Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a wide-blade grinding clamping device. Background Technology

[0002] A carbide wide-blade cutting tool is a type of cutting tool with a long, straight cutting edge. During machining, the long cutting edge scrapes the outer diameter of the crankshaft journal, requiring sharpening of the edge. Therefore, the rake face and flank face of the cutting edge are ground separately on a high-precision grinding machine to create a sharp cutting edge.

[0003] Chinese utility model patent application number 2023233069159 discloses a regrinding device for a wide cutting tool used in marine crankshaft machining. The device includes a worktable, a regrinding base, a wide cutting tool, a grinding wheel, and a connecting component. The regrinding base is inclined at a certain angle to the worktable. A portion of the outer contour of the regrinding base has multiple mounting surfaces arranged at a certain angle, and another portion has two reference surfaces. The reference surfaces have fixing devices for connecting the regrinding base to the worktable. The wide cutting tool is fixedly connected to one of the mounting surfaces via the connecting component. This device can regrind both the rake and flank faces of the wide cutting tool without reinstalling the tool, effectively improving grinding efficiency. However, this device still has the following two problems:

[0004] First, the straightness and roundness of the crankshaft journals have very high precision requirements. These precisions are mainly guaranteed by the cutting precision of the cutting edge of the wide tool, such as the straightness of the cutting edge. However, when the grinding base is fixed to the worktable, there is a lack of positioning structure, and it is not easy to guarantee the straightness after the wide tool is installed.

[0005] Secondly, different width cutters may require different grinding angles. Each grinding base is shaped by two reference surfaces and can often only be used to clamp the same type of width cutter. If the grinding angle is different, the corresponding grinding base needs to be replaced. Utility Model Content

DETAILED DESCRIPTION

[0028] The technical solutions in the typical embodiments of the present application will be described clearly and completely below by combining the drawings in the embodiments of the present application.

[0029] As shown in Figure 1 , Figure 2 and Figure 3 , the present embodiment provides a wide blade grinding clamping device, which comprises: a rotary electromagnetic workbench 1, a limit stop 2, a square pad 3, a mounting seat 4, a positioning block 5 and a wedge-shaped block 6. The wide blade 7 is clamped on the mounting seat 4 when being ground, and the structure of the wide blade is shown in Figure 5 , which has a rake face 71 and a relief face 72.

[0030] The rotary electromagnetic workbench 1 is a mature product in the prior art, and can also be called a rotary electromagnetic chuck, a grinder electromagnetic chuck, etc., and has a magnetic adsorption function.

[0031] It should be noted that the rotary electromagnetic workbench 1 has been used in a grinder, and the present embodiment determines the X direction and Y direction of the rotary electromagnetic workbench 1 according to the machine tool coordinate system.

[0032] As shown in Figure 1 , the limiting block 2 is installed at the rear of the table top of the rotary electromagnetic workbench 1, and has a first X-direction reference surface 21 on the front side. The front or rear, front or rear of the table top is determined based on the operator, with the front being closer to the operator and the rear being farther away from the operator. In order to facilitate processing, it is more appropriate to arrange the wide knife 7 at the front of the table top.

[0033] In the present embodiment, as shown in Figure 3 , the limiting block 2 is an angle steel, one inner side surface of which is attached to the side surface of the rotary electromagnetic workbench 1 and is fixed to the workbench by screws, and the other inner side surface is attached to the table top of the rotary electromagnetic workbench 1.

[0034] The limiting block 2 plays a limiting role and is also used as a positioning reference. In order to ensure the straightness of the subsequent process, the front side of the limiting block 2 has a first X-direction reference surface 21, i.e., the surface has high straightness in the X direction. The same applies to the second X-direction reference surface 42 and the third X-direction reference surface 43 described below.

[0035] As shown in Figure 1 and Figure 4 , the mounting seat 4 is magnetically adsorbed to the front of the table top of the rotary electromagnetic workbench 1 and has a second X-direction reference surface 42 on the rear side; the mounting seat 4 is provided with a plurality of connecting pieces 41 for connecting the wide knife 7 along the X direction.

[0036] In the present embodiment, the mounting seat 4 is provided with a reverse T-shaped slot along the X direction, which is a through slot, and the connecting piece 41 is formed by a T-shaped nut and a screw, the T-shaped nut is adapted to the reverse T-shaped slot and can slide therein.

[0037] The square pad 3 is abutted between the first X-direction reference surface 21 and the second X-direction reference surface 42 and is magnetically adsorbed to the table top of the rotary electromagnetic workbench 1.

[0038] The square cushion block 3 is provided with a plurality of, in the embodiment, three are provided. It can be understood that in other embodiments, the number of settings is not limited to the number of settings in the embodiment, and a longer piece can also be used, which can be designed according to actual needs. It is self-evident that the surface of the square cushion block 3 in contact with the first X-direction reference surface 21 and the second X-direction reference surface 42 should also have good straightness.

[0039] It should be noted that in the embodiment, not only the first X-direction reference surface 21, the second X-direction reference surface 42, the third X-direction reference surface and the square cushion block need to ensure the X-direction straightness, in essence, the rest of the surface contact or surface line contact also needs to be ensured, for example, the two side surfaces of the wedge block 6 and the two side surfaces of the positioning block 5, only some surfaces need to be used as reference surfaces, which is easy for those skilled in the art to understand and easy to implement. The surface of the part that needs to ensure straightness is clamped along the X-direction, and the grinding wheel of the grinding machine is used to grind along the X-direction.

[0040] The purpose of providing the square cushion block 3 is to reduce the size of the mounting seat 4 in the Y-direction, thereby reducing the size of the positioning block 5 and the wedge block 6.

[0041] As shown in Figure 4 The top of the mounting seat 4 is provided with an L-shaped open slot, which faces the operator and has only one slot wall. In the embodiment, the inverted T-shaped slot is provided at the front of the bottom of the L-shaped open slot, and the wide knife 7 is also installed in the slot.

[0042] It also includes a positioning block 5 and a wedge block 6 arranged along the X-direction, and both are connected with the bottom of the L-shaped open slot through a plurality of screws; specifically, the positioning block is connected with the bottom of the L-shaped open slot through a first screw 51, and the wedge block 6 is connected with the bottom of the L-shaped open slot through a second screw 61; the rear slot wall of the L-shaped open slot is a third X-direction reference surface 43, the wedge block 6 is arranged between the third X-direction reference surface 43 and the positioning block 5 and in surface contact with both, and the positioning block 5 contacts the opposite side of the wedge block 6 and abuts against the wide knife 7.

[0043] The screw hole of the positioning block 5 is expanded in the Y-direction, and under the extrusion of the wedge block 6, it has a certain displacement in the Y-direction.

[0044] The wedge block 6 and the positioning block 5 are installed on the mounting seat 4, and the two are in inclined surface contact. When the wedge block 6 is screwed tightly, the wedge block 6 moves downward, the inclined surface pushes the positioning block 5 to move forward, and the positioning block 5 pushes the wide knife to move forward, thereby adjusting the wide knife 7.

[0045] Specifically, the wide knife 7 mounting hole has a gap with the screw, which can have a slight forward and backward movement; when the wide knife 7 is manufactured, the back surface 73 needs to be ground to be parallel to the blade. However, during use, a certain deformation will occur; the second screw 61 of the wedge-shaped block 6 is screwed to different depths, the wedge-shaped block 6 pushes the positioning block 5 to produce different moving distances forward, so that the blade is parallel to the X direction.

[0046] In addition, due to the manufacturing of the wide knife 7, such as Figure 5 When the width size error is greater than the gap between the wide knife 7 mounting hole and the screw, at this time the back surface 73 of the wide knife 7 cannot support the positioning block 5 or cannot be put in; the positioning block 5 needs to be moved forward or backward as a whole, so that the positioning block 5 can support the back surface 73 of the wide knife 7. The second screw 61 of the wedge-shaped block 6 is screwed to the same depth, and the positioning block 5 is pushed as a whole by the wedge-shaped block 6.

[0047] There are multiple second screws 61, and the wide knife 7 has different lengths, according to the length of the wide knife 7 and the placement position, two of the second screws 61 can be selected for adjustment. During adjustment, the dial gauge is moved in the X direction, the blade of the wide knife 7 is checked whether it is parallel to the machine tool X axis, then it is judged which second screw 61 is selected, until the blade of the wide knife 7 is parallel to the machine tool X axis.

[0048] The specific working process is as follows: the rotary electromagnetic workbench 1 is powered on, the limiting block 2, the direction pad 3 and the mounting seat 4 are sequentially installed on the rotary electromagnetic workbench 1 in order; the mounting seat 4 is installed with the wedge-shaped block 6 and the positioning block 5, and the two are in inclined surface contact (usually only assembled at the first time of use), the wide knife is installed on the mounting seat 4, and the screw is pre-tightened (the screw for fixing the wide knife is not pressed tightly, but maintains contact with the wide knife), the second screw 61 of the wedge-shaped block 6 is adjusted by screwing, so as to realize the adjustment of the wide knife; after the wide knife 7 is adjusted, the screw is tightened to fix the wide knife 7 on the mounting seat 4.

[0049] Although the utility model has been disclosed as above with preferred embodiments, it is not intended to limit the utility model, and any person skilled in the art can make possible changes and modifications to the utility model technical scheme by using the above disclosed methods and technical contents without departing from the spirit and scope of the utility model, therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the utility model, which does not depart from the content of the utility model technical scheme, belongs to the protection scope of the utility model technical scheme.
