Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic powder spraying, in particular to a spray gun clamp device. Background Art

[0002] In the electrostatic powder spraying process, the spray gun fixture is used to fix the spray gun rod during the electrostatic powder spraying process, and can quickly adjust the fixture height, rod horizontal angle, rod elevation angle, and rod extension length. However, the existing spray gun quick fixture design has several technical problems, which limit its efficiency and accuracy in practical applications, as follows:

[0003] The rotating parts in the prior art are easily worn and have a short service life. Figure 1 In the clamp shown in the figure, the handle bolt 104 is connected to the clamp 103. By tightening the handle bolt 104 and the connecting clamp 103, the gun rod on the part 103 is fixed, and the rotating member 102 is also fixed. The rotating part of the rotating member 102 is a linear protrusion, which increases the friction force and prevents the elevation angle of the gun rod from deflecting. However, the linear protrusion is small and narrow, and is easy to wear. After wear, the friction force on the rotating part is reduced. When the gravity of the gun rod itself is greater than the friction force here, the elevation angle of the gun rod cannot be maintained, which seriously affects the spraying quality. At the same time, when the elevation angle of the gun rod needs to be adjusted, the loosening of the handle bolt 104 will cause the extension length of the gun rod to change, and vice versa, and sometimes the change is very large, which increases the difficulty of adjustment, affects the accuracy of adjustment, and increases the adjustment time.

[0004] Secondly, since the diameters of spray gun barrels produced on the market vary and there is currently no mandatory standard to require the diameter of the spray gun barrel, the existing clamping device needs to be manufactured in corresponding models according to different barrel diameters, which not only has poor versatility but also increases the manufacturing cost of the clamping device.

[0005] Therefore, a novel spray gun fixture device is urgently needed to solve the above-mentioned technical problems. Summary of the invention

[0006] The utility model aims at the shortcomings and deficiencies existing in the prior art and provides a kind of simple and ingenious structural design.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] like Figure 2-Figure 6 As shown, the spray gun clamp device of the utility model includes a base body 4 and a connecting clamp shaft 5, one end of the connecting clamp shaft 5 is a rotating clamping portion 501, and the other end is a gun rod mounting portion 502 matching the gun rod 9 at the rear end of the spray gun 10, and the base body 4 is provided with a transverse clamping hole 401 matching the rotating clamping portion 501, and the rotating clamping portion 501 can be inserted into the clamping hole 401 for relative rotation; the base body 4 located at the front and rear sides of the clamping hole 401 is respectively provided with a support rod mounting portion 402 matching the vertical clamp support rod 8 and a second threaded hole 403 penetrating the clamping hole 401.

[0032] In the above structure, the gun barrel 9 is installed on the gun barrel mounting portion 502, and the gun barrel is driven to rotate by rotating the clamping shaft 5, and the gun barrel 9 can move forward and backward relative to the gun barrel mounting portion 502, so that the extension length of the rear end of the gun barrel and the elevation angle of the gun barrel can be freely adjusted respectively without affecting each other, with high adjustment flexibility, which significantly improves the adjustment efficiency and accuracy of the gun barrel clamp; the structural design is reasonable, which effectively reduces the wear on the rotating part and increases the service life.

[0033] The gun barrel mounting hole 503 is a gourd-shaped structure formed by the intersection of two circular holes of different diameters. A first handle bolt 1 matching the gun barrel 9 is installed in the first threaded hole 504. When the gun barrel 9 is adjusted to a suitable length, the bottom of the screw rod can abut against the outer wall of the gun barrel 9 by tightening the first handle bolt 1, and the gun barrel 9 is firmly fixed inside the gun barrel mounting hole, so that the length of the gun barrel 9 can be independently adjusted. In addition, of the two circular holes in the gourd-shaped structure, the diameter of the circular hole close to the clamping hole 401 is 32 mm, and the diameter of the outer circular hole is 38 mm. In the above structure, the gun barrel mounting hole of the gun barrel mounting part connected to the clamping shaft is set into a gourd-shaped structure, so that the same clamp can clamp the gun barrel 9 of any diameter between 32 and 38 mm, which enhances the versatility of the clamp and reduces the cost of production and use of the spray gun clamp; the overall use adjustment operation process saves time and effort, and significantly improves work efficiency and product quality.

[0034] The outer end of the rotating clamping part 501 is detachably mounted on the base body 4 by means of a screw 7 and a gasket 6; the diameter of the gasket 6 is larger than the diameter of the clamping hole 401. A gasket mounting groove matching the gasket 6 is also provided on the side wall of the base body 4, and the screw rod of the screw 7 passes through the gasket 6 and is detachably mounted on the rotating clamping part 501. In the above structure, the combination of the screw 7 and the gasket 6 ensures the stability of the rotating clamping part 501 and the base body 4 in the final use of the structure, and the smoothness of the rotation adjustment of the rotating clamping part 501, thereby improving the flexibility and accuracy of the adjustment of the entire spray gun fixture.

[0035] The second handle bolt 2 is connected to the second threaded hole 403 of the holder body 4. An annular groove 505 is axially arranged at a position corresponding to the second threaded hole 403 on the rotating clamping portion 501. The width of the annular groove 505 is greater than or equal to the width of the second threaded hole 403, so that the bottom of the second handle bolt 2 can be inserted into the annular groove 505 for clamping, further increasing the stability of the connection between the holder body 4 and the rotating clamping portion 501, and preventing relative sliding during use, which affects the use of the spray gun 10. In this structure, when the gun rod 9 is rotated to a suitable angle by rotating the rotating clamping portion 501, the bottom of the screw rod is abutted against the inner position of the annular groove by rotating the second handle bolt 2, thereby realizing the locking of the rotating clamping portion 501, ensuring that the gun rod 9 can be stably maintained at the desired angle, avoiding the spraying quality of the spray gun 10 affected by the angle change during operation, and realizing the independent adjustment of the elevation angle of the gun rod 9.

[0036] The support rod mounting portion 402 is a vertical mounting groove that matches the clamp support rod 8, and the clamp support rod 8 can be inserted into the vertical mounting groove; the side of the vertical mounting groove away from the gun barrel mounting portion 502 and the clamp body 4 are chamfered inclined surface structures, and the chamfered inclined surface is horizontally penetrated with a third threaded through hole 404 connected to the vertical mounting groove, and the third threaded through hole 404 is connected to the third handle bolt 3. In this structure, the clamp support rod is fixed to the inside of the vertical mounting groove by the third handle bolt 3. Through the locking function of the third handle bolt 3, it can be ensured that the clamp support rod will not loosen or fall off after being fixed, thereby ensuring reliability during use.

[0037] The usage process is as follows:

[0038] First, adjust the adjustment handle of the third handle bolt 3, and install the clamp support rod inside the vertical installation groove of the card seat body 4 by rotating the adjustment handle of the third handle bolt 3. Pass the rear end of the gun rod 9 through the gun rod installation hole 503 of the gun rod installation part 502. Due to the gourd-shaped structure of the gun rod installation hole 503, the gun rod 9 can be adjusted at will within the minimum and maximum widths of the gourd-shaped structure. During use, the minimum width of the gourd-shaped structure is 32mm, and the maximum width of the gourd-shaped structure is 38mm, which can meet the use of gun rods 9 of any size of 32 to 38mm in actual use. The use range is wide and meets the use requirements of gun rods 9 of various sizes. After adjusting the length of the rear end of the gun rod 9 to make the spray gun 10 reach the required position length, adjust the adjustment handle of the first handle bolt 1, and rotate the adjustment handle of the first handle bolt 1 to make the end of its screw abut against the side wall of the gun rod 9 in the gun rod installation hole 503, thereby fixing the gun rod 9 in the gun rod installation hole 503.

[0039] Secondly, the rotating clamping portion 501 of the connecting clamping shaft 5 is rotated. Since the connecting clamping shaft 5 is rotatably installed in the clamping hole 401 of the clamping seat body 4, the gun rod 9 can be adjusted to rotate freely to a desired angle in the vertical plane.

[0040] When the gun barrel 9 rotates to a suitable angle along with the rotating clamping portion 501, the adjusting handle of the second handle bolt 2 is adjusted. By rotating the adjusting handle of the second handle bolt 2, the end of the screw rod abuts against the inside of the annular groove on the rotating clamping portion 501 in the clamping hole 401, thereby limiting and fixing the locking rotating clamping portion 501 in the clamping hole 401 of the clamping seat body 4, further ensuring that the gun barrel 9 can be stably maintained at the desired angle.

[0041] Finally, the screw assembly at the end of the rotating clamping part 501 is locked and fixed, that is, the length and angle of the gun barrel 9 of the spray gun 10 are adjusted and installed, and then the spray gun 10 is used for spraying. During the spraying process, if the length or angle of the gun barrel 9 needs to be adjusted again, it is only necessary to repeatedly adjust the tightness and fixation of the first handle bolt 1, the second handle bolt 2 and the third handle bolt 3 to complete the operation.

[0042] In summary, the spray gun clamp device of the utility model realizes completely independent adjustment of the extension length and elevation angle of the rear end of the gun barrel 9 by improving the connecting shaft structure and the gun barrel mounting hole design. Each position does not affect each other, and the adjustment is simple and fast. Each position can be completed within 2-5 seconds, which significantly improves the work efficiency of gun barrel adjustment and the accuracy of adjustment. At the same time, it increases the service life and versatility of the clamp, simplifies the operation process and improves product quality, effectively reduces the friction between rotating parts, and the actual adjustment life can be greater than 2000 times.
