Specific implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1 - Figure 5 , the present invention provides a technical solution: a shot blasting machine frame welding device, including a fixed beam 1, a push screw 2 is rotatably connected inside the fixed beam 1, a threaded sleeve 3 is rotatably connected to the outside of the push screw 2 near one side of the fixed beam 1, a plastic soft sheet 6 is fixedly connected to the outside of the threaded sleeve 3, there are multiple groups of plastic soft sheets 6 arranged in a circumferential array outside the threaded sleeve 3, a positioning block 7 is abutted against the outside of the plastic soft sheet 6, a rotating rod 4 is arranged outside the positioning block 7, a positioning groove 5 is opened inside the rotating rod 4, the side of the positioning block 7 away from the plastic soft sheet 6 is fixedly connected inside the positioning groove 5, a friction groove 8 is opened on the outside of the rotating rod 4 away from the fixed beam 1, a sliding block 10 is fixedly connected to the outside of the rotating rod 4 away from the friction groove 8, a sliding groove 9 is opened inside the fixed beam 1, and the sliding block 10 is slidably connected inside the sliding groove 9.

[0024] During operation, when fixing the frame, rotate the threaded sleeve 3 to drive the push screw 2 to rotate. The threaded sleeve 3 rotates outside the positioning block 7 by relying on the plastic soft sheet 6, so as to squeeze and fix the push screw 2. Even if there is shaking, the threaded sleeve 3 will not reverse due to vibration. Even when there is a reverse force, the positioning block 7 can also limit the rotation direction of the plastic soft sheet 6. When unlocking is required, pull the rotating rod 4 by relying on the friction groove 8 to separate the positioning block 7 from the outside of the plastic soft sheet 6. At this time, the threaded sleeve 3 can be rotated to drive the push screw 2 to contract, so as to achieve the effect of locking when fixed to ensure stability and being able to rotate in any direction after unlocking.

[0025] One end of the push screw 2 away from the rotating rod 4 is fixedly connected with an extrusion block 11. An engaging groove 12 is formed on one side of the extrusion block 11 away from the push screw 2. The top of the fixed beam 1 is fitted with a support rod 14. The top of the support rod 14 is fixedly connected with a clamping block 15. A positioning port 16 is formed on one side of the clamping block 15 close to the extrusion block 11. There are two groups of fixed beams 1 arranged symmetrically. A connecting beam 13 is fixedly connected at a position close to the center on the opposite sides of the fixed beam 1.

[0026] During operation, when the push screw 2 is extruded, the push screw 2 will push the extrusion block 11, so that the extrusion block 11 is fitted outside the frame through the engaging groove 12 to achieve preliminary fixation. After the preliminary fixation is completed, the clamping block 15 is fixed above the fixed beam 1 by relying on the support rod 14. At this time, it is fitted on the surface of the device through the positioning port 16, so as to fixedly install the device. In this way, double fixation is achieved, so as to achieve the effect of installation and welding.

[0027] During operation or use, when fixing the frame, rotate the threaded sleeve 3 to drive the push screw 2 to rotate. The threaded sleeve 3 rotates outside the positioning block 7 by relying on the plastic soft sheet 6, so that the push screw 2 is extruded and fixed. Even if there is shaking, the threaded sleeve 3 will not reverse due to vibration. Even when there is a reverse force, the positioning block 7 can also limit the rotation direction of the plastic soft sheet 6. When unlocking is required, pull the rotating rod 4 by relying on the friction groove 8 to separate the positioning block 7 from the outside of the plastic soft sheet 6. At this time, the threaded sleeve 3 can be rotated to drive the push screw 2 to contract, so as to achieve the effect of locking when fixed to ensure stability and being able to rotate in any direction after unlocking. When the push screw 2 is extruded, the push screw 2 will push the extrusion block 11, so that the extrusion block 11 is fitted outside the frame through the engaging groove 12 to achieve preliminary fixation. After the preliminary fixation is completed, the clamping block 15 is fixed above the fixed beam 1 by relying on the support rod 14. At this time, it is fitted on the surface of the device through the positioning port 16, so as to fixedly install the device. In this way, double fixation is achieved, so as to achieve the effect of installation and welding.
