[0004] In the lifting spray cleaning system in the above-mentioned spray cleaning device, the nozzle is placed above the workpiece to be cleaned, and the workpiece is cleaned by high-pressure spraying from top to bottom. This spray cleaning system can only clean the surface of the workpiece, not the inner hole of the workpiece. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a motor shaft spray cleaning device to solve the problem that the existing spray cleaning device can only clean the outside of the workpiece but cannot clean the inner hole of the workpiece, resulting in insufficient cleaning.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A motor shaft spray cleaning device comprises a frame, a cleaning chamber with an operation window at the front end is provided on the frame, at least one shaft hole spray mechanism is installed in the cleaning chamber, the shaft hole spray mechanism is installed on the bottom plate of the cleaning chamber, and comprises a vertically arranged spray riser, the lower end of the spray riser is connected to an external liquid supply system, the pipe opening at the upper end of the spray riser is a high-pressure spray opening, and the pipe diameter of the spray riser is smaller than the aperture of the inner hole of the motor shaft to be cleaned; a workpiece positioning clamp is provided beside the pipe opening of each spray riser and on the side wall of the cleaning chamber, the workpiece positioning clamp is horizontally arranged, and comprises a left clamp block and a right clamp block, the left clamp block and the right clamp block are connected to a connecting rod mechanism, and can be opened or closed under the action of the connecting rod mechanism to form a motor shaft clamping opening. In this way, after adopting the above-mentioned cleaning device, when cleaning the shaft hole of the motor shaft, the shaft hole of the motor shaft can be directly aligned with the spray riser and sleeved on the spray riser, and then the upper end of the motor shaft is clamped and positioned by the workpiece positioning clamp. Finally, the control valve of the spray riser is opened, and high-pressure water is sprayed from the high-pressure spray port of the spray riser. After high-pressure spraying of the shaft hole, the purpose of cleaning is achieved. After spraying, water flows out from the lower end of the motor shaft and takes away the impurities in the shaft hole of the motor shaft, completing the cleaning. This method of directly setting the motor shaft sleeve on the spray riser for cleaning can continuously spray and flush the shaft hole of the motor shaft with high pressure, and the shaft hole is cleaned. At the same time, during cleaning, after being clamped by the workpiece positioning clamp, the motor shaft will not be offset, nor will it be in hard contact with the spray riser, thereby ensuring that the shaft hole of the motor shaft will not be scratched during cleaning.

[0008] Furthermore, a lifting platform is provided in the cleaning chamber, and a workpiece placement plate corresponding to the shaft hole spray mechanism is fixed above the lifting platform, a through hole for the spray riser to pass through is provided in the middle of the lifting platform, and a leakage hole for the spray riser to pass through is provided in the middle of the workpiece placement plate, and the aperture of the leakage hole is larger than the spray riser and smaller than the outer diameter of the workpiece to be cleaned. In this way, the lifting platform can be moved up and down and positioned in the height direction, so that the height of the lifting platform can be adjusted according to the length of the motor shaft to ensure that the workpiece positioning clamp can correspond to the upper end of the motor shaft and clamp the motor shaft to position it. The workpiece placement plate provided on the lifting platform can be lifted and lowered together with the lifting platform, and at the same time, it supports the workpiece to be cleaned. After the workpiece is placed, its leakage hole can allow the cleaned water to flow out and be led out through the bottom plate of the cleaning chamber.

[0009] Furthermore, a plurality of arc-shaped anti-collision blocks are arranged at intervals in the circumferential direction on the workpiece placement plate, and the arc-shaped anti-collision blocks are made of plastic or rubber, and a circular protective space is formed in the middle of the arc-shaped anti-collision blocks to match the workpiece to be cleaned. In this way, the arc-shaped anti-collision blocks can protect the outer wall of the workpiece to be cleaned, enclose the workpiece in the circular protective space, and together with the workpiece positioning clamp, form a positioning and protection for the workpiece.

[0010] Furthermore, the lifting platform is rectangular, and a threaded hole is provided around and in the middle of the lifting platform. An adjusting screw matched with the thread is sleeved in each threaded hole. The lower end of the adjusting screw is connected to the bottom plate of the cleaning chamber and matched with the thread of the adjusting nut to position the lifting platform. In this way, the lifting platform is lifted and lowered by adjusting the screw and the adjusting nut, and the structure is stable and the adjustment is relatively convenient.

[0011] Furthermore, the inner sides of the left clamp block and the right clamp block are each provided with a clamping opening, and the clamping opening is V-shaped or arc-shaped. Thus, when the clamping openings of the left and right clamp blocks are V-shaped, motor shafts of different diameters can be clamped, and when they are arc-shaped, they fit more closely with the motor shaft and clamp more tightly.

[0012] Furthermore, the cleaning chamber is rectangular, and transparent observation windows are provided on the left and right sides of the cleaning chamber. The bottom plate of the cleaning chamber is tilted toward the rear side, and a water guide port is provided at the rear end of the bottom plate, and the water guide port is connected to the liquid recovery tank through a pipe. In this way, the transparent observation window can be used to observe the internal cleaning situation, and the bottom plate is tilted to facilitate guiding and leading the liquid to the water guide port.

[0013] Furthermore, a plurality of radial spray holes are provided on the spray riser, and the spray riser is a stainless steel water pipe. In this way, the stainless steel water pipe has high strength and can meet the pressure requirements of high-pressure washing. After adding radial spray holes in the height direction, high-pressure water can be sprayed from other height positions, and the shaft hole can be cleaned more thoroughly.

[0014] Furthermore, a peripheral spray mechanism is provided above each shaft hole spray mechanism in the cleaning chamber, and the peripheral spray mechanism includes a high-pressure liquid pipe and a plurality of spray heads connected to the high-pressure liquid spray pipe. In this way, the peripheral spray mechanism can spray and rinse the outer wall of the motor shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figure 1-Figure 4 As shown, the motor shaft spray cleaning device provided in this embodiment includes a frame 1, a cleaning chamber 2 with an operation window at the front end is provided on the frame 1, at least one shaft hole spray mechanism 3 is installed in the cleaning chamber 2, the shaft hole spray mechanism 3 is installed on the bottom plate of the cleaning chamber 2, and includes a vertically arranged spray riser 31, the lower end of the spray riser 31 is connected to the external liquid supply system, the pipe mouth of the upper end of the spray riser 31 is a high-pressure spray mouth 32, and the pipe diameter of the spray riser 31 is smaller than the aperture of the inner hole of the motor shaft to be cleaned; a workpiece positioning clamp 4 is provided next to the pipe mouth of each spray riser 31 and on the side wall of the cleaning chamber 2, the workpiece positioning clamp 4 is horizontally arranged, and includes a left clamp block 41 and a right clamp block 42, the left clamp block 41 and the right clamp block 42 are connected to a connecting rod mechanism, and can be opened or closed under the action of the connecting rod mechanism to form a motor shaft clamping opening. After adopting the above-mentioned cleaning device, when cleaning the motor shaft hole, the motor shaft hole can be directly aligned with the spray riser 31 and sleeved on the spray riser 31, and then the upper end of the motor shaft is clamped and positioned by the workpiece positioning clamp 4, and finally, the control valve of the spray riser 31 is opened, and high-pressure water is sprayed from the high-pressure spray port 32 of the spray riser 31. After high-pressure spraying is performed on the shaft hole, the purpose of cleaning is achieved. After spraying, water flows out from the lower end of the motor shaft and takes away the impurities in the motor shaft hole, completing the cleaning. This method of directly arranging the motor shaft sleeve on the spray riser 31 for cleaning can continuously spray and flush the motor shaft hole with high pressure, and the shaft hole is cleaned. At the same time, during cleaning, after being clamped by the workpiece positioning clamp 4, the motor shaft will not be offset, nor will it be in hard contact with the spray riser 31, thereby ensuring that the motor shaft hole will not be scratched during cleaning.

[0022] In order to facilitate the cleaning of motor shafts of different lengths, a lifting platform 33 is also provided in the cleaning chamber 2. The lifting platform 33 is rectangular, and a threaded hole is provided around and in the middle of the lifting platform 33. An adjusting screw 34 is sleeved in each threaded hole and is threadedly matched with the adjusting screw 34. The lower end of the adjusting screw 34 is connected to the bottom plate of the cleaning chamber 2 and is threadedly matched with the adjusting nut 35 to position the lifting platform 33. Two workpiece placing trays 36 are fixed above the lifting platform 33. The workpiece placing trays 36 are fixed to the lifting platform 33 through a plurality of vertical rods. A through hole is provided in the middle of the lifting platform 33 for the spray vertical pipe 31 to pass through, and a water leakage hole is provided in the middle of the workpiece placing tray 36 for the spray vertical pipe 31 to pass through. The aperture of the water leakage hole is larger than the spray vertical pipe 31 and smaller than the outer diameter of the workpiece to be cleaned. The lifting platform 33 can be moved up and down in the height direction and positioned, so that the height of the lifting platform 33 can be adjusted according to the length of the motor shaft to ensure that the workpiece positioning clamp 4 can correspond to the upper end of the motor shaft and clamp the motor shaft. The workpiece placement plate 36 set on the lifting platform 33 can be raised and lowered together with the lifting platform 33, and at the same time, it supports the workpiece to be cleaned. After the workpiece is placed, its water leakage hole can allow the cleaned water to flow out and be led out through the bottom plate of the cleaning chamber 2.

[0023] During the cleaning process, the stability of the workpiece to be cleaned is still lacking if the workpiece positioning clamp 4 is used to clamp and position the workpiece to be cleaned. Based on this, a plurality of arc-shaped anti-collision blocks 37 are arranged at intervals in the circumferential direction on the workpiece placement plate 36. The arc-shaped anti-collision blocks 37 are made of plastic or rubber, and a circular protective space that matches the workpiece to be cleaned is formed in the middle of the arc-shaped anti-collision blocks 37. In this way, the arc-shaped anti-collision blocks 37 can protect the outer wall of the workpiece to be cleaned, enclose the workpiece in the circular protective space, and together with the workpiece positioning clamp 4, form the positioning and protection of the workpiece.

[0024] Specifically, the inner sides of the left clamp block 41 and the right clamp block 42 in the workpiece positioning clamp 4 are each provided with a clamping opening, and the clamping opening is V-shaped or arc-shaped. In this way, when the clamping openings of the left and right clamp blocks 42 are V-shaped, motor shafts of different diameters can be clamped, and when they are arc-shaped, they fit more closely with the motor shaft and clamp more tightly. In application, the opening and closing of the left clamp block 41 and the right clamp block 42 can also be controlled pneumatically.

[0025] The cleaning chamber 2 in this embodiment is rectangular, with transparent observation windows on the left and right sides of the cleaning chamber 2. The bottom plate of the cleaning chamber 2 is tilted toward the rear side, and a water guide port is provided at the rear end of the bottom plate, which is connected to the liquid recovery tank through a pipe. In this way, the transparent observation window can be used to observe the internal cleaning situation, and the bottom plate is tilted to facilitate guiding and leading the liquid to the water guide port.

[0026] In order to improve the cleaning effect, a plurality of radial spray holes are also provided on the spray riser 31, and the spray riser 31 is a stainless steel water pipe. In this way, the stainless steel water pipe has high strength and can meet the pressure requirements of high-pressure washing. After adding radial spray holes in the height direction, high-pressure water can be sprayed from other height positions, and the shaft hole can be cleaned more thoroughly.

[0027] Furthermore, a peripheral spray mechanism 5 is provided above each shaft hole spray mechanism 3 in the cleaning chamber 2, and the peripheral spray mechanism 5 includes a high-pressure liquid pipe and a plurality of spray heads connected to the high-pressure liquid spray pipe. In this way, the peripheral spray mechanism 5 can spray and rinse the outer wall of the motor shaft.

[0028] In addition, in actual application, in order to improve the cleaning effect, a wind shear mechanism for blowing high-pressure air to the motor shaft is also provided on the frame 1. The setting of the wind shear mechanism is prior art and will not be described in detail here.

The workpiece positioning clamp 4 in this embodiment can be a conventional manipulator, and the opening and closing of the left clamp block 41 and the right clamp block 42 are controlled by a motor or a starter.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the technical solution. Ordinary technicians in this field should understand that those modifications or equivalent replacements of the technical solution of the utility model without departing from the purpose and scope of the technical solution of the utility model should be included in the scope of the claims of the utility model.
