[0021] like Figures 1 to 4 As shown, the present invention provides a pin length measuring device, comprising a base 1, a measuring steel ruler 2, a vertical plate 3, three sets of fixed plates 4, three sets of hydraulic cylinders 5, three sets of arc-shaped clamping plates 6, a moving plate 7, a positioning device, and a moving device. The moving device is installed on the rear side of the top of the base 1, the moving plate 7 is installed on the moving device, the measuring steel ruler 2 is installed on the front end of the moving plate 7, the positioning device is installed on the moving plate 7, the vertical plate 3 is installed on the right side of the top of the base 1, the three sets of fixed plates 4 are equally installed on the left side of the vertical plate 3, the three sets of hydraulic cylinders 5 are respectively installed on the outer ends of the three sets of fixed plates 4, and the output ends of the three sets of hydraulic cylinders 5 respectively pass through the three sets of fixed plates 4 and are connected to the three sets of arc-shaped clamping plates 6.

[0022] Place one end of the pin on the left side of the vertical plate 3, then open the three sets of hydraulic cylinders 5. The three sets of hydraulic cylinders 5 will drive the three sets of arc-shaped clamping plates 6 to move inward to clamp and fix the pin. Then open the moving device, which will drive the moving plate 7 to move forward until it is close to the pin. Then, the positioning device will contact the other end of the pin. At this time, the positioning device is located at the position of the measuring steel ruler 2, which is the length of the pin. By setting up this device, it is easy to measure the length of the pin. The operation is simple and the measurement accuracy is improved.

[0023] As a preferred embodiment of the above, the positioning device includes a first motor 8, a first screw 9, a moving block 10, and a positioning plate 11. The first motor 8 is installed on the left end of the moving plate 7, and the front end of the moving plate 7 is provided with a mounting groove. The first screw 9 is rotatably installed in the mounting groove of the moving plate 7. The output end of the first motor 8 passes through the left end of the moving plate 7 and is connected to the left end of the first screw 9. The moving block 10 slides in the mounting groove of the moving plate 7 and is threadedly connected to the first screw 9. The positioning plate 11 is installed on the front end of the moving block 10 and is located below the measuring steel ruler 2.

[0024] By setting up a first motor 8, a first screw 9, a moving block 10, and a positioning plate 11, the first motor 8 is turned on, which drives the first screw 9 to rotate. The first screw 9 is threadedly connected to the moving block 10, and the moving block 10 drives the positioning plate 11 to move. When the right end of the positioning plate 11 contacts the left end of the pin, the position of the positioning plate 11 and the measuring steel ruler 2 corresponds to the length of the pin, which facilitates precise positioning of the pin and improves its measurement accuracy.

[0025] As a preferred embodiment of the above, the moving device includes a second screw 12, an adjusting block 13, and a second motor 14. The adjusting block 13 is installed at the bottom center of the moving plate 7, and a sliding groove is provided at the rear side of the top center of the base 1.

The adjusting block 13 is threadedly connected to the second screw 12.

[0026] By setting a second screw 12, an adjusting block 13, and a second motor 14, the second motor 14 is turned on, which drives the second screw 12 to rotate. The second screw 12 is threadedly connected to the adjusting block 13, which in turn drives the moving plate 7 to move. This facilitates the adjustment of the position of the moving plate 7, thereby facilitating the disassembly and assembly of the pin and preventing the positioning plate 11 from obstructing the disassembly and assembly of the pin.

[0027] As a preferred embodiment of the above embodiment, a pointer 15 is also included. The pointer 15 is mounted on the top of the positioning plate 11 and corresponds to the position of the measuring steel ruler 2.

[0028] By setting pointer 15, the pin positioning measurement can be made more accurate.

[0029] As a preferred embodiment of the above, it also includes an arc-shaped support plate 16 and a lifting device, wherein the arc-shaped support plate 16 is installed on the front left side of the top of the base 1 via the lifting device;

[0030] By setting up an arc-shaped support plate 16 and a lifting device, the arc-shaped support plate 16 can support a longer pin, thereby ensuring the stability of the pin.

[0031] As a preferred embodiment of the above, the lifting device is configured as an electric push rod 17, which is installed on the top of the base 1 and the arc-shaped support plate 16 is installed on the output end of the electric push rod 17.

[0032] By setting an electric push rod 17, the height of the arc-shaped support plate 16 can be easily adjusted according to the height of the pin.

[0033] As a preferred embodiment of the above embodiment, a contact switch 18 is also included. The contact switch 18 is embedded in the right end of the positioning plate 11 and is electrically connected to the first motor 8.

[0034] By setting a contact switch 18, when the positioning plate 11 contacts the pin, the pin will touch the contact switch 18, and the contact switch 18 will control the first motor 8 to shut down, thus automatically controlling the positioning plate 11.

[0035] As a preferred embodiment of the above, it also includes two sets of guide rods 19 and two sets of guide blocks 20. The left and right sides of the rear side of the top of the base 1 are provided with sliding grooves. The two sets of guide rods 19 are installed in the two sets of sliding grooves of the base 1. The two sets of guide blocks 20 are respectively installed on the left and right sides of the bottom of the movable plate 7. The two sets of guide blocks 20 are slidably connected to the two sets of guide rods 19.

[0036] By setting guide rods 19 and guide blocks 20, when the moving plate 7 moves, the two sets of guide blocks 20 slide on the two sets of guide rods 19, which can improve the stability of the moving plate 7 when it moves.

[0037] This utility model discloses a pin length measuring device. In operation, one end of the pin is first placed on the left end of the vertical plate 3. Then, three sets of hydraulic cylinders 5 are activated, causing three sets of arc-shaped clamping plates 6 to move inward and clamp the pin. Next, the second motor 14 is activated, causing the second screw 12 to rotate. The second screw 12 is threadedly connected to the adjusting block 13, which in turn moves the moving plate 7 closer to the pin. Then, the first motor 8 is activated, causing the first screw 9 to rotate. The first screw 9 is threadedly connected to the moving block 10, which in turn moves the positioning plate 11. When the right end of the positioning plate 11 contacts the left end of the pin, the position corresponding to the measuring steel ruler 2 indicates the length of the pin.

[0038] The pin length measuring device of this utility model has common mechanical installation, connection or setting methods, and can be implemented as long as it can achieve its beneficial effect. The hydraulic cylinder 5, first motor 8, second motor 14, electric push rod 17 and contact switch 18 of the pin length measuring device of this utility model are purchased from the market. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
