Description

Technical Field

[0001] The utility model relates to the field of impact tests, and particularly to an impact test device. Background Art

[0002] An impact test is a test method for determining how a material will change when subjected to an external impact or action, so as to determine the reliability of the material.

[0003] In the existing impact test device, under the action of the pendulum impact, after the material breaks, it sputters towards the other side, making the subsequent cleaning of the test more troublesome, and there is also a safety hazard that the fragments may cause harm to personnel; in addition, when manually operating, it is impossible to conveniently set the corresponding fixed position or reference point, and it is easy to cause a deviation in the starting position of the pendulum, resulting in a large error.

[0004] Therefore, it is very necessary to seek an impact test device that is stable and reliable, has a simple structure, low manufacturing cost and is easy to clean. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an impact test device, which can conveniently clean the fragments of the sample to be tested, and can also prevent the safety hazard of fragment sputtering and reduce the deviation caused by manual operation.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An impact test device includes a base; a support rod is arranged on the inner side of the base; an impact device is arranged on the outer side of the support rod, and the impact device is used for impacting the sample to be tested; a positioning device is arranged on the outer side at the top of the support rod, and the positioning device is used for calibrating the initial state of the impact device; two fixing devices are arranged on the base, and the fixing devices are used for fixing the sample to be tested; a collector is arranged on one side of the base, and the collector is used for collecting the sputtered fragments of the sample to be tested.

[0008] Further, the positioning device includes a connecting rod, a longitudinal positioner, a positioning rod and a transverse positioner; the inner side of the connecting rod is fixedly connected to the top of the support rod; the outer side of the connecting rod is fixedly connected to the upper end of the longitudinal positioner; the longitudinal positioner is provided with a slideway from top to bottom; the positioning rod is placed in the slideway and can move; the transverse positioner includes a fixing column, a sliding block, four transverse rods and a first bolt; the fixing column is arranged on the base; the sliding block is slidably sleeved on the fixing column; one end of the transverse rod is arranged on the sliding block in a matrix distribution, and the other end of the transverse rod is perpendicular to the longitudinal positioner and extends out from both sides of the longitudinal positioner; the positioning rod is horizontally placed between the transverse rods, and the up-and-down swing of the positioning rod is restricted by the transverse rods; the first bolt penetrates through the sliding block and its inner end is threadedly connected to the fixing column.

[0009] Further, the impact device includes a rotating rod, a transmission rod, and a small ball; the inner side of the rotating rod is connected to the middle end of the support rod by a bearing, and the outer side of the rotating rod is fixedly connected to the upper end of the transmission rod; the small ball is arranged at the lower end of the transmission rod.

[0010] Further, a channel for the transmission rod and the small ball to pass through is provided between the two fixing devices; the fixing device includes a fixing block, a moving block, a second bolt, and a wing nut; the fixing block is fixedly arranged on the base; the moving block is slidably arranged on the base behind the fixing block; the second bolt passes through the fixing block and the moving block; the wing nut is sleeved on the end of the second bolt, and the distance between the fixing block and the moving block is adjusted by rotating the wing nut.

[0011] Further, the plane in which the transmission rod swings, the center of the ball of the small ball, and the center of the channel are in the same vertical plane.

[0012] Further, the collector is a hollow semi-circular arc.

[0013] Further, a scale is provided on the side wall of the longitudinal positioner, and the scale is used to directly read the indication.

[0014] Further, the widths of the front and rear ends of the collector are greater than the width of the base; the height of the top of the collector is greater than the top of the support rod.

[0015] After adopting the above technical solution, the utility model has the following beneficial effects:

[0016] 1. The utility model is provided with components such as a connecting rod, a longitudinal positioner, a positioning rod, and a transverse positioner, forming a positioning system, realizing effective limitation of the positioning rod, and improving the stability of the positioning rod. In addition, the scale on the side wall of the longitudinal positioner provides an intuitive reading, which helps to accurately adjust the position of the positioning rod; if there is a height difference in the positioning rods extending on both sides of the scale, it is convenient for the operator to discover the abnormality of the instrument; by leaning the small ball against the lower part of the positioning rod, the initial state manually released by the operator each time is the same, reducing the error caused by manual operation. This precise positioning method improves the accuracy and repeatability of the test results.

[0017] 2. The utility model is equipped with a collector, which is designed as a hollow semi-circular arc, located at the rear side of the base and connected to the base. This design can effectively collect the fragments generated during the impact test of the sample to be measured, avoiding the fragments from splashing to the surrounding area. The hollow semi-circular arc design enables the fragments to slide down along the arc surface to the bottom of the arc surface under the action of gravity, simplifying the cleaning work after the test and reducing the safety hazards caused by the flying of fragments.

[0018] 3. Through the mutual cooperation of the fixing block, moving block, second bolt and wing nut, the present utility model firmly fixes the sample to be tested on the base, preventing displacement during the impact process and increasing the safety of the test. At the same time, the channels between the fixing devices ensure the smooth passage of the transmission rod and the small ball. The positioning rod, the center of the small ball and the channel are kept in the same vertical plane, further ensuring the stability of the impact process.

[0019] 4. The impact test device of the present utility model has a compact and reasonable structural design. Each component, such as the base, support rod, impact device, positioning device, fixing device and collector, has a clear division of labor and works together synergistically. The overall device is stable and reliable, and the manufacturing cost is relatively low, meeting the principle of economic benefits. Brief Description of the Drawings
