Description

Technical Field

[0001] The utility model relates to the technical field of vehicle parts manufacturing, in particular to a temperature detection device of a tunnel type oven used for drying vehicle brake pads. Background Art

[0002] The brake pads of vehicles are usually dried in a tunnel oven. The heating temperature is different at different positions inside the tunnel oven. That is to say, a number of different temperature zones are set in the tunnel oven. The brake pads are sent in from one end of the tunnel oven and heated in a number of different temperature zones. A general tunnel oven is usually equipped with a temperature control instrument. However, due to the large internal volume of the oven, the reading of the temperature control instrument is difficult to match the actual temperature of the area where the brake pads are located. Therefore, it is usually necessary to send a temperature detection probe into the tunnel oven to detect the temperature values ​​of different temperature zones in real time, and compare the real-time detected temperature values ​​with the readings of the temperature control instrument, so as to make corresponding adjustments to the tunnel oven according to the processing technology of the brake pads. The temperature detection probe is connected to the front end of a connecting wire. When measuring the temperature, the temperature detection probe is inserted from the front end of the tunnel oven so that the temperature detection probe is connected to the conveying mechanism at the bottom of the tunnel oven for conveying brake pads. The temperature detection probe moves from the front end to the rear end of the tunnel oven along with the conveying mechanism to measure the temperature of each temperature zone inside the tunnel oven. When the temperature detection probe moves to the rear end of the tunnel oven, it is necessary to use the connecting wire to pull the temperature detection probe back. Due to the long length of the tunnel oven, the connecting wire is easy to get knotted inside the tunnel oven, making it difficult to pull the temperature detection probe back, and the connecting wire will be pressed by the brake pads inside the tunnel oven, making it difficult to pull the connecting wire, and even the connecting wire may be broken, causing the temperature detection probe to fall into the tunnel oven and be difficult to recover.

One end of the connecting wire is connected to the temperature detection probe. The connecting wire extends forward and passes through the wire slots on other brackets in turn, so that the other end of the connecting wire extends to the entrance at the front end of the tunnel oven.

[0011] A winding wheel is arranged at the entrance of the tunnel type oven, and the other end of the connecting wire is connected to the winding wheel so that the winding wheel can wind up the connecting wire or release the connecting wire when rotating.

The plurality of mounting racks 20 are located inside the tunnel oven 10 and are arranged along the length direction of the tunnel oven 10. Each mounting rack 20 is used to place a plurality of brake pads 90 arranged along the width direction of the tunnel oven 10. The conveying mechanism is located inside the tunnel oven 10 and is used to convey the plurality of mounting racks 20 from front to back. The conveying mechanism is not shown in the figure, and a chain conveying mechanism may be used. Specifically, the conveying mechanism includes two The two sides of the mounting frame 20 are respectively connected to the two chains; the above-mentioned multiple brackets 40 are arranged along the length direction of the tunnel oven 10, and the multiple brackets 40 correspond to one mounting frame 20 respectively, and the brackets 40 are connected to the corresponding mounting frames 20, so that the multiple brackets 40 are arranged at equal intervals along the length direction of the tunnel oven 10, and a wire clamping groove 41 is formed on the top of the bracket 40, the temperature detection probe 30 is connected to the bracket 40 located at the rear side, one end of the connecting line 50 is connected to the temperature detection probe 30, and the connecting line 50 extends forward and passes through the wire clamping grooves 41 on other brackets 40 in turn, so that the other end of the connecting line 50 crosses the tunnel oven 10 and extends to the entrance of the front end of the tunnel oven 10.

[0021] When measuring the temperature inside the tunnel oven 10, the first bracket 40 on the rear side moves backward from the entrance of the tunnel oven 10, and the temperature detection probe 30 is connected to the first bracket 40 on the rear side. As the first bracket 40 moves backward, the connecting line 50 is pulled, and the connecting line 50 is passed through the other multiple brackets 40 in sequence. During the movement of the temperature detection probe 30 inside the tunnel oven 10, the temperature of each temperature zone inside the tunnel oven 10 is measured. When the temperature detection probe 30 moves to the exit at the rear end of the tunnel oven 10, the temperature detection probe 30 completes the temperature detection process of all temperature zones inside the tunnel oven 10, and the temperature detection probe 30 is removed from the bracket 40. The connecting line 50 is pulled at the entrance at the front end of the tunnel oven 10. The connecting line 50 drives the temperature detection probe 30 to pass through the wire slots of multiple brackets 40 in sequence and is pulled to the front end entrance of the tunnel oven 10. When the temperature of the tunnel oven 10 is measured by the temperature detection probe 30, the connecting wire 50 is passed through the wire groove 41 at the top of the bracket 40 to avoid contact between the connecting wire 50 and the brake pad 90 on the mounting frame 20, and to prevent the brake pad 90 and the connecting wire 50 from interfering with each other. This can protect the brake pad 90 from being damaged by the connecting wire 50, and ensure that the connecting wire 50 can move smoothly inside the tunnel oven 10, and ensure that the temperature detection probe 30 can accurately detect the actual temperature of each temperature zone inside the tunnel oven 10. After the detection is completed, the temperature detection probe 30 can be quickly recovered to the entrance of the tunnel oven 10 by pulling the connecting wire 50 at the entrance of the tunnel oven 10, so that the recovery of the temperature detection probe 30 becomes simple and fast, and the temperature detection probe 30 recovered to the entrance of the tunnel oven 10 can be quickly used for the next temperature detection.

[0022] In the present invention, the wire clamping groove 41 is set as a spiral groove, and a receiving portion 412 for receiving the connecting wire 50 is formed at the center of the spiral groove, and an opening 411 is formed at the outer periphery of the spiral groove. The opening 411 allows the connecting wire 50 to be clamped into the spiral groove, so that the connecting wire 50 is finally in the receiving portion 412, and ensures that the connecting wire 50 can cross the receiving portion 412. The bracket 40 includes a support rod 42 extending in the height direction, and the wire clamping groove 41 is located at the top of the support rod 42. The wire clamping groove 41 can be a spiral groove formed by winding the upper part of the support rod 42 into a spiral shape. The wire clamping groove 41 is set as a spiral groove, so that the connecting wire 50 can be embedded in the wire clamping groove 41. After the connecting wire 50 is in the receiving portion 412 of the wire clamping groove 41, the spiral structure forms a maze-like structure to prevent the connecting wire 50 from escaping from the wire clamping groove 41, that is, to prevent the connecting wire 50 from separating from the bracket 40.

[0023] A row of baffles 21 are arranged along the width direction of the tunnel oven 10 on both sides of the mounting frame 20, and a groove is formed between two adjacent baffles 21 in each row of baffles 21. In this way, the two rows of baffles 21 form a row of grooves on both sides of the mounting frame 20, and the two side edges of the brake pads 90 are respectively clamped in the two opposite grooves on both sides of the mounting frame 20. In this way, multiple brake pads 90 are placed on the mounting frame 20, and the above-mentioned support rod 42 is detachably mounted on one of the baffles 21 of the mounting frame 20, so that the bracket 40 is connected to the mounting frame 20, while facilitating the rapid disassembly and assembly of the bracket 40 and the mounting frame 20. Specifically, a sleeve 43 is fixedly connected to the bottom of the support rod 42, and the sleeve 43 can be sleeved on one of the baffles 21 of the mounting frame 20, so as to realize the detachable connection between the support rod 42 and the baffle 21. The bracket 40 can be lifted upward to realize the separation of the bracket 40 and the mounting frame 20. A limit plate 44 is fixed on the outer circular surface of the sleeve 43, and the limit plate 44 is inserted in the gap formed between two adjacent brake pads 90. A limit structure is formed by the limit plate 44 and the two brake pads 90 to prevent the sleeve 43 from rotating relative to the bracket 40, thereby preventing the bracket 40 from rotating and causing the connecting rope 50 to become knotted. In this way, the bracket 40 can be used to better guide the connecting rope 50.

[0024] A winding wheel 11 is provided at the entrance of the front end of the tunnel oven 10, and the other end of the connecting wire 50 is connected to the winding wheel 11. When the internal temperature of the tunnel oven 10 is to be detected, the winding wheel 11 is rotated to release the connecting wire 50. When the temperature detection probe 30 is to be recovered, the winding wheel 11 is rotated in the opposite direction to wind the connecting wire 50 to pull the temperature detection probe 30, thereby realizing the recovery of the temperature detection probe 30.
