Abstract
Description
Technical Field
[0001] This invention relates to the field of fuel injector seat machining technology, and more specifically to a keyway machining equipment for fuel injector seats. Background Technology
[0002] Fuel injectors are precision components requiring extremely high machining accuracy. They must have a wide dynamic flow range, strong anti-clogging and anti-contamination capabilities, and excellent atomization performance. The fuel injector receives injection pulse signals from the ECU and precisely controls the fuel injection quantity. The spray characteristics of the fuel injector include atomization particle size, fuel mist distribution, fuel jet direction, range, and diffusion cone angle. These characteristics must meet the requirements of the diesel engine combustion system to ensure complete air-fuel mixture formation and combustion, resulting in high power and thermal efficiency. The fuel injector mount is the base used to install the fuel injector.
[0003] As the mounting base for fixing fuel injectors, the injector holder needs to have a keyway on it to secure the injector. During the machining process, the injector holder is typically milled using a milling machine to form the keyway. However, the milling cutters on the milling machine are extremely sharp and rotate at very high speeds. If the operator accidentally touches the milling cutter or gets too close to it during the keyway machining process, the cutter and flying metal fragments can cause injury. Moreover, the operator faces this risk every time they machine an injector holder. Furthermore, when performing large-scale, long-term keyway machining of injector holders, the operator needs to continuously move the injector holders to the machining area, increasing the workload. Summary of the Invention

The bottom of the baffle near the horizontal feeding assembly is in contact with a limiting plate with both ends welded to the fixed frame.
[0010] The transverse feeding assembly includes a support frame, the top of which is fixedly connected to a material support frame by bolts; a lower auxiliary rod is fixedly connected to the lower end of the support frame, and an upper auxiliary rod is fixedly connected to the middle; rollers are rotatably connected to both ends of the lower and upper auxiliary rods.
[0011] The conveyor belt is provided with a housing on its outer side, and the inner walls of both sides of the housing are provided with a first groove and a second groove; the two ends of the upper auxiliary rod are slidably connected to the two first grooves through rollers; the two ends of the lower auxiliary rod are slidably connected to the two second grooves through rollers.
[0012] As a further technical solution of the present invention, the chassis is provided with two symmetrical limiting grooves at one end near the vertical feeding component; the fixed frame is provided with two symmetrical limiting posts at one end away from the rotating blocking mechanism, and the two limiting posts are located inside the two limiting grooves respectively; the other ends of the two limiting posts are each welded with a baffle plate, and the two baffle plates are located outside the chassis.
[0013] As a further technical solution of the present invention, both ends of the upper drive shaft, upper guide shaft, lower guide shaft and middle drive shaft are rotatably connected to the inner wall of the chassis; one end of the lower drive shaft is rotatably connected to the inner wall of the chassis, and the other end is fixedly connected to the output shaft of the servo motor, which is fixedly connected to the bottom inner side of the chassis by bolts.
[0014] As a further technical solution of the present invention, the chassis is provided with heat dissipation holes on the side near the servo motor, and the position of the heat dissipation holes corresponds to the position of the servo motor.
[0015] As a further technical solution of the present invention, the top of the chassis is provided with a feed inlet and a discharge outlet, wherein the feed inlet is located above the horizontal feeding assembly and the discharge outlet is located above the vertical feeding assembly; a feed protection plate is welded to the inner side of the feed inlet, the material support frame of the horizontal feeding assembly is located inside the feed protection plate, and the feed protection plate has an opening for the material support frame to pass through at one end near the vertical feeding assembly; a discharge protection plate is welded to the inner side of the discharge outlet, and the inner dimension of the discharge protection plate is larger than the dimension of the fixed frame.
[0016] As a further technical solution of the present invention, the two actuating plates are respectively attached to the bottom sides of the support frame, and the width of the two support frames is smaller than the width of the support frame.
[0017] As a further technical solution of the present invention, both the fixing frame and the material support frame are U-shaped, and the width of the fixing frame is smaller than the width of the material support frame.
[0018] As a further technical solution of the present invention, the two connecting ribs are fixedly connected to the side of the conveyor belt near the transverse feeding assembly; the length of the conveyor belt above the protruding part is the same as the length of the protruding part of the conveyor belt.
[0019] A method for machining a keyway for an injector seat includes the following steps:
[0020] Step 1: Placing the injector seat. First, the worker places the injector seat to be processed onto the support frame of the horizontal feeding assembly through the feed inlet. The support frame is U-shaped and has a support plate welded to its inner side to support the injector seat. The inner length of the support frame is slightly longer than the length of the injector seat, which not only allows the injector seat to be placed smoothly into the support frame, but also prevents the injector seat from shifting during transportation, so that the injector seat will not fall off the support frame during transportation. The support frame fixedly connected to the bottom of the support frame plays a supporting role, increasing the stability of the support frame and preventing the support frame from shaking when moving, thereby preventing the injector seat on the support frame from shifting.
[0021] The injector holder is transported laterally. After the injector holder is placed into the support frame, the servo motor drives the lower drive shaft to rotate, which in turn moves the conveyor belt. The servo motor controls the lower drive shaft to rotate in the opposite direction, and the conveyor belt moves in the opposite direction synchronously, which in turn moves two actuating plates. The two actuating plates move the support frame, which in turn moves the entire lateral feeding assembly towards the direction of the vertical feeding assembly. When the lateral feeding assembly moves, the lower and upper auxiliary rods on the support frame provide support and prevent the support frame from tilting. In addition, the rollers at both ends of the lower and upper auxiliary rods roll in the first and second grooves respectively, which are in sync with the movement speed of the lateral feeding assembly, making the lateral feeding assembly move more smoothly and reducing the pressure on the two actuating plates when they move the lateral feeding assembly.
[0022] Step 3: Injector seat repositioning. As the horizontal feeding assembly moves laterally towards the vertical feeding assembly, the conveyor belt simultaneously drives the vertical feeding assembly upwards. When the vertical and horizontal feeding assemblies intersect, the fixing frame of the vertical feeding assembly enters the inner side of the material support frame of the horizontal feeding assembly. At this point, the injector seat on the material support frame, driven by the material support frame, contacts the rotating baffle mechanism. As the injector seat moves further laterally, it presses against and down on the baffle plate of the baffle mechanism, causing the baffle plate to rotate around the connecting shaft. At this time, the torsion spring generates elastic energy. After the injector seat passes through the baffle mechanism, the pressure on the baffle plate disappears. The elastic force generated by the torsion spring controls the baffle plate to quickly return to its original position, allowing it to re-engage with the limit plate. At this point, the injector seat has moved onto the fixed frame. Once the injector seat is on the fixed frame, the baffle mechanism can block the injector seat, limiting its range of motion and preventing it from falling off the fixed frame due to excessive displacement. The limit plate can also block the baffle plate's range of motion, ensuring that the baffle plate rotates within a limited range, allowing the baffle mechanism to effectively limit the injector seat's movement.
[0023] Step four: Vertical transport of the injector holder. After the injector holder is moved onto the vertical feeding assembly, the vertical feeding assembly continues to move upward under the drive of the conveyor belt until it reaches the top of the conveyor belt. At this time, the vertical feeding assembly is close to the discharge port, and the operator can take the injector holder out of the fixed frame through the discharge port. The inlet protective plate of the inlet and the outlet protective plate of the outlet can limit the range of motion of the operator when placing or picking up the injector holder, so that the operator's hands and arms will not accidentally touch the moving parts inside the equipment, and prevent the moving parts from causing injury to the operator.
[0024] Step 5: Reset. After the injector housing is transported, the servo motor controls the conveyor belt to move forward via the lower drive shaft. As the conveyor belt moves, it drives the vertical feeding assembly downward, while the two actuating plates drive the horizontal feeding assembly towards the inlet. This continues until the vertical and horizontal feeding assemblies reach their initial positions and stop. At this point, the operator can place the injector housing into the support frame again from the inlet to begin the next injector housing transport operation. When the vertical feeding assembly moves vertically, the two limit posts move synchronously in the two limit slots. The two limit slots, in conjunction with the two limit posts, ensure the stability of the vertical feeding assembly while ensuring its normal movement, preventing excessive vibration.
[0025] (3) Beneficial effects:
[0026] A. In this invention, the worker first places the injector seat to be processed onto the support frame of the horizontal feeding assembly through the feed inlet. The support frame is U-shaped and has a support plate welded to its inner side to support the injector seat. The length of the inner side of the support frame is slightly greater than the length of the injector seat, which not only allows the injector seat to be placed smoothly into the support frame, but also prevents the injector seat from shifting during transportation, so that the injector seat will not fall off the support frame during transportation. The support frame fixedly connected to the bottom of the support frame plays a supporting role, increasing the stability of the support frame, preventing the support frame from shaking when moving, and thus preventing the injector seat on the support frame from shifting.
[0027] B. In this invention, after the injector seat is placed into the material support frame, the servo motor drives the lower transmission shaft to rotate, thereby causing the conveyor belt to move. The servo motor controls the lower transmission shaft to rotate in the opposite direction, and the conveyor belt moves in the opposite direction synchronously, while the conveyor belt synchronously drives the two actuating plates to move. The two actuating plates drive the entire horizontal feeding assembly to move towards the vertical feeding assembly by actuating the support frame. When the horizontal feeding assembly moves, the lower and upper auxiliary rods on the support frame can provide support and prevent the support frame from tilting. In addition, the rollers at both ends of the lower and upper auxiliary rods roll in the first and second grooves respectively, in accordance with the moving speed of the horizontal feeding assembly, making the horizontal feeding assembly move more smoothly and reducing the pressure when the two actuating plates drive the horizontal feeding assembly to move.
[0028] C. In this invention, while the transverse feeding assembly moves laterally towards the vertical feeding assembly, the conveyor belt simultaneously drives the vertical feeding assembly to move upward. When the vertical feeding assembly and the transverse feeding assembly intersect, the fixing frame of the vertical feeding assembly enters the inner side of the material support frame of the transverse feeding assembly. At this time, the injector seat on the material support frame contacts the rotating baffle mechanism under the drive of the material support frame. As the injector seat moves further laterally, the injector seat will press down on and block the baffle plate of the baffle mechanism, causing the baffle plate to rotate around the connecting shaft. At this time, the torsion spring will generate elastic force to store energy; the injector seat... After passing the stop mechanism, the pressure on the stop lever disappears, and the elastic force generated by the torsion spring controls the stop lever to quickly return to its original position, allowing it to re-engage with the limit plate. At this point, the injector seat has moved onto the fixed frame. Once the injector seat is on the fixed frame, the stop mechanism can block it, limiting its range of motion and preventing it from falling off the fixed frame due to excessive displacement. The limit plate can also block the range of motion of the stop lever, ensuring that it rotates within a limited range, allowing the stop mechanism to effectively limit the injector seat's movement.
[0029] D. In this invention, after the injector seat moves onto the vertical feeding assembly, the vertical feeding assembly continues to move upward under the drive of the conveyor belt until it reaches the top of the conveyor belt. At this time, the vertical feeding assembly is close to the discharge port, and the operator can take the injector seat off the fixed frame through the discharge port. The inlet protective plate of the inlet and the outlet protective plate of the outlet can limit the range of motion of the operator when placing or picking up the injector seat, so that the operator's hands and arms will not accidentally touch the moving parts inside the equipment, and prevent the moving parts from causing injury to the operator.
[0030] E. In this invention, after the injector seat is transported, the servo motor controls the conveyor belt to move forward through the lower transmission shaft. While the conveyor belt moves, it drives the vertical feeding component to move downward, and the two actuating plates drive the horizontal feeding component to move towards the feed inlet until the vertical and horizontal feeding components move to their initial positions and stop. At this time, the operator can place the injector seat into the support frame again from the feed inlet to carry out the next injector seat transport operation. When the vertical feeding component moves vertically, the two limiting posts move synchronously in the two limiting grooves. The two limiting grooves and the two limiting posts ensure the stability of the vertical feeding component while ensuring normal movement of the vertical feeding component and prevent excessive shaking of the vertical feeding component.

[0049] Please see Figure 1-16 A keyway machining device for injector seats includes a conveyor belt 1, which is in the form of... The conveyor belt 1 has an upper drive shaft 2 connected to its top inner side and a lower drive shaft 7 connected to its bottom inner side. A middle drive shaft 9 is connected to the inner side of the protruding part of the conveyor belt 1 away from the lower drive shaft 7. The top of the protruding part of the conveyor belt 1 near the lower drive shaft 7 is in contact with the upper guide shaft 3, and the bottom is in contact with the lower guide shaft 8. A vertical feeding assembly 4 is provided above the upper guide shaft 3 and is fixedly connected to the conveyor belt 1. Two actuating plates 6 are provided above the middle drive shaft 9, and the bottoms of both actuating plates 6 are fixedly connected to the conveyor belt 1 by bolts. A transverse feeding assembly 5 is provided between the two conveyor belts 1.
[0050] By adopting the above technical solution, the worker first places the injector seat to be processed onto the support frame 505 of the transverse feeding assembly 5 through the feed port. The support frame 505 is U-shaped and has a support plate welded to its inner side to support the injector seat. The inner length of the support frame 505 is slightly greater than the length of the injector seat, which not only allows the injector seat to be placed smoothly into the support frame 505, but also prevents the injector seat from shifting during transportation, so that the injector seat will not fall off the support frame 505 during transportation. The support frame 501 fixedly connected to the bottom of the support frame 505 plays the role of supporting the support frame 505, increasing the stability of the support frame 505, preventing the support frame 505 from shaking when moving, and thus preventing the injector seat on the support frame 505 from shifting.
[0051] In this embodiment, the vertical feeding assembly 4 includes a fixed frame 401, on which two connecting ribs 402 are symmetrically welded, and both connecting ribs 402 are fixedly connected to the conveyor belt 1 by bolts; a rotating blocking mechanism 405 is provided on the inner side of the fixed frame 401 near the horizontal feeding assembly 5; the rotating blocking mechanism 405 includes a connecting shaft 4052, both ends of which are rotatably connected to the fixed frame 401; a torsion spring 405 is sleeved on the connecting shaft 4052. 3. Both ends of the torsion spring 4053 are fixedly connected to the fixing frame 401, and both ends of the torsion spring 4053 are spiral and the middle is cylindrical; a baffle plate 4051 is welded to the middle of the connecting shaft 4052, and the bottom of the baffle plate 4051 away from the transverse feeding assembly 5 is in contact with the middle part of the torsion spring 4053; the bottom of the baffle plate 4051 near the transverse feeding assembly 5 is in contact with the limiting plate 4054, and both ends of the limiting plate 4054 are welded to the fixing frame 401;
[0052] The two actuating plates 6 are respectively attached to the bottom sides of the support frame 501, and the width of the two support frames 501 is smaller than the width of the support frame 501.
[0053] The two connecting ribs 402 are fixedly connected to the side of the conveyor belt 1 near the transverse feeding assembly 5; the length of the conveyor belt 1 above the protrusion is the same as the length of the protrusion of the conveyor belt 1.
[0054] As the transverse feeding assembly 5 moves laterally toward the vertical feeding assembly 4, the conveyor belt 1 simultaneously drives the vertical feeding assembly 4 to move upward. When the vertical feeding assembly 4 and the transverse feeding assembly 5 intersect, the fixing frame 401 of the vertical feeding assembly 4 enters the inner side of the material support frame 505 of the transverse feeding assembly 5. At this time, the injector seat on the material support frame 505 contacts the rotating baffle mechanism 405 under the drive of the material support frame 505. As the injector seat moves further laterally, the injector seat will press down on the baffle plate 4051 of the baffle mechanism 405, causing the baffle plate 4051 to rotate around the connecting shaft 4052. At this time, the torsion spring 4053 will generate elastic energy storage; the injector seat passes through the baffle mechanism 405. Afterwards, the pressure on the stop plate 4051 also disappears, and the elastic force generated by the torsion spring 4053 will control the stop plate 4051 to quickly reset, allowing the stop plate 4051 to once again adhere to the limit plate 4054. At this time, the injector seat has moved onto the fixed frame 401. After the injector seat moves onto the fixed frame 401, the stop mechanism 405 can block the injector seat, limit the range of motion of the injector seat, and prevent the injector seat from falling off the fixed frame 401 due to excessive displacement. The limit plate 4054 can block the range of motion of the stop plate 4051, so that the stop plate 4051 always rotates within a limited range, allowing the stop mechanism 405 to normally play the role of limiting the displacement of the injector seat.
[0055] In this embodiment, the transverse feeding assembly 5 includes a support frame 501, the top of which is fixedly connected to a material support frame 505 by bolts; the lower end of the support frame 501 is fixedly connected to a lower auxiliary rod 502, and the middle is fixedly connected to an upper auxiliary rod 503; both ends of the lower auxiliary rod 502 and the upper auxiliary rod 503 are rotatably connected to rollers 504.
[0056] The outer side of the conveyor belt 1 is provided with a housing 10, and the inner walls of both sides of the housing 10 are provided with a first groove 11 and a second groove 12; the two ends of the upper auxiliary rod 503 are slidably connected to the two first grooves 11 through rollers 504 respectively; the two ends of the lower auxiliary rod 502 are slidably connected to the two second grooves 12 through rollers 504 respectively.
[0057] Both ends of the upper drive shaft 2, upper guide shaft 3, lower guide shaft 8 and middle drive shaft 9 are rotatably connected to the inner wall of the chassis 10; one end of the lower drive shaft 7 is rotatably connected to the inner wall of the chassis 10, and the other end is fixedly connected to the output shaft of the servo motor 16, which is fixedly connected to the bottom inner side of the chassis 10 by bolts.
[0058] The chassis 10 has a heat dissipation hole 17 on the side near the servo motor 16, and the position of the heat dissipation hole 17 corresponds to the position of the servo motor 16.
[0059] By adopting the above technical solution, after the injector seat is placed into the material support frame 505, the servo motor 16 drives the lower transmission shaft 7 to rotate, thereby moving the conveyor belt 1. The servo motor 16 controls the lower transmission shaft 7 to rotate in the opposite direction, and the conveyor belt 1 moves in the opposite direction synchronously, and the conveyor belt 1 drives the two actuating plates 6 to move synchronously. The two actuating plates 6 drive the transverse feeding assembly 5 to move in the direction of the vertical feeding assembly 4 by actuating the support frame 501. When the transverse feeding assembly 5 moves, the lower auxiliary rod 502 and the upper auxiliary rod 503 on the support frame 501 can play a supporting role to prevent the support frame 501 from tilting. In addition, the rollers 504 at both ends of the lower auxiliary rod 502 and the upper auxiliary rod 503 roll in the first groove 11 and the second groove 12 respectively in accordance with the moving speed of the transverse feeding assembly 5, making the transverse feeding assembly 5 move more smoothly and reducing the pressure when the two actuating plates 6 drive the transverse feeding assembly 5 to move.
[0060] In this embodiment, the chassis 10 is provided with two symmetrical limiting grooves 15 at one end near the vertical feeding component 4; the fixed frame 401 is provided with two symmetrical limiting posts 403 at one end away from the rotating blocking mechanism 405, and the two limiting posts 403 are located inside the two limiting grooves 15 respectively; the other ends of the two limiting posts 403 are each provided with a baffle 404, and the two baffles 404 are located outside the chassis 10.
[0061] By adopting the above technical solution, after the injector seat is transported, the servo motor 16 controls the conveyor belt 1 to move forward through the lower transmission shaft 7. While the conveyor belt 1 moves, it drives the vertical feeding component 4 to move downward. The two actuating plates 6 drive the horizontal feeding component 5 to move towards the feed port until the vertical feeding component 4 and the horizontal feeding component 5 move to their initial positions and stop. At this time, the operator can place the injector seat into the support frame 505 again from the feed port to carry out the next injector seat transportation work. When the vertical feeding component 4 moves vertically, the two limiting posts 403 move synchronously in the two limiting grooves 15. The two limiting grooves 15 and the two limiting posts 403 ensure the stability of the vertical feeding component 4 while ensuring the normal movement of the vertical feeding component 4, and prevent the vertical feeding component 4 from shaking excessively.
[0062] In this embodiment, the top of the chassis 10 is provided with a feed inlet and a discharge outlet, wherein the feed inlet is located above the horizontal feeding assembly 5 and the discharge outlet is located above the vertical feeding assembly 4; a feed protection plate 13 is welded to the inner side of the feed inlet, the material support frame 505 of the horizontal feeding assembly 5 is located inside the feed protection plate 13, and the feed protection plate 13 has an opening at one end near the vertical feeding assembly 4 for the material support frame 505 to pass through; a discharge protection plate 14 is welded to the inner side of the discharge outlet, and the inner dimension of the discharge protection plate 14 is larger than the dimension of the fixing frame 401.
[0063] By adopting the above technical solution, after the injector seat moves onto the vertical feeding assembly 4, the vertical feeding assembly 4 continues to move upward under the drive of the conveyor belt 1 until it reaches the top of the conveyor belt 1. At this time, the vertical feeding assembly 4 is close to the discharge port, and the operator can take out the injector seat from the fixed frame 401 through the discharge port. The feed protection plate 13 of the feed inlet and the discharge protection plate 14 of the discharge port can limit the range of motion of the operator when placing or picking up the injector seat, so that the operator's hands and arms will not accidentally touch the moving parts inside the equipment, and prevent the moving parts from causing injury to the operator.
[0064] A method for machining a keyway for an injector seat includes the following steps:
[0065] Step 1: Placing the injector seat. First, the worker places the injector seat to be processed onto the support frame 505 of the transverse feeding assembly 5 through the feed inlet. The support frame 505 is U-shaped and has a support plate welded to its inner side to support the injector seat. The inner length of the support frame 505 is slightly longer than the length of the injector seat, which allows the injector seat to be placed smoothly into the support frame 505 and prevents the injector seat from shifting during transportation, so that the injector seat will not fall off the support frame 505 during transportation. The support frame 501 fixedly connected to the bottom of the support frame 505 plays a role in supporting the support frame 505, increasing the stability of the support frame 505, preventing the support frame 505 from shaking when moving, and thus preventing the injector seat on the support frame 505 from shifting.
[0066] Step 2: Lateral transport of the injector seat. After placing the injector seat into the material support frame 505, the servo motor 16 drives the lower drive shaft 7 to rotate, causing the conveyor belt 1 to move. The servo motor 16 controls the lower drive shaft 7 to rotate in the opposite direction, and the conveyor belt 1 moves in the opposite direction synchronously, and the conveyor belt 1 synchronously drives the two actuating plates 6 to move. The two actuating plates 6 drive the lateral feeding assembly 5 to move in the direction of the vertical feeding assembly 4 by actuating the support frame 501. When the lateral feeding assembly 5 moves, the lower auxiliary rod 502 and the upper auxiliary rod 503 on the support frame 501 can provide support and prevent the support frame 501 from tilting. In addition, the rollers 504 at both ends of the lower auxiliary rod 502 and the upper auxiliary rod 503 roll in the first groove 11 and the second groove 12 respectively in accordance with the moving speed of the lateral feeding assembly 5, making the lateral feeding assembly 5 move more smoothly and reducing the pressure when the two actuating plates 6 drive the lateral feeding assembly 5 to move.
[0067] Step 3: Injector seat repositioning. As the transverse feeding assembly 5 moves laterally toward the vertical feeding assembly 4, the conveyor belt 1 simultaneously drives the vertical feeding assembly 4 upwards. When the vertical feeding assembly 4 and the transverse feeding assembly 5 intersect, the fixing frame 401 of the vertical feeding assembly 4 enters the inner side of the material support frame 505 of the transverse feeding assembly 5. At this time, the injector seat on the material support frame 505 contacts the rotating baffle mechanism 405 under the influence of the material support frame 505. As the injector seat moves further laterally, it presses against and down the baffle plate 4051 of the baffle mechanism 405, causing the baffle plate 4051 to rotate around the connecting shaft 4052. At this time, the torsion spring 4053 generates elastic energy; the injector seat passes through the baffle... After the feed mechanism 405 is activated, the pressure on the stop plate 4051 also disappears. The elastic force generated by the torsion spring 4053 will control the stop plate 4051 to quickly reset, allowing the stop plate 4051 to re-engage with the limit plate 4054. At this time, the injector seat has moved onto the fixed frame 401. After the injector seat moves onto the fixed frame 401, the stop mechanism 405 can block the injector seat, limiting the range of motion of the injector seat and preventing the injector seat from falling off the fixed frame 401 due to excessive displacement. The limit plate 4054 can block the range of motion of the stop plate 4051, allowing the stop plate 4051 to always rotate within a limited range, so that the stop mechanism 405 can normally play the role of limiting the displacement of the injector seat.
[0068] Step four: Vertical transport of the injector seat. After the injector seat is moved onto the vertical feeding assembly 4, the vertical feeding assembly 4 continues to move upward under the drive of the conveyor belt 1 until it reaches the top of the conveyor belt 1. At this time, the vertical feeding assembly 4 is close to the discharge port, and the operator can take out the injector seat from the fixed frame 401 through the discharge port. The inlet protective plate 13 and the outlet protective plate 14 can limit the range of motion of the operator when placing or picking up the injector seat, so that the operator's hands and arms will not accidentally touch the moving parts inside the equipment, and prevent the moving parts from causing injury to the operator.
[0069] Step 5, Reset. After the injector seat is transported, the servo motor 16 controls the conveyor belt 1 to move forward through the lower transmission shaft 7. As the conveyor belt 1 moves, it drives the vertical feeding assembly 4 to move downward. The two actuating plates 6 drive the horizontal feeding assembly 5 to move towards the feed inlet until the vertical feeding assembly 4 and the horizontal feeding assembly 5 move to their initial positions and stop. At this time, the operator can place the injector seat into the support frame 505 again from the feed inlet to carry out the next injector seat transport operation. When the vertical feeding assembly 4 moves vertically, the two limiting posts 403 move synchronously in the two limiting grooves 15. The two limiting grooves 15 and the two limiting posts 403 ensure the stability of the vertical feeding assembly 4 while ensuring normal movement of the vertical feeding assembly 4 and prevent excessive shaking of the vertical feeding assembly 4.

7. A processing method using the keyway machining equipment for injector seats according to any one of claims 1-6, characterized in that: Includes the following steps: Step 1: Place the injector seat. First, the worker places the injector seat to be processed onto the material support frame (505) of the horizontal feeding assembly (5) through the feed port. The material support frame (505) is U-shaped and the inner side of the material support frame (505) is welded with a support plate, which can support the injector seat. Step 2: Laterally transport the injector seat. After placing the injector seat into the material rack (505), the servo motor (16) drives the lower drive shaft (7) to rotate, causing the conveyor belt (1) to move. The servo motor (16) controls the lower drive shaft (7) to rotate in the opposite direction, and the conveyor belt (1) moves in the opposite direction synchronously. The conveyor belt (1) also drives the two actuating plates (6) to move synchronously. The two actuating plates (6) drive the lateral feeding assembly (5) to move vertically by actuating the support frame (501). The feeding assembly (4) moves in the direction of movement; when the transverse feeding assembly (5) moves, the lower auxiliary rod (502) and the upper auxiliary rod (503) on the support frame (501) can provide support and prevent the support frame (501) from tilting; in addition, the rollers (504) at both ends of the lower auxiliary rod (502) and the upper auxiliary rod (503) roll in the first groove (11) and the second groove (12) respectively in coordination with the moving speed of the transverse feeding assembly (5); Step 3: The injector seat is repositioned. While the transverse feeding assembly (5) moves laterally towards the vertical feeding assembly (4), the conveyor belt (1) simultaneously drives the vertical feeding assembly (4) upwards. When the vertical feeding assembly (4) and the transverse feeding assembly (5) intersect, the fixing frame (401) of the vertical feeding assembly (4) enters the inner side of the material support frame (505) of the transverse feeding assembly (5). At this time, the injector seat on the material support frame (505) contacts the rotating baffle mechanism (405) under the action of the material support frame (505). As the injector seat moves further laterally, the injector seat... The baffle plate (4051) of the baffle mechanism (405) will be pressed down and pushed up, so that the baffle plate (4051) rotates around the connecting shaft (4052) as the center. At this time, the torsion spring (4053) will generate elastic energy. After the injector seat passes through the baffle mechanism (405), its pressure on the baffle plate (4051) will also disappear. The elastic force generated by the torsion spring (4053) will control the baffle plate (4051) to quickly reset, so that the baffle plate (4051) will be in contact with the limit plate (4054) again. At this time, the injector seat has moved onto the fixed frame (401). Step 4: Vertical transport of the injector seat. After the injector seat is moved onto the vertical feeding assembly (4), the vertical feeding assembly (4) continues to move upward under the drive of the conveyor belt (1) until it reaches the top of the conveyor belt (1). At this time, the vertical feeding assembly (4) is close to the discharge port, and the staff can take out the injector seat on the fixed frame (401) through the discharge port. Step 5, Reset. After the fuel injector seat is transported, the servo motor (16) controls the conveyor belt (1) to move forward through the lower transmission shaft (7). While the conveyor belt (1) moves, it drives the vertical feeding component (4) to move downward. The two actuating plates (6) drive the horizontal feeding component (5) to move towards the feed port until the vertical feeding component (4) and the horizontal feeding component (5) move to the initial position and stop. At this time, the staff can place the fuel injector seat into the material rack (505) again from the feed port to carry out the next fuel injector seat transport work. When the vertical feeding component (4) moves vertically, the two limit posts (403) move synchronously in the two limit grooves (15).
