A milling machine for automotive engine parts

Abstract

This utility model relates to the technical field of automotive parts processing, and in particular to a milling machine for automotive engine parts. The machine includes a processing table, with a support frame fixedly connected to the upper surface of the processing table. A slot is formed on the upper surface of the support frame, and a positioning component is fixedly connected to the inner wall of the slot. This milling machine for automotive engine parts, through the coordinated arrangement of the positioning component and the milling component, allows for the positioning and support of tubular parts using a first positioning rod, a second positioning rod, and a support rod. The milling groove on the surface of the support rod, in conjunction with a milling cutter, can mill and groove the surface of the tubular parts. Due to the internal support and blocking effect of the support rod, the surface of the tubular parts, except for the milling groove location, will not deform, improving the milling effect. Furthermore, during reverse milling, a limiting block can lock the grooved position, ensuring that the milling positions at both ends of the part remain consistent.

Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts processing, and in particular to a milling machine for automotive engine parts. Background Technology

[0002] Automotive parts refer to the components that make up the various units of a car as a whole, as well as all consumable materials that serve the car. These include engine parts, transmission parts, braking parts, steering parts, running system parts, electrical instrument parts, body and accessories, and interior and exterior trim. Among these are many tubular parts, which require grooving and milling after production, thus necessitating the use of milling equipment.

[0003] When grooving tubular parts, existing milling equipment typically involves workers manually placing the tubular parts onto a support frame, clamping them with a clamping structure, and then using a hydraulic cylinder to lower the milling assembly to complete the milling process. However, the current positioning structure only ensures that the tubular parts do not wobble or shift during milling. When the milling cutter contacts the tubular parts, there is no internal support structure, which makes the area near the contact point with the milling cutter prone to deformation, thus reducing the milling effect. In addition, both ends of the tubular parts need to be grooved, and existing milling equipment cannot ensure that the grooving positions at both ends of the tubular parts are completely consistent, which can easily lead to errors that affect subsequent processing and assembly operations. Utility Model Content

[0004] The purpose of this utility model is to provide a milling machine for automotive engine parts, in order to solve the problem mentioned in the background art that the existing milling machines rely solely on the clamping structure to ensure the stability of tubular parts, but cannot support the contact position between the tubular parts and the milling cutter, resulting in deformation easily occurring near the contact position between the tubular parts and the milling cutter.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a milling machine for automobile engine parts, including a processing table, a support frame fixedly connected to the upper surface of the processing table, a slot provided on the upper surface of the support frame, a positioning component fixedly connected to the inner wall of the slot, a positioning platform fixedly connected to the upper surface of the processing table, a hydraulic cylinder fixedly connected to the inner top wall of the positioning platform, and a milling component fixedly connected to the output end of the hydraulic cylinder. The positioning component is used to position automotive tubular parts, and the milling component is used to perform milling operations on automotive tubular parts.

[0006] Preferably, the positioning component includes a support plate, and a first positioning frame and a second positioning frame are fixedly connected to the upper surface of the support plate, and arc-shaped grooves are opened at the same position on the upper surfaces of the first positioning frame and the second positioning frame.

[0007] Preferably, a positioning plate is connected to the upper surface of the support plate, a cylinder is fixedly connected to the upper surface of the positioning plate, a U-shaped frame is fixedly connected to the upper surface of the support plate, a limit groove is opened on the left and right inner walls of the U-shaped frame, a locking rod is fixedly connected to the inner wall of the limit groove, a slider is slidably connected to the inner wall of the limit groove, and a movable plate is fixedly connected to the opposite face of the two sliders.

[0008] Preferably, the slider is slidably connected to the surface of the locking rod, and the movable plate is slidably connected to the inner bottom wall of the U-shaped frame. A first positioning rod and a second positioning rod are fixedly connected to the back of the movable plate, and a limit block is fixedly connected to the surface of the second positioning rod.

[0009] Preferably, a milling positioning frame is fixedly connected to the upper surface of the support frame, a fixed platform is fixedly connected to the back of the support frame, and two support rods are fixedly connected to the front of the fixed platform. The surfaces of the two support rods are milled grooves, and the positions of the two support rods correspond to the positions of the first positioning rod and the second positioning rod, respectively.

[0010] Preferably, the milling assembly includes a right-angle bracket, and two stabilizing grooves are formed on the lower surface of the right-angle bracket, the positions of the two stabilizing grooves corresponding to the positions of the two arc-shaped grooves respectively.

[0011] Preferably, a fixed frame is fixedly connected to the lower surface of the right-angle frame, and two servo motors are fixedly connected to the inner wall of the fixed frame. Milling cutters are fixedly connected to the output ends of the two servo motors, and the positions of the milling cutters correspond to the positions of the milling grooves.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This automobile engine parts milling equipment, through the cooperative arrangement of positioning components and milling components, can use a first positioning rod, a second positioning rod, and a support rod to position and support tubular parts during use. The milling groove on the surface of the support rod can cooperate with the milling cutter to mill and groove the surface of the tubular parts. Due to the internal support and blocking effect of the support rod, the surface of the tubular parts will not deform except at the milling groove position, thus improving the milling effect of the parts. Furthermore, when milling in the reverse direction, the limiting block on the surface of the second positioning rod can lock the grooved position, thereby ensuring that the milling positions at both ends of the part are consistent, and thus improving the milling accuracy of the parts.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a milling machine for automobile engine parts, including a processing table 1, a support frame 2 fixedly connected to the upper surface of the processing table 1, a slot opened on the upper surface of the support frame 2, a positioning component 3 fixedly connected to the inner wall of the slot, a positioning table 4 fixedly connected to the upper surface of the processing table 1, a hydraulic cylinder 5 fixedly connected to the inner top wall of the positioning table 4, and a milling component 6 fixedly connected to the output end of the hydraulic cylinder 5. Positioning component 3 is used to position automotive tubular parts, and milling component 6 is used to perform milling operations on automotive tubular parts.

[0017] Furthermore, the positioning component 3 includes a support plate 301. A first positioning frame 302 and a second positioning frame 303 are fixedly connected to the upper surface of the support plate 301. Arc-shaped grooves are formed at the same positions on the upper surfaces of the first positioning frame 302 and the second positioning frame 303. A positioning plate 304 is connected to the upper surface of the support plate 301. A cylinder 305 is fixedly connected to the upper surface of the positioning plate 304. A U-shaped frame 306 is fixedly connected to the upper surface of the support plate 301. Limiting grooves are formed on the left and right inner walls of the U-shaped frame 306. A locking rod 307 is fixedly connected to the wall, and a slider 308 is slidably connected to the inner wall of the limiting groove. A movable plate 309 is fixedly connected to the opposite surfaces of the two sliders 308. The sliders 308 and the locking rod 307 are slidably connected, and the movable plate 309 is slidably connected to the inner bottom wall of the U-shaped frame 306. A first positioning rod 310 and a second positioning rod 311 are fixedly connected to the back of the movable plate 309. A limiting block 312 is fixedly connected to the surface of the second positioning rod 311. A milling positioning frame 313 is fixedly connected to the upper surface of the support frame 2. A fixed platform 314 is fixedly connected to the back of the support frame 2. Two support rods 315 are fixedly connected to the front of the fixed platform 314. Milling grooves 316 are opened on the surface of both support rods 315, and the positions of the two support rods 315 correspond to the positions of the first positioning rod 310 and the second positioning rod 311, respectively. The tubular part is first inserted into the surface of the first positioning rod 310. The cylinder 305 drives the movable plate 309 to move backward, which can drive the tubular part to move backward and insert its rear end into the surface of the support rod 315. When the milling assembly 6 processes the tubular part, it is supported by the internal support of the support rod 315. Except for the position of the milling groove 316, other positions of the tubular part will not deform, thereby improving the milling effect of the tubular part. After the rear end of the tubular part is milled, it is flipped and inserted into the surface of the second positioning rod 311. The slotted position of the rear end is locked by the limiting block 312, thereby ensuring that the slotted position of the front end is consistent with the slotted position of the rear end and there will be no deviation, thus improving the accuracy of milling the tubular part.

[0018] Furthermore, the milling assembly 6 includes a right-angle bracket 601. The lower surface of the right-angle bracket 601 has two stabilizing grooves 602, the positions of which correspond to the positions of two arc-shaped grooves. A fixing frame 603 is fixedly connected to the lower surface of the right-angle bracket 601. Two servo motors are fixedly connected to the inner wall of the fixing frame 603. Milling cutters 604 are fixedly connected to the output ends of the two servo motors. The positions of the milling cutters 604 correspond to the positions of the milling grooves 316. After the right-angle bracket 601 is driven down by the hydraulic cylinder 5, the two stabilizing grooves 602 can press the tubular parts to ensure that they do not shift. At the same time, the milling cutters 604 contact the surface of the tubular parts and cooperate with the milling grooves 316 to perform milling and grooving on the tubular parts.

[0019] Working principle: First, the front end of the automotive tubular part to be processed is inserted into the surface of the first positioning rod 310. Since the surface of the first positioning rod 310 has no restrictions, there is no need to worry about the milling position of the tubular part. After the first positioning rod 310 is inserted, the cylinder 305 is activated and drives the movable plate 309 to move backward. The movable plate 309 can squeeze the tubular part through the first positioning rod 310, causing it to move backward in the arc-shaped groove above the first positioning frame 302 and the second positioning frame 303 until the rear end of the tubular part is inserted into the surface of the support rod 315. At this time, the hydraulic cylinder 5 drives the right-angle frame 601 to descend. The right-angle frame 601 can press the tubular part tightly through the stabilizing groove 602 to ensure the stability of the tubular part during processing. At the same time, the milling cutter 604 can engage with the support rod 315. The milling groove 316 on the surface is used to groove the surface of the tubular part. With the overall support of the support rod 315, the tubular part is blocked and supported by the support rod 315 at all positions except the milling groove 316 during the contact with the milling cutter 604, so no deformation occurs. The milling quality of the tubular part is high. After the rear end of the tubular part is milled, the cylinder 305 drives the movable plate 309 to move forward. At the same time, the tubular part is no longer restricted. At this time, the tubular part is taken out, flipped over and inserted into the surface of the second positioning rod 311. The groove position is aligned with the limiting block 312 and inserted, so that the groove positions at both ends of the tubular part are the same. Repeat the above operation to mill and groove both ends of the tubular part.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
