Description

Technical Field

[0001] This invention relates to the field of automotive parts inspection technology, specifically to an automatic inspection fixture for automotive side return. Background Technology

[0002] When inspecting automotive parts, a large amount of manual labor is required to perform data testing on the parts. Different data require different operators, and different testing tools are used. This results in a significant amount of manpower being consumed after the parts have undergone data testing by operators, which reduces the efficiency of automotive parts inspection.

[0003] Most automotive parts are irregular geometric shapes. In addition, manual operation is too cumbersome when inspecting the angles of different curved surfaces. When positioning automotive parts, the position of the parts needs to be manually checked, which increases the inspection time and labor costs of automotive inspection. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic inspection fixture for vehicle side return to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] An automatic vehicle side return detection fixture includes a frame, vehicle components, a limit module, a detection mechanism, and a positioning mechanism;

[0007] The frame is horizontally arranged, and a car component is provided on the top of the frame. Several limiting modules are arranged in a ring around the top of the frame about the car component. A detection mechanism is provided on one side of the limiting module. A positioning mechanism is provided between the frame and the car component.

[0008] The frame includes a support base plate with leveling feet at its bottom. The tops of the leveling feet are threaded to the support base plate. A support platform is located on the upper surface of the support base plate. Several limit rods are provided around the top of the support platform. A positioning panel is located at the center of the top of the support platform. A positioning cylinder is located on the upper surface of the positioning panel. A car component is positioned on top of the positioning cylinder and connected to the positioning cylinder through a through hole at its bottom. The leveling feet at the bottom of the support base plate adjust its level to prevent wobbling during testing. The positioning cylinder is then connected to the car component through the through hole, limiting lateral movement. The limit rods on the support platform assist the operator in placing the car component, allowing for quick and easy positioning and preventing it from slipping, thus ensuring its safety.

[0009] The limiting module includes a support column, the bottom of which is connected to the upper surface of a support base plate. A connecting base plate is provided at the top of the support column. A rotating rod is hinged to the upper surface of the connecting base plate. A movable side plate is hinged to one end of the rotating rod. A guide sleeve is provided on the side of the connecting base plate away from the rotating rod. A top rod is provided on the inner wall of the guide sleeve. One end of the top rod is hinged to the movable side plate. A locking block is provided at the other end of the top rod. An abutting locking rod is provided at the top of the locking block. A buffer spring is provided at one end of the abutting locking rod. A rubber-plastic protrusion is provided at the end of the abutting locking rod near the buffer spring. Pulling the rotating rod causes it to deflect along one side of the connecting base plate. Simultaneously, the deflection of the rotating rod moves the movable side plate, causing the side of the movable side plate away from the rotating rod to push the push rod along the inner wall of the guide sleeve. This allows the push rod to be pushed out when the rotating rod is deflected downwards. Simultaneously, the push rod moves the abutment lever on one end of the locking block, causing the abutment lever to contact the side of the automotive part via a rubber-plastic protrusion at one end. The abutment lever compresses the buffer spring for cushioning, limiting the position of the automotive part, reducing its shaking, and improving the accuracy of data detection.

[0010] The detection mechanism includes a positioning slide rail, the bottom of which is connected to a supporting base plate. The positioning slide rail is located on one side of the supporting column, and a contact sensor is installed on one side of the positioning slide rail. A sliding plate is installed on the inner wall of the positioning slide rail, and a groove is formed on the upper surface of the sliding plate. A positioning screw is installed on the sliding plate through the groove. A detection sensor is installed on the side of the sliding plate away from the positioning screw. The bottom end of the sliding plate is hinged to the inner wall of the positioning slide rail. By twisting the positioning screw, the position of the sliding plate on the positioning slide rail is adjusted. Rotating the positioning screw along one side of the sliding plate causes the bottom end of the positioning screw to contact the inner wall of the positioning slide rail, causing one side of the sliding plate to deflect. One side of the sliding plate is set with a flat angle, so that while the sliding plate is deflecting, it connects to one end of the contact sensor through the inclined surface set with the flat angle. The deflection angle of the sliding plate is obtained according to the contraction length of the contact sensor. At the same time, the position between the detection sensor and the automotive component is adjusted, improving the applicability of this device.

[0011] The positioning mechanism includes a connecting rod, the bottom end of which is connected to a positioning panel. A movable spring is located at the bottom of the connecting rod, and its bottom is also connected to the positioning panel. A movable base plate is located at the top of the movable spring. A fixed side plate is located on the upper surface of the movable base plate, and a pull rod is located on one side of the fixed side plate. A top block is located at the top of the connecting rod, and a sliding block is located inside the top block. The bottom of the automotive component is connected to the movable base plate. When positioning and placing the automotive component, it is positioned through a through-hole. The automotive component is then fitted with the top block through the through-hole, causing the connecting rod to contact the inner wall of the through-hole on the automotive component, guiding the downward direction of the component. Simultaneously, the movable base plate supports the automotive component, and the compression of the movable spring by the movable base plate cushions the downward movement of the automotive component, ensuring smooth contact with the positioning panel and reducing wear from collisions.

[0012] One end of the connecting rod has a circumferential groove. The fixed side plate is connected to the connecting rod through the groove. Three fixed side plates are provided, equidistantly distributed in a ring around the connecting rod. One side of each fixed side plate has an inclined slot. The bottom end of the pull rod is connected to the fixed side plate through the inclined slot, and the top end of the pull rod engages with the top block. When the car part is lowered, the movable base plate is pressed, causing it to slide the fixed side plate downwards along the groove at one end of the connecting rod. As the fixed side plate slides downwards, it moves the pull rod through the inclined slot. The top end of the pull rod engages with the top block, causing the pull rod to push outwards and engage with the inner wall of the through hole on the car part. This fixes the position of the car part, limits its vertical angular sway, and further improves the accuracy of the car part's inspection data.

[0013] The top of the top block is angled, and the top of the pull rod is connected to the abutting slider. As the top of the pull rod moves outward from inside the top block, the abutting slider inside the top block falls, causing it to abut against the top of the pull rod, preventing the pull rod from moving in the opposite direction. When the car part needs to be removed, the abutting slider is pulled up, causing the movable spring to push the movable base plate upward. The movable base plate pushes the car part upward, and simultaneously, the movable base plate moves the fixed side plate upward. The fixed side plate then causes the top of the pull rod to tighten, releasing the connection between the pull rod and the car part. At the same time, the movable spring assists the operator in pushing the car part upward, disengaging it from the positioning cylinder, making it easier for the operator to remove the car part and improving the operator's work efficiency.

[0014] Two positioning cylinders are provided, equidistantly distributed in a ring around the positioning mechanism. The tops of the positioning cylinders are rounded, and the horizontal height of the top block is higher than that of the positioning cylinders. When placing the automotive component, its angle needs to be adjusted. The movable base plate in the positioning mechanism provides auxiliary support for the automotive component, which is then rotated around the connecting rod to adjust its angle. This saves labor costs for operators and further improves their work efficiency.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0016] 1. The frame, vehicle components, and limiting module design allow users to easily control the horizontal position of the vehicle components via a pull rod. By controlling the deflection angle of the pull rod, the degree of contact between the contact lever and the vehicle components is adjusted. This allows the limiting module to protect the edges of the vehicle components from contact, preventing elastic deformation of the plate-shaped vehicle components during testing and compression. This reduces the impact of deformation on the test data, ensuring the accuracy of the test data and improving the precision of the device.

[0017] 2. The setup of the frame, automotive parts, limit module, and detection mechanism facilitates users to quickly detect multiple measurement data on automotive parts. By adjusting the position of the slide plate within the positioning slide rail and adjusting the position of the detection sensor according to the size of the automotive part, the detection is then performed by pushing out the pneumatic rod head of multiple detection sensors. This improves the automation level of the device, saves the user's operation time, and enhances the working efficiency of the device.

[0018] 3. The design, including the frame, vehicle parts, limit module, detection mechanism, and positioning mechanism, allows users to quickly fix the position of the vehicle parts. The movable base plate in the positioning mechanism provides auxiliary support for the vehicle parts, allowing them to deflect around the connecting rod. Adjusting the deflection angle of the vehicle parts saves on operator labor. Pulling up the sliding block causes the movable spring to push the movable base plate upwards, which in turn pushes the vehicle parts upwards. Simultaneously, the movable base plate moves the fixed side plate upwards, which in turn causes the top of the pull rod to tighten and move, releasing the pull rod from the vehicle parts. At the same time, the movable spring assists the operator in pushing the vehicle parts upwards, disengaging them from the positioning cylinder, making it easier for the user to pick up the vehicle parts and further improving the working efficiency of the device.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1-12 The present invention provides the following technical solution:

[0040] An automatic vehicle side return detection fixture includes a frame 1, a vehicle component 2, a limit module 3, a detection mechanism 4, and a positioning mechanism 5;

[0041] The frame 1 is horizontally set, and the top of the frame 1 is equipped with a car component 2. Several limiting modules 3 are distributed in a ring around the top of the frame 1 about the car component 2. A detection mechanism 4 is set on one side of the limiting module 3. A positioning mechanism 5 is set between the frame 1 and the car component 2.

[0042] The frame 1 includes a support base plate 101. The bottom of the support base plate 101 is provided with a leveling support foot 102. The top of the leveling support foot 102 is threadedly connected to the support base plate 101. The upper surface of the support base plate 101 is provided with a support platform 103. The top of the support platform 103 is provided with limit rods 104 around its perimeter. Several limit rods 104 are provided. The center of the top of the support platform 103 is provided with a positioning panel 105. The upper surface of the positioning panel 105 is provided with a positioning cylinder 106. The top of the positioning cylinder 106 is provided with an automobile component 2. The automobile component 2 is connected to the positioning cylinder 106 through a through hole at the bottom. The leveling feet 102 at the bottom of the support base plate 101 are used to adjust the level of the support base plate 101, preventing the support base plate 101 from shaking during testing. Then, according to the through holes provided on the car component 2, the positioning cylinder 106 is connected to the car component 2 to limit the lateral sway of the car component 2. At the same time, the limiting rod 104 on the support platform 103 assists the operator in placing the car component 2. The limiting rod 104 makes it easy for the operator to quickly determine the position of the car component 2, and at the same time, it prevents the car component 2 from slipping, ensuring the safety of the car component 2.

[0043] The limiting module 3 includes a support column 301. The bottom of the support column 301 is connected to the upper surface of the support base plate 101. A connecting base plate 302 is provided at the top of the support column 301. A rotating rod 303 is hinged to the upper surface of the connecting base plate 302. A movable side plate 304 is hinged to one end of the rotating rod 303. A guide sleeve 305 is provided on the side of the connecting base plate 302 away from the rotating rod 303. A push rod 306 is provided on the inner wall of the guide sleeve 305. One end of the push rod 306 is hinged to the movable side plate 304. A locking block 307 is provided at the other end of the push rod 306. An abutting locking rod 309 is provided at the top of the locking block 307. A buffer spring 308 is provided at one end of the abutting locking rod 309. A rubber and plastic protrusion is provided at the end of the abutting locking rod 309 near the buffer spring 308. Pulling the rotating rod 303 causes it to deflect along one side of the connecting base plate 302. Simultaneously, the deflection of the rotating rod 303 moves the movable side plate 304, causing the side of the movable side plate 304 away from the rotating rod 303 to push the top rod 306 along the inner wall of the guide sleeve 305. This allows the top rod 306 to be pushed out when the rotating rod 303 is deflected downwards. Simultaneously, the push rod 306 moves the abutting rod 309 on one end of the locking block 307, causing the abutting rod 309 to abut against the side of the automotive component 2 via a rubber-plastic protrusion at one end. The abutting rod 309 compresses the buffer spring 308 for cushioning, limiting the position of the automotive component 2, reducing its shaking, and improving the accuracy of data detection.

[0044] The detection mechanism 4 includes a positioning slide rail 401. The bottom of the positioning slide rail 401 is connected to the support base plate 101. The positioning slide rail 401 is located on one side of the support column 301. A contact sensor 402 is provided on one side of the positioning slide rail 401. A slide plate 403 is provided on the inner wall of the positioning slide rail 401. A groove is provided on the upper surface of the slide plate 403. A positioning screw 404 is provided on the slide plate 403 through the groove. A detection sensor 405 is provided on the side of the slide plate 403 away from the positioning screw 404. The bottom end of the slide plate 403 is hinged to the inner wall of the positioning slide rail 401. The position of the slide plate 403 on the positioning slide rail 401 is adjusted by twisting the positioning screw 404. The positioning screw 404 is rotated along one side of the slide plate 403, and the bottom end of the positioning screw 404 abuts against the inner wall of the positioning slide rail 401, causing one side of the slide plate 403 to deflect. One side of the slide plate 403 is set with a flat angle, so that while the slide plate 403 is deflected, it connects with one end of the contact sensor 402 through the inclined surface set with the flat angle. The deflection angle of the slide plate 403 is obtained according to the contraction length of the contact sensor 402. At the same time, the position between the detection sensor 405 and the automobile component 2 is adjusted, which improves the applicability of this device.

[0045] The positioning mechanism 5 includes a connecting rod 501, the bottom end of which is connected to the positioning panel 105. A movable spring 502 is provided at the bottom of the connecting rod 501, and the bottom of the movable spring 502 is connected to the positioning panel 105. A movable base plate 503 is provided at the top of the movable spring 502. A fixed side plate 504 is provided on the upper surface of the movable base plate 503. A pull rod 505 is provided on one side of the fixed side plate 504. A top block 506 is provided at the top of the connecting rod 501. An abutment slider 507 is provided inside the top block 506. The bottom of the automotive component 2 is connected to the movable base plate 503. When positioning and placing the car component 2, it is positioned through the through hole opened on the car component 2. The car component 2 is connected to the top block 506 through the through hole, so that the connecting rod 501 is connected to the inner wall of the through hole on the car component 2, guiding the downward direction of the car component 2. At the same time, the movable base plate 503 supports the car component 2. The movable base plate 503 compresses the movable spring 502 to buffer the downward movement of the car component, so that the car component 2 makes stable contact with the positioning panel 105, reducing the wear of the car component 2 due to collision.

[0046] One end of the connecting rod 501 has a strip groove in the ring. The fixed side plate 504 is connected to the connecting rod 501 through the strip groove. There are three fixed side plates 504, which are equidistantly distributed in the ring around the connecting rod 501. One side of the fixed side plate 504 has an inclined slot. The bottom end of the pull rod 505 is connected to the fixed side plate 504 through the inclined slot. The top end of the pull rod 505 is engaged with the top block 506. As the car component 2 is lowered, the movable base plate 503 is pressed, causing the movable base plate 503 to drive the fixed side plate 504 to slide downward along the strip groove at one end of the connecting rod 501. As the fixed side plate 504 slides downward, it drives the pull rod 505 to move through the inclined slot. The top of the pull rod 505 engages with the top block 506, causing the pull rod 505 to push outward and engage with the inner wall of the through hole on the car component 2, fixing the position of the car component 2, limiting the vertical sway of the car component 2, and further improving the accuracy of the data detected by the car component 2.

[0047] The top of the top block 506 is set with a flat angle, and the top of the pull rod 505 is connected to the abutting slider 507. As the top of the pull rod 505 moves outward inside the top block 506, the abutting slider 507 inside the top block 506 falls, causing the abutting slider 507 to abut against the top of the pull rod 505, preventing the pull rod 505 from moving in the opposite direction. When the car part 2 needs to be removed, the abutting slider 507 is pulled upward, causing the movable spring 502 to push the movable base plate 503 upward. The movable base plate 503 pushes the car part 2 upward, and simultaneously, the movable base plate 503 drives the fixed side plate 504 upward. The fixed side plate 504 causes the top of the pull rod 505 to tighten and move, releasing the pull rod 505 from the car part 2. At the same time, the movable spring 502 assists the operator in pushing the car part 2 upward, disengaging it from the positioning cylinder 106, making it easier for the operator to pick up the car part 2 and improving the operator's work efficiency.

[0048] Two positioning cylinders 106 are provided, equidistantly distributed in a ring around the positioning mechanism 5. The tops of the positioning cylinders 106 are rounded, and the horizontal height of the top block 506 is higher than that of the positioning cylinders 106. When placing the car component 2, its angle needs to be adjusted. The movable base plate 503 in the positioning mechanism 5 provides auxiliary support for the car component 2. Then, the car component 2 is rotated around the connecting rod 501 to adjust its angle, saving operator labor and further improving operator efficiency.

[0049] Working principle of the invention:

[0050] First, the car part 2 needs to be placed on the frame 1. The car part 2 has a through hole. The car part 2 is connected to the top block 506 through the through hole, so that the connecting rod 501 is connected to the inner wall of the through hole on the car part 2, guiding the downward direction of the car part 2. At the same time, the movable base plate 503 supports the car part 2. The movable base plate 503 compresses the movable spring 502 to buffer the downward movement of the car part, so that the car part 2 makes stable contact with the positioning panel 105, reducing the wear of the car part 2 due to collision.

[0051] During the process of lowering the car component 2, the angle of the car component 2 needs to be adjusted. The movable base plate 503 in the positioning mechanism 5 provides auxiliary support for the car component 2, and the top of the positioning cylinder 106 provides auxiliary support for the car component 2. Then, the car component 2 is deflected around the connecting rod 501 to adjust the angle of the car component 2 so that the through hole on the car component 2 is engaged with the positioning cylinder 106.

[0052] Once the angle of the car component 2 is determined, stabilize the position of the car component 2 and press the movable base plate 503 while lowering the car component 2. This causes the movable base plate 503 to drive the fixed side plate 504 to slide downward along the strip groove at one end of the connecting rod 501. As the fixed side plate 504 slides downward, it drives the pull rod 505 to move through the inclined slot. The top of the pull rod 505 engages with the top block 506, causing the pull rod 505 to push outward and engage with the inner wall of the through hole on the car component 2, thus fixing the position of the car component 2 and limiting the vertical sway of the car component 2. As the top of the pull rod 505 moves outward inside the top block 506, the abutting slider 507 inside the top block 506 falls, causing the abutting slider 507 to abut with the top of the pull rod 505, thus preventing the pull rod 505 from moving in the opposite direction.

[0053] After the position of the car component 2 is determined, the rotating rod 303 is pulled, causing the rotating rod 303 to deflect along one side of the connecting base plate 302. At the same time as the rotating rod 303 deflects, it drives the movable side plate 304 to move. The side of the movable side plate 304 away from the rotating rod 303 pushes the top rod 306 to move along the inner wall of the guide sleeve 305. When the rotating rod 303 is deflected downward, the top rod 306 can be pushed out. At the same time as the top rod 306 is pushed out, it drives the abutting rod 309 on one end of the locking block 307 to move. The abutting rod 309 abuts against the side of the car component 2 through the rubber and plastic protrusion provided at one end. The abutting rod 309 compresses the buffer spring 308 for buffering and restricts the position of the car component 2. This allows the limiting module 3 to protect the edge of the car component 2 from contact, reducing the deformation and deflection of the car component 2 when the detection sensor 405 detects contact, which may affect the detection data.

[0054] Subsequently, the dimensional data of the car component 2 is detected. The position of the slide plate 403 on the positioning slide rail 401 is adjusted by twisting the positioning screw 404. The positioning screw 404 is rotated along one side of the slide plate 403, and the bottom end of the positioning screw 404 abuts against the inner wall of the positioning slide rail 401, causing one side of the slide plate 403 to deflect. One side of the slide plate 403 is set with a flat angle, so that the slide plate 403 connects with one end of the contact sensor 402 through the inclined surface set with the flat angle while deflecting. The deflection angle of the slide plate 403 is obtained according to the contraction length of the contact sensor 402. The position between the detection sensor 405 and the car component 2 is adjusted. The data detection of the car component 2 is performed by pushing the cylinder inside the detection sensor 405.

[0055] After the inspection is completed, the car part 2 needs to be removed. Pull the rotating rod 303 in the opposite direction to release the connection between the contact lever 309 and the car part 2. Pull the contact slider 507 upward, so that the movable spring 502 pushes the movable base plate 503 upward. The movable base plate 503 pushes the car part 2 upward. At the same time, the movable base plate 503 drives the fixed side plate 504 to move upward. The fixed side plate 504 drives the top of the pull rod 505 to tighten and move, releasing the connection between the pull rod 505 and the car part 2. At the same time, the movable spring 502 assists the operator to push the car part 2 upward and disengage it from the positioning cylinder 106, so that the car part 2 can be quickly removed.
