Description

Technical Field

[0001] This utility model relates to the field of fender production technology, specifically to a drilling device for fender production that facilitates fixing. Background Technology

[0002] The fender is the outer body panel that covers the wheels. It is named after the shape and position of this part on the old car body, which resembles a bird's wing. According to the installation position, it is divided into front fender and rear fender. The front fender is installed at the front wheel and must ensure the maximum limit space when the front wheel rotates and bounces. Therefore, the designer will use the "wheel bounce diagram" to verify whether the design size of the fender is appropriate according to the selected tire model and size.

[0003] According to announcement number CN 214349763 U, a drilling device for fender production includes: a machine base; a frame: fixedly installed on the machine base; a cylinder: a fixed part fixedly connected to the frame; a moving plate: fixedly connected to the moving part of the cylinder, the cylinder driving the moving plate to move up and down; a mold: located below the moving plate, fixedly installed on the machine base, and having a cavity for accommodating the fender; a drill: fixedly installed on the moving plate for drilling holes in the fender; mounting rods: located on both sides of the drill and installed on the moving plate; and a soft suction cup: fixedly installed on the mounting rods.

[0004] In this device, the fender is placed inside the mold cavity. A cylinder drives a moving plate downwards, causing the drill to bore a hole in the fender. Simultaneously, a mounting rod presses down on the soft suction cup, ensuring tight contact between the suction cup and the fender. This serves two purposes: firstly, it presses and secures the fender; secondly, after drilling, the cylinder moves the moving plate upwards, allowing the soft suction cup to lift the fender out of the mold cavity for easy removal. However, a spring is located above the suction cup, and the spring causes it to wobble during fixing, potentially leading to instability in the fender during drilling. Utility Model Content

[0005] The purpose of this invention is to provide a punching device for fender production that is easy to fix, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for fender production that is easy to fix, including a base, with supporting legs symmetrically fixedly connected to the bottom of the base in the front, back, left and right directions, a clamping and fixing mechanism provided at the bottom of the base, and a drilling mechanism provided at the top of the base near the back.

[0007] The clamping and fixing mechanism includes a U-shaped frame, which is fixedly connected to the bottom of the base. A first hydraulic cylinder is fixedly connected to the bottom of the inner wall of the U-shaped frame. A first lifting plate is fixedly connected to the output end of the first hydraulic cylinder. Slide rods are symmetrically fixedly connected to the left and right sides of the first lifting plate. Hinged frames are symmetrically fixedly connected to the top of the base. Rotating blocks are hinged within the four hinged frames. A fixing plate is fixedly connected to the bottom of the rotating blocks near one end. Rubber clamps are fixedly connected to the bottom of the fixing plates at equal intervals. A placement seat is fixedly connected to the top of the base.

[0008] Preferably, the bottom left and right sides of the base are provided with holes that match the slide rod, and the slide rod is connected to the hole through the surface and slides up and down.

[0009] Preferably, the top ends of the four slide rods are hinged to the other end of the rotating block.

[0010] Preferably, the drilling mechanism includes a fixed frame, which is fixedly connected to the top of the base near the back. A second hydraulic cylinder is fixedly connected to the top of the fixed frame, and a second lifting plate is fixedly connected to the output end of the second hydraulic cylinder. Guide rods are symmetrically fixedly connected to the upper and lower sides of the inner wall of the fixed frame. A servo motor is fixedly connected to the top of the second lifting plate near the front, and a drill bit is fixedly connected to the output end of the servo motor.

[0011] Preferably, the surface of the second lifting plate is located within the fixed frame, and it moves up and down within the fixed frame.

[0012] Preferably, the top of the second lifting plate has a hole near the back that matches the guide rod, and the second lifting plate is slidably connected to the surface of the guide rod through the hole, so that the second lifting plate moves up and down more stably.

[0013] Compared with the prior art, this utility model provides a drilling device for fender production that is easy to fix, and has the following beneficial effects:

[0014] 1. This easy-to-fix fender production drilling device, through a fixing mechanism, uses a first hydraulic cylinder inside a U-shaped frame to drive the first lifting plate to move up and down, which in turn drives the rotating block hinged to the base to perform a lever-like movement through a sliding rod, so that the rubber clamping block at the bottom of the fixing plate tightly fits and clamps the fender. This not only enhances the clamping force, but also reduces damage to the fender surface during clamping through the elasticity of the rubber clamping block, ensuring the accuracy of drilling and the quality of the fender.

[0015] 2. This easy-to-fix fender production drilling device, through the drilling mechanism, uses a second hydraulic cylinder to drive a second lifting plate to move stably up and down within a fixed frame. Combined with a servo motor-driven drill bit, it achieves precise drilling of the fender. The second lifting plate, guided by a guide rod, ensures the smoothness and verticality of its up and down movement, thereby improving the accuracy and consistency of the drilling.

[0025] This utility model provides the following technical solution:

[0026] Example 1

[0027] Please see Figure 1-3 This utility model provides a technical solution: a drilling device for fender production that is easy to fix, including a base 1, with support legs 2 symmetrically fixed to the bottom of the base 1 in the front, back and left and right, a clamping and fixing mechanism 3 provided at the bottom of the base 1, and a drilling mechanism 4 provided at the top of the base 1 near the back.

[0028] The clamping and fixing mechanism 3 includes a U-shaped frame 31, which is fixedly connected to the bottom of the base 1. A first hydraulic cylinder 32 is fixedly connected to the bottom of the inner wall of the U-shaped frame 31. A first lifting plate 33 is fixedly connected to the output end of the first hydraulic cylinder 32. Slide rods 34 are fixedly connected to the left and right sides and front and back of the first lifting plate 33. Hinged frames 35 are fixedly connected to the top of the base 1 on the left and right sides and front and back. Rotating blocks 36 are hinged in the four hinged frames 35. A fixing plate 37 is fixedly connected to the bottom of the rotating block 36 near one end. Rubber clamps 38 are fixedly connected to the bottom of the fixing plate 37 at equal distances front and back. A placement seat 39 is fixedly connected to the top of the base 1.

[0029] The bottom left and right sides of the base 1 have holes that match the slide rod 34, and the slide rod 34 is connected to the hole by sliding up and down through the surface of the slide rod 34.

[0030] The top ends of the four sliding rods 34 are hinged to the other end of the rotating block 36.

[0031] Example 2

[0032] Please see Figure 4-5 Furthermore, based on Example 1, a drilling mechanism 4 was obtained.

[0033] The drilling mechanism 4 includes a fixed frame 41, which is fixedly connected to the top of the base 1 near the back. A second hydraulic cylinder 42 is fixedly connected to the top of the fixed frame 41. A second lifting plate 43 is fixedly connected to the output end of the second hydraulic cylinder 42. Guide rods 44 are symmetrically fixedly connected to the upper and lower sides of the inner wall of the fixed frame 41. A servo motor 45 is fixedly connected to the top of the second lifting plate 43 near the front. A drill bit 46 is fixedly connected to the output end of the servo motor 45.

[0034] The surface of the second lifting plate 43 is located inside the fixed frame 41, and it moves up and down within the fixed frame 41.

[0035] The top of the second lifting plate 43 is provided with a hole that matches the guide rod 44 near the back. The second lifting plate 43 is slidably connected to the surface of the guide rod 44 through the hole, making the up-and-down movement of the second lifting plate 43 more stable.

[0036] In actual operation, when this device is used and it is necessary to fix the fender on the mounting base 39 for drilling, the first hydraulic cylinder 32 is activated, and its output end extends upward, pushing the first lifting plate 33 to rise. The rise of the first lifting plate 33 causes the slide rod 34 to slide upward in the hole at the bottom of the base 1. Since the top of the slide rod 34 is hinged to the other end of the rotating block 36, the rise of the slide rod 34 forces the rotating block 36 to rotate around the hinge frame 35, causing the fixing plate 37 and the rubber clamp 38 to move downward until the rubber clamp 38 is tightly attached to the surface of the fender, achieving a stable clamping of the fender. At this time, the second hydraulic cylinder 42 is in the retracted state, the second lifting plate 43 is located at the highest point in the fixing frame 41, and the servo motor 45 and the drill bit 46 are also in a high position. The second hydraulic cylinder 42 is activated, and its output end extends downward, pushing the second lifting plate 43 along the guide. The rod 44 moves downward, and the descent of the second lifting plate 43 drives the servo motor 45 and the drill bit 46 to descend synchronously until the drill bit 46 contacts the fender surface. At this time, the servo motor 45 is started, and its output end rotates at high speed, driving the drill bit 46 to rotate and perform drilling operations on the fender. After the drilling operation reaches the predetermined depth, the servo motor 45 is turned off, and the rotation of the drill bit 46 is stopped. Then, the second hydraulic cylinder 42 is controlled to retract, driving the second lifting plate 43, the servo motor 45, and the drill bit 46 to rise until the second lifting plate 43 returns to the highest point in the fixed frame 41, completing one drilling cycle. After the drilling operation is completed, the first hydraulic cylinder 32 is controlled to retract, driving the first lifting plate 33 and the slide rod 34 to descend, thereby causing the rotating block 36 to rotate in the opposite direction. The fixed plate 37 and the rubber clamp 38 are lifted, releasing the clamp on the fender, making it easier to remove the processed fender.
