Description

Technical Field

[0001] The utility model relates to the technical field of pin pulling tools, and in particular to a positioning taper pin removing device. Background Art

[0002] Pin extraction is often necessary in mechanical and mold processing and manufacturing. Because pins of varying diameters often need to be installed in different locations on machinery and molds, corresponding pin extraction tools are required, and workers frequently need to switch between them. Ordinary conical pins used for positioning lack internal and external threads, making them difficult to remove and requiring a punch to be hammered out. Traditionally, a handheld punch is used to strike the conical pin. This method lacks positioning aids, presents safety risks, and introduces inconvenience, reducing work efficiency and increasing operating time. Utility Model Content

[0003] In order to make up for the deficiencies of the prior art, the utility model provides a positioning taper pin removing device.

[0004] The utility model is realized by the following technical solutions: a positioning cone pin removal device, comprising a conical punch, a hammer and a limiting sleeve, wherein the upper inner diameter of the limiting sleeve matches the outer diameter of the conical punch, the lower inner diameter of the limiting sleeve gradually increases from top to bottom, and a hammer sleeve mechanism is installed on the top of the conical punch;

[0005] The hammer sleeve mechanism is divided into two parts, including an upper hammer pad and a lower mounting sleeve. The bottom of the mounting sleeve is provided with a mounting hole for mounting on the top of the conical punch, and the inside of the mounting hole is stepped and gradually reduced.

[0006] As a preferred solution, the hammer sleeve mechanism is made of silicone material.

[0007] As a preferred solution, the hammer pad has a disc shape.

[0008] Furthermore, the outer shape of the mounting sleeve is cylindrical.

[0009] Furthermore, the outer diameter of the hammer pad is larger than the outer diameter of the mounting sleeve.

[0010] Due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art: through the technical solution of the present invention, the limiting sleeve is used for simple and effective positioning, and at the same time it plays a role in limiting the movement of the conical punch, preventing the conical punch from being impacted and deviating from its position during operation; in addition, the hammering sleeve mechanism can prevent the operator's hand from being accidentally injured during hammering to a certain extent, avoiding certain safety hazards, and different conical punches can be replaced through the stepped mounting holes inside to remove positioning cone pins of different sizes.

[0021] like Figure 1 As shown, the utility model proposes a positioning cone pin removal device, including a cone punch 1, a hammer 2 and a limiting sleeve 3 as shown in FIG. Figure 2 As shown, the upper inner diameter of the limit sleeve 3 matches the outer diameter of the conical punch 1, and the lower inner diameter of the limit sleeve 3 gradually increases from top to bottom. The limit sleeve 3 can have multiple different sizes to correspond to conical punches 1 of different sizes. A hammer sleeve mechanism is installed on the top of the conical punch 1; the material of the hammer sleeve mechanism is silicone material.

[0022] like Figure 3As shown, the hammer sleeve mechanism is divided into two parts, including an upper hammer pad 4 and a lower mounting sleeve 5. The bottom of the mounting sleeve 5 is provided with a mounting hole 6 for mounting on the top of the conical punch 1. The interior of the mounting hole 6 is stepped and gradually reduced to match conical punches 1 of different sizes. The outer shape of the hammer pad 4 is disc-shaped, and the outer shape of the mounting sleeve 5 is cylindrical.
