Abstract
A turning clamping fixture for a forklift front wheel spindle support comprises a round four-jaw chuck base, four pressure plates, two trapezoidal limiting blocks and two trapezoidal abutting-against blocks. The trapezoidal limiting blocks are arranged at the positions of semicircle holes in the outer sides of two 45-degree end faces of a forklift front wheel spindle support semicircle, and side walls of the two trapezoidal limiting blocks contacted with the semicircle holes and the 45-degree end faces are on the same plane. The four pressure plates are respectively provided with a supporting rod and a bolt adjusting hole, bolts for tightening pressure blocks and workpieces are arranged in the bolt adjusting holes, and the two trapezoidal abutting-against blocks are provided with abutting-against screws up and down to be used for abutting against side walls of the workpieces. After the workpieces are fixed, the four-jaw chuck base is entirely installed on a lathe spindle, inner circles begin to be processed, and the processed inner circles are extremely smooth. Besides, two or more workpieces can continue being stacked above two workpieces, and the inner circles are processed simultaneously.
Description
Technical field
The present invention relates to a kind of machining mould, relate in particular to a kind of machining mould that is suitable for the turning inner circle.
Background technology
All there is a support fork truck front-wheel main shaft both sides, and the semi-circular structure on support is fastened on main shaft, plays a supporting role.In process, especially half circular surfaces turning adds man-hour, normally single processing, and efficiency is lower.And double circular surfaces processing, during turning, lathe tool need to be walked the idle running of a semicircle, and, at processing half bowlder, due to the hardness of labor cost, causes lathe tool not cause the workpiece of turning can not reach required precision according to circular trace work completely, sufficiently oily.
Summary of the invention
For adapting to the processing of fork truck front-wheel spindle carrier, improve machining accuracy and quality, the turning machining mould of the special fork truck front-wheel spindle carrier of making of the present invention, not only identical two workpiece can be combined, two semicircles are combined into a circle and process simultaneously, and stack fork truck front-wheel spindle carrier turning simultaneously inner circle is continued in these two workpiece tops again, plays a multiplier effect.
Technical scheme of the present invention is:
This mold comprises that circular four grab chuck base, four pressing plates, two trapezoidal limited blocks, two trapezoidal withstanding tight blocks, trapezoidal limited block is arranged on the semicircle orifice place, two 45 ° of end faces outside of fork truck front-wheel spindle carrier semicircle, and the sidewall that two trapezoidal limited blocks contact with semicircle orifice and 45 ° of end faces are in one plane.Four pressing plates arrange respectively a support bar and a bolt adjustment hole, in the bolt adjustment hole, arrange in order to tighten the bolt of briquetting and workpiece; Two trapezoidal withstanding tight blocks all arrange and hold out against the sidewall of screw in order to top tight workpiece up and down.
After workpiece is fixing, four grab the chuck base integral installation on lathe spindle, start to process inner circle, and the inner circle processed is very level and smooth.
And, can also continue two or more workpiece that superpose above two workpiece, process inner circle simultaneously.Due to the trapezium structure of trapezoidal limited block and trapezoidal withstanding tight block, workpiece is 2 or 4 processing simultaneously.
Beneficial effect of the present invention is: can disposable processing two or four workpiece, and compare efficiency is provided with single workpiece processing.Also solved single workpiece and added the not round and smooth problem of semicircle in man-hour simultaneously.
The accompanying drawing explanation
The present invention has accompanying drawing 1 width.
Fig. 1 is principle of the invention figure.
Sequence number explanation in figure, 1. four grab chuck base, 2. pressing plate, 3. trapezoidal limited block, 4. trapezoidal withstanding tight block, 5. semicircle orifice, 6, solder side.
The specific embodiment
Below in conjunction with specific embodiment explanation the present invention,
Turning machining mould as the fork truck front-wheel spindle carrier of Fig. 1 the present embodiment, comprise that circular four grab chuck base 1, the trapezoidal limited block of four pressing plates 2, two 3, two trapezoidal withstanding tight blocks 4, trapezoidal limited block 3 is arranged on semicircle orifice 5 places, two 45 ° of end faces outside of fork truck front-wheel spindle carrier semicircle, and the sidewall that two trapezoidal limited blocks 3 contact with semicircle orifice 5 and 45 ° of end faces are in one plane.Four pressing plates 2 arrange respectively a support bar and a bolt adjustment hole, in the bolt adjustment hole, arrange in order to tighten the bolt of briquetting 2 and workpiece; Two trapezoidal withstanding tight blocks 4 all arrange and hold out against the sidewall of screw in order to top tight workpiece up and down.
After workpiece is fixing, four grab chuck base 1 integral installation on lathe spindle, start to process inner circle, and the inner circle processed is very level and smooth.
And, can also continue two or more workpiece that superpose above two workpiece, process inner circle simultaneously.
Process the early stage of workpiece workpiece before this step processing as follows, at first steel plate cut into to the single fork truck front-wheel spindle carrier blank with semi-circular structure; The semicircle two ends of fork truck front-wheel spindle carrier are 45 ° of end faces, wherein an end also arranges to go here and there and inserts bolt in order to be fixed on the semicircle orifice on the fork truck main shaft, the shape of workpiece as shown in Figure 1, wherein 45 ° of end faces refer to this end face and solder side 6 at 45 °, and solder side 6 is welded on fork truck when mounted.45 ° of end faces and other end face, by after the milling machine completion of processing, are put into two workpiece on this mold simultaneously, carried out turning processing.45 ° of end face corresponding contact of two workpiece, the semicircle of two fork truck front-wheel spindle carriers is combined into a circle.
