Technical Field

[0002] Sandblasting is a process of cleaning and roughening the surface of a substrate by using the impact of a high-speed sand stream. It is generally done by a sandblasting machine, which is powered by compressed air. The working pressure established by the compressed air in the pressure tank forces the abrasive through the sand outlet valve, into the sand delivery pipe, and out through the nozzle to be sprayed onto the surface to be processed to achieve the desired purpose. With the development of industrial manufacturing, sandblasting equipment is needed to sandblast the surface of mechanical workpieces before precision machining.
[0003] A precision machining sandblasting device disclosed in Chinese Patent CN220007393U includes a machining platform, a sandblasting box, and a sand collection assembly.

A screw is rotatably connected inside the rectangular groove, and a pressure plate is threaded onto the outside of the screw. A lead screw is rotatably connected between the two vertical plates. A servo motor is fixedly connected to the outside of one of the vertical plates. The output end of the servo motor is fixedly connected to the lead screw via a coupling. A slider is threaded onto the outside of the lead screw, and a sandblasting head is installed at the bottom of the slider.
[0004] The existing sandblasting equipment described above uses a hydraulic cylinder and a pressure plate to clamp and fix the workpiece, and a servo motor to drive the sandblasting head to sandblast the workpiece. However, after the upper surface of the workpiece is sandblasted, the equipment needs to remove the workpiece, turn it over, and then sandblast it again, which results in low work efficiency.

[0014] Beneficial effects

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0025] Please see Figure 1-4 This utility model provides a technical solution: a precision machining sandblasting equipment, including an equipment box 1, a baffle plate 11 fixedly installed on the inner wall of the equipment box 1, and protective boxes 8 fixedly installed on both sides of the inner wall of the equipment box 1 above the baffle plate 11.
[0026] The protective box 8 is equipped with an electric telescopic rod 17 that can be rotated inside. The equipment box 1 is fixedly installed on both sides of the first motor 3, and the output shaft of the first motor 3 is fixedly connected to the corresponding electric telescopic rod 17.
[0027] The telescopic ends of the two electric telescopic rods 17 are set opposite each other.
[0028] Clamping components are fixedly installed on the telescopic ends of both electric telescopic rods 17. Specifically, the clamping components include an L-shaped clamping plate 7, a pressure plate 9, and an adjusting screw 19. The L-shaped clamping plate 7 is fixedly installed on the telescopic end of the electric telescopic rod 17. A sliding groove is provided on the L-shaped clamping plate 7. The pressure plate 9 is slidably installed in the sliding groove. The adjusting screw 19 is rotatably installed in the sliding groove and is threadedly connected to the pressure plate 9.
[0029] On both sides of the inner wall of the equipment housing 1, striking plates 10 are slidably installed between the protective box 8 and the barrier plate 11. Specifically, both sides of the inner wall of the equipment housing 1 have inner grooves 21, and sliders 20 are slidably installed inside the inner grooves 21. Springs 22 are fixedly connected inside the inner grooves 21, and the other end of the springs 22 is fixedly connected to the sliders 20. The sliders 20 are fixedly connected to the striking plates 10.
[0030] A linkage assembly is provided between the striking plate 10 and the electric telescopic rod 17. Specifically, the linkage assembly includes a double-headed rack 14, a rack 16, and a gear 18. The gear 18 is fixedly installed on the outside of the electric telescopic rod 17. The inner wall of the equipment housing 1 is provided with a sliding groove 15 corresponding to the inside of the protective box 8. The double-headed rack 14 is slidably installed inside the sliding groove 15, and the gear 18 meshes with the upper teeth of the double-headed rack 14. The rack 16 is fixedly connected to the upper end face of the striking plate 10. The top end of the rack 16 slides through into the inside of the protective box 8, and the rack 16 slides with the lower teeth of the double-headed rack 14.
[0031] Sand hoppers 12 are fixedly installed on both sides of the inner wall of the equipment housing 1, corresponding to the lower part of the baffle plate 11. A collection box 13 is movably placed at the bottom of the equipment housing 1. A door 2 is provided on the side wall of the equipment housing 1 at the position corresponding to the collection box 13. The collection box 13 can be taken out by opening the door 2.
[0032] A mounting block 6 is movable at the top of the internal structure of the equipment housing 1. A sandblasting head 5 is fixedly mounted at the bottom of the mounting block 6. A second motor 4 is fixedly mounted on the side wall of the equipment housing 1. A screw is fixedly connected to the output shaft of the second motor 4. The screw is rotatably mounted inside the equipment housing 1 and is threadedly connected to the mounting block 6. The sandblasting head 5 is connected to an external sandbox. When the second motor 4 is started, its rotation drives the screw to rotate, which in turn moves the mounting block 6, thereby causing the sandblasting head 5 to perform sandblasting on the workpiece.
[0033] Working principle:
[0034] In use, rotating the adjusting screw 19 clamps the workpiece to be processed between the L-shaped clamping plate 7 and the pressure plate 9.
[0035] The second motor 4 is started, and its rotation drives the screw to rotate, which in turn moves the mounting block 6, thereby driving the sandblasting head 5 to sandblast the workpiece to be processed. After one side of the workpiece to be processed is sandblasted, the first motor 3 is started. The output end of the first motor 3 drives the electric telescopic rod 17 to rotate, and the electric telescopic rod 17 drives the clamping part to rotate, thereby causing the workpiece to be processed to be rotated 180 degrees, which facilitates sandblasting of the other side of the workpiece and improves the ease of use of the device.
[0036] When the electric telescopic rod 17 rotates, the gear 18 fixed on it drives the double-headed rack 14 to slide in the slide groove 15. When the double-headed rack 14 slides, the lower tooth engages with the rack 16, so that when the rack 16 contacts the end of the lower tooth, the slider 20 slides downward in the inner groove 21, thereby compressing the spring 22. The striking plate 10 contacts the barrier plate 11. When the rack 16 disengages from the end of the lower tooth, the slider 20 slides upward in the inner groove 21, thereby restoring the spring 22 to its original deformation. This achieves the effect of the striking plate 10 striking the barrier plate 11, so that the sand and gravel that have not fallen from the gap on the barrier plate 11 can fall from the gap due to the vibration of the barrier plate 11, preventing the accumulation of sand and gravel on the barrier plate 11 and avoiding later cleaning.
[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
