Detailed Description
The invention is explained in more detail below with reference to the figures and examples.
Referring to fig. 1-11, the invention relates to an embroidery frame structure with a Y-direction drive matched with a front auxiliary rail and a rear auxiliary rail, which comprises a bedplate 1, a frame 2, an X auxiliary rail member 3, a Y front auxiliary rail member 4, a Y rear auxiliary rail member 5 and two connecting plate assemblies 6. Wherein, frame 2 sets up on platen 1, and frame 2 includes preceding frame 21, back frame 22, left frame 23, right frame 24, and the structure that is the cuboid that this four frames constitute, and frame 2's effect is used for fixed cloth work or material rest, and for the convenience of customers' change to cloth work or material rest, the structural setting of frame 2 can set up to be convenient for dismantlement formula. In general, the front frame 21 and the rear frame 22 are wide, and therefore, one of the front frame 21 and the rear frame 22 is detachably configured, or the front frame 21 and the rear frame 22 are both detachably configured, which is relatively good for space utilization of the cloth frame and relatively convenient for installation and fixation. In the present embodiment, the detachable cloth holder 200 is installed on the inner side surfaces of the front frame 21 and the rear frame 22, and the front frame 21, the rear frame 22 and the two cloth holders 200 form an integral structure of the frame 2.
The X-sub-rail member 3, the Y-front sub-rail member 4, the Y-rear sub-rail member 5 and the connecting plate assembly 6 form a mounting connection of the frame 2 and a total framework for moving and walking in the X direction and the Y direction. Wherein, in the present embodiment, for the X secondary rail 3, it is arranged to the right and is slidably connected with the right frame 24 of the frame 2. In fact, the position of the X-sub rail member 3 can be slidably connected to the left frame 23 of the frame 2, so that the whole structure is a left-right mirror image of the structure of the present embodiment, and is substantially identical in structure. According to the structural layout of the present embodiment, in the process of the frame 2 moving in the X direction, the left frame 23 of the frame 2 is likely to shake near the front frame 21, and when the X direction stroke of the frame 2 is large, the shaking phenomenon of the left front frame of the frame 2, i.e. the left frame 23, near the front frame 21 will continue to occur and the shaking amplitude will gradually increase, and in the state of the frame 2 being unstable due to the local shaking of the frame 2, the needle breakage phenomenon is likely to occur. And under the structural arrangement that the frame 2 is provided with Y double auxiliary rails, namely the Y front auxiliary rail part 4 and the Y rear auxiliary rail part 5, the front frame 21 can be stabilized through the Y front auxiliary rail part 4, so that the left front frame is pressed, the jumping amplitude of the left front frame is reduced, and the shaking phenomenon of the left front frame is solved.

According to the size of the Y-direction stroke of the frame 2 and the span of the right frame 24 in this embodiment, two sliding connection points a are provided, and the two connection points are symmetrical with respect to the right frame 24. Regarding the sliding connection point B, the front frame 21 is provided with the sliding connection point B at least at the frame section far away from the X sub-rail member and the Y front sub-rail, in this embodiment, at least one sliding connection point B is provided at the position of the front frame 21 near the left frame 23, because when the frame 2 moves in the X direction, the position of the frame 2 most prone to shake phenomenon is the left front frame, and therefore the sliding connection point provided at the position can effectively press the left front frame to reduce the jumping amplitude. In order to ensure that the left front frame of the frame 2 does not shake, two points are generally considered, that is, firstly, the length of the front frame 21 and the specification setting of the frame 2, and secondly, the connection stability between the member performing the sliding connection and the Y front sub rail 4, and if the member has a good sliding connection performance, the sliding connection point B does not need to be excessively provided. In the present embodiment, two sliding connection points B are provided, and both of the two sliding connection points are located in the left half section of the front frame 21, with one of the sliding connection points being located near the left frame 23. For the Y rear sub rail member 5, it is slidably connected to the rear frame 22 of the frame 2, and a plurality of sliding connection points C are provided, in order to ensure the structural stability of the left frame 23 of the frame 2 during the X-direction stroke, because one of the connection points of the rear frame 22 and the Y rear sub rail member 5 is provided at the rear frame 22 close to the left frame 23, and the sliding connection points C of the front frame 21 are provided in such a way as to be matched with the sliding connection points C of the front frame 21, so that the structural stability of the left frame 23 can be improved, and the remaining sliding connection points C of the rear frame 22 can be uniformly dispersed in the remaining frame segments of the rear frame 22. In the present embodiment, the sliding connection points C of the rear frame 22 and the Y rear sub rail 5 are set to four.
