Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bicycle frame, in particular to a stable welding device applied to light bicycle frame processing. BACKGROUND

[0002] Light bicycle frame takes "realizing extreme weight reduction on the premise of ensuring the required strength and rigidity for riding" as the core goal, and the mainstream materials cover aluminum alloy with outstanding cost performance, easy processing and balanced lightweight effect, high-end carbon fiber with better lightweight performance and certain shock absorption, and titanium alloy with lightweight and durability but higher cost, in addition to the lightweight improved version of high-strength steel (taking into account toughness and basic weight reduction needs). The core short board in the current light bicycle frame welding field is difficult to simultaneously adapt to precise processing and batch production needs. In the pre-position adjustment, either the labor intensity is large and the precision relies on experience, or there is no stable limiting after simple electric adjustment, the parts are easy to deviate during transfer or clamping, which directly affects the welding precision. In multi-station operation, the traditional single-station equipment needs to complete the whole process of a group of processing to start the next group, which is low in efficiency. A few multi-station equipment also lack unified positioning reference and linkage design, and the parts need to be re-calibrated after transfer, which cannot realize seamless alternation of "pre-installation-welding-transfer", and it is also difficult to adjust parameters and layout according to frame specifications, which is time-consuming for replacement, and the independent pre-adjustment of each component is easy to cause misalignment, and the misalignment of parts caused by poor connection during transfer makes it difficult to balance the pre-adjustment accuracy, multi-station efficiency and processing stability.

[0003] Therefore, there is an urgent need to develop a technical solution that can realize accurate pre-adjustment of each component, multi-station collaborative linkage and adaptation to multi-specification frames, and seamless operation. SUMMARY

[0009] Further, the bottom of the inclined sliding seat is rotatably connected with a rotating seat, and the bottom of the inclined sliding seat is also fixedly installed with a micro electric push cylinder, the top of the rotating seat is fixedly installed with a sliding rail on one side, and the output end of the micro electric push cylinder is fixedly connected with a sliding block for sliding in the sliding rail; The top of the smooth seat and the bottom of the rotating seat are respectively fixedly installed with a first electric clamping part and a second electric clamping part for clamping or releasing the upper pipe and the vertical pipe.

[0010] Further, the top of the bottom plate is fixedly connected with two vertical plates, the bottom of the rack is fixedly connected with the top of the two vertical plates, and the side wall of one of the vertical plates is installed with a horizontal electric push rod and an inclined electric push rod, and the output end of the horizontal electric push rod and the inclined electric push rod is fixedly connected with a positioning plate; The side clamping mechanism comprises a sleeve, and the side wall of the other vertical plate is fixedly connected with the sleeve.

[0011] Further, the sleeve is slidingly connected with a sliding rod, the inside of the sleeve is fixedly installed with a first electric push rod for driving the sliding rod to slide, one end of the sliding rod located outside the sleeve is fixedly connected with a connecting plate, and the side wall of the connecting plate is fixedly installed with a third electric clamping part for clamping or releasing the vertical pipe; The side wall of the vertical plate below the sleeve is fixedly connected with a support plate, the top of the support plate is fixedly installed with a second lifting push cylinder, and the top end of the second lifting push cylinder is fixedly connected with a centering plate.

[0012] Further, the ground radial support component can extend into the head tube 400 and expand radially to support the tube wall, and the ground radial support component is an inner circle expansion support mechanism.

[0013] Further, the ground clamping mechanism comprises a material supporting box, both ends of the material supporting box are slidably connected with a pair of clamping plates, both ends of the inside of the material supporting box are fixedly installed with second electric push rods, and the output ends of the second electric push rods are fixedly connected with the pair of clamping plates.

[0014] Further, the top of the bottom plate is fixedly installed with two track frames, the inside of the track frame is slidably connected with an electric sliding table, the top of the electric sliding table is fixedly connected with a vertical sliding frame, the inside of the vertical sliding frame is slidably connected with a limiting block, the outer side of the limiting block is fixedly installed with an electric lifting frame, and the top end of the electric lifting frame is fixedly connected with the corresponding inner circle expansion support mechanism and the bottom of the material supporting box.

[0015] Compared with the prior art, the beneficial effects of the present application are: 1、The present application takes "full-precision positioning of parts + multi-node rigid limiting" as the core to ensure the precision stability of the butt joint and welding of each part. In the positioning link, the horizontal electric push rod and the inclined electric push rod provide the standardized reference of the upper pipe and the lower pipe through the alignment plate, and cooperate with the threaded rod driven by the motor outside the machine box to realize the linear fine adjustment of the smooth seat and the inclined slide seat, so as to guarantee the angle and length butt joint precision of the upper pipe and the lower pipe. The inner circle expansion support mechanism is adopted for the head pipe, and the center precision positioning is realized by relying on the pipe wall fitting, so as to ensure the coaxiality of the butt joint of the head pipe, the upper pipe and the lower pipe. For the vertical pipe, the bottom end is pre-centered by driving the centering plate to rise through the second lifting push cylinder, and then the sleeve and the slide rod of the side clamping mechanism cooperate with the first electric push rod to adjust the position, so that the third electric clamping piece accurately clamps the vertical pipe, and the butt joint precision of the vertical pipe and the upper pipe and the middle shaft bowl group is guaranteed. For the middle shaft bowl group, the second electric push rod in the box drives the clamping plate to clamp from both ends to avoid horizontal displacement of the middle shaft bowl group, so as to ensure the butt joint fitting degree of the middle shaft bowl group and the lower pipe and the bottom end of the vertical pipe, and finally realize the significant reduction of the butt joint gap of each part, so that the geometric deviation of the welded frame is controllable without additional correction process.

[0016] 2、The application takes "parallel operation + automatic adjustment" as the core to build a non-waiting processing flow. On the one hand, the two groups of multidirectional clamping mechanisms under the rotating support frame form a double-station parallel mode: when one group completes the fixation and welding cooperation of the upper pipe and the lower pipe in the welding station, the other group can simultaneously complete the clamping and alignment plate calibration of a new group of upper pipe and lower pipe in the pre-installation station. After welding is completed, the rotating support frame only needs to rotate through the annular track to realize seamless switching of finished product transfer and workpiece in position, saving the time of single-station waiting installation and greatly compressing the single-batch processing cycle. On the other hand, the position adjustment of the upper pipe / lower pipe (the height and horizontal adjustment of the head pipe / central shaft bowl group, and the clamping and movement of the vertical pipe are all automatically completed), not only avoids the error of manual positioning (such as angle deviation and uneven alignment gap), but also reduces the labor intensity of manual operation, adapts to the high consistency and fast-paced processing demand in large-scale production, and realizes continuous cycle operation.

[0027] It can be known from the embodiments one, two, three and four that the core target of the device is to realize precise positioning, assembling and welding of the bicycle frame main body (upper pipe 100, vertical pipe 200, lower pipe 300, head pipe 400, middle shaft bowl group 500) through the cooperation of multiple mechanisms, and the overall process is divided into three stages of early part fixing and position pre-adjustment, multiple part cooperative assembling alignment and welding execution, and the specific operation logic is as follows: (1) Stage one: early part fixing and position pre-adjustment This stage needs to complete the preliminary fixing of each frame part, and realizes position pre-calibration through a special mechanism to lay a foundation for subsequent assembly, and the processing mode of each part is as follows: Pre-fixing and position adjustment of the upper pipe 100 and the lower pipe 300 (multi-directional clamping mechanism dominant) First, start two groups of multi-directional clamping mechanisms, place the upper pipe 100 in the first electric clamping piece 306 on the top of the smooth seat 302, and place the lower pipe 300 in the second electric clamping piece 307 at the bottom of the rotating seat 304, and the first electric clamping piece 306 and the second electric clamping piece 307 (existing clamping mechanism) are started synchronously to respectively clamp and fix the upper pipe 100 and the lower pipe 300 to avoid displacement during subsequent adjustment.

[0028] Pre-adjustment reference: The horizontal electric push rod 701 and the inclined electric push rod 702 of the vertical plate side wall are pre-adjusted, the alignment plates at the output ends of the two are pushed to the preset fixed position (this position is the standard alignment reference of the upper pipe 100 and the lower pipe 300); at the same time, the micro electric push cylinder 305 at the bottom of the inclined sliding seat 303 is started, the rotating seat 304 is driven to deflect by pushing the sliding block in the sliding rail, and after the lower pipe 300 is adjusted to the preset inclination angle, the micro electric push cylinder 305 remains fixed to ensure the stability of the angle of the lower pipe 300.

[0029] Accurate position calibration: start the motor outside the case 301 (corresponding to the smooth groove, inclined groove inside the threaded rod), the motor drives the threaded rod to rotate, and then drives the smooth seat 302 to slide along the smooth groove, and the inclined slide 303 slides along the inclined groove; until one end of the upper pipe 100 contacts the alignment plate of the horizontal electric push rod 701, and one end of the lower pipe 300 contacts the alignment plate of the inclined electric push rod 702, at this time the position adjustment of the upper pipe 100 and the lower pipe 300 is completed; then control the horizontal electric push rod 701 and the inclined electric push rod 702 to retract the alignment plate to avoid interfering with the subsequent rotation.

[0030] Fixing of head pipe 400 (ground radial support component / inner circle expansion support mechanism 8 dominant) The head pipe 400 is sleeved on the outside of the inner circle expansion support mechanism 8, the inner circle expansion support mechanism 8 (existing radial support mechanism) extends into the pipe inside the head pipe 400 after starting, and expands radially, tightly fits the inner wall of the head pipe 400, and realizes the support and fixation of the pipe wall; at the same time, the electric sliding table in the track frame 11 on the top of the bottom plate 2 and the limiting block in the vertical sliding frame 12 do not act, the inner circle expansion support mechanism 8 is kept at the initial height by the electric lifting frame 13, and waits for subsequent assembly.

[0031] Fixing of vertical pipe 200 (side edge clamping mechanism dominant) First, start the second lifting push cylinder 14 (installed on the top of the support plate below the vertical plate), push the centering plate 15 to rise to a predetermined height, place the bottom end of the vertical pipe 200 on the top of the centering plate 15, and realize the preliminary centering of the vertical pipe 200; then start the first electric push rod of the side edge clamping mechanism (installed inside the sleeve 901), push the sliding rod 902 to slide along the sleeve 901, drive the adapter plate and the third electric clamping piece 903 (existing clamping mechanism) to approach the vertical pipe 200, and the third electric clamping piece 903 realizes clamping and fixing of the outside of the vertical pipe 200 after starting; finally, control the second lifting push cylinder 14 to drive the centering plate 15 to descend, so as to avoid interfering with the subsequent assembly movement of the vertical pipe 200.

[0032] Fixing of middle shaft bowl group 500 (ground clamping mechanism dominant) Place the middle shaft bowl group 500 in the groove on the top of the material supporting box 101 (the groove is used for preliminary positioning), start the second electric push rod at both ends inside the material supporting box 101, push the two end clamping plates 102 to slide along the material supporting box 101, until the two end clamping plates 102 tightly fit the two ends of the middle shaft bowl group 500, realize clamping and fixing of the middle shaft bowl group 500; at this time, the material supporting box 101 is kept at the initial height by the electric lifting frame 13, and waits for subsequent assembly.

[0033] (2) Stage two: multi-part cooperative assembly alignment After the pre-fixing, the upper tube 100, the lower tube 300, the head tube 400, the vertical tube 200, and the middle shaft bowl group 500 are adjusted to the accurate position required for welding, and complete assembly is achieved: Alignment of the upper tube 100, the lower tube 300, and the head tube 400: The motor at the top of the rack 1 is started to drive the rotating support frame 5 to rotate along the inner wall of the annular track 4 (the annular track 4 is fixed to the bottom of the rack 1), and to drive the group of multi-directional clamping mechanisms responsible for welding and fixing to move, so that the clamped upper tube 100 and lower tube 300 are close to the head tube 400. When the rotating support frame 5 rotates to the specified angle, the electric push rod on one side of the top of the rack 1 is started to extend and abut against the rotating support frame 5, achieving limiting and fixing, avoiding the rotating support frame 5 from being deflected by external interference, and ensuring the accuracy of subsequent alignment.

[0034] Subsequently, the electric lifting frame 13 corresponding to the head tube 400 (connected to the bottom of the inner circle expansion support mechanism 8) is started, and the inner circle expansion support mechanism 8 is lifted by the limiting block in the vertical sliding frame 12 to push the head tube 400 to the preset height. At the same time, the electric sliding table in the track frame 11 is started to drive the vertical sliding frame 12 and the inner circle expansion support mechanism 8 to move horizontally until the side wall of the head tube 400 is in close contact with the corresponding end of the upper tube 100 and the lower tube 300, completing the alignment of the three.

[0035] Alignment of the vertical tube 200 and the upper tube 100: The first electric push rod of the side clamping mechanism is started to push the sliding rod 902 along the sleeve 901 again, driving the third electric clamping piece 903 to move the clamped vertical tube 200 towards the upper tube 100 until the side wall of the vertical tube 200 is in close contact with the other end of the upper tube 100, completing the alignment of the vertical tube 200 and the upper tube 100.

[0036] Alignment of the middle shaft bowl group 500 and the lower tube 300 and the vertical tube 200: The electric lifting frame 13 corresponding to the middle shaft bowl group 500 (connected to the bottom of the material holding box 101) is started, and the material holding box 101 is lifted by the limiting block in the vertical sliding frame 12 to push the middle shaft bowl group 500 to the preset height. Until the outer wall of the middle shaft bowl group 500 is in close contact with the bottom end of the lower tube 300 and the bottom end of the vertical tube 200, completing the alignment of the middle shaft bowl group 500 and the lower tube 300 and the vertical tube 200.

[0037] At this point, the upper tube 100, the vertical tube 200, the lower tube 300, the head tube 400, and the middle shaft bowl group 500 have all been accurately assembled in place, meeting the position requirements for welding.

[0038] (Three) Stage three: welding execution: Under the condition that each part remains accurately assembled, the external welding equipment is started, and the welding is performed according to the welding sequence and the welding parameters required by the welding process. Figure 9The welding positions shown are the welding positions of the connecting parts of the upper tube 100 and the head tube 400, the upper tube 100 and the vertical tube 200, the lower tube 300 and the head tube 400, the lower tube 300 and the middle shaft bowl group 500, and the vertical tube 200 and the middle shaft bowl group 500; during the welding process, each clamping mechanism, supporting mechanism and limiting mechanism keeps working to ensure that the parts have no displacement and the welding precision is ensured.

[0039] After the welding is completed, each clamping mechanism releases the parts, the electric push rod is retracted, the support frame 5 is rotated to drive the "welded frame body" to the transfer position, and the other group of "pre-installed non-welded parts" is rotated to the welding position, so that the alternation of the welded frame body and the non-welded frame body is realized, and the next round of welding cycle is entered.
