[0004] It is difficult to manually pick up and install some large-sized test samples, and the installation position of some large test samples is in the middle of the test machine, so the test sample cannot be installed in the middle of the test machine by the vertical crane, and the test sample needs to be pulled obliquely by manpower and placed in the clamp position in the middle of the test machine, which is inconvenient to operate. UTILITY MODEL CONTENTS

[0005] In order to solve the above problems, the utility model provides a test machine auxiliary feeding device to improve the inconvenient installation of large test samples in the prior art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: a test machine auxiliary feeding device, comprising a mounting plate, a fixed rod is fixedly connected to the bottom outer wall of the mounting plate, a fixed table is fixedly connected to the bottom outer wall of the fixed rod, a rotating arm rotary shaft is fixedly connected to the front inner wall of the fixed table, an arm plate is rotatably connected to the outer wall of the rotating arm rotary shaft, a fork rotary shaft is fixedly connected to the right inner wall of the arm plate, an installation seat is rotatably connected to the outer wall of the fork rotary shaft, a fork body is detachably installed on the outer wall of the installation seat, and a clamping column is clamped to the upper end inner wall of the fork body.

[0007] Further description of the above technical scheme:

[0008] The fork body is two symmetrical fork plates, the narrow surface of the fork plate of the fork body is perpendicular to the fork rotary shaft, and a limiting hole is formed in the upper end inner wall of the fork body.

[0009] Further description of the above technical scheme:

[0010] The arm plate is provided with two blocks, and the two blocks are symmetrically arranged.

[0011] As a further description of the above technical solution:

[0012] The upper end inner wall of the mounting plate is provided with a through hole, and the mounting plate is fixed on the cross beam of the testing machine through screws.

[0013] The utility model has the advantages of the following beneficial effects:

[0014] 1. The auxiliary feeding device is convenient and labor-saving, has good stability, and has high installation efficiency. The fixing of the sample can be completed at one time, the process of installing the sample by overcoming the gravity of the sample by manual labor is replaced by the auxiliary feeding device, and the tester only needs to push the sample into the center position of the testing machine clamp.

[0015] 2. The sample is clamped in the middle of the fork body, and the sample can rotate around the fork rotary shaft to realize one-stage rotation. The arm plate can drive the fork rotary shaft to rotate around the rotating arm rotary shaft to realize two-stage rotation, thereby expanding the rotary surface of the fork body.
