Description

Technical Field

[0001] This utility model relates to the field of automotive driveshaft grinding application technology, specifically, to a driveshaft grinding device. Background Technology

[0002] In precision mechanical transmission, high transmission accuracy is often required. As the number of transmission stages increases, the requirements for the manufacturing accuracy and service life of transmission components also increase. The drive shaft is an important component of the automotive transmission mechanism, and its production and processing quality directly affects the performance of the transmission mechanism.

[0003] A search revealed that Chinese patent CN218696738U discloses a grinding machine for automotive driveshaft production. In operation, the machine first adjusts the movable fixed frame to insert the driveshaft into the rotating frame, securing it with locking bolts. Next, adjusting bolts move the grinding plate on the movable plate, bringing it into contact with the driveshaft body. Then, a rotating motor is started, driving the shaft to rotate the worm gear, which in turn rotates the worm wheel. This causes the rotating frame to rotate rapidly. Simultaneously, a vacuum cleaner collects dust into the dust collection box. Another moving motor is started, driving the shaft to rotate the lead screw, which in turn moves the threaded moving block, adjusting the movable plate and enabling rapid grinding of the driveshaft.

[0004] The applicant discovered the following technical problems when implementing the above-mentioned technical solution:

[0028] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0029] Reference Figure 1 and Figure 2 A drive shaft grinding device includes: a worktable 1, a fixed frame 2, a diameter adjustment mechanism 3, grinding rollers 4, and a rotary drive mechanism 5. The fixed frame 2 is vertically spaced on the worktable 1, and a circular hole 201 is provided through its frame. The diameter adjustment mechanism 3 is arranged around the circular hole 201 on one side of each adjacent fixed frame 2. A plurality of grinding rollers 4 are arranged around the circular hole 201 at intervals. The grinding rollers 4 are rotatably mounted on the diameter adjustment mechanism 3 at opposite ends. The diameter adjustment mechanism 3 can be adjusted according to the diameter of the drive shaft to facilitate grinding of the drive shaft by the grinding rollers 4. The rotary drive mechanism 5 is arranged on the worktable 1 and can drive the drive shaft to rotate.

[0030] This application achieves the grinding function by placing the drive shaft in the circular hole 201, then activating the diameter adjustment mechanism 3 to adjust according to the diameter of the drive shaft, so as to drive the grinding roller 4 to fit against the circumference of the drive shaft, and then activating the rotation drive mechanism 5 to drive the drive shaft to rotate; thus realizing the function of drive shafts with multiple diameters.

[0031] Reference Figure 2 and Figure 4 The diameter adjustment mechanism 3 includes a rotating disk 301, a limiting rod 302, and a first driving assembly 303. The rotating disk 301 is coaxially and rotatably disposed on one side of the circular hole 201, and several limiting rods 302 are arranged around its periphery. Several limiting sleeves 30101 adapted to the limiting rods 302 are rotatably disposed on the rotating disk 301 around the circular hole 201. One end of the limiting rod 302 is rotatably disposed on the fixed frame 2 at the periphery of the rotating disk 301, and the other end extends through the limiting sleeve 30101. The grinding roller 4 is rotatably disposed at opposite ends at the ends of the limiting rods 302 extending out of the limiting sleeves 30101. The first driving assembly 303 is used to drive the rotating disk 301 to rotate.

[0032] This application achieves inner diameter adjustment by activating the first drive assembly 303 to drive the rotating disk 301 to rotate, thereby driving the corresponding grinding roller 4 to move toward the axis of the circular hole 201 via each limit rod 302.

[0033] Reference Figure 4 and Figure 5The first drive assembly 303 includes a first limiting block 30301, a second limiting block 30302, and an adjusting screw 30303.

The adjusting screw 30303 is threaded through the first limiting block 30301 and the second limiting block 30302.

[0034] This application achieves the rotation of the rotating disk 301 by rotating the adjusting screw 30303 to make the first limiting block 30301 gradually approach or move away from the second limiting block 30302.

[0035] Reference Figure 5 The adjusting screw 30303 is equipped with a first drive motor 30304 at one end for driving its rotation.

[0036] This application achieves the rotation of the rotating disk 301 by starting the first drive motor 30304 to drive the adjusting screw 30303 to rotate.

[0037] Reference Figure 5 An anti-detachment block 30305 is provided at the end of the adjusting screw 30303 away from the first drive motor 30304.

[0038] This application uses an anti-detachment block 30305 to prevent the adjusting screw 30303 from separating from the first limit block 30301.

[0039] Reference Figure 2 and Figure 3 The rotary drive mechanism 5 includes a second drive motor 501, a movable frame 502, and a second drive assembly 503.

A limit slide rail 101 is provided on the worktable 1 away from the second drive motor 501. The movable frame 502 is movably disposed in the limit slide rail 101, and a top column 50201 that can abut against one end of the transmission shaft is rotatably disposed on the side of the movable frame 502 near the second drive motor 501. The second drive assembly 503 is disposed on the worktable 1 and can drive the movable frame 502 to reciprocate toward the fixed frame 2.

[0040] This application activates the second drive assembly 503 to move the movable frame 502 toward the fixed frame 2, and uses the top column 50201 and drive column 50101 to press the drive shaft together, and then activates the second drive motor 501 to drive the drive shaft to rotate.

[0041] Reference Figure 3The limiting slide rail 101 is provided with a limiting slide groove 10101, and the moving frame 502 is provided with a limiting slider 50202 that is adapted to the limiting slide groove 10101.

[0042] The movable frame 502 of this application is movably disposed within the limiting slide groove 10101 by the limiting slider 50202 to ensure that it will not separate.

[0043] Reference Figure 3 The second drive assembly 503 includes a third drive motor 50301 and a lead screw 50302. The third drive motor 50301 is located at one end of the worktable 1 away from the second drive motor 501, and the lead screw 50302 is rotatably coaxially arranged at its output end. The lead screw 50302 is threaded through the movable frame 502.

[0044] This application achieves the reciprocating movement of the moving frame 502 by starting the third drive motor 50301 to drive the lead screw 50302 to rotate.

[0045] When using the device provided by this utility model, the drive shaft is placed in the circular hole 201, and then the diameter adjustment mechanism 3 is activated to adjust according to the diameter of the drive shaft, so as to drive the grinding roller 4 to fit against the circumference of the drive shaft.
