Description

Technical Field

[0001] This invention relates to the field of civil defense door technology, specifically to a tooling for assembling and shaping steel pipe shafts for civil defense equipment door panels. Background Technology

[0002] Civil defense doors are the doors at the entrances and exits of civil defense projects. Civil defense doors are classified in a relatively clear way, including ordinary single and double-leaf protective airtight doors and airtight doors, as well as single and double-leaf protective airtight doors and airtight doors with movable thresholds, etc. Civil defense doors are generally opened by rotating, so a steel pipe shaft for the door leaf is required as a rotating part.

[0003] Currently, steel pipe shafts are generally assembled by welding. To prevent the steel pipes in the middle of the shaft from shifting or tilting during welding, the dimensions need to be measured before welding to determine the welding and fixing position.

[0004] Therefore, in the existing technology, the welding and assembly of steel pipe shafts takes a lot of time due to the initial measurement, which is time-consuming and labor-intensive, reducing the production efficiency of steel pipe shafts for civil defense equipment doors. At the same time, manual welding may cause misalignment during welding, resulting in the middle steel pipe of the steel pipe shaft being misaligned or skewed, which may require rework, which is time-consuming and labor-intensive, reducing production efficiency. If rework is not possible, it will result in material waste and increase production costs. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a standardized tooling for assembling steel pipe shafts for civil defense equipment doors, which solves the problems of time-consuming and labor-intensive welding of steel pipe shafts for civil defense equipment doors, and the tendency for manual welding to cause misalignment or skewing.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a steel pipe shaft assembly and shaping fixture for a civil defense equipment door leaf, comprising a base, the base being connected to a driving mechanism, the base being connected to a shaping mechanism, stabilizing mechanisms being fixedly connected to both the left and right sides of the shaping mechanism, and a steel pipe rotating shaft being slidably connected to the top of the base;

[0007] The driving mechanism includes a moving groove, a moving plate slidably connected inside the moving groove, two inner rods fixedly connected to the left side of the moving plate, an outer column fixedly connected to the inner left side of the moving groove, a spring fixedly connected inside the outer column, a limit block fixedly connected to the other end of the spring, multiple slide bars fixedly connected to the bottom of the moving plate, and multiple sliding grooves provided on the inner wall of the bottom end of the moving groove, with the slide bars slidably connected inside the sliding grooves.

[0008] Preferably, the shaping mechanism includes two folding frames and two mounting frames. The inner left and right ends of the folding frames are rotatably connected to connecting rods. The bottom of each connecting rod is rotatably connected to the inside of the mounting frame on the side away from the rotating axis of the steel pipe. Each side of the mounting frame is slidably connected to a sliding rod. A limit plate is fixedly connected to the opposite side of the sliding rod. A tension spring is fixedly connected to the opposite side of the limit plate. A clamping plate is fixedly connected to the opposite side of the sliding rod. Two sliders are fixedly connected to the bottom of the front folding frame. A sliding groove is provided inside the top of the moving plate and the base. The sliders are slidably connected inside the sliding groove.

[0009] Preferably, the stabilizing mechanism includes two mounting strips and two slots. A fixing cylinder is fixedly connected to the front side of the mounting strip. A second spring is fixedly connected inside the fixing cylinder. A sliding plate is fixedly connected to the other end of the second spring. A round head is fixedly connected to the opposite side of the sliding plate. The two slots are fixedly connected to the left and right sides of the front mounting frame, respectively, and the slots engage with the round heads.

[0010] Preferably, the limiting block is slidably connected to the inside of the outer column, and the moving groove is located inside the left side of the base.

[0011] Preferably, a sliding rod is slidably connected inside the opposite side of the mounting frame, and a stop plate is fixedly connected to the bottom of the sliding rod.

[0012] Preferably, a pressure spring is fixedly connected to the top of the abutment plate, the top of the pressure spring is fixedly connected to the bottom outer side of the mounting frame, and the pressure spring is disposed outside the sliding rod.

[0013] Preferably, the tension spring is disposed outside the sliding rod, and the opposite side of the tension spring is fixedly connected to the outside of the mounting frame.

[0014] Preferably, the bottom left side of the rear folding frame is rotatably connected to the top rear side of the movable plate, the bottom right side of the rear folding frame is fixedly connected to the top right side of the base, and a round handle is fixedly connected to the top of the sliding rod.

[0015] Preferably, the two mounting strips are fixedly connected to the left and right sides of the mounting frame respectively, and the sliding plate is slidably connected inside the fixed cylinder.

[0016] Preferably, the top left and right sides of the steel pipe rotating shaft are respectively positioned between four clamping plates, and mounting holes are provided at each of the four corners of the steel pipe rotating shaft.

[0017] Working Principle: First, because the top right side of the moving plate and the top left side of the base are both curved, the base of the steel pipe rotating shaft can be pressed between the moving plate and the base. At this time, under the action of spring one inside the outer column, a force is applied to the limiting block outward, which can then be transmitted to the inner rod, thereby squeezing the base of the steel pipe rotating shaft tightly. The movement of the moving plate can drive the left side of the folding frame to move to the left, which can drive the connecting rod to rotate, thus keeping the mounting frame always in the middle position at the bottom of the steel pipe rotating shaft. Then, the front folding frame is moved to the rear, which moves the left mounting frame to the top of the bottom of the steel pipe rotating shaft and into contact with the right mounting frame. At this time, the round head can be pressed into the inside of the fixed cylinder under the action of the mounting frame. When the round head moves to the position of the slot, under the action of spring two... The bottom can engage the round head with the slot, thereby increasing the stability when the two mounting frames are connected. The positions of the two plates on the top of the steel pipe rotating shaft can be adjusted according to actual needs. Then, the two plates of the steel pipe rotating shaft are placed inside the clamping plate. Under the action of the tension spring, the limiting plate is pulled towards the center, causing it to move towards the center, which in turn moves the clamping plate towards the center, clamping the two plates on the steel pipe rotating shaft. This stabilizes the plates on the steel pipe rotating shaft. The steel pipe in the middle of the rotating shaft is then placed between the two plates. Since the plates are vertical and the steel pipe is cylindrical, as long as the steel pipe is tightly attached to the plates, there will be no displacement. Welding can then be performed, allowing for shaping without measuring multiple dimensions, and providing high stability, thus preventing displacement during welding.

[0018] This invention provides a standardized tooling for assembling steel pipe shafts for civil defense equipment doors. It has the following beneficial effects:

[0019] 1. This invention uses a moving plate to clamp and stabilize the bottom of the steel pipe shaft. After the position of the clamping plate is determined, the two side plates of the steel pipe shaft can be placed inside the clamping plate. This allows the position to be determined without measurement, and welding can then be performed. This eliminates the need for dimensional measurement and thus improves the production efficiency of steel pipe shafts for civil defense equipment doors.

[0020] 2. This invention uses a movable plate to adjust and clamp the base according to its size. The mounting frame is always positioned in the center of the bottom of the steel pipe shaft. The clamping plate also helps to shape the two plates of the steel pipe shaft, eliminating the need for manual handling during welding. This prevents worker errors from causing the steel pipe in the middle of the shaft to shift or tilt, thus avoiding rework due to tilted steel pipe. This saves time and effort, improves production efficiency, avoids material waste, and reduces costs. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example:

[0033] Please see the appendix Figure 1 -Appendix Figure 10 This invention provides a tooling for assembling and shaping steel pipe shafts for civil defense equipment doors, including a base 1, which is connected to a driving mechanism 2 and a shaping mechanism 3. The left and right sides of the shaping mechanism 3 are fixedly connected to stabilizing mechanisms 4, and the top of the base 1 is slidably connected to a steel pipe rotating shaft 5.

[0034] The base 1 provides the installation position, and the driving mechanism 2 is used to move and clamp the steel pipe rotating shaft 5. The shaping mechanism 3 is used to position and weld the steel pipe rotating shaft 5, and the stabilizing mechanism 4 can also be used to stabilize it.

[0035] The driving mechanism 2 includes a moving groove 201, a moving plate 202 is slidably connected inside the moving groove 201, two inner rods 203 are fixedly connected to the left side of the moving plate 202, an outer column 204 is fixedly connected to the inner left side of the moving groove 201, a spring 205 is fixedly connected inside the outer column 204, a limit block 206 is fixedly connected to the other end of the spring 205, a plurality of slide bars 207 are fixedly connected to the bottom of the moving plate 202, a plurality of slide grooves 208 are provided on the inner wall of the bottom end of the moving groove 201, and the slide bars 207 are slidably connected inside the slide grooves 208.

[0036] The sliding groove 201 provides sliding space for the moving plate 202. At the same time, the inner rod 203 is connected to the outer column 204. The spring 205 pushes the limiting block 206 to the outside of the outer column 204, which in turn drives the inner rod 203 to move outward, thereby pushing the moving plate 202 to move. The moving plate 202 moves to the right, thereby squeezing and clamping the steel pipe rotating shaft 5. The sliding strip 207 slides inside the sliding groove 208, thereby restricting the movement trajectory of the moving plate 202 and preventing the moving plate 202 from moving out of the sliding groove 201.

[0037] Please see the appendix Figure 4 -Appendix Figure 10 The shaping mechanism 3 includes two folding frames 301 and two mounting frames 303. The left and right ends of the inner side of the folding frame 301 are rotatably connected to the connecting rods 302. The bottom of the two connecting rods 302 are rotatably connected to the inside of the mounting frame 303 on the side away from the rotating shaft 5 of the steel pipe. The left and right sides of the mounting frame 303 are slidably connected to the sliding rods 304. The opposite side of the sliding rods 304 is fixedly connected to the limiting plate 305. The opposite side of the limiting plate 305 is fixedly connected to the tension spring 306. The opposite side of the sliding rods 304 is fixedly connected to the clamping plate 307. The bottom of the front folding frame 301 is fixedly connected to two sliders 312. The top of the moving plate 202 and the base 1 are provided with sliding grooves 313. The sliders 312 are slidably connected inside the sliding grooves 313.

[0038] By moving the movable plate 202, the folding frame 301 can be opened. After the folding frame 301 is opened, it can drive the connecting rod 302 to rotate, thereby driving the mounting frame 303 to move upward. The mounting frame 303 can always be kept at the bottom middle of the steel pipe rotating shaft 5, thus maintaining a suitable position. Therefore, there is no need to measure various dimensions. The tension spring 306 can be connected by the limiting plate 305. The other end of the tension spring 306 is connected to the outside of the sliding rod 304, so that the tension spring 306 can play its role. The sliding rod 304 can be connected to the clamping plate 307, so that the clamping plate 307 can be installed on the two plates of the steel pipe rotating shaft 5 and can squeeze the plates to fix the steel pipe rotating shaft 5, thereby facilitating welding. The folding frame 301 can be moved by the slider 312 sliding in the sliding groove 313.

[0039] Please see the appendix Figure 8 -Appendix Figure 9 The stabilizing mechanism 4 includes two mounting strips 401 and two slots 406. A fixed cylinder 402 is fixedly connected to the front side of the mounting strip 401. A second spring 403 is fixedly connected inside the fixed cylinder 402. A sliding plate 404 is fixedly connected to the other end of the second spring 403. A round head 405 is fixedly connected to the opposite side of the sliding plate 404. The two slots 406 are fixedly connected to the left and right sides of the front mounting frame 303 respectively, and the slots 406 engage with the round heads 405.

[0040] The fixed cylinder 402 provides installation space, and the spring 403 can move the sliding plate 404 outward, and drive the round head 405 outward to engage with the slot 406, thereby connecting the two mounting frames 303 and increasing the stability of the two mounting frames 303 together.

[0041] Please see the appendix Figure 1 -Appendix Figure 3 The limiting block 206 is slidably connected to the inside of the outer column 204, and the moving groove 201 is located inside the left side of the base 1.

[0042] The limiting block 206 prevents the inner rod 203 from moving out of the inner column 204, while the moving groove 201 provides space for sliding.

[0043] Please see the appendix Figure 2 -Appendix Figure 4 A sliding rod 308 is slidably connected inside the opposite side of the mounting frame 303, and a stop plate 309 is fixedly connected to the bottom of the sliding rod 308.

[0044] The sliding rod 308 can be used to hold the rotating shaft 5 of the steel pipe against the abutment plate 309, thereby providing stability to the sliding rod 308.

[0045] Please see the appendix Figure 7 -Appendix Figure 8 A pressure spring 310 is fixedly connected to the top of the abutment plate 309. The top of the pressure spring 310 is fixedly connected to the bottom outer side of the mounting frame 303. The pressure spring 310 is located outside the sliding rod 308.

[0046] The compression spring 310 uses its own elasticity to firmly press the abutment plate 309 against the rotating shaft 5 of the steel pipe, and the sliding rod 308 provides stability, thereby increasing the stability of the mounting frame 303.

[0047] Please see the appendix Figure 7 -Appendix Figure 8 The tension spring 306 is set outside the sliding rod 304. The opposite side of the tension spring 306 is fixedly connected to the outside of the mounting frame 303. The bottom left side of the rear folding frame 301 is rotatably connected to the top rear side of the moving plate 202. The bottom right side of the rear folding frame 301 is fixedly connected to the top right side of the base 1. The top of the sliding rod 308 is fixedly connected to the round handle 311. The opposite sides of the two mounting strips 401 are fixedly connected to the left and right sides of the mounting frame 303 respectively. The sliding plate 404 is slidably connected inside the fixed cylinder 402. The top left and right sides of the steel pipe rotating shaft 5 are respectively set between the four clamping plates 307. The four corners of the steel pipe rotating shaft 5 are provided with mounting holes.

[0048] The mounting frame 303 provides a shaping base, and the round handle 311 increases the pressing area, thereby reducing the pressure and increasing the comfort of the operator. The mounting hole facilitates the installation of the steel pipe rotating shaft 5.
