[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] The following is in conjunction with the appendix Figures 1 to 3 The specific embodiments of this utility model will be described in further detail.

[0023] Depend on Figures 1 to 3 As shown, this utility model includes a positioning plate 1. In order to facilitate the clamping and processing of multiple workpieces, a stabilizing plate 2 is detachably connected to the upper side of the positioning plate 1, and a clamping plate 3 is detachably connected to the upper side of the stabilizing plate 2. Two second sliding grooves 4 are opened on the left and right sides of the clamping plate 3. Each second sliding groove 4 is provided with a power block 5 that can move left and right inside. The power block 5 divides each second sliding groove 4 into two clamping areas 6 for clamping workpieces. Each clamping area 6 is provided with a clamping block 7 that can move up and down with the movement of the power block 5.

[0024] In use, the workpiece is placed inside the corresponding clamping area 6. When the power block 5 is moved, the power block 5 will drive the corresponding clamping block 7 to move up and down, thereby reducing the longitudinal height of the corresponding clamping area 6. The workpiece is clamped by the upper and lower side walls of the clamping area 6, that is, by the inner side wall of the second sliding groove 4 and the side wall of the clamping block 7. After clamping, the positioning plate 1 can be matched with the machining center to perform the milling operation of the workpiece.

[0025] Furthermore, by Figures 1 to 3 As shown, in order to make the device modular and facilitate the replacement and updating of components, the positioning plate 1 has multiple first positioning holes 8 inside. The lower side of the stabilizing plate 2 is fixedly connected with a first positioning sleeve 9 corresponding to the first positioning hole 8. The lower side of each first positioning sleeve 9 is threadedly connected with a first positioning screw 10. The lower side of each first positioning screw 10 is fixedly connected with a first positioning block 11. The upper side of the first positioning block 11 abuts against the lower side of the positioning plate 1.

[0026] In use, by rotating the first positioning screw 10, the positioning plate 1 and the stabilizing plate 2 can be pressed and fixed together by the threaded connection between the first positioning screw 10 and the first positioning sleeve 9. The first positioning block 11 is used to connect the positioning plate 1 to the machining center.

[0027] Furthermore, by Figures 1 to 3As shown, in order to facilitate the replacement of the clamping plate 3, two countersunk positioning holes 12 are provided on the lower side of the positioning plate 1. Each countersunk positioning hole 12 is provided with a second positioning screw 13. Two second positioning holes 14 are provided on the lower side of the clamping plate 3. The middle part of the second positioning screw 13 passes through the stabilizing plate 2 and is threadedly connected to the corresponding second positioning hole 14.

[0028] When it is necessary to replace the clamping plate 3, the second positioning screw 13 can be removed. At this time, the clamping plate 3 will contact and cooperate with the positioning plate 1, and can be replaced and repaired.

[0029] Furthermore, by Figures 1 to 3 As shown, in order to achieve a better clamping effect, each second sliding groove 4 has a first clamping groove 15 inside, and each clamping block 7 has a first clamping slider 16 fixedly connected to the side of the first clamping groove 15. Each first clamping slider 16 is slidably connected to the corresponding first clamping groove 15.

[0030] Furthermore, by Figures 1 to 3 As shown, in order to facilitate the operation of the staff, a second clamping slider 17 is fixedly connected to the upper and lower sides of each power block 5. A second clamping groove 18 is opened on the side of each clamping block 7 near the power block 5. Each second clamping slider 17 is slidably connected to the corresponding second clamping groove 18.

[0031] Furthermore, by Figures 1 to 3 As shown, in order to make the clamping forces on the workpieces on the upper and lower sides of the power block 5 similar, each power block 5 is a quadrangular frustum, and the upper and lower inclined surfaces of the power block 5 are slidably connected to the corresponding clamping block 7.

[0032] Furthermore, by Figures 1 to 3 As shown, in order to facilitate the replacement of workpieces, each power block 5 is threaded with a power screw 19 in the middle, and the side of each power screw 19 near the clamping plate 3 is rotatably connected to the clamping plate 3; each clamping area 6 is provided with a contact block 20 on the upper and lower sides.

[0033] When in use, rotating the power screw 19 will cause the power block 5 to move left and right due to the threaded connection between the power screw 19 and the power block 5. Since the power block 5 is a quadrangular frustum, there is an angle between the first clamping groove 15 and the second clamping groove 18. When the power block 5 moves left and right, it will cause the clamping block 7 to move up and down, which will adjust the longitudinal height of the clamping area 6. When the height decreases, the workpiece will be clamped. This will also make the clamping force on the two workpieces on the upper and lower sides of each power block 5 similar, reducing the probability of the polymer plastic workpiece being damaged due to excessive pressure.

[0034] When using this utility model, the workpiece is first placed inside the corresponding clamping area 6. When the power block 5 is moved, the power block 5 will drive the corresponding clamping block 7 to move up and down, thereby reducing the longitudinal height of the corresponding clamping area 6. The workpiece is clamped by the upper and lower side walls of the clamping area 6, that is, by the inner side wall of the second sliding groove 4 and the clamping block 7. After clamping, the positioning plate 1 can be matched with the machining center to perform the milling operation of the workpiece.

[0035] This utility model has a novel structure, ingenious design, and simple and convenient operation. This design effectively facilitates the clamping and processing of multiple workpieces, enables modular design of the device, facilitates the replacement and updating of components, makes it easy to replace the clamping plate 3, achieves better clamping effect, facilitates operation by the operator, and makes the clamping force on the workpieces on the upper and lower sides of the power block 5 similar, reducing the defect rate.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
