Four-sided restrained gantry line rail device

The invention relates to a device for a gantry processing machine, in particular to a four-sided restrained gantry line rail device.

The existing gantry rail device is provided with a sliding seat 80 as shown in FIG. 4 , and the sliding seat 80 is a block body that is disposed vertically. The front side of the sliding seat 80 is recessed with a receiving slot 81 . A sliding rail 82 is disposed on the two opposite inner side surfaces, and each of the sliding rails 82 is provided with a track groove 821. The spindle head 90 is disposed in the receiving groove 81 of the sliding seat 80, and the spindle is disposed. The height of the head 90 is greater than the height of the slider 80. The main shaft head 90 is respectively fixed with a pair of wire rails 91 corresponding to the two track grooves 821, and the two rails 91 are respectively worn on the two outer sides of the inner side surfaces of the through slots. In the two track grooves 821, the wire rails 91 on both sides of the spindle head 90 can be moved up and down with respect to the sliding block 80. However, the spindle head 90 only has two left and right wire rails 91 as support and sliding. Therefore, the load carrying force of the spindle head 90 and the covering force of the slider 80 are slightly insufficient.

In order to solve the above problem of the weight of the spindle head 90 in the gantry rail device and the insufficient coating force of the slider 80, the related art has developed a two-sided restrained gantry rail device as shown in FIG. 5, which is opposite to the inside of the slider 80A. Two sliding rails 82A are respectively disposed on the side surfaces of the sliding brackets 81A. The spindle heads 90A are disposed in the receiving slots 81A of the sliding brackets 80A. The spindle heads 90A are respectively provided with a line rail 91A corresponding to the positions of the sliding rails 82A. The number of the wire rails 91A of the spindle head 90A is increased, so that the slider 90A can enhance the covering force and the spindle head 90A can increase its load carrying capacity, and the movement precision and rigidity of the spindle head 90A are improved. The rear side of the insertion groove 81A of the carriage 80A is not provided with the slide rail 82A, so that the front and rear directions of the spindle head 90A are not restrained, so that the spindle head 90A is opposite during the use of the spindle head 90A. The carriage 80A is swayed back and forth, so that the accuracy of the movement of the spindle head 90A in the front and rear directions is affected.

In order to solve the problem that the spindle head 90A in the two-sided restrained gantry rail device is swayed before and after the slider 80A in use, the related art has also developed a three-sided restrained line device as shown in FIG. The two opposite inner sides of the receiving groove 81B of the seat 80B are respectively provided with a sliding track, and the rear side of the through groove 80B is provided with two rear sliding rails 82B. The sliding groove 81B of the sliding seat 80B is disposed in the receiving groove 81B. The spindle head 90B is disposed vertically, and the spindle head 90B is respectively provided with a line rail 91B corresponding to each of the sliding rails 82B. Since the number of the rails 91B of the spindle head 90B is increased, the slider 80B can strengthen the covering force and The gravity is loaded, and the movement precision and rigidity of the spindle head 90B are improved. However, the rear ends of the opposite inner sides of the insertion groove 81B are not provided with the slide rail 82B, and the rear side of the spindle head 90B is provided. The left and right directions are not restrained, so that during the use of the spindle head 90B, the spindle head 90B is swayed to the left and right with respect to the slider 80B, so that the movement accuracy of the spindle head 90B in the left and right directions is affected.

In order to solve the problem of the lack of the gravity of the spindle head and the lack of motion precision in the existing gantry rail device, and the lack of the insufficient coating force of the sliding seat, and the relative sway between the sliding seat and the spindle head, the main purpose of the present invention is to provide a The four-sided restrained gantry rail device, the main type of the main system is to set the slot in the sliding seat to be stepped, and the sliding rails correspond to a trapezoidal distribution, and the sliding head corresponding to the sliding seat is designed as a stepped type, so that the sliding seat The main shaft head is bounded by four sides, so that the contact area between each movable track and the main shaft head is increased, the effect of improving the covering property of the sliding head on the main shaft head is improved, and the problem of the swaying between the sliding seat and the main shaft head is improved.

The present invention solves the problem of the prior art, and the four-sided restrained gantry rail device comprises: a sliding seat, the sliding seat is a block body which is arranged vertically, and a front side of the sliding seat is recessed with a wearing groove, a first restraining surface and a second restraining surface are respectively formed on two sides of the inner bottom surface thereof, and the first restraining surface and the second restraining surface are opposite to each other and parallel to each other, the first restraining surface and The second restraining surface is gradually extended toward the opening of the opening slot to form a third restraining surface and a fourth restraining surface, and the third restraining surface and the fourth restraining surface are also facing each other and parallel to each other, and The distance between the third restraining surface and the fourth restraining surface is greater than the distance between the first restraining surface and the second restraining surface, and the sliding seat is erected at least one slide on each of the restraining surfaces of the wearing slot. Moving rails, each of which has a track groove recessed into the through slot; and a spindle head penetrating into the slot of the slide, the spindle head being disposed upright and longer than the The block of the slide, which corresponds to the first a position of the sliding track on the restraining surface forms a first mounting surface that faces and shapes in conformity with the first restraining surface, and the spindle head forms a position corresponding to the position of the sliding track on the second restraining surface The second mounting surface facing and conforming to the shape, the first mounting surface and the second mounting surface are gradually expanded toward the front side of the sliding seat to form a third mounting surface and a fourth a mounting surface, wherein the third mounting surface faces and conforms to the shape of the third binding surface, the fourth mounting surface faces and conforms to the shape of the fourth binding surface, and the third mounting surface and the fourth mounting surface The planes are parallel to each other, and the shape and position of each track groove are matched, and the mounting surfaces of the spindle head are respectively erected outwardly to form a line rail, and each line rail is respectively disposed in each track groove, so that the sliding on each restraining surface The track restrains the rails of each mounting surface and distributes the four rails of the spindle head into a trapezoidal shape.
