Description

Technical Field

[0001] The utility model relates to a motorcycle rack welding tool. Background Art

[0002] The motorcycle rack is a key accessory on the motorcycle. As an existing motorcycle rack, please refer to Figure 1-3 It has a roughly U-shaped elbow N-1, two longitudinal reinforcement tubes N-2, a transverse reinforcement tube N-3 and four connecting plates N-4. The two ends of the transverse reinforcement tube N-3 are respectively welded and fixed to the rear of the two side pipe sections N-11 of the elbow N-1; and the two ends of each longitudinal reinforcement tube N-2 are respectively welded and fixed to the transverse reinforcement tube N-3 and the two bottom pipe sections N-12 of the elbow N-1; the two longitudinal reinforcement tubes N-2 are parallel and symmetrically distributed; the four connecting plates N-4 are respectively welded and fixed to the front of the two side pipe sections N-11 of the elbow N-1 and are symmetrically distributed. The motorcycle rack plays a load-bearing role and has extremely high requirements for safety strength. Therefore, during welding production, the elbow N-1, the two longitudinal reinforcement tubes N-2, the transverse reinforcement tube N-3 and the four connecting plates N-4 are required to be accurately welded to ensure the reliability of the overall strength after welding.

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0020] Example: See Figure 3-6 A motorcycle rack welding tool comprises a base 1, on which a pipe group positioning and clamping mechanism 2, four connecting plate positioning and clamping mechanisms 3 and two end hole positioning mechanisms 4 are arranged.

[0021] Among them, the pipe group positioning and clamping mechanism 2 includes a first positioning platform 2-1, two second positioning platforms 2-2, a cross-shaped pressure plate 2-3 and a clamping cylinder 2-4; the first positioning platform 2-1 is provided with two bend pipe positioning grooves 2-11 for positioning the two side pipe sections N-11 of the bend pipe N-1 and two longitudinal reinforcement pipe positioning grooves 2-11 for positioning the two longitudinal reinforcement pipes N-2; the two second positioning platforms 2-2 are spaced apart and are both provided with transverse reinforcement pipe positioning grooves 2-21 for positioning the transverse reinforcement pipe N-3; the cross-shaped pressure plate 2-3 is located above the first positioning platform 2-1 and is driven by the clamping cylinder 2-4 to move up and down; when the clamping cylinder 2-4 drives the cross-shaped pressure plate 2-3 downward, the cross-shaped pressure plate 2-3 will simultaneously clamp the two side pipe sections N-11 of the bend pipe N-1, the two longitudinal reinforcement pipes N-2 and the transverse reinforcement pipe N-3.

[0022] Specifically, the first positioning platform 2-1 and the two second positioning platforms 2-2 are welded or detachably fixed on the base 1. The cross-shaped pressing plate 2-3 is located directly above the first positioning platform 2-1 and the two second positioning platforms 2-2.

[0023] See also Figure 4 In this embodiment, the clamping cylinder 2-4 is located below the first positioning platform 2-1; two guide rods 2-5 are movably installed on the first positioning platform 2-1; the upper ends of the two guide rods 2-5 are fixedly connected to the cross-shaped pressure plate 2-3; the lower ends of the two guide rods 2-5 are fixedly connected to the output end of the clamping cylinder 2-4 through the driving plate 2-6. Specifically, the clamping cylinder 2-4 is vertically fixedly installed on the base 1 and is located below the first positioning platform 2-1. The output end of the clamping cylinder 2-4 is fixedly connected to the middle of the driving plate 2-6; the lower ends of the two guide rods 2-5 are fixedly connected to the two ends of the driving plate 2-6 respectively.

[0024] In this embodiment, the clamping cylinders 2 - 4 are telescopic cylinders.

[0025] See also Figure 4 When pressing, the output end of the pressing cylinder 2-4 retracts downward, and the pressing cylinder 2-4 drives the driving plate 2-6 downward, and the driving plate 2-6 drives the two guide rods 2-5 downward at the same time, and the two guide rods 2-5 pull the cross-shaped pressing plate 2-3 downward, thereby pressing the two side pipe sections N-11, the two longitudinal reinforcement pipes N-2 and the transverse reinforcement pipe N-3 (see Figure 7-9 ). When releasing after welding, the output end of the clamping cylinder 2-4 extends upward, and the clamping cylinder 2-4 drives the driving plate 2-6 upward, and the driving plate 2-6 drives the two guide rods 2-5 upward at the same time, and the two guide rods 2-5 pull the cross-shaped clamping plate 2-3 upward, thereby loosening and moving away from the two side pipe sections N-11, the two longitudinal reinforcement pipes N-2 and the transverse reinforcement pipe N-3 of the bent pipe N-1 below. Then, it is convenient to take out the motorcycle rack (see Figure 12-14 ).

[0026] The four connection plate positioning and clamping mechanisms 3 each include a support platform 3-1 and a corner cylinder 3-2; a positioning pin 3-11 is fixedly arranged on the top surface of the support platform 3-1. Specifically, the support platform 3-1 is used for the positioning pin 3-11 to support and position the connection plate N-4, and the positioning pin 3-11 is used for the connection hole N-41 of the connection plate N-4 to cooperate with the positioning, so as to ensure that the connection hole N-41 of the connection plate N-4 is accurately positioned after welding (see Fig.10 ).

[0027] In this embodiment, the corner cylinder 3-2 adopts a pneumatic corner cylinder. The specific structure of the corner cylinder 3-2 belongs to the existing technology and can be directly purchased and assembled, so it is not repeated. When clamping, the pressing arm of the corner cylinder first rotates to the top of the workpiece, and then moves vertically downward to press the workpiece; when loosening, the pressing arm of the corner cylinder automatically returns to the original position along the clamping route to clear the workpiece, so that the operator can smoothly and conveniently remove the workpiece.

[0028] The two end hole positioning mechanisms 4 each include a vertical plate 4-1 and a plug 4-2; the vertical plate 4-1 is provided with a plug hole 4-11; the plug 4-2 and the plug hole 4-11 can be slidably matched. When positioning, the plug 4-2 is inserted into the plug hole 4-11 and then pressed internally, so that the plug 4-2 is inserted into the end hole of the elbow N-1 to achieve positioning (see Fig.10 ); when releasing, the latch 4-2 is pulled outwardly so that the latch 4-2 exits the end hole of the elbow N-1 to achieve release.

[0029] Furthermore, a handle 4-21 is provided on the latch 4-2, which facilitates operation and saves time and effort.

[0030] When the motorcycle rack welding tool of this embodiment is used for welding a motorcycle rack, the operation steps may be as follows:

[0031] S10, insert the two side pipe sections N-11 of the elbow N-1 into the two elbow positioning grooves 2-11 on the first positioning platform 2-1 respectively; then insert the two latches 4-2 into the insertion holes 4-11 of the two vertical plates 4-1 respectively, and then press and slide them into the two end holes N-13 of the elbow N-1 respectively, at this time, the elbow N-1 is completely positioned (see Figure 7-11 );

[0032] S20, insert the two longitudinal reinforcing tubes N-2 into the two longitudinal reinforcing tube positioning grooves 2-11 on the first positioning platform 2-1 for positioning; insert the transverse reinforcing tube N-3 into the transverse reinforcing tube positioning grooves 2-21 on the two second positioning platforms 2-2 arranged at intervals for positioning (see Figure 7-11 );

[0033] S30, start the clamping cylinder 2-4 to work and drive the cross-shaped pressing plate 2-3 downward, so that the cross-shaped pressing plate 2-3 simultaneously presses the two side pipe sections N-11 of the bent pipe N-1, the two longitudinal reinforcement pipes N-2 and the transverse reinforcement pipe N-3 (see Figure 7-11 );

[0034] S40, place the four connecting plates N-4 on the top surfaces of the support platforms 3-1 of the four connecting plate positioning and clamping mechanisms 3, respectively, so that the connecting holes N-41 of the four connecting plates N-4 are respectively matched with the positioning pins 3-11 on the four supporting platforms 3-1 for positioning; then start the four corner cylinders 3-2 of the four connecting plate positioning and clamping mechanisms 3 to work, so that the four corner cylinders 3-2 respectively clamp the four connecting plates N-4 (see Figure 7-11 );

[0035] S50, welding is performed to obtain a motorcycle rack product: the welding robot can be used to control the welding gun for automatic welding, or the welding gun can be manually operated for welding;

[0036] S60, start the corner cylinders 3-2 of the four connection plate positioning and clamping mechanisms 3 to work, so that the four corner cylinders 3-2 loosen the four connection plates N-4 respectively; start the clamping cylinder 2-4 to work and drive the cross-shaped pressing plate 2-3 upward to simultaneously loosen the two side pipe sections N-11, the two longitudinal reinforcement pipes N-2 and the transverse reinforcement pipe N-3 of the bent pipe N-1; then pull the two latches 4-2 outward to make the two latches 4-2 withdraw from the two end holes of the bent pipe N-1 respectively to achieve loosening without obstruction; then the welded motorcycle rack can be directly taken out (see Figure 12-14 ).

[0037] Therefore, the utility model adopts a tooling structure design different from the existing one, which can be used for the above-mentioned motorcycle rack to accurately position and press its components during welding, thereby ensuring welding accuracy; at the same time, it has the advantages of reliable clamping, simple operation, and convenient loading and unloading.

[0038] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
