Description

Technical Field

[0001] This invention belongs to the field of fixture technology, specifically, it relates to a tooling fixture and a fixture rotation device. Background Technology

[0002] Machining refers to the process of changing the shape, size, or properties of a workpiece using mechanical equipment. Based on the processing method, it can be divided into cutting and pressure processing. When machining parts, tooling fixtures are used; these are also called jigs. Broadly speaking, any device used to quickly, conveniently, and safely install a workpiece during any step of the manufacturing process can be called a fixture; examples include welding fixtures, inspection fixtures, assembly fixtures, and machine tool fixtures. Machine tool fixtures are the most common and are often simply referred to as fixtures.

[0003] The current fixtures require workers to constantly disassemble and reassemble the device to adjust the angle when machining polygonal columns, which delays work time and reduces work efficiency; moreover, the angle adjustment requires manual adjustment and cannot determine the accuracy of the angle adjustment.

[0004] In summary, there is a need to invent a tooling fixture and a fixture rotation device to solve the above problems. Summary of the Invention

[0005] In view of the above-mentioned prior art, the purpose of the present invention is to provide a tooling fixture and a fixture rotation device to solve the problems mentioned in the background art, which require workers to constantly disassemble and reassemble the device to adjust the angle when processing polygonal columns, thus delaying work time, reducing work efficiency, and making it impossible to determine the accuracy of angle adjustment by manually adjusting the angle.

The tooling fixture includes multiple clamping plates, a support plate, multiple L-shaped swing support rods, and a threaded hole ring seat. The bottom of the upper outer shell is rotatably connected to the top of the lower outer shell. A threaded rod is rotatably connected between the top of the upper outer shell and the bottom of the lower outer shell. A gear is fixedly connected to the lower outer wall of the threaded rod, and the gear is located inside the lower outer shell. The lower end of the threaded rod is fixedly connected to the first handle, which drives the threaded rod to rotate. The first handle is located on the outer side of the bottom of the lower outer shell. A double locking mechanism is installed on the lower right side of the lower outer shell, and the double locking mechanism locks the threaded rod, facilitating the upper and lower outer shell rotation. The shell completes the angle adjustment. The threaded hole ring seat is threaded onto the outer wall of the upper end of the threaded rod. The rotation of the threaded rod causes the threaded hole ring seat to move up and down. Multiple second U-shaped connecting seats are fixedly connected to the wheel edge of the threaded hole ring seat. Multiple opening grooves are opened on the upper end of the outer wall of the upper shell. The positions of the multiple opening grooves correspond to the positions of the multiple second U-shaped connecting seats.

A first spring is sleeved on the outer wall of the middle of the first anti-detachment plug post, and the first spring is located inside the middle of the second middle-character anti-detachment groove. Through the expansion and contraction of the first spring, it is convenient for the first anti-detachment plug post to reciprocate inside the second middle-character anti-detachment groove, so that the first anti-detachment plug post extends into the multiple sawtooth grooves of the gear.

[0042] In this invention, such as Figures 8 to 12As shown, the outer shapes of both the first anti - detachment plug post 13 and the second anti - detachment plug post 24 are cross - shaped cylinders, and one end of the cylinder in the vertical direction is a bevel. The first middle - shaped anti - detachment groove 25 is provided in the middle of the cylinder of the first anti - detachment plug post 13 in the vertical direction. The first spring 14 is sleeved on the outer wall of the cylinder of the first anti - detachment plug post 13 in the vertical direction, and one end of the first spring 14 contacts the transverse cylinder of the first anti - detachment plug post 13. The second spring 26 is sleeved on the outer wall of the cylinder of the second anti - detachment plug post 24 in the vertical direction, and one end of the second spring 26 contacts the transverse cylinder of the second anti - detachment plug post 24. The second handle 12 is a T - shaped rotating body, and the bottom is a bevel with an inclination angle consistent with the bevel angles of the first anti - detachment plug post 13 and the second anti - detachment plug post 24. The transverse cylinders at both ends of the first anti - detachment plug post 13 are slidably connected to the wide - mouth grooves of the second middle - shaped anti - detachment groove 27, and the cylinder of the first anti - detachment plug post 13 in the vertical direction is slidably connected to the narrow - mouth groove in the middle of the second middle - shaped anti - detachment groove 27.

The bevel of the second anti - detachment plug post 24 is fixedly connected to the bevel of the second handle 12, and the bevels of the second anti - detachment plug post 24 and the second handle 12 face the same direction. The end of the second anti - detachment plug post 24 away from the bevel is inserted into the inside of the card hole 20, the bevel end of the first anti - detachment plug post 13 contacts the bevel end of the second handle 12, and the end of the first anti - detachment plug post 13 away from the bevel extends into the multiple saw - tooth grooves of the gear 19. When the gear 19 is in the locked state, the bevels of the first anti - detachment plug post 13, the second anti - detachment plug post 24, and the second handle 12 face the same direction and coincide. When the gear 19 is in the unlocked state, the bevel of the first anti - detachment plug post 13 faces the opposite direction to the bevels of the second anti - detachment plug post 24 and the second handle 12, and the length of the second handle 12 pulled out is less than the length of the wide - mouth groove of the second middle - shaped anti - detachment groove 27. When the second handle 12 is pulled outwards, the end of the second anti - detachment plug post 24 away from the bevel is separated from the card hole 20, and by rotating the second handle 12 clockwise, while the left bevel of the second handle 12 contacts the right bevel of the first anti - detachment plug post 13, at this time, the inclination direction of the left bevel of the second handle 12 is opposite to the inclination direction of the right bevel of the first anti - detachment plug post 13, and it also makes the second anti - detachment plug post 24 retract into the inside of the first middle - shaped anti - detachment groove 25, and at this time the second spring 26 is in a compressed state, completing the unlocking work of the gear 19. When the second handle 12 is rotated counter - clockwise, the left bevel of the second handle 12 is separated from the right bevel of the first anti - detachment plug post 13, and the second anti - detachment plug post 24, through the elongation of the second spring 26, makes the end of the second anti - detachment plug post 24 away from the bevel inserted into the inside of the card hole 20, completing the locking work of the gear 19.

[0043] In this invention, one end of each of the four second support columns 11 is fixedly connected to the bottom of the support plate 2, and the other end of each column passes through the through sliding hole at the upper end of the upper shell 3 and is fixedly connected to the top of the threaded hole ring seat 22.

[0044] In this invention, each of the three L-shaped swing support rods 10 has a clamp 1 fixedly connected to the end away from the upper outer shell 3, and the end closer to the upper outer shell 3 is rotatably connected to the three second U-shaped connecting seats 21 through the connecting block 17. The middle part of each of the three L-shaped swing support rods 10 is rotatably connected to the interior of the three open grooves 9 through the connecting shaft.

[0045] In this invention, the first anti-detachment post 13, the second anti-detachment post 24, and the second handle 12 are all welded assemblies.

[0046] The working principle and usage process of this invention are as follows: First, the base 7 is installed in the designated position using bolts. Then, the worker places the part to be processed on the support plate 2. Next, the worker pulls the second handle 12 outwards, i.e., away from the lower outer casing 8, causing the second anti-detachment pin 24 to separate from the locking hole 20. By rotating the second handle 12, the left surface of the second handle 12 contacts the right surface of the first anti-detachment pin 13, causing the second anti-detachment pin 24 to retract into the first U-shaped anti-detachment groove 25, thus unlocking the gear 19. Afterwards, the worker rotates the first handle 6 counterclockwise. This will cause the threaded rod 18 to rotate counterclockwise, which will cause the threaded hole ring seat 22 to move downward. Through the three connecting blocks 17, the three L-shaped swing support rods 10 will rotate up and down. This will cause the three clamping plates 1 to clamp and fix the part to be processed on the support plate 2. After the part to be processed is clamped and fixed on the support plate 2, the operator will rotate the second handle 12 in the opposite direction, so that the left side surface of the second handle 12 separates from the right side surface of the first anti-detachment insert 13. Through the free extension of the second spring 26, the second anti-detachment insert 24 is inserted into the card hole 20, which can lock the gear 19, thus facilitating the processing of the part to be processed.

[0047] When the angle needs to be adjusted, the operator pulls the second handle 12 outward to unlock the gear 19. Then, by rotating the upper shell 3 counterclockwise, the four second support columns 11 drive the threaded hole ring seat 22 to rotate counterclockwise. Since the three clamping plates 1 clamp the workpiece, the rotation of the threaded hole ring seat 22 will drive the threaded rod 18 to rotate, thereby driving the gear 19 to rotate. At this time, through the rotation of the gear 19 and the extension and retraction of the first spring 14, the first anti-detachment insert 13 will slide back and forth inside the second T-shaped anti-detachment groove 27. Since the gear 19 has multiple serrated grooves, when the first anti-detachment insert 13 contacts the multiple serrated grooves in the gear 19, the angle of the upper shell 3, the tooling fixture and the workpiece can be precisely adjusted. After the angle is adjusted, the operator operates the second handle 12 in the opposite direction to lock the gear 19, so that the workpiece can be processed at multiple angles.

[0048] During the entire operation, the deformation of the rubber support rod 16 in the three buffer mechanisms can achieve a buffering effect, thereby dispersing the downward pressure acting on the threaded rod 18, improving the service life of the threaded rod 18, and facilitating angle adjustment. In addition, since the rubber support rod 16 is made of rubber, it can return to its initial state according to its physical properties, thus improving its service life.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
