Description
Technical Field
The invention relates to the field of auxiliary frame test tools, in particular to an auxiliary frame support pull-out force test tool.
Background
Chinese patent No. CN205593905U discloses a pull-out force test apparatus for pull-out force test between a hose and a hard tube. However, the test device has the following disadvantages: 1. the pull-out force test device is only suitable for pull-out force tests of hose and hard pipe connection modes of several common specifications of automobiles, and cannot be suitable for pull-out force tests of auxiliary frame supports of automobiles; 2. the device can not be connected and fixed with a conventional actuating cylinder connecting device and is only suitable for a tensile test bed.
Disclosure of Invention
The invention aims to overcome the defects in the prior art, and provides the auxiliary frame support pull-out force test tool which has the advantages of simple structure and strong device reliability and can meet the test requirements of auxiliary frame assemblies of different specifications.
The purpose of the invention is achieved by the following technical scheme: the auxiliary frame support pull-out force test tool mainly comprises a connecting rod and an actuating cylinder connecting device, wherein the head of the connecting rod is fixedly connected with the actuating cylinder connecting device, the tail of the connecting rod is inwards sunken to form a step surface, and a screw hole is formed in the step surface and is in threaded connection with an auxiliary frame assembly to be tested through a plurality of gaskets.
As a further technical scheme, the specification and the number of the gaskets can be adjusted according to the sizes of different auxiliary frame assemblies to be tested.
As a further technical scheme, the actuating cylinder connecting device can be fixedly connected with the actuating cylinder in the horizontal or vertical direction.
The invention has the beneficial effects that: the function of testing the tool by the pulling-out force of the auxiliary frame assembly support is realized, and the reliability of the tool is ensured; the structure is simple, and the function of testing the pulling-out force of the auxiliary frame support in the horizontal direction and the vertical direction can be realized; the pull-out force testing function of different sizes of openings of the swing arm mounting bracket of the auxiliary frame is realized; and the test is completed under the condition of ensuring the stability and the reliability of the tool by combining the range of the loading force.

Description of reference numerals: the device comprises a connecting rod 1, a step surface 1-1, a screw hole 1-2, an actuating cylinder connecting device 2, a gasket 3 and an auxiliary frame assembly 4.
Detailed Description
The invention will be described in detail below with reference to the following drawings:
example (b): as shown in the attached drawing, the auxiliary frame support pull-out force test tool mainly comprises a connecting rod 1 and an actuating cylinder connecting device 2, the head of the connecting rod 1 is fixedly connected with the actuating cylinder connecting device 2, the tail of the connecting rod 1 is inwards sunken to form a step surface 1-1, a screw hole 1-2 is formed in the step surface 1-1, and the step surface is in threaded connection with an auxiliary frame assembly 4 to be tested through a plurality of gaskets 3.
As a further technical solution, the specification and number of the gaskets 3 can be adjusted according to the sizes of the sub-frame assemblies 4 to be tested. The gasket 3 in this embodiment includes the following specifications and numbers: 2 pieces of 10mm thick, 2 pieces of 5mm thick, 2 pieces of 3mm thick, 4 pieces of 1mm thick, 2 pieces of 0.5mm thick, 2 pieces of 0.3mm thick, and 4 pieces of 0.1mm thick; through the combination of different specifications, can satisfy the test demand of most conventional sub vehicle frame, sub vehicle frame support opening size that can match is between 40mm ~ 80mm, and the matching precision is 0.1 mm.
As a further technical scheme, the actuating cylinder connecting device 2 can be connected and fixed with the actuating cylinder in the horizontal or vertical direction, so that the pulling-out force testing function of the auxiliary frame support in the horizontal or vertical direction is realized.
As an optimal technical scheme, the connecting rod 1 and the actuating cylinder connecting device 2 are fixed through welding, and a mode that two ends are welded simultaneously is adopted, so that the reliability of the tool is improved, the requirement of general pull-out force is met, and the fracture of a welding seam is prevented.
The working process of the invention is as follows: when the test is started, firstly, the gaskets 3 with corresponding specifications and quantity are selected according to the opening size of the auxiliary frame assembly 4 to be tested, then the connecting rod 1 on which the gaskets 3 are padded is fixedly connected with the auxiliary frame assembly 4 through the bolts, the horizontal or vertical direction of the actuating cylinder connecting device 2 is selected according to the test direction requirement to be fixedly connected with the actuating cylinder, and the actuating cylinder is started to start the test.
It should be understood that equivalent substitutions and changes to the technical solution and the inventive concept of the present invention should be made by those skilled in the art to the protection scope of the appended claims.
