Description

Technical Field

[0001] The invention discloses an adaptive gravity floating grinding device, belonging to the technical field of grinding equipment. Background Art

[0002] Grinding is a finishing process that uses high-speed rotating grinding wheels and other abrasive tools to cut the surface of the workpiece to improve the surface quality of the workpiece. Grinding is usually performed using a grinder, where the workpiece is clamped and ground by the high-speed rotating abrasive tool on the grinder.

[0003] For workpieces with irregular deformation, automatic grinding needs to be programmed according to the shape of the workpiece. Since the shapes of each workpiece are different, each workpiece needs to be programmed separately or the deformation of the workpiece is sensed by electronic induction and then the programming is adjusted. However, these methods cannot achieve automatic grinding well. The efficiency of programming each workpiece separately is extremely low; using electronic control to sense and respond after receiving the signal will cause lag in the process, and the grinding effect is not ideal.

The translation motor is fixed on the mounting frame, the translation rack is horizontally arranged, the translation gear is installed on the output shaft of the translation motor, and the translation gear is meshed with the translation rack.

[0007] Furthermore, the transmission assembly includes a balancing chain and a sprocket, the sprocket is rotatably mounted on the top of the mounting frame, the middle portion of the balancing chain is located on the upper side of the sprocket and meshes with it, and the two ends of the balancing chain are respectively connected to the weight balancing assembly and the grinding assembly.

[0008] Furthermore, two sprockets are arranged side by side and at intervals.

[0010] Furthermore, pulleys are fixedly mounted on the output shaft of the grinding motor and the grinding wheel, and the two pulleys are connected by a transmission belt.

[0011] Furthermore, it also includes a tensioning frame and a tensioning bolt. The tensioning frame and the balancing frame can slide relative to each other. The tensioning bolt is threadedly connected to the balancing frame. The tensioning bolt pushes the tensioning frame away from the grinding motor.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0021] Figure 1-Figure 6 It is the best embodiment of the utility model, and the following Figure 1-Figure 6 The utility model is further described.

[0022] The adaptive gravity floating grinding device comprises a translation device, a mounting frame 2, a grinding component, a transmission component and a weight balancing component. The mounting frame 2 is mounted on the translation device, the grinding component and the weight balancing component are respectively arranged on both sides of the mounting frame 2, the transmission component is mounted on the mounting frame 2, and the transmission component is connected to the grinding component and the weight balancing component at the same time. The balancing component of the adaptive gravity floating grinding device can balance the weight of the grinding component. When the grinding component grinds the top surface of the workpiece, since the weight of the grinding component has been balanced, the grinding component can be adjusted in real time according to the shape of the top of the workpiece, so as to ensure a good grinding effect on the workpiece, which can not only solve the problem of low efficiency of individual programming, but also avoid the problem of lag in adjustment.

[0023] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.

[0024] Specifically, Figure 1-3 As shown, the adaptive gravity floating grinding device also includes a crossbeam 1, which is horizontally arranged, and a connecting frame is arranged on the top of the crossbeam 1 for fixing and installing the device. Translation guide rails 9 are symmetrically fixed on both sides of the bottom of the crossbeam 1, and translation slides are arranged on both sides of the top of the mounting frame 2, and each translation slide is slidably installed on the translation guide rails 9 on the corresponding side.

[0025] The translation device includes a translation motor 5, a translation rack 12 and a translation gear 13. The translation rack 12 is fixedly installed on the lower side of the beam 1. The translation rack 12 is arranged parallel to the translation guide rail 9 and is arranged between the translation guide rails 9 on both sides. The translation motor 5 is installed on the mounting frame 2. The translation gear 13 is fixedly installed on the output shaft of the translation motor 5, and the translation gear 13 is meshed with the translation rack 12.

[0026] The translation motor 5 drives the translation gear 13 to rotate, and then cooperates with the translation rack 12, thereby driving the mounting frame 2 to reciprocate along the translation guide rail 9.

[0027] The self-adaptive gravity floating grinding device also includes a balancing frame 6, and vertical balancing rails 17 are symmetrically arranged on both sides of the mounting frame 2. Balancing slides are arranged on both sides of the balancing frame 6, and each balancing slide can be slidably mounted on the balancing rail 17 on the corresponding side. The grinding assembly is mounted on the balancing frame 6, the transmission assembly is connected to the balancing frame 6, and the weight of the grinding assembly is balanced by the weight balancing assembly.

[0028] The transmission assembly includes a balancing chain 3 and a sprocket 4. The sprocket 4 is rotatably mounted on the top of the mounting frame 2. The middle of the balancing chain 3 is arranged on the upper side of the sprocket 4. The balancing chain 3 is meshed with the sprocket 4. The two ends of the balancing chain 3 are respectively connected to the weight balancing assembly and the balancing frame 6, thereby balancing the weight of the grinding assembly. In this embodiment, two sprockets 4 are arranged side by side and at intervals, and each sprocket 4 is meshed with the balancing chain 3.

[0029] The weight balancing component is a counterweight 11, which is disc-shaped and has an opening on one side of the counterweight 11 to facilitate the installation of the counterweight 11. By changing the number of counterweights 11, the weight of the counterweight 11 is made the same as the weight of the balance frame 6 and the grinding component, thereby ensuring that the grinding component can be adaptively adjusted according to the shape of the top of the workpiece.

[0030] In this embodiment, transmission components are disposed on both sides of the mounting frame 2, and each transmission component is connected to an independent weight balancing component.

[0031] The grinding assembly includes a grinding motor 7 and a grinding wheel 8. A tensioning frame 14 is installed at the bottom of the balancing frame 6 in a liftable manner. The grinding motor 7 is installed on the balancing frame 6. The grinding wheel 8 is rotatably installed on the tensioning frame 14. Pulleys are fixedly installed on the output shafts of the grinding wheel 8 and the grinding motor 7, and the two pulleys are connected by a transmission belt 10.

[0032] The grinding motor 7 drives the grinding wheel 8 to rotate through the transmission belt 10, and grinds the top surface of the workpiece through the grinding wheel 8. Further, the grinding wheel 8 is located at the bottom of the tensioning frame 14 to avoid being hindered when the grinding wheel 8 grinds the workpiece.

[0033] The balancing frame 6 and the tensioning frame 14 are connected by fixing bolts. Vertical long holes are symmetrically arranged on both sides of the lower part of the balancing frame 6. The fixing bolts can slide through the long holes and the tensioning frame 14 in turn and are connected with fixing nuts, so that the tensioning frame 14 can be raised and lowered along the balancing frame 6 and the tensioning frame 14 can also be fixed.

[0034] A vertical tensioning bolt 19 is threadedly connected to the balance frame 6. The tensioning bolt 19 is located on the upper side of the tensioning frame 14. Two tensioning bolts 19 are arranged side by side and at intervals. The bottom of the tensioning bolt 19 is supported on the tensioning frame 14. The tensioning bolt 19 pushes the tensioning frame 14 to move downward, so that the tensioning frame 14 moves away from the grinding motor 7, thereby tightening the transmission belt 10.

[0035] Each tensioning bolt 19 is threadedly connected with a locking nut 15 , and the locking nut 15 presses the balance frame 6 , thereby locking the tensioning bolt 19 to prevent the tensioning bolt 19 from rotating freely during operation.

[0036] like Figure 4-6 As shown: the adaptive gravity floating grinding device also includes a limiting component for limiting the balance frame 6, and the limiting component is installed on the mounting frame 2.

[0037] The limit assembly includes an upper limit block 16 and a lower limit block 18, both of which are installed on the mounting frame 2, the upper limit block 16 is spaced apart on the upper side of the lower limit block 18, and an outwardly protruding limit portion is provided on the balance frame 6, the limit portion is located between the upper limit block 16 and the lower limit block 18, thereby realizing the limitation of the balance frame 6.
