[0025] Embodiment 1

[0026] As Figure 1As shown in the figure, this embodiment proposes an automatic positioning tooling for escalator chain fixing clips, which includes a positioning core 1, a positioning block 2, a supporting block 3, a top block 4, a sliding block 5, a linear guide rail 6, a linear driving mechanism 7, a fixing clip limiting block 8, a step shaft ejecting mechanism 9, a step shaft tightening mechanism 10, a mechanism control valve 11, a mechanism control valve 12, and a mechanism control valve 13. Among them, the linear guide rail 6 is arranged on the platform, and the supporting block 3, the fixing block 2, and the step shaft ejecting mechanism 9 are symmetrically arranged at both ends of the linear guide rail 6 in sequence. The side of the supporting block 3 away from the linear guide rail 6 leans against the fixing block 2; at one end of the linear guide rail 6, away from the step shaft ejecting mechanism 9, the positioning core 1 is provided; at the other end of the linear guide rail 6, away from the step shaft ejecting mechanism 9, the step shaft tightening mechanism 10 is provided;

[0027] The linear guide rail 6 is provided with a sliding block 5 and a top block 4 that can slide on the linear guide rail 6. The linear driving mechanism 7 is provided between both sides of the sliding block 5 and a top block 4 respectively;

[0028] The supporting block 3 includes a supporting groove 301 located at the top of the supporting block 3 for carrying the step shaft 101, a limiting surface 302 and a fixing limiting block 8 located on the side of the supporting block 3. The fixing limiting block 8 is arranged below the limiting surface 302. The backing plate 401 on the top block 4 is arranged opposite to the side of the supporting block 3. The guiding groove 402 for carrying the step shaft 101 is provided on the backing plate 401. The positioning core 1, the guiding groove 402, and the supporting groove 301 are located on the same axis;

[0029] The mechanism control valve 11 is connected to the step shaft tightening mechanism 10, the mechanism control valve 12 is connected to the linear driving mechanism 7, and the mechanism control valve 13 is connected to the step shaft ejecting mechanism 9.

[0030] The steps of fastening the fixing clip 102 to the step shaft 101 according to the tooling of this embodiment include:

[0031] Step 1: After threading the step shaft 101 through the fixing clip 102, place it stably on the supporting groove 301 of the supporting block 3 and the guiding groove 402 of the backing plate 401.

[0032] Step 2: Operate the mechanism control valve 11 to make the ejector rod of the step shaft tightening mechanism 10 eject towards the end of the step shaft 101, so as to axially fix the step shaft 101 between the positioning core 1 and the ejector rod of the step shaft tightening mechanism 10.

[0033] Step 3: Operate the mechanism control valve 12 to control the ejector rod of the linear driving mechanism 7 to eject the top block 4. The top block 4 moves outward along the linear guide rail 6, that is, moves towards the two end parts of the step shaft 101. The backing plate 401 on the top block 4 pushes the fixing clip 102 against the limiting surface 302 on the side of the supporting block 3 to clamp and fix the fixing clip 102.

[0034] Step 4: Use a pneumatic wrench to tighten the bolts on the fixing clip 102. Through the action of the bolts, the fixing clip 102 is clamped and fixed on the step shaft 101.

[0035] Step 5: Loosen mechanism control valve 11 and mechanism control valve 12, and operate mechanism control valve 13. Push up the step shaft 101 through the ejector cylinder 9, so as to lift the processed step shaft assembly, that is, lift the step shaft 101 with the fixing clip 102 fastened, which is convenient for workers to take.

[0036] In the prior art, the bushing needs to be positioned according to the buckle size of the step first and then the fixing clip is fastened. This solution can only be assembled inside the escalator, and the operating space is limited. Adopting the technical solution of this embodiment, after the fixing clip 102 is fixed, during on-site assembly, only 1 bushing needs to be sleeved on the outside of each of the 2 fixing clips 102. After the step buckle and the bushing are fastened, the step is fixed on the bushing. Since the fixing clip 102 has been fixed on the step shaft 101 in advance, the step is also completely fixed at this time, avoiding the inconvenience of workers working in the limited space inside the escalator.

[0037] According to the step shaft 101 of different sizes, process the positioning core 1 with corresponding dimensions to ensure the stability of the dimension for the positioning core 1 to position the step shaft 101, and further ensure the stable positioning of the step shaft 101.

[0038] According to the dimensional position of the fixing clip 102 on the step shaft 101, adjust the position of the supporting block 3 on the tooling. The supporting block 3 leans against one side of the positioning block 2, and the supporting block 3 is fixed on the operating table of the tooling by screws. The improvement of the positioning accuracy is achieved by the cooperation of the positioning core 1 and the supporting block 3. After the position of the supporting block 3 on the tooling is adjusted and determined, the positioning block 2 and the screws thereon are used to position and strengthen the fixing of the supporting block 3, improving the positioning accuracy, so as to ensure that the distance dimension between the two fixing clips 102 on the step shaft 101 meets the requirements. Compared with the prior art, the test data characterization under the condition that the step shaft 101 has the same specification shows that the technical solution of this embodiment improves the positioning accuracy by 50%. The difference in the specifications of the step shaft 101 is mainly the difference in the length of the step shaft, which makes the distance from the fixing clip 102 to the edge of the step shaft 101 different. The relative distance between the two fixing clips 102 is fixed, and the structure at the fixed position of the fixing clip 102 on the step shaft 101 is a straight rod. In this solution, the linear drive mechanism 7, the fixing clip limit block 8, the step shaft ejecting mechanism 9 and the step shaft tightening mechanism 10 can adopt cylinders, and other drive mechanisms can also be used for replacement, such as changing the air pressure to oil pressure, changing the cylinder to an oil cylinder, or changing the cylinder to an electric cylinder.

[0039] As an alternative embodiment, the guiding groove 402 and the supporting groove 301 are in the shape of an arc, V-shaped or square, which can all provide space for carrying the step shaft 101 and are convenient for carrying the step shaft 101.

[0040] As an alternative embodiment, when the step shaft 101 passing through the fixing clip 102 is placed on the guiding groove 402 and the supporting groove 301, after the linear driving mechanism 7 makes a linear pushing action, the top of the fixed limit block 8 abuts against the bottom edge of the fixing clip 102. The linear pushing action of the linear driving mechanism 7 realizes the positioning of the fixing clip 102 along the axial direction of the step shaft 101. Through this solution, the positioning of the fixing clip 102 along the axial direction perpendicular to the step shaft 101 is realized, so as to facilitate the tightening of the bolts on the fixing clip 102, and further realize the technical effect of fixing the fixing clip 102 on the step shaft 101.

[0041] As an alternative embodiment, a groove for carrying the end of the step shaft 101 is provided at one end of the positioning core 1 opposite to the step shaft 101. It is used for positioning one end of the step shaft 101, and further cooperates with the ejector rod of the step shaft tightening mechanism 10 to realize the axial positioning of the step shaft 101.

[0042] As an alternative embodiment, it further includes a platform 220, and the positioning core 1, the step shaft ejecting mechanism 9, the fixing block 2, the supporting block 3, the linear guide rail 6, the step shaft tightening mechanism 10, the mechanism control valve 11, the mechanism control valve 12 and the mechanism control valve 13 are all arranged on the platform 220; it is convenient to install and fasten the fixing clip 102 on the step shaft 101 on this platform 220.

[0043] As an alternative embodiment, the positioning core 1 is fixed on the L-shaped backing plate 103, and the L-shaped backing plate 103 is fixed on the platform 220. Through this fixing method, the positioning core 1, the guiding groove 402 and the supporting groove 301 can be located on the same axis, and at the same time, the positioning core 1 is indirectly fixed on the platform 220, which is convenient to cooperate with the ejector rod of the step shaft tightening mechanism 10 to realize the axial positioning of the step shaft 101.

[0044] As an alternative embodiment, the step shaft tightening mechanism 10 is fixed on the L-shaped backing plate 103, and the L-shaped backing plate 103 is fixed on the platform 220. In order to realize the cooperation between the ejector rod of the step shaft tightening mechanism 10 and the positioning core 1, the axial positioning of the current step shaft 101 is realized.

[0045] As an alternative embodiment, an ejector plate 901 is provided on the ejector rod of the step shaft ejecting mechanism 9. When the fixing clip 102 is fastened on the step shaft 101, the ejector rod of the step shaft ejecting mechanism 9 acts on the step shaft 101 through the ejector plate 901, and ejects the step shaft 101 from between the ejector rod of the step shaft tightening mechanism 10 and the positioning core 1 along the direction perpendicular to the axial direction of the step shaft 101, that is, the vertical direction, so as to facilitate manual removal.

[0046] As an alternative embodiment, a groove plate is provided on the ejector plate 901, which is convenient for carrying the step shaft 101. Further, the ejector rod of the step shaft ejecting mechanism 9 can act on the ejector plate 901 and the groove plate to act on the step shaft 101 and eject the step shaft 101.

[0047] As an alternative embodiment, the ejector rod of the step shaft tightening mechanism 10, the positioning core 1, the guide groove 402 and the supporting groove 301 are all located on the same axis. This is convenient for placing and carrying the step shaft 101. Further, the positioning core 1 and the ejector rod of the step shaft tightening mechanism 10 cooperate to realize the axial positioning of the step shaft 101.

What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the gist of the present invention, they shall fall within the protection scope of the present invention.
