[0002] The engine hanger bracket is stamped by a hanger bracket fixture. Since the outer edge of the engine hanger bracket is composed of multiple arc segments, the inner wall of the hanger bracket fixture is also a curved surface composed of multiple arc segments. Since the inner cavity wall of the hanger bracket fixture is non-planar, it is difficult to use a mechanical structure for inspection. Therefore, this application invents a testing mechanism for mechanically inspecting the inner cavity wall of the hanger bracket fixture. Utility Model Content

[0003] In view of the problems existing in the current automotive parts stamping fixture testing mechanism, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide an inspection mechanism for stamping fixtures of automotive parts, which solves the problem that it is difficult to use mechanical structures for inspection because the inner cavity wall of the lug bracket fixture is non-planar.

[0005] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0006] An automotive parts stamping fixture inspection mechanism includes a bottom support plate, a guide rail mounted on the top of the bottom support plate, an inspection component slidably connected to the guide rail, an electric push rod connected to the top of the inspection component, a top support plate connected to the top of the electric push rod, and the top support plate fixedly mounted on the guide rail.

A vertical support rod is fixedly installed at the bottom of the slider, and a sleeve is fixedly installed at the bottom of the vertical support rod. A marker pen is inserted into the sleeve.

[0009] As a preferred embodiment of the automotive parts stamping fixture testing mechanism of this utility model, the rotating plate is provided with a T-shaped groove, and the inner wall of the T-shaped groove is slidably connected to a slider.

[0010] As a preferred embodiment of the automotive component stamping fixture testing mechanism of this utility model, it further includes a second support beam slidably connected to the guide rail, a support tube rotatably connected to the second support beam via a bearing, a rotating plate fixedly connected to the bottom of the support tube, and the upright passing through the rotating plate and the support tube.

[0011] As a preferred embodiment of the automotive component stamping fixture testing mechanism of this utility model, wherein: a driven gear is fixedly installed at the top end of the support tube, the driven gear is meshed with a driving gear, the driving gear is fixedly installed on a rotating shaft, a crank is fixedly installed at the top end of the rotating shaft, and the bottom of the rotating shaft is rotatably connected to a second support beam.

[0012] As a preferred embodiment of the automotive parts stamping fixture testing mechanism described in this utility model, the vertical support rod is always in contact with the outer wall of the lug bracket plate under the elastic force of the spring, and the diameter of the driving gear is smaller than the diameter of the driven gear.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] This utility model provides an inspection mechanism for stamping fixtures of automotive parts. Please refer to [link / reference]. Figure 1-5 It includes a bottom support plate 1, a guide rail 3 mounted on the top of the bottom support plate 1, a detection component slidably connected to the guide rail 3, an electric push rod 5 connected to the top of the detection component, a top support plate 4 connected to the top of the electric push rod 5, and the top support plate 4 fixedly mounted on the guide rail 3.

[0025] The detection assembly includes a first support beam 6 that is slidably connected to the guide rail 3, a vertical rod 19 is welded to the bottom of the first support beam 6, and a lifting lug bracket plate 20 is welded to the bottom of the vertical rod 19.

[0026] The detection assembly also includes a rotating plate 9, on which a slider 14 is slidably connected, and a support block 22 is welded to the bottom of the rotating plate 9. A T-shaped groove is formed on the rotating plate 9, and the top of the slider 14 is T-shaped. The slider 14 is slidably connected to the inner wall of the T-shaped groove. A spring 21 is fixedly installed between the slider 14 and the support block 22. Specifically, a first mounting plate and a second mounting plate are welded to the two ends of the spring 21, respectively. The first mounting plate is connected to the slider 14 by bolts, and the second mounting plate is connected to the support block 22 by bolts. A vertical support rod 15 is fixedly installed at the bottom of the slider 14. A sleeve 16 is fixedly installed at the bottom of 5. A marker 17 is inserted into the sleeve 16 and fixed to the sleeve 16 by bolts. The marker 17 is a grease pen. Under the elastic force of the spring 21, the vertical support rod 15 is always aligned with the outer wall of the lug bracket shape plate 20. The shape of the lug bracket shape plate 20 is the same as the inner cavity shape of the qualified lug bracket stamping fixture 23, and the size of the lug bracket shape plate 20 is smaller than the inner cavity size of the qualified lug bracket stamping fixture 23. The lug bracket shape plate 20 is formed by reducing the size of the plate material of the qualified lug bracket stamping fixture 23.

[0027] It also includes a second support beam 7 that is slidably connected to the guide rail 3. A support tube 8 is rotatably connected to the second support beam 7 via a bearing. A rotating plate 9 is fixedly connected to the bottom of the support tube 8. A vertical rod 19 passes through the rotating plate 9, the support tube 8 and the driven gear 18, and the vertical rod 19 does not contact the driven gear 18, the support tube 8 and the rotating plate 9.

[0028] A driven gear 18 is fixedly installed at the top of the support tube 8. The driven gear 18 is meshed with the driving gear 11. The diameter of the driving gear 11 is smaller than that of the driven gear 18, thereby reducing the angular velocity of the driven gear 18 and providing sufficient time for the spring 21 to contract, ensuring that the spring 21 drives the vertical support rod 15 to contact the outer wall of the lug bracket plate 20. The driving gear 11 is fixedly installed on the rotating shaft 12. A crank 13 is fixedly installed at the top of the rotating shaft 12. A bearing seat is fixedly installed on the second support beam 7. The bottom of the rotating shaft 12 is rotatably connected to the bearing seat through a bearing.

[0029] Four limiting blocks 2 are welded on the bottom support plate 1. The lifting lug bracket stamping fixture 23 is placed between the four limiting blocks 2. The four limiting blocks 2 are attached to the front, back, left and right sides of the lifting lug bracket stamping fixture 23, and the lifting lug bracket stamping fixture 23 is located directly below the lifting lug bracket shape plate 20.

[0030] In actual use, the electric push rod 5 extends and drives the first support beam 6 to descend, thereby lowering the entire detection assembly until the marker pen 17 enters the inner cavity of the lug bracket stamping fixture 23. The depth of the marker pen 17 inserted into the sleeve 16 is adjusted so that the pen tip of the marker pen 17 contacts the inner cavity wall of the lug bracket stamping fixture 23.

[0031] The hand crank 13 drives the rotating shaft 12 and the drive gear 11 to rotate. The drive gear 11 drives the driven gear 18 to rotate, which in turn drives the support tube 8 to rotate. The support tube 8 drives the rotating plate 9 to rotate, which in turn drives the slider 14, the vertical support rod 15, the sleeve 16, and the marker pen 17 to rotate together. If the marker pen 17 can rotate smoothly one revolution, and there is a complete revolution on the inner cavity of the lug bracket stamping fixture 23, then the inner cavity wall of the lug bracket stamping fixture 23 is qualified. If the marker pen 17 can rotate smoothly one revolution, but some parts of the inner wall of the lug bracket stamping fixture 23 are not marked, then there is a problem of depression in the unmarked parts, that is, the inner cavity wall of the lug bracket stamping fixture 23 is unqualified. If the marker pen 17 cannot rotate smoothly one revolution, then the part that is resisting the marker pen 17 and restricting the rotation is protruding, that is, the inner cavity wall of the lug bracket stamping fixture 23 is also unqualified.

[0032] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
