Embodiment 1
[0026] A new type of bearing ring external expansion type overall fixture, including a transition plate 1, a support plate 2, a positioning table 3, a push rod 4, a chuck 5, and a moving table 6. The transition plate 1 is provided with a mounting hole 7, and the transition plate 1 A set of support plates 2 are arranged correspondingly on the side, and a positioning platform 3 is fixedly connected to the other side of a set of support plates 2. The function is to realize the positioning of the bearing. The bottom side of the positioning table 3 is provided with a chute 8, and the chute 8 is provided with a slider 9. The slider 9 is slidably connected with the chute 8, and one side of the slider 9 is fixedly connected. Collet 5, chute 8, slider 9, and collet 5 cooperate with each other to realize that chuck 5 slides in chute 8 through slider 9. Anti-slip pads are arranged on chuck 5, and chuck 5 Arranged in an arc and the arc matches the arc of the inner wall of the bearing, the...
Embodiment 2
[0030] In the present invention, the collet 5 and the slider 9 are fixedly connected by screws, the screw fixing structure has a stable fixing effect, and is convenient for disassembly, and the mounting hole 7 is a screw through hole, which is convenient for installation;
[0031] The positioning platform 3 is adhesively connected with a protective pad, which can protect the bearing, and the support plate 2 is fixedly connected with the transition plate 1, which can increase the stability;
[0032] The driving head of the push rod 4 is fixedly connected with the lower surface of the mobile platform 6 by bolts, and the mobile platform 6 can be conveniently disassembled and replaced by the bolts;
[0033] The moving block 10 and the bottom of the chuck 5 are fixedly connected by bolts, which can facilitate the maintenance of the chuck 5;
[0034] The mobile block 10 is matched with the mobile station 6 to ensure normal operation;
[0035] The ball 11 is slidingly connected to t...
Embodiment 3
[0040] see Figure 1-2, the working principle of the present invention is that when in use, the push rod 4 is connected to the piston rod of the machine tool through the connecting hole on the push rod 4, and then the transition plate 1 and the machine tool are connected by bolts through the mounting hole 7 to complete the clamping, and then the The bearing to be processed is placed on the positioning table 3, and then the piston rod of the machine tool is controlled to push forward, thereby driving the push rod 4 to move forward. Because the pushing head of the push rod 4 is fixedly connected with the mobile table 6, the mobile table 6 will also Move forward, and because the mobile platform 6 is arranged in a quadrangular platform structure, and the corresponding side of the mobile platform 6 is in contact with the mobile block 10, the bottom of the mobile block 10 is also provided with a ball 11, and the top is also provided with a chuck 5, and the collet 5 is fixedly connec...

Abstract
The invention discloses a novel bearing ring external expansion type integral clamp. A mounting hole is formed in a transition plate, a set of supporting plates are correspondingly arranged on the side surface of the transition plate, positioning tables are fixedly connected to the other sides of the set of supporting plates, the positioning tables and the supporting plates are arranged in an L-shaped structure, sliding grooves are formed in the side surfaces of the bottoms of the positioning tables, sliding blocks are arranged in the sliding grooves, clamping heads are fixedly connected to one sides of the sliding blocks, the clamping heads are arranged in an arc shape, the radian of the clamping heads is matched with the radian of the inner wall of a bearing, the bottoms of the clampingheads are fixedly connected with moving blocks, an opening is formed in the transition plate, a push rod penetrates through the opening and is arranged between the set of supporting plates, a push head of the push rod is fixedly connected with the lower bottom surface of a movable table, the bottoms of the moving blocks are arranged in an inclined structure, the inclined angle is matched with theinclined angle of the side surface of the movable table, balls are arranged at the bottoms of the moving blocks, and the balls make fit contact with the side face of the movable table. The novel bearing ring external expansion type integral clamp has the beneficial effects of being simple in structure, convenient to debug and short in clamping time, and is mainly used for fixing the bearing.
Description
technical field [0001] The invention belongs to the technical field of bearing processing, and in particular relates to a new type of externally expanding overall clamp for bearing rings. Background technique [0002] Bearing ring (bearing ring) is a ring-shaped part of a radial rolling bearing with one or several raceways. Its production steps are forging. Reduce the toughness and strength of the ferrule, so the processing temperature, cycle heating and heat dissipation conditions after forging (such as spray cooling) must be strictly controlled all the time. Stacking and placement; heat treatment, close monitoring of heat treatment equipment is an important task in the workshop, the reliability of monitoring equipment, and important temperature control devices such as instruments and thermocouples must be closely monitored to ensure that the measurement data is accurate and reliable; if the error exceeds the standard, it must be timely Replacement, it is strictly forbidde...
