Figure 1 As shown, there is a bent edge on one side, and the straight sections on the left and right sides are of different lengths, requiring differentiation between the left and right parts. This workpiece requires fixture positioning and clamping before 3D laser cutting. However, due to its unique shape, positioning is difficult. Summary of the Invention

[0003] In view of this, in order to solve the problems of the prior art, the present invention provides a positioning device suitable for escalator cover plates, which can effectively and accurately position and clamp the outer cover plates of handrail brackets, facilitating subsequent processing.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

The arc segment positioning assembly includes an outer positioning plate for abutting against the outer side of the arc segment of the cover plate, an inner positioning plate for abutting against the inner side of the arc segment of the cover plate, and a first clamping mechanism for clamping the bent edge of the arc segment. The extension segment positioning assembly includes a limit block, a support block, and a second clamping mechanism for clamping the bent edge of the extension segment.

[0006] The outer positioning plate mates with the outer side of the arc segment, while the inner positioning plate mates with the inner side of the arc segment. The arc segment is clamped between the inner and outer positioning plates. The curved edge of the arc segment is clamped by the first clamping mechanism, while the extension segment is clamped by the second clamping mechanism and the stop block. Two sets of extension segment positioning assemblies are provided to clamp the left and right cover extensions. This arrangement effectively positions and clamps the outer cover of the escalator head handrail bracket.

[0010] According to some preferred embodiments of the present invention, the inner positioning plate includes a connecting plate for connecting to the slider and an arc plate for contacting the arc segment, wherein the arc plate is wider than the connecting plate. The wider the arc segment, the greater the contact area with the cover plate, resulting in better positioning and clamping effects.

[0011] According to some preferred embodiments of the present invention, the limit block is located outside the extension section, the support block is located below the bent edge of the extension section, and the limit block and the support block are arranged perpendicularly. The limit block is used to support the outside of the extension section, and the support block is located below the bent edge of the extension section.

[0012] According to some preferred embodiments of the present invention, at least two first clamping mechanisms are provided on the tooling plate, the two or more first clamping mechanisms being symmetrically arranged about the centerline of symmetry of the arc segment, and the first clamping mechanisms comprising horizontal and vertical quick-action clamps.

[0014] According to some preferred embodiments of the present invention, the second clamping mechanism further includes a guide sleeve mounted on the pull rod of the push-pull quick clamp and a clamping plate connected to the guide sleeve, wherein the guide sleeve is used to rotate the clamping plate around the pull rod. By providing the guide sleeve, the clamping plate can be rotated, which facilitates removal after the cover plate is processed. The shortest distance between the clamping plate and the limit block matches the thickness of the extension section so that the extension section is clamped between the clamping plate and the limit block. A pressure block is also provided on the clamping plate to press the bent edge of the extension section against the support block.

[0015] According to some preferred embodiments of the present invention, the symmetric centerline of the outer positioning plate and the symmetric centerline of the inner positioning plate coincide with the symmetric centerline of the cross-section of the arc segment, and the handle is located on this symmetric centerline. The arc segment is arranged in an arc shape, and its center coincides with the center of the circle corresponding to the outer positioning plate, the center of the arc plate in the inner positioning plate, and the center of the circle formed by the clamping points of the multiple first clamping mechanisms. This allows the escalator cover positioning device of the present invention to effectively position and clamp the outer cover of the handrail bracket.

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. 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 should fall within the scope of protection of the present invention.

[0024] The outer cover of the head handrail bracket of the escalator includes an arc section 31 and an extension section 32. One side of the arc section 31 and the extension section 32 has a bent edge 33. Figure 1-4 The escalator cover positioning device of this embodiment is used to position and clamp the cover, and includes a frame 1, a tooling plate 2 mounted on the frame 1, and an arc segment positioning assembly and an extension segment positioning assembly. The arc segment positioning assembly is used to position and clamp the arc segment 31 and its bent edge 33, while the extension segment positioning assembly is used to position and clamp the extension segment 32 and its bent edge 33. In this embodiment, two identical extension segment positioning assemblies are provided to accommodate positioning and machining of the left and right cover components without requiring any adjustments.

[0025] The arc segment positioning assembly includes an outer positioning plate 4 for abutting the outer side of the cover plate arc segment 31, an inner positioning plate 5 for abutting the inner side of the cover plate arc segment 31, and a first clamping mechanism for clamping the bent edge 33 of the arc segment. The outer positioning plate 4 matches the outer side of the arc segment 31, and the inner positioning plate 5 matches the inner side of the arc segment 31. The arc segment 31 is clamped between the inner positioning plate 5 and the outer positioning plate 4, and the bent edge 33 of the arc segment 31 is clamped by the first clamping mechanism. The outer positioning plate 4 in this embodiment is composed of a first outer positioning plate 414, a second outer positioning plate 424, and a third outer positioning plate 434. The first clamping mechanism is a horizontal vertical quick clamp 6.

[0026] The tooling plate 2 is provided with a moving assembly 12 for driving the inner positioning plate 5 to move. The moving assembly 12 includes a guide rail provided on the tooling plate 2, a slider cooperating with the guide rail, and a driving mechanism for driving the slider to slide along the guide rail. The inner positioning plate 5 is fixedly connected to the slider. The driving mechanism of this embodiment includes a screw rod passing through the slider and a handle 13 for driving the screw rod to rotate. The screw rod is threadedly connected to the slider. When the inner positioning plate 5 needs to be moved, the handle 13 is rotated to drive the screw rod to rotate, the slider moves, and the inner positioning plate 5 moves, which is convenient and quick. A locking mechanism for fixing the position of the handle 13 is also provided on the handle 13, such as a quick-release rod or other structure, to prevent the handle from being accidentally touched, resulting in inaccurate positioning.

[0027] The inner positioning plate 5 moves along the symmetrical centerline 14 of the arc segment 31. Specifically, the moving assembly 12 drives the inner positioning plate 5 back and forth along this symmetrical centerline 14, enabling the inner positioning plate 5 to cooperate with the outer positioning plate 4 to accurately position and clamp the cover plate's arc segment 31. The inner positioning plate 5 includes a connecting plate 51 for connection to the slider and an arc plate 52 for contacting the arc segment 31. The arc plate 52 is wider than the connecting plate 51. The wider the arc segment 31, the greater the contact area with the cover plate's arc segment 31, resulting in better positioning and clamping.

[0028] In this embodiment, two sets of first clamping mechanisms are provided on both sides of the inner positioning plate 5 for clamping the bent edge 33 of the arc segment. The four first clamping mechanisms are symmetrically arranged about the symmetry centerline 14 of the arc segment 31. The symmetry centerline 14 of the outer positioning plate 4 and the symmetry centerline 14 of the inner positioning plate 5 coincide with the symmetry centerline 14 of the arc segment 31, and the handle 13 is located on the symmetry centerline 14. The arc segment 31 is arranged in an arc shape, and its center coincides with the center of the circle corresponding to the outer positioning plate 4, the center of the circle corresponding to the arc plate 52 in the inner positioning plate 5, and the center of the circle formed by the clamping points of the multiple first clamping mechanisms. This enables the escalator cover positioning device of this embodiment to effectively position and clamp the outer cover of the handrail bracket.

[0029] The extension section positioning assembly includes a limit block 8, a support block 9, and a second clamping mechanism for clamping the extension section bend 33. The limit block 8 is located outside the extension section 32, and the support block 9 is located below the extension section bend 33. The limit block 8 and the support block 9 are arranged perpendicularly.

[0030] In this embodiment, two sets of extension segment positioning assemblies are provided to clamp the left and right cover extension segments 32. The two sets of extension segment positioning assemblies are symmetrically arranged about the symmetry centerline 14 of the arc segment 31. A different number of second clamping mechanisms can also be provided depending on the length of the extension segment 32 to position and clamp the extension segment 32 and the extended segment bent edge 33.

[0031] The second clamping mechanism in this embodiment includes a push-pull quick-action clamp 7, a guide sleeve 10 that fits over the pull rod of the push-pull quick-action clamp 7, and a clamping plate 11 connected to the guide sleeve 10. The guide sleeve 10 allows the clamping plate 11 to rotate, facilitating removal of the cover after machining. The minimum distance between the clamping plate 11 and the stop block 8 matches the thickness of the extension 32, thereby clamping the extension 32 between the clamping plate 11 and the stop block 8. A pressure block is also provided on the clamping plate 11 to press the bent edge 33 of the extension against the support block 9.

[0032] The following briefly describes the positioning process using the escalator cover positioning device in this embodiment:

[0033] Place the outer cover plate of the escalator head into the positioning device, and the cover plate is located on the tooling plate 2 to determine the height position. The outer positioning plate 4 positions the arc position of the cover plate. By turning the handle 13, the inner positioning plate 5 is driven to move to adjust the front and rear position of the inner positioning plate 5. The arc segment 31 is clamped between the outer positioning plate 4 and the inner positioning plate 5 to fix the front and rear position of the cover plate. Use the limit block 8 in the extension section positioning assembly to determine the opening size on both sides of the cover plate. Use the horizontal and vertical quick clamps 6 to clamp the bent edge 33 of the arc segment 31 so that it is close to the tooling plate 2, and the push-pull quick clamp 7 to clamp the bent edge 33 of the extension section 32 so that it is close to the support block 9 to fix the left and right positions for easy cutting. The clamp 11 on the push-pull quick clamp 7 can be rotated, which makes it easy to remove the cover plate after cutting is completed.

[0034] The escalator cover positioning device of the present invention can quickly and easily position and clamp the outer cover, facilitate three-dimensional cutting, and is simple to operate. Furthermore, the outer cover is divided into left and right parts. The escalator cover positioning device of the present invention allows the left and right parts to be produced on the same tooling, eliminating the need for tool change and facilitating operation.

[0035] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable people familiar with this technology to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of protection of the present invention.
