[0034] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.
[0035] Reference Figure 1-5A mandrel sample end grinding device 100 is used for grinding the end face of a mandrel 101, comprising: a base 102, a fixing plate 103, a connecting plate 104, a guide post 105, a guide plate 106, a first spring 107, a grinding assembly for grinding the end face of the mandrel 101, and a fixing assembly for fixing the fixing plate 103. The grinding assembly is mounted on the guide plate 106, and the grinding assembly and the guide plate 106 are both located above the base 102. Two fixing assemblies are provided, which are respectively provided on both sides of the fixing plate 103. Two connecting plates 104 are provided, and the two connecting plates 104 are located on the circumference of the fixing plate 103.
[0036] The base 102 is provided with a first cavity 102a, and the fixed plate 103 is partially located in the first cavity 102a. The fixed plate 103 and the first cavity 102a have the same external structure. The base 102 is provided with a second cavity 102b, and the connecting plate 104 is located in the second cavity 102b. The second cavity 102b and the connecting plate 104 have the same external structure. The first cavity 102a is connected to the second cavity 102b. A plurality of guide pillars 105 are provided, preferably four, and the four guide pillars 105 are respectively arranged around the base 102. The guide pillar 105 is fixedly connected to the base 102. The fixed plate 103 is in contact with the base 102. The fixed plate 103 is provided with a placement hole 103a, and the placement hole 103a is provided with a plurality of holes, and the plurality of placement holes 103a are used to place the core rod 101. The connecting plate 104 is fixedly connected to the fixed plate 103. The guide pillar 105 is fixedly connected to the base 102.
[0037] The guide plate 106 is vertically slidably connected to the guide post 105. Specifically, the guide plate 106 is provided with a guide hole 106a, and the guide post 105 can move along the guide hole 106a. The first spring 107 is sleeved on the guide post 105, and the two ends are fixedly connected to the guide plate 106 and the base 102 respectively. The core rod 101 is placed in the placement hole 103a, and screws are provided on the circumference of the fixing plate 103; the core rod 101 is fixed to the fixing plate 103, and then the guide plate 106 is pushed. The movement of the guide plate 106 drives the grinding assembly to move, thereby grinding the end faces of multiple core rods 101.
[0038] The fixing assembly is used to fix the connecting plate 104 to the base 102, and includes: a first rotating shaft 108, an eccentric disk 109, and a push plate 110. The first rotating shaft 108 is rotatably connected to the base 102. The eccentric disk 109 is eccentrically arranged on the first rotating shaft 108 and fixedly connected to the first rotating shaft 108. The push plate 110 is fixedly connected to the eccentric disk 109. After the core rod 101 is ground, when the core rod 101 needs to be replaced, it is only necessary to push the push plate 110. The push plate 110 moves to drive the eccentric disk 109 to rotate along the circumference of the first rotating shaft 108, so that the connecting plate 104 is freed from the restriction of the eccentric disk 109, and the fixed plate 103 can be taken out, and the core rod 101 is replaced. The fixed plate 103 is inserted into the first cavity 102a, and the connecting plate 104 is inserted into the second cavity 102b. Then the push plate 110 is pushed. The push plate 110 moves to drive the eccentric disk 109 to rotate along the circumference of the first rotating shaft 108, so that the eccentric disk 109 fixes the connecting plate 104, and then the fixed plate 103 can be fixed, and installation and disassembly are more convenient.
[0039] The grinding assembly is used for grinding the end surface of the core rod 101, and includes a servo motor 112, a grinding wheel 113, a sandpaper 114, and a push rod 115. The servo motor 112 is fixedly connected to the guide plate 106. The guide plate 106 is provided with an air avoidance hole, and the air avoidance hole is for the driving shaft of the servo motor 112 to pass through, and a gap is set with the driving shaft. The grinding wheel 113 is fixedly connected to the driving shaft of the servo motor 112. The sandpaper 114 is bonded to the grinding wheel 113. The push rod 115 is fixedly connected to the guide plate 106. Multiple core rods 101 are placed in the placement hole 103a, and the servo motor 112 is driven. The servo motor 112 drives the grinding wheel 113 to rotate, and the rotation of the grinding wheel 113 drives the sandpaper 114 to rotate, so that the end surfaces of multiple core rods 101 are ground, so the processing efficiency is higher.
[0040] Working process: When in use, the core rod 101 is placed in the placement hole 103a, and screws are provided on the circumference of the fixing plate 103. The core rod 101 and the fixing plate 103 are fixed by screws, and the servo motor 112 is driven. The servo motor 112 drives the grinding wheel 113 to rotate, and the rotation of the grinding wheel 113 drives the sand skin 114 to rotate, and then pushes the push rod 115. The push rod 115 moves to drive the guide plate 106 to move, and the movement of the guide plate 106 drives the servo motor 112 to move, thereby driving the grinding wheel 113 to move, so that the sand skin 114 grinds the end face of the core rod 101, thereby grinding the end faces of multiple core rods 101, so the processing efficiency is higher. After grinding, release the push rod 115. Under the action of the first spring 107, the guide plate 106 will reset, thereby driving the grinding wheel 113 to reset, and then grind the other end of the core rod 101. It is only necessary to push the push plate 110. The push plate 110 moves and drives the eccentric disk 109 to rotate along the circumference of the first rotating shaft 108, so that the connecting plate 104 is freed from the restriction of the eccentric disk 109, and the fixing plate 103 can be taken out; insert the ground end of the core rod 101 into the placement hole 103a, and abut the end face of the core rod 101 against the bottom surface of the placement hole 103a, and then fix the core rod 101 and the fixing plate 103 by screws, and then grind the other end face of the core rod 101, so that the end faces of multiple core rods 101 can be ground at the same time, which is more efficient.
