Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] In this embodiment, as Figure 1 and Figure 2 As shown, a milling machine fixture for machining rollers includes a workpiece support 1, an adjustable support assembly 2, which can flexibly adjust the support position of the workpiece to suppress bending deformation and cutting vibration of the workpiece; a rotating assembly 3, which is used to rotate the workpiece support 1 to drive the workpiece away from the milling machine for measurement; the adjustable support assembly 2 includes: two I-beam plates 21, both of which are slidably connected to the workpiece support 1 through sliding members 22; a fixed plate 23, which is connected to the end of the two I-beam plates 21 away from the workpiece support 1, and a screw 231 is internally threaded onto the fixed plate 23; an annular washer 24, which is connected to the top end of the screw 231 through a bearing, and the inner ring of the annular washer 24 is used to support the workpiece; a locking member 25 is disposed in the inner ring of the annular washer 24, which is used to lock the position of the workpiece in the annular washer 24.

[0048] Therefore, based on the actual length of the workpiece, the position of the I-plate 21 in the workpiece support 1 is adjusted by the sliding member 22, and the workpiece is placed in the workpiece support 1. The other end of the workpiece extends into the annular washer 24. Then, the screw 231 is rotated in the fixed plate 23. The screw 231 drives the inner ring of the annular washer 24 to abut against the workpiece. Then, the locking member 25 is used to fix the workpiece in the annular washer 24. The workpiece is supported by the workpiece support 1 and the annular washer 24 to prevent the workpiece from sagging due to its own weight. The locking member 25 clamps the workpiece at multiple points, which increases the stability of the workpiece during processing and reduces the impact of vibration on the processing accuracy.

[0049] Specifically, the I-shaped plate 21 is designed with two slots, and two through slots adapted to the I-shaped plate 21 are opened in the workpiece bearing seat 1. The sliding member 22 is used to constrain the lateral movement of the I-shaped plate 21. The rotating screw 231 can adjust the height of the annular washer 24 to support the workpiece. The locking member 25 cooperates with the annular washer 24 to fix the workpiece.

[0050] In some embodiments, such as Figure 2 and Figure 3 As shown, the locking component 25 includes: a slide rod 251, which is inserted into and connected to an annular washer 24, and the slide rod 251 is connected to the annular washer 24 through a fixing component 252; a mounting bracket 253, which is connected to the bottom end of the slide rod 251; and two pressure rollers 254, both of which are connected to the mounting bracket 253 through pins.

[0051] Specifically, the slide rod 251 and the screw 231 are located on the same axis. The slide rod 251 can drive the mounting frame 253 to move vertically. After the two pressure rollers 254 abut against the outer wall of the workpiece, they cooperate with the annular washer 24 to fix the workpiece in three positions to increase the stability of the workpiece when it is fixed.

[0052] In some embodiments, such as Figure 2 As shown, the fastener 252 includes: a collar 252a, which is located at the top of the annular washer 24. The collar 252a is inserted and connected to the slide rod 251. The collar 252a is connected to the slide rod 251 by a bolt 252b.

[0053] Specifically, the collar 252a is fitted around the outer circumference of the slide rod 251, and the bolt 252b in the collar 252a is connected to the slide rod 251 to fix the position of the slide rod 251 in the annular washer 24.

[0054] In some embodiments, such as Figure 4 As shown, the sliding member 22 includes: a right-angle bracket 221, one end of which is connected to the workpiece bearing seat 1, and the other end of which is hinged to a guide wheel 222, which is adapted to the groove of the I-shaped plate 21; and a positioning pin 223, through which the right-angle bracket 221 is connected to the I-shaped plate 21.

[0055] Specifically, each I-beam plate 21 has four right-angle brackets 221 symmetrically distributed on its upper and lower sides. The guide wheels 222 are rotatably connected to the right-angle brackets 221 through pins. The symmetrically distributed guide wheels 222 constrain the travel direction of the I-beam plate 21. After the positioning pins 223 are connected to the I-beam plate 21, they fix the position of the I-beam plate 21 in the workpiece bearing seat 1.

[0056] In some embodiments, such as Figure 5 As shown, the rotating assembly 3 includes: a rotating shaft 31, the top end of the rotating shaft 31 is fixedly connected to the workpiece bearing seat 1, and threaded holes 31a are evenly distributed on the outer peripheral surface of the rotating shaft 31; a milling machine connecting plate 32, which is connected to the rotating shaft 31 through a bearing, and the milling machine connecting plate 32 is equipped with a limiting member 33, which is used to limit the rotation of the rotating shaft 31.

[0057] Specifically, the top end of the rotating shaft 31 is fixedly connected to the workpiece bearing seat 1, and the bottom end of the rotating shaft 31 is rotatably connected to the milling machine connecting plate 32. Thus, when the rotating shaft 31 rotates in the milling machine connecting plate 32, it drives the workpiece bearing seat 1 to rotate. The threaded holes 31a are distributed in a ring around the outer periphery of the rotating shaft 31.

[0058] In some embodiments, such as Figure 5As shown, the limiting member 33 includes: an arc-shaped plate 331, the bottom end of which is connected to the milling machine connecting plate 32, and the arc-shaped plate 331 is connected to the threaded hole 31a through the limiting pin 332;

[0059] Specifically, the outer wall of the limiting pin 332 is machined with threads that are compatible with the threaded hole 31a. The limiting pin 332 is inserted into the threaded hole 31a to restrict the rotation of the rotating shaft 31.

[0060] In some embodiments, such as Figure 5 As shown, connecting plates 321 are symmetrically distributed on the outer periphery of the milling machine connecting plate 32. The connecting plates 321 are used to connect with the milling machine's worktable.

[0061] Specifically, there are two connecting plates 321. The connecting plates 321 are connected to the milling machine's worktable to mount the entire mechanism onto the milling machine's worktable.

[0062] In some embodiments, such as Figure 6 As shown, the top of the workpiece support 1 is provided with an abutment component 4; the abutment component 4 includes: a guard plate 41, which is connected to the workpiece support 1 by a threaded pin 411; and an adjusting cylinder 42, which is fixedly connected to the guard plate 41. A push rod 421 is internally threaded in the adjusting cylinder 42 and is used to press against the workpiece.

[0063] Specifically, the guard plate 41 is machined into an arc shape, and each guard plate 41 is equipped with a threaded pin 411 at both ends. A connecting hole adapted to the threaded pin 411 is opened at the top of the workpiece bearing seat 1. The outer wall of the push rod 421 is machined with threads, and the threads on the outer wall of the push rod 421 are adapted to the internal threads of the adjusting cylinder 42. The workpiece is pressed against by adjusting the position of the push rod 421 in the adjusting cylinder 42.

[0064] In some embodiments, such as Figure 6 As shown, a rubber block 421a is fixedly connected to the bottom end of the top rod 421.

[0065] Specifically, each push rod 421 is designed with a rubber block 421a at its bottom end. The plasticity of the rubber block 421a is used to buffer the squeezing force of the push rod 421 on the outer wall of the workpiece and prevent indentations from appearing on the outer wall of the workpiece.

[0066] In some embodiments, such as Figure 5 As shown, a V-groove 11 is machined on the top of the workpiece support 1.

[0067] The V-groove 11 design facilitates the bearing of roller-shaped workpieces of different diameters.

[0068] The working principle of this application is illustrated below with a preferred embodiment:

[0069] The milling machine connects to the milling machine table via the connecting plate 321 on the milling machine connecting plate 32. Then, the roller-shaped workpiece is placed in the V-groove 11 of the workpiece carrier 1. The guard plate 41 is fastened to the top of the workpiece. The guard plate 41 and the workpiece carrier 1 are connected by the threaded pin 411. Then, the push rod 421 is rotated in the adjusting cylinder 42. The push rod 421 drives the rubber block 421a to press against the workpiece. Two rows of connecting holes that are compatible with the threaded pin 411 are machined on the top of the workpiece carrier 1. Thus, the number of guard plates 41 used can be selectively installed according to the requirements.

[0070] Next, the I-shaped plate 21 is moved in the workpiece support 1. The I-shaped plate 21 moves along the guide wheel 222 in the right angle frame 221. The screw 231 is rotated in the fixed plate 23. The screw 231 adjusts the height of the annular washer 24. Then, the I-shaped plate 21 is moved in the opposite direction to drive the annular washer 24 to be inserted into the end of the workpiece away from the workpiece support 1. Then, the height of the annular washer 24 is adjusted until the inner wall of the annular washer 24 abuts against the outer circumference of the workpiece. The positioning pin 223 in the right angle frame 221 is rotated to connect with the I-shaped plate 21, thereby fixing the I-shaped plate 21 laterally. Then, the slide rod 251 is moved in the annular washer 24. The slide rod 251 drives the two pressure rollers 254 to abut against the workpiece through the mounting frame 253. The bolt 252b in the rotating collar 252a is connected to the slide rod 251, thereby clamping the workpiece with the two pressure rollers 252 and the annular washer 24.

[0071] When it is necessary to measure the workpiece, the limiting pin 332 in the rotating arc plate 331 is separated from the threaded hole 31a. Then, the rotating shaft 31 is rotated in the milling machine connecting plate 32. The rotating shaft 31 causes the workpiece bearing seat 1 to deflect, and then the workpiece is moved out of the milling machine. After the measurement is completed, the rotating shaft 31 is rotated to drive the workpiece back to the processing position. Without disassembling the workpiece, the workpiece can be offset out of the milling machine for measurement.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
