Drill blade handle holding device

The present invention relates to the structural technology of a jig, and more particularly to a blade handle holding device for a drill bit.

The drill bit is a type of drilling tool that is now commonly used in the drilling of objects. Due to the repeated use of the drill bit, the surface of the drill bit is bound to wear out, which causes the drilling accuracy of the drill bit to decrease, resulting in the use of the drill bit. In order to extend the service life of the drill bit, the current practice is to use the worn surface of the drilled surface. The machine is ground to return the blade face to a state where it can be drilled with a precise aperture.

It is also known that the construction of the drill bit comprises a cylindrical blade shank, one end of which extends to form a cylindrical blade having a diameter different from that of the blade shank, and the blade surface is formed at one end of the blade. Before the blade surface is subjected to grinding by the grinder, the blade handle needs to be fixed by holding or clamping the blade to control the grinding precision of the blade face. The holding means that the jaws are tightened by the position of the circumference of the distribution or the like to move toward the center; the clamping means that the jaws are clamped by the two sides in a relatively close movement manner.

However, the jaws are fixed in the manner of holding or clamping, since the power of the jaws is usually from the pneumatic cylinder, and the output force of the pneumatic cylinder is fixed, so when the blade is receiving the grinder When grinding, the blade shank is easily affected by the force transmitted by the blade surface, and the grinding accuracy is easily controlled, so that the grinding accuracy of the blade surface is difficult to control.

In view of this, the purpose of the present invention is to improve the traditional fixed edge The problem of poor firmness when the handle is used.

In order to achieve the above object, the present invention provides a drill pipe holding device, the technical means comprising: an arm member, which is movably disposed on a vertical adjustment seat, and the arm member is displaced along an arc path by driving of a driver; a socket seated on the vertical adjustment seat and located in an arc path, the socket is formed with a receiving groove for placing a blade handle; wherein the arm member extends at one end to form a pressing portion for pressing the blade handle and A holding portion adjacent to the pressing portion, the holding portion is in contact with a pressing portion that is elastically deformed by pressing the blade handle.

In a further implementation, the utility model further comprises a fixing seat fixed on the vertical adjusting seat, wherein the fixing seat is connected to the arm member via two parallel connecting rods for restraining the arm member from being displaced along the arc path . A resilient member is disposed between the arm member and the fixed seat, and the arm member is returned to the original position by receiving the pushing of the elastic member.

In a further implementation, the vertical adjustment seat snail is assembled on a machine table, and a first clamping jaw and a second clamping jaw for holding the blade are slid on the machine table, and the first clamping jaw receives a first A horizontal drive is driven to move along a horizontal path, the second jaw being driven by a second horizontal drive to move in a horizontal path relatively close to and relatively away from the first jaw, the blade being seated in a horizontal path.

According to the above technical means, the technical effect that the present invention can produce is that the two-stage pressure applied to the blade shank by the pressing portion and the holding portion can be effectively compared with the conventional one-stage pressure applied to the blade shank. The lifting blade handle is firmly held when pressed, thereby controlling the grinding precision of the blade surface.
