Description

Technical Field

[0001] This utility model relates to the field of stress testing technology, and in particular to a stress testing instrument. Background Technology

[0002] As a widely used container, the internal stress of glass bottles has a crucial impact on their mechanical strength and thermal stability. The presence of internal stress can weaken the overall performance of glass bottles, especially during transportation, high-temperature sterilization, pharmaceutical filling, and long-term storage. Excessive internal stress may cause the bottles to break, thereby affecting the safety and quality of the product.

[0003] The prior art CN218916631U discloses a glass bottle strength testing device, including a glass stress meter body, an analyzer that is lifted and mounted on the glass stress meter body, and a stage fixedly mounted on the glass stress meter body. The beneficial effect of this utility model is that through the cooperation of the support components, studs, sliders, U-shaped plates, pillars, supports and drive components, the glass bottle can be mounted on the outer wall of the pillars and supports and can be driven to rotate by the supports. The glass bottle is located above the stage, so the operator does not need to manually rotate the glass bottle when conducting a comprehensive test of the internal stress of the glass bottle, which provides convenience for the strength test of the glass bottle. In addition, the glass bottle will not contact the stage when rotating, avoiding wear on the mirror surface of the stage. At the same time, the distance between the pillars and supports is adjustable, which can be used to stably mount glass bottles of various sizes above the stage, making it highly applicable.

[0004] However, the above-mentioned existing technology has the following problems: friction will be generated at the contact point between the glass bottle and the support column. If the friction is insufficient, the glass bottle will not rotate synchronously with the support column, resulting in uneven detection. Conversely, excessive friction may cause wear on the bottom of the glass bottle or cause the bottle to slip in some cases.

[0005] Therefore, it is necessary to provide a stress testing instrument to solve the above-mentioned technical problems. Summary of the Invention

[0006] This invention overcomes the shortcomings of the prior art and provides a stress testing instrument.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a stress testing instrument, comprising: a chassis, an analyzer disposed on the upper part of the chassis, a stage for carrying objects disposed on the upper surface of the chassis, and clamping mechanisms disposed on both sides of the stage for carrying objects.

[0008] The clamping mechanism includes: a first clamping block and a second clamping block distributed on both sides of the objective stage; a first connecting rod is provided on one side of the first clamping block, and a second connecting rod is provided on one side of the second clamping block;

[0009] The upper surface of the chassis is provided with two mounting plates, and the two mounting plates are rotatably connected to the first connecting rod and the second connecting rod respectively through rolling bearings;

[0010] Both the first connecting rod and the second connecting rod are provided with a first synchronous pulley, and a drive assembly is provided inside the chassis, which drives the first connecting rod and the second connecting rod to rotate synchronously.

[0011] In a preferred embodiment of this utility model, the first clamping block is frustum-shaped, and the smaller the distance between it and the second clamping block, the smaller its cross-sectional diameter.

[0012] In a preferred embodiment of this utility model, the second clamping block is cylindrical.

[0013] In a preferred embodiment of this utility model, both the first clamping block and the second clamping block are made of rubber.

[0014] In a preferred embodiment of this utility model, the first clamping block and the second clamping block are on the same axis.

[0015] In a preferred embodiment of the present invention, the drive assembly includes: a dual-head motor disposed within the chassis, two transmission rods disposed at the two output ends of the dual-head motor, a second synchronous pulley disposed on each of the two transmission rods, a synchronous belt disposed on the second synchronous pulley, and the second synchronous pulley driving the first synchronous pulley to rotate via the synchronous belt.

[0016] In a preferred embodiment of this utility model, a limiting groove is formed on the surface of the second connecting rod, and a limiting rod is provided in the limiting groove. The inner wall of the first synchronous pulley and the rolling bearing on the mounting plate are both provided with slots that match the limiting rod. The second connecting rod is slidably connected to the first synchronous pulley and the inner wall of the rolling bearing on the mounting plate through the limiting rod.

[0017] In a preferred embodiment of this utility model, a limiting screw is provided on the upper surface of the limiting rod, and the lower end of the limiting screw abuts against the inner wall of the limiting groove.

[0018] In a preferred embodiment of this invention, the length of the first connecting rod is less than that of the second connecting rod.

[0019] In a preferred embodiment of this invention, the second clamping block moves along the axis of the second connecting rod.

[0020] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0021] (1) This utility model provides a stress testing instrument. Through the setting of the clamping mechanism, a first clamping block and a second clamping block are used to clamp the glass bottle from both ends. One end abuts against the bottom of the bottle, and the other end is inserted into / abuts the bottle mouth. The two ends rotate coaxially, thereby driving the glass bottle to rotate. When technicians conduct comprehensive testing of the internal stress of the glass bottle, they do not need to manually rotate the glass bottle, and the rotation speed is constant and controllable. This solves the problems of wear caused by the contact between the glass bottle and the objective stage, as well as the bottle body friction, uneven rotation speed, or even failure to rotate during the rotation process in the prior art.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] like Figure 1 and Figure 2As shown, a stress testing instrument includes: a housing 1, an analyzer 2 disposed on the upper part of the housing 1, an objective lens stage 3 disposed on the upper surface of the housing 1, and clamping mechanisms 4 disposed on both sides of the objective lens stage 3; the clamping mechanism 4 includes: a first clamping block 6 and a second clamping block 7 distributed on both sides of the objective lens stage 3; a first connecting rod 61 is disposed on one side of the first clamping block 6, and a second connecting rod 71 is disposed on one side of the second clamping block 7; two mounting plates 8 are disposed on the upper surface of the housing 1, and the two mounting plates 8 are rotatably connected to the first connecting rod 61 and the second connecting rod 71 respectively through rolling bearings; a first synchronous pulley 9 is disposed on both the first connecting rod 61 and the second connecting rod 71; a drive assembly is disposed inside the housing 1, and the drive assembly drives the first connecting rod 61 and the second connecting rod 71 to rotate synchronously.

[0030] Furthermore, the analyzer 2 is connected to the housing 1 via two columns and a lifting mechanism. The analyzer 2 is mounted on a flat plate parallel to the objective stage 3, which can be rectangular or U-shaped. The flat plate has two through holes and one threaded hole, with the two through holes allowing the two columns to pass through respectively. The lifting mechanism includes a threaded rod parallel to the two columns, preferably positioned between them. The lower end of the threaded rod is rotatably connected to the housing 1, and the threaded rod is threadedly connected to the flat plate through the threaded hole. By rotating the threaded rod, the distance between the flat plate, i.e., the analyzer 2, and the objective stage 3, is adjustable. The lifting mechanism is not shown in the diagram.

[0031] In this embodiment, the first clamping block 6 is frustum-shaped, and its cross-sectional diameter is smaller the smaller the distance from the second clamping block 7. The first clamping block 6 is placed at the mouth end of the glass bottle 5, and its special shape facilitates insertion into the bottle mouth, increases the contact area, and ensures stable clamping.

[0032] In this embodiment, the second clamping block 7 is cylindrical and is placed at the bottom of the glass bottle 5. Its entire circular surface is in contact with the bottom surface of the glass bottle 5 to ensure stable clamping.

[0033] In this embodiment, both the first clamping block 6 and the second clamping block 7 are made of rubber, which is slightly soft and provides better clamping force while protecting the bottle from damage.

[0034] In this embodiment, the first clamping block 6 and the second clamping block 7 are on the same axis.

[0035] like Figure 3As shown, the drive assembly includes: a dual-head motor 10 housed within the chassis 1; two transmission rods 11 located at the two output ends of the dual-head motor 10; a second synchronous pulley 12 mounted on each of the two transmission rods 11; a synchronous belt 13 mounted on each of the second synchronous pulleys 12; and the second synchronous pulleys 12 driving the first synchronous pulley 9 to rotate via the synchronous belt 13. The dual-head motor 10 synchronously drives the second synchronous pulleys 12 at both ends to rotate, and through the linkage of the synchronous belt 13 and the first synchronous pulleys 9, it synchronously drives the glass bottle 5 to rotate from both ends.

[0036] like Figure 4 As shown, a limiting groove 14 is formed on the surface of the second connecting rod 71, and a limiting rod 15 is provided in the limiting groove 14. Slots matching the limiting rod 15 are formed on the inner walls of the rolling bearings on the first synchronous pulley 9 and the mounting plate 8. The second connecting rod 71 is slidably connected to the inner walls of the rolling bearings on the first synchronous pulley 9 and the mounting plate 8 via the limiting rod 15. A limiting screw 16 is provided on the upper surface of the limiting rod 15, and the lower end of the limiting screw 16 abuts against the inner wall of the limiting groove 14. The length of the first connecting rod 61 is less than that of the second connecting rod 71. The second clamping block 7 moves along the axial direction of the second connecting rod 71. The cooperation of the limiting groove 14 and the limiting rod 15 allows the second connecting rod 71 to rotate synchronously with the rolling bearings on the first synchronous pulley 9 and the mounting plate 8. The use of the limiting screw 16 allows the relative position between the second connecting rod 71, the first synchronous pulley 9, and the mounting plate 8 to be adjusted. In other words, the position of the second clamping block 7 is adjustable, which is convenient for stress testing of glass bottles 5 of different sizes.

[0037] In use, the bottle opening of the glass bottle 5 is first positioned with the first clamping block 6 facing it, and the first clamping block 6 is inserted into the glass bottle 5, keeping the glass bottle 5 parallel (at this time, the limiting screw 16 is loose and does not abut against the limiting groove 14). Then, the second clamping block 7 is pushed towards the glass bottle 5 to make close contact, and the limiting screw 16 is tightened to complete the clamping of the glass bottle 5. Afterwards, when stress testing of the glass bottle 5 requires rotating the bottle body, the dual-head motor 10 is started, driving the transmission rods 11 at both ends to rotate a certain angle. This, in turn, through the linkage of the second synchronous pulley 12, the synchronous belt 13, and the first synchronous pulley 9, causes the first connecting rod 61 and the second connecting rod 71 to rotate synchronously by a certain angle. This ensures that the first clamping block 6 and the second clamping block 7 drive the glass bottle 5 to rotate by a certain angle. Technicians do not need to manually rotate the glass bottle 5 when conducting a comprehensive stress test, and the rotation speed is constant and controllable.

[0038] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
