(V) detailed description of the preferred embodiments

In order to make the technical solution of the present invention better understood by those skilled in the art, the technical solution of the present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1 to 6, the utility model relates to a purlin end grinds auxiliary fixtures, including bottom plate 1, be connected with slide rail 2 on the 1 top surface of bottom plate, slide rail 2 top cooperation sliding connection has slider 21. The top surface of the sliding block 21 is rotatably connected with a rotating shaft 31, specifically, the top surface of the sliding block 21 is welded with a bearing, the rotating shaft 31 is installed in the bearing and keeps a vertical state, and the lower end of the rotating shaft 31 can freely rotate in the bearing. The top of the rotating shaft 31 is connected with a C-shaped placing plate 3 for placing purlins 8, so that the C-shaped placing plate 3 and the purlins 8 inside the C-shaped placing plate can freely rotate on the horizontal plane at any angle around the rotating shaft 31.

One end of the sliding rail 2 is provided with a motor 5 with the bottom connected to the bottom plate 1, as shown in fig. 2 and 4, and the output shaft end of the motor 5 is connected with a grinding wheel 51. During operation, place purlin 8 on the board is placed to the C shape, as shown in fig. 5, 6, make 8 medial surfaces of purlin paste tight C shape and place 3 medial surfaces of board, press purlin 8 and promote C shape to emery wheel 51 direction and place board 3, make the slider 21 that C shape was placed board 3 below slide on sliding rail 2, until 8 one end of purlin contacts and polishes with emery wheel 51, after polishing one end, revolute the rotatory C shape of axis of rotation 31 and place board 3 to 180, then promote C shape to emery wheel 51 direction and place board 3 and make 8 other ends of purlin and emery wheel 51 contact and polish. Can easily realize 180 accent commentaries on classics of purlin 8 through above-mentioned structure, do not need the manual work to remove the tune, convenient operation, labour saving and time saving.

The top surface of the C-shaped placing plate 3 is in threaded connection with a threaded compression bar 4, the lower end of the threaded compression bar 4 is connected with a pressing plate 41, and the upper end of the threaded compression bar 4 is connected with an adjusting knob 42. When the purlines 8 are placed on the C-shaped placing plate 3, the positions of the purlines 8 are adjusted to enable the inner side surfaces of the purlines to be tightly attached to the inner side surfaces of the C-shaped placing plate 3, the purlines 8 are guaranteed to be parallel to the C-shaped placing plate 3, and when the purlines 8 are rotated, the purlines 8 can be guaranteed to be perpendicular to the grinding wheels 51 in the length direction as long as the front side surfaces and the rear side surfaces of the C-shaped placing plate 3 are parallel to the grinding wheels 51. The adjusting knob 42 is rotated to drive the threaded compression rod 4 to rotate, so that the pressing plate 41 moves downwards to compress the top of the purline 8, and the polishing effect is prevented from being influenced by the fact that the purline 8 slides relatively on the C-shaped placing plate 3 in the end polishing process.

The bottom surface of the pressing plate 41 is connected with a rubber antiskid layer, so that the pressing plate 41 is prevented from being in rigid contact with the upper surface of the purline 8 to damage the surface paint layer of the purline 8, the friction coefficient is increased, and relative sliding between the purline 8 and the pressing plate 41 is further avoided.

The two sides of the sliding rail 2 close to one end of the grinding wheel 51 are connected and provided with guide plates 7, the bottoms of the guide plates 7 are connected to the bottom plate 1, and the inner side surfaces of the guide plates 7 are flush with the inner side surfaces of the C-shaped placing plates 3. As shown in fig. 6, when the purlin 8 is pushed towards the grinding wheel 51, in order to polish one end of the purlin 8 in contact with the grinding wheel 51 through the opening between the guide plates 7 on the two sides, the purlin 8 attached to the inner side surface of the C-shaped placing plate 3 needs to be attached to the inner side surface of the guide plate 7 and slide on the inner side surface of the guide plate 7 to move forwards, and since the guide plate 7 is perpendicular to the working surface of the grinding wheel 51, the end surface of the purlin 8 is indirectly ensured to be parallel to the working surface of the grinding wheel 51, and the grinding deviation is avoided in the polishing process.

The front side of the guide plate 7 is connected with a bell mouth 71, so that the purline 8 can be guided into the inner side of the guide plate 7 more easily and pushed to one side of the grinding wheel 51 along the inner side surface of the guide plate 7.

The one end that emery wheel 51 was kept away from to slip rail 2 is connected with end plate 6, and the leading flank of end plate 6 is perpendicular with slip rail 2, and end plate 6 has played the supplementary effect of aliging when the terminal surface was polished simultaneously of many purlins 8. When many purlins 8 end ground simultaneously, place on board 3 is placed to C shape with purlin 8 is whole, 3 medial surfaces are placed to the 8 medial surfaces of innermost purlin paste tight C shape, and the purlin 8 in the outside pastes tightly in proper order, then slides to end plate 6 one end, guarantees through end plate 6 that whole purlins 8 tip aligns, then compresses tightly and polishes to emery wheel 51 direction propelling movement through clamp plate 41 again.

The working process is as follows: place purlin 8 on the board is placed to C shape, as shown in fig. 5, 6, make 8 medial surfaces of purlin paste tight C shape and place board 3 medial surface, rotatory screw depression bar 4 makes clamp plate 41 downstream compress tightly purlin 8 and place board 3 to emery wheel 51 direction promotion C shape, make slider 21 that C shape was placed board 3 below slide on slide rail 2, until 8 one end of purlin contacts with emery wheel 51 and polishes, after polishing one end, revolute the rotatory C shape of axis of rotation 31 and place board 3 to 180, then promote C shape to emery wheel 51 direction and place board 3 and make 8 other ends of purlin contact with emery wheel 51 and polish.
