[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention reduces the vibration of shaft workpieces during the material transfer process through a shock-absorbing component, that is, when the shaft workpiece is moved from the previous material slot to the next material slot by the step-by-step material transfer component, the shaft workpiece remains stable under the action of the lower pressure piece and the side pressure piece, thereby achieving a shock-absorbing effect on the shaft workpiece during the material transfer process.

[0018] 2.

Combined with the guide roller, the elastic band is tightly clamped on the shaft workpiece, so that the surface of the elastic band fits with the shaft workpiece over a large area, ensuring that the shaft workpiece is more stable. As the shaft workpiece moves in the discharge direction, the movable plate is prompted to move with it until the shaft workpiece is moved to the next clamping groove. The shaft workpiece is then separated from the two guide rollers. Under the action of the reset connector, all the movable plates are quickly reset to prepare for the subsequent movement of the shaft workpiece, thereby greatly reducing the vibration of the shaft workpiece during movement and improving processing accuracy and production efficiency.

[0019] 3. The present invention clamps the shaft workpiece by two limit plates, so that the shaft workpiece is laterally damped, and the rubber pocket on the limit plate provides additional buffering effect for the support of the shaft workpiece. Combined with the elastic belt, the shaft workpiece obtains a double damping effect in the elastic belt and the rubber pocket, which reduces the vibration of the shaft workpiece during movement, improves processing accuracy, and also ensures product quality.

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] See also Figure 1-Figure 7 As shown, a vibration-damping material moving device for machining shaft workpieces includes a frame 1 and a material discharging assembly 2 arranged on the frame 1, and a step-type material moving assembly 3, wherein the material discharging assembly 2 has a pair of mutually parallel clamping plates 21, and the clamping plates 21 are provided with clamping grooves 211 for limiting the movement of the shaft workpiece 5 at equal intervals along the length direction thereof, and a vibration-damping assembly 4 cooperating with the step-type material moving assembly 3 is provided on the frame 1, and the vibration-damping assembly 4 includes a downward pressure for slowing down the vertical vibration of the shaft workpiece 5 Part 41, and a side pressure part 42 for reducing the lateral vibration of the shaft workpiece 5, the lower pressure part 41 is arranged above the step-by-step material shifting component 3, and the side pressure part 42 has a pair, and a pair of side pressure parts 42 are symmetrically arranged on both sides of the discharge component 2. When the shaft workpiece 5 is moved from the previous material slot 211 to the next material slot 211 by the step-by-step material shifting component 3, the shaft workpiece 5 moves upward and contacts with the lower pressure part 41, so that the shaft workpiece 5 remains stable under the action of the lower pressure part 41.

[0033] When the shaft workpiece 5 is being processed, the shaft workpiece 5 is placed in the clamping groove 211 of a pair of clamping plates 21. The clamping grooves 211 are arranged at equal intervals along the length direction of the clamping plates 21 to limit the movement of the shaft workpiece 5. The shaft workpiece 5 is supported by the pair of clamping plates 21 so that the shaft workpiece 5 remains in a horizontal state. With the start of the step-type material shifting assembly 3, the shaft workpiece 5 is lifted upward from the clamping groove 211 at the current position. During the lifting process, the shaft workpiece 5 will contact the lower pressing piece 41 in the shock absorbing assembly 4. Since the lower pressing piece 41 is arranged above the step-type material shifting assembly 3, when the shaft workpiece 5 is lifted, it will contact the lower pressing piece 41. At this time, the lower pressing piece 41 passively presses the shaft workpiece 5 to reduce the vibration generated by the shaft workpiece 5 during the lifting process. Since a pair of side pressure members 42 are symmetrically arranged on both sides of the discharge component 2, the shaft workpiece 5 is restricted between the pair of side pressure members 42 after being placed on the clamping plate 21. The two ends of the shaft workpiece 5 are respectively in contact with a side pressure member 42 to reduce the vibration of the shaft workpiece 5 in the horizontal direction. Under the action of the lower pressure member 41 and the side pressure member 42, the shaft workpiece 5 remains stable, and the step-by-step material moving component 3 continues to drive the shaft workpiece 5 to move, continuously moving the shaft workpiece 5 from the previous clamping slot 211 to the next clamping slot 211, and finally realizing the intermittent movement of batches of shaft workpieces 5.

[0034] See also Figure 4-Figure 7 , Fig. 9 and Fig.10 As shown, the pressing member 41 has an elastic band 411 arranged along the direction in which the shaft workpiece 5 is conveyed, and the two ends of the elastic band 411 are respectively fixedly connected to the frame 1. When the shaft workpiece 5 is in the clamping groove 211, the surface of the elastic band 411 is tangent to the surface of the shaft workpiece 5.

[0035] When the shaft workpiece 5 is lifted, the elastic band 411 is deformed under the pressure of the shaft workpiece 5. At this time, the elastic band 411 presses against the shaft workpiece 5, reducing the vibration of the shaft workpiece 5 in the vertical direction and maintaining stability until the shaft workpiece 5 is moved from the previous clamping groove 211 to the next clamping groove 211. The elastic band 411 recovers to a state without external force, so that the shaft workpiece 5 can still maintain a stable state under the action of the elastic band 411 when it is moved next time.

[0036] See also Figure 4-Figure 7 , Fig. 9 and Fig.10 As shown, the lower pressing member 41 also has a movable plate 412 arranged corresponding to each clamping groove 211, and the movable plate 412 can move on the frame 1 along the direction in which the shaft workpiece 5 is conveyed. A guide roller 4121 is respectively provided on both sides of the movable plate 412, and the guide roller 4121 is located above the elastic band 411. A gap is formed between the two guide rollers 4121 for the shaft workpiece 5 to be clamped therein.

[0037] When the shaft workpiece 5 is lifted from the clamping groove 211, the shaft workpiece 5 applies upward pressure to cause the elastic band 411 to deform. Since the two guide rollers 4121 are located on both sides of the shaft workpiece 5, the part of the elastic band 411 located between the two guide rollers 4121 is deformed. As the shaft workpiece 5 is lifted to the gap formed between the two guide rollers 4121, the deformed part of the elastic band 411 is tightly attached to the surface of the shaft workpiece 5, which has a clamping effect and helps to stabilize the lifting process of the shaft workpiece 5 until the shaft workpiece 5 contacts the movable plate 412. At this time, the shaft workpiece 5 is completely lifted to a position away from the current clamping groove 211. As the step-by-step material shifting assembly 3 continues to start, the shaft workpiece 5 is moved to the next clamping groove 211.

[0038] See also Figure 4-Figure 7 , Fig. 9 and Fig.10 As shown, a guide rail 11 for all movable plates 412 to slide is fixedly provided on the frame 1, and the movable plates 412 are provided with a pulley 111 slidably connected to the guide rail 11, and a reset connector 12 is fixedly connected between all movable plates 412.

[0039] When the shaft workpiece 5 is lifted between the two guide rollers 4121, the shaft workpiece 5 is pushed toward the discharging direction by the step-by-step material shifting assembly 3. At this time, since the shaft workpiece 5 is stuck in the two guide rollers 4121, the movable plate 412 is pushed along with the shaft workpiece 5. At this time, the movable plate 412 slides along the guide rail 11 through the pulley 111 until the shaft workpiece 5 moves to the top of the next clamping groove 211. The step-by-step material shifting assembly 3 lowers the shaft workpiece 5 into the clamping groove 211. At this time, the shaft workpiece 5 is separated from the two guide rollers 4121. Due to the action of the reset connector 12, all the movable plates 412 return to their original positions, which is beneficial to the shock-absorbing effect on the subsequent shaft workpieces 5.

[0040] See also Figure 4-Figure 7 , Fig. 9 and Fig.10 As shown, the reset connector 12 has a strip 121 fixedly connected to all movable plates 412, and a reset spring 122 fixedly connected between the strip 121 and the guide rail 11, and the guide rail 11 is fixedly provided with a bar 112 along its length direction for the strip 121 to be slidably connected thereto, and both ends of the strip 121 have sliders 1211 slidably mounted on the bar 112.

[0041] When the shaft workpiece 5 is pushed toward the discharging direction by the step-by-step material moving assembly 3, since the shaft workpiece 5 is stuck in the two guide rollers 4121, the movable plate 412 is pushed along with the shaft workpiece 5, and the movable plate 412 slides along the guide rail 11 through the pulley 111, driving the strip plate 121 fixed thereto to move together, and the slider 1211 of the strip plate 121 slides on the bar 112, and the strip plate 121 moves synchronously with the movable plate 412. At this time, the reset spring 122 is stretched, and the shaft workpiece 5 moves to the next Directly above the material slot 211, the step-by-step material moving assembly 3 lowers the shaft workpiece 5 into the material slot 211, and the shaft workpiece 5 disengages from the two guide rollers 4121. After the shaft workpiece 5 disengages from the guide rollers 4121, the movable plate 412 is no longer subject to the driving force, and the strip plate 121 is no longer subject to the thrust of the movable plate 412. The return spring 122 drives the strip plate 121 to move back, and the strip plate 121 drives the movable plate 412 fixed thereto to move back, returning to the initial position, and preparing for the subsequent movement of the shaft workpiece 5.

[0042] See also Fig. 9 and Fig.10 As shown, a movable magnet 1212 is fixedly connected to the slider 1211 at one end of the strip 121 close to the feeding direction, and a fixed magnet 1213 is fixedly connected to the guide rail 11. When the movable magnet 1212 and the fixed magnet 1213 are in contact, the reset spring 122 is in a state of not being acted upon by external force.

[0043] When the movable magnet 1212 approaches the fixed magnet 1213, a magnetic attraction is generated between the two, the movable magnet 1212 fits with the fixed magnet 1213, the reset spring 122 returns to a natural state, the strip 121 and the movable plate 412 return to their initial positions, so that the next time the shaft workpiece 5 is conveyed, it can accurately enter the two guide rollers 4121, thereby ensuring stable transportation of the shaft workpiece 5 between the two guide rollers 4121.

[0044] See also Figure 6 and Figure 7 As shown, the clamping plate 21 has a horizontal surface at one end in the feeding direction and another end in the discharging direction for the shaft workpiece 5 to be placed in and taken out.

[0045] One end of the clamping plate 21 in the feeding direction and one end in the discharging direction are designed to be horizontal planes, which is convenient for placing and removing the shaft workpiece 5, helps to improve the convenience of operation, and reduces the time required for placing and removing the shaft workpiece 5.

[0046] See also Figure 1-Figure 3As shown, the step-by-step material moving assembly 3 includes a step-by-step material rack 31 respectively arranged on the outside of each clamping plate 21, and a step-by-step driver 32 for driving the step-by-step material rack 31 to reciprocate along the step-by-step trajectory direction. A groove for supporting the shaft workpiece 5 is provided on the step-by-step material rack 31 corresponding to each clamping groove 211.

[0047] The specific structure of the stepper driver 32 is not shown in the figure. The shaft workpiece 5 is placed into the horizontal plane at one end of the feeding direction of the clamping plate 21. As the stepper driver 32 is started, the stepper feed frame 31 is driven to move along the stepping track. The groove on the stepper feed frame 31 corresponds to the shaft workpiece 5, and the shaft workpiece 5 is lifted. The stepper feed frame 31 continues to move along the stepping track, driving the shaft workpiece 5 to move to the next clamping slot 211, thereby realizing the stepping movement of the shaft workpiece 5.

[0048] See also Figure 1-Figure 5 and Figure 8 As shown, each step feed frame 31 is provided with a side pressure piece 42, and the side pressure piece 42 has a limit plate 421 that contacts the end of the shaft workpiece 5, and a compression spring 422 fixedly connected between the step feed frame 31 and the limit plate 421, and the compression spring 422 is used to ensure that the limit plate 421 contacts the shaft workpiece 5.

[0049] By setting a limit plate 421 on each stepping material rack 31, the shaft workpiece 5 can be stuck between the two limit plates 421 to limit its lateral movement, thereby reducing the lateral vibration of the shaft workpiece 5. Since the limit plate 421 is connected to the stepping material rack 31 through the compression spring 422, the distance between the two limit plates 421 can automatically adapt to the length of the shaft workpiece 5, and the limit plate 421 is always kept in contact with the end of the shaft workpiece 5, thereby improving the stability of the shaft workpiece 5 being transported.

[0050] See also Figure 6-Figure 8 As shown, a rubber material pocket 4211 is provided in each groove on the limiting plate 421 corresponding to the stepping material rack 31, and the rubber material pocket 4211 can move along the axial direction where the shaft workpiece 5 is placed.

[0051] The rubber material pocket 4211 can provide a buffering effect for the support of the shaft workpiece 5. Combined with the elastic band 411, the shaft workpiece 5 can obtain a shock-absorbing effect in the elastic band 411 and the rubber material pocket 4211. Since the rubber material pocket 4211 on the limit plate 421 is slidably set in the corresponding groove on the step feed frame 31, the movement of the limit plate 421 has a guiding effect, keeping the limit plate 421 in a vertical state in contact with the shaft workpiece 5, thereby improving the stability of the shaft workpiece 5 during movement.

[0052] The present invention uses a shock-absorbing component 4 to reduce the vibration of the shaft workpiece 5 during the material transfer process. That is, when the shaft workpiece 5 is moved from the previous material slot 211 to the next material slot 211 by the step-by-step material transfer component 3, the shaft workpiece 5 remains stable under the action of the lower pressure piece 41 and the side pressure piece 42, thereby achieving a shock-absorbing effect on the shaft workpiece 5 during the material transfer process. Compared with traditional step-by-step material transfer, it can effectively reduce the vibration of the shaft workpiece 5 during the material transfer process, improve processing accuracy and production efficiency, and ensure the quality of the shaft workpiece 5.

[0053] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
