Description
Technical Field
[0001] This invention relates to the field of strip spring technology, and more specifically, to a strip spring production line equipment. Background Technology
[0002] There are approximately 440 nuclear power units in operation worldwide, the vast majority (about 92%) of which are light water reactors (LWRs), with the remainder being heavy water reactors (PHWRs) and advanced gas-cooled reactors (AGRs). Light water reactors are mainly of two types: pressurized water reactors (PWRs) and boiling water reactors (BWRs), with approximately 75% being pressurized water reactors.
[0003] The core of a pressurized water reactor nuclear power plant consists of many fuel assemblies. The end grids of the fuel assemblies and the mixing grids are collectively referred to as improved grids. Except for the mixing blades contained in the inner strips of the mixing grid, the structure and dimensions of these two types of grids are identical. Each improved grid contains 32 inner strips, 244 double springs, and 40 single springs. There are 16 types of inner strips, 14 of which require assembly and welding with single and double springs. The four slots on the strips are single spring assembly slots, and the slots at the top and bottom of the strips are double spring assembly slots.
[0004] The existing improved grid strip spring processing process includes spring feeding, shearing, spring and strip assembly, strip spring verification and shearing. All of the above processes are carried out independently and manually, resulting in low processing efficiency and making it unsuitable for large-scale production.

[0140] Please refer to Figures 2-5 This embodiment provides a strip spring production line equipment. The strip positioning component includes a positioning strip 102, which is vertically arranged on the mounting base 101.
[0141] The aforementioned strip clamping assembly includes clamping blocks 103, elastic guide rods 104, guide shafts 105, and eccentric handles 106. Multiple elastic guide rods 104 and clamping blocks 103 are provided, with the clamping blocks 103 evenly spaced and closely abutting one side of the positioning strip 102. One end of each elastic guide rod 104 passes through the lower part of the positioning strip 102 and connects to the clamping blocks 103, while the other end is fixedly connected to the side wall of the guide shaft 105. One end of the guide shaft 105 is connected to the eccentric handle 106, and the other end is connected to the eccentric rotating member 107. The bottom of the eccentric handle 106 is connected to the mounting base 101 via a first elastic member 108. The rotation centers of the eccentric handle 106 and the eccentric rotating member 107 are located on the same horizontal line and are parallel to the guide shaft 105. The guide shaft 105 is located on the line of the smaller rotation radius of the eccentric handle 106 and the eccentric rotating member 107.
[0142] This embodiment of the application uses a mounting base 101, a strip positioning assembly, and a strip clamping assembly, with the strip positioning assembly and strip clamping assembly positioned above the mounting base 101. The strip positioning assembly includes a positioning strip 102, which is vertically positioned on the mounting base 101. The strip clamping assembly includes clamping blocks 103, elastic guide rods 104, guide shafts 105, and eccentric handles 106. Multiple elastic guide rods 104 and clamping blocks 103 are provided, with the multiple clamping blocks 103 evenly spaced and tightly attached to one side of the positioning strip 102. One end of the multiple elastic guide rods 104... The lower part of the positioning bar 102 is connected to multiple clamping blocks 103, and the other end is fixedly connected to the side wall of the guide shaft 105. One end of the guide shaft 105 is connected to the eccentric handle 106, and the other end is connected to the eccentric rotating member 107. The bottom of the eccentric handle 106 is connected to the mounting base 101 through the first elastic member 108. The rotation centers of the eccentric handle 106 and the eccentric rotating member 107 are located on the same horizontal line and are parallel to the guide shaft 105. The guide shaft 105 is located on the line of the smaller rotation radius of the eccentric handle 106 and the eccentric rotating member 107. The strip 1018 is positioned by the positioning bar 102, and the strip 1018 is clamped onto the positioning bar 102 by the clamping block 103. When it is necessary to remove the strip 1018, the eccentric handle 106 is pressed down. Under the eccentric action of the eccentric handle 106 and the eccentric rotating part 107, the guide shaft 105 moves diagonally upward toward the side of the strip 1018, thereby driving the elastic guide rod 104 and the clamping block 103 to move horizontally upward in the same direction, thereby releasing the positioning bar 102 and the clamping block 103, and the strip 1018 can be removed. After the eccentric handle 106 is released, under the elastic restoring force of the first elastic element 108, the eccentric handle 106... 6 drives the guide shaft 105, elastic guide rod 104, and clamping block 103 to reset, thereby allowing another strip 1018 to be installed on the positioning bar 102. By setting multiple elastic guide rods 104 and clamping blocks 103 to uniformly and reliably clamp the strip 1018, the inner strip 1018 is ensured to be stable in the tooling fixture without slippage or tilting. The strip tooling structure of the present invention is simple and reliable, and easy to operate. The strip 1018 can be quickly picked up and put down by pressing the eccentric handle 106. The positioning bar 102 and clamping block 103 and other structures can accurately position the strip 1018 on the strip tooling, and the strip 1018 can be stably and firmly clamped on the tooling.
[0143] The strip tooling in this exemplary embodiment will now be further described.
[0144] In some embodiments of the present invention, the above-mentioned strip positioning assembly includes a positioning strip 102, which is vertically disposed on the mounting base 101. The positioning strip 102 is composed of a positioning plate 1020 at the bottom and a plurality of spaced positioning teeth 1021 at the top of the positioning plate 1020. That is, the positioning strip 102 is comb-shaped, which ensures an effective positioning contact surface while reasonably avoiding the positions of springs and welding points, ensuring no deformation after welding and meeting the dimensional technical requirements after welding. The strip 1018 is fixed on the positioning strip 102, and the position of the strip 102 is initially positioned by the positioning strip 102. Furthermore, the aforementioned strip positioning assembly also includes a scale positioning head 1012. The scale positioning head 1012 is modified from a suitable micrometer measuring head, i.e., it has the same scale adjustment range as the micrometer. The scale positioning head 1012 is mounted on the bracket 1013, and the end of the scale positioning head 1012 abuts against the end of the strip 1018. After the strip 1018 is mounted on the positioning bar 102, the feed and retraction length of the scale positioning head 1012 are adjusted to fine-tune the strip 1018 and adjust the relative position of the end of the strip 1018 with the tooling.
[0145] In some embodiments of the present invention, the strip clamping assembly includes clamping blocks 103, elastic guide rods 104, guide shafts 105, and eccentric handles 106. Multiple elastic guide rods 104 and clamping blocks 103 are provided, with the multiple clamping blocks 103 evenly spaced and closely abutting one side of the positioning strip 102. One end of each elastic guide rod 104 passes through the lower part of the positioning strip 102 and is connected to one of the multiple clamping blocks 103, while the other end is fixedly connected to the side wall of the guide shaft 105. Preferably, each elastic guide rod 104 and clamping block 103 is provided, using multiple clamping blocks 103 to uniformly and reliably clamp the strip 1018, ensuring that the inner strip 1018 does not shift or tilt in the tooling fixture, thus meeting product manufacturing technical requirements, and without changing the size of the inner strip 1018 or causing external scratches. One end of the guide shaft 105 is connected to the eccentric handle 106. 6. One end is connected to the other end, and the other end is connected to the eccentric rotating component 107. The bottom of the eccentric handle 106 is connected to the mounting base 101 via the first elastic element 108, wherein the first elastic element 108 is a first spring. The rotation centers of the eccentric handle 106 and the eccentric rotating component 107 are located on the same horizontal line and are parallel to the guide shaft 105. The guide shaft 105 is located on the line of the smaller rotation radius of the eccentric handle 106 and the eccentric rotating component 107. The opposite outer end faces of the eccentric handle 106 and the eccentric rotating component 107 are respectively connected to the fixed seat 1010 via the rotating shaft 109. The two rotating shafts 109 are respectively located at the rotation centers of the eccentric handle 106 and the eccentric rotating component 107. The fixed seat 1010 is fixed on the mounting base 101. The rotating shafts 109 enable the eccentric handle 106 and the eccentric rotating component 107 to rotate synchronously.
[0146] It should be noted that the guide shaft 105 is positioned on the smaller rotation radius line of the eccentric handle 106 and the eccentric rotating component 107. When the eccentric handle 106 is pressed down, the guide shaft 105 moves obliquely upward toward the strip 1018 as the radius of the eccentric handle 106 and the eccentric rotating component 107 changes. This causes multiple elastic guide rods 104 to move obliquely upward, thereby causing the clamping block 103 to move obliquely upward and separate from the positioning strip 102. The strip 1018 can then be removed. After the eccentric handle 106 is released, the clamping block 103 can be reset under the action of the first spring.
[0147] As an example, the aforementioned elastic guide rod 104 includes a top rod 1040, a fixing member 1041, a second elastic member 1042, and a sleeve 1043. The fixing member 1041 is located at one end of the top rod 1040 near the guide shaft 105 and is fixedly connected to the guide shaft 105. The sleeve 1043 is sleeved on the outside of the top rod 1040. The second elastic member 1042 is located between the sleeve 1043 and the fixing member 1041, wherein the second elastic member 1042 is a second spring. By providing a second spring on the top rod 1040, the pressure on the elastic guide rod 104 can be reduced, thereby reducing the frictional force when the clamping block 103 and the positioning strip 102 are clamped or released, further protecting the strip 1018 from scratches and damage.
[0148] As an example, the mounting base 101 is provided with a mounting box 1011, which is located between the positioning strip 102 and the guide shaft 105. Through holes are provided on both sides of the mounting box 1011. The portion of the push rod 1040 fitted with a sleeve 1043 is located inside the mounting box 1011, and the sleeve 1043 is connected to the mounting box 1011. Both ends of the push rod 1040 protrude through the through holes on both sides. The mounting box 1011 covers the multiple push rods 1040, providing protection for them.
[0149] In some embodiments of the present invention, the bottom surface of the mounting base 101 is provided with a clamp stop groove 1014, which extends from one end of the mounting base 101 near the scale positioning head 1012 along the direction of the strip 1018 to the end near the end of the strip 1018.
[0150] In one specific implementation, the aforementioned mounting base 101 moves on the tooling transfer device and is restricted when it moves to the end of the clamp stop groove 1014, thereby fixing the welding stroke of the strip tooling.
[0151] In some embodiments of the present invention, a data read / write chip 1015 is mounted on the bottom surface of the mounting base 101. Specifically, the data read / write chip 1015 is an RFID data carrier chip used to store various information about the products on the strip tooling. A non-contact RFID read / write head is located at the relevant workstation. When the strip tooling reaches the relevant workstation, the product's pending processing information and completed processing information can be stored in the chip. In this embodiment, the RFID data carrier uses Balluff's industrial RFID system. Using the RFID system, targets can be automatically identified and traced. Data is transmitted between the data carrier and the read / write head, and forwarded to the control system through the analysis unit.
[0152] In some embodiments of the present invention, the bottom surface of the mounting base 101 is provided with a plurality of positioning pin holes 1016. The positioning pin holes 1016 are used for positioning devices at positions such as the spring / strip 1018 assembly station, the upper and lower welding point welding station, and the spring curvature height measurement station to quickly and reliably position the strip tooling itself.
[0153] In some embodiments of the present invention, the bottom surface of the mounting base 101 is further provided with a plurality of telescopic pins 1017. The telescopic pins 1017 are used for safe guidance in the transmission device to ensure smooth and deviation-free movement.
[0154] In some embodiments of the present invention, the mounting base 101 is provided with a radio frequency identification system, which is electrically connected to the control unit. The radio frequency identification system includes an RFID chip, a read / write head, a data processor, and several RDIF read / write heads.
[0155] In the above embodiments, each strip tooling is equipped with an RFID chip. When it reaches each workstation, the product data on the tooling is obtained through the reading head, then processed by the data processor, and finally processed by the control system.
[0156] RFID data carrier chips are used to store various information about products on the strip tooling. There are non-contact RFID readers at the relevant workstations. When the strip tooling reaches the relevant workstation, the product's information on what to be processed and what has been processed can be stored in the chip.
[0157] RDIF read / write heads are installed on the positioning devices at the operating stations and at stations such as spring / strip assembly, bottom welding, and spring curvature height measurement, so that the control system can identify the product and read / write information. Example 3
[0158] Please refer to Figures 6-10This embodiment provides a strip spring production line equipment. The tooling transmission unit includes a ring track composed of multiple support frame units 201. Each of the multiple support frame units 201 is provided with multiple conveyor lines 202. Adjacent support frame units 201 are provided with multiple turning components 203.

[0159] The transmission device includes multiple support frame units 201, which together form a rectangular support frame. Each support frame unit 201 is equipped with a conveyor line 202 for conveying the tooling. Turning components 203 are provided between adjacent support frame units 201. Since the support frame is composed of multiple support frame units 201 forming a rectangle, the turning components 203 allow the tooling to rotate between the support frame units 201. This allows the tooling, when moving to one end of a single support frame unit 201, to rotate to the other side of the support frame unit 201 under the influence of the turning components 203 and continue transmission. The turning components 203 are located on the inner side of the support frame units 201, specifically at the four corners facing inwards towards the support frame. The turning assembly 203 is specifically composed of connecting blocks, which are mounted on adjacent support frame units 201. The connecting blocks have arc-shaped grooves that allow the tooling to be adjusted in position, turning it from one support frame unit 201 to another. Each support frame unit 201 also has multiple positioning devices 204, which stop the tooling traveling on the conveyor line 202 on the support frame unit 201, facilitating related operations after it stops. A drive device 205 is also mounted on the support frame unit 201, which drives the conveyor line 202 and provides power to the positioning devices 204, etc. This invention can shorten the transmission line of the tooling transport device, reducing the cost of the tooling transport device.
[0160] In actual use, there are four conveyor lines, each consisting of two long-side conveyor lines and two short-side conveyor lines. There are at least four turning assemblies 203, located at the four right angles inside the support frame. The connecting blocks in the turning assembly 203 are L-shaped, with two sides of the connecting block respectively set on two adjacent support frame units 201. The arc-shaped groove is set on the surface of the connecting block that contacts the tooling.
[0161] In some embodiments of the present invention, a plurality of the above-mentioned support frame units 201 are provided with through grooves 206, and a plurality of the above-mentioned positioning devices 204 are located inside the through grooves 206.

[0163] In some embodiments of the present invention, the plurality of the above-mentioned conveyor lines 202 include conveyor belts disposed on the plurality of the above-mentioned support frame units 201, the conveyor belts being located on both sides of the above-mentioned through groove 206, the plurality of the above-mentioned support frame units 201 being provided with rotating rods that are driven and connected to the above-mentioned driving device 205, and the rotating rods being provided with pulleys that cooperate with the above-mentioned conveyor belts.
[0164] In actual use, the conveyor line 202 is specifically a conveyor belt. The conveyor belt is set at both ends of the through groove 206 on the support frame unit 201. A rotating rod is rotatably connected to the end of the support frame unit 201. A pulley that cooperates with the conveyor belt is set on the rotating rod to drive the rotation of the conveyor belt.

[0204] Please refer to Figures 17-23 This embodiment provides a production line equipment for strip spring 40505. The spring 40505 clamping unit includes a frame 401, a horizontal moving component 402 is provided on the frame 401, and a clamping component 404 is provided at the front end of the horizontal moving component 402.
[0205] The aforementioned horizontal moving component 402 includes a connecting arm 40201, the fixed end of which is connected to the frame 401, and the moving end of which is connected to the clamping component 404. A first pneumatic drive component 406 is provided on the frame 401, and the other end of the first pneumatic drive component 406 is connected to the clamping component 404. The clamping component 404 is provided with a vertical moving component 403.
[0206] The vertical moving component 403 includes a connecting block 40301. The front and rear ends of the connecting block 40301 are respectively connected to the horizontal moving component 402 and the clamping component 404. The upper end of the connecting block 40301 is connected to a second pneumatic drive component 405.
[0207] The aforementioned gripping assembly 404 includes a connecting plate 40401, which is connected to the connecting block 40301. The connecting plate 40401 is provided with a pressing member 408, a third pneumatic drive member 409 is provided at the upper end of the pressing member 408, and a pneumatic finger 40302 is provided at the lower end of the pressing member 408.
[0208] The connecting arm 40201 may include multiple connecting components, which are connected end to end by hinges. The connecting arm 40201 is U-shaped. When the first pneumatic drive 406 is driven, the moving end of the connecting arm 40201 can be pulled to move linearly. During the movement, the connecting components at the curved part of the connecting arm 40201 rotate relative to each other, so that the curved part of the connecting arm 40201 will produce a corresponding deformation during the force-driven movement, thereby ensuring the support and protection function of the connecting arm 40201 and improving the stability of the entire device movement.
[0209] Specifically, the aforementioned pressing component 408 includes a mounting block 40801, which is connected to the lower end of the connecting plate 40401. The lower end of the third pneumatic drive component 409 passes through the mounting block 40801 and connects to the pneumatic finger 40302. A fourth pneumatic drive component is provided at the upper end of the mounting block 40801. Power is supplied to the fourth pneumatic drive component through an external air supply device and air pressure pipeline. The fourth pneumatic drive component then controls the pneumatic finger 40302 to achieve a precise opening and closing state. Due to the high sensitivity and high precision of pneumatic drives, precise control in time and space is possible when clamping and placing parts.
[0210] The aforementioned third pneumatic drive component 409 includes a third pneumatic cylinder, which is connected to the aforementioned mounting block 40801. The third pneumatic cylinder is provided with a third pneumatic rod, which is connected to a pressure block 40802. The other end of the pressure block 40802 is connected to the aforementioned pneumatic finger 40302.
[0211] The third pneumatic drive component 409 can drive the pneumatic finger 40302 to perform a downward pressing motion after the vertical moving component 403 moves to a reasonable position, so that the pneumatic finger 40302 can move accurately and quickly to the spring 40505 placement box or clamping station to complete the clamping or placement of the spring 40505. The aforementioned horizontal moving component 402 also includes a mounting plate 40202. The front end of the mounting plate 40202 is slidably connected to the connecting block 40301, and the mounting plate 40202 is connected to the moving end of the connecting arm 40201. The first pneumatic drive component 406 is connected to the mounting plate 40202. The mounting plate 40202 can connect the connecting arm 40201, the first pneumatic drive component 406, and the connecting block 40301. This ensures that when the first pneumatic drive component 406 is driven in the horizontal direction, the mounting plate 40202 can pull the moving end of the connecting arm 40201 and the gripping component 404 to move synchronously, thus improving the reliability of the gripping process.
[0212] It is worth noting that the first pneumatic drive 406 drives the entire horizontal moving assembly 402 to move linearly back and forth relative to the clamping assembly direction, but cannot move in the lateral direction.
[0213] The first pneumatic drive component 406 includes a first pneumatic cylinder, which is connected to the frame 401. The first pneumatic cylinder is provided with a first pneumatic rod 40602, and the other end of the second pneumatic rod 40502 is connected to the mounting plate 40202.
[0214] The aforementioned first pneumatic cylinder is connected to multiple pneumatic pipes, which in turn connect to a pneumatic pump, a housing, and multiple check valves, sequence valves, and relief valves. A complete pneumatic drive system drives the first pneumatic rod 40602 to achieve reciprocating linear motion within the first pneumatic cylinder. The position adjustment of the aforementioned clamping assembly 404 is achieved through the movement of the first pneumatic rod 40602.
[0215] It is worth noting that multiple infrared sensors are installed on the clamping station. By detecting the real-time status of the station through the sensors, the main controller controls the first pneumatic drive unit 406 and the second pneumatic drive unit 405 to achieve precise and orderly driving, thereby realizing the clamping of the workpiece.
[0216] In some actual operations, the first pneumatic rod 40602 may experience slight vibration or other instability under the pressure in the first pneumatic cylinder. In order to further improve the driving stability of the first pneumatic drive component 406, a limit block 407 is provided on the frame 401. A limit hole is provided on the limit block 407, and a first limit rod is sleeved in the limit hole. The first limit rod 40701 is connected to the mounting plate 40202.
[0217] The aforementioned limiting block 407 and the aforementioned first limiting rod 40701 are in sliding engagement, which ensures that the moving accuracy of the aforementioned clamping component 404 will not be reduced due to factors such as unstable air pressure or vibration of the device itself during horizontal linear reciprocating movement in the forward and backward direction.
[0218] It is worth noting that the inner wall of the aforementioned limiting hole and the outer wall of the aforementioned first limiting rod 40701 are both smooth, which can reduce friction and improve the efficiency of the aforementioned clamping assembly 404 in moving horizontally.
[0219] The mounting plate 40202 has a vertical protrusion 40203 at its front end, and the connecting block 40301 has a vertical groove corresponding to the vertical protrusion 40203 at its rear end. The vertical protrusion 40203 and the vertical groove slide in engagement. This sliding engagement ensures the stability of the mounting plate 40202 relative to the connecting block 40301 during relative movement, and prevents the mounting plate 40202 and the connecting block 40301 from detaching or shifting. This further improves the stability of the second pneumatic drive 405 driving the clamping assembly 404 to move vertically.
[0220] The connecting block 40301 is provided with a support plate 40503. The support plate 40503 has a through hole. The second pneumatic rod 40502 passes through the through hole. The outer wall of the second pneumatic rod 40502 and the inner wall of the through hole are both smooth. The second pneumatic rod 40502 is slidably connected to the through hole.
[0221] A spring 40505 is sleeved on the second pneumatic rod 40502, and a support ring 40504 is provided at the lower end of the second pneumatic rod 40502. The two ends of the spring 40505 abut against the lower end of the support plate 40503 and the upper end of the support ring 40504, respectively. The spring 40505 is always in a compressed state, and the elastic force of the spring 40505 acts on the second pneumatic rod 40502 and the connecting block 40301, which can improve the stability of the second pneumatic rod 40502 in the vertical direction to a certain extent.
[0222] Meanwhile, in order to further improve the stability of the second pneumatic rod 40502 in the vertical direction, a second limiting rod 40506 is provided on one side of the second pneumatic rod 40502. The upper end of the second limiting rod 40506 is connected to the second pneumatic cylinder, and the lower end of the second limiting rod 40506 is slidably connected to the connecting block 40301.
[0223] Specifically, the connecting block 40301 is provided with a sliding hole, the second limiting rod 40506 is slidably engaged with the sliding hole, and the outer wall of the second limiting rod 40506 and the inner wall of the sliding hole are both smooth, which can further improve the stability of the second pneumatic rod 40502 moving in the vertical direction. Example 6
[0224] Please refer to Figures 24-27 This embodiment provides a strip spring production line equipment. The aforementioned forward and backward moving component 501 includes a first positioning part 50103. The first positioning part 50103 is slidably provided with a first sliding part 50102 for forward and backward movement. The first positioning part 50103 is also provided with a first power part 50101 that drives the first sliding part 50102 to move.
[0225] The aforementioned longitudinal lifting assembly 502 includes a second positioning part 50203 disposed on the aforementioned first sliding part 50102. The aforementioned second positioning part 50203 is slidably provided with a second sliding part 50202 for longitudinal lifting. The aforementioned second positioning part 50203 is provided with a second power part 50201 for driving the aforementioned second sliding part 50202 to lift longitudinally.
[0226] The aforementioned rotating assembly 503 includes a connecting seat 50301 rotatably disposed on the aforementioned second sliding portion 50202. The connecting seat 50301 is used for longitudinal rotation. The aforementioned second sliding portion 50202 is also provided with a third power unit 50302 that drives the connecting seat 50301 to rotate.
[0227] The pneumatic clamping assembly 504 is disposed on the connecting seat 50301.
[0228] In actual processing, the spring is inserted into the window of the strip, and a single spring (which is V-shaped) is clamped by the pneumatic clamping assembly 504. When clamping the spring, the opening of the spring faces downward, and the two arms of the spring are arranged front and back respectively. The first power unit 50101 drives the first sliding part 50102 to slide back and forth, indirectly realizing the back and forth sliding of the spring clamped on the pneumatic clamping assembly 504. The second power unit 50201 drives the second sliding part 50202 to slide longitudinally, indirectly realizing the longitudinal sliding of the spring clamped on the pneumatic assembly. The third power unit 50302 drives the connecting seat 50301 to flip, indirectly realizing the adjustment of the opening orientation of the spring. Through the above adjustment, the single spring can be hung into the window of the strip (after the spring is hung, the pneumatic finger is kept in a state of tightening the spring until the upper point welding is completed). This invention enables fully mechanized operation of a single spring, adjusting each component to ensure the same flipping angle each time. Compared to traditional manual operation, it is more precise (the path for the spring to be inserted into the strip window is very narrow, and manual operation cannot guarantee that it can be inserted into the same position each time) and more efficient (efficiency decreases after long-term manual work).
[0229] In some embodiments of the present invention, the first positioning part 50103 is provided with two concave blocks 505 symmetrically arranged, the two concave blocks 505 being distributed on the front and rear sides of the first positioning part 50103 respectively, and the first sliding part 50102 is provided with a sliding strip 506 that simultaneously slides with the grooves of the two concave blocks 505.
[0230] In the above embodiment, the sliding engagement of the two concave blocks 505 and the sliding strip 506 not only has a guiding function, but also reduces the load on the first power unit 50101 (by distributing a portion of the weight of the first sliding part 50102 to the first positioning part 50103), making the forward and backward sliding of the first sliding part 50102 more stable.
[0231] In some embodiments of the present invention, both inner sides of the concave block 505 are inclined toward their inner sides.
[0232] In the above embodiment, a groove with a large bottom diameter and a small outer diameter is formed on the inner side of the concave block 505. The groove slides in conjunction with the sliding bar 506, so that the outer side of the groove has a clamping effect on the sliding bar 506, making the connection between the first sliding part 50102 and the first positioning part 50103 more stable.
[0233] In some embodiments of the present invention, the second positioning part 50203 is provided with a slide rail in the longitudinal direction, and the second sliding part 50202 is provided with a sliding groove that slides and engages with the slide rail.
[0234] In the above embodiments, the sliding engagement of the slide rail and the sliding groove enables the second sliding part 50202 to slide directionally on the second positioning part 50203, thereby improving the stability of the second sliding part 50202 sliding on the second positioning part 50203.
[0235] In some embodiments of the present invention, the connecting seat 50301 is provided with a rotating shaft 507, which is rotatably engaged with the second sliding part 50202.
[0236] In the above embodiment, the rotating shaft 507 is inserted into the second sliding part 50202, and the rotational engagement of the rotating shaft 507 and the second sliding part 50202 realizes the rotational connection of the connecting seat 50301 and the second sliding part 50202.
[0237] In some embodiments of the present invention, the aforementioned rotating shaft 507 and the aforementioned second sliding portion 50202 are connected by a bearing 508.
[0238] In the above embodiment, the bearing 508 is an important component in modern mechanical equipment. Its main function is to support the rotating mechanical body, reduce the coefficient of friction during its movement, and ensure its rotational accuracy. The rotating shaft 507 passes through the inner ring of the bearing 508, and the second sliding part 50202 is connected to the outer ring of the bearing 508. The bearing 508 realizes the rotational engagement of the rotating shaft 507 and the second sliding part 50202, which can reduce the friction between the rotating shaft 507 and the second sliding part 50202. On the one hand, it avoids wear on the rotating shaft 507 or the second sliding part 50202, thus having a noise reduction function. On the other hand, it can reduce the load on the third power unit 50302.
[0239] In some embodiments of the present invention, a mounting base 50303 is provided above the connecting base 50301, the mounting base 50303 is connected to the second sliding part 50202, and the third power part 50302 is disposed on the mounting base 50303.
[0240] In the above embodiment, the third power unit 50302 on the mounting base 50303 can drive the longitudinal rotation of the connecting base 50301, indirectly realizing the longitudinal flipping of the pneumatic clamping assembly 504, realizing the adjustment of the spring opening orientation, and facilitating the insertion of the spring into the strip window.
[0241] In some embodiments of the present invention, the pneumatic clamping assembly 504 is a pneumatic gripper, which includes two gripping arms that clamp and cooperate with each other, and the two gripping arms are laterally distributed.
[0242] In the above embodiments, the two gripping arms of the pneumatic gripper engage laterally. The pneumatic gripper has the advantages of fast pneumatic response and simple operation, which facilitates the automated control of the pneumatic gripper.
[0243] In some embodiments of the present invention, the first power unit 50101 and the second power unit 50201 are both cylinders, and the third power unit 50302 is a hydraulic telescopic rod.
[0244] In the above embodiments, the hydraulic telescopic rod, as the third power unit 50302, has the advantages of being lightweight, small in size, having low motion inertia, and fast response speed.
[0245] In some embodiments of the present invention, the second positioning part 50203 and the first sliding part 50102, and the connecting seat 50301 and the second sliding part 50202 are detachably connected by bolts.
[0246] In the above embodiments, the bolt connection method can realize the disassembly or installation of the front and rear moving component 501, the longitudinal lifting component 502 and the rotating component 503, which facilitates targeted maintenance and repair of any one of the three components.

The two movable sliders 604 cause the mounting bracket 6017 to move relative to each other, thereby causing the electrodes 603 to move relative to each other, achieving spot welding of the spring. The synchronous gear 605 synchronizes the two electrodes 603, applying pressure to the weld points on both sides of the spring simultaneously. A vertical moving mechanism drives the welding mechanism to move up and down to adapt to the varying welding positions of different batches of strip springs, further improving the dimensional deviation of the weld point positions between different batches of springs. A horizontal moving mechanism drives the welding mechanism to move horizontally, allowing the welding device to move along the strip direction to make room, hook in the spring, and then move back for welding, achieving horizontal clearance and precise positioning of the welding device. The welding device of this invention features balanced welding pressure, the ability to adjust the welding point position vertically to adapt to the welding positions of different batches of strip springs, and horizontal movement, achieving high horizontal clearance fit and accurate welding positioning.
[0251] The following will further describe a synchronous pressure welding apparatus in this exemplary embodiment.
[0252] In one embodiment of this invention, the welding mechanism is connected to the vertical moving mechanism via a first slide rail 6018, and the vertical moving mechanism is connected to the horizontal moving mechanism via a second slide rail 6019. The welding mechanism includes a fixed base 601, a pressurizing cylinder 602, a synchronous gear 605 assembly, and two electrodes 603. The two electrodes 603 are disposed opposite each other on two mounting brackets 6017. Specifically, the two electrodes 603 are disposed on opposite sides of the bottom of the mounting brackets 6017, and are detachably mounted on the mounting brackets 6017 for easy replacement. It should be noted that when replacing the electrodes 603, a special tooling needs to be fixed on the electrode 603 mounting connector 6021 to ensure the electrode 603... The positioning is accurate; two mounting brackets 6017 are respectively connected to two movable sliders 604, and the inner sidewalls of the two movable sliders 604 are connected to the sidewall of the fixed base 601 through the third slide rail 6020. The aforementioned pressurizing cylinder 602 is connected to one of the movable sliders 604, driving the movable slider 604 to move on the third slide rail 6020; the aforementioned synchronous gear 605 assembly includes a synchronous gear 605 and two upper and lower racks 606 meshing with the synchronous gear 605. The aforementioned synchronous gear 605 is mounted on the front sidewall of the fixed base 601 through a gear mounting block 6024. The gear shaft of the aforementioned synchronous gear 605 passes through the synchronous gear 605 and the mounting block 6024 and is connected. The two racks 606 are respectively connected to the two movable sliders 604 through connectors 6021.
[0253] As an example, an adjusting screw 6025 extends laterally through the mounting block 6024. The two ends of the adjusting screw 6025 pass through the two ends of the fixing seat 601 and are fastened together by nuts 6026. The left and right movement of the mounting block 6024 can be adjusted by adjusting the adjusting screw 6025, thereby adjusting the left and right position of the gear. After adjustment, it is fixed by nuts 6026, ultimately adjusting the welding center point between the two electrodes 603 during welding, making the position adjustment during the welding process more flexible.
[0254] As an example, the rack 606 located at the lower end of the synchronizing gear 605 is connected to the movable slider 604 via a rectangular connector 6021. The rack 606 located at the upper end of the synchronizing gear 605 is connected to another movable slider 604 via an inverted L-shaped connector 6021. The rack 606 is connected to the bottom surface of the horizontal axis of the L-shaped connector 6021, and the vertical axis of the L-shaped connector 6021 is connected to the movable slider 604. It should be noted that both racks 606 are bolted to the connectors 6021. Specifically, the ends of the racks 606 have multiple threaded holes, and the connectors 6021 have corresponding connecting grooves. Bolts pass through the threaded holes and connecting grooves to connect the two. The rack 606 can move left and right on the connectors 6021. When movement is needed, the bolts can be loosened; after movement, the bolts can be tightened, so that when the gear moves left or right, the rack 606 moves simultaneously with the gear.
[0255] In one specific implementation, the pressurizing cylinder 602 drives the connected movable slider 604 to move, and the rack 606 connected to the movable slider 604 moves accordingly, thereby driving the synchronous gear 605 to rotate. The upper rack 606 moves with the rotation of the synchronous gear 605, thereby driving the other movable slider 604 to move, so that the two movable sliders 604 move relative to each other, realizing the precise welding of the spring welding point by the two electrodes 603. The synchronous gear 605 assembly synchronizes the welding action and welding pressure of the two electrodes 603, realizing the equalization of welding pressure.
[0256] In one embodiment of this invention, threaded screws 6014 are inserted inside the two movable sliders 604. The threaded screws 6014 support and guide the movable sliders 604. A welding pressure sensor 6015 is provided at the end of the movable slider 604 away from the pressurizing cylinder 602. The welding pressure sensor 6015 is used to detect the welding pressure during welding. Welding pressure is one of the important parameters of welding. The synchronous pressurizing welding device is designed with a pressure sensor to monitor the welding pressure in real time. It should be noted that the pressure sensor needs to be calibrated regularly, and the calibration fixture is also completed by a special fixture. In this embodiment, the welding pressure sensor 6015 is a Kistler A pressure sensor.
[0257] In one embodiment of this invention, a displacement sensor 6016 is provided on the top of the connector 6021. The displacement sensor 6016 is a grating ruler; in this embodiment, a Heidenhain grating ruler or LS-C is used. The displacement sensor 6016 is used to monitor the horizontal movement distance of the moving slider 604 and to transmit precise welding displacement information of the electrode 603.
[0258] In one embodiment of this invention, the electrode 603 is made of beryllium copper. It is manufactured using imported beryllium copper (CuCoBe) material, which is highly conductive and wear-resistant. The shape and dimensions of electrode 603 are the same as those used in existing equipment, ensuring no damage to the strip and spring during welding, and also facilitating the management of spare parts.
[0259] In one embodiment of this invention, a protective baffle 6023 is installed on the outer front end of the welding mechanism, which serves to prevent dust and improve aesthetics.
[0260] In one embodiment of this invention, the vertical moving mechanism includes a servo motor 607, a ball screw jack 608, and a fixed plate 6022. The servo motor 607 is connected to the ball screw jack 608, driving the ball screw jack 608 to move up and down. A movable block 609 is fitted onto the ball screw jack 608, and the movable block 609 is fixedly connected to the fixed base 601. Specifically, the fixed plate 6022 has a through hole, and one end of the movable block 609 passes through the through hole and connects to the fixed base 601. The second slide rail 6019 is provided on... On the fixed plate 6022, the rear end face of the fixed seat 601 is slidably connected to the second slide rail 6019. Specifically, there are two second slide rails 6019, which are respectively arranged on both sides of the same end face of the fixed plate 6022. The rear end face of the fixed seat 601 is slidably connected to the second slide rail 6019 on both sides. As the ball screw jack 608 rises and falls, the fixed seat 601 rises and falls on the second slide rail 6019, realizing vertical displacement to accommodate the changes in the welding point position and dimensional deviation of different batches of springs, ensuring accurate positioning of the welding points of each batch of springs, and improving welding efficiency and welding effect.
[0261] In one embodiment of this invention, the top of the fixed plate 6022 is connected to a slide rail seat 6010, and the first slide rail 6018 is disposed within the slide rail seat 6010; the horizontal moving mechanism includes a mounting base 6011 and a moving cylinder 6012, the mounting base 6011 is slidably connected to the first slide rail 6018, the moving cylinder 6012 is fixed to the side end face of the slide rail seat 6010, and the telescopic rod of the moving cylinder 6012 is connected to the mounting base 6011 through a limiting plate 6013, the limiting plate 6013 is disposed on the front end face of the mounting base 6011, and plays a limiting role for the moving cylinder 6012.
[0262] In one specific implementation, the mounting base 6011 remains fixed, while the moving cylinder 6012 operates, extending and retracting horizontally. This causes relative sliding between the slide rail base 6010 and the first slide rail 6018 and the mounting base 6011. The slide rail base 6010 moves the bottom mounting plate horizontally, thereby moving the fixed base 601 horizontally. This allows the welding device to move along the strip direction to make room even in confined spaces when hanging springs, hooking in the springs and then moving back to weld. This flexible arrangement completes the tooling for hooking springs into the strip window and welding them, achieving horizontal clearance and precise positioning of the welding device.
[0263] The working principle and beneficial effects of this invention embodiment are as follows: During welding, the mounting base 6011 is first driven to move backward in the horizontal direction by the moving cylinder 6012. The mounting base 6011 drives the fixing plate 6022 and the fixing base 601 to move backward simultaneously, so that the welding device moves along the strip direction to make room. After the spring is engaged, it moves back to perform welding, thus achieving horizontal positioning of the welding device. Next, the pressure cylinder 602 drives one moving slider 604 to move, and at the same time, the synchronous gear 605 assembly drives the other moving slider 604 to move. The two moving sliders... The mounting bracket 6017 moves relative to the spring, which in turn moves the electrode 603, enabling spot welding and precise positioning of the spring. Synchronization of the two electrodes 603 is achieved via a synchronous gear 605, applying pressure to the weld points on both sides of the spring simultaneously, ensuring balanced welding pressure. When replacing springs from different batches, a servo motor 607 drives a ball screw jack 608 to move up and down, thereby shifting the welding mechanism vertically to accommodate changes in the welding position of different batches of strip springs, further improving the dimensional deviation of the weld point positions between different batches. The welding device of this invention provides balanced welding pressure, allows for vertical adjustment of the welding point position to adapt to different batches of strip springs, and enables horizontal movement, achieving high horizontal clearance and accurate welding positioning.

The bottom of the fixing component 701 is provided with a left moving component 702 and a right moving component that move in opposite directions. The left moving component 702 is provided with a first pneumatic finger 703 and a first pneumatic ejector pin 704. The right moving component is provided with a second pneumatic finger 705 and a second pneumatic ejector pin 706. The second pneumatic finger 705 is symmetrical to the first pneumatic finger 703, and the second pneumatic ejector pin 706 is symmetrical to the first pneumatic ejector pin 704. As shown in the figure, the spring centering and height control device provided in this embodiment of the invention mainly consists of seven parts: a fixed component 701, a left moving component 702, a right moving component, a first pneumatic finger 703, a first pneumatic ejector pin 704, a second pneumatic finger 705, and a second pneumatic ejector pin 706. The fixed component 701 is used to fix the spring centering and height control device to the processing table. The strip and spring sheet held by the clamp on the processing table pass under the spring centering and height control device. The left moving component 702 is installed on the left side of the fixed component 701 and is used to drive the first pneumatic finger 703 and the first pneumatic ejector pin 704 to move to the right. The right moving component is installed on the right side of the fixed component 701 and is used to drive the second pneumatic finger 705 and the second pneumatic ejector pin 706 to move to the left. The first pneumatic finger 703 and the second pneumatic finger 705 are used for centering and clamping the spring sheet. The first pneumatic ejector pin 704 and the second pneumatic ejector pin 706 are used to squeeze the arched part of the spring sheet and adjust the height and curvature of the arched part.
[0265] The left moving component 702 is connected to the bottom left side of the fixed component 701, and the right moving component is connected to the bottom right side of the fixed component 701. The first pneumatic finger 703 and the first pneumatic ejector pin 704 are both installed at the right end of the left moving component 702, and the second pneumatic finger 705 and the second pneumatic ejector pin 706 are both installed at the left end of the right moving component. The first pneumatic finger 703 and the second pneumatic finger 705 are symmetrical left and right, as are the first pneumatic ejector pin 704 and the second pneumatic ejector pin 706, which work together to adjust the double-spring strip (i.e., the strip has spring plates on both sides, such as...). Figure 36 ) spring sheet.
[0266] In actual use, before the spring centering and height control device of this embodiment is activated, the left moving component 702 is located on the far left and the right moving component is located on the far right. There is a gap between the first pneumatic finger 703 and the second pneumatic finger 705, and between the first pneumatic ejector pin 704 and the second pneumatic ejector pin 706. Then, the fixture on the processing table moves to the gap with the double spring strip. Then, the left moving component 702 moves to the right and the right moving component moves to the left, driving the first pneumatic finger 703 and the first pneumatic ejector pin 704, the second pneumatic finger 705 and the second pneumatic ejector pin 706 to move closer to the center. The first pneumatic finger 703 and the second pneumatic finger 705 both use electrical equipment in the prior art. After they move closer, the first pneumatic finger 703 clamps the spring plate on the left and the second pneumatic finger clamps the spring plate on the right. During the clamping process, the spring plate is centered and aligned, and kept in a vertical state. The first pneumatic ejector pin 704 and the second pneumatic ejector pin 706 both use existing electrical equipment. After the spring sheet is clamped, the first pneumatic ejector pin 704 presses against the arched part of the spring sheet on the left side, and the second pneumatic ejector pin 706 presses against the arched part of the spring sheet on the right side. By coordinating the adjustment of the height and curvature of the arched part, the accuracy of the next welding step is improved.

Through the technical solution of this embodiment, the left cylinder 70201, under the control of the computer in the prior art, drives the piston rod to move left and right. Due to the restriction of the slider at the top of the left slide table 70203 and the groove at the bottom of the left guide rail 70202, the slider moves left and right along the groove, thereby realizing the precise left and right movement of the first pneumatic finger 703 and the first pneumatic ejector pin 704. The technology is mature and the operation is stable and reliable.
[0268] In some embodiments of the present invention, the right moving component includes a right cylinder 70301, a right guide rail 70302, and a right slide 70303.

The piston rod of the right cylinder 70301 is connected to the right slide 70303. The slider at the top of the right slide 70303 is embedded in the groove at the bottom of the right guide rail 70302. The second pneumatic finger 705 and the second pneumatic ejector pin 706 are both fixedly installed at the left end of the right slide 70303. Through the technical solution of this embodiment, the right cylinder 70301, under the control of the computer in the prior art, drives the piston rod to move left and right. Due to the restriction of the slider at the top of the right slide table 70303 and the groove at the bottom of the right guide rail 70302, the slider moves left and right along the groove, thereby realizing the precise left and right movement of the second pneumatic finger 705 and the second pneumatic ejector pin 706. The technology is mature and the operation is stable and reliable.

[0270] In some embodiments of the present invention, the first pneumatic finger 703 includes a pneumatic clamping body connected to the left moving component 702, and a gripper is provided at the right end of the pneumatic clamping body. The first pneumatic finger 703 adopts a flat-opening pneumatic finger or a V-shaped pneumatic finger in the prior art, mainly composed of a pneumatic clamping body and a gripper. The gripper is connected to the pneumatic clamping body, and the pneumatic clamping body is screwed to the left slide 70203 of the left moving component 702.

The technology is mature and has good performance. It should be noted that the second pneumatic finger 705 can also adopt the same structure as the first pneumatic finger 703.
[0271] In some embodiments of the present invention, the end of the gripper is provided with an abutment surface 703021. A vertical abutment surface 703021 is provided at the right end of the gripper. The gripper of the second pneumatic finger 705 can also adopt the same structure.

[0272] In some embodiments of the present invention, the first pneumatic ejector pin 704 includes a pneumatic clamping arm 70401 connected to the left moving component 702, and an abutment member 70402 is provided at the right end of the pneumatic clamping arm 70401. The first pneumatic ejector pin 704 mainly consists of two parts: the pneumatic clamping arm 70401 and the abutment member 70402.

The pneumatic clamping arm 70401 is a pneumatic push rod in the prior art, and an "L"-shaped clamping arm is installed at the end of the push rod. The abutment member 70402 is connected to the clamping arm. The second pneumatic ejector pin 706 can also adopt the same structure as the first pneumatic ejector pin 704. Through the technical solution of this embodiment, by controlling the movement of the pneumatic clamping arm 70401, the abutment member 70402 is controlled to abut against the spring sheet.

Through the technical solution of this embodiment, the first pneumatic push pin 704 has a certain elasticity, which can be used to adjust the arch height of the spring sheet, and can also be used to slightly press the spring sheet to prevent the spring sheet from jumping up when welding the weld point, resulting in better performance.
[0274] In some embodiments of the present invention, the aforementioned fixing component 701 includes a plate frame 70101 and a support plate 70102 connected to each other. The support plate 70102 is connected to the left moving component 702 and the right moving component. As shown in the figure, the plate frame 70101 is "axe-shaped," and its right end is fixedly connected to the mounting bracket of the worktable.

[0276] Please refer to Figures 37-39 This embodiment provides a strip spring production line equipment. The spring curvature height measuring unit includes a measuring bracket 801. The measuring bracket 801 is provided with a first clamping member 802 and a second clamping member 803 opposite to each other. The measuring bracket 801 is provided with a driving component 804 for driving the first clamping member 802 and the second clamping member 803 to clamp and cooperate. The measuring bracket 801 is provided with a first micrometer 805. The measuring end of the first micrometer 805 is located between the first clamping member 802 and the second clamping member 803.
[0277] The principle of this invention: The curvature of the springs on the grid directly affects its clamping degree on the fuel rods, thus affecting its function. Currently, the spring curvature height is measured manually by random sampling. This inspection method can only obtain the pass rate of the improved grid with a certain probability, and cannot guarantee the pass rate of each improved grid. Moreover, the measured value of curvature height detected by manual sampling is also subject to human measurement error. In this embodiment of the invention, the driving component 804 drives the first clamping member 802 and the second clamping member 803 to open and close, thereby clamping the strip with spring plates to be measured. Then, the first micrometer 805 is used to measure the curvature of the spring plates on one side of the strip, thereby turning manual measurement into automated measurement, avoiding the accuracy error caused by manual measurement, reducing labor costs, improving inspection time, turning random sampling into full inspection, and improving overall measurement efficiency.
[0278] The measuring bracket 801 is equipped with a fastening block, which is threadedly connected to the measuring bracket 801. Before actual measurement, the first micrometer 805 is adjusted to a suitable position between the first clamping member 802 and the second clamping member 803, ensuring that when the first clamping member 802 and the second clamping member 803 clamp the strip to be measured, the measuring end of the first micrometer 805 is exactly in contact with the spring sheet measuring point. Then, the fastener is tightened with screws to determine the position of the first micrometer 805. Subsequently, a person can hold the strip and feed it between the first clamping device and the second clamping device for spring sheet measurement, i.e., manual feeding. Alternatively, manual feeding can be used in conjunction with a feeding assembly (the feeding assembly includes a feeding bracket, which is interactively equipped with a feeding slider, and the feeding block is equipped with a screw). A servo motor drives the screw to rotate, and the feeding block is equipped with a groove to supply the strip. Alternatively, a robotic arm can be used for feeding. When the drive assembly 804 is activated, it opens a certain gap between the first clamping member 802 and the second clamping member 803, placing the strip in the gap (this process can be performed by a robotic arm, manually, or using a feeding assembly). Subsequently, the drive assembly 804 drives the first clamping member 802 and the second clamping member 803 to close, clamping the strip assembly. At this time, the first micrometer 805 measures and reads the value, completing the value measurement of one spring sheet. This process is continuously repeated to complete subsequent measurements. This design transforms traditional manual sampling inspection into automated measurement, reducing human factors, improving measurement accuracy, reducing labor costs, and accelerating the measurement speed of spring curvature.
[0279] In some embodiments of the present invention, the measuring bracket 801 is provided with a second micrometer 806, the measuring end of the second micrometer 806 passing through the second clamping member 803 and disposed opposite to the first micrometer 805.
[0280] In the above embodiment, the measuring bracket 801 is provided with a second fastening block for fixing the second micrometer 806. Both fastening blocks are threadedly connected to the measuring bracket 801. Before actual measurement, the first micrometer 805 and the second micrometer 806 are adjusted into the first clamping member 802 and the second clamping member 803 to ensure that when the first clamping member 802 and the second clamping member 803 clamp the strip to be measured, the measuring ends of the first micrometer 805 and the second micrometer 806 are exactly abutting the measuring points on both sides of the spring sheet, respectively. Then, the two fasteners are tightened with screws to determine the positions of the first micrometer 805 and the second micrometer 806.
