Description

Technical Field

[0001] This application relates to the field of deburring and cleaning technology for parts, and in particular to a flexible deburring device for connecting rods. Background Technology

[0002] Connecting rods, as widely used components in the mechanical field, have a significant impact on subsequent processing, assembly, and overall mechanical performance due to their surface quality. Deburring, a key process in connecting rod manufacturing, directly affects the quality and production efficiency of the connecting rod. With the continuous development of the machinery manufacturing industry, the requirements for the precision, efficiency, and automation of connecting rod deburring are becoming increasingly stringent. Traditional connecting rod deburring technology has met production needs to a certain extent, but its limitations are gradually becoming apparent as production scale expands and product quality requirements increase.

[0003] In the field of traditional connecting rod deburring, the following methods are commonly used to achieve deburring: First, in terms of positioning, production lines often use fixed blocks or simple V-grooves to position the connecting rods; second, deburring tools usually use brushes, but the power is relatively insufficient; third, in terms of the deburring process, it mainly relies on manual loading and unloading or visual inspection of burrs, and the positioning accuracy of the fixtures is also insufficient; fourth, for burr removal, there is a lack of reasonable and automated mechanisms, and it is mostly done manually or by independent air blowing.

[0004] However, traditional deburring methods for connecting rods have several problems: lacking an advanced positioning system, it's difficult to accurately position connecting rods with varying shapes and dimensions, resulting in inconsistent deburring effects and difficulty in completely removing burrs from all parts of the connecting rod surface. Furthermore, without a proper burr removal mechanism, removed burrs accumulate in the work area, affecting the normal operation of the production line and causing secondary contamination. In addition, deburring tools often lack sufficient power, failing to effectively remove stubborn burrs, increasing production time and costs, and failing to meet the demands of modern production. Utility Model Content

[0005] To address the issues of inconsistent deburring results, difficulty in completely removing burrs from all parts of the connecting rod surface, burr accumulation that cannot be properly discharged affecting the deburring efficiency of the production line, ambiguous positioning, limited compatibility with a single connecting rod, and the tendency for the connecting rod to lose attitude control during the positioning process, this application provides a flexible deburring device for connecting rods.

[0006] The flexible deburring device for connecting rods provided in this application adopts the following technical solution: A flexible deburring device for connecting rods includes a production line and a track mounted on a support frame on the production line. The production line is divided into a positioning section, a transmission section, a deburring execution section, and a chip removal section. The positioning section, transmission section, deburring execution section, and chip removal section are arranged sequentially along the transmission direction. The positioning section is equipped with a positioning mechanism for loading and positioning the connecting rod. The deburring execution section is equipped with a deburring execution mechanism for removing burrs from the connecting rod. The chip removal section is equipped with a chip removal mechanism for cleaning up debris from the deburring execution section.

[0007] By adopting the above technical solution, the production line is divided into a positioning section, a transmission section, a deburring execution section, and a chip removal section. The connecting rod is sequentially loaded, positioned, transmitted, deburred, and chip removed, realizing the process flow of connecting rod deburring operation. This solves the problems of uncontrolled posture, burr residue, and monotonous process in traditional connecting rod deburring production lines, and improves the automation and precision level of connecting rod deburring.

[0008] Optionally, the positioning mechanism includes a top block mounted on the track and an adjustable positioning stop mounted on one side of the top block, the adjustable positioning stop being used to collaboratively complete the linkage attitude control.

[0009] By adopting the above technical solution, the adjustable positioning block and the top block can work together to manually or electrically adjust the spacing and position according to the size of the connecting rod, and limit and clamp the connecting rod in the X and Y axis directions. This solves the problem of vague positioning and only being able to adapt to a single model in traditional production lines, and achieves precise control of the connecting rod's attitude, laying a good foundation for subsequent deburring operations.

[0010] Optionally, fixed rods are installed on both sides of the production line, and the deburring actuator includes a scraper rotatably arranged between the fixed rods, a fixed plate forming a certain angle between the scraper, and a spring installed between the fixed plate and the scraper, wherein the angle between the fixed plate and the scraper is 30°~45°.

[0011] By adopting the above technical solution, the spring-assisted scraper utilizes a "rigid scraping + elastic compensation" mechanism. The spring force ensures that the scraper and the connecting rod surface remain in continuous contact, which can remove stubborn burrs. The spring preload is adjustable to avoid excessive pressure that could damage the connecting rod surface. Compared with traditional manual or single rigid tools, it is more adaptable to the slight undulations on the connecting rod surface and significantly reduces the burr residue rate.

[0012] Optionally, a triangular apex block is provided on the transmission section. The triangular apex block and the track are connected by a dovetail groove structure. The inclined surface of the triangular apex block contacts the free end of the scraper. The relative movement generates a horizontal squeezing force that drives the scraper to rotate around the fixed rod.

[0013] By adopting the above technical solution, the dovetail groove structure enables the triangular top block to be quickly connected to the track, which can efficiently convert the linear thrust of the connecting rod into the driving force for the scraper rotation. The horizontal extrusion force generated by the contact between the inclined surface of the triangular top block and the free end of the scraper drives the scraper to rotate around the fixed rod, allowing the scraper to adhere to the surface of the connecting rod to be deburred under the combined action of the spring force and the extrusion force of the triangular top block, thereby achieving the scraping and removal of obvious burrs on the surface of the connecting rod.

[0014] Optionally, the debris removal mechanism includes a waste conveying pipe installed on one side of the conveyor line and an air head installed on the track. The waste conveying pipe is connected to the track, and the inlet of the waste conveying pipe is a flared flared opening. The cross-section of the waste conveying pipe is U-shaped.

[0015] By adopting the above technical solution, the waste conveying pipeline is connected to the track, and the inlet of the pipeline is a flared horn with a U-shaped cross-section. With the help of air blowing, burrs and debris can be guided to fall smoothly into the waste conveying pipeline. This effectively solves the problem of burrs accumulating in the gaps of the track and the grooves of the workpiece in traditional production lines, avoids secondary pollution, achieves immediate cleaning after deburring, improves the automation level of the production line, and reduces downtime.

[0016] Optionally, the air head is mounted on one side of the production line via an adjustable bracket, which is equipped with a three-dimensional adjustment button for adjusting its injection angle, height, and horizontal distance from the connecting rod.

[0017] By adopting the above technical solution, the spray angle, height and horizontal distance between the air head and the connecting rod can be precisely adjusted through the three-dimensional adjustment button, so that the high-pressure airflow accurately covers the area of ​​the connecting rod to be cleaned, effectively blowing away the fine burrs and debris left after the scraper deburred, avoiding the accumulation of burrs in the track gaps and connecting rod grooves and causing secondary pollution, thereby improving the automation level and production efficiency of the production line.

[0018] Optionally, an L-shaped mounting plate is provided on one side of the production line, and an infrared sensor is mounted on the L-shaped mounting plate. The sensing probe axis of the infrared sensor is parallel to the conveying plane and aligned with the connecting rod axis. The sensing distance of the infrared sensor is 50~100mm.

[0019] By adopting the above technical solution, the infrared sensor can accurately sense the deburring process after the connecting rod completes the deburring process and automatically trigger the air blowing cleaning action, realizing the automated connection between deburring and cleaning, avoiding burr accumulation and secondary pollution, improving the automation level and process continuity of the production line, and reducing downtime.

[0020] Optionally, a retaining plate is provided on one side of the fixed rod. The retaining plate is rotatably engaged with the side wall of the production line via a hinge. A pull rod for adjusting the brush state is provided on the side of the retaining plate away from the fixed rod. The pull rod is hinged to the retaining plate via a pin. A positioning pin hole is provided in the middle of the pull rod. The positioning pin hole engages with different gear pin holes on the side wall of the production line. The retaining plate is a metal plate with a magnetic adsorption surface. The retaining plate is used to unlock or lock the pull rod so that it swings down or up.

[0021] By adopting the above technical solution, a clamping plate and a pull rod are set on one side of the fixed rod. The clamping plate is hinged to the side wall of the production line for rotation. The pull rod is hinged to the clamping plate and the central positioning pin hole is matched with the pin holes of different gears on the side wall of the production line. The clamping plate is a metal plate with a magnetic adsorption surface that can be adsorbed to unlock or lock. Thus, the pull rod can be flexibly operated to make the brush swing down or up according to production needs, realizing flexible switching of the deburring process, adapting to different deburring requirements, avoiding unnecessary contact wear. At the same time, combined with other structures of the whole device, it can achieve functions such as precise positioning, efficient deburring, and automatic chip removal, solving the problems of uncontrolled posture, burr residue, and single process in traditional linkage deburring production lines.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The adjustable positioning stop and top block of the positioning mechanism work together to achieve accurate positioning at low cost, and can adapt to connecting rods of different sizes and specifications, solving the problems of vague positioning and only being able to adapt to a single model in traditional assembly lines; 2. The spring-assisted scraper of the deburring actuator uses a "rigid scraping + elastic compensation" mechanism to remove stubborn burrs while avoiding excessive pressure that could damage the connecting rod surface, effectively reducing the burr residue rate. 3. The combination of infrared sensing and air blowing in the chip removal mechanism enables immediate cleaning after deburring, avoiding burr accumulation and secondary pollution, and improving the automation level and process continuity of the production line.

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail.

[0031] This application discloses a flexible deburring device for connecting rods.

[0032] Reference Figure 1 and Figure 2 As shown, the assembly line includes a production line 1, a track 2, a positioning mechanism 3, a deburring execution mechanism 4, and a chip removal mechanism 5. The track 2 is mounted on a support frame on the production line 1. The production line 1 is divided into a positioning section 11, a transmission section 12, a deburring execution section 13, and a chip removal section 14. The positioning section 11, transmission section 12, deburring execution section 13, and chip removal section 14 are arranged sequentially along the transmission direction. The positioning mechanism 3 is located in the positioning section 11 for positioning the connecting rod during loading. The deburring execution mechanism 4 is located in the deburring execution section for removing burrs from the connecting rod. The chip removal mechanism 5 is located in the chip removal section 14 for removing chips removed from the deburring execution section 13. This achieves precise positioning of the connecting rod, efficient deburring, and automatic chip removal, thereby improving production efficiency and product quality. The various mechanisms work together at different stages, effectively solving the problems existing in the traditional production line 1.

[0033] See Figure 4As shown, the positioning mechanism 3 includes a top block 31 mounted on the track 2 and an adjustable positioning stop 32 mounted on one side of the top block 31. The adjustable positioning stop 32 is used to collaboratively control the linkage's attitude. The top block 31 can be a regular shape such as a cuboid and can be detachably fixed to the surface of the track 2 via a T-slot and fastening bolts. This connection method allows for a certain adjustment margin between the top block 31 and the track 2, and the spacing of the top block 31 on the track 2 can be finely adjusted according to the linkage's conveying rhythm and thrust requirements. The adjustable positioning stop 32 has a slider at its bottom, and the track 2 has a pre-set adjustment groove. The slider at the bottom of the stop is embedded in the groove, thus achieving precise fixation of the linkage's attitude in both the X and Y axes. The top block 31 and the adjustable positioning stop 32 cooperate with each other. The top block 31 is responsible for pushing the linkage forward, while the adjustable positioning stop 32 positions the linkage, ensuring the stability of the linkage's attitude during conveying and deburring.

[0034] See Figure 3 As shown, fixed rods 6 are installed on both sides of the production line 1. The deburring execution section 13 includes a scraper 41 rotatably arranged between the fixed rods 6, a fixed plate 42 forming a certain angle with the scraper 41, and a spring 43 installed between the fixed plate 42 and the scraper 41. The angle between the fixed plate 42 and the scraper 41 is 30°~45°. The fixed rod 6 is a rigid rod with mounting flanges at both ends. It is firmly fixed to the support columns on both sides of the production line 1 by means of expansion bolts and welding reinforcement. The scraper 41 is rotatably connected to the fixed rod 6 through a rotating shaft. The rotating shaft uses a bronze bushing as the rotating pair to ensure that the scraper 41 rotates smoothly without jamming around the fixed rod 6. The end cap of the rotating shaft is provided with a damping adjustment shim, which can finely adjust the rotation resistance of the scraper 41 to adapt to different deburring pressure requirements. Spring 43 is a cylindrical helical compression spring 43, which is fixed through a blind hole. Its axis forms a certain angle (generally 30° - 45°) with the rotation plane of scraper 41. This allows the elastic force of spring 43 to provide pressure for scraper 41 to adhere to the connecting rod, and also to generate a reasonable torque when scraper 41 rotates, assisting scraper 41 in resetting. When triangular top block 121 pushes scraper 41, spring 43 is compressed to generate a reverse elastic force, pressing scraper 41 tightly against the surface of connecting rod, thereby removing burrs from the surface of connecting rod.

[0035] See Figure 2 and Figure 3As shown, a triangular top block 121 is provided on the transmission section 12. The triangular top block 121 and the track 2 are connected by a dovetail groove structure. The inclined surface of the triangular top block 121 contacts the free end of the scraper 41. The relative motion generates a horizontal extrusion force, which drives the scraper 41 to rotate around the fixed rod 6. The triangular top block 121 adopts a dovetail groove structure for quick connection with the track 2, ensuring that when it contacts the scraper 41, the linear thrust of the connecting rod is efficiently converted into the driving force for the rotation of the scraper 41. When the connecting rod moves forward with the top block 31 to the deburring station, the front triangular top block 121 contacts the scraper 41 first. At the moment the inclined surface of the triangular top block 121 contacts the scraper 41, the relative motion generates a horizontal extrusion force, which forces the scraper 41 to compress the spring 43 assembly in a direction away from the connecting rod. The spring 43 generates a reverse elastic restoring force under compression, pressing the scraper 41 tightly against the surface of the connecting rod, thereby achieving the purpose of deburring.

[0036] See Figure 4 As shown, the debris removal section 14 includes a waste conveying pipe 51 installed on one side of the production line 1 and an air head 52 installed on the track 2. The waste conveying pipe 51 is connected to the track 2. The inlet of the waste conveying pipe 51 is a flared flared mouth, and the cross-section of the waste conveying pipe 51 is U-shaped. The waste conveying pipe 51 is a U-shaped sheet metal part, which is suspended by a bracket and fixed to the lower side of the production line 1 by sealant. The pipe inlet is flared to guide the burrs and debris to fall smoothly in accordance with the blowing direction of the air head 52. The air head 52 is fixed to the end of the deburring station on one side of the production line 1 by an adjustable bracket. The bracket is equipped with a three-dimensional adjustment knob, which can accurately adjust the spray angle, height and horizontal distance between the air head 52 and the connecting rod to ensure that the high-pressure airflow accurately covers the area to be cleaned by the connecting rod. When the connecting rod completes the deburring process of scraper 41 and continues to be conveyed to the detection area of ​​infrared sensor 7, the sensor triggers the air circuit control system. The high-pressure air head 52 quickly sprays out a directional airflow to accurately blow away the fine burrs and debris remaining on the surface and around the connecting rod. The burrs and debris blown off by the airflow are guided by gravity and airflow and fall into the waste conveying pipe 51. They are then conveyed through the pipe to the centralized collection device to avoid accumulation and pollution.

[0037] See Figure 2 As shown, an L-shaped mounting plate is installed on one side of the production line 1. An infrared sensor 7 is mounted on the L-shaped mounting plate. The sensing probe axis of the infrared sensor 7 is parallel to the conveying plane and aligned with the connecting rod axis. The sensing distance of the infrared sensor 7 is 50~100mm. The infrared sensor 7 is fixed to one side of the production line 1 by the L-shaped mounting plate. The sensing probe axis is parallel to the conveying plane of the connecting rod and aligned with the position that the connecting rod must pass through after deburring. The sensing distance is calibrated (generally 50-100mm) to ensure stable triggering of the air circuit action. When the connecting rod passes through the sensing area of ​​the infrared sensor 7, the sensor recognizes the object signal and triggers the air circuit control system, thereby realizing the automatic chip removal function.

[0038] See Figure 1 and Figure 5 As shown, a retaining plate 8 is provided on one side of the fixed rod 6. The retaining plate 8 is rotatably engaged with the side wall of the production line 1 via a hinge. A pull rod 9 for adjusting the brush state is provided on the side of the retaining plate 8 away from the fixed rod 6. The pull rod 9 is hinged to the retaining plate 8 via a pin. A positioning pin hole is provided in the middle of the pull rod 9. The positioning pin hole is engaged with the pin holes of different gears on the side wall of the production line 1. The retaining plate 8 is a metal plate with a magnetic adsorption surface. The retaining plate 8 is attracted to unlock or lock so that the pull rod 9 can swing down or up. One side of the clamping plate 8 with the attached magnet is rotatably connected to the fixed support on the side wall of the production line 1 via a hinge. The brush state adjustment lever 9 is hinged to the other end of the clamping plate 8 via a pin. The middle of the lever 9 has a positioning pin hole, which cooperates with the different position pin holes on the fixed support to realize the two-position switching of the brush: down (magnet attracts and unlocks, clamping plate 8 drives the brush to swing down) and up (magnet attracts and locks, clamping plate 8 swings up to make the brush detach from the workpiece). For the connecting rod that requires deep cleaning, the brush lifting and pressure can be adjusted by the brush state lever 9 to flexibly adapt to different deburring needs.

[0039] The implementation principle of the flexible deburring device for connecting rods in this embodiment is as follows: After the worker places the connecting rod stably on the starting position of the conveyor on the track 2 of the production line 1, the X-axis and Y-axis adjustment mechanisms of the adjustable positioning block 32 can be operated according to the actual size of the connecting rod (length, width, etc.): Rotate the length adjustment screw to drive the block to move along the slide groove of the track 2 until it is in close contact with one end face of the connecting rod; rotate the width fine adjustment knob to allow the side of the block to move slightly on the Y-axis, clamping the connecting rod from both sides, restricting the translation and rotation of the connecting rod in the X-Y plane, completing the posture fixation, laying the foundation for subsequent precise deburring, and starting the power system of the production line 1. The top block 31 on the track 2 moves in a uniform linear motion with the conveying mechanism. After the front end face of the top block 31 contacts the rear end face of the connecting rod, it moves the connecting rod forward along the track 2 by means of the conveying driving force. When the connecting rod moves forward with the top block 31 to the deburring station, the front end of the connecting rod pushes the triangular top block 121 forward synchronously. At the moment when the inclined surface of the triangular top block 121 contacts the free end of the scraper 41, a horizontal squeezing force is generated due to the relative motion. This squeezing force forces the scraper 41 to rotate around the fixed rod 6. During the rotation of the scraper 41, the spring 43 is stretched. The spring 43 is stretched and undergoes elastic deformation, accumulating a reverse elastic force. As the connecting rod continues to move forward, the scraper 41, under the combined action of the elastic force of the spring 43 and the squeezing force of the triangular top block 121, presses against the surface of the connecting rod to be deburred with a certain pressure. The wear-resistant scraping edge of the scraper 41 slides relative to the connecting rod as it is conveyed. Through scraping and cutting actions, the obvious burrs on the surface of the connecting rod are cut off and peeled off. When the connecting rod completes the deburring process of the scraper 41 and continues to be conveyed along the track 2 to the detection area of ​​the infrared sensor 7, the connecting rod triggers the photoelectric signal of the infrared sensor 7. The sensor transmits the electrical signal to the air circuit control unit. The control unit quickly opens the air valve, and the high-pressure air source sprays out a directional airflow through the air head 52. Airflow sweeps the surface of the connecting rod and the gaps in the track 2 at a specific angle (such as a 20° tilt angle), blowing away the fine burrs and debris remaining after the scraper 41 removes the burrs. These debris are guided by gravity and airflow and fall into the funnel inlet of the waste conveying pipe 51. They are then transported through the pipe to the debris collection device outside the workshop for centralized processing. If secondary cleaning of special parts of the connecting rod is required during production, the worker can operate the brush state adjustment lever 9. Pulling the lever 9 causes the clamping plate 8 with the attached magnet to rotate around the hinge. After the magnet is removed from the adsorption position, the clamping plate 8 drives the brush assembly to swing down to the working position, and the brush contacts the surface of the connecting rod. When inserted into the corresponding position, the brush, relying on its own weight and the pre-tension of the lever 9, is conveyed with the connecting rod to remove burrs from special parts.When brushing is no longer needed, the reverse operation lever 9 is activated, the clamping plate 8 swings upward, the magnet re-attaches and locks, and the brush lifts up and detaches from the workpiece, achieving a flexible switch in the deburring process. Throughout the process, the track 2 serves as the basic support, the top block 31 and the adjustable positioning stop 32 work together to complete the linkage conveying and attitude control, the triangular top block 121, the scraper 41 and the spring 43 construct the mechanical deburring actuator 4, and the infrared sensor 7, the air head 52 and the waste conveying pipe 51 form an intelligent chip removal system. The lever 9 adjusts the brush state and works with the magnet clamping plate 8 to achieve flexible process adaptation. Through precise connection and orderly movement, each component forms a complete closed loop of operation: "positioning → conveying → mechanical deburring → intelligent chip removal → flexible process switching", which efficiently solves the problems of attitude loss, burr residue and single process in the traditional linkage deburring production line 1.
