Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a wireless slip detection device. Background Art

[0002] During the tube hole processing of header products or drum products, it is necessary to clamp the header products or drum products by the chuck jaws, and the slewing support drives the chuck to rotate a specific angle, and then the punching device is used to process the circular hole on the workpiece (header products or drum products). When the workpiece rotates, it is necessary to avoid relative displacement between the workpiece and the chuck jaws due to slipping. If slipping occurs, the position of the tube hole will deviate, and in severe cases, the workpiece will be scrapped. Therefore, it is necessary to detect the relative slip of the workpiece in order to detect the slipping of the workpiece in time and prompt the operator to stop the machine for maintenance.

[0003] Traditional slippage detection devices are connected to cables. When used for pipe hole processing of header or drum products, the workpiece is clamped by the chuck jaws during processing, and the chuck is rotated by the rotary support. The cables are easily tangled, making traditional detection devices impossible to install. Utility Model Content

[0004] In order to solve the deficiencies in the above-mentioned prior art, the purpose of the present utility model is to provide a wireless slip detection device, which can quickly and accurately fix the infrared sensor directly below the infrared transmitter, facilitate the disassembly or installation of the infrared sensor, and can promptly detect the slippage of the workpiece, and prompt the operator to stop the machine for maintenance, thereby reducing product failures caused by slippage during the pipe hole processing of header products or drum products, and reducing losses caused by product failures.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A wireless slip detection device is provided, comprising an infrared transmitter, an infrared sensor, and a mounting plate fixed to the side surface of a chuck. A suspension plate is fixed to the top of the mounting plate, a guide plate is fixed to the lower surface of the suspension plate, a slider is slidably engaged with one side of the guide plate, and a positioning plate is fixed to one side of the slider.

[0010] Furthermore, a support plate is fixed on one side of the mounting plate, and a reinforcing rib is fixed between the support plate and the mounting plate. A group of bolt columns are also fixed on the upper surface of the support plate. The top end of the bolt column slides through the hanging plate and is also equipped with a nut. The side surface of the bolt column is covered with an anti-slip pad.

[0011] Furthermore, a sliding groove is provided on one side of the guide plate, the slider is slidably fitted in the sliding groove, two guide columns are fixed to the bottom of the sliding groove, and the slider is slidably sleeved on the outside of the guide columns.

[0032] Example 1:

[0033] like Figure 1-5 The wireless skid detection device shown includes an infrared transmitter 3, an infrared sensor 7, and a mounting plate 1 fixed to the side of the chuck. A hanging plate 2 is fixed to the top of the mounting plate 1, and a guide plate 4 is fixed to the lower surface of the hanging plate 2. A slider 5 is slidably engaged with one side of the guide plate 4, and a positioning plate 6 is fixed to one side of the slider 5.

[0034] A positioning column 8 is fixed on the top of the infrared sensor 7. The top of the positioning column 8 slides through the positioning plate 6 and is fixed with a receiving head 9. A permanent magnet 10 is fixed on the bottom of the infrared sensor 7. The permanent magnet 10 is adsorbed and fixed on the surface of the workpiece.

[0035] The infrared emitter 3 is fixed on the lower surface of the suspension plate 2, and the infrared emitter 3 is located directly above the receiving head 9;

[0036] A slide groove 19 is provided on one side of the guide plate 4, and the slider 5 is slidably fitted in the slide groove 19. Two guide posts 20 are fixed to the bottom of the slide groove 19, and the slider 5 is slidably sleeved on the outside of the guide posts 20.

[0037] A wireless signal transmission module is provided inside the infrared sensor 7 , and the signal sent by the wireless signal transmission module is received by a control system that controls the rotation of the chuck.

[0038] In the present application, the mounting plate 1 is fixed to the outside of the chuck by screws, the mounting plate 1 is perpendicular to the chuck, the infrared emitter 3 is fixed to the lower surface of the suspension plate 2, the slider 5 is placed at the top of the slide groove 19, and a clearance groove is opened on the slider 5. When the slider 5 slides down in the slide groove 19, the guide column 20 slides through the clearance groove, and then the positioning column 8 slides through the positioning circular groove 21. At this time, when the positioning plate 6 is moved downward, the infrared sensor 7 will drop vertically with the positioning plate 6 until the permanent magnet 10 is adsorbed and fixed on the workpiece, and then the slider 5 is slid up to the top, and then the slider 5 is taken out of the slide groove 19, and the positioning installation of the infrared sensor 7 is completed;

[0039] After the infrared transmitter 3 and the infrared sensor 7 are started, the infrared beam emitted by the infrared transmitter 3 is received by the receiving head 9. After the infrared sensor 7 senses the infrared signal, it sends the received signal wirelessly to the control system that controls the rotation of the chuck through the signal transmission module. If the workpiece and the chuck jaws produce relative displacement, the infrared sensor 7 and the infrared transmitter 3 are no longer in the same straight line. At this time, the receiving head 9 will not receive the infrared light, and the infrared sensor 7 will transmit the signal of not receiving the infrared light to the control system through the signal transmission module. At this time, the control system will determine that the workpiece has slipped, and the control system will alarm and shut down for maintenance.

[0040] In order to facilitate the disassembly or installation of the fixed hanging plate 2, in this embodiment, a buckle groove 11 is opened at the top of the mounting plate 1, a bolt column 14 is fixed to the bottom of the buckle groove 11, a buckle plate 12 is fixed to one end of the hanging plate 2, and a baffle 13 is fixed to one end of the buckle plate 12. The buckle plate 12 slides in the buckle groove 11, and the top of the bolt column 14 slides through the buckle plate 12 and is adapted with a nut 15.

A group of bolt columns 14 are also fixed to the upper surface of the support plate 17. The top of the bolt column 14 slides through the hanging plate 2 and is also equipped with a nut 15. The side surface of the bolt column 14 is covered with an anti-slip pad 16. The provision of the anti-slip pad 16 makes the fixation between the hanging plate 2 and the mounting plate 1 more secure.

[0042] In order to facilitate the top of the infrared sensor 7 to slide through the positioning plate 6, in this embodiment, the positioning plate 6 is an L-shaped structural plate, and a positioning circular groove 21 is opened at the bottom of the positioning plate 6. The positioning column 8 slides in the positioning circular groove 21, and the permanent magnet 10 is adsorbed and fixed on the side surface of the workpiece.

[0044] The features that are the same as those of the first embodiment are not described in detail. The features that are different from the first embodiment are as follows: Figure 6 As shown, a plurality of suction cups 22 are fixed to the bottom of the infrared sensor 7. The infrared sensor 7 is fixed to the workpiece by adsorption through the suction cups 22. By utilizing the negative pressure principle, the suction cups 22 and the infrared sensor 7 can be tightly adsorbed and fixed to the surface of the workpiece, making it convenient to disassemble or install the infrared sensor 7.
