Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to an operating bed head and leg board interchange detection device. Background Art

[0002] Position detection devices are mainly used in closed-loop and semi-closed-loop systems. The detection device detects the actual displacement of the actuator by direct or indirect measurement, and then feeds it back to the CNC device and compares it with the command displacement. If there is a difference, a motion control signal is issued to control the moving parts of the CNC machine tool to move in the direction to eliminate the difference. The command signal is continuously compared with the feedback signal, and then control is performed until the difference is 0 and the movement stops. The position control of the computer numerical control system compares the theoretical position calculated by interpolation with the actual feedback position, and uses the difference to control the feed motor. The acquisition of the actual feedback position is completed by some position detection devices. These detection devices include rotary transformers, induction synchronizers, pulse encoders, gratings, magnetic gratings... For CNC machine tools that use semi-closed-loop control, the closed loop does not include mechanical transmission links. Its position detection device generally uses a rotary transformer or a high-resolution pulse encoder installed at the end of the feed motor or the lead screw. Every rotation of the rotary transformer (or pulse encoder) by a certain angle strictly corresponds to a certain distance moved by the workbench. By measuring the angular displacement of the motor or the lead screw, the linear displacement of the worktable is indirectly measured. For CNC machine tools that use a closed-loop control system, the linear displacement of the worktable should be measured directly. Measuring devices such as induction synchronizers, gratings, and magnetic gratings can be used. The worktable directly drives the sliding scale of the induction synchronizer to move, and at the same time, it cooperates with the fixed scale installed on the machine tool bed to measure the actual displacement value of the worktable. The machining accuracy of CNC machine tools is mainly determined by the accuracy of the detection system. The minimum displacement that the displacement detection system can measure is called resolution. The resolution depends not only on the detection element itself, but also on the measurement circuit. The main requirements of CNC machine tools for detection devices are: high reliability and high anti-interference, meet the accuracy and speed requirements, easy to use and maintain, and low cost. For different types of CNC machine tools, due to different working conditions and detection requirements, the following different detection methods can be used. (1) Incremental and absolute; (2) Digital and analog.

[0004] However, there is a disadvantage that the interchangeable bed used in the device cannot achieve interchangeability between the head and the leg board, which results in the patient's orientation being fixed to one side, which is troublesome. Utility Model Content

[0005] The purpose of the utility model is to provide a surgical bed head and leg board interchange detection device to solve the problem proposed in the above background technology that the interchangeable bed used in the device cannot be interchanged with the head and leg boards, which results in the patient's orientation being fixed in one direction, which is quite troublesome.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a surgical bed head leg board interchange detection device, comprising a main body, a fixing structure is installed on the inner side of the main body, a reinforcement structure is installed on one side of the main body, the main body comprises a main shell, a first spring, a second spring, a detection plate, and a detector, the first spring is installed on the inner side of the main shell, and the second spring is installed on the inner side of the main shell.

[0008] Furthermore, a detection plate is installed on the upper side of the first spring and the second spring, and a detector is installed on the lower side of the detection plate.

[0009] Furthermore, the fixing structure includes a first fixing column, a second fixing column, a fixed main column, a third fixing column, a fixing screw, a fixing nut, a fixed limiter, a fixed connecting column, a fourth fixing column, a third spring, a fifth fixing column, and a sixth fixing column. The first fixing column is installed on the inner side of the main shell, and the second fixing column is installed on the inner side of the main shell.

[0010] Furthermore, a fixed main column is installed on the outer sides of the first fixed column and the second fixed column, a third fixed column is installed on one side of the fixed main column, and a fixing screw is installed on the inner side of the third fixed column.

[0011] Furthermore, a fixing nut is installed on the outer side of the fixing screw, a fixing limiter is installed on the outer side of the fixing screw, and a fixing connecting column is installed on the outer side of the fixing screw.

[0012] Furthermore, a fourth fixing column is installed on one side of the fixed connecting column, a third spring is installed on one side of the fourth fixing column, a fifth fixing column is installed on one side of the third spring, and a sixth fixing column is installed on one side of the fifth fixing column.

[0013] Furthermore, the reinforcement structure includes a first fixed block, a second fixed block, a third fixed block, an upper reinforcement plate, a telescopic reinforcement plate, and a lower reinforcement plate. The first fixed block is installed on the upper side of the main shell, the second fixed block is installed on one side of the first fixed block, and the third fixed block is installed on one side of the second fixed block.

[0015] The utility model has the following beneficial effects:

[0016] (1) The utility model has a fixed structure. When the headboard or leg board is put in, the fixed structure will be squeezed by the headboard, and the fifth fixed column and the sixth fixed column will extend backward under the action of the third spring, and the lateral balance of the headboard or the leg board will be maintained. If the headboard or the leg board is not in the same horizontal plane front and back after being placed in the fixed structure, it means that the angles in the interchangeable structure are asymmetric. In addition, a first spring, a second spring, a detection plate and a detector are also provided in the main body. When the headboard or the leg board is put into the fixed structure, the detection plate will give the first spring and the second spring a force downward along with the headboard. When the detection plate contacts the detector, it means that the force applied by the headboard to the detection plate is too large, thereby concluding that the interchangeability of the headboard and the leg board is unbalanced.

[0017] (2) The present invention also provides a reinforcement structure. When the headboard or legboard is placed in the fixed structure and the detector detects an imbalance in the interchange between the headboard and the legboard, the reinforcement structure will reduce the distance between the upper reinforcement plate and the lower reinforcement plate by shortening the length of the reinforcement plate, thereby achieving the effect of fixing the headboard or legboard and preventing the headboard or legboard from falling due to unsuccessful interchange of the headboard or legboard.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
