Description
Technical field
The invention discloses a kind of bearing ring turning digital control lathe, belong to the bearing ring turning digital control lathe technical field with automatic on-line air pressure detection function.
Background technology
After existing bearing lasso turning digital control lathe is opened, the loading machine parts can be automatically clamping workpiece to claw, workpiece processing beginning.In actual applications, existing bearing lasso turning digital control lathe exists time rate height, the serious problem of waste of material.Tracing it to its cause, mainly is following 2 points:
1. workpiece for various reasons, has the situation that clamping is not in place, clamping is not positive unavoidably in process;
2. it is bad that impurity such as iron filings, dust also can cause the clamping position of workpiece.
And clamping workpiece is not in place or clamping position is bad, can cause that all the workpiece of processing is scrapped, thereby improve defect rate.
Summary of the invention
In order to address the above problem, the invention provides a kind of time low bearing ring turning digital control lathe of rate that goes out with automatic on-line air pressure detection function.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of bearing ring turning digital control lathe with automatic on-line air pressure detection function, comprise and be installed in the main spindle box and leading section is positioned at the outer main shaft of main spindle box, the outer wall of this leading section is equipped with axle bush from inside to outside successively, drive end bearing bracket, terminal pad is installed on the front bulkhead of leading section successively, the hollow terminal pad, the hollow brake, claw, described drive end bearing bracket, axle bush, leading section, terminal pad, the hollow terminal pad, offer the gas circuit that connects on the hollow brake successively, wherein offering an end on the drive end bearing bracket is connected with the external pressure on-line measuring device, the air inlet that the other end is connected with gas circuit offers the gas leakage that is connected with gas circuit and detects the hole on the front bulkhead of hollow brake; The air pressure on-line measuring device is connected with the Programmable Logic Controller of control main shaft.
Described claw is installed in the front end of hollow brake by chuck, resilient sleeve.
Described gas leakage detects Kong Yousan, and is uniformly distributed in circumference on the front bulkhead of hollow brake.
The present invention effectively combines air pressure on-line measuring device, Programmable Logic Controller, gas circuit, when workpiece not just clamping do not occurring, or workpiece phenomenon such as occur skidding during turning, the air pressure on-line measuring device will detect the abnormal air-pressure signal immediately by gas circuit, then this abnormal air-pressure signal is sent to Programmable Logic Controller at once, after Programmable Logic Controller receives the abnormal air-pressure signal, can stop processing to bearing ring turning digital control lathe immediately handles, after treating that clamping workpiece is correct, restart again.Thus, just greatly reduce out time rate, thereby reduced the waste of material, reduced production cost.
The invention will be further described below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As schematically shown in Figure 1, the present invention has the bearing ring turning digital control lathe of automatic on-line air pressure detection function, comprise and be installed in the main spindle box 15 and leading section 3 is positioned at the outer main shaft 1 of main spindle box 15, the outer wall of this leading section 3 is equipped with axle bush 13, drive end bearing bracket 2 from inside to outside successively, terminal pad 4, hollow terminal pad 5, hollow brake 10, claw 7 are installed on the front bulkhead of leading section 3 successively, and this is the common structure of existing bearing ring turning digital control lathe.
The improvement of this case is: offer the gas circuit 12 that connects on drive end bearing bracket 2, axle bush 13, leading section 3, terminal pad 4, hollow terminal pad 5, the hollow brake 10 successively, wherein offer the air inlet 14 that an end is connected with external pressure on-line measuring device 16, the other end is connected with gas circuit 12 on the drive end bearing bracket 2, offer the gas leakage that is connected with gas circuit 12 on the front bulkhead of hollow brake 10 and detect hole 9; Air pressure on-line measuring device 16 is connected with the Programmable Logic Controller 17 of control main shaft 1.
As the further setting of the present invention, claw 7 is installed in the front end of hollow brake 10 by chuck 6, resilient sleeve 11.
Further be provided with as of the present invention, gas leakage detects hole 9 three, and is uniformly distributed in circumference on the front bulkhead of hollow brake 10 again.
Operation principle of the present invention is as follows:
Before formal production, earlier with the standard component clamping in claw 7, and guarantee that standard component detects hole 9 with three gas leakage and all stops up, open air pressure on-line measuring device 16 again, gas is entered by air inlet 14, detect hole 9 by the gas leakage on gas circuit 12 back arrival hollow brakes 10 front bulkheads of each perforation, air pressure on-line measuring device 16 will detect the air pressure under the normal condition at this moment, a button is arranged on air pressure on-line measuring device 16, press back air pressure on-line measuring device 16 and the normal barometric pressure signal will be transferred to Programmable Logic Controller 17, Programmable Logic Controller 17 is just remembered this normal barometric pressure.It more than is normobaric setting.Next, carry out the formal processing of workpiece 8.Aborning, if there are workpiece 8 clampings not in place or clamping position is bad, gas leakage detects hole 9 and will leak gas, operating air pressure in the gas circuit 12 will be lower than setting air pressure so, behind the abnormal air-pressure signal of air pressure on-line measuring device 16 in detecting gas circuit 12, immediately this abnormal air-pressure signal is transferred to Programmable Logic Controller 17, behind the different abnormal air-pressure signal of normal barometric pressure that Programmable Logic Controller 17 sets before receiving and formally producing, can stop processing to bearing ring turning digital control lathe immediately handles, after treating that workpiece 8 clampings are correct, restart again.
Need to prove that in formal process, air pressure on-line measuring device 16 only after receiving the signal of workpiece 8 clampings in the claw 7, is just started working.
Airflow route of the present invention is: air inlet 14 → drive end bearing bracket 2 → axle bush 13 → leading section 3 → terminal pad 4 → hollow terminal pad 5 → hollow brake 10 → gas leakage detects hole 9.
In a word, defect rate of the present invention is low, waste of material is few, production cost is low.
The foregoing description only is used to the inventive concept of the present invention of explaining, but not to the qualification of rights protection of the present invention, allly utilizes this design that the present invention is carried out the change of unsubstantiality, all should fall into protection scope of the present invention.
