Technical Field

[0001] The utility model relates to the technical field of fixing equipment, in particular to a mechanical design workpiece fixing equipment. Background Art

[0002] Mechanical design refers to the designer using mechanical principles and engineering knowledge to organically combine the various components of mechanical equipment to meet specific functional and performance requirements. In the process of mechanical design, designers need to comprehensively apply relevant knowledge such as mechanical engineering, material science, mechanics, dynamics, fluid mechanics, etc., and combine actual application requirements and manufacturing processes to design safe, reliable and high-performance mechanical equipment. The process of mechanical design usually includes the following steps: demand analysis, conceptual design, detailed design, manufacturing and processing, testing and verification.

[0003] During the manufacturing process, the rough workpiece needs to be fixed and then processed. In the prior art, two or more clamping blocks are often used to clamp the tubular workpiece from the outside of the tubular part. After clamping, the outer surface of the fixed end cannot be directly exposed, which makes it inconvenient to process the outer surface of the fixed end of the tubular workpiece.

[0024] Embodiment 1, in combination with the attached Figure 1 , 2 、4.

[0025] A mechanical workpiece fixing device comprises a base 1 and a clamping mechanism 2, wherein the base 1 is provided with a rotary drive device, the clamping mechanism 2 is fixedly mounted on the output shaft of the rotary drive device, the clamping mechanism 2 comprises a sleeve 3, a clamping block 4, a pushing member 5 and a power component 6; one end of the sleeve 3 is fixed on the rotary drive device, and the end away from the rotary drive device is provided with a plurality of through-hole slide grooves 7 along the circumferential direction, the clamping block 4 is provided with a plurality of through-hole slide grooves 7, which are respectively slidably arranged in the corresponding through-hole slide grooves 7; a trapezoidal slide groove 8 is provided on the inner side of the clamping block 4, and a trapezoidal push block 9 is correspondingly provided around the push member 5, and the inclined surfaces of the two are in contact with each other; the power component 6 drives the push member 5 to be slidably arranged in the sleeve 3, and drives the trapezoidal push block 9 to slide in the trapezoidal slide groove 8, so that the clamping block 4 can be pushed out.

[0026] The power component 6 drives the pushing member 5 to slide along the sleeve 3, which can drive the trapezoidal push block 9 to move along the trapezoidal slide groove 8. Due to the contact between the inclined surfaces of the two, when the trapezoidal push block 9 moves toward the end away from the base, the clamping block 4 can be pushed outward, thereby clamping the tubular part from the inside, making it convenient to process the outer surface of the fixed end of the tubular part.

[0027] Embodiment 2, combined with the attached Figure 2 , 4 .

[0028] The power component 6 is a rod-shaped structure, which is rotatably arranged in the sleeve 3. A threaded section 10 is provided on the power component 6, and a threaded hole is correspondingly provided on the pusher 5, and the pusher 5 is threadedly connected to the power component 6 through the threaded hole.

[0029] The power component 6 is provided with a worm wheel 11 at one end close to the rotary drive device, and a worm 12 is meshed on the worm wheel 11. The worm 12 is rotationally connected to the side wall of the sleeve 3. The worm wheel 11 and the worm 12 meet the self-locking condition of the worm gear transmission.

[0030] One end of the worm 12 extends out of the sleeve 3 and is provided with a wrench groove 13 .

[0031] The worm gear 11 is driven to rotate by the rotation of the worm 12, thereby driving the power component 6 to rotate. Since the power component 6 is threadedly connected to the pusher 5, the pusher 5 is restricted by the trapezoidal push block 9 and the trapezoidal slide groove 8 and cannot rotate with the power component 6. Therefore, when the power component 6 rotates, the pusher 5 slides axially along the sleeve 3, thereby driving the trapezoidal push block 9 to slide along the trapezoidal slide groove 8.

[0032] Embodiment 3, in combination with the attached Figure 2 , 4 .

[0033] The length direction of the through hole slide groove 7 is perpendicular to the axial direction of the sleeve 3 .

[0034] A limit stopper 14 is disposed on the inner wall of the clamping block 4 , and a limit slide groove 15 is correspondingly disposed on the side wall of the through hole slide groove 7 . The outer end of the limit slide groove 15 is sealed, and the limit stopper 14 is slidably disposed in the limit slide groove 15 .

[0035] A spring 16 is disposed in the limiting slide groove 15 , and two ends of the spring 16 are respectively in contact with the limiting stopper 14 and the end wall of the limiting slide groove 15 .

[0036] The limit stopper 14 and the limit slot 15 are provided to prevent the clamping block 4 from being separated from the sleeve, and a spring 16 is provided between the limit stopper 14 and the end wall of the limit slot 15, so that when the pusher 5 moves toward one side of the base 1, the spring 16 drives the clamping block 4 to reset, making it convenient to remove the tubular parts clamped thereon.

[0037] When the utility model is implemented, a wrench is inserted into the wrench slot 13, and the worm 12 is driven to rotate through the wrench, and the worm wheel 11 and the power component 6 are driven to rotate, which can drive the pusher 5 to slide along the sleeve. When the pusher 5 moves toward the end away from the base 1, the clamping block 4 is pushed outward. When it moves toward the end close to the base 1, the spring 16 drives the clamping block 4 to reset.

[0038] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
