Description

Technical Field

[0001] The present invention relates to the technical field related to injection lines, and in particular to a portable angle adjustment mechanism for a cyclotron injection line. Background Art

[0002] There is an installation angle requirement between the accelerator deflection plate and the injection line magnetic pole. Currently, a hard connection method is adopted, and then the beam direction is fine-tuned by electronic control to eliminate the processing error of the equipment processing parts themselves. Now, due to the space limitation of the accelerator deflection plate, it is a single-arm support structure with installation errors. The injection line is also cast as a whole, and the magnetic pole concentricity position requirement cannot be as accurate as the theoretical calculation. Therefore, it is often found that even if the electronic control is set to the limit value, it is far from the expected result. During the debugging period, some improvement is achieved by rotating the fixed angle. However, due to the limitation of the fastening hole, the rotation angle can only be a fixed multiple value of 360 / the number of screw holes n, which is inconvenient to adjust. For production enterprises, how to improve efficiency is the most important thing. To address this problem, it is necessary to design a portable angle adjustment mechanism for the cyclotron injection line. Summary of the Invention

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0049] The present invention provides Figure 1-7The portable angle adjustment mechanism of a cyclotron injection line shown in the figure includes an injection line 1 and a cover plate 2. The bottom end of the injection line 1 is provided with a mounting adjustment mechanism, which includes a mounting plate 3, a rack 4, a fixing frame 5, an adjustment component 6 and a positioning component 7. The mounting plate 3 is fixedly connected with the injection line 1 through insertion. Waist holes connected to the cover plate 2 are equidistantly provided on the mounting plate 3. The plurality of waist holes are symmetrically arranged with the center of the injection line 1 as the center. When debugging and installing the injection line 1, the injection line 1 needs to be able to rotate without affecting the installation. Therefore, the mounting plate 3 is used for connecting with the accelerator cover plate 2. The connecting hole is changed to a waist hole for easy adjustment. An arc groove is provided on the outer wall of the mounting plate 3, and the rack 4 is fixedly connected to the inner wall of the arc groove. Because the magnetic poles of the injection line 1 are symmetrically distributed, only 90° adjustment is required. According to the angular installation requirements between the accelerator deflection plate and the magnetic poles of the injection line 1, first match them and then take an arc groove to place the arc-shaped rack 4 inside. The fixing frame 5 is arranged at the top of the cover plate 2, and the adjustment component 6 is arranged inside the fixing frame 5 for rotating the rack 4. The positioning component 7 is arranged inside the fixing frame 5 for multi-point positioning of the fixing frame 5 and the adjustment component 6.

[0050] Specifically, the adjustment component 6 includes a rotating shaft 61, a worm wheel 62, a first gear 63, a worm 64 and a handwheel 65. The rotating shaft 61 is rotatably arranged inside the fixed frame 5, and the worm wheel 62 is rotatably arranged inside the fixed frame 5 through the rotating shaft 61. The first gear 63 is fixedly connected to the rotating shaft 61, and the first gear 63 is meshed with the rack 4. The worm 64 is rotatably arranged inside the fixed frame 5, and the worm 64 is meshed with the worm wheel 62. In order to improve the angle adjustment accuracy of the injection line 1, the transmission ratio of the active wheel and the driven wheel should be as large as possible. Since the injection line 1 itself weighs several hundred kilograms, in order to make the adjustment more labor-saving, a hand-cranked worm wheel 62 and worm 64 structure is added to the rack 4 for ease of use. The worm wheel 64 can drive the worm wheel 62 to rotate, thereby driving the first gear 63 coaxial with the worm wheel 62 to rotate, so that the rack 4 can be driven to rotate by the first gear 63 to achieve adjustment of the injection line 1 at any angle. The handwheel 65 is fixedly connected to one end of the worm 64 for rotating the worm 64.

[0051] Furthermore, the outer wall of the handwheel 65 is provided with a rubber sleeve 8, and the outer wall of the rubber sleeve 8 is provided with an anti-slip texture. The provision of the anti-slip texture increases the friction between the operator's hand and the handwheel 65, so that the operator can operate the handwheel 65 more firmly and comfortably when holding the handle on the handwheel 65, avoiding hand slipping, and improving the accuracy and safety of the operation.

[0052] When the locking cam 72 is in the unlocking state, the locking cam 73 is locked and the locking cam 73 is locked. When the locking cam 75 is in the unlocked position, the locking cam 73 is in the unlocked position, and the locking cam 73 is in the unlocked position, so that the locking cam 73 is locked and the locking cam 73 is in the unlocked position.

[0053] Furthermore, the mounting assembly 77 includes: an extrusion plate 771, an extrusion rod 772, a clamping rod 773 and a second compression spring 774. A groove is provided on one side of the inner wall of the extrusion groove. The extrusion plate 771 is located inside the groove. One end of the extrusion rod 772 is fixedly connected to the extrusion plate 771. The other end of the extrusion rod 772 is slidably connected to the inner wall of the groove. The clamping rod 773 is fixedly connected to the other end of the extrusion rod 772. The second compression spring 774 is sleeved on the outside of the extrusion rod 772. One end of the second compression spring 774 is fixedly connected to the extrusion plate 771. The other end of the second compression spring 774 is fixedly connected to the inner wall of the groove The second compression spring 774 is always in a compressed state, thereby providing a stable elastic force to the extrusion plate 771, so that the extrusion plate 771 can be tightly attached to the eccentric wheel 72. When the long radius end of the eccentric wheel 72 is in contact with the extrusion plate 771, the extrusion rod 772 can squeeze out the clamping rod 773, thereby clamping and limiting the rack plate 775. When the short radius end of the eccentric wheel 72 is in contact with the extrusion plate 771, under the elastic force of the second compression spring 774, the extrusion rod 772 can drive the clamping rod 773 to disengage from the clamping groove, thereby pulling the rack plate 775 to achieve installation and disassembly of the fixing frame 5.

[0054] Furthermore, the mounting assembly 77 further includes: a rack plate 775, a second gear 776 and an L-shaped rod 777. The interior of the fixing frame 5 is symmetrically staggered with sliding grooves, the rack plate 775 is slidably inserted and connected with the inner cavity of the sliding groove, the outer wall of one of the rack plates 775 is provided with a clamping groove, the clamping rod 773 is slidably inserted and connected with the inner cavity of the clamping groove, the interior of the fixing frame 5 is provided with a through groove communicating with the sliding groove, the second gear 776 is rotatably set inside the through groove, and the second gear 776 is meshed with the rack plate 775. The L-shaped rod 777 is fixedly connected to the bottom end of the rack plate 775, and the top of the cover plate 2 is symmetrically staggered with installation grooves for the L-shaped rod 777 to penetrate. The number of L-shaped rods 777 and installation grooves is at least two, and corresponds to each other. By pulling or pushing one of the rack plates 775, the other rack plate 775 can be driven to move through the second gear 776, so that the L-shaped rod 777 can be moved, disengaged from the installation groove or clamped with the installation groove, thereby realizing the disassembly and installation of the fixing frame 5, which is convenient for use.

[0055] Furthermore, a limiting groove is provided on the opposite side of the inner wall of the sliding groove, and the inner cavity of the limiting groove is slidably inserted and connected with a limiting block 9, and the limiting block 9 is fixedly connected to the rack plate 775. The limiting block 9 plays a limiting role on the rack plate 775, so that the rack plate 775 can only move horizontally along the limiting groove when displacing.

[0056] The working principle of the present invention is as follows: when debugging and installing the injection line 1, the injection line 1 and the mounting plate 3 are first rotated and set above the cover plate 2. At this time, after the L-shaped rod 777 under the fixing frame 5 is inserted into the interior of the mounting groove, one of the rack plates 775 is pushed, thereby driving the other rack plate 775 to move through the second gear 776, so that multiple L-shaped rods 777 are respectively inserted into the interior of multiple mounting grooves. At this time, the long radius end of the eccentric wheel 72 and the extrusion plate 771 are used to make the extrusion rod 772 squeeze the clamping rod 773 Out, thereby engaging and limiting the engaging groove opened by the rack plate 775, so that the fixing frame 5 is installed on the cover plate 2. After installation, pull the pull plate 73 as needed to make the positioning rod 75 disengage from the positioning hole, thereby rotating the worm 64 through the handwheel 65, and the worm 64 drives the worm wheel 62 to rotate, thereby driving the first gear 63 coaxial with the worm wheel 62 to rotate, thereby driving the rack 4 to rotate through the first gear 63, and adjusting the angle of the injection line 1 as needed, so that the debugging is completed, and the injection line 1 can be installed by bolts.
