DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0021] Reference Figure 1 , a grinding device suitable for a plunger, comprising a workbench 1 and a driving mechanism and a grinding mechanism mounted on the workbench 1, the driving mechanism comprising a support 2, a limiting portion 3, a limiting portion 4, an electric cylinder 5, a support 6, a limiting portion 7, a connecting shaft 8, a limiting portion 9, a gear ring 10, a gear 11 and a motor 12, the support 2 is movably mounted on the workbench 1, the output end of the electric cylinder 5 is fixedly connected to the support 2, the limiting portion 3 is rotatably mounted on the support 2, the limiting portion 4 is two, which rotate on the limiting portion 3 opposite to each other in upper and lower directions, the support 2 6 is mounted on the workbench 1 and opposite to the support 2, the limiting portion 2 7 is rotatably mounted on the support 2 6, the connecting shaft 8 is fixedly connected to the limiting portion 2 7, the limiting portion 2 9 is two, which rotate on the limiting portion 2 7 opposite to each other in upper and lower directions, the gear ring 10 is fixedly mounted on the connecting shaft 8, the gear 11 is mounted at the output end of the motor 12 and meshes with the gear ring 10 for transmission;

[0022] The grinding mechanism includes a slide rail 13, a bracket 14, a grinder 15, a spring 16, a mounting frame 17 and a swing arm 18. The slide rail 13 is installed on the workbench 1, the bracket 14 is slidably set on the slide rail 13, the mounting frame 17 slides up and down on the bracket 14, the grinder 15 is installed on the mounting frame 17, the spring 16 is installed between the upper end of the mounting frame 17 and the bracket 14, and the swing arm 18 is movably connected to the bracket 14 through a hinge seat, and one end of the swing arm 18 is hinged to the middle part of the upper end of the mounting frame 17;

[0023] Place one end of the plunger against the middle of the inner side of the second limiting part 7, then drive the electric cylinder 5 to pull the support 2 to move, so that the other end of the plunger is in contact with the middle of the inner side of the limiting part 3. The two ends of the plunger are clamped by the second limiting part 7 and the limiting part 3, and then the limiting part 4 is rotated to clamp the plunger.

[0024] The driving motor 12 drives the gear 11 to rotate, and the gear 11 drives the connecting shaft 8 to rotate through the gear ring 10. The connecting shaft 8 then drives the limiting part 2 7 to rotate synchronously. Because the plunger is clamped between the limiting part 2 7 and the limiting part 1 3, the limiting part 1 3 assists the rotation on the support 1 2, thereby ensuring stable rotation of the plunger.

[0025] At this time, the grinder 15 can be driven and the handle 19 can be held to push the bracket 14 to move along the slide rail 13, and the swing arm 18 can be lifted upward. One end of the swing arm 18 presses the mounting frame 17 downward, and then the mounting frame 17 drives the grinder 15 to move downward, so that the grinding end of the grinder 15 contacts the plunger to start grinding;

[0026] The device is manually controlled, and can polish in real time according to the size change of the plunger.

[0027] The limiting part one 3 and the limiting part two 7 are both hollow circular table structures, and the limiting part one 3 and the limiting part two 7 are opposite, and the center point of the limiting part one 3 and the center point of the limiting part two 7 are on the same straight line; when placing the plunger, one end of the plunger can be placed in the center position of the limiting part two 7, and when the limiting part one 3 approaches the limiting part two 7, the other end of the plunger is placed in the center of the limiting part one 3, so that the plunger is stably limited between the limiting part one 3 and the limiting part two 7; therefore, after the plunger is positioned, it is not necessary to keep it completely on the central axis of the limiting part one 3 and the limiting part two 7, and the polishing process can still be carried out.

[0028] The upper end surface of the workbench 1 is provided with a sliding groove, the support one 2 slides along the sliding groove, and the support two 6 is fixed on the workbench 1; when placing the plunger, the distance between the support one 2 and the support two 6 can be adjusted to position the plunger.

[0029] The two side surfaces of the support 14 are also provided with a hand-held part 19; when polishing the plunger, the hand-held part 19 can be held to push the support 14 to move along the sliding rail 13, adjust the position of the polisher 15, and polish the plunger.

[0030] The limiting part one 4 and the limiting part two 9 are both composed of a screw rod and a clamping plate, and the clamping plate is rotationally connected with the screw rod.

[0031] After placing the plunger, the limiting part one 4 and the limiting part two 9 can be rotated, and the plunger is further limited by the clamping plate at the bottom of the limiting part one 4 and the limiting part two 9, so that the plunger is stably limited between the limiting part one 3 and the limiting part two 7.

[0032] The above-described embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the application. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
