Description

Technical Field

[0001] The utility model relates to the technical field of part processing, and specifically, to a part processing and conveying device. Background Art

[0002] A part is a basic unit that constitutes a machine and is also a basic processing object in the manufacturing process.

[0003] In the machinery industry, a part refers to an indivisible single workpiece in a machine. In the automotive manufacturing industry, part processing is a key link. During the processing, it is necessary to convey the processed automotive parts from one process to the next process to make the automotive part processing production process continuous. Existing conveying equipment includes conveyor belts, rollers, chains, and conveyors, etc. During the conveying and processing of automotive parts, different workbenches or processing equipment usually have different heights, resulting in stagnation and waiting time in conveying, and further leading to processing errors. Therefore, it is necessary to adjust the height of the support frame of the conveying equipment.

[0004] The height adjustment of existing conveying equipment usually requires rotating the adjustment screws on the support frame with tools to change the height of the support frame. This kind of adjustment takes a certain amount of time and effort, especially in the case of frequent adjustment or a large adjustment range, resulting in a reduction in adjustment efficiency.

[0033] The following will further describe the technical solutions of the present utility model in detail through specific embodiments.

[0034] Embodiment 1

[0035] As Figure 1 , Figure 2 and Figure 3 shown, a part processing and conveying device includes a base 1, a lifting bracket and a belt conveyor 2;

[0036] The lifting bracket is installed on the base 1 and is used to support and drive the belt conveyor 2 to lift to adapt to workbenches of different heights;

[0037] The belt conveyor 2 is horizontally installed on the top of the lifting bracket and is used for part processing and conveying.

[0038] In this embodiment, the lifting bracket includes two X-shaped scissors frames, and the two X-shaped scissors frames are symmetrically arranged left and right;

[0039] The X-shaped scissor lift is mainly composed of a first support rod 4 and a second support rod 5 that cross each other and are hinged at the crossing point by a sliding pin 3. The first support rod 4 is inclined with the front end higher and the rear end lower, and the second support rod 5 is inclined with the front end lower and the rear end higher. A conveying frame 6 is also arranged directly above the first support rod 4 and the second support rod 5. The conveying frame 6 is a long support beam horizontally arranged in the front-rear direction. The lower ends of the first support rod 4 and the second support rod 5 are slidably connected to the base 1 in the front-rear direction, and the upper ends of the first support rod 4 and the second support rod 5 are slidably connected to the conveying frame 6 in the front-rear direction;

[0040] A first connecting rod 7 is fixedly connected between the lower ends of the two left and right corresponding first support rods 4 and is located above the rear side of the base 1. A second connecting rod 8 is fixedly connected between the lower ends of the two left and right corresponding second support rods 5 and is located above the front side of the base 1. Electric push rods 9 arranged in the front-rear direction are hinged between the first connecting rod 7 and the base 1 and between the second connecting rod 8 and the middle of the base 1;

[0041] The belt conveyor 2 is horizontally installed between the two conveying frames 6 in the front-rear direction.

[0042] In this embodiment, two chutes 10 are opened on the base 1 in the front-rear direction and are arranged at intervals left and right. Lower sliding blocks 11 are hinged at the lower ends of the first support rod 4 and the second support rod 5, and upper sliding blocks 12 are hinged at the upper ends of the first support rod 4 and the second support rod 5. The two lower sliding blocks 11 on the left are slidably installed in the left chute 10 correspondingly in the front-rear direction, and the two lower sliding blocks 11 on the right are slidably installed in the right chute 10 correspondingly in the front-rear direction. The two upper sliding blocks 12 on the left are slidably connected to the left conveying frame 6 correspondingly in the front-rear direction, and the two upper sliding blocks 12 on the right are slidably connected to the right conveying frame 6 correspondingly in the front-rear direction. Here, T-shaped or dovetail-shaped rail grooves can be opened on the side wall of the conveying frame 6 in the front-rear direction, and convex blocks that are integrally formed on the upper sliding blocks 12 and are matched and embedded and slid in the T-shaped or dovetail-shaped rail grooves.

[0043] In this embodiment, C-shaped connecting frames 13 with open upper sides are fixedly connected between the front and rear bottoms of the two conveying frames 6 and are located below the belt conveyor 2. Two telescopic rods 14 that are spaced front and rear and vertically arranged are fixedly connected to the base 1. The two telescopic rods 14 are respectively located directly below the two C-shaped connecting frames 13. The piston rods of the telescopic rods 14 extend from the upper ends of their cylinders, and the upper ends of the piston rods of the two telescopic rods 14 are respectively fixedly connected to the centers of the horizontal sections of the two C-shaped connecting frames 13.

[0044] The working principle of the part processing and conveying device is as follows: When the part processing is being conveyed, if it is necessary to increase the height of the part processing and conveying, the electric push rod 9 is energized and started. By controlling the contraction of the output end of the electric push rod 9, the two electric push rods 9 drive the first connecting rod 7 and the second connecting rod 8 to move synchronously towards each other. The first connecting rod 7 drives the lower ends of the two first support rods 4 to move backward towards the middle of the base 1, and at the same time, the second connecting rod 8 drives the lower ends of the two second support rods 5 to move forward towards the middle of the base 1. Then, the lower ends of the first support rod 4 and the second support rod 5 drive the corresponding lower sliding blocks 11 to slide towards each other in the corresponding sliding grooves 10. Since the first support rod 4 and the second support rod 5 cross each other and are hinged by a sliding pin 3 at the crossing point, the upper ends of the first support rod 4 and the second support rod 5 simultaneously drive the corresponding upper sliding blocks 12 to slide towards each other on the corresponding conveying frame 6. The first support rod 4 and the second support rod 5 generate relative rotation through the sliding pin 3, and the inclination angles of the first support rod 4 and the second support rod 5 relative to the horizontal plane increase, thereby lifting the conveying frame 6. The two conveying frames 6 drive the belt conveyor 2 to move upward, and the height of the part processing and conveying is increased. During the upward movement of the conveying frame 6, the telescopic rod 14 is stretched along with the conveying frame 6; on the contrary, if it is necessary to decrease the height of the part processing and conveying, only need to control the output ends of the two electric push rods 9 to extend. Then, the lower ends and the upper ends of the first support rod 4 and the second support rod 5 will move away from each other. The inclination angles of the first support rod 4 and the second support rod 5 relative to the horizontal plane decrease, thereby lowering the conveying frame 6. The two conveying frames 6 drive the belt conveyor 2 to move downward, and the height of the part processing and conveying is decreased. During the downward movement of the conveying frame 6, the telescopic rod 14 is compressed along with the conveying frame 6; Through the above operations, the height adjustment of the belt conveyor 2 can be realized for part processing and conveying, which can effectively adapt to workbenches of different heights, can quickly adjust the height of the belt conveyor 2, reduce the waste of operation time caused by manual adjustment, thereby effectively improving the overall efficiency of part processing, can realize the close cooperation between the belt conveyor 2 and the processing equipment, reduce the problem of processing errors caused by height differences, can enable the parts to smoothly transfer from one workstation to another workstation, can effectively reduce the stagnation and waiting time caused by the mismatch of conveying height during part processing, can effectively make flexible adjustments according to the layout of the actual production line, can effectively reduce unnecessary transfer and handling, and effectively improve the flexibility and adaptability of the production line.

[0045] Embodiment 2

[0046] As Figure 1 and Figure 3 shown, on the basis of Embodiment 1, part shifting and centering mechanisms are fixedly installed in the middle of the tops of the two conveying frames 6. The two part shifting and centering mechanisms have the same structure and are symmetrically arranged on the upper parts of the left and right sides of the belt conveyor 2;

[0047] The part-moving centering mechanism on the left side includes a fixed frame 15, which is L-shaped. The lower end of the vertical section of the fixed frame 15 is fixedly connected to the middle of the top of the conveying frame 6 on the left side. The horizontal section of the fixed frame 15 is arranged in the left and right directions. The left end of the horizontal section of the fixed frame 15 is integrally formed and fixedly connected with the upper end of the vertical section. The right end of the horizontal section of the fixed frame 15 extends to the upper middle of the left side of the belt conveyor 2. A vertically arranged first motor 16 is fixedly installed on the upper right end of the horizontal section of the fixed frame 15. The output end of the first motor 16 vertically penetrates the right end of the horizontal section of the fixed frame 15 downward. The output end of the first motor 16 is coaxially fixedly connected with a first rotating shaft 17 located below the horizontal section of the fixed frame 15. The lower end of the first rotating shaft 17 is higher than and close to the upper half of the conveyor belt of the belt conveyor 2. A plurality of shifting plates 18 arranged in a circumferential array are fixedly connected axially on the outer circumference of the first rotating shaft 17.

[0048] In this embodiment, the conveying direction of the belt conveyor 2 is from front to back, the paddle 18 is a curved arc plate, and the rotation direction of the output end of the first motor 16 is the same as the bending direction of the corresponding paddles 18 below it. Looking from top to bottom, the bending direction of the paddles 18 on the left is counterclockwise, and the bending direction of the paddles 18 on the right is clockwise.

[0049] During operation, when parts are conveyed by the belt conveyor 2, some parts may deviate during movement. The first motor 16 is powered on and turned on to rotate the output end of the first motor 16. At the same time, the output end of the first motor 16 drives the plurality of paddles 18 to rotate through the first rotating shaft 17. When the parts pass through the middle of the plurality of paddles 18 on the left and right sides, the deviated parts are moved by the paddles 18 to move the parts to the center of the conveyor belt of the belt conveyor 2 for conveyance. This can effectively reduce obstructions to subsequent processing procedures, reduce the operation time of stopping to adjust the position of parts, and can arrange the parts neatly, making the parts conveying process smoother, effectively reducing the problem of stacking chaos caused by deviation of the position of parts, and effectively improving the overall production efficiency of parts processing.

[0050] Embodiment 3

[0051] like Figure 1 , Figure 3 and Figure 4 As shown, buffer anti-drop components are also installed on the top of the conveyor frame 6 at the front and rear sides of the fixed frame 15. The two buffer anti-drop components have the same structure and are symmetrically arranged front and back;

[0052] The front buffer and anti-offset dropping component includes two fixing rods 19. At the front side of the fixing frame 15 on the top of the conveying frame 6, two fixing grooves 20 are provided at intervals in the front and rear directions. The front fixing groove 20 is close to the front end of the top of the conveying frame 6 and is aligned with the front end of the upper half of the conveyor belt of the belt conveyor 2. The rear fixing groove 20 is close to the middle of the top of the conveying frame 6 and is aligned with the outer side edge of the front baffle 18. The inner wall of the fixing groove 20 is provided with an internal thread groove. On the outer circumference of a section of the lower side of the middle of the fixing rod 19, an external thread groove 21 is axially provided. The external thread groove 21 is in threaded cooperation with the internal thread groove. The lower sides of the middles of the two fixing rods 19 are connected in the fixing groove 20 through the threaded cooperation of the external thread groove 21 and the internal thread groove. A section of the upper side of the middle of the fixing rod 19 is a smooth shaft and is coaxially rotatably connected with two rotating blocks 22 arranged at intervals up and down. An elastic cloth 23 is arranged between the two fixing rods 19 and above the conveying frame 6. The upper and lower parts of the front side edge of the elastic cloth 23 are respectively fixedly connected to the two front rotating blocks 22. The upper and lower parts of the rear side edge of the elastic cloth 23 are respectively fixedly connected to the two rear rotating blocks 22.

[0053] During operation, when the parts deviate during transportation, the parts deviating to the edge of the conveyor belt of the belt conveyor 2 will collide with the elastic cloth 23. The elastic cloth 23 blocks the parts, avoiding the dropping caused by the deviation of the parts during transportation. The elastic cloth 23 has good buffering performance and can effectively absorb part of the impact force, effectively reducing scratches and damages on the surface of the parts. Through the elastic cloth 23, a soft protective layer can be formed, effectively reducing the potential safety hazards caused by the accidental dropping of the parts, and improving the safety during the transportation of the parts.

[0054] Embodiment 4

[0055] As Figure 2 and Figure 3 shown, a cleaning component is also installed on the C-shaped connecting frame 13 and below the belt conveyor 2. The cleaning component includes a round rod 24. The round rod 24 is horizontally arranged in the left-right direction between the two vertical rods on both sides of the C-shaped connecting frame 13. The two ends of the round rod 24 are respectively rotatably connected to the two vertical rods on both sides of the C-shaped connecting frame 13. A spiral thread brush 25 is fixedly connected to the outer circumference of the round rod 24 along the axial direction. The thread brush 25 is in close contact with the surface of the conveyor belt of the belt conveyor 2.

[0056] During operation, when the parts are being conveyed by the belt conveyor 2, since the thread brushes 25 below both ends of the belt conveyor 2 are in close contact with the surface of the conveyor belt of the belt conveyor 2, the conveyor belt of the belt conveyor 2 will drive the thread brushes 25 and the round rods 24 to rotate. The thread brushes 25 can effectively remove the dirt and impurities adhering to the surface of the conveyor belt of the belt conveyor 2. The thread brushes 25 can closely adhere to the surface of the conveyor belt of the belt conveyor 2, increasing the contact area between the thread brushes 25 and the conveyor belt of the belt conveyor 2. The material of the thread brushes 25 is usually relatively soft and has a certain elasticity, which can reduce the scratching or damage to the surface of the conveyor belt of the belt conveyor 2 during the cleaning process, thereby protecting the integrity of the conveyor belt of the belt conveyor 2 during the cleaning process.

[0057] Example Five

[0058] As Figure 1 and Figure 5 As shown, a parts collection box 26 is also fixedly connected to the base 1 below one side of the output end of the belt conveyor 2. The upper opening of the parts collection box 26 is arranged directly opposite the output end of the belt conveyor 2. A second motor 27 is fixedly connected to the outside of the side wall of the parts collection box 26. The output end of the second motor 27 penetrates the side wall of the parts collection box 26 and extends into the interior of the parts collection box 26. The output end of the second motor 27 is coaxially fixedly connected to a second rotating shaft 28 horizontally arranged in the middle of the parts collection box 26. The other end of the second rotating shaft 28 is rotatably installed on the other side wall of the parts collection box 26 far from the second motor 27 through a rotating seat 29. A plurality of buffer plates 30 arranged in a circumferential array are fixedly connected along the axial direction on the outer circumference of the second rotating shaft 28.

[0059] During operation, after the parts are processed, the parts are conveyed by the belt conveyor 2 towards the parts collection box 26. The second motor 27 is powered on and started. The output end of the second motor 27 drives the second rotating shaft 28 to rotate. The second rotating shaft 28 drives each buffer plate 30 to rotate simultaneously. When the parts fall from the output end of the belt conveyor 2 into the interior of the parts collection box 26, the parts first fall on the buffer plates 30. The buffer plates 30 absorb the impact generated when the parts fall and are collected. Then, the buffer plates 30 rotate to make the parts enter the bottom of the parts collection box 26 for collection. The buffer plates 30 can provide a certain buffering effect when the parts fall into the interior of the parts collection box 26, which can effectively reduce the direct impact between the parts and the bottom of the parts collection box 26 or other parts, and effectively reduce the problem of parts being damaged due to the impact force during the falling process of the parts. The rotating buffer plates 30 can disperse the impact force of the parts falling into the interior of the parts collection box 26, reduce the concentrated load on the bottom and side walls of the parts collection box 26, and reduce the deformation and damage of the parts collection box 26 caused by long-term stress.

[0060] Furthermore, a sponge block 31 is fixedly covered on the outer surface of the buffer plate 30. When the parts fall on the buffer plate 30, the sponge block 31 contacts with the parts, which can avoid the direct contact between the parts and the buffer plate 30 when the parts fall, further buffer the impact force of the parts falling, and effectively reduce the noise and vibration generated by the direct impact of the parts on the buffer plate 30 and the bottom of the parts collection box 26, thereby reducing the pollution of the working environment by the noise.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: the specific implementation manners of the present invention can still be modified or some technical features can be equivalently replaced; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
