Description

Technical Field

[0001] The present application relates to the field of mechanical processing technology, and in particular to a processing device for a self-drilling screw sleeve. Background Art

[0002] As a common fastener, self-drilling screw inserts are widely used in mechanical manufacturing and assembly industries. With the continuous improvement of industrial automation, the demand for efficient and precise processing of self-drilling screw inserts is growing. Existing self-drilling screw insert processing equipment is mostly completed manually or semi-automatically, which is not only inefficient, but also prone to human errors, affecting product quality.

[0003] At present, there are two main methods for processing self-drilling screw inserts: one is the traditional manual operation, where workers use tools to perform drilling, countersinking, tapping and other processes one by one; the other is the semi-automatic production line, which, although some mechanical equipment has been introduced, still requires manual intervention to complete key steps. These methods have improved work efficiency to a certain extent, but there are still deficiencies in continuity and precision.

[0004] However, the main problems of the above traditional methods are: manual operation has high labor intensity, low production efficiency, and is easily affected by human factors, resulting in unstable quality; and although the semi-automatic production line has improved, it still relies on manual intervention and cannot achieve full automation, thus limiting the improvement of overall production efficiency and product quality. Therefore, there is an urgent need for a device that can realize fully automated processing of self-drilling screw inserts to overcome the shortcomings of the existing technology. Summary of the invention

[0005] In order to improve the problem that existing self-drilling screw insert processing equipment mostly relies on manual operation or semi-automatic production lines, has low production efficiency and poor product consistency, the present application provides a processing equipment for self-drilling screw inserts.

[0006] The present application provides a processing device for a self-drilling screw sleeve adopts the following technical solution: A processing device for self-drilling screw sleeves comprises a workbench, on which a transmission track is inclined, a lifting mechanism is arranged on the output end of the transmission track, a blocking mechanism for automatically intercepting the screw sleeve is arranged between the lifting mechanism and the transmission track, a boosting mechanism is arranged perpendicular to the transmission direction of the transmission track, a limit seat is arranged along the pushing direction of the boosting mechanism, a driving mechanism for driving it to rotate and clamp the screw sleeve is also arranged on the limit seat, and drilling mechanisms for drilling the screw sleeve are arranged on both sides of the limit seat.

[0007] By adopting the above technical solution, the screw sleeve rolls from the input end of the transmission track to the output end along the inclined tabletop under the action of gravity. The lifting mechanism on the output end of the transmission track lifts a single falling screw sleeve, and the end face of the lifting structure is adapted to the shape and structure of the screw sleeve. The blocking mechanism intercepts and releases each screw sleeve separately, preventing multiple screw sleeves from entering the processing area simultaneously, improving the processing accuracy. The boosting mechanism pushes the screw sleeve along its axial direction, enabling the screw sleeve to enter the limit seat. The driving mechanism clamps the screw sleeve in the limit seat, and the drilling mechanisms on both sides drill the screw sleeve synchronously. Then, the driving mechanism drives the screw sleeve to rotate 120 degrees, and the single-side drilling mechanism performs the drilling operation again. After the operation is completed, the screw sleeve is dropped to one side. Through such repeated operations of transmission, pushing, and drilling, the automation of the screw sleeve is realized, reducing manual intervention, improving the processing efficiency, and enabling the self-tapping screw sleeve to complete the processing operation automatically and efficiently.

[0008] Optionally, the lifting mechanism includes a telescopic cylinder installed on the workbench. A placing block that moves along its axial direction is further connected to the output end of the telescopic cylinder. The cross-section of the placing block is arched.

[0009] By adopting the above technical solution, when the screw sleeve rolls onto the placing block, the output end of the telescopic cylinder lifts the placing block upward. The placing block with an arched cross-section facilitates the limit and support of the screw sleeve. The telescopic cylinder precisely controls the rising and falling actions of the placing block, thereby realizing the precise positioning of the screw sleeve. Its arched shape makes the screw sleeve more fitting and stable when being lifted, avoiding problems such as sliding or offset caused by planar contact, improving the processing accuracy and efficiency. At the same time, the structure is simple and reliable, facilitating maintenance and adjustment.

[0010] Optionally, the boosting mechanism includes a mounting bracket installed on the workbench and a stroke cylinder arranged on the mounting bracket. A push head is further arranged on the output end of the stroke cylinder. The diameter of the push head is equal to the outer diameter of the screw sleeve.

[0011] By adopting the above technical solution, the function of precisely pushing the screw sleeve is realized. The mounting bracket is fixed on the workbench, ensuring the stable operation of the stroke cylinder. The output end of the stroke cylinder is connected with a push head, and the matching of the push head with the outer diameter of the screw sleeve enables the push head to accurately contact and push the screw sleeve during the pushing process, avoiding situations such as pushing failure or damage to the screw sleeve caused by size mismatch. This not only improves the processing efficiency but also ensures the product quality.

[0012] Optionally, the driving mechanism includes a rotating disk rotatably arranged on the limit seat. A toothed ring is arranged on the rotating disk, and a toothed plate is meshed with the toothed ring. One end of the toothed plate is installed with a piston cylinder. The limit seat is provided with a channel for the screw sleeve to pass through, and a contact member is arranged along the radial direction of the screw sleeve in the channel. A control pump is arranged on the workbench, and the control pump and the contact member are connected through an air pipe.

[0013] By adopting the above technical solution, precise positioning and stable clamping of the screw sleeve are achieved. The driving mechanism enables the rotating disk and the gear ring to accurately control the rotation angle, ensuring the stability of the screw sleeve during the machining process. The combined use of the toothed plate and the piston cylinder realizes rapid response and accurate positioning, improving production efficiency. The channel on the limit seat facilitates the entry and exit of the screw sleeve, while ensuring the position accuracy of the screw sleeve. The combined use of the abutting member and the control pump can quickly clamp the screw sleeve when it enters the channel, preventing loosening or offset during the machining process, thereby improving the machining quality and the finished product rate.

[0014] Optionally, the drilling mechanism includes mounting brackets installed on both sides of the limit seat, a driving motor provided on the mounting brackets, and a pushing cylinder provided on one side of the mounting brackets. A through groove is formed in the mounting brackets. A limit frame slidably connected to the pushing cylinder is provided in the through groove. A drilling machine is connected to the limit frame. The driving motor is connected to the drilling machine. Adjacent drilling machines are arranged at an obtuse angle.

[0015] By adopting the above technical solution, the drilling mechanism can achieve precise positioning and efficient drilling. The driving motor and the pushing cylinder on the mounting brackets cooperate to ensure that the drilling machine can perform drilling operations at precise positions; the pushing cylinder drives the limit frame to slide in the through groove, enabling the drilling machine to flexibly adjust its position to realize the drilling operation on the screw sleeve. The drilling machine is connected to the driving motor, ensuring the power stability and accuracy during the drilling process. The adjacent drilling machines are arranged at an obtuse angle, which helps to improve the drilling efficiency and reduce interference, ensuring the coordination during multi-point simultaneous drilling.

[0016] Optionally, a chip cleaning mechanism is further provided on one side of the mounting brackets. The chip cleaning mechanism includes an air pump installed on the workbench, a processing pipe with a cavity formed inside installed on the mounting brackets. The processing pipe and the air pump are connected through an air pipe. An air outlet is provided on one side of the processing pipe facing the processed screw sleeve.

[0017] By adopting the above technical solution, the chip cleaning mechanism effectively removes the chips generated during the drilling process, preventing the chips from affecting the subsequent machining accuracy and quality; the air pump is connected to the processing pipe through the air pipe, which can generate high-pressure gas and spray it out from the air outlet of the processing pipe to blow the metal chips generated during drilling away from the processing area, keeping the surface of the workpiece clean, improving the machining quality and efficiency of the screw sleeve, and at the same time, the structure is simple and convenient for maintenance and operation.

[0018] Optionally, the abutting member includes a suction pump installed on the workbench and a pressing block slidably arranged radially in the channel. A bladder chamber is provided in the middle of the pressing block. The bladder chamber and the suction pump are connected through an air pipe. The abutting block slides in a receiving groove formed in the channel.

[0019] By adopting the above technical solution, precise positioning and stable clamping of the bushing are achieved. The air path connection between the suction pump and the bladder chamber enables the pressing block to expand rapidly when needed, thus closely fitting the outer wall of the bushing, ensuring that the bushing will not shift or loosen during the processing. After the bushing is fixed in the channel, the drilling mechanism can accurately drill it, improving the processing accuracy and efficiency. The accommodating groove ensures the stability of the pressing block during the sliding process, avoiding deviation caused by vibration or other external factors, and further enhancing the clamping effect.

[0020] Optionally, the blocking mechanism includes a blocking plate installed at the output end of the transmission track. A spring rod for driving the blocking plate to lift and lower is installed at the bottom of the blocking plate. The blocking plate and the placing block are connected by a connecting rod, and the connecting rod and the limit seat are rotationally matched through a rotating shaft.

[0021] By adopting the above technical solution, the blocking mechanism effectively intercepts the bushings on the transmission track, preventing multiple bushings from entering the processing area simultaneously. When the placing block of the lifting mechanism rises, the connecting rod drives the blocking plate to descend, thereby allowing a single bushing to enter the processing position. The spring rod enables the blocking plate to have a certain elasticity and can quickly reset after the bushing passes through, ensuring that only one bushing is sent into the processing area each time, improving the processing efficiency and accuracy, and avoiding processing failures caused by multiple bushings entering simultaneously.

[0022] Optionally, threads are provided on the surface of the pressing block on the side close to the bushing.

[0023] By adopting the above technical solution, the threads provided on the surface of the pressing block can increase the friction with the bushing, ensuring that the bushing will not loosen or shift during the drilling process, thereby improving the processing accuracy and stability.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. By providing an inclined transmission track and a lifting mechanism, the bushing can be automatically positioned and lifted when entering the processing position, ensuring the accuracy of subsequent processes such as drilling and countersinking, and effectively improving the processing quality and efficiency; 2. The interlocking cooperation between the blocking mechanism and the lifting mechanism enables only one bushing to be sent into the processing area each time, avoiding problems such as blockage or misalignment caused by multiple bushings entering simultaneously, and ensuring the stability and reliability of the equipment operation; 3. The synergistic effect of the boosting mechanism and the limit seat keeps the bushing in a stable posture during the propulsion process, and cooperates with the driving mechanism to achieve rapid clamping and rotation of the bushing, further improving the processing speed and accuracy.

[0036] Refer to Figure 1, including a workbench 1, on which a transmission track 2 is inclined. The transmission track 2 with an inclined angle makes it easy for the screw sleeve to roll and unload along its end surface due to its own gravity. A lifting mechanism 3 is arranged on the output end of the transmission track 2, and a blocking mechanism 9 for automatically intercepting the screw sleeve is also arranged between the lifting mechanism 3 and the transmission track 2. A boosting mechanism 4 is arranged perpendicular to the transmission direction of the transmission track 2, and a limit seat 5 is arranged along the moving direction of the boosting mechanism 4.

For example, the telescopic cylinder 31 can be a cylinder with high response speed and stability. In addition, an electric push rod can be selected as an alternative, which can also achieve fast and accurate lifting action. The shelf block 32 is in an arched shape to better adapt to screw sleeves of different diameters and reduce the occurrence of jamming.

[0038] See also Figure 1 As shown, the boost mechanism 4 includes a mounting frame 41 mounted on the workbench 1 and a stroke cylinder 42 arranged on the mounting frame 41, and a push head 43 is also arranged on the output end of the stroke cylinder 42, and the diameter of the push head 43 is equal to the outer diameter of the screw sleeve. For example, the stroke cylinder 42 can select a standard cylinder, and the push head 43 can be customized according to the screw sleeve specifications actually produced. In addition, a hydraulic cylinder can also be selected as an alternative, which can adjust the thrust size in a larger range and is suitable for screw sleeves of different weights.

[0039] See also Figure 5 As shown, the driving mechanism 6 includes a rotating disk 61 rotatably arranged on the limit seat 5, a gear ring 62 is fixedly arranged on the rotating disk 61, a tooth plate 63 is meshed on the gear ring 62, and a piston cylinder 64 is installed at one end of the tooth plate 63. With the push of the piston cylinder 64, the tooth plate 63 moves on the workbench 1, thereby driving the meshing gear ring 62 and the rotating disk 61 to rotate together, so as to realize the drilling of different angles of the screw sleeve, the limit seat 5 is provided with a channel for the screw sleeve to pass through, and an abutment 65 is arranged in the channel along the radial direction of the screw sleeve, and a control pump 66 is arranged on the workbench 1, and the control pump 66 and the abutment 65 are connected through an air pipe. For example, the piston cylinder 64 can select a cylinder with high sensitivity and reliability. In addition, a solenoid valve can be selected as an alternative to more accurately control the direction and flow of the airflow.

[0040] See also Figure 3 , Figure 4 andFigure 7 As shown, the abutting member 65 includes a suction pump 651 installed on the workbench 1 and a pressing block 652 slidably arranged radially in the channel. Threads are provided on the surface of one side of the pressing block 652 that abuts against the screw sleeve, increasing the friction with the screw sleeve to ensure that the screw sleeve does not loosen or shift during the drilling process, improving the machining accuracy and stability; a bladder chamber 653 is provided in the middle of the pressing block 652, and the bladder chamber 653 and the suction pump 651 are connected by an air pipe. The abutting block slides in a receiving groove 654 opened in the channel, and the receiving groove 654 ensures the sliding stability of the pressing block 652, avoiding deviation caused by vibration or other factors and enhancing the clamping effect; when the suction pump 651 inflates the bladder chamber 653, the pressing block 652 can expand quickly, and the pressing block 652 fits against the outer wall of the screw sleeve, ensuring that the screw sleeve does not displace or loosen during the machining process. The screw sleeve is confined in the channel, and the drilling mechanism 7 can perform precise drilling operations at different angles on it, improving the machining accuracy and efficiency.

[0041] See Figure 2 As shown, the drilling mechanism 7 includes mounting brackets 71 installed on both sides of the limit seat 5, a driving motor 72 arranged on the mounting brackets 71, and a pushing cylinder 73 arranged on one side of the mounting brackets 71. Through grooves are opened in the mounting brackets 71, and a limit frame 74 slidably connected to the pushing cylinder 73 in the through grooves is connected to the pushing cylinder 73. A drilling machine 75 is connected to the limit frame 74, and the driving motor 72 is connected to the drilling machine 75. Adjacent drilling machines 75 are arranged at an obtuse angle. For example, the driving motor 72 can be an AC motor with moderate power and stable operation, and the pushing cylinder 73 can be a cylinder with rapid response and precise positioning. The pushing cylinder 73 pushes the limit frame 74 to slide in the through groove, enabling the drilling machine 75 to adjust its position along its axis. An expansion sleeve rod is provided at the end of the drilling machine 75 away from the screw sleeve machining. The inner rod ends of the expansion sleeve rod are respectively connected to the driving motor 72 and the drilling machine 75, and the outer rod of the expansion sleeve rod is connected to the limit frame 74. (The inner rod and outer rod of the expansion sleeve rod are not shown). The driving motor 72 drives the expansion sleeve rod and the drilling machine 75 to rotate, enabling the drilling machine 75 to perform drilling operations on the surface of the screw sleeve.

[0042] See Figure 2 As shown, a chip cleaning mechanism 8 is also provided on one side of the mounting bracket 71. The chip cleaning mechanism 8 includes an air pump 81 installed on the workbench 1, and a processing pipe 82 with a cavity inside is installed on the mounting bracket 71. The processing pipe 82 and the air pump 81 are connected by an air pipe. An air outlet is provided on the side of the processing pipe 82 facing the processed screw sleeve. The air pump 81 conveys pressurized air through the air pipe to generate high-pressure gas, enabling the air outlet of the processing pipe 82 to blow chips on the processed surface of the screw sleeve, blowing the metal chips generated during drilling away from the processing area in a timely manner, maintaining the cleanliness of the screw sleeve surface, and improving the processing quality and efficiency of the screw sleeve.

[0043] SeeFigure 6 As shown in the figure, the blocking mechanism 9 includes a blocking plate 91 installed at the output end of the transmission track 2. A spring rod 92 for driving the blocking plate 91 to lift and lower is installed at the bottom of the blocking plate 91. The blocking plate 91 and the placing block 32 are connected by a connecting rod. The connecting rod and the limit seat 5 are rotationally matched through a rotating shaft. The structure of the spring rod 92 is as shown in the figure. When the placing block 32 is lifted by the telescopic cylinder 31, the rotating shaft on the connecting rod serves as the central fulcrum. Due to the end face height of the placing plate at the output end of the transmission track 2, only a single screw sleeve can be placed on the placing block 32. When the telescopic cylinder 31 retracts and resets, the blocking plate 91 blocks and intercepts the screw sleeve that rolls down alone. The height of the placing block 32 is lower than the output end height of the transmission track 2, so it can be smoothly placed on the end face of the placing block 32. Cooperating with the spring rod 92, the blocking plate 91 can reciprocate in the vertical direction, thereby improving the precision and efficiency of the technician and avoiding processing failures caused by multiple screw sleeves entering simultaneously.

[0044] The implementation principle of a processing device for self-tapping screw sleeves in an embodiment of this application is as follows: The screw sleeve is lifted from the transmission track 2 by the lifting mechanism 3, then pushed to the limit seat 5 by the boosting mechanism 4, and then the driving mechanism 6 is used to fix the screw sleeve and drive it to rotate. Finally, the drilling mechanism 7 completes the drilling operation of the screw sleeve. During the whole process, each component works together to realize the fully automated processing of self-tapping screw sleeves. Compared with traditional manual operation or semi-automatic production lines, the device for self-tapping screw sleeves greatly improves production efficiency and product consistency and reduces the influence of human errors.
