Description
Technical Field
[0001] This utility model relates to the field of debugging tooling technology, specifically to an assembly and adjustment tooling and a door cover buffer block assembly and adjustment component. Background Technology
[0002] Buffer blocks are typically placed between the door hood and the body sheet metal of a vehicle. Buffer blocks serve to maintain limits, absorb energy, provide stable support, and adjust for surface differences.
[0003] In related technologies, the buffer block is a threaded cylindrical body. Assembly workers typically screw the buffer block into the threaded holes on the body sheet metal parts to complete the assembly. However, during the assembly process, assembly workers usually rotate the buffer block based on experience, and it is difficult to control the amount of screwing in. This can easily lead to over-installation or under-installation, resulting in poor accuracy and affecting the performance. Utility Model Content
[0004] In view of this, the present invention provides an assembly and adjustment fixture to solve the problem of poor installation accuracy of the buffer block.
[0005] Firstly, this utility model provides an assembly and adjustment fixture, comprising:
[0006] The fastener includes: a body portion and at least one mounting portion connected to the body portion; one side surface of the mounting portion forms an abutment surface adapted to abut against a target feature surface to position the fastener in place.
[0007] An adjusting member is movably connected to a fixed member along a first direction. The adjusting member has an initial state connected to the fixed member, an adjusting state in which it moves relative to the fixed member along the first direction when compressed, and a measuring state in which it remains relatively stationary with respect to the fixed member after being compressed.
[0008] Beneficial effects: The assembly and adjustment fixture provided in this embodiment, by setting a fixing member, forms an abutment surface on one side of the mounting part of the fixing member, which is adapted to abut against the target feature surface to position the fixing member; thereby positioning the fixing member in a preset position. An adjusting member is also provided, which is movably connected to the fixing member along a first direction. The adjusting member has an initial state connected to the fixing member, an adjustment state in which it moves relative to the fixing member along the first direction when compressed, and a measurement state in which it remains relatively stationary with the fixing member after compression. Thus, through the relative movement of the adjusting member and the fixing member, the assembly and adjustment fixture can be moved to a suitable target position. The dimensions of the assembly and adjustment fixture in the measurement state can be used as a reference to compare the installation of other external structures, ensuring that the dimensions of other external structures are based on the dimensions of the assembly and adjustment work, thus guaranteeing assembly and adjustment accuracy and improving assembly and adjustment efficiency.
[0009] In one alternative embodiment, the fastener further includes:
[0010] An anti-detachment unit is provided in the mounting part and / or the body part, and the anti-detachment unit is adapted to maintain the contact between the contact surface and the target feature surface.
[0011] In one alternative implementation, the anti-detachment unit includes a magnetic element.
[0012] Beneficial effects: The anti-detachment unit is suitable for maintaining contact between the contact surface and the target feature surface, improving installation stability. It also ensures a tight fit between the contact surface and the target feature surface, accurate positioning, avoids shaking, and facilitates subsequent measurements.
[0013] In one optional embodiment, the mounting portion has a magnetic component mounting hole, which is suitable for mounting a magnetic component, and the magnetic component is disposed without extending beyond the contact surface along the first direction.
[0014] Beneficial effects: The magnetic component is installed in the magnetic component mounting hole, and the magnetic component does not extend beyond the abutment surface along the first direction. This ensures a tight fit between the fixing component and the target feature surface, avoids errors caused by the protrusion of the magnetic component during the measurement process, prevents the magnetic component from interfering with the measurement results, and improves data accuracy.
[0015] In one alternative embodiment, the fastener further includes a positioning part adapted to position the fastener 1 at the assembly position with the target feature surface.
[0016] Beneficial effects: When the fixture is adsorbed onto the feature surface, the installation notch can be cleverly used as a positioning reference. By setting a positioning part on the fixture, it can be precisely fitted with the installation notch, which can ensure that the fixture is accurately aligned with the target feature surface.
[0017] In one optional embodiment, the adjusting member includes: a mounting ring having a mounting cavity formed through it along a first direction, and the main body portion being at least partially inserted into the mounting cavity;
[0018] The outer periphery of the main body is provided with multiple grooves, which are spaced apart along the first direction.
[0019] The mounting ring has a snap-fit portion on the side facing the main body, which is adapted to engage with the groove.
[0020] In the adjustment state, the snap-fit part is adapted to switch sequentially within multiple grooves along the first direction.
[0021] Beneficial effects: During the closing process, the door covers press against the fixture, causing the locking part of the adjusting component to move between multiple grooves, thereby enabling fine-tuning of the fixture and adjusting the relative positions of the fixing and adjusting components. Simultaneously, after the door covers are fully closed, the locking part is ensured to engage within one of the grooves, guaranteeing the fixture's stability and maintaining its dimensions. This allows for easy comparison of the buffer block's assembly and adjustment dimensions using this measurement.
[0022] In one alternative embodiment, a slide rail portion is further provided on the outer periphery of the main body portion, the slide rail portion extends along a first direction, and a plurality of grooves are formed on the slide rail portion.
[0023] A guide portion is also formed on the side of the mounting ring facing the main body, which is adapted to guide the slide rail portion to move in the first direction.
[0024] Beneficial effects: The precise cooperation between the guide part and the slide rail part further improves the movement stability of the adjustment part, ensures the smoothness of the tooling during the adjustment process, and avoids jamming. At the same time, the guide part can guide the slide rail part, so that the slide rail part maintains a straight trajectory during the movement, which is more conducive to ensuring adjustment accuracy.
[0025] In one alternative embodiment, one of the mounting parts is further provided with a first verification part, the side of the first verification part opposite to the adjusting member forming a first verification surface;
[0026] The mounting ring is also provided with a second verification part, and the side of the second verification part opposite to the fastener forms a second verification surface;
[0027] The first verification unit and the second verification unit are arranged correspondingly along the first direction.
[0028] Beneficial effects: The first and second verification parts are set correspondingly along the first direction, so that the distance between the first and second verification surfaces along the first direction can reflect the size of the tooling, thereby truly reflecting the size of the buffer block. At the same time, it is convenient to use the first and second verification parts to compare the size of the buffer block, thus achieving rapid verification.
[0029] In one optional implementation, in the initial state, the distance between the first verification surface and the second verification surface is H1;
[0030] In the measurement state, the distance between the first calibration surface and the second calibration surface is H2, which satisfies: H1≥H2+5mm.
[0031] In one alternative embodiment, the body portion is formed with a clearance hole through a first direction, the clearance hole being adapted to allow an external structure to pass through.
[0032] Beneficial effects: A clearance hole is formed through the main body along the first direction, allowing the buffer block to pass through it. This enables the tooling's contact surface to be enlarged even with a sufficiently large feature surface. Therefore, it eliminates the need to remove the tooling. After the cover is closed, the tooling remains in its original position during measurement. The cover can then be reopened, and the buffer block can be installed directly through the clearance hole. This facilitates fine-tuning and calibration of the buffer block, simplifying the operation and improving efficiency. It allows for direct installation of the buffer block without removing the tooling, making it simpler and more efficient.
[0033] Secondly, this utility model also provides a door cover buffer block assembly, comprising:
[0034] Sheet metal parts, the sheet metal parts are provided with buffer block mounting holes, and the sheet metal parts form a feature surface around the outer periphery of the buffer block mounting holes;
[0035] Buffer block, installed in the buffer block mounting hole;
[0036] Door cover, suitable for opening and closing relative to sheet metal parts;
[0037] When installing the buffer block, the aforementioned mounting fixture is suitable for adsorption onto the feature surface;
[0038] The door cover moves from the open state to the closed state, which is suitable for pressing the assembly tooling, so that the assembly tooling is adjusted from the initial state to the measurement state;
[0039] The buffer block is adapted to adjust the size of its relative feature surface according to the size of the adjusting element in the measuring state.
[0040] Since the door cover buffer block assembly includes an assembly tooling and has the same effect as the assembly tooling, it will not be described in detail here. Attached Figure Description

[0059] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0060] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0061] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0062] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0063] Vehicles vibrate continuously during operation, causing the hood, tailgate, and other door covers to sway. By installing buffer blocks between the door covers and the body panels, energy absorption and cushioning are achieved. Furthermore, because precise control of gaps between components is crucial during vehicle manufacturing and assembly, the buffer blocks also help adjust for surface differences and maintain limits. Additionally, the buffer blocks provide collision protection during the closing of the door covers.
[0064] In related technologies, the buffer block is a threaded cylindrical body. Assembly workers usually screw the buffer block into the screw holes on the body sheet metal parts to complete the assembly of the buffer block. However, in the process of assembling the buffer block, the assembly workers rotate the buffer block according to experience, and it is difficult to control the amount of screwing in. It is easy to install too much or not install properly, resulting in poor accuracy and thus affecting the use effect. The following three installation and adjustment methods are often used in related technologies: (1) Shaking and pressing method. This method mainly verifies the installation and adjustment effect by manually shaking and pressing the position of the door cover buffer block. However, this method cannot accurately judge the rigid support strength, resulting in position locking failure and easy displacement of the opening and closing parts. (2) Fixed installation number of turns method. This method directly specifies the number of installation turns of the buffer block, ignoring the differences in actual working conditions (such as manufacturing errors and part wear). There is a situation where the buffer block cannot compensate for the surface difference by adjustment and loses the height adjustment function. (3) Paper pulling inspection method. This method can make up for the shortcomings of the first two methods, but it is complicated and inefficient. The paper pulling inspection method requires repeated disassembly and verification, which wastes time and depends on human experience. It is impossible to quantify the gap value and it is difficult to guarantee the stability of the buffer energy absorption effect.
[0065] To overcome the above-mentioned defects, the assembly and adjustment fixture provided in the embodiments of this utility model can improve the assembly and adjustment efficiency of the buffer block, reduce the labor cost and operation time in the manufacturing process, and ensure the assembly and adjustment accuracy.
[0066] The following is combined with Figures 1 to 12 The following describes embodiments of the present invention.
[0067] According to an embodiment of the present invention, in one aspect, an assembly tooling is provided, including: a fixing member 1, the fixing member 1 including: a body part 11 and at least one mounting part 13 connected to the body part 11; a contact surface 132 is formed on one side of the mounting part 13, the contact surface 132 being adapted to contact a target feature surface to position the mounting position of the fixing member 1.
[0068] Adjusting member 2 is movably connected to fixing member 1 along a first direction. Adjusting member 2 has an initial state connected to fixing member 1, an adjustment state in which it moves relative to fixing member 1 along the first direction when compressed, and a measurement state in which it remains relatively stationary with fixing member 1 after being compressed.
[0069] The assembly and adjustment fixture provided in this embodiment uses a fixing member 1. One side of the mounting portion 13 of the fixing member 1 forms an abutment surface 132, which is adapted to abut against a target feature surface to position the fixing member 1 at a preset location. An adjusting member 2 is also provided. The adjusting member 2 is movably connected to the fixing member 1 along a first direction. The adjusting member 2 has an initial state connected to the fixing member 1, an adjustment state where it moves relative to the fixing member 1 along the first direction under pressure, and a measurement state where it remains relatively stationary with respect to the fixing member 1 after being pressed. Through the relative movement of the adjusting member 2 and the fixing member 1, the assembly and adjustment fixture can be moved to a suitable target position. The dimensions of the assembly and adjustment fixture in the measurement state can be used as a reference to compare the installation of other external structures, ensuring that the dimensions of other external structures are based on the dimensions of the assembly and adjustment work, thus guaranteeing assembly and adjustment accuracy and improving assembly and adjustment efficiency. To facilitate understanding of the assembly and adjustment fixture provided in this embodiment, the application environment of this embodiment is first described: This fixture is suitable for the installation and adjustment of door cover buffer blocks for various vehicle models, ensuring precise fit between the buffer block and the sheet metal parts, and improving assembly quality. The buffer block is positioned between the door cover and the body sheet metal parts. The door cover is adapted to rotate relative to the body sheet metal parts to achieve the opening and closing function of the door cover. In the open state of the door cover, the assembly and adjustment fixture of this embodiment is first fixed to the feature surface 31 of the body sheet metal parts. Then, the door cover is closed normally. During the closing process, the door cover will squeeze the fixture, causing the adjusting part 2 to move under pressure. When the door cover is closed in place, the size of the protrusion of the fixture relative to the feature surface 31 of the body sheet metal parts directly reflects the installation state of the buffer block. By comparing the installation, the position of the buffer block can be precisely adjusted to ensure that the gap between the buffer block and the sheet metal parts meets the design requirements, ensuring assembly and adjustment accuracy, thereby improving assembly accuracy and stability. Using the assembly and adjustment fixture of this embodiment can greatly improve the efficiency of buffer block assembly and adjustment, and ensure the function of the buffer block.
[0070] The assembly and adjustment fixture in this embodiment is suitable for installing and adjusting the buffer block 4 installed on the sheet metal part 3.
[0071] The abutment surface 132 is adapted to abut against the target feature surface to position the fastener 1. In a specific application, the sheet metal part 3 has a buffer block mounting hole 33 for mounting the buffer block 4, and the sheet metal part 3 forms a feature surface 31 around the outer periphery of the buffer block mounting hole 33; in this embodiment, the feature surface 31 is the target feature surface; the fastener 1 is adapted to be detachably connected to the feature surface 31; the buffer block 4 is adapted to adjust its size relative to the feature surface 31 according to the size of the adjusting member 2 in the measuring state.
[0072] The sheet metal part 3 has a buffer block mounting hole 33 for mounting the buffer block 4. The sheet metal part 3 forms a feature surface 31 around the outer periphery of the buffer block mounting hole 33. By connecting the fixing part 1 to the feature surface 31, the feature surface 31 can be used as a positioning base to ensure that the fixing part 1 and the feature surface 31 fit tightly, thereby improving the movement accuracy of the adjusting part 2 and better meeting the dimensional accuracy requirements of the buffer block 4 at its installation position.
[0073] The fastener 1 and the feature surface 31 are detachably connected. The connection method can be adhesive, magnetic connection, threaded connection, etc., which facilitates quick installation and disassembly and improves work efficiency. In this embodiment, the fastener 1 and the feature surface 31 are connected by magnetic connection.
[0074] The adjusting component 2 is movably connected to the fixing component 1. The adjusting component 2 is connected to the fixing component 1 through a structure such as a slide rail, ensuring that it moves smoothly along the first direction when under pressure and remains stable in the measurement state, which facilitates accurate reading of dimensional data.
[0075] The adjusting member 2 has an initial state connected to the fixing member 1, an adjustment state in which it moves relative to the fixing member 1 along a first direction when under pressure, and a measurement state in which it remains relatively stationary with respect to the fixing member 1 after being under pressure. The initial state refers to the natural position of the adjusting member 2 and the fixing member 1 when no external force is applied. The adjustment state refers to the state in which the adjusting member 2 moves relative to the fixing member 1 along the first direction after being subjected to the pressure of the door cover. The measurement state refers to the position in which the adjusting member 2 stops moving when the door cover is in place, at which point the adjusting member 2 remains stationary in the new position, facilitating the reading of accurate data. The buffer block 4 is adapted to adjust the size of its relative feature surface 31 according to the size of the adjusting member 2 in the measurement state, ensuring the assembly accuracy of the buffer block 4 and the sheet metal parts and improving the assembly quality.
[0076] In this embodiment, the surface of the mounting part 13 facing the feature surface 31 forms an abutment surface 132, and the abutment surface 132 matches the feature surface 31.
[0077] In some embodiments, the fastener 1 further includes:
[0078] An anti-detachment unit is provided in the mounting part 13 and / or the body part 11. The anti-detachment unit is adapted to maintain the contact between the contact surface 132 and the target feature surface.
[0079] In some embodiments, the anti-detachment unit includes a magnetic element.
[0080] In this embodiment, a magnetic component is disposed on the mounting portion 13 and / or the body portion 11. The magnetic component is adapted to cause the fixing component 1 to be attracted to the sheet metal part 3 and to make the contact surface 132 fit with the feature surface 31.
[0081] The mounting part 13 forms an abutment surface 132 on the side facing the feature surface 31. The abutment surface 132 matches the feature surface 31, thereby ensuring that the fastener 1 and the sheet metal part 3 fit tightly together and that the installation position of the fastener 1 and the sheet metal part 3 is accurate and can truly reflect the size of the buffer block 4.
[0082] The magnetic component can be disposed on the mounting part 13 or on the body part 11. In this embodiment, the magnetic component is disposed on the mounting part 13 to ensure tight adhesion between the fixing part 1 and the sheet metal part 3, thereby improving installation stability. It also ensures that the contact surface 132 and the feature surface 31 are tightly fitted, ensuring accurate positioning, preventing shaking, and facilitating subsequent measurements.
[0083] In some embodiments, the mounting portion 13 has a magnetic component mounting hole 131, which is suitable for mounting a magnetic component, and the magnetic component is disposed along the first direction without extending beyond the abutment surface 132.
[0084] The magnetic component is installed in the magnetic component mounting hole 131, and the magnetic component does not extend beyond the abutment surface 132 in the first direction. This ensures a tight fit between the fixing component 1 and the sheet metal component 3, and also ensures a tight fit between the abutment surface 132 and the feature surface 31. This avoids errors caused by the protrusion of the magnetic component during measurement, prevents the magnetic component from interfering with the measurement results, and improves the accuracy of the data.
[0085] In some embodiments, the fastener 1 further includes a positioning part 12, which is adapted to position the fastener 1 at the assembly position with the target feature surface.
[0086] Combination Figure 6 As shown, the assembly position of the target feature surface refers to the fact that the sheet metal part 3 also has an installation notch 32, which is suitable for communicating with the buffer block mounting hole 33.
[0087] The positioning part 12 is shaped to match the mounting notch 32 and is adapted to be inserted into the mounting notch 32;
[0088] The positioning part 12 is suitable for positioning the assembly position of the fastener 1 and the sheet metal part 3.
[0089] Since the buffer block 4 is threaded, the sheet metal part 3 has an installation notch 32, which makes it easy for the buffer block 4 to be screwed into the installation notch 32 with the installation notch 32 as the starting point for screwing in.
[0090] When the fixture is adsorbed onto the feature surface 31, the mounting notch 32 can be cleverly used as a positioning reference. By setting the positioning part 12 on the fixing part 1, it can be precisely fitted with the mounting notch 32, thus ensuring that the fixing part 1 and the sheet metal part 3 are precisely aligned.
[0091] In some embodiments, combined with Figure 3As shown, the adjusting member 2 includes: a mounting ring 21, which has a mounting cavity 23 extending through it in a first direction, and the main body 11 is at least partially inserted into the mounting cavity 23;
[0092] The outer periphery of the main body 11 is provided with a plurality of grooves 141, which are spaced apart along a first direction.
[0093] The mounting ring 21 has a snap-fit portion 25 on the side facing the body portion 11, and the snap-fit portion 25 is adapted to snap-fit with the groove 141.
[0094] In the adjustment state, the snap-fit portion 25 is adapted to switch sequentially within a plurality of grooves 141 along a first direction.
[0095] The mounting ring 21 has a mounting cavity 23 formed through it in the first direction. The main body 11 is adapted to be inserted into the mounting cavity 23, thereby realizing the assembly of the fixing member 1 and the adjusting member 2.
[0096] The snap-fit part 25 is adapted to snap-fit with the groove 141 to form an interlocking structure, and a certain force needs to be applied to move it up and down.
[0097] During the closing process, the door covers press against the fixture, causing the locking part 25 of the adjusting component 2 to move between multiple grooves 141, thereby enabling fine-tuning of the fixture and adjusting the relative position of the fixing component 1 and the adjusting component 2. Simultaneously, after the door covers are fully closed, the locking part 25 is secured within one of the grooves 141, ensuring the fixture is stably fixed and its dimensions remain unchanged. This allows for easy comparison of the adjustment dimensions of the buffer block 4.
[0098] Through the precise engagement of the snap-fit part 25 and the groove 141, the adjusting part 2 can be fixed in multiple positions, realizing flexible adjustment of the tooling and ensuring that a precise assembly state can be maintained under different working conditions.
[0099] In this embodiment, multiple scoring grooves 141 are evenly spaced along a first direction, so that the scoring grooves 141 can function as scale lines, making it convenient for the operator to read the scale values. The range of the scale lines can be reasonably adjusted according to actual needs. For example, a scoring groove can be set at 1 mm intervals to facilitate more precise adjustment of the tooling position.
[0100] In some embodiments, combined with Figure 3 As shown, a slide rail 14 is also provided on the outer periphery of the main body 11. The slide rail 14 extends along the first direction, and a plurality of grooves 141 are formed on the slide rail 14.
[0101] The mounting ring 21 also has a guide portion 24 formed on the side facing the body portion 11, which is adapted to guide the slide rail portion 14 to move in the first direction.
[0102] The precise cooperation between the guide part 24 and the slide rail part 14 further enhances the movement stability of the adjusting part 2, ensuring the smoothness of the tooling during the adjustment process and avoiding jamming. At the same time, the guide part 24 can guide the slide rail part 14, so that the slide rail part 14 maintains a straight trajectory during the movement, which is more conducive to ensuring the adjustment accuracy.
[0103] In this embodiment, multiple grooves 141 are formed on the slide rail 14. The surface of the slide rail 14 is smooth, which reduces frictional resistance and ensures that the snap-fit part 25 can switch smoothly between the grooves 141.
[0104] Furthermore, in this embodiment, the main body 11 is provided with a plurality of slide rails 14 in the circumferential direction, thereby further ensuring the stability of the adjusting member 2 during the adjustment process.
[0105] In some embodiments, combined with Figures 2 to 4 As shown, one of the mounting parts 13 is also provided with a first verification part 133, and the first verification part 133 forms a first verification surface 1331 on the side opposite to the adjusting member 2.
[0106] The mounting ring 21 is also provided with a second verification part 22, and the side of the second verification part 22 facing away from the fixing member 1 forms a second verification surface 221;
[0107] The first verification unit 133 and the second verification unit 22 are arranged correspondingly along the first direction.
[0108] Multiple mounting parts 13 are provided on the outer periphery of the main body 11. One of the mounting parts 13 is also provided with a first verification part 133. The first verification part 133 forms a first verification surface 1331 on the side away from the adjusting member 2. Correspondingly, the second verification part 22 on the mounting ring 21 forms a second verification surface 221 on the side away from the fixing member 1. The first verification part 133 and the second verification part 22 are arranged correspondingly along the first direction. The distance between the first verification surface 1331 and the second verification surface 221 along the first direction is used to reflect the size of the tooling, thereby truly reflecting the size of the buffer block 4. At the same time, it is convenient to use the first verification part 133 and the second verification part 22 to compare the size of the buffer block 4, so as to achieve rapid verification.
[0109] In some embodiments, combined with Figure 4 As shown, in the initial state, the distance between the first verification surface 1331 and the second verification surface 221 is H1;
[0110] Combination Figure 5 As shown, in the measurement state, the distance between the first verification surface 1331 and the second verification surface 221 is H2, which satisfies: H1≥H2+5mm.
[0111] Additionally, the size of the buffer block 4 exposed on the feature surface 31 along the first direction is h, which satisfies: h = H2 ± 1 mm.
[0112] In the initial state, the fixing part 1 and the adjusting part 2 are first assembled together to form a testing fixture. At this time, it is necessary to ensure that H1≥H2+5mm so that the adjusting part 2 can be moved under pressure during the measurement process.
[0113] When the adjusting element 2 is moved to the measuring state, the H2 value accurately reflects the actual size of the buffer block 4. By comparing H2 with h, it is convenient to make precise adjustments to the buffer block 4.
[0114] Combination Figure 10 As shown, this is a scenario where the adjustment component 2 is moved to the measurement state, and the size of the buffer block 4 is checked using the assembly and adjustment fixture provided in this embodiment, so as to ensure its accurate positioning in vehicle assembly.
[0115] In some modified embodiments, combined with Figure 11 , Figure 12 As shown, the main body 11 has a clearance hole 15 formed through it along the first direction, and the buffer block 4 is adapted to pass through the clearance hole 15.
[0116] A clearance hole 15 is formed through the main body 11 along the first direction. The buffer block 4 is adapted to pass through the clearance hole 15, thereby allowing the abutment surface 132 of the tooling to be enlarged when the feature surface 31 is sufficiently large. This eliminates the need to remove the tooling. After the cover is closed, the tooling remains in its original position during measurement. The cover can then be reopened, and the buffer block 4 can be installed directly through the clearance hole 15. This facilitates fine-tuning and calibration of the buffer block 4, simplifies the operation process, and improves efficiency. The buffer block 4 can be installed directly without removing the tooling, making it simpler and more efficient.
[0117] According to an embodiment of the present invention, another aspect provides a door cover buffer block assembly, comprising:
[0118] Sheet metal part 3, sheet metal part 3 has a buffer block mounting hole 33, and sheet metal part 3 forms a feature surface 31 around the outer periphery of the buffer block mounting hole 33;
[0119] Buffer block 4 is installed in buffer block mounting hole 33;
[0120] Door cover, suitable for opening and closing relative to sheet metal parts in three directions;
[0121] When installing the buffer block 4, the above-mentioned mounting fixture is suitable for adsorption on the feature surface 31;
[0122] The door cover moves from the open state to the closed state, which is suitable for pressing the assembly tooling, so that the assembly tooling is adjusted from the initial state to the measurement state;
[0123] The buffer block 4 is adapted to adjust the size of its relative feature surface 31 according to the size of the adjusting member 2 in the measuring state.
[0124] The following describes the specific application process of the assembly and adjustment tooling in this embodiment:
[0125] Step 1: As Figure 4 As shown, firstly, the adjusting component 2 and the fixing component 1 are assembled together to form a testing fixture, ensuring that the measurement range H1 is greater than the theoretical installation height of the buffer block, preferably satisfying H1≥H2+5mm;
[0126] Step 2: As Figure 8 As shown, the fastener 1 is magnetically attached to the feature surface 31 to ensure that the positioning part 12 matches the mounting notch 32, thereby ensuring accurate positioning;
[0127] Step 3: Close the door, ensuring it is fully locked. During the closing process, if... Figure 9 As shown, the adjusting component 2 is moved to the measuring state under pressure; after the door is unlocked, the installation and adjustment fixture is removed, and the height of H2 at this time is the actual assembly size of the current buffer block 4;
[0128] Step 4: Based on the design requirements for the fit between the buffer block 4 and the feature surface 31, move the adjusting component 2 up and down to adjust the tooling. Then place the tooling at the previously measured point, and the buffer block 4 can be directly installed for comparison.
[0129] The assembly and adjustment fixture provided in this embodiment has a simple structure and is easy to operate, which can greatly reduce labor costs and operating hours in the manufacturing process. It facilitates the standardization and normalization of operator work. In addition, the assembly and adjustment fixture provided in this embodiment adopts a magnetic structure, which can be reused multiple times and can be used for multiple vehicle models and projects, greatly reducing the investment in manufacturing tooling costs and making it more widely applicable.
