Description

Technical Field

[0001] This invention relates to the field of automotive inspection tools, and more specifically to an inspection tool for vehicle body wiring harness brackets. Background Technology

[0002] The dimensional accuracy of automotive parts directly affects the assembly quality and safety performance of the entire vehicle. Therefore, during the production process, specialized inspection fixtures are needed to inspect key dimensions such as contour and cut edge position. As an inspection tool that simulates the actual assembly state, the core function of the inspection fixture is to provide reliable positioning and clamping for the automotive parts and to provide a measurement benchmark for the inspection tools.

[0003] Patent document CN202521709895.6 discloses a contour inspection tool for automotive parts, including a frame and a go / no-go gauge. The frame is equipped with a placement block, a lower profile block, a side profile block, and an upper profile block. The placement block has a positioning pin, and the frame has quick-clamping clamps corresponding to the positioning pins. The quick-clamping clamps have pressure blocks, and the quick-clamping clamps are used to drive the pressure blocks to press the automotive parts. The go / no-go gauge is used to inspect the contour of the automotive parts. When the automotive parts are placed on the lower profile block, the positioning pins and pressure blocks cooperate to limit the position of the automotive parts relative to the profile blocks, reducing the deviation of the automotive parts' position relative to the profile blocks and improving the inspection effect. It can be seen that in the prior art, by setting flip blocks or push-pull blocks, interference is avoided during the workpiece positioning, installation, or removal process, and it is convenient to perform the inspection of specified features after the workpiece is positioned.

[0004] The vehicle wiring harness bracket is a stamped part, which includes panels in at least two directions, and connecting bolts are provided on one side panel as needed. When inspecting such workpieces, the positional accuracy of the bolts is a key inspection feature. However, due to the stamping accuracy or the stress on the workpiece after stamping, the bending angle of the two panels is within a certain range, which affects the posture of the bolts after they are positioned on the workpiece and the gauge. This may interfere with the stroke of the push-pull inspection block, especially causing the edges of the inspection block to rigidly collide with the workpiece, thus affecting the fitting accuracy between the inspection block and the gauge block. Therefore, there is an urgent need for an inspection fixture for vehicle wiring harness brackets to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a fixture for vehicle body wiring harness brackets to address the aforementioned shortcomings in the prior art.

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

[0007] A fixture for inspecting vehicle wiring harness brackets, the wiring harness bracket comprising a first panel and a second panel bent into one piece, the second panel having a bolt extending along its normal direction fixed thereon; the fixture comprising: a base; a testing platform disposed on the base, the testing platform having a first positioning surface for positioning the first panel, the normal direction of the first positioning surface being a first direction, the normal direction of the second panel being a second direction when the first panel is positioned on the first positioning surface, the angle between the first direction and the second direction being within a preset range; a clamping assembly for fixing the first panel to the first positioning surface; a testing block having a testing angle for engaging with the bolt to detect the bolt's positional accuracy, the testing block being movable along a third direction, the third direction being perpendicular to both the first direction and the second direction; and a guiding mechanism configured to: as the testing block moves toward the bolt along the third direction, guide the testing block to also move away from and then toward the bolt in the first direction.

[0008] Preferably, the guiding mechanism includes a guide seat fixed on the base and a push-pull rod movably disposed within the guide seat along the third direction, one end of the push-pull rod being fixedly connected to the detection block.

[0009] Preferably, the guide seat is provided with a guide groove adapted to the push-pull rod. The push-pull rod can also rotate around a first rotating axis in the guide groove. The first rotating axis is perpendicular to the first direction and a third direction. When the push-pull rod is parallel to the third direction in its length direction, it enters the detection posture.

[0010] Preferably, the guide groove is provided with a fulcrum, a reference portion, and a thrust assembly that cooperate with the push-pull rod. The fulcrum provides the first rotating shaft. The fulcrum and the thrust assembly are arranged at different positions in the third direction. The reference portion is configured to cause the push-pull rod to enter the detection posture by abutting against it. The push-pull rod is provided with a thrust area that slides with the thrust assembly. A groove is provided in the thrust area. The thrust area is configured such that when the thrust assembly passes through the thrust area, the push-pull rod abuts against the reference portion. The groove is configured such that when the thrust assembly passes through the groove, the detection corner is adjacent to the bolt, and the push-pull rod moves away from the reference portion before abutting against it.

[0011] Preferably, the fulcrum is a first protrusion, which is disposed on the inner wall of the guide groove.

[0012] Preferably, the fulcrum is a sliding shaft and a sliding groove that are in sliding fit, one of which is disposed on the push-pull rod and the other is disposed on the inner wall of the guide groove.

[0013] Preferably, the reference portion is a second protrusion, which is disposed on the inner wall of the guide groove.

[0014] Preferably, the guide seat is provided with a guide hole along the first direction, and the push-pull rod is provided with at least one positioning hole that matches the guide hole. The positioning hole is configured such that when the detection corner is engaged with the bolt and the push-pull rod is in the detection posture, the guide hole and the positioning hole are coaxially aligned and the same pin is inserted; otherwise, the pin cannot be inserted into the positioning hole.

[0015] Preferably, the clamp assembly includes a pressure arm hinged to the base along an axis perpendicular to the first direction, so that the pressure arm can switch between a pressing state and a lifting state. A pressure block is connected to the pressure arm via an adjustment assembly, and a reference block that cooperates with the pressure block is provided on the detection table.

[0016] Preferably, the adjusting component consists of two screws arranged along the length of the pressure arm. The screws are movably arranged relative to the pressure arm within a preset stroke along a fourth direction. The fourth direction is perpendicular to the rotation axis of the pressure arm. The fourth direction is also configured such that when the pressure arm is in a depressed state, the fourth direction is parallel to the first direction. Nuts are provided at both ends of the screws on both sides of the pressure arm.

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

[0018] The inspection tool for the vehicle body wiring harness bracket is equipped with a guide mechanism. After the vehicle body wiring harness bracket is fixed to the first positioning surface of the inspection table by the clamp assembly with the first panel, the inspection block moves toward the bolt in a third direction. During this process, the guide mechanism guides the inspection block to move away from the bolt in the first direction, thereby avoiding the bolt position fluctuation range caused by the included angle between the first panel and the second panel being within a preset range. Then, the guide mechanism continues to guide the inspection block to move closer to the bolt in the first direction. As a result, the inspection block comes into close contact with the bolt with the inner wall of the inspection corner. At this time, even if the bolt interferes with the inspection block, it will only slightly collide with the inner wall of the inspection corner and will not affect the fitting accuracy between the inspection block and the gauge block.

[0019] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

Detailed Implementation

[0032] 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.

[0033] Please see Figure 1-8 This invention provides a fixture for inspecting a vehicle body wiring harness bracket. The wiring harness bracket includes a first panel 1 and a second panel 2 bent into one piece. A bolt 3 extending along the normal direction is fixed on the second panel 2. The fixture includes: a base 4; a testing platform 5 disposed on the base 4, the testing platform 5 having a first positioning surface for positioning the first panel 1, the normal direction of the first positioning surface being a first direction, and when the first panel 1 is positioned on the first positioning surface, the normal direction of the second panel 2 being a second direction, the angle between the first direction and the second direction being within a preset range; a clamping assembly for fixing the first panel 1 on the first positioning surface; a testing block 6 having a testing angle for cooperating with the bolt 3 to detect the position of the bolt 3, the testing block 6 being movable along a third direction, the third direction being perpendicular to both the first and second directions; and a guiding mechanism configured to guide the testing block 6 to move away from and then towards the bolt 3 in the first direction during the movement of the testing block 6 towards the bolt 3 along the third direction.

[0034] Compared with the prior art, the inspection tool for the vehicle body wiring harness bracket proposed in this embodiment of the invention, by setting a guiding mechanism, after the vehicle body wiring harness bracket is fixed to the first positioning surface on the inspection table 5 by the first panel 1 through the clamp assembly, the inspection block 6 moves toward the bolt 3 in a third direction. During this process, the guiding mechanism guides the inspection block 6 to move away from the bolt 3 in the first direction, thereby avoiding the position fluctuation range of the bolt 3 caused by the included angle between the first panel 1 and the second panel 2 being within a preset range. Then, the guiding mechanism continues to guide the inspection block 6 to move closer to the bolt 3 in the first direction. Thus, the inspection block 6 is close to the bolt 3 with the inner wall of the inspection corner. At this time, even if the bolt 3 and the inspection block 6 interfere, they only slightly collide with the inner wall of the inspection corner, which will not affect the fitting accuracy of the inspection block 6 and the gauge block.

[0035] Specifically, the arrangement of the base 4 affects the determination of various references on it. Preferably, when the base 4 is used horizontally, the first positioning surface is horizontal and the first direction is vertical; when the base 4 is used at an angle, the first positioning surface is inclined and the first direction is perpendicular to the inclined surface. The inspection table 5 includes at least a first module and a second module, which are set separately and a gap is maintained between them when they are combined. This combination facilitates production and adjustment during assembly. The first module is provided with at least a first inspection surface that is adapted to the first panel 1, and the second module is provided with at least a second inspection surface that is adapted to the second panel 2. The combination of the first and second inspection surfaces can cover all the surfaces to be inspected and the cut edges on the vehicle body wire harness bracket. The inspection table 5 is also provided with multiple inspection holes, which correspond one-to-one with the openings on the wire harness bracket. There are no fewer than two sets of clamp assemblies. Before the first panel 1 is fixed by the clamp assemblies, it is positioned on the first positioning surface by passing through the designated openings on the wire harness bracket with no fewer than two positioning pins. The detection inside corner is set on the detection block 6 near the corner of the bolt 3; the detection inside corner is a right angle. After the detection inside corner and the bolt 3 are fitted together, there should be a gap between the two right-angled sides of the detection inside corner and the outer wall of the bolt 3. The position of the bolt 3 is determined by checking the gap with a block-shaped go / no-go gauge.

[0036] As a preferred embodiment, the guiding mechanism includes a guide seat 12 fixed on the base 4 and a push-pull rod 13 movably disposed within the guide seat 12 along a third direction. One end of the push-pull rod 13 is fixedly connected to the detection block 6. The guide seat 12 is provided with a guide groove 14 adapted to the push-pull rod 13. The push-pull rod 13 can also rotate around a first axis within the guide groove 14. The first axis is perpendicular to both the first direction and the third direction. When the push-pull rod 13 is parallel to the third direction in its length direction, it enters the detection posture. Specifically, the plane intersecting the length direction of the push-pull rod 13 and the first axis is parallel to one side of the detection corner. When the push-pull rod 13 moves along the third direction to the position closest to the bolt 3, and the length direction of the push-pull rod 13 is parallel to the third direction in the detection posture, the detection block 6 is in the working position, and the detection corner and bolt 3 are engaged. The internal dimensions of the guide groove 14 in the first direction are all larger than the corresponding dimensions of the push-pull rod 13, thereby satisfying the requirement that the push-pull rod 13 can rotate around the first axis within the guide groove 14.

[0037] Preferably, the bolt 3 points to the inside of the bend of the wire harness bracket. The preset range of the included angle affects the position of the bolt 3 in the first direction. Within this preset range, the position range of the bolt 3 includes the position where it can be detected normally and the position where it interferes with the detection block 6. When the bolt 3 is in the position range where it interferes with the detection block 6, the push-pull rod 13 moves closer to the bolt 3 along the third direction to the end of its stroke, and then the bolt 3 blocks the push-pull rod 13 from entering the detection posture.

[0038] As a preferred embodiment, the guide groove 14 is provided with a fulcrum, a reference portion, and a thrust assembly 23 that cooperate with the push-pull rod 13. The fulcrum provides a first pivot, and the fulcrum and the thrust assembly 23 are arranged at different positions in the third direction. The reference portion is configured to abut against the push-pull rod 13 to allow the push-pull rod 13 to enter the detection posture. The push-pull rod 13 is provided with a thrust area that slides with the thrust assembly 23. A groove 15 is provided in the thrust area. The thrust area is configured such that during the process of the thrust assembly 23 passing through the thrust area... In this configuration, the push-pull rod 13 abuts against the reference part. The groove 15 is configured such that, during the process of the thrust assembly 23 passing through the groove 15, the internal corner is detected to be adjacent to the bolt 3. The push-pull rod 13 first moves away from the reference part and then abuts against it. Specifically, by arranging the fulcrum and the thrust assembly 23 at different positions along the third direction, an effective lever arm is formed between the force application position of the thrust assembly 23 on the push-pull rod 13 and the first rotating shaft. Furthermore, the force application position of the thrust assembly 23 on the push-pull rod 13 is set as far away from the first rotating shaft as possible to ensure that the lever arm length is sufficient. When the reference part and the thrust assembly 23 are set on the same side in the guide groove 14, the reference part and the thrust assembly 23 are distributed on both sides of the first rotating shaft along the third direction; when the reference part and the thrust assembly 23 are set on opposite sides in the guide groove 14, the reference part and the thrust assembly 23 are distributed on the same side of the first rotating shaft along the third direction.

[0039] Preferably, the thrust assembly 23 can be a rigid component or an elastic component, such as an elastic set screw or a spring-loaded protrusion. When the thrust assembly 23 is an elastic component, it maintains its relative distance with the reference part in the first direction through elastic force. The thrust assembly 23 has elastic force, which can better reduce the impact of the collision between the bolt 3 and the detection block 6.

[0040] Preferably, when the push-pull rod 13 is in the detection posture, the end of the thrust assembly 23 is just flush with the surface of the thrust area in the third direction downward; when the thrust assembly 23 corresponds to the groove 15 in the first direction, a gap is formed between the end of the thrust assembly 23 and the groove 15, which satisfies the requirement that the push-pull rod 13 rotates around the first axis, thereby causing the detection block 6 to move closer to or away from the bolt 3 at a position adjacent to the bolt 3, and when the thrust assembly 23 is in contact with the innermost side of the groove 15, the detection block 6 is furthest away from the bolt 3.

[0041] Preferably, during the movement of the push-pull rod 13, the end of the thrust assembly 23 remains in contact with the surface of the thrust area or groove 15. The contact method can be magnetic attraction, that is, one of the ends of the thrust assembly 23 or the surface of the thrust area or groove 15 is magnetic, and the other can be attracted by magnetism. This magnetic attraction method is suitable when the push-pull rod 13 is in a non-horizontal state. The contact method can also be gravity adaptive. When the third direction is horizontal, with the first rotating shaft as the center, the specific gravity of the end of the push-pull rod 13 connected to the detection block 6 is set to be greater. Then, under the action of gravity, the push-pull rod 13 can automatically keep the thrust assembly 23 in contact with the surface of the thrust area or groove 15.

[0042] Preferably, the groove 15 is located on the side of the thrust zone away from the bolt 3. When the push-pull rod 13 moves the detection block 6 to the working position along the third direction toward the bolt 3, the thrust assembly 23 just leaves the groove 15 and re-aligns with the surface outside the groove 15 in the thrust zone. During the process of the push-pull rod 13 moving toward the bolt 3, when the thrust assembly 23 passes the groove 15, the push-pull rod 13 rotates to drive the detection block 6 away from and then toward the bolt 3 along the first direction, and finally makes the bolt 3 cooperate with the detection corner, and the push-pull rod 13 is in the detection posture. When the bolt 3 interferes with the detection corner, the push-pull rod 13 cannot rotate to the detection posture. During the process of the push-pull rod 13 moving away from the bolt 3, when the thrust assembly 23 passes the groove 15, the push-pull rod 13 drives the detection block 6 away from and then toward the bolt 3 along the first direction, and finally makes the bolt 3 completely separate from the detection corner. At the same time, the push-pull rod 13 automatically returns to and remains in the detection posture.

[0043] In a preferred embodiment of the fulcrum, the fulcrum is a first protrusion 16, which is disposed on the inner wall of the guide groove 14. Specifically, the first protrusion 16 is disposed on the inner wall of the guide groove 14 along the first direction near the base 4, and the first protrusion 16 is distributed in a direction parallel to the first axis of rotation. The contact position between the first protrusion 16 and the push-pull rod 13 forms the first axis of rotation. When the contact position is an edge, the edge is the first axis of rotation, but the edge is prone to wear. When the contact position is a rounded corner, the axis of the rounded corner is the first axis of rotation. The first protrusion 16 can also be configured as a roller that contacts the push-pull rod 13, and the axis of the roller is the first axis of rotation, which can reduce the friction between the first protrusion 16 and the push-pull rod 13. In addition, other structures that can support the push-pull rod 13 and provide the formation of the first axis of rotation can be disposed on the inner wall of the guide groove 14 along the first direction near the base 4.

[0044] The above fulcrum adopts the first protrusion 16 scheme. There is also the need to limit the movement of the push-pull rod 13 in the third direction. In this regard, preferably, a handle is provided on the end of the push-pull rod 13 away from the detection block 6. The handle is used to operate the push-pull rod 13. At the same time, when the push-pull rod 13 moves to the working position, the handle is just limited and abuts against the outer wall of the guide seat 12.

[0045] In the preferred embodiment of the second embodiment of the fulcrum, the fulcrum is a sliding shaft 17 and a sliding groove 18 that are in sliding fit. One of the sliding shaft 17 and the sliding groove 18 is disposed on the push-pull rod 13, and the other is disposed on the inner wall of the guide groove 14. Specifically, the axial direction of the sliding shaft 17 is the first rotating shaft, and the sliding groove 18 extends along a third direction. The range of movement of the sliding groove 18 within the sliding groove 18 limits the range of movement of the push-pull rod 13 in the third direction, which facilitates the accurate movement of the detection block 6 to the working position. The end of the sliding shaft 17 is in movable fit with the sliding groove 18. Preferably, the end of the sliding shaft 17 can be provided with a roller so that the roller rolls into the sliding groove 18 to reduce friction. In actual installation, the sliding shaft 17 is disposed as far away from the thrust assembly 23 as possible along the third direction.

[0046] The above fulcrum adopts a scheme of sliding shaft 17 and sliding groove 18 to ensure the stability of the first rotating shaft, while optimizing the motion mode of push-pull rod 13. Furthermore, the sliding shaft 17 is limited to move within the sliding groove 18, and the range of motion of push-pull rod 13 in the third direction is also limited, which facilitates accurate positioning of detection block 6.

[0047] As a preferred technical solution of the above embodiments, the reference part is the second protrusion 19. The second protrusion 19 is disposed on the inner wall of the guide groove 14. Specifically, the second protrusion 19 is disposed on the inner wall of the guide groove 14 on the side away from the base 4 along the first direction. The second protrusion 19 is distributed in a direction parallel to the first rotation axis. When the length direction of the push-pull rod 13 is parallel to the third direction and has entered the detection posture, the push-pull rod 13 just abuts against the second protrusion 19.

[0048] In another embodiment of the present invention, a guide hole 20 is provided on the guide seat 12 along the first direction, and at least one positioning hole 21 adapted to the guide hole 20 is provided on the push-pull rod 13. The positioning hole 21 is configured such that when the detection corner and the bolt 3 are engaged and the push-pull rod 13 is in the detection posture, the guide hole 20 and the positioning hole 21 are coaxially corresponding and the same pin 22 is inserted. Otherwise, the pin 22 cannot be inserted into the positioning hole 21. Specifically, the inner diameter of the guide hole 20 and the inner diameter of the positioning hole 21 are both matched with the outer diameter of the pin 22. When the detection block 6 moves to the working position along the third direction, when the push-pull rod 13 abuts against the reference part, that is, when the push-pull rod 13 is in the detection posture, the bolt 3 and the detection inner corner are engaged, and the guide hole 20 and the positioning hole 21 are coaxially aligned, and the pin 22 can be fully inserted into the positioning hole 21; however, when the bolt 3 interferes with the detection inner corner, the push-pull rod 13 and the reference part cannot abut, and the guide hole 20 and the positioning hole 21 are misaligned, and the pin 22 cannot be inserted into the positioning hole 21; when the pin 22 cannot be inserted into the positioning hole 21, the bolt 3 does not meet the detection conditions and the detection must be stopped.

[0049] Preferably, the guide hole 20 and the positioning hole 21 are formed by the sleeve on the guide seat 12 and the sleeve on the push-pull rod 13, respectively, which can ensure the accuracy of the holes, and the sleeve is detachable, making it easy to replace after wear. Furthermore, another positioning hole 21 can be provided on the push-pull rod 13 to position the push-pull rod 13 at the position farthest from the bolt 3.

[0050] In another embodiment of the present invention, the clamp assembly includes a pressure arm 7, which is hinged to the base 4 along an axis perpendicular to the first direction, so that the pressure arm 7 can switch between a pressing state and a lifting state. A pressure block 8 is connected to the pressure arm 7 via an adjustment assembly. A reference block 9 that mates with the pressure block 8 is provided on the detection table 5. Specifically, the reference block 9 is arranged near the insertion hole of the positioning pin. Further, the reference block 9 may be provided with an insertion hole that mates with the positioning pin, thereby ensuring that the positioning reference and the fixing reference are adjacent or at the same reference point, minimizing the impact of the clamping force on the wire harness bracket. Preferably, the pressure block 8 and the reference block 9 clamp the first panel 1 of the wire harness bracket in a surface contact manner, thereby enabling the two sets of clamp assemblies to completely position and fix the wire harness bracket. The adjustment assembly is used to adjust the clamping distance when the pressure block 8 and the reference block 9 mate, and also to adjust the mating surface angle when the pressure block 8 and the reference block 9 mate, ensuring surface contact.

[0051] As a preferred technical solution of this embodiment, the adjustment component consists of two screws 10 arranged along the length of the pressure arm 7. The screws 10 are movably set relative to the pressure arm 7 within a preset stroke along the fourth direction. The fourth direction is perpendicular to the rotation axis of the pressure arm 7. The fourth direction is also configured such that when the pressure arm 7 is in the pressed state, the fourth direction is parallel to the first direction. Nuts 11 are provided at both ends of the screws 10 and are arranged on both sides of the pressure arm 7. Specifically, the pressure arm 7 is provided with two through holes or one waist-shaped hole along the fourth direction, through holes or waist-shaped hole for the screws 10 to move through. When the two nuts 11 on the same screw 10 are tightened, the movement of the screw 10 in the fourth direction can be limited. Preferably, a washer is provided on the side of the nut 11 near the pressure arm 7. In actual use, by adjusting the nuts 11 on the two screws 10 at the same time to adjust the position of the screw 10 in the fourth direction, the clamping distance when the pressure block 8 and the reference block 9 are engaged can be adjusted. By adjusting the nut 11 on any one of the screws 10 individually to finely adjust the position of the screw 10 in the fourth direction, the mating surface angle when the pressure block 8 and the reference block 9 are engaged can be adjusted.

[0052] 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.
