Description

Technical Field

[0001] The present application relates to the technical field of process equipment, and in particular to a multi-size positioning tool and a multi-size positioning system. Background Art

[0002] When producing different products on the same production line, multiple sets of tooling are required for replacement due to differences in product structure and size. When there are many identical toolings, the replacement process takes a lot of time, which can lead to the following problems:

[0003] Production delays: When tooling needs to be changed frequently, the replacement process takes up production line time, leading to production line stoppages and delays. This not only affects production efficiency, but may also affect delivery time and customer satisfaction. Increased labor costs: In order to complete the tooling change, manual intervention and operation time may be required. This increases labor costs and may lead to an increased risk of operator fatigue and errors. Increased production costs: Preparing multiple sets of tooling requires additional capital and resource investment. In addition, the maintenance, storage and management of tooling may also increase production costs. Product quality fluctuations: Frequent tooling changes may lead to fluctuations in product quality. Since the positioning and fixtures of each tooling may be different, the use of different tooling may lead to fluctuations in processing accuracy and product quality. Safety hazards: There may be safety risks and hidden dangers in the process of changing tooling. For example, operators may face the risk of tool injury, fixture pinching, etc.

[0004] In summary, the positioning tooling in the prior art has technical problems such as long changeover time and low production efficiency. Utility Model Content

[0031] In view of the shortcomings of the existing methods, this application proposes a multi-size positioning tool and a multi-size positioning system to solve the technical problems of long changeover time and low production efficiency in the existing technology.

[0032] In the first aspect, the embodiment of the present application provides a multi-size positioning tool, such as Figures 1 to 3 As shown, Figure 1 This is a schematic structural diagram of a multi-size positioning tool in an embodiment of the present application; Figure 2 This is a cross-sectional schematic diagram of a multi-size positioning tool in an embodiment of the present application; Figure 3 This is a schematic top view of a multi-size positioning tool in an embodiment of the present application.

[0033] A multi-size positioning tool comprises: a tool body 1, comprising a base 11 and a positioning cylinder 12, wherein the base 11 is fixedly connected to the positioning cylinder 12, and the base 11 and the positioning cylinder 12 have a through hole, and the through hole has a first positioning inner stop 101 and a second positioning inner stop 102 at one end facing the positioning cylinder 12, and the through hole has a main body positioning stop 103 at one end facing the base 11, and the inner diameter of the second positioning inner stop 102 is smaller than the inner diameter of the first positioning inner stop 101, and the second positioning inner stop 102 is located between the first positioning inner stop 101 and the main body positioning stop 103 in the axial direction.

[0034] In this embodiment, the first and second positioning inner stoppers 101, 102 are designed on the tool body 1. These first and second positioning inner stoppers 101, 102 have different inner diameters, allowing them to accommodate workpieces of different sizes. This improves the compatibility and applicability of the positioning tool without requiring replacement of the tool. This reduces changeover time during production, improves production efficiency, and avoids the quality fluctuations and safety risks that can arise from such changes.

[0035] In some embodiments of the present application, the axis of the first positioning inner stop 101 is offset from the axis of the second positioning inner stop 102 , and the axis of the first positioning inner stop 101 and the axis of the second positioning inner stop 102 are parallel to each other and not collinear.

[0036] In some embodiments of the present application, the inner diameter of the second positioning inner stop 102 is larger than the inner diameter of the main body positioning stop 103, and from the base 11 to the positioning cylinder 12, the inner diameters of the main body positioning stop 103, the second positioning inner stop 102, and the first positioning inner stop 101 expand outward in sequence.

[0037] In this embodiment, the sidewalls of the through-hole of the tool body 1 are stepped to form three different inner diameters. The inner diameters of the middle and bottom portions of the through-hole are equal to those of the tool body's positioning stop 103, used to secure the tool body 1 to a chain line. The inner diameters of the top and second top portions of the through-hole are equal to those of the first and second positioning inner stop 101, 102, respectively, and are oriented in the same direction, allowing for securing workpieces of varying sizes.

The recess has a first positioning inner stop 101 and a second positioning inner stop 102, respectively for clamping thicker and thinner pencils. This allows for cutting pencils of varying diameters without replacing the positioning fixture; the pencil can be rotated by simply securing the pencil, resulting in rapid cutting, improved cutting efficiency, and ease of use. The cut pencils are aesthetically pleasing and of reliable quality.

[0043] In some embodiments of the present application, a plurality of fixing holes 105 are distributed on the skirt of the base 11 along the axial direction of the base 11 , and the angles between any two adjacent fixing holes 105 are equal.

[0044] In this embodiment, the tool body 1 is mainly connected to the chain module through the body positioning stop 103. In order to improve the reliability of the connection, screws can also be passed through the fixing holes 105 to lock and connect the tool body 1 and the chain module.

[0045] In a second aspect, an embodiment of the present application further provides a multi-size positioning system, comprising a workpiece and a multi-size positioning tool as described in any embodiment of the first aspect;
