[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0030] See also Figures 1 to 6 , which is a bidirectional positioning milling fixture of an embodiment of the utility model, includes a base 10, a first positioning component 20 installed on the base 10, and a second positioning component 30 installed on the base 10.
[0031] The base 10 includes a bottom plate 11, and an adapter block 12 fixedly mounted in the middle of the top surface of the bottom plate 11; a first assembly hole 13 is provided inwardly at one end of the adapter block 12, and a second assembly hole 14 is provided inwardly on the top surface of the adapter block 12. The axis of the first assembly hole 13 is arranged in the horizontal direction, and the first assembly hole 13 is used to connect the first positioning component 20; the axis of the second assembly hole 14 is arranged in the vertical direction, and the second assembly hole 14 is used to connect the second positioning component 30.
[0032] In this embodiment, the first assembly hole 13 and the second assembly hole 14 are both internal thread holes.
[0033] The first positioning assembly 20 includes a first movable clamping block 21 detachably connected to the first assembly hole 13, a first fixed clamping block 22 installed at the other end of the adapter block 12, a first spring 23 sandwiched between the first movable clamping block 21 and the adapter block 12, and support protrusions 24 installed on opposite sides of a side of the first movable clamping block 21 facing the first fixed clamping block 22; the support protrusions 24 are used to abut against the product 40. The first movable clamping block 21 and the first fixed clamping block 22 are arranged facing each other, and the first movable clamping block 21 and the first fixed clamping block 22 are used to clamp the product 40 along the horizontal direction.
[0034] Specifically, the support protrusions 24 are arranged in pairs on opposite sides of the first movable clamping block 21, that is, each side of the first movable clamping block 21 has two support protrusions 24. The angle between the axis lines of the two support protrusions 24 on the same side of the first movable clamping block 21 is in the range of 80-120 degrees. Furthermore, the support protrusions 24 are provided with anti-slip grooves on one side for contacting the product 40.
[0035] In this embodiment, a first screw rod 210 is rotatably mounted in the middle of the first movable clamping block 21, and the first screw rod 210 is matched and connected to the inside of the first assembly hole 13 to achieve the connection between the first movable clamping block 21 and the adapter block 12. The first spring 23 is sleeved with the first screw rod 210.
[0036] In this embodiment, each first fixed clamp block 22 has a limit slot 220 on one side facing the first movable clamp block 21 , and the limit slot 220 is substantially V-shaped and arranged opposite to the support protrusion 24 , and is used to limit the product 40 .
[0037] The second positioning assembly 30 includes a second movable clamp block 31 detachably connected to the second assembly hole 14, second fixed clamp blocks 32 installed on opposite sides of the bottom surface of the adapter block 12, and a second spring 33 sandwiched between the second movable clamp block 31 and the adapter block 12. The second movable clamp block 31 and the second fixed clamp block 32 are arranged facing each other, and the second movable clamp block 31 and the second fixed clamp block 32 are used to clamp the product 40 along the vertical direction.
[0038] Specifically, the middle part of the second movable clamping block 31 is rotatably mounted with a second screw rod 310, which is matched and connected to the inside of the second assembly hole 14 to achieve the connection between the second movable clamping block 31 and the adapter block 12. The second spring 33 is sleeved with the second screw rod 310.
[0039] In this embodiment, the second fixed clamp block 32 is arranged in a "convex" shape. The second movable clamp block 31 is provided with receiving grooves 311 on opposite sides of a side facing the second fixed clamp block 32. The receiving grooves 311 correspond to the second fixed clamp block 32 one by one. The receiving grooves 311 and the second fixed clamp block 32 are used to position the product 40 to increase the clamping force and prevent the product 40 from shifting.
[0040] When working, first remove the first movable clamp block 21 and the second movable clamp block 31, place the product 40 on the base 10, and perform preliminary alignment through the first fixed clamp block 22 and the second fixed clamp block 32, and then install the first movable clamp block 21 and the second movable clamp block 31 on the adapter block 12 respectively, and tighten the first movable clamp block 21 and the second movable clamp block 31. At this time, the first movable clamp block 21 and the first fixed clamp block 22 clamp the adapter block 12 in the horizontal direction, and the second movable clamp block 31 and the second fixed clamp block 32 clamp the adapter block 12 in the vertical direction, which can simultaneously apply horizontal and vertical clamping forces to the product 40 to achieve bidirectional positioning. Compared with traditional one-way clamps, it effectively reduces the clamping time and greatly improves the processing efficiency.
[0041] Among them, behind the first screw 210, the first spring 23 will generate a continuous elastic force, so that a friction force is continuously maintained between the first screw 210 and the thread of the first assembly hole 13, generating a resistance torque, thereby preventing loosening and improving the stability of the screw connection; the same is true for the second screw 310.
[0042] The above-mentioned bidirectional positioning milling fixture has a simple structure and is easy to use. The base 10 is provided with a first positioning component 20 and a second positioning component 30, which can simultaneously apply horizontal and vertical clamping forces to the product 40 to achieve bidirectional positioning, effectively reduce clamping time, and greatly improve processing efficiency.
[0043] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0044] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
