Description

Technical Field

[0001] This application relates to the field of tooling technology for vehicle production, and in particular to an external water-cutting press-fit inspection tooling and a press-fit inspection method. Background Technology

[0002] In vehicles, an external windshield washer typically refers to a sealing device installed on the outside of the door to prevent rainwater from entering the vehicle and to keep the windows clean. Structurally, an external windshield was generally assembled from a sealing strip and a metal trim strip.

[0003] In the production of external water deflectors, it is generally necessary to perform contour inspection after the external water deflector is assembled. Currently, it is usually done by first using a press-fitting fixture with rollers to fix the sealing strip to the fixture plate, then pressing the bright strip onto the sealing strip, and then transferring the assembled external water deflector to the contour inspection fixture. The inspection fixture simulates the positioning reference in the real vehicle environment to fix the position of the bright strip snap-fit ​​lip in the external water deflector, and then using a dial indicator installed on the inspection fixture to perform contour inspection.

[0004] Because pressing and inspection fixtures need to be used separately, the existing external water cutter production process requires more steps and personnel, and the investment in tooling equipment is also large, which is not conducive to reducing the production cost of external water cutters. Summary of the Invention

[0005] In view of this, this application aims to provide an external water cutter press-fit inspection fixture to help reduce the production cost of external water cutters.

[0006] To achieve the above objectives, the technical solution of this application is implemented as follows: An external water-cutting press-fit inspection fixture includes a machine base, and a sheet metal simulation block, a positioning reference block, and a contour inspection component disposed on the machine base; The sheet metal simulation block is used to support the external water cutter to be pressed and inspected, and the sheet metal simulation block has a contoured end that is inserted into the mounting groove on the external water cutter. The positioning reference block is driven to slide relative to the sheet metal simulation block, and the positioning reference block can slide to a first state that supports the bright strip snap-fit ​​lip on the outer water cutter, or to a second state that removes the support for the bright strip snap-fit ​​lip. The profile inspection component includes an inspection arm with an installation point for mounting a profile gauge. When the positioning reference block is in the first state, the inspection arm can enter the inspection position and perform profile inspection on the external water cutter using the mounted profile gauge.

[0007] Furthermore, a guiding mechanism and / or a locking mechanism are provided between the positioning reference block and the sheet metal simulation block; The guiding mechanism is adapted to guide the sliding of the positioning reference block relative to the sheet metal simulation block; The locking mechanism is adapted to lock and fix the positioning reference block onto the sheet metal simulation block in the first state.

[0008] Furthermore, the guiding mechanism includes a guide pin disposed on the sheet metal simulation block and a guide hole disposed on the positioning reference block; The guide hole is an elongated hole arranged along the sliding direction of the positioning reference block, and the guide pin passes through the guide hole.

[0009] Furthermore, the locking mechanism includes a locking hole on the sheet metal simulation block, a connecting hole on the positioning reference block, and a locking pin in the connecting hole; In the first state, the connecting hole can be aligned with the locking hole, and the locking pin can be connected to the locking hole to lock the positioning reference block onto the sheet metal simulation block.

[0010] Furthermore, the sheet metal simulation block includes a first simulation block fixedly mounted on the machine base, and a second simulation block driven to slide relative to the machine base; The positioning reference block is slidably disposed relative to the first simulation block, and the second simulation block is driven to allow its contoured end to insert into or disengage from the mounting slot.

[0011] Furthermore, there are multiple first simulation blocks and multiple second simulation blocks, and the multiple first simulation blocks and multiple second simulation blocks are alternately arranged along the length direction of the external water shear; and / or, The machine platform is provided with a first driving unit connected to the second simulation block, and the first driving unit is used to drive the second simulation block to slide.

[0012] Furthermore, the machine base is provided with a second driving unit connected to the positioning reference block, the second driving unit being used to drive the positioning reference block to slide; A limiting block is provided on the side of the positioning reference block that is connected to the second driving part. When the second driving part drives the positioning reference block to slide to the first state, the limiting block abuts against the first simulation block for limitation.

[0013] Furthermore, the machine base is provided with a lifting drive unit and a support block that is driven to lift by the lifting drive unit; The support block is located below the outer water cutter to be press-fitted and inspected, and when the support block is driven to rise, it can support the bottom of the outer water cutter.

[0014] Furthermore, the inspection arm is rotatably mounted on the machine base, and the inspection arm is equipped with a sensing component; As the inspection arm is rotated, the mounting point can be positioned above the external water cutter to mount the profile gauge for profile inspection. The sensing component is adapted to detect whether the positioning reference block is in the first state when the inspection arm is flipped over above the external water cutter.

[0015] Compared with related technologies, this application has the following advantages: The external water cutter press-fit inspection fixture described in this application simultaneously sets up a sheet metal simulation block, a positioning reference block, and a contour inspection component. The sheet metal simulation block is inserted into the mounting groove on the external water cutter through its contouring end, which can support the external water cutter to be press-fitted and inspected, thus realizing the press-fitting of the external water cutter. After the external water cutter is press-fitted, the positioning reference block slides to the first state to support the bright strip snap-fit ​​lip on the external water cutter. By moving the inspection arm in the contour inspection component into the inspection position, the contour of the external water cutter can be inspected by the installed contour gauge. In this way, the press-fitting and contour inspection of the external water cutter can be realized in sequence using the same fixture. This not only reduces the number of processes and personnel required in the production of external water cutters, but also reduces the investment in tooling equipment required for the production of external water cutters, thereby helping to reduce the production cost of external water cutters.

[0016] In addition, a guiding mechanism and a locking mechanism are set between the positioning reference block and the sheet metal simulation block. On the one hand, the guiding mechanism can guide the sliding of the positioning reference block relative to the sheet metal simulation block, which helps to ensure the stability of the sliding process of the positioning reference block. On the other hand, the locking mechanism can lock the position of the positioning reference block when it slides to the first state, which helps to provide stable support for the bright strip snap-fit ​​lip on the outer water cutter, and can ensure the effectiveness of the contour inspection.

[0017] Secondly, the sheet metal simulation block includes a fixed first simulation block and a sliding second simulation block, and the positioning reference block is set to correspond to the first simulation block. At the same time, the second simulation block is driven to be able to detach from the mounting groove of the outer water cutter. On the one hand, the fixed setting of the first simulation block can be used to ensure the stability of the positioning reference block setting, so as to ensure the effectiveness of the contour inspection. On the other hand, the sliding setting of the second simulation block can be used to allow the second simulation block to detach from the mounting groove first after pressing and inspection, so as to facilitate the removal of the outer water cutter from the sheet metal simulation block.

[0018] Furthermore, by setting up a support block that is driven to rise and fall by a lifting drive unit, and ensuring that the support block can support the bottom of the outer water cutter when it is driven to rise, the support block can support the outer water cutter while the sheet metal simulation block bears the load. This ensures the support strength of the outer water cutter during press-fitting, avoids problems such as the outer water cutter sinking, which would affect the press-fitting effect of the outer water cutter, and avoids unnecessary interference to the subsequent contour inspection caused by the sinking of the outer water cutter.

[0019] In addition, a sensing component is installed on the inspection arm of the contour inspection component, and the sensing component can detect whether the positioning reference block is in the first state when the inspection arm is flipped above the outer water shear. During contour inspection, the position of the positioning reference block can be detected, and corresponding prompts can be given based on the position detection to ensure that the position of the positioning reference block meets the contour inspection requirements, thereby helping to ensure the reliability of contour inspection.

[0020] This application also proposes a method for inspecting the pressure fitting of external water cutters, the method comprising: The sealing strip of the external water cutter to be pressed and inspected is placed on the sheet metal simulation block, so that the contour end on the sheet metal simulation block is inserted into the snap-fit ​​groove on the sealing strip, and the bright strip is pre-installed on the sealing strip. The bright strip pre-installed on the sealing strip is pressed into place, thus assembling the bright strip and the sealing strip together. Drive the positioning reference block to slide relative to the sheet metal simulation block, and make the positioning reference block slide to a first state that supports the bright strip snap-fit ​​lip on the sealing strip; The inspection arm in the contour inspection assembly is moved into the inspection position, and the contour inspection of the assembled external water cutter is performed by the contour inspection tool installed on the inspection arm.

[0021] The external water cutter press-fit inspection method described in this application can realize the press-fitting and contour inspection of the external water cutter using the same tooling. This not only reduces the number of processes and personnel required in the external water cutter production process, but also reduces the investment in tooling equipment required for external water cutter production, thereby helping to reduce the production cost of external water cutters.

In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0027] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0028] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0029] This application provides an external water cutter press-fit inspection fixture (hereinafter referred to as "fixture"), which is used to assist in the press-fit assembly and contour inspection of the external water cutter 100 on the vehicle door. Furthermore, through its innovative structural design, the external water cutter press-fit inspection fixture of this embodiment can achieve the integrated design of the external water cutter 100 press-fit and contour inspection fixture, which helps to reduce the production cost of the external water cutter 100.

[0030] In related technologies, during the production of the outer water cutter 100 on a car door, due to limitations such as the product positioning of the outer water cutter 100, the tooling requirements for press-fit assembly and contour inspection of the outer water cutter 100 are inconsistent. The press-fit tooling needs to avoid the position of the bright strip snap-fit ​​lip 104 on the outer water cutter 100, while the inspection tooling needs to be able to simulate the outer sheet metal of a real car door as a positioning reference for the position of the bright strip snap-fit ​​lip 104 on the outer water cutter 100, thereby achieving the fixation of the bright strip snap-fit ​​lip 104.

[0031] The conflict between the above-mentioned requirements for the pressing fixture and contour inspection fixture for the outer water deflector 100 leads to the following process in the current production of the outer water deflector 100: First, the pressing fixture is used to fix the sealing strip 101 of the outer water deflector 100 onto the fixture plate, and then the bright strip 102 is pressed onto the sealing strip 101 using rollers. Then, the assembled outer water deflector 100 is transferred to the contour inspection fixture. The inspection fixture simulates the positioning reference in the real vehicle environment to fix the position of the bright strip snap-fit ​​lip 104 in the outer water deflector 100, and then a dial indicator installed on the inspection fixture is used to inspect the contour.

[0032] Therefore, since the production of the external water cutter 100 requires the separate use of pressing and inspection fixtures, the existing external water cutter 100 production process requires a large number of procedures and personnel, and the investment in tooling equipment is also large, which is not conducive to reducing the production cost of the external water cutter 100.

[0033] In view of this, in order to overcome the shortcomings of related technologies, the tooling in this embodiment combines... Figures 1 to 18 As shown, the overall design includes a machine base 1, a sheet metal simulation block 2, a positioning reference block 3, and a contour inspection component 4, all mounted on the machine base 1.

[0034] The sheet metal simulation block 2 is used to support the outer water cutter 100 to be pressed and inspected, and the sheet metal simulation block 2 has a contoured end 2a that is inserted into the mounting groove 103 on the outer water cutter 100.

[0035] The positioning reference block 3 is driven to slide relative to the sheet metal simulation block 2, and the positioning reference block 3 can slide to a first state where it is supported by the bright strip snap-fit ​​lip 104 on the external water cutter 100, or it can slide to a second state where the support for the bright strip snap-fit ​​lip 104 is removed.

[0036] The profile inspection component 4 includes an inspection arm 41, which is provided with an installation point 42 for installing a profile gauge. When the positioning reference block 3 is in the first state, the inspection arm 41 can enter the inspection position and can also perform profile inspection on the external water cutter 100 through the installed profile gauge.

[0037] Therefore, with the above configuration, by simultaneously setting the sheet metal simulation block 2, the positioning reference block 3, and the contour inspection component 4 on the machine tool 1, the sheet metal simulation block 3 can be inserted into the mounting groove 103 on the outer water cutter 100 through its contouring end 2a, which can support the outer water cutter 100 to be pressed and inspected, thus realizing the pressing of the outer water cutter 100. At the same time, after the outer water cutter 100 is pressed, the positioning reference block 3 slides to the first state of supporting the bright strip snap-fit ​​lip 104 on the outer water cutter 100. By making the inspection arm 41 in the contour inspection component 4 enter the inspection position, the contour inspection of the outer water cutter 100 can be performed by the installed contour inspection tool. In this embodiment, the pressing and contour inspection of the outer water cutter 100 can be realized in sequence using the same tooling. This not only reduces the number of processes and personnel required in the production process of the outer water cutter 100, but also reduces the investment in tooling equipment required for the production of the outer water cutter 100, thereby achieving the effect of reducing the production cost of the outer water cutter 100.

[0038] Based on the above overview, specifically, it is worth noting that machine tool 1, as the basis for setting up the sheet metal simulation block 2, positioning reference block 3, and contour detection component 4 in this embodiment, still refers to... Figure 3 As shown, in specific implementation, the machine tool 1 can be made of a rectangular metal plate (such as a steel plate). At the same time, in order to realize the arrangement of the tooling in the production site, it is understood that support legs can be set at the bottom of the machine tool 1 to support the machine tool 1 at a suitable height, or the machine tool 1 can be mounted and fixed on the frame or other basic structure of other equipment, so that the machine tool 1 can be at a suitable height, which is conducive to the pressing and contour inspection of the outer water cutter 100.

[0039] In addition, it is worth noting that, as the name suggests, the sheet metal simulation block 2 in this embodiment is used to simulate the part on the car door sheet metal used to install the outer water cutter 100. Therefore, in the design, the contour end 2a on the sheet metal module block 2 can be set to mimic the structure of the outer water cutter installation position on the car door sheet metal.

[0040] At the same time, continue to be Figures 1 to 7As shown, in some exemplary embodiments of this embodiment, preferably, the sheet metal simulation block 2 may include, for example, a first simulation block 21 fixedly mounted on the machine base, and a second simulation block 22 driven to slide relative to the machine base.

[0041] The aforementioned positioning reference block 3 is slidably set relative to the first simulation block 21, and the second simulation block 22 is driven so that its contour end 2a can be inserted into or removed from the mounting groove 103 on the outer water cutter 100.

[0042] It is understandable that by making the sheet metal simulation block 2 include a fixed first simulation block 21 and a sliding second simulation block 22, and making the positioning reference block 3 correspond to the first simulation block 21, while also making the second simulation block 22 drive to be released from the mounting groove 103 on the outer water cutter 100, on the one hand, this embodiment can utilize the fixed setting of the first simulation block 21 to ensure the stability of the positioning reference block 3 setting, so as to help ensure the effectiveness of the contour inspection.

[0043] On the other hand, by utilizing the sliding arrangement of the second simulation block 22, this embodiment can obviously allow the second simulation block 22 to be removed from the mounting slot 103 after the external water cutter 100 is press-fitted and inspected, and then the external water cutter 100 can be removed from the first simulation block 21. This makes it easier to disassemble the external water cutter 100 from the sheet metal simulation block 3, thereby improving the convenience of the production operation of the external water cutter 100.

[0044] In specific implementation, given that the sheet metal simulation block 2 simultaneously includes a fixed first simulation block 21 and a slidable second simulation block 22, in some exemplary embodiments of this embodiment, it is preferred that there are multiple first simulation blocks 21 and multiple second simulation blocks 22, and that the multiple first simulation blocks 21 and multiple second simulation blocks 22 are alternately arranged along the length direction of the outer water cut 100.

[0045] In this way, by using multiple first simulation blocks 21 and multiple second simulation blocks 22 alternately arranged along the length direction of the outer water cutter 100, it is obviously beneficial for each second simulation block 22 to be removed from the mounting groove 103 on the outer water cutter 100, and for the outer water cutter 100 to be pulled off from each first simulation block 21, thereby improving the convenience of disassembling the outer water cutter 100.

[0046] Furthermore, since there are multiple first simulation blocks 21 in the sheet metal simulation block 2, in this embodiment, there are also multiple reference positioning blocks 3 that are slidably arranged relative to the first simulation blocks 21, and each reference positioning block 3 is arranged in a one-to-one correspondence with each first simulation block 21. Meanwhile, the aforementioned contour detection component 4 is also as described above... Figure 1The setup shown has multiple components, and each contour detection component 4 is set at each reference positioning block 3 in a corresponding manner to inspect the contour of the outer water cut 100 at the position of each reference positioning block 3.

[0047] In this embodiment, please refer to Figure 3 As shown, based on the sheet metal simulation blocks 2 being multiple ones arranged sequentially along the length direction of the outer water cut 100, and the first simulation block 21 being fixedly set, in order to achieve the fixed setting of the first simulation block 21 on the machine tool 1, for example, a fixing seat 11 can be set on the machine tool 1. The fixing seat 11 is multiple ones matching the number and position distribution of the first simulation blocks, and each first simulation block 21 can be fixed on the corresponding fixing seat 11.

[0048] In addition to the aforementioned fixed seats 11, in some exemplary embodiments, such as this embodiment, support seats 12 may also be provided for each second simulation block 22. Each support seat 12 is fixed to the machine base 1, and the top of each support seat 12 can slide and abut against the bottom of the corresponding second simulation block 22. This not only guides and supports the sliding of the second simulation block 12, but also limits the movement of the second simulation block 22 when it is placed on the machine base 1, helping to ensure that the height of the second simulation block 22 meets the design requirements.

[0049] In this embodiment, in addition to the above-mentioned multiple fixed seats 11 and multiple support seats 12, in some exemplary embodiments, a limiting seat 13 may also be further provided.

[0050] Taking the external water cutter 100 on the machine 1 as an example, there are two limiting seats 13, which are respectively set at both ends of the external water cutter 100. The space for accommodating the external water cutter 100 is defined between the two limiting seats 13. And through the limiting seats 13 at both ends, this embodiment can obviously prevent the external water cutter 100 from shifting during press-fitting, which helps to ensure the accuracy of the relative position between the bright strip 102 and the sealing strip 101 in the external water cutter 100.

[0051] Continue as Figure 6 , Figure 7 as well as Figure 11 As shown, in some exemplary embodiments of this embodiment, the machine tool 1 is also provided with a first drive unit 23 connected to the second simulation block 22, which is used to drive the second simulation block 22 to slide.

[0052] In specific implementation, there are multiple second simulation blocks 22 based on this embodiment. Preferably, for example, there may also be multiple first driving units 23, and each first driving unit 23 is arranged in a one-to-one correspondence with each second simulation block 22.

[0053] Furthermore, as a feasible example, the first drive unit 23 can be a cylinder fixedly mounted on the machine tool 1, and each second simulation block 22 can be connected to the cylinder rod of the cylinder by screwing or other suitable conventional fastening methods.

[0054] It is worth noting that, in addition to having multiple first drive units 23, in some other embodiments, only one first drive unit 23 is set, and a related linkage structure is further set so that the same first drive unit 23 can be used to synchronously drive each second analog block 22 under the drive of the linkage structure.

[0055] In this embodiment, the following continues... Figure 1 , Figure 7 and combined Figure 8 , Figure 9 As shown, in some exemplary embodiments, the machine tool 1 is also provided with a second drive unit 31 connected to the positioning reference block 3, and the second drive unit 31 is used to drive the positioning reference block 3 to slide.

[0056] At the same time, combined with Figures 12 to 14 As shown, in this embodiment, a limiting block 32 is also provided on the side where the positioning reference block 3 is connected to the second driving part 31, and when the second driving part 31 drives the positioning reference block 3 to slide to the first state, the limiting block 32 abuts against the first simulation block 21 for limitation.

[0057] It should be noted that, based on this embodiment, there are multiple positioning reference blocks 3. Therefore, in specific implementation, as an example, the above-mentioned second driving unit 31 may also be multiple, and each second driving unit 31 is set in a one-to-one correspondence with each positioning reference block 3.

[0058] Furthermore, as a feasible example, the second drive unit 31 described above may also be a cylinder fixedly mounted on the machine base 1, and each positioning reference block 3 may also be connected to the cylinder rod of the corresponding cylinder by screwing or other suitable conventional fastening methods.

[0059] It is understandable that by setting the second driving unit 31 to drive the positioning reference block 3 to slide, this embodiment can realize the self-movement of the positioning reference block 3 in the tooling during contour detection. Compared with the method of manually driving the positioning reference block 3 to slide, this can obviously not only improve the efficiency of the inspection work, but also help to avoid the position deviation of the positioning reference block 3, which is conducive to improving the effectiveness of contour detection.

[0060] By setting the aforementioned limiting block 32, this embodiment can be adapted to the second driving unit 31 to drive the positioning reference block 3. When the positioning reference block 32 needs to enter the first state, the accuracy of the position of the positioning reference block 32 is further guaranteed, which is more conducive to improving the effectiveness of contour detection.

[0061] Continue by Figure 1 and combined Figures 8 to 10 ,as well as Figures 12 to 14 As shown, in some exemplary embodiments of this embodiment, a guide mechanism 5 and a locking mechanism 6 may be provided between the positioning reference block 3 and the sheet metal simulation block 2, for example.

[0062] In this embodiment, since the positioning reference block 3 is specifically slidably arranged relative to the first simulation block 21 in the sheet metal simulation block 3, the above-mentioned guide mechanism 5 and locking mechanism 6 are arranged between the positioning reference block 3 and the first simulation block 21.

[0063] Meanwhile, in terms of design, the aforementioned guiding mechanism 5 is adapted to guide the sliding of the positioning reference block 3 relative to the sheet metal simulation block 2, and the aforementioned locking mechanism 6 is adapted to lock and fix the positioning reference block 3 on the sheet metal simulation block 2 in the first state.

[0064] By setting a guide mechanism 5 and a locking mechanism 6 between the positioning reference block 3 and the first simulation block 21, it can be understood that, on the one hand, this embodiment can use the guide mechanism 5 to guide the sliding of the positioning reference block 3 relative to the first simulation block 21, which helps to ensure the stability of the sliding process of the positioning reference block 3.

[0065] On the other hand, this embodiment uses the locking mechanism 6 to lock the position of the positioning reference block 3 that has slid to the first state. This obviously also helps to provide stable support for the bright strip snap-fit ​​lip 104 on the outer water cutter 100, and can ensure the effectiveness of the contour inspection of the outer water cutter 100.

[0066] In specific implementations, in some exemplary embodiments, the guide mechanism 5 may include, for example, a guide pin 51 disposed on the first simulation block 21 and a guide hole 52 disposed on the positioning reference block 3.

[0067] The guide hole 52 is an elongated hole arranged along the sliding direction of the positioning reference block 3. The length direction of the elongated hole is the sliding direction of the positioning reference block 3, and the guide pin 51 passes through the guide hole 52. When the positioning reference block 3 is driven to slide by the second driving part 31, the guide pin 51 slides in the guide hole 52 along the length direction of the guide hole 52, thereby achieving the guiding function for the sliding of the reference positioning block 3.

[0068] It is understandable that the guide mechanism 5 adopts the above-mentioned matching structure of guide pin 51 and guide hole 52, which has the advantages of simple structure and easy design and implementation. At the same time, as an example, the above-mentioned guide pin 51 can be fixed to the first simulation block 21 by means of screw connection.

[0069] In specific implementations, in some exemplary embodiments, the locking mechanism 6 may include, for example, a locking hole 61 provided on the sheet metal simulation block 2, a connecting hole 62 provided on the positioning reference block 3, and a locking pin 63 provided in the connecting hole 62.

[0070] When the positioning reference block 3 is in the first state, the connecting hole 62 can be aligned with the locking hole 61, and the locking pin 63 can also be connected to the locking hole 61, so that the positioning reference block 3 can be locked and fixed on the sheet metal simulation block 2.

[0071] It is understandable that the locking mechanism 6, employing an alignable connecting hole 61 and a locking hole 62, and a locking pin 63 that can be further connected from the connecting hole 61 to the locking hole 62, also possesses advantages such as simple structure and ease of design and implementation. Furthermore, as an example, both the connecting hole 61 and the locking hole 62 can be threaded holes, and the locking pin 63 is screwed into the connecting hole 61 and can also be screwed into the locking hole 62.

[0072] Continue as Figures 4 to 7 and combined Figure 16 As shown, in some exemplary embodiments of this embodiment, a lifting drive unit 71 and a support block 7 driven by the lifting drive unit 71 may also be provided on the machine base 1.

[0073] The support block 7 is located below the outer water cutter 100 to be press-fitted and inspected, and when the support block 7 is driven to rise by the lifting drive unit 71, it can be supported at the bottom of the outer water cutter 100.

[0074] At this time, by providing a support block 7 that is driven to rise and fall by the lifting drive unit 71, and by ensuring that the support block 7 can be supported at the bottom of the outer water cutter 100 when it is driven to rise, it can be understood that, with reference to Figure 13 and Figure 14 As shown, this embodiment can further support the external water cutter 100 by using the support block 7 on the basis of the support of each sheet metal simulation block 3 to ensure the support strength of the external water cutter 100 during press-fitting. This can avoid problems such as the external water cutter 100 sinking, which would affect the press-fitting effect of the external water cutter. It can also avoid unnecessary interference to the subsequent contour inspection caused by the sinking of the external water cutter 100.

[0075] In specific implementation, the aforementioned support block 7 is positioned between the two limiting seats 13 and arranged along the length direction of the outer water cut 100. Also, as an example, two lifting drive units 71 can be used, with the two lifting drive units 71 fixedly arranged at the bottom of the machine base 1. Each lifting drive unit 71 is a cylinder and is connected to the support block 7 via a connecting block 73.

[0076] Continue as Figure 17 and Figure 18 As shown, in some exemplary embodiments of this embodiment, the inspection arm 41 in the contour detection component 4 is rotatably mounted on the machine base 1, and a sensing component (not shown in the figure) is also provided on the inspection arm 41.

[0077] With the flipping setting of the inspection arm 41, when in use, the inspection arm 41 can be positioned above the outer water cutter 100 as it flips, so that a contour gauge can be installed at the mounting point 42 on the inspection arm 41, thereby realizing the inspection of the contour of the outer water cutter 100.

[0078] The sensing component installed on the inspection arm 41 is adapted to detect the position of the positioning reference block 3 when the inspection arm 41 is flipped above the outer water cutter 100, so as to detect whether the positioning reference block 3 is in the first state.

[0079] It is understandable that by setting a sensing component on the inspection arm 41 of the contour inspection component 4, and enabling the sensing component to detect whether the positioning reference block 3 is in the first state when the inspection arm 41 is flipped above the outer water cutter 100, this embodiment can detect the position of the positioning reference block 3 during contour inspection, and can provide corresponding prompts based on the position detection to ensure that the position of the positioning reference block 3 meets the contour inspection requirements, thereby helping to ensure the reliability of the contour inspection.

[0080] In practical implementation, it is worth noting that the aforementioned inspection arm 41 can be formed by connecting multiple arm plates, or it can be a one-piece molded long arm structure. The aforementioned mounting point 42 can generally be a mounting hole provided on the inspection arm 41, for mounting a dial indicator for inspecting the 100° profile of the outer waterline.

[0081] Furthermore, since there are multiple positioning reference blocks 3 along with the fixedly installed first simulation blocks 21, and each positioning reference block 3 is correspondingly provided with a contour inspection component 4, the aforementioned sensing components located on each inspection arm 41 are also used to detect the position of the positioning reference block 3 at its respective location.

[0082] Meanwhile, as an example, the aforementioned sensing component can be a micro-motion contact switch or other mechanical, photoelectric, or other sensor device installed on the inspection arm 41. These sensor devices can be triggered by the positioning reference block 3 sliding to the first state to detect whether the positioning reference block 3 is in the position corresponding to the first state.

[0083] Furthermore, in practical implementation, the aforementioned sensors generally need to be connected to an alarm system to issue an alarm when any positioning reference block 3 fails to reach the position corresponding to the first state. This alarm system can be a dedicated system, or it can be integrated into the relevant control system of the outer water cutter 100 or the door production line.

[0084] Furthermore, regarding the aforementioned flipping arrangement of the inspection arm 41 on the machine tool 1, as an example, please refer to [reference needed]. Figure 17 and Figure 18 As shown, for example, one end of the inspection arm 41 can be hinged to the mounting base 43 via a flip shaft 45.

[0085] The mounting base 43 is fixed on the machine base 1, and a groove can be provided on the top of the mounting base 43. The flipping shaft 45 is located at one end of the groove, and the bottom of the end of the inspection arm 41 that is hinged to the flipping shaft 45 can be designed as an arc. This enables the inspection arm 41 to be flipped, and when the inspection arm 41 is flipped above the outer water cutter 100, it is also located in the groove on the top of the mounting base 43.

[0086] At this point, since the inspection arm 41 is located within the aforementioned groove, to further ensure the effectiveness of the external water-cutting 100 profile inspection, this embodiment may, for example, provide a locking handle 44 on the mounting base 43. The locking handle 44 is screwed onto one side of the aforementioned groove and can be screwed into the groove. When the inspection arm 41 is flipped into the groove, tightening the locking handle 44 will secure the inspection arm 41 firmly within the groove.

[0087] It is worth noting that, regarding the tooling in this embodiment, based on the above exemplary implementations, in specific implementation, as a preferred embodiment, it is still provided by... Figures 1 to 18 As shown, it may include, for example, a machine base 1, and a sheet metal simulation block 2, a positioning reference block 3, a contour inspection component 4, and a support block 7 disposed on the machine base 1.

[0088] The sheet metal simulation block 2 is used to support the outer water cutter 100 to be pressed and inspected. The sheet metal simulation block 2 includes a first simulation block 21 fixedly mounted on the machine base and a second simulation block 22 driven to slide relative to the machine base. Each sheet metal simulation block 2 has a contoured end 2a that is inserted into the mounting groove 103 on the outer water cutter 100. At the same time, the machine base 1 is provided with a first driving part 23 that drives each second simulation block 22 to slide.

[0089] The positioning reference block 3 consists of multiple blocks arranged corresponding to each of the first simulation blocks 21. Each positioning reference block 3 is slidably arranged relative to the corresponding first simulation block 21. The machine is provided with a second driving unit 31 that drives each positioning reference block 3 to slide. Under the drive of the second driving unit 31, each positioning reference block 3 can slide to a first state where it is supported by the bright strip snap-fit ​​lip 104 on the external water cutter 100, and to a second state where the support for the bright strip snap-fit ​​lip 104 is removed.

[0090] Furthermore, each positioning reference block 3 and its corresponding second simulation block 21 are provided with a guide mechanism 5 and a locking mechanism 6. The guide mechanism 5 is used to guide the sliding of the positioning reference block 3 relative to the second simulation block 21, and the locking mechanism 6 can lock and fix the positioning reference block 3 to the corresponding second simulation block 2 when the positioning reference block 3 is in the first state. At the same time, the support block 7 is driven to rise and fall by the lifting drive unit 71 and is located below the outer water cutter 100 to be pressed and inspected. When the support block 7 is driven to rise, it can support the bottom of the outer water cutter 100.

[0091] In addition, multiple contour inspection components 4 are provided corresponding to each positioning reference block 3. Each contour inspection component 4 includes an inspection arm 41 that is rotatably mounted on the machine base 1. The inspection arm 41 is provided with a mounting point 42 for mounting contour inspection fixtures, and a sensing component for detecting the position of the positioning reference block 3 is provided on the inspection arm 41. At the same time, when the positioning reference block 3 is in the first state, the inspection arm 41 can be rotated into the inspection position, and the contour of the external water cutter 100 can be inspected by the mounted contour inspection fixture.

[0092] In the preferred embodiment of the above tooling, the specific settings and arrangements of the sheet metal simulation block 2, the positioning reference block 3, the contour inspection component 4, the support block 7, etc. can still be referred to the descriptions in the above exemplary embodiments. Furthermore, in this preferred embodiment, the sheet metal simulation block 2, the positioning reference block 3, the contour inspection component 4, and the support block 7, etc., based on the beneficial effects brought about by their design, can also be referred to the descriptions in the above exemplary embodiments.

[0093] Meanwhile, taking the tooling in the above preferred embodiment as an example, and further combining it... Figures 13 to 15 As shown, when performing the press-fitting and contour inspection of the external water shear 100, the corresponding external water shear press-fitting inspection method includes the following steps.

[0094] Step 1: Place the sealing strip 101 of the outer water cutter 100 to be pressed and inspected on the sheet metal simulation block 2, so that the contour end 2a on the sheet metal simulation block 2 is inserted into the snap-fit ​​groove 103 on the sealing strip 101, and pre-install the bright strip 102 on the sealing strip 101.

[0095] Specifically, in step one, before setting the sealing strip 101, each first driving part 23 should drive the corresponding second simulation block 22 to slide out (that is, move towards the location where the outer water cutter 100 is set) until the contoured end 2a on each second simulation block 22 is flush with the contoured end 2a on each first simulation block 21. Of course, at this time, the positioning reference block 3 is in the non-extended state, and the inspection arm 41 in the contour inspection assembly 4 is also flipped to the side away from the location where the outer water cutter 100 is set.

[0096] Next, align the slot of the snap-fit ​​groove 103 on the sealing strip 101 with the contoured end 2a, and then press the sealing strip 101 to install it onto the sheet metal simulation block 2. Then, place the bright strip 102 on the sealing strip 101, and arrange the two sides of the bright strip 102 to correspond to the bright strip snap-fit ​​positions on the sealing strip 101 (or press it down slightly so that the sides of the bright strip can partially enter the snap-fit ​​structure on the sealing strip 101), thus pre-installing the bright strip 102 on the sealing strip 101.

[0097] Step 2: Press the bright strip 102 pre-installed on the sealing strip 101 to assemble the bright strip 102 and the sealing strip 101 together.

[0098] Specifically, in step two, for example, the outer surface of the bright strip 102 can be rolled manually using rollers to press the bright strip 102 into place with the sealing strip 101. Alternatively, rollers driven by a robotic arm or other automated equipment can be used to roll the bright strip 102 into place with the sealing strip 101, thereby completing the press-fit assembly of the outer water cutter 100.

[0099] In specific implementation, it is preferable to use a robotic arm or other automated equipment to drive the rollers for rolling, and the robotic arm or other automated equipment that drives the rollers for rolling can be the relevant equipment used in the existing water cutting and pressing assembly of car doors.

[0100] Step 3: Drive the positioning reference block 3 to slide relative to the sheet metal simulation block 2, and make the positioning reference block 3 slide to the first state to support the bright strip engagement lip 104 on the sealing strip 101.

[0101] Specifically, in step three, after the outer water cutter 100 is press-fitted, the second drive unit 31 drives each corresponding positioning reference block 3 to extend. With the guidance of the guide pin 51 and the abutment and limiting of the limit block 32, each positioning reference block 3 can be in the first state of supporting the bright strip snap-fit ​​lip 104 on the outer water cutter 100.

[0102] Next, tighten the locking pin 63 located in the connecting hole 62 so that the locking pin 63 enters the locking hole 61 on the first simulation block 21 until the locking pin 63 is rotated to a tight state.

[0103] Step 4: Move the inspection arm 41 in the contour inspection assembly 4 into the inspection position, and perform contour inspection on the assembled outer water cutter 100 using the contour inspection fixture installed on the inspection arm 41.

[0104] Specifically, in step four, the inspection arm 41 is first flipped over to the top of the outer water cutter 100. After the inspection arm 41 is flipped over, the position of the positioning reference block 3 is detected by the sensing component on the inspection arm 41, and the alarm system can be activated. If the positioning reference block 3 is detected to have slid to the position corresponding to the first state, the alarm is not triggered. However, if the positioning reference block 3 is not detected, the alarm can be triggered.

[0105] Once it is detected that the positioning reference block 3 has slid to the position corresponding to the first state, the dial indicator can be installed at the mounting point 42 on the inspection arm 41 to use the dial indicator to detect the 100° profile of the outer water cut. At this time, the relevant judgment criteria for the 100° profile of the outer water cut can refer to the relevant requirements in the existing vehicle door outer water cut profile detection, which will not be repeated here.

[0106] The tooling and its corresponding pressing inspection method in this embodiment can realize the pressing and contour inspection of the external water cutter 100 using the same tooling structure. It can not only reduce the number of processes and personnel required in the production process of the external water cutter 100, but also reduce the investment in tooling equipment required for the production of the external water cutter 100, which is conducive to reducing the production cost of the external water cutter 100 and has good practicality.

[0107] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
