Description

Technical Field

[0001] The utility model relates to the field of drilling equipment, in particular to a multi-station component drilling equipment with automatic feeding. Background Art

[0002] Component drilling equipment is a mechanical device used for processing holes in mechanical components. Among them, the vertical drilling machine is one type of component drilling equipment, whose main shaft is vertically arranged and the center position is fixed. It is widely used in machinery manufacturing and repair factories, mainly for processing holes of medium and small-sized workpieces.

[0003] Component drilling is an essential and important link in the field of metal processing. Especially when dealing with cylindrical metal workpieces, the drilling accuracy and efficiency are directly related to the product quality and the overall efficiency of the production line. Traditional component drilling equipment is often limited to single-station operation, that is, it can only drill a single workpiece each time. This not only limits the production efficiency but also increases the frequency and complexity of manual intervention.

[0004] To overcome this limitation, multi-station rotary drilling equipment has emerged. By setting multiple stations on the turntable, this equipment can accommodate and process multiple cylindrical metal workpieces simultaneously, significantly improving the drilling continuity and production efficiency.

[0005] When the existing multi-station rotary drilling equipment performs automatic feeding, it often lacks an effective workpiece fixing mechanism. When the workpiece is placed on the station of the turntable, due to mechanical vibration, transmission error, or the irregularity of the workpiece's own shape, it is very difficult to ensure that each workpiece can be accurately and stably positioned at the predetermined position. This uncertainty in position can easily lead to relative deviation between the drill bit and the workpiece during the drilling process, affecting the drilling accuracy and consistency, and even possibly damaging the workpiece or the equipment. Summary of the Utility Model

[0006] To solve the problems raised above, the utility model is realized through the following technical solutions:

[0007] An automatic feeding multi-station component drilling device, comprising: a support frame; a drilling machine installed on the support frame for drilling workpieces; a feeding tray installed on the support frame and configured to rotate on the support frame for automatically feeding the drilling machine. Through the rotating design, the automatic feeding function of the workpieces is realized, reducing the cumbersome manual feeding and time costs; a plurality of loading grooves are opened at the top of the feeding tray and are distributed in a circumferential array. The loading grooves are used to place the workpieces and serve as a platform for placing the workpieces. The design of the loading grooves facilitates the quick positioning and fixing of the workpieces; the feeding tray includes a plurality of first clamping rods and a plurality of second clamping rods. The first clamping rods penetrate the inner wall of the loading groove and extend to the outside of the feeding tray. The second clamping rods penetrate the inner wall of the loading groove. The second clamping rods and the first clamping rods are symmetrically arranged to fix the position of the workpiece in the loading groove. The first clamping rods and the second clamping rods are configured to rotate with the feeding tray. When moving to directly below the drilling machine, they move closer to each other and clamp and fix the workpiece.

[0008] It further includes: an inner seat installed on the support frame and arranged inside the inner circle of the feeding tray.

[0009] The inner seat includes: a first raised block installed on the outer circle of the inner seat. When the second clamping rod rotates with the feeding tray and passes through the first raised block, the first raised block presses the second clamping rod, causing the second clamping rod to move closer to the center of the loading groove, simplifying the clamping mechanism, reducing the complexity and failure rate of mechanical components, and at the same time improving the accuracy and reliability of clamping.

[0010] It further includes: an outer seat installed on the support frame and arranged outside the outer circle of the feeding tray.

[0011] The outer seat includes: a second raised block installed on the inner circle of the outer seat. When the first clamping rod rotates with the feeding tray and passes through the second raised block, the second raised block presses the first clamping rod, causing the first clamping rod to move closer to the center of the loading groove.

[0012] The feeding tray further includes: a moving plate connected inside the loading groove and configured to move inside the loading groove for ejecting the drilled workpiece out of the loading groove. The moving design of the moving plate inside the loading groove, combined with the principle of like poles repelling each other of the magnetic attracting members, realizes the automatic ejection function of the drilled workpiece.

[0013] The feeding tray further includes: a second magnetic attracting member, one end of which is connected to the bottom of the moving plate, and the other end penetrates the bottom wall of the loading groove and extends to the outside of the feeding tray. A first magnetic attracting member is connected to the support frame and configured to repel the second magnetic attracting member with the same pole for providing moving power for the second magnetic attracting member.

[0014] The support frame includes: a power source installed on the support frame; a first gear installed on the power shaft of the power source, and a second gear is installed on the loading tray and connected to the first gear.

[0015] The utility model provides a multi-station component drilling device with automatic feeding. Compared with the prior art, it has the following beneficial effects:

[0016] 1. By arranging a first clamping rod and a second clamping rod on the loading tray, these clamping rods can automatically approach and clamp the workpiece when the workpiece moves to directly below the drilling machine, so that each workpiece can be firmly fixed at a predetermined position before drilling, effectively solving the positioning problems caused by mechanical vibration, transmission error or irregular workpiece shape, and significantly improving the accuracy and stability of workpiece positioning.

[0017] 2. By using the raised blocks on the inner seat and the outer seat to drive the automatic movement of the clamping rod, the design of the clamping mechanism is simplified. The non-mechanical transmission method reduces the number and complexity of mechanical components, reduces the failure rate, and at the same time facilitates the maintenance and repair of the equipment, helping to reduce the maintenance cost and improve the reliability of the equipment.

[0030] The following illustrates the implementation manners of the present utility model through specific specific examples. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific implementation manners.

[0031] Refer to Figures 1-5, A multi-station component drilling device with automatic feeding, comprising: a support frame 1; a drilling machine 2, installed on the support frame 1 for drilling workpieces; a feeding tray 3, installed on the support frame 1 and configured to rotate on the support frame 1 for automatically feeding the drilling machine 2. Through the rotational design, the feeding tray 3 realizes the automatic feeding function of workpieces, reducing the tediousness and time cost of manual feeding. The loading grooves 301 on the feeding tray 3 are circumferentially arrayed, improving the space utilization rate, enabling multiple workpieces to be prepared for feeding simultaneously, and enhancing the production efficiency; several loading grooves 301 are opened at the top of the feeding tray 3 and are circumferentially arrayed. The loading grooves 301 are used to place workpieces and serve as platforms for placing workpieces. The design of the loading grooves 301 facilitates the rapid positioning and fixing of workpieces. Its structure is compact, effectively preventing the shaking and falling off of workpieces during transportation and processing, ensuring the machining accuracy and safety; the feeding tray 3 includes several first clamping rods 302 and several second clamping rods 303. The first clamping rods 302 penetrate the inner wall of the loading groove 301 and extend to the outside of the feeding tray 3. The second clamping rods 303 penetrate the inner wall of the loading groove 301. The second clamping rods 303 and the first clamping rods 302 are symmetrically arranged to fix the position of the workpiece in the loading groove 301. The first clamping rods 302 and the second clamping rods 303 are configured to rotate with the feeding tray 3. When moving to directly below the drilling machine 2, they move closer to each other and clamp the workpiece. Through the mutual cooperation of the first clamping rods 302 and the second clamping rods 303, the precise fixation of the position of the workpiece in the loading groove 301 is achieved. When the workpiece moves to directly below the drilling machine 2, the clamping rods automatically approach and clamp the workpiece, effectively preventing the offset and shaking during the machining process and improving the machining quality; an inner seat 4 is installed on the support frame 1 and is arranged inside the inner circle of the feeding tray 3; the inner seat 4 includes: a first raised block 401, installed on the outer circle of the inner seat 4, for when the second clamping rod 303 rotates with the feeding tray 3 and passes through the first raised block 401, the first raised block 401 presses the second clamping rod 303 to make the second clamping rod 303 approach the center of the loading groove 301; an outer seat 5 is installed on the support frame 1 and is arranged outside the outer circle of the feeding tray 3; the outer seat 5 includes: a second raised block 501, installed on the inner circle of the outer seat 5, for when the first clamping rod 302 rotates with the feeding tray 3 and passes through the second raised block 501, the second raised block 501 presses the first clamping rod 302 to make the first clamping rod 302 approach the center of the loading groove 301. The first raised block 401 and the second raised block 501 on the inner seat 4 and the outer seat 5 respectively press the first clamping rod 302 and the second clamping rod 303, realizing the automatic control of the clamping rods during the rotation of the feeding tray 3, simplifying the clamping mechanism, reducing the complexity and failure rate of mechanical components, and at the same time improving the accuracy and reliability of clamping.

[0032] Refer to Figure 2, the loading tray 3 further includes: a moving plate 304, connected within the loading groove 301 and configured to move within the loading groove 301 for ejecting the drilled workpiece out of the loading groove 301; a second magnetic member 305, one end of which is connected to the bottom of the moving plate 304, and the other end of which penetrates the bottom wall of the loading groove 301 and extends to the outside of the loading tray 3. A first magnetic member 103 is connected to the support frame 1 and is configured to repel the second magnetic member 305 with the same pole, so as to provide moving power for the second magnetic member 305. The moving design of the moving plate 304 within the loading groove 301, combined with the principle of repulsion between the same poles of the magnetic members, realizes the automatic ejection function of the drilled workpiece. This non-contact ejection method reduces mechanical wear and noise, and improves work efficiency and automation degree at the same time.

[0033] Referring to Figure 2 and Figure 3 , the support frame 1 includes: a power source 101, installed on the support frame 1; a first gear 102, installed on the power shaft of the power source 101. A second gear 306 is installed on the loading tray 3 and is connected to the first gear 102. The power source 101 provides the power required for the rotation and movement of the equipment, and the gear transmission system ensures the accuracy and reliability of power transmission, making the rotation of the loading tray 3 stable and uniform, and ensuring the continuity and stability of the workpiece during the processing. The power source 101 adopts a servo motor, and a stepper motor can also be used.

[0034] During use, after the device receives the start instruction, the power source 101 starts to work. The power source 101 drives the first gear 102 to rotate, and the first gear 102 drives the second gear 306 to rotate. The second gear 306 drives the feeding tray 3 to rotate. As the feeding tray 3 rotates, the loading groove 301 and the workpieces therein move successively to directly below the drilling machine 2. When the loading groove 301 containing the workpiece moves directly below the drilling machine 2, the first clamping rod 302 and the second clamping rod 303 are respectively squeezed by the first raised block 401 on the inner seat 4 and the second raised block 501 on the outer seat 5, and move towards the center of the loading groove 301, achieving precise clamping and fixing of the workpiece. The clamping process ensures the stability and position accuracy of the workpiece during processing. After the workpiece is clamped, the drilling machine 2 starts to perform drilling operations. During the drilling process, the workpiece remains stationary to ensure processing accuracy. After drilling is completed, the feeding tray 3 continues to rotate, moving the processed workpiece to the next station or a specific position. At the same time, due to the same-pole repulsion between the first magnetic part 103 on the support frame 1 and the second magnetic part 305 at the bottom of the loading groove 301, a repulsive force is generated to push the moving plate 304 to move upward in the loading groove 301. The moving plate 304 ejects the drilled workpiece out of the loading groove 301, realizing automatic unloading of the workpiece. The feeding tray 3 continues to rotate, and the next workpiece to be processed enters the drilling position, repeating the above processes of clamping, drilling, and ejecting. The entire process continues continuously to achieve multi-station continuous processing and improve production efficiency.

[0035] In summary, compared with the prior art, the following beneficial effects are achieved:

[0036] By arranging the first clamping rod 302 and the second clamping rod 303 on the feeding tray 3, these clamping rods can automatically approach and clamp the workpiece when the workpiece moves directly below the drilling machine 2, enabling each workpiece to be firmly fixed at a predetermined position before drilling, avoiding relative displacement between the drill bit and the workpiece, improving the drilling accuracy of a single workpiece, and ensuring the consistency of processing results between different stations.

[0037] By using the raised blocks on the inner seat 4 and the outer seat 5 to drive the automatic movement of the clamping rods, the design of the clamping mechanism is simplified. The non-mechanical transmission method reduces the number and complexity of mechanical components, reduces the failure rate, and also facilitates the maintenance and servicing of the device, helping to reduce maintenance costs and improve the reliability of the device.
