Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of fastener processing equipment, and in particular relates to a bolt tail integrated processing equipment. Background Art
[0002] In aerospace equipment manufacturing, aircraft skin connection technology plays a crucial role in structural safety and reliability. Traditional welding processes are prone to microcracks under alternating loads and extreme temperatures, and some aircraft structural failures are attributed to fatigue damage in welded areas. Therefore, modern aviation manufacturing is widely adopting high-precision bolting technology to replace traditional welding processes, achieving a reliable connection between the skin and the frame structure through bolted connections. This connection method improves stress uniformity and significantly reduces the risk of structural failure.
[0003] Currently, the mainstream process for forming the inner concave hole at the tail end of the bolt adopts manual operation. Operators need to frequently change processing tools of different specifications, resulting in long processing time for each piece and large deviation in positioning accuracy, which makes it difficult to meet the requirements of aviation quality standards. Although some companies have tried to use automatic or semi-automatic equipment for processing, the existing equipment generally has the problem of process discreteness, which is typically manifested in that chamfering, punching, punching, chip removal and other processes need to be completed on multiple independent devices, resulting in a large proportion of time spent on process conversion. Summary of the Invention
[0004] In order to solve at least one of the above technical problems, the present invention discloses an integrated bolt tail processing equipment, which is aimed at the tail processing of aerospace fasteners. It can ensure processing accuracy and reduce process time in a single process or a continuous process, and realize mass production in an assembly line manner.
[0005] The specific technical solutions of the present invention are as follows:
[0006] A bolt tail integrated processing device includes a feed track, at least one processing station is arranged along the feed track, the feed track includes a track 1 and a track 2, a material accommodating gap is formed between the track 1 and the track 2, the workpiece moves in the material accommodating gap, the feed track has a station track section, the station track section and the processing station are arranged accordingly, in the station track section, the position of the track 1 relative to the horizontal plane is higher than the track 2, so that the workpiece moves along the feed track inclined with respect to the horizontal plane, and the workpiece is processed at each processing station in turn along the feed track;
[0007] A tightening mechanism and a processing mechanism are provided at any processing station. The tightening mechanism includes a fixed positioning tool and a movable positioning tool that are relatively arranged. A part of the fixed positioning tool is configured as a material conveying track. The fixed positioning tool is provided with a first positioning groove, and the movable positioning tool is provided with a second positioning groove. When the workpiece moves to the processing station, the movable positioning tool clamps the workpiece between the first positioning groove and the second positioning groove, so that the processing mechanism processes the workpiece.
[0008] The movement direction of the tightening mechanism is parallel to the conveying surface of the feed track that is inclined relative to the horizontal plane, and the processing axis of the processing mechanism is perpendicular to the movement direction of the tightening mechanism.
[0009] In the present application, the feed track can transport the workpiece to each processing station in batches. When the workpiece is located at the processing station, the workpiece is clamped by positioning groove one and positioning groove two, so that the processing mechanism can realize precise processing of the workpiece. Since each processing station has different processing contents, targeted processing can be realized when the workpiece is located at different processing stations, thereby effectively improving the processing efficiency of the tail of the workpiece; since in the station track section, the position of track one relative to the horizontal plane is higher than track two, the conveying surface of the feed track for the workpiece is inclined to the horizontal plane, so that the workpiece is also axially inclined to the horizontal plane during the actual movement process. Therefore, after the workpiece is processed at a certain processing station, when the movable positioning tool is away from the fixed positioning tool, the workpiece after processing will withdraw from positioning groove one due to gravity, and then move toward the next processing station or withdraw from the processing equipment through the power source or its own gravity. In this way, the movement of the workpiece in the feed track can be realized by pushing the previous workpiece with the next workpiece, thereby improving the process fluency and thus improving the process efficiency.
[0010] Preferably, the fixed positioning tool is further provided with a posture adjustment member, and the posture adjustment member cooperates with the end surface of the workpiece to keep the axis of the workpiece in the first positioning groove coincident with the processing axis of the processing mechanism.
[0011] Since the conveying surface of the feed track is inclined to the horizontal plane, when the workpiece moves in the feed track, the workpiece has a "top-heavy" structure, and the end of the workpiece is in sliding contact with the track surface of the feed track. Therefore, the end of the workpiece is not in full contact with the track surface of the feed track. This makes it possible to not fully correct the processing posture of the workpiece when the workpiece is clamped in positioning groove one and positioning groove two. Therefore, on the basis of setting the posture adjustment part, when the movable positioning tool drives the workpiece to move into positioning groove one, the posture adjustment part and the end surface of the workpiece cooperate, and then the posture adjustment part is used to guide the movement of the workpiece, so that the workpiece is continuously adjusted relative to the processing axis of the processing mechanism through the force of the posture adjustment part, thereby ensuring that when the workpiece is in positioning groove one, the end surface of the workpiece can be in full contact with the track surface of the feed track, thereby ensuring that the processing axis of the processing mechanism is aligned with the axis of the workpiece, thereby achieving precise processing.
[0012] Preferably, when the workpiece is located in the first positioning groove, the bottom surface of the posture adjustment member covers an area of the end surface of the workpiece that is no more than 1 / 2 of the end surface area of the workpiece.
[0013] If the posture adjustment part achieves full contact with the workpiece, the probability of surface damage to the workpiece may increase during the process of movable positioning tooling. Therefore, in order to meet the posture adjustment requirements of the workpiece and avoid damage to the workpiece as much as possible, the posture adjustment part in this application achieves non-full contact with the workpiece, thereby meeting the above-mentioned process requirements.
[0014] Preferably, the fixed positioning fixture has an adjustment mechanism for adjusting the relative position between the posture adjustment member and the first positioning groove.
[0015] For different types of workpieces, the position of the posture adjustment part can be adjusted by adjusting the mechanism, which can help expand the application range of the processing equipment.
[0016] Preferably, the feed track further comprises a transition track section intersecting with the work station track section, and the workpiece enters the work station track section from the transition track section;
[0017] There is a height difference between adjacent transition rail segments and workstation rail segments. Along the movement path of the workpiece, the position of the previous workstation rail segment is higher than the position of the next workstation rail segment.
[0018] The track of this structure can meet the requirements of the workpiece sliding from top to bottom, which is conducive to using the gravity of the workpiece to achieve self-motion.
[0019] Preferably, in adjacent transition rail segments and work station rail segments, compared with the horizontal plane, the end of the transition rail segment is not less than 0.5 mm higher than the work station rail segment.
[0020] In the present application, at the junction between the first transition rail segment and the first workstation rail segment, there is a height difference between the two rail segments, which is equivalent to not being directly connected, but having a small step structure. This structure can prevent the workpiece from getting stuck and ensure sliding stability. This structure can also avoid docking size problems caused by mechanical vibration, further ensuring the sliding stability of the workpiece.
[0021] Preferably, the workpiece moves along a path parallel to the horizontal plane in the station rail section;
[0022] The material moving mechanism further comprises a material moving piece that can be switched between a first position and a second position, and the material moving piece drives the workpiece to move so as to switch the position of the workpiece;
[0023] The material transfer piece is used to achieve at least one of the following: transferring the workpiece in the previous workstation track segment to the transition track segment, and transferring the workpiece in the transition track segment to the next workstation track segment.
[0024] In order to ensure the clamping stability and processing accuracy of the workpiece at the processing station, the workpiece moves along a path parallel to the horizontal plane in the workstation rail segment. Therefore, when the workpiece is at the processing station, it does not slide by gravity, and a material transfer mechanism is required to achieve displacement. The material transfer mechanism can meet the transfer requirements of the workpiece, thereby achieving the purpose of transitioning the workpiece between different tracks or rail segments.
[0025] Preferably, the material transfer piece is provided with a receiving portion, and when the material transfer piece is located at the first position, the material transfer piece carries the workpiece through the receiving portion, so as to transfer the workpiece to the processing station when switching to the second position;
[0026] And / or, the material moving piece is provided with a pushing top portion. When the material moving piece is in the first position, the pushing top portion avoids positioning groove one. When the workpiece exits positioning groove one, the workpiece and the pushing top portion cooperate, and the material moving piece switches to the second position to transfer the workpiece out of the processing station.
[0027] When the workpiece is moved from the loading rail to the loading rail, the workpiece falls on the receiving portion, and the workpiece is moved from the loading rail to the loading rail, thereby the workpiece is moved to the loading rail.
[0028] Preferably, the feed track is connected with a lifting mechanism for adjusting the relative height of the feed track;
[0029] And / or, the track 2 is connected to a power mechanism for adjusting the relative position between the track 1 and the track 2
[0030] For different types of workpieces, the positions of track one and track two are adjusted through the lifting mechanism, and the position of track two is adjusted through the power mechanism, which can help expand the application range of the processing equipment.
[0031] Preferably, a plurality of processing stations connected in series are provided on the feed track, and a material moving mechanism is provided on one side of each processing station, and the material moving mechanism moves along the arrangement direction of the processing stations to move the workpiece into or out of the processing station;
[0032] The material moving mechanism and the movable positioning fixture are driven by different driving mechanisms, or the material moving mechanism and the movable positioning fixture are driven by the same driving mechanism.
[0033] In the present application, there is a mutual match between the movements of the material moving mechanism and the movable positioning tooling, which is beneficial to improving process efficiency. According to the actual process conditions, the movement of the material moving mechanism and the movement of the movable positioning tooling may be carried out simultaneously or at different times. Therefore, the material moving mechanism and the movable positioning tooling can be driven independently by different driving mechanisms, or can be driven by the same driving mechanism. If driven by the same driving mechanism, it can be achieved through intermediate components such as cams and differentials.
[0034] Preferably, the material moving mechanism and the movable positioning tool are driven by the same driving mechanism; the driving mechanism includes a camshaft and a reset member; the camshaft extends along the arrangement direction of the processing stations, and has a cam 1 that cooperates with the connecting rod mechanism, and a cam 2 that cooperates with the movable positioning tool; the reset member 1 is used to drive the material moving mechanism to reset.
[0035] In order to simplify the structure and reduce the volume of the processing equipment, the present application uses a camshaft to realize the movement of the material moving mechanism and the movable positioning tooling. It should be noted that, since the process time of different processing stations is different, and there is a transition section between the latter processing station and the previous processing station, based on the same reference line perpendicular to the camshaft axis, different cams 2 have different deflection angles, thereby constituting differential actions between different tightening mechanisms, and the setting of all cams 2 is determined based on the driving time of a pair of cam connecting rod mechanisms. Therefore, for the entire process flow, it can adapt well to the processing rhythm of each process stage and the position switching rhythm of the workpiece from front to back; and since cam 1 and cam 2 are both driven by pushing, for the material moving mechanism, it is necessary to use reset member 1 to realize the reset of the mechanism, and for the tightening mechanism, the tightening mechanism is tilted, so that it can be reset by its own gravity. Of course, reset member 1 can also be used to assist in realization.
[0036] Preferably, the material moving mechanism includes a sliding seat and a fixed seat, the sliding seat and the fixed seat are slidably matched, and brackets are provided at both ends of the sliding seat, and the brackets at both ends of the sliding seat correspond to two processing stations respectively;
[0037] The material moving mechanism further comprises a power rod, which can swing along a hinge point, is connected to a sliding seat, and is in sliding fit with a cam.
[0038] The movement of the power rod can drive the movement of the sliding seat, thereby driving the workpiece at multiple processing stations at the same time, so that different workpieces enter or exit at different processing stations to meet the continuity of the process.
[0039] Preferably, one side of one of the brackets is connected to the sliding seat, and the other side is provided with a follower base, or the sliding seat is provided with a follower base;
[0040] The follower base is provided with a slideway perpendicular to the sliding direction of the sliding seat, and the slideway is provided with a follower that slides with it; the power rod is provided with a slide groove along its axis, and the follower also slides with the slide groove.
[0041] The structure is simple and easy to implement, and can well realize the action of the material moving mechanism.
[0042] Preferably, the movable positioning fixture comprises a fixed base and a tightening slider slidably matched with the base, and the tightening slider is provided with a second positioning groove;
[0043] The movable positioning tool further comprises a telescopic mechanism, the fixed end of the telescopic mechanism is arranged on the base, and the free end of the telescopic mechanism is connected and transmission-matched with the tightening slider.
[0044] In the prior art, workpiece clamping is typically achieved through telescopic mechanisms, such as motor-driven screw assemblies and cylinder-driven telescopic rod assemblies. These drive methods are all based on electrical signals. However, significant vibrations are present in processing equipment, which can cause signal errors. Consequently, these signals cannot fully meet continuous process requirements, resulting in a low workpiece yield. The present invention, however, utilizes a cam structure, whereby a camshaft drives a second cam to achieve workpiece clamping. This provides high stability. Since the camshaft rotates continuously, the electrical signal only controls whether the camshaft rotates, effectively eliminating drive errors caused by vibrations in the processing equipment. Therefore, although the present invention also incorporates a telescopic mechanism, its purpose is not to provide greater clamping force during workpiece clamping, but rather to prevent the clamping slider from being properly reset. In other words, friction exists between the base and the clamping slider. Therefore, relying solely on the gravity of the clamping slider to slide cannot effectively meet the clamping slider's reset requirements. Therefore, utilizing the extension action of the telescopic mechanism prevents the clamping slider from being unable to continue moving due to friction, thereby better meeting the clamping slider's movement requirements.
[0045] Preferably, the movable positioning tool further includes:
[0046] A mounting seat, the mounting seat and the tightening slider are rotatably connected, and the mounting seat cooperates with the second cam; and
[0047] A tightening rod is provided along the motion path of the tightening slider, the tightening rod slidably engaging the tightening slider and / or the mounting seat, and a second reset member is sleeved on the tightening rod to deform and compress when the second cam pushes the movable positioning tooling;
[0048] Wherein, the second reset member is a cylindrical spring or a plurality of disc springs connected in positive and negative directions.
[0049] The reset member 2 can better assist the coordination between the movable positioning tooling and the fixed positioning tooling by releasing the elastic force when the driving mechanism drives the movable positioning tooling to move; it can be seen that the cylindrical spring and multiple disc springs connected in positive and negative directions can well meet this use requirement. For multiple disc springs connected in positive and negative directions, while having good elasticity, it has the advantages of easy installation and low space requirements.
[0050] Preferably, the tightening slider includes a connecting portion and a tightening portion 1, and the tightening portion 1 is inserted into the inner side of the connecting portion;
[0051] The tightening slider further includes a second tightening portion, the connecting portion is provided with a connecting step, the second tightening portion is connected to the first tightening portion, and abuts against the connecting step of the connecting portion;
[0052] The first tightening part and the second tightening part are both provided with a second positioning groove.
[0053] Since the tightening part 1 is inserted into the inner side of the connecting part, and the tightening part 2 is connected to the tightening part 1 and abuts against the connecting step of the connecting part, the connecting part 2 is located on the upper side of the connecting part 1. Therefore, this structure is suitable for workpieces with a longer length, and this structure is conducive to reducing the assembly accuracy of parts and facilitating structural assembly.
[0054] Preferably, the fixed positioning tool comprises a tool body, a retreat piece and a spring, wherein the retreat piece is arranged on the upper side of the first positioning groove, the retreat piece and the tool body are hinged, one end of the spring is connected to the retreat piece, and the other end is connected to the tool body;
[0055] The tightening mechanism moves toward the first positioning groove to push the workpiece into the first positioning groove, and the workpiece pushes the retreat plate to deform the spring under force, and the tightening mechanism moves away from the first positioning groove, and the spring unloads the force and resets, so that the retreat plate pushes the workpiece out of the first positioning groove.
[0056] Since there is friction between the workpiece and the feed track, and the positioning groove limits the workpiece, when the workpiece is processed, the workpiece may not be able to exit the processing station under the action of its own gravity. Therefore, the withdrawal plate and spring are used to ensure the movement of the workpiece after processing is completed, so that the workpiece can smoothly enter the next processing station or exit from the processing equipment.
[0057] Compared with the existing technology, the present invention can realize the tail processing of high-strength connected workpieces and improve process efficiency in an assembly line manner. It not only meets the processing requirements of a single workpiece and a single process, but also meets the processing requirements of multiple workpieces and multiple processes, reducing the overall processing time of the workpiece and at the same time ensuring the yield rate of the workpiece.

DETAILED DESCRIPTION
[0077] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.
[0078] like Figures 1 to 18 As shown, a bolt tail integrated processing equipment includes a feed track, at least one processing station is arranged along the feed track, the feed track includes a track 1 27 and a track 28, a material capacity gap 29 is formed between the track 1 27 and the track 2 28, the workpiece 5 moves in the material capacity gap 29, the feed track has a station track section 2, the station track section 2 and the processing station are arranged correspondingly, in the station track section 2, the position of the track 1 27 relative to the horizontal plane is higher than the track 2 28, so that the workpiece 5 moves along the feed track inclined to the horizontal plane, and the workpiece 5 is processed in each processing station in turn along the feed track; any processing station A clamping mechanism and a processing mechanism 4 are provided at the position, the clamping mechanism includes a fixed positioning tool and a movable positioning tool arranged relatively to each other, a part of the fixed positioning tool is configured as a feed track, the fixed positioning tool is provided with a positioning groove 1 6, and the movable positioning tool is provided with a positioning groove 2 8. When the workpiece 5 moves to the processing station, the movable positioning tool clamps the workpiece 5 between the positioning groove 1 6 and the positioning groove 2 8, so that the processing mechanism 4 processes the workpiece 5; the movement direction of the clamping mechanism is parallel to the conveying surface of the feed track inclined relative to the horizontal plane, and the processing axis of the processing mechanism 4 is perpendicular to the movement direction of the clamping mechanism.
[0079] In the present embodiment, a feeding mechanism is also included, and the workpiece 5 is transported to the feed track through the feeding mechanism. Since a part of the fixed positioning tool is configured as a feed track, it can be known that the workpiece 5 slides with its end to cooperate with the feed track to move to the processing station. When located at the processing station, the end of the workpiece 5 slides to cooperate with the fixed positioning tool. After the workpiece 5 moves to the processing station, the workpiece 5 mainly contacts the rail surface on the lower side (track 2 28), and the upper side of its position is the position of the positioning groove 1 6. Therefore, the workpiece 5 can be pushed into the positioning groove 1 6 by the pushing of the movable positioning tool, and in this process, the positioning groove 1 6 and the positioning groove 2 8 can also be used to clamp the workpiece 5. In the present embodiment, the processing station can realize at least one of chamfering, punching, squaring, and chip removal. For the convenience of explanation, there are four processing stations in the present embodiment, namely processing station 1, processing station 2, processing station 3, and processing station 4. Figures 1 to 5 As shown, the workpiece 5 output from the feeding mechanism passes through the feeding track and passes through the processing station 1, processing station 2, processing station 3, and processing station 4 in sequence. The processing station 1, processing station 2, processing station 3, and processing station 4 all have corresponding clamping mechanisms and processing mechanisms 4 to perform different process processing on the workpieces 5 in the four stations respectively to meet the actual processing requirements of the workpiece 5. Specifically, the first workpiece 5 enters the processing station 1 for processing. After completion, it exits from the processing station 1 and enters the processing station 2. At this time, the second workpiece 5 enters the processing station 1 for processing. Then the first workpiece 5 exits from the processing station 2 and enters the processing station 3. The second workpiece 5 exits from the processing station 1 and enters the processing station 2. At this time, the third workpiece 5 enters the processing station 1. Therefore, through such a continuous processing technology, the processing station 1, processing station 2, processing station 3, and processing station 4 can realize the simultaneous processing of four workpieces 5 in the continuous process. Furthermore, there can also be workpieces 5 waiting to be processed in the transition track section 3. Therefore, when this embodiment has multiple processing stations, it can provide good processing efficiency of the workpiece 5. It can be seen that multiple processing stations are usually configured for different processing technologies to better improve the processing efficiency and accuracy of the workpiece 5. Since the position of the track 1 27 relative to the horizontal plane is higher than that of the track 2 28 in the work station track section 2, when the movable positioning fixture moves away from the fixed positioning fixture, the workpiece 5 can be disengaged from the positioning groove 1 6, so that the workpiece 5 can more smoothly enter the next process stage or exit from the processing equipment. It should be noted here that the track surfaces of the track 1 27 and the track 2 28 can be parallel to the horizontal plane. At this time, due to the height difference between the track 1 27 and the track 2 28, the conveying surface formed by the two is inclined to the horizontal plane. Of course, the track surfaces of the track 1 27 and the track 2 28 can be located in the same plane. In this case, the plane is inclined to the horizontal plane, and thus the conveying surface is also inclined to the horizontal plane.
[0080] like Figure 8 、 Figure 10 As shown, in order to better achieve the clamping of the workpiece 5, the fixed positioning fixture is further provided with a posture adjustment member 7, which cooperates with the end surface of the workpiece 5 to keep the axis of the workpiece 5 in the positioning groove 1 6 coincident with the processing axis of the processing mechanism 4. The posture adjustment member 7 is located on the upper side of the positioning groove 1 6 and is used to cooperate with the end surface of the workpiece 5. Due to the structural characteristics of the workpiece 5, when the positioning groove 1 6 and the positioning groove 2 8 clamp the workpiece 5, the axis of the workpiece 5 may not coincide with the processing axis of the processing mechanism 4, and thus the preset processing requirements cannot be completed for the workpiece 5. After the posture adjustment member 7 is set, the plane where the end of the workpiece 5 is located is parallel to the contact plane of the posture adjustment member 7, thereby ensuring that the axis of the workpiece 5 is parallel to the processing axis of the processing mechanism 4. After the positioning groove 1 6 and the positioning groove 2 8 complete the clamping of the workpiece 5, it can be ensured that the axis of the workpiece 5 coincides with the processing axis of the processing mechanism 4, thereby better meeting the positioning processing requirements. Furthermore, when the workpiece 5 is located in the positioning groove 1 6, the bottom surface of the posture adjustment member 7 covers an area of the end surface of the workpiece 5 that is no more than 1 / 2 of the end surface area of the workpiece 5. This structure is beneficial to avoid damage to the end surface of the workpiece 5 during the process of correcting the machining posture of the workpiece 5. It should be emphasized that, if Figure 8 As shown, since the workpiece 5 has a "top-heavy" structure and the end is in contact with the feed track, the axis of the workpiece 5 has a force tending to be perpendicular to the horizontal plane. At this time, the end surface of the workpiece 5 will offset the force of its axis tending to be perpendicular to the horizontal plane due to the bottom surface of the posture adjustment member 7, thereby further achieving complete contact between the end surface of the workpiece 5 and the bottom surface of the posture adjustment member 7. This contact state is a semi-attached complete contact, which means that in the radial projection of the workpiece 5, the end surface of the workpiece 5 and the bottom surface of the posture adjustment member 7 partially overlap. In other words, they can also completely overlap, but in order to avoid damage to the workpiece 5, only a portion of them overlap. As a preferred embodiment, the bottom surface of the posture adjustment member 7 covers an area of the end surface of the workpiece 5 that is 2 / 5 of the end surface area of the workpiece 5.
[0081] Further, if Figure 10 As shown, the fixed positioning fixture has an adjustment mechanism for adjusting the relative position between the posture adjustment member 7 and the positioning groove 6. The adjustment mechanism can realize the displacement of the fixed positioning fixture in a preset Cartesian coordinate system, thereby making adaptive adjustments for different types of workpieces 5, ensuring that each type of workpiece 5 can meet the preset processing requirements. Furthermore, in this embodiment, in order to ensure that the workpiece 5 can exit from the positioning groove 6, especially when the workpiece 5 moves along a path parallel to the horizontal plane in the work station rail section 2, it is necessary to provide a force on the workpiece 5 to ensure that the workpiece 5 can be received by the push top portion 34 of the material transfer sheet 9, as shown in FIG. Figure 10As shown, the fixed positioning tool includes a tool body 21, a retreat piece 22 and a spring 23. The retreat piece 22 is arranged on the upper side of the positioning groove 6. The retreat piece 22 and the tool body 21 are hinged. One end of the spring 23 is connected to the retreat piece 22, and the other end is connected to the tool body 21; the tightening mechanism moves close to the positioning groove 6 to push the workpiece 5 into the positioning groove 6, and the workpiece 5 pushes the retreat piece 22 to make the spring 23 deform under force, and the tightening mechanism moves away from the positioning groove 6, and the spring 23 unloads the force and resets, so that the retreat piece 22 pushes the workpiece 5 out of the positioning groove 6. The positioning groove 6 is arranged on the tooling body 21, the posture adjustment part 7 is arranged on the upper side of the positioning groove 6, and the retreat piece 22 is movably arranged between the positioning groove 6 and the posture adjustment part 7; the adjustment mechanism in this embodiment includes an X-axis mechanism 24, a Y-axis mechanism 25 and a Z-axis mechanism 26 set based on the Cartesian coordinate system. In order to ensure the posture stability of the workpiece 5, it is obvious that the positions of the posture adjustment part 7 and the positioning groove 6 are set correspondingly. Therefore, when adjusting the relative position of the posture adjustment part 7 and the positioning groove 6, it is generally achieved through the Z-axis mechanism 26 (up and down direction), while the X-axis mechanism 24 (left and right direction) and the Y-axis mechanism 25 (front and back direction) can realize the position adjustment of the Z-axis mechanism 26. Furthermore, in this embodiment, in order to drive the workpiece 5 to efficiently exit the positioning groove 6, when the workpiece 5 enters the positioning groove 6, the workpiece 5 pushes the retreat piece 22. At this time, the spring 23 is deformed by the force, and has a tendency to push the workpiece 5 out of the positioning groove 6. Since the workpiece 5 is limited by the positioning groove 28, the spring 23 will maintain the existing position and posture. When the movable positioning tool moves away from the fixed positioning tool, that is, the positioning groove 28 and the positioning groove 6 are separated, the workpiece 5 is released from the restriction. At this time, the spring 23 unloads the force and resets. Its restoring force will drive the retreat piece 22 to move. Therefore, the retreat piece 22 can transmit the restoring force of the spring 23 to the workpiece 5, thereby driving the workpiece 5 to exit the positioning groove 6, thereby ensuring the smoothness of the processing technology.
[0082] like Figure 4As shown, in this embodiment, the feeding mechanism includes a loading rail 1, and the feeding rail also has a transition rail section 3 that cross-connects with the work station rail section 2, and the workpiece 5 enters the work station rail section 2 from the transition rail section 3; the work station rail section 2 is correspondingly arranged to the processing station; the loading rail 1 is connected with the first work station rail section 2 close to the feeding mechanism, that is, the loading rail 1 is configured as the first transition rail section 3. In this embodiment, the position of the loading rail 1 is not lower than the position of the work station rail section 2, and any two adjacent work station rail sections 2 are connected by the transition rail section 3. Along the movement path of the workpiece 5, the position of the previous work station rail section 2 is higher than the position of the next work station rail section 2. When the workpiece 5 moves on the loading track 1 and the feeding track, it can move in a downward manner throughout the entire process, especially at the connection between the loading track 1 and the feeding track, that is, the connection between the loading track 1 and the first station track section 2 near the feeding mechanism, the height difference between the two is not less than 0.5mm. In other words, in the loading track 1 and the first station track section 2 near the feeding mechanism, the end of the loading track 1 is not less than 0.5mm higher than the station track section 2. The step-by-step descent prevents the workpiece 5 from sliding and getting stuck. In other words, there is a height difference between the adjacent transition track sections 3 and the station track sections 2 to better achieve the movement of the workpiece 5. In this embodiment, when the transition track section 3 between the two station track sections 2 is an arc-shaped structure, it is more conducive to the sliding of the workpiece 5.
[0083] If the workpiece 5 is transferred in a full-length sliding manner, problems may arise, such as the difficulty of setting up the clamping mechanism and the processing mechanism 4, and the processing accuracy cannot be fully met. Therefore, in order to avoid these problems, the workpiece 5 moves along a path parallel to the horizontal plane in the station rail segment 2. Therefore, when the workpiece 5 is located in the station rail segment 2, a material transfer mechanism is required to realize the displacement of the workpiece 5. Specifically, Figure 5 、 Figure 6 As shown, as shown, it also includes a material moving mechanism, which includes a material moving piece 9 that can be switched between a first position and a second position, and the material moving piece 9 drives the workpiece 5 to move so that the position of the workpiece 5 is switched. At this time, it is equivalent to forming a work station track section 2 between the material moving piece 9 and the fixed positioning fixture, and the workpiece 5 falls from the loading track 1 onto the material moving mechanism, so that during the action of the material moving mechanism, the workpiece 5 is moved to the first position. At the same time, during the action of the material moving mechanism, the workpiece 5 in the first position can also be driven to the second position. It can be seen that the material moving piece 9 is used to achieve at least one of the following: transferring the workpiece 5 in the previous work station track section 2 to the transition track section 3, and transferring the workpiece 5 in the transition track section 3 to the next work station track section 2. It is known that the material moving piece 9 can push the workpiece 5 to move in the feed track.
[0084] Specifically, such as Figure 6As shown, the material transfer piece 9 is provided with a receiving portion 33. When the material transfer piece 9 is in the first position, the material transfer piece 9 carries the workpiece 5 through the receiving portion 33, so that when it switches to the second position, the workpiece 5 is transferred to the processing station; and / or, the material transfer piece 9 is provided with a pushing top portion 34. When the material transfer piece 9 is in the first position, the pushing top portion 34 avoids the positioning groove 1 6. When the workpiece 5 exits the positioning groove 1 6, the workpiece 5 and the pushing top portion 34 cooperate, and the material transfer piece 9 switches to the second position to transfer the workpiece 5 out of the processing station. The material transfer piece 9 in this embodiment is provided with a receiving portion 33 and a pushing top portion 34 at the same time. The receiving portion 33 is a notch structure, located in the middle of the material transfer piece 9, and matches the shape of the rod portion of the workpiece 5. The pushing top portion 34 is a stepped structure, located at the end of the pushing top portion 34. The workpiece 5 can also be matched through the range area of the stepped structure. When used specifically, the two adjacent front and rear workpieces 5 are respectively workpiece 1 and workpiece 2. Workpiece 1 and workpiece 2 slide to the end of the loading track 1 in sequence, the material moving piece 9 is in the first position, workpiece 1 is received by the receiving portion 33, and workpiece 2 still stays at the end of the loading track 1 and slides to the position of the previous workpiece 1, waiting for the receiving portion 33 to receive it next time; then the material moving piece 9 switches to the second position, so that the receiving portion 33 corresponds to the positioning groove 1 6, and then the movable positioning tool moves, pushing the workpiece 5 into the positioning groove 1 6, and using the positioning groove 2 8 to cooperate with the positioning groove 1 6 to clamp and position the workpiece 5, and then the tail of the workpiece 5 is processed, and at the same time The material transfer piece 9 returns to the first position and receives the second workpiece through the receiving portion 33; after the processing is completed, the movable positioning fixture moves away from the fixed positioning fixture, and the workpiece 1 is separated from the positioning groove 1 6 and received by the pushing portion 34. At this time, the material transfer piece 9 is switched from the first position to the second position. At this time, the workpiece 1 transitions from the station rail segment 2 to the transition rail segment 3, and then slides to the next station rail segment 2, and is received by the receiving portion 33 of the next material transfer piece 9. At the same time, the workpiece 2 is located at the processing station, thereby repeating the above-mentioned processing technology to achieve multiple process processing of multiple workpieces 5. Therefore, it can be seen that in this embodiment, if Figure 3 As shown, the material transfer piece 9 is connected as a work station rail segment 2 between the loading rail 1 and the transition rail segment 3, or between the previous transition rail segment 3 and the next transition rail segment 3, thereby realizing the stable displacement and processing of the workpiece 5 on the basis of realizing the function of the feeding rail.
[0085] As can be seen from the above, in this embodiment, a plurality of processing stations connected in series are provided on the material conveying track, and a material moving mechanism is provided on one side of each processing station. The material moving mechanism moves along the arrangement direction of the processing stations, and is used to move the workpiece 5 into or out of the processing station. The material moving mechanism and the movable positioning fixture are driven by different driving mechanisms, or the material moving mechanism and the movable positioning fixture are driven by the same driving mechanism. In order to provide mechanism linkage and avoid electrical signal errors caused by processing vibration, the material moving mechanism and the movable positioning fixture are driven by the same driving mechanism. Specifically, as Figure 1 、 Figure 5 、 Figure 9 As shown, the driving mechanism includes a camshaft 10 and a reset member 11; the camshaft 10 extends along the arrangement direction of the processing stations, and has a cam 12 that cooperates with the connecting rod mechanism, and a cam 2 13 that cooperates with the movable positioning fixture; the reset member 11 is used to drive the material shifting mechanism to reset. The cam 12 drives the material shifting mechanism to directly move linearly to achieve position switching, similar to the cam 2 13. However, in order to minimize the overall volume of the processing equipment, since there can be multiple cams 2 13, the displacement direction of the material shifting mechanism is best consistent with the axial direction of the camshaft 10. Based on this, the cam 12 can drive an intermediate mechanism to swing, and then convert the swing into the linear motion of the material shifting mechanism, thereby effectively reducing the volume of the equipment. In other words, the rotation of the cam 12 is converted into the swing of the intermediate mechanism, and then converted into the linear motion of the material shifting sheet 9. Generally, the rotation of the cam 12 can realize the movement of two material transfer pieces 9. In the case of four processing stations in this embodiment, the movement of four material transfer pieces 9 is required. At this time, the material transfer pieces 9 are grouped in pairs, and each group of material transfer pieces 9 is driven by the same camshaft 10. The two camshafts 10 can be connected by a belt, chain or gear transmission. Figure 6 、 Figure 11As shown, further, the material moving mechanism includes a sliding seat 14 and a fixed seat 15, the sliding seat 14 and the fixed seat 15 are slidably matched, and brackets 16 are provided at both ends of the sliding seat 14, and the brackets 16 at both ends of the sliding seat 14 correspond to two processing stations respectively; the material moving mechanism also includes a power rod 17, the power rod 17 can swing along a hinge point, the power rod 17 is connected to the sliding seat 14, and the power rod 17 and the cam 12 are slidably matched. In some embodiments, the reset member 11 is set between the fixed seat 15 and the bracket 16, and in this embodiment, the reset member 11 is set at the hinge point of the power rod 17. The above-mentioned intermediate mechanism is the power rod 17; the material moving piece 9 is connected to the bracket 16, and further, the material moving piece 9 can be adjusted in position on the bracket 16 using a slide groove slider structure. The processing equipment comprises a frame structure (not shown), to which a power rod 17 can be hinged. Furthermore, one side of one bracket 16 is connected to the sliding seat 14, and the other side is provided with a follower base 45. The follower base 45 is provided with a slideway 43 perpendicular to the sliding direction of the sliding seat 14, and a follower 46 is provided in the slideway 43, which slides in engagement with the follower. The power rod 17 is provided with a slideway 44 along its axis, and the follower 46 also slides in engagement with the slideway 44. Thus, when the power rod 17 swings, the follower 46 moves along the slideway 43 and the slideway 44, converting the swing of the power rod 17 into a linear displacement drive of the sliding seat 14. Furthermore, to further improve the driving stability of the camshaft 10, the power rod 17 includes a wheel body 1 that engages with the cam 1 12, and the tightening mechanism includes a wheel body 2 that engages with the cam 2 13. In other embodiments, the sliding seat 14 is provided with a follower base 45.
[0086] In this embodiment, the reset member 11 is a torsion spring, disposed at the hinge point of the power rod 17. When the protrusion of cam 12 engages with wheel body 1, the material shifter 9 is in the first position. At this time, the reset member 11 is deformed by the force. When the protrusion of cam 12 disengages from wheel body 1, the reset member 11 unloads the force and deforms, thereby pulling the sliding seat 14 to slide relative to the fixed seat 15, thereby switching the material shifter 9 from the first position to the second position. It can be seen that the contact section between the protrusion of cam 12 and wheel body 1 has a stable portion, and the two ends of the stable portion have smooth portions, thereby improving the driving stability and smoothness of cam 12.
[0087] like Figure 7As shown, in this embodiment, the movable positioning fixture includes a fixed base 18 and a clamping slide 19 that slides with the base 18, and the clamping slide 19 is provided with a positioning groove 28; the movable positioning fixture also includes a telescopic mechanism 20, the fixed end of the telescopic mechanism 20 is provided on the base 18, and the free end of the telescopic mechanism 20 is connected to the clamping slide 19. The base 18 is fixed to the frame structure. As for the clamping mechanism, the driving of the movable positioning fixture is achieved by a mechanical mechanism. Specifically, the movement of the camshaft 10 drives the cam 2 13 to rotate, so that the cam 2 13 and the clamping slide 19 are connected by transmission to achieve the pushing of the clamping slide 19, thereby achieving the driving and clamping of the workpiece 5. It should be emphasized that the driving by the mechanical structure of this embodiment can avoid the influence of vibration on the signal error compared with the electric drive, thereby better improving the stability of the clamping workpiece 5. In the initial state, the telescopic mechanism 20 is in an extended state. When the cam 2 13 pushes the top clamping slider 19, the telescopic mechanism 20 contracts, thereby meeting the requirement that the top clamping slider 19 moves toward the fixed positioning tooling. When the top clamping slider 19 is reset, since its own gravity is insufficient to support the reset of the top clamping slider 19, the sliding efficiency of the top clamping slider 19 is improved by driving the telescopic mechanism 20 to extend, thereby better meeting the reset requirement. Therefore, the cam 2 13 can well realize the periodic drive of the top clamping slider 19, and at the same time, it can also realize the rapid retreat of the top clamping slider 19, thereby improving process efficiency. Figures 14 to 16As shown, in this embodiment, in order to better align the positioning groove 2 8 of the clamping slider 19 with the positioning groove 1 6 of the fixed positioning fixture (station rail section 2), the movable positioning fixture further includes a mounting seat 47 and a clamping rod 35 disposed along the motion path of the clamping slider 19. The mounting seat 47 is rotatably connected to the clamping slider 19 and engages with the cam 2 13. The clamping rod 35 slidably engages the clamping slider 19 and / or the mounting seat 47. The clamping rod 35 is provided with a reset member 2 36, which deforms and compresses when the cam 2 13 pushes against the movable positioning fixture. The reset member 2 36 is a cylindrical spring 23 or a plurality of disc springs connected in opposite directions. The wheel body 2 is disposed on the mounting seat 47. Nuts 1 and 2 are provided at each end of the clamping rod 35, respectively. Nut 1 is positioned at the clamping slider 19, and nut 2 is positioned at the end of the clamping rod 35 away from the clamping slider 19 to limit the reset member 2 36. In the initial state, when the telescopic mechanism 20 is in an extended state, the reset member 2 36 is compressed. Therefore, when the cam 2 13 pushes the clamping slider 19, the reset member 2 36 releases the stored energy, thereby assisting in pushing the clamping slider 19. Due to its shape characteristics, the disc spring provides greater elastic force in the same space than the cylindrical spring 23 and has the advantage of a compact structure. Therefore, this embodiment preferably uses multiple disc springs connected in opposite directions. When the cam 2 13 rotates to the far end, it is in a clamping state. Due to machining errors, the workpiece 5 is theoretically in an over-clamped state, which may cause the mechanism to jam. Therefore, the disc spring is used to preset the clamping force. When the workpiece 5 is over-clamped, the mounting seat 47 can compress the disc spring to eliminate the dimensional deviation. The reaction force generated by the mounting seat 47 when it is subjected to force cooperates with the disc spring to eliminate the over-clamping of the workpiece 5 caused by various deviations.
[0088] like Figure 15 、 Figure 16As shown, in this embodiment, the clamping slider 19 includes a connecting portion 37 and a first clamping portion 38. The first clamping portion 38 is inserted into the inner side of the connecting portion 37. The clamping slider 19 also includes a second clamping portion 39. The connecting portion 37 is provided with a connecting step 40. The second clamping portion 39 is connected to the first clamping portion 38 and abuts against the connecting step 40 of the connecting portion 37. Both the first clamping portion 38 and the second clamping portion 39 are provided with a second positioning slot 8. The connecting portion 37 is provided with a slot 41 to position the first clamping portion 38. After the first clamping portion 38 is properly positioned in the slot 41, the two are installed together using waist-shaped holes and fixing parts. For longer workpieces 5, the processing of the processing mechanism 4 may cause the workpiece 5 to tilt, so the second clamping portion 39 is required for further clamping. When the first tightening portion 38 and the second tightening portion 39 are connected, the installation method using only the first tightening portion 38 can actually meet the use requirements. However, the tightening force at this time will be transmitted to the fixing part in the waist-shaped hole, which is not conducive to the use of the fixing part. As a result, the second tightening portion 39 and the connecting step 40 are in conflict, and the force can be transmitted to the connecting portion 37 through the second tightening portion 39, thereby reducing or avoiding the reaction force of the fixed positioning tool on the fixing part. At this time, there can be a gap between the end of the first tightening portion 38 away from its positioning groove 2 8 and the end of the slot 41, which also effectively reduces the assembly accuracy of the parts and facilitates the assembly of the structure. According to actual conditions, the relative distance between the positioning groove 2 8 of the first tightening portion 38 and the positioning groove 2 8 of the second tightening portion 39 can also be adjusted.
[0089] like Figure 12 and Figure 13As shown, in order to better expand the application range of the processing equipment, the loading track 1 and the feeding track both include track 1 27 and track 2 28; the track 2 28 is connected to a power mechanism 30 for adjusting the relative position between track 1 27 and track 2 28. The power mechanism 30 adjusts the relative distance between track 1 27 and track 2 28, that is, the size of the gap. In this embodiment, the adjustment is achieved by a motor-driven cam mechanism in conjunction with a slide mechanism in a push-up manner. The workpiece 5 moves in the material gap 29. The spacing of the material gap 29 matches the diameter of the shaft of the workpiece 5 so that the end of the workpiece 5 can overlap on track 1 27 and track 2 28. Therefore, by adjusting the spacing of the material gap 29, it can adapt to workpieces 5 of different specifications and models to expand the scope of application. In addition, the feeding track is connected to a lifting mechanism 42 for adjusting the relative height of the feeding track. The lifting mechanism 42 can be realized by a screw, and can simultaneously lift and lower the track 1 27, the track 2 28, and the power mechanism 30. In this embodiment, the feed track has multiple sections, so it can be understood that each section can be adjusted. In order to keep the height of the feed track changed synchronously, the lifting mechanism 42 of each section of the feed track can realize synchronous power transmission through belts, gears, etc. It should be noted that, if Figure 1 As shown, the loading mechanism also includes a tray 31. Typically, the tray 31 vibrates to load the workpiece 5. The loading track 1 and the tray 31 of the loading mechanism can be adjusted in position using the same power source, eliminating the time required to adjust the tray 31 separately, thereby improving debugging efficiency. In addition, a drivable rail pressure plate 32 is provided on the loading track 1. The rail pressure plate 32 can prevent the workpiece 5 from entering the loading track 1. If a workpiece 5 is already in the loading track 1, the workpiece 5 can also be stopped by pressing the end of the workpiece 5.
[0090] It should be noted that, in this embodiment, the machining axis of the machining mechanism 4 can be adapted to different cutting tools or machining tools, so that at each machining station, processes such as chamfering the flat end face of the workpiece 5, machining center holes, machining blind holes, punching, and chip removal can be selectively implemented.
[0091] The above are merely preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention should be determined by the scope defined in the claims. Persons skilled in the art will appreciate that improvements and modifications may be made without departing from the spirit and scope of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention.
