Description
Technical Field
[0001] The utility model relates to the technical field of sole detection tooling, in particular to a sole curvature detection device. Background Art
[0002] At present, the sole needs to be tested for curvature after it is produced by a mold. The sole is formed by integral injection molding so that if there is any curvature, the curvature of the sole can be determined by testing the curvature of the bottom surface of the sole. The curvature test can be used to verify whether the sole produced by the mold is compliant with the standards, thereby ensuring that the subsequent mold can mass-produce the soles, or to perform sampling inspection on the prepared soles during subsequent mass production to ensure that the soles are compliant with the standards. In the prior art, the curvature of the sole is mostly tested by medium and large equipment, or manually by tools such as rulers or protractors. The detection efficiency of medium and large detection equipment is slow, the cost of medium and large equipment is too high, and it occupies more space in the factory. The measurement efficiency of manual measurement is slow and the measurement accuracy is prone to errors. Utility Model Content
[0003] In view of the shortcomings of the prior art, the utility model provides a sole curvature detection device to solve the problem that the prior art lacks a detection tool for quickly detecting the curvature of the sole.
[0004] To achieve the above-mentioned purpose, the utility model provides a sole curvature detection device, including a detection platform, a groove for accommodating a sole to be detected from the outside world, fixing members for abutting against the periphery of the sole to be detected from the outside world and fixing the sole are provided on the inner walls on both sides of the groove, a plurality of grooves are provided on the bottom wall of the groove along the long diameter direction of the groove, and the plurality of grooves are distributed along the wide diameter direction of the groove, a linkage shaft is slidably provided in each of the grooves, a sliding shaft is slidably provided at the starting end of each of the linkage shafts along the axial direction of the linkage shaft, a roller for contacting the bottom surface of the sole to be detected from the outside world is movably provided at the starting end of the sliding shaft, the end of the sliding shaft is clearance-matched with the starting end of the linkage shaft, and a detection member for detecting the spacing between the sliding shaft and the linkage shaft when the movable position of the roller changes is provided between the sliding shaft and the linkage shaft, a driving member and a control module for driving the plurality of linkage shafts to move synchronously in their respective corresponding grooves are provided on the detection platform, and the driving member and the detection member are both communicatively connected to the control module.
[0005] The advantages of adopting the above technical solution are as follows: the operator places the sole to be tested in the groove and contacts the outer wall of the sole to be tested through the fixing member, so as to fix the sole to be tested in the groove. Then the operator controls the driving member to start through the control module, so that the driving member drives several linkage shafts to move synchronously in their respective grooves. The movement of the linkage shaft drives the sliding shaft to move along the direction of the groove opening. The movement of the sliding shaft drives the roller to move, and the roller contacts the bottom surface of the sole, so that the roller is relative to the sole to be tested. The bottom surface rolls, and the sliding shaft can slide along the axis direction of the linkage shaft, so that when the roller rolls on the bottom surface of the sole along the length direction of the sole, it will drive the sliding shaft to move along the axis direction of the linkage shaft along the amplitude of the bottom surface of the sole. That is, if the radial section of the bottom surface of the sole is in the shape of an arc, the rolling of the roller will drive the sliding shaft to move along the axis direction of the linkage shaft. When the linkage shaft moves from the beginning of the slot to the end of the slot, the movement trajectory of the end or beginning of the sliding shaft is adapted to the arc of the radial section of the bottom surface of the sole, so that the detection component can detect the distance between the sliding shaft and the linkage shaft, and detect The component detects the change of the sliding shaft position in real time and generates corresponding data to transmit to the control module. The control module receives the signal and generates a corresponding curve graph, that is, the corresponding curve graph is generated according to the change of the sliding shaft position with the movement of the linkage shaft. When the bottom surface of the sole is approximately horizontal, the numerical line in the curve graph generated by the control module is approximately horizontal. If the bottom surface of the sole has a certain curvature, that is, when the radial cross-section of the bottom surface of the sole is in the shape of an arc, the numerical line in the curve graph generated by the control module is arc-shaped, so as to determine the curvature of the sole to be detected according to the curve graph; through the setting of the above-mentioned technology, the operator can realize automatic detection and data presentation by putting the sole to be detected, the whole detection process is efficient and accurate, and the accuracy of the detection result is improved. At the same time, the cost of the whole tooling is too low and the space occupies less, which meets the needs of small and medium-sized enterprises; the control module in the above-mentioned technology is an existing technology, which can be a computer, an intelligent industrial control integrated machine and other equipment, and a display screen component can also be set to feedback the curve graph in real time. Because it is an existing technology, its specific method of generating the curve graph and its structural components are not described in detail.
[0006] The utility model is further configured as follows: a sliding hole is opened at the starting end of the linkage shaft along the axial direction of the linkage shaft, the end of the sliding shaft is slidingly arranged in the sliding hole, the detection component includes a distance sensor arranged at the bottom of the sliding hole, the detection end of the distance sensor is arranged toward the end face of the end of the sliding shaft, the diameter of the sliding hole is adapted to match the diameter of the sliding shaft, and the distance sensor is communicatively connected to the control module.
[0007] The benefits of adopting the above technical solution are: when the roller rolls on the bottom surface of the sole, it will drive the sliding shaft to move downward due to the amplitude of the bottom surface of the sole. When the sliding shaft moves downward, the position of the end of the sliding shaft in the sliding hole changes. At this time, the distance sensor detection end can record the distance between the end of the sliding shaft and the distance sensor detection end and generate corresponding data. When the linkage shaft slides from the beginning of the slot to the end of the slot, the distance sensor detection end will record and generate a number of data, that is, as long as the position of the end of the sliding shaft in the sliding hole changes, the distance sensor generates spacing data once, and the number of data is transmitted to the control module. The control module first generates a bar graph according to the number of data, that is, a spacing bar graph, and then generates corresponding vertices according to the top of each column in the bar graph. By connecting the vertices in sequence, a curve graph can be generated. The control module can optimize the curve graph to determine whether the bottom surface of the sole is a plane or a curved surface, so as to detect the curvature of the sole. The distance sensor in the above technology is a prior art, so its structure and function will not be described in detail.
[0008] The utility model is further provided with: a connecting ring is provided on the outer peripheral wall of the sliding shaft, and a return spring is connected between the end surface of the starting end of the linkage shaft and the connecting ring.
[0009] The benefits of adopting the above technical solution are: in the above technology, a return spring is connected between the linkage shaft and the connecting ring, so that when the sliding shaft is pressed downward in the direction of the linkage shaft by the influence of the roller, the return spring is compressed and deformed and generates a certain mechanical force acting on the sliding shaft, and the sliding shaft transmits part of the force to the sole through the roller, thereby ensuring a stable connection between the roller and the sole, avoiding the existence of a gap between the roller and the sole that affects the detection accuracy, and at the same time, the sliding shaft can be driven to reset by the return spring when the roller no longer presses down the sliding shaft, thereby avoiding the sliding shaft not being reset and causing the roller to not contact the sole, thereby avoiding the detection accuracy being affected.
[0010] The utility model is further provided with: an operating cavity is provided in the detection table, a number of the slots are connected to the operating cavity, a slide plate is slidably provided in the number of the slots, each of the slide plates is connected to a respective adjacent linkage shaft, the linkage shaft is vertically provided to the slide plate, a mating groove is connected between adjacent slots, a mating gear is movably provided in the mating groove, mating teeth are provided on both side walls of the slide plate along the length direction of the slot, each of the mating gears is meshed with the mating teeth on both sides thereof, the driving member comprises an electric push rod provided in the operating cavity, and an output end of the electric push rod is connected to any one of the slide plates.
[0011] The benefits of adopting the above technical solution are: in the above technology, when it is necessary to drive the linkage shaft to move, the electric push rod starts and pushes the skateboard connected to it to slide in the corresponding groove. Because the mating teeth on both sides of the skateboard are respectively engaged with the respective adjacent mating gears, the skateboard will drive the adjacent skateboards to slide synchronously when it moves, that is, the sliding direction of each skateboard is opposite to the sliding direction of the adjacent skateboard. The linkage shaft can be set at the beginning or the end of the skateboard according to the detection requirements, so as to ensure that the linkage shaft on each skateboard can move along the length direction of the sole when several skateboards move; in the above technology, multiple skateboards with different sliding directions are used to generate data with different directions but similar motion trajectories, so as to improve the detection range and detection accuracy; the electric push rod in the above technology is a prior art and therefore it will not be described in detail.
[0012] The utility model is further configured as follows: a plurality of fixing grooves are provided on the detection platform, a plurality of the fixing grooves are arranged on both sides of the containing groove and a plurality of the fixing grooves are connected to the containing groove, a fixing head is slidably arranged in each of the fixing grooves, a starting end of the fixing head is abutting end for abutting against the side edge of the sole to be detected outside, a force spring is connected between the end of the fixing head and the inner wall of the fixing groove, and the fixing head is the fixing part.
[0013] The advantages of adopting the above technical scheme are: before the sole to be tested is placed in the receiving groove, the operator can move the fixed head so that the abutting end of the fixed head retracts into the fixed groove, and then puts the sole to be tested in without moving the fixed head, so that the fixed head is driven by the force spring to reset and buckle on the side of the sole to be tested, and the sole to be tested is fixed by a number of fixed heads on both sides of the sole to be tested, so as to achieve stable placement of the sole to be tested in the receiving groove, ensuring that the sole to be tested will not shake or shift during the detection process, resulting in the detection accuracy being affected; in the above technology, a small electric push rod can be installed in the fixing groove without calculating the cost, and the movement of the fixed head can be achieved by the small electric push rod, that is, the movement mode of the fixed head is changed from manual to automatic through the setting of the small electric push rod, thereby improving the installation efficiency of the sole to be tested, thereby improving the detection efficiency.
[0014] The utility model is further configured that: a rubber pad is arranged at the beginning of the fixing head.
[0015] The benefit of adopting the above technical solution is that the provision of the rubber pad in the above technology prevents the fixing head from causing damage to the outer wall of the sole. BRIEF DESCRIPTION OF THE DRAWINGS
