Description

Technical Field

[0001] The utility model belongs to the technical field of roller processing and clamping, in particular to a clamping device for roller grinding processing. Background Art

[0002] Rollers are cylindrical, rotating objects in machinery. Power sources, such as motors, are often used to drive rollers, which in turn drive other materials forward, or to generate pressure to process materials. Rollers need to be polished after cutting. Existing roller polishing clamping devices are inconvenient for securing rollers of different sizes, resulting in a narrow range of applications. Furthermore, roller fixation is not ideal, and during the polishing process, the rollers are prone to shaking, affecting the processing quality.

[0003] Existing roller clamping devices can generally only clamp rollers of one size. As a result, when clamping rollers of different sizes, the roller clamping is easily unstable and the roller moves. Therefore, it is necessary to improve it. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the utility model provides a clamping device for roller grinding processing, which can solve the problem of better clamping rollers of different sizes.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clamping device for roller grinding processing, comprising a top plate, one side of the top plate is rotatably connected to a grab clamp, one side of the top of the top plate is fixedly connected to a half-moon plate, the middle of the half-moon plate is rotatably connected to a cylinder, the upper surface of the top plate is fixedly connected to a hollow box body, the middle of the top of the top plate is fixedly connected to a movable plate, the bottom of the movable plate is movably connected to a push rod, the back side of the grab clamp is slidably connected to a stop block, the front side of the stop block is fixedly connected to a limiting rod, the top of the arc-shaped stop block is slidably connected to a slider, the middle of the slider is fixedly connected to a pulling rod, the front side of the pulling rod is fixedly connected to a connecting rod, one end of the connecting rod is fixedly connected to the arc connecting plate, and the bottom of the back side of the grab clamp is fixedly connected to a heart-shaped auxiliary rod.

[0007] Preferably, a strip block is fixedly connected to the bottom of the cylinder, the strip block is fitted with a half-moon block, and the half-moon block is rotatably connected to the strip block.

[0008] Preferably, a connecting cylinder is fixedly connected to the top of the back side of the gripping clamp, and a circular block is fixedly connected to one end of the push rod, and a hole formed in the circular block matches the cylinder.

[0009] Preferably, the arc-shaped connecting plate is fixedly connected to the connecting cylinder, and the groove provided on the bottom of the sliding block slides in contact with the top of the stop block.

[0010] Preferably, a heart-shaped auxiliary rod is fixedly connected to the bottom of the back side of the gripping clamp.

[0011] Preferably, the blocking block is arc-shaped, and a sliding groove matching the limiting rod is provided on the front of the clamp.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The utility model achieves the purpose of better fixing rollers of different sizes by arranging the clamp, cylinder, push rod and stop block.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 4 As shown, the utility model provides a clamping device for roller grinding processing, including a top plate 1, one side of the top plate 1 is rotatably connected to a gripper 2, one side of the top of the top plate 1 is fixedly connected to a half-moon plate 4, the middle part of the half-moon plate 4 is rotatably connected to a cylinder 3, the upper surface of the top plate 1 is fixedly connected to a hollow box body 5, the middle part of the top of the top plate 1 is fixedly connected to a movable plate 7, the bottom of the movable plate 7 is movably connected to a push rod 6, the back of the gripper 2 is slidably connected to a stop block 8, the front of the stop block 8 is fixedly connected to a limiting rod 9, the top of the stop block 8 is slidably connected to a slider 10, the middle part of the slider 10 is fixedly connected to a pull rod 11, the front of the pull rod 11 is fixedly connected to a connecting rod 12, one end of the connecting rod 12 is fixedly connected to an arc-shaped connecting plate 14, and the bottom of the back of the gripper 2 is fixedly connected to a heart-shaped auxiliary rod 13.

[0021] The cylinder 3 is used to clamp the roller 2. First, the cylinder 3 is in an open state when it is not operating. The blocking block 8 on the back of the clamp 2 moves to both sides through the slider 10, and then is pulled upward by the limit rod 9. When the cylinder 3 is pushed forward, the push rod 6 on the movable plate 7 also pushes the connecting cylinder 16 forward through the circular block 15, so that the clamp 2 clamps the roller downward. The hollow box body 5 on the upper surface of the top plate 1 can protect the movable plate 7 and the push rod 6. After the clamp 2 is clamped, the blocking block 8 on the back also moves to the middle through the slider 10, and then fits the surface of the roller downward with the limit rod 9. In this way, rollers of different sizes can be clamped and they can also be better polished to avoid the upward displacement of some too small rollers after clamping and polishing.

[0022] like Figure 1 and Figure 2 As shown, the top plate 1 and the gripper 2 are rotatably connected, and a matching movable connecting rod is installed at the connection. The bottom of the cylinder 3 is fixedly connected with a strip block, which fits with the half-moon block 4, and the half-moon block 4 is rotatably connected to the strip block.

[0023] The above solution is adopted: through the top plate 1 and the clamp 2, when the cylinder 3 is in operation, the clamp 2 can be rotated through the connected movable connecting rod to open and clamp. The strip block and the half-moon block 4 at the bottom of the cylinder 3 fit together so that when the cylinder 3 is in operation, the bottom will move downward, which can enable the cylinder 3 to operate better and avoid the cylinder 3 being unable to operate due to being fixed. The inner side of the clamp 2 is in an arc shape, in order to better fit the surface of the roller and clamp it for easy grinding.

[0024] like Figure 1 and Figure 3As shown, the arc-shaped connecting plate 14 is fixedly connected to the connecting cylinder 16, the groove opened at the bottom of the slider 10 slides in contact with the top of the blocking block 8, and the bottom of the back of the clamp 2 is fixedly connected to a heart-shaped auxiliary rod 13.

[0025] The above scheme is adopted: through the arc-shaped connecting plate 14, when the cylinder 3 drives the gripper 2, it can also drive the resisting block 8 at the same time to avoid the phenomenon of asynchrony. Secondly, the arc-shaped connecting plate 14 is fixedly connected to the connecting cylinder 16 to avoid the phenomenon of rotation during upward operation, which will cause the resisting block 8 to be unstable. Secondly, the slider 10 can drive the connecting rods 12 on both sides to gather to the sides or to the middle, so that the subsequent resisting blocks 8 can fit and resist rollers of different sizes, avoiding the fixed connecting rod 12 from being unable to adjust according to the size of the roller. The heart-shaped auxiliary rod 13 on the back of the gripper 2 can support and stabilize the entire large gripper 2 device, avoiding the connection of the gripper 2 from being not firm enough.

[0026] like Figure 1 As shown, the top of the back of the gripper 2 is fixedly connected to a connecting cylinder 16, one end of the push rod 6 is fixedly connected to a circular block 15, the hole opened in the circular block 15 matches the connecting cylinder 16, the shape of the blocking block 8 is arc-shaped, and the front of the gripper 2 is provided with a sliding groove matching the limit rod 9.

[0027] The above solution is adopted: by connecting the cylinder 16, the entire clamp 2 can be connected and fixed by the cylinder 16 to prevent the clamp 2 from being unstable in connection, resulting in looseness when clamping the roller later, causing safety problems. Secondly, the circular block 15 at one end of the push rod 6 matches the size of the cylinder 16 to ensure better pulling of the entire clamp 2. The mismatched circular block 15 will produce automatic offset. The shape of the resisting fast 8 is arc-shaped, so that it can fit better on the surface of the roller, ensuring that rollers of different sizes will not move upward during clamping and grinding. Secondly, the slide groove opened on the front of the clamp 2 can enable the limit rod 9 on the resisting fast 8 to slide, and can also ensure that the resisting fast 8 cannot be manually moved without the cylinder 3 being opened, so as to avoid problems during subsequent use.

[0028] The working principle and use process of this utility model:

[0029] When the roller is needed to be clamped, the cylinder 3 is started and pushed forward. When the cylinder 3 is pushed, the strip block and the half-moon plate 4 at the bottom of the cylinder 3 fit together so that when the cylinder 3 is operating, the bottom will play a downward movement, which can make the cylinder 3 operate better. At the same time, the push rod 6 on the movable plate 7 also pushes the connecting cylinder 16 forward through the circular block 15, so that the clamp 2 clamps the roller downward. After the clamp 2 is clamped, the back stop block 8 also moves to the middle through the slider 10, and then fits the surface of the roller downward with the limit rod 9. In this way, rollers of different sizes can be clamped and polished better to avoid the phenomenon that some rollers that are too small will shift upward after clamping and polishing.
