Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of busbar processing equipment, and particularly relates to a busbar polishing and chamfering all-in-one machine. BACKGROUND

[0002] In the field of power equipment manufacturing, as a key component for power transmission, the machining surface quality of the busbar directly affects the safety and reliability of the equipment.

[0003] In the traditional busbar machining process, the polishing and chamfering of the end face and holes of the busbar are mostly dependent on manual operation, that is, the workers need to use handheld tools to repeatedly polish the busbar, which not only has high labor intensity and low efficiency, but also is significantly affected by the skill level of the operator, and problems such as uneven polishing roughness and chamfer size deviation are prone to occur, which leads to an increase in the contact resistance of the busbar connection and even causes safety hazards such as local overheating. In addition, manual polishing cannot guarantee the consistency of batch products, increasing the difficulty and cost of subsequent assembly.

[0004] In the prior art, although some busbar machining mechanical equipment has appeared, these devices have obvious limitations in functional design. For example, for polishing the circular holes and the end edges of the busbar, a step-by-step processing method is usually adopted: first, a special device is used to polish the circular holes, and then the tool is replaced to chamfer the end edges. This step-by-step operation not only frequently changes the tooling fixture, prolonging the machining cycle, but also requires manual intervention due to the process connection, resulting in low automation degree and difficult improvement of production efficiency. At the same time, the existing equipment often relies on manual adjustment of parameters for machining precision control, limiting the stability of the machining quality.

[0005] Therefore, the drawbacks of traditional manual polishing and step-by-step mechanical machining are increasingly prominent, and a new type of device that integrates polishing and chamfering functions and has high efficient automation characteristics is needed to solve the problems of low efficiency, uneven quality and manual dependence in busbar machining, and to promote the development of power equipment manufacturing towards intelligentization and precision.

Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Examples, such as Figures 1-12As shown, a busbar grinding and chamfering integrated machine includes a housing 1, with a housing plate 2 on top of the housing 1. Both sides of the housing plate 2 are equipped with lifting receiving mechanisms 3. These mechanisms can receive large batches of workpieces, ensuring their stable placement and facilitating subsequent workpiece handling. They can also receive finished workpieces and, in conjunction with the discharge conveyor belt 5, complete the workpiece removal. The machine is simple and convenient to operate, with strong functionality. From right to left, the outer sides of the two receiving mechanisms 3 are respectively equipped with an infeed conveyor belt 4 and a discharge conveyor belt 5. The infeed conveyor belt 4 receives... Workpieces that have undergone external processes such as cutting and drilling are transported to receiving mechanism 3. The discharge conveyor belt 5 receives workpieces placed on another receiving mechanism 3 and outputs the processed workpieces, achieving continuous workpiece transport and improving automation. A concave frame 6 with a concave design is installed on the outer box 1 of receiving mechanism 3, supporting the positions of the feeding conveyor belt 4 and the discharge conveyor belt 5 to ensure the stability of the equipment. A material holding mechanism 7 is installed on the box plate 2 located between the two receiving mechanisms 3, which can bear workpieces of different sizes and ensure their stable placement. The mechanism ensures the smooth grinding of round holes in the workpiece and allows for repositioning of the workpiece to facilitate chamfering. It combines workpiece clamping and repositioning functions to meet various usage requirements. A through slot 2a is provided in the box plate 2 corresponding to the round hole grinding mechanism 8. The round hole grinding mechanism 8 is located in the box 1 below the material holding mechanism 7, facilitating grinding of round holes in multiple positions on the workpiece. A stand 9 is provided on the box 1 behind the material holding mechanism 7, and a material handling mechanism 10 is located above the front of the stand 9. This mechanism can handle both loading and unloading of workpieces. The machine can reposition and adjust the workpiece after grinding to ensure the smooth implementation of chamfering, guarantee the comprehensive progress of processing, and improve the work process. A pressing mechanism 11 is set on the rear side of the upright frame 9, and a pressing table 12 is set on the box plate 2 located inside the upright frame 9. It can press the workpieces conveyed to the pressing table 12 by the material holding mechanism 7 to ensure the smooth implementation of chamfering. A low box 13 is set on the rear side of the box 1, and a chamfering mechanism 14 is set on the low box 13 to chamfer the end edge of the workpiece. In this way, the all-in-one machine combines the functions of round hole grinding and end edge chamfering to meet the processing needs. In the above process: the established receiving mechanism 3 can, on the one hand, receive a large batch of workpieces, ensuring the stability of their placement and providing convenient conditions for subsequent workpiece handling; on the other hand, it can receive finished workpieces and cooperate with the discharge conveyor belt 5 to complete the workpiece export. It is simple and convenient to operate and highly functional. The established material holding mechanism 7 can, on the one hand, support workpieces of different specifications and sizes, ensuring their placement stability and guaranteeing the smooth grinding of workpiece round holes; on the other hand, it can reposition the workpiece to ensure the smooth chamfering process. This mechanism combines workpiece clamping and workpiece repositioning functions to meet different usage needs. The established round hole grinding mechanism 8 facilitates multi-position round hole grinding on workpieces. The established chamfering mechanism 14 can chamfer the end edges of workpieces. Thus, the integrated machine combines round hole grinding and end edge chamfering functions to meet processing requirements. The established pressing mechanism 11 can press the workpieces conveyed to the pressing table 12 by the material holding mechanism 7 to ensure the smooth progress of the chamfering work. The established material handling mechanism 10 can, on the one hand, realize the loading and unloading of workpieces, and on the other hand, adjust the workpieces that have completed the grinding work to ensure the smooth realization of the workpiece chamfering work, ensure the comprehensive development of the processing work, and improve the work process. This device is reasonably designed, simple in structure, convenient to process, and integrates grinding and chamfering functions to realize the integration of busbar processing procedures. On the one hand, the grinding of busbar round holes and the chamfering of the end edges can be completed continuously on the same equipment, avoiding the interruption between processes and manual intervention, and ensuring the forming quality of workpieces in the batch production process, ensuring the consistency of processing quality. On the other hand, the equipment is equipped with automatic feeding, clamping and conveying functions to improve the work process and adapt to different processing needs, ensuring the continuity and stability of production and processing work, and meeting the usage requirements.

[0023] To receive materials conveyed by the feeding conveyor belt 4 and to carry processed workpieces for subsequent unloading, the receiving mechanism 3 includes a vertical plate 31 located on the outside of the housing 1. Vertical sliding rods 32 are arranged on the front and rear sides of the outer side of the vertical plate 31. A vertical slider 33 is arranged on the outer side of the vertical sliding rods 32, and a vertical shift frame 34 is arranged on the vertical slider 33. A vertical shift cylinder 35 is arranged on the lower outer side of the vertical plate 31, and its output end is connected to the inner side of the vertical shift frame 34. Specifically, the vertical shift frame 34 and the vertical slider 33 can be vertically adjusted relative to the vertical sliding rods 32, and the vertical shift cylinder 35 provides driving power. The upper part of the vertical shift frame 34 is used to receive the conveyed materials. Considering that this device is used in conjunction with the busbar processing production line, when a large batch of workpieces is conveyed, the workpieces are placed on the vertical shift frame 34, and then controlled... The receiving mechanism 3 is lowered to receive the next workpiece. Multiple workpieces can be placed on the receiving mechanism 3 to await subsequent processing. The receiving mechanism 3, which is close to the discharge conveyor belt 5, is used to receive workpieces after processing. It is positioned at a high position when receiving materials, so the material handling mechanism 10 does not need to be readjusted when resetting. When a workpiece is placed on the receiving mechanism 3, it is lowered to be flush with the discharge conveyor belt 5 for easy output. Of course, to facilitate workpiece output, one end of the discharge conveyor belt 5 can be placed below the vertical moving frame 34. The vertical moving frame 34 can have a slot. The vertical moving frame 34 moves the workpiece down until the lower end of the workpiece contacts the upper end of the discharge conveyor belt 5. Then the workpiece can be output and discharged under the action of the discharge conveyor belt 5, improving the work process.To facilitate the unloading mechanism 10 in unloading workpieces from the receiving mechanism 3 near the feeding conveyor belt 4, a limiting clamping mechanism 36 is provided on the box 1 located outside the right receiving mechanism 3. Two sets of limiting clamping mechanisms 36 are arranged in an L-shape on the adjacent sides outside the receiving mechanism 3. Each limiting clamping mechanism 36 includes a vertical plate 361, a limiting slide bar 362 on the vertical plate 361, and a limiting slide block 363 on the limiting slide bar 362. A limiting drive cylinder 364 is located at the end of the vertical plate 361, and its output end is connected to the limiting slide block 363. A limiting clamping block 365 is provided on the outer side of the limiting slide block 363. Specifically, multiple workpieces are placed on the receiving mechanism 3 in a layered manner. When clamping is required, the receiving mechanism 3 is controlled to move upwards until the uppermost workpiece is aligned with the limiting clamping block 365. Subsequently, the control limit drive cylinder 364 operates, causing the limit clamping block 365 to be placed at the outer end face of the workpiece, completing the temporary clamping of the workpiece. Of course, the operation of the transverse limit clamping mechanism 36 can drive the workpiece to move to the end face of the longitudinally arranged vertical plate 361, while the transverse limit clamping block 365 is placed at one end of the workpiece and applies pressure to it, temporarily stabilizing the workpiece. At this time, the control receiving mechanism 3 moves downward, and the picking and unloading mechanism 10 moves to a position close to the workpiece and clamps it, completing one picking action. The workpiece is then moved to the subsequent processing station. The operation is simple and convenient. As for the longitudinally established limit clamping mechanism 36, it is used to organize the position of the conveyed workpiece, ensuring that one end is perpendicular to the vertical plate 361, providing convenient conditions for subsequent material picking and meeting usage requirements.

[0024] To grind the circular hole in the workpiece, the circular hole grinding mechanism 8 includes a vertical lead screw moving assembly 81 mounted on the inner side of a housing 1 near the feed conveyor belt 4; a longitudinal lead screw moving assembly 82 mounted at the moving end of the vertical lead screw moving assembly 81; a transverse lead screw moving assembly 83 mounted at the moving end of the longitudinal lead screw moving assembly 82; and a transverse seat 84 mounted at the moving end of the transverse lead screw moving assembly 83. A grinding head 85 is mounted on the transverse seat 84. Specifically, the vertical lead screw moving assembly 81 can drive the grinding head 85 to move vertically up and down, allowing the grinding head 85 to grind the circular hole vertically. The longitudinal lead screw moving assembly 82 can drive the grinding head 85 to move and adjust longitudinally, thus achieving vertical grinding of the workpiece. The grinding of multiple circular holes upwards is achieved by the horizontal lead screw moving assembly 83, which drives the grinding head 85 to move and adjust horizontally, thus grinding multiple circular holes on the workpiece horizontally. The aforementioned lead screw moving assembly is a component in the prior art that uses a lead screw to move the equipment. Those skilled in the art can effectively understand its working principle and setting method, so it will not be described in detail here. The mutual cooperation between the various lead screw moving assemblies can cover all the circular holes opened on the workpiece, ensuring the comprehensiveness of the grinding work. Furthermore, the grinding head 85 generally includes a motor and a grinding roller set at the output end of the motor. It is driven by the motor to rotate and can perform comprehensive grinding of the circular holes, ensuring the grinding effect. Moreover, the circular hole grinding mechanism 8 can cover the circular holes opened at various positions on the workpiece, greatly improving the work process.

[0025] To ensure the smooth operation of production and processing, the material holding mechanism 7 includes transverse slide bars 71 mounted on the box plate 2 and positioned on both sides of the through groove 2a. A transverse slider 72 is mounted on the transverse slide bar 71, and a transverse sliding plate 73 is mounted on the transverse slider 72. A first pressing mechanism 15 is mounted on the transverse sliding plate 73. A stand 74 is mounted on one end of the box plate 2, and a longitudinal slide bar / slider assembly 75 is mounted on the stand 74. A longitudinal moving plate 76 is mounted on the longitudinal slide bar / slider assembly 75. A cylinder is mounted on the outer side of the stand 74 and connected to the longitudinal moving plate 76. When driving power is applied to it, it can... The longitudinal slide block assembly 75 is moved, and the longitudinal slide block assembly 75 extends out of the pressing mechanism 11 so that the end of the workpiece is adapted to be moved onto the pressing mechanism 11, thereby pressing the position of the workpiece to ensure its stability. A second pressing mechanism 77 is provided on one side of the longitudinal moving plate 76. The first pressing mechanism 15 and the second pressing mechanism 77 are arranged in a mirror image. Specifically, the first pressing mechanism 15 can be moved and adjusted in the lateral direction relative to the transverse slide block 71 to facilitate the adjustment of the distance between the first pressing mechanism 15 and the second pressing mechanism 77, thereby adapting to workpieces of different sizes and specifications. The high-performance device is designed for various applications. Specifically, for different batches of workpieces, the distance between the two clamping mechanisms is pre-adjusted. Then, the workpiece is clamped and placed onto the clamping mechanism using the loading / unloading mechanism 10, ensuring proper clamping and preventing displacement. After the circular hole inside the workpiece is ground, it needs to be moved towards the chamfering mechanism 14. This adjustment is achieved by driving the longitudinal moving plate 76, causing it to move on the longitudinal slide block assembly 75. During this adjustment process, the first clamping mechanism 15 disengages from the workpiece, and the second clamping mechanism 77 presses the workpiece firmly. Then, the workpiece is aligned with the longitudinal... The moving plate 76 moves backward in the longitudinal direction until the end of the workpiece moves onto the pressing mechanism 11. Of course, the upper end face of the pressing table 12 is flush with the lower end face of the workpiece to ensure the convenience of workpiece placement. After the chamfering work is completed on one side of the workpiece, the longitudinal moving plate 76 is reset and driven to its original position. Then, the first clamping mechanism 17 in the picking and placing mechanism 10 is used to reposition the end face of the workpiece. The above actions are repeated to complete the corresponding chamfering work. After the chamfering work is completed, wait for the picking and placing mechanism 10 to output the workpiece to the outside. This process is repeated to automatically realize the repositioning adjustment of the workpiece position and ensure the continuity of production and processing.

[0026] To ensure proper clamping of the workpiece and facilitate the smooth grinding of the circular hole, the first clamping mechanism 15 includes a fixed plate 151. The fixed plate 151 has first bearing seats 152 and second bearing seats 153 arranged vertically on both its front and rear sides. A rotating rod 154 is positioned between the two upper first bearing seats 152. A cylindrical movable seat 155 is mounted on the rotating rod 154. A convex strip is formed on the outer periphery of the rotating rod 154, and the movable seat 155 has a groove that matches the convex strip. This allows the movable seat 155 to not only move horizontally relative to the rotating rod 154 but also to rotate when the rotating rod 154 rotates, thus fulfilling different usage requirements. An L-shaped... The design includes a retaining plate 156, with a bidirectional lead screw 157 positioned between two second bearing seats 153 below. A lead screw nut 158 ​​is positioned on the outer side of the bidirectional lead screw 157. Above the lead screw nut 158 ​​is a limiting seat 159 with an L-shaped cross-section. The short side of the limiting seat 159 has a limiting groove 1591 that matches the moving seat 155. The long side of the limiting seat 159 corresponds to the retaining plate 156. An extension plate 1510 is positioned on the front side of the fixed plate 151, and a drive switching mechanism 16 is mounted on the extension plate 1510. Specifically, the moving seat 155 can be synchronously adjusted by the movement of the limiting seat 159 to accommodate workpieces of different sizes and ensure that the long side of the limiting seat 159 can be adjusted. The movable seat 155 is positioned on the lower end face of the workpiece. Furthermore, the movable seat 155 can rotate circumferentially with the rotating rod 154, causing the clamping plate 156 to rotate towards the limiting seat 159 and abut against the upper end face of the workpiece. The established drive switching mechanism 16 is used to switch the drive power, allowing the clamping mechanism to easily switch drive power according to different usage requirements. Specifically, for workpieces of different lengths, the drive switching mechanism 16 first applies drive power to the bidirectional lead screw 157. The rotation of the bidirectional lead screw 157 drives the lead screw nut 158 ​​to different positions longitudinally. Due to the bidirectional lead screw 157, the two lead screw nuts 158 on the same rod move in different directions but can be adjusted synchronously. The limiting seat 159 is positioned to fit the workpiece. When the limiting seat 159 moves with the rotation of the forward and reverse double-acting screw 157, the design of its limiting groove 1591 can drive the moving seat 155 to move and adjust relative to the rotating rod 154. In particular, the pressing plate 156 can correspond to the position of the limiting seat 159. After the position adjustment is completed, the control drive switching mechanism 16 switches the drive power, especially making it act on the rotating rod 154. When the workpiece is placed on the limiting seat 159, the control rotates the rotating rod 154 and drives the moving seat 155 to rotate synchronously until the pressing plate 156 abuts against the outer end face of the workpiece, completing the pressing of the workpiece position and ensuring the stability of its position, providing convenient conditions for the workpiece round hole grinding work.

[0027] To facilitate convenient switching of the driving power in the clamping mechanism, the drive switching mechanism 16 includes a mounting bracket 161 located on the outside of the extension plate 1510. A first bevel gear 162 is located on the outside of the rotating rod 154, and a second bevel gear 163 is located on the outside of the bidirectional lead screw 157. A drive shaft 166 is located above the mounting bracket 161, and a motor is installed outside the drive shaft 166 to receive the driving power. A connecting shaft 164 is sleeved on the lower outer side of the drive shaft 166 and slides vertically relative to it. A linear bearing is installed at the connection point between the connecting shaft 164 and the mounting bracket 161, allowing the lower end of the connecting shaft 164 to move vertically up and down relative to the mounting bracket 161, and also to... To allow rotation, a crossbar 1661 is provided on the outer side of the drive shaft 166. A keyway 1641 adapted to the crossbar 1661 is provided inside the connecting shaft 164. In this way, the connecting shaft 164 can slide relative to the drive shaft 166 under the use of the crossbar 1661 and the keyway 1641, and can also rotate with the drive shaft 166 when it rotates, meeting the usage requirements. A ring sleeve 165 is provided on the outer side of the connecting shaft 164 below the keyway 1641, which is fixedly connected to the connecting shaft 164. A double-bevel gear 167 is provided on the outer side of the connecting shaft 164 below the ring sleeve 165. A semi-circular limiting sleeve 168 is provided on the outer side of the ring sleeve 165, which is connected to the ring sleeve. The 165-phase sliding connection includes a lifting rod 169 on the outer side of the limiting sleeve 168 and a shifting drive cylinder 1610 on the outer side of the mounting bracket 161, with its output end connected to the outer end of the lifting rod 169. A through hole 161a is provided in the mounting bracket 161 corresponding to the installation position of the lifting rod 169. During use: when the upper rotating rod 154 needs to rotate, the upper half of the double-sided bevel gear 167 meshes with the lower side of the first bevel gear 162. The drive shaft 166 receives the driving power and acts on the connecting shaft 164, driving the double-sided bevel gear 167 to rotate together. This allows the rotating rod 154 to drive the pressing plate 156 to rotate, thus acting on the workpiece to complete the action. When the bidirectional lead screw 157 needs to be driven, the shift drive cylinder 1610 is controlled to operate, especially driving the lifting rod 169 and the limiting sleeve 168 to move, and acting on the connecting shaft 164, so that the connecting shaft 164 moves vertically relative to the drive shaft 166 until the lower half of the bidirectional bevel gear 167 meshes with the upper part of the second bevel gear 163. At this time, controlling the drive shaft 166 to rotate can apply the driving power to the bidirectional lead screw 157. Of course, controlling the drive shaft 166 to rotate in different directions can give the bidirectional lead screw 157 different driving power, thereby driving the moving seat 155 to be placed in different positions, which has strong functionality.

[0028] To facilitate the gripping and output of workpieces to be processed and workpieces after processing, and to ensure the continuity of the production process, the material handling mechanism 10 includes a transverse screw moving mechanism 101 located above the front side of the upright frame 9. A transverse moving plate 102 is provided at the moving end of the transverse screw moving mechanism 101. An L-shaped limiting block 103 is provided at the front side of the transverse moving plate 102. An L-shaped lifting block 104 is provided within the two limiting blocks 103. A vertical drive cylinder 105 is provided above the transverse moving plate 102, and its output end is connected to the lifting block 104. The lifting block 104 has both ends positioned inside the limiting blocks 103 and can slide vertically relative to them. During use, the set... A vertically driven cylinder 105 acts on the lifting block 104 to facilitate the vertical adjustment of the material handling mechanism 10, providing a prerequisite for the first clamping mechanism 17 and the second clamping mechanism 18 to clamp the workpiece. This facilitates the adjustment of the workpiece's position and ensures the smooth progress of subsequent production processes. Meanwhile, the horizontal lead screw moving mechanism 101 can adjust the horizontal position of the horizontal moving plate 102. In other words, the second clamping mechanism 18 on the right can transport the workpiece from the receiving mechanism 3 near the feeding conveyor belt 4 to the loading mechanism, while the workpiece on the holding mechanism 7 undergoes corresponding grinding and chamfering. The first clamping mechanism 17 on the left has two functions. One application is to clamp the workpiece placed on the feeding mechanism 7 that needs chamfering, and to adjust its horizontal position to ensure the smooth completion of the chamfering workpiece end edge, meeting the usage requirements. Another application is to clamp the workpiece after grinding and chamfering and place it towards the receiving mechanism 3 near the discharge conveyor belt 5 for convenient export of the processed workpiece. Simultaneously, the loading and unloading mechanism 10 can be adjusted laterally; that is, when the second clamping mechanism 18 outputs the processed workpiece from the feeding mechanism 7, the first clamping mechanism 17 can transport the incoming workpiece towards the feeding mechanism 7. The above equipment can operate synchronously, completing both workpiece loading and unloading. The operation is simple and convenient, and the functionality is strong. Further details: A horizontal plate 106 is provided above the lower side of the lifting block 104. A horizontal slide bar 107 is provided on the horizontal plate 106. A synchronous adjustment mechanism 108 is provided on the horizontal plate 106 between the two horizontal slide bars 107. The synchronous adjustment mechanism 108 includes a rotating shaft 1081. A rotating plate 1082 is provided on the outer side of the rotating shaft 1081. Connecting rods 1083 are provided at both ends of the rotating plate 1082. Specifically, to accommodate workpieces of different sizes, a cylinder is also provided on the lifting block 104 on one side of the horizontal plate 106. Its output end is connected to one side of the first transverse frame 171 in the first clamping mechanism 17. The operation of this cylinder can drive the first transverse frame 171 to move.The connecting rod 1083 of the synchronous adjustment mechanism 108 is connected to the clamping mechanism, especially the first transverse frame 171 in the first clamping mechanism 17, which provides driving power to the synchronous adjustment mechanism 108. That is, the connecting rod 1083 in the synchronous adjustment mechanism 108 receives the driving power and pulls the rotating plate 1082 to rotate relative to the rotating shaft 1081. The other end of the rotating plate 1082 acts on another connecting rod 1083, and then on the second clamping mechanism 18. In this way, the operation of the synchronous adjustment mechanism 108 can act on the first clamping mechanism 17 and the second clamping mechanism 18, so that it can move laterally. The synchronous adjustment of the position moves the workpiece to the geometric center of different sizes, ensuring the stability of subsequent clamping and facilitating the transport of the workpiece to different positions, thus meeting usage requirements. A first clamping mechanism 17 and a second clamping mechanism 18 are respectively arranged on the left and right sides of the horizontal slide bar 107 outside the synchronous adjustment mechanism 108. Specifically, the first clamping mechanism 17 integrates material clamping and repositioning functions, adjusting the workpiece to different positions. The second clamping mechanism 18 can load unprocessed workpieces. The cooperation of these equipment components results in a high degree of automation and ensures the continuity of production and processing.

[0029] To facilitate material clamping, ensure convenient material handling, and improve work efficiency, the first clamping mechanism 17 includes a first transverse frame 171 connected to a transverse slide bar 107. A first hollow rotating platform 172 is positioned below the first transverse frame 171. A first connecting frame 173 is located at the rotating end of the first hollow rotating platform 172. A first longitudinal rod 174 is located inside the first connecting frame 173. First rotary drive cylinders 175 are located on both sides of the first longitudinal rod 174. First clamping plates 176 are arranged vertically and alternately at the output end of the first rotary drive cylinders 175. There are two clamping plates 176, one above the other, positioned relative to the first rotary drive cylinder. The rotating end of cylinder 175 is a detachable fixed connection, and there is a certain gap between the upper and lower first clamping plates 176 to allow the workpiece to be placed inside. When the upper first clamping plate 176 approaches the workpiece, its lower end face abuts against the upper end face of the workpiece, controlling the first rotary drive cylinder 175 to rotate 45 degrees, causing the lower first clamping plate 176 to also rotate. The upper and lower first clamping plates 176 cooperate and are placed at the end of the workpiece, completing the clamping of its position, providing convenient conditions for the subsequent horizontal repositioning adjustment of the workpiece. Specifically, the main function of the established first clamping mechanism 17 is to clamp the workpiece on the material holding mechanism 7 and perform horizontal flipping processing to make its end edge adaptable. The corresponding chamfering and grinding work involves using the established synchronous adjustment mechanism 108 to control its operation, adjusting the first clamping mechanism 17 and the second clamping mechanism 18 to different positions, making them relatively close to the geometric center of the workpiece, especially suitable for workpieces of different sizes. After the workpiece on the feeding mechanism 7 completes the grinding of the round hole and the chamfering of one side edge, the first clamping mechanism 17 is controlled to operate, so that the lower end face of the upper first clamping plate 176 is flush with the upper end face of the workpiece. The output end of the first rotary drive cylinder 175 is controlled to rotate to adjust the position of the first clamping plate 176. The two first clamping plates 176 can clamp the end edge of the workpiece. Then, the first hollow rotary platform 172 is controlled to rotate. The movement allows the workpiece to be repositioned horizontally at its ends, such as clockwise or counterclockwise by 90° or 180°, to meet different usage requirements. After the workpiece's ends are chamfered, the first clamping mechanism 17 holds the workpiece, and under the operation of the pick-and-place mechanism 10, the processed workpiece is placed onto the receiving mechanism 3 near the discharge conveyor belt 5 for convenient workpiece removal. Furthermore, the second clamping mechanism 18 includes a second transverse frame 181 connected to a transverse slide bar 107. A second connecting frame 182 is located below the second transverse frame 181, and a second longitudinal rod 183 is located inside the second connecting frame 182. Second rotary drive cylinders 184 are located on both sides of the second longitudinal rod 183.The output end of the second rotary drive cylinder 184 is equipped with a second clamping plate 185 arranged in a vertically staggered pattern. The second clamping mechanism 18 and the first clamping mechanism 17 are set up and operate on the same principle, except that the second clamping mechanism 18 does not have a rotation adjustment function. That is, after it is adjusted to a suitable position by the synchronous adjustment mechanism 108, it controls the second rotary drive cylinder 184 to rotate, so that the second clamping plate 185 clamps the end edge of the workpiece. Then, it controls the pick-and-place mechanism 10 to run, placing the clamped material onto the holding mechanism 7, thus facilitating subsequent processing and improving the practicality of the device to meet different usage needs.

[0030] To ensure the smooth operation of the workpiece edge chamfering, the pressing mechanism 11 includes concave limiting bars 111 located on the rear side of the upright 9. A vertical sliding plate 112 is positioned between the two limiting bars 111. The vertical sliding plate 112 can slide vertically relative to the limiting bars 111, ensuring the pressing effect of the pressing mechanism 11 on the workpiece and improving the work process. A vertical drive cylinder 113 is installed on the upright 9 above the limiting bars 111, and its output end is connected to the vertical sliding plate 112. A pressing block 114 is installed below the vertical sliding plate 112 to press... The material platform 12 includes a support frame 121, and a platform 122 is provided above the support frame 121, corresponding to the pressure block 114. Specifically, after the workpiece is ground through the round hole, the material holding mechanism 7 conveys the workpiece to the rear until the end edge of the workpiece is placed on the platform 122. Then, the vertical movement drive cylinder 113 is controlled to run, which acts on the vertical movement slide plate 112 and drives the pressure block 114 to press down on the upper end surface of the workpiece, thereby pressing the end edge of the workpiece to ensure the smooth progress of the subsequent chamfering work. After the chamfering work is completed, the pressure block 114 is removed from the workpiece and waits for the next pressing.

[0031] To ensure the smooth operation of the chamfering process, the chamfering mechanism 14 includes a transverse lead screw moving mechanism 141 positioned above the low-position box 13. A transverse frame 142 is positioned above the moving end of the transverse lead screw moving mechanism 141. A vertical lead screw moving mechanism 143 is positioned on one side of the transverse frame 142. A vertical plate 144 is positioned at the moving end of the vertical lead screw moving mechanism 143. A longitudinal lead screw moving mechanism 145 is positioned on the vertical plate 144. A longitudinal plate 146 is positioned at the moving end of the longitudinal lead screw moving mechanism 145. The longitudinal plate 146 has a concave shape. Chamfering components 19 are arranged at an inclined configuration near the corner of the longitudinal plate 146 close to the pressure mechanism 11. Specifically, considering the varying end lengths of different workpieces, motion interference may occur during the operation of the chamfering mechanism 14. The upper half of the transverse frame 142 has the same shape as the longitudinal plate 146, which is particularly beneficial for ensuring smooth operation after the longitudinal... To facilitate the movement of the slider assembly 75 to the end, the operation of the transverse lead screw moving mechanism 141, the vertical lead screw moving mechanism 143, and the longitudinal lead screw moving mechanism 145 allows for convenient adjustment of the chamfering assembly 19 in three directions, bringing it closer to the end of the workpiece. This facilitates subsequent chamfering work. The aforementioned lead screw moving mechanisms are all existing components that utilize lead screws to move equipment; their working principles and setups are readily understood by those skilled in the art, and will not be elaborated further. Thus, the chamfering mechanism 14 can move the chamfering assembly 19 to different positions, especially close to the end edge of the workpiece, ensuring smooth processing. The transverse lead screw moving mechanism 141 moves and adjusts the chamfering assembly 19 along the workpiece end edge direction, ensuring comprehensive chamfering work and meeting usage requirements.

[0032] To effectively complete the chamfering process at the end edge of the workpiece, the chamfering assembly 19 includes a mounting plate 191 arranged at an angle and designed with a concave shape. An inclined slide bar 192 is provided on the outer side of the mounting plate 191, and an inclined sliding plate 193 is provided on the inclined slide bar 192. An inclined drive cylinder 194 is provided on one side of the mounting plate 191, and its output end is connected to the inclined sliding plate 193. A second hollow rotating platform 195 is provided on the inclined sliding plate 193, and a chamfering head 196 is provided on the rotating end of the second hollow rotating platform 195. Specifically, the inclined sliding plate 193 and the inclined slide bar 192 are existing known technologies, meaning that the inclined sliding plate 193, driven by the inclined drive cylinder 194, can... The relative tilting slider 192 slides, which can drive the chamfering head 196 forward and backward to approach the edge of the workpiece, realizing convenient control of the chamfering feed. For the second hollow rotary platform 195, its circumferential rotation can drive the chamfering head 196 to rotate together, so that the angle between the chamfering head 196 and the edge of the workpiece can be conveniently adjusted to meet different chamfering processing needs. The chamfering head 196 generally includes a chamfering drive motor and a chamfering cutter set at the end of the motor. In use, the rotation of the drive motor can act on the chamfering cutter to complete the corresponding chamfering work. People can also freely replace the chamfering cutter according to different usage needs, which can greatly improve the work process.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
