Description

Technical Field

[0001] This utility model relates to the field of shaft cleaning technology, specifically a multi-specification adjustable shaft spray cleaning machine. Background Technology

[0002] Shaft spray cleaning machines are automated cleaning equipment specifically designed for shaft workpieces. They utilize a high-pressure spray method to remove oil, iron filings, cutting fluid residue, dust, and other impurities from the surface and critical structures of shaft components, providing a clean workpiece surface for subsequent assembly, heat treatment, and plating processes. Widely used in automotive manufacturing, machining, bearing production, and agricultural machinery, the multi-specification adjustable shaft spray cleaning machine addresses the shortcomings of traditional shaft cleaning machines, which suffer from limited adaptability and poor adjustability. Its core feature is a multi-dimensional adjustable structure that allows for precise adaptation and efficient cleaning of shaft workpieces of different specifications, materials, and contamination levels, balancing cleaning quality, workpiece protection, and production flexibility. It is widely used in the post-processing cleaning of shafts in the automotive, machinery manufacturing, and bearing industries.

[0003] In existing technologies, workpiece positioning stability is extremely poor. Short shafts, unable to match the fixed support spacing, are prone to single-point support or suspension, resulting in violent shaking under high-pressure spraying and rotation, and even falling off and damaging equipment. Long shafts, on the other hand, only bear force at both ends, sag in the middle due to their own weight, disrupting coaxiality and creating cleaning blind spots. They can only barely accommodate shafts of a single length. When dealing with orders of multiple specifications, frequent manual adjustments of the shims are required. If the spray spacing is too close, the high-pressure water flow can easily scratch and erode the surface of the shaft, compromising precision. If the spacing is too far, the water flow impact force weakens, and stubborn contaminants such as oil and iron filings cannot be thoroughly removed. When dealing with shafts of different diameters, the fixed spacing cannot be adapted. Thin shafts are easily damaged by impact due to the close spacing, while thick shafts are not thoroughly cleaned due to the far spacing. To adapt to the fixed spacing, the water pressure needs to be forcibly adjusted: if the spacing is too close, the water pressure needs to be reduced, leading to a decrease in cleaning efficiency; if the spacing is too far, the water pressure needs to be increased, increasing the consumption of water, electricity, and cleaning agents. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-specification adjustable shaft spray cleaning machine to solve the problems mentioned in the background art, such as the inability to adjust the support according to the shaft length, which leads to frequent manual adjustment of the lining, reliance on manual loading and unloading, reduced turnover efficiency, and low equipment utilization.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-specification adjustable shaft spray cleaning machine, including a cleaning machine body, a support base fixedly connected to the bottom of the cleaning machine body, a water outlet pipe installed on the cleaning machine body, a closed door installed on the cleaning machine body, an operating table fixedly connected to the front of the cleaning machine body, a water storage box fixedly connected to the cleaning machine body, a cleaning component disposed inside the cleaning machine body, a drive component disposed inside the cleaning machine body, a support connecting frame fixedly connected inside the cleaning machine body, a rotating connecting shaft rotatably connected inside the support connecting frame, a first gear fixedly connected to the rotating connecting shaft, a rotating bracket rotatably connected inside the support connecting frame, a second gear fixedly connected to the rotating bracket, a rotating guide disc slidably connected to the rotating bracket, a fixed connecting block fixedly connected to the rotating guide disc, and a fixing bolt threadedly connected inside the fixed connecting block. The second gear meshes with the first gear, and the drive component drives the rotating connecting shaft to rotate inside the support connecting frame.

[0006] In the preferred embodiment of this technical solution, two rotating brackets are provided, and the two rotating brackets are symmetrically rotated and connected inside the support connecting frame.

[0007] In the preferred embodiment of this technical solution, two rotating guide disks are provided, and the two rotating guide disks are symmetrically and slidably connected on the rotating bracket.

[0008] According to the preferred embodiment of this technical solution, the drive component includes a first motor fixedly connected to the cleaning machine body, a first rotating sprocket fixedly connected to the output end of the first motor, a second rotating sprocket rotatably connected inside the cleaning machine body, a transmission chain connecting the first rotating sprocket and the second rotating sprocket, and the second rotating sprocket fixedly connected to the rotating connecting shaft.

[0009] In the preferred embodiment of this technical solution, the transmission chain has tooth grooves at corresponding positions of the teeth of the first rotating sprocket and the second rotating sprocket, and the teeth of the first rotating sprocket and the second rotating sprocket are meshed and connected inside the tooth grooves of the transmission chain.

[0010] According to the preferred embodiment of this technical solution, the cleaning component includes a fixed limiting rod fixedly connected inside the cleaning machine body, a sliding support rod slidably connected to the fixed limiting rod, a cleaning nozzle mounted on the sliding support rod, a cleaning water pipe connected between the water storage box and the cleaning nozzle, a drying structure mounted on the sliding support rod, an air inlet pipe provided on the drying structure, a second motor fixedly connected to the cleaning machine body, a rotating support rod fixedly connected to the output end of the second motor, an adjusting gear fixedly connected to the rotating support rod, a mounting fixing rod fixedly connected inside the cleaning machine body, and a sliding toothed plate slidably connected to the mounting fixing rod. The sliding toothed plate is meshed with the adjusting gear, and the sliding support rod is fixedly connected to the sliding toothed plate.

[0011] In the preferred embodiment of this technical solution, the sliding toothed plate has a groove at the corresponding position of the mounting rod, and the sliding toothed plate slides on the mounting rod through the groove.

[0012] Based on the preferred embodiment of this technical solution, a plurality of cleaning nozzles are provided, and the plurality of cleaning nozzles are evenly installed on the sliding support rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. By using two symmetrically arranged rotating supports, synchronous support is provided from both ends of the shaft-type workpiece, solving the tilting and swaying problem caused by single-sided support in existing technologies. This avoids collision and wear between the workpiece and equipment components, ensuring uniform spray coverage. The two sliding rotating guide discs can flexibly adjust their spacing. For short shafts, the spacing can be reduced to prevent suspension, and for long shafts, the support point can be optimized to prevent sagging in the middle. This solves the adaptation defects of traditional fixed supports for shafts of different lengths, ensuring good coaxiality of various shafts. With the fastening effect of fixed connecting blocks and fixing bolts, stable positioning of shafts of various specifications can be achieved without frequent manual adjustment of the shims. This eliminates the risk of workpieces falling and damaging the equipment, and avoids cleaning blind spots caused by improper support, significantly improving the equipment's adaptability to orders of various specifications.

[0014] 2. The meshing transmission between the sliding toothed plate and the adjusting gear, combined with the guiding action of the fixed limit rod, enables the smooth movement of the sliding support rod and cleaning nozzles. This allows for precise adjustment of the distance between the nozzles and the shafts, solving the problem of fixed distances being unsuitable for shafts of different diameters. For precision shafts, the distance can be increased to avoid impact damage, while for thick shafts heavily soiled, the distance can be reduced to enhance cleaning power. Several evenly distributed cleaning nozzles can form a multi-directional water flow coverage, effectively removing stains from complex structures such as shaft shoulders and keyways, eliminating the cleaning blind spots of traditional single nozzles. Simultaneously, the integrated drying structure introduces airflow through the air inlet pipe, allowing for rapid drying of workpieces after cleaning, reducing the risk of rust, improving production continuity, and eliminating the need for additional workpiece transfer for drying, thus improving overall cleaning efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5This utility model provides an embodiment including a cleaning machine body 1, a support base 2 fixedly connected to the bottom of the cleaning machine body 1, a water outlet pipe 3 installed on the cleaning machine body 1, a closed door 4 installed on the cleaning machine body 1, an operating table 5 fixedly connected to the front of the cleaning machine body 1, a water storage box 6 fixedly connected to the cleaning machine body 1, a cleaning component disposed inside the cleaning machine body 1, a drive component disposed inside the cleaning machine body 1, a support connecting frame 805 fixedly connected inside the cleaning machine body 1, a rotating connecting shaft 806 rotatably connected inside the support connecting frame 805, a first gear 807 fixedly connected to the rotating connecting shaft 806, a rotating bracket 809 rotatably connected inside the support connecting frame 805, a second gear 808 fixedly connected to the rotating bracket 809, and a rotating guide disc slidably connected to the rotating bracket 809. 810, a fixed connecting block 811 fixedly connected to the rotating guide disk 810, and a fixing bolt 812 threadedly connected inside the fixed connecting block 811; the second gear 808 meshes with the first gear 807; the rotating connecting shaft 806 is driven to rotate inside the support connecting frame 805 through the drive assembly; through the meshing transmission of the support connecting frame 805, the rotating connecting shaft 806, the first gear 807 and the second gear 808, and the fixing effect of the slidable rotating guide disk 810 on the rotating bracket 809 and the fixed connecting block 811 and the fixing bolt 812, flexible support and fixation of shafts of different lengths can be achieved. This ensures that the shafts rotate stably by relying on the rotating connecting shaft 806 during cleaning, and can also adapt to multiple specifications of shafts by adjusting the position of the rotating guide disk 810, solving the problem of single adaptability of traditional equipment and improving the adaptability of the equipment to multi-variety production.

[0019] Please see Figure 3 A further solution based on this embodiment is as follows: two rotating brackets 809 are provided, and the two rotating brackets 809 are symmetrically rotatably connected inside the support connecting frame 805. By symmetrically arranging two rotating brackets 809 inside the support connecting frame 805, support can be provided simultaneously from both ends of the shaft-like workpiece, ensuring that the workpiece is subjected to balanced force when rotating and cleaning with the rotating brackets 809, avoiding tilting and shaking caused by unilateral support, reducing collision and wear between the workpiece and components such as the rotating brackets 809, and ensuring uniform coverage of the spray water flow on the surface of the workpiece, thus improving cleaning consistency.

[0020] Please see Figure 3A further solution based on this embodiment is as follows: two rotating guide disks 810 are provided, and the two rotating guide disks 810 are symmetrically slidably connected to the rotating bracket 809. By symmetrically arranging two slidable rotating guide disks 810 on the rotating bracket 809, the distance between the two rotating guide disks 810 can be flexibly adjusted according to the length of the shaft workpiece, so that short shafts are not suspended due to excessive distance and long shafts are not drooping due to insufficient support, ensuring that various shafts maintain coaxiality under the support of the rotating guide disks 810, thereby improving the stability of the cleaning process and the protection effect on the workpiece.

[0021] Please see Figure 2 A further solution based on this embodiment is as follows: The drive assembly includes a first motor 801 fixedly connected to the cleaning machine body 1, a first rotating sprocket 802 fixedly connected to the output end of the first motor 801, a second rotating sprocket 803 rotatably connected inside the cleaning machine body 1, a transmission chain 804 drivingly connecting the first rotating sprocket 802 and the second rotating sprocket 803, and the second rotating sprocket 803 fixedly connected to the rotating connecting shaft 806. The first motor 801 drives the first rotating sprocket 802, and the transmission chain 804 drives the second rotating sprocket 803 and the connected rotating connecting shaft 806 to rotate. The transmission structure of the sprocket and the chain has a large torque and runs smoothly, which can ensure that shafts of different diameters maintain a stable speed under the drive of the rotating connecting shaft 806, avoid uneven cleaning caused by speed fluctuations, and extend the service life of the drive system.

[0022] Please see Figure 2 A further solution based on this embodiment is as follows: the transmission chain 804 has tooth grooves at corresponding positions of the teeth of the first rotating sprocket 802 and the second rotating sprocket 803. The teeth of the first rotating sprocket 802 and the second rotating sprocket 803 are meshed and connected inside the tooth grooves of the transmission chain 804. Through the precise meshing of the tooth grooves of the transmission chain 804 with the teeth of the first rotating sprocket 802 and the second rotating sprocket 803, slippage-free transmission is achieved, ensuring that the power of the first motor 801 is efficiently transmitted to the second rotating sprocket 803 and the rotating connecting shaft 806, avoiding the slippage problem of traditional belt drives, stabilizing the rotation speed of the shaft, ensuring uniform relative motion between the sprayed water flow and the workpiece surface, and improving the cleaning accuracy of precision shaft workpieces.

[0023] Please see Figure 4-5A further solution based on this embodiment is as follows: the cleaning component includes a fixed limiting rod 901 fixedly connected inside the cleaning machine body 1, a sliding support rod 902 slidably connected to the fixed limiting rod 901, a cleaning nozzle 904 installed on the sliding support rod 902, a cleaning water pipe 906 connecting the water storage box 6 and the cleaning nozzle 904, a drying structure 905 installed on the sliding support rod 902, an air inlet pipe 907 provided on the drying structure 905, a second motor 908 fixedly connected to the cleaning machine body 1, a rotating support rod 909 fixedly connected to the output end of the second motor 908, an adjusting gear 910 fixedly connected to the rotating support rod 909, and a fixedly connected... The main body 1 has an internal mounting rod 911 and a sliding toothed plate 912 slidably connected to the mounting rod 911. The sliding toothed plate 912 is meshed with the adjusting gear 910. The sliding support rod 902 is fixedly connected to the sliding toothed plate 912. The second motor 908 drives the adjusting gear 910 on the rotating support rod 909, which in turn drives the sliding toothed plate 912 on the mounting rod 911 and the connected sliding support rod 902 to slide along the fixed limit rod 901. This allows for precise adjustment of the distance between the cleaning nozzle 904 and the shaft, adapting to shafts of different diameters and contamination levels. At the same time, the air drying structure 905 and the air inlet pipe 907 work together to achieve rapid drying after cleaning, reducing the risk of rust and improving production continuity.

[0024] Please see Figure 4-5 A further solution based on this embodiment is as follows: the sliding toothed plate 912 has a groove at the corresponding position of the mounting rod 911. The sliding toothed plate 912 slides on the mounting rod 911 through the groove. The groove on the sliding toothed plate 912 and the mounting rod 911 cooperate to provide stable guidance for the sliding toothed plate 912, ensuring that it moves smoothly along a straight line under the drive of the adjusting gear 910. This avoids the sliding support rod 902 and the cleaning nozzle 904 from shifting or shaking during adjustment, ensuring the accuracy of the distance adjustment between the nozzle and the shaft, and improving the consistency of the cleaning effect.

[0025] Please see Figure 4-5 A further solution based on this embodiment is as follows: a plurality of cleaning nozzles 904 are provided, and the plurality of cleaning nozzles 904 are evenly installed on the sliding support rod 902. By evenly installing a plurality of cleaning nozzles 904 on the sliding support rod 902, the surface of shaft-type workpieces and complex structures such as shaft shoulders and keyways can be sprayed and impacted from multiple directions, effectively removing blind spots and impurities that are difficult to cover by a single nozzle; at the same time, the multi-nozzle design can reduce the water pressure of a single cleaning nozzle 904, reducing damage to the surface of the workpiece while ensuring cleaning efficiency, thus balancing cleaning effect and workpiece protection.

[0026] Working principle: First, adjust the position of the rotating guide plate 810 on the rotating bracket 809 according to the length of the shaft. The workpiece is clamped by the fixed connecting block 811 and the fixing bolt 812. The two symmetrical rotating brackets 809 provide stable support from both ends. In the drive assembly, the first motor 801 drives the first rotating sprocket 802, which drives the second rotating sprocket 803 and the rotating connecting shaft 806 to rotate via the transmission chain 804. The first gear 807 and the second gear 808 mesh to drive the workpiece to rotate synchronously and uniformly. During the cleaning stage, the cleaning fluid in the water storage box 6 is transported to the cleaning nozzle 904 through the cleaning water pipe 906. The second motor 908 drives the adjusting gear 910 on the rotating support rod 909, causing the sliding tooth plate 912 to slide along the mounting fixing rod 911, which drives the sliding support rod 902 and the cleaning nozzle 904 to move along the fixed limit rod 901, precisely adjusting the distance between the nozzle and the workpiece. Several evenly distributed cleaning nozzles 904 spray high-pressure water jets, which, in conjunction with the workpiece rotation, achieve full-surface cleaning without dead angles. After cleaning, airflow is introduced through the air inlet pipe 907, and the workpiece is quickly dried through the air drying structure 905. Wastewater is discharged through the outlet pipe 3. The entire process can be controlled via the operating console 5, the sealing door 4 ensures a sealed cleaning environment, and the support base 2 ensures stable operation of the equipment, ultimately achieving automated and high-precision cleaning of shafts of different specifications.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
