AI Technical Summary
Existing drilling equipment positioning fixtures cannot effectively position curved plates, causing the curved plates to easily slip during processing and failing to meet accuracy requirements.
An arc plate positioning fixture was designed, comprising a platform, a first stop bar, and a drive mechanism. The arc plate is kept stable during drilling by the cooperation of the arc wall of the platform and the stop bar. The drive mechanism is used to make each row of pre-drilled holes on the arc plate reach the highest point in sequence, thereby achieving precise positioning.
It achieves effective positioning of the curved plate during the drilling process, avoids slippage, and meets the accuracy requirements for drilling on the curved plate.

Abstract
Claims
1. An arc plate positioning tool characterized by, include: The positioning mechanism includes a platform and a first stop bar. The platform is a columnar structure with the same curvature of its arc-shaped wall as that of the arc-shaped plate. Its axis extends horizontally. The arc-shaped wall of the platform is used to rotatably place the arc-shaped plate. The first stop bar is an arc-shaped structure and is rotatably sleeved on the platform. The two ends of the first stop bar are respectively used to abut against the two circumferential side walls of the arc-shaped plate. A drive mechanism, which is connected to the first stop bar, is used to drive the first stop bar to reciprocate so that each row of pre-drilled holes on the arc plate reaches the highest point in sequence.
2. The arc plate positioning tooling of claim 1, wherein, The platform has a positioning channel on its arc-shaped wall, which is used to place the arc-shaped plate and allow the arc-shaped plate to rotate around the central axis of the platform.
3. The arc-shaped plate positioning fixture according to claim 2, characterized in that, A row of clearance holes is provided at the highest point of the platform. Each clearance hole is arranged at intervals along the axial direction of the platform and is located within the positioning channel. Each clearance hole corresponds one-to-one with each pre-drilled hole in each row of pre-drilled holes on the arc plate.
4. The arc plate positioning tooling of claim 2, wherein, The positioning mechanism further includes two second stops, both of which are arc-shaped and are respectively arranged on both sides of the first stop. Both second stops can be detachably and fixedly sleeved on the platform, and the positioning channel is formed between the two second stops. The two second stops are respectively used to abut against the two side walls of the arc plate in the axial direction.
5. The arc-shaped plate positioning fixture according to claim 4, characterized in that, The positioning mechanism also includes multiple insertion shafts. Two rows of insertion holes are provided on the platform. Each insertion hole in the two rows of insertion holes is arranged at intervals along the circumference of the platform. Multiple through holes are provided on the two second baffles in the circumference. Each through hole corresponds to each insertion hole. Each insertion shaft is inserted into each through hole and insertion hole.
6. The arc plate positioning tooling of claim 2, wherein, The platform has a slide rail on its arc-shaped wall. The two ends of the slide rail are respectively connected to the two ends of the positioning channel. The slide rail is used to place the first stop bar and allow the first stop bar to rotate around the central axis of the platform.
7. The arc plate positioning tooling of claim 6, wherein, The positioning mechanism further includes two third stops, both of which are arc-shaped and are positioned opposite each other on both sides of the first stop. Both third stops can be detachably and fixedly sleeved on the platform, forming the slide between them. The two third stops are respectively used to abut against the two side walls of the first stop.
8. The arc plate positioning tooling of claim 1, wherein, The driving mechanism includes a gear and a first rotational driving component. The first stop bar is a rack structure. The gear meshes with the teeth on the first stop bar. The output end of the first rotational driving component is coaxially and fixedly connected to the gear to drive the gear to rotate.
9. The arc plate positioning tooling of claim 8, wherein, It also includes a base, the platform is detachably fixed to the base, and the first rotation drive is detachably fixed to the base.
10. A drilling apparatus, characterized by The invention includes an arc-shaped plate positioning fixture and drilling mechanism as described in any one of claims 1-9. The drilling mechanism includes a drill bit, a second rotation drive, a telescopic drive, and a moving assembly. The drill bit is vertically arranged and corresponds to the highest point of the platform. The output end of the second rotation drive is coaxially and fixedly connected to the upper end of the drill bit to drive the drill bit to rotate. The output end of the telescopic drive is fixedly connected to the second rotation drive to drive the second rotation drive to move up and down. The moving assembly is connected to the telescopic drive to drive the telescopic drive to move along the axial direction of the platform in a horizontal plane.
