Technical Field

[0001] The utility model relates to the technical field of ball screws, in particular to a ball screw friction force detection device. Background Art

[0002] Ball screws are the most commonly used transmission components in tool machinery and precision machinery. Their main function is to convert rotational motion into linear motion, or torque into axial repetitive force. They also have the characteristics of high precision, reversibility, and high efficiency. After the ball screw is processed, the friction force of the screw parts will be tested. This testing equipment is used to test the screw parts.

[0003] When testing a ball screw, a large number of sensor components are used to detect the displacement and force parameters of the screw components, and a large number of transmission components are used to drive the screw components. This makes the entire structure complex, maintenance and repair time-consuming and labor-intensive, and is not conducive to quick and convenient testing of the screw components.

[0025] Example 2:

[0026] Based on the first embodiment, Figure 1 and Figure 2 As shown, the vertical central axes of the machine 1 and the storage chamber 2 coincide with each other, the machine 1 and the assembly base 3 are fixedly connected, and the assembly base 3 and the screw 5 are threadedly connected, and the assembly base 3 and the push rods 6 are fixedly connected, and the number of the push rods 6 is twice the number of the assembly base 3. By rotating the screw 5, the screw 5 moves downward and presses against the end wall of the screw member placed in the through-hole 4. In conjunction with the two push rods 6, the screw member is locked and limited, which facilitates the quick and convenient disassembly and assembly of the screw member. The two through-holes 4 are used to place two groups of screw members and detect two screw members at the same time, which is convenient for improving the efficiency of screw member detection.

[0027] Based on the first embodiment, Figure 3 and Figure 4 As shown, the bar sub-series 8 and the hanging rope 9 are fixedly connected, the hanging rope 9 and the hanging seat 10 are fixedly connected, and the hanging seat 10 and the screw 12 are threadedly connected.

When the force of the counterweight plate 13 applied to the lever sub-series 8 is greater than the friction between the ball bearings of the lever sub-series 8 and the screw 7, the lever sub-series 8 will rotate, thereby obtaining the friction between the lever sub-series 8 and the screw 7, and the efficiency of the entire structure detection is higher.
