As shown in Figure 1 and shown in Figure 2As shown in the figure, a new type of shock response spectrum test sensor includes a test box body 1, and support legs 2 are respectively and fixedly connected to the four corner parts at the lower part of the test box body 1; a placement plate 3 is fixedly connected to the middle and lower side inside the test box body 1, and through grooves are respectively opened on the left and right sides of the middle part inside the placement plate 3, and sliders 4 are respectively and slidably arranged inside the through grooves; clamping blocks 5 are respectively fixedly connected to the upper ends of the sliders 4, and the clamping blocks 5 are respectively slidably arranged on the upper part of the placement plate 3; V-shaped grooves are respectively opened on the inner middle sides of the clamping blocks 5; threaded through holes are respectively and horizontally opened on the lower sides inside the sliders 4, and the threaded through holes are respectively located on the lower side of the placement plate 3; a threaded rod 6 is internally threaded between the threaded through holes, and the threaded rod 6 is connected by a bearing to the middle and lower side inside the test box body 1, and the right end of the threaded rod 6 penetrates through the right side inside the test box body 1; an operating handle 7 is fixedly connected to the right end of the threaded rod 6; electromagnets 8 are respectively fixedly connected to the left and right sides of the middle part at the upper side inside the test box body 1.

[0014] Among them, a new type of shock response spectrum test sensor further includes a guided impact component 9, and the guided impact component 9 is fixedly connected to the opening at the middle and upper side inside the test box body 1; the electromagnets 8 are respectively adsorbed and connected to the guided impact component 9, which is beneficial to achieving the effect of guided impact, can effectively avoid the problem that the impact hammer 95 is bounced off, thereby can effectively avoid the problem that the impact hammer 95 is likely to damage other structures, and further can improve the service life of the test sensor.

[0015] Among them, the threaded rod 6 adopts a double-headed screw, and the thread directions on the left and right sides of the outer wall of the threaded rod 6 are opposite.

[0016] In this implementation scheme, in combination with the attached Figure 3 As shown in the figure, the guided impact component 9 includes a guide sleeve 91, mounting openings are respectively opened at the four surrounding parts on the upper side inside the guide sleeve 91, and rollers 92 are respectively axially connected from top to bottom in the middle part inside the mounting openings; a sliding rod 93 is arranged inside the roller 92; a spherical handle 94 is integrally connected to the upper end of the sliding rod 93; an impact hammer 95 is fixedly connected to the lower end of the sliding rod 93.

[0017] In this implementation scheme, specifically, the lower side of the outer wall of the guide sleeve 91 is fixedly connected to the opening at the middle and upper side inside the test box body 1.

[0023] In this embodiment, when testing a workpiece, the operator needs to first place the workpiece on the upper part of the placement plate 3, and then rotate the threaded rod 6 through the operating handle 7, so that the threaded rod 6 drives the clamping block 5 to move inward through the slider 4 until the clamping block 5 clamps the workpiece. Then, the operator can control the start of the electromagnet 8 through the external control panel, so that the electromagnet 8 loses magnetism, and the impact hammer 95 will fall by itself and impact the workpiece. During the fall of the impact hammer 95, since the sliding rod 93 is located inside the roller 92, the degree of freedom of the sliding rod 93 can be restricted through the roller 92, so that the sliding rod 93 can only move up and down. Furthermore, the degree of freedom of the impact hammer 95 can be restricted through the sliding rod 93, effectively avoiding the problem that the impact hammer 95 is bounced off after impacting the workpiece, achieving the effect of guiding the impact, effectively avoiding the problem that the impact hammer 95 is bounced off, thus effectively avoiding the problem that the impact hammer 95 is likely to damage other structures, and further improving the service life of the test sensor.
