Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a full-automatic drum shot blasting machine. Background Art

[0002] A shot blasting machine refers to a casting equipment that uses high-speed projectiles thrown by a shot blasting device to clean or strengthen the surface of castings. For the existing drum shot blasting machine, when shot blasting and cleaning small precision parts, such as workpieces like bolts, nuts, and gaskets, the cleaning effect on the surface of the workpieces is not good. The reason is that the shot blasting device is arranged on the door cover of the drum, and its shot blasting angle is limited. When the drum rotates, the workpieces are not easy to turn over. Once there are too many workpieces, the workpieces at the bottom layer are not easy to turn up, directly affecting the quality of shot blasting. In addition, because the shot blasting device is arranged on the door cover, its own weight is large, and its opening and closing are rather troublesome. The traditional method is to rely on a single oil cylinder to lift the door cover. However, for the door cover with the shot blasting device, its center of gravity is not easy to control. After a long time, the door cover will be severely deformed due to uneven stress, making the door cover unable to close on the box body, resulting in the outward splashing of projectiles. Content of the Utility Model

[0003] In order to make up for the deficiencies of the prior art, the utility model provides a full-automatic drum shot blasting machine, which has a reasonable structural design and is convenient to operate. It can arbitrarily adjust the inclination angle of the drum according to needs during the shot blasting process, so as to easily turn up the workpieces at the bottom layer, improve the quality of shot blasting, and is especially suitable for the shot blasting and cleaning of small precision parts. Moreover, it can easily realize the opening and closing of the door cover, make the door cover evenly stressed, effectively prevent the deformation of the door cover, improve the airtightness of the door cover, avoid the outward splashing of projectiles, improve the service life of the shot blasting machine, and solve the problems existing in the prior art.

On the two support platforms 2, box body bearing seats 3 are symmetrically arranged. A box body rotating shaft 4 is respectively movably arranged on the two box body bearing seats 3. Between the two cross beams 101 of the chassis 1, there is a box body 5. The box body 5 is movably hinged on the box body rotating shaft 4 between the two box body bearing seats 3 through box body hinge seats 6 symmetrically arranged on the front and rear sides of the bottom of its right side wall. On the upper part of the left side wall of the box body 5, there is an upper hinge seat 7. At the bottom of the chassis 1 corresponding to the position of the upper hinge seat 7, there is a support beam 102 arranged parallel to the cross beam 101. At the left end of the support beam 102, there is a lower hinge seat 8. The upper hinge seat 7 and the lower hinge seat 8 are connected by a tilting oil cylinder 9. In the middle of the right side wall of the box body 5, there is a feed inlet 10. A door cover 11 is movably abutted against one side of the feed inlet 10 through a closing mechanism.

[0021] Optionally, the closing mechanism includes upper bearing seats 12 symmetrically arranged on the front and rear sides of the upper part of the right side wall of the door cover 11. An upper rotating shaft 13 is respectively movably clamped in the two upper bearing seats 12. The front and rear ends of the upper rotating shaft 13 respectively penetrate through the corresponding upper bearing seats 12 on one side and are connected to a driving member. On the front and rear sides of the lower part of the right side wall of the door cover 11, lower bearing seats 14 are symmetrically arranged respectively. A lower rotating shaft 15 is respectively movably clamped in the two lower bearing seats 14. The front and rear ends of the lower rotating shaft 15 respectively penetrate through the corresponding lower bearing seats 14 on one side and are connected to a linkage member.

[0022] Optionally, the driving member includes upper rotating seats 16 provided on the upper portions of the front and rear side walls of the box body 5. The middle portion of an L-shaped lever 17 is movably hinged to the upper rotating seat 16. The long section of the L-shaped lever 17 is movably sleeved on the upper rotating shaft 13 on the corresponding side. A connecting column 18 is provided at the end of its short section. A support frame 19 is provided on the box body 5 on the left side of the upper rotating seat 16. A cylinder 20 is movably clamped in the support frame 19 through a clamping shaft 21 provided on its cylinder barrel. The end of the piston rod of the cylinder 20 is movably clamped to the connecting column 18 on this side.

[0023] Optionally, the linkage member includes lower rotating seats 22 provided in the middle portions of the front and rear side walls of the box body 5. The left end of a linkage rod 23 is movably hinged to the lower rotating seat 22, and the right end of the linkage rod 23 is movably sleeved on the lower rotating shaft 15 on the corresponding side.

[0024] Optionally, the position height of the upper rotating seat 16 on the box body 5 is higher than the position height of the upper bearing seat 12 on the box body 5.

[0025] Optionally, it further includes ventilation mechanisms symmetrically arranged on the front and rear sides of the box body 5. The ventilation mechanisms include ventilation pipes 24 communicatively arranged in the middle portions of the front and rear side walls of the box body 5. An exhaust pipe 25 is communicatively provided at the outer end of the ventilation pipe 24. The outer end of the exhaust pipe 25 is clamped to the box body rotating shaft 4 on the corresponding side. Ventilation holes 26 are provided on the outer side wall of the exhaust pipe 25 near the box body rotating shaft 4. An asbestos mesh block is provided in the exhaust pipe 25. During the working process of the shot blasting machine, a large amount of heat is generated due to the high-speed impact of the shot on the workpiece. This part of the heat enters the box body 5 through the drum and is discharged outward through the ventilation pipe 24, the exhaust pipe 25, and the ventilation holes 26 in sequence. The asbestos mesh block can absorb the heat, avoid scalding the workers by the discharged hot air, and also avoid the heat accumulating in the box body 5 and being unable to dissipate, further improving the quality of the workpiece.

[0026] When the shot blasting machine is working, the angle of the box body 5 can be adjusted according to the size of the workpiece. Moreover, during the shot blasting process, the angle can be reciprocally adjusted, thereby adjusting the inclination angle of the drum in the box body 5, so as to easily turn the workpieces at the bottom upwards, improve the shot blasting quality, and is especially suitable for the shot blasting and cleaning of small precision parts. Start the two tilting cylinders 9. Through the outward extension of the piston rods of the tilting cylinders 9, the box body 5 is pushed upwards through the upper hinge seat 7, and the box body 1 rotates upwards along the two box body bearing seats 3 with the axis line of the box body rotating shaft 4 as the center of the circle, so as to achieve the purpose of adjusting the inclination angle of the box body 5. Also, by adjusting the inclination angle of the box body 5, the purpose of discharging materials can be more easily achieved, making it easier to take out the processed workpieces. The opening and closing of the door cover 11 rely on the driving parts on both sides. When it needs to be opened, start the cylinder 20 to make its piston rod extend outwards, and then push the short section of the L-shaped lever 17 through the connecting column 18, making it rotate along the upper rotating seat 16, and then making the long section of the L-shaped lever 17 rotate, finally separating the upper part of the door cover 11 from the feed inlet 10. As the door cover 11 is lifted upwards, the lower part of the door cover 11 is turned upwards along the lower rotating seat 22 through the linkage rod 23, thereby increasing the turning angle of the door cover 11 and completely separating it from the feed inlet 10. It has a reasonable structural design and is convenient to operate. It is especially suitable for the shot blasting and cleaning of small precision parts, and can easily open and close the door cover 11, making the door cover 11 evenly stressed, effectively preventing the deformation of the door cover, improving the airtightness of the door cover 11, avoiding the outward splashing of shot, increasing the service life of the shot blasting machine, and solving the problems existing in the prior art.
