Description

Technical Field

[0001] The utility model relates to the field of machinery, in particular to a jig used for spray coating processing. Background Art

[0002] A cosmetic box product has an upper cover and a lower cover. The outer surfaces of the upper cover and the lower cover need to be spray-coated. During the spray-coating process, the upper cover and the lower cover need to be placed on a jig. Due to the difference in the appearance of the upper and lower covers, two different sets of jigs are required. In addition, spraying and coating are performed at two different workstations. Therefore, during production, after the spraying process is completed, the jig needs to be removed from the previous workstation and then installed at the next workstation. The installation and removal process consumes manpower and time. In addition, the upper and lower covers are easily contaminated and scratched during the installation and removal process, which affects the yield rate of the finished product. Utility Model Content

[0003] The purpose of the present utility model is to provide a spray coating jig that can be adjusted from 90 degrees to 180 degrees to solve at least one of the above technical problems.

[0004] The technical problem solved by the present invention can be achieved by adopting the following technical solutions:

[0005] A spray coating fixture capable of being adjusted from 90 degrees to 180 degrees comprises a workbench provided with a support system, the support system comprising a crank, the end surface of one end of the crank being rotatably connected to a rotating rod;

[0006] A handle for pushing the rotation is provided on the rotating rod;

[0007] The rotation angle between the rotating rod and the crank is 90 to 180 degrees;

[0008] The invention also includes a flat plate as a snap plate, wherein the four side edges of the snap plate are set as bevel edges, the bevel edges face the back, and the bevel angles are between 30 and 45 degrees;

[0009] Two cross ribs are provided along the diagonal line on the back of the snap plate;

[0010] A clamping device is provided on the end surface of the distal end of the rotating rod;

[0011] The clamping device includes two cross-elastic grooves;

[0012] The two intersecting grooves of the clamping device are adapted to the two intersecting ribs of the snap plate;

[0013] The rotating rod is clamped and connected to the snap plate through a clamping device;

[0014] The other end of the crank is connected to a side wall facing away from the rotating rod, and the support rod is detachably plugged into the workbench.

[0015] In the above design, the rotating rod can be rotatably connected to the end face of the crank, and a clamping device is provided on the end face of the end of the rotating rod. The clamping mechanism adopts two cross grooves, and the two grooves are respectively interference-connected to the two ribs of the snap plate. The side of the snap plate forms a thin-edge structure through the bevel design. The thin-edge structure makes the four sides of the snap plate elastic, and snap grooves of the same size are provided on one side of the inner surface of the upper cover and the lower cover, and then the snap plate is elastically snapped into the snap grooves of the upper cover and the lower cover, thereby realizing a fixture that meets the installation requirements of the upper cover and the lower cover.

[0016] The rotating track of the rotating rod is perpendicular to the crank, and the rotating rod can be rotated left and right to the work stations on both sides, thereby meeting the requirements of continuous spraying and coating processes in one installation.

[0017] The beneficial effect of this design is that after the workpiece is clamped and installed in the fixture, the workpiece can be positioned at the spraying and coating stations by pushing the handle and rotating the rotating rod, respectively. This allows the two processes to be processed continuously, saving manpower and downtime required during the assembly and disassembly process, thereby improving production efficiency. It also reduces the dirt and scratches that may be caused during the assembly and disassembly process, and improves the spray coating quality of the finished product.

[0018] Furthermore, the snap plate is made of elastic polyurethane or ABS plastic.

[0019] In the above design, polyurethane and ABS plastics have hardness and elasticity, which can meet the requirements of the clip plate for both hardness and elasticity. The beneficial effect is that metal materials are saved and manufacturing costs are reduced.

[0020] Furthermore, the width of the groove is 1 to 3 mm smaller than the width of the rib plate on the flip cover; and the depth of the groove is 2 to 5 mm greater than the height of the rib plate.

[0021] In the above design, the clamping mechanism realizes the clamping function by being clamped on the rib plate of the workpiece through a groove. The width of the groove is smaller than the width of the rib plate on the workpiece. When the groove is clamped on the rib plate, there will be local elastic deformation. The elastic deformation will generate a greater clamping force, clamping the workpiece more firmly on the clamping mechanism.

[0022] The groove depth is greater than the rib plate, allowing the rib plate to be embedded in the groove.

[0023] Furthermore, the crank is rotatably connected to the rotating rod via a T-shaped pin; a tightening device for locking the rotation of the rotating rod is also provided at the connection between the crank and the rotating rod.

[0024] In the above design, the rotatable connection is achieved via a T-pin, which has the advantage of a simple structure and reduced manufacturing costs. A tightening device is also provided to lock the rotation of the rotating rod after it has rotated to a desired angle, preventing the workpiece from rotating during the spray coating process, which could affect the coating effect.

[0025] Furthermore, the rotating rod includes a sleeve with a through hole in the middle of the sleeve, one end of the through hole is fixedly connected to an axle seat component, and the other end of the through hole is detachably connected to a clamping mechanism;

[0026] The shaft seat component includes a shaft seat, a support rod is fixedly connected to the side wall of the shaft seat, and the cross section of the support rod is adapted to the cross section of the through hole;

[0027] The clamping mechanism comprises an elastic columnar body, the cross section of the columnar body is adapted to the cross section of the through hole, and a clamping device is arranged on the end surface of one end of the columnar body facing outwards.

[0028] In the above design, the clamping component is designed as an independent component. The clamping component will wear during use. When the wear is severe, it will lead to the loss of the snap-on effect. The beneficial effect of the above design is that it is replaceable. By restoring the snap-on ability of the jig through replacement, the jig loss cost in the production process can be reduced.

[0029] In a further optimization, the cross section of the through hole is a cross-sectional shape that is larger than a semicircle and smaller than a full circle.

[0030] In the above design, the cross section of the through hole is not a fully circular hole. This design can prevent the clamping component and the shaft seat component sleeved in the through hole from rotating during the spray coating process. Its beneficial effect is that it can improve the quality of the finished product.

[0031] Further optimized, the columnar body of the clamping mechanism is made of polycarbonate plastic.

[0032] In this design, polycarbonate combines high strength and hardness with excellent elasticity. The polycarbonate clamping components utilize their inherent elasticity to enhance the workpiece's grip when gripping the ribs. They also exhibit low expansion and corrosion resistance during spraying and coating processes. This advantageously facilitates clamping and removal, improving installation efficiency.

[0033] In a further optimization, the inner wall of the groove of the clamping device is coated with a rubber layer.

[0034] In the above design, the coated rubber layer can increase the clamping elasticity and clamping friction, which has the beneficial effect of improving the workpiece installation efficiency.

[0035] Further optimization, the side wall of the sleeve is provided with a through threaded hole, and the bolt is screwed onto the clamping component through the threaded hole;

[0036] The clamping part is provided with an arc-shaped groove adapted to the bolt head at a location corresponding to where the bolt is tightened.

[0037] In the above design, the clamping component is fixed in the through hole of the sleeve by means of bolts. The beneficial effect is that the clamping component is fixed by bolts, which has a simple structure and can reduce manufacturing costs.

[0038] Further optimized, the support rod has a head and a root, the root is close to the crank, and the size of the root is larger than the size of the head;

[0039] Circular ribs are arranged on the outer wall of the support rod near the 1 / 3 to 1 / 2 of the root.

[0040] In this design, the head of the support rod is thinner than the base, making it easier to insert into the mounting hole. A circular rib is arranged on the outer wall of the support rod near the base. Its function is to increase the pressure of the support rod on the mounting hole by reducing the contact surface, making the installation more secure.

[0041] The utility model has a rotating rod rotatably connected to the crank end face, and a clamping mechanism is provided at the end of the rotating rod. The clamping mechanism clamps the flip cover. The beneficial effect is that after the flip cover is installed once, both sides of the flip cover can be sprayed or coated separately by rotating the rotating rod, saving manpower and time consumed in the installation and removal process, thereby improving production efficiency. It also reduces dirt and scratches that may be caused to the flip cover during the installation and removal process, and improves the quality of the spraying and coating of the finished product.
