Description

Technical Field

[0001] This application relates to the technical field of clamping tools for circular inserts, and particularly to a clamping tool for circular inserts. Background Art

[0002] A circular insert is an insert with a circular cross-section. Circular inserts are commonly used for precise positioning and structural support in molds. During the production process, there are no obvious positioning features, which makes it difficult to ensure its axial and radial positions when positioning and fixing the circular insert in the mold, resulting in difficult processing.

[0003] For example, the utility model patent with the publication number CN207807147U discloses a fixing and clamping device for circular inserts in a processing mold, which includes a right-angle fixture and a support fixture. The right-angle fixture and the support fixture are connected by screws. The right-angle fixture is provided with clamping grooves at intervals. The support fixture includes two mutually perpendicular support panels, which are fixed by an inclined panel. A connecting rod is installed on the side wall of the inclined panel. A top ring is fixed at one end of the circular insert, and a flat groove is opened on the side wall of the top ring. The top ring is clamped in the clamping groove. When fixing the circular insert, the side wall of the circular insert abuts against the side wall of the right-angle fixture, and the end of the connecting rod abuts against the side wall of the circular insert. At this time, the circular insert is fixed under the action of the connecting rod and the support fixture.

[0004] The structure of the above right-angle fixture is fixed and can only clamp and fix circular inserts of one corresponding model, so there is room for improvement. Utility Model Content

[0005] In order to clamp circular inserts of different models, this application provides a clamping tool for circular inserts.

[0006] The clamping tool for circular inserts provided by this application adopts the following technical solutions:

[0007] A clamping tool for circular inserts includes a base. A connecting groove is opened on the side wall of the base. A clamping block is elastically connected to the inner wall of the base. The clamping block is located in the connecting groove. The side wall of the clamping block abuts against the flat groove of the circular insert. A V-shaped groove is opened on the side of the base away from the clamping block. The inner wall of the V-shaped groove abuts against the side wall of the circular insert. A clamping assembly for clamping the side wall of the circular insert is arranged on the base.

[0008] By adopting the above technical solutions, when fixing the circular insert, the side wall of the circular insert abuts against the inner wall of the V-shaped groove. At this time, the clamping assembly clamps the circular insert, the side wall of the clamping block abuts against the side wall of the circular insert, the flat groove of the top ring abuts against the side wall of the clamping block, and the clamping block slides away from the clamping assembly. This fixing method adapts to the diameters of different top rings, and the setting of the slidably connected clamping block facilitates the clamping and fixing of circular inserts of different models and sizes.

[0009] Optionally, a clamping groove is formed on the side wall of the base, and the side wall of the top ring abuts against the inner wall of the clamping groove.

[0010] By adopting the above technical solution, when fixing the round insert, the top ring is located in the clamping groove, improving the stability when clamping the round insert.

[0011] Optionally, the clamping assembly includes a clamping block slidably connected to the side wall of the base and a control block bolted to the base. The control block is used to control the clamping block to slide in the direction close to the round insert. The side of the clamping block away from the clamping block is inclined, and the side wall of the control block cooperates with the inclined surface of the clamping block.

[0012] By adopting the above technical solution, when clamping and fixing the round insert, tighten the bolt on the control block, the control block approaches the base, and under the action of the control block, the clamping block slides in the direction of the round insert to fix the position of the round insert. When removing the round insert, loosen the bolt on the control block, the control block moves away from the base, the side wall of the clamping block moves away from the side wall of the round insert, and the setting of the control block simplifies the process of clamping and fixing the round insert.

[0013] Optionally, a V-shaped groove is also formed on the side of the clamping block away from the control block, and the two V-shaped grooves cooperate, and the inner walls of the V-shaped grooves are in contact with the side wall of the round insert.

[0014] By adopting the above technical solution, when fixing the round insert, the side wall of the round insert abuts against the inner wall of the V-shaped groove, and the two V-shaped grooves work together to make the clamping of the round insert more stable.

[0015] Optionally, the clamping assembly further includes a bottom block fixed to the side wall of the base, and the side wall of the control block abuts against the side wall of the bottom block.

[0016] By adopting the above technical solution, under the action of the bottom block, the working state of the control block is more stable, reducing the sliding of the control block in the direction of the bottom block.

[0017] Optionally, a groove is formed on the side wall of the bottom block close to the base, and a locking tooth is formed on the side wall of the base, and the side wall of the locking tooth can abut against the inner wall of the groove.

[0018] By adopting the above technical solution, the groove of the bottom block fits with the locking tooth of the base, reducing the sliding of the bottom block in the sliding direction of the clamping block. By adjusting the position of the bottom block on the base, the moving displacement of the control block is changed, so as to facilitate the fixing of round inserts of different models.

[0019] Optionally, the side of the bottom block close to the control block is inclined, and the side wall of the control block abuts against the inclined surface of the bottom block.

[0020] By adopting the above technical solution, the side wall of the control block abuts against the side wall of the bottom block. When clamping the round insert, the control block slides on the side wall of the bottom block, and the inclined surface makes the sliding of the control block smoother.

[0021] Optionally, a through groove is formed on the side wall of the base, the through groove is formed in the sliding direction of the clamping block, a connecting block is installed in the through groove, a control bolt for adjusting the relative position of the control block on the base is installed on the side wall of the control block, and the control block is connected to the connecting block through the control bolt.

[0022] By adopting the above technical solution, when installing the clamping tooling, the connecting block is located in the through groove, and the position of the control block corresponds to that of the connecting block above the base. At this time, the control block and the connecting block are connected through the control bolt. When clamping the round insert, the control bolt is tightened, and the control block slides towards the clamping block under the action of the bottom block. The control block drives the clamping block to clamp the round insert, and the clamping effect of the clamping tooling is improved in this process.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When clamping and fixing the round insert, the side wall of the round insert abuts against the inner wall of the V-shaped groove, and the side wall of the top ring abuts against the side wall of the clamping block. The clamping assembly clamps the round insert. At this time, the clamping block slides towards the inner wall of the connecting groove. Under the action of the clamping block, the clamping tooling can clamp round inserts of different models, which is convenient for fixing round inserts of different models.

[0025] 2. Before clamping and fixing the round insert, the position of the bottom block on the base can be changed, the connecting block changes its position in the through groove, driving the position of the control block on the base to change. At this time, the clamping block slides under the action of the control block, making the clamping range of the clamping tooling larger. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following will Figure 1-2 be further described in detail with reference to the attached

[0030] An embodiment of the present application discloses a clamping tooling for a circular insert.

[0031] Referring to Figure 1 , a clamping tooling for a circular insert includes a base 1 and a clamping assembly 5 provided on the base 1. The clamping assembly 5 includes a clamping block 51 slidably connected to the side wall of the base 1, a control block 52 abutted against the side wall of the clamping block 51, and a bottom block 53 fixed to the side wall of the base 1. The sides of the clamping block 51 and the bottom block 53 close to the control block 52 are both inclined. The side wall of the control block 52 away from the clamping block 51 abuts against the side wall of the bottom block 53. The control block 52 is connected to the base 1 by bolts. When clamping the circular insert, the control block 52 approaches the base 1. Under the action of the control block 52, the clamping block 51 clamps the circular insert. The staff can realize the clamping of the circular insert only through the control block 52, which simplifies the operation process and facilitates the work of the staff.

[0032] V-shaped grooves 4 are provided on the side walls of the base 1 and the clamping block 51. The two V-shaped grooves 4 are arranged oppositely. A groove 7 is provided on the side wall of the bottom block 53. A locking tooth 8 is fixed to the side wall of the base 1. The inner wall of the locking tooth 8 fits with the inner wall of the groove 7. Before clamping the circular insert, the position of the bottom block 53 on the base 1 is adjusted. Under the action of the groove 7, the bottom block 53 is fixed in the sliding direction of the clamping block 51. When clamping the circular insert, the side wall of the circular insert abuts against the inner wall of the V-shaped groove 4, so that the position of the circular insert is fixed, improving the clamping effect of the clamping tooling.

[0033] In the embodiment of the present application, the clamping block 3 is connected to the base 1 by a central spring 11. One end of the central spring 11 is fixed to the side wall of the clamping block 3 away from the clamping block 51, and the other end of the central spring 11 is fixed to the inner wall of the base 1. The side wall of the clamping block 3 can abut against the flat groove of the top ring. A clamping groove 6 is provided on the side wall of the base 1. The side wall of the top ring abuts against the inner wall of the clamping groove 6. When clamping the circular insert, the side wall of the top ring abuts against the clamping block 3. Under the clamping action of the clamping block 3 and the clamping groove 6, the relative position of the top ring is fixed, improving the stability of the circular insert. At the same time, circular inserts of different models can be clamped, expanding the clamping range of the clamping tooling.

[0034] Referring to Figure 2 , a connecting groove 2 and a through groove 9 are further provided on the base 1. A control bolt 12 is installed on the side wall of the control block 52. The clamping block 3 is located in the connecting groove 2. A connecting block 10 is arranged in the through groove 9. Before clamping the circular insert, the connecting block 10 is connected to the control block 52 by the control bolt 12, and the clamping block 3 is connected to the base 1 by the central spring 11. When clamping the circular insert, the control bolt 12 is tightened. The side wall of the control block 52 slides on the inclined surface of the bottom block 53. Under the action of the control block 52, the connecting block 10 slides in the through groove 9, and the clamping block 51 clamps the circular insert. This process improves the clamping effect of the clamping tooling.

[0035] The implementation principle of the clamping tool for the circular insert in the embodiment of the present application is as follows: When clamping the circular insert, the flat groove of the top ring abuts against the side wall of the clamping block 3, the side wall of the top ring abuts against the inner wall of the clamping groove 6, and the side wall of the circular insert abuts against the inner wall of the V-shaped groove 4 on the base 1. At this time, the operator tightens the bolt of the control block 52, and the control block 52 drives the clamping block 51 to slide. The inner wall of the V-shaped groove 4 on the side wall of the clamping block 51 abuts against the side wall of the circular insert, and the top ring compresses the clamping block 3. The inner walls of the two V-shaped grooves 4 both abut against the side wall of the circular insert. During this process, the clamping tool can clamp circular inserts of different models, improving the working range of the clamping tool.
