[0020] The core of the present invention is to provide a zipper strength testing machine, including multiple types of lower clamps, one of which can be moved to a working position to align with the upper clamp assembly, and is used for testing different parts of the zipper. There is no need to frequently replace the clamps, thereby improving work efficiency.

[0021] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Please refer to Figures 1 to 3 , Figure 1 A schematic structural diagram of a specific implementation of the zipper strength testing machine provided by the present invention; Figure 2 A schematic structural diagram of a lower clamp assembly in a specific implementation manner of the zipper strength testing machine provided by the present invention; Figure 3 This is a schematic structural diagram of an upper clamp assembly in a specific implementation manner of the zipper strength testing machine provided by the present invention.

[0024] The lower clamp assembly 2 includes a base and multiple types of lower clamps, the base is mounted on the frame 1, and multiple types of lower clamps are mounted on the base, that is, multiple lower clamps are arranged on the base, each lower clamp has a different structure, so as to clamp different parts of the zipper, and the base can drive one of the multiple lower clamps to move to a working position to align with the upper clamp assembly 3. The upper clamp assembly 3 includes a top seat and multiple types of upper clamps, the top seat is mounted on the frame 1, and multiple types of upper clamps are mounted on the top seat, that is, multiple upper clamps are arranged on the top seat, each upper clamp has a different structure, so as to clamp different parts of the zipper, and the top seat can drive one of the multiple upper clamps to move to a working position to align with the lower clamp located at the working position.

[0025] During the inspection process, select the specific upper and lower clamps corresponding to the parts to be inspected, the base drives the lower clamp to move to the working position, and the top seat drives the upper clamp to move to the working position, that is, the upper and lower clamps corresponding to the parts are aligned, and the parts to be inspected are clamped by the upper and lower clamps, and then strong inspection is performed. When inspecting different parts, the base and the top seat are driven to make different upper and lower clamps simultaneously in the working position and then align them for inspection. The working position means that the upper and lower clamps are opposite to each other, and the parts to be inspected clamped here can complete normal inspection work.

[0026] The multiple different types of fixtures required in the process of testing multiple parts of zippers are integrated into one. During the testing process, you only need to switch the parts to be tested to the working position. There is no need to replace the fixtures in the process of completely testing all the strength coefficients of a zipper. There is no need to frequently remove and install fixtures on the strength testing machine, which avoids detection errors, reduces labor intensity and improves work efficiency.

[0027] In the zipper strength testing machine provided in the specific embodiment of the present invention, the base and the top seat can adopt various structural types, the base includes a steering seat 21 and a turntable 22, the steering seat 21 is fixedly connected to the frame 1, the turntable 22 is arranged horizontally, and a rotating shaft coinciding with the central axis of the turntable 22 is arranged below the turntable 22, that is, the rotating shaft is arranged vertically, and the turntable 22 is installed above the steering seat 21 through the rotating shaft, and various types of lower clamps are sequentially installed on the outer peripheral edge of the upper surface of the turntable 22 and extend upward, and the turntable 22 can rotate around its own central axis to drive one of the multiple lower clamps to move to the working position. The connection line of multiple lower clamps forms a circle, and the working position is located at a certain point of this circle. When working, the turntable 22 is rotated to move each lower clamp to the determined point of the working position in turn.

[0028] The top seat includes a slide rail 31 and a plurality of sliders 32. The slide rail 31 is fixedly connected to the frame 1. The plurality of sliders 32 are sequentially mounted on the slide rail 31. The various types of upper fixtures are respectively mounted below the plurality of sliders 32 and extend downward, that is, a slider 32 is arranged above each upper fixture to connect to the slide rail 31. The slider 32 can slide along the slide rail 31 to drive one of the various upper fixtures to move to a working position. The working position is located at a certain point of the slide rail 31. When working, the slider 32 is moved to move each upper fixture to the determined point of the working position in sequence.

[0029] Since there are many lower clamps on the base, the turntable 22 is rotated to find the correct position, increasing the number of lower clamps that can be installed on the turntable 22. The rotation method is conducive to speeding up the efficiency of selecting the lower clamps. There are fewer upper clamps on the top seat of the lower clamps, so the slide rail 31 is used to slide to find the correct position, simplify the operation steps, and improve stability. It is also possible to use circular motion for both the upper and lower parts, or linear motion for both the upper and lower parts, or other driving methods, such as the turntable is set vertically and the rotation axis is horizontal, all of which are within the protection scope of the present invention.

[0030] In order to improve the reliability and stability of the use of the equipment, it also includes a lower positioning member for fixing the position of the turntable 22 and an upper positioning member for fixing the position of the slider 32. Specifically, the lower positioning member includes a lower positioning bracket 23 and a lower positioning pin 24. The lower positioning bracket 23 is fixedly mounted on the steering seat 21, and the lower positioning pin 24 is movably mounted on the lower positioning bracket 23. The outer periphery of the turntable 22 is provided with lower positioning holes 25 corresponding to each lower clamp position, and the horizontally arranged lower positioning pin 24 can be inserted into the lower positioning hole 25. In the process of rotating the lower clamp, the lower positioning pin 24 is pulled outward, and the turntable 22 can rotate freely. When the lower clamp is rotated into place, the lower positioning pin 24 is facing one of the multiple lower positioning holes 25. The lower positioning pin 24 is inserted into this lower positioning hole 25 to realize the positioning of the turntable 22, so that it cannot rotate. When the lower clamp needs to be switched, the lower positioning pin 24 is pulled out and the above steps are repeated.

[0031] The upper positioning member includes an upper positioning bracket 33 and an upper positioning pin 34. The upper positioning bracket 33 is fixedly mounted on the frame 1, and the upper positioning pin 34 is movably mounted on the upper positioning bracket 33. The outer side of each slider 32 is provided with an upper positioning hole 35, and the upper positioning pin 34 arranged horizontally can be inserted into the upper positioning hole 35. In the process of moving the upper fixture, the upper positioning pin 34 is pulled outward, and the slider 32 can move freely in a straight line. When the upper fixture is moved into place, the upper positioning pin 34 is directly opposite to one of the multiple upper positioning holes 35. The upper positioning pin 34 is inserted into this upper positioning hole 35 to achieve the positioning of the slider 32, so that it cannot move. When the upper fixture needs to be switched, the upper positioning pin 34 is pulled out and the above steps are repeated. Other types of positioning devices can also be used, such as locking by friction, or positioning by ratchet, etc. Up and down drive devices, such as motors or hydraulic drive systems, can also be set to achieve automatic control of fixture switching.

[0032] In the zipper strength tester provided in the specific embodiment of the present invention, the multiple types of lower clamps include lower universal clamps 26, socket displacement clamps 27, single tooth displacement clamps 28, slider pull tab combination clamps 29 and latch displacement clamps 210 which are evenly distributed in sequence, and the multiple types of upper clamps include upper universal clamps 36 and hooks 37 which are sequentially arranged along the slide rail 31. The above-mentioned clamps can meet the strength test of zipper parts, and the types and quantities of the clamps can also be adjusted according to the situation.

[0033] On the basis of the zipper strength testing machine provided in the above-mentioned specific embodiments, a plurality of lower clamps are connected to the base through a plurality of lower support rods 211, that is, a lower support rod 211 is provided at the lower end of each lower clamp, and the lower ends of all lower support rods 211 are connected to the turntable 22, and the lengths of the lower support rods 211 are different, which are set and matched according to the different types of lower clamps installed at their upper ends, and a plurality of upper clamps are connected to the top seat through a plurality of upper support rods 38, that is, an upper support rod 38 is provided at the upper end of each upper clamp, and the upper ends of the plurality of upper support rods 38 are respectively connected to a plurality of sliders 32, and the lengths of the respective upper support rods 38 are different, which are set and matched according to the different types of upper clamps installed at their lower ends. Specifically, the lower support rods 211 and the upper support rods 38 are telescopic rods that can adjust their own lengths. Since the stiffness of different upper and lower fixture combinations is inconsistent, the height difference problem is solved by supporting rods. The corresponding combination heights of different items for multiple fixture tests are counted, and the corresponding support rod lengths are designed according to different heights. The support rods are directly connected to the upper and lower fixtures, and there is a fine adjustment of about 2cm up and down at the connection to eliminate the height difference adjustment problem between project test switching. Threaded rotation adjustment or sliding linear adjustment can be used.

This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core ideas of the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified in a number of ways, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
