Description

Technical Field

[0001] This utility model relates to the field of spring manufacturing technology, and in particular to a cutting fixture for the production of small-sized probe springs. Background Technology

[0002] Springs are typically manufactured using spring coiling machines for automated coiling and cutting. However, the springs used in probes are relatively small, with a spring diameter of 0.55mm, wire diameter of 0.1mm, spacing of 0.2mm, and a standard length of 9 coils. Due to these size limitations, cutting on a spring coiling machine is difficult, inaccurate, and prone to damaging the springs. Therefore, our company improved the production process by first using a spring coiling machine to coil the springs, and then cutting the coiled semi-finished products to complete the production of small-sized probe springs. To ensure smooth spring cutting, a manual cutting fixture was developed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a manual cutting fixture for producing probe springs.

[0004] To solve the above-mentioned technical problems, the present invention provides a cutting fixture for producing small-sized probe springs, comprising a base plate, a limiting plate, and cutting scissors. The limiting plate is detachably stacked on the base plate. The limiting plate has a limiting groove for embedding the spring, with one end closed and the other end open and extending to the edge of the limiting plate. The closed end of the limiting plate has a cutting groove for the cutting scissors to extend into. The cutting groove is perpendicular to the limiting groove. The distance between the cutting groove and the closed end of the limiting groove is the same as the length of the probe spring. The diameter of the limiting groove matches the diameter of the probe spring, and the diameter of the cutting groove matches the thickness of the cutting scissors. One end of the cutting scissors has a blade, and the other end of the cutting scissors opposite the blade is embedded in a handle.

[0005] Furthermore, the base plate and the limiting plate are made of iron, steel or stainless steel.

[0006] Furthermore, the handle is made of hard plastic and has anti-slip textures on the outside.

[0007] Furthermore, there are at least two limiting through slots, which are parallel to each other and perpendicular to the cutting through slot.

[0008] The beneficial effects of the utility model are:

[0009] 1. This application uses a base plate, a limiting plate, and a cutting shears to cooperate so that the limiting through groove and the cutting through hole on the limiting plate form a limiting groove and a cutting groove with the cooperation of the base plate, thereby realizing the limiting and cutting operation of the spring. Since the distance between the cutting groove and the closed end of the limiting through groove is the same as the length of the probe spring, the yield of the cut probe spring is high, and the operation is simple, convenient and quick.

[0010] 2. The base plate and the limiting plate in this application are detachable and stackable, and are made of metal, which makes them simple to manufacture and easy to use metal plate scraps, thus reducing costs.

[0011] 3. In this application, the diameter of the limiting through groove matches the diameter of the probe spring, and the diameter of the cutting through groove matches the thickness of the cutting shears, to prevent the spring and cutting shears from shaking after insertion, affecting the cutting quality and reducing the yield of probe springs.

[0012] 4. The handle in this application is made of hard plastic and has anti-slip texture on the outside to facilitate cutting operations. The cutting blade is embedded in the handle, and when the blade of the cutting blade becomes dull, a new cutting blade can be replaced, realizing the reuse of the handle. The cutting blade is preferably a utility knife blade.

[0013] 5. In this application, multiple parallel limiting slots can be set on the limiting plate to enable multiple springs to be cut at one time, thereby improving work efficiency.

[0023] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information. Example 1

[0024] like Figure 1-Figure 3 As shown, a cutting fixture for producing small-sized probe springs includes a base plate 1, a limiting plate 2, and a cutting shear 3. The limiting plate 2 is detachably stacked on the base plate 1. The limiting plate 2 is provided with a limiting groove 4 into which spring A is embedded. One end of the limiting groove 4 is closed, and the other end is open and extends to the edge of the limiting plate 2. The closed end of the limiting plate 2 is provided with a cutting groove 5 for the cutting shear 3 to enter. The cutting groove is perpendicular to the limiting groove 4. The distance between the cutting groove and the closed end of the limiting groove 4 is the same as the length of the probe spring A. The diameter of the limiting groove 4 matches the diameter of the probe spring A, and the diameter of the cutting groove 5 matches the thickness of the cutting shear 3. One end of the cutting shear 3 is provided with a blade 6, and the other end of the cutting shear 3 opposite to the blade 6... The handle 7 is embedded within the base plate 1 and the limiting plate 2 are detachably stacked. The base plate 1 blocks one side of the limiting through groove 4 and the cutting through groove 5 on the limiting plate 2, so that the limiting through groove 4 and the cutting through hole on the limiting plate 2 form a limiting groove and a cutting groove with the cooperation of the base plate 1, thereby realizing the limiting and cutting operation of the spring A. Since the distance between the cutting groove and the closed end of the limiting through groove 4 is the same as the length of the probe spring A, the cut probe spring A meets the standard, and the operation is simple, convenient and quick. The diameter of the limiting through groove 4 matches the diameter of the probe spring A, and the diameter of the cutting through groove 5 matches the thickness of the cutting scissors 3, preventing the spring A from shaking after being put in and the cutting scissors 3 is put in, affecting the cutting quality and reducing the yield of probe spring A.

[0025] The base plate 1 and the limiting plate 2 are made of iron, steel or stainless steel, and the cutting shears 3 are preferably utility knife blades. The base plate 1 and the limiting plate 2 are made of metal, which is simple to manufacture and easy to make using metal plate scraps, thus reducing costs. Utility knife blades do not need to be made and can be used directly. At the same time, it is not necessary to specially make the base plate 1. Any metal plate can be used to replace the base plate 1 in this application, which is simple to operate and convenient to use. Example 2

[0026] like Figure 1-2 As shown, this embodiment is obtained by adding anti-slip texture 8 and other technical features based on embodiment one. The remaining technical features are the same as those in embodiment one, and the similarities will not be repeated here. The difference between this embodiment and embodiment one is that the handle 7 is made of hard plastic and has anti-slip texture 8 on the outside.

[0027] In this embodiment, the handle 7 is made of hard plastic, which provides protection during the cutting operation, and the outer side is provided with anti-slip texture 8 to facilitate the cutting operation. The cutting knife is embedded in the handle 7, and when the blade 6 of the cutting scissors 3 becomes dull, a new cutting scissors 3 can be replaced, realizing the reuse of the handle 7. At the same time, it is even possible to wrap the utility knife blade with tape to replace the handle 7 in this application, using readily available materials and further reducing the difficulty of use. Example 3

[0028] This embodiment is obtained by adding the number of technical features such as limiting through groove 4 on the basis of embodiment 2. The remaining technical features are the same as those in embodiment 2. The similarities will not be repeated here. The difference between this embodiment and embodiment 2 is that there are at least two limiting through grooves 4. The limiting through grooves 4 are parallel to each other and are all perpendicular to the cutting through groove 5.

[0029] In this embodiment, multiple parallel limiting slots 4 can be provided on the limiting plate 2 to enable multiple springs A to be cut at one time, thereby improving work efficiency.

[0030] The process of using the overall technical solution formed by the above embodiment is as follows: Place the limiting plate 2 on the base plate 1. The base plate 1 seals one side of the limiting through groove 4 and the cutting through groove 5 of the limiting plate 2 to form the limiting groove and the cutting groove. Hold the spring A with one hand and put the spring A into the limiting groove, so that one end of the spring A is against the closed end of the limiting through groove 4, and ensure that the spring A does not bend or deform upward. Press the spring A and the limiting through groove 4 with your hand to press and fix the limiting plate 2 and the spring A on the base plate 1. Hold the handle 7 with the other hand and insert the blade 6 of the cutting knife into the cutting groove and press down to complete the cutting of the spring A. The cut spring A is the probe spring A.

[0031] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention.
