Abstract

The utility model relates to a large-sized workpiece machining pressing device used for pressing and fixing workpieces on a working tabletop of a machine tool when machining large-sized workpieces. The large-sized workpiece machining pressing device consists of a press plate, a screw stem, a hold-down nut and a supporter, the screw steam is inserted in the press plate via a through slot arranged on the press plate, the hold-down nut is screwed to the upper end of the screw stem, the lower end of the screw stem is provided with a T-shaped head matching with a T-shaped groove, the rear end of the press plate is supported on the supporter parallel to the screw stem, and the supporter is formed by an upper supporter and a lower supporter which are screwed via threads. When used for pressing workpieces with different clamping heights and sizes, the pressing device can easily keep a press block and the working tabletop of the machine tool balanced, thereby saving assisting time of workpiece machining and increasing production efficiency. In addition, the pressing device is simple in structure and convenient and easy in operation.

Description

Large-scale workpiece processing hold down gag
Technical field
The utility model relates to the hold down gag of workpiece in the field of machining, particularly when the machining large workpiece, is used for the large-scale workpiece that Work-sheet pressing is fixed on the platen face is processed hold down gag.
Background technology
On lathe during processing work, clamping workpiece must be fixed on the work top of lathe, the work top of lathe is provided with many T type grooves that are used for the clamping fixation workpiece, and by this T type groove, hold down gag can be fixed on Work-sheet pressing on the work top of lathe.
Hold down gag is made up of pressing plate, screw rod, clamp nut and supporting mass, pressing plate vertically offers groove along it, screw rod interts in pressing plate by this groove, clamp nut is screwed in the screw rod upper end, the screw rod lower end has the T connector with T type groove coupling, and pressing back-end is supported on the supporting mass parallel with screw rod.When workpiece pressing, it is the T type groove that the T connector of screw rod lower end is placed the platen face, and the front end of pressing plate is pressed on the workpiece that is positioned on the platen face, screw clamp nut, then the pressing plate two ends compress workpiece and supporting mass simultaneously, thereby realize workpiece fixing on the platen face.
Hold down gag is at workpiece pressing, particularly during large-scale workpiece, necessarily requires pressing plate and platen face keeping parallelism, even pressing plate is in level, like this, workpiece could be pressed on the platen face reliably.But because the height dimension of different workpieces clamping is different, and the height dimension of the supporting mass in the same hold down gag is certain, and this just makes same hold down gag can not satisfy the requirement that compresses of different workpieces.In order to address this problem, be to adopt the mode of increase and decrease cushion block on supporting mass to solve at present, promptly when compressing the big workpiece of clamping height dimension, increase the cushion block on the supporting mass,, make briquetting and platen face keeping parallelism to increase the height dimension of supporting mass, and when compressing the little workpiece of clamping height dimension, cut the cushion block on the supporting mass,, make briquetting and platen face keeping parallelism to reduce the height dimension of supporting mass.In actual mechanical process, such operation bothers very much, reaches suitable height dimension in order to make supporting mass, and operating personnel often will spend the more time, thereby has increased the non-cutting time of workpiece processing, has reduced production efficiency.
The utility model content
The purpose of this utility model provides a kind of large-scale workpiece processing hold down gag, when compressing the workpiece of different clamping height dimensions, can make briquetting and platen face keeping parallelism easily.
Large-scale workpiece processing hold down gag described in the utility model, form by pressing plate, screw rod, clamp nut and supporting mass, screw rod interts in pressing plate by the groove of offering on the pressing plate, clamp nut is screwed in the screw rod upper end, the screw rod lower end has the T connector with T type groove coupling, pressing back-end is supported on the supporting mass parallel with screw rod, and described supporting mass is spun by screw thread by upper bearing body and lower bearing body and forms.
With hold down gag workpiece pressing described in the utility model the time, earlier the T connector of screw rod lower end is placed the T type groove of platen, and the front end of pressing plate is pressed on the workpiece that is positioned on the platen face, at this moment, the pressing plate two ends are supported on respectively on supporting mass and the workpiece, afterwards, by the upper bearing body of regulating supporting mass and the height that the degree of spinning between the lower bearing body is regulated supporting mass, when making pressing plate be in the state parallel with the platen face, screw clamp nut again, thereby realize the secure fixation of workpiece on the platen face.
Hold down gag described in the utility model forms owing to its supporting mass is spun by screw thread by upper bearing body and lower bearing body, thereby the height of supporting mass can be regulated easily, like this when compressing the workpiece of different clamping height dimensions, can make briquetting and platen face keeping parallelism easily, thereby saved the non-cutting time of workpiece processing, improved production efficiency; This hold down gag is simple in structure, and is easy to operate easy.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 is the front view of large-scale workpiece processing hold down gag described in the utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the view of this hold down gag when workpiece pressing.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, this large-scale workpiece processing hold down gag is by pressing plate 2, screw rod 1, clamp nut 3 and supporting mass are formed, screw rod 1 interts in pressing plate 2 by the groove of offering on the pressing plate 26, clamp nut 3 is screwed in screw rod 1 upper end, screw rod 1 lower end has the T connector with T type groove coupling, pressing plate 2 rear ends are supported on the supporting mass parallel with screw rod 1, described supporting mass is spun by screw thread by upper bearing body 4 and lower bearing body 5 and forms, wherein lower bearing body 5 is for being provided with internal thread and lower end tubular structure with the level, and upper bearing body 4 is for being provided with external screw thread and upper end rod shaped structure with the level.
During workpiece pressing, earlier the T connector of screw rod 1 lower end is placed the T type groove 9 of platen 7, and the front end of pressing plate 2 is pressed on the workpiece 8 that is positioned on the platen 7, at this moment, pressing plate 2 two ends are supported on respectively on supporting mass and the workpiece 8, afterwards, by the upper bearing body 4 of regulating supporting mass and the height that the degree of spinning between the lower bearing body 5 is regulated supporting mass, when making pressing plate 2 be in the state parallel with the platen face, screw clamp nut 3 again, thereby realize the secure fixation of workpiece 8 on platen 7.
