Description

Technical Field

[0001] This utility model relates to the field of port polishing technology, and in particular to a fixed support for a port polishing machine. Background Technology

[0002] Existing port grinding machines use fixed supports to precisely position the workpiece to be ground (such as pipe ports, mechanical component connection ports, etc.) in the grinding area of ​​the machine during the port grinding process, providing stable support and ensuring that the workpiece does not move or shake during grinding. However, in use, existing equipment can only adapt to workpieces within a specific size range. For small-sized precision port components, if the clamping point of the fixed support is large, it may not be able to accurately position and firmly clamp the workpiece, causing the workpiece to easily shift during grinding and affecting the grinding accuracy. For large-sized pipe ports, if the clamping structure of the fixed support cannot be effectively expanded to adapt to its size, it may not be able to provide sufficient clamping force, which also affects the grinding quality. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a fixed support for a port grinding machine. When clamping, the position of the longitudinal slider can be moved by rotating the screw, and then the position of the side clamping plates can be moved so that the two side clamping plates are closer to or further away from the central clamping plate. When they are closer, the clamping point is smaller, which is convenient for clamping small-sized workpieces, and vice versa, which is convenient for clamping large-sized workpieces. It can easily adapt to workpieces of various sizes, whether it is a small-sized precision port component or a large-sized pipe port, etc., which can be firmly clamped, improving the versatility of the fixed support and reducing the trouble of frequently changing clamps due to differences in workpiece size.

[0004] This utility model also provides a fixed support for a port grinding machine as described above, comprising: a base plate, a processing table fixedly connected to the upper surface of the base plate, transverse slide rails fixedly connected to two opposite side surfaces of the processing table, transverse sliders slidably connected to the inner surfaces of the two transverse slide rails, a longitudinal slide rail fixedly connected to the upper surface of the transverse sliders, a fixing block fixedly connected to the inner surfaces of the two longitudinal slide rails, a bracket first fixedly connected to the upper surface of the fixing block, a screw first threadedly connected to the inner surface of the bracket first, a central clamping plate rotatably connected to one end of the screw first, two longitudinal sliders slidably connected to the inner surface of the longitudinal slide rails, the two longitudinal sliders slidably connected to both sides of the fixing block, a screw third rotatably connected to two opposite side surfaces of the fixing block, the screw third threadedly connected to the longitudinal slider, a bracket second fixedly connected to the upper surface of the longitudinal slider, a screw second threadedly connected to the bracket second, and a side clamping plate rotatably connected to one end of the screw second.

[0005] According to the present invention, a fixed support for a port grinding machine is provided, wherein a double-ended lead screw is rotatably connected through the inner surfaces of the two transverse slide rails and the processing table, and the two transverse slide blocks are threadedly connected to the double-ended lead screw.

[0006] According to the present invention, a fixed support for a port grinding machine is provided, wherein a second motor is fixedly connected to the side surface of the transverse slide rail, and the double-headed lead screw is driven by the second motor.

[0007] According to the present invention, a fixed support for a port grinding machine is provided, wherein the other end of each of the screws one, two, and three is fixedly connected to a knob, and the knob is provided with an anti-slip groove.

[0008] According to the present invention, a fixed support for a port grinder is provided, wherein a connecting frame is fixedly connected to the rear surface of the side clamp, and a rotating shaft is fixedly connected to one end of the second screw, and the rotating shaft is rotatably connected to the inner surface of the connecting frame.

[0009] According to the present invention, a fixed support for a port grinding machine is provided, wherein a fixed frame is fixedly connected to the upper surface of the base plate, and a hydraulic push rod is fixedly connected to the lower surface of the fixed frame.

[0010] According to the present invention, a fixed support for a port grinding machine is provided, wherein a motor is fixedly connected to the lower end of the hydraulic push rod, and a grinding disc is fixedly connected to the output end of the motor.

[0011] According to the present invention, a fixed support for a port grinding machine is provided, wherein a pad is fixedly connected to the lower surface of the base plate, and a mounting plate is fixedly connected to the lower surface of the pad.

[0012] Compared with existing technologies, this port grinding machine uses a fixed support. During clamping, the position of the longitudinal slider can be moved by rotating the screw, which in turn moves the position of the side clamps. This allows the two side clamps to move closer to or further away from the central clamp. When they are closer, the clamping point is smaller, making it easier to clamp small-sized workpieces, and vice versa, making it easier to clamp large-sized workpieces. It can easily adapt to workpieces of various sizes, whether they are small precision port components or large pipe ports, they can be clamped securely. This improves the versatility of the fixed support and reduces the trouble of frequently changing clamps due to differences in workpiece size. Attached Figure Description

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figures 1-4 This utility model provides a fixed support for a port grinding machine, comprising: a base plate 10, a pad 4 fixedly connected to the lower surface of the base plate 10, a mounting plate 5 fixedly connected to the lower surface of the pad 4, a fixing frame 3 fixedly connected to the upper surface of the base plate 10, a hydraulic push rod 6 fixedly connected to the lower surface of the fixing frame 3, a motor 1 fixedly connected to the lower end of the hydraulic push rod 6, and a grinding disc 2 fixedly connected to the output end of the motor 1.

[0022] Specifically: The lower end of the hydraulic push rod 6 is fixedly connected to a motor 1, and the output end of the motor 1 is fixedly connected to a grinding disc 2. When the hydraulic push rod 6 works, it can push the motor 1 to move downward, so that the grinding disc 2 is close to the workpiece end placed on the processing table 11 to achieve a suitable grinding distance. The extension and retraction of the hydraulic push rod 6 can precisely control the distance between the grinding disc 2 and the workpiece to adapt to the grinding requirements of workpiece ends of different thicknesses. After the motor 1 starts, its output end drives the grinding disc 2 to rotate at high speed. Under the action of the hydraulic push rod 6, the grinding disc 2 contacts the workpiece end. The high-speed rotation of the grinding disc 2 grinds the workpiece end, removing uneven parts, burrs, etc., to achieve the purpose of grinding.

[0023] A processing table 11 is fixedly connected to the upper surface of the base plate 10. A transverse slide rail 15 is fixedly connected to the two opposite side surfaces of the processing table 11. A transverse slider 25 is slidably connected to the inner surface of the two transverse slide rails 15 and the inner surface of the processing table 11. A double-ended lead screw 26 is rotatably connected through the two transverse slide rails 15 and the double-ended lead screw 26. A motor 26 is fixedly connected to the side surface of one of the transverse slide rails 15. The double-ended lead screw 26 is driven by the motor 26.

[0024] Specifically: Transverse slide rails 15 are fixedly connected to the two opposite side surfaces of the processing table 11. A horizontal slider 25 is slidably connected inside the transverse slide rails 15. A double-ended lead screw 26 is rotatably connected through the two transverse slide rails 15 and the inner surface of the processing table 11. The horizontal slider 25 and the double-ended lead screw 26 are threadedly connected. When the motor 16 drives the double-ended lead screw 26 to rotate, due to the threaded engagement between the double-ended lead screw 26 and the horizontal slider 25, the two horizontal sliders 25 will move in opposite directions or away from each other along the transverse slide rails 15. This design is used to drive the side clamping plate 19 and the center clamping plate 12 to move synchronously, so as to achieve the function of clamping from both sides of the workpiece to the middle, thereby firmly clamping the workpiece on the processing table 11.

[0025] The upper surface of the horizontal slider 25 is fixedly connected to the longitudinal slide rail 24. The inner surfaces of the two longitudinal slide rails 24 are fixedly connected to the fixing blocks 17. The upper surface of the fixing blocks 17 is fixedly connected to the bracket 18. The inner surface of the bracket 18 is threadedly connected to the screw 14. One end of the screw 14 is rotatably connected to the central clamping plate 12.

[0026] Specifically: The fixing block 17 is located inside the longitudinal slide rail 24 and between the two longitudinal sliders 23. A bracket 18 is fixedly connected to the upper surface of the fixing block 17. A screw 14 is threaded through the bracket 18. One end of the screw 14 is rotatably connected to the center clamping plate 12. When the knob 8 at one end of the screw 14 is rotated, the screw 14 rotates inside the bracket 18. Due to the rotational connection between the screw 14 and the center clamping plate 12, the center clamping plate 12 will move longitudinally along the longitudinal slide rail 24. By rotating the screw 14, the position of the center clamping plate 12 can be finely adjusted to further and more precisely clamp the center part of the workpiece, ensuring that the workpiece will not undergo longitudinal displacement during the grinding process.

[0027] Two longitudinal sliders 23 are slidably connected to the inner surface of the longitudinal slide rail 24. The two longitudinal sliders 23 are slidably connected to both sides of the fixed block 17. The two opposite side surfaces of the fixed block 17 are rotatably connected to screws 3 7. Screws 3 7 are threadedly connected to the longitudinal sliders 23. The upper surface of the longitudinal sliders 23 is fixedly connected to bracket 2 22. Screws 2 13 are threadedly connected to bracket 2 22. One end of screws 2 13 is rotatably connected to a side clamp 19. The rear surface of the side clamp 19 is fixedly connected to a connecting frame 20. One end of screws 2 13 is fixedly connected to a rotating shaft 21. The rotating shaft 21 is rotatably connected to the inner surface of the connecting frame 20. The other ends of screws 1 14, screws 2 13, and screws 3 7 are all fixedly connected to knobs 8. The knobs 8 are provided with anti-slip grooves 9.

[0028] Specifically: A longitudinal slide rail 24 is fixedly connected to the upper surface of the horizontal slider 25. Two longitudinal sliders 23 are slidably connected inside the longitudinal slide rail 24. Screws 3 7 are rotatably connected to the two opposite side surfaces of the fixed block 17. Screws 3 7 are threadedly connected to the longitudinal sliders 23. When the knob 8 at one end of screws 3 7 is rotated, screws 3 7 rotates. Due to the threaded engagement between screws 3 7 and longitudinal sliders 23, the longitudinal sliders 23 will move towards or away from each other along both sides of the fixed block 17 inside the longitudinal slide rail 24. A bracket 22 is fixedly connected to the upper surface of the longitudinal sliders 23. Screws 2 13 are threadedly connected to bracket 22. One end of screws 2 13 is rotatably connected to a side clamping plate 19. When the knob 8 at one end of screws 2 13 is rotated, screws 2 13 rotates, causing the side clamping plate 19 to move closer to or away from the central clamping plate 12. When it moves closer, the clamping point shrinks, making it easier to clamp small-sized workpieces. Conversely, it makes it easier to clamp large-sized workpieces. It can easily adapt to workpieces of various sizes.

[0029] Working Principle: In operation, first, the workpiece end to be ground is placed on the processing table 11. Motor 2 16 drives the double-ended lead screw 26 to rotate, causing the two horizontal sliders 25 to move in opposite directions along the transverse slide rail 15. This causes the side clamping plates 19 and the center clamping plate 12 to move synchronously, initially clamping the workpiece from both sides towards the center and positioning it. Then, the knob 8 of screw 1 14 is rotated to fine-tune the position of the center clamping plate 12, further precisely clamping the center part of the workpiece. Next, according to the specific dimensions of the workpiece end, the knob 8 of screw 3 7 is rotated first to adjust the position of the vertical slider 23, and then the knob 8 of screw 2 13 is rotated to adjust the position of the side clamping plates 19, ensuring that the two side clamping plates 19 stably adhere to the surface of the workpiece, firmly clamping the workpiece end and ensuring that the workpiece will not move or shake during the grinding process.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
