Description

Technical Field

[0001] The invention belongs to the technical field of component surface treatment, and in particular relates to a component surface treatment mechanism used in mechanical manufacturing. Background Art

[0002] Blackening is a common method for surface treatment of mechanical parts. The principle is to produce an oxide film on the metal surface to isolate the air and achieve the purpose of rust prevention. Blackening can be used when the appearance requirements are not high. The surface blackening of steel parts is also called bluing. The commonly used methods of blackening are traditional alkaline heating blackening and later room temperature blackening. However, the room temperature blackening process is not very effective for low carbon steel. Alkaline blackening is subdivided into single blackening and double blackening. The main components of blackening liquid are sodium hydroxide and sodium nitrite. The temperature required for blackening is relatively high. A good surface can be obtained at about 135-155°C, but the time required is different.

[0003] When the pipe-like components in the prior art are subjected to blackening treatment in the reaction liquid, they are gathered together, and it is easy for the pipe-like components to fit and collide with each other and between the pipe-like components and the treatment box, which affects the contact reaction between the fittings and the reaction liquid, thereby making the blackening reaction of the pipe-like metal components uneven and affecting the effect of the blackening treatment.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] See also Figure 1-8As shown, the present invention is a surface treatment mechanism for parts used in mechanical manufacturing, comprising an upper box body 2, a pipe fitting 6, a turntable 9, a rotating column 10 and a lower box body 14, one end of the rotating column 10 is rotatably connected to the interior of the upper box body 2, and the rotating column 10 extends to the interior of the turntable 9, the turntable 9 is fixedly connected to the rotating column 10, a plurality of insertion holes 901 are provided on the top of the turntable 9, and a support assembly is provided above each insertion hole 901, the pipe fitting 6 is plugged into the inside of the insertion hole 901 through the support assembly, so that the pipe fitting 6 can be separated in the upper box body 2 for blackening treatment, avoiding the prior art that when the pipe-like parts are subjected to blackening treatment in the reaction liquid, the pipe fittings 6 and the pipe fittings 6 and the upper box body 2 are easily fitted and collided because they are gathered together, which affects the contact reaction between the fitting and the reaction liquid, thereby making the blackening reaction of the pipe-like metal parts uneven, affecting the effect of the blackening treatment;

[0033] The rotating disk 9 is provided with floating components located below the insertion holes 901. The floating components can make the pipe 6 float up and down, so that the bottom end of the pipe 6 will not be attached to other components, so as to avoid the bottom end of the pipe 6 not being able to fully contact and react with the reaction liquid. At the same time, the inner wall of the pipe 6 and the components of the supporting component will not always be attached to the same position, so that the inner wall of the pipe 6 can fully contact and react with the reaction liquid even if it is attached to the components of the supporting component.

[0034] The bottom of the upper box body 2 is fixedly connected to the lower box body 14, the lower end of the rotating column 10 passes through the lower box body 14 and is rotatably connected to the lower box body 14, a driving component is provided inside the lower box body 14, the lower end of the upper box body 1 is fixedly connected to the column 28, the other end of the column 28 is fixedly connected to the bottom plate 16, the bottom of the side wall of the upper box body 2 is also provided with a drainage hole 27, the top of the upper box body 2 is slidably connected to the cover plate 1, the driving component 6 can drive the turntable 9 to rotate, thereby driving the pipe fitting 6 to rotate. On the one hand, the reaction liquid can be stirred by the rotation of the pipe fitting 6 to improve the contact reaction effect between the reaction liquid and the pipe fitting 6. On the other hand, the contact reaction effect between the reaction liquid and the pipe fitting 6 will be further improved when the pipe fitting 6 rotates, thereby improving the effect of the blackening treatment of the pipe fitting.

[0035] The floating assembly includes a connecting tube 8, a connecting disk 5 and a water pipe 7. The upper end of the rotating column 10 is fixedly connected to and communicated with the connecting disk 5. The connecting tube 8 is provided with multiple and is respectively fixedly connected to the bottom of the corresponding socket 901. The diameter of the connecting tube 8 is larger than the diameter of the socket 901. Each connecting tube 8 is communicated with the connecting disk 5. The inner bottom end of the connecting tube 8 is fixedly connected with a bottom bin 802. The bottom bin 802 is set to be conical. The top of the bottom bin 802 is fixedly connected with a support platform 801. The conical bottom bin 802 can make the reaction liquid entering the connecting tube 8 gather at the drainage hole 808, so that the reaction liquid can be discharged from the connecting tube 8, and the reaction liquid is prevented from entering the support platform 801. The upper part of the support platform 801 is disc-shaped and located inside the socket 901. The gap between the socket 901 and the upper disc of the support platform 801 constitutes an annular gap, and the annular gap is used to blow out airflow to push the pipe 6 to float up and down.

[0036] The floating assembly also includes a ring plug 806, which is slidably fitted in the annular gap. The ring plug 806 is made of magnetic material. The top ends of both sides of the ring plug 806 are fixedly connected with push rods 809. The push rods 809 are provided to allow a gap between the pipe fitting 6 and the ring plug 806, so that the airflow can form a thrust on the bottom end of the pipe fitting 6. The ring plug 806 is used to prevent the pipe fitting 6 from being inserted into the insertion hole 901 and descending a large distance inside the connecting tube 8 through the annular gap, thereby making it difficult for the airflow to push the pipe fitting 6 out. If the ring plug 806 is not provided, the pipe fitting 6 will descend to the bottom of the bottom bin 802. At this time, when the connecting tube 8 is ventilated, the air pressure will generate a lateral thrust on the inner wall of the pipe fitting 6, making it difficult for the pipe fitting 6 to move upward. When the ring plug 806 is provided, the descending distance of the pipe fitting 6 is short, and the air pressure will generate an upward thrust on the bottom end of the pipe fitting 6. And it can push the pipe fitting 6 to float up and down; two electromagnets 803 are fixedly connected to the inner side wall of the connecting tube 8, and the outside of the electromagnet 803 is covered with an insulating layer. The bottom ends of the two sides of the ring plug 806 are respectively fixedly connected with sliding rods 805, and the lower ends of the sliding rods 805 are slidably connected with the electromagnet 803. The outer sleeve of the sliding rod 805 is provided with a spring 2 804, and the spring 2 804 is fixed between the electromagnet 803 and the ring plug 806. When the electromagnet 803 is energized, it can adsorb the ring plug 806, so that the pipe fitting 6 pushes the ring plug 806 to compress the spring 2 804 and move downward for a distance. After that, the ring plug 806 can continue to compress the spring 2 804 and be adsorbed by the electromagnet 803, thereby fixing the position of the ring plug 806 and preventing the ring plug 806 from moving up and down as the pipe 6 floats up and down, thereby affecting the pushing effect of the airflow on the pipe 6.

[0037] A through hole is provided in the middle of the support platform 801, and the support platform 801 is connected to the bottom bin 802. Two annular air grooves 810 are provided on the side wall of the support platform 801. Two baffle rings 807 corresponding to the annular air grooves 810 are slidably connected to the inner wall of the through hole of the support platform 801. A straight rod 812 is fixedly connected between the two baffle rings 807. A spring three 811 is fixedly connected to the upper end of the straight rod 812. When ventilation is provided in the bottom bin 802, the straight rod 812 can be pushed to compress the spring three 811 and move upward, so that the baffle ring 807 is separated from the air groove 810, and the air flow can flow out of the air groove 810. When there is no ventilation, the baffle ring 807 can block the air groove 810 under the action of the spring three 811 to prevent liquid from entering the support platform 801.

[0038] A bottom hole 808 is provided at the lower end of the side wall of the connecting cylinder 8, wherein four connecting cylinders 8 are connected to the water pump 4 through the bottom hole 808, the other end of the water pump 4 passes through the turntable 9 and is connected to the upper box body 2, and a water pipe 7 is connected between the connecting cylinders 8, and the four connecting cylinders 8 connected to the water pump 4 are connected to other connecting cylinders 8 through the water pipe 7. The water pump 4 can extract the reaction liquid entering the connecting cylinder 8 through the bottom hole 808 to prevent the reaction liquid from accumulating in the connecting cylinder 8 and entering the support platform 801.

[0039] The support assembly includes a support tube 3, a sleeve 302 and an airway 301. The support tube 3 is fixedly connected to the middle position of the upper end of the support platform 801. The airway 301 is provided inside the support tube 3. The sleeve 302 is fixedly connected to the outer wall of the support tube 3 and communicated with the airway 301. A slider 306 is slidably provided inside the sleeve 302. A spring 305 is fixedly connected to one end of the slider 306 located inside the sleeve 302. The other end of the spring 305 is fixedly connected to the side wall of the support tube 3. Two brackets 304 are fixedly connected to one end of the slider 306 located outside the sleeve 302. A sliding ball 303 is rotatably installed between the two brackets 304. The sliding ball 303 rolls and fits with the inner wall of the pipe 6. A connecting rod 308 is fixedly connected to the lower position inside the airway 301. The lower end of the connecting rod 308 is fixedly connected to the spring 3 811, and A slide groove 307 is provided at a position near the bottom of the support tube 3, and the retaining ring 807 is slidably matched with the slide groove 307. When there is no air pressure inside the sleeve 302, the spring 1 305 can drive the slider 306 to retract into the sleeve 302, so as to facilitate the pipe 6 to be sleeved inside the support tube 3. When there is air pressure inside the sleeve 302, the spring 1 305 will overcome the elastic force of the spring 1 305 and drive the slider 306 to move toward the inner wall of the pipe 6, so that the sliding ball 303 forms a guiding support for the pipe 6, so that the pipe 6 can float up and down stably to avoid the pipes 6 from fitting and colliding with each other. It is explained here that since the minimum air pressure inside the sleeve 302 is greater than the maximum elastic force of the spring 1 305, even if the air pressure inside the sleeve 302 changes, it will not affect the support of the sliding ball 306 for the pipe 6.

[0040] The driving assembly includes a motor 13, a gear 12 and a gear 3 26. A support 15 is fixedly connected to the inner side wall of the lower box body 14, the motor 13 is fixedly connected to the support 15, and a rotating shaft 11 is rotatably connected to the inner upper wall of the lower box body 14. The lower end of the rotating shaft 11 is fixedly connected to the output shaft of the motor 13, a gear 12 is fixedly connected to the side wall of the rotating shaft 11, and a gear 3 26 is fixedly connected to the side wall of the rotating column 10. The gear 12 is meshedly connected with the gear 3 26. The rotating shaft 11 is driven to rotate by the motor 13, the rotating shaft 11 drives the gear 12 to rotate, and the gear 12 drives the rotating column 10 to rotate through the gear 3 26, so that the rotating column 10 drives the turntable 9 and the pipe fitting 6 to rotate synchronously, stirs the reaction liquid, improves the contact reaction effect between the pipe fitting 6 and the reaction liquid, and improves the effect of the blackening treatment of the pipe fitting.

[0041] The rotating column 10 extends to the inside of the shell 22 and is rotatably connected to the shell 22. The inner bottom wall of the shell 22 is rotatably connected with a rotating shaft 2 19 and a rotating shaft 3 24. The upper end of the rotating shaft 2 19 is fixedly connected to a baffle 17, and the baffle 17 is set to an elliptical shape. The baffle 17 slides and fits with the lower port of the rotating column 10. The side wall of the rotating shaft 2 19 is fixedly connected to a pulley 18. The upper end of the rotating shaft 3 24 passes through the shell 22 and extends to the outside and is fixedly connected to a gear 25. The gear 25 is meshed and connected with the gear 3 26. The side wall of the rotating shaft 3 24 is fixedly connected to a pulley 23. A belt 20 is rotatably installed between the pulley 23 and the pulley 1 18. An air pump 21 is fixedly connected to the inner bottom wall of the lower box body 14. The output end of the air pump 21 is connected to the inside of the shell 22. When the gear 3 26 rotates, it can be The gear 25 drives the rotating shaft 3 24 to rotate, and the rotation of the rotating shaft 3 24 drives the pulley 18 to rotate through the cooperation of the pulley 2 23 and the belt 20, and the rotation of the pulley 18 drives the rotating shaft 2 19 to rotate, and the rotating shaft 2 19 drives the baffle 17 to rotate. Since the baffle 17 is set to an elliptical shape, when the air pump 21 pumps air into the shell 22, when the baffle 17 rotates, the hollow setting inside the rotating column 10 will cause the air intake inside the rotating column 10 to change continuously, thereby changing the subsequent thrust on the pipe 6, so that the pipe 6 can float up and down due to the change in thrust, so that the fitting position of the pipe 6 and the sliding ball 303 can be continuously changed, avoiding the fitting position of the pipe 6 and the sliding ball 303 being fixed, resulting in the inner wall fitting of the pipe 6 being unable to fully contact with the reaction liquid, affecting the effect of the blackening treatment.

[0042] First, insert each pipe fitting 6 into each support pipe 3, then start the air pump 21, the air flow passes through the rotating column 10, the connecting plate 5, the bottom bin 802, and then enters the inside of the support platform 801, the air flow will push the straight rod 812 to compress the spring 3 811 to move upward, so that the retaining ring 807 is separated from the air groove 810, and the air flow can flow out of the air groove 810 and enter the space between the connecting tube 8 and the bottom bin 802, and at the same time press the pipe fitting 6, the pipe fitting 6 pushes the top rod 809 to drive the ring plug 806 to be separated The electromagnet 803 overcomes the elastic force of the spring 804 to adsorb and fix the ring plug 806, thereby fixing the position of the ring plug 806 to prevent the ring plug 806 from moving up and down with the up and down floating of the pipe 6, thereby affecting the pushing effect of the airflow on the pipe 6. The water pump 4 extracts the reaction liquid entering the connecting tube 8 through the bottom hole 808, and the airflow also enters the sleeve 302 through the airway 301, thereby pushing the slider 306 to drive the sliding ball 303 to stick to the inner wall of the pipe 6. The pipe 6 is supported by the motor 13, and the shaft 11 is driven to rotate by the motor 13, and the shaft 11 drives the gear 12 to rotate. The gear 12 drives the rotating column 10 to rotate through the gear 3 26, so that the rotating column 10 drives the turntable 9 and the pipe 6 to rotate synchronously to stir the reaction liquid, thereby improving the contact reaction effect between the pipe 6 and the reaction liquid, and improving the effect of the blackening treatment of the pipe. At the same time, the baffle 17 can be driven to rotate by the cooperation of the gear 3 26, the shaft 3 24 and other structures, thereby changing the air intake inside the rotating column 10, so that the pipe 6 can float up and down due to the change of thrust, so that the fitting position of the pipe 6 and the sliding ball 303 can be continuously changed, avoiding that the fitting position of the pipe 6 and the sliding ball 303 is fixed, resulting in the inner wall fitting of the pipe 6 being unable to fully contact with the reaction liquid, affecting the effect of the blackening treatment, after the blackening treatment of the pipe 6 is completed, the reaction liquid can be discharged through the drainage hole 27, and the cover plate 1 can cover the upper port of the upper box body 2 to avoid splashing of the reaction liquid.
