Description

Technical Field

[0001] The utility model relates to the field of vehicle frame detection, in particular to a device for detecting the verticality of a sub-frame. Background Art

[0002] Verticality detection is a common detection content in chassis component size detection. Taking the front subframe in chassis components as an example, the common verticality detection points include at least the front body mounting point, the middle body mounting point, and the rear body mounting point, which add up to a total of 6 points. If the corresponding verticality detection mechanism is streamlined and reduced in cost, it can bring considerable economic benefits to the enterprise.

[0003] Figure 1 It is a structural schematic diagram of a front subframe in the prior art.

[0004] like Figure 1 As shown, the common front subframe will use four small surfaces A1, A2, A3, and A4 for A-surface positioning. It is necessary to detect the verticality of the front / middle / rear body mounting points to the reference A.

[0005] Common annotation forms are as follows:

[0006] At present, when verticality detection is required, a bidirectional sliding mechanism needs to be configured so that only the A reference plane constraint is retained during detection, and then the detection is performed with the verticality detection pin.

[0007] Figure 2 This is a front view of a verticality detection pin in the prior art. Figure 3 It is a top view of a verticality detection pin in the prior art.

[0008] like Figure 2 and Figure 3 As shown, the mechanism consists of a base 10, a bidirectional sliding mechanism 20, a guide column 30 and a verticality detection pin 50. The guide column 30 is located on the bidirectional sliding mechanism 20, and the sliding mechanism 20 is located on the base 10. After the front section of the detection pin 50 enters the guide column 30, observe whether the rear section of the pin can be inserted into the casing to be inspected, so as to judge whether the inspection result is qualified.

[0009] When the detection pin 50 can be inserted into the tested casing 60 in the active state of the bidirectional slidable mechanism 20, the verticality detection result at that location is qualified. When the pin cannot be inserted into the tested casing 60 in the bidirectional slidable state, the verticality detection result at that location is unqualified. The mechanism is relatively complex and the overall cost is high.

[0010] In view of this, the inventor of the present application has designed a subframe verticality detection device in order to overcome the above technical problems. Utility Model Content

[0014] The other end of the verticality detection pin is a detection section, which is used to insert into the casing to be detected;

[0015] When the guide section and the detection section can be inserted into the guide column and the inspected casing respectively, the verticality detection result is qualified; when the detection section cannot be inserted into the inspected casing, the verticality detection result is unqualified.

[0016] According to an embodiment of the utility model, the guide section is a pin shaft.

[0041] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.Preferred embodiments of the present invention will now be described in detail, examples of which are shown in the accompanying drawings.Where possible, the same reference numerals will be used throughout the drawings to represent the same or similar parts.

[0042] In addition, although the terms used in the present invention are selected from well-known and commonly used terms, some terms mentioned in the specification of the present invention may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description of this article.

[0043] Furthermore, it is required that the present invention be understood not only by the actual terms used but also by the meanings contained in each term.

[0044] Figure 4 It is a structural schematic diagram of the auxiliary frame verticality detection device of the utility model.

[0045] like Figure 4 As shown, the utility model discloses a subframe verticality detection device, which includes a guide column 100 and a verticality detection pin 200, one end of the verticality detection pin 200 is a guide section, the guide section is inserted into the guide column 100, and the verticality detection pin 200 and the guide column 100 are connected in a movable plug-in manner.

[0046] In the detection state, the verticality detection pin 200 is inserted into the guide column 100, and in the non-detection state, the verticality detection pin 200 can be pulled out from the guide column 100. The other end of the verticality detection pin 200 is a detection section for inserting the casing 300 to be detected.

[0047] When the guide section and the detection section can be inserted into the guide column 100 and the casing 300 to be inspected respectively, the verticality detection result is qualified. When the detection section cannot be inserted into the casing 300 to be inspected, the verticality detection result is unqualified.

[0048] Preferably, in this embodiment, the guide section is a pin shaft 210 , and the detection section is a pin sleeve 220 .

[0049] The pin shaft 210 and the pin sleeve 220 are preferably connected to each other in a translational manner.

[0050] In the verticality detection device: the verticality detection pin 200 is composed of a pin shaft 210 and a pin sleeve 220, the pin shaft 210 is used for guiding, and the pin sleeve 220 is used for detection. The pin shaft 210 and the pin sleeve 220 can move smoothly, and the matching surfaces of the two should be finely ground.

[0051] When the guide section (pin shaft 210) and the detection section (pin sleeve 220) can enter the guide column 100 and the sleeve 300 to be inspected respectively, it means that the verticality detection result is qualified. If the detection section (pin sleeve 220) cannot enter the sleeve 300 to be inspected, it means that the verticality detection result is unqualified.

[0052] Furthermore, there is a gap H between the pin shaft 210 and the pin sleeve 200. Taking the aforementioned sub-frame body mounting sleeve as an example, the gap H may preferably be 3 mm to 4 mm.

[0053] In order to make the verticality detection mechanism reliable and easy to use, the gap between the pin shaft and the pin sleeve must be properly considered, and the machining accuracy of the translational surface between the pin shaft and the pin sleeve must be guaranteed. Good machining accuracy should ensure that the pin sleeve and the pin shaft can move flexibly and smoothly at any time.

[0054] Preferably, the diameter of the verticality detection pin 200 is equal to the diameter of the tested casing 300 minus the verticality tolerance. In other words, the size of the verticality detection pin 200 is equal to the maximum physical size of the tested hole diameter of the tested casing 300 minus the verticality tolerance. For example, taking the aforementioned verticality tolerance of 0.5 as an example, 0.5 is subtracted.

[0055] In addition, a guide hole is provided in the guide column 100 so that the guide section and the guide hole match each other.

[0056] According to the above structural description, the structure of the sub-frame verticality detection device of the utility model is very simple, including a guide column 100 and a verticality detection pin 200. Among them, the structure of the guide column 100 already exists in the existing verticality detection mechanism, and the existing verticality detection mechanism is to superimpose the guide column on the bidirectional sliding mechanism. However, the sub-frame verticality detection device described in the present application only needs a separate guide column 100, and does not need a bidirectional sliding mechanism.

[0057] The improved verticality detection pin 200 is different from the verticality detection pin on the existing detection mechanism in that the detection pin has a pin sleeve 220 that can move in translation in addition to the pin shaft 210 .

[0058] When testing the verticality of the subframe sleeve, after positioning the front subframe on the inspection fixture, use the verticality inspection pin 200 to insert the subframe sleeve 300 to be inspected, and the pin shaft 210 at the front end of the verticality inspection pin 200 first passes through the subframe sleeve 300 to be inspected and enters the guide column. While the pin shaft 210 is inserted downward into the guide column 100, observe whether the translation pin sleeve at the rear end of the inspection pin can pass through the sleeve to be inspected, so as to judge whether the verticality of the subframe sleeve to be inspected meets the requirements. It is easy to use and has a simple structure.

[0059] In summary, the subframe verticality detection device of the utility model greatly simplifies the complexity of the verticality detection structure and is easy to use.

[0060] The mechanism is reliable and easy to use, and can ensure the machining accuracy of the translational surface between the pin shaft and the pin sleeve. Good machining accuracy can ensure that the pin sleeve and the pin shaft can perform flexible and smooth translation at any time.
