With the increasing demands for thread quality in the machining industry, the shortcomings of existing tapping torque testing machine fixed bases in terms of clamping flexibility, vibration suppression, and installation adaptability are becoming increasingly apparent. Existing tapping torque testing machines only adjust the clamping blocks in one direction, making them unsuitable for test pieces of different sizes. When testing workpieces of different specifications, special fixtures must be replaced, which is cumbersome and increases equipment costs. Therefore, this paper proposes a fixed base for tapping torque testing machines. Utility Model Content

The longitudinal adjustment component can drive the test piece to move axially along the L-shaped base, and the lateral adjustment component can drive the test piece to move laterally, which facilitates longitudinal and lateral position calibration. The operation is convenient and the equipment cost is reduced, thus overcoming the shortcomings of existing technologies.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Example 1, referring to Figure 1-4 A fixed base for a tapping torque testing machine includes a testing machine body 1. An L-shaped base 7 is provided on the testing machine body 1. A longitudinal adjustment component is installed on the vertical section of the L-shaped base 7. A transverse adjustment component is installed on the longitudinal adjustment component. A bearing seat 12 is connected to the transverse adjustment component. A fixed seat 10 and a connecting block 14 are fixed on the bearing seat 12. A first adjusting screw 16 is screwed onto the connecting block 14. A clamping plate 15 is rotatably connected to the end of the first adjusting screw 16 near the fixed seat 10 through a bearing. The lower end of the clamping plate 15 slides against the upper end surface of the bearing seat 12.
[0023] The longitudinal adjustment assembly includes a servo motor 8 fixed on one side of the vertical section of the L-shaped base 7. The output end of the servo motor 8 extends to the other side of the vertical section of the L-shaped base 7 and is connected to a threaded rod 9. A movable seat 4 is screwed onto the threaded rod 9. The bottom end of the movable seat 4 is in sliding contact with the horizontal section of the L-shaped base 7.
[0024] Two support rods 5 are symmetrically fixed on the vertical section of the L-shaped base 7, and the two ends of the movable seat 4 are respectively slidably sleeved on the two support rods 5.
[0025] Protective tubes 13 are fixed on the outer walls of opposite sides of the movable seat 4, and both protective tubes 13 are located on the outside of the threaded rod 9.
[0026] The lateral adjustment assembly includes an L-shaped support plate 3 fixed to one side of the movable seat 4. A U-shaped adjustment rod 2 is slidably inserted into the vertical section of the L-shaped support plate 3. A second adjustment screw 11 is rotatably connected to one side of the vertical section of the L-shaped support plate 3 via a bearing. The second adjustment screw 11 is screwed to the middle of the U-shaped adjustment rod 2.
[0027] The test piece is placed on the support seat 12. By rotating the first adjusting screw 16, the clamping plate 15 moves towards the fixed seat 10. The fixed seat 10 and the clamping plate 15 clamp the test piece. The servo motor 8 is controlled by the control switch on the test machine body 1 to drive the threaded rod 9 to rotate, so that the threaded rod 9 drives the moving seat 4 to move. Then, the position of the test piece can be adjusted axially on the L-shaped base 7. By rotating the second adjusting screw 11, the support seat 12 can be moved on the moving seat 4 through the U-shaped adjusting rod 2 to realize the lateral adjustment of the test piece, thereby facilitating the calibration of the test piece's position in the longitudinal and lateral directions.
[0028] Example 2 is an optimization based on Example 1, specifically:
[0029] The lower end of the L-shaped base 7 is provided with a rubber seat 6, and the side of the clamp 15 facing the fixed seat 10 is provided with anti-slip rubber particles.
[0030] The rubber seat 6 reduces the transmission of positional vibrations, preventing the position of the test piece from changing due to external vibrations. By setting anti-slip rubber particles on the clamping plate 15, the test piece can be prevented from moving when clamped, thus improving stability.
[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
