Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile testing fixture, especially to a subframe testing fixture. BACKGROUND

[0002] The chassis performance of the automobile is comfort and controllability, and the two functions are a pair of contradictions. The traditional suspension system can only be adjusted to one side. That is, the suspension system focusing on controllability will inevitably lose some comfort performance, and the suspension focusing on comfort will inevitably affect some controllability. Therefore, designers try to use some complex structures to balance comfort and controllability in the design and matching of the suspension system. Some equipment and design that greatly affect comfort and controllability also emerge as the times require, and the subframe is a typical representative. Tracing the development history of the subframe, we can easily find that, like any other complex technology, the subframe was originally a standard equipment of D-class luxury cars, and has developed to the equipment found in A-class family cars today.

[0003] Simply put, the subframe can be regarded as the skeleton of the front and rear axle. It is a component of the front and rear axle. We know that the traditional load-bearing body without a subframe has a suspension directly connected to the body steel plate. Therefore, the suspension rocker mechanism of the front and rear axle is a scattered part, not an assembly. After the birth of the subframe, the front and rear suspensions can be assembled on the subframe to form an axle assembly, which is then installed on the vehicle body. For today's platform, such design is certainly of great benefit. The complex suspension system is changed from a scattered part to an assembly. The same suspension assembly can be installed on different vehicle bodies. That is, today's suspension design is not like the past, which needs to be developed to match the vehicle body, but can be directly installed as an assembly, and only needs to be slightly adjusted to achieve good matching. This kind of assembly type axle can well reduce the cost and improve the utilization rate of technology.

[0004] In order for the subframe to be completely matched and connected with the vehicle body, the quality control of such body functional parts needs to be highlighted, and the testing fixture has great significance for the subframe product in the automobile product. It can position the product according to the body mounting point, and then check the mounting position of the body accessories, such as the stabilizer bar mounting hole and surface, the steering machine mounting hole and surface, the front / rear swing arm mounting hole and surface, and other important positions. The current subframe testing fixture is set through the through hole on the support according to the original design requirements of the subframe, then the prepared subframe is placed on the support, and the detection pin is inserted into the opening of the subframe, and the position degree of the hole is judged by observing whether the detection pin passes through the opening of the subframe and the through hole on the support at the same time. This detection method cannot detect the degree of hole offset.

[0005] The prior art discloses a kind of automobile front subframe assembly testing fixture (CN210141826U), including left front support, right front support, left rear support, right rear support, left pressing tool and right pressing tool, left front support includes first positioning column that can be matched with front subframe first installation hole gap, right front support includes second positioning column that can be matched with front subframe second installation hole gap, left rear support includes third positioning column that can be matched with front subframe third installation hole gap, right rear support includes fourth positioning column that can be matched with front subframe fourth installation hole gap, left pressing tool is adapted to the left side beam of front subframe and is used to fix the left side beam, right pressing tool is adapted to the right side beam of front subframe and is used to fix the right side beam, first positioning assembly, second positioning assembly, left pressing tool and right pressing tool are all equipped with multiple spring positioning pins.The patent is placed on left front support, right front support, left rear support, right rear support by front subframe, then third positioning column, fourth positioning column are inserted into first installation hole, second installation hole respectively, check whether third positioning column can be inserted into first shaft hole, fourth positioning column whether can be inserted into second shaft hole.Therefore, the patent can only detect whether positioning column can pass through the through hole of front subframe and the shaft hole on support simultaneously, to detect whether the hole of front subframe is manufactured accurately, but this detection mode cannot detect the offset degree of hole.

Moreover, the hole position detection device 300 of the embodiment further comprises a passing detection pin 380. When the movable block 340 is fixed, the passing detection pin 380 is inserted into the opening of the sub-frame 700, and whether the passing detection pin 380 extends from the lower side of the movable block 340 is observed, so as to detect the passing property of the opening of the sub-frame 700, that is, whether the opening of the sub-frame 700 is through. Since the first detection hole 341 of the movable block 340 is located at the accurate position required by the design of the sub-frame 700, whether the opening of the sub-frame 700 is within a reasonable range and whether the opening of the sub-frame 700 can still be connected by a bolt or the like can be detected by observing whether the passing detection pin 380 extends from the lower side of the movable block 340.

[0046] Embodiment Two

[0047] The difference between the embodiment and the embodiment one is that the auxiliary frame 700 gauge of the embodiment further comprises a relative position detection device 400.

[0048] In the embodiment, the auxiliary frame 700 gauge further comprises a relative position detection device 400, the relative position detection device 400 comprises a handheld rod 410 and a relative position detection pin 420, the two ends of the handheld rod 410 are provided with a second detection hole 411 through which the relative position detection pin 420 passes. The auxiliary frame 700 has left and right two longitudinal beams which are left-right symmetrical structures. When the auxiliary frame 700 is installed, the length of a vehicle part connected with the auxiliary frame 700 is certain, such as a stabilizer bar, a steering machine, etc. The vehicle part needs to be connected with the left and right two longitudinal beams of the auxiliary frame 700, so it is necessary to detect the relative position between the holes on the left and right two longitudinal beams. Therefore, according to the distance between the originally designed positions of the corresponding holes on the two longitudinal beams, the embodiment selects a handheld rod 410 with a corresponding length, places the handheld rod 410 above the auxiliary frame 700, passes the first relative position detection pin 420 through the second detection hole 411 at one end of the handheld rod 410 and inserts it into the hole of one of the longitudinal beams, and then passes the second relative position detection pin 420 through the second detection hole 411 at the other end of the handheld rod 410. Whether the second relative position detection pin 420 can pass through the second detection hole 411 at the other end of the handheld rod 410 and be inserted into the hole of the other longitudinal beam is used to judge whether the relative position of the holes on the two longitudinal beams meets the requirements.

[0049] Further, the handheld rod 410 of the embodiment is a telescopic rod, and the length of the handheld rod 410 can be adjusted according to the distance between the originally designed positions of the two holes, so that only one handheld rod 410 can meet the relative position measurement requirements of all pairs of holes, thereby reducing the cost and being convenient and efficient to use.

[0050] The other structure of the embodiment is the same as that of Embodiment One, which will not be repeated here.

[0051] Embodiment Three

[0052] The difference between the present embodiment and Embodiment Two is that the sub-frame 700 gauge of the present embodiment further comprises an absolute position detection device 500.

[0053] In the present embodiment, the sub-frame 700 gauge further comprises an absolute position detection device 500, the absolute position detection device 500 comprises an absolute position detection pin 510, the support device 200 comprises a plurality of support blocks 350210 and a bracket 220, the bracket 220 is detachably connected to the rack 100, one end of the support block 350210 is connected to the bracket 220, the other end of the support block 350210 is provided with a through hole 211 corresponding to the opening position of the sub-frame 700 to be detected, and the through hole 211 is used for the absolute position detection pin 510 to pass through. The support block 350210 is connected with the rack 100 through the bracket 220, and the support block 350210 is suspended. When installing the bracket 220 and the support block 350210, the through hole 211 on the support block 350210 is positioned at the originally designed (theoretically designed) position of the sub-frame 700 according to the originally designed (theoretically designed) requirement of the sub-frame 700. When detecting, the sub-frame 700 is placed on the support block 350210, and the absolute position detection pin 510 is inserted into the opening of the sub-frame 700. Whether the absolute position detection pin 510 can pass through the through hole 211 of the support block 350210 below is used to determine whether the opening of the sub-frame 700 is at the theoretically designed position. The sub-frame 700 can be positioned and fixed on the support device 200 by the absolute position detection pin 510 passing through the opening of the sub-frame 700 and the through hole 211 on the support block 350210.

[0054] Further, the absolute position detection pin 510 of the present embodiment comprises a pin body 511 and a blocking piece 512, the blocking piece 512 is connected to the pin body 511 and can move along the axial direction of the pin body 511, and the blocking piece 512 is an elastic body. The longitudinal beam and the cross beam of the sub-frame 700 are both hollow shells. Some openings only pass through one layer of plate, and some openings need to pass through two layers of plate. The position of the blocking piece 512 on the pin body 511 is adjusted according to the distance between the two openings passing through two layers of plate, and then the absolute position detection pin 510 is inserted into the opening of the sub-frame 700. Since the upper layer of plate is manually operated to be pressed, the blocking piece 512 passes through the opening of the upper layer of plate together with the pin body 511, and then the blocking piece 512 restores. When passing through the lower layer of plate, the blocking piece 512 abuts against the lower layer of plate, so that whether the top end of the pin body 511 is higher than the upper layer of plate and whether the bottom end of the pin body 511 protrudes from the opening of the lower layer of plate can be observed to determine the up-down position and passability of the two holes.

[0055] In addition, the testing tool of the embodiment further comprises a pin rack 600 installed on the rack 100, and the pin rack 600 is provided with a placing hole for detecting the insertion of the pin. The pin rack 600 facilitates the placement of the offset detection pin 310, the pass-through detection pin 380, the relative position detection pin 420 and the absolute position detection pin 510, is conducive to the neatness of the testing tool, and can prevent the loss of each detection pin.
