Description

Technical Field

[0001] This utility model relates to an automated bearing processing equipment, particularly for installing and fixing cages in bearings. Background Technology

[0002] Cylindrical bearings are a common type of rolling bearing, and the way the cylindrical rollers and cage are installed and fixed in the bearing is crucial to the bearing's performance and reliability.

[0003] Short cylindrical rollers are arranged between the outer and inner rings, and these short cylindrical rollers roll between the outer and inner rings. Without setting limiters, the wear of the rollers will increase and the force will be uneven. Setting a cage can reduce vibration and noise.

[0004] The cage consists of a cage body and cage side plates. The cage body has grid strips that create roller grooves on the cage. Short cylindrical rollers are installed in the roller grooves. After the rollers are installed, the cage side plates are placed on the cage body to fix the short cylindrical rollers in the roller grooves on the cage.

[0005] The cage side plates are fixed to the cage side plates by welding. This method provides a more secure fixation, but since the cage has multiple bars, the upper end of each bar needs to be welded to the side plate, making the welding process between the cage and the cage side plates relatively complex. Utility Model Content

[0006] To overcome the shortcomings of the current complex welding process between the cage and the cage side plates, this utility model provides a dual-station welding device for short cylindrical bearing cages.

[0007] The technical solution of this utility model to solve its technical problem is: a dual-station welding equipment for short cylindrical bearing cages, including a feeding device, a transfer device provided on the front side of the feeding device, the transfer device including a first feeding and gripping robot and a second feeding and gripping robot, the first feeding and gripping robot and the second feeding and gripping robot being driven to move by a feeding and gripping robot lateral movement drive unit, the first feeding and gripping robot and the second feeding and gripping robot being driven to open and close by a feeding and gripping robot gripping cylinder; it also includes a first processing table, a first welding device provided on the first processing table, a first clamping block installed on the same side of the first welding device, the first clamping block and the first welding device being fixed on a first pressure table, the first pressure table being driven by a first drive unit to lower and stop the bearing blank on the first processing table; a first rotary drive device is provided below the first processing table, the first rotary drive device including a first rotating component and a first rotary power unit driving the first rotating component, a first drive head provided at the upper end of the first rotating component, a circular hole provided in the middle of the first processing table, the first drive head passing through the circular hole; Similarly, a second processing table, a second drive unit, a second welding device, a second clamping block, and a second rotary drive device are also provided.

[0008] A preferred embodiment of a first driving head is a frustum with a plurality of notches and slots arranged around its circumference. The notches and slots engage with short cylinders, and rotation of the first driving head can cause the cage to rotate by an angle.

[0009] In a preferred embodiment, the first drive unit is a piston cylinder, and the first pressure plate is fixed on the piston end.

[0010] The power unit is preferably selected such that the first rotary power unit is a servo motor, and the servo motor is connected to the first rotating component via a synchronous belt.

[0011] The preferred method for fixing the first drive unit and the second drive unit also includes a support frame, on which the ends of the first drive unit and the second drive unit are fixedly connected.

[0012] The welding device is preferably selected as an argon arc welding device with a welding head.

[0013] The structure of the transfer device is optimized as follows: the first loading clamping robot includes a first loading clamp left arm and a first loading clamp right arm; the second loading clamping robot includes a second loading clamp left arm and a second loading clamp right arm. The first and second loading clamp left arms are slidably mounted on a loading slide rail, and the first and second loading clamp left arms are connected by a left clamp arm connecting rod to form a left clamp arm assembly. The first and second loading clamp right arms are slidably mounted on the loading slide rail, and the first and second loading clamp right arms are connected by a left clamp arm connecting rod to form a left clamp arm assembly. The right and right gripping arms are connected by a right gripping arm linkage to form a right gripping arm assembly. The left gripping arm assembly is connected to a left gripping arm drive block on its outer side, and the right gripping arm assembly is connected to a right gripping arm drive block on its outer side. It also includes a movable block, which is powered to move laterally by the lateral movement drive unit of the loading and gripping robot. The movable block is provided with a clamping guide rail. The right gripping arm drive block is fixedly connected to the movable block. The left gripping arm drive block slides on the clamping guide rail, and the left gripping arm drive block is driven by the gripping cylinder of the loading and gripping robot to move closer to or further away from the right gripping arm drive block.

[0015] In use, the bearing blanks first enter the feeding device. Then, the first and second feeding and gripping robots of the transfer device pick up two bearing blanks and place them on the first and second processing tables. The first drive head of the processing table is inserted into the bearing blank and drives the cage to rotate, thereby enabling the welding table of the welding device to weld one by one, welding the grid strips of the cage to the fixing grooves on the side plates of the cage one by one. After the bearing blanks are welded, the first and second unloading and gripping robots remove the welded bearing blanks from the first and second processing tables.

[0016] The beneficial effects of this utility model are as follows: 1. The automatic loading and unloading and dual-station design reduces reliance on high-intensity manual labor. Loading, unloading, and welding work that originally required multiple heavy-duty workers can now be completed with only a small number of personnel for equipment monitoring and maintenance. This not only reduces labor costs but also reduces the risk of errors and work-related injuries that may result from manual operation, improving production safety and reliability. 2. The automatic welding equipment, with the help of an advanced positioning system and control technology, can accurately position multiple welding points on the short cylindrical bearing cage. During the welding process, it ensures the accuracy and consistency of the welding position, avoiding deviations that may occur during manual welding, ensuring that the quality of each welding point reaches a high standard, thereby improving the overall quality stability of the product. 3. The use of a rotary drive device allows for easy coordination with the rotation of the bearing cylinder to drive the cage rotation, resulting in less wear on the cage and improving the bearing yield.
