Description

Technical Field

[0001] This utility model belongs to the field of crimp nut processing technology, specifically relating to a crimp nut slotting processing loading and unloading device. Background Technology

[0002] Press-fit nuts are a type of fastener commonly used in the mechanical field. For the slotting process of hexagonal press-fit nuts, the processing equipment is a single-function machine. It is necessary to process an annular groove on the central through groove of the press-fit nut as a blank groove for the thread. The loading and unloading method used in the slotting process is manual single-piece loading and unloading. This method has low processing efficiency, high manual labor intensity, and makes it difficult to maintain the production rhythm. Utility Model Content

[0003] In view of the defects of the prior art, the purpose of this utility model is to provide a loading and unloading device for slotting nut processing, which can realize automatic loading and unloading of the slotting process.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a device for loading and unloading crimped nuts for slotting processing, comprising a vibratory feeder, a discharge channel, a slide table, a loading cylinder, a chuck, and a unloading cylinder; the crimped nuts to be slotted are placed in the hopper of the vibratory feeder, the outlet of the vibratory feeder is connected to the inlet of the discharge channel, the outlet of the discharge channel extends to the loading groove of the slide table, the loading groove is correspondingly provided with a loading cylinder, the loading cylinder is fixed on the slide table, the loading cylinder moves synchronously with the slide table to approach or move away from the chuck, the loading cylinder is used to push the crimped nuts in the loading groove onto the chuck and clamp them by the chuck, completing the loading; after the crimped nuts are processed by the slotting process, the telescopic rod of the unloading cylinder extends into the central through groove of the crimped nuts, after the chuck is relaxed, the crimped nuts are hung on the telescopic rod of the unloading cylinder, the telescopic rod of the unloading cylinder retracts, completing the unloading.

[0005] Based on the above technical solution, the vibratory plate torsional vibration makes the large and small ends of all the clamping nuts face the same direction, so that the clamping nuts can enter the processing position in a uniform state according to the position requirements of the groove processing. The function of the vibratory plate is to orderly and neatly send the disordered workpieces into the discharge channel through vibration. The inner cavity of the discharge channel is adapted to the clamping nuts, restricting the change of the clamping nut posture, so that the clamping nuts enter the feeding groove in a predetermined posture.

[0006] Furthermore, the feeding and unloading device for slotting and machining crimping nuts also includes a feeding cylinder, which is fixed on a base. A slide rail is provided on the upper surface of the base. The telescopic end of the feeding cylinder is connected to a slide table to control the slide table to slide on the slide rail. The slide table is used to drive the feeding trough and the feeding cylinder to reciprocate between the feeding station and the loading station. When the feeding cylinder retracts, the feeding trough and the feeding cylinder are in the feeding station away from the chuck. When the feeding cylinder extends, the feeding trough and the feeding cylinder are in the loading station in front of the chuck. The outlet end of the discharge channel is located above the feeding trough in the feeding station. When the feeding trough is in the loading station, the feeding cylinder pushes the crimping nuts in the feeding trough onto the chuck.

[0007] Based on the above technical solution, the feeding cylinder and slide can avoid the processing position in front of the chuck after the material is fed, providing working space for the processing tools of the grooving process.

[0008] Furthermore, the inner wall of the feeding trough is adapted to the outer wall of the clamping nut, the axis of the feeding cylinder coincides with the center line of the feeding trough, the telescopic rod of the feeding cylinder acts on the end face of the clamping nut to push the clamping nut, and a limit plate is provided on the side of the feeding trough away from the feeding cylinder, and the limit plate is fixed on the base.

[0009] Furthermore, the limiting plate has an L-shaped structure. The vertical part of the limiting plate is located on the side of the feeding trough away from the feeding cylinder, and the horizontal part of the limiting plate is located above the feeding trough. The outlet of the discharge channel is fixed on the horizontal part of the limiting plate. The horizontal part of the limiting plate has a through hole, and the clamping nut of the discharge channel outlet enters the feeding trough through the through hole.

[0010] Furthermore, the discharge channel includes an inclined channel and a vertical channel. The inclined channel is horizontally inclined downwards. One end of the inclined channel is connected to the hopper outlet of the vibratory feeder, and the other end of the inclined channel is connected to the vertical channel. The outlet of the vertical channel is located above the feeding trough. The inner cavity of the vertical channel is adapted to the shape of the clamping nut.

[0011] Based on the above technical solution, the vertical channel is formed by several adjustment plate plates connected by columns. The adjustment plate plates are provided with corresponding adjustment holes. The adjustment holes have large end holes and small end holes that are adapted to the clamping nut. The adjustment holes play a role in restricting and adjusting the posture of the clamping nut.

[0012] Furthermore, the end of the telescopic rod of the feeding cylinder is connected to a hanging rod. When the feeding cylinder extends, the hanging rod extends into the central through groove of the clamping nut and hangs the clamping nut.

[0013] Furthermore, the hanging rod is inclined downward along the direction close to the feeding cylinder, and a baffle is provided in front of the feeding cylinder. The baffle has a retaining groove, the width of which is smaller than the outer diameter of the clamping nut. The retaining groove allows the telescopic rod of the feeding cylinder and the hanging rod to pass through, while restricting the passage of the clamping nut, so that the clamping nut hanging on the hanging rod is separated from the hanging rod.

[0014] Based on the above technical solution, the central through groove of the clamping nut is a through groove, and the hanging rod is set at an inclination. The clamping nut can slide down to the lowest point at the end of the hanging rod, which prevents the clamping nut from falling off prematurely when the feeding cylinder telescopic rod retracts. When the feeding cylinder telescopic rod retracts, the clamping nut is restricted from passing through the baffle groove, so the baffle pushes the clamping nut to separate from the hanging rod.

[0015] Furthermore, a downward-sloping material discharge channel is provided below the baffle, and the end of the material discharge channel is connected to a storage box.

[0016] Furthermore, the feeding cylinder and the baffle are fixed on the feeding cylinder bracket, and the feeding cylinder bracket is provided with an arc-shaped connecting hole for adjusting the installation angle.

[0017] Furthermore, the chuck is pneumatically driven to clamp onto the outer wall of the snap-fit ​​nut.

[0018] The beneficial effects of this utility model are as follows: the posture adjustment and feeding of the crimping nut are realized through the vibrating plate and the discharge channel, and the automatic feeding and unloading process of the chuck is realized through the feeding cylinder and the unloading cylinder, thus completing the automatic loading and unloading of the crimping nut slotting process. One person can operate multiple machines, which can improve efficiency and reduce costs, and effectively ensure the production cycle. Attached Figure Description

[0028] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0029] See appendix Figure 1-8A device for loading and unloading grooving nuts includes a vibratory feeder 1, a discharge channel 2, a slide 3, a feeding cylinder 4, a loading cylinder 5, a chuck 6, and a unloading cylinder 7. The grooving nuts to be grooved are placed in the hopper of the vibratory feeder 1. The outlet of the hopper of the vibratory feeder 1 is connected to the inlet of the discharge channel 2. The outlet of the discharge channel 2 extends into the loading groove 301 of the slide 3. The loading groove 301 is correspondingly equipped with the loading cylinder 5, which is fixed on the slide 3. The telescopic end of the feeding cylinder 4 is connected to the slide 3 to control the slide 3 to move closer to or away from the chuck. 6. The feeding cylinder 5 moves synchronously with the slide table 3 to approach or move away from the chuck 6. The feeding cylinder 5 is used to push the clamping nut in the feeding groove 301 onto the chuck 6. The chuck 6 is pneumatically driven to clamp the clamping nut on the outer wall of the outer side, automatically centering and clamping to complete the feeding. After the clamping nut is processed by the grooving process, the end of the telescopic rod of the unloading cylinder 7 is connected to the hanging rod 11. When the unloading cylinder 7 extends, the hanging rod 11 extends into the central through groove of the clamping nut. After the chuck 6 relaxes, the clamping nut is hung on the hanging rod 11, and the unloading cylinder 7 retracts to complete the unloading.

[0030] Based on the above technical solution, the vibratory feeder 1 uses torsional vibration to align the large and small ends of all the clamping nuts, ensuring they enter the processing position in a uniform manner according to the requirements of the grooved processing. The function of the vibratory feeder 1 is to orderly and neatly arrange the disordered workpieces into the discharge channel 2 through vibration. The inner cavity of the discharge channel 2 is adapted to the clamping nuts, restricting the change in the posture of the clamping nuts and ensuring they enter the feeding groove 301 in a predetermined posture. Commercially available brands of vibratory feeders can be used. The processing tool for the central through groove of the clamping nut is an 8*12-200L stainless steel blade, a hand-ground tool, a special tool, ground according to the different groove shapes of the product. Figure 1-2 The positions of the machining tools shown are for illustrative purposes only. The feed and retraction of the machining tools are controlled by the machine tool, and the specific machining feed method is not within the scope of protection of this utility model. The chuck is the main structure of the original single-function nut-pressing machine. The loading and unloading device of this utility model is used in conjunction with the chuck of the single-function nut-pressing machine for loading and unloading. The grooving process forms a hollow groove for the thread. When the nut is assembled and used, it can tighten the bottom contact surface of the thread on the handpiece. At the same time, the grooving process can thin the wall thickness of the pressing part, making pressing easier.

[0031] Furthermore, the feeding cylinder 4 is fixed on the base 8, and a slide rail 9 is provided on the upper surface of the base 8. The telescopic end of the feeding cylinder 4 is connected to the slide table 3 to control the slide table 3 to slide on the slide rail 9. The slide table 3 is used to drive the feeding trough 301 and the feeding cylinder 5 to reciprocate between the feeding station and the loading station. When the feeding cylinder 4 retracts, the feeding trough 301 and the feeding cylinder 5 are in the feeding station away from the chuck 6. When the feeding cylinder 4 extends, the feeding trough 301 and the feeding cylinder 5 move to the loading station in front of the chuck 6. The outlet end of the discharge channel 2 is set above the feeding trough 301 in the feeding station. When the feeding trough 301 is in the loading station, the feeding cylinder 5 pushes the clamping nut in the feeding trough 301 onto the chuck 6.

[0032] Based on the above technical solution, the feeding cylinder 4 and the slide table 3 are positioned to avoid the machining position in front of the chuck 6 after the material is loaded, providing working space for the machining tools in the grooving process. The base 8 is connected to the bottom platform 17 by bolts, and the position of the base 8 can be adjusted to adjust the position of the feeding station and the loading station to match the chuck 6.

[0033] Furthermore, the inner wall of the feeding trough 301 is adapted to the outer wall of the clamping nut, the axis of the feeding cylinder 5 coincides with the center line of the feeding trough 301, the telescopic rod of the feeding cylinder 5 acts on the end face of the clamping nut to push the clamping nut, and a limiting plate 10 is provided on the side of the feeding trough 301 away from the feeding cylinder 5, the limiting plate 10 is fixed on the base 8. The limiting plate 10 has an L-shaped structure, the vertical part of the limiting plate is provided on the side of the feeding trough 301 away from the feeding cylinder 5, the horizontal part of the limiting plate 10 is provided above the feeding trough 301, the outlet of the discharge channel 2 is fixed on the horizontal part of the limiting plate 10, and the horizontal part of the limiting plate 10 has a through hole 1001, through which the clamping nut at the outlet of the discharge channel 2 enters the feeding trough 301.

[0034] Based on the above technical solution, the feeding trough 301 can only accommodate one clamping nut. When the feeding trough 301 moves to the feeding station with the slide table 3, the limiting plate 10 remains stationary, and the bottom of the through hole 1001 is closed on the upper surface of the slide table 3. The next clamping nut enters the closed through hole 1001 and waits to enter the feeding station. The clamping nut is a hexagonal clamping nut, and the outer wall of the large end of the clamping nut is a hexagonal structure. The inner wall of the feeding trough 301 is a polygonal structure adapted to the hexagonal clamping nut.

[0035] Furthermore, the discharge channel 2 includes an inclined channel 201 and a vertical channel 202. The inclined channel 201 is horizontally inclined downwards. One end of the inclined channel 201 is connected to the hopper outlet of the vibrating plate 1, and the other end of the inclined channel 201 is connected to the vertical channel 202. The outlet of the vertical channel 202 is located above the feeding trough 301. The inner cavity of the vertical channel is adapted to the shape of the snap-fit ​​nut.

[0036] Based on the above technical solution, the vertical channel 202 is formed by a number of adjustment hole plates connected by columns. The adjustment hole plates are provided with corresponding adjustment holes. The adjustment holes have large end holes and small end holes that are adapted to the clamping nut. The adjustment holes play a role in restricting the adjustment of the clamping nut's posture.

[0037] Furthermore, the hanging rod 11 is inclined downward along the direction close to the feeding cylinder 7, and a baffle 12 is provided in front of the feeding cylinder 7. A retaining groove 1201 is provided on the baffle 12. The width of the retaining groove 1201 is smaller than the outer diameter of the clamping nut. The retaining groove 1201 allows the telescopic rod of the feeding cylinder 7 and the hanging rod 11 to pass through, while restricting the passage of the clamping nut, so that the clamping nut hanging on the hanging rod 11 is separated from the hanging rod.

[0038] Based on the above technical solution, the central through groove of the clamping nut is a through groove, and the hanging rod 11 is inclined. The clamping nut can slide down to the lowest point of the end of the hanging rod, so as to prevent the clamping nut from falling off prematurely when the telescopic rod of the feeding cylinder 7 retracts. When the telescopic rod of the feeding cylinder retracts, the baffle 12 pushes the clamping nut to separate from the hanging rod 11 because the baffle groove 1201 restricts the passage of the clamping nut.

[0039] Furthermore, a downwardly inclined material discharge channel 13 is provided below the baffle 12, and the end of the material discharge channel 13 is connected to the storage box 14; the material discharge cylinder 7 and the baffle 12 are fixed on the material discharge cylinder bracket 15, the material discharge cylinder bracket 15 is provided with an arc-shaped connecting hole 1501 for adjusting the angle, and the material discharge cylinder bracket 15 is provided with a fixing screw hole 1502, and the material discharge cylinder bracket 15 is bolted to the bottom platform 17 through the fixing screw hole 1502. In order to facilitate tool processing, the tool and tool holder are located in front of the chuck 6, so the material discharge cylinder 7 can be offset from the front of the chuck 6. By adjusting the angle of the material discharge cylinder 7 through the arc-shaped connecting hole 1501 of the material discharge cylinder bracket 15, the hanging rod 11 can pass through the central through slot of the clamping nut.

[0040] Working process: Vibratory feeder 1 feeds the product, which is then sorted by the horizontal rotating channel. The clamping nuts in vibratory feeder 1 are sequentially discharged and arranged into inclined channel 201 and vertical channel 202. The clamping nuts exiting vertical channel 202 enter the feeding trough 301 on the slide at the feeding station one by one. Feeding cylinder 4 extends, and the clamping nuts to be processed in feeding trough 301, along with feeding cylinder 5, move forward to the feeding station in front of chuck 6. Feeding cylinder 5 extends, pushing the clamping nuts to be processed in feeding trough 301 onto chuck 6. Chuck 6... The clamping cylinder 5 and the feeding cylinder 4 retract, and the next clamping nut enters the feeding slot 301 to await loading. The machining tool 16 moves forward to cut a groove in the clamping nut. After machining, the machining tool 16 retracts, the unloading cylinder 7 extends, and the hanging rod 11 extends into the center slot of the clamping nut. The chuck 6 loosens, and the clamping nut hangs on the hanging rod 11. The unloading cylinder 7 retracts, and the clamping nut on the hanging rod 11 slides down into the unloading channel 13 due to the obstruction of the baffle 12, and enters the storage box 14 through the unloading channel 13. The above steps are repeated to complete the automatic loading and unloading process of the clamping nut groove cutting.
