Description

Technical Field

[0001] This utility model relates to the field of auxiliary clamping, specifically a milling and turning auxiliary clamping device. Background Technology

[0002] In analytical equipment, a three-jaw chuck is usually used to clamp the workpiece. Next, locating pins need to be installed on the jaws. When clamping the workpiece, the locating pins are inserted into the nut flange hole to determine the circumferential angular position of the nut. Then, other circumferential machining operations of the nut are carried out according to the angular position of the nut flange hole. This ensures the angular relationship between the flange axial hole position and the nut radial machining operations.

[0003] However, during this process, locating pins must be installed on the chucks each time the product is processed. The installation position of the locating pins varies depending on the center distance of the nut flange holes, which causes the chucks to be drilled repeatedly to install locating pins, reducing the service life of the chucks and extending the machine adjustment time each time. Furthermore, the accuracy cannot be well controlled. Therefore, a milling and turning auxiliary fixture device is proposed to address the above problems. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problems of inconsistent center distances between nut flange holes and different locating pin installation positions, which lead to repeated drilling of the chucks to install locating pins, reducing the service life of the chucks, extending the time for each machine adjustment, and making it difficult to control accuracy, this utility model proposes a milling and turning auxiliary fixture device.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The milling and turning auxiliary fixture device of this utility model includes a fixed plate, a fixture body is fixedly connected to one side of the fixed plate, two elastic clamping bodies are provided on the fixture body, a locking screw is provided on one side of the fixture body, the locking screw is threadedly connected to the inside of the two elastic clamping bodies, an angle orientation groove is opened inside the fixture body, and a fastening component is provided on one side of the fixed plate, the fastening component is located inside the fixture body.

[0006] Preferably, the fastening assembly includes a fixed cylinder, a rotating shaft, two connecting rods, two locking balls, two branch ropes, and a connecting rope. The fixed cylinder is fixedly connected to one side of the fixed plate and is located inside the clamp body. The rotating shaft is fixedly connected inside the fixed cylinder. Both connecting rods are rotatably connected to the outside of the rotating shaft. The two locking balls are respectively fixedly connected to a section of the connecting rod. The two branch ropes are respectively fixedly connected to one side of the two connecting rods. One end of the connecting rope is fixedly connected to one end of the branch rope, and the other end of the connecting rope is fixedly connected to the outside of the locking screw.

[0007] Preferably, two symmetrically distributed connecting positioning pins are fixedly connected to one side of the fixing plate.

[0008] Preferably, the fixing plate is internally threaded with an adjusting screw that extends into the interior of the clamp body.

[0009] Preferably, the fixed cylinder has two symmetrically distributed waist-shaped holes on its exterior, and the locking ball extends through the workpiece body to the exterior of the fixed cylinder.

[0010] Preferably, a fixed pulley is provided inside the fixed cylinder, and a fixed pulley is provided at the bottom of the clamp body. The connecting rope passes through the two fixed pulleys and is connected to the locking screw.

[0011] The advantages of this utility model are:

[0012] 1. This utility model places the workpiece body inside the clamp body and fits it on the outside of the fastening assembly. The workpiece body is positioned by the angular orientation groove. One corner of the workpiece body is locked inside the angular orientation groove. Then, by rotating the locking screw, the two elastic clamps are brought closer together through the threaded engagement between the locking screw and the elastic clamp body, thus fixing the workpiece body. The position of the workpiece body can be adjusted by the setting adjustment screw. This reduces the angular error generated during clamping, enables the quick and accurate clamping of nuts, ensures the angular dimensions of the axial and radial processes of the nut, and improves clamping efficiency and angular accuracy.

[0013] 2. As the locking screw rotates, the connecting rope is pulled, which in turn pulls the two branch ropes. This causes the connecting rod to rotate in opposite directions, which in turn causes the locking ball to pass through the fixing cylinder and press against the inner wall of the workpiece. This further locks the workpiece body and improves the fixing effect. Attached Figure Description

[0021] During operation, when locking the workpiece, the workpiece is placed inside the fixture body 2 and fitted onto the outside of the fastening assembly 8. The angular orientation groove 6 is used to position the nut workpiece, with one corner of the nut workpiece locked inside the angular orientation groove 6. Then, by rotating the locking screw 4, the two elastic clamping bodies 3 are brought closer together through the threaded engagement between the locking screw 4 and the elastic clamping body 3, thus fixing the nut workpiece. The fastening assembly 8 can further fix the workpiece.

[0022] Furthermore, the fastening assembly 8 includes a fixed cylinder 801, a rotating shaft 802, two connecting rods 803, two locking balls 804, two branch ropes 805, and a connecting rope 806. The fixed cylinder 801 is fixedly connected to one side of the fixed plate 1 and is located inside the clamp body 2. The rotating shaft 802 is fixedly connected to the inside of the fixed cylinder 801. The two connecting rods 803 are rotatably connected to the outside of the rotating shaft 802. The two locking balls 804 are respectively fixedly connected to one end of the connecting rod 803.

One end of the connecting rope 806 is fixedly connected to one end of the branch rope 805, and the other end of the connecting rope 806 is fixedly connected to the outside of the locking screw 4.

[0023] During operation, as the locking screw 4 rotates, it pulls the connecting rope 806. This pulls the two branch ropes 805, causing the connecting rod 803 to rotate in the opposite direction. This causes the locking ball 804 to pass through the fixed cylinder 801 and press against the inner wall of the workpiece, thus further locking the workpiece.

[0024] Furthermore, two symmetrically distributed connecting positioning pins 5 are fixedly connected to one side of the fixing plate 1;

[0025] During operation, the device can be easily connected and positioned with other components via the connection and positioning pin 5.

[0030] Furthermore, a fixed pulley is provided inside the fixed cylinder 801, and a fixed pulley is provided at the bottom of the clamp body 2. The connecting rope 806 passes through the two fixed pulleys and is connected to the locking screw 4.

[0031] During operation, the fixed pulley guides the direction of the connecting rope 806 and reduces wear.

[0032] Working principle: When locking the workpiece, the workpiece body 9 is placed inside the clamp body 2 and fitted onto the outside of the fastening assembly 8. The workpiece body 9 is positioned by the angular orientation groove 6, with one corner of the workpiece body 9 locked inside the angular orientation groove 6. Then, by rotating the locking screw 4, the two elastic clamping bodies 3 are brought closer together through the threaded engagement between the locking screw 4 and the elastic clamping body 3, thus fixing the workpiece body 9. The position of the workpiece body 9 can be adjusted by the adjusting screw 7. As the locking screw 4 rotates, the connecting rope 806 is pulled, which in turn pulls the two branch ropes 805. This causes the connecting rod 803 to rotate in the opposite direction, which in turn causes the locking ball 804 to pass through the fixing cylinder 801 and press against the inner wall of the workpiece, thus further locking the workpiece body 9 and improving the fixing effect.
