DETAILED DESCRIPTION
[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the utility model.
[0029] As Figure 1 shown, the utility model provides a kind of polishing device before heat pipe welding, it include: material taking placement rack 1, linkage material taking and discharging mechanism, polishing mechanism;
[0030] Material taking placement rack 1 is roughly a three-dimensional rectangular frame as a whole, and the top surface of the material taking placement rack 1 is provided as a placement surface 2, and the discharge side of the placement surface 2 is provided with a stopper 3; the placement surface 2 is used to place the unpolished heat pipe base pipe 11, and the placement surface 2 is an inclined surface with the feeding side higher than the discharge side, and a layer of heat pipe base pipe 11 is laid on the placement surface 2.
[0031] In actual work, the heat pipe base pipe 11 in the heat pipe base pipe 11 centralized storage is transferred to the placement surface 2 by a crane or other equipment to wait for subsequent welding work. The material taking placement rack 1 can support multiple unpolished heat pipe base pipes 11 at a time, and in actual heat pipe processing, the entire polishing assembly line can have sufficient material source, so that the entire polishing assembly line can continuously work and circulate, reducing idle time, so that the efficiency of the entire heat pipe processing work is higher.
[0032] In order to prevent the heat pipe on the placing surface 2 from directly rolling off, a stopper 3 is arranged at the discharging side of the placing surface 2, and the stopper 3 is used for limiting the heat pipe on the placing surface 2. The stopper 3 is a plurality of blocks or plates protruding from the placing surface 2. In actual use, different heights and radii of the stopper 3 can be selected according to the size of the heat pipe, and the stopper 3 is uniformly installed at the edge of the material taking and placing rack 1 corresponding to the discharging side of the placing surface 2. When the heat pipe rolls to the discharging side of the placing surface 2 under the action of gravity, the heat pipe is limited by the stopper 3, so that the base pipe 11 of the heat pipe is prevented from rolling off.
[0033] As shown in Figure 3 , the polishing mechanism includes a driving wheel 4, a driven supporting wheel 5 and a polishing grinding wheel 6. The driving wheel 4 and the polishing grinding wheel 6 are respectively provided with a driving motor 7. The driving wheel 4 corresponds to the position of the linkage connection structure. The driving wheel 4, the driven supporting wheel 5 and the polishing grinding wheel 6 form a polishing cavity. The polishing grinding wheel 6 is further connected with a forward pushing air pump 19. The forward pushing air pump 19 is used to drive the polishing grinding wheel 6 to move forward and narrow the polishing cavity.
[0034] As shown in Figure 2 , the driving wheel 4 and the polishing grinding wheel 6 form the entrance and exit of the polishing cavity. The gap between the driving wheel 4 and the driven supporting wheel 5 and the gap between the driven supporting wheel 5 and the polishing grinding wheel 6 are smaller than the diameter of the heat pipe base pipe 11. Therefore, when the heat pipe base pipe 11 is polished, it will not be separated from the polishing cavity under the action of gravity. After the polishing grinding wheel 6 is pushed forward by the forward pushing air pump 19, the polishing cavity is narrowed, and the heat pipe base pipe 11 will be more closely attached to the polishing grinding wheel, which has better polishing effect. After polishing is completed, the forward pushing air pump 19 is reset, the polishing grinding wheel 6 is moved backward, the polishing cavity is expanded, and the heat pipe base pipe 11 after polishing is discharged.
[0035] The polishing mechanism is further provided with a polishing support frame 12. The driving wheel 4, the driven supporting wheel 5 and the polishing grinding wheel 6 are respectively provided with a rotating support bracket 13. The stator end of the driving motor 7 of the driving wheel 4 and the rotating support bracket 13 are fixedly installed on the polishing support frame 12. The rotating support bracket 13 of the driven supporting wheel 5 is also fixedly installed on the polishing support frame 12. The stator end of the driving motor 7 of the polishing grinding wheel 6 and the rotating support bracket 13 are fixedly connected. The rotating support bracket 13 of the polishing grinding wheel 6 is slidingly connected with the polishing support frame 12. The rotor end of the driving motor 7 is used to drive the driving wheel 4 or the polishing grinding wheel 6.
[0036] The fixed part of the forward pushing air pump 19 is fixedly connected with the polishing support frame 12. The extending part of the forward pushing air pump 19 is fixedly connected with the rotating support bracket 13 of the polishing grinding wheel 6. When the extending part of the forward pushing air pump 19 extends, the polishing grinding wheel 6 is moved forward.
[0037] The rotating support bracket 13 is used for mounting the driving wheel 4, the driven support wheel 5 and the grinding wheel 6 on the grinding support frame 12, so that both ends of the wheel body are supported and the rotation of the wheel body is not affected. In the utility model, the driving motor 7 and the driving wheel 4 are connected by a synchronous belt, and when the rotor end of the driving motor 7 rotates, the driving wheel 4 is driven to rotate by the belt. The grinding wheel 6 is also driven by another driving motor 7.
[0038] In actual grinding work, when the heat pipe base pipe 11 enters the grinding cavity, the bottom position is limited by the driven support wheel 5, so that the heat pipe base pipe 11 cannot fall from the grinding cavity. When the first driving motor 7 drives the driving wheel 4 to rotate, the heat pipe base pipe 11 is driven to rotate under the action of friction, and the driven support wheel 5 rotates with the heat pipe base pipe 11. The second driving motor 7 drives the grinding wheel 6 to rotate, and the forward pushing air pump 19 drives the grinding wheel 6 to narrow the grinding cavity, so that the grinding wheel 6 and the heat pipe base pipe 11 can have greater relative contact friction, thereby achieving the purpose of grinding rust. After grinding is completed, the forward pushing air pump 19 is reset to release the heat pipe base pipe 11.
[0039] In actual use, according to the actual needs of heat pipe grinding, a corresponding number of grinding mechanisms are arranged on the heat pipe base pipe 11 at the heat pipe outlet side of the material taking and placing frame 1, as shown in the figure, three sets of grinding mechanisms are arranged, and three parts of the same heat pipe base pipe 11 are ground.

Specifically, the top surface of the material taker 9 and the top surface of the material placer 10 are both inclined surfaces with the inlet side higher than the outlet side. In actual implementation, the material taker 9 and the material placer 10 are vertical plates, but since the heat pipe itself is long, a single vertical plate is difficult to stably support, so a plurality of material takers 9 and material placers 10 are arranged on the linkage support frame 15 along the axial direction of the heat pipe, so as to stably support the heat pipe. The outlet side of the material taker 9 and the inlet side of the material placer 10 are connected, and the top surface of the outlet side of the material taker 9 is lower than the top surface of the inlet side of the material placer 10, forming a material blocking step 14, that is, the linkage connection structure. In actual implementation, the material taker 9 and the material placer 10 can be arranged as a whole plate, and the material blocking step 14 can be arranged on the top of the plate. Figure 4 The inlet side of the material taker 9 corresponds to the position of the blocker 3, and the action driver 8 is used to drive the material taker 9 and the material placer 10 to rise or fall at the same time.
[0041]
[0042] When the action driver 8 rises, the material taking device 9 takes the unpolished heat pipe base pipe 11 from the position of the stopper 3, and intercepts the unpolished heat pipe base pipe 11 through the linkage connection structure, and the material discharging device 10 takes the polished heat pipe base pipe 11 from the polishing cavity and discharges the material.
[0043] When the action driver 8 descends, the unpolished heat pipe base pipe 11 intercepted by the linkage connection structure is placed into the polishing cavity.
[0044] The active driving wheel 4 corresponds to the position of the linkage connection structure, and the specific corresponding relationship is that the highest point of the active driving wheel 4 is located on the feeding side of the linkage connection structure, that is, still in the range of the material taking device 9, and the feeding side of the polishing grinding wheel 6 is located on the discharging side of the linkage connection structure, that is, in the position of the material discharging device 10. Figure 5 As shown in the figure, when discharging, the base pipe is lifted by the material discharging device 10, passes through the polishing grinding wheel 6, and is still located on the material discharging device 10, and after being separated from the polishing grinding wheel 6, it will roll down along the inclined surface of the material discharging device 10.
[0045] As an embodiment of the present application, the linkage material taking and discharging mechanism further comprises a linkage support frame 15, the action driver 8 is a jacking air pump with a solenoid valve, the fixed part of the jacking air pump is fixedly connected with the frame body of the linkage support frame 15, the telescopic part of the jacking air pump is fixedly connected with the bottom of the material taking device 9 and the material discharging device 10, and the material taking device 9 and the material discharging device 10 are arranged on the top of the linkage support frame 15, and the action driver 8 can be any structure that can be lifted, and the specific structure type is not limited.
[0046] As an embodiment of the present application, the present application further comprises a polished product placing rack, which is arranged below the discharging side of the material discharging device 10 and is used for centralized transfer and receiving of the polished heat pipe.
[0047] The polishing finished product placing rack comprises a front extension receiving rack 16 and a centralized containing rack 17, the top surface of the front extension receiving rack 16 is provided with a receiving surface with the feeding side higher than the discharging side, the feeding side of the receiving surface is located at the lower position when the discharging device 10 is located at the highest position, and is used for receiving the heat pipe base pipe 11 rolled from the discharging side of the discharging device 10, and the top of the centralized containing rack 17 is provided with a recessed containing groove, and the side close to the receiving surface of the containing groove is provided with a rolling guide slope 18, which is used for obliquely supporting the polished heat pipe base pipe 11 rolled from the front extension receiving rack 16, so as to reduce the damage to the heat pipe.
[0048] It should be noted that the polishing device for heat pipes before welding is a three-dimensional structure, since the heat pipe base pipe 11 is relatively long, the blocker 3, the polishing mechanism, the linkage material taking and discharging mechanism and the polishing finished product placing rack can be arranged at intervals in a three-dimensional structure, for example, they can be arranged at the same vertical position, the heat pipe base pipe 11 is blocked by the blocker 3, the top surface of the material taking device 9 can also contact the heat pipe base pipe 11, and when the material taking device 9 continues to rise, the heat pipe can be taken off from the blocker 3. For example, the polishing mechanism is arranged at the position where the heat pipe base pipe 11 needs to be polished, and the linkage material taking and discharging mechanism can be arranged at other positions of the heat pipe base pipe 11.
