[0002] Hexagonal flange screws are fasteners composed of a hexagonal head, a flange, and a screw. They are tools that use the physical and mathematical principles of the circular rotation of the inclined surface of an object and the friction force to gradually fasten objects and mechanical parts. Hexagonal flange screws are widely used in important industries such as ports, electric power, steel, shipbuilding, petrochemicals, mining, railways, construction, metallurgy and chemical industry, automobile manufacturing, plastic machinery, industrial control, highways, large-scale transportation, pipeline auxiliary installation, slope tunnels, shaft management and protection, maritime rescue, marine engineering, airport construction, bridges, aviation, aerospace, stadiums, and other important industries as well as mechanical equipment of infrastructure projects.

[0003] In the machinery industry, the head height of hexagonal flange screws directly affects the assembly of the product. In traditional processing, comparative measurements such as calipers are often used to determine whether they are qualified. During the measurement process, the worker needs to hold the screw in one hand and the measuring equipment in the other hand, which causes inconvenience to the measurement personnel. Based on this, we propose a hexagonal flange wood screw head height measurement device. Utility Model Content

[0005] The utility model provides a device for measuring the head height of hexagonal flange wood screws, which adopts the following technical solutions:

[0006] A device for measuring the head height of a hexagonal flange wood screw comprises a base plate, a trough body is installed at the right end of the top of the base plate, positioning components are provided on both sides of the trough body, a screw body is placed between two groups of positioning components, a vertical plate is installed at the left end of the top of the base plate, a lifting component is provided on the right side of the vertical plate, a mounting plate is installed on the right side of the lifting component, a second electric push rod is installed at the end of the mounting plate facing away from the lifting component, a movable plate is installed at the output end of the second electric push rod, and a measuring component is provided on the side of the movable plate close to the screw body.

[0007] By adopting the above technical solution, the lower end of the screw body is placed inside the groove body, the screw body is positioned by the positioning assembly, and the height of the mounting plate is adjusted by the lifting assembly. The mounting plate adjusts the height of the measuring assembly through the second electric push rod and the movable plate. When the measuring assembly is adjusted to a suitable height, the second electric push rod is controlled to extend, and the extension of the second electric push rod drives the measuring assembly to move toward the direction of the screw body, thereby being able to measure the height of the screw body head.

[0008] Optionally, the positioning assembly includes two groups of first electric push rods, which are respectively installed on both sides of the trough body, and the output ends of the two groups of first electric push rods are installed with positioning plates, which are both located inside the trough body, and the two groups of positioning plates are connected to a plurality of protruding teeth on one side close to the center of the trough body.

[0009] By adopting the above technical solution, when the screw body needs to be positioned, the first electric push rod is controlled to extend, and the extension of the first electric push rod drives the positioning plate to move toward the direction of the screw body until the two sets of positioning plates clamp and fix the screw body. At the same time, the friction between the positioning plate and the screw body is increased by the setting of the convex teeth, thereby making the screw body clamped more firmly.

[0010] Optionally, pulleys are installed at the bottom of the two groups of positioning plates, and slide rails are provided at both ends of the bottom wall of the trough body, and the slide rails are rollingly connected to the pulleys.

[0011] By adopting the above technical solution, when the positioning plate moves, it can drive the pulley to roll inside the slide rail, so that the positioning plate moves more smoothly and avoids jamming as much as possible.

[0012] Optionally, the lifting assembly includes a connecting plate, which is installed at the top of the right side of the vertical plate, and a one-way screw is connected between the bottom of the connecting plate and the top of the base plate through a bearing.

[0013] By adopting the above technical solution, the servo motor drives the one-way screw to rotate when it starts. Under the sliding cooperation of the slide groove and the slider, the one-way screw rotates to drive the first nut to move up and down. The movement of the first nut drives the mounting plate to move up and down, thereby being able to adjust the height of the mounting plate.

[0015] By adopting the above technical solution, when the movable plate moves, it can drive the guide rod to slide in the guide hole, thereby supporting the movable plate, making the movable plate more stable during the movement.

[0016] Optionally, the measuring assembly includes two groups of support plates, the two groups of support plates are respectively installed at the top and bottom of the right side of the movable plate, the two groups of support plates are connected with a bidirectional screw rod through a bearing, the top of the upper support plate is installed with a forward and reverse motor for driving the bidirectional screw rod to rotate, both ends of the outer wall of the bidirectional screw rod are screwed with a second nut, the right ends of the two groups of second nuts are connected to the measuring plate, the left ends of the two groups of second nuts are connected to the sliding sleeve, the two groups of support plates are installed with a sliding rod at one end close to the bidirectional screw rod, the two groups of sliding sleeves are both sleeved on the outside of the sliding rod, the ends of the two groups of sliding sleeves facing away from the second nut are connected to a pointer, and a scale is installed on the side of the movable plate close to the sliding rod.

[0017] By adopting the above technical solution, when the forward and reverse motors are started, the bidirectional screw rods are driven to rotate, and the rotation of the bidirectional screw rods drives the two sets of second nuts to move and approach each other. When the second nuts move, the sliding sleeves are driven to move along the sliding rods, thereby limiting the second nuts. When the sliding sleeves move, the pointers are driven to slide along the scale. When the second nuts move, the measuring plates are also driven to move, and the height of the screw body head can be measured by the two sets of measuring plates.

[0018] Optionally, the center line of the pointer and a side of the measuring plate close to the center of the bidirectional screw are on the same horizontal plane.

[0019] By adopting the above technical solution, the distance between the two groups of pointers is read through the scale on the ruler, and the height of the screw body head can be measured.

[0035] Working principle: When in use, the staff inserts the bottom of the screw body 7 into the interior of the slot 5, and then controls the first electric push rod 605 to extend. The extension of the first electric push rod 605 drives the positioning plate 604 to move toward the direction of the screw body 7 until the two sets of positioning plates 604 clamp and fix the screw body 7. At this time, the convex teeth 603 are in direct contact with the screw body 7, which increases the friction between the positioning plate 604 and the screw body 7, making the screw body 7 clamped more firmly.

[0036] Next, the staff starts the servo motor 101. When the servo motor 101 is working, it drives the one-way screw 103 to rotate. Under the sliding cooperation of the slide groove 104 and the slider 106, the one-way screw 103 rotates to drive the first nut 105 to move downward. The downward movement of the first nut 105 drives the mounting plate 10 to move downward, and then the measuring component 11 can be driven downward through the guide component 9 and the movable plate 4 until the head of the screw body 7 is located between the two sets of measuring plates 1109.

[0037] At this time, the second electric push rod 8 is controlled to extend, and the second electric push rod 8 extends to drive the movable plate 4 to move to the right, and at the same time, the forward and reverse motor 1105 is started. When the forward and reverse motor 1105 is working, it drives the bidirectional screw rod 1107 to rotate. Under the sliding cooperation of the slide rod 1103 and the sleeve 1104, the bidirectional screw rod 1107 rotates to drive the two groups of second screw nuts 1108 to move and approach each other. The movement of the two groups of second screw nuts 1108 drives the measuring plate 1109 to move and approach each other until the two groups of measuring plates 1109 are fitly connected with the head of the screw body 7. While moving, the sleeve 1104 can drive the pointer 1102 to move along the scale 1101, so that the height of the head of the screw body 7 can be measured by reading the scale on the scale 1101.

[0038] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
