Description

Technical Field

[0001] The invention relates to the technical field of hardware installation, in particular to a quick embedding fixture for installing hardware gaskets. Background Art

[0002] A gasket is a mechanical seal between two objects, usually used to prevent leakage from pressure, corrosion and the natural expansion and contraction of pipes. A gasket is a loophole in a thin plate and is usually a load thread fastener used to distribute.

[0003] In the process of processing and assembling some workpieces, it is necessary to place the hardware gasket in the corresponding position. The traditional assembly method generally adopts manual picking and then installs it on the product. However, the manual picking installation is not convenient for picking up due to the small size and thinness of the gasket, which causes a slow picking process and wastes manpower. In order to hold the gasket well during the manual picking process, the staff will pinch it hard. Once the force is too large, it will cause problems such as gasket bending and damage, affecting the assembly efficiency. And because the installation slot corresponding to the hardware gasket on the product is also small, it is easy to cause inaccurate installation when the hardware gasket is installed manually, and the staff will be fatigued after long-term work, resulting in a higher error rate, thereby greatly reducing the work efficiency. Although there is a mechanized automatic clamping installation in the prior art, it is difficult to firmly clamp the hardware gasket during the clamping process due to the light weight and small size of the hardware gasket, and the hardware gasket cannot be accurately embedded in the product without a positioning mechanism, which affects the later assembly and is not conducive to actual use.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 8 The present invention provides a technical solution: a quick embedding jig for installing hardware gaskets, comprising a gasket conveyor belt 1 and a die base conveyor belt 11, the gasket conveyor belt 1 and the die base conveyor belt 11 are adjacently distributed, and a spacing is left between the gasket conveyor belt 1 and the die base conveyor belt 11, the gasket conveyor belt 1 and the die base conveyor belt 11 are both installed in a support seat, a horizontal plate 12 is installed above between the gasket conveyor belt 1 and the die base conveyor belt 11, a plurality of partition plates are fixedly connected to the gasket conveyor belt 1 and the die base conveyor belt 11 at equal intervals, the gasket conveyor belt 1 is used to transmit the hardware gasket body 44, and the die base conveyor belt 11 is used to transmit the lower die base 8; The lower end of the horizontal plate 12 is rotatably in contact with a lifting platform 13, and a hydraulic cylinder 15 is fixedly installed at the lower end of the lifting platform 13. The hydraulic cylinder 15 can be directly fixed on the ground, or directly installed on the side of the gasket conveyor belt 1 and the mold base conveyor belt 11. The horizontal plate 12 is driven by the motor shaft of a self-locking stepper motor fixedly installed at the lower end of the lifting platform 13. The upper end of the motor shaft penetrates the lifting platform 13 from bottom to top and is fixedly connected to the horizontal plate 12. The motor shaft is rotatably connected to the lifting platform 13. The left and right ends of the horizontal plate 12 are symmetrically fixed with bearing seats 2. The upper ends of the two bearing seats 2 are penetrated from top to bottom with rectangular grooves. An adsorption mechanism for picking up the hardware gasket body 44 is installed in the rectangular groove. Auxiliary clamping mechanisms are symmetrically installed in the rectangular groove, and a driving mechanism is installed above the inner side of the rectangular groove.

[0022] The gasket conveyor belt 1 and the die base conveyor belt 11 are both equipped with a clamping and positioning mechanism, which is used to position the metal gasket body 44 and the lower die base 8 so that they are in the middle position between the two partition plates on the conveyor belt, which is convenient for later operations; The clamping and positioning mechanism is composed of a clamping cylinder and a clamping plate. The two clamping cylinders are extended and retracted at the same time to drive the clamping plate to move. The two clamping plates cooperate to position the hardware gasket body 44 and the lower die seat 8. The clamping and positioning mechanism can also be composed of other components as long as they can meet the requirements of positioning the hardware gasket body 44 and the lower die seat 8. The gasket conveyor belt 1 and the mold base conveyor belt 11 are both step-by-step transmissions. Each time the gasket conveyor belt 1 and the mold base conveyor belt 11 move one unit, the hardware gasket body 44 and the lower mold base 8 move one unit, so that the hardware gasket body 44 and the lower mold base 8 are accurately moved to the bottom of the two supporting seats 2, and so on and so forth, so that the hardware gasket body 44 and the lower mold base 8 are moved to the bottom of the supporting seat 2 in turn, and then the operation is carried out.

[0024] The motor shaft of the self-locking stepper motor rotates half a circle each time, and the motor shaft of the self-locking stepper motor first rotates half a circle forward and then rotates half a circle reversely, and repeats this process alternately. When the motor shaft rotates, it drives the transverse plate 12 to rotate one hundred and eighty degrees, and the transverse plate 12 drives the annular plate 16 to rotate along the annular groove 14, so that the transverse plate 12 can rotate stably. When the transverse plate 12 rotates, it drives the two bearing seats 2 to rotate, so that the positions of the two bearing seats 2 are interchanged, and this reciprocating movement can be used to simultaneously pick up and assemble the hardware gasket body 44, thereby greatly improving work efficiency.

[0025] The hydraulic cylinder 15 is extended and retracted to drive the lifting platform 13 to move up and down, and the lifting platform 13 drives the two bearing seats 2 to move up and down through the cross plate 12. When the hardware gasket body 44 needs to be picked up and assembled, the hydraulic cylinder 15 is retracted to make the cross plate 12 drive the two bearing seats 2 to move downward. When the hardware gasket body 44 needs to be transferred, the inner rod of the hydraulic cylinder 15 needs to be extended upward first, so that the cross plate 12 drives the two bearing seats 2 to move upward. The heights of the gasket conveyor belt 1 and the mold base conveyor belt 11 are set according to actual conditions to ensure that when the driving mechanisms in the two bearing seats 2 drive the adsorption mechanisms to move downward, the hardware gasket bodies 44 can be picked up and assembled at the same time.

The upper end of the annular connecting seat 4 is in an annular array and is penetrated and inserted with an air guide tube 43 from top to bottom. The lower end of the air guide tube 43 extends downward into the fan-shaped groove 41, and the lower end of the air guide tube 43 is penetrated and inserted in the upper end of the suction cup 42. The upper end of the air guide tube 43 penetrates the lower end of the air cylinder 3 and extends to its inner cavity. The suction cup 42 is in extrusion contact with the upper end of the hardware gasket body 44, and the two auxiliary clamping mechanisms are symmetrically distributed on both sides of the lower end of the adsorption mechanism.

[0027] The air guide tube 43 is fixedly connected to the annular connecting seat 4, the upper end of the air guide tube 43 is connected to the inner cavity of the air cylinder 3, and the lower end of the air guide tube 43 is connected to the inner cavity of the suction cup 42. The annular connecting seat 4 is made of rubber material.

[0028] The cylindrical surface of the air cylinder 3 is symmetrically fixedly connected with a convex slider 35 in the front and rear directions, and a return spring 36 is fixedly installed at the lower end of the convex slider 35. The convex slider 35 is slidably connected to the slide groove 21 up and down, and the lower end of the return spring 36 abuts against the lower end of the slide groove 21.

[0029] When the air cylinder 3 moves up and down, it drives the convex slider 35 to slide up and down along the slide groove 21 , so that the air cylinder 3 can move up and down stably, and the return spring 36 applies elastic force to the convex slider 35 .

[0030] See also Figures 2 to 4 , Figures 6 to 8The auxiliary clamping mechanism includes a rotating plate 7 installed in a rectangular groove of the supporting seat 2, the lower end of the rotating plate 7 is fixedly connected with an L-shaped clamping claw 71, the upper end of the rotating plate 7 is symmetrically fixedly connected with a rotating shaft 72, and gears 73 are fixedly sleeved on the two rotating shafts 72. The rotating plate 7 is rotatably connected to the supporting seat 2 through the rotating shaft 72. The lower ends of the left and right sides of the supporting seat 2 are symmetrically provided with through grooves 22. When the rotating plate 7 rotates upward, it rotates into the through grooves 22. The driving mechanism is arranged above the auxiliary clamping mechanism. The through grooves 22 are arranged to prevent the rotating plate 7 from colliding with the supporting seat 2 during rotation, so that the rotating plate 7 can rotate stably.

[0031] The L-shaped clamping claw 71 is an L-shaped block with an arc groove on the inner side, and the curvature of the arc groove matches the outer diameter of the hardware gasket body 44. The two L-shaped clamping claws 71 are symmetrically distributed on both sides of the lower end of the annular connecting seat 4, and the two L-shaped clamping claws 71 are symmetrically clamped on the left and right sides of the hardware gasket body 44.

[0032] The hardware gasket body 44 is clamped and fixed by the cooperation of two L-shaped clamping claws 71. At this time, the side surfaces of the L-shaped clamping claws 71 are tightly attached to the side surfaces of the hardware gasket body 44 and the annular connecting seat 4. At the same time, the lower end of the inner side of the L-shaped clamping claws 71 contacts the lower end of the hardware gasket body 44, thereby clamping and positioning the hardware gasket body 44 to prevent the hardware gasket body 44 from shaking or falling off during transportation and movement, thereby ensuring the stable transportation of the hardware gasket body 44 and ensuring that the subsequent hardware gasket body 44 can be accurately assembled.

[0033] See also Figures 2 to 4 The driving mechanism includes a lifting frame 5 in a rectangular groove of the bearing seat 2 which is slidably installed up and down. The upper end of the lifting frame 5 is fixedly connected to the lower end of the movable inner rod of the lifting cylinder 51. The lifting cylinder 51 is fixedly installed on the upper end of the bearing seat 2. The movable inner rod of the lifting cylinder 51 extends downward into the rectangular groove. The lower end of the lifting frame 5 is symmetrically fixedly connected with a lower pressing plate 52. The lower pressing plate 52 is arranged above the convex slider 35, and there is a certain distance between the lower pressing plate 52 and the convex slider 35. The lower end of the lifting frame 5 is symmetrically fixedly connected with multiple outer sleeves 6, the upper end of the outer sleeve 6 is open, and the lower end of the inner cavity of each outer sleeve 6 is slidably connected with a telescopic inner rod 61, and the lower end of each telescopic inner rod 61 passes downward through the lower end of the outer sleeve 6 and extends to the outside and is fixedly connected to the tooth plate 63. The inner cavity of the outer sleeve 6 is installed with a thrust spring 62, and the side surface of each tooth plate 63 is meshed with a nearby gear 73. The rectangular groove of the bearing seat 2 is symmetrically fixedly connected with a limit baffle 23, and the limit baffle 23 is arranged below the tooth plate 63.

[0034] When the tooth plate 63 moves downward for a certain distance, it will abut against the limit baffle 23, and the limit baffle 23 will abut against the tooth plate 63, so that the tooth plate 63 cannot move further downward. Before the tooth plate 63 contacts the limit baffle 23, the lower pressure plate 52 will not contact the convex slider 35.

[0035] The telescopic inner rod 61 is composed of the upper end of a round rod and a round block fixedly connected or integrally formed. The round block at the upper end of the telescopic inner rod 61 is slidably connected to the inner wall of the outer sleeve 6 up and down, and the upper and lower ends of the thrust spring 62 are respectively in contact with the lifting frame 5 and the telescopic inner rod 61.

[0036] The lifting frame 5 is driven to move up and down by the telescopic inner rod of the lifting cylinder 51, and the lifting frame 5 drives the telescopic inner rod 61 and the tooth plate 63 to move up and down through the outer sleeve 6; When the movable inner rod of the lifting cylinder 51 extends downward, it drives the lifting frame 5 to slide downward along the rectangular groove, and the lifting frame 5 drives the outer sleeve 6 and the lower pressure plate 52 to move downward. The outer sleeve 6 drives the tooth plate 63 to move downward through the telescopic inner rod 61. During the downward movement of the tooth plate 63, the gear 73 is driven to rotate. The gear 73 drives the rotating plate 7 to rotate through the rotating shaft 72, so that the lower end of the rotating plate 7 is away from the annular connecting seat 4 and rotates; When the rotating plate 7 rotates, the L-shaped clamping claw 71 is driven to rotate, so that the rotating plate 7 and the L-shaped clamping claw 71 rotate into the through groove 22, so that the L-shaped clamping claw 71 moves away from the lower end of the annular connecting seat 4 until the lower end of the tooth plate 63 abuts against the limit stopper 23, at which time the tooth plate 63 stops moving downward, that is, the gear 73, the rotating plate 7, and the L-shaped clamping claw 71 stop rotating; At this time, the movable inner rod of the lifting cylinder 51 pushes the lifting frame 5 to continue to move downward, and the lifting frame 5 drives the lower pressure plate 52 and the outer sleeve 6 to continue to move downward, and the lower end of the outer sleeve 6 slides downward along the telescopic inner rod 61. At the same time, because the tooth plate 63 cannot continue to move downward, the telescopic inner rod 61 cannot move downward. When the lifting frame 5 moves upward, it cooperates with the telescopic inner rod 61 to squeeze the thrust spring 62. At this time, the lower end of the lower pressure plate 52 contacts the upper end of the convex sliding block 35. In the process of the lower pressure plate 52 continuing to move downward, the lower pressure plate 52 pushes the convex sliding block 35 to move downward along the slide groove 21, so that the adsorption mechanism moves downward as a whole; The annular connecting seat 4 in the adsorption mechanism is extended downward along the rectangular groove. When loading, the lower end of the annular connecting seat 4 abuts against the upper end of the hardware gasket body 44, and the suction cup 42 is buckled on the upper end of the hardware gasket body 44; Then, the piston rod 32 is driven upward by the push-pull cylinder 34, and the piston rod 32 drives the piston seat 33 to move upward, and the gas in the air guide pipe 43 and the suction cup 42 is drawn upward through the piston seat 33, so that the suction cup 42 firmly adsorbs the hardware gasket body 44; When assembling, the annular connecting seat 4 drives the hardware gasket body 44 to be inserted into the product cavity, so that the hardware gasket body 44 is accurately embedded in the product, and then the piston rod 32 is driven downward by the push-pull cylinder 34, and the piston rod 32 drives the piston seat 33 to move downward, and the gas in the gas cylinder 3 is pushed downward along the air guide pipe 43, so that the suction cup 42 releases the adsorption of the hardware gasket body 44, and the annular connecting seat 4 is separated from the hardware gasket body 44.

[0037] Then, the movable inner rod of the lifting cylinder 51 contracts to move the driving mechanism upward. At this time, the lifting frame 5 drives the lower pressing plate 52 and the outer sleeve 6 to move upward first. During the upward movement of the lower pressing plate 52, the convex slider 35 is pushed upward by the elastic force of the reset spring 36, so that the adsorption mechanism moves upward to reset. During this process, the thrust spring 62 is always in a compressed state, and the tooth plate 63 is kept stationary under the action of the elastic force of the thrust spring 62, that is, the lower end of the tooth plate 63 is continuously in contact with the upper end of the limit baffle 23; When the upper end of the lower pressing plate 52 is separated from the convex slider 35, the adsorption mechanism completes the reset. If the lower end of the adsorption mechanism adsorbs the hardware gasket body 44, the adsorption mechanism drives the hardware gasket body 44 to move upward into the rectangular groove. At this time, the lifting frame 5 drives the lower pressure plate 52 and the outer sleeve 6 to continue to move upward, and drives the telescopic inner rod 61 to move upward through the outer sleeve 6, and the telescopic inner rod 61 drives the toothed plate 63 to move upward, and the toothed plate 63 drives the gear 73 to rotate back, and the gear 73 drives the rotating plate 7 and the L-shaped clamping claw 71 to rotate downward through the rotating shaft 72 for reset, so that the L-shaped clamping claw 71 is stuck in the lower end of the annular connecting seat 4. If the lower end of the annular connecting seat 4 is adsorbed with a hardware gasket body 44 at this time, the L-shaped clamping claw 71 is stuck in the side of the hardware gasket body 44, and the hardware gasket body 44 is further clamped and fixed by the two L-shaped clamping claws 71 to prevent the hardware gasket body 44 from deflecting or falling.

[0038] See also Figure 2 and Figure 5 The upper end of the lower mold base 8 is symmetrically fixed with multiple positioning rods 81, and a product body 82 is installed in the model of the lower mold base 8. The upper end of the product body 82 is provided with a cavity for installing the hardware gasket body 44, and the lower end of the bearing seat 2 is symmetrically provided with positioning holes 24 matching the positioning rods 81, and the positioning rods 81 are plugged into the positioning holes 24.

[0039] When the bearing seat 2 is above the lower mold seat 8, if the bearing seat 2 moves downward at this time, the positioning hole 24 at the lower end of the bearing seat 2 slowly fits on the positioning rod 81, so that the bearing seat 2 and the lower mold seat 8 are aligned up and down, ensuring that the subsequent hardware gasket body 44 can be accurately embedded in the cavity of the product body 82, ensuring the accuracy of assembly.

[0040] Working principle: When working, the gasket conveyor belt 1 and the die base conveyor belt 11 rotate synchronously, so that the metal gasket body 44 and the lower die base 8 are simultaneously conveyed to the bottom of the two bearing seats 2. During the conveying process, the metal gasket body 44 and the lower die base 8 are positioned respectively by the clamping and positioning mechanisms provided on the gasket conveyor belt 1 and the die base conveyor belt 11, so that the metal gasket body 44 and the lower die base 8 are both in the middle position between the two partition plates on the conveyor belt; The lifting platform 13 and the horizontal plate 12 are driven downward by the contraction of the inner rod of the hydraulic cylinder 15, and the horizontal plate 12 drives the two bearing seats 2 to move downward synchronously. At this time, the positioning hole 24 at the lower end of the bearing seat 2 above the lower die seat 8 is slowly sleeved on the positioning plug rod 81, so that the bearing seat 2 and the lower die seat 8 are aligned up and down to ensure that the subsequent hardware gasket body 44 can be accurately embedded in the cavity of the product body 82 to ensure the accuracy of assembly. Then, the driving mechanisms in the two bearing seats 2 push the two auxiliary clamping mechanisms to open, so that the L-shaped clamping claws 71 are away from the annular connecting seat 4, and then the adsorption mechanism is pushed downward by the driving mechanism; At this time, after the adsorption mechanism above the hardware gasket body 44 moves downward, the lower end of the annular connecting seat 4 in the adsorption mechanism abuts against the upper end of the hardware gasket body 44, and the suction cup 42 is buckled on the upper end of the hardware gasket body 44; Then, the piston rod 32 is driven upward by the push-pull cylinder 34, and the piston rod 32 drives the piston seat 33 to move upward, and the gas in the air guide pipe 43 and the suction cup 42 is drawn upward through the piston seat 33, so that the suction cup 42 firmly adsorbs the hardware gasket body 44; After the adsorption mechanism adsorbs and fixes the hardware gasket body 44, the driving mechanism moves upward. At this time, the adsorption mechanism moves upward under the action of the elastic force of the reset spring 36, and the adsorption mechanism drives the hardware gasket body 44 to move upward into the rectangular groove of the supporting seat 2. When the lower pressure plate 52 in the driving mechanism is separated from the convex slider 35 in the adsorption mechanism, the driving mechanism continues to move upward. At this time, the driving mechanism drives the two auxiliary clamping mechanisms to merge, so that the L-shaped clamping claws 71 in the two auxiliary clamping mechanisms are stuck on the left and right sides of the hardware gasket body 44, thereby further clamping and fixing the hardware gasket body 44 to prevent the hardware gasket body 44 from being offset or falling off during the transfer process.

[0041] At the same time, after the adsorption mechanism above the lower die seat 8 moves downward, the annular connection seat 4 in the adsorption mechanism drives the hardware gasket body 44 to be inserted into the cavity at the upper end of the product body 82, and then the piston rod 32 is driven downward by the push-pull cylinder 34, and the piston rod 32 drives the piston seat 33 to move downward, and the gas in the gas cylinder 3 is pushed downward along the air guide pipe 43, so that the suction cup 42 releases the adsorption of the hardware gasket body 44, and the annular connection seat 4 is separated from the hardware gasket body 44; At this time, the driving mechanism moves upward, and under the action of the elastic force of the reset spring 36, the adsorption mechanism moves upward for reset. The driving mechanism continues to move upward and then drives the two auxiliary clamping mechanisms to merge and reset, so that the L-shaped clamping claws 71 in the two auxiliary clamping mechanisms are stuck at the lower end of the annular connecting seat 4.

[0042] At this time, the inner rod of the hydraulic cylinder 15 extends upward to drive the lifting platform 13 and the horizontal plate 12 to move upward, and the horizontal plate 12 drives the two bearing seats 2 to move upward synchronously. At this time, the motor shaft of the self-locking stepper motor rotates half a circle, and the motor shaft drives the horizontal plate 12 to rotate 180 degrees, and the horizontal plate 12 drives the two bearing seats 2 to rotate, so that the positions of the two bearing seats 2 are interchanged; At this time, the supporting seat 2 after the hardware gasket main body 44 is assembled is rotated to the top of the gasket conveyor belt 1. At this time, the supporting seat 2 that has just picked up the hardware gasket main body 44 is rotated to the top of the mold base conveyor belt 11, and then the gasket conveyor belt 1 and the mold base conveyor belt 11 are synchronously transmitted and moved to transfer the new hardware gasket main body 44 and the lower mold base 8 to the bottom of the two supporting seats 2. The hardware gasket main body 44 is picked up and assembled again in the above manner, and this reciprocating process is repeated, which greatly improves the work efficiency.
