Abstract
Description
Technical Field
[0001] This utility model relates to the field of lead room technology, and in particular to a lead room radiation source protective cover and its processing equipment. Background Technology
[0002] A lead room is a radiation protection device constructed from high-density lead materials such as lead plates and lead bricks. Under current technology, it is widely used in medical imaging (such as CT rooms and DR rooms), radiotherapy, nuclear industry testing, and scientific research. Its function is to shield X-rays, gamma rays, and neutron rays, which can greatly protect the safety of personnel and the environment.
[0003] Traditional X-ray inspection radiation protection methods involve shielding the lead room itself. Lead rooms are large and costly. Meanwhile, protecting the X-ray tube is crucial. Reducing scattered radiation at the source significantly decreases the radiation level in the lead room, achieving the desired effect while reducing costs. The X-ray tube shield is fixed with bolts, and the bolt holes are often machined in stages. This involves adjusting the shield position after machining one hole before machining the next, resulting in low processing efficiency. Utility Model Content

[0005] To achieve the above objectives, this utility model provides a processing equipment for lead room radiation source protective covers, including a machine base, with an integral frame on both sides of the machine base, and also includes auxiliary mechanisms; The auxiliary mechanism includes a core block, a limiting plate, an abutment block, a moving frame, an electric spindle, a connecting frame, a first servo cylinder, a second servo cylinder, a clamping device, and a locking device. The core block is disposed on the upper side of the machine platform. The limiting plate is detachably installed on the rear side of the machine platform. The abutment blocks are symmetrically installed on both sides of the machine platform and symmetrically arranged on both sides of the limiting plate. The moving frame is disposed on both sides of the core block. The electric spindle is mounted on the moving frame, and a cutting tool is mounted on the electric spindle. The connecting frame is disposed on the side of the moving frame close to the machine frame. The first servo cylinder is mounted on the connecting frame, and its output end is connected to the moving frame. The second servo cylinder is mounted on the machine frame, and its output end is connected to the connecting frame. The clamping device is disposed on the top of the core block, and the locking device is disposed on the front side of the core block.
[0006] The pressing device includes a top plate and a side plate. The top plate is slidably connected to the limiting part on the rear side of the machine base and abuts against the top of the core block. The side plate is integrally formed with the top plate and abuts against the front side of the core block.
[0007] The locking device includes a mounting bracket and a mating assembly. The mounting bracket is detachably connected to the machine base and is located on the front side of the machine base, and is symmetrically arranged. The mating assembly is located on the side of the mounting bracket near the side plate.
[0008] The mating assembly includes a corner cylinder and a pressure plate. The corner cylinder is mounted on the top of the mounting bracket. The pressure plate is disposed on the output end of the corner cylinder and abuts against the upper surface of the limiting platform on the front side of the side plate.
[0009] The lead room radiation source protective cover processing equipment also includes a stabilizing mechanism, which includes a first locking block and a second locking block. The first locking block and the second locking block are integrally formed with the side plate and are slidably connected to the machine base.

Example
[0019] like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of the equipment for processing lead-lined radiation source shields. Figure 2 This is a front view of the core block 103. This utility model provides a processing equipment for a lead-room radiation source protective cover: it includes a machine base 101, a frame 102, and auxiliary mechanisms.

[0020] In this embodiment, the machine base 101 is integrally provided with a frame 102 on both sides, and the frame 102 has an L-shaped structure.

The specific connection method should refer to the working principle below, and the electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a well-known technology in the art. The following mainly introduces the working principle and process, and does not describe the electrical control.
[0021] The core block 103 is disposed on the upper side of the machine base 101. The limiting plate 104 is detachably installed on the rear side of the machine base 101. The abutment blocks 105 are symmetrically installed on both sides of the machine base 101 and symmetrically arranged on both sides of the limiting plate 104. The moving frame 106 is disposed on both sides of the core block 103. The electric spindle 107 is mounted on the moving frame 106. The cutting tool 111 is mounted on the electric spindle 107. The connecting frame 108 is disposed on the side of the moving frame 106 near the machine frame 102. The first servo electric cylinder 109 is mounted on the connecting frame 108, and its output end is connected to the moving frame 106. The second servo electric cylinder 110 is mounted on the machine frame 102, and its output end is connected to the connecting frame 108. The clamping device is disposed on the top of the core block 103, and the locking device is disposed on the front side of the core block 103. The core block 103 is designed according to the inner cavity shape of the protective cover. During the processing of the protective cover, the lead plate inside is fixed by countersunk bolts. The core block 103 is provided with a tool-avoiding groove structure that aligns with the protective cover to facilitate hole processing. The limiting plate 104 is fixed by positioning pins and bolts and is used to abut and limit the outer side of the rectangular plane on the rear side of the protective cover. The machine base 101 is provided with a stepped column structure on the rear side to facilitate the sliding installation and limiting of the top plate 112. The abutting block 105 can be integrally formed with the machine base 101 or fixed by positioning pins and bolts. After installation, it fits against the inclined side wall of the protective cover. The angle between the inclined surface of the protective cover and the lower plane is 135°. The cutting tool 111 can be a milling cutter or a drill bit. The first servo electric cylinder 109 and the second servo electric cylinder 110 are fixed by bolts respectively, and the output ends are connected to the connecting parts by bolts respectively. The clamping device is used to limit the core block 103, thereby limiting the protective cover and preventing it from moving during hole processing. The locking device is used to lock the clamping device.
[0022] Secondly, the top plate 112 is slidably connected to the limiting part on the rear side of the machine base 101 and abuts against the top of the core block 103; the side plate 113 is integrally formed with the top plate 112 and abuts against the front side of the core block 103. The top plate 112 is used to limit the top of the core block 103, and the side plate 113 is used to limit the front of the core block 103.
[0023] Then, the mounting bracket 114 is detached from the machine base 101 and is located on the front side of the machine base 101, and is symmetrically arranged; the mating assembly is located on the side of the mounting bracket 114 near the side plate 113. The mounting bracket 114 is U-shaped, and its bottom end is fixed by a positioning pin and bolts. The mating assembly is used to lock the side plate 113 in place.
[0024] Finally, the corner cylinder 115 is installed on the top of the mounting bracket 114; the pressure plate 116 is disposed on the output end of the corner cylinder 115 and abuts against the upper surface of the limiting platform on the front side of the side plate 113. The corner cylinder 115 is fixed to the top of the mounting bracket 114 by bolts, and the pressure plate 116 is fixedly installed on its output end. When it is activated, it drives the pressure plate 116 to rotate upward and press down towards the side plate 113 to fix the side plate 113. Afterward, the side plate 113 can be released by pushing the pressure plate 116 upward and rotating it away from the side plate 113.
[0025] When using this utility model to improve the processing efficiency of protective cover holes, the protective cover is first placed on the machine base 101 with its opening facing upwards. Then, the rear side of the protective cover is limited by the limiting plate 104, and the sides are limited by the abutment blocks 105. The core block 103 is then inserted. The mechanism of installing the top plate 112 and the side plate 113 is then used to fix the protective cover. Then, by controlling the first servo cylinder 109 and the second servo cylinder 110, the electric spindle 107 can be driven to approach the protective cover and move vertically. Furthermore, when the electric spindle 107 approaches the protective cover, it simultaneously drives the tool 111 to rotate. With the cooperation of the tool avoidance grooves on both sides of the core block 103 that align with the holes on the protective cover, the holes are processed. All four holes can be processed simultaneously, which greatly shortens the processing time and facilitates the rapid processing of installation holes for the protective cover of the lead room radiation source, thus improving processing efficiency.

The machine base 101 is provided with sliding grooves for the first locking block 201 and the second locking block 202 to facilitate their sliding insertion.
[0028] In this embodiment, the stability of the top plate 112 and the side plate 113 in limiting the protective cover and the core block 103 can be improved by further setting the first locking block 201 and the second locking block 202.
[0029] Finally, as Figure 4 As shown, where Figure 4This is a schematic diagram of the overall structure of a lead-room radiation source protective cover 200.
