[0023] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific circumstances.

[0024] Embodiment 1, as Figure 1 shown, this embodiment discloses a tightening gun and workpiece hole positioning device, including: a tightening gun clamp mounting assembly 1, a workpiece positioning pin assembly 2, and a cylinder-rail-slider linkage device 3;

[0025] As Figure 2 shown, the tightening gun clamp mounting assembly 1 includes a clamp 11, a cylinder body 12, and a cylinder joint 13. The clamp 11 is fixed outside the tightening gun, and the cylinder body 12 is fixed on the side of the clamp 11; the cylinder-rail-slider linkage device 3 includes a rail mounting plate 32 and a rail slider 31. A rail is provided on the rail mounting plate 32, and the rail slider 31 is slidably connected to the rail. The rail slider 31 is fixedly connected to the clamp 11, and the cylinder joint 13 is fixedly connected to the rail mounting plate 32;

[0026] As Figure 3As shown in the figure, the workpiece positioning pin assembly 2 includes a positioning pin 21, a positioning pin fixing block 22, and an adjustment seat 23. The positioning pin 21 is fixedly connected to the positioning pin fixing block 22, the positioning pin fixing block 22 is fixedly connected to the adjustment seat 23, and the adjustment seat 23 is fixedly connected to the slide rail mounting plate 32. When the cylinder body 12 controls the cylinder joint 13 to extend and retract, it simultaneously drives the slide rail mounting plate 32 to extend and retract. At this time, the workpiece positioning pin assembly 2 fixed on the slide rail mounting plate 32 also extends and retracts accordingly. When the positioning pin 21 is inserted into the workpiece positioning hole, the positions of the workpiece positioning hole and the bolt hole at the relative position are also confirmed at this time, and the positioning is completed. Then the tightening gun sleeve descends to start the tightening work.

[0027] As Figure 4 shown in the figure, the cylinder slide rail slider linkage device 3 further includes a limiting member. The relatively adjustable distance between the two limiting members is provided at the upper and lower ends of the slide rail mounting plate 32. The limiting member is an adjusting bolt 22, and threaded holes matching the adjusting bolt are provided at the upper and lower ends of the slide rail mounting plate 32. The tightening gun clamp mounting assembly 1 further includes a limiting plate 15. The limiting plate 15 is fixedly connected to the clamp 11 and is located between the two adjusting bolts 22. When the cylinder body 12 controls the cylinder joint 13 to extend and retract, it simultaneously drives the slide rail mounting plate 32 to extend and retract. At the same time, the adjusting bolt 22 mounted on the slide rail mounting plate 32 and the limiting plate 15 mounted on the clamp 11 interact with each other, thereby achieving a limiting effect.

[0028] A connection port 33 is provided at the bottom of the slide rail mounting plate 32. The cylinder joint 13 is inserted into the connection port from the side to achieve clamping connection. It can fix the slide rail mounting plate 32 and the cylinder joint 13 while also facilitating the disassembly of both aspects, which is convenient for maintenance. This structure can also release the freedom degree of the bending direction of the cylinder rod, enabling the cylinder rod to be free from bending stress and increasing the service life of the cylinder.

[0029] The tightening gun clamp mounting assembly 1 further includes a cylinder mounting seat 14 for mounting the cylinder body 12 and fixing it on the clamp 11.

[0030] Embodiment 2, as Figure 3 shown in the figure, the difference between this embodiment and Embodiment 1 is that an adjustment gasket 24 is provided at the fixing part where the adjustment seat 23 and the slide rail mounting plate 32 are fixedly connected. The number of adjustment gaskets 24 can be adjusted according to the actual hole pitch on site, so that the center of the tightening gun and the center of the workpiece hole can be made to coincide as much as possible, reducing the deviation to meet the use requirements and compensating for the systematic deviation existing in the processing and installation process. Then, the adjustment seat 23, the slide rail mounting plate 32, and the adjustment gasket 24 are connected and fixed by bolts.

[0031] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
