Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled roll grinders, and more specifically to a headstock transmission mechanism of a numerically controlled roll grinder. Background Art

[0002] CNC roll grinder is a special equipment using CNC technology, which is used for grinding and repairing rolls. It has the characteristics of high precision, high efficiency and high degree of automation. It is widely used in steel, rolling mill manufacturing and other industries. The equipment accurately controls the grinding process through the CNC system to achieve precise adjustment of the roll diameter, roundness and surface quality, thereby ensuring the normal operation and stability of the roll. The CNC roll grinder can grind the roll body, roll neck and other parts, effectively improving the service life and performance of the roll.

[0003] The headstock is mainly used to support and drive the roller to rotate so that the grinding head can grind it. It is an important basis for realizing the precision machining of the roller and directly affects the machining accuracy and efficiency.

[0004] In addition, during the existing headstock driving process, when cutting or grinding needs to stop, it will still work for a period of time due to the operation of the motor or the action of inertia, thereby affecting the processing accuracy. Therefore, a headstock transmission mechanism for a CNC roll grinder is proposed. Utility Model Content

[0005] In order to overcome the above defects of the prior art, the utility model provides a headstock transmission mechanism of a numerically controlled roll grinder to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a CNC roller grinder headstock transmission mechanism, comprising a bed body, a frame body installed at one end of the bed body, a hydraulic pump installed at one end of the frame body, the hydraulic pump is connected to a hydraulic rod, one end of the hydraulic rod is rotatably connected to a second shaft connection, the second shaft connection is connected to a transmission assembly, one side of the transmission assembly is meshedly connected to a drive assembly, a first shaft connection is installed at the other end of the frame body, the first shaft connection is rotatably connected to a turntable, and locking assemblies are arranged on both sides of the frame body.

[0007] Preferably, the driving assembly comprises a driving motor, a driving rod and a driving gear. The driving motor is mounted on a frame, an output end of the driving motor is connected to the driving rod, and a driving gear is coaxially mounted on the end of the driving rod.

[0008] Preferably, the transmission assembly includes a shaft rod, a follower gear and a plug. The shaft rod is inserted into the frame body. A follower gear meshing with the driving gear is coaxially arranged at one end of the shaft rod. The thickness of the driving gear is greater than that of the follower gear. A plug is arranged at the other end of the shaft rod.

[0009] Preferably, a regular hexagonal slot is provided on one side of the turntable, and the plug is plugged into the slot.

[0010] Preferably, the locking assembly comprises an electric push rod and a locking plate, and the locking plate is installed at the telescopic end of the electric push rod.

[0011] Preferably, a tooth groove is provided in an annular shape on the rotating disk, and a plurality of teeth are provided on the locking plate, and the teeth are meshed with the tooth groove.

[0012] Technical effects and advantages of the utility model:

[0013] 1. The driving motor is driven to rotate the driving rod, so that the driving gear rotates accordingly. The shaft rod rotates accordingly through the meshing connection with the follower gear. When the plug is ejected by the hydraulic rod and connected with the slot, the turntable can work accordingly. The contraction of the hydraulic rod can also pull the plug out of the slot, so as to control the connection and disconnection of the turntable and the transmission assembly.

[0014] 2. By extending the electric push rod, the locking plate is brought closer to the turntable, so that the locking plate abuts against the turntable, thereby directly locking and stopping the inertial rotation of the turntable, avoiding continuous inertial rotation of the turntable, thereby improving the grinding accuracy.

[0022] As attached Figure 1-5 The headstock transmission mechanism of a CNC roller grinder shown in the figure includes a bed body 1, a frame body 2 is installed at one end of the bed body 1, a hydraulic pump 3 is installed at one end of the frame body 2, the hydraulic pump 3 is connected to a hydraulic rod 9, one end of the hydraulic rod 9 is rotatably connected to a second shaft connection 10, the second shaft connection 10 is connected to a transmission component 4, one side of the transmission component 4 is meshedly connected to a drive component 5, a first shaft connection 8 is installed at the other end of the frame body 2, the first shaft connection 8 is rotatably connected to a turntable 6, and locking components 7 are arranged on both sides of the frame body 2.

[0023] During specific implementation, the hydraulic pump 3 is operated to extend the hydraulic rod 9, thereby pushing the transmission component 4, so that one end of the transmission component 4 is inserted into the turntable 6, and when the drive component 5 is running, it can engage the transmission component 4 to rotate, so that the turntable 6 rotates, thereby performing the grinding work. When the work stops, that is, when the drive component 5 stops running, the hydraulic rod 9 retracts, so that the transmission component 4 is reset and the connection with the turntable 6 is disconnected. At the same time, the ends of the locking components 7 on both sides are extended and abut against the turntable 6, so that the rotation of the turntable 6 stops immediately, so that the grinding can be controlled more accurately and the grinding accuracy is improved.

[0024] The driving assembly 5 includes a driving motor 501, a driving rod 502 and a driving gear 503. The driving motor 501 is installed on the frame 2.

[0026] A regular hexagonal slot is provided on one side of the turntable 6, and the plug 403 is plugged into the slot.

[0027] During specific implementation, the driving motor 501 is driven to rotate the driving rod 502, thereby causing the driving gear 503 to rotate accordingly. The shaft rod 401 is rotated by meshing connection with the follower gear 402. When the plug 403 is ejected by the hydraulic rod 9 and connected to the slot, the turntable 6 can work accordingly. The contraction of the hydraulic rod 9 can also remove the plug 403 from the slot, thereby controlling the connection and disconnection of the turntable 6 and the transmission assembly 4.
