Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a drilling processing equipment for assembling automotive parts. Background Technology

[0002] In the automotive manufacturing industry, the assembly precision of parts directly determines the performance and safety of the entire vehicle. Drilling, as a key process in automotive parts production, has a significant impact on the subsequent assembly process in terms of its processing quality and efficiency. As the automotive industry develops towards lightweighting and integration, the structure of parts is becoming increasingly complex, and the requirements for the precision, stability, and working environment of drilling are also constantly increasing.

[0003] To ensure machining accuracy, existing drilling equipment uses clamps to hold the automotive parts to be processed. While this improves machining accuracy, it only allows the automotive parts to be parallel to the worktable during fixing. When it is necessary to drill at an angle, the fixed automotive parts need to be manually readjusted and fixed again, making the equipment time-consuming and labor-intensive.

[0004] An existing patent (publication number: CN220372272U) discloses a drilling device for automotive parts, comprising a base, an adjustment component for extending the drilling range mounted on the side of the base, and a drilling component for drilling automotive parts mounted on the side of the adjustment component. A support plate is vertically welded to the inner side of the base, and a driven shaft is mounted between the side of the support plate and the vertical inner wall of the base. The top of the driven shaft is connected to a worktable via at least two connecting rods, and a clamping structure for fixing automotive parts is mounted on the outer end of the worktable. A drive shaft is mounted on the side of the support plate where the driven shaft is mounted, and gears are mounted on the sides of both the drive shaft and the driven shaft, with the two gears meshing together. This drilling device for automotive parts is easy to adjust and does not require multiple fixings of the parts, saving time and effort.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, these drilling devices lack effective auxiliary positioning structures during drilling operations. Relying solely on clamping structures makes it difficult to completely prevent the minute displacements of parts during drilling, especially for automotive parts with smooth surfaces or irregular shapes. The rotating impact force of the drill bit can easily cause workpiece displacement, affecting drilling accuracy. At the same time, metal chips and dust generated during drilling cannot be handled in a timely manner, which not only pollutes the processing environment but may also adhere to the drill bit and workpiece surface, thereby accelerating drill bit wear and affecting subsequent assembly quality.

[0006] To address this, a drilling equipment for assembling automotive parts is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a drilling equipment for assembling automotive parts, which can solve the problems of existing drilling devices lacking effective auxiliary positioning structures during drilling operations. Relying solely on clamping structures is insufficient to completely prevent the slight displacement of parts during drilling, especially for automotive parts with smooth surfaces or irregular shapes. The rotating impact force of the drill bit can easily cause workpiece displacement, affecting drilling accuracy. At the same time, the metal chips and dust generated during drilling are not handled in a timely manner, which not only pollutes the processing environment but may also adhere to the drill bit and workpiece surface, thereby accelerating drill bit wear and affecting subsequent assembly quality.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a drilling processing equipment for assembling automotive parts, comprising a base, a bracket fixedly connected to the rear side of the top of the base, a drill bit disposed inside the bracket, and an auxiliary mechanism disposed outside the drill bit, the auxiliary mechanism comprising a positioning component and a dust removal component, the positioning component comprising a U-shaped frame, upright plates fixedly connected to both sides of the bottom of the U-shaped frame, and vertical holes formed on the inner walls of both upright plates, a limit rod fixedly connected inside the vertical hole, a connecting rod slidably connected to the surface of the limit rod, a pressure plate disposed at the bottom of the connecting rod, the bottom of the pressure plate being coated with an anti-slip coating, and a spring sleeved on the surface of the limit rod, the two ends of the spring being fixedly connected to the inner wall of the vertical hole and the top of the connecting rod, respectively.

[0009] Preferably, the dust removal assembly includes an adsorption chamber and the number of adsorption chambers is set to two, and the adsorption chambers are fixedly connected between the connecting rod and the pressure plate on opposite sides.

[0010] Preferably, suction holes are provided on opposite sides of the two adsorption chambers, and the number of suction holes is set to multiple and evenly distributed.

[0011] Preferably, a flexible tube is fixedly connected to the rear side of the adsorption chamber, and the other end of the flexible tube passes through the bracket and is fixedly connected to a vacuum cleaner, which is fixedly installed on the rear side of the bracket.

[0012] Preferably, a placement plate is fixedly connected to the top of the base, and side plates are fixedly connected to both sides of the top of the placement plate. An electric push rod is fixedly installed inside the side plate, and a clamping plate is fixedly connected to the telescopic end of the electric push rod.

[0013] Preferably, a rotary motor is fixedly installed at the bottom of the base, and the output shaft of the rotary motor passes through the base and is fixedly connected to the bottom of the placement plate.

[0014] Preferably, the top of the bracket has a movable square hole, and a threaded rod is rotatably connected to the inside of the movable square hole through a bearing. The front end of the threaded rod is fixedly connected to a first motor, and a threaded block is threadedly connected to the surface of the threaded rod and the threaded block is slidably connected to the movable square hole.

[0015] Preferably, an electric cylinder is fixedly installed at the bottom of the threaded block, and a mounting frame is fixedly connected to the telescopic end of the electric cylinder. A second motor is fixedly installed inside the mounting frame, and the output shaft of the second motor passes through the mounting frame and is fixedly connected to the top of the drill bit.

[0016] Preferably, the U-shaped frame is fixedly connected to the bottom of the mounting frame, and a circular hole is provided in the middle of the U-shaped frame with the drill bit located inside the circular hole.

[0017] Preferably, a guide rod is fixedly connected inside the movable square hole, and the threaded block is slidably connected to the surface of the guide rod.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This application sets up a positioning component. When the drill bit moves downward to perform drilling operations, the pressure plate will first contact the workpiece surface. As the drill bit continues to move downward, the spring force will keep the pressure plate tightly pressed against the workpiece surface. Combined with the anti-slip coating on the bottom, it can effectively prevent the workpiece from undergoing slight displacement due to the impact force of the drill bit during the drilling process, and realize the auxiliary positioning of the workpiece. This is especially useful for automotive parts with smooth surfaces or irregular structures, thereby significantly improving drilling accuracy and stability.

[0020] 2. By setting up a dust removal component, during drilling operations, the vacuum cleaner creates negative pressure inside the adsorption chamber through a hose. Metal chips and dust generated during drilling are quickly sucked into the adsorption chamber through the suction hole, and then collected by the vacuum cleaner through the hose. At the same time, since the dust removal component is close to the drilling area, it can remove chips and dust generated during processing in a timely and efficient manner. This not only improves the working environment and reduces the impact on the health of operators, but also avoids the aggravation of drill bit wear and subsequent assembly quality problems caused by chips adhering to the drill bit and workpiece surface.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 The present invention provides the following technical solution:

[0029] A drilling processing equipment for assembling automotive parts includes a base 1, a bracket 2 fixedly connected to the rear side of the top of the base 1, a drill bit 3 disposed inside the bracket 2, and an auxiliary mechanism 4 disposed outside the drill bit 3. The auxiliary mechanism 4 includes a positioning component 41 and a dust removal component 42. The positioning component 41 includes a U-shaped frame 411, upright plates 412 fixedly connected to both sides of the bottom of the U-shaped frame 411, and vertical holes 413 are opened on the inner walls of the two upright plates 412. A limit rod 414 is fixedly connected inside the vertical hole 413. A connecting rod 415 is slidably connected to the surface of the limit rod 414. A pressure plate 416 is disposed at the bottom of the connecting rod 415 and the bottom of the pressure plate 416 is coated with an anti-slip coating. A spring 417 is sleeved on the surface of the limit rod 414. The two ends of the spring 417 are fixedly connected to the inner wall of the vertical hole 413 and the top of the connecting rod 415, respectively.

[0030] In this embodiment: by setting a positioning component 41, the U-shaped frame 411 is the basic frame of the positioning component 41, used to connect and fix the upright plate 412, ensuring that the pressure plate 416 can be accurately aligned with the drilling area; the upright plate 412 is the mounting carrier of the limiting rod 414, which can provide vertical support for the positioning component 41, and the vertical hole 413 is used to accommodate the limiting rod 414, limit the sliding direction of the connecting rod 415, and prevent it from shifting laterally when moving up and down, ensuring that the pressure plate 416 exerts vertical downward pressure on the workpiece; the limiting rod 414 can limit the sliding trajectory of the connecting rod 415, preventing the connecting rod 415 from tilting and shaking under the elastic force of the spring 417 or the reaction force of the workpiece, ensuring that the pressure plate 416 always presses steadily on the surface of the workpiece, and avoiding local displacement of the workpiece due to uneven force; the connecting rod 415 is the mounting carrier of the limiting rod 414, which can provide vertical support for the positioning component 41, and the vertical hole 413 is used to accommodate the limiting rod 414, limiting the sliding direction ... ensuring that the vertical hole 415 can exert vertical downward pressure on the workpiece, and ensuring that the vertical hole 416 exerts vertical downward pressure on the workpiece, and ensuring that the vertical hole 416 exerts vertical downward pressure on the workpiece, and The connecting component between plate 16 and vertical plate 412 is used to transmit the elastic force of spring 417 to pressure plate 416. At the same time, it can slide up and down along limit rod 414. In conjunction with the lifting and lowering action of drill bit 3, it realizes the linkage effect that when drill bit 3 moves down, pressure plate 416 first presses the workpiece, and when drill bit 3 returns to its original position, pressure plate 416 simultaneously disengages. Pressure plate 416 can directly contact the surface of workpiece and press the workpiece tightly through the elastic force of spring 417, offsetting the rotational impact force generated when drill bit 3 drills, preventing slight displacement of workpiece. In addition, the anti-slip coating on its bottom can increase the friction between pressure plate 416 and workpiece surface. Especially for smooth automotive parts, it can further improve pressing stability and avoid slippage. The elastic characteristics of spring 417 can automatically adjust the compression amount according to the thickness of workpiece to ensure that parts of different thicknesses can be pressed smoothly.

[0031] Specifically, such as Figure 2 , Figure 3 As shown, the dust removal assembly 42 includes an adsorption chamber 421 and the number of adsorption chambers 421 is set to two. The adsorption chamber 421 is fixedly connected between the connecting rod 415 and the pressure plate 416 on opposite sides.

[0032] Specifically, such as Figure 3 As shown, each of the two adsorption chambers 421 has a suction hole 422 on one side opposite to the other, and the number of suction holes 422 is set to multiple and evenly distributed.

[0033] Specifically, such as Figure 3 As shown, a flexible hose 423 is fixedly connected to the rear side of the adsorption chamber 421. The other end of the flexible hose 423 passes through the bracket 2 and is fixedly connected to a vacuum cleaner 424. The vacuum cleaner 424 is fixedly installed on the rear side of the bracket 2.

[0034] In this embodiment: By setting up the dust removal component 42, the adsorption chamber 421 serves as the collection channel for debris and dust. It can move synchronously with the positioning component 41 to ensure that it always maintains a close distance to the drilling area, thereby ensuring that the dust collection range accurately covers the processing point and improving the debris capture efficiency. The suction holes 422 are the entrances for debris to enter the adsorption chamber 421. The design of multiple evenly distributed holes can expand the dust collection range and simultaneously adsorb debris from different angles of the drilling area, avoiding the problem of missed suction caused by the limited position of a single suction hole 422. It is especially effective for capturing more comprehensive debris generated by the rotation of the drill bit 3. The flexible hose 423 connects the adsorption chamber 421 to the vacuum cleaner 424, providing a flexible channel for conveying debris. It can freely extend and retract with the movement of the positioning component 41 and the drill bit 3, ensuring the continuity of the vacuuming operation. The vacuum cleaner 424 is the power source of the dust removal component 42. By generating negative pressure, it creates airflow in the adsorption chamber 421, which can suck in the metal debris and dust generated during drilling from the suction hole 422 and pump them through the flexible hose 423 to the inside of the vacuum cleaner 424 for collection. This fundamentally solves the problem of debris scattering, thereby achieving a clean processing environment and protecting the health of operators.

[0035] Specifically, such as Figure 1 , Figure 5 As shown, a placement plate 5 is fixedly connected to the top of the base 1, and side plates 6 are fixedly connected to both sides of the top of the placement plate 5. An electric push rod 7 is fixedly installed inside the side plate 6, and a clamping plate 8 is fixedly connected to the telescopic end of the electric push rod 7.

[0036] Specifically, such as Figure 1 As shown, a rotary motor 9 is fixedly installed at the bottom of the base 1, and the output shaft of the rotary motor 9 passes through the base 1 and is fixedly connected to the bottom of the placement plate 5.

[0037] In this embodiment: With the above settings, the placement plate 5 serves as a support platform for the workpiece, providing a stable foundation for the placement of automotive parts; the side plate 6 provides stable support for the electric push rod 7, ensuring that the electric push rod 7 will not shake during telescopic drive, thus guaranteeing the reliability of workpiece clamping; the electric push rod 7 can drive the clamping plate 8 to move horizontally through telescopic movement, thereby achieving lateral clamping or loosening of workpieces of different sizes; the clamping plate 8 can directly contact the side of the workpiece, firmly fixing the workpiece to the top of the placement plate 5 under the driving force of the electric push rod 7, and can cooperate with the top pressing of the positioning component 41 to form a double fixation of lateral clamping + top pressing, further preventing the workpiece from shifting during drilling; the rotary motor 9, with its output shaft connected to the bottom of the placement plate 5, can drive the placement plate 5 to rotate the workpiece, realizing the drilling requirements of different angles of the workpiece, without the need for manual disassembly and repositioning, greatly improving the flexibility and efficiency of multi-angle processing.

[0038] Specifically, such as Figure 1As shown, the top of the bracket 2 is provided with a movable square hole 10. The interior of the movable square hole 10 is rotatably connected to a threaded rod 11 via a bearing, and the front end of the threaded rod 11 is fixedly connected to a first motor 12. The surface of the threaded rod 11 is threadedly connected to a threaded block 13, and the threaded block 13 is slidably connected to the movable square hole 10.

[0039] Specifically, such as Figure 1 , Figure 4 As shown, an electric cylinder 14 is fixedly installed at the bottom of the threaded block 13. The telescopic end of the electric cylinder 14 is fixedly connected to a mounting frame 15. A second motor 16 is fixedly installed inside the mounting frame 15. The output shaft of the second motor 16 passes through the mounting frame 15 and is fixedly connected to the top of the drill bit 3.

[0040] In this embodiment: Through the above settings, the movable square hole 10 provides installation and movement space for the threaded rod 11 and the threaded block 13, while limiting the sliding trajectory of the threaded block 13 so that it can only move horizontally along the square hole, preventing the threaded block 13 from rotating with the rotation of the threaded rod 11, and ensuring that the horizontal adjustment direction of the drill bit 3 is stable and does not deviate; when the first motor 12 is working, it can drive the threaded rod 11 to rotate, and the threaded rod 11 can drive the threaded block 13 to move through the threaded transmission, thereby driving the electric cylinder 14 below and the drill bit 3 to adjust horizontally synchronously, realizing precise control of the position of the drill bit 3 in the lateral direction, thereby meeting the needs of different drilling positions; the electric cylinder 14 can provide vertical lifting power for the drill bit 3, and through the extension and retraction action, it drives the mounting frame 15, the second motor 16 and the drill bit 3 to move up and down synchronously. Furthermore, the electric cylinder 14 can precisely control the extension and retraction stroke, enabling precise adjustment of the drilling depth of the drill bit 3. Simultaneously, it drives the drill bit 3 to move downwards towards the workpiece before drilling and resets it after drilling, completing the automated drilling action. The mounting frame 15 serves as a fixed carrier for the second motor 16, providing a stable mounting space and preventing the second motor 16 from shaking during high-speed rotation. The mounting frame 15 connects the electric cylinder 14 and the drill bit 3, transmitting the vertical power of the electric cylinder 14 to the drill bit 3, ensuring stable and unbiased rotation of the drill bit 3 during drilling. When the second motor 16 is working, it can drive the drill bit 3 to rotate at high speed, using rotational cutting force to drill automotive parts. The speed of the second motor 16 can be adjusted according to the material of the parts and drilling requirements, ensuring drilling efficiency and quality.

[0041] Specifically, such as Figure 2 As shown, the U-shaped frame 411 is fixedly connected to the bottom of the mounting frame 15, and a round hole 17 is provided in the middle of the U-shaped frame 411, with the drill bit 3 located inside the round hole 17.

[0042] Specifically, such as Figure 1 As shown, a guide rod 18 is fixedly connected inside the movable square hole 10, and a threaded block 13 is slidably connected to the surface of the guide rod 18.

[0043] In this embodiment: Through the above settings, the U-shaped frame 411 can fix the positioning component 41 to the bottom of the mounting frame 15, ensuring that the positioning component 41 can move synchronously with the mounting frame 15 and the drill bit 3, and ensuring that the pressure plate 416 is always aligned with the drilling area; the round hole 17 can provide a through channel for the drill bit 3, allowing the drill bit 3 to pass through the U-shaped frame 411 and extend to the workpiece below, without obstructing the drilling action of the drill bit 3; the guide rod 18 can guide and limit the horizontal movement of the threaded block 13. When the first motor 12 drives the threaded rod 11 to rotate, the threaded block 13 will slide along the guide rod 18 while moving horizontally along the threaded rod 11, avoiding the threaded block 13 from twisting or shifting due to the rotational force of the threaded rod 11, ensuring that the threaded block 13 drives the lower electric cylinder 14, drill bit 3 and other structures to always move smoothly in a straight line, further improving the accuracy and stability of the horizontal position adjustment of the drill bit 3.

[0044] Working principle: First, the automotive part to be drilled is placed stably on top of the placement plate 5. Then, the electric push rod 7 is activated, causing the clamping plate 8 to move horizontally towards the workpiece until the clamping plates 8 on both sides clamp the workpiece laterally. Then, the first motor 12 is activated, which drives the threaded rod 11 to rotate. The threaded block 13, which is threaded to the threaded rod 11, slides horizontally along the guide rod 18 until the drill bit 3 below the threaded block 13 moves directly above the target hole on the workpiece. Then, the second motor 16 is activated, which drives the drill bit 3 to rotate at high speed. At the same time, the electric cylinder 14 is activated, causing the electric cylinder 14 to push the mounting frame 15, the drill bit 3, and the U-shaped frame 411 at the bottom to move downwards synchronously. During the downward movement of the drill bit 3, the pressure plate 416 of the positioning component 41 will first contact the surface of the workpiece. As the electric cylinder 14 continues to push, the connecting rod 415 will slide upwards along the limiting rod 414 in the vertical hole 413 of the upright plate 412. The drill bit 3 moves, compressing the spring 417. The spring force of the spring 417 will cause the pressure plate 416 to press tightly against the workpiece, preventing the workpiece from shifting due to the impact force of the drill bit 3. At the same time, the vacuum cleaner 424 is started. The vacuum cleaner 424 will create negative pressure in the suction chamber 421 through the hose 423. The debris and dust generated by the drill bit 3 will be sucked into the suction chamber 421 through the suction hole 422, and then transported to the vacuum cleaner 424 for collection through the hose 423, thus achieving simultaneous dust removal. When the drill bit 3 drills to the preset depth, the electric cylinder 14 is controlled to drive the drill bit 3 to reset upward. The second motor 16 and the vacuum cleaner 424 are turned off simultaneously. During the reset process, the spring 417 rebounds and pushes the connecting rod 415 and the pressure plate 416 to move downward, so that the positioning component 41 can return to the initial state. Finally, the electric push rod 7 is started, which drives the clamping plate 8 to retract to both sides, thereby releasing the lateral clamping of the workpiece. The operator can then remove the processed workpiece from the placement plate 5.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
