Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle frame equipment, and particularly to a manufacturing device for an electric vehicle frame. Background Art

[0002] In the field of manufacturing electric vehicle frames, we have innovatively adopted the technology of arranging wire harnesses through the frame pipes. This design not only provides a strong physical barrier for the wire harnesses, effectively resisting potential damage from external factors such as flying stones and moisture, but also gives the vehicle a clear and tidy appearance.

[0003] However, despite the many significant advantages brought by this technology, we have also encountered quite a few challenges in actual operation. Especially the relatively large angle in the design of the frame turning point has become a "difficulty" for the wire harness to pass through. Due to the angle limitation, it is often difficult for the wire harness to smoothly pass from one end to the other. The wire harness can only be pushed to the turning point, and the worker has to wait patiently for the wire harness to completely pass through before pulling it. This process not only takes a long time but also directly affects the overall production efficiency. Therefore, we propose a manufacturing device for an electric vehicle frame. Summary of the Invention

[0004] (1) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the present invention provides a manufacturing device for an electric vehicle frame, which overcomes the deficiencies of the prior art, is reasonably designed, has a compact structure, and solves the problems raised in the background art.

[0006] (2) Technical Solutions

[0007] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0008] A manufacturing device for an electric vehicle frame includes a frame body, a control unit arranged on the frame body, and a driving unit rotatably arranged. The driving unit is rotatably arranged on the frame body and includes a cylinder body and a driving disk connected concentrically. The side wall of the cylinder body is provided with a chute for periodic advancement and retraction, and the end face of the driving disk is provided with a groove for periodic advancement and retraction. The control unit includes a fixed frame, a telescopic rod and a rotating rod connected by a connecting plate. The tail of the telescopic rod is connected with an extension rod extending into the chute, and the head of the rotating rod is provided with a notch for clamping and forking the wire harness.

[0009] Preferably, the chute includes an inclined chute inclined along the axial direction of the cylinder body and a vertical chute connected end to end with the inclined chute. The groove includes a first arc chute close to the main shaft and a second arc chute far from the main shaft. The openings of the two arc chutes face each other and are smoothly transitioned.

[0010] Preferably, a shaft sleeve is sleeved on the rotating rod, and the tail end of the shaft sleeve is connected with a control rod, and the control rod extends into the groove of the driving disk.

[0011] Preferably, a slide rail is provided on the outer wall of the rotating rod. The telescopic rod is fixedly connected to the rotating rod through a connecting plate. The slide rail is slidably matched with the fixed frame to limit the axial movement of the rotating rod.

[0012] Preferably, a contact rod is sleeved on the rotating rod. An axial groove is provided inside the contact rod. The protrusion on the rotating rod is matched with the groove to limit the rotation of the contact rod. One end of the contact rod is connected to the connecting plate through a spring, and the other end is provided with an elastic end. The elastic end is provided with an empty groove for providing a buffer space and preventing the wire harness from shaking when the wire harness is pulled.

[0013] Preferably, the elastic end is made of an elastic material. When the rotating rod extends into the turning part of the vehicle frame pipeline, the elastic end abuts against the wire harness to stabilize the position, and releases the wire harness into the empty groove following the movement when the rotating rod rotates.

[0014] Preferably, the driving unit is driven by an output motor. The inclined groove and the vertical groove of the sliding groove form a continuous closed track, and the periodic forward and backward movement of the rotating rod is realized through the reciprocating movement of the extension rod.

[0015] Preferably, a slide rail is provided between the telescopic rod and the fixed frame to limit the lateral sliding of the telescopic rod and avoid rotational deviation.

[0016] Preferably, the arc radius of the groove of the driving disc matches the rotation angle of the rotating rod to ensure smooth pulling of the wire harness after winding and avoid jamming.

Specific embodiments

[0028] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0029] Referring to the attached Figures 1-7 , an electric vehicle frame manufacturing device includes a frame body 1 and a drive unit 2 rotatably arranged on the frame body 1, and the drive unit 2 is driven to rotate by an output motor. A control unit 3 is also installed on the frame body 1. The control unit 3 is located on one side of the drive unit 2 and cooperates with the drive unit 2;

[0030] The drive unit 2 includes a cylinder body 21, a drive disk 22, and a main shaft 25. The cylinder body 21 and the drive disk 22 are concentrically arranged and fixedly connected to each other. The main shaft 25 is connected to the axis of the cylinder body 21 and the drive disk 22 and connected to the frame body 1, forming the drive unit 2 rotating on the frame body 1;

[0031] A chute 23 is opened on the upper side wall of the cylinder body 21. The chute 23 includes an inclined slot arranged along the axial direction of the cylinder body 21 and a parallel vertical slot. The inclined slot and the vertical slot are sequentially connected end to end to cover the side wall of the cylinder body 21;

[0032] A groove 24 is opened on the end face of the drive disk 22. The groove 24 includes an arc-shaped slot close to the main shaft 25 and an arc-shaped slot far from the main shaft 25. The openings of the two arc-shaped slots are arranged opposite to each other and connected, and the connection is smoothly transitioned.

[0033] The control unit 3 includes a fixing bracket 31. An expansion rod 32 and a rotating rod 35 are horizontally penetrated through the fixing bracket 31 in parallel. A notch for clamping the fork wiring harness is formed at the head of the rotating rod 35. An extension rod 33 connected to the tail of the expansion rod 32 extends into the sliding groove 23. When the driving unit 2 rotates, it drives the sliding groove 23 to rotate, so that the movement track of the extension rod 33 in the sliding groove 23 can be controlled. When the extension rod 33 slides to the inclined groove, since the expansion rod 32 can slide horizontally on the fixing bracket 31, the expansion rod 32 can be pushed to slide. A connecting plate 34 is fixedly sleeved on the expansion rod 32 and the slide rail 36, and the connecting plate 34 and the rotating rod 35 can be synchronously driven to slide on the fixing bracket 31;

[0034] To prevent the expansion rod 32 from rotating during sliding, a slide rail 36 is provided on the outer wall of the expansion rod 32. To facilitate controlling the rotation of the rotating rod 35, a sleeve 37 is sleeved on the rotating rod 35, and a slide rail 36 is provided on the outer wall of the rotating rod 35, so that the rotating rod 35 can not only slide horizontally under the action of the expansion rod 32, but also the rotation of the rotating rod 35 can be controlled by the sleeve 37;

[0035] Further, a control rod 38 is connected to the tail end of the sleeve 37, and the control rod 38 extends into the groove 24 on the driving disc 22. In the initial state, the control rod 38 is located in the arc groove far from the main shaft 25, and the extension rod 33 is located in the vertical groove far from the driving disc 22. When the driving unit 2 rotates, the extension rod 33 enters the inclined groove of 2, so that the expansion rod 32 and the rotating rod 35 extend forward into the pipe of the electric vehicle frame. The notch on the rotating rod 35 can be inserted into the wiring harness in the frame pipe. From the arc groove far from the main shaft 25 to the arc groove close to the main shaft 25, that is, controlling the deflection of the control rod 38, so that the wiring harness is wound around the rotating rod 35. Continuing to rotate the driving unit 2, the rotating rod 35 retracts and resets. During this process, the other end of the wiring harness simultaneously pushes the wire into the frame pipe, realizing the pulling of the wiring harness head against the turning point, and improving the overall inspection efficiency.

[0036] Further, when the rotating rod 35 extends into the turning part of the vehicle frame for fork clamping, since there will be redundant pushing when the wire harness is pushed towards the vehicle frame pipeline, the wire harness will shake. We sleeved a contact rod 4 on the rotating rod 35. A groove 44 is axially opened inside the contact rod 4. Axial protrusions are provided on the rotating rod 35 and cooperate with the groove 44 to prevent the contact rod 4 from rotating randomly on the rotating rod 35. A spring 41 is also provided between one end of the contact rod 4 and the connecting plate 34, and the other end is connected to an elastic end 42. An empty groove 43 opened on the elastic end 42 is used to provide some space for the wire harness during pulling. When the wire harness abuts against the turning part of the vehicle frame pipeline, the rotating rod 35 drives the contact rod 4 to move forward, and the elastic end 42 abuts against the wire harness to prevent the wire harness from shaking. The rotating rod 35 continues to move forward until the wire harness is fork-clamped. When the rotating rod 35 rotates, it will drive the elastic end 42 to rotate together. When the notch of the rotating rod 35 completes the fork-clamping rotation, at this time the wire harness will be at the empty groove 43, providing space for the wire harness and facilitating pulling. During pulling, the contact rod 4 will not retract immediately, and the wire harness will follow the rotating rod 35 into the tube of the contact rod 4 to protect part of the wire harness. Moreover, since the elastic end 42 is made of an elastic material, it will provide a certain safety guarantee for the wire harness. And because there will be a certain amount of redundant pushing of the wire harness in the pipeline of the vehicle frame, there will be interference of the wire harness in the pipeline during the initial pulling. The existence of the elastic end 42 will avoid such phenomena even during the initial pulling and protect the wire harness from rubbing against the bending part.
