[0016] The specific embodiments of the present application will be further described in combination with the drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present application, and cannot limit the protection scope of the present application.

[0017] As Figure 1 , Figure 2 , Figure 3 indicated, the present application is a bidirectional contact type measurement sensor. The measurement sensor comprises a base 1, a measuring arm mounting bracket 2, a cross spring mechanism 3 and a spring mechanism 4. The measuring arm mounting bracket 2 is provided with a swing arm 5. The upper part of the measurement sensor is provided with the cross spring mechanism 3, and the lower part of the measurement sensor is provided with the spring mechanism 4. The cross spring mechanism 3 comprises a first spring piece 31 and a second spring piece 32. The first spring piece 31 and the second spring piece 32 are arranged in a cross shape. The spring mechanism 4 is arranged on both sides of the swing arm 5. The measuring arm mounting bracket 2 is provided with a contact 6. The swing arm is connected with a magnetic rod. The base is provided with an induction coil. The magnetic rod and the induction coil are arranged correspondingly.

[0018] The base 1 is provided with a first spring sheet 31, the measuring arm mounting bracket 2 is provided with a second spring sheet 32, the first spring sheet 31 is provided with a first gasket 33 and a second gasket 34, and the second spring sheet 32 is provided with a third gasket 35 and a fourth gasket 36.

[0019] The spring sheet mechanism 4 comprises two spring sheet bodies which are the same in structure, and the spring sheet body comprises a compression spring 41, a spring sheet 42 and a measuring head 43; the base 1 is provided with the compression spring 41, the compression spring 41 is connected with the spring sheet 42, the spring sheet 42 is provided with the measuring head 43 in front, and the two measuring heads 43 are in contact with the lower end of the swing arm 5.

[0020] The compression spring 41 is fixed on the spring sheet 42 through a locking block 44.

[0021] The cross spring sheet mechanism 3 and the spring sheet mechanism 4 are used, so that the problem that the traditional contact type spring sensor can only measure in one direction is solved; for example, when the relative end face is flexibly measured, only one sensor needs to be arranged, and the linear displacement can be measured in sequence.

[0022] As shown in Figure 4 When the measuring arm mounting bracket 2 contacts the workpiece, the cross spring sheet mechanism 3 drives the magnetic rod below the swing arm 5 to move for measurement under the action of the force F1. When the measuring arm mounting bracket 2 leaves the workpiece, the cross spring sheet mechanism 4 is reset under the action of the spring sheet mechanism 4, so that the sensor returns to the state before measurement. Conversely, when the workpiece is measured in the opposite direction, the force F2 is also received.

[0023] The cross spring sheet mechanism 3 is designed, so that the measuring arm can measure in two directions. The spring sheet mechanism is used for positioning the rebound of the measuring arm, the sensor force can be adjusted, the influence of the friction force on the reset of the measuring arm after measurement is avoided, the repeated accuracy of the sensor is improved, the measurement repeatability of the sensor is greatly improved, and the repeated accuracy is improved.

[0024] The above merely describes the preferred embodiments of the utility model and is not used to limit the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
