Problems solved by technology

[0002] Many products have to undergo mechanical impact tests. For small-weight impacts, the cage of the hammer is required to be light in weight, strong in strength, fixed in weight, easy to disassemble, and released suddenly when falling from a certain height. Currently, the mechanical release hammer device, The method of stacking and fixing the weights is inconvenient
[0003] At present, the well-known technology in China adopts the method of freely placing or position-limiting the weight of the hammer, which has an impact on the impact result when the body falls freely; the falling of the hammer is limited by the rolling method of the wheel, and the movement is relatively large when falling; the structure of the mechanical release device Complicated and inconvenient to operate

Embodiment Construction

[0013] When performing the mechanical shock resistance test, the figure 1 Among them, the T-shaped cage (9) locks and fixes the weight group (3) through the column (4) and the lock nut (7). The hammer structure is formed; the plate on the T-shaped cage is attracted to the electromagnet (5), and the hammer is lifted or released through the electromagnet (5); the hammer structure is placed on the linear guide rail ( 1) Move up. For the structure of weights, see image 3 , the two notches are suitable for inserting into the two uprights (4), and are finally fixed on the bottom tray of the cage by the lock nut (7). The T-shaped cage (9) is provided with reinforcing ribs (6) and (10) at the stressed upper and lower joints, and lightening holes (2) and (12) are set at the unstressed web.

Abstract

The invention discloses a weight-adjustable impact device, which is mainly used for performing a mechanical impact test on a product. Raised by a certain impact height, an impact hammer impacts or acts on an impacted object. A vertical guide rail is arranged on both sides of a T-shaped cage of the impact hammer so as to move the impact hammer up and down; a group of weight sets is fixed on the cage through an upright post and a lock nut; and the impact hammer is elevated through actuation of an electromagnet on the impact hammer and released by electric power shutdown so as to finish an impact action.

Description

technical field [0001] The invention relates to a mechanical impact test device, in particular to a free-fall impact device. Background technique [0002] Many products have to undergo mechanical impact tests. For small-weight impacts, the cage of the hammer is required to be light in weight, strong in strength, fixed in weight, easy to disassemble, and released suddenly when falling from a certain height. Currently, the mechanical release hammer device, Weight accumulation mode, fixed mode etc. are all more inconvenient. [0003] At present, the well-known technology in China adopts the method of freely placing or position-limiting the weight of the hammer, which has an impact on the impact result when the body falls freely; the falling of the hammer is limited by the rolling method of the wheel, and the movement is relatively large when falling; the structure of the mechanical release device Complicated and inconvenient to operate. Contents of the invention [0004] In...
