Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, and particularly to a feeding mechanism of a double-sided grinding machine. Background Art

[0002] A grinding machine is a machine tool that uses a grinding tool to grind the surface of a workpiece. Most grinding machines use a high-speed rotating grinding wheel for grinding, and a few use other grinding tools such as oilstones and abrasive belts and free abrasives for processing, such as honing machines, superfinishing machines, abrasive belt grinding machines, grinding machines, and polishing machines.

[0003] Magnetic steels are mainly used in various fields such as sensors, instruments, electronics, electro-mechanics, medical treatment, teaching, automobiles, aviation, and military technology. According to different metal component compositions of magnetic steels, their magnetic properties are also different, and thus their uses are also different. At present, magnetic steels are manufactured by powder metallurgy. The surface roughness of the products formed by powder metallurgy often does not meet the requirements, so the outer surface needs to be ground by a grinding device. At present, magnetic steels are generally manufactured by powder metallurgy, and after production, they are ground by a grinding machine to make their thickness, length, or width dimensions meet the design requirements.

[0004] In the existing grinding machine structure, the feeding mechanism usually includes a feeding channel composed of feeding clamping blocks and upper and lower baffle plates, and feeding guide wheels are arranged on both sides of the inlet end of the feeding channel to drive the workpieces to move successively towards the end where the grinding wheel is located, so as to realize the function of automatic feeding. However, in the current structure, as disclosed in a feeding mechanism of an end face grinding machine in patent CN213258883U, the driving mechanism for driving two feed wheels to rotate is arranged at the lower end of the machine frame. The first gear shaft in the middle structure needs to pass through the top plate of the machine frame to be in transmission connection with the gear transmission assembly of the feed wheel. This structure requires the opening of an installation hole in the top plate of the machine frame, and there is a potential water leakage hazard at the installation hole position in the later stage; in addition, in this structure, when the workpiece specifications change, the installation bracket needs to be adjusted to adjust the width of the feeding channel, and at the same time, the position of the feed wheel needs to be adjusted. This separately adjustable structure not only increases the adjustment mechanism and cost, but also affects the working efficiency. Summary of the Utility Model

[0005] To overcome at least one defect in the above prior art, the utility model provides a feeding mechanism of a double-sided grinding machine. The workpiece driving structure is convenient to install, does not need to damage the top plate of the machine frame, and can synchronously adjust the position of the feed wheel while realizing the adjustment of the width of the feeding channel, without separate adjustment, simplifies the adjustment mechanism, and reduces the cost.

[0006] The utility model provides a feeding mechanism for a double-sided grinding machine, which comprises two mounting seats symmetrically arranged left and right and connected to the grinding machine frame and capable of adjusting positions left and right.

[0026] First of all, those skilled in the art should understand that these embodiments are only used to explain the technical principles of the embodiments of the present application, and are not intended to limit the protection scope of the embodiments of the present application. Those skilled in the art can make adjustments according to needs to adapt to specific application scenarios.

[0027] In the description of the embodiments of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "fixed" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0028] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Referring to Figures 1 to 6 As shown, an embodiment of the present application discloses a feeding mechanism for a double-sided grinding machine, including two mounting seats 1 that are symmetrically arranged left and right and can be adjusted in position left and right on the grinding machine frame. Each mounting seat 1 is connected with a feeding clamp block 2 extending in the front-rear direction of the grinding machine frame. A feeding channel is formed between the feeding clamp blocks 2 of the two mounting seats 1. A grinding head assembly 29 is arranged at the rear end of the feeding channel on the grinding machine frame. Additionally, a vertically liftable upper baffle 3 and a lower baffle 4 are arranged in the inner cavity of the feeding channel. At least one mounting seat 1 is provided with a driving assembly for driving the upper baffle 3 and the lower baffle 4 to lift. When the size specification of the workpiece changes, the positions of the upper baffle 3 and the lower baffle 4 are adjusted through the driving assembly to ensure accurate grinding of the workpiece in the grinding head assembly 29. In order to realize automatic feeding of the workpiece, in this structure, feeding wheel 5 assemblies are also arranged on the two mounting seats 1, respectively located on both sides of the feeding channel and used to drive the workpiece to move towards the grinding head assembly 29.

[0030] In this embodiment, the feeding wheel 5 assembly includes a feeding wheel 5 and a motor unit. The two motor units are respectively connected to the two mounting seats 1 and can be adjusted in position left and right. The two feeding wheels 5 are respectively connected to the output shafts of the two motor units, and the rotation directions of the two feeding wheels 5 are opposite. Grooves communicating with the feeding channel are arranged on both feeding clamp blocks 2. The two feeding wheels 5 are partially accommodated in the grooves, and the radially outer walls of the feeding wheels 5 protrude from the inner side walls of the two feeding clamp blocks 2, that is, the feeding wheels 5 on both sides respectively abut against the two side walls of the workpiece. The feeding wheels 5 are generally made of rubber material. When the two feeding wheels 5 rotate in opposite directions, under the action of friction, the workpiece moves backward along the feeding channel to the grinding head assembly 29 for grinding.

[0031] Preferably, in the above structure, both the upper baffle 3 and the lower baffle 4 include two parts that cooperate left and right. Vertically arranged columns 6 are connected to both mounting seats 1. The upper baffle 3 and the lower baffle 4 on the left and right sides in the feeding channel are respectively connected to the left and right columns 6, and driving assemblies for driving the corresponding upper and lower baffles 4 to move up and down are arranged on both columns 6. Additionally, the two feeding clamp blocks 2 are respectively fixedly connected to the two columns 6.

[0032] Additionally, referring to the Figure 4 and 5 , taking the mounting seat 1, column 6 and other structures on the right side of the feeding channel as an example for specific description:

[0033] On the outer wall of the vertical column 6 (the illustrated direction is the front wall), there are inwardly concave guiding sliding grooves 7 extending along its axial direction. An upper sliding block 8 and a lower sliding block 9 are slidably fitted in the guiding sliding grooves 7. The top and bottom of the vertical column 6 are respectively rotatably connected with an upper screw rod 10 and a lower screw rod 11 extending along its axial direction. Moreover, the upper screw rod 10 and the lower screw rod 11 are respectively in threaded cooperation with the upper sliding block 8 and the lower sliding block 9. The upper sliding block 8 and the lower sliding block 9 on the vertical column 6 are respectively connected with the upper baffle plate 3 and the lower baffle plate 4 on the corresponding side (right side) in the feeding channel. When it is necessary to adjust the height position of the upper baffle plate 3 or the lower baffle plate 4, by rotating the corresponding upper screw rod 10 or lower screw rod 11, the height position of the upper sliding block 8 or the lower sliding block 9 can be adjusted. The structure is simple and the adjustment is convenient. Further, in this structure, a manual knob is respectively connected to the top of the upper screw rod 10 and the bottom of the lower screw rod 11, which is convenient for rotating the corresponding screw rod. Of course, in some other embodiments, the upper screw rod 10 and the lower screw rod 11 can also be driven by a driver such as a servo motor to realize the automatic adjustment of the height position of the upper baffle plate 3 or the lower baffle plate 4. In this embodiment, the driving assembly includes the above-mentioned upper screw rod 10, lower screw rod 11, upper sliding block 8 and lower sliding block 9. Connecting pieces 30 for respectively fixing the upper baffle plate 3 and the lower baffle plate 4 are further connected to the upper sliding block 8 and the lower sliding block 9.

[0034] More specifically in the above structure, the guiding sliding grooves 7 opened on the front wall of the vertical column 6 are vertically through, which is convenient for processing. Therefore, in order to realize the connection of the upper screw rod 10 and the lower screw rod 11, an upper fixing plate and a lower fixing plate are respectively connected to the top and bottom of the vertical column 6. The upper screw rod 10 and the lower screw rod 11 are respectively rotatably connected to the upper fixing plate and the lower fixing plate. And, vertically communicating threaded holes are respectively arranged on the upper sliding block 8 and the lower sliding block 9. The lower end of the upper screw rod 10 is in spiral cooperation with the threaded hole on the upper sliding block 8, and the upper end of the lower screw rod 11 is in spiral cooperation with the threaded hole on the lower sliding block 9.

[0035] In addition, refer to the appendix Figure 5 and 6, in order to further ensure the smooth lifting of the upper slider 8 and the lower slider 9 in the guiding chute 7, a wedge-shaped positioning groove 12 is provided at the open end of the guiding chute 7 and on one side in its width direction, and a rectangular fitting groove 13 is provided on the other side. A rectangular pressing plate 14 is connected in the fitting groove 13. Specifically, the pressing plate 14 is connected in the fitting groove 13 by a plurality of connecting screws 31. A plurality of positioning screws 32 are also connected to the outer wall of the column 6, and each positioning screw 32 is pressed and positioned on the side wall of the pressing plate 14 to prevent the pressing plate 14 from detaching from the fitting groove 13 due to the loosening of the connecting screws 31, which may cause the upper slider 8 or the lower slider 9 to tilt during the lifting process and jam with the corresponding screw. In the above structure, a positioning inclined surface 15 is provided on the side of the pressing plate 14 close to the upper slider 8 or the lower slider 9; correspondingly, positioning convex blocks 16 are provided on both sides in the width direction of the upper slider 8 and the lower slider 9. One of the positioning convex blocks 16 is slidably fitted in the positioning groove 12, that is, the shape of this positioning convex block 16 is also wedge-shaped, and a guiding inclined surface for cooperating with the positioning inclined surface 15 is provided on the other positioning convex block 16. When the pressing plate 14 moves along the depth direction of the fitting groove 13, under the action of the guiding inclined surface, the upper slider 8 and the lower slider 9 move towards one side of the positioning groove 12, thereby realizing the adjustment of the sliding friction resistance of the upper slider 8 and the lower slider 9 up and down.

[0036] On the other hand, in the above structure, an opening groove 17 communicating with the threaded hole is provided on one side in the width direction of the upper slider 8 and the lower slider 9, and an adjusting screw 18 for adjusting the gap of the opening groove 17 is connected in the thickness direction of the upper slider 8 and the lower slider 9. By screwing the adjusting screw 18, the tightness of the movement of the upper screw 10 and the lower screw 11 in the corresponding threaded holes can be adjusted, avoiding the defects of inaccurate and unstable adjustment of the upper slider 8 and the lower slider 9 due to the wear of the threaded mating surface.

[0037] In this embodiment, referring to the attached Figure 2 and 3 it can be seen that the left-right adjustment of the position of the mounting seat 1 means that first slider carriages 20 are respectively connected to both sides of the feed channel on the grinding machine frame. The first bottom plate 19 of the first slider carriage 20 is connected to the outer wall of the drive box 28 of the grinding machine frame. The mounting seat 1 is connected to the first slider 20 of the first slider carriage 20, and a first handwheel 21 for driving the slider to slide is connected to the first bottom plate 19. By rotating the first handwheel 21 forward and backward, under the driving action of the lead screw inside the first slider carriage 20, the first slider 20 can slide left and right, and then drive the mounting seat 1 to slide accordingly, thereby driving the column 6 and the motor unit to move left and right synchronously. The structure is simple and the adjustment is convenient, and the feed clamping block 2 and the feed wheel 5 do not need to be adjusted separately. Therefore, after the position of the feed wheel 5 is adjusted in place, its position in the groove can always be maintained at the set position. After the workpiece specification changes, only the position of the mounting seat 1 needs to be adjusted.

[0038] Similarly, the motor unit can be adjusted left and right in position, which means that a second slider carriage 23 is connected to the mounting base 1, and the second base plate 22 of the second slider carriage 23 is connected to the mounting base 1. The motor unit is connected to the second slider 23 of the second slider carriage 23, and a second handwheel 24 for driving the second slider 23 to slide is connected to the second base plate 22.

[0039] In this embodiment, referring to the attached Figure 2 and 3 , the motor unit includes a gearbox 25 connected to the second slider 23. One side of the gearbox 25 is connected to a motor 26, and the power input end of the gearbox 25 is connected to the output shaft of the motor 26. The power output end of the gearbox 25 is connected to a vertically extending power shaft 27, and the feed wheel 5 is connected to the upper end of the power shaft 27. In this structure, the driving component is directly arranged above the top plate of the grinding machine frame, without the need to damage the top plate, which is convenient for installation and later maintenance.

[0040] In the description of the present application, the descriptions referring to the terms "this embodiment", "some embodiments", etc. mean that the specific features, mechanisms, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, mechanisms, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0041] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present application should be covered by the protection scope of the present application.
