[0047] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0048] Before introducing the profile measurement tool provided by the embodiments of the present application, the related technologies of the present application are described.

[0049] It can be understood that the three-coordinate measuring device has the following defects in addition to the defect of limited space measurement.

[0050] The three-coordinate measuring device has low measurement efficiency. It takes about 1 hour from erecting the three-coordinate measuring device to the end of measurement, and it takes about 2 hours to move the product to the measurement room for measurement, which is time-consuming.

[0051] The three-coordinate measuring device is difficult to operate. The use of the three-coordinate measuring device requires professional technical personnel, and two people need to work together, which has high professional and technical requirements for operators.

[0052] The three-coordinate measuring device has high cost. A set of three-coordinate measuring device costs about 500,000 yuan and needs to be maintained, and professional operators also need to be equipped.

[0053] The three-coordinate measuring device has poor intuitiveness of measurement data. Since the measurement result of the three-coordinate measuring device can only be expressed in the form of measurement points, the measurement data is discontinuous, which increases the difficulty of data processing and analysis.

[0054] Based on the above situation, the present application provides a contour line measuring tool to solve the above problems.

[0055] Please refer to Figure 1 and Figure 2 , Figure 1 is a structure diagram of a contour line measuring tool 1 provided in an exemplary embodiment of the present disclosure, Figure 2 is a sectional view along A-A in Figure 1 The present application provides a contour line measuring tool 1. The contour line measuring tool 1 comprises an input member 12 and an output member 13. The input member 12 is configured to be in contact with the contour line of the measured member and to slide back and forth in the first direction in response to the change of the contour line. The output member 13 is in transmission connection with the input member 12, and the output member 13 is configured to be connected to a recording member 16 and reciprocate in the second direction in response to the sliding of the input member 12, so as to drive the recording member 16 to record the trace line corresponding to the contour line of the measured member.

[0056] The surface of the input member 12 configured to be in contact with the contour line of the measured member is a contact surface 122.

[0057] It can be understood that the first direction and the second direction are not parallel to each other.

[0058] It can be understood that the measured member can be a rolled edge product, such as a car door or a hood.

[0059] It can be understood that the recording member 16 can be a marker pen, a pen, a ballpoint pen, a pencil, etc. The embodiments of the present application do not limit this, as long as it can draw a trace on the part that needs to be drawn in the corresponding application environment.

[0060] As will be understood, during measurement, contact surface 122 is brought into contact with the contour of the object under test. When the contour of the object under test generates a thrust against input member 12, input member 12 moves in a first direction, transferring force to output member 13, causing output member 13 to move in a second direction. Correspondingly, the trace drawn by recording member 16 mounted on output member 13 moves in the second direction, away from input member 12.

[0061] When the thrust exerted by the contour of the measuring component on input member 12 decreases, input member 12 moves back in the first direction. This causes input member 12 to drive output member 13 back in the second direction. Correspondingly, the trace drawn by recording member 16 mounted on output member 13 moves back in the second direction.

[0062] Specifically, when the contour line measuring tool 1 provided in this embodiment is applied to measure the contour lines of the rolled edges of products such as car doors and hoods after the rolled edges are completed at the tire membrane 2 hemming station, the operation process can be performed according to the following.

[0063] S100, first install the recording element 16 on the output element 13;

[0064] S200, the contour line measuring tool 1 is placed on one side of the fetal membrane 2, and the mounting member 11 is in contact with the fetal membrane 2, a portion of the contact surface 122 is located outside the fetal membrane 2, and another portion of the contact surface 122 is in contact with the molding contour line of the fetal membrane 2 for molding the product hem, and the pen tip of the recording member 16 is in contact with the fetal membrane 2, as shown in FIG. Figure 3 As shown, Figure 3 A schematic diagram of the cooperation between the contour line measuring tool 1 and the fetal membrane 2 provided in an exemplary embodiment of the present disclosure;

[0065] S300, moving the contour line measuring tool 1 along the molding contour line so that the recording member 16 leaves a first imprint line on the fetal membrane 2, the first imprint line being the reference line;

[0066] S400, mounting the product to be rolled on the tire membrane 2 and performing a rolling operation;

[0067] S500, after the product is rolled on the membrane 2, the contour line measuring tool 1 is placed on one side of the membrane 2, and the mounting part 11 is in contact with the membrane 2, a part of the contact surface 122 is located outside the membrane 2 and in contact with the product's rolling contour line, and another part of the contact surface 122 is in contact with the molding contour line, and the pen tip of the recording part 16 is in contact with the membrane 2, as shown in FIG. Figure 4 As shown, Figure 4 A schematic diagram of the cooperation between the contour line measuring tool 1 and the hemming part of the product provided in an exemplary embodiment of the present disclosure;

[0068] S600, move the profile line measuring tool 1 along the forming profile line so that the recording member 16 leaves a second trace line on the tire membrane 2, the second trace line being the edging track line.

[0069] It can be understood that when the edging profile line of the product exceeds the forming profile line of the tire membrane 2 and the edging profile line of the product pushes the input member 12, the input member 12 moves in the first direction to drive the output member 13 to move so that the output member 13 moves in the second direction. Correspondingly, the recording member 16 installed on the output member 13 draws a second trace line in the second direction.

[0070] S700, judge whether the interval between the first trace line and the second trace line meets the requirements, if yes, determine that the edging quality of the product meets the requirements; if not, optimize the tire membrane 2 so that the interval between the first trace line and the second trace line meets the requirements.

[0071] It can be understood that when the edging profile line of the product is consistent with the forming profile line of the tire membrane 2, the first trace line and the second trace line should coincide.

[0072] In the embodiment, the profile line measuring tool 1 is used to measure the edging profile line of the product, so that the required measurement space is small. In this way, not only the convenience of measuring the edging profile line of the product can be improved, but also interference with other components during measurement at the tire membrane 2 station can be avoided, thereby the applicable scenarios can be expanded.

[0073] Meanwhile, the profile line measuring tool 1 provided by the embodiment has a simple structure. This not only improves the operability of measuring the edging profile line of the product, so that the measurement efficiency is improved, but also reduces the operation difficulty, thereby the professional requirement of measurement can be reduced.

[0074] Moreover, the profile line measuring tool 1 provided by the embodiment has a simple structure and can not need to be configured with a special storage space. This not only makes the tool easy to manufacture and helps to reduce the manufacturing cost, but also improves the maintenance convenience, thereby the maintenance cost can be reduced.

[0075] In addition, compared with a three-coordinate measuring device, the profile line measuring tool 1 provided by the embodiment not only has a low failure rate, but also has a good visualization of the measurement result, which can directly show the deviation between the edging profile line of the product and the forming profile line of the tire membrane 2, thereby helping to quickly optimize the edging track.

[0076] Furthermore, the profile line measuring tool 1 provided by the embodiment has a small structure, which is convenient to carry and can be easily transferred between many occasions.

[0077] Please refer to Figure 1In some embodiments, the profile measurement tool 1 further comprises a mounting member 11 and an elastic member 14. The input member 12 is slidingly arranged on the mounting member 11 along a first direction. One end of the input member 12 is provided with a wedge surface 121, and the other end is configured to contact the profile of the measured member. The output member 13 is slidingly arranged on the mounting member 11 along a second direction. One end of the output member 13 is in contact with the wedge surface 121, and the other end is configured to be connected with a recording member 16. The two ends of the elastic member 14 are connected with the mounting member 11 and the output member 13 respectively. The back-and-forth sliding of the input member 12 along the first direction is transmitted to the output member 13 through the wedge surface 121, so as to make the output member 13 reciprocate along the second direction.

[0078] It can be understood that the other end of the input member 12 is provided with a contact surface 122 configured to contact the profile of the measured member.

[0079] It can be understood that, during the measurement, the contact surface 122 is in contact with the profile of the measured member. When the profile of the measured member generates a pushing force on the input member 12, the input member 12 moves towards the output member 13 along the first direction. The wedge surface 121 pushes the output member 13, so as to make the output member 13 move away from the input member 12 along the second direction. At this time, the elastic member 14 is compressed and shortened due to the movement of the output member 13. Correspondingly, the trace drawn by the recording member 16 installed on the output member 13 moves away from the input member 12 along the second direction.

[0080] When the pushing force generated by the profile of the measured member on the input member 12 decreases, the input member 12 moves away from the output member 13 along the first direction. At this time, the pushing force of the wedge surface 121 on the output member 13 decreases, so that the elastic member 14 is lengthened due to the restoring force. Under the action of the restoring force of the elastic member 14, the output member 13 moves back along the second direction. Correspondingly, the trace drawn by the recording member 16 installed on the output member 13 moves back along the second direction.

[0081] It can be understood that, when the profile of the rolled edge of the product exceeds the forming profile of the tire membrane 2, the profile of the rolled edge of the product generates a pushing force on the input member 12. The input member 12 moves towards the output member 13 along the first direction. The wedge surface 121 pushes the output member 13, so as to make the output member 13 move away from the input member 12 along the second direction. At this time, the elastic member 14 is compressed and shortened due to the movement of the output member 13. Correspondingly, the trace drawn by the recording member 16 installed on the output member 13 draws a second trace line along the second direction away from the input member 12.

[0082] In the embodiment, the above scheme makes the transmission mode between the input member 12 and the output member 13 simple and easy to form, so as to make the overall structure of the profile measurement tool 1 simple.

[0083] Referring to Figure 5 , Figure 5 is an exploded view of the mount 11 provided in the exemplary embodiment of the present disclosure. In some embodiments, the mount 11 comprises a base 111 and a fixing seat 112 connected together. The input member 12 is slidingly arranged on the base 111 in a first direction. The wedge surface 121 is located on one side of the base 111 close to the fixing seat 112. The end of the input member 12 away from the wedge surface 121 is located on the side of the base 111 away from the fixing seat 112, i.e., the contact surface 122 is located on the side of the base 111 away from the fixing seat 112. The output member 13 is slidingly mounted on the fixing seat 112 in a second direction.

[0084] It can be understood that the base 111 and the fixing seat 112 can be detachably connected; or the base 111 and the fixing seat 112 can be welded or glued together after being matched with the input member 12 and the output member 13, respectively.

[0085] In the present embodiment, by the above arrangement, the base 111 and the fixing seat 112 can be respectively formed, so that the difficulty of forming the mount 11 into a structure matched with the input member 12 and the output member 13 can be reduced, and thus the manufacturing cost can be reduced.

[0086] Referring to Figure 2 In some embodiments, the base 111 is provided with a first through hole 1111. The input member 12 is arranged through the first through hole 1111. The axis of the first through hole 1111 is parallel to the first direction. In this way, the structure matched between the input member 12 and the base 111 is simple, the assembly of the input member 12 and the base 111 is easy, and the processing difficulty of the base 111 can be reduced.

[0087] In another embodiment, the input member 12 can be slidingly arranged on the base 111 through a slot block structure. Specifically, one of the input member 12 and the base 111 is provided with a sliding groove, and the other is provided with a sliding block matched with the sliding groove. The slot width of the sliding groove is less than the groove bottom width, so that the sliding block is abutted and matched with the sliding wall of the sliding groove in a direction perpendicular to the groove bottom.

[0088] Referring to Figure 2 In some embodiments, the fixing seat 112 is provided with a second through hole 1121. The output member 13 is arranged through the second through hole 1121. The axis of the second through hole 1121 is parallel to the second direction. In this way, the structure matched between the output member 13 and the fixing seat 112 is simple, the assembly of the output member 13 and the fixing seat 112 is easy, and the processing difficulty of the fixing seat 112 can be reduced.

[0089] In another embodiment, the output member 13 can be slidingly arranged on the fixing seat 112 through a slot block structure. Specifically, one of the output member 13 and the fixing seat 112 is provided with a sliding slot, and the other is provided with a sliding block matched with the sliding slot. The slot width of the sliding slot is less than the slot bottom width, so that the slot wall of the sliding slot and the sliding block are matched in the direction perpendicular to the slot bottom.

[0090] Referring to Figure 2 In some embodiments, the fixing seat 112 is provided with a mounting hole 1122, and the elastic member 14 is arranged in the mounting hole 1122. In this way, the compression deformation of the elastic member 14 can be limited by the hole wall of the mounting hole 1122, so as to improve the consistency of the direction of the compression deformation of the elastic member 14.

[0091] Referring to Figure 2 In some embodiments, the fixing seat 112 is provided with an opening 1123 on the side facing the base 111. The opening 1123 is arranged adjacent to the input member 12. The opening 1123 is in communication with the mounting hole 1122. In this way, the input member 12 can slide in the opening 1123, so as to reduce the length of the input member 12 in the second direction, thereby improving the structural compactness of the profile measurement tool 1.

[0092] Referring to Figure 1 Or Figure 5 In some embodiments, the mounting member 11 further comprises a bolt 113 and a positioning pin 114. The rod end of the bolt 113 is threadedly connected to one of the base 111 and the fixing seat 112 after penetrating through the other. The two ends of the positioning pin 114 are respectively in interference fit with the base 111 and the fixing seat 112. In this way, the fixing seat 112 and the base 111 can be detachably connected, which is beneficial to assembly and maintenance, and the relative position between the fixing seat 112 and the base 111 can be improved in accuracy by the positioning pin 114, so as to avoid the position deviation between the fixing seat 112 and the base 111 caused by the connection of the bolt 113.

[0093] Referring to Figure 1 Or Figure 5 In some embodiments, the outer wall of the fixing seat 112 is provided with an ear plate 115. The ear plate 115 is arranged adjacent to the base 111. The ear plate 115 is provided with a bolt through hole. The rod end of the bolt 113 is threadedly connected to the base 111 after penetrating through the bolt through hole. The two ends of the positioning pin 114 are respectively in interference fit with the ear plate 115 and the base 111. In this way, the height dimension of the part where the fixing seat 112 cooperates with the bolt 113 and the positioning pin 114 can be reduced, so as to reduce the gravity of the profile measurement tool 1, thereby improving the ease of operation of the profile measurement.

[0094] Referring to Figure 6 , Figure 6is a structural schematic view of the base 111 provided in the exemplary embodiments of the present disclosure. In some embodiments, the side of the base 111 away from the fixing base 112 is provided with a plurality of contact strips 116. The cross section of the contact strip 116 is semicircular, and the planar side wall of the contact strip 116 is connected with the base 111. In this way, the line-plane contact is formed between the base 111 and the tire membrane 2, so that the flatness requirement of the contact part between the base 111 and the tire membrane 2 can be reduced, and the manufacturing difficulty of the production can be reduced.

[0095] Exemplarily, the side of the base 111 away from the fixing base 112 is provided with two contact strips 116.

[0096] Please refer to Figure 7 , Figure 7 is a structural schematic view of the input member 12 provided in the exemplary embodiments of the present disclosure. In some embodiments, the input member 12 comprises a first block 123 and a second block 124 connected with each other. In the first direction, the first block 123 is in sliding fit with the mounting member 11. The surface of the first block 123 away from the second block 124 is a contact surface 122. The contact surface 122 is configured to contact with the profile line of the measured member. The side of the second block 124 away from the first block 123 is provided with a wedge surface 121. In this way, the structure of the input member 12 is simple, and the input member 12 is easy to manufacture.

[0097] It can be understood that the inclination angle of the wedge surface 121 relative to the second direction can be changed to change the proportional relationship between the interval between the first trace line and the second trace line drawn by the recording member 16 and the profile line of the roller and the profile line of the forming roller.

[0098] It can be understood that the length dimension of the inclined surface in the second direction and the length dimension of the input member 12 in the first direction (specifically the length dimension of the first block 123 in the first direction) can be changed, so that the range of the profile line measuring device can be changed.

[0099] Please refer to Figure 7 In some embodiments, in the cross section perpendicular to the first direction, the cross section shape of the first block 123 is non-circular. In this way, the rotation of the input member 12 can be avoided, so that the reciprocating motion of the input member 12 in the first direction during the measurement can be improved, and the accuracy of the measurement can be improved.

[0100] Optionally, the cross section shape of the first block 123 is rectangular.

[0101] Please refer to Figure 8 , Figure 8is a structural schematic view of the output piece 13 provided in the example embodiment of the present disclosure. In some embodiments, the output piece 13 comprises a contact block 131 and a guide rod 132 connected together. In the second direction, the guide rod 132 is in sliding fit with the mounting piece 11. One end of the contact block 131 is connected with the sidewall of the guide rod 132, and the other end is in contact with the wedge surface 121. In this way, the output piece 13 is simple in structure and easy to manufacture.

[0102] Referring to Figure 8 In some embodiments, the contact block 131 is in a semi-cylindrical structure, the planar sidewall of the contact block 131 is connected with the guide rod 132, and the curved sidewall of the contact block 131 is in contact with the wedge surface 121. In this way, the contact block 131 is in line contact with the wedge surface 121, so that the accuracy requirement of the part where the contact block 131 is in contact with the wedge surface 121 can be reduced, and thus the manufacturing difficulty of the contact block 131 can be reduced.

[0103] Referring to Figure 8 In some embodiments, the guide rod 132 comprises a fit segment 1321 and a connecting segment 1322 connected together. In the second direction, the fit segment 1321 is in sliding fit with the mounting piece 11. The sidewall of the connecting segment 1322 is connected with the contact block 131. The end face of the connecting segment 1322 towards the fit segment 1321 is connected with the elastic piece 14. In this way, the guide rod 132 can be in abutment with the elastic piece 14 through the end face of the fit segment 1321, so that the operability of the fit between the guide rod 132 and the elastic piece 14 can be improved.

[0104] Referring to Figure 1 In some embodiments, the profile measurement tool 1 further comprises a pen sleeve 15. The pen sleeve 15 is connected with the end of the output piece 13 away from the wedge surface 121. The pen sleeve 15 is configured to mount a recording piece 16. In this way, the operability of the connection between the profile measurement tool 1 and the recording piece 16 can be improved.

[0105] It can be understood that the axis of the pen sleeve 15 is parallel to the first direction. The axis of the mounted recording piece 16 is parallel to the first direction.

[0106] Specifically, a screw is mounted on the pen sleeve 15. The rod end of the screw can be in abutment with the outer surface of the recording piece 16. In this way, the recording piece 16 that can be penetrated through the pen sleeve 15 can be fixed.

[0107] In some embodiments, the pen sleeve 15 is in abutment with the mounting piece 11, and the pen sleeve 15 is threadedly connected with the output piece 13. In this way, the initial position of the output piece 13 on the wedge surface 121 can be adjusted through the length of the thread connection between the pen sleeve 15 and the output piece 13.

[0108] Specifically, a threaded hole is provided on the pen sleeve 15, and one end of the fit segment 1321 is inserted into the threaded hole and is threadedly connected with the threaded hole.

[0109] Referring to Figure 9 , Figure 9 is a schematic view of the relationship between the wedge surface 121 and the second direction in the exemplary embodiment of the present disclosure. In some embodiments, the included angle between the second direction and the wedge surface 121 is α, which satisfies: α≤45°.

[0110] It can be understood that the movement size of the input member 12 in the first direction is H, and the corresponding movement size L of the output member 13 in the second direction is Hcotα. When α is less than or equal to 45°, the corresponding cotα is greater than or equal to 1. At this time, the spacing between the first trace line and the second trace line can be made to be at least not less than the deviation between the hemming contour line and the forming contour line. In this way, the operator can quickly judge whether the quality of the rolled edge of the product meets the requirements.

[0111] In some embodiments, the first direction and the second direction are perpendicular to each other, and the value of cotα is an integer. In this way, the operator can quickly determine the deviation between the rolled edge contour line of the product and the forming contour line of the tire membrane 2 according to the spacing between the first trace line and the second trace line.

[0112] Exemplarily, cotα=1, and the corresponding α is 11.31°.

[0113] Exemplarily, when the spacing between the first trace line and the second trace line is 1.5 mm, the deviation between the rolled edge contour line of the product and the forming contour line of the tire membrane 2 is 0.3 mm.

[0114] Referring to Figure 2 In some embodiments, the elastic member 14 is a helical cylindrical compression spring, and the elastic member 14 is sleeved on the output member 13. In this way, a stable elastic force can be provided by the helical cylindrical compression spring, so that the output member 13 cooperating therewith can stably operate under the expected elastic force.

[0115] Specifically, the elastic member 14 is sleeved and cooperates with the cooperating section 1321. The two ends of the elastic member 14 respectively abut against the connecting section 1322 and the hole bottom of the mounting hole 1122.

[0116] In some embodiments, the first direction and the second direction are perpendicular to each other. In this way, based on the simple trigonometric function theorem, the difficulty of calculating the deviation between the rolled edge contour line of the product and the forming contour line of the tire membrane 2 can be quickly converted according to the spacing between the first trace line and the second trace line, thereby reducing the calculation difficulty.
