Description

Technical Field

[0001] The utility model relates to the field of clamping and bending tooling, in particular to a clamping and bending tooling used for a T-shaped locking piece. Background Art

[0002] In the current separate turbine disc and turbine blade, a T-shaped locking plate with two raised ends is generally used to fix the turbine blade on the turbine disc. When in use, one end of the locking plate needs to be warped in advance and placed in the tenon groove of the turbine disc. After the turbine blade is placed in the tenon groove, the other end of the T-shaped locking plate is warped to clamp the turbine blade. Therefore, the warping of the T-shaped locking plate directly affects the fixation of the turbine blade.

[0003] In the existing scheme, there are two ways to achieve pre-bending of the T-shaped locking plate. One is that the manufacturer uses special equipment to pre-bend, and the other is to manually use a clamp to clamp each locking plate and then use a hammer to bend one end of the T-shaped locking plate.

[0004] However, both methods have the following shortcomings:

[0005] (1) For R&D work, since there is often no need to purchase large quantities of lock pieces, when the purchase volume is less than 1,000 pieces, manufacturers are usually unwilling to invest in specialized equipment for pre-bending processing. This makes the processing of small batches of lock pieces relatively difficult;

[0006] (2) Each aircraft engine requires a large number of turbine lock plates. If they are bent one by one manually using a clamp and a hammer, it will not only be inefficient but also time-consuming, which obviously cannot meet the high-efficiency requirements of modern aircraft engine production. At the same time, when manually using a hammer to perform the warping operation, the force cannot be well controlled. Excessive knocking force or a slight deviation in the knocking position may cause indentations at the bend of the lock plate, which not only affects the aesthetics of the lock plate, but may also increase the risk of the lock plate breaking during use, thereby posing a potential threat to the overall safety of the aircraft engine. In addition, it is difficult for manual operation to ensure that the state of the lock plate is consistent each time it is bent. This inconsistency may lead to differences in the fixing effect of the turbine blade, thereby affecting the performance and stability of the engine. Utility Model Content

[0007] The purpose of the utility model is to provide a clamping and bending tool for T-shaped locking plates, which realizes efficient and stable pre-bending preparation of small batches of T-shaped locking plates, not only shortens the total time required for preparation, but also ensures that the bending state of each part is consistent, effectively solving the problems in the prior art.

[0008] The above-mentioned optimized structure of the utility model is realized through the following technical scheme: a clamping and bending tool for T-shaped locking plates, comprising a base plate, the base plate is provided with at least two placement grooves, the placement grooves pass through a side surface of the base plate, a cover plate is hinged on the base plate, the cover plate is provided with a molding groove on a side surface close to the placement grooves, the molding groove passes through the bottom wall of the cover plate, the base plate is provided with a side cover plate on a side close to the placement grooves, and the side cover plate is hinged to the base plate.

[0009] In some embodiments, a fixing hole is provided on a side of the bottom plate away from the placement groove, a fixing shaft is coaxially provided with the fixing hole, and the cover plate is sleeved on the fixing shaft.

[0010] In some embodiments, the fixing shaft is disposed on a side of the bottom plate away from the placement slot.

[0011] In some embodiments, a stop plate is provided on one side of the bottom plate close to the placement groove, and a stop groove is provided on the cover plate corresponding to the position of the stop plate, and the stop plate is plugged into and matched with the stop groove.

[0012] In some embodiments, the connection between the molding groove and the bottom wall of the cover plate is rounded.

[0013] In some embodiments, two rotating blocks are symmetrically provided at the bottom of a side surface of the bottom plate close to the placement groove, and two rotating pins are provided at both ends of the side cover plate, and the two rotating pins are respectively connected to the two rotating blocks.

[0014] In some embodiments, a handle is provided in the middle of the side cover.

[0015] In some embodiments, the bottom plate, the cover plate, and the side cover plate are all made of aluminum alloy plates.

[0016] In summary, the utility model has the following beneficial effects:

[0017] This bending fixture for T-locking pieces fixes multiple T-locking pieces on the bottom plate by rotating between the bottom plate and the cover plate, and pre-bends multiple T-locking pieces at the same time by rotating the side cover plate, thereby realizing efficient and stable pre-bending preparation of small batches of T-locking pieces, shortening the total preparation time, and providing a molding groove on the side of the cover plate so that the T-locking piece is placed in the molding groove after being bent, thereby ensuring the consistency of the bending state of each part.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] refer to Figure 1-4 , a clamping and bending tool for a T-shaped locking piece, comprising a bottom plate 1, a cover plate 2, and a side cover plate 3. The bottom plate 1, the cover plate 2, and the side cover plate 3 can all be square plates. The bottom plate 1 is provided with at least two placement grooves 11. The plurality of placement grooves 11 can realize the simultaneous pre-bending of multiple T-shaped locking pieces. The placement groove 11 runs through a side surface of the bottom plate 1. The shape of the placement groove 11 is adapted to the shape of one end of the T-shaped locking piece, which is convenient for fixing the T-shaped locking piece on the placement groove 11, and at the same time, the part of the T-shaped locking piece that does not need to be bent is completely protected. The bottom plate 1 is hinged with the cover plate 2. Specifically, a fixing hole 12 can be provided on the side of the bottom plate 1 away from the placement groove 11. The fixing hole 12 is coaxially provided with a fixing shaft 4. The fixing shaft 4 is sleeved with the cover plate 2, which can make the cover plate 2 rotate on the base 1, thereby realizing the hinge between the bottom plate 1 and the cover plate 2, and realizing the opening and closing of the cover plate 2 to the placement groove 11, which is convenient for the T-shaped locking piece. The cover plate 2 is provided with a forming groove 21 on one side close to the placement groove 11. The forming groove 21 runs through the bottom wall of the cover plate 2 and is connected to the placement groove 11 when the cover plate 2 closes the placement groove 11. The forming groove 21 is adapted to the shape of the other end of the T-shaped locking piece, so that when the T-shaped locking piece is pre-bent, the other end of the T-shaped locking piece is completely fitted with the forming groove 21, thereby ensuring the consistency of the pre-bent state of the T-shaped locking piece; a side cover plate 3 is provided on the side close to the placement groove 11 of the bottom plate 1, and the side cover plate 3 is hinged to the bottom plate 1. Two rotating blocks 14 are symmetrically provided at the bottom of the side of the bottom plate 1 close to the placement groove 11. Two rotating pins 31 are provided at both ends of the side cover plate 3. The two rotating pins 31 are respectively axially connected to the two rotating blocks 14, so that the side cover plate 3 can be rotated relative to the bottom plate 1, squeezing the T-shaped locking piece protruding from one end of the bottom plate 1, so that the T-shaped locking piece is bent and placed in the forming groove 21, thereby realizing the pre-bending of the T-shaped locking piece.

[0025] In some embodiments, the fixed axis 4 is disposed on the side of the base plate 1 away from the placement slot 11, and can be disposed at a corner of the base plate 1 away from the placement slot 11. It can be rotated at a small angle to fully open the placement slot, which is convenient for taking and placing the T-shaped locking piece.

[0026] In some embodiments, a stop plate 13 is provided on one side of the base plate 1 close to the placement groove 11, and a stop groove 22 is provided on the cover plate 2 corresponding to the stop plate 13. The stop plate 13 and the stop groove 22 are plugged into each other to realize the positioning of the cover plate 2 when it rotates. When the T-shaped locking plate is pre-bent multiple times, the base plate 1 and the cover plate 2 are always in the same position, thereby avoiding the influence on the consistency of the pre-bending state when the relative positions of the base plate 1 and the cover plate 2 are different when the T-shaped locking plate is pre-bent.

[0027] In some embodiments, the connection between the forming groove 21 and the bottom wall of the cover plate 2 is rounded, which can reduce the pressure on the T-shaped locking piece, avoid the generation of indentations, and reduce the risk of the T-shaped locking piece breaking during use.

[0028] In some embodiments, a handle 5 is provided in the middle of the side cover plate 3 to facilitate manual rotation of the side cover plate 3 .

[0029] In some embodiments, the bottom plate 1, the cover plate 2 and the side cover plate 3 are all aluminum alloy plates, which can increase the service life of the clamp bending tooling. At the same time, the lightweight aluminum alloy plates facilitate the control of force during the pre-bending process.

[0030] The specific working principle is as follows:

[0031] When in use, multiple T-shaped locking pieces are placed in multiple placement grooves 11 of the bottom plate 1, and then the cover plate 2 is rotated to make the stop plate 13 plug and match with the stop groove 22, so that the cover plate 2 closes the placement groove 11, and the T-shaped locking piece is fixed on the bottom plate 1, and the molding groove 21 on the cover plate 2 is aligned with the position where the locking piece needs to be bent. Then, the side cover plate 3 is flipped and covered by the handle 5, so that the side cover plate 3 fits with the cover plate 2 and the bottom plate 1. During the fitting process, after the side cover plate 3 contacts the T-shaped locking piece, the side cover plate 3 is rotated slowly with uniform force to avoid the T-shaped locking piece being bent quickly, which may cause creases at the bending point of the T-shaped locking piece, reduce the strength of the locking piece, and complete the simultaneous bending of multiple T-shaped locking pieces.

[0032] At this time, the outer wall of the side cover plate 3 can be gently knocked by an external force (such as a hammer) to make the T-shaped locking piece fit completely with the forming groove 21 to improve the consistency of the bending state.

[0033] When the T-shaped locking piece is bent into a desired shape, the side cover plate 3 is loosened, the cover plate 2 is rotated, the placement slot 11 is opened, and the bent T-shaped locking piece can be taken out.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
