Description

Technical Field

[0001] The utility model relates to the technical field of casting production, in particular to a multi-angle clamping device for cleaning castings. Background Art

[0002] Theory of Casting Molding Metal liquid molding is often called casting. Casting molding technology has a long history. Castings are metal molded objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods. After cooling and subsequent processing such as grinding, the resulting object has a certain shape, size and performance. At present, after the casting is formed, the excess parts of the casting need to be cleaned and polished as a whole.

[0003] For example, the public document with application number 202220238220.8 discloses a multi-angle clamping device for cleaning castings. The utility model can realize two fixing methods, namely clamping and vacuum adsorption, and can improve the fixing effect of the castings. At the same time, it can drive the castings to rotate, so that the castings can be cleaned in multiple directions, thereby improving the use effect. However, when clamping the castings, the multi-angle clamping device for cleaning castings only fixes and clamps the two sides of the castings. For special-shaped castings with different corners, only the two sides are clamped, and no effective limit is set on the upper and lower parts, which may cause a single two sides to be subjected to force. In combination with the front side being subjected to force during grinding and cleaning, the front and rear upper and lower sides of the castings are subjected to uneven force, resulting in gradual displacement of the castings, uneven clamping pressure, and slippage through the upper and lower sides, thereby affecting the stability of the clamping and fixation of the castings, and also affecting the stability of the grinding and cleaning work of the castings.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a multi-angle clamping device for casting cleaning is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 4As shown, a multi-angle clamping device for casting cleaning includes a base plate 1, a lifting mechanism 2 is fixedly installed above the surface of the base plate 1, a fixing plate 3 is installed on the upper end of the lifting mechanism 2, an electric telescopic rod 4 is rotatably penetrated through the middle of the surface of the fixing plate 3, a driving motor 5 is fixedly installed on the left end of the fixing plate 3, the right end of the driving motor 5 is connected to the electric telescopic rod 4, a fixing mechanism 6 is arranged on the right end of the electric telescopic rod 4, and a limiting mechanism 7 is arranged inside the fixing mechanism 6.

[0024] By adopting the above technical solution, the height and extension length of the casting clamping can be adjusted by using the lifting mechanism 2 and the electric telescopic rod 4, and the driving motor 5 can drive the clamping device to rotate through the electric telescopic rod 4, thereby changing the angle of the casting after clamping;

[0025] The fixing mechanism 6 and the limiting mechanism 7 simultaneously perform different clamping and limiting operations on the casting, thereby effectively and firmly clamping and fixing the casting to prevent the casting from falling off or loosening.

[0026] Furthermore, the lifting mechanism 2 includes a sleeve 201 fixedly installed on the left end above the surface of the base plate 1 , and guide grooves 202 are provided on both left and right sides of the inner surface of the sleeve 201 , and guide blocks 203 are slidably provided on the inner surface of the guide groove 202 .

[0027] By adopting the above technical solution, the guide block 203 can slide up and down inside the guide groove 202, and the guide groove 202 limits the guide block 203 to rotate forward and backward.

[0028] Furthermore, the lifting mechanism 2 also includes an adjusting cylinder 204 fixedly installed in the middle of one end opposite to the guide block 203, the inner surface of the adjusting cylinder 204 is threadedly connected with a screw rod 205, the bottom end of the screw rod 205 is provided with a rotating motor 206, the rotating motor 206 is fixedly arranged on the inner surface of the sleeve 201, and the top end of the outer surface of the adjusting cylinder 204 is connected to the fixed plate 3.

[0029] By adopting the above technical solution, when the screw rod 205 is rotated by the rotating motor 206, since the adjustment cylinder 204 is fixed to the guide block 203 and is limited by the guide groove 202, the adjustment cylinder 204 will not rotate with the screw rod 205, but will be pushed up and down by the thread to adjust the height.

[0030] Furthermore, the fixing mechanism 6 includes an assembly frame 601 fixedly installed at the right end of the electric telescopic rod 4, a bidirectional screw 602 is rotatably arranged in the middle of the inner surface of the assembly frame 601, and a servo motor 603 is installed at the right end of the bidirectional screw 602 passing through the assembly frame 601.

[0031] By adopting the above technical solution, the servo motor 603 is fixed to the rear end of the outer surface of the assembly frame 601 , and provides rotational power to the bidirectional screw 602 .

[0032] Furthermore, the fixing mechanism 6 also includes two movable plates 604 threadedly connected at both ends of the surface of the bidirectional screw 602, and a clamping plate 605 is fixedly provided at one end of the movable plate 604 away from the assembly frame 601, and a suction cup cone head rod 606 is slidably penetrated through the inner middle of the surface of the clamping plate 605.

[0033] By adopting the above technical solution, the surface of the movable plate 604 is slidably fitted with the inner surface of the groove of the assembly frame 601. When the bidirectional screw 602 rotates, the inner surface of the groove can limit the movable plate 604, thereby forcing the movable plate 604 to be pushed by the thread to drive the clamping plate 605 to move;

[0034] The suction cup cone head rod 606 will contact the casting first. As the clamping plate 605 continues to press, the rubber suction cup head will absorb the casting, further improving the stability of the casting clamping, and can provide a certain buffer protection for the casting clamping to avoid wear of the casting caused by hard contact.

[0035] Furthermore, the limiting mechanism 7 includes two sliding grooves 701 symmetrically opened on the upper and lower sides of the inner surface of the clamping plate 605 away from the suction cup cone head rod 606, and a slider 702 is slidably arranged on the inner surface of the sliding groove 701. A push plate 703 is fixedly installed at one end of the slider 702, and the upper and lower ends of the surface of the push plate 703 close to the suction cup cone head rod 606 are both arranged as inclined surfaces.

[0036] By adopting the above technical solution, the sliding groove 701 and the slider 702 make the push plate 703 move more stably;

[0037] The inclined surfaces at the upper and lower ends of the push plate 703 enable the push plate 703 to be pushed and moved by the pointed cone end of the suction cup cone head rod 606.

[0038] Furthermore, the limiting mechanism 7 also includes springs 705 fixedly installed on the upper and lower ends of the inner surface of the clamping plate 605, and a baffle 704 is fixedly installed on one end of the spring 705. The baffle 704 slides through the clamping plate 605, and the push plate 703 is located in the middle of the baffle 704 and does not contact the spring 705.

[0039] By adopting the above technical solution, the inclined surface at the other end of the push plate 703 will push the baffle 704 to extend out of the clamping plate 605, thereby blocking the upper and lower ends of the clamping plate 605, that is, limiting the upper and lower ends of the middle clamped casting, to prevent the casting from flying out through the openings at the upper and lower ends;

[0040] The spring 705 can pull the baffle plate 704 to shrink and reset. When the baffle plate 704 is reset, the inclined surface of the push plate 703 is used to reset the entire limiting mechanism 7 including the suction cup cone head rod 606.

[0041] Working principle: When using the multi-angle clamping device for cleaning castings, first, place the casting between the two side clamps 605, and the servo motor 603 drives the bidirectional screw 602 to rotate. Under the sliding limit of the movable plate 604 by the groove of the assembly frame 601, the movable plate 604 is forced to drive the clamp 605 to move toward the middle, so as to fix and clamp the casting. When the clamp 605 clamps the casting, the suction cup cone head rod 606 will first contact the casting. As the clamp 605 continues to press, the colloid suction cup head will absorb the casting, further improving the stability of the casting clamping. When the suction cup cone head rod 606 first contacts the casting, it will shrink a certain distance into the inside of the clamp 605 through its own rod body. The suction cup cone head rod 606 uses its own pointed cone end and the inclined surface of the push plate 703. When the pointed cone end shrinks and moves, it will push the push plate 703 to use the sliding groove 701 and the slider 702. The limit sliding moves up and down respectively, and through the inclined surface at the other end of the push plate 703, it will push the baffle 704 to extend out of the clamping plate 605, thereby blocking the upper and lower ends of the clamping plate 605, that is, limiting the upper and lower ends of the middle clamped casting, so that the casting can be completely, effectively and stably clamped. After the clamping is completed, according to the needs of different cleaning and polishing, the rotating motor 206 uses positive and negative rotation to drive the screw rod 205 to rotate forward and backward. Under the limitation of the adjusting cylinder 204 by the guide block 203 through the guide groove 202, the adjusting cylinder 204 is subjected to the thread pushing force of the rotating screw rod 205, and moves up and down to adjust the height of the entire clamping device. At the same time, the extension length of the entire clamping device can be adjusted by the electric telescopic rod 4, and the driving motor 5 can be used to rotate the clamping device to adjust the angle of the casting, thereby adjusting and cleaning the casting at multiple angles. This is the working principle of the multi-angle clamping device for casting cleaning.
