Description

Technical Field

[0001] This utility model relates to the field of automotive welding bracket assembly technology, and in particular to a universal support device for welding bracket assembly. Background Technology

[0002] In the automotive manufacturing industry, welding brackets are the core tooling for chassis assembly, and their assembly precision directly affects the welding quality of the chassis. Currently, fixed support platforms are commonly used, which are generally made of channel steel and rectangular steel welded into a rigid frame, and are only suitable for a single type of welding bracket. Different specifications of brackets require dedicated support platforms. Therefore, existing automotive welding positioning bracket assembly workshops need to use multiple support platforms of different models when producing and assembling different types of brackets, resulting in a large amount of equipment piling up in the workshop.

[0003] To address this, we designed a universal support device for assembling welding brackets. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model discloses a general-purpose support device for assembling welding brackets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A general-purpose support device for assembling welding brackets, comprising: Base plate; A longitudinal slide rail pair is provided on the upper surface of the base plate; A transverse slide rail pair is provided on the upper surface of the base plate and located on both sides of the longitudinal slide rail pair; A side positioning unit is disposed above the sliding part of the transverse slide rail pair. The side positioning unit includes a longitudinal support beam, multiple height-adjustable support units, and a positioning magnetic side plate. The multiple support units are spaced apart along the length direction of the longitudinal support beam, and the positioning magnetic side plate is disposed on the outside of the longitudinal support beam for supporting and positioning the side of the welding bracket. A central positioning unit is disposed above the sliding part of the longitudinal slide rail pair. The longitudinal slide rail pair has multiple sliding parts, and the central positioning unit is disposed above each sliding part. The central positioning unit includes a transverse support beam and two height-adjustable support units, which are respectively disposed at both ends of the transverse support beam.

[0006] Furthermore, each side of the base plate is provided with at least two of the transverse slide rail pairs, and the side positioning unit is supported by at least two of the transverse slide rail pairs on the same side.

[0007] Furthermore, the sliding part is screwed with a locking bolt to lock the position of the sliding part on the corresponding slide rail.

[0008] Furthermore, the support unit includes: An adjusting rod, the height of which is adjustable, is connected to the corresponding longitudinal or transverse support beam; The support rod has its middle part connected to the upper end of the adjusting rod, and its two ends have upwardly extending support parts.

[0009] Furthermore, the support rod is a U-shaped, V-shaped, or C-shaped structure with the opening facing upwards.

[0010] Furthermore, the support portion is rotatably connected to a support wheel.

[0011] Furthermore, the adjusting rod includes: A vertical sliding column is vertically slidably connected to a corresponding support beam, and a threaded hole is provided on the bottom surface of the vertical sliding column; The adjusting screw has its lower end rotatably connected to the corresponding support beam, and its upper end screwed into the threaded hole of the vertical sliding column; Rotate the handle, which is located at the lower end of the adjusting screw.

[0012] Furthermore, the vertical sliding column is provided with scale markings.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. Through the multi-directional adjustable design of longitudinal and transverse slide rail pairs, combined with the layout of side positioning units and central positioning units, the welding bracket can achieve three-dimensional precise positioning in the transverse, longitudinal and height directions, so as to adapt to different sizes and models of automotive welding brackets and solve the drawback of traditional support platforms that are "one machine for one use". 2. The positioning magnetic side plate directly adsorbs onto the side wall of the welding bracket, and together with the support unit, it supports the bottom surface, forming a two-way constraint, eliminating the need for mechanical clamping and simplifying the operation; 3. Through the rotational installation of the support rod and the design of the support wheel, it can better adapt to situations where the bottom surface of the welding bracket has large roughness or is sloping, thereby further improving the stability of the welding bracket.

[0016] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if terms such as "upper", "lower", "front", "rear", "left", "right" indicate orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention. It should be understood that if terms such as "end", "side", "end portion", "side part", "lateral", "longitudinal", etc. indicate orientation or positional relationship, they are only corresponding to the length and width of the corresponding component. That is, "end" indicates the head and tail area in the length direction of the corresponding component, and "side part" indicates the head and tail area in the width direction of the corresponding component. They are used for the convenience of describing the present invention and do not indicate or imply that the device or element referred to must have a specific orientation.

[0017] Example 1, in conjunction with Appendix Figure 1-3 A general-purpose support device for assembling welding brackets, comprising: Base plate 1; The longitudinal slide rail pair 2 is located on the upper surface of the base plate 1. Specifically, the longitudinal slide rail pair 2 is located at the middle position in the width direction of the base plate 1. The longitudinal slide rail pair 2 has multiple sliding parts, that is, multiple sliding parts are slidably connected on the longitudinal slide rail of the longitudinal slide rail pair 2; the number of sliding parts is set according to the number of crossbars of the welding bracket, and is not specifically limited here.

[0018] The transverse slide rail pair 3 is located on the upper surface of the base plate 1 and on both sides of the longitudinal slide rail pair 2. That is to say, there are two sets of transverse slide rail pairs 3, located on both sides of the longitudinal slide rail pair 2.

[0019] Furthermore, the sliding part is screwed with a locking bolt 8 to lock the position of the sliding part on the corresponding slide rail; that is, each sliding part of the longitudinal slide rail pair 2 is screwed with a locking bolt 8 to lock the position of the sliding part on the longitudinal slide rail; the sliding part of the transverse slide rail pair 3 is also screwed with a locking bolt 8 to lock the position of the sliding part on the transverse slide rail. Furthermore, due to the relatively large length of the side positioning unit, to ensure its stability, each set of transverse slide rail pairs 3 has at least two components, and the side positioning unit is supported by at least two transverse slide rail pairs 3 on the same side. Preferably, the number of transverse slide rail pairs 3 in each set is 2-4.

[0020] The side positioning unit is located above the sliding part of the transverse slide rail pair 3. The side positioning unit includes a longitudinal support beam 4, multiple height-adjustable support units 5, and a positioning magnetic side plate 6. The multiple support units 5 are spaced apart along the length of the longitudinal support beam 4, and the positioning magnetic side plate 6 is located on the outer side of the longitudinal support beam 4. In this way, the side of the welding bracket can be attracted and fixed by the positioning magnetic side plate 6, and the bottom surface of the side beam can be supported by the multiple support units 5 to ensure the stability of the side beam position.

[0021] In one possible implementation, the positioning magnetic side plate 6 is composed of a magnetic plate and an electromagnet located outside the magnetic plate.

[0022] Multiple central positioning units are respectively located above each sliding part of the longitudinal slide rail pair 2. The central positioning unit includes a transverse support beam 7 and two height-adjustable support units 5, which are respectively located at both ends of the transverse support beam 7.

[0023] Furthermore, the support unit 5 includes an adjusting rod 51 and a support rod 52 located at the upper end of the adjusting rod 51. The support rod 52 is connected to the upper end of the adjusting rod 51 in the middle and has upwardly extending support portions 521 at both ends; for example, the support rod 52 is a U-shaped, V-shaped, or C-shaped structure with an upward opening. This allows the workpiece bottom surface to be adapted to the same height by changing the height of the two support portions 521.

[0024] It should be noted that the support rod 52 in the support unit 5 on the side positioning unit is arranged longitudinally, while the support rod 52 in the support unit 5 on the middle positioning unit is arranged transversely.

[0025] In one possible implementation, the adjusting rod 51 includes a vertical sliding column 511 vertically slidably connected to the corresponding support beam, with a threaded hole on the bottom surface of the vertical sliding column 511; an adjusting screw 512 rotatably connected to the corresponding support beam at its lower end, with the upper end of the adjusting screw 512 screwed into the threaded hole of the vertical sliding column 511; wherein, a rotating handle 513 is provided at the lower end of the adjusting screw 512; that is, by rotating the handle 513, the adjusting screw 512 is driven to rotate, and under the action of the threaded engagement, the vertical sliding column 511 is driven to rise or fall, thereby driving the support rod 52 to rise or fall.

[0026] Specifically, the vertical sliding column 511 has a non-circular cross-section, meaning that the vertical sliding column 511 can only rise or fall relative to the supporting beam and cannot rotate.

[0027] Furthermore, the vertical sliding column 511 has scale markings on its shaft.

[0028] In other embodiments, the adjusting rod 51 may also be an automatically adjusting device such as a cylinder.

[0029] Working principle: First, adjust the spacing between the two side positioning units and the position of the middle positioning unit according to the size of the automotive welding bracket. Then, place each component of the automotive welding bracket on the support device. Next, drive the adjusting screw 512 by rotating the handle 513 to raise the support wheel 53 and lift the bracket to the predetermined height. At this point, welding or bolting operations can be performed on each component.

[0030] Locking: Tighten all locking bolts 8 to fix the position of the side positioning unit. Adjustment: Push the side positioning unit along the slide rail of the transverse slide rail pair 3. After it is in place, fix the position of the side positioning unit by locking bolts 8.

[0031] Position adjustment of the central positioning unit: Push the central positioning unit along the slide rail of the longitudinal slide rail pair 2, and fix the position of the central positioning unit by locking bolt 8 after it is in place.

[0032] Example 2, in conjunction with Appendix Figure 3 A general-purpose welding bracket assembly support device, which differs from Embodiment 1 in that the support rod 52 is optimized and the support part 521 is rotatably connected to the support wheel 53.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the above embodiments should be regarded as exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended to include all changes that fall within the meaning and scope of the equivalents of the claims in this utility model, and no reference numerals in the claims should be regarded as limiting the content of the claims.
