A planer knife grinder

technical field

The utility model relates to the technical field of grinding machine tools and related devices, in particular to a planer sharpener for a planer.

Background technique

The knife grinder was first called the end face grinder, which is widely used in the sheet metal industry. Knife sharpener, paper cutter sharpener, multi-function knife sharpener, double grinding head knife sharpener, round knife sharpener and so on.

Knife grinder is used to grind turning tools, drill bits, milling cutters, engraving knives and other knives. It is a necessary supporting equipment for computer engraving machines, die-cutting and milling machines, machining centers, and CNC. Universal knife sharpener mainly includes: end face sharpener, straight knife sharpener, CNC knife sharpener, automatic knife sharpener and so on. The sharpening machine is powerful, mainly reflected in the flexible and changeable indexing head attachment, so it has high requirements for operating technology, resulting in the existing sharpening machine being very dependent on professional and technical personnel. Due to the high labor cost at this stage, It directly leads to a sharp increase in the overall cost, which has also become a huge obstacle restricting the development of the sheet metal industry. This situation needs to be improved urgently.

At the same time, in the prior art, the sharpening machine has the disadvantages of inaccurate angle adjustment during use, low precision, high labor intensity and low efficiency.

Utility model content

The purpose of the utility model is to provide a planer knife sharpener for a planer, which has the advantages of simple structure, easy adjustment of angle, high precision and high processing efficiency in view of the shortcomings in the prior art.

The purpose of this utility model is achieved through the following technical solutions:

A planer knife grinder for a planer includes two grinding wheels set opposite to each other, the two grinding wheels are all inclined, and the forming angle formed between the two grinding wheels is the same Adaptation; the two grinding wheels are respectively driven to rotate synchronously by corresponding two driving devices.

Wherein, it also includes a tool clamping device for clamping the tool to be processed, driven by the tool clamping device, the tool to be processed moves linearly back and forth within the forming angle to grind the blade of the tool.

Wherein, the driving device is a motor, and each grinding wheel is fixed to the corresponding rotating shaft of the motor.

Wherein, the forming angle formed between the two grinding wheels is 90° to 110°.

Wherein, the tool clamping device includes a clamp capable of clamping a plurality of tools, the clamp is slidably engaged with a horizontal slide rail, and the clamp can slide reciprocally along the slide rail.

The beneficial effects of the utility model:

A planer knife grinder for a planer of the utility model includes two grinding wheels set opposite to each other, the two grinding wheels are both inclined, and the forming angle formed between the two grinding wheels is compatible with the required forming blade angle ; When processing the tool, the cutter head of the forming blade of the tool to be processed is placed in the forming angle formed by the two grinding wheels, and the two grinding wheels rotate synchronously under the drive of the corresponding driving device, so that the cutter of the tool can be polished separately The two sides of the head, so as to form the required blade angle; because the forming angle formed by the two grinding wheels can be adjusted according to the blade angle of the tool, so compared with the existing knife grinder, the utility model has a better The machine not only has the advantages of simple structure, easy adjustment of forming angle, high precision and high processing efficiency, but also reduces the dependence of tool processing on professional and technical personnel and reduces processing difficulty.

Description of drawings

Utilize accompanying drawing to further illustrate the utility model, but the embodiment in the accompanying drawing does not constitute any restriction to the utility model, for those of ordinary skill in the art, under the premise of not paying creative work, also can obtain according to following accompanying drawing Additional drawings.

Fig. 1 is a schematic structural view of a planer knife sharpener for a router of the present invention.

Reference numerals for Fig. 1:

Fixture 11, slide rail 12;

grinding wheel 2;

Motor 31, rotating shaft 32;

Knives 4.

Detailed ways

The utility model is further described in conjunction with the following examples.

A kind of planer knife grinder of the present utility model, as shown in Figure 1, comprises the tool clamping device for clamping the tool 4 to be processed, and the tool clamping device comprises the fixture 11 that can clamp a plurality of tools 4 , the clamp 11 is clamped on the horizontal slide rail 12 , and the clamp 11 can slide along the slide rail 12 , so that the tool 4 to be processed can move horizontally back and forth along the slide rail 12 .

The knife grinder also includes two grinding wheels 2 oppositely arranged, and the two grinding wheels 2 are all inclined, and the forming angle formed between the two grinding wheels 2 is adapted to the required forming edge angle; The two motors 31 are driven to rotate synchronously, and each grinding wheel 2 is fixed on the rotating shaft 32 of the corresponding motor 31. When processing the tool 4, it is only necessary to clamp the tool 4 to be processed by the tool 4 clamping device, and then the clamp 11 slides linearly along the track, so that the cutter head of the formed blade of the tool 4 to be processed is placed on the surface formed by the two grinding wheels 2. In the forming angle, the two grinding wheels 2 rotate synchronously under the drive of the corresponding driving device, so that the two sides of the cutter head of the tool 4 can be polished respectively, thereby forming the required blade angle; due to the forming angle formed by the two grinding wheels 2 Corresponding adjustments can be made according to the blade angle of the cutter 4. Therefore, compared with the existing knife sharpening machine, the knife sharpening machine of the present utility model not only has the advantages of simple structure, easy adjustment of forming angle, high precision and high processing efficiency, but also It reduces the dependence of the processing of the tool 4 on professional and technical personnel, and reduces the difficulty of processing; after the machining of the edge angle, the tool 4 is transferred to the next processing procedure, such as the processing of the Daojun chip breaker.

Wherein, the forming angle formed between the two grinding wheels 2 and the size of the two grinding wheels 2 can be adjusted accordingly according to the edge angle of the tool 4 actually processed.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than limiting the protection scope of the present utility model. Although the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art Personnel should understand that the technical solution of the utility model can be modified or equivalently replaced without departing from the essence and scope of the technical solution of the utility model.
