[0034] Please refer to Figure 1 , Figure 3As shown, in one embodiment of the present invention, a motor 100 is disposed below the front and rear sliding platforms, and a motor reducer 101 is connected to the motor 100. A first synchronous pulley 102 and a product-shaped contouring tooling base plate 117 are connected to the motor reducer 101 via a drive shaft, allowing the motor reducer 101 to drive the first synchronous pulley 102 and the product-shaped contouring tooling base plate 117 to rotate synchronously. A second synchronous pulley 104 is disposed below a first tooling mounting base plate 125, and can be connected to the first tooling mounting base plate 125 via a drive shaft, allowing the second synchronous pulley 104 to drive the first tooling mounting base plate 125 to rotate synchronously.

Under the action of the motor 100, motor reduction gearbox 101, first synchronous pulley 102, synchronous belt 103 and second synchronous pulley 104, the product shape contouring tooling base plate 117 and the first tooling mounting base plate 125 are allowed to rotate synchronously.

[0035] Please see Figure 1 , Figure 4 As shown, in one embodiment of the present invention, a first tooling mounting base plate 125 is disposed on a base plate 114, and a height-contouring tooling 124 is disposed on the first tooling mounting base plate 125. The first tooling mounting base plate 125 adopts a cross-groove design, which allows for quick replacement and positioning of the height-contouring tooling 124.

[0036] Please see Figure 1 , Figure 2 , Figure 3As shown, in an embodiment of the present application, the front and rear sliding platform 116 is arranged on the base plate 125, and the front and rear sliding platform 116 has a track arranged on the base plate 125, allowing the front and rear sliding platform 116 to slide forward and backward on the track. The front and rear sliding compression spring 115 is connected with the front and rear sliding platform 116, and through the elastic force of the front and rear sliding compression spring 115, the front and rear sliding platform 116 can be kept in the initial position. The second tool mounting base plate 117 is arranged on the front and rear sliding platform 116, the product shape profiling tool 118 is arranged on the second tool mounting base plate 117, and the second tool mounting base plate 117 adopts a cross slot design, which can quickly replace and position the product shape profiling tool 118. The product positioning tool 119 is arranged on the product shape profiling tool 118, and the product to be tested 120 is arranged on the product shape profiling tool 118. The leaning wheel 105 is fixed on the base plate 114, and the leaning wheel 105 contacts the side of the product shape profiling tool 118. Since the second tool mounting base plate 117, the product shape profiling tool 118, the product positioning tool 119, and the product to be tested 120 are mechanically connected together, when the motor 100 drives the product shape profiling tool base plate 117 to rotate, the above components rotate synchronously. Since the product shape profiling tool 118 is not cylindrical, under the action of the front and rear sliding compression spring 115 and the leaning wheel 105, the front and rear sliding platform 116 slides on the track, ensuring that the contact point position of the product to be tested 120 with the belt sander 113 remains unchanged.

[0037] Please refer to Figure 1 、 Figure 4 、 Figure 6As shown, in one embodiment of the present invention, the height-adjustable linear slide rail 126 is fixed on the base plate 114, and the height-sliding platform 121 is disposed on the height-adjustable linear slide rail 126, allowing the height-sliding platform 121 to slide up and down on the track of the height-adjustable linear slide rail 126. The positioning height roller 123 is connected to the roller fixing block 122 via bearings, allowing the positioning height roller 123 to rotate itself and drive the roller fixing block 122 to move up and down. The roller fixing block 122 is mechanically connected to the height-sliding platform 121, allowing the roller fixing block 122 to drive the height-sliding platform 121 to slide up and down on the track of the height-adjustable linear slide rail 126. A slide rail is provided on one side of the height-sliding platform 121, and the belt sander lifting sliding platform 111 is connected to the height-sliding platform 121 via the slide rail on one side of the height-sliding platform 121, allowing the belt sander lifting sliding platform 111 to slide up and down relative to the height-sliding platform 121. A lifting limit rod 110 is installed on the lifting sliding platform 111 of the belt sander to limit the travel of the lifting sliding platform 111 on the track. A lifting cylinder 109 is installed on the lifting sliding platform 111 of the belt sander, allowing the lifting cylinder 109 to drive the lifting sliding platform 111 to slide on the height sliding platform 121, and allowing the lifting cylinder 109 to fix the relative position of the lifting sliding platform 111 and the height sliding platform 121, allowing the height sliding platform 121 to drive the lifting sliding platform 111 to slide synchronously.

[0038] Please see Figure 2 , Figure 5 As shown, in one embodiment of the present invention, the belt sander 113 is mechanically connected to the height-adjustable linear slide rail 126. The spring balancer 106 is installed on the height-adjustable linear slide rail 126 and connected to the height sliding platform 121 via a steel wire rope 107 and a pulley 108. Under the elastic force of the spring balancer 106, the weight of the sanding height sliding platform 121 and its connecting components can be controlled by adjusting the spring balancer 106, thereby controlling the sanding force of the belt sander 113 on the product 120 to be tested, for example, it can be 0.5-0.8KG.

[0039] Please see Figure 2 , Figure 5 As shown, in one embodiment of the present invention, the belt sander 113 is mechanically connected to the belt sander lifting sliding platform 111. A belt sander angle adjuster 112 is provided at the connection point, allowing adjustment of the sanding angle. For example, the angle between the belt sander 113 and the product 120 to be sanded can be 50 degrees. The belt track of the belt sander 113 is specially designed to be arc-shaped, allowing for a buffer distance at the belt-product contact point. For example, the buffer distance can be 5mm or 6mm, preventing over-sanding of the product and affecting product quality.

[0040] Please see Figure 1 ,Figure 2 , Figure 3 As shown, in one embodiment of the present invention, the equipment is started, and the belt sander lifting cylinder 109 drives the belt sander 113 to rise. The product shape contouring fixture 118 and the height contouring fixture 124 are manually installed on the second fixture mounting base plate 117 and the first fixture mounting base plate 125, respectively. The cross grooves on the second fixture mounting base plate 117 and the first fixture mounting base plate 125 are used for positioning and fixing. The product positioning fixture 119 is installed on the second fixture mounting base plate 117, and the product to be tested 120 is installed on the product positioning fixture 119. The belt sander lifting limit rod 110 and the belt sander lifting cylinder 109 are adjusted so that the belt sander 113's sanding belt contacts the product to be tested 120. Simultaneously, the belt sander angle adjuster 112 is adjusted so that the grinding angle meets the requirements; for example, the angle between the product to be tested 120 and the sanding belt can be 50 degrees. Since the opening curve of the high-profile tooling 124 is the same as the opening curve of the product under test 120, the position of the high-profile tooling 124 is manually adjusted so that the contact point between the high-profile tooling 124 and the high-profile roller 123 is equal to the contact point between the product under test 120 and the belt sander 113. The motor of the belt sander 113 is started, and the sanding belt of the belt sander 113 begins to rotate. At the same time, the motor 100 is started. Under the action of the motor 100, the motor reduction box 101, the first synchronous pulley 102, the synchronous belt 103, and the second synchronous pulley 104, the product outline contour tooling base plate 117 and the first tooling mounting base plate 125 begin to rotate synchronously. Since the product under test 120 is not cylindrical, under the action of the front and rear sliding pressure springs 115 and the guide rollers 105, the front and rear sliding platforms 116 slide on the track to ensure that the contact point position between the product under test 120 and the belt sander 113 remains unchanged. The rotation of the first fixture mounting base plate 125 drives the height contouring fixture 124 to rotate synchronously. Because the height roller 123 contacts the height contouring fixture 124, and the opening of the product to be tested 120 has an irregular curve, and the opening curve of the height contouring fixture 124 is the same as the opening curve of the product to be tested 120, the height sliding platform 121 can slide up and down on the height adjustment linear slide rail 126, driving the belt sander 113 to slide up and down synchronously, ensuring that the sanding belt of the belt sander 113 always maintains a good grinding distance and angle with the opening of the product to be tested 120. Driven by the motor 100, the sanding belt grinds along the product opening curve for a predetermined number of turns, completing the grinding work. The motor of the belt sander 113 stops rotating, and the belt sander 113 rises to a predetermined position under the action of the belt sander lifting cylinder 109. The motor 100 stops at the initial position, and the worker removes the ground product to be tested 120, completing the grinding work.

[0041] In summary, the automatic deburring and polishing machine for the curved opening of irregularly shaped thin tubes provided by this invention can conveniently and quickly polish the burrs on the curved opening of irregularly shaped thin tubes. Compared with traditional manual polishing, it improves polishing efficiency and reduces the labor intensity of workers while ensuring polishing quality.
