Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1 and 2, the special workpiece positioner for the machining center comprises a fixed bottom plate 1, wherein a fixed bolt 2 is connected inside the fixed bottom plate 1 in a sliding way, a T-shaped block 3 is connected to the outer wall of the fixed bolt 2 in a threaded way, a sliding seat 4 is connected to the outer wall of the fixed bolt 2 in a rotating way, a first top plate 5 is fixedly connected to the outer wall of the fixed bolt 2, the outer wall of the first top plate 5 is connected inside the sliding seat 4 in a sliding way, a first spring 6 is sleeved on the outer wall of the fixed bolt 2, a fixed seat 7 is fixedly connected to the outer wall of the fixed bottom plate 1, a sliding rod 8 is connected inside the fixed seat 7 in a sliding way, a second top plate 9 is fixedly connected to the outer wall of the sliding rod 8 in a sliding way, a supporting plate 11 is fixedly connected to the outer wall of the sliding rod 8 in a sleeved way, a second spring 10 is sleeved on the outer wall of the fixed bottom plate 1 in a sliding way, and a locking plate 12 is internally provided with a limiting component;
Specifically, the fixing bolt 2 is rotated to penetrate through the T-shaped block 3, so that the clamping of the fixing base plate 1 and the T-shaped block 3 to the workbench is realized. As the fixing bolt 2 continues to rotate, the first top plate 5 starts to exert pressure on the first spring 6, causing compression thereof. The elastic force of the first spring 6 acts against the connection between the fixing bolt 2 and the T-block 3, enhancing its stability. Then, the second top plate 9 is pushed by the force of the second spring 10, so as to drive the sliding rod 8 to move downwards. This process continues until the support plate 11 is fully seated against the table surface, providing additional stability to the holder. This not only ensures the stability of the device during the process, but also effectively extends the life of the holder because damage due to vibrations or misalignment is reduced.
Referring to fig. 1 and 3, the limiting assembly comprises a screw rod 18, wherein the outer wall of the screw rod 18 is in sliding connection with the inside of a locking plate 12, a nut 19 is in threaded connection with the outer wall of the screw rod 18, one end of a first spring 6 is fixedly connected with the inside of a sliding seat 4, the other end of the first spring 6 is fixedly connected with the outer wall of a first top plate 5, one end of a second spring 10 is fixedly connected with the inside of a fixed seat 7, the other end of the second spring 10 is fixedly connected with the outer wall of a second top plate 9, a limiting bolt 13 is in threaded connection with the inside of the locking plate 12, a limiting hole 14 is formed in the inside of the fixed bottom plate 1, the outer wall of the limiting bolt 13 is in threaded connection with the inside of the limiting hole 14, a sliding plate 15 is in threaded connection with the outside of the outer wall of the locking plate 12, a sliding plate 15 is in sliding connection with the inside of the fixed bottom plate 1, a movable bolt 16 is in threaded connection with the inside of the sliding plate 16, a sliding groove 17 is formed in the inside of the fixed bottom plate 1, and the outer wall of the sliding plate 15 is in sliding plate 17 in sliding connection with the inside of the sliding groove 17.
Specifically, when the position of the locking plate 12 needs to be adjusted, the locking plate 12 is only slightly pushed to slide on the surface of the fixed bottom plate 1. When the locking plate 12 is slid to a specific position, it can be fixed in the corresponding limit hole 14 by rotating the limit bolt 13. The locking plate 12 is fixed by screwing the limit bolts 13. This is not only simple and practical, but also ensures that the locking plate 12 remains stable during operation and does not move due to external forces. Further, by turning the movable bolt 16, the slide plate 15 is fixed inside the fixed base plate 1, thereby achieving further fixation of the position of the locking plate 12. This not only improves the stability of the locking plate 12, but also makes the entire holder stronger and more reliable.
The working principle is that when the fixing bottom plate 1 needs to be firmly fixed, the fixing bolts 2 are rotated towards the inside of the T-shaped block 3, so that the fixing bottom plate 1 and the T-shaped block 3 can clamp a workbench, the fixing bottom plate 1 is preliminarily fixed, meanwhile, the fixing bolts 2 push the first top plate 5 to compress the first springs 6 when rotating, the first springs 6 can strengthen the connection between the fixing bolts 2 and the T-shaped block 3 through elastic force, the second top plate 9 is pushed by the second springs 10 to drive the sliding rods 8 to move downwards until the supporting plates 11 are completely tightly attached to the workbench, the effect of firmly fixing the fixator on a machining platform is achieved, the stability of the fixator is improved, the service life of the fixator is prolonged, when the position of the locking plate 12 needs to be adjusted, the locking plate 12 is pushed to slide on the surface of the fixing bottom plate 1, when the specific position is reached, the limiting bolts 13 are rotated into the corresponding limiting holes 14, meanwhile, the movable bolts 16 are rotated to fix the sliding plates 15 in the inside the fixing bottom plate 1, and therefore the applicability of the fixator for adjusting the position of the locking plate 12 is improved, and the applicability of the fixator is enlarged.
It should be noted that the foregoing description is only a preferred embodiment of the present utility model, and although the present utility model has been described in detail with reference to the foregoing embodiments, it should be understood that modifications, equivalents, improvements and modifications to the technical solution described in the foregoing embodiments may occur to those skilled in the art, and all modifications, equivalents, and improvements are intended to be included within the spirit and principle of the present utility model.
