Description

Technical Field

[0001] This utility model relates to the field of automotive plastic parts testing technology, and in particular to a tooling for measuring pull-out force tests. Background Technology

[0002] The use of plastic parts in automotive body structures is becoming increasingly widespread, primarily because plastic parts offer advantages over traditional metal parts, such as lighter weight, lower cost, and more flexible design. For example, plastic parts can replace metal parts in areas like car doors, window frames, and mudguards. This not only reduces the overall weight of the vehicle and improves fuel economy but also lowers the overall manufacturing cost.

[0003] Currently, most existing testing devices for automotive plastic parts can only perform tensile testing on plastic parts of a single size. This necessitates setting up different equipment when testing plastic parts of multiple sizes, which greatly increases research and development costs and hinders large-scale production, processing, and promotion. Utility Model Content

[0004] The purpose of this invention is to provide a tooling for measuring pull-out force, which can enable a single device to perform pull-out force testing on automotive plastic parts of different sizes, thereby reducing R&D and usage costs and facilitating large-scale production, processing, use, and promotion.

[0005] To achieve the above objectives, this utility model provides a tooling for measuring pull-out force tests, including a base frame, a controller mounted on the top right front side of the base frame, and an auxiliary mechanism;

[0006] The auxiliary mechanism includes a fixed plate, a first support plate, a first clamping plate, a first adjustable cylinder, a slide, a second support plate, a second clamping plate, a second adjustable cylinder, and a pulling device. The fixed plate is fixed to the right side of the base frame. The first support plate is fixedly connected to the fixed plate and located on the fixed plate. The first clamping plate is disposed above the first support plate and slidably connected to the fixed plate. The first adjustable cylinder is electrically connected to the controller and fixedly connected to the fixed plate. Its output end is connected to the first clamping plate and located on the top of the fixed plate. The slide is disposed on the left side of the base frame. The second support plate is fixedly connected to the slide and located on the slide. The second clamping plate is disposed above the second support plate and slidably connected to the slide. The second adjustable cylinder is electrically connected to the controller and fixedly connected to the slide. Its output end is connected to the second clamping plate and located on the top of the slide. The pulling device is disposed on the side of the base frame near the slide.

[0007] The controller is equipped with a touch screen and a warning light. The touch screen facilitates equipment operation and parameter setting, and simultaneously displays tensile force data. The warning light will flash red to indicate a malfunction.

[0008] The pulling device includes a linear guide rail, a slider, and a drive assembly. The linear guide rail is fixedly connected to the base frame and is located on both sides of the top of the base frame. The slider is slidably mounted on the linear guide rail and is connected to the slide block by bolts. The drive assembly is located on the left side of the base frame.

[0009] The drive assembly includes a hydraulic cylinder and a tension sensor. The hydraulic cylinder is fixed to the left side of the base frame. The tension sensor is connected to the output end of the hydraulic cylinder and the slide block, and is electrically connected to the controller. It is located on the side of the hydraulic cylinder closer to the slide block.

[0010] The auxiliary mechanism further includes a protective cover and a tail plate. The protective cover is fixedly connected to the base frame and is located on the left side of the base frame, and is fastened to the outside of the hydraulic cylinder; the tail plate is fixed to the tail of the protective cover.

[0011] This utility model discloses a fixture for measuring pull-out force. When testing the pull-out force of plastic parts, firstly, the pulling device is controlled to move the slide to the loading point near the fixed plate. The plastic part is placed on the first and second support plates. Then, the first and second adjustable cylinders are controlled to move the first and second clamping plates downwards to clamp the workpiece. Next, the pulling device is activated to perform pulling and force testing. The data is processed and calculated by the controller. Adjusting the adjusting nuts at the tails of the first and second adjustable cylinders allows for stroke adjustment, thereby adjusting the vertical position of the first and second clamping plates. This enables clamping and fixing of plastic parts of different thicknesses, allowing a single device to perform pull-out force testing on automotive plastic parts of different sizes. This reduces R&D and usage costs and facilitates widespread production, processing, and application. Attached Figure Description

The pulling device is disposed on the side of the base frame 101 near the slide 107. The fixing plate 103 is fixed to the base frame 101 by positioning pins and bolts, with the positioning pins and bolts arranged from bottom to top. The first support plate 104 is fixed to the fixing plate 103 by positioning pins and bolts. The front cylinder seat of the first adjustable cylinder 106 is fixed to the fixing plate 103 by bolts, and its output end is connected to the first clamping plate 105 by bolts with countersunk bolts. The top of the fixing plate 103 has symmetrical through holes, and T-shaped linear sliding bearings are installed in the holes to facilitate guiding and cooperating with the circular guide rods on both sides of the first clamping plate 105. Two magnetic ring switches are installed on the outer tie rod of the cylinder of the first adjustable cylinder 106 to detect the piston position.

The second support plate 108 is fixed to the slide 107 by positioning pins and bolts. The front cylinder seat of the second adjustable cylinder 110 is fixed to the slide 107 by bolts. Its output end is connected to the second clamping plate 109 by bolts. The bolts are countersunk. The top of the slide 107 is symmetrically provided with through holes. T-shaped linear sliding bearings are provided in the holes to facilitate guiding and cooperating with the circular guide rods on both sides of the second clamping plate 109. Two magnetic ring switches are provided on the outer pull rod of the cylinder of the second adjustable cylinder 110 to detect the piston position. The second adjustable cylinder 110 is electrically connected to the controller 102 by a cable. The pulling device is used for pulling and force detection.

[0022] Secondly, the controller 102 is equipped with a touch screen 111 and a warning light 112.
