Abstract
The utility model relates to a hydraulic tailstock point position control device, which comprises a gearbox body (1), a transmission shaft (5), a hydraulic motor (8), a proximity transducer (6) and a controller. The hydraulic motor (8) and the transmission shaft (5) are mutually connected and positioned through a code wheel (4), the transmission shaft (5) drives a gear shaft (3) through a worm wheel (2) and a worm screw (7), and the gear shaft (3) drives a tailstock through the gearbox body (1). The device has the advantages that the structure is simple, the cost is low, and the control of the tailstock point position is well realized.
Description
Technical field
The utility model belongs to the numerically controlled lathe field of components, particularly relates to a kind of tailstock point level control device.
Background technology
Hydraulic pressure tailstock widespread usage on full function CNC turning machine, but the control aspect is always based on manually, utilize instruction control just on tailstock, to install and to adjust switch, when instruction was carried out, tailstock stopped after moving to the position of the switch, can not advance to the optional position, if want the arbitrfary point Position Control, can only adopt the servo mode of driving, or on tailstock, add a servomotor as axle of digital control system, increase many costs like this with other kind form.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of hydraulic pressure tailstock point level control device, to solve defect of high cost in the prior art.
A kind of hydraulic pressure tailstock point level control device, comprise gearbox body (1), power transmission shaft (5), hydraulic motor (8), proximity transducer (6) and controller, described hydraulic motor (8) links to each other with power transmission shaft (5) and is located by code-disc (4), power transmission shaft (5), by worm gear (2), worm screw (7) gear shaft (3), gear shaft (3) drives tailstock by gearbox body (1).
Beneficial effect
The utility model is simple in structure, and cost is low, has well realized the control of tailstock point position.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A profile of Fig. 1;
Fig. 3 is the tailstock logic diagram of operation automatically.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, 2, a kind of hydraulic pressure tailstock point level control device, comprise gearbox body 1, power transmission shaft 5, proximity transducer 6, hydraulic motor 8 and controller, described hydraulic motor 8 links to each other with power transmission shaft 5 by code-disc 4 location, and power transmission shaft 5 is by worm gear 2, worm screw 7 gear shaft 3, gear shaft 3 drives tailstock by gearbox body 1, thereby realize that tailstock moves, the rotating of hydraulic motor is controlled by reversal valve, and the speed that moves is passed through throttle valve adjustment.
The electrical control hardware aspect is mainly by proximity transducer 6 access controllers, is used for the detection position.In the move of execution tailstock several respects such as amount of movement processing, frequency multiplication, error correction, mobile overproof warning, unexpected recovery are carried out software development.
As shown in Figure 3
When in program, carrying out the tailstock move, controller is at first deciphered displacement, with judging according to direction of advancing and mobile distance whether tailstock satisfies the condition that moves, if exceeding the extreme limit of travel of tailstock, displacement will have warning to send, tailstock is motionless, satisfy the tailstock mobile condition when judgement and send move, tailstock begins to move, this moment is by the detection displacement of feedback, the feedback pulse signal frequency multiplication is segmented, whether tailstock is moved sign indicating number compares consistent with the detection double frequency code, simultaneously the external position error is revised, when error correction finish and tailstock move the sign indicating number with the detection double frequency code equate that controller sends ceases and desist order, tailstock is out of service.If, can under manual mode, return dead-center position owing to reasons such as accident or tailstock warnings.
Claims (1)
1. hydraulic pressure tailstock point level control device, it is characterized in that: comprise gearbox body (1), power transmission shaft (5), hydraulic motor (8), proximity transducer (6) and controller, described hydraulic motor (8) links to each other with power transmission shaft (5) and is located by code-disc (4), power transmission shaft (5), by worm gear (2), worm screw (7) gear shaft (3), gear shaft (3) drives tailstock by gearbox body (1).
