[0002] A milling machine mainly refers to a machine tool that uses a milling cutter to process various surfaces of a workpiece. Usually, the rotation of the milling cutter is the main motion, and the movement of the workpiece and the milling cutter is the feed motion.

[0003] When a milling machine processes a plate, it needs to use a fixture to fix the plate first. Traditional fixtures are mostly fixed by clamping. When fixing, the plate is completely fixed on the surface of the workbench. When one surface of the plate is processed, it is usually necessary to disassemble the plate and turn it over before processing. The process of disassembly and fixing is itself cumbersome, and because the fixing itself is manually operated, there is bound to be a problem of position offset. After the position is offset, it needs to be re-positioned before processing can be carried out;

[0004] The process of disassembly, reinstallation and repositioning requires a lot of time. Therefore, when processing different surfaces of the same plate, the above-mentioned traditional tooling fixture requires a lot of operation time, which makes the processing efficiency of the plate relatively reduced. Therefore, a flip-type tooling fixture is proposed to solve the above-mentioned problems. Utility Model Content

[0030] See also Figure 1 , Figure 5 and Figure 6 , a flip-type fixture, comprising:

[0031] The fixing fixture is arranged on the surface of the milling machine operating table 1 through a positioning threaded sleeve 7, and comprises a fixing housing 3, a lower pressing plate 5, a pressure spring 6 and a positioning threaded sleeve 7, wherein:

[0032] The fixed housing 3 comprises a main housing 31, a dovetail block 32 is provided at the bottom end of the main housing 31, a first threaded column 34 is provided at the top end of the dovetail block 32, a slot 36 and a limit opening 37 are provided at one side of the main housing 31 close to the plate 2, a rectangular hole 35 is provided on the upper surface of the main housing 31, a top cover 33 is provided at the top end of the rectangular hole 35, a lower pressure plate 5 is provided inside the rectangular hole 35, and a pressure spring 6 is provided between the lower pressure plate 5 and the top cover 33;

[0033] The top of the lower pressing plate 5 is provided with a cylindrical protrusion, and both sides of the lower pressing plate 5 are inclined surfaces;

[0034] Based on the above, the positioning threaded sleeve 7, the dovetail block 32 and the first threaded column 34 cooperate with each other. When the dovetail block 32 is set inside the dovetail groove on the surface of the milling machine operating table 1, the fixed shell 3 is fixed to the upper surface of the milling machine operating table 1 by tightening the positioning threaded sleeve 7. The setting of the lower pressure plate 5 makes the plate 2 be squeezed when inserted into the limiting opening 37. The squeezed lower pressure plate 5 moves upward to compress the pressure spring 6, so that the lower pressure plate 5 is tightly fitted with the surface of the plate 2 under the action of the downward elastic force, so as to achieve preliminary fixation of the plate 2.

[0035] like Figure 2-Figure 4 As shown, the clamping block 4 is connected to the plate 2 through the upper clamping plate 8 and the clamping threaded sleeve 9, and the clamping block 4 includes a rectangular block 41, and the rectangular block 41 is provided with a clamping bottom plate 43 near the plate 2, and the top and bottom ends of the clamping bottom plate 43 are respectively provided with a second threaded column 45 and a lower baffle 44, and one end of the rectangular block 41 is provided with a movable groove 42 and a side cover 46;

[0036] Based on the above, the second threaded column 45 cooperates with the clamping thread sleeve 9. When the plate 2 is set between the upper clamping plate 8 and the clamping base plate 43, by tightening the clamping thread sleeve 9, the upper clamping plate 8 and the clamping base plate 43 are respectively tightly fitted with the upper and lower surfaces of the plate 2 to achieve the connection and fixation between the clamping block 4 and the plate 2.

[0037] like Figure 1-Figure 3As shown, the locking mechanism is arranged inside the clamping block 4 and includes a main spring 10, a toggle block 11 and a locking block 12. The movable groove 42 is provided with a locking block 12, the locking block 12 passes through the side cover 46 and extends to the inside of the locking groove 36, the side of the locking block 12 away from the toggle block 11 is provided with an inclined side surface, the toggle block 11 is provided on the side of the locking block 12 away from the clamping bottom plate 43, and the main spring 10 is provided between the locking block 12 and the rectangular block 41;

[0038] Based on the above, the locking mechanism and the fixing clamp cooperate with each other to fix the plate 2. After the plate 2 and the connecting clamp are connected and fixed to each other, the plate 2 is inserted from the limiting opening 37. During the insertion process, the inclined side of the block 12 is squeezed against the main shell 31. After squeezing, the block 12 moves laterally to squeeze the main spring 10. When the block 12 moves to the inside of the slot 36, the block 12 is reset under the action of the elastic force of the main spring 10, so that the position of the connecting clamp is fixed. At this time, the lower baffle 44 fits tightly with the main shell 31, thereby achieving the effect of fixing the plate 2.

[0039] In actual use, the present embodiment is provided with the connecting fixture at the two corners of the plate 2, and the positioning threaded sleeve 7 and the first threaded column 34 cooperate with each other so that the fixing fixture is fixed on the surface of the milling machine operating table 1, such as Figure 7 As shown;

[0040] At this time, the milling machine can operate on the upper surface of the plate 2. In actual needs, it may be necessary to adjust the plate 2 so that Figure 7 The upper surface of the middle plate 2 is turned over to become the lower surface, that is, turned over 180 degrees, and the other surface is processed;

[0041] During the flipping process, the toggle block 11 is toggled so that the toggle block 11 drives the clamping block 12 to move in the direction of approaching each other. At this time, the clamping block 12 compresses the main spring 10 and separates from the clamping slot 36. Then, the connecting clamp and the plate 2 are pulled out from the limiting opening 37. After being pulled out, they are flipped 180 degrees with AB as the axis. After the plate 2 is flipped 180 degrees, the connecting clamp is still located on the side of the B end. After the angle is flipped, the plate 2 is inserted into the limiting opening 37 again.

[0042] Insertion is the sheet 2 pressing the lower pressing plate 5. Since both sides of the lower pressing plate 5 are impact surfaces, there is a vertical component force after being pressed. The lower pressing plate 5 moves vertically under the component force, that is, it presses the pressure spring 6. When the sheet 2 is inserted under the lower pressing plate 5, it is acted upon by the elastic force of the pressure spring 6, so that the position of the sheet 2 is fixed.

[0043] In actual operation, there is a need to rotate the plate 2 180 degrees with the vertical line of the upper surface of the milling machine operating table 1 as the center of the circle, that is, the side of the installation connection fixture is rotated from the B end to the A end. At this time, the upper surface of the plate 2 is still facing upward, but its angle has changed. This process is consistent with the above-mentioned extraction process. After the plate 2 is extracted, it can be inserted from the limit opening 37 on the side of the A end.

[0044] Compared with traditional tooling fixtures, this tooling fixture adopts a clamping method for fixing. The fixing fixture is used to limit the plate 2, so that the plate 2 can only move along the direction of the limiting opening 37. The lower pressure plate 5 and other structures prevent the plate 2 from moving upward. The clamping mechanism and the clamping groove 36 cooperate with each other to limit the plate 2 in the direction of the limiting opening 37, thereby achieving the effect of completely fixing the plate 2. During actual processing, the plate 2 can be adjusted by pulling it out and then fixing it, so that the plate 2 can be turned over and then processed again. Since the tooling fixture is completely in line with the surface shape of the plate 2, it is still applicable after turning over, and there will be no positional offset, that is, there is no need for secondary positioning. Compared with the traditional tooling fixture that needs to be disassembled, reinstalled and repositioned, the time consumed is greatly reduced, thereby increasing work efficiency.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
