Description
Technical Field
[0001] The invention relates to the technical field of hinge bushing processing equipment, in particular to an automatic automobile hinge bushing assembly equipment. Background Art
[0002] Door hinges are one of the most common parts on car doors. Door hinges are composed of hinge brackets, pins and other components. The hinge brackets and the pins are connected by a rotating card connection. The bushings between the hinge brackets and the pins can improve the stability of the pins rotating between the hinges, thereby increasing the service life of the hinges. Automobile hinge bushing assembly equipment is a mechanical equipment specially used for the installation and assembly of automobile door hinge brackets and bushings, thereby improving the subsequent overall assembly efficiency and service life of the hinges.
[0003] In the prior art, for example, the invention patent disclosed in the publication number CN106493545B is an assembly machine for automobile door hinge bushings, including a workbench and a feeding mechanism, a material receiving and pushing mechanism, a rod beating mechanism, a mold base and a PLC control device installed on the workbench. The feeding mechanism is connected to the material receiving and pushing mechanism and feeds the material receiving and pushing mechanism. The material receiving and pushing mechanism corresponds to the rod beating mechanism. The material receiving and pushing mechanism and the rod beating mechanism are both set to two and are located on both sides of the mold base. The PLC control device is electrically connected to the material receiving and pushing mechanism and the rod beating mechanism and controls the material receiving and pushing mechanism and the rod beating mechanism to work together. The bushings can be assembled on both sides of the hinge bracket at the same time. The rod beating mechanism is pressurized by the booster cylinder to ensure that the rod is driven to the bottom of the bushing and firmly combined with the bracket. By replacing the mold, hinges of various specifications can be quickly switched. The coordinated work of various components is realized by the PLC control device, and the degree of automation is high. The bushing process of the automobile door hinge can be completed quickly, and the production efficiency is high.
[0004] Although the above-mentioned equipment can perform press-fit assembly operations on the hinge bushing, the bushing in the above-mentioned equipment has no rigid limit after loading, so that the above-mentioned bushing is movably set inside the receiving block 33. When the above-mentioned hitting rod 42 deviates when aligning the bushing, the bushing is easily limited by the hitting rod 42, thereby affecting the stability of bushing loading. At the same time, the above-mentioned equipment only radially limits the hinge bracket through two sets of pins, and does not axially limit the hinge bracket, which makes the above-mentioned equipment insufficient in safety and stability when assembling the bushing of the hinge bracket. In addition, the above-mentioned equipment performs two-stage pressing on the bushing and the hinge bracket through the booster cylinder, which greatly prolongs the time for assembling the bushing and the hinge bracket and reduces the assembly efficiency. Therefore, an automated automobile hinge bushing assembly equipment is needed to solve the above-mentioned problems. Summary of the invention

[0071] A bushing assembly fixture 82 is provided at the end of the front end face of the spring clamping shaft 83, two sets of lateral positioning plates 81 for limiting are provided on the side of the linear slide 86, and an upper positioning plate 85 is provided at the upper part of the front end face of the linear slide 86, and a fixed slide rail 87 is fixedly provided at the center of the lower end face of the linear slide 86. The lateral positioning plates 81 and the upper positioning plates 85 can perform double rigid limiting on the sides and upper parts of the hinge bracket 1, which can effectively improve the stability of the limiting when the hinge bracket 1 is pressed and installed, and also improve the accuracy of subsequent positioning.
[0072] like Figure 1 and Figure 2The first bevel gear 10 in the middle is meshed with the second bevel gear 15, and the first bevel gears 10 on both sides are meshed with the third bevel gear 54, which can effectively improve the transmission stability of the equipment and thus improve the subsequent transmission efficiency;
[0073] The guide slide shaft 57 is adapted to the fixed slide rail 87, and the transmission device 5 is adapted to the fixed slide rail 87 through the guide slide shaft 57, thereby driving the bushing assembly device 8 to move forward and backward inside the support device 6. When the guide slide shaft 57 is cyclically rotated, it can slide and limit with the fixed slide rail 87, thereby driving the fixed slide rail 87 and the bushing assembly device 8 to move forward and backward as a whole, which can improve the stability of the bushing 2 being pressed into the hinge bracket 1.
[0074] like Fig.16 The guide slide 76 is slidably connected with the fixed slide shaft 712 through the linear bearing 75. The fixed slide shaft 712 and the positioning slide groove 67 are one up and one down, which can provide a sufficient limiting basis for the guide slide 76, improve the stability of the subsequent sliding displacement of the guide slide 76 at the bottom of the support device 6, and thus improve the stability of the material guiding of the hinge bracket 1;
[0075] The guide slide 76 is adapted to the cam guide groove 711 through the cam slide shaft 79 and then slidably engaged with the outer end surface of the transmission guide roller 710. The bracket baffle 77 and the loading guide plate 78 are both fitted and connected to the bottom of the bracket lower bin 14. The cam guide groove 711 is a circular track. The sliding limit of the cam slide shaft 79 can cyclically drive the guide slide 76 to move forward and backward, thereby facilitating the loading guide plate 78 to load the hinge bracket 1 with magazines one by one.
[0076] like Fig.18 and Fig.19 The ends of the lateral positioning plate 81 and the upper positioning plate 85 are provided with limited chamfers, and the lateral positioning plate 81 and the upper positioning plate 85 are both fitted and connected with the outer end surface of the hinge bracket 1. The limited chamfers inside the lateral positioning plate 81 and the upper positioning plate 85 can automatically align when the hinge bracket 1 is deflected after the material is loaded, so that the lateral positioning plate 81 and the upper positioning plate 85 can correct the position of the hinge bracket 1, thereby improving the accuracy of the subsequent pressing of the bushing 2 into the hinge bracket 1.
[0077] like Figure 1 The lateral positioning plate 81 and the upper positioning plate 85 are slidably engaged with the alignment guide groove 64, and the alignment guide groove 64 can provide sufficient guiding basis for the lateral positioning plate 81 and the upper positioning plate 85 to prevent the lateral positioning plate 81 and the upper positioning plate 85 from being limited by the side wall of the positioning guide seat 66 when the hinge bracket 1 is rigidly positioned later.
[0078] like Figure 8The width of the avoidance groove 65 is greater than the diameter of the bushing 2, and the width of the avoidance groove 65 is greater than the diameter of the bushing 2, which can provide sufficient guiding space for the press-fitting of the bushing 2.
[0079] The bottom of the bushing 2 is fitted and connected to the limit block 32, and the inner walls of the first wedge-shaped slider 35 and the second wedge-shaped slider 36 are fitted and connected to the bushing 2. The bushing unloading bin 31, the first wedge-shaped slider 35 and the second wedge-shaped slider 36 can rigidly limit the outside of the bushing 2 from each side, effectively improving the stability of subsequent unloading and guiding of the bushing 2.
[0080] Working principle: Figure 1 and Figure 4 Before use, the user can sequentially introduce multiple sets of hinge brackets 1 and bushings 2 to be assembled into the bracket lower bin 14 and the bushing lower bin 31, so that the subsequent bracket lower bin 14 and the bushing lower bin 31 can continuously supply hinge brackets 1 and bushings 2 to the assembly equipment;
[0081] like Figure 1 , Figure 2 and Figure 7 When transmitting, the user can start the servo motor 12 through the external control panel. The servo motor 12 can drive the second bevel gear 15 to rotate through the reduction motor 13. The second bevel gear 15 can drive the first bevel gear 10 on the side and the transmission card shaft 9 to mesh and rotate synchronously. At this time, the transmission card shaft 9 can mesh with the two sets of third bevel gears 54 through the two sets of first bevel gears 10, thereby providing transmission power for the transmission device 5, so that the transmission device 5 can provide power for the bushing assembly device 8 to circulate and feed the bushing 2, such as Figure 2 At the same time, the second bevel gear 15 can drive the fourth bevel gear 72 at the front to rotate synchronously, so that the fourth bevel gear 72 can provide the bracket feeding device 7 with power to guide the hinge bracket 1;
[0082] like Figure 1 and Figure 7 As shown, in the initial state, the feeding guide plate 78 and the bracket baffle 77 are at the rear end of the bracket lower bin 14, and the bottom hinge bracket 1 can fall to the upper part of the positioning guide seat 66 inside the bracket lower bin 14 under the action of gravity, completing the pre-feeding alignment. When the hinge bracket 1 is clip-guided, as in the above-mentioned transmission steps, refer to Figure 2 , Figure 3 and Fig.16As shown, the second bevel gear 15 can drive the fourth bevel gear 72 at the front to rotate synchronously, and the fourth bevel gear 72 can synchronously drive the synchronous pulley 73 at the rear to rotate. The upper and lower sets of synchronous pulleys 73 are driven by the synchronous belt 713 to rotate synchronously, so that the upper synchronous pulley 73 can synchronously drive the rear transmission guide roller 710 to rotate. When the above-mentioned transmission guide roller 710 rotates, the transmission guide roller 710 can synchronously drive the cam guide groove 711 to rotate. The cam guide groove 711 can drive the guide slide 76 and the feeding guide plate 78 to cyclically move forward and backward on the outside of the fixed slide shaft 712 through the cam slide shaft 79. At this time, Figure 5 and Fig.16 As shown, when the feeding guide plate 78 and the bracket baffle plate 77 move forward, the feeding guide plate 78 can push out the hinge bracket 1 at the bottom of the bracket lower bin 14, and at the same time, the bracket baffle plate 77 can block and limit the rear group of hinge brackets 1 until the feeding guide plate 78 drives the hinge bracket 1 to move to the side limit, as shown in FIG. Figure 4 , Figure 5 and Fig.15 At this time, the hinge bracket 1 is located in the middle of the alignment guide groove 64, thereby completing the loading operation of the hinge bracket 1;
[0083] like Figure 1 As shown, before the two sets of bushings 2 are pressed and assembled with the hinge bracket 1, the two sets of bushing assembly devices 8 are initially located at the limit close to the positioning guide seat 66, and at the same time, the tail of the positioning clamp 84 can limit the bushing 2 at the bottom of the bushing lower bin 31. As shown in the above transmission steps, when the servo motor 12 and the reduction motor 13 provide the bracket feeding device 7 with the feeding power for the hinge bracket 1 through the second bevel gear 15, the second bevel gear 15 can synchronously provide power for the two sets of bushing assembly devices 8 through the transmission clamp shaft 9 and the three sets of first bevel gears 10. When the transmission card shaft 9 rotates, the two sets of first bevel gears 10 and the two sets of third bevel gears 54 can be meshed to drive the two sets of side adjustment turntables 58 to rotate circularly inside the fixed rotating seat 55. When the adjustment turntable 58 rotates in a circle, it can synchronously drive the ball slide 56 and the guide slide shaft 57 to rotate in a circle. At this time, the guide slide shaft 57 faces the direction of the positioning guide seat 66. When the guide slide shaft 57 rotates, the guide slide shaft 57 can pass through the sliding limit with the fixed slide rail 87, thereby driving the fixed slide rail 87 to move backward inside the fixed side plate 62, such as Figure 5 When the feeding guide plate 78 drives the hinge bracket 1 to feed to the predetermined position on the upper part of the positioning guide seat 66, the guide slide shaft 57 rotates to the rear limit and drives the fixed slide rail 87 to move to the rear limit. At this time, the positioning seat 84 and the spring clamping shaft 83 are completely separated from the bushing lower bin 31, and the bushing 2 inside the bushing lower bin 31 falls under the action of gravity. Fig.10 , Fig.11 and Fig.13 When the bushing 2 falls inside the bushing lower bin 31, the two groups of limit blocks 32 at the bottom of the bushing lower bin 31 can limit the retaining edge of the bushing 2, and at the same time, the two groups of first wedge-shaped sliders 35 at the front and rear can limit the front and rear of the bushing 2 in all directions, thereby completing the rigid limit of the bushing 2 before loading. When the above-mentioned hinge bracket 1 is loaded, the loading guide plate 78 starts to return. At this time, the fixed slide rail 87 can start to move from back to front under the drive of the guide slide shaft 57, such as Fig.13 First, when the bushing assembly fixture 82 moves forward, it can press the two sets of first wedge-shaped sliders 35, so that the two sets of first wedge-shaped sliders 35 move sideways under the elastic force of the guide spring 37. At this time, the bushing assembly fixture 82 can be inserted into the bushing 2, and then the bushing assembly fixture 82 can press the two sets of second wedge-shaped sliders 36 to the side. When the second wedge-shaped sliders 36 move to the side, they can block the front of the bushing 2, so that the bushing 2 can be nested at the tail end of the bushing assembly fixture 82, thereby completing the feeding operation of the bushing 2, and then the spring clamping shaft 83 and the positioning clamping seat During the forward movement, the two sets of first wedge-shaped sliders 35 and second wedge-shaped sliders 36 can be completely pushed open, and the second wedge-shaped sliders 36 can limit the position of the latter set of bushings 2. As the fixed slide rails 87 continue to move, the two sets of lateral positioning plates 81 located on both sides of the positioning guide seat 66 can limit the bottom side walls of the hinge bracket 1, and the upper positioning plate 85 can limit the bottom top wall of the hinge bracket 1. The double positioning can make the hinge bracket 1 completely face the bushing assembly fixture 82. As the bushing assembly fixture 82 continues to move, Figure 7 and Figure 8 The bushing assembly fixture 82 can drive the bushing 2 to be inserted into the interior of the hinge bracket 1. After the insertion is completed, the above-mentioned fixed slide rail 87 continues to move under the drive of the guide slide shaft 57. At this time, the positioning seat 84 can drive the spring clamping shaft 83 to move forward, and the spring clamping shaft 83 elastically deforms, so that the two sets of bushing assembly fixtures 82 can completely press the bushing 2 to the two sides of the hinge bracket 1 with interference fit, and when the positioning seat 84 drives the spring clamping shaft 83 and the bushing assembly fixture 82 to move to the pressing limit, the spring clamping shaft 83 can always provide the bushing assembly fixture 82 with elastic force to press the bushing 2, so that the hinge bracket 1 has a continuous time and elastic force, which maximizes the stability of the bushing 2 pressed into the interior of the hinge bracket 1. After the pressing is completed, the above steps are continuously cycled, and the hinge bracket 1 that has been pressed is displaced toward the outside of the positioning guide seat 66 under the guidance of the next group of hinge brackets 1, which is convenient for subsequent automatic unloading.
