Description

Basement plane milling clamp for seating shoe of general motor

The utility model relates to milling fixture, is a kind of special fixture of milling electric machine stand foot plane.

At present, the structure of the used anchor clamps of domestic electric machine industry processing motor foot plane is, a garden shape positioning disk is only arranged, and a fixing screw rod is arranged on it, and pressing plate and nut are arranged on the screw rod.5 frees degree that this anchor clamps can only limit workpiece can not realize circumferential location, need artificial centering, locate unreasonable.Because spiro rod length can not be adjusted, positioning disk is circular, whenever changes a support specification, just need change screw rod and positioning disk, so the versatility of anchor clamps is relatively poor.The clamping of workpiece is realized by pressing plate by nut, needs nut revolution circle could be clamped workpiece, and clamp speeds is slower.

The purpose of this utility model is: provide a kind of location convenient, clamp speeds reaches the good special fixture of versatility soon, to satisfy the needs of producing motor in enormous quantities.

The utility model is for finishing goal of the invention, and the design of being taked is:

Design a clamp body [5], driving gear [27], driven gear [7] and tooth bar [6] are installed in forward position in clamp body [5], and location-plate [21], [10] are fixed on the front end of tooth bar.In clamp body [5] centre position, rear portion, swivel nut [30] is installed, screw rod [18] is installed in the swivel nut [30], mounting spring [13], platen [14] and binding nut [20] successively on the screw rod [18], three-pawl type briquetting [16] is installed on the platen [14], and positioning disk tower [9] is fixed on the clamp body [5].Gear [27] is identical with the number of teeth and the modulus of gear [7].Location-plate [21] is gone up a processing oblong slots [32] with location-plate [10], in order to adjust orientation distance, and on screw rod [18], binding nut [20] below mounting spherical packing ring [19].

Description of drawings: accompanying drawing 1 is a front view of the present utility model, and accompanying drawing 2 is vertical views of accompanying drawing 1, accompanying drawing 3 be in the accompanying drawing 2 A to view.

The contrast accompanying drawing elaborates to the utility model.

[5] are clamp bodies among the figure, and driving gear [27], driven gear [7] and tooth bar [6] are installed in it, and dress key [28] is gone up in rotating shaft [24], and gear [27] is fixed thereon.Gear [27] is identical with the number of teeth and the modulus of gear [7], gear [27], gear [7] and tooth bar [6] are synchronous, location-plate [21], location-plate [10] are installed in termination at tooth bar [6], the lateral attitude of location-plate [21], [10] can be adjusted in oblong slots [32], to adapt to electric machine stand footing different in width location.This structure has solved the circumferentially problem of location of workpiece, and the location is rationalized.Clamp body [5] is gone up fixed installation turriform positioning disk [9], and in order to place the workpiece of 6 specifications, to improve the versatility of anchor clamps, locking nut [11] is fastened on the tower tray [9].Embodying another good structure of anchor clamps versatility is, screw rod [18] swivel nut [30] structure, swivel nut [30] is installed in the centre position at clamp body [5] rear portion, swivel nut is processed with internal and external screw thread on [30], swivel nut [30] adopts T type slot bolt [29] to be fixed in the clamp body [5], clamping screw [18] is installed in the swivel nut [30], and its height can be adjusted the back and lock with nut [22] according to the workpiece adjustment that is clamped.The clamping structure of these anchor clamps adopts three-pawl type briquetting [16], for the ease of workpiece is installed, briquetting [16] is installed on the platen [14], and platen [14] is contained on the screw rod [18], when guaranteeing clamping work pieces, platen [14] only axially moves, and does not rotate, and goes up dress pin [17] at screw rod [18].Go up at screw rod [18], the below mounting spring [13] of briquetting [16], adjust the elastic force that ring [12] is used for adjusting spring [13] when clamping different support length, platen [14] is connected by bolt [15] with briquetting [16], and binding nut [20] is contained on the screw rod [18], and fastening nut [20] gets final product clamping work pieces.Front view of the present utility model is a working state figure, the clamping process of these anchor clamps is: earlier briquetting [16] is threaded to double dot dash line shown in Figure 2 position, then electric machine stand is contained on the location tower tray [9], clockwise direction turning handle [1], power is by handle set [23], rotating shaft [24] reaches on the driving gear [27], gear [27] rotates, driven gear [7] sky is enclosed within on the fixed axis [8], because it is identical with the number of teeth modulus of driving gear [27], so under the drive of gear [27], to counterclockwise rotating, main like this, driven gear drives two tooth bars [6] respectively and travels forward synchronously, realizes the location.

Back, workpiece location clamps, earlier be threaded to solid line position shown in Figure 2 with three briquettings [16] this moment, screw down clips jack panel [20] then, and clamping force is imported clamping force on the platen [14] into by spheric washer [19], platen [14] drives briquetting [16] and moves down, and workpiece is clamped.Because the effect of spheric washer [19] can guarantee that three briquettings [16] have unsteady function, make clamping very reliable.

The workpiece completion of processing, unclamp binding nut [20] slightly, spring [13] just can be upspring platen [14], briquetting [16] is threaded to Fig. 2 double dot dash line position, can unload workpiece, because adjusting ring [12] can move up and down along the external screw thread of swivel nut [30], electric machine stand spring [13] elastic force of processing need not change, so binding nut [20] turns less than half-turn, just can clamp or unclamp workpiece fast, clamp body [5] is fixed on the platen by positioning key [26], T type slot bolt [2], packing ring [3], nut [4].[25] are pins among the figure, and [31] are bolts.

The design that the utility model is taked, through practical proof, the workpiece location is reasonable, and clamp speeds is fast, and the versatility of anchor clamps is had greatly improved, applicable to six kinds of specification electric machine stand footing Milling Process.
