Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1-5, the present invention provides a workpiece fixture 500 for quickly fixing a machined workpiece. Specifically, the workpiece fixing device 500 of the present invention includes a base 100, and a rotating pressing mechanism 200 and a driving mechanism 300 respectively disposed on the base 100. Wherein, the base 100 is fixed on the worktable 101, and one side of the base 100 is attached to one side of the workpiece 102. The rotary pressing mechanism 200 is rotatably connected to the base 100, and the driving mechanism 300 is used for driving the rotary pressing mechanism 200 to rotate toward or away from the workpiece 102. When the rotary pressing mechanism 200 is rotated in a direction to approach the workpiece 102, the rotary pressing mechanism 200 converts the driving force of the driving mechanism 300 into a pressing force to press the workpiece 102 placed on the table 101 against the table 101.
In one particular embodiment, as shown in fig. 1 and 2, the pivoting hold-down mechanism 200 includes a lever bracket 210 and a lever press 220. Wherein the lever bracket 210 is fixedly provided on the base 100. The lever pressing block 220 is rotatably connected to the lever bracket 210. The first end of the lever pressing piece 220 can be driven by the driving mechanism 300 to rotate towards the direction close to the workpiece 102, so that the first end (i.e. the end B shown in fig. 1) of the lever pressing piece 220 is pressed onto the workpiece 102 to apply pressing force to the workpiece 102. Specifically, a first end (i.e., end B shown in fig. 1) of the lever press 220 presses against the upper surface of the workpiece 102.
As shown in fig. 2, the driving mechanism 300 includes a wedge block 310 movably disposed on the base 100, and when the wedge block 310 moves in a direction approaching the lever pressing block 220, the wedge block 310 extends below the second end (i.e., the end B shown in fig. 1) of the lever pressing block 220, so that the second end (i.e., the end B shown in fig. 1) of the lever pressing block 220 is lifted and the first end (i.e., the end B shown in fig. 1) thereof is pressed onto the upper surface of the workpiece 102.
As shown in fig. 1, showing the wedge block 310 extended below the second end of the lever pressing piece 220, the upper surface S of the wedge block 310 is configured as an inclined surface so that the wedge block 310 can be more easily extended below the second end of the lever pressing piece 220. During the moving process of the wedge block 310, as the wedge block 310 gets closer to the lever pressing block 220, the upper surface S thereof gets deeper below the second end of the lever pressing block 220, so as to lift the second end of the lever pressing block 220 higher; meanwhile, since the lever pressing block 220 is rotatably connected to the lever bracket 210, when the second end of the lever pressing block 220 is lifted, the first end (i.e., the end B shown in fig. 1) thereof moves toward the workpiece 102, i.e., the first end is pressed down, and if the second end of the lever pressing block 220 is lifted higher, the first end thereof is pressed down lower, so that the first end of the lever pressing block 220 is pressed against the upper surface of the workpiece 102, thereby fixing the workpiece 102 on the worktable 101.
Therefore, the workpiece fixing device 500 of the present invention achieves the purpose of fixing the workpiece 102 by using the force transmission mode, thereby greatly simplifying the operation steps; the problem that the traditional code pressing mode cannot be operated can be solved, so that the waiting time of the machine tool is shortened, and the machining efficiency is improved.
In some preferred embodiments, the first and second ends of the lever press 220 are each configured as arcuate ends. Since the second end of the lever pressing block 220 is the end contacting with the upper surface S of the wedging block 310, the second end of the lever pressing block 220 is configured as an arc-shaped end, which can facilitate the wedging block 310 to extend into the second end (end a) of the lever pressing block 220, and can avoid the phenomenon that the second end (end a) of the lever pressing block 220 cannot be lifted due to the wedging block 310 and the lever pressing block 220 being stuck.
In addition, since the first end (B end) of the lever pressing block 220 is the end in contact with the upper surface of the workpiece 102, the first end (B end) of the lever pressing block 220 is configured as an arc-shaped end, so that the lever pressing block 220 can form a line contact with the upper surface of the workpiece 102, and can be adapted to workpieces 102 with various heights, and the phenomenon that the workpiece 102 cannot be pressed with the surface of the workpiece 102 when the height of the workpiece 102 is high can be avoided.
Further, as shown in fig. 4, a horizontal section 221 and an inclined section 222 are provided between the first end (B end) and the second end (a end) of the lever pressing block 220 to be connected. It is understood that the lever pressing block 220 is connected to the lever bracket 210 by the pin 230 in a lever structure that is rotatably moved about the pin 230.
Wherein, the horizontal section 221 is rotatably connected with the lever bracket 210 through a pin 230; the inclined section 222 is inclined toward the direction close to the base 100. The provision of the inclined section 222 enables the lever press piece 220 to be adapted to workpieces 102 of different heights and to press the workpieces 102 more tightly against the table 101.
Furthermore, the size of the first end (B end) of the lever pressing block 220 is smaller than that of the second end (a end) thereof, and the second end (a end) of the lever pressing block 220 is heavier, so that when the wedge block 310 leaves the second end (a end) of the lever pressing block 220, the second end (a end) of the lever pressing block 220 can naturally lift up due to the loss of support and the heavier weight thereof, and can leave the workpiece 102 without manually separating from the workpiece 102.
So that when the workpiece 102 is not fixed by the lever pressing block 220 (as shown in fig. 3), the horizontal section 221 of the lever pressing block is kept parallel to the upper surface of the base 100, i.e. the lever pressing block 220 is kept at a balanced position,
the lever bracket 210 and the base 100 can be customized to match the size according to the thickness range and specific production requirement of the daily processed workpiece 102, and the present invention is not limited thereto. And the base 100 and the lever bracket 210 simultaneously determine the height of the workpiece 102 that can be fixed by the workpiece fixing device 500 of the present invention, thereby widening the application range thereof.
In one specific embodiment, the driving mechanism 300 further comprises a push rod 320 connected to the wedge block 310, the push rod 320 being used to push the wedge block 310 toward or away from the rotational pressing mechanism 200.

The wedge block 310 can be pushed to move toward or away from the lever pressing block 220 by screwing the push rod 320 into the first threaded hole 311 or screwing the push rod 320 out of the first threaded hole 311.
In addition, a support plate 110 is arranged on the base 100, a second threaded hole 111 is arranged on the support plate 110, and the push rod 320 passes through the second threaded hole 111 and then extends into the first threaded hole 311. Since the pushing rod 320 is also in threaded connection with the second threaded hole 111, when the pushing rod 320 pushes the wedge block 310 to a suitable position where the first end (B end) of the lever pressing block 220 can press the workpiece 102 against the worktable 101, the pushing rod 320 can be prevented from backing out of the wedge block 310 by the second threaded hole 111, and thus the pushing rod 320 can be fixed at a desired position by the threaded connection of the pushing rod 320 with the second threaded hole 111.
When the workpiece 102 is fixed, the pushing rod 320 is manually rotated by an operator to drive the wedging block 310 to move towards the direction close to the lever pressing block 220, and the force of manually rotating the pushing rod 320 is converted into the force of pressing the workpiece 102 by the lever pressing block 220 in an approximate transmission mode, so that a series of problems caused by manual fixation of each component by a screw and complicated operation in the conventional pressing method are thoroughly solved, and the efficiency of fixing the workpiece 102 in actual production is greatly improved.
