The limit assembly is arranged on the base 11, and a limited space is arranged on the base 11. The leaf spring 2 is arranged in the limited space away from the ear. The limit assembly is used to lock and limit the leaf spring 2 in the limited space away from the ear, so as to ensure the subsequent parallelism detection accuracy of the ear of the leaf spring 2. The detection component 3 is arranged on the bottom plate 1, and the detection component 3 is located at one end of the base 11. The coil ear of the leaf spring 2 is sleeved on the detection component 3. The detection component 3 is used to compare the center line of the coil ear of the leaf spring 2 with the longitudinal plane of the leaf spring 2 (refer to Figure 1 The parallelism of the leaf spring 2 and the fitting surface of the limit assembly is measured. In this embodiment, the leaf spring 2 is fixed on the base 11 as a whole away from the ear by using the limit assembly, and then the ear of the leaf spring 2 is sleeved on the detection assembly 3. The parallelism of the ear of the leaf spring 2 and the longitudinal plane of the leaf spring 2 is measured by the detection assembly 3 to detect the degree of forming of the ear of the leaf spring 2. That is, this test fixture can selectively detect the ears at both ends of the leaf spring 2, so as to facilitate the adjustment of the leaf spring 2 ear execution equipment, thereby ensuring the processing and detection efficiency of the ear of the leaf spring 2. It also effectively solves the shortcoming in the prior art that the parallelism detection of the ear of the leaf spring 2 cannot be detected at one end, resulting in low detection efficiency.

[0040] Reference Figure 2In this embodiment, the detection assembly 3 includes: a support seat 31, a support column 32, a swinging member 33, a sleeve column 34 and a measuring member 35. The support seat 31 is arranged on the bottom plate 1, and the support seat 31 is located at one end of the base 11. The sleeve column 34 is cylindrical, and the sleeve column 34 is sleeved in the coil ear of the leaf spring 2. The sleeve column 34 is adapted to the inner hole of the coil ear of the leaf spring 2, so as to realize the use of the sleeve column 34 to replace the setting state of the inner hole of the coil ear of the leaf spring 2 as a whole, so as to facilitate the detection of the setting state of the inner hole of the coil ear of the leaf spring 2 and the parallelism of the longitudinal surface of the leaf spring 2. A U-shaped groove (not marked in the figure) is opened on one side of the support column 32, and the opening direction of the U-shaped groove of the support column 32 is perpendicular to the longitudinal plane of the leaf spring 2. The support column 32 is provided with a connecting hole (not marked in the figure) in the U-shaped groove, so as to facilitate the subsequent connection of the swinging member 33 in the U-shaped groove of the support column 32. The swing member 33 is V-shaped, and the V-shaped opening of the swing member 33 is arranged in a direction perpendicular to the longitudinal plane of the leaf spring 2, and measuring ends 332 are respectively arranged at both ends of the V-shaped opening of the swing member 33. The swing member 33 is respectively abutted against the upper and lower parts of the sleeve column 34 through the two measuring ends 332. The swing member 33 is provided with a first connecting shaft 331 away from the V-shaped opening, and the swing member 33 is rotatably connected to the U-shaped groove of the support column 32 through the first connecting shaft 331.

One end of the measuring piece 35 is slidably connected to the bottom of the support column 32, and the other end of the measuring piece 35 is hinged to the bottom end of the swinging piece 33, so as to realize the use of the sleeve column 34 to replace the setting state of the inner hole of the ear of the leaf spring 2 as a whole. The swinging state is formed by the abutment of the two measuring ends 332 on the swinging piece 33 with the sleeve column 34, and then the sliding distance of the measuring piece 35 on the support column 32 is used to judge the parallelism of the setting state of the inner hole of the ear of the leaf spring 2 and the longitudinal plane of the leaf spring 2, so as to determine the curvature of the ear of the leaf spring 2 at one end of the leaf spring 2. That is, in this embodiment, the working principle of the measuring assembly is as follows: the setting state of the inner hole of the ear of the leaf spring 2 is replaced as a whole through the sleeve column 34, and then the two measuring ends 332 of the swing member 33 are abutted against the upper and lower parts of the sleeve column 34. At this time, the swinging state of the swing member 33 in the U-shaped groove on the support column 32 is the setting state of the inner hole of the ear of the leaf spring 2, that is, if the setting state of the inner hole of the ear of the leaf spring 2 is set in an inclined state, the setting state of the swing member 33 and the sleeve column 34 is also inclined. At this time, a measuring piece 35 is set at the bottom or top of the support column 32. By measuring the measuring piece 35 inside the support column 32, the relationship between the setting state of the inner hole of the ear of the leaf spring 2 and the longitudinal plane of the leaf spring 2 can be read.That is, in actual measurement, the sliding distance of the measuring member 35 inside the support column 32 when the swing member 33 and the sleeve column 34 are in a horizontal state can be predetermined, and this can be used as a standard value to judge the parallel relationship between the setting state of the inner hole of the coiled ear of the leaf spring 2 and the longitudinal plane of the leaf spring 2. In this embodiment, in order to better allow the sleeve column 34 to replace the setting state of the inner hole of the coiled ear of the leaf spring 2 as a whole, the bottom end of the sleeve column 34 is provided with a butt joint 341, and the butt joint 341 is spherical, and the butt joint 341 abuts on the bottom plate 1 to achieve the overall replacement of the setting state of the inner hole of the coiled ear of the leaf spring 2 with the sleeve column 34. That is, in this embodiment, the leaf spring 2 is fixed and limited away from the coiled ear, and then the coiled ear of the leaf spring 2 is sleeved on the sleeve column 34. At this time, the sleeve column 34 uses the butt joint 341 to replace the setting state of the inner hole of the coiled ear of the leaf spring 2 as a whole.

[0041] In this embodiment, in order to ensure the sliding effect of the measuring member 35 inside the support column 32, the measuring member 35 is hingedly connected to the swing member 33 through a connecting assembly. Specifically, the connecting assembly includes: a connecting member 352. One end of the connecting member 352 is connected to one end of the swing member 33, and the other end of the connecting member 352 is rotatably connected to the measuring member 35 through a second connecting shaft 351.

Preferably, one end of the connecting member 352 is detachably connected to one end of the swing member 33 through a thread, that is, an external thread is provided on one end of the connecting member 352, and an internal thread is provided on one end of the swing member 33, and one end of the connecting member 352 is detachably connected to one end of the swing member 33 through a thread.

[0042] In this embodiment, in order to ensure the abutment detection effect between the two measuring ends 332 of the swing member 33 and the sleeve column 34, the swing member 33 is provided with an inner groove at the measuring end 332, and the swing member 33 abuts against the sleeve column 34 through the inner groove. Preferably, the inner groove is V-shaped, and the V-shaped opening direction of the inner groove is horizontally arranged, that is, the setting direction of the inner groove is perpendicular to the V-shaped opening direction of the swing member, so as to ensure the abutment detection accuracy between the measuring end 332 of the swing member 33 and the sleeve column 34.

The limiting plate 13 is arranged on one side of the top of the base 11, and the limiting plate 13 is arranged vertically. The limiting plate 13 is in contact with a side of the leaf spring 2 away from the coiling ear. One side of the limiting member 12 is convex, and the limiting member 12 is rotatably connected to the base 11. The limiting member 12 is located on one side of the limiting plate 13, and the convex shape of the limiting member 12 is in contact with the other side of the leaf spring 2 away from the coiling ear, so as to realize that the convex shape of the limiting member 12 is in contact with the other side of the leaf spring 2, so as to limit the leaf spring 2 as a whole in the limiting space between the limiting member 12 and the limiting plate 13. In order to facilitate the movement of the limiter 12, the limiter assembly further includes: a swing rod 121, one end of which is connected to the limiter 12, and the swing rod 121 is used to move the protrusion of the limiter 12 to abut against the other side of the leaf spring 2. In this embodiment, the leaf spring 2 is limited as a whole by using the protrusion of the limiter 12 to cooperate with the limiter plate 13, so that the detection component 3 can measure the parallelism of the ear of the leaf spring 2. Preferably, the limiter 12 is a cam column to meet the need of abutting against the other side of the leaf spring 2. In some feasible embodiments, in order to prevent the limiter 12 from over-extruding the surface of the leaf spring 2, the distance between the protrusion of the limiter 12 and the limiter plate 13 is adapted to the thickness of the leaf spring 2, that is, the protrusion of the limiter 12 and the limiter plate 13 can only limit and fix the leaf spring 2.
