Description

Technical Field

[0001] The utility model belongs to the field of aluminum pipe processing, and particularly relates to a square aluminum pipe grinding device. Background Art

[0002] In the field of new energy vehicle technology, electric vehicles generally use a power battery pack as a power source. Different from a fuel engine, an electric vehicle itself does not have a power device that generates heat, and thus cannot provide heat to the power battery pack. At the same time, it also cannot provide the warm air heat source required for air conditioning, defrosting, etc. Therefore, an electric vehicle must rely on electric energy to heat by using a PTC heater.

[0003] A PTC heater usually uses a square aluminum pipe as an installation carrier for a PTC heating element. As a heater fitting, the square aluminum pipe has high quality requirements. After its processing is completed, generally, the square aluminum pipes with burrs on the surface are selected and ground by means of a grinding device.

[0004] However, during the grinding process of the aluminum pipe by the existing grinding device, it is impossible to ensure that the grinding block always adheres tightly to the surface of the aluminum pipe, which may lead to uneven grinding quality of the aluminum pipe. In addition, during the grinding process, the grinding block may vibrate slightly, affecting the stability during the grinding process. Summary of the Utility Model

[0005] In view of the above problems, the purpose of the utility model is to provide a square aluminum pipe grinding device, aiming to solve the problems of poor grinding quality and unstable grinding process of the existing square aluminum pipe grinding device.

[0006] The utility model adopts the following technical scheme: The square aluminum pipe grinding device includes a vertical movement module. A carrier is provided at the moving end of the vertical movement module. A hollow mounting block is provided on the side wall of the carrier. A driving gear and a rotating rod are rotatably provided inside the mounting block. A driven gear is provided at the top of the rotating rod, and the driving gear and the driven gear are meshed and installed. A connecting sleeve is slidably and limitedly provided at the bottom of the rotating rod. A connecting rod is provided at the bottom of the connecting sleeve. A grinding block is provided at the bottom of the connecting rod. A pre-tightening spring is provided on the rotating rod between the mounting block and the connecting sleeve. A shock absorption mechanism is provided on the carrier corresponding to the rotating rod. A grinding motor for driving the driving gear to rotate is provided at the top of the carrier.

[0007] Further, the shock absorption mechanism includes a pair of sliding sleeves installed at the bottom of the carrier. A sliding rod is inserted into the sliding sleeves. A bottom block is jointly provided at the bottom of the sliding rods. The connecting rod passes through the bottom block and then the grinding block is provided.

[0008] Further, an elastic member is provided between the carrier and the bottom block.

[0009] Further, a through short groove is formed in the side wall of the connecting sleeve, a limiting screw is inserted from one side of the short groove, and after the limiting screw is screwed into the rotating rod, it passes out from the other side of the short groove.

[0010] Further, a top plate is jointly arranged at the tops of the two sliding rods.

[0011] The beneficial effects of the present utility model are as follows: After the square aluminum tube is fixed, the vertical moving module drives the carrier to move downward. At this time, the grinding block moves toward the square aluminum tube until the grinding block contacts the square aluminum tube. The carrier continues to move downward a short distance. At this time, the pre-tightening spring gradually contracts. Under the pre-tightening action of the pre-tightening spring, the grinding block tightly adheres to the square aluminum tube. Then, the transverse moving module drives the entire grinding device to slide horizontally along the length direction of the square aluminum tube. During the sliding process, the grinding motor drives the rotating rod to rotate, and the grinding block rotates synchronously to grind the corresponding surface of the square aluminum tube.

[0016] In order to make the patent purpose, technical solution and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0017] In order to illustrate the technical solution described in the present utility model, the following is illustrated by specific embodiments.

[0018] For the convenience of description, only parts related to the embodiments of the present utility model are shown.

[0019] Combined with Figures 1-4As shown in the figure, the square aluminum tube grinding device includes a vertical movement module 1. A carrier 2 is provided at the moving end of the vertical movement module 1. A hollow mounting block 3 is provided on the side wall of the carrier 2. An active gear 4 and a rotating rod 5 are rotatably provided in the mounting block 3. A driven gear 6 is provided at the top of the rotating rod 5, and the active gear 4 and the driven gear 6 are meshed and installed. A connecting sleeve 8 is slidably and limitedly provided at the bottom of the rotating rod 5. A connecting rod 9 is provided at the bottom of the connecting sleeve 8. A grinding block 10 is provided at the bottom of the connecting rod 9. A pre-tightening spring 11 is provided between the mounting block 3 and the connecting sleeve 8 on the rotating rod 5. A damping mechanism is provided on the carrier 2 corresponding to the rotating rod 5. A grinding motor 7 for driving the active gear to rotate is provided at the top of the carrier 2.

[0020] PTC heaters usually use square aluminum tubes as the installation carriers for PTC heating elements. As a heater accessory, the quality requirements for square aluminum tubes are relatively high. If a small amount of burrs are found on the surface of the square aluminum tube after production, this grinding device can be used for grinding.

[0021] And this vertical movement module is installed on the moving end of the horizontal movement module. When grinding the square aluminum tube, first install the two ends of the square aluminum tube on the positioning fixture. The vertical movement module drives the carrier to move downward. At this time, the grinding block moves towards the square aluminum tube until the grinding block contacts the square aluminum tube. The carrier continues to move downward a short distance. At this time, the pre-tightening spring gradually contracts. Under the pre-tightening action of the pre-tightening spring, the grinding block tightly adheres to the square aluminum tube. Immediately afterwards, the horizontal movement module drives the entire grinding device to slide horizontally along the length direction of the square aluminum tube. During the sliding process, the grinding motor drives the rotating rod to rotate, and the grinding block rotates synchronously to grind the corresponding surface of the square aluminum tube. After grinding, the square aluminum tube can be rotated to grind the other surface of the square aluminum tube.

[0022] During the grinding process, under the pre-tightening action of the pre-tightening spring, the grinding block can always maintain a state of tightly adhering to the surface of the square aluminum tube, thereby improving the grinding quality of the square aluminum tube.

[0023] As a preferred structure, as Figure 3 , a through short groove 12 is opened on the side wall of the connecting sleeve 8. A limit screw 13 is inserted from one side of the short groove 12. After the limit screw 13 is screwed into the rotating rod 5, it passes through the other side of the short groove.

[0024] In this structure, the connecting sleeve is slidably and limitedly installed on the rotating rod through the limit screw. A short groove is opened on the connecting sleeve. Inserting the limit screw into the short groove can limit the up and down sliding distance of the connecting sleeve. At the same time, under the action of the limit screw, the rotating rod can drive the connecting sleeve to rotate, and the grinding block can thus rotate normally.

[0025] The above-mentioned horizontal movement module can drive the whole device to move along the length direction of the square aluminum tube, so as to change the grinding position of the square aluminum tube. The horizontal movement module can drive the carrier to move vertically. Both the above-mentioned horizontal movement module and the horizontal movement module are prior arts. As a preferred structure, they can both include a moving frame 114. A lead screw (blocked in the figure) is rotatably arranged in the moving frame. A lead screw sleeve is sleeved on the lead screw. A connecting plate is arranged on the lead screw sleeve. The connecting plate is the moving end. And a driving motor 115 for driving the lead screw to rotate is further arranged on the moving frame.

[0026] Such as Figures 3-4 , the shock absorption mechanism includes a pair of sliding sleeves 14 installed at the bottom of the carrier. A sliding rod 15 is inserted into the sliding sleeve 14. A bottom block 16 is jointly arranged at the bottom of the sliding rod 15. After the connecting rod 9 passes through the bottom block 16, the grinding motor 10 is arranged.

[0027] When grinding the square aluminum tube, the grinding block tightly adheres to the square aluminum tube and contacts the bottom block. During the grinding process, the grinding block will slightly jump up and down, thereby driving the bottom plate to slightly jump up and down. When the bottom plate slightly jumps up and down, at this time, the sliding rod will slide in the corresponding sliding sleeve. At this time, the bottom plate plays a guiding role for the grinding block.

[0028] An elastic member 17 is arranged between the carrier 2 and the bottom block 16. The elastic member can be a spring.

[0029] When the bottom plate slightly jumps up and down, at this time, the bottom plate will squeeze the elastic member. Under the action of the elastic member, the amplitude of the up and down jump of the bottom plate can be reduced. Thus, the shock absorption effect on the grinding block is achieved, and further the quality of grinding the square aluminum tube by the grinding block is improved.

[0030] In addition, a top plate 18 is jointly arranged at the tops of the two sliding rods 15. Under the action of the top plate, the sliding rods can move up and down synchronously, so that the bottom plate can move stably.

[0031] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
