The invention discloses an ejecting force testing device used for a jack. The device comprises a base, two guide posts, an ejecting plate, a traction type dynamometers and steel wire ropes, wherein the two guide posts are symmetrically arranged on the base; two through holes for the guide posts to run through are formed in the ejecting plate; the through holes are in one-to-one correspondence with the guide posts; the guide posts run through the corresponding through holes and are slidably connected with the inner walls of the corresponding through holes; blocking pieces adjustable along the length directions of the guide posts are arranged on the guide posts under the ejecting plate; first connecting parts for connecting the traction type dynamometers are symmetrically arranged at the bottom of the ejecting plate; second connecting parts for connecting the steel wire ropes are arranged on the base vertically corresponding to the first connecting parts; one end of each traction type dynamometer is fixedly connected with the corresponding first connecting part, and the other end of each traction type dynamometer is detachably and fixedly connected with the corresponding steel wire rope; one end, away from each traction type dynamometer, of the corresponding steel wire rope is fixedly connected with the corresponding second connecting part; and a fixed groove for fixing the jack is formed in the base vertically corresponding to the middle part of the ejecting plate. The device is simple in structure and accurate in measurement, and is applicable for different specifications of jacks.
Description
technical field [0001] The invention relates to the technical field of jack testing, in particular to a grinding device for processing automobile brake pads. Background technique [0002] Before the jack is used, its maximum rated jacking force must be tested. In the prior art, the frame structure is generally used to verify the maximum forehead output force. When testing jacks of different sizes, place a block between the jack and the base as needed, adjust the height of the jack, and make the piston extension of the jack close to the working state. The placement of pads makes the jack detection operation complicated, time-consuming and labor-intensive, and safety accidents are prone to occur. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a jacking force testing device for a jack. [0004] A jacking force testing device for a jack proposed by the present invention comprises: a ba...
