Abstract

The utility model relates to an improved CA6140 serial lathe headstock, which is composed of a motor M, a belt, a belt wheel, a shaft (1), a shaft (2), a shaft (3), a shaft (4), a shaft (5), a shaft (6) and gears arranged on the shafts. When a main shaft of the utility model drives at 6 grade high speed, a gear (1) of the shaft (3) is engaged with a gear (2) of the shaft (4), and the ratio of tooth number thereof is 1: 4. Meanwhile, a dual gear (9) of the shaft (4) is positioned in the vacancy between two fixed gears (10), (11) of the shaft (5). Because of such improvement, the noise, vibration and power consumption are decreased. The utility model has the advantages of enhancement of workpiece quality and dynamic performance of the lathe, simple retrofit work and low cost, and is favorable to the physical and mental health of workers.

Description

CA6140 serial lathe headstock

The utility model relates to a kind of improved CA6140 series spindle stock.

CA series lathe is a kind of universal machine tools, this lathe is very wide in China's scope of application, be that each machining factory owner wants one of equipment, but it is exactly when 6 grades of transmissions of main shaft high speed that this lathe exists a big shortcoming, the rotation of motor M is passed to main shaft (axle VI) through axle (I), axle (II), axle (III), and main shaft is rotated at a high speed.But axle this moment (IV) participates in rotating with axle (V) too, makes these two axles with the same slightly high rotating speed idle running of axle (III), thereby has strengthened noise, has increased vibration source, has also increased power consumption.

The utility model is the improvement to CA series spindle stock, makes this lathe when 6 grades of transmissions of high speed, axle (IV) is in rotates under the low velocity very much, and axle (V) is not rotated, thereby reach the purpose that reduces noise, vibration and power consumption.

The purpose of this utility model is achieved in that

By motor M, belt, belt pulley, axle (I), axle (II), axle (III), axle (IV), axle (V), axle (VI) and on the headstock that constitutes of gear in, make lathe when 6 grades of transmissions at a high speed the gear (2) on the gear (1) on the axle (III) and the axle (IV) with the gear ratio engagement of 1:4; The duplicate gear (9) of axle on (IV) is between the room of fixed gear (10) on the axle (V) and (11).

With the method that the utility model provides CA series spindle stock is transformed, can reduce greatly because lathe idler gear and noise that produces when main shaft rotates at a high speed, and reduce vibration, thereby help workman's physical and mental health and improve the workpiece crudy, also help prolonging the service life of lathe, reduce owing to no-load power again, also with regard to energy savings, and the method for transforming is also simple and easy to do, so improvement cost is very low.

Further introduce the utility model below by accompanying drawing

Fig. 1 is the former kinematic scheme of CA6140 series spindle stock

Fig. 2 is the utility model kinematic scheme

From accompanying drawing 1, can see the original system figure of CA series spindle stock when high-speed drive. Motor M passes to axle (I) to power through one group of belt, a pair of belt pulley, axle (I) is by a duplex gear driven axle (II), axle (II) is by triple gear band moving axis (III), axle (III) is with the gear (6) on gear (5) the drive main shaft (axle III), because the number of teeth of gear (5) is more than the number of teeth of gear (6), therefore be the raising speed transmission from axle (III) to axle (IV), become 6 grades of high speeds. Meanwhile, the gear (3) that is fixed on the axle (III) also is meshed with gear (4) on the axle (IV), because gear (3) equates with gear (4) number of teeth, so makes axle (IV) and axle (III) with synchronized rotation; When axle (IV) rotated, the gear (9) that is fixed on the axle (IV) drove again gear (10) rotation that is meshed with it, and gear (10) is solid Fix on the axle (V), so axle (V) idle running, from accompanying drawing 1, can see, also be fixed with gear (7) on the axle (V) and it is meshed with the gear (8) of empty set on main shaft (VI), so gear (8) is in idle running. From accompanying drawing 2, can see, actuated element of the present utility model and former transmission system are just the same, but the gear (2) of the utility model on gear (1) the band moving axis (IV) that is fixed on above the axle (III), and the gear ratio of gear (1) and gear (2) is 1:4, therefore be the reduction of speed transmission, just make axle (IV) with 1/4th rotational speed of axle (III). Meanwhile, double crosslinking sliding gear (9) on the axle (IV) is placed between two fixed gears (10) on the axle (V), (11), they are not meshed mutually, thereby do not carry out transmission, therefore axle (IV) just can not be with moving axis (V) fast idle, can not drive gear (8) idle running on the main shaft (VI).

Embodiment:

When CA6140 spindle stock main shaft rotated with 1400 rev/mins, former (IV) axle rotating speed was 1120 rev/mins, and the transmission system that the utility model provides to make axle (IV) be 280 rev/mins; Primitive axis (V) rotating speed is 1142 rev/mins, is zero in the utility model; The rotating speed that former main shaft (VI axle) is gone up free gear (8) is 512 rev/mins, and the utility model is zero, and the utility model makes this lathe high speed 6 grades tangible noise reduction vibration damping, energy-conserving action be arranged all.Maximum noise reduction reaches 3dB(A) more than, half promptly reduced; Maximum vibration damping amount is 50%, and maximum no-load power reduces 25%.

Claims

1, a kind of CA6140 series spindle stock, be by motor (M), belt, belt pulley, axle (I), axle (II), axle (III), axle (IV), axle (V), axle (VI) and the gear on each constitute, it is characterized by: when 6 grades of transmissions of main shaft high speed, gear (2) engagement on gear (I) on the axle (III) and the axle (IV), its gear ratio is 1: 4; The duplicate gear (9) of axle on (IV) is between two fixed gears (10) and (11) room on the axle (V).
