[0039] Example 1

[0040] like Figures 1-4 As shown, this embodiment provides a spraying fixture, including a support rod and a hook 14. The support rod is provided with a sliding groove 121 and a positioning groove 122. The positioning groove 122 is distributed at intervals along the extension direction of the sliding groove 121. The hook 14 is slidably disposed in the sliding groove 121, and when the hook 14 slides to the position of the positioning groove 122, the position of the hook 14 is fixed.

[0041] When the size or model of the workpiece changes, or when the position of the workpiece needs to be changed, the hook 14 can slide along the slide groove 121 to move the hook 14 to a set position. A positioning groove 122 is provided at the set position to fix the position of the hook 14, ensuring that the position of the hook 14 is fixed when the workpiece is suspended, and avoiding the workpiece from shifting position and affecting the spraying effect. This application only requires a small number of hooks 14 to achieve the adaptation and suspension of different workpieces. There are no extra hooks 14 that interfere with the workpiece. Without affecting the applicability of the hanger, it can also improve the stability of the workpiece suspension.

[0042] The hook 14 in the application is used to insert into the positioning hole of the workpiece to fix the workpiece, and carry the workpiece to be fixed in the support rod. The workpiece in the application refers to a sheet metal part, the thickness of the sheet metal part is relatively thin, and the edge position of the sheet metal part is provided with a positioning hole, the inner diameter of the positioning hole is slightly larger than the outer diameter of the hook 14, and the hook 14 can pass through the positioning hole to hang the sheet metal part. The sheet metal part can be sprayed on one side or two sides in the spraying process, and it is necessary to ensure the stability of the sheet metal part during spraying, so as to form uniform spraying.

[0044] The sliding groove 121 in the application can be a track extending along the horizontal direction or the vertical direction, which is used to adjust the position of the hook 14 in the support rod, that is, to adjust the suspension position of the workpiece. When the sliding groove 121 is a track extending horizontally, the hooks 14 symmetrically arranged on the left and right sides in the sliding groove 121 can be used to suspend both ends of the workpiece. When the size of the workpiece becomes larger, that is, the gap between the two positioning holes in the workpiece becomes larger, the gap between the two hooks 14 needs to be correspondingly adjusted to become larger. When the size of the workpiece becomes smaller, that is, the gap between the two positioning holes in the workpiece becomes smaller, the gap between the two hooks 14 needs to be correspondingly adjusted to become smaller.

[0045] For the sliding groove 121 extending horizontally, hooks 14 are usually arranged on the left and right sides thereof, which are used to suspend the same workpiece or two workpieces, so as to ensure that the center of gravity of the support rod is in the middle, and the stability of the whole hanger is improved.

[0046] For the sliding groove 121 extending vertically, a plurality of hooks 14 can be arranged in the sliding groove 121, and for workpieces with different heights, the height of the hook 14 can be adjusted to adjust the suspension position of the adjacent workpiece.

[0047] The positioning groove 122 in the application is arranged at the position where the hook 14 needs to be fixed in the sliding groove 121. When the hook 14 slides along the sliding groove 121, the hook 14 can be lifted up, so that the end of the hook 14 slides along the sliding groove 121. When the hook 14 slides to the position of the corresponding positioning groove 122, the hook 14 can be pressed down, so that the hook 14 is embedded in the inside of the positioning groove 122. At this time, the hook 14 is limited by the positioning groove 122 and cannot move in position.

[0048] On the basis of the positioning groove 122, the hook 14 and the sliding groove 121 can also be locked by means such as locking screws to avoid the position of the hook 14 moving during the suspension of the workpiece. Specifically, the locking screw can be arranged at the side of the positioning groove 122 to lock the hook 14 inside the positioning groove 122.

[0073] In actual operation, the two upper horizontal rods 12 are used for suspending the chassis assembly, and each horizontal rod 12 suspends one chassis assembly at each end, and each chassis assembly only needs to be suspended in one hook 14. At this time, the two hooks 14 in the same horizontal rod 12 can be slid to the symmetrical group with a distance of 168 cm, so as to ensure that the distance between the two chassis assemblies is far enough and the center of gravity falls at the position of the vertical rod 11, thereby realizing the balance of the two sides of the hanger.

[0074] The lower horizontal rod 12 is used for suspending the rear side plate, and the lowermost horizontal rod 12 simultaneously suspends four rear side plates, i.e. two rear side plates are suspended on each side with the vertical rod 11 as the center, the four rear side plates are suspended in the symmetrical groups with a distance of 112 cm and 224 cm respectively, so as to ensure that the distance between the adjacent rear side plates is far enough and the center of gravity falls at the position of the vertical rod 11, thereby realizing the balance of the two sides of the hanger.

[0075] ​The hook 14 in the embodiment includes a connecting piece 141 and a hanging piece 142. One end of the connecting piece 141 is slidingly located in the sliding groove 121, and the other end of the connecting piece 141 is fixedly connected with the hanging piece 142. The hanging piece 142 is an arc-shaped structure, and the arc-shaped structure includes a corner. The connecting piece 141 of the hook 14 is a spherical structure matched with the inner diameter of the sliding groove 121, and is embedded in the sliding groove 121. The hanging piece 142 of the hook 14 can be embedded in the positioning groove 122. When the hook 14 needs to be slid, the hanging piece 142 needs to be pulled out of the positioning groove 122, at which time the hook 14 can be slid. When the hook 14 is slid to a preset position of the positioning groove 122, the hanging piece 142 is embedded in the positioning groove 122, so that the position of the hook 14 in the sliding groove 121 is fixed.

[0076] On the basis of the positioning groove 122, the hook 14 and the sliding groove 121 can also be locked by means of a locking screw or the like to avoid position movement of the hook 14 during suspension of the workpiece. Specifically, the locking screw can be arranged at a side position of the positioning groove 122 to lock the hook 14 in the positioning groove 122.

[0077] The outer diameter of the hook 14 in the application is matched with the inner diameter of the positioning hole in the workpiece. When the workpiece is suspended, the hook 14 only needs to be inserted into the corresponding positioning hole. The application defines the first end of the circular truncated cone connecting part 143 as the side of the circular truncated cone connecting part 143 away from the supporting rod, and defines the second end of the circular truncated cone connecting part 143 as the side of the circular truncated cone connecting part 143 close to the supporting rod. The outer diameter of the second end of the circular truncated cone connecting part 143 is equal to the outer diameter of the hook 14, and the outer diameter of the first end of the circular truncated cone connecting part 143 is smaller than the outer diameter of the hook 14. In this way, the circular truncated cone connecting part 143 can guide the positioning hole to be quickly and conveniently inserted into the hook 14 and stably suspended at the corner position of the hook 14.

[0078] By adjusting the position change of the connector 15, the position adjustment of the different interval horizontal rods 12 can be realized. Specifically, a plurality of horizontal rods 12 are arranged in the same vertical rod 11 in the application, for realizing suspension of the workpiece on different layers. When the height of the workpiece changes, the distance between the horizontal rods 12 can be adjusted by adjusting the connector 15, so that the hanger can adapt to suspension of workpieces of different heights.

[0079] The adjusting connector 15 includes a first connecting part 151 and a second connecting part 153 fixedly connected, the first connecting part 151 is a ring structure with an opening, such as Figure 6As shown, the inner diameter of the annular structure is 7 cm, the outer diameter is 10 cm, and the span of the opening is 5 cm. The first connecting hole 152 is arranged on both sides of the opening of the first connecting part 151, the inner diameter of the first connecting part 151 is matched with the outer diameter of the vertical rod 11, and the first connecting part 151 is used for detachable connection with the vertical rod 11. As shown in Figure 6 As shown, the second connecting part 153 is a linear structure, the length of the second connecting part 153 is 50 cm, and the second connecting hole 154 is arranged at both ends of the second connecting part 153, and the inner diameter of the second connecting hole 154 is 5 cm. The second connecting part 153 is used for detachable connection with the horizontal rod 12.

[0080] In the present application, the first connecting part 151 is used for detachable connection with the vertical rod 11, and specifically can be provided as an annular structure with an opening, and the inner diameter of the annular structure is matched with the outer diameter of the vertical rod 11. By opening the opening, the inner diameter of the annular structure can be expanded, so that the first connecting part 151 is nested on the outside of the vertical rod 11. After the first connecting part 151 is nested on the outside of the vertical rod 11, the first connecting hole 152 on both sides of the opening is locked by a locking screw, so that the inner diameter of the annular structure is reduced, and the fixed connection between the vertical rod 11 and the first connecting part 151 is realized. The second connecting part 153 in the present application is a linear structure, that is, parallel to the horizontal rod 12. The second connecting hole 154 is arranged at both ends of the second connecting part 153. The third connecting hole matched with the first connecting hole 152 is arranged in the horizontal rod 12. The first connecting hole 152 and the third connecting hole are locked by a locking screw to realize the fixation between the adjusting connector 15 and the horizontal rod 12. Since the first connecting part 151 is nested on the outside of the vertical rod 11, when the first connecting part 151 and the vertical rod 11 are not locked, the position of the first connecting part 151 in the vertical rod 11 can be adjusted.

[0081] The shape of the hanger in the present application is adapted to the shape of the product. According to the shape of the product, the upper horizontal rod 12 is designed as two-point and two-side slidable hooks 14, and the lower side is designed as four-point uniform slidable hooks 14, so that the product is stably hung, the product stability is ensured when the line runs, and the product loss problem caused by dropping is reduced.

[0082] In order to ensure product quality and process requirements, according to quality control and process operation requirements, the chassis assembly and the rear side plate are double-sided sprayed. In order to solve the structure problem of product contact points, the previous hanging needle is replaced by a replaceable and slidable hook 14, the product powder spraying area is increased, and the spraying defect caused by static shielding is reduced.

[0083] The present application can satisfy the mixed hanging production and use of the chassis assembly and the rear side plate, ensure the rapid and accurate hanging positioning and unloading of the product, reduce the operation time, and speed up the production process.

[0084] The embodiment adjusts the hanging distance between products according to the operation structure of the spraying line and the layout of the spray gun, reasonably arranges the mixed hanging position of 4+4 products, reduces the distance between hanging points, makes the products evenly distributed, maximizes the reduction of powder settlement loss, and improves the powder utilization rate.
