Description

Technical Field

[0001] This invention relates to the field of machining and manufacturing equipment technology, specifically to a busbar cutting device with a positioning structure. Background Technology

[0002] In the processing of busbar trunking shells, U-shaped aluminum alloy profiles often need to be cut in both horizontal and vertical orientations to meet the requirements of subsequent end corner splicing. However, existing cutting equipment has the following significant drawbacks when positioning and clamping such U-shaped workpieces:

[0003] Firstly, when the workpiece is placed vertically, i.e., with the opening facing to the side, the upper and lower ends of the workpiece are suspended lateral supports. Existing clamping mechanisms can usually only apply strong pressure from the outside. This unidirectional force easily causes the lateral supports on both sides to shrink and deform inward, seriously affecting the cross-sectional dimensions and splicing accuracy.

[0004] Secondly, when the workpiece is placed horizontally, i.e., with the opening facing upwards, the bottom circular saw generates a huge reaction force as it cuts upwards. Existing mechanisms often struggle to penetrate deep into the U-shaped groove to apply direct downward pressure to the base plate, and the overhanging clamping component lacks vertical rigid support. This causes the clamping component to easily yield or vibrate when resisting the cutting force, resulting in the workpiece becoming loose and misaligned.

[0005] In summary, due to the drastically different force logics of these two placement postures, existing equipment struggles to simultaneously meet the dual requirements of preventing deformation during vertical cutting and resisting strong vibrations during horizontal cutting with a single clamping mechanism. Therefore, providing a positioning and clamping device that can adaptively accommodate different workpiece postures, deeply support the internal parts to prevent lateral shrinkage, and provide strong rigid support to resist cutting forces is a pressing technical challenge in this field. Summary of the Invention

[0006] Therefore, it is necessary to provide a busbar cutting device with a positioning structure to address the problems of existing technologies.

[0007] To solve the problems of the prior art, the technical solution adopted by the present invention is: a busbar trunking cutting device with a positioning structure, including a cutting machine table and a positioning component disposed on the cutting machine table;

[0008] The positioning assembly includes a positioning stop fixed to the cutting machine table, a vertical pressing component and a horizontal pushing component disposed on the cutting machine table, and a pressing mechanism. The positioning stop is rectangular, and its length direction is the feeding direction of the workpiece.

[0009] The pressing mechanism includes a translation frame and a combined pressing head. The translation frame is used to drive the combined pressing head to move closer to or away from the positioning stop along the width direction of the positioning stop.

[0010] The combined clamping head includes a housing, a trigger slider, and a fixed support block and a movable pressure block located above and below the trigger slider, respectively. The fixed support block is fixedly connected to the housing, and the movable pressure block is slidably connected to the housing in the vertical direction. The trigger slider is slidably connected to the housing in the direction of movement of the translation frame. The trigger slider and the movable pressure block are wedge-shaped to drive the movable pressure block to extend downward when the trigger slider slides into the housing.

[0011] The combined pressing head, the vertical pressing component, and the horizontal pressing component are all on the same vertical plane; the vertical pressing component is vertically adjustable and is used to press the workpiece downward or abut against the top of the fixed support block; the horizontal pressing component is telescopically adjustable along the moving direction of the translation frame, and the trigger slider is used to slide into the housing when pressed by the horizontal pressing component or the workpiece.

[0012] Furthermore, the cross-section of the housing is U-shaped, the trigger slider is disposed in the opening of the housing, guide pins are fixedly provided on both sides of the trigger slider, and guide grooves are provided on both sides of the housing. The length direction of the guide groove is parallel to the moving direction of the translation frame, and each guide pin is slidably engaged with the corresponding guide groove.

[0013] Furthermore, a bracket extending outward along the sliding direction of the trigger slider is formed on the side of the housing opposite to its opening. A columnar receiving groove is formed inward at one end of the trigger slider facing the bracket. The axial direction of the columnar receiving groove is parallel to the sliding direction of the trigger slider. A columnar slot is provided inside the trigger slider, which is coaxial with and communicates with the columnar receiving groove. The diameter of the columnar slot is smaller than the diameter of the columnar receiving groove, so that a step is formed between the two. A pin is fixed on the bracket and inserted coaxially into the columnar slot. A first spring is sleeved on the pin, and the two ends of the first spring abut against the bracket and the step, respectively.

[0014] Furthermore, both sides of the housing are formed with support blocks, and both sides of the movable pressure block are fixed with several vertically arranged limiting pins. Each limiting pin passes upward through the corresponding support block. The upper ends of several limiting pins located on the same side of the movable pressure block are fixedly connected by a connecting plate. Each limiting pin is fitted with a second spring, and the two ends of the second spring abut against the support block and the connecting plate, respectively.

[0015] Furthermore, the top surface of the movable pressure block includes a first horizontal pressure-bearing surface and a first inclined surface, and the bottom surface of the trigger slider includes a second horizontal pressure-bearing surface and a second inclined surface. The first inclined surface and the second inclined surface slide against each other to form the wedge surface fit. When the movable pressure block descends to the limit position, the second horizontal pressure-bearing surface slides above the first horizontal pressure-bearing surface and abuts against the first horizontal pressure-bearing surface.

[0016] Furthermore, the cutting machine table is equipped with a circular saw, and the cutting machine table is equipped with a horizontally arranged turntable. The circular saw can rotate together with the turntable. The turntable has a cutting groove for the circular saw to extend from bottom to top to cut the workpiece. The turntable is used to adjust the extension direction of the cutting groove by rotating, so that the extension angle of the cutting groove on the cutting machine table is adjustable. The angle between the length direction of the positioning stop and the length direction of the cutting groove constitutes the cutting angle of the circular saw on the workpiece.

[0017] Furthermore, taking the workpiece feeding direction as a reference, the pressing mechanism is located on the rear side of the cutting groove, and the positioning assembly also includes a limiting member located on the front side of the cutting groove. The limiting member is used to block and position the end of the workpiece that extends forward beyond the cutting groove. The limiting member includes a plurality of baffles spaced apart along the length direction of the positioning block. The positioning block has a plurality of strip-shaped receiving grooves on the side facing the workpiece that correspond one-to-one with the baffles. The baffles slide in the corresponding strip-shaped receiving grooves along the width direction of the positioning block, and the middle of the baffle is provided with an anti-slip block.

[0018] Furthermore, the positioning stop is fixedly provided with a plurality of guide rods spaced apart along its length direction, and the axial direction of each guide rod is parallel to the width direction of the positioning stop. The translation frame is fixedly provided with a plurality of sliding sleeves corresponding one to one of the guide rods, and each sliding sleeve is slidably sleeved on the corresponding guide rod. The cutting machine platform is fixedly provided with a translation cylinder whose output direction is parallel to the width direction of the positioning stop, and the translation frame is fixedly connected to the output end of the translation cylinder.

[0019] Furthermore, the vertical pressing component includes a lifting cylinder and a first abutting block. The lifting cylinder is vertically arranged and fixedly connected to the positioning stop, and the first abutting block is fixedly connected to the output end of the lifting cylinder.

[0020] Furthermore, the horizontal pressing component includes a pressing cylinder and a second abutting block. The pressing cylinder is horizontally arranged and fixedly connected to the positioning stop, and the output direction of the pressing cylinder is consistent with the translation direction of the combined pressing head. The second abutting block is fixedly connected to the output end of the pressing cylinder.

[0021] The beneficial effects of this invention compared to the prior art are:

[0022] This invention combines a pressing head with a vertical pressing component and a horizontal pushing component located on the same vertical plane, and can adaptively accommodate two cutting postures of U-shaped workpieces using only one pressing mechanism. When the workpiece is placed vertically, the combined clamping head extends into the workpiece, and the fixed support block lifts the inner wall of the upper side strip of the workpiece. At the same time, the side wall of the workpiece's bottom plate pushes against the trigger slider, causing the movable pressure block to press down. Combined with the downward pressure of the external vertical pressure component, an internal and external clamping support is formed at the lateral support strip above the workpiece, fundamentally preventing the lateral support strip from shrinking and deforming inward due to unidirectional strong pressure. When the workpiece is placed horizontally, the horizontal pushing component actively pushes the trigger slider to drive the movable pressure block to penetrate the opening and compact the workpiece's bottom plate. At the same time, the vertical pressure component presses down tightly against the top of the fixed support block, providing vertical rigid reinforcement support for the cantilevered combined clamping head. This greatly enhances the overall rigidity of the clamping mechanism, effectively resists the huge reaction force generated by the circular saw cutting from bottom to top, eliminates force yielding and vibration phenomena, and ensures the dimensional accuracy and stability of the workpiece processing.

[0037] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0038] like Figure 1 As shown, in the busbar trunking processing technology, the workpiece to be cut is usually a basic profile used for assembling the busbar trunking shell, such as an aluminum alloy component with a U-shaped cross-section. This type of workpiece involves two different cutting methods during processing: horizontal cutting when the workpiece is placed horizontally and vertical cutting when the workpiece is placed vertically. For example... Figure 2 and Figure 3As shown, the finished workpieces obtained through these two different cutting postures have different shapes. The ends of the horizontally cut workpieces are obliquely truncated, while the ends of the vertically cut workpieces are chamfered. These workpieces cut at specific angles are mainly used for subsequent bevel welding between each other to finally splice them into a complete aluminum alloy busbar casing. Generally speaking, the workpieces obtained by vertical cutting are relatively short, and the same basic profile will be cut at both ends and multiple times in actual processing to meet the perfect splicing requirements of complex casing shapes. The busbar cutting device with a positioning structure provided by this invention can be used to adaptively and stably clamp and fix such basic profiles when facing the above two cutting postures, and when the workpiece is placed vertically, it can effectively prevent the lateral supports on both sides of its U-shaped opening from shrinking and deforming inward due to external clamping force.

[0039] refer to Figures 4 to 13 The busbar trunking cutting device with a positioning structure shown includes a cutting machine base 1 and a positioning component mounted on the cutting machine base 1, which serves as the supporting foundation for the entire device. A circular saw is installed inside the cutting machine base 1, and a horizontally positioned turntable 24 is mounted on the cutting machine base 1. The circular saw rotates with the turntable 24, which has a cutting groove 25 for the circular saw to extend upwards from bottom to top to cut the workpiece. In actual operation, the circular saw is retracted into the cutting machine base 1 for concealment when not cutting; it is only driven to extend upwards from the cutting groove 25 to cut the workpiece when a cutting operation is performed. Furthermore, the turntable 24 is used to adjust the extension direction of the cutting groove 25 by rotation, so that the extension angle of the cutting groove 25 on the cutting machine base 1 is adjustable, thereby flexibly meeting the cutting requirements of different angle splicing joints. It should be noted that the above-described structure of the cutting machine base 1, which uses the turntable 24 to adjust the cutting angle and the lifting and extending / retracting of the circular saw, can be directly implemented using existing technology in the field; its main purpose is to provide a working environment for this invention.

[0040] To achieve precise guidance and length control of the workpiece during the feeding process, such as Figure 4 and Figure 6As shown, the positioning assembly includes a positioning stop 2 fixed to the cutting machine table 1. The positioning stop 2 is rectangular, and its length direction is the workpiece feeding direction, providing a straight and conforming guide reference for the workpiece's forward movement. The angle between the length direction of the positioning stop 2 and the length direction of the cutting groove 25 constitutes the cutting angle of the circular saw on the workpiece. Based on the workpiece feeding direction, the positioning assembly also includes a limiting member located in front of the cutting groove 25. The limiting member is used to block and position the end of the workpiece extending forward beyond the cutting groove 25, thereby precisely limiting the length of each cut. The limiting member includes several stop bars 26 spaced apart along the length direction of the positioning stop 2. The positioning stop 2 has several strip-shaped receiving grooves 27 corresponding to the stop bars 26 on the side facing the workpiece. The stop bars 26 slide within their corresponding strip-shaped receiving grooves 27 along the width direction of the positioning stop 2. The operator can pull out a specific stop bar 26 according to the required cutting length. An anti-slip block 28 is provided in the middle of the stop bar 26 to provide friction during pulling for ease of operation.

[0041] To further achieve a secure clamping of the workpiece after precisely defining its cutting length and position, such as... Figure 4 and Figure 5 As shown, the positioning assembly also includes a pressing mechanism mounted on the cutting machine base 1. The pressing mechanism includes a translation frame 3 and a combined pressing head 4. The translation frame 3 drives the combined pressing head 4 to move closer to or further away from the positioning stop 2 along its width direction, thereby moving closer to or away from the working area. To ensure the stability of the translation frame 3's movement, several guide rods 29 are fixedly mounted on the positioning stop 2, spaced apart along its length. The axial direction of each guide rod 29 is parallel to the width direction of the positioning stop 2. Several sliding sleeves 30, corresponding one-to-one with the guide rods 29, are fixedly mounted on the translation frame 3. Each sliding sleeve 30 is slidably mounted on its corresponding guide rod 29. A translation cylinder 31, with its output direction parallel to the width direction of the positioning stop 2, is fixedly mounted on the cutting machine base 1. The translation frame 3 is fixedly connected to the output end of the translation cylinder 31, and the translation cylinder 31 provides power to achieve the automated forward and backward movement of the translation frame 3. As the translation frame 3 delivers the carrier of the clamping action to above the workpiece, the basic structure inside the combined clamping head 4 located on the translation frame 3 begins to perform its positioning function.

[0042] In order for the combined clamping head 4 to adaptively respond to the support and clamping requirements of the workpiece under different placement postures, such as Figure 1 As shown, with the workpiece feeding direction as the reference, that is, along the length direction of the positioning stop 2, the pressing mechanism is located behind the cutting groove 25. Figure 7As shown, in terms of specific structure, the combined clamping head 4 uses the housing 5 as its basic frame. The cross-section of the housing 5 is U-shaped, forming an opening on one side. A trigger slider 6 is provided inside the opening of the housing 5. The trigger slider 6 is horizontally slidably connected to the housing 5 along the moving direction of the translation frame 3. To ensure the accuracy of this horizontal sliding, guide grooves 10 are provided on both sides of the housing 5. The length direction of the guide grooves 10 is parallel to the moving direction of the translation frame 3. Guide pins 9 are correspondingly fixed on both sides of the trigger slider 6. Each guide pin 9 slides in cooperation with the corresponding guide groove 10 to prevent the trigger slider 6 from deflecting when subjected to force.

[0043] To facilitate the support and clamping of the workpiece using the aforementioned main sliding frame, such as... Figure 7 and Figure 8 As shown, the combined clamping head 4 also includes a fixed support block 7 and a movable pressure block 8 respectively arranged on the upper and lower sides of the trigger slider 6. The fixed support block 7 is fixedly connected to the housing 5 and is mainly used to extend into the workpiece to provide support when the workpiece is placed vertically; the movable pressure block 8 is slidably connected to the housing 5 in the vertical direction and is used to extend downward and firmly press the workpiece when driven.

[0044] Within the structural basis of the combined clamping head 4, in order to accurately achieve the conversion of the movement direction and ensure the structural stability under the clamping state, such as Figure 7 and Figure 8 As shown, the trigger slider 6 and the movable pressure block 8 are engaged with a wedge-shaped surface, so that when the trigger slider 6 slides into the housing 5, the movable pressure block 8 can be driven to extend downward using the principle of inclined plane compression. Specifically, the top surface of the movable pressure block 8 includes a first horizontal bearing surface 20 and a first inclined surface 21, and the bottom surface of the trigger slider 6 includes a second horizontal bearing surface 22 and a second inclined surface 23. The first inclined surface 21 and the second inclined surface 23 slide in contact to form a wedge-shaped surface engagement. When the movable pressure block 8 is compressed and descends to its limit position, the second horizontal bearing surface 22 slides above the first horizontal bearing surface 20 and abuts against the first horizontal bearing surface 20, thereby providing rigid support in the vertical direction and preventing the inclined surface from being continuously worn by force.

[0045] To ensure that the trigger slider 6 automatically and smoothly returns to its initial state after the clamping operation is completed and the thrust is removed, in preparation for the next work cycle, such as... Figure 7 and Figure 8As shown, a bracket 11 extending outward along the sliding direction of the trigger slider 6 is formed on the side of the housing 5 opposite to its opening. A cylindrical receiving groove 12 is formed inward at the end of the trigger slider 6 facing the bracket 11, and the axial direction of the cylindrical receiving groove 12 is parallel to the sliding direction of the trigger slider 6. A cylindrical slot 13 is provided inside the trigger slider 6, coaxial with and communicating with the cylindrical receiving groove 12. The diameter of the cylindrical slot 13 is smaller than the diameter of the cylindrical receiving groove 12, so that a step is formed between the two. A pin 14 is fixed on the bracket 11 and inserted coaxially into the cylindrical slot 13. A first spring 15 is sleeved on the pin 14. The two ends of the first spring 15 abut against the bracket 11 and the step, respectively, for ejecting the trigger slider 6 outward after the external force is removed.

[0046] In addition to the reset structure of the trigger slider 6 mentioned above, in order to achieve automatic reset of the movable pressure block 8 in the vertical direction, such as... Figure 7 and Figure 8 As shown, support blocks 17 are formed on both sides of the housing 5, and several vertically arranged limiting pins 16 are fixed on both sides of the movable pressure block 8. Each limiting pin 16 slides upward through the corresponding support block 17. The upper ends of the several limiting pins 16 on the same side of the movable pressure block 8 are fixedly connected by a connecting plate 18. A second spring 19 is sleeved on each limiting pin 16, and the two ends of the second spring 19 abut against the top of the support block 17 and the bottom of the connecting plate 18, respectively. When the trigger slider 6 slides outward to retract and releases the wedge pressure on the movable pressure block 8, the second spring 19 uses its own elastic force to pull up the connecting plate 18 and the limiting pins 16, thereby pulling the movable pressure block 8 back to its initial position.

[0047] In order to precisely drive the combined clamping head 4 to handle different workpiece placement postures, such as Figure 9 and Figure 10 As shown, the positioning assembly also includes a vertical pressing component and a horizontal pushing component mounted on the cutting machine table 1. The combined pressing head 4, the vertical pressing component, and the horizontal pushing component are all located on the same vertical plane to ensure concentrated and balanced force. The vertical pressing component is designed for lifting and pressing the workpiece downwards or abutting against the top of the fixed support block 7. Specifically, the vertical pressing component includes a lifting cylinder 32 and a first abutting block 33. The lifting cylinder 32 is vertically positioned and fixedly connected to the positioning stop 2, and the first abutting block 33 is fixedly connected to the output end of the lifting cylinder 32. The horizontal pushing component is designed for telescopic movement along the direction of movement of the translation frame 3. The trigger slider 6 is used to slide into the housing 5 when pressed by the horizontal pushing component or the workpiece. Specifically, the horizontal pushing component includes a pushing cylinder 34 and a second abutting block 35. It should be noted that, to save space and protect the equipment, the positioning stop 2 has an installation groove for accommodating the pushing cylinder 34. The push cylinder 34 is horizontally installed in the mounting groove and fixedly connected to the positioning stop 2. The output direction of the push cylinder 34 is consistent with the translation direction of the combined pressing head 4. The second abutment block 35 is fixedly connected to the output end of the push cylinder 34.

[0048] In summary, to more clearly and intuitively demonstrate the collaborative operation of the various components of this invention in actual processing, we will now take two different placement postures of the workpiece on the cutting machine table 1 as examples to explain in detail its complete working logic:

[0049] When the workpiece is placed horizontally during cutting:

[0050] like Figure 4 , Figure 5 as well as Figure 9 , Figure 10 As shown, the workpiece is stably supported by the cutting machine table 1, with one side tightly fitted against the positioning stop 2, and its end blocked and positioned by the corresponding stop strip 26. At this time, the translation cylinder 31 drives the translation frame 3, together with the combined clamping head 4, to move towards the workpiece, while simultaneously controlling the pushing cylinder 34 to drive the second abutment block 35 to extend. When the trigger slider 6 abuts against the second abutment block 35, it will be forced to slide into the housing 5 due to the thrust, and then, through the internal wedge surface cooperation, precisely drive the movable pressure block 8 to extend downward, firmly pressing the bottom plate of the workpiece onto the cutting machine table 1. Subsequently, the lifting cylinder 32 drives the first abutment block 33 to descend, so that it abuts tightly against the fixed support block 7 at the top of the combined clamping head 4. Through this vertical rigid abutment, the combined clamping head 4, which is in a suspended stress state, is provided with strong vertical limiting and support reinforcement, thereby significantly enhancing the overall structural rigidity and stress strength of the combined clamping head 4, ensuring that it can effectively resist the huge cutting reaction force generated by the high-speed circular saw on the workpiece in subsequent processing operations.

[0051] When the workpiece is placed vertically for cutting:

[0052] It should be noted in advance that in conventional assembly line cutting operations, the dimensions of the workpiece to be processed are usually fixed. During initial installation and debugging, the combined clamping head 4 is designed to ensure that its top fixed support block 7 is precisely flush with the inner wall of the lateral support bar above the workpiece when it is placed vertically. If a different size workpiece needs to be used in actual production (e.g., the workpiece width becomes narrower, resulting in a lower overall height when placed vertically), the operator only needs to temporarily install a height-adjusting pad on the cutting machine table 1. By raising the workpiece, the inner wall of the lateral support bar above the workpiece is ensured to be flush with the fixed support block 7 again, thus meeting the prerequisite for smooth insertion. Furthermore, to further improve the reliability of clamping and prevent the fixed support block 7 and movable pressure block 8 from failing to effectively reach the interior of the upper and lower lateral support bars of the workpiece due to an excessively deep workpiece opening, extension pressure plates can be installed on the ends of the fixed support block 7 and movable pressure block 8 extending towards the workpiece in practical applications. The extension pressure plates can extend significantly into the opening of the workpiece, effectively increasing the contact area and contact length between the clamping mechanism and the interior of the lateral support bar of the workpiece.

[0053] After meeting the above baseline conditions, the actual operation is as follows: Figures 11 to 13 As shown, the back of the workpiece is aligned with the positioning stop 2. At this time, the system controls the pushing cylinder 34 to retract into the positioning stop 2 to make room. Subsequently, the translation cylinder 31 drives the combined pressing head 4 to move laterally and directly insert it into the opening of the workpiece. During the insertion process, thanks to the prior leveling adjustment, the top fixed support block 7 can smoothly slide into the bottom of the lateral support bar above the workpiece, forming an upward internal support; while the front end of the trigger slider 6 directly abuts against the inner wall of the back of the workpiece. As the combined pressing head 4 continues to advance forward, the reaction force of the inner wall of the workpiece forces the trigger slider 6 to retract inward, thereby driving the movable pressure block 8 to gradually extend downward during the translation process, pressing the lateral support bar below the workpiece from the inside. At the same time, the lifting cylinder 32 drives the first abutting block 33 to descend, tightly abutting against the top of the lateral support bar above the workpiece, applying a downward external stabilizing force. In this state, the inside of the workpiece is supported by the fixed support block 7 and the movable pressure block 8, while the outside is strictly restricted by the positioning stop 2 and the vertical pressing component. This ingenious combination of internal and external clamping perfectly prevents the lateral supports on both sides of the workpiece from shrinking and deforming inward due to the huge clamping force, thus ensuring extremely high cutting accuracy and product quality even under complex postures.

[0054] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
