Description

Technical Field

[0001] This invention relates to the technical field of aluminum tube processing, and more particularly to an aluminum tube end face grinding device. Background Technology

[0002] Aluminum tubes are widely used structural materials in the industrial field, and the quality of their end-face grinding directly affects the accuracy of subsequent welding or assembly. Traditional grinding equipment typically uses clamps to hold the tubes from the outside, and the opening and closing of the clamps are controlled by a drive mechanism above the table. However, this design results in the drive components occupying a large amount of operating space, which not only increases the size of the equipment, but also hinders the operator's observation and adjustment of the clamping status, which is particularly inconvenient in small-scale operation scenarios.

[0003] In existing equipment, the drive mechanisms of the clamps, such as cylinders or motors, are often directly mounted above the machine table, increasing the equipment height and making the layout cramped. Although some solutions attempt to simplify the drive structure, the lateral extension of the transmission components still interferes with the aluminum tube feeding path and the movement range of the grinding mechanism. Therefore, there is an urgent need for a drive layout solution that can free up table space and improve the compactness of the equipment.

[0004] On the other hand, conventional clamping units often employ segmented jaws or discontinuous contact surfaces, which can easily lead to localized stress concentrations on the aluminum tube surface, resulting in clamping indentations or scratches. This damage is particularly problematic for thin-walled aluminum tubes requiring high surface finish, potentially causing stress cracking during subsequent use. Current technology has not effectively integrated the concealment of the drive mechanism with the protection of the clamping surface, thus hindering further improvements in grinding quality. Summary of the Invention

[0006] (II) Technical Solution To achieve the above objectives, the present invention provides an aluminum tube end face grinding device, including a frame, a grinding mechanism and a clamping mechanism. The clamping mechanism includes a clamping assembly located at the top of the frame and a clamping drive mechanism located at the bottom of the frame. The clamping drive mechanism is connected to the clamping assembly for driving the clamping assembly to open and close to clamp the aluminum tube. The grinding mechanism is located at one end of the frame and is connected to the frame via a sliding mechanism, allowing it to approach or move away from the end face of the aluminum tube to be ground, which is fixed by the clamping assembly.

[0007] A further technical solution is that the clamping assembly includes an arc-shaped plate, a guide seat, and a guide rod; The paired arc-shaped plates form a clamping space for holding the aluminum tube; Each of the arc-shaped plates has a plurality of guide rods fixedly connected at intervals on one side. Corresponding to each guide rod, a guide seat is fixedly provided on the frame. The guide rod and the guide seat are slidably engaged to push the arc-shaped plate to reciprocate along the axial direction of the guide rod.

[0008] A further technical solution is that the cross-sectional shape of the arc plate is semi-circular and matches the outer surface of the aluminum tube to be clamped, and each of the guide rods is simultaneously slidably connected to two guide seats.

[0009] A further technical solution is that the clamping drive mechanism includes a drive motor and a linkage sliding mechanism; The drive motor is fixed to the bottom surface of the frame and is connected to the end of the guide rod away from the arc plate through the linkage sliding mechanism, so as to drive the guide rod to move axially.

[0010] A further technical solution is that the linkage sliding mechanism includes a side plate, an L-shaped connecting plate, a guide rail, a slider, and a linkage; The side plates are disposed on both sides of the frame and are fixedly connected to the guide rod; The guide rail is fixed to the bottom surface of the frame and is slidably connected to the slider. The slider is connected to the side plate through the L-shaped connecting plate. The two ends of the connecting rod are respectively hinged to the output end of the drive motor and the L-shaped connecting plate; The drive motor can drive the slider and side plate, which are fixedly connected to the L-shaped connecting plate, to move along the guide rail via the connecting rod.

[0011] A further technical solution is that the grinding mechanism includes a grinding machine assembly slidably disposed at the end of the frame and an adjustment mechanism; The grinding machine assembly includes a mounting base, a grinding motor fixed on the mounting base, and a grinding disc connected to the output end of the grinding motor; An opening is provided at the end of the frame, and a guide shaft is provided inside the opening. The mounting base is provided with a guide hole corresponding to the guide shaft, and the guide hole is slidably connected to the guide shaft. The adjustment mechanism includes a handrail assembly, a stop plate, and a spring; The blocking plate is fixed to the opening to seal the opening. The handrail assembly is slidably disposed on the blocking plate. One end of the handrail assembly abuts against the mounting base. The spring is sleeved on the guide shaft on the side of the mounting base away from the handrail assembly. The position of the grinding assembly on the guide shaft can be changed by changing the position of the handrail assembly.

[0012] A further technical solution is that the handrail assembly includes a handle, a baffle, and a connecting shaft; The handle and the baffle are connected by multiple connecting shafts. The baffle is provided with sliding holes corresponding to the multiple connecting shafts. The connecting shafts are slidably connected to the sliding holes.

Detailed Implementation

[0018] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] This embodiment provides an aluminum tube end face grinding device, such as... Figures 1 to 4 As shown, it includes a frame 1, a grinding mechanism 2, and a clamping mechanism 3.

[0020] The clamping mechanism 3 includes a clamping assembly 31 located at the top of the frame 1 and a clamping drive mechanism 32 located at the bottom of the frame 1. The clamping drive mechanism 32 is connected to the clamping assembly 31 for driving the clamping assembly 31 to open and close to clamp the aluminum tube.

[0021] The grinding mechanism 2 is located at one end of the frame 1 and is connected to the frame 1 through a sliding mechanism, and can approach or move away from the end face of the aluminum tube to be ground, which is fixed by the clamping assembly 31.

[0022] Specifically, the aluminum tube end face grinding equipment disclosed in this embodiment is mounted on a frame 1, which is a table structure providing a stable mounting support for all components of the equipment. The equipment includes a grinding mechanism 2 and a clamping mechanism 3. The clamping mechanism 3 consists of a clamping assembly 31 and a clamping drive mechanism 32. The clamping assembly 31 is positioned above the table of the frame 1, while the clamping drive mechanism 32 is correspondingly installed below the table of the frame 1. These two components form a vertical transmission and cooperation structure. The clamping drive mechanism 32 outputs power to drive the clamping assembly 31 to complete the opening and closing action, thereby achieving stable clamping and releasing of the aluminum tube. Simultaneously, the clamping center of the clamping assembly 31 coincides with the center of the table of the frame 1, ensuring the center positioning accuracy of the aluminum tube after clamping. The grinding mechanism 2 is mounted on one end of the frame 1. The grinding mechanism 2 is connected to the frame 1 through a sliding mechanism. With the help of the transmission action of the sliding mechanism, the grinding mechanism 2 can make a linear sliding motion in the direction of approaching or moving away from the aluminum tube. Thus, the distance between the grinding mechanism 2 and the end face of the aluminum tube to be ground can be flexibly adjusted according to the actual position of the aluminum tube and the processing requirements of the end face to be ground.

[0023] The machining center of the grinding mechanism 2 is aligned with the clamping center line of the clamping assembly 31 to ensure that the grinding operation of the grinding mechanism 2 can be accurately applied to the end face of the aluminum tube to be ground. To further improve the support stability of the aluminum tube during the grinding process and prevent the aluminum tube from shifting or shaking due to the grinding force, a limiting block 4 is preferably provided on the opposite side of the frame 1 to the grinding mechanism 2. The limiting block 4 cooperates with the clamping assembly 31 to form effective support from the other end of the aluminum tube, so that the aluminum tube always maintains a stable positioning state during the grinding operation.

[0024] The above technical solution sets the clamping mechanism 3 as a clamping component 31 and a clamping drive mechanism 32 that are separated into upper and lower parts, and installs them separately in combination with the table structure of the frame 1. This makes reasonable use of the space layout of the frame 1 and solves the problem of space occupation above the table of the clamping drive structure.

[0025] The grinding mechanism 2 is connected to the frame 1 through a sliding mechanism, which makes it adjustable in position, adapting to the end face grinding needs of aluminum tubes of different specifications, and improving the versatility and adaptability of the equipment.

[0026] The addition of the vertical limiting block 4 to the grinding mechanism 2 forms a bidirectional support and limiting with the clamping component 31, which effectively suppresses the deviation and shaking caused by force during the grinding of aluminum tubes, further ensuring the stability of the grinding operation. At the same time, it can make the transmission of grinding force more uniform and improve the grinding quality of the aluminum tube end face.

[0027] In this embodiment, the clamping assembly 31 includes an arc-shaped plate 311, a guide seat 312, and a guide rod 313. Pairs of arc-shaped plates 311 form a clamping space for clamping aluminum tubes. Multiple guide rods 313 are fixedly connected at intervals to one side of each arc-shaped plate 311. Corresponding to each guide rod 313, a guide seat 312 is fixedly mounted on the frame 1. The guide rod 313 slides in conjunction with the guide seat 312, pushing the arc-shaped plate 311 to reciprocate along the axial direction of the guide rod 313.

[0028] The arc plate 311 has a semi-circular cross-sectional shape and matches the outer surface of the aluminum tube to be clamped. Each guide rod 313 is simultaneously slidably connected to two guide seats 312.

[0029] Preferably, the guide rod 313 and the arc plate 311 can be connected in a detachable manner. Specifically, one end of the guide rod 313 is provided with an external thread, a connecting block is added to the outer side of the arc plate 311, and an internal thread hole matching the external thread is opened on the connecting block. The guide rod 313 and the arc plate 311 are connected by this detachable connection method of thread.

[0030] Specifically, the arc-shaped plates 311 are arranged in pairs, with two arc-shaped plates 311 cooperating to form a clamping space that matches the outer contour of the aluminum tube, thereby achieving a wrap-around clamping of the aluminum tube. Each arc-shaped plate 311 has multiple guide rods 313 fixedly connected at intervals on the side away from the clamping space. A guide seat 312 is fixedly installed on the frame 1 at the position corresponding to each guide rod 313. The guide rod 313 passes through the corresponding guide seat 312 and forms a sliding engagement with the guide seat 312. Under the power drive of the clamping drive mechanism 32, the guide rod 313 can reciprocate within the guide seat 312 along its own axis, thereby pushing the arc-shaped plates 311 to move synchronously, realizing the opening and closing of the clamping space to complete the clamping and releasing of the aluminum tube.

[0031] In a preferred embodiment, the cross-sectional shape of the arc plate 311 is set to semi-circular, and its arc-shaped inner side is in contact with the outer surface of the aluminum tube to be clamped, which can improve the contact fit with the aluminum tube and enhance the clamping stability. In addition, each guide rod 313 is simultaneously inserted into two guide seats 312 and slidably connected to them, further improving the guiding accuracy and support stability of the guide rod 313 during the sliding process.

[0032] Preferably, the guide rod 313 and the arc-shaped plate 311 are assembled in a detachable connection manner. An external thread is provided at the end of the guide rod 313 facing the arc-shaped plate 311. A connecting block is fixedly connected to the outer surface of the arc-shaped plate 311. The connecting block has an internal threaded hole that matches the external thread of the guide rod 313. The guide rod 313 is screwed into the internal threaded hole of the connecting block through its external thread, achieving a detachable and fixed connection with the arc-shaped plate 311. The guide rod 313 or the arc-shaped plate 311 can be disassembled and replaced according to actual clamping requirements.

[0033] The aforementioned further technical solution utilizes paired arc-shaped plates 311 to form a clamping space. Combined with the semi-circular cross-section of the arc-shaped plates 311 and their fit with the outer surface of the aluminum tube, this increases the contact area with the aluminum tube, enhancing the clamping's firmness and stability, and preventing displacement of the aluminum tube after clamping. The guide rods 313 slide against the corresponding guide seats 312 on the frame 1, and the structural design of a single guide rod 313 cooperating with two guide seats 312 provides precise and stable guidance for the movement of the arc-shaped plates 311, ensuring the straightness of the arc-shaped plates 311's opening and closing movement, thereby guaranteeing the center positioning accuracy of the aluminum tube clamping. The guide rods 313 are spaced apart on one side of the arc-shaped plates 311, ensuring uniform force distribution on the arc-shaped plates 311 and preventing jamming or tilting during movement.

[0034] The guide rod 313 and the arc plate 311 are connected by a threaded detachable connection, which not only makes disassembly and assembly easy, but also allows for flexible replacement of the arc plate 311 or guide rod 313 according to the specifications of the aluminum tube to be clamped and the usage requirements of the equipment. This improves the versatility and maintenance convenience of the clamping assembly 31, and also allows for individual replacement when parts are worn or damaged, reducing the maintenance cost of the equipment.

[0035] In this embodiment, the clamping drive mechanism 32 includes a drive motor 321 and a sliding mechanism of connecting rod 326. The drive motor 321 is fixed to the bottom surface of the frame 1 and is connected to the end of the guide rod 313 away from the arc plate 311 through the sliding mechanism of connecting rod 326, so as to drive the guide rod 313 to move axially.

[0036] Specifically, the sliding mechanism of the connecting rod 326 includes a side plate 322, an L-shaped connecting plate 323, a guide rail 324, a slider 325, and a connecting rod 326. The side plate 322 is disposed on both sides of the frame 1 and is fixedly connected to the guide rod 313. The guide rail 324 is fixed to the bottom surface of the frame 1 and is slidably connected to the slider 325. The slider 325 is connected to the side plate 322 through the L-shaped connecting plate 323. The two ends of the connecting rod 326 are respectively hinged to the output end of the drive motor 321 and the L-shaped connecting plate 323. The drive motor 321 can drive the slider 325 and the side plate 322, which are fixedly connected to the L-shaped connecting plate 323, to move along the guide rail 324 through the connecting rod 326.

[0037] Specifically, the clamping drive mechanism 32 consists of a drive motor 321 and a sliding mechanism of a connecting rod 326. The drive motor 321 is fixedly installed on the bottom surface of the frame 1 platform to provide power output for the opening and closing of the clamping assembly 31. The drive motor 321 is connected to the end of the guide rod 313 away from the arc plate 311 through the sliding mechanism of the connecting rod 326. The power of the drive motor 321 is transmitted to the guide rod 313 through the sliding mechanism of the connecting rod 326, thereby driving the guide rod 313 to reciprocate along its own axis, and thus driving the arc plate 311 to complete the opening and closing action.

[0038] In the sliding mechanism of link 326, side plates 322 are correspondingly arranged on both sides of the frame 1, and the side plates 322 are fixed to the guide rod 313 to achieve synchronous movement of the two; the guide rail 324 is fixedly arranged on the bottom surface of the platform of the frame 1, and the slider 325 is adapted to the guide rail 324 to form a sliding fit. The slider 325 is also fixedly connected to the side plate 322 through the L-shaped connecting plate 323, so that the side plate 322, the L-shaped connecting plate 323 and the slider 325 form a linkage structure; link 32 The two ends of 6 are respectively hinged to the output end of the drive motor 321 and the L-shaped connecting plate 323. When the drive motor 321 starts, the power at its output end drives the connecting rod 326 to swing. During the swing, the connecting rod 326 pushes the L-shaped connecting plate 323 that is hinged to it, thereby driving the slider 325 to slide linearly along the guide rail 324. The sliding of the slider 325 simultaneously drives the side plate 322 and the guide rod 313 to move axially, ultimately realizing the opening and closing action of the clamping assembly 31.

[0039] The aforementioned further technical solution converts the power of the drive motor 321 into the linear reciprocating motion of the guide rod 313 through the swing motion of the connecting rod 326. The transmission structure is simple and the power transmission is efficient and stable, providing stable power support for the opening and closing of the clamping assembly 31 and ensuring the smoothness of the clamping action. The sliding mechanism of the connecting rod 326 provides precise guidance for the movement of the side plate 322 and the guide rod 313 through the sliding cooperation of the guide rail 324 and the slider 325. With the corresponding arrangement of the side plate 322 and the two sides of the frame 1, the guide rods 313 on both sides can move synchronously and smoothly, ensuring that the opening and closing actions of the paired arc plates 311 are synchronized and consistent, ensuring the centering and stability of the aluminum tube clamping. Except for the side plate 322, all components of the entire clamping drive mechanism 32 are arranged on the bottom surface of the frame 1, effectively avoiding interference with the upper clamping assembly 31 and grinding mechanism 2.

[0040] In this embodiment, the grinding mechanism 2 includes a grinding machine assembly 21 slidably disposed at the end of the frame 1 and an adjustment mechanism 22. The grinding machine assembly 21 includes a mounting base 211, a grinding motor 212 fixed on the mounting base 211, and a grinding disc 213 connected to the output end of the grinding motor 212. An opening 11 is formed at the end of the frame 1, and a guide shaft 12 is provided inside the opening 11. The mounting base 211 is provided with a guide hole corresponding to the guide shaft 12, and the guide hole is slidably connected to the guide shaft 12.

[0041] The adjustment mechanism 22 includes a handrail assembly 221, a blocking plate 222, and a spring 223. The blocking plate 222 is fixed at the opening 11 to block the opening 11. The handrail assembly 221 is slidably mounted on the blocking plate 222. One end of the handrail assembly 221 abuts against the mounting base 211. The spring 223 is sleeved on the guide shaft 12 on the side of the mounting base 211 away from the handrail assembly 221. By changing the position of the handrail assembly 221, the position of the grinding component on the guide shaft 12 can be changed.

[0042] The handrail assembly 221 includes a handle 2211, a baffle 2212, and a connecting shaft 2213. The handle 2211 and the baffle 2212 are connected by multiple connecting shafts 2213. The baffle 222 is provided with sliding holes corresponding to the multiple connecting shafts 2213. The connecting shafts 2213 are slidably connected to the sliding holes. The baffle 2212 abuts against the mounting base 211.

[0043] Specifically, the grinding mechanism 2 consists of a grinding machine assembly 21 slidably mounted on the end of the frame 1 and an adjustment mechanism 22 for adjusting the position of the grinding machine assembly 21. The grinding machine assembly 21 includes a mounting base 211, a grinding motor 212, and a grinding disc 213. The grinding motor 212 is fixedly mounted on the mounting base 211, and the grinding disc 213 is connected to the output end of the grinding motor 212. The grinding motor 212 drives the grinding disc 213 to rotate, thereby achieving the grinding operation on the end face of the aluminum tube. An opening 11 is provided at the end of the table surface of the frame 1. A guide shaft 12 is fixedly mounted inside the opening 11. A guide hole is provided on the mounting base 211 at the position corresponding to the guide shaft 12. The guide hole is fitted onto the guide shaft 12 and forms a sliding fit with the guide shaft 12, allowing the grinding machine assembly 21 to slide linearly within the opening 11 at the end of the frame 1 along the axial direction of the guide shaft 12.

[0044] The adjustment mechanism 22 includes a handrail assembly 221, a blocking plate 222, and a spring 223. The blocking plate 222 is fixedly installed at the opening 11 at the end of the frame 1 to block the opening 11. The handrail assembly 221 slides through the blocking plate 222, and one end of the handrail assembly 221 abuts against the mounting seat 211. On the side of the mounting seat 211 away from the handrail assembly 221, a spring 223 is also sleeved on the guide shaft 12. The elastic force of the spring 223 can push against the mounting seat 211. By applying force to change the sliding position of the handrail assembly 221 on the blocking plate 222, the operator can drive the mounting seat 211 to slide along the guide shaft 12, thereby changing the overall position of the grinding machine assembly 21 on the guide shaft 12 to adapt to the grinding operation requirements of the aluminum tube end face.

[0045] The handrail assembly 221 is specifically composed of a handle 2211, a baffle 2212 and a connecting shaft 2213. The handle 2211 and the baffle 2212 are arranged opposite to each other and are fixedly connected by multiple connecting shafts 2213. The baffle 222 has a sliding hole corresponding to the position of each connecting shaft 2213. The connecting shaft 2213 passes through the corresponding sliding hole and forms a sliding fit with the sliding hole, so that the entire handrail assembly 221 can slide smoothly along the axial direction of the connecting shaft 2213.

[0046] The grinding machine assembly 21 slides with the guide shaft 12 in the opening 11 of the frame 1 through the guide hole of the mounting base 211, providing precise guidance for the sliding of the grinding machine assembly 21, ensuring that the grinding disc 213 always moves along the center line of the aluminum tube clamping, ensuring the centering of the grinding operation, and improving the grinding accuracy of the aluminum tube end face.

[0047] The adjustment mechanism 22, through the coordinated design of the handrail assembly 221, spring 223 and mounting base 211, allows the operator to flexibly adjust the position of the grinding machine assembly 21 by manipulating the handrail assembly 221. With the elastic pushing action of the spring 223, a flexible grinding contact is formed between the grinding disc 213 and the end face of the aluminum tube, avoiding over-grinding or damage to the end face of the aluminum tube caused by hard contact, thus improving the grinding quality.

[0048] Preferably, a protective pad is provided on the inner clamping surface of the arc-shaped plate 311. When the clamping assembly 31 clamps the aluminum tube, the flexible properties of the protective pad form a buffer, preventing the hard clamping surface of the arc-shaped plate 311 from directly contacting the outer surface of the aluminum tube and causing scratches, indentations, or other damage to the aluminum tube surface. At the same time, the protective pad can increase the contact friction with the outer surface of the aluminum tube, improve the clamping tightness, reduce slippage and shaking of the aluminum tube during the grinding operation, and further ensure clamping stability and grinding accuracy.

If the specific posture changes, the directional indicator will also change accordingly.
