Technical Field
[0001] The utility model belongs to the technical field of machine tools, in particular to a machine tool for processing a three-dimensional eccentric butterfly valve. Background Art
[0002] The processing machine tool of the eccentric butterfly valve is a device used to produce and process the eccentric butterfly valve. Generally, the processing machine tool of the eccentric butterfly valve includes the following process steps: Material preparation: Select suitable materials for processing, usually metal materials such as cast iron, stainless steel, etc. Cutting: Use a cutting machine to cut the material into the required size. Rough processing: Use milling machines, lathes and other equipment to rough process the material so that its shape meets the design requirements. Drilling: Use a drilling machine or drill to drill the hole of the butterfly valve. Processing butterfly valve seat: Use lathes and other equipment to process the butterfly valve seat to ensure the sealing performance. Assembly: Assemble the various components together, including the valve body, butterfly plate, valve stem, etc. Inspection: Carry out strict inspection to ensure that the quality of the butterfly valve meets the standard requirements. When the worker is rough processing the eccentric butterfly valve, by placing the raw material on the milling machine, the chip cutter cuts the raw material. Therefore, it can be seen that the existing machine tools basically meet people's practical needs, but there are still the following problems.
[0003] However, since the material of the eccentric butterfly valve is generally cast iron or stainless steel, and it is a whole piece of iron, the raw material may be heavy. In order to facilitate the transportation of the raw material and the roughly processed parts, the operator may use lifting equipment to transport the raw material or the roughly processed parts. When the operator places the raw material on the loading platform, due to the heavy volume of the raw material, the operator may not be able to fine-tune the position of the raw material placed on the loading platform, which may cause inconvenience to the operator when processing the raw material. For this reason, we propose a three-dimensional eccentric butterfly valve processing machine tool. Utility Model Content
[0004] The utility model provides a three-dimensional eccentric butterfly valve processing machine tool, which drives a rolling ball installed on a loading platform through a fixed plate. When a raw material is placed on the loading platform, the raw material and the rolling ball fit each other. When an operator pushes the raw material, the raw material drives the rolling ball to rotate in the ball groove, thereby reducing the friction between the raw material and the loading platform and improving the convenience of the operator in adjusting the position of the raw material.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a three-dimensional eccentric butterfly valve processing machine tool, including a machine tool body and a loading platform, the loading platform is installed on the surface of the machine tool body, a fixed plate is symmetrically inserted in the middle of the loading platform, and a plurality of groups of ball grooves are opened in the middle of the fixed plates, and the ball grooves are embedded with rolling balls, and a rotating rod fixed on the inner wall of the loading platform passes through the middle of the fixed plates.
[0006] Furthermore, fixed blocks are symmetrically fixed to the two side ends of the machine tool body, and spring grooves are symmetrically opened inside the fixed blocks. Push rods are embedded in the spring grooves, and springs are wound on the surfaces of the push rods. The two side ends of the springs are respectively abutted between the push rod surface and the inner wall of the spring grooves. Clamps are fixed to the ends of the push rods, and a limit block inserted in the middle of the fixed plate is fixed on one side where the clamp and the surface of the fixed plate are in contact with each other.
[0007] Furthermore, the limiting blocks are all configured to be in a round cake shape, and the round cake shape of the limiting blocks matches the waist-shaped hole opened in the middle of the fixing plate.
[0008] Furthermore, the gap between the two groups of clamping plates matches the surface width of the fixing plate.
[0009] Furthermore, a handle is fixed at the end of the fixing plate, and the middle of the handle is set as an arc-shaped groove, and a plurality of groups of anti-slip points are fixed on the surface of the handle.
[0010] Furthermore, avoidance grooves are provided at both side ends of the loading platform, and a fixing plate is inserted into the middle of the avoidance grooves, and the rectangular notches provided in the avoidance grooves match the surface width of the fixing plate.
[0011] The beneficial effects of the utility model are:
[0012] 1. The processing machine tool of the three-dimensional eccentric butterfly valve is provided with a fixed plate, a ball groove and a rolling ball. After the operator inserts the fixed plate into the loading platform, several groups of rolling balls arranged in the middle of the fixed plate are mounted on the loading platform. Then, after the operator places the raw material on the loading platform, the raw material and the rolling ball fit each other. When the operator pushes the raw material, the raw material drives the rolling ball to rotate in the ball groove, thereby reducing the friction between the raw material and the loading platform and improving the convenience of the operator in adjusting the position of the raw material.
[0013] 2. The processing machine tool of the three-dimensional eccentric butterfly valve is provided with a clamping plate and a limit block. After the operator takes the fixed plate out of the loading platform, the two sets of clamping plates clamp the fixed plate, and the fixed limit blocks at the ends of the two sets of clamping plates are inserted into the waist-shaped holes opened in the middle of the fixed plate to fix the position of the fixed plate, so as to prevent the fixed plate from shaking randomly when the operator no longer uses the fixed plate, thereby improving the stability of the operator's use.

[0023] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.
[0024] Example:
[0025] See also Figure 1 - Figure 7A three-dimensional eccentric butterfly valve processing machine tool includes a machine tool body 1 and a stage 2. The stage 2 is installed on the surface of the machine tool body 1. A fixing plate 7 is symmetrically inserted in the middle of the stage 2, and a plurality of ball grooves 14 are opened in the middle of the fixing plate 7. The ball grooves 14 are embedded with rolling balls 6. The middle of the fixing plate 7 is penetrated by a rotating rod 5 welded on the inner wall of the stage 2. Avoidance grooves 8 are opened at both ends of the stage 2, and the fixing plate 7 is inserted in the middle of the avoidance grooves 8. The rectangular notch set in the avoidance grooves 8 matches the surface width of the fixing plate 7. When the operator needs to process the eccentric butterfly valve When the workpiece is placed on the loading platform 2, the operator first pulls the fixing plate 7 to make the waist-shaped hole in the middle of the fixing plate 7 rotate on the surface of the cylindrical rotating rod 5 to rotate the fixing plate 7. After the fixing plate 7 is rotated 90 degrees to make the fixing plate 7 and the loading platform 2 parallel to each other, the operator pushes the fixing plate 7 to make the waist-shaped hole in the middle of the fixing plate 7 slide on the surface of the rotating rod 5 to move the fixing plate 7 into the loading platform 2. When the fixing plate 7 moves into the loading platform 2, the operator places the workpiece on the loading platform 2. When the workpiece is placed on the loading platform 2, the surface of the workpiece fits with the surface of the rolling ball 6. After the workpiece and the surface of the ball 6 are in contact with each other, the operator pushes the workpiece to move, so that the workpiece drives the ball 6 to move. Since the ball 6 is set in a spherical shape, when the workpiece moves on the surface of the ball 6, the workpiece pushes the ball 6 to roll in the ball groove 14, thereby rolling the ball 6 on the surface of the workpiece, thereby reducing the friction between the workpiece and the stage 2 when the operator pushes the workpiece to move on the surface of the stage 2, which is convenient for the operator to adjust the position of the workpiece on the stage 2. When the position of the stage 2 is moved, the operator pulls the fixing plate 7, and the fixing plate 7 drives the ball 6 to move through the ball groove 14. The ball 6 moves, and the waist-shaped hole in the middle of the fixed plate 7 slides on the surface of the rotating rod 5 again, and the other end of the waist-shaped hole in the middle of the fixed plate 7 is moved to the surface of the rotating rod 5. Then the operator pushes the fixed plate 7, and the waist-shaped hole in the middle of the fixed plate 7 rotates on the surface of the rotating rod 5 again, and the fixed plate 7 is avoided through the avoidance groove 8, so that the fixed plate 7 and the worktable 2 are perpendicular to each other, and the fixed plate 7 is mounted on the lower end of the workpiece through the ball 6, which makes the workpiece unable to be stably placed on the worktable 2, thereby improving the operator's fine adjustment of the position of the workpiece on the worktable 2.
[0026] In other embodiments, fixed blocks 10 are symmetrically welded to the ends of both sides of the machine tool body 1, and spring grooves 11 are symmetrically opened inside the fixed blocks 10, push rods 12 are embedded in the spring grooves 11, and springs 4 are wound on the surfaces of the push rods 12, and the ends of the springs 4 are respectively abutted between the surfaces of the push rods 12 and the inner walls of the spring grooves 11, and clamps 9 are welded to the ends of the push rods 12, and the clamps 9 and the surfaces of the fixed plates 7 are in contact with each other. One side is welded with a limit block 13 inserted into the middle of the fixed plate 7, and the limit blocks 13 are all set to a round cake shape, and the round cake shape of the limit blocks 13 matches the waist-shaped hole opened in the middle of the fixed plate 7. When the operator does not use the fixed plate 7, the fixed plate 7 is taken out of the worktable 2, and the operator first pulls the clamps 9, and the clamps 9 drive the push rods 12 to slide in the spring grooves 11. When the push rods 12 move in the spring grooves 11 After sliding, the push rod 12 squeezes the spring 4, causing the spring 4 to undergo elastic deformation. After the spring 4 undergoes elastic deformation, the spring 4 avoids the push rod 12, causing the push rod 12 to move out of the spring groove 11, and the two groups of clamps 9 are moved away from the surface of the fixed block 10. The operator then places the fixed plate 7 between the two groups of clamps 9. The operator then releases the clamps 9. After the clamps 9 no longer squeeze the spring 4 through the push rod 12, the elastic deformation of the spring 4 is restored, and the spring 4 pushes the push rod 12 to move, causing the push rod 12 to drive the clamps 9 to move. The two groups of clamps 9 are clamped on the surface of the fixed plate 7, and the clamps 9 drive the limit block 13 to move, causing the limit block 13 to be inserted into the waist-shaped hole opened in the middle of the fixed plate 7, so that the operator can fix the two groups of fixed plates 7 to prevent the two groups of fixed plates 7 from shaking at will when the operator no longer uses the fixed plate 7.
[0027] In other embodiments, the gap between the two groups of splints 9 matches the surface width of the fixed plate 7. By matching the gap between the two groups of splints 9 and the surface width of the fixed plate 7, the two groups of splints 9 can clamp the fixed plate 7. When the two groups of splints 9 clamp the fixed plate 7, the opposite sides of the two groups of splints 9 fit against the surface of the fixed plate 7, thereby improving the stability of the two groups of splints 9 in clamping the fixed plate 7.
[0028] In other embodiments, a handle 3 is welded to the end of the fixed plate 7, and an arc-shaped groove is set in the middle of the handle 3. A plurality of anti-slip points 15 are hot-melt-bonded on the surface of the handle 3. When the operator pulls the fixed plate 7 to move, the operator first holds his hand on the surface of the handle 3. Since an arc-shaped groove is provided in the middle of the handle 3, the arc-shaped groove provided in the middle of the handle 3 is convenient for accommodating the operator's hand, thereby increasing the comfort of the operator's hand holding the surface of the handle 3. After the operator holds his hand on the surface of the handle 3, the plurality of anti-slip points 15 fixed on the surface of the handle 3 are convenient for increasing the contact area of the operator's hand on the surface of the handle 3, thereby improving the stability of the operator's hand holding the surface of the handle 3. After the operator holds his hand on the surface of the handle 3, the operator pulls the handle 3, and the handle 3 drives the fixed plate 7 to move, thereby facilitating the operator to pull the fixed plate 7 to move.
