[0025] 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.
[0026] The following is in conjunction with the appendix Figures 1 to 7 The specific embodiments of this utility model will be described in further detail.
[0027] It should be noted that this utility model is used in conjunction with a fixture for processing polymer plastics, and the relevant structure of the fixture for processing polymer plastics is as follows;
[0028] A fixture for processing polymer plastics includes a positioning plate 1. 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 provided 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. 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.
[0029] 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.
[0030] Furthermore, by Figures 5 to 7 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.
[0031] 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.
[0032] Furthermore, by Figures 5 to 7 As 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.
[0033] 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.
[0034] Furthermore, by Figures 5 to 7 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.
[0035] Furthermore, by Figures 5 to 7 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.
[0036] Furthermore, by Figures 5 to 7 As shown, in order to make the clamping force 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.
[0037] Furthermore, by Figures 5 to 7 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.
[0038] 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.
[0039] The following is in conjunction with the appendix Figures 1 to 4 The specific embodiments of this utility model will be described in further detail.
[0040] Depend on Figures 1 to 4 As shown, this utility model includes a fixing block 21. In order to position the workpiece clamping position, the fixing block 21 is provided with a plurality of positioning rods 22 in the middle. A plurality of first connecting components 23 are provided between the fixing block 21 and the positioning rods 22. Each positioning rod 22 is detachably connected to the fixing block 21 through a corresponding first connecting component 23. A magnetic plate 24 that can move back and forth relative to the fixing block 21 is provided on the front side of the fixing block 21, which can adapt to workpieces of different processing types. The magnetic plate 24 has magnetic force and can attract each other with the clamping plate 3. An adjustment component 25 for adjusting the position of the magnetic plate 24 is provided inside the fixing block 21.
[0041] In use, the positioning rod 22 can be fixed to the fixing block 21 by the first connecting component 23. Then, the front and rear positions of the magnetic plate 24 relative to the fixing block 21 can be adjusted by the adjusting component 25, so that the magnetic plate 24 and the clamping plate 3 can be magnetically attracted together. After the engagement, the left and right sides of each positioning rod 22 can limit the position of the workpiece clamping, thereby positioning the processing position of the workpiece. After the workpiece is clamped by the clamping block 7, the magnetic plate 24 and the fixing block 21 can be removed, thus completing the positioning and clamping of the workpiece.
[0042] Furthermore, by Figures 1 to 4 As shown, in order to replace positioning rods 22 of different lengths, the fixing block 21 has multiple transverse holes 26 that are adapted to the positioning rods 22. The first connecting assembly 23 includes a first bolt 27 and a rubber block 28. Each transverse hole 26 has a threaded hole 29 on its rear side. The first bolt 27 is threadedly connected to the threaded hole 29. The rubber block 28 is fixedly connected to the front side of the first bolt 27. The front side of the rubber block 28 abuts against the positioning rod 22.
[0043] In use, the positioning rod 22 can be fixed relative to the fixing block 21 by the contact between the first bolt 27 and the rubber block 28 on the rear side of the positioning rod 22 through pressure.
[0044] Furthermore, by Figures 1 to 4 As shown, in order to make the adjustment of the magnetic plate 24 smoother, the front side of the fixing block 21 is provided with a plurality of first sliding grooves 30, and a first sliding rod 31 is slidably connected inside each first sliding groove 30.
[0045] Furthermore, by Figures 1 to 4 As shown, in order to facilitate operation by the staff, the adjustment assembly 25 includes a power rod 32 and an adjustment rod 33. Multiple connecting rods 34 are provided between the power rod 32 and the adjustment rod 33. Both ends of each connecting rod 34 are fixedly connected to the power rod 32 and the adjustment rod 33 respectively.
[0046] When in use, rotating the power rod 32 can drive the adjusting rod 33 to make a circular motion around the power rod 32 via the connecting rod 34.
[0047] Furthermore, by Figures 1 to 4 As shown, each first sliding rod 31 has an adjustment groove 35 in the middle, and each adjustment groove 35 cooperates with the adjustment rod 33;
[0048] In use, when the adjusting rod 33 moves in a circular motion around the power rod 32, the first sliding rod 31 can move back and forth through the adjusting groove 35 because the adjusting rod 33 abuts against the inner wall of the adjusting groove 35.
[0049] Furthermore, by Figures 1 to 4 As shown, in order to lock the extension and retraction length of the magnetic plate 24, a worm gear 36 is fixedly connected to the middle of the power rod 32, a worm 37 is engaged at the rear side of the worm gear 36, and an operating rod 38 is coaxially fixedly connected to the right side of the worm 37; a stabilizing block 39 is fixedly connected to the bottom of the fixing block 21.
[0050] In use, the worm gear 37 can be rotated to drive the worm wheel 36 to rotate, which in turn drives the power rod 32 to rotate. The stabilizing block 39 is used to increase the stability of the bottom of the fixed block 21.
[0051] When using this utility model, it should first be noted that two of these devices need to be set on the front and rear sides of the clamping block 7. Then, the positioning rod 22 can be fixed on the fixing block 21 by the first connecting component 23. After adjusting the front and rear position of the magnetic plate 24 relative to the fixing block 21 by the adjusting component 25, the magnetic plate 24 and the clamping plate 3 can be magnetically attracted together. After the engagement, the left and right sides of each positioning rod 22 can limit the position of the workpiece clamping, thereby positioning the processing position of the workpiece. After the workpiece is clamped by the clamping block 7, the magnetic plate 24 and the fixing block 21 can be removed, thus completing the positioning and clamping of the workpiece.
[0052] This utility model has a novel structure, ingenious design, and simple and convenient operation. Through this design, it effectively realizes the function of positioning the workpiece clamping position, adds the function of being able to replace positioning rods 22 of different lengths, makes the adjustment of the magnetic plate 24 smoother, and adds the function of locking the extension and retraction length of the magnetic plate 24.
[0053] 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.
