Technical Field

[0001] This utility model relates to the field of grinding machine technology, and in particular to an adjustable grinding worktable for a grinding machine. Background Technology

[0002] A grinding wheel machine is a commonly used industrial piece of equipment, widely used for grinding, deburring, and cleaning small parts, including cutting tools and other tools. The outer surface of metal products needs to be ground to improve its integrity. Grinding ring-shaped metal parts typically requires manual operation by the worker, using the grinding wheel machine's grinding mechanism to polish the outer surface. The grinding table is a crucial component of the grinding wheel machine, primarily used to support the machine and provide a stable operating platform. Some grinding tables can also support the ring-shaped metal parts being ground, allowing workers to rest their hands during grinding and thus reducing physical strain.

[0003] However, the common grinding wheel machine grinding table is used to assist the operator in temporarily placing the workpiece during the grinding process. Because the outer surface of the ring-shaped metal workpiece is being ground, the operator needs to frequently change the hand position, which not only consumes physical strength but also affects the grinding progress. In view of this, we propose an adjustable grinding wheel machine grinding table. Utility Model Content

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example

[0021] like Figures 1 to 3 As shown, this utility model proposes an adjustable grinding table for a grinding machine, including a grinding machine body 1, a controller 2, and a first support 3. The controller 2 is fixedly installed on the front-view wall of the support structure of the grinding machine body 1. The side wall of the top plate structure of the first support 3 is fixedly connected to the side wall of the support structure of the controller 2. The second support 4 is set at the top plate structure of the first support 3. The first cylinder 5 is fixedly installed on the bottom wall of the top plate of the first support 3. The output end of the first cylinder 5 is connected to the inner surface wall of the second support 4, which facilitates the adjustment of the position of the second support 4 and is beneficial for subsequent adjustment of the distance between the second support 4 and the grinding part of the grinding machine body 1 according to the diameter of the annular metal part. The notch opened on the top plate structure of the second support 4 corresponds to the position of the grinding disc structure of the grinding machine body 1, so as to avoid affecting the grinding operation when approaching the grinding machine body 1. The bottom wall of the vertical structure of the second support 4 is connected to the first cylinder 5. The two first cylinders 5 are respectively set into the symmetrically opened limiting grooves on the top plate of the first support 3, which guide the second support 4 in the lateral movement state.

[0022] Furthermore, the limiting rotary seat 10 is embedded in the limiting rotary opening on the top wall of the second bracket 4 and is adapted to the limiting rotary opening to assist the limiting rotary seat 10 in rotating at the top of the second bracket 4; the positioning component 7 is installed on the limiting rotary seat 10, and the gear ring 9 is fixedly sleeved on the outer surface wall of the limiting rotary seat 10 and is set inside the second bracket 4 to facilitate subsequent rotation of the limiting rotary seat 10; the drive component 8 is installed on the bottom wall of the top plate of the second bracket 4, and the drive component 8 includes a motor frame 81, a motor 82, a rotating shaft 83, and a gear 84. The motor frame 81 is L-shaped. The top wall of the vertical structure of the motor frame 81 is fixedly connected to the bottom wall of the top plate of the second bracket 4. The motor 82 is fixedly installed on the top wall of the horizontal structure of the motor frame 81, and the motor frame 81 supports the motor 82. The bottom end of the rotating shaft 83 is connected to the output end of the motor 82. The gear 84 is sleeved on the outer surface wall of the rotating shaft 83 and meshes with the gear ring 9. This facilitates the rotation of the gear ring 9 under the drive of the motor 82, in conjunction with the rotating shaft 83 and the gear 84, thereby providing power for the subsequent rotation of the ring-shaped metal part.

[0023] Furthermore, the positioning component 7 includes a second cylinder 70, a movable block 71, a first hinge seat 72, a hinge rod 73, a second hinge seat 74, a clamping member 75, a pressure plate 76, a screw 77, and a slider 78. The second cylinder 70 is fixedly installed on the bottom wall of the limiting rotary seat 10, and the output end of the second cylinder 70 is connected to the top wall of the movable block 71 for adjusting the height of the movable block 71. Multiple first hinge seats 72, hinge rods 73, and second hinge seats 74 are arranged in a ring. Multiple first hinge seats 72 are respectively installed on the four walls of the movable block 71, and multiple second hinge seats 74 are located below the limiting rotary seat 10. Multiple hinge rods 73 have auxiliary holes at both ends. At both ends, the first hinge seat 72 and the second hinge seat 74 are hinged by auxiliary holes. The bottom wall of the multiple clamping parts 75 is inserted into the first slide rail opened in the annular array on the limiting rotary seat 10 and is fixedly connected to the top wall of the multiple second hinge seats 74. This makes it easier to expand or contract the clamping parts 75 during the extension and retraction of the output end of the second cylinder 70, so as to clamp and position the annular metal parts with different inner diameters, expand the scope of application and improve practicality. The multiple sliders 78 are grouped in pairs, and the two sliders 78 in each group are symmetrically installed on the two side walls of the clamping parts 75 and embedded in the symmetrically opened slide grooves on the two side walls of the first slide rail, which assists the clamping parts 75 in moving at the first slide rail.

[0024] Multiple pressure plates 76 are partially set into the second slides opened on multiple clamping members 75. The threaded holes on the pressure plates 76 correspond to the rotating holes opened at the top of the second slides and the rotating grooves opened on the bottom wall of the second slides. Bearings are embedded in the rotating grooves. The bottom end of the screw 77 passes through the rotating holes and threaded holes and is inserted into the rotating grooves, so that the bearings are sleeved on the outer surface wall of the screw 77, which helps the screw 77 to rotate on the clamping member 75. The rotating screw 77 can adjust the height of the pressure plates 76, which helps to block the top wall of the annular metal part, reduce the upward movement of the annular metal part during subsequent grinding, and improve the stability during positioning.

[0025] In this embodiment, when grinding the outer surface wall of the annular metal part, the annular metal part is placed at the top of the limiting rotating seat 10 and the second bracket 4. The second cylinder 70 drives the movable block 71 to rise and fall. Under the hinge action of the first hinge seat 72, the hinge rod 73, and the second hinge seat 74, the positions of the multiple clamping members 75 are adjusted, allowing the clamping members 75 in the expanded state to clamp and position the annular metal part. Due to the retractable and expandable design of the clamping members 75, it is beneficial to clamp and position annular metal parts with different inner diameters, expanding the scope of application and improving practicality. To prevent the annular metal part from moving up and down during grinding, therefore… Tightening screw 77 adjusts the height of pressure plate 76, allowing it to press against the top wall of the annular metal part, thus improving stability during grinding. When adjustment is needed for the grinding area on the outer surface of the annular metal part, motor 82 drives shaft 83 to rotate gear 84, causing gear ring 9 to rotate with gear 84. This achieves the purpose of rotating and adjusting positioning component 7 mounted on the limiting rotating seat 10, thus completing the rotation adjustment of the annular metal part. This eliminates the need for operators to hold the annular metal part, improving operational safety, reducing labor intensity, and increasing grinding efficiency.

[0026] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
