Description

Technical Field

[0001] This invention relates to the technical field of small spring thermal positioning mechanism, specifically a small spring thermal high-precision positioning mechanism. Background Technology

[0002] In precision machinery, automotive electronics, medical devices, and micro-actuators, small helical springs are critical elastic components, and their dimensional stability, perpendicularity accuracy, and mechanical performance consistency are paramount. To ensure their long-term reliability, small springs must undergo a crucial heat treatment process called hot setting after cold rolling. Hot setting involves heating the spring to above its normal operating temperature (typically 200–400°C) and holding it at that temperature for a period of time to eliminate residual internal stress generated during winding, stabilize the free height and coil diameter, and significantly improve its resistance to creep, thereby ensuring stable spring force output during long-term use. In current mass production, an online, automated hot setting method is commonly used, where the spring is immediately set while still softened at high temperature after exiting the tempering furnace. This approach typically integrates the hot setting device directly into the tempering furnace outlet to utilize the spring's high-temperature plasticity for rapid shaping. However, in practical applications, existing online hot spring setting equipment is prone to displacement, jumping, or tilting of small springs during high-temperature conveying, leading to clamping position deviations and affecting the setting effect. In addition, most equipment uses rigid pressure heads with fixed spacing to apply pressure to both ends of the spring, which cannot adapt to springs from different batches or those with slight dimensional fluctuations after tempering. This can easily cause excessive hot pressing, resulting in local compression deformation of the spring coil diameter and forming a typical "gourd-shaped" defect, which seriously affects the product qualification rate. Summary of the Invention

[0003] The present invention aims to overcome the shortcomings of the prior art and provide a high-precision positioning mechanism for hot-setting small springs. To solve the above problems, the conveying component can effectively prevent the small springs from being misaligned, falling, or having a heat treatment position deviation due to offset, jumping, or misalignment during the conveying process, ensuring the reliability and repeatability of continuous operation. Furthermore, the hot-setting component can effectively prevent the small springs from being displaced, damaged, or losing verticality control due to dimensional fluctuations, thermal deformation, or rigid clamping during the high-temperature setting process, ensuring stable positioning and flexible clamping during the hot-setting process.

[0031] This application provides a high-precision positioning mechanism for thermally settling small springs. This mechanism, through the arrangement of the conveying components, effectively prevents the small springs from misaligning, falling, or experiencing heat treatment position deviations due to offset, jumping, or misalignment during conveying, ensuring the reliability and repeatability of continuous operation. Furthermore, the thermal setting components effectively prevent the small springs from shifting, being damaged, or losing perpendicularity during high-temperature setting due to dimensional fluctuations, thermal deformation, or rigid clamping, ensuring stable positioning and flexible clamping during the thermal setting process. The following provides a detailed description of this high-precision positioning mechanism for thermally settling small springs. It should be noted that the order of description in the following embodiments is not intended to limit the preferred order of the embodiments.

[0032] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0033] Please see Figure 1-13This embodiment provides a high-precision positioning mechanism for small spring thermal standing, comprising: a base 1, a feeding platform 8 fixedly mounted on the top of the base 1, a bracket 801 fixedly mounted on the top of the base 1, and a tempering furnace 101 fixedly mounted between the base 1 and the feeding platform 8; and a conveying assembly disposed on the top of the base 1 and the feeding platform 8, the conveying assembly comprising: a driven sprocket a104, a chain 105, a limit wheel 106, a sleeve rod 107, a driven sprocket b108, a sprocket 109, a servo motor 2, and a drive sprocket 2. 01; A thermal positioning assembly is installed between the base 1 and the bracket 801. The positioning assembly includes: cylinder 3, heat insulation rod 301, load spring a303, clamping block 304, telescopic cylinder 4, spring block 401, load spring b403 and top block 404; A detection assembly is installed on one side of the tempering furnace 101. The detection assembly includes: rodless cylinder a5, rodless cylinder b6, verticality detection plate 602, equipment box 7, fan 702, hose 703, diverter pipe 704 and air outlet pipe 705.

[0034] The conveying components enable the small spring to be simultaneously loaded, fed smoothly, and positioned on the sleeve 107, effectively preventing the small spring from being misaligned, falling off, or having a heat treatment position deviation due to offset, jumping, or misalignment during the conveying process, thus ensuring the reliability of continuous operation and repeatability of positioning accuracy. Secondly, by setting up the thermal fixing component, it is possible to simultaneously achieve bidirectional clamping, top pressing and elastic adaptive fine adjustment of the small spring after tempering, effectively preventing the small spring from displacement, damage or loss of verticality due to size fluctuation, thermal deformation or rigid clamping during the high temperature fixing process, and ensuring stable positioning and flexible clamping during the thermal fixing process. Next, by setting up the detection components, the verticality detection plate 602 of the thermally fixed small spring can be compared online and the air outlet 705 can be used for uniform air cooling, which can effectively prevent unqualified products from being mixed into the finished product and ensure product quality consistency and process closed-loop control.

[0035] The base 1 has a servo motor 2 fixedly mounted at its bottom. The top of the feeding platform 8 has a drive sprocket 201, which is connected to the drive sprocket 201 via a drive shaft. The top of the feeding platform 8 has multiple sprockets 109. The top of the base 1 has multiple driven sprockets b108 and multiple driven sprockets a104. Each of the driven sprockets a104 and b108 has a limit wheel 106 fixedly mounted on one side. A chain 105 is meshed with the outside of the drive sprocket 201. The chain 105 has multiple sleeve rods 107 evenly distributed at the top; the bottom ends of multiple sprockets 109 are connected to the feed platform 8 through rotating shafts; the bottoms of multiple driven sprockets a104 and multiple driven sprockets b108 are connected to the base 1 through rotating shafts; the outer sides of multiple driven sprockets a104 and multiple driven sprockets b108 are engaged with the chain 105, and the chain 105 passes through the interior of multiple limiting wheels 106; the tempering furnace 101 has an inlet 102 on one side and an outlet 103 on one side.

[0036] In use, the servo motor 2 is started, and the servo motor 2 rotates the drive sprocket 201, which drives the chain 105, multiple sprockets 109, multiple driven sprockets b108 and multiple driven sprockets a104 to rotate. At this time, the user stands on one side of the feeding platform 8 and places the small spring on the outside of the sleeve rod 107. Then, the rotating chain 105 drives the small spring on the outside of the sleeve rod 107 to enter the tempering furnace 101 through the furnace inlet 102. The spring is then heat-treated by the heating element inside the tempering furnace 101 and then conveyed out through the furnace outlet 103.

[0037] Among them, a cylinder 3 is fixedly installed on one side of the base 1, and a heat insulation rod 301 is fixedly connected to one end of the cylinder 3. One end of the heat insulation rod 301 extends into the interior of the tempering furnace 101 and is fixedly connected to a fixing plate 302. A telescopic cylinder 4 is fixedly installed on the top of the bracket 801. The bottom end of the telescopic cylinder 4 passes through the bracket 801 and the tempering furnace 101 and is fixedly connected to a spring block 401. A base plate 306 is fixedly connected to the top of the base 1, and a baffle 309 is fixedly installed on the top of the base 1. Two load springs a303 are fixedly connected to one side of the fixing plate 302. A clamping block 304 is fixedly installed at one end of the load spring a303, and multiple clamping grooves 305 are opened on one side of the clamping block 304; multiple spring grooves 402 are opened inside the spring block 401, and load springs b403 are installed inside the multiple spring grooves 402. The bottom end of the load spring b403 is fixedly connected to a top block 404, and the bottom ends of the multiple top blocks 404 protrude from the bottom of the spring block 401; a guide rail 307 is fixedly installed on the top of the base plate 306, and a slider 308 is fixedly connected to the bottom of the clamping block 304. The slider 308 is slidably connected to the guide rail 307.

[0038] When the chain 105 moves the small spring on the outside of the sleeve 107 between the clamping block 304 and the baffle 309, one side of the small spring contacts the baffle 309. Then, the servo motor 2 is turned off, and the cylinder 3 is started. The cylinder 3 drives the heat insulation rod 301 and the fixing plate 302 to squeeze the two load springs a303, thereby moving the clamping block 304 closer to the small spring on the outside of the sleeve 107 and causing it to enter the clamping groove 305 on one side of the clamping block 304. At this time, the clamping block 304 and the baffle 309 limit the two sides of the small spring, which can provide... The small spring provides stable support and positioning, preventing displacement or shaking during processing and ensuring a stable and reliable standing process. Then, the telescopic cylinder 4 is activated, which controls the spring block 401 to move downward, causing the top block 404 at the bottom of the load spring b403 to contact the top of the small spring held by the clamping block 304. At this time, the small springs with irregular dimensions after partial tempering can also be finely adjusted by the load spring a303 and the load spring b403 to achieve variable flexible clamping, ensuring the stable positioning and flexible clamping of the small spring, thereby realizing the thermal standing of the small spring.

[0039] Among them, a rodless cylinder a5 is installed on one side of the tempering furnace 101. A slider a501 is provided on the rodless cylinder a5. A rodless cylinder b6 is fixedly installed on one side of the slider a501. A rodless cylinder b6 is installed on the rodless cylinder b6. An L-shaped slider 601 is fixedly connected to one side of the rodless cylinder b6. A verticality detection plate 602 is fixedly installed at the bottom of the L-shaped slider 601. An equipment box 7 is fixedly installed on one side of the L-shaped slider 601. A filter screen 701 is fixedly installed on the top of the equipment box 7. A fan 702 is fixedly installed inside the equipment box 7. A hose 703 is connected to the bottom of the equipment box 7. A diversion pipe 704 is fixedly connected to the bottom of the hose 703. Multiple air outlet pipes 705 are fixedly connected to the bottom of the diversion pipe 704.

[0040] After the small springs have completed their thermal settling, the control cylinder 3 and the telescopic cylinder 4 are reset, releasing the small springs that have completed thermal settling from the sleeve rod 107. The servo motor 2 is then activated, rotating the drive sprocket 201 and causing the chain 105, multiple sprockets 109, multiple driven sprockets b108, and multiple driven sprockets a104 to rotate. This removes the thermally settling small springs from the furnace outlet 103 and moves the next row of thermally settling small springs between the clamping block 304 and the baffle 309 for processing. Simultaneously, the rodless cylinder b6 is activated, causing the slider b603 to move the L-shaped slider 601 and the verticality detection plate 602 downwards until one side of the verticality detection plate 602 moves to the side of the sleeve rod 107. Then, the rodless cylinder is activated. Cylinder a5 drives rodless cylinder b6 and verticality detection plate 602 to move left and right, bringing one side of verticality detection plate 602 close to sleeve rod 107. This causes the small spring that has been heated and set to move to one side of sleeve rod 107 and outward along one side of verticality detection plate 602. At this time, by observing the gap between the small spring and one side of verticality detection plate 602, the verticality of the heated and set small spring can be checked, and unqualified small springs can be processed. At the same time, fan 702 is started to generate airflow, which enters the split pipe 704 through hose 703, and then splits into multiple air outlet pipes 705. The airflow is then sprayed from the multiple air outlet pipes 705 onto the heated and set small spring to dissipate heat from the small spring.

[0041] The working principle is as follows: In use, the servo motor 2 is started, and the servo motor 2 rotates the drive sprocket 201, which drives the chain 105, multiple sprockets 109, multiple driven sprockets b108 and multiple driven sprockets a104 to rotate. At this time, the user stands on one side of the feeding platform 8 and places the small spring on the outside of the sleeve rod 107. Then, the rotating chain 105 drives the small spring on the outside of the sleeve rod 107 to enter the tempering furnace 101 through the furnace inlet 102. The spring is then heat-treated by the heating element inside the tempering furnace 101 and then conveyed out through the furnace outlet 103.

[0042] Furthermore, when the chain 105 moves the small spring on the outside of the sleeve rod 107 between the clamping block 304 and the baffle 309, one side of the small spring contacts the baffle 309. Then, the servo motor 2 is turned off, and the cylinder 3 is started. The cylinder 3 drives the heat insulation rod 301 and the fixing plate 302 to squeeze the two load springs a303, thereby driving the clamping block 304 to approach the small spring on the outside of the sleeve rod 107 and make it enter the clamping groove 305 on one side of the clamping block 304. At this time, the clamping block 304 and the baffle 309 limit the two sides of the small spring. This provides stable support and positioning for the small spring, preventing deviation or shaking during processing and ensuring a stable and reliable standing process. Then, the telescopic cylinder 4 is activated, which controls the spring block 401 to move down, causing the top block 404 at the bottom of the load spring b403 to contact the top of the small spring held by the clamping block 304. At this time, the small springs with irregular dimensions after partial tempering can also be finely adjusted by the load spring a303 and the load spring b403 to achieve variable flexible clamping, ensuring the stable positioning and flexible clamping of the small spring, thereby realizing the thermal standing of the small spring.

[0043] Then, after the small springs have completed their thermal settling, the control cylinder 3 and the telescopic cylinder 4 are reset, releasing the small springs that have completed thermal settling from the sleeve rod 107. The servo motor 2 is then activated, rotating the drive sprocket 201 and causing the chain 105, multiple sprockets 109, multiple driven sprockets b108, and multiple driven sprockets a104 to rotate. This removes the thermally settling small springs from the furnace outlet 103 and moves the next row of thermally settling small springs between the clamping block 304 and the baffle 309 for processing. Simultaneously, the rodless cylinder b6 is activated, causing the slider b603 to move the L-shaped slider 601 and the verticality detection plate 602 downwards until one side of the verticality detection plate 602 moves to the side of the sleeve rod 107. Then, the rodless cylinder b6 is activated. The rod cylinder a5 drives the rodless cylinder b6 and the verticality detection plate 602 to move left and right, bringing one side of the verticality detection plate 602 close to the sleeve rod 107. This causes the small spring that has been heated and set to move to one side of the sleeve rod 107 and move outward along one side of the verticality detection plate 602. At this time, by observing the gap between the small spring and one side of the verticality detection plate 602, the verticality of the heated and set small spring can be checked, and unqualified small springs can be processed. At the same time, the fan 702 is started, and the fan 702 generates airflow, which enters the split pipe 704 through the hose 703, and then splits into multiple air outlet pipes 705. The airflow is then sprayed from the multiple air outlet pipes 705 onto the heated and set small spring to dissipate heat from the small spring.
