Description

Technical Field

[0001] The invention belongs to the technical field of hydraulic hose assembly production, and in particular relates to a fully automatic crimping production device for a hydraulic hose assembly. Background Art

[0002] Fluid pipelines are channels for transferring fluid media. There are mainly two forms of pipelines: hoses and hard pipes, which transport fluids to other working components. They are one of the very important auxiliary components in the entire fluid operation system. Pipes need to be connected into sealed channels through different forms of joints for fluids to pass through, forming a circulation system. To form a circulation system, one end of the pipeline and the joint are combined and sealed, and the other end of the joint is connected to other joints or working components. The connection method between the pipeline and the joint is an important form for the normal passage of fluids. It must be ensured that the connection place can withstand the required pressure and has good permeability and sealing.

[0003] The hydraulic hose assembly is composed of hydraulic hoses and various types of joints through buckling. The hydraulic hose structure is mainly composed of a liquid-resistant synthetic rubber inner layer, a middle layer, a multi-layer reinforcement layer, and a weather-resistant synthetic rubber outer layer. The inner layer has the function of making the conveying medium withstand pressure and protecting the steel wire or wire fiber from erosion. The outer layer protects the reinforcement layer from damage. The reinforcement layer is a skeleton material and its function is to ensure the use pressure of the hydraulic hose.

[0004] Hydraulic hose assemblies are mainly used for mine hydraulic supports and oil field development. They are suitable for conveying petroleum-based (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (such as emulsions, oil-water emulsions, water) and liquid transmission with certain pressure and temperature in mechanized and automated hydraulic systems in engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, and various industrial departments. It has a wide range of uses and a large amount of use.

[0005] However, the current production of hydraulic hose assemblies can only rely on manual operation, and the production steps include cutting and blanking of raw tubes, pre-installation of joint sleeve cores, and crimping and forming.

[0018] Adopting the above technical scheme, the present invention is provided with eight hose clamping mechanisms, one of which is adjacent to and directly opposite to the hydraulic hose placement port, which is the hose installation station. Assuming that the hose clamping mechanism is the first hose clamping mechanism, the other seven hose clamping mechanisms are named in a clockwise direction (when looking down at the turntable) as the second hose clamping mechanism, the third hose clamping mechanism, the fourth hose clamping mechanism, the fifth hose clamping mechanism, the sixth hose clamping mechanism, the seventh hose clamping mechanism and the eighth hose clamping mechanism.

[0019] The specific working process of the present invention is as follows: an operator stands in front of the hydraulic hose placement port, and the operator installs the hose on the first hose clamping mechanism. If the hose is long, the hose is directly bent into a U-shape, and both ends of the U-shaped hose are extended upward into the mounting holes on the left and right sides of the positioning plate and contact the contact sensor. If the hose is short and not easy to bend into a U-shape, two shorter hoses can be taken at the same time and extended into the mounting holes on the left and right sides of the positioning plate respectively and contact the contact sensor. Since the upper end of the hose extended into the mounting hole on the left will bend to the right, and the upper end of the hose extended into the mounting hole on the right will bend to the left, the hose on the left is crimped with the arc-shaped correction groove of the correction positioning piece on the left, and the hose on the right is crimped with the arc-shaped correction groove of the correction positioning piece on the right, thereby Ensure that the upper end of the hose remains in a vertical setting; the contact sensor transmits the signal that the U-shaped hose is installed in place to the control system. After receiving the signal that the hose is installed in place, the control system sends a start signal to the left two-way synchronous clamping cylinder assembly and the right two-way synchronous clamping cylinder assembly of the hose clamping mechanism, and the two claws of the left two-way synchronous clamping cylinder assembly move toward each other at the same time, and the two semicircular grooves are combined into a cylindrical hole to clamp the hose on the left. At the same time, the two claws of the right two-way synchronous clamping cylinder assembly move toward each other at the same time, and the two semicircular grooves are combined into a cylindrical hole to clamp the hose on the right; then the telescopic rod of the positioning cylinder retracts upward, pulling the positioning plate upward, and the guide rod fixedly connected to the positioning plate moves upward along the guide sleeve until the mounting hole is separated from the upper end of the hose and the positioning cylinder stops retracting.

[0020] Then the servo motor starts, and the servo motor drives the turntable and the eight hose clamping mechanisms to rotate 45° counterclockwise (when looking down at the turntable) and then stop. The first hose clamping mechanism rotates to the left side of a set of sleeve automatic feeding and installation devices on the front side, and the second hose clamping mechanism rotates to the hose installation station. At this time, the telescopic rod of the positioning cylinder extends downward, driving the positioning plate to move downward to the initial positioning position, and the operator installs the hose on the second hose clamping mechanism (this process is the same as the process of installing the hose on the first hose clamping mechanism above, and will not be repeated); At the same time, the sleeve automatic feeding installation device installs the sleeve onto the upper end of the hose. The specific process of installing the sleeve is as follows: the sleeve automatic feeding vibration plate contains a number of sleeves of the same model, and the sleeve automatic feeding vibration plate conveys the sleeve to the right end of the first horizontal guide groove, and pushes the sleeve to the left through the first horizontal guide groove. After the leftmost sleeve touches the first limit sensor at the left end of the first horizontal guide groove, the first limit sensor sends a signal to the control system that the sleeve is in place, the sleeve automatic feeding vibration plate stops, and then the first synchronous belt drives horizontally. When the first clamping manipulator moves to the top of a sleeve at the far left end, the first vertical cylinder drives the first lifting and lowering sliding frame to move downward along the first vertical guide rail. After the first clamping manipulator clamps the sleeve, the first vertical cylinder drives the first lifting and lowering sliding frame to move upward along the first vertical guide rail. The first synchronous belt horizontal driving mechanism drives the first left and right sliding frames to move left along the two first left and right horizontal guide rails. The front and rear cylinders drive the first front and rear sliding frames to move forward along the first front and rear horizontal guide rail until the first clamping manipulator moves to the top of the hose. The first vertical cylinder drives the first lifting and lowering sliding frame to move downward along the first vertical guide rail. The first clamping manipulator on the first lifting and lowering sliding frame puts the sleeve downward onto the upper end of the hose; then the first clamping manipulator releases the sleeve, repeats the above action, clamps another sleeve and installs it to the other upper end of the hose. When the first clamping manipulator clamps the sleeve in the first horizontal guide groove, takes it away and installs it on the hose, the sleeve automatic feeding vibration plate pushes the sleeves to the left along the first horizontal guide groove for a distance of one sleeve and then stops.

[0021] After the sleeve is installed on the upper end of the hose on the first hose clamping mechanism, the servo motor is started again, and the servo motor drives the turntable and the eight hose clamping mechanisms to rotate 45° counterclockwise (when looking down at the turntable) and then stop. The first hose clamping mechanism rotates to the left side of a set of sleeve automatic feeding and installation devices on the rear side, the second hose clamping mechanism rotates to the left side of a set of sleeve automatic feeding and installation devices on the front side, and the third hose clamping mechanism rotates to the hose installation station. At this time, the telescopic rod of the positioning cylinder extends downward, driving the positioning plate to move downward to the initial positioning position , the operator installs the hose on the third hose clamping mechanism (this process is the same as the process of installing the hose on the first hose clamping mechanism above, and will not be repeated here); since a set of spare sleeve automatic feeding and installation devices on the rear side is temporarily not working, the first hose clamping mechanism does not need to be installed at this station, and a set of sleeve automatic feeding and installation devices on the front side installs the sleeve on the hose clamped by the second hose clamping mechanism. This operation process is the same as the operation process of installing the sleeve on the first hose clamping mechanism, and will not be repeated here.

[0022] Then the servo motor starts again, and the servo motor drives the turntable and the eight hose clamping mechanisms to rotate 45° counterclockwise (when looking down at the turntable) and then stop. The first hose clamping mechanism rotates to the core installation station on the front side of the core automatic feeding and installation device, the second hose clamping mechanism rotates to the left side of a set of sleeve automatic feeding and installation devices on the rear side, the third hose clamping mechanism rotates to the left side of a set of sleeve automatic feeding and installation devices on the front side, and the fourth hose clamping mechanism rotates to the hose installation station; at this time, the telescopic rod of the positioning cylinder extends downward, driving the positioning plate to move downward to At the initial positioning position, the operator installs the hose onto the fourth hose clamping mechanism (this process is the same as the process of installing the hose onto the first hose clamping mechanism above, so it will not be repeated); since the spare set of sleeve automatic feeding and installation devices on the rear side is temporarily not working, the second hose clamping mechanism does not need to be installed at this station, and the front set of sleeve automatic feeding and installation devices install the sleeve on the hose clamped by the third hose clamping mechanism. This operation process is the same as the operation process of installing the sleeve on the first hose clamping mechanism, so it will not be repeated here. The first hose clamping mechanism rotates to the core installation station, and the specific process of the core automatic feeding and installation device installing the core on the first hose clamping mechanism is as follows:

[0023] The core automatic feeding vibration plate contains several cores of the same model. The core automatic feeding vibration plate transports the core to the rear end entrance of the second horizontal guide trough, and pushes the core forward through the second horizontal guide trough. After a core on the front side touches the second limit sensor at the front end of the second horizontal guide trough, the second limit sensor sends a signal to the control system that the core is in place, and the core automatic feeding vibration plate stops. Then the second synchronous belt horizontal driving mechanism, the left and right cylinders and the second vertical cylinder are started. The second synchronous belt horizontal driving mechanism drives the second front and rear sliding frame to move backward along the two second front and rear horizontal guide rails, and the left and right cylinders drive the second left and right sliding frame to move to the left along the second left and right horizontal guide rails. When the second clamping manipulator moves to just above a core at the front end, the second vertical cylinder drives the second clamping manipulator to move to the left. The second lifting slide frame is driven to move downward along the second vertical guide rail. After the second clamping manipulator clamps the core, the second vertical cylinder drives the second lifting slide frame to move upward along the second vertical guide rail. The second synchronous belt horizontal drive mechanism drives the second front and rear slide frame to move rightward along the two second front and rear horizontal guide rails. The left and right cylinders drive the second left and right slide frames to move forward along the second left and right horizontal guide rails until the second clamping manipulator moves to the top of the hose. The second vertical cylinder drives the second lifting slide frame to move downward along the second vertical guide rail. The second clamping manipulator on the second lifting slide frame inserts the core downward into one of the upper ports of the hose. Then the second clamping manipulator releases the core and repeats the above action. The second clamping manipulator clamps another core and inserts it into the other upper port of the hose. In the process of the second clamping manipulator clamping the core in the second horizontal guide trough and removing it to install it on the hose, the core automatic feeding vibration plate pushes several cores forward along the second horizontal guide trough for a distance of one core and then stops.

[0024] Then the servo motor starts again, and the servo motor drives the turntable and the eight hose clamping mechanisms to rotate 45° counterclockwise (when looking down at the turntable) and then stop. The first hose clamping mechanism installed with the sleeve and the core rotates to the bottom of the first riveting press, the second hose clamping mechanism rotates to the core installation station on the front side of the core automatic feeding and installation device, the third hose clamping mechanism rotates to the left side of a set of sleeve automatic feeding and installation devices on the rear side, the fourth hose clamping mechanism rotates to the left side of a set of sleeve automatic feeding and installation devices on the front side, and the fifth hose clamping mechanism rotates to the hose installation station; at this time, the positioning cylinder The telescopic rod extends downward, driving the positioning plate to move downward to the initial positioning position, and the operator installs the hose on the fifth hose clamping mechanism (this process is the same as the process of installing the hose on the first hose clamping mechanism above, and will not be repeated); a set of sleeve automatic feeding and installation devices on the front side installs the sleeve on the hose clamped by the fourth hose clamping mechanism (this operation process is the same as the operation process of installing the sleeve on the first hose clamping mechanism, and will not be repeated here), and since a set of spare sleeve automatic feeding and installation devices on the rear side is temporarily not working, the third hose clamping mechanism does not need to be operated at this station The second hose clamping mechanism rotates to the core installation station, and the core automatic feeding and installation device performs the core installation on the second hose clamping mechanism. The specific process is the same as the process of installing the core on the first hose clamping mechanism, and no further description is given: the first hose clamping mechanism rotates to the riveting station under the first riveting machine, and the first riveting machine performs riveting (buttoning) operations on the core, sleeve and upper end of the hose on the first hose clamping mechanism. The specific riveting process is: the lifting cylinder is started, and the lifting cylinder drives the vertical slide to move upward along the vertical guide rail, and the left bidirectional synchronous The first clamping cylinder assembly and the right bidirectional synchronous clamping cylinder assembly also move upward, which drives the hose, sleeve and core to move upward to the inside of the riveting part at the bottom of the riveting press. The riveting press starts to crimp the core, sleeve and hose end into one piece, and then the lifting cylinder is started again. The lifting cylinder drives the vertical slide to move downward along the vertical guide rail to the initial position, and the left bidirectional synchronous clamping cylinder assembly and the right bidirectional synchronous clamping cylinder assembly fixed on the front side of the vertical slide also move downward, so that the crimped hose, sleeve and core are separated from the riveting press; the first riveting press only crimps one end of the hose.

[0025] Then the servo motor starts again, and the servo motor drives the turntable and the eight hose clamping mechanisms to rotate 45° counterclockwise (when looking down at the turntable) and then stop. The first hose clamping mechanism that buckles the sleeve, core and hose as one rotates to the position between the first riveting machine and the second riveting machine, and the second hose clamping mechanism installed with the sleeve and core rotates to the bottom of the first riveting machine. The third hose clamping mechanism rotates to the core installation station on the front side of the core automatic feeding and installation device, the fourth hose clamping mechanism rotates to the left side of a set of spare sleeve automatic feeding and installation devices on the rear side, the fifth hose clamping mechanism rotates to the left side of a set of sleeve automatic feeding and installation devices on the front side, and the sixth hose clamping mechanism rotates to the hose installation station; at this time, the telescopic rod of the positioning cylinder extends downward, driving the positioning plate to move downward to the initial positioning position, and the operator installs the hose on the sixth hose clamping mechanism (this process is the same as the process of installing the hose on the first hose clamping mechanism above, without 1. The second hose clamping mechanism rotates to the riveting station below the first riveting machine, and the first riveting machine performs riveting (buttoning) operations on the core, sleeve and upper end of the hose on the second hose clamping mechanism. The riveting operation process is the same as the riveting operation of the first riveting machine on the core, sleeve and hose on the second hose clamping mechanism, and the riveting operation process is the same as the riveting operation of the first riveting machine on the core, sleeve and hose on the second hose clamping mechanism, and the riveting operation process is the same as the riveting operation of the first riveting machine on the core, sleeve and hose on the second hose clamping mechanism, and the riveting operation process is the same as the riveting operation of the first riveting machine on the core, sleeve and hose on the second hose clamping mechanism, and the riveting operation process is the same as the riveting operation of the first riveting machine on the core, sleeve and hose on the second hose clamping mechanism, and the riveting operation process is the same as the riveting operation of the first riveting machine on the core, sleeve and hose on the second hose clamping mechanism, and the riveting operation process is the same as the riveting operation of the first riveting machine on the core, sleeve and hose on the second hose clamping mechanism, and the riveting operation process is the same as the riveting operation of the first riveting machine on the core, sleeve and hose on the second hose clamping mechanism, and the riveting operation process is the same as the riveting operation of the first riveting machine on the core, sleeve and hose on the second hose clamping mechanism, and the

[0026] Then the servo motor starts again, and the servo motor drives the turntable and the eight hose clamping mechanisms to rotate 45° counterclockwise (when looking down at the turntable) and then stop. The first hose clamping mechanism with one end of the hose buckled and connected to the sleeve and the core rotates to the bottom of the second riveting machine, and the second hose clamping mechanism with one end of the hose buckled and connected to the sleeve and the core rotates to the position between the first riveting machine and the second riveting machine. The third hose clamping mechanism with the sleeve and the core installed rotates to the right below the first riveting machine, and the fourth hose clamping mechanism rotates to the front of the automatic core feeding and installation device. At the core installation station on the side, the fifth hose clamping mechanism rotates to the left side of a set of spare sleeve automatic feeding and installation devices on the rear side, the sixth hose clamping mechanism rotates to the left side of a set of sleeve automatic feeding and installation devices on the front side, and the seventh hose clamping mechanism rotates to the hose installation station; at this time, the telescopic rod of the positioning cylinder extends downward, driving the positioning plate to move downward to the initial positioning position, and the operator installs the hose on the seventh hose clamping mechanism (this process is the same as the process of installing the hose on the first hose clamping mechanism above, and will not be repeated); a set of sleeve automatic feeding and installation on the front side The device performs a sleeve installation operation on the hose clamped by the sixth hose clamping mechanism (this operation process is the same as the operation process of installing the sleeve on the first hose clamping mechanism, which will not be repeated here). Since a set of sleeve automatic feeding and installation devices for spare at the rear side is temporarily not working, the fifth hose clamping mechanism does not need to perform installation operations on this position; the fourth hose clamping mechanism rotates to the core installation position, and the specific process of the core automatic feeding and installation device installing the core on the fourth hose clamping mechanism is the same as the process of installing the core on the first hose clamping mechanism, which will not be repeated here: the third hose clamping mechanism The tube clamping mechanism rotates to the riveting station under the first riveting machine, and the first riveting machine performs riveting (crocking) operations on the core, sleeve and upper end of the hose on the third hose clamping mechanism.

The fifth hose clamping mechanism rotates to the right below the first riveting press, the fifth hose clamping mechanism rotates to the core installation station on the front side of the core automatic feeding and installation device, the sixth hose clamping mechanism rotates to the left side of a set of spare sleeve automatic feeding and installation devices on the rear side, the seventh hose clamping mechanism rotates to the left side of a set of sleeve automatic feeding and installation devices on the front side, and the eighth hose clamping mechanism rotates to the hose installation station; at this time, the telescopic rod of the positioning cylinder extends downward, driving the positioning plate to move downward to the initial positioning position, and the operator installs the hose on the eighth hose clamping mechanism (this process is the same as the above process of installing the hose on the first hose clamping mechanism The process is the same as that of the seventh hose clamping mechanism, which will not be repeated here); a set of sleeve automatic feeding and installation devices on the front side installs the sleeve on the hose clamped by the seventh hose clamping mechanism (this operation process is the same as the operation process of installing the sleeve on the first hose clamping mechanism, which will not be repeated here), and since a set of sleeve automatic feeding and installation devices on the back side are temporarily not working, the sixth hose clamping mechanism does not need to be installed at this station; the fifth hose clamping mechanism rotates to the core installation station, and the specific process of the core automatic feeding and installation device installing the core on the fifth hose clamping mechanism is the same as that of the first hose clamping mechanism installing the core The process is the same and will not be repeated here: the fourth hose clamping mechanism rotates to the riveting station below the first riveting machine, and the first riveting machine performs riveting (buttoning) operations on the core, sleeve and upper end of the hose on the fourth hose clamping mechanism. The riveting operation process is the same as the riveting operation of the core, sleeve and hose on the first hose clamping mechanism by the first riveting machine, and will not be repeated here; the second riveting machine performs riveting operations on the unriveted end of the hose on the second hose clamping mechanism, and the riveting operation process is the same as the riveting operation of the core, sleeve and hose on the first hose clamping mechanism by the first riveting machine, and will not be repeated here;At the same time, the finished product automatic offline device presses both ends of the hose to connect the sleeve and the core to carry out offline conveying. The specific process of offline conveying is as follows: the offline synchronous belt horizontal drive mechanism starts, driving the slide to move to the right along the offline guide rail. When it moves into place, the offline synchronous belt horizontal drive mechanism stops. At this time, the center line of the long-distance radial cylinder is vertically crossed with the center line of the turntable. The long-distance radial cylinder on the slide drives the horizontal slide to move along the radial main guide toward the center of the turntable. When the long-distance radial cylinder extends to the set length, it stops, and the short-distance radial cylinder drives the two clamps through the linkage plate. The cylinder moves toward the center of the turntable along the radial support rail, and the two pairs of clamps set on the rear side of the clamp cylinder clamp the two hoses, and then the clamps of the left and right bidirectional synchronous clamping cylinder assemblies release the clamped hoses, and then the short-distance radial cylinder drives the two clamp cylinders to move to the left, and the long-distance radial cylinder drives the horizontal slide to move to the left. At the same time, the horizontal drive mechanism of the offline synchronous belt drives the slide to move to the left along the offline guide rail, so that the riveted hose products are transported out of the peripheral bracket, and the two pairs of clamps of the clamp cylinder release the two hoses, so that the finished hydraulic hose assembly is offline. ;

[0028] Then the servo motor starts again, and the servo motor drives the turntable and the eight hose clamping mechanisms to rotate 45° counterclockwise (when looking down at the turntable) and then stop. At this time, the turntable has rotated 360°, and the above working process is repeated, that is, the first hose clamping mechanism with no load (no hose clamped) rotates to the hose installation station, and the two ends of the hose are buckled and connected to the sleeve and the core. The second hose clamping mechanism rotates to the unloading station on the right rear side of the finished product automatic unloading device, and one end of the hose is buckled and connected to the sleeve and the core. The third hose clamping mechanism rotates The fourth hose clamping mechanism that is connected to the sleeve and the core by pressing one end of the hose is rotated to the position between the first riveting machine and the second riveting machine. The fifth hose clamping mechanism installed with the sleeve and the core is rotated to the position directly below the first riveting machine. The sixth hose clamping mechanism is rotated to the core installation position in front of the core automatic feeding and installation device. The seventh hose clamping mechanism is rotated to the left side of a spare sleeve automatic feeding and installation device at the rear side. The eighth hose clamping mechanism is rotated to a sleeve automatic feeding and installation device at the front side. The left side is placed; at this time, the telescopic rod of the positioning cylinder extends downward, driving the positioning plate to move downward to the initial positioning position, and the operator installs the hose on the first hose clamping mechanism; a set of sleeve automatic feeding and installation devices on the front side installs the sleeve on the hose clamped by the eighth hose clamping mechanism. Since the spare set of sleeve automatic feeding and installation devices on the rear side is temporarily not working, the seventh hose clamping mechanism does not need to be installed at this position; the sixth hose clamping mechanism rotates to the core installation position to install the core: the fifth hose clamping mechanism The structure rotates to the riveting station below the first riveting machine, and the first riveting machine performs riveting (crocking) operations on the core, sleeve and upper end of the hose on the fifth hose clamping mechanism; the second riveting machine performs riveting operations on the unriveted ends of the hoses on the third hose clamping mechanism; at the same time, the finished product automatic off-line device crimps both ends of the hose on the second hose clamping mechanism to connect the sleeve and the core to perform off-line conveying operations on the finished products. The specific procedures of the off-line conveying operations are the same as the off-line operations of the hoses on the first hose clamping mechanism mentioned above, and will not be repeated.

[0029] Then the turntable rotates and operates in a cycle, so that the hose, sleeve and core are installed, crimped and unloaded continuously.

[0030] The sleeve automatic feeding vibration plate and the core automatic feeding vibration plate are auxiliary feeding equipment for automatic assembly or automatic processing machinery, referred to as the parts feeding device. This is an existing mature technology, and the specific structure will not be described in detail. The working principle of the vibration plate: frequency converter, motor, to achieve automatic conveying.

[0031] The strokes of the cylinder and synchronous belt horizontal drive mechanism in the present invention are limited by sensors or limit switches. After receiving signals from the sensors or limit switches, the control system sends start and stop instructions to the cylinder and synchronous belt horizontal drive mechanism.

[0032] The riveting press is also a commonly used equipment, and the specific structure will not be described in detail.

[0033] Since the models of sleeves are different, a spare sleeve automatic loading and installation device is set up. The two sets of sleeve automatic loading and installation devices respectively contain different sleeves, which makes switching convenient.

[0034] The correction positioning piece serves to straighten the upper end of the hose and prevent it from tilting, making it convenient to insert the sleeve and the core vertically when installing them.

[0035] In summary, the hydraulic hose can realize a series of fully automated operations from pre-installed sleeves, cores, to crimping and offline. The outer bracket is equipped with a safety isolation device to ensure safe operation. The control system is operated by touch screen and automatically controlled to achieve coordinated and synchronous operation of the central rotating workbench, double-claw pneumatic clamping hose clamping mechanism, sleeve automatic feeding and installation device, core automatic feeding and installation device, automatic riveting device and finished product automatic offline device, which can greatly improve the crimping production efficiency of hydraulic hoses, sleeves and cores, and avoid problems such as manual missed crimping and inaccurate crimping dimensions.

[0036] The invention has reasonable design, simple structure, easy manufacturing and simple operation, and provides a fully automated production device for hydraulic hose crimping production. It has strong versatility, greatly improves the efficiency of hydraulic hose crimping operations, ensures crimping quality, has strong adaptability and is easy to promote and apply.

[0063] There are eight hose clamping mechanisms in the present invention, one of which is adjacent to and facing the hydraulic hose placement port 3, which is the hose installation station. Assuming that the hose clamping mechanism is the first hose clamping mechanism 62, the other seven hose clamping mechanisms are named in a clockwise direction (when looking down at the turntable 9) as the second hose clamping mechanism 63, the third hose clamping mechanism 64, the fourth hose clamping mechanism 65, the fifth hose clamping mechanism 66, the sixth hose clamping mechanism 67, the seventh hose clamping mechanism 68 and the eighth hose clamping mechanism 69.

[0064] The specific working process of the present invention is as follows: the operator stands at the front side of the hydraulic hose placement port 3, and the operator installs the hose 61 on the first hose clamping mechanism 62. If the hose 61 is long, the hose 61 is directly bent into a U shape, and both ends of the U-shaped hose 61 extend upward into the mounting holes on the left and right sides of the positioning plate 23 and contact the contact sensor 26. If the hose 61 is short and not easy to be bent into a U shape, two shorter hoses 61 can be taken at the same time and inserted into the mounting holes on the left and right sides of the positioning plate 23 respectively and contact the contact sensor 26. Since the upper end of the hose 61 inserted into the mounting hole on the left will bend to the right, and the upper end of the hose 61 inserted into the mounting hole on the right will bend to the left, the hose 61 on the left is crimped with the arc-shaped correction groove 79 of the left correction positioning piece 20, and the hose 61 on the right is crimped with the arc-shaped correction groove 79 of the right correction positioning piece 20, And ensure that the upper end of the hose 61 remains in a vertical setting; the contact sensor 26 transmits the signal that the U-shaped hose 61 is installed in place to the control system. After the control system receives the signal that the hose 61 is installed in place, it sends a start signal to the left bidirectional synchronous clamping cylinder assembly 16 and the right bidirectional synchronous clamping cylinder assembly 17 of the hose clamping mechanism, and the two claws 18 of the left bidirectional synchronous clamping cylinder assembly 16 move toward each other at the same time, and the two semicircular grooves are combined into a cylindrical hole to clamp the hose 61 on the left side. At the same time, the two claws 18 of the right bidirectional synchronous clamping cylinder assembly 17 move toward each other at the same time, and the two semicircular grooves are combined into a cylindrical hole to clamp the hose 61 on the right side; then the telescopic rod of the positioning cylinder 22 shrinks upward, pulling the positioning plate 23 upward, and the guide rod 25 fixedly connected to the positioning plate 23 moves upward along the guide sleeve 24 until the mounting hole is separated from the upper end of the hose 61 and the positioning cylinder 22 stops shrinking.

[0065] Then the servo motor 10 starts, and the servo motor 10 drives the turntable 9 and the eight hose clamping mechanisms to rotate 45° counterclockwise (when looking down at the turntable 9) and then stop. The first hose clamping mechanism 62 rotates to the left side of a set of sleeve automatic feeding and installation devices 5 on the front side, and the second hose clamping mechanism 63 rotates to the hose installation station. At this time, the telescopic rod of the positioning cylinder 22 extends downward, driving the positioning plate 23 to move downward to the initial positioning position, and the operator installs the hose 61 on the second hose clamping mechanism 63 (this process is the same as the process of installing the hose 61 on the first hose clamping mechanism 62 above, and will not be repeated); at the same time, the sleeve automatically The feeding installation device 5 installs the sleeve 70 onto the upper end of the hose 61. The specific process of installing the sleeve 70 is as follows: a plurality of sleeves 70 of the same model are contained in the sleeve automatic feeding vibration plate, and the sleeve automatic feeding vibration plate conveys the sleeve 70 to the right end of the first horizontal guide groove 28, and pushes the sleeve 70 to the left through the first horizontal guide groove 28. After the leftmost sleeve 70 touches the first limit sensor at the left end of the first horizontal guide groove 28, the first limit sensor sends a signal to the control system that the sleeve 70 is in place, and the sleeve automatic feeding vibration plate stops, and then the first synchronous belt horizontal drive mechanism 27, the front and rear cylinders 34 and the first vertical When the air cylinder 36 is started, the first synchronous belt horizontal driving mechanism 27 drives the first left and right sliding frame 29 to move rightward along the two first left and right horizontal guide rails 32, and the front and rear air cylinders 34 drive the first front and rear sliding frame 30 to move backward along the first front and rear horizontal guide rails 33. When the first clamping manipulator 37 moves to the top of the leftmost sleeve 70, the first vertical cylinder 36 drives the first lifting sliding frame 31 to move downward along the first vertical guide rail 35. After the first clamping manipulator 37 clamps the sleeve 70, the first vertical cylinder 36 drives the first lifting sliding frame 31 to move upward along the first vertical guide rail 35. The first synchronous belt horizontal driving mechanism The first left and right slide frame 29 is driven by the front and rear cylinders 34 to move forward along the first front and rear horizontal guide rails 33 until the first clamping manipulator 37 moves to the top of the rubber tube 61. The first vertical cylinder 36 drives the first lifting slide frame 31 to move downward along the first vertical guide rails 35. The first clamping manipulator 37 on the first lifting slide frame 31 sets the sleeve 70 downward onto the upper end of the rubber tube 61. Then the first clamping manipulator 37 releases the sleeve 70 and repeats the above action to clamp another sleeve 70 and install it on the other upper end of the rubber tube 61. In the process of the first clamping manipulator 37 clamping the sleeve 70 in the first horizontal guide groove 28 and removing it to install it on the rubber tube 61, the sleeve automatic feeding vibration plate pushes a plurality of sleeves 70 to the left along the first horizontal guide groove 28 by a distance of one sleeve 70 and then stops.

[0066] After the sleeve 70 is installed on the upper end of the hose 61, the servo motor 10 is started again, and the servo motor 10 drives the turntable 9 and the eight hose clamping mechanisms to rotate 45° counterclockwise (when looking down at the turntable 9) and then stop. The first hose clamping mechanism 62 rotates to the left side of a set of sleeve automatic feeding and installation devices 5 on the rear side, the second hose clamping mechanism 63 rotates to the left side of a set of sleeve automatic feeding and installation devices 5 on the front side, and the third hose clamping mechanism 64 rotates to the hose installation station. At this time, the telescopic rod of the positioning cylinder 22 extends downward, driving the positioning plate 23 to move downward to the initial positioning position, and the operator Install the hose 61 onto the third hose clamping mechanism 64 (this process is the same as the process of installing the hose 61 onto the first hose clamping mechanism 62 above, and will not be repeated here); since the spare set of sleeve automatic feeding and installation devices 5 on the rear side is temporarily not working, the first hose clamping mechanism 62 does not need to be installed at this work station, and the front set of sleeve automatic feeding and installation devices 5 installs the sleeve 70 on the hose 61 clamped by the second hose clamping mechanism 63. This operation process is the same as the operation process of installing the sleeve 70 on the first hose clamping mechanism 62, and will not be repeated here.

[0067] Then the servo motor 10 is started again, and the servo motor 10 drives the turntable 9 and the eight hose clamping mechanisms to rotate 45° counterclockwise (when looking down at the turntable 9) and then stop, the first hose clamping mechanism 62 rotates to the core installation station on the front side of the core automatic feeding and installation device 6, the second hose clamping mechanism 63 rotates to the left side of a set of sleeve automatic feeding and installation devices 5 on the rear side, the third hose clamping mechanism 64 rotates to the left side of a set of sleeve automatic feeding and installation devices 5 on the front side, and the fourth hose clamping mechanism 65 rotates to the hose installation station; at this time, the telescopic rod of the positioning cylinder 22 extends downward, driving the positioning plate 23 to move downward At the initial positioning position, the operator installs the hose 61 onto the fourth hose clamping mechanism 65 (this process is the same as the process of installing the hose 61 onto the first hose clamping mechanism 62, and will not be repeated); since the spare set of sleeve automatic feeding and installation devices 5 on the rear side is temporarily not working, the second hose clamping mechanism 63 does not need to be installed at this station, and the front set of sleeve automatic feeding and installation devices 5 install the sleeve 70 on the hose 61 clamped by the third hose clamping mechanism 64. This operation process is the same as the operation process of installing the sleeve 70 on the first hose clamping mechanism 62, and will not be repeated here. The first hose clamping mechanism 62 rotates to the core installation station, and the specific process of the core automatic feeding and installation device 6 installing the core 71 on the first hose clamping mechanism 62 is as follows:

[0068] The core automatic feeding vibration plate contains a number of cores 71 of the same model, and the core automatic feeding vibration plate transports the core 71 to the rear end entrance of the second horizontal guide trough 40, and pushes the core 71 forward through the second horizontal guide trough 40. After a core 71 at the front side touches the second limit sensor at the front end of the second horizontal guide trough 40, the second limit sensor sends a signal to the control system that the core 71 is in place, and the core automatic feeding vibration plate stops. Then the second synchronous belt horizontal drive mechanism 39, the left and right cylinders 46 and the second vertical cylinder 48 are started, and the second synchronous belt horizontal drive mechanism 39 drives the second front and rear sliding frame 42 to move backward along the two second front and rear horizontal guide rails 44, and the left and right cylinders 46 drive the second left and right sliding frame 41 to move left along the second left and right horizontal guide rails 45. When the second clamping manipulator 49 moves to just above a core 71 at the front end, the second vertical cylinder 48 drives the second lifting and sliding The frame 43 moves downward along the second vertical guide rail 47. After the second clamping manipulator 49 clamps the core 71, the second vertical cylinder 48 drives the second lifting slide frame 43 to move upward along the second vertical guide rail 47. The second synchronous belt horizontal drive mechanism 39 drives the second front and rear slide frame 42 to move rightward along the two second front and rear horizontal guide rails 44. The left and right cylinders 46 drive the second left and right slide frames 41 to move forward along the second left and right horizontal guide rails 45 until the second clamping manipulator 49 moves to the top of the hose 61. The second vertical cylinder 48 drives the second lifting slide frame 43 to move downward along the second vertical guide rail 47. The second clamping manipulator 49 on the second lifting slide frame 43 inserts the core 71 downward into one of the upper ports of the hose 61; then the second clamping manipulator 49 releases the core 71, and repeats the above actions. The second clamping manipulator 49 clamps another core 71 and inserts it into the other upper port of the hose 61. When the second clamping robot 49 clamps the core 71 in the second horizontal guide trough 40 and removes it to install it into the hose 61, the core automatic feeding vibration plate pushes the cores 71 forward along the second horizontal guide trough 40 by a distance of one core 71 and then stops.

[0069] Then the servo motor 10 is started again, and the servo motor 10 drives the turntable 9 and the eight hose clamping mechanisms to rotate 45° counterclockwise (when looking down at the turntable 9) and then stop, and the first hose clamping mechanism 62 installed with the sleeve 70 and the core 71 rotates to the bottom of the first riveting machine, the second hose clamping mechanism 63 rotates to the core 71 installation station on the front side of the core automatic feeding and installation device 6, the third hose clamping mechanism 64 rotates to the left side of a set of sleeve automatic feeding and installation devices 5 on the rear side, the fourth hose clamping mechanism 65 rotates to the left side of a set of sleeve automatic feeding and installation devices 5 on the front side, and the fifth hose clamping mechanism 66 rotates to the hose installation station; at this time, the telescopic rod of the positioning cylinder 22 The positioning plate 23 extends downward, driving the positioning plate 23 to move downward to the initial positioning position, and the operator installs the hose 61 onto the fifth hose clamping mechanism 66 (this process is the same as the process of installing the hose 61 onto the first hose clamping mechanism 62, and will not be repeated); a set of sleeve automatic feeding and installation devices 5 on the front side install the sleeve 70 on the hose 61 clamped by the fourth hose clamping mechanism 65 (this operation process is the same as the operation process of installing the sleeve 70 on the first hose clamping mechanism 62, and will not be repeated here), and since the set of sleeve automatic feeding and installation devices 5 on the back side are temporarily not working, the third hose clamping mechanism 64 does not need to be installed at this station; the second The hose clamping mechanism 63 rotates to the installation position of the core 71. The specific process of the core automatic feeding and installation device 6 installing the core 71 on the second hose clamping mechanism 63 is the same as the process of installing the core 71 on the first hose clamping mechanism 62, and no further description is given: the first hose clamping mechanism 62 rotates to the riveting position below the first riveting machine, and the first riveting machine performs riveting (buttoning) operations on the core 71, sleeve 70 and upper end of the hose 61 on the first hose clamping mechanism 62. The specific riveting process is: the lifting cylinder 15 is started, and the lifting cylinder 15 drives the vertical slide 14 to move upward along the vertical guide rail 13.

The riveting operation process is the same as the riveting operation of the first riveting machine on the core 71, sleeve 70 and hose 61 on the second hose clamping mechanism 63, which will not be repeated here.
