Combination fixture for workpiece of grinding wheel cutting machine

technical field

The invention relates to a workpiece combination fixture of a grinding wheel cutting machine, which belongs to a fast and safe workpiece clamping device specially used for grinding wheel cutting machines in the technical field of mechanical processing.

Background technique

Cutting with grinding wheels is a common processing method for workpieces in the field of mechanical processing. In the prior art, when the grinding wheel cutting machine cuts the workpiece, it usually uses a fixed fixture to clamp it, such as a clamping plate or a screw clamping device. The phenomenon of chip sawing will damage the grinding wheel, reduce work efficiency, increase costs, and in serious cases, it will not be able to complete the cutting or even cause accidents.

Invention content:

The object of the present invention is to provide a kind of grinding wheel cutting machine workpiece combination fixture that can not only clamp the workpiece conveniently and quickly, but also can reduce the cutting resistance when the grinding wheel cutting machine is working, avoid the phenomenon of pinching the saw, and is not easy to damage the grinding wheel sheet, so as to improve the cutting efficiency. The working efficiency of the machine meets the needs of fast clamping of parts with large diameter or cross-sectional area during cutting.

The technical solution adopted by the present invention to solve its technical problems is:

A workpiece combination fixture for a grinding wheel cutting machine, which is composed of a clamping mechanism and an elastic movement mechanism, wherein the clamping mechanism includes a pressure plate and a bottom plate for clamping a workpiece, and the pressure plate and the bottom plate are provided with a Press the pressing plate and the bottom plate to fix the pressing screw, the workpiece is clamped in the middle by the pressing plate and the bottom plate, and adjusted and fixed by the pressing screw. Said elastic motion mechanism is below the clamping mechanism, including a lead screw, a cam is installed in the middle of the lead screw, and the lead screw nut is tightly connected with the workbench. A guide sleeve is installed on the workbench, and a guide post is arranged inside the guide sleeve. A spring is installed on the guide post. The guide post slides up and down inside the guide sleeve. Activity coordination. The lower side of the worktable is slidably matched with the guide rail through the fixed slider. When cutting and feeding, the motor drives the lead screw to rotate, and the lead screw rotates to drive the worktable and fixture to move forward and backward along the guide rail through the lead screw nut. Due to the action of the guide sleeve and the cam, the whole fixture moves along the guide rail and also makes the whole fixture move along the guide rail. The entire fixture moves up and down slightly, thereby driving the workpiece between the bottom plate and the pressure plate to move back and forth and up and down, reducing the cutting resistance when the grinding wheel cutting machine is working, avoiding the phenomenon of pinching the saw, not easy to damage the grinding wheel, and realizing cutting.

In order to adjust the clamping degree of the workpiece, an adjusting bolt which is threadedly connected with the pressing plate to adjust the clamping degree of the pressing plate and the base plate is provided between the pressing plate and the base plate.

In order to adjust the clamping position of the workpiece and adapt to workpieces of different cross-sectional sizes, a "T" groove is provided on the upper plate of the bottom plate, and the lower end of the compression screw is slidingly fitted with the "T" groove.

The beneficial effects of the present invention are: the workpiece can be clamped conveniently and quickly, and the workpiece has back and forth and up and down reciprocating combined movements during the cutting process, which is beneficial to reduce the cutting resistance, facilitate the discharge of chips, avoid the phenomenon of pinching the saw, and prevent damage to the grinding wheel. Improve the working efficiency of the grinding wheel cutting machine and make the cutting process safer.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and the specific embodiments given in the accompanying drawings.

See Fig. 1 and Fig. 2, a kind of grinding wheel cutting machine workpiece combination fixture is made up of clamping mechanism and elastic movement mechanism, and said clamping mechanism includes clamping plate 8 and bottom plate 9 of clamping workpiece, and workpiece 4 is clamped on the clamping plate 8 and between the base plate 9. Between the upper side of the pressure plate 8 and the bottom plate 9, there are compression screw rods 6 and compression nuts 5 that cooperate with the light holes of the pressure plate 8. Adjust the compression nuts 5 to compress or loosen the clamping of the workpiece. hold or tightness. The upper panel of the base plate 9 is provided with a "T" groove, and the lower end of the compression screw 6 is slidably matched with the "T" groove, so as to adjust the clamping position of the workpiece and adapt to workpieces of different cross-sectional sizes. An adjusting bolt 7 threadedly connected with the pressing plate 8 is provided between the pressing plate 8 and the bottom plate 9 on the other side of the upper end of the pressing plate 8, to adjust the clamping degree of the workpiece or make fine adjustments. Said elastic motion mechanism is below the clamping mechanism, including a lead screw 11, and the middle part of the lead screw 11 is equipped with a cam 16 through a stopper 3, a key 2, and a lead screw nut 15, and the lead screw nut 15 is tightly connected with a workbench 13 . Four sets of guide sleeves 1 are fixedly installed on the workbench. Guide posts 17 are arranged inside the guide sleeves 1. Springs 10 are mounted on the guide posts 17. The guide posts 17 slide up and down in the guide sleeves. The tops of the guide posts 17 are located on the bottom plate 9.
