Description

Technical Field

[0001] The utility model belongs to the technical field of clamping mechanisms, in particular to a non-standard automatic clamping mechanism. Background Art

[0002] Non-standard automation, as the name implies, refers to a non-standard automation equipment specially customized according to the actual production process requirements of the product. The functions can be increased or decreased according to the needs of the user, and the degree of customization is high. It is often used in the fields of industry, electronics, medical treatment, sanitation, and aerospace. When using non-standard automation equipment to process workpieces, a clamping mechanism is required to clamp and fix the workpiece.

[0003] Publication No. "CN219987398U" discloses "a clamping mechanism for non-standard automation equipment". Through the setting of vertical plates, long rods and other structures, the second crank handle is shaken, and the rotating rod rotates to drive the first bevel gear to rotate, and the first bevel gear drives the second bevel gear to rotate. The second bevel gear rotates to drive the lifting plate to move up and down, and the lifting plate drives the horizontal column and the bottom plate to move, thereby achieving the effect of adjusting the height of the clamping mechanism according to the size of the object. At the same time, through the setting of bases, wheels and other structures, when the workpiece inspection is completed, the object is released and the entire clamping mechanism is pushed to the next workpiece to be inspected for direct inspection. This can prevent inaccurate subsequent measurements after disassembling and reinstalling the mechanism, thereby achieving the effect of convenient movement.

[0004] The above-mentioned prior art still has the following disadvantages in the specific implementation process:

[0005] Since the long rod is rotatably connected to the vertical plate, when the clamped workpiece needs to be flipped and adjusted, the first crank handle needs to be manually rotated to drive the clamped workpiece to flip in the vertical direction. However, there is a lack of a corresponding limiting mechanism. Due to the effect of gravity, the workpiece cannot be stably kept at the flipped angle, and the directions of the two movable clamps cannot be adjusted. When it is necessary to clamp workpieces in different directions, the entire clamping mechanism needs to be adjusted to move. The operation is relatively cumbersome and it is not convenient to clamp workpieces in different directions, which affects the use effect of the clamping mechanism.

[0006] To solve the above problems, we propose a non-standard automatic clamping mechanism. Utility Model Content

[0028] The clamping assembly is used to clamp and fix the workpiece, and the height of the clamping mechanism is adjusted in combination with the lifting mechanism. Under the rotational cooperation between the support shaft 6 and the vertical plate 5, the clamping assembly is used to facilitate the flipping and adjustment of the clamped workpiece. Under the active cooperation between the movable rod 14 and the vertical plate 5, combined with the elastic effect of the spring 13, and the sliding cooperation between the guide plate 10 and the guide rod 9, the guide plate 10 is pressed downward, driving the movable block 11 to approach the direction of the support shaft 6, and then driving the clamping block 12 to be inserted downward into the corresponding clamping groove 7, effectively limiting the support shaft 6, preventing the support shaft 6 from rotating freely, and ensuring that the clamped workpiece can stay stably at the flipped angle, solving the problem in the prior art that the long rod is rotatably connected to the vertical plate 5 when the clamping is required. When the workpiece is flipped and adjusted, it is necessary to manually rotate the first crank handle to drive the clamped workpiece to flip in the vertical direction, but there is a lack of corresponding limiting mechanism. Due to the effect of gravity, the workpiece cannot be stably kept at the flipped angle. At the same time, combined with the shaft effect between the disc 2 and the bracket 4, it is convenient to flexibly adjust the bracket 4 for rotation, and then adjust the orientation of the clamping assembly, which is convenient for clamping workpieces in different directions. Combined with the positioning piece, the bracket 4 is fixed to ensure the stability of the clamping assembly, which solves the problem that the orientation of the two movable clamps cannot be adjusted in the prior art. When it is necessary to clamp workpieces in different directions, it is necessary to adjust the entire clamping mechanism to move, which is cumbersome to operate and is not convenient for clamping workpieces in different orientations, affecting the use effect of the clamping mechanism.

A plurality of positioning grooves 17 are evenly arranged on the upper surface of the disc 2 in a circular shape. The first screw 18 is threadedly matched with the bracket 4. The positioning rod 19 is fixed at the lower end of the first screw 18, and the positioning rod 19 is matched with the positioning groove 17.

[0031] The clamping assembly includes a first movable clamp 21, a second movable clamp 22, a motor 23 and a second screw 24. The second movable clamp 22 is fixedly connected to the end of the support shaft 6 away from the handle 20. The motor 23 is installed on the second movable clamp 22. The second screw 24 is connected to the output shaft of the motor 23. The first movable clamp 21 and the second screw 24 are threadedly matched. Two support rods are fixed on the second movable clamp 22. The support rods pass through the first movable clamp 21, and the first movable clamp 21 and the support rods are movably matched. The support rods and the ends of the second screw 24 away from the second movable clamp 22 are fixed with limit blocks.

[0032] The lifting mechanism includes a lifting rod 3, a fixed column 25, a rotating rod 26, an active bevel gear 27, a driven bevel gear 28, a screw 29 and a movable disk 30. The fixed column 25 is fixed on the base 1, the rotating rod 26 is rotatably set inside the base 1, the screw 29 is rotatably set inside the fixed column 25, the active bevel gear 27 is set on the rotating rod 26, the driven bevel gear 28 is fixed at the bottom of the screw 29, and the active bevel gear 27 is meshed with the driven bevel gear 28. The movable disk 30 is threadedly set on the screw 29, and several lifting rods 3 are fixed on the movable disk 30. Several circular holes are penetrated at the top of the fixed column 25. The upper end of the lifting rod 3 passes through the circular hole and is connected to the bottom of the disk 2. The right end of the rotating rod 26 is connected to a hand wheel.

[0033] A plurality of rollers 31 are installed at the bottom of the base 1 . A third screw rod 32 is threadedly arranged on the base 1 . A rubber plate 33 is connected to the bottom of the third screw rod 32 .

[0034] Example:

[0035] When in use, first, the clamping mechanism is moved as a whole under the action of the roller 31. After the clamping mechanism is moved as a whole to a suitable position, the third screw 32 is adjusted to rotate downward under the cooperation of the threads of the third screw 32 and the base 1 until the rubber plate 33 is driven to move downward to contact the ground, thereby increasing the contact area and friction between the bottom of the base 1 and the ground, and then the bottom of the clamping mechanism is limited and fixed to ensure the stability of the clamping mechanism as a whole during use;

[0036] Then, the motor 23 is started, and the second screw 24 is driven to rotate by the motor 23. In combination with the threaded cooperation between the first movable clamp 21 and the second screw 24, and the sliding cooperation between the first movable clamp 21 and the support rod, the first movable clamp 21 is adjusted to move closer to the second movable clamp 22, so as to achieve the purpose of clamping and fixing the workpiece.

[0037] When adjusting the height of the clamping mechanism, the hand wheel is turned to drive the rotating rod 26 to rotate, and the meshing action of the active bevel gear 27 and the driven bevel gear 28 drives the screw rod 29 to rotate.

[0038] When the clamped workpiece needs to be flipped and adjusted, the connecting plate 15 is pulled upward through the pull ring 16, and under the action of the movable rod 14, the guide plate 10 is driven to move upward along the direction of the guide rod 9, and the spring 13 is squeezed, and combined with the movable block 11, the clamping block 12 is driven upward away from the clamping groove 7, and then the handle 20 is turned to adjust the support shaft 6 to rotate, thereby flipping and adjusting the clamped workpiece;

[0039] After the workpiece is flipped to a suitable angle, the pull ring 16 is released, and the guide plate 10 is pressed downward under the elastic action of the spring 13, driving the movable block 11 to move in the direction of the support shaft 6, and then driving the clamping block 12 to insert downward into the corresponding clamping groove 7, effectively limiting the support shaft 6, so that the clamped workpiece stays stably at the adjusted angle, solving the problem in the prior art that due to the rotational connection between the long rod and the vertical plate 5, when the clamped workpiece needs to be flipped and adjusted, it is necessary to manually rotate the first crank handle to drive the clamped workpiece to flip in the vertical direction, but there is a lack of a corresponding limiting mechanism, and due to the action of gravity, the workpiece cannot stay stably at the flipped angle;

[0040] When it is necessary to clamp workpieces in different directions, the first screw 18 is adjusted to rotate upward, driving the positioning rod 19 upward away from the corresponding positioning groove 17, and then, under the action of the rotating shaft between the bracket 4 and the disc 2, the bracket 4 is adjusted to rotate around the rotating shaft as the center, and combined with the vertical plate 5, the clamping assembly is driven to rotate, so as to achieve the purpose of adjusting the direction of the clamping assembly, which is convenient for clamping and fixing workpieces in different directions, and solves the problem that the orientation of the two movable clamps cannot be adjusted in the prior art. When it is necessary to clamp workpieces in different directions, the entire clamping mechanism needs to be adjusted to move, which is cumbersome to operate and is not convenient for clamping workpieces in different directions, affecting the use effect of the clamping mechanism;

[0041] After the bracket 4 is rotated to a suitable angle, the first screw 18 is adjusted to rotate downward, driving the positioning rod 19 downward and inserting it into the corresponding positioning groove 17 to limit and fix the bracket 4, thereby making the clamping assembly stably stay in the adjusted direction, facilitating the use of the clamping mechanism.
