[0019] The first embodiment of the present application is:

[0020] See also Figure 1-3 , Figure 1 This is a schematic diagram of the overall structure of an end grinding device for metal casting processing in the first embodiment of the utility model. Figure 2 is a schematic structural diagram of a support member of the first embodiment of the utility model, Figure 3 It is a schematic diagram of the connection between the rotating shaft and the clamping block of the first embodiment of the utility model.

[0021] The utility model provides an end grinding device for metal casting processing: comprising a base 101 and a grinding device, and also comprising a limiting device, wherein the limiting device comprises a support rod 102, a clamping seat 103, a rotating shaft 104, a clamping block 105 and a clamping drive assembly, wherein the clamping drive assembly comprises a wedge block 107, a connecting rod 108, a clamping cylinder 109 and a supporting member, wherein the supporting member comprises an inclined rod 111 and a supporting block 112. The above-mentioned scheme solves the problem that when the casting is fixed, the device fixes the side and end of the casting by the limiting devices on all sides, and when the end of the casting needs to be ground, the grinding device is not convenient to operate. It can be understood that the present scheme can also be used to solve the problem of grinding the end of the casting.

[0022] In this embodiment, the clamping drive assembly cooperates with the rotation of the clamping block 105 and the rotating shaft 104, so that the upper ends of the clamping blocks 105 on both sides are closed and the middle part of the casting on the clamping seat 103 is clamped, thereby achieving a fixing effect on the middle part of the casting, and making it easier for the grinding device to grind the end of the casting.

[0023] Among them, the support rod 102 is fixedly installed on the base 101, the clamping seat 103 is fixedly installed on the support rod 102, and through grooves 106 are provided on both sides of the clamping seat 103. The rotating shaft 104 is rotatably installed on the clamping seat 103 and is located in the through grooves 106. The clamping block 105 is fixedly installed on the rotating shaft 104 through the clamping drive assembly. The number of the support rods 102 is four groups, and they are welded at the four corners of the bottom of the clamping seat 103. The through grooves 106 are rectangular. The number of the rotating shafts 104 is two groups, and they are rotatably installed in the through grooves 106 on both sides through bearings. The number of the clamping blocks 105 is also two groups, and the two groups of rotating shafts 104 respectively pass through the two groups of clamping blocks 105. At the same time, the clamping blocks 105 are welded on the rotating shafts 104. The clamping blocks 105 are in an arc-shaped structure, and the openings of the clamping blocks 105 on both sides are arranged opposite to each other. The clamping drive assembly drives the bottom ends of the clamping blocks 105 on both sides to open outward, so that the upper ends of the clamping blocks 105 on both sides begin to close under the rotation cooperation of the rotating shaft 104, and clamp the middle part of the casting on the clamping seat 103, thereby achieving a fixing effect on the middle part of the casting, and then facilitating the grinding device to grind the end of the casting.

[0024] Secondly, the clamping cylinder 109 is installed on the base 101 through the supporting member. A movable groove 110 is provided on one side of the base 101. The output end of the clamping cylinder 109 passes through the movable groove 110. The connecting rod 108 is fixedly connected to the output end of the clamping cylinder 109. The wedge block 107 is fixedly installed on the connecting rod 108 and is close to the clamping block 105. The number of the connecting rods 108 is two groups, which are symmetrically distributed on both sides of the clamping cylinder 109. The two groups of One end of the connecting rod 108 is welded to both sides of the output end of the clamping cylinder 109. At the same time, the connecting rod 108 is a bent rod. The wedge block 107 is in an inverted triangle shape. The wedge block 107 is welded on the connecting rod 108. The clamping cylinder 109 drives the connecting rod 108 to move downward through the contraction of its own output shaft, and further drives the wedge block 107 to move downward. The wedge block 107 contacts with the lower end of the clamping block 105, so that the lower ends of the clamping blocks 105 on both sides are opened.

Then the clamping cylinder 109 is started, the output end of the clamping cylinder 109 contracts, and drives the connecting rods 108 on both sides to move downward, and the connecting rods 108 drive the wedge blocks 107 fixedly connected thereto to move downward. Since the wedge blocks 107 are located between the lower ends of the clamping blocks 105 on both sides, when the wedge blocks 107 contact the clamping blocks 105, the lower ends of the clamping blocks 105 on both sides open outward. Since the clamping blocks 105 are rotatably installed in the through grooves 106 through the rotating shaft 104, the upper ends of the clamping blocks 105 begin to close and clamp the middle part of the casting. At the same time, the end of the casting begins to be polished by the polishing device, thereby achieving a fixing effect on the middle part of the casting, which makes it easier for the polishing device to polish the end of the casting.
