Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of thread rolling machines, and more specifically, to a fully automatic thread rolling machine for fabricating circuit components. Background Technology

[0002] In the manufacturing process of power line components, thread rolling machines are the core equipment for shaping threads on critical components such as bolts and nuts. The efficiency of their automated feeding and unloading has a decisive impact on overall production efficiency and cost control. However, traditional thread rolling machines for power line component manufacturing have significant shortcomings in automation, especially in the feeding and unloading stages, which are heavily reliant on manual operation. This greatly reduces the continuity of production, making it difficult to improve efficiency and meet the urgent needs of today's large-scale production.

[0003] Most common thread rolling machines employ a manual loading and unloading operation mode. Operators need to manually and precisely place the blank to be processed at the thread rolling station, and then manually remove the finished product after processing. This process is not only cumbersome, but also time-consuming for each loading and unloading operation.

[0004] Moreover, traditional thread rolling machines generally lack the function of automatic collection of finished products. Finished components fall randomly around the equipment, making the work area messy and requiring dedicated personnel to clean and collect them. This undoubtedly increases labor costs, and the disorderly accumulation of components may also cause equipment failure, further reducing production efficiency.

[0005] With the accelerated development of smart grid construction, the demand for power line components is becoming increasingly diversified and large-scale. The traditional thread rolling machine, with its heavy reliance on manual labor, low changeover efficiency, and poor production continuity, has become a stumbling block to the industry's progress towards high efficiency. Currently, there is an urgent need to develop a new type of thread rolling machine with adaptive feeding capabilities, fully automated unloading, and compatibility with processing components of various specifications. This would overcome the technical challenges of "heavy reliance on manual labor, slow changeover speed, and low production efficiency," and propel power line component manufacturing towards intelligent and efficient processes. Utility Model Content

[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide a fully automatic thread rolling machine for the preparation of circuit components, which solves the technical problem that existing thread rolling machines generally lack the function of automatic collection of finished products, and the processed components will fall randomly around the equipment, which not only makes the work area messy, but also requires special personnel to clean and collect them.

[0007] According to one aspect, at least one embodiment of this disclosure provides a fully automatic thread rolling machine for fabricating circuit components, comprising:

[0008] A platform and a pair of uprights, the uprights being fixed to the platform;

[0009] A thread rolling assembly, wherein the thread rolling assembly is disposed on the upright plate;

[0010] A support base and a feeding assembly, wherein the support base is disposed on the frame and the feeding assembly is disposed outside the frame;

[0011] A feeding assembly is disposed between the support base and the platform;

[0012] The feeding assembly includes a pair of telescopic cylinders, both of which are fixed to the bottom of the frame. A roller frame is provided at the output end of the telescopic cylinder. Notches are provided on both sides of the roller frame. An outer frame is provided on the side surface of the frame. A drive screw is provided inside the top of the outer frame. A push rod is connected to the drive screw by a threaded connection.

[0013] As a further technical solution, the notch, the support base, and the push rod are located in the same straight line position, and an extension frame is provided at one end of the outer frame, with a stabilizing rod rotatably connected to the lower end of the extension frame.

[0014] As a further technical solution, the feeding assembly includes a bottom opening, which is formed on the surface of the frame. The support base is rotatably connected to the bottom opening via a rotating shaft, and a pair of fixing rods are provided at the bottom of the frame.

[0015] As a further technical solution, a second cylinder is rotatably connected between the fixed rods via a pin, a connecting groove is provided at the bottom of the support base, the output end of the second cylinder is rotatably connected in the connecting groove via a pin, and a conveyor is provided at one end of the bottom of the platform.

[0016] As a further technical solution, the thread rolling assembly includes a pair of hydraulic cylinders, both of which are fixed to the side surface of the vertical plate. A connecting frame is provided at the output end of the hydraulic cylinder, and a thread forming roller is installed inside the connecting frame. The thread forming roller is rotated by a motor.

[0017] As a further technical solution, the bottom surface of the roller frame is inclined, and the lowest point of the roller frame is an arc-shaped concave structure.

[0018] As a further technical solution, the surface of the power wheel of the conveyor is concave, and the conveyor belt of the conveyor is attached to the surface of the power wheel at the same curvature.

[0019] As a further technical solution, the support base can be rotated downwards by 30° by a second cylinder.

[0020] The beneficial effects of the embodiments disclosed herein are as follows:

[0021] 1. In this disclosure, the feeding assembly adjusts the height of the rolling frame via a telescopic cylinder. The inclined bottom surface of the rolling frame allows the workpiece to automatically roll to the notch. The drive screw drives the push rod to precisely push the workpiece to the support seat, realizing automatic feeding of the workpiece and avoiding the tedious operation of manual feeding. The extension frame and stabilizing rod assist in supporting the workpiece and prevent tilting during thread rolling. This assembly can continuously convey workpieces, improve feeding efficiency and stability, and solve the problems of time-consuming, labor-intensive, and unreliable manual feeding in traditional equipment. It automates the feeding process of the thread rolling machine, reduces labor costs, and improves production efficiency.

[0022] 2. In this disclosure, the unloading component drives the support base to rotate via the second cylinder, and uses gravity to make the processed workpiece slide down to the conveyor, realizing automatic unloading of finished products without manual removal, avoiding workpieces falling randomly. The conveyor receives the workpieces and transports them to the collection area, ensuring the cleanliness of the work area and reducing the labor cost of dedicated cleaning. This component is linked with the feeding and thread rolling components to form an automated production process, solving the problem of low efficiency and reliance on manual unloading in traditional equipment, improving the automation level and production continuity of the thread rolling machine, and making the preparation of circuit components more efficient.

[0035] like Figures 1-4 As shown, it illustrates a fully automatic thread rolling machine for fabricating circuit components according to an embodiment of the present disclosure, comprising:

[0036] A platform 1 and a pair of upright plates 2, wherein the upright plates 2 are fixed on the platform 1;

[0037] Thread rolling assembly 6 is disposed on the vertical plate 2;

[0038] The support base 3 and the feeding assembly 4 are provided. The support base 3 is disposed on the frame 1 and the feeding assembly 4 is disposed outside the frame 1.

[0039] The feeding assembly 5 is disposed between the support base 3 and the frame 1;

[0040] The feeding assembly 4 includes a pair of telescopic cylinders 4-1, both of which are fixed to the bottom of the frame 1. A roller frame 4-2 is provided at the output end of the telescopic cylinder 4-1. A notch 4-3 is provided on both sides of the roller frame 4-2. An outer frame 4-4 is provided on the side surface of the frame 1. A drive screw 4-5 is provided inside the top of the outer frame 4-4. A push rod 4-6 is connected to the drive screw 4-5 by a threaded connection. The notch 4-3, the support base 3, and the push rod 4-6 are located in the same straight line. An extension frame 4-7 is provided at one end of the outer frame 4-4. A stabilizing rod 4-8 is rotatably connected to the lower end of the extension frame 4-7.

[0041] In some examples, a feeding assembly 4 is designed to achieve continuous conveying of workpieces to support base 3. This assembly uses a pair of telescopic cylinders 4-1 fixed to the bottom of the frame 1 as a power source. The output end of the cylinder is connected to a roller frame 4-2, which can be raised and lowered vertically. The two side notches 4-3 are used to accommodate the workpieces to be processed. The top drive screw 4-5 of the outer frame 4-4 on the side surface of the frame 1 is controlled by a motor to rotate. The push rod 4-6, which is threaded with the screw, can move horizontally along the outer frame 4-4. The workpiece rolls on the surface of the roller frame 4-2 to the bottom, so that the notch 4-3, support base 3, and push rod 4-6 are in the same straight line. At this time, the drive screw 4-5 rotates, and the push rod 4-6 accurately pushes the workpiece in the notch 4-3 onto the support base 3, completing one feeding action. When the push rod 4-6 retracts, the height of the roller frame 4-2 can be lowered. The stabilizing rod 4-8 rotatably connected to the lower end of the extension frame 4-7 is used to fit against the top of the workpiece to prevent tilting or falling during the thread rolling process.

[0042] Through the lifting and lowering of the telescopic cylinder 4-1, the horizontal pushing of the drive screw 4-5, and the auxiliary support of the stabilizing rod 4-8, the feeding assembly 4 realizes the automated and continuous feeding of the workpiece to the support seat 3, ensuring the efficient operation of the thread rolling machine.

[0043] like Figures 1-4As shown in the figure, the feeding assembly 5 in this embodiment includes a bottom opening 5-1, which is formed on the surface of the frame 1. The support base 3 is rotatably connected to the bottom opening 5-1 via a rotating shaft. A pair of fixing rods 5-2 are provided at the bottom of the frame 1. A second cylinder 5-3 is rotatably connected between the fixing rods 5-2 via a pin. A connecting groove 5-4 is provided at the bottom of the support base 3. The output end of the second cylinder 5-3 is rotatably connected to the connecting groove 5-4 via a pin. A conveyor 5-5 is provided at one end of the bottom of the frame 1.

[0044] In some examples, to achieve rapid discharge of the workpiece after thread rolling, a feeding assembly 5 is designed. A bottom opening 5-1 is opened on the surface of the frame 1. The support base 3 is rotatably connected to the bottom opening 5-1 via a rotating shaft, allowing it to rotate within a certain angle range. A second cylinder 5-3 at the bottom of the frame 1 is hinged to a fixed rod 5-2 and a connecting groove 5-4 at the bottom of the support base 3 via pins at both ends. When the cylinder extends or retracts, it pushes and pulls the support base 3 downwards, allowing the thread-rolled workpiece to be placed on the support base 3. The second cylinder 5-3 then retracts, causing the workpiece to slide down the support base 3 under gravity and fall through the bottom opening 5-1 onto the conveyor belt of the lower conveyor 5-5. The conveyor 5-5 then transports the workpiece to a designated collection area. This design utilizes cylinder drive and gravity to achieve automatic workpiece discharge, avoiding the tediousness and safety hazards of manual material handling, and improving the automation level and production efficiency of the thread rolling machine.

[0045] like Figures 1-4 As shown in the figure, the thread rolling assembly 6 in this embodiment includes a pair of hydraulic cylinders 6-1. The hydraulic cylinders 6-1 are fixed on the side surface of the vertical plate 2. The output end of the hydraulic cylinders 6-1 is provided with a connecting frame 6-2. A thread forming roller 6-3 is installed in the connecting frame 6-2. The thread forming roller 6-3 is rotated by a motor.

[0046] In some examples, a thread rolling assembly 6 is designed to achieve precise machining of threads on the workpiece surface. A pair of hydraulic cylinders 6-1 fixed to the side surface of the vertical plate 2 provide power for thread rolling. The connecting frame 6-2 connected to its output end can move in the vertical direction to adjust the position of the thread forming roller 6-3. The thread forming roller 6-3 installed in the connecting frame 6-2 is driven to rotate by a high-precision motor. The roller surface is designed with corresponding tooth grooves according to the required thread specifications. During machining, the hydraulic cylinder 6-1 pushes the connecting frame 6-2 to move, so that the thread forming roller 6-3 contacts the workpiece on the support 3. Driven by the motor, the thread forming roller 6-3 rotates at high speed and applies pressure to the workpiece surface, forming threads on the workpiece surface through rolling plastic deformation.

[0047] Through the precise control of the rolling pressure and position by the hydraulic cylinder 6-1, and the stable adjustment of the rotation speed of the thread forming roller 6-3 by the motor, the thread rolling assembly 6 can efficiently and accurately complete the thread rolling process of the workpiece, ensuring the dimensional accuracy and surface quality of the thread.

[0048] For example, such as Figure 1 As shown, the bottom surface of the roller frame 4-2 is inclined, and the lowest point of the roller frame 4-2 is an arc-shaped concave structure.

[0049] In some examples, the inclined structure allows multiple raw materials to roll downwards naturally for continuous feeding, and the concave structure prevents them from falling off.

[0050] For example, such as Figure 3 As shown, the surface of the power wheel of the conveyor 5-5 is concave, and the conveyor belt of the conveyor 5-5 is attached to the surface of the power wheel at the same curvature.

[0051] In some examples, the concave structure allows the falling forming screw to remain inside the conveyor 5-5, preventing it from rolling off to the sides.

[0052] For example, such as Figure 2 As shown, the support base 3 can be rotated downwards by 30° by the second cylinder 5-3.

[0053] In some examples, rotating the screw downwards by 30° ensures that it can slide down unimpeded into conveyor 5-5.

[0054] In actual use: The platform 1 is fixed to the work site. The upright plate 2 is installed on the platform 1. The hydraulic cylinder 6-1 of the thread rolling assembly 6 is fixed to the side surface of the upright plate 2. The connecting frame 6-2 and the thread forming roller 6-3 are installed at the output end of the hydraulic cylinder 6-1. The telescopic cylinder 4-1 of the feeding assembly 4 is fixed to the bottom of the platform 1. The rolling frame 4-2 is installed at the output end of the telescopic cylinder 4-1, with the notch 4-3 facing the support base 3. The outer frame 4-4 is fixed to the side surface of the platform 1. The drive screw 4-5 and the push rod 4-6 are installed on the outer frame 4-4. The extension frame 4-7 and the stabilizing rod 4-8 are installed at one end of the outer frame 4-4. The unloading assembly... The bottom opening 5-1 of part 5 is opened on the surface of the frame 1. The support base 3 is connected to the bottom opening 5-1 through a rotating shaft. The fixing rod 5-2 and the second cylinder 5-3 are installed at the bottom of the frame 1. The conveyor 5-5 is installed at one end of the bottom of the frame 1. The workpiece to be processed is placed on the rolling rack 4-2. The telescopic cylinder 4-1 adjusts the height of the rolling rack 4-2. The drive screw 4-5 drives the push rod 4-6 to push the workpiece to the support base 3. The hydraulic cylinder 6-1 pushes the thread forming roller 6-3 to roll the workpiece. After processing, the second cylinder 5-3 drives the support base 3 to rotate. The workpiece slides into the conveyor 5-5 and is then conveyed outward.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
