The grinding compression device is characterized in that the frame (1) is equipped with an air cylinder (3), wherein, the air cylinder is hinged with a transmission mechanism; the transmission mechanism is hinged with a pressure bar (4) capable of clamping the workpiece; and the frame at one side of the locating tooling table (2) is equipped with a grinding wheel (5) capable of grinding the workpiece.

Description

Universal joint blank grinding hold down gag
Technical field
The utility model relates to a kind of processing unit (plant) of universal joint blank, especially relates to a kind of universal joint blank grinding hold down gag.
Background technology
Universal-joint cross trunnion of the prior art is generally all formed by middle axis body and with the arm that middle axis body links into an integrated entity.Chinese patent discloses a kind of cross axle grinding machine, and (Granted publication number: CN 201064863Y), it comprises support, main spindle box, grinding carriage tool, track and tailstock item point; Support is provided with cross track and long rails, and cross track one end is fixed with main spindle box, and main shaft one end that is provided with on the main spindle box connects motor by belt, and the main shaft other end connects workpiece chuck; The cross track other end is provided with tailstock centre, and tailstock centre is coaxial relative with the workpiece chuck on the main shaft; Long rails is provided with the grinding carriage tool that can advance and retreat, and grinding carriage tool below is provided with the servomechanism installation of fast advance and retreat; Main shaft is hollow, and an end passes thrust bearing, bearing cap, two fixedly connected belt pulleys of flat contact ball bearing, and two flat contact ball bearings are fixedly connected on the main spindle box housing by bolt, bearing cap; The main shaft other end is cone, and the centerless fixture fixed disk that its end is provided with connects workpiece chuck by bolt, and its tapered hole, core hole can be equipped with top in the hole; The Biserial cylindrical roller bearing that its poppet surface is provided with is fixed on the main spindle box housing by bolt, bearing cap; The grinding carriage tool comprises: bracing frame and grinding wheel spindle, and the grinding wheel spindle one end fixed emery wheel chuck that bracing frame upper end is provided with, other end fast pulley, belt pulley links to each other with motor on being fixed on bracing frame by belt; The bracing frame lower end is by being bolted to getting on the right track of long rails.But this grinding machine can't compress workpiece, adds man-hour at the mill pin, the easy deviation post of workpiece, thus produce substandard products.
The utility model content
The utility model provides a kind of universal joint blank grinding hold down gag, and it mainly is to solve the existing in prior technology grinding machine can't compress workpiece, adds man-hour at the mill pin, the easy deviation post of workpiece, thereby the technical problem of generation substandard products etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Universal joint blank grinding hold down gag of the present utility model, comprise frame, frame is provided with the positioning fixture bench that can locate workpiece, described frame is provided with cylinder, cylinder is hinged with transmission mechanism, but transmission mechanism is hinged with the depression bar of workpiece pressing, and the frame of positioning fixture bench one side is provided with the emery wheel that can grind the pin workpiece.Cylinder can obliquely be provided with, and after its push rod moved obliquely upward, by the transmission of transmission mechanism, depression bar can move downward, thereby with Work-sheet pressing.At this moment thereby emery wheel can grind pin processing to workpiece near workpiece.
As preferably, described transmission mechanism includes the connecting rod of " L " type, and connecting rod one end is hinged on the push rod of cylinder, and the connecting rod other end is hinged on the depression bar, and the middle part of connecting rod is hinged with support bar, and support bar is fixed on the frame." L " type connecting rod bends in the middle, and the two ends of connecting rod are hinged with ejecting rod of cylinder, depression bar upper end respectively, and the push rod of cylinder is after moving obliquely upward like this, and connecting rod can be swung, thereby depression bar can move up and down.Transmission mechanism also can replace to other mechanism that the power of cylinder can be converted into the pressure of push rod, and cylinder also can be replaced by hydraulic cylinder.
As preferably, described positioning fixture bench is fixed on the base plate, and base plate is fixed on the frame by securing member.The width of base plate is greater than the width of positioning fixture bench bottom, so positioning fixture bench can will share the base plate place in bearing when Work-sheet pressing, prevents that positioning fixture bench from causing damage owing to pressure is excessive.
As preferably, described emery wheel is provided with dial, can be used for measuring the position that emery wheel rotates.
Therefore, the utility model is equiped with the connecting rod of cylinder and " L " type on frame, can make the depression bar workpiece pressing by the power of cylinder, moves comparatively easyly, and the operation that compresses is comparatively simple, and manufacturing cost is lower, and is simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is a kind of structural representations of the utility model emery wheel.
Parts, position and numbering among the figure: frame 1, positioning fixture bench 2, cylinder 3, depression bar 4, emery wheel 5, connecting rod 6, support bar 7, base plate 8, dial 9, workpiece 10.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the universal joint blank grinding hold down gag that this is routine, as Fig. 1, a frame 1 is arranged, frame is provided with the positioning fixture bench 2 that can locate workpiece 10, and the positioning fixture bench bottom is fixed on the base plate 8, and base plate is fixed on the frame by securing member.Frame is provided with cylinder 3, and cylinder is hinged with the connecting rod 6 of " L " type, and the other end of connecting rod is hinged with can be with the depression bar 4 of Work-sheet pressing to the positioning fixture bench, and the middle part of connecting rod is hinged with support bar 7, and support bar is fixed on the frame.The frame of positioning fixture bench one side is provided with the emery wheel 5 that can grind the pin workpiece, and as Fig. 2, emery wheel is provided with dial 9.
During use, workpiece 10 is put in the positioning fixture bench 2, started cylinder 3, the push rod of cylinder moves obliquely upward, thus 6 swings of the connecting rod of " L " type of drive, depression bar 4 downward workpiece pressings form lockmaking, and emery wheel 5 is near grinding pin processing behind the workpiece.
The above only is a specific embodiment of the utility model, but architectural feature of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and variation of being done or modification all are encompassed among the claim of the present utility model.
