Description

Technical Field

[0001] This technical solution relates to the field of motor assembly equipment technology, specifically a general-purpose tooling and capping machine. Background Technology

[0002] Existing capping machines are used for assembling the top cover and wires of water pumps or motors. By mechanizing the operation, the nuts on the wires are tightened onto the top cover, improving the assembly efficiency of the wires and top cover and the product qualification rate.

[0003] For example, Chinese patent CN202510147531.1 discloses a top cover wiring device, which uses a positioning device and a wire frame device to position the top cover and the wire respectively. The wire is then transferred to the locking device by a material transfer device. After the lifting device straightens and vertically positions the wire, the locking device tightens the nut.

[0004] However, the device still has some shortcomings: the positioning device achieves positioning by inserting the pin assembly into the fixing hole on the periphery of the top cover. However, the size of the fixing hole and the distance between the two fixing holes vary for different models of top covers. It is necessary to replace the pin assembly with a different model and adjust the installation position of the moving plate to adjust the distance between the pin assemblies to match the hole spacing. In addition, the adjustment process also requires the use of a calibration mechanism for positioning, which makes the adjustment operation cumbersome, time-consuming and labor-intensive, and the flexibility to adapt to different models of top covers is poor. Summary of the Invention

[0005] The purpose of this technical solution is to provide a universal tooling and capping machine that uses a positioning mold of a positioning mechanism to position the wire hole of the top cover.

[0036] The elastic element three is installed at the hinge of the swing rod, and the two ends of the elastic element three abut against the mounting base and the lower front end of the swing rod respectively, so as to make the rear end of the swing rod have a tendency to move away from the lower end of the lifting rod.

[0037] A connecting rod, which is installed on the front end of the swing rod, is used to drive the front end of the swing rod to swing downward.

[0038] A capping machine, comprising:

[0039] frame;

[0040] A material transfer device is installed on the frame and has several stations for placing top covers and wires. The material transfer device is used to move the top covers and wires in the stations to a set position. Each station is provided with a placement platform, and the upper end of the placement platform is provided with an anti-slip part.

The reset mechanism includes a reset drive and a reset push rod. The reset drive is slidably arranged on the second fixed frame via a slide rail slider. The reset push rod is installed on the drive end of the reset drive, and the end of the reset push rod passes through the clearance hole of the clearance mounting base and moves to abut the rear end of the connecting column. The reset mechanism is used to make the front end of the positioning mechanism have a tendency to move away from the rear end of the mounting base, so as to realize the positioning mold moving above the placement table.

[0057] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0058] 1. This technical solution establishes a positioning mechanism, which includes a sliding plate and a positioning mold detachably mounted on the front end of the sliding plate. The positioning mold directly positions the wire hole of the top cover and the nut on the wire, eliminating the need for positioning the fixing holes on the periphery of the top cover and calibrating the wire hole with a calibration mechanism, as required by existing technologies. This ensures accurate positioning of the wire hole of the top cover. Furthermore, when positioning different models of top covers, there is no need to adjust the installation position of the sliding plate. Only the positioning mold of the corresponding model at the front end of the sliding plate needs to be replaced to adapt to different specifications of top covers. This reduces the complexity of model switching, reduces the time spent changing the positioning mold, saves time and effort, and balances positioning accuracy, model adaptation flexibility, and assembly efficiency.

[0059] 2. This technical solution avoids the driving mechanism so that the positioning mold of the positioning mechanism has a tendency to retract to the mounting base. This ensures that after the positioning mold positions the top cover and the wire nut, it is no longer located on the top cover. This avoids mechanical interference between the positioning mold and the locking device, ensuring that the locking device can properly lock the nut into the wire hole. The positioning and locking processes can be connected without additional manual operation, improving the stability and continuity of the assembly process.

[0060] 3. This technical solution overcomes the force of the avoidance drive mechanism through a locking mechanism, keeping the positioning mechanism in an extended state to complete the positioning operation of the top cover and the wire nut. When the locking device performs the nut tightening operation, it triggers the unlocking component of the locking mechanism through mechanical transmission, releasing the locking component from limiting the position of the positioning mechanism. The positioning mechanism automatically avoids interference with the operation of the locking device under the drive of the avoidance drive mechanism, ensuring accurate and smooth locking action. It also eliminates the need for manual intervention in the switching process between positioning and avoidance, realizing the automated connection between positioning and locking processes, improving assembly efficiency and operational stability. At the same time, the mechanical locking method of the locking mechanism on the positioning mechanism is more reliable than manual positioning, reducing assembly defects caused by positioning deviations and improving product qualification rate.

[0061] 4. This technical solution provides an anti-slip part on the placement platform. When the top cover is placed on the anti-slip part, the anti-slip part restricts the displacement of the top cover, preventing the top cover from shifting due to force during the tightening of the nut or the movement of the material transfer device, thus ensuring the stability of the nut tightening onto the top cover and the assembly quality.

[0062] 5. This technical solution adjusts the installation position of the mounting plate on the fixed frame by adjusting the mechanism, thereby adjusting the distance between the positioning mold and the upper end of the placement platform. This achieves the adaptation and adjustment of the installation height of the universal tooling without modifying the structure of the positioning mechanism, which can meet the placement and positioning requirements of top covers of different heights and improve the adaptability and versatility of top covers of different heights.

[0063] 6. This technical solution overcomes the force of the avoidance drive mechanism through the reset mechanism, drives the positioning mechanism to extend above the placement platform, and then uses the locking mechanism to keep the positioning mechanism in the extended state so as to position the next top cover and wire to be assembled. The entire reset and locking process does not require manual operation, realizes the automated cycle of the positioning process, and further improves the continuity and efficiency of the assembly operation.

[0075] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0076] like Figure 4 and Figure 5 A general-purpose tooling, comprising:

[0077] Mounting base 31 is mounted on material transfer device 2;

[0078] The positioning mechanism 32 is slidably disposed in the mounting base 31, and the front end of the positioning mechanism 32 extends out of the front end of the mounting base 31. The front end of the positioning mechanism 32 can extend to the top of the placement platform 37. The front end of the positioning mechanism 32 extending out of the mounting base 31 is used to position the wire hole 105 of the top cover 100 and the nut 104 of the wire 101, so that the top cover 100 and the nut 104 are in the set position to facilitate the subsequent tightening operation of the locking device 6.

[0079] An avoidance drive mechanism 33 is mounted on the mounting base 31 and connected to the positioning mechanism 32. The avoidance drive mechanism 33 causes the front end of the positioning mechanism 32 to tend to retract into the mounting base 31, thus causing the positioning mechanism 32 to move towards the rear end of the mounting base 31, placing the positioning mechanism 32 in a retracted state (the retracted state is not limited to the positioning mechanism 32 being completely retracted into the mounting base 31; it is sufficient that the positioning mold 322 of the positioning mechanism 32 does not interfere with the subsequent locking operation of the locking device 6, such as disengaging the nut 104 from the positioning groove 3221). In the retracted state, interference between the positioning mechanism 32 and the subsequent locking device 6 is avoided, ensuring the stability of the locking device 6's operation; and

[0080] The locking mechanism 34 is mounted on the mounting base 31 and is movably connected to the positioning mechanism 32. The locking mechanism 34 is used to keep the positioning mechanism 32 in the extended state. In the extended state, the front end of the positioning mechanism 32 can perform positioning operations on the wire hole 105 of the top cover 100 and the nut 104 of the wire 101 on the placement platform 37.

[0081] Combination Figures 4-8 The positioning mechanism 32 includes: a sliding plate 321, which is slidably disposed within the mounting base 31, and the rear end of the sliding plate 321 is movably connected to an avoidance drive mechanism 33 and a locking mechanism 34, and the front end of the sliding plate 321 can extend out of the front end of the mounting base 31; and

[0082] The positioning mold 322 is detachably installed at the front end of the sliding plate 321 by means of screws, pins or inserts. The front end of the positioning mold 322 has a positioning groove 3221, which is used to position the wire hole 105 of the top cover 100 and the nut 104 of the wire 101. The nut 104 is positioned by placing it in the positioning groove 3221. The nut 104 is manually pre-tightened one turn or half a turn into the wire hole 105 of the top cover 100. That is, the positioning of the nut 104 indirectly ensures the accurate position of the wire hole 105 of the top cover 100. Alternatively, the wire hole 105 of the top cover 100 can be manually observed to be located in the positioning groove 3221 or in the orthographic projection of the positioning groove 3221 to the upper end of the placement platform 37 (the vertical projection of the positioning groove 3221).

[0083] The positioning mold 322 is replaced to position the top cover 100 and nut 104 of different models. The rear end structure of the positioning mold 322 of different models is the same, so that it can be adapted to the front end of the sliding plate 321 and installed. The only difference between the positioning molds 322 of different models is the size of the positioning groove 3221. When the positioning mold 322 of different models is replaced, after the positioning mold 322 of different models positions the nut 104 of their respective models, the center line of the nut 104 is located in the set position, so that the subsequent locking device 6 can drive and tighten the nut 104.

[0084] The positioning groove 3221 is a U-shaped groove, and guide surfaces 3222 are provided on both sides of the groove opening of the positioning groove 3221. The guide surfaces 3222 are used to guide the nut 104 of the wire 101 to move into the positioning groove 3221.

[0085] Combination Figures 4-8 The mounting base 31 includes a base plate 310, which is mounted on the positioning mounting plate 24 by screws;

[0086] The sliding seat 311 is mounted on the base plate 310, and a sliding through hole 3111 is provided inside the sliding seat 311, which passes through the front and rear ends of the sliding seat 311.

[0087] The anti-detachment front plate 312 is installed at the front end of the sliding seat 311 by screws, and the anti-detachment front plate 312 has a clearance opening 3121. The clearance opening 3121 is connected to the sliding through hole 3111, and the cross-sectional area of ​​the clearance opening 3121 is smaller than the cross-sectional area of ​​the sliding through hole 3111.

[0088] The anti-detachment rear plate 313 is installed at the rear end of the sliding seat 311 and is used to seal the rear end of the sliding through hole 3111.

[0089] The sliding plate 321 has an integrally formed connecting part 3211 and an anti-detachment part 3212. The front end of the connecting part 3211 extends out of the relief opening 3121 and connects to the rear end of the positioning mold 322. The connecting part 3211 can slide within the relief opening 3121. The anti-detachment part 3212 is slidably disposed within the sliding through hole 3111. The anti-detachment part 3212 moves against the edge of the relief opening 3121 to restrict the sliding plate 321 from detaching from the front end of the sliding through hole 3111. The anti-detachment rear plate 313 moves against the rear end of the anti-detachment part 3212 to restrict the sliding plate 321 from detaching from the rear end of the sliding through hole 3111.

[0090] Combination Figures 4-8 The avoidance drive mechanism 33 includes: an avoidance mounting base 331, which is mounted on the upper rear half of the mounting base 31 by screws, and the avoidance mounting base 331 is provided with an avoidance hole 3311;

[0091] The elastic element 332 is a torsion spring, tension spring, or rubber band. One end of the elastic element 332 is connected to the clearance mounting base 331 by wrapping, sleeve, screw fixing, or adhesive. The other end of the elastic element 332 is connected to the sliding plate 321 by wrapping, sleeve, screw fixing, or adhesive. The elastic element 332 is used to make the positioning mechanism 32 tend to move towards the rear end of the mounting base 31, thereby making the positioning mechanism 32 switch from the extended state to the retracted state.

[0092] The sliding plate 321 has a connecting post 3213 at its rear end, and the mounting base 31 has a strip hole 3112 at its upper end. The strip hole 3112 is connected to the sliding through hole 3111. The upper end of the connecting post 3213 extends out of the mounting base 31 through the strip hole 3112 and is connected to the elastic element 332. The connecting post 3213 can slide within the strip hole 3112.

[0093] Combination Figures 4-8 The upper end of the sliding plate 321 is provided with a locking groove 3214. The locking mechanism 34 includes a locking seat 341, which is installed on the upper end of the mounting base 31. The locking seat 341 has a mounting groove 3411 and a second clearance hole 3412. The left and right side walls of the mounting groove 3411 penetrate through the side walls of the locking seat 341, and the second clearance hole 3412 penetrates through the front side wall of the mounting groove 3411, so that the second clearance hole 3412 communicates with the interior of the mounting groove 3411. The bottom of the mounting groove 3411 and the interior of the mounting base 31 are connected through a through hole.

[0094] The locking component 35 is installed in the mounting groove 3411 of the locking base 341. The lower end of the locking component 35 passes through the bottom of the mounting groove 3411 and is inserted into the locking groove 3214 at the upper end of the sliding plate 321 of the positioning mechanism 32, so as to restrict the sliding of the sliding plate 321 in the mounting base 31.

[0095] Unlocking component 36 is mounted on mounting base 31 and is connected to locking component 35 for driving locking component 35 to move upward to release the lock on positioning mechanism 32;

[0096] The locking component 35 includes:

[0097] The locking lever 351 is vertically slidably disposed in the locking seat 341, and the lower end of the locking lever 351 extends out of the lower end of the locking seat 341 and is inserted into the locking groove 3214 at the upper end of the sliding plate 321 located in the mounting base 31.

[0098] The anti-loosening component 352 is a bolt that is threadedly connected to the upper end of the locking seat 341 and located above the locking rod 351;

[0099] The second elastic element 353, which is a spring, disc spring, or rubber pad, is installed in the locking seat 341. The upper end of the second elastic element 353 abuts against the lower end of the anti-disengagement element 352, and the lower end of the second elastic element 353 abuts against the upper end of the locking rod 351. This is used to make the locking rod 351 have a tendency to move closer to the sliding plate 321. Through the elastic deformation of the second elastic element 353, the locking rod 351 is stably inserted into the locking groove 3214 of the sliding plate 321, preventing the locking rod 351 from disengaging from the locking groove 3214 and ensuring the position of the positioning mechanism 32 is locked.

[0100] The unlocking component 36 includes: a lifting rod 361, which is horizontally inserted through the side end of the locking rod 351, and both ends of the lifting rod 361 are slidably disposed on the side end of the locking seat 341, that is, the middle part of the lifting rod 361 is connected to the locking rod 351, and the side end of the lifting rod 361 is slidably disposed in the mounting groove 3411, so that the lifting rod 361 drives the locking rod 351 to move up and down, and the lifting rod 361 moves vertically under the guidance of the mounting groove 3411;

[0101] The swing rod 362 has its middle part hinged to the anti-detachment front plate 312 of the mounting base 31 via the hinge rod 3621. The rear end of the swing rod 362 extends into the locking seat 341 through the clearance hole 3412 and moves against the lower end of the lifting rod 361. It is used to drive the lifting rod 361 to move upward, thereby driving the locking rod 351 to move upward and disengage from the locking groove 3214.

[0102] The elastic element 363, which is a torsion spring or spring, is installed at the hinge of the swing rod 362. The two ends of the elastic element 363 abut against the upper front end of the mounting base 31 and the lower front end of the swing rod 362, respectively, so that the rear end of the swing rod 362 has a tendency to move away from the lower end of the lifting rod 361, thereby enabling the lifting rod 361 and the locking rod 351 to move toward the locking groove 3214 at the upper end of the sliding plate 321.

[0103] Link 364 is mounted on the front end of swing arm 362 and is used to drive the front end of swing arm 362 to swing downward.

[0104] The lowering link 364 drives the front end of the swing arm 362 to move downward, thereby causing the rear end of the swing arm 362 to drive the lifting arm 361 to move upward. The lifting arm 361 drives the locking arm 351 to move upward and disengage from the locking groove 3214, thereby releasing the lock on the positioning mechanism 32.

[0105] When the downward pressure on the connecting rod 364 is removed, the elastic element 363 undergoes elastic deformation, causing the front end of the swing rod 362 to rise, thereby causing the rear end of the swing rod 362 to move downward, reducing the squeezing force on the elastic element 353. Under the force of the elastic element 353, the locking rod 351 moves downward, thereby enabling the locking rod 351 to be inserted into the locking groove 3214 or the lower end of the locking rod 351 to abut against the upper end of the sliding plate 321.

[0108] The transfer device 2 is mounted on the frame 1 and has several stations 21 for placing the top cover 100 and the wire 101. The turntable 22 of the transfer device 2 is used to move the top cover 100 and the wire 101 in the station 21 to a set position. The station 21 is provided with a placement platform 37. The upper end of the placement platform 37 is provided with an anti-slip part 371. The anti-slip part 371 is made of velvet, anti-slip fabric, convex strips, or convex dots. The upper end of the anti-slip part 371 is used for placing the top cover 100. The anti-slip part 371 can increase the friction between the top cover 100 and the top cover 100, thereby ensuring the stability of the top cover 100.

[0109] The general-purpose tooling 3 (i.e., positioning device) is installed on the material transfer device 2 and is used to position the top cover 100 in the station 21.

[0110] The wire frame device 4 is mounted on the material transfer device 2 and corresponds to the general-purpose tooling 3, and is used to place the wire bundle 102 of the wire 101 in the work station 21.

[0111] A lifting device, which is mounted on the frame 1 or the material transfer device 2, is used to lift the wire frame device 4 to straighten the wire portion between the wire bundle 102 and the nut 104 of the wire 101.

[0112] The locking device 6, which is installed on the frame 1, is used to tighten the nut 104 on the wire 101 in the station 21 to the top cover 100;

[0113] The unloading device 7 is mounted on the frame 1 and is located next to the transfer device 2. It is used to unload the top cover 100 of the tightening nut 104.

[0114] The present invention is provided with four general-purpose tooling 3 and four corresponding wire frame devices 4.

[0115] The material transfer device 2, wire frame device 4, lifting device, locking device 6, and unloading device 7 are all existing technologies. Their structures are based on a top cover wiring device disclosed in Chinese Patent CN202510147531.1, and will not be described in detail here.

[0116] Combination Figure 8 and Figure 9 The locking device 6 includes:

[0117] The moving mechanism 61 is mounted on the frame 1 and located beside the material transfer device 2;

[0118] A locking mechanism 62, which is mounted on a moving mechanism 61, is used to tighten the nut 104 on the wire 101 onto the top cover 100.

[0119] A pressing mechanism 63, mounted on the moving mechanism 61 and located beside the locking mechanism 62, is used to press the top cover 100 onto the placement table 37; and

[0120] Triggering mechanism 64, which is installed on the side of locking mechanism 62 or on the moving end of moving mechanism 61, is used to press down to trigger the connecting rod 364 of general-purpose tooling 3;

[0121] The pressing mechanism 65 is mounted on the frame 1 and located below the locking mechanism 62, and is used to press against the side end of the top cover 100;

[0122] The moving mechanism 61, the locking mechanism 62, and the pressing mechanism 63 are all existing technologies. The structure is based on the locking device 6 in a top cover wiring device disclosed in Chinese Patent CN202510147531.1, which will not be described in detail here. The moving end of the moving mechanism 61 refers to the buffer plate in that patent.

[0123] Combination Figure 8 and Figure 9 The triggering mechanism 64 includes:

[0124] The trigger mounting plate 641 is installed on the side of the locking mechanism 62 or on the moving end of the moving mechanism 61. The locking mechanism 62 is installed on the moving end of the moving mechanism 61. The moving mechanism 61 can drive the locking mechanism 62 to move vertically and horizontally, and the trigger mounting plate 641 can move synchronously with the movement of the locking mechanism 62.

[0125] Trigger lever 642, which is installed at the lower end of trigger mounting plate 641, is used to press down the connecting rod 364 of universal tooling 3 to release the locking assembly 35;

[0126] When the moving mechanism 61 drives the locking mechanism 62 to move above the placement platform 37, the moving mechanism 61 drives the locking mechanism 62 to move down and approach the upper end of the top cover 100 on the placement platform 37. The trigger lever 642 moves down synchronously with the locking mechanism 62, thereby causing the lower side of the front end of the trigger lever 642 to press down the connecting rod 364, causing the connecting rod 364 to drive the swing rod 362 to swing, thereby causing the locking rod 351 to move up to release the locking of the positioning mechanism 32. This causes the positioning mold 322 to move away from the wire hole portion 105 of the top cover 100 on the placement platform 37, so that the wire hole portion 105 of the top cover 100 is disengaged from the positioning groove 3221, thereby ensuring the stability of the locking mechanism 62 in screwing the nut 104 onto the wire hole portion 105.

[0127] Combination Figure 9 and Figure 10 The pressing mechanism 65 is located beside the placement table 37. The pressing mechanism 65 includes a pressing drive 651 and a pressing mold 652. The front end of the pressing mold 652 has a V-groove 653. The pressing drive 651 is a cylinder, a linear motor, or an electric push rod. The pressing drive 651 is mounted on the frame 1 and located below the moving mechanism 61 and the locking mechanism 62. The pressing drive 651 is located beside the material transfer device 2. The driving end of the pressing drive 651 is fitted with the pressing mold 652. The moving mechanism 61 drives the locking mechanism 62 to move to the top cover 100 on the placement table 37. During the upper process, the pressing drive 651 drives the pressing mold 652 to approach the side of the top cover 100 of the placement platform 37, so that the top cover 100 is placed in the V-groove 653, thereby causing the pressing mold 652 to press against the side of the top cover 100 and press the wire hole portion 105 of the top cover 100 and the nut 104 of the wire 101 against the side of the positioning groove 3221, thereby ensuring that the nut 104 is accurately positioned in the positioning groove 3221. Then the pressing mechanism 63 presses the top cover 100 tightly against the upper end of the placement platform 37, thereby achieving the positioning and restriction of the top cover 100 and the nut 104.

[0128] like Figure 2 The turntable 22 of the material transfer device 2 is equipped with a fixed frame 23 and a placement platform 37. The fixed frame 23 and the placement platform 37 rotate with the turntable 22. A positioning mounting plate 24 is slidably mounted on the fixed frame 23. A universal tooling 3 is mounted on the positioning mounting plate 24. An adjustment mechanism 25 is provided between the positioning mounting plate 24 and the fixed frame 23. The adjustment mechanism 25 is used to adjust the height position of the positioning mounting plate 24 on the fixed frame 23, thereby adjusting the distance between the universal tooling 3 and the placement platform 37, so as to adapt to the positioning and assembly of top covers 100 of different heights.

[0129] The adjusting mechanism 25 includes: adjusting wheel 251, adjusting rod 252, bevel gear set 253, and lead screw 254. Adjusting wheels 251 are installed at both ends of the adjusting rod 252. The adjusting rod 252 is mounted on the upper end of the fixed frame 23 via bearings. The middle part of the adjusting rod 252 is connected to the upper end of the lead screw 254 via the bevel gear set 253. The lead screw 254 is threadedly connected to the positioning mounting plate 24. The adjusting rod 252 is horizontally positioned, and the lead screw 254 is vertically positioned. The adjusting rod 252 and the lead screw 254 are connected by a transmission via the bevel gear set 253, which includes two meshing gears. The bevel gears are mounted on the adjusting rod 252 and the lead screw 254. By manually rotating the adjusting wheel 251, the adjusting rod 252 is rotated. The adjusting rod 252 drives the lead screw 254 to rotate through the bevel gear set 253. The lead screw 254 and the positioning mounting plate 24 are connected by a threaded engagement to drive the positioning mounting plate 24 to move vertically on the lead screw 254. The up and down movement of the positioning mounting plate 24 can drive the general-purpose tooling 3 to move up and down on the fixed frame 23, thereby adjusting the distance between the general-purpose tooling 3 and the placement table 37.

[0130] Combination Figure 2 and Figure 3 A fixed frame 26 is installed on the frame 1 or the transfer device 2. A reset mechanism 38 and a lifting device are installed on the fixed frame 26. The lifting device is located at the upper end of the fixed frame 26 and will not interfere with or touch the lower end of the lifting device due to the up-and-down movement of the positioning mounting plate 24. The center of the turntable 22 of the transfer device 2 has a clearance through hole. The lower end of the fixed frame 26 passes through the clearance through hole to connect to the frame 1 or to the outer shell or non-rotating column on the indexer at the lower end of the turntable 22, so that the fixed frame 26... 6 does not rotate with turntable 22, so that reset mechanism 38 is always in the position direction corresponding to unloading device 7, and lifting device is always in the position direction corresponding to locking device 6. After unloading device 7 unloads top cover 100 with assembled wire 101, reset mechanism 38 drives positioning mechanism 32 to extend from mounting base 31 so that positioning mold 322 of positioning mechanism 32 is placed above placement table 37, so as to position the next top cover 100 and wire 101 to be assembled.

[0131] The reset mechanism 38 includes a reset drive 381 and a reset push rod 382. The reset drive 381 is a cylinder or an electric push rod and is mounted on the fixed frame 26. The reset push rod 382 is mounted on the drive end of the reset drive 381, and the end of the reset push rod 382 passes through the clearance hole 3311 of the clearance mounting base 331 and movably abuts against the rear end of the connecting column 3213. The reset mechanism 38 is used to make the front end of the positioning mechanism 32 have a tendency to move away from the rear end of the mounting base 31, so as to realize the movement of the positioning mold 322 to the placement position. Above the platform 37; the reset push rod 382 is driven by the reset drive member 381 to pass through the clearance hole 3311 and abut against the rear end of the connecting column 3213, thereby causing the reset push rod 382 to push the connecting column 3213 to move. The connecting column 3213 drives the sliding plate 321 and the positioning mold 322 to move and move the positioning mold 322 to the upper end of the platform 37, so that the positioning mold 322 is in the extended state. Then the locking mechanism 34 locks the position of the sliding plate 321 to keep the positioning mold 322 in the extended state.

[0132] Since the general-purpose tooling 3 moves up and down on the fixed frame 23 along with the positioning mounting plate 24, the reset mechanism 38 is slidably mounted on the fixed frame 26. Specifically, the reset drive 381 is vertically slidably mounted on the fixed frame 26 via a slide rail slider. The reset mechanism 38 also includes a roller 383 and an elastic element 384. The roller 383 is rotatably mounted on the reset drive 381 and can roll on the positioning mounting plate 24. The elastic element 384 is a tension spring or rubber band, and one end of the elastic element 384 is connected to the reset drive 38 by a pin, screw, or adhesive. 1. The other end of the elastic element 384 is connected to the fixed frame 26 by means of a pin, screw or adhesive. The elastic element 384 causes the reset drive 381 to have a tendency to move closer to the turntable 22. The elastic element 384 pulls the reset drive 381 downward so that the roller 383 keeps in contact with the upper end of the positioning mounting plate 24, thereby ensuring that the position of the reset drive 381 and the reset push rod 382 on the positioning mounting plate 24 corresponds to the general tooling 3, thereby ensuring that the end of the reset push rod 382 can pass through the clearance hole 3311 and abut against the rear end of the connecting column 3213.
