Description

Technical Field

[0001] The invention belongs to the technical field of motorcycle production equipment, and in particular relates to a beach vehicle frame bending device. Background Art

[0002] All-terrain vehicles are vehicles that can travel on any terrain and can move freely on terrain that is difficult for ordinary vehicles to maneuver. In China, they are commonly known as beach cars. Because their structure is very similar to that of motorcycles and many of their parts are common to motorcycles, some people also call them "four-wheeled motorcycles." This type of vehicle has multiple uses and is not restricted by road conditions. Its sales volume is increasing year by year.

[0003] The frame of a beach car is its skeleton and supporting structure, and is an important structural part of the beach car. It is usually made of steel or aluminum alloy to ensure sufficient strength and rigidity while keeping the vehicle lightweight. In order to ensure the overall strength of the beach car frame, the main body of the beach car frame is usually bent from tubular metal. The bending of metal tubes usually uses a pipe bending machine, which is usually divided into fully automatic, semi-automatic and manual. The fully automatic pipe bending machine can achieve fully automatic pipe bending through a preset program, but the fully automatic pipe bending machine is expensive. The semi-automatic pipe bending machine requires the operator to manually adjust the length and bending direction of the bent pipe. Although the manual pipe bending machine is cheap, the production efficiency is too low. The frame of the beach car needs to be bent many times in different planes. The fully automatic pipe bending machine can well meet the bending requirements of the beach car frame, but the length, angle and other parameters of the beach car frame of the same model are the same. The fully automatic pipe bending machine only needs to preset the program once for continuous production, which is completely over-performance for production enterprises. The use of fully automatic pipe bending machines has virtually increased the production costs of enterprises. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a beach vehicle frame bending device. Based on a semi-automatic pipe bending machine, the present invention automatically controls the length of the beach vehicle frame that needs to be bent, ensures the quality stability of the frames in the same batch, effectively improves production efficiency and reduces production costs.

[0010] Through the above technical scheme, the metal tube is installed on the clamp mechanism, and the front end of the metal tube passes between the bending mechanism and the guide wheel.

[0012] Through the above technical scheme, since a limit plate is fixedly connected to one side of the clamp mechanism, and a slide plate is fixedly connected to the other side of the clamp mechanism, the limit plate is slidably connected to the limit groove, and the slide plate is slidably connected to the slide groove, a handle is provided on the front side of the slide plate, so that the clamp mechanism can slide forward by pulling the handle on the front side of the slide plate, and there is no need for the operator to push the clamp mechanism from the rear of the base. The operator can complete all operations in front of the base, which is convenient for the operator to operate and improves production efficiency.

[0016] Furthermore, a driving rod is provided at the bottom of the driving frame, a one-way rack is provided at the front end of the driving rod, and the one-way rack is meshed with the one-way gear ring.

[0017] Through the above technical solution, since a driving rod is provided at the bottom of the driving frame and a one-way rack is provided at the front end of the driving rod, the one-way rack is meshed with the one-way gear ring, so that the rotation of the driving disk can drive the driving rod to slide in one direction, that is, the rotation of the driving disk can drive the driving rod to slide in the rear direction. When the driving rod needs to be reset, since the transmission member is vertically slidably connected to the rotating shaft at the bottom of the control motor, the transmission member can be lifted to disengage the transmission member from the engagement with the driving disk, thereby facilitating the resetting of the driving rod.

[0018] Furthermore, the limiting mechanism includes a limiting part, a transmission box and a driven part, the limiting part is rotatably connected to the base, the transmission box is fixedly connected to the side of the base, and the driven part is rotatably connected to the transmission box.

[0020] Through the above technical scheme, since one side of the limiting part is fixedly connected to the limiting block, the limiting block is rotatably connected in the limiting groove, and the other side of the limiting part is fixedly connected with a worm gear, the worm gear is arranged on the side of the base, and a worm is rotatably connected in the transmission box, the worm wheel is meshed with the worm, one end of the worm is fixedly connected with the first bevel gear, one end of the driven part is fixedly connected with the second bevel gear, and the other end of the driven part is fixedly connected with the driven gear, the first bevel gear and the second bevel gear are meshed, and the driven gear is arranged outside the transmission box, so that the rotation of the driven gear can drive the second bevel gear to rotate, the rotation of the second bevel gear can drive the first bevel gear to rotate, the rotation of the first bevel gear can drive the worm to rotate, the rotation of the worm can drive the worm wheel to rotate, and the rotation of the worm wheel can drive the limiting block to rotate, so that the limiting block can rotate downward and fall down, thereby releasing the restriction on the upper limit plate of the clamp mechanism.

[0021] Furthermore, a bracket is fixedly connected to the side of the base away from the slide groove, and the drive frame is slidably connected to the bracket. A transmission rod is also provided on the top of the drive frame, and a plurality of drive racks are provided on the top of the transmission rod corresponding to the limiting mechanism, and the drive racks are meshed with the driven gear.

[0022] Through the above technical solution, since a transmission rod is also provided on the top of the driving frame, a plurality of driving racks are provided on the top of the transmission rod corresponding to the limiting mechanism, and the driving racks are meshed with the driven gears, so that the sliding of the transmission rod can drive the sliding of the driving racks, and the sliding of the driving racks can drive the rotation of the driven gears;

[0023] When the control motor drives the bending mechanism to rotate to bend the metal tube, the driving rod can be driven to slide in the rear direction, and the sliding of the driving rod drives the transmission rod to slide in the rear direction, thereby driving the driven gear to rotate, that is, driving the limit block to rotate, releasing the restriction on the upper limit plate of the clamp mechanism, so that the metal tube can continue to move forward for the next bending after being bent once;

[0024] Due to the self-locking characteristics of the worm wheel and the worm, the limit block will not fall down and release the limit due to impact. During the resetting process of the driving rod, the transmission rod can be driven to slide forward, and then the worm can be driven to rotate in the opposite direction, and finally the limit block can be rotated in the opposite direction and stand up again, that is, the limit mechanism is also reset.

[0025] Furthermore, the guide wheel and the bending mechanism are both provided with half sleeves, the half sleeves on the guide wheel and the half sleeves on the bending mechanism can cooperate to clamp the metal tube, the front end of the half sleeve on the guide wheel is provided with a scale, and the metal tube is provided with a mark.

[0026] Through the above technical scheme, the half sleeve on the guide wheel and the half sleeve on the bending mechanism cooperate to clamp the metal tube, which can ensure the stability of the metal tube when bending and ensure the bending quality.

At the same time, the operator can complete all operations on the front side of the base, reducing the difficulty of operation for the operator and effectively improving production efficiency.

[0027] The beneficial effects of the present invention are as follows:

[0028] (1) In the present invention, the metal tube is installed on the clamp mechanism, and the front end of the metal tube passes between the bending mechanism and the guide wheel. The length of the metal tube to be bent can be adjusted by sliding the clamp mechanism forward. After the length is adjusted to the desired length, the control motor is started, and the bending mechanism and the guide wheel cooperate to bend the metal tube. The control motor can control the bending angle of the metal tube, and the setting of the limit mechanism can make the clamp mechanism stop sliding after sliding forward to a certain distance, that is, the limit mechanism can control the length of the metal tube, so that the operator can conveniently adjust the metal tube to the required bending length without measurement, which is convenient for the operator to operate and improves production efficiency;

[0029] (2) In the present invention, the motor controls the bending mechanism to bend the metal tube while driving the driving frame to slide. After the driving frame slides, the limiting mechanism is released, so that the metal tube can continue to move forward for the next bending. By setting multiple limiting mechanisms and releasing them in sequence, the bending length of the metal tube during multiple bending can be controlled. In this way, when the frame is bent multiple times during production, there is no need for the operator to measure the length each time, which is convenient for the operator's operation and effectively improves production efficiency.

[0030] (3) In the present invention, during the bending process of the entire frame, whether loading or unloading or adjusting the length or angle, the operator can complete all operations on the front side of the base, which reduces the difficulty of operation for the operator and effectively improves production efficiency. Compared with the fully automatic pipe bending machine, it saves equipment expenses and reduces production costs. Compared with the fully automatic pipe bending machine that requires more electronic systems to complete the program operation, the present invention is not only low in cost, but also has low equipment maintenance costs and is more stable when used for a long time.

[0048] In this embodiment, the metal tube 9 is installed on the clamp mechanism 8, and the front end of the metal tube 9 passes between the bending mechanism 2 and the guide wheel 3. The length of the metal tube 9 that needs to be bent can be adjusted by sliding the clamp mechanism 8 forward. After the length is adjusted, the control motor 4 is started, and the bending mechanism 2 and the guide wheel 3 can cooperate to bend the metal tube 9. The control motor 4 can control the bending angle of the metal tube 9, and the setting of the limit mechanism 7 can make the clamp mechanism 8 stop sliding after sliding forward to a certain distance, that is, the limit mechanism 7 can control the length of the metal tube 9, so that the operator can easily adjust the metal tube 9 to the required bending length without measurement, and the control motor 4 controls the bending mechanism 2 to bend the metal tube 9 while driving the driving frame 6 to slide.

[0050] In this embodiment, the clamp mechanism 8 can be slid forward by pulling the handle 831 on the front side of the slide plate 83. There is no need for the operator to push the clamp mechanism 8 from the rear of the base 1. The operator can complete all operations in front of the base 1, which is convenient for the operator to operate and improves production efficiency. The chuck 81 is rotatably connected to the clamp mechanism 8, so that the metal tube 9 clamped by the chuck 81 can be rotated to adjust the angle, which is convenient for bending the metal tube 9 in different plane directions and facilitating the production of the frame. The setting of the limit plate 82 cooperates with the limit mechanism 7 to determine the length of the metal tube 9 that needs to be bent, which is convenient for the operator to operate.

[0051] like Figure 2-Figure 4 As shown, the driving mechanism 5 includes a transmission member 51, a driving disk 52 and a bracket 53. The transmission member 51 is vertically slidably connected to the bottom shaft of the control motor 4, the bracket 53 is fixedly connected to the base 1, and the driving disk 52 is rotatably connected to the bracket 53;

[0052] The bottom shaft of the control motor 4 is provided with an internal spline 41, the transmission member 51 is provided with an external spline 511, the internal spline 41 meshes with the external spline 511, a transmission groove 521 is provided in the drive disc 52, a transmission tooth 512 is provided on the outer side of the transmission member 51, the transmission tooth 512 meshes with the transmission groove 521, and a one-way gear ring 522 is provided on the outer side of the drive disc 52;

[0053] A driving rod 61 is disposed at the bottom of the driving frame 6, and a one-way rack 611 is disposed at the front end of the driving rod 61, and the one-way rack 611 is meshed with the one-way gear ring 522;

[0054] In this embodiment, the rotation of the control motor 4 can drive the transmission member 51 to rotate, and the rotation of the transmission member 51 can drive the drive disk 52 to rotate. The rotation of the drive disk 52 can drive the drive rod 61 to slide in one direction, that is, the rotation of the drive disk 52 can drive the drive rod 61 to slide toward the rear side. When the drive rod 61 needs to be reset, since the transmission member 51 is vertically slidably connected to the bottom shaft of the control motor 4, the transmission member 51 can be lifted, so that the transmission member 51 is disengaged from the drive disk 52, which facilitates the reset of the drive rod 61.

[0055] like Figure 5-Figure 7As shown, the limiting mechanism 7 includes a limiting portion 71, a transmission box 72 and a driven portion 73, the limiting portion 71 is rotatably connected to the base 1, the transmission box 72 is fixedly connected to the side of the base 1, and the driven portion 73 is rotatably connected to the transmission box 72;

[0056] One side of the limiting portion 71 is fixedly connected to a limiting block 711, and the limiting block 711 is rotatably connected to the limiting groove 11. The other side of the limiting portion 71 is fixedly connected to a worm gear 712, and the worm gear 712 is arranged on the side of the base 1. A worm 721 is rotatably connected in the transmission box 72, and the worm gear 712 meshes with the worm 721. One end of the worm 721 is fixedly connected to a first bevel gear 722, and one end of the driven portion 73 is fixedly connected to a second bevel gear 731, and the other end of the driven portion 73 is fixedly connected to a driven gear 732, and the first bevel gear 722 and the second bevel gear 731 mesh, and the driven gear 732 is arranged outside the transmission box 72.

[0057] A bracket is fixedly connected to the side of the base 1 away from the slide groove 12, and the drive frame 6 is slidably connected to the bracket. A transmission rod 62 is also provided on the top of the drive frame 6. A plurality of drive racks 621 are provided on the top of the transmission rod 62 corresponding to the limiting mechanism 7, and the drive racks 621 are meshed with the driven gear 732.

[0058] In this embodiment, the transmission rod 62 slides to drive the driving rack 621 to slide, and the driving rack 621 slides to drive the driven gear 732 to rotate, and the driven gear 732 rotates to drive the second bevel gear 731 to rotate, and the second bevel gear 731 rotates to drive the first bevel gear 722 to rotate, and the first bevel gear 722 rotates to drive the worm 721 to rotate, and the worm 721 rotates to drive the worm wheel 712 to rotate, and the worm wheel 712 rotates to drive the limit block 711 to rotate, so that the limit block 711 can rotate downward and fall down, releasing the restriction on the upper limit plate 82 of the clamp mechanism 8;

[0059] When the control motor 4 drives the bending mechanism 2 to rotate to bend the metal tube 9, the driving rod 61 can be driven to slide in the rear direction. The sliding of the driving rod 61 drives the transmission rod 62 to slide in the rear direction, thereby driving the driven gear 732 to rotate, that is, driving the limit block 711 to rotate, and releasing the restriction on the upper limit plate 82 of the clamp mechanism 8, so that the metal tube 9 can continue to move forward for the next bending after being bent once;

[0060] Due to the self-locking characteristics of the worm wheel 712 and the worm 721, the limit block 711 will not fall down and release the limit due to impact. During the resetting process of the driving rod 61, the transmission rod 62 can be driven to slide toward the front side, and then the worm 721 can be driven to rotate in the opposite direction, and finally the limit block 711 can be rotated in the opposite direction and stand up again, that is, the limit mechanism 7 is also reset.

[0061] like Figure 1 and Fig. 9As shown, half sleeves are provided on the guide wheel 3 and the bending mechanism 2. The half sleeve on the guide wheel 3 and the half sleeve on the bending mechanism 2 can cooperate to clamp the metal tube 9. A scale 31 is provided at the front end of the half sleeve on the guide wheel 3, and a mark 91 is provided on the metal tube 9.

[0062] In this embodiment, the half sleeve on the guide wheel 3 and the half sleeve on the bending mechanism 2 cooperate to clamp the metal tube 9, which can ensure the stability of the metal tube 9 when bending and ensure the bending quality. The front end of the half sleeve on the guide wheel 3 is provided with a scale 31, and the metal tube 9 is provided with a mark 91. When the metal tube 9 needs to be bent in different plane directions, the angle of the metal tube 9 can be accurately rotated by comparing the scale 31 and the mark 91, thereby ensuring the bending quality of the metal tube 9. At the same time, the operator can complete all operations on the front side of the base 1, reducing the operating difficulty of the operator and effectively improving production efficiency.

[0063] Working principle:

[0064] During operation, the metal tube 9 is mounted on the clamp mechanism 8 through the clamp plate 81, and the front end of the metal tube 9 passes between the bending mechanism 2 and the guide wheel 3. The handle 831 on the front side of the slide plate 83 is pulled to allow the clamp mechanism 8 to slide forward. The clamp mechanism 8 slides forward to adjust the length of the metal tube 9 to be bent. The limit plate 82 on the clamp mechanism 8 slides forward in the limit groove 11 to the first limit block 711 and stops sliding forward. At this time, the first bending length of the metal tube 9 is just adjusted to the right position, and then the control motor 4 is started. The bending mechanism 2 and the guide wheel 3 cooperate to bend the metal tube 9, and the control motor 4 can control the bending angle of the metal tube 9.

[0065] The control motor 4 rotates to drive the bending mechanism 2 to rotate to bend the metal tube 9, and at the same time, the transmission member 51 can be driven to rotate. The rotation of the transmission member 51 can drive the driving disk 52 to rotate. The rotation of the driving disk 52 can drive the driving rod 61 to slide in one direction, that is, the rotation of the driving disk 52 can drive the driving rod 61 to slide in the rear direction. The sliding of the driving rod 61 drives the transmission rod 62 to slide in the rear direction. The sliding of the transmission rod 62 can drive the driving rack 621 to slide. The sliding of the driving rack 621 can drive the driven gear 732 to rotate. The rotation of the driven gear 732 can drive the second bevel gear 731 to rotate. The rotation of the second bevel gear 731 can drive the first bevel gear 722 to rotate. The rotation of the first bevel gear 722 can drive the worm 721 to rotate. The rotation of the worm 721 can drive the worm wheel 712 to rotate. The rotation of the worm wheel 712 can drive the limit block 711 to rotate, so that the limit block 711 can rotate downward and fall down, thereby releasing the restriction on the upper limit plate 82 of the clamp mechanism 8.

[0066] Due to the self-locking characteristics of the worm wheel 712 and the worm 721, the limit block 711 will not fall down and release the limit by itself due to impact. Only when the control motor 4 drives the bending mechanism 2 to rotate to bend the metal tube 9, the limit block 711 can rotate downward and fall down to release the restriction on the upper limit plate 82 of the clamp mechanism 8, so that the clamp mechanism 8 can continue to drive the metal tube 9 to slide forward for the next bending;

[0067] According to actual production needs, multiple limit mechanisms 7 are set at specific positions of the base 1. After the first bending is completed, the handle 831 on the front side of the slide plate 83 is pulled to continue to slide the clamp mechanism 8 forward, and the above steps are repeated to perform a second bending on the metal tube 9. By repeating the bending steps, multiple bendings of the metal tube 9 can be completed, that is, the bending of the frame can be completed. The distances between the multiple driving racks 621 on the transmission rod 62 and each corresponding driven gear 732 are different. The closer the driven gear 732 is to the front end of the base 1, the farther the distance between it and the corresponding driving rack 621 is. The multiple limit mechanisms 7 are released in sequence, so that the operator can easily adjust the metal tube 9 to the length required for bending without measurement. By setting multiple limit mechanisms 7 and releasing them in sequence, the bending length of the metal tube 9 during multiple bendings can be controlled. In this way, when the frame is bent multiple times during production, the operator does not need to measure the length each time, which is convenient for the operator's operation and effectively improves the production efficiency.

[0068] When the metal tube 9 needs to be bent in different plane directions during a certain bending, the metal tube 9 can be accurately rotated by comparing the scale 31 and the mark 91, thereby ensuring the bending quality of the metal tube 9;

[0069] After all the metal tubes 9 are bent, the operator can unload the bent metal tubes 9 from the front side of the base 1. At this time, the metal tube 9 to be processed can be installed on the clamping mechanism 8 through the clamping plate 81 at the front side of the base 1, and the clamping mechanism 8 is reset. Then, the transmission member 51 is lifted to make the transmission member 51 disengage from the engagement with the driving disk 52, and the driving rod 61 is pulled to reset the driving rod 61. During the reset process of the driving rod 61, the transmission rod 62 can be driven to slide toward the front side, and then the worm 721 can be driven to rotate in the opposite direction, and finally the limit block 711 is reversed and re-erected, that is, the limit mechanism 7 is also reset, and a new round of frame bending can be carried out at this time;

[0070] During the entire frame bending process, whether loading or unloading or adjusting the length or angle, the operator can complete all operations on the front side of the base 1, which reduces the difficulty of the operator's operation and effectively improves production efficiency.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
