[0002] The vehicle skeleton, or frame, is a frame-like structure that spans the front and rear axles of the car and is the base of the vehicle. The frame must have sufficient strength and rigidity to withstand the load of the car and the impact from the wheels. The function of the frame is to support and connect the various assemblies of the car, so that each assembly maintains a relatively correct position and withstands various loads inside and outside the car. The frame needs to undergo various processing before it is assembled, including parts processing, frame welding, steel pipe bending, etc. During these processing processes, the processes used are also different, so different tooling will be used for processing. In order to meet production requirements, these processing tools also need to be processed into specific styles. In order to ensure the accuracy of the processing tools, they need to be positioned during processing.

[0003] Existing tooling used for positioning can often only position one or several types of processing tooling. Since there are many ways to process vehicles, there are also many types of corresponding processing tooling. When positioning different processing tooling, the positioning tooling needs to be replaced frequently, otherwise it may result in poor positioning accuracy or even inability to position, making the process of positioning the processing tooling more troublesome.

[0013] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0014] according to Figure 1-2 The utility model provides an adjustable positioning tool, comprising: a base plate 1, a positioning plate 2, a fixing column 3, and a fixing screw 4.

[0015] The fixing column 3 is arranged in the middle of the four sides of the bottom plate 1. The positioning plate 2 is composed of two swinging plates 21. One of the swinging plates 21 is rotatably mounted on one of the fixing columns 3, and the other swinging plate 21 is rotatably mounted on the adjacent fixing column 3. The two swinging plates 21 are always kept in contact with each other. The number of positioning plates 2 is several. The fixing screw 4 can fix the two swinging plates 21. The swinging plate 21 includes: a rotating hole 211 and a sliding groove 212. The rotating hole 211 corresponds to the fixing column 3. The sliding groove 212 is opened on the side of the swinging plate 21 away from the rotating hole 211. The sliding groove 212 corresponds to the fixing screw 4. The fixing screw 4 includes: a screw 41 and a nut 42. The larger end of the screw 41 is a screw head 411. The tip of the screw 41 passes through the contact point of the two swinging plates 21 in contact. The screw 41 passes through the sliding groove 212. The screw 41 can slide in the sliding groove 212. The nut 42 is sleeved on an end of the screw 41 away from the screw head 411 .

[0016] When assembling the tooling, one side of the fixed column 3 needs to be fixed on the bottom plate 1. During assembly, the two swing plates 21 of the positioning plate 2 are respectively mounted on the two fixed columns 3, and then the two swing plates 21 are rotated so that the two swing plates 21 are staggered and in contact, and their sliding grooves 212 are respectively overlapped with each other at one end away from the fixed column 3 on which they are mounted (for convenience of explanation, this end is referred to as the limit end below), and at this time, the screw 41 of the fixing screw 4 can pass through the overlapped part, and the passing direction of the screw 41 is from the side where the fixed column 3 is to be set on the bottom plate 1 to the other side of the fixed column 3, and then the nut 42 is screwed in from the tip of the screw 41 so that the screw 41 will not fall off from the sliding groove 212. According to this method, the positioning plate 2 is set on the four fixed columns 3, and then the four fixed columns 3 are respectively set at the middle positions of the four sides of the bottom plate. At this time, one end of the swing plate 21 is rotatably arranged on the fixed column 3, and the other end is in contact with the other swing plate 21. Since the fixing screw 4 passes through their overlap, the two swing plates 21 always keep in contact, that is, they always have an overlap on the sliding groove 212. When it is necessary to fix the two swing plates 21, press the screw head 411 of the screw 41 and tighten the nut 42 so that the screw head 411 and the nut 42 clamp the two swing plates 21 at both ends of the overlap, so that they remain fixed. When it is necessary to change the position of the swing plate 21, loosen the nut 42, but keep the nut 42 still on the screw 41, so that the two swing plates 21 can move relative to each other. When one of the swing plates 21 rotates, it will drive the fixing screw 4 to move. Since the fixing screw 4 passes through the sliding grooves 212 of the two swing plates 21, the fixing screw 4 will drive the other swing plate 21 to rotate at the sliding groove 212. During the rotation process, the fixing screw 4 is always at the overlap of the two sliding grooves 212. When it is necessary to tighten the fixing screw 4, it is necessary to press the screw head 411 and rotate the nut 42. Pressing only requires one or more fingers to hold down, and the required space is small, while rotating requires multiple fingers to hold down and then rotate with the palm, which occupies a larger space. In the above method, the passing direction of the fixing screw 4 makes the screw head 411 face the side of the base plate 1, and the nut 42 is away from the side of the base plate 1, so that the nut 42 is not restricted by the base plate 1, ensuring the space required for screwing the nut 42, making it more convenient to control the fixing or loosening of the swing plate 21.

[0017] When it is necessary to position the processing tooling, place the processing tooling on the base plate 1 within the range surrounded by the four fixing columns 3, keep the fixing screws 4 loose, rotate the swing plate 21 to rotate, so that the fixing screws 4 drive the other swing plate 21 to rotate, so that the two swing plates 21 approach the processing tooling and finally conflict with the processing tooling, and then tighten the nuts 42 to fix the two swing plates 21, so that the two swing plates 21 can only rotate in the same way, and the two swing plates 21 are mounted on different fixing columns 3, that is, their rotation axes are different, so the rotation modes of the two swing plates 21 are different, so the two swing plates 21 cannot rotate, so that the positioning plate 2 remains in a fixed state. Since a plurality of positioning plates 2 are arranged on the fixing columns 3, and the fixing columns 3 are arranged on the four sides of the base plate 1, there are a plurality of positioning plates 2 around the processing tooling to conflict with it, and after the swing plates 21 of the positioning plates 2 are fixed, the fixed positioning plates 2 can clamp the processing tooling. In the above method, the swing plate 21 can rotate toward the center of the bottom plate or toward the outside of the bottom plate, and its position can be adjusted according to actual conditions, so that various processing tools can be effectively positioned. When positioning, the utility model can complete the positioning of the processing tool by rotating the swing plate 21 to a certain position and then fixing the two swing plates 21 by fixing screws 4, and the operation is simple.

[0018] A positioning plate 2 is provided on each two adjacent fixing columns 3. The length of the swing plate 21 is smaller than the distance between the connecting lines of the two adjacent fixing columns 3.

[0019] The fixed column 3 is arranged in the middle of the four sides of the bottom plate 1, and a positioning plate 2 is arranged on each two adjacent fixed columns 3, that is, the positioning plates 2 are distributed around the bottom plate 1, so that when the positioning plates 2 position the processing tooling on the bottom plate 1, they can contact the processing tooling around to ensure that the processing tooling can be fixed, and multiple positioning plates 2 are fixed so that the processing tooling can be positioned more firmly. During the rotation of the swing plate 21 around the fixed column 3, when the swing plate 21 rotates to coincide with the line connecting the two adjacent fixed columns 3, the end of the swing plate 21 that is not mounted on the fixed column 3 is closest to the fixed column 3. In order to prevent the swing plate 21 from contacting the fixed column 3, the length of the swing plate 21 needs to be less than the distance between the lines connecting the two adjacent fixed columns 3.

[0020] The working principle and use process of this utility model:

[0021] When it is necessary to position the processing tooling, the processing tooling is placed on the base plate 1 within the range surrounded by the four fixing columns 3. For the same positioning plate 2, the swing plate 21 is moved toward the processing tooling, and the swing plate 21 drives the fixing screw 4 in the sliding groove 212 to move, and the fixing screw 4 then drives another swing plate 21 to move toward the processing tooling, and finally contacts with the processing tooling. Similarly, other positioning plates 2 are contacted with the processing tooling, and then the screw head 411 of each screw 41 is pressed in turn, and the corresponding nut 42 is tightened to fix the two contacting swing plates 21, that is, the positioning plate 2 is positioned. When processing the last positioning plate 2, its swing plate 21 is moved again so that the swing plate 21 conflicts with the processing tooling, and the processing tooling also conflicts with other positioning plates 2, and then the fixing screw 4 is tightened so that when each positioning plate 2 conflicts with the processing tooling, the processing tooling is clamped to complete the positioning.

[0022] In summary, the utility model uses a plurality of movable swing plates to position processing tools of various sizes within a certain range without replacement, and the fixation of the processing tools can be controlled by rotating the swing plates and controlling the fixing screws, which is easy to operate.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
