Description

Technical Field

[0001] The utility model relates to the technical field of step manufacturing, in particular to a step assembly tool. Background Art

[0002] Steps are important components of escalators and moving walkways, and their assembly quality directly affects the performance and safety of the entire system. With the rapid development of modern buildings and transportation facilities, higher requirements are placed on the accuracy, efficiency and flexibility of step assembly.

[0003] Traditional step assembly usually adopts manual positioning and fixing, which has the following problems:

[0004] 1. Low positioning accuracy: Manual positioning is easily affected by the operator's experience and skills, and it is difficult to ensure high accuracy and consistency.

[0005] 2. Poor adaptability: Steps of different specifications usually require different fixtures or tooling, which increases production costs and equipment replacement time.

[0006] In order to solve these problems, some improved step assembly tools have been developed. For example, some tools use pneumatic or hydraulic systems for clamping. Although the control accuracy of the clamping force is improved, the system is complex, the maintenance cost is high, and the flexibility is insufficient. Some other tools use electric adjustment mechanisms. Although they improve the convenience of adjustment, they are more expensive and difficult to operate in the case of power failure.

[0007] In addition, most existing step assembly tools tend to focus only on positioning and clamping in a single direction, and it is difficult to ensure the precise positioning of the steps in both the horizontal and vertical directions at the same time. This leads to a decrease in assembly accuracy and increases the workload of subsequent processing and adjustment.

[0008] Therefore, there is an urgent need for a step assembly tool that can solve the above problems at the same time, which can provide high-precision positioning and clamping, have good operability and adaptability, and be economical, practical and easy to maintain. Utility Model Content

[0009] In order to solve the above problems, the utility model discloses a step assembly tool.

[0010] In order to achieve the above purpose, the utility model provides the following technical solutions: a ladder assembly tool, comprising:

[0011] Base plate;

[0012] Transverse clamping assembly, comprising:

[0013] Two clamping blocks are arranged at two ends of the bottom plate, and the two clamping blocks are slidably matched with the bottom plate along the length direction of the bottom plate;

[0014] A bidirectional screw rod is inserted between the two clamping blocks, and the two clamping blocks are arranged on two thread segments of the bidirectional screw rod;

[0015] Longitudinal positioning assembly, comprising:

[0016] A plurality of limiting columns are arranged along the direction of the connection line of the two clamping blocks.

[0017] In the above scheme, the longitudinal positioning assembly further includes an eccentric wheel, which is rotatably mounted on the base plate and arranged opposite to the limiting column. The eccentric wheel can be rotated to clamp the side of the step to be assembled.

[0018] In the above solution, the limiting column is rotatably mounted on the base plate.

[0019] In the above scheme, the eccentric wheel is rotatably mounted on the base plate via a rotating shaft, and a shifting rod is connected to the outer end of the eccentric wheel, and the eccentric wheel is rotated via the shifting rod.

[0020] In the above solution, a plurality of supporting rollers are rotatably mounted on the surface of the bottom plate, and the supporting rollers are arranged perpendicular to the direction of the line connecting the two clamping blocks.

[0021] The solution of the embodiment of the present application realizes the precise positioning of the steps in two directions through the cooperation of the transverse clamping assembly and the longitudinal positioning assembly, which significantly improves the assembly accuracy. The design of the bidirectional screw allows the two clamping blocks to move synchronously, speeds up the adjustment speed, and improves the operating efficiency. Compared with pneumatic, hydraulic or electric systems, this purely mechanical structure is simpler and more reliable, easy to maintain, and reduces the cost of use.

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0026] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be used as limitations on the present invention. As used in the specification and appended claims of the present invention, the singular expressions "a", "an", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear contrary indication in the context.

[0027] References to "one embodiment" or "some embodiments" etc. described in this specification mean that one or more embodiments of the utility model include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0028] Example 1: Figure 1-3 As shown, a step assembly tool comprises:

[0029] Bottom plate 1;

[0030] Transverse clamping assembly, comprising:

[0031] Two clamping blocks 21 are arranged at both ends of the bottom plate 1, and the two clamping blocks 21 slide and cooperate with the bottom plate 1 along the length direction of the bottom plate 1; specifically, a linear slider can be used to cooperate with the T-slot of the bottom plate.

[0032] The bidirectional screw 22 is inserted between the two clamping blocks 21, and the two clamping blocks 21 are arranged on two thread segments of the bidirectional screw 22. In a possible implementation, the bidirectional screw 22 adopts a trapezoidal thread Tr30×6, with opposite left and right rotation directions, and a Φ100mm handwheel is provided at one end thereof for easy manual operation.

[0033] Longitudinal positioning assembly, comprising:

[0034] A plurality of limiting columns 31 are arranged along the line connecting the two clamping blocks 21 . The limiting columns 31 are rotatably mounted on the bottom plate 1 , and a bearing seat is provided at the bottom thereof, which can rotate 360°.

[0035] like Figure 2As shown, during operation, the operator first places one side of the step 5 against the limit column 31, and then turns the hand wheel of the bidirectional screw 22 according to the width of the step 5. Since the threads at both ends of the screw rotate in opposite directions, the two clamping blocks 21 will move toward or away from the middle synchronously. When the clamping blocks 21 contact both sides of the step, continue to tighten appropriately to achieve a stable clamping.

[0036] The transverse clamping assembly achieves symmetrical clamping through a bidirectional screw 22 to ensure that the step 5 is aligned in the center.

[0037] The longitudinal positioning assembly provides multi-point support through multiple adjustable limit columns 31 to ensure the accurate longitudinal position of the steps. Multiple rotatable limit columns 31 are arranged along the line connecting the clamping blocks 21, providing multi-point support and positioning for the steps. The rotatable design of the limit columns 31 allows the steps to be slightly adjusted during the positioning process, reducing the friction between the steps and the limit columns, and facilitating operation.

[0038] Example 2: Figure 2 As shown, the longitudinal positioning assembly further includes an eccentric wheel 32, which is rotatably mounted on the base plate 1 and arranged opposite to the limiting column 31. The eccentric wheel 32 is rotated so as to clamp the side of the step to be assembled.

[0039] During operation, the position of the limiting column 31 is adjusted so that one side edge of the step is against the limiting column 31. By turning the handle of the eccentric wheel 32, the outer circle of the eccentric wheel 32 gradually approaches the other side edge of the step. Due to the eccentric design, as the eccentric wheel 32 rotates, the distance between its outer circle and the edge of the step will gradually decrease until it contacts and applies appropriate pressure. When the appropriate clamping force is reached, the operator tightens the clamping nut of the locking mechanism to fix the position of the eccentric wheel 32 by friction. The design of the eccentric wheel 32 solves the problem of longitudinal positioning and clamping of the step. It not only improves the assembly accuracy, but also enhances the adaptability and ease of operation of the tooling.

[0040] In a possible implementation, the eccentric wheel 32 is rotatably mounted on the base plate 1 via a rotating shaft, and a lever 33 is connected to the outer end of the eccentric wheel 32, and the eccentric wheel 32 is rotated by the lever 33. The lever 33 serves as a handle for operating the eccentric wheel 32, allowing the operator to conveniently rotate the eccentric wheel. The lever 33 utilizes the principle of a lever to amplify the input force of the operator, making it easier to rotate the eccentric wheel 32.

[0041] Example 3: Figure 3 As shown, a plurality of supporting rollers 4 are rotatably mounted on the surface of the base plate 1 , and the supporting rollers 4 are arranged perpendicular to the direction of the line connecting the two clamping blocks 21 .

[0042] In this embodiment, the support rollers 4 provide direct support for the steps placed on the base plate 1, and can disperse the weight of the steps. Since the support rollers 4 can rotate, they can significantly reduce the friction between the steps and the base plate, making it easier to move and adjust the steps. The support rollers 4 are arranged perpendicular to the connecting line of the two clamping blocks 21, and this arrangement helps guide the steps to move in the correct direction.

[0043] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
