Description

Technical Field

[0001] This utility model relates to a circular arc-shaped gear pump body tooling, and more particularly to a multi-station rotary tooling for a circular arc-shaped gear pump body. Background Technology

[0002] In the batch processing of drilling nameplate holes on the outer surface of arc-shaped gear pumps, the existing machining equipment and processes rely on manual hand-pressing. Each batch is processed individually, requiring a large number of personnel and resulting in high production costs. Furthermore, hand-pressing results in low clamping force, making it easy to drill off-center, which has always restricted the size and position of the product, leading to certain errors compared to the drawing requirements, and also poses a high risk factor.

[0003] When machining holes on curved surfaces, the unique shape of the product requires two people to work together, resulting in very high labor and costs. Existing machining fixtures are manually tightened with bolts or clamped in a vise. However, this method leads to problems such as drilling direction tilt and positional deviations, and the product accuracy is unstable. It is time-consuming and labor-intensive, causing some products to be defective or scrapped.

[0004] Existing equipment and processes for processing such products require one machine, one set of tooling, and two people to process only one piece at a time. This results in problems such as large batch processing errors, high production costs, low production efficiency, high labor costs, and unstable product quality. Summary of the Invention

[0005] To address the problems of existing technologies, this utility model provides a multi-station rotary tooling for an arc-shaped gear pump body, which enables rapid positioning and drilling of the arc-shaped surface of the gear oil pump body. The workpiece is fixed and disassembled quickly and stably, resulting in high work efficiency. This not only greatly reduces production costs but also improves machining accuracy.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A multi-station rotary fixture for an arc-shaped gear pump body includes a worktable, on which a base slides. A positioning disc is connected to the front vertical surface of the base via a rotary positioning shaft and a bearing shaft. The positioning disc rotates freely on the base, and a positioning mechanism is provided on the base outside the positioning disc to fix the rotating positioning disc in place. The workpiece to be processed is fixed in front of the positioning disc by a positioning locking bolt and a special pressure plate.

[0008] Preferably, the positioning plate is provided with positioning pin holes, which are used to insert positioning pins to position the workpiece to be processed.

[0009] Preferably, the positioning mechanism includes a guide seat fixed on the base, a positioning wedge inserted through the guide seat, a pull handle connected to the rear end of the positioning wedge, a return spring provided between the front part of the positioning wedge and the guide seat, and the positioning wedge protruding forward to engage with the positioning groove of the positioning disk, thereby achieving the positioning and fixing of the positioning disk.

[0010] Preferably, a support accessory is provided at the front of the base.

[0011] Preferably, an axial retaining ring is provided on the outside of the rotary positioning shaft.

[0012] The beneficial effects of the technical solution provided by this utility model are:

[0013] 1. The sliding base allows adjustment of the front and rear positions of the workpiece fixed on the base, facilitating drilling at multiple positions on the front and rear of the workpiece, avoiding multiple disassembly and assembly of the workpiece, and improving processing efficiency.

[0014] 2. The positioning plate can drive the circular pump body to rotate as a whole, so that the surface to be machined is facing the drill bit, and is positioned and fixed by the positioning mechanism. This allows for multi-position drilling on the outer surface of the pump body without disassembling the workpiece, further improving processing efficiency.

[0015] 3. The rapid positioning mechanism prevents the pump body from rotating during drilling, thus improving machining accuracy.

[0016] 4. The support attachments ensure that the entire base moves smoothly on the worktable and remains stable even when subjected to the drilling force of the drill bit, preventing it from tipping over and ensuring machining accuracy.

[0017] In summary, this utility model, through tooling and process optimization, increases the processing capacity per hour from 10 to 20 pieces, consolidates the original two workers into one, and allows for the simultaneous processing of multiple angled holes, completing production from raw material to finished product in a single operation. This not only improves processing efficiency and avoids risks such as bumps and scratches during processing, but also significantly reduces the labor intensity of workers and mitigates safety risks during processing. Using the composite tooling of this utility model enhances the safety and stability of product clamping, ensures the required shape and positional accuracy of the product, and significantly improves the product qualification rate. Upgrading the positioning mechanism enables rapid and convenient replacement of similar models of products, greatly reducing product production and processing time, shortening the supply cycle, and ensuring timely product delivery.

The workpiece 8 to be processed is fixed in front of the positioning disk 5 by a positioning locking bolt 6 and a special pressure plate 7.

[0024] In this embodiment, the positioning disk 5 is provided with a positioning pin hole 9, which is used to insert a positioning pin to position the workpiece 8 to be processed.

[0025] In this embodiment, the positioning mechanism includes a guide seat 10 fixed on the base 2, a positioning wedge 11 inserted through the guide seat 10, a pull handle 12 connected to the rear end of the positioning wedge 11, a return spring 13 provided between the front part of the positioning wedge 11 and the guide seat 10, and the positioning wedge 11 thrusts forward to engage the positioning slot 14 of the positioning disk 5, thereby achieving the positioning and fixing of the positioning disk 5.

[0026] In this embodiment, a support attachment 15 is provided at the front of the base 2.

[0027] In this embodiment, an axial retaining spring is provided on the outer side of the rotary positioning shaft 3 to maintain the elastic space between the positioning plate and the base.

[0028] This embodiment of a multi-station rotary fixture for an arc-shaped gear pump body utilizes the structure of the center of the workpiece 8, the arc shape, and the rotation center of the fixture. The positioning plate 5 and the base 2 are connected together by a rotary positioning shaft 3, an axial retaining spring, and a bearing 4, leaving a clearance. The guide seat 10 is fixed to the base 2 with hex bolts and positioning pins. Rotational positioning is achieved through the guide seat 10, positioning wedge 11, and pull handle 12 fixed to the base 2, and the positioning groove 14 on the positioning plate 5. Automatic locking is achieved through a return spring 13, coordinating to complete the rotation, positioning, clamping, and releasing actions. Then, the base 2 is placed on the sliding positioning worktable 1, and the workpiece 8 is fixed and locked to the positioning plate 5 using positioning pins, a special pressure plate 7, and locking bolts 6. Different positions of the workpiece are machined by positioning at different positions along the slide rail. To prevent the fixture from tilting when the base 2 slides on the worktable 1, a support attachment 15 is added, thus successfully achieving the machining of multiple positions and different angles of the workpiece with a single clamping operation.
