[0021] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail with reference to the drawings.

[0022] As Figure 1-2As shown in the figure, a workpiece fixing structure for a vacuum coating machine includes a placement plate 1, with insertion slots 11 symmetrically opened on both sides thereof. An insertion plate 21 is slidably arranged in the insertion slots 11. Chamfered clamping blocks 29 are symmetrically and slidably arranged on the insertion plate 21, and clamping slots 12 are symmetrically arranged on the insertion slots 11.

[0023] An unlocking plate 22 is slidably arranged on the insertion plate 21. At one end of the unlocking plate 22 located in the insertion slot 11, a spherical pushing member 28 for pushing the chamfered clamping block 29 to slide in the clamping slot 12 is provided, so that the insertion plate 21 is fixed in the insertion slot 11.

[0024] A clamping block 25 for fixing the workpiece is arranged on the insertion plate 21.

[0025] Specifically, when in use, first place the workpiece on the placement plate 1, then select a chuck 26 suitable for the workpiece specification. The chuck 26 is movably assembled on the clamping block 25. After installing the chuck 26 on the clamping block 25, insert the insertion plate 21 into the insertion slot 11. It should be noted that when inserting, always pull the unlocking plate 22 so that the unlocking plate 22 does not contact the chamfered clamping block 29. When the insertion plate 21 is inserted into the insertion slot 11, release the hand pulling the unlocking plate 22. At this time, the chamfered clamping block 29 moves into the clamping slot 12, fixing the insertion plate 21 in the insertion slot 11, and the chuck 26 fixes the workpiece.

[0026] In the above solution, the workpiece is placed on the placement plate 1. The workpiece is fixed on the placement plate 1 through the insertion slot 11 and the insertion plate 21. The unlocking and fixing of the workpiece are realized through the unlocking plate 22 in the insertion slot 11. The insertion plate 21 is fixed in the insertion slot 11 by the sliding of the chamfered clamping block 29 in the clamping slot 12, and the circular workpiece is fixed through the clamping block 25.

[0027] As a further embodiment provided by the present utility model, according to Figure 1 and Figure 2 As shown in the figure, a knocking plate 23 is fixedly arranged on the insertion plate 21, and the second end of the knocking plate 23 abuts against the clamping block 25.

[0028] Furthermore, the knocking plate 23 is U-shaped, and a plurality of elastic members 24 arranged in a linear array are provided in the middle. The other ends of the elastic members 24 abut against the clamping block 25.

[0029] Specifically, when the unlocking plate 22 is pulled, it will drive the knocking plate 23 to move. At this time, the elastic member 24 does not contact the clamping block 25, and the force for the clamping block 25 to abut against the workpiece disappears, for unlocking. When releasing the hand pulling the unlocking plate 22, it will knock on the clamping block 25, vibrating and falling off the dust and sundries attached to the insertion plate 21.

[0030] As a further embodiment provided by the present utility model, according toFigure 1 and Figure 2 As shown in Figure 2 , a plurality of reset members 27 arranged in an array are provided in the card slot 12. A plate member is provided at the other end of the reset member 27, and the plate member abuts against and pushes the chamfered block 29.

[0031] Furthermore, a notch 221 is formed on the unlocking plate 22.

[0032] Specifically, by pulling the notch 221 on the unlocking plate 22, the spherical pushing member 28 on the unlocking plate 22 is driven to move. At this time, the force for pushing the chamfered block 29 disappears. At this time, the plate member on the reset member 27 will push against the chamfered block 29, pushing the chamfered block 29 out of the card slot 12. At this time, the insertion plate 21 is unlocked in the insertion slot 11.

[0033] Working principle: During use, first place the workpiece on the placing plate 1, and then select a chuck 26 suitable for the workpiece specification. The chuck 26 is movably assembled on the clamping block 25. After the chuck 26 is installed on the clamping block 25, insert the insertion plate 21 into the insertion slot 11. It should be noted that when inserting, always pull the unlocking plate 22 so that the unlocking plate 22 does not contact the chamfered block 29. After the insertion plate 21 is inserted into the insertion slot 11, release the hand pulling the unlocking plate 22. At this time, the chamfered block 29 moves into the card slot 12, fixing the insertion plate 21 in the insertion slot 11.

[0034] When the unlocking plate 22 is pulled, it will drive the knocking plate 23 to move. At this time, the elastic member 24 does not contact the clamping block 25. At this time, the force for the clamping block 25 to push against the workpiece disappears, and unlocking is performed. When the hand pulling the unlocking plate 22 is released again, the clamping block 25 will be knocked, vibrating off the dust and debris attached to the insertion plate 21, driving the spherical pushing member 28 on the unlocking plate 22 to move. At this time, the force for pushing the chamfered block 29 disappears. At this time, the plate member on the reset member 27 will push against the chamfered block 29, pushing the chamfered block 29 out of the card slot 12. At this time, the insertion plate 21 is unlocked in the insertion slot 11.

[0035] Only some exemplary embodiments of the present invention are described above by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
