Description

Technical Field

[0001] The present application relates to the field of auxiliary positioning devices for heat treatment technology, and in particular to a load couple quick fixing device. Background Art

[0002] The material of large aircraft engine parts is usually titanium alloy, which is generally machined from cast blanks. Such large parts used in aerospace have very strict requirements on the accuracy of structure and surface. If a part that has been finely machined to the design size has local defects on the surface, it is easy to cause irreparable losses if it is not handled in time and continues to be used in aircraft engines; however, such parts that only have local defects on the surface but are finely machined to the design size will appear from time to time in production practice. Once such parts are directly discarded, it will cause economic losses of hundreds of thousands to millions.

[0003] The usual practice is to repair the defective parts by welding and take local heat treatment to reduce the thermal deformation of the parts. The main control parameters of the heat treatment process are heating temperature and holding time.

[0004] The current method for accurately controlling the heating time of parts is: before the product enters the heat treatment furnace, a load couple (i.e., "load thermocouple") is tied to the product through a nickel-chromium wire, so that the load couple enters the heat treatment furnace with the product to record the temperature of the product. Since the load thermocouple is connected to a recording instrument, when the recording instrument reaches the process set temperature, it starts calculating the holding time, thereby accurately controlling the holding time of the heat treatment of the parts to reduce the possibility of thermal deformation of the parts.

[0005] In the above heat treatment, the load couple and the product are bound by tying nickel-chromium wire. Since the two ends of the nickel-chromium wire are relatively sharp, the staff need to manually twist and knot the two ends of the nickel-chromium wire until the load couple and the product are fixed. During the binding process, the operator is easily scratched by the tip of the nickel-chromium wire. In order to avoid injury, the operator needs to be careful with the binding operation, which increases the operation time and reduces the work efficiency of the heat treatment. Utility Model Content

[0006] In order to achieve rapid fixation of a load couple, the present application provides a load couple rapid fixation device.

[0007] The present application provides a load couple quick fixing device adopts the following technical solution:

[0008] A load couple quick fixing device comprises a fixed clamping plate and a movable clamping plate, wherein a limit piece is arranged on the side of the fixed clamping plate facing the movable clamping plate corresponding to the load couple and the product, and when the movable clamping plate moves in a direction close to the fixed clamping plate, the limit piece limits the product and the load couple between the fixed clamping plate and the movable clamping plate, and a fastener for fastening the product and the load couple is arranged between the fixed clamping plate and the movable clamping plate.

[0009] By adopting the above technical solution, the operator first places the fixed clamping plate against the bottom of the product, and limits the product and the load couple through the limiter. At this time, the movable clamping plate is taken and moved toward the fixed clamping plate until the movable clamping plate clamps the product and the load couple limited on the fixed clamping plate, and finally the load couple is fixed to the product through the fastener. This fixing device avoids the possibility of scratching the operator and can realize the rapid fixing of the load couple. This device is not only easy to use, but also can be used for repeated use, thereby reducing the waste of materials.

[0010] Optionally, the limiting members are a plurality of connecting rods disposed on the side of the fixed clamping plate facing the movable clamping plate, the movable clamping plate is provided with through holes for the connecting rods to pass through, the connecting rods correspond to the through holes one by one and are plug-fitted.

[0011] By adopting the above technical solution, the line segment of the product's support rod and load couple is limited between two adjacent connecting rods, and when the movable clamp plate approaches the fixed clamp plate, a through hole is formed through the connecting rod to form a clamping space between the movable clamp plate, the fixed clamp plate and the two connecting rods on both sides of the line segment of the product's support rod and load couple. The closer the movable clamp plate and the fixed clamp plate are to each other, the narrower the clamping space becomes, until the product's support rod and load couple line segment fit closely together. Reduce the interference of the load couple with the product entering the heat treatment furnace with the product on the product temperature recording data, and accurately control the heat preservation time of the parts heat treatment to reduce the possibility of thermal deformation of the parts.

[0012] Optionally, the fastener is a nut; the connecting rod includes a smooth rod and a threaded rod arranged at one end of the smooth rod, the end of the smooth rod away from the threaded rod is connected to the fixed clamping plate, the nut is sleeved on the threaded rod, and the nut is threadably matched with the threaded rod passing through the movable clamping plate.

[0013] By adopting the above technical solution, a nut is sleeved on the threaded rod of the connecting rod passing through the movable clamping plate, and the nut is rotated in the direction close to the movable clamping plate, and the movable clamping plate is pushed to move in the direction close to the fixed clamping plate, thereby reducing the clamping space until the support rod part of the product and the line segment of the load couple are tightly fitted together, and the nut cannot continue to rotate, thereby locking the position of the product and the load couple at this time.

[0014] Optionally, a clamping groove is opened on the movable clamping plate along the width direction of the movable clamping plate, the clamping groove is located between two through holes, the length direction of the clamping groove is parallel to the width direction of the movable clamping plate, and both ends of the clamping groove extend to the side wall of the movable clamping plate.

[0015] By adopting the above technical solution, since a clamping groove for a limited load couple is provided on the movable clamping plate along the width direction of the movable clamping plate, when the load couple is confined in the clamping groove, the possibility of displacement of the load couple when it is partially in contact with the product support rod can be reduced, thereby improving the accuracy of the load couple in recording the temperature of the product in the heat treatment furnace, thereby reducing the possibility of thermal deformation of the parts based on the calculated insulation time.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:

[0017] 1. The operator first places the fixed clamp against the bottom of the product, and limits the product and the load couple through the limiter. At this time, take the movable clamp and move it towards the fixed clamp until the movable clamp clamps the product and the load couple limited on the fixed clamp. Finally, the load couple and the product are fixed by fasteners. This fixing device avoids the possibility of scratching the operator and can realize the rapid fixing of the load couple. This device is not only easy to use, but also can be used repeatedly, thereby reducing material waste;

[0018] 2. The line segment of the product's support rod and load couple is limited to two adjacent connecting rods, and when the movable clamp plate approaches the fixed clamp plate, a through hole is drilled through the connecting rod to form a clamping space between the movable clamp plate, the fixed clamp plate and the two connecting rods on both sides of the line segment of the product's support rod and load couple. The closer the movable clamp plate and the fixed clamp plate are to each other, the narrower the clamping space becomes, until the product's support rod and load couple line segment fit tightly together. Reducing the interference of the load couple with the product entering the heat treatment furnace with the product on the product's temperature recording data can accurately control the insulation time of the heat treatment of the parts to reduce the possibility of thermal deformation of the parts;

[0019] 3. Use a nut to cover the threaded rod of the connecting rod that passes through the moving clamping plate. The nut rotates toward the moving clamping plate and pushes the moving clamping plate toward the fixed clamping plate, thereby reducing the clamping space until the support rod part of the product and the line segment of the load couple fit tightly together and the nut cannot continue to rotate, thereby locking the position of the product and the load couple.

[0024] The following is combined with Figure 1-2 This application is described in further detail.

[0025] The embodiment of the present application discloses a load couple quick fixing device.

[0026] Example 1

[0027] Reference Figure 1 A load couple quick fixing device includes a fixed clamping plate 1 and a movable clamping plate 2. The fixed clamping plate 1 and the movable clamping plate 2 in this embodiment have the same size, a length of 30 mm, a width of 5 mm, and are arranged parallel to each other. A limit member 3 is arranged on the side of the fixed clamping plate 1 facing the movable clamping plate 2 corresponding to the load couple and the product, and a fastener 4 is arranged between the fixed clamping plate 1 and the movable clamping plate 2 corresponding to the load couple and the product.

[0028] Reference Figure 1 The operator first places the fixed clamping plate 1 against the bottom of the product and limits the product and the load couple through the limiter 3. At this time, take the movable clamping plate 2 and move it towards the fixed clamping plate 1 until the movable clamping plate 2 clamps the product and the load couple limited on the fixed clamping plate 1, and finally fixes the load couple to the product through the fastener 4.

[0029] Reference Figure 1 A clamping groove 21 for plugging with a load couple is provided on one side of the movable clamping plate 2 facing the fixed clamping plate 1 along the width direction of the movable clamping plate 2. The clamping groove 21 is located between the two through holes 22 and both ends of the clamping groove 21 extend to the side wall of the movable clamping plate 2. The length direction of the clamping groove 21 is parallel to the width direction of the movable clamping plate 2.

[0030] Reference Figure 1 The limiting member 3 is a plurality of connecting rods arranged on the side of the fixed clamping plate 1 facing the movable clamping plate 2. In this embodiment, two connecting rods are taken as an example. The length of each connecting rod is 25 mm. The length directions of the two connecting rods are perpendicular to the side wall of the fixed clamping plate 1, and the rod ends of the two connecting rods are fixedly arranged on the fixed clamping plate 1.

[0031] Reference Figure 1A through hole 22 for the connecting rod to pass through is opened on the movable clamping plate 2 corresponding to each connecting rod. The connecting rod includes a smooth rod 31 and a threaded rod 32. The end of the smooth rod 31 away from the threaded rod 32 is fixedly arranged on the fixed clamping plate 1, and the end of the threaded rod 32 away from the smooth rod 31 slides through the through hole 22 along its own length direction. The fastener 4 in this embodiment is a nut, which is threadably mounted on the threaded rod 32 through the through hole 22 and extends out of the rod body of the movable clamping plate 2.

[0032] The implementation principle of a load couple quick fixing device in an embodiment of the present application is as follows: the operator first abuts the fixed clamping plate 1 against the bottom of the product, clamps the support rod part of the product between the two connecting rods, and then inserts the line segment of the load couple into the clamping groove 21, so that the movable clamping plate 2 and the fixed clamping plate 1 are spliced ​​by the plug-in cooperation of the connecting rod and the through hole 22. At this time, the product and the load couple are both confined in the clamping space formed by the movable clamping plate 2, the fixed clamping plate 1 and the two connecting rods located on both sides of the support rod part of the product and the line segment of the load couple, and the operator sets the nut on the threaded rod 32 through a threaded sleeve, and rotates the nut so that the nut abuts the movable clamping plate 2 and approaches the fixed clamping plate 1 until the product and the load couple are tightly fitted together, thereby completing the quick fixation between the load couple and the product.

[0033] Example 2

[0034] Reference Figure 2 The difference between this embodiment and embodiment 1 is that a fixing part 5 for assisting in clamping the load couple and the product is provided between the movable clamping plate 2 and the fixed clamping plate 1, and a connecting rope 6 made of high temperature resistant silicone rubber material is fixedly connected between the movable clamping plate 2 and the fixed clamping plate 1.

[0035] Reference Figure 2 The fixing member 5 includes a pillar 51, a limiting ball 52 and an elastic connecting member 53. The pillar 51 is integrally formed on the movable splint 2 and the fixed splint 1, and one pillar 51 is provided on both sides adjacent to the surface where the connecting rod is located on the fixed splint 1, and one pillar 51 is provided on both sides adjacent to the surface where the clamping groove 21 is located on the movable splint 2. A limiting ball 52 is provided corresponding to each pillar 51, and is integrally formed at the end of the pillar 51 away from the connection. The elastic connecting member 53 in this embodiment is a rubber strip made of silicone rubber. Notches are cut at both ends of the rubber strip for the limiting ball 52 to be mounted. The notches of the rubber strip are mounted on the pillar 51 on the same side of the movable splint 2 and the fixed splint 1.

[0036] Reference Figure 2 In order to reduce the damage of the product and the load due to clamping when the movable clamping plate 2 and the fixed clamping plate 1 are close to each other, rubber pads 7 made of silicone rubber are fixedly provided on the opposite sides of the movable clamping plate 2 and the fixed clamping plate 1.

[0037] Reference Figure 2In order to reduce the wear caused by the nut's resistance to the movable clamping plate 2 when the threaded rod 32 rotates, a washer 8 is provided between the nut and the movable clamping plate 2, and the washer 8 is sleeved on the threaded rod 32.

[0038] The implementation principle of the second embodiment is that the connecting rope 6 between the movable clamping plate 2 and the fixed clamping plate 1 can reduce the time wasted by the operator in searching for the matching fixed clamping plate 1 and the movable clamping plate 2 during use. The rubber strip is sleeved on the support 51 on the same side of the movable clamping plate 2 and the fixed clamping plate 1, and the distance between the movable clamping plate 2 and the fixed clamping plate 1 is shortened through the elastic recovery performance of the silicone rubber, and the support rod part of the product and the load couple are initially clamped and fixed, so that the operator can rotate the nut to finally fix the support rod part of the product and the load couple.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
