Description

Technical Field

[0001] The utility model relates to the technical field of tapping jigs, in particular to an auxiliary jig for tapping sheet metal parts. Background Art

[0002] In the field of equipment manufacturing, the right-angle sheet metal part 1 shown in Figure 1 has important applications. It has a protruding bump structure b on one side and a tapping hole a on the other side that protrudes inward. It is mainly used for the installation and fixation of components such as sensors on the equipment. However, since sensors come in a variety of sizes and models, this type of sheet metal parts that are compatible with them have to be produced in many sizes and models during production and processing. Moreover, in order to meet the needs of a small-batch, multi-model production model, directional feeding devices such as vibrating plates that are limited to a single model of parts will not be applicable due to cost and other factors. In addition, the cost of the sheet metal part itself is relatively low, so the tapping process after punching out the sheet metal part usually adopts a combination of manual labor and semi-automatic tapping machines.

[0003] However, manual tapping has obvious drawbacks. Each operation can only tap one sheet metal part, which leads to a significant increase in cost and excessive time consumption. With the continuous increase in production demand, this inefficient tapping method can no longer meet the actual production schedule requirements. At the same time, multi-head tapping machine technology has made significant progress, and its tapping heads are increasingly flexible and adjustable. This provides a new opportunity to improve the tapping process of sheet metal parts. In view of the above situation, it is necessary to develop a new fixture that can achieve precise positioning of multiple sheet metal parts at the same time and can be perfectly applied to multi-head tapping machines, thereby realizing an efficient operation mode of tapping multiple sheet metal parts at a time. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0005] A sheet metal tapping auxiliary jig includes a sheet metal fixing jig and a jig fixing base for installation on a tapping machine. The sheet metal fixing jig is provided with a plurality of sheet metal fixing parts arranged in an array, each sheet metal fixing part is provided with a sheet metal insertion slot and a tapping positioning through hole, and a convex point giving portion is also provided in the sheet metal insertion through slot. Handles are provided on both sides of the sheet metal fixing jig, and pin positioning through holes are provided at the positions of the handles. A first pin piece is provided on the jig fixing base. The sheet metal fixing jig is positioned and placed on the jig fixing base through the cooperation between the pin positioning through hole and the first pin piece.

[0006] Preferably, a lifting support is further extended from the lower end of the sheet metal fixing jig, so that a space is formed below the sheet metal fixing jig for accommodating the sheet metal parts exposed along the sheet metal insertion grooves.

[0007] Preferably, the sheet metal tapping auxiliary jig also includes a sheet metal stripping base, on which a second pin member and an ejection portion for ejecting the sheet metal member are provided. The sheet metal fixing jig is positioned and placed on the sheet metal stripping base through the cooperation of the pin positioning through hole and the second pin member, so that the ejection portion can eject the sheet metal member from the sheet metal insertion slot at a fixed point.

[0008] Preferably, the ejection portion includes an abutting portion abutting against the lower end of the sheet metal fixing jig and a stripping portion capable of being inserted into the sheet metal insertion groove.

[0009] Preferably, a spring is sleeved on the second pin member, and the spring is used for elastically abutting and cooperating with the sheet metal fixing fixture.

[0010] Preferably, a plurality of convex strips are laterally distributed on the sheet metal fixing jig at intervals, at least one sheet metal fixing portion is formed between two adjacent convex strips, and the lifting support is arranged directly below the convex strips.

[0011] Preferably, two sheet metal fixing portions are formed between two adjacent convex strips.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The sheet metal fixing fixture is equipped with multiple sheet metal fixing parts arranged in an array, which can hold multiple sheet metal parts at the same time. Combined with a multi-head tapping machine, it can tap multiple sheet metal parts at a time. Compared with the traditional manual method of tapping only one sheet metal part at a time, it greatly improves the overall tapping efficiency and shortens the production cycle.

[0014] Each sheet metal fixing part is equipped with a precise tapping positioning through-hole, which provides an accurate positioning reference for the tapping head. In addition, the sheet metal parts can be accurately fixed through specific plug-in slots and raised point concessions, which effectively guarantees the accuracy of tapping and ensures that the produced sheet metal parts meet the quality requirements for installing components such as sensors.

[0015] When tapping sheet metal parts of different sizes, it can be achieved by simply replacing the sheet metal fixing fixture. Compared with directional feeding devices such as vibrating plates, designing fixtures of different sizes will greatly reduce costs.

[0016] The handles on both sides of the sheet metal fixing fixture make it easier for operators to carry and install the fixture, making it more convenient and efficient to install it in conjunction with the fixture fixing base, reducing installation time and labor costs. At the same time, the simple cooperation between the pin positioning through hole and the first pin member enables fast and accurate positioning and installation, further improving the convenience of operation.

DETAILED DESCRIPTION

[0025] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-4In an embodiment of the utility model, a sheet metal tapping auxiliary jig is proposed, including a sheet metal fixing jig 10 and a jig fixing base 20 for being installed on a tapping machine. The sheet metal fixing jig 10 is provided with a plurality of sheet metal fixing parts arranged in an array, each sheet metal fixing part is provided with a sheet metal insertion groove 11 and a tapping positioning through hole 12, and a convex point giving portion 13 is also provided in the sheet metal insertion through groove 11. Handle parts 14 are respectively provided on both sides of the sheet metal fixing jig 10, and pin positioning through holes 15 are provided at the position of the handle parts 14. A first pin part 21 is provided on the jig fixing base 20, and the sheet metal fixing jig 10 is positioned and placed on the jig fixing base 20 by cooperating with the pin positioning through hole 15 and the first pin part 21.

[0027] The sheet metal parts 1 that need to be tapped are placed on the sheet metal fixing parts arranged in a plurality of arrays on the sheet metal fixing jig 10. Each sheet metal part 1 is inserted into the sheet metal insertion slot 11 on the sheet metal fixing part by its own shape. If the sheet metal part 1 has a protruding point structure, it can be accommodated by the protruding point concession portion 13 to ensure that the sheet metal part 1 can be accurately placed in place. At the same time, the tapping positioning hole 12 provides an accurate positioning reference for the subsequent tapping operation. The sheet metal fixing jig 10 cooperates with the first pin member 21 of the jig fixing base 20 installed on the tapping machine through the pin positioning holes 15 opened at the handles 14 on both sides of the sheet metal fixing jig 10, thereby accurately positioning the sheet metal fixing jig 10 on the jig fixing base 20, so that the entire jig system forms a stable connection with the tapping machine, ready for the tapping operation. When the multi-head tapping machine is started, its flexibly adjustable tapping head performs tapping operations on multiple sheet metal parts 1 at the same time according to the position of the tapping positioning holes 12 of each sheet metal fixing part on the sheet metal fixing fixture 10. Since the sheet metal parts 1 have been accurately fixed in the early stage and the fixture and the tapping machine are accurately positioned, the accuracy and efficiency of tapping can be guaranteed.

[0028] The sheet metal fixing fixture 10 is provided with multiple sheet metal fixing parts arranged in an array, which can place multiple sheet metal parts 1 at the same time. In conjunction with a multi-head tapping machine, it can tap multiple sheet metal parts 1 at a time. Compared with the traditional manual method of tapping only one sheet metal part 1 at a time, it greatly improves the overall tapping efficiency and shortens the production cycle.

[0029] Each sheet metal fixing part is provided with a precise tapping positioning through hole 12, which provides an accurate positioning reference for the tapping head. In addition, the sheet metal part 1 can be accurately fixed through specific insert grooves and convex point paving parts 13 and other structures, which effectively guarantees the accuracy of tapping and ensures that the produced sheet metal part 1 meets the quality requirements for installing components such as sensors.

[0030] When tapping sheet metal parts 1 of different sizes, it can be achieved by simply replacing the sheet metal fixing fixture 10. Compared with devices that use directional feeding such as vibrating plates, designing fixtures of different sizes will greatly reduce costs.

[0031] The handles 14 provided on both sides of the sheet metal fixing jig 10 facilitate operators in carrying and installing the jig, making it more convenient and efficient in the installation process in conjunction with the jig fixing base 20, reducing installation time and labor costs. At the same time, through the simple cooperation between the pin positioning through hole 15 and the first pin member 21, fast and accurate positioning and installation are achieved, further improving the convenience of operation.

[0032] See also Figure 2 The present invention further proposes that the lower end of the sheet metal fixing jig 10 is also extended with a raised support 16, so that a space is formed below the sheet metal fixing jig 10 for the sheet metal part 1 to be exposed and accommodated along the sheet metal insertion slot 11. During the tapping operation, the operator can more clearly observe the placement of the sheet metal part 1 in the slot and the coordination between the tapping head and the tapping positioning hole 12. This helps to promptly detect possible problems such as displacement of the sheet metal part 1 and tapping deviation, so that measures can be taken quickly to ensure smooth tapping and tapping quality. In certain special circumstances, such as making minor adjustments to individual sheet metal parts 1 or temporarily intervening in the tapping process, the exposed space makes it convenient for the operator to insert tools or fingers, allowing them to perform necessary manual operations on the sheet metal part 1 without affecting the overall tapping operation, thereby improving the flexibility and controllability of the entire tapping process. In addition, metal debris is generated during the tapping process, and the space formed by the raised support 16 provides a channel for these debris to fall. The debris can naturally fall along the gap between the sheet metal part 1 and the through groove, avoiding the accumulation of debris at the bottom of the sheet metal fixing fixture 10, thereby reducing the interference of the debris on the tapping operation.

[0033] See also Figure 3-4The present utility model further proposes that the tapping auxiliary jig for the sheet metal part 1 also includes a sheet metal stripping base 30, on which a second pin part 31 and an ejection part 32 for ejecting the sheet metal part 1 are provided. The sheet metal fixing jig 10 is positioned on the sheet metal stripping base 30 by the cooperation of the pin positioning through-hole 15 and the second pin part 31, so that the ejection part 32 can eject the sheet metal part 1 from the sheet metal insertion slot 11 at a fixed point. After the tapping operation is completed, the pin positioning through-hole 15 of the sheet metal fixing jig 10 is precisely coordinated and positioned with the second pin part 31 on the sheet metal stripping base 30, so as to ensure that the ejection part 32 is accurately aligned with the position of each sheet metal part 1, thereby realizing the efficient and stable ejection of the sheet metal part 1 from the sheet metal insertion slot 11 at a fixed point, greatly improving the stripping efficiency and saving the time and energy of manually removing the sheet metal parts 1 one by one. This precise ejection method effectively prevents damage to the tapped sheet metal part 1 due to improper stripping operations, ensuring the quality and integrity of the sheet metal part 1, making it more suitable for the subsequent installation and fixation of components such as sensors on the equipment. Furthermore, the standardization and automation of the entire stripping process are improved, making the entire tapping production process smoother and more coherent, reducing possible jams or delays in the stripping process, further improving overall production efficiency, and meeting the needs of modern and efficient production.

[0034] See also Figure 3-4 The present invention further proposes that the ejection portion 32 includes an abutment portion 321 that abuts against the lower end of the sheet metal fixing fixture 10 and a stripping portion 322 that can be inserted into the sheet metal insertion slot 11. The abutment portion 321 abuts against the lower end of the sheet metal fixing fixture 10, providing a stable support force for the ejection action, ensuring that when the sheet metal part 1 is ejected from the sheet metal insertion slot 11, the entire ejection process is smooth and powerful, avoiding shaking, offset, etc. caused by unstable support, which may affect the ejection effect or cause unnecessary damage to the sheet metal part 1 and the fixture. The stripping portion 322 can be accurately inserted into the sheet metal insertion slot 11, and can achieve more precise contact with the sheet metal part 1, so that the ejection operation can act more directly and effectively on the sheet metal part 1, thereby efficiently ejecting it from the slot, which not only further improves the accuracy and success rate of stripping, but also can better adapt to sheet metal parts 1 of different sizes and shapes, ensuring that all types of sheet metal parts 1 can smoothly complete the stripping process, greatly improving the reliability and practicality of the entire sheet metal part 1 tapping auxiliary fixture in the stripping link.

[0035] See also Figure 3-4The present invention further proposes that a spring 33 is sleeved on the second pin member 31, and the spring 33 is used to elastically abut against the sheet metal fixing jig 10. When the sheet metal fixing jig 10 and the sheet metal stripping base 30 are positioned and installed, the spring 33 can play a buffering role, effectively absorbing the impact force that may be generated during the cooperation between the two, avoiding damage to the sheet metal fixing jig 10, the sheet metal stripping base 30 and related components due to hard collision, and extending the service life of each component. In the process of ejecting the sheet metal part 1, the elastic force of the spring 33 can assist in adjusting the ejection force, making the ejection action more stable and uniform, which can not only ensure that the sheet metal part 1 can be smoothly ejected from the sheet metal insertion slot 11, but also prevent the sheet metal part 1 from being damaged or flying out due to excessive ejection force, thereby improving the safety and reliability of the stripping operation.

[0036] See also Figure 2-4 The present invention further proposes that a plurality of ridges 17 arranged at intervals are distributed transversely on the sheet metal fixing jig 10, and at least one sheet metal fixing portion is formed between two adjacent ridges 17. Specifically, two sheet metal fixing portions or three sheet metal fixing portions are formed between two adjacent ridges 17, and the lifting support 16 is arranged directly below the ridges 17. The layout of the multiple ridges 17 and the multiple sheet metal fixing portions formed enables more sheet metal parts 1 to be placed more reasonably and efficiently within a limited space, further increasing the number of sheet metal parts 1 that can be tapped simultaneously at one time, and greatly improving the overall efficiency of the tapping operation. The arrangement of two or three sheet metal fixing portions formed between two adjacent ridges 17 enhances the standardization and regularity of the layout, facilitates the operator to accurately and quickly place and position the sheet metal parts 1, reduces the probability of operational errors, and is also conducive to the subsequent unified management and processing flow arrangement of multiple sheet metal parts 1. The raised support 16 is located directly below the ridges 17. On the one hand, it can provide more stable support for the sheet metal 1 placed in a fixed position between the ridges 17, ensuring the position stability of the sheet metal 1 during the tapping process and guaranteeing the tapping accuracy; on the other hand, when debris is generated by tapping, the space below allows the debris to fall more smoothly from the gaps between adjacent ridges 17, which is more conducive to chip removal and cleaning, keeps the working environment clean, and reduces the interference of debris on the tapping operation, thereby further improving the practicality and reliability of the entire sheet metal 1 tapping auxiliary jig.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
