DETAILED DESCRIPTION

[0014] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0015] In the following description, specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in a variety of other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0016] like Figure 2 As shown, the rubber strip head grinder of the present invention comprises a workbench 1, a grinding part 2 and a clamping part 3, wherein the workbench 1 is fixed on a base 5, and the base 5 supports the workbench 1. The grinding part 2 and the clamping part 3 are both arranged on the workbench 1, the grinding part 2 is fixed on the workbench 1, and the clamping part 3 is used to clamp the door sealing rubber strip.

[0017] The grinding part 2 includes a grinding wheel 201 and a housing 202. The grinding wheel 201 is connected to a motor through a rotating shaft fixed at the center thereof. When the motor is working, the grinding wheel 201 is driven to rotate. The grinding wheel 201 is arranged in the housing 202. The housing 202 is fixed on the workbench 1. The housing 202 is provided with an opening on one side facing the clamping part 3 so that part of the grinding wheel 201 at the opening can leak out. The clamping part 3 is arranged corresponding to the opening on the side of the housing so that the grinding wheel at the opening can grind the door seal strip clamped by the clamping part 3.

[0018] The clamping part 3 includes a reciprocating mechanism and a rubber strip clamping mechanism, the reciprocating mechanism includes a moving plate 306, a slide, a swing plate 309 and a handle 310, and the rubber strip clamping mechanism is arranged at one end of the moving plate 306 facing the grinding part 2. The slide in this embodiment includes two parallel fixed plates 304, the fixed plate 304 is fixed on the workbench 1, the fixed plate 304 includes a vertical plate and a horizontal plate, the bottom of the vertical plate is fixedly connected to the workbench 1, the top of the vertical plate is fixedly connected to the horizontal plate, and a slide is formed between the horizontal plate and the workbench 1, and the two side edges of the moving plate 306 along the length direction are respectively arranged in the slide between the two fixed plates 304 and the workbench 1, and can slide in the slide. One end of the swing plate 309 is fixedly connected to the handle 310, and the other end of the swing plate 309 is hinged to the movable plate 306 through the hinge Ⅰ305. The middle part of the swing plate 309 is hinged to the fixed plate 304 through the hinge Ⅱ308. When the operator uses it, he holds the handle 310 to change the position of the handle 310. At this time, the swing plate 309 fixedly connected to the handle swings along the hinge Ⅱ308. During the swinging process, the other end of the swing plate 309 drives the movable plate 306 to change its position through the hinge Ⅰ305. Under the restriction of the horizontal slideways of the fixed plates on both sides, the movable plate 306 can only move back and forth along the slideways. When grinding, turn the handle 309 to make the rubber strip clamping part close to the grinding wheel; after the grinding work is completed, turn the handle to make the rubber strip clamping part away from the grinding wheel.

[0019] A rubber strip clamping mechanism is provided at one end of the movable plate 306, and a limit plate 311 is fixed to the other end of the movable plate 306. A limit screw 307 is provided on the limit plate arranged in the vertical direction, and one end of the limit screw 307 passes through the limit plate 311 and contacts the side of the workbench 1. When the movable plate 306 moves toward the grinding part, when the movable plate 306 moves to the point where one end of the limit screw 307 contacts the side of the workbench, the movable plate 306 cannot continue to move under the blocking effect of the limit screw 307, thereby ensuring that the rubber strip clamping mechanism and the grinding wheel can be kept within a reasonable distance range, and preventing the distance between the rubber strip clamping mechanism and the grinding wheel from being too close, thereby affecting the grinding effect of the door seal rubber strip. Therefore, the limit screw 307 can not only keep the rubber strip clamping mechanism and the grinding wheel at an appropriate distance, but also fix the rubber strip clamping mechanism at the most suitable position, thereby ensuring the grinding effect of the door seal rubber strip.

[0020] The rubber strip clamping mechanism includes an upper clamping plate 301, a middle clamping plate 302 and a bottom clamping plate 303. The bottom clamping plate 303 includes a horizontal clamping plate and a vertical fixing plate. The vertical fixing plate is fixed to the top surface of the horizontal clamping plate. The horizontal clamping plate is fixed to the side of the movable plate 306 facing the shell opening. The upper clamping plate 301 and the middle clamping plate 302 are fixed to the side of the vertical fixing plate facing the grinding part from top to bottom. There is a certain gap between the upper clamping plate 301 and the middle clamping plate 302 to facilitate the insertion of the side rubber strip I401 of the door seal rubber strip into the upper clamping plate 30 1 and the middle clamping plate 302, and there is a certain gap between the middle clamping plate 302 and the horizontal clamping plate, so that the side rubber strip II 402 of the door seal rubber strip can be inserted between the middle clamping plate 302 and the horizontal clamping plate, and the door seal rubber strip is in transitional fit with the upper clamping plate 301, the middle clamping plate 302 and the bottom clamping plate 303, that is, a certain external force must be applied to insert the door seal rubber strip into the above gap; after the door seal rubber strip is inserted into the above gap, it can be fixed on the rubber strip clamping mechanism, so as to ensure that the position of the door seal rubber strip will not change during the grinding process. That is, the rubber strip clamping mechanism can realize the placement and extraction of the rubber strip, and can also fix the position of the door seal rubber strip.

[0021] The working process of the present invention is as follows: when it is necessary to grind the two ends of the door seal strip, first insert the head of the door seal strip into the gap formed by the strip clamping mechanism, and the strip clamping mechanism clamps the door seal strip through the transition between the gap and the door seal strip. Then the operator shakes the handle 310, and the swing plate 309 fixedly connected to the handle 310 swings along the hinge II 308. During the swinging process, the other end of the swing plate 309 drives the moving plate 306 along the slideway formed by the fixed plate through the hinge I 305, and moves toward the grinding part. When the moving plate 306 moves to the point where the limit screw contacts the side of the workbench, the moving plate 306 stops moving. Since the rubber strip clamping mechanism faces the opening of the housing, when the door seal rubber strip clamped by the rubber strip clamping mechanism contacts the rotating grinding wheel, the grinding wheel grinds the turning edge of the intersection of the side rubber strip I 401 and the side rubber strip II 402, and the turning edge of the intersection of the side rubber strip III 403 and the side rubber strip II 402. After grinding, swing the handle 310 to make the rubber strip clamping mechanism away from the grinding part, remove one side head of the door seal rubber strip from the rubber strip clamping mechanism, insert the other side head into the rubber strip clamping mechanism, and grind according to the above steps.

[0022] The above is a detailed introduction to the rubber strip head grinder provided by the present invention.
