[0025] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figure 1 As shown, the utility model provides an assembly mechanism of a flat fork leg tube assembly machine, including an assembly platform 1, and the small tube 3 is assembled in one end of a large tube 2 by using the assembly platform 1, so that the strength of one end of the large tube 2 is greatly improved.

[0027] As an example, Figure 1 The upper surface of the assembly platform 1 includes a large tube placement area 110, a fixing component 120, a small tube placement area 130 and a driving component 140. The small tube placement area 130 is located at the left end of the assembly platform 1, and the small tube placement area 130 is used to place the small tube 3; the large tube placement area 110 is located at the right end of the assembly platform 1, and the large tube placement area 110 is used to place the large tube 2; the fixing component 120 is located on the large tube placement area 110, and is used to fix the large tube 2 on the large tube placement area 110; the driving component 140 is used to push the small tube 3 on the small tube placement area 130 into the large tube 2 on the large tube placement area 110 so that the strength of the large tube 2 is improved.

[0028] like Figure 2, the fixing component 120 includes a fixing frame 121, a fixing block 122 and a fixing cylinder 123. The fixing frame 121 is located in the large pipe placement area 110. The fixing frame 121 is in a "C" - shaped structure with an opening downward. The lower ends of the fixing frame 121 are respectively fixed on the upper surface of the large pipe placement area 110. The fixing frame 121 is arranged along the length direction of the large pipe placement area 110. The large pipe 2 is located directly below the fixing frame 121; the fixing block 122 is located directly above the large pipe 2, and both ends of the large pipe 2 are respectively abutted against the inner side walls of the fixing frame 121 to achieve axial positioning of the large pipe 2; the fixing cylinder 123 is arranged on the upper surface of the fixing frame 121. The lower end of the piston rod of the fixing cylinder 123 is connected to the fixing block 122. The fixing cylinder 123 drives the fixing block 122 to descend and press on the large pipe 2 to achieve radial positioning and circumferential positioning of the large pipe 3. Axial positioning of the large pipe 2 is achieved through the fixing frame 121, and at the same time, the fixing cylinder 123 is used to drive the fixing block 122 to achieve radial and circumferential positioning of the large pipe 2, so that the large pipe 2 can be fixed, facilitating the insertion of the small pipe 3 into one end of the large pipe 2. Specifically, an arc - shaped groove matching the outer surface of the large pipe 2 is provided on the bottom surface of the fixing block 122. When the fixing block 122 presses on the large pipe 2, the inner side wall of the arc - shaped groove fits on the outer side surface of the large pipe 2.

[0029] As an embodiment, a guiding hole 1211 is provided on the outer side surface of the lower end of the fixing frame 121 near the small pipe placement area 130. The small pipe 3 is in sliding fit with the guiding hole 1211. The small pipe 3 passes through the guiding hole 1211 and is inserted into the large pipe 2. At this time, the axis of the large pipe 2 and the axis of the guiding hole 1211 are on the same horizontal line. The guiding hole 1211 plays a guiding role for the small pipe 3.

[0030] As an embodiment, in order to ensure that the large tube 2 is accurately positioned below the fixing frame 121, a large tube positioning block 111 is further provided on the upper surface of the large tube placement area 110. The large tube positioning block 111 is located below the fixing frame 121 and is distributed along the length direction of the fixing frame 121. The large tube 2 abuts against the rear side of the large tube positioning block 111 to achieve positioning of the large tube 2. Specifically, in order to improve the safety factor, it also includes a large tube pushing cylinder 112. The large tube pushing cylinder 112 is located behind the large tube placement area 110 corresponding to the assembly platform 1. The large tube 2 is horizontally placed at the rear end of the upper surface of the large tube placement area 110. The piston rod of the large tube pushing cylinder 112 pushes the large tube 2 toward the rear side of the large tube positioning block 111, so that the large tube 2 abuts against the rear side of the large tube positioning block 111 to achieve positioning of the large tube 2. In this way, there is no need to place the large tube 2 on the rear side of the large tube positioning block 111 by hand, and the fixing block 122 will not press the hand, which has a high safety factor. Specifically, it also includes a push plate 113 for pushing the large tube 2. The push plate 113 is located at the rear end of the upper surface of the large tube placement area 110 and is arranged along the length direction of the assembly platform 1. The piston rod of the large tube pushing cylinder 112 is connected to the push plate 113. The large tube pushing cylinder 112 pushes the push plate 113 toward the fixed frame 121, thereby pushing the large tube 2 toward the rear side of the large tube positioning block 111.

[0031] As an embodiment, in order to prevent the large tube positioning block 111 from affecting the fixing block 122 from pressing on the large tube 2, the height of the large tube positioning block 111 is smaller than the diameter of the large tube 2. Specifically, the height of the large tube positioning block 111 is smaller than the radius of the large tube 2, so that when the fixing block 122 is pressed on the large tube 2, the cross-section of the arc-shaped groove on the fixing block 122 is generally semicircular, and the fixing block 122 is stuck on the upper half of the large tube 2, and the fixing block 122 will not touch the large tube positioning block 111, and the reliability is high.

[0032] As an embodiment, it also includes a driving member 140, which is used to insert the small tube 3 on the small tube placement area 130 into the large tube 2. At this time, the large tube 2 is fixed at the front end of the large tube placement area 110. The driving member 140 can be a cylinder or a gas cylinder. Specifically, it also includes a small tube positioning block 131 for positioning the small tube 3. The small tube positioning block 131 is located on the upper surface of the small tube placement area 130. The small tube 3 is attached to the rear side of the small tube positioning block 131. At this time, the axis of the small tube 3 and the axis of the large tube 2 are in the same straight line. The piston rod of the driving member 140 inserts the small tube 3 into the large tube 2. Specifically, in order to improve the safety factor, it also includes a small tube pushing cylinder 132, which is located at the rear side of the assembly platform 1 corresponding to the small tube placement area 130. The small tube pushing cylinder 132 pushes the small tube 3 toward the rear side of the small tube positioning block 131, so that the small tube 3 abuts against the rear side of the small tube positioning block 131 to achieve positioning of the small tube 3, so that the axis of the small tube 3 and the axis of the large tube 2 are in the same straight line, which facilitates the small tube 3 to be aligned with the large tube 2 and inserted into the left end of the large tube 2. Specifically, in order to prevent the small tube 3 from crossing the small tube positioning block 131 during the process of pushing the small tube 3, the small tube positioning block 131 is greater than or equal to the diameter of the small tube 3, so that the small tube 3 will not deviate from the position when inserted into the large tube 2, and the reliability is high.

[0033] Specifically, three baffles are provided on the upper surface of the assembly platform 1. The baffles are arranged along the width direction of the assembly platform 1. The baffles are respectively located on the left side, the middle and the right side of the assembly platform 1, and are used to divide the upper surface of the assembly platform 1 into a large tube placement area 110 and a small tube placement area 130. Two adjacent baffles are respectively used to limit the axis of the large tube 2 and the small tube 3, ensuring that the large tube 2 and the small tube 3 are arranged on the assembly platform 1 along the length direction of the assembly platform 1.

[0034] Specifically, Figure 1 A small tube conveyor belt is provided at the rear of the left side of the assembly platform 1, which is used to transport the small tube 3 to the rear of the small tube placement area 130, and then push it to the small tube placement area 130 by the small tube pushing cylinder 132; a large tube conveyor belt is provided at the rear of the right side of the assembly platform 1, which is used to transport the large tube 2 to the rear of the large tube placement area 110, and then push it to the large tube placement area 110 by the large tube pushing cylinder 112.

[0035] Specifically, Figure 3The flat fork leg tube assembly machine includes a small tube conveying mechanism, an assembly platform 1, a large tube conveying mechanism, a tube cutting mechanism, a feeding mechanism, and a loading mechanism which are arranged in sequence from left to right. The small tube conveying mechanism is used to convey the small tube 3 to the assembly platform 1; the loading mechanism is used to convey the large tube 2 to the feeding mechanism, and the feeding mechanism is used to convey the large tube to the tube cutting mechanism 6 to cut into small sections of the large tube 2. When cutting, the left end of the large tube 2 is located on the large tube conveying mechanism, so that when the cutting of the large tube 2 is completed, the large tube conveying mechanism conveys the large tube 2 to the assembly platform 1; the small tube 3 is assembled in one end of the large tube 2 by using the assembly platform 1, so that the strength of one end of the large tube 2 is greatly improved.

[0036] Specifically, the principle of the utility model is to set up an assembly platform 1, which is divided into a large tube placement area 110 for placing a large tube 2 and a small tube placement area 130 for placing a small tube 3. At the same time, a fixing assembly 120 is set in the large tube placement area 110, and a driving member 140 is set in the small tube placement area 130; first, the large tube 2 is fixed in the large tube placement area 110 by using the fixing assembly 120, and then the driving member 140 is used to drive the small tube 3 to align with the large tube 2 and insert it into the left end of the large tube 2, so that the strength of the left end of the large tube 2 is strengthened. Using the driving member 140 and the fixing assembly 120 to replace manual labor is high in efficiency and low in labor intensity.

[0037] Action process: 1. Place the large tube 2 and the small tube 3 to the rear end of the large tube placement area 110 and the rear end of the small tube placement area 130 respectively; 2. Use the large tube pushing cylinder 112 to push the large tube 3 to the rear side of the large tube positioning block 111, so that the large tube 2 is located directly below the fixing frame 121 and the left and right ends of the large tube 2 are respectively against the two inner walls of the fixing frame 121; 3. Use the fixing cylinder 123 to drive the fixing block 122 to press on the large tube 2 to fix the large tube 2; 4. Use the small tube pushing cylinder 132 to push the small tube 3 to the rear side of the small tube positioning block 131, so that the small tube 3 is aligned with the large tube 2; 5. Use the driving member 140 to drive the small tube 3 to pass through the guide hole 1211 and insert it into the left end of the large tube 2 to realize the assembly of the large tube 2 and the small tube 3.
