Description

Technical Field

[0001] This invention relates to the technical field of hinge bushing processing equipment, and in particular to a hinge bushing assembly equipment. Background Technology

[0002] Automotive door hinges are components used to connect the car body and doors. They are able to rotate around the same axis and engage with each other, including a fixed part and a hinge part. Adjacent hinge parts are connected by a pin. To avoid direct contact between the hinge parts, which would generate excessive friction and wear, bushings are required on the hinge parts. Traditionally, bushings and hinge parts are assembled manually. Hinges are placed one by one on a fixed loading position, and then the bushings are assembled onto the hinge parts of each hinge using a pressing device. This method suffers from low production efficiency and high operational difficulty. Furthermore, to ensure accurate bushing assembly, only hinges of the same specification can be positioned and processed at the same loading position, resulting in poor compatibility.

[0003] Therefore, based on the above-mentioned technical problems, this application proposes a hinge bushing assembly equipment with adjustable assembly position, high adaptability, low operation difficulty, and high production efficiency. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a hinge bushing assembly device with adjustable assembly position, high adaptability, low operation difficulty, and high production efficiency.

[0005] To achieve the above objectives, the present invention provides a hinge bushing assembly device, comprising a frame, a hinge feeding mechanism, and a bushing feeding mechanism, and further comprising a conveying mechanism, a fixed base, a top-loading mechanism, a moving loading mechanism, and a bushing assembly mechanism disposed on the frame. The conveying mechanism transports the hinge to be assembled provided by the hinge feeding mechanism to the fixed base. The top-loading mechanism pushes the hinge to be assembled to the assembly station of the fixed base. The moving loading mechanism receives the bushing supplied by the bushing feeding mechanism and assembles the received bushing onto the hinge to be assembled. The moving loading mechanism includes a secondary feeding slide, a primary guide rail, a secondary drive unit, at least one primary mounting block, a guide component, a loading block, and a tertiary drive unit. The secondary feeding slide is used to transport the bushing provided by the bushing feeding mechanism to the... In the moving loading mechanism, the loading block is used to receive the bushing output by the bushing feeding mechanism. The primary guide rail is arranged on the frame along the X-axis. The primary mounting block is slidably mounted on the primary guide rail, and the guide component is mounted on the primary mounting block. The movable end of the secondary drive unit is connected to one end of the guide component. The other end of the guide component is provided with a jaw portion, and a vertical through hole is formed on the jaw portion. The tertiary drive unit is mounted at the bottom end of the jaw portion, and the movable end of the tertiary drive unit moves vertically through the through hole. The loading block is mounted on the movable end of the tertiary drive unit. The movable rod of the tertiary drive unit and the secondary drive unit are used to drive the guide component to reciprocate along the primary guide rail, so that the bushing on the loading block is aligned with the hinge to be assembled position on the assembly station.

[0006] Furthermore, the hinge includes a hinge portion and a fixing portion, and the hinge portion is provided with an assembly hole for assembling the bushing.

[0007] Furthermore, the ejector mechanism includes a primary drive unit and an ejector component. The ejector component is fixed to the movable end of the primary drive unit. A through guide groove is formed on the other end of the fixed base along the X-axis direction. The primary drive unit is used to allow the ejector block to reciprocate along the guide groove.

[0008] Furthermore, the fixed base is also provided with a limiting block and a pressure spring. The limiting block is installed on one side of the assembly station, and the pressure spring is provided on the other side of the assembly station. The limiting block is provided with a guide part, wherein the bottom end of the guide part and the top end of the fixed base form a guide slide. The guide part is formed with a through clearance hole. The feeding station of the fixed base is provided with a stop part extending along the X-axis direction.

[0009] Furthermore, the conveying mechanism includes a primary feeding chute and a feeder. The primary feeding chute is connected to the discharge end of the hinge feeding mechanism and the inlet end of the fixed seat. The vibrating end of the feeder is connected to the bottom end of the primary feeding chute. The feeder is used to transport the hinge to be assembled on the primary feeding chute to the inlet end of the fixed seat.

[0010] Furthermore, the bushing assembly mechanism includes a secondary guide rail, at least one secondary mounting block, a connector, a loading rod, a four-stage drive unit, and a position sensor. The secondary guide rail is arranged on the frame along the Y-axis, the secondary mounting block is slidably mounted on the secondary guide rail, and the connector is mounted on the secondary mounting block. The two ends of the connector are respectively connected to the moving ends of the loading rod and the four-stage drive unit, wherein the top pressing end of the loading rod is aligned with the hinge assembly hole on the assembly station. The four-stage drive unit is used to drive the loading rod to reciprocate along the secondary guide rail, and the position sensor is used to monitor the relative position of the connector.

[0011] The present invention adopts the above-described solution, and its beneficial effects are as follows: Unlike traditional bushing assembly, which can only assemble hinges from a preset loading position, the hinge bushing assembly equipment in this embodiment uses components such as a fixed seat, guide slide, and pressure spring to adapt and fix the size of the fixed part of each hinge. At the same time, a moving loading mechanism is set up to cooperate with the above components to adjust the position in the X-axis direction before bushing assembly. This enables the accurate assembly of bushings of hinges of different sizes and specifications in sequence, achieving the function of adjustable bushing assembly position, reducing assembly difficulty, making assembly easier, and increasing production efficiency.

Detailed Implementation

[0021] To facilitate understanding of the present invention, a more complete description is given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0022] See appendix Figure 1-7As shown, XYZ axis coordinates are established as auxiliary references. In this embodiment, a hinge bushing assembly device includes a frame 1, a hinge feeding mechanism 2, and a bushing feeding mechanism 3. It also includes a conveying mechanism 4, a fixed base 5, a top-loading mechanism 6, a moving loading mechanism 7, and a bushing assembly mechanism 8, all mounted on the frame 1. The conveying mechanism 4 transports the hinge 9A to be assembled provided by the hinge feeding mechanism 2 to the fixed base 5. The top-loading mechanism 6 pushes the hinge 9A to be assembled to the assembly station of the fixed base 5. The moving loading mechanism 7 receives the bushing 9B supplied by the bushing feeding mechanism 3 and assembles the received bushing 9B onto the hinge to be assembled. Regarding the chain 9A, it should be noted that, as shown in the figure, the hinge 9A to be assembled in this embodiment includes a hinge part 9A1 and a fixing part 9A2. The hinge part 9A1 is provided with an assembly hole 9A11 for assembling the bushing 9B. One end of the bushing 9B is in a flattened state, and the other end is in an unprocessed state that can be inserted into the assembly hole 9A11. The diameter of the unprocessed end of the bushing 9B is less than or equal to the diameter of the assembly hole 9A11, which facilitates the insertion of the bushing 9B into the assembly hole 9A11. After the bushing 9B is assembled, the assembled hinge 9A is pushed and transported to the next process by the ejector mechanism 6.

[0023] See appendix Figure 6As shown, in this embodiment, the mobile loading mechanism 7 includes a secondary feeding chute 71, a primary guide rail 72, a secondary drive unit 73, at least one, preferably two, primary mounting blocks 74, a guide component 75, a loading block 76, and a tertiary drive unit 77. The secondary feeding chute 71 is used to transport the bushing 9B provided by the bushing feeding mechanism 3 to the mobile loading mechanism 7. The loading block 76 is used to receive the bushing 9B output by the bushing feeding mechanism 3. The primary guide rail 72 is arranged on the frame 1 along the X-axis direction. The primary mounting block 74 is slidably mounted on the primary guide rail 72, and the guide component 75 is mounted on the primary mounting block 74. The movable end of the secondary drive unit 73 is connected to one end of the guide component 75, and the other end of the guide component 75 is provided with a jaw portion 7. 51. A vertical through hole 7511 is formed on the jaw portion 751. A three-stage drive unit 77 is installed at the bottom end of the jaw portion 751, and the movable end of the three-stage drive unit 77 moves vertically through the through hole 7511. The loading block 76 is installed on the movable end of the three-stage drive unit 77. The movable rod of the three-stage drive unit 77 can be vertically driven by the three-stage drive unit 77 according to the vertical position of the assembly hole 9A11, so that the bushing 9B on the loading block 76 is aligned with the assembly hole 9A11, which is more convenient for subsequent top pressing assembly operations. The second-stage drive unit 73 is used to drive the guide component 75 to reciprocate along the first-stage guide rail 72, so that the bushing 9B on the loading block 76 is aligned with the hinge 9A to be assembled on the assembly station. Because the discharge end of the secondary feeding chute 71 and the assembly hole 9A11 of the hinge 9A on the assembly station are at different X-axis positions, the precise assembly of the hinge 9A bushing 9B is ensured through the movement and cooperation of the secondary drive unit 73 and the primary guide rail 72. See the attached diagram for a detailed assembly illustration. Figure 8 As shown.

[0024] See appendix Figure 3-5As shown, the fixed base 5 is further provided with a limiting block 51 and a pressure spring 52. The limiting block 51 is installed on one side of the assembly station, and the pressure spring 52 is installed on the other side of the assembly station. The limiting block 51 is provided with a guide part 53, wherein the bottom end of the guide part 53 and the top end of the fixed base 5 form a guide slide 54, and the thickness of the guide slide 54 is slightly less than or equal to the thickness of the fixing part 9A2 of the hinge 9A, so that the hinge 9A can move from the feeding station to the assembly station along the guide slide 54 under the pushing of the top material mechanism 6. The guide part 53 is formed with a through clearance hole 531. When the loading rod 84 inserts the bushing 9B into the assembly hole 9A11, the clearance hole 531 prevents the pressing end of the loading rod 84 from contacting the guide slide 54, thereby ensuring assembly accuracy and reducing subsequent maintenance. To reduce costs, the feeding station of the fixed seat 5 is provided with a stop part 55 extending along the X-axis. When the hinge 9A enters the feeding station under the transport mechanism 4, the stop part 55 stops and abuts against the hinge 9A, thereby preventing the hinge 9A from leaving the feeding station and ensuring that the subsequent assembly station can perform assembly processing. Specifically, when the hinge 9A moves from the feeding station to the assembly station, the guide part 53 and the pressure spring 52 cooperate to relatively limit the offset in the Y-axis direction, thereby improving the assembly accuracy. Secondly, the elastic tendency of the pressure spring 52 can be used to position hinges 9A of different sizes and specifications (the larger the width of the fixed part 9A2, the greater the compression of the pressure spring 52, and the smaller the width of the fixed part 9A2, the smaller the compression of the pressure spring 52), thereby realizing the assembly processing operation of the bushing 9B of the hinge 9A.

[0025] See appendix Figure 2 , 3 As shown, the conveying mechanism 4 further includes a primary feeding slide 41 and a feeder 42. The primary feeding slide 41 is connected to the discharge end of the hinge feeding mechanism 2 and the feed end of the fixed seat 5. The vibrating end of the feeder 42 is connected to the bottom end of the primary feeding slide 41. The feeder 42 is used to transport the hinges 9A to be assembled on the primary feeding slide 41 to the feed end of the fixed seat 5. Through the vibration of the feeder 42, the hinges 9A on the primary feeding slide 41 are adjusted relative to each other during vibration, so as to avoid the positional deviation caused by the continuous supply of the hinge feeding mechanism 2, which would cause the hinges 9A to detach from the primary feeding slide 41 or damage the other normal hinges 9A. Secondly, the frame 1 is provided with a mounting plate for adjusting the vertical position of the feeder 42 and corresponding connecting bolts. The specific installation height and installation position can be adjusted according to the actual production needs, and no specific restrictions are made here.

[0026] See appendix Figure 3 , 4As shown, in this embodiment, the ejector mechanism 6 includes a primary drive unit 61 and an ejector component 62. The ejector component 62 is fixed to the movable end of the primary drive unit 61. The other end of the fixed base 5 has a through guide groove 56 formed along the X-axis direction. The primary drive unit 61 is used to allow the ejector block to reciprocate along the guide groove 56. Through the movement cooperation between the primary drive unit 61 and the ejector block, the function of pushing the hinge 9A from the feeding station to the assembly station and the next process is realized.

[0027] See appendix Figure 7 As shown, the bushing assembly mechanism 8 further includes a secondary guide rail 81, at least one, preferably two, secondary mounting blocks 82, a connector 83, a loading rod 84, a fourth-stage drive unit 85, and a position sensor 86. The secondary guide rail 81 is arranged on the frame 1 along the Y-axis direction. The secondary mounting blocks 82 are slidably mounted on the secondary guide rail 81, and the connector 83 is mounted on the secondary mounting blocks 82. The two ends of the connector 83 are respectively connected to the movable ends of the loading rod 84 and the fourth-stage drive unit 85, wherein the top pressing end of the loading rod 84 is connected to the assembly... The hinge 9A and the assembly hole 9A11 on the workstation are aligned; the four-stage drive unit 85 is used to drive the loading rod 84 to reciprocate along the secondary guide rail 81, so that the loading rod 84 pushes the bushing 9B from the loading block 76 to the assembly hole 9A11, realizing the assembly of the hinge 9A and the bushing 9B. The position sensor 86 is used to monitor the relative position of the connector 83, so that the operator can control the assembly progress in real time in the background, improve production efficiency, and avoid excessive movement of the loading rod 84, which could damage the hinge 9A or the bushing 9B and reduce production costs.

[0028] It should be noted that the pressing end of the loading rod 84 has a chamfer, and the diameter of the pressing end of the loading rod 84 is slightly larger than or equal to the diameter of the inner cavity of the bushing 9B. By setting a chamfer on the pressing end of the loading rod 84, it is easier for the pressing end to extend into the inner cavity of the bushing 9B. After the rod part of the loading rod 84 contacts the inner cavity of the bushing 9B, the loading rod 84 pushes the bushing 9B away from the loading block 76, so that the workpiece bushing 9B is assembled onto the hinge 9A.

[0029] The aforementioned primary drive unit 61, secondary drive unit 73, and tertiary drive unit 77 are all provided with mounting bases for fixing them to the frame 1. The specific positions can be set according to the actual production situation.

Any modifications or variations made by those skilled in the art, without departing from the scope of the present invention, using the disclosed technical content, are equivalent embodiments of the present invention.
