Detailed Description

The present invention will be described with reference to specific embodiments.

Fig. 1 is the utility model discloses fixing device's mounting structure schematic diagram, as shown in fig. 1, fixing device installs in frame 1, be fixed with upper guideway 12 and lower guideway 13 on the frame 1 inside wall. The upper guide rail 12 and the lower guide rail 13 are respectively connected with a lathe bed 6 in a sliding way. Fixing device includes: the setting is in tight mechanism 2 in top inside the frame 1, install first fixed plate 111 on the inside wall of frame 1, be equipped with first circular slot 112 on the first fixed plate 111.

Fig. 2 is the structure schematic diagram of the tightening mechanism of the present invention, as shown in fig. 2, the tightening mechanism 2 includes: the device comprises a cylinder 21 arranged in the frame 1, a piston 22 connected with the inner wall of the cylinder 21 in a sliding way, a connecting rod 23 fixed on the outer side surface of the piston 22, and a jacking plug 24 fixed on the outer side surface of the connecting rod 23. The projection of the jacking plug 24 to the bed body 6 is positioned on the side wall of the bed body 6.

The device uses the jacking mechanism 2 to fix the position of the lathe bed 6. The specific operation is that when the bed body 6 moves to the right position, the pump 25 receives a signal, charges air into the cylinder 21 through the pipeline 251, pushes the piston 22 to move, so that the connecting rod 23 pushes forward, and the puller plug 24 contacts with the side wall of the bed body 6. The material of the holding plug should be selected to have a higher coefficient of static friction than the material of the bed 6, and the surface roughness of the holding plug 24 should be high. The purpose of this is to apply pressure to the holding-down plug 24 so as to hold it against the side wall of the bed 6, and to hold down the bed 6 by the pressure itself and to restrict the bed 6 from moving forward and backward by friction. To achieve such an object, there are several places as follows.

Fig. 3 is a partial view of a portion a in fig. 2, and as shown in fig. 3, the bottom of the first circular groove 112 is provided with a groove 113. An end cover 5 is installed on the outer end face of the cylinder 21, and the end cover 5 is fixed at the bottom of the groove 113. The end cap 5 is provided to seal and fix the position of the cylinder 21. The recess 113 is provided to allow a portion of the cylinder 21 to be exposed for easy access to the cylinder 21.

The number of the tightening mechanisms 2 is two, one tightening mechanism 2 is positioned above the upper guide rail 12, and the other tightening mechanism 2 is positioned between the upper guide rail 12 and the lower guide rail 13. And the two tightening mechanisms 2 are not positioned on the same vertical line. Two tight mechanisms 2 in top are arranged to play a role in multiple fixation, and the relative arrangement of oblique lines is beneficial to mutual limitation and plays a larger role in limitation. One of the tightening mechanisms 2 is located above the upper rail 12, and the other tightening mechanism 2 is located between the upper rail 12 and the lower rail 13, thereby enlarging the restricted surface.

The side wall of the lathe bed 6 is fixed with a laser emitter 3, and the inner side wall of the frame 1 is fixed with a photosensitive element 4. The laser emitter 3 corresponds to the position of the photosensitive element 4. When the lathe bed 6 moves to the processing position, the laser emitted by the laser emitter 3 is opposite to the photosensitive element 4, and a photosensitive signal is received to control the operation of the pump 25. During the period of receiving the light-sensitive signal, the pump 25 charges the inside of the cylinder 21 with a certain amount of gas. The light-sensitive signal is terminated, the pump 25 is deflated and the pressure changes, causing the piston 22 to push back.

Except the above, other arrangements are conventional and are labeled in the drawings and the description of the drawings, and need not be repeated here.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
