Abstract

The utility model relates to a grinding fixture suitable for inserting and fixing several workpieces. The utility model comprises a body which is provided with several insert channels and screw holes. Each insert channel stores one workpiece, and several fixing bolts are provided in the inner thread of the screw hole. When fixed,rotate the fixing bolt inwardly to make one end of the bolt leaned against the surface of one side of the workpiece, and the workpeice fixed in the grinding fixture under the stress. Utilizing many insert channels to store and fix the workpieces, the utility model improves the processing efficiency.

Description

Jig for grinding

[technical field]

The utility model is a kind of jig for grinding, the particularly a kind of jig for grinding that once can process a plurality of workpiece.

[background technology]

The attrition process of workpiece needs to realize that by grinding machine existing grinding machine comprises a workbench that the top of workbench is equiped with an emery wheel, before the grinding operation, workpiece is positioned on the workbench, workpiece is after fixing under the magnetic effect, adjust the relative position between emery wheel and the workpiece, can carry out grinding operation.

Yet, adopt existing Ginding process, once only to process a workpiece, process velocity is slow.In addition, if workpiece is ground out a compound angle, need emery wheel machine-shaping, or pad is established cushion block rule between workpiece bottom and workbench, very inconvenience operates.

[summary of the invention]

Main purpose of the present utility model is to provide a kind of jig for grinding that once can process a plurality of workpiece.

For reaching above-mentioned purpose, the utility model provides a kind of jig for grinding, is applicable to plug fixing a plurality of workpiece, and this jig for grinding comprises a body, is provided with some plant passages and some screws in this body, wherein, in these plant passages respectively in order to plug a workpiece; And be installed with some holding screws in these screws; In the time of fixedly, holding screw is inwardly rotated,, workpiece is fixed in the jig for grinding under pressure so that an end of holding screw presses the side surface to workpiece.

Compared to prior art, the utility model is provided with a plurality of plant passages, is used for plugging fixing a plurality of workpiece, helps improving the efficient of processing.

Fig. 2 is the generalized section when not plugging workpiece among first embodiment of the utility model jig for grinding.

Fig. 3 is for being inserted with the generalized section behind the workpiece among first embodiment of the utility model jig for grinding.

Fig. 4 is the generalized section when not plugging workpiece among second embodiment of the utility model jig for grinding.

[specific embodiment]

See also shown in Figure 1, the utility model jig for grinding is applicable to and plugs fixing a plurality of workpiece 50, this jig for grinding comprises a body 10, the bottom of body 10 has a trapezium structure, promptly, the bottom of body 10 is provided with first loading end 105 (horizontal), the both sides of this first loading end 105 are respectively equipped with one second loading end 106 and one the 3rd loading end 107, and folder is established an obtuse angle between this second loading end 106 and first loading end 105, and folder is established an obtuse angle between the 3rd loading end 107 and first loading end 105.And be provided with some plant path 10s 1 and some screws 102 in this body 10, wherein, these plant path 10s 1 are connected to the bottom of body 10 by the top of body 10, and in these plant path 10s 1 respectively in order to plug a workpiece 50.In present embodiment, be provided with five path 10s 1 of independently planting altogether, and these plant path 10s 1 offer the direction unanimity, all be skewed, for example, the inclination angle between first loading end 105 of workpiece 50 and body 10 is 45 degree.In present embodiment, an end of these screws 102 extends to plant path 10 1 place respectively, and these screws 102 are vertically extended inwards by a side of body 10.And be installed with some holding screws 20 in these screws 102; One end of these holding screws 20 is respectively equipped with an Actuator Division 201, and the outer circumference diameter of Actuator Division 201 is greater than the aperture of screw 102.In addition, these Actuator Divisions 201 are respectively equipped with hexagonal groove 2011 in, so that the die nut operation.

Please in conjunction with consulting Fig. 2 and shown in Figure 3, in the time of fixedly, earlier workpiece 50 is inserted in the plant path 10 1, after plugging the location, an end of workpiece 50 arrives at the bottom of plant path 10 1, and the processing end 501 of workpiece 50 is exposed, then, with inwardly rotation back locking of holding screw 20,, workpiece 50 is fixed in the jig for grinding under pressure so that an end of holding screw 20 presses the side surface to workpiece 50.

During grinding operation, earlier first loading end 105 of jig for grinding (being made by ferrous materials) is positioned over Grinder bench (icon not, work top is made by magnetic material) on, jig for grinding vertically is adsorbed under the magnetic effect on the Grinder bench, is ground by the processing end 501 of the emery wheel (not shown) above the Grinder bench to workpiece 50 again.Then, second loading end 106 of jig for grinding is positioned on the Grinder bench, grinds by the processing end 501 of the emery wheel above the Grinder bench again workpiece 50; Then, the 3rd loading end 107 of jig for grinding is positioned on the Grinder bench, grinds by the processing end 501 of the emery wheel above the Grinder bench again workpiece 50; Thereby finish grinding to the compound angle of workpiece 50.

During dismounting, with holding screw 20 to inner rotary, so that a side surface of an end whiz workpiece 50 of holding screw 20, so that the dismounting of workpiece 50.

See also shown in Figure 4, body 10 is a hollow form, the top of body 10 is provided with some first locating holes 103, and the bottom of body 10 is provided with some second locating holes 104, corresponding one by one between first locating hole 103 and second locating hole 104, to form a gradient (45 degree inclination angle), plant path 10 1 is formed between first locating hole 103 and second locating hole 104.
