Description

Technical Field

[0001] This utility model belongs to the field of automotive dust cover processing technology, specifically relating to a drilling tool for processing automotive dust covers. Background Technology

[0002] The manufacturing of automotive dust covers primarily involves using a series of precision processing techniques to create protective components from the required materials. Dust covers protect automotive parts from dust, dirt, and moisture, preventing them from entering critical mechanical components and extending their lifespan. The manufacturing process for automotive dust covers includes multiple stages such as mold design, material selection, injection molding, stamping, drilling, and surface treatment. Drilling fixtures are typically used to assist in the drilling process.

[0003] Existing drilling fixtures typically use only one drill bit for drilling, processing only one hole at a time. For dust covers that require mass production, each hole needs to be drilled one by one, resulting in significant waste of working time and an inability to process multiple holes simultaneously, leading to slower processing speeds and reduced overall production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a drilling fixture for processing automotive dust covers, which can achieve simultaneous multi-hole processing, greatly improve production efficiency, and save processing time.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A drilling fixture for machining automotive dust covers includes a drilling table, a support, a vertical slot, a threaded rod, a sliding block, a rotary motor, and a structural box. The support is fixedly installed on the rear side of the top of the drilling table. The vertical slot is formed on the front side of the support. One end of the threaded rod is connected to the bottom of the inner wall of the vertical slot via a bearing, and the other end of the threaded rod extends through to the top of the support. The sliding block is threadedly connected to the surface of the threaded rod and slidably connected to the inside of the vertical slot. The rotary motor is fixedly installed on the top of the support, and the output end of the rotary motor at its bottom is fixedly connected to the top end of the threaded rod. The structural box is fixedly installed on the front side of the sliding block, and a linkage drilling mechanism is provided inside the structural box. The drilling mechanism includes vertical plates, drill rods, bevel gears, rotating rods, output wheels, and a servo motor. Two vertical plates are installed inside the structural box. Two drill rods are rotatably connected to the interior of the two vertical plates, with their bottom ends extending to the bottom of the structural box. Two bevel gears are fixedly connected to the top ends of the two drill rods. One end of the rotating rod is connected to one side of the inner wall of the structural box via a bearing, and the other end extends through to the outside of the structural box. Two output wheels are sleeved on the surface of the rotating rod, and are meshed with one side of the two bevel gears. The servo motor is fixedly installed on one side of the structural box and fixedly connected to one end of the rotating rod.

[0007] Preferably, a guide bar is fixedly connected to the surface of the rotating rod, and a groove is provided on the inner wall of the output wheel on the left side to cooperate with the guide bar.

[0008] Preferably, a lead screw is rotatably connected to the outer side of the left vertical plate, the other end of the lead screw extends through to the outer side of the structural box, and the lead screw is threaded to the inner wall of the structural box.

[0009] Preferably, sliders are fixedly connected to the front and rear sides of the vertical plate on the left, and guide grooves that cooperate with the sliders are provided on the front and rear sides of the inner wall of the structural box.

[0010] Preferably, one end of the lead screw is fixedly connected to an adjustment knob, which is round in shape.

[0011] Preferably, the bottom of the structure box is provided with a horizontal groove, and the drill rod on the left side is slidably disposed inside the horizontal groove.

[0012] Preferably, a protective box is installed on one side of the structural box, and the servo motor is located inside the protective box.

[0013] The technical effects achieved by this utility model are as follows:

[0014] In this invention, when drilling a workpiece, the workpiece is first placed and positioned on the drilling table. Then, a servo motor is activated, which drives a rotating rod to rotate. The rotating rod then drives two output wheels to rotate, which in turn drives two meshing bevel gears to rotate. The rotation of the two meshing bevel gears simultaneously drives two drill rods to rotate. Subsequently, a rotary motor is activated, which drives a threaded rod to rotate. The rotation of the threaded rod causes a threaded sliding block to slide downward inside the vertical groove. The downward sliding of the sliding block causes the structural box to move downward, which in turn causes the two drill rods to move downward, thus simultaneously machining multiple holes in the workpiece on the drilling table. Compared to the traditional method of drilling one hole at a time with a single drill bit, this significantly improves production efficiency.

[0015] In this invention, during multi-hole machining, the distance between the two drill rods can be adjusted as needed. Adjusting the drill rod spacing can be achieved by rotating the lead screw using an adjustment knob. The rotation of the lead screw will compress or move the left vertical plate. The movement of the vertical plate simultaneously moves the left output wheel and bevel gear. When the left output wheel moves, it aligns the guide strip with the groove, allowing the output wheel to move parallel to the surface of the rotating rod. As the left vertical plate moves, it drives the left drill rod to move horizontally, thus adjusting the distance between the two drill rods. Adjusting the drill rod distance supports machining different hole spacings, allowing the same tooling to be used for various types of workpieces without needing to change tooling, thereby improving the flexibility of the production line.

Detailed Implementation

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-4 As shown, a drilling fixture for processing automotive dust covers includes a drilling table 1, a bracket 101, a vertical groove 102, a threaded rod 103, a sliding block 104, a rotary motor 105, and a structural box 2. The bracket 101 is fixedly installed on the rear side of the top of the drilling table 1. The vertical groove 102 is formed on the front side of the bracket 101. One end of the threaded rod 103 is connected to the bottom of the inner wall of the vertical groove 102 via a bearing, and the other end of the threaded rod 103 extends through to the top of the bracket 101. The sliding block 104 is threadedly connected to the surface of the threaded rod 103 and slidably connected. Inside the vertical slot 102, a rotating motor 105 is fixedly installed on the top of the bracket 101, and the output end of the rotating motor 105 is fixedly connected to the top of the threaded rod 103. The structural box 2 is fixedly installed on the front side of the sliding block 104, and a linkage drilling mechanism is provided inside the structural box 2. The linkage drilling mechanism includes a vertical plate 201, a drill rod 202, a bevel gear 203, a rotating rod 204, an output wheel 205, and a servo motor 206. Both vertical plates 201 are installed inside the structural box 2, and the two drill rods 202 rotate respectively. Connected to the interior of two vertical plates 201, the bottom ends of two drill rods 202 extend to the bottom of the structure box 2. Two bevel gears 203 are fixedly connected to the top ends of the two drill rods 202. One end of the rotating rod 204 is connected to one side of the inner wall of the structure box 2 via a bearing, and the other end of the rotating rod 204 extends to the outside of the structure box 2. Two output wheels 205 are sleeved on the surface of the rotating rod 204, and the two output wheels 205 are respectively meshed with one side of the two bevel gears 203. The servo motor 206 is fixedly installed in the structure box 2. One side is fixedly connected to one end of the rotating rod 204. With the cooperation of the linkage drilling mechanism, multiple holes can be machined on the workpiece simultaneously through two drill rods 202. Compared with the traditional hole-by-hole machining, the linkage of the two drill rods 202 can complete the machining of multiple holes at one time, thereby shortening the entire machining cycle. Moreover, by adjusting the distance between the two drill rods 202, machining of different hole spacings can be supported, so that the same tooling can be used for a variety of different types of workpieces without the need to change different tooling, thus improving the flexibility of the production line.

[0024] like Figure 2 and Figure 4As shown, a guide bar 301 is fixedly connected to the surface of the rotating rod 204. The inner wall of the left output wheel 205 is provided with a groove 302 that cooperates with the guide bar 301. Through the cooperation of the guide bar 301 and the groove 302, when adjusting the distance between the left drill rod 202 and the right drill rod 202, the output wheel 205 can move parallel to the surface of the rotating rod 204, without affecting the rotation of the rotating rod 204 to drive the output wheel 205 to rotate, thus not affecting the normal operation of the linkage drilling mechanism.

[0025] like Figure 2 As shown, a lead screw 4 is rotatably connected to the outer side of the left vertical plate 201. The other end of the lead screw 4 extends through to the outer side of the structural box 2, and the lead screw 4 is threaded to the inner wall of the structural box 2. When adjusting the distance of the drill rod 202, the vertical plate 201 and the left drill rod 202 can be adjusted by rotating the lead screw 4, making the adjustment process smoother and more precise. Operators can make very fine distance adjustments according to actual needs, improving the accuracy of the operation.

[0026] like Figure 2 and Figure 3 As shown, sliders 501 are fixedly connected to the front and rear sides of the left vertical plate 201. Guide grooves 502 that cooperate with sliders 501 are opened on the front and rear sides of the inner wall of the structure box 2. When adjusting the distance of the drill rods 202, the vertical plate 201 will drive the sliders 501 to slide inside the guide grooves 502, so that the vertical plate 201 can move precisely along the predetermined trajectory during the adjustment process, avoiding possible offset or tilt of the vertical plate 201. This makes the adjustment process more stable and can accurately control the distance between the drill rods 202.

[0027] like Figure 2 As shown, an adjustment knob 6 is fixedly connected to one end of the lead screw 4. The adjustment knob 6 is round. The round design of the adjustment knob 6 allows the operator to finely adjust the position of the lead screw 4 by rotating it. The rotation of the adjustment knob 6 can make the lead screw 4 move smoothly, further improving the precision control during the adjustment process.

[0028] like Figure 2 As shown, a transverse groove 7 is provided at the bottom of the structural box 2. The left drill rod 202 is slidably disposed inside the transverse groove 7. When adjusting the movement of the left drill rod 202, the drill rod 202 will move flexibly inside the transverse groove 7 to prevent insufficient movement space of the drill rod 202 during adjustment, which would cause the left drill rod 202 to collide with the inner wall of the structural box 2 and cause motion interference.

[0029] like Figure 1 and Figure 2As shown, a protective box 8 is installed on one side of the structural box 2. The servo motor 206 is located inside the protective box 8. The protective box 8 can effectively prevent dust, dirt and external debris from entering the servo motor 206, keep the servo motor 206 clean, reduce wear or failure caused by dirt accumulation, and improve the overall reliability of the equipment.

[0030] The working principle of this utility model is as follows: When drilling a workpiece, the workpiece can first be placed on the drilling table 1 and positioned and installed by the fixture inside the drilling table 1. The fixture can be a bench vise type fixture. Then, the servo motor 206 is run. The operation of the servo motor 206 will drive the rotating rod 204 to rotate. The rotation of the rotating rod 204 will drive the two output wheels 205 to rotate. The rotation of the two output wheels 205 will drive the two meshing bevel gears 203 to rotate. The rotation of the two meshing bevel gears 203 will simultaneously drive the two drill rods 202 to rotate. Then, the rotating motor 105 is run and drives the threaded rod 103 to rotate. The rotation of the threaded rod 103 will drive the threaded sliding block 104 to slide downward inside the vertical groove 102. The downward sliding of the sliding block 104 will drive the structure box 2 to move downward. The downward movement of the structure box 2 will drive the two drill rods 202 to move downward, and the workpiece on the drilling table 1 will be processed with multiple holes simultaneously. Compared with the traditional method of drilling one hole at a time with a single drill bit, this method can greatly improve production efficiency.

[0031] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
