Description

Technical Field

[0001] This utility model relates to a riveting device, and more particularly to a feeding and positioning mechanism for highly reliable feeding and positioning of rivets for oil pipe joints. Background Technology

[0002] The spherical connectors currently used on motorcycles, ATVs, off-road vehicles, electric vehicles, and bicycles are all types of hydraulic hose connectors. These connectors vary depending on the vehicle model and layout requirements, and are mainly divided into straight connectors and bent connectors. The manufacturing process of straight or bent connectors generally involves: 1. Separately molding the connector blank and core; 2. Riveting the molded connector blank and core together. The main difference between straight and bent connectors is that bent connectors involve a bending process after riveting the connector blank and core together.

[0003] In the above process, the existing riveting between the connector blank and the core of the oil pipe connector is generally achieved by automated equipment. That is, the automated equipment usually involves two vibratory plates for placing the connector blank and the core separately, and two feeding tracks connected to the two vibratory plates respectively. Specifically, the material is fed through the two feeding tracks respectively, and then riveting is performed at the intersection.

[0004] In addition, most of the automated equipment currently on the market that rivets the connector blanks and cores for oil pipe fittings uses the following specific riveting process: a limiting device is set on the side near the connector blank to hold the connector blank out. The limiting device is driven by something similar to a cylinder. By extending or retracting the limiting device toward the connector blank, the connector blank is held in place. (The shape of the limiting device is similar to a long U-shaped groove opened on one end of a metal plate to hold the connector blank. The two sides of the groove hold the part between the "fisheye" of the connector blank and the connector.)

[0005] The core part is similar to being pushed to one side of the rivet joint involved in the riveting equipment by the action of the pusher. When the pusher pushes the core out, the joint blank is also stuck in the position of the corresponding limiting part. The rivet joint moves towards the joint blank to realize the riveting of the core onto the joint blank.

[0006] However, when using the aforementioned automated equipment to rivet the connector blank and the core, the automated equipment can only detect whether the core is pushed over when the pusher is pushed over, but cannot ensure whether the pushed core is skewed before riveting. That is, it cannot ensure whether the core, the hole on the connector blank, and the riveting joint are on the same straight line before riveting. Therefore, there is a certain probability that the riveted product may be a defective product that is damaged. Summary of the Invention

[0007] In view of the above shortcomings, this utility model provides a highly reliable rivet feeding and positioning mechanism for oil pipe joints that can guarantee the product qualification rate of oil pipe joints during the riveting stage.

[0008] To achieve the above objectives, this utility model employs a highly reliable feeding and positioning mechanism for rivets used in oil pipe joints. This mechanism includes a core feeding mechanism, a core feeding track connected to the core feeding mechanism, a core pushing mechanism, a core placement area, and a pressing mechanism. The core pushing mechanism pushes cores that exit through the core feeding track into the core placement area. The pressing mechanism includes a pressing part located on one side of the core placement area. This pressing part performs pressing and repositioning actions on the cores placed in the core placement area, ensuring that the axis of the cores in the core placement area is aligned with the riveting part on the external rivet device and the axis of the joint blank in the riveting area.

[0009] The present invention is further configured such that the pressing mechanism also includes a spring-loaded part, which is linked to the pressing part. Through the spring-loaded part, the pressing part is lifted by force, and the core is pushed to the core placement area by the core pushing mechanism. The pressing part is lifted by the pushing force of the core pushing mechanism and performs the pressing and adjusting action on the core.

[0010] The present invention is further configured such that a chamfer is formed on the end of the pressing part relative to the side facing the core placement area, and the force points for lifting the pressing part are distributed on the chamfer. A position calibration groove for core calibration is provided on the end face of the pressing part. The core is compacted through the position calibration groove, and the position of the core corresponds to that of the connector blank. The chamfer is an arc chamfer or a bevel chamfer. The position calibration groove is an arc groove or a V-shaped groove with the bottom facing upward.

[0011] The present invention is further configured such that the core pushing mechanism includes a pushing telescopic part, the core placement area is distributed in the extension direction of the pushing telescopic part and is linked with the pushing telescopic part. During the pushing stage of the core pushing mechanism, the core is pushed out through the pushing telescopic part, and the core placement area extends synchronously within the pushing telescopic part and extends to below the pressing part.

[0012] The beneficial effects of this utility model are as follows: By including a highly reliable rivet feeding and positioning mechanism for the rivet device used on the oil pipe joint, which involves a core feeding mechanism, a core feeding track connected to the core feeding mechanism, and a core pushing mechanism, a pressing mechanism is also included. The pressing mechanism includes a pressing part. Thus, when the rivet used on the oil pipe joint is being installed, the core passes through the core feeding track and is pushed to the core placement area by the core pushing mechanism. When the core enters the core placement area, the pressing part of the pressing mechanism presses the core that has entered the core placement area accordingly, and adjusts the position of the core with positional deviation. After adjustment, the axis of the core in the core placement area is aligned with the riveting part on the rivet device and the axis of the joint blank in the riveting area. Therefore, during the riveting process, the riveted oil pipe joint will not be accidentally damaged due to positional deviation, thus affecting the product qualification rate.

[0021] like Figure 1-8As shown, a specific embodiment of this utility model is a highly reliable feeding and positioning mechanism for rivets used in an oil pipe connector c. It includes a core feeding mechanism 1, a core feeding track 2 connected to the core feeding mechanism 1, a core pushing mechanism 3, a core placement area 31, and a pressing mechanism 5. The core pushing mechanism 3 pushes the core b, which is discharged from the outlet 32 ​​of the core feeding track 2, onto the core placement area 31. The pressing mechanism 5 includes a pressing part 51, which is distributed on one side of the core placement area 31. The pressing part 51 performs pressing and adjusting actions on the core b placed on the core placement area 31, so that the axis of the core b on the core placement area 31 is aligned with the axis of the riveting part 41 on the external rivet device and the axis of the connector blank a on the riveting area.

[0022] The aforementioned highly reliable rivet feeding and positioning mechanism for the rivet device used on the tubing connector c, in addition to the core feeding mechanism 1, the core feeding track 2 connected to the core feeding mechanism 1, and the core pushing mechanism 3, also includes a pressing mechanism 5, which includes a pressing part 51. Thus, when the rivet is installed on the tubing connector c, the core b passes through the core feeding track 2 and is pushed onto the core placement area 31 by the core pushing mechanism 3. Simultaneously, when the core b enters the core placement area 31... The pressing part 51 of the pressing mechanism 5 presses the core b that has entered the core placement area 31, and adjusts the position of the core b that has a positional deviation. After adjustment, the axis of the core b in the core placement area 31 is aligned with the axis of the riveting part 41 on the riveting device and the axis of the joint blank a in the riveting area. This prevents the riveted oil pipe joint c from being accidentally damaged due to positional deviation during the riveting process, thus affecting the product qualification rate.

[0023] like Figure 1-4As shown, the pressing mechanism 5 also includes a spring-loaded part 52, which is linked to the pressing part 51. The spring-loaded part 52 causes the pressing part 51 to lift under pressure, pushing the core b onto the core placement area 31 via the core pushing mechanism 3. The pressing part 51 is lifted by the pushing force of the core pushing mechanism 3, thus performing a pressing and adjusting action on the core b. This ensures reliable pressing of the core b by the pressing mechanism 5, achieving reliable pressing and adjusting while avoiding the extension process of the core b during feeding or riveting of the riveting part 41 if the pressing part 51 is not spring-loaded. In the process, there is a possibility that the impact may accidentally damage the pressing mechanism 5. In addition, by designing the pressing part 51 to be able to bounce up under force, when the core pushing mechanism 3 pushes the core b onto the core placement area 31, the riveting mechanism 4 on the external riveting device can also directly drive the riveting part 41 toward the riveting area to perform the riveting extension action. Thus, there is no need for feeding mechanisms like most existing ones, which need to retract after feeding before other mechanisms can enter, thus avoiding interference. Therefore, the driving process of this invention can be simplified compared to existing ones.

[0024] like Figure 2-4 As shown, a chamfer 511 is formed on the end of the pressing part 51 facing the core placement area 31. The force points for lifting the pressing part 51 are distributed on the chamfer 511. A position calibration groove 512 for calibrating the core b is provided on the end face of the pressing part 51. The core b is compacted through the position calibration groove 512, and the position of the core b corresponds to that of the connector blank a. The chamfer 511 is an arc chamfer or a bevel chamfer. The position calibration groove 512 is an arc groove or a V-shaped groove with the bottom of the groove facing upward. This allows the core b to be conveniently calibrated when it is pushed to the core placement area 31 by the core pushing mechanism 3, and also ensures the convenience of the drive limit design of this utility model.

[0025] like Figure 2-4As shown, the core pushing mechanism 3 includes a pushing telescopic part 32, and a core placement area 31 is distributed in the extension direction of the pushing telescopic part 32 and is linked with the pushing telescopic part 32. During the pushing stage of the core pushing mechanism 3, the core b is pushed out through the pushing telescopic part 32, and the core placement area 31 extends synchronously within the pushing telescopic part 32 and extends below the pressing part 51. This ensures the convenience of the design of the core placement area 31, that is, the core placement area 31 can extend along with the core pushing mechanism 3 when feeding in the direction of the riveting area, and synchronously place the core b. After the core b is pushed away by the riveting part 41 and riveted to the joint blank a on the core placement area 31, the pushing telescopic part 31 extends... When part 32 retracts into the core feeding mechanism 3, the core placement area 31 also retracts into the pushing extension part 32. During the stage when the pushing extension part 32 pushes out the next core b in the core feeding track 2, the corresponding core placement area 31 also extends out again. This design avoids the situation where if the core placement area 31 is always below the pressing part 51, the pressing part 51 will continuously press against the core placement area 31, meaning the spring part 52 will always be in a compressed state. If this continues for a long time, it may affect the elastic rebound ability of the pressing part 51, causing the spring rebound ability of the pressing part 51 to become less sensitive after a period of use, thus affecting the reliability of this utility model.
