Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, specifically a shell stress testing device for stable clamping. Background Technology

[0002] When an object deforms due to external factors (force, humidity, temperature field changes, etc.), internal forces are generated between the different parts of the object. The internal force per unit area is called stress. The stress perpendicular to the same cross section is called normal stress, and the stress tangential to the same cross section is called shear stress.

[0003] Before some components leave the factory, their stress resistance is tested. For example, some rectangular shells need to be clamped and fixed before the test. However, traditional clamping devices are not convenient for clamping the front, back, left, right and four sides of the shell at the same time, which is inefficient. Therefore, it is necessary to develop a shell stress testing device that can clamp it stably. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0006] A device for testing the stress of a clamped outer shell, comprising:

[0007] The test bench has two long clamping plates symmetrically arranged on the top. The two long clamping plates move relative to each other and are used to clamp and adhere to the left and right side walls of the outer shell body. The test bench is equipped with a drive assembly for driving the movement of the two long clamping plates.

[0008] The test bench has rotating plates on its top four sides. Short clamping plates are rotatably arranged on the side of the four rotating plates near the front and rear sides of the outer shell. The four short clamping plates are used to clamp and fit the left and right positions of the front and rear side walls of the outer shell. The rotating plates have an inclined slope on the side away from the short clamping plates. The ends of the two long clamping plates abut against the surface of the inclined slope.

[0009] As the two long clamping plates gradually approach and clamp the outer shell body, the ends of the long clamping plates move along the inclined slope and push the rotating plate to cause the short clamping plates to clamp and adhere to the front and rear side walls of the outer shell body.

[0010] As a preferred embodiment of the clamping and stable shell stress testing device of this utility model, the driving component includes a horizontally symmetrical sliding groove opened on the top of the test platform below the long clamping plate. Three sliding grooves are respectively provided on the left and right sides. A slider is slidably arranged in the groove of each sliding groove. The slider on the same side is fixed to the bottom of a long clamping plate.

[0011] As a preferred embodiment of the clamping and stable shell stress testing device of this utility model, the driving assembly further includes a screw rod rotatably disposed in a slide groove located in the middle, the two screw rods are collinear and the threads on the rods are opposite in direction, and the inner side of the remaining slide grooves is fixedly provided with a slide rod parallel to the screw rod, the rod body of the slide rod sliding through the side wall of the remaining slide blocks.

[0012] As a preferred embodiment of the clamping and stable shell stress testing device of this utility model, a transverse drive rod is rotatably provided in the middle of the left side wall of the test platform. The outer diameter of the screw is larger than the outer diameter of the drive rod. The two screws are collinear with the drive rod and fixed on the drive rod. A knob is provided at the left end of the drive rod.

[0013] As a preferred embodiment of the stable clamping shell stress testing device of this utility model, the long clamping plate is provided with a first anti-slip texture on the side near the shell body.

[0014] As a preferred embodiment of the clamping and stable shell stress testing device of this utility model, the top of the test platform is provided with a fixing plate around its perimeter. The fixing plate is located near the rotating plate and away from the short clamping plate and the inclined plane. A spring is provided on the side of the fixing plate near the rotating plate. The spring is always in a compressed state, and the other end of the spring abuts against one side of the rotating plate.

[0015] As a preferred embodiment of the stable clamping shell stress testing device of this utility model, the short clamping plate is provided with a second anti-slip texture on the side near the shell body.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: the outer shell body that needs to be clamped and stabilized is placed between two long clamping plates on the test bench. By turning the knob to drive the drive rod to rotate, the two long clamping plates will gradually move closer together, thereby clamping the left and right sides of the outer shell body. When the long clamping plates move, they will also slide along the inclined surface, pushing the rotating plate to rotate, so that the short clamping plate at the other end of the rotating plate gradually moves closer to the front and rear side walls of the outer shell body, clamping and stabilizing the front and rear side walls of the outer shell body. This achieves complete clamping and fixing of the outer shell body on all four sides, improving the stability of the outer shell body when it is clamped. Attached Figure Description

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] Please see Figures 1-6 The diagram shown is a structural schematic of an embodiment of the stress testing device for a securely clamped outer shell according to this utility model. Please refer to [link / reference]. Figures 1-6 This paper provides a detailed description of a stable shell stress testing device.

[0030] A stable shell stress testing device includes a test bench 100. Two long clamping plates 110 are symmetrically arranged on the top of the test bench 100. The two long clamping plates 110 move relative to each other and are used to clamp and adhere to the left and right side walls of the shell body 300. A driving assembly for driving the movement of the two long clamping plates 110 is provided on the test bench 100. A device for testing the shell stress is also provided on the test bench 100, which is not shown in the figure.

[0031] The test bench 100 has rotating plates 200 rotatably arranged around its top. Short clamping plates 210 are rotatably arranged on the side of the four rotating plates 200 near the front and rear sides of the outer shell 300. The four short clamping plates 210 are used to clamp and fit the left and right positions of the front and rear side walls of the outer shell 300. The rotating plates 200 have an inclined surface 240 on the side away from the short clamping plates 210. The ends of the two long clamping plates 110 abut against the surface of the inclined surface 240.

[0032] As the two long clamping plates 110 gradually approach and clamp the outer shell body 300, the ends of the long clamping plates 110 move along the inclined slope 240 and push the rotating plate 200 to drive the short clamping plates 210 to clamp and adhere to the front and rear side walls of the outer shell body 300. It should be noted that when the two rotating plates 200 at the front and rear positions are in a parallel state, when the two short clamping plates 210 at the front and rear positions are attached to the side walls of the outer shell body 300, the two short clamping plates 210 are in a parallel state and the distance between them is equal to the width of the outer shell body 300, that is, the distance between the front and rear side walls of the outer shell body 300.

[0033] Furthermore, the driving assembly includes symmetrical horizontal sliding grooves 120 formed on the top of the test bench 100 below the long clamping plate 110. Three sliding grooves 120 are provided on each side, and a slider 130 is slidably disposed within each groove 120. The sliders 130 on the same side are fixed to the bottom of the long clamping plate 110. The driving assembly also includes a screw 140 rotatably disposed within a middle sliding groove 120. Two screws 140 are collinear, and their threads run in opposite directions. The remaining sliding grooves 120 have sliding rods 150 fixedly disposed parallel to the screws 140. The rods 150 have... The sliding block 130 slides through the side wall of the remaining sliders. A transverse drive rod 160 is rotatably installed in the middle of the left side wall of the test bench 100. The outer diameter of the screw 140 is larger than the outer diameter of the drive rod 160. The two screws 140 are collinear with the drive rod 160 and fixed on the drive rod 160. A knob 170 is provided at the left end of the drive rod 160. The knob 170 facilitates the rotation of the drive rod 160. When the drive rod 160 rotates, it drives the two screws 140 to rotate simultaneously. Since the threads on the two screws 140 are opposite, they will drive the two long clamps 110 to gradually approach each other, thereby clamping the left and right sides of the outer shell body 300.

[0034] Furthermore, the long clamping plate 110 is provided with a first anti-slip texture 180 on the side near the outer shell body 300, which increases the friction between the long clamping plate 110 and the side wall of the outer shell body 300, thereby facilitating the clamping and securing of the outer shell body 300.

[0035] Furthermore, a fixing plate 220 is provided around the top of the test bench 100. The fixing plate 220 is located near the rotating plate 200 and away from the short clamping plate 210 and the inclined plane 240. A spring 230 is provided on the side of the fixing plate 220 near the rotating plate 200. The spring 230 is always under compression, and the other end of the spring 230 abuts against one side of the rotating plate 200. When the two long clamping plates 110 gradually move away from each other, until the long clamping plates 110 move to the outside of the inclined plane 240, the spring 230 will push one end of the rotating plate 200, so that the short clamping plate 210 at the other end moves away from the front and rear sides of the outer shell body 300, thereby releasing the clamping of the front and rear of the outer shell body 300.

[0036] Furthermore, the short clamp 210 is provided with a second anti-slip texture 250 on the side near the outer shell body 300, which increases the friction between the short clamp 210 and the side wall of the outer shell body 300, thereby facilitating the secure clamping of the outer shell body 300.

[0037] In practical use, the outer shell 300, which needs to be clamped securely, is placed between two long clamping plates 110 on the test bench 100. The drive rod 160 is rotated by the knob 170. When the drive rod 160 rotates, it drives the two screws 140 to rotate simultaneously. Since the threads on the two screws 140 are opposite, the two long clamping plates 110 will gradually move closer together, thereby clamping the left and right sides of the outer shell 300. When the long clamping plates 110 move, they will also slide along the surface of the inclined plane 240, pushing the rotating plate 200 to rotate. This causes the short clamping plate 210 at the other end of the rotating plate 200 to gradually move closer to the front and rear side walls of the outer shell 300, clamping and securing the front and rear side walls of the outer shell 300. This achieves complete clamping and fixing of the outer shell 300 on all four sides, improving the stability of the outer shell 300 when clamped.

[0038] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
