Description

Technical Field

[0001] The invention relates to the technical field of automobile accessories in the emerging strategic industry, in particular to an automobile radiator water inlet elbow bevel cutting device. Background Art

[0002] As we all know, the car radiator water inlet elbow is a curved water pipe, which is generally made of two straight pipes that are tilted and butt-welded. By adopting this method, the inside of the elbow can be guaranteed to have a higher fluidity, and it is avoided that when the straight pipe is directly squeezed and bent, the bending part of the straight pipe is concave and causes the pipeline to be blocked. The function of the elbow is to connect the radiator with the water channel in the car, and by making the pipe curved, the pipeline can be easily connected.

[0003] The processing of pipe bending first requires beveling the straight pipe to make the cut inclined, and then the two beveled straight pipes are butt-welded at the cut position to form a pipe bending. The traditional beveling method is that workers place the straight pipe at an angle and close to the cutter so that the cutter directly bevels the straight pipe. However, when using this method, the inclination angle of the cut cannot be accurately controlled, resulting in poor beveling accuracy.

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0035] like Figures 1 to 6 As shown, a car radiator water inlet elbow pipe bevel cutting device of the present invention comprises a mobile platform 1 and a screw 2, wherein the mobile platform 1 is used for horizontally conveying a plurality of straight pipes, the screw 2 is located above the mobile platform 1, and the length direction of the screw 2 is perpendicular to the moving direction of the mobile platform 1, a threaded sleeve 3 is provided on the screw 2, a translation rod 4 is fixed at the bottom of the threaded sleeve 3, and a laser cutter 5 is fixed at the bottom of the translation rod 4.

[0036] Specifically, a plurality of straight tubes are arranged and fixed on the mobile platform 1 in sequence, and the mobile platform 1 carries the plurality of straight tubes for horizontal transportation. When the mobile platform 1 moves to the position of the screw 2, the screw 2 rotates, and the screw 2 drives the threaded sleeve 3 thereon to move linearly along the axial direction of the screw 2. The threaded sleeve 3 drives the laser cutter 5 to move linearly through the translation rod 4, so that the moving direction of the laser cutter 5 is perpendicular to the moving direction of the mobile platform 1. When a straight tube on the mobile platform 1 approaches the laser cutter 5, the laser cutter 5 is turned on and cuts the straight tube. Since the mobile platform 1 and the laser cutter 5 are both in a moving state and the moving direction is arranged, the cutting track of the laser cutter 5 on the straight tube on the mobile platform 1 is tilted, thereby realizing the beveling processing of the straight tube. After the laser cutter 5 completes beveling of a straight tube, the laser cutter 5 is reset. When the next straight tube moves to the bottom of the laser cutter 5, the laser cutter 5 repeats the beveling processing on it, thereby realizing continuous automatic beveling processing of the straight tube.

[0037] By making the conveying direction of the straight tube perpendicular to the moving direction of the laser cutter 5 and moving them synchronously, the laser cutter 5 can conveniently perform automatic beveling processing on the straight tube, effectively simplifying the processing method, improving work efficiency, saving manpower, and realizing the continuous processing method of the straight tube. At the same time, it effectively improves the beveling accuracy and improves the processing quality.

[0038] In actual use, the incision inclination angle can be adjusted by controlling the conveying speed of the mobile platform 1 or the moving speed of the laser cutter 5, thereby effectively improving the functionality of the equipment and improving the processing accuracy.

[0039] When the laser cutter 5 moves between two adjacent straight tubes, the screw 2 is rotated in the opposite direction, and the screw 2 drives the laser cutter 5 to reset, thereby facilitating the beveling of the next straight tube. When the beveling angle is adjusted, the end point of the beveling of the straight tube by the laser cutter 5 is always between two adjacent straight tubes.

[0040] like Figures 1 to 5 As shown, as a preferred embodiment of the above embodiment, it also includes an outer box body 6, which is located outside the mobile platform 1, and a conveying structure is arranged inside the outer box body 6, and the number of the mobile platforms 1 is set to be multiple and all are installed on the conveying structure;

[0041] Two first support plates 7 are arranged on the top of the outer box body 6, the lead screw 2 is located between the two first support plates 7 and is rotatably mounted on the two first support plates 7, a sliding opening is opened on the top of the outer box body 6, the translation rod 4 passes through the sliding opening and extends into the outer box body 6, and the translation rod 4 is slidably mounted on the sliding opening;

[0042] The conveying structure includes two transmission belts 9, which are located on the front and rear sides of the outer box body 6, and multiple mobile platforms 1 are located between the two transmission belts 9. Two transmission wheels 8 are arranged inside the transmission belt 9 for transmission, and the transmission wheels 8 are rotatably installed on the inner wall of the outer box body 6. Two motors 10 are arranged on the outer wall of the outer box body 6, and the output end of the motor 10 is connected to a transmission wheel 8 in the transmission belt 9 for transmission. Two connecting shafts 11 are arranged on the side wall of the mobile platform 1 facing the transmission belt 9 for rotation, and the outer ends of the connecting shafts 11 are fixed on the transmission belt 9.

[0043] Specifically, when the lead screw 2 rotates, the lead screw 2 drives the translation rod 4 to slide in the sliding mouth, and the first support plate 7 supports the lead screw 2. The motor 10 can drive the transmission wheel 8 and the transmission belt 9 to transmit synchronously. The transmission belt 9 drives the mobile platform 1 to move through the connecting shaft 11, thereby realizing the continuous transportation of multiple mobile platforms 1. The external robotic arm can place the straight tubes on the mobile platform 1 one by one. By adopting the method of using the transmission belt 9 to drive the two connecting shafts 11, the stability of the movement of the mobile platform 1 can be improved.

[0044] like Figure 4 As shown, as a preferred embodiment of the above, two guide plates 12 are arranged between the two transmission belts 9, the two guide plates 12 are located on both sides of the mobile platform 1, the guide plates 12 are fixed on the inner side wall of the outer box body 6, and an annular guide groove 13 is opened on the side wall of the guide plate 12;

[0045] Two second support plates 14 are fixed to the back of the mobile platform 1 . Guide columns 15 are arranged on the second support plates 14 . The outer ends of the guide columns 15 are slidably installed in the annular guide grooves 13 .

[0046] Specifically, when the mobile platform 1 moves, the mobile platform 1 drives the two guide columns 15 to slide in the annular guide groove 13 through the two second support plates 14. By adopting this structure, the mobile platform 1 can be conveniently guided and supported, thereby improving the stability and firmness of the mobile platform 1 during movement, avoiding the mobile platform 1 from shaking or flipping, thereby effectively improving the positioning accuracy and stability of straight pipe transportation.

[0047] like Figure 1 , Figure 2 and Figure 5 As shown, as a preferred embodiment of the above, the mobile platform 1 is provided with multiple groups of clamping structures, the clamping structures are used to fix the straight pipe, the clamping structures include a first arc-shaped extrusion plate 16 fixed on the mobile platform 1 and a second arc-shaped extrusion plate 17 rotatably mounted on the mobile platform 1, the first arc-shaped extrusion plate 16 is opposite to the second arc-shaped extrusion plate 17, and the outer end of the second arc-shaped extrusion plate 17 is rotatably provided with a third arc-shaped extrusion plate 18;

[0048] The movable platform 1 and the second arc-shaped extrusion plate 17 are both provided with a limit block 19, the limit block 19 on the movable platform 1 contacts the outer wall of the second arc-shaped extrusion plate 17, the limit block 19 on the second arc-shaped extrusion plate 17 contacts the outer wall of the third arc-shaped extrusion plate 18, a leaf spring 20 is connected between the third arc-shaped extrusion plate 18 and the movable platform 1, a plurality of top columns 21 are provided on the outer wall of the third arc-shaped extrusion plate 18, and the outer ends of the top columns 21 are provided in a spherical shape;

[0049] A first wedge block 22 is arranged in the outer box body 6 , and the inclined surface of the first wedge block 22 faces the input direction of the transmission belt 9 and is inclined on the vertical plane. A plurality of cylinders 23 are arranged on the outer box body 6 , and the movable ends of the cylinders 23 are connected to the first wedge block 22 .

[0050] Specifically, the upper limit block 19 of the mobile platform 1 can limit the second arc extrusion plate 17, and the upper limit block 19 of the second arc extrusion plate 17 can limit the third arc extrusion plate 18. Since the third arc extrusion plate 18 is connected to the mobile platform 1 by the leaf spring 20, the leaf spring 20 generates an elastic thrust on the third arc extrusion plate 18 that is inclined toward the outside of the third arc extrusion plate 18, so that the third arc extrusion plate 18 and the second arc extrusion plate 17 are in a tensioned state, and the straight tube is placed between the first arc extrusion plate 16 and the second arc extrusion plate 17. When the transmission belt 9 is conveying, the mobile platform 1 and the straight tube move synchronously, and the top column 21 on the third arc extrusion plate 18 approaches the inclined surface of the first wedge block 22, and the inclined surface of the first wedge block 22 can be pushed by the top column 21 The third arc extrusion plate 18 rotates, and the third arc extrusion plate 18 and the second arc extrusion plate 17 approach toward the outer wall of the straight tube and are buckled on the outer wall of the straight tube. At this time, the first arc extrusion plate 16, the second arc extrusion plate 17 and the third arc extrusion plate 18 perform three-point extrusion and fixing work on the straight tube. When the straight tube is fixed, the top column 21 slides to the bottom plane of the first wedge block 22 and moves linearly. At this time, the first arc extrusion plate 16, the second arc extrusion plate 17 and the third arc extrusion plate 18 maintain the clamping and fixing work on the straight tube, thereby realizing the fixation of the straight tube on the mobile platform 1, avoiding the straight tube from rotating and affecting the bevel cutting accuracy when the laser cutter 5 cuts the straight tube. The cylinder 23 can drive the first wedge block 22 to move up and down, thereby adjusting the position of the first wedge block 22.

[0051] like Figure 2 As shown, as a preferred embodiment of the above embodiment, a second wedge block 24 is arranged in the outer box body 6, the inclined surface of the second wedge block 24 faces the input direction of the transmission belt 9 and is inclined on the horizontal plane, and two threaded rods 25 are rotatably arranged on the outer side wall of the second wedge block 24, the outer ends of the threaded rods 25 pass through the outer box body 6 and are threadedly connected, and a first spur gear 26 is arranged on the outer end of the threaded rod 25, and a second spur gear 27 is meshed between the two first spur gears 26, and the second spur gear 27 is rotatably installed on the outer wall of the outer box body 6, and the second spur gear 27 is fixed to the outer box body 6 by bolt extrusion.

[0052] Specifically, when the straight tube on the mobile platform 1 follows the mobile platform 1 for horizontal transportation, the outer end of the straight tube contacts the inclined surface of the second wedge block 24, and the second wedge block 24 pushes the straight tube for positioning, so that the outer end position of the second wedge block 24 is fixed, and it is convenient to position the position of the incision on the straight tube on the straight tube, and rotate the second spur gear 27. The second spur gear 27 can drive the two threaded rods 25 to rotate through the two first spur gears 26. The threaded rods 25 move on the outer box body 6, thereby adjusting the position of the second wedge block 24. At this time, the first spur gear 26 and the second spur gear 27 produce relative sliding and always maintain a meshing state. By setting a bolt between the second spur gear 27 and the outer box body 6, the position of the second spur gear 27 can be conveniently locked.

[0053] In actual use, the second wedge block 24 first positions the straight tube, and the first wedge block 22 then fixes the straight tube through the first arc-shaped extrusion plate 16 , the second arc-shaped extrusion plate 17 and the third arc-shaped extrusion plate 18 .

[0054] like Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, as a preferred embodiment of the above embodiment, the mobile platform 1 is provided with a plurality of tooth rows 28, and the plurality of tooth rows 28 correspond one to one with the plurality of clamping structures;

[0055] A transmission disc 31 is rotatably provided on the inner side wall of the outer box body 6, a first transmission shaft 30 is provided on the transmission disc 31, a third spur gear 29 is provided on the outer end of the first transmission shaft 30, a transmission wheel 32 is provided on the transmission disc 31 for transmission, a polygonal shaft 33 is provided on the transmission wheel 32, a second transmission shaft 34 is provided on the outer end of the polygonal shaft 33, and the outer end of the polygonal shaft 33 is slidably inserted into the second transmission shaft 34, the outer end of the second transmission shaft 34 passes through the outer box body 6 and is rotatably connected, a first bevel gear 35 is provided on the outer end of the second transmission shaft 34, a second bevel gear 36 is meshed with the first bevel gear 35, and the second bevel gear 36 is transmission-connected to the lead screw 2;

[0056] A support ring 37 is rotatably sleeved on the transmission wheel 32, and a plurality of adjustment cylinders 38 are arranged on the support ring 37. The fixed ends of the adjustment cylinders 38 are fixed on the inner wall of the outer box body 6.

[0057] The threaded sleeve 3 is provided with an elastic structure, and the elastic structure is used to pull the threaded sleeve 3 to reset.

[0058] Specifically, the tooth row 28 can be meshed and connected with the third spur gear 29. When the mobile platform 1 moves, the mobile platform 1 drives the multiple tooth rows 28 thereon to move synchronously. When the tooth row 28 is meshed with the third spur gear 29, the tooth row 28 pushes the third spur gear 29 to rotate. The third spur gear 29 drives the lead screw 2 to rotate through the first transmission shaft 30, the transmission plate 31, the transmission wheel 32, the polygonal shaft 33, the second transmission shaft 34, the first bevel gear 35 and the second bevel gear 36, thereby driving the laser cutter 5 to move, realizing the synchronous movement state of the laser cutter 5 and the mobile platform 1, and making it convenient for the mobile platform 1 to provide power for the laser cutter 5, avoiding the cost investment of setting up a power structure separately for the laser cutter 5, simplifying the structural method, realizing the linkage state, facilitating subsequent maintenance and replacement, and improving the synchronization of the movement of the mobile platform 1 and the laser cutter 5.

[0059] By adjusting the oil cylinder 38 and the support ring 37, the position of the transmission wheel 32 on the transmission disk 31 can be adjusted, thereby adjusting the transmission ratio between the transmission disk 31 and the transmission wheel 32, which is convenient for adjusting the moving speed of the laser cutter 5 and realizing the adjustment of the incision inclination angle. The oil cylinder 38 and the support ring 37 can be adjusted to support the transmission wheel 32. When the transmission wheel 32 moves, the transmission wheel 32 drives the polygonal shaft 33 to slide in the second transmission shaft 34.

[0060] When the laser cutter 5 completes cutting of the straight tube and moves to the end position, the laser cutter 5 is located between two adjacent straight tubes. At this time, the tooth row 28 is separated from the third spur gear 29. The elastic structure can pull the laser cutter 5 to reset through the threaded sleeve 3, and the third spur gear 29 rotates in the opposite direction and resets, so as to facilitate the laser cutter 5 to perform bevel cutting on the next straight tube. At the same time, due to the reset of the third spur gear 29, the initial position of the third spur gear 29 and the angle of the teeth thereon can be positioned, so as to facilitate the next tooth row 28 to move smoothly to the position of the third spur gear 29 and mesh, thereby avoiding the tooth jamming between the tooth row 28 and the third spur gear 29.

[0061] like Figure 6 As shown, as a preferred embodiment of the above embodiment, the elastic structure includes a third support plate 39 installed on the threaded sleeve 3, a sliding rod 40 is fixed between the two first support plates 7, the sliding rod 40 passes through the third support plate 39 and is slidably connected, a spring 41 is sleeved on the sliding rod 40, one end of the spring 41 is fixed on the third support plate 39, and the other end of the spring 41 is fixed on one of the first support plates 7.

[0062] Specifically, when the threaded sleeve 3 moves in a direction away from the initial position, the threaded sleeve 3 pulls the spring 41 through the third support plate 39 to cause elastic deformation. When the laser cutter 5 completes cutting, the tooth row 28 separates from the third spur gear 29. The spring 41 can pull the threaded sleeve 3 and the laser cutter 5 to reset through the third support plate 39. The slide rod 40 can guide the spring 41 and the third support plate 39.

[0063] like Figure 5 As shown, as a preference of the above embodiment, a storage groove 42 is provided on the working surface of the mobile platform 1 .

[0064] Specifically, by setting up the storage groove 42, the cut straight tube residues can be conveniently dropped directly into the storage groove 42 for easy collection. When the straight tube is cut and transported to one end of the transmission belt 9, the mobile platform 1 is rotated from a horizontal state to a vertical state. At this time, the residues in the storage groove 42 fall directly into the collecting device, while the finished straight tubes are between the second arc extrusion plate 17 and the third arc extrusion plate 18. When the mobile platform 1 moves to the bottom of the transmission belt 9, the second arc extrusion plate 17 and the third arc extrusion plate 18 cannot lift the finished straight tubes, and the straight tubes fall directly into the collecting device, thereby realizing the classified collection of residues and finished products.

[0065] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention.
