However, it is apparent to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0024] The applicant believes that the loading and unloading operations of the traditional screw torque detection device are not convenient enough and require manual control. At the same time, the adjustment of the wooden platform used in conjunction is also very inconvenient. After the torque detection of a screw is completed, the wooden platform cannot be adjusted in time, resulting in low detection efficiency.

The pushing and limiting assembly includes a movable positioning unit 3 connected to the bearing support unit and having a predetermined working distance between it and the positioning unit; an auxiliary limiting plate 4 connected to the movable positioning unit 3, having a predetermined working size and provided with corresponding alignment through holes. The adjustment and detection assembly 5 includes a supporting positioning unit connected to the base 1, having a predetermined working length and supporting force, which can perform corresponding supporting and bearing operations; and a detection unit slidably connected to the supporting positioning unit, which can perform sliding adjustment operations within a predetermined range. The detection unit is provided with a positioning detection head 6, and the positioning detection head 6 is provided with a positioning groove of a predetermined operation size, and a plurality of special-shaped positioning plates 7 are slidingly provided on the surface of the operation surface; the operation surface of the special-shaped positioning plates 7 is provided with a serrated positioning groove, and there are multiple of them, and the plurality of special-shaped positioning plates 7 are evenly distributed on the operation surface of the positioning detection head 6. A telescopic cross positioning handle 8 is provided in the positioning groove of the positioning detection head 6, so the telescopic cross positioning handle 8 is provided with a corresponding magnetic suction end, and an industrial camera is provided on the operation surface of the positioning detection head 6. In the later operation process, the feeding and receiving processing of the screws can be realized through the feeding and receiving component 2, and the working position of the wooden board platform used in conjunction can be autonomously adjusted through the pushing and limiting component, and the autonomous clamping and detection of the screws to be tested can be realized through the detection unit, as well as the autonomous placement and unloading after the detection is completed.

[0028] In a further preferred embodiment, the working surface of the positioning detection head 6 is provided with three special-shaped positioning plates 7, and the three special-shaped positioning plates 7 are distributed in a triangular array on the working surface of the positioning detection head. In the later operation process, the head position of the screw to be inspected is clamped by multiple special-shaped positioning plates 7. Since the special-shaped positioning plates 7 are provided with serrated positioning grooves, the head of the screw to be inspected can be firmly clamped. The telescopic cross positioning handle 8 is magnetized, and is connected to the positioning detection head 6 through a telescopic rod, and is placed in the positioning groove of the positioning detection head 6. The specific structure of the telescopic cross positioning handle 8 can refer to the blade structure of the plum screwdriver in the prior art, and how to magnetize the telescopic cross positioning handle can refer to the screwdriver processing process in the prior art. The above are all prior art and will not be repeated in this application. In a further preferred embodiment, the telescopic cross-shaped locking handle 8 is threadedly connected to the telescopic rod. In the later operation process, the shape of the blade of the telescopic locking handle can be flexibly adjusted according to actual needs. For example, it can be replaced with a flat head, star shape or hexagonal shape, etc., so as to be suitable for detecting different screws.

[0029] The load-bearing support 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 operating size and supporting force, and can perform corresponding positioning and load-bearing operations; the load-bearing plate 202 is placed on the operating surface of the support frame 201, has a predetermined operating size and load-bearing space, and can perform corresponding load-bearing and position-limiting operations. A support frame with a predetermined load-bearing space is formed by the support frame 201 and the load-bearing plate 202, so as to facilitate the corresponding connection support and load-bearing operations.

[0030] The positioning unit includes two components: a pad 203 and a positioning cylinder 204.

In the later operation process, the multiple positioning cylinders 204 can be driven to move to the corresponding working positions by slidingly adjusting the working positions of the multiple pads 203, thereby realizing the corresponding alternating feeding. In the later operation process, it is only necessary to place the screw to be tested at the limiting through hole of the positioning cylinder 204 and hold the screw to be tested. That is, it is only necessary to ensure that the working size of the head of the screw to be tested is greater than the working size of the limiting through hole set by the positioning cylinder 204. At the same time, the size of the screw handle of the screw to be tested is smaller than the size of the limiting through hole set in the positioning tube 204 , so that the screw to be tested can be supported by the positioning tube 204 .

[0031] The movable positioning unit 3 includes two components: a connecting plate 301 and a positioning part. The connecting plate 301 is placed on the working surface of the load-bearing support unit, has a predetermined working size and load-bearing space, and can perform corresponding load-bearing and connecting positioning operations; the positioning part is placed on the working surface of the connecting plate 301, has a predetermined working size and elasticity, and can perform a predetermined range of telescopic adjustment operations, and there are multiple movable positioning units, which are distributed in an array on the working surface of the connecting plate 301. In a further preferred embodiment, the movable positioning units 3 are four groups, and are arranged symmetrically in pairs, that is, the four groups of movable positioning units are distributed in a rectangular array. In the later operation process, the four movable positioning groups 3 respectively abut against the four sides of the wooden platform, thereby realizing the limit fixation of the wooden platform.

[0032] The positioning part includes three components: a fixed plate 302, a telescopic cylinder 303 and a positioning 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 bearing 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 positioning push plate 304 is connected to the telescopic cylinder 303, has a predetermined working size, and can be adjusted to the corresponding working position following the telescopic adjustment of the telescopic cylinder 303. In the later operation process, the positioning push plate 304 is driven to be adjusted to the corresponding working position by the telescopic adjustment of the telescopic cylinder 303. The multiple telescopic cylinders 303 of the multiple groups of the active positioning units 3 cooperate with each other and perform opposite operations respectively, thereby realizing flexible adjustment of the working direction of the wooden platform to the front, back, left and right, so as to screw the screws to be inspected into the wooden platform, thereby realizing torque detection of the screws to be inspected. In actual operation, the hardness and thickness of the wooden platform can be flexibly adjusted according to actual needs. The role of the wooden platform is to provide a detection platform for the screws to be inspected to be screwed into, so that the corresponding torque data can be collected.

[0033] The auxiliary limiting plate 4 is connected to the connecting plate 301 through a positioning rail 401, and is placed above the working position of the locking part, and a predetermined working space distance is directly reserved with the locking part. There are multiple positioning rails 401, and a predetermined working distance is reserved between the multiple positioning rails 401, and the overall working height of the positioning rails 401 is greater than the overall working height of the locking part. In a further preferred embodiment, the auxiliary limiting plate 4 has a predetermined working thickness, and the overall working size of the alignment through hole provided by the auxiliary limiting plate 4 is adapted to the overall working size of the locking detection head 6, and is greater than the locking detection head. That is, the inner diameter of the alignment through hole provided by the auxiliary limiting plate 4 fits the outer diameter of the locking detection head 6. In the later operation process, the center point position of the locking detection head 6 corresponds to the center positioning of the alignment through hole provided by the auxiliary limiting plate 4, that is, when it is in a coaxial state, the locking detection head 6 can be started to perform the corresponding torque detection operation. During the detection process, the positioning detection head 6 is inserted into the alignment through hole provided in the auxiliary limit plate 4. Since the auxiliary limit plate 4 has a predetermined working thickness, the positioning detection head 6 can be subjected to corresponding auxiliary limiting after the positioning detection head 6 is inserted into the alignment through hole of the auxiliary limit plate 4, so that the positioning detection head 6 can be limited when the screw to be inspected is screwed, thereby avoiding the phenomenon of thread slippage or tilted screwing of the screw to be inspected during the screwing process.

[0034] The support and positioning unit includes four components: a second telescopic cylinder 503, a connection and positioning cover 504, a rotating motor 505, and a connection and rotating wheel 506. The second telescopic cylinder 503 is placed on the working surface of the extension support plate 502, and the cylinder rod passes through the extension support plate 502 and has a predetermined elasticity. The connection 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 be adjusted to the corresponding working position following the telescopic adjustment of the second telescopic cylinder 503. The rotating motor 505 is placed in the hollow chamber of the connection and positioning cover 504, and can provide a predetermined rotation driving force. One end of the connection and rotating wheel 506 is connected to the rotating motor 505 through a transmission track, and can perform corresponding rotation adjustment operations under the drive of the rotating motor 505; the other end is connected to the positioning detection head 6. In a further preferred embodiment, the connecting positioning cover is slidably connected to the supporting positioning column 501. In the later operation process, when the second telescopic cylinder 503 performs the corresponding extension operation, the connecting positioning cover 504 is pushed to perform corresponding sliding adjustment along the working surface of the supporting positioning column 501, thereby driving the rotating motor 505 and the connecting rotating wheel 506 to adjust the corresponding working position.

[0035] In a further preferred embodiment, the engagement and positioning cover 504 is hollow and has an external drive cylinder inside, and the cylinder rod of the external drive cylinder is connected to the engagement rotating wheel 506 through the positioning platform. In the later operation process, the external drive cylinder can be further telescopically adjusted, thereby driving the rotating motor 505 and the engagement rotating wheel 506 to further adjust the operation position.

[0036] Based on the above industrial parts torque detection device, the present invention proposes a detection method for the industrial parts torque detection device, and the specific steps are as follows: First, manually place the screws to be tested on the positioning cylinder 204, and place the wooden platform required for the auxiliary test on the movable positioning unit 3; drive the extended support plate 502 to slide and adjust in the direction close to the positioning cylinder 204, and drive the detection unit as a whole to move and adjust in the direction close to the positioning cylinder 204, and stop the sliding adjustment of the extended support plate 502 when the operating position of the telescopic cross positioning handle 8 provided by the positioning detection head 6 corresponds to the operating position of the center point of the positioning cylinder 204; 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. 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; 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, so that the screw to be tested is screwed into the wooden platform, and the torque of the screw to be tested is tested; Next, the above steps are reversed to place the screws after detection into the positioning tube 204, and then the movable positioning unit 3 is activated to push and adjust the working position of the wooden platform; Finally, repeat the above work in sequence and so on until all the screws to be tested are tested and stop working.

[0037] 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.
