Description

Technical Field

[0001] The present invention relates to the technical field of reducers, and more specifically, to a housing finishing device for reducers. Background Art

[0002] The reducer housing is an important part of the reducer, which plays the role of fixing and protecting the internal parts of the reducer. The structural design of the housing has a significant impact on the working performance, processing technology, material consumption, quality and cost of the reducer. The housing is usually made of gray cast iron, which is suitable for mass production due to its good casting performance and vibration reduction performance. For reducers with heavy loads or impact loads, cast steel housing can also be used. The housing can be divided into split type and integral type in terms of structural form. The split surface of the split housing usually coincides with the plane of the axis of the transmission part.

[0003] The current speed reducer housing finishing devices on the market usually clean the dust on the surface of the speed reducer first, remove burrs and unevenness, place the speed reducer housing in the spraying device, use a fixed clamping mechanism to clamp the speed reducer housing, and then spray the speed reducer housing with colored dust. During spraying, a collection device will be placed under the speed reducer for reuse.

[0004] Because during the process of spraying colored dust on the reducer case, clamping the reducer case will cause the clamped part to be unable to be sprayed evenly, and because it is colored dust, when spraying the reducer case, it will be sprayed into the installation holes, causing subsequent installation problems, requiring secondary cleaning, and due to the special shape of the reducer case, during the spraying process, uneven spraying will occur, causing the problem of dust accumulation. Summary of the invention

[0045] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0046] See also Figure 1-13 , the present invention provides the following technical solutions:

[0047] In the first embodiment, during the processing of the reducer housing 2, the coloring dust is sprayed into the external air, and due to the granularity of the coloring dust, the working environment is polluted.

[0048] See also Figure 1 and Figure 2 A housing finishing device for a reducer includes a base unit 1, a reducer housing 2 is arranged in the middle position of the base unit 1, the base unit 1 provides an environment for spraying coloring dust for the reducer housing 2, and the base unit 1 provides an installation environment to collect excess dust sprayed to prevent the coloring dust from escaping in the air and affecting the working environment.

[0049] See also Figure 1 and Figure 2 The base unit 1 includes a supporting base 14, a material rack 13 is installed on one side above the supporting base 14, a material receiving rack 18 is installed on the other side above the supporting base 14, a collecting rack 11 is installed on the side of the material receiving rack 18 close to the material rack 13, and a mounting rack 12 is installed at the upper connection between the collecting rack 11 and the material rack 13.

[0050] See also Figure 2 and Figure 3 The support base 14 is used to provide installation conditions. A material rack 13 is installed on one side above the support base 14. The material rack 13 prevents the coloring dust from expanding outward and limits the dissipation area of ​​the coloring dust. A material collection rack 18 is installed on the other side above the support base 14. The material collection rack 18 is used to provide an installation environment and provide conditions for collecting coloring dust. A collecting rack 11 is installed on the side of the material rack 13 near the material rack 13. The collecting rack 11 cooperates with the material rack 13 to prevent the coloring dust from expanding outward. The mounting frame 12 connects the collecting rack 11 and the material rack 13 to form a rectangular structure to limit the dissipated coloring dust.

[0051] See also Figure 2 and Figure 3A wind collecting slot 15 is arranged on the top of the collecting rack 18, and the shape of the wind collecting slot 15 is circular. A fan 16 is arranged below the wind collecting slot 15, and a bellows 17 is installed at the output end of the fan 16. A collecting cylinder 19 is arranged equidistantly below the bellows 17.

[0052] See also Figure 2 and Figure 3 The air collecting slot 15 can provide the circulation conditions of the air flow. The shape of the air collecting slot 15 can pass a larger amount of air flow. The fan 16 rotates to drive the bellows 17 to exhaust air outside the air collecting slot 15. The collecting cylinders 19 are equidistantly arranged to filter the colored dust. The inwardly collected air flow is discharged through the bellows 17, and the colored dust adheres to the collecting cylinder 19.

[0053] See also Figure 2 and Figure 3 By setting a fan 16 to rotate and drive the bellows 17 to exhaust air outside the air collecting trough 15, collecting tubes 19 are equidistantly arranged to filter the colored dust. The air flow is discharged through the bellows 17, and the colored dust adheres to the collecting tube 19, thereby achieving the effect of collecting the scattered colored dust and limiting the dispersion of the colored dust.

[0054] In the second embodiment, due to the special shape of the reducer housing 2, uneven spraying may occur during the spraying process, and since colored dust is sprayed, if spraying is continued at one position, dust may accumulate in some areas.

[0055] See also Figure 1 and Fig. 9 A spray unit 4 is installed on one side of the inside of the base unit 1. The spray unit 4 can spray the outer wall of the reducer housing 2. The special structural design can spray to some dead corners that are difficult to handle. The spray unit 4 also includes a spray base 41. The spray base 41 is used to provide stable support and an installation environment. The spray base 41 is installed at the hollow bottom position of the base unit 1. A lifting arm 42 is installed above the spray base 41. The lifting arm 42 can adjust the up and down position of a swing arm 44. A swing arm 44 is rotatably installed above the lifting arm 42. The swing arm 44 can swing on the lifting arm 42. A rotating block 45 is installed at the output end of the swing arm 44, and the rotating block 45 can rotate on the swing arm 44.

[0056] See also Fig. 9 and Fig.10 A spray rod 43 is installed on the rotating block 45, and a spray mechanism 46 is installed at the output end of the spray rod 43. The spray mechanism 46 includes a spray bracket 461, which is connected to the spray rod 43. A driving mechanism 462 is installed below the spray bracket 461, and a rotating rod 464 is installed at the output end of the driving mechanism 462 through the spray bracket 461.

[0057] See also Fig. 9 and Fig.10 The spray unit 4 includes a spray mechanism 46, and the spray mechanism 46 includes a guide head 468. The guide head 468 is a right-angled trapezoid. The interior of the guide head 468 is hollow, and both ends of the guide head 468 are open. The shape design of the guide head 468 can allow the coloring dust to diffuse quickly to avoid clogging.

[0058] See also Fig. 9 and Fig.10 The length of the spray rod 43 can be extended into the side wall plywood of the reducer housing 2 for spraying. The spray mechanism 46 can spray the coloring dust onto the outer wall of the reducer housing 2 for coloring. The spray bracket 461 is used to provide an installation environment. The spray bracket 461 is connected to the spray rod 43 to provide a stable working environment. The driving mechanism 462 is composed of a motor and a motor box. The motor is installed in the motor box, and the output end of the motor is connected to the rotating rod 464.

[0059] See also Fig. 9 , Fig.10 and Fig.11 A connecting rod 463 is rotatably installed at one end of the rotating rod 464, a connecting column 469 is installed at one end of the connecting rod 463 away from the rotating rod 464, a first swing arm 465 is installed at one end of the connecting column 469 away from the connecting rod 463, the first swing arm 465 is installed below the spraying bracket 461, a second swing arm 467 is installed below the spraying bracket 461, the second swing arm 467 is meshed with one end of the first swing arm 465 close to the driving mechanism 462, the first swing arm 465 and the second swing arm 467 are both provided with a feeding port 466, and a guide head 468 is installed at one end of the first swing arm 465 and the second swing arm 467 away from the driving mechanism 462.

[0060] See also Fig.13 The guide head 468 is in the shape of a right-angled trapezoid. The guide head 468 is divided into two parts: a feed port and a spray port. The feed port of the guide head 468 is respectively connected to the first swing arm 465 and the second swing arm 467. The interior of the guide head 468 is hollow. The spray port of the guide head 468 is wider near the hypotenuse. The spray port of the guide head 468 is in an arc shape near the right-angled side. The angle of the arc is set to 35 degrees. This angle can not only make the discharge smoother, but also avoid accumulation at the spray port. Through the shape design of the spray port of the guide head 468, the effect of smoother discharge is achieved, and the accumulation of coloring dust clogging the spray port of the guide head 468 is reduced.

[0061] See also Fig. 9 , Fig.10 and Fig.11The feeding port 466 is used to insert the guide tube of the color dust. The color dust is respectively transported from the hollow position of the first swing arm 465 and the second swing arm 467 to the guide head 468. A nozzle is arranged inside the guide head 468. The nozzle is designed with a specific structure. When the color material passes through the nozzle, it will be split into fine particles due to shear force and pressure changes to form a mist. The color dust is transported to the nozzle. The guide head 468 can spray the color dust onto the outer wall of the reducer housing 2. The driving mechanism 462 drives the rotating rod 464 to rotate in the forward direction, and the connecting rod 463 rotates with the rotating rod 464. The connecting rod 463 rotates with The movable connecting column 469 rotates, and the rotation of the connecting column 469 drives the first swing arm 465 to approach the middle position of the spraying bracket 461. The rotation of the first swing arm 465 drives the second swing arm 467 to approach the middle synchronously. When the guide head 468 of the first swing arm 465 and the guide head 468 of the second swing arm 467 are in contact, the coloring powder can be sprayed in a concentrated manner. When the driving mechanism 462 reverses and drives the rotating rod 464 to rotate, the guide head 468 of the first swing arm 465 and the guide head 468 of the second swing arm 467 are separated, and diffuse spraying is performed, which can spray the gap of the raised part on the outer wall of the reducer housing 2.

[0062] The guide head 468 of the first swing arm 465 and the guide head 468 of the second swing arm 467 are fitted together, and the spray rod 43 enters the raised gap of the side wall of the reducer housing 2 to spray colored dust on the bottom of the gap. After spraying, the guide head 468 of the first swing arm 465 and the guide head 468 of the second swing arm 467 are separated, and the side walls on both sides of the gap are sprayed with colored paint respectively. The sprayed colored paint will not accumulate at the bottom of the gap, thereby achieving a uniform spraying effect.

[0063] By controlling the distance between the guide head 468 of the first swing arm 465 and the guide head 468 of the second swing arm 467, the device spraying mechanism 46 is switched between a concentrated spraying state and a diffuse spraying state. When the guide head 468 of the first swing arm 465 and the guide head 468 of the second swing arm 467 are in contact, the coloring powder can be sprayed in a concentrated manner. When the guide head 468 of the first swing arm 465 and the guide head 468 of the second swing arm 467 are separated, the spraying mechanism 46 can diffusely spray the coloring powder and then spray the gap of the raised part on the outer wall of the reducer housing 2, thereby achieving the effect of controlling the spraying area of ​​the sprayed coloring dust and avoiding excessive spraying at one location to cause accumulation.

[0064] Embodiment three, because in the process of spraying colored dust on the reducer housing, the existing reducer housing is clamped, usually using claws to clamp the two sides of the reducer housing. When spraying is required, the reducer housing needs to be removed and the clamping surface needs to be replaced, which reduces the work efficiency. In the process of replacing the clamping surface, the spraying clamping surface will be damaged. Since the clamping area of ​​the clamp is too large, the clamped part cannot be sprayed evenly during the spraying process. Moreover, since it is colored dust, when spraying the reducer housing, it will be sprayed into the installation holes, causing the problem of subsequent installation failure, and secondary cleaning is required.

[0065] See also Figure 1 , a lifting unit 3 is installed in the middle of the base unit 1, and a reducer housing 2 is installed in the middle of the lifting unit 3. The lifting unit 3 can provide support for the reducer housing 2 and can shield the part of the reducer housing 2 that does not need to be sprayed, thereby avoiding the need for secondary cleaning.

[0066] See also Figure 5 and Figure 6 The lifting unit 3 includes a plugging mechanism 31, which includes a plugging cylinder 313. The plugging cylinder 313 is installed above the base unit 1. The output end of the plugging cylinder 313 penetrates the base unit 1 and is equipped with a plugging plate 312, on which a plugging block 311 is installed.

[0067] See also Figure 5 and Figure 6 The top plug mechanism 31 can seal the reducer housing 2 from the top. The top plug cylinder 313 is installed on the mounting frame 12. The top plug cylinder 313 extends downward, driving the top plug plate 312 to approach the reducer housing 2. The top plug plate 312 drives the top plug block 311 to approach the reducer housing 2. The top plug block 311 enters the top notch of the reducer housing 2, and the top plug plate 312 seals the top of the reducer housing 2 without spraying.

[0068] See also Figure 5 and Figure 8 The lifting unit 3 also includes a lifting mechanism 33, which includes a lifting mounting frame 334. Four lifting fixing frames 335 are equidistantly arranged on the side of the lifting mounting frame 334. Lifting cylinders 337 are installed under the lifting fixing frames 335.
