[0028] The clamping assembly 2 includes an upper cover 3 and a lower cover 4. The upper cover 3 is above the lower cover 4. The decorative piece 9 is placed on the upper cover 3. The upper cover 3 includes a first support plate. The first support plate has a recessed first placement groove 301 for matching the shape of the decorative piece 9. Two first positioning pins 302 protrude upwards inside the first placement groove 301. The top surfaces of the two sets of first positioning pins 302 are higher than the top surface of the first support plate. A second positioning pin 303 is provided below the first support plate and is coaxially arranged with the first positioning pins 302. The first positioning pin 302 has two through-holes running through it. The first through hole 302-1 at the end, the second positioning pin 303 is provided with a second through hole 303-1 that passes through its upper and lower ends, the first through hole 302-1 and the second through hole 303-1 are connected, the locking rod 7 passes through the first through hole 302-1 and the second through hole 303-1; the lower cover 4 includes a second support plate, the second support plate is provided with a recessed second storage groove 401 for matching the shape of the decorative part 9, the second support plate is provided with a mounting hole 402 that passes through the upper and lower ends of the second support plate, and the second positioning pin 303 is inserted into the mounting hole 402.

[0029] The outer diameter of the first positioning pin 302 is smaller than the outer diameter of the second positioning pin 303, and the inner diameter of the first through hole 302-1 is smaller than the inner diameter of the second through hole 303-1. The first positioning pin 302 is inserted into the second through hole 303-1 of the other upper cover 3, and the second positioning pin 303 is inserted into the mounting hole 402, thereby stacking and inserting multiple sets of clamping components 2.

[0030] The first support plate has a first inclined surface 304 on its outer periphery facing the second support plate, and the second support plate has a second inclined surface 403 on its outer periphery facing the first support plate. The first inclined surface 304 and the second inclined surface 403 contact to form a V-shaped notch 5. The V-shaped notch 5 structure facilitates the separate removal and installation of the upper cover 3 and the lower cover 4.

[0031] The base plate 1 includes a third support plate. A recessed third storage groove 101 is provided above the third support plate for matching the shape of the decorative part 9. A third positioning pin 102 is provided above the third storage groove 101 and is inserted into the second through hole 303-1 in the clamping assembly 2 of the upper layer. A fourth positioning pin 103 is provided below the third support plate and is coaxially arranged with the third positioning pin 102. The third positioning pin is provided with a third through hole 102-1 that passes through its upper and lower ends. The fourth positioning pin 103 is provided with a fourth through hole 103-1 that passes through its upper and lower ends. The third through hole 102-1 and the fourth through hole 103-1 are connected. The bottom of the locking rod 7 passes through the fourth through hole 103-1 and locks with it.

[0032] The pressure cap 6 includes a fourth support plate. The top of the fourth support plate has two upward-protruding fifth positioning pins 601, corresponding to the first positioning pin 302 on the clamping assembly 2. Below the fourth support plate is a sixth positioning pin 602, coaxially arranged with the fifth positioning pins 601. The fifth positioning pin has a fifth through hole 601-1 penetrating its upper and lower ends, and the sixth positioning pin 602 has a sixth through hole 602-1 penetrating its upper and lower ends. The fifth through hole 601-1 and the sixth through hole 602-1 are... The fifth positioning pin 601 has a first baffle 603 protruding upward at its top. Two sets of the first baffle 603 are symmetrically arranged along the axis of the fifth positioning pin 601. Two sets of second baffles 104 protrude axially from the fourth through hole 103-1, symmetrically arranged along their axis. The locking rod 7 includes a connecting rod 701, a locking plate 702, and a limiting block 703. The locking plate 702 is above the connecting rod 701, and the limiting block 703 is below the connecting rod 701. Below, the limiting block 703 has a U-shaped structure. The connecting rod 701 is inserted into the opening of the limiting block 703. The length of the locking plate 702 is greater than the outer diameter of the fifth positioning pin 601. The locking plate 702 is above the fifth positioning pin 601, keeping the locking plate 702 at the top of the fifth positioning pin 601. The locking plate 702 is designed to facilitate the operator to hold it and rotate the connecting rod 701. The limiting block 703 is inside the fourth through hole 103-1. The distance between the two sets of second baffles 104 is greater than that of the limiting block. The width of 703 is such that the limiting block 703 passes through the two sets of second baffles 104 until it reaches the bottom of the two sets of second baffles 104. The distance between the two sets of second baffles 104 is less than the length of the limiting block 703. That is, when the limiting block 703 rotates, the top surface of the limiting block 703 abuts against the bottom of the second baffle 104. Since there is a locking plate 702 above the connecting rod 701 abutting against the fifth positioning pin 601, that is, after the locking rod 7 is tightened, the pressure cover 6, the clamping assembly 2 and the base plate 1 can be limited and locked.

[0033] Please see Figure 14During installation, the base plate 1 is equivalent to the top cover 3. The decorative part 9 to be sprayed is placed on the base plate 1, and then the lower cover 4 on the clamping assembly 2 is placed on the decorative part 9. The lower cover 4 is placed inside the decorative part 9, keeping the outer ring of the decorative part 9 to be sprayed outside the clamping assembly 2. After the lower cover 4 is in place, the top cover 3 is inserted. The second positioning pin 303 of the top cover 3 passes through the mounting hole 402 of the lower cover 4 and is inserted into the third positioning pin 102 on the base plate 1. The third positioning pin 102 is inserted into the second through hole 303-1, that is, the decorative part 9 is pressed between the base plate 1 and the lower cover 4; then the next group is assembled. To install, place the decorative part 9 to be painted on the upper cover 3, then place the lower cover 4 inside the decorative part 9, and then press another set of upper covers 3 under the lower cover 4. Stack and press in this way until the pressure cover 6 is pressed onto the top decorative part 9. The first positioning pin of the top upper cover 3 is inserted into the sixth through hole 602-1 of the pressure cover 6. The locking rod 7 passes through the fifth positioning pin 601 to the fourth pin of the base plate 1. By rotating the locking plate 702, the limiting block 703 at the bottom of the connecting rod 701 is rotated in a certain direction, and the top of the limiting block 703 is pressed against the bottom of the second baffle 104, thus completing the installation of the decorative part 9 on the fixture.

[0034] Compared with the prior art, the camera decorative part spraying positioning fixture of this application adopts a three-dimensional stacking installation mode, which is simple and quick to install. During the processing, the fixture of this application can be directly rotated for processing, so that the spraying of the decorative part is more uniform. The entire fixture occupies a small area and can spray multiple decorative parts at the same time, effectively improving its processing efficiency and quality.
