According to the utility model discloses, can be favorable to pressing from both sides tight determinand and be convenient for carry out impact test to the different positions of determinand. The jig for the drop impact test according to the present embodiment may be referred to as a jig for a drop impact test, a device for a drop impact test, or the like, and may be simply referred to as a jig.

Hereinafter, a drop impact test jig having a vertical clamping function according to the present embodiment will be described in detail with reference to the drawings.

Fig. 1 is an overall schematic view showing a jig 1 according to the present invention. In the present embodiment, the jig 1 may include an upper deck 10, a lower deck 20 located below the upper deck 10, a lifting mechanism 30, and a guide 40 (see fig. 1).

In addition, it should be noted that relative position and relative direction terms such as "above", "upward", "below", "downward", "up-down direction", "left", "right", "left-right direction", "front", "rear", "front-rear direction" and the like in this document refer to a normal operation posture and should not be considered as restrictive.

Referring to fig. 1, in some examples, the lift mechanism 30 may include a lift stage 310 disposed between the upper deck 10 and the lower deck 20, and a driving mechanism 320 driving the lift stage 310. That is, the driving mechanism 30 may drive the lift table 310 to be close to the upper deck 10, and may also drive the lift table 310 to be far from the upper deck 10.

In some examples, the upper deck 10 may be a plate-like structure parallel to the horizontal plane.

In some examples, the upper deck 10 may have a fastening means (not shown). In some examples, the fastening means of the upper deck 10 may be screw holes or clamping plates provided at the sides of the upper deck 10. In this case, the upper deck 10 can be fastened to other objects, such as a wall, a laboratory table, a steel frame, etc., by fastening means. In this example, the lower plate 20 can be omitted to adapt to different application scenarios of the fixture 1.

In some examples, the jig 1 may include an underlying plate 20. In some examples, the lower plate 20 may be a base of the jig 1. A plurality of rolling wheels (not shown) may be provided on the outer periphery of the lower surface of the lower deck 20, thereby facilitating the movement of the jig 1. In some examples, the periphery of the lower surface of the lower bearing plate 20 may also be provided with sound insulation cotton pads (not shown), so that the jig 1 can be moved without much friction noise and is not easy to damage the ground during use.

In some examples, the outer rim of the lower deck 20 protrudes toward the upper deck 10 to form the lower deck 20 in a depression shape. In some examples, the outer edge of the lower deck 20 may form a fully enclosed protrusion. In addition, in some examples, the outer edge of the lower deck 20 may also form a protrusion that is not fully enclosed. In addition, in some examples, the outer edge of the lower deck 20 may form an annular groove inward of the protrusion in addition to the protrusion. In this case, after the test steel ball 70 falls, when the lifting platform 310 is far away from the upper supporting plate 10, the test steel ball 70 slides off the object 80 to be tested, and the movement of the test steel ball 70 is limited by the groove or the protrusion of the lower supporting plate 20, so that the test steel ball 70 is not easy to fall out of the jig 1.

In some examples, the jig 1 may include a guide 40. In some examples, the guide 40 has a guide rail 410 extending in a direction directed from the upper deck 10 toward the lift table 310.

In some examples, the upper deck 10 may have a through hole penetrating in a vertical direction, and the guide rail 410 is aligned with the through hole of the upper deck 10. In this case, the hollow passage can communicate with the upper deck 10, and when the test steel ball 70 is released from above the guide 4, the movement trace of the test steel ball 70 can pass through the through hole.

In some examples, the guide 40 may be in the shape of a hollow cylinder. Additionally, in some examples, the axial direction of the guide 40 may be along a vertical direction. Therefore, the movement track of the steel ball 70 for test can be limited in the hollow column, and the steel ball 70 for test can fall from the opening at the other end of the hollow column. Additionally, in some examples, the guide 40 may be an inclined slide rail. Thereby, the test steel ball 70 can slide down along the guide 40. In addition, in some examples, the guide 40 may be a ring that is vertically oriented to a predetermined position on the top surface of the lift table.

Fig. 6 is a schematic structural view showing a guide 40 according to an example of the present invention.

Referring to fig. 6, in some examples, the guide track 410 may be a hollow channel of the guide 40. In some examples, the guide rail 410 may be composed of two hollow pipes, the guide rail 410 may include an upper hollow pipe 411 and a lower hollow pipe 412, an outer diameter of the hollow pipe 411 is substantially the same as an inner diameter of the hollow pipe 412, and a lower end of the hollow pipe 411 protrudes into an upper end of the hollow pipe 412 to form a multi-stage hollow pipe. Thus, the hollow pipe 411 and the hollow pipe 412 may be moved or fixed to each other, forming test pipes of different lengths.

In addition, in some examples, a scale is provided on the outer surface of the hollow duct 411 (see fig. 6). In this case, the height of the upper end of the guide 40 from the upper surface of the object 80 can be precisely adjusted.

It should be noted that, although two hollow pipes are shown in the example (see fig. 6), it is not meant that the guide rail 410 is only composed of two hollow pipes, and should not be considered as a limitation to the number of hollow pipes, and the guide rail 410 may also be composed of a plurality of hollow pipes.

Fig. 3 is a schematic diagram showing the operation of the laser positioner 90 according to an example of the present invention.

In some examples, a laser locator 90 may be disposed on the guide 40. The laser emitted by the laser positioner 90 may propagate along the hollow passage toward the upper surface of the lift table 310 (see fig. 3). In this case, the position of the object 80 to be tested can be adjusted on the lifting table by laser irradiation before the drop test, so that the preset test position of the object 80 to be tested is consistent with the laser irradiation position, and the preset test position of the object 80 to be tested is consistent with the drop position of the test steel ball 70. However, it is easily understood by those skilled in the art that the method for adjusting the position to be tested of the object 80 in advance by using the laser positioner according to the present invention is also applicable to the method for adjusting by using other instruments (for example, a long straight stick-shaped or linear instrument), or is applicable to slight adjustment without creative work.

In some examples, the lift mechanism 30 may include a drive mechanism 320. In some examples, the drive mechanism 320 may drive the lift table 310 to move in a vertical direction. In this case, it is advantageous that the object 80 can be gripped by the lifting table 310 (see fig. 2) when the object 80 is placed on the lifting table 310 at different positions and the lifting table 310 is close to the upper deck 10.

In some examples, the drive mechanism 320 may be a pneumatic cylinder or a hydraulic cylinder. In fig. 1, a plurality of components having the same function or function are indicated by one symbol, and the number of the components is not limited. For example, one drive mechanism 320 is labeled in fig. 1, but fig. 1 actually shows a plurality of drive mechanisms 320. The driving mechanism 320 according to the present embodiment will be described below by taking a cylinder as an example.

Fig. 4A is a schematic view showing a state where the lift table 310 according to an example of the present invention is close to the upper deck 10; fig. 4B is a schematic diagram illustrating a state where the lifting platform 310 according to the example of the present invention is far from the upper deck 10.

Referring to fig. 4A and 4B, in some examples, the cylinder may include a cylinder 321, a piston movably disposed in the cylinder, and a piston rod 322 connected to the piston, the cylinder 321 is fixedly disposed on the upper deck 10, and one end of the piston rod 322 is connected to the piston and the other end is connected to the lifting platform 310. In this case, the oil cylinder can drive the lift table 310 to approach or separate from the upper deck 10.

In some examples, a cylinder 321 is disposed on an upper surface of the upper deck 10, and a piston rod 322 is connected to the lift table 310 through a through hole of the upper deck 10. In this case, when the driving mechanism 320 drives the lifting platform 310 to be close to or far away from the upper bearing plate 10, since the cylinder part is disposed on the upper bearing plate 10, the piston rod 322 has a longer stroke, and can test the object 80 to be tested with a larger thickness, so that the overall space utilization rate of the jig 1 is larger.

In some examples, the cylinder 321 may be disposed on the upper surface of the lower plate 20, and one end of the piston rod 322 is connected to the piston and the other end is connected to the lifting platform 310. In this case, the driving mechanism 320 may drive the lifting platform 310 to move up and down, and when the positions of the upper and lower bearing plates 10 and 20 are fixed, the lifting platform 310 is lifted up to cooperate with the upper bearing plate 10 to clamp the object 80.

In some examples, the lower surface of the upper deck 10 and the upper surface of the lift table 310 may be parallel to a horizontal plane. In this case, the object 80 is placed on the upper surface of the lifting table 310, the position to be tested of the object 80 clamped when the lifting table 310 approaches the upper deck 10 is in the horizontal plane, and the object 80 is not easily loosened or slid. In some examples, the lift table 310 may be a plate-like structure parallel to a horizontal plane.

In some examples, the upper surface of the lift table 310 may be provided with a magnetic confinement portion 50. In some examples, the magnetic restraint 50 may be a magnet placed on the upper surface of the lift table 310 (see fig. 5). In addition, in some examples, the magnetic constraining part 50 may be a ring-shaped magnet or an electromagnet embedded on the upper surface of the lifting platform 310, and the outer edge and the inner edge of the ring-shaped magnet may be circular, elliptical or square. In this case, after the test steel ball 70 falls, when the lifting table 310 is away from the upper deck 10, the test steel ball 70 slides off the object 80, and the movement of the test steel ball 70 is restricted by the magnetic restricting portion 50, so that the test steel ball 70 can be conveniently recycled.

Referring to fig. 1, in some examples, a tie bar 60 may be disposed between an upper carrier plate 10 and a lower carrier plate 20, and the upper carrier plate 10 and the lower carrier plate 20 are plate-shaped and fixedly disposed at both ends of the tie bar 60, respectively. In this case, the upper carrier plate 10 and the lower carrier plate 20 are more firmly fixed together, which can increase the overall strength of the jig 1. In fig. 1, a plurality of components having the same function or function are denoted by one symbol, and the number of the components is not limited thereto. For example, one tie bar 60 is labeled in fig. 1, but fig. 1 actually shows a plurality of tie bars 60.

In some examples, the number of tie posts 60 may be one or more. In some examples, the number of golling pillars 60 may be 1 to 8, such as 1, 2, 3, 4, 5, 6, 7, or 8.

In some examples, the lift table 310 may be provided with a plurality of through holes matching the tie bars 60, and the same number of tie bars 60 may pass through the through holes to connect the upper and lower bearing plates 10 and 10. In this case, due to the fitting of the tie bar 60 and the through hole, when the driving mechanism 320 drives the elevating platform 310 to move, the movement of the elevating platform 310 can be more stabilized.

In some examples, the number of through holes on the lift table may be one or more. In some examples, the number of through holes on the lift table may be 1 to 8, such as 1, 2, 3, 4, 5, 6, 7, or 8, and match the number of golling posts 60.

While the present invention has been described in detail in connection with the drawings and examples, it is to be understood that the above description is not intended to limit the invention in any way. The present invention may be modified and varied as necessary by those skilled in the art without departing from the true spirit and scope of the invention, and all such modifications and variations are intended to be included within the scope of the invention.
