Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a stress relief tool for lathe cutting metal parts. Background Technology

[0002] In the metal processing system, lathe cutting is the core process. While giving metal workpieces precise geometry and dimensions, it inevitably introduces complex and concentrated residual stresses into them.

[0003] The long-term existence of these internal stresses acts like a potential source of defects within the workpiece. Over time, they can easily induce failure modes such as workpiece deformation and crack initiation, significantly negatively impacting its dimensional accuracy and service performance, and consequently drastically shortening the workpiece's expected service life. To address this common and critical problem in the field of metal processing, we propose a stress-relieving fixture for lathe-cut metal parts. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stress-relieving fixture for lathe-cut metal parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A stress-relieving fixture for cutting metal parts on a lathe includes a lathe. The upper side of the lathe is provided with a first stress-relieving mechanism, a clamping mechanism, and a second stress-relieving mechanism. The first stress-relieving mechanism includes a support plate. A high-frequency vibration motor is screwed to the bottom of the support plate. Structural connecting columns are symmetrically arranged on both sides of the bottom of the support plate. A groove is movably mounted at the lower end of each structural connecting column. Several springs are fixedly connected between the inner side of the groove and the lower end of the structural connecting column. Limiting holes are symmetrically opened on the sidewalls of the structural connecting columns. Ears are symmetrically fixedly mounted on the upper side of the groove. An electric telescopic rod is fixedly mounted on the sidewall of the ear. The output end of the electric telescopic rod passes through the inner side of the ear, and a limiting block adapted to the limiting holes is fixedly mounted on the output end of the electric telescopic rod.

[0007] Furthermore, a structural folding plate is fixedly installed on the upper side of the lathe, and a controller is fixedly installed on the back side of the structural folding plate.

[0008] Furthermore, the second stress relief mechanism includes an air pump, an air inlet pipe is fixedly connected to the air inlet end of the air pump, an air delivery pipe is fixedly connected to the air outlet end of the air pump, a transverse pipe is connected to the end of the air delivery pipe, and a plurality of air jet folds are equidistantly connected to the lower end of the transverse pipe, and the air delivery pipe passes through to the inside of the structural fold plate.

[0009] Furthermore, a dust filter screen is fitted onto the end of the air intake pipe.

[0010] Furthermore, an upper top plate is fixedly installed on the upper end of the structural connecting column, the upper top plate is screwed to the bottom of the support plate, and a chassis seat is fixedly installed at the bottom of the groove, the chassis seat is screwed to the upper side of the lathe.

[0011] Furthermore, a shock-absorbing pad is provided at the bottom of the chassis base.

[0012] Furthermore, the clamping mechanism includes symmetrically arranged arc plates, two of which are slidably disposed on the upper side of the support plate. A clamping pad is fixedly installed on the inner side of the arc plate. An electric push rod is symmetrically fixedly installed on the upper side of the support plate.

[0014] Compared with related technologies, the stress relief fixture for lathe cutting metal parts proposed in this utility model has the following beneficial effects:

[0015] In this utility model, a stress-relieving fixture for lathe-cut metal parts is described. It includes a first stress-relieving mechanism and a second stress-relieving mechanism. The first mechanism utilizes a high-frequency vibration motor to drive the metal part on the support plate to vibrate at high frequency. The resulting mechanical vibration causes minute displacements of atoms within the metal, accelerating the release of internal stress. The optimized combination of vibration frequency and amplitude can be adjusted according to the material, size, and shape of different metal parts to achieve the best stress-relieving effect. In the second stress-relieving mechanism, activating an air pump allows the air jet nozzle to spray air onto the metal part for cooling, slowly cooling the metal part to prevent the generation of new internal stress. The combined effect of the first and second stress-relieving mechanisms improves the elimination of internal stress in the metal part, preventing potential defects within the workpiece from easily inducing workpiece deformation, crack initiation, and other failure modes.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1-6 A stress-relieving fixture for cutting metal parts on a lathe includes a lathe 1, a first stress-relieving mechanism 2, a clamping mechanism 3, and a second stress-relieving mechanism 6 on the upper side of the lathe 1; the first stress-relieving mechanism 2 includes a support plate 21, a high-frequency vibration motor 22 is screwed to the bottom of the support plate 21, structural connecting columns 23 are symmetrically arranged on both sides of the bottom of the support plate 21, a groove 29 is movably mounted on the lower end of the structural connecting column 23, a plurality of springs 212 are fixedly connected between the inner side of the groove 29 and the lower end of the structural connecting column 23, limit holes 25 are symmetrically opened on the side wall of the structural connecting column 23, ear seats 26 are symmetrically fixedly installed on the upper side of the groove 29, an electric telescopic rod 27 is fixedly installed on the side wall of the ear seat 26, the output end of the electric telescopic rod 27 passes through to the inner side of the ear seat 26, and a limit block 28 adapted to the limit hole 25 is fixedly installed on the output end of the electric telescopic rod 27.

[0025] With the above-described setup, when clamping and machining the cutting metal part 4, the electric telescopic rod 27 needs to be activated to insert the limiting block 28 into the limiting insertion hole 25 inside the structural connecting column 23. This allows the lower end of the structural connecting column 23 to form an effective fixed engagement with the groove 29, enabling the support plate 21 to provide stable support. After the cutting process is completed, the electric telescopic rod 27 is activated to retract, causing the limiting block 28 to exit the engagement range with the limiting insertion hole 25. This allows the lower end of the structural connecting column 23 to have sliding freedom between the groove 29. Then, with the cooperation of the spring 212 and the action of the high-frequency vibration motor 22, the support plate 21 drives the upper clamped cutting metal part 4 to vibrate at high frequency. At this time, the vibration attenuation at the lower end of the structural connecting column 23 is reduced, which helps to eliminate the stress of the upper cutting metal part 4.

[0026] In this method, an upper top plate 24 is fixedly installed on the upper end of the structural connecting column 23. The upper top plate 24 is screwed to the bottom of the support plate 21. A chassis seat 210 is fixedly installed at the bottom of the groove 29. The chassis seat 210 is screwed to the upper side of the lathe 1. A shock-absorbing pad 211 is placed at the bottom of the chassis seat 210.

[0027] By setting it in the above manner, the vibration damping pad 211 can reduce the transmission of vibration to the upper side of the lathe 1.

[0028] In this method, the clamping mechanism 3 includes symmetrically arranged arc plates 31, two arc plates 31 are slidably arranged on the upper side of the support plate 21, a clamping pad 32 is fixedly installed on the inner side of the arc plate 31, an electric push rod 33 is symmetrically fixedly installed on the upper side of the support plate 21, the output end of the electric push rod 33 is fixedly connected to the arc plate 31, a slide rod 34 is symmetrically fixedly installed on both sides of the arc plate 31, a slide seat 35 is fixedly installed on the upper side of the support plate 21, the slide rod 34 slides through the slide seat 35, a cutting metal part 4 is placed on the upper side of the support plate 21, and the outer side of the cutting metal part 4 abuts against the inner side of the clamping pad 32.

[0029] With the above-mentioned setup, starting the electric push rod 33 can drive the arc plate 31 to clamp the inner cutting metal part 4 on the upper side of the support plate 21. The sliding cooperation between the slide rod 34 and the slide block 35 makes the arc plate 31 more stable when sliding and clamping.

[0030] In this method, a structural folding plate 5 is fixedly installed on the upper side of the lathe 1, and a controller 7 is fixedly installed on the back of the structural folding plate 5. The second stress relief mechanism 6 includes an air pump 61, an air inlet pipe 62 is fixedly connected to the air inlet end of the air pump 61, an air delivery pipe 63 is fixedly connected to the air outlet end of the air pump 61, a transverse pipe 64 is connected to the end of the air delivery pipe 63, and several air jet folding pipes 65 are equidistantly connected to the lower end of the transverse pipe 64. The air delivery pipe 63 passes through to the inside of the structural folding plate 5, and a dust filter screen is sleeved on the end of the air inlet pipe 62.

[0031] With the above setup, the air pump 61 is started, and air is drawn in through the air inlet pipe 62. Subsequently, the air is input into the jet baffle 65 through the air delivery pipe 63 and the transverse passage pipe 64. The jet baffle 65 blows air onto the cutting metal part 4 on the support plate 21 to dissipate heat and slowly cool the metal part to prevent the generation of new internal stress.

[0032] The working principle of the stress relief fixture for lathe cutting metal parts provided by this utility model is as follows:

[0033] During use, after the cutting process is completed, the electric telescopic rod 27 is activated to retract it, causing the limiting block 28 to exit the engagement range with the limiting insertion hole 25, restoring the sliding freedom between the lower end of the structural connecting column 23 and the groove 29. Next, the high-frequency vibration motor 22 is turned on, driving the support plate 21 and the cutting metal part 4 clamped on it to vibrate at high frequency. With the cooperation of the spring 212, the vibration attenuation at the lower end of the structural connecting column 23 is reduced, allowing for more effective transmission of vibration to the metal part. The generated mechanical vibration causes minute displacements of the atoms inside the metal, accelerating the release of internal stress. Furthermore, the vibration frequency and amplitude can be optimized according to the material, size, and shape of the metal part to achieve the best stress relief effect. While the high-frequency vibration motor 22 is running to relieve vibration stress, the air pump 61 is activated. The air pump 61 draws in air through the air inlet pipe 62, and the dust filter at the end of the air inlet pipe 62 filters impurities in the air, ensuring that the air entering the tooling system is clean. The inhaled air is transmitted through the air supply pipe 63 and the transverse passage pipe 64 to the jet nozzle 65, and finally blows air onto the cutting metal part 4 on the support plate 21 to dissipate heat, slowly cooling the metal part and preventing the generation of new internal stress due to temperature changes during stress relief. After vibration stress relief and cooling treatment, the residual stress inside the metal part is effectively eliminated. The high-frequency vibration motor 22 and the air pump 61 are turned off, and the electric push rod 33 is restarted to retract it, driving the arc plate 31 to move outward and releasing the clamp on the cutting metal part 4. At this time, the metal part that has completed the stress relief treatment can be removed from the support plate 21 for subsequent processing or use.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
