Technical Field

[0001] The utility model relates to the technical field of sensor auxiliary equipment, in particular to a fixing structure for a laser displacement sensor. Background Art

[0002] A laser displacement sensor is an instrument that uses laser as the active light source and performs displacement detection based on the triangulation principle. It mainly consists of a laser emitter, a laser detector, and a measurement circuit. It can accurately measure the displacement, thickness, and vibration changes of an object non-contact, and has the advantages of high measurement accuracy, fast response speed, and strong anti-photoelectric interference ability. It is widely used in the fields of precision measurement and defect detection.

Symmetrically distributed connecting rods are inserted into the outer wall of one side of the fixing plate, and limiting plates and pressing blocks are respectively fixed at both ends of the two connecting rods. A second telescopic spring is sleeved and movable on the rod wall of the connecting rod.

[0007] When disassembling and assembling the sensor body, by pulling the limiting plate, the pressing block is pulled away from the sensor body through the connecting rod. At this time, the second telescopic spring is compressed and contracted. Then, the fixing plate is lifted upward, so that the pressing plate squeezes the first telescopic spring to move upward until the sensor body is completely exposed. The sensor body is taken out from the top of the supporting block and a new sensor body is inserted into the top between the two supporting blocks. Release the lifting of the fixing plate. Under the push of the first telescopic spring, the pressing plate abuts against the top of the sensor body, and the second telescopic spring pushes the pressing block, so that the pressing block abuts against the outer wall of the sensor body.

[0008] Preferably, an arc-shaped groove is formed on the outer wall of one side of the positioning plate, and the arc-shaped groove is adapted to the outer wall of the sensor body.

[0009] The sensor body is in abutment with the positioning plate through the arc-shaped groove, preventing the sensor body from falling off from one side of the positioning plate.

[0010] Preferably, threads are engraved on the top end of the rod wall of the movable rod, and a limiting block is screwed onto the movable rod.

[0011] The screwed limiting block prevents the movable rod from falling off from the bottom of the top plate.

[0012] Preferably, a slider is fixed to the other end of the pressing plate, and a sliding groove is formed on the outer wall of one side of the positioning plate. The sliding groove and the slider form a sliding fit.

[0013] The slider moves along the sliding groove to guide and limit the up-and-down movement of the pressing plate.

[0014] Preferably, the first telescopic spring is located between the top plate and the pressing plate, and the second telescopic spring is located between the pressing block and the fixing plate.

[0015] The first telescopic spring pushes the pressing plate, causing the pressing plate to abut against the top of the sensor body. The second telescopic spring pushes the pressing block, causing the pressing block to abut against the outer wall of the sensor body.

[0016] Preferably, a groove is formed on the outer wall of the side of the pressing block close to the positioning plate, and the groove is adapted to the outer wall of the sensor body.

[0017] The first telescopic spring pushes the pressing plate, causing the pressing plate to abut against the top of the sensor body. The second telescopic spring pushes the pressing block, causing the pressing block to abut against the outer wall of the sensor body.

[0018] The beneficial effects of the present utility model are as follows:

[0019] By pulling the limiting plate, the pressing block is pulled away from the sensor body through the connecting rod. Then, the fixing plate is lifted upward, causing the pressing plate to squeeze the first telescopic spring and move upward until the sensor body is completely exposed. The sensor body is taken out from the top of the supporting block, and a new sensor body is inserted into the top between the two supporting blocks. The lifting of the fixing plate is released. Under the push of the first telescopic spring, the pressing plate abuts against the top of the sensor body, and the second telescopic spring pushes the pressing block, causing the pressing block to abut against the outer wall of the sensor body. This effectively solves the problem in the prior art that the traditional fixing structure cannot meet the requirements of quickly disassembling and assembling the laser displacement sensor and cannot cooperate well with the staff for daily work.

A first telescopic spring 8 is sleeved and movable on the rod wall of the movable rod 7. A pressing plate 10 is fixed at the bottom of the movable rod 7. A fixing plate 12 is fixed at one end of the pressing plate 10. Symmetrically distributed connecting rods 13 are inserted into the outer wall of one side of the fixing plate 12. Limiting plates 14 and pressing blocks 15 are fixed at both ends of the two connecting rods 13 respectively. A second telescopic spring 16 is sleeved and movable on the rod wall of the connecting rod 13;

[0027] An arc-shaped groove is formed on the outer wall of one side of the positioning plate 3, and the arc-shaped groove is adapted to the outer wall of the sensor body 1. The sensor body 1 is in contact with the positioning plate 3 through the arc-shaped groove, preventing the sensor body 1 from falling off from one side of the positioning plate 3. Threads are engraved on the top end of the rod wall of the movable rod 7, and a limiting block 9 is screwed on the movable rod 7, so that the movable rod 7 will not fall off from the bottom of the top plate 5 through the screwed limiting block 9. A slider 11 is fixed at the other end of the pressing plate 10. A sliding groove is formed on the outer wall of one side of the positioning plate 3, and the sliding groove forms a sliding fit with the slider 11.

[0028] The first telescopic spring 8 is located between the top plate 5 and the pressing plate 10, and the second telescopic spring 16 is located between the pressing block 15 and the fixing plate 12. The pressing plate 10 is pushed by the first telescopic spring 8 so that the pressing plate 10 abuts against the top of the sensor body 1. The second telescopic spring 16 pushes the pressing block 15 so that the pressing block 15 abuts against the outer wall of the sensor body 1. A groove is formed in the outer wall of the pressing block 15 on the side close to the positioning plate 3, and the groove is adapted to the outer wall of the sensor body 1.
