Description

Technical Field

[0001] The utility model belongs to the technical field of pin shaft sensors, and in particular relates to a force measurement directional clamping plate for multi-pin shaft sensors. Background Art

[0002] Pin sensors are mainly used for connecting workpieces. They measure the force between connecting parts by means of voltage difference. Pin sensors are usually connected to rotating components to measure the force applied to the rotating components. The force measurement direction of the pin sensors is generally unidirectional. When the rotating component rotates, the pin sensors will rotate driven by the rotating component. If multiple rotating components are connected to the same mounting base, the rotation angles of the multiple rotating components are different, so the measurement directions of the multiple pin sensors connected to the rotating components are not consistent, which affects the accuracy of the measurement results.

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] A typical implementation of the present utility model is as follows Figure 1As shown, a multi-pin shaft sensor force measurement directional clamp includes a mounting base 1, the longitudinal cross-section of the mounting base 1 is U-shaped, including a horizontal plate 2 and a side plate 3, two side plates 3 are provided, the two side plates 3 are symmetrically arranged on both sides of the horizontal plate 2, a plurality of axial holes 4 are opened on the side plates 3, the multiple axial holes 4 on the two side plates 3 are arranged oppositely, the axes of the two opposite axial holes 4 on the two side plates 3 coincide, the diameter of the axial hole 4 is equal to the diameter of the pin shaft sensor 5, so that the pin shaft sensor 5 can pass through the two axial holes 4 arranged oppositely on the side plates 3.

[0022] In this embodiment, two axial holes 4 are provided on the side plate 3 on one side of the transverse plate 2, respectively located at the two ends of the side plate 3. The rotating component is fixed by inserting a pin sensor 5 into the axial hole 4. The mounting base 1 in this embodiment can fix the two rotating components through the pin sensor 5 to realize the rotational connection between the rotating component and the mounting base 1. When the rotating component rotates, the pin sensor 5 will be driven to rotate around its axis, resulting in inconsistent measurement force directions of the two pin sensors 5 on the mounting base 1, affecting the measurement results.

[0023] In order to solve the above problem, a positioning plate 6 is provided on one side of the mounting seat 1, and the positioning plate 6 is provided on the outer side of one of the side plates 3, such as Figure 2 As shown, positioning holes 7 are provided at both ends of the positioning plate 6. The two positioning holes 7 are respectively arranged corresponding to the two axial holes 4 on the side plate 3. The diameter of the positioning holes 7 is the same as the diameter of the pin shaft sensor 5. One end of the pin shaft sensor 5 passes through the two axial holes 4 and then passes through the positioning hole 7.

[0024] A positioning retaining ring 8 is provided on one side of the positioning plate 6 away from the side plate 3. The positioning retaining ring 8 is welded and fixed to the positioning plate 6. Two positioning retaining rings 8 are provided. The two positioning retaining rings 8 are fixed at two positioning holes 7 and are arranged along the outer edge of the positioning holes 7. The positioning retaining ring 8 is a cylindrical structure, and its inner diameter is the same as the inner diameter of the positioning hole 7, so that the positioning retaining ring 8 can be sleeved on the pin shaft sensor 5.

[0025] A bolt hole is provided at one end of the pin shaft sensor 5 close to the positioning retaining ring 8, and a bolt 9 can be passed through the bolt hole. The bolt 9 passes through the bolt hole and is connected to a nut, thereby limiting the axial displacement of the pin shaft sensor 5 and ensuring the stability of the connection between the pin shaft sensor 5 and the shaft hole 4.

[0026] Two limit holes 10 are symmetrically arranged on the outer wall of the positioning retaining ring 8. The diameter of the limit holes 10 is the same as the diameter of the bolt hole on the pin shaft sensor 5. The two limit holes 10 are arranged corresponding to the bolt holes of the pin shaft sensor 5. When the positioning retaining ring 8 is sleeved on the pin shaft sensor 5, the two limit holes 10 are respectively located at the two ends of the bolt hole and are connected with the bolt hole on the pin shaft sensor 5. At this time, one end of the bolt 9 passes through the limit hole 10 and the bolt hole in turn and is fixed by a nut. The two limit holes 10 and the bolt 9 are used to limit the rotation of the pin shaft sensor 5 along its axis, thereby preventing the pin shaft sensor 5 from rotating with the rotating component, so that the measuring directions of the two pin shaft sensors 5 are always consistent, thereby ensuring the accuracy of the measurement results.

[0027] The utility model provides a positioning plate on one side of the mounting seat, a positioning hole corresponding to the axial hole of the mounting seat is formed on the positioning plate, a positioning retaining ring capable of being sleeved on the pin shaft sensor is formed on one side of the positioning hole, and a limiting hole is formed on the positioning retaining ring, and bolts are sequentially passed through the limiting hole and the bolt hole on the pin shaft sensor, thereby limiting the rotation of the pin shaft sensor around its axis, ensuring that the measurement directions of multiple pin shaft sensors on the same mounting seat are consistent, thereby ensuring the accuracy of the measurement results.

[0028] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. 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.
