The pipe fitting clamp is composed of semi-circular clamp members arranged oppositely, and a rubber layer is provided on the inner side wall of the pipe fitting clamp to facilitate fixing the pipe fitting.

[0007] However, in the above method, since the cross tube of the frame has a hollow structure, during punching, the outer wall of the cross tube is subjected to radial forces, and there is no support structure inside the cross tube, resulting in its easy deformation. Summary of the Utility Model

[0008] The purpose of the utility model is to provide a cross tube punching device for the frame of an electric tricycle, aiming to solve the technical problem that in the prior art, since the cross tube of the frame is hollow, during punching, the outer wall of the cross tube is subjected to an inward force, and there is no support structure inside the cross tube, resulting in the easy deformation of the cross tube of the frame.

[0009] To achieve the above purpose, a cross tube punching device for the frame of an electric tricycle adopted by the utility model includes a support table, a bracket, a punching assembly, a bottom plate, a support mechanism, and two groups of clamping assemblies.

Place the metal part to be punched between the two clamping components, and clamp and fix the outer wall of the frame cross tube through the two clamping components. Then start the support cylinder, and the output end of the support cylinder drives the connecting block to move.

[0026] The present invention provides a cross-tube punching device for the frame of an electric tricycle, including a support platform 101, a bracket 102, a punching assembly 103, a bottom plate 104, a support mechanism and two clamping assemblies. The support mechanism includes a vertical plate 105, a slide plate 106, a support cylinder 107, a connecting block 108, two round rods 109, two load-bearing members 110, two right-angle plates 111 and two support plates 112. The adjusting assembly includes a fixed block 113, an adjusting block 114 and a screw 115. The clamping assembly includes a clamping cylinder 116 and a clamping block 117. The foregoing solution solves the technical problem in the prior art that since the cross-tube of the frame is hollow, when punching, the outer wall of the cross-tube of the frame is subjected to an inward force, and there is no support structure inside the cross-tube of the frame, resulting in the cross-tube of the frame being extremely prone to deformation.

[0027] For this specific implementation manner, the bracket 102 is fixedly connected to the support platform 101, the punching assembly 103 is arranged on the bracket 102, the bottom plate 104 is arranged on the support platform 101, the two clamping assemblies are used for clamping and fixing the cross-tube of the frame, and the bracket 102 is used for installing the punching assembly 103. The cross-tube of the frame is punched by the punching assembly 103.

[0028] Among them, the vertical plate 105 is fixedly connected to the bottom plate 104. The vertical plate 105 is provided with a first sliding groove 118. The sliding plate 106 is slidably connected to the first sliding groove 118. The sliding plate 106 is provided with two second sliding grooves 119.

The support cylinder 107 is installed on the sliding plate 106. The output end of the support cylinder 107 is fixedly connected to the connecting block 108. Two of the round rods 109 are respectively placed in the corresponding stress grooves 121. The two ends of the connecting block 108 are respectively fixedly connected to the corresponding round rods 109. Two of the right-angle plates 111 are respectively fixedly connected to the corresponding stress members 110. Two of the support plates 112 are respectively fixedly connected to the corresponding right-angle plates 111. The support plate 112 is provided with an avoidance groove 122. The sliding plate 106 is provided with an adjustment assembly for driving the sliding plate 106 to move. During specific use, the position of the sliding plate 106 is adjusted through the adjustment assembly, so as to adjust the positions of the two support plates 112 to a specified position, such that the center points of the two support plates 112 are located at the center points of the two clamping assemblies. The metal part to be punched is placed between the two clamping assemblies, and the outer wall of the cross tube of the vehicle frame is clamped and fixed by the two clamping assemblies. Subsequently, the support cylinder 107 is started. The output end of the support cylinder 107 drives the connecting block 108 to move. The connecting block 108 drives the two round rods 109 to slide in the corresponding stress grooves 121 respectively. While the two round rods 109 slide in the corresponding stress grooves 121, they can drive the two stress members 110 to move relative to each other. While the two stress members 110 move relative to each other, they drive the two support plates 112 to move relative to each other through the two right-angle plates 111 until the two support plates 112 abut against the inner wall of the cross tube of the vehicle frame for support. After that, the cross tube of the vehicle frame can be punched through the punching assembly 103. In this way, the inner wall of the cross tube of the vehicle frame can be supported, avoiding deformation of the cross tube of the vehicle frame during punching.

[0029] Secondly, the fixed block 113 is fixedly connected to the vertical plate 105. The adjusting block 114 is fixedly connected to the sliding plate 106. The screw 115 is rotatably connected to the fixed block 113, and the screw 115 is in threaded cooperation with the adjusting block 114. By rotating the screw 115, the screw 115 drives the adjusting block 114 to move, and the adjusting block 114 drives the sliding plate 106 to move, thereby adjusting the position of the support plate 112.

[0030] Meanwhile, the clamping cylinder 116 is installed on the bottom plate 104, and the output end of the clamping cylinder 116 is fixedly connected to the clamping block 117. The two clamping cylinders 116 drive the two clamping blocks 117 to move to clamp and fix the cross tube of the vehicle frame.

[0031] When using a cross tube punching device for an electric tricycle frame according to this embodiment, during specific use, the position of the sliding plate 106 is adjusted through the adjusting component, and then the two support plates 112 are adjusted to a specified position, so that the center points of the two support plates 112 are located at the center points of the two clamping components. The metal part to be punched is placed between the two clamping components, and the outer wall of the cross tube of the vehicle frame is clamped and fixed by the two clamping components. Subsequently, the support cylinder 107 is started, and the output end of the support cylinder 107 drives the connecting block 108 to move. The connecting block 108 drives the two round rods 109 to slide in the corresponding force receiving grooves 121 respectively. While the two round rods 109 slide in the corresponding force receiving grooves 121, they can drive the two force receiving parts 110 to move relatively. While the two force receiving parts 110 move relatively, they drive the two support plates 112 to move relatively through the two right angle plates 111 until the two support plates 112 abut against the inner wall of the cross tube of the vehicle frame for support. Then, the cross tube of the vehicle frame can be punched through the punching component 103. In this way, the inner wall of the cross tube of the vehicle frame can be supported, avoiding deformation of the cross tube of the vehicle frame during punching.
