Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic component processing, in particular to a sandblasting machine for cleaning the inside of a hydraulic component. Background Art

[0002] The working principle of the sandblasting machine is mainly to use compressed air to form a high-speed jet beam, driving the spray material (such as quartz sand, glass beads, corundum, iron sand, steel sand, etc.) to spray at high speed onto the surface of the workpiece. This spraying action will generate a strong mechanical force, and the surface stains, sediments, corrosion layers, etc. will be removed through the impact and cutting of the abrasive on the workpiece surface, so as to obtain a clean, smooth and good processed surface. The working principle of the sandblasting machine also includes the use of compressed air system, nozzle and abrasive. The compressed air system generates high-pressure air to accelerate the abrasive to high speed to form a high-speed jet flow. The nozzle is the core component of the sandblasting machine. By adjusting the size, angle and other parameters of the nozzle, the flow rate and speed of the abrasive are controlled to achieve the spraying and cleaning effect of the abrasive. The choice of abrasive depends on different processing requirements, such as steel shot, quartz sand, glass beads, etc. Different abrasive particle sizes and materials can achieve different cleaning effects.

[0003] After hydraulic work is completed, the hydraulic parts need to be polished and ground using a sandblasting machine. If the hydraulic parts are cylindrical or have holes on them, the spray or dust will accumulate inside the holes or adhere to the inner walls of the holes, requiring manual cleaning of the inside, which consumes a lot of time and labor.

[0026] A pushing assembly is installed between the mounting plate 10 and the mounting base 1 and the workpiece clamping assembly corresponding to the position, and the two pushing assemblies are symmetrically arranged to ensure that the movement trends of the two pushing assemblies are the same. The pushing assembly includes a pushing cylinder 9, one end of the pushing cylinder 9 is rotatably connected to a first support 13, and the first support 13 is slidably connected to the U-shaped clamping frame 3, and the mounting plate 10 and the mounting base 1 are fixedly connected to a second support, and the pushing cylinder 9 is rotatably connected to the first support 13 and the second support at the corresponding positions;

[0027] The workpiece clamping assembly includes a U-shaped clamping frame 3, a limiting groove 7 is provided on the side wall of the U-shaped clamping frame 3, and a first support 13 is slidably connected in the limiting groove 7, a rotating ball 8 is installed on the side wall of the U-shaped clamping frame 3, a connecting rod 2 is fixedly connected to the rotating ball 8, and the connecting rod 2 is fixedly connected to the mounting plate 10 or the mounting base 1 at a corresponding position, a spherical groove is provided on the side wall of the U-shaped clamping frame 3, and the rotating ball 8 is clamped in the spherical groove, and the depth of the spherical groove is greater than the radius of the rotating ball 8;

[0028] A locking plate 4 is slidably connected to the U-shaped clamping frame 3, and a plurality of sliding grooves 6 are symmetrically opened on the U-shaped clamping frame 3. A plurality of sliders are symmetrically fixedly connected to each locking plate 4, and each slider is slidably connected in the sliding groove 6 at a corresponding position.
