Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and more specifically, it relates to a shot peening device for suspension springs. Background Technology

[0002] Shot peening of automotive suspension springs is a key surface strengthening process. It involves high-speed spraying of numerous fine shot pellets that impact the spring surface, causing plastic deformation and introducing residual compressive stress into the surface layer. This process significantly inhibits the initiation and propagation of fatigue cracks, effectively improving the spring's fatigue strength and resistance to stress corrosion. Shot-peened suspension springs exhibit longer service life and higher reliability when subjected to continuous vibrations and impact loads during vehicle operation, making it a standard process for ensuring the safety and durability of automotive suspension systems.

[0003] Currently, in existing technologies, the suspension springs in shot blasting devices are in a fixed position during shot blasting, and the position of the shot blasting device does not change. To achieve uniform shot blasting of the suspension springs, it is necessary to adjust their position. The current method uses a motor to drive a lead screw to rotate, with positive and negative threads set on both sides of the lead screw. The mounting ends of two transmission rollers are fixed on the positive and negative thread sides, respectively, thereby enabling the transmission rollers to move closer and further away. The dynamic adjustment of the suspension springs during the shot blasting process is achieved by moving the transmission rollers closer and further away.

[0004] However, while directly using a motor and lead screw to move two transmission rollers can solve the displacement problem of the suspension spring, it is difficult to accurately control the movement distance and positioning accuracy of the suspension spring. It is also difficult to observe the real-time position change of the suspension spring during its movement through the transmission rollers, which can easily cause the shot peening area to deviate from the preset trajectory, affecting the uniformity and consistency of the strengthening effect.

[0005] Therefore, this utility model proposes a shot peening device for suspension springs. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a shot peening device for suspension springs.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A shot peening device for suspension springs, characterized in that it includes a fixed base, an adjusting assembly, a displacement assembly, and two fastening assemblies.

Therefore, the phrases "in one embodiment," "in some embodiments," or "in some of these embodiments" appear in various places throughout the specification, and not all refer to the same embodiment. Furthermore, in one or more embodiments, a particular feature, structure, or characteristic may be combined in any suitable manner.

[0028] Example 1, please refer to Figures 1-6 The present invention provides the following technical solution: See Figure 1 , Figure 2 , Figure 3 and Figure 4 The shot peening equipment includes an adjustment component 8, a fixed base 1, a displacement component 2, and two fastening components 5. The two fastening components 5 are respectively installed at both ends of the displacement component 2. A limit component 3 is fixedly installed on the fixed base 1. The lower part of one fastening component 5 is fixed to the limit component 3, and the lower part of the other fastening component 5 is fixed to a sliding component 4. An indicator component 7 is installed on the limit component 3, and a scale plate 6 is sleeved on the sliding component 4.

[0029] The adjustment assembly 8 includes an adjustment motor 81. A lead screw 84 is mounted on one end of the adjustment motor 81. The two ends of the lead screw 84 are respectively provided with a positive thread and a negative thread. A first adjustment seat 85 is installed at the end with the positive thread, and a second adjustment seat 86 is installed at the end with the negative thread. By rotating the lead screw 84, the first adjustment seat 85 and the second adjustment seat 86 can be moved in opposite directions or in opposite directions to achieve precise spacing adjustment. A first adjustment roller 82 is installed on the first adjustment seat 85, and a second adjustment roller 83 is installed on the second adjustment seat 86. When the adjustment motor 81 rotates in the forward direction, it drives the lead screw 84 to rotate. The rotation of the lead screw 84 in the forward direction drives the first adjustment seat 85 and the second adjustment seat 86 to move closer to each other, and simultaneously drives the first adjustment roller 82 and the second adjustment roller 83 to move closer to each other, thereby raising the position of the suspension spring.

[0030] The fixed base 1 supports the position of the fixed limiting component 3. The displacement component 2 connects the two fastening components 5 and maintains their relative position stability. The fastening component 5 fixed to the limiting component 3 stabilizes the installation position of the displacement component 2, preventing the displacement component 2 from shifting or loosening, and ensuring the rigidity and positioning accuracy of the overall structure. The fastening component 5 fixed to the sliding component 4 is used for movement, displaying the movement distance of the displacement component 2. The scale plate 6 and the indicator component 7 cooperate to display the real-time displacement distance between the first adjusting roller 82 and the second adjusting roller 83. The fixed base 1 includes a support platform 11, on which a sliding groove 12 is provided, and part of the sliding component 4 is placed in the sliding groove 12.

[0031] The support platform 11 provides a position for the sliding groove 12. The sliding groove 12 is used to limit the movement range of the sliding component 4, prevent it from exceeding the preset stroke, ensure the accuracy of displacement measurement, and avoid structural damage caused by excessive displacement.

[0032] See Figure 1When the first adjusting roller 82 moves, it drives the first adjusting seat 85 to move. The first adjusting seat 85 is fixed to the sliding assembly 4. The first adjusting seat 85 drives the sliding assembly 4 to move outward. At this time, the scale plate 6 moves, and the position of the indicating assembly 7 on the scale plate 6 shifts. The scale on the scale plate 6 corresponds to the distance between the first adjusting roller 82 and the second adjusting roller 83. At the initial position of the indicating assembly 7, the baseline of the scale plate 6 represents the initial distance between the first adjusting roller 82 and the second adjusting roller 83, which is taken as the zero value. On the specific scale, the distance that the first adjusting roller 82 moves is doubled on the scale plate 6, which represents the real-time value of the change in the distance between the first adjusting roller 82 and the second adjusting roller 83, and at the same time drives the displacement assembly 2. One end moves, adjusting the position of the indicator component 7 on the scale plate 6. The adjusting motor 81 rotates in the opposite direction, driving the lead screw 84 to rotate in the opposite direction, causing the first adjusting seat 85 and the second adjusting seat 86 to move away from each other. Simultaneously, the first adjusting roller 82 and the second adjusting roller 83 are separated. The first adjusting roller 82 drives the sliding component 4 to move inward, the scale plate 6 moves, and the position of the indicator component 7 on the scale plate 6 shifts, thereby reflecting the real-time change in the increase of the distance between the first adjusting roller 82 and the second adjusting roller 83, thus reducing the suspension spring height. At the same time, one end of the traction displacement component 2 is displaced, adjusting the corresponding position of the indicator component 7 on the scale plate 6, thereby realizing the specific display of the adjustment distance when adjusting the distance between the first adjusting roller 82 and the second adjusting roller 83.

[0033] The displacement assembly 2 includes a fixed rod 22, a driven member 21 is sleeved on the fixed rod 22, a driven connector 24 is sleeved on one end of the driven member 21, a drive groove 23 is provided on the driven member 21, and two fastening assemblies 5 are respectively fixed on the driven connector 24 and the fixed rod 22.

[0034] The fixed rod 22 restricts the position of the driven member 21, which can slide on the fixed rod 22. The fixed rod 22 guides the sliding of the driven member 21. The drive groove 23 is used to connect wires and transmit electrical signals and voltage. When the positions of the fixed rod 22 and the driven member 21 change, the internal voltage changes synchronously. The change value is correlated with the movement distance of the first adjusting roller 82 and the second adjusting roller 83 on the lead screw 84. The host computer obtains the specific movement value based on the voltage, so that the measuring device can monitor the distance change between the two first adjusting rollers 82 and the second adjusting roller 83 in real time. Power is applied to adjust the sliding distance of the driven member 21 on the fixed rod 22. The driven connector 24 is fixed to another fastening component 5, supporting the driven member 21 and moving synchronously with the driven member 21.

[0035] See Figure 5The limiting component 3 includes a limiting plate 31, on which a limiting fixing plate 32 and a first support platform 33 are respectively installed. The limiting fixing plate 32 is fixed on the support platform 11, and the limiting plate 31 is also provided with a limiting detection groove 36.

[0036] The limiting plate 31 provides an installation base for the limiting fixing plate 32 and the first support platform 33. The limiting fixing plate 32 enhances the overall structural stability of the limiting assembly 3 through its fixed connection with the support platform 11. The first support platform 33 is used to position and fix one of the fastening components 5 to ensure that the fastening component 5 does not shift during operation and to avoid inaccurate measurement. The limiting detection groove 36 is used to provide the installation position.

[0037] Two limit sensors 34 are evenly spaced in the limit detection groove 36, and limit rings 35 are fitted at both ends of the two limit sensors 34.

[0038] The limit sensor 34 is used to detect the displacement distance of the sliding component 4. By sensing the position change of the sliding component 4 in the sliding groove 12, the displacement signal is converted into an electrical signal and output to the host computer, so as to realize the accurate monitoring of the displacement during the shot peening process of the suspension spring. The limit ring 35 is sleeved on both ends of the limit sensor 34, and limits the limit sensor 34 from both ends to prevent it from loosening or shifting in the vibration environment, and to ensure the stability of signal acquisition.

[0039] The sliding assembly 4 includes a sliding positioning plate 41, on which a sliding connecting plate 42 and a second support platform 43 are respectively installed. Part of the second support platform 43 is disposed in the sliding groove 12.

[0040] The sliding positioning plate 41 provides an installation reference for the sliding connecting plate 42 and the second support platform 43. Another fastening component 5 is installed on the sliding connecting plate 42 to ensure its stability during movement. The second support platform 43 slides along a preset trajectory in the sliding groove 12 to avoid skew or jamming, ensuring linear displacement and accurate measurement results.

[0041] See Figure 5 The fastening assembly 5 includes a fixing block 51, a mounting groove 52 is provided on the fixing block 51, a plug rod 53 is installed in the mounting groove 52, and elastic fasteners 54 are symmetrically arranged on the outside of the mounting groove 52 on the plug rod 53.

[0042] The fixing block 51 provides a connection for the displacement component 2, and the mounting groove 52 provides a insertion position for the plug rod 53. When the mounting groove 52 is inserted into the plug rod 53, the elastic fastener 54 fixes the position of the plug rod 53 from both sides. The plug rods 53 of the two fastening components 5 are respectively inserted into the through holes of the driven connector 24 and the fixing rod 22 to fix the positions of both ends.

[0043] The indicator component 7 includes a mounting slot 71, an indicator connection plate 72 is fixed on the mounting slot 71, and an indicator pin 73 is mounted on the indicator connection plate 72.

[0044] The mounting slot 71 is fixed on the limiting plate 31, and a fastening component 5 is fixed on the first support platform 33.

[0045] The mounting slot 71 provides a mounting base for the indicator connection plate 72. The indicator connection plate 72 ensures stability during the indication process through a fixed connection with the mounting slot 71. The indicator needle 73 is used to display measurement data in real time. The indicator needle 73 cooperates with the scale plate 6 to convert the measurement signal into a visual reading, which makes it easy for operators to monitor the deformation of the suspension spring during the shot peening process in real time.

[0046] By setting two fastening components 5 respectively installed at both ends of the displacement component 2, the limiting component 3 is fixed on the fixed base 1, the indicating component 7 is installed on the limiting component 3, and the scale plate 6 is sleeved on the sliding component 4, when the first adjusting roller 82 and the second adjusting roller 83 move, voltage is applied to the drive groove 23, the driven member 21 slides along the fixed rod 22, the voltage change is transmitted to the host computer, and the distance between the first adjusting roller 82 and the second adjusting roller 83 is displayed. The first adjusting roller 82 drives the sliding component 4 to move, and the sliding component 4 drives the driven connector 24 to move synchronously, so that the fastening components 5 at both ends move with the displacement component 2 and maintain the corresponding position. At the same time, the indicating component 7 cooperates with the scale plate 6 to read the displacement change in real time, and feeds back the displacement change at this time to the host system, thus achieving the effect of real-time monitoring and display of the displacement of the suspension spring during shot blasting.

[0047] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
