Description

Technical Field

[0001] This utility model relates to the field of parts processing, and in particular to an automatic alignment mechanism for multi-station divider parts. Background Technology

[0002] To improve production efficiency, multi-station part division has become the mainstream method, which involves setting up multi-station dividers to divide parts. However, for automatic part alignment configuration, independent alignment mechanisms are often used, meaning that each station corresponds to an independent alignment device. While this architecture meets basic positioning requirements, it increases equipment space occupancy, especially in the processing of small, precision parts. The redundancy of mechanisms created by multiple stations increases the space required for operation, and the simultaneous sequential control of multiple alignment mechanisms is complex, increasing equipment complexity. If they cannot respond synchronously, it can cause part processing errors, affect part processing accuracy, and even damage the parts. Utility Model Content

[0003] Therefore, it is necessary to provide an automatic alignment mechanism for multi-station divider parts to address the redundancy and synchronous response issues of existing independent alignment mechanisms.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] An automatic alignment mechanism for multi-station divider parts mainly consists of a base plate, a limit block, and an alignment mechanism.

[0006] Two limit blocks form a set to support the two ends of the part respectively, and multiple sets of limit blocks are equidistantly arranged on the top surface of the base plate along the length of the base plate.

[0007] The alignment mechanism includes an alignment plate, end caps, and limiting protrusions. The alignment plate is slidably mounted on the top of the base plate along the length and width of the base plate, and faces the limiting block. The number of end caps is the same as the number of limiting blocks and they are arranged one-to-one on the alignment plate and are integrated with the alignment plate. The end caps are open at the end facing the limiting block and the end face is flush with the alignment plate. The limiting protrusions are slidably mounted on the circumferential surface of the end caps and limit the movement of parts entering the end caps.

[0008] Furthermore, the limiting protrusion includes a top protrusion and a bottom protrusion; multiple top protrusions are connected to a first connecting rod, which is located above the end cap and driven by a first telescopic cylinder; multiple bottom protrusions are connected to a second connecting rod, which is located below the end cap and driven by a second telescopic cylinder, with the first and second telescopic cylinders located on the side of the alignment plate away from the limiting block.

[0009] Furthermore, the limiting protrusion also includes a side protrusion; the opposite sides of adjacent end caps are provided with side protrusions, and a push rod is provided between the two side protrusions. The side wall of the push rod contacts the end of the side protrusion, and the push rod gradually shrinks from top to bottom and its top is fixedly connected to the first connecting rod.

[0010] Furthermore, the limiting protrusion also includes a side protrusion; the opposite sides of adjacent end caps are provided with side protrusions, and a push rod is provided between the two side protrusions. The side wall of the push rod contacts the end of the side protrusion, and the push rod gradually expands from top to bottom and is fixedly connected to the second connecting rod at the bottom.

[0011] Furthermore, the limiting protrusion is a protrusion made of a flexible material.

[0012] Furthermore, the alignment plate and the top of the base plate are connected by a two-axis slide module.

[0013] Furthermore, the end of the lateral protrusion located outside the end cap is elastically connected to the outer wall of the end cap.

[0014] Furthermore, the internal dimensions of the end cap are adapted to the end dimensions of the part, and the length of the end cap is at most one-quarter of the length of the part.

[0015] Furthermore, the area with the limiting block at the top of the base plate extends outward to form a raised section, and the total height of the raised section and the height of the limiting block are adapted to the height of the end cap.

[0016] Furthermore, the limiting block and the raised part are detachably connected.

[0017] Compared with the prior art, the beneficial effects of this utility model include:

[0018] By aligning parts on multiple limit blocks simultaneously through a single alignment mechanism, automatic alignment of parts on multiple limit blocks is achieved by one alignment mechanism, avoiding redundancy and errors in the synchronous response of multiple alignment mechanisms; the overall structure is simple and easy to maintain.

[0027] Example 1

[0028] like Figure 1 As shown in the figure, this embodiment introduces an automatic alignment mechanism 3 for multi-station divider parts, which mainly consists of a base plate 1, a limiting block 2, and an alignment mechanism 3. In order to facilitate the installation of the alignment mechanism 3, the area on the base plate 1 where the alignment mechanism 3 is installed is recessed by a certain distance to provide space for the installation of the alignment mechanism 3.

[0029] Multiple sets of limiting blocks 2 are equidistantly arranged on the top surface of the non-sunken area of ​​the base plate 1 along the length direction. Each set of limiting blocks 2 consists of two blocks, which are supported at both ends of the part by a double-point support structure to form a stable positioning reference surface.

[0030] like Figure 2As shown, the alignment mechanism 3 includes an alignment plate 31, end caps 32, and limiting protrusions. The alignment plate 31 is located on the top of the base plate 1, which slides precisely in two dimensions along the length and width of the base plate 1. The alignment plate 31 is connected to the base plate 1 via a two-axis slide module, enabling the alignment plate 31 to slide on the base plate 1. The alignment plate 31 is mounted on the movable end of the two-axis slide module, and the bottom of the alignment plate 31 is in contact with the top of the base plate 1. Alternatively, a cross ball bearing guide can be used to achieve sliding of the base plate 1, or other mechanisms that can achieve two-dimensional sliding, such as the combination of a linear slide module and a cylinder. The working surface of the alignment plate 31 forms an orthogonal spatial layout with the limiting block group 2. Its surface is integrated with end caps 32 matching the number of limiting block group 2. Each end cap 32 is rigidly connected to the alignment plate 31 using an integrated casting process, or the connection can be achieved by welding. The end cap 32 is open at one end facing the limiting block 2 and its end face is flush with the alignment plate 31. The internal cavity is designed according to the geometric features of the end of the part and its axial length is controlled within 1 / 4 of the total length of the part.

[0031] The base plate 1 is provided with a stepped raised part. The raised height is parametrically designed so that the opening plane of the end cap 32 and the support surface of the limit block 2 are at the same height in the Z direction. The limit block 2 and the raised part are detachably connected by bolts or by snap-fit.

[0032] like Figure 2-5 As shown, the limiting protrusion is slidably disposed on the circumference of the end cap 32 and limits the movement of parts entering the end cap 32. The limiting protrusion includes a top protrusion 33, a bottom protrusion 34, and a side protrusion 35; multiple top protrusions 33 are connected to a first telescopic cylinder 38 via a first connecting rod 36; multiple bottom protrusions 34 are connected to a second telescopic cylinder 39 via a second connecting rod 37. The first telescopic cylinder 38 and the second telescopic cylinder 39 are disposed on the side of the alignment plate 31 opposite to the limiting block 2. Side protrusions 35 are provided on opposite sides of adjacent end caps 32, and a push rod 310 is disposed between the two side protrusions 35. The side wall of the push rod 310 contacts the end of the side protrusion 35, and the push rod 310 gradually retracts from top to bottom and its top is fixedly connected to the first connecting rod 36. The limiting protrusion is a protrusion made of a flexible material, such as polyurethane. Alternatively, one end located inside the end cap 32 may be made of a flexible material. One end of the side protrusion 35 located outside the end cap 32 is elastically connected to the outer wall of the end cap 32. Specifically, the end of the side protrusion 35 located outside the end cap 32 extends radially to form an annular protrusion. A spring is provided between the annular protrusion and the outer wall of the end cap 32 to push the side protrusion 35 outward. A corresponding support portion is provided on the outer side of the positioning plate 31 to support the side protrusion 35. Alternatively, the extended end of the side protrusion 35 can use a spring steel sheet to achieve elastic coupling with the outer wall of the end cap 32.

[0033] During operation, the end cap 32 on the comparison plate is initially misaligned with the end of the part. Then, the alignment plate 31 is driven to move towards the limiting block 2, pushing the part located on the limiting block 2 forward. Subsequently, the alignment plate 31 moves along the length of the base plate 1, causing the end cap 32 to move to the end of the part. The alignment plate 31 continues to move forward, so that the end of the part is located inside the end cap 32. Then, the limiting protrusion moves into the end cap 32, closely adhering to the end of the part. Subsequently, the alignment plate 31 moves backward, driving the part to move, thus realizing the automatic alignment operation of multiple parts.

[0034] This embodiment uses the alignment mechanism 3 to simultaneously perform alignment operations on the parts on multiple limit blocks 2, so that one alignment mechanism 3 can automatically align the parts on multiple limit blocks 2, avoiding redundancy of mechanisms and the problem of errors in the synchronous response of multiple alignment mechanisms 3; the overall structure is simple and easy to maintain.

[0035] Example 2

[0036] This embodiment introduces an automatic alignment mechanism 3 for multi-station divider parts, which is basically the same in structure as the automatic alignment mechanism 3 for multi-station divider parts introduced in Embodiment 1. The difference is that in this embodiment, the push rod 310 gradually expands from top to bottom and its bottom is fixedly connected to the second connecting rod 37.

[0037] This embodiment has the same beneficial effects as Embodiment 1.

[0038] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
