Abstract

The utility model discloses a workpiece clamping accuracy detection device for an automatic lathe. The device comprises a probe seat and a rocker arm. The arm body end of the rocker arm is connected with an induction block, and is arranged in the probe seat together with the induction block. An induction coil in touch with the induction block is arranged in the probe seat, and is fixed on a coil seat. A contact and a mandrel fixed on the probe seat are arranged at the swinging end of the rocker arm, so that a structure for reciprocally swinging the rocker arm is formed. The device has the advantages that: workpiece clamping accuracy can be judged, and damaged condition of a workpiece can be timely detected, so that unqualified products in a production process are reduced, and a qualified rate is effectively increased.

Description

The automatic lathe workpiece clamp is held accuracy detecting device

Technical field

The utility model relates to the automatic lathe workpiece clamp and holds accuracy detecting device.

Background technology

In enormous quantities, high-precision rotary class workpiece, adopt the semi-automatic lathe of artificial loading and unloading basically, perhaps utilize the full-automatic lathe processing of manipulator loading and unloading.This type workpiece generally need carry out fine finishining on the processing technology, when rotary work piece secondary clamping carries out fine finishining behind the heat place; General allowance is very little; If this moment, workpiece was because manual work or manipulator are slipped up, and workpiece clamp is held the big circumference of appearance and beated or end face run-out, after lathe starts the processing formula; Because allowance is excessive, will directly cause workpiece to be scrapped even tool damage.If particularly full-automatic lathe is found untimelyly, the damage of cutter will produce in a large number not each lattice article continuously.Yet present automatic lathe does not possess automatic measuring ability basically.

Summary of the invention

The utility model is in order to address the above problem; Provide the automatic lathe workpiece clamp to hold accuracy detecting device, can be through on existing lathe, installing this device additional, before the secondary clamping carries out fine finishining; Device can judge automatically whether clamping workpiece is qualified, thereby whether the control automatic lathe proceeds processing.

In order to achieve the above object; The utility model comprises: probe socket, rocking arm is characterized in that: the arm body termination of rocking arm has sensor block, and is installed in the probe socket together; The induction coil of touching with sensor block is housed in the probe socket, and the swinging end of rocking arm is equipped with contact.

The contact of the utility model is the wolfram steel contact, and can install and remove replacing, and the swinging end of rocking arm is equipped with axle, is used for fixing at probe socket.

The utility model adds workpiece clamp and holds accuracy detecting device on automatic lathe, the judgement that realization is held precision to workpiece clamp, and in time detect the workpiece damaged condition, and too much substandard product appears in the production process thereby reduce, effectively improve qualification rate.

Specific embodiment:

Like Fig. 1, shown in Figure 2; The utility model comprises: probe socket 5, rocking arm 2, probe socket 5 are provided with mounting groove 10 and coil holder groove 11, and coil holder groove 11 is located at probe socket 5 sides; And be stamped cover plate 8 above that; Be embedded with coil holder 7 in the coil holder groove 11, on coil holder 7, be fixed with induction coil 4, probe socket 5 tops are plugged with chock 6.The end of rocking arm 2 arm bodies is equipped with sensor block 3, then rocking arm 2 arm bodies and sensor block 3 is contained in 10 li of the set mounting grooves of probe socket 5 in the lump, sensor block 3 be located at can with the position of induction coil 4 touchings.The swinging end of rocking arm 2 has contact 1 through thread connection, can change through the mounting or dismounting mode, and contact 1 is the Mechanical Contact formula; Can detect that workpiece end face is beated or circle is beated, contact 1 adopts the wolfram steel contact, utilizes its high rigidity; Can effectively prolong the contact life-span, the swinging end of rocking arm 2 is provided with an axle 9, and is fixed on the probe socket 5; Make the rocking arm 2 can reciprocally swinging

As shown in Figure 3, the utility model is installed on the automatic lathe base of tool, and is connected with the displacement conversion circuit with current vortex measuring circuit on the automatic lathe.

The utility model principle:

The wolfram steel contact 1 of this device; Can be with the micro displacement amount; It is last with the distance of induction coil 4 to be reflected at sensor block 3 through rocking arm 2 amplifications, and the variable in distance of sensor block 3 and induction coil 4, with the variation that directly causes induction coil 4 swirl numbers; Through the eddy current measurement circuit, just can measure wolfram steel contact micro displacement amount.When writing the automatic lathe procedure; Artificial perhaps manipulator is after clamping on the chuck is treated accurately machined workpiece well; Start procedure; Lathe chuck drives workpiece and slowly rotates the 2-3 commentaries on classics; Cutter planker that the automatic lathe workpiece clamp holds accuracy detecting device is installed is simultaneously driven the automatic lathe workpiece clamp and hold contact 1 contact workpiece cylindrical or end face outer ring gently in the accuracy detecting device, inductance measurement circuit writes down out the maximum and the minimum of a value of eddy current, and the displacement conversion circuit is converted into respective with swirl number.If difference exceeds setting value, and be regarded as workpiece clamp and hold defectively, automatic lathe no longer carries out next step action, and starts alarm command and report to the police, and reminds the staff to handle.
