Description

Technical Field

[0001] The utility model relates to the field of aluminum oil cylinders for impact rammers, in particular to a rotary spray-shielding protective tooling for facilitating plastic spraying of aluminum oil cylinders for impact rammers. Background Art

[0002] A rammer is a compacting machine that compacts backfill soil layer by layer through impact and vibration. Gasoline rammers, also known as fire rammers, are used to compact and level asphalt gravel, concrete, and clay. They are particularly suitable for construction in environments such as buildings, ground surfaces, courtyards, roadbeds, bridge piles, trenches, and in the wild and confined spaces. They overcome the inconvenience of AC electric rammers in finding a power cord or their inability to operate without a power source. In particular, they overcome the safety risks associated with live electric rammers, making them suitable for construction tasks that large and medium-sized machines cannot accomplish.

[0003] Components of gasoline rammer: The overall composition of the rammer is mainly composed of the rammer plate, inclined block, aluminum cylinder, inner and outer cylinder sleeve components, elastic bellows in the lower part, and the speed change gear box assembly, clutch, engine, protective frame, shock-absorbing rubber pad, fuel tank and other sub-components in the upper part.

[0004] Working principle of impact rammer: Start the engine, and the engine output shaft is equipped with a clutch. The clutch is separated at a speed of 2200-2400r / min (the rated speed of a general impact rammer gasoline engine is 3600r / min). After the clutch is engaged, the small teeth in the gearbox are driven to rotate. The large and small gears cooperate, and the large gear reduces speed and increases torque. There is an eccentric shaft on the large gear, on which a connecting rod is assembled.

[0005] The horizontal rotation of the engine is converted into vertical up and down motion after passing through the gear box. The connecting rod is connected to the piston rod through the piston pin, acting on the spring in the inner cylinder sleeve. Below the inner cylinder sleeve are the inclined block and the ramming plate. The upper part of the rammer is equipped with a handrail protection frame to control the forward direction of the rammer. When working, the piston rod stretches the internal spring, and the rammer as a whole moves forward.

[0006] It jumps off the ground and, under its own weight, falls to the ground and tamps the soil. With each jump and fall of the rammer, the fuselage moves forward step by step.

[0007] At present, the aluminum cylinder blanks of one of the impact rammer parts of domestic manufacturers are generally painted first and then machined. However, many foreign customers require that the appearance treatment is not painted, and it needs to be electrostatically sprayed and then put into a high-temperature furnace for treatment. Since the aluminum cylinder has many processing surfaces, if it is directly sprayed, the plastic powder will enter the machined surface and affect the use of the workpiece. Therefore, the machined surface of the aluminum cylinder needs to be treated.

[0008] For protection and shielding, the aluminum cylinder body needs to be rotated during the spraying process, but there is currently no convenient rotating shielding tooling. Therefore, it is urgent to develop a rotating shielding protective tooling that is convenient for spraying the aluminum cylinder of the impact rammer to solve the above problems. Utility Model Content

[0009] The technical problem to be solved by the utility model is to provide a rotary shielding and protective tooling for facilitating plastic spraying of the aluminum oil cylinder of the impact rammer in view of the deficiencies of the prior art.

[0010] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0011] A rotary spray shielding protective tooling for convenient plastic spraying of an impact rammer aluminum cylinder is used for shielding the aluminum cylinder body during plastic spraying, comprising a top spray shielding cover plate, a main support frame, a main support plate, a rotating shaft and a rotating support assembly; the main support frame is connected to the bottom of the main support plate, the rotating shaft is welded to the center position of the main support plate, the rotating support assembly is rotatably sleeved on the rotating shaft, a connecting hole is opened at the top of the rotating support assembly, the bottom of the aluminum cylinder body is connected to the connecting hole, the top spray shielding cover plate is arranged at the top of the aluminum cylinder body, and the diameter of the top spray shielding cover plate is larger than the diameter of the top of the aluminum cylinder body.

[0012] The utility model includes components such as a top spray shielding cover plate, a main support frame, a main support plate, a rotating shaft and a rotating support assembly. The top spray shielding cover plate is arranged on the top of the aluminum cylinder body to prevent plastic powder from entering the machined surface on the top of the aluminum cylinder body and the interior of the aluminum cylinder body during plastic spraying, while the machined surface at the bottom of the aluminum cylinder body enters the rotating support assembly. While the rotating support assembly blocks the machined surface at the bottom of the aluminum cylinder body, it can also realize the function of rotation, which is convenient for spraying.

[0013] It effectively protects the machined surface of the aluminum cylinder from being contaminated by plastic powder. The operator can rotate the tooling while spraying until the spraying is completed. This structure saves labor, is easy to operate, has high production efficiency, and improves the benefits of the factory.

[0016] The bottom sealing plate, side sealing plate and top sealing plate form a boxed structure, forming a shielding and accommodating space for the machined surface at the bottom of the aluminum oil cylinder body. Since the bottom sealing plate is connected to the rotating sleeve through the rotating support plate, and the rotating sleeve is rotatably sleeved on the rotating shaft, when the operator sprays the plastic, the rotating side sealing plate can drive the aluminum oil cylinder body to rotate.

[0017] An armrest may be provided to facilitate rotation by the operator.

[0018] As a further preferred embodiment of the present invention, the first bearing and the second bearing are sleeved on the outside of the rotating shaft, and the rotating sleeve is sleeved on the outside of the first and second bearings. The arrangement of the first and second bearings effectively reduces the friction between the rotating sleeve and the rotating shaft, making the rotating sleeve rotate more smoothly.

[0019] As a further preferred embodiment of the present invention, a bolt and a nut are further included. A screw hole is formed transversely at the top of the rotating shaft, and the bolt passes through the screw hole and is fixed to the nut. The bolt and nut provided at the top serve as a limiter to prevent the rotating sleeve, the first bearing, or the second bearing from falling off from above the rotating shaft.

[0020] As a further preferred embodiment of the present invention, there are three main support frames, which are arranged in a conical shape at the bottom of the main support plate and have an equilateral triangle cross section. The conical shape of the main support frames ensures stable support while ensuring uniform force distribution.

[0021] As a further preferred embodiment of the present invention, the top spray cover further includes handles, which are arranged on both sides of the top spray cover.

[0022] It is convenient for operators to place the top spray cover.

[0025] As a further preferred embodiment of the present invention, the top sealing plate is detachably connected to the top of the side sealing plate.

[0026] The top sealing plate is detachably connected to the side sealing plate, which is convenient for replacing the top sealing plate with the corresponding connection hole size when spraying aluminum cylinder bodies of different sizes, thereby increasing the versatility of the tooling.

[0027] The utility model has the following beneficial effects:

[0028] The utility model comprises a top spray shielding cover plate, a main support frame, a main support plate, a rotating shaft and a rotating support assembly. The top spray shielding cover plate is arranged on the top of the aluminum oil cylinder body to prevent plastic powder from entering the machined surface on the top of the aluminum oil cylinder body and the interior of the aluminum oil cylinder body during plastic spraying, while the machined surface at the bottom of the aluminum oil cylinder body enters the rotating support assembly.

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and specific preferred embodiments.

[0038] In the description of the present invention, it should be understood that the terms "left side," "right side," "upper," "lower," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Terms such as "first" and "second" do not indicate the importance of a component and therefore should not be construed as limiting the present invention. The specific dimensions used in this embodiment are merely for illustrative purposes and do not limit the scope of protection of the present invention.

[0039] As shown in Figure 1-6, a rotary shielding protective tooling is provided for convenient plastic spraying of an impact rammer aluminum cylinder, which is used for shielding the aluminum cylinder body 2 during plastic spraying, and includes a top shielding cover plate 1, a main support frame 15, a main support plate 14, a rotating shaft 13 and a rotating support assembly; the main support frame 15 is connected to the bottom of the main support plate 14, the rotating shaft 13 passes through the circular hole in the center of the main support plate 14, and is welded after step positioning. The rotating support assembly can be rotatably sleeved on the rotating shaft 13, and a connecting hole is provided on the top of the rotating support assembly. The bottom of the aluminum cylinder body 2 is connected to the connecting hole, and the top shielding cover plate 1 covers the top of the aluminum cylinder body 2. The diameter of the top shielding cover plate 1 is larger than the diameter of the top of the aluminum cylinder body 2.

[0040] The present invention includes components such as a top spray shielding cover plate 1, a main support frame 15, a main support plate 14, a rotating shaft 13 and a rotating support assembly. The top spray shielding cover plate 1 is arranged on the top of the aluminum cylinder body 2 to prevent plastic powder from entering the machined surface on the top of the aluminum cylinder body 2 and the interior of the aluminum cylinder body 2 during plastic spraying, while the machined surface at the bottom of the aluminum cylinder body 2 enters the rotating support assembly. While the rotating support assembly blocks the machined surface at the bottom of the aluminum cylinder body 2, it can also realize the function of rotation, which is convenient for spraying.

[0041] It effectively protects the machined surface of the aluminum cylinder from being contaminated by plastic powder. The operator can rotate the tooling while spraying until the spraying is completed. This structure saves labor, is easy to operate, has high production efficiency, and improves the benefits of the factory.

[0042] The machined surface, i.e., the shielding surface 5, as shown in FIG2, includes the top shielding surface and the bottom shielding surface of the aluminum cylinder body 2. When plastic powder enters the machined surface, it will affect the use of the workpiece. Therefore, the machined surface of the aluminum cylinder needs to be protected and shielded.

[0043] The rotary support assembly includes a rotary sleeve 9, a rotary support plate 7, a bottom sealing plate 6, a side sealing plate 3 and a top sealing plate 4; the rotary sleeve 9 is rotatably sleeved on the rotary shaft 13, and the two ends of the rotary support plate 7 are fixedly connected to the outer side wall of the rotary sleeve 9 and the bottom surface of the bottom sealing plate 6 respectively; the side sealing plate 3 is welded to the four sides of the bottom sealing plate 6, the top sealing plate 4 is connected to the top of the side sealing plate 3, and the connecting hole is opened on the surface of the top sealing plate 4, the aluminum cylinder body 2 is connected to the top sealing plate 4 through the connecting hole, and the bottom spray shielding surface of the aluminum cylinder body 2 is located below the top sealing plate 4.

[0044] The bottom sealing plate 6, side sealing plates 3, and top sealing plate 4 form a box-like structure, creating a space to shield and accommodate the machined surface at the bottom of the aluminum cylinder body 2. Because the bottom sealing plate 6 is connected to the rotating sleeve 9 via the rotating support plate 7, and the rotating sleeve 9 is rotatably sleeved on the rotating shaft 13, the operator can rotate the side sealing plates 3 to drive the aluminum cylinder body 2 during plastic spraying. The side sealing plates 3 can also be provided with handrails to facilitate rotation.

[0045] The rotating sleeve 9 further includes a first bearing 8 and a second bearing 10, which are sleeved onto the exterior of the rotating shaft 13. The rotating sleeve 9 is sleeved onto the exterior of the first and second bearings 8 and 10. The arrangement of the first and second bearings 8 and 10 effectively reduces the friction between the rotating sleeve 9 and the rotating shaft 13, making the rotating sleeve 9 rotate more smoothly.

[0046] The rotating shaft 13 also includes a bolt 12 and a nut 11. A screw hole is provided transversely at the top of the rotating shaft 13, through which the bolt 12 passes and is secured to the nut 11. The bolt 12 and nut 11 at the top serve as position limiters, preventing the rotating sleeve 9, first bearing 8, or second bearing 10 from falling off the rotating shaft 13. Both the bolt 12 and nut 11 are M8.

[0047] There are three main support frames 15, each conically arranged at the bottom of the main support plate 14, with a cross-section that forms an equilateral triangle. This conical configuration ensures stable support and evenly distributes force. There are also three rotating support plates 7, symmetrically and vertically connected to the outer wall of the rotating sleeve 9 and the bottom surface of the bottom sealing plate 6.

[0048] The top spray cover 1 also includes handles located on both sides of the cover to facilitate placement. Anti-slip strips are located within the connection holes to increase friction between the machined surface at the bottom of the aluminum cylinder body 2 and the connection hole, preventing slipping.

[0049] The top sealing plate 4 is removably connected to the top of the side sealing plates 3. The size of the connection holes on the top sealing plate 4 matches the size of the spray-shielding surface at the bottom of the aluminum cylinder body 2. The removable connection of the top sealing plate 4 to the side sealing plates 3 facilitates replacement of the top sealing plate 4 with the corresponding connection hole size when spraying aluminum cylinder bodies 2 of different sizes, increasing the versatility of the tooling.

[0050] The structural assembly principle of this utility model:

[0051] The main support frame 15 is welded to the main support plate 14. The rotating shaft 13 passes through the circular hole in the center of the main support plate 14 and is welded after the step is positioned. The second bearing 10 is inserted into the rotating shaft 13, then the rotating sleeve 9, and the first bearing 8 is installed. The bolts 12 and nuts 11 are then installed in sequence in the upper end hole of the rotating shaft 13 as a stop. The lower and upper ends of the rotating support plate 7 are welded to the rotating sleeve 9 and the bottom sealing plate 6 respectively. The side sealing plates 3 are welded to the bottom sealing plate 6, and the top sealing plate 4 is detachably connected to the side sealing plates 3. The bottom shielding surface of the aluminum cylinder body 2 is inserted into the connection hole of the lower shielding plate 5. The top shielding plate 1 is then naturally placed above the aluminum cylinder body 2 to block the top shielding surface of the aluminum cylinder body 2.

[0052] The working principle of this utility model is:

[0053] First, place the spray shielding tooling in the electrostatic spraying production line. The bottom spray shielding surface of the aluminum cylinder body 2 is placed in the cavity formed by the bottom sealing plate 6, the side sealing plate 3 and the top sealing plate 4. Then, the top spray shielding cover plate 1 is naturally placed above the aluminum cylinder body 2. The top spray shielding cover plate 1 has a certain deadweight and a positioning device can be set to further prevent it from slipping.

[0054] During the spraying operation, the operator sprays the plastic powder while rotating the side cover plate 3 of the tooling. This drives the bottom cover plate 6, the rotating support plate 7, and the rotating sleeve 9 along the rotation axis 13, and the spraying tooling begins to rotate. When the spraying is complete, the aluminum cylinder body 2 is removed and ready for placement in the high-temperature furnace. The entire operation is very convenient and smooth, effectively preventing plastic powder contamination on the machined surfaces required by the customer, and the finished product has an excellent appearance.

[0055] The preferred embodiments of the present invention are described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and these equivalent transformations all fall within the scope of protection of the present invention.
