[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0053] Example 1:

[0054] like Figure 1 - Figure 11 As shown, an embodiment of the present invention provides a special CNC machine tool for finishing the shock absorber aluminum cylinder, which includes: a grinding component 2, a linear moving mechanism 4 and a clamping and feeding component 5.

[0055] The grinding assembly 2 is a horizontal structure, which has a horizontally arranged grinding cylinder 203. This embodiment designs a linear moving mechanism 4, which is fixedly connected to the grinding assembly 2, and the moving direction of the linear moving mechanism 4 is along the axial direction of the grinding cylinder 203 of the grinding assembly 2. The clamping and feeding assembly 5 is installed at the action end of the linear moving mechanism 4, and the linear moving mechanism 4 drives the clamping and feeding assembly 5 to approach or move away from the grinding assembly 2. In the process of the linear moving mechanism 4 driving the clamping and feeding assembly 5 to move toward the grinding cylinder 203, the clamping and feeding assembly 5 relies on the inclined block structure to clamp and fix the shock absorber aluminum cylinder.

[0056] When this embodiment is in use, the shock absorber aluminum cylinder is placed on the clamping and feeding assembly 5, and then the linear moving mechanism 4 is driven. During the process of the linear moving mechanism 4 driving the clamping and feeding assembly 5 to move toward the polishing cylinder 203, the clamping and feeding assembly 5 relies on the inclined block structure to clamp and fix the shock absorber aluminum cylinder, and the clamping and feeding assembly 5 carries the shock absorber aluminum cylinder toward the polishing assembly 2, and the polishing cylinder 203 completes the polishing operation on the inside of the shock absorber aluminum cylinder.

[0057] In this embodiment, by designing a linear moving mechanism 4 and a clamping and feeding assembly 5, the linear moving mechanism 4 drives the clamping and feeding assembly 5 to move toward the grinding cylinder 203, and the clamping and feeding assembly 5 relies on the inclined block structure to clamp and fix the shock absorber aluminum cylinder, which simplifies the steps for workers to clamp the shock absorber aluminum cylinder. The user only needs to place the shock absorber aluminum cylinder to drive the linear moving mechanism 4 for grinding feeding, thereby greatly improving the efficiency of the shock absorber aluminum cylinder finishing and meeting market demand.

[0058] In one embodiment, the linear motion mechanism 4 includes: a frame 401, a polished rod 402, a screw rod 403, a second motor 404 and a sliding table 405; the frame 401 is a square structure composed of four vertical plates, which is used to install the polished rod 402 and the screw rod 403. The polished rod 402 is located on the inner side of the frame 401, and the polished rod 402 is fixedly installed with the frame 401. The screw rod 403 is located on the inner side of the frame 401, and the screw rod 403 is rotatably installed with the frame 401. The polished rod 402 and the screw rod 403 should remain parallel. The second motor 404 is fixedly installed with the frame 401. The frame 401 is fixedly installed, and the output end of the second motor 404 is transmission-connected to one end of the screw rod 403. The sliding table 405 is a T-shaped piece composed of a horizontal plate and a vertical plate, and the horizontal plate is fixedly connected to the top of the vertical plate. The vertical plate is located on the inner side of the frame 401, and the vertical plate slides with the optical rod 402, and the vertical plate is threadedly engaged with the screw rod 403, that is, the sliding table 405 is guided by the optical rod 402. The second motor 404 drives the screw rod 403 to rotate, and the screw rod 403 is threadedly engaged with the vertical plate of the sliding table 405, so as to drive the sliding table 405 to move along the length direction of the optical rod 402.

[0059] In one embodiment, in order to prevent metal chips generated during the grinding process from falling into the frame 401 and affecting the coordination between the vertical plate and the polished rod 402 and the screw rod 403, a cover 4a is fixedly provided on the outside of the frame 401 and below the grinding cylinder 203; when necessary, a flexible mask member (not shown in the drawings) can also be provided between the cover 4a and the sliding table 405.

[0060] In one embodiment, the clamping and feeding assembly 5 includes: a sliding seat 506, a first inclined block 5010, a second inclined block 5011, an arc-shaped clamping member 508, a second spring 5012, a driving frame 507, a vertical frame 503, a limiting frame 501 and a support belt 5013, and the sliding seat 506, the first inclined block 5010, the second inclined block 5011, the arc-shaped clamping member 508, the second spring 5012, the driving frame 507, the vertical frame 503, and the limiting frame 501 are symmetrically arranged in two groups.

[0061] The sliding seat 506 is provided with two groups in parallel. A T-shaped opening 506b is provided on the inner side of the sliding seat 506. The first oblique block 5010 is slidably provided on the inner side of the T-shaped opening 506b, and the first oblique block 5010 is also a T-shaped structure. A plurality of fastening screws 509 for fixing the first oblique block 5010 are threadedly installed on the back of the sliding seat 506. One end of the fastening screw 509 is against the back of the first oblique block 5010 to fix the first oblique block 5010 and the sliding seat 506 together. A first inclined surface 5010a is provided on the side of the first oblique block 5010. The second oblique block 5011 is slidably provided in the horizontal opening of the T-shaped opening 506b. Since the second oblique block 5011 has no part located in the vertical opening of the T-shaped opening 506b, the second oblique block 5011 is 011 can slide freely in the horizontal opening of the T-shaped opening 506b (it can slide freely in two directions in the horizontal opening of the T-shaped opening 506b), and the side surface of the second oblique block 5011 is provided with a second oblique surface 5011a corresponding to the first oblique surface 5010a, and the first oblique surface 5010a corresponds to the second oblique surface 5011a to form an oblique block structure. When the second oblique block 5011 slides along the X direction, it is affected by the oblique block structure and can drive the second oblique block 5011 to move synchronously along the Y direction. The outer side of the arc-shaped clamping member 508 is fixedly connected to one end of the second oblique block 5011, and the arc-shaped clamping member 508 slides synchronously with the second oblique block 5011. The inner side of the arc-shaped clamping member 508 is fixedly provided with an anti-slip pad 508a. 08a plays an anti-slip role, which is used to ensure that the shock absorber aluminum cylinder is fixed more reliably. A circular opening 506c is provided on the inner side of the sliding seat 506, and the second spring 5012 is located inside the circular opening 506c. The end of the second spring 5012 is fixedly connected to the inner end of the circular opening 506c, and one end of the second spring 5012 is also fixedly connected to the outer side of the arc-shaped clamping member 508. The second spring 5012 is in a stretched state, which provides an elastic force to make the arc-shaped clamping member 508 have a tendency to move toward the direction close to the sliding seat 506, that is, in some cases, the arc-shaped clamping member 508 can be driven to return. The top of the sliding table 405 is fixedly connected to the raising frame 502, and the bottom end of the driving frame 507 is fixedly connected to the raising frame 502. The raising frame 502 is driven, and the driving frame 507 is driven to move. A sliding hole 5011b is provided on the upper surface of the second inclined block 5011. The sliding hole 5011b is along the Y direction. The top of the driving frame 507 cooperates with the sliding hole 5011b. The driving frame 507 is slidably connected to the second inclined block 5011. The second inclined block 5011 can slide along the Y direction relative to the sliding table 405. The bottom end of the vertical frame 503 is fixedly connected to the top of the sliding table 405. The bottom of the sliding seat 506 is fixedly connected to the vertical plate 506d. Several guide columns 504 are installed between the vertical frame 503 and the vertical plate 506d. Both ends of the guide column 504 have end blocks. The guide column 504 limits the relative movement between the vertical frame 503 and the vertical plate 506d.In the above structure, the stand 503 and the vertical plate 506d can only slide relative to each other along the length direction of the guide column 504. A first spring 505 is provided on the side of the guide column 504 and between the stand 503 and the vertical plate 506d. The first spring 505 is in a compressed state. The first spring 505 is used to drive the stand 503 and the vertical plate 506d to the farthest state, that is, the stand 503 and the vertical plate 506d are respectively against the two end blocks of the guide column 504, and the outer side of the sliding seat 506 is fixedly connected to the cross column 506a, the limiting frame 501 is fixedly connected to the bottom plate of the grinding assembly 2, and the position of the limiting frame 501 corresponds to the position of the horizontal column 506a. When the clamping and feeding assembly 5 as a whole moves away from the grinding assembly 2 to a certain position, the limiting frame 501 blocks the horizontal column 506a. The clamping and feeding assembly 5 continues to move, and the sliding seat 506 does not move with it. In other words, the first spring 505 is further compressed. The support belt 5013 is fixedly connected between the two arc-shaped clamping members 508 and near the bottom of the arc-shaped clamping members 508.

[0062] The specific principle of the clamping and feeding assembly 5 is as follows: the sliding table 405 drives the clamping and feeding assembly 5 to move as a whole in the direction away from the grinding assembly 2. At a certain position, the limiting frame 501 blocks the crossbar 506a, and then the clamping and feeding assembly 5 continues to move. At this time, the sliding seat 506 as a whole no longer moves, which is equivalent to the sliding seat 506 moving in the opposite direction relative to the sliding table 405. At this time, the first spring 505 is further compressed to store energy, and the first inclined block 5010 is fixedly connected to the sliding seat 506. The first inclined block 5010 The second inclined block 5011, the driving frame 507 and the raising frame 502 are fixed to the sliding table 405. The second inclined block 5011, the driving frame 507 and the raising frame 502 will also move with the sliding table 405. There is no longer any squeezing between the second inclined block 5011 and the first inclined block 5010. In this way, under the action of the second spring 5012, the second inclined block 5011 and the arc-shaped clamping member 508 will be pulled to move along the Y-axis direction, so that the two arc-shaped clamping members 508 are in an open state (such as Figure 7 、 Figure 8, the two arc-shaped clamping members 508 are in the open state), the support belt 5013 is pulled into a horizontal state, and the user places the shock absorber aluminum cylinder on the support belt 5013 (the axial direction of the shock absorber aluminum cylinder and the axial direction of the arc-shaped clamping member 508 should be kept basically consistent). After completing the above-mentioned placement of the shock absorber aluminum cylinder, the sliding table 405 drives the clamping and feeding assembly 5 to move as a whole toward the direction close to the grinding assembly 2, and the limiting frame 501 and the horizontal column 506a no longer generate an extrusion force. At this time, under the elastic force of the first spring 505, the sliding seat 506 is relative to the vertical frame 503 (also relative to the vertical frame 503). The sliding table 405 and the second inclined block 5011) move along the X-axis, and the first inclined block 5010 moves with the sliding seat 506. The first inclined block 5010 and the second inclined block 5011 are squeezed. At this time, the second inclined block 5011 is driven to move along the Y-axis direction, so that the two arc-shaped clamping members 508 move toward the middle. The two arc-shaped clamping members 508 clamp and fix the shock absorber aluminum tube. During this process, the second spring 5012 is stretched and accumulates force. In the subsequent driving process of the sliding table 405, the clamping and feeding assembly 5 and the shock absorber aluminum tube move synchronously toward the direction close to the grinding assembly 2.

[0063] In this embodiment, through the specific design of the clamping and feeding component 5, two arc-shaped clamping parts 508 that move synchronously towards each other are used to clamp and fix the shock absorber aluminum cylinder, which can automatically position the center axis of the shock absorber aluminum cylinder. The operator only needs to simply place the shock absorber aluminum cylinder on the support belt 5013, thereby ensuring the installation accuracy of each shock absorber aluminum cylinder and thus ensuring the processing accuracy.

[0064] In one embodiment, the grinding assembly 2 includes: a power box 201, a rotating tooling 202 and a grinding cylinder 203. The power box 201 is installed on a basic work surface. The power box 201 uses a CNC servo motor and can reasonably control the rotation speed. The rotating tooling 202 is fixedly installed at the output end of the power box 201, and the rotating tooling 202 has a horizontal axis, and the grinding cylinder 203 is fixedly installed on the horizontal axis.

[0065] During grinding, the power box 201 drives the rotating tooling 20 to rotate, and then drives the grinding cylinder 203 to rotate. The outer side of the grinding cylinder 203 is the grinding surface, and the inner wall of the shock absorber aluminum cylinder is precisely ground. In some cases, an inflatable variable-diameter grinding cylinder 203 can be used to facilitate the insertion of the grinding cylinder 203 into the shock absorber aluminum cylinder when the grinding cylinder 203 is in a small-diameter state, and then the grinding cylinder 203 is inflated to make the outer side of the grinding cylinder 203 contact the inner wall of the shock absorber aluminum cylinder.

[0066] In one embodiment, a loading tray assembly 1 is further included, which is used to load the above-mentioned clamping and feeding assembly. The loading tray assembly 1 includes: a rotating table 101, an annular tooling 102, a supporting rod 103, an outer ring structure 104 and a lifting assembly 105.

[0067] The rotating table 101 uses a stepper motor, and the rotating table 101 is fixedly connected to the grinding component 2. For example, the grinding component 2 and the rotating table 101 are fixed on the ground to keep the relative positions of the two fixed. The annular tooling 102 is fixedly installed at the top output end of the rotating table 101, and the rotating table 101 drives the annular tooling 102 to rotate. The cross-sectional shape of the annular tooling 102 is L-shaped. A connecting ear 102a is fixedly provided on the outer side of the annular tooling 102. The bottom end of the bearing rod 103 is rotatably mounted with the connecting ear 102a, and the number of the bearing rods 103 is multiple, and the multiple bearing rods 103 are distributed in a circular array. The side of the bearing rod 103 is fixedly connected with a limiting ring 103a, and the limiting ring 1 03a can also be installed with the supporting rod 103 in a threaded manner. The shock absorber aluminum tube is sleeved on the supporting rod 103. The bottom end of the shock absorber aluminum tube is supported by the limiting ring 103a. A support member 104a is provided on the outside of the outer ring structure 104. The support member 104a is fixedly connected to the top surface of the outer shell of the rotating table 101. The outer ring structure 104 is used to limit the outward rotation of the supporting rod 103. The outer ring structure 104 is provided with a notch 104b on the side facing the clamping and feeding component 5. The supporting rod 103 can rotate outward at the notch 104b position. The lifting component 105 is installed on the inside of the notch 104b. The lifting component 105 is used to control the rotation of the supporting rod 103 in the notch 104b.

[0068] When in use, the supporting rod 103 is restricted by the outer ring structure 104 and is in a vertical state (slightly tilted outward). The user puts the shock absorber aluminum tube on the supporting rod 103 in the vertical state, and the rotating table 101 drives the annular tooling 102 and the supporting rod 103 to rotate, and aligns one of the supporting rods 103 with the notch 104b. At this time, since the lifting component 105 is in an elevated position, the supporting rod 103 is still in a vertical state. The user can control the lifting component 105 to rotate downward, and the supporting rod 103 located at the notch 104b position leans on the lifting component 105 and slowly rotates outward. Nearly 90°, the load-bearing rod 103 and the shock absorber aluminum tube are both in a horizontal state. At this time, the shock absorber aluminum tube is located on the inner side of the clamping and feeding assembly 5, and the grinding operation steps are performed. Subsequently, the clamping and feeding assembly 5 still puts the polished shock absorber aluminum tube on the load-bearing rod 103 in a horizontal state. The lifting assembly 105 controls the load-bearing rod 103 to rotate upward, so that the load-bearing rod 103 returns to its original position with the processed shock absorber aluminum tube (so that the load-bearing rod 103 and the processed shock absorber aluminum tube are in a vertical state), and the rotating table 101 drives the annular tooling 102 to rotate a certain angle to continue processing the next shock absorber aluminum tube.

[0069] In one embodiment, the lifting assembly 105 includes: a first motor 10501, a first threaded rod 10502 and a sliding plate 10503.
