[0027] According to this specific implementation, the workbench 101 is used to install the grinding assembly 102 .

[0028] Among them, the bracket 103 is fixedly connected to the workbench 101 and is located on the top of the workbench 101; the hydraulic cylinder 104 is fixedly connected to the bracket 103 and is located on one side of the bracket 103; the protective cover 105 is fixedly connected to the output end of the hydraulic cylinder 104 and is located at the bottom of the hydraulic cylinder 104; the grinder 106 is arranged inside the protective cover 105; the glass window 107 is fixedly connected to the protective cover 105 and is located on one side of the protective cover 105; the clamping mechanism 108 is arranged on the workbench 101; the mounting mechanism 109 is arranged at the bottom of the workbench 101; the collecting tube 110 is arranged on one side of the mounting mechanism 109. There is a hole in the middle of the workbench 101, and waste chips can directly fall into the collecting tube 110 from the hole. The collecting tube 110 is detachably installed at the bottom of the workbench 101 through the mounting mechanism 109 to collect waste chips. The grinder 106 is arranged in the protective cover 105. There are notches on both sides of the protective cover 105 to adapt to the clamping mechanism 108, and the protective cover 105 will not be blocked by the clamping mechanism 108 when moving downward; when grinding the cut end of the valve seat, the valve seat is clamped by the clamping mechanism 108, and then the hydraulic cylinder 104 is started, and the hydraulic cylinder 104 drives the protective cover 105 to move downward, and the entire valve seat is covered. The protective cover 105 is used to cover the valve seat, and a part of the clamping mechanism 108 is also covered by the protective cover 105. The grinder 106 is started to grind the valve seat, and the internal grinding condition can be observed through the glass window 107. The grinding waste is intercepted from the side by the protective cover 105, and some of the waste will directly fall into the collecting tube 110 from the middle hole of the workbench 101. After the grinding is completed, the protective cover 105 is moved upward, the valve seat is removed, and the waste is swept into the collecting tube 110. With the above method, the protective cover 105 is used to intercept the flying waste during grinding, thereby avoiding the problem of waste flying everywhere during grinding.

[0029] Secondly, the guide rail 111 is fixedly connected to the workbench 101 and is located at the bottom of the workbench 101; the two sliders 112 are respectively slidably connected to the guide rail 111 and are respectively located on one side of the guide rail 111; the double-threaded screw 113 is rotatably connected to the guide rail 111 and is respectively threadedly connected to the two sliders 112 and passes through the two sliders 112 respectively; the two connecting rods 114 are respectively fixedly connected to the two sliders 112 and are respectively slidably connected to the workbench 101 and pass through the workbench 101 respectively; the two support rods 115 are respectively fixedly connected to the two connecting rods 114 and are respectively located on one side of the two connecting rods 114.

When clamping the valve seat, the valve seat is sleeved on the two push rods 115, and the bottom end is supported by the two connecting rods 114. The double-threaded screw 113 is rotated so that the two sliders 112 drive the two push rods 115 to move away from each other through the two connecting rods 114 until the two push rods 115 are tightly pressed against the two sides of the inner wall of the valve seat, thereby clamping the valve seat; friction pads can be provided on the sides of the push rods 115 to increase the friction force and clamp the valve seat more stably; the notches on both sides of the protective cover 105 are adapted to the connecting rod 114. After the protective cover 105 moves down, the connecting rod 114 passes through the notch, and the top of the connecting rod 114 contacts the top of the notch.

[0030] Meanwhile, the motor 116 is fixedly connected to the guide rail 111 and is located at one side of the guide rail 111; the output end of the motor 116 is fixedly connected to the double-threaded screw 113. The motor 116 is used to drive the double-threaded screw 113 to rotate conveniently and labor-savingly.

[0031] In addition, the two mounting ears 117 are respectively fixedly connected to the collecting tube 110 and are respectively located at the sides of the collecting tube 110; the two screws 118 are respectively threadedly connected to the workbench 101 and respectively pass through the two mounting ears 117. The mounting ears 117 are installed at the bottom of the workbench 101 by the screws 118, and the two mounting ears 117 support the collecting tube 110.

[0032] The valve seat cutting end processing equipment described in this embodiment, when grinding the cutting end of the valve seat, the valve seat is clamped by the clamping mechanism 108, and then the hydraulic cylinder 104 is started. The hydraulic cylinder 104 drives the protective cover 105 to move downward to cover the entire valve seat, and a part of the clamping mechanism 108 is also covered by the protective cover 105. The grinder 106 is started to grind the valve seat, and the internal grinding condition can be observed through the glass window 107. The grinding waste is intercepted from the side by the protective cover 105, and some of the waste will directly fall into the collecting tube 110 from the middle hole of the workbench 101. After the grinding is completed, the protective cover 105 is moved upward, the valve seat is removed, and the waste is swept into the collecting tube 110. In the above manner, when grinding, the protective cover 105 is used to intercept the flying waste, so as to avoid the problem of waste flying everywhere during grinding.

[0034] Based on the first embodiment, please refer to Figure 5 ,in, Figure 5 It is a schematic diagram of the overall structure of the second embodiment of the utility model.

[0035] The valve seat cutting end processing equipment provided by the utility model further includes two guide mechanisms 201 ; the guide mechanism 201 includes a sleeve 202 and a slide rod 203 .

[0036] According to this specific embodiment, the two guide mechanisms 201 are respectively arranged on the top of the protective cover 105. When the output end of the hydraulic cylinder 104 drives the protective cover 105 to move downward, it will inevitably be affected by the horizontal force and rotate, thereby causing the protective cover 105 to rotate, resulting in the two notches being unable to align with the two connecting rods 114, causing the protective cover 105 to interfere with the two connecting rods 114 when moving downward. Therefore, two guide mechanisms 201 are arranged to guide the protective cover 105 so that the protective cover 105 can only be lifted and lowered vertically.

[0037] The sleeve 202 is fixedly connected to the bracket 103 and is located on one side of the bracket 103; the slide bar 203 is slidably connected to the sleeve 202 and is fixedly connected to the protective cover 105 and is located inside the sleeve 202. When the hydraulic cylinder 104 drives the protective cover 105 to rise and fall, the slide bar 203 slides and rises inside the sleeve 202 to guide the protective cover 105 so that the protective cover 105 can only rise and fall vertically without rotating.

[0038] In the valve seat cutting end processing equipment described in this embodiment, when the hydraulic cylinder 104 drives the protective cover 105 to rise and fall, the slide rod 203 slides and rises in the sleeve 202 to guide the protective cover 105, so that the protective cover 105 can only rise and fall vertically and will not rotate.
