Technical Field

[0001] This invention relates to the field of wave spring aging processing technology, and more specifically, to a wave spring processing fixture and processing method. Background Technology

[0002] Wave springs are elastic elements with a special waveform cross-section, widely used in precision machinery, aerospace, automotive industries, and other fields to provide stable elastic force and cushioning. Wave springs often require aging treatment during manufacturing to eliminate internal stress, stabilize dimensions, and improve elastic performance.

[0003] Currently, most wave spring clamps on the market adopt a fixed structure, which is suitable for springs of a single specification and has poor versatility. Moreover, the assembly process is cumbersome, making it difficult to achieve quick model change and precise positioning, resulting in low production efficiency, unstable clamping, and affecting the consistency of heat treatment effect and spring performance.

The device includes a lower clamping seat adapted to the bottom end of the wave spring; a support column coaxial with the lower clamping seat is uniformly fixed on the surface of the fixing ring; the support column slides with the sliding sleeve; the upper clamping member includes multiple sets of concentric arc-shaped plates; the arc-shaped plates are adapted to arc-shaped grooves; upper support plates are fixed at both ends of the arc-shaped plates; an upper clamping seat adapted to the top of the wave spring is fixed between two adjacent upper support plates; a number of plug-in parts are uniformly arranged on the surface of the support plate, which are inserted and engaged with the corresponding fixing ring and the outer wall of the arc-shaped plate; and sliding parts adapted to the corresponding plug-in parts are slidably arranged through the surface of the support plate.

[0006] The present invention is further configured such that: each of the two support plates has a plurality of through holes that slide in conjunction with the sliding column and the sliding sleeve; the inner wall of the through holes is symmetrically provided with sliding grooves; and the outer walls of the sliding column and the sliding sleeve are symmetrically fixed with slide rails that slide in conjunction with the corresponding sliding grooves.

[0007] The present invention is further configured such that: a connecting seat is fixed to the bottom of both the sliding column and the sliding sleeve; a support frame is fixed to the inner wall of the through hole; a sliding rod is fixed to the bottom surface of the connecting seat and slides through the support frame; a ball head is fixed to the bottom end of the sliding rod; and a return spring sleeved on the sliding rod is connected between the ball head and the support frame.

[0008] The present invention is further configured such that: the plug-in component includes an ear seat fixed on a support plate; a plug rod is slidably disposed through the side of the ear seat; a guide ball is fixed at one end of the plug rod; a connecting spring sleeved on the plug rod is connected between the guide ball and the ear seat; and the fixing ring and the outer wall of the arc plate are both provided with insertion holes for insertion and engagement with the corresponding plug rods.

[0009] The invention is further configured such that: the sliding member includes a lifting ring; a plurality of L-shaped plates are uniformly fixed on the outer wall of the lifting ring and slide through and cooperate with the support plate; the side of the L-shaped plate is provided with an oblique guide groove adapted to the guide ball; a horizontal plate is fixed on the inner wall of the lifting ring; and a screw rod is rotatably provided on the surface of the horizontal plate and rotates through and cooperates with the support plate.

[0010] The present invention is further configured such that: a first ear plate is symmetrically fixed to the outer wall of the support plate; a second ear plate is fixed to the outer wall of the support plate; a first screw hole is opened on the surface of the first ear plate and the second ear plate on one of the support plates; a guide hole is opened on the surface of the first ear plate on another support plate, and a second screw hole is opened on the surface of the second ear plate thereon.

[0011] The present invention is further configured such that: a fixing member is inserted into each of the two first ear plates on a support plate, and a driving member is inserted into the second ear plate thereon; the fixing member and the driving member both include a U-shaped plate that is inserted into and cooperates with the corresponding first ear plate and the corresponding second ear plate; a fastening bolt is screwed between the U-shaped plate and the first screw hole on the corresponding first ear plate and the corresponding second ear plate; a lifting rod that slides and cooperates with a guide hole on another support plate is fixed on the surface of a U-shaped plate; and a screw that rotates and cooperates with a second screw hole on another support plate is rotatably provided on the surface of the other U-shaped plate.

[0012] A method for machining a wave spring machining fixture includes the following steps: T1. Under the elastic action of the connecting spring, each group of guide balls abuts against the inclined side of the inclined guide groove. By placing the fixing ring of the lower clamp into the arc groove of each group of sliding columns and placing it on the surface of the support plate, the insertion hole is aligned with the corresponding insertion rod. T2. Rotating the screw drives the lifting ring to slide towards the bottom surface of the support plate, thereby driving each set of L-shaped plates to slide. The inclined guide groove guides and squeezes the guide ball, so that the insertion rod is inserted into the insertion hole, completing the locking of the fixed ring. T3. Continue to rotate the screw so that the side of the L-shaped plate slides along the guide ball. During this process, the insertion rod will not move. As the lifting ring continues to move, it squeezes each set of ball heads, thereby driving the sliding column to slide up to fit the lower clamp seat, realizing the assembly of lower clamp parts and lower clamp fixtures of different sizes. T4. Same as above, complete the assembly of the upper clamping part and the upper clamping fixture; T5. Place the corresponding wave spring on the corresponding support column, rotate the screw, thereby driving the upper clamping part and the upper clamping fixture to move synchronously towards the lower clamping part and the lower clamping fixture, so that the wave spring is stably clamped between the lower clamping seat and the upper clamping seat. Place the entire processing device in a vacuum aging furnace for aging treatment. After aging treatment, take out each wave spring and perform an elasticity test. Use a testing machine to perform compression test and height test on the aging treated wave spring to see if they meet the specified requirements.

[0013] The advantages of this invention are: This invention utilizes a sliding adjustable sliding column and sliding sleeve structure, along with replaceable upper and lower clamps, to achieve rapid adaptation to wave springs of different diameters, waveforms, and heights, thereby improving the applicability and production flexibility of the fixture.

[0014] This invention employs a plug-in positioning and lead screw drive linkage mechanism to achieve "one-click" locking and releasing, significantly reducing manual adjustment time and improving assembly efficiency. It is particularly suitable for mass production scenarios. The upper and lower clamps are precisely matched with the waveform of the wave spring. Combined with the elastic reset and plug-in locking mechanism, it ensures that the wave spring is subjected to uniform force during clamping, avoids local deformation or stress concentration, and guarantees dimensional stability and performance consistency during heat treatment.

Then, the upper clamping part 7 and the lower clamping part 8 are quickly clamped and released from the upper clamping fixture 1 and the lower clamping fixture 2, respectively, by means of the coordinated action of the plug-in part and the sliding part. This structure can be adapted to wave springs of different sizes and ensures that the spring force is uniform during the clamping process, which is suitable for subsequent heat treatment processes.

[0035] Example 2, please refer to Figure 1-14This embodiment 2 is an improvement on the first embodiment as follows: Specifically, the surfaces of the two support plates 3 are provided with several through holes 16 that slide with the sliding column 4 and the sliding sleeve 5; the inner walls of the through holes 16 are symmetrically provided with sliding grooves 17; the outer walls of the sliding column 4 and the sliding sleeve 5 are symmetrically fixed with slide rails 18 that slide with the corresponding sliding grooves 17.

[0036] The bottom of the sliding column 4 and the sliding sleeve 5 are both fixed with connecting seats 19; the inner wall of the through hole 16 is fixed with a support frame 20; the bottom surface of the connecting seat 19 is fixed with a sliding rod 21 that slides through the support frame 20; the bottom end of the sliding rod 21 is fixed with a ball head 22; a return spring 23 sleeved on the sliding rod 21 is connected between the ball head 22 and the support frame 20.

[0038] The sliding component includes a lifting ring 29; several L-shaped plates 30 are uniformly fixed on the outer wall of the lifting ring 29 and slide through the support plate 3; the side of the L-shaped plate 30 is provided with an oblique guide groove 31 that matches the guide ball 26; a horizontal plate 32 is fixed on the inner wall of the lifting ring 29; a screw 33 is rotatably provided on the surface of the horizontal plate 32 and rotates through the support plate 3.

[0039] The outer wall of the support plate 3 is symmetrically fixed with a first ear plate 34; the outer wall of the support plate 3 is fixed with a second ear plate 35; the first ear plate 34 and the second ear plate 35 on one support plate 3 are both provided with a first screw hole 36; the first ear plate 34 on the other support plate 3 is provided with a guide hole 37, and the second ear plate 35 on it is provided with a second screw hole 38.

[0040] Two first ear plates 34 on a support plate 3 are each fitted with a fixing member 39, and a second ear plate 35 on the support plate is fitted with a driving member 40. Both the fixing member 39 and the driving member 40 include a U-shaped plate 41 that is fitted with the corresponding first ear plate 34 and second ear plate 35. Fastening bolts 42 are screwed between the U-shaped plate 41 and the first screw hole 36 on the corresponding first ear plate 34 and second ear plate 35.

A screw 44 is rotatably fitted on the surface of the other U-shaped plate 41 and threadedly rotates with the second screw hole 38 on another support plate 3.

[0041] Working principle of this embodiment two: Rotating the lead screw 33 drives the lifting ring 29 to move downwards. The inclined guide groove 31 on the L-shaped plate 30 pushes the guide ball 26 and the insertion rod 25 inwards, inserting them into the fixing ring 9 or the insertion hole 28 of the arc plate 13 to achieve locking. Continuing to rotate the lead screw 33, the lifting ring 29 continues to move downwards and presses against the ball head 22, pushing the sliding column 4 upwards, so that the sliding column 4 is pressed against the lower clamping seat 11, completing the assembly of the lower clamping part 8.

By placing the fixing ring 9 of the lower clamp 8 into the arc groove 6 of each group of sliding columns 4 and placing it on the surface of the support plate 3, the insertion hole 28 is aligned with the corresponding insertion rod 25. T2. Rotating screw 33 drives lifting ring 29 to slide towards the bottom surface near support plate 3, thereby driving each group of L-shaped plates 30 to slide. Inclined guide groove 31 guides and squeezes guide ball 26, so that insertion rod 25 is inserted into insertion hole 28 to complete locking of fixed ring 9. T3. Continue to rotate the screw 33 so that the side of the L-shaped plate 30 slides along the guide ball 26. During this process, the insertion rod 25 will not move. As the lifting ring 29 continues to move, it squeezes each group of ball heads 22, thereby driving the sliding column 4 to slide up to fit against the lower clamp seat 11, so as to realize the assembly of lower clamp parts 8 of different sizes and lower clamp fixture 2. T4. Same as above, complete the assembly of upper clamping part 7 and upper clamping fixture 1; T5. Place the corresponding wave spring on the corresponding support column 12, rotate the screw 44, thereby driving the upper clamping piece 7 and the upper clamping fixture 1 to move synchronously towards the lower clamping piece 8 and the lower clamping fixture 2, so that the wave spring is stably clamped between the lower clamping seat 11 and the upper clamping seat 15. Place the entire processing device in a vacuum aging furnace for aging treatment. After aging treatment, take out each wave spring and perform an elasticity test.
