Technical Field

[0001] The invention relates to the technical field of steering knuckle processing, in particular to a fully automatic integrated machine tool for pressing and boring a steering knuckle bushing. Background Art

[0002] The steering knuckle is a part used in automobiles. Figure 2 As shown, it includes a shaft end 21 and a frame end 23. A bearing position 22 is provided on the shaft end 21, and two main pin holes 24 are provided on the frame end 23. A bushing 56 with an interference fit needs to be pressed into the main pin hole 24. The existing bushing 56 is generally pressed using a bushing press machine. The bushing needs to be manually loaded and placed on the press head, and then the bushing is pressed into the main pin hole by the press head, which is very inconvenient to use. After the bushing is pressed into the main pin hole, the steering knuckle needs to be transferred to a fine boring machine to perform fine boring on the main pin hole. The whole process requires multiple clamping of the steering knuckle, which is cumbersome to operate, wastes a lot of time, and affects processing efficiency. Summary of the invention In view of the deficiencies in the prior art, the present invention provides a fully automatic integrated machine tool for pressing and boring steering knuckle bushings. The entire clamping, loading, pressing and boring processes of the steering knuckle are fully automated. Personnel only need to place the steering knuckle on a clamping mechanism, which is easy to operate, saves time and effort, and greatly improves processing efficiency.

The pressing mechanism is provided with a pressing head for pressing the bushing; a feeding mechanism is provided between the pressing mechanism and the clamping mechanism, and the feeding mechanism includes a feeding box fixed on the machine base, the feeding box is inclined and extends with a low front and a high rear, a feeding port is provided at the rear end of the feeding box, a discharge port is provided at the front end of the feeding box, a slideway for accommodating the bushing is provided inside the feeding box, a limiting telescopic cylinder is provided on the front end outer wall of the feeding box, the telescopic end of the limiting telescopic cylinder extends into the slideway, and an induction receiver for receiving the bushing is provided below the discharge port.

[0004] This solution clamps the steering knuckle by the clamping components of the clamping mechanism to achieve clamping and fixing of the steering knuckle. Since the upper end surface of the machine base is tilted, the clamping structure tilts forward to face the operator, which is convenient for the operator to place and clamp the steering knuckle. The automatic loading of the bushing is achieved through the feeding mechanism. The feeding box is tilted. The bushing automatically slides from the feed port to the discharge port in the slideway. The automatic discharge is achieved by the telescopic end of the limit telescopic cylinder. When discharging, the bushing falls onto the induction receiver. The bushing is pressed by the press-fitting mechanisms on the left and right sides. The two press-fitting mechanisms slide left and right, and the bushings on the two induction receivers are pressed into the two kingpin holes of the steering knuckle by the press-fitting head. The clamping mechanism slides forward again, and the kingpin holes after press-fitting are bored by the boring mechanisms on the left and right sides. The two boring mechanisms slide left and right, and the two kingpin holes of the steering knuckle are bored synchronously by the boring heads.

The operation is simple and the clamping efficiency is higher.

[0008] As an optimization, the clamping assembly includes a first telescopic cylinder and a pressure rod fixed on the support plate, one end of the pressure rod is hinged to the telescopic end of the first telescopic cylinder, the other end of the pressure rod is in contact with the frame end, and the middle part of the pressure rod is hinged to the first telescopic cylinder through a connecting rod. This optimization scheme drives the pressure rod to rotate around the connecting rod through the telescopic movement of the first telescopic cylinder, so that the end of the pressure rod is pressed on the frame end face of the steering knuckle, thereby realizing automatic clamping of the clamping assembly.

[0009] As an optimization, the boring mechanism is slidably arranged on the machine base through a second sliding mechanism, the second sliding mechanism includes a bottom plate fixed to the machine base, a second guide rail extending left and right is fixed to the bottom plate, a second slide is slidably connected to the second guide rail, a second driver for driving the second slide to slide is provided on the bottom plate, and the boring mechanism is fixedly installed on the second slide.

As an optimization, the press-fitting mechanism includes a press-fitting shaft and the press-fitting head, one end of the press-fitting shaft is fixedly connected to the third slide, and the other end of the press-fitting shaft extends in a direction away from the third driver and is fixedly connected to the press-fitting head.

[0011] As an optimization, it also includes a bushing limiting mechanism, the bushing positioning mechanism includes a first motor, a connecting rod and a support rod, the first motor is fixed on a fixed platform of one of the third sliding mechanisms, the support rod extends in the left-right direction, one end of the support rod is fixedly connected to the output end of the first motor, and the other end of the support rod is rotatably connected to the fixed platform of another third sliding mechanism, the positioning rod extends in the front-back direction, one end of the positioning rod is fixedly connected to the support rod, and the other end of the positioning rod is located between the two main pin holes of the steering knuckle and is provided with two induction baffles, and the two induction baffles respectively block the two main pin holes.

The debris from boring in this optimization solution falls from the blanking hole into the material receiving box for collection, which is convenient for cleaning.

[0013] The beneficial effects of the present invention are as follows: the present solution clamps the steering knuckle together through the clamping components of the clamping mechanism to achieve clamping and fixing of the steering knuckle. Since the upper end surface of the machine base is tilted, the clamping structure tilts forward to face the operator, which is convenient for the operator to place and clamp the steering knuckle. Automatic loading of the bushing is achieved through the feeding mechanism. The slideway in the feeding box is tilted. The bushing automatically slides from the rear end to the front end in the slideway. Automatic discharge is achieved through the telescopic end of the limit telescopic cylinder.

[0015] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0016] like Figures 1 to 14 As shown, a fully automatic integrated machine tool for press-fitting and boring steering knuckle bushings comprises a machine base 10 and a clamping mechanism 3, two boring mechanisms 100 and two press-fitting mechanisms 6 arranged on the upper end surface of the machine base 10. The upper end surface of the machine base 10 is an inclined surface with a lower front and a higher rear. The inclination angle of the upper end surface of the machine base 10 in this embodiment is 45 degrees to 60 degrees. This inclination angle allows a person to extend his arm forward to contact the clamping mechanism on the upper end surface, so that the person can place the steering knuckle. Compared with the horizontal end surface of the existing machine tool, the person does not need to bend forward to work, which is more ergonomic and greatly improves the comfort of the person's operation.

[0017] The clamping mechanism 3 is arranged to slide forward and backward, and is used to clamp and fix the steering knuckle 2 . The boring mechanism 100 and the pressing mechanism 6 are distributed forward and backward along the sliding direction of the clamping mechanism 3 .

[0018] like Figure 5 As shown, specifically, the clamping mechanism 3 is slidably arranged on the base 10 through the first sliding mechanism 4, the first sliding mechanism 4 includes a first guide rail 41 extending forward and backward, and a first slide 42 slidably connected to the first guide rail 41, the base 10 is fixedly provided with a first driver for driving the first slide 42 to slide, and the clamping mechanism 3 is fixedly installed on the first slide 42. In this embodiment, two first guide rails 41 are arranged in the middle of the upper end surface of the base 10, and the first slide 42 is slidably connected with the two first guide rails 41 to improve the sliding stability of the first slide. And the first driver is a second telescopic cylinder 43, the telescopic end of the second telescopic cylinder 43 is fixedly connected to the first slide 42, and the first slide is driven to slide along the first guide rail by the telescopic movement of the second telescopic cylinder.

[0019] like Figure 5 , 6 As shown, preferably, in this embodiment, both front and rear ends of the first guide rail 41 are fixedly connected to limit plates 16, and the two limit plates 16 are respectively located in front of and behind the first slide 42. The limit plates 16 are provided with inductive limiters 17 opposite to the first slide 42, and the sliding position of the first slide is located by the inductive limiter.

[0020] like Fig.14 As shown, preferably, a material drop hole 15 is provided on the machine base 10 and is located below the clamping mechanism 3. The material drop hole 15 extends along the sliding direction of the clamping mechanism 3, and a material receiving box 14 is provided below the material drop hole 15. In this embodiment, the material drop hole 15 is located between the two first guide rails 41, so that the machining debris of the steering knuckle falls from the material drop hole into the material receiving box.

[0021] like Figure 3 As shown, specifically, the clamping mechanism 3 includes a support plate 31 and two groups of clamping components 34 fixed on the support plate 31. The support plate 31 is fixedly connected to the first slide 42. A positioning hole 32 is provided in the middle of the support plate 31 for the shaft end 21 of the steering knuckle 2 to pass through. Since the support plate 31 is fixed on the first slide 42, the positioning hole 32 of this embodiment sequentially penetrates the support plate 31 and the first slide 42 and is connected to the blanking hole 15.

[0022] like Figure 3 , 4As shown, a positioning sleeve 33 is fixedly connected to the top of the support plate 31, the positioning sleeve 33 and the positioning hole 32 are coaxial, and the inner diameter of the positioning sleeve 33 is adapted to the outer diameter of the bearing position 22 of the shaft end 21, and the two clamping assemblies 34 are located at the front and rear sides of the positioning sleeve 33 and work together to clamp the frame end 23 of the steering knuckle 2. When clamping, the shaft end 21 of the steering knuckle 2 passes through the positioning hole 32, and the frame end 23 of the steering knuckle 2 fits on the support plate 31, so that the center lines of the two main pin holes 24 of the frame end 23 are on the same horizontal line, and the frame end 23 is clamped by the two clamping assemblies 34 to achieve the clamping and fixing of the steering knuckle 2.

[0023] like Figure 3 As shown, specifically, the clamping assembly 34 includes a first telescopic cylinder 341 and a pressure rod 342 fixed on the support plate 31, one end of the pressure rod 342 is hinged to the telescopic end of the first telescopic cylinder 341, the other end of the pressure rod 342 is in contact with the frame end 23, and the middle part of the pressure rod 342 is hinged to the first telescopic cylinder 341 through a connecting rod 343. In this embodiment, the first telescopic cylinder 341 is vertically arranged, and the fixed end of the first telescopic cylinder is fixed to the support plate. One end of the connecting rod 343 is hinged to the middle part of the pressure rod 342, and the other end of the connecting rod 343 is hinged to the first telescopic cylinder 341. When the telescopic end of the first telescopic cylinder is extended, the pressure rod is driven to rotate around the connecting rod and pressed on the end face of the steering knuckle frame, thereby clamping and fixing the steering knuckle.

[0024] like Fig.12 As shown, the two press-fitting mechanisms 6 are symmetrically distributed on the left and right sides of the clamping mechanism 3 and are slidably arranged left and right. The press-fitting mechanism 6 is provided with a press-fitting head 61 for press-fitting the bushing 46 .

[0025] like Fig. 9 , 12 As shown, specifically, two press-fitting mechanisms 6 are located at the rear of the upper end surface of the machine base 10. The press-fitting mechanism 6 is slidably arranged on the machine base 10 through a third sliding mechanism 7, and the third sliding mechanism 7 includes a fixed table 71 fixedly connected to the machine base 10, and a third guide rail 72 extending left and right is provided on the fixed table 71, and a third slide 73 is slidably connected to the third guide rail 72, and a third driver for driving the third slide 73 to slide is provided on the fixed table 71. The press-fitting mechanism 6 described in this embodiment is located on the side of the third slide 73 close to the clamping mechanism 3, and the third driver is located on the side of the third slide 73 away from the clamping mechanism 3. The third driver is a third telescopic cylinder 74, and the telescopic end of the third telescopic cylinder 74 is fixedly connected to the third slide 73. The third slide is driven to slide along the third guide rail by the telescopic movement of the third telescopic cylinder, so that the press-fitting mechanism is close to the clamping mechanism to press the bushing.

[0026] like Fig. 9As shown, specifically, the press-fitting mechanism 6 includes a press-fitting shaft 62 and a press-fitting head 61, one end of the press-fitting shaft 62 is fixedly connected to the third slide 73, and the other end of the press-fitting shaft 62 extends in a direction away from the third driver and is fixedly connected to the press-fitting head 61. In this embodiment, the press-fitting head 61 is a cylinder, and the outer diameter of the press-fitting head 61 is adapted to the outer diameter of the bushing 56. An outwardly convex circular boss is provided at one end of the press-fitting head 61 away from the press-fitting shaft 62, and the outer diameter of the circular boss is adapted to the inner diameter of the bushing 56. The press-fitting head 61 is inserted into the bushing 56 through the circular boss, thereby pushing the bushing to be pressed into the main pin hole 24 of the steering knuckle.

[0027] To facilitate the positioning of the press-fitting head 61 and the kingpin hole 24, when the first slide 42 slides backward and contacts the rear inductive limiter 17, the center of the kingpin hole 24 of the steering knuckle and the axis of the press-fitting head 61 are located on the same axis. At this time, as the press-fitting mechanism 6 slides, the press-fitting head 61 can press the bushing 56 into the kingpin hole 24.

[0028] like Fig.12 As shown, a feeding mechanism 5 is provided between the pressing mechanism 6 and the clamping mechanism 3. In this embodiment, the feeding mechanism 5 is provided on both the left and right sides of the clamping mechanism 3. Figure 7 , 8 As shown, the feeding mechanism 5 includes a feeding box 51 fixed on the machine base 10, the feeding box 51 is inclined and extends with the front lower and the rear higher, a feeding port is provided at the rear end of the feeding box, and a discharge port is provided at the front end of the feeding box. A slideway 53 for accommodating the bushing 56 is provided inside the feeding box 51, and the slideway 53 extends along the length direction of the feeding box 51, and the two ends of the slideway are respectively connected with the feeding port and the discharge port. A limit telescopic cylinder 55 is provided on the front end outer wall of the feeding box 51, and the telescopic end of the limit telescopic cylinder 55 extends into the slideway 53. An induction receiver 54 for receiving the bushing 56 is provided below the discharge port, and the axis of the bushing 56 received by the induction receiver 54 is located on the same axis as the axis of the press fitting head 61.

[0029] like Figure 8 As shown, specifically, two groups of slideways 53 are distributed up and down in the loading box 51, and the two groups of slideways 53 are parallel. Two limit telescopic cylinders 55 are provided on the front outer wall of the loading box 51, and the telescopic ends of the two limit telescopic cylinders 55 extend into the two slideways 53 respectively. The opening and closing of the discharge port is realized by the telescopic movement of the limit telescopic cylinder 55, thereby realizing automatic loading. When the telescopic end of the limit telescopic cylinder 55 is extended, the telescopic end extends into the slideway 53 and presses on the bushing 56, thereby preventing the bushing from sliding off. When the telescopic end of the limit telescopic cylinder contracts, the bushing 56 is discharged from the discharge port along the inclined slideway 53 and falls onto the induction receiver 54, thereby realizing automatic loading and making loading more convenient.

[0030] The loading box 51 in this embodiment is fixed to the machine base 10 via a mounting plate 52. The mounting plate 52 is located between the first sliding mechanism 4 and the third sliding mechanism 7. The front end of the loading box 51 is fixedly connected to the mounting plate 52. The mounting plate 52 is provided with a through hole for the pressing head 61 to pass through.

[0031] In this embodiment, the front end of the loading box 51 is bent downward to form a discharge port opening downward, and the induction receiver 54 is arranged directly below the discharge port, so that the bushing sliding down the slideway can fall onto the induction receiver through the discharge port.

The first motor 81 is fixed on a fixed platform 71 of one of the third sliding mechanisms 7, and the support rod 82 extends in the left-right direction. One end of the support rod 82 is fixedly connected to the output end of the first motor 81, and the other end of the support rod 82 is rotatably connected to the fixed platform 71 of another third sliding mechanism 7. The positioning rod 83 extends in the front-back direction. One end of the positioning rod 83 is fixedly connected to the support rod 82, and the other end of the positioning rod 83 is located between the two main pin holes 24 of the steering knuckle and is provided with two induction baffles 84. The two induction baffles 84 respectively block the two main pin holes 24.

[0033] like Fig.11 As shown, specifically, the two induction baffles 84 are located on the left and right sides of the positioning rod 83, and the support rod 82 is driven to rotate by the first motor 81, thereby driving the rotation of the positioning rod 83. When the positioning rod 83 rotates away from one end of the support rod 82 to between the two main pin holes 24, the two induction baffles 84 respectively contact the two side walls opposite to the two main pin holes 24, thereby blocking the main pin holes.

[0034] The support rod 82 of the present embodiment extends in the left-right direction and passes through the mounting plates 52 of the two feeding mechanisms 5 . The mounting plates 52 are provided with through holes for the support rod 82 to pass through.

[0037] In this embodiment, two second guide rails 92 are provided on the base plate 91, and the second slide 93 is connected to the two second guide rails 92 to improve the stability of the second slide. The second driver is a nut-screw pair, and the nut-screw pair includes a screw 95, a nut, and a second motor 94. The screw 95 is located between the two second guide rails 92 and extends in the left-right direction. The two ends of the screw 95 are rotatably mounted on the base plate 91 through a bearing seat. The nut is screwed with the screw 95 and fixedly connected to the bottom of the second slide 93. The second motor 94 is fixed on the base plate 91, and the output end of the second motor 94 is fixedly connected to one end of the screw 95. The screw 95 is driven to rotate by the second motor 94, so that the screwed nut drives the second slide 93 to slide along the second guide rail 92, thereby moving the boring mechanism 100 in the direction of the clamping mechanism 3.

[0038] like Fig.13 As shown, specifically, the boring mechanism 100 includes a crankshaft output box 101, a reduction box 103, a boring head 102 and a third motor 104. The boring head 102 is fixedly connected to the output end of the crankshaft output box 101, the input end of the crankshaft output box is connected to the output end of the reduction box 103, and the output end of the third motor 104 is connected to the input end of the reduction box. The third motor 104 provides power to drive the output end of the crankshaft output box 101 to rotate, thereby rotating the boring head 102, and the reduction box 103 is used for deceleration. The boring mechanism 100 used in this embodiment is an existing conventional technology, which will not be described in detail here.

[0039] To facilitate the positioning of the boring head 102 and the kingpin hole 24, when the first slide 42 slides forward and contacts the front inductive limiter 17, the center of the kingpin hole 24 of the steering knuckle and the axis of the boring head 102 are located on the same axis. At this time, as the boring mechanism slides, the boring head can bore the kingpin hole.

[0040] It also includes an outer cabin 1, the base 10 and the clamping mechanism 3, the pressing mechanism 6 and the boring mechanism 100 on the base are all located in the outer cabin, and a door 11 is provided on the front side of the outer cabin 1 to facilitate personnel to clamp the steering knuckle, and an observation window 12 is provided on the door 11. A numerical control box 13 is provided on the outer cabin 1, and a controller is provided in the numerical control box 13. The limit telescopic cylinder 55, the first telescopic cylinder 341, the second telescopic cylinder 43, and the third telescopic cylinder 74 described in this embodiment are all electronically controlled cylinders, and the limit telescopic cylinder 55, the first telescopic cylinder 431, the second telescopic cylinder 43, the third telescopic cylinder 74, the first motor 81, the second motor 94, the third motor 104, the inductive limiter 17, the inductive baffle 84, and the inductive material receiver 54 are all connected to the controller by electrical signals. The controller controls each process flow to automatically operate, and the control system of the controller can be implemented by a technician in the relevant field through programming, and no relevant elaboration is given here.

[0041] The control flow of the controller is as follows: before processing, the personnel put the bushing 56 into the slideway 53 of the two feeding mechanisms 5, and the bushing 56 slides along the inclined slideway 53 to the discharge port to wait for feeding. The shaft end 21 of the steering knuckle 2 is inserted into the positioning hole 32 of the clamping mechanism 3, and the first telescopic cylinder 341 of the clamping assembly 3 is extended by the controller to make the pressure rod 342 press the frame end 23 of the steering knuckle 2, and the steering knuckle 2 is clamped and fixed.

[0042] The second telescopic cylinder 43 of the first sliding mechanism 4 is controlled to contract and drive the first slide 42 to slide backward. When the first slide 42 contacts the inductive limiter 17 at the rear, the inductive limiter 17 feeds back a signal to the controller, and the controller controls the second telescopic cylinder 43 to stop contracting. At this time, the main pin hole 24 of the steering knuckle 2 and the pressing head 61 of the pressing mechanism 6 are on the same axis.

[0043] The first motor 81 of the bushing positioning mechanism 8 is controlled to rotate forward to drive the support rod 82 to rotate, and the rotation of the support rod 82 drives the rotation of the positioning rod 83, and the end of the positioning rod 83 away from the support rod 82 rotates to between the two main pin holes 24, so that the induction baffles 84 on both sides respectively block the inner sides of the two main pin holes 24. At the same time, one of the limit telescopic cylinders 55 of the feeding mechanism 5 is controlled to shrink. When the induction material receiver 54 receives a bushing 56, the induction material receiver 54 feeds back a signal to the controller, and the controller controls the limit telescopic cylinder 55 to extend, thereby preventing the subsequent bushing from falling, and completing the automatic feeding of the bushing.

[0044] The third telescopic cylinder 74 of the two third sliding mechanisms 7 is controlled to extend and drive the third slide 73 to slide in the direction close to the clamping mechanism 3, and the two press-fitting mechanisms 6 are synchronously operated, so that the press-fitting head 61 pushes the bushing 56 on the induction material catcher 54 into the main pin hole 24. When the bushing 56 contacts the induction baffle 84, the induction baffle 84 feeds back a signal to the controller, controls the third telescopic cylinder 74 to contract, resets the press-fitting mechanism 6, and controls the first motor 81 to reverse, resets the bushing positioning mechanism 8, and completes the bushing press-fitting.

[0045] After press-fitting, the second telescopic cylinder 43 of the first sliding mechanism 4 is extended to drive the first slide 42 to slide forward. When the first slide 42 contacts the front inductive limiter 17, it stops extending. At this time, the main pin hole 24 and the boring head 102 of the boring mechanism 100 are on the same axis.

[0046] The second motor 94 of the two second sliding mechanisms 9 is controlled to rotate forward to drive the second slide 93 to slide in the direction close to the clamping mechanism 3. The second sliding mechanism 9 is set by the controller to control the sliding distance of the second slide 93. When the second slide 93 slides to the preset position, it stops. At this time, the boring head 102 of the boring mechanism 100 contacts the main pin hole 24. The third motor 104 of the boring mechanism is started to drive the boring head 102 to rotate and bore. The boring time is set by the controller. When the time is reached, the third motor 104 stops, and the second motor 94 reverses to drive the boring mechanism 100 to reset, completing the boring.

[0047] After boring, the first telescopic cylinder 341 of the clamping assembly 3 is controlled to retract, and the clamping of the steering knuckle by the pressure rod is cancelled, and the personnel can take out the steering knuckle, completing the whole process operation.
