Description

Technical Field

[0001] This invention belongs to the field of feeding technology for adjusting bolt forming machine tools, and particularly relates to an automatic feeding device for adjusting bolt forming machine tools. Background Technology

[0002] In the field of feeding equipment for adjusting bolt forming machine tools, most of the automatic feeding mechanisms currently configured on these machines adopt a mechanical clamping and conveying method, relying on slot limits to complete the transfer of bolt blanks. This type of structure does not have magnetic positioning capability, and the blank is prone to slippage and falling during the tilting and rotation of the turntable. The feeding rhythm is unstable and cannot match the high-speed production conditions of continuous forming of adjusting bolts.

[0003] Existing feeding equipment for adjusting bolt processing machine tools mostly uses fixed, integrated feeding channels with inflexible channel spacing, limiting its capacity to conveying adjusting bolt blanks of a single specification. When producing adjusting bolts of different sizes and diameters, the entire feeding channel component must be disassembled and modified, resulting in a cumbersome debugging process that severely impacts the overall production changeover efficiency of the machine tool and restricts its applicability.

[0004] Traditional adjustable bolt machining centers feature compact, integrated feeding turntables with tightly connected internal and external transmission components, making disassembly and replacement difficult. Furthermore, they generally lack clutch and clearance mechanisms. Once the blank is in place, the feeding structure cannot retract, easily causing positional interference with the machine tool's internal forming molds and cutting tools. This not only affects the accuracy of the adjustable bolt machining but also easily leads to damage to equipment components, resulting in insufficient overall automation adaptability. Summary of the Invention

[0005] To address the problems existing in the prior art, this invention provides an automatic feeding device for adjusting bolt processing machine tools. The purpose is to overcome the shortcomings of the prior art and provide a magnetically adjustable clutch automatic feeding device. It achieves stable feeding without rigid jamming through a magnetically synchronous transmission structure, adapts to multiple specifications of blanks through a laterally adjustable elastic feeding channel, achieves machining station avoidance through a lifting clutch structure, and enables quick shape change through a quick-release outer turntable. The overall structure is compact, reliable in operation, highly versatile, and easy to maintain.

[0006] This invention is implemented as follows: an automatic feeding device for a bolt processing machine tool includes a base, a vertical lifting bracket, a drive slider that can slide up and down along the vertical lifting bracket, a drive motor mounted on the drive slider, a coaxial magnetic transmission assembly, a feeding channel assembly, and a stripping partition. The coaxial magnetic transmission assembly includes a connecting plate fixedly connected to the output shaft of the drive motor, a magnetic ring fixed to the outside of the connecting plate, and an outer feeding turntable movably sleeved outside the magnetic ring. An annular gap is left between the magnetic ring and the outer feeding turntable, and a limiting engagement structure is provided between the two to achieve synchronous circumferential rotation. The feeding channel assembly is located above the base and includes a base plate, a transverse slide rail opened on the base plate, and two sets of feeding side plates that can slide relative to each other along the transverse slide rail. An elastic pushing structure is assembled between the two feeding side plates. The stripping partition is fixedly arranged with one end extending into the annular gap. The outer circumference of the outer feeding turntable is provided with external transmission teeth, and a meshing rack that can cooperate with the external transmission teeth is fixed on the feeding side plate.

[0007] Preferably, the vertical lifting bracket is threaded with a stud, and a first limiting plate is fixedly connected to the stud. The first limiting plate is attached to the outer feeding turntable and one of the feeding side plates. A detachable second limiting plate is installed on the other side of the base plate, and the second limiting plate is attached to the outer feeding turntable and the other feeding side plate. The second limiting plate axially limits the outer feeding turntable, and the outer feeding turntable can be removed laterally after the axial end limiting member is removed.

[0009] As a preferred embodiment of the present invention, it further includes a lifting drive component fixedly installed on the base, the lifting drive component being connected to a drive slider to drive the drive slider to complete the lifting action.

[0010] As a preferred embodiment of the present invention, the limiting engagement structure consists of a transmission limiting notch formed on the outer wall of the magnet ring and a transmission limiting block fixed on the inner wall of the outer feeding turntable. The transmission limiting block is engaged in the transmission limiting notch to achieve torque transmission.

[0011] As a preferred embodiment of the present invention, the elastic pushing structure is an elastic pushing member, which is installed at the bottom of the two feed side plates and normally pushes the two sets of feed side plates to move closer to each other.

[0012] In a preferred embodiment of the present invention, the stripping partition is positioned at the lowest point of the outer feeding turntable, and the thickness of the stripping partition is less than the spacing of the annular gap.

[0013] In a preferred embodiment of the present invention, when the driving slider drives the outer feeding turntable to rise, the transmission outer teeth and the meshing rack separate from each other; when the outer feeding turntable descends, the transmission outer teeth and the meshing rack mesh with each other.

[0014] As a preferred embodiment of the present invention, the outer feeding turntable annular array has a plurality of feeding through holes for placing the adjusting bolt blanks, and the feeding through holes correspond to the magnetic attraction positions of the magnet ring.

[0015] As a preferred embodiment of the present invention, the outer feeding turntable drives the feeding side plate to slide along the transverse slide through tooth engagement, thereby enabling the feeding channel to move backward and avoid the machine tool processing station.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This device is specially designed for use with bolt processing machine tools.

[0021] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0022] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 7As shown in the figure, an automatic feeding device for a bolt processing machine tool provided by an embodiment of the present invention includes a base 1, a vertical lifting bracket 2, a drive slider 3 that can slide up and down along the vertical lifting bracket 2, a drive motor 4 mounted on the drive slider 3, a coaxial magnetic transmission assembly 5, a feeding channel assembly 6, and a stripping partition 7; the coaxial magnetic transmission assembly 5 includes a connecting plate 51 fixedly connected to the output shaft of the drive motor 4, a magnetic ring 52 fixedly disposed on the outside of the connecting plate 51, and an outer feeding turntable 53 movably sleeved outside the magnetic ring 52, the magnetic ring 52 and the outer feeding turntable 53 being connected to each other. An annular gap 54 is left between the discs 53, and a limiting engagement structure is provided between them to achieve synchronous circumferential rotation; the feeding channel assembly 6 is located above the base 1, and includes a base plate 61, a transverse slide 64 opened on the base plate 61, and two sets of feeding side plates that can slide relative to each other along the transverse slide 64. An elastic pushing structure is assembled between the two feeding side plates; the unloading partition 7 is fixedly arranged and one end extends into the annular gap 54. The outer circumference of the outer feeding turntable 53 is provided with transmission external teeth 58, and a meshing rack 66 that can cooperate with the transmission external teeth 58 is fixed on the feeding side plate. When the automatic feeding device for this adjusting bolt processing machine tool is working, the drive motor 4 drives the connecting disc 51 and the outer fixed magnetic ring 52 to rotate synchronously. The outer feeding turntable 53 rotates together with the magnetic ring 52 through the inner limiting structure engaging and linkage. The blanks for adjusting bolts to be conveyed are placed inside the through-hole of the feeding turntable and firmly attracted and fixed by the magnetic force generated by the magnetic ring 52. The blanks will not fall off during the conveying process as the turntable tilts and rotates. Only when the blanks rotate to the lowest position of the equipment, the fixedly installed unloading partition 7 extends into the annular gap 54, separating the blanks from the magnetic ring 52. After the magnetic force disappears, the blanks fall smoothly into the feeding channel below by their own weight, completing the unloading process. The operator can flexibly adjust the passage width between the two feeding side plates using the transverse slide 64 on the base plate 61. With the elastic clamping action of the spring plates at the bottom of the side plates, the feeding channel can be adapted to adjusting bolt blanks of different outer diameters. After the batch feeding operation is completed, the lifting drive 8 drives the entire feeding turntable to move downward. The outer drive gear 58 of the turntable meshes with the meshing rack 66 of the feeding side plate. The drive motor 4 reverses slightly to drive the entire feeding channel backward, actively avoiding the machine tool processing station and eliminating processing interference. When it is necessary to change the adjusting bolts of different specifications in daily production, only the limiting component at the end of the motor output shaft needs to be removed, and the outer feeding turntable 53 can be directly pulled out laterally for replacement without disassembling the internal magnetic drive structure. This allows for quick equipment specification switching and adapts to the diverse processing needs of machine tools.

[0024] The vertical lifting bracket 2 is threaded with a stud 9, and a first limiting plate 10 is fixedly connected to the stud 9. The first limiting plate 10 is attached to the outer feeding turntable 53 and one of the feeding side plates. A detachable second limiting plate 11 is installed on the other side of the base plate 61. The second limiting plate 11 is attached to the outer feeding turntable 53 and the other feeding side plate. The second limiting plate 11 axially limits the outer feeding turntable. After removing the axial end limiting piece, the outer feeding turntable 53 can be removed laterally.

[0025] The vertical lifting bracket 2 is provided with a vertical guide slide 21 on its inner side, and the drive slider 3 is slidably assembled inside the vertical guide slide 21.

[0026] It also includes a lifting drive component 8 fixedly installed on the base 1. The lifting drive component 8 is connected to the drive slider 3 to drive the drive slider 3 to complete the lifting action. The limiting engagement structure consists of a transmission limiting notch 55 opened on the outer wall of the magnet ring 52 and a transmission limiting block 56 fixed on the inner wall of the outer feeding turntable 53. The transmission limiting block 56 is engaged in the transmission limiting notch 55 to realize torque transmission.

[0027] The elastic pushing structure is an elastic pushing component 65, which is installed at the bottom of the two feeding side plates. Under normal conditions, it pushes the two sets of feeding side plates together. The stripping partition 7 is set at the lowest position of the outer feeding turntable 53, and the thickness of the stripping partition 7 is less than the spacing of the annular gap 54.

[0028] When the drive slider 3 drives the outer feeding turntable 53 to rise, the transmission external gear 58 and the meshing rack 66 separate; when the outer feeding turntable 53 descends, the transmission external gear 58 and the meshing rack 66 mesh. The outer feeding turntable 53 has a plurality of feeding through holes 57 in a circular array for placing the blanks of the adjusting bolts, and the feeding through holes 57 correspond to the magnetic attraction positions of the magnetic ring 52. The outer feeding turntable 53 drives the feed side plate to slide along the transverse slide 64 through the tooth engagement, so that the feed channel retracts and avoids the machine tool processing position.

[0029] Specifically, the device as a whole includes a base 1, a vertical lifting bracket 2, a drive slider 3, a drive motor 4, a coaxial magnetic transmission assembly 5, a feeding channel assembly 6, and a stripping partition 7.

[0030] The vertical lifting bracket 2 is vertically fixedly installed on the upper surface of the base 1. The vertical lifting bracket 2 has a vertical guide slide 21 extending in the vertical direction inside. The drive slider 3 can slide up and down inside the vertical guide slide 21. The bottom of the drive slider 3 is connected to the lifting drive component 8 fixed on the base 1. The lifting drive component 8 adopts an electric push rod, which can accurately control the lifting stroke and stopping position of the drive slider 3.

[0031] The drive motor 4 is horizontally fixedly installed on the side of the drive slider 3. The output shaft of the drive motor 4 extends horizontally forward. The coaxial magnetic transmission assembly 5 is coaxially fixedly installed at the end of the output shaft and completes the lifting and lowering action synchronously with the drive slider 3.

[0032] The coaxial magnetic drive assembly 5 is the core feeding structure, including a connecting plate 51, a magnetic ring 52, and an outer feeding turntable 53. The center hole of the connecting plate 51 is interference-fitted with the output shaft of the drive motor 4, and the connecting plate 51 rotates synchronously and continuously with the output shaft. The magnetic ring 52 is coaxially fixedly sleeved on the outer periphery of the connecting plate 51, and the two do not rotate relative to each other, but rotate synchronously.

[0033] The outer feeding turntable 53 is loosely fitted coaxially on the outer periphery of the magnet ring 52. A uniform annular gap 54 is reserved between the outer periphery of the magnet ring 52 and the inner periphery of the outer feeding turntable 53. The annular gap 54 is used to avoid the material removal partition 7.

[0034] The outer periphery of the magnet ring 52 is provided with a circumferential limiting transmission notch 55. The inner periphery of the outer feeding turntable 53 is integrally formed or fixedly installed with a transmission limiting block 56. The transmission limiting block 56 is matched and snapped into the inside of the transmission limiting notch 55 to realize circumferential limiting transmission. That is, when the magnet ring 52 rotates, it can drive the outer feeding turntable 53 to rotate synchronously, without affecting the axial disassembly of the outer feeding turntable 53.

[0035] Multiple feeding through holes 57 are evenly opened along the circumference of the outer feeding turntable 53. The size of the feeding through holes 57 matches the corresponding bolt blank. The position of the feeding through holes 57 corresponds exactly to the magnetic attraction area of ​​the magnetic ring 52. After the bolt blank enters the feeding through hole 57, it is stably attracted by the magnetic force of the magnetic ring 52 and will not fall off during the entire process of tilting and horizontal rotation of the turntable.

[0036] A stud 9 is threaded onto the vertical lifting bracket, and a first limiting plate 10 is fixedly connected to the stud 9. The first limiting plate 10 is attached to the outer feeding turntable and one of the feeding side plates. A detachable second limiting plate 11 is installed on the other side of the base plate. The second limiting plate 11 is attached to the outer feeding turntable and the other feeding side plate. The second limiting plate 11 axially limits the outer feeding turntable. After removing the axial end limiting piece, the outer feeding turntable can be removed laterally.

[0037] When it is necessary to replace the outer feeding turntable 53 of different specifications, only the second limiting plate 11 needs to be removed, and the outer feeding turntable 53 can be pulled out laterally along the output shaft axis to complete the quick change of type without disassembling the magnet ring 52 and the connecting plate 51.

[0038] The feeding channel assembly 6 is installed on the upper surface of the base 1 and located directly below the coaxial magnetic drive assembly 5, receiving the bolt blanks that fall after being unloaded. The feeding channel assembly 6 includes a base plate 61, a first feeding side plate 62, a second feeding side plate 63, a transverse slide 64, and an elastic pusher 65. The base plate 61 is slidably installed on the base 1, and the transverse slide 64 is opened horizontally on the base plate 61. The bottoms of the first feeding side plate 62 and the second feeding side plate 63 are slidably assembled on the transverse slide 64, forming a straight feeding channel between them.

[0039] The elastic pusher 65 uses spring steel spring sheets, which are installed at the bottom of the first feed side plate 62 and the second feed side plate 63 respectively. The spring sheets always apply opposing pressing forces to the two feed side plates, so that the spacing of the feed channel adapts to the outer diameter of the bolt blank. At the same time, the position of the side plates can be manually adjusted laterally to adapt to different specifications of blanks.

[0040] The stripping baffle 7 is fixed to the upper surface of the base 1. The stripping baffle 7 is made of rigid plastic and its thickness is less than the width of the annular gap 54. The front end of the stripping baffle 7 extends into the annular gap 54 and is set at the lowest rotation position corresponding to the outer feeding turntable 53. When the feeding through hole 57 drives the bolt blank to rotate to the lowest position, the stripping baffle 7 is inserted between the blank and the magnetic ring 52, completely cutting off the magnetic attraction force. The bolt blank falls accurately into the feeding channel under the action of gravity, completing the fixed-point stripping.

[0041] The outer peripheral side of the outer feeding turntable 53 is machined with external transmission teeth 58, and the outer side wall of the first feeding side plate 62 is correspondingly fixed with a meshing rack 66. When the driving slider 3 drives the coaxial magnetic transmission assembly 5 to descend, the external transmission teeth 58 and the meshing rack 66 mesh with each other; when the driving slider 3 rises, the external transmission teeth 58 and the meshing rack 66 completely disengage and do not interfere with each other.

[0042] Working principle: The complete operating procedure of this device is as follows: During the feeding stage: the drive slider 3 is in the rising position, the transmission external gear 58 disengages from the meshing rack 66, the drive motor 4 drives the coaxial magnetic transmission component 5 to rotate continuously, the bolt blank is attracted into the feeding through hole 57, and when it rotates to the lowest position with the turntable, it is demagnetized and de-discharged by the de-discharge partition 7, falling into the feeding channel and being pushed forward one by one. Avoidance processing stage: After feeding is completed, the lifting drive component 8 drives the drive slider 3 to descend, the transmission external gear 58 meshes with the meshing rack 66, the drive motor 4 reverses slightly, and drives the feeding channel assembly 6 to move backward as a whole through tooth transmission, so that the feeding channel drives the billet to avoid the processing station, the billet is positioned in the processing position, and the material channel retracts without interfering with the tool processing. Reset feeding stage: After processing is completed, drive slider 3 rises, teeth disengage, drive motor 4 rotates forward to continue feeding, and feed side plate is reset under the action of elastic pusher 65; Specification change stage: Remove the second limiting plate 11, pull out the outer feeding turntable 53 laterally, replace it with a new turntable with the corresponding hole diameter and hole spacing, and reinstall the limiting parts to complete the change. At the same time, the spacing of the feeding side plate can be adjusted laterally to adapt to the new specification billet.
