Description

Technical Field

[0001] The utility model belongs to the technical field of rubber ring production, in particular to a rubber ring tension testing device. Background Art

[0002] Rubber rings are simple rubber products, but they have a wide range of uses. They are elastic at room temperature, can produce large deformations under the action of external forces, and can return to their original shape after the external forces are removed. After being made, rubber rings often need to be stretched for performance testing.

[0003] For example, Chinese utility model CN218546343U discloses a rubber ring tension test fixture and a testing machine using the same. A groove is provided on the side wall of the suspension component for the rubber ring to sink into so as to limit the position of the rubber ring in the axial direction of the suspension component. The groove is provided to limit the position of the rubber ring, thereby reducing the risk of the rubber ring slipping and falling off during the stretching process. This not only ensures the test efficiency, but also avoids accidental injury to the operator.

[0004] However, existing production lines often produce rubber rings of various models and sizes. Inspection personnel need to conduct random inspections on rubber rings of various models. Existing suspension parts are fixed in size and have poor versatility. When the diameter of the rubber ring is small, a smaller suspension part needs to be replaced, which requires frequent replacement of suspension parts during the inspection process, resulting in low overall inspection efficiency.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0028] See also Figure 2 and 3 As shown, the utility model is a rubber ring tension testing device, comprising two frame members 1, the frame member 1 is connected to a testing machine, the frame member 1 is fixedly connected with a suspension member 2, the cross section of the suspension member 2 is a semicircular structure, so that the two suspension members 2 are spliced ​​into a cylindrical structure.

[0029] The suspension member 2 includes a plurality of suspension segments 201, three of which are shown in the figure as an example, and the diameters of the three suspension segments 201 decrease toward the end away from the frame member 1, so that two suspension members 2 are spliced ​​to form a stepped shaft structure.

[0030] A hanging groove 202 is formed on the circumferential surface of the hanging segment 201 , and the hanging groove 202 is located at the junction of the end surface and the circumferential surface of two adjacent hanging segments 201 .

[0031] The cross section of the hanging groove 202 is an arc-shaped structure, and is tangent to the end face of the adjacent hanging segment 201, so that when the rubber ring is hung, the end face of the hanging segment 201 can be used for limiting and positioning, so as to facilitate the rubber ring to be placed in the hanging groove 202. At the same time, the hanging groove 202 and the circumferential surface of the hanging segment 201 are transitioned by the inclined surface 203, so that the rubber ring can be better placed in the hanging groove 202.

[0032] like Figure 1 As shown, when a rubber ring 3 with a larger diameter needs to be tested, the rubber ring 3 can be suspended in a suspension groove 202 on a suspension section 201 with a larger diameter, so that the rubber ring 3 with a larger diameter can be quickly tightened, thereby reducing the distance that the test machine drives the frame member 1 to move and improving the detection efficiency.

[0033] like Figure 6 As shown, when the rubber ring 3 to be tested has a small diameter and cannot be hung on the hanging section 201 with a larger diameter, the hanging groove 202 on the hanging section 201 with a smaller diameter is selected. Thus, without replacing the hanging component 2, the rubber rings 3 of different sizes can be tested, which effectively improves the versatility of the hanging component 2 and avoids the need to frequently replace the hanging component 2 during the testing process, thereby greatly improving the overall testing efficiency.

[0034] At the same time, if Figure 1 , 4 As shown in FIG. 5 , the side wall of the frame member 1 is fixedly connected with a support rod 101, and the suspension member 2 is axially provided with a mounting groove 204 that cooperates with the support rod 101, so as to support the suspension member 2 through the support rod 101 and improve the overall structural strength.

[0035] Specifically, the upper surface of the support rod 101 is an arc-shaped structure, and the inner wall of the mounting groove 204 is an arc-shaped structure adapted thereto. The support rod 101 is inserted through the side wall of the frame member 1, and a fixing block 102 located above the support rod 101 is welded on the other side of the frame member 1, and the lower surface of the fixing block 102 is in contact with the support rod 101, and a connection groove adapted to the support rod 101 can be provided on the lower surface of the fixing block 102, and the fixing block 102 and the support rod 101 can be fixed by welding or connected and fixed by screws.

[0036] In addition, the support rod 101 is provided with a countersunk hole 103, and the countersunk hole 103 is a waist-shaped hole structure; the inner wall of the mounting groove 204 is provided with a threaded hole 205 corresponding to the countersunk hole 103, which is used to connect the support rod 101 and the suspension member 2 by screws.

[0037] After the suspension member 2 is fixed to the side wall of the frame member 1 at one end, the support rod 101 and the suspension member 2 are connected and fastened using screws, thereby improving the tightness of the connection between the support rod 101 and the suspension member 2, improving the supporting effect of the suspension member 2, and further improving the overall reliability and stability of use.
