DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0019] The service life of the cylinder body depends on the cleanliness, so it is very important to clean the cylinder body. At present, some horizontal cylinder bodies have long inner cavities, and problems such as surface oxidation and rust, external impurity invasion, burr generated during processing, etc. may occur in the inner cavities during the production process, so the inner cavities need to be cleaned in time to prolong the service life of the horizontal cylinder body. The traditional cleaning method is to configure a high-pressure water gun on a large water tank, and a bracket is configured above the water tank for storing workpieces. The inner cavity of the horizontal cylinder is flushed and cleaned by the worker holding the water gun. Such a cleaning method is to clean the inner cavity of the horizontal cylinder one by one by hand, which not only has low cleaning efficiency, but also has high labor intensity of the worker, and the cleaning degree is not enough, and the on-site operation conditions are also poor.

[0020] As Figure 1 , Figure 2As shown, according to an embodiment of the cylinder cleaning mechanism of the present application, it comprises a base 1, a water tank 2, a fixing mechanism 3, a cleaning mechanism 4, a cleaning rod 401, a through hole 4011, a driving mechanism 5, and a water supply mechanism 6. The water tank 2 is arranged on the upper part of the base 1, the fixing mechanism 3 is arranged in the water tank 2 and used for fixing the cylinder to be cleaned, the cleaning mechanism 4 is arranged in the water tank 2 and located opposite to the fixing mechanism 3, the driving mechanism 5 drives the cleaning mechanism 4 to clean the cylinder cavity, and the water supply mechanism 6 is connected with the cavity of the cleaning rod 401 and provides water source for the cleaning mechanism 4 to clean the cylinder.

[0021] According to the technical scheme of the present application, the cylinder cleaning mechanism is provided with the base 1, the water tank 2 is arranged on the upper part of the base 1, the fixing mechanism 3 and the cleaning mechanism 4 are arranged in the water tank 2 and located opposite to the fixing mechanism 3. The cleaning mechanism 4 comprises the cleaning rod 401 with a cavity, the side of the cleaning rod 401 is provided with the through hole 4011, the water supply mechanism 6 is connected with the cavity of the cleaning rod 401. The fixing mechanism 3 is used for fixing the cylinder, the driving mechanism 5 drives the cleaning rod 401 to move along the axial direction to the cylinder direction, so that the cleaning rod 401 can extend into the inside of the cylinder. At the same time, the water supply mechanism 6 provides cleaning water in the cavity of the cleaning rod 401, the water is sprayed out from the through hole by high pressure, and the cylinder inside is cleaned by cooperating with the movement of the cleaning rod 401. Through the above structure, the full-automatic cleaning of the cylinder can be realized, compared with the manual cleaning of the cylinder inside by the tool in the prior art, the cleaning efficiency is greatly improved, and the labor intensity is reduced. Therefore, the technical scheme of the present application solves the problems of low cleaning efficiency and large labor intensity of workers in the prior art.

[0022] As shown in Figure 1 and Figure 2 The base 1 is used for bearing other components, and in the embodiment, it is formed by square steel. The water tank 2 is arranged above the base, and the water tank 2 has an opening facing upward.

[0023] Further, the fixing mechanism 3, the cleaning mechanism 4 and the driving mechanism 5 are all arranged in the water tank 2. The fixing mechanism 3 is used for fixing the cylinder, that is, fixing the relative position of the cylinder in the water tank 2. The cleaning mechanism 4 comprises the cleaning rod 401, which has a long rod structure, a cavity and a through hole 4011 communicating with the cavity. The driving mechanism 5 can drive the cleaning rod 401 to relatively move along the axial direction. The water supply mechanism 6 can provide cleaning water to the cavity in the cleaning rod 401. The water tank 2 can bear and recycle the cleaned water, which is beneficial to the recycling of water.

[0024] When the cylinder is cleaned, the fixing mechanism 3 fixes the cylinder, and the cylinder is coaxial with the cleaning rod 401, and the opening of the cylinder faces the cleaning rod 401. Then the driving mechanism 5 drives the cleaning rod 401 to move along the axial direction, so that the cleaning rod 401 can extend into the inside of the cylinder. At the same time, the water supply mechanism 6 supplies water to the cavity of the cleaning rod 401 and enters the pressure, and the water is sprayed out from the through hole 4011 of the side wall of the cleaning rod 401, so as to clean the inner wall of the cylinder.

[0025] Further, the driving mechanism 5 can drive the cleaning rod 401 to reciprocate along the axial direction, so that the inner wall of the cylinder can be well cleaned.

[0026] It should be noted that the cavity of the cleaning rod 401 can also be connected to the gas, that is, the through hole 4011 of the cleaning rod 401 can also blow out the sweeping gas. On the one hand, the cleaning rod 401 can directly connect the gas to the cylinder, so as to blow out the foreign matters in the cylinder. On the other hand, the cleaning rod 401 can first connect the water to the cylinder for cleaning, and then connect the gas to blow dry the water stains.

[0027] Optionally, the through hole 4011 is a square long hole, and the through hole 4011 can be multiple, which are uniformly distributed on the end of the cleaning rod 401 in the circumferential direction. The multiple long holes can allow the water to fully wash in the inner cavity of the cylinder.

[0028] From Figure 6 It can be seen that the driving mechanism 5 specifically comprises a motor 501, a lead screw 502 and a sliding block 503. The lead screw 502 is rotatably arranged in the water tank, and the sliding block 503 is sleeved on the lead screw 502 through a threaded hole, that is, the lead screw 502 and the sliding block 503 are connected through a threaded pair, and the above-mentioned cleaning rod 401 is fixedly arranged on the mounting plate of the sliding block 503.

[0029] When the cylinder is cleaned, the motor 501 rotates to drive the lead screw 502 connected with the motor shaft to rotate, and the rotation of the lead screw 502 is converted through the threaded pair, so that the sliding block 503 moves linearly in the axial direction. The linear motion of the sliding block 503 can drive the cleaning rod 401 to move in a linear direction, so as to extend into the inside of the cylinder.

[0030] Further, the cleaning rod 401 is a long pipe with a cylindrical cross section, and the outer diameter of the cleaning rod 401 is smaller than the diameter of the inner cavity of the cylinder, so that the cleaning rod 401 can smoothly enter the cavity of the cylinder for cleaning. The design of the motor 501 and the lead screw and sliding block mechanism enables the cleaning rod 401 to repeatedly move linearly in the axial direction towards the cylinder in the water tank, so as to achieve the effect that the cleaning rod 401 repeatedly cleans the cavity of the cylinder, and improve the cleaning rate of the cylinder.

[0031] In some not shown embodiments, the driving mechanism can also be an oil cylinder or an air cylinder, or even a handle wheel. The screw rod 502 nut mechanism is integrated with the oil cylinder or air cylinder, the screw rod 502 is arranged in the hollow piston rod, and the nut is embedded in the piston. When the rodless cavity or the rod cavity of the oil cylinder or air cylinder inputs pressure oil or compressed air, the piston is pushed to move, and since the nut is fixed with the piston, the nut will drive the screw rod 502 to rotate. When forward movement is needed, the rodless cavity of the oil cylinder or air cylinder inputs pressure and flow, pushing the piston to move forward, and the piston rod outputs thrust and speed, while the nut drives the screw rod to rotate, and the slider 503 drives the cleaning rod 401 to move. More simply, the handle wheel can be directly connected to the screw rod to control the movement of the cleaning rod 401 by rotating the screw rod through the handle wheel.

[0032] Further, as shown in Figure 6 , the driving mechanism 5 further includes a first pulley, a second pulley 504 and a transmission belt 505, the first pulley and the second pulley 504 are connected through the transmission belt 505, the first pulley is coaxially connected with the motor shaft of the motor 501, and the second pulley 504 is coaxially connected with the end of the screw rod 502. By controlling the size and transmission ratio of the first pulley and the second pulley 504, the motor 501 can control the rotation speed of the screw rod 502 to a greater extent, which makes the speed of the cleaning rod 401 better adjustable and controllable.

[0033] In some not shown embodiments, the driving mechanism can also be composed of a gear and a rack, the gear is a circular toothed part, and the rack is a long strip toothed part, the two transmit power through the meshing of teeth and teeth. When the rack moves linearly, it will drive the gear meshing with it to rotate, and the gear is connected with the screw rod 502 shaft, thereby driving the screw rod to rotate.

[0034] Optionally, as can be seen from Figure 4 , the driving mechanism 5 further includes a linear guide rail 506, and the cleaning mechanism 4 is movably arranged on the linear guide rail 506. Since the cylinder body is slender, the length of the cleaning rod 401 is also long enough. When the length of the cleaning rod is long enough, only fixing the head and tail of the cleaning rod 401 will make the middle part of the cleaning rod not supported, resulting in bending or deformation. The linear guide rail 506 provides support for the entire cleaning rod 401 to ensure that the cleaning rod 401 has a force point and will not bend and deform. The linear guide rail 506 can also make the cleaning rod 401 move along the linear axis, without producing stroke deviation.

[0035] From Figure 7It can be seen that the cleaning rod 401 is provided with a brush head 4012 at one end of the fixed mechanism 3, the brush head is conical, small in front and large in back, and the rear end is consistent with the size of the cleaning rod 401, which is more beneficial to the brush head 4012 entering the cylinder cavity for cleaning. The brush head 4012 can be detachably arranged on the cleaning rod 401, for example, the brush head 4012 is connected with the inner thread of the cleaning rod 401 through the outer thread, or is fixedly connected with the cleaning rod 401 through the buckle and the slot cooperation. The brush head 4012 can also be rotatably arranged at the end of the cleaning rod 401, for example, the head of the cleaning rod 401 is provided with a bearing, and the brush head 4012 is connected with the bearing to realize the rotatable arrangement of the brush head 4012 at the head of the cleaning rod 401. The side wall of the brush head 4012 is provided with a spray hole 4013, which can be a plurality of circular small holes. The water supply mechanism 6 provides high-pressure water to the cleaning rod 401, and the brush head 4012 rotates rapidly under the action of the high-pressure water. When the brush head 4012 enters the cylinder cavity, the spray hole 4013 on the brush head 4012 sprays high-pressure water, and the brush head 4012 rotates rapidly to better clean the burrs and impurities in the cylinder, thereby achieving deep cleaning of the cylinder cavity. Since the brush head 4012 is detachably arranged at the head of the cleaning rod 401, when the working time of the brush head 4012 is too long and the cleaning effect is not good, the brush head 4012 can be replaced in time to ensure the cleaning rate of the cleaning rod 401.

[0036] In some embodiments not shown, the brush head 4012 can also be a hard-bristle brush or a soft-bristle brush. The hard-bristle brush is used for processing burrs or surface oxidation rust in the cavity. The soft-bristle brush is used for oil in the cylinder cavity or other impurities.

[0037] Optionally, a position detection mechanism 7 is arranged in the water tank 2. When the cleaning rod 401 driven by the lead screw moves to the position detection mechanism 7, the motor reverses to drive the cleaning rod 401 to move reversely, so that the cleaning rod 401 repeatedly cleans the cylinder cavity to improve the cleaning rate of the cylinder.

[0038] Optionally, the position detection mechanism 7 can be a limit switch. The limit switch can be mechanical. When the sliding block 503 moves to a specified position, the sliding block 503 touches the limit switch, and the limit switch reverses the current through the control system to drive the motor 501 to reversely rotate the lead screw 502, and the lead screw 502 drives the sliding block 503 to move reversely, so as to control the cleaning mechanism 4 to repeatedly clean the cylinder. Further, the position detection mechanism 7 can also be an induction switch.

[0039] From Figure 4 and Figure 5As can be seen from the drawings, the fixing mechanism 3 comprises a plurality of clamping seats 301 arranged at intervals, which are arranged on the left side of the cleaning rod 401 and the left side in the sink 2, and are arranged at opposite positions of the cleaning rod. Before cleaning, the clamping seats 301 clamp the head and tail of the cylinder through elastic blocks and handle clamping cylinders, and the clamped cylinder is coaxially aligned with the cleaning rod 401, so that the cleaning rod 401 always remains stable and aligned when moving towards the cylinder. The clamping seat 301 is provided with an inductive switch, which can determine whether the cylinder is clamped. When the cylinder is clamped completely, the motor 501 is started to clean the inner cavity of the cylinder through the cleaning rod 401. After cleaning, the clamping device is loosened, and the cleaned cylinder is taken out to complete the whole cleaning process.

[0040] In some embodiments shown, the fixing mechanism 3 can also be a hydraulic clamping device, a manual clamping device, etc. The hydraulic clamping device clamps the cylinder through the pressure generated by the hydraulic system. The clamping force generated by the hydraulic system is larger and more stable, and the size of the clamping force can be accurately controlled, so that the cylinder can be clamped and positioned accurately in the sink. The manual clamping device can be a screw clamping device. The screw clamping device clamps the cylinder by rotating the screw rod to push the clamping element. It has the advantages of simple structure, reliable clamping, good universality, good self-locking performance due to small screw helix angle, large clamping force and clamping stroke, and low cost.

[0041] Further, as can be seen from Figure 1 、 Figure 2 and Figure 3 , the water supply mechanism 6 is arranged at the right rear of the base 1. The water supply mechanism 6 comprises a sewage tank 601, a clean water tank 602 and a water pump 604. The sewage tank 601 is square and communicates with the sink 2. The sewage tank 601 is connected with the clean water tank 602 through a filtering structure 603. The water supply mechanism 6 forms high pressure through the water pump 604 to supply water to the cleaning rod 401. The water is sprayed from the through hole 4011 at the end of the cleaning rod 401 through high pressure. The sewage after cleaning the cylinder is returned to the sewage tank 601 through the sink. The sewage is filtered through the filtering structure 603 to filter out the particulate impurities such as burrs in the water. The filtered water is purified by the water purification mechanism to remove the solute such as oil stains, and then passes through the water pump 604 and the valve group to provide high pressure clean water for the cleaning rod 401. The clean water enters the cleaning rod 401 again, so that the water can be recycled. By regularly replacing the filter element of the filtering structure 603, the problem of affecting the filtering efficiency due to impurity accumulation can be avoided.

[0042] Optionally, the filter structure 603 can be a magnetic filter and / or a bag filter. The magnetic filter generates a strong magnetic field inside. The sewage in the sewage tank 601 passes through the inside of the magnetic filter. The iron-containing particles in the sewage are magnetized in the magnetic field and are firmly adsorbed on the magnetic filter core under the action of the magnetic field force. Then, the filtered liquid is discharged. When the adsorbed impurities reach a certain amount, the magnetic force needs to be eliminated or the power needs to be turned off. Then, the adsorbed impurities are cleaned. The filtering capacity of the magnetic filter is restored by restoring the magnetism. The iron particles can be efficiently removed by magnetic filtration. The magnetic rod or magnetic barrel used for adsorption can be repeatedly cleaned and used, which is more conducive to cost saving. The liquid filtered by the magnetic filter flows to the bag filter. The bag filter is mainly composed of a filter and a filter bag. The filter bag is mainly used to retain solid particles of different particle sizes in the fluid by using a bag-shaped structure made of fiber material. The liquid enters the filter and flows to the filter bag. The liquid passes through the pores in the filter bag. The particles larger than the pores are retained on the surface of the filter bag or in the grid of the fiber net, so as to filter the liquid. The bag filter can filter various types of particle impurities such as iron, copper, aluminum, sand, organic matter, etc. and is not limited by the magnetism of the material. The precision of the filter bag can be flexibly selected, from micrometer particles to coarse sand, etc. When the pressure difference between the inside and outside of the filter bag or the surface blockage is serious and reaches a set value or affects the flow, the machine needs to be stopped, the filter opened, the dirty filter bag taken out and discarded, and a new filter bag replaced. The bag filter can handle a large flow, and the cost of the filter bag itself is relatively low. It is very suitable for large flow and low impurity load conditions. Moreover, the process of replacing the filter bag is relatively simple and fast, and easy to operate. For particles of a target particle size, a suitable filter bag can be selected, and a single filtration can achieve a high removal rate. In this embodiment, the combination of magnetic filtration and bag filtration is used. The magnetic filter is used as a pre-treatment device to filter out a large amount of ferromagnetic impurities in the sewage. This can greatly reduce the burden on the subsequent bag filter. The remaining non-magnetic impurities and smaller particles are removed by the bag filter. This combination of magnetic filtration and bag filtration can not only take advantage of the low-cost treatment of iron filings by magnetic filtration, but also take advantage of the wide spectrum of bag filtration. Finally, the fluid is deeply purified, the service life of the filter bag is prolonged, and the overall filtration cost is reduced.

[0043] Optionally, from Figure 4 It can be seen from the above that the fixing mechanism 3 can be multiple. The multiple fixing mechanisms 3 are arranged along the width direction of the water tank 2 at intervals. The fixing mechanism 3 is arranged at the head and tail of the cylinder body. The cleaning mechanism 4 can be multiple. The multiple cleaning mechanisms 4 are arranged along the width direction of the water tank 2 at intervals. The multiple fixing mechanisms 3 and the multiple cleaning mechanisms 4 are arranged one by one. In this way, multiple layouts according to cleaning needs can be achieved. Not only can a large number of workpieces be loaded and cleaned, but also a small number of workpieces or even a single workpiece can be cleaned. This can not only improve work efficiency, but also save resources in the cleaning of a small number of workpieces.

[0044] While embodiments of the present application have been described in conjunction with the appended drawings, various modifications and changes can be suggested by persons skilled in the art, and all such modifications and changes are believed to fall within the scope of the present application as defined by the appended claims.
