Description

positioning pin

technical field

The utility model relates to a positioning device, in particular to a positioning pin which utilizes an elastic component to cooperate with a sliding part so that the position can be changed after being fixed.

Background technique

Existing locating pins or bolts are mainly used to connect workpieces and components. The structure of locating pins is simple and easy to connect. There is usually a small hole at the bottom, and a steel wire is put on to bend the protruding two ends to achieve safety. effect. The defect of the positioning pin is that after the connection, if the steel wire is used to penetrate, the steel wire will easily fall off after a long time of use, causing the two connected parts to separate; if the bottom is smashed flat, it is not easy to separate, but if the workpiece needs to be removed, The positioning pin must be destroyed, causing inconvenience; more importantly, the small hole of the positioning pin is usually only set at one end, so the position of the positioning pin piercing through the two parts is shallow and deep, and there is no degree of freedom, which causes inconvenience in use sex. The advantage of the bolt is that the bottom is tightened with a nut, but the locking action with a tool is time-consuming, and when the thread is damaged, it is difficult to disassemble and assemble, and the cost is high.

In view of this, in order to improve this problem, it is necessary to provide a positioning pin that can be positioned quickly, improves the convenience of use, has low manufacturing cost, and has a simple structure and can prevent the workpiece from falling off. Based on the technology and experience accumulated in related industries, the positioning pin is provided with a through threaded hole, combined with an elastic component and a sliding part, and then locked with a fastener to make it easy to disassemble, thus effectively Protect the workpiece from falling off and damage to maintain the safety of users.

Utility model content

The main purpose of the utility model is to provide a positioning pin, which uses the locking process of a fastener to adjust the elastic resistance of an elastic component, so as to control the movement of a rolling element.

Another object of the present invention is to provide a positioning pin, which utilizes the cooperation of the positioning pin and the sliding part to form a sliding part that can move freely in the positioning pin, so as to select a mechanism for positioning freedom.

In order to achieve the above purpose, the utility model provides a positioning pin, comprising: a bolt body, which is provided with a through threaded hole; a rolling element, placed in the threaded hole of the bolt body; an elastic component, placed in the bolt body The threaded hole of the bolt body, and one end of which is against the rolling member; a fastener, which is threadedly engaged with the threaded hole of the bolt body, and one end of which is against the elastic component.

The threaded hole can be used for accommodating sliding parts, elastic components and fasteners. The bolt body also has a chute connected through the threaded hole, and can allow the rolling member to move in the chute to Change the positioning position, when the position needs to be changed, the fastener can be disassembled, and the pressing pressure of the elastic component on the sliding part can be relaxed, so that the sliding part can move left and right along the chute without destroying the bolt body. The purpose of changing the position is achieved, so that the construction is easier and the assembly cost is also reduced.

Wherein, the plug body is a cone with unequal circles.

Wherein, the threaded holes are tapered holes with unequal diameters.

The beneficial effects of the utility model:

The arrangement of the utility model can effectively prevent workpieces or parts from falling off, and has the effects of easy disassembly and assembly and reduced assembly cost.

detailed description

The following examples illustrate the utility model only, but are not intended to limit the protection scope of the utility model.

Relevant technical scheme and structural feature that the utility model uses for reaching the purpose, cooperate accompanying drawing again now, describe in detail as follows:

The utility model provides a positioning pin, which is used for workpieces and fixtures to be positioned (figure omitted), please refer to Figure 1 and Figure 2, which mainly includes: a bolt body 1, whose shape is a cone-shaped body with unequal circles, The cross-section is divided into perfect circles, and there are threaded holes 11 and 12 through the front and rear ends respectively (however, it is not necessary to set threaded holes at the front and rear ends, and threaded holes at different positions can be set according to construction requirements, and of course there is no limit The number of threaded holes) is a tapered hole with unequal diameters. The diameters of the threaded holes are not equal in the axial direction, so as to form a large opening and a small bottom. A rolling element 2 is provided for accommodating an elastic component. 3, so that a fastener 4 is locked and fixed on it. Since the threaded holes 11, 12 cooperate with the fastener 4 to be designed with equidistant threads, the overall tensile strength can be strengthened, and it has the effect of preventing falling off.

A rolling member 2, which is a circular sphere in this embodiment, is placed at the bottom of the threaded holes 11, 12, an elastic component 3 is installed in the threaded holes 11, 12, and one end of the elastic component 3 is against the rolling element. The other end of the fastener 2 is pressed against the fastening piece 4, and the elastic force of the elastic component 3 is used to push the rolling piece 2, so that the rolling piece 2 protrudes slightly outside the bolt body 1, thereby having a positioning function.

A fastener 4, the top surface is provided with grooves and a threaded part 41 that can be tightened and loosened by manpower or tools, and the fastener 4 can be locked and loosened by rotating clockwise or counterclockwise. The part 41 is suitable for the threaded holes 11, 12 to be designed as a male and female thread. When positioning and locking, the fastener 4 can be completely locked into the bolt body 1. The hidden design has more beautiful functions, in addition to preventing falling off. It also has the characteristics of quick disassembly and assembly.

Please refer to Figure 3 and Figure 4 at the same time, which are specific embodiments of the present utility model. When installing, first put the rolling element 2 into the threaded hole 11, and then insert the elastic component 3. The elastic The end of the component 3 is set in the shape of a circular arc chamfer, so that the diameter of the end part is smaller than or equal to the rolling element 2, and the other end is against the fastener 4. Through the thread locking effect of the fastener 4, it can be squeezed The elastic component 3 is squeezed and compressed, and the pressure will indirectly cause the rolling element 2 to protrude from the bolt body 1, and the protruding part contacts the work object to be fixed, so that it has a fixing effect. This achieves a positioning effect.

Please refer to Fig. 4 again, a chute 13 is provided in the bolt body 1, the chute 13 is parallel to the longitudinal axis of the bolt body 1, the chute 13 is connected to the threaded holes 11, 12, and can be used for the rolling element 2 The chute 13 moves to change the positioning position. During operation, loosen the fastener 4a with tools or manpower, relax the pressure of the elastic component 3a, and make the rolling member 2 reach the threaded hole along the chute 13 12, as mentioned above, lock the fastener 4b, squeeze and fix the elastic component 3b, so that the rolling element 2 protrudes outside the threaded hole 12, thereby changing the positioning position to achieve the purpose of convenient use.

The positioning pin provided by the utility model utilizes the design of the male and female threads of the bolt body 1 and the fastener 4 to improve the overall locking strength, and can also change the positioning position according to the demand. It has the characteristics of quick disassembly and assembly, and has great industrial applicability.
