[0015] Example 1 like Figure 1-5The fixture shown includes a positioning and assembly jig for a 90° turnout, comprising: a base frame 1, a fixture plate 2, and a turnout positioning and assembly mechanism 3. A flipping mechanism 11 is disposed above the base frame 1. The fixture plate 2 is positioned above the base frame 1 via the flipping mechanism 11. The turnout positioning and assembly mechanism 3 is disposed on the fixture plate 2 and includes: a turnout positioning block 31, a rotary clamping cylinder 32, and a push rod cylinder 33. The turnout positioning block 31 is fixedly disposed on the fixture plate 2 and is positioned according to the outer extension edge of the 90° turnout frame. A positioning groove is provided in the middle of the turnout positioning block 31. Hole 311 is used to engage with the outer extension edge of the turnout frame for positioning and fixing; several rotary clamping cylinders 32 are arranged on the tooling plate 2, and the rotary clamping cylinders 32 are arranged along the turnout track, on both sides of the straight track and on both sides of the 90° bent track, for positioning and clamping the turnout track; the push rod cylinder 33 is arranged on the outer side of the tooling plate 2, and there are two of them, one perpendicular to the side of the tooling plate 2, which is used to calibrate the straight track when pushed out, and the other is arranged at a 90° angle to the side of the flipping mechanism 11, which is used to calibrate the bent track when pushed out. The push rod cylinder 33 is a double-shaft double-rod cylinder. The turnout frame is installed and positioned on the turnout positioning block 31, and then the various parts are placed and installed. The turnout track is aligned by pushing the push rod cylinder 33, and then the track is fixed by pressing down and rotating the clamping cylinder 32. The flipping mechanism 11 flips the tooling plate 2, and then the self-tapping screws are driven in to fix the track. The installation is convenient and quick, and it can be quickly positioned and fixed without manual measurement and adjustment, avoiding assembly errors. Moreover, it adopts a dual-station design with two sets of turnout positioning and assembly mechanisms 3, which can simultaneously install 30° right turnouts and 30° left turnouts, improving assembly efficiency.
[0016] like Figure 1 The tooling fixture shown is for positioning and assembling 90° turnouts. The base frame 1 is provided with adjustable legs to control the height adjustment and maintain the balance of the tooling.
[0017] like Figure 3The illustration shows a fixture for assembling a 90° turnout. The flipping mechanism 11 includes a fixed shaft seat 111, a hand-cranked reducer 112, and a fixture plate positioning pin 113. The fixed shaft seat 111 is located on the upper side of the base frame 1, with a rotating shaft in the middle connecting to the fixture plate 2. The hand-cranked reducer 112 is mounted on an external mounting plate on one side of the upper base frame 1 and connected to the fixed shaft seat 111. The hand-cranked reducer 112 controls the flipping of the fixture plate 2. The fixture plate positioning pin 113 is located on the base frame 1 to fix the fixture plate 2. During assembly, the fixture plate positioning pin 113 fixes the main fixture plate 2. After assembly, when the track needs to be fixed, the fixture plate positioning pin 113 releases the fixation of the fixture plate 2, and the fixture plate 2 is flipped by rotating the hand-cranked reducer 112. Since the parts are in a fixed state at this time, the flipping will not cause movement. The fixation is then secured from the bottom of the work plate with self-tapping screws. The operation is convenient, quick, and saves time and effort.
[0018] In this embodiment, the tooling plate positioning pin 113 is set on the base frame 1 on both sides of the fixed rotating shaft seat 111, and the tooling plate 2 is provided with corresponding pin holes 114. When fixing the tooling plate 2, the tooling plate positioning pin 113 is inserted into the pin holes 114, and the tooling plate 2 is fixed and locked at four points.
[0019] Example 2 Based on Example 1, in this example, as... Figure 4 The diagram shows a fixture for assembling a 90° turnout. The fixture plate 2 has several self-tapping screw mounting holes 21 and multiple installation observation holes 22. The self-tapping screw mounting holes 21 correspond to the track fixing positions. After the fixture plate 2 is flipped, self-tapping screws can be directly driven into the self-tapping screw mounting holes 21 to complete the track fixing.
[0020] In this embodiment, the turnout positioning assembly mechanism 3 further includes a track support block 34, a track spacing block 35, and a cylinder rotation shaft fixing block 36. Several track support blocks 34 are arranged on the tooling plate 2 at the turnout track installation position to support the turnout track. The track spacing block 35 is arranged on the tooling plate 2 to limit the straight rail of the turnout track. The cylinder rotation shaft fixing block 36 is arranged on the tooling plate 2 at the turnout track pivot position and presses against the turnout track pivot during assembly for positioning and fixing.
[0021] like Figure 1The diagram illustrates a fixture for assembling a 90° turnout. The fixture plate 2 is equipped with a manual valve 4, which controls a push rod cylinder 33 to extend and calibrate the turnout track to the correct position. After assembly, the operator controls the push rod cylinder 33 via several manual valves 4, each corresponding to a push rod cylinder 33, allowing for individual control and calibration of the track to the correct position. This enables rapid positioning and fixation without manual measurement or adjustment, avoiding assembly errors and improving assembly efficiency.
[0022] It should be noted that the above description is merely a technical solution of the utility model and not a limitation. Although the present utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of the utility model without departing from the scope of the present utility model, and all such modifications and substitutions should be covered within the scope of the claims of the present utility model.
