Description

Technical Field

[0001] This utility model relates to a tailstock ejector pin for a roll grinding machine, belonging to the technical field of maintenance equipment for metallurgical roll grinding machines. Background Technology

[0002] As an important component in the rolling of strip, the rolls in metallurgical enterprises need to be ground regularly to ensure rolling quality. Roll grinding machines are used to grind the rolls, and the tailstock center of the roll grinding machine is a key component used for roll positioning. It requires good stability. Due to the large mass of the rolls, the working environment of the roll grinding machine center is relatively harsh. The centers used on site either have poor positioning quality or are frequently damaged, affecting the rolling efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a tailstock center for a roll grinding machine. By utilizing the force generated by spring compression, the grinding roll is positioned, preventing it from moving towards the tailstock end. The rotating shaft and the fixed block are connected by bearings, allowing the center block to rotate with the grinding roll along with the rotating shaft. The magnitude of the spring compression force is determined by an inductive switch that senses the movement of the center block. This achieves the positioning operation of the grinding roll, improves the stability of the center's operation, and solves the aforementioned problems in the background technology.

[0004] The technical solution of this utility model is: a tailstock ejector pin for a roll grinding machine, comprising a center block, a rotating shaft, a fixed block, a spring, and an inductive switch. The center block is fixed on the rotating shaft, the spring is disposed between the center block and the rotating shaft, the rotating shaft is connected to the fixed block through a bearing, the middle part of the fixed block is connected to a lock nut, the inductive switch is fixed on an inductive switch mounting bracket, and the other end of the inductive switch mounting bracket is fixed on the fixed block.

[0005] The top block is made of polyurethane and has four guide holes evenly distributed on it. The top block is fixed to the rotating shaft by four stepped bolts, and the rotating shaft has four bolt holes evenly distributed on it.

[0006] One end of the top block is fixed with a ring by a flat-head screw. The ring is made of steel.

[0007] The bearing has two discs. One end of the fixing block is concave and contacts the outer ring of the bearing. The middle part of the fixing block is threaded and connected to the lock nut through the thread. The other end of the fixing block is tapered.

[0008] The inductive switch is fixed to the inductive switch mounting bracket by a threaded connection. The inductive switch mounting bracket has a threaded through hole. The other end of the inductive switch mounting bracket has two bolt holes, which are used to fix it to the mounting block by bolts.

[0009] The beneficial effects of this utility model are: by using the force generated by spring compression to position the grinding roll, the roll is prevented from moving towards the tailstock end. The rotating shaft and the fixed block are connected by bearings, so that the center block and the rotating shaft can rotate together with the grinding roll. The magnitude of the spring compression force is determined by the inductive switch by sensing the amount of movement of the center block, thereby realizing the positioning operation of the grinding roll and improving the stability of the center operation.

[0013] A tailstock ejector pin for a roll grinding machine includes a center block 1, a rotating shaft 2, a fixed block 3, a spring 7, and a sensor switch 8. The center block 1 is fixed on the rotating shaft 2, the spring 7 is disposed between the center block 1 and the rotating shaft 2, the rotating shaft 2 is connected to the fixed block 3 through a bearing 5, the middle part of the fixed block 3 is connected to a lock nut 4, the sensor switch 8 is fixed on a sensor switch mounting bracket 9, and the other end of the sensor switch mounting bracket 9 is fixed to the fixed block 3.

[0014] The top block 1 is made of polyurethane and has four guide holes evenly distributed on it. The top block 1 is fixed to the rotating shaft 2 by four stepped bolts 6, and the rotating shaft 2 has four bolt holes evenly distributed on it.

[0015] One end of the top block 1 is fixed with a ring 11 by a flat-head screw 12. The ring 11 is made of steel.

[0016] The bearing 5 has two discs. One end of the fixing block 3 is concave and contacts the outer ring of the bearing 5. The middle part of the fixing block 3 is threaded and connected to the lock nut 4 through the thread. The other end of the fixing block 3 is tapered.

The other end of the inductive switch mounting bracket 9 is provided with two bolt holes, which are fixed to the mounting block 3 by bolts 10.

[0018] In practical applications, the center block 1 is made of polyurethane and has four evenly distributed guide holes. The center block 1 is fixed to the rotating shaft 2 by four stepped bolts 6. The spring 7 is located between the center block 1 and the rotating shaft 2. One end of the center block is fixed to a steel ring 11 by a flat-head screw 12. The rotating shaft 2 has four evenly distributed bolt holes and is connected to the fixing block 3 by two bearings 5. One end of the fixing block 3 is concave and contacts the outer ring of the bearing 5; the middle part of the fixing block 3 is threaded and connects to the lock nut 4; the other end of the fixing block 3 is tapered.

[0019] During roll grinding, the conical part of the fixed block 3 is connected to the tailstock of the grinding machine. The movement of the tailstock drives the utility model to move, and the center block 1 contacts the end face of the roll. As the tailstock moves, the center block 1 compresses the spring 7. Guided by the four stepped bolts 6, the center block 1 smoothly compresses the spring 7. When the ring 11 on the center block 1 sends a signal to the inductive switch 8, the tailstock stops moving. The rotating shaft 2 is connected to the fixed block 3 through the bearing 8, allowing the center block 1 and the rotating shaft 2 to rotate together with the grinding roll, achieving stable positioning during rotation. When maintenance is required, the utility model can be ejected by rotating the lock nut 4.
