Abstract
Description
Technical Field
[0001] This utility model belongs to the field of industrial grinding technology, specifically relating to a crossbar grinding device with a dust removal structure. Background Technology
[0002] Crossbars, as important components commonly used in metal structure connections, mechanical supports, or industrial frame construction, often have defects such as surface burrs, weld flash, or oxide layers after forming. Therefore, they need to be ground before being put into use. Traditional crossbar grinding methods mostly rely on manual or semi-automatic equipment, which are inefficient and inconsistent, making it difficult to meet the needs of modern mass production and precision processing.
[0003] While existing automated grinding equipment can drive a crossbar to rotate and perform grinding operations using a fixed grinding head, it still has shortcomings in the following aspects:
[0004] First, existing grinding devices are poorly adaptable to crossbars of different sizes and lengths, requiring frequent changes to the clamping mechanism or grinding head position, resulting in cumbersome adjustments and reduced work efficiency. Second, some devices have non-adjustable grinding positions or poor adjustment precision during the grinding process, making it difficult to achieve fine grinding in specific areas or angles. In addition, crossbars generate a large amount of metal dust during grinding, which, without an efficient dust removal structure, not only pollutes the working environment but also affects the health of operators and may even cause equipment wear.
[0005] In particular, in most current equipment, the dust removal device cannot move synchronously with the grinding head, resulting in misalignment between the air intake and the grinding position. This causes dust to not be effectively captured in a timely manner, seriously affecting the dust removal effect and thus reducing the cleanliness of the overall processing environment and the service life of the equipment. Utility Model Content
[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a crossbar grinding device with a dust removal structure. It can achieve a crossbar grinding device with a reasonable structure, flexible grinding position, adaptability to crossbars of different sizes, and a high-efficiency synchronous dust removal structure, so as to improve grinding efficiency and dust removal effect and meet the needs of precision production.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a crossbar grinding and device with a dust removal structure, including a base frame, a rotary drive motor is provided on one side of the base frame and a support platform is provided on the other side, and a first track rod is arranged laterally on the front side and a second track rod is arranged laterally on the rear side inside the base frame;
[0008] A thrusting and pressing mechanism is installed on the top of the support platform. The thrusting and pressing mechanism is used to press one end of the crossbar. A grinding mechanism is slidably installed on the surface of the first track bar.
[0009] A second slide plate is slidably mounted on the surface of the second track rod. A connecting plate is connected between the grinding mechanism and the bottom of the second slide plate. A suction box is provided on the top of the second slide plate. A hose is connected to the rear side of the suction box. The end of the hose is connected to a vacuum cleaner.
[0010] Furthermore, at least two supporting V-shaped blocks are fixed inside the upper part of the base frame to support the crossbars. The supporting V-shaped blocks are placed between the rotary drive motor and the thrust extrusion mechanism. A vertical plate is provided on the top of the support platform. The thrust extrusion mechanism includes a bearing seat fixed on the top of the support platform. Fixed rods are symmetrically arranged between the bearing seat and the vertical plate.
[0011] Furthermore, a rotating shaft is slidably mounted at the center of the bearing housing surface, and a pressing plate is fixed at one end of the rotating shaft. The pressing plate presses one end of the cross rod so that the other end of the cross rod contacts the output shaft of the rotary drive motor.
[0012] Furthermore, sliders are slidably mounted on the surfaces of the two fixed rods, and the end of the rotating shaft opposite to the extrusion plate is rotatably mounted on the slider. A spring is sleeved on the surface of the fixed rod, and the spring applies a thrust to the slider in the direction of the bearing seat.
[0013] Furthermore, the grinding mechanism includes a first slide plate that slides on the surface of the first track rod, a mounting plate that is vertically fixed on the upper surface of the first slide plate, and a swing plate that is rotatably mounted on one side of the mounting plate.
[0014] Furthermore, a sandpaper belt is provided on one side of the swing plate, the sandpaper belt is driven by a motor, and one end of the swing plate is uniformly provided with protruding teeth with its rotation axis as the center.
[0015] Furthermore, a threaded rod is horizontally rotatably mounted on one side of the mounting plate, and a toothed rod is screwed onto the surface of the threaded rod, with the toothed rod meshing with the protruding teeth.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] This invention, by setting up a rotary drive motor and a thrust pressing mechanism to clamp the crossbar, enables the crossbar to rotate stably during the grinding process. This effectively solves the problem of poor grinding accuracy caused by insecure clamping and rotational deviation of the crossbar during grinding in the prior art, and improves the stability and consistency of grinding.
[0018] In this invention, the grinding mechanism is installed on the first track rod, and the angle of the swing plate is controlled by the meshing of the threaded rod and the toothed rod, thereby adjusting the contact angle between the sandpaper belt and the cross rod. It can flexibly grind according to cross rods of different sizes and angles, effectively solving the problems of the traditional grinding device having an unadjustable grinding position and being unable to adapt to cross rods of different configurations, thus improving the versatility and adaptability of the equipment.
[0019] This invention solves the problem of misalignment between the dust collection device and the grinding position in existing grinding equipment by setting the suction box on the second slide plate and linking it with the grinding mechanism through the connecting plate. This allows the suction box to move synchronously with the grinding mechanism, ensuring that the dust collection port is always aligned with the grinding area. It improves dust collection efficiency, improves the working environment, and extends the service life of the equipment.
[0020] This invention enables the extrusion plate to have an automatic reset function by setting a slider and spring structure on the fixed rod. When installing the cross rod, simply move the slider to release the space. After the cross rod is placed in place, the spring automatically resets to return the extrusion plate to the clamped state. This effectively improves the convenience and efficiency of cross rod clamping, reduces the intensity of manual intervention, and is suitable for production scenarios with frequent part changes.

[0028] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0029] refer to Figures 1-6 As shown, a crossbar grinding and device with a dust removal structure includes a base frame 1. A rotary drive motor 13 is installed on the upper side of one side of the base frame 1. The output shaft of the rotary drive motor 13 is horizontally arranged to drive the crossbar to rotate and achieve full-angle grinding. A support platform 14 is installed on the other side of the base frame 1. The support platform 14 is used to support the thrust extrusion mechanism 2 and stabilize the overall structure of the device. A first track rod 11 is horizontally arranged on the front side inside the base frame 1, providing a longitudinal movement track for the grinding mechanism 3. A second track rod 12 is horizontally arranged on the rear side of the base frame 1, providing synchronous guidance support for the second slide plate 4. The first track rod 11 and the second track rod 12 provide linkage paths for the grinding and dust removal structures, respectively, to achieve synchronous correspondence between the dust removal position and the grinding position. A support platform 14 is installed on the top. The thrusting and pressing mechanism 2 applies a preload to one end of the crossbar, pressing the other end against the output shaft of the rotary drive motor 13 to achieve stable rotation. A grinding mechanism 3 is slidably mounted on the surface of the first track rod 11. The grinding mechanism 3 can precisely position the grinding area along the track to adapt to the grinding needs of crossbars of different lengths. A second slide plate 4 is slidably mounted on the surface of the second track rod 12. The second slide plate 4 and the grinding mechanism 3 are fixedly connected by a connecting plate 5 to ensure that the two remain synchronized when moving laterally. A suction box 41 is provided on the top of the second slide plate 4. The suction box 41 has an intake port that is aligned with the grinding area to remove grinding dust in real time. A hose 42 is connected to the rear of the suction box 41. The hose 42 flexibly connects to a vacuum cleaner to achieve efficient dust removal and improve the cleanliness of the working environment.
[0030] refer to Figure 2 and Figure 3As shown, at least two support V-blocks 15 are fixed inside the upper part of the base frame 1 to support the crossbar. The support V-blocks 15 are rigid structures with an anti-slip covering layer on the surface to prevent the crossbar from slipping and ensure that the crossbar remains stable during rotation and grinding. The support V-blocks 15 are placed between the rotary drive motor 13 and the thrust extrusion mechanism 2 to ensure effective transmission of rotational power and accurate positioning of the grinding area. A vertical plate 141 is provided on the top of the support platform 14. The vertical plate 141 serves as a fixed support structure for installing the components of the thrust extrusion mechanism 2 and providing vertical support force. The thrust extrusion mechanism 2 includes a bearing seat 21 fixed on the top of the support platform 14. The bearing seat 21 is a metal casting structure with guide holes inside for installing and guiding the movement of the rotating shaft 23. Fixed rods 142 are symmetrically arranged between the bearing seat 21 and the vertical plate 141. The two fixed rods 142 are arranged in parallel and serve as guide rails for the slider 22 to improve the stability and operation accuracy of the extrusion mechanism.
[0031] refer to Figures 1-3 As shown, a rotating shaft 23 is slidably mounted on the center of the bearing housing 21. The rotating shaft 23 is a cylindrical metal part used to transmit axial compressive force to one end of the cross rod for positioning. A pressing plate 24 is fixed to one end of the rotating shaft 23. The pressing plate 24 is made of steel plate with a slightly curved surface to fit the outer wall structure of the cross rod. The pressing plate 24 presses one end of the cross rod so that the other end of the cross rod contacts the output shaft of the rotary drive motor 13, ensuring that no displacement or slippage occurs during the rotation process, thereby improving rotational stability and grinding accuracy.
[0032] refer to Figure 3 As shown, sliders 22 are slidably mounted on the surfaces of the two fixed rods 142. Guide sleeves are nested inside the sliders 22 to reduce friction and improve sliding smoothness. The end of the rotating shaft 23 facing away from the extrusion plate 24 is rotatably mounted on the slider 22. The movement of the slider 22 drives the rotating shaft 23 to move forward and backward in the axial direction to complete the extrusion action. A spring 25 is sleeved on the surface of the fixed rods 142. The spring 25 is a helical compression spring. One end of the spring 25 contacts the vertical plate 141, and the other end abuts against the slider 22. The spring 25 applies a pushing force to the slider 22 in the direction of the bearing seat 21, so that the rotating shaft 23 and the extrusion plate 24 can automatically reset during the assembly process, which facilitates quick positioning of the cross rods and improves operating efficiency.
[0033] refer to Figure 4 and Figure 6 As shown, the grinding mechanism 3 includes a first sliding plate 31 that slides on the surface of the first track rod 11. The first sliding plate 31 is provided with a guide groove to adapt to the cross-sectional shape of the track rod, ensuring smooth sliding without jamming. A mounting plate 32 is vertically fixed on the upper surface of the first sliding plate 31. The mounting plate 32 is made of metal sheet and serves as the mounting base for each grinding component. A swing plate 33 is rotatably mounted on one side of the mounting plate 32. The angle of the swing plate 33 can be adjusted by a rotation shaft, so that the sandpaper belt 36 can be fitted to different areas of the cross rod for grinding.
[0034] refer to Figures 4-6 As shown, a sandpaper belt 36 is provided on one side of the swing plate 33. The sandpaper belt 36 is installed around the roller structure. The roller is driven by a motor to form a cyclic grinding path to adapt to cross bars of different lengths and surface curvatures. The sandpaper belt 36 is driven by a motor to form relative motion on the outer surface of the rotating cross bars to achieve efficient grinding. One end of the swing plate 33 is uniformly provided with protruding teeth 331 with its rotation axis as the center. The protruding teeth 331 are tooth-shaped structures that mesh with the toothed bar 35 to control the swing angle and ensure that the sandpaper belt 36 contacts the workpiece surface at the optimal angle.
[0035] refer to Figures 4-6 As shown, a threaded rod 34 is horizontally rotatably mounted on one side of the mounting plate 32. The threaded rod 34 is rotated by an external adjustment knob, and the structure is equipped with a bearing support to reduce rotational resistance. A toothed rod 35 is screwed onto the surface of the threaded rod 34. The threaded engagement between the toothed rod 35 and the threaded rod 34 enables lateral linear displacement. The toothed rod 35 meshes with the convex tooth 331. By adjusting the rotation direction and number of turns of the threaded rod 34, the swing angle of the swing plate 33 can be precisely controlled, thereby adjusting the sanding area of the sandpaper belt 36 on the surface of the cross bar, improving the flexibility and accuracy of sanding position control, and adapting to the surface treatment requirements of cross bars with different configurations.
[0036] The working principle of this utility model is as follows: The crossbar to be ground is placed on the upper surface of two supporting V-blocks 15, and one end is in contact with the output shaft of the rotary drive motor 13. Then, the crossbar is pressed by the push pressing mechanism 2, so that the rotary drive motor 13 drives the crossbar to be ground to rotate. Due to the presence of the spring 25, the slider 22 has a force in the direction of the bearing seat 21, so that the pressing plate 24 will move away from the bearing seat 21 when there is no force. During installation, the pressing plate 24 can be moved by moving the slider 22. After the crossbar is installed in place, it will rotate automatically. Then, the grinding mechanism 3 will carry out the grinding work. The grinding mechanism 3 can move along the trajectory of the first track rod 11 to adjust the grinding position, and rotate the threaded rod 34 to control the lateral movement of the toothed rod 35. Then, the angle of the swing plate 33 is controlled by the meshing of the toothed rod 35 and the convex tooth 331, and then the sandpaper belt 36 is controlled to contact the crossbar to achieve grinding. This structure can adapt to the grinding work of crossbars of different lengths and sizes, and can flexibly control the grinding position, improving the practicality of the equipment.
[0037] During the polishing process, the second slide plate 4 and the polishing mechanism 3 are fixedly connected by the connecting plate 5. Therefore, when the polishing mechanism 3 moves laterally, the second slide plate 4 moves synchronously, ensuring that the suction box 41 can remove dust from the polishing position. This structure ensures that the suction position always corresponds to the polishing position, thus ensuring the dust removal effect.
[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
