Description

Technical Field

[0001] This utility model relates to the field of material transfer in machining, specifically a fixture for transferring gear blanks. Background Technology

[0002] After drilling and tapping, the 320 gear blanks in our gear factory need to be transferred to the gear cutting machine for milling. This requires manual handling and a 90-degree rotation for loading, unloading, and clamping. Because the blanks are large, weighing around 15KG, employees repeatedly perform this manual loading, unloading, and rotation work each shift, resulting in very high labor intensity. Initially, the factory sought external resources to design and manufacture lifting devices. The proposed solution used pneumatic clamping devices, which were complex and bulky, unsuitable for on-site use, and expensive. Utility Model Content

[0003] The present invention aims to overcome the shortcomings of the prior art and provide a fixture for transferring gear blanks.

[0004] This application provides the following technical solution: A clamp for transporting gear blanks is characterized in that: it includes a Y-shaped main body, a groove at one end of the Y-shaped main body, a slider in the groove, a hook on the slider, a latch hinged to the main body corresponding to the hook, an elongated hole in the groove, a clamp on the slider with one end extending out of the elongated hole, a clamp at each of the other two ends of the main body, a frame hinged to the main body, a lifting ring on the frame, and a spring pin corresponding to the main body.

[0005] Based on the above technical solutions, the following further technical solutions are also possible: The groove is provided with an elastic reset component that corresponds to and cooperates with the slider. It includes a guide post on the groove, a reset spring sleeved on the guide post, and a spring slot on the slider that corresponds to and cooperates with the reset spring.

[0006] The aforementioned chuck cone-shaped structure.

[0007] A bracket corresponding to and cooperating with the main body is connected across the other two ends of the main body.

[0008] Advantages of the utility model: This utility model has a simple structure and is easy to use. It can significantly reduce the labor intensity of employees. At the same time, by adding a fixed temporary placement platform on site, its production cycle will not change compared to manual handling. The lifting device adopts a pure mechanical linkage structure, which is lightweight and convenient. During operation, it can quickly clamp and rotate the tooth blank 90 degrees to lift it onto the workpiece fixture of the gear cutting machine for positioning and installation. Attached Figure Description

[0009] Figure 1 This is a three-dimensional schematic diagram of the present invention; Figure 2 This is a schematic diagram of the structure of this utility model; Figure 3 This is a three-dimensional schematic diagram of the present invention in operation; Figure 4 This is a schematic diagram when the frame is not connected to the main body. Detailed Implementation

[0010] like Figure 1-4 As shown, a jig for transferring gear blanks includes a Y-shaped body 1, a groove 2 at one end of the Y-shaped body 1, a slider 3 inside the groove 2, and a hook 5 on the slider 3.

[0011] A cover plate 1a is provided on the groove 2, and clearance holes 1b are provided on the cover plate 1a corresponding to the hook head 5. A latch 6 is hinged to the main body 1 and corresponds to the hook head 5. The latch 6 includes a pressing handle 6a and a rotatable locking ring 6b connected to the pressing handle 6a.

[0012] A long slot 2a is provided on the groove 2, and a chuck 4 is connected to the slider 3, with one end of the chuck 4 extending out of the long slot 2a. A chuck 4 is also provided at each of the other two ends of the main body 1. The three chucks 4 have the same structure, which is a frustum-shaped structure.

[0013] An elastic reset assembly corresponding to the slider 3 is provided in the groove 2. It includes a horizontally distributed guide post 10 extending from the groove wall at one end of the groove 2, a reset spring 11 sleeved on the guide post 10, and an inward spring slot 3a at the other end of the slider 3. One end of the reset spring 11 is inserted into the spring slot 3a and contacts its groove wall.

[0014] A frame 7 is hinged to the main body 1. An integrally formed lifting ring 9 extends outward from one end of the frame 7. A spring pin 8 is also installed on the frame 7, which corresponds to and engages with the locking hole 1c at one end of the main body 1. A lever 8a is hinged to the frame 7 on one side of the spring pin 8, which corresponds to and engages with the cap at the top of the spring pin 8. By pressing the lever 8a, the spring pin 8 can be easily pulled up, thereby unlocking the frame 7 from the main body 1.

[0015] A bracket 13, corresponding to and cooperating with the main body 1, is connected between the other two ends of the main body 1. The bracket 13 provides support to the other two ends of the main body 1 so that the entire device can be placed upright. This facilitates the hoisting and flipping of the device.

[0016] Usage process: Place the three chucks 4 on the outside of the tooth blank 12 to be transferred and make contact with the outer wall of the tooth blank 12. Then hook the locking ring 6b onto the hook head 5 and press down the handle 6a. During this process, the slider 3 moves in the groove 2 and is eventually locked. When locking the slider 3, the slider 3 will drive the chucks 4 on it to move inward, thereby clamping the tooth blank 12 located inside it through the three chucks 4.

[0017] Then, the frame 7 is rotated and locked to the main body 1 by the spring pin 8. Then, the entire clamp is erected. The operator can choose to directly lift the lifting ring 9 to transfer the device and its locked tooth blank 12, or hook the hook of the movable lifting tool at the work site into the lifting ring 9 and then transfer the device and its locked tooth blank 12.

[0018] After the tooling fixture of the gear blank 12 transfer equipment is in place and clamped, the device is laid down, the handle is lifted and the release lock 6 is released. The return spring 11 rebounds and pushes the slider 3 to move, thus completing the release of the gear blank 12.

[0019] Similarly, after the gear blank 12 is processed, the device is hoisted to the workpiece and the handle 6a is pressed to lock the slider 3. When locking the slider 3, the slider 3 will drive the chuck 4 on it to move inward, thereby clamping the gear blank 12 through the three chucks 4. After hoisting to the material rack, the locking pin is pressed and the handle is released. The main body 1 and the gear blank 12 rotate to a horizontal position under their own weight. After being placed at the positioning position of the material rack, the handle 6 is pressed to lift it up; the hook 5 is released, and the return spring 11 rebounds and pushes the slider 3 to move, thus completing the release of the gear blank 12.
