Description

Technical Field

[0001] This utility model relates to the field of tooling technology for thin plate processing, and specifically to a high-efficiency tooling for drilling and positioning holes in thin plates. Background Technology

[0002] Tooling, also known as process equipment, refers to the general term for various tools used in the manufacturing process. This term is sometimes synonymous with tooling and sometimes refers to fixtures. Fixtures belong to tooling, and tooling includes fixtures, indicating a subordinate relationship. Fixtures are process devices used to quickly fasten workpieces during machining, ensuring that machine tools, cutting tools, and workpieces maintain the correct relative positions. Some existing machined sheet metal is too large and too thin, making it impossible to perform side drilling and tapping on machine tools. In addition, because positioning is inconvenient, operators are prone to deviation when manually drilling and tapping on the side.

[0003] To solve the above-mentioned technical problems, the prior art Chinese patent with publication number CN212351235U discloses a positioning tool for drilling and tapping thin plates, which relates to the field of processing tooling technology. The connector has a groove inside, and the inner wall of the groove is tightly fitted with a rubber pad. The top of the connector has a round opening, and a rotating core passes through the middle of the rotating block. The end of the rotating core is inserted into the round opening to measure the length and width of the plate.

[0004] While the existing technical solution described above is convenient for positioning and opening holes on the side of the thin plate, its ruler is made of metal. When pushing, a large force is required to push the magnetic block on its surface. However, the magnetic block can be attracted at various points on the ruler. If the pushing force is too large, it is easy to push too far. If the pushing force is too small, it will not be smooth and will feel resistant. It is impossible to make precise adjustments according to the actual needs of the personnel. Utility Model Content

A retraction groove is formed on one side of the outer wall of the extension plate 7. A retraction block 9 is slidably connected to the inner side of the retraction groove. Both the retraction groove and the retraction block 9 have T-shaped cross-sections. A first spring 10 is installed between the retraction block 9 and the inner wall of the retraction groove. An indicating plate 11 is installed at one end of the retraction block 9. The sliding block 6 and the sliding groove... A second spring is installed between the inner walls. First, when the staff measures the length and width of the thin plate, they can hold the sliding frame 5 and slide it on the surface of the ruler plate 3 in conjunction with the limiting block 4 and the limiting groove. After the indicator plate 11 moves to the specified data position on the ruler plate 3, the extension plate 7 can be pressed to make the pushing block 6 slide inside the pushing groove and drive the second spring to stretch, so that the pressing block 13 enters the pressing groove and contacts the inclined surface of the abutment block 14. At the same time, the groove engages with the restraint seat 15, forcing the abutment block 14 to squeeze the fourth spring to retract, and the restraint seat 15 squeezes the third spring to retract.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the positioning assembly includes a placement seat 12 installed on one end of the inner wall of the sliding frame 5. A pressing groove is provided on one side of the top of the placement seat 12, and a pressing block 13 is installed on the other end of the bottom of the extension plate 7. An abutment groove is provided inside the placement seat 12 on one side of the pressing groove. An abutment block 14 is slidably connected to the inside of the abutment groove. A fourth spring is installed between one side of the abutment block 14 and the inner wall of the abutment groove. Then, until the anti-disengagement groove is close to the abutment groove, the fourth spring can drive the abutment block 14 to pop out and lock into the inside of the anti-disengagement groove for positioning. At this time, the rubber pad 8 can press against the ruler plate 3. At this time, after the indicator plate 11 is pressed, it can drive the retraction block 9 to squeeze the first spring 10 to retract and avoid it inside the retraction groove. Then, after the assembly is completed, the indicated position of the indicator plate 11 can be observed to judge the data.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the inner wall of the abutment groove and the abutment block 14, the inside of the placement seat 12 has a binding groove on one side of the pressing groove, the binding seat 15 is slidably connected to the inner side of the binding groove, two sets of third springs are arranged and installed between one side of the binding seat 15 and the inner wall of the binding groove, the opposite ends of the abutment block 14 and the pressing block 13 are both provided with inclined surfaces, one side of the outer wall of the pressing block 13 is provided with an anti-detachment groove above the inclined surface, one end of the abutment block 14 is slidably connected to the anti-detachment groove, the bottom end of the pressing block 13 is provided with a groove, the groove is slidably connected to the binding seat 15, and the placement seat 12 is provided with a binding groove. A groove is provided on one side of the seat 12. A pull rod 16 is installed on the side where the seat 12 is placed. A torsion plate 17 is installed at the end of the pull rod 16 that extends to the outside of the groove. Furthermore, when it is necessary to unlock the indicator plate 11, the torsion plate 17 can be pinched to drive the pull rod 16 to slide inside the groove, so that the abutment block 14 is actively pulled away from the inside of the anti-detachment groove. At this time, the two sets of first springs 10 and second spring respectively drive the restraint seat 15 and the push block 6 to rise, bringing the rubber pad 8 away from the surface of the ruler plate 3 to complete the unlocking. Then the sliding frame 5 can be freely pushed to adjust the position.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a threaded hole is provided at the other end of the connecting frame body 1. A bolt 18 is threaded into the inner side of the threaded hole, and a rubber plug 19 is installed at the other end of the bolt 18. A through hole is provided on the other side of the outer wall of the connecting frame body 1. Furthermore, in conjunction with the rotating shaft 2, the ruler plate 3 can be rotated and adjusted. When assembling the thin plate, the edge of the thin plate can be inserted into the recess of the connecting frame body 1 for initial locking. Then, the bolt 18 is screwed in from the inner side of the threaded hole, so that the rubber plug 19 is pressed against the bottom end of the thin plate. At this time, the worker can drill holes in the side of the thin plate through the through hole on the connecting frame body 1.

[0027] The implementation principle of the high-efficiency thin plate drilling and positioning fixture in this application embodiment is as follows: When the worker measures the length and width of the thin plate, the sliding frame 5 can be held and slid on the surface of the ruler plate 3 in conjunction with the limiting block 4 and the limiting groove. After the indicator plate 11 moves to the specified data position on the ruler plate 3, the extension plate 7 can be pressed to make the pushing block 6 slide inside the pushing groove and drive the second spring to stretch, so that the pressing block 13 enters the pressing groove and contacts the inclined surface of the abutment block 14. At the same time, the groove engages with the restraint seat 15, forcing the abutment block 14 to squeeze the fourth spring to retract, and the restraint seat 15 squeezes the third spring to retract until the anti-disengagement groove is close to the abutment groove. The fourth spring can drive the abutment block 14 to pop out and lock into the anti-disengagement groove for positioning. At this time, the rubber pad 8 can press against the ruler plate 3. At this time, after the indicator plate 11 is pressed, it can drive the retraction block 9 to press the first spring inside the retraction groove. Spring 10 retracts to avoid obstruction. After assembly, the position indicated by indicator plate 11 can be observed to determine the data. When it is necessary to unlock indicator plate 11, pinch torsion plate 17 to drive pull rod 16 to slide inside the groove, so that abutment block 14 is actively pulled away from the anti-detachment groove. At this time, the two sets of first spring 10 and second spring respectively drive restraint seat 15 and push block 6 to rise, bringing rubber pad 8 away from the surface of ruler plate 3 to complete the unlocking. At this time, the sliding frame 5 can be freely pushed to adjust the position. With the help of rotating shaft 2, ruler plate 3 can be deflected and adjusted. When assembling thin plate, the edge of thin plate can be inserted into the recess of connecting frame body 1 for initial locking. Then, screw bolt 18 into the threaded hole so that rubber plug 19 is pressed against the bottom of thin plate. At this time, the worker can drill holes in the side of thin plate through the through hole on connecting frame body 1.
