[0001] This utility model relates to the field of fixture technology, specifically a drilling fixture for disc-shaped parts. Background Technology

[0002] For disc-shaped parts that require drilling in batches, the drilling fixtures currently used mainly consist of clamps and adjustable support beams. The drill bushing is installed on the support beam, and the drilling position can be quickly determined by adjusting the drill bit of the drilling machine to extend into the drill bushing, thus improving processing efficiency.

[0003] However, when changing the position of disc-shaped parts of different sizes or machining holes, the position of the support beam needs to be adjusted. This involves disassembly and repositioning via bolt connections, which is cumbersome. Furthermore, when the hole diameter changes, the corresponding drill bushing also needs to be replaced, resulting in poor operational flexibility.

[0004] Therefore, in order to solve the above problems, a drilling fixture for disc-shaped parts is proposed. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 This utility model provides a technical solution: a drilling fixture for disc-shaped parts, including a base 7, which is an integral part consisting of a horizontal plate and vertical plates fixedly installed at both ends of the horizontal plate. The base 7 serves as the mounting base for other components.

[0019] A fixed clamp 10 is installed on one end of the upper surface of the base 7 by means of bolts, and a movable clamp 8 is installed on the other end of the upper surface of the base 7 by means of translation component 6. V-shaped grooves are opened at the ends of the fixed clamp 10 and the movable clamp 8 that are close to each other. The included angle between the two sides of the V-shaped groove is preferably 90°, so that the force is more even when clamping. The movable clamp 8 can be translated by the translation component 6 to realize the opening and closing action of the movable clamp 8 and the fixed clamp 10, thereby completing the clamping and removal of disc-shaped parts. It can clamp and fix disc-shaped parts of different diameters.

[0020] A center plate 3 is installed on the end of the base 7 near the fixed clamp 10 via a switching assembly 2. A support beam 4 is fixedly installed on the circumference of the center plate 3. The support beam 4 has several through holes, and drill sleeves 5 are inserted into each through hole. The drill sleeves 5 are made of cemented carbide material, which has good hardness and wear resistance. They are used to position the drill bit. Different support beams 4 can be switched on the disc-shaped parts via the switching assembly 2. The corresponding drill sleeves 5 are used to assist in positioning, which can improve work efficiency.

[0021] The support beams 4 are arranged in two to four circumferentially, providing more installation positions within a limited space and increasing the number of drill sleeves 5 that can be installed, thus meeting the drilling needs of more disc-shaped parts of various sizes.

[0022] Please see Figure 2 The switching component 2 includes a rectangular block 21, a rotating joint 22, a rotating shaft 23, and a vertical plate 24. A pair of vertical plates 24 are fixedly installed on the end of the base 7 near the fixed clamp 10. The vertical plates 24 are vertically arranged, and the same rotating shaft 23 is rotatably installed between the vertical plates 24. The rectangular block 21 is rotatably installed above the rotating shaft 23 via the rotating joint 22. The rectangular block 21 is fixedly assembled to the center plate 3 via a connecting rod. The rectangular block 21 is snapped between the vertical plates 24. The rotating joint 22 is an existing component assembled by rotating two rotating seats, which can realize relative circumferential rotation at both ends.

[0023] The pivot 23 allows the components on it to swing, while the pivot joint 22 allows the components on it to rotate circumferentially to meet the switching requirements of each support beam 4; the rectangular block 21 is square when viewed from above, so that the rectangular block 21 has four insertion directions that cooperate with the upright plate 24, and each support beam 4 corresponds to a side of the rectangular block 21. Every 90° rotation can switch a corresponding support beam 4 to be located on the disc-shaped part.

[0024] A pin 12 is fixedly installed at the end of the base 7 near the fixing clamp 10. The upright plate 24 has a round pin hole for aligning with the pin in the pin 12, and the rectangular block 21 has a cross-shaped pin hole. The pin 12 is an existing component consisting of a pin seat, a pin, a handle, and two slots at the bottom of the pin seat. The handle can be switched to different slots to adjust the length of the pin extending out of the pin seat. After the pin passes through the round pin hole and the cross-shaped pin hole, it can fix the rectangular block 21. Only after the pin separates from the cross-shaped pin hole can the rectangular block 21 swing out from between the upright plates 24.

[0025] Please see Figure 3 The translation component 6 includes a bearing seat 61, a screw 62, and a handwheel 63. The base 7 has a first screw hole at the end near the movable clamp 8, and the screw 62 is screwed into the first screw hole. The bearing seat 61 is fixedly installed at the end of the movable clamp 8 away from the fixed clamp 10. One end of the screw 62 is rotated and assembled with the bearing seat 61 through a bearing, and the other end of the screw 62 is fixedly installed with a handwheel 63. The screw 62 can be rotated by the handwheel 63, and the translation position of the bearing seat 61 in the left and right directions can be adjusted through the screw connection, thereby completing the purpose of translating the movable clamp 8.

[0026] The translation component 6 also includes guide blocks 64. A pair of guide blocks 64 are fixedly installed on the upper surface of the base 7. The movable clamp 8 has a dovetail-shaped cross-section. The side walls of the guide blocks 64 that are close to each other are provided with guide grooves that match the movable clamp 8. The movable clamp 8 is slidably assembled between the guide grooves. By cooperating with the guide grooves, the stability of the movable clamp 8's translation can be improved, ensuring the smooth completion of clamping and releasing actions.

[0027] A chip discharge port 9 is provided at the center of the base 7. A base 11 is fixedly installed below the base 7 by a support column. The base 11 has countersunk holes that match the drilling platform. The base 11 can be fixedly installed by bolts. The support column provides sufficient distance between the base 7 and the base 11 to meet the operating space requirements of the support beam 4. In addition, during drilling, the generated chips can be discharged downward from the chip discharge port 9 without affecting the drilling operation and improving the drilling quality.

[0028] The support beam 4 has a second screw hole. Each through hole has a second screw hole on one side. A positioning screw 1 is screwed into each second screw hole. A groove is opened on the circumferential side of the drill sleeve 5. The nut of the positioning screw 1 is engaged in the groove. After the positioning screw 1 is tightened, it is engaged in the groove, which can press the drill sleeve 5 and prevent the drill sleeve 5 from rotating circumferentially. The drill sleeve 5 in the through hole can be replaced after the positioning screw 1 is removed. It is flexible and convenient to use.

[0029] The working principle of this embodiment: When in use, first place the disc-shaped part on the base 7, between the V-shaped grooves on both sides, and then move the movable clamp 8 towards the fixed clamp 10 through the translation component 6 until the disc-shaped part is clamped. After the pin 12 is operated to separate the pin from the cross-shaped pin hole, the rectangular block 21 is swung counterclockwise from the vertical plate 24 by the hand holding the center plate 3. After rotating the rectangular block 21, it is re-inserted clockwise to switch the corresponding support beam 4. After the rectangular block 21 is re-locked by the pin 12, the corresponding drill sleeve 5 can be quickly adjusted to the use position, which facilitates the quick positioning of the drill bit of the drilling machine and improves the convenience and flexibility of use. After drilling is completed, the movable clamp 8 is moved away from the fixed clamp 10 by the translation component 6 to remove the disc-shaped parts after drilling.
