Description

Auxiliary fixture for grinding inclined plane of V-shaped cutting edge

Technical Field

The utility model relates to a V-arrangement cutting edge inclined plane grinds supplementary anchor clamps.

Background

The V-shaped groove is machined in the metal sheet, and due to the fact that the groove width of the V-shaped groove is narrow, after stamping often occurs, the stamped V-shaped scraps are taken up by the tool bit and clamped into the V-shaped groove again, or the V-shaped scraps are directly adsorbed on the surface of the tool bit, and therefore subsequent stamping is affected. For this reason, the above-mentioned problems can be avoided by customizing the respective tool.

Fig. 1 provides a cutting tool, wherein a front end and a rear end of a tool bit of the cutting tool form a second-order step, a front end of the tool bit forms an inclined surface from front to back, and the inclined surface forms an included angle alpha with the rear end surface of the tool bit. The inclined plane of tool bit front end is the difficult point of polishing when polishing this cutter, can only pass through the angle of adjustment emery wheel under the general condition for the emery wheel slant direction gets into the polishing point of tool bit and polishes, because the emery wheel is the tool bit surface of progressively polishing, the angle of the in-process emery wheel of the gradual feed of emery wheel changes easily, thereby influences the formation on final tool bit inclined plane.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a V-arrangement cutting edge inclined plane grinds supplementary anchor clamps aims at solving above-mentioned problem.

In order to achieve the purpose, the technical scheme of the utility model is to design an auxiliary grinding clamp for the inclined plane of the V-shaped cutting edge, which comprises a base, a pressing block, a push rod and an inclined plane cushion block; the base is composed of a horizontally placed plate and two vertical plates vertical to the two sides of the horizontally placed plate, and the center of one vertical plate is provided with a hole for the push rod to pass through; the push rod penetrates through a hole in the center of the vertical plate, one end of the push rod is connected with the pressing block, and the pressing block moves in an area between the two vertical plates through the reciprocating motion of the push rod; the cross section of the inclined plane cushion block is L-shaped, the upper surface of the transverse end of the inclined plane cushion block forms an inclined plane from front to back, and the inclined plane and the horizontal plane form an included angle.

Furthermore, the outer wall of the push rod is provided with external threads, and the inner wall of a hole in a vertical plate of the base is provided with internal threads.

Furthermore, one end of the push rod, which is not connected with the pressing block, is provided with a rotating handle.

Furthermore, an annular wall is arranged at the rear end of the pressing block, and a cavity is formed inside the annular wall; one end of the push rod is connected with a bearing, the bearing is placed in a cavity formed by the annular wall at the rear end of the pressing block, and the ball of the bearing is attached to the inner wall of the annular wall; a wafer with a hole in the center is screwed on the annular wall at the rear end of the pressing block, so that the bearing is sealed in the cavity of the annular wall; the push rod passes through the hole on the circular sheet.

Furthermore, a baffle is arranged on one side of the base.

The utility model has the advantages and the beneficial effects that: the utility model relates to a V-arrangement cutting edge inclined plane grinds supplementary anchor clamps can realize the accurate polishing on V-arrangement cutting edge inclined plane.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

Example (b):

referring to fig. 2 and 3, an auxiliary grinding fixture for a V-shaped blade bevel comprises a base 1, a pressing block 2, a push rod 3 and a bevel cushion block 6; the base 1 is composed of a horizontally placed plate and two vertical plates perpendicular to two sides of the horizontally placed plate, and a hole for a push rod to pass through is formed in the center of one vertical plate; the push rod 3 penetrates through a hole in the center of the vertical plate, one end of the push rod 3 is connected with the pressing block 2, and the pressing block 2 moves in an area between the two vertical plates through the reciprocating motion of the push rod 3; the section of the inclined plane cushion block 6 is L-shaped, the upper surface of the transverse end of the inclined plane cushion block 6 forms an inclined plane from front to back, and the inclined plane and the horizontal plane form an included angle alpha.

The outer wall of the push rod 3 is provided with external threads, and the inner wall of a hole in a vertical plate of the base 1 is provided with internal threads.

And a rotating handle is arranged at one end of the push rod 3 which is not connected with the pressing block 2.

The rear end of the pressing block 2 is provided with an annular wall, and a cavity is formed inside the annular wall; one end of the push rod 3 is connected with a bearing 5, the bearing 5 is placed in a cavity formed by the annular wall at the rear end of the pressing block 2, and the ball of the bearing 5 is attached to the inner wall of the annular wall; a wafer with a hole in the center is screwed on the annular wall at the rear end of the pressing block 2, so that the bearing 5 is sealed in the cavity of the annular wall; the push rod 3 passes through a hole in the disc.

A baffle is arranged on one side of the base 1.

As shown in fig. 4 and fig. 1, when in use, the tool apron A inserted with the tool B is placed on the inclined surface of the inclined surface cushion block 6, and the included angle alpha between the inclined surface of the inclined surface cushion block 6 and the horizontal plane is equal to the included angle alpha between the inclined surface of the front end of the tool bit of the tool B and the rear end surface of the tool B, so that the inclined surface of the front end of the tool bit of the tool B is parallel to the horizontal plane at the moment. Then put into base 1 with inclined plane cushion 6 in, inclined plane cushion 6 rear end is pasting the baffle of base 1, and blade holder A one side is pasting the vertical plate of base 1 one end, then rotates and changes the handle, and push rod 3 removes for briquetting 2 sticiss the other end of blade holder A. And finally, placing the whole clamp on a workbench of polishing equipment, and feeding the grinding wheel downwards from the right above the cutter B to polish the front end inclined plane of the cutter head of the cutter B.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
