Description

Technical Field

[0001] The present invention relates to the field of component detection, and particularly to an industrial component torque detection device and method. Background Art

[0002] In modern industrial production, various mechanical equipment and products are assembled from a large number of components. The connection between these components is usually achieved by using fasteners such as screws, bolts, nuts, etc. The connection quality of the fasteners directly affects the performance, safety, and reliability of the entire equipment or product. And the connection quality of the fasteners depends to a large extent on whether the tightening torque reaches the preset standard value.

[0003] Among them, a screw is a tool that uses the physical and mathematical principles of the inclined plane circular rotation and friction of an object to gradually tighten the machine parts. In life, when installing or renovating something at home, screws are often chosen for fixation. However, sometimes the torque of the screw is unknown, and if too much force is applied, the screw may break in the wall. Therefore, it is essential to conduct quality inspection on screws before leaving the factory, and torque detection is one of the important links.

At the same time, the adjustment of the wooden board platform used in cooperation is also very inconvenient.

Detailed implementation manners

[0047] In the following description, numerous specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, some technical features well known to the art are not described to avoid confusion with the present invention.

[0048] The applicant believes that the feeding and discharging operations of traditional screw torque detection devices are not convenient enough and require manual assistance. At the same time, the adjustment of the wooden board platform used in cooperation is also very inconvenient. When the torque detection of a screw is completed, the wooden board platform cannot be adjusted in time, resulting in low detection efficiency.

[0049] Therefore, the applicant designs an industrial part torque detection device and method. Through the provided feeding and receiving component 2, automatic feeding and discharging are realized, and in cooperation with the movable clamping unit 3, the position of the wooden board platform is quickly adjusted without manual operation, which is fast and convenient, and greatly improves the efficiency of screw torque detection.

[0050] The industrial part torque detection device involved in the present invention mainly includes three components: a feeding and receiving component 2, a pushing and limiting component, and an adjusting and detecting component 5.

[0051] Among them, the feeding and receiving component 2 includes a bearing and supporting unit connected to the base 1 and having a predetermined working height and supporting force; a positioning unit placed on the working surface of the bearing and supporting unit and capable of performing corresponding limiting, feeding, and discharging operations. The pushing and limiting component includes a movable clamping unit 3 connected to the bearing and supporting unit and having a predetermined working distance from the positioning unit; an auxiliary limiting plate 4 connected to the movable clamping unit 3, having a predetermined working size, and provided with corresponding alignment through holes. The adjusting and detecting component 5 includes a supporting and positioning unit connected to the base 1, having a predetermined working length and supporting force, and capable of performing corresponding supporting and bearing operations; a detecting unit slidably connected to the supporting and positioning unit and capable of performing sliding adjustment operations within a predetermined range. The detecting unit is provided with a clamping detecting head 6, the clamping detecting head 6 is provided with a clamping groove having a predetermined working size, and a plurality of special-shaped clamping plates 7 are slidably arranged on the working surface; the working surface of the special-shaped clamping plate 7 is provided with serrated clamping grooves, and there are multiple such grooves. The multiple special-shaped clamping plates 7 are evenly distributed on the working surface of the clamping detecting head 6. An expandable cross clamping handle 8 is arranged in the clamping groove of the clamping detecting head 6. The expandable cross clamping handle 8 has a predetermined magnetic attraction, and an industrial camera is arranged on the working surface of the clamping detecting head 6. During the later operation process, the feeding and receiving of screws can be realized through the feeding and receiving component 2, the working position of the wooden board platform used in cooperation can be autonomously adjusted through the pushing and limiting component, and the autonomous clamping, detection, and subsequent placing and discharging of the screws to be tested can be realized through the detecting unit.

[0052] In a further preferred embodiment, three of the special-shaped clamping plates 7 are arranged on the working surface of the clamping detecting head 6, and the three special-shaped clamping plates 7 are distributed in a triangular array on the working surface of the clamping detecting head 6. During the later operation process, the head position of the screw to be detected is clamped by the multiple special-shaped clamping plates 7. Since the special-shaped clamping plate 7 is provided with serrated clamping grooves, the head clamping part of the screw to be detected can be firmly clamped. The expandable cross clamping handle 8 has been subjected to over-magnetization treatment and is connected to the clamping detecting head 6 through an expansion rod and is placed in the clamping groove of the clamping detecting head 6. The specific structure of the expandable cross clamping handle 8 can refer to the blade structure of a plum blossom screwdriver in the prior art, and how to perform magnetization treatment on the expandable cross clamping handle can also refer to the screwdriver treatment process in the prior art. All of the above are prior arts and will not be elaborated in this application. In a further preferred embodiment, the expandable cross clamping handle 8 and the expansion rod are threadedly connected. During the later operation process, the blade shape of the expandable clamping handle can be flexibly adjusted according to actual needs. For example, it can be replaced with a flat head, a star shape, or a hexagonal shape, etc., to be suitable for detecting different screws.

[0053] The load-bearing and supporting unit includes two components: a support frame 201 and a load-bearing plate 202. The support frame 201 is connected to the base 1, has a predetermined working size and supporting force, and can perform corresponding positioning and load-bearing operations; the load-bearing plate 202 is placed on the working surface of the support frame 201, has a predetermined working size and load-bearing space, and can perform corresponding load-bearing and limiting operations. A support with a predetermined load-bearing space is formed by the support frame 201 and the load-bearing plate 202 to facilitate corresponding connection support and load-bearing operations.

[0054] The positioning unit includes two components: a backing plate 203 and a positioning cylinder 204. The backing plate 203 is placed on the working surface of the load-bearing plate 202, has a predetermined working size and load-bearing space, and can perform corresponding connection and positioning operations. The positioning cylinder 204 is connected to the backing plate 203, has a predetermined working size, is hollow, and is provided with a limiting through-hole of a predetermined working size. In a further preferred embodiment, the backing plate 203 is slidably connected to the load-bearing plate 202, and both the backing plate 203 and the positioning cylinder 204 are multiple. During the later operation process, the working positions of the multiple backing plates 203 can be slidably adjusted to drive the corresponding working position adjustment of the multiple positioning cylinders 204, and thus corresponding alternative feeding can be realized. During the later operation process, only the screw to be tested needs to be placed at the limiting through-hole of the positioning cylinder 204 to hold the screw to be tested. That is, as long as it is ensured that the working size of the head of the screw to be tested is larger than the working size of the limiting through-hole provided in the positioning cylinder 204. At the same time, the size of the screw shank of the screw to be tested is smaller than the size of the limiting through-hole provided in the positioning cylinder 204, and thus the screw to be tested can be held by the positioning cylinder 204.

[0055] The movable clamping unit 3 includes two components: a connecting plate 301 and a clamping part. The connecting plate 301 is placed on the working surface of the load-bearing and supporting unit, has a predetermined working size and load-bearing space, and can perform corresponding load-bearing and connection positioning operations; the clamping part is placed on the working surface of the connecting plate 301, has a predetermined working size and elasticity, and can perform telescopic adjustment operations within a predetermined range, and is multiple and arranged in an array on the working surface of the connecting plate 301. In a further preferred embodiment, there are four groups of the movable clamping unit 3, and they are arranged in a pairwise symmetric manner, that is, the four groups of the movable clamping units are arranged in a rectangular array. During the later operation process, the four movable clamping groups 3 respectively abut against the four sides of the wooden board platform, and thus the limiting and fixing of the wooden board platform can be realized.

[0056] The clamping part includes three components: a fixed plate 302, a telescopic cylinder 303, and a clamping push plate 304. The fixed plate 302 is placed on the working surface of the connecting plate 301, has a predetermined working size and supporting force, and can perform corresponding positioning and carrying operations. The telescopic cylinder 303 is connected to the fixed plate 302, has a predetermined working size, and can perform telescopic adjustment operations within a predetermined range. The clamping push plate 304 is connected to the telescopic cylinder 303, has a predetermined working size, and can move the corresponding working position along with the telescopic adjustment of the telescopic cylinder 303. During the later operation process, the telescopic adjustment of the telescopic cylinder 303 drives the clamping push plate 304 to move the corresponding working position. Multiple telescopic cylinders 303 of multiple sets of the movable clamping units 3 cooperate pairwise and perform opposite operation operations respectively, so as to realize the flexible movement of the front, back, left, and right of the working direction of the wooden board platform, so as to screw the screws to be inspected into the wooden board platform, and then the torque detection of the screws to be inspected can be realized. In the actual operation process, the hardness and thickness of the wooden board platform can be flexibly adjusted according to actual needs. The function of the wooden board platform is to provide a detection platform for the screws to be inspected to be screwed into, and then the corresponding torque data can be collected.

[0057] The auxiliary limit plate 4 is connected to the connecting plate 301 through a positioning slide rail 401, is placed above the working position of the clamping part, and has a predetermined working space directly left with the clamping part. There are multiple positioning slide rails 401, and there is a predetermined working distance between the multiple positioning slide rails 401, and the overall working height of the positioning slide rail 401 is greater than the overall working height of the clamping part. In a further preferred embodiment, the auxiliary limit plate 4 has a predetermined working thickness, and the overall working size of the alignment through hole provided on the auxiliary limit plate 4 is adapted to the overall working size of the clamping detection head 6 and is greater than the clamping detection head. That is, the inner diameter of the alignment through hole provided on the auxiliary limit plate 4 fits the outer diameter of the clamping detection head 6. During the later operation process, when the central point of the clamping detection head 6 corresponds to the key limit of the alignment through hole provided on the auxiliary limit plate 4, the clamping detection head 6 can be started to perform the corresponding torque detection operation. During the detection process, the clamping detection head 6 extends into the alignment through hole provided on the auxiliary limit plate 4. Since the auxiliary limit plate 4 has a predetermined working thickness, the clamping detection head 6 can be correspondingly assisted and restricted after the clamping detection head 6 penetrates into the alignment through hole of the auxiliary limit plate 4, so that the clamping detection head 6 can be limited when screwing the screw to be inspected, and the phenomenon of the screw to be inspected slipping or tilting during the screwing process can be avoided.

[0058] The support and positioning unit includes two components: a support and positioning column 501 and an extended support plate 502. The support and positioning column 501 is placed on the working surface of the base 1, and there is a predetermined working distance between it and the material pushing and limiting assembly, enabling corresponding support and limiting bearing operations. The extended support plate 502 is slidably connected to the support and positioning column 501, has a predetermined working length and supporting force, and one end extends outside the support and positioning column 501.

[0059] The detection unit includes four components: a second telescopic cylinder 503, a connecting and positioning cover 504, a rotating motor 505, and a connecting and rotating wheel 506. The second telescopic cylinder 503 is placed on the working surface of the extended support plate 502, and its cylinder rod passes through the extended support plate 502 and has a predetermined telescopic property. The connecting and positioning cover 504 is connected to the cylinder rod of the second telescopic cylinder 503, is hollow and has a corresponding open end, and can adjust the working position accordingly following the telescopic adjustment of the second telescopic cylinder 503. The rotating motor 505 is placed in the hollow chamber of the connecting and positioning cover 504 and can provide a predetermined rotational driving force. One end of the connecting and rotating wheel 506 is connected to the rotating motor 505 through a transmission track and can perform corresponding rotational adjustment operations under the drive of the rotating motor 505; the other end is connected to the clamping connection head.

[0060] In a further preferred embodiment, the connecting and positioning cover 504 is hollow, and an external driving cylinder is provided inside. The cylinder rod of the external driving cylinder is connected to the connecting and rotating wheel 506 through a positioning table. During the later operation process, further telescopic adjustment can be performed through the external driving cylinder, thereby driving the rotating motor 505 and the connecting and rotating wheel 506 to adjust the working position further.

[0061] Based on the above industrial component torque detection device, the present invention proposes a detection method for an industrial component torque detection device, and the specific steps are as follows:

[0062] First, manually place the screw to be detected at the positioning cylinder 204, and place the wooden board platform required for auxiliary testing at the movable clamping unit 3; drive the extended support plate 502 to slide and adjust in the direction close to the positioning cylinder 204, driving the entire detection unit to move and adjust in the direction close to the positioning cylinder 204.

[0063] Next, the second telescopic cylinder 503 is started to extend, driving the positioning detection head 6 to move toward the direction close to the screw to be detected. At this time, the telescopic cross positioning handle is in an extended state. When the telescopic cross positioning handle contacts the screw to be detected, the second telescopic cylinder 503 stops extending.

[0064] Subsequently, the cross-shaped positioning handle 8 is retracted to magnetically align the screw to be inspected, and the second retractable cylinder 503 is retracted to lift the screw to be inspected, and the plurality of special-shaped positioning plates are synchronously slid and adjusted in the direction close to the screw to be inspected to limit the screw to be inspected;

[0065] Then, the extension support plate 502 is driven to be adjusted in the direction away from the positioning cylinder 204, and the detection unit is driven to be moved and adjusted as a whole again, and the sliding adjustment is made until the telescopic cross positioning handle 8 provided by the positioning detection head 6 corresponds to the center of the positioning through hole provided by the auxiliary limit plate 4; the second telescopic cylinder 503 is started to extend again, and the rotating motor 505 is started to drive the positioning detection head 6 to rotate synchronously, and the screw to be tested is tightened in the wooden platform, and the torque of the screw to be tested is tested;

[0066] Next, the above steps are reversed to place the screws after inspection into the positioning tube, and then the movable positioning unit 3 is activated to push and adjust the working position of the wooden platform;

[0067] Finally, repeat the above work in sequence and so on until all the screws to be tested are tested and stop working.

[0068] In a further preferred embodiment, the positioning detection head 6 is connected to a torque sensor and is externally connected to a corresponding display device, all of which are prior arts and will not be elaborated in this application.

[0069] The industrial camera of the detection unit is in wireless communication with the active positioning unit, and a preset path planning is performed on the adjustment of the working position of the wooden platform by the active positioning unit through the industrial camera. The specific steps are as follows:

[0070] First, place the wooden platform between multiple movable positioning parts, and use an industrial camera to scan and image the overall working size of the wooden platform to confirm it, and divide the wooden platform into regions according to the overall working size of the through holes set in the auxiliary limiting plates;

[0071] Next, let the coordinates of the pixels in any region after segmentation be , , where n is the number of pixels in the area, then the coordinates of the center point of the area The calculation formula is as follows:

[0072] ;

[0073] ;

[0074] Subsequently, the coordinates of the center points of each region are calculated, and a corresponding set D of center point coordinates is generated. , calculate the horizontal distance and vertical distance between two adjacent center point coordinates. The specific formulas are as follows:

[0078] Next, both the horizontal distance and the vertical distance between two adjacent center point coordinates are shortened by half, that is, the shortened horizontal distance is , and the shortened vertical distance is . Starting from the first point of the positions of each center point coordinate in the set D of center point coordinates, calculate the new coordinates of the subsequent points in turn; for the new coordinates of the (i + 1)-th center point are , where:

[0079] ;

[0080] ;

[0081] Where is the new coordinate of the i-th center point;

[0082] Finally, the new coordinates of each calculated center point are output, and a new set of center point coordinates is formed , . The coordinate points in the new set of center point coordinates are connected in series, and a movement adjustment processing path of the corresponding wooden board platform is generated in sequence according to the order of each spatial coordinate point in the new set of center point coordinates .

[0083] Through the above method, torque detection of multiple groups of the same type of screws can be continuously carried out, improving the accuracy of screw torque detection and facilitating the generation and analysis of subsequent data reports. At the same time, if it is necessary to change the type of screws to be detected during the process, the original adjustment path of the wooden board platform will not be interrupted, and there is no need for secondary planning, which is more convenient and efficient.

Various changes in form and detail may be made without departing from the spirit and scope of the present invention as defined by the appended claims.
