[0002] In many existing fields such as construction, industry, and decoration, it is necessary to drill holes in some workpieces or parts, which requires the use of drilling equipment.

[0003] Currently, most drilling equipment uses hydraulic drilling equipment. However, conventional drilling equipment, especially small drilling equipment, only has the function of drilling holes. When multiple holes need to be drilled on a workpiece and there are certain requirements for the distance between the holes, such conventional drilling equipment is difficult to meet the accuracy requirements of drilling. The distance between adjacent holes needs to be controlled manually, resulting in low precision. Utility Model Content

[0004] The purpose of this invention is to provide an equally spaced angle clamping device for drilling holes, so as to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A bisector clamping device for drilling includes a worktable and a drilling device fixedly installed at the rear end of the top of the worktable. The front side of the drilling device is provided with fixed platforms at intervals. The bottom of the fixed platforms is detachably installed at the front end of the top of the worktable. A positioning plate is provided on the worktable. A first through hole is provided at the middle position of the top of the positioning plate. A turntable is rotatably installed in the first through hole. A chuck is detachably installed on the top of the turntable. The chuck is used to fix the workpiece.

[0007] The positioning plate has a plurality of first positioning holes circumferentially arranged on its side. The turntable includes a receiving part and a positioning part. The positioning part is integrally formed at the bottom center of the receiving part. The bottom side of the positioning part is provided with second positioning holes corresponding one-to-one with the plurality of first positioning holes.

[0008] By adopting the above technical solution, the first positioning hole on the positioning plate and the second positioning hole on the turntable cooperate. When the first positioning hole corresponds to the second positioning hole, the limiting device can pass through the first positioning hole and the second positioning hole to fix the turntable at a preset angle. The angle between the first positioning hole and the angle between the second positioning hole are consistent, which meets the needs of drilling. After the limiting device performs the limiting, it can also quickly end the limiting. The whole process is operated by mechanical devices, rather than relying on complex electrical equipment such as servo motors. Its stability and reliability are very high, and the cost is low.

[0009] In a further embodiment, the limiting device includes a T-shaped pin and a fixing block. The top of the fixing block is provided with multiple threaded holes. The fixing block is bolted to the fixing platform. A second through hole is provided on one side of the fixing block. The T-shaped pin is slidably installed in the second through hole. The T-shaped pin is used to cooperate with the first positioning hole and the second positioning hole to fix the turntable at a preset angle.

[0010] In a further embodiment, the fixed platform is provided with a plurality of first grooves running from front to back at intervals, the bottom side of the positioning disk is provided with a first extension portion extending horizontally, the first extension portion is provided with a first through groove, the other side of the bottom of the positioning disk is provided with a second extension portion extending horizontally, the second extension portion is provided with a second through groove, and bolt fastening devices are provided at both the first through groove and the second through groove, the bolt fastening devices being used to bolt and fix the positioning disk to the fixed platform.

[0011] In a further embodiment, the bolt fastening device includes a screw, a bolt, and a fixing plate. The fixing plate has a third through hole, in which the screw is inserted. The top end of the screw is provided with a bolt.

[0012] In a further embodiment, both the first through groove and the second through groove have acute-angled chamfered structures at their edges.

[0013] In a further embodiment, one end of the T-shaped pin is provided with a limiting buckle, and the inner top of the first through hole is provided with a second groove that cooperates with the limiting buckle.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. By setting up a turntable and a limiting device, the turntable can be fixed at a preset angle by using the cooperation of the first positioning hole on the positioning plate and the second positioning hole on the turntable. When the first positioning hole corresponds to the second positioning hole, the limiting device can pass through the first positioning hole and the second positioning hole. The angle between the first positioning hole and the second positioning hole is consistent, which meets the needs of drilling. After the limiting device performs the limiting, it can also quickly end the limiting. The whole process is operated by mechanical devices instead of relying on complex electrical equipment such as servo motors. While improving stability and reliability, it also greatly reduces processing costs.

[0016] 2. By using the T-shaped pin and the limit buckle, the upper part of the T-shaped pin can help the operator to control the pin more easily, and in conjunction with the limit buckle, it can lock as soon as it is rotated and release the limit when it is screwed back to the original position. The limit buckle can greatly improve work efficiency and prevent the pin from slipping.

[0017] 3. By setting up a fixed platform and a bolt fastening device, the position of the positioning plate can be moved by using the groove on the worktable, and the bolt fastening device can slide in the groove, so as to achieve the effect of freely adjusting the positioning position.

[0024] Example 1:

[0025] like Figures 1-3 As shown, a bisector clamping device for drilling includes a worktable and a drilling device fixedly installed at the rear end of the top of the worktable. A fixed platform 1 is spaced apart on the front side of the drilling device. The bottom of the fixed platform 1 is detachably installed at the front end of the top of the worktable. A positioning plate 2 is provided on the worktable. A first through hole is provided at the center of the top of the positioning plate 2. A turntable 3 is rotatably installed within the first through hole. A chuck 4 is detachably installed on the top of the turntable 3 for fixing the workpiece. Multiple first positioning holes are provided circumferentially on the side of the positioning plate 2. The turntable 3 includes a receiving part 31 and a positioning part 32. The positioning part 32 is integrally formed at the center of the bottom of the receiving part 31. Second positioning holes corresponding one-to-one with the multiple first positioning holes are provided at the bottom end of the side of the positioning part 32. A limiting device 5 is fixedly installed on one side of the fixed platform 1. The limiting device 5 includes a T-shaped pin 51 and a fixing block 52. Multiple threaded holes are provided on the top of the fixing block 52, and the fixing block 52 is bolted to the fixed platform 1. The fixing block 52 has a second through hole on one side. The edges of the first through groove and the second through groove are both provided with a blunted acute angle structure. A T-shaped pin 51 is slidably installed in the second through hole. The limiting device 5 is used to fix the workpiece at a specific angle. The T-shaped pin 51 is used to cooperate with the first positioning hole and the second positioning hole to fix the turntable at a preset angle. One end of the T-shaped pin 51 is provided with a limiting buckle 53. The top of the inner part of the first through hole is provided with a second groove that cooperates with the limiting buckle 53. After the workpiece is fixed by the claw 4, the turntable 3 can be rotated to make the second positioning hole on the positioning part 32 at the bottom of the turntable 3 cooperate with the first positioning hole on the positioning plate 2. After the workpiece is rotated to a suitable angle, the turntable 3 can be fixed by the T-shaped pin 51 through the first positioning hole and the second positioning hole. Then, a special drilling device is used to drill holes. The whole process is very convenient and fast, with high safety and stability. The operation is also very simple and requires less skill from the operator.

[0026] like Figures 1-3As shown, the fixed platform 1 has multiple first grooves spaced from front to back. The positioning disk 2 has a horizontally extending first extension on one side of its bottom, with a first through groove on the first extension. The positioning disk 2 has a horizontally extending second extension on the other side of its bottom, with a second through groove on the second extension. Both the first and second through grooves are equipped with bolt fastening devices 6. The bolt fastening device 6 includes a screw 62, a nut 61, and a fixing plate 63. The fixing plate 63 has a third through hole, into which the screw 62 is inserted. The top of the screw 62 is equipped with a nut 61. The bolt fastening device 6 is used to bolt and fix the positioning disk 2 to the fixed platform 1. Through the first and second extensions, as well as the first and second through grooves, after the extension is placed in a suitable position, the overall position of the positioning disk 2 can be adjusted by using the bolt fastening device 6 to fix it, effectively improving the flexibility of processing.

[0027] Specific implementation process: First, place the workpiece on the jaw 4 and fix it. Then, adjust the positioning plate 2 to a suitable position and align it with the first and second through slots on the fixed table 1. Then, use the bolt fastening device 6 to fix and limit the two. Use the T-shaped pin 51 on the limiting device 5 to pass through the first and second positioning holes for fixation. Then, start the drilling device to process. After processing one section, pull out the T-shaped pin 51, rotate the turntable 3, and align the next second limiting hole on the positioning part 32 with the first limiting hole again, so that the turntable 3 is fixed again and the hole is drilled. The limiting buckle 53 on the T-shaped pin 51 can ensure that it is rotated to a suitable position and fixed after insertion.
