Description

Technical Field

[0001] This application relates to the technical field of machining lathes, and in particular to a short-part reversing device. Background Technology

[0002] In modern manufacturing, the production of many precision components involves the machining of short, thin parts. These parts are widely used in electronics, aerospace, automotive engineering, and many other fields, such as miniature shafts in electronic devices, small connecting parts in aircraft engines, and inner rings of small bearings. In many cases, to meet the functional requirements of the product, some short, thin parts need to be machined at both ends, which inevitably involves reversing operations during the machining process.

[0003] Short and thin parts, due to their unique dimensional characteristics—relatively small diameter and length—pose significant challenges to reversing operations during processing. Their small size makes it difficult for traditional automated reversing equipment to accurately grasp and position them. Firstly, their tiny size makes them prone to being loosely clamped or damaged during gripping. Insufficient clamping force may cause the part to detach during reversing, leading to processing interruptions or even equipment damage; while excessive clamping force may cause indentations, deformation, or other damage to the part's surface, affecting product quality. Secondly, due to their small size, even minor deviations during positioning can significantly reduce subsequent processing accuracy, making it difficult for automated equipment to meet high-precision reversing requirements.

[0004] Given the difficulties of automated reversing, the reversing of short and thin parts in many production scenarios currently relies heavily on manual labor. While manual reversing allows for relatively precise operations based on operator experience, this method has significant drawbacks. First, manual operation is inefficient. Operators need to pick up, reverse, and reposition each short and thin part individually, a time-consuming process that significantly impacts production efficiency and increases costs, especially in large-scale production. Second, the repetitive nature and fatigue of manual reversing make it difficult to maintain a high level of attention and precision. This makes short and thin parts highly susceptible to collisions with surrounding tooling, fixtures, or other objects during reversing, resulting in surface scratches, deformation, and other damage. This increases the product defect rate, impacting the company's economic benefits and product reputation. Utility Model Content

[0005] To improve production efficiency and yield, this application provides a short-piece reversing device.

[0006] This application provides a short-component commutation device, which adopts the following technical solution:

[0007] A short component reversing device includes a reversing cylinder for inserting short components, a reversing drive for controlling the reversing of the reversing cylinder, and a reversing push assembly for pushing short components out of the reversing cylinder. The reversing cylinder is provided with a material passage through which short components can pass.

[0008] In one embodiment, at least one end of the feed channel is provided with a damping element for keeping the short piece fixed in the feed channel.

[0009] In one embodiment, the damping element is an elastic element disposed on the inner wall of the material passage.

[0010] In one embodiment, the elastic element is a sealing ring embedded in the inner wall of the material passage, or multiple elastic protrusions embedded in the inner wall of the material passage.

[0011] In one embodiment, the material passage has a flared opening at one end where a damping element is provided.

[0012] In one embodiment: the reversing pusher assembly includes a reversing pusher that can be inserted into and pass through the material passage, a reversing power component for pushing the reversing pusher to move axially, a first reversing mounting seat for mounting the reversing power component, and a second reversing mounting seat for mounting the first reversing mounting seat. The mounting position of the first reversing mounting seat on the second reversing mounting seat is adjustable. The first reversing mounting seat is provided with a reversing guide seat for guiding the reversing pusher.

[0013] In one embodiment: the reversing push rod includes a first reversing rod connected to the reversing power component and a second reversing rod connected to the first reversing rod; the reversing guide seat is provided in two parts, and the first reversing rod and the second reversing rod are respectively inserted into the two reversing guide seats.

[0014] The first reversing rod is provided with a reversing limiting ring at one end where it connects to the second reversing rod, and the second reversing rod is provided with a reversing return spring. The two ends of the reversing return spring abut against the reversing limiting ring and the reversing guide seat, respectively.

[0015] The first reversing rod is provided with an elastic compensation telescopic structure at one end connected to the reversing power component. The telescopic rod of the reversing power component abuts against the elastic compensation telescopic structure, and the initial elastic tendency force of the elastic compensation telescopic structure is greater than that of the reversing reset spring.

[0016] In one embodiment: the elastic compensation telescopic structure includes a slidably mounted commutator slider in the first commutator rod and a commutator energy storage spring in the first commutator rod in a compressed state. The end of the first commutator rod is provided with a commutator insertion hole with a diameter smaller than that of the commutator slider, and the telescopic rod of the commutator power component is inserted into the commutator insertion hole.

[0017] In one embodiment: the reversing device further includes a two-axis slide, and the reversing power component and the second reversing mounting base are mounted on the two-axis slide.

[0018] In summary, this application has the following beneficial effects: By using a reversing cylinder to grip short parts, damage to the surface of the short parts during gripping can be effectively avoided, thus improving the yield. When reversal is required, it is only necessary to control the reversing cylinder to rotate 180 degrees, and then push the short parts out through the reversing pusher assembly, effectively improving production efficiency.

Detailed Implementation

[0024] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0025] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0026] Example 1: A short-component commutation device, such as Figure 1 As shown, it includes a two-axis slide 100, a reversing cylinder 200, a reversing drive 300, and a reversing pusher assembly 400.

[0027] The reversing cylinder 200, the reversing drive component 300, and the reversing pusher assembly 400 are all mounted on the two-axis slide table 100, which is mounted on a lathe. The two-axis slide table 100 enables control in the X and Y axes. The two-axis slide table 100 preferably adopts a lead screw sliding structure to ensure driving accuracy.

[0028] like Figure 2 and Figure 3 As shown, the reversing drive 300 is a rotary cylinder, and the reversing cylinder 200 is fixed on the turntable of the reversing drive 300. The reversing drive 300 controls the reversing cylinder 200 to rotate 180 degrees to change direction.

[0029] The reversing cylinder 200 is provided with a material passage 210 through which short and thin parts can pass. At least one end of the material passage 210 is provided with a damping element 220 for keeping the short and thin parts fixed in the material passage 210. The end of the material passage 210 with the damping element 220 is the end for inserting the short and thin parts. In order to facilitate the insertion of the short and thin parts, the opening of the end of the material passage 210 with the damping element 220 is set as a flared opening 230.

[0030] It should be noted that when only one end is equipped with a damping element 220, the reversing cylinder 200 needs to be reset by 180 degrees after each push of the short shaft. However, if both ends are equipped with damping elements 220, the reset action is not required.

[0031] The damping element 220 is an elastic element disposed on the inner wall of the material passage 210. The elastic element can be a sealing ring embedded in the inner wall of the material passage 210, or multiple elastic protrusions embedded in the inner wall of the material passage 210. In this embodiment, a sealing ring is used as an example. In addition, since the short part is relatively short, in order to ensure that the short part can be fixed by the damping element 220, it is preferable to place the damping element 220 at the docking position between the material passage 210 and the flared opening 230.

[0032] The reversing pusher assembly 400 is used to push short, thin parts out of the reversing cylinder 200, see reference. Figure 2 The reversing pusher assembly 400 includes a reversing push rod 420 that can be inserted into and pass through the material passage 210, a reversing power member 410 for pushing the reversing push rod 420 axially, a first reversing mounting seat 430 for mounting the reversing power member 410, and a second reversing mounting seat 440 for mounting the first reversing mounting seat 430.

[0033] The end of the reversing push rod 420 is preferably made of plastic or rubber.

[0034] The second reversing mounting base 440 is fixedly mounted on the two-axis slide table 100. The first reversing mounting base 430 is slidably mounted on the second reversing mounting base 440 and fixedly connected by bolts. In this way, the installation position of the first reversing mounting base 430 on the second reversing mounting base 440 can be adjusted. By adjusting the position of the first reversing mounting base 430 on the second reversing mounting base 440, the reversing push rod 420 and the material passage 210 are coaxially aligned.

[0035] The first reversing mounting base 430 is provided with a reversing guide seat 450 for guiding the reversing push rod 420. The reversing guide seat 450 is provided with a bearing for the reversing push rod 420 to pass through, ensuring that the reversing push rod 420 is straight and can be inserted into the material passage 210.

[0036] In use, the reversing cylinder 200 grips the short shaft and rotates to change direction. Then, the reversing push rod 420 pushes the short shaft to move towards the other end of the feed channel 210 until the short shaft is pushed out of the feed channel 210. Therefore, it is only necessary to position the reversing cylinder 200 in front of the lathe fixture when pushing out the short shaft.

[0037] Example 2: Figure 4 As shown, the difference from Embodiment 1 is that the reversing push rod 420 includes a first reversing rod 421 connected to the reversing power member 410 and a second reversing rod 422 connected to the first reversing rod 421. In this embodiment, the first reversing rod 421 and the second reversing rod 422 are integrally formed.

[0038] Two reversing guide seats 450 are provided, and a first reversing rod 421 and a second reversing rod 422 are respectively inserted into the two reversing guide seats 450. A reversing limiting ring 423 is provided at the end where the first reversing rod 421 connects to the second reversing rod 422. A reversing return spring 424 is sleeved on the second reversing rod 422, and the two ends of the reversing return spring 424 abut against the reversing limiting ring 423 and the reversing guide seat 450 respectively.

[0039] One end of the first commutator 421 connected to the commutator power member 410 is provided with an elastic compensation telescopic structure 460. The elastic compensation telescopic structure 460 includes a commutator slider 461 slidably installed in the first commutator 421 and a commutator energy storage spring 462 located in the first commutator 421 in a compressed state. The end of the first commutator 421 is provided with a commutator insertion hole with a diameter smaller than that of the commutator slider 461. The telescopic rod of the commutator power member 410 is inserted into the commutator insertion hole.

[0040] The reversing push rod 420 is moved by the abutting of the telescopic rod of the reversing power component 410 against the elastic compensation telescopic structure 460. The initial elastic tendency force of the elastic compensation telescopic structure 460 is greater than that of the reversing reset spring 424. In this embodiment, to increase the initial elastic tendency force of the reversing energy storage spring 462, the reversing energy storage spring 462 is in a compressed state when installed within the first reversing rod 421, while the sliding stroke of the reversing slider 461 within the first reversing rod 421 is fixed, thus maintaining the initial compressed state of the reversing energy storage spring 462.

[0041] Thus, during use, the telescopic rod of the reversing power component 410 abuts against the reversing slider 461, pushing the reversing push rod 420 to move axially. At this time, the reversing return spring 424 is compressed. When the second reversing rod 422 is inserted into the reversing cylinder 200 to push out the short shaft, the optimal state of the reversing energy storage spring 462 is not compressed until the short shaft is pushed out. When the short shaft is pushed out and abuts against the lathe fixture, the reversing power component 410 continues to control the extension, and the reversing return spring 424 is compressed for compensation. On the one hand, this can better ensure that the short shaft is pushed into place, and on the other hand, it can avoid damage to the short shaft.

[0042] After completion, the telescopic rod of the reversing power component 410 retracts, and the reversing push rod 420 is reset under the action of the reversing reset spring 424.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
