[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] The utility model provides a transition bracket tooling for a passenger car. Figure 1 A three-dimensional schematic diagram of a transition bracket tooling for a passenger vehicle in an embodiment of the utility model is shown. Figure 1 In the figure, the transition bracket tooling for passenger vehicles includes: a first connecting part 1, a second connecting part 2, and a connecting part 3. A threaded hole 4 for bolt connection with the vehicle frame is provided on the upper end surface of the first connecting part 1, a positioning hole 5 is provided on the lower end surface of the second connecting part 2, and the positioning hole 5 is used to form a aligning connection with the fixed pin head on the slide pin seat, a positioning block 6 is provided on the upper end surface of the second connecting part 2, and the positioning block 6 is used to align and connect with the hole groove provided on the vehicle frame, and the connecting part 3 is used to connect the first connecting part 1 and the second connecting part 2, so that the first connecting part 1, the second connecting part 2, and the connecting part 3 form a whole and can be used as a complete bracket tooling piece.
[0025] It should be noted that, in the actual use of the bracket tooling of the present application, it is first necessary to select bracket tooling of different specifications according to different types of frames and slide production lines; first determine the positioning slots and similar installation slots that have been set at the bottom of the frame, and then determine the length of the connecting portion 3, with the shortest connecting portion 3 being the most preferred, and then determine the position of the positioning block 6 and the positioning hole 5 on the second connecting portion 2 in combination with the pin head position of the slide pin seat to be placed; at the same time, according to the numerical difference between the width of the frame and the width of the slide, select two bracket toolings as needed to be installed at the front and rear ends on the same side of the bottom of the frame, or select four bracket toolings to be installed at the front and rear ends on both sides of the bottom of the frame.
[0026] During the installation process, if Figure 5 As shown, first insert the positioning block 6 provided on the upper end surface of the second connecting part 2 into the corresponding positioning slot hole, rotate the bracket fixture with the positioning slot hole as the center of the circle, so that the threaded hole 4 provided on the upper end surface of the first connecting part 1 forms a coaxial arrangement with the corresponding mounting slot hole on the frame, and use bolts to fix the threaded hole 4 and the mounting slot hole, thereby realizing the relative fixation of the bracket fixture and the frame; after the bracket fixture is installed, the frame can be transferred as a whole to the skid, and the pin head of the skid pin seat can be inserted into the corresponding positioning hole 5 of the bracket fixture, and the entire vehicle body together with the bracket fixture falls on the skid, and the skid can be locked as needed to complete the placement.
[0027] Specifically, the first connecting part 1 adopts a hollow square column structure. On the basis that the hardness of the first connecting part 1 itself meets the maximum bearing force, the hollow design reduces the weight of the first connecting part 1 itself, reduces the consumption of production materials of the first connecting part 1, and at the same time allows the bolts that form a threaded connection with the threaded hole 4 to directly penetrate into the first connecting part 1, without the need to perform deep processing of the thread groove on the first connecting part 1 for the bolts, thereby reducing the processing difficulty and production cost of the first connecting part 1; the first connecting part 1 is arranged vertically, and a notch connecting the inner cavity of the first connecting part 1 is provided on the lower end surface of the first connecting part 1. In actual use, one or more nuts can be added and installed by the bolts entering from the lower end of the first connecting part 1 into the interior of the first connecting part 1, so that the nuts are abutted against the inner wall of the upper end of the first connecting part 1, further increasing the firmness of the connection between the first connecting part 1 and the frame; the first connecting part 1 can also be a cylindrical structure, a polygonal structure, etc., which is not limited in the present application.
[0028] At the same time, on the basis of ensuring the hardness of the first connecting part 1 itself, a notch 7 is opened on the adjacent side wall where the first connecting part 1 is connected to the connecting part 3. Through the notch 7, the penetration length and current status of the internal bolts of the first connecting part 1 can be directly observed from the side, thereby improving the convenience of installing the first connecting part 1 and the frame.
[0029] In addition, reference Figure 2 The first connecting portion 1 adopts a rounded transition at the corner of the side wall, which improves the comfort of the bracket tooling of the present application, and at the same time, the side wall of the first connecting portion 1 is evenly divided into a middle straight surface area and a side curved surface area. Correspondingly, the boundary line between the middle straight surface area and the side curved surface area is set to coincide with the edge line of the notch 7. On the basis of the first connecting portion 1 adopting a hollow square column structure, the straightness of the boundary line between the middle straight surface area and the side curved surface area is ensured, and the boundary line is made to coincide with the edge line of the notch 7, thereby ensuring that the edge line of the notch 7 maintains a straight property. In the process of assembling the first connecting portion 1 and the frame, it can be judged whether the bolts used for installation remain in a straight state by directly referring to the edge line of the notch 7. At the same time, when looking directly at the notch 7 from the side wall of the first connecting portion 1, it can be judged whether the first connecting portion 1 has deformation and distortion by the edge line of the notch 7 and the boundary line between the middle straight surface area and the side curved surface area of the opposite side wall. Figure 2 In the example shown, the notch 7 adopts an inverted U-shaped structure, and the notch 7 is connected to the notch at the lower end of the first connecting portion 1, which further reduces the production and processing cost of the bracket tooling.
[0030] Specifically, the upper end surface of the first connecting part 1 is provided with a washer part 8 coaxially arranged with the threaded hole 4, so as to reduce the connection surface between the first connecting part 1 and the frame. On the basis of satisfying the point fixation between the first connecting part 1 and the frame for condensation, the problem of crowding out between the first connecting part 1 and the protrusion on the frame is avoided as much as possible.
[0031] refer to Figure 2 The second connecting part 2 adopts a flat rectangular tube structure, and the second connecting part 2 is arranged horizontally. On the basis of the rectangular tube structure, the weight of the second connecting part 2 itself is reduced, and the consumption of production materials of the second connecting part 2 is reduced. At the same time, the two ends of the second connecting part 2 are connected. In the process of docking and placing the bracket tooling and the sled pin seat, the depth of the pin head of the sled pin seat inserted into the positioning hole 5 can be directly observed visually, and the inner cavity height of the second connecting part 2 is controlled to be 1.25-1.5 times the height of the pin head on the sled pin seat. By limiting the inner cavity height of the second connecting part 2, the height difference between the bottom surface of the frame and the sled pin seat is limited to avoid the installation shaking between the frame and the sled caused by the excessive height difference, and the area of the upper and lower end surfaces of the second connecting part 2 is ensured on the basis of flatness, ensuring that the second connecting part 2 has sufficient connection surface with the frame and the second connecting part 2 has sufficient connection surface with the sled pin seat.
[0032] In order to improve the convenience of installing the bracket tooling between the slide pin seat, the positioning pin of the slide pin seat is a column structure, such as Figure 3 As shown, the positioning hole 5 opened at the lower end surface of the second connecting portion 2 adopts an oblong structure, and a certain movable space is given to the installation position of the bracket tooling by enlarging the aperture of the positioning hole 5.
[0033] Specifically, refer to Figure 2 and Figure 4 The connecting part 3 adopts a plate structure with a rectangular cross section. The connecting part 3 is arranged upright. One end of the connecting part 3 is vertically connected to the side wall of the first connecting part 1, and the other end of the connecting part 3 is vertically connected to the side wall of the second connecting part 2, thereby improving the bending resistance of the entire bracket tooling. Figure 2 In the example shown, the lower end surface of the connecting portion 3, the lower end surface of the first connecting portion 1, and the lower end surface of the second connecting portion 2 form a coplanar surface, and the upper end surface of the connecting portion 3 and the upper end surface of the second connecting portion 2 form a coplanar surface. According to the structure of the frame, the upper end surface of the first connecting portion 1 is higher than the upper end surface of the second connecting portion 2, and when the upper end surface of the second connecting portion 2 abuts against the frame, the upper end surface of the first connecting portion 1 can also abut against the bottom of the frame.
[0034] In addition, in actual use, a plurality of threaded holes 4 can be opened on the upper end surface of the first connecting portion 1, and the plurality of threaded holes 4 can be arranged in an array with equal spacing along the extension direction of the connecting portion 3. By changing the position of the threaded holes 4 along the extension direction of the connecting portion 3, the installation position of the bracket tooling and the frame and the installation position of the bracket tooling and the slide pin seat can be adjusted, thereby improving the flexibility of the bracket tooling in use, and can be adapted for use with different frames and slides within a certain range.
[0035] The support fixture of the present application has a simple structure, and there is no need to change the body design or modify the slide. By opening a threaded hole 4 at one end of the support fixture and setting a positioning block 6 and a positioning hole 5 at the other end of the support fixture, one end of the support fixture is fixedly installed at the position of the frame mounting hole, so that the support fixture and the frame temporarily form a whole, so that the other end of the support fixture can be directly adapted and installed on the slide pin seat to form a stable placement, so that the slide / hanger fulcrum of the welding / painting / assembly mechanized conveying equipment to be transferred to the factory is adapted to the vehicle model to be transferred, and the operation is simple. It saves workers' operating hours and greatly increases the vehicle model's passability on the new production line. There is no need to adjust the skid, which meets the needs of co-production of multiple models with a single skid. In addition, the bracket tooling of the present application has a simple structure, low cost, short production cycle, small height, and light weight, which can well meet the needs of the factory. After the conversion or OEM is completed, it can be directly disassembled from the frame and can be used on the next batch of frames of the same specification, meeting the needs of repeated and flexible use. There is no need to consider the possible damage to the vehicle body strength, corrosion resistance and other factors, which solves the problems of tooling production cost and long cycle.
[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
