Description

Technical Field

[0001] The utility model belongs to the field of automatic processing technology for parts and components, and relates to a passive spiral bevel gear channel sliding feeding device. Background Art

[0002] Robots are currently being used in the rear axle final reducer gear manufacturing industry, significantly improving automation and product quality. However, the corresponding automated loading devices for gear lathes prior to machining have been slow to keep pace with this development.

[0003] Currently, most domestic factories rely on manual lathe loading and start-up, which is labor-intensive and inefficient. Automated processing of passive spiral bevel gears is difficult and costly. High friction when the spindle grips the passive spiral bevel gears can easily cause the clamp to deflect, leading to batch scrap during mass production. Furthermore, deflected passive spiral bevel gears can collide with the lathe, posing a safety hazard. This can lead to equipment downtime, impacting order delivery, and wasting production costs.

[0004] In the existing automation design, a set of passive spiral bevel gear material channel sliding loading device can realize automatic docking with the robot, material channel, and spindle. The entire grabbing process of the machine tool is as follows: the robot grabs the passive bevel gear and places it on the loading base. When the position sensor detects the presence of a workpiece, the PLC transmits the signal, and the cylinder drives the loading claw to expand. The loading claw tightens the inner hole of the passive bevel gear, and the material bin slides as a whole to the photo area to identify the passive bevel gear tooth groove. After the tooth groove identification is completed, the material bin enters the loading position. After the material bin reaches the loading position, the cylinder drives the loading claw to release and wait for the spindle to grab the material. The spindle grabs the passive bevel gear in the material channel for processing after the passive spiral bevel gear tooth groove is indexed according to the photo. The difficulty of the whole process is: when the spindle grabs the passive spiral bevel gear, the friction between the end face of the passive spiral bevel gear and the loading base is relatively high, so the spindle ball head is not easy to insert into the tooth groove of the passive spiral bevel gear, which makes the passive spiral bevel gear easy to be clamped. During batch processing, the clamping will cause the batch to be scrapped. At the same time, if the deflection of the passive spiral bevel gear is large, it may cause a collision with the lathe, posing a safety hazard. Utility Model Content

[0005] The technical problem to be solved by the utility model is: how to improve the processing accuracy of the passive spiral bevel gear and reduce the potential safety hazards in the processing process, thereby providing a passive spiral bevel gear material channel sliding feeding device.

[0006] The technical solution of the utility model is specifically as follows:

[0007] A passive spiral bevel gear material channel sliding feeding device includes a universal ball for placing a passive spiral bevel gear, the universal ball is embedded in a feeding base, the feeding base is installed on a support frame, the support frame is a circular ring, and at least one feeding claw base is slidably arranged on the support frame, the feeding claw bases are distributed along the radial direction of the support frame, and all feeding claw bases are cocircular, and a central air channel is arranged in the center of all feeding claw bases; a feeding claw is connected to each feeding claw base by a bolt; and it also includes a cylinder, the air pipe of the cylinder is connected to the air channel, and the air channel is connected to the central air channel of the feeding claw base.

[0008] At least three universal balls are installed on the loading base, and each universal ball contacts the end face of the workpiece.

[0009] Each loading claw is mounted on the loading claw base by two bolts.

[0010] The feeding claws include two-claw feeding, three-claw feeding and four-claw feeding.

[0011] A position sensor is provided on one side of the support frame, and the position sensor is a proximity switch.

[0012] The beneficial effects of the utility model are:

[0013] 1. The utility model adopts a positioning form that combines a universal ball with a feeding claw. The end face positioning of the universal ball effectively reduces the friction resistance generated by the heavy passive spiral bevel gear during the positioning process, and realizes the repeatability, accuracy and reliability of automatic loading of the machine tool, replacing manual loading and unloading, which can reduce labor intensity, improve processing efficiency and reduce material costs.

[0014] 2. The diameter direction of the utility model can be adjusted quickly. By replacing the loading claws, it can be compatible with the positioning of all series of passive gears, greatly reducing production changes. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figure 1 、 Figure 2As shown, a passive spiral bevel gear material channel sliding feeding device includes a universal ball 2 for placing a passive spiral bevel gear 1, the universal ball 2 is embedded in a feeding base 6, and the feeding base 6 is mounted on a support frame 7; the support frame 7 is a circular ring, and at least one feeding claw base 4 is slidingly arranged on the support frame 7, and the feeding claw bases 4 are distributed along the radial direction of the support frame 7, and all the feeding claw bases 4 are cocircular, and a central air channel is arranged in the center of all the feeding claw bases 4; each feeding claw base 4 is connected to a feeding claw 3 by bolts. It also includes a cylinder, the air pipe of the cylinder is connected to the air channel 8, and the air channel 8 is connected to the central air channel of the feeding claw base 4. In this way, when the cylinder is actuated, the gas enters the central air channel through the air channel 8, causing the feeding claw base 4 to slide radially outward, so that the feeding claw base 4 drives the feeding claw to open outward, and the cylinder provides power for positioning the feeding claw 3.

[0019] Furthermore, at least three universal balls 2 are installed on the loading base 6 , each universal ball 2 contacts the end face of the workpiece, and the universal ball 2 plays a supporting role and reduces the movement resistance of the workpiece. The universal ball 2 is embedded in the loading base 6 .

[0020] Furthermore, each loading claw 3 is mounted on the loading claw base 4 by two bolts.

[0021] Furthermore, the feeding claws 3 include two feeding claws, three feeding claws, and four feeding claws.

[0022] Furthermore, the loading claw 3 includes an integrated loading base and a split loading base.

[0023] Furthermore, a position sensor 5 is provided on one side of the support frame 7. The position sensor 5 is a proximity switch. When the feeding claw base 4 is opened outward, the position sensor 5 can perform position sensing. The position sensor 5 senses whether the feeding claw 3 reaches the tightening position.

[0024] The working principle of this utility model is:

[0025] The robot places the passive bevel gear 1 on a loading base 6 embedded with a universal ball joint 2. When the pneumatic cylinder is activated, air enters the central airway through airway 8, causing the loading claw base 4 to slide radially outward. This causes the loading claw base 4 to open, allowing the loading claw 3 to enter the inner bore of the passive bevel gear 1, tightening the loading claw 3 against the inner bore of the passive spiral bevel gear, accurately positioning the passive spiral bevel gear. A position sensor 5 determines whether the loading claw is clamped in place. The loading base 6, carrying the passive spiral bevel gear 1, enters the photo recognition area for tooth groove identification. Once completed, it enters the loading position, and the pneumatic cylinder is deflated, driving the loading claw 3 to release and wait for the spindle to pick up the material. The spindle rotates according to the photo recognition results to pick up the material. During the picking process, the spindle ball head inserts into the tooth groove, and the universal ball joint reduces frictional resistance during the picking process, effectively preventing the spindle tooling from misaligning the grip. The ball pin easily inserts into the tooth groove for precise positioning, completely resolving the problem of internal bore turning deviation caused by eccentric positioning.

[0026] This new passive spiral bevel gear material channel sliding feeding device has high compatibility, can reduce labor intensity, improve processing efficiency, and reduce material costs. It is highly suitable for the production characteristics of passenger car rear axle spiral bevel gear processing with multiple varieties, small batches, and frequent production changes.

[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, and these should also be regarded as the scope of protection of the present invention.
