Description

Technical Field

[0001] The invention relates to the technical field of parts fixtures, and in particular to a fixture used for 360-degree rotation setting of electric sparks and a use method thereof. Background Art

[0002] In the field of electrical discharge machining (EDM), precision manufacturing of parts has always been a technical challenge, especially for parts that require multi-sided machining. In the traditional machining process, most of the key parts such as the front and both sides of the parts need to be completed by electrical discharge machining. In this process, the front of the part is usually processed first to ensure that it meets the design requirements. However, after the front machining is completed, the operator needs to remove the part from the magnetic platform and perform secondary settings in order to process the other side of the part.

[0003] This secondary setting process is not only cumbersome, but also very easy to introduce errors. After completing the second processing, the part often needs to be turned sideways for the third or even fourth setting process. Each clamping and repositioning means the consumption of time and resources. More importantly, multiple setting and positioning operations will inevitably lead to deviations in the setting position. After multiple accumulations, this deviation is likely to cause relative size differences of the parts, seriously affecting the processing accuracy of the parts.

[0004] Therefore, when facing parts that need multi-sided processing, traditional EDM methods are not only inefficient, but also difficult to ensure processing quality. Once a relative size difference occurs, the parts often need to be repaired or even directly scrapped, which undoubtedly increases manufacturing costs and reduces production efficiency. Summary of the invention

[0005] The object of the present invention is to provide a fixture for 360-degree rotation setting of electric sparks and a method for using the fixture to solve the problem of relative size deviation caused by multiple clamping settings of parts during the existing EDM processing.

DETAILED DESCRIPTION

[0016] The technical solution of the present invention is described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0017] Please refer to Figure 1-2 The present invention provides a fixture for 360-degree rotation setting of electric sparks. The fixture is exquisitely designed and can realize multiple angle fixation of the parts to be processed within a 360-degree range, thereby meeting the needs of multi-faceted processing of parts in electric spark processing. The specific structure of the fixture and its use method will be described in detail below.

[0018] The clamp is mainly composed of a reference base 1, a support rod 2 and a clamping assembly 3. The reference base 1 is the reference part of the entire clamp and can ensure the stability of the clamp during operation. Two base pin holes 11 are provided on the top of the reference base 1. The two base pin holes 11 are respectively a first base pin hole 111 and a second base pin hole 112. Their positions are relatively fixed and are used to cooperate with the positioning pin hole 21 on the support rod 2 to fix the support rod 2.

[0019] like Figure 3 As shown, the support rod 2 is a key component connecting the reference seat 1 and the clamping assembly 3. Two mutually perpendicular positioning pin holes 21 are provided on the rod body of the support rod 2, and the two positioning pin holes 21 are respectively a first positioning pin hole 211 and a second positioning pin hole 212. When the support rod 2 needs to be fixed, it can be achieved by inserting the pull pin 4 into the corresponding base pin hole 11 and the positioning pin hole 21. This design allows the support rod 2 to rotate at multiple angles within a range of 360 degrees, and through the fixing effect of the pull pin 4, the stability of the support rod 2 during the processing is ensured.

[0020] In addition, the front end of the support rod 2 is provided with a mounting block 22, which is used to cooperate with the mounting seat 36 in the clamping assembly 3, so as to realize the detachable connection between the clamping assembly 3 and the support rod 2. This connection mode is not only convenient for the replacement and maintenance of the clamping assembly 3, but also can ensure the stability of the clamping assembly 3 during operation. The rear end of the support rod 2 is provided with a hexagonal hole 23, and the design of the hexagonal hole 23 is convenient for rotating the support rod 2 using tools such as a wrench.

[0021] Reference Figure 4-6The clamping assembly 3 is the part of the fixture used to clamp the parts to be processed. The clamping assembly 3 includes a clamping seat 31 installed at the end of the support rod 2, and a space for placing the parts to be processed is provided on the clamping seat 31. In order to ensure the stability of the parts to be processed during the processing, a clamping groove 32 is provided at the outer end of the clamping seat 31, and a detachable slide buckle 33 is provided in the clamping groove 32. The design of the slide buckle 33 enables the clamping assembly 3 to adapt to parts to be processed of different sizes, thereby improving the versatility and flexibility of the fixture.

[0022] A clamping groove bar 34 is provided at the bottom of the clamping groove 32, and a screw 35 is provided on the clamping groove bar 34. The screw 35 is threadedly connected to the slider 33, and the position of the slider 33 in the clamping groove 32 can be adjusted by rotating the screw 35, thereby achieving the clamping or loosening operation of the workpiece to be processed. This design is not only convenient for operation, but also can ensure the stability of the workpiece to be processed during the processing.

[0023] When using the fixture for EDM, you first need to install and debug the fixture according to the following steps: Step S1: Place the fixture on the magnetic platform. The design of the magnetic platform can ensure the stability of the fixture during the working process. When placing the fixture, it is necessary to adjust the X direction of the fixture to be parallel to the travel direction of the working head, and the Y direction of the fixture to form a 90-degree vertical relationship with the working head. This adjustment method can ensure that during the processing, the working head can accurately move along the preset processing path.

[0024] Step S2: Manually loosen the screw 35 on the clamp head clamp seat 31. After loosening the screw 35, the clamping assembly 3 can be rotated to fix the part to be processed on the clamp. When fixing the part to be processed, it is necessary to ensure that the position of the part is accurate and stable to avoid deviation or shaking during the processing.

[0025] Step S3: Insert the pull pin 4 into the first base pin hole 111 and the first positioning pin hole 211 to fix the support rod 2. When inserting the pull pin 4, it is necessary to ensure that the pull pin 4 is fully inserted into the hole to achieve a stable fixation of the support rod 2. The fixed support rod 2 can ensure that it will not rotate or shake during the processing, thereby ensuring the processing accuracy and stability.

[0026] Next, the automatic positioning and first discharge machining of the EDM are carried out: Step S4: Start the discharge machine to perform automatic positioning operation. Automatic positioning operation is an important step in EDM, which can set the processing point on the part according to the preset processing parameters to prepare for formal processing. During the automatic positioning process, it is necessary to ensure that the discharge machine is in normal working condition and can accurately identify the position and shape of the part to be processed.

[0027] Step S5: Start the first EDM at the set processing point. The purpose of the first EDM is to form an initial processing mark on the part to be processed, which provides a reference for subsequent processing. During the processing, it is necessary to pay close attention to the working status and processing effect of the EDM machine to ensure the processing quality and accuracy.

[0028] After the first EDM is completed, the support rod 2 needs to be rotated and fixed to facilitate the next side machining: Step S6: Manually loosen and pull out the pin 4 inserted into the first base pin hole 111. After pulling out the pin 4, the support rod 2 can be rotated. In this embodiment, the support rod 2 is rotated 90 degrees to process the next side. When rotating the support rod 2, it is necessary to ensure that the rotation angle is accurate and stable to avoid deviation during the processing.

[0029] Supplement to step S6: Subsequently, the pull pin 4 is inserted into the second base pin hole 112 and the second positioning pin hole 212 to fix the support rod 2 again. When inserting the pull pin 4, it is also necessary to ensure that the pull pin 4 is fully inserted into the hole to achieve a stable fixation of the support rod 2. The fixed support rod 2 can ensure that it will not rotate or shake during the processing of the next side.

[0030] Start the EDM machine at the new machining position for the second EDM: Step S7: Start the discharge machine at the new processing position to perform the second discharge processing. The purpose of the second discharge processing is to form a processing mark on the other side of the part to be processed. During the processing, it is also necessary to pay close attention to the working state and processing effect of the discharge machine to ensure the processing quality and accuracy. After the processing is completed, the pull pin 4 is manually pulled out again to process the next side.

[0031] In order to complete all surface machining of the parts to be machined, a third EDM is required: Step S8: Rotate the support rod 2 180 degrees counterclockwise. In this embodiment, since the processing of two adjacent surfaces has been completed, the support rod 2 needs to be rotated 180 degrees counterclockwise to process the remaining two surfaces. When rotating the support rod 2, it is also necessary to ensure that the rotation angle is accurate and stable.

[0032] Supplement to step S8: Insert the pin 4 into the second base pin hole 112 again to fix the support rod 2. When inserting the pin 4, it is necessary to ensure that the pin 4 is fully inserted into the hole and check its stability. The fixed support rod 2 can ensure that it will not rotate or shake during the processing of the remaining two surfaces.

[0033] Further supplement of step S8: set the third processing point according to the processing requirements, and process the last side. When setting the processing point, it is necessary to consider the shape and size of the part to be processed and the processing requirements to ensure the accuracy and rationality of the processing point. During the processing, it is also necessary to pay close attention to the working state and processing effect of the discharge machine to ensure the processing quality and accuracy. After the processing is completed, the pin 4 can be pulled out and the screw 35 can be loosened to remove the processed part.

[0034] In addition, in order to ensure the use effect and processing accuracy of the fixture, the following points should be noted during use: First of all, it is necessary to regularly check whether the various parts of the fixture are intact and tightly connected. If any parts are found to be damaged or loose, they need to be replaced or tightened in time to avoid affecting the processing quality and accuracy.

[0035] Secondly, when clamping the part to be processed, it is necessary to ensure that the position of the part is accurate and stable. The clamping or loosening operation of the part to be processed can be achieved by adjusting the slider 33 and the screw 35 in the clamping assembly 3 to ensure the stability of the part during the processing.

[0036] Finally, during the processing, it is necessary to pay close attention to the working status and processing effect of the discharge machine. If any abnormality is found or the processing quality does not meet the requirements, it is necessary to stop the machine in time to check and adjust the processing parameters or the position and angle of the fixture to ensure the normal progress of subsequent processing and the stability of processing quality.

[0037] In summary, the clamp for 360-degree rotation setting of electric spark provided in this embodiment has the advantages of compact structure, easy operation, strong versatility, etc. By adjusting the rotation angle of the support rod 2 and the position and angle of the clamping assembly 3, the parts to be processed can be fixed and processed at any angle within a 360-degree range. The clamp not only improves the efficiency and accuracy of electric spark processing, but also reduces the labor intensity and time cost of operators, and has broad application prospects and market value.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
