Description

Technical Field

[0001] The utility model relates to the technical field of heel shearing resistance detection tooling, in particular to a heel shearing resistance detection tooling. Background Art

[0002] At present, after the heels are prepared by mold processing, they need to be tested by heel testing tooling for various properties, including shear resistance, friction resistance, bending resistance and other tests. In daily life, heels are mostly subjected to gravity and partial shear force. During the daily use of high-heeled shoes, if the heels are subjected to high load impact, that is, high stress concentrated impact on a certain point of the heel, it is easy to cause damage to the heels. The high stress is generated by the user's own weight, walking method, external obstacles bumping or jamming the heels, etc. Therefore, the production and preparation of the heels need to meet the shear resistance requirements, and the shear resistance is the force that the structure can withstand when it withstands the shear force. Therefore, the shear resistance of the heels needs to be tested to ensure that the test requirements or the shear resistance requirements are met before the heels can be mass-produced. However, the prior art lacks an easy-to-operate heel shear resistance testing tooling to meet the needs of small and medium-sized enterprises. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a heel shear resistance detection tool to solve the problem that the prior art lacks a heel shear resistance detection tool that is easy to operate.

[0004] To achieve the above-mentioned purpose, the utility model provides a heel shear force detection tool, including a tooling table, on which a detection block and a driving block are relatively arranged, a linkage shaft is movably arranged between the driving block and the detection block, and a fixing piece for respectively fixing the tail end and the top end of the external heel to be detected is arranged at the starting end of the linkage shaft, the detection block is provided with a detection piece for contacting the outer wall of the middle end of the external heel to be detected and detecting the value of the force applied to the outer wall of the middle end of the heel to be detected in real time, and the driving block is provided with a driving piece for driving the linkage shaft to slide along the length direction of the tooling table and continuously applying force to the heel to be detected when the detection piece abuts against the middle end of the external heel to be detected.

[0005] The advantages of adopting the above technical solution are as follows: When it is necessary to detect the shear resistance of the heel, the tail end and the top end of the heel to be detected are fixed through the fixing member, and then the driving member drives the linkage shaft to slide along the length direction of the tooling table, so that the detecting member abuts against the middle part of the heel to be detected. At this time, the driving member continues to drive the linkage shaft to slide. When the detecting member abuts against the middle part of the heel to be detected, the heel to be detected can no longer move with the sliding of the linkage shaft. At this time, the driving member continuously applies a force to the heel to be detected through the linkage shaft, so that the middle part of the heel to be detected continuously presses the detecting member. And the acting position of this force is at the abutting position between the middle part of the heel and the detecting member. At this time, the detecting member can continuously detect the force output by the middle part of the heel to be detected and generate corresponding force data. This force data can be transmitted to an external intelligent control module or an intelligent control platform such as an industrial control computer, and the intelligent control platform sorts and analyzes this data. That is, during the continuous detection process of the detecting member, a number of force data will be output. The intelligent control platform arranges the number of force data in sequence according to the time line and makes a histogram. The intelligent control platform sets fixed points at the top of each columnar graph in the histogram, and connects a number of fixed points in sequence to form a curve graph. When the heel is not damaged, the force transmitted between the heel and the detecting member will gradually increase, that is, the curve shows a gradually rising trend at this time. When the heel is damaged or suddenly breaks, the force transmitted between the heel and the detecting member will instantaneously decrease or fluctuate, that is, the curve shows an instantaneous drop or a wavy shape at this time. So that the operator can know the force data corresponding to the time point when the curve shows an instantaneous drop by viewing this curve graph. This force data is the reference standard for the heel shear resistance; Through the setting of the above technology, the whole operation process is semi-automatic, including the automation of the data analysis process, thereby improving the operation efficiency and the detection efficiency. At the same time, through the above analysis and calculation, the generation of shear resistance data is realized, and the accuracy of the calculation result is improved. The whole tooling adopts simple test steps of driving, abutting and detecting, so as to improve the detection efficiency and meet the needs of small and medium-sized enterprises at the same time, and can efficiently detect heels of different categories; The intelligent control platform in the above technology is an existing technology, which can include existing technical components such as a display screen assembly, an intelligent chip, and a wireless transmission chip. Therefore, its structure and function will not be described in detail. Including the preparation of the above histogram and the curve graph are existing calculation methods and programming methods. Therefore, how to specifically prepare the histogram and the curve graph will not be described in detail.

[0006] The present utility model is further provided with: two connecting shafts are arranged at the starting end of the linkage shaft. The two connecting shafts are coaxially arranged and perpendicular to the linkage shaft. One of the connecting shafts extends an upper shaft towards the detection block, and the other connecting shaft extends a lower shaft towards the detection block. The upper shaft and the lower shaft are arranged opposite to each other, and a fixed gap for accommodating an externally to-be-detected shoe heel is formed between the upper shaft and the lower shaft. An upper hole for partially accommodating the top end of the externally to-be-detected shoe heel is formed at the bottom of the upper shaft, and a lower hole for partially accommodating the tail end of the externally to-be-detected shoe heel is formed at the top of the lower shaft. Through holes are formed on both the upper shaft and the lower shaft. The through hole on the upper shaft is communicated with the upper hole, and the through hole on the lower shaft is communicated with the lower hole. The fixing member includes two fixing bolts. The two fixing bolts are in one-to-one correspondence with the two through holes and are threadedly connected. The end of the fixing bolt is an abutting end for abutting against the outer wall of the externally to-be-detected shoe heel.

[0007] The advantages of adopting the above technical solution are as follows: When it is necessary to fix the to-be-detected shoe heel, the operator inserts the bottom of the shoe heel into the lower hole in a plug-in fit manner, so that the shoe heel and the lower shaft are kept relatively perpendicular. Then, the upper hole is inserted into the top of the shoe heel in a plug-in fit manner. After that, the operator screws in the fixing bolt so that the fixing bolt abuts against the outer wall of the shoe heel in a fit manner, thereby realizing the fixation of the top of the shoe heel in the upper hole and the fixation of the bottom of the shoe heel in the lower hole, and thus completing the fixation of the shoe heel, avoiding the deviation of the force application point caused by the shaking of the shoe heel during the test or the influence on the test result caused by the shaking.

[0008] The present utility model is further provided with: a plurality of connection holes are formed in the connecting shaft connected to the upper shaft along its height direction.

The starting end of the adjusting bolt is a connection end for passing through the through hole and being threadedly connected with any one of the connection holes.

[0009] The advantages of adopting the above technical solution are as follows: When installing the to-be-detected shoe heel, the operator can adjust the gap between the upper shaft and the lower shaft so that the gap adapts to the shoe heel, that is, when the bottom of the shoe heel is inserted into the lower hole in a plug-in fit manner and the bottom surface of the shoe heel abuts against the bottom wall of the lower hole, the operator moves the upper shaft so that the top wall of the upper hole abuts against the top surface of the shoe heel, thereby enabling the combination of the upper shaft and the lower shaft to clamp and limit the shoe heel. After the upper shaft is adjusted, the operator screws in the adjusting bolt so that the adjusting bolt passes through the through hole and is threadedly connected with the connection hole corresponding to the through hole, thereby realizing the position adjustment of the upper shaft on the connecting shaft, further adjusting the distance between the upper shaft and the lower shaft, so as to adapt to shoe heels of different sizes or types, and further improving the stability during shoe heel detection and the detection range for detecting different categories of shoe heels.

[0010] The present utility model is further provided with: both the upper hole and the lower hole are arranged in a circular hole shape or a square hole shape.

[0011] The advantages of adopting the above technical solution are as follows: in the above technology, both the upper hole and the lower hole are arranged in a round hole shape or a square hole shape to adapt to round heels or square heels, thereby improving the detection range.

[0012] The present utility model is further provided as follows: a detection groove is formed in the detection block, the opening of the detection groove is arranged towards the driving block, a force-bearing plate is detachably arranged in the detection groove, one end of the force-bearing plate is a matching end for abutting against the outer wall of the middle end of the heel to be detected outside, the detection member includes a pressure sensor embedded in the force-bearing plate, and the end face of the force-bearing end of the pressure sensor is flush with the end face of the matching end.

[0013] The advantages of adopting the above technical solution are as follows: when the heel contacts the force-bearing plate, the acting force transmitted by the heel will act on the force-bearing plate, and the pressure sensor is embedded in the force-bearing plate and the end face of the force-bearing end of the pressure sensor is flush with the end face of the matching end, so as to perform efficient and accurate force detection. In the above technology, the acting force between the heel and the force-bearing end of the pressure sensor is detected by the pressure sensor to generate the corresponding acting force value. At the same time, the force-bearing plate is detachably arranged in the detection groove, so that the operator can replace the force-bearing plates with different heights according to the position of the force application point required by the heel, thereby improving the detection range. At the same time, pressure sensors with different precisions can be replaced according to the detection requirements to improve the detection accuracy; the pressure sensor in the above technology is a prior art, and its force-bearing end is the detection end. Since it is a prior art, its structure and function will not be described in detail.

[0015] The advantages of adopting the above technical solution are as follows: in the above technology, the radial cross-section of the matching end of the force-bearing plate is arranged in a triangular shape or a semi-circular shape, so that the operator can replace the force-bearing plate according to the detection requirements. If it is necessary to increase the shear area, the force-bearing plate with a semi-circular radial cross-section is replaced. If it is necessary to concentrate the shear, the force-bearing plate with a triangular radial cross-section is replaced, so as to meet the detection requirements and improve the detection range and detection accuracy.

[0016] The present utility model is further provided as follows: the driving member includes an electric push rod arranged on the driving block, and the output end of the electric push rod is coaxially connected to the end of the linkage shaft.

[0017] The advantages of adopting the above technical solution are as follows: in the above technology, the linkage shaft is driven by the electric push rod to realize the movement of the heel to be detected. If it is necessary to load a larger force, the electric push rod can be replaced with a driving mechanism such as a loading cylinder. The electric push rod is a prior art, so its structure and function will not be described in detail. Description of the Drawings
