Description

Technical Field

[0001] This utility model relates to the field of fixture and tooling technology, and in particular to an auxiliary fixture for ductile iron profiles. Background Technology

[0002] Ductile iron profiles are a type of cast iron material that is processed using a special process to make the graphite in the cast iron exist in a spherical form, thereby significantly improving the toughness and strength of the cast iron. During the processing of ductile iron profiles, the outer surface of the ductile iron profiles is treated. At this time, a fixture is used to clamp the ductile iron profiles before processing, which plays a positioning role for the ductile iron profiles.

[0003] Some existing clamps, when clamping, have their clamping plates in contact with the outer surface of the tubular ductile iron profile, which will cover part of the ductile iron profile. The covered area can only be sprayed after the clamping plates are released, which is a cumbersome operation.

[0004] The existing publicly available technical solution, CN218132729U, discloses an auxiliary tooling for clamping ductile iron profiles. The auxiliary tooling body includes a main body with a base fixed to its upper end. A rotating platform is rotatably connected to the base. A clamping mechanism for holding ductile iron profiles is installed on the right side of the rotating platform. By separating the clamping column and clamping rod, the inclined surfaces of two first positioning blocks and two second positioning blocks move to separate and support the inner wall of the end of the ductile iron profile, quickly supporting and clamping the tubular ductile iron profile, ensuring clamping efficiency. Furthermore, by horizontally sliding the first and second positioning blocks, the horizontal distance between the two first and two second positioning blocks can be adjusted, facilitating the clamping of ductile iron profiles of different lengths within a certain range.

[0005] In actual implementation of the above technical solution, since the pedestal is fixed above the tooling body, the tubular ductile iron profile can only be fitted outside the clamping column between the clamping column and the bearing. However, the distance between the clamping column and the bearing is limited. If the tubular ductile iron profile is long, the operation is more troublesome when it is fitted outside the clamping column. Summary of the Invention

[0006] The purpose of this utility model is to provide an auxiliary tooling for ductile iron profile clamping, which can make the turntable and the clamping assembly not be on the same vertical plane through the setting of the rotating support assembly, so as to facilitate the installation of tubular ductile iron profiles on the rotating support assembly and solve the problems mentioned in the background art.

[0008] The rotating support assembly includes a turntable installed inside the fixture base plate, and a rotating rod is fixedly installed on the top of the turntable. A rotating plate is fixedly installed on the top of the rotating rod, and a turntable is rotatably installed inside the rotating plate. Two sets of support plates are vertically arranged on one side of the turntable. Fixing holes are opened on the top of both the turntable and the fixture base plate, and fixing rods pass through the fixing holes.

[0009] Preferably, the rotating bracket assembly further includes a clamping plate fixedly disposed on the surface of the support plate, and a clamping spring is disposed between the clamping plate and the support plate, as well as a guide telescopic rod passing through the clamping spring.

[0013] Preferably, the clamping assembly includes a movable plate slidably mounted on the top of the fixture base plate, a limiting groove is provided at the connection between the fixture base plate and the movable plate, and a limiting slider is installed inside the limiting groove.

[0024] 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.

[0025] This utility model provides a technical solution:

[0026] Please see Figures 1 to 4 A fixture for ductile iron profiles includes a fixture base plate 1, a rotating bracket assembly 3 rotatably mounted on the fixture base plate 1, and a clamping assembly 4 slidably mounted on the top of the fixture base plate 1 on one side of the rotating bracket assembly 3. A stepper motor 2 is fixedly mounted on one side of the rotating bracket assembly 3.

[0027] The rotating support assembly 3 includes a turntable 307 installed inside the fixture base plate 1, and a rotating rod 302 is fixedly installed on the top of the turntable 307. A rotating plate 301 is fixedly installed on the top of the rotating rod 302, and a turntable 303 is rotatably installed inside the rotating plate 301. Two sets of support plates 304 are vertically arranged on one side of the turntable 303. Fixing holes 308 are opened on the top of both the turntable 307 and the fixture base plate 1, and fixing rods 5 pass through the inside of the fixing holes 308.

[0028] By adopting the above technical solution, when it is necessary to install tubular ductile iron profiles on the rotating bracket assembly 3, the rotating rod 302 can be rotated. At this time, the rotating rod 302 drives the rotating plate 301 and the turntable 303 to rotate. At this time, the turntable 303 and the clamping assembly 4 are not on the same vertical plane, so the tubular ductile iron profiles can be easily installed on the rotating bracket assembly 3. When it is necessary to clamp and fix the tubular ductile iron profiles, the rotating rod 302 can be rotated to reset it, and the fixing rod 5 can be inserted into the fixing hole 308 to limit the rotation bracket assembly 3. The power output end of the stepper motor 2 is connected to the turntable 303. The stepper motor 2 can drive the turntable 303 to rotate, thereby driving the tubular ductile iron profiles installed on the rotating bracket assembly 3 to rotate, which facilitates the surface treatment of the tubular ductile iron profiles.

[0029] Specifically, such as Figures 2 to 4 As shown, the rotating support assembly 3 also includes a clamping plate 309 fixedly mounted on the surface of the support plate 304, and a clamping spring 313 is provided between the clamping plate 309 and the support plate 304, and a guide telescopic rod 314 passing through the clamping spring 313. The two ends of the guide telescopic rod 314 are fixedly fixed on the clamping plate 309 and the support plate 304 respectively. A lifting slider 305 is fixedly mounted on one end of the support plate 304. A lifting groove is provided at the connection between the lifting slider 305 and the turntable 303. A two-way screw 310 is connected inside the lifting slider 305 through a screw sleeve. A transmission worm gear 311 is fixedly mounted in the middle of the two-way screw 310, and a transmission worm 312 is meshed on one side of the transmission worm gear 311. A knob 306 is fixedly connected to the end of the transmission worm 312 through the turntable 303.

[0030] By adopting the above technical solution, rotating the knob 306 drives the transmission worm gear 312 to rotate, which in turn drives the transmission worm wheel 311 to rotate. The transmission worm wheel 311 then drives the double-acting lead screw 310 to rotate. Through the lead screw sleeve on the double-acting lead screw 310, the two sets of lifting sliders 305 move in opposite directions, thereby adjusting the distance between the two sets of lifting sliders 305. As the distance between the support plates 304 decreases, the tubular ductile iron profile can be fitted onto the outside of the support plate 304, and the support... The clamping plate 309 on the support plate 304 is located inside the tubular ductile iron profile. Rotating the knob 306 in the opposite direction increases the distance between the support plates 304 until the clamping plate 309 is pressed against the tube wall of the tubular ductile iron profile. At this time, the clamping spring 313 and the guide telescopic rod 314 can be squeezed inward, and the elastic force of the clamping spring 313 is used to press the tubular ductile iron profile in the opposite direction. The clamping plate 309 can be made of rubber so that the clamping plate 309 can better fit against the tube wall of the tubular ductile iron profile.

[0031] Specifically, such as Figure 1 As shown, the clamping assembly 4 includes a movable plate 401 that is slidably mounted on the top of the fixture base plate 1. A limiting groove 405 is provided at the connection between the fixture base plate 1 and the movable plate 401, and a limiting slider 404 is installed inside the limiting groove 405. A clamping plate 402 is rotatably mounted inside the movable plate 401. The telescopic end of a clamping cylinder 403 is fixedly connected to one side of the limiting slider 404. The clamping cylinder 403 is fixedly mounted on one side of the fixture base plate 1 by external bolts.

[0032] By adopting the above technical solution, the clamping cylinder 403 is activated and, under the action of the telescopic end, pushes the limiting slider 404 to slide inside the limiting groove 405, thereby causing the movable plate 401 to move towards the rotating bracket assembly 3 until the clamping plate 402 and the end of the tubular ductile iron profile are in contact with each other, thereby clamping the tubular ductile iron profile. When the length of the tubular ductile iron profile is short, a compensation sleeve is installed on the outside of the clamping plate 309. The compensation sleeve is located between the tubular ductile iron profile and the turntable 303, so that one end of the tubular ductile iron profile can be tightly attached to the clamping plate 402.

[0033] Working principle: Rotating the rotating rod 302 causes the rotating plate 301 and the turntable 303 to rotate. At this time, the turntable 303 and the clamping assembly 4 are not on the same vertical plane, which facilitates the installation of the tubular ductile iron profile on the rotating bracket assembly 3. When it is necessary to clamp and fix the tubular ductile iron profile, the rotating rod 302 can be rotated to reset it, and the fixing rod 5 can be inserted into the fixing hole 308 to limit the rotation bracket assembly 3. Rotating the knob 306 causes the transmission worm gear 312 to rotate, which in turn drives the transmission worm wheel 311 to rotate. The transmission worm wheel 311 then drives the double-acting screw 310 to rotate. Through the screw sleeve on the double-acting screw 310, the two sets of lifting sliders 305 move in opposite directions, thereby adjusting the distance between the two sets of lifting sliders 305. Since the distance between the support plates 304 is reduced, the tubular ductile iron profile can be sleeved on the outside of the support plate 304, and the pressure on the support plate 304... The clamping plate 309 is located inside the tubular ductile iron profile. Reversing the knob 306 increases the distance between the support plates 304 until the clamping plate 309 is pressed tightly against the wall of the tubular ductile iron profile. At this point, the clamping spring 313 and the guide telescopic rod 314 can press inwards, and the elastic force of the clamping spring 313 reverses the pressure on the tubular ductile iron profile. The clamping cylinder 403, under the action of its telescopic end, pushes the limiting slider 404 within the limiting groove 405. The sliding mechanism allows the movable plate 401 to move closer to the rotating support assembly 3 until the clamping plate 402 is in contact with the end of the tubular ductile iron profile, thus clamping the profile. When the tubular ductile iron profile is short, a compensating sleeve is installed on the outside of the clamping plate 309, positioned between the profile and the turntable 303, allowing one end of the profile to be tightly fitted against the clamping plate 402. The power output of the stepper motor 2 is connected to the turntable 303, enabling the turntable 303 to rotate, which in turn rotates the tubular ductile iron profile mounted on the rotating support assembly 3, facilitating surface treatment of the profile.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
