Description

Technical Field

[0001] This utility model belongs to the field of bar production technology, specifically relating to a bar end burr grinding machine. Background Technology

[0002] During the cutting, rolling, or forging of bar stock, defects such as oxide scale, burrs, and flash are easily formed at the ends. Burrs are hard and porous, and if they are not removed, they may peel off during subsequent transportation or processing, affecting the surface finish of the product, or even scratching operators, damaging surrounding equipment, or causing production line shutdowns. Therefore, it is necessary to deburr and grind both ends of the bar stock to reduce the risk of failure, ensure the dimensional accuracy of the ends meets the standards, and optimize the surface performance of the bar stock.

[0003] In existing technologies, deburring of bar ends mainly relies on grinding machines. After the bar is fixed by a fixing mechanism, a brush mechanism approaches the bar with a high-speed rotating steel brush until it contacts the bar end to perform the deburring operation. The main drawback is that the high-speed rotating steel brush can only contact and process one end of the bar. When grinding the other end of the bar, it is necessary to flip the bar so that the other end faces the steel brush, which increases the complexity of operation and reduces production efficiency. Furthermore, the fixing of the bar and the advancement of the steel brush are performed separately by independent drive mechanisms. If brush mechanisms are set at both ends of the bar grinding station, it will increase the number of drive mechanisms, resulting in increased equipment size, operating energy consumption, and control costs.

[0004] Secondly, the bar conveying mechanism generally adopts a transmission roller unit, which is driven by multiple rotating rollers to move the bar forward. If the bar rolls on the roller during the grinding process, it will affect the positioning of the bar and the fixed mechanism, which may lead to failure or affect the grinding efficiency of the bar. At the same time, since the grinding operation requires a certain amount of time and intermittent operation, the transmission roller unit needs to be started and stopped frequently, resulting in high energy consumption, high cost and easy damage. Utility Model Content

[0005] The present invention aims to at least partially solve one of the above-mentioned technical problems. The present invention provides a bar end burr grinding machine, which can improve the working efficiency of deburring both ends of the bar, reduce operating energy consumption and equipment costs.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A bar end burr grinding machine includes a support platform and a grinding mechanism. The grinding mechanism includes a first driving mechanism, a fixing member, and a grinding brush assembly. The first driving mechanism is used to drive the fixing member to reciprocate relative to the support platform. The fixing member is provided with a guide member. The grinding brush assembly includes at least two sets of slide rails, slide rods, brush bodies, and a second driving mechanism located on both sides of the support platform and arranged opposite to each other. One end of the slide rod is provided with an elastic member, and the other end of the slide rod is connected to the second driving mechanism. The slide rods arranged opposite to each other can cooperate with the guide members and move opposite to each other along the slide rails. The second driving mechanism is used to drive the brush body to rotate.

[0008] To further improve grinding efficiency and reliability, the positioning and fixing of the bar stock by the support platform and the fixing component can be further optimized. In a preferred technical solution, both the support platform and the fixing component are provided with a first slot.

[0009] To further simplify the movement of the slide bar and the guide member and improve operating efficiency, the layout of the moving direction of the fixing member and the slide bar, and the mating surface of the guide member and the slide bar can be further optimized. In a preferred technical solution, the moving direction of the fixing member and the slide bar is set perpendicularly, the guide member is provided with a first inclined surface, and the slide bar is provided with a second inclined surface that can cooperate with the first inclined surface.

[0010] To further simplify the grinding mechanism and reduce the time for the brush body to advance again, the travel of the slide bar can be further limited. In a preferred embodiment, the second drive mechanism is matched with the slide rail for limiting.

[0011] To further facilitate automated batch processing, improve the positioning of bars and fixtures, and enhance grinding efficiency, the preferred technical solution includes a conveying mechanism. The support platform is provided with a plurality of first slots, and the conveying mechanism is used to transfer bars between adjacent first slots.

[0012] To further adapt to intermittent grinding operations and avoid frequent start-stop of the conveying mechanism, which increases operating energy consumption and failure risk, in a preferred technical solution, the conveying mechanism includes a transfer component and a third drive mechanism. The transfer component is provided with a plurality of second slots, and the third drive mechanism is used to drive the second slots to rotate with the transfer component between adjacent first slots.

[0013] To further simplify the transportation mechanism, the third drive mechanism can be further optimized. In a preferred technical solution, the third drive mechanism includes a rotating main shaft, a driven shaft, two eccentric wheels, and two connecting members. The two eccentric wheels are eccentrically connected to the main shaft and the driven shaft, respectively. A connecting rod is movably connected between the two eccentric wheels. One end of the connecting member is eccentrically connected to the eccentric wheel, and the other end of the connecting member is connected to the transfer member.

[0014] To further facilitate automatic feeding and transfer and improve processing efficiency, the preferred technical solution includes a feeding trough located at one end of the conveying mechanism and arranged at an angle.

[0015] Compared with the prior art, the beneficial effects of this utility model are at least as follows:

[0016] (1) After the second driving mechanism of this utility model drives the brush body to rotate, the first driving mechanism drives the fixing member to move close to the support table and maintain it for a period of time. While squeezing the rod to make it fit tightly against the support table and fix the rod, the guide member drives the opposing sliding rod to move synchronously in opposite directions along the slide rail. During this period of time, the deburring and grinding work at both ends of the rod can be completed simultaneously, which solves the cumbersome problem of having to flip the rod over to grind the other end after grinding one end in the prior art, and effectively improves work efficiency.

[0017] (2) During the movement of the fixed part of this utility model, the opposing sliding rods are driven by the guide to move synchronously in opposite directions along the slide rail, or the sliding rods are automatically reset by the elastic part. This can reduce the driving mechanism, thereby reducing the size of the grinding machine, reducing the difficulty of controlling the grinding machine, the energy consumption of operation and the equipment cost. By further limiting the movement stroke of the sliding rod, the time consumption of the second advance can be reduced, and the grinding efficiency can be further improved.

[0018] (3) The conveying mechanism of this utility model drives the second slot to rotate with the transfer component between adjacent first slots through the third drive mechanism, which can support the bar to move progressively between two adjacent first slots, adapt to the intermittent operation of grinding, and further solve the problem of increased operating energy consumption and failure risk caused by frequent start and stop of the conveying mechanism. Multiple bars can be loaded at one time, and the entire process does not require manual continuous placement or removal of bars, which improves the convenience of operation and processing efficiency.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" or "several" means two or more, unless otherwise explicitly specified.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] To address the technical problems of existing technologies that require flipping the bar stock to remove burrs from the ends, resulting in cumbersome operation and low production efficiency, and the need to install brush mechanisms at both ends of the bar grinding station, which would increase the drive mechanism, leading to increased equipment size, operating energy consumption, and control costs, the following solutions are proposed. Figures 1-3 As shown, this is a preferred embodiment of the bar end burr grinding machine of the present invention. The bar end burr grinding machine includes a support platform 209 and a grinding mechanism 4. The grinding mechanism 4 includes a first driving mechanism 403, a fixing member 405, and a grinding brush assembly. The first driving mechanism 403 is used to drive the fixing member 405 to reciprocate relative to the support platform 209. The fixing member 405 is provided with a guide member 406. The grinding brush assembly includes at least two sets of slide rails 402, slide rods 409, brush bodies 4011, and a second driving mechanism 4010 located on both sides of the support platform 209 and arranged opposite to each other. One end of the slide rod 409 is provided with an elastic member 407, and the other end of the slide rod 409 is connected to the second driving mechanism 4010. The opposing slide rods 409 can cooperate with the guide member 406 and move opposite to each other along the slide rails 402. The second driving mechanism 4010 is used to drive the brush body 4011 to rotate.

[0031] For example, such as Figures 1-3 As shown, the support platform 209 includes two vertically arranged support plates 201. The support plates 201 and the grinding mechanism 4 are installed on the open box body 1. The fixing member 405 is located above the support platform 209. There are two sets of grinding brush assemblies arranged opposite each other on both sides of the support platform 209. The working principle of the above-mentioned grinding machine can include:

[0032] The bar to be ground is placed on the support platform 209 and positioned below the fixing member 405. After the second drive motor is started to drive the brush body 4011 to rotate, the first drive mechanism 403 is activated. The first drive mechanism 403 drives the fixing member 405 to move downward until it contacts and presses the bar, making it fit tightly against the support platform 209, thereby fixing the bar. At the same time, as the fixing member 405 moves downward, the guide member 406 on the fixing member 405 can interact with the two sliding rods 409 that are oppositely set on the two slide rails 402 during the descent. The two sliding rods 409 are driven to move towards each other along the slide rail 402 and approach the two ends of the rod on the support platform 209. In this way, the brush bodies 4011 on both sides can make synchronous contact with the two ends of the rod. The first driving mechanism 403 supports the fixing member 405 and presses it down for a period of time. During this period, the second driving mechanism 4010 drives the brush bodies 4011 on both sides to rotate, which can simultaneously complete the deburring and grinding work at both ends of the rod. Compared with the existing technology, it is not necessary to grind one end and then flip it to the other end for grinding, which effectively improves the work efficiency.

[0033] After the grinding is completed, the first drive mechanism 403 can drive the fixed part 405 to move upward. The guide part 406 rises with the fixed part 405 and disengages from the sliding rod 409. Under the tension of the elastic part 407, the sliding rod 409 moves in the opposite direction along the slide rail 402. The two opposing sliding rods 409 move away from each other along the slide rail 402, so that the brush body 4011 leaves both ends of the bar. This facilitates the unloading of the ground bar and the loading of the next bar to be ground. Compared with two independent drive mechanisms that drive the two sets of brush bodies 4011 to move in opposite directions, the above-mentioned grinding machine uses the fixed part 405 to move in the movement of the fixed part 405. During this process, the guide part 406 drives the opposing sliding rods 409 to move synchronously in opposite directions along the slide rail 402, or the elastic part 407 drives the sliding rods 409 to automatically reset. This can reduce the number of drive mechanisms, thereby reducing the size of the grinding machine, reducing the difficulty of controlling the grinding machine, reducing operating energy consumption and equipment cost.

[0034] Furthermore, both the support platform 209 and the fixing member 405 are provided with a first slot 202, for example: Figure 1 , Figure 2 and Figure 5 As shown, the first slot 202 has a V-shaped structure, and the fixing member 405 can be a V-shaped rod. The first slots 202 on the support platform 209 and the fixing member 405 are arranged opposite each other. The bar to be ground can be placed inside the first slot 202 of the support platform 209, located directly below the fixing member 405. When the fixing member 405 moves downward, the first slot 202 squeezes the bar to make it fit tightly against the support platform 209 to fix the bar and prevent the bar from shifting during grinding. The first slot 202 further optimizes the positioning and fixing support of the bar by the support platform 209 and the fixing member 405, which can further improve the grinding efficiency and reliability.

[0035] Furthermore, the fixing member 405 is arranged perpendicular to the moving direction of the sliding rod 409, the guide member 406 is provided with a first inclined surface 4012, and the sliding rod 409 is provided with a second inclined surface 4013 that can cooperate with the first inclined surface 4012, for example: Figure 1 and Figure 2 As shown, the grinding mechanism 4 includes a U-shaped plate 401, which is upside down and fixedly connected to the top and side walls of the box 1. A vertically arranged cylinder, serving as a first driving mechanism 403, is installed inside the top of the U-shaped plate 401. A fixing member 405 is fixedly connected to the output end of the cylinder. Two vertically arranged telescopic rods 404 located on both sides of the cylinder are fixedly connected to the top of the fixing member 405. The tops of the telescopic rods 404 are fixedly connected to the top of the U-shaped plate 401, used to extend and retract with the cylinder, improving the support stability of the fixing member 405. Guide members 406 are fixedly connected to both ends of the fixing member 405. The guide members 406 have an L-shaped structure and their ends form a first inclined surface 4012 through a tapered portion. Figure 1 and Figure 3 As shown, horizontally arranged slide rails 402 are fixedly connected to both the left and right sides of the box body 1. The slide rails 402 are located outside the support platform 209. A slide rod 409 is slidably connected inside the slide rails 402. A through hole is opened on the slide rod 409. The contact area between the through hole and the slide rail 402 forms a conical cavity 408. The side of the conical cavity 408 serves as a second inclined surface 4013. Several return springs serving as elastic elements 407 are fixedly connected to one end of the slide rod 409 away from the second drive mechanism 4010. The other end of the return spring is fixedly connected to the side of the box body 1.

[0036] In its natural state, the slide rod 409 moves towards the box 1 side under the tension of the return spring until the conical cavity 408 is located below the guide member 406. When the cylinder drives the fixing member 405 to move downward, the bottom end of the guide member 406 inserts into the conical cavity 408. The first inclined surface 4012 and the second inclined surface 4013 cooperate to generate a horizontal component force, thereby squeezing the slide rod 409 and causing the slide rod 409 to move horizontally towards the support platform 209 within the slide rail 402, further stretching the return spring. When the cylinder drives the fixing member 405 to move upward, the guide member 406 disengages from the conical cavity 408, and the slide rod 409 moves in the opposite direction along the slide rail 402 to reset under the tension of the return spring. In this way, by further optimizing the movement direction layout of the fixing member 405 and the slide rod 409, and the mating surface of the guide member 406 and the slide rod 409, the coordinated movement of the slide rod 409 and the guide member 406 can be further simplified, improving operating efficiency.

[0037] Furthermore, the second drive mechanism 4010 is limited in cooperation with the slide rail 402, for example: Figure 3As shown, a grinding motor, serving as a second drive mechanism 4010, is installed at the bottom of the slide bar 409. A disc brush, serving as a brush body 4011, is installed at the output end of the grinding motor. The grinding motor can cooperate with the end of the slide rail 402 to limit the return stroke of the slide bar 409. By further limiting the movement stroke of the slide bar 409, the grinding mechanism 4 can be further simplified, the time for the brush body 4011 to advance again can be reduced, and the grinding efficiency can be further improved.

[0038] Furthermore, including a conveying mechanism 2, the support platform 209 is provided with a plurality of first slots 202, the conveying mechanism 2 being used to transfer the bar stock between adjacent first slots 202, for example: Figure 1 , Figure 4 and Figure 5 As shown, the support platform 209 includes two vertically arranged support plates 201. The two support plates 201 are fixedly connected to the bottom of the box body 1. Several evenly spaced first slots 202 are opened at corresponding positions on the top of the two support plates 201. The second slots 204 have a V-shaped structure. The rod is transferred between adjacent first slots 202 by the conveying mechanism 2, so that a single rod can be moved to the grinding mechanism 4 in sequence. There is no need for manual continuous placement or removal of the rod, which can further facilitate automated batch processing. The first slots 202 also facilitate the positioning of the rod with the fixing part 405, thereby improving the grinding efficiency.

[0039] Furthermore, the conveying mechanism 2 includes a transfer component 203 and a third driving mechanism 3. The transfer component 203 is provided with a plurality of second slots 204. The third driving mechanism 3 is used to drive the second slots 204 to rotate with the transfer component 203 between adjacent first slots 202, for example: Figure 4 and Figure 5 As shown, the transfer component 203 is located at the center between the two support plates 201, enabling the transfer component 203 to support the center position of the bar. The transfer component 203 has several second slots 204 corresponding to the first slots 202. The inner wall of the second slots 204 has an arc-shaped structure. The number of second slots 204 is equal to that of the first slots 202. The third drive mechanism 3 drives the second slots 204 to rotate with the transfer component 203 between adjacent first slots 202. The second slots 204 can support the bar and cooperate with the bar to limit the bar's deviation, ensuring that the bar remains stable during the transfer process. The support bar moves progressively between two adjacent first slots 202, further adapting to the intermittent operation of grinding and avoiding the frequent start and stop of the conveying mechanism 2, which increases the operating energy consumption and failure risk.

[0040] Furthermore, the third drive mechanism 3 includes a rotating main shaft 302, a driven shaft 303, two eccentric wheels 208, and two connecting members 207. The two eccentric wheels 208 are eccentrically connected to the main shaft 302 and the driven shaft 303, respectively. A connecting rod 205 is movably connected between the two eccentric wheels 208. One end of the connecting member 207 is eccentrically connected to the eccentric wheel 208, and the other end of the connecting member 207 is connected to the transfer member 203. For example: Figures 4-6 As shown, a drive motor 301 is mounted on the outer side of the housing 1. The output end of the drive motor 301 passes through the side of the housing 1 and is fixedly connected to one end of the main shaft 302. The other end of the main shaft 302 rotatably passes through an adjacent support plate 201 and is fixedly connected to an eccentric wheel 208. The support plate 201 can support the rotation of the main shaft 302 to improve stability. The fixed connection position between the main shaft 302 and the eccentric wheel 208 is offset from the center position of the eccentric wheel 208. One end of the driven shaft 303 is rotatably connected to the inner side of the housing 1, or directly rotatably connected to the support plate 201. The other end of the driven shaft 303 passes through the adjacent support plate 201. It has a Z-shaped structure, and one end is fixedly connected to another eccentric wheel 208. The driven shaft 303 can be supported to rotate by the support plate 201, and at the same time, it can also support the transfer component 203 to complete the transfer action, improving stability. The fixed connection position between the driven shaft 303 and the eccentric wheel 208 is offset from the center position of the eccentric wheel 208. The bottom of both ends of the transfer component 203 are fixedly connected to the protruding plate 206. One side of the protruding plate 206 is fixedly connected to a Z-shaped rocker arm as a connecting component 207. The other end of the Z-shaped rocker arm is movably connected to the eccentric wheel 208. The two eccentric wheels 208 located at the bottom of the transfer component 203 are movably connected to the two ends of the connecting rod 205 respectively.

[0041] The working principle of the third drive mechanism 3 mentioned above can include:

[0042] When a single rod is placed in the first slot 202 on one side of the opening of the box 1, i.e., in the outermost first slot 202, the drive motor 301 is started to drive the main shaft 302 to rotate. The main shaft 302 provides power, which drives the eccentric wheel 208 connected to it to perform eccentric circular motion around the axis of the main shaft 302. Through the transmission action of the connecting rod 205, the other eccentric wheel 208 also produces the same motion trajectory and performs eccentric circular motion around the axis of the driven shaft 303. The eccentric motion of the two eccentric wheels 208 is transmitted through two connecting parts 207, i.e., Z-shaped rocker arms, which drive the transfer component 203 to reciprocate, so that the second slot 204 moves with the transfer component 203. The rotational movement between adjacent first slots 202 is as follows: First, the second slot 204 is located below the previous first slot 202. When the second slot 204 moves obliquely upward with the transfer member 203, it will lift the bar in the previous first slot 202. Then, the second slot 204 moves obliquely downward with the movement trajectory of the transfer member 203, so that the second slot 204 will move the lifted bar to the position of the next first slot 202. As the second slot 204 continues to move downward, it can detach from the lowered bar. In this way, the bar is transferred and moved between adjacent first slots 202. Then, the second slot 204 moves and resets with the transfer member 203.

[0043] Since there are multiple first slots 202 and second slots 204, multiple bars can be moved sequentially and moved one position backward through corresponding transfer. This process also allows a single bar to be ground to be moved sequentially to the fixing part 405 of the grinding mechanism 4, and to complete the grinding work in conjunction with the grinding components. The whole process does not require manual continuous placement or removal of bars. By further optimizing the third drive mechanism 3, the transportation mechanism can be further simplified and the convenience of operation can be improved.

[0044] Furthermore, a control system is included, connected to the first drive mechanism 403, the second drive mechanism 4010, and the third drive mechanism 3. For example, the control system is electrically connected to the air source control of the cylinder, the grinding motor, and the drive motor 301. The drive motor 301 is a geared motor, so that the transfer process is relatively slow, allowing working time for the grinding mechanism 4. After each grinding mechanism 4 is completed, the ground bar can be moved out of the first slot 202 at that position, and the next bar is placed in the first slot 202 below the fixing member 405 for grinding. The control system coordinates the operation of the drive motor 301 and the cylinder, controls the extension and retraction of the cylinder and the duration of the cylinder extension, and ensures that the bar fixed in the first slot 202 completes the normal grinding process.

[0045] Furthermore, it includes a feeding trough 504 located at one end of the conveying mechanism 2 and arranged at an angle, for example: Figure 4 and Figure 5As shown, the top and one side of the box body 1 are open. A feeding structure 5 is installed on the side of the support plate 201 of the box body 1. The feeding structure 5 includes two spaced feeding rods 501, both of which are inclined. The bottom of the feeding rods 501 is fixedly connected to the top of the outer side of the support plate 201, and the bottom of the feeding rods 501 is fixedly connected to the bottom of the box body 1 through a fixing plate 503. An L-shaped limiting plate 502 is fixedly connected to the side of the feeding rods 501, so that the two L-shaped limiting plates 502 and the feeding rods 501 form a conveying mechanism. The inclined feeding trough 504 allows the bars to be ground to be placed into it sequentially. The bottom bar will fall into the outermost first slot 202. When the bar in this first slot 202 is transferred to the next first slot 202, the other bars will fall into the outermost first slot 202 by their own weight. Therefore, multiple bars can be placed in the feeding structure 5 at one time without the need for manual feeding. This further facilitates automatic feeding and transfer, making the operation more convenient and improving the processing efficiency.

[0046] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. All equivalent embodiments or modifications made without departing from the spirit of the present utility model should be included within the scope of protection of the present utility model.
