Description

Technical Field

[0001] The present invention belongs to the technical field related to riveting and pressing, and specifically discloses a silver contact assembly riveting and pressing device. Background Art

[0002] A riveting machine is a new type of riveting equipment developed based on the principle of cold rolling. It refers to a mechanical device that can rivet items with rivets. This equipment has a compact structure, stable performance, and convenient and safe operation. The riveting machine mainly relies on rotation and pressure to complete assembly and is mainly applied to occasions where rivets are required for riveting. Common types include pneumatic, hydraulic, and electric, as well as single-head and double-head specifications and models;

[0003] Most of the transmission riveting and pressing assembly equipment uses a vibrating disk for feeding to automatically transfer silver contacts. However, the positions of the silver contacts and the base cannot be accurately corresponding, and manual operation is required. Moreover, the base needs to be placed by hand, resulting in low efficiency and unstable quality. The assembled base is placed on one side of the workbench and needs to be sorted out later, which brings great inconvenience to production. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems existing in the background art, and a silver contact assembly riveting and pressing device is proposed, which includes a workbench, a vibrating feeding disk, and a riveting and pressing main machine. A base is arranged on the upper end surface of the workbench. A bracket is arranged on one side of the base. The outside of the bracket is connected to the riveting and pressing main machine through a lifting device arranged. The vibrating feeding disk is located on the upper end surface of the workbench and close to one side of the base. A feeding channel is arranged at one end of the vibrating feeding disk. A transfer rack is arranged at the front end of the feeding channel. A guiding mechanism is arranged on one side of the transfer rack. An operating platform is arranged on the upper end surface of the base. A positioning and feeding mechanism is arranged on the upper end surface of the operating platform. A delivery mechanism is arranged on the upper end surface of the base and close to one side of the operating platform.

[0005] Preferably, the guiding mechanism includes a machine base and a support base respectively fixedly arranged on one side of the upper end surface of the operating platform. One end inside the machine base is correspondingly connected to a sliding rod through a third cylinder arranged. A card slot is opened on the upper end surface of the sliding rod. A blocking piece is arranged on the side of the transfer rack away from the feeding channel. A communication slot is opened on the upper end surface of the machine base and close to the side of the transfer rack. One end of the communication slot is communicated with the card slot.

[0006] Preferably, a second hydraulic cylinder is arranged on one side of the support base. A support block is arranged at the telescopic end of the second hydraulic cylinder. A locking rod is connected to the telescopic end of a second cylinder through the upper end surface of the support block. A negative pressure device is clamped inside one end of the locking rod. One end of the negative pressure device is communicated and installed with a cartridge case. A groove adapted to adsorb the contact is opened inside the cartridge case.

[0007] Preferably, the positioning and feeding mechanism includes a frustum fixedly arranged on the upper end surface of the operating table. A backing plate is arranged on the upper end surface of the frustum near the middle. Rotating pressing components are arranged on both sides of the upper end surface of the backing plate.

[0008] Preferably, the rotating pressing component includes a T-shaped rod fixedly arranged. Mounting columns are vertically installed on the upper surfaces of both ends of the T-shaped rod. A rotating shaft is inserted through the upper part of the mounting column. An L-shaped frame is rotatably sleeved outside the rotating shaft. A pressing block is arranged on the inner surface of the L-shaped frame. A ball is arranged on the inner surface of the L-shaped frame near the pressing block.

[0009] Preferably, a positioning column is arranged on the upper end surface of the frustum near the space between the two T-shaped rods. The upper part inside the positioning column is hollow. An annular coiled pipe is arranged outside the positioning column. A plurality of air jet nozzles are connected and installed above the inside of the annular coiled pipe. An air pump is arranged on the side of the upper end surface of the frustum away from the two T-shaped rods. Air nozzles are connected and installed above and below the inside of the air pump. A roller frame is inserted into the front end of the frustum. A blanking frame is arranged on the outer wall of the front end of the operating table near the lower part of the roller frame. A controller is arranged on the upper end surface of one side of the workbench.

[0010] Preferably, the delivery mechanism includes a guide frame fixedly arranged on the upper end surface of the base away from the operating table side. A first hydraulic cylinder is arranged below the outside of the guide frame. A horizontally placed clamping rod is arranged at the telescopic end of the first hydraulic cylinder. The clamping rod is slidably matched with the guide frame. A first air cylinder is arranged on the lower end surface of one side of the clamping rod. An installation block is arranged at one end of the first air cylinder. A pneumatic clamp is arranged on the outer wall of the installation block.

[0011] Preferably, a frame platform is arranged on the upper end surface of the base near the clamping rod. A feeding frame is arranged on the upper end surface of the frame platform. A feeding channel for placing the base is opened above the inside of the feeding frame. The pneumatic clamp is located above one end of the feeding frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The vibrating feeding tray can automatically arrange and convey the silver contacts. The silver contacts reach the guiding mechanism through the blanking channel and the transfer rack. In the guiding mechanism, the third air cylinder pushes the sliding rod to push the silver contacts to the card shell. By using the adsorption effect of the air jet nozzles and the negative pressure device, the silver contacts are accurately transferred to the preset hole above the base. The whole process does not require manual intervention, improving the feeding efficiency and position accuracy.

[0014] By setting up the loading rack and cooperating with the first cylinder, the pneumatic clamp outside the front mounting block can be driven to translate, clamp the base placed above the loading rack, and then transport it to the two T-shaped rods at the conical platform. When the pneumatic clamp releases the base, the lower end face of the base will be in contact with the lower end balls of the L-shaped frame. When the base with a certain weight is clamped, the L-shaped frame sinks downward according to the weight, and the pressing block just presses against the two side walls of the base to clamp the base, so that the preset holes on the inner surface of the base accurately fall outside the positioning posts, and the lower end face of the base fits with the upper surface of the annular coil pipe. After the silver contacts are riveted, the annular coil pipe is blown at the lower end through the delivery of an external inflation device, causing the base to rise. After the base leaves the L-shaped frame, the L-shaped frame moves downward to one end of the mounting post according to the weight of the pressing block by itself. At this time, the air pump blows towards the base and blows the base towards the roller rack. Along with the guidance of the air flow, the riveted base moves towards the unloading rack. A box can be set at the lower end of the unloading rack for storage, thus reducing the subsequent steps of the finishing workbench. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner

[0025] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0026] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0027] As Figures 1-9 shown, a silver contact assembly and riveting equipment includes a workbench 1, a vibrating loading tray 3 and a riveting press main unit 4. A base 12 is arranged on the upper end surface of the workbench 1. A bracket is arranged on one side of the base 12. The outside of the bracket is connected to the riveting press main unit 4 through a lifting device 2 arranged thereon. The vibrating loading tray 3 is located on the upper end surface of the workbench 1 and close to one side of the base 12. A blanking channel 23 is arranged at one end of the vibrating loading tray 3. A transfer rack 15 is arranged at the front end of the blanking channel 23. A material guiding mechanism is arranged on one side of the transfer rack 15. An operation console 8 is arranged on the upper end surface of the base 12. A positioning and feeding mechanism is arranged on the upper end surface of the operation console 8. A delivery mechanism is arranged on the upper end surface of the base 12 and close to one side of the operation console 8.

[0028] The material guiding mechanism includes a machine base 24 and a support seat 25 which are respectively fixedly arranged on one side of the upper end surface of the operation console 8. One end inside the machine base 24 is correspondingly connected to a sliding rod 39 through a third cylinder 18 arranged thereon. A card slot 37 is opened on the upper end surface of the sliding rod 39. A retaining piece 38 is arranged on the side of the transfer rack 15 away from the blanking channel 23. A communication groove is opened on the upper end surface of the machine base 24 and close to the side of the transfer rack 15. One end of the communication groove is communicated with the card slot 37. One end of the retaining piece 38 covers the upper part of the communication groove. The purpose is to prevent the protrusion above the silver contact when the silver contact slides to the communication groove, limit it, and ensure the neat and orderly movement of the silver contact.

[0029] On one side of the support base 25, there is a second hydraulic cylinder 22. At the telescopic end of the second hydraulic cylinder 22, there is a support block 41. The upper end surface of the support block 41 is connected to a locking rod 14 through the telescopic end of a second cylinder 7. Inside one end of the locking rod 14, there is a negative pressure device 40 installed in a clamping manner. One end of the negative pressure device 40 is connected and installed with a cartridge case 36. Inside the cartridge case 36, there is a groove adapted for contact adsorption.

[0030] After the vibrating feeding tray 3 is started, the silver contacts are automatically arranged and then transmitted to the transfer rack 15 through the feeding channel 23. The silver contacts move forward neatly and orderly, slide into the card slot 37 inside the slide rod 39 through the communication slot, and the third cylinder 18 pushes the slide rod 39 to the front end of the negative pressure device 40. The negative pressure device 40 adsorbs the silver contacts to the cartridge case 36 and pushes them above the base through the second cylinder 7.

[0031] It should be specifically noted that the groove inside the cartridge case 36 abuts against the outer edge of one side of the silver contact. When the negative pressure device 40 does not produce an adsorption effect, the silver contacts can slide off from here by themselves, without interfering with the feeding of the silver contacts.

[0032] The positioning and feeding mechanism includes a round table 16 fixedly arranged on the upper end surface of the operating table 8. Near the middle of the upper end surface of the round table 16, there is a backing plate 27. On both sides of the upper end surface of the backing plate 27, there are rotation and pressing components. The round table 16 corresponds to the riveting press main body 4, and the corresponding rotation and pressing components are arranged at the lower end of the riveting press main body 4.

[0033] The rotation and pressing component includes a T-shaped rod 29 fixedly arranged. On the upper surfaces of both ends of the T-shaped rod 29, there are vertically installed mounting columns 34. Inside the upper part of the mounting columns 34, there is a rotating shaft 35 inserted. Outside the rotating shaft 35, there is an L-shaped frame 32 rotatably sleeved. On the inner surface of the L-shaped frame 32, there is a pressing block 31. On the inner surface of the L-shaped frame 32 and on one side close to the pressing block 31, there are balls 33.

[0034] Since the L-shaped frame 32 itself is rotatably connected to the mounting column 34 through the rotating shaft 35, therefore, for the pressing block 31 at the upper end and the protruding part of the L-shaped frame 32 itself, when the L-shaped frame 32 cannot be contacted, the L-shaped frame 32 will press down towards the pressing block 31 due to its weight. When the base presses down to the lower end of the L-shaped frame 32, the base sinks along with the L-shaped frame 32, prompting the pressing block 31 on the inner surface of the L-shaped frame 32 to press against the outside of the base, thus automatically completing the positioning of the base and also enabling the preset hole on the inner surface of the base to accurately abut against the positioning column.

[0035] On the upper end surface of the frustum 16 and near the two T-shaped rods 29, a positioning column is provided. The upper part inside the positioning column is hollow, and an annular coiled pipe 30 is arranged outside the positioning column. A plurality of air nozzles 28 are connected and installed above the inside of the annular coiled pipe 30. On the upper end surface of the frustum 16 and on one side far from the two T-shaped rods 29, an air pump 26 is provided. Air nozzles are connected and installed at both the upper and lower parts inside the air pump 26. A roller frame 17 is inserted into the front end of the frustum 16. A blanking frame 9 is arranged on the front outer wall of the operating table 8 and below the roller frame 17. A controller 10 is arranged on the upper end surface of one side of the workbench 1;

[0036] The upper part inside the positioning column is hollow, which can facilitate positioning the silver contact, enabling the lower end of the silver contact to accurately align with the preset hole of the base. During subsequent riveting, the silver contact can be pressed against, allowing the silver contact to be riveted to the base;

[0037] The annular coiled pipe 30 is connected to an external inflation device, which can blow the base from below, enabling the base to rise and eject. Due to the balls 33 of the L-shaped frame 32, the base can move smoothly upward. When there is no base pressing against the L-shaped frame 32, it rotates towards the side of the pressing block 31. At this time, the base is pushed upward. The air pump 26 blows the base through the air nozzles, causing the base to fall to the roller frame 17. Finally, the riveted base is automatically guided to fall at one end through the blanking frame 9;

[0038] The controller 10 can control each driving element.

[0039] The delivery mechanism includes a guide frame 11 fixedly arranged on the upper end surface of the base 12 and on the side far from the operating table 8. A first hydraulic cylinder 21 is arranged below the outside of the guide frame 11. A horizontally placed clamping rod 5 is arranged at the telescopic end of the first hydraulic cylinder 21. The clamping rod 5 is slidably matched with the guide frame 11. A first air cylinder 6 is arranged on the lower end surface of one side of the clamping rod 5. An installation block is arranged at one end of the first air cylinder 6. A pneumatic clamp 19 is arranged on the outer wall of the installation block;

[0040] The first hydraulic cylinder 21 can drive the clamping rod 5 to slide flexibly, causing the pneumatic clamp 19 to move up and down, facilitating clamping the base and subsequent discharging. By setting the first air cylinder 6, the front installation block can be driven to move horizontally, enabling the pneumatic clamp 19 to move the clamped base towards one side of the frustum 16.

[0041] A frame platform 13 is arranged on the upper end surface of the base 12 and near the clamping rod 5. A feeding frame 20 is arranged on the upper end surface of the frame platform 13. A feeding channel for placing the base is opened above the inside of the feeding frame 20. The pneumatic clamp 19 is located above one end of the feeding frame 20;

[0042] The frame platform 13 is used to support the feeding frame 20. The feeding channel arranged inside the feeding frame 20 is convenient for placing multiple groups of bases, enabling the pneumatic clamp 19 to sequentially clamp the bases and move them for feeding.

[0043] Working principle: When in use, the base needs to be placed first. Driven by the first cylinder 6, the front mounting block and the pneumatic clamp 19 are driven to move to the feeding rack 20. The first hydraulic cylinder 21 controls the pneumatic clamp 19 to clamp the base through lifting. After clamping, the first cylinder 6 conveys it to the upper side of one side of the conical table 16, and controls the base to move down to the middle of the four groups of L-shaped frames 32. When the pneumatic clamp 19 releases the limit on the base, the base fits with the balls 33 on the inner surface of the lower end of the L-shaped frame 32. The rolling fit of the balls 33 enables the base to sink to the lower ends of the four groups of L-shaped frames 32. As the base sinks, the weight of the lower ends of the L-shaped frames 32 increases, causing the L-shaped frames 32 to tilt downward and press, and the pressing blocks 31 on the corresponding upper inner surface abut against the inner surface of the base. When the base is stably clamped, the silver contacts need to be transported;

[0044] After the vibrating feeding tray 3 is started, the silver contacts are arranged and transmitted to the transfer rack 15 through the feeding channel 23. The silver contacts move forward neatly and orderly. The silver contacts at one end of the transfer rack 15 slide into the clamping grooves 37 at the sliding rod 39 through the communication grooves. The third cylinder 18 pushes the sliding rod 39 to the front end of the negative pressure device 40. The negative pressure device 40 adsorbs the silver contacts to the cartridge case 36 and is pushed to the upper side of the base by the second cylinder 7. Under the lifting adjustment of the second hydraulic cylinder 22, the silver contacts fall to the hollow part of the positioning column. When the position of the silver contacts is determined, the lifting device 2 drives the riveting main machine 4 to move down, and hammers the upper edge of the silver contacts, causing the silver contacts to be riveted to the base;

[0045] After riveting is completed, the annular coiled pipe 30 blows air to make the base rise away from the L-shaped frame 32. The L-shaped frame 32 moves down due to its own weight, and the air pump 26 blows the base to make it fall to the roller rack 17, and finally the blanking is completed through the blanking rack 9.

[0046] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
