Description

Technical Field

[0001] This application relates to the field of automotive tooling, specifically to a separate positioning and adjustment device for an automotive radiator frame and a front buffer beam. Background Technology

[0002] Automobiles are highly integrated products, composed of 14,000 to 20,000 parts. Due to inherent manufacturing errors in body components, these errors inevitably accumulate and propagate during assembly, leading to deviations between the final component dimensions and design values. This results in quality issues such as assembly interference and misaligned clearances. The front of the car has the longest dimensional chain and the most parts involved in the matching process. Accumulated and propagated errors during assembly often cause poor matching quality between the front bumper assembly and headlight assembly and their respective parts, sometimes even preventing the assembly of these components altogether. Utility Model Content

[0003] Therefore, there is a need to provide a separate positioning and adjustment device for the automotive radiator frame and the front buffer beam to solve the problem of mutual interference and inaccuracy of parts caused by the accumulation and transmission of errors during the automotive assembly process in the prior art.

[0004] To achieve the above objectives, the inventor provides a separate positioning and adjustment device for an automotive radiator frame and a front bumper beam, comprising:

[0005] The dispensing platform is equipped with an adjustable height support assembly to support the water tank frame;

[0006] A beam limiting mechanism, comprising at least one pair of vertical limiting components, wherein the pair of vertical limiting components are arranged longitudinally and facing each other; the vertical limiting component comprises a first mounting base and a vertical rod, wherein the first mounting base is adjustable laterally and longitudinally on the assembly platform, and the vertical rod is erected on the first mounting base;

[0007] A frame limiting mechanism includes at least one pair of vertical limiting components and at least two pairs of lateral limiting components arranged longitudinally. The pairs of vertical limiting components are arranged longitudinally and facing each other, and are located in the area between the pairs of vertical limiting components of the beam limiting mechanism. The pairs of lateral limiting components are arranged laterally and facing each other. The lateral limiting components include a second mounting base, a crossbar, and a driving mechanism. The second mounting base is longitudinally and vertically adjustable at the assembly platform. The driving mechanism is located at the second mounting base and connected to the crossbar to drive the crossbar to move laterally.

[0008] In some embodiments, an auxiliary positioning seat is provided on one side of the vertical limiting component of the beam limiting mechanism, and the auxiliary positioning seat is located on the side of the vertical limiting component of the beam limiting mechanism facing laterally, so as to jointly support the front buffer beam with the first mounting seat of the vertical limiting component.

[0009] In some embodiments, the support assembly includes a support base, which includes a base body and a plurality of gaskets. The gaskets are stacked on top of the base body and vertically locked to the assembly table by bolts. The number of stacked gaskets is selected to adjust the height of the support base.

[0010] In some embodiments, the support is provided in four sets.

[0011] In some embodiments, the first mounting base is disposed on the sub-assembly table via a first adjustment structure. The first adjustment structure includes a first fixed base, a first intermediate base, and a plurality of gaskets. The first fixed base is fixedly disposed on the sub-assembly table. The first intermediate base includes a first vertical surface facing the longitudinal direction and a second vertical surface facing the transverse direction. Some gaskets are stacked between the first fixed base and the first vertical surface of the first intermediate base and are longitudinally locked by bolts. The number of stacked gaskets is selected to adjust the longitudinal position of the first mounting base. Some gaskets are stacked between the second vertical surface of the first intermediate base and the first mounting base and are transversely locked by bolts. The number of stacked gaskets is selected to adjust the transverse position of the first mounting base.

[0012] In some embodiments, the second mounting base is disposed on the sub-assembly table via a second adjustment structure. The second adjustment structure includes a second fixed base, a second intermediate base, and a plurality of gaskets. The second fixed base is fixedly disposed on the sub-assembly table. The second intermediate base includes a third vertical surface facing longitudinally and a horizontal surface facing upward. Some gaskets are stacked between the third vertical surface of the second fixed base and the second intermediate base and are longitudinally locked by bolts. The number of stacked gaskets is selected to adjust the longitudinal position of the second mounting base. Some gaskets are stacked between the horizontal surface of the second intermediate base and the second mounting base and are vertically locked by bolts. The number of stacked gaskets is selected to adjust the vertical position of the second mounting base.

[0013] In some embodiments, the gaskets include gaskets of various thicknesses, including 2 mm, 1 mm, 0.5 mm, 0.2 mm, and 0.1 mm.

[0014] In some embodiments, the drive mechanism is a linear motor, a cylinder, or a hydraulic cylinder.

[0015] In some embodiments, the water tank frame is provided with at least one set of first vertical holes and a pair of horizontal holes;

[0016] The first vertical hole group is located on the top surface of the water tank frame, including a first circular vertical hole and a first allowance vertical hole, so that the paired vertical limiting components of the frame limiting mechanism can pass through one by one, and the first allowance vertical hole has a margin for the vertical rod to move in the longitudinal direction.

[0017] The transverse hole group includes transverse holes arranged along the longitudinal direction and at least one spare transverse hole; pairs of transverse hole groups are respectively provided on both sides of the water tank frame, and the transverse holes of the pairs of transverse hole groups allow one pair of transverse limiting components of the frame limiting mechanism to pass through one by one, and the spare transverse holes of the pairs of transverse hole groups allow the other pair of transverse limiting components of the frame limiting mechanism to pass through one by one, and the spare transverse holes have a margin for the movement of the transverse rod in the longitudinal direction.

[0018] In some embodiments, the front buffer beam is provided with at least one set of second vertical holes. The second vertical hole set includes a second circular vertical hole and a second allowance vertical hole arranged along the longitudinal direction, and is respectively provided at both ends of the front buffer beam so that the paired vertical limiting components of the beam limiting mechanism can pass through one by one. The second allowance vertical hole has a margin for the vertical rod to move in the longitudinal direction.

[0019] Unlike existing technologies, the vertical limiting component of the automotive radiator frame and front buffer beam assembly positioning and adjustment device described in the above technical solution features an adjustable-height support component on its assembly platform. This support component can temporarily support the radiator frame, facilitating subsequent position adjustments. The height of the support component is adjustable, allowing it to be adjusted to a suitable height based on the frame limiting mechanism, enabling initial positioning of the radiator frame's vertical movement, longitudinal rotation, and lateral rotation. The pair of vertical limiting components in the beam limiting mechanism restrict the placement of the front buffer beam relative to the radiator frame. Furthermore, since the first mounting base of the vertical limiting component is adjustable laterally and longitudinally on the assembly platform, its position in the lateral and longitudinal directions can be adjusted to compensate for errors as needed. The first mounting base also restricts the vertical movement of the front buffer beam, thus allowing the uprights to confine the front buffer beam to a specific position, positioning the front buffer beam in all six degrees of freedom. The pair of vertical and horizontal limiting components of the frame limiting mechanism can restrict the placement of the water tank frame. Since the first mounting base of the vertical limiting component can be adjusted horizontally and vertically on the assembly platform, its position in the horizontal and vertical directions can be adjusted according to the actual error compensation, thereby limiting the horizontal movement, vertical movement, and vertical rotation of the water tank frame. Since the second mounting base of the horizontal limiting component can be adjusted vertically and vertically on the assembly platform, its position in the vertical and vertical directions can be adjusted according to the actual error compensation, and then driven by the drive mechanism to horizontally penetrate the water tank frame, limiting the vertical movement, horizontal rotation, and vertical rotation of the water tank frame, thus collectively restricting the water tank frame to a specific position. Therefore, the vertical limiting component's automotive radiator frame and front buffer beam separate assembly positioning adjustment device can quickly adjust the relative position of the radiator frame and front buffer beam according to the matching dimensions of the front body and the final assembly parts, thereby compensating for the accumulated and transmitted errors during the front assembly of the vehicle and improving the matching quality of the front bumper assembly and headlight assembly with the matching parts.

[0071] Automobiles are highly integrated products, composed of 14,000 to 20,000 parts. Due to inherent manufacturing errors in body components, these errors inevitably accumulate and propagate during assembly, leading to deviations between the final component dimensions and design values. This results in quality issues such as assembly interference and misaligned clearances. The front of the car has the longest dimensional chain and the most parts involved in the matching process. Accumulated and propagated errors during assembly often cause poor matching quality between the front bumper assembly and headlight assembly and their respective parts, sometimes even preventing the assembly of these components altogether.

[0072] Therefore, the accumulation and transmission of errors during the automotive assembly process in the prior art leads to the problem of mutual interference and inaccuracy of parts. To address this, this utility model provides a separate assembly positioning and adjustment device for automotive radiator frame and front buffer beam, which is used to assist manual completion of the connection operation between the radiator frame and the front buffer beam. In particular, it can adjust the relative position of the radiator frame and the front buffer beam to compensate for assembly errors.

[0073] Please see Figure 1 In a specific embodiment, the automotive water tank frame and front buffer beam separate assembly and positioning adjustment device includes a separate assembly platform 1, a beam limiting mechanism, and a frame limiting mechanism. The separate assembly platform 1 is an operating platform. The beam limiting mechanism is used to limit the position and positioning of the front buffer beam 10, and the frame limiting mechanism is used to limit the position and positioning of the water tank frame 9.

[0074] The dispensing platform 1 is equipped with an adjustable height support component to support the water tank frame 9; the beam limiting mechanism includes at least one pair of vertical limiting components, which are referred to as vertical limiting components A3 for easy distinction. Each pair of vertical limiting components A3 includes two sets of vertical limiting components A3, that is, the two sets of vertical limiting components A3 are paired, and the two sets of vertical limiting components A3 are arranged longitudinally and facing each other, while each pair of vertical limiting components A3 is arranged sequentially in the transverse direction; the vertical limiting component A3 includes a first mounting base 300 and a vertical rod 301. The first mounting base 300 is adjustable in both the transverse and longitudinal directions on the dispensing platform 1, and the vertical rod 301 is erected on the first mounting base 300.

[0075] The frame limiting mechanism includes at least one pair of vertical limiting components and at least two pairs of transverse limiting components 5 arranged longitudinally. For ease of distinction, these are referred to hereinafter as vertical limiting components B4. Similarly, a pair of vertical limiting components B4 includes two sets of vertical limiting components B4, that is, two sets of vertical limiting components B4 are paired. The two sets of vertical limiting components B4 are arranged longitudinally and facing each other, and are located in the area between the paired vertical limiting components B4 of the beam limiting mechanism. Each pair of vertical limiting components B4 is along... The components are arranged horizontally in sequence; a pair of horizontal limiting components 5 includes two sets of horizontal limiting components 5, that is, two sets of horizontal limiting components 5 are paired, and the paired horizontal limiting components 5 are arranged horizontally and facing each other; the horizontal limiting component 5 includes a second mounting base 500, a crossbar 501 and a driving mechanism 502. The second mounting base 500 is vertically and adjustable in the longitudinal direction at the dispensing table 1. The driving mechanism 502 is located at the second mounting base 500 and is connected to the crossbar 501 to drive the crossbar 501 to move horizontally.

[0076] The automotive radiator frame and front buffer beam separate assembly positioning and adjustment device has an adjustable height support component on its assembly platform 1, which can temporarily support the radiator frame 9, thereby facilitating subsequent position adjustment. The height of the support component is adjustable, so it can be adjusted to match the height of the horizontal bar 501 of the frame limiting mechanism 5. After the radiator frame 9 is placed on the support component, the horizontal bar 501 of the frame limiting mechanism can pass into the radiator frame 9, and the support component performs initial positioning for the vertical movement, longitudinal rotation, and lateral rotation of the radiator frame 9.

[0077] The pair of vertical limiting components A3 of the beam limiting mechanism restrict the placement of the front buffer beam 10 relative to the water tank frame 9. Since the first mounting seat 300 of the vertical limiting component A3 can be adjusted laterally and longitudinally on the assembly platform 1, the position of the first mounting seat 300 in the lateral direction and the position in the longitudinal direction can be adjusted according to the actual required compensation error. The first mounting seat 300 can also restrict the vertical movement of the front buffer beam 10, so that the upright 301 restricts the front buffer beam 10 to a specific position and positions the front buffer beam 10 in six degrees of freedom.

[0078] The pair of vertical limiting components B4 and the pair of horizontal limiting components 5 of the frame limiting mechanism can restrict the placement position of the water tank frame 9. Since the first mounting base 300 of the vertical limiting component B4 can be adjusted horizontally and vertically on the assembly platform 1, the position of the first mounting base 300 in the horizontal direction and the position in the vertical direction can be adjusted according to the actual error compensation required, thereby restricting the horizontal movement, vertical movement and vertical rotation of the water tank frame 9 by the upright 301. Since the second mounting base 500 of the horizontal limiting component 5 can be adjusted vertically and vertically on the assembly platform 1, the position of the second mounting base 500 in the vertical direction and the position in the vertical direction can be adjusted according to the actual error compensation required. Then, the drive mechanism 502 drives it to penetrate horizontally into the water tank frame 9, restricting the vertical movement, horizontal rotation and vertical rotation of the water tank frame 9, so as to jointly restrict the water tank frame 9 at a certain specific position.

[0079] Therefore, the automotive radiator frame and front buffer beam separate assembly positioning adjustment device can quickly adjust the relative position of the radiator frame 9 and the front buffer beam 10 according to the matching dimensions of the front body and the assembly parts, thereby compensating for the accumulated and transmitted errors during the assembly of the front of the car and improving the matching quality of the front bumper assembly and headlight assembly with the matching parts.

[0080] In some embodiments, the beam limiting mechanism may be provided with two pairs of vertical limiting components A3, which are arranged in a transverse direction to stably support the front buffer beam 10 and prevent tilting.

[0081] Please see Figure 1(In the figure, X represents the horizontal direction, Y represents the vertical direction, and Z represents the vertical direction.) In some embodiments, the beam limiting mechanism is provided with a pair of vertical limiting components A3, and each side of the vertical limiting component A3 of the beam limiting mechanism is provided with an auxiliary positioning seat 8. The auxiliary positioning seat 8 is located on the side of the vertical limiting component A3 of the beam limiting mechanism facing the horizontal direction, so as to support the front buffer beam 10 together with the first mounting seat 300 of the vertical limiting component A3, thereby stably supporting the front buffer beam 10 and avoiding tilting.

[0082] Please see Figure 2 In some embodiments, the support assembly includes a support base 2, which includes a base body 200 and several gaskets 6. The gaskets 6 are stacked on top of the base body 200 and vertically locked to the assembly table 1 by bolts. The number of stacked gaskets 6 is selected to adjust the height of the support base 2, and the height of the support base 2 is adjusted more precisely in this way.

[0083] In some embodiments, the support 2 is provided in four sets, and the four sets of support 2 respectively support the four corners of the water tank frame 9.

[0084] Please see Figure 1 and Figure 3 In some embodiments, the first mounting base 300 is mounted on the assembly table 1 via a first adjustment structure. The first adjustment structure includes a first fixed base 302, a first intermediate base 303, and several gaskets 6. The first fixed base 302 is fixedly mounted on the assembly table 1. The first intermediate base 303 includes a first vertical surface 3030 facing the longitudinal direction and a second vertical surface 3031 facing the transverse direction. Some gaskets 6 are stacked between the first fixed base 302 and the first vertical surface 3030 of the first intermediate base 303, and are longitudinally locked by bolts 7. The number of stacked gaskets 6 is selected to adjust the longitudinal position of the first mounting base 300. Some gaskets 6 are stacked between the second vertical surface 3031 of the first intermediate base 303 and the first mounting base 300, and are transversely locked by bolts 7. The number of stacked gaskets 6 is selected to adjust the transverse position of the first mounting base 300. Thus, by adding or removing gaskets 6, the transverse and longitudinal positions of the first mounting base 300 can be adjusted, and the adjustment of the first mounting base 300 in this way is more precise.

[0085] Please see Figure 1 and Figure 4In some embodiments, the second mounting base 500 is mounted on the assembly table 1 via a second adjustment structure. The second adjustment structure includes a second fixed base 503, a second intermediate base 504, and several gaskets 6. The second fixed base 503 is fixedly mounted on the assembly table 1. The second intermediate base 504 includes a third vertical surface 505 facing the longitudinal direction and a horizontal surface 506 facing upwards. Some of the gaskets 6 are stacked between the second fixed base 503 and the third vertical surface 505 of the second intermediate base 504 and are longitudinally locked by bolts 7. The number of stacked gaskets 6 is selected to adjust the longitudinal position of the second mounting base 500. Some of the gaskets 6 are stacked between the horizontal surface 506 of the second intermediate base 504 and the second mounting base 500 and are vertically locked by bolts 7. The number of stacked gaskets 6 is selected to adjust the vertical position of the second mounting base 500. By adding or removing gaskets 6, the vertical and longitudinal positions of the second mounting base 500 can be adjusted, and the adjustment of the second mounting base 500 in this way is more precise.

[0086] In some embodiments, the gaskets 6 include gaskets 6 of various thicknesses, including 2mm, 1mm, 0.5mm, 0.2mm, and 0.1mm. The gaskets 6 are available in various specifications to ensure accurate positioning of the water tank frame 9.

[0087] In actual use, it is necessary to compensate for errors according to actual needs and pre-adjust the height of the supporting components, the position of the first mounting base 300 of the frame limiting mechanism in the horizontal and vertical directions, the position of the second mounting base 500 of the frame limiting mechanism in the vertical and longitudinal directions, and the position of the first mounting base 300 of the beam limiting mechanism in the horizontal and vertical directions. Please refer to [the relevant documentation]. Figure 5 (In the diagram, X represents the horizontal direction, Y the vertical direction, and Z the vertical direction.) Next, place the water tank frame 9 on the supporting assembly, and ensure that the upright 301 of the vertical limiting assembly B4 of the frame limiting mechanism passes through the water tank frame 9. Then, activate the drive mechanism 502, which extends the horizontal bar 501 of the horizontal limiting assembly 5 of the frame limiting mechanism until it passes through the water tank frame 9. Please refer to [link / reference]. Figure 6 (In the figure, X is horizontal, Y is vertical, and Z is vertical.) Next, the front buffer beam 10 is placed longitudinally across the water tank frame 9, and the upright 301 of the vertical limiting component A3 of the beam limiting mechanism passes through the front buffer beam 10. At this time, the positioning of the water tank frame 9 and the front buffer beam 10 is completed. The relative position of the water tank frame 9 and the front buffer beam 10 can be fixed by bolts. This relative position can compensate for the accumulated and transmitted errors during the assembly of the front of the car, and improve the matching quality of the front bumper assembly and the headlight assembly with the matching parts.

[0088] The horizontal bar 501 and vertical bar 301 of the frame limiting mechanism both pass through the holes located at the water tank frame 9. Since the paired vertical limiting components B4 of the frame limiting mechanism need to be adjusted longitudinally, and the paired horizontal limiting components 5 of the frame limiting mechanism also need to be adjusted longitudinally, please refer to [the relevant documentation / reference needed]. Figure 7 In some embodiments, the water tank frame 9 is provided with at least one first set of vertical holes and a pair of horizontal holes. The pair of horizontal holes includes two sets of horizontal holes. The first set of vertical holes is located on the top surface of the water tank frame 9 and includes a first circular vertical hole 900 and a first allowance vertical hole 901, so that the pair of vertical limiting components B4 of the frame limiting mechanism can pass through one by one. The first allowance vertical hole 901 has a margin for the vertical rod 301 to move in the longitudinal direction, that is, the horizontal cross section is a longitudinal strip shape. After adjusting the longitudinal position of the vertical limiting component B4, it can be ensured that the pair of vertical limiting components B4 can pass through the first circular vertical hole 900 and the first allowance vertical hole 901 one by one.

[0089] The transverse hole group includes transverse holes 902 arranged longitudinally and at least one spare transverse hole 903. Two pairs of transverse hole groups are respectively located on both sides of the water tank frame 9. One side of the water tank frame 9 has one pair of transverse hole groups (transverse holes 902 and at least one spare transverse hole 903), and the other side of the water tank frame 9 also has one pair of transverse hole groups (transverse holes 902 and at least one spare transverse hole 903). The transverse holes 902 of the paired transverse hole groups allow one pair of transverse limiting components 5 of the frame limiting mechanism to pass through one-to-one. The spare transverse holes 903 of the paired transverse hole groups allow the remaining pairs of transverse limiting components 5 of the frame limiting mechanism to pass through one-to-one. The spare transverse holes 903 all have longitudinal allowance for the movement of the transverse rod 501, meaning their horizontal cross-section is a longitudinally elongated strip. After adjusting the longitudinal position of the transverse limiting components 5, it can be ensured that the vertical limiting components B4 on the same side can pass through the transverse holes 902 and spare transverse holes 903 one-to-one.

[0090] Similarly, please see Figure 8 In some embodiments, the front buffer beam 10 is provided with at least one set of second vertical holes. The second vertical hole set includes a second circular vertical hole 1000 and a second allowance vertical hole 1001 arranged along the longitudinal direction, and are respectively located at both ends of the front buffer beam 10, so that the paired vertical limiting components A3 of the beam limiting mechanism can pass through one by one. The second allowance vertical hole 1001 has a margin for the vertical rod 301 to move in the longitudinal direction, that is, the horizontal cross section is a longitudinal strip shape. After adjusting the longitudinal position of the vertical limiting component A3, it can be ensured that the paired vertical limiting components A3 can pass through the second circular vertical hole 1000 and the second allowance vertical hole 1001 one by one.

[0091] In some embodiments, the drive mechanism 502 is a linear motor, a cylinder, or a hydraulic cylinder, which can enable rapid positioning and disassembly of the water tank frame 9.

[0092] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
