Abstract
Description
Technical Field
[0001] This invention relates to the field of bearing ring heat treatment equipment, specifically to a salt cleaning machine and bearing ring heat treatment equipment. Background Technology
[0002] Currently, existing bearing rings require preliminary cleaning and salt cleaning before heat treatment, and then they are placed in an isothermal tempering furnace for tempering. If the salt cleaning process before tempering is not done properly, residual salts or oil stains will cause a series of quality problems during tempering (150~200℃, higher under special conditions) and subsequent processes. At best, it will affect the surface quality of the rings and increase processing costs; at worst, it will lead to internal structural defects in the rings and reduce the service life of the bearing.
[0003] Currently, bearing races can only be laid flat on the transmission mechanism of the salt cleaning machine to ensure stable transportation. However, the lower cleaning pipe at the bottom of the salt cleaning machine and the multiple nozzles above it are fixed in place. The cleaning agent sprayed from the upward nozzles is often blocked by the support components that have moved to the bottom, and cannot be sprayed directly upwards onto the bearing races. This results in liquid waste and reduces the cleaning efficiency of the bottom surface of the bearing races. Summary of the Invention
[0004] To address the aforementioned problems, this invention proposes a salt cleaning machine that solves the shortcomings of existing upward-spraying nozzles, where the cleaning agent is often blocked by the support components that move downwards, preventing it from being sprayed directly upwards onto the bearing races. This results in both liquid waste and reduced cleaning efficiency on the bottom surface of the bearing races.
[0005] The technical solution adopted in this invention is as follows:
[0006] A salt washing machine includes: a housing, a base inside the housing, a conveying mechanism on the base, the conveying mechanism including a transmission chain, a lower washing pipe assembly on the lower part of the side wall of the housing, a plurality of spaced-apart support assemblies on the transmission chain, the lower washing pipe assembly including a lower washing pipe located below the transmission chain, a plurality of self-adjusting mechanisms on the lower washing pipe, each self-adjusting mechanism including a movable plate installed inside the lower washing pipe, the movable plate dividing the lower washing pipe into an independent upper cavity and a lower cavity directly through which liquid flows, a rotating wheel in contact with the movable plate at the lower part of the movable plate, a transmission shaft at the center of the rotating wheel, a lever at the end of the transmission shaft, a first through hole at the end of the movable plate, a first nozzle on the lower washing pipe located at the first through hole, a horizontal plate fixedly connected to the lower washing pipe above the end of the movable plate, a second through hole on the horizontal plate, the lever deflecting to move the movable plate so that the first through hole and the second through hole are misaligned to reduce water flow into the first nozzle.
[0007] Optionally, the upper side wall of the housing is provided with an upper cleaning pipe assembly, which includes a horizontal cleaning pipe and a second nozzle is provided on the horizontal cleaning pipe.
[0008] Optionally, the movable plate has a hollow lower support frame at its end, and a sealing plate is installed on the upper part of the movable plate near the lower support frame to prevent water from entering the upper cavity. Alternatively, the end of the lever away from the transmission shaft is provided with a fixed shaft, which is inserted into the lever. A torsion spring is provided between the fixed shaft and the lever to provide the elastic force for the lever to return to its original position.
[0009] Optionally, the first nozzle is provided with spray holes arranged along the length of the lower cleaning pipe.
[0010] Optionally, a guide arc plate is provided on the outer periphery of the second through hole, and the guide arc plate is inclined upward.
[0011] Optionally, the lower part of the movable plate is provided with protruding meshing teeth, and the rotating wheel is provided with meshing grooves for the meshing teeth to engage.
[0012] Optionally, the meshing teeth are provided with a mounting groove, and the mounting groove is provided with iron protruding teeth.
[0013] Optionally, the mounting groove is provided with an elastic tension band, which connects the connecting teeth to the top surface of the mounting groove, and the bottom of the teeth is a protruding bottom surface.
[0014] Optionally, an electromagnetic component is provided on the outer circumference of the wheel, the electromagnetic component being used to generate magnetic force to attract the protruding iron teeth.
[0015] The present invention also discloses a bearing ring heat treatment equipment, including a salt cleaning machine, an upper unloading platform and a transmission platform located at the front end of the salt cleaning machine, wherein an air cooler is installed on the top of the transmission platform.
[0016] The beneficial effects of the present invention include at least the following:
[0017] 1. This invention reduces the water flow blocked by the support component, avoiding waste of cleaning fluid (mainly water). At the same time, the first nozzle of the self-adjusting mechanism that is not triggered by the support component (by moving the lever) sprays water with greater pressure and faster flow (because the water pressure in the lower cleaning pipe is constant), resulting in greater cleaning force on the bottom surface of the bearing ring and improving the cleaning efficiency of the bottom surface of the bearing ring (the side of the bearing ring that is placed flat on the support component and in close contact with the support component).
[0018] 2. The present invention has a simple structure and low cost, and is particularly suitable for harsh working environments with large water flow and high salt concentration (conventional optical counters or other electronic devices cannot work normally for a long time in such environments).
[0019] 3. In this invention, the guide arc plate guides the water flow to be sprayed obliquely upward, so that the water flow passing through the nozzle of the first nozzle avoids the support component approaching from left to right and is sprayed upward, avoiding water waste and cleaning more of the bearing rings on the side away from the support component, thus improving the cleaning efficiency of the bottom surface of the bearing rings (the side of the bearing rings that is placed flat on the support component and close to the support component).
[0020] 4. In this invention, when the electromagnetic component is energized, it generates magnetic force to attract the protruding iron teeth, causing the teeth to protrude towards the side of the electromagnetic component and fully engage with the meshing groove. This increases the meshing force between the teeth and the rotating wheel, preventing the water flow from having a large impact on the sealing plate, and thus pushing the movable plate to move earlier.

Detailed Implementation
[0035] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the invention.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0037] Example 1:
[0038] The technical solution adopted in this invention is as follows:
[0039] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention discloses a salt washing machine, comprising: a housing 1, a base 2 provided inside the housing, a conveying mechanism 3 placed on the base, a lower washing pipe assembly 4 provided on the lower part of the side wall of the housing, the conveying mechanism including a drive motor 5 and a transmission chain 6, a drive wheel 7 mounted on the output shaft of the drive motor, the drive wheel being connected to a driven wheel 8 via a belt, and a gear mounted on the output shaft of the driven wheel for driving the transmission chain to rotate.
[0040] The transmission chain is equipped with multiple spaced support components 9. The lower cleaning pipe assembly includes a lower cleaning pipe 10, which is located below the support components at the bottom of the transmission chain. The lower cleaning pipe is provided with multiple self-adjusting mechanisms 11. Each self-adjusting mechanism includes a movable plate 12 installed inside the lower cleaning pipe. The movable plate divides the lower cleaning pipe into an independent upper cavity 13 and a lower cavity 14. The end of the movable plate is provided with a hollow lower support frame 15. The lower part of the movable plate is provided with a rotating wheel 16 that contacts the movable plate. The center of the rotating wheel is provided with a transmission shaft 17, and the end of the transmission shaft is equipped with a lever 18.
[0041] like Figure 5 and Figure 6 As shown, a sealing plate 19 is installed on the upper part of the movable plate near the lower support frame to prevent water from entering the upper cavity. A first through hole 20 is provided at the end of the movable plate. A first nozzle 21 is provided on the lower cleaning pipe located at the first through hole. A horizontal plate 22 is provided above the end of the movable plate to fix the lower cleaning pipe. A second through hole 34 is provided on the horizontal plate.
[0042] The upper side wall of the housing is provided with an upper cleaning pipe assembly 23, which includes a horizontal cleaning pipe 24 and a second nozzle 25.
[0043] The end of the lever away from the drive shaft is provided with a fixed shaft 26. The fixed shaft is inserted into the lever. A torsion spring is provided between the fixed shaft and the lever. The torsion spring is used to provide the elastic force for the lever to return to its original position.
[0044] In this embodiment, the lever rotates relative to the fixed shaft, and the lever drives the transmission shaft to rotate synchronously.
[0045] The first nozzle is provided with nozzles 27 arranged along the length of the lower cleaning pipe.
[0046] like Figure 3 and Figure 4 As shown, the lower part of the movable plate is provided with protruding meshing teeth 28, and the rotating wheel is provided with meshing grooves 29 for the meshing teeth to engage.
[0047] In this embodiment, the distance between adjacent first nozzles is greater than the distance between support components, but is not an integer multiple of the distance between support components. The distance between the self-adjusting mechanisms (the distance between two adjacent levers) is greater than the distance between support components, but is not an integer multiple of the distance between support components.
[0048] like Figure 7 As shown, a represents the direction of movement of the transmission chain. When a pair of adjacent support components are in the first working position, one of the support components is close to the lever, and the adjacent support component (located at the rear end of the direction of movement of the transmission chain) does not block the first nozzle that cooperates with the lever.
[0049] like Figure 8 As shown, a represents the direction of movement of the transmission chain. When a pair of adjacent support components are in the second working position, one of the support components moves the lever, and the adjacent support component (located at the rear end of the direction of movement of the transmission chain) blocks the first nozzle that cooperates with the lever.
[0050] In this embodiment, the multiple self-adjusting mechanisms do not need to be set up for every adjacent pair of support components; they can be arranged at intervals as needed.
[0051] In this embodiment, the transmission chain moves, driving the support assembly to move. When the lower support assembly moves laterally to the lever, the lever is actuated, causing the rotating wheel to rotate and the movable plate to move, thus misaligning the first and second through holes to reduce water flow into the first nozzle. Since multiple nozzles remain fixed, when the support assembly actuates the lever, the corresponding first nozzles of adjacent support assemblies (located at the rear end of the support assembly's movement direction) gradually reduce water flow, eventually shutting off the water flow. This reduces the water flow blocked by the support assembly, avoiding waste of cleaning fluid. At the same time, the first nozzles of other self-adjusting mechanisms that are not triggered by the support assembly (by actuating the lever) spray higher water pressure and a faster flow (due to the constant water pressure in the lower cleaning pipe), resulting in greater cleaning force on the bottom surface of the bearing race and improving the cleaning efficiency of the bottom surface of the bearing race (the side of the bearing race that lies flat on the support assembly and is in close contact with the support assembly).
[0052] Example 2:
[0053] like Figure 9 As shown, the difference between Embodiment 2 and Embodiment 1 is that a guide arc plate 35 is provided on the outer periphery of the second through hole, and the guide arc plate is inclined upward.
[0054] In this embodiment, the guide arc plate guides the water flow to be sprayed obliquely upward, so that more of the water flow passing through the nozzle of the first nozzle avoids the support component approaching from left to right and is sprayed upward, avoiding water waste and cleaning more of the bearing rings on the side away from the support component, thus improving the cleaning efficiency of the bottom surface of the bearing rings (the side of the bearing rings that is laid flat on the support component and close to the support component).
[0055] Example 3:
[0056] like Figure 10 , Figure 11 and Figure 12 As shown, the difference between Embodiment 3 and Embodiment 1 is that the meshing teeth have a mounting groove 30, and the mounting groove has an iron protruding tooth 31. An elastic covering film is provided on the outer side of the mounting groove. The protruding tooth is connected to the top surface of the mounting groove by an elastic tension band 32, and the bottom of the protruding tooth is a protruding bottom surface. An electromagnetic component 33 is provided on the outer circumference of the rotating wheel, and the electromagnetic component is used to generate magnetic force to attract the protruding iron protruding tooth. A pair of terminals 36 are provided on the lever to connect to the electromagnetic component. The pair of terminals are connected to an external power source to power the electromagnetic component, and a control switch is connected in series between the external power source and the electromagnetic component. The elastic tension band provides a spring force that causes the protruding tooth to move away from the electromagnetic component.
[0057] In this embodiment, turning on the control switch energizes the electromagnetic component, generating magnetic attraction to the protruding iron teeth. These teeth protrude towards the electromagnetic component and fully engage with the meshing groove, increasing the meshing force between the teeth and the rotating wheel. This prevents excessive impact from the water flow on the sealing plate, thus allowing the movable plate to move earlier. Even with high water flow, turning on the switch maintains the normal operation of the self-adjusting mechanism.
[0058] Example 4:
[0059] The present invention also discloses a bearing ring heat treatment equipment, including a salt cleaning machine, an upper unloading platform and a transmission platform located at the front end of the salt cleaning machine, wherein an air cooler is installed on the top of the transmission platform.
[0060] The salt washing machine includes: a housing, a base inside the housing, a conveying mechanism placed on the base, a lower washing pipe assembly on the lower part of the side wall of the housing, multiple spaced-apart support assemblies mounted on the transmission chain, the lower washing pipe assembly including a lower washing pipe located below the support assemblies at the bottom of the transmission chain, multiple self-adjusting mechanisms on the lower washing pipe, each self-adjusting mechanism including a movable plate installed inside the lower washing pipe, the movable plate dividing the lower washing pipe into independent upper and lower cavities, and a hollow lower support frame at the end of the movable plate. The unit is equipped with a rotating wheel that contacts the movable plate. A drive shaft is located at the center of the rotating wheel, and a lever is installed at the end of the drive shaft. A sealing plate is installed on the upper part of the movable plate near the lower support frame to prevent water from entering the upper cavity. A first through hole is provided at the end of the movable plate. A first nozzle is provided on the lower cleaning pipe located at the first through hole. A horizontal plate is provided above the end of the movable plate to fix the lower cleaning pipe. A second through hole is provided on the horizontal plate. The movement of the transmission chain drives the support assembly to move and move the lever, which drives the rotating wheel to rotate, thereby driving the movable plate to move, so that the first through hole and the second through hole are misaligned to reduce the amount of water entering the first nozzle.
[0061] The conveying mechanism includes a drive motor and a transmission chain. The upper side wall of the housing is provided with an upper cleaning pipe assembly, which includes a horizontal cleaning pipe and a second nozzle on the horizontal cleaning pipe.
[0062] The end of the lever away from the drive shaft is provided with a fixed shaft, which is inserted into the lever. A torsion spring is provided between the fixed shaft and the lever, and the torsion spring is used to provide the elastic force for the lever to return to its original position.
[0063] In the implementation of this embodiment, the above description is only a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent structural transformations made based on the content of the present invention specification and drawings, whether directly or indirectly applied to other related technical fields, are similarly included within the scope of protection of the present invention.
