Description

Workbench fixture locator

This creation refers to a fixture positioner for a workbench, especially a technical field that can improve the position of a fixture that is indeed positioned on a workbench.

According to the conventional workbench, a screw hole is provided, so that the fixture of the workpiece can be screwed into the screw hole, but after a long time of use, the thread in the screw hole is gradually lost and smoothed, so that the screw hole can no longer be used. used.

In the case, the manufacturer changed the screw hole of the workbench into a type of the hole without the internal thread, and the positioner for positioning the jig is as shown in the first figure, which mainly consists of a positioning rod 10 and a limit. The ring 20 and an adjusting component 30 are formed. The positioning rod 10 has a threaded hole 101 in the straight direction (as shown in the second figure), and the lower side of the positioning rod 10 is provided with the same level of the same level that is connected to the internally threaded hole 101. The through hole 102, the bottom end of the internally threaded hole 101 is provided with a push ball 103, and each of the through holes 102 is provided with a ball 104, and the push ball 103 is moved downward to move the ball 104 to the partial forcing hole 102 (such as the third figure). The limit ring 20 is horizontally formed above the positioning rod 10. In addition, the adjusting member 30 has a rotating ring 301 and a downwardly extending through rod 302. The through rod 302 passes through the limiting ring 20 and downward. When the threaded hole 101 is screwed into the positioning rod 10, and the threaded rod 302 is screwed down, the push ball 103 can be forced to force the portion of the ball 104 out of the positioning rod 10 (as shown in the third figure).

According to the above, when the adjusting member 30 has not been screwed in, the positioning rod 10 is inserted into the group hole 501 of the table 50 through the jig 40, and then the downward adjustment is performed. The element 30 is such that the upper edge of the abutting ball 104 below the positioning rod 10 can abut against the underside of the table 50 (as shown in the fourth figure), and continues to be screwed downward into the adjusting element 30 to bring the lower side of the limiting ring 20 to the lower side. It is attached to the upper surface of the jig 40. However, since the thickness of the table 50 is not completely the same, even if the adjusting member 30 is screwed down again, the portion of the ball 104 is forced out of the positioning rod 10. The maximum limit, please refer to the fifth figure, and the adjusting element 30 can no longer be screwed down. At this time, the distance between the lower side of the limiting ring 20 and the upper edge of the abutting ball 104 is fixed, therefore, if The thickness of the table 50 is relatively thin, so that there is a gap S between the lower side of the limit ring 20 and the upper portion of the jig 40, and the state cannot be maintained in a horizontally tight state. Therefore, the jig 40 cannot be confirmed. Positioning, this will affect the displacement of the workpiece when it is processed, resulting in poor efficiency and yield. The same previous case creation is another example of China Patent Publication No. 201521950.

Therefore, it is necessary to provide a novel and progressive workbench fixture locator to solve the above-mentioned problems.

In view of the above, it can be seen that the technical problem to be solved in the present case is that the prior art jig locator has a defect that the top of the jig can no longer be rotated and the jig is not positioned accurately, and an effective technical solution is provided.

The technical solution adopted in the present invention to solve the above technical problem is to create a fixture locator for a workbench, which comprises at least a positioning rod, a limiting ring and an adjusting component, the positioning rod has a threaded hole in a straight direction, and The lower side of the positioning rod is provided with the same level of multiple perforations, and the perforations are all connected to the internally threaded holes, and the limiting ring is horizontally disposed on the positioning rod, and the adjusting element has a rotating ring, and the rotating ring extends downwardly and through. a rod, which is screwed down into the threaded hole of the positioning rod, And the lower end of the rod is provided with a plurality of abutting balls corresponding to the perforations, and when the rod is screwed down, the part of the ball can be forced out of the positioning rod; and the main improvement is that the limiting ring is sleeved In the positioning rod, the positioning rod is further provided with an externally threaded section above the limiting ring, and is assembled to the externally threaded section by a locking element. According to this, the locking element can be further screwed down into the limiting ring, so that the jig can be reliably positioned to overcome the lack of thickness inconsistency of the table.

Secondly, the positioning rod has a body section, and the external thread section is located above the body section, and the limiting ring is horizontally sleeved between the body section and the external thread section.

In addition, the perforation of the positioning rod is wide inside and narrow inside. Moreover, the positioning rod is provided with a concave ring above the external thread segment, and the concave ring is provided with a C-shaped ring.

Therefore, it can be seen that the purpose of the present invention is to provide a fixture locator for a workbench, which is mainly provided with a locking element by pivoting over the limit ring of the positioning rod, and the locking element can be further used to lower the limit. The bit ring allows the jig to be positioned above the table with a positive lock, and the inconsistency in the thickness of the table can be eliminated, resulting in an inaccurate positioning of the jig.

As shown in the sixth figure, a fixture positioner according to an embodiment of the present invention is shown, which comprises a positioning rod 1, a limiting ring 2, a locking element 3 and an adjusting element 4. Wherein (such as the seventh and eighth figures): the positioning rod 1, the main body is presented as a main body section 11, the main body section 11 has an externally threaded section 12 above, and the positioning rod 1 has a straight threaded hole 13 and below The side is provided with the same level of the plurality of perforations 14 , the perforations 14 are wide inside and the outside is narrow, and the perforations 14 are both connected to the internally threaded holes 13 , and the bottom end of the internally threaded holes 13 is closed by a bottom block 15 , in addition, A push ball 16 is disposed at a bottom end of the threaded hole 13 of the positioning rod 1, and a ball 17 is disposed in each of the through holes 14, and the push ball 16 is moved downward to move the ball 17 to a portion of the punched hole 14 (such as the eighth Figure). Furthermore, the positioning rod 1 is provided with a concave ring 18 above the externally threaded section 12, and the concave ring 18 is further provided with a C-shaped ring 19.

The limiting ring 2 is horizontally sleeved on the positioning rod 1 between the main body section 11 and the externally threaded section 12.

The locking element 3 is assembled on the threaded section 12 outside the positioning rod 1 and can be helically displaced up and down (also as shown in the ninth figure). When it is screwed down, it can be pressed down against the limiting ring 2 to make The limit ring 2 is displaced downward.

The adjusting member 4 has a rotating ring 41. The rotating ring 41 extends downwardly through a through rod 42. The through rod 42 is screwed downward into the internally threaded hole 13 of the positioning rod 1, and the lower end of the threaded rod 42 can be pushed down. When the ball 16 is pushed, and when the rod 42 is screwed down, the ball 16 can be pushed down to force the portion of the ball 17 to be forced out of the positioning rod 1 (as shown in Figs. 8 and 9).

When the adjusting element 4 has not been screwed in, the adjusting rod 4 is inserted into the group hole 61 of the table 6 through the jig 5, and then can be screwed down into the adjusting member 4 (as shown in the ninth figure). The lower side of the limiting ring 2 and the upper edge of the abutting ball 17 respectively abut against the upper surface of the jig 5 and the lower surface of the table 6. At this time, the force can be further applied downwardly into the locking element 3, and the lock is locked. The cymbal element 3 is pressed down against the limit ring 2 again, so that the limit ring 2 has a downward force to be pressed against the jig 5, so that the jig 5 can be positioned above or on the side of the table 6. (The figure is positioned above as an example), so that even if the thickness of the table 6 is not exactly the same (please compare the ninth and tenth figures), the lock element 3 is pressed down to the limit ring 2, It is possible to maintain a tight state between the upper part of each jig 5 and the lower side of the corresponding limit ring 2, and the jig 5 is positioned correctly, which is the main creative essence of the creation.

According to the above structural composition and implementation description, it can be seen that the external thread section 12 and the locking element 3 are added to the creation, so that the limiting ring 2 can be further rotated downward so that the jig 5 is reliably positioned to overcome the inconsistency of the thickness of the table 6. The lack of this, so that the workpiece will be processed without displacement, so the existing drawbacks can be completely eliminated, and work efficiency and yield can be improved.

In summary, when the knowledge of the creation has indeed been industrially useful, novel and progressive, in line with the new patent requirements.
