Description

Technical Field

[0001] The invention relates to the technical field of grinding equipment, and in particular to a processing equipment for surface spraying. Background Art

[0002] Spraying is a coating method that uses a spray gun or a disc atomizer with the help of pressure or centrifugal force to disperse into uniform and fine droplets, and then apply them to the surface of the coated object. Before spraying the workpiece, the surface of the workpiece needs to be polished. Polishing can not only increase the flatness, roughness and smoothness of the workpiece surface, reduce surface defects, but also remove the oxide layer, rust and other impurities on the surface of the workpiece, thereby improving the adhesion and flatness of the spray coating, making the coating smoother and brighter, and at the same time making the workpiece after spraying have a better appearance.

[0021] like Figure 1-Figure 7 A processing equipment for surface spraying shown in the figure comprises a grinding table 1, and a grinding mechanism 2 arranged on the grinding table 1, a conveying mechanism 3 for conveying workpieces is arranged on the grinding table 1, it should be noted here that the grinding mechanism 2 and the conveying mechanism 3 are both mature technologies in the prior art, and no more description is given here, and the conveying mechanism 3 conveys the workpiece in an intermittent conveying manner, a fixed box 5 is fixedly connected to the top of the grinding table 1 through a plurality of supporting legs 4, a material unloading frame 6 is arranged on the front side of the grinding table 1 and at a position corresponding to the fixed box 5, a bottom plate 7 is slidably connected to the inner side of the material unloading frame 6, a material frame 8 for placing workpieces is arranged on the bottom plate 7, and a material unloading mechanism for pushing the workpiece from the conveying mechanism 3 to the material frame 8 is arranged in the fixed box 5; The unloading mechanism includes an unloading motor 9, a reciprocating screw 10 is rotatably connected to the inner side of the fixed box 5, a sliding block 11 is threadedly connected to the outer wall of the reciprocating screw 10, a sliding groove 12 is provided at the bottom of the fixed box 5, a hinge seat 13 is fixedly connected to the bottom of the sliding block 11 and located at the sliding groove 12, a push plate 14 is hingedly connected to the inner side of the hinge seat 13, a top plate 15 is fixedly connected to the side wall of the push plate 14, and a limit plate 16 abutting against the top plate 15 is fixedly connected to the bottom end of the side wall of the sliding block 11, the unloading motor 9 is fixedly connected to the side wall of the fixed box 5, and the output end of the unloading motor 9 passes through the inner side of the fixed box 5 and is fixedly connected to the side wall of the reciprocating screw 10; A recessed groove 17 is provided at the top of the top plate 15, and a pair of upper springs 18 are fixedly connected between the groove 17 and the bottom of the limit plate 16. The upper springs 18 are provided to facilitate pulling the top plate 15 to quickly reset. A positioning plate 19 is fixedly connected to the top of the grinding table 1 and is located next to the conveying mechanism 3 and away from the side of the blanking frame 6. The positioning plate 19 can limit the sliding position of the workpiece backward. The positioning plate 19 is arranged below the fixed box 5. A notch 20 is provided at the top of the positioning plate 19 and at a position corresponding to the push plate 14. The notch 20 prevents the push plate 14 from moving to the side of the workpiece; When pre-treating the workpiece before spraying, the workpiece is first placed on the conveyor belt on the conveying mechanism 3 in sequence, and the push block on the conveyor belt drives the workpiece to intermittently pass through the grinding mechanism 2 for grinding treatment. After the grinding is completed, the workpiece is intermittently transported to the bottom of the fixed box 5 through the conveying mechanism 3, and the unloading motor 9 can be controlled to start and drive the reciprocating screw 10 to rotate, thereby driving the threaded sliding block 11 to move, and entering to drive the push plate 14 to pass through the notch 20 to push the workpiece on the conveyor belt to move, thereby pushing the workpiece into the material frame 8; Then the sliding block 11 moves to the end of the reciprocating screw rod 10, thereby driving the sliding block 11 to slide back. At this time, the workpiece on the conveyor belt is pushed to the bottom of the fixed box 5 again, and then the reset push plate 14 will be hindered by the workpiece, causing the push plate 14 to flip around the hinge until the push plate 14 flips to the upper surface of the workpiece, and at the same time, it will pull the top plate 15 to rotate and stretch the upper spring 18. Then, when the push plate 14 passes through the notch 20, the push plate 14 loses the extrusion of the workpiece, and then the elastic force of the upper spring 18 pulls the top plate 15 and the push plate 14 to reset, and this is repeated to achieve the cyclic unloading of the workpiece after grinding.

[0022] In order to improve the stability of the device during operation, a pair of guide rods 21 are fixedly connected to the inner side of the fixed box 5 and penetrate the inner side wall of the sliding block 11, and the sliding block 11 is slidably connected to the outer wall of the guide rods 21; The guide rod 21 can guide the sliding block 11 when the reciprocating screw 10 rotates, thereby preventing the sliding block 11 from rotating together with the reciprocating screw 10 and improving the stability of the device during operation.

[0023] In order to ensure that the workpiece is accurately pushed into the material frame 8, a side plate 22 is fixedly connected to the top of the grinding table 1 and located at the end of the conveying mechanism 3, and a plurality of fixed seats 23 are fixedly connected to the side wall of the side plate 22. The inner sides of the plurality of fixed seats 23 are rotatably connected with rollers 24, and the outer sides of the rollers 24 are flush with the inner side of the material frame 8; By setting the side plate 22, the fixed seat 23 and the roller 24, a limiting effect can be exerted on the workpiece on the conveying mechanism 3, thereby preventing the workpiece from deviating after reaching the specified position, affecting the subsequent push plate 14 from accurately pushing the workpiece into the material frame 8, thereby improving the stability during the unloading process, and by setting the roller 24, it can roll with the movement of the workpiece, reducing friction when in contact with the workpiece, avoiding scratches on the workpiece, and improving the production quality of the workpiece.

[0024] In order to prevent the workpiece from falling directly to the bottom of the material frame 8 and causing damage, both sides of the material frame 6 are fixedly connected with mounting frames 25, the inner side of the mounting frames 25 is rotatably connected with adjusting rods 26, the outer wall of the adjusting rods 26 is fixedly connected with a gear ring 27, and both sides of the bottom plate 7 are fixedly connected with adjusting plates 28 and are arranged through the side walls of the material frame 6, and the adjusting plates 28 are provided with racks 29 meshing with the gear ring 27; Four oblique grooves 30 and four straight grooves 31 are equidistantly provided on the outer wall of the adjusting rod 26, and the two ends of the four oblique grooves 30 are respectively connected to the ends of two adjacent straight grooves 31, and the side walls of the mounting frame 25 and the upper and lower sides of the adjusting rod 26 are penetrated and slidably connected with straight plates 33, and the straight plates 33 are penetrated and slidably connected with round rods 34, and the side close to the round rods 34 is arranged on the inner side of the straight grooves 31, and the two sides of the sliding block 11 are fixedly connected with pressing blocks 36 and are arranged through the two sides of the fixed box 5; A recessed slot 32 is provided at the bottom of the four straight slots 31 and close to the gear ring 27, so that the connection between the slot 32 and the straight slot 31 has a step, and the connection between the slot 32 and the inclined slot 30 is inclined, a lower spring 35 is fixedly connected between the outer wall of the round rod 34 and the outer wall of the straight plate 33, a connecting plate 37 is fixedly connected between the straight plates 33, and a return spring 38 is fixedly connected between the connecting plate 37 and the outer wall of the mounting frame 25; The side walls of the mounting frame 25 are provided with through slots 39, the top of the adjusting plate 28 is fixedly connected with a fixing cover 40, the side wall of the fixing cover 40 and the through slot 39 are threadedly connected with a screw 41, the rack 29 is slidably connected to the inner side of the fixing cover 40, and the side wall of the screw 41 is rotatably connected to the side wall of the rack 29; When the unloading mechanism is in operation, the pressing block 36 will be driven to rotate and hit the connecting plate 37. When hitting the connecting plate 37, the straight plate 33 will be driven to slide at the same time, and the return spring 38 will be compressed, thereby driving the round rod 34 to slide in the straight groove 31. When the push plate 14 pushes the workpiece completely into the material frame 8, the pressing block 36 will push the round rod 34 to move above the card slot 32, and then the elastic force of the lower spring 35 will push the round rod 34 to insert into the card slot 32, and then the reciprocating screw 10 will drive the sliding block 11 and the pressing block 36 to reset, thereby gradually releasing the squeezing of the connecting plate 37, and then the elastic force of the return spring 38 will push the connecting plate 37 and the straight plate 33 to gradually slide outward; During this process, due to the step between the card slot 32 and the straight slot 31, the round rod 34 is restricted and squeezed into the inclined slot 30. The round rod 34 is restricted by the sliding of the straight plate 33 and cannot rotate. Therefore, it gradually squeezes the adjusting rod 26 to rotate, and at the same time drives the gear ring 27 to rotate, thereby driving the meshing rack 29 to move downward, and then drives the bottom plate 7 to slide downward through the adjusting plate 28, thereby driving the material frame 8 to slide downward, so that the workpiece just pushed in moves to the bottom of the upper surface of the grinding table 1, and then the round rod 34 moves out of the inclined slot 30 and slides to the next The rack 29 is pushed out of the meshing position with the toothed ring 27, and the bottom plate 7 is pushed upward to drive the rack 29 to move upward, so that the bottom plate 7 moves to the top of the material frame 6, and then the screw 41 is rotated in the opposite direction to pull the rack 29 to slide to the meshing position with the toothed ring 27, and the empty material frame 8 can be placed on the bottom plate 7, so that the material can be cyclically discharged.

[0025] In order to improve the stability of the material frame 8 during the placement process, a slot 42 is opened through the top of the bottom plate 7, and the wall of the material frame 8 is fixedly connected with an insert block 43 that is compatible with the slot 42. Through the setting of the slot 42 and the insert block 43, the longitudinal movement position of the material frame 8 can be restricted to avoid pushing the material frame 8 to move during the unloading process, thereby improving the stability of the device during operation.
