Description

Technical Field

[0001] This utility model relates to the field of mechanical turning technology, specifically to a forming device for the end of a rearview mirror support rod. Background Technology

[0002] The rearview mirror support rod is used to mount the rearview mirror to motorcycles and electric vehicles via a threaded connection, thus requiring the machining of threaded sections on the support rod. While the forming equipment initially introduced by the applicant automated the threaded section machining through the coordination of the worktable, the support rod clamping mechanism (which rotates the support rod), and the turning mechanism (exposing the cutting tool), it was found in actual production that the metal chips cut by the cutting tool accumulated on the worktable, affecting production efficiency.

[0003] The main problem is that the iron filings generated during the turning of the support rod accumulate on the worktable, causing critical components such as the feed guide to become jammed. This can lead to two main issues: firstly, deviations in the concentricity of the support rod's rotation, resulting in quality problems such as tapered and asymmetrical thread profiles during thread machining; and secondly, it can trigger sudden machine stoppages. Production records show that equipment downtime due to iron filings occurs 1-2 times every 2-3 days, with each incident taking 15-20 minutes, directly resulting in a production capacity loss of approximately 2%.

[0004] Therefore, there is an urgent need to design a thread rolling device to improve product production efficiency. Utility Model Content

[0005] The present invention aims to provide a forming device for the end of a rearview mirror support rod to improve the production efficiency of the rearview mirror support rod.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a forming device for the end of a rearview mirror support rod, comprising a worktable, a turning mechanism, and a support rod clamping mechanism for driving the rearview mirror support rod to rotate. The worktable is provided with a sliding mechanism for guiding the turning mechanism, the sliding mechanism including a transverse sliding mechanism and a longitudinal sliding mechanism. The turning mechanism includes a turning table and a cutting tool mounted on the turning table. The turning table has a chip guide groove along the axial direction of the cutting tool. The chip guide groove is inclined downward along one side of the support rod clamping mechanism to form an inclined guide surface. The side of the chip guide groove that is in the same direction as the cutting edge of the cutting tool extends outward to form a chip receiving plate. An inclined chip discharge groove is provided on the worktable below the inclined guide surface.

[0007] Preferably, as an improvement, the chip guide groove is provided with a chip removal auxiliary wheel, the lower surface of which protrudes from the inner surface of the chip guide groove.

[0008] Preferably, as an improvement, the surface of the chip removal auxiliary wheel is provided with a friction unit, which includes one or a combination of raised dots and raised strips with a concave-convex design.

[0009] Preferably, as an improvement, a pressure sensing plate is provided on the surface of the chip removal auxiliary wheel.

[0010] Preferably, as an improvement, the extension length of the scrap receiving plate is 3-4 cm.

[0011] Preferably, as an improvement, the transverse sliding mechanism includes a transverse slide rail fixed to the worktable and a transverse slide table slidably connected to the transverse slide rail.

[0012] Preferably, as an improvement, the longitudinal sliding mechanism includes a support rod fixed to the transverse slide table, and a longitudinal slide rail is provided on the support rod, and the turning table is slidably connected to the longitudinal slide rail.

[0013] Preferably, as an improvement, the workbench is provided with a transfer plate for conveying the rearview mirror support rod, and the cross-section of the transfer plate is V-shaped.

[0014] The principle and advantages of this scheme are:

[0015] 1. This solution incorporates a chip guide groove within the turning table and cleverly designs its structure. This allows the metal chips cut from the end of the rearview mirror support rod to be concentrated and discharged from the inclined guide surface into the chip removal groove. On the one hand, this avoids the metal chips interfering with the movement of the mechanical components, thus preventing poor product quality and low production efficiency. On the other hand, it keeps the worktable clean and tidy, and on the other hand, it eliminates the need for workers to clean the metal chips, saving labor costs.

[0016] 2. Under normal circumstances, the cut chips fall smoothly into the chip receiving plate along the left side of the cutting tool and are discharged smoothly. However, under special circumstances, the trajectory of some chips may change and move along the chip guide groove above the cutting tool. Since the cutting tool does not rotate during the cutting process, chips can easily accumulate between the cutting tool and the chip guide groove. Excessive accumulation affects the heat dissipation of the cutting tool. More importantly, because the temperature of freshly cut chips is extremely high, reaching about 600℃, if they continue to accumulate at the cutting tool and the heat cannot be dissipated in time, it will affect the performance of the cutting tool. Therefore, this solution, by setting up a chip removal auxiliary wheel and its related structure, can effectively remove the chips accumulated between the chip guide groove and the cutting tool in a timely manner, so as to avoid affecting the performance of the turning mechanism.

Detailed Implementation

[0020] The following detailed description illustrates the specific implementation method:

[0021] The basic implementation examples are as follows: Figure 1 The diagram shows a forming device for the end of a rearview mirror support rod, comprising a worktable 1, a turning mechanism, and a support rod clamping mechanism 2 for rotating the rearview mirror support rod 6. The worktable 1 is equipped with a sliding mechanism for guiding the turning mechanism. The sliding mechanism includes a transverse sliding mechanism and a longitudinal sliding mechanism. The transverse sliding mechanism includes a transverse slide rail 3 fixed to the worktable 1 and a transverse slide table 4 slidably connected to the transverse slide rail 3. The longitudinal sliding mechanism includes a support rod body 5 fixed to the transverse slide table 4, with a longitudinal slide rail on the support rod body 5. A turning table 8 is slidably connected to the longitudinal slide rail. Reciprocating drive mechanisms 7 are fixedly installed on both the transverse slide rail 3 and the support rod body 5. The output ends of the two reciprocating drive mechanisms 7 are respectively fixed to the transverse slide table 4 and the turning table 8.

[0022] like Figure 2 As shown, the turning mechanism includes a turning table 8 and a cutting tool 9 mounted on the turning table 8. A chip guide groove 10 is provided at one end of the turning table 8 near the support rod clamping mechanism 2. The chip guide groove 10 has a C-shaped cross-section and is open on either side of the transverse slide 4. The cutting tool 9 is fixedly mounted inside the chip guide groove 10, with its cutting edge extending beyond the opening. The bottom surface of the chip guide groove 10 is inclined downwards along one side of the support rod clamping mechanism 2 to form an inclined guide surface 11. The lower surface of the chip guide groove 10 extends outwards along the opening direction to form a chip receiving plate 12, used to receive the chips cut by the cutting tool 9 and discharge them promptly through the inclined guide surface 11, preventing accumulation on the worktable 1. Since the length of the chips cut from the support rod is typically around 4 cm, in this embodiment, the extension length of the chip receiving plate 12 is designed to be 3-4 cm. An inclined chip removal groove 13 is provided on the worktable 1, located below the inclined guide surface 11.

[0023] During the cutting process, under normal circumstances, the cut iron chips fall smoothly into the iron chip receiving plate 12 along the left side of the cutting tool 9 and are discharged smoothly. However, under special circumstances, some iron chips may move along the chip guide groove 10 above the cutting tool 9. Since the cutting tool 9 does not rotate during the cutting process, iron chips may accumulate between the cutting tool 9 and the chip guide groove 10. If too many chips accumulate, it will affect the heat dissipation of the cutting tool 9. More importantly, since the temperature of the freshly cut iron chips is extremely high, reaching about 600°C, if they continue to accumulate at the cutting tool and the heat cannot be dissipated in time, it will affect the performance of the cutting tool.

[0024] Therefore, to solve the above problems, a chip removal auxiliary wheel 14 is provided on the upper right side of the chip guide groove 10. The chip removal auxiliary wheel 14 is driven to rotate by a micro motor. The lower surface of the chip removal auxiliary wheel 14 protrudes slightly downward from the surface of the chip guide groove 10 by 0.5cm-1cm. The surface of the chip removal auxiliary wheel 14 is provided with friction units, including raised dots and raised strips with concave and convex designs. At the same time, a pressure sensing plate is provided on the wheel surface of the chip removal auxiliary wheel 14. When the pressure sensing plate senses the pressure of the iron chips, the micro motor is controlled by the PLC controller (existing technology) to drive the chip removal auxiliary wheel 14 to rotate, thereby discharging the iron chips accumulated between the chip guide groove 10 and the cutting tool 9.

[0025] The workbench 1 is equipped with a transfer plate 15 for conveying the rearview mirror support rod 6. The cross-section of the transfer plate 15 is V-shaped. The central axis of the transfer plate 15 is located in the same plane as the central axis of the support rod clamping mechanism, so that the rearview mirror support rod 6, which has been machined at the end, can be smoothly pushed into the transfer plate 15 for conveying.
