[0002] In the production process of refrigeration pipe fittings of equipment such as refrigerators and air conditioners, such as freezing evaporators, condensers, finned evaporators, etc., copper pipes are usually used as the main refrigeration parts. In order to facilitate the transportation of copper pipes, the copper pipes are usually wound. Therefore, before processing the copper pipes, it is necessary to straighten the copper pipes first, and then cut them. After the copper pipes are cut, there will be burrs at the ends, which may scratch the hands of workers during subsequent processing, and it is not convenient for subsequent welding and other operations. Therefore, the ports of copper pipes are usually ground after the cutting process. In the prior art, the ports of copper pipes are usually ground manually, that is, the copper pipes are manually taken and ground with a grinding wheel. Although the grinding efficiency is relatively high, the grinding quality of the ports of copper pipes is completely controlled by the proficiency of workers. Once a mistake occurs, it may cause air holes in the subsequent welding process of copper pipes, thereby affecting the product quality and being not conducive to standardized control during the processing process.

[0020] Figure 5 For Figure 4 Enlarged schematic diagram at position A of Detailed implementation manners

[0021] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will describe the implementation manners of the present utility model in detail with reference to the accompanying drawings. However, the embodiments described herein are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] As Figures 1 - 3 shown, this embodiment provides a pipe fitting port grinding tooling, including: a workbench 100, a transfer component 200, and a grinding component 300.

[0023] On the top surface of the workbench 100, there are two limiting plates 101 located at both ends in the length direction and moving towards each other. Along the length direction of the workbench 100, there are a plurality of through grooves 106, and the length direction of the through grooves 106 is parallel to the width direction of the workbench 100. Between the limiting plates 101, there are a plurality of convex strips 102. On the top surface of the convex strips 102, there are a plurality of first card slots 103 for carrying pipe fittings. The transfer component 200 includes a plurality of moving plates 201 passing through the through grooves 106. On the moving plates 201, there are a plurality of second card slots 202 along their length direction, and they move along the vertical direction and the width direction of the workbench 100 for transferring pipe fittings. The grinding component 300 includes two grinding blocks 301 respectively arranged at one end of the workbench 100 and moving towards each other. The grinding blocks 301 rotate around their own axes for grinding the pipe fitting ports. Between the grinding blocks 301, there is a pressing block 302 moving along the vertical direction for pressing the pipe fittings.

[0024] Specifically, on both sides in the length direction of the workbench 100, there are inclined surfaces. The inclined surface close to the grinding component 300 slopes downward, and the inclined surface close to the transfer component 200 slopes upward. When placing the pipe fitting on the workbench 100, under the action of its own gravity, the pipe fitting closest to the center of the workbench 100 will abut against one end of the convex strip 102, and at this time, the pipe fitting closest to the center of the workbench 100 is located in the area of the through groove 106, so as to facilitate the moving plate 201 to lift and transfer it. After grinding, the pipe fitting will also be lifted by the transfer plate 201 and placed on the downward-sloping inclined surface, so that the ground pipe fitting slides downward under the action of its own gravity and thus falls from the workbench 100.

[0025] Specifically, the upper end of the limit plate 101 is sleeved on the bidirectional screw 104. The bidirectional screw 104 is rotatably installed on the bracket 105, and the bracket 105 is installed on the workbench 100. By rotating the bidirectional screw 104, the two limit plates 101 can move towards each other or away from each other, so as to adapt to pipe fittings of different lengths.

[0026] Specifically, the lower end of the moving plate 201 is installed on the connecting plate 203. Both sides of the connecting plate 203 are sleeved on the sliding rods 204, and the sliding rods 204 are installed on the side frames 205. The side frames 205 are connected to the moving end of the horizontal linear mechanism. The horizontal linear mechanism is installed at the bottom of the workbench 100. Two chutes 206 are provided along the length direction of the connecting plate 203. Sliding blocks 207 are slidably engaged in the chutes 206. The sliding blocks 207 are connected to the moving end of the first vertical lifting mechanism. The first vertical lifting mechanism is installed on the bottom frame 208, and the bottom frame 208 is installed at the bottom of the workbench 100. When it is necessary to move the pipe fitting, the horizontal linear mechanism is used to drive the moving plate 201 to the end of the through groove 106 away from the grinding assembly 300. Relative sliding will occur between the sliding block 207 and the connecting plate 203. And at this time, the top surface of the moving plate 201 is lower than the top surface of the workbench 100. Then, the first vertical lifting mechanism is used to drive the moving plate 201 to move upward. At this time, relative sliding will occur between the connecting plate 203 and the sliding rods 204, so that the pipe fitting is located in the second card slot 202, thereby lifting the pipe fitting. Then, the horizontal linear mechanism is used again to drive the moving plate 201 to move towards the end of the through groove 106 close to the grinding assembly 300. After that, the moving plate 201 is moved downward until the upper end of the moving plate 201 is lower than the top surface of the workbench 100. At this time, the pipe fitting will be located in the first card slot 103, thereby realizing the transfer of the pipe fitting. In this way, by repeating the cycle, the pipe fitting can be moved to the first card slot 103 closest to the grinding assembly 200. After that, the grinding operation on the port of the pipe fitting can be started.

[0027] Specifically, the grinding block 301 is detachably mounted on the rotating shaft 303. For example, it can be connected by threads or snap connections, so as to facilitate the replacement of the grinding block 301 according to pipes with different diameters. The rotating shaft 303 is rotatably mounted on the side plate 304. The upper end of the side plate 304 passes through the support frame 305 and is sleeved on the cross bar 306. The support frame 305 is mounted on the workbench 100. Both ends of the cross bar 306 are connected to the moving end of the second vertical lifting mechanism. One side of the side plate 304 is slidably matched with the moving block 307. The moving block 307 is connected to the moving end of the bidirectional linear mechanism. Both the second vertical lifting mechanism and the bidirectional linear mechanism are mounted on the support frame 305. When it is necessary to grind the ports of pipes with different diameters, the distance between the axis of the pipe and the top surface of the workbench 100 will change. At this time, the second vertical lifting mechanism is used to drive the cross bar 306 to move up and down, so as to adjust the distance between the grinding block 301 and the top surface of the workbench 100 to adapt to pipes with different diameters. Then, the two side plates 304 can be driven to move towards each other by the bidirectional linear mechanism to start the subsequent grinding operation.

[0028] Specifically, a first rotating ring 308 is sleeved on the rotating shaft 303. The first rotating ring 308 is driven by a belt to drive the second rotating ring 309. The second rotating ring 309 is rotatably mounted on the side plate 304 and is sleeved on the transmission shaft 310. The transmission shaft 310 is rotatably mounted on the support frame 305 and one end is connected to the output end of the power device. Since relative sliding will occur between the transmission shaft 310 and the second rotating ring 309, in order to ensure power transmission, a keyway fit can be adopted between the transmission shaft 310 and the second rotating ring 309. By using the power device, the grinding block 301 can be driven to rotate to start grinding the port of the pipe. And the end of the grinding block 301 can be set as an inward concave arc, so that a chamfer can be ground on the port of the pipe, which is more convenient for the subsequent welding operation.

[0029] Specifically, a V-shaped groove 311 is provided on the bottom surface of the pressing block 302 for clamping the pipe. The upper end of the pressing block 302 is connected to the moving end of the telescopic rod 312. The telescopic rod 312 is mounted on the support frame 305. By using the telescopic rod 312, the pressing block 302 can be driven to move downward, so as to clamp the pipe and prevent it from rotating together with the grinding block 301 during the grinding process, ensuring the smooth progress of the grinding operation.

[0030] Specifically, both ends of the through groove 106 extend beyond the ends of the convex strip 102, and the length of the moving plate 201 is greater than the length of the convex strip 102. The number of the second card slots 202 on the moving plate 201 is greater than the number of the first card slots 103 on the adjacent convex strip 102, which is convenient for transferring the pipe and also ensures that the moving plate 201 can smoothly move the pipe out of the first card slot 103.

[0031] More specifically, a baffle 107 is further provided between the limit plates 101. The baffle 107 is located above the upwardly inclined slope and is used to block excessive pipe fittings, so that the pipe fittings are arranged in a row, avoiding the accumulation of pipe fittings. Moreover, a screw 108 is provided on the top surface of the baffle 107. The screw 108 passes through the bracket 105 and is locked with a nut, so that the height of the baffle 107 can be adjusted according to the diameter of the pipe fittings.

[0032] Since the above is only the preferred embodiment of the present invention and is not used to limit the present invention, obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and modifications.
