Description

Technical Field

[0001] This utility model relates to the technical field of horizontal boring machine multi-station indexing plates, specifically a horizontal boring machine multi-station indexing plate with auxiliary structures. Background Technology

[0002] In the field of machining, horizontal boring machines, as high-precision hole and plane machining equipment, often need to be equipped with multi-station indexing plates to realize multi-face and multi-process continuous machining of workpieces. The multi-station indexing plate drives the tooling fixture to switch between different machining stations through the rotation indexing mechanism, which greatly improves the efficiency of batch production. It is widely used in the machining of box-type and shell-type parts. Currently, the multi-station indexing plates equipped with horizontal boring machines mostly rely on manual or simple mechanical structures to control the rotation angle. After the tooling fixture is fixed to the indexing plate table by bolts, the angle positioning is achieved by means of the scale lines or positioning pins on the indexing plate.

[0003] However, existing multi-station indexing tables have key drawbacks: after the workpiece is clamped by the fixture, the indexing table lacks a precise angle detection and feedback auxiliary structure when rotating. Operators can only observe the scale with their naked eyes or rely on experience to judge the machining angle, making it difficult to accurately control the accuracy of the rotation indexing. This can easily lead to problems such as workpiece machining station offset and hole system position deviation. At the same time, although some indexing tables are equipped with basic angle indicators, the indicator signals are easily affected by vibration and oil contamination in high-speed rotation or complex machining environments, making it impossible to transmit angle information in real time and accurately. Furthermore, they cannot be linked with the boring machine machining system to achieve automatic compensation. With the increasing requirements for precision and automation in machining, traditional multi-station indexing tables that lack reliable angle auxiliary positioning can no longer meet the needs of high-precision machining. Therefore, we propose a horizontal boring machine multi-station indexing table with an auxiliary structure. Utility Model Content

Rotary reading rod 8: Rotary connection to the outside of the rotating support shaft 21, one end is connected to the reading point rod 10 and the bottom surface is connected to the rotating wheel support platform 19, used to drive the reading point rod 10 to align with the scale; Auxiliary rotary wheel 9: Rotatably connected to the outside of the rotary wheel support shaft 20, with its bottom surface slidingly contacting the top surface of the workstation indexing plate 2, reducing the frictional resistance when the rotating reading rod 8 rotates; Reading point rod 10: Fixed to one end of the rotating reading rod 8, with the end aligned with the scale groove of the workstation scale plate 2, used to accurately indicate the reading position; Rotation support hole 11: It is opened on the top surface of the indexing plate support frame 1, and the hole diameter is adapted to the installation adjustment table 7 to provide support and guidance for its rotation; Active detection gear 12: Fixed to the outer side of the bottom of the mounting adjustment table 7, meshing with the driven detection gear 18, rotating synchronously with the mounting adjustment table 7 and transmitting power; Coupling 13: Connected between the bottom surface of the gear support shaft 16 and the detection output shaft of the encoder 14, it is used to transmit rotational motion and ensure the stability of power transmission; Encoder 14: Fixed inside the anti-fouling cover 3, it receives the rotation signal of the gear support shaft 16 through the coupling 13 and converts the mechanical rotation into an electrical signal; Limiting boss 15: Fixed to the outer side of the bottom of the gear support shaft 16, with its top surface in contact with the driven detection gear 18, used to limit the axial position of the driven detection gear 18; Gear support shaft 16: Rotatably connected to the bottom surface of indexing plate support frame 1, with driven detection gear 18 fixed on the outside and bottom coupling 13 connected to the outside, providing rotational support for the driven detection gear; Gear support frame 17: fixed to the bottom surface of indexing plate support frame 1, with the active detection gear 12 and the driven detection gear 18 attached to the inner top surface, used to assist in supporting the gears and ensure stable meshing; Driven detection gear 18: Fixed to the outside of gear support shaft 16, meshing with active detection gear 12, transmitting the rotation of mounting adjustment table 7 to gear support shaft 16; Rotary wheel support platform 19: fixed to the bottom surface of the rotating reading rod 8, with a rotary wheel support shaft 20 fixed on the inner side, used to support the auxiliary rotary wheel 9; Rotary wheel support shaft 20: fixed to the inner side of the rotary wheel support platform 19, and rotatably connected to the auxiliary rotary wheel 9 on the outer side, providing a rotation shaft for the auxiliary rotary wheel; Rotary support shaft 21: fixed inside the mounting slot of the mounting adjustment table 7, and rotatably connected to the rotating reading rod 8 on the outside, providing a fulcrum for the rotating reading rod; Working Principle: When this utility model is used, the indexing plate support frame 1 provides stable support for the overall structure. The station indexing plate 2, fixed on its top surface, serves as an angle reference component. The large and small scale grooves 5 and 6, evenly distributed in annular pattern on the top surface, constitute the scale reference for angle reading. The mounting adjustment table 7 achieves bidirectional rotational connection with the inner side of the station indexing plate 2 through the rotation support hole 11 of the indexing plate support frame 1. After the tooling fixture is fixed on the top surface of the mounting adjustment table 7, it can be driven by external force to rotate around the axis of the rotation support hole 11, thereby driving the workpiece to switch processing positions and providing a rotational basis for subsequent angle reading and inspection. During angle reading and detection, the angle reading component moves synchronously with the mounting adjustment table 7, providing precise assistance for manual reading: the rotating support shaft 21 in the mounting groove on the side of the mounting adjustment table 7 provides a rotation fulcrum for the rotating reading rod 8. When the mounting adjustment table 7 rotates, the auxiliary rotating wheel 9 at the bottom of the rotating reading rod 8 slides on the top surface of the workstation indexing plate 2 through the support of the rotating wheel support shaft 20 and the rotating wheel support table 19, reducing rotational friction; the reading point rod 10 at one end of the rotating reading rod 8 is always aligned with the scale groove of the workstation indexing plate 2, and the operator can quickly read the large scale groove 5 (coarse angle) and the small scale groove 6 (fine angle) pointed to by the reading point rod 10. The system quickly reads the current rotation angle, avoiding errors caused by direct visual observation of the scale and improving the efficiency and accuracy of manual reading. Simultaneously, the active detection gear 12 on the outer side of the bottom of the adjustment platform 7 rotates synchronously with it. Through gear meshing, it drives the driven detection gear 18 within the gear support frame 17 on the bottom surface of the indexing plate support frame 1 to rotate. The gear support shaft 16 provides rotational support for the driven detection gear 18, and the bottom limiting boss 15 prevents axial displacement of the driven detection gear 18, ensuring transmission stability. The rotational motion of the driven detection gear 18 is transmitted to the coupling 13 via the gear support shaft 16, and the coupling 13 transmits power to the anti-fouling cover 3. The encoder 14 inside converts the mechanical rotation angle into an electrical signal. The electrical signal of the encoder 14 is transmitted to the encoder angle display screen 4 on the top surface of the indexing plate support frame 1, which displays the accurate rotation angle data in real time. The operator can intuitively check whether the angle meets the processing requirements through the display screen. At the same time, the signal of the encoder 14 can be connected to the boring machine control system to provide data support for automatic compensation of angle deviation during the processing, further improving the processing accuracy. In addition, the anti-fouling cover 3 can effectively isolate oil and dust in the processing environment, prevent the encoder 14 from being contaminated and affecting the detection accuracy, and ensure the long-term stable operation of the angle detection component.
