[0002] Vibrating sand machines are generally used in the manufacture of mechanical parts, especially for workpieces such as those in the water chamber after casting, where the sand is particularly difficult to remove. Incomplete sand removal affects the cleanliness of the engine, leading to a series of malfunctions in the engine and other equipment. Therefore, a vibrating sand machine is needed for this process. However, existing vibrating sand machines have some shortcomings, such as:

[0003] Application No. CN201921743025.5 describes a vibrating sander for removing core sand from cylinder blocks. This equipment not only meets the process requirements for removing sand from cylinder blocks, but also eliminates the need for operators to use hand hammers to perform secondary cleaning of residual molding sand and core sand. However, in actual use, due to the lack of a moving mechanism, it may be difficult to adjust the position of the workpiece, causing the equipment to shift when vibrating the workpiece, which may affect the vibration efficiency of the equipment.

[0004] Therefore, we propose an engine cylinder block vibratory sander to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide an engine cylinder block vibrating sander to solve the problem mentioned in the background art that most cylinder block vibrating sanders on the market currently lack a moving mechanism, making it difficult to adjust the position of the workpiece. This causes the equipment to deviate during the vibrating sanding process, which may affect the sanding efficiency of the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an engine cylinder block vibrating sander, comprising a clamping cylinder and a high-frequency vibrator, a central motorized roller conveyor disposed at the bottom of the high-frequency vibrator, the left end of the clamping cylinder being fixedly connected to the high-frequency vibrator, and a vibrating head being connected to the left end of the high-frequency vibrator, and a return spring being connected to the left end of the high-frequency vibrator; a crossbeam is connected to the top of the high-frequency vibrator, and the outer side of the return spring is fixedly connected to the crossbeam.

[0007] The bottom of the central motorized roller conveyor is equipped with a lifting cylinder, and a lifting guide column is provided on the outside of the lifting cylinder. The lifting cylinder can drive the central motorized roller conveyor to rise and fall to a designated position.

[0008] By setting up a central motorized roller conveyor, the equipment can move the workpiece to a designated position, and then use a lifting cylinder to drive the central motorized roller conveyor to rise and fall to the designated position. This ensures that the high-frequency vibrator will not cause workpiece deviation when driving the vibration head to perform sand removal on the workpiece. It can realize online streamlined and braking production, and ensure that the sand in the engine cylinder cavity is fully shaken off, perfectly solving the problem of online production of engine cylinder sand removal.

[0009] As a preferred technical solution of this utility model, the left end of the high-frequency vibrator is provided with two sets of fixed shafts, and the high-frequency vibrator is fixedly connected to the return spring through the fixed shafts.

[0010] The above technical solution enables the high-frequency vibrator to be more stable when connected with the return spring, thereby increasing the robustness of the equipment during operation.

[0011] As a preferred technical solution of this utility model, the high-frequency vibrator is located at the top of the central motorized roller conveyor, and a waste sand chute is provided at the bottom of the central motorized roller conveyor. The bottom of the waste sand chute is provided with a leakage hole. The bottom of the waste sand chute is fixedly connected to the lifting cylinder, and the top of the lifting guide column can fit in contact with the waste sand chute.

[0012] The above technical solution allows the shaken-off sand to fall into the waste sand chute, making it more convenient for the equipment to collect sand and other debris.

[0013] As a preferred technical solution of this utility model, an upper motorized roller conveyor is provided at the right end of the middle motorized roller conveyor, and a lower motorized roller conveyor is provided at the left end of the middle motorized roller conveyor. The upper and lower motorized roller conveyors are equipped with motors to drive the rollers to rotate.

[0014] The above technical solution makes feeding the equipment more convenient, thereby increasing the equipment's efficiency.

[0015] As a preferred technical solution of this utility model, the upper motorized roller conveyor and the lower motorized roller conveyor are located at the bottom of the crossbeam frame, and the clamping cylinder is fixedly connected to the top of the crossbeam frame.

[0016] The above technical solution makes it easier to fix the upper and lower motorized roller conveyors at both ends, thereby increasing the stability of the equipment during operation.

[0017] As a preferred technical solution of this utility model, a set of correction mechanisms is provided on each of the front and rear sides of the central motorized roller conveyor, and the correction mechanism includes a push cylinder, and a correction plate is connected to the inner side of the push cylinder.

[0018] The above technical solution makes it easier to adjust the position of the workpiece, thereby increasing the stability of the equipment during sand vibration.

[0019] As a preferred technical solution of this utility model, a drive motor is provided inside the central motorized roller conveyor, and a drive shaft is provided at the left end of the drive motor. A first bevel gear is provided on the outside of the drive shaft. A second bevel gear meshes with the rear end of the first bevel gear.

[0020] The above technical solution enables the rolling roller body inside the central motorized roller conveyor to be more stable during operation, thereby increasing the stability of the equipment during operation.

[0021] Compared with the prior art, the beneficial effects of this utility model are: by setting the central motorized roller conveyor, the equipment can move the workpiece to the designated position, and then drive the central motorized roller conveyor to rise and fall to the designated position through the lifting cylinder. This ensures that the high-frequency vibrator will not cause the workpiece to deviate when driving the shock head to perform sand removal work. It can realize online streamlined and braking production, and ensure that the sand in the inner cavity of the engine cylinder is fully shaken off, thus perfectly solving the problem of online production of engine cylinder sand removal.

[0022] Furthermore, by setting up a waste sand chute, the shaken-off sand can fall into the waste sand chute, making it more convenient for the equipment to collect sand and other debris.

[0023] Furthermore, the addition of a correction mechanism makes it easier to adjust the position of the workpiece, thereby increasing the stability of the equipment during sand vibration. Attached Figure Description

Please refer to [link / reference]. Figures 1-6 This utility model provides a technical solution: an engine cylinder block vibrating sander, including a clamping cylinder 1 and a high-frequency vibrator 2, a central motorized roller conveyor 7 set at the bottom of the high-frequency vibrator 2, the left end of the clamping cylinder 1 being fixedly connected to the high-frequency vibrator 2, and the left end of the high-frequency vibrator 2 being connected to a vibrating head 3, and the left end of the high-frequency vibrator 2 being connected to a return spring 5, the top of the high-frequency vibrator 2 being connected to a crossbeam frame 4, and the outer side of the return spring 5 being fixedly connected to the crossbeam frame 4;

[0033] The bottom of the central motorized roller conveyor 7 is equipped with a lifting cylinder 9, and a lifting guide column 10 is provided on the outside of the lifting cylinder 9. The lifting cylinder 9 can drive the central motorized roller conveyor 7 to rise and fall to a designated position.

[0034] Two sets of fixed shafts are provided on the left end of the high-frequency vibrator 2, and the high-frequency vibrator 2 is fixedly connected to the return spring 5 through the fixed shafts; the high-frequency vibrator 2 is located at the top of the middle motorized roller conveyor 7, and the bottom of the middle motorized roller conveyor 7 is provided with a waste sand chute 8, and the bottom of the waste sand chute 8 is provided with a leakage hole. The bottom of the waste sand chute 8 is fixedly connected to the lifting cylinder 9, and the top of the lifting guide column 10 can fit with the waste sand chute 8.

[0035] The upper motorized roller conveyor 6 is provided at the right end of the middle motorized roller conveyor 7, and the lower motorized roller conveyor 11 is provided at the left end of the middle motorized roller conveyor 7. The upper motorized roller conveyor 6 and the lower motorized roller conveyor 11 are equipped with motors to drive the rollers to rotate. The upper motorized roller conveyor 6 and the lower motorized roller conveyor 11 are located at the bottom of the crossbeam frame 4, and the clamping cylinder 1 is fixedly connected to the top of the crossbeam frame 4.

[0036] A set of straightening mechanisms 12 is provided on each of the front and rear sides of the central motorized roller conveyor 7. The straightening mechanism 12 includes a push cylinder, and a straightening plate is connected to the inner side of the push cylinder. A drive motor 13 is provided inside the central motorized roller conveyor 7. A drive shaft 14 is provided at the left end of the drive motor 13. A first bevel gear 15 is provided on the outer side of the drive shaft 14. A second bevel gear 16 meshes with the rear end of the first bevel gear 15. A rolling roller body 17 is connected to the rear end of the second bevel gear 16. The rolling roller body 17 is located at the top of the waste sand chute 8.

[0037] When using the engine block vibrating sander, first connect the equipment to the power supply and the grid. Then, move the workpiece to the designated position using the central motorized roller conveyor 7. Next, start the lifting cylinder 9, which will drive the central motorized roller conveyor 7 to rise and fall to the designated position. At this point, the vibrating head 3 and the return spring 5 will be located on the left and right sides of the workpiece.

[0038] Working principle: When using the engine block vibrating sander, first connect the equipment to the power grid for power supply. Then, the central motorized roller conveyor 7 moves the workpiece to the designated position. Then, start the lifting cylinder 9, which drives the central motorized roller conveyor 7 to rise and fall to the designated position. At this time, the vibrating head 3 and the return spring 5 will be located on the left and right sides of the workpiece. Then, the clamping cylinder 1 drives the high-frequency vibrator 2 to run, which drives the vibrating head 3 to vibrate and move, so that the vibrating head 3 vibrates the workpiece. At the same time, the return spring 5 will also support and reset the workpiece on the left side.

[0039] When the device is adjusting the front and rear position of the workpiece, the straightening plate can be moved by the push cylinder inside the straightening mechanism 12, so that the straightening plate pushes the workpiece to the center position of the central motorized roller conveyor 7. During the sand shaking process, the sand will fall into the waste sand chute 8. The user can collect the waste sand by placing a waste sand cart at the bottom of the waste sand chute 8.

[0040] When the central motorized roller conveyor 7 is running, the drive motor 13 drives the drive shaft 14 to rotate, which in turn drives the first bevel gear 15 to rotate. This causes the first bevel gear 15 to drive the second bevel gear 16 and the rolling roller body 17 to rotate, thus moving the workpiece to the designated position.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
