[0002] In the manufacturing process of automobiles, mudguards are a component of the wheel well of cars, motorcycles, or other vehicles. Their main purpose is to prevent the spinning tires from throwing sand, mud, rocks, liquids, and other road debris into the air. Mudguards are typically rigid and can be made of alloy, high-quality plastic, or rubber.

[0003] When installing mudguards onto a car, they need to be secured. Currently, the method used is to fix a connecting nozzle to the mudguard, which passes through a connecting hole in the mudguard and is then fixed to the car with fasteners. This invention provides a tooling for manufacturing car mudguards to process and secure the connecting nozzle of the car mudguard. Summary of the Invention

[0004] To address the aforementioned problems in existing technologies, this invention provides a tooling solution for manufacturing automotive mudguards. The first and second workstations of this invention can simultaneously process two connecting nozzles, and after one process is completed, the connecting nozzle to be processed can be quickly moved to another workstation, thereby improving processing efficiency. Existing connecting nozzles, due to the lack of clamping and positioning points on most workpieces, present complex fixture designs. This invention uses a core clamp to hold workpieces like connecting nozzles, simplifying the fixture design and solving the problems of positioning and clamping difficulties.

The straight line where the two positioning pins are connected is perpendicular to the straight line where the two clamping structures are connected. The end of the connecting nozzle to be processed near the support plate is provided with a positioning hole corresponding to the positioning pin.

[0020] Furthermore, the clamping structure includes a pressure plate, a connecting block, and a hinge plate.

Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

[0032] A tooling for producing automobile mudguards, such as Figure 1 and Figure 2 As shown, it includes:

[0033] Mounting platform 1, with mounting plate 11 mounted on its surface;

[0034] The first station 3 is located on the mounting plate 11 and is used to clamp the connecting nozzle 2 to be processed.

[0035] A second station 4 is located downstream of the first station 3, and the second station 4 is used to receive and clamp the connecting nozzle 2 from the first station 3; and

[0036] The drilling mechanism 5, mounted on the mounting platform 1, is used to process the connecting nozzle 2 from the second station 4.

[0037] According to a specific embodiment of the present invention, the mounting platform 1 is an integral part of the machine tool equipment. A mounting plate 11 is fixed horizontally on the upper part of the mounting platform 1. A first workstation 3 and a second workstation 4 are arranged adjacent to each other on the mounting plate 11. The connector 2 to be processed has a cylindrical structure with an elliptical plate at one end. The first workstation 3 is used to process the end face of the elliptical plate. The first workstation 3 includes at least one pair of core clamps 31, which can be commercially available. After the connector 2 is processed at the first workstation 3, it is flipped and fixed by the second workstation 4. The second workstation 4 is used to process the other side of the elliptical plate of the connector 2. This embodiment uses core clamps 31 to hold workpieces like the connector 2, which not only simplifies the fixture design but also solves the problems of positioning and clamping difficulties.

[0038] Furthermore, such as Figure 3 As shown, the punching mechanism 5 includes,

[0039] Support base 51, the support base 51 is equipped with clamping component 52, the clamping component 52 can be used to clamp the connecting nozzle 2;

[0040] A drilling assembly is installed on the support base 51. The drilling assembly includes a drilling base plate 53, a drill gun 54 installed on the drilling base plate 53, and a limiting structure 55. One end of the drilling base plate 53 is rotatably installed on the upper surface of the support base 51. An angle scale is provided on the upper surface of the support base 51. The limiting structure 55 is installed on the other end of the drilling base plate 53. The limiting structure 55 is used to restrict the rotation of the drilling base plate 53.

[0041] Drilling is the third step in processing the connector nozzle 2. After the second station 4 finishes processing the other side of the elliptical plate of the connector nozzle 2, it is transferred to the drilling mechanism 5. The drilling mechanism 5 clamps and fixes the connector nozzle 2, which is simple to operate, reliable, and efficient. The drilling assembly is installed on the support base 51. The upper surface of the support base 51 is provided with angle scales. The other end of the drilling base plate 53 is equipped with a limiting structure 55, which is used to limit the rotation of the drilling base plate 53. The upper surface of the fan-shaped plate of the support base 51 is provided with angle scales to determine the rotation angle of the drill gun 54, so that the drill gun 54 can drill holes of different angles in the circumference of the connector nozzle 2 being processed. The drilling mechanism 5 is installed on the mounting table 1 of the present invention, which is used to drill holes in the circumferential surface of the connector nozzle 2 from the second station 4, thereby reducing the overall weight of the connector nozzle 2.

[0042] Furthermore, the clamping component 52 includes a limiting frame, a first clamping block 522, and a driving screw 523. The middle of the limiting frame is for the connecting nozzle 2 to be processed to pass through. Two parallel first clamping blocks 522 are fixed on one side of the limiting frame. The driving screw 523 is threadedly connected to one side of the limiting frame. A nozzle clamping component is rotatably connected to the end of the driving screw 523. The nozzle clamping component is slidably engaged with the limiting frame, and the nozzle clamping component and the first clamping block 522 are arranged opposite to each other. The driving screw 523 is used to drive the nozzle clamping component to move along the limiting frame to clamp the connecting nozzle 2 to be processed.

[0043] According to a specific embodiment of the present invention, this embodiment provides a specific structure of a clamping component 52. By operating the drive screw 523, the first clamping block 522 is moved along the direction set by the limiting frame. The first clamping block 522 cooperates with the mouth clamping component to clamp and fix the connecting mouth 2.

[0044] Furthermore, the limiting frame includes two parallel guide rods 521 and two parallel vertical plates 524. The drive screw 523 is threadedly connected to one of the vertical plates 524. The first clamping block 522 is fixed to both sides of the other vertical plate 524. The ends of the two guide rods 521 are respectively fixed to one side of the end of one vertical plate 524. The guide rods 521 are horizontally arranged. The guide rods 521 are horizontally arranged, and the two vertical plates 524 are vertically arranged. The two vertical plates 524 are located on both sides of the connecting mouth 2, and one of the vertical plates 524 is fixed to the support base 51.

[0045] Furthermore, the mouthpiece clamping component includes two parallel second clamping blocks 56 and a moving plate 57. The two second clamping blocks 56 are respectively located on both sides of the moving plate 57, and the second clamping blocks 56 are fixed together by a plurality of connecting rods. The second clamping blocks 56 are respectively located on both sides of the two first clamping blocks 522, and the guide rod 521 is disposed through the moving plate 57. According to a specific embodiment of the present invention, a "V"-shaped groove is formed on the opposite side of the first clamping block 522 and the second clamping block 56. The "V"-shaped groove is used to accommodate the connecting mouthpiece 2. The second clamping blocks 56 are respectively located on both sides of the two first clamping blocks 522, which makes the connecting mouthpiece 2 more stably fixed.

[0046] Furthermore, such as Figure 4 As shown, the second workstation 4 includes a support 41 for placing the connector 2 to be processed, a hydraulic cylinder 42, and a clamping structure 43. The support 41 is fixed on the mounting plate 11. The hydraulic cylinders 42 are symmetrically arranged on both sides of the support 41 and are mounted on the mounting plate 11. Each hydraulic cylinder 42 has its output end connected to a clamping structure 43. The clamping structures 43 extend close to each other to the top of the support 41 to clamp the connector 2 to be processed.

[0047] According to a specific embodiment of the present invention, the support portion 41 of the second station 4 is located in the middle of two hydraulic cylinders 42, the line connecting the two hydraulic cylinders 42 is in the Y-axis direction, and the line connecting the first station 3 and the second station 4 is in the X-axis direction. The two pairs of core clamps 31 of the first station 3 move along the Y-axis direction to clamp and fix the connecting nozzle 2 to be processed. The support portion 41 of the second station 4 is used to place the connecting nozzle 2 to be processed and to provide positioning. The hydraulic cylinders 42 are used to provide power to the clamping structure 43, and the clamping structure 43 is used to clamp and fix the connecting nozzle 2 to be processed.

[0048] Furthermore, the first workstation 3 includes at least one pair of core clamps 31, which are used to clamp the connecting nozzle 2 to be processed.

[0049] Furthermore, a support plate is fixedly installed on the support part 41. The support plate is an elliptical plate structure that matches one end of the connecting nozzle 2 to be processed. Each support plate is equipped with two positioning pins 411. The line connecting the two positioning pins 411 is perpendicular to the line connecting the two clamping structures 43. The end of the connecting nozzle 2 to be processed near the support plate is provided with a positioning hole corresponding to the positioning pin 411.

[0050] Furthermore, the clamping structure 43 includes a pressure plate 431, a connecting block 432, and a hinge plate 433. The connecting block 432 is fixed on the hydraulic cylinder 42. A hinge plate 433 is hinged to both sides of the connecting block 432. The ends of the two hinge plates 433 away from the hinge block are both hinged to the middle of the pressure plate 431. One end of the pressure plate 431 is hinged to the output end of the hydraulic cylinder 42.

[0051] Furthermore, the pressure plates 431 of each of the aforementioned clamping structures 43 are staggered. That is, the lines on which the pressure plates 431 lie are parallel to each other but do not coincide, so that when the pressure plates 431 press on the upper part of the connecting nozzle 2, the pressure can be more balanced.

[0052] Mounting platform 1 has several parallel mounting slots 12, each with a T-shaped cross-section. Fastening bolts are installed within the mounting slots 12 and are threadedly connected to the mounting plate 11. Limiting pins are also fixed within the mounting slots 12, extending into limiting holes in the mounting plate 11. As the limiting pins move along the mounting slots 12, the position of the mounting plate 11 on the mounting platform 1 can be changed.

[0053] The first station 3 and the second station 4 of this invention can process two connectors 2 simultaneously, and after one process is completed, the connector 2 to be processed can be quickly moved to another station, thereby improving processing efficiency. Existing connectors 2, due to the lack of clamping positioning points in most workpieces, make the design of processing fixtures quite complex. This invention uses a core clamp 31 to hold workpieces like connectors 2, which not only simplifies the fixture design but also solves the problems of positioning and clamping difficulties.

[0054] The present invention has a drilling mechanism 5 installed on the mounting table 1, which is used to drill holes in the circumferential surface of the connecting nozzle 2 from the second work station 4, thereby reducing the overall weight of the connecting nozzle 2. The drilling mechanism 5 can also clamp and fix the connecting nozzle 2, which is simple to operate, reliable to fix, and has high working efficiency. In some embodiments, a drilling assembly is installed on the support base 51. The drilling assembly includes a drilling base plate 53, a drill gun 54 installed on the drilling base plate 53, and a limiting structure 55. One end of the drilling base plate 53 is rotatably installed on the upper surface of the support base 51. An angle scale is provided on the upper surface of the support base 51. The limiting structure 55 is installed on the other end of the drilling base plate 53. The limiting structure 55 is used to restrict the rotation of the drilling base plate 53. The upper surface of the fan-shaped plate of the support base 51 of the present invention is provided with an angle scale to determine the rotation angle of the drill gun 54, so that the drill gun 54 can drill holes at different angles in the circumferential direction of the connected nozzle 2 being processed.
