As shown in fig. 1-7, the utility model provides a milling machine fixture, its characterized in that, milling machine fixture includes:
the device comprises a base 10, wherein a positioning column 11 is arranged on the base 10;
one end of the first clamp component is fixed on the base 10, the other end of the first clamp component clamps the workpiece 40 from top to bottom, and the first clamp component can be detached and rotated; and
the second clamp assembly comprises a fixing plate 30, a screw rod 31 and a fixing cap 32, the fixing plate 30 is fixedly connected with the base 10, the fixing cap 32 is in threaded connection with the fixing plate 30, the screw rod 31 is in threaded connection with the fixing plate 30, one end of the screw rod 31 is inserted into the fixing cap 32, the number of the second clamp assemblies is at least two, and the two second clamp assemblies are respectively located on two sides of the workpiece 40 and clamp the workpiece 40.
Specifically, set up reference column 11 on base 10, reference column 11 is preferably no less than two, and the hole of inserting machined part 40 with reference column 11 on base 10 can carry out preliminary location to machined part 40, perhaps is a set of setting with two reference columns 11, and the distance between two reference columns 11 sets up according to machined part 40's width to just can put into machined part 40 and be preferred, and set up at least two sets of, carry out preliminary location to machined part 40.
The workpiece 40 is initially positioned by the positioning column 11, and the workpiece 40 is located between the two sets of second clamp assemblies. The connecting block 23 of the first clamp assembly is then pressed in place against the surface of the workpiece 40 and the connecting member 21 is secured with the bolt 22. After the workpiece 40 is further positioned and clamped in the vertical direction by the first clamp assembly, the screw rods 31 of the second clamp assemblies are respectively screwed through the fixing plates 30 so that the screw rods 31 apply pressure to the side surfaces of the workpiece 40, and then are screwed with the fixing plates 30 by the fixing caps 32, and one ends of the screw rods 31 are accommodated therein. After the fixing cap 32 is tightened, the screw 31 is further reinforced, so that even if the vibration is large during the machining process, the screw 31 is not loosened, and thus the workpiece 40 can be further reinforced and clamped from the horizontal direction. Under the clamping of multiple positioning, the clamping force of the embodiment is greatly enhanced.
In some embodiments, the first clamp assembly comprises: stand
A column 20, wherein the column 20 is fixed on the base 10;
the connecting piece 21 is provided with a strip-shaped through hole, and one end of the connecting piece 21, which is close to the workpiece 40, is also provided with a connecting block 23 which is in contact with the workpiece 40; and
a bolt 22;
the top end of the upright post 20 is inserted into the elongated through hole, and the bolt 22 passes through the elongated through hole and presses the connecting piece 21.
Specifically, the column 20 of the first clamp assembly includes a long column fixed on the base 10, which can be directly formed by an integral molding process during the production of the base 10, and a short column fixed on the top surface of the long column by conventional means such as screws, and the short column has a smaller diameter than the long column and can be inserted into the elongated through hole of the connecting member 21.
The width of the strip-shaped through hole is larger than the diameter of the short cylinder but smaller than the diameter of the long cylinder. Therefore, after the short column body is inserted into the elongated through hole, the connecting piece 21 is blocked by the long column body and cannot fall down continuously, and the connecting piece 21 can be adjusted in a rotating mode according to the position of the workpiece 40. The section of the connecting piece 21 close to the workpiece 40 is fixedly connected with a connecting block 23. The base 10 is provided with screw holes for matching with the bolts 22, so that the clamping effect is better.
In this embodiment, the height of the long column, together with the height of the workpiece 40 and the connecting piece 23, is preferably the same height, which allows the first clamp assembly to exert its maximum clamping force, since in this state the bottom surface of the nut and the top surface of the connecting piece 21 are in maximum contact.
In some embodiments, the first clamp assembly is at least one set.
In particular, the more the first clamp assembly is set, the greater the clamping force.
In some embodiments, the fixing plate 30 is provided with a threaded through hole.
In some embodiments, the fixing plate 30 is further provided with an annular protrusion 33, the outer side wall of the annular protrusion 33 is provided with a thread, and the annular protrusion 33 is coaxially arranged with the threaded through hole.
Specifically, the annular protrusion 33 and the threaded through hole are coaxially arranged, so that the screw 31 can be screwed through the annular protrusion 33 and the threaded through hole in order and abut against the workpiece 40.
In some embodiments, the surface of the end of the screw 31 that contacts the workpiece 40 is uneven.
Specifically, the surface of the screw 31 in contact with the workpiece 40 is provided with unevenness, and the friction force can be increased.
In some embodiments, the fixing cap 32 is open at one end and closed at the other end, and the inner side wall of the fixing cap 32 near the open end is provided with threads.
Specifically, the inner wall of the fixing cap 32 is threaded to match with the outer wall of the annular protrusion 33.
In some embodiments, the retaining cap 32 further includes at least one elongated groove formed in the inner sidewall thereof.
In some embodiments, a moving plate 34 is further disposed in the fixed cap 32, a moving protrusion matched with the elongated groove is disposed on a side wall of the moving plate 34, at least one spring 35 is further disposed in the fixed cap 32, one end of the spring 35 is fixedly connected to the moving plate 34, and the other end of the spring 35 is fixedly connected to the bottom surface of the fixed cap 32.
Specifically, there are two schemes for setting the depth of the fixing cap 32:
one is that the screw 31 just props against the fixed cap 32 after the screw is connected with the annular convex body 33;
alternatively, because the width of the workpiece 40 may vary, the fixing cap 32 of the first embodiment is too rigid, may not be able to abut against the screw 31, and may not perform the function of the fixing cap 32, so the moving plate 34, the spring 35 and the elongated groove may be disposed in the fixing cap 32, and have their cooperation, even when the fixing cap 32 is completely screwed with the annular protrusion 33, and the screw 31 cannot abut against the bottom surface of the fixing cap 32, the elastic force of the spring 35 may enable the moving plate 34 to abut against the screw 31, so as to adapt to workpieces 40 with various widths. And the movable convex body does not perform circular motion when being propped by the screw rod 31 to move in the fixed cap 32, and can only move along the elongated groove.
To sum up, the utility model comprises a base 10, wherein a positioning column 11 is arranged on the base 10; one end of the first clamp component is fixed on the base 10, the other end of the first clamp component clamps the workpiece 40 from top to bottom, and the first clamp component can be detached and rotated; and the second clamp assembly comprises a fixing plate 30, a screw rod 31 and a fixing cap 32, the fixing plate 30 is fixedly connected with the base 10, the fixing cap 32 is in threaded connection with the fixing plate 30, the screw rod 31 is in threaded connection with the fixing plate 30, one end of the screw rod 31 is inserted into the fixing cap 32, the number of the second clamp assemblies is at least two, and the two sets of the second clamp assemblies are respectively positioned on two sides of the workpiece 40 and clamp the workpiece 40. By adopting the design, the clamping force of the milling machine fixture is greatly enhanced, and the machined part is firmly fixed and is not easy to move in the machining process.
