Abstract
Description
Technical Field
[0001] This application relates to the technical field of spherical grinding machines, and more particularly to a spherical grinding machine with a moving structure. Background Technology
[0002] Spherical grinding machines are key equipment in the field of precision machining. After a single clamping, the sphere can automatically and continuously complete surface grinding to generate an ideal spherical trajectory. With the rapid development of industrial technology, especially in the valve industry, various valves require precision-machined components. Among them, the hard-seal sphere, as an important component of the ball valve, needs to be ground by a spherical grinding machine to obtain the ideal spherical shape. Since the intense friction between the sphere and the grinding wheel generates high temperatures, water spraying is required for cooling during the grinding process. At the same time, water spraying can wash away the metal chips generated during grinding, preventing the metal chips from accumulating in the grinding area and affecting the grinding quality and grinding wheel life.
[0003] In related technologies, a spherical grinding machine includes a grinding wheel, a first ejector rod assembly, a second ejector rod assembly, and a base. The grinding wheel, the first ejector rod assembly, and the second ejector rod assembly are all mounted on the base. The grinding wheel is used for grinding spheres, and the first and second ejector rod assemblies are used to fix the spheres. The first and second ejector rod assemblies are located in relative positions on the same plane. A power assembly is provided on the base to drive the first ejector rod assembly to rotate.
[0004] Because the spheres to be ground are of different sizes, but the distance between the first push rod component and the second push rod component is fixed, the size of the spheres that can be adapted is greatly limited. Therefore, the spherical grinding machine cannot be used for spheres that are too large or too small, and can only grind spheres of a single size. Utility Model Content
[0005] To overcome the limitations of spherical grinding machines in adapting to the size of spheres, this application provides a spherical grinding machine with a moving structure.
[0006] This application provides a spherical grinding machine with a moving structure, which adopts the following technical solution:
[0007] A spherical grinding machine with a movable structure includes a grinding wheel, a first ejector rod component, a second ejector rod component, and a base. The grinding wheel, the first ejector rod component, and the second ejector rod component are all mounted on the base. A power assembly is provided on the base to drive the first ejector rod component to rotate. A water spray component is provided on the base to rinse and cool the sphere. A drive assembly is provided on the base to drive the second ejector rod component to move. Two parallel flat plates are slidably connected on the base. The two flat plates are respectively fixed to the first ejector rod component and the second ejector rod component, and the two flat plates are used to block water flow towards the drive assembly.
[0008] By adopting the above technical solution, the drive assembly can drive the second push rod component to move, thereby changing the distance between the first and second push rod components. This allows for the fixing of spheres of different sizes, enabling the spherical grinding machine to accommodate spheres of more sizes. Furthermore, the base is equipped with a water spray component for rinsing and cooling the spheres. Two parallel and staggered flat plates are slidably connected to the base, and these two plates are respectively fixed to the first and second push rod components. This allows the flat plates to block water flow towards the drive assembly, reducing the possibility of water ingress into the drive assembly, further preventing drive assembly malfunctions, and extending the service life of the drive assembly.
[0009] Optionally, multiple plates are slidably connected between the two plates, and the multiple plates are arranged in parallel and staggered arrangement. Each of the multiple plates has a moving groove and a connecting strip, which is used to slide within the moving groove of adjacent plates. When the connecting strip abuts against the groove wall of the moving groove near the first push rod component, the multiple plates overlap. When the connecting strip abuts against the groove wall of the moving groove near the second push rod component, the multiple plates unfold.
[0010] By adopting the above technical solution, multiple parallel and staggered plates are slidably connected between two plates, which expands the adjustable distance range between the first push rod component and the second push rod component. Since the plates are of standardized size, different models of spherical grinding machines can achieve the corresponding distance by using different numbers of plates. Manufacturers do not need to customize and produce plates of different sizes, which enables manufacturers to reduce production costs and improve production efficiency.
[0011] Optionally, a filter screen is detachably connected between the first push rod component and the second push rod component. The filter screen has locking strips on both sides. The first push rod component has a first locking groove for inserting the locking strips, and the second push rod component has a second locking groove for inserting the locking strips. Both the first and second locking grooves extend in the direction close to the mold. When the water spraying component sprays water, the filter screen is located between the sphere and the plate. The base is provided with a drainage pipe for diverting wastewater to the water spraying component for recycling.
[0012] By adopting the above technical solution, when the water spraying component sprays water, the filter screen is located between the ball and the plate, and a drainage pipe for draining sewage is provided on the base. This allows the filter screen to filter the metal shavings washed down from the ball and reduces the possibility of metal shavings clogging the drainage pipe. Users do not need to frequently clean the metal shavings that accumulate on the bottom surface of the base and in the drainage pipe.
[0013] Optionally, both the first and second card slots have grooves, and the card strips can be inserted into the grooves; when the card strips are both inserted into the grooves, the filter screen is fixed in the first and second card slots.
[0014] By adopting the above technical solution, grooves for inserting the clips are provided on both the first and second slots, which allows the filter screen to be better fixed in the first and second slots, reducing the displacement of the filter screen due to water flow scouring, enabling the filter screen to filter metal shavings and reducing the possibility of metal shavings clogging the drain pipe.
[0015] Optionally, the filter screen can be detachably connected to a fixing mesh on both the side closest to and furthest from the mold. When the filter screen is bent, both fixing meshes block the area from the lowest point to the highest point of the filter screen.
[0016] By adopting the above technical solution, when the filter screen is bent, the lowest point on both sides of the filter screen to the highest point of the filter screen is blocked by the fixed net, so that the metal shavings on the filter screen will not be washed off and fall onto the plate. This makes it easier to clean and handle the metal shavings, and keeps the plate clean, reducing the possibility of metal shavings clogging the movement path of the plate.
[0017] Optionally, the plate is provided with a baffle, which abuts against an adjacent plate and is used to prevent water from flowing through the gap between the plates.
[0018] By adopting the above technical solution, the baffle abuts against the adjacent plate. The baffle is used to block water from flowing through the gap between the plates, reducing the possibility of water residue accumulating at the bottom of the plate. Moreover, the water will be splashed onto other parts during the movement of the plate, thereby preventing the plate or other parts from rusting and extending the service life of the equipment.
[0019] Optionally, a card block is slidably connected in the first card slot, and a receiving groove is provided on the card block. A cleaning brush is rotatably connected to the receiving groove. The cleaning brush can extend towards the second push rod component and can abut against the second push rod component. When the cleaning brush is in the retracted state, the entire cleaning brush is located in the receiving groove. When the filter screen is in the taut state, the cleaning brush abuts against the filter screen.
[0020] By adopting the above technical solution, when the filter screen is in a taut state, the cleaning brush can extend towards the second push rod component and abut against the second push rod component. The cleaning brush abuts against the filter screen, allowing the cleaning brush to cover the length range between the first push rod component and the second push rod component. Since both the first and second slots penetrate the first push rod component in a direction away from the abrasive, the cleaning brush can move in a direction away from the abrasive, thereby thoroughly cleaning the filter screen. Users do not need to carry additional cleaning tools, providing convenience for users to handle metal shavings on the filter screen.
[0021] Optionally, the first slot is provided with a protrusion, which is elastic and can pass through the protrusion when the card block is located on the side of the protrusion closer to the mold direction.
[0022] By adopting the above technical solution, the card block is located on the side of the protrusion closer to the mold, so that the card block can be fixed on the side of the first card slot closer to the mold. The protrusion can prevent the card block from moving away from the mold, thus making it easier for the user to find the position of the cleaning brush.
[0023] Optionally, a fixing strip is provided in the second slot, and a through hole is provided in the second slot, through which the fixing strip passes. A limiting block is provided at one end of the cleaning brush near the second top rod component. The limiting block can pass through the through hole and be inserted into the second slot. When the limiting block moves in the second slot, the fixing strip is located on the movement path of the limiting block as it leaves the second slot.
[0024] By adopting the above technical solution, the limiting block can be inserted into the second slot through the through hole. The user can move the limiting block in the second slot. The fixing strip is located on the movement path of the limiting block to leave the second slot, so that the limiting block can move in the second slot without leaving the second slot, thereby preventing the cleaning brush from returning to the retracted state. This allows the user to clean the filter screen by pulling the cleaning brush away from the mold with one hand.
[0025] In summary, this application includes at least one of the following beneficial technical effects:
[0026] 1. The drive assembly can drive the second push rod component to move, allowing the distance between the first and second push rod components to change, thereby fixing balls of different sizes and enabling the spherical grinding machine to accommodate balls of more sizes. A water spray component for rinsing and cooling the balls is provided on the base. Two parallel and staggered flat plates are slidably connected to the base, and the two plates are respectively fixed to the first and second push rod components. This allows the flat plates to block water flow towards the drive assembly, reducing the possibility of water entering the drive assembly, further preventing drive assembly failure, and extending the service life of the drive assembly.
[0027] 2. When the water spraying component sprays water, the filter screen is located between the ball and the plate, and a drainage pipe for draining wastewater is provided on the base. This allows the filter screen to filter the metal shavings washed off the ball and reduces the possibility of metal shavings clogging the drainage pipe. Users do not need to frequently clean the metal shavings that accumulate on the bottom surface of the base and in the drainage pipe. Attached Figure Description
