Description

Technical Field

[0001] The utility model relates to the technical field of spacer irons, in particular to a tooling for processing spacer irons. Background Technique

[0002] The use of turnout spacer irons is extremely common, and they can be found in almost every railway transportation system. By connecting and supporting turnout plates and sleepers, the turnout can be switched normally, ensuring that trains can switch smoothly and safely between different tracks. In order to ensure the smooth switching of the turnout, it must have precise dimensions and shapes, and its surface will be processed. During the processing, a tooling is used to fix the spacer iron. The existing tooling is generally clamped and fixed by a bench vice, which has good versatility and low usage cost. However, when processing trapezoidal spacer irons, it is necessary to ensure the horizontality of its upper surface, but the bench vice lacks a leveling function. Usually, pads are used below to ensure the leveling of the spacer iron. The leveling operation is cumbersome and not easy to adjust, thus affecting the convenience of using the spacer iron.

A dial 12 is provided at the left end of the front side of the spacer block 3. A pointer 13 is provided on the front side of the support shaft 2. The pointer 13 is cooperatively arranged with the dial 12. The spacer block 3 drives the second slide block 8 and the dial 12 to rotate synchronously. The second slide block 8 drives the spacer iron to rotate synchronously through the clamping plate 9. At the same time, the rotation angle of the spacer block 3 is determined according to the relative position between the pointer 13 and the dial 12. Symmetrically distributed second slide blocks 8 are provided on the upper surface of the spacer block 3. The upper ends of the second slide blocks 8 are all slidably connected with symmetrically distributed clamping plates 9. The middle parts of the second slide blocks 8 are all rotatably connected with bidirectional lead screws 10 through bearings. The clamping plates 9 are all threadedly connected to the vertically corresponding bidirectional lead screws 10. The front ends of the bidirectional lead screws 10 are all slidably connected with handles 11. Place the spacer iron on the upper surfaces of the two second slide blocks 8 and make the surfaces fit. Then rotate the bidirectional lead screw 10 through the handle 11. The bidirectional lead screw 10 drives the clamping plate 9 to move towards the center along the second slide block 8. Thus, the two vertically corresponding clamping plates 9 clamp the spacer iron centeringly. The four clamping plates 9 can clamp the two ends of the spacer iron. When the upper and lower planes of the spacer iron are trapezoidal and not parallel, place the small head on the right side;

[0023] Adjusting assembly 4: It includes slide rail 141, sliding seat 42, H-shaped connecting rod 43 and connecting shaft 44.

H-shaped connecting rod 43 is connected to the right end of spacer iron seat 3 through connecting shaft 44. H-shaped connecting rod 43 is inclined upward from left to right. Furthermore, H-shaped connecting rod 43 will push spacer iron seat 3 to rotate around support shaft 2 through connecting shaft 44. A hexagonal column 5 is provided at the right end of lead screw 45. After clamping, use a wrench to hold hexagonal column 5 and rotate lead screw 45. A trapezoidal block 7 is slidably connected to the right end inside sliding seat 42.

The rear end of T-shaped bolt 6 is arranged in cooperation with trapezoidal block 7. After leveling, tighten T-shaped bolt 6. T-shaped bolt 6 drives trapezoidal block 7 to move backward. Trapezoidal block 7 presses slide rail 141 backward to lock sliding seat 42, ensuring the locking of the angle of spacer iron seat 3.

[0024] The working principle of a tooling for spacer iron processing provided by the present utility model is as follows: During use, install the bottom plate 1 on the working platform of the machine tool. Place the spacer iron on the upper surfaces of the two sliding seats 8. Make the surfaces fit. Then rotate the bidirectional lead screw 10 through the handle 11. Bidirectional lead screw 10 drives the clamping plates 9 to move towards the center along sliding seats 8. Furthermore, the two longitudinally corresponding clamping plates 9 will center and clamp the spacer iron. The four clamping plates 9 can clamp both ends of the spacer iron. When the upper and lower planes of the trapezoidal spacer iron are not parallel, place the small end on the right side. After clamping, use a wrench to hold hexagonal column 5 and rotate lead screw 45. Lead screw 45 drives sliding seat 42 to slide rightward along slide rail 141. Sliding seat 42 drives the left end of H-shaped connecting rod 43 to move rightward. H-shaped connecting rod 43 is connected to the right end of spacer iron seat 3 through connecting shaft 44. Furthermore, H-shaped connecting rod 43 will push spacer iron seat 3 to rotate around support shaft 2 through connecting shaft 44. Spacer iron seat 3 drives sliding seats 8 and the scale disk 12 to rotate synchronously. Sliding seats 8 drive the spacer iron to rotate synchronously through clamping plates 9. At the same time, determine the rotation angle of spacer iron seat 3 according to the relative position of the pointer 13 and the scale disk 12. Furthermore, level the upper surface of the spacer iron. After leveling, tighten T-shaped bolt 6. T-shaped bolt 6 drives trapezoidal block 7 to move backward. Trapezoidal block 7 presses slide rail 141 backward to lock sliding seat 42, ensuring the locking of the angle of spacer iron seat 3 and facilitating the processing of the upper surface of the spacer iron.
