Abstract
The utility model discloses a kind of workpiece elastic bearing mechanism, comprise contour pad (1), rocker piece (2) and fastening sunk screw (3), the bottom of contour pad is provided with mount pad (1a), the top of contour pad is provided with spherical groove (1b), is provided with the tapped blind hole (1c) to downward-extension at the middle part of spherical groove; Rocker piece is the hemispherical block with spherical groove, and be just in time placed in spherical groove, the middle part of hemispherical block end face is provided with the countersunk head mounting hole (2a) corresponding with tapped blind hole position, the left and right sides of hemispherical block end face respectively on extend to form meniscate work mounting s face (2b); The bar portion of fastening sunk screw stretches in tapped blind hole through after countersunk head mounting hole, thus is connected with rocker piece by contour pad.The workpiece be exclusively used in bottom surface is coarse supports, and workpiece reliably can be located in conjunction with briquetting, prevents workpiece in boring procedure from waving.
Description
Technical field
The utility model relates to and a kind of upright drill is used for the elastic bearing mechanism of holding workpieces, belongs to production equipment supplementary structure.
Background technology
Upright drill is used for Workpiece boring, is usually placed in by workpiece on the fixed bearing block of upright drill workbench, then in conjunction with briquetting by Work-sheet pressing, carries out Workpiece boring after finally descending by the drill bit of upright drill.For the workpiece that bottom surface is smooth, can ensure that workpiece contacts preferably with fixed bearing block, then in conjunction with briquetting by Work-sheet pressing; But for the workpiece that bottom surface is coarse, workpiece cannot reliably compress by fixed bearing block and briquetting, and in drilling machine boring procedure, workpiece may wave, and causes bore error.
Utility model content
For above-mentioned technical problem, intend providing a kind of workpiece elastic bearing mechanism for upright drill, the workpiece be exclusively used in bottom surface is coarse supports, and workpiece reliably can be located in conjunction with briquetting, prevents workpiece in boring procedure from waving.
For this reason, the technical scheme that the utility model adopts is: a kind of workpiece elastic bearing mechanism, comprise contour pad (1), rocker piece (2) and fastening sunk screw (3), the bottom of described contour pad (1) is provided with mount pad (1a), the top of contour pad (1) is provided with spherical groove (1b), is provided with the tapped blind hole (1c) to downward-extension at the middle part of spherical groove (1b); Described rocker piece (2) is the hemispherical block mated with spherical groove (1b), and be just in time placed in spherical groove (1b), the middle part of hemispherical block end face is provided with the countersunk head mounting hole (2a) corresponding with tapped blind hole (1c) position, the left and right sides of hemispherical block end face respectively on extend to form meniscate work mounting s face (2b); The bar portion of described fastening sunk screw (3) stretches in tapped blind hole (1c) through after countersunk head mounting hole (2a), thus is connected with rocker piece (2) by contour pad (1).
Preferred as such scheme, the top width of described contour pad (1) is equal with the width of mount pad (1c), and the waist width of contour pad (1) is less than or equal to 2/3 of top width.Optimize structure, alleviate the weight of contour pad, and make the mount pad of contour pad self-assembling formation after processing waist.
Further, described mount pad (1a) is provided with four installing holes (1d) in rectangular layout.Optimize quantity and the layout of installing hole, ensure contour pad to be firmly installed on upright drill.
The beneficial effects of the utility model: contour pad is connected by sunk screw with rocker piece, because the hole that rocker piece passes through for fastening sunk screw is countersunk head mounting hole, screw termination and workpiece can be avoided to interfere, the rocker piece energy comprehensive swing of contour pad relatively after both can be made again to connect, on rocker piece after place work piece, the rocker piece end face left and right sides protrude work mounting s face by self adjustment after and workpiece bottom at least form two point cantact, again in conjunction with briquetting by Work-sheet pressing, the work mounting s location being particularly suitable for bottom surface coarse uses, avoid workpiece to swing in boring procedure, thus affect borehole accuracy.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view (not comprising fastening sunk screw) of Fig. 1.
Fig. 3 is the structural representation of contour pad.
Fig. 4 is the structural representation of rocker piece.
Detailed description of the invention
Below by embodiment also by reference to the accompanying drawings, the utility model is described in further detail:
As shown in Figure 1 and Figure 2, a kind of workpiece elastic bearing mechanism, forms primarily of contour pad 1, rocker piece 2 and fastening sunk screw 3 three part.
Composition graphs 1---shown in Fig. 4, the bottom of contour pad 1 is provided with mount pad 1a, mount pad 1a is provided with installing hole 1d, for being connected with the workbench of upright drill.Preferably, installing hole 1d totally four, and in rectangular layout, but the quantity of installing hole 1d is not limited to four.The top of contour pad 1 is provided with spherical groove 1b, is provided with the tapped blind hole 1c to downward-extension at the middle part of spherical groove 1b.
Rocker piece 2 is the hemispherical blocks mated with spherical groove 1b, and is just in time placed in spherical groove 1b, and namely the radius of hemispherical block is equal with the radius of spherical groove 1b.The middle part of hemispherical block end face is provided with the countersunk head mounting hole 2a corresponding with tapped blind hole 1c position, and counter sink portion and the bore portion of described countersunk head mounting hole 2a are mounting hole.The left and right sides of hemispherical block end face respectively on extend to form meniscate work mounting s face 2b for holding workpieces.The bar portion of fastening sunk screw 3 stretches in tapped blind hole 1c through after countersunk head mounting hole 2a, and the termination of fastening sunk screw 3 is positioned at the counter sink portion of countersunk head mounting hole 2a, thus is connected with rocker piece 2 by contour pad 1.
Preferably, the top width of contour pad 1 is equal with the width of mount pad 1c, and the waist width of contour pad 1 is less than or equal to 2/3 of top width, and processing and manufacturing is convenient in weight reduction.
Claims (3)
