Description

Technical Field

[0001] This utility model relates to auxiliary tooling for clamping large narrow-faced workpieces on vertical lathes in the field of workpiece machining technology. Background Technology

[0002] Vertical lathes are used for cutting and machining the outer surface of workpieces. Four clamping mechanisms are symmetrically arranged on the worktable of a vertical lathe. The front of the clamping heads of these mechanisms presses against the outer periphery of the workpiece, and the four clamping heads work together to clamp and fix the workpiece. Simultaneously, the bottom side of the workpiece is supported by a cylindrical support block. The lathe tool then machines the workpiece, ensuring its stability and preventing displacement during machining. However, some workpieces have a narrow bottom on their outer periphery, causing part of the cylindrical support block to protrude from the bottom of the workpiece. This could lead to the lathe tool coming into contact with the cylindrical support block during machining, posing a safety hazard. Utility Model Content

[0003] The purpose of this invention is to provide an auxiliary tooling for clamping large workpieces with narrow faces on a vertical lathe. It can support the narrow face at the bottom of the workpiece without exceeding its range, thus preventing contact with the cutting tool and ensuring high safety.

[0004] To achieve the above objectives, this utility model provides an auxiliary tooling for clamping large workpieces with narrow surfaces on a vertical lathe, including a base, a fastening structure at one end of the base, and a support structure at the other end of the base. The fastening structure matches a locking groove opened on the work platform.

[0005] Compared with the prior art, the beneficial effect of this utility model is that by inserting the lower part of the fastening structure into the locking groove, and placing the base on the working platform, after moving the base along the locking groove to the designated position, the fastening structure locks and fixes the base on the working platform. The support structure can be used to support the narrow bottom surface of the workpiece, and the clamping mechanism can clamp and fix the workpiece. This can support the narrow bottom surface of the workpiece without exceeding its range, thus preventing contact with the cutting tool and ensuring high safety.

[0006] As a further improvement of this utility model, the support structure includes a support screw, the lower end of which matches the support screw hole opened on the base, and a support nut is threaded onto the support screw, with the support nut located above the base.

[0007] This allows you to adjust the height of the support screw extending above the base by screwing it according to the size of the workpiece, so as to suit the height of the bottom of the workpiece from the working platform. Then, screw the support nut to lock the support screw in place, preventing it from shifting downwards due to the force applied during workpiece processing.

[0008] As a further improvement of this utility model, the fastening structure includes a fastening bolt. The lower end of the fastening bolt passes through the base and is threadedly connected to a fastening screw hole opened on the fastening block. The fastening block matches the locking groove. A fastening nut is also threaded onto the fastening bolt and is located above the base.

[0009] After the fastening block is inserted into the locking groove and moved to the designated position along the locking groove, the fastening bolt is screwed to the bottom of the fastening screw hole, and then the fastening nut is screwed on, thereby firmly pressing the base onto the working platform.

[0010] As a further improvement of this utility model, the fastening groove is processed into an inverted T-shaped groove. The vertical part of the inverted T-shaped groove matches the support screw and the fastening bolt, and the horizontal part of the inverted T-shaped groove matches the fastening block.

[0011] The horizontal part of the inverted T-shaped groove fits snugly against both ends of the fastening block, making it easy to tighten the bolts and preventing rotation problems during the tightening process.

[0012] As a further improvement to this invention, the upper outer periphery of the support screw is machined into a hexagonal structure. This facilitates tightening the support screw using tools such as wrenches.

[0013] As a further improvement of this utility model, the support screw hole penetrates the base.

[0014] This allows the height of the support screw above the base to be adjusted, thus better accommodating workpieces of different sizes that can be processed. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] like Figure 1-5 The auxiliary tooling for clamping large workpieces with narrow faces on a vertical lathe, as shown, includes a base 2. One end of the base 2 has a fastening structure, and the other end has a support structure. The fastening structure matches a locking groove 7 on a work platform 8. The support structure includes a support screw 6, the lower end of which matches a support screw hole on the base 2. A support nut 5 is threaded onto the support screw 6, and the support nut 5 is located above the base 2.

[0023] The fastening structure includes a fastening bolt 4. The lower end of the fastening bolt 4 passes through the base 2 and is threadedly connected to the fastening screw hole opened on the fastening block 1. The fastening block 1 matches the locking groove 7. The fastening bolt 4 is also threaded with a fastening nut 3, which is located above the base 2.

[0024] The fastening groove is machined into an inverted T-shape. The vertical part of the inverted T-shape matches the support screw 6 and the fastening bolt 4, while the horizontal part matches the fastening block 1. The upper outer periphery of the support screw 6 is machined into a hexagonal structure. The support screw hole penetrates the base 2.

[0025] In this utility model, each pair of clamping mechanisms 10 is provided with an auxiliary tool, and a total of four are provided and are symmetrical to each other.

[0026] In use, the fastening bolt 4 is first screwed onto the fastening nut 3, then the lower end of the fastening bolt 4 is inserted into the base 2 and extends outward, and is screwed onto the fastening screw hole on the fastening block 1. At the same time, the fastening nut 3 is above the base 2, and the support screw 6 is screwed onto the support nut 5. The lower end of the support screw 6 is screwed into the support screw hole on the base 2, and the support nut 5 is above the base 2.

[0027] After the main body of the auxiliary tooling is assembled, the fastening block 1 is inserted into the horizontal part of the inverted T-shaped groove, and the lower part of the fastening bolt 4 is in the vertical part of the inverted T-shaped groove. The base 2 is pushed to move along the inverted T-shaped groove to the predetermined position, which is estimated by the size of the workpiece 11 being processed, so that the top of the support screw 6 can be directly below the bottom of the workpiece 11.

[0028] Tighten the fastening bolt 4. Since the two ends of the fastening block 1 are attached to the two sides of the horizontal part of the inverted T-shaped groove, it will not rotate during the tightening process. After the fastening bolt 4 is tightened to the bottom of the fastening screw hole, tighten the fastening nut 3, so that the fastening nut 3 moves downward along the fastening bolt 4 until it presses against the base 2, thereby pressing and fixing the base 2 onto the work platform 8. Then, according to the size of the workpiece 11, tighten the support screw 6 to adjust the height of the support screw 6 so that the clamping heads 9 of the other clamping mechanisms 10 match. After adjustment, tighten the support nut 5, so that the support nut 5 moves downward along the support screw 6 until it presses against the base 2, thereby limiting the position of the support screw 6 and preventing it from moving up and down.

[0029] The workpiece 11 is transported to the top of the vertical car by the overhead crane and slowly lowered onto the support screw 6. Since the bottom of the workpiece 11 is relatively narrow, the position of the base 2 on the working platform 8 and the height of the support screw 6 can be readjusted so that the top of the support screw 6 is in complete contact with the bottom surface of the workpiece 11. At the same time, the clamping head 9 is also facing the side of the workpiece 11 to completely clamp and fix the workpiece 11. The workpiece 11 is then machined with a lathe tool.

[0030] Once the auxiliary tooling is adjusted, its position will not need to be adjusted again as long as the same model and specification of workpiece 11 is being processed, and it can be used continuously.

[0031] This utility model is easy to operate and has a simple structure. It can assist the clamping mechanism 10 of the vertical lathe in supporting and clamping the workpiece 11 without affecting the movement of the cutting tool. The workpiece 11 is stably supported, effectively ensuring machining accuracy and improving safety.

[0032] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed herein, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
