Abstract
The utility model provides a slow -witted anchor clamps are prevented to bent axle spring spot facing work belongs to machining anchor clamps technical field, including anchor clamps main part, pushing cylinder, collet, pull rod, mistake proofing round pin, the anchor clamps main part is the tube -shape holder, install pushing cylinder, collet, pull rod, mistake proofing round pin by the skin in proper order to the inlayer in the anchor clamps main part. The utility model discloses a slow -witted anchor clamps are prevented to bent axle spring spot facing work has stopped to flow in the back process because of the undressed work piece in spring hole, in addition, effectively improve clamping efficiency, avoid simultaneously leading to the work piece to be damaged because of the clamping is inconvenient.
Description
Technical field
The utility model relates to a kind of clamping tool for machine work technical field, particularly relates to bent axle spring eye processing foolproof fixture.
Background technology
At present, in the Crankshaft Machining process of compressor of air conditioner, a procedure is had to adopt fixture internal keyway locate mode, bent axle for compressor of air conditioner has a spring eye, in process, often occur that the situation of leaking processing is not easily discovered, flow directly into subsequent processing, the quality of Crankshaft Machining is difficult to ensure.
Utility model content
In view of the above, be necessary to provide a kind of and can improve processing quality, locate good bent axle spring eye processing foolproof fixture.
A kind of bent axle spring eye processing foolproof fixture, comprise jig main body, pushing cylinder, collet, pull bar, mistake proofing pin, described jig main body is tubular holder, installs pushing cylinder, collet, pull bar, mistake proofing pin from the outer to the inner successively in described jig main body.
Further, comprise work locating piece, described work locating piece is arranged on jig main body one end.
Further, one end that described jig main body is connected with work locating piece offers positioning spiro pit, also offers the screwed hole through with inner chamber in the middle part of described jig main body.
Further, described collet body comprises an anchor portion, fixing neck and fixing head, is provided with the clamping hole of holding workpiece in body.
Further, described pull bar is cylindric, and comprise the connecting portion fixedly welded with the anchor portion of described collet, described push-and-pull portion offers two installation screws.
Compared to prior art, bent axle spring eye processing foolproof fixture of the present utility model, has stopped because spring eye unprocessed workpiece flows into rear operation; In addition, effectively improve clamping efficiency, avoid because clamping inconvenience causes workpiece to be damaged simultaneously.
Accompanying drawing explanation
Fig. 1 is the assembly drawing of bent axle spring eye of the present utility model processing foolproof fixture clamping bent axle;
Fig. 2 is the collet structure chart shown in Fig. 1;
Fig. 3 is the Tiebar structure figure shown in Fig. 1.
Detailed description of the invention
By describing technology contents of the present utility model, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
Refer to Fig. 1, bent axle spring eye processing foolproof fixture 100 of the present utility model, for clamping workpiece, be described in the present embodiment for clamping bent axle 200, it comprises jig main body 10, pushing cylinder 20, collet 30, pull bar 40, mistake proofing pin 50 and work locating piece 60.Described jig main body 10 is tubular holder, and install pushing cylinder 20, collet 30, pull bar 40, mistake proofing pin 50 successively from the outer to the inner in jig main body 10, described work locating piece 60 is arranged on jig main body 10 one end.
One end that described jig main body 10 is connected with work locating piece 60 offers positioning spiro pit.The screwed hole through with inner chamber is also offered in the middle part of described jig main body 10.
Described pushing cylinder 20 is set in outside collet 30, pull bar 40, coordinates to clamp, unclamp workpiece with collet 30.
Refer to Fig. 2, described collet 30 body comprises an anchor portion 31, fixing neck 32 and fixing head 33, is provided with the clamping hole 34 of holding workpiece in body, and described fixing head 33 is middle fusiformis of expanding.
Refer to Fig. 3, described pull bar 40 is cylindric, comprises the connecting portion 41 and push-and-pull portion 42 that fixedly weld with the anchor portion 31 of described collet 30.Described push-and-pull portion 42 offers two installation screws 421.During installation, described pull bar 40 axis and described collet 30 dead in line.
Described mistake proofing pin 50 is multidiameter, and large footpath section diameter is suitable with described pull bar 40 internal diameter, and path section diameter is less than bent axle 200 spring eye aperture.
When using bent axle spring eye of the present utility model to process foolproof fixture 100, when clamping bent axle 200, if workpiece is inserted not enter when leaking spring eye, locate bad, stopped because spring eye unprocessed workpiece flows into rear operation; In addition, change locate mode, located by original fixture internal keyway and change to additional eccentric positioning tool, effectively improve clamping efficiency, avoid because clamping inconvenience causes workpiece to be damaged simultaneously.
Bent axle spring eye processing foolproof fixture 100 of the present utility model is outside the high accuracy advantage retaining collet-type clamping, increase fool proof mobile type alignment pin, collet-type clamp method, do not increase other and any influence factor of clamping is operated to employee, avoid mistake proofing pin and directly to contact with workpiece and the workpiece produced is damaged.Workpiece is loaded in collet chuck, mistake proofing pin can accurate centering spindle end centre bore, workpiece can easily touch locating and machining datum level, any interference is not produced to process, effectively avoid spring eye leakage to process the workpiece caused to scrap and collision accident generation, operation after simultaneously avoiding the workpiece in Lou processed springs hole to flow into, significantly heightens clamping efficiency, reduces quality fraction defective.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure transformation utilizing the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
