Description

Technical Field

[0001] The utility model relates to the field of tooling structure for processing a water injection port mounting seat of a rail train. Background Art

[0002] The high-speed EMU water injection port mounting seat is the main component for installing the water injection port. It is welded from a bent plate and a side plate, and then the mounting hole is machined on the bent plate. Due to the irregular shape of the component, both the front and back installation require processing, and there is no specific processing tooling for clamping. The clamping is difficult and time-consuming, which wastes man-hours and resources and has low production efficiency. Designing a suitable processing tooling can greatly improve production efficiency. Utility Model Content

[0003] The purpose of the utility model is to improve the product quality of the water injection port mounting seat and the production efficiency of the machining process, so as to ensure the use requirements of the subsequent process.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a standard EMU water injection port mounting seat processing tooling structure, including a base, two support plates, two screws, a normal mounting seat, a support top plate, a stud and a reverse mounting seat, the base and the machine tool worktable are clamped by a clamp, the normal mounting seat and the reverse mounting seat are fixed on the base, the normal mounting seat can be used to place the processed workpiece in a normal manner, and the reverse mounting seat can be used to place the processed workpiece in a reverse manner, the support top plate is fixed on the base and is located at the front end of the normal mounting seat, and a gap is left between the support top plate and the normal mounting seat , used to place the workpiece, a threaded hole is provided on the upper part of the support top plate, and the workpiece can be tightened on the normal mounting seat by fasteners, the two screws are respectively fixed on the base and located on both sides of the normal mounting seat, the two support plates are respectively fixed on the base and located on both sides of the screw, the longitudinal height of the support plate is lower than the longitudinal height of the screw, the support plate and the screw press the workpiece on the normal mounting seat through a clamp and a nut, and a stud is provided on the reverse mounting seat, and when the workpiece is reversed, the workpiece is pressed on the reverse mounting seat through a clamp and a nut.

[0005] Furthermore, the fastener includes a screw.

[0006] The advantages of this structure are: (1) integrated device, the water injection port is installed to facilitate the operation of putting on and taking off the tire;

[0007] (2) No need for secondary leveling and alignment when switching between forward and reverse installation;

[0008] (3) Reduce the workload of front-line operators and save man-hours.

[0009] (4) The cost of tooling production is low, and multiple tooling can be used for assembly line operations to improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The utility model comprises a base 1, two support plates 2, two screw rods 3, a normal mounting seat 4, a support top plate 5, a stud 6 and a reverse mounting seat 7. The base 1 is clamped with a machine tool worktable by a clamp, the normal mounting seat 4 and the reverse mounting seat 7 are fixed on the base 1, the normal mounting seat 4 can be used to place a workpiece normal, and the reverse mounting seat 7 can be used to place a workpiece reversely, the support top plate 5 is fixed on the base 1 and is located at the front end of the normal mounting seat 4, a gap is left between the support top plate 5 and the normal mounting seat 4 for placing the workpiece, and the support top plate 5 is used to place the workpiece. A threaded hole is provided on the upper part of the plate 5, and the workpiece can be tightened on the normal mounting seat 4 by fasteners. The two screws 3 are respectively fixed on the base 1 on both sides of the normal mounting seat 4. The two support plates 2 are respectively fixed on the base 1 on both sides of the screw 3. The longitudinal height of the support plate 2 is lower than the longitudinal height of the screw 3. The support plate 2 and the screw 3 press the workpiece on the normal mounting seat 4 through clamps and nuts. The reverse mounting seat 7 is provided with studs 6. When the workpiece is reversed, the workpiece is pressed on the reverse mounting seat 7 through clamps and nuts.

[0015] During installation, the processing tooling structure is clamped on the machine tool workbench and fixed, and then the welded water injection port mounting seat is placed upright on the tooling structure, the water injection port mounting seat is fixed with a clamp, and the upright processing holes and chamfers are started.

[0016] After completing the forward-mounted processing, place it in the reverse-mounted position and continue processing the four surrounding sides to finally complete the processing of the entire water inlet mounting seat.
