Description

Fixation fixture

The invention relates to a fixture, in particular to a fixture for fixing a mold into a sub-process.

Conventional mold insert parts need to be adapted to different types of molds, requiring a large amount of regular processing. Due to the material properties of the mold, the mold is required to be electric discharge machining. The conventional method is to adsorb the inlet to the magnetic platform of the electric discharge machine. In order to ensure that the sub-parts are not loose during the processing, it is sometimes necessary to add a strong glue to the magnetic platform for bonding. The process of fixing the conventional method requires the EDM machine to stop waiting during the installation process, which reduces the utilization rate of the machine, and the clamping efficiency is low due to the manual clamping.

In view of the above, it is necessary to provide an intruding fixture.

A fixture for fixing a fixture for fixing at least one inlet, the fixture for fixing the fixture includes a fixture platform, a back plate, a plurality of positioning stops, a pressing plate and a cylinder, and the supporting plate is fixed on the fixture platform, a plurality of positioning stops abut against the backing plate and spaced apart, the plurality of positioning stops for abutting the at least one inlet, the cylinder connecting the pressing plate and pushing the pressing plate to move toward the backing plate to At least one of the inserts is fixed between the backing plate and the pressing plate.

In one embodiment, the backing plate is provided with a positioning plane, and the plurality of positioning stops abut against the positioning plane.

In one embodiment, each of the positioning stops includes two side walls that are substantially perpendicular to the positioning plane.

In one embodiment, the distance between each two adjacent positioning stops is equal.

In one embodiment, the distance between each two adjacent positioning stops is approximately 40 millimeters.

In one embodiment, the fixture platform includes a bearing plane, the positioning block is located on the bearing plane, and a fastening space for receiving the inlet is disposed between the backing plate and the bearing plane.

In one embodiment, the insert fixture further includes a shoulder pressing plate that can fix the at least one insert protruding into the fastening space to the carrying platform.

In one embodiment, the shoulder pressing plate is movable in a direction substantially perpendicular to the carrying platform, and the shoulder pressing plate has a substantially L-shaped cross section.

In one embodiment, the fixing fixture further includes two guiding fixing blocks and two guiding rods, and the two guiding rods are respectively connected to the two guiding fixing blocks and the two positioning stops, and the pressing plate is slidably fixed on the two guiding rods. .

In one embodiment, the pressing plate comprises a plurality of elastically stretchable pressing blocks.

Compared with the prior art, the insert fixing fixture can realize quick clamping of the insert and improve the fixing efficiency. The installation of the inlet into the predetermined position reduces the calculation of the input sub-measurement and the machining position coordinates. The insert fixing fixture can fix the insert before using the electric discharge machine, which reduces the downtime of the electric discharge machine and improves the utilization rate.

Fig. 5 is a perspective view of the insert fixing fixture of Fig. 4 when the insert is fixed.

Figure 6 is a side view of Figure 5.

Referring to FIG. 1 to FIG. 3 , in one embodiment, an insertion fixture is used to fix the plurality of inlets 100 . The fixture fixture includes a fixture platform 10, a backing plate 30, a plurality of positioning stops 50, a shoulder pressing plate 40, a pressing plate 60, two guiding fixing blocks 70, two guiding rods 75 and a cylinder 80.

The fixture platform 10 includes a main body portion 11 and an abutting portion 15. The main body portion 11 is provided with a bearing plane 111. The abutting portion 15 is formed to protrude upward from the main body portion 11. The abutting portion 15 has a substantially L-shaped cross section. A card slot 16 is formed in the joint between the abutting portion 15 and the main body portion 11. The shoulder pressing plate 40 is located in the card slot 16. The shoulder platen 40 is movable along a guide post 45 that is substantially perpendicular to the direction of the load bearing plane 111. The shoulder platen 40 has a generally L-shaped cross section.

The backing plate 30 is a strip shaped plate. The backing plate 30 is fixed to the abutting portion 15 of the jig platform 10. The backing plate 30 is provided with a positioning plane 31. The backing plate 30 is mounted on the abutting portion 15. A mounting space 18 is defined between the mounting plate 30 and the bearing plane 111. The shoulder platen 40 extends into the fastening space 18.

Each positioning block 50 includes a positioning portion 51 and a mounting portion 53. The positioning portion 51 is a rectangular block. The positioning portion 51 includes two side walls 511. The plurality of positioning stops 50 abut against the positioning plane 31 of the backing plate 30. The plurality of positioning stops 50 are spaced apart. The distance between each two adjacent positioning stops 50 is equal. In the present embodiment, the distance between each two adjacent positioning stops 50 is approximately 40 mm. The mounting portions 53 are respectively fixed to the bearing plane 111. The two side walls 511 of each positioning portion 51 are perpendicular to the positioning plane 31, respectively.

The two guiding fixing blocks 70 are fixed on the bearing plane 111. Each of the guide bars 75 is connected to a guiding block 70 and a positioning block 50 on one side. The pressing plate 60 is slidably mounted to the two guiding bars 75. The pressing plate 60 includes a substrate 61 and a plurality of pressing blocks 65 protruding toward the positioning block 50. The rear end of each pressing block 65 can be slidably engaged with the substrate 61 by a spring.

The cylinder 80 is mounted on the jig platform 10, and the cylinder 80 is coupled to the pressing plate 60. The cylinder 80 can push the pressing plate 60 to move toward the backing plate 30.

The projection 105 of the insert 100 extends into the fastening space 18. The cylinder 80 is activated, and the cylinder 80 urges the pressing plate 60 to move toward the inlet 100. The pressing block 65 on the pressing plate 60 elastically presses the insert 100 to sandwich the insert 100 between the backing plate 30 and the pressing plate 60. At this time, the input 100 is fixed. In order to achieve a fixed reliability, the insert 100 can be further fixed by the shoulder platen 40. The shoulder pressing plate 40 presses the protrusion 105 of the inlet 100 downward in the fastening space 18 to press the inlet into the bearing plane 111.

During processing, the insert fixture and the fixed insert 100 are directly adsorbed on an electric discharge machine table, and the fixed insert 100 can be measured and discharged.

The fixed fixture can realize the batch and fast clamping, which improves the fixing efficiency.
