Description

Technical Field

[0001] This utility model relates to the field of automotive parts quality inspection technology, and more specifically, it relates to an automated testing device for the strength of steering wheel leather. Background Technology

[0002] In the automotive manufacturing and parts production sector, the quality of steering wheel leather directly affects the driver's comfort, safety performance, and the overall interior quality of the vehicle.

[0003] Traditional methods for testing the strength and elasticity of steering wheel leather mainly rely on manual stretching tests, which are inefficient due to the manual operation.

[0004] In actual manual tensile testing, the tensile force, speed, and direction may vary depending on the operator, making it difficult to precisely control these parameters and thus compromising the strength of the leather being tested.

[0005] Because the leather is placed on the testing equipment during the testing process, the operator needs to directly contact the leather and the testing equipment during placement, which may result in the operator's hand being pinched by the testing equipment, leading to low safety. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automated testing device for steering wheel leather strength that improves testing efficiency, accuracy and safety.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An automated testing device for the strength of steering wheel leather includes a base, a frame mounted on the base, and the frame positioned above and fixedly connected to the base.

[0009] The frame is equipped with an upper clamping component and a lower clamping component located below the upper clamping component. The upper and lower clamping components are symmetrically distributed, and the lower clamping component is slidably connected to the upper clamping component. Both the upper and lower clamping components are connected to the frame. The upper clamping component includes a support plate, a first cylinder, and an upper clamping plate.

[0010] Both the first cylinder and the upper clamping plate are positioned above the support plate. The output end of the first cylinder is connected to the upper clamping plate. There is a first compression space between the upper clamping plate and the support plate for placing the leather.

[0011] The lower clamping component includes a placement plate, a second cylinder, and a lower clamping plate.

[0012] The second cylinder and the lower clamping plate are positioned above the placement plate. The output end of the second cylinder is connected to the lower clamping plate. A second compression space for placing leather exists between the lower clamping plate and the placement plate.

[0013] The base contains a third cylinder and a drive rod. One end of the drive rod is connected to the output end of the third cylinder, and the other end passes through the base and is connected to the placement plate.

[0014] The present invention is further configured such that: a through hole is provided on the placement plate, and a rod is provided on the support plate, one end of the rod is connected to the support plate, and the other end passes through the through hole and is connected to the frame.

[0015] The present invention is further configured such that: a first groove is provided on both the upper clamping plate and the lower clamping plate, and a second groove is provided on both the support plate and the placement plate to cooperate with the first groove.

[0016] The present invention is further configured such that: a positioning hole is provided on the base for the drive rod to pass through.

[0017] The present invention is further configured such that a reinforcing column is fitted onto the drive rod, and the reinforcing column is fixedly connected to the drive rod.

[0018] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0019] Select a piece of leather from a steering wheel, place both sides of the leather in the first and second compression spaces respectively, and operate the first and second cylinders to press the leather tightly.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] like Figures 1 to 2 As shown, the automated steering wheel leather strength testing equipment includes a base 1, a frame 2 installed on the base 1, the frame 2 is placed above the base 1 and integrally formed with the base 1, the frame 2 is made of glass, and a receiving groove is opened on one side of the frame 2. An upper clamping member 3 and a lower clamping member 4 placed below the upper clamping member 3 are installed in the receiving groove. The upper clamping member 3 and the lower clamping member 4 are symmetrically distributed.

[0026] The upper clamping member 3 includes a support plate 301, a first cylinder 302, and an upper clamping plate 303. Both the first cylinder 302 and the upper clamping plate 303 are positioned above the support plate 301. The output end of the first cylinder 302 is connected to the upper clamping plate 303. A first compression space exists between the upper clamping plate 303 and the support plate 301, allowing the leather on the steering wheel to be placed within this space. Operating the first cylinder 302 pushes the upper clamping plate 303, causing it to move along the first compression space towards the support plate 301, carrying the leather with it. Finally, the leather is fixed within the first compression space through compression.

[0027] The lower clamping member 4 includes a placement plate 401, a second cylinder 402, and a lower clamping plate 403. The second cylinder 402 and the lower clamping plate 403 are positioned above the placement plate 401. The output end of the second cylinder 402 is connected to the lower clamping plate 403. A second compression space exists between the lower clamping plate 403 and the placement plate 401.

[0028] The leather on the steering wheel is placed in the second compression space. The second cylinder 402 is activated, pushing the lower clamping plate 403. The lower clamping plate 403, carrying the leather, moves along the second compression space towards the placement plate 401, thus fixing the leather within the second compression space through compression. At this point, the leather on the steering wheel is fixed between the upper clamping member 3 and the lower clamping member 4.

[0029] Both the upper clamping plate 303 and the lower clamping plate 403 are provided with a first groove 9, and both the support plate 301 and the placement plate 401 are provided with a second groove 10 that cooperates with the first groove 9. Through the first groove 9 and the second groove 10, the leather can be better stuck in the first groove 9 and the second groove 10 when the leather is squeezed, which makes it easier to clamp the leather.

[0030] The placement plate 401 has two through holes 7, and two rods 12 are installed on the top surface of the support plate 301.

[0031] One end of the rod 12 is fixed to the support plate 301, and the other end passes through the corresponding through hole 7 and is fixed to the frame 2. The base 1 has a positioning hole 8. The third cylinder 5 and the drive rod 6 are installed in the base 1. One end of the drive rod 6 is connected to the output end of the third cylinder 5, and the other end passes through the positioning hole 8 and is fixed to the bottom surface of the placement plate 401.

[0032] The third cylinder 5 is operated, which pushes the drive rod 6, causing the drive rod 6 to move the placement plate 401 up and down. During the up and down movement of the placement plate 401, the through hole 7 on the placement plate 401 also moves up and down along the rod 12, which can stretch the leather on the steering wheel. The drive rod 6 is fitted with a reinforcing column 11, which is integrally formed with the drive rod 6, thereby increasing the stability of the placement plate 401 when it moves up and down.

[0033] A retaining sleeve is fitted onto the rod 12, which is fixedly connected to the rod 12 and also fixedly connected to the base 1, further increasing the stability between the upper clamping member 3 and the base 1.

[0034] Working principle: Select a piece of leather from a steering wheel. First, place one side of the leather in the first compression space. Operate the first cylinder 302 to compress and fix the leather within the first compression space. Then, place the other side of the leather in the second compression space. Operate the second cylinder 402 to compress and fix the leather within the second compression space. At this point, the leather on the steering wheel is fixed between the upper clamping member 3 and the lower clamping member 4. Operate the third cylinder 5 to move the placement plate 401 up and down, allowing for the stretching and extension of the leather on the steering wheel. This enables the testing of the strength and toughness of the leather on the steering wheel. The first cylinder 302, the second cylinder 402, and the third cylinder 5 can automatically fix and stretch the leather on the steering wheel without manual operation. During the testing process, the operator does not need to directly contact the leather and the testing equipment, thereby improving testing efficiency, accuracy, and safety.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
