Description

Technical Field

[0001] This utility model belongs to the field of casting processing technology, and in particular relates to a multi-station synchronous grinding device for cylindrical castings. Background Technology

[0002] Grinding is an indispensable step in the machining of castings, especially when manufacturing large cylindrical castings, where the quality and efficiency of grinding have a crucial impact on the entire production process.

[0003] Currently, most grinding equipment on the market is designed for small to medium-sized or relatively simple-shaped castings and generally adopts a single-station operation mode. This single-station or production line grinding method is acceptable for small castings, but for large castings, it is necessary to clamp and rotate the workpiece multiple times to complete the grinding of different positions. Once the workpiece reaches the target position, the operator needs to make manual adjustments or manual operations. This not only increases labor costs but also greatly extends the production cycle, resulting in low overall production efficiency.

[0004] Furthermore, when grinding large cylindrical castings, existing equipment often requires a large floor area to configure multiple single workstations or equipment, resulting in insufficient utilization of production line space and seriously affecting the utilization rate of production space.

[0005] Therefore, how to efficiently and uniformly complete the grinding of large-volume cylindrical castings has become a pressing problem to be solved in current technology. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0025] Example

[0026] like Figure 1 , Figure 3 As shown, the multi-station synchronous grinding device for cylindrical castings includes a base 10. A rotating support mechanism 20 and a positioning mechanism 40 are provided on the top of the base 10. A multi-station grinding mechanism 30 is mounted on the rotating support mechanism 20, and the positioning mechanism 40 is located directly below the multi-station grinding mechanism 30. Before grinding, the rotating support mechanism 20 is rotated to adjust the position of the multi-station grinding mechanism 30, so that the multi-station grinding mechanism 30 is offset from the positioning mechanism 40. Then, the large-volume cylindrical casting is vertically clamped and placed on the positioning mechanism 40, and its bottom end is fixed to the positioning mechanism 40. At this time, the upper half of the large-volume cylindrical casting is exposed. Then, the rotating support mechanism 20 is rotated to bring the multi-station grinding mechanism 30 and the exposed vertical cylindrical casting into contact.

[0027] The multi-station grinding mechanism 30 includes a drive assembly, a connecting assembly, and a grinding assembly. The grinding assembly includes a side grinding plate 37 and a top grinding plate 38 that are detachably mounted on the connecting assembly. The top of the side grinding plate 37 and the bottom of the top grinding plate 38 are flush. The side grinding plate 37 is arc-shaped and fits the side wall of the cylindrical casting. The drive assembly drives the side grinding plate 37 and the top grinding plate 38 to grind the side wall and one end of the casting simultaneously.

[0028] This utility model uses a drive assembly to drive the side grinding plate 37 and the top grinding plate 38, which can simultaneously grind the top and outer wall of the exposed vertical cylindrical casting. After grinding is completed, the direction of the cylindrical casting is reversed, and the outer wall of the other end and the remaining part can be ground, which greatly improves the overall grinding efficiency. Moreover, the equipment occupies a small area and makes fuller use of the production line space.

[0029] like Figure 1 As shown, the rotating support mechanism 20 includes a rotating base 21 fixedly connected to the top of the base 10. A vertical rod 22 is rotatably connected to the top of the rotating base 21, and a top plate 25 is fixedly connected to the top of the vertical rod 22. A pin block 23 is provided on the top of the rotating base 21, and a handle 24 is fixedly connected to the outer side wall of the vertical rod 22.

[0030] The working principle of the rotating support mechanism 20 driving the multi-station grinding mechanism 30 to rotate is as follows: before rotation, first pull out the pin 23, then hold the handle 24 to drive the vertical rod 22 to rotate on the rotating base 21, and after the rotation is finished, put the pin 23 back in.

[0031] like Figure 2 As shown, the positioning mechanism 40 includes a positioning cylinder 41 fixedly connected to the top of the base 10, and a clamping plate 42 is slidably connected to the inner side wall of the positioning cylinder 41; a second screw 43 is threadedly inserted into the side wall of the positioning cylinder 41, and one end of the second screw 43 extending into the inside of the positioning cylinder 41 is rotatably connected to the outer side of the clamping plate 42.

[0032] The working principle of the positioning mechanism 40 is as follows: when the bottom end of the vertical cylindrical casting is placed into the inner cavity of the positioning cylinder 41, the second screw 43 is rotated to drive the clamping plate 42 to move towards each other until the clamping plate 42 clamps and fixes the bottom end of the cylindrical casting.

[0033] like Figure 3 As shown, the drive assembly includes a motor 31 mounted on the top of the top plate 25, a rotating disk 32 rotatably connected to the bottom of the top plate 25, and the output shaft of the motor 31 passes through the top plate 25 and is fixed at the top center of the rotating disk 32.

[0034] The connecting assembly includes two symmetrically arranged hollow plates 33 fixedly connected to the bottom of the rotating disk 32. A sliding plate 34 is vertically slidably connected inside the hollow plate 33. A first screw 35 is threaded through the sliding plate 34, and the outer side of the side grinding plate 37 is rotatably connected to one end of the inner side of the first screw 35.

[0035] The connecting assembly also includes a connecting block 39, on both sides of which a connecting plate 310 is detachably and fixedly connected. The other end of the connecting plate 310 is fixed to the top outer side of the side grinding plate 37. The top grinding plate 38 is detachably and fixedly installed at the bottom of the connecting block 39.

[0036] The working principle of the multi-station grinding mechanism 30 is as follows: the multi-station grinding mechanism 30 is driven to rotate to the same axial position as the cylindrical casting by the rotating support mechanism 20, and then the first screw 35 is rotated to drive the two side grinding plates 37 to move towards each other until the inner side of the side grinding plate 37 is in contact with the outer wall of the cylindrical casting. In this embodiment, a guide rod is fixedly connected to the outer side of the connecting plate 36, and the other end of the guide rod moves through the sliding plate 34. Under the action of the guide rod, the stability of the horizontal movement of the side grinding plate 37 is ensured. In this embodiment, the side grinding plate 37 is detachably installed on the connecting plate 36, and the top grinding plate 38 is detachably installed on the connecting block 39. Therefore, when the side grinding plate 37 and the top grinding plate 38 are worn to a certain extent, they are easy to replace and install, making them more convenient to use.

[0037] like Figure 3 , Figure 4 As shown, the top grinding plate 38 is in the shape of a skateboard with both ends raised upwards; the bottom of the rotating disk 32 is provided with an elastic element 311, and the elastic element 311 is located above the connecting block 39; the elastic element 311 includes an upper cylinder 3111 fixedly connected to the bottom of the rotating disk 32, a lower cylinder 3112 vertically slidably connected to the inner wall of the upper cylinder 3111, and a spring 3113 fixedly connected between the top inner wall of the upper cylinder 3111 and the bottom inner wall of the lower cylinder 3112.

[0038] Under the elastic action of spring 3113, the bottom height of the top grinding plate 38 is slightly lower than the top height of the vertically fixed cylindrical casting. When the multi-station grinding mechanism 30 is rotated by the rotating support mechanism 20, the top grinding plate 38 first contacts the top of the cylindrical casting at both ends. Under the action of its upward-curving, plate-like ends, the top grinding plate 38 can be lifted up to a certain height until the bottom of the top grinding plate 38 contacts the top of the cylindrical casting. At this time, the spring 3113 is in a compressed state, ensuring that the bottom of the top grinding plate 38 can press down on the top of the cylindrical casting, thereby ensuring the grinding effect on the top of the cylindrical casting during subsequent rotation.

[0039] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
