Abstract
Description
Technical Field
[0001] The utility model relates to a grinding device, more specifically, it relates to a sphere grinding device. Background Art
[0002] A ball valve is a valve in which the valve stem drives the opening and closing part (ball) to rotate around the axis of the ball valve. The ball is the main core component that controls the opening and closing of the ball valve. In order to make the ball valve have good sealing when closed, the ball needs to be processed with high precision. Since the ball will rub against the valve seat or other sealing parts when rotating, it needs to be polished after the ball is formed.
[0003] The existing processing methods are roughly divided into two types: 1. Manual processing method, which uses sandpaper for manual polishing, but it is inefficient; 2. Using an automatic grinder to grind the surface of the sphere. This operation method requires the sphere to be moved to the platform of the grinder. If the sphere is too large, it is easy to cause the sphere to collide during the transportation process, and the sphere needs to be moved vertically multiple times, which is very time-consuming and labor-intensive. Utility Model Content
[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a ball grinding device, which can facilitate the transportation and grinding operations of the ball.
[0005] To achieve the above object, the utility model provides the following technical solutions: a ball grinding device, comprising a mounting seat and a movable seat, wherein the movable seat is detachably mounted on one side of the mounting seat, and a lifting baffle, a fixing mechanism, a grinding mechanism and a guide plate are arranged on the mounting seat, wherein the guide plate and the grinding mechanism are respectively arranged on the front and rear sides of the lifting baffle;
[0006] The fixing mechanism is provided with two groups, and is respectively provided on the left and right sides of the lifting baffle;
[0007] The movable seat is provided with a placement cavity, a feed port and a discharge port, the feed port and the discharge port are both provided with blocking plates, the placement cavity is provided with an adjustment plate and an adjustment motor for driving the adjustment plate to rotate, the adjustment plate is provided in a U-shaped structure, and a buffer structure is provided on the adjustment plate.
[0008] In summary, the utility model has the following beneficial effects: the mounting seat is placed on a designated work station, the ball can be driven for transportation through the movable seat, and the ball can be conveniently moved from the placement cavity to the mounting seat through the cooperation between the movable seat and the mounting seat.
[0009] The operating steps are: control the adjustment motor to tilt the adjustment plate toward the feed port, then open the blocking plate to place the ball into the placement cavity. At this time, since the adjustment plate is in an inclined state, the ball rests on the inner wall close to the feed port under the action of its own gravity. Then the operator pushes the moving seat to move. At this time, the ball can be relatively stably located in the cavity without collision or displacement.
[0010] When it moves to the fixed seat position, the discharge port is opened to align it with the guide plate. At this time, the adjusting motor is controlled to tilt the adjusting plate toward the discharge port, so that the ball gradually rolls outward, and under the action of the buffer structure, the rolling speed is slowed down to avoid collision. In the rolling process, the operator can assist in deceleration and correction to ensure that the ball is located in the position of the lifting baffle.
[0011] The operator then properly adjusts the angle and position of the sphere, starts the fixing mechanism to fix the two ends of the sphere, and finally grinds the surface of the sphere through the grinding mechanism.
[0012] Therefore, the grinding device can facilitate the transportation and grinding operations on the sphere. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.
[0020] Reference Figure 1 As shown, in order to achieve the above purpose, the utility model provides the following technical solutions: a ball grinding device, comprising a mounting seat 1 and a movable seat 2, the movable seat 2 is detachably mounted on one side of the mounting seat 1, and a lifting baffle 3, a fixing mechanism 4, a grinding mechanism 5 and a guide plate 6 are arranged on the mounting seat 1, and the guide plate 6 and the grinding mechanism 5 are respectively arranged on the front and rear sides of the lifting baffle 3;
[0021] The fixing mechanism 4 is provided with two groups, and is respectively arranged on the left and right sides of the lifting baffle 3;
[0022] A placement cavity 21, a feed port 22 and a discharge port 23 are provided in the movable seat 2. Blocking plates 24 are provided at the feed port 22 and the discharge port 23. An adjustment plate 25 and an adjustment motor 26 for driving the adjustment plate 25 to rotate are provided in the placement cavity 21. The adjustment plate 25 is provided in a U-shaped structure, and a buffer structure 27 is provided on the adjustment plate 25.
[0023] According to the design of the utility model, the mounting seat 1 is placed on a designated work station, and the ball can be transported by the moving seat 2. Moreover, the moving seat 2 and the mounting seat 1 cooperate to conveniently move the ball from the placement cavity 21 to the mounting seat 1. Compared with the existing transport vehicle, the moving seat can be conveniently adapted to the mounting seat, thereby improving the convenience of transportation.
[0024] The specific operating steps are: control the adjustment motor 26 to make the adjustment plate 25 tilt toward the feed port 22, then open the blocking plate 24 to place the ball into the placement cavity 21, at this time, since the adjustment plate 25 is in an inclined state, the ball rests on the inner wall on the side close to the feed port 22 under the action of its own gravity, and then the operator pushes the moving seat 2 to move, at this time the ball can be relatively stably located in the cavity, and no displacement or collision will occur.
[0025] When the movable seat 2 moves to the fixed seat position, the discharge port 23 is opened to align it with the guide plate 6. At this time, the adjusting motor 26 is controlled to tilt the adjusting plate 25 toward the discharge port 23, so that the ball gradually rolls outward, and under the action of the buffer structure 27, the rolling speed is slowed down to avoid collision of the ball. In the rolling process, the operator can assist in deceleration and correction to ensure that the ball is located at the position of the lifting baffle 3.
[0026] like Figure 4 As shown, the height of the feed port will be higher than the height setting of the discharge port.
[0027] The operator then appropriately adjusts the angle and position of the sphere, and then starts the fixing mechanism 4 to fix the two ends of the sphere, and finally the grinding mechanism 5 grinds the surface of the sphere.
[0028] Therefore, the grinding device can conveniently carry out the transport and grinding operations on the sphere.
[0029] The buffer structure 27 includes a plurality of rubber parts, which are arranged equidistantly along the length direction of the adjustment plate 25. Figure 5 As shown, the design of the rubber part can provide appropriate resistance to the two ends of the sphere during the downward movement of the sphere, thereby slowing down the movement speed of the sphere.
[0030] The lower end of the moving base 2 is provided with a moving wheel 28. Figure 1 As shown, the design of the structure enables the movable seat 2 to be easily moved.
[0031] Connecting buckles 29 are provided on both the left and right sides of the movable seat 2 , and connecting blocks 11 are provided on both the left and right sides of the mounting seat 1 .
[0032] like Figure 1 As shown, the design of this structure improves the stability of the connection between the moving seat 2 and the mounting seat 1 when the moving seat 2 and the mounting seat 1 are in contact with each other, through the connection buckle 29 which is buckled onto the connection block 11, thereby ensuring that the moving seat 2 and the mounting seat 1 will not separate during the transportation of the sphere.
[0033] The guide plate 6 is provided with an inclined guide slope 61, and the side of the guide plate 6 away from the grinding mechanism 5 is higher than the side close to the grinding mechanism 5. With this structural design, when the ball moves out of the discharge port 23, it can move along the guide slope 61 to the front of the lifting baffle 3.
[0034] The lifting baffle plate 3 is arranged in a U-shaped structure, and an elastic pad is arranged on the side of the lifting baffle plate 3 facing the guide plate 6; the design of the elastic pad can play a role in buffering and protecting the ball.
[0035] A lifting slot 12 is provided on the mounting seat 1 , and a lifting member for driving the lifting baffle 3 to move is provided inside the mounting seat 1 .
[0036] The lifting component can adopt a motor lifting rod and a cylinder, and the lifting component is used to control the up and down movement of the lifting baffle 3. When the sphere is placed on the mounting seat 1, the lifting baffle 3 needs to be raised. When the sphere is fixed by the fixing mechanism 4, the lifting baffle 3 needs to be lowered.
[0037] When the ball is moved into position, the lifting baffle is lowered by the lifting member so that the ball is completely exposed to the grinding mechanism of the fixing mechanism, and then the position of the ball is adjusted so that the two ends of the ball face the fixing mechanisms on both sides.
[0038] The grinding mechanism includes a grinding base 51 , a grinding motor 52 , a grinding disc 53 and a grinding piece 54 . The grinding motor 52 is mounted on the grinding base 51 , the grinding disc 53 is mounted on the output end of the grinding motor 52 , and a plurality of groups of grinding pieces 54 are provided.
[0039] like Figure 2 and Figure 3 As shown, the design of the grinding mechanism starts the grinding motor 52 to make the grinding disc 53 move in a circumferential direction, thereby driving the grinding pieces 54 and the spheres at different positions to perform grinding operations.
[0040] The position design of the grinding piece 54 can be as follows: the grinding piece 54 gradually approaches the center of the grinding disk 53, and there is a staggered arrangement between two adjacent grinding pieces 54, and can also be arranged along the diameter direction of the grinding disk. Different grinding pieces have different lengths and can perform grinding operations on arc-shaped spherical surfaces.
[0041] The polishing base 51 includes a fixed base 511 , a movable base 512 and a driving member 513 . The movable base 512 is movably connected to the fixed base 511 . The driving member 513 is used to drive the movable base 512 to move away from or close to the lifting baffle 3 .
[0042] The design of this structure can control the grinding piece 54 to be close to or away from the lifting baffle 3, so that when the ball reaches the specified position, the grinding piece 54 is away from the lifting baffle 3, and when the ball reaches the specified position, the grinding piece 54 is controlled to fully abut against the ball.
[0043] The fixing mechanism 4 includes a fixing base 41 , a fixing plate 42 and a driving cylinder 43 . The driving cylinder 43 is mounted on the fixing base 41 . The fixing plate 42 is mounted on the output end of the driving cylinder 43 . An arc-shaped fixing surface is provided on the fixing plate 42 .
[0044] The design of this structure enables the fixing plate 42 to abut against the end of the sphere through the driving cylinder 43, and fully abuts against the sphere through the arc-shaped fixing surface, thereby improving the fixing effect.
[0045] When the angle of the sphere needs to be adjusted, it can be divided into manual and automatic methods. The manual method is: the fixed plate is separated from the sphere by driving the cylinder, the operator checks and determines the surface to be polished, and then turns the surface to be polished toward the polishing mechanism, and then re-fixes it through the fixing mechanism.
[0046] Furthermore, the automatic method is as follows: a motor and a rotating disk are arranged on the fixed base 41, and a driving cylinder 43 is arranged on the rotating disk. The motor can drive the driving cylinder and the fixed disk to rotate, so that the ball also rotates, achieving a comprehensive grinding effect.
[0047] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
