Description

Technical Field

[0001] This utility model relates to the field of machining fixture technology, and in particular to a positioning fixture for wire EDM machining of tie rods. Background Technology

[0002] Wire EDM is short for wire cutting, referring to a machining method. It was developed based on electrical discharge machining (EDM) for drilling and forming. It uses a moving metal wire (molybdenum wire, copper wire, or alloy wire) as an electrode wire. The pulsed electric spark discharge between the electrode wire and the workpiece generates high temperature, which melts or vaporizes the metal, forming a kerf, thereby cutting out the part. For example, it is used for cutting the round hole in a tie rod.

[0003] The current method for cutting round holes in tie rods requires positioning the tie rod. This typically involves fixing two positioning blocks and then placing the adjacent sides of the tie rod against these blocks. However, this method requires positioning the tie rod for each machining operation, making it cumbersome, inefficient, and prone to misalignment due to the lack of clamping or securing the tie rod during processing. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a positioning fixture for wire EDM of tie rods.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A positioning fixture for wire EDM of tie rods includes:

[0007] Base;

[0008] A through slot is provided on one side of the upper surface of the base;

[0009] A limiting block is provided at one end of the placement slot and is installed and connected to the side wall of the base;

[0010] A clamping structure is movably mounted on the base, wherein after the pull rod is inserted into the placement slot and presses against the limiting block, the clamping structure clamps and fixes the pull rod in the placement slot.

[0011] As described above, in a positioning fixture for wire EDM of a tie rod, the limiting block is detachably connected to the side wall of the base.

[0012] As described above, a positioning fixture for wire EDM of a tie rod has several connecting holes on the limiting block, and connecting screws that pass through the connecting holes and can be threaded onto the side wall of the base.

[0013] As described above, a positioning fixture for wire EDM of a tie rod includes a clamping structure comprising a top pressure rod extending through one side of the base. A pull block is connected to one end of the top pressure rod extending outward from the base, and the other end of the top pressure rod can extend into the placement slot. The base is also provided with an elastic top pressure structure that allows the top pressure rod to press against the placement slot.

[0014] As described above, a positioning fixture for wire EDM of a tie rod includes an elastic pressing structure comprising a pressing cavity formed in the base, one end of the pressing rod passing through the pressing cavity and extending into the placement slot, and a pressing plate slidably placed in the pressing cavity on the pressing rod, and an elastic pressing element connected between the pressing plate and the bottom wall of the pressing cavity.

[0015] As described above, in a positioning fixture for wire EDM of a tie rod, the elastic pressing element is a spring, with one end pressing against the pressing plate and the other end pressing against the bottom wall of the pressing cavity.

[0016] As described above, in a positioning fixture for wire EDM of a tie rod, the placement slot is arranged parallel to the length direction of the base.

[0017] As described above, a positioning fixture for wire EDM of a tie rod is provided with a push notch at the upper end of the limiting block.

[0018] The beneficial effects of this utility model are as follows: This application has a simple structure. By opening a placement slot on the base and setting a limiting block, the base is positioned and fixed during processing. Then, the pull rod is simply inserted into the placement slot and pressed against the limiting block to complete the positioning. There is no need to reposition the pull rod, which improves processing efficiency. Moreover, by setting a clamping structure, the pull rod can be clamped and fixed in the placement slot during processing to ensure that the pull rod is stable and does not deviate, thereby ensuring processing quality. It is practical and convenient. Attached Figure Description

[0023] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1 to 3 As shown in the figure, this application provides a positioning fixture for wire EDM machining of tie rods, including:

[0025] Base 1;

[0026] A through groove 2 is provided on one side of the upper surface of the base 1;

[0027] A limiting block 3 is disposed at one end of the placement slot 2 and installed on the side wall of the base 1;

[0028] The clamping structure 4 is movably mounted on the base 1. After the pull rod 100 is inserted into the placement slot 2 and presses against the limiting block 3, the clamping structure 4 clamps and fixes the pull rod 100 in the placement slot 2.

[0029] By opening a placement slot 2 on the base 1 and setting a limiting block 3, during processing, after the base 1 is positioned and fixed, the pull rod 100 can be simply inserted into the placement slot 2 and pressed against the limiting block 3 to complete the positioning. There is no need to reposition the pull rod 100, which improves processing efficiency. In addition, by setting a clamping structure 4, the pull rod 100 can be clamped and fixed in the placement slot 2 during processing to ensure that the pull rod 100 is stable and does not deviate, thereby ensuring processing quality. It is practical and convenient.

[0030] Furthermore, the limiting block 3 is detachably connected to the side wall of the base 1.

[0031] Specifically, the limiting block 3 is provided with a plurality of connecting holes 31 and connecting screws 32 that pass through the connecting holes 31 and can be threaded to the side wall of the base 1.

[0032] Furthermore, the clamping structure 4 includes a top pressure rod 41 that extends through one side of the base 1. A pull block 42 is connected to one end of the top pressure rod 41 that extends out of the outer side of the base 1. The other end of the top pressure rod 41 can extend into the placement slot 2. The base 1 is also provided with an elastic top pressure structure 5 that allows the top pressure rod 41 to press against the placement slot 2.

[0033] Specifically, the elastic pressing structure 5 includes a pressing cavity 51 opened in the base 1, one end of the pressing rod 41 passes through the pressing cavity 51 and extends into the placement groove 2, the pressing rod 41 is also provided with a pressing plate 52 slidably placed in the pressing cavity 51, and an elastic pressing member 53 is also connected between the pressing plate 52 and the bottom wall of the pressing cavity 51.

[0034] When clamping, pull the pull block 42, causing the top pressing rod 41 to move and sink into the base 1 (at this time, the elastic top pressing member 53 is compressed and stores force). Then, insert the pull rod 100 into the placement slot 2 and press it against the limit block 3. Then, release the pull block 42. During the recovery process, the elastic top pressing member 53 releases elastic potential energy, causing the top pressing rod 41 to move and press against the pull rod 100, thereby clamping and fixing the pull rod 100 in the placement slot 2. It is practical and convenient.

[0035] In this embodiment, the elastic pressing member 53 is a spring, with one end pressing against the pressing plate 52 and the other end pressing against the bottom wall of the pressing cavity 51.

[0036] Specifically, the placement slot 2 is arranged parallel to the length direction of the base 1. This facilitates processing and positioning.

[0037] Furthermore, the upper end of the limiting block 3 is also provided with a push notch 30. The push notch 30 facilitates the pushing of the processed pull rod 100 into the through slot 2, which is practical and convenient.

[0038] In summary, the embodiments of this application, by opening a placement groove 2 on the base 1 and cooperating with the setting of a limiting block 3, allow for easy positioning of the base 1 during processing. After positioning and fixing the base 1, the pull rod 100 can be simply inserted into the placement groove 2 and pressed against the limiting block 3 to complete the positioning without the need for repositioning the pull rod 100, thus improving processing efficiency. Furthermore, by providing a clamping structure 4, the pull rod 100 can be clamped and fixed in the placement groove 2 during processing, ensuring the stability of the pull rod 100 and preventing it from shifting, thereby guaranteeing processing quality. This approach is practical and convenient.
