Description

Technical Field

[0001] The utility model relates to the technical field of automobile bumpers, and in particular to a sample frame for detecting the length and size of the front and rear bumper body materials. Background Art

[0002] In the past, the length dimensions of the front and rear bumper body materials (before painting) were controlled by material inspection fixtures, weighing, and measuring key dimensions with vernier calipers.

[0003] However, it has many disadvantages: the product size can only be roughly controlled by weighing, and it is affected by the density fluctuation of the material batch, resulting in the product size requirements after painting still not being met; because the front and rear bumper body materials are plastic products, they have weak overall strength and are easy to deform. By weighing or measuring key dimensions with a vernier caliper to monitor the length of the front and rear bumper body materials, the error is about 0.8mm, and it is also difficult to control the product size; if the front and rear bumper body material inspection fixture is used to control the length of the front and rear bumper body materials, the inspection fixture needs to over-constrain the front and rear bumper body materials, resulting in the inspection fixture having a certain correction function on the product, and cannot effectively detect the length of the front and rear bumper body materials in a free state, and the inspection cycle is long, so it cannot truly reflect the product size.

[0004] The above detection methods cannot effectively measure the length dimensions of the front and rear bumper body materials, and thus it is difficult to ensure that the dimensions after painting are qualified. Utility Model Content
