Description

Technical Field

[0001] This invention relates to a processing equipment and method for the armature, a key component of a signal relay, and particularly to a processing equipment and method for the top recess hole of the armature in a railway signal relay. Background Technology

[0002] Various types of railway signal relays are widely used in railway and urban rail transit signal control systems. These products consist of two main parts: a magnetic circuit assembly and a contact assembly. The armature is the core component of the relay, forming the electromagnetic system of the relay along with the coil, a fixed iron core, and a yoke. The armature is L-shaped and is formed from straight electrical pure iron bars through processes such as blanking, punching, deformation, shaping, milling, bench drilling, and surface treatment. Currently, the armature top recess machining method involves drilling a jig for single-sided positioning, manually pressing the positioning surface, and bench drilling the recess. Different tooling needs to be changed each time different armature models are machined. This machining method is cumbersome, resulting in large variations in recess dimensions, low production efficiency, and poor consistency.

[0003] With the rapid development of railways and urban rail transit, the demand for railway signal relays has increased significantly, and there are also higher requirements for the reliability and stability of the products, necessitating improvements to current processing methods. Summary of the Invention

[0004] The purpose of this invention is to provide a processing equipment and method for armature top socket holes of railway signal relays. It realizes self-alignment and positioning of armature top socket machining center, automatic loading and unloading, double-sided positioning and clamping of drill jig, pneumatic pressing of positioning surface, and completes all processes (pointing and drilling) in one clamping and one processing. The same tooling can process all types of armature top socket processes, with high processing accuracy and improved processing technology capability of parts machining center fitter group.

[0005] The technical solution of this invention is: to provide a processing equipment and method for the armature top socket of a railway signal relay, characterized in that: it includes: a control and display unit, a feeding mechanism, a drilling mechanism, a loading mechanism, a unloading mechanism, an armature clamping mechanism, an external sealing waterproof cover, and a rectangular base with a leveling foot at each of the four corners; a feeding mechanism is located at one end of the rectangular base, and a drilling mechanism is located directly above the rectangular base, the drilling mechanism including: a base and a side base, the side base being located at the upper end of the base, and the lower end of the base being leveled by the leveling feet; the lower end of the drill bit of the drilling mechanism has a loading mechanism, an unloading mechanism, and an armature clamping mechanism for processing the armature, and the drilling mechanism, loading mechanism, unloading mechanism, and armature clamping mechanism are sealed by the external sealing waterproof cover; during operation, the semi-finished armature is manually placed on the loading mechanism. On the material conveyor line, the semi-finished armature is conveyed to the side of the limit block by the feeding conveyor line. The feeding telescopic cylinder extends, and the high vacuum adsorption head adsorbs the armature onto the high vacuum adsorption head. The feeding lifting cylinder moves upward, and the lateral movement cylinder moves the armature to the armature profile block of the armature clamping mechanism. The armature clamping mechanism automatically centers and clamps the armature through the centering pre-clamping mechanism, and the armature surface pressing mechanism presses and fixes the armature reference surface. The servo feed motor moves the drill bit down to perform top hole and drilling processing. After processing, the lateral movement cylinder moves, the unloading telescopic cylinder extends, and the high vacuum adsorption head adsorbs the armature onto the high vacuum adsorption head. The lateral movement cylinder moves the armature to the top of the unloading track, the rotation cylinder rotates the armature, and the unloading lifting cylinder lowers to place the armature on the unloading track, and the processed armature is transported out.

[0006] The control and display unit can set the height of the drill bit descent and the processing time of the drill bit top socket.

[0007] The aforementioned top socket and drilling specifically include the following steps:

[0008] (1) Preparation process: Arrange the semi-finished armatures to be processed neatly on the feeding line. Use sensors at the bottom of the feeding line to detect the semi-finished armatures placed on the feeding line. The reference surface of the armature faces forward. Connect the power and air supply of the special equipment for the armature top socket.

[0009] (2) Feeding: When feeding, the feeding telescopic cylinder extends, the high vacuum adsorption head adsorbs the armature onto the high vacuum adsorption head, the feeding lifting cylinder moves upward, and the transverse cylinder moves the armature to the drilling mechanism.

[0010] (3) Processing: The armature clamping mechanism automatically centers and clamps, and the armature pressing surface mechanism presses and fixes the armature reference surface to ensure that the product reference surface is fixed and to eliminate the deviation caused by the product angle. The servo feed motor runs the drill bit down, and after it is lowered to the adjustment position, the rotating power motor runs to process the armature top socket, accurately control the drilling depth, and after processing, use the high-pressure air pipe to clean the iron filings and water stains to ensure that the product placement surface is clean. The socket size is (2.3±0.05)×90°, and the angle between the center of the socket and the reference surface is 135°±5'.

[0011] (4) Unloading: During unloading, the unloading telescopic cylinder extends, the high vacuum adsorption head adsorbs the armature onto the high vacuum adsorption head, the transverse cylinder moves the armature above the unloading track, the rotary cylinder drives the armature to rotate, the unloading lifting cylinder descends to place the armature on the unloading track, the unloading track runs and transports the armature out.

[0012] The advantages of this invention are that it improves the machining accuracy of the armature part's top socket, enhances the consistency and symmetry requirements of the armature top socket machining, and improves the overall machine performance. It transforms the existing bench drill into an integrated machine with self-aligning center positioning, achieving double-sided positioning and clamping of the drill bit, and pneumatic clamping of the positioning surface. All machining processes (point socketing, drilling) are completed in a single setup and machining operation. The same tooling can process all types of armature top sockets, and the dedicated machine is suitable for machining all armature top socket holes.

The base consists of a base 8 and a side base 28, with the side base 28 located at the top of the base 8. The bottom of the base 8 is leveled using leveling feet 9. The drilling mechanism 3 has a drill bit 30 at its lower end, which includes a feeding mechanism 4, a discharging mechanism 5, and an armature clamping mechanism 6 for processing the armature 14. These components are sealed by an external waterproof cover 7. During operation, the semi-finished armature 12 is manually placed on the feeding line 11, and the semi-finished armature 12 is fed through the feeding line. The assembly line 11 conveys the semi-finished armature 12 to the side of the limiting block 13. The feeding telescopic cylinder 22 extends, and the high vacuum adsorption head 25 adsorbs the semi-finished armature 12 onto the high vacuum adsorption head 25. The feeding lifting cylinder 19 moves upward, and the lateral movement cylinder 24 moves the semi-finished armature 12 onto the armature contour block 16 of the armature clamping mechanism 6.

After it reaches the adjusted position, the rotation power motor 26 runs to perform the top socket machining of the armature 14. Then, the precise drilling and drilling depth are controlled. After the machining is completed, the high-pressure air pipe 29 on one side of the drill bit 30 is used to clean the iron filings and water stains to ensure that the surface on which the armature 14 is placed is clean.
