Abstract
Description
Technical Field
[0001] The utility model relates to the field of production safety, in particular to a device for detecting the locking condition of a rotary oil cylinder. Background Art
[0002] The rotary cylinder is one of the commonly used components in CNC lathes. It is used in conjunction with a high-speed power chuck or other power fixtures to provide clamping power. When the rotary cylinder is working, the piston shaft inside it will rotate with the chuck, so the oil return cover on the outside needs to be fixed during use and testing. When the machine tool is tested, the tested cylinder is likely to be a substandard product and may be locked. Once the oil return cover and the piston shaft are locked, there will be a great safety hazard during high-speed rotation. If this situation can be discovered in the early stage of locking, the above safety hazards can be eliminated.
[0003] Therefore, a method or device capable of solving the above problems is now needed. Summary of the invention
[0004] The utility model aims to solve the above-mentioned deficiencies in the prior art and proposes a detection device with simple structure, ingenious design and reasonable layout, which can automatically control the rotary cylinder to stop working in the early stage of the rotary cylinder locking.
[0005] The technical solution of the utility model is: a rotary cylinder locking condition detection device, characterized in that: the device comprises a bracket 1, a shaft sleeve 2 is arranged at the top end of the bracket 1, a trigger shaft 3 distributed along the X-axis direction is movably connected in the shaft sleeve 2, a first limit block 4 and a second limit block 5 are arranged on the trigger shaft 3, the first limit block 4 and the second limit block 5 are respectively located at the two ends of the shaft sleeve 2, a spring 6 is sleeved on the trigger shaft 3, and the spring 6 is located between the first limit block 4 and the shaft sleeve 2, a limit frame 7 is arranged at one end of the trigger shaft 3, the oil discharge port 8 of the rotary cylinder is located in the limit frame 7, a trigger block 9 is arranged at the other end of the trigger shaft 3, and a sensor 10 matching the trigger block 9 is arranged on the bracket 1.
[0006] The bracket 1 is movably sleeved in a supporting sleeve 11, and a top screw 12 matching the bracket 1 is threadedly connected to the supporting sleeve 11. The bottom end of the supporting sleeve 11 is a base 13, and the base 13 is fixed to a basic platform by bolts 14. The bolts 14 are connected to long holes 15 opened on the base 13, and the long holes are distributed along the Y-axis direction.
[0007] The inner wall of the limit frame 7 close to the shaft sleeve 2 is a trigger contact surface 16, and the trigger contact surface 16 forms an angle of 10-20 degrees with the vertical direction.
[0008] Compared with the prior art, the utility model has the following advantages:
[0009] The rotary cylinder locking detection device of this structural form has a simple structure, ingenious design and reasonable layout. It designs a special structure to solve the problem of rotary cylinder locking that may occur during the machine tool test experiment. A limit frame is set outside the oil discharge port of the rotary cylinder. Once the rotary cylinder is locked and the frame part is reversed, the oil discharge port will collide with the limit frame and drive the trigger shaft connected to the limit frame to move. In this way, the sensor set at the other end of the trigger shaft will detect the signal, thereby judging that the rotary cylinder has locked at this time. At this time, the sensor sends a signal to the control system, and the control system controls the rotary cylinder to stop working to prevent accidents. At the same time, it can also make adjustments within a certain range in the plane and vertical direction to adapt to rotary cylinders of different specifications, and has good applicability. In addition, the manufacturing process of this detection device is simple and the manufacturing cost is low. Therefore, it can be said that it has many advantages and is particularly suitable for promotion and application in this field. Its market prospects are very broad. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The specific implementation of the present utility model will be described below in conjunction with the accompanying drawings. Figure 1 , Figure 2 , Figure 3 As shown: a rotary cylinder locking condition detection device, which includes a bracket 1, a shaft sleeve 2 is arranged at the top of the bracket 1, a trigger shaft 3 distributed along the X-axis direction is movably connected in the shaft sleeve 2, a first limit block 4 and a second limit block 5 are arranged on the trigger shaft 3, the first limit block 4 and the second limit block 5 are respectively located at the two ends of the shaft sleeve 2, a spring 6 is sleeved on the trigger shaft 3, and the spring 6 is located between the first limit block 4 and the shaft sleeve 2, a limit frame 7 is arranged at one end of the trigger shaft 3, the oil discharge port 8 of the rotary cylinder is located in the limit frame 7, a trigger block 9 is arranged at the other end of the trigger shaft 3, and a sensor 10 matching the trigger block 9 is arranged on the bracket 1.
[0014] The bracket 1 is movably sleeved in a supporting sleeve 11, and a top screw 12 matching the bracket 1 is threadedly connected to the supporting sleeve 11. The bottom end of the supporting sleeve 11 is a base 13, and the base 13 is fixed to a basic platform by bolts 14. The bolts 14 are connected to long holes 15 opened on the base 13, and the long holes are distributed along the Y-axis direction.
[0015] The inner wall of the limit frame 7 close to the shaft sleeve 2 is a trigger contact surface 16, and the trigger contact surface 16 forms an angle of 10-20 degrees with the vertical direction.
[0016] The working process of the rotary cylinder locking condition detection device of the utility model embodiment is as follows: the device is arranged near the rotary cylinder to ensure that the oil discharge port 8 of the rotary cylinder is located in the limit frame 7, but the oil discharge port 8 does not contact the inner wall of the limit frame 7;
[0017] In the normal working state, since the oil discharge port 8 is not in contact with the limit frame 7, the trigger shaft 3 is not subjected to force. Therefore, under the action of the spring 6, the trigger shaft 3 is close to the oil discharge port 8. At this time, the trigger block 9 at its end does not trigger the sensor 10, and the control system marks the current state as the normal working state.
[0018] Once the rotary cylinder is locked, it will cause the frame part to reverse. At this time, the oil discharge port 8 of the rotary cylinder will swing with the movement of the frame part. When the oil discharge port 8 swings, it will contact the trigger contact surface 16 and push the limit frame 7 and the trigger shaft 3 connected thereto to move. The movement of the trigger shaft 3 will cause the trigger block 9 to move to the sensor 10 and trigger the sensor 10. The sensor 10 sends a signal to the control system. The control system determines that the current state is an abnormal state, and automatically controls the rotary cylinder to stop working.
[0019] During the above movement, the spring 6 is compressed.
[0020] When the staff finds that the rotary cylinder stops working, it means that an abnormality has occurred, so they will conduct manual intervention. After the fault is eliminated, the oil discharge port 8 will be corrected back to the initial position, and the trigger shaft 3 without external force will return to its original position under the action of the spring 6.
[0021] The relative height of the sleeve 2 can be adjusted. After adjusting to the appropriate height, the bracket 1 and the support sleeve 11 can be fixed using the top screw 12; the base 13 can also be adjusted in the Y-axis direction relative to the base platform, thereby realizing the adjustment of the limit frame 7 in the Y-axis direction, so that the device can be adapted to a variety of rotary cylinders of different specifications.
