Problems solved by technology

[0002] After the production of the leaf spring is completed, the lifting lug of the leaf spring needs to be tested. The detection of the lifting lug usually uses the detection mandrel. The existing leaf spring detection mandrel is a measuring tool with a fixed size, which can only detect products of the corresponding size, resulting in Many models, difficult management, and loose coordination, inaccurate detection data

Embodiment 1

[0026] Such as Figure 1~3 As shown: the cross section of the mandrel body 1 is circular, and the middle part of the mandrel body 1 is provided with a detection part 101 whose diameter is larger than that of both ends. The length is less than the length of the mandrel body 1 on either side of the detection part 101 .

[0027] Both ends of the mandrel body 1 are symmetrically provided with ring-shaped measuring lines 102 around the mandrel body 1 , and the distances between the measuring lines 102 at both ends and the corresponding side of the detection part 101 are equal. One measuring point 103 is set on each measuring line 102 , and the line connecting the two measuring points 103 is set parallel to the axis of the mandrel main body 1 .

[0028] The mounting holes 104 are through holes arranged radially along the detection part 101. The mounting holes 104 are evenly distributed in three rows around the detection part 101. Each row is provided with two mounting holes 104, an...

Embodiment 2

[0033] The difference between Embodiment 2 and Embodiment 1 is that the installation hole 104 is a blind hole, one end of the spring 3 is supported on the bottom of the installation hole 104 , and the other end pushes the steel ball 2 to move outward and protrude out of the detection part 101 .

Abstract

The invention provides a multifunctional steel plate spring detection mandrel, and belongs to the technical field of steel plate spring detection equipment. The multifunctional steel plate spring detection mandrel is characterized by comprising a mandrel main body (1), a middle diameter of the mandrel main body (1) is greater than the diameters of both ends, a detection portion (101) is formed, atleast three radial mounting holes (104) are uniformly distributed around the detection portion (101) at intervals, a steel ball (2) is slidably installed at one end of each mounting hole (104), a spring (3) for pushing a steel ball to move outward is further arranged in each mounting hole (104), an outer side of the steel ball (2) is arranged to protrude from the detection portion (101), and oneend of the mounting hole (104) close to the steel ball (2) is provided with a limiting portion (105) having a diameter smaller than the diameter of the steel ball (2). The multifunctional steel platespring detection mandrel can detect lifting lugs of steel plate springs of various model numbers, the stress is uniform, after the lifting lugs of the steel plate springs are installed, the detectionmandrel is uniformly stressed and does not become loose, and the detection is accurate.

Description

technical field [0001] The invention discloses a multifunctional leaf spring detection mandrel, which belongs to the technical field of leaf spring detection equipment. Background technique [0002] After the production of the leaf spring is completed, the lifting lug of the leaf spring needs to be tested. The detection of the lifting lug usually uses the detection mandrel. The existing leaf spring detection mandrel is a measuring tool with a fixed size, which can only detect products of the corresponding size, resulting in There are many models, difficult management, and loose coordination, and the detection data is inaccurate. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a multifunctional leaf spring detection mandrel that can adapt to the detection of lifting lugs of various sizes and can detect accurately. [0004] The technical scheme adopted by the present ...
