Description

Technical Field

[0001] The utility model relates to the technical field of wire harness production, in particular to a portable cable tie tension tester. Background Art

[0002] In the manufacturing process of wire harnesses, cable ties are used to tighten wire harnesses and are one of the most commonly used accessories. Cable tie guns are special products that are produced and sold specifically for tying and tightening cable ties. The method of use is: take the self-locking cable tie, pass it through the tied object and insert it into the buckle, tighten it, insert the tail of the cable tie into the head of the opening of the cable tie gun, and press the tail on the cable tie gun with teeth. At this time, the head of the cable tie gun should support the cable tie buckle; hold the cable tie gun and hold the wrench to tighten the cable tie. The tightening force is determined by the gear position of the cable tie gun. When it is tightened to a certain extent, the cable tie will automatically lock, and then the cable tie will be automatically cut off with force to complete the cable tie locking operation.

[0003] At present, the following problems have been found in the use of cable ties: 1. Before using cable ties, they need to be batch inspected to ensure that their breaking force meets the use requirements; 2. After the cable tie gun has been used for a period of time, the set tension does not meet the requirements, and the tightening force of the cable tie gun needs to be tested and calibrated regularly; 3. Different cables have different corresponding tension parameter requirements. If the same cable tie gun is used, its tightening force needs to be tested and adjusted. The above tests are currently performed using a cable tie tension tester, but the existing cable tie gun tension tester is large in size, high in cost, and relatively complex to operate, which has a certain impact on work efficiency, measurement accuracy, and measurement cost.

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described below in combination with specific implementation methods. The drawings are only used for exemplary descriptions, and only show schematic diagrams rather than physical drawings, and cannot be understood as limitations of this patent; it is understandable to those skilled in the art that some well-known structures and their descriptions in the drawings may be omitted.

[0018] like Figure 1 , Figure 2 , Figure 3 As shown, the portable cable tie tension tester of the utility model comprises a bottom plate 1, a tension meter 2, a connection block 3, and a top block 4. The tension meter 2 is arranged on the bottom plate 1, and the screw end of the tension meter 2 is provided with a connection block 3. The connection block 3 is detachably provided with a cable tie seat 5. The front end of the cable tie seat 5 forms a cable tie hook 5-1 through a clearance groove 6. The cable tie hook 5-1 is provided with a first vertical opening groove 7 that runs through the front and rear sides thereof. The top block 4 is arranged on one end of the bottom plate 1 away from the tension meter 2. The top block 4 is provided with a second vertical opening groove 8 that runs through the front and rear sides thereof, and the second vertical opening groove 8 corresponds to the first vertical opening groove 7. Among them, the tension meter is a digital push-pull force meter, which can give a more intuitive tension value.

[0019] When testing the breaking force of a cable tie, first place the head of the cable tie in the slot of the cable tie holder, and let the body of the cable tie pass through the first vertical opening slot and the second vertical opening slot. Hold the cable tie gun or other workpiece to clamp the tail of the cable tie and pull it outward until the cable tie breaks. At this time, the value displayed on the dynamometer is the breaking force value of the cable tie. Whether the cable tie meets the use requirements can be judged based on the breaking force value. When testing the tightening force of the cable tie gun, first place the head of the cable tie in the slot of the cable tie holder, and let the body of the cable tie pass through the first vertical opening slot and the second vertical opening slot. The cable tie passes through the slot, and its tail is pressed on the cable tie gun with teeth. At this time, the head of the cable tie gun should be against the vertical surface of the front side of the abutment block. Start the cable tie gun to tighten the cable tie, and the force will be transmitted to the dynamometer along the cable tie. The dynamometer displays the tension data in real time. When the cable tie is tightened to the maximum, the cable tie is cut off. At this time, the peak value recorded by the dynamometer is the tightening force of the cable tie gun. Then, according to the measured tightening force, the gear of the cable tie gun is calibrated to make the gear correspond to its tightening force, or the gear of the cable tie gun is adjusted to get a relative optimal value for a specific cable tie.

[0020] In order to make the tester compact and easy to carry, the structure of the bottom plate is adapted to the size of the tensile gauge, connecting block and top block arranged on the top thereof. Specifically, the bottom plate 1 has a first rounded rectangular plate 1-1 and a second rounded rectangular plate 1-2 connected by an arc portion, and the width of the first rounded rectangular plate 1-1 is greater than that of the second rounded rectangular plate 1-2. The tensile gauge 2 is arranged on the first rounded rectangular plate 1-1 by bolts, and the top block 4 is arranged on the second rounded rectangular plate 1-2 by bolts. A through hole is provided on the second rounded rectangular plate for the positioning column to pass through, and a blind hole is provided at the bottom of the top block for the positioning column to pass through, thereby realizing the rapid positioning and fixing of the top block.

[0021] At the same time, in order to facilitate the abutment of the cable tie gun, the front side surface of the top block 4 is a vertical plane, and the front side surface of the top block 4 is flush with the front side surface of the bottom plate 1.

[0022] During the cable tie breaking force test, if the workpiece is held and clamped, it may tilt to the left or right when the force is applied. In order to ensure the accuracy of the test, a limiting groove 9 is provided on the bottom plate 1, and the connecting block 3 and the cable tie seat 5 are both movably arranged in the limiting groove 9 and are arranged in contact with the bottom surface of the limiting groove 9. This design allows the connecting block and the cable tie seat to only move forward and backward under force, but not left and right, thereby ensuring the accuracy of the test.

[0023] In this embodiment, the connection block and the cable tie seat are detachably arranged in this way, the top front end of the connection block 3 is provided with an L-shaped positioning portion 3-1, the horizontal plane of the L-shaped positioning portion 3-1 is provided with a threaded through hole 10, and the front side of the threaded through hole 10 is provided with a positioning blind hole 11 for the positioning column to pass through, the rear end of the cable tie seat 5 is formed with a fixing portion 5-2 adapted to the L-shaped positioning portion through the bottom L-shaped groove, the fixing portion 5-2 is provided with an inverted convex through hole 12 at a position corresponding to the threaded through hole 10, and a positioning through hole 13 at a position corresponding to the positioning blind hole 11, and the cable tie seat can be quickly and accurately placed on the connection block through the positioning column and bolts. The positioning column can realize the rapid positioning and connection of the cable tie seat, and the bolt passes from the inverted convex through hole to the threaded through hole of the connection block to realize the fixing of the cable tie seat and the connection block.

[0024] At the same time, in order to prevent the top block from being worn when the cable tie is tightened, thereby causing inaccurate force measurement, arc-shaped transition edges are provided on the upper and lower parts of the second vertical opening groove on the top block.

[0025] The above description is only the preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications, combinations and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the scope of the claims of the utility model.
