DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figures 1 to 6 As shown, the present invention provides a multi-station synchronous push-pull force tester, including a base 1, a movable base 2, a test cylinder 3, a test base 4 and a clamping base 5. The base 1 is an overall strip structure, and a plurality of groups of slide grooves 11 are arranged side by side on the base 1. The movable base 2 is installed on the upper part of the slide groove 11 and moves along the length direction of the slide groove 11; a rotating base 21 is installed on the upper part of the movable base 2, and the test cylinder 3 is installed in the rotating base 21; the test base 4 is symmetrically arranged on the base 1 at both ends of the slide groove 11, and a driving rod 31 is arranged at the end of the test cylinder 3, and a clamping claw 51 is arranged on the clamping base 5, and the clamping base 5 is arranged at the end of the driving rod 31 and on the side of the test base 4 facing the slide groove 11.

[0027] The test of the workpiece is carried out on the upper part of the base 1. On the one hand, the movable seat 2 can slide on the slide groove 11, thereby changing its position so that the distance between it and the test seat 4 in the direction is adjusted according to the length of the workpiece; in addition, the test cylinder 3 can be flipped on the rotating seat 21 to change its direction so that it can be used in conjunction with the test seat 4 in different directions, so that more options can be provided when conducting specific tests.

[0028] Among them, a screw rod 13 is installed in the slide groove 11, a slider 22 is arranged at the lower part of the movable seat 2, a thread hole 24 is arranged on the slider 22, the slider 22 is stuck in the slide groove 11, and is fitted on the outside of the screw rod 13 through the thread hole 24; the screw rod 13 is driven by a servo motor embedded in the base 1.

[0029] The lead screw 13 drives the slider 22 to move, so as to change the position relationship of the moving seat 2, thereby achieving the purpose of adjusting the position of the test cylinder 3.

[0030] Among them, limiting belts 12 are symmetrically arranged on both sides of the slide groove 11, and limiting grooves 23 are symmetrically arranged at the lower part of the movable seat 2. The limiting grooves 23 are engaged with the limiting belts 12; the two ends of the limiting belts 12 are aligned with the two ends of the slide groove 11.

[0031] The setting of the limiting belt 12 enables the moving seat 2 to be stuck thereon through the limiting groove 23, thereby limiting the moving direction of the moving seat 2 and preventing it from deflecting, thereby ensuring the stability of the movement of the moving seat 2.

[0032] The upper portion of the limiting belt 12 is arranged as an inverted trapezoidal structure, and the upper portion of the limiting groove 23 is matched with an inverted trapezoidal groove.

[0033] The inverted trapezoidal structure enables the limiting belt 12 to be stuck in the limiting groove 23 and cannot be separated, and can only move in the axial direction.

[0034] Among them, one end of the test cylinder 3 is set to a semicircular structure, and the test cylinder 3 is connected to the output end of the rotating motor embedded in the rotating seat 21; a support plate 25 is set on the upper part of the movable seat 2, and the support plate 25 is set on both sides of the rotating seat 21; when the side of the test cylinder 3 is pressed on the support plate 25, the test cylinder 3 is in a horizontal state as a whole.

[0035] The rotating motor controls the rotation of the test cylinder 3, and the setting of the support plate 25 can provide support for the test cylinder 3 in use, so that it maintains its own horizontal state, thereby meeting the thrust or tension test requirements and ensuring the stability of the test environment.

[0036] The clamping seat 5 is symmetrically provided with a mounting plate 52, a sleeve 53 is provided on the opposite side of the mounting plate 52, a telescopic rod 54 is provided in the sleeve 53, and the clamping jaw 51 is fixedly connected to the telescopic rod 54. A clamping cylinder is provided in the sleeve 53, and the telescopic rod 54 is connected to the output end of the clamping cylinder; a clamping groove is provided in the clamping jaw 51, and the cross section of the clamping groove is a trapezoidal structure.

[0037] The arrangement of the sleeve 53 and the telescopic rod 54 pushes the clamping jaws 51 to close through the clamping cylinder, so as to test the workpiece between the two sets of clamping jaws 51 and ensure the clamping of the workpiece. At the same time, a trapezoidal clamping groove is also arranged in the clamping jaws 51. This shape of clamping groove can be used for test pieces of different calibers, thereby providing a wider range of applications.

[0038] The slide groove 11 is consistent with the length direction of the base 1 , and three slide grooves 11 are evenly arranged; the test seats 4 are arranged at both ends of the base 1 , and six groups of test seats 4 are symmetrically arranged.

[0039] The length directions of the slide groove 11 and the base 1 are consistent, and the length space of the base 1 can be fully utilized; when the three groups of slide grooves 11 are used at the same time, the test sockets 4 in different directions can be used alternately for testing, which can avoid interference between adjacent test pieces and can also intuitively see the test comparison situation; the slide groove 11 and the test socket 4 can be expanded and arranged according to the usage.

[0040] Among them, a testing method of a push-pull force tester performed synchronously at multiple stations includes the following steps:

[0041] Step 1: Adjust the position and orientation of the moving base 2 according to the length of the test piece and the test item;

[0042] Step 2: Adjust the clamping base 5 on the movable base 2 to make the clamping claw 51 clamp one end of the test piece;

[0043] Step 3: Adjust the clamping seat 5 on the corresponding test seat 4 so that the clamping claw 51 clamps one end of the test piece;

[0044] Step 4: Adjust the test cylinder 3 to work, and perform a thrust or tension test on the test piece by extending and retracting the drive rod 31.
