[0001] The utility model relates to the technical field of cylinder barrel production, in particular to an internal cleaning device for cylinder barrel production. Background Technique

[0002] A cylinder is a cylindrical metal part that guides a piston to perform linear reciprocating motion in the cylinder. Air expands in the engine cylinder to convert heat energy into mechanical energy; gas is compressed by the piston in the compressor cylinder to increase pressure. The housings of turbines, rotary piston engines, etc. are usually also called "cylinders".

[0003] During the production process of cylinders, dust and some iron filings will adhere to the inner wall of the cylinder barrel. In order to clean the dust, generally, workers will hold a cleaning brush to clean the inside of the cylinder barrel one by one, which is time-consuming and laborious, and it is easy to not clean thoroughly. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects of the prior art and provide an internal cleaning device for cylinder barrel production to solve the problems raised in the above background technique.

[0005] An internal cleaning device for cylinder barrel production includes a positioning mechanism for positioning the cylinder barrel and a cleaning mechanism for cleaning the inner wall of the cylinder barrel. The positioning mechanism includes a first positioning part, a second positioning part, a cylinder, a sliding seat and a guide rail. The first positioning part is installed on two sets of opposed guide rails. The second positioning part slides on the guide rail through the sliding seat, and one end of it can extend into the first positioning part. Two sets of cylinders are provided, and their output ends are fixedly connected to the second positioning part for driving the second positioning part to move. Multiple sets of first positioning holes are opened on the first positioning part, and multiple sets of second positioning holes are opened on the second positioning part. Each set of the first positioning holes and the second positioning holes are correspondingly arranged.

[0006] The cleaning mechanism includes an electric cylinder, a connecting shaft, a blowing head, an air inlet port, a cleaning cotton, a first gear, a toothed plate, a motor and a second gear. Two sets of electric cylinders are opposed to each other on both sides of the positioning mechanism. A support plate is installed at the output ends of the two sets of electric cylinders. Multiple sets of connecting shafts are rotatably installed on the support plate through bearings. The blowing head is connected and installed at the bottom of the connecting shaft. The cleaning cotton is arranged around the lower end of the connecting shaft. The first gear is fixedly installed at the upper end of the connecting shaft. Multiple sets of toothed plates are also provided and are respectively meshed with one side of the first gear. The second gear is meshed with one side of one set of toothed plates and is connected to the output end of the motor installed on the support plate.

[0007] Both the first positioning holes and the second positioning holes are arranged in an elliptical structure. The area where the first positioning holes and the second positioning holes overlap vertically is used to lock the cylinder barrel.

[0008] By adopting the above technical solution, the cylinder barrel can be automatically and quickly cleaned.

[0009] Multiple groups of the toothed plates are connected by connecting rods, and the connecting rods are supported by fixing columns on the support plates.

[0010] By adopting the above technical solution, the toothed plate can move normally, thereby driving the cleaning cotton to rotate and cleaning the inner wall of the cylinder barrel.

[0011] Three cleaning cottons are wound around the lower end of each group of connecting shafts, and there is a distance between the three cleaning cottons.

[0012] By adopting the above technical solution, it is convenient to clean the inner wall of the cylinder barrel.

[0013] The second positioning portion is horizontally supported by a sliding seat, and the opening of the first positioning portion facing the second positioning portion is adapted to the outer wall contour of the second positioning portion.

[0014] By adopting the above technical solution, the cylinder barrel is locked.

[0015] Both sides of one group of the toothed plates are provided with teeth. The teeth on one side are engaged with the first gear, and the teeth on the other side are engaged with the second gear.

[0016] By adopting the above technical solution, it is convenient to drive the toothed plate to move and drive the first gear to rotate.

[0017] The beneficial effects of the internal cleaning device for the production of the cylinder barrel of the utility model are as follows:

[0018] 1. By setting the positioning mechanism, the cylinder barrel is placed at the position where the first positioning hole and the second positioning hole are vertically aligned. Then, the cylinder can be driven to pull the second positioning portion to move along the guide rail through the sliding seat. At this time, the area where the second positioning hole and the first positioning hole are vertically aligned gradually shrinks, and the cylinder barrel can be locked on the positioning mechanism. This device is applicable to the positioning of cylinder barrels of different sizes, so as to facilitate the subsequent cleaning of multiple groups of cylinder barrels at the same time;

[0019] 2. By setting the cleaning mechanism, the electric cylinder can be driven to pull the support plate downward, so that the cleaning cotton penetrates into the inside of the cylinder barrel. Then, the external air pump is started to make the gas spray out from the air blowing head through the connecting shaft from the air inlet port to blow the inside of the cylinder barrel, and the motor is driven to drive the toothed plate to reciprocate through the second gear. Then, the toothed plate drives the connecting shaft to rotate through the first gear, and the connecting shaft synchronously drives the cleaning cotton to clean the inner wall of the cylinder barrel. Thus, the cylinder barrel is cleaned by gas blowing and the cleaning cotton. Description of the Drawings

[0025] The following elaborates on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0026] Refer to Figures 1-4 , an internal cleaning device for cylinder barrel production, including a positioning mechanism 1 for positioning the cylinder barrel and a cleaning mechanism 2 for cleaning the inner wall of the cylinder barrel. The positioning mechanism 1 includes a first positioning part 101, a second positioning part 102, a cylinder 103, a slide seat 104 and a guide rail 105. The first positioning part 101 is installed on two sets of opposing guide rails 105. The second positioning part 102 slides on the guide rail 105 through the slide seat 104, and one end of it can extend into the first positioning part 101. Two sets of cylinders 103 are provided, and their output ends are fixedly connected to the second positioning part 102 for driving the second positioning part 102 to move. Multiple groups of first positioning holes 1011 are opened on the first positioning part 101, and multiple groups of second positioning holes 1021 are opened on the second positioning part 102. Each group of the first positioning holes 1011 and the second positioning holes 1021 are correspondingly arranged;

[0027] Both the first positioning hole 1011 and the second positioning hole 1021 are arranged in an oval structure. The overlapping area of the first positioning hole 1011 and the second positioning hole 1021 up and down is used to lock the cylinder barrel. The first positioning hole 1011 is provided on both the upper surface and the lower surface of the first positioning part 101, and both the first positioning hole 1011 and the second positioning hole 1021 are preferably provided in five groups, and their structure is an oval structure. When the second positioning part 102 moves outward from the first positioning part 101, the space corresponding to the first positioning hole 1011 and the second positioning hole 1021 up and down becomes smaller and smaller, so as to lock the cylinder barrel. This setting can be applied to lock cylinder barrels of different sizes. (It should be noted that the sliding seat 104 is fixed at the bottom of the second positioning part 102. To ensure that the second positioning part 102 can move smoothly in the first positioning part 101, the sliding seat 104 is arranged at the side of the bottom of the second positioning part 102 away from the first positioning part 101). The second positioning part 102 is horizontally supported by the sliding seat 104, and the opening of the first positioning part 101 facing the second positioning part 102 is adapted to the outer wall contour of the second positioning part 102.

[0028] The cleaning mechanism 2 includes an electric cylinder 201, a connecting shaft 203, a blowing head 204, an air inlet port 205, a cleaning cotton 206, a first gear 207, a toothed plate 208, a motor 210 and a second gear 211. Two groups of electric cylinders 201 are placed on both sides of the positioning mechanism 1. A support plate 202 is installed at the output ends of the two groups of electric cylinders 201. Multiple groups of connecting shafts 203 are rotatably installed on the support plate 202 through bearings. The blowing head 204 is connected and installed at the bottom of the connecting shaft 203. Three cleaning cottons 206 are wound around the lower end of each group of connecting shafts 203, and there is a distance between the three cleaning cottons 206; the cleaning cotton 206 is wound around the lower end of the connecting shaft 203. The first gear 207 is fixedly installed at the upper end of the connecting shaft 203. The toothed plates 208 are also provided in multiple groups and are engaged with one side of the first gear 207 one by one. The second gear 211 is engaged with one side of one group of toothed plates 208 and is connected to the output end of the motor 210 installed on the support plate 202; the multiple groups of toothed plates 208 are connected by a connecting rod 209, and the connecting rod 209 is supported by a fixed column on the support plate 202; both sides of one group (preferably the middle group) of toothed plates 208 have teeth, one side of the teeth is engaged with the first gear 207, and the other side of the teeth is engaged with the second gear 211.

[0029] The connection between the fixed column and the connecting rod 209 is a movable connection. When the motor 210 drives the second gear 211 to rotate, the second gear 211 can drive the toothed plate 208 to move, and the toothed plate 208 is engaged with the first gear 207, so the connecting shaft 203 can be driven to rotate by the first gear 207.

[0030] Working principle: Place the cylinder barrel at the position where the first positioning hole 1011 and the second positioning hole 1021 are vertically aligned and overlapped. Then, the cylinder 103 can be driven to pull the second positioning part 102 to move along the guide rail 105 through the sliding seat 104. At this time, the overlapping area of the second positioning hole 1021 and the first positioning hole 1011 gradually shrinks, and the cylinder barrel can be locked on the positioning mechanism 1.

[0031] After the locking of the cylinder barrel is completed, the electric cylinder 201 can be driven to pull the support plate 202 downward, so that the cleaning cotton 206 extends into the interior of the cylinder barrel. Then, start the external air pump to make the gas be transported from the connecting shaft 203 to the blowing head 204 through the air inlet port 205 and spray out, so as to blow the interior of the cylinder barrel. At the same time, drive the motor 210 to drive the toothed plate 208 to reciprocate through the second gear 211. Then, the toothed plate 208 drives the connecting shaft 203 to rotate through the first gear 207. The connecting shaft 203 synchronously drives the cleaning cotton 206 to clean the inner wall of the cylinder barrel. Thus, the cylinder barrel is cleaned by gas blowing and the cleaning cotton 206.

[0032] It should be noted that the cleaning cotton 206 is detachably installed on the connecting shaft 203. This device can position cylinder barrels of different sizes. When the inner wall size of the cylinder barrel is large, the cleaning cotton 206 with a suitable size can be replaced to facilitate the cleaning of the inner wall of the cylinder barrel.

[0033] The above embodiments only represent several implementation manners of the present utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
