Description
Technical field
The utility model relates to and a kind of upright drill is used for the rest pad structure 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 floating combined support block 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 clamping combination support block that floats, comprise rectangle fixed block (1), rocker piece (2) and fastening sunk screw (3), the bottom of described rectangle fixed block (1) is provided with rectangle mount pad (1a), the top of rectangle fixed block (1) is provided with the through deep-slotted chip breaker (1b) in front and back, is provided with the tapped blind hole (1c) to downward-extension at the middle part of deep-slotted chip breaker (1b); Described rocker piece (2) is the crescent long strip block of mating with deep-slotted chip breaker (1b), and be just in time placed in deep-slotted chip breaker (1b), the middle part of crescent long strip 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 crescent long strip block end face respectively on extend to form 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 rectangle fixed block (1); An etched-off area (1e) is provided with in the middle part of the rear side of described rectangle fixed block (1), described etched-off area (1e) is positioned at the top of rectangle mount pad (1a), the below of deep-slotted chip breaker (1b), the rear of tapped blind hole (1c), and four angle position places of described rectangle mount pad (1a) are provided with loss of weight oblique angle (1f).
Preferred as such scheme, the top width of described rectangle fixed block (1) is equal with the width of rectangle mount pad (1c), and the waist width of rectangle fixed block (1) is less than or equal to 2/3 of top width.Optimize structure, alleviate the weight of rectangle fixed block, and make the rectangle mount pad of rectangle fixed block self-assembling formation after processing waist.
Further, described rectangle mount pad (1a) is provided with four installing holes (1d) in rectangular layout.Optimize quantity and the layout of installing hole, ensure rectangle fixed block to be firmly installed on upright drill.
The beneficial effects of the utility model:
(1) rectangle fixed block 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, after both can be made again to connect, rocker piece can swing by rectangle fixed block relatively, 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,
(2) under the prerequisite not affecting functional structure, an etched-off area being set in the middle part of the rear side of rectangle fixed block for arranging work piece holder, avoiding combination support block and fixture to interfere; Meanwhile, at four angle position places of rectangle mount pad, loss of weight oblique angle is set, weight reduction, reduces manufacturing cost.

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 clamping combination support block that floats, forms primarily of rectangle fixed block 1, rocker piece 2 and fastening sunk screw 3 three part.
Composition graphs 1---shown in Fig. 4, the bottom of rectangle fixed block 1 is provided with rectangle mount pad 1a, and rectangle 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 rectangle fixed block 1 is provided with the through deep-slotted chip breaker 1b in front and back, is provided with the tapped blind hole 1c to downward-extension at the middle part of deep-slotted chip breaker 1b.
Rocker piece 2 is the crescent long strip block of mating with deep-slotted chip breaker 1b, and is just in time placed in deep-slotted chip breaker 1b, and namely the radius of crescent long strip block is equal with the radius of deep-slotted chip breaker 1b.The middle part of crescent long strip 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 crescent long strip block end face respectively on extend to form 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 rectangle fixed block 1.
An etched-off area 1e is provided with in the middle part of the rear side of rectangle fixed block 1, etched-off area 1e is positioned at the top of rectangle mount pad 1a, the below of deep-slotted chip breaker 1b, the rear of tapped blind hole 1c, to ensure that the setting of etched-off area 1e can not affect function and the intensity of combination support block, because fixture is arranged on the rear of combination support block usually, therefore arrange etched-off area 1e to stretch into for fixture, avoid producing with fixture interfering.Four angle position places of rectangle mount pad 1a are provided with loss of weight oblique angle 1f.
