Description
Technical Field
[0001] This utility model relates to the technical field of grinding and positioning components, specifically a grinding and positioning component for mechanical parts. Background Technology
[0002] Mechanical parts are the basic functional units that make up mechanical equipment, and they usually have specific shapes and machining accuracy requirements. During machining, grinding is mainly used to remove burrs, correct surface defects, or improve fit accuracy to meet assembly and usage requirements. During grinding, in order to avoid machining deviations or surface damage caused by displacement or force deflection of parts, positioning components are usually needed to achieve stable clamping and precise position control, ensuring that the grinding tool and the machined surface always maintain correct contact, thereby ensuring machining quality and efficiency.
[0003] According to a relevant patent (202421362222.3), a mechanical parts grinding and positioning assembly includes: an alloy bracket, with a grinding assembly fixedly mounted on one side of the top of the alloy bracket; and a positioning assembly disposed on the other side of the top of the alloy bracket, the bottom of which has a mounting base fixed to the alloy bracket. The mounting base contains an adjustable blocking structure, which restricts the positioning assembly from moving towards the grinding assembly. This invention, through the blocking structure within the mounting base, can prevent the positioning assembly and the mechanical parts clamped on it from moving towards the grinding assembly, while simultaneously utilizing the blocking... The adjustable position of the stop structure allows for adjustable movement of the positioning component toward the grinding component, resulting in more precise and controllable grinding of mechanical parts, improving operational convenience and grinding accuracy. However, while the adjustable stop structure optimizes single-time positioning accuracy, it has significant limitations in multi-faceted processing scenarios. When grinding the other end of a mechanical part is required, it must be completely removed from the positioning component and re-clamped. This process not only complicates the operation but also carries the risk of reference surface misalignment due to repeated positioning, reducing processing efficiency and making it inconvenient for users. Utility Model Content
[0004] The purpose of this utility model is to provide a positioning component for grinding mechanical parts, so as to solve the problem mentioned in the background art that when it is necessary to grind the other end of the mechanical part, it must be completely disassembled from the positioning component and re-clamped. This process not only makes the operation process cumbersome, but also causes the risk of datum surface offset due to repeated positioning, which reduces processing efficiency and is inconvenient for users.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a mechanical parts grinding and positioning assembly, including a base, a top plate at the upper end of the base, a sleeve at one side of the lower end of the top plate, a clamping groove at the center of one side of the sleeve, a clamping plate at the bottom of the sleeve, a clamping electric cylinder fixedly installed at the center of the bottom of the sleeve, a transmission cavity at one side of the top plate, a motor fixedly installed at one side of the top of the transmission cavity, a rotating rod at one side of the motor, an annular seat fixedly connected to the bottom of the top plate corresponding to the upper end of the sleeve, a rotating disk at the bottom of the annular seat, an annular sliding plate fixedly connected to the center of the outer wall of the rotating disk, an annular sliding groove at the bottom of the inner wall of the annular seat, a driven gear fixedly installed on the surface of the rotating rod corresponding to the inside of the transmission cavity, a driving gear meshing with one side of the driven gear, a moving plate at one side of the sleeve, and a grinding machine at one side of the moving plate.
[0006] Compared with the prior art, the beneficial effects of this utility model are:
[0007] This mechanical parts grinding and positioning assembly, through the design of a drive gear, driven gear, annular seat, rotating disk, annular slide plate, annular groove, rotating rod, and motor, uses a motor to drive the drive gear to rotate, which in turn drives the meshing driven gear and rotating rod to rotate synchronously. This causes the rotating disk, which is fixed to the lower end of the rotating rod, to rotate horizontally within the annular seat. The annular slide plate on the outer wall of the rotating disk slides inside the annular groove, forming a radial limiting structure that effectively suppresses swaying during rotation and ensures the stability of rotational positioning. The clamping sleeve is fixed to the rotating disk through a top connecting block, achieving synchronous rotation. This allows the clamped part to be adjusted to the working position of the grinding machine without disassembling it. This structural combination simplifies multi-faceted processing operations, enabling grinding of both ends of mechanical parts in a single clamping, reducing repeated positioning errors, and significantly improving processing efficiency and positioning accuracy.

[0017] The bottom of the clamping sleeve 3 is fixedly connected to the external of the clamping electric cylinder 4. The center of the bottom of the connecting frame 7 is fixedly connected to the support column 8.

[0018] The top of the rotating rod 25 is movably connected to a bearing fixedly installed on the other side of the top of the transmission cavity 9. The rotating rod 25 reduces rotational friction through the bearing and transmits power from the motor 26 to the rotating disk 13. The outer wall of the annular slide plate 14 penetrates into the interior of the annular groove 15 and slides with the inner wall of the annular groove 15, constraining the radial sway of the rotating disk 13 and ensuring rotational accuracy. The lower end of the rotating rod 25 penetrates into the exterior of the top plate 2 and is fixedly connected to the center of the top of the rotating disk 13. The bottom of the rotating disk 13 is fixedly connected to both sides of the bottom. The bottom of the two first connecting blocks penetrates into the exterior of the annular seat 12 and is fixedly connected to both sides of the top of the clamp 3 respectively. The motor 26 is fixedly connected to the output shaft through its bottom output end. The lower end of the output shaft is fixedly connected to the center of the top of the drive gear 10. The guide rod 16 and the guide sleeve 17 form a horizontal moving guide mechanism to ensure that the moving plate 18 is adjusted along a straight line. The support wheel 24 reduces moving friction, and the handle facilitates manual pushing, together realizing the flexible movement of the grinder 20.
[0019] A horizontal groove is provided on the other side of the bottom of the top plate 2. A guide rod 16 is fixedly installed in the center of the horizontal groove. A guide sleeve 17 is slidably connected to the surface of the guide rod 16 corresponding to the upper end of the movable plate 18. A second connector is fixedly connected to the center of the bottom of the guide sleeve 17. The bottom of the second connector extends through to the outside of the horizontal groove and is fixedly connected to the center of the top of the movable plate 18. A base plate 23 is fixedly connected to the bottom of the movable plate 18. Support wheels 24 are fixedly installed at the four corners of the bottom of the base plate 23. The bottoms of the four support wheels 24 are fixedly connected to the top of the base 1. A handrail is fixedly installed in the center of the front surface of the movable plate 18.
[0020] A lifting cylinder 22 is fixedly installed on one side of the top of the base plate 23. A slider 21 is fixedly installed at the center of one side of the grinder 20. A slide block 19 is fixedly installed near the center of one side of the moving plate 18. One side of the slider 21 extends into the interior of the slide block 19 and slides in connection with the inner wall of the slide block 19. A piston rod is fixedly connected to the top output end of the lifting cylinder 22. The upper end of the piston rod is fixedly connected to the bottom of the grinder 20. The lifting cylinder 22 drives the grinder 20 to move vertically. The sliding cooperation between the slider 21 and the slide block 19 maintains the stability of the movement and realizes the adjustment of the grinding.
[0021] The mechanical parts to be processed are inserted into the clamping groove of the clamping sleeve 3, with both ends protruding outside the clamping sleeve 3. The clamping electric cylinder 4 is activated, pushing the clamping plate 5 upward through the piston rod, which cooperates with the top rubber plate 6 to achieve elastic clamping and avoid damaging the surface of the workpiece. When the other end of the workpiece needs to be ground, the motor 26 drives the drive gear 10 to rotate, which drives the meshing driven gear 11 and the rotating rod 25 to rotate synchronously. The rotating disk 13, which is fixedly connected to the lower end of the rotating rod 25, rotates horizontally in the annular seat 12. The annular sliding plate 14 on its outer wall slides along the annular groove 15 to restrain radial sway and ensure smooth rotation. The rotating disk 13 drives the clamping sleeve 3 to rotate synchronously through the first connecting block, adjusting the end face to be processed to the direction of the grinding machine 20. The handrail on the front surface of the moving plate 18 is pushed and moved horizontally along the guide rod 16 through the guide sleeve 17 to adjust the lateral position of the grinding machine 20. The lifting cylinder 22 drives the piston rod to extend and retract, driving the grinding machine 20 to rise and fall vertically along the slide block 19 through the slider 21, accurately adjusting the grinding height to match the workpiece specifications. The grinding machine 20 is started to grind the end face of the positioned workpiece. After processing, the clamping electric cylinder 4 releases the clamping force and takes out the workpiece.
[0022] In summary, this mechanical parts grinding and positioning assembly, through the design of the driving gear 10, driven gear 11, annular seat 12, rotating disk 13, annular slide plate 14, annular groove 15, rotating rod 25, and motor 26, allows the motor 26 to drive the driving gear 10 to rotate, which in turn drives the meshing driven gear 11 and rotating rod 25 to rotate synchronously. This causes the rotating disk 13, which is fixed to the lower end of the rotating rod 25, to rotate horizontally within the annular seat 12. The annular slide plate 14 on the outer wall of the rotating disk 13 slides inside the annular groove 15, forming a radial limiting structure that effectively suppresses the wobble phenomenon during rotation and ensures the stability of rotation positioning. The clamping sleeve 3 is fixed to the rotating disk 13 through the top connecting block, achieving synchronous rotation. This allows the clamped part to be adjusted to the working position of the grinding machine 20 without disassembly. This structural combination simplifies multi-faceted processing operations, enabling grinding of both ends of mechanical parts in a single clamping, reducing repeated positioning errors, and significantly improving processing efficiency and positioning accuracy.
