Description

Technical Field

[0001] This utility model relates to the field of sandblasting machines, and in particular to a sandblasting machine that is easy to adjust the sandblasting angle. Background Technology

[0002] With societal progress and the increasing sophistication of industrial production, sandblasting machines play a crucial role in numerous fields. By spraying sand particles at high speed, sandblasting machines can effectively remove dirt, rust, oxide layers, and other impurities from the surface of workpieces. At the same time, they roughen the workpiece surface, enhance the adhesion of coatings or platings, and improve the surface quality of workpieces. They are widely used in industries such as machinery manufacturing, automobile repair, shipbuilding, and building decoration.

[0003] However, existing sandblasting machines lack angle adjustment functions, forcing operators to wear gloves and hold the workpiece directly during sandblasting. While gloves provide some protection, prolonged contact with the strong impact of sandblasting can easily lead to hand fatigue, making it difficult to hold the workpiece stably for extended periods. This affects the accuracy and uniformity of sandblasting, reduces the surface treatment quality of the workpiece, and makes manual hand operation inefficient, failing to meet the demands of large-scale, high-efficiency production. Utility Model Content

[0004] In view of this, the present invention provides a sandblasting machine that is easy to adjust the sandblasting angle. The main technical problem to be solved is: to solve the problem that the existing sandblasting machines do not have an angle adjustment function, which leads to safety hazards, reduced processing quality and efficiency due to manual hand-held sandblasting of workpieces.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sandblasting machine that facilitates adjustment of the sandblasting angle, comprising a housing, a fixing component installed inside the housing, an adjusting component installed inside the housing, a sandblaster installed inside the adjusting component, and the sandblaster located on top of the fixing component;

[0006] The adjustment assembly includes a fixed ring, a support cylinder, a drive screw, a ball head, and a movable seat. The fixed ring is located inside the outer shell, and the sandblaster is fixedly installed on the inner wall of the fixed ring. There are three support cylinders, which are fixedly installed on the top of the inner wall of the outer shell. The drive screw is slidably installed inside the support cylinder. The ball head is fixedly connected to the bottom of the drive screw and is located at the bottom of the support cylinder. The movable seat is fixedly connected to the outer wall of the fixed ring, and there are three movable seats arranged in a ring. The ball head is movably installed inside the movable seat on the same side.

[0007] By adopting the above technical solution, the drive screw is rotated, which drives the ball head to move within the movable seat, thereby pushing the fixed ring and the sandblasting device within the fixed ring to adjust the angle.

[0008] As a further description of the above technical solution: the adjustment component also includes a rotating sleeve, a limiting block and a limiting groove. The rotating sleeve is movably installed at the bottom of the support cylinder. The inner wall of the rotating sleeve has a screw hole corresponding to the drive screw. The limiting block is fixedly connected to the top of the drive screw. The limiting groove is opened on the inner wall of the support cylinder and the limiting block is located inside the limiting groove.

[0009] By adopting the above technical solution, the rotating sleeve is rotated and threaded with the drive screw. Under the restriction of the limit block and the limit groove, the drive screw can only move up and down, thereby precisely controlling the lifting and lowering of the ball head and achieving more precise sandblasting angle adjustment.

[0010] As a further description of the above technical solution: the fixing assembly includes a support base, mounting slots, a bidirectional lead screw, clamping blocks, ear plates, movable seats, and slide rods. The support base is fixedly connected to the bottom of the inner wall of the housing. Three mounting slots are opened on the top of the support base. The bidirectional lead screw is movably installed inside the middle mounting slot. Two clamping blocks are fixedly connected to the top of the support base. Three ear plates are fixedly connected to the bottom of the clamping blocks. Two slide rods are fixedly installed inside the mounting slots on both sides.

[0011] By adopting the above technical solution, the bidirectional lead screw, slide bar and ear plate and other components cooperate with each other to stably clamp the workpiece.

[0012] As a further description of the above technical solution: the ear plate near the bidirectional lead screw has a screw hole corresponding to the bidirectional lead screw, and the ear plate near the slide bar has a sliding hole.

[0013] By adopting the above technical solution, when the bidirectional lead screw is rotated, the ear plate threadedly connected to the bidirectional lead screw moves the clamping block under the guidance of the slide rod, thereby realizing the clamping or releasing operation of the workpiece.

[0014] As a further description of the above technical solution: a turntable is fixedly connected to the outer wall of the bidirectional lead screw, and the turntable is located at the front end of the outer wall of the support base.

[0015] By adopting the above technical solution, the turntable can easily rotate the bidirectional lead screw.

[0016] As a further description of the above technical solution: a sealing door is movably installed on the outer wall of the outer shell, glass is embedded inside the sealing door, and a handle is fixedly connected to the outer wall of the sealing door.

[0017] By adopting the above technical solutions, the sealed door can prevent sand particles from splashing to the outside during the sandblasting process, the glass allows operators to easily observe the sandblasting situation inside, and the handle makes it easy to open and close the sealed door.

[0018] As a further description of the above technical solution: operating holes are provided on both sides of the outer wall of the outer shell, and support feet are fixedly connected to the bottom of the outer shell, and there are four support feet distributed in a rectangular shape.

[0019] By adopting the above technical solution, the operating hole allows operators to perform auxiliary operations on the internal workpieces without opening the sealed door, and the support feet provide stable support for the sandblasting machine, ensuring smooth operation of the equipment.

[0020] By employing the above technical solution, the sandblasting machine of this utility model, which facilitates the adjustment of the sandblasting angle, has at least the following beneficial effects:

[0021] 1. Compared with the existing technology, this sandblasting machine, which is easy to adjust the sandblasting angle, has a fixed component. When in use, the turntable is rotated, which drives the bidirectional lead screw to rotate. The bidirectional lead screw interacts with the screw hole on the ear plate on the side closest to it, so that the ear plate drives the clamping block to move under the guidance of the slide rod, thereby firmly clamping the workpiece. This avoids manual sandblasting of the workpiece by hand, ensuring the safety of the operator. Moreover, the workpiece is fixed more stably, which can effectively improve the sandblasting quality and processing accuracy.

[0022] 2. Compared with the existing technology, this sandblasting machine with easy-to-adjust sandblasting angle has an adjustment component. When in use, rotating the rotating sleeve drives the drive screw to move up and down. The ball head at the bottom of the drive screw moves in the movable seat, thereby pushing the fixed ring and sandblaster to change the angle. It can flexibly adjust the sandblasting angle according to the shape of the workpiece and the sandblasting requirements, improve the sandblasting effect, and improve work efficiency to meet the needs of different production scenarios.

[0030] Reference Figure 1-5 This utility model provides a sandblasting machine with an easily adjustable sandblasting angle: It includes a housing 1, inside which a fixing component 2 is installed to stably fix the workpiece to be sandblasted, ensuring that the workpiece position remains unchanged during sandblasting. Inside the housing 1, an adjusting component 3 is installed, which can flexibly adjust the angle of the sandblaster 4, allowing the sandblasting machine to adapt to sandblasting operations on workpieces of different shapes and requirements. The sandblaster 4 is installed inside the adjusting component 3, located on top of the fixing component 2. The adjusting component 3 includes a fixing ring 301, a support cylinder 302, a drive screw 303, a ball head 305, and a movable seat 306. The fixing ring 301 is located inside the housing 1, and the sandblaster 4 is fixedly installed on the inner wall of the fixing ring 301. The fixing ring 301 is used to fix the sandblaster 4. There are three support cylinders 302, which are fixedly installed on the top of the inner wall of the housing 1. The drive screw 303 is provided with a track for installation and sliding to ensure stable operation. The drive screw 303 is slidably installed inside the support cylinder 302. The drive screw 303 moves up and down, driving the ball head 305 to move, thereby adjusting the angle of the fixed ring 301 and the sandblaster 4. The ball head 305 is fixedly connected to the bottom of the drive screw 303 and is located at the bottom of the support cylinder 302. The ball head 305 cooperates with the movable seat 306 to convert the linear motion of the drive screw 303 into a push on the fixed ring 301, thereby achieving angle adjustment. The movable seat 306 is fixedly connected to the outer wall of the fixed ring 301. There are three movable seats 306 arranged in a ring. The ball head 305 is movably installed inside the movable seat 306 on the same side. The movable seat 306 connects the fixed ring 301 and the ball head 305. Under the action of the ball head 305, the fixed ring 301 is pushed to change the angle.

[0031] The adjustment assembly 3 also includes a rotating sleeve 304, a limiting block 307, and a limiting groove 308. The rotating sleeve 304 is movably installed at the bottom of the support cylinder 302. The inner wall of the rotating sleeve 304 has a threaded hole corresponding to the drive screw 303. The rotating sleeve 304 converts the rotational motion into the linear motion of the drive screw 303 through the threaded engagement with the drive screw 303, thereby achieving precise adjustment of the angle of the sandblaster 4. The limiting block 307 is fixedly connected to the top of the drive screw 303. The limiting block 307 cooperates with the limiting groove 308 to restrict the movement of the drive screw 303, so that it can only move up and down within the support cylinder 302, ensuring the stability of the adjustment process. The limiting groove 308 is opened on the inner wall of the support cylinder 302, and the limiting block 307 is located inside the limiting groove 308.

[0032] The fixing assembly 2 includes a support base 201, mounting slots 202, a bidirectional lead screw 203, a clamping block 204, an ear plate 205, and a movable seat 306. The movable seat 306 in this assembly has the same name as the movable seat 306 in the adjusting assembly 3, but its function is different. In the fixing assembly 2, it assists the ear plate 205 and other components in fixing the workpiece, and includes a slide rod 206. The slide rod 206 guides the movement of the ear plate 205, ensuring that the ear plate 205 drives the clamping block 204 to move smoothly, improving the workpiece fixing accuracy. The support base 201 is fixedly connected to the bottom of the inner wall of the outer casing 1. Three mounting slots 202 are formed on the top of the support base 201. The bidirectional lead screw 203 is movably mounted... Inside the middle mounting slot 202, the bidirectional lead screw 203 rotates to move the clamping blocks 204 in opposite directions, thereby clamping or releasing the workpiece. Two clamping blocks 204 are fixedly connected to the top of the support base 201. The clamping blocks 204 are in direct contact with the workpiece and are clamped and fixed by movement to ensure the stability of the workpiece during sandblasting. Three ear plates 205 are fixedly connected to the bottom of the clamping blocks 204. Two slide rods 206 are fixedly installed inside the mounting slots 202 on both sides. The ear plates 205 connect the bidirectional lead screw 203, the slide rods 206 and the clamping blocks 204, converting the rotation of the bidirectional lead screw 203 into the linear motion of the clamping blocks 204.

[0033] The ear plate 205 near the bidirectional lead screw 203 has a screw hole corresponding to the bidirectional lead screw 203, and the ear plate 205 near the slide bar 206 has a sliding hole.

[0034] A turntable 207 is fixedly connected to the outer wall of the bidirectional lead screw 203. The turntable 207 provides a force application point for the operator, making it convenient to rotate the bidirectional lead screw 203 and improving the ease of operation. The turntable 207 is located at the front end of the outer wall of the support base 201.

[0035] A sealing door 5 is movably installed on the outer wall of the outer casing 1. The sealing door 5 can effectively prevent sand particles from splashing outward during sandblasting operations, protecting the safety of operators and the surrounding environment. A glass 501 is embedded inside the sealing door 5, which allows operators to observe the sandblasting operation inside the sandblasting machine without opening the sealing door 5 and make timely adjustments to the operation. A handle 502 is fixedly connected to the outer wall of the sealing door 5, which makes it easy for operators to open and close the sealing door 5, making the operation simple and convenient.

[0036] Operating holes 6 are provided on both sides of the outer wall of the outer casing 1. The operating holes 6 allow the operator to reach into the sandblasting machine to adjust the position of the workpiece when the sealing door 5 is closed. Support feet 7 are fixedly connected to the bottom of the outer casing 1. The support feet 7 provide stable support for the sandblasting machine, ensuring that the equipment will not shake or shift during operation, and ensuring the accuracy and stability of the sandblasting operation. There are four support feet 7 arranged in a rectangular shape.

[0037] Working principle: First, the workpiece to be sandblasted is placed between three clamping blocks 204. The operator rotates the turntable 207, which drives the double-acting lead screw 203 to rotate. Since the ear plate 205 on the side near the double-acting lead screw 203 has a screw hole and is threaded to the double-acting lead screw 203, and the ear plate 205 on the side near the slide rod 206 has a sliding hole and moves under the guidance of the slide rod 206, the three ear plates 205 drive the clamping blocks 204 to move towards each other, firmly clamping the workpiece and ensuring that the workpiece will not shake during the sandblasting process.

[0038] Depending on the shape of the workpiece and the sandblasting requirements, the operator rotates one of the rotating sleeves 304. The inner wall of the rotating sleeve 304 is engaged with the drive screw 303 through a screw hole. When the rotating sleeve 304 rotates, the drive screw 303 can only move up and down within the support cylinder 302 under the restriction of the limit block 307 and the limit groove 308. The ball head 305 at the bottom of the drive screw 303 moves up and down accordingly. The ball head 305 moves within the movable seat 306. Since the movable seat 306 is fixed to the outer wall of the fixed ring 301, it pushes the fixed ring 301 and the sandblaster 4 inside the fixed ring 301 to change the angle. By adjusting the three positions, the angle of the sandblaster 4 can be adjusted flexibly and precisely to adapt to different workpiece sandblasting requirements.

[0039] If the position of the workpiece needs to be finely adjusted during the operation, it can be done by reaching in through the operation hole 6.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
