Abstract

At present the spade is edged by grinding with an abrasive wheel machine by a person, the working environment is poor and the randomness of the labor intensity and the grinding quality is big; the qualified rate of products is low and the performance and the quality of the products are seriously affected. The grinding mode of the end surface of a cylinder-shaped abrasive wheel is used in the machinery and except that loading is operated by the person, other work is automatically finished by a gas to electricity device. The machinery is sort of adjusted to be used for the processing of the spade with different types and has strong applicability.

Description

Shovel sharpening machine

The utility model is used for grinding spade blade for end mill formula spade blade grinding machine.

The spade of domestic production at present is artificial with abrasive machine manual operations grinding, work under bad environment, and labour intensity is very big.Because the workman is reluctant to be engaged in this work and manual quality randomness, large quantities of spade sharpenings are defective, had a strong impact on product quality and serviceability, particularly influenced finishing smoothly of annual millions of spade export task.

The purpose of this utility model is a kind of well behaved machinery of design, to replace the heavy manual labor of workman, improves the qualification rate and the grinding quality of product.

Technical solution of the present utility model is made up of base (1), center base (2), workpiece location and clamping device (B), feed arrangement (C), grinding attachment (D) and filling device (E).Of the present utility model being characterised in that can be disposed feed arrangement (C) on the center base (2) that relatively moves on the base (1), be equipped with workpiece location and clamping device (B) on the top of feed arrangement (C), and its rear portion disposes filling device (E).Grinding attachment (D) is configured on the base (1), and vertically lifting.Leading truck (3) on center base (2) disposes guide groove (26), (27), and the feed arrangement (C) that spade (A) is installed on it can be done the curve feed motion along this guide groove.The dnockout guide plate (21) that is being fixedly connected and is having guide groove (28) at the rear portion of feed arrangement (C) makes filling device (E) move along a curved path along this guide groove, and (A) gets with spade.

The utlity model has following advantage and effect:

1. after machinery being adjusted accordingly, but the polytype spade of grinding.

2. but the speed step-less adjustment of feeding and dnockout.

3. except that artificial material loading, all the other each actions are carried out automatically, and last action is not in place, and back one action can not begin.

Accompanying drawing behind this paper is a structure diagram of the present utility model.Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Spade blade grinding machine of the present utility model adopts the cylindrical grinding wheel endface grinding method that the spade blade is carried out grinding.Except that the material loading of spade system by the manually-operated, the clamping of other work such as spade, the feeding during grinding, returning fast after the grinding unclamped getting of pressing plate and spade etc. and finished by gas-electric installation.

As shown in the figure, spade (A) is placed on the shovel seat (17), by positioning lever (13) location correct after, clamping cylinder (15) compresses it by the pressing plate (14) that links.Vibration during for the minimizing grinding, the spade rear end has push rod (16) to hold out against.Then, feeding cylinder (25) promote slide unit (7) and on the shovel seat, workpiece is done feeding, simultaneously, stirs roller (30) on the positioning lever by the inclined-plane (29) on the guide rail (6), and positioning lever is swung to below the grinding skin of workpiece.The roller (23) of both sides rolling in the guide groove (26) of the guide plate (4) of leading truck (3) both sides and (24), (27) before and after the slide unit is (during the dissimilar spade of grinding, the shape of guide groove is also different, its shape can be made according to counter the copying of spade blade, this is that those skilled in the art is conspicuous), thereby make spade by certain curvilinear motion, ground blade by the end face of cylinder grinding wheel.After grinding finished, slide unit was return fast, the interlock clamp loose, dnockout cylinder (20) promotes dnockout frame (19) fast spade is released the shovel seat, fall into transport vehicle, its movement locus is by the control of the guide groove (28) on the dnockout guide plate (21), and stroke is controlled by travel switch (22).

Cylinder grinding wheel (8) is installed on the axle of the motor (10) that is positioned on the rotating disk (11).Rotating disk slide plate (12) revolution relatively, thus grinding wheel spindle is tilted, and its angle can be regulated as requested.Slide plate can upper and lowerly move, and to adjust the position of emery wheel, adjusts cutting depth or changes emery wheel.Emery wheel has guard shield (9) protection outward.Slide unit has lubricating arrangement, and backplate (5) also is housed, and prevents abrasive dust, and sand grains enters in the slide unit guide rail.

Adjust requirements of one's work for adapting to, the relative position between center base (2) and the base (1) can move.

Claims

1, a kind of spade blade grinding machine, by base (1), center base (2), workpiece location and clamping device (B), feed arrangement (C), grinding attachment (D) and filling device (E) are formed, of the present utility model being characterised in that can be disposed feed arrangement (C) on the center base (2) that relatively moves on the base (1), be equipped with workpiece location and clamping device (B) on the top of feed arrangement (C), its rear portion disposes above-described filling device (E), grinding attachment (D) is configured on the base (1), and vertically lifting, leading truck (3) on center base (2) disposes guide groove (26), (27), feed arrangement (C) can be done the curve feed motion along this guide groove, the dnockout guide plate (21) that is being fixedly connected and is having guide groove (28) at the rear portion of feed arrangement (C), filling device (E) is moved along a curved path along this guide groove, and (A) gets with workpiece.

2, spade blade grinding machine according to claim 1, the guide rail (6) that it is characterized in that being contained on the leading truck (3) has an inclined-plane (29), the roller of stirring on the positioning lever (13) by this inclined-plane (30) swings to below the grinding skin of workpiece positioning lever (13), makes grinding not interfere phenomenon.
