

[0005] The present application provides a measuring device and an automatic cleaning line to solve the problem of measuring after precise positioning of the measured part.

[0006] In a first aspect, the present application provides a measuring device suitable for positioning and measuring a measured part, the measured part having at least three positioning points in a triangular distribution, the measuring device comprising a rack, a positioning assembly, a clamping assembly, and a detection assembly. The positioning assembly is arranged on the rack and comprises at least three positioning members in a triangular distribution, which are adapted to correspondingly abut the positioning points on the measured part. The clamping assembly is adapted to clamp or release the measured part. The detection assembly is adapted to detect the dimensional information of the measured part in the positioned state.

[0007] Beneficial effects: The measuring device can position the part under test using the positioning component. The positioning points on the part under test, in conjunction with the positioning component, allow the part to achieve a preset posture and precise positioning within the measuring device. The clamping component secures the positioned part, and the detection component measures the positioned part to obtain its dimensional information. The measuring device integrates online positioning and measurement of the part under test, improving measurement efficiency.

[0008] In one alternative embodiment, the positioning element includes a first support and a spring pin. The first support has a first end facing the frame and a second end facing the part to be tested, the first end of the first support being connected to the frame. The spring pin is disposed at the second end of the first support, and the telescopic end of the spring pin abuts against the positioning point on the part to be tested.

[0009] Beneficial effects: The telescopic end of the spring pin contacts the positioning point of the part under test, automatically compensating for minor dimensional deviations caused by thermal deformation or mold errors, ensuring a tight fit between the positioning point and the measuring device, and reducing human adjustment errors. The spring buffer design avoids scratches on the surface of the part under test due to rigid contact, making it particularly suitable for integrated die-cast parts made of easily damaged materials such as aluminum alloys. The elastic pressure stabilizes the part under test, reducing dimensional fluctuations caused by loosening during measurement and ensuring consistency in testing across multiple batches of parts.

[0010] In one optional embodiment, the part to be tested has a first surface and a second surface facing each other. The clamping assembly includes a driving member, a first clamping member, and a second clamping member. The first clamping member abuts against the second surface, and the second clamping member abuts against the first surface. The contact points between the first clamping member and the second surface and between the second clamping member and the first surface are located on opposite sides of the same position on the part to be tested. The output end of the driving member is connected to the first clamping member, and the driving member is adapted to drive the first clamping member to press against or disengage from the second surface of the part to be tested.

[0011] Beneficial effects: By abutting the first clamping element against the second surface and the second clamping element against the first surface, a symmetrical clamping force is formed, preventing deformation (such as warping) of the part under test due to unilateral pressure and ensuring that the part under test is in its natural state during measurement. The clamping points are located on both sides of the same position on the part under test, effectively fixing irregularly shaped structures (such as wheel covers and door frames) and avoiding localized stress concentration caused by traditional single-point clamping. The drive unit controls the clamping elements' clamping / unclamping, reducing manual intervention and ensuring compatibility with automated production line processes.

[0012] In one optional embodiment, the clamping assembly further includes a second support member having a first end facing the frame and a second end facing the part to be tested, the first end of the second support member being connected to the frame. The second clamping member is connected to the second end of the second support member, and / or the second clamping member is connected to the second end of the first support member.

[0013] Beneficial effects: The second support component connects to the frame, providing stable support for the clamping assembly and resisting external vibration interference (such as equipment operating vibration) during measurement. The second clamping component can be connected to either the second or first support component, adapting to the need for rapid changeover of parts to be measured of different sizes / shapes, and reducing tooling adjustment time.

[0014] In one optional embodiment, the driving member is configured as a first cylinder, which is rotatably connected to the second support member, such that the first cylinder swings relative to the second support member. The first clamping member is rotatably connected to the second support member and is adapted to swing relative to the second support member. The output end of the first cylinder is hinged to the first clamping member, and the end of the first clamping member is adapted to press against or disengage from the second surface of the part to be tested.

[0015] Beneficial effects: The first cylinder is rotatably connected to the second support, allowing the first clamping component to swing and conform to the irregular contours of the part to be tested (such as the curvature of a fender), avoiding localized deformation caused by rigid clamping. The first cylinder drive allows for precise adjustment of the clamping force, preventing damage to the part under test due to overpressure or instability due to underpressure. The pneumatic system operates quickly, shortening the clamping / release cycle and improving production line efficiency.

[0016] In one optional embodiment, the second detection element is adapted to detect the relative position of the part to be tested and the second clamping member. The second detection element is arranged in pairs with the second clamping member. The second detection element is connected to the second end of the second support member along its axial direction and facing the first surface, and / or the second detection element is connected to the second end of the first support member along its axial direction and facing the first surface.

[0017] Beneficial effects: The second detection element (such as a displacement sensor) directly monitors the relative position of the second clamping component and the part to be measured, providing real-time feedback on clamping anomalies (such as offset or loosening), avoiding measurement errors caused by clamping mistakes, and ensuring that the positioning component and the part to be measured reach the preset position. It also ensures that the second and first clamping components are properly clamped to the part. The detection data is fed back to the control system, dynamically adjusting the clamping force or position to achieve adaptive clamping and improve yield. The second detection element determines whether the clamping is in place, providing early warning of tooling malfunctions (such as cylinder failure) and reducing downtime.

[0018] In one optional embodiment, the end of the first clamping member is provided with a through hole, the abutting member passes through the through hole, and the axial position of the abutting member along the through hole is adjustable, the abutting member being adapted to abut against the second surface of the part to be tested.

[0019] Beneficial effects: The axial position of the abutment is adjustable to accommodate thickness differences caused by thermoforming variations in different batches of parts, eliminating the need to change tooling. Adjusting the extension length of the abutment ensures uniform clamping force distribution, preventing deformation of parts due to localized stress (such as cracking in brittle areas of aluminum alloy die-cast parts). The replaceable abutment design reduces replacement costs for worn parts and facilitates maintenance.

[0020] In one optional embodiment, the detection assembly includes a bracket, a first detection element, and a second cylinder. The bracket is rotatably connected to the frame and adapted to swing relative to the frame. The first detection element, adapted to detect the dimensional information of the part to be measured in the positioned state, is disposed on the bracket at an end away from the connection position between the bracket and the frame. The second cylinder is rotatably connected to the frame, and the output end of the second cylinder is rotatably connected to the bracket.

[0021] Beneficial effects: The bracket is rotatably connected to the frame, and driven by the second cylinder, the angle of the first detection element can be adjusted to cover different areas of the part, solving the blind spot problem of traditional fixed probes. During the swinging process, data is continuously collected through the first detection element (such as a laser scanning head), realizing continuous measurement of surface dimensions and improving detection efficiency. After the detection is completed, the second cylinder drives the bracket to reset, avoiding interference with subsequent processes (such as removing the measured part from the measuring device by a robotic arm).

[0022] In one optional implementation, an operation module is further included, connected to the frame, adapted to control the positioning component and the clamping component to position the part to be tested, and adapted to control the detection component to detect the dimensional information of the part to be tested in the positioned state.

[0023] Beneficial effects: The operation module integrates positioning, clamping, and detection commands, enabling "one-click" measurement and reducing human error. Simultaneously, it can synchronize detection information to the control system in the automatic cleaning line, generating real-time dimensional fluctuation trend charts to provide a basis for process parameter optimization. The operation module has built-in logic to detect clamping / positioning / detection abnormalities, automatically triggering alarms or shutdowns to reduce scrap rates.

[0024] Secondly, this application also provides an automatic cleaning line suitable for removing burrs from parts to be tested, including a measuring device and a deburring device. The measuring device positions and measures the parts to be tested. The deburring device is suitable for cleaning the parts to be tested after they have been positioned and measured.

[0025] Beneficial effects: The measuring device and deburring device are linked, realizing the integration of measurement and processing, avoiding the repetitive positioning errors caused by traditional separate operations. Measurement data directly guides deburring parameters (such as tool path and cutting amount), ensuring that deburring and dimensional correction are completed simultaneously, improving part consistency. It reduces intermediate handling and manual re-inspection, shortens the production cycle, and lowers overall costs. Attached Figure Description

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] The following is combined with Figures 1 to 7 This describes an embodiment of the present application.

[0038] According to an embodiment of this application, a measuring device is provided, suitable for positioning and measuring a part 1 to be measured. The part 1 has at least three positioning points 1003 arranged in a triangular pattern. The measuring device includes a frame 2, a positioning component 3, a clamping component 4, and a detection component 5. The positioning component 3 is disposed on the frame 2 and includes at least three positioning elements arranged in a triangular pattern, which are adapted to abut against the positioning points 1003 on the part 1 to be measured in a one-to-one correspondence. The clamping component 4 is adapted to clamp or release the part 1 to be measured. The detection component 5 is adapted to detect the dimensional information of the part 1 to be measured in the positioned state.

[0039] Understandable, such as Figure 6 As shown, at least three positioning points 1003 are set on the part to be tested 1, and the three positioning points 1003 are arranged in a triangle. This can achieve a relatively fixed position when the positioning component 3 is positioned at the positioning point 1003, thus avoiding relative displacement.

[0040] It should be noted that by positioning the component through the contact point 1003, the part to be tested 1 can reach a preset position, allowing it to coincide with a preset standard part model. This not only facilitates dimensional measurement but also enables the acquisition of the deviation value between the part to be tested 1 and the preset standard part, simplifying the subsequent deburring process. The clamping component 4 is used to clamp and fix the part to be tested 1 after positioning. When the part to be tested 1 is measured by the detection component 5, such as... Figure 3 As shown, the clamping assembly 4 is currently clamping the part 1 to be measured. When it is necessary to place the part 1 to be measured on the measuring device or to remove the part 1 after measurement for the next process, as shown... Figure 1 As shown, the clamping assembly 4 is detached from the part 1 to be tested at this time.

[0041] In this embodiment, the measuring device can position the part to be tested 1 using the positioning component 3. The positioning point 1003 on the part to be tested 1, in conjunction with the positioning component 3, enables the part to be tested 1 to reach a preset posture and achieve precise positioning within the measuring device. The clamping component 4 clamps and fixes the part to be tested 1 after positioning. The detection component 5 measures the part to be tested after positioning to obtain its dimensional information after precise positioning. The measuring device achieves integrated online positioning and measurement of the part to be tested 1, improving measurement efficiency.

[0042] In one embodiment, such as Figure 3 As shown, the positioning component includes a first support member 3002 and a spring pin 3003. The first support member 3002 has a first end facing the frame 2 and a second end facing the part to be tested 1. The first end of the first support member 3002 is connected to the frame 2. The spring pin 3003 is disposed at the second end of the first support member 3002, and the telescopic end of the spring pin 3003 abuts against the positioning point 1003 on the part to be tested 1.

[0043] Optionally, the first support member 3002 can be configured as a column structure, profile structure or frame structure, with its first end facing the frame 2 fixed to the frame 2 by bolts, and its second end facing the part to be tested 1 fixed to the spring pin 3003 by bolts.

[0044] Optionally, such as Figure 4 As shown, an auxiliary positioning component 3001 with an inclined side can also be set on the frame 2. The inclined side of the auxiliary positioning component 3001 can fit with the edge on the first surface 1001 of the part to be tested 1 and play a guiding role, ensuring that the positioning point 1003 can accurately abut against the spring pin 3003.

[0045] Optional, such as Figure 6 As shown, the first surface 1001 of the part to be tested is also provided with a limiting structure 1005 that is inserted into the telescopic end of the spring pin 3003. The limiting structure 1005 is specifically configured as two limiting members, and there is a gap between the two limiting members. The telescopic end of the spring pin 3003 is configured as a tapered structure with two opposite side walls inclined, which can be inserted into the gap for positioning. The tapered structure of the telescopic end of the spring pin 3003 can also play a guiding role.

[0046] In this embodiment, the telescopic end of the spring pin 3003 contacts the positioning point 1003 of the part to be tested 1, which can automatically compensate for minor dimensional deviations of the part to be tested 1 caused by thermal deformation or mold errors, ensuring that the positioning point 1003 is in close contact with the measuring device and reducing human adjustment errors. The spring buffer design avoids scratches on the surface of the part to be tested 1 due to rigid contact, and is especially suitable for integrated die-cast parts made of easily damaged materials such as aluminum alloy. The elastic pressure stabilizes and fixes the part to be tested 1, reducing dimensional fluctuations caused by loosening during the measurement process and ensuring the consistency of testing of multiple batches of the part to be tested 1.

[0047] In one embodiment, such as Figure 6 and Figure 7 As shown, the part to be tested 1 has a first surface 1001 and a second surface 1002 facing each other. The clamping assembly 4 includes a driving member 4003, a first clamping member 4001, and a second clamping member 4002. The first clamping member 4001 abuts against the second surface 1002, and the second clamping member 4002 abuts against the first surface 1001. The contact points between the first clamping member 4001 and the second surface 1002 and between the second clamping member 4002 and the first surface 1001 are located on opposite sides of the same position on the part to be tested 1. The output end of the driving member 4003 is connected to the first clamping member 4001. The driving member 4003 is adapted to drive the first clamping member 4001 to press against or disengage from the second surface 1002 of the part to be tested 1.

[0048] It is understandable that the first surface 1001 and the second surface 1002 of the part to be tested are two opposite sides of the part to be tested, so that when the first clamping member 4001 and the second clamping member 4002 clamp and fix the part to be tested, they can clamp the two opposite sides of the part to be tested, thereby ensuring the clamping and fixing effect of the part to be tested.

[0049] Optionally, such as Figure 6 and Figure 7 As shown, a clamping point 1004 is also provided on the part to be tested 1. The first clamping member 4001 and the second clamping member 4002 respectively abut against the two opposite positions of the clamping point 1004 on the part to be tested 1, thereby achieving precise clamping.

[0050] In this embodiment, the first clamping member 4001 abuts against the second surface 1002, and the second clamping member 4002 abuts against the first surface 1001, forming a symmetrical clamping force to prevent the part under test 1 from deforming (such as warping) due to unilateral pressure, ensuring that the part under test 1 is in a natural state during measurement. The clamping points 1004 are located on both sides of the same position of the part under test 1, which can effectively fix irregular structures (such as wheel covers, door frames) and avoid local stress concentration caused by traditional single-point clamping. The driving member 4003 controls the clamping members to press / release, reducing manual intervention and being compatible with the automated process of the production line.

[0051] In one embodiment, such as Figure 2 As shown, the clamping assembly 4 further includes a second support member 4004, which has a first end facing the frame 2 and a second end facing the part 1 to be tested. The first end of the second support member 4004 is connected to the frame 2. The second clamping member 4002 is connected to the second end of the second support member 4004, and / or the second clamping member 4002 is connected to the second end of the first support member 3002.

[0052] Optionally, the second support member 4004 can be configured as a column structure, profile structure or frame structure, and its first end facing the frame 2 is fixed to the frame 2 by bolts. The second clamping member 4002 can be bolted to its second end facing the part 1 to be measured or the second end of the first support member 3002 facing the part 1 to be measured.

[0053] In this embodiment, the second support member 4004 is connected to the frame 2 to provide stable support for the clamping assembly 4 and resist external vibration interference (such as equipment operation vibration) during the measurement process. The second clamping member 4002 can be selectively connected to the second support member 4004 or the first support member 3002 to adapt to the rapid changeover requirements of the parts to be measured 1 of different sizes / shapes and reduce tooling adjustment time.

[0054] In one embodiment, the driving member 4003 is configured as a first cylinder, which is rotatably connected to the second support member 4004, so that the first cylinder swings relative to the second support member 4004. The first clamping member 4001 is rotatably connected to the second support member 4004 and is adapted to swing relative to the second support member 4004. The output end of the first cylinder is hinged to the first clamping member 4001, and the end of the first clamping member 4001 is adapted to press or disengage from the second surface 1002 of the part to be tested 1.

[0055] Optionally, the drive component 4003 is bolted to the side wall of the second support component 4004. The drive component 4003 may also be equipped with a hydraulic cylinder or a linear module driven by a motor, ensuring that the output end of the drive component 4003 can extend and retract and swing relative to the second support component 4004.

[0056] Optionally, the driving component 4003 can also be a motor. The first clamping component 4001 and the second support component 4004 are rotatably connected by a rotating shaft. The output end of the motor is coaxially set with the rotating shaft, or the rotating shaft is controlled to rotate through a transmission assembly (gear set), thereby controlling the rotation of the first clamping component 4001, and finally controlling the first clamping component 4001 so that it can swing and clamp and fix the part 1 to be tested.

[0057] In this embodiment, the first cylinder is rotatably connected to the second support member 4004, allowing the first clamping member 4001 to swing and conform to the irregular contour of the part to be tested 1 (such as the curvature of a fender), avoiding local deformation caused by rigid clamping. The first cylinder drive can precisely adjust the clamping force, avoiding damage to the part to be tested 1 due to overpressure or instability due to underpressure. The pneumatic system operates quickly, shortening the clamping / release cycle and improving production line cycle efficiency.

[0058] In one embodiment, such as Figure 3 and Figure 4 As shown, the second detection element 4005 is adapted to detect the relative position of the part to be tested 1 and the second clamping member 4002. The second detection element 4005 and the second clamping member 4002 are arranged in pairs. The second detection element 4005 is connected to the second end of the second support member 4004 along its axial direction and toward the second end of the first surface 1001, and / or, the second detection element 4005 is connected to the second end of the first support member 3002 along its axial direction and toward the second end of the first surface 1001.

[0059] In this embodiment, the second detection element 4005 (such as a displacement sensor) directly monitors the relative position of the second clamping member 4002 and the part 1 to be tested, providing real-time feedback on any clamping status abnormalities (such as offset or loosening), avoiding measurement errors caused by clamping mistakes, and ensuring that the positioning component 3 and the part 1 to be tested reach the preset position. It also ensures that the second clamping member 4002 and the first clamping member 4001 are properly clamped to the part 1. The detection data is fed back to the control system, dynamically adjusting the clamping force or position to achieve adaptive clamping and improve yield. The second detection element 4005 determines whether the clamping is in place, providing early warning of tooling failures (such as cylinder failure) and reducing downtime.

[0060] In one embodiment, the end of the first clamping member 4001 is provided with a through hole, the abutment member 4006 passes through the through hole, and the axial position of the abutment member 4006 along the through hole is adjustable. The abutment member 4006 is adapted to abut against the second surface 1002 of the part to be tested 1.

[0061] It should be noted that, as Figure 2 As shown, the abutment member 4006 includes an abutment post that passes through a through hole and is threadedly connected to the through hole. A limiting nut is fitted on the outer side of the abutment post, which is threadedly connected to the abutment post and abuts against the second support member 4004, thus achieving a stable connection between the abutment post and the first clamping member 4001. Simultaneously, the abutment post and the end of the part to be tested 1 are provided with an abutment portion, the cross-sectional area of ​​which is perpendicular to its axial direction is larger than the cross-sectional area of ​​the rest of the abutment post.

[0062] Optionally, the middle part of the first clamping member 4001 is hinged to the second support member 4004, the first end of the first clamping member 4001 is provided with an abutment member 4006, the second end of the second clamping member 4002 is rotatably connected to the output end of the drive member 4003, and the first end and the second end of the first clamping member 4001 are respectively at the two ends of the hinged position.

[0063] In this embodiment, the axial position of the abutment 4006 is adjustable to accommodate thickness differences caused by thermoforming fluctuations in different batches of parts, eliminating the need to change tooling. By adjusting the extension length of the abutment 4006, uniform clamping force distribution is ensured, preventing deformation of parts due to localized stress (such as cracking in brittle areas of aluminum alloy die-cast parts). The replaceable design of the abutment 4006 reduces the cost of replacing worn parts and facilitates maintenance.

[0064] In one embodiment, such as Figure 1 and Figure 5 As shown, the detection assembly 5 includes a bracket 5001, a first detection element 5002, and a second cylinder 5003. The bracket 5001 is rotatably connected to the frame 2 and is adapted to swing relative to the frame 2. The first detection element 5002 is adapted to detect the dimensional information of the part 1 to be measured in the positioned state, and the first detection element 5002 is disposed on the bracket 5001 at one end away from the connection position between the bracket 5001 and the frame 2. The second cylinder 5003 is rotatably connected to the frame 2, and the output end of the second cylinder 5003 is rotatably connected to the bracket 5001.

[0065] Understandably, the output end of the second cylinder 5003 is in an extended state when the part to be tested 1 is not loaded or when it needs to be removed, which allows the bracket 5001 to be in a position close to the frame 2, facilitating the loading or unloading of the part to be tested 1. When the part to be tested 1 is being tested, the output end of the second cylinder 5003 is in a retracted state, which allows the bracket 5001 to gradually move closer to the part, thereby achieving all-round testing of the part to be tested 1.

[0066] Optionally, multiple first detection elements 5002 may be provided, and they may be spaced apart along a straight line or evenly distributed on the bracket 5001.

[0067] In this embodiment, the bracket 5001 is rotatably connected to the frame 2 and driven by the second cylinder 5003. This allows adjustment of the angle of the first detection element 5002, covering different areas of the part and solving the blind spot problem of traditional fixed probes. During the swinging process, data is continuously collected through the first detection element 5002 (such as a laser scanning head), enabling continuous measurement of the surface dimensions and improving detection efficiency. After the detection is completed, the second cylinder 5003 drives the bracket 5001 to reset, avoiding interference with subsequent processes (such as removing the measured part 1 from the measuring device using a robotic arm).

[0068] In one embodiment, such asFigure 1 As shown, it also includes an operation module 6, which is connected to the frame 2 and is adapted to control the positioning component 3 and the clamping component 4 to position the part to be tested 1, and is adapted to control the detection component 5 to detect the size information of the part to be tested 1 in the positioned state.

[0069] Optionally, the operation module 6 is connected to the control system signal of the automatic cleaning line, enabling signal transmission between them and sending and receiving operation commands.

[0070] In this embodiment, the operation module 6 integrates positioning, clamping, and detection commands to achieve "one-click" measurement and reduce human error. Simultaneously, it can synchronize detection information to the control system in the automatic cleaning line, generating a real-time dimensional fluctuation trend chart to provide a basis for process parameter optimization. The operation module 6 has built-in logic to detect clamping / positioning / detection abnormalities, automatically triggering alarms or stopping the machine to reduce the scrap rate.

[0071] According to an embodiment of this application, another aspect provides an automatic cleaning line suitable for removing burrs from a part 1 to be tested, including a measuring device and a deburring device. The measuring device positions and measures the part 1 to be tested. The deburring device is suitable for cleaning the part 1 after it has been positioned and measured.

[0072] In this embodiment, the measuring device and the deburring device are linked to achieve integrated measurement and processing, avoiding repetitive positioning errors caused by traditional separate operations. Measurement data directly guides deburring parameters (such as tool path and cutting amount), ensuring that deburring and dimensional correction are completed simultaneously, improving part consistency. Reducing intermediate handling and manual inspection steps shortens the production cycle and lowers overall costs.
