AI Technical Summary
During the splicing process of existing curved tracks, the unidirectional setting of the positioning pins causes the connection accuracy of components to be affected by offset, thus affecting the connection stability and accuracy.
The first and second locating pins are arranged perpendicularly to each other, and the first flange and the second flange are fixed together by screws and nuts to ensure the stability and accuracy of the rail connection.
A stable connection of the curved track was achieved, preventing the track from shifting radially and improving the tightness and reliability of the connection.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of track equipment technology, and in particular to an arc-shaped track connection structure. Background Technology
[0002] In various manufacturing enterprises, to achieve rapid transfer of raw materials between different production workshops, corresponding material transfer equipment is often configured. This equipment typically employs rail-guided systems to accurately control the material transfer position. Due to limited space in some production workshops, some rails must be manufactured in an arc shape. If a long rail length is required, multiple sections of unit rails must be spliced together during rail fabrication. For example, patent document CN214161962U discloses an arc-shaped rail positioning device for welding stainless steel tanks, belonging to the field of industrial equipment manufacturing. Its characteristic is that it comprises two symmetrical sets, each consisting of 2-4 arc-shaped rails. The arc-shaped track is composed of movable track segments, with stainless steel connecting plates on both sides of the bottom of each movable track segment; and connecting shafts or connecting ears are set on two adjacent movable track segments. Fastening bolts are set on the connecting shafts, and positioning holes are set on the movable track segments. A positioning connecting rod is set between two mutually symmetrical movable track segments. The positioning connecting rod is connected to the positioning holes set on the movable track segments, and an adjustment device is set on the positioning connecting rod. By setting positioning holes on the two track segments, the welding accuracy is improved. However, in the prior art, the positioning pins in the positioning device are mostly set in a single direction. When the two components are offset along the axial direction of the positioning pin, the connection accuracy between the two components will also be affected. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides an arc-shaped track connection structure.
[0004] This utility model is achieved through the following technical solution.
[0005] This utility model provides an arc-shaped track connection structure, including a first flange, a second flange, a first positioning pin, and a second positioning pin. The first flange is fixedly connected to a first track, and the second flange is fixedly connected to a second track. The first positioning pin passes through the first flange and the second flange in sequence, and the second positioning pin is clamped between the first flange and the second flange. The second positioning pin also passes through the first positioning pin.
[0006] The axial direction of the first locating pin intersects perpendicularly with the axial direction of the second locating pin.
[0007] The first locating pin is a tapered pin.
[0008] Using the interface between the first flange and the second flange as a mirror plane, the second locating pins are symmetrically distributed on the left and right sides of the mirror plane.
[0009] The second locating pin is a cylindrical pin.
[0010] The first flange and the first track are manufactured as a single piece.
[0011] The second flange and the second track are manufactured as a single piece.
[0012] The arc-shaped track connection structure also includes a screw and a nut, one end of the screw is screwed to the nut, and the first flange and the second flange are clamped between the other end of the screw and the nut.
[0013] The beneficial effects of this utility model are as follows: by adopting the technical solution of this utility model, a first positioning pin and a second positioning pin are set so that the first track and the second track cannot deviate along the radial direction of the first positioning pin and the radial direction of the second positioning pin, thus ensuring the connection accuracy between the first track and the second track. The second positioning pin also penetrates the first positioning pin, connecting the two positioning components into one, making the connection between the first track and the second track tighter, more stable and reliable.

[0018] The technical solution of this utility model is further described below, but the scope of protection is not limited thereto.
[0019] like Figures 1 to 3 As shown, this utility model provides an arc-shaped track connection structure, including a first flange 1, a second flange 2, a first positioning pin 3 and a second positioning pin 4. The first flange 1 is fixedly connected to the first track 7, and the second flange 2 is fixedly connected to the second track 8. The first positioning pin 3 passes through the first flange 1 and the second flange 2 in sequence, and the second positioning pin 4 is clamped between the first flange 1 and the second flange 2. The second positioning pin 4 also passes through the first positioning pin 3.
[0020] By adopting the technical solution of this utility model, a first positioning pin and a second positioning pin are set to prevent the first track and the second track from deviating along the radial direction of the first positioning pin and the second positioning pin, thus ensuring the connection accuracy between the first track and the second track. The second positioning pin also penetrates the first positioning pin, connecting the two positioning components into one, making the connection between the first track and the second track tighter, more stable and reliable.
[0021] Specifically, the axial direction of the first locating pin 3 intersects perpendicularly with the axial direction of the second locating pin 4. Preferably, the first locating pin 3 is a tapered pin. Taking the interface between the first flange 1 and the second flange 2 as a mirror plane, the second locating pins 4 are symmetrically distributed on the left and right sides of this mirror plane. The second locating pins 4 are cylindrical pins.
[0022] Furthermore, the first flange 1 and the first track 7 are integrally manufactured. The second flange 2 and the second track 8 are integrally manufactured. The arc-shaped track connection structure also includes a screw 5 and a nut 6. One end of the screw 5 is screwed to the nut 6, and the first flange 1 and the second flange 2 are clamped between the other end of the screw 5 and the nut 6. There are two sets of screws 5 and nuts 6, which are arranged on the upper and lower sides of the first locating pin 3 and the second locating pin 4, respectively.
