Detailed Embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] It should be noted that when a component is referred to as being "mounted on" another component, it can be directly mounted on the other component or there may also be an intermediate component. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. When a component is considered to be "fixed to" another component, it can be directly fixed to the other component or there may be an intermediate component at the same time.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this utility model belongs. The terms used herein in the description of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0028] Such as Figure 1 AndFigure 2 and Figure 3 As shown in Figure 3 , the automatic cyclic ascending clamping fixture for profiles includes a frame 1, and also includes a profile positioning member, a clamping member, and a lifting mechanism. The above-mentioned positioning member is located inside the frame 1 and the lifting mechanism is located between the positioning member and the frame 1. Under the action of the lifting mechanism, the positioning member can move up and down horizontally. The clamping member is connected to the upper part of the frame 1 and the clamping member is located directly above the positioning member. When the lower end of the profile is connected to the positioning member, the upper end of the profile is located at the clamping member.

[0029] The lower end of the profile to be processed is connected to the positioning member, and the upper part of the profile is clamped by the clamping member. Such a structure can stably position the profile in this fixture, and the CNC machining device performs corresponding cutting machining at the upper part of the frame, thereby completing the corresponding machining operation.

[0030] After the machining is completed, the clamping member is loosened, and under the action of the lifting mechanism, the positioning member moves up smoothly by a set distance. After the above operation is completed, the lifting mechanism stops, and the clamping member clamps the profile again, so that the upper end of the profile can be subjected to corresponding machining.

[0031] During this machining operation, after the upper end of the profile is machined and formed, it is cut off to obtain a semi-finished product of a watch case. After completing the above operation, the lifting mechanism makes the profile continue to move up, which can ensure that there is always a profile with a fixed position at the upper part of the frame, facilitating batch operation.

[0032] The lifting mechanism includes a guide rod 2, a toothed rod 3, a positioning driving member, and a lifting driving member. The above-mentioned guide rod 2 is vertically fixed to the frame 1, the above-mentioned positioning member is horizontally arranged and the end of the positioning member is connected to the guide rod 2. The above-mentioned positioning driving member and the lifting driving member are both connected to the positioning member. The positioning driving member can abut against the toothed rod 3 and make the positioning member and the toothed rod 3 be positioned and connected. The lifting driving member can be embedded in the tooth 3a of the toothed rod 3.

[0033] The positioning driving member is used to position and connect the positioning member to the guide rod 2, and the lifting driving member is used to provide power. Under the action of this power, the positioning member can move up by a set distance relative to the toothed rod 3.

[0034] Of course, the positioning driving member and the lifting driving member operate alternately. When the positioning driving member positions and connects the positioning member to the toothed rod 3, the lifting driving member is in the retracted state. When the lifting driving member positions and connects the positioning member to the toothed rod 3, the positioning driving member is in the retracted state.

[0035] The lower end of the toothed rod 3 is fixedly connected to the lower part of the frame 1, the upper end of the toothed rod 3 is fixedly connected to the upper part of the frame 1, and the side of the toothed rod 3 has a number of uniformly distributed teeth 3a. A number of teeth 3a form an engagement connection part on the side of the toothed rod 3. One side of the tooth 3a is a locking surface 3a1 perpendicular to the toothed rod, and the other side of the tooth 3a is an inclined transition surface 3a2.

[0036] Such a structure can prevent the reverse movement of the rack 3.

[0037] As Figure 1 and Figure 4 shown, the positioning driving member includes a cylinder and a locking tongue 4 fixedly connected to the piston rod of the cylinder, and the lifting driving member includes a cylinder and a locking tongue 5 fixedly connected to the piston rod of the cylinder. The above-mentioned locking tongue 4 is located at the side of the meshing connection part, the above-mentioned locking tongue 5 is opposite to the meshing connection part, and both the above-mentioned locking tongue 4 and the locking tongue 5 can be embedded between two adjacent teeth 3a.

[0038] When the locking tongue 4 is embedded between two adjacent teeth 3a, the locking tongue 5 disengages from the meshing connection part. When the locking tongue 5 is embedded between two adjacent teeth 3a, the locking tongue 4 disengages from the meshing connection part.

[0039] The number of the positioning driving members is two, and the two positioning driving members are symmetrically distributed on both sides of the rack 3.

[0040] The setting of the two positioning driving members can further improve the positioning stability between the positioning member and the rack 3.

[0041] The positioning member includes a base plate 6, positioning blocks 7 and a connecting plate 8. The above-mentioned connecting plate 8 is connected to the guide rod 2. The above-mentioned base plate 6 is arranged horizontally and the end of the base plate 6 is fixedly connected to the connecting plate 8. The number of the above-mentioned positioning blocks 7 is several, and several positioning blocks 7 are fixedly connected to the upper part of the base plate 6. The number of the clamping members is the same as that of the positioning blocks 7 and they are arranged in one-to-one correspondence.

[0042] The contact area between the connecting plate 8 and the guide rod 2 is relatively large, which can ensure the connection stability between the positioning member and the guide rod 2.

[0043] At the same time, the plate-shaped base plate 6 provides sufficient positions for the connection of the positioning blocks 7.

[0044] Of course, in order to ensure the strength, a reinforcing rib can be provided between the base plate 6 and the connecting plate 8.

[0045] The clamping member includes a fixing plate 9, a movable plate 10 and a fastening driving member 11. The above-mentioned fixing plate 9 is fixedly connected to the upper part of the frame 1. The above-mentioned movable plate 10 is movably connected to the upper part of the frame 1. The above-mentioned fastening driving member 11 is fixedly connected to the frame 1 and the fastening driving member 11 is connected to the movable plate 10. The fastening driving member 11 can drive the movable plate 10 to move back and forth relative to the fixing plate 9.

[0046] The number of the fixing plates 9 is one, and the number of the movable plates 10 is multiple, which can effectively simplify the structure of the whole clamping member.

[0047] In this embodiment, one side of the fixed plate 9 has a number of movable plates 10, and a clamping unit capable of positioning a plurality of profiles is formed between one side of the fixed plate 9 and the number of movable plates 10. The number of the clamping units is two, and the two clamping units are symmetrically distributed on both sides of the fixed plate 9.

[0048] It can be seen that this effectively simplifies the structure of the clamping member.

[0049] A guide block 12 is fixedly connected to the frame 1. The above-mentioned movable plate 10 is embedded in the guide block 12. The above-mentioned fastening drive member 11 is a cylinder, and an inclined push rod 13 is fixedly connected to the piston rod of the cylinder. The above-mentioned movable plate 10 has a push hole 10a matching the push rod 13, and the above-mentioned push rod 13 is embedded in the push hole 10a.

[0050] The movable plate 10 is limited between two adjacent guide blocks 12 on the left and right. A number of guide blocks 12 are evenly arranged along the length direction of the fixed plate 9. Such a structure can position a plurality of adjacent movable plates 10 in sequence.

[0051] A limiting column 14 is fixedly connected to the lower part of the frame 1, and the above-mentioned substrate 6 is located above the limiting column 14.

[0052] The limiting column 14 is made of a flexible material. The moving stroke of the positioning member can be limited through the limiting column 14, and finally the stability is improved.

[0053] A rodless cylinder 15 is also vertically fixedly connected to the frame 1. A protruding support edge 15a is provided on the slider of the rodless cylinder 15, and the above-mentioned support edge 15a can abut against the lower part of the substrate 6.

[0054] During the operation of the rodless cylinder, the support edge 15a thereon moves along with it. It can be seen that one end of the substrate is connected to the guide rod, and the support edge 15a can support the other end of the substrate, and finally ensure that the positioning member can move stably.

[0055] Since the lifting mechanism of this automatic circulating ascending clamping fixture for profiles can enable the positioning member to stably achieve the set feed each time, therefore, the workpiece located on the positioning member can smoothly achieve the feed, and its feeding operation is stable.

[0056] At the same time, the upper part of the workpiece is clamped by the clamping member, and the workpiece can be stably positioned during the processing operation, ensuring the stability of the processing operation.

[0057] In addition, a plurality of corresponding positioning members and clamping members also effectively improve the operation efficiency and have high practical value.

[0058] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity in description, not all possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.

[0059] Those of ordinary skill in the art should recognize that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. As long as appropriate changes and variations made to the above embodiments are within the spirit of the present invention, they fall within the scope of protection required by the present invention.
