Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, specifically to a polishing device for irregularly shaped metal tubes of engines. Background Technology

[0002] Engine-shaped metal tubes are special pipes used inside engines. Their shapes are non-standard and customized according to the specific design of the engine. These pipes are made of high-strength, high-temperature resistant metal materials, which can withstand extreme working environments and pressures, ensuring the normal operation and high efficiency of the engine.

[0003] Due to the special shape of irregular metal tubes, it is usually inconvenient to clamp and position them during grinding and polishing. As a result, the stability of the irregular metal tubes is poor during grinding, which may affect the uniformity of grinding. Therefore, a polishing device for irregular metal tubes of engines is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-5 As shown, a polishing device for irregularly shaped metal tubes of an engine includes a grinding mechanism 1, with a clamping mechanism 2 disposed above the grinding mechanism 1. The grinding mechanism 1 includes an electric cylinder 108 and a motor 113. The clamping mechanism 2 includes a mounting frame 201, with a clamping groove 202 in the middle of the mounting frame 201. Lead screws 203 are rotatably connected to both sides of the outer wall of the mounting frame 201. A knob 204 is fixedly connected to the top of each lead screw 203, and a clamping block 2 is threaded onto the outer wall of the lead screw 203. 05. One end of the clamping block 205 extends into the interior of the mounting frame 201, and the side edge of the clamping block 205 is slidably connected to the clamping groove 202; wherein, a slider 206 is fixedly mounted on the top of the mounting frame 201, and positioning shafts 207 are symmetrically slidably connected to the outer wall of the slider 206, and springs 208 are fixedly connected to the outer wall of each positioning shaft 207, the other end of the springs 208 being fixedly connected to the inner side of the slider 206; wherein, abutment shafts 209 are fixedly connected to both ends of the inner wall of the slider 206, such as... Figure 3As shown, the spring 208 pulls the positioning shaft 207 to move inward toward the slider 206;

[0028] A rotating disk 210 is rotatably connected to the middle of the inner wall of the slider 206. An extrusion block 211 is fixedly connected to both sides of the outer wall of the rotating disk 210. The side of the extrusion block 211 abuts against the end of the positioning shaft 207. The other side of the extrusion block 211 is also in contact with the abutment shaft 209. A knob 212 is fixedly connected to the middle of the top of the rotating disk 210. The top of the knob 212 extends to the top of the slider 206. As shown in the figure, after the abutment shaft 209 contacts the extrusion block 211, the extrusion block 211 pushes the positioning shaft 207 completely outward of the slider 206, thereby achieving the positioning function of the abutment shaft 209.

[0029] The grinding mechanism 1 includes a support foot 101. A base plate 102 is fixedly installed on the top of the support foot 101. Columns 103 are symmetrically fixedly installed on both sides of the top surface of the base plate 102. A top plate 104 is fixedly installed at the top end of each column 103. A groove 105 is formed on the top surface of the top plate 104. Several positioning grooves 106 are formed on both sides of the groove 105 on the top surface of the support foot 101. An opening 107 is also formed on the surface of the support foot 101 inside the groove 105. The inner side of the groove 105 is slidably connected to a slider 206, and the inner side of the groove 105 supports the slider 206 as a whole. The inner side of the positioning groove 106 is inserted into a positioning shaft 207. The inner side of the opening 107 is connected through to the mounting frame 201. Figure 5 As shown, after the end of the positioning shaft 207 extends out and is inserted into the positioning groove 106, the position of the slider 206 remains fixed.

[0030] The bottom surface of the base plate 102 is fixedly installed with the electric cylinder 108 at the center. The extension end of the electric cylinder 108 passes through the base plate 102 and is fixedly connected to the lifting plate 109. One side end of the lifting plate 109 is threaded with a bolt 110. The top of the lifting plate 109 is rotatably connected to a clamping frame 111. Slots 112 are provided around the bottom surface of the clamping frame 111. The inner side of the slots 112 is inserted into the top of the lifting plate 109. Figure 1 As shown, for every 90 degrees that the clamping frame 111 rotates on the lifting plate 109, a slot 112 is aligned vertically with the bolt 110;

[0031] One side of the clamping frame 111 is fixedly installed with the motor 113. The output shaft of the motor 113 passes through the clamping frame 111 and is fixedly connected to the grinding roller 114. The other end of the grinding roller 114 is rotatably connected to the inside of the clamping frame 111.

[0032] The working principle of this utility model:

[0033] When using the device, first adjust the distance between the two mounting frames 201. Rotate knob 212 to drive the rotating disk 210 and the pressing block 211 to rotate, thereby separating the positioning shaft 207 from the pressing block 211. The spring 208 pushes the positioning shaft 207 to move towards the pressing block 211, and the positioning shaft 207 retracts into the slider 206. At this time, the slider 206 is pushed to move along the slide groove 105. When it needs to be fixed, rotate knob 212 in the opposite direction to reset it. Then the pressing block 211 pushes one end of the positioning shaft 207 out of the surface of the slider 206 again, and the end of the positioning shaft 207 is inserted into the positioning groove 106, thus locking the position of the slider 206.

[0034] Next, the metal tube is inserted into the clamping groove 202, and then the knob 204 is rotated to drive the lead screw 203 to rotate. The thread on the surface of the lead screw 203 pushes the clamping block 205 to rise and fall along the inner side of the clamping groove 202, thereby clamping and fixing the surface of the metal tube. Then, the electric cylinder 108 lifts the clamping frame 111 through the lifting plate 109, and the grinding roller 114 contacts the surface of the metal tube. The motor 113 drives the grinding roller 114 to rotate and grind and polish the surface of the metal tube. In addition, after loosening the bolt 110 to separate it from the slot 112, the clamping frame 111 can be rotated on the top of the lifting plate 109, thereby driving the grinding roller 114 to rotate 90 degrees. At this time, the contact area between the grinding roller 114 and the metal tube is reduced. Tighten the bolt 110 to insert it into the slot 112, thereby fixing the clamping frame 111 and the lifting plate 109 relatively.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
