Abstract
The utility model relates to a problem for machining a thin-wall metal welded part in mechanical industry, and particular to an end surface milling clamp for a medium box supporting frame, which is developed for aiming at defects such as easy deformation in machining process of the medium box supporting frame that is an important component in a high-gradient magnetic separator. The end surface milling clamp comprises a movable board of which one side is arc-shaped. Simultaneously the movable board can rotate around a pin. A positioning pin is fixed on a fixing jaw through a nut. A floating pressure board is connected with a movable jaw through the pin. The movable jaw can move in a jaw guiding board which is welded on a clamp base board. A lead screw nut is fixed on the clamp base board through a screw. One end of a trapezidal lead screw is provided with a through hole on which a rotatable handle can be arranged. The end surface milling clamp provided by the utility model can effectively reduce deformation of a thin-wall workpiece in machining and improves qualified rate of machining.
Description
Technical field
The utility model relates to the machining tool clamp field, refers in particular to the processing of the processing that is suitable for vertical ring high-gradient magnetic separator cartridge bracing frame and other machinery industry thin-wall metal weldment.
Background technology
Vertical ring high-gradient magnetic separator is the necessary equipment of current Mineral Processing Industry, in critical component change wherein, a large amount of cartridges is installed, it is to install by being welded on bracing frame between change two flange faces, because bracing frame is the thin walled welds part, welding deformation in various degree occurs between both ends of the surface and installed surface, therefore, both ends of the surface must be processed, make it vertical with installed surface, guarantee All Media box is in place, in the past during the process support frame, bracing frame directly is clipped on general flat-nose pliers, because workpiece is thin-wall part, must manually backing plate be placed between bracing frame and jaw, experience by the operator guarantee with the workpiece locating surface between parallel, therefore, production efficiency is low, difficult quality guarantee.
Summary of the invention
The utility model is for the problem existed in background technology, become a side that the rotatable pressing plate of arc is arranged common flat mouth platen design, forwardly be welded with two briquettings with deep-slotted chip breaker simultaneously, become 2 contacts by the line contact while making jaw compress, reduced the jig jaw clamping force skewness that workpiece deformation causes, the workpiece deformation caused after clamp reduces, thereby making to process the error of perpendicularity between the both ends of the surface of rear workpiece and installed surface reduces, improved the workpiece crudy, reduced workman's labour intensity, clamped one time puts in place, do not need repeatedly to adjust, technical merit to the operator requires lower, improved labor productivity, after using this fixture, working (machining) efficiency before being more than three times, improved product quality, the original product qualification rate is 75%, and after using this fixture, product percent of pass is more than 98%.
The technical solution of the utility model refers to the fixture that comprises following structure:
Portable plate one side band arc, can rotate around bearing pin simultaneously, wherein regular jaw is welded on clamp bottom board, shop bolt is fixed on regular jaw by nut, the floating platen be equipped with the deep-slotted chip breaker briquetting links by bearing pin and moving jaw, split pin is housed on bearing pin, prevent that bearing pin from deviating from, moving jaw can move in the jaw guide plate, the jaw guide plate is welded on clamp bottom board, trapezoidal screw links by screw mandrel gland and moving jaw, trapezoidal screw and feed screw nut screw, the feed screw nut is fixed by screws on clamp bottom board, on trapezoidal screw, an end has through hole, the above's rotary handle of can packing into.
The accompanying drawing explanation
Fig. 1 is the utility model Fixture assembly front view.
Fig. 2 is the utility model Fixture assembly top view.
the specific embodiment:
Embodiment is described in further detail structure of the present utility model and operation principle by reference to the accompanying drawings.
In figure mono-, figure bis-, critical piece has: shop bolt (1), regular jaw (2), bracing frame body (3), clamp bottom board (4), bearing pin (5), split pin (6), moving jaw (7), screw mandrel gland (8), trapezoidal screw (9), floating platen (10), jaw guide pad (11), feed screw nut (12).
Operation principle of the present utility model: bracing frame body (3) is arranged on milling machine table by the kidney slot on base plate, during clamping, at first utilize two through holes made on workpiece to be arranged on two shop bolts (1) of regular jaw (2), then rotate trapezoidal screw (9) by handle, the moving jaw (7) linked with trapezoidal screw (9) is moved in the middle of two jaw guide pads (11), the floating platen (10) linked by bearing pin (5) and moving jaw (7) moves thereupon, while clockwise rotating handle, floating platen (10) is to workpiece one side shifting, on it, the briquetting with deep-slotted chip breaker of welding is stuck on workpiece, because floating platen (10) can rotate around bearing pin (5), thereby can guarantee that workpiece is clamped rear stressed even, be out of shape little, again after face cutter milling both ends of the surface, can guarantee that the perpendicularity of both ends of the surface and installed surface is in error range, after completion of processing, the counterclockwise rotation fixed handle, floating platen (10) leaves workpiece, after taking off workpiece, can restart next working cycles.
[0011]embodiment described in the utility model is only the description that preferred embodiment of the present utility model is carried out; not the utility model design and scope are limited; do not breaking away under the front topic of the utility model design philosophy; various modification and improvement that in this area, engineers and technicians make the technical solution of the utility model; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection, all be documented in claims.
