It is equipped with a bidirectional clamping clamp, which can be used to meet the processing needs of pipe fittings of different diameters. However, when grinding the end face, it only grinds one side by grinding wheel, which easily forms burrs at the junction of the end face and the inner and outer walls, affecting the quality of the finished product and even potentially cutting the user. Utility Model Content

[0025] Please see Figure 1-7 The present invention provides the following technical solution:

[0026] A stainless steel hollow tube end face grinding device includes a worktable 1, a feed mechanism 3 is installed on the worktable 1, and a plurality of clamping components 4 are installed on the output end of the feed mechanism 3. The clamping components 4 are used to clamp the tube to be processed. The feed mechanism 3 can drive the tube to move on the worktable, thereby controlling the grinding feed amount.

[0027] A grinding motor 5 is installed on the worktable 1. A grinding assembly 6 is connected to the output shaft of the grinding motor 5. The grinding assembly 6 and the clamping assembly 4 are arranged coaxially. The grinding assembly 6 includes a grinding wheel 61, which is parallel to the end face of the pipe to be processed. Two grinding columns 65 are slidably connected to the grinding wheel 61. The grinding columns 65 are arranged in a direction perpendicular to the grinding wheel 61. The two grinding columns 65 can abut against the inner wall and outer wall of the pipe to be processed, respectively. When the grinding assembly 6 is working, the grinding wheel 61 and the two grinding columns 65 simultaneously grind the end face of the pipe to be processed and the inner and outer wall edges at the end face. The edge position is ground in a wrap-around manner, avoiding the generation of burrs when grinding on one side.

[0028] The workbench 1 is equipped with a waste chip suction component 7 and a grinding fluid nozzle 8, which can spray grinding fluid onto the grinding surface during grinding to improve the grinding effect. At the same time, it can suck in the air at the grinding area to reduce the splashing of waste chips generated during grinding. The workbench 1 is covered with a shell 2. When grinding, the shell 2 is placed on the grinding component 6 to prevent the splashing of grinding fluid and waste chips and maintain a clean environment.

[0029] The grinding wheel 61 is mounted on the output shaft of the grinding motor 5. Two radial grooves 62 are formed on the grinding wheel 61, and the two grooves 62 are symmetrically arranged. Two grinding columns 65 are slidably connected to the two grooves 62 respectively. Two connecting blocks 63 are symmetrically arranged on the side of the grinding wheel 61 facing the grinding motor 5. The two connecting blocks 63 are located on the edge of the grinding wheel 61. An adjusting rod 64 is threaded onto the connecting block 63. The adjusting rod 64 is arranged in the same direction as the groove 62. The grinding column 65 passes through the grinding wheel 61 and is rotatably connected to the adjusting rod 64 on the corresponding side. A handle is provided at the end of the adjusting rod 64 away from the grinding wheel 65. Rotating the adjusting rod 64 can drive the grinding column 65 to move in the groove 62, thereby changing the relative position of the grinding column 65 and the pipe to be processed, until the two grinding columns 65 abut against the inner wall and outer wall of the pipe to be processed respectively.

[0030] The end of the grinding column 65 facing away from the grinding motor 5 is set in a conical shape. When processing pipes of uniform specifications, the position of the grinding column 65 can be fixed. The conical shape of the end of the grinding column 65 makes it easy for the pipe to move towards the grinding wheel 61 and connect with the two grinding columns 65. This avoids the pipe being stuck by the end face of the grinding column 65 due to errors, ensuring that the pipe is properly engaged with the grinding assembly 6, which facilitates the grinding operation.

[0031] The clamping assembly 4 includes a fixed frame 41, which is fixed to the output end of the feed mechanism 3. A rotating ring 42 is rotatably connected to the fixed frame 41. The fixed frame 41 extends from one side of the rotating ring 42. Several external teeth 421 are provided on the outer wall of one end of the fixed frame 41 at the extension of the rotating ring 42. A clamping motor 44 is mounted on the fixed frame 41. A gear 43 is connected to the output shaft of the clamping motor 44. The gear 43 meshes with the external teeth 421. Several clamping rods 45 are slidably connected to the rotating ring 42 in the radial direction. Several extrusion grooves are provided on the fixed frame 41. 411, clamping rod 45 corresponds to extrusion groove 411, one end of clamping rod 45 abuts against the bottom of extrusion groove 411, the other end of clamping rod 45 extends through rotating ring 42 toward the axis, one end of clamping rod 45 away from the axis is connected to spring 46, spring 46 is sleeved on clamping rod 45, the other end of spring 46 abuts against rotating ring 42, several extrusion grooves 411 and clamping rod 45 are symmetrically arranged about rotating ring 42, the bottom of extrusion groove 411 is involute, and the bottom of extrusion groove 411 extends outward from the outer wall of rotating ring 42;

[0032] When the clamping motor 44 starts, it drives the external teeth 421 through the gear 43 to make the rotating ring 42 rotate. When the rotating ring 42 rotates, it drives the clamping rod 45 to move synchronously. The outer end of the clamping rod 45 is pushed by the bottom of the extrusion groove 411 and moves towards the axis, thereby clamping the pipe to be processed in the middle, so that the axis of the pipe is the same as the axis of the rotating ring 42, that is, the pipe and the grinding assembly 6 are coaxial, which facilitates the subsequent grinding of the pipe.

[0033] When the pipe needs to be removed after processing, the clamping motor 44 reverses and the clamping rod 45 moves to the large diameter end of the extrusion groove 411. Under the action of the spring 46, the clamping rod 45 moves away from the axis, thereby releasing the clamp on the pipe and allowing the pipe to be removed.

[0034] Specifically, grinding columns 65 are provided on both sides of the grinding wheel 61, and the grinding columns 65 are arranged in a direction perpendicular to the grinding wheel 61. Two connecting blocks 63 are symmetrically arranged on the rear side of the grinding wheel 61. An adjusting rod 64 is threaded onto the connecting block 63. The adjusting rod 64 is rotatably connected to the grinding column 65. Two sliding grooves 62 are symmetrically opened on the grinding wheel 61 in the radial direction. By rotating the adjusting rod 64, the grinding column 65 can be moved within the sliding groove 62, thereby adjusting the position of the grinding column 65 so that the two grinding columns 65 abut against the inner and outer walls of the pipe to be processed, respectively. When the grinding wheel 61 rotates, the two grinding columns 65 grind the inner and outer walls of the pipe to be processed simultaneously. The grinding wheel 61, which grinds the end face, can perform a wrap-around grinding of the pipe, thereby avoiding the generation of burrs at the edges and improving the quality of the workpiece.
