Description

Technical Field

[0001] This invention relates to the field of precision parts processing technology, and in particular to a sandblasting device for precision parts processing. Background Technology

[0002] In high-end manufacturing fields such as aerospace, automotive parts, medical devices, 3C electronics, and precision molds, precision parts, with their core advantages of high dimensional accuracy, excellent surface quality, and stable mechanical properties, have become the key support for achieving high performance and high reliability in various end products. The surface processing quality of these parts directly determines their assembly accuracy, corrosion resistance, fatigue life, and coating adhesion.

[0003] Sandblasting, as a core step in the surface treatment of precision parts, uses high-pressure airflow to propel abrasive onto the surface of the parts. It can achieve multiple functions such as oxide scale removal, burr removal, surface roughening, stress strengthening, and matte finishing. It can improve the micro-morphology of the part surface and enhance the surface hardness and wear resistance. It is an indispensable process for achieving refined and high-quality machining of precision parts and is widely used in the processing of various precision parts such as gears, shafts, 3D printed implants, and electronic housings.

[0004] However, existing sandblasting equipment has a relatively simple structure, making it inconvenient to fold and adjust, and unable to be used in confined spaces, thus affecting sandblasting efficiency. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of existing sandblasting equipment having a simple structure, being inconvenient to fold and adjust, and being unable to be used in confined spaces, and to propose a sandblasting equipment for precision parts processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A sandblasting device for precision parts processing includes a base and a support column. The support column is fixedly connected to the top of the base. The support column is provided with a sliding opening. A sliding rod is fixedly connected inside the sliding opening. A slider is slidably sleeved on the sliding rod. A support block is fixedly connected to one side of the support column.

[0008] A screw is rotatably inserted into the support block. A knob is fixedly connected to the bottom of the screw. A threaded sleeve is threaded onto the top of the screw. The top of the threaded sleeve is fixedly connected to the slider. One end of the slider is rotatably connected to a support plate via a rotating rod. One end of the rotating rod is fixedly connected to a handle.

[0009] The bottom of the support plate is provided with an installation groove, and a guide rod is fixedly connected in the installation groove. A fixing block is slidably sleeved on the guide rod. The fixing block is connected to the outer wall of the threaded sleeve through a connecting plate. The two ends of the connecting plate are rotatably connected to the fixing block and the threaded sleeve, respectively. A sandblasting mechanism is fixedly connected to one end of the guide rod.

[0010] In one possible implementation, a locking lever is slidably inserted into the knob, and a plurality of locking slots corresponding to the locking lever are arranged around the support block.

[0011] In one possible implementation, a retaining sleeve is fixedly fitted to one end of the lever near the support block, and a pull rod is fixedly connected to the other end of the lever away from the retaining sleeve. A first spring is fitted onto the lever, and the two ends of the first spring are fixedly connected to the retaining sleeve and the knob, respectively.

[0012] In one possible implementation, a limit block is fixedly connected to the top of the screw.

[0013] In one possible implementation, a second spring is sleeved on the guide rod, and the two ends of the second spring are fixedly connected to the fixing block and the inner wall of the mounting groove, respectively.

[0014] In one possible implementation, the slider has a through-hole corresponding to the slide bar, and a plurality of steel balls are slidably connected in the through-hole, with the edges of the steel balls contacting the slide bar.

[0015] In one possible implementation, a handrail is fixedly connected to one side of the top of the support column.

[0016] In one possible implementation, the bottom of the base is fixedly connected to a plurality of locking blocks, and the locking blocks are provided with locking ports.

[0017] In one possible implementation, a locking screw is threaded into the handle, and a plurality of locking grooves corresponding to the locking screw are arranged around the slider.

[0018] Beneficial effects:

[0019] 1. In this invention, rotating the knob drives the screw to rotate, which in turn drives the slider to slide through the threaded sleeve, thereby adjusting the height of the support plate. Then, rotating the handle drives the rotating rod to rotate, which can adjust the rotation of the support plate and fold or unfold it.

[0020] 2. In this invention, the folding and adjusting structures allow the sandblasting mechanism to be folded and adjusted according to actual usage needs, enabling it to be used in confined spaces and improving sandblasting efficiency.

[0021] 2. The locking lever in this invention facilitates the fixing of the knob, and the guide rod, fixing block and connecting plate prevent the support plate from shaking. At the same time, the second spring provides elastic support to the fixing block, and the limiting block prevents the screw from falling out of the threaded sleeve. Attached Figure Description
